Description

Technical Field

[0001] This invention relates to the field of lead wire welding strength testing technology, and more specifically, to a lead wire laser welding strength testing device. Background Technology

[0002] To establish a low-resistance electrical path between the internal electrode tabs and the external metal leads of the capacitor, allowing current to flow from the core to the outside, leads are typically laser-welded onto the capacitor's electrode tabs. The strength of the weld joints is a key factor in determining the quality of the capacitor product, so it is necessary to test the weld strength of the capacitor leads. However, existing testing methods are limited and inconvenient for calculating weld strength. Furthermore, during testing, problems can easily arise where the leads or the capacitor detach from the testing equipment.

[0003] To address the above issues, some solutions have been provided in the existing technology, such as those with the following announcement number: Chinese invention patent application CN11577520A discloses a capacitor lead wire welding strength testing device. This device uses a strength testing control mechanism to move a control bar backward, causing its limiting bar and push bar to disengage from the limiting teeth and push teeth, respectively. The control disc rotates simultaneously, driving the drive shaft to rotate in the same direction through the connecting frame. Consequently, the drive wheel pushes the test bar upward. The tensile force borne by the weld is calculated based on the rotation angle of the control disc, facilitating the calculation of the weld connection strength. However, the prior art can only test one lead wire at a time, making it impossible to compare the welding strength of different groups of leads during testing. In addition, it seriously affects the testing efficiency. Summary of the Invention

[0004] To address the problems existing in the prior art, the purpose of this invention is to provide a lead laser welding strength testing device that can improve testing efficiency.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] A lead laser welding strength testing device includes a testing platform, on which vertical plates are uniformly fixedly installed, and electric push rods are fixedly installed on the vertical plates. A tension sensor is fixedly installed on the output end of the electric push rods. A first clamping plate is uniformly fixedly installed on the testing platform, and a limiting component is provided on the testing platform. The limiting component includes a mounting block slidably mounted on a detection table. A mounting rod is horizontally slidably mounted on the mounting block. A limiting plate is uniformly fixedly mounted on the mounting rod. A horizontal rod is slidably mounted on the limiting plate. A second clamping plate is fixedly mounted on the horizontal rod. A first spring is installed between the horizontal rod and the limiting plate. An electric telescopic rod with its output end fixedly connected to the horizontal rod is fixedly mounted on the mounting block. A clamping component that cooperates with a tension sensor is provided on the detection table.

[0007] Furthermore, the clamping assembly includes a mounting frame that is uniformly and fixedly installed on the detection table. The mounting frame is provided with a clamping rod, and a slide rod is slidably installed on the clamping rod. A second spring is installed between the slide rod and the clamping rod. A linkage plate is fixedly installed on the slide rod, and a connecting rod that cooperates with the clamping rod is fixedly installed on the tension sensor.

[0008] Furthermore, a first gear is rotatably mounted on the mounting frame, the first gear has a rectangular slot, a rectangular block is fixedly mounted on the clamping rod, a motor is fixedly mounted on the mounting frame, a rotating rod is fixedly mounted on the output end of the motor, and a second gear that meshes with the first gear is evenly fixedly mounted on the rotating rod.

[0009] Furthermore, a first magnet is fixedly installed on the slide rod, and an electromagnet that attracts the first magnet is fixedly installed on the clamping rod, and the electromagnet is electrically connected to the motor.

[0010] Furthermore, a sliding plate is symmetrically fixedly mounted on the mounting frame, and a horizontal groove that mates with a rectangular block is provided on the sliding plate. An annular plate is horizontally slidably mounted on the sliding plate, and a pull rod is fixedly mounted on both annular plates. The end of the connecting rod away from the tension sensor is fixedly connected to the pull rod.

[0011] Furthermore, the slide plate is provided with a groove, and a slider that is fixedly connected to the annular plate is slidably installed in the groove.

[0012] Furthermore, the rectangular block is provided with symmetrical oblique grooves.

[0013] Furthermore, anti-slip pads are fixedly installed on both the first clamping plate and the second clamping plate.

[0014] Furthermore, the rectangular blocks are provided in two sets, and the two sets of rectangular blocks are symmetrically arranged at both ends of the clamping rod.

[0015] Furthermore, corrugated grooves are provided on the side of the linkage plate opposite to the clamping rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) This solution uses a limiting component to clamp and fix the capacitor with the first clamping plate and the second clamping plate. The first spring between the horizontal rod and the limiting plate forms an elastic clamping structure. When testing capacitor leads of different sizes, there is no need to disassemble or replace the limiting tooling component. The elastic extension and contraction of the spring can adapt to capacitors of different sizes. Multiple sets of first clamping plates and second clamping plates are evenly arranged. The installation rod and the limiting plate are moved synchronously by the electric telescopic rod. Multiple sets of capacitors can be clamped and fixed at one time. The welding strength and tensile strength of multiple leads can be tested at the same time, which can effectively improve the testing efficiency. (2) To solve the technical problem that traditional direct pull-out tests are prone to lead wire slippage or non-solder joint breakage, this invention innovatively introduces a rotating clamping rod structure. Before the test, the motor drives the gear set to make the clamping rod rotate, and the thinner and smooth lead wire is pre-wound around the clamping rod. This structural design changes the stress state of the lead wire from single-point tension to distributed tension along the arc surface, which greatly increases the stress area, thereby ensuring that the breakage position is accurately located at the laser solder joint, and ensuring the authenticity and validity of the test data. (3) In this scheme, the electromagnet and the first magnet cooperate with each other. After the motor is powered on, the electromagnet is powered on and generates an electromagnetic field. Then, under the action of the electromagnetic field, the first magnet drives the slide rod to move downward. At this time, the second spring is compressed and has the tendency to recover. During the downward movement of the slide rod, the linkage plate moves downward and clamps the lead wire together with the clamping rod, thereby preventing the lead wire from falling off during the winding and testing process.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 7 A lead laser welding strength testing device includes a testing platform 101, on which vertical plates 102 are uniformly fixedly installed, and electric push rods 103 are fixedly installed on the vertical plates 102. A tension sensor 104 is fixedly installed on the output end of the electric push rods 103. A first clamping plate 105 is uniformly fixedly installed on the testing platform 101, and a limiting component 2 is provided on the testing platform 101. The limiting component 2 includes a mounting block 201 slidably mounted on the detection table 101. A mounting rod 202 is horizontally slidably mounted on the mounting block 201. A limiting plate 203 is uniformly fixedly mounted on the mounting rod 202. A horizontal rod 204 is slidably mounted on the limiting plate 203. A second clamping plate 205 is fixedly mounted on the horizontal rod 204. A first spring 206 is installed between the horizontal rod 204 and the limiting plate 203. An electric telescopic rod 207 with its output end fixedly connected to the horizontal rod 204 is fixedly mounted on the mounting block 201. The detection table 101 is provided with a clamping component 3 that cooperates with the tension sensor 104.

[0021] During testing, the capacitor is first placed between the first clamping plate 105 and the second clamping plate 205. Then, the output end of the electric telescopic rod 207 extends and drives the mounting rod 202 to move horizontally. During the movement of the mounting rod 202, multiple sets of limiting plates 203 move. During the movement of the limiting plates 203, the second clamping plate 205 moves closer to the first clamping plate 105 via the horizontal rod 204. During the movement of the second clamping plate 205, the capacitor comes into contact with the first clamping plate 105. Under the action of the first clamping plate 105 and the second clamping plate 205, the capacitor can be clamped and fixed. At the same time, under the action of the first spring 206, the capacitor can be adaptively clamped. To ensure the effectiveness of the destructive tensile test, the first spring 206 applies a pre-tightening pressure of P to the second clamping plate 205 under compression. Combined with the maximum static friction force f generated on the capacitor surface by the anti-slip pad 604, this maximum static friction force f must be greater than the ultimate breaking force F that the tension sensor 104 can apply during the test. This prevents the capacitor body from slipping or detaching during the test. Therefore, when testing capacitor leads of different specifications, there is no need to replace the limiting component 2. The leads are then clamped by the clamping component 3. The output end of the electric push rod 103 slowly retracts and pulls the leads through the tension sensor 104 and the clamping component 3. The tension sensor 104 then measures the tensile force on the leads when the solder joint breaks, thus testing the laser welding strength of the leads. Furthermore, by setting multiple sets of first clamping plates 105 and second clamping plates 205, multiple sets of capacitors can be clamped simultaneously during the movement of the horizontal rod 204, effectively improving testing efficiency.

[0022] like Figures 1 to 8 As shown, the clamping assembly 3 includes a mounting frame 301 uniformly fixedly installed on the detection table 101. The mounting frame 301 is provided with a clamping rod 302. A sliding rod 303 is slidably installed on the clamping rod 302. A second spring 304 is installed between the sliding rod 303 and the clamping rod 302. A linkage plate 305 is fixedly installed on the sliding rod 303. A connecting rod 306 that cooperates with the clamping rod 302 is fixedly installed on the tension sensor 104.

[0023] A first gear 401 is rotatably mounted on the mounting bracket 301. A rectangular slot 402 is provided on the first gear 401. A rectangular block 403 is fixedly mounted on the clamping rod 302. A motor 404 is fixedly mounted on the mounting bracket 301. A rotating rod 405 is fixedly mounted on the output end of the motor 404. A second gear 406 that meshes with the first gear 401 is evenly fixedly mounted on the rotating rod 405.

[0024] A first magnet 501 is fixedly installed on the slide bar 303, and an electromagnet 502 that attracts the first magnet 501 is fixedly installed on the clamping rod 302, and the electromagnet 502 is electrically connected to the motor 404.

[0025] The mounting bracket 301 is symmetrically fixedly mounted with a sliding plate 503, and the sliding plate 503 has a horizontal groove 504 that cooperates with the rectangular block 403. An annular plate 505 is horizontally slidably mounted on the sliding plate 503. The two annular plates 505 are jointly fixedly mounted with a pull rod 506, and the end of the connecting rod 306 away from the tension sensor 104 is fixedly connected to the pull rod 506.

[0026] By adopting the above technical solution, after fixing the capacitor, the lead wire is passed through the gap between the linkage plate 305 and the clamping rod 302. Then, the motor 404 drives the second gear 406 to rotate through the rotating rod 405. The second gear 406 drives the first gear 401 to rotate one revolution. During the rotation of the first gear 401, the clamping rod 302 is driven to rotate through the rectangular slot 402 and the rectangular block 403. During the rotation of the clamping rod 302, the lead wire can be wound around the clamping rod 302. Since the lead wire is thin and has a smooth surface, winding the lead wire around the clamping rod 302 can prevent the lead wire from falling off during the test. In addition, after the lead wire is wound around the clamping rod 302, a pushing force is applied to the lead wire. At this time, the arc surface of the clamping rod 302 applies a pulling force to the lead wire, thereby increasing the force-bearing area of ​​the lead wire, preventing the lead wire from breaking during the test, and further improving the test efficiency.

[0027] After the motor 404 is energized, the electromagnet 502 is energized and generates an electromagnetic field. Under the action of the electromagnetic field, the first magnet 501 drives the slide bar 303 to move downward. At this time, the second spring 304 is compressed and has a tendency to recover. During the downward movement of the slide bar 303, the linkage plate 305 moves downward and together with the clamping rod 302 clamps the lead wire, thereby preventing the lead wire from falling off during the winding and testing process. It should be noted that in order to avoid cable interference when the clamping rod 302 rotates, the end of the clamping rod 302 or the mounting bracket 301 is equipped with a conductive slip ring or brush assembly, and the electromagnet 502 is dynamically electrically connected to the motor 404 and the external control circuit through the conductive slip ring or brush assembly.

[0028] As the clamping rod 302 rotates, the loose lead wire is gradually wound around it. The motor 404 is preferably a servo motor or a stepper motor with an encoder. It should be noted that stepper motors or servo motors with encoders inherently possess extremely high angular displacement resolution and closed-loop position feedback control capabilities. Positioning accuracy typically reaches the pulse equivalent level, with minimal angular error. After emitting a preset number of pulses and cooperating with its built-in high-precision photoelectric encoder for closed-loop detection, it stops, achieving precise positioning and stopping. Under the control of the preset pulse program, the motor 404 drives the first gear 401 to precisely rotate the clamping rod 302 one revolution before stopping. The encoder on the motor 404 provides pulse closed-loop feedback, ensuring that after one revolution, the rectangular slot 402 is coaxially aligned with the horizontal slot 504. At this point, the electric push rod 103... The tension sensor 104, connecting rod 306, and pull rod 506 apply tension to the annular plate 505, and then the annular plate 505 applies tension to the clamping rod 302. Under the action of the tension, the clamping rod 302 drives the rectangular block 403 to enter the horizontal groove 504 along the rectangular groove 402 and slide along the horizontal groove 504. It should be noted that the connecting rod 306, pull rod 506 and electric push rod 103 are on the same horizontal straight tension axis, and the slider 602 on the annular plate 505 cooperates with the slide groove 601 of the slide plate 503 to provide rigid horizontal guidance, strictly eliminating lateral force component, and ensuring that the value detected by the tension sensor 104 is the horizontal breaking tension of the weld point. Moreover, each test station is symmetrically arranged along the tension axis. Therefore, under the rigid guiding constraint of the horizontal straight guide groove, the axial force transmitted to the tension sensor 104 is the horizontal tension. As the clamping rod 302 moves horizontally, the lead wire is gradually straightened. Then, as the clamping rod 302 continues to be pulled, the weld joint of the lead wire is gradually pulled apart, thus achieving the purpose of testing the laser welding strength of the lead wire.

[0029] When the lead wire solder joint is torn, the corresponding electric push rod 103 stops working. After multiple sets of lead wire tests are completed, the output end of the electric push rod 103 extends and drives the clamping rod 302 to reset via the tension sensor 104, connecting rod 306, pull rod 506, and annular plate 505. During the reset process of the clamping rod 302, the clamping rod 302 drives the rectangular block 403 to re-enter the rectangular groove 402 along the horizontal groove 504. At this time, the motor 404 is de-energized and the electromagnet 502 is de-energized. Then, the second spring 304 extends and drives the linkage plate 305 to move upward via the slide rod 303, thereby releasing the clamping of the lead wire. Then, the user can remove the tested lead wire. At the same time, the output end of the electric telescopic rod 207 retracts and drives the mounting rod 202 to reset. During the reset process of the mounting rod 202, the second clamping plate 205 is reset via the limit plate 203 and horizontal rod 204, thereby releasing the fixation of the capacitor. Then, the user can perform the next set of tests.

[0030] like Figures 3 to 7 As shown, the slide plate 503 has a groove 601, and a slider 602 that is fixedly connected to the annular plate 505 is slidably installed in the groove 601.

[0031] The rectangular block 403 has symmetrically formed inclined grooves 603.

[0032] Anti-slip pads 604 are fixedly installed on both the first clamping plate 105 and the second clamping plate 205.

[0033] By adopting the above technical solution, during the movement of the annular plate 505, the annular plate 505 will drive the slider 602 to slide along the groove 601. With the cooperation of the groove 601 and the slider 602, the annular plate 505 can only move in the horizontal direction. Furthermore, by symmetrically opening inclined grooves 603 on the rectangular block 403, it is convenient for the rectangular block 403 to enter the horizontal groove 504 along the rectangular groove 402, and it is also convenient for the rectangular block 403 to move out of the horizontal groove 504 again after the test is completed. In addition, the inclined grooves 603 symmetrically arranged at the front end of the rectangular block 403 form a guide chamfer, so that even if there are small tolerances, it can slide smoothly into the horizontal groove 504 from the center. Then, by setting the anti-slip pad 604, when the first clamping plate 105 and the second clamping plate 205 clamp the capacitor, the setting of the anti-slip pad 604 can increase the friction between the first clamping plate 105, the second clamping plate 205 and the capacitor, thereby improving the clamping effect of the capacitor.

[0034] like Figure 3 As shown, there are two sets of rectangular blocks 403, and the two sets of rectangular blocks 403 are symmetrically arranged at both ends of the clamping rod 302.

[0035] The linkage plate 305 and the clamping rod 302 are both provided with corrugated grooves 605 on the opposite side.

[0036] By adopting the above technical solution, and by symmetrically arranging two sets of rectangular blocks 403, when the second gear 406 drives the clamping rod 302 to rotate through the rectangular groove 402 and the rectangular blocks 403, both ends of the clamping rod 302 are simultaneously subjected to torque rotation. When the annular plate 505 drives the clamping rod 302 to move, the rectangular blocks 403 at both ends of the clamping rod 302 can limit the clamping rod 302 by cooperating with the two horizontal grooves 504, thereby improving the stability of the clamping movement. In addition, by setting the corrugated groove 605, when the sliding rod 303 drives the linkage plate 305 to clamp the lead wire, the linkage plate 305 and the corrugated groove 605 on the clamping rod 302 mesh with each other, thereby improving the clamping effect of the lead wire and effectively preventing the lead wire from falling off when the clamping rod 302 wraps around the lead wire.

[0037] Instructions for use: Place the welded capacitor workpiece to be inspected stably on the clamping station between the first clamping plate 105 and the second clamping plate 205 of the inspection table 101, ensuring it is level and that the workpiece is evenly stressed and fits snugly against the clamping area. Turn on the equipment control switch to extend the electric telescopic rod 207, causing the mounting rod 202 to move horizontally, simultaneously displacing each set of limit plates 203. During the movement of the limit plates 203, the horizontal rod 204 pushes the second clamping plate 205 slowly towards the first clamping plate 105 until the two clamping plates clamp the capacitor workpiece tightly. During this process, the first spring 206 can adaptively buffer and adjust the force to accommodate different capacitor specifications, preventing damage from excessive clamping or wobbling from excessive clamping.

[0038] The capacitor's solder leads are manually threaded through the gap between the clamping rod 302 and the linkage plate 305. The motor 404 and electromagnet 502 are powered, and the electromagnet 502 generates a magnetic attraction force, which attracts the first magnet 501 to move downward, causing the slide rod 303 to slide downward, compressing the second spring 304, and causing the linkage plate 305 to press down, cooperating with the clamping rod 302 to firmly clamp the leads.

[0039] The motor 404 drives the rotating rod 405 to rotate, which in turn drives the second gear 406 to mesh with the first gear 401. The first gear 401, through the engagement of the rectangular slot 402 and the rectangular block 403, drives the clamping rod 302 to rotate one revolution. During the rotation, the loose lead wire will be evenly wrapped around the clamping rod 302, increasing the force-bearing area of ​​the lead wire and preventing premature breakage or slippage of the lead wire during subsequent tensile testing. After the clamping rod 302 has rotated one revolution, the rectangular slot 402 and the horizontal slot 504 on the slide plate 503 are precisely aligned and connected, and the equipment automatically enters the tensile testing standby state.

[0040] When the electric push rod 103 is activated, its output end slowly retracts, pulling the pull rod 506 via the tension sensor 104 and connecting rod 306. Simultaneously, this causes the annular plates 505 on both sides to slide horizontally along the sliding plate 503. During the movement of the annular plates 505, the clamping rod 302 is pulled, causing the rectangular blocks 403 at both ends of the clamping rod 302 to slide from the rectangular groove 402 into the horizontal groove 504. These blocks then smoothly move horizontally along the horizontal groove 504, gradually straightening and tightening the lead wire wound on the clamping rod 302. As the electric push rod 103 continues to retract, the tension continuously increases, and the lead wire welding joint is continuously stressed until it cracks and falls off. Throughout the process, the tension sensor 104 collects and records the maximum tension value at the moment of lead wire breakage in real time; this value is the strength data of the lead wire laser welding.

[0041] After the lead wire solder joint breaks, the corresponding electric push rod 103 immediately stops working, automatically locks the test data, and completes the welding strength test. After all stations have been tested, the output end of the electric push rod 103 is extended and reset. Through the pull rod 506 and the annular plate 505, the clamping rod 302 is driven to slide in the opposite direction. The rectangular block 403 slides back from the horizontal groove 504 into the rectangular groove 402 of the first gear 401, and the clamping rod 302 returns to the initial rotation position.

[0042] When the power to motor 404 and electromagnet 502 is turned off, the magnetic attraction disappears, the second spring 304 returns to its original position, pushing the slide rod 303 and linkage plate 305 upwards, releasing the clamped lead wire and relieving its fixed state. The electric telescopic rod 207 retracts, causing the mounting rod 202 and limit plate 203 to reset, moving the second clamping plate 205 away from the first clamping plate 105, releasing the fixed capacitor workpiece. The inspected workpiece is manually removed, debris at the workstation is cleaned, and the inspection data is checked and saved. After the equipment is fully reset, the next batch of workpieces can be inspected.

[0043] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
