[0028] A specific embodiment of an automatic reflux film pasting device of the present invention is as follows Figures 1-4 shown:

[0029] An automatic reflux film pasting device includes a feeding mechanism 1, a loading and unloading mechanism 2, a film pasting mechanism 3, a discharging mechanism, and a material transfer mechanism. The material transfer mechanism includes a green material transfer unit and a cooked material transfer unit. Among them, the feeding mechanism 1 includes a film material loading position and a film material transfer unit. The film material is loaded at the film material loading position and transferred through the film material transfer unit. The product is directly loaded at the starting end of the green material transfer unit. The product is transferred between the end of the green material transfer unit and the starting end of the cooked material transfer unit via a detection device. Specifically, the detection device is provided with a mechanical gripper. When the product is transferred to the green material transfer unit, the mechanical gripper grabs the product and is detected by the detection device. After the detection device passes the inspection, the mechanical gripper transfers the material to the cooked material transfer unit. In this application document, the untested product is called green material, and the product that passes the inspection is called cooked material. The transfer direction of the green material transfer unit is opposite to that of the cooked material transfer unit. Among them, the feeding mechanism 1, the green material transfer unit, and the cooked material transfer unit can all be horizontally transferred by a flat belt. The discharging mechanism is docked with the end of the cooked material transfer unit. The discharging mechanism is divided into a passing channel 41 and a temporary storage channel 42 according to the film pasting result of the product. The products with qualified film pasting accuracy enter the passing channel 41 and are transferred to the next workstation, and the products with unqualified film pasting accuracy enter the temporary storage channel 42 for manual discharging.

[0030] The loading and unloading mechanism 2 includes a fixed loading position 21, a movable loading position 22 arranged adjacent to each other, and a transfer component for transferring the material on the movable loading position 22 to the fixed loading position 21. There are two groups of loading and unloading mechanisms 2, and the two groups of loading and unloading mechanisms 2 are respectively located at the transfer end of the green material transfer unit and the starting end of the cooked material transfer unit. The movable loading position 22 of the loading and unloading mechanism 2 located at the green material transfer unit corresponds to the transfer direction of the green material transfer unit, and the fixed loading position 21 of the loading and unloading mechanism 2 located at the cooked material transfer unit corresponds to the transfer direction of the cooked material transfer unit;

[0031] Among them, the transfer component includes a clamping member 23, a clamping cylinder 24 and a translation cylinder 25. There are two clamping members 23. The driving end of the clamping cylinder 24 is connected to the two clamping members 23 and is used to drive the two clamping members 23 to move relative to each other.

The pushing component includes a pushing block and is used to drive the pushing block to move in the direction perpendicular to the reverse direction of the translation cylinder 25 to push the product, so as to achieve precise limiting of the product position.

[0032] The specific operation method of the loading and unloading mechanism 2 is as follows: at the end of the green material conveying unit, the green material conveying direction corresponds to the movable loading position 22. After the green material is conveyed to the movable loading position 22, the clamping cylinder 24 drives the two clamping members 23 to tighten inward to clamp the product. The translation cylinder 25 drives the clamping cylinder 24 to move to transfer the product to the fixed loading position 21. After the products at the fixed loading position 21 and the movable loading position 22 are in place, the mechanical gripper of the detection device simultaneously grabs two juxtaposed products.

[0033] After the products are detected to be qualified, the mechanical gripper grabs two products and places them at the start end of the clinker conveying unit at the same time. The clinker conveying direction corresponds to the fixed loading position 21. After the product at the fixed loading position 21 is conveyed by the clinker conveying unit, the product at the movable loading position 22 is transferred to the fixed loading position 21 under the action of the transfer component and is conveyed by the clinker conveying unit. The loading and unloading mechanism 2 realizes the efficient cooperation operation between the product and the detection device, and improves the processing efficiency of the product.

The driving motor 43 is preferably a stepping motor. The second lifting component 44 includes a lifting cylinder arranged at the bottom of the film pasting position 4. After the product is film-pasted, the lifting cylinder drives the film pasting position 4 to descend to correspond to the unloading mechanism, and separately unloads the qualified and unqualified film-pasted products.

[0035] The film pasting mechanism 3 includes a seat body 33, a film suction plate 34, an angle adjustment component 32, a first lifting component 31 and a linear module component. Among them, the angle adjustment component 32 includes an angle adjustment shaft and a motor for driving the angle adjustment shaft to rotate. The first lifting component 31 is a first lifting cylinder. The film suction plate 34 is arranged at the bottom of the seat body 33.

The first lifting component 31 is slidably assembled with the linear module component. The linear module component is arranged parallel to the upper part of the film material conveying unit. The film suction plate 34 reciprocates between the film material conveying unit and the film pasting position 4 under the action of the linear module to grab and paste the film material.

[0036] A buffer assembly is provided between the seat body 33 and the film suction plate 34. The buffer assembly includes a buffer plate and an elastic buffer member 35. The buffer plate is fixed relative to the bottom of the seat body 33. At least one elastic buffer member 35 is provided between the film suction plate 34 and the buffer plate.

[0037] A CCD assembly is further provided on one side of the film pasting mechanism 3. The CCD assembly is horizontally installed above the film conveying unit through a mounting bracket. After the film pasting mechanism 3 obtains the precise position of the film through the CCD assembly, it drives the linear module to move above the film according to the obtained film position information. Then, it drives the angle adjustment assembly 32 to rotate a specified angle according to the position of the film, and drives the first lifting assembly 31 to descend to suck the film, improving the accuracy of the film suction plate 34 for grasping the film. A re-inspection optical fiber 36 is provided on the seat body 33, and detection holes corresponding to the re-inspection optical fiber 36 are provided on the buffer plate and the film suction plate 34. Among them, small holes are provided on the mobile phone film.
