Technical Field

[0001] The utility model belongs to the technical field of keyboard keycap processing, and in particular relates to a keycap silk screen printing device for keyboard printing. Background Art

[0002] The main components of the keyboard are keycaps of various shapes. The keycaps are silk-screened when the manufacturer uses a font template to print characters on the keycaps, and then uses a special silk screen to brush a layer of plastic to form a plastic protective film covering the printed characters.

[0003] The existing keyboard keycap silk screen printing device, when silk screen printing the keycap, needs to first place the keycap in the printing mold, then send the printing mold to the bottom of the silk screen printing device through the transfer mechanism, wait for the silk screen printing to be completed, and then take the keycap out of the printing mold for the next step of drying. However, this method makes it impossible to work continuously, and the keycap loading and unloading time is separated from the silk screen printing process, resulting in a long overall keycap processing time, low work efficiency, and increased processing costs. For this reason, we propose a keyboard keycap silk screen printing device. Utility Model Content

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-Figure 4 The utility model provides a keycap screen printing device for keyboard printing, comprising a base 1, a processing box 2 is arranged in the middle of the upper surface of the base 1, a moving mechanism 3 is arranged inside the base 1, the moving mechanism 3 comprises a motor 301, and the motor 301 is arranged on the left outer surface of the base 1 through a motor seat, the power output end of the motor 301 is connected to a threaded rod 302 through a coupling transmission, the circumferential surface of the threaded rod 302 is threadedly connected to a moving block 303, and the upper surface of the moving block 303 is provided with a moving seat 304;

[0019] It should be noted that a moving groove is provided at the upper end of the base 1, and the moving block 303 is arranged inside the moving groove, which can limit the moving block 303 and enable the moving block 303 to move horizontally left and right smoothly.

[0020] Printing molds 305 are provided on both sides of the upper surface of the movable seat 304, and track plates 306 are provided on both sides of the front and rear of the two printing molds 305. Counterweight sealing plates 307 are movably installed inside the lower ends of the left and right sides of the processing box 2, and the lower ends of the counterweight sealing plates 307 abut against the upper surface of the movable seat 304. Movable grooves 4 are provided inside the left and right sides of the processing box 2, and the upper ends of the two counterweight sealing plates 307 are respectively arranged inside the two movable grooves 4, and rollers 308 are rotatably installed on both ends of the left and right sides of the two counterweight sealing plates 307.

[0021] It should be noted that the front roller 308 is on the same horizontal line as the front track plate 306, and the rear roller 308 is on the same horizontal line as the rear track plate 306, so that when the movable seat 304 drives the track plate 306 to move horizontally left and right, the roller 308 can roll on the upper surface of the track plate 306, and the track plate 306 is trapezoidal in shape. When the movable seat 304 drives the track plate 306 to move horizontally, the roller 308 will roll on the track plate 306 and gradually move upward, driving the counterweight sealing plate 307 to move upward, thereby opening the side wall of the processing box 2, so that the printing mold 305 can be smoothly moved out of the processing box 2 and moved into the processing box 2. Then, when the other side of the track plate 306 contacts the roller 308, the counterweight sealing plate 307 and the roller 308 gradually move downward under the action of their own weight, thereby timely closing the side wall of the processing box 2, which is convenient for the silk screen printing of the keycaps.

[0022] An air pump 6 is provided on the upper surface of the processing box 2, and an air intake pipe 7 is provided at the front end of the air pump 6, and the air intake pipe 7 is an inverted U-shaped setting, and the air intake ports on the left and right sides of the air intake pipe 7 are respectively located above the two counterweight sealing plates 307. Because organic solvents may be used in the silk-screen printing process of the keycaps, these solvents will produce organic waste gas when they evaporate. Therefore, after using the organic solvent, first connect the exhaust port of the air pump 6 to the waste gas treatment device, and then when the counterweight sealing plate 307 on the side wall of the processing box 2 is opened and closed, the air pump 6 is turned on, and the gas inside the processing box 2 is extracted through the air intake pipe 7. At the same time, the outside gas enters through the opening of the side wall of the processing box 2, so that an inward airflow is generated at the opening of the processing box 2, so that the gas inside the processing box 2 will not flow out from the opening, thereby avoiding organic waste gas from floating in the working environment and causing pollution.

[0023] In this embodiment, preferably, a screen printing mechanism 5 is provided inside the processing box 2, and the screen printing mechanism 5 includes a lifting cylinder 501, and the lifting cylinder 501 is arranged on the inner top wall of the processing box 2, and a lifting plate 502 is provided at the lower end of the lifting cylinder 501, and a screen printing plate 503 is provided inside the lifting plate 502, and a motor 2 504 is provided at the left end of the rear side of the lifting plate 502 through a motor seat, and a power output end of the motor 2 504 is transmission-connected with a threaded rod 2 505, and the circumferential surface of the threaded rod 2 505 is threadedly connected with a moving block 2 506, and a scraper 507 is provided at the right end of the moving block 2 506, and the lower end of the scraper 507 abuts against the upper surface of the screen printing plate 503;

[0024] It should be noted that the inner walls on both sides of the lifting plate 502 are provided with sliding grooves, and the interior of the sliding grooves is provided with moving blocks 506. The two moving blocks 506 are respectively connected to the left and right ends of the scraper 507, so that the scraper 507 is positioned by the moving blocks 506 on both sides. Then when the motor 504 drives the threaded rod 505 to rotate, the moving blocks 506 can smoothly drive the scraper 507 to move horizontally back and forth, exerting pressure on the upper surface of the silk screen plate 503, so that the ink is squeezed on the screen and transferred to the key caps through the mesh holes, thereby realizing the silk screen printing of the key caps.

[0025] The working principle and use process of the utility model are as follows: when it is necessary to screen print the keyboard keycaps, the keyboard keycaps have been placed inside the left printing mold 305, and the lifting cylinder 501 is started, and the lifting cylinder 501 drives the lifting plate 502 and the screen printing plate 503 to move downward, so that the screen printing plate 503 moves to the upper end of the printing mold 305, and then the motor 2 504 is started to rotate the threaded rod 2 505, and then drives the moving block 2 506 and the scraper 507 to move horizontally back and forth, and exerts pressure on the upper surface of the screen printing plate 503, so that the ink is squeezed on the screen and transferred to the keycaps through the mesh, so as to realize the screen printing of the keycaps, and at the same time, the staff places the next keyboard keycap waiting for screen printing inside the right printing mold 305;

[0026] After the screen printing of the keyboard keycaps inside the left printing mold 305 is completed, the motor 301 is started, and the motor 301 drives the threaded rod 302 to rotate, so that the moving block 303 drives the moving seat 304 and the printing mold 305 to move horizontally to the left. When the moving seat 304 moves horizontally to the left, the track plate 306 will first contact the roller 308, so that the track plate 306 drives the roller 308 to move upward during the movement to the left, and then the roller 308 drives the counterweight sealing plate 307 to move upward and open the left and right sides of the processing box 2. At this time, the moving seat 304 continues to move to the left, and the printing mold 305 on the left is smoothly moved out of the processing box 2, and the printing mold 305 on the right is smoothly moved into the processing box 2, completing the replacement of the two printing molds 305, and then the keyboard keycaps inside the right printing mold 305 are screen-printed, and the printing mold 305 on the left is used to take out the keyboard keycaps and put in new ones.
