[0002] A switch is an electronic component that can open a circuit, interrupt the current, or cause it to flow to other circuits. Common switches include micro switches, rocker switches, toggle switches, push switches, key switches, etc. Switches generally have multiple components, and during the production and processing process, multiple components need to be assembled into an integral product. Taking a key switch as an example, a common switch key generally includes a base, a shaft, a spring, a moving piece, a static piece, and other components. During the production process, each component needs to be assembled in a certain order. In order to achieve the sense of paragraph when pressing or trigger the key sound, some switch keys will also be equipped with a torsion spring. In traditional operations, the installation of torsion springs is generally carried out manually. With the help of positioning jigs and other tooling, the staff installs the torsion spring into the base of the key switch, and then transfers the assembly to the next process. This method is inefficient and labor-intensive, and it is also easy to be installed in place. Utility Model Content

[0023] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0024] Reference Figures 1 to 4The utility model provides a key switch torsion spring assembly device, comprising a chassis 1, a support platform 11 arranged on the chassis 1, a conveying mechanism 2 arranged on the support platform 11, a torsion spring feeding mechanism 3 arranged on the chassis 1, and a torsion spring installation mechanism 4 arranged on the support platform 11. The conveying mechanism 2 is used to convey the base of the key switch, the torsion spring feeding mechanism 3 provides the torsion spring, and the torsion spring installation mechanism 4 installs the torsion spring into the base.

[0025] The torsion spring installation mechanism 4 includes an installation support frame 41 arranged on the support platform 11, an X-axis moving module 42 arranged on the installation support frame 41, a Z-axis moving module 43 connected to the X-axis moving module 42, a clamping assembly 44 connected to the Z-axis moving module 43, and a compression torsion spring assembly 45 connected to the Z-axis moving module 43; the compression torsion spring assembly 45 includes a compression torsion spring cylinder 451 connected to the Z-axis moving module, and a lower pressure rod 452 connected to the output end of the compression torsion spring cylinder 451. In this embodiment, the conveying mechanism 2 conveys the base along the Y-axis direction, and the torsion spring installation mechanism 4 transfers the torsion spring from the X-axis direction to the top of the base and presses it downward into the base through the lower pressure rod 452.

[0026] The clamping assembly 44 includes a clamping claw cylinder 441 connected to the Z-axis moving module and a clamping member 442 connected to the output end of the clamping claw cylinder 441. The clamping member 442 clamps a torsion spring from the torsion spring feeding mechanism 3, and releases the torsion spring when moving to the base, so as to press the torsion spring into the base.

[0027] The torsion spring feeding mechanism 3 includes a feeding assembly 31 and a feeding assembly 32 for feeding the torsion spring to the torsion spring installation mechanism 4. The feeding assembly 31 includes a feeding seat 311, a straight vibration material channel 312 arranged on the feeding seat 311, a material stopper 313 arranged at the end of the straight vibration material channel 312, and a material stopper cylinder 314 for driving the material stopper 313 to move. The moving direction of the material stopper 313 is perpendicular to the conveying direction of the straight vibration material channel 312, that is, it moves along the X-axis direction. The straight vibration material channel 312 specifically connects a material channel for conveying torsion springs to the straight vibrator. The material stopper 313 can stop the torsion spring when the torsion spring reaches the end of the straight vibration material channel 312, so as to facilitate the feeding assembly 32 to deliver the torsion spring to the material taking position of the torsion spring installation mechanism 4.

[0028] The feeding assembly 32 includes a Y-axis moving module 321, a fixed clamping seat 322 connected to the Y-axis moving module 321, a mobile clamping portion 323 connected to the fixed clamping seat 322, and a clamping cylinder 324 for driving the mobile clamping portion 323 to move. Specifically, the fixed clamping seat 322 has a fixed clamping portion corresponding to the mobile clamping portion 323, and the torsion spring can be clamped out of the straight vibration material channel 312 under the cooperation of the mobile clamping portion 323 and the fixed clamping portion.

[0029] The X-axis moving module 42 and the Y-axis moving module 321 both include a guide rail 421, a slider 422, and a moving cylinder 423 for driving the slider 422 to move. Of course, an electric screw module can also be used in the specific implementation.

[0030] The key switch torsion spring assembly device includes an oiling mechanism 5 disposed on the support platform 11, the oiling mechanism 5 includes an oiling bracket 51, an oiling cylinder 52 disposed on the oiling bracket 51, and an oiler 53 connected to the output end of the oiling cylinder 52. The oiling mechanism 5 can pre-apply oil to the base to ensure the smoothness of the subsequent key switch.

[0031] The conveying mechanism 2 includes a conveying channel 21 arranged on the support platform 11, a pusher assembly 22 arranged on the support platform 11, and a vibration plate 23 for conveying the case switch base to the conveying channel 21. The pusher assembly 22 includes a pusher plate 221 movably connected to the support platform 11, a plurality of pushers 222 arranged on the pusher plate 221, and a pusher cylinder 223 for driving the pusher plate 221 to move. The pusher 222 is located above the conveying channel 21. The material-pickup member and the pusher plate 221 are rotatably connected, and a torsion spring for resetting is connected between the two. The material-pickup member is locked in one direction, that is, locked near the starting end of the conveying channel 21. When the pusher plate 221 moves toward the end of the conveying channel 21, the material-pickup member can push the base to move a certain distance. When the moving plate returns, the material-pickup member rotates after contacting the base, so that the base will not be pushed to move. After the material-pickup member passes the base, it is reset under the action of the torsion spring. An elastic limiting component 26 for pressing the product is arranged on one side of the conveying channel 21. The elastic limiting component 26 is specifically a limiting member arranged on the side wall of the conveying channel 21, and the limiting member presses the base under the action of a spring.

A defective product cylinder 25 for driving the dividing block 24 to move is provided on the support platform 11, and the dividing block 24 can close or open the defective product discharge channel 12 when driven by the defective product cylinder 25.

[0033] The key switch torsion spring assembly device includes a detection mechanism 6, which includes a detection bracket 61 arranged on the support platform 11, a detection cylinder 62 arranged on the detection bracket 61, and a detection probe 63 connected to the output end of the detection cylinder 62. When a defective product is detected, the material dividing block 24 moves to open the defective product discharge channel 12, so that the defective product can be discharged from the defective product discharge channel 12. In addition, a discharge channel can be set at the end of the conveying channel 21 for sending out qualified products.

[0034] In this embodiment, the oiling mechanism 5, the torsion spring installation mechanism 4, and the detection mechanism 6 are sequentially arranged on one side of the conveying channel 21 along the conveying direction of the base. During specific operation, the vibration plate 23 sends the base into the conveying channel 21, and with the cooperation of the push plate 221 and the material-dispensing member, the base can move a set distance at a time, so as to sequentially pass through the corresponding positions of the oiling mechanism 5, the torsion spring installation mechanism 4, and the detection mechanism 6, and respectively perform oiling, torsion spring installation, and detection, and finally complete the torsion spring installation.

[0035] The utility model is provided with a torsion spring installation mechanism 4. With the cooperation of the conveying mechanism 2, the torsion spring provided by the torsion spring feeding mechanism 3 can be installed in the base of the push-button switch. The loading and conveying of product components are automated without manual operation, which reduces labor intensity and improves work efficiency. At the same time, the automated actions are highly consistent, ensuring that the torsion spring is installed in place and the yield rate is guaranteed to the greatest extent.
