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

[0015] Reference Figures 1 to 4As shown, this utility model provides a feeding platform device for an automatic keyboard scissor-switch assembly machine. In one embodiment, it includes an installation platform 1; a first support bar 2 is provided on each of the two sides of the top of the installation platform 1 along the length of the installation platform 1; a second support bar 3 is also provided on one side of each of the first support bars 2, and the height of the first support bar 2 is higher than that of the second support bar 3; a first translation mechanism 4 and a second translation mechanism 5 are also installed in the middle of the top of the installation platform 1; the first translation mechanism 4 is driven to connect a first sliding plate 41, and the bottom two ends of the first sliding plate 41 are respectively slidably connected to a first support bar 2; a first support seat 42 for carrying products is also installed on the top of the first sliding plate 41; the second translation mechanism 5 is driven to connect a second sliding plate 51, and the bottom two ends of the second sliding plate 51 are respectively slidably connected to a second support bar 3; a first lifting mechanism is installed on the second sliding plate 51, and the first lifting mechanism is also driven to connect a second support seat 52 for carrying products.

[0016] In this embodiment, a first lifting ring 11 is connected to each of the four top corners of the mounting platform 1 to facilitate the transport of the device, and a foot cup is installed at each of the four bottom corners of the mounting platform 1 to ensure that the mounting platform 1 can be placed stably on the workbench; the first translation mechanism 4 and the second translation mechanism 5 can respectively drive the first sliding plate 41 and the second sliding plate 51 to move, so that the first support seat 42 or the second support seat 52 carrying the keyboard frame can be moved to the predetermined assembly position, and then the scissor legs are assembled to the corresponding positions of the keyboard frame by an external assembly mechanism. The height of the first support bar 2 is higher than that of the second support bar 3, so that the first sliding plate 41 itself is higher than the second sliding plate 51, and the second sliding plate 51 is also equipped with a first lifting mechanism, which can drive the first sliding plate 41 to move the first sliding plate 41 to move the second sliding plate 51 to move the first sliding plate 41 to move the second sliding plate 51 to move the first sliding plate 41 to move the second sliding plate 51 to move the first sliding plate 41 to move the second sliding plate 51 to move the second ... The second support seat 52 descends below the first sliding plate 41, forming a clearance to facilitate the movement of the first support seat 42. At the same time, the first lifting mechanism can also drive the second support seat 52 to rise to a preset height, facilitating the assembly of the scissor legs. This double-layer layout allows for seamless and free switching between the first support seat 42 and the second support seat 52, enabling continuous material supply without stopping the machine (one support seat moves to the assembly position for assembling the scissor legs, while the other support seat moves to the loading position to wait for the robot arm to transfer the assembled keyboard frame for unloading, and simultaneously transfer the keyboard frame to be assembled onto the support seat). This greatly improves work efficiency and reduces the floor space required. Furthermore, a single set of scissor leg assembly mechanisms can be shared, thereby reducing costs.

[0017] Preferably, in this embodiment, a first guide hole is provided at the top center of the mounting platform 1 along the length direction of the mounting platform 1, and a first connecting vertical plate 43 is driven and connected to the first translation mechanism 4; the lower part of the first connecting vertical plate 43 is arranged through the first guide hole, and a first connecting horizontal plate 44 is also connected to the bottom of the first connecting vertical plate 43; the first connecting horizontal plate 44 is located below the mounting platform 1, and a second connecting vertical plate 45 is connected to each of the top two ends of the first connecting horizontal plate 44; a second guide hole is provided on each of the top two sides of the mounting platform 1 along the length direction of the mounting platform 1, and the upper part of the second connecting vertical plate 45 is arranged through the second guide hole; a first slide rail assembly is also arranged at the top of each first support bar 2, and the bottom two ends of the first sliding plate 41 are slidably arranged on a first slide rail assembly, and the two ends of the first sliding plate 41 are respectively connected to a second connecting vertical plate 45.

[0018] The first translation mechanism 4 adopts a motor lead screw transmission method, which can drive the first sliding plate 41 to move via the first connecting vertical plate 43, the first connecting horizontal plate 44 and the second connecting vertical plate 45, thereby moving the first bearing seat 42 to the assembly position or the loading position. At the same time, a first slide rail assembly is provided to ensure its sliding stability.

[0019] In one embodiment, a second slide rail assembly is further arranged at the top of each of the second support bars 3, and the bottom ends of the second sliding plate 51 are each slidably arranged on a second slide rail assembly; the second translation mechanism 5 is also driven and connected to a third connecting vertical plate 53, and the third connecting vertical plate 53 is connected to the bottom of the second sliding plate 51. The second translation mechanism 5 adopts a motor screw transmission method, which can drive the second sliding plate 51 to move along the second slide rail assembly via the third connecting vertical plate 53, so that the second bearing seat 52 moves to the assembly position or the loading position. At the same time, the first lifting mechanism includes two first lifting cylinders 54; the two first lifting cylinders 54 are respectively installed at one end of the second sliding plate 51, and the bottom of the second bearing seat 52 is connected to the output shaft of the first lifting cylinder 54. Two first lifting cylinders 54 can drive the second support seat 52 to rise and fall, forming a clearance to facilitate the passage of the first support seat 42. At the same time, they can also drive the second support seat 52 to rise to a preset height to facilitate the assembly of the scissor legs. In addition, to improve the stability of the second support seat 52's rise and fall, a first through hole is opened at each of the four corners of the second sliding plate 51, and a slide rail fixing block 55 is connected to one side of the inner wall of the first through hole. A third slide rail assembly is also arranged on one side of the slide rail fixing block 55 along the vertical direction. A fourth connecting vertical plate 56 is connected to each of the four bottom corners of the second support seat 52, and each fourth connecting vertical plate 56 is slidably arranged on a third slide rail assembly. A first limiting rod 57 is also connected between the two fourth connecting vertical plates 56 located at the same end of the second support seat 52, and a first buffer 58 is also installed on the top of the first limiting rod 57.

[0020] In one embodiment, a first clamping cylinder 511 is also installed at the bottom of the second sliding plate 51 along the width direction of the second sliding plate 51, and the first clamping cylinder 511 is also driven to connect two balance support bars 512; a third guide hole is also provided at the top of the second sliding plate 51 along the width direction of the second sliding plate 51, and the balance support bars 512 are movably arranged in the third guide hole; a balance support plate 513 is also connected at the bottom of the second bearing seat 52 corresponding to the balance support bars 512. In this embodiment, two sets of first clamping cylinders 511 are arranged in parallel at intervals at the bottom center of the second sliding plate 51. The bottom of the second bearing seat 52 is connected to a balance support plate 513. After the second bearing seat 52 is lifted into position, the first clamping cylinder 511 drives the balance support bar 512 to move to the bottom of the balance support plate 513 to support it, thereby supporting the side of the bottom surface of the second bearing seat 52, so that the supporting force supporting the second bearing seat 52 is balanced and its placement is stable. When the second bearing seat 52 is lowered and reset, the first clamping cylinder 511 needs to drive the two balance support bars 512 to move towards each other, thereby moving away from the bottom of the balance support plate 513 to form a clearance. During the descent of the second bearing seat 52, the balance support plate 513 will pass through one end of the third guide hole. At the same time, a support block is connected to the middle part of the inner wall of the third guide hole, and the balance support bar 512 is partially arranged on the support block to support the balance support bar 512.

[0021] In one embodiment, both the first support base 42 and the second support base 52 include a support base plate 521, and the top of the support base plate 521 extends upward with a support boss 522; the top of the support boss 522 is provided with a plurality of feeding positions at intervals along its length, and each feeding position is provided with a product limiting block 523 on one side and one end; a positioning pin 524 is also installed on the feeding position.
