For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

The syringe loading mechanism and loading method according to the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in Figures 1 to 8, the syringe loading mechanism according to an embodiment of the present invention includes: a chain conveying mechanism 21, a conveying channel 22, a material dividing mechanism 23 and a material taking and releasing mechanism 24, the chain conveying mechanism 21 conveys a material tray 13; the conveying channel 22 continuously conveys syringes; the material dividing mechanism 23 is connected to the discharge end of the conveying channel 22, the material dividing mechanism 23 receives the syringes, and arranges a certain number of syringes; the material taking and releasing mechanism 24 is used to grab a certain number of arranged syringes and put them into the material tray 13 at the same time.

Therefore, the present invention has a simple structure. The syringes of the previous process are connected to the dividing mechanism 23 through the conveying channel 22. A certain number of syringes are arranged according to the number of holes in the same row on the material tray 13. Then, the arranged syringes are simultaneously grabbed by the material taking and releasing mechanism 24 and placed on the material tray 13. During the whole process, the progress of syringe loading is improved, and the efficiency of syringe loading is greatly improved.

In conjunction with Figure 2, two positioning mechanisms are symmetrically arranged on the chain conveying mechanism 21. The two positioning mechanisms are close to each other to clamp the material tray 13. The positioning mechanism includes a No. 1 cylinder 211 and a positioning push plate 212. The positioning push plate 212 is located on one side of the conveying path of the material tray 13. The No. 1 cylinder 211 is used to drive the positioning push plate 212 to approach the material tray 13. The positioning push plate 212 is provided with positioning teeth 213 that cooperate with the material tray 13.

In this embodiment, the positioning push plate 212 corresponds to two No. 1 cylinders 211, and the two No. 1 cylinders 211 simultaneously push the positioning push plate 212 to move, and the material tray 13 has a plurality of holes for installing syringes, and the plurality of holes are arranged in a honeycomb shape, that is, the holes in adjacent rows are staggered. Therefore, a plurality of positioning teeth 213 are provided on the positioning push plate 212 to effectively position the material tray 13, thereby ensuring that the material tray 13 is in a stable state when the syringe is loaded.

Specifically, the material dividing mechanism 23 includes a first material baffle plate 231, a second material baffle plate 232 and a material belt assembly 234. The material belt assembly 234 is arranged between the first material baffle plate 231 and the second material baffle plate 232. An arrangement channel is formed between the material belt assembly 234 and the first material baffle plate 231 and the second material baffle plate 232. Multiple syringes move in the arrangement channel in sequence to complete the arrangement.

In this embodiment, the material strip assembly 234 is generally in a waist-shaped structure, and the arrangement channel is a waist-shaped annular channel. The syringe is transported in the arrangement channel and moves to a straight path of the annular channel to complete the arrangement.

Furthermore, the material dividing mechanism 23 also includes a servo motor 233, a mounting base 230 and a quick-release nut 235. The servo motor 233 is arranged on the mounting base 230. The output shaft of the servo motor 233 is detachably connected to the material belt assembly 234 through the quick-release nut 235. A positioning column 2345 is arranged on the material belt assembly 234, and a positioning hole matching the positioning column 2345 is provided on the mounting base 230.

Furthermore, the material belt assembly 234 includes a base 2340, a driving sprocket 2341, a driven sprocket 2342, a chain 2343 and a plurality of material blocks 2344. The driving sprocket 2341 and the driven sprocket 2342 are both rotatably mounted on the base 2340. The chain 2343 is transmission-connected to the driving sprocket 2341 and the driven sprocket 2342. A plurality of material blocks 2344 are evenly mounted on the chain 2343 and move with the chain 2343. A slot matching the syringe is provided on the material block 2344. When the chain 2343 is driven, the syringe in the slot is driven to move in the arrangement channel.

That is to say, the entire material belt assembly 234 is a quick-release structure, the positioning column 2345 is used for positioning between the material belt assembly 234 and the mounting base 230, and the quick-release nut 235 directly connects the driving sprocket 2341 and the output shaft of the servo motor 233 from top to bottom, so that the servo motor 233 can drive multiple material blocks 2344 to circulate.

Among them, one end of the first baffle plate 231 and one end of the second baffle plate 232 form an inlet, which is connected to the discharge end of the conveying channel 22. The other end of the first baffle plate 231 and the other end of the second baffle plate 232 form an outlet. A baffle plate 2346 is provided at the outlet. The baffle plate 2346 is rotatably installed on the base 2340. The baffle plate 2346 is located on the outside of the arrangement channel to block the arranged syringes.

In other words, when the material block 2344 moves to the feed port, the syringe enters the slot on the material block 2344 from the conveying channel 22. Due to the limiting effect of the second baffle plate 232, the syringe follows the material block 2344 to move to the discharge port. At this time, the multiple material blocks 2344 at the discharge port are arranged in a straight line, and the multiple slots corresponding to the multiple material blocks 2344 at the discharge port are equidistant from each other, and correspond to the spacing between the holes in the same row in the material tray 13.

Preferably, a No. 2 cylinder 236 is provided on the mounting base 230, and a push plate 237 is provided at the output end of the No. 2 cylinder 236. The push plate 237 is arranged opposite to the baffle plate 2346. The No. 2 cylinder 236 drives the push plate 237 to move outward so that the arranged syringes are moved out of the slot at the same time.

That is to say, the baffle plate 2346 is provided to prevent the syringe at the discharge port from detaching from the slot after losing its obstruction, and the baffle plate 2346 limits the syringe by the action of the tension spring. In this embodiment, the No. 2 cylinder 236 is provided to drive the push plate 237 to move, thereby opening the baffle plate 2346 and allowing the syringes arranged at the discharge port to move out of the slot at the same time, so that the material taking and discharging mechanism 24 can grab and put them into the material tray 13.

In this embodiment, the material taking and discharging mechanism 24 includes a horizontal driving mechanism 241, a vertical driving mechanism 242, a No. 3 cylinder 243 and a clamping mechanism 244. The horizontal driving mechanism 241 drives the vertical driving mechanism 242 to move along the conveying direction of the material tray 13, the vertical driving mechanism 242 drives the No. 3 cylinder 243 to move in the vertical direction, and the No. 3 cylinder 243 drives the clamping mechanism 244 to move along the arrangement direction of the syringes. The clamping mechanism 244 is used to clamp the arranged syringes at the same time.

Among them, the horizontal driving mechanism 241 and the vertical driving mechanism 242 are both screw driving mechanisms. The movement direction of the horizontal driving mechanism 241 is parallel to the conveying direction of the material tray 13, and the vertical driving mechanism 242 can drive the syringe clamped by the clamping mechanism 244 to move up and down, so as to be inserted into the hole of the material tray 13. Since the holes in adjacent rows on the material tray 13 are staggered, the No. 3 cylinder 243 is set to adjust the position of the syringe along its arrangement direction to ensure that when the next row of syringes is placed, it can be aligned with the holes on the material tray 13.

Preferably, the number of the chain conveying mechanism 21, the conveying channel 22 and the material dividing mechanism 23 are two each, and the clamping mechanism 244 includes a No. 4 cylinder 2441, a first clamping plate 2442 and a second clamping plate 2443. The No. 4 cylinder 2441 drives the first clamping plate 2442 to approach the second clamping plate 2443 to clamp the arranged syringes.

In this embodiment, the two chain conveyor mechanisms 21, the two conveying channels 22 and the two material dividing mechanisms 23 are symmetrically arranged on both sides of the material picking and discharging mechanism 2. The first clamping plate 2442 and the second clamping plate 2443 on the material picking and discharging mechanism 24 are both symmetrical structures, which can simultaneously grab the syringes in the two material dividing mechanisms 23. The syringes can be placed on two material trays 13 at the same time by using one material picking and discharging mechanism 24, which improves efficiency and reduces costs at the same time. The material dividing mechanism 23 is located directly above the chain conveyor mechanism 21, which reduces the movement distance of the material picking and discharging mechanism 24, and only needs to be fine-tuned along the arrangement direction of the syringes through the No. 3 cylinder 243.

The present invention also discloses a method for loading syringes, which uses the above-mentioned syringe loading mechanism to load the syringes into the material box, including the following steps: step 1: the conveying channel 22 continuously conveys the syringes to the material distribution mechanism 23, and the chain transmission mechanism 21 conveys the material tray 13 and positions the material tray 13; step 2: the material distribution mechanism 23 arranges the syringes so that the arranged syringes correspond to the holes in the same row of the material tray 13, and then the material taking and releasing mechanism 24 clamps the arranged syringes; step 3: the material taking and releasing mechanism 24 drives the syringes to move and places the syringes in the holes in the same row of the material tray 13; step 4: repeat the above steps 2 and 3 until all the holes in the material tray 13 are loaded with syringes.

In other words, the material distribution mechanism 23 arranges multiple syringes in a straight line at intervals and aligns them with the holes in the same row on the material tray 13, so that the material placement mechanism 24 can grab the arranged syringes and place them in the material tray 13 at the same time, effectively improving the placement efficiency.
