Description

Technical Field

[0001] This utility model belongs to the field of LCD screen glass substrate grinding technology, and specifically relates to a grinding belt replacement structure for LCD screen glass substrate. Background Technology

[0002] A glass substrate grinding belt for LCD screens is a strip-shaped tool used to grind the surface of a glass substrate for LCD screens. It generally consists of a flexible substrate layer and a grinding layer disposed on it. It is usually a strip structure with a certain degree of flexibility and strength, which can maintain its shape and withstand a certain amount of pressure and tension during the grinding process, and provide support for the grinding layer.

[0003] However, due to slight differences in size and flexibility between different batches of grinding belts, each batch may have slight variations in compatibility. If the position of the drive wheel cannot be flexibly adjusted, it will be difficult to adapt to these subtle changes. During installation, the grinding belt may not be able to be accurately and smoothly fitted onto the drive wheel. Operators often need to spend more effort and time adjusting the position and angle of the grinding belt and trying to find a suitable installation method. This undoubtedly greatly increases the difficulty of installation, significantly prolongs the installation time, and thus increases time costs.

[0004] To address the aforementioned issues, this application proposes a structure for replacing the grinding belt on a liquid crystal display glass substrate. Utility Model Content

[0005] To address the aforementioned problems in the prior art, this utility model provides a replacement structure for the polishing belt on a liquid crystal screen glass substrate, which facilitates the replacement of the polishing belt.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a replacement structure for a grinding belt on a liquid crystal screen glass substrate, comprising a fixed slot frame, a first transmission rod rotatably connected to the inner wall of the fixed slot frame, a second transmission rod disposed on the left side of the fixed slot frame, a controller disposed above the fixed slot frame, a rotating frame slidably connected inside the fixed slot frame, the inner wall of the rotating frame rotatably connected to the outer surface of the second transmission rod, a threaded rod, a brake motor, and a rotary motor respectively disposed on the right side of the fixed slot frame, the outer surface of the threaded rod being threadedly connected to the inner wall of the rotating frame, the end of the threaded rod near the controller being fixedly connected to the power output end of the brake motor, the power output end of the rotary motor being fixedly connected to the right end of the first transmission rod, and mounting brackets being fixedly connected to the outer surfaces of both the first and second transmission rods.

[0007] As a preferred embodiment of this utility model, a connecting plate is fixedly connected to the bottom surface of the controller, and the bottom surface of the connecting plate is fixedly connected to the upper surface of the fixing slot frame.

[0008] As a preferred embodiment of this utility model, the front and back of the fixed slot frame are fixedly connected to support frames, and the right side of each support frame is fixedly connected to a fixing plate.

[0010] As a preferred embodiment of this utility model, the bottom surface of the rotary motor is fixedly connected to a fixing frame, and the front side of the fixing frame is fixedly connected to the back side of one of the support frames.

[0011] As a preferred embodiment of this utility model, a fixed base is fixedly connected to the left side of the brake motor, and the left side of the fixed base is fixedly connected to the right side of the fixed slot frame.

[0012] As a preferred embodiment of this utility model, the outer surface of the threaded rod is rotatably connected to two limiting frames, and the left side of each limiting frame is fixedly connected to the right side of the fixed slot frame.

[0013] As a preferred embodiment of this utility model, a limiting ring is fixedly connected to the outer surface of the threaded rod, and the front of the limiting ring is in contact with the back of the rotating frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: By providing a fixed slot frame, it can be fixed to a suitable position for use in the LCD screen glass substrate grinding device.

Example

[0023] Please see Figure 1-5This utility model provides the following technical solution: a replacement structure for a grinding belt on a liquid crystal screen glass substrate, including a fixed slot frame 1, a first transmission rod 6 rotatably connected to the inner wall of the fixed slot frame 1, a second transmission rod 10 arranged on the left side of the fixed slot frame 1, a controller 2 arranged above the fixed slot frame 1, a rotating frame 12 slidably connected inside the fixed slot frame 1, the inner wall of the rotating frame 12 rotatably connected to the outer surface of the second transmission rod 10, a threaded rod 13, a brake motor 15, and a rotary motor 4 respectively arranged on the right side of the fixed slot frame 1, the outer surface of the threaded rod 13 being threadedly connected to the inner wall of the rotating frame 12, the end of the threaded rod 13 near the controller 2 being fixedly connected to the power output end of the brake motor 15, the power output end of the rotary motor 4 being fixedly connected to the right end of the first transmission rod 6, and mounting brackets 7 being fixedly connected to the outer surfaces of both the first transmission rod 6 and the second transmission rod 10. In this embodiment, the rotating frame 12 enables the second transmission rod 10 to rotate, and has internal threads to move in coordination with the rotation of the threaded rod 13.

[0024] Specifically, the bottom surface of the controller 2 is fixedly connected to the connecting plate 3, and the bottom surface of the connecting plate 3 is fixedly connected to the upper surface of the fixed slot frame 1. In this embodiment, the controller 2 can be fixed to the fixed slot frame 1 through the connecting plate 3. At the same time, the controller 2 refers to the master control device that controls the starting, speed regulation, braking and reversing of the motor by changing the wiring of the main circuit or control circuit and changing the resistance value in the circuit according to a predetermined sequence.

[0025] Specifically, the front and back of the fixed slot frame 1 are fixedly connected to support frames 5, and the right side of each support frame 5 is fixedly connected to a fixing plate 17. In this embodiment, the support frame 5 can fix the fixing plate 17 to the fixed slot frame 1, and the fixing plate 17 can be used to fix the fixed slot frame 1 for convenient use.

[0026] Specifically, each fixing plate 17 has two fixing pins 9 on its left side. The right end of each set of fixing pins 9 passes through the fixing plate 17 and extends to the right side of the fixing plate 17. In this embodiment, the fixing plate 17 can be penetrated by the fixing pins 9 and fixed to a suitable device, so that the fixing slot frame 1 can be fixed for use.

[0027] Specifically, a fixing frame 8 is fixedly connected to the bottom surface of the rotary motor 4. The front of the fixing frame 8 is fixedly connected to the back of one of the support frames 5. In this embodiment, the rotary motor 4 can be fixed to the support frame 5 through the fixing frame 8, so that the rotary motor 4 can be used stably.

[0028] Specifically, a fixing seat 16 is fixedly connected to the left side of the brake motor 15. The left side of the fixing seat 16 is fixedly connected to the right side of the fixing slot 1. In this embodiment, the brake motor 15 can be fixed to the fixing slot 1 through the fixing seat 16. At the same time, the brake motor 15 is a special motor with braking function.

[0029] Specifically, the outer surface of the threaded rod 13 is rotatably connected to two limiting brackets 14. The left side of each limiting bracket 14 is fixedly connected to the right side of the fixed slot frame 1. In this embodiment, the threaded rod 13 can be fixed to the fixed slot frame 1 through the limiting brackets 14, so that the threaded rod 13 can rotate stably.

[0030] Specifically, a limiting ring 11 is fixedly connected to the outer surface of the threaded rod 13. The front of the limiting ring 11 contacts the back of the rotating frame 12. In this embodiment, the limiting ring 11 can be fixed to the threaded rod 13 and can limit the rotation frame 12, thereby improving the stability of the movement of the rotating frame 12.

[0031] The working principle and usage process of this utility model are as follows: First, connect the rotary motor 4, the brake motor 15, and the controller 2 to the power supply. Simultaneously, connect the rotary motor 4 and the brake motor 15 to the controller 2 via wires. Using the support frame 5 and the fixing plate 17, move the fixing slot 1 to a suitable position on the LCD screen glass substrate grinding equipment. Simultaneously, use the fixing pin 9 to penetrate and fix the fixing plate 17 into the equipment, thus fixing the fixing slot 1. Then, bring the grinding belt into contact with the tension wheel of the equipment. Adjust the tension of the grinding belt using the tension wheel. When grinding is complete, use the wires to activate the controller 2 to start the rotary motor 4. The rotation of the rotary motor 4 drives the first transmission rod 6 and one of the mounting brackets 7 to rotate. Simultaneously, the rotation of the first transmission rod 6 and the mounting bracket 7 drives the grinding belt on the mounting bracket 7 and the first transmission rod 6 and the second transmission rod 10 to rotate. This allows the grinding belt to be used for grinding. When the grinding belt needs to be replaced, the controller 2 shuts off the rotary motor 4 again via the wire, and simultaneously turns on the brake motor 15 to rotate forward. The forward rotation of the brake motor 15 drives the threaded rod 13 to rotate within the limit frame 14. Simultaneously, the rotation of the threaded rod 13 and its thread cause the rotating frame 12 to move towards the controller 2 within the fixed slot frame 1. When the rotating frame 12 moves, it drives the second transmission rod 10 and one of the mounting brackets 7 to move towards the first transmission rod 6. This movement allows the grinding belt to be easily removed, and a new grinding belt is placed on the two mounting brackets 7. Then, the brake motor 15 is turned on again to rotate in reverse, causing the brake motor 15 to drive the threaded rod 13 to rotate in reverse, and the threaded rod 13 to drive the rotating frame 12, the second transmission rod 10, and one of the mounting brackets 7 back to their original positions, further facilitating the replacement of the grinding belt.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
