This allows for the simultaneous gripping of two U-shaped PIN wires.

[0058] Preferably, see Figure 7 As shown, a through-beam sensor 80 is installed above the slide 31 to detect and identify the presence of material.

[0059] Furthermore, the slide 31 of the feeding assembly 30 is formed by a slide plate group 50, each slide plate group 50 including two parallel and vertically arranged slide plates 51; the slide plate 51 is provided with the above-mentioned slide 31; the slide 31 is inclined, after the wire taking mechanism 20 places the U-shaped PIN wire on the slide plate group 50, the U-shaped PIN wire rides on the two slide plates 51 (that is, the two copper feet of the U-shaped PIN wire rest on the outside of the two slide plates 51, and the middle connecting part between the two copper feet rests on the slide 31), and slides into the next station along the slide 31.

[0060] In this embodiment, the number of the first wire-taking assembly 21 and the second wire-taking assembly 22 is the same as that of the slide plate assembly 50. It includes two slide plate assemblies 50 arranged side-by-side at intervals, used to simultaneously receive two U-shaped PIN wires.

[0064] By forcing the adjusting plate 63 to slide along the slide rail, the two follower 64 synchronously drive the two slide plates 51 in the same slide plate group 50 to move towards or away from each other, thereby adjusting the distance between the two slide plates 51 in the slide plate group 50.

[0065] It also includes a linear module for driving the adjustment plate 63 to slide along the slide rail direction.

[0066] Furthermore, the adjustment assembly 60 also includes a second slide rail 65 disposed on the base along the slide rail direction; the second slide rail 65 includes a second fixed rail 65a fixedly disposed on the base along the slide rail direction, and a second moving rail 65b adapted to the second fixed rail 65a; the adjustment plate 63 is relatively fixedly disposed on the second moving rail 65b.

[0068] Furthermore, the adjustment assembly 60 also includes a first slide rail 61 arranged on the base along a direction perpendicular to the slide rail. The first slide rail 61 includes a first fixed rail 61b fixedly arranged on the base, and a plurality of first moving rails 61a adapted to the first fixed rail 61b. The two slide rails 51 in the slide plate assembly 50 are respectively fixedly arranged on the two first moving rails 61a.

The adjustment plate 63 drives the sliding plate 62 and the slide plate 51 to move along the first slide rail 61 through its own strip groove 63a and follower 64.

[0073] The number of guide groove groups is the same as that of the slide plate group 50; optionally, each adjusting plate 63 is provided with a set of guide groove groups for individually adjusting the spacing of the slide rails 51 within a slide plate group 50; more preferably, as Figure 6 As shown, the adjustment plate 63 is provided with two (or several) sets of guide grooves, which can simultaneously adjust the spacing between the slide plates 51 in the two slide plate groups 50.

The wire-taking mechanism 20 can simultaneously grab one or more U-shaped pin wires. The multi-joint robotic arm moves again, transferring the wire-taking mechanism 20 and the U-shaped pin wires to the slide rail 31 of the unloading component 30. The wire-taking mechanism 20 releases the U-shaped pin wires, and the pin wires slide from the slide plate 51 to the next station to continue the next step of production processing.

[0078] The present invention provides a PIN wire gripping and unloading mechanism with a more compact and flexible structure, which can be applied to the gripping and unloading of PIN wires of various specifications. It has a high degree of automation and greatly improves production efficiency.
