When the grid tube core placement seat 100 is positioned at the upper port 302, the grid tube core insertion sleeve 200 extends out of the upper port 302; A first torsion mechanism 400 and a second torsion mechanism 500 are respectively arranged on both sides of the grid tube core conveyor line 1, the first torsion mechanism 400 includes a first telescopic drive mechanism 401, a first torsion assembly and a first fixed clamp block 402 connected to the first telescopic drive mechanism 401, the second torsion mechanism 500 includes a second telescopic drive mechanism 501, a second torsion assembly and a second fixed clamp block 502 connected to the second telescopic drive mechanism 501, the first telescopic drive mechanism 401 and the second telescopic drive mechanism 501 can move towards or away from each other along the first horizontal straight line direction X, so as to drive the first fixed clamp block 402 and the second fixed clamp block 502 to approach each other and clamp the axial end of the grid tube core 14 on each grid tube core through-set 200 extending out of the upper port 302 when moving towards each other, the first torsion assembly includes a first space drive mechanism and a first torsion block 404 connected to the first space drive mechanism, the second torsion assembly includes a second space drive mechanism and a second torsion block 504 connected to the second space drive mechanism, so that the first torsion block 404 and Each of the second torsion blocks 504 can reciprocate along the first horizontal straight direction X, reciprocate along the second horizontal straight direction Y, and move up and down along the vertical direction Z.

The relative movement in the line direction Y rubs the other axial end of the grid tube core 14 on each grid tube core 14 to rotate around the axis of the grid tube core 14. After the twisting is completed, the first twisting mechanism 400 and the second twisting mechanism 500 move away from the twisted grid tube core 14, and then the lifting mechanism places the grid tube core placement seat 100 carrying the twisted grid tube core 14 back to the grid tube core conveying line 1, so that the twisted grid tube core 14 continues to be conveyed to the next workstation (for example, a workstation for performing the operation of connecting the outer sleeve and the grid tube core 14 to each other).

[0022] In the torsion system of the grid electrical connector provided by the present application, a plurality of grid tube core insertion sleeves 200 are arranged on the grid tube core placement seat 100 on the grid tube core conveyor line 1, and each grid tube core insertion sleeve 200 can be inserted with a grid tube core 14, and then the grid tube core placement seat 100 carrying the grid tube core 14 is lifted by a lifting mechanism to make the grid tube core insertion sleeve 200 extend out of the upper port 302, and each grid tube core 14 also extends out of the upper port 302 of the guide bin 300.

[0023] See also Figure 2 , Figure 3 and Figure 7According to a preferred embodiment of the present application, the first fixing clamp block 402 forms a plurality of first semicircular notches 403 arranged at intervals along the second horizontal straight line direction Y facing the second fixing clamp block 502, and the second fixing clamp block 502 forms a plurality of second semicircular notches 503 arranged at intervals along the second horizontal straight line direction Y facing the first fixing clamp block 402, and the number and position of the first semicircular notches 403 correspond to the notches. When the first fixing clamp block 402 and the second fixing clamp block 502 are close to each other, the arc-shaped wall surfaces of the first semicircular notch 403 and the corresponding second semicircular notch 503 clamp the outer circumference of the axial end of each grid tube core 14 on each grid tube core 14 extending out of the upper port 302, thereby more firmly clamping the outer circumference of the axial end of the grid tube core 14. In addition, the first torsion block 404 and the second torsion block 504 each have a surface in contact with the outer circumference of the other axial end of the grid tube core 14, which is a plane extending along the arrangement direction of the grid tube core 14, ensuring that they can contact all the grid tube cores 14 at the same time.

[0024] As other embodiments, instead of directly contacting and rubbing the grid tube core 14 through the first torsion block 404 and the second torsion block 504, the friction block 2 can be detachably installed on the first torsion block 404 and the second torsion block 504, and the grid tube core 14 can be rubbed by the friction block 2, so that the friction block 2 can be replaced in time.

[0025] See 1 to Figure 4 According to one embodiment of the present application, slots 101 are formed on both sides of the grid tube core placement seat 100 in the width direction, and a plurality of grid tube core insertion sets 200 are arranged along the length direction of the grid tube core placement seat 100. The grid tube core placement seat 100 can be placed along the conveying direction of the grid tube core conveying line 1. The lifting mechanism includes a displacement mechanism and a fork arm 3 connected to the displacement mechanism. The displacement mechanism can reciprocate along the first horizontal straight line direction X and lift and lower along the vertical direction Z to lift the grid tube core conveying line 1 on both sides. The fork arms 3 of each mechanism can extend into the slots 101 on both sides of the width direction of the grid tube core placement seat 100 to support the grid tube core placement seat 100 to rise from the lower port 301 of the guide bin 300 to enter the guide bin 300 and be positioned at the upper port 302. Both side walls of the guide bin 300 form an avoidance groove 303 extending upward from the lower end surface of the guide bin 300 along the vertical direction Z. The fork arms 3 can enter the avoidance groove 303 from the lower end surface of the guide bin 300 and move upward in the avoidance groove 303.

[0026] In addition, stopper strips 102 can also be formed on the two side surfaces in the width direction of the grid tube core placement seat 100. The grid tube core placement seat 100 rises from the lower port 301 of the guide bin 300 to enter the guide bin 300 and is positioned at the upper port 302. Specifically, the upper end surface of the stopper strip 102 can abut against the lower wall surface at the upper port 302 of the guide bin 300, and the side surface of the stopper strip 102 abuts against the inner wall of the guide bin 300. The inner wall of the guide bin 300 gradually expands outward from the upper port 302 toward the lower port 301, that is, the inner wall gradually narrows from the lower port 301 of the guide bin 300 toward the upper port 302. Ensure that the lower port 301 is smaller than the upper port 302, the grid tube core placement seat 100 can be easily guided from the lower port 301 into the guide bin 300, and then gradually tilts and narrows as the inner wall, and finally the side of the stop strip 102 abuts against the inner wall of the guide bin 300 to form an axial limit, the upper end of the stop strip 102 abuts against the lower wall surface at the upper port 302 of the guide bin 300 and is limited, and the lower end of the grid tube core placement seat 100 is supported and limited by the fork arm 3, and finally the grid tube core placement seat 100 is positioned at the upper port 302 of the guide bin 300, preparing for the subsequent operation of twisting the grid tube core 14.

[0027] See also Figures 1 to 5According to an embodiment of the present application, the first torsion block 404 is located above the first fixed clamping block 402, the second torsion block 504 is located above the second fixed clamping block 502, and the grid tube core wear kit 200 includes a fixed round seat 201 and a rotating round seat 202 rotatably connected to the upper part of the fixed round seat 201. Specifically, the fixed round seat 201 can form a rotating shaft 203 extending vertically upward, and the rotating round seat 202 is rotatably installed on the rotating shaft 203. The fixed round seat 201 The grid cylinder core 14 is arranged coaxially with the rotating circular seat 202, the axial lower end of the grid cylinder core 14 is sleeved on the outer peripheral side of the fixed circular seat 201, and the axial upper end of the grid cylinder core 14 is sleeved on the outer peripheral side of the rotating circular seat 202. When the twisting operation is performed, the axial lower end of the grid cylinder core 14 is clamped between the outer peripheral side of the fixed circular seat 201 and the first fixed clamping block 402 and the second fixed clamping block 502, that is, the outer peripheral side of the fixed circular seat 201 is pressed against the inner side of the axial lower end of the grid cylinder core 14, and the first fixed clamping block 402 and the second fixed clamping block 502 are pressed against the inner side of the axial lower end of the grid cylinder core 14. The second fixed clamping block 502 is pressed against the outer side of the axial lower end of the grid tube core 14; the axial upper end of the grid tube core 14 is clamped between the outer peripheral side of the rotating circular seat 202 and the first torsion block 404 and the second torsion block 504, that is, the outer peripheral side of the rotating circular seat 202 is pressed against the inner side of the axial upper end of the grid tube core 14, and the first torsion block 404 and the second torsion block 504 are pressed against the outer side of the axial upper end of the grid tube core 14. Since the first torsion block 404 and the second torsion block 504 are at the second horizontal The relative movement in the straight line direction Y rubs the axial upper end of the grid tube core 14 on each grid tube core 14 on the outside of the grid tube core 14, and a rotatable rotating round seat 202 is radially pressed outward against the inner side of the axial upper end of the grid tube core 14, so that the rotating round seat 202 rotates with the axial upper end of the grid tube core 14, avoiding the situation where the rotating round seat 202 is fixed and affects the rotation of the axial upper end of the grid tube core 14 through friction, which is more conducive to the torsional operation of the grid tube core 14.

[0028] See also Figure 5 According to one embodiment of the present application, the upper end of the rotating circular seat 202 has an annular platform 204 with the same diameter as the fixed circular seat 201, and the axial upper end of the grid tube core 14 is sleeved on the outer peripheral side of the upper end of the rotating circular seat 202. The diameter of the rotating circular seat 202 below the annular platform 204 is smaller than the diameter of the annular platform 204. In this design, considering that the axial middle part of the grid tube core 14 will radially shrink inward when it is twisted, the part of the rotating circular seat 202 below the annular platform 204 can just leave a shrinking space for the shrinking part of the grid tube core 14.

[0029] See also Figure 4 and Figure 5According to one embodiment of the present application, the end surface of the upper end of the rotating round seat 202 forms a socket 205 that is recessed downward along the axial direction of the rotating round seat 202, and the upper end of the rotating round seat 202 also forms a plurality of slits 206 that penetrate the outer surface of the rotating round seat 202 in the radial and axial directions of the rotating round seat 202, and each slit 206 is connected to the socket 205, so that the upper end of the rotating round seat 202 forms a plurality of expansion petals through the plurality of slits 206, and the first torsion block 404 is provided with a plurality of expansion petals corresponding to the number of the grid core through-set 200 above the surface for clamping the grid core 14. A plurality of movable rods 405 are installed on the first torsion block 404 so as to be movable along the second horizontal straight line direction Y. When the first torsion block 404 is aligned with the insertion hole 205 and moves downward, each movable rod 405 can be inserted into the insertion hole 205 of the rotating round seat 202 of each corresponding grid tube core through-set 200 and each expansion petal expands radially outward toward the rotating round seat 202. When the movable rod 405 is inserted into the insertion hole 205, the first torsion block 404 is used to clamp the surface of the grid tube core 14 against the grid tube core 14. When the torsion operation is performed, the movable rod 405 The rod 405 is inserted into the insertion hole 205 and the first torsion block 404 is pressed against the grid tube core 14. Then, the second torsion block 504 can be driven to press against the grid tube core 14. The multiple expansion petals expand radially outward toward the rotating circular seat 202 so as to be pressed more tightly against the inner side of the axial upper end of the grid tube core 14, so that the axial upper end of the grid tube core 14 is more firmly clamped between the outer peripheral side of the rotating circular seat 202 and the first torsion block 404 and the second torsion block 504, which is more conducive to the first torsion block 404 and the second torsion block 504 relative to each other in the second horizontal straight line direction Y. The movable rod 405 can be installed on the first torsion block 404 so as to move along the second horizontal straight direction Y to rub the axial upper end of the grid tube core 14. This is because if the first torsion block 404 is designed to move in the second horizontal straight direction Y, the first torsion block 404 will be displaced in the second horizontal straight direction Y relative to the axis of the socket 205 of the rotating round seat 202, and the movable rod 405 can move along the second horizontal straight direction Y to ensure that the displacement is not restricted by the rotating round seat 202. The lower end of the movable rod 405 forms a conical head to facilitate insertion into the socket 205.

A plurality of movable rods 405 are arranged below the sliding plate 407. The movable rods 405 are preferably rotatably connected to the bottom of the sliding plate 407 along their central axis to facilitate synchronous rotation with the rotating round seat 202. The sliding plate 407 can also cooperate with an elastic member (such as a spring 408) inside the sliding groove 406, so that the first torsion block 404 is not performing a torsion operation. The sliding plate 407 is maintained in the initial position under the elastic member and is maintained in the initial position after the first torsion block 404 completes the torsion operation, which is convenient for positioning the first torsion block 404, the movable rod 405 and the rotating round seat 202. Specifically, the sliding plate 407 is connected with a spring sleeve rod 409 inside the sliding groove 406, and the elastic expansion and contraction direction of the spring 408 is along the second horizontal straight line direction Y. The first end of the spring 408 abuts against the inner wall corresponding to the sliding groove 406, and the second end of the spring 408 is sleeved on the spring sleeve rod 409 and stops the spring sleeve rod 409.
