[0023] To make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0024] like Figures 1 to 5 As shown, this embodiment proposes an auxiliary tooling for keycap injection molding, including a mounting plate 1, a support plate 2 arranged at the bottom of the mounting plate 1, and adsorption components 4 arranged at both sides of the bottom of the support plate 2. Support components are also arranged on both sides of the mounting plate 1. The support components include a box body 7 arranged at both ends of the mounting plate 1, a first screw rod 5 rotatably arranged on the side wall of the box body 7, a bracket 6 threadedly arranged on the rod wall of the first screw rod 5, a support pad 601 arranged at the bottom of the bracket 6, and a slide bar 602 arranged at the top of the bracket 6. The slide bar 602 is slidably connected to the mounting plate 1. A transmission mechanism for driving the first screw rod 5 to rotate is arranged inside the box body 7, and an adjustment mechanism for adjusting the distance between two sets of relative adsorption components 4 is arranged inside the support plate 2.

[0025] The support plate 2 at the bottom of the control mounting plate 1 is moved downward so that the adsorption component 4 is against the surface of the formed keycap, and the keycap can be adsorbed, and the distance between the two groups of adsorption components 4 can be adjusted by the provided adjustment mechanism, so as to facilitate the adsorption of keycaps of different lengths. Then, the support plate 2 is controlled to move upward so that the keycap can be grabbed and transferred. When the support plate 2 moves downward, the first screw rod 5 can be driven to rotate through the transmission mechanism, and the first screw rod 5 will drive the bracket 6 to move in the opposite direction of the support plate 2 and away from the keycap. When the support plate 2 moves upward to grab the keycap, the first screw rod 5 can be driven to reverse through the transmission mechanism. At this time, the first screw rod 5 will drive the bracket 6 to move toward the support plate 2 and make the support pad 601 against the bottom edge of the keycap, so as to support the grabbed keycap and prevent the keycap from being separated from the adsorption component 4 due to shaking during the transfer process, thereby improving the stability of the keycap adsorption transfer.

[0026] Specifically, the transmission mechanism is provided with a gear 501 on the rod wall inside the box body 7, and a toothed plate 8 arranged on the top of the support plate 2 and meshing with the gear 501. A slide groove 3 is provided on the box body 7 and the mounting plate 1 for the toothed plate 8 to move up and down. When the support plate 2 moves, the gear 501 will be driven to rotate through the toothed plate 8, so the gear 501 will drive the first screw rod 5 to rotate, which can provide power for the movement of the bracket 6.

[0027] In addition, the adsorption component 4 includes a fixed cylinder 401 arranged at the bottom of the slide plate 10, a pressure rod 402 slidably arranged inside the fixed cylinder 401, a suction cup 403 arranged at the bottom of the pressure rod 402, and a spring 404 arranged between the top of the pressure rod 402 and the inner top wall of the fixed cylinder 401. A movable groove for the sliding of the fixed cylinder 401 is provided at the bottom of the support plate 2; when the support plate 2 moves downward, the suction cup 403 will be driven to resist the surface of the keycap, so that the keycap can be adsorbed, and the spring 404 can buffer the pressed suction cup 403, so that the suction cup 403 can be more stably adsorbed to the surface of the keycap.

[0028] like Figure 1 and Figure 2 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a cylinder 14 is provided at the top of the mounting plate 1, a piston rod 1401 is provided at the output end of the cylinder 14, and the bottom of the piston rod 1401 is connected to the top of the support plate 2;

[0029] The mounting plate 1 is also provided with a walking mechanism, which includes a guide rail 15, a walking trolley 16 slidably arranged on the guide rail 15, and a connecting column 1601 arranged between the walking trolley 16 and the mounting plate 1;

[0030] By starting the cylinder 14, the piston rod 1401 can be used to drive the support plate 2 to move up and down, so as to drive the suction cup 403 to contact the surface of the keycap to adsorb the keycap. After the keycap is adsorbed and picked up, the walking trolley 16 can be set to move on the guide rail 15 to transfer the picked up keycap.

[0031] like Figure 4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, the adjustment mechanism further includes a slide plate 10 slidably arranged on both sides of the inner side of the support plate 2 and a second screw rod 9 rotatably arranged on the side wall of the support plate 2, the slide plate 10 is also threadedly connected with the second screw rod 9, and the adsorption component 4 is connected to the bottom of the slide plate 10, wherein the screw holes in the two slide plates 10 that match the second screw rod 9 have opposite threaded directions;

[0032] Rotating the second screw rod 9 can drive the two groups of slide plates 10 to move relative to each other, and then drive the adsorption components 4 on both sides below the support plate 2 to move closer to or away from each other, so as to adjust the distance between the two adsorption components 4, so as to adsorb and grab keycaps of different lengths.

[0033] like Figure 2 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, a fan 11 is provided at the bottom of the support plate 2, a support air pipe 12 is provided at the output end of the fan 11, an exhaust plate 13 is provided at the air outlet end of the support air pipe 12, and an exhaust hole is opened on the lower surface of the exhaust plate 13;

[0034] When the molded keycaps are adsorbed and grabbed, the fan 11 can also be started to blow the wind into the exhaust plate 13 through the supporting air pipe 12, and then blow the wind evenly to the keycaps through the exhaust holes at the bottom of the exhaust plate 13, so as to cool the newly formed keycaps, making it easier for the keycaps to be demolded, thereby further improving the stability of the adsorption and grabbing of the keycaps.

[0035] The working principle of the utility model is as follows: the support plate 2 can be driven to move downward by the cylinder 14, so that the suction cup 403 is against the surface of the formed keycap, and the keycap can be adsorbed, and the two groups of slides 10 inside the support plate 2 can be driven to move relative to each other by rotating the second screw rod 9, so that the distance between the suction cups 403 on both sides below the support plate can be adjusted, so as to facilitate the adsorption of keycaps of different lengths. After that, the support plate 2 can be controlled to move upward to grab the keycap for transfer. When the support plate 2 moves downward, the toothed plate 8 can drive the first screw rod 5 provided with the gear 501 to rotate, and the first screw rod 5 will drive the bracket 6 to move in the opposite direction of the support plate 2 and away from the keycap. When the support plate 2 moves upward to grab the keycap, the toothed plate 8 and the gear 501 can drive the first screw rod 5 to reverse. At this time, the first screw rod 5 will drive the bracket 6 to move toward the support plate 2, and make the support pad 601 abut against the bottom edge of the keycap, so as to support the grabbed keycap and prevent the keycap from being separated from the adsorption component 4 due to shaking during the transfer process, thereby improving the stability of the keycap adsorption transfer.

Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
