[0047] Specifically, based on the positions of the first screen and the second screen on the first supporting portion detected by the detection component 300, and based on the expected positions of the first screen and the second screen on the second supporting portion, the first compensation component 410 performs compensation adjustment on the first suction cup component 420 in the X-direction position and / or the Y-direction position and / or the first angle, and the second compensation component 410 performs compensation adjustment on the second suction cup component in the X-direction position and / or the Y-direction position and / or the second angle, so that the first suction cup component 420 and the second suction cup component correctly place the first screen and the second screen on the second supporting portion. The first suction cup component can adsorb the first screen or the second screen, and the second suction cup component can adsorb the second screen or the first screen, and the first suction cup component and the second suction cup component jointly complete the adsorption of the first screen and the second screen.

[0050] Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, a fixed suction nozzle is located at the center of the first suction cup component 420, which contacts the screen. To facilitate suction of screens of different sizes, the first suction cup component 420 is adjustable. Specifically, the first suction cup component 420 includes a first adjustment member 421 and a second adjustment member 422. The second adjustment member has multiple suction nozzles, and the fixed suction nozzle and multiple suction nozzles work together to absorb the screen.

[0051] Specifically, there is one first adjustment member 421 and two second adjustment members 422. A mounting hole 421a is provided in the middle of the first adjustment member 421. The fixed suction nozzle is installed in the mounting hole 421a to adsorb the middle of the screen body. The first adjusting member 421 is provided with a first bar hole 421b on both sides, and the mounting hole 421a is located between the two first bar holes 421b. A first slider 422a is provided in the middle of the second adjusting member 422, and the first slider 422a is installed in the first bar hole 421b and can slide adjustably along the first bar hole 421a. The sliding adjustment of the two first sliders 422a can change the distance between the two second adjusting members 422 to adapt to screens of different lengths; the second adjusting member 422 is provided with a second bar hole 422b on both sides, and a plurality of second sliders 423 are installed in the second bar holes 422b. The suction nozzle 420a is installed on the second slider 423, and the second slider 423 can slide along the second bar hole 422b. Adjusting the distance between the two second sliders 423 can change the distance between the two suction nozzles. Accordingly, the distance between the multiple suction nozzles is adjustable, which can adapt to screens of different widths and can also more securely adsorb the screen. Likewise, the structure of the second suction cup component is the same as that of the first suction cup component 420 , and the second suction cup component can adapt to the adsorption of screens of different lengths and widths.

[0052] The cleaning assembly 500 is arranged around the first turntable 100. The first turntable 100 rotates, driving the first bearing portion 110 to rotate and pass through the detection assembly 300, the transport assembly 400, and the cleaning assembly 500 in sequence. The cleaning assembly 500 includes a cleaning bracket 510, a cleaning roller 520, a cleaning member, a carrier 540, a driving roller 550, a tensioning roller 560, and a winding roller 570. A cleaning guide rail 511 is provided on the inner side of the top of the cleaning bracket 510. A cleaning mounting frame 512 is mounted on the cleaning guide rail 511 via a slider. The cleaning mounting frame 512 moves forward and backward relative to the cleaning guide rail 511. The cleaning roller 520 is mounted on the cleaning mounting frame 512 via a lifting portion 513. The cleaning roller 520 moves up and down relative to the cleaning mounting frame 512. As a result, the cleaning roller 520 can move in the lifting direction and can also move in the forward and backward direction. The cleaning roller 520 can move out of the cleaning bracket 510 and descend or not to contact the first carrying portion 110 to clean the first carrying portion 110 .

[0053] A carrier 540 is provided inside the cleaning bracket 510, and limiting members 541 are provided on both sides of the carrier 540. The two limiting members 541 are used to limit the cleaning member, which can be cleaning paper, cleaning cloth, etc. One side of the cleaning member is wound on the active roller 550, bypassing the tensioning roller 560 and the carrier 540, and the other side of the cleaning member is wound on the winding roller 570. The cleaning member is laid on the carrier 512, and the two limiting members 541 on both sides limit the cleaning member. When the cleaning roller 520 moves, it contacts the cleaning member that is partially covered on the carrier 540 to remove dust, particles, etc. on the cleaning roller 520. The cleaning roller 520 moves forward away from the cleaning bracket 510, then descends to contact the first bearing part 110, and then the cleaning roller 520 moves backward close to the cleaning bracket 510 to clean the first bearing part 110. After the first supporting portion 110 is cleaned, the cleaning roller 520 picks up dust, particles, cutting chips, etc. on the first supporting portion 110, such as particles and cutting chips on the screen after cutting. The first supporting portion then starts to support the screen again. The cleaning roller 520 moves closer to the carrier 540 and contacts the cleaning member on the carrier 540. Dust, particles, etc. on the cleaning roller 520 adhere to the cleaning member. The active roller 550 rolls, causing the cleaning member to move. The limiting member 541 limits the movement of the cleaning member. The cleaning member is then reeled in by the reeling roller 570. The cleaning member picks up dust, particles, cutting chips, etc. on the cleaning roller, thereby cleaning the cleaning roller 520. Therefore, the cleaning assembly can clean the first supporting portion and also clean itself.

[0054] The inspection assembly 300, the transport assembly 400, and the cleaning assembly 500 are arranged around the first turntable 100. When the first turntable 100 rotates, the multiple screens on the first support portion 110 pass through the inspection assembly 300 and arrive at the second turntable 200. The transport assembly then transports the multiple screens from the first support portion to the second turntable. The inspection assembly 300 and the transport assembly 400 are arranged at a 90-degree angle. This 90-degree angle has advantages. First, it facilitates the alignment of the multiple screens. Second, it facilitates the position adjustment and adsorption of the screens by the first suction cup component 420. The transport assembly 400 can move between the first support portion 110 and the second support portion 210 to transport the multiple screens. After the transport assembly 400 correctly places the multiple screens on the second support portion, the screens pass through the film stripping station, the screen corner cutting station, and the AOI inspection station in sequence to strip the screen film, cut the screen corners, and perform AOI inspection on the screens, thus completing the screen processing.

[0059] Step S102: The suction cup of the robot picks up the multiple screens and places them on the first turntable. Specifically, the suction cup of the robot picks up the multiple screens and places them on the first supporting portion of the first turntable.

[0060] S200: The first turntable rotates, and the detection component detects the positions of the multiple screens on the first supporting portion;

[0061] Specifically, step S200 includes the following steps:

[0062] Step S201: The first turntable rotates, and the multiple screens on the first supporting portion arrive at the detection assembly;

[0063] Step S202: The detection component performs image detection on the multiple screens on the first supporting portion to obtain the positions of the multiple screens on the first supporting portion. Specifically, the CCD camera of the detection component performs image detection on the multiple screens on the first supporting portion to obtain the positions of the multiple screens on the first supporting portion.

[0064] It is worth noting that, before step S201 or step S202, the X-direction moving component and / or the Y-direction moving component and / or the Z-direction moving component of the moving portion 320 of the detection assembly can adjust the X-direction position and / or the Y-direction position and / or the Z-direction position of the CCD camera, and can adjust the CCD camera to a suitable position so that the multiple screens on the first supporting part can be clearly and accurately captured in the field of view of the CCD camera.

[0065] S300: Place the screen correctly on the second turntable.

[0066] Specifically, step S300 includes the following steps:

[0067] Step S301: After obtaining the positions of the multiple screens on the first supporting portion, the compensation component of the transport assembly performs compensation adjustments on the suction cup component in the X direction and / or Y direction and / or angular direction. Specifically, based on the position of the screen on the first supporting portion detected by the detection component 300 and based on the expected position of the screen on the second supporting portion, the first compensation component 410 performs compensation adjustments on the first suction cup component 420 in the X direction and / or Y direction and / or angular direction, and / or the second compensation component performs compensation adjustments on the second suction cup component in the X direction and / or Y direction and / or angular direction.

[0068] Step S302: The first turntable continues to rotate, and the first supporting part moves to the transport assembly. Specifically, the transport assembly means that the first supporting part is close to the transport assembly, and preferably the first supporting part is located below the transport assembly. Such a setting is advantageous and can save time in transporting multiple screens.

[0069] Step S303: The transport assembly transports the multiple screens and places them correctly on the second turntable. Specifically, the transport assembly transports the multiple screens and places them correctly on the second bearing portion of the second turntable, which is the same as the content disclosed in the compensation portion above.

[0070] In step S300 , step S301 and step S302 can be performed simultaneously.

[0071] After step S300, the process also includes step S400: performing film peeling, screen corner cutting, and AOI inspection on the screen. Specifically, step S400 includes the following steps:

[0072] Step S401: The second turntable rotates, and the multiple screens on the second supporting part arrive at the film stripping station, and the film stripping operation is performed on the multiple screens. Specifically, the film stripping can be performed using a needle-type film stripping device, and the detection device is used to detect whether the film stripping is successful.

[0073] Step S402: After the multiple screens have undergone the film peeling operation, the second turntable rotates, and the multiple screens on the second supporting portion arrive at the screen corner cutting station for corner cutting. Specifically, a detection component can also be provided to detect whether the corner cutting is qualified.

[0074] Step S403: After the screens have been corner-cut, the second turntable rotates, and the screens on the second support member arrive at the AOI inspection station for AOI inspection. Specifically, the AOI inspection component checks whether the screens are qualified after processing. If qualified, the screens are unloaded.

[0075] After step S300 , the method further includes step SC: a cleaning component cleans the first carrying portion.

[0076] Specifically, step SC includes the following steps:

[0077] Step SC01: a cleaning roller of a cleaning assembly contacts a first supporting portion;

[0078] Step SC02: The cleaning roller of the cleaning assembly moves to clean the first supporting portion. Specifically, the cleaning roller can move in a front-to-back direction or in a direction close to the cleaning bracket to clean the first supporting portion.

[0079] After step S300, step SD is also included: the cleaning component cleans itself.

[0080] Specifically, step SD includes the following steps:

[0081] Step SD01: The cleaning roller of the cleaning assembly moves to contact the cleaning member on the carrier;

[0082] Step SD02 : the active roller 540 rolls, the cleaning member moves, the limiting member 541 limits the movement of the cleaning member, and the cleaning member is reeled in by the reeling roller 530 .

[0083] Step SD03: The cleaning member cleans the cleaning roller. Specifically, the cleaning member removes dust, particles, cutting chips, etc. on the cleaning roller, thereby achieving adhesion-type cleaning of the cleaning member on the cleaning roller.

[0084] It is possible to perform step SD01 and step SD02 successively, or to perform step SD02 and step SD01 successively.
