Description

Robotic arm jig in a system for manufacturing SMC panels for water tanks

The present invention relates to a robot arm jig of an SMC panel manufacturing system for a water tank, and is a technology related to a robot arm jig of an SMC panel manufacturing system for a water tank that can stably seat an SMC material in a press mold by biting it.

The materials used for panel cisterns for water tanks include SMC (Sheet Molding Compound), stainless steel, etc. The SMC panel related to the present invention is a panel formed at high pressure by a hydraulic press using a mold to form a tank body. A raw material reinforced by impregnating glass fibers into a composite mixed with fillers and catalysts in unsaturated polyester resin is put into a mold to form a unit panel having an embossing formed in the center and a flange on the edge. In addition, the unit panel is formed into a square body shape by inserting a sealing gasket into each joint and fastening it with bolts and nuts, and on the outside of the SMC panel, an insulating material having a synthetic resin cover such as polypropylene on the surface of urethane is fastened by a fastening method.

However, in the past, the SMC material had to be moved to a mold in sheet form and then placed into the mold. However, the SMC sheet itself had adhesive properties due to the material mixture, so it often stuck to the clamp when the clamp was released. This caused a problem of delay in the process.

In order to solve the above problem, the present invention provides a robot arm jig of a SMC panel manufacturing system for a water tank, which can use a robot arm to bite and transport a sheet to be a material for an SMC panel so that the sheet does not stick to the SMC material when placed in a mold, thereby enabling a smooth process.

In order to solve the above problem, the present invention provides a system for manufacturing an SMC panel for a water tank, which can be manufactured by moving the first material (M1) and the second material (M2) to a press mold using a robot arm in a loading frame on which a first material (M1) is loaded on an upper loading plate and a second material (M2) is loaded on a lower loading plate, and forming the SMC panel for a water tank, the system comprising: a horizontal frame having a connector connected to the robot arm; an upper fixing unit having a plurality of upper clamps formed on both sides of the horizontal frame to engage or disengage the first material; a lower fixing unit comprising a cylinder installed on a side of the horizontal frame, a plate installed on the cylinder, and a lower clamp installed on the plate to engage or disengage the second material in a tongs-like manner; The present invention provides a robot arm jig for a SMC panel manufacturing system for a water tank, characterized in that the upper clamp and the lower clamp are Teflon-coated to prevent the first and second materials from sticking to the upper clamp and the lower clamp when the first and second materials are released due to non-adhesion, and are placed in a mold.

The above upper fixing unit and lower fixing unit are characterized in that they operate as air units in which the upper and lower clamps are engaged by air pressure.

The above lower fixed unit is characterized in that the cylinder is installed in the bracket so as to protrude laterally from the horizontal frame, and the lower clamp is positioned outside the upper clamp.

The following effects can be expected by the above solution.

Using a robot arm jig, sheets of SMC panel material can be clamped from the top and bottom and transferred to the mold. The clamps are Teflon-coated, preventing the sheets from sticking when released, ensuring a stable fit in the mold. This improves process efficiency.

Furthermore, detailed descriptions of well-known components and functions that may unnecessarily obscure the gist of the present invention will be omitted.

Fig. 2 is a drawing of a loading plate on which a first material and a second material are placed in the robot arm jig of the SMC panel manufacturing system for a water tank according to an embodiment of the present invention.

Referring to FIGS. 1 to 5, the present invention relates to a system for manufacturing SMC panels for water tanks, which can manufacture SMC panels for water tanks by moving the first material (M1) and the second material (M2) from a loading frame (20) in which a first material (M1) is loaded on an upper loading plate (22) in FIGS. 1 and 2 and a second material (M2) is loaded on a lower loading plate (24) to a press mold using a robot arm (10), and forming the SMC panels for water tanks. The system relates to a robot arm jig of the SMC panel manufacturing system for water tanks, and is mainly characterized by a configuration including a horizontal frame (100), an upper fixing unit (200), and a lower fixing unit (300) in FIGS. 3 to 5, and a Teflon coating on the upper clamp (220) and the lower clamp (360). That is, the main point of the present invention is that the surfaces that hold the first material (M1) and the second material (M2) are Teflon coated to prevent the first material (M1) and the second material (M2) that become the SMC panel from sticking together, thereby stably fixing them in the mold.

First, the loading frame (20) is formed in two stages, and the first material (M1) is positioned higher than the second material (M2). The robot arm (10) approaches the loading frame (20) and simultaneously fixes the first material (M1) and the second material (M2), moves to the press mold, releases the fixation of the second material (M2), sets it, and releases the fixation of the first material (M1) and sets it. In the press mold, the second material (M2) and the first material (M1) are combined and become one through high temperature heat and pressure.

The above SMC materials, the first material (M1) and the second material (M2), are a composite of an unsaturated polyester resin mixed with fillers, catalysts, etc. and impregnated with glass fibers. Therefore, the first material (M1) and the second material (M2) are adhesive. To be precise, the first material (M1) is a composite of an unsaturated polyester resin mixed with fillers, catalysts, etc., and is cut into sheets, so it has relatively high adhesiveness. In addition, the second material (M2) is a composite of glass fibers in the form of a non-woven fabric.

In the present invention, the upper clamp (220) and the lower clamp (360) of the upper fixing unit (200) and the lower fixing unit (300) that hold together the first material (M1) and the second material (M2) having such adhesive properties are coated with Teflon, and a very stable compound is formed due to the strong chemical bond between fluorine and carbon of Teflon, thereby providing chemical inertness and heat resistance, non-adhesiveness, excellent insulation stability, low coefficient of friction, etc. The Teflon coating is formed by coating a fluororesin, spraying an appropriate amount on a surface like paint, and then heating and firing at a certain temperature to form an inert, hard coating layer.

The above robot arm has six degrees of freedom and moves along a rail close to or away from the loading frame, and a press mold is located on the side of the rail.

The above horizontal frame (100) is formed in a rectangular shape in the form of a square frame, and is formed with a width and a length that match the sizes of the first material (M1) and the second material (M2). Here, the width may be said to be the width direction and the length may be said to be the length direction. In addition, a connector (120) connected to the end of the robot arm is formed at the center of the horizontal frame (100). Here, the connector (120) is connected in the form of a coupling, and the end of the robot arm is rotatable, so that the horizontal frame (100) can be rotated when connected.

The upper fixing unit (200) is installed in multiple numbers on both sides of the horizontal frame (100), i.e., along the longitudinal direction, to form an upper clamp (220) that engages or releases the first material (M1).

Here, the upper clamp (220) is composed of a horizontally fixed fixed bar (222) and a rotating bar (224) that rotates by the inflow of air. The rotating bar (224) can rotate with respect to the fixed bar (222) to engage or release the SMC sheet.

The lower fixing unit (300) is composed of a cylinder (320) installed on the horizontal frame (100), a plate (340) installed on the cylinder, and a lower clamp (360) installed on the plate (340) to bite or release the second material (M2) in a tongs-like manner. Here, the lower clamp (360) is composed of a horizontally fixed fixed bar (362) and a rotating bar (364) that rotates by the inflow of air. The rotating bar (364) can be rotated with respect to the fixed bar (362) to bite or release.

At this time, the rotating bar (224) of the upper clamp (220) and the fixed bar (222) and the rotating bar (364) of the lower clamp (360) are coated with Teflon.

Therefore, the upper clamp (220) and the lower clamp (360) are characterized by being coated with Teflon so that the first and second materials (M1, M2) do not stick to the upper clamp (220) and the lower clamp (360) when the biting is released due to non-adhesion, and are secured to the mold.

The upper fixed unit (200) and lower fixed unit (300) are characterized in that they operate as air units in which the upper and lower clamps (220, 360) are engaged by air pressure, which is a system for supplying and discharging air.

The lower fixing unit (300) protrudes laterally from the horizontal frame (100) and is characterized in that the cylinder (340) is installed on the bracket (310) and the lower clamp (360) is positioned outside the upper clamp (220).

As described above, it can be seen that the present invention is based on the basic technical idea of a robot arm jig for a SMC panel manufacturing system for a water tank. It is obvious that many other modifications are possible for those skilled in the art within the scope of the basic idea of the present invention.
