Description

Technical Field

[0001] This application relates to the field of laser processing technology, and in particular to a conveying mechanism used in a laser repair system. Background Technology

[0002] The core of the laser repair system lies in using a laser beam to locate and repair microscopic defects on panel products, such as bright spots and dark spots.

[0003] In current laser repair scenarios, a conveyor system transports panel products with microscopic defects to the processing station so that a laser can be used to repair these defects. However, because the panel products are placed at an angle that is slightly off-center on the conveyor system, and are prone to positional shifts due to vibrations, their orientation changes. Consequently, the panel products may not reach the processing station in a position suitable for laser repair. Inaccurate laser positioning can lead to poor repair results or even repair failure, ultimately affecting the yield rate of the panel products.

[0004] Therefore, how to provide a conveying mechanism that can prevent panel products from being placed crookedly is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] As described in the background section, in current laser repair scenarios, a conveyor transports panel products with microscopic defects to the processing station so that a laser can be emitted to repair the defects. However, because the panel products are placed at an skewed angle on the conveyor and are prone to positional shifts due to vibrations, their orientation changes. Consequently, the final position of the panel products at the processing station does not meet the requirements for laser repair. Inaccurate laser positioning leads to poor repair results or even repair failure, ultimately affecting the yield of the panel products.

[0032] Therefore, this application provides a conveying mechanism for laser repair systems, which aims to solve the technical problem of improper placement of panel products during the conveying process in the prior art.

[0033] The following analysis is based on the accompanying drawings in the instruction manual. Figures 1 to 3 A conveying mechanism for a laser repair system includes: a conveying assembly 10 configured to move a panel product 1 thereon along the production line running direction; a pushing assembly including at least one pushing unit 20 disposed on the conveying assembly 10, configured to push the panel product 1 in a direction perpendicular to the production line running direction when the panel product 1 moves to the working area of ​​the pushing unit 20, so as to straighten the position of the panel product 1 on the conveying assembly 10; the pushing unit 20 includes a bending structure 200, which abuts against the side edge of the panel product 1 when the panel product 1 is pushed.

[0034] Among them, such as Figure 1 As shown, the conveying assembly 10 moves along the production line direction A. The robotic arm in the laser repair system picks up the panel product 1 and places it on the conveying assembly 10, causing it to move with the conveying assembly 10. When the panel product 1 moves to the working area of ​​the pushing unit 20, the pushing unit 20 is activated, gently pushing the tilted panel product 1 with a preset thrust along the vertical direction B of the production line direction, so that it is aligned on the conveying assembly 10, ensuring that it is in the correct position in the subsequent laser repair process. The side edge of the panel product 1 has a single-plate structure. During the pushing process, the bending structure 200 completely abuts against the side edge of the panel product 1, forming a stable contact, enhancing the stability of the pushing process, and preventing the panel product 1 from sliding or shifting under force.

[0035] In one specific embodiment, panel product 1 is a display panel, which includes, but is not limited to, LCD, OLED, MicroLED, etc.

[0036] Preferably, refer to Figure 3 The pushing unit 20 also includes a first driving member 210 and a connecting member 220. The first driving member 210 is connected to the bending structure 200 through the connecting member 220 and is configured to drive the bending structure 200 to move.

[0037] The connector 220 achieves a stable connection between the first drive member 210 and the bending structure 200. The first drive end of the first drive member 210 can extend or retract to move the bending structure 200 toward or away from the panel product 1.

[0038] In a specific embodiment, such as Figure 3 As shown, the first drive unit 210 is mounted on the conveying assembly 10 via the mounting base 230.

[0039] In one specific embodiment, the first driving component 210 is a cylinder, the first driving end is the output end of the cylinder, and the cylinder has a preset thrust to protect the panel product 1 with glass material and prevent it from breaking or being damaged during the pushing process.

[0040] Preferably, refer to Figure 3 The bending structure 200 includes a first part 2000 and a second part 2100 that are connected to each other. The included angle between the first part 2000 and the second part 2100 is not less than 90° and not greater than 135°.

[0041] In a specific embodiment, such as Figure 3 As shown, the first part 2000 is perpendicular to the second part 2100, so that when the bending structure 200 abuts against the side edge of the panel product 1, the thrust is decomposed into horizontal and vertical components, avoiding excessive impact force at the moment of contact.

[0042] In one specific embodiment, the included angle between the first part 2000 and the second part 2100 is greater than 90° and not greater than 135°. For example, the included angle can be any value among 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, and 135°. The obtuse angle makes the contact between the bent structure 200 and the side edge of the panel product 1 smoother.

[0043] Preferably, such as Figure 1 As shown, the conveying assembly 10 includes at least two opposing frames 100 spaced at a preset distance. Each frame 100 has at least two rollers on its facing surface and a conveyor belt 110 surrounding the rollers. All rollers rotate in the same direction and at the same speed.

[0044] Here, the opposing surfaces refer to the surfaces of the two frames 100 facing each other. The fact that all the rollers rotate in the same direction ensures that the conveyor belts 110 on the two frames 100 move in the same direction, and that all the rollers rotate at the same speed ensures that the linear speeds of the conveyor belts 110 on the two frames 100 are equal.

[0045] In one specific embodiment, the conveying assembly includes a first frame 120 and a second frame 130, which are positioned opposite each other and spaced apart by a preset distance. The first frame 120 has two first rollers on its facing surfaces, and a first conveyor belt 140 is arranged around the first rollers. The second frame 130 has two second rollers on its facing surfaces, and a second conveyor belt 150 is arranged around the second rollers. The first rollers and the second rollers rotate in the same direction and at the same speed, so that the first conveyor belt 140 and the second conveyor belt 150 rotate in the same direction and at the same speed.

[0046] Preferably, refer to Figure 1 The conveying assembly 10 also includes a second drive member 160 located on one side of the frame 100, configured to drive the rollers to rotate.

[0047] In an optional embodiment, the first roller and the second roller are positioned at the same location on their respective frames 100; when the second drive member 160 is located on one side of the first frame 120, the second drive end of the second drive member 160 passes through the first roller and the second roller in sequence to drive the first roller and the second roller to rotate synchronously and in the same direction.

[0048] In an optional embodiment, when the second drive member 160 is disposed on one side of the second frame 130, the second drive end of the second drive member 160 passes through the second roller and the first roller in sequence to drive the second roller and the first roller to rotate synchronously and in the same direction.

[0049] In an optional embodiment, the second drive member 160 has dual drive ends and is located between the first frame 120 and the second frame 130. One end of the drive member is connected to the first roller and the other end is connected to the second roller. The dual drive ends synchronously drive the first roller and the second roller to rotate.

[0050] In one specific embodiment, the second driving element 160 is a single-ended motor or a double-ended motor, and the second driving end is the output end of the motor.

[0051] Preferably, refer to Figure 2 The panel product 1 is located between two frames 100 and abuts against the conveyor belts 110 on its left and right sides.

[0052] In a specific embodiment, such as Figure 1 and Figure 2As shown, panel product 1 is rectangular. In the production line running direction A, the left long side of panel product 1 abuts against the first conveyor belt 140, and the right long side abuts against the second conveyor belt 150. In actual operation, the width of the first conveyor belt 140 and the second conveyor belt 150, or the distance between the first frame 120 and the second frame 130, can be adjusted according to production needs so that the two conveyor belts can support panel product 1 and prevent panel product 1 from falling out of the gap between the two conveyor belts.

[0053] In an optional embodiment, such as Figure 1 As shown, all the pushing units 20 are arranged on the same frame 100 along the production line's running direction. For example, there are three pushing units 20. The first frame 120 has three notches in the production line's running direction A, and each pushing unit 20 is correspondingly located at a notch. When the tilted panel product 1 moves to the working area of ​​the pushing unit 20, the pushing unit 20 pushes the panel product 1 along the first frame 120 toward the second frame 130 to straighten it.

[0054] In an optional embodiment, some of the pushing units 20 are disposed on one of the frames 100, and others are disposed on another frame 100. All the pushing units 20 are staggered in the production line running direction. For example, there are five pushing units 20. The first frame 120 has two notches in the production line running direction A, and the second frame 130 has three notches in the production line running direction A. The two pushing units 20 disposed at the notches on the first frame 120 can push the panel product 1 along the direction from the first frame 120 to the second frame 130, and the three pushing units 20 disposed at the notches on the second frame 130 can push the panel product 1 along the direction from the second frame 130 to the first frame 120. On the orthographic projection plane of the conveying mechanism, the sequential connection of the five pushing units 20 is serrated.

[0055] Preferably, refer to Figure 1 and Figure 2 The mechanism also includes a detection component 30 located at the bottom of at least one conveying component 10, configured to detect the position of the panel product 1.

[0056] In one specific implementation, the detection assembly 30 includes a detection element 300 and a first mounting base 310 for fixing the detection element 300, the detection element 300 being used to detect the position of the panel product 1 on the production line using ultrasonic waves.

[0057] Preferably, the detection component 30 is connected to the pushing unit 20, and the detection component 30 is located below the working area.

[0058] Multiple detection components 30 are arranged in the production line running direction A. Most of the detection components 30 are used to detect the position of the panel product 1 on the production line in real time. The detection components 30 that are close to the push unit 20 and are pre-arranged below its working area can be used to determine whether the panel product 1 has reached the working area of ​​the push unit 20.

[0059] Preferably, the mechanism further includes at least one blocking component 40 located at the bottom of the conveying component 10, configured to block the panel product 1 that is moving along the production line running direction, so that the panel product 1 stops at a preset position.

[0060] In one specific embodiment, the blocking assembly 40 includes a blocking cylinder 400 and a second fixing seat 410 for fixing the blocking cylinder 400. The blocking cylinder 400 is used to extend its output end upward to a certain height when the panel product 1 with a problem needs to be removed, blocking the panel product 1 so that it cannot continue to move along the production line running direction A.
