Electronic product silicon rubber shockproof anti-skid pad burr polishing device

Abstract

This utility model discloses a rough edge polishing device for silicone rubber shock-absorbing and anti-slip pads for electronic products, including a main body and a motor located inside the main body, which drives a rotating shaft located at the front end of the main body to rotate. A connecting plate is fixed at the front end of the rotating shaft. When installing the connecting piece and the rotating shaft, the handle is pulled outward so that the connecting rod is located inside the groove of the connecting piece. At the same time, the movement of the handle causes the circular plate to compress the stainless steel spring. At this time, the connecting plate can be inserted into the groove of the connecting piece, and the connecting rod enters the internal position of the through hole through the groove. Releasing the handle causes the stainless steel spring to release its elastic force, and the insert post is inserted into the internal position of the through hole. Since the diameter of the through hole is larger than the width of the through groove, the polishing disc is installed with the rotating shaft. This connection allows for quick disassembly and installation without the need for tools.

[0002] The burr removal device for silicone rubber shock-absorbing and anti-slip pads in electronic products is a device specifically designed to remove burrs and flash generated on the edges of silicone rubber shock-absorbing and anti-slip pads after molding, cutting, and other processing. It uses the high-speed rotation or reciprocating motion of the grinding head to uniformly grind away excess burrs on the edges. At the same time, the grinding parameters can be adjusted according to different specifications of anti-slip pads to ensure that the edges of the ground products are smooth and the dimensions are accurate. It avoids the problems of low efficiency and poor accuracy of manual grinding, and reduces damage to the silicone rubber body, ensuring that the shock-absorbing and anti-slip performance is not affected. It is widely used in the mass production and processing of electronic equipment accessories.

[0003] When using the burr-removing device for silicone rubber shock-absorbing and anti-slip pads for electronic products, the grinding disc and the rotating shaft are installed with bolts. Disassembly requires tools and takes too much time. Therefore, the market needs a new connection method to solve the current problems. Utility Model Content

[0013] Compared with the prior art, this utility model provides a rough edge polishing device for silicone rubber shock-absorbing and anti-slip pads for electronic products, which has the following beneficial effects:

[0014] 1. When installing the connector and the rotating shaft, pull the handle outward so that the connecting rod is positioned inside the groove of the connector. At the same time, the movement of the handle causes the circular plate to compress the stainless steel spring, accumulating compressive energy. At this time, the connecting plate can be inserted into the groove of the connector, and the connecting rod enters the internal position of the through hole through the slot. Releasing the handle allows the stainless steel spring to release its elastic force, and the insert post is inserted into the internal position of the through hole. Since the diameter of the through hole is larger than the width of the through slot, the grinding disc and the rotating shaft can be installed. This connection allows for quick disassembly and installation without the need for tools.

[0015] 2. When the insert pin is inserted into the inner position of the through hole, the external thread of the handle can be rotated to enter the inner position of the threaded hole. This prevents the insert pin from being dislodged from the through hole by centrifugal force when the shaft is rotating. Attached Figure Description

It includes a main body 1, a motor inside the main body 1 that drives a rotating shaft 8 located at the front end of the main body 1 to rotate, a connecting plate 9 fixed at the front end of the rotating shaft 8, a through groove 11 and a through hole 10 provided inside the connecting plate 9, a connector 7 installed at the front end of the rotating shaft 8 through the connecting plate 9, an insertion post 12 inserted into the inside of the connector 7, a connecting rod 14 fixed inside the insertion post 12, a circular plate 15 fixed at the other end of the connecting rod 14, a stainless steel spring 13 provided at the lower end of the circular plate 15, a handle 5 fixed at the outer end face of the insertion post 12 for controlling its movement, a grinding disc 6 provided at the lower part of the outer wall of the handle 5 and connected to a threaded hole 16 at the side end face of the connector 7.

[0025] When in use, the operator holds the handle 3 with one hand, connects the main body 1 to the power supply, and the internal motor works to drive the rotating shaft 8 to rotate. The rotating shaft 8 drives the grinding disc 6 to rotate at high speed. The rotating grinding disc 6 is aligned with the silicone rubber shock-absorbing and anti-slip pad where the burrs need to be treated. The friction between the surface of the grinding disc 6 and the burrs is used to gradually grind and remove the burrs.

[0026] like Figure 2 and Figure 4 As shown, when the motor inside the main body 1 is working, it dissipates heat through the heat dissipation holes 2 located on both sides of the main body 1. A handle 3 is provided at the lower end of the main body 1, and a button 4 is provided at the upper front end of the handle 3. A grinding disc 6 is provided at the front end of the connector 7.
