[0010] Optionally, the drive module includes a linear translation module, which is used to drive the transport module to reciprocate along the first direction.

[0011] Optionally, the transport module further includes a lifting module, the output end of the linear translation module is connected to the lifting module, and the lifting module is used to drive the transported component to move up and down.

[0015] Optionally, the transport component includes a pick-up rack and a suction nozzle assembly mounted on the pick-up rack. The output end of the drive module is connected to the pick-up rack, and the suction nozzle assembly is used to pick up the display panel to be repaired or the repaired display panel on the repair platform.

[0016] Optionally, there are two repair platforms, namely a first repair platform and a second repair platform, and the unloading platform is located between the first repair platform and the second repair platform in the first direction; the two transport components are the first transport component and the second transport component.

[0028] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] like Figure 1 and Figure 2 As shown, one embodiment of this utility model provides a display panel repair device, including a machine base 1, a repair mechanism, and a display panel loading / unloading device. The display panel loading / unloading device includes a loading / unloading mechanism 4, a picking platform 5, a repair platform 2, and an unloading platform 3. The picking platform 5, the repair platform 2, and the unloading platform 3 are arranged on the machine base 1 and are distributed sequentially at intervals along a first direction. The picking platform 5 is used to place the display panel to be repaired, and the repair mechanism is used to repair the display panel to be repaired on the repair platform 2. Figure 2 In this context, D1 represents the first direction.

[0030] Specifically, the repair mechanism includes a laser, which uses laser light to create a gap between the color filter of the pixel and the glass substrate of the display panel to be repaired. Then, the laser is used to granulate the black matrix around the pixel and push the generated black particles into the gap. This process is repeated until the black particles completely cover the bright spot of the pixel, and the repair is finally completed.

[0031] The loading and unloading mechanism 4 includes a drive module 41 and a transport module. The transport module includes two transport components 42 that are spaced apart along a first direction. The drive module 41 is used to drive the transport module to reciprocate between the picking position and the loading and unloading position. The picking position and the loading and unloading position are spaced apart along the first direction.

[0032] When the transport module is in the picking position, one transport component 42 can pick up the display panel to be repaired on the picking platform 5, and the other transport component 42 can pick up the repaired display panel on the repair platform 2. When the transport module is in the unloading position, one transport component 42 can place the picked-up display panel to be repaired on the repair platform 2, and the other transport component 42 can place the picked-up repaired display panel on the unloading platform 3.

[0033] Specifically, when the display panel loading and unloading device is working, the drive module 41 first drives the transport module to the picking position, so that one transport component 42 can pick up the display panel to be repaired, and the other transport component 42 can pick up the repaired display panel on the repair platform 2. Then, the drive module 41 drives the two transport components 42 of the transport module to move to the loading and unloading positions. During the process of the drive module 41 driving the transport module to move to the loading and unloading positions, the transport component 42 picking up the display panel to be repaired and the other transport component 42 picking up the repaired display panel move synchronously. When the transport components move to the loading and unloading positions, one transport component 42 places the picked-up display panel to be repaired on the repair platform 2, and the other transport component 42 places the picked-up repaired display panel on the unloading platform 3, so as to realize the loading action of the repair platform 2 and the unloading action of the unloading platform 3, so that the subsequent repair mechanism can repair the display panel to be repaired on the repair platform 2, and the repaired display panel on the unloading platform 3 can be transported out by the conveying device or the unloading device.

[0034] The present invention discloses a display panel loading and unloading device. The loading and unloading mechanism 4 includes a conveying module comprising two conveying components 42 spaced apart along a first direction. A driving module 41 drives the two conveying components 42 of the conveying module to move synchronously, enabling the two conveying components 42 to move synchronously to the picking position or the loading / unloading position. When the conveying module is in the loading / unloading position, one conveying component 42 can place the display panel to be repaired picked up at the picking position onto the repair platform 2, and the other conveying component 42 can place the repaired display panel picked up from the repair platform 2 at the picking position onto the unloading platform 3, so that the loading / unloading mechanism 4 can load the repair platform 2 and unload the unloading platform 3.

[0035] Compared to the existing technology that uses two conveying mechanisms to load the repair platform 2 and unload the unloading platform 3 respectively, in this utility model, the two conveying components 42 of the conveying module 4 are driven by the drive module 41 to move synchronously. One conveying component 42 is used to load the repair platform 2 and the other conveying component 42 is used to unload the unloading platform 3. This avoids the situation where two conveying mechanisms need to avoid each other and wait, as well as the situation where collisions are easily caused by misoperation.

[0036] In one embodiment, when the transport module is in the loading / unloading position, one transport component 42 is located directly above the repair platform 2, and the other transport component 42 is located directly above the unloading platform 3. This allows one transport component 42 to load the picked-up display panel to be repaired onto the repair platform 2 while the other transport component 42 can unload the picked-up repaired display panel onto the unloading platform 3, so that the two transport components 42 can perform loading and unloading actions synchronously, thereby improving the processing efficiency of the equipment.

[0037] In one embodiment, such as Figure 1 As shown, the material handling platform 5 is a correction platform, which is set on the machine base 1 and is used to place the display panel to be repaired.

[0038] When the transport module is in the picking position, the drive module 41 can drive a transport component 42 to move directly above the correction platform so that the corresponding transport component 42 can pick up the display panel to be repaired on the correction platform.

[0039] It should be noted that the correction stage can be a UVW alignment platform. After the display panel to be repaired is placed on the UVW alignment platform, the UVW alignment platform works in conjunction with the pre-alignment camera mechanism. The camera takes pictures to locate the position of the display panel to be repaired, and the UVW alignment platform is moved or rotated to adjust the display panel to the preset position, so that the subsequent transport component 42 can pick up the display panel to be repaired from the preset position.

[0040] In one embodiment, such as Figure 2As shown, the drive module 41 includes a linear translation module, which drives the transport module to reciprocate linearly along a first direction, so that the transport component 42 of the transport module can move linearly to directly above each platform to perform material picking, loading, or unloading actions. The linear motion of the transport module is simple and easy to implement.

[0041] In one embodiment, such as Figure 2 As shown, the conveying module also includes a lifting module. The output end of the linear translation module is connected to the lifting module. The lifting module is used to drive the conveying component 42 to lift, so that the conveying component 42 is closer to each platform at the picking position and the loading and unloading position, so as to pick up the display panel or accurately place the display panel on the corresponding platform.

[0042] In one embodiment, such as Figure 2 As shown, the lifting module includes a connecting base 45, a first lifting module 43, and a second lifting module 44. The output end of the linear translation module is connected to the connecting base 45. The first lifting module 43 and the second lifting module 44 are mounted on the connecting base 45. The first lifting module 43 is used to drive one transport component 42 to lift, and the second lifting module 44 is used to drive another transport component 42 to lift, so that the lifting actions of the two transport components 42 are independent of each other, thereby allowing the lifting height of the transport component 42 to be adjusted according to the height of the corresponding platform.

[0043] In one embodiment, the first lifting module 43 and the second lifting module 44 have the same structure, and the first lifting module 43 and the second lifting module 44 can be cylinders.

[0044] In one embodiment, the linear translation module includes a fixed frame 413, a slide block 411, and a linear actuator 412. The slide block 411 is slidably mounted on the fixed frame 413 along a first direction and connected to the transport module. The slide block 411 constitutes the output end of the linear translation module.

[0045] The linear actuator 412 is used to drive the slide block 411 to slide, so as to drive the transport module to reciprocate along the first direction.

[0046] In one embodiment, such as Figure 2 As shown, the fixed frame 413 includes a crossbeam and two columns. The crossbeam extends along the first direction, and the two ends of the crossbeam are respectively connected to the tops of the two columns. The material picking platform 5, the repair platform 2 and the unloading platform 3 are all located between the two columns. A linear guide rail is installed on the bottom side of the crossbeam, and the slide 411 is slidably installed on the linear guide rail.

[0047] In one embodiment, the linear actuator 412 includes a motor, a lead screw, and a nut. The nut is fixed on the slide 411. The lead screw is rotatably mounted on the crossbeam and passes through the nut in a first direction. The motor drives the lead screw to rotate about its own axis so that the nut moves along the lead screw, thereby causing the slide 411 to slide in the first direction.

[0048] In other embodiments, the linear actuator 412 may be a cylinder, a hydraulic cylinder, or the like.

[0049] In one embodiment, such as Figure 2 As shown, the transport component 42 includes a pick-up rack 422 and a suction nozzle assembly 421 mounted on the pick-up rack 422. The output end of the drive module 41 is connected to the pick-up rack 422. The suction nozzle assembly 421 is used to pick up the display panel to be repaired or the repaired display panel on the repair platform 2.

[0050] Specifically, the suction nozzle assembly 421 includes a control device and multiple suction nozzle bodies spaced apart. When the transport member 42 picks up the display panel to be repaired or the repaired display panel on the repair platform 2, the control device controls the multiple suction nozzle bodies to open, the air inside the suction nozzle bodies is extracted or expelled, the air pressure inside the suction nozzle bodies decreases, while the air pressure of the external environment remains unchanged, creating a pressure difference so that the suction nozzle bodies can hold the display panel. When the transport member 42 places the display panel to be repaired or the repaired display panel on the corresponding platform, the control device controls the suction nozzle bodies to close.

[0051] In one embodiment, such as Figure 1 As shown, there are two repair platforms 2, namely the first repair platform 2A and the second repair platform 2B. The unloading platform 3 is located between the first repair platform 2A and the second repair platform 2B in the first direction. The two transport components 42 are the first transport component 42A and the second transport component 42B.

[0052] The material picking positions include the first material picking position and the second material picking position, and the loading and unloading positions include the first loading and unloading positions and the second loading and unloading positions.

[0053] When the transport module is in the first picking position, the first transport component 42A can pick up the display panel to be repaired, and the second transport component 42B can pick up the repaired display panel on the first repair platform 2A. When the transport module is in the first unloading position, the first transport component 42A can place the picked-up display panel to be repaired on the first repair platform 2A, and the second transport component 42B can place the picked-up repaired display panel on the unloading platform 3.

[0054] When the transport module is in the second picking position, the second transport member 42B can pick up the display panel to be repaired, and the first transport member 42A can pick up the repaired display panel on the second repair platform 2B. When the transport module is in the second unloading position, the second transport member 42B can place the picked-up display panel to be repaired on the second repair platform 2B, and the first transport member 42A can place the picked-up repaired display panel on the unloading platform 3.

[0055] By using a loading and unloading mechanism 4 to load and unload materials onto two repair platforms 2, the utilization rate of the loading and unloading mechanism 4 is improved and the cost is reduced.

[0056] In one embodiment, the material handling position includes a correction material handling position and a repair material handling position. When the transport module is located at the correction material handling position, one transport component 42 is positioned directly above the material handling platform 5, so that the transport component 42 can pick up the display panel to be repaired on the material handling platform 5. When the transport module is located at the repair material handling position, another transport component 42 is positioned directly above the repair platform 2, so that the transport component 42 can pick up the repaired display panel on the repair platform 2.

[0057] Specifically, the drive module 41 first drives the transport module to the correction and picking position. The transport component 42, located directly above the picking platform 5, picks up the display panel to be repaired on the picking platform 5. At this time, the other transport component 42 is empty. Then, the drive module 41 drives the transport module to the repair picking position, so that the other transport component 42 is directly above the repair platform 2. After the transport component 42 picks up the repaired display panel on the repair platform 2, the drive module 41 drives the transport module to the loading and unloading position.

[0058] In other embodiments, the picking platform 5 may simply be a platform for placing the product to be repaired. The product to be repaired may be conveyed to the picking platform 5 by a transmission device, or it may be manually handled or handled by grippers.

[0059] In addition, one embodiment of this utility model provides a display panel loading and unloading device, the structure of which is the same as that of the display panel loading and unloading device in any of the above embodiments, and will not be described again here.

[0060] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
