[0034] Specifically, the machine table 10 is the basic structure of the exposure device 100, and can provide a stable and reliable setting position for the tensioning assembly 20 and the glass clamping assembly 30. The tensioning assembly 20 can be used to tension the material 200 on the front and rear two sets of take-up and pay-off devices, so as to ensure that the material 200 is unfolded and flattened in the exposure device 100. In the embodiments of the present application, the tensioning assembly 20 is two, and the two tensioning assemblies 20 are respectively arranged at the two ends of the machine table 10 in the first direction, so as to ensure that the material 200 is supported at the two ends of the exposure device 100 in the first direction, so that the material 200 can be unfolded and fixed on the exposure device 100.
[0035] Further, the glass clamping assembly 30 is arranged on the machine table 10 and located between the two tensioning assemblies 20, and the glass clamping assembly 30 includes an upper glass clamping piece 31 and a lower glass clamping piece 32. The upper glass clamping piece 31 and the lower glass clamping piece 32 are arranged opposite to each other, and when the material 200 is unfolded on the exposure device 100, the lower glass clamping piece 32 can support the material 200 in the up-down direction, and the upper glass clamping piece 31 can press the material 200 downward, so that the material 200 on the exposure device 100 can be clamped by the upper glass clamping piece 31 and the lower glass clamping piece 32 together, so as to ensure that the material 200 is arranged flat in the exposure area, so as to ensure the exposure quality.
[0036] In the embodiments of the present application, the exposure area of the exposure device 100 corresponds to the position of the glass clamping assembly 30.
[0037] Further, one end of the upper glass clamping piece 31 is rotatable upward relative to the lower glass clamping piece 32. In this way, on the one hand, the upper glass clamping piece 31 can be rotated upward to facilitate cleaning of the upper glass clamping piece 31, and on the other hand, when the exposure of the material 200 is completed, the upper glass clamping piece 31 can be rotated relative to the lower glass clamping piece 32, so that the upper glass clamping piece 31 cancels the limiting of the material 200, and the material 200 can move along the first direction on the exposure device 100, so that the two roll feeding and unwinding devices before and after the exposure device 100 complete the material feeding work to update the material 200 to be exposed.
[0038] In the embodiment of the utility model, after the upper glass clamping piece 31 is rotated upward relative to the lower glass clamping piece 32, the upper glass clamping piece 31 can be rotated downward relative to the lower glass clamping piece 32 to clamp the upper glass clamping piece 31 and the lower glass clamping piece 32 again.

The first driving piece 41 can convert electric power into torque and output under the condition of power supply. The shaft 42 is connected to the first driving piece 41 through a shaft coupling 45, and the end of the shaft 42 away from the first driving piece 41 is fixed on the machine table 10 through a belt seat bearing 46. The connecting block 43 is located in the region between the shaft coupling 45 and the belt seat bearing 46 in the first direction of the shaft 42, so that the torque of the first driving piece 41 can be transmitted to the shaft 42 to make the shaft 42 rotate, and the connecting block 43 can drive the upper glass clamping piece 31 to rotate relative to the lower glass clamping piece 32 to selectively open and close the glass clamping assembly 30.
[0042] Further, the connecting blocks 43 are arranged on the rotating shaft 42, and rotate synchronously with the rotating shaft 42 when the rotating shaft 42 rotates. One end of the upper glass clamping member 31 is connected with the connecting blocks 43, so that the upper glass clamping member 31 can be driven to rotate by the connecting blocks 43 when the rotating shaft 42 rotates, and the first driving member 41 can drive the upper glass clamping member 31 to rotate relative to the lower glass clamping member 32, so that the glass clamping assembly 30 can selectively clamp the material 200.
[0043] As shown in Figure 6 The connecting blocks 43 are arranged on the rotating shaft 42, and rotate synchronously with the rotating shaft 42 when the rotating shaft 42 rotates.

The connecting blocks 43 are arranged along the length direction of the rotating shaft 42, so that the force of the connecting blocks 43 on the upper glass clamping member 31 can be evenly distributed along one end of the upper glass clamping member 31.
[0045] In this way, on the one hand, the connection reliability of one end of the upper glass clamping member 31 and the rotating shaft 42 can be ensured, so that the arrangement reliability of the upper glass clamping member 31 on the exposure device 100 can be ensured.
[0046] On the other hand, when the rotating shaft 42 rotates, the connecting blocks 43 can simultaneously apply force to the upper glass clamping member 31 along the length direction of the rotating shaft 42, so as to drive the upper glass clamping member 31 to rotate about the rotating shaft 42 as the rotation axis and stably rotate relative to the lower glass clamping member 32. In this way, when the upper glass clamping member 31 rotates relative to the lower glass clamping member 32, the upper glass clamping member 31 can timely and completely separate from the material 200 on the lower glass clamping member 32, so that the reliability of the position of the material 200 being movable can be ensured.

The second sealing ring 324 is arranged between the lower glass piece 322 and the lower frame piece 321, which can prevent air leakage between the lower glass piece 322 and the lower frame piece 321 due to machining or assembly errors, thereby ensuring the sealing property between the lower glass piece 322 and the lower frame piece 321.
[0054] Further, the third sealing ring 315 is arranged between the upper fixing member 313 and the upper glass member 312, and the fourth sealing ring 325 is arranged between the lower fixing member 323 and the lower glass member 322.

[0057] In combination Figure 4 And Figure 6 As shown in the drawings, the glass clamping assembly 30 further comprises a vacuum suction member 33, and the region between the upper glass clamping member 31 and the lower glass clamping member 32 is in communication with the vacuum suction member 33. Specifically, the vacuum suction member 33 can suck vacuum in a certain range of space. In the embodiment of the present application, when the material 200 needs to be exposed, the region between the upper glass clamping member 31 and the lower glass clamping member 32 is defined by the upper glass member 312, the upper fixing member 313, the upper frame member 311, the lower glass member 322, the lower fixing member 323, the lower frame member 321, the first sealing ring 314, the second sealing ring 324, the third sealing ring 315, the fourth sealing ring 325 and the fifth sealing ring 50, and the vacuum suction member 33 is in communication with the region between the upper glass clamping member 31 and the lower glass clamping member 32.
[0058] When the material to be exposed moves to the area between the upper glass clamping part 31 and the lower glass clamping part 32, the area can be vacuumed by the vacuum suction part 33, so that the material can be kept flat in the glass clamping assembly 30, thereby ensuring the quality of exposure.

The electric cylinder is in transmission connection with the tensioning assembly 20 and can drive the tensioning assembly 20 to move relative to the machine table 10.
[0060] In the embodiment of the utility model, two electric cylinders are arranged on the exposure device 100, and the two electric cylinders correspond to the two tensioning assemblies 20 one by one, so that the two electric cylinders can drive the corresponding tensioning assemblies 20 to move relative to the machine table 10.

[0062] Further, after the upper glass clamping part 31 rotates upward relative to the lower glass clamping part 32 under the action of the first driving assembly 40, the second driving assembly 60 can drive the material 200 to rise from the upper surface of the lower glass assembly, which can facilitate the two roll laying devices before and after the exposure device 100 to complete the material pulling action, and can facilitate the cleaning of the upper surface of the lower glass assembly, and facilitate wiping, so as to ensure the exposure quality in the subsequent sequence.
[0063] In combination Figure 5 As shown, the tensioning assembly 20 comprises a first roller shaft 21 and a second roller shaft 22 arranged at intervals, and the first roller shaft 21 is closer to the glass clamping assembly 30 in the first direction than the second roller shaft 22, and the first roller shaft 21 is located above the second roller shaft 22.

In this way, not only can the material 200 be laid on the exposure device 100, but also the material 200 can pass through the tensioning assembly 20 so that the material 200 can be lifted together with the tensioning assembly 20.
[0064] Under the action of the two front and back roll-off devices of the exposure device 100, the material 200 can be flattened and tensioned under the action of the first roller shaft 21 and the second roller shaft 22 to ensure the flatness of the material 200 in the exposure area.
[0065] Further, the top of the first roller shaft 21 is flush with the upper surface of the lower glass clamping piece 32, so that the material 200 extending from between the second roller shaft 22 and the first roller shaft 21 to the top of the first roller shaft 21 is flush with the material 200 arranged on the upper surface of the lower glass clamping piece 32, which is beneficial to improve the flatness of the material 200 in the exposure area and improve the exposure quality.

[0069] Further, the upper surface of the suction disc support 70 is flush with the upper surface of the lower glass clamping piece 32, so that the material 200 located on the upper surface of the suction disc support 70 is flush with the material 200 located on the lower glass clamping piece 32, which is beneficial to improve the flatness of the material 200 in the exposure area and improve the exposure quality.
[0070] In the embodiment of the utility model, when the material 200 needs to be exposed, the electric cylinder of the tensioning assembly 20 is in the retracted state. In the exposure area, the upper glass clamping piece 31 of the glass clamping assembly 30 is driven by the first driving assembly 40 to rotate downward relative to the lower glass clamping piece 32 to clamp the material 200 by the glass clamping assembly 30, and the suction vacuum piece 33 suctions vacuum in the area between the upper glass clamping piece 31 and the lower glass clamping piece 32 to ensure the flatness of the material 200.
[0071] In the non-exposure area, the suction disc support 70 performs a vacuum breaking process on the area between its upper surface and the material 200, so as to release the material 200, and then the tension assembly 20 is driven by the electric cylinder to lift the first roller shaft 21 and the second roller shaft 22, so as to lift the material 200, and then the material 200 is pulled by the unwinding and winding devices of the exposure device 100 and the exposure device 100 behind the exposure device 100, and waits for the exposure of the next frame of graphics.
[0072] Further, after the exposure of a frame of graphics is completed, in the exposure area, the suction vacuum 33 performs a vacuum breaking process on the area between the upper glass clamping member 31 and the lower glass clamping member 32, and at the same time, the upper glass member 312 rotates relative to the lower glass clamping member 32 under the driving of the first driving assembly 40, so as to open the glass clamping assembly 30 and release the material 200.
[0073] In the non-exposure area, the suction disc support 70 performs a vacuum breaking process on the area between its upper surface and the material 200, so as to release the material 200, and then the tension assembly 20 is driven by the electric cylinder to lift the first roller shaft 21 and the second roller shaft 22, so as to lift the material 200, and then the material 200 is pulled by the unwinding and winding devices of the exposure device 100 and the exposure device 100 behind the exposure device 100, and waits for the exposure of the next frame of graphics.
[0074] In the embodiments of the present application, the exposure device 100 can also facilitate the wiping and cleaning of the upper glass clamping member 31 and the lower glass clamping member 32, without the need to cut the material 200 or wait for the completion of the exposure of a roll of material 200, so that once dirt is found on the upper glass clamping member 31 or the lower glass clamping member 32 during the exposure process, the dirt can be found and cleaned in time, so as to ensure the exposure quality.
