Existing resistor lead bending devices mostly employ a structure design where feeding and bending are driven independently. The core technical problem with this design is the poor coordination between the feeding and bending actions.

[0022] In this invention, the terms "first," "second," etc., are used for descriptive purposes only and do not specifically refer to any order or sequence, nor are they intended to limit the invention. They are merely used to distinguish protective components or operations described using the same technical terms, and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0023] Example 1: Please refer to Figures 1-2 The present invention provides a technical means including a mounting base 1, on which a bending seat 2 and a feeding tray 12 are mounted. Resistors 10 in resistor storage box 9 are guided by guide plate 11 and fed to bending seat 2 via feeding tray 12. A linkage component 8 is mounted on the outer wall of resistor storage box 9. A support plate 25 is fixedly provided at the output end of bending cylinder 5. A bending pusher assembly 6 is mounted at the bottom of support plate 25. Bending cylinder 5 bends the leads of resistor 10 in bending seat 2 by pushing bending pusher assembly 6 down.

[0024] Preferably, the vertical section of the L-shaped bracket 4 is fixedly connected to the mounting base 1, and a bending cylinder 5 is fixedly installed on its horizontal section. The fixing column 7 is fixedly connected to the mounting base 1, and the resistor storage box 9 is fixedly connected to the fixing column 7.

[0025] Preferably, two sets of rotating supports 3 are symmetrically fixed on the mounting base 1. The feeding tray 12 is rotatably installed between the two sets of rotating supports 3. A drive motor 24 is installed on the side wall of one set of rotating supports 3, and the output shaft of the drive motor 24 is fixedly connected to the feeding tray 12. The feeding tray 12 is provided with several sets of resistor slots 13. One end of the guide plate 11 is fixedly connected to the bottom of the resistor storage box 9, and one end of the guide plate 11 is fixedly connected to the bending seat 2. A rectangular groove is provided in the middle of the guide plate 11 to avoid the rotation of the feeding tray 12.

[0026] The working principle of the above scheme is as follows: Before use, several sets of parallel resistors 10 are placed in the resistor storage box 9. The drive motor 24 is started to drive the feeding tray 12 to rotate intermittently between the two sets of rotating supports 3. In the initial state, there are no resistors 10 in the bending seat 2. The bending cylinder 5 first pushes the support plate 25 to drive the bending pusher assembly 6 to descend and complete the preparatory action in one pneumatic pressurization. The resistors 10 in the resistor storage box 9 are guided by the guide plate 11 (the rectangular groove in the middle of the guide plate 11 avoids the rotation of the feeding tray 12) and are inserted one by one into the resistor slots 13 of the feeding tray 12. The rotation of the feeding tray 12 accurately delivers the resistors 10 to the bending seat 2. Then the bending cylinder 5 pushes the bending pusher assembly 6 to descend again to perform bending operations on the leads of the resistors 10 placed on the bending seat 2. Among them, the L-shaped bracket 4 realizes the stable installation of the bending cylinder 5, and the fixing column 7 realizes the reliable connection between the resistor storage box 9 and the mounting base 1, ensuring the overall structural stability.

[0027] The beneficial effects of the above scheme are as follows: 1. It constructs the basic core architecture of the device, and achieves orderly conveying of resistors through the cooperation of "feeding tray + guide plate", avoiding deviation during the conveying process and ensuring the accuracy of feeding; 2. The bending cylinder provides a stable bending driving force, which, together with the bending pusher assembly, achieves effective bending of the pins. The overall structure is simple and compact, easy to install, and the core components are reliably connected, making it suitable for mass production assembly; 3. The feeding tray adopts an intermittent rotation design, which forms a basic synergy with the action of the bending cylinder, reserving structural space for the subsequent expansion of linkage functions; 4. The design of the rectangular groove in the middle of the guide plate cleverly avoids the rotation trajectory of the feeding tray, avoids component interference, and improves the smoothness of device operation.

[0028] Example 2: Based on Example 1, please refer to... Figures 1-3The bending seat 2 is symmetrically provided with receiving seats 54 for placing the pins of resistor 10, and the center of the receiving seat 54 is provided with a bending groove 17. The surface of the receiving seat 54 is provided with a first guide slope 14 and a second guide slope 15. The bending seat 2 is provided with a guide groove 19, and the guide groove 19 extends all the way to the first guide slope 14. The receiving seat 54 is provided with several sets of air holes 18, and the air holes 18 extend all the way to the second guide slope 15. A clearance groove 16 is left between the two sets of receiving seats 54.

[0029] Preferably, the support plate 20 is movably disposed in the guide groove 19, and the bottom of the support plate 20 is connected to the bottom of the inner wall of the guide groove 19 through the return spring 22. One end of the telescopic airbag 21 is fixedly connected to the support plate 20, and the other end of the telescopic airbag 21 is fixedly connected to the inner wall of the guide groove 19. The telescopic airbag 21 is connected to each group of air holes 18 one by one through several sets of connecting air pipes 23.

[0030] The working principle of the above scheme is as follows: Based on embodiment 1, after the resistor 10 is fed to the bending seat 2 via the feeding tray 12, its two end leads will automatically roll along the guide slope 14 and guide slope 15 of the receiving seat 54 to the bending groove 17 in the center of the receiving seat 54, completing the pre-positioning of the leads; when the bending cylinder 5 drives the bending push head assembly 6 to descend, the positioning rod at the bottom of the drive box 26 will first insert into the guide groove 19 of the bending seat 2, and push the support plate 20 to slide downward along the guide groove 19, and the support plate 20 stretches the reset spring. Spring 22 simultaneously extends the telescopic airbag 21. The telescopic airbag 21 supplies air to the air hole 18 in the receiving seat 54 through several sets of connecting air pipes 23. The air hole 18 generates negative pressure to continuously attract the pins of resistor 10, preventing the pins from shifting during bending. After bending, the bending push head assembly 6 rises and resets. The reset spring 22 pushes the support plate 20 upward and resets it, squeezing the telescopic airbag 21. The telescopic airbag 21 blows air into the air hole 18 through the connecting air pipes 23. The airflow blows the pins away from the bending groove 17, preventing the pins from getting stuck.

[0031] The beneficial effects of the above solution are as follows: 1. The guide slope design of the receiving seat realizes automatic guidance and positioning of the pins, eliminating the need for an additional positioning mechanism and improving the efficiency of loading and positioning; 2. The negative pressure adsorption structure of "telescopic airbag + air hole" achieves stable fixation of the pins during bending, solving the problem of poor bending accuracy caused by easy displacement of the pins during traditional bending, and significantly improving bending quality; 3. The air blowing design during reset can quickly detach the bent pins from the bending groove, avoiding jamming between the pins and the bending groove due to excessive friction, ensuring smooth subsequent material handling and improving overall work efficiency; 4. The reset spring provides stable reset power to the support plate, ensuring reliable cycle realization of adsorption and air blowing functions, with strong structural linkage and low failure rate.

[0032] Example 3: Based on any one of Examples 1-2, please refer to... Figures 1-4 The bending pusher assembly 6 includes a drive housing 26, which is fixedly connected to a support plate 25. A drive motor 27 and a bidirectional threaded rod 29 are installed inside the drive housing 26. One end of the bidirectional threaded rod 29 is fixedly connected to the output shaft of the drive motor 27, and the other end of the bidirectional threaded rod 29 is rotatably connected to the inner wall of the drive housing 26. Two sets of pressure rods 28 are symmetrically sleeved on the outer wall of the bidirectional threaded rod 29, and the pressure rods 28 are threadedly connected to the bidirectional threaded rods 29. Two sets of sliding guide grooves for sliding of the pressure rods 28 are opened at the bottom of the drive housing 26. The resistor cover 30 is installed at the center of the bottom of the drive housing 26 through two sets of symmetrically arranged reset springs 31.

[0033] The working principle of the above scheme is as follows: Based on embodiments 1-2, for resistors 10 of different sizes, the bending pusher assembly 6 can be adjusted to meet the requirements: start the drive motor 27 to drive the bidirectional threaded rod 29 to rotate forward or reverse. Since the two sets of pressure rods 28 are threadedly connected to the bidirectional threaded rod 29 and are constrained by the guide groove at the bottom of the drive housing 26, the two sets of pressure rods 28 will slide synchronously along the guide groove in the direction of approaching or moving away from each other until the distance between the two sets of pressure rods 28 matches the distance between the two sets of bending grooves 17 of the receiving seat 54. During the bending operation, the resistor cover 30 at the bottom of the drive housing 26 will first contact the center of the resistor 10 body. The buffer effect of the reset spring 31 will protect the resistor 10 body. Then, the two sets of pressure rods 28 are precisely inserted into the bending grooves 17 to complete the bending operation of the resistor 10 pins.

[0034] The beneficial effects of the above solution are as follows: 1. It realizes the adjustable spacing function of the bending pusher. Through the cooperation of the bidirectional threaded rod and the pressure rod, it can accurately adapt to resistors with different pin spacings, greatly improving the versatility and adaptability of the device and reducing the equipment replacement cost when producing products of different specifications; 2. The design of the resistor cover can effectively protect the resistor body and avoid collision damage between the pressure rod or drive box and the resistor body during the bending process, reducing the product scrap rate; 3. The second reset spring provides a buffer for the resistor cover and can adapt to resistor bodies of different thicknesses, further improving the reliability of protection; 4. The adjustment process is driven by the second drive motor, which is precise and convenient to operate, eliminating the need for manual adjustment and improving the degree of production automation.

[0035] Example 4: Based on any one of Examples 1-3, please refer to Figures 1-5 The mounting base 1 has a baffle 41 rotatably provided on one side near the guide plate 11, and a through groove 43 for avoiding the arc-shaped push plate 49 is provided on the other side of the mounting base 1.

[0036] Preferably, a rotating support 35 is fixedly provided on the outer wall of the resistor storage box 9, and a drive rod 36 is rotatably connected to the rotating support 35. A gear 37 and a rope wheel 38 are fixedly provided at both ends of the drive rod 36, and a rack 34 is fixedly connected to the support plate 25. The rack 34 meshes with the gear 37.

[0037] Preferably, the outer wall of the resistor storage box 9 is fixedly provided with a limiting rope seat 39, a limiting rope seat 40, and a limiting rope seat 52, and the limiting rope seat 39 and the limiting rope seat 40 are located on the same horizontal line on the same side. One end of the connecting rope 53 is wrapped around the outer wall of the rope wheel 51, and the other end of the connecting rope 53 passes through the limiting rope seat 32, the limiting rope seat 40, and the limiting rope seat 39 in sequence and is wrapped around the rope wheel 38.

[0038] The working principle of the above scheme is as follows: Based on embodiments 1-3, the bending and feeding are linked: When the bending cylinder 5 drives the support plate 25 to rise and reset, the rack 34 fixed to the support plate 25 rises synchronously. The rack 34 meshes with the gear 37 to drive the gear 37 to rotate. The gear 37 drives the drive rod 36 to rotate on the rotating support 35, which in turn drives the rope wheel 38 to rotate and wind up the connecting rope 53. The connecting rope 53 is guided by the limiting rope seat 39, the limiting rope seat 40, and the limiting rope seat 52. After turning, the second rope wheel 51 rotates, and through the subsequent linkage structure, the arc-shaped push plate 49 passes through the through slot 43 of the mounting base 1 and enters the resistor storage box 9. It pushes the bottom resistor 10 to push open the baffle 41, slides along the track of the guide plate 11 and is locked into the resistor slot 13 of the feeding tray 12, completing one linkage feeding. When the bending cylinder 5 drives the second support plate 25 to descend, the rack 34 descends synchronously and drives the gear 37 to rotate in the opposite direction. The first rope wheel 38 releases the connecting rope 53, and the linkage structure resets to wait for the next feeding.

[0039] The beneficial effects of the above scheme are as follows: 1. By using the linkage structure of "rack-gear-pulley-rope", the reset power of the bending cylinder is converted into feeding power, eliminating the need for an additional feeding drive mechanism, simplifying the device structure, and reducing energy consumption and equipment costs; 2. The linkage feeding and bending actions are precisely synchronized, avoiding misalignment between feeding and bending actions when driven independently, thus improving the overall continuity and efficiency of the operation; 3. The setting of the limit rope seat enables precise guidance of the connecting rope, avoiding rope tangling and deviation, and ensuring the reliability of the linkage transmission; 4. The track on the guide plate further restricts the sliding trajectory of the resistor, and together with the blocking effect of the baffle, ensures that the resistor accurately enters the feeding tray slot, improving feeding stability.

[0040] Example 5: Based on any one of Examples 1-4, please refer to Figures 1-6The linkage component 8 includes a limiting head 44 and a rotating support 47. Both the limiting head 44 and the rotating support 47 are fixedly connected to the outer wall of the resistor storage box 9. The unblocking rod 45 is slidably connected to the limiting head 44. The driving rod 50 is rotatably connected to the rotating support 47. One end of the driving rod 50 is fixedly provided with a one-way threaded rod 46, and the other end of the driving rod 50 is fixedly provided with a rope wheel 51. The unblocking rod 45 is sleeved on the outer wall of the one-way threaded rod 46, and the one-way threaded rod 46 is... The unblocking rod 45 is threaded. The resistor storage box 9 has a through hole 42, and the through hole 42 and the unblocking rod 45 are on the same axis. The arc-shaped push plate 49 is fixedly sleeved on the outer wall of the drive rod 2 50, and the movement trajectory of the arc-shaped push plate 49 corresponds to the through groove 43. It can pass through the through groove 43 to avoid collision. The torsion spring 48 is sleeved on the outer wall of the drive rod 2 50, and one end of the torsion spring 48 is fixedly connected to the rotating support 3 47, and the other end of the torsion spring 48 is fixedly connected to the outer wall of the drive rod 2 50.

[0041] Preferably, the guide plate 11 is provided with a track for limiting the resistor 10 to prevent the resistor 10 from deviating.

[0042] The working principle of the above scheme is as follows: Based on embodiments 1-4, the linkage component 8 realizes the dual functions of feeding linkage and storage box unblocking: When the first rope wheel 38 in embodiment 4 winds up the connecting rope 53, it drives the second rope wheel 51 to rotate. The second rope wheel 51 drives the second drive rod 50 to rotate on the rotating support 47. The second drive rod 50 drives the arc-shaped push plate 49 through the through groove 43 to push the resistor 10 to feed the material. At the same time, the torsion spring 48 is twisted to accumulate kinetic energy. When the bending push head assembly 6 rises and resets, and the rack 34 drives the gear 37 to rotate in the opposite direction, the first rope wheel 38 releases the connecting rope 53, and the torsion spring 48 is twisted to accumulate kinetic energy. Spring 48 releases potential energy to drive drive rod 50 to reverse and reset. Arc-shaped push plate 49 disengages from resistor storage box 9 through through slot 43, and resistor 10 inside the box drops one level. When drive rod 50 reverses, it simultaneously drives one-way threaded rod 46 to rotate. Since unblocking rod 45 is threadedly connected to one-way threaded rod 46 and constrained by limit head 44, unblocking rod 45 slides upward along limit head 44 and inserts into storage box through through hole 42 to sort out the state of resistor 10 inside the box, ensuring that it smoothly enters the bottom of the vertical section of storage box and avoids blockage. The track of guide plate 11 synchronously restricts the sliding trajectory of resistor 10 to prevent deviation.

[0043] The beneficial effects of the above solution are as follows: 1. It realizes the integrated function of "feeding linkage - reset - unblocking". The dynamic potential energy of the torsion spring realizes the automatic reset of the linkage component, eliminating the need for an additional reset drive, further simplifying the structure and reducing energy consumption; 2. The design of the unblocking rod effectively solves the problem of resistor stacking and blockage in the resistor storage box, ensuring continuous and smooth resistor feeding, avoiding production interruptions caused by blockage, and improving the stability of equipment operation; 3. The cooperation between the one-way threaded rod and the unblocking rod converts the rotation of the drive rod into the linear sliding of the unblocking rod, making the unblocking action precise and controllable, and preventing excessive compression damage to the resistor; 4. The motion trajectory of the arc-shaped push plate is precisely matched with the through groove, avoiding component interference. The torsion spring provides stable reset power, ensuring reliable cyclic operation of the linkage component; 5. The guide plate track further ensures the accuracy of the resistor conveying trajectory, improving the overall stability and accuracy of the operation.

[0044] Furthermore, when using the present invention as described in Examples 1-5, several sets of resistors 10 need to be placed into the resistor storage box 9 in advance (several sets of resistors 10 need to be placed in parallel). By starting the drive motor 24, the feeding tray 12 can be rotated intermittently. At the same time, the bending cylinder 5 pushes the support plate 25 to drive the bending pusher assembly 6 to lower the air pressure once (when using it for the first time, there are no resistors 10 placed on the bending seat 2, so the bending pusher assembly 6 needs to be air-pressed once). Subsequently, when the bending cylinder 5 drives the bending pusher assembly 6 to reset through the support plate 25, the rack 34 pushes the gear 37 to drive the drive rod 36 to rotate, thereby causing the rope wheel 38 to wind up the connecting rope 53. When the connecting rope 53 is wound up, it passes through the limiting rope seat 39, the limiting rope seat 40, and the limiting rope seat 52, thereby driving the rope wheel 51 to rotate (connecting rope 5 3. In the initial stage, the resistor is wound around the second rope wheel 51. The second rope wheel 51 drives the arc-shaped push plate 49 to rotate through the second drive rod 50 (the torsion spring 48 accumulates kinetic energy at this time) until the arc-shaped push plate 49 passes through the through groove 43 and enters the resistor storage box 9, and gives a push force to the resistor 10 located at the bottom of the resistor storage box 9, so that it can push the baffle 41 open and slide along the guide plate 11 (the guide plate 11 is provided with a track for limiting the resistor 10 to prevent the resistor 10 from deviating) until the resistor 10 is just inserted into the resistor slot 13 of the feeding tray 12, and is transported to the guide slope 14 of the receiving seat 54 by the rotation of the feeding tray 12. At this time, the pins at both ends of the resistor 10 will roll along the guide slope 14 and the guide slope 2 15 on both sides to the V-shaped groove of the receiving seat 54, thus completing one feeding of the resistor 10.

[0045] At this time, the bending cylinder 5 drives the bending pusher assembly 6 to descend. Several sets of positioning rods 32 at the bottom of the drive housing 26 will first insert into the guide groove 19 and push the support plate 20 to descend. The support plate 20 will pull the telescopic airbag 21 to extend, thereby evacuating the air holes 18 through several sets of connecting air pipes 23. At this time, the several sets of air holes 18 can continuously attract the pins of the resistor 10 to prevent them from changing position during bending, until the resistor cover 30 moves to the bottom of the relief groove 16 and protects the center of the resistor 10 through the arc-shaped relief groove 33. At the same time, the two sets of pressure rods 28 While being inserted into the bending groove 17, the leads of the resistor 10 can be bent. After one bending operation is completed, the bending pusher assembly 6 rises and resets. The reset spring 22 pushes the support plate 20 upward and resets it. While the telescopic airbag 21 is compressed, air is blown into the air holes 18 through the connecting air pipe 23. At this time, several sets of air holes 18 can continuously blow on the leads of the resistor 10, thereby causing the leads of the resistor 10 to disengage from the bending groove 17 and prevent jamming. At this time, any robotic arm can be used to pick up the resistor 10 from the receiving seat 54 and move it to the next process.

[0046] It should be noted that when the rack 34 rises, it drives the gear 37 to rotate in the opposite direction, thereby releasing the connecting rope 53 wound on the first rope wheel 38. At this time, the torsion spring 48 releases the accumulated kinetic energy, causing the second drive rod 50 to flip and reset. At this time, the arc-shaped push plate 49 disengages from the resistor storage box 9 through the through slot 43, and the resistor 10 will drop one position. At the same time, the second drive rod 50 reverses and drives the one-way threaded rod 46 to rotate. The unblocking rod 45 slides upward along the limiting head 44 and is inserted into the resistor storage box 9 through the through hole 42. This allows the state of several sets of resistors 10 in the resistor storage box 9 to be adjusted, so that the resistors 10 can smoothly enter the bottom of the vertical section of the resistor storage box 9 and prevent blockage.

[0047] The bending seat 2 is bolted to the mounting base 1. For resistors 10 of different sizes, the receiving seat 54 of different sizes needs to be replaced in advance. After the new bending seat 2 is installed, the drive motor 27 is started to drive the bidirectional threaded rod 29 to rotate in both directions, thereby causing the two sets of pressure rods 28 to move in the direction of moving away from each other and towards each other, until the distance between the two sets of pressure rods 28 matches the distance between the two sets of bending grooves 17, so as to be able to adapt to resistors 10 of different sizes.
