[0007] By adopting the above technical solution, the coil is first driven to move precisely in the circumferential direction by a rotary feeding device, and then the first paint stripping laser machine of the upper paint stripping mechanism and the second paint stripping laser machine of the lower paint stripping mechanism work synchronously to perform efficient and comprehensive laser paint stripping on the top and bottom of the coil pins, respectively. This 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. At the same time, the equipment also integrates welding and pin cutting functions, and automatically completes unloading after processing. The entire process has a compact structure and smooth operation, which greatly improves production efficiency and operational flexibility, and brings revolutionary improvements to the coil processing industry. This equipment is not only compact in structure and smooth in operation, but also greatly improves production efficiency and flexibility.

[0008] Optionally, the rotary feeding device includes a rotating disk, a rotating column and a rotating drive mechanism, the top end 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 circumferentially arranged 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, the avoidance grooves correspond one-to-one to the positioning jigs, and the avoidance grooves are located above or below the positioning jigs.

[0009] By adopting the above technical solution, the rotating disk relies on the stable rotation connection between the rotating column fixed on its lower surface and the frame, which not only ensures that the rotating disk can rotate smoothly under the action of the driving mechanism, but also maintains a suitable working height through the effective support of the rotating column to meet the space requirements of the subsequent processing procedures such as the visual inspection device, paint stripping device, laser welding device, pin cutting device and unloading device for coil operation, promotes smooth cooperation 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, avoidance grooves corresponding to the positioning fixtures are also set on the rotating disk. These avoidance grooves are located above or below the positioning fixtures, providing necessary operating space for key processes such as the paint stripping device, laser welding device and pin cutting device, avoiding mutual interference between equipment, and further improving the compactness of the equipment and the smoothness of operation.

[0010] 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.

[0011] By adopting the above technical solution, the laser welding device adopts a highly flexible and precise multi-axis moving mechanism to achieve efficient and accurate coil pin welding. The horizontal moving mechanism, the longitudinal moving mechanism and the first lifting mechanism are combined to build a three-dimensional mobile platform, which can accurately adjust the relative position between the coil pin and the soldering mechanism in all directions and angles. Through the dual configuration of two laser welding devices, the pins outside the coil and the pins inside the coil are welded respectively. When the coil rotates with the rotating disk to the first laser welding device, the first laser welding device is started to accurately weld the pins outside the coil. Subsequently, the coil continues to rotate, and when it reaches the second laser welding device, the second laser welding device welds the pins inside the coil. This process does not require the laser welding device to make additional movements in the horizontal direction, which greatly simplifies the operation process and improves the overall efficiency. At the same time, since the welding operation is completed sequentially during the rotation of the coil, the coil processing process is highly automated, further improving production efficiency.

[0013] By adopting the above technical solution, the solder pen is installed on the universal adjustment component, which includes multiple adjustment parts. Two adjacent adjustment parts can slide and rotate relative to each other, thus giving the solder pen the ability to adjust freely in all directions in three-dimensional space. Not only can the solder pen accurately touch every tiny part on the coil pin, but it can also easily handle complex and changeable coil structures, ensuring the high quality and consistency of the welding operation. At the same time, it also simplifies the operation complexity during the welding process and improves work efficiency.

[0015] By adopting the above technical solution, after the coil has completed pin welding through the laser welding device, the rotating disk will continue to drive it to rotate to the pin cutting device. At this time, the second lifting mechanism is started to drive the pin cutting laser machine to descend to an appropriate height so that it can accurately align the pins after soldering. Subsequently, the pin cutting laser machine 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 the errors and damage that may occur in traditional cutting methods. At the same time, the pin cutting laser machine also avoids the problems of pin deformation or damage that may be caused by traditional mechanical cutting, ensuring the good quality and reliability of the coil pins after cutting.

[0017] By adopting the above technical solution, the clamping device drives the inner clamping mechanism and the outer clamping mechanism to rise and fall stably and synchronously through the third lifting mechanism, thus realizing the precise clamping of the inner and outer pins of the coil. This ensures that the pins can be firmly fixed during the laser cutting operation, and the laser cutting method effectively avoids the pins from falling during the cutting process, thereby improving the flatness of the cutting surface.

[0018] Optionally, a shielding device is also 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, which correspond to the two pins of the coil respectively.

[0019] 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 the two through holes.

It not only optimizes the production process and improves work efficiency, but also effectively avoids the confusion of qualified and unqualified products, ensuring strict control of product quality.

[0022] 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.

[0023] By adopting the above technical solution, the handling mechanism combines multiple components such as the support base, the rotating mechanism, the fourth lifting mechanism and the adsorption mechanism to achieve accurate grasping and handling of the coil after cutting. The rotating mechanism gives the handling mechanism flexible steering capabilities, allowing the adsorption mechanism to accurately align the coil position; the fourth lifting mechanism ensures that the adsorption mechanism can smoothly descend 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 application 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.

[0024] Optionally, a molding process of a paint removal and cutting integrated device using any of the above coils comprises the following steps: Step 1: Place the inductor coil to be processed in the positioning fixture of the rotating feeding mechanism; Step 2: Start the rotary feeding device to send the inductor coil to the paint stripping device for paint stripping; Step 3: After the paint removal is completed, the rotary feeding mechanism continues to feed the inductor coil to the laser welding device for pin welding; Step 4: After welding is completed, the rotating feeding mechanism sends the inductor coil to the pin cutting device for pin cutting; Step 5: After the cutting is completed, the transport mechanism of the automatic unloading system transports the qualified or unqualified inductor coils to the unloading conveying mechanism or the waste collection box according to the detection results.

[0025] By adopting the above technical solutions, the coil depainting and cutting integrated equipment and its molding process show the advantages of high automation and integration. The whole process starts with the precise placement of the inductor coil to be processed in the positioning fixture of the rotary feeding mechanism. Through the precise drive of the rotary feeding mechanism, the inductor coil is successively subjected to the paint stripping treatment of the paint stripping device, the pin welding of the laser welding device, and the pin cutting of the pin cutting device, until finally the handling mechanism of the automatic unloading system performs intelligent diversion of qualified and unqualified products according to the test results. This series of operations not only realizes the continuity and efficiency of 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 greatly guarantee the quality and consistency of the product while improving production efficiency.

A feeding trough 15 is provided on the side adjacent to the protective cover 12, and one end of the feeding device 8 is located in the protective cover 12, and the other end extends out of the feeding trough 15, which is convenient for automatic feeding.

[0043] 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. 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 of the rotating column 22 is fixedly connected to the lower surface of the rotating disk 21. 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 connected to the frame 1 by the stable rotation of 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 visual inspection device 3, paint stripping device 4, laser welding device 5, pin cutting device 6 and unloading device 8, promotes smooth cooperation between various devices, and thus improves the operating efficiency and processing accuracy of the entire coil paint stripping and cutting integrated equipment.

[0044] Reference Figure 2 and Figure 4 A plurality of positioning jigs 24 are arranged along the circumferential direction on the upper or lower surface of the rotating disk 21. A circular pancake-shaped positioning flange 241 is integrally formed on the upper surface of each positioning jig 24. A positioning groove 242 for positioning the internal pins of the coil is provided in the middle of the positioning flange 241. The positioning groove 242 is in the shape of a strip. When the coil is sleeved on the positioning flange 241, the outer wall of the positioning flange 241 abuts against the inner wall of the coil, and the internal pins of the coil are located in the positioning groove 242, thereby realizing accurate positioning of the coil.

The heights of both can be adjusted. A first light-transmitting hole is opened on the lighting component 35. When the turntable drives the positioning fixture 24 to rotate, the positioning fixture 24 will pass directly under the lighting component 35. In the work process, the turntable rotates steadily, carrying the positioning fixture 24 to be inspected and passing directly under the directional lighting module in turn.

A plurality of positioning jigs 24 are arranged 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 fixtures 24 are also opened on the rotating disk 21. These avoidance grooves 211 are located above or below the positioning fixtures 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.

[0048] 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 treatment 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.

When the coil pin rotates with the rotating disk 21 to the lower part of the lower paint stripping mechanism 42, the second paint stripping laser machine 422 is started to strip the paint on the bottom of the coil pin. The dust and waste generated during the paint stripping process naturally fall into the dust box 161 below under the action of gravity. Through the effective collection of the dust box 161, the pollution of the working environment by the paint stripping waste is avoided, and the cleanliness and efficient operation of the equipment are maintained. 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.

Of course, the first laser welding device 5 can also be used to weld the pins inside the coil, and 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 the overall efficiency.

The specific lateral moving mechanism 51, the longitudinal moving mechanism 52, the first lifting mechanism 53, etc. can be a motor screw structure, or a cylinder or a linear motor, etc., and the specific pin clamping mechanism 54 can be a clamping claw cylinder. The dual configuration of the first laser welding device 5 and the second laser welding device 5 respectively welds the pins outside the coil and the pins inside the coil, which not only meets the welding requirements of the complex coil structure, but also reduces the displacement of the first laser welding device 5 and the second laser welding device 5 in the horizontal direction, further improving the 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.

[0054] Continue to refer to Fig.10The soldering mechanism 55 includes a universal adjustment component 551 and a solder pen 552. The universal adjustment component 551 is arranged on one side of the pin clamping mechanism 54. The solder pen 552 is arranged on the universal adjustment component 551. The universal adjustment component 551 includes a plurality of adjustment parts. Two adjacent adjustment parts can slide or rotate relative to each other. The solder pen 552 is installed on the universal adjustment component 551. The universal adjustment component 551 includes a plurality of adjustment parts. Adjacent adjustment parts can slide and rotate relative to each other, thereby giving the solder pen 552 the ability to freely adjust in all directions in three-dimensional space, ensuring the high quality and consistency of the welding operation.

[0055] 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. 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 is pin-welded by 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 is started to drive 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.

[0056] Reference Figure 2 and Fig.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 inner clamping mechanism 72 and an outer clamping mechanism 73. The third lifting mechanism 71 is arranged on the frame 1. The third lifting mechanism 71 is used to simultaneously drive the inner clamping mechanism 72 and the outer clamping mechanism 73 to rise and fall. The inner clamping mechanism 72 is used to automatically clamp the pins inside the coil, and the outer clamping mechanism 73 is used to automatically clamp the pins outside the coil. The clamping device 7 stably and synchronously drives the inner clamping mechanism 72 and the outer clamping mechanism 73 to rise and fall through the third lifting mechanism 71, thereby realizing the precise clamping of the inner and outer 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.

[0057] Reference Figure 4 and Fig.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.

[0058] Reference Figure 2 and Fig.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 plate 93, the support 91 is fixed to the top of the panel 111, the lifting drive 92 is arranged on the support 91, and the lifting drive 92 is used to drive the cover plate 93 to rise and fall. The cover plate 93 is located above the positioning fixture 24, and two through holes 94 are provided on the cover plate 93. When the coil is placed inside the positioning fixture 24, one of the through holes 94 will be located just above the internal pin of the coil, and 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, and at the same time, some other waste chips generated during the processing can be prevented from falling on the surface of the coil, thereby ensuring the cleanliness of the coil surface.

[0059] Continue to refer to Figure 2 and Fig.12 , these shielding devices 9 play different roles in different processing stages. For example, one of the shielding devices 9 will work 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 during the welding process. There is also a shielding device 9 that is specifically used to work 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 holes smoothly without any hindrance. In addition, chamfers are also set on the edges of the through holes 94. 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.

[0060] Reference Figure 2 and Fig.12The unloading device 8 includes a transport mechanism 81, a waste collection box 82 and an unloading conveying mechanism 83. The transport mechanism 81 is used to transport qualified products to the unloading conveying mechanism 83, and the transport mechanism 81 is used to transport unqualified products to the waste collection box 82. The transport mechanism 81 accurately and quickly identifies the product status, and transports the qualified coil products after strict inspection to the unloading conveying mechanism 83 for subsequent packaging or warehousing operations; and for unqualified products, the transport mechanism 81 directly transfers them to the waste collection box 82, realizing the timely recovery and treatment of defective products. It 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.

[0061] Reference Fig.12 The transport mechanism 81 includes a support seat 811, a rotating mechanism 812, a fourth lifting mechanism 813 and an adsorption mechanism 814. The support seat 811 is arranged on the frame 1, and the rotating mechanism 812 is arranged on the support seat 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, and 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 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 cumbersome process of manual handling, but also greatly improves the accuracy and efficiency of handling.

[0062] The implementation principle of the above embodiment is as follows: the working process of the equipment starts from the rotating feeding device 2, which is responsible for feeding the coils to be processed one by one into the subsequent processing steps. Next, the coil will pass through the visual inspection device 3, which uses advanced image recognition technology to accurately detect the position, size and surface state of the coil to ensure the accuracy and consistency of subsequent processing. Then, the coil enters the paint stripping device 4. In this step, the paint stripping device 4 will use a specific chemical solution or physical method to quickly and effectively remove the insulating paint layer on the surface of the coil to prepare for subsequent connection and welding operations. Next, the coil is fed into the laser welding device 5. Here, the laser welding device 5 will automatically weld the coil with the pin or other electronic components to complete the circuit connection. The automated processing of this step greatly improves the accuracy and efficiency of welding and reduces the error rate of manual operation. Afterwards, the pin cutting device 6 will cut the pins of the welded coils, and cut off the excess pins according to the preset specifications and sizes to make the coils meet the final size requirements. Finally, the processed coils are fed into the unloading device 8 for collection and classification. The entire processing process is smooth and efficient, which greatly shortens the coil processing cycle and improves production efficiency.

[0063] Example 2 This embodiment discloses a molding process using the paint removal and cutting integrated device in Embodiment 1, comprising the following steps: Step 1: Place the inductor coil to be processed in the positioning fixture of the rotating feeding mechanism; Step 2: Start the rotary feeding device 2 to send the inductor coil to the visual inspection device 3 for visual inspection; Step 3: The rotating feeding device 2 sends the inductor coil to the paint stripping device 4 for paint stripping; Step 4: After the paint removal is completed, the rotating feeding device 2 continues to feed the inductor coil to two laser welding devices 5 in sequence to weld the two pins of the coil respectively; 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; Step 6: Using the pin cutting device 6 to cut two pins at the same time; 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.

[0064] The paint stripping and cutting integrated equipment and its forming process for the coil are based on a highly integrated automatic control system, realizing the full automation process from the initial positioning of the inductor coil to the final diversion. Its core lies in the precise coordination and collaborative operation of the rotary feeding mechanism, the visual inspection device 3, the paint stripping device 4, the laser welding device 5, the pin cutting device 6 and the automatic unloading system. As the heart of the entire process, the rotary feeding mechanism ensures that the inductor coil can be stably and orderly transferred between the various processing units through its precise driving mechanism, avoiding the errors and inefficiencies that may occur in traditional manual operations. In the visual inspection link, the combination of high-precision cameras and intelligent recognition algorithms can quickly and accurately capture the position, shape and possible defects of the inductor coil, providing reliable data support for subsequent processing. The paint stripping device 4 uses advanced physical or chemical methods to efficiently and gently remove the paint layer on the surface of the coil to prepare for welding operations. The laser welding device 5 ensures the firm connection between the pin and the coil body by precisely controlling the welding parameters, while avoiding problems such as overheating or poor welding.

[0065] The pin cutting device 6 utilizes the synchronous rotation of the rotary feeding mechanism and cooperates with the precise cutting tool to achieve the synchronous cutting of the two pins, which not only improves the cutting efficiency, but also ensures the flatness and consistency of the cutting surface. Finally, the automatic unloading system intelligently divides qualified products and unqualified products into different unloading conveying mechanisms 83 or waste collection boxes 82 according to the results of visual inspection, achieving strict control of product quality and effective use of resources.

Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
