[0002] The polytetrafluoroethylene glass fiber substrate (commonly known as the polytetrafluoroethylene glass fiber board) is a high-performance composite material, which is formed by alternately pressing and thermally curing a polytetrafluoroethylene (PTFE) emulsion as a raw material and a glass fiber cloth layer. After the thermal curing treatment, the polytetrafluoroethylene glass fiber board can be cut and processed to make products of different shapes and sizes (such as electronic components, high-temperature hot plates, etc.). Common processing methods include punching, drilling, cutting, bending, etc.

[0003] In the production process of the polytetrafluoroethylene glass fiber board, it is necessary to punch holes in its wall body through an automatic punching jig to meet the later assembly requirements. When the drill bit of the punching jig impacts the glass fiber board, a large amount of dust will be generated. The glass fiber dust contains substances that are irritating to the human skin and respiratory system. Being placed in such an environment for a long time will cause serious harm to the human body.

[0026] An embodiment of the present utility model discloses a punching jig for a polytetrafluoroethylene fiberglass substrate.

[0027] The present utility model provides a punching jig for a polytetrafluoroethylene fiberglass substrate as shown in Figures 1-4 which includes an L-shaped base 1. A loading table 2 is slidably connected to the outer wall of the L-shaped base 1. A substrate main body 3 is placed on the loading table 2. A working box 4 is fixedly installed on the outer wall of the L-shaped base 1, and the working box 4 is located above the loading table 2. A driving motor 5 is installed on the top of the working box 4. The output end of the driving motor 5 is connected to a shaft rod 6, and the shaft rod 6 is located inside the working box 4. A drill bit 7 is fixedly installed at the bottom end of the shaft rod 6.

[0028] A rotating cylinder 8 is fixedly sleeved on the outer side of the shaft rod 6. A lifting plate 9 is slidably sleeved on the outer side of the rotating cylinder 8. A slide rail groove 10 is formed on the outer wall of the rotating cylinder 8, and the track of the slide rail groove 10 is in a "W" shape. A piston 12 is connected to the bottom of the lifting plate 9 through a connecting rod 11, and the piston 12 is annular. A dynamic seal ring 13 is provided at the connection between the piston 12 and the shaft rod 6.

[0029] Specifically, while the driving motor 5 drives the shaft rod 6 to rotate to achieve the punching action of the drill bit 7, the rotating cylinder 8 can also rotate synchronously around the axis of the shaft rod 6 without the need for an additional air pump or other power source; every time the rotating cylinder 8 rotates one circle, the lifting plate 9 reciprocates up and down twice along the slide rail groove 10. Under the connection action of the connecting rod 11, a large amount of dust generated during the punching of the drill bit 7 is collected by the piston 12, reducing or avoiding harm to the operator.

[0030] To improve the functionality of the device, as Figure 3 、 Figure 4 shown, sliding rods 14 are symmetrically arranged on both sides of the lifting plate 9, and the sliding rods 14 movably penetrate through the wall of the lifting plate 9; an elastic member 15 is arranged between the outer wall of the lifting plate 9 and the inner wall of the working box 4, and the elastic member 15 is sleeved outside the sliding rod 14; an installation rod 16 is connected to the inner wall of the lifting plate 9, and the end of the installation rod 16 away from the lifting plate 9 is slidably connected in the slide rail groove 10.

[0031] Specifically, the elastic member 15 can be selected as a spring according to the actual situation, which is convenient for the lifting plate 9 to quickly move downward and reset after moving upward; under the limiting action of the sliding rod 14, the lifting plate 9 can only move vertically along the axis of the sliding rod 14, avoiding the lifting plate 9 from shifting and shaking during movement, and the elastic member 15 is compressed when the lifting plate 9 moves upward.

[0032] And to improve the practicality of the device, as Figure 1 shown, an electric push rod 17 is fixedly installed on the L-shaped base 1, the telescopic end of the electric push rod 17 is connected to the bottom of the loading platform 2, and a receiving groove 18 for collecting waste is annularly arranged around the loading platform 2; a dust collection hood 19 is fixedly installed at the bottom of the working box 4, and the dust collection hood 19 is adapted to the shape of the receiving groove 18; an activity cavity for the piston 12 to move up and down is provided in the dust collection hood 19, and a cloth bag 20 for collecting dust is installed on the outer wall of the dust collection hood 19.

[0033] Specifically, by starting the electric push rod 17, the distance between the substrate body 3 on the loading platform 2 and the drill bit 7 is controlled to achieve the control of the punching depth, which is convenient for improving the stability during punching; after the drill bit 7 is aligned with the punching position on the substrate body 3, as the electric push rod 17 pushes the substrate body 3 continuously closer to the drill bit 7, at this time the substrate body 3 is gradually covered by the dust collection hood 19, and a large amount of dust generated during the punching of the drill bit 7 is sucked into the cloth bag 20 by the piston 12, reducing or avoiding the harm to the operator's body caused by the generated dust. The remaining small amount of dust falls into the receiving groove 18 and is uniformly cleaned with a brush or a spray gun after punching.
