Description

Technical Field

[0001] This invention relates to the field of electrical switch welding technology, and in particular to a welding device for internal components of electrical switches. Background Technology

[0002] Welding of internal components in electrical switches is a crucial process for ensuring reliable connections between the various electrical components within the switch. Welding involves using heat or pressure to fix components such as wires, electrodes, and contacts together, forming a stable electrical connection.

[0003] The prior art publication CN117921269A provides a welding device for a high-voltage switch stationary contact seat. By combining a flow guiding component and an air outlet mechanism, the flow guiding component adjusts the fluid resistance according to the air volume, thereby balancing the air volume and resistance in a timely manner. This effectively prevents overheating of the welding area while reducing the escape of protective gas, thus improving welding efficiency and quality.

[0004] Existing technologies for soldering wires inside electrical switches suffer from drawbacks. The inconvenience of bending and soldering the wires leads to insufficient contact area, low mechanical strength, and potential misalignment or displacement during soldering, making it difficult to adapt to spatial layouts. These issues negatively impact the soldering quality and stability of the electrical switch, ultimately affecting the overall performance and reliability of the product.

[0005] In summary, the existing technology lacks the technique for bending and soldering the internal wires of electrical switches. Summary of the Invention

[0012] Preferably, the transmission mechanism includes a universal joint, which is rotatably connected to the fixed frame. A pressing rod is fixedly connected to one end of the universal joint, and the pressing rod is in sliding contact with the upper surface of the wire bending seat.

A tension spring B is fixedly connected to one end of each transmission tooth, and the other end of the tension spring B is fixedly connected to the inner wall of the universal joint. A gear sleeve is rotatably connected to the outer wall of the end of the universal joint near the transmission teeth. Multiple tooth grooves are formed on the inner wall of the gear sleeve, and the tooth grooves on the inner wall of the gear sleeve are movably engaged with the transmission teeth for transmission.

[0013] Preferably, one end of the rotating frame passes through the fixed frame and is fixedly connected to a motor A, the motor A is fixedly connected to the fixed frame, and a sector gear is fixedly connected to the outer wall of one end of the rotating frame, the sector gear meshing with a gear sleeve for transmission.

[0014] Preferably, the wire clamping mechanism includes an electric actuator A, which is fixedly connected to a rotating frame.

[0018] 2.

Precise control and automated operation not only improve product consistency and quality stability, but also optimize the production process and reduce costs.

[0019] 3. By installing a spring-connected pressing plate inside the unloading rack, the wire can be pushed onto the loading wheel. Simultaneously, as the conveyor belt moves the switch housing placement seat, transporting the switch housing to the welding position, it automatically drives the loading wheel to rotate, transporting the wire to be pressed to the upper side. This enables precise positioning and stable transport of the wire, which not only improves production efficiency and reduces human error, but also ensures welding accuracy and stability, optimizes spatial layout, reduces operational difficulty, and increases the automation level of the production line, effectively improving overall production quality and reducing production costs.

Detailed Implementation

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-8 The welding device for internal components of an electrical switch shown includes a conveyor frame 1, a conveyor belt 2 rotatably connected to the conveyor frame 1, a fixed frame 3 fixedly connected to the conveyor frame 1, a feeding wheel 4 rotatably connected to one side of the fixed frame 3, a feeding rack 5 fixedly connected to the fixed frame 3, a wire bending seat 6 slidably fitted on the fixed frame 3, a transmission mechanism 7 rotatably connected to the other side of the fixed frame 3, a rotating frame 8 rotatably connected to the fixed frame 3, a wire clamping mechanism 9 slidably fitted on the rotating frame 8, and a welding robotic arm 10 fixedly mounted on the conveyor frame 1.

[0031] like Figure 2 As shown, multiple switch housing placement seats 201 are fixedly connected to the conveyor belt 2, and a pulley on one side of the conveyor belt 2 extends through the inner wall of the conveyor frame 1 to the outside and is fixedly connected to a drive wheel 202.

[0032] like Figure 3As shown, the feeding wheel 4 has multiple wire grooves 401. One end of the feeding wheel 4 passes through the fixed frame 3 and is fixedly connected to a worm gear 402. A worm 403 is meshed and driven on one side of the worm gear 402. The worm 403 is rotatably connected to the fixed frame 3. A driven wheel 404 is fixedly connected to the bottom end of the worm 403. The driven wheel 404 meshes and drives the driving wheel 202. The conveyor belt 2 drives the electrical switch to the position to be welded. At this time, the conveyor belt 2 drives the connected driving wheel 202 to rotate, so that the driving wheel 202 can drive the worm 403 connected to the driven wheel 404 to rotate, so that the worm 403 can drive the feeding wheel 4 connected to the worm gear 402 to rotate.

[0033] like Figure 4 As shown, the unloading rack 5 has a hollow structure. Multiple wires are placed inside the unloading rack 5. A pressing plate 501 is slidably fitted on the inner wall of the unloading rack 5. A spring 502 is fixedly connected to one end of the pressing plate 501. The other end of the spring 502 is fixedly connected to the inner wall of the unloading rack 5. One end of the unloading rack 5 is slidably fitted to the outer wall of the loading wheel 4.

[0034] like Figure 5 As shown, two guide rods 601 are fixedly connected to both ends of the upper side of the wire bending seat 6. The guide rods 601 are slidably connected to the fixing frame 3. Tension springs A602 are fixedly connected to both ends of the wire bending seat 6. The other end of the tension springs A602 is fixedly connected to the fixing frame 3.

[0035] By setting up the feeding wheel 4 and the wire bending seat 6, the wire is bent in the middle and straight at both ends. When welding to the electrical switch, this structure not only increases the contact area and mechanical strength, but also more effectively disperses heat, facilitates automated welding, reduces offset and misalignment, optimizes spatial layout, improves welding efficiency, and enhances the effect of the protective gas, thereby improving welding quality, switch performance and production efficiency.

[0036] like Figure 6As shown, the transmission mechanism 7 includes a universal joint 701, which is rotatably connected to the fixed frame 3. A pressing rod 702 is fixedly connected to one end of the universal joint 701, and the pressing rod 702 slides in contact with the upper surface of the wire bending seat 6. Multiple transmission teeth 703 are rotatably connected to the inner wall of the other end of the universal joint 701 in a ring structure. A tension spring B704 is fixedly connected to one end of each transmission tooth 703, and the other end of the tension spring B704 is fixedly connected to the inner wall of the universal joint 701. A gear sleeve 705 is rotatably connected to the outer wall of the universal joint 701 near the transmission teeth 703. Multiple tooth grooves are formed on the inner wall of the gear sleeve 705, and these grooves engage with the transmission teeth 703 for transmission. The tension spring B704 enables unidirectional transmission of the transmission teeth 703. The gear sleeve 705 drives the universal joint 701 connected to the transmission gear 703 to rotate, which in turn drives the extrusion rod 702 to rotate. At this time, the extrusion rod 702 will contact and extrude the wire bending seat 6, causing the wire bending seat 6 to move down and cooperate with the feeding wheel 4 to bend the wire.

[0037] like Figure 7 As shown, a motor A801 ​​is fixedly connected to one end of the rotating frame 8, passing through the fixed frame 3. The motor A801 ​​is fixedly connected to the fixed frame 3. A sector gear 802 is fixedly connected to the outer wall of one end of the rotating frame 8, and the sector gear 802 meshes with the gear sleeve 705 for transmission. The rotating frame 8 is driven to rotate by the motor A801, at which time the sector gear 802 on the rotating frame 8 will mesh with the gear sleeve 705.

[0038] like Figure 8 As shown, the wire clamping mechanism 9 includes an electric actuator A901, which is fixedly connected to the rotating frame 8. An adjusting seat 902 is fixedly connected to the output end of the electric actuator A901. An electric actuator B903 is fixedly connected to the adjusting seat 902. A U-shaped frame 904 is fixedly connected to the output end of the electric actuator B903. An adjusting frame 905 is rotatably connected to the inside of the U-shaped frame 904. One end of the adjusting frame 905 passes through the U-shaped frame 904 and is fixedly connected to a motor B906. The motor B906 is fixedly connected to the U-shaped frame 904.

[0039] An electric actuator C907 is fixedly connected to the adjusting frame 905. Two connecting rods 908 are rotatably connected to the output end of the electric actuator C907. A wire clamp 909 is rotatably connected to the other end of the connecting rod 908. The wire clamp 909 is slidably engaged with the adjusting frame 905. Electric actuator A901 drives two wire clamps 909 to be positioned on both sides of the wire. Then, electric actuator C907 drives the connecting rod 908, causing the connecting rod 908 to move one side of the wire clamps 909. At this time, the two wire clamps 909 can clamp the bent wire. Then, electric actuator B903 drives the adjusting seat 902 to move upward, causing the wire clamps 909 to move the wire out of the wire groove 401. Then, electric actuator A901 drives the bent wire to move. Then, motor A801 ​​drives the connected rotating frame 8 to rotate in the opposite direction, and motor B906 drives the connected adjusting frame 905 to rotate, so that both ends of the wire are located on the lower side. Then, electric actuator A901 drives the wire to move downward and approach the electrical switch.

[0040] Working principle: When it is necessary to solder wires to electrical switches, first place the electrical switch to be soldered into the switch housing placement seat 201, then pull out the pressing plate 501 to place multiple wires into the feeding rack 5. When the pressing plate 501 is released, under the action of the spring 502, the pressing plate 501 presses the wires, so that one of the wires can enter the wire groove 401 on the feeding wheel 4.

[0041] Then, the conveyor belt 2 is used to move the electrical switch to the position to be welded. At this time, the conveyor belt 2 will drive the connected drive wheel 202 to rotate, so that the drive wheel 202 can drive the worm 403 connected to the driven wheel 404 to rotate, so that the worm 403 can drive the feeding wheel 4 connected to the worm wheel 402 to rotate, thereby driving the guide to move upward.

[0042] Then, the motor A801 ​​drives the connected rotating frame 8 to rotate. At this time, the sector gear 802 on the rotating frame 8 will mesh with the gear sleeve 705, thereby driving the universal joint 701 connected to the transmission gear 703 to rotate through the tooth groove in the gear sleeve 705, so that the universal joint 701 drives the connected pressing rod 702 to rotate.

[0043] At this time, the extrusion rod 702 will contact and extrude the wire bending seat 6, causing the wire bending seat 6 to move down and cooperate with the feeding wheel 4 to bend the wire. When the sector gear 802 is not meshing with the gear sleeve 705, the wire bending seat 6 will automatically move up and reset under the action of the tension spring A602.

[0044] Then, using electric actuator A901, two wire clamps 909 are positioned on both sides of the wire. Then, using electric actuator C907, the connecting rod 908 is driven, causing the connecting rod 908 to move one side of the wire clamps 909. At this time, the two wire clamps 909 can clamp onto the bent wire. Then, using electric actuator B903, the adjusting seat 902 is moved upward, causing the wire clamps 909 to move the wire out of the wire groove 401. Then, using electric actuator A901, the bent wire is moved. Then, using motor A801, the connected rotating frame 8 is rotated in the opposite direction, and using motor B906, the connected adjusting frame 905 is rotated, so that both ends of the wire are located on the lower side. Then, using electric actuator A901, the wire is moved downward and close to the electrical switch. Finally, the welding robotic arm 10 is used for welding and fixing.
