[0046] The working principle of the multi-wire cable terminal crimping and tin dipping device provided by the embodiment of the present application is as follows:

[0047] The lead release mechanism releases the material roll to the slitting mechanism 1, and the slitting mechanism 1 cuts the plurality of parallel leads at a set distance to form a plurality of leads with a set length, that is, the slitting mechanism 1 cuts the plurality of parallel leads at a set distance to form a plurality of leads with a set length, so that the head and tail of the final produced cable are separated. Specifically, when the slitting mechanism 1 is working, the first cylinder 11 drives the lead separation module to move to a set position and stop, and then the second cylinder 14 drives the lead separation knife 13 to move to a set position and contact the lead. The first cylinder 11 drives the lead separation module to retreat, thereby cutting a slit between the leads. The first guide rail and the second guide rail respectively play a guiding role.

[0048] After the lead separation is completed, the traction mechanism 5 pulls the wire rod (a plurality of parallel leads released from the material roll) to the cutting mechanism 2, and the cutting knife of the cutting mechanism 2 cuts one end of the wire rod, and then the terminal crimping mechanism 3 drives the cut wire rod to rotate 90 degrees to crimp the terminal. Specifically, the lead moving and rotating group 32 clamps and rotates the wire rod by 90° so that the end of the wire rod is located below the terminal crimping die 33, the terminal feeding group 31 simultaneously pushes the terminal to the lower side of the terminal crimping die 33, the two push knives 341 clamp a single lead wire therebetween, and the driving part drives the two push knives 341 to move a certain distance away from the terminal crimping die 33 along the slit between the leads, thereby separating the lead adjacent to the single lead and not blocking the terminal crimping of the end. At the same time, the terminal crimping die 33 descends to crimp the terminal on one end of the lead. The plurality of leads are horizontally moved from right to left under the action of the lead moving and rotating group 32, thereby crimping the terminals from right to left in sequence. After crimping each terminal, the lead moves one distance to the right;

[0049] After the plurality of parallel leads are crimped, the lead moving and rotating group 32 clamps the wire rod and reversely rotates it by 90°, and then the traction mechanism 5 advances to clamp the end of the wire rod and pulls it a distance, so that the wire rod sequentially passes through the cutting mechanism 2 and the tin dipping mechanism 4. The clamping and rotating mechanism 42 of the tin dipping mechanism 4 clamps the wire rod and makes a certain node of the wire rod reach the cutting mechanism 2 (the tin dipping mechanism 4 is located on the right side of the cutting mechanism 2). Once the clamping and rotating mechanism 42 of the tin dipping mechanism 4 clamps the wire rod, the traction mechanism 5 retreats, and then the cutting mechanism 2 cuts the wire rod again according to the set length, thereby forming a plurality of lead cable semi-finished products with a set length.

[0050] The clamping and rotating mechanism 42 drives the plurality of lead cable semi-finished products to rotate about 90° and makes the non-crimped terminal end of the lead downward to dip in the tin, thereby forming a plurality of lead cables. Then the plurality of lead cable products reversely rotate about 90°, thereby making the plurality of lead cable products return to the horizontal position. Finally, the lead receiving mechanism clamps the product and drops it into the collection mechanism.

[0051] Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein can be applied to other embodiments without departing from the spirit or scope of the application. Thus, the present application is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
