Figure 4 It is another structural schematic diagram of the present invention; Figure 5 It is a schematic structural diagram of the feeding device of the present invention; Figure 6 For the present invention Figure 4 The enlarged schematic diagram of the structure at A in the middle. The feeding device 1 includes a feeding mechanism 11 and a first conveying mechanism 12. The feeding mechanism 11 conveys the screen to be inspected. The first conveying mechanism 12 is arranged on one side of the feeding mechanism 11 and conveys the feeding mechanism 11 to the screen at one end for adsorption and conveyance.

[0024] The feeding mechanism 11 includes a feeding conveying assembly 111 and a feeding limiting assembly 112. The feeding conveying assembly 111 includes a feeding driving member 1111 and a feeding conveying member 1112. The feeding conveying member 1112 is connected to the driving end of the feeding driving member 1111, and the feeding driving member 1111 drives the feeding conveying member 1112 to convey the display screen 100. The feeding limiting assembly 112 includes a feeding limiting driving member 1121 and a feeding limiting member 1122. 21 is connected to one end of the loading conveyor 1112, the loading limit member 1122 is connected to the driving end of the loading limit driving member 1121, and is located on one side of the transmission path of the loading conveyor 1112, the loading limit driving member 1121 drives the loading limit driving member 1121 to apply a thrust to the display screen 100 transmitted on the loading conveyor 1112, so that the display screen 100 is located at the same position on the loading conveyor 1112, thereby achieving the effect of limiting the display screen 100.

[0025] Specifically, the loading conveyor 1112 is a conveyor belt, and the loading is automatically performed through other equipment (not shown in the figure).

[0026] The first transport mechanism 12 includes a first driving assembly 121 and a first transport assembly 122. The first driving assembly 121 includes a first driving member 1211 and a first guiding member 1212. The first driving member 1211 is disposed on one side of the loading conveyor member 1112. The first guiding member 1212 is connected to one end of the first driving member 1211. The first transport assembly 122 includes a first transport driving member 1221, a first transport guiding member 1222 and a first transport robot 1223. The first transport driving member 1221 is connected to the driving end of the first driving member 1211 and is moved along the conveyor. The first guide member 1212 moves in the guiding direction, the first transport guide member 1222 is connected to one end of the first transport drive member 1221, the first transport robot 1223 is connected to the drive end of the first transport drive member 1221, and the first transport robot 1223 moves along the guiding direction of the first transport guide member 1222. Through the cooperation of the first drive member 1211 and the first transport drive member 1221, the first transport robot 1223 can have the ability to move in two directions, so that the first transport robot 1223 can move up, down or move horizontally.

[0027] One end of the first transport robot 1223 is provided with a suction fixture, so that the display screen 100 can be attracted by negative pressure adsorption, and the display screen 100 can be transported in cooperation with the first driving member 1211 and the first transport driving member 1221 .

[0028] The first transport component 122 also includes a first rotating drive member 1224, which is arranged between the driving end of the first transport drive member 1221 and the first transport robot 1223, and the first rotating drive member 1224 can drive the first transport robot 1223 to rotate 360 ​​degrees, so that after the first transport robot 1223 completes the adsorption of the display screen 100, the first transport robot 1223 can be driven to rotate by the first rotating drive member 1224, so that no matter whether the display screen 100 on the loading conveyor 1112 is in a state of facing up with its surface or facing up with its back, the first transport robot 1223 can flip the display screen 100 to the designated surface for transport.

[0029] Specifically, whether the first rotating driving member 1224 rotates is controlled according to the front and back states of the loaded product.

[0030] Reference Figure 7-Figure 11 , Figure 7 It is a schematic structural diagram of the surface detection device of the present invention; Figure 8 Another structural schematic diagram of the surface detection device of the present invention; Fig. 9 It is a schematic diagram of the structure of the surface detection platform of the present invention; Fig.10 It is a schematic diagram of the structure of the film tearing mechanism of the present invention; Fig.11 For the present invention Fig.10The surface detection device 2 includes a surface detection platform 21, a film-tearing mechanism 22 and a surface detection mechanism 23. The surface detection platform 21 includes a surface bearing component 211 and a surface driving component 212. The surface bearing component 211 is arranged on the moving path of 2123. The surface bearing component 211 carries the display screen 100. The surface driving component 212 is connected to the surface bearing component 211, and the surface driving component 212 drives the surface bearing component 211 to move, so that after the display screen 100 is placed on the surface bearing component 211, the surface driving component 212 can drive the surface bearing component 211 to move, thereby driving the display screen 100 to move synchronously; the film-tearing mechanism 22 includes a film-tearing driving component 222 and a film-tearing component 223. The film-tearing driving component 222 is arranged on the moving path of 2123. The film tearing assembly 223 is placed on the moving path of the surface bearing component 211, and is connected to the driving end of the film tearing driving assembly 222, and clamps the tearing hand position 201 of the screen film 200, and peels off the screen film 200, so that after the tearing hand position 201 is clamped by the film tearing assembly 223, the film tearing driving assembly 222 drives the film tearing assembly 223 to gradually move away from the display screen 100, so that the screen film 200 is gradually peeled off toward the other end along the portion where the tearing hand position 201 is set; and the surface detection mechanism 23 is set on the moving path of the surface bearing component 211, and detects the position of the display screen 100 where the screen film 200 is peeled off, and identifies scratches, defects, etc. on the surface of the display screen 100 by taking pictures, so as to screen out defective or good products in the display screen 100.

[0031] The screen surface detection device is provided with a film-tearing mechanism 22 between a surface detection platform 21 and a surface detection mechanism 23, so that when the display screen 100 is moved toward the surface detection mechanism 23 through the surface detection platform 21 carrying belt detection, and when it moves to the position of the film-tearing mechanism 22, the film-tearing assembly 223 clamps the tearing hand position 201 of the screen film 200, and the film-tearing driving assembly 222 drives the film-tearing assembly 223 to move, thereby gradually peeling off the screen film 200, so that the surface detection mechanism 23 can directly detect the screen, thereby avoiding the situation that the traditional screen detection device applies the film after the detection, resulting in the screen being easily scratched, stained or flawed after the detection and before the film is applied.

[0032] The film tearing mechanism 22 also includes a pressure wheel assembly 221, which is arranged on the moving path of the surface bearing assembly 211 and applies pressure to the screen. The pressure wheel assembly 221 applies pressure to the screen film 200 toward the display screen 100 before the film tearing driving assembly 222, thereby ensuring that the screen film 200 is in contact with the display screen 100 at the pressure-applying portion of the pressure wheel assembly 221, while the film tearing driving assembly 222 can only uncover the unpressurized portion near the tearing hand position 201.

[0033] The pressure wheel assembly 221 includes a pressure wheel driving component 2211 and a pressure wheel component 2212. The pressure wheel driving component 2211 is arranged on the moving path of the surface bearing component 211. The pressure wheel component 2212 is connected to the driving end of the pressure wheel driving component 2211 and is located on the side of the pressure wheel driving component 2211 close to the surface bearing component 211. Under normal circumstances, the pressure wheel component 2212 is located close to the pressure wheel driving component 2211, so that the surface bearing component 211 has enough space to drive the display screen 100 to move. After the surface bearing component 211 drives the display screen 100 to move to the specified position, the pressure wheel driving component 2211 drives the pressure wheel component 2212 to move in the direction close to the display screen 100, so that the pressure wheel component 2212 contacts the screen film 200 and applies pressure to it in the direction of the display screen 100.

[0034] Specifically, the pressure wheel driving component 2211 is a cylinder, and the pressure wheel component 2212 is cylindrical, and the outer side is made of flexible material, so that under the action of the pressure wheel driving component 2211, when the pressure wheel component 2212 contacts the screen film 200, it will only apply a linear pressure to the screen film 200, and as the surface bearing component 211 drives the display screen 100 to move, the pressure wheel component 2212 rotates to change the position of the display screen 100 that is subjected to force.

[0035] The screen surface detection device is provided with a pressure wheel assembly 221, so that before the film tearing assembly 223 clamps the tearing hand position 201 of the screen film 200 and peels off the screen film 200, the pressure wheel assembly 221 can first apply pressure to the screen film 200 in the direction of the display screen 100, so that the film tearing assembly 223 can only peel off the screen film 200 beyond the pressure wheel assembly 221, avoiding the screen film 200 being completely peeled off, resulting in difficulty in sticking it back, and after completing the screen detection, the surface detection platform 21 drives the display screen 100 to move in the reverse direction, so that under the pressure of the pressure wheel assembly 221, the film tearing assembly 223 moves in the reverse direction, and the screen film 200 is gradually and automatically stuck back to the surface of the display screen 100, further ensuring the stability of the film tearing mechanism 22 in peeling off the screen film 200, and can automatically stick the screen film 200 back.

[0036] The film tearing assembly 223 includes a film tearing driving member 2231 and a film tearing clamp 2232. The film tearing driving member 2231 is connected to the driving end of the film tearing driving member 222, so that the film tearing driving member 222 can drive the film tearing driving member 2231 to move. The film tearing clamp 2232 is connected to the driving end of the film tearing driving member 2231, and the film tearing clamp 2232 clamps the tearing hand position 201 of the screen film 200 and uncovers the screen film 200, and drives the display screen 100 on the surface bearing assembly 211. After moving to the specified position, the film tearing driving component 222 first drives the film tearing driving part 2231 to move towards the tearing hand position 201, and one end of the film tearing clamp 2232 is located below the tearing hand position 201, and then the film tearing driving part 2231 drives the other end of the film tearing clamp 2232 to move to clamp the tearing hand position 201, and then the film tearing driving component 222 is used to mobilize the film tearing driving part 2231 to move away from the display screen 100, thereby peeling off the screen film 200.

[0037] The surface bearing assembly 211 includes a surface bearing member 2111 and a surface adsorption member 2112. The surface bearing member 2111 bears the display screen 100. The surface adsorption member 2112 is connected to the surface bearing member 2111 and adsorbs the display screen 100 carried by the surface bearing member 2111. The surface adsorption member 2112 applies suction to the display screen 100, thereby ensuring that the display screen 100 is always in a state of close contact with the surface bearing member 2111, ensuring that the position of the display screen 100 will not shift when subjected to the pressure of the pressure wheel member 2212 and the pulling force of the film tearing clamp 2232, thereby ensuring the stability of detection.

[0038] The surface driving component 212 includes a surface driving member 2121 and a surface guiding member 2122 . The surface driving member 2121 is connected to the surface bearing member 2111 . The surface guiding member 2122 is disposed on one side of the driving end of the surface driving member 2121 , and the surface guiding member 2122 guides the movement of the surface bearing component 211 .

The surface detection bracket 231 is disposed on the moving path of the surface bearing member 2111 . The surface detection assembly 232 is connected to the surface detection bracket 231 and detects the surface of the display screen 100 .

[0040] The surface detection component 232 includes a surface detection component 2321 and a surface lighting component 2322. The surface detection component 2321 is connected to the surface detection bracket 231, and the surface detection component 2321 takes a photo of the display screen 100 for detection. The surface lighting component 2322 is connected to the surface detection bracket 231, and the surface lighting component 2322 illuminates the display screen 100. The display screen 100 is first illuminated by the surface lighting component 2322 to make scratches, flaws, etc. appear, and then the display screen 100 is photographed by the surface detection component 2321 to distinguish defective products from good products by comparison.
