[0033] Reference Figure 1 , 2 As shown in Figure 3, the excimer UV curing machine according to an embodiment of the present invention includes a frame 100, a conveyor belt 200, a sealing assembly, and a curing assembly 400. The frame 100 has a mounting cavity 110. The conveyor belt 200 is installed in the mounting cavity 110. The conveyor belt 200 includes an upper straight section 210, and gaps 211 exist between the left and right sides of the upper straight section 210 and the sidewalls of the mounting cavity 110. The sealing assembly includes sealing elements 300. Sealing elements 300 are installed on both the left and right sides of the frame 100. Both sealing elements 300 extend towards the center of the frame 100, and the sealing elements 300 can cover the gaps 211. Figure 3 As shown, the curing assembly 400 is installed on the top of the frame 100. The curing assembly 400 includes a cover 410 and a curing lamp 420 installed on the cover 410. The cover 410 and the conveyor belt 200 have a feed and discharge channel 430 extending in the front and rear direction. Both the feed end and the discharge end of the feed and discharge channel 430 are equipped with an air curtain 440 that can spray nitrogen downwards.

[0034] Two seals 300 respectively cover the gap 211 between the left and right sides of the upper straight section 210 and the side wall of the mounting cavity 110, preventing oxygen from entering the inlet / outlet channel 430 through the gap 211. In addition, air curtains 440 capable of spraying nitrogen are provided at the inlet and outlet ends of the inlet / outlet channel 430, thereby blocking external oxygen from entering the inlet / outlet channel 430 through the inlet and outlet ends. Through the above sealing and blocking, external oxygen is prevented from entering the inlet / outlet channel 430, thereby avoiding affecting the operation of the curing lamp 420.

[0035] During operation, the air curtains 440 at the feed end and discharge end are activated to block external oxygen from entering the feed-discharge channel 430 through the feed end and discharge end. The workpiece enters the feed-discharge channel 430 from the feed end and is placed on the upper straight section 210 of the conveyor belt 200. The conveyor belt 200 drives the workpiece to move backward. After the workpiece moves a certain distance, the conveyor belt 200 drives the workpiece to move out of the feed-discharge channel 430 from the discharge end. During the movement, the curing lamp 420 irradiates the workpiece.

[0036] Specifically, the lower end of the seal 300 can abut against the upper end of the upper straight section 210.

[0037] Specifically, a sealing cloth is also provided at the discharge end. The sealing cloth is located on the right side of the air curtain 440 at the discharge end, so that the sealing cloth can further block external oxygen from entering the inlet and outlet channel 430.

[0038] Specifically, the mounting cavity 110 is equipped with a drive roller and a driven roller spaced apart front and rear. The conveyor belt 200 is sleeved on the drive roller and the driven roller. The drive roller is connected to a motor, which drives the drive roller to rotate. The drive roller drives the conveyor belt 200 to move through the driven roller. The conveyor belt 200 drives the workpiece located on the upper straight section 210 to move backward.

[0039] Specifically, the conveyor belt 200 also includes a lower straight section and two circular arc sections, with the upper straight section 210 and the lower straight section located between the two circular arc sections.

[0040] Specifically, the curing lamp 420 is installed on the top of the cover 410, and the light from the curing lamp 420 can pass through the top of the cover 410 and illuminate the workpiece in the infeed / outfeed channel 430. Alternatively, the curing lamp 420 is installed on the cover 410 and located in the infeed / outfeed channel 430, so that the light from the curing lamp 420 directly illuminates the workpiece in the infeed / outfeed channel 430.

[0041] Specifically, the workpiece can be a sheet material or other workpieces that require UV curing.

[0042] In some embodiments of this utility model, such as Figure 2 , 4 As shown in Figure 5, the sealing assembly also includes a support member 500, the left and right sides of the support member 500 are fixedly connected to the left and right sides of the mounting cavity 110 respectively, and the upper straight section 210 is placed on the top of the support member 500.

[0043] By providing a support member 500, the upper straight section 210 is supported, enabling the upper straight section 210 to support heavier workpieces.

[0044] In a further embodiment of this utility model, such as Figure 5 , 6As shown, the conveyor belt 200 has annular positioning strips 220 extending in a ring shape along its inner sidewall on both the left and right sides. The support member 500 is provided with grooves 510 corresponding to the positions of the two annular positioning strips 220, and the two annular positioning strips 220 are respectively placed in the two grooves 510.

[0045] By providing a groove 510 on the support member 500, the annular positioning strip 220 inside the conveyor belt 200 can be embedded in the groove 510, thereby preventing the conveyor belt 200 from running off-center by matching the two annular positioning strips 220 with the two grooves 510.

[0046] In a further embodiment of this utility model, such as Figure 2 As shown, one end of the seal 300 is mounted on the support 500, and the other end of the seal 300 is placed on the upper straight section 210.

[0047] The seal 300 is installed in the manner described above, which facilitates the installation and removal of the seal 300, and a portion of the support 500 can serve as a sealing structure.

[0048] Specifically, the seal 300 can be a spacer made of Teflon material, which can remain in contact with the upper end of the upper straight section 210 under the action of the sprayed nitrogen gas.

[0049] In a further embodiment of this utility model, such as Figure 2 , 7 As shown in Figures 8 and 9, the device also includes a connector 600. The connector 600 includes a horizontal section 610 and a vertical section 620 located in the groove 510. One end of the horizontal section 610 is mounted on the support 500, and the other end of the horizontal section 610 is located above the groove 510 and connected to the upper end of the vertical section 620. An annular positioning strip 220 is placed between the groove 510 on one side near the middle of the frame 100 and the vertical section 620.

[0050] By providing a vertical section 620, the conveyor belt 200 can be prevented from running off-center, and the sides of the conveyor belt 200 can be sealed by the vertical section 620.

[0051] In a further embodiment of this utility model, such as Figure 9 As shown, one end of the seal 300 is mounted on the other end of the horizontal section 610.

[0052] Since the other end of the horizontal section 610 is located above the groove 510 and the seal 300 is fixed by screws, the groove 510 can conveniently accommodate the screws used to fix the seal 300, and one end of the seal 300 is fixed to the other end of the horizontal section 610, thus avoiding a wide distance between the left and right ends of the seal 300.

[0053] In some embodiments of this utility model, such as Figure 10 As shown, the cover 410 can be moved up and down and fitted onto the frame 100, thereby adjusting the height of the inlet and outlet channel 430 in the vertical direction, so that the excimer UV curing machine can be suitable for workpieces of different heights.

[0054] In a further embodiment of this utility model, such as Figure 10 As shown, a sealing strip 411 is installed between the inner sidewalls on the left and right sides of the cover 410 and the outer sidewall of the frame 100. The sealing strip 411 can seal the space between the inner sidewall and the outer sidewall.

[0055] By providing a sealing strip 411, gas leakage is prevented through the space between the inner and outer walls.

[0056] In a further embodiment of this utility model, such as Figure 10 As shown, there are multiple sealing strips 411, which are installed on the inner wall of the cover 410 at intervals along the vertical direction.

[0057] The sealing effect is improved by setting multiple sealing strips 411.

[0058] In a further embodiment of this utility model, such as Figure 10 As shown, the cover 410 is mounted on the frame 100 via the guide rail 412. The frame 100 is equipped with a drive device 413, which is connected to the cover 410 and can drive the cover 410 to move up and down.

[0059] During operation, the cover 410 is driven to move up and down along the guide rail 412 by the drive device 413.

[0060] The drive unit 413 can be a cylinder.
