Abstract
Description
Technical Field
[0001] This utility model relates to the field of machinery, and in particular to a quick-release structure for grinding heads used in electronic terminal polishing equipment. Background Technology
[0002] The glass sheet involved in this utility model is mainly used in electronic terminals, especially mobile phones, tablets and other electronic products. The polishing equipment is mainly connected to the previous production process. After the previous production process produces the glass sheet, its surface needs to be polished. After the glass sheet is polished by the grinding wheel, it is transferred to the storage frame by the transfer mechanism.
[0003] The grinding disc mechanism mainly consists of a grinding head and a grinding mat fixed on it. Currently, the grinding head and the grinding mat are directly glued together. When the grinding mat wears down to a certain extent, it needs to be replaced. However, the current replacement method is very troublesome and requires manual removal. This is not only time-consuming, but also difficult and inefficient. Each replacement of the grinding mat takes a whole day or even longer, which seriously limits production efficiency. Therefore, it is urgent to improve the automatic calibration mechanism of the polishing equipment. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a quick-release structure for grinding heads that can be quickly replaced without stopping the machine to remove the grinding head base and is low in cost.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A quick-release structure for the polishing head of a polishing equipment includes: a mounting base; a drive mechanism, the drive mechanism comprising a first drive device, a rotating shaft, and a mounting plate; the first drive device is mounted on the mounting base; the rotating shaft is connected to the first drive device; and the mounting plate is connected to the rotating shaft; and a polishing head assembly, the polishing head assembly being disposed on the mounting plate and rotatable with the rotating shaft driven by the first drive device, comprising a polishing head base and a polishing mat, the polishing mat being detachably mounted on the polishing head base via a connecting structure. The polishing head base is preferably made of rigid sponge.
[0006] Furthermore, the connection structure includes Velcro, and the grinding head base includes a grinding surface and a side surface. The hook or loop side of the Velcro is disposed on the grinding surface and the side surface. When the grinding mat is laid on the grinding head base, the grinding mat covers the grinding surface and the side surface of the grinding head base, and the hook and loop sides of the Velcro are attached to each other. The Velcro structure is simple and is one of the better connection structures. It is easy to install and can greatly reduce the cost of the connection structure.
[0007] Furthermore, to make the Velcro installation more secure, hook or loop surfaces of Velcro are provided on the grinding surface, sides and top surface of the grinding head base. When the grinding carpet is laid on the grinding head base, the grinding carpet covers the grinding surface, sides and top surface of the grinding head base.
[0008] Furthermore, the grinding head base includes a grinding surface, a side surface, and a top surface. The connecting structure includes several lugs and several pull posts. The lugs are arranged along the periphery of the grinding carpet, and the pull posts are arranged along the periphery of the top surface of the grinding head base. When the grinding carpet covers the grinding head base, the lugs are hung on the pull posts. The combination of lugs and pull posts achieves another connection structure, which has better stability.
[0009] Furthermore, to achieve a more robust connection, the Velcro and pull tab / pull post connection structures are combined. Specifically, the grinding head base also includes a top surface, and the connection structure includes several pull tabs and several pull posts. The pull tabs are arranged along the periphery of the grinding carpet, and the pull posts are arranged along the periphery of the top surface of the grinding head base. When the grinding carpet is laid on the grinding head base, the grinding carpet covers the grinding surface and sides of the grinding head base, and the pull tabs are hung on the pull posts.
[0010] Furthermore, in order to enable the entire grinding head structure to have a lifting function and facilitate the replacement of the grinding mat later, the mounting base is configured to include a fixed base, a second drive device, and a movable mounting plate. The second drive device is mounted on the fixed mounting base, and the movable mounting plate is mounted on the fixed base via a slide rail assembly and is conventionally connected to the drive shaft of the second drive device. The second drive device can drive the movable mounting plate to move up and down along the length direction of the fixed base.
[0011] Compared with the prior art, this utility model sets the grinding carpet and grinding head base as a detachable structure, so that the grinding carpet can be quickly disassembled and replaced after wear, which greatly saves the time-consuming and labor-intensive disassembly labor cost, improves the replacement speed and production efficiency, and at the same time uses the connection structure of pull ears and / or Velcro to make the assembly of the grinding carpet and grinding head base more firm and stable.

[0014] See appendix Figure 1-3The quick-release structure for the polishing head of the polishing equipment includes: a mounting base 1, a drive mechanism 2, the drive mechanism 2 including a first drive device 21, a rotating shaft 22, and a mounting plate 23, the first drive device 21 being mounted on the mounting base 1, the rotating shaft 22 being connected to the first drive device 21, and the mounting plate 23 being connected to the rotating shaft 22; and a polishing head assembly 3, the polishing head assembly 3 being disposed on the mounting plate 23 and rotatable with the first drive device 21 driving the rotating shaft 22, comprising a polishing head base 31 and a polishing mat 32, the polishing mat 32 being detachably mounted on the polishing head base 31 via a connecting structure 4. The polishing head base 31 is preferably made of rigid sponge.
[0015] The aforementioned connection structure 4 is a hook and loop fastener. The grinding head base 31 includes a grinding surface 311 and a side surface 312. The hook side 41 or the loop side 42 of the hook and loop fastener is disposed on the grinding surface 311 and the side surface 312.

The hook side 41 and the loop side 42 of the hook and loop fastener fit together. The hook and loop fastener structure is simple and is one of the better connection structures 4. It is easy to install and can greatly reduce the cost of the connection structure 4.
[0016] As a preferred embodiment, in order to enable the entire grinding head structure to have a lifting function and facilitate the replacement of the grinding mat 32 later, the mounting base 1 is configured to include a fixed base 11, a second drive device 12, and a movable mounting plate 13. The second drive device 12 is mounted on the fixed mounting base 1, and the movable mounting plate 13 is mounted on the fixed base 11 via a slide rail assembly and is conventionally connected to the drive shaft of the second drive device 12. The second drive device 12 can drive the movable mounting plate 13 to move up and down along the length direction of the fixed base 11. Example
