Description

Technical Field

[0001] This invention relates to the field of resistor manufacturing technology, and more particularly to equipment and processing methods for processing resistor leads. Background Technology

[0002] Resistors, inductors, and capacitors are common electronic components, and most circuit boards require them. Resistors, once manufactured, have two leads. For ease of transport and storage, the ends of these leads are fixed to two parallel sealing strips, with multiple resistors evenly distributed on the strips forming a resistor bar. Then, depending on the needs of different equipment, the two leads are manufactured to different lengths and shapes. In industrial production, resistor workpieces require cutting, bending, and shaping to achieve the desired structural shape. However, current production processes require long assembly lines with corresponding cutting and bending machines. While this results in high output, the equipment occupies a large area, is costly, and has low production efficiency per unit.

[0003] In view of this, it is necessary to propose equipment and processing methods for resistor pin fabrication to solve the above problems. Summary of the Invention

[0020] The present invention also provides a processing method using the apparatus for processing resistor leads as described above, comprising the following steps:

[0021] S01: The material transfer rod on the conveying mechanism continuously feeds the material strip on the tray into the conveying channel by moving the material strip;

[0022] S02: The first transfer mechanism in the transfer assembly removes the resistor from the strip, and then the second transfer mechanism in the transfer assembly transfers the resistor from the first transfer mechanism to the fixture; at the same time, the first fixture opening mechanism opens the fixture;

[0023] S03: The rotating part on the mounting table rotates, transferring the fixture from the loading station to the shearing station, and the shearing mechanism cuts the leads on the resistor.

An unloading mechanism is located above the unloading station. The rotating part is equipped with a fixture for loading resistors, which can rotate with the rotating part to each station for corresponding operations. Specifically, the conveying mechanism transports the strip from the tray, and then the transfer component removes the resistors from the strip and transfers them to the fixture. The fixture, along with the rotating part, first reaches the shearing station, where the shearing mechanism cuts the leads of the resistors on the fixture. Then, the fixture, along with the rotating part, reaches the first bending station, the second bending station, the third bending station, and the fourth bending station, where the first bending mechanism, the second bending mechanism, the third bending mechanism, and the fourth bending mechanism bend the two leads of the resistors into shape. Finally, the rotating part transports the fixture to the unloading station, where the unloading mechanism removes the resistors from the fixture and transports them to the next process. This invention integrates various mechanisms around the mounting platform by using a mounting platform and a shearing mechanism, a first bending mechanism, a second bending mechanism, a third bending mechanism, a fourth bending mechanism, and a feeding mechanism arranged sequentially around the rotation direction of the rotating part. This shortens the length of the production line and eliminates the need for additional mechanisms such as cutting machines and bending machines, effectively solving the technical problems of large footprint and low efficiency in existing equipment used for resistor pin processing.

[0063] Please refer to the appendix. Figure 1 To be continued Figure 18This invention provides an apparatus for processing resistor leads, including a worktable 100, on which a mounting platform 110 is disposed. The mounting platform 110 includes a fixed part 111 and a rotating part 112 rotatably disposed below the fixed part 111. Specifically, in this embodiment, the mounting platform 110 is a two-layer disc structure, with the fixed part 111 as the upper layer and the rotating part 112 as the lower layer. A drive motor (not shown in the figure) is disposed at the bottom of the rotating part 112 to drive the rotating part 112 to rotate, and a plurality of fixtures 120 are evenly disposed around the circumference of the rotating part 112. Specifically, in this embodiment, a total of 8 fixtures 120 are disposed on the rotating part 112. The fixture 120 includes a base 121, an "L"-shaped first connecting plate 122 slidably mounted on the base 121, and a first positioning fork 123 fixed to the first connecting plate 122. A spring 127 is provided between the base 121 and the first connecting plate 122. A placement cavity 124 for placing a resistor is provided on the base 121. Specifically, the base 121 is concave and has a first slide rail 125. The first connecting plate 122 is slidably mounted on the first slide rail 125. Wing plates 126 are provided on both sides of the first connecting plate 122, and the spring 127 is located between the wing plates 126 and the base 121. In the working state, the wing plates 126 are subjected to the elastic force of the spring 127, and the first positioning fork 123 holds the resistor in place within the placement cavity 124. In addition, the mounting table 110 is divided into a loading station, a shearing station, a first bending station, a second bending station, a third bending station, a fourth bending station, and a unloading station in sequence around the rotation direction of the rotating part 112.

[0064] The feeding station is equipped with a feeding assembly 200 for feeding resistance materials. The feeding assembly 200 includes a material tray 210 for winding the material strip and a conveying mechanism 220 for conveying the material strip. Specifically, the conveying mechanism 220 includes a material transfer plate 221, a material transfer rod 222 disposed above the material transfer plate 221 for moving the material strip, a collection box 223 disposed at the discharge end of the material transfer plate 221, and a scissor 224 disposed between the material transfer plate 221 and the collection box 223. A conveying channel 225 for feeding the material strip is formed on the material transfer plate 221, and a heating element 226 for heating the material strip is disposed in the middle of the conveying channel 225. In addition, the conveying mechanism 220 also includes a fourth support 227, on which the material transfer plate 221 is fixed. A first support plate 228 and a second support plate 229 are vertically arranged on the fourth support 227. The first support plate 228 is equipped with a lifting cylinder 222a for driving the material transfer rod 222 to rise and fall, and a lateral cylinder 222b for driving the material transfer rod 222 to move laterally. The lifting cylinder 222a is located at the output end of the lateral cylinder 222b, and the material transfer rod 222 is located at the output end of the lifting cylinder 222a. A heating element 226 is located on the second support plate 229. In this embodiment, the heating element 226 is a heating rod. Driven by the lifting cylinder 222a and the lateral cylinder 222b, the material transfer rod 222 continuously pulls the material strip from the material tray 210. The material strip passes through the conveying channel 225 and is heated at the heating element 226, softening the adhesive between the resistor and the material strip, making it easier to remove the resistor from the material strip. When the conveyor belt moves to the discharge end of the transfer plate 221 under the action of the transfer rod 222, the shears 224 can cut it, and the cut waste material falls directly into the collection box 223. In addition, a pair of clamping wheels 211 are provided between the tray 210 and the transfer plate 221, and the height of the clamping wheels 211 is the same as the height of the conveying channel 225. The clamping wheels 211 can fix the conveyor belt between the tray 210 and the transfer plate 221, allowing it to smoothly enter the conveying channel 225. A pressing cylinder 212 is also provided in the middle section of the conveying channel 225, and a heating rod is positioned between the pressing cylinder 212 and the transfer rod 222. The pressing cylinder 212 can fix the conveyor belt, preventing the transfer assembly 300 from dragging the conveyor belt away from the conveying channel 225 during the process of removing the resistor from the conveyor belt.

[0065] In addition, a transfer assembly 300 is provided between the feeding assembly 200 and the feeding station to transfer resistors from the material strip to the fixture 120. The transfer assembly 300 includes a first transfer mechanism 310 for removing resistors from the material strip and a second transfer mechanism 320 for transferring resistors to the fixture 120. The first transfer mechanism 310 includes a first support 311, a first guide plate 312 vertically mounted on the first support 311, a rotating seat 313 mounted on the side of the first guide plate 312, and a first transfer gripper 314 rotatably mounted on the rotating seat 313. The first guide plate 312 has an inverted "L"-shaped first guide hole 315. The rotating seat 313 has a mounting hole (not shown in the figure) with a "Z"-shaped linkage shaft 317 installed in the mounting hole. One end of the linkage shaft 317 is fixed to the first transfer gripper 314, and the other end is located in the first guide hole 315. Furthermore, a second sliding assembly (318, 319) is provided between the rotating seat 313 and the first support 311. The second sliding assembly includes a second slider 319 disposed at the bottom of the rotating seat 313 and a second slide rail 318 disposed on the first support 311. The second slider 319 can slide on the second slide rail 318 under the drive of the drive cylinder 316, thereby driving the rotating seat 313 to move on the first bracket 611. During the movement of the rotating seat 313 on the first bracket 611, the linkage shaft 317 moves within the first guide hole 315 and rotates at the turning point of the first guide hole 315 under the support force of the inner wall of the first guide hole 315, changing from the original horizontal movement to vertical movement. During this process, one end of the linkage shaft 317, located within the first guide hole 315, rotates under the influence of rotational torque, thereby causing the first transfer gripper 314 at the other end of the linkage shaft 317 to rotate from its original horizontal position to a vertical position, so that the second transfer gripper 323 can pick up the resistor from the first transfer gripper 314. The second transfer mechanism 320 includes a second support 321, a second guide plate 322 vertically mounted on the second support 321, and a second transfer gripper 323 suspended on the second guide plate 322. The second guide plate 322 has a semi-circular second guide hole 324, a U-shaped lever 325, and a rotary drive component 325a that drives the lever 325 to rotate. The second transfer gripper 323 has a connecting rod 326, which passes through the lever 325 and the second guide hole 324 to suspend it on the second guide plate 322. The second material transfer gripper 323 is provided with a mounting base 327, and a lifting sliding assembly 328 and a transverse sliding assembly 329 are provided between the mounting base 327 and the second guide plate 322.The transverse sliding assembly 329 includes a transverse slide rail 329a disposed on the second guide plate 322 and a transverse slider 329b slidably disposed on the transverse slide rail 329a; the lifting sliding assembly 328 includes a lifting slide rail 328a disposed on the mounting base 327 and a lifting slider 328b disposed on the transverse slider 329b. When the lever 325 rotates under the drive of the rotary drive member 325a, it can drive the connecting rod 326 to move within the second guide hole 324, thereby driving the second transfer gripper 323 to move from one side of the second guide plate 322 to the other side. It should be noted that when the second transfer gripper 323 moves from one side of the guide plate to the other side, it precisely transfers the resistance from the first transfer gripper 314 to the fixture 120. That is, when the second transfer jaw 323 is at one end of the second guide hole 324, it is directly above the first transfer jaw 314; and when the second transfer jaw 323 is at the other end of the second guide hole 324, it is directly above the fixture 120. In other words, the semi-circular diameter of the second guide hole 324 is exactly the distance between the first transfer jaw 314 and the fixture 120 when the first transfer jaw is in its vertical position. The rotary drive component 325a can be a rotary motor, a rotary cylinder, or a rotary hydraulic cylinder, etc. In this embodiment, the rotary drive component 325a is a rotary motor.

[0066] In addition, a first fixture opening mechanism 410 for opening the fixture 120 is provided at the loading station. Specifically, the first fixture opening mechanism 410 includes a first driving member 411 fixed on the mounting platform 110 and a second connecting plate 412 vertically disposed at the output end of the first driving member 411. 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 with a plate-like structure at its output end. The distance between the second connecting plate 412 and the output end of the first driving member 411 can be adjusted by adjusting bolts. When the fixture 120 rotates with the rotating part 112 to the first fixture opening mechanism 410, the first connecting plate 122 is positioned between the output end of the first driving member 411 and the second connecting plate 412. The first driving member 411 drives the second connecting plate 412 backward, thereby moving the first connecting plate 122 on the fixture 120 backward. This causes the first positioning fork 123 on the first connecting plate 122 to move away from the placement cavity 124, allowing the second transfer gripper 323 to place the resistor into the placement cavity 124. After the second transfer gripper 323 places the resistor into the placement cavity 124, the first driving member 411 drives the second connecting plate 412 forward. The first connecting plate 122 is reset by the elastic force of the spring 127 in the base 121, fixing the resistor in the fixture 120 for subsequent operation. It is understood that the first driving member 411, in addition to the telescopic cylinder form given in this embodiment, can also be a telescopic motor or a telescopic hydraulic cylinder, etc.

[0067] The shearing station is equipped with a shearing mechanism 500 for shearing resistor leads. Specifically, the shearing mechanism 500 includes a mounting box 510, a mounting block 520 that is laterally movable within the mounting box 510, a shearing component 530 mounted on the mounting block 520, and an exhaust fan 540 located below the mounting box 510. The exhaust fan 540 is connected to the mounting box 510 via a suction pipe 541. A third slide rail (not shown in the figure) is provided inside the mounting box 510. The mounting block 520 can slide on the third slide rail under the drive of a drive cylinder 521. During the sliding process of the mounting block 520 within the mounting box 510, the shearing component 530 can cut off the leads on the resistor. Specifically, the shearing component 530 can be a steel bar or a blade. In this embodiment, the shearing component 530 is a high-hardness steel bar, which can cut off the resistor leads under the drive of the drive cylinder 521. The exhaust fan 540 can use the suction pipe 541 to absorb and remove the waste material cut out inside the installation box 510.

[0068] A first bending mechanism 610 for bending the first lead of a resistor to a first angle is provided next to the first bending station; a second bending mechanism 620 for bending the first lead of a resistor to a second angle is provided next to the second bending station; a third bending mechanism 630 for bending the second lead of a resistor to a third angle is provided next to the third bending station; and a fourth bending mechanism 640 for bending the second lead of a resistor to a fourth angle is provided next to the fourth bending station. The first bending mechanism 610 includes a first support 611, a first push rod 612 disposed on the first support 611, and a first lateral movement drive 613 for driving the first push rod 612 to move laterally. A first guide groove 614 is vertically formed on the first push rod 612. Driven by the first lateral movement drive 613, the first push rod 612 bends the first lead of the resistor from its original vertical state to a horizontal state. During the process of the first push rod 612 pushing the first lead down, the first guide groove 614 on the first push rod 612 can position and guide the first lead. When the first push rod 612 gradually approaches the first pin under the drive of the first lateral drive member 613, the first pin will first enter the first guide groove 614. Then, under the continued drive of the first lateral drive member 613, the first pin in the first guide groove 614 will bend under the force of the first push rod 612. In this embodiment, the first lateral drive member 613 is a telescopic cylinder. It is worth mentioning that during the process of pushing the first pin down, the first positioning fork 123 and the first push rod 612 together clamp the first pin. The second bending mechanism 620 includes a second bracket 621, a first mounting plate 622 disposed on the second bracket 621, a second lateral movement drive 623 for driving the first mounting plate 622 to move laterally, a second push rod 624 disposed on the first mounting plate 622, and a longitudinal movement drive 625 for driving the second push rod 624 to move longitudinally. The longitudinal movement drive 625 is fixed on the first mounting plate 622. A first guard rod 626 is disposed on one end of the first mounting plate 622 opposite to the second lateral movement drive 623. The second push rod 624 is shaped like a "7" and a second guide groove 627 is formed at its bottom. During the bending process of the first lead of the resistor by the second bending mechanism 620, the first mounting plate 622 and its first guard rod 626 and second push rod 624 gradually approach the resistor under the drive of the second transverse drive member 623. The first guard rod 626 first contacts and holds the first lead, which is in a horizontal state. Then, the second push rod 624 bends the first lead under the drive of the longitudinal drive member 625. During the bending process, the first lead is squeezed and gradually comes into contact with the second guide groove 627. The angle formed by the second push rod 624 on the first lead is the shape of the second guide groove 627. When the second push rod 624 squeezes the first lead, the first guard rod 626 can fix the first lead to prevent deformation of the first lead due to the force of the second push rod 624 on one side.The second lateral movement drive 623 and the longitudinal movement drive 625 are both telescopic cylinders. The third bending mechanism 630 includes a third bracket 631, a second positioning fork 632 mounted on the third bracket 631, a second mounting plate 633 fixed to the fixing part 111, a third push rod 634 mounted on the second mounting plate 633, and a third lateral movement drive 635 that drives the third push rod 634 to move laterally. A third guide groove 636 is vertically formed on the third push rod 634. During the bending process of the second lead of the resistor by the third bending mechanism 630, the second positioning fork 632 approaches and fixes the resistor under the drive of the drive cylinder. The third push rod 634 bends the second lead from its original vertical state to a horizontal state under the drive of the third lateral movement drive 635. During the process of the third push rod 634 pushing the second lead down, the third guide groove 636 on the third push rod 634 can position and guide the second lead. When the third push rod 634 gradually approaches the second pin under the drive of the third lateral movement drive member 635, the second pin will first enter the third guide groove 636. Then, under the continued drive of the third lateral movement drive member 635, the second pin in the third guide groove 636 will bend under the force of the third push rod 634. In this embodiment, the third lateral movement drive member 635 is a telescopic cylinder. The fourth bending mechanism 640 includes a fourth bracket 641, a fourth push rod 642 disposed on the fourth bracket 641, a fourth lateral movement drive member 643 that drives the fourth push rod 642 to move laterally, a second guard rod 644 disposed on the fourth bracket 641, and a first lifting drive member 645 that drives the second guard rod 644 to rise and fall. The bottom of the second guard rod 644 has a fourth guide groove 646. During the bending process of the second pin of the resistor by the fourth bending mechanism 640, the second guard rod 644 gradually approaches the resistor under the drive of the first lifting drive member 645. The second guard rod 644 first contacts and holds the second pin in a horizontal position. Then, the fourth push rod 642 bends the second pin under the drive of the fourth lateral drive member 643. During the bending process, the second pin is squeezed and gradually comes into contact with the fourth guide groove 646. The angle formed by the fourth push rod 642 on the second pin is the shape of the fourth guide groove 646. When the fourth push rod 642 squeezes the second pin, the second guard rod 644 can fix the second pin to prevent deformation of the second pin due to the force of the fourth push rod 642 on one side. Both the fourth lateral drive member 643 and the first lifting drive member 645 are telescopic cylinders.

[0069] The unloading station includes an unloading mechanism 700 for unloading bent resistors. The unloading mechanism 700 includes a third support 710, a gripper 720 mounted on the third support 710, a second lifting drive 730 for lifting the gripper 720, and a lateral linear module 740 for moving the gripper 720 laterally. The second lifting drive 730 is located at the output end of the lateral linear module 740. Driven by the second lifting drive 730 and the lateral linear module 740, the gripper 720 can remove the resistor from the fixture 120 and transfer it to the next process. The second lifting drive 730 can be a lifting cylinder 222a, a lifting motor, or a lifting hydraulic cylinder, etc. Specifically, in this embodiment, the second lifting drive 730 is a lifting cylinder 222a. Furthermore, the unloading station also includes a second fixture opening mechanism 420 for opening the fixture 120. The second opening fixture mechanism 420 includes a second driving member 421 fixed on the mounting platform 110 and a third connecting plate 422 vertically disposed at the output end of the second driving member 421. The third connecting plate 422 is connected to the output end of the second driving member 421 by adjusting bolts. The second driving member 421 is a telescopic cylinder with a plate-like output end. The distance between the third connecting plate 422 and the output end of the second driving member 421 can be adjusted by adjusting bolts. When the fixture 120 rotates with the rotating part 112 to the second opening fixture mechanism 420, the first connecting plate 122 is positioned between the output end of the second driving member 421 and the third connecting plate 422. The second driving member 421 drives the third connecting plate 422 backward, thereby moving the first connecting plate 122 on the fixture 120 backward. This causes the first positioning fork 123 on the first connecting plate 122 to move away from the placement cavity 124, allowing the material handling gripper 720 to remove the resistor from the placement cavity 124. After the material handling gripper 720 removes the resistor from the placement cavity 124, the second driving member 421 drives the third connecting plate 422 to move forward, and the first connecting plate 122 is reset by the pressure of the spring 127 in the base 121. It can be understood that the second driving member 421, in addition to the telescopic cylinder form given in this embodiment, can also be a telescopic motor or a telescopic hydraulic cylinder, etc.

[0070] The present invention also provides a processing method using the apparatus for processing resistor leads as described above, comprising the following steps:

[0071] S01: The transfer rod 222 on the conveying mechanism 220 continuously feeds the material strip on the tray 210 into the conveying channel 225 by actuating the material strip. Specifically, the transfer rod 222 continuously pulls the material strip out of the tray 210 under the drive of the lifting cylinder 222a and the lateral cylinder 222b. The material strip passes through the conveying channel 225 and is heated at the heating element 226. When the material strip moves to the discharge end of the conveyor plate 221 under the actuation of the transfer rod 222, the shears 224 can cut it, and the cut waste material falls directly into the collection box 223.

[0072] S02: The first transfer mechanism 310 in the transfer assembly 300 removes the resistor from the strip, and then the second transfer mechanism 320 in the transfer assembly 300 transfers the resistor from the first transfer mechanism 310 to the fixture 120; simultaneously, the first fixture opening mechanism 410 opens the fixture 120. Specifically, the second slider 319 slides on the second slide rail 318 under the drive of the drive cylinder, causing the rotating seat 313 to move on the first support 611. During the movement of the rotating seat 313 on the first support 611, the linkage shaft 317 moves within the first guide hole 315 and rotates at the turning point of the first guide hole 315 due to the supporting force of the inner wall of the first guide hole 315. During this process, the first transfer gripper 314 at the other end of the linkage shaft 317 rotates from the original horizontal position to the vertical position. The second transfer gripper 323 removes the resistor from the first transfer gripper 314. The lever 325 rotates under the drive of the rotary drive 325a, and the connecting rod 326 moves within the second guide hole 324, thereby moving the second transfer gripper 323 from above the first transfer gripper 314 to above the fixture 120. Simultaneously, when the fixture 120 rotates with the rotating part 112 to the first fixture opening mechanism 410, the first connecting plate 122 is positioned between the output end of the first drive member 411 and the second connecting plate 412. The first drive member 411 drives the second connecting plate 412 backward, thereby moving the first connecting plate 122 on the fixture 120 backward. This causes the first positioning fork 123 on the first connecting plate 122 to move away from the placement cavity 124, allowing the second transfer gripper 323 to place the resistor into the placement cavity 124. After the second transfer gripper 323 places the resistor into the placement cavity 124, the first drive member 411 drives the second connecting plate 412 to move forward, and the first connecting plate 122 is reset by the pressure of the spring 127 in the base 121.

[0073] S03: The rotating part 112 on the mounting table 110 rotates, transferring the fixture 120 from the loading station to the shearing station, and the shearing mechanism 500 cuts the leads on the resistor. Specifically, the mounting block 520 can slide on the third slide rail under the drive of the drive cylinder. During the sliding process of the mounting block 520 in the mounting box 510, the shearing part 530 can cut off the leads on the resistor.

[0074] S04: The rotating part 112 continues to rotate, transferring the fixture 120 from the shearing station to the first bending station. The first bending mechanism 610 bends the first lead of the resistor to a first angle. Specifically, the first push rod 612, driven by the first lateral drive member 613, bends the first lead of the resistor from its original vertical state to a horizontal state.

[0075] S05: The rotating part 112 continues to rotate, transferring the fixture 120 from the first bending station to the second bending station. The second bending mechanism 620 bends the first pin of the resistor to a second angle. Specifically, the first mounting plate 622 and its first guard rod 626 and second push rod 624 gradually approach the resistor under the drive of the second transverse drive member 623. The first guard rod 626 first contacts the first pin in a horizontal state and holds it against it. Then, the second push rod 624 bends the first pin under the drive of the longitudinal drive member 625. During the bending process, the first pin is squeezed and gradually comes into contact with the second guide groove 627. The angle formed by the second push rod 624 on the first pin is the shape of the second guide groove 627.

[0076] S06: The rotating part 112 continues to rotate, transferring the fixture 120 from the second bending station to the third bending station. The third bending mechanism 630 bends the second lead of the resistor to the first angle. Specifically, the third push rod 634, driven by the third lateral drive member 635, bends the second lead from its original vertical state to a horizontal state.

[0077] S07: The rotating part 112 continues to rotate, transferring the fixture 120 from the third bending station to the fourth bending station. The fourth bending mechanism 640 bends the second pin of the resistor to a second angle. Specifically, the second guard rod 644 gradually approaches the resistor under the drive of the first lifting drive member 645. The second guard rod 644 first contacts the second pin, which is in a horizontal state, and holds it against it. Then, the fourth push rod 642 bends the second pin under the drive of the fourth lateral drive member 643. During the bending process, the second pin is squeezed and gradually comes into contact with the fourth guide groove 646. The angle formed by the fourth push rod 642 on the second pin is the shape of the fourth guide groove 646.

[0078] S08: The rotating part 112 continues to rotate, transferring the fixture 120 from the fourth bending station to the unloading station. The second fixture opening mechanism 420 opens the fixture 120, and at the same time, the unloading station removes the resistor from the fixture 120. Specifically, the picking gripper 720, driven by the second lifting drive 730 and the lateral linear module 740, can remove the resistor from the fixture 120 and transfer it to the next process. At the same time, when the fixture 120 rotates with the rotating part 112 to the second fixture opening mechanism 420, the first connecting plate 122 is exactly between the output end of the second drive 421 and the third connecting plate 422. The second drive 421 drives the third connecting plate 422 to move backward, thereby moving the first positioning fork 123 on the first connecting plate 122 away from the placement cavity 124, so that the picking gripper 720 can remove the resistor from the placement cavity 124. After the material handling gripper 720 removes the resistor from the placement cavity 124, the second driving member 421 drives the third connecting plate 422 to move forward, and the first connecting plate 122 is reset by the pressure of the spring 127 in the base 121.

[0079] S09: The rotating part 112 continues to rotate to transfer the jig 120 back to the loading station, repeating S03 to S08.

[0080] In this application, the equipment for processing resistor leads includes a mounting table 110, which includes a fixed part 111 and a rotating part 112. The mounting table 110 is divided into a loading station, a shearing station, a first bending station, a second bending station, a third bending station, a fourth bending station, and a unloading station. A loading assembly 200 and a transfer assembly 300 are provided beside the loading station. A shearing mechanism 500 is provided above the shearing station. A first bending mechanism 610, a second bending mechanism 620, a third bending mechanism 630, and a fourth bending mechanism 640 are provided beside the first bending station. An unloading mechanism 700 is provided above the unloading station. The rotating part 112 is equipped with a fixture 120 for loading resistors. The fixture 120 can rotate with the rotating part 112 to each station for corresponding operations. Specifically, the conveying mechanism 220 conveys the strip on the tray 210, and then the transfer assembly 300 removes the resistors from the strip and transfers them to the fixture 120. The fixture 120, along with the rotating part 112, first reaches the shearing station, where the shearing mechanism 500 cuts the leads of the resistors on the fixture 120. Then, the fixture 120, along with the rotating part 112, reaches the first bending station, the second bending station, the third bending station, and the fourth bending station, where the first bending mechanism 610, the second bending mechanism 620, the third bending mechanism 630, and the fourth bending mechanism 640 bend the two leads of the resistors into shape. Finally, the rotating part 112 transports the fixture 120 to the unloading station, where the unloading mechanism 700 removes the resistors from the fixture 120 and transports them to the next process. The present invention integrates the following mechanisms around the mounting platform 110 by using a mounting platform 110 and a shearing mechanism 500, a first bending mechanism 610, a second bending mechanism 620, a third bending mechanism 630, a fourth bending mechanism 640, and a feeding mechanism 700 arranged sequentially on the worktable 100 around the rotation direction of the rotating part 112. This shortens the length of the production line and eliminates the need for other mechanisms such as cutting machines and bending machines, effectively solving the technical problems of large footprint and low working efficiency in existing equipment used for resistor pin processing.
