Description

Technical Field

[0001] This utility model relates to the field of metal push button switch assembly technology, specifically to an automatic assembly device for metal push button assemblies. Background Technology

[0002] A metal push-button switch is a convenient and easy-to-use switch, typically composed of a base, a moving contact, a tension spring, and a stationary contact. These components work together closely to achieve the core function of the switch. In assembling a metal push-button switch, firstly, one end of the tension spring is attached to the moving contact to form the moving contact assembly. Then, the base and other parts, including the stationary contact, are assembled to form the base assembly. Finally, the two prongs of the moving contact are inserted into the slots on both sides of the base assembly, while the other end of the tension spring is attached to the base assembly, thus assembling the moving contact assembly and base assembly into the desired metal push-button assembly. The tension spring plays a crucial role in this process, ensuring that the moving contact prongs remain engaged with the base assembly, thereby ensuring a stable and reliable assembly structure that is not easily loosened.

[0003] However, current installation methods mostly rely on manual operation, which is inefficient and easily affected by fatigue, mood, and other factors, leading to uncontrollable assembly quality. In particular, the tension springs are small and elastic; even slight carelessness can cause them to detach or be improperly installed, affecting the assembly structure of the moving plate assembly and the base assembly. This directly results in a large number of scrapped products and increases production costs.

[0004] In view of the shortcomings of the existing technology, it is necessary to develop an automatic assembly device for metal button assemblies. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] This invention provides an automatic assembly device for metal button assemblies, which can at least solve the technical problem of how to improve production efficiency and ensure the consistency and stability of assembly quality.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic assembly device for metal button assemblies, comprising:

[0009] frame;

[0010] The first feeding mechanism and the second feeding mechanism are both located on the frame. The first feeding mechanism is used to transfer the moving piece assembly one by one to the feeding station, and the second feeding mechanism is used to transfer the base assembly one by one to the assembly station.

[0011] The transfer mechanism is mounted on the frame and is connected to the flipping mechanism via a transmission. The transfer mechanism is used to drive the flipping mechanism to reciprocate between the loading station and the assembly station. The flipping mechanism is used to grab the moving plate and tension spring of the moving plate assembly at the loading station, and to flip the moving plate to the position opposite to the slot of the base assembly at the assembly station.

[0012] The pressing mechanism, located on the flipping mechanism, is used to press the tension spring and base assembly at the assembly station to hook the tension spring onto the base assembly and insert the pin of the moving piece into the corresponding slot.

[0017] In a further configuration, the aforementioned first feeding mechanism also includes a magnetic suction component and a magnetic suction drive component. The magnetic suction component is positioned opposite to the feeding station and is used to attract or release the tension spring of the feeding station so that the tension spring of the feeding station is perpendicularly distributed to the moving plate. The magnetic suction drive component is mounted on the frame and is connected to the magnetic suction component for transmission. The magnetic suction drive component is used to drive the magnetic suction component to move toward or away from the feeding station.

[0018] Further, the aforementioned second feeding mechanism includes a second translation drive, a tooling, and a workpiece positioning assembly. The second translation drive is mounted on the frame and is connected to the tooling and workpiece positioning assembly in a transmission manner. The second translation drive is used to drive the tooling and workpiece positioning assembly to move toward or away from the assembly station. The tooling is provided with a limiting groove for accommodating and limiting the base assembly. The workpiece positioning assembly is used to fix the base assembly in the limiting groove.

[0019] Further, the aforementioned tooling includes a limiting plate, a sliding block, and an elastic element. The limiting plate is provided with a limiting groove and a sliding groove communicating with the limiting groove. The sliding block is slidably disposed in the sliding groove. One end of the elastic element is connected to the side wall of the sliding groove facing away from the limiting groove, and the other end is connected to the sliding block. The elastic element has an elastic force that drives the sliding block to slide toward the limiting groove. The sliding block is used to abut against the base assembly in the limiting groove. The sliding block is provided with a clearance groove for the insertion of the tension spring portion.

[0020] In a further configuration, the aforementioned workpiece positioning assembly includes a pressure arm and a pressure arm drive assembly. The bottom of the limiting groove is provided with a through hole for the pressure arm to pass through. There is one or two pressure arms. The pressure arm drive assembly is located on the output end of the second translation drive component and is connected to one or two pressure arms in a transmission manner. The pressure arm drive assembly is used to drive the pressure arm to insert into or pull out of the limiting groove, and to drive the pressure arm to move toward or away from the base assembly in the limiting groove, so as to fix or loosen the base assembly.

[0021] Furthermore, the aforementioned tooling is located at the output end of the second translation drive component;

[0022] The second feeding mechanism also includes a tooling positioning component, which is installed on the output end of the second translation drive component and is used to fix the tooling on the output end of the second translation drive component.

[0023] Further, the output end of the aforementioned second translation drive is provided with a mounting plate, the mounting plate is provided with a receiving groove and a sliding channel communicating with the receiving groove, the receiving groove being used to receive tooling;

[0024] The tooling positioning assembly includes a cam and a cam drive. The cam is slidably disposed in the sliding channel and is used to abut against the tooling in the receiving groove. The cam drive is fixed on the output end of the second translation drive and is connected to the cam drive.

[0025] (III) Beneficial Effects

[0026] Compared with the prior art, the automatic assembly device for metal button assemblies provided by this utility model has the following advantages:

[0027] When using the automatic assembly device for metal button assemblies provided by this utility model, firstly, the first feeding mechanism transfers the assembled moving plate assemblies one by one to the feeding station, while the second feeding mechanism transfers the assembled base assemblies one by one to the assembly station. Then, the flipping mechanism grabs the moving plate and tension spring of the moving plate assembly at the feeding station. Next, the transfer mechanism drives the flipping mechanism to move from the feeding station to the assembly station, thereby moving the moving plate assembly to the assembly station. Subsequently, the flipping mechanism releases the tension spring, and the pressing mechanism hooks the free end of the tension spring onto the base assembly. Finally, the flipping mechanism flips the moving plate so that the two prongs of the moving plate are aligned with the slots on both sides of the base assembly. Then, the flipping mechanism releases the moving plate. At this time, the moving plate moves into the slot under the action of the tension spring, inserting the two prongs into the two slots respectively, thereby assembling the moving plate assembly and the base assembly into the required metal button assembly. As can be seen, this utility model achieves automatic feeding of the moving plate assembly and the base assembly through the first feeding mechanism and the second feeding mechanism, respectively. The moving plate and the tension spring are grasped, flipped and positioned by the transfer mechanism and the flipping mechanism. The tension spring and the base assembly are automatically hooked together by the pressing mechanism. At the same time, the moving plate and the base assembly are automatically inserted, thereby realizing the automated assembly of the metal button assembly, replacing manual labor, effectively improving production efficiency, reducing labor costs, and ensuring the consistency and stability of assembly quality.

[0042] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0043] This invention provides an automatic assembly device for metal button assemblies, which addresses the problem of improving production efficiency and ensuring the consistency and stability of assembly quality.

[0044] See Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a perspective view of the automatic assembly device for the metal button assembly in the embodiment. Figure 2 for Figure 1 Enlarged diagram of point A in the middle. Figure 3 for Figure 1 The enlarged schematic diagram at point B shows that the automatic assembly device for the metal button assembly includes a frame 1, a first feeding mechanism 2, a second feeding mechanism 3, a transfer mechanism 4, a flipping mechanism 5, and a pressing mechanism 6.

[0045] The first feeding mechanism 2 and the second feeding mechanism 3 are both mounted on the frame 1. The first feeding mechanism 2 is used to transfer the moving piece assembly 7 one by one to the feeding station 11. The second feeding mechanism 3 is used to transfer the base assembly 8 one by one to the assembly station 12.

[0046] The transfer mechanism 4 is mounted on the frame 1 and is connected to the flipping mechanism 5 via a transmission. The transfer mechanism 4 drives the flipping mechanism 5 to reciprocate between the loading station 11 and the assembly station 12. The flipping mechanism 5 is used to grab the moving piece 71 and tension spring 72 of the moving piece assembly 7 at the loading station 11, and to flip the moving piece 71 to be opposite to the slot 81 of the base assembly 8 at the assembly station 12.

[0047] The pressing mechanism 6 is mounted on the flipping mechanism 5. The pressing mechanism 6 is used to press the tension spring 72 and the base assembly 8 of the assembly station 12 to hook the tension spring 72 onto the base assembly 8 and insert the pin 711 of the moving piece 71 into the corresponding slot 81.

[0048] When using the automatic assembly device for metal button components according to the above technical solution, firstly, the first feeding mechanism 2 transfers the assembled moving piece assemblies 7 one by one to the feeding station 11, while the second feeding mechanism 3 transfers the assembled base assemblies 8 one by one to the assembly station 12. Then, the flipping mechanism 5 grabs the moving piece 71 and the tension spring 72 of the moving piece assembly 7 at the feeding station 11. Next, the transfer mechanism 4 drives the flipping mechanism 5 to move from the feeding station 11 to the assembly station 12, thereby moving the moving piece assembly 7 to the assembly station 12. Subsequently, the flipping mechanism 5 releases the tension spring 72, and the pressing mechanism 6 attaches the free end of the tension spring 72 to the base assembly 8. Finally, the flipping mechanism 5 flips the movable piece 71 so that the two prongs 711 of the movable piece 71 are aligned with the slots 81 on both sides of the base assembly 8. Then, the flipping mechanism 5 releases the movable piece 71. At this time, the movable piece 71 moves towards the slots 81 under the action of the tension spring 72, inserting the two prongs 711 into the two slots 81 respectively, thereby assembling the movable piece assembly 7 and the base assembly 8 into the required metal button assembly. It can be seen that this utility model realizes the automatic feeding of the movable piece assembly 7 and the base assembly 8 through the first feeding mechanism 2 and the second feeding mechanism 3 respectively. The transfer mechanism 4 and the flipping mechanism 5 cooperate to complete the gripping, flipping and positioning of the movable piece 71 and the tension spring 72. Combined with the pressing mechanism 6, the tension spring 72 and the base assembly 8 are automatically hooked together, and the movable piece 71 and the base assembly 8 are automatically inserted. Thus, the automated assembly of the metal button assembly is realized, replacing manual labor, effectively improving production efficiency, reducing labor costs, and ensuring the consistency and stability of assembly quality.

[0049] The aforementioned transfer mechanism 4 can use an existing two-axis drive mechanism or a three-axis drive mechanism to drive the flipping mechanism 5 to move horizontally and vertically, so as to realize the reciprocating motion of the flipping mechanism 5 between the loading station 11 and the assembly station 12.

[0050] See Figure 1 and Figure 2 As shown, in one embodiment of the first feeding mechanism 2, the first feeding mechanism 2 includes a first chuck 21, a flipping drive 22, and a first translation drive 23. The first chuck 21 is used to clamp or release the moving pieces 71. The flipping drive 22 and the first translation drive 23 are connected, one of which is mounted on the frame 1, and the other is connected to the first chuck 21. The flipping drive 22 and the first translation drive 23 are combined to drive the first chuck 21 to reciprocate between a first position and a second position. In the first position, the first chuck 21 is opposite to the turntable, which is used to supply the moving pieces 7 one by one. In the second position, the moving pieces 7 on the first chuck 21 are located at the feeding station 11, and the moving pieces 71 are vertically distributed. Thus, the first feeding mechanism 2, through the cooperation of the flipping drive 22 and the first translation drive 23, enables the first chuck 21 to accurately grasp the moving piece 71 of the assembled moving piece assembly 7 on the turntable and accurately transfer it to the feeding station 11. The moving piece 71 is vertically distributed at the feeding station 11, which facilitates the subsequent transfer mechanism 4 and the flipping mechanism 5 to grasp and assemble the moving piece 71, thereby improving the accuracy and efficiency of assembly.

[0051] The first translation drive 23 can be a linear drive mechanism such as an existing telescopic cylinder or a motor-screw-nut linear module, the flip drive 22 can be a rotary drive mechanism such as an existing rotary cylinder or rotary motor, and the first chuck 21 can be a existing clamping cylinder 3322. In this embodiment, the first translation drive 23 is mounted on the frame 1, and the output end of the flip drive 22 is connected to the first chuck 21, but the reverse is also possible.

[0052] See Figure 1 As shown, multiple turntable fixtures 32 are distributed on the turntable, which are used to accommodate and position the moving piece assembly 7.

[0053] See Figure 1 , Figure 2 and Figure 4 As shown, Figure 4This is a partial structural diagram of the second feeding mechanism, flipping mechanism, and pressing mechanism in the embodiments. In one embodiment of the flipping mechanism 5 and the pressing mechanism 6, the flipping mechanism 5 includes a second chuck 51, a third chuck 52, and a rotary drive member 53. The second chuck 51 is used to clamp or release the moving piece 71. The third chuck 52 is used to clamp or release the tension spring 72. The rotary drive member 53 is mounted on the output end of the transfer mechanism 4 by means of screwing or welding. The output end of the rotary drive member 53 is fixedly connected to the second chuck 51 and the third chuck 52 by means of screwing or welding. The rotary drive member 53 is used to drive the second chuck 51 and the third chuck 52 to flip. The pressing mechanism 6 includes a pressing block 61 and a pressing block drive member 62. The pressing block drive member 62 is mounted on the output end of the rotary drive member 53 by means of screwing or welding and is connected to the pressing block 61 in a driving manner. The free end of the pressing block 61 is positioned opposite to the output end of the third chuck 52. The pressure block drive 62 is used to drive the pressure block 61 to move toward or away from the output end of the third chuck 52, so as to press the tension spring 72 and the base assembly 8 at the assembly station 12. Thus, when the first loading mechanism 2 transfers the moving piece assembly 7 to the loading station 11, firstly, the flipping mechanism 5 can grasp the moving piece 71 and the tension spring 72 at the loading station 11 respectively through the second chuck 51 and the third chuck 52; then, when the transfer mechanism 4 drives the flipping mechanism 5 to move from the loading station 11 to the assembly station 12, it causes the moving piece assembly 7 to move accordingly above the base assembly 8; next, the third chuck 52 releases the tension spring 72, and the pressure block drive 62 drives the pressure block 61 toward the output end of the third chuck 52. The second clamp 52 displaces the spring 72, thus attaching the free end of the spring 72 to the base assembly 8. Then, the rotary drive 53 drives the third clamp 52 and its movable piece 71 to rotate horizontally, aligning the two prongs 711 of the movable piece 71 with the slots 81 on either side of the base assembly 8. Finally, the second clamp 51 releases the movable piece 71, which, under the action of the spring 72, moves towards the slots 81, inserting the two prongs 711 into the two slots 81 respectively, thus completing the assembly of the movable piece assembly 7 and the base assembly 8. It can be seen that the flipping mechanism 5, by gripping the spring 72 with the third clamp 52, ensures the spring 72 is in the correct position at the assembly station 12, allowing the pressing mechanism 6 to accurately attach the free end of the spring 72 to the base assembly 8, ensuring reliable attachment. Furthermore, the flipping mechanism 5, through the rotary drive 53 and the second clamp 51, rotates the movable piece 71, ensuring it is correctly aligned and inserted into the slots 81 of the base assembly 8, improving the reliability and stability of the assembly.

[0054] The second chuck 51 and the third chuck 52 can use existing clamping cylinders, the rotary drive 53 can use existing rotary cylinders or rotary motors and other rotary drive mechanisms, and the pressure block drive 62 can use existing telescopic cylinders or motor-screw nut linear modules and other linear drive mechanisms.

[0055] See Figure 1 and Figure 2 As shown, based on the above embodiment, the first feeding mechanism 2 further includes a magnetic suction component 24 and a magnetic suction drive component 25. The magnetic suction component 24 is positioned opposite to the feeding station 11 and is used to attract or release the tension spring 72 of the feeding station 11, so that the tension spring 72 of the feeding station 11 is perpendicularly distributed to the moving plate 71. The magnetic suction drive component 25 is mounted on the frame 1 by means of screwing or welding, and is connected to the magnetic suction component 24 in a transmission manner. The magnetic suction drive component 25 is used to drive the magnetic suction component 24 to move towards or away from the feeding station 11. Thus, the first chuck 21, the flipping drive 22, and the first translation drive 23 work together to transfer the moving piece assembly 7 to the loading station 11. The magnetic drive 25 drives the magnetic suction component 24 to move towards the loading station 11, bringing it closer to the tension spring 72 of the moving piece assembly 7. This attracts the tension spring 72, causing it to flip towards the magnetic suction component 24 and rotate perpendicular to the moving piece 71. Then, the transfer mechanism 4 drives the second chuck 51 and the third chuck 52 to descend towards the loading station 11, respectively gripping the moving piece 71 and the tension spring 72, maintaining their perpendicular distribution for subsequent assembly. It can be seen that the magnetic suction component 24 and the magnetic drive 25 work together to restrict the distribution of the tension spring 72 at the loading station 11, allowing the subsequent flipping mechanism 5 to accurately grip the tension spring 72. This ensures the accurate positioning of the tension spring 72 during subsequent assembly, reducing assembly problems caused by incorrect spring 72 positioning, thereby improving assembly efficiency and quality.

[0056] The aforementioned magnetic drive component 25 can use existing linear drive mechanisms such as telescopic cylinders or motor-screw-nut linear modules, and its output end is connected to the magnetic component 24 by means of screwing or welding. The aforementioned magnetic component 24 can use parts with magnetic attraction capabilities such as electromagnets or magnets.

[0057] See Figure 1 and Figure 3 As shown, in one embodiment of the second loading mechanism 3, the second loading mechanism 3 includes a second translation drive 31, a tooling 32, and a workpiece positioning assembly 33. The second translation drive 31 is mounted on the frame 1 by means of screwing or welding, and is connected to the tooling 32 and the workpiece positioning assembly 33 in a transmission manner. The second translation drive 31 is used to drive the tooling 32 and the workpiece positioning assembly 33 to move towards or away from the assembly station 12. The tooling 32 has a limiting groove 3211 for accommodating and limiting the base assembly 8. The workpiece positioning assembly 33 is used to fix the base assembly 8 in the limiting groove 3211. In this way, the second loading mechanism 3, through the cooperation of the second translation drive 31, the tooling 32, and the workpiece positioning assembly 33, can achieve precise loading and positioning of the base assembly 8. The workpiece positioning assembly 33 can effectively prevent the base assembly 8 from moving during the transfer and assembly process, affecting the assembly accuracy, ensuring that the base assembly 8 is accurately positioned at the assembly station 12, and improving the assembly quality.

[0058] The aforementioned second translation drive 31 can use existing linear drive mechanisms such as telescopic cylinders or motor-screw-nut linear modules.

[0059] See Figure 3 As shown, in one embodiment of the tooling 32, the tooling 32 includes a limiting plate 321, a sliding block 322, and an elastic member (not shown in the figure). The limiting plate 321 has the aforementioned limiting groove 3211 and a sliding groove 3212 communicating with the limiting groove 3211. The sliding block 322 is slidably connected within the sliding groove 3212. One end of the elastic member is connected to the side wall of the sliding groove 3212 facing away from the limiting groove 3211, and the other end is connected to the sliding block 322. The elastic member has a spring force that drives the sliding block 322 to slide towards the limiting groove 3211. The sliding block 322 is used to abut against the base assembly 8 within the limiting groove 3211. The sliding block 322 has a clearance groove 3221 for partial insertion of the tension spring 72. Thus, when the base assembly 8 is inserted into the limiting groove 3211, the sliding pressure block 322 can slide into the limiting groove 3211 under the elastic force of the elastic element, pressing the base assembly 8 tightly into the limiting groove 3211, thereby achieving the initial positioning of the base assembly 8. In addition, the clearance groove 3221 on the sliding pressure block 322 provides clearance for the tension spring 72 to be attached to the base assembly 8, facilitating subsequent assembly operations.

[0060] The aforementioned elastic element can be a compression spring or other elastic component.

[0061] See Figure 3 As shown, in one embodiment of the workpiece positioning assembly 33, the workpiece positioning assembly 33 includes a pressure arm 331 and a pressure arm drive assembly 332. The bottom of the limiting groove 3211 has a through hole (not shown in the figure) for the pressure arm 331 to pass through. There is one or two pressure arms 331. The pressure arm drive assembly 332 is mounted on the output end of the second translation drive member 31 by means of screwing or welding, and is drively connected to one or two pressure arms 331. The pressure arm drive assembly 332 is used to drive the pressure arm 331 to insert into or pull out of the limiting groove 3211, and to drive the pressure arm 331 to move toward or away from the base assembly 8 within the limiting groove 3211, thereby fixing or releasing the base assembly 8. Thus, the pressure arm drive assembly 332 drives the pressure arm 331 to insert into the limiting groove 3211 and move towards the base assembly 8, thereby achieving further positioning of the base assembly 8 within the limiting groove 3211 and effectively preventing the base assembly 8 from moving during transfer and assembly. After assembly, the pressure arm drive assembly 332 drives the pressure arm 331 to move away from the base assembly 8 and pull it out of the limiting groove 3211, thereby releasing the further positioning of the base assembly 8 so that the assembled metal button assembly can be removed.

[0062] If there are two pressure arms 331, the pressure arm drive assembly 332 can be formed by combining a lifting cylinder 3321 and a clamping cylinder 3322. The lifting cylinder 3321 is mounted on the output end of the second translation drive 31 by means of screwing or welding. The output end of the clamping cylinder 3322 is connected to the two pressure arms 331 by means of screwing or welding. In this way, the lifting cylinder 3321 can drive the pressure arms 331 to insert or pull out of the limiting groove 3211, and the clamping cylinder 3322 can drive the two pressure arms 331 to move synchronously toward or away from the base assembly 8 in the limiting groove 3211 to clamp and fix or release the base assembly 8. If there is only one pressure arm 331, the pressure arm drive assembly 332 can be formed by combining a lifting cylinder 3321 and a telescopic cylinder. The installation method and function of the lifting cylinder 3321 are the same as above, while the output end of the telescopic cylinder is connected to a pressure arm 331 by means of screwing or welding. In this way, the telescopic cylinder can drive a pressure arm 331 to move towards or away from the base assembly 8 in the limiting groove 3211, so as to cooperate with the groove wall of the limiting groove 3211 to fix or loosen the base assembly 8.

[0063] See Figure 1 As shown, in one installation method of tooling 32, tooling 32 is movably mounted on the output end of the second translation drive 31. The second feeding mechanism 3 also includes a tooling positioning assembly 34. The tooling positioning assembly 34 is mounted on the output end of the second translation drive 31 and is used to fix tooling 32 on the output end of the second translation drive 31. In this way, the movable setting of tooling 32 allows for easy replacement of the corresponding tooling 32 according to the actual assembled metal button assembly. After replacement, tooling 32 can be fixed by tooling positioning assembly 34 to prevent the base assembly 8 from moving during the transfer and assembly process, thus affecting the assembly accuracy.

[0064] In addition to the above-mentioned movable installation method, tooling 32 can also be directly fixedly installed on the output end of the translation drive component. The latter installation method has lower versatility, but it can better ensure the consistency of the position of tooling 32 at the assembly station 12.

[0065] See Figure 3As shown, in one embodiment of the tooling positioning assembly 34, the tooling positioning assembly 34 includes a cam 341 and a cam drive member 342. The output end of the second translation drive member 31 is provided with a mounting plate 311 by means of screwing or welding. The mounting plate 311 has a receiving groove 3111 and a sliding channel 3112 communicating with the receiving groove 3111. The receiving groove 3111 is used to receive a tool 32. The cam 341 is slidably connected within the sliding channel 3112 and is used to abut against the tool 32 within the receiving groove 3111.
