[0013] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] Reference Figures 1 to 4 As shown, this utility model provides an automatic feeding device for keyboard scissor switches. In one embodiment, it includes a feeding platform 1, a feeding track 2, and a vibrating plate 3 installed on the top of the feeding platform 1. The feeding track 2 has an L-shaped structure, and the vertical end of the L-shaped feeding track 2 is connected to the vibrating plate 3. The horizontal end of the L-shaped feeding track 2 is arranged at one end of the feeding platform 1. The connection between the horizontal end and the vertical end of the L-shaped feeding track 2 has an arc-shaped structure, and a feeding support column 4 is also connected to the bottom of the connection between the horizontal end and the vertical end of the L-shaped feeding track 2. The top of the feeding support column 4 is also equipped with a pressing and translating mechanism 5, and the pressing and translating mechanism 5 is also driven and connected to a pressing plate 51; the top of the feeding track 2 is also provided with an L-shaped feeding guide groove, and the connection between the L-shaped horizontal end and the L-shaped vertical end of the feeding guide groove is arc-shaped; the top of the L-shaped horizontal end of the feeding track 2 is provided with a feeding slot hole, and the feeding slot hole is connected to the end of the L-shaped horizontal end of the feeding guide groove; a fiber optic sensor 22 is also arranged on one side of the feeding slot hole, and the pressing plate 51 is arranged above the feeding slot hole.

[0015] Continue to refer to Figures 1 to 4 As shown, in this embodiment, the device also includes a feeding frame, with the feeding platform 1 arranged inside the feeding frame. To improve feeding efficiency, the feeding platform 1, vibratory plate 3, and feeding track 2 are all provided in two sets. The L-shaped horizontal ends of the two feeding tracks 2 are connected together to form a U-shaped track. In order to further improve feeding efficiency, two feeding guide grooves are provided on each feeding track 2. Correspondingly, the pressing and translating mechanism 5 on each feeding track 2 also drives and connects two pressing plates 51. In this way, the feeding of four scissor legs can be achieved at one time, resulting in high working efficiency. At the same time, the pressing and translating mechanism 5 is provided so that the pressing plates 51 can be driven to move above the feeding groove hole during feeding, preventing the scissor legs from being ejected due to excessive inertia after being transmitted into the feeding groove hole. Furthermore, an optical fiber sensor 22 is arranged on one side of the feeding groove hole to sense whether the material is in place, so that the external assembly robot can be controlled by the back end to pick up the scissor legs.

[0016] Preferably, in this embodiment, a first receiving groove is provided at the bottom of the feeding track 2 corresponding to the feeding slot hole, and a feeding spring block 23 is movably arranged in the first receiving groove; a feeding extension block 24 extends upward from each of the top two ends of the feeding spring block 23; a first insertion hole is provided at each of the two ends of the feeding slot hole, and the upper part of each feeding extension block 24 is movably arranged through a first insertion hole; a spring cover 25 is connected to the bottom opening of the first receiving groove, and a first spring 26 is provided between the bottom of the feeding spring block 23 and the top of the spring cover 25.

[0017] In this embodiment, the upper part of each feeding extension block 24 is arranged to move through a first insertion hole, that is, the two feeding extension blocks 24 are respectively arranged at one end of the feeding slot. When the vibrating plate 3 transmits the scissor foot to the feeding slot through the feeding guide groove, the two feeding extension blocks 24 can limit their ends. At the same time, a first spring 26 is connected between the bottom of the feeding spring block 23 and the top of the spring cover 25. When the assembly robot grips the scissor foot, it will first press down the feeding extension block 24, pressing it down into the first receiving slot (at this time, the first spring 26 is in a compressed state), thereby releasing the space for the robot to grip the scissor foot. After the robot grips the scissor foot and removes it, the feeding extension block 24 will rise and reset under the drive of the restoring force of the first spring 26, and so on.

[0018] Meanwhile, a spring limiting hole is provided at the bottom of the feeding spring block 23, and the upper part of the first spring 26 is inserted into the spring limiting hole. The upper part of the first spring 26 is inserted into the spring limiting hole to prevent the spring from shifting during compression or recovery, thus ensuring the stability of the structure. In addition, each end of one side of the feeding extension block 24 is provided with an outwardly inclined first guide surface 21. The function of the first guide surface 21 is to guide the scissor foot to slide smoothly into the feeding slot when it enters the feeding slot, thereby improving the smoothness and efficiency of feeding.

[0019] Preferably, the top of the feeding track 2 is provided with a first mounting groove on one side of the feeding slot hole, and the first mounting groove communicates with the feeding slot hole; the fiber optic sensor 22 is installed in the first mounting groove, and part of the fiber optic sensor 22 is arranged in the feeding slot hole; a clamping block is also installed in the first mounting groove to press and limit the fiber optic sensor 22. The clamping block can firmly fix the fiber optic sensor 22 in the first mounting groove to prevent the fiber optic sensor 22 from loosening or shifting during operation.

[0020] In one embodiment, the pressing and translating mechanism 5 includes a pressing mounting block 52 connected to the top of the feeding support column 4, a pressing and translating cylinder 53 mounted on the pressing mounting block 52, a pressing pull rod 54 arranged above the L-shaped horizontal end of the feeding track 2 along its length direction, and a pressing sliding plate 55 slidably arranged on one side of the top of the L-shaped horizontal end of the feeding track 2 and connected to the pressing pull rod 54; the pressing plate 51 is connected to one end of the pressing sliding plate 55. In this embodiment, each end of the pressing sliding plate 55 is connected to a pressing plate 51, and each pressing plate 51 is arranged close to a feeding slot hole. The pressing and translating cylinder 53 can drive the pressing plate 51 to move above the feeding slot hole via the pressing pull rod 54 and the pressing sliding plate 55, thereby preventing the scissor foot from popping out due to excessive inertia after being transmitted into the feeding slot hole. At the same time, after the scissor foot is successfully transmitted into the feeding slot hole, it is moved away, which facilitates the assembly robot to grasp the scissor foot.

[0021] To improve the stability of the movement of the pressure plate 51, preferably, a first notch is provided on one side of the top of the L-shaped horizontal end of the feeding track 2 along its length, and a first linear guide assembly 56 is arranged in the first notch; the pressure sliding plate 55 is slidably connected to the first linear guide assembly 56.

[0022] To improve the smoothness of the scissor blades' movement within the feeding guide groove, preferably, several feeding air blowing assemblies 6 are also installed on the top of the feeding track 2 on one side of the feeding guide groove; each feeding air blowing assembly 6 includes an air blowing fixing block 61 and a feeding air blowing pipe 62 installed on the air blowing fixing block 61. The feeding air blowing pipe 62 can be connected to an external air source to blow air into the feeding guide groove, allowing the scissor blades to move more smoothly within the feeding guide groove.

[0023] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
