[0027] like Figure 1-6 As shown, this embodiment of the invention provides a scissor-switch assembly device for computer keyboard manufacturing, including a body assembly 1 and an assembly mechanism 2. The body assembly 1 includes a frame 101, a housing 102, a conveying unit 103, a supporting top plate 104, and a placement plate 105. The assembly mechanism 2 includes a first motor 201, a second motor 202, a first threaded rod 203, a support frame 204, a connecting plate 205, a material picking rod 206, a cutting blade 207, and a hydraulic cylinder 208. The housing 102 is fixedly connected to one side of the upper surface of the frame 101, and the inner bottom wall of the housing 102 is fitted with... The machine is equipped with a second motor 202. A fixed frame 44 is slidably connected to the inner side wall of the frame 101. A first motor 201 is installed on the top of the fixed frame 44. A first threaded rod 203 is fixedly connected to the output shaft of the first motor 201. The bottom of the first threaded rod 203 is connected to the inner side wall of the fixed frame 44 through a bearing shaft. A support frame 204 is provided below the first threaded rod 203. A connecting plate 205 is fixedly connected to the lower surface of the support frame 204. Picking rods 206 are evenly installed on the inner side wall of the connecting plate 205. A cutting blade 207 is fixedly connected to the bottom of the picking rod 206.

[0028] In one embodiment, the output shaft of the second motor 202 is fixedly connected to a second threaded rod 41. One end of the second threaded rod 41 is rotatably connected to one side of a support block 42 via a bearing. The bottom of the support block 42 is fixedly connected to the inner bottom wall of the housing 102. The support block 42 provides support for one end of the second threaded rod 41, and the output shaft of the second motor 202 drives the second threaded rod 41 to move.

[0029] In one embodiment, a first threaded block 43 is threadedly connected to one side of the outer wall of the second threaded rod 41, and the outer wall of the first threaded block 43 is fixedly connected to one side of the inner wall of the fixing frame 44; the rotating second threaded rod 41 drives the fixing frame 44 to move through the first threaded block 43.

[0030] In one embodiment, two hydraulic cylinders 208 are symmetrically fixedly connected to the outer wall of the fixing frame 44, and the piston rods of the two hydraulic cylinders 208 are fixedly connected to the upper surface of the pressing plate 48. The pressing plate 48 is driven to move by the piston rods of the hydraulic cylinders 208, and the moving pressing plate 48 performs the pressing and fixing work on the scissor-foot coarse material on the placement plate 105.

[0031] In one embodiment, a support top plate 104 is fixedly connected to one side of the inner wall of the frame 101, and a shelf 105 is fixedly connected to the upper surface of the support top plate 104; the support top plate 104 provides support for the bottom of the shelf 105.

[0032] In one embodiment, a sub-assembly groove 52 is uniformly provided on one side of the upper surface of the shelf 105, and a female assembly groove 53 is uniformly provided on the other side of the upper surface of the shelf 105; the sub-assembly groove 52 and the female assembly groove 53 are used to limit the rough material of the scissor foot.

[0033] In one embodiment, a base plate 51 is installed on one side of the upper surface of the supporting top plate 104, an assembly plate 47 is installed on the upper surface of the base plate 51, and a conveying unit 103 is installed on one side of the inner wall of the frame 101; the base plate 51 provides support for the bottom of the assembly plate 47, and the conveying unit 103 is used to convey and recycle waste materials.

[0034] In one embodiment, a second threaded block 54 is threadedly connected to the middle of the outer side wall of the first threaded rod 203. The outer side wall of the second threaded block 54 is fixedly connected to the inner side wall of the support frame 204. Four guide blocks 49 are symmetrically fixedly connected to the outer side wall of the support frame 204. Four guide strips 50 are symmetrically fixedly connected to the inner side wall of the fixed frame 44. The outer side wall of the guide strips 50 is slidably connected to the inner side wall of the guide blocks 49. The guide blocks 49 slide on the outer side wall of the guide strips 50 to guide the support frame 204. The movement of the second threaded block 54 drives the support frame 204 to move.

[0035] In one embodiment, two guide rails 45 are symmetrically fixedly connected to the upper surface of the supporting top plate 104, and two sliders 46 are slidably connected to the outer side walls of the two guide rails 45. The tops of the two sliders 46 are fixedly connected to the lower surface of the fixed frame 44. By sliding the sliders 46 on the guide rails 45, the fixed frame 44 and the first motor 201 are guided, which increases the stability of the fixed frame 44 during movement.

[0036] In operation, this invention works as follows: a robotic arm places the keyboard scissor pin blanks onto the shelf 105. The assembly sub-slot 52 and assembly female slot 53 then limit the blanks. The output shaft of the second motor 202 drives the second threaded rod 41 to rotate. The rotating threaded rod 41, through the first threaded block 43, moves the fixing frame 44. The moving fixing frame 44 then moves the first motor 201 and the slider 46. The slider 46 slides on the guide rail 45, guiding the fixing frame 44 and the first motor 201, increasing the stability of the fixing frame 44 during movement. This moves the fixing frame 44 above the shelf 105. Finally, the piston rod of the hydraulic cylinder 208... The moving clamping plate 48 compresses and fixes the rough material with scissor-shaped feet on the placement plate 105. Then, the output shaft of the first motor 201 drives the first threaded rod 203 to rotate. The rotating first threaded rod 203 drives the support frame 204 to move through the second threaded block 54. The moving support frame 204 drives the connecting plate 205 and the guide block 49 to move. The moving guide block 49 slides on the outer wall of the guide strip 50 to guide the support frame 204. The moving connecting plate 205 drives the picking rod 206 to move. The moving picking rod 206 drives the cutting blade 207 to cut the rough material with scissor-shaped feet. Then, the cutting material is cut into the assembly sub-slot 52 by the picking rod 206. The hydraulic cylinder 208 grips the scissor-leg parts, and then the piston rod of the hydraulic cylinder 208 drives the clamping plate 48 to move upward, so that the cut waste material falls onto the conveying unit 103 through the placement plate 105 and the support top plate 104. The conveying unit 103 then transports and recycles the waste material. Then, the output shaft of the first motor 201 rotates in the reverse direction, causing the picking rod 206 to move the scissor-leg parts in the assembly sub-slot 52 upward. Then, the output shaft of the second motor 202 rotates in the reverse direction, causing the picking rod 206 to move the scissor-leg parts to the top of the assembly mother slot 53. Then, the first motor 201 drives the picking rod 206 to insert into the assembly mother slot 53, thereby gripping the parts in the assembly sub-slot 52. The components are initially assembled with the parts in the assembly slot 53. The picking rod 206 picks up the initially assembled parts and then the first motor 201 drives the picking rod 206 to pull the parts out of the assembly slot 53. Then, the output shaft of the second motor 202 drives the fixing frame 44 and the first motor 201 to move laterally, so that the picking rod 206 is above the assembly plate 47. Then, the first motor 201 drives the picking rod 206 to insert into the inner wall of the assembly plate 47, thereby reassembling the initially assembled parts. This allows for the automatic assembly of computer keyboards, reducing the number of workstations during assembly, saving manpower, and increasing the production efficiency of computer keyboards.

Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
