[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] A workpiece holder for a fully automated microswitch welding production line, such as Figures 1-8As shown, the assembly includes a bracket 1, a floating block 2, a fixed base 3, a first guide rod 4, a first spring 5, a limiting component 6, and a pressing component 7. The first guide rod 4 is vertically mounted on the bracket 1, and the first spring 5 is mounted on the first guide rod 4; two first guide rods 4 are provided. The floating block 2 is slidably mounted on the first guide rod 4, and the first spring 5 is mounted on the first guide rod 4, with both ends of the first spring 5 acting on the floating block 2 and the bracket 1 respectively, thus causing the first spring 5 to act on the bottom of the floating block 2, providing an upward thrust to the floating block 2. A drive rod 8 is provided on the floating block 2, which pushes the floating block 2 downward. The fixed base 3 is mounted on the floating block 2, and the fixed base 3 has a first placement slot 31 and a second placement slot 32 for placing microswitch accessories. The limiting component 6 and the pressing component 7 are respectively located at the first placement slot 31 and the second placement slot 32. The limiting component 6 closes the upper opening of the first placement slot; the pressing component 7 presses the accessory into the second placement slot 32. The first placement slot 31 is shaped to match the switch body, and the switch body is inserted from the top of the first placement slot 31; the second placement slot 32 is used to place the pin, which is connected to the switch body through the pin. The clamping component 7 is clamped on the pin, thereby ensuring that the position between the switch body and the pin remains fixed. The switch body and the pin are fixed by welding equipment to complete the assembly of the micro switch.

[0025] In one embodiment, such as Figures 1-8 As shown, the limiting assembly 6 includes a limiting plate 61, a second spring 62, a third spring 63, and a driving block 64. A first guide groove 66 is horizontally arranged on the fixed base 3, and the limiting plate 61 is slidably disposed in the first guide groove 66. The second spring 62 connects the fixed base 3 and the limiting plate 61, and provides a pushing force for the limiting plate 61 to move towards the micro switch. A second guide groove 65 is vertically arranged on the fixed base 3, and the driving block 64 and the third spring 63 are disposed in the second guide groove 65. A through hole is provided at the bottom of the second guide groove 65, and the third spring 63 provides a downward pushing force for the driving block. The driving block 64 controls the limiting plate 61 to move away from the micro switch. The workpiece holder is used to switch between different workstations. A drive mechanism is set at the corresponding workstation. The drive mechanism passes through the through hole and acts on the drive block 64, pushing the drive block 64 upward. During this process, the third spring 63 stores force. As the drive block 64 moves upward, it pushes the limiting plate 61 to move horizontally. At the same time, the second spring 62 stores force. At this time, the top opening of the first placement slot opens, allowing the switch to be removed and placed. When the drive mechanism resets, the drive block 64 moves downward under the restoring force of the third spring 63, while the limiting plate 61 moves horizontally under the restoring force of the second spring 62, thus blocking the upper opening of the first placement slot.

[0026] In one embodiment, such as Figures 1-8As shown, the second guide groove 65 includes a first guide groove 651 and a second guide groove 652. The driving block 64 includes a continuously arranged flange 641, a first guide portion 642, a second guide portion 643, and a driving portion 644. A third spring 63 is sleeved on the first guide portion 642 and placed within the first guide groove 651. The second guide portion 643 is placed within the second guide groove 652. The third spring 63 acts on the flange 641. The cross-section of the second guide portion 643 is square. The second guide groove 652 and the second guide portion 643 are configured to fit in a square shape to prevent the driving block 64 from rotating and causing the driving portion 644 to change its square shape. Furthermore, the interaction between the flange 641 and the first guide groove 651, and between the second guide portion 643 and the second guide groove 652, ensures stable movement of the driving block 64.

[0027] In one embodiment, such as Figures 1-8 As shown, the drive unit 644 is an inclined plane. The inclined plane converts the upward thrust into a horizontal thrust, thereby pushing the limit plate 61 to move horizontally.

[0028] In one embodiment, such as Figures 1-8 As shown, two sets of limiting components 6 are provided, with the two sets of limiting components 6 respectively located on both sides of the first placement slot. By setting two limiting plates 61 to be pushed into the top of the first placement slot from both sides, the extension length of a single limiting plate 61 is shortened, so that the limiting plate 61 and the fixed base 3 always maintain a stable connection.

[0029] In one embodiment, such as Figures 1-8 As shown, the clamping assembly 7 includes a second guide rod 71, a fourth spring 72, an upper connecting block 73, a lower connecting block 74, and a pressing block 75. A guide hole is provided on the fixed base 3, and the second guide rod 71 is slidably connected to the guide hole. The upper connecting block 73 and the lower connecting block 74 are located at the upper and lower ends of the second guide rod 71, respectively. The fourth spring 72 is located on the second guide rod 71, and its two ends act on the lower connecting block 74 and the fixed base 3, respectively. The pressing block 75 is located on the upper connecting block 73 and is situated above the second placement groove 32. Similarly, the lower connecting block 74 is pushed upward by the driving mechanism, thereby causing the pressing block 75 to move upward. Simultaneously, the fourth spring 72 stores force. When the driving mechanism is released, the lower connecting block 74 is pushed downward by the fourth spring 72, causing the pressing block 75 to be pressed tightly into the second placement groove 32.

[0030] In one embodiment, such as Figures 1-8 As shown, two second guide rods 71 ​​are provided.

[0031] In one embodiment, such as Figures 1-8 As shown, the drive rod 8 is guided and connected to the bracket 1.

[0032] When using this utility model, such as Figures 1-8As shown, the workpiece holder is mounted on a moving mechanism, which moves between various stations to facilitate the loading, unloading, and welding of the switch body and pins. When it reaches the switch body loading station, the driving mechanism opens the limiting component 6, and the switch body is placed into the first placement slot 31, after which the limiting component 6 automatically closes. Upon reaching the pin loading station, another driving mechanism opens the clamping component 7, allowing the pin to be placed into the second placement slot 32 and clamped in place by the clamping component 7. Then, it moves to the welding station, where another set of driving components controls the driving rod 8 to move downwards, thus moving the floating block 2 downwards. In this embodiment, resistance welding is used, with welding heads on both the upper and lower surfaces of the welding point. The driving rod 8 pushes the floating plate 2 downwards, causing the lower surface of the switch body where it connects to the pin to contact the lower welding head. The welding equipment then drives the upper welding head to contact the upper surface of the switch body where it connects to the pin, completing the welding. Finally, it moves to the unloading station, where the limiting component 6 and the clamping component 7 are opened, allowing the welded switch to be removed.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of implementation of the present utility model. Any modifications or equivalent substitutions to the present utility model without departing from the spirit and scope thereof should be covered within the protection scope of the claims of the present utility model.
