Description

TECHNICAL FIELD

[0001] The application relates to the technical field of laser welding equipment, in particular to laser welding equipment for electric vehicle controllers. BACKGROUND

[0002] The electric vehicle controller is a device for regulating the rotation speed, torque and power output of a motor through electronic signals, which can ensure that the electric vehicle safely and efficiently operates according to driving instructions (such as acceleration, deceleration and braking). The inductor coil on the controller circuit board is mainly used for energy buffering, high-frequency filtering and EMI suppression, and the selection and layout of the inductor coil directly affect the efficiency, stability and electromagnetic compatibility of the controller, and the inductor coil is one of the important electronic components of the electric vehicle controller.

[0003] At present, when laser welding an inductor coil, an operator usually fixes the inductor coil with a jig, then manually places a circuit board above the inductor coil, and adjusts a preset hole on the circuit board to be aligned with a pin of the inductor coil. In order to prevent the laser from damaging precise or sensitive components (such as ICs, sensors and patch inductors) on the circuit board, a high-temperature adhesive tape (such as a polyimide adhesive tape) or a metal plate is used to cover the surrounding components. However, before welding, the operator needs to fix the inductor line on the jig and also needs to fix the circuit board by hand. During welding, the welding precision may be reduced due to hand shaking, resulting in problems such as virtual welding and misalignment of welding points. Secondly, before fixing the inductor coil, it is necessary to check whether the pins are bent one by one, and if any abnormality is found, the inductor coil needs to be corrected. These steps seriously affect the work efficiency. Therefore, the application provides laser welding equipment for electric vehicle controllers to meet the needs. SUMMARY

[0004] The technical problem to be solved by the application is to provide laser welding equipment for electric vehicle controllers. By arranging a fixing assembly, the inductor coil can be fixed during laser welding, and the operator does not need to fix the inductor coil with the jig by hand, which avoids misalignment caused by hand shaking affecting the welding precision. In addition, the bent pins of the inductor coil can be corrected, and the operator does not need to check and correct the pins one by one with a correction tool, thereby improving the work efficiency of the operator. Furthermore, the pins of the inductor coil can be cleaned during the correction process to remove the oxidation layer and dust on the pins, further improving the welding quality, and solving the problem of low work efficiency.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above solution, by setting up a fixing component, the inductor coil can be fixed during laser welding without the need for workers to use their hands with a fixture to fix it, thus avoiding welding misalignment caused by hand tremors affecting welding accuracy. It can also correct bent leads of the inductor coil without workers having to check and correct each lead one by one with a straightening tool, thereby improving the work efficiency of workers. In addition, the leads of the inductor coil can be cleaned during the straightening process to remove the oxide layer and dust on the leads, further improving the welding quality.

[0018] By setting up sliding support columns, sliding protrusions, and a first sliding groove, not only can the circuit board be quickly positioned, saving workers' time, but the position of the guide cylinder can also be adjusted by rotating the first and second rotating handles according to the welding position of the inductor coil on the circuit board, providing convenience for subsequent welding work.

[0019] By setting up a step ring, a pull cable, a push plate, a third limit plate, a blocking plate, and an arc-shaped elastic plate, the inductor coil can be sent to the solder joint on the circuit board by stepping on the step ring, and the inductor coil can be fixed in place, avoiding problems such as cold solder joints and misalignment caused by vibration during soldering.

[0020] By setting up an installation cylinder, sliding hole, sliding column, pressing plate, push plate, second spring and installation box, the inductor coil can be continuously pushed into the guide cylinder by the push plate. After welding, there is no need to put the new inductor coil back onto the fixture, which saves the time of the workers and can also correct the inductor coil pins during the pushing process to avoid affecting subsequent welding.

[0021] By setting up a liquid reservoir, a first connecting groove, a second connecting groove, a collection cavity, a first sponge, and a second sponge, not only can the oxide layer and dust on the pins be cleaned, avoiding the problem of cold solder joints during laser welding, but also the residual cleaning agent on the cleaned inductor coil can be wiped away, preventing it from affecting laser welding and further preventing the problem of cold solder joints. In addition, the cleaning agent in the second sponge can be replenished when it is almost dry, so as not to affect the subsequent cleaning of the pins.

[0022] By setting up a first connecting plate, a second connecting plate, a third connecting plate, an S-shaped elastic plate, a second connecting post, and an N-shaped sliding plate, not only can the circuit board be fixed with the four support posts to avoid misalignment caused by vibration during laser welding, but also the second connecting post and the N-shaped sliding plate can be moved back and forth along the inner wall of the third sliding groove by the staff stepping on the foot ring, which in turn causes the second sponge to move back and forth, thereby further cleaning the oxide layer and dust on the inductor coil pins.

[0042] The laser welding equipment for electric vehicle controllers provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some known technologies; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0043] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0044] like Figures 1 to 15 As shown, an embodiment of the present invention provides a laser welding device for an electric vehicle controller, including a welding machine body 1. A support base 101 is mounted on the worktable of the welding machine body 1. The support base 101 is a square metal plate. Four support columns 104 are fixedly connected to the top outer wall of the support base 101. The support columns 104 are square metal columns, and the four support columns 104 are symmetrically positioned in pairs near the four corners of the support base 101 to support the circuit board. A first clearance circular hole 102 and a first sliding groove 103 are respectively opened on both sides of the top outer wall of the support base 101. The first clearance circular hole 102 is a circular groove, and the first sliding groove 103 is a circular groove. The device is a long, narrow groove with a convex cross-section. Two support columns 104 near the first sliding groove 103 have first limiting plates 108 fixedly connected to their top ends. The first limiting plates 108 are L-shaped metal plates. Two support columns 104 near the first clearance hole 102 have second limiting plates 107 fixedly connected to their top outer walls. The second limiting plates 107 are square metal plates. The cooperation between the two first limiting plates 108 and the two second limiting plates 107 holds the four corners of the circuit board, thus positioning the circuit board. A fixing assembly is used to fix the inductor coil and is connected to the support base 101.

[0045] This application, by setting up a fixing component, can not only fix the inductor coil during laser welding without the need for workers to use their hands with a fixture to fix it, thus avoiding welding misalignment caused by hand tremors affecting welding accuracy, but also correct the bent leads of the inductor coil. This eliminates the need for workers to check and correct each lead individually with a straightening tool, thereby improving the work efficiency of the workers. In addition, the lead of the inductor coil can be cleaned during the straightening process to remove the oxide layer and dust on the leads, further improving the welding quality.

[0046] In this embodiment, as Figures 1 to 5 and Figures 8 to 11As shown, the fixing assembly includes a sliding support column 5 slidably connected to the first sliding groove 103. The sliding support column 5 is a square metal column, and a sliding protrusion 501 is fixedly connected to the bottom end of the sliding support column 5. The sliding protrusion 501 is a convex metal block, and the outer contour of the sliding protrusion 501 matches the inner contour of the first sliding groove 103. Therefore, the sliding support column 5 can slide on the inner wall of the first sliding groove 103. A first threaded groove 502 is formed on the outer wall of the sliding support column 5 near the top. The first threaded groove 502 is a circular groove with threads on its inner wall. A second threaded groove 503 is formed on the outer wall of the sliding support column 5 near the bottom. The second threaded groove 503 is a circular groove with threads on its inner wall. Two support columns 104 near the first sliding groove 103 have a first rotating groove 106 and a second rotating groove 105 respectively formed on their outer walls near the bottom. The first rotating groove 106 is a circular groove with a convex cross-section, while the second rotating groove 105 is also a circular groove. A second threaded post 507 is screwed onto the inner wall of the second threaded groove 503. The second threaded post 507 is a metal post with threads on its outer wall, and the outer contour of the second threaded post 507 is adapted to the inner contour of the second threaded groove 503 and the inner contour of the second rotating groove 105. Therefore, the second threaded post 507 can rotate and move on the inner wall of the second threaded groove 503 and also rotate on the inner wall of the second rotating groove 105. One end of 507 is fixedly connected to a second rotating handle 508, which is a metal cylinder with an anti-slip groove on its outer wall. Rotating the second rotating handle 508 can drive the second threaded post 507 to rotate. The other end of the second threaded post 507 is fixedly connected to a second rotating protrusion 509, which is a convex metal cylinder. The outer contour of the second rotating protrusion 509 matches the inner contour of the first rotating groove 106. Therefore, the end of the second threaded post 507 away from the second rotating handle 508 passes through the second rotating groove 105 and the second threaded groove 503 in sequence and rotates on the inner wall of the first rotating groove 106. A first threaded post 504 is screwed onto the inner wall of the first threaded groove 502. 4 is a metal cylinder with threads on its outer wall. One end of the first threaded cylinder 504 is fixedly connected to a first rotating handle 505. The first rotating handle 505 is a metal cylinder with anti-slip grooves on its outer wall. Rotating the first rotating handle 505 can drive the first threaded cylinder 504 to rotate. The other end of the first threaded cylinder 504 is fixedly connected to a first rotating protrusion 506. The first rotating protrusion 506 is a convex metal cylinder. The end of the first threaded cylinder 504 away from the first rotating handle 505 is rotatably connected to a guide cylinder 2. The guide cylinder 2 is a square hollow metal cylinder. On the outer wall of the guide cylinder 2 near the first threaded cylinder 504, near the bottom, a first fixed cylinder 201 is fixedly connected. The first fixed cylinder 201 is a metal cylinder.A third rotating groove 202 is formed on the end wall of the first fixed cylinder 201 near the first threaded cylinder 504. The third rotating groove 202 is a circular groove with a convex cross-section. The inner wall contour of the third rotating groove 202 matches the outer wall contour of the first rotating protrusion 506. Therefore, the end of the first threaded cylinder 504 away from the first rotating handle 505 can rotate on the inner wall of the third rotating groove 202.

[0047] When the worker places the circuit board on top of the four support pillars 104, the four corners of the circuit board are restricted by two first limiting plates 108 and two second limiting plates 107 respectively, thereby achieving rapid positioning of the circuit board in the area to be soldered. Then, the second rotating handle 508 can be rotated clockwise. The second rotating handle 508 will drive the second threaded post 507 to rotate on the inner wall of the second rotating groove 105. Since the sliding support post 5 is restricted by the first sliding groove 103, it will not rotate with the rotation of the second threaded post 507. Instead, under the action of the second threaded groove 503, it will slide along the inner wall of the first sliding groove 103 towards the direction of the second rotating handle 508. Conversely, if the second rotating handle 508 is rotated counterclockwise, the sliding support post 5 will slide along the inner wall of the first sliding groove 103 towards the direction of the second rotating protrusion 509. At this time, if the first rotating handle 508 is rotated clockwise again, the sliding support post 5 will slide along the inner wall of the first sliding groove 103 towards the direction of the second rotating protrusion 509. Rotating handle 505 causes the first threaded post 504 to rotate. Since the sliding support post 5 is restricted by the first sliding groove 103, it will not rotate with the first threaded post 504. Therefore, the first threaded post 504 will rotate along the inner wall of the first threaded groove 502 and move towards the guide cylinder 2, thus pushing the guide cylinder 2 to move. Conversely, rotating the first handle 505 counterclockwise will cause the first threaded post 504 to rotate along the inner wall of the first threaded groove 502 and move away from the guide cylinder 2, thus pulling the guide cylinder 2 to move. The above structure not only allows for quick positioning of the circuit board, saving workers' time, but also allows for adjustment of the position of the guide cylinder 2 by rotating the first handle 505 and the second handle 508 according to the welding position of the inductor coil on the circuit board, providing convenience for subsequent welding work.

[0048] In this embodiment, as Figures 1 to 11As shown, a first clearance groove 203 is provided on the outer wall of the guide cylinder 2 on the side away from the first threaded post 504. The first clearance groove 203 is a square groove. Second clearance grooves 204 are symmetrically provided on the middle of the outer walls on both sides of the guide cylinder 2. The second clearance grooves 204 are also square grooves. Four arc-shaped elastic plates 205 arranged in a circular array are fixedly connected to the inner wall of the guide cylinder 2 near the top. The arc-shaped elastic plates 205 are arc-shaped plastic plates, with one end away from the inner wall of the guide cylinder 2 being open. When the arc-shaped elastic plate 205 is compressed, it will deform along its bending direction. One end of a first spring 6 is fixedly connected to the inner wall of the bottom of the guide cylinder 2. When the first spring 6 is compressed... When spring 6 is subjected to pressure, it deforms along its bending direction. The first spring 6 is prior art and will not be described in detail. A push plate 601 is fixedly connected to the other end of the first spring 6. The push plate 601 is a square metal plate, and its outer wall contour matches the inner wall contour of the guide cylinder 2. Therefore, the push plate 601 can slide on the inner wall of the guide cylinder 2. The push plate 601 is used to push the inductor coil towards the soldering position on the circuit board. A third limiting plate 607, also a square metal plate, is fixedly connected to the top outer wall of the push plate 601. A blocking device is fixedly connected to the outer wall of the push plate 601 on the side closest to the first fixed cylinder 201. Plate 604, the barrier plate 604 is a square metal plate, and the connection between the barrier plate 604 and the push plate 601 is provided with rounded corners. The barrier plate 604, with the rounded corners, can prevent the next inductor coil from entering the guide cylinder 2 during the process of the push plate 601 pushing the inductor coil to the solder joint of the circuit board. L-shaped fixing plates 602 are symmetrically fixed to the outer walls on both sides of the push plate 601. The L-shaped fixing plates 602 are L-shaped metal plates, and the outer contour of the L-shaped fixing plates 602 is adapted to the inner contour of the second clearance groove 204. Therefore, the L-shaped fixing plates 602 can slide on the inner wall of the second clearance groove 204, and the push plate 601 moves away from the barrier. A cable 605 is fixedly connected to one outer wall of plate 604. The cable 605 is made of metal, and the outer contour of the cable 605 matches the inner contour of the first clearance groove 203. Therefore, the first clearance groove 203 can avoid the cable 605 when it is pulled. The end of the cable 605 away from the push plate 601 passes through the first clearance groove 203 and is fixedly connected to the outer wall of the step ring 606. The step ring 606 is a metal ring with a triangular overall contour. The cable 605 and the step ring 606 are both existing technologies and will not be described in detail. The push plate 601 can slide along the inner wall of the guide cylinder 2 by pulling the cable 605 through the step ring 606.

[0049] When the operator steps on the foot ring 606, the foot ring 606 pulls the cable 605, causing the push plate 601 to slide along the inner wall of the guide cylinder 2 towards the bottom. This causes the first spring 6 to be stressed and deformed along its bending direction. Simultaneously, the L-shaped fixing plate 602, driven by the push plate 601, slides along the inner wall of the second clearance groove 204 towards the bottom of the guide cylinder 2. The blocking plate 604 moves with the push plate 601, releasing the obstruction on the inductor coil. The inductor coil is pushed onto the push plate 601. Under the restriction of the third limiting plate 607, only a single inductor coil is allowed to slide onto the push plate 601. When the operator releases the foot ring 606, the first spring 6... Spring 6, due to its own elastic recovery deformation, pushes the push plate 601 to slide upward along the inner wall of the guide cylinder 2. The L-shaped fixing plate 602 slides upward along the second clearance groove 204 along with the push plate 601. The push plate 601 delivers the inductor coil to the circuit board soldering point. The blocking plate 604 moves synchronously to the top of the guide cylinder 2, preventing the inductor coil from sliding into the guide cylinder 2 again, until the worker steps on the foot ring 606 again. The above structure can deliver the inductor coil to the soldering point on the circuit board by stepping on the foot ring 606 and fix the inductor coil, avoiding problems such as poor soldering and misalignment caused by vibration during soldering.

[0050] In this embodiment, as Figures 1 to 3 and Figures 7 to 11As shown, a mounting cylinder 3 is fixedly connected to the outer wall of the guide cylinder 2 near the first fixed cylinder 201. The mounting cylinder 3 is a square metal body. A sliding hole 303 is opened at the end of the mounting cylinder 3 away from the guide cylinder 2. The sliding hole 303 is a circular groove. A second sliding groove 301 is opened inside the mounting cylinder 3. The second sliding groove 301 is a square groove. A third clearance groove 302 is opened on the outer wall of one side of the mounting cylinder 3 near the bottom. The third clearance groove 302 is a square groove. A mounting box is slidably connected to the inner wall of the third clearance groove 302. The mounting box is a U-shaped metal plate, and the outer wall contour matches the inner wall contour of the third clearance groove 302. Therefore, the mounting box can slide on the inner wall of the third clearance groove 302. The mounting box is used to place several rows of... A row of inductor coils is arranged, and a sliding post 4 is slidably connected to the inner wall of the sliding hole 303. The sliding post 4 is a metal cylinder, and its outer contour matches the inner contour of the sliding hole 303, so the sliding post 4 can slide on the inner wall of the sliding hole 303. A push plate 401 is fixedly connected to one end of the sliding post 4. The push plate 401 consists of three parts: a square metal plate in the middle and square metal plates with inclined ends. It is used to push the inductor coils into the guide cylinder 2. A pressing plate 402 is fixedly connected to the other end of the sliding post 4. The pressing plate 402 is a metal circular plate, which facilitates the pusher to pull the sliding post 4. A second spring 403 is sleeved on the outer wall of the sliding post 4 near the push plate 401. One end of the second spring 403... The second spring 403 is fixedly connected to the outer wall of the push plate 401 near the pressing plate 402. The other end of the second spring 403 is fixedly connected to the inner wall near the sliding hole 303. When the second spring 403 is stressed, it will deform along its bending direction. Several first correction grooves 304 are provided on the outer wall of the mounting cylinder 3 near the third clearance groove 302. The first correction grooves 304 are square grooves. They can correct the pins on the inductor coil during the process of pushing the mounting box into the third clearance groove 302. Two second correction grooves 305 are provided on the top inner wall of the second sliding groove 301. The second correction grooves 305 are square grooves. They can correct the inductor coil during the process of pushing the inductor coil along the inner wall of the second sliding groove 301 towards the guide cylinder 2. The foot undergoes secondary correction. When the operator pulls the pressing plate 402, the pressing plate 402 will cause the sliding column 4 to slide along the inner wall of the sliding hole 303 away from the guide cylinder 2. The pushing plate 401 will move along with the sliding column 4, causing the second spring 403 to be stressed and deform along its bending direction. At this time, under the guidance of the inclined metal plate on the pushing plate 401, the mounting box filled with inductor coils is pushed into the third clearance groove 302. The pins on the inductor coils will be corrected by the first correction groove 304 until the upper side wall of the mounting box abuts against the inner wall of one side of the third clearance groove 302. After the first correction, the pins will slide along the inner wall of the first correction groove 304 into the second correction groove 305. At this time, the pressing plate 402 is released.The second spring 403 recovers its deformation under its own elasticity and pushes the pusher plate 401 towards the guide cylinder 2. The pusher plate 401 then pushes the inductor coil along the inner wall of the second sliding groove 301 towards the guide cylinder 2. During the sliding process of the inductor coil, the pins on the inductor coil are corrected by the second correction groove 305. This structure allows the pusher plate 401 to continuously push the inductor coil towards the guide cylinder 2. After welding, there is no need to place the new inductor coil back onto the fixture, saving workers' time and allowing for correction of the inductor coil pins during the pushing process, thus avoiding interference with subsequent welding.

[0051] In this embodiment, as Figures 1 to 3 and Figures 8 to 15As shown, a first connecting post 7 is fixedly connected to the outer wall near the middle of the top of the mounting cylinder 3. The first connecting post 7 is a square metal post. A first connecting plate 701 is fixedly connected to the end of the first connecting post 7 away from the mounting cylinder 3. The first connecting plate 701 is also a square metal plate. A second connecting plate 702 is fixed to one end of the first connecting plate 701. The second connecting plate 702 is a C-shaped metal plate. An S-shaped elastic plate 706 is fixedly connected to the other end of the first connecting plate 701. The S-shaped elastic plate 706 is an S-shaped metal plate that deforms along its bending direction when subjected to force. A third connecting plate 703 is fixedly connected to one end of the second connecting plate 702. The third connecting plate 703 is a square metal plate. The third connecting plate 703 is located away from the second connecting plate 702. One end of plate 702 is fixedly connected to a support plate 704, which is a hollow circular metal plate. The first connecting plate 701, the second connecting plate 702, the third connecting plate 703, the support plate 704, and the S-shaped elastic plate 706 are integrated structures. A third sliding groove 306 is formed on the outer wall of the top of the mounting cylinder 3 near the first connecting column 7. The overall outline of the third sliding groove 306 is an L-shaped groove, and the bottom inner wall outline is a W-shaped structure. A liquid storage cylinder 8 is fixedly connected to the top outer wall of the support plate 704. The liquid storage cylinder 8 is a hollow metal cylinder. An annular groove 804 is formed on the top outer wall of the liquid storage cylinder 8. The annular groove 804 is an annular groove with a square cross-section and threads on its outer and inner walls. A liquid storage cavity is formed on the bottom inner wall of the annular groove 804. 805, the liquid storage chamber 805 is an annular groove with a square cross-section. The liquid storage chamber 805 is a chamber used to store a special cleaning agent for inductor coils. A fourth threaded post 801 is screwed onto the inner wall of the annular groove 804. The fourth threaded post 801 is a hollow metal cylinder with threads on its outer wall. The outer contour of the fourth threaded post 801 matches the inner contour of the annular groove 804, so the fourth threaded post 801 can rotate on the inner wall of the annular groove 804. A pressing plate 803 is fixedly connected to the bottom end of the fourth threaded post 801. The pressing plate 803 is a hollow metal cylinder. The outer contour of the pressing plate 803 matches the inner contour of the liquid storage chamber 805, so the pressing plate 803 can slide on the inner wall of the liquid storage chamber 805. A fixed... A fourth rotating handle 802 is connected, which is a hollow metal cylinder with anti-slip grooves on its outer wall. Rotating the fourth rotating handle 802 drives the fourth threaded column 801 to rotate. The fourth threaded column 801 rotates along the inner wall of the annular groove 804 towards the bottom of the liquid storage cavity 805. The extrusion plate 803 follows the fourth threaded column 801 and rotates along the inner wall of the liquid storage cavity 805 towards the bottom of the liquid storage cavity 805. The support plate 704, the fourth rotating handle 802, the fourth threaded column 801, and the liquid storage cylinder 8 are all hollow to avoid laser interference. The target welding position is located in the hollow part. The inner wall of the S-shaped elastic plate 706 away from the first connecting plate 701 has a collection cavity 807.The collecting cavity 807 is a long, narrow groove with a square cross-section. Symmetrical first connecting grooves 806 are formed on both sides of the top inner wall of the collecting cavity 807. Each first connecting groove 806 is an annular groove with a circular cross-section. The end of the first connecting groove 806 furthest from the collecting cavity 807 is connected to the liquid storage cavity 805, allowing cleaning agent from the liquid storage cavity 805 to be transported into the collecting cavity 807. A second connecting post 707 is fixedly connected to the end of the S-shaped elastic plate 706 furthest from the first connecting plate 701. The second connecting post 707 is a square metal post. An N-shaped sliding plate 709 is fixedly connected to the bottom end of the protrusion 708. The N-shaped sliding plate 709 is a metal plate with an N-shaped structure, and grooves adapted to the second correction groove 305 are opened on both outer walls to avoid the pins. A second connecting groove 808 is opened inside the second connecting post 707. The second connecting groove 808 is a circular groove. One end of the second connecting groove 808 is connected to the bottom inner wall of the collecting cavity 807, and the other end of the second connecting groove 808 extends through the top outer wall of the N-shaped sliding plate 709. A second sponge is installed on the inner wall of the N-shaped sliding plate 709. 9. The overall outline of the second sponge 9 is square, and the outline of its bottom outer wall is W-shaped. The outline of the outer wall of the second sponge 9 matches the outline of the inner wall of the N-shaped slide plate 709, so the second sponge 9 can be stuck on the inner wall of the N-shaped slide plate 709. The cleaning agent in the collection cavity 807 will flow into the second sponge 9 through the second connecting groove 808. Since the bottom inner wall of the third sliding groove 306 mentioned above is W-shaped, this can reduce the situation of cleaning agent flowing into the outer wall of the inductor coil when cleaning the pin. The second sponge 9 has a sixth sliding groove symmetrically opened on both sides of its bottom outer wall. The moving groove 901 and the sixth sliding groove 901 are T-shaped grooves, and the two sixth sliding grooves 901 are respectively aligned with the two second correction grooves 305. Several second segmented grooves 902 are symmetrically arranged in a linear array on both sides of the bottom outer wall of the second sponge 9 near the sixth sliding grooves 901. The second segmented grooves 902 are square grooves, which facilitates better contact and deformation of the second sponge 9 with the outer wall of the pin. The cooperation between the sixth sliding grooves 901 and the second segmented grooves 902 improves the removal effect of oxide layer and dust on the outer wall of the pin.

[0052] A mounting groove 307 is formed on the inner wall of the second sliding groove 301 near the guide cylinder 2. The mounting groove 307 is a rectangular groove, and a first sponge 903 is installed inside the mounting groove 307. The first sponge 903 is a cuboid-shaped sponge, and a fourth sliding groove 904 is formed on the first sponge 903. The fourth sliding groove 904 is a square groove, and its overall outline is slightly smaller than that of the second sliding groove 301. This facilitates better contact with the outer wall of the inductor coil and improves the erasing effect. Two fifth sliding grooves 905 are symmetrically formed on both sides of the top inner wall of the fourth sliding groove 904. The positions of the two fifth sliding grooves 905 correspond to the positions of the two correction grooves. The fifth sliding grooves 905 are T-shaped. The groove with a rectangular structure has an overall outline slightly smaller than that of the second correction groove 305, which facilitates better contact with the outer wall of the pin and improves the erasing effect. The inner top wall of the fourth sliding groove 904, near the sides of the fifth sliding groove 905, has several first segmented grooves 906 arranged in a linear array. The first segmented grooves 906 are square, which facilitates better contact and deformation of the first sponge 903 with the outer wall of the pin. During the process of pushing the inductor coil towards the guide cylinder 2, residual cleaning agent on the outer wall of the inductor coil and the outer wall of the pin is wiped away. During the process of the push plate 401 pushing the inductor coil along the inner wall of the second sliding groove 301 towards the guide cylinder 2, the pins on the inductor coil... The inductor will slide along the inner wall of the second correction groove 305 into the third sliding groove 306. The sixth sliding groove 901 on the second sponge 9, which is soaked in cleaning agent, will clean the oxide layer and dust on the pins. After cleaning, the inductor coil will be pushed into the mounting groove 307. The fourth sliding groove 904 and the two fifth sliding grooves 905 on the first sponge 903 will wipe away the residual cleaning agent on the outer wall of the inductor coil and the outer wall of the pins, respectively. When the operator feels that there is not enough cleaning agent in the second sponge 9, the fourth rotating handle 802 can be rotated to drive the fourth threaded post 801 to rotate. The fourth threaded post 801 will rotate along the inner wall of the annular groove 804 towards the liquid storage chamber 8. The bottom of the 05 moves, and the extrusion plate 803 follows the fourth threaded post 801, rotating along the inner wall of the liquid storage cavity 805 towards the bottom of the liquid storage cavity 805. This pushes the cleaning agent through the first connecting groove 806, the collection cavity 807, and the second connecting groove 808 to the second sponge 9. The above structure not only removes the oxide layer and dust on the pins, avoiding the problem of poor soldering during laser welding, but also removes the residual cleaning agent on the cleaned inductor coil, preventing it from affecting laser welding and further preventing the problem of poor soldering. In addition, the cleaning agent in the second sponge 9 can be replenished when it is almost dry, so as not to affect the subsequent cleaning of the pins.

[0053] In this embodiment, as Figures 1 to 6 and Figures 8 to 13As shown, a fourth rotating groove 712 is formed on the outer wall of the top of the first connecting plate 701 near the second connecting plate 702. The fourth rotating groove 712 is a circular groove. A second fixed cylinder 710 is fixedly connected to the outer wall of the top of the third connecting plate 703 near the second connecting plate 702. The second fixed cylinder 710 is a metal cylinder. A third threaded groove 711 is formed on the outer wall of the top of the second fixed cylinder 710. The third threaded groove 711 is a circular groove with threads on its inner wall. A third threaded post 713 is screwed onto the inner wall of the third threaded groove 711. The third threaded post 713 is a metal cylinder with threads on its outer wall. The outer contour of the third threaded post 713 is respectively connected to the fourth rotating groove 702. The inner wall contour of 12 matches the inner wall contour of the third threaded groove 711, so the third threaded column 713 can rotate on the inner wall of the third threaded groove 711 and the inner wall of the fourth rotating groove 712 respectively. A third rotating handle 714 is fixedly connected to the top of the third threaded column 713. The third rotating handle 714 is a metal cylinder with an anti-slip groove on its outer wall. A fixing circular plate 715 is fixedly connected to the bottom of the third threaded column 713. The fixing circular plate 715 is a metal circular plate used to prevent the third threaded column 713 from sliding out of the fourth rotating groove 712. A weakening groove 705 is formed on the outer wall of the second connecting plate 702 near the third threaded column 713. The weakening groove 705 is an arc-shaped groove. The design allows the second connecting plate 702 to deform better along its bending direction after being subjected to force. When the operator rotates the third rotating handle 714 clockwise, it will cause the third threaded post 713 to rotate. Since the first connecting plate 701 is fixed to the top of the mounting cylinder 3 through the first connecting post 7, and the third connecting plate 703 and the first connecting plate 701 are an integrated structure, the third connecting plate 703 will not rotate with the third threaded post 713 under the action of the third threaded groove 711. Instead, it will move along the outer wall of the third threaded post 713 towards the first connecting plate 701. At this time, the second connecting plate 702 will be subjected to force and deform along its bending direction. At the same time, the support plate 70... The 4 will move along with the third connecting plate 703 and press against the circuit board. With the support of the four support columns 104, the circuit board can be fixed. Conversely, when the operator rotates the third rotating handle 714 counterclockwise, the third connecting plate 703 will move along the outer wall of the third threaded column 713 away from the first connecting plate 701. The second connecting plate 702 will no longer be under force and will restore its deformation along its bending direction. The support plate 704 will move along with the third connecting plate 703 and be removed from the circuit board, thus releasing the circuit board from its fixation. In addition, the support plate 704 can also cover the precision or sensitive components on the circuit board to prevent laser damage during soldering.

[0054] Second connecting protrusions 708 are fixedly connected to the outer walls of both sides of the second connecting post 707 near one end of the S-shaped elastic plate 706. Each second connecting protrusion 708 consists of a metal cylinder and a metal plate. The portion near the second connecting post 707 is a metal cylinder, and the portion away from the second connecting post 707 is a metal plate. A connecting plate is rotatably connected to the outer wall of the cylindrical portion of the second connecting protrusion 708. The connecting plate is a metal plate with curved ends, and symmetrical rotating holes, which are circular grooves, are formed on the outer walls near both ends of the connecting plate. The inner wall contour of the rotating hole matches the outer wall contour of the metal cylinder on the second connecting protrusion 708, so the connecting plate can rotate on the outer wall of the second connecting protrusion 708. A first connecting protrusion 603 is fixedly connected to the outer wall of the L-shaped fixing plate 602 on the side away from the push plate 601. The first connecting protrusion 603 consists of a metal cylinder and a metal disc, with the part closer to the L-shaped fixing plate 602 being the metal cylinder and the part farther from the L-shaped fixing plate 602 being the metal disc. The inner wall contour of the rotating hole on the connecting plate away from the second connecting protrusion 708 matches the outer wall contour of the first connecting protrusion 603. The outer wall contour of the upper metal cylinder is adapted to the shape, so the connecting plate can also rotate on the outer wall of the first connecting protrusion 603. When the L-shaped fixing plate 602 moves towards the bottom of the guide cylinder 2 following the push plate 601, the second connecting column 707 and the N-shaped sliding plate 709 will slide along the inner wall of the third sliding groove 306 towards the guide cylinder 2 under the action of the connecting plate. At this time, the S-shaped elastic plate 706 will be subjected to force and deform along its bending direction. Conversely, when the L-shaped fixing plate 602 moves towards the top of the guide cylinder 2 following the push plate 601, the second connecting column 707 and the N-shaped sliding plate 709 will slide along the inner wall of the third sliding groove 306 towards the guide cylinder 2 under the action of the connecting plate. The connecting post 707 slides along the inner wall of the third sliding groove 306 away from the guide cylinder 2. At the same time, the S-shaped elastic plate 706 is no longer under force and recovers its deformation along its bending direction. The above structure not only works with the four support posts 104 to fix the circuit board and avoid the circuit board shifting due to vibration during laser welding, thus preventing welding misalignment; but also allows the second connecting post 707 and the N-shaped sliding plate 709 to slide back and forth along the inner wall of the third sliding groove 306 by the worker stepping on the foot ring 606, causing the second sponge 9 to move back and forth, thereby cleaning the oxide layer and dust on the inductor coil pins.

[0055] The working principle of the technical solution provided by this invention is as follows:

[0056] During use, when the operator places the circuit board on top of the four support pillars 104, the four corners of the circuit board are restricted by two first limiting plates 108 and two second limiting plates 107 respectively, thereby achieving rapid positioning of the circuit board in the area to be soldered. Then, the second rotating handle 508 can be rotated clockwise. The second rotating handle 508 drives the second threaded post 507 to rotate along the inner wall of the second rotating groove 105. Because the sliding support post 5 is restricted by the first sliding groove 103 and cannot rotate with the second threaded post 507, it moves along the inner wall of the first sliding groove 103 towards the second rotating handle 508 under the action of the second threaded groove 503. The sliding column 5 slides in the direction of the first sliding groove 103 towards the second rotating protrusion 509 when the second rotating handle 508 is rotated counterclockwise. At this time, the first rotating handle 505 is rotated clockwise, which drives the first threaded column 504 to rotate. The sliding support column 5 is also restricted by the first sliding groove 103, causing the first threaded column 504 to rotate along the inner wall of the first threaded groove 502 and move towards the guide cylinder 2, pushing the guide cylinder 2 to move. Conversely, the first rotating handle 505 is rotated counterclockwise, and the first threaded column 504 rotates in the opposite direction along the inner wall of the first threaded groove 502, pulling the guide cylinder 2 away.

[0057] When the third rotating handle 714 is rotated clockwise, the third rotating handle 714 drives the third threaded post 713 to rotate. Since the first connecting plate 701 is fixed to the top of the mounting cylinder 3 through the first connecting post 7, and the third connecting plate 703 and the first connecting plate 701 are an integral structure, the third connecting plate 703 does not rotate with the third threaded post 713 under the action of the third threaded groove 711. Instead, it moves along the outer wall of the third threaded post 713 toward the first connecting plate 701, forcing the second connecting plate 702 to be stressed and deformed along its bending direction. At the same time, the support plate 704 moves with the third connecting plate 703 and presses on the circuit board, which, together with the four support posts 104, achieves the fixation of the circuit board. Conversely, when the third rotating handle 714 is rotated counterclockwise, the third connecting plate 703 moves away from the first connecting plate 701 along the outer wall of the third threaded post 713. The second connecting plate 702 recovers its deformation, and the support plate 704 moves with the third connecting plate 703 and releases the fixation of the circuit board.

[0058] When the pressing plate 402 is pulled, the pressing plate 402 drives the sliding column 4 to slide away from the guide cylinder 2 along the inner wall of the sliding hole 303. The pushing plate 401 moves with the sliding column 4, causing the second spring 403 to deform under force. At this time, under the guidance of the inclined metal plate of the pushing plate 401, the mounting box filled with inductor coils is pushed into the third clearance groove 302. The inductor coil pins are initially corrected by the first correction groove 304. After the upper side wall of the mounting box touches the inner wall of the third clearance groove 302, the pins slide into the second correction groove 305 along the inner wall of the first correction groove 304. When the pressing plate 402 is released, the second spring 403 returns to its deformation and pushes the pushing plate 401 to move towards the guide cylinder 2. The pushing plate 401 pushes the inductor coil to slide along the inner wall of the second sliding groove 301. During the process, the pins are corrected a second time by the second correction groove 305. This structure continuously pushes the inductor coil through the pushing plate 401, avoiding manual feeding after welding, saving time, and completing pin correction during the pushing process to ensure welding quality.

[0059] When the push plate 401 pushes the inductor coil along the second sliding groove 301 toward the guide cylinder 2, the pin slides along the inner wall of the second correction groove 305 into the third sliding groove 306. The sixth sliding groove 901 on the second sponge 9, which is soaked with cleaning agent, removes the oxide layer and dust on the pin. The cleaned inductor coil is pushed to the mounting groove 307. The fourth sliding groove 904 and the two fifth sliding grooves 905 on the first sponge 903 wipe the cleaning agent residue on the outer wall of the inductor coil and the pin, respectively.

[0060] When the foot ring 606 is pressed down, it pulls the cable 605, causing the push plate 601 to slide along the inner wall of the guide cylinder 2 towards the bottom, and the first spring 6 deforms under force. At the same time, the L-shaped fixing plate 602 slides down along the inner wall of the second clearance groove 204 with the push plate 601, and drives the second connecting column 707 and the N-shaped sliding plate 709 to slide along the inner wall of the third sliding groove 306 towards the guide cylinder 2 through the linkage plate. The S-shaped elastic plate 706 deforms under force, and the blocking plate 604 moves down with the push plate 601 to release the obstruction of the inductor coil. Under the restriction of the third limiting plate 607, only a single inductor coil is allowed to slide into the push plate 601. When the foot ring 606 is released, the first spring 6 returns to its deformation and pushes. The push plate 601 moves upward, and the L-shaped fixing plate 602 moves upward simultaneously. The linkage plate drives the second connecting column 707 away from the guide cylinder 2 along the inner wall of the third sliding groove 306. The S-shaped elastic plate 706 recovers its deformation. The push plate 601 delivers the inductor coil to the circuit board soldering point. The blocking plate 604 moves upward to block the subsequent inductor coils again until the step ring 606 is stepped on again. At this time, the welding head on the welding machine body 1 starts and emits a laser that passes through the hollow channels of the fourth rotating handle 802, the fourth threaded column 801, the liquid storage cylinder 8, and the support plate 704 in sequence, soldering the pins of the inductor coil to the soldering position on the circuit board. After the soldering is completed, the operator can replace the circuit board and repeat the above operation.
