Description

Technical Field

[0001] This invention relates to the field of capacitor shearing and welding equipment, specifically a self-positioning shearing and welding device for capacitor leads. Background Technology

[0002] As one of the most basic electronic components, capacitors are widely used in various electronic, communication and power equipment. In the production process of these capacitors, reliably welding the leads to the capacitor core is a key step that determines the final quality and performance of the product.

[0003] Currently, the cutting and welding of lead wires mainly rely on manual operation. Operators manually cut the coiled lead wires to the predetermined length, and then manually weld the lead wires to the electrodes of the capacitor element. The cutting length of the lead wires and the quality of the weld joints depend on the operator's operation, which can easily lead to problems such as inconsistent lead wire lengths, poor weld joints, and missing welds. In addition, the operators have a high labor intensity, which affects the production efficiency and the quality of the finished products. Summary of the Invention

[0004] The purpose of this invention is to provide a self-positioning cutting and welding device for capacitor leads, so as to solve the problems of high labor intensity and low product quality when manually cutting and welding capacitor leads in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a working chamber is included, in which a shearing device is installed, and a welding gun is installed on one side of the shearing device, the welding gun being connected to a control system; during operation, the capacitor lead wire is cut to a predetermined length by the shearing device, and then the processed lead wire is welded onto the capacitor element by the welding gun.

[0006] The shearing equipment includes a support plate and a cutting blade assembly. A wire feeding assembly is mounted on the support plate, and the cutting blade assembly is mounted on one side of the wire feeding assembly. A positioning assembly is mounted on one side of the cutting blade assembly and is mounted on the support plate. The welding gun is located on one side of the positioning assembly. The wire feeding assembly feeds out the capacitor lead wire to a predetermined length, and the cutting blade assembly cuts the lead wire fed out by the wire feeding assembly. Before cutting, the positioning assembly positions and clamps the lead wire to facilitate subsequent welding of the lead wire and capacitor element by the welding gun.

[0007] The cutting tool assembly includes a fixed tool assembly mounted on a support plate. A movable tool assembly is mounted on one side of the fixed tool assembly and slides on the support plate. A toggle element is slidably installed within the movable tool assembly, and a debris removal element is mounted on one side of the toggle element. The debris removal element is connected to the fixed tool assembly via a pipe and is also mounted on the support plate. During lead wire cutting, the movable tool assembly moves to the fixed tool assembly, clamps the lead wire, and then continues to move. The fixed and movable tool assemblies work together to cut the lead wire. Simultaneously, the debris removal element absorbs any metal debris that splashes during the cutting process, preventing it from affecting subsequent welding.

[0008] The wire feeding assembly includes a rotating element that rotates on a support plate. A clamping element is mounted on one side of the rotating element, and a winding box is mounted on the other side of the clamping element. By rotating the rotating element, a predetermined length of lead wire wound on the rotating element is released, and the clamping element presses down on the lead wire to ensure sufficient friction between the rotating element and the lead wire.

[0009] The fixed blade assembly includes a fixed plate mounted on a support plate. An air extraction box is installed on one side of the fixed plate. The air extraction box and a debris removal element are connected via a pipe. A first blade is installed on one side of the air extraction box, and an air suction nozzle is installed on one side of the first blade. During shearing of the lead wire, the debris removal element generates negative pressure at the air suction nozzle, causing metal debris generated during shearing to pass through the air extraction box and be transported to the debris removal element via the pipe.

[0010] The moving blade assembly includes a sliding plate that slides on a support plate. A mounting plate is mounted on one side of the sliding plate, and a second connecting rod is rotatably mounted on one side of the mounting plate. A first connecting rod is rotatably mounted on one side of the second connecting rod. A first rotating shaft is rotatably mounted on the support plate and mounted on the first connecting rod. A guide rod is slidably mounted on the mounting plate, and a horizontal plate is mounted on the guide rod. A second blade is mounted on one side of the horizontal plate. A first elastic element is installed between the mounting plate and the horizontal plate, and the first elastic element is sleeved on the guide rod. The first elastic element includes a first spring. During shearing, the first rotating shaft drives the first connecting rod to rotate, which in turn drives the second connecting rod to rotate. The second connecting rod causes the mounting plate to slide on the support plate towards the first blade. When the second blade contacts the first blade, the horizontal plate moves away from the first blade, compressing the first spring. The first and second blades first clamp the lead wire. When the positioning component clamps the lead wire, the shear stress on the lead wire reaches its maximum, and the second blade continues to move, cutting the lead wire.

[0011] The actuating element includes an actuating block that slides within a mounting plate. A first wedge block is mounted on one side of the actuating block, and a cylinder is mounted on the other side of the actuating block. A second elastic element is sleeved on the cylinder. One end of the second elastic element is mounted on the actuating block, and the other end of the second elastic element is mounted within the mounting plate. The second elastic element includes a second spring. When the mounting plate moves towards the first blade, the mounting plate causes the actuating block to move towards the first blade. The actuating block causes the first wedge block to press against the second wedge block. The first wedge block causes the second wedge block to move. When the piston plate moves to the first limiting ring, the second wedge block stops moving. The first wedge block slides on the second wedge block. The first wedge block causes the actuating block to move away from the mounting housing within the mounting plate. When the mounting plate moves away from the first blade, the mounting plate causes the actuating block to move away from the first blade. The actuating block causes the first wedge block to press against the second wedge block. The first wedge block causes the second wedge block to move. When the piston plate moves to the second limiting ring, the second wedge block stops moving. The first wedge block slides on the second wedge block. The first wedge block causes the actuating block to move away from the mounting housing within the mounting plate.

[0012] The cleaning element includes a mounting housing mounted on a support plate. A piston plate is slidably mounted inside the mounting housing. A piston rod is mounted on one side of the piston plate, and a second wedge block is mounted on one side of the piston rod. A third elastic element is mounted on the other side of the piston plate, with one end of the third elastic element mounted on the mounting housing. A first suction pipe, a second suction pipe, a suction pipe, and a drain pipe are mounted on the mounting housing. The first suction pipe is connected to the suction box via a pipe. A dust collection bag is mounted on one side of the drain pipe. One-way valves are installed inside the first suction pipe, the second suction pipe, the suction pipe, and the drain pipe. The third elastic element includes a third spring. A first limiting ring and a second limiting ring are also installed inside the mounting housing to limit the stroke of the piston plate. When the second wedge block moves the piston plate closer to the first blade, the third spring stretches, opening the one-way valves of the suction pipe and the drain pipe. The piston plate discharges impurities from the mounting housing into the dust collection bag through the drain pipe, preventing impurities from accumulating in the pipes. When the first wedge block moves away from the second wedge block, the third spring retracts, causing the piston plate to reset. At this time, the one-way valves of the first and second suction pipes open, generating a pulsed airflow at the suction nozzle, sucking debris into the mounting housing until the piston plate resets. When the first wedge block presses against the second wedge block, the first wedge block moves the second wedge block away from the first blade. At this time, the third spring compresses. When the first wedge block moves away from the second wedge block, the third spring stretches, causing the piston plate to reset, generating a pulsed airflow that flushes down debris adhering to the inner wall of the mounting housing, suspending it in the mounting housing for easy subsequent transport to the dust collection bag.

[0013] The rotating element includes a second rotating shaft that rotates on a support plate. A first driving component is mounted on one side of the second rotating shaft, and a first cam is mounted on the second rotating shaft. A fixed shaft is mounted on the support plate, and a rocker arm is rotatably mounted on the fixed shaft. A fourth elastic component is mounted on the fixed shaft, with one end of the fourth elastic component mounted on the rocker arm. One end of the rocker arm abuts against the first cam. A one-way bearing is mounted on the rocker arm, and a wire feeding wheel is mounted on the one-way bearing. The first driving component is connected to a control system. The fourth elastic component includes a torsion spring, and the first driving component includes a first servo motor. The first servo motor drives the second rotating shaft to rotate, and the second rotating shaft drives the first cam to rotate. When the flange of the first cam contacts the rocker arm, the flange causes the rocker arm to swing. The rocker arm drives the inner ring of the one-way bearing to rotate, and the inner ring drives the outer ring of the one-way bearing to rotate. The outer ring drives the wire feeding wheel to rotate, releasing a predetermined length of lead wire from the wire feeding wheel. When the base circle of the first cam contacts the rocker arm, the rocker arm resets via the torsion spring. At this time, the rocker arm drives the inner ring to rotate in the opposite direction within the outer ring, and the wire feeding wheel remains stationary.

[0014] The clamping element includes a fixed rod mounted on a support plate. A rocker arm is rotatably mounted on the fixed rod, and a clamping wheel is rotatably mounted on the rocker arm. A fifth elastic element is mounted on one end of the rocker arm, and the other end of the fifth elastic element is mounted on the support plate. The fifth elastic element includes a fifth spring, which pushes the rocker arm to move closer to the wire feeding wheel. The rocker arm causes the clamping wheel to press against the wire feeding wheel, ensuring sufficient friction between the wire feeding wheel and the lead wire.

[0015] The positioning assembly includes a clamping housing mounted on a support plate. A connecting plate is slidably mounted inside the clamping housing. An extension plate is mounted on one side of the connecting plate, and a clamping block is mounted on one side of the extension plate. A third wedge block is mounted on the other side of the connecting plate. A sixth elastic element is mounted on one side of the third wedge block, with one end of the sixth elastic element mounted on the clamping housing. A fourth wedge block is mounted on the other end of the third wedge block, and a protruding rod is mounted on the fourth wedge block. The protruding rod slides within the clamping housing. A third rotating shaft is rotatably mounted on the support plate, and a second cam is mounted on the third rotating shaft. The second cam abuts against the protruding rod. The first, second, and third rotating shafts are connected by a drive belt. The sixth elastic element includes a sixth spring. When the second blade contacts the first blade, the base circle of the second cam rotates to the protruding rod, causing the second cam to move the protruding rod away from the extension plate. The protruding rod then moves the fourth wedge block away from the extension plate. The sixth spring stretches, causing the third wedge block to move closer to the second cam. When the second blade reaches its maximum position, the clamping block clamps the lead wire.

[0016] The capacitor lead self-positioning shearing and welding device also includes an indexing plate located below the welding gun. A component clamp is mounted on the indexing plate, and a second driving component is installed at one end of the plate, connected to the control system. The second driving component includes a second servo motor, which drives the indexing plate to rotate, moving the component in the component clamp below the welding gun. When the clamping block clamps the lead, the welding gun is controlled to weld the lead and the capacitor component.

[0017] Compared with the prior art, the beneficial effects of the present invention are: This invention employs automatic shearing and welding technology, which can automatically shear and weld capacitor leads. The feeding length of the leads is controlled by a lead-out assembly, automatically releasing the predetermined length of lead and completing precise shearing at a preset position. Simultaneously, metal debris generated during the shearing action is promptly collected to prevent debris from splashing or remaining, which could cause short circuits, weak welds, or other quality issues in subsequent welding processes. After shearing, the treated leads are welded onto the capacitor element. The entire process requires no manual intervention, improving production efficiency and avoiding welding deviations caused by human factors, thereby enhancing the quality of the finished capacitor.

The welding gun 2 is connected to a control system. During operation, the shearing device 1 cuts the capacitor lead wire to a predetermined length, and then the welding gun 2 welds the processed lead wire onto the capacitor element.

[0022] The shearing device 1 includes a support plate 11 and a cutting blade assembly 12. A wire feeding assembly 13 is mounted on the support plate 11, and the cutting blade assembly 12 is mounted on one side of the wire feeding assembly 13. A positioning assembly 14 is mounted on one side of the cutting blade assembly 12 and is mounted on the support plate 11. The welding gun 2 is located on one side of the positioning assembly 14. The capacitor lead wire is fed out to a predetermined length through the wire feeding assembly 13, and the cutting blade assembly 12 cuts the lead wire fed out by the wire feeding assembly 13. Before cutting, the positioning assembly 14 positions and clamps the lead wire to facilitate subsequent welding of the lead wire and capacitor element by the welding gun 2.

[0023] The cutting blade assembly 12 includes a fixed blade assembly 121, which is mounted on a support plate 11. A movable blade assembly 122 is mounted on one side of the fixed blade assembly 121 and slides on the support plate 11. A toggle element 123 is slidably installed inside the movable blade assembly 122, and a debris removal element 124 is mounted on one side of the toggle element 123. The debris removal element 124 is connected to the fixed blade assembly 121 via a pipe and is mounted on the support plate 11. When cutting the lead wire, the movable blade assembly 122 moves to the fixed blade assembly 121, clamps the lead wire, and then continues to move. The fixed blade assembly 121 and the movable blade assembly 122 together cut the lead wire. At the same time, the debris removal element 124 absorbs the metal debris that splashes during the cutting process, preventing the debris from affecting subsequent welding.

[0024] The wire feeding assembly 13 includes a rotating element 131 that rotates on the support plate 11. A clamping element 132 is mounted on one side of the rotating element 131, and a winding box is mounted on the other side of the clamping element 132. By rotating the rotating element 131, a predetermined length of lead wire wound on the rotating element 131 is released, and the clamping element 132 presses against the lead wire to ensure sufficient friction between the rotating element 131 and the lead wire.

[0025] The fixed blade assembly 121 includes a fixed plate 1211, which is mounted on a support plate 11. A suction box 1212 is mounted on one side of the fixed plate 1211.

A first blade 1213 is mounted on one side of the suction box 1212, and a suction nozzle 1214 is mounted on one side of the first blade 1213. During shearing of the lead wire, the cleaning element 124 generates negative pressure at the suction nozzle 1214, causing metal debris generated during shearing to pass through the suction box 1212 and be transported through the pipe into the cleaning element 124.

[0026] The moving blade assembly 122 includes a sliding plate 1221 that slides on a support plate 11. A mounting plate 1222 is mounted on one side of the sliding plate 1221.

A first elastic element 1228 is installed between the mounting plate 1222 and the horizontal plate 1223 and is sleeved on the guide rod. The first elastic element 1228 includes a first spring. During shearing, the first rotating shaft 1225 drives the first connecting rod 1226 to rotate, the first connecting rod 1226 drives the second connecting rod 1227 to rotate, and the second connecting rod 1227 drives the mounting plate 1222 to slide on the bracket plate 11 towards the first blade 1213. When the second blade 1224 contacts the first blade 1213, the horizontal plate 1223 moves away from the first blade 1213. At this time, the first spring is compressed, and the first blade 1213 and the second blade 1224 first clamp the lead wire. When the positioning component 14 clamps the lead wire, the shear stress on the lead wire reaches its maximum. The second blade 1224 continues to move and cuts the lead wire.

[0027] The actuating element 123 includes an actuating block 1231, which slides within the mounting plate 1222. A first wedge block 1232 is mounted on one side of the actuating block 1231, and a cylinder 1233 is mounted on the other side of the actuating block 1231. A second elastic element 1234 is sleeved on the cylinder 1233. One end of the second elastic element 1234 is mounted on the actuating block 1231, and the other end of the second elastic element 1234 is mounted within the mounting plate 1222. The second elastic element 1234 includes a second spring. When the mounting plate 1222 moves toward the first blade 1213, the mounting plate 1222 drives the actuating block 1231 to move toward the first blade 1213. The actuating block 1231 drives the first wedge block 1232 to press against the second wedge block 1244. The first wedge block 1232 drives the second wedge block 1244 to move. When the piston plate 1242 moves to the first limiting ring, the second wedge block 1244 stops moving, and the first wedge block 1232 slides on the second wedge block 1244. The first wedge block 1232 drives the actuating block 1231 to move away from the mounting housing 12 within the mounting plate 1222. When the mounting plate 1222 moves away from the first blade 1213, the mounting plate 1222 drives the actuating block 1231 to move away from the first blade 1213. The actuating block 1231 drives the first wedge block 1232 to press on the second wedge block 1244. The first wedge block 1232 drives the second wedge block 1244 to move. When the piston plate 1242 moves to the second limit ring, the second wedge block 1244 stops moving. The first wedge block 1232 slides on the second wedge block 1244.

One-way valves are installed inside the first suction pipe 1246, the second suction pipe 1247, the suction pipe 1248, and the drain pipe 1249. The third elastic element 1245 includes a third spring. A first limiting ring and a second limiting ring are also installed inside the mounting housing 1241 to limit the stroke of the piston plate 1242. When the second wedge block 1244 drives the piston plate 1242 to move closer to the first blade 1213, the third spring is stretched, and the one-way valves of the suction pipe 1248 and the drain pipe 1249 open. The piston plate 1242 discharges impurities from the mounting housing 1241 into the dust collection bag through the drain pipe 1249, preventing impurities from accumulating in the pipe. When the first wedge block 1232 moves away from the second wedge block 1244, the third spring retracts, causing the piston plate 1242 to reset. At this time, the first suction pipe 1246 and the second... The one-way valve of the second suction pipe 1247 opens, generating a pulsed airflow at the suction nozzle 1214, which sucks the debris into the mounting housing 1241 until the piston plate 1242 returns to its original position. When the first wedge block 1232 presses against the second wedge block 1244, the first wedge block 1232 drives the second wedge block 1244 to move away from the first blade 1213. At this time, the third spring is compressed. When the first wedge block 1232 leaves the second wedge block 1244, the third spring stretches and drives the piston plate 1242 to return to its original position, generating a pulsed airflow that washes down the debris stuck to the inner wall of the mounting housing 1241, suspending it in the mounting housing 1241 for subsequent conveying to the dust collection bag.

The first servo motor drives the second rotating shaft 1312 to rotate, and the second rotating shaft 1312 drives the first cam 1311 to rotate. When the flange of the first cam 1311 contacts the rocker arm 1313, the flange drives the rocker arm 1313 to swing. The rocker arm 1313 drives the inner ring of the one-way bearing 1314 to rotate, and the inner ring drives the outer ring of the one-way bearing 1314 to rotate. The outer ring drives the wire feeding wheel 1315 to rotate, releasing a predetermined length of lead wire from the wire feeding wheel 1315. When the base circle of the first cam 1311 contacts the rocker arm 1313, the rocker arm 1313 is reset by the torsion spring.

The fifth elastic element 1323 includes a fifth spring, which pushes the rocker arm 1321 to move closer to the wire feeding wheel 1315. The rocker arm 1321 drives the clamping wheel 1322 to press against the wire feeding wheel 1315, ensuring sufficient friction between the wire feeding wheel 1315 and the lead wire.

The first rotating shaft 1225, the second rotating shaft 1312, and the third rotating shaft are connected by a transmission belt. The sixth elastic element 146 includes a sixth spring. When the second blade 1224 contacts the first blade 1213, the base circle of the second cam 148 rotates to the protrusion. The second cam 148 drives the protrusion to move away from the extension plate 144. The protrusion drives the fourth wedge block 147 to move away from the extension plate 144. The sixth spring stretches and drives the third wedge block 143 to move closer to the second cam 148. When the second blade 1224 moves to the maximum position, the clamping block 145 clamps the lead wire.

When the clamping block 145 clamps the lead, the welding gun 2 is controlled to weld the lead and the capacitor component.

[0033] Working principle of the invention: In use, the second servo motor is controlled to drive the indexing plate 3 to rotate, moving the element in the element clamp to below the welding gun 2. The first servo motor is controlled to drive the second rotating shaft 1312 to rotate. The second rotating shaft 1312 drives the first rotating shaft 1225 and the third rotating shaft to rotate via the transmission belt. The second rotating shaft 1312 drives the first cam 1311 to rotate. When the flange of the first cam 1311 contacts the rocker arm 1313, the flange drives the rocker arm 1313 to swing. The rocker arm 1313 drives the inner ring of the one-way bearing 1314 to rotate. The inner ring drives the outer ring of the one-way bearing 1314 to rotate. The outer ring drives the wire feeding wheel 1315 to rotate, releasing a predetermined length of lead wire from the wire feeding wheel 1315.

[0034] When the lead wire extends a predetermined length, the first rotating shaft 1225 drives the first connecting rod 1226 to rotate, the first connecting rod 1226 drives the second connecting rod 1227 to rotate, and the second connecting rod 1227 drives the mounting plate 1222 to slide on the bracket plate 11 towards the first blade 1213. When the second blade 1224 contacts the first blade 1213, the horizontal plate 1223 moves away from the first blade 1213. At this time, the first spring is compressed, and the first blade 1213 and the second blade 1224 first clamp the lead wire. The mounting plate 1225 then... 222 drives the actuating block 1231 to move closer to the first blade 1213. The actuating block 1231 drives the first wedge block 1232 to press on the second wedge block 1244. The first wedge block 1232 drives the second wedge block 1244 to move. When the piston plate 1242 moves to the first limiting ring, the second wedge block 1244 stops moving. The first wedge block 1232 slides on the second wedge block 1244. The first wedge block 1232 drives the actuating block 1231 to move away from the mounting housing 1241 within the mounting plate 1222.

[0035] When the second wedge block 1244 drives the piston plate 1242 to move closer to the first blade 1213, the third spring is stretched, and the one-way valves of the suction pipe 1248 and the drain pipe 1249 are opened. The piston plate 1242 discharges the impurities in the mounting housing 1241 into the dust collection bag through the drain pipe 1249, so that the impurities do not accumulate in the pipe. When the shear stress on the lead wire reaches its maximum, the second blade 1224 continues to move and cuts the lead wire. At this time, the first wedge block 1232 leaves the second wedge block 1244, and the third spring retracts to drive the piston plate 1242 to reset. At this time, the one-way valves of the first suction pipe 1246 and the second suction pipe 1247 are opened, and a pulse airflow is generated at the suction nozzle 1214, so that the metal fragments generated during shearing are transported to the mounting housing 1241 through the suction box 1212 and the pipe.

[0036] When the second blade 1224 contacts the first blade 1213, the base circle of the second cam 148 rotates to the protrusion. The second cam 148 drives the protrusion to move away from the extension plate 144. The protrusion drives the fourth wedge block 147 to move away from the extension plate 144. The sixth spring stretches and drives the third wedge block 143 to move closer to the second cam 148. When the second blade 1224 moves to the maximum position, the clamping block 145 clamps the lead wire to prevent it from falling when it is cut. When the clamping block 145 clamps the lead wire, the welding gun 2 is controlled to weld the lead wire and the capacitor element.

[0037] After welding is completed, the flange of the second cam 148 rotates to the protruding rod. The second cam 148 drives the protruding rod to move closer to the extension plate 144. The protruding rod drives the fourth wedge block 147 to move closer to the extension plate 144. The fourth wedge block 147 drives the third wedge block 143 to move away from the second cam 148. The fourth wedge block 147 drives the clamping block 145 to release the lead wire. At the same time, the second connecting rod 1227 drives the mounting plate 1222 to slide away from the first blade 1213 on the bracket plate 11. The mounting plate 1222 drives the actuating block 1231 to reset. When the actuating block 1231 moves to the second wedge block 1244, the first wedge block 1232 presses down. In the second wedge block 1244, the first wedge block 1232 drives the second wedge block 1244 to move away from the first blade 1213. At this time, the third spring is compressed. When the piston plate 1242 moves to the second limit ring, the first wedge block 1232 moves away from the second wedge block 1244. The third spring stretches and drives the piston plate 1242 to reset, generating a pulse airflow that flushes down the debris stuck to the inner wall of the mounting housing 1241, suspending it in the mounting housing 1241. This facilitates the subsequent transportation of the debris to the dust bag through the drain pipe 1249. The second servo motor is controlled to drive the indexing plate 3 to rotate, rotating the capacitor element to be welded to below the welding gun 2. The above steps are repeated.
