[0045] As Figures 1-11 shown, an automatic film pasting device for electronic components in this embodiment includes a frame 1, a conveying mechanism 2, a film feeding mechanism 3 and a product feeding mechanism 4 are arranged on the frame 1. The product feeding mechanism 4 is located on the right side of the film feeding mechanism 3. The film feeding mechanism 3 is used to realize the feeding of the cut film. The product feeding mechanism 4 is used to automatically convey the product. The conveying mechanism 2 is used to convey the cut film to the product for film pasting. The product after film pasting is then conveyed to the next process through the product feeding mechanism 4;

[0046] The film feeding mechanism 3 includes a film unwinding reel 31, a first adsorption table 32, a second adsorption table 33, a shearing table 34, a film winding reel 35, and a plurality of guide rollers 36. The film unwinding reel 31, the first adsorption table 32, the second adsorption table 33, and the shearing table 34 are arranged in sequence from left to right. Both the film unwinding reel 31 and the film winding reel 35 are connected to a driving source 37. A shearing system is provided on the shearing table 34, and the shearing system can be a shearing knife driven by a moving cylinder. During operation, the film roll is placed on the film unwinding reel 31, and the driving source 37 is used to rotate the film unwinding reel 31 and the film winding reel 35, so that the film roll on the film unwinding reel 31 unwinds. The released film is sequentially conveyed to the upper surfaces of the first adsorption table 32, the second adsorption table 33, and the shearing table 34. Here, the film is actually composed of an attachment layer and a separation layer. When the film is on the first adsorption table 32 and the second adsorption table 33, the attachment layer and the separation layer are not separated. When the film is conveyed from the second adsorption table 33 to the shearing table 34, the attachment layer and the separation layer are separated, so that the attachment layer adheres to the upper surface of the shearing table 34 and moves, while the separation layer passes through the gap between the second adsorption table 33 and the shearing table 34, bypasses the winding roller, and is wound on the film winding reel 35. Through the rotation of the winding roller, the winding of the separation layer is realized. When the conveying distance of the attachment layer on the shearing table 34 reaches the set length, the film unwinding stops. The film is adsorbed and fixed through the adsorption holes on the first adsorption table 32 and the second adsorption table 33, and then the attachment layer on the shearing table 34 is cut by the shearing system. The cut attachment layer is conveyed to the product feeding mechanism 4 by the conveying mechanism 2 to realize the feeding of the attachment layer. Subsequently, the film unwinding continues to realize the sequential cutting of the attachment layer, that is, the feeding of the attachment layer;

[0047] A pressing device 38 is provided on the first adsorption table 32. During the shearing process of the attachment layer, the film is pressed tightly on the first adsorption table 32 by the pressing device 38 to improve the shearing stability;

[0048] The product feeding mechanism 4 includes an intermediate material conveying assembly 41 and two end material conveying assemblies 42. The two end material conveying assemblies 42 are respectively located at the front and rear ends of the intermediate material conveying assembly 41;

[0049] The end material conveying assembly 42 includes a first material conveying frame 421. A first material conveying belt 422 is provided on the first material conveying frame 421, and the first material conveying belt 422 is driven to move by a first material conveying power system 423;

[0050] The intermediate material conveying assembly 41 includes a second material conveying frame 411. A second material conveying belt 412 is provided on the second material conveying frame 411, and the second material conveying belt 412 is driven to move by a second material conveying power system 413;

[0051] During operation, the front end material conveying assembly 42 is used to receive the incoming products. The incoming products are automatically conveyed by the conveying system of the previous process. The rear end material conveying assembly 42 is used to automatically convey the products after film sticking to the next process;

[0052] When the incoming product enters the front-end feeding component 42, the incoming product is conveyed onto the first conveyor belt 422. By driving the first conveyor belt 422 with the first conveying power system 423, the first conveyor belt 422 conveys the incoming product onto the second conveyor belt 412 and applies a film thereto.

[0053] After the product on the second conveyor belt 412 is completely film-applied, the second conveyor belt 412 is driven to move by the second conveying power system 413, that is, the product on the second conveyor belt 412 is driven to move to the rear-end feeding component 42.

[0054] The product after film application is conveyed onto the first conveyor belt 422 in the rear-end feeding component 42. By driving the first conveyor belt 422 with the first conveying power system 423, the first conveyor belt 422 conveys the product after film application to the next process.

[0055] A positioning unit 414 is provided on the second conveying frame 411. The positioning unit 414 includes a positioning block 4141 and a positioning cylinder 4142. The positioning cylinder 4142 is used to drive the positioning block 4141 to move up and down. The cylinder body of the positioning cylinder 4142 is fixedly arranged on the second conveying frame 411. When the incoming product is conveyed onto the second conveyor belt 412, the rear side of the product abuts against the positioning block 4141. In this way, the positioning of the product on the second conveyor belt 412 is realized. After the product is completely film-applied, the positioning block 4141 is driven to descend by the positioning cylinder 4142, so that the positioning block 4141 is separated from the product, enabling the product to be normally conveyed backward. By positioning the product, the film application accuracy of the product is improved.

[0056] There are two first conveyor belts 422, which are distributed front and rear. There are two groups of second conveyor belts 412, and the two groups of second conveyor belts 412 correspond to the two first conveyor belts 422 one by one. A gap is provided between the two second conveyor belts 412 in the same group.

[0057] The second conveying frame 411 includes a screw 4111, a fixed part 4112 and two moving parts 4113. The two moving parts 4113 are respectively located on the left and right sides of the fixed part 4112, and the two moving parts 4113 correspond to the two groups of second conveyor belts 412 one by one. The second conveyor belt 412 is located between the moving part 4113 and the fixed part 4112. There are two second conveyor belts 412 in each group, and the two second conveyor belts in the same group are respectively connected to the fixed part 4112 and the moving part 4113. The screw 4111 is parallel to the left-right direction. The screw 4111 is rotatably connected to the fixed part 4112, and both moving parts 4113 are threadedly connected to the screw 4111. The thread rotation directions of the two moving parts 4113 with respect to the screw 4111 are opposite.

[0058] When it is necessary to adjust the distance between the fixed part 4112 and the moving part 4113 according to the product size, rotate the screw 4111 to make the two moving parts 4113 approach or move away from each other by a set distance;

[0059] The conveying mechanism 2 includes a suction nozzle 21 and a conveying component 22, and the conveying component 22 is used to realize the up-and-down, left-and-right, and front-and-back movement of the suction cup;

[0060] The conveying mechanism 2 further includes a nozzle 23, and the nozzle 23 is connected to the conveying component 22;

[0061] The conveying component 22 includes a front-and-back movement module 221, a left-and-right movement module 222, and an up-and-down movement module 223. The left-and-right movement module 222 is arranged on the movable part of the front-and-back movement module 221, the up-and-down movement module 223 is arranged on the movable part of the left-and-right movement module 222, and both the suction nozzle 21 and the nozzle 23 are connected to the movable part of the up-and-down movement module 223;

[0062] During operation, the suction nozzle 21 and the nozzle 23 are driven to move by the conveying component 22. The cut attachment layer is adsorbed by the suction nozzle 21, and the attachment layer is attached to the product by the movement of the suction nozzle 21. Before the suction nozzle 21 adsorbs the cut attachment layer and before attaching the cut attachment layer to the product, the attachment layer and the product are blown by the nozzle 23 respectively, and dust removal is achieved under the action of the air flow to avoid the influence of dust on the adsorption and film pasting effects;

[0063] Three groups of detection mechanisms 5 are further arranged on the frame 1. The three groups of detection mechanisms 5 correspond to the first adsorption table 32, the shearing table 34, and the second material conveying rack 411 respectively. Appearance detection is realized through the three groups of detection mechanisms 5 respectively after the film is conveyed to the first adsorption table 32, after the adsorption layer is sheared, and after the product is film pasted. Each group of detection mechanisms 5 is provided with two, and the two detection mechanisms 5 in the same group are distributed vertically;

[0065] Two film feeding mechanisms 3 are provided, and the two film feeding mechanisms 3 are symmetrically distributed front and back. In this way, double-station feeding of the film is realized, and the efficiency is improved;

[0066] In summary, through the automatic conveying of the product and the attachment layer, automatic film pasting is realized, reducing the labor intensity of workers. Moreover, during film pasting, by realizing the positioning of the product, the film pasting accuracy is improved. In addition, by removing dust from the attachment layer and the product, the adsorption and film pasting effects are enhanced.
