[0020] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 3 As shown, this utility model discloses a first embodiment of a panel polishing machine assembly, including a polishing head unit 1, a polishing head support 2, and a rotary drive mechanism 3. The polishing head units 1 are arranged in an array on the polishing head support 2, and each polishing head unit 1 is wound around the same transmission belt 4 or transmission chain. The rotary drive mechanism 3 drives at least one of the polishing head units 1 to drive each polishing head unit 1 to rotate synchronously.

[0022] In this embodiment, grinding head units 1 are arrayed on the grinding head support 2, and the rotary drive mechanism 3 is connected to each of the grinding head units 1 through the same transmission belt 4 or transmission chain, so as to realize synchronous drive of each grinding head unit 1 to rotate. The grinding head units 1 of the grinding assembly are evenly distributed and have consistent action steps, resulting in good grinding uniformity, which can be applied to high-precision processing of small-sized panels.

[0023] Specifically, the grinding head support 2 includes a sliding plate 21, a grinding head mounting plate 22 disposed below the sliding plate 21, and a support member 23 connected to the sliding plate 21 and the grinding head mounting plate 22. In this embodiment, the support member 23 includes a support column and a connecting plate. The driving space formed between the sliding plate 21 and the grinding head mounting plate 22 is in which the rotary drive mechanism 3 and the transmission belt 4 are both disposed. The grinding head unit 1 is rotatably disposed on the grinding head mounting plate 22 and extends downward from the driving space to grind the panel below.

[0024] The rotary drive mechanism 3 in this embodiment includes a second drive motor, a driving pulley, and a driven pulley. The second drive motor is fixed to the slide plate 21. The driving pulley is located at the power output end of the second drive motor. The driven pulley is coaxially connected to one of the grinding head units 1 and is connected to the driving pulley via a transmission belt. Alternatively, the rotary drive mechanism 3 can be a geared motor, with its power output end connected to one of the grinding head units 1. In this embodiment, the rotary drive mechanism 3 drives one of the grinding head units 1 to rotate the other grinding head units 1.

[0025] In this embodiment, multiple grinding head units 1 are arranged in a first preset direction. The transmission belt 4 is arranged in an S-shape in the first preset direction to wrap around the grinding head units 1 arranged in the first preset direction. The rotation directions of two adjacent grinding head units 1 in the first preset direction are opposite, which helps to improve the grinding uniformity.

[0026] In this embodiment, the grinding head unit 1 is arranged in two rows in a second preset direction perpendicular to the first preset direction. The transmission belt 4 is sleeved on the two rows of grinding head units 1, and the transmission belt 4 is arranged in an S-shape in the first preset direction. While improving the grinding uniformity, the winding path of the transmission belt 4 is simple, the transmission belt 4 has more uniform contact with the grinding head unit 1, and the entire transmission belt 4 is easier to maintain a uniform tension, ensuring the reliability of synchronous transmission.

[0027] The grinding assembly in this embodiment also includes a slide block 5 and a swing drive mechanism 6. The grinding head support 2 is connected to the slide block 5, specifically, the slide plate 21 and the slide block 5 slide in a first preset direction. The swing drive mechanism 6 is used to drive the slide block 5 to slide back and forth in the first preset direction. Since the slide plate 21 and the slide block 5 slide in the first preset direction, when the slide block 5 slides back and forth in the first preset direction, the slide plate 21 will swing accordingly, and the grinding head unit 1 mounted on the grinding head support 2 will swing accordingly in the first preset direction, further improving the grinding uniformity.

[0028] The swing drive mechanism 6 specifically includes a first drive motor 61, an eccentric block 62, and a rocker arm 63. The first drive motor 61 is connected to the frame 7. A guide rail slider assembly 8 is provided between the frame 7 and the slide block 5. The guide rail slider assembly 8 extends along a first preset direction. The eccentric block 62 is located at the drive end of the first drive motor 61. The two ends of the rocker arm 63 are rotatably connected to the eccentric block 62 and the slide block 5, respectively. In this embodiment, the guide rail slider assembly 8 includes a slider on the frame 7 and a guide rail on the top of the slide block 5. The guide rail extends along the first preset direction, and the slider slides in cooperation with the guide rail. When the eccentric block 62 on the first drive motor 61 drives the rocker arm 63 to swing, the slide block 5 slides back and forth slightly relative to the frame 7 along the first preset direction.

[0029] This embodiment also includes a grinding head cover plate 9 and a guide rail cover 10. The grinding head cover plate 9 is connected to the slide block 5 to prevent external dust and other impurities from contaminating the rotary drive mechanism 3. The guide rail cover 10 is connected to the frame 7, and the guide rail slider assembly 8 is surrounded by the guide rail cover 10 to prevent impurities from entering the guide rail slider assembly 8 and the swing drive mechanism 6, thus preventing drive jamming due to impurity intrusion.

[0030] In this embodiment, rollers 213 are provided on both opposite outer side walls of the slide plate 21. The bottom of the slide block 5 has an opening, and grooves 51 adapted to the rollers 213 are provided on both sides of the opening. The grooves 51 extend along a first preset direction, and the wheel surface of the rollers 213 abuts against the grooves 51. When the slide block 5 slides back and forth in the first preset direction, the rollers 213 on the outer side walls of the slide plate 21 roll on the grooves 51, making the movement of the slide plate 21 relative to the slide block 5 smoother. The rollers 213 on the slide plate 21 are housed in the grooves 51 of the slide block 5, and the grinding head cover plate 9 is connected to the slide block 5, helping to prevent impurities from entering and affecting the smooth operation of the rollers 213 relative to the slide block 5.

[0031] The slide plate 21 specifically includes a main body 211 and an end plate 212. The main body 211 extends into the opening, and the rollers 213 are disposed on the two opposite outer side walls of the main body 211. The end plate 212 is disposed at the end of the main body 211 and protrudes from the opposite two outer side walls of the main body 211 to prevent the slide plate 21 from falling off the end of the slide block 5.

[0032] Furthermore, the bottom of the end plate 212 is folded downwards, and a limiting member 214 is provided at the bottom of the end plate 212. The limiting member 214 extends from the top surface of the end plate 212 towards the slide block 5 to limit the vertical movement of the slide plate 21. The length of the limiting member 214 extending towards the top surface of the end plate 212 is adjustable to facilitate the assembly of the slide plate 21 and the slide block 5. At the same time, the top surface of the bottom wall of the slide groove 51 makes rolling contact with the roller 213, and the bottom surface of the bottom wall of the slide groove 51 approaches or even slides into contact with the locking member, preventing the slide plate 21 from jumping relative to the slide block 5. This makes the grinding head unit 1 grind the panel more smoothly and helps to improve the grinding quality of small-sized panels.

[0033] The above-disclosed embodiment is merely a preferred embodiment of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
