The feeding device 70 is arranged at the intersection of the branch rails 332 to ensure that the feeding device 70 can always maintain its own stability when the turntable 30 rotates, so as to cooperate with the workbench 50 and not occupy too much space for placing the feeding material. device 70.

Please refer to FIG. 7 , there are multiple object-carrying belts 73 , and the object-carrying belt 73 includes a belt body 732 and a plurality of positioning cards 734 , and the positioning cards 734 are arranged around the belt body 732 . Adjacent or opposite positioning card platforms 734 between different object belts 73 are in the same plane and together form a positioning area, which is used for placing the printing substrate.

Please refer to Fig. 8, the positioning card table 734 includes a guide block 7341 and a positioning block 7343, one end of the guide block 7341 is connected with the belt body 732, the other end of the guide block 7341 is connected with the positioning block 7343, and the guide block 7341 is close to the belt body 732 One end is farther away from the turntable 30 than the end close to the positioning block 7343, and the plane of the positioning block 7343 is parallel to the plane of the turntable 30, so as to ensure that the position of the printing substrate is not skewed.

Please refer to FIG. 9 , the follow-up track driving rail 35 includes four follow-up track rails 352 , and each follow-up track rail 352 is connected end-to-end in sequence and arranged in a square shape.

The principle of the embodiment of the present invention is:

Place the printed substrate on the feeding device 70. Since the feeding device 70 has a positioning card platform 734, the printed substrate can slide into the area enclosed by the positioning block 7343 under the action of the guide block 7341 of the positioning card platform 734 in the positioning area and realize positioning. .

Thanks to the fact that the carrier belt 73 has multiple positioning card platforms 734 and the feeding device 70 has multiple positioning areas, the feeding device 70 can carry multiple printing substrates. The carrier belt 73 rotates under the drive of the second driving member 75, and the printing substrate gradually moves downward along with the positioning card table 734, and the control unit 90 controls the workbench 50 to stop when it reaches directly below the feeding device 70. At this time, The positioning card table 734 continues to rotate with the belt body 732, and the printing substrate in the positioning area loses the load of the positioning card table 734 and falls into the loading area 53 of the workbench 50. The printing substrate is clamped by the holding portion 51, so far, the loading work is completed.

The number of worktables 50 used in this embodiment is two, and the number of corresponding support rails 332 is also two. The workbench 50 loaded with printed substrates moves to one end of the support rails 332 under the control of the control unit 90 . At this time, the turntable 30 rotates so that the position of the workbench 50 that has completed the loading of the printed substrate corresponds to the printing part 11, and the workbench 50 on the other branch rail 332 advances along the branch rail 332 where it is located, and the same when it advances to the bottom of the feeding device 70 Stop and load the unprinted print substrate. Then under the drive of the track-continuing drive rail 35, the workbench 50 continues to advance. Using the follower drive rail 35 to drive at the intersection of the branch rails 332 can solve the problem that the branch rails 332 cannot continue to drive the workbench 50 well at the intersection.

When the printing unit 11 is working, the newly loaded worktable 50 moves to one end of the rail 332 where it is located, and after the printing work is completed, the turntable 30 rotates. The position of the workbench 50 that has been loaded corresponds to the printing unit 11 , and the position of the workbench 50 that has been printed corresponds to the unloading unit 13 .

Further, the first driving member 55 drives the two clamping arms 512 to move toward the unloading part 13 at the same time, and the two clamping arms 512 can go beyond the loading area 53 of the worktable 50, and push the printed substrate out of the loading area 53. At this time, the clamping arm 512 moves in reverse to release the clamping of the printing substrate.

The printed substrate falls into the unloading part 13. The unloaded part 13 in this embodiment is made into a tank with an inclined surface, and the printed substrate can be separated from the unloaded part 13 under its own gravity. So far, the unloading work is completed.

The workbench 50 after unloading the printing substrate repeats the above steps, so as to realize high-efficiency printing on the printing substrate.

The advantage of using the feeding device 70 is that since the feeding device 70 has a multi-layer positioning area, more printing substrates can be prepared for loading within a certain period of time, which can save some floor space for the printing substrates and is conducive to production. Site facility planning.

In addition, due to the guide block 7341, the printing substrate can be directly placed in the positioning area, and the guide block 7341 can finally guide the printing substrate to the area surrounded by the positioning block 7343 to achieve pre-positioning. Save a certain amount of positioning man-hours, thereby improving the overall production efficiency.

The advantage of setting the clamping arm 512 on the workbench 50 is that it can not only clamp the printing substrate to facilitate printing, but also can complete the unloading work by the movement of the clamping arm 512 itself when the printing substrate of another workbench 50 is being printed. , The work tasks completed in the same period of working hours are more abundant, and the purpose of saving working hours is achieved, thereby improving the overall production efficiency.

An optional solution of the present invention is that when there are multiple branch rails 332, the workbench 50 is made slightly longer in the length direction of the branch rails 332 to ensure that the first driven part 57 can straddle the multiple branch rails 332. The intersection is driven by the branch rails 332, and at the same time, the follow-up drive rails 35 also need to be set according to the number of the branch rails 332 or directly cancel the follow-up drive rails 35, as long as the length of the workbench 50 meets the above requirements.

At this time, the positioning area of the feeding device 70 can be limited, so that the projections of the limiting areas of each layer on the surface of the turntable 30 do not completely overlap, and each positioning area has its own workbench 50 specially corresponding to the printing substrate. With the rotation of the turntable 30 , each branch rail 332 sequentially controls the corresponding worktable 50 to advance to the crossing of the branch rails 332 and load the printing substrate dropped from the corresponding positioning area.

In this way, as long as the time for releasing the printing substrate in the positioning area is calculated, the printing substrate can be dropped just in time when the positioning platform travels to the intersection of the support rails 332, so that the printing substrate can be correctly dropped into the loading area 53 That's it.

In addition, the number of printing parts 11 and the number of unloading parts 13 can be increased according to demand, so that a part of the workbench 50 can be in the working step of receiving printing, and other workbenches 50 can be in the unloading part 13 and perform unloading operations, or complete The unloading material moves toward the end of the support rail 332 where the workbench 50 is located away from the unloading portion 13 , and the printing substrate loading step is completed halfway.

This further improves the production efficiency of printed electronics.

The printed electronic inkjet printer 100 of this embodiment is provided with a turntable 30 on the body 10, and passes through two or more workbenches 50, and the feeding device 70 and the clamping arm 512 of the workbench 50, etc. The cooperation of components can complete more printing work steps in the same period of time, and simplifies and merges certain work actions, so that compared with ordinary inkjet printers, its production of printed electronics is more efficient. Make it possible to realize streamlined operation.

Specifically, the feeding device 210 is a conveyor belt or a mechanical arm. Taking the conveyor belt as an example, the printing substrate is placed on the conveyor belt. When the conveyor belt moves to the top of the feeding device 70, the printing substrate just breaks away from the conveyor belt and falls into the positioning area. Under the action of the guide block 7341, the pre-positioning can be realized, and the following steps can be continued. It is not necessary to position and load the printing substrate to the workbench 50 specially. The robotic arm also only needs to put the printed substrate into the positioning area, without the need for precise delivery.

The transfer device 230 is a conveyor belt or a robot arm. It is preferably a conveyor belt, which is arranged under the unloading part 13. When the printed substrate is unloaded, the printed substrate will slide from the unloading part 13 to the conveyor belt and move with the conveyor belt, thereby facilitating subsequent operations.

The printed electronics production line 200 of this embodiment uses the printed electronic inkjet printer 100 in Embodiment 1, combined with the feeding device 210 and the transfer device 230, to make the production of printed electronics more efficient and reduce the number of personnel operations. Action, which not only saves manpower but also improves the production capacity of printed electronics.
