[0022] See also Figure 1 As shown, a 3D curved cover plate exposure fixture includes a mask plate 10, an adjustment and positioning assembly 20, an exposure platform 30, and a base 40. The mask plate 10 is above the exposure platform 30. The adjustment and positioning assembly 20 includes a positioning column 201, a positioning platform 202 and an adjusting slider 203. The adjusting slider 203 is coaxially movably sleeved in the positioning platform 202. The positioning column 201 is penetrated and sleeved in the adjusting slider 203. The mask plate 10 is connected to the positioning column 201 and positioned on the upper side of the adjusting slider 203. The exposure platform 30 is provided with a boss 301, and the boss 301 is provided with a plurality of positioning holes 3012 and grooves 3011 of different sizes. The base 40 and the exposure platform 30 are connected by a retractable cylinder 50.

[0023] In this way, the mask plate 10 is fixed by the positioning column 201 of the adjustment and positioning assembly 20, and the required exposure gap can be adjusted by adjusting the slider 203. 3D curved cover plates of different sizes can be placed on the groove 3011 of the boss 301 of the exposure platen 30. Under the action of the retractable cylinder 50 connected to the base 40, the exposure platen 30 rises to the exposure position during exposure so that the boss 301 on the exposure platen 30 fits with the positioning table 202 of the adjustment slider 20, and exposure is performed. After the exposure is completed, it descends to the specified position, thereby meeting the requirements for 3D curved surface exposure patterns of different sizes.

[0024] In this embodiment, at least one group of adjusting and positioning components 20 is evenly and symmetrically distributed around or on both sides of the boss 301 of the exposure platform 30, so that when the telescopic cylinder lifts the exposure platform to the exposure position, it can better fit with the adjusting and positioning components, and when the adjusting slider is adjusted, the flatness of the exposure surface can be achieved.

[0025] It should be noted that the adjustment and positioning assembly 20, the positioning platform 202 and the adjustment slider 203 in this embodiment can be connected in a variety of ways.

[0026] In one embodiment, the interior of the positioning platform 202 is connected to the exterior of the adjusting slider 203 via an adjusting screw, so that the adjusting slider 203 can be screwed in and out of the positioning platform 202, so that the adjusting slider 203 can be adjusted according to the actual required height, and is also convenient for disassembly and replacement.

[0027] In one embodiment, the interior of the positioning platform 202 is connected to the screw rod of the adjusting slider 203, the fixed end of the screw rod is fixedly connected to the bottom of the positioning platform 202, and the telescopic end of the screw rod abuts against the bottom of the adjusting slider 203. In this way, the up and down adjustment and disassembly of the adjusting slider 203 can be achieved through the up and down movement of the screw rod.

[0028] In this embodiment, the adjustment and positioning assembly 20 further includes a distance sensor for detecting the flatness and height of the top surface of the adjustment slider 203 to meet the requirements of the exposure gap.

[0030] In one implementation of the present embodiment, a through hole or a slot corresponding to the outer diameter of the positioning post 201 is provided at the edge of the mask plate 10 , so that the positioning post 201 can be inserted or snapped into place.

[0031] It should be noted that the mask plate 10 and the positioning pillars 201 may also be fixed by means of a pressing sheet or a nut.

[0032] In one implementation of the present embodiment, the height of the positioning platform 202 is consistent with the height of the boss 301 on the exposure platform 30 , which can better fit the gap control between the boss 301 and the adjustment slider 203 .

[0033] In one implementation of the present embodiment, the positioning holes 3012 are vacuum adsorption holes that penetrate the boss 301 and are evenly distributed in each groove 3011 . The positioning holes 3012 are connected to an external vacuum pipeline to stably and evenly adsorb the exposed part placed in the groove 3011 .

[0034] In one embodiment, one end of the telescopic cylinder 50 is fixedly connected to the base 40 , and the other end is elastically connected to the exposure platform 30 , so that the exposure platform 30 can be pushed closer to or pulled away from the mask plate 10 as the telescopic cylinder 50 is extended or retracted.

[0035] Through the structural design of the exposure table, the utility model can make the clamp suitable for exposed parts of different sizes. By adjusting the structure and connection design of the positioning column, the positioning table and the adjusting slider of the positioning component, the mask plate can be better positioned and the exposure gap can be flexibly adjusted, so that the gap between the mask plate and the exposed part meets the requirements, and the exposure needs of different exposure patterns can be met.
