Description

Technical Field

[0001] The utility model relates to the technical field of touch screen processing, in particular to a multifunctional clamp for touch screen processing. Background Art

[0002] A touch screen, also known as a "touch screen" or "touch panel", is an inductive liquid crystal display device that can receive input signals such as contacts. During the production and processing of the touch screen, it is usually necessary to use a clamp to clamp it and fix it to facilitate its processing.

[0003] my country's public patent, application number CN202221399305.0, mentions a universal touch screen clamp: "A base plate, the four end corners of the top of the base plate are fixedly installed with support columns, and the tops of the support columns are fixedly installed with fixed blocks. The utility model cooperates with the movable rod and the compression spring, so that when the device clamps the touch screen, it first pushes the anti-wear pad into the inside of the spring groove, and then places the touch screen on the surface of the support plate. At this time, the movable rod will rebound due to the elastic potential energy of the compression spring, so that the anti-wear pad is stuck in the four end corners of the touch screen, so that the touch screen is clamped firmly, so that the device can clamp touch screens of different sizes. Through the cooperation of the top buckle of the fixing plate and the bottom groove of the fixing rod, the device can insert the anti-wear pad into the outer surface of the triangular fixing plate at any time, so that the outer surface of the touch screen is protected by the anti-wear pad, and the triangular fixing plate is prevented from causing serious wear on the outer surface of the touch screen."

[0004] The utility model retrieved above clamps the touch screen at the four corners through a fixture, thereby clamping it to facilitate subsequent processing, and can clamp touch screens of different sizes. Although this method achieves the claimed technical effect, we found that the technology still has certain defects during specific simulation use:

[0005] First, it is difficult to clamp the touch screen with the existing technology. Since the side of the touch screen is close to the frame, there are certain inconveniences when processing the side of the touch screen, which makes it difficult to process the side of the touch screen. In addition, the position of the touch screen is relatively fixed, and it is difficult for the staff to process other parts of the touch screen at the same workstation. There is a problem that the staff needs to move around to process multiple parts of the touch screen.

[0006] Second, the existing technology can only clamp a touch screen with a square structure, but it is difficult to clamp a touch screen with a circular or other shapes, resulting in the problem of poor adaptability of the clamp.

[0007] In view of the defects in the prior art such as those mentioned above, we have designed a multifunctional fixture for touch screen processing. Utility Model Content

[0008] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution that can solve the above-mentioned problems.

[0011] As a further solution of the utility model: a limiting slide rod is also connected through the interior of the fixed plate and at positions on both sides of the adjusting screw rod. One end of the limiting slide rod is fixed to the movable plate, and a baffle is fixed to the other end.

[0012] As a further solution of the utility model: one end of the adjusting screw is rotatably connected to the movable plate, and the other end is fixed with an adjusting handle.

[0013] As a further solution of the utility model: the servo motor 1 is installed at the bottom of the fixed block, and the power output shaft of the servo motor 1 movably penetrates into the interior of the fixed block and is fixedly connected to the bottom of the rotating column.

[0014] As a further solution of the utility model: the limit plate is rotatably connected with the power output shaft of the cylinder, the limit plate is made of rubber, and the position of the limit plate corresponds to the rubber pad on the top of the rotating table.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. In the present application, the touch screen can be placed on the rubber pad through the designed structures such as the rotating table, rotating column, supporting plate, cylinder and limit plate, and the touch screen can be pressed down by the limit plate to achieve the clamping effect of the touch screen in the up and down directions, so that the touch screen can be driven to rotate in coordination with the rotation of the rotating table, which is convenient for the staff to process the touch screen in all directions, and there is no blocking structure on the side of the touch screen, which can facilitate the operation of the staff. When the touch screen rotates, the staff can achieve the purpose of processing different positions of the touch screen at the same workstation. Compared with the prior art, the side processing of the touch screen will be blocked and it is difficult to achieve the rotation of the touch screen to facilitate the processing of the staff, which has better convenience.

When the rotating column 7 rotates, it can synchronously drive the support plate 8 and the cylinder 9 to rotate to the top of the rotating table 2.

[0026] In this embodiment, a support frame 12 is fixed to the bottom of the processing seat 1, a servo motor 13 is installed on the support frame 12, a driving gear 14 is installed on the power output shaft of the servo motor 13, a driven gear 15 is meshed on the driving gear 14, a connecting shaft 16 is fixed in the middle of the driven gear 15, and the top of the connecting shaft 16 movably passes through the processing seat 1 and is fixed at the center position of the bottom of the rotating table 2.

[0027] Specifically, the support frame 12 can play a role in installing and fixing the servo motor 13. When the power output shaft of the servo motor 13 drives the driving gear 14 to rotate, it can drive the driven gear 15 meshing with it to rotate, and finally use the connecting shaft 16 to drive the rotating table 2 to rotate.

[0028] In this embodiment, a limiting slide bar 17 is also connected through the interior of the fixed plate 401 and at positions on both sides of the adjusting screw 11. One end of the limiting slide bar 17 is fixed on the movable plate 402, and a baffle is fixed on the other end.

[0032] When the surface of the touch screen needs to be clamped:

[0033] The staff first places the touch screen on the rubber pad 3 on the top of the rotating table 2, and uses the rubber pad 3 to support the touch screen. Then, the adjusting screw 11 is turned, and one end of the adjusting screw 11 is used to push the movable plate 402, the return spring 403 and the rubber sheet 404 toward the side close to the side of the touch screen until the side of the rubber sheet 404 contacts the side of the touch screen. When the touch screen is square, the side of the touch screen contacts the entire rubber sheet 404 to squeeze the return spring 403, so that the touch screen is squeezed by the rebound effect of the return spring 403. , the effect of clamping firmly. When the touch screen is in other shapes, since the rubber sheet 404 is soft and there are multiple return springs 403 that do not fit each other, the touch screen will only squeeze the contact part with the rubber sheet 404, thereby achieving the effect of squeezing the touch screen of other shapes by the clamping component 4, so that the clamping component 4 can clamp the square or other shaped touch screen stably. When the two groups of clamping components 4 are clamped on both sides of the touch screen respectively, the touch screen is fixed, which is convenient for the staff to process the surface of the touch screen;

[0034] When the side of the touch screen needs to be clamped:

[0036] Then, the servo motor 2 13 is started, and the power output shaft of the servo motor 2 13 drives the driving gear 14 to rotate, and the driving gear 14 drives the driven gear 15 to rotate. After the driven gear 15 rotates, the connecting shaft 16 is used to drive the entire rotating table 2 to rotate, thereby driving the touch screen on the rotating table 2 to rotate synchronously. When the touch screen rotates, the staff can process the side and surface of the touch screen at the same workstation.
