Description

Technical Field

[0001] This invention relates to the field of electromagnetic component manufacturing equipment technology, specifically to a bending and paint-removing device for electromagnetic coils and its usage method. Background Technology

[0002] Electromagnetic coils, as the core component for converting electrical energy into magnetic energy, are widely used in relays, sensors, motors, and various inductive devices. The final stage of their manufacturing process typically requires two key processing steps on the coil leads: first, precisely bending the straight leads into specific shapes (such as 90° or acute angles) to meet the requirements for mounting on circuit boards or connecting with other wires; second, stripping the varnish from the bent leads to remove the surface insulating varnish layer, ensuring electrical conductivity for subsequent soldering or connections.

[0003] Currently, most manufacturers use a step-by-step processing method to manufacture the leads of electromagnetic coils. In this process, operators first use specialized bending fixtures or semi-automatic bending machines to shape the leads. After bending, the workpiece is transferred to a separate paint removal station for further processing, including mechanical scraping, chemical immersion, or laser burning.

[0004] However, this decentralized production model of "bending-transfer-removal" has significant problems. Frequent clamping and transfer lead to production interruptions, low overall efficiency, and are not easily adapted to modern automated production lines. At the same time, the heavy reliance on manual operation increases labor costs and exposes operators to safety hazards from exposure to chemical paint removers or laser equipment. Summary of the Invention

[0005] The purpose of this application is to provide a bending and paint removal device for electromagnetic coils and a method for using the device, which can automatically bend and remove paint from the leads, improve production efficiency and automation, reduce labor costs, and enhance production safety.

[0006] This invention provides a bending and paint stripping device for electromagnetic coils. The technical solution is as follows: A bending and paint stripping device for electromagnetic coils includes a machine body and a feeding mechanism, a bending module, a paint stripping module, a unloading mechanism, a first transfer mechanism, and a second transfer mechanism mounted on the machine body. The feeding mechanism is used to transport the electromagnetic coil to a first preset position. The bending module is used to bend the leads of the electromagnetic coil, including a bending fixing frame fixed on the machine body, a positioning mechanism on the bending fixing frame for positioning the electromagnetic coil, and a bending mechanism on the bending fixing frame for bending the leads of the electromagnetic coil. The bending mechanism includes a lifting frame that can be raised and lowered on the bending fixing frame, a rotating seat rotatably mounted on the lifting frame, a central column at the center of the rotating seat, and a bending mechanism on the rotating seat located on one side of the central column for inserting the lead into the gap between the lead and the electromagnetic coil. The system includes a bending block and a bending motor for driving the rotating seat to rotate so that the bending block cooperates with the central column to bend the leads; the paint stripping module is used to strip the paint from the leads of the bent electromagnetic coil, including a paint stripping conveyor line, a carrier on the paint stripping conveyor line for carrying the electromagnetic coil, and two sets of paint stripping mechanisms symmetrically arranged on both sides of the paint stripping conveyor line for stripping the leads of the electromagnetic coil. After the paint stripping is completed, the paint stripping conveyor line is used to transport the electromagnetic coil to a second preset position; the unloading mechanism is used to unload the electromagnetic coil after the paint stripping is completed; the first transfer mechanism is used to transfer the electromagnetic coil transported to the first preset position by the loading mechanism to the bending module, so that the bending mechanism bends its leads, and then transfers the electromagnetic coil after the leads are bent to the paint stripping module; the second transfer mechanism is used to transfer the electromagnetic coil at the second preset position to the unloading mechanism to achieve the final unloading.

[0007] This application also provides a method of using a bending and paint stripping device for electromagnetic coils, applicable to the bending and paint stripping device for electromagnetic coils as described above, comprising the following steps:

[0008] The electromagnetic coil is conveyed to the first preset position by the feeding mechanism, and the electromagnetic coil at the first preset position is transferred to the bending mechanism by the first transfer mechanism.

[0009] The electromagnetic coil is positioned by a positioning mechanism, and then the pins of the electromagnetic coil are bent by a bending mechanism.

[0010] The bent leads are trimmed by a lead trimming mechanism, and the waste generated during the trimming process is collected by a waste collection mechanism.

[0011] The electromagnetic coil is transferred to the coil adjustment mechanism by the first transfer mechanism. The position of the electromagnetic coil is adjusted by the coil adjustment mechanism, and the adjusted electromagnetic coil is placed on the carrier on the paint stripping conveyor line, ensuring that the pin is located at the upper position of the electromagnetic coil.

[0012] The carrier is transported to the pin adjustment mechanism via the paint stripping conveyor line. The pin adjustment mechanism adjusts the perpendicularity of the pin to keep the pin perpendicular to the end plane of the electromagnetic coil.

[0013] The carrier is transported to the laser paint stripping mechanism via a paint stripping conveyor line, where the paint stripping mechanism removes the paint from the pins.

[0014] The carrier is transported to the second preset position by the paint stripping conveyor line, and the second transfer mechanism transfers the electromagnetic coil on the carrier to the unloading mechanism to achieve the final unloading.

[0015] After adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0016] This application provides a bending and paint stripping device for electromagnetic coils and its usage method. The device, by configuring a feeding mechanism, a bending module, a paint stripping module, a unloading module, a first transfer mechanism, and a second transfer mechanism, realizes the automatic feeding, bending, paint stripping, and unloading process of electromagnetic coils. This effectively reduces reliance on manual labor, significantly improves production efficiency and automation level, while also reducing production costs and safety hazards, and has promising market prospects.

Figures 1-20 The technical solutions in the embodiments of the present invention are clearly and completely described herein.

Furthermore, the technical solutions 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.

[0050] This embodiment provides a bending and paint stripping device for electromagnetic coils, which is used to bend and strip paint from the leads 210 of an electromagnetic coil 200, such as... Figure 1 and Figure 2 As shown, it displays two electromagnetic coils 200, in which... Figure 1 The electromagnetic coil 200 shown is the one that has not undergone bending or paint removal treatment. Figure 2 The electromagnetic coil 200 after being processed by the bending and paint removal equipment 100 provided in this application has the following characteristics: the lead 210 of the electromagnetic coil 200 before bending and paint removal is parallel to the end plane of the electromagnetic coil 200 and extends outward in a direction parallel to the end plane; while the lead 210 of the electromagnetic coil 200 after being processed by the bending and paint removal equipment 100 is perpendicular to the end plane of the electromagnetic coil 200 and extends outward in a direction perpendicular to the end plane.

[0051] Reference Figure 3The bending and paint stripping equipment 100 provided in this application includes a machine body 110 and a feeding mechanism 10, a bending module 20, a paint stripping module 30, a unloading mechanism 40, a first transfer mechanism 50, a second transfer mechanism 60, and a control mechanism disposed on the machine body 110. The feeding mechanism 10 is used to transport the electromagnetic coil 200 to a first preset position 120; the bending module 20 is used to bend the leads 210 of the electromagnetic coil 200; the paint stripping module 30 is used to strip the paint from the leads 210 of the bent electromagnetic coil 200 and transport the stripped electromagnetic coil 200 to a second preset position 130; the unloading module is used to unload the stripped electromagnetic coil 200; and the first transfer mechanism 50 is used to transport the coil from the feeding mechanism 10 to the first preset position 120. The electromagnetic coil 200 at the preset position 120 is transferred to the bending module 20, which bends its pins 210. The electromagnetic coil 200 with the pins 210 bent is then transferred to the paint stripping module 30. The second transfer mechanism 60 is used to transfer the electromagnetic coil 200 at the second preset position 130 to the unloading mechanism 40 to achieve final unloading. The control mechanism is electrically connected to the loading mechanism 10, bending module 20, paint stripping module 30, unloading mechanism 40, first transfer mechanism 50 and second transfer mechanism 60 to control the loading mechanism 10, bending module 20, paint stripping module 30, unloading mechanism 40, first transfer mechanism 50 and second transfer mechanism 60 to work together to achieve automatic loading, bending, paint stripping and unloading of the electromagnetic coil 200.

[0052] During operation, the electromagnetic coil 200 is first transported to the first preset position 120 by the feeding mechanism 10. The first transfer mechanism 50 then transfers the electromagnetic coil 200 from the first preset position 120 to the bending module 20 for lead 210 bending. The bending module 20 precisely bends the leads 210 of the electromagnetic coil 200 according to preset bending parameters, ensuring that the shape of the leads 210 meets the subsequent assembly requirements. After the lead 210 bending is completed, the first transfer mechanism 50 transfers the bent electromagnetic coil 200 to the paint stripping module 30. The paint stripping module 30 strips the paint from the bent leads 210. After the paint stripping is completed, the electromagnetic coil 200 is transported to the second preset position 130. At this time, the second transfer mechanism 60 smoothly transfers the electromagnetic coil 200 from the second preset position 130 to the unloading mechanism 40. The unloading mechanism 40 unloads the paint-stripped electromagnetic coil 200 for subsequent manual handling or automatic assembly. Throughout the process, the control mechanism coordinates the feeding mechanism 10, bending module 20, paint stripping module 30, unloading mechanism 40, first transfer mechanism 50, and second transfer mechanism 60 to ensure the efficiency, stability, and reliability of the entire bending and paint stripping process.

[0053] Furthermore, referring to Figure 4The feeding mechanism 10 includes a feeding conveyor line 11 on the machine body 110 and a plurality of carrier plates 12 evenly arranged on the feeding conveyor line 11. One end of the feeding conveyor line 11 is the feeding end 111, and the other end is the discharging end 112. The first preset position 120 is located on the side of the feeding conveyor line 11 near the material picking end. The carrier plate 12 is provided with a plurality of placement slots 121 for placing electromagnetic coils 200. In the specific implementation process, the electromagnetic coils 200 can be placed in the placement slots 121 of the carrier plate 12 by manual labor or a robot at the feeding end 111 to realize the feeding of electromagnetic coils 200.

[0054] In addition, the feeding mechanism 10 also includes a feeding sensing component 13, which is located at the first preset position 120 and is used to sense the electromagnetic coil 200. The feeding sensing component 13 includes a feeding sensing bracket 131 and a feeding sensing sensor mounted on the feeding sensing bracket 131. The feeding sensing sensor is electrically connected to the control mechanism. When the feeding conveyor line 11 transports the electromagnetic coil 200 to the first preset position 120, the feeding sensor 132 senses the presence of material and sends a signal to the control mechanism. The control mechanism then controls the feeding conveyor line 11 to stop transporting, causing the electromagnetic coil 200 to remain at the first preset position 120, waiting to be transferred by the first transfer mechanism 50 to the bending module 20 for bending. If the feeding sensor 132 senses no material, the control mechanism continues to control the feeding conveyor line 11 to transport material until the next electromagnetic coil 200 is transported to the first preset position 120.

[0055] Furthermore, referring to Figure 1 and Figure 5 The bending module 20 includes a bending fixing frame 21 fixed on the body 110, a positioning mechanism 22 on the bending fixing frame 21 for positioning the electromagnetic coil 200, and a bending mechanism 23 on the bending fixing frame 21 for bending the pins 210 of the electromagnetic coil 200.

[0056] The positioning mechanism 22 is used to accurately position the electromagnetic coil 200 to ensure that the electromagnetic coil 200 remains fixed during the bending process, preventing it from moving or shifting, which would affect the accuracy and quality of the bending.

[0057] Specifically, refer to Figure 5 , Figure 6 and Figure 7 The positioning mechanism 22 includes two positioning seats 221 fixed on the bending fixing frame 21, a first positioning component slidably disposed on the bending fixing frame 21 for positioning the electromagnetic coil 200 from a first direction, and a second positioning component for positioning the electromagnetic coil 200 from a second direction. The two positioning seats 221 cooperate to form a positioning groove for positioning the electromagnetic coil 200. The positioning groove has an opening facing the first positioning component.

[0058] The first positioning component includes a first sliding plate 222 slidably disposed on the bending fixing frame 21 and a first positioning drive cylinder for driving the first sliding plate 222 to move in a first direction toward or away from the positioning seat 221 so as to press the electromagnetic coil 200 against the side wall of the two positioning seats 221. The first sliding plate 222 is provided with a first abutting part 224 corresponding to the position of the electromagnetic coil 200 to abut against the electromagnetic coil 200.

[0059] The second positioning assembly includes a second sliding plate 225 slidably disposed on the top of the bending fixing frame 21, a lifting plate 226 disposed vertically on the bottom side of the second sliding plate 225 along a second direction, a second positioning drive cylinder 227 for driving the second sliding plate 225 to move directly above the positioning seat 221, and a positioning lifting cylinder 228 for driving the lifting plate 226 to rise and fall vertically relative to the second sliding plate 225 along the second direction. The bottom side of the lifting plate 226 is provided with a second abutting part 229 that abuts and cooperates with the electromagnetic coil 200.

[0060] During operation, the second positioning drive cylinder 227 first drives the second sliding plate 225 to move, moving it from directly above the positioning seat 221 to slightly above it, making way for the first transfer mechanism 50. This allows the first transfer mechanism 50 to smoothly transfer the electromagnetic coil 200 into the positioning groove formed by the two positioning seats 221. At this time, the first positioning drive cylinder drives the first sliding plate 222 to move along the first direction toward the positioning seat 221, causing the first abutting part 224 of the first sliding plate 222 to press against the side wall of the electromagnetic coil 200, thereby achieving positioning of the electromagnetic coil 200 in the first direction. Simultaneously, the second sliding plate 225 is moved by the second positioning cylinder to the position directly above the positioning seat 221. Then, the lifting plate 226 is driven to descend vertically in the second direction by the positioning lifting cylinder 228, so that the second abutting part 229 on the bottom side of the lifting plate 226 abuts against the top of the electromagnetic coil 200, thereby achieving the positioning of the electromagnetic coil 200 in the second direction, ensuring the stability of the electromagnetic coil 200, and ensuring bending accuracy.

[0061] Furthermore, referring to Figure 6 , Figure 8 , Figure 9 and Figure 10The bending mechanism 23 includes a lifting frame 231 that can be lifted and lowered on the bending fixing frame 21, a rotating seat 232 that is rotatably mounted on the lifting frame 231, a central column 233 located at the center of the rotating seat 232, a bending block 234 located on the rotating seat 232 on one side of the central column 233 and used to insert the pin 210 into the gap between the electromagnetic coil 200, and a bending motor 235 for driving the rotating seat 232 to rotate so that the bending block 234 cooperates with the central column 233 to bend the pin 210. The bending fixing frame 21 is provided with a bending lifting cylinder 236 for driving the lifting frame 231 to rise and fall vertically relative to the bending fixing frame 21.

[0062] After the electromagnetic coil 200 is positioned in the first and second directions by the first and second positioning components respectively, the bending lifting cylinder 236 drives the lifting seat to rise, so that the rotating block on the rotating seat 232 is inserted into the gap between the electromagnetic coil 200 and the pin 210. At the same time, the central column 233 is located on the side of the pin 210 away from the electromagnetic coil 200. At this time, the bending motor 235 drives the rotating seat 232 to rotate, which drives the central column 233 and the bending block 234 to rotate, so that the bending block 234 and the central column 233 cooperate to bend the pin 210. After the bending is completed, the bending lifting cylinder 236 drives the lifting seat to fall again, so that the rotating seat 232 and its components are reset, so as to perform the next bending operation.

[0063] In addition, refer to Figure 8 In this embodiment, to improve bending accuracy, a connecting shaft 237 is connected between the output shaft of the bending motor 235 and the rotating seat 232. A sensing ring with a notch is provided on the connecting shaft 237. The arc length of the notch corresponds to the preset bending angle of the pin 210. A bending sensor 239 is provided on the lifting frame 231 at the position corresponding to the sensing ring. The bending sensor 239 is electrically connected to the control mechanism. Initially, the starting end of the notch in the sensing ring is located within the sensing area of ​​the bending sensor 239. When the bending motor 235 drives the rotating seat 232 to rotate so that the bending block 234 cooperates with the center column 233 to bend the pin 210, the connecting shaft 237 rotates, causing the sensing ring to rotate. When the ending end of the notch in the sensing ring rotates into the sensing area of ​​the bending sensor 239, the bending sensor 239 senses the sensing ring again. Then, the bending sensor 239 sends a signal to the control mechanism, and the control mechanism controls the bending motor 235 to stop rotating, thereby achieving precise control of the bending angle of the pin 210.

[0064] Furthermore, referring to Figure 5 and Figure 6 The bending module 20 also includes a pin trimming mechanism 24 for trimming the bent pins 210 and a waste collection mechanism 25 for collecting the waste generated during the trimming of the pins 210.

[0065] The lead trimming mechanism 24 trims the bent leads 210 to keep the lead lengths consistent, thereby improving the quality of the finished product and preventing inconsistent lead lengths. The waste collection mechanism 25 collects the waste generated during the cutting process, keeping the working environment clean and preventing waste accumulation from polluting the work area.

[0066] Furthermore, referring to Figure 5 , Figure 6 and Figure 11 The pin trimming mechanism 24 includes a fixed plate 241 fixedly disposed on one side of the bending fixing frame 21, a shearing assembly 242 slidably disposed on the fixed plate 241, and a trimming cylinder 243 for driving the shearing assembly 242 to move toward or away from the bending fixing frame 21. The shearing part 2421 of the shearing assembly 242 is flush with the bent pin 210, so that when the trimming cylinder 243 drives the shearing assembly 242 to move toward the bending fixing frame 21, the shearing part 2421 of the shearing assembly 242 can trim the bent pin 210.

[0067] In this embodiment, the shearing assembly 242 is a pneumatic shearing device, which includes a shearing part 2421 and a pneumatic drive structure for driving the shearing part 2421. In other embodiments, it may also be a hydraulic shearing device or other shearing device capable of shearing, which will not be elaborated here.

[0068] After bending is completed, the pin trimming mechanism 24 starts to work. The trimming cylinder 243 drives the shearing assembly 242 to move closer to the bending fixture 21, so that the shearing part 2421 of the shearing assembly 242 can trim the bent pin 210, so that the length of the pin 210 is consistent. After the trimming is completed, the trimming cylinder 243 drives the shearing assembly 242 to move away from the bending fixture 21, so as to prepare for the trimming of the next pin 210.

[0069] Furthermore, the waste collection mechanism 25 includes a waste fixing frame 251 fixedly mounted on the bending fixing frame 21, a waste guide tube 252 movably disposed between the waste fixing frame 251 and the pin trimming mechanism 24, a waste collection box 253 disposed on the waste fixing frame 251 for receiving waste falling from the waste guide tube 252, and a waste collection cylinder 254 for driving the waste guide tube 252 to move toward or away from the pin trimming mechanism 24.

[0070] Specifically, the waste fixing frame 251 is fixedly installed on one side of the bending mechanism 23, the cylinder body of the waste collection cylinder 254 is fixedly installed on the waste fixing frame 251, the waste guide cylinder 252 is inclined, its top end is used to extend into the pin 210 mechanism and receive the waste generated during shearing, and its bottom end is fixedly installed on the piston rod of the waste collection cylinder 254, and the waste collection box 253 is an open box.

[0071] After bending is completed, the lifting frame 231 first returns to its initial position to make way for the waste guide cylinder 252, allowing the waste collection cylinder to extend smoothly. The trimming cylinder 243 drives the shearing assembly 242 to move closer to the bending fixing frame 21, so that the bent pin 210 part enters the shearing opening of the shearing part 2421. Then, the waste collection cylinder 254 drives the waste guide cylinder 252 to extend into the shearing mechanism and be located below the pin 210. At this time, the top opening of the waste guide cylinder 252 faces the shearing part 2421 of the shearing assembly 242 to receive the waste generated by shearing. Then, the shearing assembly 242 works to trim the pin 210, and the waste generated by trimming falls into the waste guide cylinder 252, and then falls into the waste collection box 253, completing the trimming and waste collection work. Finally, the shearing assembly 242 and the waste collection assembly both return to their initial state, preparing for the next trimming and waste collection.

[0072] Furthermore, referring to Figure 3 and Figure 12 The paint stripping module 30 includes a paint stripping conveyor line 31 on the body 110, a carrier 32 on the paint stripping conveyor line 31 for carrying the electromagnetic coil 200, and two sets of paint stripping mechanisms 33 symmetrically arranged on both sides of the paint stripping conveyor line 31 for stripping the paint from the pins 210 of the electromagnetic coil 200. After the paint stripping is completed, the paint stripping conveyor line 31 is used to transport the electromagnetic coil 200 to the second preset position 130.

[0073] When the carrier 32 carrying the electromagnetic coil 200 moves to the paint stripping mechanism 33 under the conveying of the paint stripping conveyor line 31, the paint stripping mechanism 33 strips the paint from the pins 210 of the electromagnetic coil 200. After the paint stripping is completed, the paint stripping conveyor line 31 continues to convey the carrier 32 and the electromagnetic coil 200 to the second preset position 130.

[0074] Furthermore, referring to Figure 12 and Figure 13The paint stripping mechanism 33 includes a paint stripping fixed plate 331 fixedly disposed on one side of the paint stripping conveyor line 31, a paint stripping sliding plate 332 slidably disposed on the paint stripping fixed plate 331, a paint stripping rotating frame 333 rotatably disposed on the paint stripping sliding plate 332, a laser paint stripping component 334 slidably disposed on the paint stripping rotating frame 333, a first paint stripping driving component for driving the paint stripping sliding plate 332 to move, and a second paint stripping driving component for driving the laser paint stripping component 334 to move. The laser emitting end of the laser paint stripping component 334 faces the paint stripping conveyor line 31.

[0075] The first paint stripping drive assembly is used to drive the paint stripping sliding plate 332 to slide along the length direction of the paint stripping conveyor line 31 to adjust the position of the laser paint stripping assembly 334 relative to the paint stripping conveyor line 31. The second paint stripping drive assembly is used to drive the laser paint stripping assembly 334 to move towards or away from the paint stripping conveyor line 31 to adjust the distance between the laser paint stripping assembly 334 and the paint stripping conveyor line 31.

[0076] In some specific embodiments, refer to Figure 14 The paint stripping sliding plate 332 is slidably connected to the paint stripping fixed plate 331 via a slide rail 3311 and a slider 3312. The first paint stripping drive assembly includes a paint stripping drive cylinder fixedly mounted on the paint stripping fixed plate 331. The paint stripping drive cylinder is arranged along the length direction of the paint stripping conveyor line 31, and the piston rod of the paint stripping drive cylinder is fixedly connected to one side of the paint stripping sliding plate 332. By driving the paint stripping sliding plate 332 to move along the length direction of the paint stripping conveyor line 31 through the paint stripping drive cylinder, the position of the laser paint stripping assembly 334 relative to the paint stripping conveyor line 31 is adjusted, thereby realizing the adjustment of the paint stripping position.

[0077] In some specific embodiments, the laser paint stripping component 334 is slidably connected to the paint stripping rotating frame 333 via a groove and sliding block structure. The second paint stripping drive component includes a guide rod 336, a threaded rod 337, and a handwheel 338. By rotating the handwheel 338, the threaded rod 337 is driven to rotate, thereby causing the laser paint stripping component 334 to slide relative to the paint stripping rotating frame 333. That is, the laser paint stripping component 334 moves relative to the paint stripping rotating frame 333 towards or away from the paint stripping conveyor line 31, thereby adjusting the distance between the laser paint stripping component 334 and the paint stripping conveyor line 31, and thus adjusting the laser intensity emitted from the laser emitting end of the laser paint stripping component 334. In other embodiments, the second paint stripping drive component may also adopt a cylinder drive or a screw motor drive structure, etc., which are not limited here.

[0078] Furthermore, in this embodiment, the paint stripping rotating frame 333 is rotatably connected to the paint stripping sliding plate 332 via an angle adjustment mechanism 339, which is used to adjust the laser emission angle of the laser paint stripping assembly 334. There are two sets of angle adjustment mechanisms 339, symmetrically arranged on both sides of the paint stripping rotating frame 333.

[0079] Specifically, the angle adjustment mechanism 339 includes a first adjustment seat 3391 fixedly mounted on the paint stripping sliding plate 332, an adjustment groove 3392 opened on the paint stripping rotating frame 333, an adjustment block 3393 slidably mounted on the adjustment groove 3392, a second adjustment seat 3394 fixedly mounted on the paint stripping sliding plate 332, and an adjustment screw 3395 for connecting the adjustment block 3393 and the second adjustment seat 3394. One end of the paint stripping rotating frame 333 near the paint stripping conveyor line 31 is rotatably connected to the first adjustment seat 3391 via a rotating shaft. The adjustment block 3393 is provided with a through hole for the adjustment screw 3395 to pass through. The second adjustment seat 3394 is provided with a corresponding screw hole. The bottom end of the adjustment screw 3395 passes through the through hole and is threaded into the screw hole, thereby realizing the connection between the adjustment block 3393 and the second adjustment seat 3394, and thus locking the rotation angle of the paint stripping rotating frame 333.

[0080] Furthermore, referring to Figure 12 and Figure 15 A coil adjustment mechanism 70 is provided between the bending module 20 and the paint removal module 30. The coil adjustment mechanism 70 is used to adjust the position of the pin 210 relative to the electromagnetic coil 200, so as to ensure that the pin 210 is located above the electromagnetic coil 200 so that the paint removal mechanism 33 can remove the paint from it.

[0081] It should be noted that in this embodiment, when the feeding mechanism 10 conveys the electromagnetic coil 200 to the first preset position 120, the pin 210 is located at the lower part of the electromagnetic coil 200. This is to facilitate the bending mechanism 23 to bend the pin 210. However, during paint removal, if the pin 210 is still located at the lower part of the electromagnetic coil 200, the paint removal mechanism 33 will have a poor paint removal effect on the pin 210. Therefore, this application adjusts the position of the pin 210 relative to the electromagnetic coil 200 by setting the coil adjustment mechanism 70 to ensure that the pin 210 is located at the upper part of the electromagnetic coil 200, thereby facilitating the paint removal mechanism 33 to remove the paint from the pin 210 and ensuring the paint removal effect.

[0082] Specifically, refer to Figure 15The coil adjustment mechanism 70 includes a coil adjustment fixing frame 71 located on one side of the paint stripping conveyor line 31, a coil adjustment lifting seat 72 that can be lifted and lowered on the coil adjustment fixing frame 71, a coil adjustment bearing seat 73 that is rotatably located on the coil adjustment lifting seat 72, a coil adjustment positioning plate 74 that is movably located on the coil adjustment bearing seat 73 for positioning the electromagnetic coil 200, a coil adjustment lifting cylinder 75 for driving the coil adjustment lifting seat 72 to rise and fall vertically, a coil adjustment flipping cylinder 76 (or a flipping motor) for driving the coil adjustment bearing seat 73 to flip, and a coil adjustment positioning plate 74 for driving the coil adjustment positioning plate 74 to move relative to the coil adjustment bearing seat 73. A coil adjustment cylinder 77 is used to fix the electromagnetic coil 200 on the coil adjustment support 73. The coil adjustment support 73 is provided with a receiving groove 731 for accommodating the electromagnetic coil 200. The coil adjustment support 73 is located directly above the paint stripping conveyor line 31 and can be rotated vertically under the drive of the coil adjustment flipping cylinder 76 to adjust the position of the pin 210 relative to the electromagnetic coil 200. The coil adjustment positioning plate 74 moves relative to the coil adjustment support 73 under the drive of the coil adjustment cylinder 77 to fix the electromagnetic coil 200 on the coil adjustment support 73, or to release the electromagnetic coil 200 so that it falls onto the carrier 32 on the paint stripping conveyor line 31.

[0083] During operation, the first transfer mechanism 50 places the bent electromagnetic coil 200 (with pin 210 bent) into the receiving groove 731 of the coil adjustment support 73. At this time, pin 210 is located at the lower part of the electromagnetic coil 200. The coil adjustment cylinder 77 drives the coil adjustment positioning plate 74 to move into the receiving groove 731, firmly clamping the electromagnetic coil 200 onto the coil adjustment support 73. Subsequently, the coil adjustment tilting cylinder 76 is activated, driving the coil adjustment support 73 to tilt 180° vertically, causing the electromagnetic coil 200 to tilt 180°, so that pin 210 is located at the upper part of the electromagnetic coil 200. Then, the coil adjustment lifting cylinder 75 is activated, causing the coil adjustment lifting seat 72 and the coil adjustment support 73 to descend together. The coil adjustment cylinder 77 drives the coil adjustment positioning plate 74 to move away from the receiving groove 731, so that the electromagnetic coil 200 falls steadily onto the carrier 32, which has been pre-moved directly below the coil adjustment support 73. Finally, the coil adjustment lifting cylinder 75 drives the coil adjustment lifting seat 72 to rise, and the coil adjustment flipping cylinder 76 drives the coil adjustment bearing seat 73 to reset, preparing for the next adjustment of the electromagnetic coil 200.

[0084] Furthermore, referring to Figure 12 , Figure 16 and Figure 17 A pin adjustment mechanism 80 is also provided between the coil adjustment mechanism 70 and the paint removal mechanism 33. The pin adjustment mechanism 80 is used to adjust the perpendicularity of the pin 210 relative to the end plane of the electromagnetic coil 200.

[0085] It should be noted that in the actual production process, the bending angle of the pin 210 will inevitably have a certain error, which will cause a large deviation between the pins 210 on the left and right sides of the electromagnetic coil 200, thus affecting the subsequent paint removal effect. Therefore, this application improves the paint removal effect of the pin 210 by setting a pin adjustment mechanism 80 to adjust the perpendicularity of the pin 210 relative to the end plane of the electromagnetic coil 200.

[0086] Specifically, the pin adjustment mechanism 80 includes vertical slots 81 on both sides of the carrier 32, a pin adjustment bracket 82 fixed between the coil adjustment mechanism 70 and the paint stripping mechanism 33, a pin adjustment lifting plate 83 that can be raised and lowered on the pin adjustment bracket 82, two sets of pin adjustment grippers 84 symmetrically arranged on both sides of the pin adjustment lifting plate 83, a pressure block 85 that can be raised and lowered between the two sets of pin adjustment grippers 84, a first pin adjustment cylinder 86 for driving the pin adjustment lifting plate 83 to rise and fall vertically, a second pin adjustment cylinder 87 for driving the pin adjustment grippers 84 to open and close, and a third pin adjustment cylinder 88 for driving the pressure block 85 to rise and fall vertically.

[0087] The carrier 32 has a carrier groove 321 for carrying the electromagnetic coil 200. Two vertical grooves 81 are located on both sides of the carrier groove 321 and are connected to the carrier groove 321. The second pin adjustment cylinder 87 drives the pin adjustment gripper 84 to close so that the pin 210 is perpendicular to the end plane of the electromagnetic coil 200. The third pin adjustment cylinder 88 drives the pressure block 85 to descend and press the pin 210 at least partially into the vertical groove 81.

[0088] During operation, the paint stripping conveyor line 31 transports the carrier 32 carrying the electromagnetic coil 200 to the pin adjustment bracket 82. The pin adjustment lifting plate 83, driven by the first pin adjustment cylinder 86, descends to a suitable position, placing the pin 210 within the clamping range of the pin adjustment gripper 84. Subsequently, the second pin adjustment cylinder 87 drives the pin adjustment gripper 84 to open and close, clamping and adjusting the pin 210 to ensure that the pin 210 remains perpendicular to the end plane of the electromagnetic coil 200. Then, the third pin adjustment cylinder 88 drives the pressure block 85 to descend vertically, pressing the pin 210 at least partially into the vertical groove 81. Finally, the pressure block 85, the pin adjustment gripper 84, and the pin adjustment lifting plate 83 all reset to prepare for the next pin 210 adjustment operation.

[0089] It should be noted that during the paint stripping process, usually only two-thirds of the vertical portion of pin 210 needs to be stripped to meet the requirements of subsequent electrical connections. Therefore, the portion of pin 210 pressed into the vertical groove 81 cannot be processed by the paint stripping mechanism 33 and will not affect its performance.

[0090] Furthermore, referring to Figure 12 The unloading mechanism 40 includes an unloading conveyor line 41 fixedly disposed on one side of the paint stripping conveyor line 31 and a material sensing mechanism 42 disposed on the unloading conveyor line 41. The material sensing mechanism 42 is electrically connected to the control mechanism and is used to sense whether there is material on the unloading conveyor line 41.

[0091] When the second transfer mechanism 60 transfers the stripped electromagnetic coil 200 to the unloading conveyor line 41, the material presence sensing mechanism 42 detects the presence of material and sends a signal to the control mechanism. Upon receiving the signal, the control mechanism drives the unloading conveyor line 41 to operate normally, thereby completing the unloading process. Conversely, if the material presence sensing mechanism 42 fails to detect the electromagnetic coil 200, the control mechanism will instruct the unloading conveyor line 41 to stop operating or operate at a low speed.

[0092] Furthermore, referring to Figure 3 , Figure 18 and Figure 19 The first transfer mechanism 50 includes a first transfer bracket 51 fixedly mounted on the machine body 110 and a first transfer manipulator 52 rotatably mounted on the first transfer bracket 51. The first transfer bracket 51 is located between the feeding mechanism 10, the bending module 20 and the paint stripping module 30. The first transfer manipulator 52 includes at least one first transfer gripper 521 for holding the electromagnetic coil 200.

[0093] The second transfer mechanism 60 includes a second transfer bracket 61 fixedly disposed at the unloading mechanism 40 and a second transfer manipulator 62 slidably disposed on the second transfer bracket 61. The second transfer manipulator 62 can move back and forth between the unloading mechanism 40 and the paint stripping conveyor line 31. The second transfer manipulator 62 includes at least one second transfer gripper 621 for holding the electromagnetic coil 200, and the second transfer gripper 621 is provided with an insertion groove 622 for the pin 210 to pass through at the position corresponding to the pin 210.

[0094] During operation, the first transfer robot 52, through its first transfer gripper 521, can precisely hold the electromagnetic coil 200, achieving efficient transfer of the electromagnetic coil 200 between the loading mechanism 10, bending module 20, and paint stripping module 30. The second transfer robot 62 focuses on transferring the electromagnetic coil 200 from the paint stripping module 30 to the unloading mechanism 40. By sliding the second transfer robot 62 on the second transfer bracket 61, the second transfer robot 62 can move quickly and smoothly between the unloading mechanism 40 and the paint stripping conveyor line 31. At the same time, the insertion groove 622 allows the pin 210 to smoothly pass through the insertion groove 622 during the transfer process, avoiding damage to the pin 210 and ensuring the overall stability of the electromagnetic coil 200.

[0095] In this embodiment, the first transfer gripper 521 of the first transfer robot 52, the second transfer gripper 621 of the second transfer mechanism 60, and the bending module 20 are all in two sets to further improve production efficiency.

[0096] Reference Figure 20 In another aspect, this application also provides a method of using the bending and paint stripping equipment 100 for electromagnetic coils, which is applicable to the bending and paint stripping equipment 100 for electromagnetic coils 200 as described above, comprising the following steps:

[0097] 101. The electromagnetic coil 200 is conveyed to the first preset position 120 by the feeding mechanism 10, and the electromagnetic coil 200 at the first preset position 120 is transferred to the bending mechanism 23 by the first transfer mechanism 50.

[0098] 102. The electromagnetic coil 200 is positioned by the positioning mechanism 22, and then the pin 210 of the electromagnetic coil 200 is bent by the bending mechanism 23.

[0099] 103. The bent pins 210 are trimmed by the pin trimming mechanism 24, and the waste generated during the trimming process is collected by the waste collection mechanism 25.

[0100] 104. The electromagnetic coil 200 is transferred to the coil adjustment mechanism 70 by the first transfer mechanism 50. The position of the electromagnetic coil 200 is adjusted by the coil adjustment mechanism 70, and the adjusted electromagnetic coil 200 is placed on the carrier 32 on the paint stripping conveyor line 31, ensuring that the pin 210 is located at the upper position of the electromagnetic coil 200.

[0101] 105. The carrier 32 is transported to the pin adjustment mechanism 80 via the paint stripping conveyor line 31. The pin adjustment mechanism 80 adjusts the perpendicularity of the pin 210 so that the pin 210 is perpendicular to the end plane of the electromagnetic coil 200.

[0102] 106. The carrier 32 is transported to the laser paint stripping mechanism 33 via the paint stripping conveyor line 31, and the paint stripping mechanism 33 strips the paint from the pin 210.

[0103] 107. The carrier 32 is transported to the second preset position 130 by the paint stripping conveyor line 31, and the second transfer mechanism 60 transfers the electromagnetic coil 200 on the carrier 32 to the unloading mechanism 40 to achieve the final unloading.

[0104] Working principle: During operation, the feeding mechanism 10 automatically transports the electromagnetic coil 200 to the first preset position 120. At this time, the first transfer robot 52 of the first transfer mechanism 50 operates, gripping the electromagnetic coil 200 and transferring it to the bending module 20. The positioning mechanism 22 positions the electromagnetic coil 200 to prevent it from shifting. Subsequently, the bending mechanism 23 performs a precise bending operation on the leads 210 of the electromagnetic coil 200.

[0105] After bending is completed, the bending mechanism 23 returns to its initial state, making way for the waste collection mechanism 25. Then, the trimming mechanism trims the bent pins 210 to ensure that the length of the pins 210 meets the requirements of subsequent processes. Simultaneously, the waste collection mechanism 25 collects the waste generated during the trimming process to maintain a clean working environment.

[0106] Subsequently, the electromagnetic coil 200 is transferred to the coil adjustment mechanism 70 by the first transfer robot 52. The coil adjustment mechanism 70 adjusts the position of the pin 210 relative to the electromagnetic coil 200 to ensure that the pin 210 is located at the upper part of the electromagnetic coil 200, so as to facilitate the subsequent paint removal operation.

[0107] After the pin 210 position is adjusted, the electromagnetic coil 200 is steadily placed on the carrier 32 on the paint stripping conveyor line 31. As the paint stripping conveyor line 31 operates, the carrier 32 and the electromagnetic coil 200 are transported to the pin adjustment mechanism 80. The pin adjustment mechanism 80 precisely adjusts the perpendicularity of the pin 210 to ensure that the pin 210 and the electromagnetic coil 200 remain perpendicular to each other, thereby improving the paint stripping effect.

[0108] After the pin 210 is adjusted, the paint stripping conveyor line 31 transports the carrier 32 and the electromagnetic coil 200 to the paint stripping mechanism 33, where the paint stripping mechanism 33 strips the paint from the pin 210. After the paint stripping is completed, the carrier 32 continues to move along the paint stripping conveyor line 31 until it reaches the second preset position 130.

[0109] Finally, the second transfer robot 62 of the second transfer mechanism 60 transfers the electromagnetic coil 200 at the second preset position 130 to the unloading mechanism 40. After receiving the electromagnetic coil 200, the unloading mechanism 40 transports it to the designated position via the unloading conveyor line 41, completing the final unloading operation.

[0110] The above is only used to illustrate the technical solution of the present invention and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and scope of the technical solution of the present invention, should be covered within the scope of the claims of the present invention.
