In the working state, the wings 126 are subjected to the elastic force of the spring 127, and the first positioning fork 123 clamps the resistance in the placing cavity 124. In addition, the mounting table 110 is sequentially divided into a feeding station, a shearing station, a first bending station, a second bending station, a third bending station, a fourth bending station and a discharging station around the rotating direction of the rotating part 112.

The heating member 226 is arranged on the second support plate 229, and in this embodiment, the heating member 226 is a heating rod. The material shifting rod 222 continuously drags the material belt on the material disc 210 out under the driving of the lifting cylinder 222a and the transverse moving cylinder 222b, the material belt passes through the conveying channel 225 and is heated at the heating member 226, so that the adhesive between the resistor and the material belt is softened, and the resistor is more easily taken off from the material belt. When the material belt is shifted to the discharging end of the conveying plate 221 under the shifting of the material shifting rod 222, the shears 224 can cut it, and the cut waste material directly falls into the collecting box 223. In addition, a pair of clamping wheels 211 are arranged between the material disc 210 and the conveying plate 221, the height of the clamping wheels 211 is consistent with the height of the conveying channel 225, and the clamping wheels 211 can fix the material belt between the material disc 210 and the conveying plate 221, so that the material belt can smoothly enter the conveying channel 225. A pressing cylinder 212 is further arranged at the middle section of the conveying channel 225, and the heating rod is arranged between the pressing cylinder 212 and the material shifting rod 222. The pressing cylinder 212 can fix the material belt, so as to prevent the material belt from being dragged away from the conveying channel 225 during the process of the transferring assembly 300 taking off the resistor from the material belt.

[0065] Further, the feeding assembly 200 and the feeding station are provided with a transfer assembly 300 for transferring the resistors from the tape to the jig 120. The transfer assembly 300 comprises a first material moving mechanism 310 for taking the resistors from the tape and a second material moving mechanism 320 for transferring the resistors to the jig 120. The first material moving mechanism 310 comprises a first support 311, a first guide plate 312 vertically arranged on the first support 311, a rotating base 313 arranged beside the first guide plate 312, and a first material moving clamp jaw 314 rotatably arranged on the rotating base 313. The first guide plate 312 is provided with a first guide hole 315 in the shape of an inverted "L", the rotating base 313 is provided with a mounting hole (not shown in the figure), the mounting hole is provided with a linkage shaft 317 in the shape of "Z", one end of the linkage shaft 317 is fixed to the first material moving clamp jaw 314, and the other end of the linkage shaft 317 is arranged in the first guide hole 315. Further, a second sliding assembly (318, 319) is arranged between the rotating base 313 and the first support 311, the second sliding assembly comprises a second sliding block 319 arranged at the bottom of the rotating base 313 and a second sliding rail 318 arranged on the first support 311, the second sliding block 319 can slide on the second sliding rail 318 under the drive of a drive cylinder 316, thereby driving the rotating base 313 to move on the first support 611. During the movement of the rotating base 313 on the first support 611, the linkage shaft 317 moves in the first guide hole 315, and is rotated at the turning part of the first guide hole 315 under the action of the supporting force of the inner wall of the first guide hole 315, thereby changing from the original horizontal movement to vertical movement. During this process, the end of the linkage shaft 317 arranged in the first guide hole 315 is rotated under the action of the rotating torque, thereby driving the first material moving clamp jaw 314 at the other end of the linkage shaft 317 to rotate from the original horizontal position to the vertical position, so as to facilitate the second material moving clamp jaw 323 to pick up the resistor from the first material moving clamp jaw 314. The second material moving mechanism 320 comprises a second support 321, a second guide plate 322 vertically arranged on the second support 321, and a second material moving clamp jaw 323 suspended on the second guide plate 322. The second guide plate 322 is provided with a second guide hole 324 in the shape of a semicircle, and is provided with a "U"-shaped push rod 325 and a rotary drive member 325a for driving the push rod 325 to rotate. The second material moving clamp jaw 323 is provided with a connecting rod 326, and the second material moving clamp jaw 323 is suspended on the second guide plate 322 through the connecting rod 326 passing through the push rod 325 and the second guide hole 324. The second material moving clamp jaw 323 is provided with a mounting seat 327, and the mounting seat 327 and the second guide plate 322 are provided with a lifting sliding assembly 328 and a horizontal sliding assembly 329.The horizontal sliding assembly 329 comprises a horizontal sliding rail 329a arranged on the second guide plate 322 and a horizontal sliding block 329b slidably arranged on the horizontal sliding rail 329a; the vertical sliding assembly 328 comprises a vertical sliding rail 328a arranged on the mounting seat 327 and a vertical sliding block 328b arranged on the horizontal sliding block 329b. When the rotating driving member 325a drives the rotating lever 325 to rotate, the connecting rod 326 is moved in the second guide hole 324, thereby driving the second material moving clamp jaw 323 to move from one side of the second guide plate 322 to the other side. It should be noted that when the second material moving clamp jaw 323 moves from one side of the guide plate to the other side, the resistance is transferred from the first material moving clamp jaw 314 to the jig 120. That is, when the second material moving clamp jaw 323 is at one end of the second guide hole 324, it is just above the first material moving clamp jaw 314, and when the second material moving clamp jaw 323 is at the other end of the second guide hole 324, it is just above the jig 120. That is, the diameter of the semicircle of the second guide hole 324 is just the distance between the first material moving clamp jaw 314 in the vertical state and the jig 120. The rotating driving member 325a can be a rotating motor, a rotating cylinder or a rotating hydraulic cylinder, and in this embodiment, the rotating driving member 325a is a rotating motor.

[0066] In addition, the feeding station is provided with a first jig opening mechanism 410 for opening the jig 120. Specifically, the first jig opening mechanism 410 comprises a first driving member 411 fixed to the mounting table 110 and a second connecting plate 412 vertically arranged at the output end of the first driving member 411, and the second connecting plate 412 is connected to the output end of the first driving member 411 by adjusting bolts. The first driving member 411 is a telescopic cylinder, and the output end is a plate-shaped structure, and the second connecting plate 412 can adjust the distance between the output end of the first driving member 411 by adjusting the bolts. When the jig 120 rotates with the rotating part 112 to the first jig opening mechanism 410, the first connecting plate 122 is just between the output end of the first driving member 411 and the second connecting plate 412, and the first driving member 411 drives the second connecting plate 412 to retreat, thereby driving the first connecting plate 122 on the jig 120 to move backward, thereby driving the first positioning fork 123 on the first connecting plate 122 to move away from the placement cavity 124, so that the second material moving clamp jaw 323 can put the resistance into the placement cavity 124. After the second material moving clamp jaw 323 puts the resistance into the placement cavity 124, the first driving member 411 drives the second connecting plate 412 to move forward, and the first connecting plate 122 is reset under the action of the elastic force of the spring 127 in the base 121, thereby fixing the resistance in the jig 120 for subsequent operation on the resistance.
