This realizes the automation and continuity of the process. However, this linear spatial arrangement fails to fully consider the needs of space optimization, limits the flexibility of the production layout, and causes the entire production line to occupy a large space, which is not conducive to space optimization of the production workshop. Summary of the Invention

[0008] By adopting this technical solution, a rotary feeder first drives the coil in precise circumferential motion. Subsequently, the first laser stripping machine in the upper stripping mechanism and the second laser stripping machine in the lower stripping mechanism operate synchronously to efficiently and comprehensively laser strip the top and bottom of the coil pins. This not only improves stripping efficiency but also ensures thoroughness and uniformity, effectively avoiding the blind spots that can occur with traditional stripping methods. The equipment also integrates welding and pin cutting functions, and automatically unloads the material after processing. The entire process is compact and streamlined, significantly improving production efficiency and operational flexibility, bringing revolutionary improvements to the coil processing industry. This equipment is not only compact and streamlined, but also significantly improves production efficiency and flexibility.

[0009] Optionally, the rotary feeding device includes a rotating disk, a rotating column and a rotating drive mechanism, the top of the rotating column is fixedly connected to the lower surface of the rotating disk, the bottom end of the rotating column is rotatably connected to the frame, the rotating drive mechanism is arranged inside the frame, and the rotating drive mechanism is used to drive the rotating column to rotate; a plurality of positioning jigs are arranged circumferentially on the rotating disk, and each of the positioning jigs is provided with a positioning flange for positioning the coil; a plurality of avoidance grooves are opened along the circumference of the rotating disk, and the avoidance grooves correspond one-to-one to the positioning jigs, and the avoidance grooves are located above or below the positioning jigs.

[0010] By adopting the above technical solution, the rotating disk, with its stable rotational connection with the frame by means of the rotating column fixed on its lower surface, not only ensures that the rotating disk can rotate smoothly under the action of the driving mechanism, but also, through the effective support of the rotating column, the rotating disk is maintained at an appropriate working height to meet the space requirements for coil operation in subsequent processing steps such as the visual inspection device, paint stripping device, laser welding device, pin cutting device, and blanking device, promotes smooth collaboration between various devices, and thus improves the operating efficiency and processing accuracy of the entire coil paint stripping and cutting integrated equipment. At the same time, the rotating disk is also provided with avoidance grooves corresponding to the positioning fixtures. These avoidance grooves are located above or below the positioning fixtures, providing the necessary operating space for key processes such as the paint stripping device, laser welding device, and pin cutting device, avoiding mutual interference between devices, and further improving the compactness of the equipment and the smoothness of operation.

[0011] Optionally, there are two laser welding devices, one laser welding device is used to weld the pins outside the coil, and the other laser welding device is used to weld the pins inside the coil; the laser welding device includes a transverse moving mechanism, a longitudinal moving mechanism, a first lifting mechanism, a pin clamping mechanism and a soldering mechanism, the transverse moving mechanism is arranged on the frame, the transverse moving mechanism is used to drive the longitudinal moving mechanism to move in a horizontal direction, the longitudinal moving mechanism is used to drive the first lifting mechanism to move in horizontal directions perpendicular to each other, the first lifting mechanism is used to drive the pin clamping mechanism and the soldering mechanism to rise and fall, the pin clamping mechanism is used to clamp the pins of the coil, and the soldering mechanism is used to weld the pins of the coil.

[0012] By adopting the above technical solution, the laser welding device utilizes a highly flexible and precise multi-axis motion mechanism, achieving efficient and accurate coil pin welding. The combined lateral and longitudinal motion mechanisms and the first lifting mechanism form a three-dimensional mobile platform, enabling precise adjustment of the relative position between the coil pins and the soldering mechanism from all directions and angles. The dual configuration of two laser welding devices allows for welding of the coil's external and internal pins, respectively. When the coil rotates with the rotating disk to the first laser welding device, the first laser welding device activates and precisely welds the coil's external pins. The coil then continues to rotate, and when it reaches the second laser welding device, the second laser welding device welds the coil's internal pins. This process eliminates the need for additional horizontal movement of the laser welding devices, significantly simplifying the operation and improving overall efficiency. Furthermore, because the welding operations are completed sequentially as the coil rotates, the coil processing process is highly automated, further improving production efficiency.

[0013] Optionally, the soldering mechanism includes a universal adjustment component and a solder pen, the universal adjustment component is arranged on the pin clamping mechanism, the solder pen is arranged on the universal adjustment component, and the universal adjustment component includes multiple adjustment parts, and two adjacent adjustment parts can slide or rotate relative to each other.

[0014] By adopting this technical solution, the soldering pen is mounted on a universal adjustment assembly, which includes multiple adjustment parts. Adjacent adjustment parts can both slide and rotate relative to each other, thus giving the soldering pen full freedom of adjustment in three dimensions. This not only enables the soldering pen to precisely reach every detail of the coil pins, but also allows it to easily handle complex and variable coil structures, ensuring high-quality and consistent soldering operations. It also simplifies the soldering process and improves work efficiency.

[0015] Optionally, the pin cutting device includes a second lifting mechanism and a pin cutting laser machine, the second lifting mechanism is arranged on the frame, the second lifting mechanism is used to drive the pin cutting laser machine to rise and fall, and the pin cutting laser machine is used to cut off the pins after soldering.

[0016] With this technical solution, after the coil pins are soldered to the laser welding device, the rotating disk continues to rotate to the pin cutting device. At this point, the second lifting mechanism activates, driving the pin cutting laser machine down to the appropriate height so that it can precisely align with the soldered pins. The pin cutting laser machine then emits a high-intensity laser beam, quickly and accurately severing the pins. This process not only ensures accurate and consistent pin cutting, but also effectively avoids the errors and damage that can occur with traditional cutting methods. Furthermore, the pin cutting laser machine avoids the potential for pin deformation or damage associated with traditional mechanical cutting, ensuring high quality and reliability of the coil pins after cutting.

[0017] Optionally, the frame is also provided with a clamping device for clamping the coil pins, and the clamping device includes a third lifting mechanism, an internal clamping mechanism and an external clamping mechanism. The third lifting mechanism is arranged on the frame, and the third lifting mechanism is used to simultaneously drive the internal clamping mechanism and the external clamping mechanism to lift and lower, the internal clamping mechanism is used to automatically clamp the pins inside the coil, and the external clamping mechanism is used to automatically clamp the pins outside the coil.

[0018] By adopting this technical solution, the clamping device uses a third lifting mechanism to stably and synchronously drive the inner and outer clamping mechanisms to raise and lower them, achieving precise clamping of the coil's internal and external pins. This ensures that the pins are securely fixed during laser cutting, effectively preventing the pins from falling during the cutting process, thereby improving the flatness of the cut surface.

[0019] Optionally, a shielding device is further included, which includes a support, a lifting drive and a cover plate, the support is fixed on the frame, the lifting drive is arranged on the support, and the lifting drive is used to drive the cover plate to rise and fall; the cover plate is located above the positioning fixture, and two through holes are provided on the cover plate, corresponding to the two pins of the coil respectively.

[0020] By adopting the above technical solution, in the subsequent processing, whether it is paint stripping, welding or pin cutting, the corresponding pins can be accurately acted on through these two through holes. At the same time, other waste chips generated during the processing can be prevented from falling onto the surface of the coil, ensuring the cleanliness of the coil surface.

[0021] Optionally, the unloading device includes a transport mechanism, a waste collection box and a unloading conveying mechanism, wherein the transport mechanism is used to transport qualified products to the unloading conveying mechanism, and the transport mechanism is used to transport unqualified products to the waste collection box.

[0022] By employing this technical solution, the handling mechanism accurately and rapidly identifies product status and transports qualified coil products that have passed rigorous testing to the unloading conveyor for subsequent packaging or storage. For unqualified products, the handling mechanism directly transfers them to the waste collection bin, enabling the timely recovery and disposal of defective products. This not only optimizes the production process and improves work efficiency, but also effectively avoids the confusion between qualified and unqualified products, ensuring strict control of product quality.

[0023] Optionally, the transport mechanism includes a support seat, a rotating mechanism, a fourth lifting mechanism and an adsorption mechanism, the support seat is arranged on the frame, the rotating mechanism is arranged on the support seat, the rotating mechanism is used to drive the fourth lifting mechanism to rotate, the fourth lifting mechanism is used to drive the adsorption mechanism to descend, and the adsorption mechanism is used to adsorb the coil after cutting.

[0024] By adopting the above technical solution, the transport mechanism combines multiple components such as the support base, the rotating mechanism, the fourth lifting mechanism and the adsorption mechanism to achieve precise grasping and transport of the coil after cutting. The rotating mechanism gives the transport mechanism flexible steering capabilities, allowing the adsorption mechanism to accurately align the coil position; the fourth lifting mechanism ensures that the adsorption mechanism can be smoothly lowered to the surface of the coil to achieve stable adsorption and grasping. It not only simplifies the cumbersome process of manual handling, but also greatly improves the accuracy and efficiency of handling. At the same time, the use of the adsorption mechanism avoids the problem of coil damage that may be caused by traditional mechanical clamping, ensuring the integrity and safety of the coil during the handling process.

[0025] Optionally, a molding process for a paint stripping and cutting integrated device using any of the above coils comprises the following steps:

[0026] Step 1: Place the inductor coil to be processed in the positioning fixture of the rotary feeding mechanism;

[0027] Step 2: Start the rotary feeding device to send the inductor coil to the paint stripping device for paint stripping;

[0028] Step 3: After the paint is removed, the rotary feeding mechanism continues to feed the inductor coil to the laser welding device for pin welding;

[0029] Step 4: After welding is completed, the rotary feeding mechanism sends the inductor coil to the pin cutting device for pin cutting;

[0030] Step 5: After cutting is completed, the transport mechanism of the automatic unloading system transports qualified or unqualified inductor coils to the unloading conveying mechanism or waste collection box according to the inspection results.

[0031] By adopting the above-mentioned technical solution, the integrated coil de-painting and cutting equipment and its molding process demonstrate the advantages of high automation and integration. The entire process begins with the precise placement of the inductor coil to be processed in the positioning fixture of the rotary feeder mechanism. Through the precise drive of the rotary feeder mechanism, the inductor coil undergoes paint stripping treatment by the paint stripping device, pin welding by the laser welding device, and pin cutting by the pin cutting device. Finally, the handling mechanism of the automatic unloading system intelligently separates qualified and unqualified products based on the inspection results. This series of operations not only achieves continuous and efficient coil processing, but also ensures the precise execution and quality control of each step. In particular, the collaborative work and intelligent coordination between the various components enable the entire molding process to improve production efficiency while also greatly ensuring product quality and consistency.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1.

This not only improves paint stripping efficiency but also ensures thoroughness and uniformity of the paint stripping effect, effectively avoiding the blind spots that may be left behind in traditional paint stripping methods.

[0034] 2. The rotary feeding device makes the entire production line layout more compact, reduces the floor space, and is conducive to space optimization in the workshop;

[0035] 3. Through the dual configuration of two laser welding devices, welding is performed on the external pins and the internal pins of the coil respectively. There is no need for the laser welding device to make additional horizontal movements, which greatly simplifies the operation process and improves overall efficiency.

[0050] The following is combined with Figure 1-12 This application is described in further detail.

[0051] The terms used in this application are for the purpose of describing specific embodiments only and are not intended to limit this application. Unless otherwise defined, technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs. The terms "first," "second," and similar terms used in this application do not indicate any order, quantity, or importance, but are simply used to distinguish different components.

[0052] The embodiment of the present application discloses a coil paint removal and cutting integrated device. Figure 1 and Figure 2The coil paint removal and cutting integrated equipment includes a frame 1, which includes a chassis 11 and a protective cover 12. The chassis 11 is provided with a rotary feeding device 2 and a visual inspection device 3, a paint stripping device 4, a laser welding device 5, a pin cutting device 6 and a blanking device 8 arranged in a circumferential order. The protective cover 12 is fixed to the top of the chassis 11, and the visual inspection device 3 is located in the middle of the multiple devices, wherein a loading area is provided between the visual inspection device 3 and the blanking device 8. All of the above devices are located inside the protective cover 12, and a loading trough 14 is provided on the side of the protective cover 12 close to the loading area to facilitate manual loading by staff. A blanking trough 15 is provided on the side adjacent to the protective cover 12. One end of the blanking device 8 is located inside the protective cover 12, and the other end extends out of the blanking trough 15 to facilitate automatic blanking.

[0053] Reference Figure 2 and Figure 3 The chassis 11 includes a panel 111 and a box body 112. A cavity is provided in the box body 112, and the panel 111 is fixed to the top of the box body 112. The rotary feeding device 2 includes a rotating disk 21, a rotating column 22 and a rotating drive mechanism 23. The top end of the rotating column 22 is fixedly connected to the lower surface of the rotating disk 21, and the bottom end of the rotating column 22 is rotatably connected to the frame 1. The rotating drive mechanism 23 is arranged on the lower surface of the panel 111. The rotating drive mechanism 23 is used to drive the rotating column 22 or the rotating disk 21 to rotate. The specific rotating drive mechanism 23 can be a motor or a motor gear mechanism. The rotating disk 21 is firmly connected to the frame 1 by the rotating column 22 fixed on its lower surface, which not only ensures that the rotating disk 21 can rotate smoothly under the action of the driving mechanism, but also maintains the rotating disk 21 at a suitable working height through the effective support of the rotating column 22. It meets the space requirements for coil operation of subsequent processing steps such as the visual inspection device 3, the paint stripping device 4, the laser welding device 5, the pin cutting device 6 and the blanking device 8, promotes smooth cooperation between the various devices, and thus improves the operating efficiency and processing accuracy of the entire coil paint stripping and cutting integrated equipment.

[0054] Reference Figure 2 and Figure 4 Multiple positioning jigs 24 are circumferentially arranged on the upper or lower surface of the rotating disk 21. Each positioning jig 24 has a circular, pancake-shaped positioning flange 241 integrally formed on its upper surface. A strip-shaped positioning slot 242 is defined in the middle of each positioning flange 241 for locating the internal pins of the coil. When the coil is fitted onto the positioning flange 241, the outer wall of the positioning flange 241 abuts the inner wall of the coil, and the internal pins of the coil are located within the positioning slot 242, thereby achieving precise positioning of the coil.

[0055] Reference Figure 4 and Figure 5, the side walls of the positioning jig 24 are provided with air holes 243, and the air holes 243 extend in the horizontal direction. An annular channel 244 is provided inside the positioning jig 24, one end of the air hole 243 is interconnected with the annular channel 244, and the other end of the air hole 243 is used to connect the air pipe and the vacuum equipment. At the same time, a plurality of adsorption holes 245 arranged at intervals along the circumference are provided on the upper surface of the positioning jig 24, each adsorption hole 245 is interconnected with the annular channel 244, and the positioning flange 241 is located in the middle of the plurality of adsorption holes 245. When the vacuum equipment is started and negative pressure is applied to the annular flow channel through the air pipe, the gas in the annular flow channel will be quickly extracted to form a local vacuum environment. This vacuum environment acts on the processed object through the adsorption through hole 94, generating a strong adsorption force, thereby achieving a firm clamping of the workpiece.

[0056] Reference Figure 2 and Figure 6 The visual inspection device 3 includes a base 31, a sliding seat 32, a leveling assembly 33, a camera assembly 34, and an illumination assembly 35. The base 31 is fixed to the upper surface of the frame 1, and the sliding seat 32 slides in conjunction with the base 31. The leveling assembly 33 is mounted on the sliding seat 32 and is used to adjust the position of the sliding seat 32 horizontally. The camera assembly 34 and the illumination assembly 35 are both mounted on the sliding seat 32, with the camera assembly 34 located directly above the illumination assembly 35. The heights of both are adjustable, and the illumination assembly 35 is provided with a first light-transmitting hole. As the turntable rotates the positioning jig 24, the positioning jig 24 passes directly under the illumination assembly 35. During the workflow, the turntable rotates steadily, carrying the positioning jig 24 to be inspected, passing directly under the directional illumination module. At this time, the illumination assembly 35 provides sufficient and uniform light, while the camera assembly 34 quickly captures detailed images of the positioning jig 24. The two work together to improve the accuracy and efficiency of inspection and ensure the rigor of product quality control.

[0057] Reference Figure 2 and Figure 3, the rotating disk 21 is provided with a plurality of avoidance grooves 211 along the circumference, and the avoidance grooves 211 correspond one-to-one to the positioning jig 24, and the avoidance grooves 211 are located above or below the positioning jig 24. In this embodiment, since the positioning jig 24 is located above the rotating disk 21, the avoidance grooves 211 are located below the positioning jig 24. The rotary feeding device 2 realizes high automation and space optimization of the coil processing process through the coordinated action of the rotating disk 21 and the rotary drive mechanism 23. A plurality of positioning jigs 24 are provided on the rotating disk 21, and each positioning jig 24 is equipped with a positioning flange 241 for accurately positioning the coil, thereby ensuring the stability and accuracy of the coil during the processing. At the same time, avoidance grooves 211 corresponding to the positioning jigs 24 are also provided on the rotating disk 21. These avoidance grooves 211 are located above or below the positioning jigs 24, providing necessary operating space for key processes such as the paint stripping device 4, the laser welding device 5 and the pin cutting device 6, avoiding mutual interference between the equipment, and further improving the compactness of the equipment and the smoothness of operation.

[0058] Reference Figure 2 、 Figure 7 and Figure 8 The paint stripping device 4 includes an upper paint stripping mechanism 41 and a lower paint stripping mechanism 42. The upper paint stripping mechanism 41 and the lower paint stripping mechanism 42 operate synchronously to perform efficient and comprehensive laser paint stripping on the top and bottom of the coil pins respectively, which not only improves the paint stripping efficiency, but also ensures the thoroughness and uniformity of the paint stripping effect, and effectively avoids the blind spot problem that may be left in the traditional paint stripping method.

[0059] Reference Figure 7 The upper paint stripping mechanism 41 includes a first lifting assembly 411 and a first paint stripping laser machine 412. The first lifting assembly 411 includes a first support base 4111, a first screw rod 4112, and a first motor 4113. The first support base 4111 is fixed to the upper surface of the top of the frame 1. The first screw rod 4112 extends vertically, and both ends of the first screw rod 4112 are rotatably connected to the first support base 4111. The first motor 4113 is mounted on the top of the first support base 4111, and the output shaft of the first motor 4113 is fixedly connected to the top of the first screw rod 4112. The first lifting assembly 411 can automatically adjust the height of the first paint stripping laser machine 412, which is used to strip paint from the top of the coil pins.

[0060] Reference Figure 8The lower paint stripping mechanism 42 includes a second lifting assembly 421 and a second paint stripping laser machine 422. The second lifting assembly 421 includes a second support base 4211, a second screw rod 4212, and a second motor 4213. The second support base 4211 is fixed to the bottom of the box 112. The second screw rod 4212 extends vertically and is rotatably connected to the second support base 4211 at both ends. The second motor 4213 is fixed to the top of the second support base 4211, and the output shaft of the second motor 4213 is fixedly connected to the top of the second screw rod 4212. The second paint stripping laser machine 422 is used to strip paint from the bottom of the coil pins. This not only improves paint stripping efficiency but also ensures thoroughness and uniformity of the paint stripping effect.

[0061] Reference Figure 2 and Figure 9 To ensure that the lower paint stripping mechanism 42 can strip paint from beneath the coil pins, a first light-transmitting hole 13 is formed through the panel 111, located directly above the lower paint stripping mechanism 42. A dust-proof mechanism 16 is also fixed to the lower surface of the panel 111. In this embodiment, the dust-proof mechanism 16 comprises a dust box 161 fixed to the lower surface of the panel 111. The dust box 161 has a second light-transmitting hole formed therein and a transparent glass 162 fixed thereon to block the second light-transmitting hole. When the coil pins rotate with the rotating disk 21 to the position directly below the lower paint stripping mechanism 42, the second paint-stripping laser 422 is activated to strip paint from the bottom of the coil pins. Dust and waste generated during the paint stripping process naturally fall by gravity into the dust box 161 below. Effective collection by the dust box 161 prevents contamination of the working environment by paint-stripping waste, maintaining a clean and efficient operation of the equipment. The provision of the transparent glass 162 not only prevents the leakage of paint stripping waste, but also facilitates real-time monitoring of the dust collection status, providing convenience for the maintenance and care of the equipment.

[0062] Reference Figure 2There are two laser welding devices 5. The first laser welding device 5 is used to weld the pins outside the coil, and the second laser welding device 5 is used to weld the pins inside the coil. When the coil rotates with the rotating disk 21 to the first laser welding device 5, the first laser welding device 5 starts and accurately welds the pins outside the coil. Subsequently, the coil continues to rotate, and when it reaches the second laser welding device 5, the second laser welding device 5 welds the pins inside the coil. Of course, the first laser welding device 5 can also be used to weld the pins inside the coil, and in this case, the second laser welding device 5 welds the pins outside the coil. This process does not require the laser welding device 5 to make additional movements in the horizontal direction, which greatly simplifies the operation process and improves overall efficiency. At the same time, since the welding operations are completed sequentially during the rotation of the coil, a high degree of automation of the coil processing process is also achieved, further improving production efficiency.

[0063] Reference Figure 10 Each laser welding device 5 includes a transverse movement mechanism 51, a longitudinal movement mechanism 52, a first lifting mechanism 53, a pin clamping mechanism 54, and a soldering mechanism 55. The transverse movement mechanism 51 is mounted on the frame 1 and drives the longitudinal movement mechanism 52 horizontally. The longitudinal movement mechanism 52 drives the first lifting mechanism 53 in mutually perpendicular horizontal directions. The first lifting mechanism 53 drives the pin clamping mechanism 54 and the soldering mechanism 55 upward and downward. The pin clamping mechanism 54 is used to clamp the coil pins, and the soldering mechanism 55 is used to solder the coil pins. Specifically, the transverse movement mechanism 51, the longitudinal movement mechanism 52, and the first lifting mechanism 53 can be motor screw structures, cylinders, or linear motors. The pin clamping mechanism 54 can be a claw cylinder. The dual configuration of the first and second laser welding devices 5, respectively, welds the coil pins on the outside and inside. This not only meets the welding requirements of complex coil structures, but also reduces the horizontal displacement of the first and second laser welding devices 5, further improving welding efficiency. The pin clamping mechanism 54 accurately clamps the pins, and the soldering mechanism 55 performs welding operations quickly and accurately. The two work together to greatly improve the welding quality and efficiency.

[0064] Continue to refer to Figure 10The soldering mechanism 55 includes a universal adjustment assembly 551 and a solder pen 552. The universal adjustment assembly 551 is mounted on one side of the pin clamping mechanism 54, and the solder pen 552 is mounted on the universal adjustment assembly 551. The universal adjustment assembly 551 includes multiple adjustment members, each of which can slide or rotate relative to the other. The solder pen 552 is mounted on the universal adjustment assembly 551, which includes multiple adjustment members, each of which can slide or rotate relative to the other. This allows the solder pen 552 to be freely adjusted in all directions within three dimensions, ensuring high quality and consistency in the soldering process.

[0065] Reference Figure 2 The pin cutting device 6 includes a second lifting mechanism 62 and a pin cutting laser machine 63. The second lifting mechanism 62 is arranged on the upper surface of the frame 1. The second lifting mechanism 62 is used to drive the pin cutting laser machine 63 to rise and fall, and the pin cutting laser machine 63 is used to cut off the pins after soldering. The specific second lifting mechanism 62 can be a motor screw mechanism or a cylinder. After the coil completes the pin welding through the laser welding device 5, the rotating disk 21 will continue to drive it to rotate to the pin cutting device 6. At this time, the second lifting mechanism 62 starts and drives the pin cutting laser machine 63 to descend to an appropriate height so that it can accurately align with the pins after soldering. Subsequently, the pin cutting laser machine 63 emits a high-intensity laser beam to quickly and accurately cut off the pins. This process not only ensures the accuracy and consistency of pin cutting, but also effectively avoids errors and damage that may occur in traditional cutting methods.

[0066] Reference Figure 2 and Figure 11 , the upper surface of the panel 111 is also provided with a clamping device 7 for clamping the two pins of the coil, and the clamping device 7 is located below the rotating disk 21. Specifically, the clamping device 7 includes a third lifting mechanism 71, an internal clamping mechanism 72 and an external clamping mechanism 73. The third lifting mechanism 71 is provided on the frame 1. The third lifting mechanism 71 is used to simultaneously drive the internal clamping mechanism 72 and the external clamping mechanism 73 to rise and fall. The internal clamping mechanism 72 is used to automatically clamp the pins inside the coil, and the external clamping mechanism 73 is used to automatically clamp the pins outside the coil. The clamping device 7 stably and synchronously drives the internal clamping mechanism 72 and the external clamping mechanism 73 to rise and fall through the third lifting mechanism 71, thereby achieving precise clamping of the internal and external pins of the coil. It ensures that the pins can be firmly fixed during the laser cutting operation, and the laser cutting method effectively avoids the falling phenomenon of the pins during the cutting process, thereby improving the flatness of the cutting surface. The third lifting mechanism 71 may be a cylinder or a motor screw structure, and the inner clamping mechanism 72 and the outer clamping mechanism 73 may both include a clamping claw cylinder and a clamping member.

[0067] Reference Figure 4 and Figure 11The positioning jig 24 is provided with a first through-hole 246 and a second through-hole 247. The first through-hole 246 is used for the inner clamping mechanism 72 to pass through the positioning jig 24, thereby clamping the pins inside the coil; the second through-hole 247 is used for the outer clamping mechanism 73 to pass through the positioning jig 24, thereby clamping the pins outside the coil, ensuring the smooth progress of the clamping action.

[0068] Reference Figure 2 and Figure 12 At the same time, a plurality of shielding devices 9 are also provided on the upper surface of the panel 111. Each shielding device 9 includes a support 91, a lifting drive 92 and a cover 93. The support 91 is fixed to the top of the panel 111, and the lifting drive 92 is provided on the support 91. The lifting drive 92 is used to drive the cover 93 to move up and down. The cover 93 is located above the positioning jig 24, and two through holes 94 are provided on the cover 93. When the coil is placed inside the positioning jig 24, one of the through holes 94 will be located just above the internal pin of the coil, while the other through hole 94 will be located above the external pin. In the subsequent processing, whether it is paint stripping, welding or pin cutting, the corresponding pins can be accurately acted on through these two through holes. At the same time, it can also prevent other waste chips generated during the processing from falling on the surface of the coil, thereby ensuring the cleanliness of the coil surface.

[0069] Continue to refer to Figure 2 and Figure 12 , these shielding devices 9 play different roles in different processing stages. For example, one of the shielding devices 9 will cooperate with the paint stripping device 4 to ensure that the paint stripping process is only carried out on the pins that need to be stripped, avoiding unnecessary damage to other parts. At the same time, there are two shielding devices 9 that work with two laser welding devices 5 respectively, which can ensure the accuracy and stability of the welding process. There is also a shielding device 9 that is specifically used to cooperate with the pin cutting device 6 to achieve precise cutting of the pins. It is worth mentioning that the inner diameter or minimum spacing of each through hole 94 is designed to be larger than the diameter of the pin. The advantage of this is that even if the pins move or deform slightly during the processing process, they can ensure that they can pass through the through hole smoothly without any hindrance. In addition, the edges of the through holes 94 are also chamfered. This design not only improves the aesthetics, but more importantly, it can reduce the friction between the pins and the edges of the through holes to a certain extent, thereby extending the service life of the equipment.

[0070] Reference Figure 2 and Figure 12The unloading device 8 comprises a handling mechanism 81, a waste collection bin 82, and a unloading conveyor mechanism 83. The handling mechanism 81 is used to transport qualified products to the unloading conveyor mechanism 83, while the handling mechanism 82 is used to transport unqualified products to the waste collection bin 82. The handling mechanism 81 accurately and quickly identifies product status and transports qualified coil products that have passed rigorous testing to the unloading conveyor mechanism 83 for subsequent packaging or storage. Unqualified products are directly transferred to the waste collection bin 82 by the handling mechanism 81, ensuring the timely recovery and disposal of defective products. This not only optimizes the production process and improves work efficiency, but also effectively avoids the confusion between qualified and unqualified products, ensuring strict control of product quality.

[0071] Reference Figure 12 The transport mechanism 81 includes a support base 811, a rotating mechanism 812, a fourth lifting mechanism 813 and an adsorption mechanism 814. The support base 811 is set on the frame 1, and the rotating mechanism 812 is set on the support base 811. The rotating mechanism 812 is used to drive the fourth lifting mechanism 813 to rotate, and the fourth lifting mechanism 813 is used to drive the adsorption mechanism 814 to descend. The adsorption mechanism 814 is used to adsorb the coil after cutting. The rotating mechanism 812 gives the transport mechanism 81 a flexible steering ability, so that the adsorption mechanism 814 can accurately align with the coil position; the fourth lifting mechanism 813 ensures that the adsorption mechanism 814 can smoothly descend to the coil surface to achieve stable adsorption and grasping. It not only simplifies the tedious process of manual handling, but also greatly improves the accuracy and efficiency of handling.

[0072] The operating principle of the above embodiment is as follows: The equipment's workflow begins with a rotary feeder 2, which feeds the coils to be processed individually into subsequent processing steps. Next, the coils pass through a visual inspection device 3, which utilizes advanced image recognition technology to accurately detect the coils' position, size, and surface condition, ensuring accuracy and consistency in subsequent processing. The coils then enter a paint stripping device 4. In this step, the paint stripping device 4 uses a specific chemical solution or physical method to quickly and effectively remove the insulating paint layer from the coils' surfaces, preparing them for subsequent connection and welding operations. Next, the coils enter a laser welding device 5, which automatically welds the coils to leads or other electronic components, completing the circuit connection. The automation of this step significantly improves welding accuracy and efficiency, reducing the risk of manual errors. Afterward, a lead trimming device 6 trims the welded coils, removing excess leads according to pre-set specifications and dimensions to ensure the coils meet final dimensional requirements. Finally, the processed coils are fed into a blanking device 8 for collection and sorting. The entire processing process is smooth and efficient, which greatly shortens the coil processing cycle and improves production efficiency.

[0073] Example 2

[0074] This embodiment discloses a molding process using the paint stripping and cutting integrated device in embodiment 1, comprising the following steps:

[0075] Step 1: Place the inductor coil to be processed in the positioning fixture of the rotary feeding mechanism;

[0076] Step 2: Start the rotary feeding device 2 to send the inductor coil to the visual inspection device 3 for visual inspection;

[0077] Step 3: The rotating feeding device 2 sends the inductor coil to the paint stripping device 4 for paint stripping;

[0078] Step 4: After the paint is removed, the rotary feeding device 2 continues to feed the inductor coil to the two laser welding devices 5 in sequence to weld the two pins of the coil respectively;

[0079] Step 5: After welding is completed, the inductor coil is first sent to the pin cutting device 6, and the two pins of the coil are first clamped and fixed by the clamping device 7;

[0080] Step 6: Using the pin cutting device 6 to cut the two pins at the same time;

[0081] Step 7: After the cutting is completed, the transport mechanism 81 of the automatic unloading system transports the qualified or unqualified inductor coils to the unloading conveying mechanism 83 or the waste collection box 82 according to the detection results.

[0082] The coil stripping and cutting equipment and its forming process utilize a highly integrated automated control system, achieving fully automated processing from initial inductor coil positioning to final distribution. Its core lies in the precise coordination and collaboration of a rotary feeder mechanism, a visual inspection device 3, a paint stripping device 4, a laser welding device 5, a lead cutting device 6, and an automatic unloading system. The rotary feeder, the heart of the entire process, ensures the stable and orderly transfer of the inductor coils between the various processing units through its precise drive mechanism, eliminating the errors and inefficiencies that can occur with traditional manual operations. During visual inspection, a high-precision camera combined with an intelligent recognition algorithm quickly and accurately captures the position, shape, and potential defects of the inductor coils, providing reliable data support for subsequent processing. The paint stripping device 4 utilizes advanced physical or chemical methods to efficiently and gently remove the paint layer from the coil surface, preparing it for welding. The laser welding device 5 precisely controls welding parameters to ensure a secure connection between the leads and the coil body while preventing issues such as overheating and poor welding.

[0083] The lead cutting device 6 utilizes the synchronous rotation of the rotary feed mechanism, coupled with a precise cutting tool, to achieve simultaneous cutting of the two leads, improving cutting efficiency while ensuring a smooth and consistent cut surface. Finally, the automatic unloading system intelligently separates qualified and unqualified products into separate unloading and conveying mechanisms 83 or waste collection bins 82 based on the results of visual inspection, ensuring strict control of product quality and efficient resource utilization.

[0084] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
