[0033] like Figures 1 to 8 The center pin crimping device shown in the figure comprises a conveying mechanism 1, a cutting mechanism 2, a clamping and moving mechanism 4 and a crimping mechanism 3, wherein: Figure 1 As shown in the figure, the conveying mechanism 1 includes a transverse driving member 11 and a toggle member 12 connected to the transverse driving member 11, which is used to convey the center needle row according to a set direction; when the center needle row is moved, the center needle row is generally placed in a roll-up manner, and the conveying mechanism 1 is toggled to move the center needle spacing distance each time, thereby moving the center needle to the set direction. Figure 1 In the cutting mechanism 2 shown in;

[0034] The cutting mechanism 2 is arranged in front of the conveying mechanism 1 in the direction of conveying the center terminal, and is used to cut a single center pin from the center pin row; Figure 2 As shown in the figure, the center pin is arranged in a direction perpendicular to the length direction of the terminal block. When cutting, only the part connected to the terminal block needs to be cut off to cut off the center pin from the terminal block. It should be pointed out here that before cutting the terminal, the clamping moving mechanism 4 has moved to the position of the cutting mechanism 2 and clamped the center pin to be cut off.

[0035] Please refer to Figure 1 and Figure 2 In the embodiment of the utility model, the clamping and moving mechanism 4 is arranged opposite to the cutting mechanism 2 when in the initial position, and is arranged to reciprocate between the first position and the second position, for clamping and moving the terminal; in the embodiment of the utility model, the first position corresponds to the position of the cutting mechanism 2, and the second position corresponds to the position of the crimping seat 31; of course, it should be pointed out here that in order to simplify the control, in the embodiment of the utility model, the cutting mechanism 2 and the crimping mechanism 3 are in the same straight line position, so as to facilitate the movement of the clamping and moving mechanism 4;

[0036] The crimping mechanism 3 includes a crimping seat 31 and a crimping head 32, and is used for crimping the center needle. The crimping mechanism 3 is a prior art. The crimping mechanism 3 in the embodiment of the utility model is only used for crimping the center needle and the bare wire, because the center needle has been cut off from the needle row at the cutting mechanism 2 and moved to the position of the crimping seat 31 by the clamping and moving mechanism 4.

[0037] When the above-mentioned center pin crimping device is implemented, the conveying mechanism 1 first moves the terminal row forward the distance of a center pin, then the clamping moving mechanism 4 moves to the position of the cutting mechanism 2, and clamps the center pin to be cut off, and then the cutting mechanism 2 cuts the clamped center pin from the pin row, and then the clamping moving mechanism 4 clamps the center pin and moves it toward the crimping mechanism 3 until the center pin is placed on the crimping seat 31, and then the bare wire is inserted into the crimping position of the center pin, and finally the crimping head 32 is crimped toward the crimping position of the center pin to realize the crimping operation of fixing the bare wire on the center pin.

[0038] In the above embodiment, by dividing the crimping and cutting of the center needle into two processes, that is, by first cutting the center needle from the needle row on the cutting mechanism 2, and moving the cut center needle to the crimping mechanism 3 by the clamping and moving mechanism 4 to crimp the terminal, compared with the prior art, the displacement and shaking of the terminal caused by the cutting during crimping is avoided, and the reliability of crimping is improved.

[0039] Based on the above embodiments, Figure 3 As shown in , in the embodiment of the utility model, the toggle member 12 is pivotally connected to the transverse driving member 11 through a hinge spring, and the toggle member 12 is a wedge-shaped structure, and the side facing the direction of movement away from the center needle row is an inclined surface. That is, when the toggle member 12 moves toward the conveying direction of the terminal, the hinge spring on the toggle member 12 applies force to push the terminal row, and when it moves in the opposite direction, the hinge spring does not apply force, so that the upper inclined surface of the toggle member 12 contacts the needle row, and then the toggle member 12 rotates upward under the action of the inclined surface to bypass the lower center needle, and moves repeatedly in this way, so as to achieve the distance of moving one center needle each time; In addition, it should be pointed out here that in some embodiments of the utility model, the transverse driving member 11 has a variety of structural forms, such as a cylinder or a motor screw.

[0040] In the embodiment of the present utility model, in order to prevent the needle row from jumping when the needle row is pushed to move, please continue to refer to Figure 3 The device also includes a moving channel for the center needle row to move, and a pressing plate 5 is provided on the moving channel, and a long strip-shaped moving hole 51 is provided on the pressing plate 5 for the moving member 12 to penetrate. In this way, the movement of the center needle row in the height direction is limited by the setting of the moving channel and the pressing plate 5, and the pushing accuracy of the moving member 12 is also improved.

[0041] In the embodiment of the present utility model, the specific structural form of the cutting mechanism 2 is as follows: Figure 4As shown in the figure, the cutting mechanism 2 includes a cutting seat 21, a cutting piece 22 disposed adjacent to the cutting seat 21 and relatively movable in the vertical direction, and a cutting driving piece 23 for driving the cutting piece 22 to move relative to the cutting seat 21. The cutting piece 22 has a cutting opening 22a for the center needle row to penetrate. The cutting opening 22a is configured so that when the cutting driving piece 23 drives the cutting piece 22 to move, the cutting opening 22a and the cutting seat 21 perform a shearing action. Here, the cutting opening 22a is as shown in FIG. Figure 4 As shown in the figure, it is an opening through which the needle row can pass horizontally. By so setting, the center needle vertically connected to the needle row can be overlapped on the shear seat 21, so that when the shearing piece 22 moves downward, the connection between the center needle and the needle row can be sheared, thereby achieving the effect of shearing the center needle from the needle row; in some embodiments of the present utility model, in order to further improve the shearing effect, please continue to refer to Figure 4 The shearing seat 21 has an arc groove 21a adapted to the outer diameter of the center needle. By so arranging, the center needle is placed on the shearing seat 21 more closely, and the placement accuracy of the center needle is improved.

[0042] In some embodiments of the present invention, the specific structural form of the clamping moving mechanism 4 is as follows: Figure 5 and Figure 6 As shown in , the clamping and moving mechanism 4 includes a clamping member 41 and a second driving member 42 that drives the clamping member 41 to move back and forth. Of course, it should be pointed out here that the second driving member 42 also has a variety of structural forms, for example, it can be a cylinder or a motor screw structure, or a motor drives the gear to drive the rack to move back and forth in a straight line. In some embodiments of the utility model, the clamping member 41 is a clamping claw cylinder, and the clamping claw of the clamping claw cylinder has a clamping groove 41a adapted to the center needle. When clamping is performed specifically, the clamping claw is first opened, and then moved to the middle position where the center needle is in the two clamping claws, and the two clamping claws are brought close to each other until the center needle is fixed. By setting the above-mentioned clamping groove 41a, the clamping accuracy can also be improved.

[0043] In some embodiments of the present invention, in order to adapt to the crimping operation of center pins of different sizes, in the embodiments of the present invention, the height of the clamping member 41 can be adjusted. Figure 7 and Figure 8In some embodiments of the present utility model, the clamping and moving mechanism 4 further includes a connecting seat 43, one end of the connecting seat 43 is connected to the clamping member 41, and the other end is connected to the second driving member 42, the clamping member 41 is connected to the second driving member 42 through a vertical slide rail 44, and the connecting seat 43 has a first adjusting bolt 45 and a second adjusting bolt 46 arranged opposite to each other, and a positioning rod 47 is fixed on the second driving member 42 between the first adjusting bolt 45 and the second adjusting bolt 46. It should be pointed out here that in some embodiments of the present utility model, the axes of the first adjusting bolt 45 and the second adjusting bolt 46 are arranged on the same vertical line, and the positioning rod 47 is also located on the straight line. By such an arrangement, by adjusting the position of the first adjusting bolt 45 and the second adjusting bolt 46 toward one end of the positioning rod 47, the height of the connecting seat 43 can be adjusted, and then it can adapt to the clamping of center needles of different sizes, thereby improving the adaptability of the device.
