[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-5 A UV curing device for a coating machine with an adjustable ultraviolet irradiation area includes a connecting frame, a connecting cover 2 is provided on the connecting frame 1, an isolation cover 3 is provided at the lower end of the connecting cover 2, and an adjustment component is provided in the connecting cover 2;

[0024] In this design, the connecting frame 1 is set on one side of the coater, the connecting cover 2 is set above the coater conveying device, and the isolation cover 3 is set below the conveying device. When the substrate needs to pass through the UV curing device, it passes through the UV curing device between the connecting cover 2 and the isolation cover 3.

[0025] The adjustment assembly includes a mounting plate 4 fixedly connected to the connecting frame 1, and a plurality of slide grooves 5 are provided on the lower surface of the mounting plate 4. A slider 6 is slidably connected in the slide groove 5, and a lampshade 7 is rotatably connected to the lower surface of the slider 6. An ultraviolet lamp 8 is provided in the lampshade 7, wherein the ultraviolet lamp 8 is a long ultraviolet lamp tube, a push plate 9 is slidably connected in the slide groove 5, and a pressure rod 10 is slidably connected on the slider 6, the upper end of the pressure rod 10 is against the push plate 9, and the lower end of the pressure rod 10 is against the lampshade 7, and an adjusting bolt 11 is provided on the upper surface of the mounting plate 4, and the lower end of the adjusting bolt 11 is against the push plate 9.

[0026] Based on the above design, in this adjustment component, multiple long ultraviolet lamp tubes serve as ultraviolet light sources. When the user adjusts the ultraviolet irradiation area as needed, the user can slide the lampshade 7 along the slide groove 5 according to actual needs, and one or more lampshades 7 slide to a state parallel to the slide groove 5. In addition, an appropriate number of ultraviolet lamps 8 are selected according to specific needs to form a lamp group with variable width. The maximum width of the lamp group is when the multiple lampshades 7 are rotated to a state perpendicular to the slide groove 5 and the multiple ultraviolet lamps 8 are spliced together. After the user completes the adjustment of the irradiation area, the user rotates the adjusting bolt 11 to drive the push plate 9 to move downward, and the push plate 9 drives the pressure rod 10 to move downward. At this time, the two ends of the pressure rod 10 respectively abut against the lampshade 7 and the push plate 9, thereby using friction to fix the multiple lampshades 7 in this state.

[0027] It should be noted that the duration of UV curing can be adjusted by adjusting the conveying equipment, and in the above design, the length of the entire ultraviolet irradiation area is fixed. Even if multiple lampshades 7 are rotated perpendicular to the slide 5, the total length of the multiple lampshades 7 after splicing is consistent with the length of the ultraviolet lamp tube. It is only necessary to adjust the speed of the conveying equipment according to the actual curing time requirements. In this design, the energy consumption of the equipment can be optimized without affecting the ultraviolet intensity. Adjustments to the ultraviolet irradiation area will not lead to the generation of more production variables, and are more convenient for users.

[0028] Furthermore, the connecting cover 2 includes a shell 21, the lower end of the shell 21 is fixedly connected to the isolation cover 3, and a light-blocking curtain 22 is provided on the lower surface of the shell 21 near the isolation cover 3, one of the light-blocking curtains 22 is provided with an adjustment rod 23, and the adjustment rod 23 is slidably connected to the shell 21, wherein the sliding connection between the adjustment rod 23 and the shell 21 is realized by a slide rail with a large friction coefficient, and the inner wall of the shell 21 is also slidably connected to a horizontal baffle 24;

[0029] In this design, a gap is provided at the lower end of the main body for making way for the conveying equipment, and a light-blocking curtain 22 is arranged in the gap. In fact, the light-blocking curtain 22 with an adjustment rod 23 is located at the front end of the conveying equipment. The user adjusts the position of the adjustment rod 23 according to the thickness of the substrate to avoid the light-blocking curtain 22 from contacting the substrate with uncured surface dye, and to avoid ultraviolet rays from being reflected to the outside of the shell 21 to the greatest extent. The baffle 24 is provided to make a more precise adjustment of the ultraviolet irradiation area. The horizontal sliding baffle 24 can adjust the irradiation range of the lamp group composed of multiple ultraviolet lamps 8, which is used in situations with more precise requirements.

[0030] Furthermore, a cross frame 12 is slidably connected to the connecting frame 1, and the cross frame 12 is fixedly connected to the mounting plate 4. One end of the cross frame 12 away from the mounting plate 4 passes through the housing 21.

[0031] In this design, a slidingly connected cross frame 12 is provided to slightly adjust the position of the irradiation area of the lamp group after the ultraviolet lamp 8 is activated, wherein the moving stroke of the cross frame 12 only needs half of the spacing of the slide groove 5 to meet the demand, and the cross frame 12 can also be provided with bolts and other fasteners for fixing it after adjusting the position of the cross frame 12.

[0032] Furthermore, the upper end of the pressure rod 10 is fixed with a compression spring 13, and the lower end of the pressure rod 10 is square, and the upper surface of the lampshade 7 is provided with a positioning groove matching the pressure rod 10;

[0033] In this design, the compression spring 13 can drive the pressure rod 10 to move upward and out of the positioning groove when the pressure plate is not pressed down, so that the lampshade 7 can rotate freely, which is convenient for the user to adjust. After the pressure plate is pressed down, the pressure rod 10 cooperates with the positioning groove to prevent the lampshade 7 from rotating, ensuring the fixing effect of the ultraviolet lamp 8.

[0034] Furthermore, a control rod 14 is fixedly connected to one side of the baffle 24. The control rod 14 is arranged through the housing 21, and a strip groove is opened on the housing 21 to make way for the adjustment rod 23.

[0035] This design makes it convenient for the user to adjust the position of the baffle 24 using the control lever 14 externally to meet the actual needs of the user.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
