[0002] The magnetic component is a fitting installed in a miniature circuit breaker. As Figure 1 shown, it generally includes a static contact a, a wiring board b and a coil c. The coil c includes a spiral main body and pins respectively located on the left and right sides of the spiral main body. The wiring board b is attached below the pin on the left side of the coil c, and the pin is fixed to the wiring board b by welding. The static contact a is attached below the pin at the right end of the coil c and is fixed to the pin by welding. The static contact a is divided into two parts, including a first sheet body and a second sheet body. Before welding the magnetic component, it is necessary to first rivet the first sheet body and the second sheet body to make them into one body, and then weld it to the coil. In the prior art, the welding of the coil to the wiring board and the static contact is all carried out manually. A soldering flux sheet is inserted between the wiring board and the coil pin and between the static contact and the coil pin, and then welded by a soldering gun. The welding efficiency is low, the welding effect is poor, and it is easy to cause uneven solder joints. Summary of the Invention

Along the circumferential direction of the turntable, a plurality of welding jigs are provided. The welding jig is provided with a coil placement groove, a wiring board placement groove and a static contact placement groove. The wiring board feeding station is provided with a wiring board feeding channel and a wiring board clamping member for clamping the wiring board into the wiring board placement groove. The static contact feeding station is provided with a static contact feeding channel and a static contact clamping member for clamping the static contact into the static contact placement groove. The coil feeding station is provided with a coil feeding channel and a coil clamping member for clamping the coil into the coil placement groove. The welding station is provided with a feeding mechanism, a first welding mechanism and a second welding mechanism. The first welding mechanism and the feeding mechanism are relatively arranged on the upper and lower sides of the welding jig, and the second welding mechanism is located outside the welding jig. The discharging station is provided with a discharging channel and a discharging clamping member for clamping the welded magnetic component onto the discharging channel.

[0005] By adopting the above technical solution, full-automatic assembly and welding are realized, with high processing efficiency, good product quality and high qualification rate. The wiring board, static contact and coil are automatically fed through the feeding channel respectively, and the clamping part moves between the feeding channel and the welding fixture to place each material in the corresponding receiving groove. Then, the welding mechanism welds between the coil and the wiring board and between the coil and the static contact. After welding, the assembled and welded magnetic component is unloaded through the unloading station.

[0006] A further setting of the present utility model: The welding fixture includes a base, a sliding seat, a coil placement rack, a wiring board placement seat and a static contact placement seat. The coil placement rack is provided with the coil placement groove, the wiring board placement seat is provided with the wiring board placement groove, and the static contact placement seat is provided with the static contact placement groove. The wiring board placement groove and the static contact placement groove are located on both sides of the coil placement groove. The sliding seat is slidably arranged on the base. A first push rod and a second push rod are slidably arranged on the sliding seat. The coil placement rack synchronously slides with the first push rod. One of the wiring board placement seat and the static contact placement seat is arranged on the second push rod, and the other is arranged on the sliding seat or on a third push rod slidably arranged on the sliding seat. It further includes a positioning member. The positioning member is hinged to the coil placement rack. The upper end of the positioning member is provided with a pressing arm. A positioning member return spring is arranged between the lower end of the positioning member and the coil placement rack. The upper end of the positioning member is reset towards the coil placement rack under the action of the positioning member return spring to form the positioning of the coil by the pressing arm and the coil placement groove.

[0007] By adopting the above further setting, a driving member is additionally arranged outside the positioning member at the coil feeding station. The positioning member rotates relative to the coil placement rack under the action of the driving member, exposing or partially covering the coil placement groove. When the pressing arm moves forward, it is convenient to place the coil into or take out the coil from the coil placement groove. When the pressing arm moves backward, it can press the coil in the coil placement groove to fix it in the coil placement groove and prevent the coil from moving, affecting the welding effect. The positioning member return spring can quickly realize the reset of the positioning member. Accommodation cavities are arranged on both the lower end of the positioning member and the coil placement rack, and both ends of the positioning member return spring are located in the corresponding accommodation cavities, making the return spring structure stable. At the same time, a driving mechanism is additionally arranged at the rear end of the push rod. The push rod is pushed forward by the driving mechanism. When the first push rod moves forward, there is a gap between the coil, the wiring board and the static contact, which is convenient for the welding sheet to be inserted. If the welding sheet is inserted between the coil and the wiring board, the coil and the wiring board are welded first, and then the second push rod and the first push rod are pushed to slide forward synchronously, so that the coil and the wiring board slide forward synchronously. There is a gap between the coil and the static contact, which is convenient for the welding sheet to be inserted, and then the coil and the static contact are welded. On the contrary, the coil and the static contact are welded first, and then the coil and the wiring board are welded.

[0008] Further setting of the present utility model: The feeding mechanism includes a mounting frame and a feeding tray arranged on the mounting frame. A conveying assembly for conveying the welding rod towards the first welding mechanism is arranged on the mounting frame. The conveying assembly includes a first clamping member, a second clamping member for clamping the welding rod, a second driving member for driving the two clamping members to synchronously lift and lower in the vertical direction, a third driving member for driving the second clamping member to lift and lower independently in the vertical direction, a fourth driving member for driving the first clamping member to work to clamp or release the welding rod, and a fifth driving member for driving the second clamping member to work to clamp or release the welding rod.

[0009] With the above further setting, the welding rod on the feeding tray is fed towards the first welding mechanism by the feeding mechanism. The welding rod is inserted between the wiring board and the coil or between the static contact and the coil, and then welded by the first welding mechanism and the second welding structure. During the welding process, the feeding mechanism drives the welding rod to move away from the first welding mechanism, so that the welding rod is disconnected from the welding. The setting of the two clamping members can quantitatively convey the welding rod, avoiding excessive conveying of the welding rod and causing uneven welding spots.

The rotating seat is located at the discharge port of the wiring board loading channel. A receiving groove for receiving the wiring board is arranged on the rotating seat. When the receiving groove faces the wiring board loading channel, it is used to receive the horizontally placed wiring board. When the rotating seat rotates and the receiving groove faces upward, the wiring board is in a vertical state. The wiring board clamping member takes out the wiring board and places it in the wiring board placement groove.

[0011] With the above even further setting, the orientation of the wiring board is automatically changed from horizontal placement to vertical placement, which is convenient for subsequent assembly and welding. When the wiring board is located in the receiving groove, part of it is exposed, which is convenient for the wiring board clamping member to clamp the wiring board in the receiving groove.

The first sheet and the second sheet slide on the riveting and pressing tooling under the drive of the clamping assembly.

[0013] With the above even further setting, the two sheets are loaded and combined through the corresponding arranging tracks, riveted by the riveting member, and then the riveted static contact is placed in the static contact placement groove, realizing the automatic assembly and loading of the static contact with high processing efficiency.

[0014] A further improvement of the present utility model: The riveting tooling is arranged offset from the second alignment track, and a fixed seat is provided between the riveting tooling and the second alignment track. The pusher is slidably arranged on the fixed seat, and a receiving area for accommodating the second sheet is provided on the pusher.

[0015] With the above further improvement, the structure is simple and the feeding is convenient. The second sheet moves on the second alignment track. When the receiving area is aligned with the discharge port of the second alignment track, the foremost second sheet is pushed into the receiving area on the pusher. The pusher moves on the fixed seat, pushing the second sheet onto the riveting tooling, and the clamping assembly drives the second sheet to move towards the riveting part.

[0016] A further improvement of the present utility model: A coil adjustment station is further provided on the frame. The coil adjustment station is located between the coil feeding station and the welding station. An adjustment rod and a seventh driving member for driving the adjustment rod to slide towards the welding fixture are provided on the coil adjustment station.

[0017] With the above further improvement, the position of the coil in the coil placement groove is adjusted to avoid the coil position deviation, which may affect the subsequent welding effect.

[0018] A further improvement of the present utility model: A product inspection station is provided on the frame between the welding station and the blanking station. A vision sensor is provided on the product inspection station for detecting the welding result of the magnetic component.

[0019] With the above further improvement, after the magnetic component is welded, it is detected by the vision sensor to check whether the welding is completed and whether the welding is qualified, which is convenient for subsequent rejection of unqualified products.

[0020] A further improvement of the present utility model: A wiring board inspection station, a static contact inspection station and a coil inspection station are further provided on the frame. The wiring board inspection station is located behind the wiring board feeding station for detecting whether there is a wiring board in the wiring board placement groove. The static contact inspection station is located behind the static contact feeding station for detecting whether there is a static contact in the static contact placement groove. The coil inspection station is located behind the coil feeding station for detecting whether there is a coil in the coil placement groove.

[0021] With the above further improvement, it is detected whether the materials on the welding fixture are all fed, avoiding missing feeding and affecting subsequent welding.

[0022] A further improvement of the present utility model: A defective product discharge station is provided on the frame between the blanking station and the wiring board feeding station. A recycling box, a discharge claw and a discharge moving assembly for driving the claw to move between the welding fixture and the recycling box are provided on the defective product discharge station.

The first welding mechanism 62 includes a first welding head and an eighth driving member for driving the first welding head to move up and down in the vertical direction. The second welding mechanism 63 is located on the front side of the welding jig 21. The second welding mechanism 63 includes a second welding head and a driving assembly for driving the second welding head to slide in the horizontal direction. The driving assembly includes a motor, a rotating shaft, and a sliding seat 215. The second welding head is arranged on the sliding seat 215, and the sliding seat 215 slides on the rotating shaft to drive the second welding head to slide. A blanking channel 71 and a blanking clamping member 72 for clamping the welded magnetic component onto the blanking channel 71 are provided at the blanking station 7, realizing fully automatic assembly and welding, with high processing efficiency, good product quality, and high qualification rate. The wiring board, static contact, and coil are automatically fed through the feeding channels respectively, and each material is placed in the corresponding receiving groove 331 by the clamping member moving between the feeding channel and the welding jig 21. Then, the welding mechanism welds between the coil and the wiring board and between the coil and the static contact. After welding, the assembled and welded magnetic component is blanked through the blanking station 7.

[0050] The welding fixture 21 includes a base 214, a sliding seat 215, a coil placement rack 216, a wiring board placement seat 217, and a static contact placement seat 218. The coil placement rack 216 is provided with the coil placement groove 211, the wiring board placement seat 217 is provided with the wiring board placement groove 212, and the static contact placement seat 218 is provided with the static contact placement groove 213. The wiring board placement groove 212 and the static contact placement groove 213 are located on both sides of the coil placement groove 211. The sliding seat 215 is slidably arranged on the base 214. A first push rod 2151 and a second push rod 2152 are slidably arranged on the sliding seat 215. The coil placement rack 216 slides synchronously with the first push rod 2151. One of the wiring board placement seat 217 and the static contact placement seat 218 is arranged on the second push rod 2152, and the other is arranged on the sliding seat 215 or on a third push rod 2153 slidably arranged on the sliding seat 215. The coil placement rack 216, the wiring board placement seat 217, and the static contact placement seat 218 are all integrally or fixedly connected to the corresponding push rods. The fixed connection can be achieved by fixing them on the push rods through fasteners such as screws. It also includes a positioning member 219. The positioning member 219 is hinged to the coil placement rack 216. The upper end of the positioning member 219 is provided with a pressing arm. The contact part of the pressing arm with the coil is an arc surface adapted to the outer peripheral shape of the coil helix body, which fits the coil better, makes the coil structure stable, facilitates subsequent welding, and does not affect the welding effect.A positioning member return spring is provided between the lower end of the positioning member 219 and the coil placement rack 216. The upper end of the positioning member 219 is returned towards the coil placement rack 216 under the action of the positioning member return spring to form positioning of the coil by the pressing arm and the coil placement groove 211. A ninth driving member 14 is additionally provided on the frame 1 at the coil loading station 5, the unloading station 7, and the defective product discharging station 13, and is located on the front side of the positioning member 219.

When the pressing arm moves forward, it is convenient to place the coil into the coil placement groove 211 or remove it from the coil placement groove 211. When the pressing arm moves backward, it can press the coil in the coil placement groove 211 to fix it in the coil placement groove 211 and prevent the coil from moving, which affects the welding effect. The positioning member return spring can quickly reset the positioning member 219. Accommodation cavities are provided on both the lower end of the positioning member 219 and the coil placement rack 216, and both ends of the positioning member return spring are located in the corresponding accommodation cavities, making the structure of the return spring stable. At the same time, a driving mechanism is additionally provided at the rear end of the push rod. When the first push rod 2151 moves forward under the action of the driving mechanism, a gap is formed between the coil, the wiring board, and the static contact, which is convenient for inserting the welding sheet. If the welding sheet is inserted between the coil and the wiring board, the coil and the wiring board are first welded, and then the second push rod 2152 and the first push rod 2151 are pushed to slide forward synchronously, so that the coil and the wiring board slide forward synchronously, and a gap is formed between the coil and the static contact, which is convenient for inserting the welding sheet, and then the coil and the static contact are welded. Conversely, the coil and the static contact are welded first, and then the coil and the wiring board are welded. The slide block 215 and the base 214 are slidably matched through a guide rail and a guide groove. A fixing plate 2141 is provided at the rear side of the base 214. A slide block return spring 2142 for returning the slide block 215 forward is provided between the fixing plate 2141 and the slide block 215. A limiting block 2154 is provided on the slide block 215.

The rear ends of the push rods are the force-receiving ends, and a return block is provided at the force-receiving end. A push rod return spring is sleeved on each push rod, and the push rod return spring is compressed between the slide block 215 and the return block. The push rod is returned backward under the action of the push rod return spring, so that the push rod can be reset in time, and after the welding sheet is inserted between the coil and the wiring board or between the coil and the static contact, a clamping force is formed, and the welding effect is good.

[0051] There are two specific welding stations 6, and the structures of the two welding stations 6 are the same. One welding station 6 welds the coil and the wiring board, and the other welding station 6 welds the coil and the static contact. They can work synchronously, with high processing efficiency. The driving mechanism is arranged on the welding station 6. The driving mechanism includes a cylinder and a push plate arranged on the output shaft of the cylinder. It is also possible to set a single cylinder and use the output shaft of the cylinder to contact the push rod to drive the push rod to move forward. The feeding mechanism 61 includes a mounting bracket 611 and a feeding tray 612 arranged on the mounting bracket 611. The welding rod is wound around the feeding tray 612. A conveying component 613 for conveying the welding rod in the direction of the first welding mechanism 62 is arranged on the mounting bracket 611. The conveying component 613 includes a first clamping member 614 and a second clamping member 615 for clamping the welding rod, a second driving member 616 for driving the two clamping members to lift synchronously in the vertical direction, a third driving member 617 for driving the second clamping member 615 to lift independently in the vertical direction, a fourth driving member 618 for driving the first clamping member 614 to work to clamp or release the welding rod, and a fifth driving member 619 for driving the second clamping member 615 to work to clamp or release the welding rod. The welding rod on the feeding tray 612 is fed in the direction of the first welding mechanism 62 through the feeding mechanism 61. The welding rod is inserted between the wiring board and the coil or between the static contact and the coil, and then welded by the first welding mechanism 62 and the second welding structure. During the welding process, the feeding mechanism 61 drives the welding rod to move away from the first welding mechanism 62, so that the welding rod is disconnected from the welding. The setting of the two clamping members can quantitatively convey the welding rod to avoid excessive conveying of the welding rod and uneven welding spots. It also includes a pressure reducing valve 100. The pressure reducing valve 100 is connected to the second driving member 616. During welding, the second driving member 616 is decompressed by the pressure reducing valve 100, and the second driving member 616 drives the two clamping members to rise slowly, so that the welding rod breaks and the welding spots are uniform.Specifically, the first clamping member 614 includes a first fixed block 6141 and a first sliding block 6142 that are oppositely arranged in the transverse direction. The fourth driving member 618 is connected to the first sliding block 6142 and drives the first sliding block 6142 to slide in the transverse direction to clamp or release the welding electrode. The second clamping member 615 includes a second fixed block 6151 and a second sliding block 6152 that are oppositely arranged in the transverse direction. The fifth driving member 619 is connected to the second sliding block 6152 and drives the second sliding block 6152 to slide in the transverse direction to clamp or release the welding electrode. When the welding electrode is conveyed, the second sliding block 6152 slides away from the second fixed block 6151 under the action of the fifth driving member 619. The second sliding block 6152 and the second fixed block 6151 cooperate to clamp the lower end of the welding electrode, and under the action of the second driving member 616, the two clamping members move together towards the first welding mechanism 62 to convey the welding electrode. After being conveyed to a specific position, the first sliding block 6142 slides away from the first fixed block 6141 under the action of the fourth driving member 618 and no longer presses the lower end of the welding electrode. The second sliding block 6152 returns to its original position, cooperates with the second fixed block 6151 to clamp the welding electrode, and continues to convey the welding electrode to the first welding mechanism 62 under the drive of the third driving member. During the welding process of the two welding mechanisms, the second driving member 616 slowly drives the two clamping members to move away from the first welding mechanism 62, causing the welding electrode to break. After returning to the original position, the first sliding block 6142 and the first fixed block 6141 clamp the welding electrode, and the second sliding block 6152 and the second fixed block 6151 are loosened to continue the next round of conveying. A sliding plate 6111 is provided on the mounting frame 611. The output shaft of the second driving member 616 is connected to the sliding plate 6111, driving the sliding plate 6111 to move up and down on the mounting frame 611. The third driving member and the fourth driving member 618 are fixedly arranged on the sliding plate 6111 and slide synchronously with the sliding plate 6111. A guide rail is provided on the sliding plate 6111 in the vertical direction, and the second clamping member 615 is slidably arranged on the guide rail.

[0052] A rotating seat 33 and a sixth driving member 34 for driving the rotating seat 33 to rotate are further provided at the wiring board loading station 3. The sixth driving member 34 is a rotating cylinder or a motor. The rotating seat 33 is located at the discharge port of the wiring board loading channel 31. A receiving groove 331 for accommodating the wiring board is provided on the rotating seat 33. When the receiving groove 331 faces the wiring board loading channel 31, it is used to receive the horizontally placed wiring board. When the rotating seat 33 rotates and the receiving groove 331 faces upward, the wiring board is in a vertical state.
