[0040] Reference Figure 2The track 10 may include a slotted plate 11 and a cover plate 12 covering the slot, the cover plate 12 extends into the slot in the X direction, i.e., the width direction of the material strip 100, so that the two side walls of the slot, the bottom wall of the slot and the bottom surface of the cover plate 12 form a slot 13; the distance between the two side walls of the slot is the width of the slot 13, and the distance between the bottom surface of the cover plate 12 and the bottom wall of the slot is the thickness of the slot 13; the width of the slot 13 is slightly larger than the width of the material strip 100, and the thickness of the slot 13 is slightly larger than the thickness of the material strip 100, so as to position the material strip 100 and to have a certain interval between the material strip 100 and the slot 13, so as to ensure that the material strip 100 can move; in some embodiments, the width of the slot 13 = the width of the material strip 100 + 0.05 to 0.1 mm, and the thickness of the slot 13 = the thickness of the material strip 100 + 0.05 to 0.1 mm.

In some optional embodiments, In the embodiment, the second avoidance groove penetrates the cover plate 12 along the Z direction, so that the ratchet 21 can extend into the material slot 13, so that the ratchet 211 is inserted into the positioning hole of the material belt 100; as the first motor 22 continues to rotate, the ratchet 211 drives the material belt 100 to move along the Y direction, i.e., the length direction of the material belt 100, until the ratchet 211 leaves the positioning hole of the material belt 100, and at the same time, the next ratchet 211 is inserted into the next positioning hole of the material belt 100, so that the material belt 100 moves intermittently at equal intervals along the Y direction. When replacing the material belt 100, the piston rod of the second telescopic cylinder 23 is extended, the ratchet 21 leaves the material slot 13, and then the new material belt 100 is inserted into the material slot 13, and then the piston rod of the second telescopic cylinder 23 is retracted, and the ratchet 211 is inserted into the positioning hole of the new material belt 100 again, and the new material belt 100 is operated.

[0043] Reference Figure 1 One or more second material pulling units 120 may be arranged between the feeding unit 20 and the first material pulling unit 80 , so that the material belt 100 does not need to pass through all the workstations before working, thereby reducing the waste of the material belt 100 .

[0044] In this embodiment, the spacing between two adjacent first terminals 101 on the material strip 100 is d, and the feeding unit 20, the first pulling unit 80 and the second pulling unit 120 drive the material strip 100 to move intermittently at an equal distance of 2d, that is, N=2, and the material strip 100 moves a distance of 2d along the Y direction. After the central body 102 cutting unit 30, the visual inspection unit 40, the defective product cutting unit 50, the second terminal 110 assembly unit 60, and the positioning clamping unit 70 are activated once, the material strip 100 moves a distance of 2d along the Y direction again, and the central body 102 cutting unit 30, the visual inspection unit 40, the defective product cutting unit 50, the second terminal 110 assembly unit 60, and the positioning clamping unit 70 are activated once again, and this reciprocating cycle is repeated until all the first terminals 101 on the material strip 100 are assembled, that is, each time the material strip 100 moves once, the assembly of two first terminals 101 can be completed, thereby improving production efficiency.

[0045] Reference Figure 4 , the visual inspection unit 40 may include a camera 41 and a lens 42 mounted on the camera 41, the lens 42 is facing the material belt 100 in the material slot 13, and in order to facilitate the camera 41 to capture a clearer image, a backlight 43 is installed on the side of the track 10 away from the lens 42, and in order to facilitate the detection of multiple first terminals 101, the camera 41 is connected to a fourth mechanical arm 44 that drives it to reciprocate along the Y direction. In this embodiment, the camera 41 is a CCD camera 41. After the camera 41 captures the image of the first terminal 101, the size and other parameters of the first terminal 101 are calculated according to the algorithm preset in the camera 41, and compared with the set threshold value, so as to determine whether the first terminal 101 is qualified; and the signal of the unqualified first terminal 101 is transmitted to the defective product cutting unit 50. Obviously, the signal of the camera 41 can be received by a programmable processor (PLC) in the prior art, and the defective product cutting unit 50 can be controlled to operate according to the signal. It is understandable that the plate body 11 of the track 10 corresponding to the lens 42 is provided with a hole (not shown) penetrating along the Z direction, so that the backlight 43 can illuminate the material belt 100 .

[0046] Reference Figure 5The defective product cutting unit 50 may include an upper mold 31 plate, a stripping plate 52, a lower mold 32 plate, and a pressure device 54 that drives the upper mold 31 plate to slide back and forth along the Z direction, which are arranged in sequence along the Z direction, i.e., the thickness direction of the material strip 100; the pressure device 54 may be an air cylinder, an oil cylinder, etc.; the track 10 is located between the stripping plate 52 and the lower mold 32 plate; a stripping spring 55 is provided between the upper mold 31 plate and the stripping plate 52, and the upper mold 31 plate and the stripping plate 52 are connected by equal height screws 56; the lower mold 32 plate is provided with N first lower knives 57; the upper mold 31 plate is provided with N first upper knives 58 that match the N first lower knives 57 one by one; each first upper knife 58 is connected to a driving mechanism 59 that drives it to slide back and forth along the thickness direction of the material strip 100, so that each first upper knife 58 can complete cutting separately; the stripping plate 52 has a first through cavity that slides with the N first upper knives 58 respectively. In this embodiment, N=2. The pressure device 54 drives the upper mold 31 to move toward the material strip 100 along the Z direction, driving the stripping plate 52, the first upper knife 58 and the driving mechanism 59 to move toward the material strip 100 at the same time. After the stripping plate 52 presses the material strip 100, the upper mold 31 continues to move, and the pressing spring 314 is compressed, thereby pressing the material strip 100. Then the driving mechanism 59 drives the first upper knife 58 corresponding to the defective first terminal 101 to move toward the material strip 100 until the defective first terminal 101 is cut off. By setting the driving mechanism 59 to drive a single first upper knife 58, when the material strip 100 moves multiple first terminals 101 at a time along the Y direction, only the defective first terminal 101 is cut. It should be noted that although Figure 5 Only one stripping spring 55 and one equal-height screw 56 are shown, but in fact, four stripping springs 55 and four equal-height screws 56 are provided, and the four stripping springs 55 are distributed in a diamond shape, and the four equal-height screws 56 are distributed in a rectangular shape, to ensure that the upper mold 31 plate and the stripping plate 52 are evenly stressed and have sufficient clamping force to clamp the material strip 100.
