[0004] However, the current machining center fixture for processing thinner coating fixtures has the following problems: it cannot use the spring force of the clamping plate to clamp and fix substrates of different thicknesses, which makes the clamping device unable to adapt to substrates of different thicknesses and cannot enhance the performance of the clamping device. Therefore, we propose to prepare a center-free coating fixture. Utility Model Content

[0009] Preferably, the action groove is located on the movement trajectory of the slider, the slider is slidably connected to the inner wall of the action groove, and the slider is fixedly connected to the side of the clamping plate. This design is beneficial for the clamping plate to clamp the substrate.

[0011] Preferably, the top of the clamp is provided with a slot, and one end of a force spring is fixedly connected to the inner wall of the slot. The end of the force spring away from the inner wall of the slot is fixedly connected to a block. This design allows the block to slide on the inner wall of the slot by the elastic force of the force spring.

[0012] Preferably, the slot is located on the movement trajectory of the card block, the card block is slidably connected to the inner wall of the slot, and there are two card blocks, which are symmetrical about each other along the vertical center of the support plate.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-4As shown, a central film-free coating fixture is prepared, including a support plate 1 and a fixed plate 2. The fixed plate 2 is fixedly connected to the top of the support plate 1, and a groove 3 is provided on the top of the support plate 1. A clamping device 4 is provided on the side of the fixed plate 2. The clamping device 4 includes an electric telescopic rod 41. The electric telescopic rod 41 is provided on the side of the fixed plate 2. A fixed ring 42 is fixedly connected to the telescopic end of the electric telescopic rod 41. A connecting plate 43 is fixedly connected to the circumferential surface of the fixed ring 42. A rotating shaft 44 is rotatably connected to the side of the connecting plate 43. A force-bearing rod 45 is fixedly connected to the circumferential surface of the rotating shaft 44. A rectangular groove 46 is provided on the top of the support plate 1. A sliding rod 47 is slidably connected to the inner wall of the rectangular groove 46. A clamping plate 48 is provided on the side of the sliding rod 47.

[0026] A receiving plate 49 is fixedly connected to the side of the slide rod 47, and a rotating rod 410 is rotatably connected to the side of the receiving plate 49. An action groove 411 is opened on the side of the slide rod 47, and one end of a spring 412 is fixedly connected to the inner wall of the action groove 411. A slider 413 is fixedly connected to the end of the spring 412 away from the action groove 411. This design is beneficial to the slider 413 being able to drive the clamping plate 48 to move.

[0027] The action groove 411 is located on the movement trajectory of the slider 413. The slider 413 is slidably connected to the inner wall of the action groove 411. The slider 413 is fixedly connected to the side of the clamping plate 48. This design is beneficial for the clamping plate 48 to clamp the substrate.

[0028] Based on the above structure, when the operator needs to clamp the substrate, the external power is turned on, causing the electric telescopic rod 41 to start. This forces the fixing ring 42 to retract along with the electric telescopic rod 41. When the fixing ring 42 retracts, it drives the connecting plate 43 and the rotating shaft 44 to retract, forcing the force-bearing rod 45 to undergo arc-shaped motion on the circumference of the rotating shaft 44. When the force-bearing rod 45 undergoes arc-shaped motion, the force-bearing rod 45 exerts force on the sliding rod 47 through the rotating rod 410, forcing the sliding rod 47 to undergo force in the action groove 41. 1. Slide on the inner wall, thereby forcing the clamping plate 48 to move towards the center of the groove 3. The clamping plate 48 can clamp and fix the substrate placed inside the groove 3. When the clamping plate 48 moves, the operator can pull the clamping plate 48, so that the clamping plate 48 is subjected to force through the slider 413 and the elastic force of the spring 412 to clamp and fix substrates of different thicknesses. This allows the clamping device 4 to adapt to substrates of different thicknesses, achieving the clamping effect and enhancing the performance of the clamping device 4.

[0029] like Figure 5As shown, an auxiliary device 5 is provided on the side of the clamping plate 48. The auxiliary device 5 includes an auxiliary groove 51, which is opened on the top of the clamping plate 48. A moving rod 52 is slidably connected to the inner wall of the auxiliary groove 51. A toggle rod 53 is fixedly connected to the top of the moving rod 52. A wiping plate assembly 54 is fixedly connected to the side of the toggle rod 53. This design is beneficial to the toggle rod 53 moving to drive the moving rod 52.

[0030] The top of the clamping plate 48 is provided with a slot 55. One end of a force spring 56 is fixedly connected to the inner wall of the slot 55. A locking block 57 is fixedly connected to the end of the force spring 56 away from the inner wall of the slot 55. This design is conducive to the locking block 57 sliding on the inner wall of the slot 55 by the elastic force of the force spring 56.

[0031] The slot 55 is located on the movement trajectory of the block 57. The block 57 is slidably connected to the inner wall of the slot 55. There are two blocks 57, which are symmetrical about each other along the vertical center of the support plate 1. This design is conducive to the block 57 being able to be locked on the side of the lever 53.

[0032] The force-bearing rod 45 is fixedly connected to the circumferential surface of the rotating rod 410. There are two sliding rods 47, which are symmetrical about each other along the vertical center of the support plate 1. This design is conducive to the force-bearing rod 45 making arc-shaped movements through the rotating shaft 44 and the rotating rod 410.

[0033] According to the above structure, in the clamping device 4, before coating the substrate, it is necessary to ensure that the substrate surface is free of dust. Before clamping the substrate, the actuating rod 53 is activated, causing the actuating rod 53 to drive the moving rod 52 to slide on the inner wall of the auxiliary groove 51, causing the locking block 57 to lose force and retract into the groove 55. When the actuating rod 53 moves and no longer contacts the locking block 57, the locking block 57 loses the squeezing force and pops out through the force spring 56. The actuating rod 53 drives the moving rod 52 to move, so that the wiping plate assembly 54 can follow the moving rod 52 to wipe the dust on the substrate surface, ensuring that the substrate surface is free of dust before coating and ensuring the smooth progress of the coating work.

[0034] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
