Description

Technical Field

[0001] This utility model belongs to the field of grinding and processing technology, and relates to a device for grinding the surface of a conductive pin seat. Background Technology

[0002] Conductive pins, which are placed between two components to electrically connect the two components and thus allow conductivity between the two components, have traditionally been used in various fields or products, such as various portable electronic devices, such as mobile phones, small game consoles, small personal computers and PDAs. In order to achieve better electrical and mechanical connections, conductive pin seats are required to facilitate the installation of conductive pins. In the prior art, the surface of the conductive pin seat usually needs to be polished to obtain good surface precision.

[0003] Due to the small size of the conductive pin base, existing technologies use magnetic polishing for grinding. However, the magnetic polishing machine disclosed in patent application CN202122312793.9 uses a motor to drive a fixed plate and an electromagnet to rotate, which in turn moves the magnetic needles to polish the parts. At the same time, the vibration motor is controlled to drive the second and third housings to vibrate, thereby causing the magnetic needles and parts in the third housing to vibrate and polish. This achieves the goal of quick and easy grinding and polishing of parts, avoiding the time-consuming process of traditional magnetic polishing machines, improving the polishing efficiency of the polishing machine, making it more convenient and meeting people's needs.

[0004] However, the above-mentioned magnetic polishing machine has the following disadvantages: the parts are small and cannot be taken out in batches, requiring manual sorting, which is very inconvenient. To address this, we designed a conductive pin seat surface polishing device. Utility Model Content

A cover plate mounting seat is installed at one end of the supporting vertical rod. A cylinder cover plate is provided at the bottom end of the cover plate mounting seat. A screw-on guard is installed at the bottom end of the cylinder cover plate. The cylinder cover plate is movably connected to the conductive pin seat container via the screw-on guard, so that the conductive pin seat container is suspended in the inner cavity of the magnetic polishing inner liner. A pin seat hollow pad is provided at the bottom end of the conductive pin seat container.

[0010] In the aforementioned conductive pin seat surface grinding device, an adhesive block is provided on the wall of the drain pipe, and the adhesive block is bonded to one side of the outer cylinder.

[0011] In the aforementioned conductive pin seat surface grinding device, a spring limit button is provided at the top of the upright guide seat, and the spring limit button corresponds to the insertion hole on the outer surface of the supporting upright.

A pin seat hollow pad is set at the bottom of the conductive pin seat container, which allows the conductive pin seat to be separated from the abrasive after polishing. This enables the conductive pin seats to be removed in batches without the need for manual sorting, which is very convenient. An air pump is set on the side of the movable base, and an air pipe is installed at the output end of the air pump. The one-way air inlet of the air pipe is connected to the inner cavity of the outer cylinder, which is suitable for use with chemical polishing agents for polishing operations.

The cylinder cover plate 10 is movably connected to the conductive pin seat container 9 via the screw-on enclosure 11, so that the conductive pin seat container 9 is suspended in the inner cavity of the magnetic polishing inner liner 7. A pin seat hollow pad 16 is provided at the bottom end of the conductive pin seat container 9.

[0022] The above scheme is designed to separate the conductive pin seat and the abrasive (mainly small abrasives such as steel balls or steel needles; the pin seat hollow pad 16 has a sieve hole to screen the conductive pin seat and the abrasive), making it convenient to remove the conductive pin seats in batches.

[0023] Example 2: In order to adapt to the polishing operation of chemical polishing agent, an air pump 17 is provided on the side of the movable base 1. An air pipe 18 is installed at the output end of the air pump 17. The one-way air inlet end of the air pipe 18 is connected to the inner cavity of the outer cylinder 6.
