Description

Technical Field

[0001] The utility model relates to the technical field of liquid crystal panel processing, and particularly relates to a coating clamping mechanism for a liquid crystal panel. Background Technique

[0002] In the process of processing a liquid crystal panel, one of the processes is to coat a conductive film on the surface of the glass panel of the liquid crystal panel by using low-temperature magnetron sputtering.

[0003] For example, the utility model patent with the publication number of CN210030453U provides a fixture for vacuum coating of liquid crystal panel glass, which includes a fixed base. Above the fixed base, a top plate is fixedly installed through two symmetrically arranged fixed columns. Between the fixed base and the top plate, a first clamping seat and a second clamping seat are installed. The first clamping seat is located above the second clamping seat. A liquid crystal panel is clamped between the first clamping seat and the second clamping seat. Slots are recessed on the opposite sides of the first clamping seat and the second clamping seat. The upper and lower sides of the liquid crystal panel are respectively inserted into the two slots. Two vertically arranged clamping motors are symmetrically and fixedly installed on the top of the top plate. The driving end of each clamping motor is fixedly installed with a bidirectional screw. It drives the two clamping seats to move towards the liquid crystal panel in the middle through the clamping motors and the bidirectional screws, and clamps the liquid crystal panel between the two slots.

[0004] However, the existing coating fixture uses the clamping seat to clamp and fix the glass panel. When clamping, the clamping seat will contact the surface of the glass panel, resulting in the surface of the glass panel not being able to fully contact the plating solution, thereby affecting the coating quality. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the above technical deficiencies, and propose a coating clamping mechanism for a liquid crystal panel, so as to solve the technical problem that after the glass panel is clamped by the fixture in the prior art, the surface of the glass panel cannot fully contact the plating solution, thereby affecting the coating quality.

[0006] To achieve the above technical purpose, the utility model adopts the following technical solutions:

[0007] The utility model provides a coating clamping mechanism for a liquid crystal panel, which includes: a suction member, a driving member, and two positioning members.

A clamping area is formed on one side of the vacuum suction cup; the driving member is connected to the mounting plate and is used to drive the vacuum suction cup to move relative to the clamping area; the two positioning members are respectively arranged on both sides of the clamping area, and the end close to the clamping area forms a clamping end, and the other end is connected to the mounting plate. When the vacuum suction cup moves towards or away from the clamping area, the two clamping ends can approach or move away from each other under the drive of the mounting plate.

[0008] In some embodiments, the liquid crystal panel coating clamping mechanism also includes a base, a support rod, a workbench and a support frame. The workbench is fixed above the base by four support rods. A through groove for accommodating the mounting plate is opened in the middle of the workbench, and the driving member is installed on the base; the support frame is connected to the workbench and is arranged between the mounting plate and the clamping area.

[0013] Compared with the prior art, the liquid crystal panel coating clamping mechanism provided by the utility model can drive the vacuum chuck to move towards the clamping area through the arranged adsorbing member, driving member and two positioning members. When the vacuum chuck moves towards the clamping area, the two clamping ends of the two positioning members can approach each other under the drive of the mounting plate, and can clamp the liquid crystal panel in the clamping area.

[0025] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further describes the present utility model in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] In order to solve the technical problem that after clamping a glass panel by a fixture, the surface of the glass panel cannot fully contact the plating solution, thereby affecting the coating quality, the present utility model provides a clamping mechanism for coating a liquid crystal panel, which is convenient and fast to clamp, ensures that one side of the liquid crystal panel to be coated can fully contact the plating solution, and can obtain a uniform coating layer and good quality.

[0027] Please refer to Figures 1 to 6 , the clamping mechanism for coating a liquid crystal panel includes: a suction member 1, a driving member 2 and two positioning members 3. The suction member 1 includes a vacuum chuck 11 and a mounting plate 12. The vacuum chuck 11 is mounted on the mounting plate 12 and connected to a vacuum pump. A clamping area is formed on one side of the vacuum chuck 11; the driving member 2 is connected to the mounting plate 12 and is used to drive the vacuum chuck 11 to move relative to the clamping area; the two positioning members 3 are respectively arranged on both sides of the clamping area, and a clamping end is formed at one end close to the clamping area, and the other end is connected to the mounting plate 12. When the vacuum chuck 11 moves towards or away from the clamping area, the two clamping ends can approach or move away from each other under the drive of the mounting plate 12.

[0028] In this device, the driving member 2 is connected to the driving mounting plate 12. The driving member 2 can drive the vacuum chuck 11 to move towards the clamping area through the mounting plate 12. The vacuum chuck 11 is connected to a vacuum pump, and the vacuum pump can be used to generate and maintain a vacuum in the inner cavity of the vacuum chuck 11, thereby adsorbing one side of the liquid crystal panel. The two positioning members 3 are respectively arranged on both sides of the clamping area. When the vacuum chuck 11 moves towards the clamping area, the two clamping ends of the two positioning members 3 can approach each other under the drive of the mounting plate 12, and can clamp the liquid crystal panel in the clamping area. Through the clamping and positioning of the liquid crystal panel by the positioning members 3, when the vacuum chuck 11 moves towards the clamping area, it can fully abut against one side of the liquid crystal panel, which is beneficial to improving the adsorption effect of the vacuum chuck 11 on the liquid crystal panel. When the vacuum chuck 11 moves away from the clamping area, the two clamping ends of the two positioning members 3 can move away from each other under the drive of the mounting plate 12, so that the positioning members 3 are away from the surface of the liquid crystal panel. The device is fixed only by adsorbing the other side of the liquid crystal panel with the adsorbing member 1, ensuring that the coated side of the liquid crystal panel can fully contact the plating solution to obtain a uniform coating and good quality.

[0029] Of course, when performing other processing, the adsorbing member 1 and the positioning members 3 can also be used simultaneously to adsorb and clamp the liquid crystal panel, further ensuring the stability of the liquid crystal panel during processing.

[0030] In order to install the adsorbing member 1, the driving member 2 and the positioning members 3, in this embodiment, please refer to Figures 1 to 5 , the liquid crystal panel coating clamping mechanism further includes a base 4, a support rod 5, a workbench 6 and a support frame 7. The workbench 6 is arranged above the base 4 and is fixedly connected to the base 4 through four support rods 5 at the four corners. A through groove is formed in the middle of the workbench 6 to facilitate the movement of the adsorbing member 1 at the through groove. The driving member 2 includes a cylinder 21, and the bottom end of the cylinder 21 is installed on the upper surface of the base 4. The telescopic shaft at the top end of the cylinder 21 is connected to the mounting plate 12. The support frame 7 is fixedly connected to the workbench 6 and is arranged between the mounting plate 12 and the clamping area. The cylinder 21 drives the mounting plate 12 and the vacuum chuck 11 to move downward, so that after the positioning members 3 are opened, the support frame 7 can support the bottom of the liquid crystal panel to further improve the stability of the liquid crystal panel.

[0031] In order to improve the fixing effect of the adsorbing member 1, in this embodiment, please refer to Figures 1 to 4, there are four vacuum suction cups 11, and the four vacuum suction cups 11 are installed in an array on the mounting plate 12. Specifically, four mounting holes are opened on the mounting plate 12, which correspond to the positions where the four vacuum suction cups 11 need to be installed. A connecting pipe 13 is provided on one side of each vacuum suction cup 11, and a positioning sleeve 14 and a threaded sleeve 15 are provided on the connecting pipe 13. The positioning sleeve 14 is fixedly connected to the connecting pipe 13, and the threaded sleeve 15 is threadedly connected to the connecting pipe 13. The connecting pipe 13 is inserted and connected to the mounting hole. After the positioning sleeve 14 contacts the upper surface of the mounting plate 12, the threaded sleeve 15 is threadedly connected to the bottom end of the connecting pipe 13, so that the connecting pipe 13 and the vacuum suction cup 11 can be installed and fixed. The connecting pipe 13 is a hard pipe, and the suction cup cavity of the vacuum suction cup 11 is connected to the vacuum pump through the connecting pipe 13 and the hose.

[0032] In order to realize automatic clamping and loosening of the liquid crystal panel, in this embodiment, refer to Figures 3 to 5 The two positioning members 3 are respectively located between the two vacuum suction cups 11 on both sides of the mounting plate 12, so that the positioning members 3 are staggered with the vacuum suction cups 11. The two positioning members 3 each include a mounting base 31, a support base 32, a first connecting rod 33, a second connecting rod 34, and a clamping plate 35. The mounting base 31 is fixed to the bottom of the mounting plate 12, and the support base 32 is fixedly installed above the workbench 6. One end of the first connecting rod 33 is rotatably connected to the mounting base 31, and the other end is rotatably connected to one end of the second connecting rod 34. The other end of the second connecting rod 34 is fixedly connected to the clamping plate 35. The middle part of the second connecting rod 34 is rotatably connected to the support base 32. The clamping plates 35 are arranged on both sides of the clamping area for clamping on both sides of the liquid crystal panel.

[0033] In order to further improve the adsorption effect of the adsorption element 1, please refer to Figure 6 An ear plate 37 is provided on one side of the clamping plate 35 close to the clamping area. The ear plate 37 is fixed to the top end of the clamping plate 35. The ear plate 37 is used to press against the side of the liquid crystal panel away from the vacuum suction cup 11 when the clamping plate 35 is clamped on the liquid crystal panel.

[0034] During implementation, when the cylinder 21 drives the mounting plate 12 to move upward, it drives the vacuum suction cup 11 to move upward. As the mounting plate 12 moves upward, it also drives the mounting seat 31 to move upward. Thereby, through the first connecting rod 33, the second connecting rod 34 is driven to rotate, causing the tops of the two clamping plates 35 to approach each other until they are clamped on both sides of the liquid crystal panel. At the same time, the ear plate 37 abuts above the liquid crystal panel. By continuously applying force with the cylinder 21, the vacuum suction cup 11 is pressed tightly below the liquid crystal panel. At this time, a negative pressure can be generated in the vacuum suction cup 11 by using a vacuum pump to achieve the adsorption and fixation of the liquid crystal panel. When the cylinder 21 drives the mounting plate 12 to move downward, it drives the vacuum suction cup 11 to move downward. As the mounting plate 12 moves downward, it also drives the mounting seat 31 to move downward. Thereby, through the first connecting rod 33, the second connecting rod 34 is driven to rotate, causing the two clamping plates 35 to move away from each other until they are away from the liquid crystal panel.

[0035] Further, please refer to Figure 6 , in order to avoid the clamping plate 35 from causing wear to the liquid crystal panel, a rubber pad 36 is further provided on one side of the clamping plate 35 close to the clamping area. During clamping, the liquid crystal panel contacts the rubber pad 36.

[0036] Working principle: During implementation, the liquid crystal panel can be placed above the four vacuum suction cups 11. Then, the cylinder 21 drives the mounting plate 12 to move upward, driving the vacuum suction cup 11 to move upward. As the mounting plate 12 moves upward, it also drives the mounting seat 31 to move upward. Thereby, through the first connecting rod 33, the second connecting rod 34 is driven to rotate, causing the tops of the two clamping plates 35 to approach each other until they are clamped on both sides of the liquid crystal panel. At the same time, the ear plate 37 abuts above the liquid crystal panel. By continuously applying force with the cylinder 21, the vacuum suction cup 11 is pressed tightly below the liquid crystal panel. Then, a negative pressure is generated in the vacuum suction cup 11 by using a vacuum pump to achieve the adsorption and fixation of the liquid crystal panel. Subsequently, the cylinder 21 drives the mounting plate 12 to move downward, driving the vacuum suction cup 11 to move downward. As the mounting plate 12 moves downward, it also drives the mounting seat 31 to move downward. Thereby, through the first connecting rod 33, the second connecting rod 34 is driven to rotate, causing the two clamping plates 35 to move away from each other until they are away from the liquid crystal panel. At this time, there are no obstacles on the upper surface of the liquid crystal panel, and the coating work can be carried out.

[0037] The utility model is provided with an adsorbing member 1, a driving member 2 and two positioning members 3. The driving member 2 can drive the vacuum chuck 11 to move towards the clamping area. When the vacuum chuck 11 moves towards the clamping area, the two clamping ends of the two positioning members 3 can approach each other under the drive of the mounting plate 12, and can clamp the liquid crystal panel in the clamping area. Through the clamping and positioning of the liquid crystal panel by the positioning member 3, when the vacuum chuck 11 moves towards the clamping area, it can fully abut against one side of the liquid crystal panel, which is beneficial to improving the adsorption effect of the vacuum chuck 11 on the liquid crystal panel, and can stably adsorb and fix the liquid crystal panel, and the clamping is convenient and fast; when the vacuum chuck 11 moves away from the clamping area, the two clamping ends of the two positioning members 3 can move away from each other under the drive of the mounting plate 12, so that the positioning member 3 is away from the surface of the liquid crystal panel. The device is fixed only by adsorbing the other side of the liquid crystal panel by the adsorbing member 1, ensuring that the coated side of the liquid crystal panel can fully contact the plating solution to obtain a uniform coating and good quality.

[0038] The specific embodiments of the utility model described above do not constitute a limitation to the protection scope of the utility model. Any other corresponding changes and deformations made according to the technical concept of the utility model shall be included in the protection scope of the claims of the utility model.
