[0029] The present application will be further described in detail below through the accompanying drawings and examples.

[0030] Reference Figures 1 to 5The embodiment of the present application provides a wafer grinding head that is easy to disassemble, including a grinding head 1, a combination block 5 is fixedly installed on the top of the grinding head 1, a mounting component 2 is provided on the outside of the combination block 5, a fixing component 3 is provided on the top of the mounting component 2, and a rotating shaft 4 is provided on the top of the mounting component 2. The mounting component 2 includes a mounting block 21, an internal groove 22 is provided inside the mounting block 21, a mounting groove 26 is provided inside the mounting block 21, the combination block 5 is inserted into the mounting groove 26, a slot 25 is provided inside the combination block 5, a rack 23 is inserted into the slot 25, the outer end of the rack 23 movably passes through the side wall between the mounting groove 26 and the internal groove 22, and the rotating shaft 4 is fixedly mounted on the top of the mounting block 21.

[0031] A limit rod 24 is fixedly mounted on the outer inner wall of the mounting block 21 and inserted into the corresponding rack 23. A rotating rod 28 is rotatably connected to the inner bottom of the internal groove 22. A gear 27 is fixedly mounted on the top of the rotating rod 28 and meshes with the corresponding rack 23. A gear ring 29 is rotatably connected to the inner side wall of the internal groove 22, and each gear 27 is threaded onto the outer side of the gear ring 29.

[0032] In this embodiment, the rotation of the gear 27 can drive the gear ring 29 to rotate, and the rotation of the gear ring 29 can drive the multiple gears 27 on the outside to rotate synchronously. The synchronous rotation of the gear 27 can drive the multiple racks 23 on the outside to move synchronously inward or outward, and the externally arranged limit rod 24 can ensure that the rack 23 moves horizontally. By synchronously moving and plugging the multiple racks 23 into the slot 25, the combination block 5 can be fixed inside the mounting groove 26, thereby fixing the grinding head 1 to the bottom of the mounting block 21, thereby fixing the grinding head 1, and when disassembling, the rack 23 can be synchronously moved out of the slot 25 to release the fixation of the combination block 5, and the grinding head 1 can be directly removed, thereby achieving the effect of convenient installation and disassembly of the grinding head 1.

[0033] Reference Figures 1 to 5 In one aspect of this embodiment, the fixing assembly 3 includes a fixing rod 31, which is rotatably connected to the top of the gear 27, and the top of the fixing rod 31 movably passes through the top of the mounting block 21. A screw 32 is fixedly installed on the top of the fixing rod 31, and a hexagonal slot 33 is provided on the top of the screw 32.

[0034] A nut 34 is threaded onto the outer side of the screw rod 32 , and a friction plate 35 is fixedly mounted on the bottom of the nut 34 . The friction plate 35 is sleeved onto the outer side of the screw rod 32 and fits onto the top of the mounting block 21 .

[0035] In this embodiment, when the gear 27 needs to be rotated to disassemble the table grinding head 1, the nut 34 is loosened to remove the friction plate 35 from the mounting block 21, thereby releasing the fixation of the screw 32. The screw 32 is rotated through the hexagonal slot 33 using an Allen wrench. The rotation of the screw 32 drives the lower fixed rod 31 to rotate.

[0037] Working principle: The rotation of the gear 27 can drive the gear ring 29 to rotate, and the rotation of the gear ring 29 can drive the multiple gears 27 on the outside to rotate synchronously. The synchronous rotation of the gear 27 can drive the multiple racks 23 on the outside to move synchronously inward or outward, and the external limit rod 24 can ensure that the rack 23 moves horizontally. By synchronously moving multiple racks 23 and plugging them into the slot 25, the combination block 5 can be fixed in the installation groove 26, thereby fixing the grinding head 1 to the bottom of the mounting block 21, and fixing the grinding head 1. When disassembling, the rack 23 can be synchronously removed from the slot 25 to release the combination block. 5 is fixed, the grinding head 1 can be directly removed, thereby achieving the effect of convenient installation and disassembly of the grinding head 1; and when the gear 27 needs to be rotated for disassembling the grinding head 1, the nut 34 is loosened to remove the friction plate 35 from the mounting block 21, thereby releasing the fixation of the screw 32, and the screw 32 is rotated through the hexagonal slot 33 using an inner hexagonal wrench. The rotation of the screw 32 drives the lower fixed rod 31 to rotate, and the rotation of the fixed rod 31 drives the lower gear 27 to rotate, so that the synchronous movement of multiple racks 23 can be achieved, so that the grinding head 1 can be installed by rotating only one screw 32, ensuring the convenience of installation and disassembly.
