[0002] A Mini LED backlight substrate grinding machine is a device specifically used for processing and grinding Mini LED backlight substrates. Since Mini LED backlight substrates need to achieve a certain flatness, smoothness, and dimensional accuracy during the manufacturing process, special grinding machines are required for processing. However, during the clamping and grinding process of the LED backlight substrate by the existing grinding machines, due to poor clamping effect, the backlight substrate will move or shake, making it difficult to ensure the accuracy and consistency of grinding. Secondly, Mini LED backlight substrates may have different sizes, shapes, and material properties, and some clamping devices do not have adaptability, thus unable to adjust and cannot adapt to substrates of different specifications. Content of the Utility Model
[0003] The main purpose of the utility model is to provide a clamping device for a Mini LED backlight substrate grinding machine, which can effectively solve the problems in the background technique.

During the movement of the fixed block, it drives the installation frame and the grinding device connected to it to move as a whole, thereby realizing the adjustment of the grinding position. The sliding connection between the fixed block and the inner upper wall of the reinforcement arm plays a guiding and stabilizing role, ensuring the accuracy and stability of the linear movement of the fixed block.
[0009] Preferably, the lifting device includes a cylinder, the cylinder is fixedly connected to the lower end of the base plate, the output end of the cylinder penetrates through the left part of the lower end of the base plate and is fixedly connected to a bottom plate, a limiting block is fixedly connected to the rear part of the left end of the bottom plate, a fixed frame is fixedly connected to the upper end of the bottom plate, a through limiting rectangular opening is formed in the middle of the upper end of the fixed frame, a clamping substrate structure is fixedly connected to the middle of the right end of the fixed frame, and the upper part of the clamping substrate structure is slidably connected to the limiting rectangular opening.
[0010] By adopting the above technical solution: the limiting block can limit the moving range of the bottom plate, preventing it from moving excessively or deviating from the normal position.

The clamping substrate structure is used to clamp and fix the substrate to be operated and can slide along the limiting rectangular opening on the fixed frame to adapt to different working requirements.
[0011] Preferably, the limiting block is slidably connected in a limiting groove.
[0012] By adopting the above technical solution: the cooperation between the limiting block and the limiting groove is to further limit the moving direction and range of the bottom plate, ensuring that the bottom plate can only move smoothly and accurately up and down along the established straight line direction under the push of the cylinder, avoiding shaking, deviation or other unstable situations, thereby ensuring the accuracy and stability of the operation of the entire lifting device.

[0014] By adopting the above technical solution: the rotation of the reverse threaded rod makes the two connecting round blocks approach or move away from each other, thereby driving the two iron frame bases to move, realizing the preliminary adjustment and positioning of the left and right positions of the backlight substrate body. The electric push rod can drive the magnetic pressing plate to move up and down, realizing the pressing and loosening of the backlight substrate body. The magnetic pressing plate acts jointly through magnetic force and pressure to firmly clamp the backlight substrate body, ensuring its stability during processing or operation. The backlight substrate body is closely attached to the upper end surface of the fixed frame, providing a stable support basis for the substrate.
[0015] Preferably, the two iron frame bases are distributed in a left-right mirror image. The two magnetic pressing plates are respectively slidably connected to the two iron frame bases through two chute openings. The two magnetic pressing plates are respectively magnetically adsorbed and connected to the two iron frame bases. The backlight substrate body is located between the magnetic pressing plate and the iron frame base. The backlight substrate body is directly below the grinding machine and is vertically distributed.
[0016] By adopting the above technical solution: the two iron frame bases are distributed in a left-right mirror image, which can symmetrically clamp and position the backlight substrate body from the left and right sides, ensuring the balance and stability of the clamping.

By adjusting the distance between the two iron frame bases through the cooperation of the positive and reverse threaded rod and the connecting round block, diverse clamping requirements can be met. The electric push rod pushes the magnetic pressing plate to be magnetically adsorbed to the iron frame base, clamping the backlight substrate body from the upper and lower sides to ensure that it will not loosen or shift during processing, improving the processing accuracy and quality. Therefore, the stable clamping method and accurate positioning contribute to improving the grinding efficiency of the grinding machine on the backlight substrate body and reducing processing errors and time waste caused by substrate shaking.

[0028] Please refer to Figures 1-4 , the present utility model provides a technical solution:
[0029] A clamping device for a Mini LED backlight substrate grinding machine, comprising a base plate 1. Support legs 2 are fixedly connected to the peripheries of the lower end of the base plate 1. A reinforcing arm 3 is fixedly connected to the left part of the upper end of the base plate 1. A limiting groove 4 is formed in the lower part of the inner left wall of the reinforcing arm 3. A control keyboard 5 is fixedly connected to the middle part of the upper end of the reinforcing arm 3. An adjusting grinding pin structure 6 is threadedly and movably connected to the right end of the reinforcing arm 3. The left part of the adjusting grinding pin structure 6 is located in the upper part of the inner part of the reinforcing arm 3. A lifting device 7 is fixedly connected to the left part of the lower end of the base plate 1. The lifting device 7 is slidably connected to the limiting groove 4.
[0030] In this embodiment, the adjusting grinding pin structure 6 includes a turning handle 61. A screw rod 62 is fixedly connected to the left end of the turning handle 61. The left end of the screw rod 62 is movably connected to the reinforcing arm 3 through a bearing. A fixing block 63 is threadedly and movably connected to the outer surface of the screw rod 62. A mounting frame 64 is fixedly connected to the lower end of the fixing block 63. A grinding device 65 is fixedly connected to the lower part of the front end of the mounting frame 64. The rear part of the grinding device 65 is located inside the mounting frame 64. The upper end of the fixing block 63 is slidably connected to the middle part of the inner upper wall of the reinforcing arm 3. The turning handle 61 is threadedly and movably connected to the lower part of the right end of the reinforcing arm 3. The lifting device 7 includes a cylinder 71. The cylinder 71 is fixedly connected to the lower end of the base plate 1. The output end of the cylinder 71 penetrates through the left part of the lower end of the base plate 1 and is fixedly connected to a bottom plate 72. A limiting block 73 is fixedly connected to the rear part of the left end of the bottom plate 72. A fixing frame 74 is fixedly connected to the upper end of the bottom plate 72. A through limiting rectangular opening 75 is formed in the middle part of the upper end of the fixing frame 74. A clamping substrate structure 76 is fixedly connected to the middle part of the right end of the fixing frame 74. The upper part of the clamping substrate structure 76 is slidably connected to the limiting rectangular opening 75. The limiting block 73 is slidably connected inside the limiting groove 4.
[0031] Through the above solution: The operator manually rotates the turning handle 61 to drive the screw rod 62 to rotate. Since the screw rod 62 is threadedly and movably connected to the fixed block 63, and the upper end of the fixed block 63 is slidably connected to the middle part of the inner upper wall of the reinforcement arm 3, the rotation of the fixed block 63 is restricted, so that the fixed block 63 moves in a horizontal straight line along the screw rod 62. The movement of the fixed block 63 drives the mounting frame 64 connected to its lower end to move horizontally, so that the grinder 65 fixedly connected to the lower part of the front end of the mounting frame 64 can adjust its position in the horizontal direction and can adapt to different grinding requirements.
[0032] In this embodiment, the clamping substrate structure 76 includes a driver 761. The driver 761 is fixedly connected to the right end of the fixed frame 74. The output end of the driver 761 penetrates through the middle part of the right end of the fixed frame 74 and is fixedly connected with a positive and negative threaded rod 762. The left end of the positive and negative threaded rod 762 is movably connected to the fixed frame 74 through a bearing. Both the left part and the right part of the outer surface of the positive and negative threaded rod 762 are threadedly and movably connected with connecting round blocks 763. The upper parts of the outer surfaces of the two connecting round blocks 763 are fixedly connected with iron frame seats 764. The upper parts of the two iron frame seats 764 jointly pass through the limiting rectangular opening 75. Chute openings 765 are formed at one ends of the two iron frame seats 764 close to each other. Electric push rods 766 are fixedly connected to the upper ends of the two iron frame seats 764. The output ends of the two electric push rods 766 respectively penetrate through the upper ends of the iron frame seats 764 and are fixedly connected with magnetic pressing plates 767. A backlight substrate body 768 is placed between the two magnetic pressing plates 767. The backlight substrate body 768 is in close contact with the upper end surface of the fixed frame 74. The two iron frame seats 764 are distributed in a left-right mirror image. The two magnetic pressing plates 767 are respectively slidably connected with the two iron frame seats 764 through the two chute openings 765. The two magnetic pressing plates 767 are respectively magnetically adsorbed and connected with the two iron frame seats 764. The backlight substrate body 768 is located between the magnetic pressing plates 767 and the iron frame seats 764. The backlight substrate body 768 is located directly below the grinder 65 and is vertically distributed.
[0033] Through the above solution: First, start the operation of the driver 761 by controlling the keyboard 5. The output end of the driver 761 drives the rotation of the left - right threaded rod 762. Due to the special structure of the left - right threaded rod 762, the thread directions on the left and right parts of its outer surface are opposite, enabling the two connecting round blocks 763 to move towards or away from each other according to the thread direction. Thus, the movement of the connecting round blocks 763 can synchronously drive the iron frame base 764 fixedly connected to them, and the distance between the two iron frame bases 764 can be adjusted to adapt to the backlight substrate body 768 of different lengths. Then, start the operation of the electric push rod 766 by controlling the keyboard 5. The output end of the electric push rod 766 pushes the magnetic pressing plate 767 to move downward along the chute opening 765. Since the magnetic pressing plate 767 is magnetically adsorbed and connected to the iron frame base 764, the clamping force can be enhanced, thereby firmly clamping the backlight substrate body 768 between the magnetic pressing plate 767 and the iron frame base 764. Finally, after the backlight substrate body 768 is clamped and fixed, adjust the position of the grinding and polishing structure 6 to adjust the position of the grinder 65, and adjust the height of the backlight substrate body 768 by the lifting device 7, so that the grinder 65 can perform grinding processing on the backlight substrate body 768 located directly below it and vertically distributed.
[0034] It should be noted that the present utility model is a clamping device for a Mini - LED backlight substrate grinding machine. During use, it can achieve precise grinding for backlight substrate bodies 768 of different specifications. First, start the operation of the driver 761 by controlling the keyboard 5. The driver 761 can drive the rotation of the left - right threaded rod 762, enabling the two connecting round blocks 763 to drive the iron frame bases 764 to move towards or away from each other, thereby adjusting the distance between the two iron frame bases 764 to adapt to the length of the backlight substrate body 768. Then, start the electric push rod 766 to push the magnetic pressing plate 767 to move downward along the chute opening 765. The magnetic pressing plate 767 is magnetically adsorbed to the iron frame base 764, clamping and fixing the backlight substrate body 768 from the upper and lower sides. Next, during the grinding process, the bottom plate 72 is pushed upward by the cylinder 71, so that the clamped backlight substrate body 768 reaches an appropriate grinding height. The limit block 73 slides in the limit groove 4 to ensure the stability and verticality of the rising process. At the same time, the operator manually rotates the turning handle 61 to drive the screw rod 62 to rotate, so that the fixed block 63 drives the mounting frame 64 and the grinder 65 to move horizontally to an appropriate position. Since the backlight substrate body 768 is firmly clamped and its position is precisely adjusted during grinding, it will not move under the grinding of the grinder 65, achieving more efficient and stable grinding.

Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the descriptions in the specification only illustrate the principles of the present utility model.
