[0034] In some embodiments, referring to Figure 2 as shown in Figure 2 The structural schematic diagram of the hanging basket 100 of the screen plate automatic cleaning device 10 according to an embodiment of the present utility model. The hanging basket 100 includes a bottom plate 110, side plates 120, and a top plate 130. The bottom plate 110 and the top plate 130 are oppositely arranged, and opposite side plates 120 are arranged between the bottom plate 110 and the top plate 130. A plurality of limiting grids 150 are respectively arranged on the bottom plate 110 and the top plate 130.

[0037] In some of these embodiments, the edge of the side plate 120 has a clamping groove 121. The pressing rod 140 can be embedded in the clamping groove 121 to achieve a locking connection with the side plate 120.

[0038] In some of these embodiments, a plurality of hanging holes 122 are provided on each side plate 120. The hanging holes 122 are used for connecting the moving mechanism 200 and the hanging basket 100.

[0039] In some of these embodiments, the moving mechanism 200 includes a hook 210, a hook seat 220, a guide rail 230, a translation driving component 240, and a lifting driving component 250. The guide rail 230 extends along the distribution direction of the ultrasonic cleaning tank 300, the pure water cleaning tank 400, and the air drying tank 500. The hook seat 220 is slidably connected to the guide rail 230, and the translation driving component 240 is installed on the guide rail 230 and connected to the hook seat 220. The translation driving component 240 is used to drive the hook seat 220 to translate. The lifting driving component 250 is installed on the hook seat 220 and connected to the hook 210. The lifting driving component 250 is used to drive the hook 210 to move up and down. The hook 210 automatically extends its hook claws into the hanging holes 122. The hook 210 can be a hook claw with power, and the hook 210 can perform a hooking action under the drive of the control mechanism.

[0040] In some of these embodiments, the ultrasonic cleaning tank 300, the pure water cleaning tank 400, and the air drying tank 500 are arranged adjacent to each other. The guide rail 230 is located above the ultrasonic cleaning tank 300, the pure water cleaning tank 400, and the air drying tank 500 to facilitate the hook 210 to transfer the hanging basket 100 between the ultrasonic cleaning tank 300, the pure water cleaning tank 400, and the air drying tank 500.

[0044] When the above-mentioned screen plate automatic cleaning device 10 is used for cleaning the screen plate 20, it includes the following steps:

[0045] (1) The operator vertically places multiple stencils 20 into the limiting grooves of the hanging basket 100. The multiple stencils 20 are distributed at intervals. At the same time, the pressing rod 140 on the side plate 120 is rotated and inserted into the clamping groove 121 on the side plate 120 to lock the stencil 20, so as to fix the multiple stencils 20 in the hanging basket 100. The operator assists in placing the hanging basket 100 at the loading station 610.

[0046] (2) Control the translation drive component 240 to drive the hook seat 220 to translate above the loading station 610, and control the lifting drive component 250 to drive the hook 210 to descend onto the hanging basket 100.

[0047] Control the hook 210 to extend into the lifting hole 122 on the side plate 120 of the hanging basket 100 to ensure the stability of the hanging basket 100. After the hanging basket 100 is hooked, control the lifting drive component 250 to drive the hook seat 220 to drive the hook 210 and the hanging basket 100 to rise. Control the translation drive component 240 to drive the hook seat 220 to translate to the position of the ultrasonic cleaning tank 300. After reaching the position, control the lifting drive component 250 to drive the hook 210 and the hanging basket 100 to descend, and the hanging basket 100 enters the ultrasonic cleaning tank 300 for the first ultrasonic ethanol cleaning.

[0048] (3) After the first cleaning is completed, control the lifting drive component 250 to drive the hook seat 220 to drive the hook 210 and the hanging basket 100 to rise. Control the translation drive component 240 to drive the hook seat 220 to translate to the position of the pure water cleaning tank. After reaching the position, control the lifting drive component 250 to drive the hook seat 220 to descend and drive the hook 210 and the hanging basket 100 to descend, and the hanging basket 100 enters the pure water cleaning tank for the second pure water cleaning.

[0049] (4) After the second cleaning is completed, control the lifting drive component 250 to drive the hook seat 220 to drive the hook 210 and the hanging basket 100 to rise. Control the translation drive component 240 to drive the hook seat 220 to translate to the position of the air drying tank 500. After reaching the position, control the lifting drive component 250 to drive the hook seat 220 to drive the hook 210 and the hanging basket 100 to descend, and the hanging basket 100 enters the air drying tank 500. Control the fan to work. After air drying is completed, control the lifting drive component 250 to drive the hook seat 220 to drive the hook 210 and the hanging basket 100 to rise. Control the translation drive component 240 to drive the hook seat 220 to translate to the unloading station 620. The operator takes out the cleaned stencil 20 from the unloading station 620, and the cleaning of the stencil 20 ends; then the next round of stencil 20 cleaning can be carried out.

[0050] It should be noted that the above control actions can be completed by a control mechanism connected electrically. Among them, the control mechanism can be a PLC programmable logic controller.

[0051] In summary, the above-mentioned automatic screen cleaning device 10 has high cleaning efficiency. By setting up the ultrasonic cleaning tank 300, pure water cleaning tank 400 and air drying tank 500, the drawbacks of manual screen cleaning are eliminated. Multiple screens 20 can be cleaned simultaneously in one cleaning process, saving labor. Automatic cleaning reduces the wear of the screen 20 and increases its service life. At the same time, the probability of screen explosion during the cleaning process is reduced.
