[0036] The working process of the flipping and clamping mechanism 60 is as follows: the flipping motor 631 drives the flipping motor reducer 632, which drives the synchronous pulley 633, and under the transmission of the synchronous belt 634, drives the flipping shaft 635 and the flipping pressure plate 636 to rotate the flipping pressure plate 636 to a set angle; the front and rear motion motor 6213 drives the front and rear motion lead screw 6212, and under the guidance of the front and rear motion guide rail 6211, drives the motion component 62 and the flipping and clamping component 63 to move on the bottom frame 61 toward the coating workbench 50; when the motion reaches After the upper and lower clamping cylinders 6222 are in position, they move downward, driving the connecting plate 6223 to move downward along the upper and lower guide rails 6224, and the flipping clamping plate 636 is used to clamp the product; when the clamping delay is reached, the upper and lower clamping cylinders 6222 are reset, driving the connecting plate 6223 to move upward along the upper and lower guide rails 6224 for reset; the front and rear motion motor 6213 drives the front and rear motion screw rod 6212, and under the guidance of the front and rear motion guide rails 6211, drives the motion component 62 and the flipping clamping component 63 to reset, thus completing the clamping action.

[0037] In this embodiment, a transparent cover 100 is further provided on the frame 10 to prevent the smell of the glue from affecting the external environment during operation.

[0038] Furthermore, a storage cabinet (not shown in the figure) is also provided on the frame 10 for placing raw material plates and glue, which effectively saves space.

[0039] The working process of the present invention is as follows: 1. Turn on the device, detect the sensor signals of each workstation, and reset each component; 2. The six-axis manipulator first uses the vacuum suction cup part to take out the raw material plate from the U-shaped discharge trough and places it on the coating workbench; 3. The six-axis manipulator moves to the coating workbench, and evenly applies glue on the raw material plate through the glue coating component; 4. The six-axis manipulator moves to the U-shaped discharge trough, takes out another raw material plate and places it on the raw material plate that has been coated with glue, and the flipping and pressing mechanism moves toward the coating workbench and presses down to press the two raw material plates. After the delay arrives, the flipping and pressing mechanism rises and resets; 5. The six-axis manipulator grabs two bonded finished products from the coating workbench and places them in the receiving part.

[0040] Among them, the design of the coating roller is based on the size of the product; the width of the coating roller is slightly narrower than the width of the raw material plate. During coating, the coating component is first moved above the raw material plate, and then the coating component is lowered, and the coating roller contacts the raw material plate. Then the six-axis manipulator moves to drive the coating roller to rotate and apply glue to the surface of the raw material plate. The coating area is slightly smaller than the area of ​​the raw material plate. When the flip pressing plate is pressed down, the glue can just cover the surface of the raw material plate after rolling and exhausting.

[0041] The present invention improves the working environment. Due to the adoption of a sealed glue supply system, the glue in the glue supply barrel will not be emitted into the air. In addition, there is a sealed transparent cover to avoid the influence of the smell of glue on the external environment during work. Due to the adoption of a six-axis manipulator to apply glue, the coating process of the six-axis manipulator is very precise and accurate, and the operation is stable, which can ensure that the glue applied to each product is uniform. Due to the adoption of a glue supply mechanism to supply glue, the amount of glue added to each product is accurate and stable, ensuring that the amount of glue is accurate and stable. The strength and speed of the six-axis manipulator's brushing roller are both program-controlled, and can work stably for a long time, ensuring that the glue film thickness is uniform and stable. The device can work uninterruptedly for a long time, does not require employee participation during the working process, and only needs to load and unload materials at regular intervals, thereby reducing the labor intensity of employees, improving production efficiency and cost, and having strong practicality.

[0042] The above examples are only used to further illustrate the technical content of the present invention, so that readers can understand it more easily, but they do not mean that the implementation of the present invention is limited to this.
