Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electromagnetic element production equipment, in particular to a bending and paint stripping device for electromagnetic coils and a use method thereof. BACKGROUND

[0002] As a core component for converting electrical energy and magnetic energy, electromagnetic coils are widely used in relays, sensors, motors, and various inductive devices. In the final stage of the manufacturing process, two key processes are usually required for the pins of the coil: first, the straight pins are precisely bent into a specific shape (such as 90° or an acute angle) to meet the installation requirements on the circuit board or the connection requirements with other wires; second, the bent pins are subjected to paint stripping treatment to remove the surface insulating paint layer, ensuring the electrical conductivity for subsequent welding or connection.

[0003] Currently, most manufacturers use a step-by-step processing method to manufacture the pins of electromagnetic coils. In this process, the operator first uses a dedicated bending clamp or a semi-automatic bending machine to shape the pins. After bending, the workpiece is transferred to a separate paint stripping station for processing, and the paint stripping methods include mechanical scraping, chemical soaking, or laser burning, etc.

[0004] However, this decentralized production mode of "bending-transferring-paint stripping" has significant problems. Frequent clamping and transferring disrupts the production process, resulting in low overall efficiency, which is not easy to adapt to modern automated production lines. At the same time, the high dependence on manual operation increases labor costs and exposes the operators to safety hazards of contacting chemical paint strippers or laser equipment. SUMMARY

[0005] The purpose of the present application is to provide a bending and paint stripping device for electromagnetic coils and a use method thereof, which can automatically bend and strip the pins, improve production efficiency and automation level, reduce labor costs, and improve production safety.

Block, and a bending motor for driving the rotating seat to rotate so that the bending block cooperates with the center column to bend the pins; the paint stripping module is used to strip the paint of the pins of the electromagnetic coil after bending, including a paint stripping conveyor line, a carrier provided on the paint stripping conveyor line for carrying the electromagnetic coil, and two sets of paint stripping mechanisms symmetrically provided on both sides of the paint stripping conveyor line and used to strip the paint of the pins of the electromagnetic coil. After the paint stripping is completed, the paint stripping conveyor line is used to convey the electromagnetic coil to a second preset position; the unloading mechanism is used to unload the electromagnetic coil that has completed paint stripping; the first transferring mechanism is used to transfer the electromagnetic coil conveyed to the first preset position by the loading mechanism to the bending module, so that the bending mechanism bends its pins, and then transfers the electromagnetic coil after the pins are bent to the paint stripping module; the second transferring mechanism is used to transfer the electromagnetic coil at the second preset position to the unloading mechanism to achieve final unloading.

[0007] The present application also provides a method for using a bending and paint stripping device for an electromagnetic coil, which is applicable to the bending and paint stripping device for an electromagnetic coil as described above, and includes the following steps: The electromagnetic coil is transported to the first preset position by the loading mechanism, and the first transfer mechanism transfers the electromagnetic coil at the first preset position to the bending mechanism; The electromagnetic coil is positioned by a positioning mechanism, and then the pins of the electromagnetic coil are bent by a bending mechanism; The bent pins are trimmed by the pin trimming mechanism, and the waste generated during the trimming process is collected by the waste collection mechanism; 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; The carrier is transported to the pin adjustment mechanism through the paint stripping conveyor line, and the pin adjustment mechanism adjusts the verticality of the pin so that the pin remains perpendicular to the end plane of the electromagnetic coil; The carrier is conveyed to the laser paint stripping mechanism through the paint stripping conveying line, and the paint stripping mechanism strips the pins; The carrier is conveyed to the second preset position through the paint stripping conveying line, and the second carrier moving mechanism moves the electromagnetic coil on the carrier to the discharging mechanism to realize final discharging.

[0015] The present embodiment provides a bending and paint stripping device for electromagnetic coil, which is used for bending and paint stripping the pin 210 of the electromagnetic coil 200, as shown in Figure 1 and Figure 2 respectively show two electromagnetic coils 200, wherein Figure 1 shows the electromagnetic coil 200 without bending and paint stripping treatment, Figure 2 is the electromagnetic coil 200 after the treatment of the bending and paint stripping device 100 provided by the present application, wherein the pin 210 of the electromagnetic coil 200 without bending and paint stripping treatment extends outward along the direction parallel to the end plane of the electromagnetic coil 200, and the pin 210 of the electromagnetic coil 200 after the treatment of the bending and paint stripping device 100 extends outward along the direction perpendicular to the end plane of the electromagnetic coil 200.

[0016] Referring to Figure 3The bending paint stripping device 100 provided by the application comprises a machine body 110, and an upper feeding mechanism 10, a bending module 20, a paint stripping module 30, a lower feeding mechanism 40, a first transfer mechanism 50, a second transfer mechanism 60 and a control mechanism arranged on the machine body 110, wherein the upper feeding mechanism 10 is used for conveying the electromagnetic coil 200 to a first preset position 120; the bending module 20 is used for bending the pin 210 of the electromagnetic coil 200; the paint stripping module 30 is used for stripping the pin 210 of the bent electromagnetic coil 200 and conveying the electromagnetic coil 200 after stripping to a second preset position 130; the lower feeding module is used for feeding the electromagnetic coil 200 after stripping; the first transfer mechanism 50 is used for transferring the electromagnetic coil 200 conveyed by the upper feeding mechanism 10 to the first preset position 120 to the bending module 20, so that the bending module 20 bends the pin 210 thereof, and then transfers the electromagnetic coil 200 after the pin 210 is bent to the paint stripping module 30; the second transfer mechanism 60 is used for transferring the electromagnetic coil 200 at the second preset position 130 to the lower feeding mechanism 40 to realize final feeding; and the control mechanism is electrically connected with the upper feeding mechanism 10, the bending module 20, the paint stripping module 30, the lower feeding mechanism 40, the first transfer mechanism 50 and the second transfer mechanism 60, so as to control the upper feeding mechanism 10, the bending module 20, the paint stripping module 30, the lower feeding mechanism 40, the first transfer mechanism 50 and the second transfer mechanism 60 to work cooperatively, and realize automatic feeding, bending, paint stripping and feeding of the electromagnetic coil 200.

[0017] In work, first, the electromagnetic coil 200 is conveyed to the first preset position 120 by the upper feeding mechanism 10, and the electromagnetic coil 200 at the first preset position 120 is transferred to the bending module 20 by the first transfer mechanism 50 to perform pin 210 bending operation. The bending module 20 accurately bends the pin 210 of the electromagnetic coil 200 according to the preset bending parameters, so as to ensure that the shape of the pin 210 meets the subsequent assembly requirements. After the pin 210 bending is completed, the first transfer mechanism 50 transfers the bent electromagnetic coil 200 to the paint stripping module 30. The bent pin 210 is stripped by the paint stripping module 30, and after the stripping is completed, the electromagnetic coil 200 is conveyed to the second preset position 130. At this time, the second transfer mechanism 60 stably transfers the electromagnetic coil 200 at the second preset position 130 to the lower feeding mechanism 40. The lower feeding mechanism 40 feeds the electromagnetic coil 200 after stripping, so as to facilitate subsequent manual taking or automatic assembly. In the whole process, the control mechanism controls the upper feeding mechanism 10, the bending module 20, the paint stripping module 30, the lower feeding mechanism 40, the first transfer mechanism 50 and the second transfer mechanism 60 to work cooperatively, so as to ensure that the whole bending paint stripping process is efficient, stable and reliable.

[0018] Further, with reference to Figure 4The feeding mechanism 10 comprises a feeding conveying line 11 arranged on the machine body 110 and a plurality of carrier plates 12 arranged uniformly on the feeding conveying line 11. One end of the feeding conveying line 11 is a feeding end 111, and the other end is a discharging end 112. A first preset position 120 is located on the side of the feeding conveying line 11 close to the discharging end. A plurality of placement grooves 121 for placing the electromagnetic coils 200 are arranged on the carrier plates 12. In the specific implementation process, the electromagnetic coils 200 can be placed in the placement grooves 121 of the carrier plates 12 at the feeding end 111 by manual or mechanical hand, so as to realize the feeding of the electromagnetic coils 200.

[0019] In addition, the feeding mechanism 10 further comprises a feeding induction assembly 13 arranged at the first preset position 120 for inducting the electromagnetic coils 200. The feeding induction assembly 13 comprises a feeding induction support 131 and a feeding induction sensor arranged on the feeding induction support 131. The feeding induction sensor is electrically connected with the control mechanism. When the feeding conveying line 11 conveys the electromagnetic coils 200 to the first preset position 120, the feeding induction sensor 132 senses that there is material, sends a signal to the control mechanism, and the control mechanism controls the feeding conveying line 11 to stop conveying, so that the electromagnetic coils 200 stay at the first preset position 120 and wait to be moved by the first moving mechanism 50 to the bending module 20 for bending operation. If the feeding induction sensor 132 senses that there is no material, the control mechanism continues to control the feeding conveying line 11 to convey until the next electromagnetic coil 200 is conveyed to the first preset position 120.

[0020] Further, referring to Figure 1 and Figure 5 , the bending module 20 comprises a bending fixing frame 21 fixedly arranged on the machine body 110, a positioning mechanism 22 arranged on the bending fixing frame 21 for positioning the electromagnetic coils 200, and a bending mechanism 23 arranged on the bending fixing frame 21 for bending the pins 210 of the electromagnetic coils 200.

[0021] The positioning mechanism 22 is used for accurately positioning the electromagnetic coils 200, so as to ensure that the electromagnetic coils 200 remain fixed during the bending process, prevent movement or deviation of the electromagnetic coils 200, and thus affect the accuracy and quality of the bending.

[0022] Specifically, referring to Figure 5 , Figure 6 and Figure 7 , the positioning mechanism 22 comprises two positioning seats 221 fixedly arranged on the bending fixing frame 21, a first positioning assembly slidingly arranged on the bending fixing frame 21 for positioning the electromagnetic coils 200 from a first direction, and a second positioning assembly for positioning the electromagnetic coils 200 from a second direction. The two positioning seats 221 cooperatively form a positioning groove for positioning the electromagnetic coils 200, and the positioning groove has an opening facing the first positioning assembly.

[0023] The first positioning assembly comprises a first sliding plate 222 slidingly arranged on the bending fixing frame 21 and a first positioning driving cylinder for driving the first sliding plate 222 to move along a first direction towards or away from the positioning seat 221 so as to abut the electromagnetic coil 200 against the side walls of the two positioning seats 221. The first sliding plate 222 is provided with a first abutting portion 224 corresponding to the position of the electromagnetic coil 200.

[0024] The second positioning assembly comprises a second sliding plate 225 slidingly arranged on the top of the bending fixing frame 21, a lifting plate 226 vertically arranged on the bottom side of the second sliding plate 225 along a second direction, a second positioning driving cylinder 227 for driving the second sliding plate 225 to move to the directly above of the positioning seat 221, and a positioning lifting cylinder 228 for driving the lifting plate 226 to vertically lift along the second direction relative to the second sliding plate 225. The bottom side of the lifting plate 226 is provided with a second abutting portion 229 abutting against the electromagnetic coil 200.

[0025] In operation, first, the second sliding plate 225 is driven by the second positioning driving cylinder 227 to move, so that the second sliding plate 225 moves from the directly above of the positioning seat 221 to the obliquely above of the positioning seat 221, thereby providing a space for the first moving mechanism 50 to move the electromagnetic coil 200 into the positioning groove formed by the two positioning seats 221. At this time, the first sliding plate 222 is driven by the first positioning driving cylinder to move along the first direction towards the positioning seat 221, so that the first abutting portion 224 of the first sliding plate 222 abuts against the side wall of the electromagnetic coil 200, thereby achieving the positioning of the electromagnetic coil 200 in the first direction. At the same time, the second sliding plate 225 is driven by the second positioning cylinder to move, so that the second sliding plate 225 moves to the directly above of the positioning seat 221, and then the lifting plate 226 is driven by the positioning lifting cylinder 228 to vertically descend along the second direction, so that the second abutting portion 229 of 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 and ensuring the stability of the electromagnetic coil 200 to guarantee the bending precision.

[0026] Further, with reference to Figure 6 , Figure 8 , Figure 9 and Figure 10The bending mechanism 23 comprises a lifting frame 231 arranged on the bending fixing frame 21, a rotating seat 232 arranged on the lifting frame 231, a center column 233 arranged at the center of the rotating seat 232, a bending block 234 arranged on the rotating seat 232 and located at one side of the center column 233 and used for inserting into the gap between the pin 210 and the electromagnetic coil 200, and a bending motor 235 used for driving the rotating seat 232 to rotate so as to make the bending block 234 cooperate with the center column 233 to bend the pin 210. The bending fixing frame 21 is provided with a bending lifting cylinder 236 used for driving the lifting frame 231 to vertically lift relative to the bending fixing frame 21.

[0027] When the electromagnetic coil 200 is positioned from the first direction and the second direction by the first positioning assembly and the second positioning assembly respectively, the bending lifting cylinder 236 drives the lifting seat to ascend, the rotating block on the rotating seat 232 is inserted into the gap between the electromagnetic coil 200 and the pin 210, and the center column 233 is located at the side of the pin 210 away from the electromagnetic coil 200. At this time, the rotating seat 232 is driven to rotate by the bending motor 235, the center column 233 and the bending block 234 are driven to rotate, so that the bending block 234 and the center column 233 cooperate to bend the pin 210. After the bending is completed, the bending lifting cylinder 236 drives the lifting seat to descend again, so that the rotating seat 232 and the components thereon are reset, so as to perform the next bending operation.

[0028] In addition, referring to Figure 8 In the embodiment, in order to improve the bending precision, a connecting shaft 237 is connected between the output shaft of the bending motor 235 and the rotating seat 232. The connecting shaft 237 is provided with an induction ring with a notch, the arc length of the notch corresponds to the preset bending angle of the pin 210. The bending induction sensor 239 is arranged at the position corresponding to the induction ring of the lifting frame 231, and the bending induction sensor 239 is electrically connected with the control mechanism. In the initial state, the starting end of the notch of the induction ring is located in the induction area of the bending induction sensor 239. When the rotating seat 232 is driven to rotate by the bending motor 235 to make the bending block 234 cooperate with the center column 233 to bend the pin 210, the connecting shaft 237 is rotated to drive the induction ring to rotate. When the terminal end of the notch of the induction ring is rotated to the induction area of the bending induction sensor 239, the bending induction sensor 239 senses the induction ring again at this time, and then the bending induction sensor 239 sends a signal to the control mechanism, and the control mechanism controls the bending motor 235 to stop rotating, so as to realize the accurate control of the bending angle of the pin 210.

[0029] Further, referring to Figure 5 and Figure 6 The bending module 20 further comprises a pin trimming mechanism 24 used for trimming the bent pin 210 and a waste collecting mechanism 25 used for collecting the waste generated when the pin 210 is trimmed.

[0030] The pin trimming mechanism 24 trims the bent pin 210 to keep the length of the pin 210 consistent, thereby improving the quality of the finished product and preventing the length of the pin 210 from being inconsistent. The waste collecting mechanism 25 is used to collect the waste generated during trimming, keep the working environment clean, and avoid pollution of the working area caused by the accumulation of waste.

[0031] Further, with reference to Figure 5 , Figure 6 and Figure 11 , the pin trimming mechanism 24 includes a fixed plate 241 fixed on one side of the bending fixing frame 21, a shearing assembly 242 slidingly arranged on the fixed plate 241, and a trimming cylinder 243 for driving the shearing assembly 242 to move towards 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 towards the bending fixing frame 21, the shearing part 2421 of the shearing assembly 242 can trim the bent pin 210.

[0032] In this embodiment, the shearing assembly 242 is a gas shearing device, which includes a shearing part 2421 and a pneumatic driving structure for driving the shearing part 2421. In other embodiments, it can also be a hydraulic shearing device or other shearing device capable of achieving the shearing function, which will not be described in detail here.

[0033] After bending is completed, the pin trimming mechanism 24 starts to work, the trimming cylinder 243 drives the shearing assembly 242 to move towards the bending fixing frame 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 remains consistent. After shearing is completed, the trimming cylinder 243 drives the shearing assembly 242 to move away from the bending fixing frame 21, in order to prepare for the trimming of the next pin 210.

[0034] Further, the waste collecting mechanism 25 includes a waste fixing frame 251 fixed on the bending fixing frame 21, a waste guide cylinder 252 movably arranged between the waste fixing frame 251 and the pin trimming mechanism 24, a waste collecting box 253 arranged on the waste fixing frame 251 for receiving the waste dropped by the waste guide cylinder 252, and a waste collecting cylinder 254 for driving the waste guide cylinder 252 to move towards or away from the pin trimming mechanism 24.

[0035] Specifically, the waste fixing frame 251 is fixed on one side of the bending mechanism 23, the cylinder body of the waste collecting cylinder 254 is fixedly installed on the waste fixing frame 251, the waste guide cylinder 252 is obliquely arranged, the top end of the waste guide cylinder 252 is used for extending into the mechanism of the pin 210 and receiving the waste generated during shearing, the bottom end is fixedly installed on the piston rod of the waste collecting cylinder 254, and the waste collecting box 253 is an open box.

[0036] After the bending is completed, first, the lifting frame 231 is reset to the initial position to give way to the waste guide cylinder 252, so that the waste collecting cylinder can smoothly extend in, the shearing assembly 242 is driven by the trimming cylinder 243 to move towards the bending fixing frame 21, so that the bent pin 210 part enters the shearing opening of the shearing part 2421, then the waste guide cylinder 252 is driven by the waste collecting cylinder 254 to extend into the shearing mechanism and be located below the pin 210, at this time, the top end opening of the waste guide cylinder 252 faces the shearing part 2421 of the shearing assembly 242 to receive the waste generated during shearing, then the shearing assembly 242 works to trim the pin 210, the waste generated during trimming falls into the waste guide cylinder 252, and then falls into the waste collecting box 253 through the waste guide cylinder 252, the trimming and waste collecting work is completed, finally, the shearing assembly 242 and the waste collecting assembly are reset to the initial state to prepare for the next trimming and waste collecting.

[0037] Further, referring to Figure 3 and Figure 12 , the paint stripping module 30 includes a paint stripping conveying line 31 arranged on the machine body 110, a carrier 32 arranged on the paint stripping conveying line 31 and used for carrying the electromagnetic coil 200, and two groups of paint stripping mechanisms 33 symmetrically arranged on both sides of the paint stripping conveying line 31 and used for stripping the pins 210 of the electromagnetic coil 200, and after the paint stripping is completed, the paint stripping conveying line 31 is used for conveying the electromagnetic coil 200 to the second preset position 130.

[0038] When the carrier 32 carrying the electromagnetic coil 200 moves to the paint stripping mechanism 33 under the conveying of the paint stripping conveying line 31, the paint stripping mechanism 33 strips the pins 210 of the electromagnetic coil 200, after the paint stripping is completed, the paint stripping conveying line 31 continues to convey, and the carrier 32 and the electromagnetic coil 200 are conveyed to the second preset position 130.

[0039] Further, referring to Figure 12 and Figure 13The paint stripping mechanism 33 comprises a paint stripping fixed plate 331 fixed on one side of the paint stripping conveying line 31, a paint stripping sliding plate 332 sliding on the paint stripping fixed plate 331, a paint stripping rotating frame 333 rotatably arranged on the paint stripping sliding plate 332, a laser paint stripping assembly 334 sliding on the paint stripping rotating frame 333, and a first paint stripping driving assembly for driving the paint stripping sliding plate 332 to move and a second paint stripping driving assembly for driving the laser paint stripping assembly 334 to move, and a laser emitting end of the laser paint stripping assembly 334 faces the paint stripping conveying line 31. The first paint stripping driving assembly is used to drive the paint stripping sliding plate 332 to slide along the length direction of the paint stripping conveying line 31, so as to adjust the position of the laser paint stripping assembly 334 relative to the paint stripping conveying line 31, and the second paint stripping driving assembly is used to drive the laser paint stripping assembly 334 to move towards or away from the paint stripping conveying line 31, so as to adjust the distance between the laser paint stripping assembly 334 and the paint stripping conveying line 31.

[0040] In some specific embodiments, referring to Figure 14 The paint stripping sliding plate 332 is connected to the paint stripping fixed plate 331 through a sliding rail 3311 and a sliding block 3312, the first paint stripping driving assembly comprises a paint stripping driving cylinder fixed on the paint stripping fixed plate 331, the paint stripping driving cylinder is arranged along the length direction of the paint stripping conveying line 31, and a piston rod of the paint stripping driving cylinder is fixedly connected to one side of the paint stripping sliding plate 332. The paint stripping driving cylinder drives the paint stripping sliding plate 332 to move along the length direction of the paint stripping conveying line 31, so as to adjust the position of the laser paint stripping assembly 334 relative to the paint stripping conveying line 31, thereby adjusting the paint stripping position.

[0041] In some specific embodiments, the laser paint stripping assembly 334 is connected to the paint stripping rotating frame 333 through a sliding groove and a sliding block structure, the second paint stripping driving assembly comprises a guide rod 336, a threaded rod 337 and a hand wheel 338, the hand wheel 338 is rotated to drive the threaded rod 337 to rotate, so as to drive the laser paint stripping assembly 334 to slide relative to the paint stripping rotating frame 333, that is, to move the laser paint stripping assembly 334 relative to the paint stripping rotating frame 333 towards or away from the paint stripping conveying line 31, thereby adjusting the distance between the laser paint stripping assembly 334 and the paint stripping conveying line 31, so as to adjust the laser intensity emitted by the laser emitting end of the laser paint stripping assembly 334. In other embodiments, the second paint stripping driving assembly can also adopt a cylinder driving structure or a lead screw motor transmission structure, which is not limited here.

[0042] In addition, in the embodiment, the paint stripping rotating frame 333 is connected to the paint stripping sliding plate 332 through an angle adjusting mechanism 339, which is used to adjust the laser emitting angle of the laser paint stripping assembly 334. The number of the angle adjusting mechanism 339 is two groups, and the two groups of angle adjusting mechanism 339 are symmetrically arranged on two sides of the paint stripping rotating frame 333.

[0043] Specifically, the angle adjusting mechanism 339 comprises a first adjusting seat 3391 fixed on the paint stripping sliding plate 332, an adjusting groove 3392 opened on the paint stripping rotating frame 333, an adjusting block 3393 slidingly arranged in the adjusting groove 3392, a second adjusting seat 3394 fixed on the paint stripping sliding plate 332, and an adjusting screw 3395 for connecting the adjusting block 3393 and the second adjusting seat 3394. The paint stripping rotating frame 333 is rotatably connected to the first adjusting seat 3391 through a rotating shaft at one end close to the paint stripping conveying line 31. The adjusting block 3393 is provided with a through hole for the adjusting screw 3395 to pass through. The second adjusting seat 3394 is correspondingly provided with a screw hole. The bottom end of the adjusting screw 3395 is threadedly connected to the screw hole after passing through the through hole, so as to realize the connection between the adjusting block 3393 and the second adjusting seat 3394, and further realize the locking of the rotating angle of the paint stripping rotating frame 333.

[0044] Further, referring to Figure 12 and Figure 15 , the coil adjusting mechanism 70 is arranged between the bending module 20 and the paint stripping module 30, and is used for adjusting the position of the pin 210 relative to the electromagnetic coil 200, so as to ensure that the pin 210 is located at the upper part of the electromagnetic coil 200 to facilitate the paint stripping of the paint stripping mechanism 33.

[0045] It should be noted that in the present embodiment, when the paint stripping mechanism 10 delivers the electromagnetic coil 200 to the first preset position 120, the pin 210 is located at the lower part of the electromagnetic coil 200, which is to facilitate the bending of the pin 210 by the bending mechanism 23. However, when paint stripping, if the pin 210 is still located at the lower part of the electromagnetic coil 200, the paint stripping effect of the paint stripping mechanism 33 on the pin 210 is poor. Therefore, the coil adjusting mechanism 70 is arranged to adjust the position of the pin 210 relative to the electromagnetic coil 200, so as to ensure that the pin 210 is located at the upper part of the electromagnetic coil 200, thereby facilitating the paint stripping of the paint stripping mechanism 33 on the pin 210 and ensuring the paint stripping effect.

[0046] Specifically, referring to Figure 15The coil adjusting mechanism 70 comprises a coil adjusting fixed frame 71 arranged on one side of the paint stripping conveying line 31, a coil adjusting lifting seat 72 vertically arranged on the coil adjusting fixed frame 71, a coil adjusting bearing seat 73 rotatably arranged on the coil adjusting lifting seat 72, a coil adjusting positioning plate 74 movably arranged on the coil adjusting bearing seat 73 for positioning the electromagnetic coil 200, a coil adjusting lifting cylinder 75 for driving the coil adjusting lifting seat 72 to vertically lift, a coil adjusting overturning cylinder 76 (or an overturning motor) for driving the coil adjusting bearing seat 73 to overturn, and a coil adjusting cylinder 77 for driving the coil adjusting positioning plate 74 to move relative to the coil adjusting bearing seat 73 so as to fix or release the electromagnetic coil 200 on the coil adjusting bearing seat 73. The coil adjusting bearing seat 73 is provided with a receiving groove 731 for accommodating the electromagnetic coil 200, and is vertically arranged above the paint stripping conveying line 31 and can be overturned in the vertical direction under the driving of the coil adjusting overturning cylinder 76 so as to adjust the position of the pin 210 relative to the electromagnetic coil 200. The coil adjusting positioning plate 74 moves relative to the coil adjusting bearing seat 73 under the driving of the coil adjusting cylinder 77 so as to fix or release the electromagnetic coil 200 on the coil adjusting bearing seat 73.

[0047] In operation, the first transfer mechanism 50 places the bent electromagnetic coil 200 into the receiving groove 731 of the coil adjusting bearing seat 73, and at this time, the pin 210 is located at the lower part of the electromagnetic coil 200. The coil adjusting positioning plate 74 is driven by the coil adjusting cylinder 77 to move into the receiving groove 731, so as to stably clamp the electromagnetic coil 200 on the coil adjusting bearing seat 73. Subsequently, the coil adjusting overturning cylinder 76 is started to drive the coil adjusting bearing seat 73 to overturn 180° in the vertical direction, thereby driving the electromagnetic coil 200 to overturn 180°, so that the pin 210 is located at the upper part of the electromagnetic coil 200. Then, the coil adjusting lifting cylinder 75 is started to drive the coil adjusting lifting seat 72 and the coil adjusting bearing seat 73 to descend together. The coil adjusting positioning plate 74 is driven by the coil adjusting cylinder 77 to move away from the receiving groove 731, so as to stably drop the electromagnetic coil 200 onto the carrier 32 which is previously moved to be directly below the coil adjusting bearing seat 73. Finally, the coil adjusting lifting cylinder 75 drives the coil adjusting lifting seat 72 to ascend, and the coil adjusting overturning cylinder 76 drives the coil adjusting bearing seat 73 to reset, so as to prepare for the next adjustment of the electromagnetic coil 200.

[0048] Further, referring to Figure 12 , Figure 16 and Figure 17 , the coil adjusting mechanism 70 and the paint stripping mechanism 33 are further provided with a pin adjusting mechanism 80 for adjusting the verticality of the pin 210 relative to the end plane of the electromagnetic coil 200.

[0049] It should be noted that in the actual production process, the bending angle of the pin 210 will inevitably have some errors, which will cause the pins 210 on both sides of the electromagnetic coil 200 to deviate greatly, thereby affecting the subsequent paint stripping effect. Therefore, the pin adjusting mechanism 80 is arranged to adjust the perpendicularity of the pin 210 relative to the end plane of the electromagnetic coil 200, so as to improve the paint stripping effect of the pin 210.

[0050] Specifically, the pin adjusting mechanism 80 includes vertical grooves 81 opened on both sides of the carrier 32, a pin adjusting bracket 82 fixedly arranged between the coil adjusting mechanism 70 and the paint stripping mechanism 33, a pin adjusting lifting plate 83 arranged on the pin adjusting bracket 82 in a liftable manner, two groups of pin adjusting clamping jaws 84 symmetrically arranged on both sides of the pin adjusting lifting plate 83, a pressing block 85 arranged between the two groups of pin adjusting clamping jaws 84 in a liftable manner, a first pin adjusting cylinder 86 for driving the pin adjusting lifting plate 83 to vertically lift, a second pin adjusting cylinder 87 for driving the pin adjusting clamping jaws 84 to open and close, and a third pin adjusting cylinder 88 for driving the pressing block 85 to vertically lift.

[0051] The carrier 32 is provided with a carrying groove 321 for carrying the electromagnetic coil 200, and the two vertical grooves 81 are located on both sides of the carrying groove 321 and communicate with the carrying groove 321. The second pin adjusting cylinder 87 drives the pin adjusting clamping jaws 84 to close so that the pin 210 is kept perpendicular to the end plane of the electromagnetic coil 200. The third pin adjusting cylinder 88 drives the pressing block 85 to descend and at least partially press the pin 210 into the vertical groove 81.

[0052] In operation, the paint stripping conveying line 31 conveys the carrier 32 carrying the electromagnetic coil 200 to the pin adjusting bracket 82. The pin adjusting lifting plate 83 is lowered to a suitable position under the drive of the first pin adjusting cylinder 86, so that the pin 210 is located within the clamping range of the pin adjusting clamping jaws 84. Then, the second pin adjusting cylinder 87 drives the pin adjusting clamping jaws 84 to open and close, so as to adjust the clamping of the pin 210 and ensure that the pin 210 is kept perpendicular to the end plane of the electromagnetic coil 200. Then, the third pin adjusting cylinder 88 drives the pressing block 85 to vertically descend, so as to at least partially press the pin 210 into the vertical groove 81. Finally, the pressing block 85, the pin adjusting clamping jaws 84 and the pin adjusting lifting plate 83 are all reset for the next pin 210 adjustment operation.

[0053] It should be noted that in the paint stripping process, only two-thirds of the pin 210 in the vertical direction need to be stripped, which can meet the requirements of subsequent electrical connection. Therefore, the part of the pin 210 pressed into the vertical groove 81 cannot be processed by the paint stripping mechanism 33, and will not affect its use effect.

[0054] Further, referring to Figure 12 , the discharging mechanism 40 includes a discharging conveying line 41 fixed on one side of the paint stripping conveying line 31 and a material sensing mechanism 42 arranged on the discharging conveying line 41, the material sensing mechanism 42 is electrically connected with the control mechanism, and is used for sensing whether there is material on the discharging conveying line 41.

[0055] When the second transfer mechanism 60 transfers the paint-stripped electromagnetic coil 200 to the discharging conveying line 41, the material sensing mechanism 42 detects the presence of the material, and immediately sends a signal to the control mechanism. After receiving the signal, the control mechanism drives the discharging conveying line 41 to operate normally, thereby completing the discharging process. Conversely, if the material sensing mechanism 42 fails to detect the electromagnetic coil 200, the control mechanism will instruct the discharging conveying line 41 to stop operating or operate at a low speed.

[0056] Further, referring to Figure 3 , Figure 18 and Figure 19 , the first transfer mechanism 50 includes a first transfer support 51 fixed on the machine body 110 and a first transfer manipulator 52 rotatably arranged on the first transfer support 51, the first transfer support 51 is located between the feeding mechanism 10, the bending module 20 and the paint stripping module 30, and the first transfer manipulator 52 includes at least one first transfer gripper 521 for clamping the electromagnetic coil 200. The second transfer mechanism 60 includes a second transfer support 61 fixed at the discharging mechanism 40 and a second transfer manipulator 62 slidingly arranged on the second transfer support 61, the second transfer manipulator 62 can move back and forth between the discharging mechanism 40 and the paint stripping conveying line 31, the second transfer manipulator 62 includes at least one second transfer gripper 621 for clamping the electromagnetic coil 200, and the second transfer gripper 621 is provided with a penetrating groove 622 corresponding to the position of the pin 210 for the pin 210 to penetrate.

[0057] In operation, the first transfer manipulator 52 can accurately clamp the electromagnetic coil 200 through the first transfer gripper 521, and efficiently transfer the electromagnetic coil 200 between the feeding mechanism 10, the bending module 20 and the paint stripping module 30. The second transfer manipulator 62 focuses on the transfer of the electromagnetic coil 200 from the paint stripping module 30 to the discharging mechanism 40. By slidingly arranging the second transfer manipulator 62 on the second transfer support 61, the second transfer manipulator 62 can quickly and smoothly move between the discharging mechanism 40 and the paint stripping conveying line 31. At the same time, through the arrangement of the penetrating groove 622, the pin 210 can smoothly penetrate the penetrating groove 622 during the transfer process, avoiding damage to the pin 210, and also ensuring the stability of the electromagnetic coil 200 as a whole.

[0058] In the embodiment, the first transfer gripper 521 of the first transfer mechanism 52, the second transfer gripper 621 of the second transfer mechanism 60, and the number of the bending modules 20 are all two groups, so as to further improve the production efficiency.

[0059] With reference to Figure 20 The application further provides a method for using the bending paint stripping device 100 for the electromagnetic coil, which is suitable for the bending paint stripping device 100 for the electromagnetic coil 200 as described above, and includes the following steps. 101. The electromagnetic coil 200 is transported to the first preset position 120 by the feeding mechanism 10, and the first transfer mechanism 50 transfers the electromagnetic coil 200 at the first preset position 120 to the bending mechanism 23; 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; 103. The bent pin 210 is trimmed by the pin trimming mechanism 24, and meanwhile, the waste generated in the trimming process is collected by the waste collecting mechanism 25; 104. The electromagnetic coil 200 is transferred to the coil adjusting mechanism 70 by the first transfer mechanism 50, the coil adjusting mechanism 70 is used to adjust the position of the electromagnetic coil 200, and the adjusted electromagnetic coil 200 is placed on the carrier 32 on the paint stripping conveying line 31, so as to ensure that the pin 210 is located at the upper position of the electromagnetic coil 200; 105. The carrier 32 is transported to the pin adjusting mechanism 80 by the paint stripping conveying line 31, the pin adjusting 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; 106. The carrier 32 is transported to the laser paint stripping mechanism 33 by the paint stripping conveying line 31, and the paint stripping mechanism 33 strips the pin 210; 107. The carrier 32 is transported to the second preset position 130 by the paint stripping conveying line 31, and the second transfer mechanism 60 transfers the electromagnetic coil 200 on the carrier 32 to the discharging mechanism 40, so as to realize the final discharging.

[0060] Working principle: when working, the feeding mechanism 10 automatically transports the electromagnetic coil 200 to the first preset position 120. At this time, the first transfer gripper 521 of the first transfer mechanism 50 works to clamp and transfer the electromagnetic coil 200 to the bending module 20. The positioning mechanism 22 is used to position the electromagnetic coil 200, so that the electromagnetic coil 200 is not easy to be displaced, and then the bending mechanism 23 is used to accurately bend the pin 210 of the electromagnetic coil 200.

[0061] After the bending, the bending mechanism 23 is reset to the initial state to make room for the waste collecting mechanism 25, and then the trimming mechanism trims the bent pin 210 to ensure that the length of the pin 210 meets the requirements of the subsequent process. At the same time, the waste collecting mechanism 25 collects the waste generated during the trimming process to keep the working environment clean.

[0062] Subsequently, the coil 200 is moved by the first transfer robot 52 to the coil adjusting mechanism 70. The coil adjusting mechanism 70 adjusts the position of the pin 210 relative to the coil 200 to ensure that the pin 210 is located at the upper position of the coil 200 to facilitate the subsequent paint removal operation.

[0063] After the position of the pin 210 is adjusted, the coil 200 is stably placed on the carrier 32 on the paint removal conveying line 31, and as the paint removal conveying line 31 operates, the carrier 32 and the coil 200 are conveyed to the pin adjusting mechanism 80. The pin adjusting mechanism 80 precisely adjusts the verticality of the pin 210 to ensure that the pin 210 remains vertical to the coil 200 to improve the paint removal effect.

[0064] After the pin 210 is adjusted, the paint removal conveying line 31 conveys the carrier 32 and the coil 200 to the paint removal mechanism 33 to remove the paint from the pin 210. After the paint removal is completed, the carrier 32 continues to move along the paint removal conveying line 31 until it reaches the second preset position 130.

[0065] Finally, the second transfer robot 62 of the second transfer mechanism 60 moves the coil 200 at the second preset position 130 to the unloading mechanism 40. After the unloading mechanism 40 receives the coil 200, it is conveyed to the designated position by the unloading conveying line 41 to complete the final unloading operation.

[0066] The above is only to illustrate the technical solutions of the present application and not to limit it. Other modifications or equivalent replacements to the technical solutions of the present application made by those skilled in the art should be covered within the scope of the claims of the present application as long as they do not deviate from the spirit and scope of the technical solutions of the present application.
