Abstract
Description
Technical Field
[0001] The invention relates to the technical field of fisheye terminal processing equipment, in particular to a one-step forming connector fisheye terminal processing technology. Background Art
[0002] Fisheye terminals are electronic devices that achieve circuit connections through crimping, named for their resilient structure, which resembles a fisheye. They are widely used in automotive electronics, energy equipment, security monitoring, and smart home applications, and are particularly suitable for applications requiring high current and high reliability. They consist of a base, two arc-shaped springs, and a prong. The springs face each other to form a fisheye hole. When pressed into a PCB hole, the springs compress and contract, deforming elastically. This creates a tight connection with low contact resistance, eliminating the need for soldering for electromechanical interconnection. Fisheye terminals are punched into the substrate using a punch to create the fisheye hole.
[0003] During the stamping process, due to the thin thickness of the substrate, the punch knife squeezes the substrate to cause it to deform during the stamping process, accompanied by the generation of metal elasticity. At this time, the substrate bounces up when the upper die and the lower die are separated, causing the substrate to tilt between the upper die and the lower die, thereby affecting the stamping effect of the fisheye terminal and causing waste of material. At the same time, the clamping device of the existing stamping equipment is not convenient to adjust according to the width of the substrate, affecting the clamping effect of the substrate.

Beneficial effects
[0016] The present invention provides a one-step molding process for connector fisheye terminals. Compared with the prior art, it has the following advantages: The one-time forming connector fisheye terminal processing technology uses two sets of oppositely arranged threads set at the outer end of the bidirectional lead screw to enable the two sets of clamping plates to move towards each other at the top end of the guide rail, which is convenient for free adjustment according to the width of the substrate. At the same time, during the process of clamping the substrate, the clamping plates can prevent the substrate from bouncing up due to the elastic force generated by the deformation after stamping.

The two sets of feed rollers are set to the same speed to ensure smooth substrate feeding. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example
[0021] See also Figure 1-5 The one-time forming connector fisheye terminal processing technology includes a stamping box 1, a stamping mechanism 2 is provided inside the stamping box 1, the stamping mechanism 2 includes a lower punch 201 fixedly connected to the bottom end of the inner cavity of the stamping box 1, and a clamping mechanism 3 is provided at the top of the lower punch 201. The clamping mechanism 3 includes a top plate 301 fixedly connected to the top of the lower punch 201, and the top of the top plate 301 is symmetrically fixedly connected with a guide rail 302, and the top of the guide rail 302 is symmetrically slidably connected with a splint 303. The internal rotation of the splint 303 is connected to a guide wheel 304, and a bidirectional screw rod 305 is symmetrically threaded between the two splints 303. The purpose of this arrangement is that during the stamping process of the substrate, the two sets of clamps 303 clamp the substrate from both sides, preventing the substrate from being squeezed and deformed to generate elastic force during the stamping process, so that the substrate bounces up from the top of the lower punch 201, thereby avoiding the tilt of the bounced substrate, affecting the accuracy and effect of the fisheye terminal stamping, and preventing material waste. The guide wheel 304 inside the clamp 303 facilitates the movement of the substrate between the two sets of clamps 303.
[0022] The stamping mechanism 2 also includes a connecting rod 202 symmetrically fixedly connected to the top of the lower punch 201, the outer end of the connecting rod 202 is slidably connected to the upper punch 203, the punching box 1 is fixedly connected to a punching cylinder 204, the output end of the punching cylinder 204 is fixedly connected to a punching column 205, the punching column 205 is slidably connected to the punching box 1, and the punching column 205 is fixedly connected to the upper punch 203. The purpose of this arrangement is that during the stamping process, the punching cylinder 204 drives the punching column 205 to move up and down inside the punching box 1, thereby closing the upper punch 203 and the lower punch 201, thereby completing the stamping operation.
[0023] The clamping mechanism 3 also includes a shell 306 fixedly connected to one side of the two guide rails 302, and the interior of the shell 306 is symmetrically connected to a support rod 307 for rotation. One end of the support rod 307 is fixedly connected to a transmission bevel gear 308, and the outer end of the transmission bevel gear 308 is meshed with a connecting bevel gear 309. The transmission bevel gear 308 and the connecting bevel gear 309 are rotationally connected to the interior of the shell 306, and the connecting bevel gear 309 is fixedly connected to the bidirectional screw rod 305.

The outer end of the conduction bevel gear 3011 is fixedly connected to a rotating column 3012, and the rotating column 3012 is rotationally connected to the shell 306. The purpose of this setting is that when adjusting the spacing between the two sets of splints 303, a hexagonal bolt is used to drive the rotating column 3012 to rotate at the outer end of the outer shell 306. At this time, the rotating column 3012 drives the transmission bevel gear 3011 to rotate inside the outer shell 306. At the same time, the transmission bevel gear 3011 drives the two connecting bevel gears 3010 at its outer end to drive the transmission bevel gear 308 connected to the support rod 307 to rotate.

Example
[0024] See also Figure 1-10 This embodiment, based on the first embodiment, provides a one-step process for processing connector fisheye terminals: Feed holes are symmetrically formed on both sides of the punch box 1, and a groove is formed at the outer end of the punch box 1. A box door 4 is rotatably connected to the inner portion of the groove, and a processing table 5 is fixedly connected to the bottom end of the punch box 1. The purpose of this arrangement is to facilitate opening the punch box 1, thereby adjusting the distance between the two clamping plates 303 by rotating the rotating column 3012. At the same time, the box door 4 has the effect of sound insulation and noise reduction.
[0025] A waste hole is provided at the bottom of the lower punch 201, and a ramp 6 is provided inside the processing table 5. The waste hole is connected to the ramp 6, and a conveyor belt 7 is rotatably connected inside the ramp 6. The purpose of this arrangement is that the waste generated during the stamping process of the substrate enters the ramp 6 from the waste hole at the bottom of the lower punch 201, and the conveyor belt 7 inside the ramp 6 transports the waste to the outer end of the processing table 5.
[0026] The top of the processing table 5 is symmetrically fixedly connected with a first connecting plate 8, an upper pressure roller 9 is rotatably connected between the two first connecting plates 8, a slide groove 10 is provided at the outer end of the first connecting plate 8, a slider 11 is slidably connected inside the slide groove 10, a lower pressure roller 12 is rotatably connected between the two sliders 11, a spring is fixedly connected between the slide groove 10 and the slider 11, and the first connecting plate 8 is arranged at the feed port of the stamping box 1. The purpose of this arrangement is that the substrate is arranged in a roll shape, and during the feeding process, the substrate bends with an arc, and the bent substrate affects the accuracy and effect of its stamping. During the feeding process, the elastic force generated by the spring causes the lower pressure roller 12 and the upper pressure roller 9 to squeeze the substrate, thereby flattening the substrate.
[0027] The top of the processing table 5 is symmetrically fixedly connected to a second connecting plate 13, and a feed roller 14 is rotatably connected between the two second connecting plates 13. The outer end of one of the second connecting plates 13 is fixedly connected to a connecting shell 15, and the outer end of the connecting shell 15 is fixedly connected to a servo motor 16. The interior of the connecting shell 15 is rotatably connected to a transmission flat gear 17 and a driven flat gear 18. The transmission flat gear 17 is meshed with the driven flat gear 18, and the driven flat gear 18 is fixedly connected to one of the feed rollers 14. The purpose of this setting is that during the feeding process, the servo motor 16 drives the pulley 19 fixed at its output end to rotate inside the connecting shell 15, and at the same time the connecting belt 20 drives another pulley 19 to rotate. During the rotation of the pulley 19 fixed at the output end of the servo motor 16, the transmission flat gear 17 at its outer end drives the driven flat gear 18 to rotate, so that the two sets of feeding rollers 14 rotate in opposite directions between the second connecting plate 13, thereby achieving the effect of feeding. Since the radius of the transmission flat gear 17 and the driven flat gear 18 are the same, the rotation speed of the two sets of feeding rollers 14 remains consistent, thereby improving the stability of the substrate transmission process.
[0028] The outer end of the other feeding roller 14 and the outer end of the transmission flat gear 17 are fixedly connected with a pulley 19. The pulley 19 at the outer end of the transmission flat gear 17 is fixedly connected to the output end of the servo motor 16. A connecting belt 20 is sleeved between the two pulleys 19.
