Description

Fully automatic wire single-end crimping tin dipping machine

technical field

The invention relates to the technology in the field of cable terminal assembly equipment, in particular to a fully automatic wire single-end crimping tin dipping machine.

Background technique

The cable is a kind of connecting cable, which is bonded together by multiple thin wires. At present, the cable has been widely used in the signal transmission or power connection of computers, household appliances, communication equipment, and digital equipment. There are terminals pressed at both ends for the connection between the cable and the cable connector, which not only facilitates the assembly of electronic equipment, but also ensures the reliability of signal transmission and connection between the internal circuit board of the electronic equipment or between electronic equipment. .

At present, in the process of terminal crimping, terminal feeding and terminal crimping are realized separately by two different drivers. Although two different drivers can also realize terminal feeding and crimping operations, this method makes the structure of the machine more complicated. , the operation and control are troublesome, it is difficult to ensure the continuity of the operation, and the energy consumption is high. Moreover, the cable needs to be divided before pressing the terminal. The traditional method is to use a branching frame to move vertically from top to bottom to separate the lines. However, since the branching frame only has one movement of moving up and down, it is impossible to straighten each branch line of the cable, so that when the terminal and the cable are riveted, errors are prone to occur, which affects the efficiency and quality of the riveting thread. In addition, before the soldering operation of the cable, the multiple metal wires at the solder end are not twisted together, so that when the cable is soldered to the circuit board and perforated, it is easy to be difficult to operate due to the dispersion of multiple metal wires, which affects product production efficiency and product quality. Therefore, the existing branching equipment should be improved to solve the above problems.

The working principle of the tin dipping machine is as follows: the terminals to be pressed are transported from the terminal delivery tray 21 to the bottom of the pressing end 221 of the pressing end device 22; Component 422 clamps the front end of the wire rod, and the horizontal wire moving sliding seat 412 drives the wire clamping assembly 422 to move laterally until the front end of the wire rod to be pressed reaches the bottom of the pressure end head 221; 357 have different shapes and designs, and the positions and angles of the first cam 348 and the second cam 357 installed on the rotating shaft 3321 are different. The motor 331 drives the transmission assembly 332 to make the rotating shaft 3321 rotate. The contact points of the second cam 357 and the second roller 356 are different. When the rotating shaft 3321 rotates, the second cam 357 first presses against the second roller 356, so that the hinged end of the second swing rod 355 and the second connecting rod 354 moves downward, driving the horizontal The drive rod 353 moves down, and the thread distribution frame 32 is inserted downward to the rightmost wire; at the same time, the first cam 348 rotates, the first connecting rod 345 rises, the figure-of-eight swing rod 342 rotates backward, and the lateral movement rod 344 moves backward, Pull the horizontal drive rod 353 to move backward, and the wire distribution frame 32 moves backwards to straighten the inserted wires backward; as the wires move to the left in sequence, the wire distribution frame 32 separates the wires one by one and straightens them. Circulation in turn; at the same time, the pressing end 221 moves downwards to rivet each of the separated and straightened wires with the terminals in turn; the wires after the riveted terminals are driven by the horizontal wire moving device 41 to move to the wire clamping mechanism 60 Directly ahead, the wire clamping assembly 422 of the wire moving mechanism 40 releases the wire, and the first clamping cylinder 621 moves forward longitudinally to clamp one end of the riveted terminal of the wire, and then moves backward to drive the wire to shuttle between the upper and lower seats in sequence. Between the knife assembly 53 and between the jaws 633 of the second clamping cylinder 631; the first clamping cylinder 621 moves back a certain distance and stops, and loosens the wire rod. At the same time, the clamping mouth 633 of the second clamping cylinder 631 The wire is clamped, and the wire clamp assembly 422 also clamps the wire; the tangential stripping and twisting mechanism 50 starts, the motor 521 drives the two-way ball screw 522 to rotate, the upper sliding seat 523 and the lower sliding seat 524 move opposite each other, the cutting on the upper and lower seats The knife assemblies 53 are in contact with each other. The first cutter 533 cuts off the wire as a whole, and the second cutter 534 on both sides cuts off the insulation at the ends of the two wires formed after cutting. When the second cutter 534 cuts the insulation, the second The second clamping cylinder 631 drives the wire to move a small distance backward, and the wire and metal wire are withdrawn from the insulation, and at the same time reserve space for the upper tooth plate 541 to press down, and the pressure drop metal wire of the upper tooth plate 541 is pressed tightly between the upper and lower tooth plates. Between; the vertical cylinder 5431 of the reciprocating drive assembly 543 drives the vertical rack 5432 to move, the first gear 5433 rotates and links the second gear 5436, the upper and lower horizontal racks move in opposite directions, and the upper and lower guides move accordingly. Drive the connecting rod to move laterally, forming an alignment between the upper and lower tooth plates Therefore, multiple metal wires are twisted together (during twisting, the clamping assembly 422 of the wire moving mechanism drives another segment of the cut wire to leave the second cutter 534 completely, and This section of wire and metal wire is withdrawn from the insulating skin, and the above-mentioned action of dividing the line and pressing the end is repeated); the tin-staining mechanism 70 starts, and the lateral displacement drive mechanism 72 drives the third clamping cylinder 75 to move closer to the second clamping cylinder 631, and the second clamping cylinder 631 moves closer. The three clamping cylinders 75 clamp the first half of the wire clamped by the second clamping cylinder 631, and at the same time, the second clamping cylinder 631 releases the wire, and the lateral displacement drive mechanism 72 drives the third clamping cylinder 75 to move to the flux in turn. Above the tank 13 and the tin tank 14, the overturning device 73 drives the third clamping cylinder 75 to turn down 90 degrees, so that the third clamping cylinder 75 is vertically downward, and the tin-staining drive assembly 74 drives the third clamping cylinder 75 to extend toward The flux tank 13 and the tin tank 14 are used to dip the end of the unpressed terminal of the wire rod into flux and tin. After the wire rod dipped in flux and tin, the third clamping cylinder 75 loosens it and drops it to the storage place, and circulates in turn .

The key point of the design of the present invention is that by integrating the terminal conveying and pressing mechanism, the branching mechanism, the wire moving mechanism, the tangential stripping and twisting mechanism, the pulling wire clamping mechanism and the tin dipping mechanism into one frame, each line of the wire is pressed Both ends can be separated and straightened, so that the riveting of the terminal and the wire is more accurate and stable, and the error rate is reduced. At the same time, the wire can be automatically cut, stripped, and twisted, which improves the efficiency of wire processing. In addition, the wire is dipped in flux and tin are also automated operations to achieve wire separation, crimping, cutting, peeling, twisting, and so on. Both fluxing and tinning are done automatically, which reduces the amount of manual labor, improves production efficiency and reduces production costs.

The above description is only a preferred embodiment of the present invention, and does not limit the technical scope of the present invention in any way, so any minor modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention are all valid. Still belong to the scope of the technical solution of the present invention.
