[0002] A jumper is a metal wire that connects two points on a circuit board. Figure 10 As shown in the figure, this is a "U"-shaped jumper finished product that our company currently needs to produce. The basic shape is a "U" shape bent from a sheathed conductive cable. During production, the insulation sheath of the cable needs to be stripped and a layer of metal tin material is attached to the exposed end.

[0037] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0038] For example, see the attached Figure 1 The utility model provides an automatic production equipment for jumper wires, which is used to produce the following Figure 10 The "U"-shaped jumper finished product 800 shown in the figure, the jumper automatic production equipment in this embodiment includes a cable stripping module 100, an end flux dipping module 200, an end soldering module 300, a cable correction module 600, a cable step-by-step drawing module 500, and a jumper punching and forming module 400, which are arranged in sequence from left to right. One end of the bundled sheathed conductive cable is inserted from one side of the cable stripping module 100. Driven by the cable step-by-step drawing module 500, the cable can pass through the cable stripping module 100, the end flux dipping module 200, the end soldering module 300, the cable correction module 600, the cable step-by-step drawing module 500, and the jumper punching and forming module 400 in sequence.

[0039] Among them, as attached Figure 7 As shown, the cable stripping module 100 includes a stripping seat 110, a stripping cavity is provided in the stripping seat 110, and stripping module cable limiting holes 120 are provided on the left and right sides of the stripping seat 110. The sheathed conductive cable can pass through the stripping cavity from the stripping module cable limiting holes 120 on the left and right sides of the stripping seat 110. The stripping seat 110 is symmetrically provided with a first stripping knife 130, a second stripping knife 140 and a stripping drive mechanism. The ends of the first stripping knife 130 and the second stripping knife 140 can approach each other or separate in reverse under the drive of the stripping drive mechanism. The first stripping knife 130 and the second stripping knife 140 are symmetrically arranged up and down. When the two knives approach each other to the closest point, a section of the insulating sheath on the sheathed conductive cable can be cut and stripped. At the same time, a negative pressure dust suction pipe 150 is connected to one side of the stripping cavity, which can suck the cut and stripped insulating sheath out of the stripping cavity using a principle similar to that of a vacuum cleaner; as shown in the attached figure Figure 8 As shown, the end flux dipping module 200 includes a flux storage tank 210, into which flux is injected, and flux module cable limiting holes 220 are provided on both sides of the flux storage tank 210. The sheathed conductive cable can pass through the flux storage tank 210 from the flux module cable limiting holes 220 on both sides of the flux storage tank 210 and be coated with flux; as shown in the attached Figure 9 As shown, the end soldering module 300 includes a tin material storage tank 310, and a tin material heating and heat preservation device 330 is provided at the bottom of the tin material storage tank 310.

The cable correction wheels of the horizontal correction unit 610 and the vertical correction unit 620 can press the sheathed conductive cable into a straight line from four directions, front and back, thereby ensuring the processing size of the finished product. Usually, the cable correction module 600 is arranged between the cable stepping pulling module 500 and the end soldering module 300, so as to minimize the additional influence of other modules on the sheathed conductive cable.

[0041] As attached Figure 3 As shown, the cable step-by-step drawing module 500 includes a drawing drive device 520 and a drawing wheel assembly 510.

The sheathed conductive cable is driven forward by the rotation of the cable drawing wheels.

[0042] As attached Figure 2 , Attachment Figure 4 ~Attachment Figure 6As shown, the jumper wire punching and forming module 400 includes a forming module back plate 410, a cable feeding through hole 411 is provided in the middle position of the forming module back plate 410, and a plurality of processing units 420 are provided around the cable feeding through hole 411 on the forming module back plate 410. The plurality of processing units 420 respectively drive the jumper wire bottom limit block 480, the first side correction block 460 and the second side correction block 470 installed with a cable bending wheel 430, a cable bending top rod 440, and a cable end cutting knife 450. The processing unit 420 includes an actuating block moving rail 421 fixedly provided on the forming module back plate 410 and an actuating block driving device 423. The actuating block moving rail 421 sliding rail is connected to a telescopic actuating block. The actuating block driving device 423 is connected to the telescopic actuating block driving device for driving the telescopic actuating block to move back and forth along the actuating block moving rail 421. The cable bending wheel 430, the cable bending top rod 440, the cable end cutting knife 450 The top rod 440, the cable end cutting knife 450, the jumper bottom limit block 480, the first side correction block 460 and the second side correction block 470 are respectively fixed on the telescopic actuating block of one of the processing working units 420, wherein the number of the cable end cutting knives 450 is two, and the two cable end cutting knives 450 are symmetrically arranged with the center of the cable feeding perforation 411 as the reference, and the jumper bottom limit block 480 is provided with a jumper bottom limit groove on the side facing the cable feeding perforation 411, and the first side correction block 460 and the second side correction block 470 are also symmetrically arranged with the center of the cable feeding perforation 411 as the reference, and the cable bending wheel 430, the cable bending top rod 440, the cable end cutting knife 450, the jumper bottom limit block 480, the first side correction block 460 and the second side correction block 470 can all approach or move away from the center of the cable feeding perforation 411 under the drive of the processing working unit 420.

[0043] The working process of this embodiment is as follows:

[0044] First, one end of the sheathed conductive cable is manually pulled through the stripping chamber, the flux storage tank 210, the tin material storage tank 310, the horizontal correction unit 610, and the vertical correction unit 620 in sequence, and finally the end of the sheathed conductive cable is placed between the pulling wheel group 510 of the cable stepping pulling module 500, and then the production equipment is started. Under the pull of the cable stepping pulling module 500, the sheathed conductive cable begins to move step by step. The sheathed conductive cable completes the end stripping process in the cable stripping module 100, the end flux dipping process in the end flux dipping module 200, the end tin material attachment process in the end soldering module 300, and the sheathed conductive cable straightening process in the cable correction module 600, and finally reaches the jumper punching and forming module 400. At the jumper punching and forming module 400, two processes are first completed with the cooperation of the cable bending wheel 430 and the cable bending top rod 440. The U-shaped jumper 800 is then bent 90 degrees at a time by the cable bending push rod 440 and the cable bending wheel 430. The two bending operations required for a U-shaped jumper product 800 are completed. The U-shaped jumper product 800 is supported from below by the jumper bottom limit block 480, and the first side correction block 460 and the second side correction block 470 are pressed toward the U-shaped jumper product 800 from both sides. The goal of this is to suppress the U-shaped jumper product 800 again to prevent the cable from being displaced during the bending process. Finally, the two symmetrically arranged cable end cutting knives 450 are used to cut it off in the middle of the peeled part of the foreskin conductive cable. The symmetrical cutting method on both sides can ensure that the force on both sides of the cutting position is even and no unilateral bending will occur. In this way, a complete U-shaped jumper product 800 is processed.
