[0028] It is understandable that, referring to Figures 1 to 6 The embodiment of the present invention provides an automated film removal and screening device, including a machine 100, a film removal component 200, a detection component 300, a rejection component 400 and a controller. The machine 100 is provided with a conveyor belt component 110 to convey a digital display module 500. The film removal component 200 includes a bracket 210, a film removal roller 220 and a film separation sheet 230. The bracket 210 is fixed to the machine 100, and the film removal roller 220 is rotatably connected to the bracket 210. , and is located above the conveyor belt assembly 110. The surface of the film removal roller 220 is sticky, that is, the adhesive force of the film removal roller 220 on the auxiliary film 510 is greater than the adhesive force of the auxiliary film 510 on the digital display module 500. An annular groove 221 is provided in the middle of the film removal roller 220. One end of the film separation sheet 230 is provided in the annular groove 221. The film separation sheet 230 is arranged obliquely in the annular groove 221, and the film separation sheet 230 is lower than the highest point of the film removal roller 220. Figure 2As shown, when the film removal roller 220 drives the auxiliary film 510 to rotate, the auxiliary film 510 will inevitably contact the film separation sheet 230, and the other end of the film separation sheet 230 extends to the outside of the annular groove 221, and the auxiliary film 510 is lifted up by the film separation sheet 230, so that the auxiliary film 510 is separated from the film removal roller 220; the detection component 300 includes a machine cover 310 and a camera 320, the machine cover 310 is arranged above the conveyor belt assembly 110, the machine cover 310 is provided with a vertically through detection channel 311, the machine cover 310 is provided with a light source, and the camera 320 is provided inside the machine cover 310. 0 is located above the detection channel 311; the rejection component 400 is connected to the machine 100, and the rejection component 400 includes a lifting component 410, a rotating component 420 and a vacuum suction nozzle 430. The vacuum suction nozzle 430 can be connected to a vacuum pump or a strong exhaust fan through an air pipe. The rotating component 420 is connected to the output end of the lifting component 410, and the vacuum suction nozzle 430 is connected to the output end of the rotating component 420; the conveyor belt component 110, the film removal component 200, the detection component 300 and the rejection component 400 are all electrically connected to the controller.

[0029] The use process of the automatic film removal and screening device is as follows: after the digital display module 500 is filmed, it is placed on the conveyor belt assembly 110 for transportation. The digital display module 500 first passes through the film removal assembly 200, and the adhesive film removal roller 220 contacts the digital display module 500 to take away the auxiliary film 510. Then the auxiliary film 510 is lifted up by the film separation sheet 230 and separated from the film removal roller 220, so that the film removal roller 220 can continuously take away the auxiliary films 510 on multiple digital display modules 500; then the digital display module 500 passes through the detection assembly 300, and the digital display module 500 stays under the detection channel 311. Under the illumination of the light source, the camera 320 can take a clear image, and then judge according to the image. The controller determines whether the film removal is complete; based on the information fed back by the detection component 300, if there is a digital display module 500 that has not been film-removed, it controls the rejection component 400 to start, and the rotating component 420 drives the vacuum suction nozzle 430 to rotate to the top of the conveyor belt component 110. The lifting component 410 drives the rotating component 420 and the vacuum suction nozzle 430 to descend, and uses the vacuum suction nozzle 430 to suck the digital display module 500 that has not been film-removed. The lifting component 410 then drives the rotating component 420 and the vacuum suction nozzle 430 to rise. The rotating component 420 drives the vacuum suction nozzle 430 and the digital display module 500 to rotate outside the conveyor belt component 110. The vacuum suction nozzle 430 cancels the suction force, and the digital display module 500 falls and is collected. The digital display module 500 after film removal is sent by the conveyor belt component 110 to the equipment of the next process. The film removal, detection and rejection of unqualified products are fully automated, improving work efficiency, reducing manpower and time costs, eliminating errors and omissions caused by manual operation, and improving the final product quality.

[0030] It is understood that in some embodiments of the present invention, the angle between the separator 230 and the horizontal direction is at least 45 degrees. When the auxiliary film 510 is separated from the film removal roller 220, the auxiliary film 510 will be attached to the separator 230. Since the separator 230 has a large inclination angle, the auxiliary film 510 can be separated from the separator 230 and fall off due to the weight of the auxiliary film 510. Moreover, when multiple auxiliary films 510 are piled up, the weight is greater and the falling speed is faster. Figure 3 The diaphragm 230 is fixed to the bracket 210 by screws. The bracket 210 has a vertical mounting slot, and the position of the screws can be adjusted to fine-tune the height of the diaphragm 230.

[0031] Furthermore, the film removal assembly 200 also includes a first conveyor slide 240. The first conveyor slide 240 is arranged at an angle, with the upper end of the first conveyor slide 240 located below the film separation sheet 230. The angle between the first conveyor slide 240 and the horizontal direction is at least 15 degrees. After the auxiliary film 510 separates from the film removal roller 220, it falls onto the first conveyor slide 240 and slides down the first conveyor slide 240 for easy collection. A film collection box 120 can be placed on the machine 100, and the lower end of the first conveyor slide 240 extends into the inner cavity of the film collection box 120. All auxiliary films 510 slide into the film collection box 120 for easy collection and post-processing.

[0032] It is understandable that the lifting component 410 of the rejection assembly 400 can be made of a cylinder, an electric push rod, a linear motion module, etc., and the rotating component 420 can be made of a rotating cylinder, a motor, etc., all of which can meet the use requirements.

[0033] Reference Figure 1 and Figure 2 In some embodiments of the present invention, a defective product collection box 130 is placed on the machine 100, and a second conveying slide 140 arranged obliquely is connected to the machine 100. The lower end of the second conveying slide 140 extends to the inner cavity of the defective product collection box 130, and the vacuum suction nozzle 430 can be moved to the top of the second conveying slide 140. After the rejection component 400 transfers the digital display module 500 without film removal, the digital display module 500 falls on the second conveying slide 140, and slides through the second conveying slide 140 to the defective product collection box 130 for collection, which is convenient for unified processing.

[0034] It can be understood that in order to adjust the angle of the second conveying slide 140, a horizontal optical axis 141 can be set on the machine 100, and a clamping block 142 is provided on the bottom surface of the second conveying slide 140. The clamping block 142 is provided with an open groove for accommodating the optical axis 141 and is locked to the optical axis 141 by a fastener. The fastener can be a bolt. The angle of the second conveying slide 140 can be adjusted by loosening the bolt. It can adapt to auxiliary films 510 of various specifications to expand the scope of use.

[0035] In some embodiments of the present invention, the detection component 300 is also provided with a bottom light source 330. The bottom light source 330 is arranged below the conveyor belt component 110 and is located directly below the detection channel 311. The bottom light source 330 has a large area and can illuminate the entire space where the hood 310 is located, thereby increasing the brightness, helping to capture clear images, and helping to distinguish the digital display module 500 that has not been removed from the film.

[0036] Reference Figure 5 and Figure 6 In some embodiments of the present invention, the conveyor belt assembly 110 includes two symmetrically arranged conveyor bases 111. Each conveyor base 111 is provided with pulleys 112 at both ends, and a belt 113 is connected to the two pulleys 112. At least one pulley 113 is connected to a drive element to achieve rotation. The drive element can be a servo motor, a stepper motor, etc. A guardrail 114 is provided on the upper end surface of the conveyor base 111. The guardrail 114 is higher than the highest point of the belt 113, and the two guardrails 114 are distributed on the outside of the two belts 113. The digital display module 500 is transported on the two belts 113. The two guardrails 114 limit the digital display module 500 to prevent it from deviating or falling. In addition, the gap between the two belts 113 allows light from the bottom light source 330 to pass through, facilitating the illumination of the digital display module 500.

[0037] Furthermore, a slide rail 115 is provided on the machine 100, and a slider 116 is provided on the bottom surface of the conveyor base 111. The slider 116 is slidably connected to the slide rail 115. By moving the slider 116 on the slide rail 115, the distance between the two belts 113 can be adjusted to adapt to digital display modules 500 of different sizes, expand the scope of use, and improve versatility. Furthermore, a positioning frame 117 is provided on the machine 100, and the positioning frame 117 is provided with a positioning groove. The conveyor base 111 is provided with a positioning block, and the positioning block is connected with a locking bolt. The locking bolt is passed through the positioning groove of the positioning frame 117, thereby fixing the position of the conveyor base 111. When adjustment is required, the bolt can be loosened, and the operation is simple. In addition, an electric adjustment mechanism can also be used, such as an electric push rod, a motor-driven linear module, etc.

[0038] In addition, considering that the two ends of the conveyor belt assembly 110 are cylindrical pulleys 112, there will be a certain gap between the two conveyor belt assemblies 110, which is not conducive to conveying the digital display module 500 with a shorter length. An auxiliary connecting piece can be provided, and the auxiliary connecting piece is fixed to the conveyor base 111. Multiple rollers are provided on the auxiliary connecting piece. The rollers are at the same height as the belt 113, which can support the digital display module 500 and prevent the digital display module 500 from shifting or falling.

[0039] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
