Description

Technical Field

[0001] The present invention relates to the technical field of screen processing, and in particular to a printing device for processing mobile phone screens. Background Art

[0002] The mobile phone screen is also called the display screen, which is used to display images and colors. The screen size is calculated based on the screen diagonal, usually in inches, which refers to the length of the screen diagonal. The top cover glass of the mobile phone screen has black or color borders printed on it using screen printing technology. In order to improve the processing efficiency of the mobile phone screen, specific printing equipment is used to print the black or color borders on the outside of the mobile phone screen.

[0003] More specifically, when printing on a mobile phone screen, the black or color border is usually fixed on a specific film, the film is controlled to contact with the mobile phone screen, and pressure is applied, so that the black or color border on the film can be printed on the outside of the mobile phone screen. Therefore, in the process of printing the mobile phone screen, it is necessary to adjust the position of the collecting screen, the position of the printing film and the height of the printing equipment to complete the printing. However, when deviations occur in the unit links, it will cause uneven printing of the mobile phone screen, which will in turn affect the printing quality of the mobile phone screen. So far, we have proposed a printing equipment for processing mobile phone screens. Summary of the invention

[0004] In view of the shortcomings of existing printing equipment for processing mobile phone screens, the present invention provides a printing equipment for processing mobile phone screens, which has the function of automatically calibrating the position of a screen placement box by driving a rotating seat. At the same time, during the process of the second bracket driving the printing equipment to move downward, gear transmission is performed between the ratchet gear and the tooth plate, that is, the first roller automatically adjusts the winding distance of the printed film, thereby improving the convenience and accuracy of printing, and solving the problems raised in the above-mentioned background technology.

[0005] The present invention provides the following technical solution: a printing device for processing mobile phone screens, comprising a base, the upper end of the base is fixedly connected to a limiting plate, the limiting plate is internally movably sleeved with a rotating seat, the outside of the rotating seat is fixedly connected to a first bracket, the end of the first bracket is fixedly connected to a limiting sleeve, the limiting sleeve is internally movably sleeved with a limiting column, the inner side of the limiting column is fixedly connected to a screen placement box, a limiting device is arranged inside the screen placement box, a second bracket is installed at the rear end of the base through a telescopic rod, a printing device body is installed inside the lower end of the second bracket, a first roller, a second roller and a printing roller are sequentially installed on the inner side of the printing device body, one end of the middle part of the first roller is fixedly connected to a ratchet gear, the inner side of the second bracket is movably connected to a positioning column, and the outer side of the positioning column is movably sleeved with a toothed plate.

[0006] Preferably, the screen placement box is fitted on the upper part of the rotating seat, and a groove is provided at the front end of the rotating seat, and a motor is installed at the lower end of the rotating seat.

[0007] Preferably, holes are provided inside the two ends of the limiting sleeve, and a group of limiting columns are movably sleeved outside each group of holes.

[0009] Preferably, a placement slot is provided inside the screen placement box, the screen to be printed is installed inside the screen placement box, and the upper cover plate is arranged outside the upper end of the screen.

[0010] Preferably, the printing roller is arranged at the upper end of the screen placement box, and a motor is installed outside the lower end of the telescopic rod.

[0011] Preferably, a printing film is sleeved and installed on the outside of the first roller, the second roller and the printing roller, and a pressing plate is installed on the outside of the printing roller.

[0012] Preferably, a spring is installed between the second bracket and the tooth plate, the tooth plate is arranged on one side of the ratchet gear, the ratchet gear and the tooth plate are meshed and connected with each other, and the tooth plate passes through the top end of the second bracket.

[0013] Preferably, the outside of the printing device body is fixedly connected with a limit buckle, the limit buckle is arranged at the lower end of the ratchet gear, and the ratchet gear and the limit buckle are limit-connected together via ratchet teeth.

[0014] Compared with the existing printing equipment for mobile phone screen processing, the present invention has the following beneficial effects:

[0015] 1. The printing equipment for processing mobile phone screens limits the position of the side adjustment plate by the first positioning pin. The screen is installed inside the placement groove, and the upper cover is turned over. The upper cover limits the position of the screen, and the side adjustment plate is sleeved on the outside of the second positioning pin. The tension spring pulls the second positioning pin to move inward to ensure that the second positioning pin clamps and limits the position of the side adjustment plate, thereby improving the stability of the screen when it is printed and fixed.

[0016] 2. The printing equipment for processing the mobile phone screen is installed on the inner side of the limiting sleeve through the limiting column through the screen placing box, that is, the screen placing box can be rotated. By rotating the screen placing box, the screen direction can be driven, which is convenient for cutting the screen.

[0017] 3. The printing equipment for processing mobile phone screens controls the ratchet movement between the ratchet gear and the toothed plate when the second bracket is driven downward by the telescopic rod, that is, the first roller is driven to rotate, and the first roller automatically replaces the printing position of the printing film. At the same time, after the printing roller drives the printing film to be printed on the outside of the screen, the limit buckle clamps and limits the position of the ratchet gear to prevent the ratchet gear from rotating in the opposite direction. At the same time, after the telescopic rod drives the second bracket to move to the initial state, the equipment can be reset, that is, when the printing film is controlled to be pressed down for printing, the external printing position of the printing film can be automatically replaced and adjusted, thereby improving the convenience of the equipment during printing.

At the same time, when the second bracket 16 moves upward, the limit buckle 23 prevents the ratchet gear 22 from rotating, and the tooth plate 25 moves to the rear end after being subjected to pressure, preventing the first roller 18 from rotating, thereby driving the used printing film 21 to move to the printing area.

[0036] Working principle: When in use, the screen is installed in sequence inside the placement groove 14, and the side adjustment plate 10 is rotated. The side adjustment plate 10 drives the upper cover plate 11 to be installed on the outside of the screen, and the motor 4 is started at the same time. The motor 4 drives the screen placement box 8 to rotate, and the screen placement box 8 rotates to the printing area, and the telescopic rod 15 is started. The telescopic rod 15 controls the second bracket 16 to move downward, and controls the printing roller 20 to contact the screen, so that the screen can be printed. At the same time, when the second bracket 16 moves downward, the position of the tooth plate 25 is fixed, and the ratchet gear 22 and the tooth plate 25 are meshed. The external printing position of the printing film 21 can be automatically flipped, and the limit buckle 23 limits the position of the ratchet gear 22 to avoid the problem of rotation of the first roller 18.
