Description

Technical Field

[0001] This invention relates to the field of switch assembly, and more particularly to a speed control switch and its assembly equipment. Background Technology

[0002] An electric switch is an electronic component used to control the switching of circuits, and is used to control the interruption or diversion of current in a circuit.

[0003] In the prior art, the invention patent with publication number CN118578119A discloses a switch base pressing device and its usage method, including a machine base, a rotating material tray rotatably provided on the machine base, a jig fixedly connected in an array on the rotating material tray, a pressing component fixedly provided on the machine base, a material storage hole provided on the jig, a limiting tube fixedly provided in the material storage hole, a support rod sliding in the limiting tube, a straight groove provided in the support rod, a T-shaped rod sliding in the straight groove, the T-shaped rod being connected to the limiting tube, and a support spring connected to the T-shaped rod fixedly provided in the straight groove;

[0004] However, when the above device is in use, its capacitor assembly part only applies pressure and shapes the capacitor pins in the vertical direction, which may cause the two pins to be out of parallel before assembly. During subsequent assembly, it is difficult for them to be inserted into the corresponding slots, resulting in a decrease in the yield.

[0005] Furthermore, during assembly, when the suction rod contacts the capacitor, the pressure pin used for applying pressure can only reach the top surface of the pin. Due to the spatial design and layout of the switch housing, the highest point of the rectangular opening of terminal one is lower than the position after the pressure pin is pressed down. Therefore, after a single press, the capacitor pin that needs to be electrically connected to the metal plate cannot be pressed into the bottom of the rectangular opening of the metal plate, and a firm electrical connection cannot be guaranteed. Therefore, a subsequent process of repressing is required. The pressure pin moves down a greater distance during the repressing operation, allowing the capacitor pin to fully enter the rectangular opening. However, this method obviously increases the overall process steps and the complexity of the equipment. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a speed control switch and its assembly equipment. In practical use, this solution simultaneously shapes the horizontal direction of the capacitor pins during the working rotation operation, which improves the accuracy of subsequent assembly and reduces the defect rate compared to existing technologies. In addition, during the capacitor pin pressing operation, stable assembly can be completed with only a single pressing, eliminating the need for a re-pressing process and improving overall efficiency.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

A snap-fit ​​connector is located at the end of the metal plate body near the capacitor body. The snap-fit ​​connector has a V-shaped opening, and a rectangular opening is located at the bottom inner part of the V-shaped opening. One lead of the capacitor body passes through a portion of the terminal component one mounting area and extends into the metal plate mounting area, where it is snapped into the rectangular opening. The other lead of the capacitor body extends to another portion of the terminal component one mounting area. Before installation, the two leads of the capacitor body are parallel; after installation, they are bent closer together, utilizing the elasticity of the leads to improve stability after installation.

[0009] An assembly device for a speed control switch is provided for assembling the aforementioned speed control switch. The device includes a support frame and a rotary table mounted on the upper end of the support frame. Multiple assembly fixtures are mounted circumferentially on the upper end of the rotary table.

[0010] The capacitor loading and assembly area includes a support frame 1 installed on the upper end of the carrier frame. A loading track for loading the capacitor body is installed on one side of the support frame 1. A transfer mechanism, a rotation mechanism and a pressing mechanism are installed on the carrier frame. The transfer mechanism is used to transfer the capacitor body from the loading track to the rotation mechanism, and to transfer the rotated capacitor body from the rotation mechanism to the pressing mechanism.

[0011] The indexing mechanism includes a support frame four, on which a rotating seat is mounted. The upper end of the rotating seat has a placement slot and two strip-shaped openings. Each strip-shaped opening contains two relatively moving pressure plates. The pressure plates are temperature-conducting plates and contain heating wires. The upper end of the support frame four is equipped with a traction component for pulling multiple pressure plates to move. When the rotating seat performs an indexing operation, each pair of mating pressure plates will first move relative to each other and then move away from each other, thereby achieving the horizontal shaping of the capacitor body pins.

[0012] Preferably, the traction assembly includes a connecting plate fixedly connected to the side wall of the rotating seat. The connecting plate has a strip-shaped opening, and four sliders are slidably connected inside the strip-shaped opening. The four sliders are fixedly connected to corresponding pressure plates. The lower ends of the four sliders are all fixedly connected to inclined bars, and each of the four inclined bars has an inclined guide groove. A U-shaped frame is provided below the connecting plate. Multiple round rods are fixedly connected between the inner walls of the U-shaped frame. The multiple round rods pass through the corresponding inclined guide grooves and are slidably connected. L-shaped guide plates are fixedly connected to both sides of the U-shaped frame.

Multiple horizontal plates are fixedly connected to one side of the U-shaped frame and the connecting plate. Each pair of mating horizontal plates is elastically connected by a return spring. A connecting frame is fixedly connected to the lower end of the U-shaped frame. A magnetic strip is fixedly connected to the lower end of the connecting frame.

[0014] Preferably, the transfer mechanism includes a support frame two fixedly connected to the upper end of the carrier frame, a cylinder two installed on one side of the support frame two, a connecting seat fixedly connected to the telescopic end of the cylinder two, a first adsorption station and a second adsorption station provided on the connecting seat, the first adsorption station including a cylinder four installed on the upper end of the connecting seat, a suction rod two fixedly connected to the telescopic end of the cylinder four, the second adsorption station including a cylinder five installed on the upper end of the connecting seat, a suction rod one fixedly connected to the telescopic end of the cylinder five, and a pressure seat fixedly connected to the suction rod one.

[0015] Preferably, the pressing mechanism includes a first pressing needle and a second pressing needle fixedly connected to the lower end of the pressure seat. Both the first pressing needle and the second pressing needle are provided with abutting components on opposite sides. The abutting components include guide rods fixedly connected to the first pressing needle or the second pressing needle. An L-shaped pressure strip is provided through the other end of each guide rod. The L-shaped pressure strip is elastically connected to the first pressing needle or the second pressing needle through a return spring. An inclined surface is provided on the outer side of the corner of the L-shaped pressure strip.

[0016] Preferably, two L-shaped protective rods for supporting the capacitor body pins are symmetrically fixedly connected to one side of the suction rod.

[0017] Preferably, the lower end of the first pressure needle is provided with a groove, and a pressure bar that can slide up and down is provided in the groove. An electromagnet is fixedly connected to the top of the groove, and the electromagnet and the pressure bar are elastically connected by multiple return springs.

[0018] Preferably, the pressure bar is magnetic, and when the electromagnet is energized, the adjacent surfaces of the pressure bar repel each other due to their similar polarities. Conductive plates are installed on both the front and rear sides of the first pressure pin, and a storage battery is embedded inside the first pressure pin. The positive terminal of the storage battery is electrically connected to the rear conductive plate, and the negative terminal of the storage battery, the electromagnet, and the front conductive plate are electrically connected in sequence.

[0019] Preferably, it also includes a limiting mechanism, which includes a support frame three installed on the upper end of the support frame, a cylinder three installed on the support frame three, and a limiting clamp plate fixedly connected to the telescopic end of the cylinder three. Two through holes are provided on the limiting clamp plate for the first pressure needle and the second pressure needle to pass through.

[0020] Compared with the prior art, the beneficial effects of this invention are as follows:

[0021] 1. After installation, the capacitor leads are bent close together, utilizing the elasticity of the leads and the rectangular opening for clamping. Combined with the tilted shape after installation, this effectively improves the connection stability between the capacitor and the metal plate, ensuring the reliability of the speed control switch.

[0022] 2. The vertical shaping mechanism, used in conjunction with a cylinder, can complete vertical shaping during capacitor loading intervals; the indexing mechanism automatically performs horizontal shaping during indexing, using heating to make shaping easier and ensuring sufficient cooling time for the leads, without affecting subsequent transport.

[0023] 3. The pressing mechanism is equipped with a stop component, which makes the pins slightly bent before pressing in, reducing capacitor pressure damage and avoiding pin damage that affects the quality of the finished product; the L-shaped protective rod transfers the bending force point and enhances the structural strength.

[0024] 4. The use of the press-fitting mechanism eliminates the need for re-pressing compared to existing technologies, optimizing the overall assembly process and improving overall efficiency. Attached Figure Description

Detailed Implementation

[0043] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0044] Reference Figures 1-5 A speed control switch includes a housing body 1. The inner side of the housing body 1 is provided with a metal plate mounting area 11, a capacitor mounting area 12, a terminal component one mounting area 13, a terminal component two mounting area 14 and a metal rod mounting area 15. The lower side of the housing body 1 is provided with a button mounting area 16. It also includes an upper housing (not shown). The upper housing and the housing body 1 can form an integral switch housing.

[0045] Among them, a metal plate body 111 is riveted to the metal plate mounting area 11, a capacitor body 121 is installed in the capacitor mounting area 12, a terminal component body 131 is installed in the terminal component one mounting area 13, a terminal component two body 141 is installed in the terminal component two mounting area 14, a metal rod body 151 is installed in the metal rod mounting area 15, and a spring and a button body 161 are installed in the button mounting area 16.

[0046] The metal plate body 111 has a snap-fit ​​connector 1111 on one end near the capacitor body 121. The snap-fit ​​connector 1111 has a V-shaped opening 1112 and a rectangular opening 1113 at the bottom of the V-shaped opening 1112. One of the leads of the capacitor body 121 passes through a part of the terminal mounting area 13 and extends into the metal plate mounting area 11, where it is snapped into the rectangular opening 1113. The other lead of the capacitor body 121 extends into another part of the terminal mounting area 13. The two leads of the capacitor body 121 are parallel before installation and are bent closer together after installation. The elasticity of the leads themselves improves the stability after installation. The snap-fit ​​of the rectangular opening 1113 and the tilted shape after installation improve the connection stability after assembly.

[0047] Reference Figure 6 The present invention also discloses an assembly equipment for a speed control switch, used for assembling the speed control switch mentioned above, including a support frame 2 and a rotary table 3 installed on the upper end of the support frame 2. Multiple assembly fixtures 31 are installed circumferentially on the upper end of the rotary table 3. The rotary table 3 is circumferentially arranged with a button feeding assembly area 21, a spring feeding assembly area 22, a housing feeding assembly area 23, a metal plate feeding assembly area 24, a capacitor feeding assembly area 25, a terminal component one feeding assembly area 26, a terminal component two feeding assembly area 27, a metal rod feeding assembly area 28, and a discharge area 29. The end of the discharge area 29 is provided with a cover mounting area.

[0048] Furthermore, the button body 161 is loaded onto the assembly fixture 31 at the button loading and assembly area 21. After the rotary table 3 rotates, the spring body is assembled in the spring loading and assembly area 22. Then, after the rotary table 3 rotates, the housing body 1 is assembled in the housing loading and assembly area 23. Subsequently, after the rotary table 3 rotates, the metal plate body 111 is assembled in the metal plate loading and assembly area 24. Next, after the rotary table 3 rotates, the capacitor body 121 is assembled in the capacitor loading and assembly area 25. Finally, after the rotary table 3 rotates, the terminal component is loaded. The main body 131 of terminal component one is assembled at assembly area 26. Then, after the rotary table 3 rotates, the main body 141 of terminal component two is assembled at terminal component two loading assembly area 27. After the rotary table 3 rotates, the main body 151 of metal rod is assembled at metal rod loading assembly area 28. Except for capacitor loading assembly area 25, the above assembly points are all existing technologies. Please refer to the relevant part of the invention patent with publication number CN118578119A. Finally, it is discharged from the discharge area 29 and enters the subsequent top cover installation area for assembly.

[0049] Reference Figures 7-10 The capacitor loading and assembly area 25 includes a support frame 2501 installed on the upper end of the support frame 2. A loading track 2502 for loading the capacitor body 121 is installed on one side of the support frame 2501. A transfer mechanism, a rotation mechanism and a pressing mechanism are installed on the support frame 2. The transfer mechanism is used to transfer the capacitor body 121 from the loading track 2502 to the rotation mechanism, and to transfer the capacitor body 121 after rotation from the rotation mechanism to the pressing mechanism.

[0050] Reference Figures 7-8 It also includes a vertical shaping mechanism, which includes a cylinder 2503 installed on the upper end of the support frame 2501. The telescopic end of the cylinder 2503 is fixedly connected to a vertical pressure plate 2504. When the capacitor body 121 moves intermittently on the feeding track 2502, it can work in conjunction with the use of the cylinder 2503 to move the vertical pressure plate 2504 down and then up, thus completing the vertical shaping of the capacitor body 121.

[0051] Reference Figures 7-8The transfer mechanism includes a support frame 2505 fixedly connected to the upper end of the carrier frame 2. A cylinder 2506 is installed on one side of the support frame 2505. A connecting seat 2507 is fixedly connected to the telescopic end of the cylinder 2506. A first adsorption station and a second adsorption station are provided on the connecting seat 2507. The first adsorption station includes a cylinder 2512 installed on the upper end of the connecting seat 2507. A suction rod 2514 is fixedly connected to the telescopic end of the cylinder 2512. The second adsorption station includes a cylinder 2513 installed on the upper end of the connecting seat 2507. A suction rod 2510 is fixedly connected to the telescopic end of the cylinder 2513. A pressure seat 2519 is fixedly connected to the suction rod 2510. The first adsorption station is used to transfer the capacitor from the loading track 2502 to the rotating seat 2516. The second adsorption station can rotate the capacitor from the rotating seat 2516 to the assembly fixture 31 and perform press-fitting.

[0052] Reference Figures 8-9 , Figures 11-13 The indexing mechanism includes a support frame 2515, on which a rotating seat 2516 is mounted. The upper end of the rotating seat 2516 has a placement groove 2517 and two strip-shaped openings 2518. Each strip-shaped opening 2518 contains two relatively movable pressure plates 2526. The pressure plates 2526 are temperature-conducting plates and have heating wires inside. During use, the heating wires can work to heat the pressure plates 2526. In this way, during subsequent shaping operations, the heated pressure plates 2526 can slightly dye the leads, making the shaping work easier.

[0053] The upper end of the support frame 2515 is equipped with a traction component for moving multiple pressure plates 2526. When the rotating seat 2516 performs a rotation operation, each pair of mating pressure plates 2526 will first move relative to each other and then move away from each other, thereby shaping the horizontal direction of the capacitor body 121 pins. The traction component includes a connecting plate 2524 fixedly connected to the side wall of the rotating seat 2516. The connecting plate 2524 has a strip-shaped opening 2525, and four sliders are slidably connected in the strip-shaped opening 2525. The four sliders are fixedly connected to the corresponding pressure plates 2526. The lower ends of the four sliders are all fixedly connected to inclined bars 2527, and each of the four inclined bars 2527 has an inclined guide groove 2533. A loop frame 2528 is provided below the connecting plate 2524, and multiple round rods 25 are fixedly connected between the inner walls of the loop frame 2528. 32. Multiple round rods 2532 pass through corresponding inclined guide grooves 2533 and are slidably connected. Both sides of the U-shaped frame 2528 are fixedly connected to L-shaped guide plates 2529. The vertical parts of the two guide plates 2529 are in contact with the connecting plate 2524 and are slidably connected. Multiple horizontal plates 2530 are fixedly connected to one side of the U-shaped frame 2528 and the connecting plate 2524. Each pair of mating horizontal plates 2530 are elastically connected by a return spring 2531. The lower end of the U-shaped frame 2528 is fixedly connected to a connecting frame 2534. The lower end of the connecting frame 2534 is fixedly connected to a magnetic strip 2544. The upper end of the support frame 2515 is fixedly connected to a strong magnetic block 2523. The adjacent surfaces of the strong magnetic block 2523 and the magnetic strip 2544 are attracted by opposite polarities. When the magnetic strip 2544 approaches the strong magnetic block 2523, the magnetic strip 2544 will move downward under the magnetic force.

[0054] Furthermore, the initial position of the aforementioned rotating base 2516 is the position where the capacitor is to be placed. Its two strip-shaped openings 2518 are located at the front of the rotating base 2516. After the capacitor body 121 is placed, the rotating base 2516 rotates 90°. Subsequently, as the capacitor body 121 is transferred to the next working position, the rotating base 2516 rotates back to the initial position, and so on. During the rotation of the rotating base 2516, the magnetic strip 2544 on it will first approach the strong magnetic block 2523, and then move away from the strong magnetic block 2523. During this process, with the use of the return spring 2531, the magnetic strip 2544, the loop frame 2528, the guide plate 2529, and the multiple round rods 2532 can form a... The entire assembly moves downwards first, then upwards. During the downward movement of multiple round rods 2532, multiple pressure plates 2526 can move with the help of the inclined guide grooves 2533 inside the inclined bars 2527. Specifically, every two pressure plates 2526 located on both sides of the capacitor pins will first approach the capacitor pins to achieve pressure shaping. Subsequently, during the upward movement of multiple round rods 2532, the pressure plates 2526 will move back and away from the capacitor pins. Using this method, pressure shaping can be automatically performed during the transposition operation. During pressure application, high temperature is used to make shaping simpler. After shaping is completed, the pressure plates 2526 leave, ensuring that the capacitor pins have sufficient time to dissipate heat and cool down, while not affecting subsequent transfer operations.

[0055] Reference Figure 10 , Figure 10-17 The pressing mechanism includes a first pressing pin 2520 and a second pressing pin 2521 fixedly connected to the lower end of the pressing base 2519. The first pressing pin 2520 is used to press the long pin, and the second pressing pin 2521 is used to press the short pin. The opposing sides of the first pressing pin 2520 and the second pressing pin 2521 are provided with abutting components. The abutting components include guide rods 2539 fixedly connected to the first pressing pin 2520 or the second pressing pin 2521. The other end of each guide rod 2539 is provided with an L-shaped pressing strip 2536. The L-shaped pressing strip 2536 is elastically connected to the first pressing pin 2520 or the second pressing pin 2521 through a second return spring 2538. An inclined surface 2537 is provided on the outer side of the corner of the L-shaped pressing strip 2536. Two L-shaped protective rods 2522 for supporting the pins of the capacitor body 121 are symmetrically fixedly connected to one side of the suction rod 2510.

[0056] By employing abutment components, when the capacitor body 121 is placed into the housing body 1, during the downward movement, the two abutment components first contact the side wall of the corresponding terminal mounting area 13, causing the two L-shaped pressure bars 2536 to move closer to the corresponding pins, thus slightly bending the two pins inward. Simultaneously, the downward movement of the first pressure pin 2520 and the second pressure pin 2521 presses the slightly bent pins into the corresponding area (the corresponding pressing area is not directly opposite the capacitor pins; for the capacitor pins to be fully assembled, they must be slightly bent). The slightly bent pins possess a certain preload. This improves stability after installation. Compared to relying directly on pressure and the side wall guidance of the pressing area, the method of bending before pressing reduces the pressure damage to the capacitor and avoids excessive damage to the pins, which would affect the quality of the finished product. In addition, the use of the L-shaped protective rod 2522 can transfer the bending force point to the contact point with the L-shaped protective rod 2522 when the pin is bent, avoiding the force point being at the contact point between the pin and the capacitor body 121 (where there is a geometric change at the connection between the pin and the body, causing stress concentration in this area. According to the mechanics of materials, stress concentration will make the local stress much higher than the average stress, resulting in lower structural strength).

[0057] The first pressure needle 2520 has a groove 2540 at its lower end. A pressure bar 2543 that can slide up and down is provided in the groove 2540. An electromagnet 2541 is fixedly connected to the top of the groove 2540. The electromagnet 2541 and the pressure bar 2543 are elastically connected by multiple return springs 2542. The pressure bar 2543 is magnetic. When the electromagnet 2541 is energized, it and the adjacent surfaces of the pressure bar 2543 are like-pole and repel each other. Conductive plates 2535 are installed on both the front and rear sides of the first pressure needle 2520. A storage battery is embedded inside the first pressure needle 2520. The positive terminal of the storage battery is electrically connected to the rear conductive plate 2535. The negative terminal of the storage battery, the electromagnet 2541 and the front conductive plate 2535 are electrically connected in sequence.

[0058] After the first pressure pin 2520 and the second pressure pin 2521 are fully pressurized, the two conductive pieces 2535 of the first pressure pin 2520 will finally contact the inside of the V-shaped opening 1112 of the metal plate body 111. At this time, the metal plate body 111 is equivalent to a conductor, which energizes the circuit of the electromagnet 2541. After the electromagnet 2541 is energized, it will exert a repulsive force on the pressure bar 2543, causing it to move downward, achieving a similar effect to the repressurization in the prior art, so that the pins of the capacitor body 121 are fully pressed into the rectangular opening 1113, completing the overall assembly. Compared with the prior art, this solution optimizes the overall process. The repressurization operation is performed simultaneously during the first pressurization, which improves the overall efficiency.

[0059] Reference Figures 7-8It also includes a limiting mechanism, which includes a support frame 2508 installed on the upper end of the support frame 2. A cylinder 2509 is installed on the support frame 2508. The telescopic end of the cylinder 2509 is fixedly connected to a limiting clamping plate 2511. The limiting clamping plate 2511 has two through holes for the first pressing needle 2520 and the second pressing needle 2521 to pass through. Before the pressing mechanism is operated, the limiting mechanism is operated, causing the limiting clamping plate 2511 to move down and limit the housing body 1 to ensure its stability during pressing.

[0060] The working principle of this device is as follows:

[0061] The button body 161 is fed into the assembly fixture 31 in the button feeding and assembly area 21. After the rotary table 3 rotates, the spring body is assembled in the spring feeding and assembly area 22. After rotating again, the housing body 1 is assembled in the housing feeding and assembly area 23. Then, after rotating, the metal plate body 111 is assembled in the metal plate feeding and assembly area 24. After rotating, the capacitor body 121 is assembled in the capacitor feeding and assembly area 25. Then, the terminal component 1 body 131 is assembled in the terminal component 1 feeding and assembly area 26, the terminal component 2 body 141 is assembled in the terminal component 2 feeding and assembly area 27, and the metal rod body 151 is assembled in the metal rod feeding and assembly area 28. Finally, it is discharged from the discharge area 29 and enters the top cover mounting area for assembly.

[0062] The working process of capacitor loading and assembly area 25 is as follows:

[0063] When the capacitor body 121 moves intermittently on the feeding track 2502, cylinder 1 2503 drives the vertical pressure plate 2504 to move down and then up, completing the vertical shaping of the capacitor body 121. In conjunction with the use of cylinder 2 2506, cylinder 4 2512 drives suction rod 2514 to transfer the capacitor from the feeding track 2502 to the rotating seat 2516. Cylinder 5 2513 drives suction rod 1 2510 to transfer the capacitor from the rotating seat 2516 to the assembly fixture 31.

[0064] Furthermore, the initial position of the rotating seat 2516 is the position where the capacitor is to be placed. After the capacitor body 121 is placed, it rotates 90° and then rotates back to the initial position after transferring the capacitor body 121. During the rotation, the magnetic strip 2544 first approaches the strong magnetic block 2523 and then moves away. With the help of the reset spring 2531, the whole formed by the loop frame 2528 and so on moves down and then up. When the round rod 2532 moves down, the inclined guide groove 2533 allows the pressure plate 2526 to first approach the capacitor pin and apply pressure to shape it. When it moves up, the pressure plate 2526 moves back away from the capacitor pin.

[0065] Before pressing, cylinder 2509 drives the limiting clamp 2511 to move down, limiting the housing body 1 and ensuring pressing stability;

[0066] During the pressing process, the lower end of the pressing base 2519 of the pressing mechanism is fixed with the first pressing pin 2520 and the second pressing pin 2521, which apply pressure to the long pin and the short pin respectively. During the downward movement, the abutment component first contacts the side wall of the terminal mounting area 13, so that the L-shaped pressing strip 2536 is close to the pin, causing the pin to bend slightly inward. At the same time, the first pressing pin 2520 and the second pressing pin 2521 move down to press the pin into the corresponding area. After full pressing, the two conductive pieces 2535 of the first pressing pin 2520 contact the V-shaped opening 1112 of the metal plate body 111, so that the electromagnet 2541 circuit is energized. The electromagnet 2541 gives the pressing strip 2543 a repulsive force to move it down, so that the pin of the capacitor body 121 is fully pressed into the rectangular opening 1113.

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 inventive concept of the present invention, should be covered within the scope of protection of the present invention.
