Detailed implementation manners
[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.
[0022] Embodiment: Please refer to Figures 1-6 , the present invention provides a technical solution: a keyboard keycap printing device with a positioning structure, including a workbench 1. Side plates 11 are fixedly connected to both sides of the workbench 1. A sliding rod 2 is fixedly connected between the two side plates 11. A printing table 21 is slidably sleeved on the outer side wall of the sliding rod 2. A placement groove 22 is opened at the top of the printing table 21. Four groups of positioning blocks 23 are slidably connected to the top of the printing table 21. Connecting rods 24 are fixedly connected to the sides of the positioning blocks 23 away from the placement groove 22. Push rods 25 are fixedly connected to the ends of the connecting rods 24 away from the positioning blocks 23. L-shaped rods 26 are fixedly connected to the bottoms of the push rods 25. A square block 27 is rotatably connected to the bottom of the printing table 21. A tooth block 28 is fixedly connected to the bottom of the square block 27. A rotating plate 29 is fixedly connected to the bottom of the tooth block 28.
[0023] A motor 3 is fixedly connected to the outer side wall of the side plate 11. A threaded rod 31 is rotatably connected between the two side plates 11. The printing table 21 is threadedly sleeved on the outer side wall of the threaded rod 31. The output end of the motor 3 penetrates through the side wall of the side plate 11 and is fixedly connected to the threaded rod 31. By setting the motor 3 and starting the motor 3, the motor 3 drives the threaded rod 31 to rotate between the two side plates 11, so that the threaded rod 31 drives the printing table 21 outside it to slide along the sliding rod 2, thereby adjusting the positions of the printing table 21 and the keyboard keycap.
[0024] Two limiting folding strips 4 and a rack 41 are fixedly connected between the two side plates 11. The square block 27 is slidably connected between the two limiting folding strips 4. By setting the limiting folding strips 4 and the rack 41, during the sliding connection between the square block 27 and the limiting folding strips 4, the rotating plate 29 is limited to prevent the rotating plate 29 from rotating. During the meshing connection between the tooth block 28 and the rack 41, the rack 41 drives the rotating plate 29 to rotate through the tooth block 28.
[0025] Four limiting grooves 5 are formed on the outer side of the turntable 29. Pulling blocks 51 are fixedly connected to one ends of the L-shaped rods 26 close to the turntable 29. The pulling blocks 51 are slidably connected with the limiting grooves 5. By arranging the limiting grooves 5, during the rotation of the turntable 29, under the limiting action of the limiting grooves 5, the turntable 29 pulls the four pulling blocks 51 and the four L-shaped rods 26 through the four limiting grooves 5.
[0026] Rubber blocks 6 are fixedly connected to one sides of the positioning blocks 23 close to the placement grooves 22. By arranging the rubber blocks 6, the friction between the positioning blocks 23 and the keyboard keycaps is increased, thereby improving the clamping effect of the positioning blocks 23 on the keyboard keycaps.
[0027] Four support rods 7 are fixedly connected to the outer side of the printing table 21. The push rods 25 are all slidably sleeved on the outer side walls of the support rods 7. By arranging the support rods 7, the push rods 25 are limited. During the process that the turntable 29 pulls the L-shaped rods 26 to move, the L-shaped rods 26 are prevented from shifting.
[0028] Pulling rings 8 are rotatably sleeved on the outer side walls of the pulling blocks 51. The pulling blocks 51 are all slidably connected with the limiting grooves 5 through the pulling rings 8. By arranging the pulling rings 8, the friction between the pulling blocks 51 and the limiting grooves 5 is reduced, thereby reducing the wear of the pulling blocks 51, and further improving the service life of the pulling blocks 51.
[0029] Working principle: By starting the motor 3, the motor 3 drives the threaded rod 31 to rotate through the output end. The threaded rod 31 drives the printing table 21 to slide along the sliding rod 2. The printing table 21 drives the square block 27 at its bottom to slide along the limiting folding strips 4, so that the square block 27 is separated from the two limiting folding strips 4, and the limitation on the square block 27 is released. At the same time, the square block 27 drives the tooth block 28 at its bottom to be engaged with the rack 41. Under the meshing action of the rack 41 and the tooth block 28, the rack 41 drives the turntable 29 to rotate through the tooth block 28. Under the limiting action of the limiting grooves 5, the turntable 29 pulls the four pulling blocks 51 and the four L-shaped rods 26 through the limiting grooves 5. The four L-shaped rods 26 push the connecting rod 24 to slide along the support rod 7 through the push rods 25 at their tops. The connecting rod 24 drives the positioning block 23 to slide towards the placement groove 22, so that the positioning block 23 drives the rubber block 6 to clamp on the outer side of the keyboard keycap, thereby fixing the position of the keyboard keycap in the placement groove 22. Continuing to move the printing table 21, the printing table 21 drives the tooth block 28 to be separated from the rack 41, and the square block 27 is slidably connected with the two limiting folding strips 4, thereby limiting the square block 27, the tooth block 28 and the turntable 29, preventing the turntable 29 from rotating, and further limiting and fixing the position of the keyboard keycap on the printing table 21 through the positioning block 23 until the printing table 21 drives the keyboard keycap to move to the printing position, automatically fixing the keyboard keycap on the printing table 21. The positioning process is simple and convenient, thereby improving the printing efficiency of the keyboard keycap.
