They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0022] Reference Figure 1-3 As shown, this embodiment provides an automatic silk-screen printing auxiliary device for airbags. The automatic silk-screen printing auxiliary device is provided with a loading area, a silk-screen printing area, and a unloading area from left to right. The loading area includes an upper positioning tool 1 and a lower positioning tool 2. The upper positioning tool 1 and the lower positioning tool 2 are both conveyed in and out via double tracks. A supporting cylinder is further provided at the bottom of the lower positioning tool 2, and the supporting cylinder is used to support the lower positioning tool 2 to move up and down.

[0023] The screen printing area includes a screen printing mechanism 4 and a slide rail 3. The screen printing mechanism 4 is slidably connected to the slide rail 3. The slide rail 3 is slidably connected to the lifting rail. Both ends of the slide rail 3 are also slidably provided with a screen fixing mechanism. The screen fixing mechanism includes a drive motor and a screen clamp 5. The drive motor is used to control the sliding of the screen clamp 5 along the slide rail 3. The screen clamp 5 is used to clamp the screen on the printing position.

[0024] The unloading area includes an unloading mechanism and a plasma wind rod. The unloading mechanism is used to transfer the screen from the printing position to the stacking mechanism. The plasma wind rod is located on both sides of the printing position.

[0025] By setting up the loading area, screen printing area and unloading area, the fully automatic working processes of loading, screen printing and unloading are realized respectively. Secondly, by setting up the upper positioning tool 1 and the lower positioning tool 2 in the loading area, and then cooperating with the supporting cylinder, the two sets of positioning tooling are cross-operated, which greatly improves the screen printing efficiency. Finally, by installing a plasma wind bar in the unloading area, the static electricity of the screen-printed material is eliminated, avoiding the situation of over-taking of materials in the unloading mechanism.

[0026] Furthermore, the screen printing mechanism 4 includes an oil knife and a scraper. The oil knife is in vertical contact with the screen, and the scraper is in inclined contact with the screen at an angle of 45°.

[0027] Furthermore, the automatic silk screen printing auxiliary device is also provided with an ink adding mechanism, which is used to add ink to the screen when there is less ink on the screen or the silk screen printing is not clear.

[0028] By setting up an ink-adding mechanism, it is achieved that when there is less ink on the screen or the silk-screen printing is not clear, the number of ink squeezing times and the squeezing time of the ink-adding mechanism can be set according to experience. In this embodiment, the ink-adding mechanism is a common mechanism on the market, and it is not improved in this embodiment. Therefore, the ink-adding mechanism can be a mechanism that extracts ink from the ink cartridge through a pump and replenishes ink through a delivery pipe, or it can be any mechanism that can achieve ink replenishment.

[0029] Furthermore, protective gratings 6 are provided on both sides of the automatic silk screen auxiliary device.

[0030] By setting up the protective grating 6, the side protective grating 6 can prevent people from approaching the mobile device when the device is working normally, preventing casualties. When the screen is dirty, people can enter the device to wipe the ink. When the protective grating 6 under the frame senses an object, the entire device can be directly cut off to prevent the device from continuing to operate and injuring people.

[0031] Furthermore, the automatic screen printing auxiliary device is also provided with a touch screen, and the touch screen is provided with a control main switch, and the control main switch is used to control all driving motors of the automatic screen printing auxiliary device.

[0032] Furthermore, the unloading mechanism includes a negative pressure suction cup and a unloading guide rail. The negative pressure suction cup is installed at the bottom of the unloading tray, and both ends of the unloading tray are slidably connected to the unloading guide rail.

[0033] The working principle of this utility model:

[0034] First, fix the screen at the printing position, and use the drive motor to drive the screen clamp 5 to adjust the screen to the center position, then adjust the scraper and oil knife on the screen printing mechanism 4 to fully contact the screen, and then manually load the material to the upper positioning tool 1, and then press the start button on the touch screen to move the upper positioning tool 1 to the printing position, and at the same time, move the lower positioning tool 2 to the manual loading position, and start loading the material to the lower positioning tool 2. At the same time, the motor of the lifting track controls the screen to descend and contact the material, and the oil knife also descends to contact the screen, and evenly pushes the ink on the screen to the right, and then the oil knife moves up. The screen rises, the scraper descends, and scrapes from the right to the left at a 45-degree angle with uniform force, allowing the ink to be transferred to the material through the blank holes in the pattern part. After printing is completed, the screen is raised by the motor of the lifting track, and the unloading mechanism automatically moves to the printing position, and the material is taken away and placed on the stacking mechanism. While the unloading mechanism is taking the material, the plasma wind rod will perform static elimination to prevent excessive material from being taken due to electrostatic adsorption of the material. Then the upper positioning tool 1 is automatically moved out, and the lower positioning tool 2 moves to the printing position with the material, and then the material is manually loaded to the upper positioning tool, and the cycle is repeated.

[0035] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
