The second turntable 210 then rotates with the second fixture 211 to the NC terminal feeding mechanism 230. The NC terminal feeding mechanism 230 automatically feeds the NC terminal g. Similarly, the second rotating drive disk 300 drives the corresponding second pick-and-place mechanism 310 to clamp the NC terminal g at the NC terminal feeding mechanism 230 and place it in the semi-finished product of the second fixture 211. The second turntable 210 continues to rotate with the second fixture 211 and rotates to the button feeding mechanism 240. The button feeding mechanism 240 automatically feeds the button h, and the corresponding second pick-and-place mechanism 310 clamps the loaded button h and places it in the semi-finished product of the second fixture 211.

[0037] In addition, the rotation of the first turntable 110 and the second turntable 210 in this embodiment adopts the cam divider in the prior art, and the rotation structure of the first rotating disk 170 and the second rotating disk 300 is also the prior art. At the same time, the structure of the dust removal mechanism 250 (air pipe blowing) and the pressing mechanism 290 (pressing plate pressing down) are also the prior art, so they will not be elaborated here.

The rotating clamping unit 164 includes a support The support frame 164a, the up-down movable plate 164b, the translation seat 164c, the swing arm 164d, the rotating shaft 164e and the clamping claw 164f, the up-down movable plate 164b is movably arranged on the support frame 164a, and an L-shaped movable groove 164g is opened on the up-down movable plate 164b, the translation seat 164c is arranged on the up-down movable plate 164b, the middle part of the rotating shaft 164e is rotatably connected with the translation seat 164c, and one end of the rotating shaft 164e is connected to one end of the swing arm 164d, and the other end is connected to the clamping claw 164f, and the other end of the swing arm 164d is rotatably arranged with a third roller 164h, and the third roller 164h is arranged in the L-shaped movable groove 164g.

[0047] Specifically, when the support rod d is loaded onto the first fixture 111, the first turntable 110 will rotate with the first fixture 111 to the plastic shell assembly mechanism 160, and one end of the plastic shell loading channel 161 in the plastic shell assembly mechanism 160 is connected to the corresponding vibration plate, and the vibration plate will vibrate the plastic shell e into the plastic shell loading channel 161 in sequence, and the plastic shell e is transported along the plastic shell loading channel 161 and transported from the tail end of the plastic shell loading channel 161 to the assembly seat 162. At this time, the rotating The rotating clamping unit 164 clamps the movable piece a, the spring piece b, the COM terminal c and the support rod d in the first fixture 111 as a whole, and places them in the plastic shell e of the assembly seat 162, thereby realizing the assembly of the movable piece a, the spring piece b, the COM terminal c, the support rod d and the plastic shell e to form a semi-finished product. After the semi-finished product is assembled, the push rod 163 will push the semi-finished product on the assembly seat 162 to the conveyor belt 30, and the conveyor belt 30 will transfer the semi-finished product to the rear-stage assembly 20.

[0048] Furthermore, in order to realize the clamping and assembly of the moving piece a, the spring piece b, the COM terminal c and the support rod d in the first fixture 111, when the first fixture 111 is rotated to the plastic shell assembly mechanism 160, the corresponding cylinder will drive the translation seat 164c to move toward the first fixture 111. When the translation seat 164c moves laterally, the middle part of the rotating shaft 164e will rotate with the translation seat 164c as the center. During the rotation, one end of the rotating shaft 164e will drive the clamping claw 164f to rotate, and the other end will rotate while driving the third roller 164h to move along the L-shaped moving groove 164g because it is rotationally connected to the third roller 164h. When the translation seat 164c moves to the set position, the clamping claw 164f will rotate 90°, and then the moving piece a and the spring piece in the first fixture 111 are clamped by the clamping claw 164f. b, COM terminal c and support rod d are clamped as a whole. After clamping, the corresponding cylinder drives the translation seat 164c to reset backward. When resetting, the translation seat 164c will reset with the clamping claw 164f and the third roller 164h. At this time, the up and down moving plate 164b moves downward, so that the clamping claw 164f moves downward to the set position, and the clamped movable plate a, spring piece b, COM terminal c and support rod d are placed in the plastic shell e of the assembly seat 162, so as to realize the automatic assembly of the semi-finished products of the movable plate a, spring piece b, COM terminal c, support rod d and plastic shell e, and make its assembly process reasonable and improve the assembly efficiency. At the same time, the structure of the rotating clamping unit 164 can ensure the accuracy of clamping the movable plate a, spring piece b, COM terminal c and support rod d, so that the position is accurate when placed in the plastic shell e, and the qualified rate of assembly is ensured.

The second pick-and-place mechanism 310 includes a second slide rail 311, a second mounting seat 312 and a pick-and-place member 313. A second roller 314 is provided at one end of the second slide rail 311, and the second roller 314 is arranged in the second driving groove 301. The second mounting seat 312 is fixed to the other end of the second slide rail 311, and the pick-and-place member 313 is arranged on the second mounting seat 312.

[0050] After the conveyor belt 30 transports the semi-finished products of the movable plate e, the spring piece b, the COM terminal c, the support rod d and the plastic shell e to the tail end, the second pick-and-place mechanism 310 corresponding to the tail end of the conveyor belt 30 will clamp the semi-finished product and place it in the second fixture 211 of the second turntable 210. Specifically, the second rotating drive disk 300 rotates to move the second roller 314 along the second driving groove 301. When the second roller 314 moves, it will move with the second slide rail 311. During the movement, the second slide rail 311 will also move with the second mounting seat 312, so that the pick-and-place member 313 moves, clamps the semi-finished product at the tail end of the conveyor belt 30, and clamps it into the second fixture 211. The second turntable 210 then rotates with the second fixture 211 to realize the transportation of the semi-finished product.

[0051] The pick-and-place component 313 in this embodiment may adopt a clamping claw or an adsorption head. For example, in this embodiment, in the second pick-and-place mechanism 310 corresponding to the tail end of the conveyor belt 30, the NO terminal feeding mechanism 220, the NC terminal feeding mechanism 230, the button feeding mechanism 240 and the handle feeding mechanism 260, the pick-and-place component 313 may adopt a clamping claw, while the pick-and-place component 313 of the second pick-and-place mechanism 310 corresponding to the rubber cover feeding mechanism 280 adopts an adsorption head. The specific selection and setting can be made according to actual needs.

[0052] See also Fig.13 In this embodiment, in order to realize automatic loading of the NO terminal f, the NO terminal loading mechanism 220 includes a second loading channel 221 and a second offset rotating seat 222. The second offset rotating seat 222 is arranged at the tail end of the second loading channel 221, and a second offset groove 223 is arranged on the second offset rotating seat 222, and the second offset rotating seat 222 can rotate 90°. Specifically, when the corresponding second pick-and-place mechanism 310 clamps the semi-finished product at the tail end of the conveyor belt 30 and places it on the second fixture 211, the second turntable 210 will rotate with the second fixture 211 to the NO terminal feeding mechanism 220, and the second feeding channel 221 of the NO terminal feeding mechanism 220 is connected to the corresponding vibration disk, and the vibration disk will vibrate the NO terminal f into the second feeding channel 221 in sequence, and the NO terminal f is transported along the second feeding channel 221 and transported to the second offset groove 223 of the second offset rotating seat 222. At this time, the second offset rotating seat 222 will rotate 90° under the drive of the corresponding motor (not shown in the figure), so that the second offset groove 223 of the second offset rotating seat 222 rotates to face upward, and the pick-and-place member 313 of the second pick-and-place mechanism 310 will clamp the NO terminal f in the second offset rotating groove 223 and place it in the semi-finished product of the second fixture 211, thereby realizing automatic feeding of the NO terminal f.

[0053] Finally, since the structures of the NC terminal feeding mechanism 230, the button feeding mechanism 240 and the handle feeding mechanism 260 are the same as those of the NO terminal feeding mechanism 220, the NC terminal g, the button h and the handle i can also be automatically fed. Therefore, they are not described in detail here. The rubber cover feeding mechanism 280 includes a rubber cover feeding channel and a rubber cover transfer table. One end of the rubber cover feeding channel is connected to the corresponding vibration plate. The vibration plate vibrates the rubber cover j to the rubber cover feeding channel in sequence. The rubber cover j moves along the rubber cover feeding channel. The rubber cover j is transported along the rubber cover feeding channel and transported to the rubber cover transfer table, and then the corresponding second pick-and-place mechanism 310 absorbs the rubber cover j to the second fixture 211 and covers it with the semi-finished rubber shell e. The second turntable 210 then brings the second fixture 211 to the pressing mechanism 290, and the pressing mechanism 290 presses the rubber cover j and the rubber shell e tightly, thereby realizing the automated assembly of the micro switch, thereby improving the assembly efficiency and assembly quality of the micro switch and ensuring the assembly qualification rate of the micro switch.
