In this embodiment, the inflatable telescopic member 12 can be extended and retracted according to the amount of inflation, and the push plate 13 is tightly attached to the inner wall of the material storage box 11, so that the resin liquid under the push plate 13 can be completely pushed out of the liquid outlet 16; through the adjusting clamps 25 on the first adjusting plate 22 and the second adjusting plate 23, it can be adjusted within a certain range according to the model requirements of the resin plate, which is suitable for application scenarios with the same type of plate making requirements.

[0032] In this embodiment, a fixing groove 251 is provided at one end of the adjusting clamp 25 for fixing on the adjusting plate; a clamping groove 252 is provided at the other end of the adjusting clamp 25 for fixing the glass plate 24; through the setting of the fixing groove 251 and the supporting groove, the adjusting clamp 25 can be inserted into and removed from the adjusting plate, and it also plays a role in fixing the connection between the glass plate 24 and the adjusting plate, and has strong flexibility.

[0033] In this embodiment, the positioning tube 18 is connected to a liquid outlet nozzle 19, the shape of the liquid outlet nozzle 19 matches the liquid inlet 221, a positioning block 191 is provided on the liquid outlet nozzle 19, and limit blocks 192 are provided on both sides of the positioning block 191.

By setting the valve 181, the flow rate and flow velocity of the resin liquid can be controlled in conjunction with the discharging device. Bubbles are usually generated when the resin surface or substrate contacts the resin, especially when the resin is laid too fast or the flow is not smooth. The resin gradually flows in from one side, which can reduce violent disturbances and reduce the probability of bubble generation, thereby controlling the resin liquid and the liquid level, and improving the platemaking effect after molding. When the resin flows in from the bottom, the flow of the resin can be relatively gentle, avoiding the phenomenon of uneven coating caused by too fast laying. The natural expansion of the flow can help the resin to be evenly distributed on the substrate.

The operator can adjust the relative position of the adjustment clamp 25 according to the scale 231 on the second adjustment plate 23 to achieve the effect of controlling the target size of the resin plate, reduce material waste and improve utilization.

[0041] Step 1, build the adjustment plate and the glass plate 24 on the base plate 21, then adjust the adjustment clamp 25 on the second adjustment plate 23 according to the actual required width, move it to the target position according to the scale 231 on the second adjustment plate 23, then move the adjustment clamp 25 on the first adjustment plate 22 to be level with the adjustment clamp 25 on the second adjustment plate 23, and then put the glass plate 24 into the clamping groove 252;

[0042] Step 2, placing the upper end of the intercepting plate 227 on the intercepting block 228, the height of the intercepting block 228 being equal to or greater than the height of the liquid inlet 221, so that the liquid inlet 221 remains in an open state;

[0043] Step 3, insert the liquid outlet nozzle 19 on the positioning tube 18 into the liquid inlet 221, and fix the positioning block 191 and the limiting block 192 on the liquid outlet nozzle 19 into the positioning groove 222 and the limiting groove 223 respectively, and then move the limiting rod 224 to a vertical position;

[0044] Step 4, turn on the air pump 14, the inflatable telescopic member 12 moves downward after being inflated, driving the push plate 13 to make the liquid resin in the storage box 11 flow out of the liquid outlet 16, enter the positioning tube 18, and then flow into the liquid inlet 221 at the bottom of the first adjustment plate 22, gradually reaching the target position from bottom to top, and then turn off the air pump 14;

[0046] In this embodiment, the resin flows in from one side of the bottom layer, and gravity can be used to make the resin flow naturally to other areas, which helps the resin to diffuse naturally on the surface of the substrate, thereby reducing the possibility of bubbles or local accumulation. The resin on one side that flows in will be pushed by gravity and diffuse evenly to the other side, which can avoid excessive resin accumulation in some areas and uneven accumulation in other areas.
