Detailed Embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0022] The present utility model provides a technical solution: As Figure 1 and Figure 5As shown in the figure, in this embodiment, the punching mechanism for the low-granularity bare copper chip carrier tape includes a mounting plate 1. A mounting frame 2 is fixedly connected to the top of the mounting plate 1. A guiding component 3 is fixedly connected to the inner wall of the mounting frame 2. The guiding component 3 includes a sliding seat 301. A chute 302 is formed at the top of the sliding seat 301. A driving motor 303 is fixedly connected to the back of the mounting frame 2. The output end of the driving motor 303 is fixedly connected to a bidirectional lead screw 304. A protective spring 305 is movably sleeved on the surface of the bidirectional lead screw 304. A guiding plate 306 is threadedly connected to the surface of the bidirectional lead screw 304. A rotating shaft 307 is rotatably connected to the inner wall of the guiding plate 306. A conveying roller 308 is fixedly connected to the surface of the rotating shaft 307.

[0023] Before the drill bit 18 punches the carrier tape, place the carrier tape between the two guiding plates 306 and start the driving motor 303. The bidirectional lead screw 304 starts to rotate. The two guiding plates 306 approach each other on the surface of the bidirectional lead screw 304 through the sliders at their bottom ends and squeeze the protective spring 305. The elasticity of the protective spring 305 can prevent the guiding plate 306 from moving too far and squeezing the carrier tape to cause damage. After the guiding plate 306 moves a certain distance, the positions of the two guiding plates 306 fix the carrier tape to ensure the accuracy of the drilling position. At the same time, the conveying roller 308 rotates as the carrier tape moves and conveys the carrier tape to ensure the smoothness of the carrier tape movement.

[0024] A first connecting plate 4 is fixedly connected to the right side of the mounting frame 2. A mounting roller 5 is rotatably connected to the front of the first connecting plate 4. A first guiding roller 6 is rotatably connected to the front of the first connecting plate 4. A cleaning component 7 is fixedly connected to the inner wall of the mounting frame 2.

[0025] The number of the cleaning components 7 is set to two. The two cleaning components 7 include a dust suction plate 701. A dust suction pump 702 is fixedly connected to the side of the dust suction plate 701 away from the sliding seat 301. The dust suction pump 702 is fixedly connected to the front and back sides of the mounting frame 2. A collection box 703 is fixedly connected to the end of the dust suction pump 702 away from the dust suction plate 701.

[0026] A second connecting plate 8 is fixedly connected to the left side of the mounting frame 2. A second guiding roller 9 is rotatably connected to the front of the second connecting plate 8. A connecting frame 10 is fixedly connected to the back of the second connecting plate 8. A rotating motor 11 is fixedly connected to the back of the connecting frame 10. A driving gear 12 is fixedly sleeved on the output shaft of the rotating motor 11. A transmission gear 13 is meshed with the surface of the driving gear 12. A rotating rod 14 is fixedly connected to the inner wall of the transmission gear 13. A winding roller 15 is fixedly sleeved on the surface of the rotating rod 14.

[0027] A hydraulic rod 16 is fixedly connected to the top of the mounting frame 2. A connecting base 17 is fixedly connected to the bottom end of the hydraulic rod 16. A drill bit 18 is fixedly connected to the bottom end of the connecting base 17. A support plate 19 is fixedly connected to the left side of the connecting base 17.

[0028] The output end of the hydraulic rod 16 penetrates through the mounting frame 2 and extends into its interior. Two limiting rods are provided at the top end of the connecting base 17, and the two limiting rods are composed of two sliding rods.

[0029] A suction fan 20 is fixedly connected to the top end of the mounting frame 2. An air inlet pipe 21 is fixedly connected to the bottom end of the suction fan 20. A blowing pipe 22 is fixedly connected to the bottom end of the air inlet pipe 21. The blowing pipe 22 is movably installed in the middle of the support plate 19.

[0030] When the carrier tape moves to below the drill bit 18, the hydraulic rod 16 is started, so that the connecting base 17 and the drill bit 18 move downward, and the stability during the downward movement is ensured by the two limiting rods on the connecting base 17. After moving down a certain height, the drill bit 18 contacts the carrier tape and drills the carrier tape. At the same time, the suction fan 20 is started, external air enters the air inlet pipe 21 and is sprayed out through the blowing pipe 22, and the chips generated by drilling are blown out of the carrier tape cavity. At the same time, the dust suction pump 702 is made to work, and the blown chips are sucked into the collection box 703 through the dust suction plate 701, preventing the chips from falling on the sliding seat 301 and the mounting frame 2 and causing secondary pollution to the carrier tape.

[0031] The utility model provides a punching mechanism for a low-particle-naked copper chip carrier tape, and the specific working principle is as follows:

[0032] During use, the carrier tape is installed on the mounting roller 5, and sequentially passes through the first guide roller 6, the guide plate 306 and the second guide roller 9, and is installed on the winding roller 15. The driving motor 303 is started, the bidirectional lead screw 304 starts to rotate, and the two guide plates 306 approach each other on the surface of the bidirectional lead screw 304 through the sliders at their bottom ends and compress the protective spring 305. After moving a certain distance, the two guide plates 306 fix the position of the carrier tape to ensure the accuracy of the drilling position. At the same time, the conveying roller 308 rotates as the carrier tape moves to convey the carrier tape. After the carrier tape is limited, the hydraulic rod 16 is started, so that the connecting base 17 and the drill bit 18 move downward. After moving down a certain height, the drill bit 18 contacts the carrier tape and drills the carrier tape. At the same time, the suction fan 20 is started, external air enters the air inlet pipe 21 and is sprayed out through the blowing pipe 22, and the chips generated by drilling are blown out of the carrier tape cavity. The dust suction pump 702 is made to work, and the blown chips are sucked into the collection box 703 through the dust suction plate 701. At the same time, the rotating motor 11 is started, and its output shaft drives the driving gear 12 to rotate, and the transmission gear 13 drives the winding roller 15 to rotate, so as to wind the carrier tape while it moves.

[0033] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
