[0014] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] Reference Figures 1 to 10As shown, this utility model provides an automatic assembly device for keyboard scissor-switch feet. In one embodiment, it includes a scissor-switch foot feeding mechanism 1 and a transfer assembly mechanism 2 arranged on one side of the scissor-switch foot feeding mechanism 1. The transfer assembly mechanism 2 includes a transfer worktable 21, an assembly X-axis translation mechanism 22 mounted on the top of the transfer worktable 21, an assembly translation plate connected to the assembly X-axis translation mechanism 22, an assembly Y-axis translation mechanism 23 mounted on the top of the assembly translation plate, and an assembly translation frame 24 connected to the assembly Y-axis translation mechanism 23. An assembly Z-axis lifting mechanism 25 is also mounted on one side of the assembly translation frame 24. The assembly Z-axis lifting mechanism 25 is also driven and connected to an assembly lifting frame 26; the assembly lifting frame 26 is located above the scissor-foot feeding mechanism 1, and the bottom of the assembly lifting frame 26 is also connected to an assembly fixing plate 27; a number of assembly modules 28 are installed at intervals along the length of the assembly fixing plate 27; the assembly module 28 includes an assembly fixing seat 282 connected to the bottom of the assembly fixing plate 27, an assembly pressing cylinder 281 installed on the top of the assembly fixing plate 27, and an assembly chuck assembly connected to the assembly pressing cylinder 281; the lower part of the assembly chuck assembly is arranged to move through the assembly fixing seat 282.

[0016] In this embodiment, the assembly X-axis translation mechanism 22, the assembly Y-axis translation mechanism 23, and the assembly Z-axis lifting mechanism 25 all adopt the transmission method of motor lead screw. With the cooperation of the three, the assembly module 28 can be driven to perform translation and lifting movements, so that the assembly module 28 can pick up the scissor feet from the scissor foot feeding mechanism 1 and assemble them in the corresponding positions in the keyboard frame. At the same time, in order to improve work efficiency, there are four assembly modules 28 in this embodiment, so that the assembly of four scissor feet can be completed at one time.

[0017] Preferably, the assembly chuck assembly includes an assembly chuck seat 283 and an assembly pressing column 284 connected to an assembly pressing cylinder 281; one end of the lower part of the assembly pressing column 284 has an oblong hole extending to the other end in a vertical direction; the assembly chuck seat 283 is movably sleeved on the lower part of the assembly pressing column 284, and a first connecting pin 2831 is connected between the two ends of the assembly chuck seat 283; the two ends of the first connecting pin 2831 are respectively movably arranged through an oblong hole; each end of the assembly chuck seat 283 has an assembly clamping plate 2832 on its inner wall, and the assembly clamping plate 2832... 32 are fitted onto the first connecting pin 2831; the lower part of the assembly clamp 2832 extends downward from the bottom of the assembly clamp seat 283, and a first retaining strip 2833 extends outward from the lower part of each of the two assembly clamps 2832 on opposite sides; a first spring hole is also provided in the assembly pressing column 284 along the vertical direction, and a first guide pin 2834 is also arranged in the first spring hole; the bottom of the first guide pin 2834 is arranged in the middle of the top of the first connecting pin 2831, and a first buffer spring 2835 is also provided between the top of the first guide pin 2834 and the bottom of the first spring hole.

[0018] After the assembly module 28 moves to the material-grabbing position on the scissor-foot feeding mechanism 1, the assembly module 28 descends, thereby clamping the scissor feet by the two assembly clamping plates 2832 (a certain gap is left between the assembly clamping plate 2832 and the first connecting pin 2831, allowing the assembly clamping plate 2832 to move slightly to clamp the scissor feet). The scissor feet will be locked onto the first locking strip 2833. Then the assembly module 28 rises and moves to the assembly position. Subsequently, the assembly module 28 descends to the corresponding position on the keyboard frame and continues to press down under the drive of the assembly pressing cylinder 281. After the assembly clamping plate 2832 contacts the keyboard frame, it is subjected to the reaction force of the keyboard frame. Under the influence of force, the first connecting pin 2831 will drive the assembly chuck seat 283 to rise. At the same time as rising, the assembly pressing column 284 will press down the scissor legs, thereby pressing the scissor legs from the first clip 2833 into the corresponding hole in the keyboard frame to complete the assembly. Meanwhile, during the rising process of the assembly clamp 2832, the first connecting pin 2831 will rise along the oval hole, which will push the first guide pin 2834 to rise to squeeze the first buffer spring 2835 and put it in a compressed state. After the assembly is completed, when the assembly module 28 rises, the assembly clamp 2832 can be driven to fall and reset under the driving force of the first buffer spring 2835.

[0019] Meanwhile, to ensure that the first locking strip 2833 can smoothly engage and release the scissor legs, preferably, the bottom of the first locking strip 2833 has an upwardly inclined first surface, and the top of the first locking strip 2833 has a downwardly inclined second surface; and the bottom of the assembly clamping plate 2832, located below the first locking strip 2833, also has an upwardly inclined third surface. The third inclined surface allows the scissor legs to smoothly enter between the two assembly clamping plates 2832 when gripping them.

[0020] Furthermore, a first sliding groove is formed horizontally on one side of the lower part of the assembly pressing column 284, and a second sliding groove is formed vertically on one side of the lower part of the assembly pressing column 284, communicating with the first sliding groove and extending to the bottom of the assembly pressing column 284; the assembly clamp assembly also includes an assembly pressing block 285; the assembly pressing block 285 has a T-shaped structure, with the horizontal end of the T-shaped assembly pressing block 285 arranged in the first sliding groove, and the vertical end of the T-shaped assembly pressing block 285 passing through the second sliding groove; the assembly The lower part of the T-shaped vertical end of the pressure block 285 is also provided with a first inclined block 2851 that is inclined downward toward the assembly pressure column 284; the assembly pressure column 284 is also provided with a second spring hole that extends to the first slide groove in the vertical direction, and a second guide pin 2852 is also arranged in the second spring hole; the bottom of the second guide pin 2852 is arranged at the top of the T-shaped horizontal end of the assembly pressure block 285, and a second buffer spring 2853 is also provided between the top of the second guide pin 2852 and the bottom of the second spring hole.

[0021] When the assembly pressing column 284 presses down on the assembly scissor legs, the assembly pressing block 285 will simultaneously press down on the rotatable parts in the scissor legs to ensure the smooth assembly of the scissor legs. At the same time, under the influence of the reaction force, the assembly pressing block 285 will rise and squeeze the second buffer spring 2853 during the pressing process, so that it is in a compressed state. After the assembly is completed, during the rising process of the assembly pressing column 284, the assembly pressing block 285 can be driven to fall and reset under the restoring force of the second buffer spring 2853.

[0022] In one embodiment, the top of the assembly fixing base 282 is provided with a first guide hole extending to its bottom, and the lower part of the assembly pressing column 284 is movably arranged through the first guide hole. An assembly connecting block 286 is connected to the top of the assembly pressing column 284, and the assembly connecting block 286 is connected to the output shaft of the assembly pressing cylinder 281. The assembly pressing column 284 is arranged through the first guide hole, which guides the assembly pressing column 284 during lifting and lowering, ensuring its stability. Simultaneously, the assembly connecting block 286, which is larger than the first guide hole, limits the downward stroke of the assembly pressing column 284.

[0023] In one embodiment, the scissor-foot feeding mechanism 1 includes a feeding platform 11, a feeding track 12, and a vibratory feeder 13 mounted on the top of the feeding platform 11. The feeding track 12 has an L-shaped structure, with the vertical end of the L-shaped feeding track 12 connected to the vibratory feeder 13, and the horizontal end of the L-shaped feeding track 12 arranged at one end of the feeding platform 11. The connection between the horizontal and vertical ends of the L-shaped feeding track 12 has an arc-shaped structure, and a feeding support column 14 is also connected to the bottom of the connection between the horizontal and vertical ends of the L-shaped feeding track 12. A pressure plate is also installed on the top of the feeding support column 14. The translation mechanism 15 is also driven and connected to the pressure plate 151; the top of the feeding track 12 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 12 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 122 is also arranged on one side of the feeding slot hole, and the pressure plate 151 is arranged above the feeding slot hole; the assembly module 28 is arranged above the L-shaped horizontal end of the feeding track 12.

[0024] In this embodiment, the device also includes a feeding frame, with a feeding platform 11 arranged inside the feeding frame. To improve feeding efficiency, the feeding platform 11, vibratory feeder 13, and feeding track 12 are all provided in two sets. The L-shaped horizontal ends of the two feeding tracks 12 are connected together to form a U-shaped track. The transfer assembly mechanism 2 is arranged inside the U-shaped track. In order to further improve feeding efficiency, two feeding guide grooves are provided on each feeding track 12. Correspondingly, the pressing and translating mechanism 15 on each feeding track 12 also drives and connects two pressing plates 151. 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 15 can drive the pressing plates 151 to move above the feeding slot during feeding to prevent the scissor legs from popping out due to excessive inertia after being transmitted into the feeding slot. A fiber optic sensor 122 is also arranged on one side of the feeding slot to sense whether the material is in place, so that the back-end control assembly module 28 can clamp the scissor legs.

[0025] Preferably, in this embodiment, a first receiving groove is provided at the bottom of the feeding track 12 corresponding to the feeding slot hole, and a feeding spring block 123 is movably arranged in the first receiving groove; a feeding extension block 124 extends upward from each of the top two ends of the feeding spring block 123; 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 124 is movably arranged through a first insertion hole; a spring cover 125 is connected to the bottom opening of the first receiving groove, and a third buffer spring 126 is provided between the bottom of the feeding spring block 123 and the top of the spring cover 125.

[0026] Each feeding extension block 124 is arranged with its upper part corresponding to a first insertion hole, that is, two feeding extension blocks 124 are respectively arranged at one end of the feeding slot. When the vibrating plate 13 transmits the scissor foot to the feeding slot through the feeding guide groove, the two feeding extension blocks 124 can limit their ends. At the same time, a third buffer spring 126 is connected between the bottom of the feeding spring block 123 and the top of the spring cover 125. In this way, when the assembly clamping plate 2832 clamps the scissor foot, it will first press down the feeding extension block 124, pressing it down into the first receiving slot (at this time, the third buffer spring 126 is in a compressed state), thereby releasing the space for the assembly clamping plate 2832 to clamp the scissor foot. That is, during the descent of the feeding extension block 124, the scissor foot will enter between the two assembly clamping plates 2832. After the assembly clamping plate 2832 clamps the scissor foot and removes it, the feeding extension block 124 will rise and reset under the drive of the restoring force of the third buffer spring 126, and so on.

[0027] Meanwhile, a spring limiting hole is provided at the bottom of the feeding spring block 123, and the upper part of the third buffer spring 126 is inserted into the spring limiting hole. The upper part of the third buffer spring 126 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 124 is provided with an outwardly inclined first guide surface 121. The function of the first guide surface 121 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.

[0028] Preferably, the top of the feeding track 12 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 122 is installed in the first mounting groove, and part of the fiber optic sensor 122 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 122. The clamping block can firmly fix the fiber optic sensor 122 in the first mounting groove, preventing the fiber optic sensor 122 from loosening or shifting during operation.

[0029] In one embodiment, the pressing and translating mechanism 15 includes a pressing mounting block 152 connected to the top of the feeding support column 14, a pressing and translating cylinder 153 mounted on the pressing mounting block 152, a pressing pull rod 154 arranged above the L-shaped horizontal end of the feeding track 12 along its length direction, and a pressing sliding plate 155 slidably arranged on one side of the top of the L-shaped horizontal end of the feeding track 12 and connected to the pressing pull rod 154; the pressing plate 151 is connected to one end of the pressing sliding plate 155. In this embodiment, a pressure plate 151 is connected to each end of the pressure sliding plate 155. Each pressure plate 151 is arranged close to a feeding slot hole. The pressure translation cylinder 153 can drive the pressure plate 151 to move above the feeding slot hole via the pressure pull rod 154 and the pressure sliding plate 155. This avoids the scissor legs from popping out due to excessive inertia after being transmitted into the feeding slot hole. At the same time, after the scissor legs are successfully transmitted into the feeding slot hole, they are moved away to facilitate the assembly clamping plate 2832 to clamp the scissor legs.

[0030] To improve the stability of the movement of the pressure plate 151, preferably, a first notch is provided on one side of the top of the L-shaped horizontal end of the feeding track 12 along its length direction, and a first linear guide assembly 156 is arranged in the first notch; the pressure sliding plate 155 is slidably connected to the first linear guide assembly 156.

[0031] To improve the smoothness of the scissor blades' movement within the feeding guide groove, preferably, a plurality of feeding air blowing assemblies 16 are also installed on the top of the feeding track 12 on one side of the feeding guide groove; each feeding air blowing assembly 16 includes an air blowing fixing block 161 and a feeding air blowing pipe 162 mounted on the air blowing fixing block 161. The feeding air blowing pipe 162 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.

[0032] 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.
