Description

Technical Field

[0001] This utility model relates to the field of automatic screen printing machine technology, and more specifically, to an automatic screen printing machine positioning auxiliary device. Background Technology

[0002] LCD screens are a type of display used in digital clocks and many portable computers. During the production process, markings are screen-printed on the front or back of the screen. During mass screen printing, the markings need to be positioned to ensure consistency of the screen printing position.

[0003] A search revealed that utility model patent CN211363884U discloses an automatic screen printing machine positioning auxiliary device, including a printing platform for printing products. A support plate is fixedly connected to the rear of the printing platform, and a printing plate is movably connected to the support plate. A snap-fit ​​cover plate is fixedly mounted on the printing platform, and multiple sets of U-shaped grooves are formed on the snap-fit ​​cover plate. Positioning posts are snapped into the U-shaped grooves, and a useful connecting component is connected to the bottom of the positioning post. A driving component for achieving precise positioning is fixedly connected to the connecting component. This automatic screen printing machine positioning auxiliary device effectively positions the product to be printed by the positioning post on the printing platform. The driving component can move the positioning post to achieve precise positioning of the product, resulting in a more perfect printing effect. It not only saves time but also allows printing to be completed in one go, improving printing efficiency. However, the above patent still has the following shortcomings: it requires four motors to drive the positioning columns to position the product, which increases the difficulty of control; when screen printing the front of the display screen, it is not easy to ensure that the back of the display screen is horizontal, and the display screen placed on the printing platform is not stable and it is not easy to ensure that it is horizontal. Therefore, we have proposed an automatic screen printing machine positioning auxiliary device. Utility Model Content

The tops of the two second sliders 10 extend through the longitudinal groove 5 to the top of the placement box 3 and are fixedly connected with second clamping plates 11.

[0027] For details, please refer to Figures 1 to 4 The lifting mechanism 14 includes a telescopic groove 17 formed on the top surface of the placement box 3 and a first electric push rod 18 fixedly installed in the inner cavity of the placement box 3. The output end of the first electric push rod 18 is fixedly connected to a top column 19, and the top end of the top column 19 is movably sleeved into the inner cavity of the telescopic groove 17.

[0028] In this embodiment, the top post 19 can be made of rubber to avoid damage to the product when the top post 19 lifts the product.

[0029] For details, please refer to Figure 1 and Figure 5 The level detection mechanism 2 includes a support base 20 fixedly connected to the side of the base 1. An L-shaped rotating frame 21 is connected to the support base 20 with damping rotation. A second electric push rod 22 is fixedly installed at the end of the L-shaped rotating frame 21. A connecting plate 23 is fixedly connected to the output end of the second electric push rod 22. Multiple suspension ropes 24 are fixedly connected to the bottom surface of the connecting plate 23. A level 25 is fixedly connected to the bottom end of the multiple suspension ropes 24.

[0030] For details, please refer to Figure 1 A control panel 15 is provided at the front of the base 1, and an automatic screen printing device 16 is provided at the rear of the base 1.

[0031] In this embodiment, the screen printing machine is controlled by the control panel 15, and the automatic screen printing equipment 16 automatically screen prints the products placed on the placement box 3. This part is the prior art.

[0036] Working principle: In use, first place the LCD screen to be screen-printed on the top surface of the placement box 3. At this time, start the first motor 12 to drive the first bidirectional lead screw 6 to rotate. Through the threaded engagement between the first bidirectional lead screw 6 and the first slider 8, the two first clamping plates 9 move closer together. The first clamping plates 9 position the two sides of the display screen. At the same time, start the second motor 13 to drive the second bidirectional lead screw 7 to rotate. Through the threaded engagement between the second bidirectional lead screw 7 and the two second sliders 10, the two second clamping plates 11 move closer together. The two second clamping plates 11 position the front and back of the display screen. Then rotate the L-shaped rotating frame 21 so that the level 25 is positioned on the display screen. Above the screen, the second electric push rod 22 is activated to move the connecting plate 23, the suspension rope 24, and the level 25 downwards, so that the level 25 is placed on the display screen. At this time, the suspension rope 24 is in a slack state. The level 25 is used to detect the levelness of the display screen. Then, when the level 25 detects that the display screen is not level, one or more first electric push rods 18 are activated. The first electric push rods 18 drive the top column 19 to extend upwards. The top column 19 lifts the lower part of the display screen upwards, and at the same time, the level 25 adjusts the display screen to a level state. Finally, the automatic screen printing equipment 16 is used to screen print on the display screen.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
