Description

Technical Field

[0001] This application relates to the field of laser processing technology, and more particularly to a display panel laser processing device. Background Technology

[0002] Display panels are components in electronic devices (such as computer monitors, mobile phones, and tablets) that convert electrical signals into visible text or images. During the manufacturing process, microscopic defects (such as bright spots or dark spots) may occur, negatively impacting the yield of the finished panels. Therefore, laser repair equipment is used to precisely repair these detected microscopic defects on display panels, preventing their scrapping and reducing production costs.

[0003] In current laser repair scenarios, robotic arms place the display panel at the processing station, and the display panel maintains its position by gravity. When the laser repair equipment moves or is disturbed by external forces, it will vibrate. The vibration is directly transmitted to the display panel, exacerbating the instability of the display panel and causing it to shift, which affects the stability and processing accuracy of subsequent laser repair.

[0004] Therefore, how to provide a laser device that can stabilize the position of the display panel is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] This application provides a display panel laser processing equipment that achieves stable clamping of panel products and avoids panel position displacement caused by equipment vibration or external force interference during laser processing.

[0006] To address the technical problems existing in the prior art, the following technical solution is adopted:

[0013] Preferably, the device further includes a second driving member and a blocking member vertically connected to a second driving end of the second driving member. The second driving end is configured to be rotatable, so that the blocking member starts to make a circular motion from an initial position until the blocking member stops when it abuts against the side wall of the panel product. The initial position is located on one side of the panel product.

[0014] Preferably, the second driving end is a shaft, and the axial direction of the second driving end is perpendicular to the pushing direction of the first driving member.

[0015] Preferably, on the side projection surface of the device, when the blocking member is located at the initial position, the angle between the blocking member and the long sidewall of the panel product is an acute angle.

[0016] Preferably, there are two second driving members, one located on the first side and the other on the second side.

[0017] Preferably, on the orthographic projection surface of the device, the blocking member is rectangular or right-angled trapezoidal.

[0018] Preferably, the device further includes a displacement mechanism disposed on one side of the limiting plate and connected to the laser processing mechanism, configured to drive the laser processing mechanism to move in a direction closer to or further away from the limiting space.

[0019] Preferably, the device further includes a mounting plate disposed below the limiting plate, wherein when the panel product is placed in the limiting space, its bottom surface abuts against the mounting plate and its top surface faces the laser processing mechanism.

Detailed Implementation

[0028] 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.

[0029] As described in the background section, in current laser repair scenarios, a robotic arm places the display panel at the processing station. The display panel maintains its position by gravity. When the laser repair equipment moves or is disturbed by external forces, it will vibrate. The vibration is directly transmitted to the display panel, exacerbating its instability and causing it to shift, which affects the stability and processing accuracy of subsequent laser repair.

[0030] Therefore, this application provides a display panel laser processing equipment, which aims to solve the technical problem of vibration displacement of panel products in laser repair scenarios in the prior art.

[0031] The following analysis is based on the accompanying drawings in the instruction manual. Figures 1 to 3 A display panel laser processing device includes: a U-shaped limiting plate 10 having a first side 100 and a second side 110 opposite each other in the length direction, forming a limiting space between the first side 100 and the second side 110 for limiting the position of a panel product 1; a first driving member 20 disposed on one side of the limiting plate 10, configured to push the panel product 1 so that the panel product 1 abuts against the other side of the limiting plate 10; and a laser processing mechanism 30 disposed above the limiting space, configured to emit a laser to act on the panel product 1.

[0032] Among them, such as Figure 1 It is known that on the orthographic projection surface of the equipment, the area of ​​the limiting space is larger than the area of ​​panel product 1, allowing panel product 1 to be placed within the limiting space. When the robotic arm outside the laser processing equipment transports panel product 1 to the limiting space, the first driving component 20 located on one side of the limiting plate 10 is activated to push panel product 1, causing panel product 1 to abut against the other side of the limiting plate 10. That is, the first driving component 20 and the limiting plate 10 form a stable clamping structure, fixing panel product 1 in a processing station within the limiting space. This avoids panel position displacement caused by equipment vibration or external interference during processing, thus enabling the laser processing mechanism to accurately emit laser light to act on panel product 1, ensuring the stability of the laser processing process.

[0033] In one specific embodiment, panel product 1 is a display panel, including but not limited to LCD, OLED, MicroLED, etc.; the first driving component 20 is a cylinder.

[0034] In one specific embodiment, reference Figures 1 to 3 The equipment also includes a mounting plate 80 located below the limiting plate 10. When the panel product 1 is placed in the limiting space, its bottom surface abuts against the mounting plate 80, and its top surface faces the laser processing mechanism 30.

[0035] The mounting plate 80 provides support for the panel product 1, and the combination of the first driving component 20 and the limiting plate 10 clamps it, preventing the panel product 1 from shifting, so that the laser processing mechanism 30 can accurately emit laser light to act on the surface of the panel product 1.

[0036] In one specific embodiment, the laser processing mechanism 30 may use ultraviolet laser, infrared laser, green laser, etc. to act on the surface of the display panel to repair microscopic defects.

[0037] Preferably, refer to Figures 1 to 3 The first driving member 20 is disposed on the first side 100. The first driving end of the first driving member 20 is configured to extend and retract along the length direction of the limiting plate 10, and the first driving end is located in front of the panel product 1 in the direction from the second side 110 to the first side 100.

[0038] As can be seen from the foregoing embodiments, the first driving member 20 can be a cylinder, and the first driving end is the output end of the cylinder. The movable direction of the cylinder output end is consistent with the length direction of the limiting plate 10. Only by placing the first driving member 20 in front of the panel product 1 can it be ensured that the first driving member 20 pushes the panel product 1, causing the panel product 1 to abut against the second side 110, thereby achieving the clamping of the panel product 1.

[0039] In one specific embodiment, when the panel product 1 is placed in the limiting space, there is a certain distance between it and the second side 110 of the limiting plate 10. At this time, the first driving member 20 is activated, the first driving end extends and pushes the panel product 1 toward the second side 110 until the panel product 1 touches the second side 110 and the first driving member 20 stops.

[0040] Preferably, refer to Figures 1 to 3 The device also includes a push plate 40 connected to the first drive end, the length of which matches the width of the panel product 1.

[0041] If the length of the push plate 40 is too large, it will result in high manufacturing costs and will not save internal space. If the length is too small, the contact area with the panel product 1 will be small, and the thrust will be too concentrated when pushing the panel product 1, which may damage the panel product 1. Therefore, the length of the push plate 40 can be set according to the width of the panel product 1 so that the push plate 40 has a suitable contact area when it contacts the panel product 1, ensuring that the thrust is evenly distributed on the wide sidewall of the panel product 1 and avoiding local stress concentration.

[0042] Preferably, refer to Figures 1 to 3 The device also includes a second drive member 50 and a blocking member 60 vertically connected to the second drive end of the second drive member 50. The second drive end is configured to be rotatable, so that the blocking member 60 starts to make a circular motion from the initial position until the blocking member 60 stops when it abuts against the side wall of the panel product 1. The initial position is located on one side of the panel product 1.

[0043] As can be seen from the aforementioned embodiments, the first driving member 20 pushes one wide sidewall of the panel product 1, causing the other wide sidewall of the panel product 1 to abut against the second side 110, thereby clamping the panel product 1; after the panel product 1 is stabilized, the second driving member 50 drives the blocking member 60 to rotate to the long sidewall of the panel product 1 and abut against its long sidewall, thereby achieving secondary limiting and blocking of the panel product 1, further improving the stability of the panel product 1 placed in the limiting space.

[0044] In one specific embodiment, when the robotic arm places the panel product 1 in the limiting space, one long side wall of the panel product 1 will abut against the inner wall of the limiting plate 10. The first driving member 20 pushes one wide side wall of the panel product 1, causing the other wide side wall to abut against the second side 110. The second driving member 50 drives the blocking member 60 to rotate, causing the blocking member 60 to abut against the other long side wall of the panel product 1. In this way, the panel product 1 is omnidirectionally limited and stabilized.

[0045] In an optional embodiment, the second driving member 50 is located close to the first driving member 20 and is disposed on the mounting plate 80. The second driving end is a shaft, and the axial direction of the second driving end is perpendicular to the pushing direction of the first driving member 20 and perpendicular to the mounting plate 80. The blocking member 60 is located on the left side of the panel product 1 in the initial position, and rotates to the long sidewall of the panel product 1 under the drive of the second driving member 50. On the orthographic projection plane of the device, when the blocking member 60 is in the initial position, the angle between the blocking member 60 and the long sidewall of the panel product 1 is an acute angle.

[0046] In an optional embodiment, such as Figures 1 to 3 As shown, the second driving member 50 is disposed on the first side 100 of the limiting plate 10 and is located below the first driving member 20. The second driving end is a shaft, and the axial direction of the second driving end is perpendicular to the pushing direction of the first driving member 20 and parallel to the mounting plate 80. The blocking member 60 is located on the upper side of the panel product 1 in the initial position, and rotates to the long side wall of the panel product 1 under the drive of the second driving member 50. On the side projection plane of the device, when the blocking member 60 is in the initial position, the angle between the blocking member 60 and the long side wall of the panel product 1 is an acute angle.

[0047] In one specific embodiment, the aforementioned second driving member 50 may be a motor, and the second driving end of the second driving member 50 is the output shaft of the motor.

[0048] In an optional embodiment, such as Figure 2 and Figure 3 As shown, there is one second driving member 50, which is located on the first side 100 of the limiting plate 10 to abut against one end of the long side wall of the panel product 1.

[0049] In an optional embodiment, such as Figure 1 As shown, there are two second driving members 50, one of which is located on the first side 100 and the other on the second side 110, to achieve double-end contact with the long sidewall of the panel product 1.

[0050] In one specific embodiment, reference Figure 1 and Figure 2 On the orthographic projection surface of the device, the blocking element 60 is rectangular or right-angled trapezoidal.

[0051] Preferably, refer to Figure 2 and Figure 3 The equipment also includes a displacement mechanism 70 located on one side of the limiting plate 10 and connected to the laser processing mechanism 30, configured to drive the laser processing mechanism 30 to move in a direction closer to or further away from the limiting space.

[0052] In a specific embodiment, such as Figure 3 As shown, the displacement mechanism 70 includes a bracket 700; a first guide rail 710 and a slider slidably connected to the first guide rail 710, the first guide rail 710 being disposed on the bracket 700 and extending in the same direction as the height direction of the bracket 700; a second guide rail 720 and a sliding plate 730 slidably connected to the second guide rail 720, the extension direction of the second guide rail 720 being perpendicular to the height direction of the bracket 700. Figure 3 For example, the displacement mechanism 70 is located on one side of the limiting plate 10, and the bracket 700 is located on the sliding plate 730. It can move left and right along the second guide rail 720 via the sliding plate 730. The laser processing mechanism 30 is connected to the slider via the connecting plate 740. It can move up and down along the height direction of the first guide rail 710 via the slider. In this way, the laser processing mechanism 30 can be moved to move accurately above the panel product 1 to perform defect repair operation on the surface of the panel product 1.
