Description

Technical Field

[0001] The invention belongs to the field of automated production of twisted wire pins, and in particular relates to a dual-path production device for twisted wire pins. Background Art

[0002] The twisted wire elastic pin (commonly known as the twisted pin) is made of two layers of multi-strand copper wire twisted in reverse, welded at both ends into a bundle, one end pressed into the sleeve, and the other end upset. It has the characteristics of light weight, small size, and reliable contact, and is widely used in electronic components. Generally, the twisted beryllium copper stranded wire (common specifications are 0.40mm diameter) is automatically finely straightened, cut to a fixed length, and the two ends are automatically laser welded. The traditional process is to manually complete the cutting process and welding process on two devices, respectively, with low output and yield. Therefore, our company has designed a variety of automated equipment to improve production efficiency, such as: an automatic cutting and welding machine for twisted wire pins (application number 201822217138.3), an automatic cutting and welding device for twisted wire pins (201910073877.6), an automatic production machine for twisted wire pins (201811610829.8), and a fully automatic cutting machine for twisted wire pins (201920095301.5). In the above patents, whether a cutter or a laser is used to cut the twisted wire, a single twisted wire is cut one by one; the front-end wire feeding motor needs to wait until the twisted wire is cut and clamped away before the next wire feeding action can be performed, and the waiting time is long, and the utilization rate of the wire feeding motor is not high; and the rear-end welding mechanism also needs to wait for the next one after welding a twisted wire pin. It can be seen that the key point affecting the automated production efficiency of twisted wire pins is the cutting link, so it is necessary to study how to improve the cutting rate of the twisted wire.

[0050] Twisted wire pin dual-circuit cutting device

[0051] like Figure 6-13 The twisted wire pin dual-path cutting device 200 includes a cutter body 231 and a cutting drive mechanism 210 .

[0053] like Fig. 9 As shown, a movable cutter 233 is slidably arranged in the slide groove (a second stopper 235 and a first stopper 234 are respectively arranged on the front and both sides of the cutter body 231 to limit the movable cutter 233 in the slide groove), and a fixed cutter 232 is bolted in the notch, and the movable cutter 233 and the fixed cutter 232 are slidably sheared in cooperation.

[0055] like Fig.10 As shown, two fourth stranded wire through holes 241 are provided on the cutter body 231 above the movable cutter 233, and the two fourth stranded wire through holes 241 are respectively located directly above the two second stranded wire through holes 239; an air nozzle 236 is also provided at the air inlet of the fourth stranded wire through hole 241 on the cutter body 231, and when the second stranded wire through hole 239, the third stranded wire through hole 240 and the fourth stranded wire through hole 241 are connected at the same time, the air nozzle 236 is used to blow air into the inside, and the processed and cut stranded wire pins are blown out from the third stranded wire through hole 240 and the second stranded wire through hole 239 to prevent blockage.

[0056] like Figure 7 , 13 As shown, the cutting drive mechanism 210 includes a slide rail 212, a slider 213 and a cutting cylinder 211. The slider 213 is mounted on the slide rail 212 and connected to the cutting cylinder 211. The slider 213 is also connected to a movable cutter 233. A horizontal through-hole 237 is provided in the middle of the movable cutter 233. One end of the slider 213 is connected to the connecting hole 237 by a socket connection, so as to facilitate the removal and replacement of the movable cutter 233.

The fixed cutter 232 may be provided with two first stranded wire through holes 238, one for current use and one for standby, and the two first stranded wire through holes 238 are arranged perpendicular to the sliding direction of the movable cutter 233. The movable cutter 233 is provided with four third stranded wire through holes 240, which are arranged in a rectangular shape and are symmetrical in front, back, left and right directions.

[0059] When a first stranded wire through hole 238 currently in use is excessively worn, the fixed cutter 232 is removed, rotated 180 degrees and then installed and fixed, and the spare first stranded wire through hole 238 is simply replaced and continued to be used.

[0060] Similarly, when the currently used pair of third stranded wire through-holes 240 are excessively worn, the movable cutter 233 is removed, rotated 180 degrees and then installed back, and the spare pair of third stranded wire through-holes 240 is simply replaced and continued to be used.

[0063] The use process of the twisted wire pin double-way cutting device:

[0064] (1) The servo motor feeds the wire according to the set length, and the cutting cylinder 211 drives the cutter to reciprocate left and right to cut quickly. The cutter feeds the material in two ways. When one way is sent to the welding position for welding, the other way is returned to the material taking position, thereby improving the production efficiency.

[0065] (2) The stranded wire passes through the threading tube and enters the first stranded wire hole 238 and the third stranded wire hole 240 on the left. The movable cutter 233 is driven by the cutting cylinder 211 to move left to cut the stranded wire. At the same time, the product (stranded wire pin) is brought to the second stranded wire hole 239 on the left and falls onto the support plate 221, and then is transported away by the clamp; at this time, the first stranded wire hole 238 and the third stranded wire hole 240 on the right are aligned, and the stranded wire is driven by the servo motor to enter the third stranded wire hole 240 on the right. The cutting cylinder 211 is driven in the reverse direction, and the action is repeated to achieve continuous and rapid shearing.

[0066] Rotating jaw mechanism

[0073] The stranded wire pin feeding device 500 comprises a feeding hopper 520 , and a feeding chute 521 inclined to one side is provided on the feeding hopper 520 .

[0074] like Fig.14 , and also includes a material accumulation box 510 and a translation cylinder 540, which are located on the unloading side (inclined low side) of the unloading chute 521 and are used to collect the stranded wire pins; the unloading hopper 520 is installed on the translation cylinder 540 and is used to drive the unloading hopper 520 to move toward the material accumulation box 510.

[0075] like Fig.16 , 17 A lifting mechanism 530 is provided in the middle of the lower hopper 520 for lifting the stranded wire pin on the clamp. The lifting mechanism 530 includes a piston cylinder 531 and a piston rod 532. The piston rod 532 is located in the piston cylinder 531. The top of the piston rod 532 extends out of the piston cylinder 531. A top head 533 is provided on the top of the piston rod 532. A connector 534 is provided at the bottom of the piston cylinder 531 for connecting to a medium pressure source, such as an air pump, a hydraulic station, etc.

[0076] The top head 533 is in the shape of a truncated cone, and the flat top head is used to lift the twisted wire pin, and the conical surface facilitates the sliding of the twisted wire pin.

[0077] The lower surface of the top head 533 is provided with a second nut 535, and the piston rod 532 is connected to the second nut 535 by threaded fit. A circular hole is opened in the center of the lower hopper 520, and a first nut 522 is provided at the circular hole on the lower surface of the lower hopper 520, and the piston cylinder 531 passes through the circular hole and is connected to the first nut 522 by threaded fit. Bolt connection is adopted for easy disassembly and installation.

[0078] The use process of the feeding device:

[0079] (1) When the two ends of the stranded wire pin held by the clamp are welded, the clamp will open. Under normal circumstances, the stranded wire pin will naturally fall into the material storage box 510; when the stranded wire pin is adhered to the clamp (or normalized, it is involved every time), the stranded wire pin will not fall; at this time, the translation cylinder 540 drives the lower hopper 520 until the head 533 is located directly below the clamp (stranded wire pin).

[0080] (2) The top head 533 rises to lift the stranded wire pin from the clamping jaws, and the stranded wire pin slides along the conical surface of the top head 533 and the slope of the material discharge chute 521 into the material accumulation box 510.

[0081] Working process of the double-circuit production equipment for twisted wire pins:

[0082] (1) The stranded wire passes through the wire pressing hook 107, the direction-changing wheel 106, the upper threading tube 108, between the main wire feeding wheel 102 and the slave wire feeding wheel 103, and the lower threading tube 109 in sequence; the main wire feeding wheel 102 and the slave wire feeding wheel 103 clamp the stranded wire, and the wire feeding motor 104 feeds the wire according to the set length.

[0083] (2) The stranded wire is then passed through the first stranded wire through hole 238 and cut into stranded wire pins of fixed length by the stranded wire pin double-path cutting device.

[0084] (3) Two-way rotating clamp mechanism 300, one way sends the stranded wire pin to the welding position for welding, and the other way returns to the material taking position to clamp the stranded wire pin, and the two ways reciprocate alternately.

[0085] (4) The rotating clamp mechanism 300 sends the stranded wire pin to the welding position, the welding mechanism 400 welds one end of the stranded wire pin, the rotating clamp mechanism 300 rotates the stranded wire pin 180 degrees, and then welds the other end. During welding, there is nitrogen protection all around, which can improve the welding effect and also achieve the purpose of dust prevention.

[0086] (5) The stranded wire pin unloading device 500 delivers the stranded wire pins welded on the clamping jaws 303 into the storage box 510.

[0087] (6) The twisted wire pin detection sensor 600 may be a photoelectric sensor, facing the clamping jaw 303, and used to detect whether there is a twisted wire pin on the clamping jaw 303. If there is no product, the laser head will not weld, which can protect the service life of the clamping jaw 303.

[0088] The above description is only an application embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the protection scope of the present invention.
