Technical Field
[0001] This utility model relates to the field of ultraviolet irradiation technology, and in particular to a device for linearly adjusting the power of an ultraviolet light source. Background Technology
[0002] With the continuous advancement of science and technology, ultraviolet (UV) irradiation has been widely applied in various fields such as medicine, agriculture, and materials science. However, the uniformity and precision of UV irradiation directly affect its effectiveness. By using a linear adjustment mechanism, the irradiation position of the UV light source can be adjusted in real time according to requirements.
[0003] Regarding the above and existing related technologies, the inventors believe that the following defects often exist: when the ultraviolet light source body cures a plastic product with a complex curved surface, if the position of the light source cannot be adjusted, the convex part of the curved surface near the light source will receive too much ultraviolet light, resulting in too fast curing, while the concave part of the curved surface may not be fully cured due to insufficient ultraviolet irradiation; therefore, in order to address the above problems, a device for linear adjustment of ultraviolet light source power is proposed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability to adjust the position of the light source, the excessive ultraviolet radiation received by the convex part of the curved surface near the light source leading to excessively rapid curing, and the insufficient ultraviolet radiation in the concave part of the curved surface resulting in inadequate curing. Therefore, this invention proposes a linear adjustment device for the power of an ultraviolet light source.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a linear adjustment device for ultraviolet light source power, comprising an L-shaped plate, a servo motor fixedly connected to the surface of the L-shaped plate, a threaded rod fixedly connected to the output end of the servo motor, a connecting block threadedly connected to the arc surface of the threaded rod, a U-shaped plate fixedly connected to the surface of the connecting block, and an ultraviolet light source body slidably connected to the surface of the U-shaped plate.
[0006] The effect achieved by the above components is to achieve linear adjustment of the position of the ultraviolet light source body, thus avoiding the situation where, when the ultraviolet light source body is curing a plastic product with a complex curved surface, if the position of the light source cannot be adjusted, the convex part of the curved surface near the light source will receive too much ultraviolet light, resulting in too fast curing, while the concave part of the curved surface may not be fully cured due to insufficient ultraviolet irradiation.
[0007] Preferably, both sides of the U-shaped plate are threaded with lead screws, and one end of the lead screw is fixedly connected to a handle.
[0008] The effect achieved by the above components is that rotating the handle drives the lead screw to rotate inside the U-shaped plate until the lead screw comes into contact with the surface of the ultraviolet light source body, so that the staff can disassemble and repair the ultraviolet light source body.
[0009] Preferably, a limiting groove is formed on the surface of the L-shaped plate, and the connecting block is slidably connected to the inner surface of the limiting groove of the L-shaped plate, and the size of the connecting block is adapted to the size of the limiting groove of the L-shaped plate.
[0010] The effect achieved by the above components is that the threaded rod drives the connecting block to slide on the inner surface of the L-shaped plate limiting groove, preventing the connecting block from rotating with the rotation of the threaded rod, thus improving the stability of the device.
[0011] Preferably, a U-shaped frame is fixedly connected to the surface of the ultraviolet light source body, a baffle is slidably connected to the inner surface of the U-shaped frame, short rods are fixedly connected to both sides of the U-shaped frame, an elliptical plate is fixedly connected to one end of the short rods, a limiting rod is slidably inserted into the elliptical plate, slots are opened on both sides of the baffle, and a mounting plate is fixedly connected to one end of the limiting rod.
[0012] The effect achieved by the above components is as follows: the baffle slides on the inner surface of the U-shaped frame, and the mounting plate drives the limiting rod to slide in the elliptical plate until the limiting rod is inserted into the baffle slot, thereby achieving the effect of blocking the lens of the ultraviolet light source body and preventing external dust from accumulating on the surface and affecting the ultraviolet irradiation.
[0013] Preferably, a spring is fixedly connected to the side of the mounting plate near the elliptical plate, and the other end of the spring is fixedly connected to the elliptical plate.
[0014] The effect achieved by the above components is that the spring itself drives the limiting rod to slide inside the elliptical plate and automatically insert into the baffle slot.
[0015] Preferably, a washer is fixedly connected to the end of the lead screw away from the handle, and the washer is made of rubber.
[0016] The effect achieved by the above components is that the rubber material has a certain elasticity, which can protect the surface of the ultraviolet light source.
[0017] Preferably, a setting block is fixedly connected to the surface of the baffle, and the size of the baffle is adapted to the size of the inner surface of the U-shaped frame.
[0018] The effect achieved by the above components is that pulling the setting block causes the baffle to slide on the inner surface of the U-shaped frame, so that the staff can pull the baffle stably and conveniently limit the position.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] 1. In this utility model, the position of the ultraviolet light source body is linearly adjusted, which avoids the situation where, when the ultraviolet light source body cures a plastic product with a complex curved surface, if the position of the light source cannot be adjusted, the convex part of the curved surface near the light source will receive too much ultraviolet light, resulting in too fast curing, while the concave part of the curved surface may not be fully cured due to insufficient ultraviolet irradiation.

[0027] Reference Figure 1-5As shown, this utility model provides a technical solution: a linear adjustment device for the power of an ultraviolet light source, comprising an L-shaped plate 1, a servo motor 2 fixedly connected to the surface of the L-shaped plate 1, a threaded rod 3 fixedly connected to the output end of the servo motor 2, a connecting block 4 threadedly connected to the arc surface of the threaded rod 3, a U-shaped plate 5 fixedly connected to the surface of the connecting block 4, and an ultraviolet light source body 9 slidably connected to the surface of the U-shaped plate 10. This achieves the effect of linearly adjusting the position of the ultraviolet light source body 9, avoiding the situation where, when the ultraviolet light source body 9 cures a plastic product with a complex curved surface, if the light source position cannot be adjusted, the convex part of the curved surface near the light source will receive too much ultraviolet light, resulting in excessively fast curing, while the concave part of the curved surface may not cure sufficiently due to insufficient ultraviolet irradiation. Both sides of the U-shaped plate 5 are threaded with lead rods 6, and one end of the lead rod 6 is fixedly connected to a handle 7. Rotating the handle 7 causes the lead screw 6 to rotate within the U-shaped plate 5 until it abuts against the surface of the ultraviolet light source body 9, facilitating disassembly and maintenance of the ultraviolet light source body 9. A limiting groove is formed on the surface of the L-shaped plate 1, and the connecting block 4 is slidably connected to the inner surface of the limiting groove of the L-shaped plate 1. The size of the connecting block 4 matches the size of the limiting groove of the L-shaped plate 1. The threaded rod 3 drives the connecting block 4 to slide on the inner surface of the limiting groove of the L-shaped plate 1, preventing the connecting block 4 from rotating with the threaded rod 3, thus improving the stability of the device. A U-shaped frame 10 is fixedly connected to the surface of the ultraviolet light source body 9, and a baffle 11 is slidably connected to the inner surface of the U-shaped frame 10. Short rods 12 are fixedly connected to both sides of the U-shaped frame 10, and an elliptical plate 13 is fixedly connected to one end of each short rod 12. A limiting rod 14 is slidably inserted into the elliptical plate 13. Slots are formed on both sides of the baffle 11, and a mounting plate 15 is fixedly connected to one end of the limiting rod 14. Pulling the baffle 11 along the inner surface of the U-shaped frame 10 slides the mounting plate 15, causing the limiting rod 14 to slide within the elliptical plate 13 until the limiting rod 14 is inserted into the slot of the baffle 11. This achieves the effect of shielding the lens of the ultraviolet light source body 9, preventing external dust from accumulating on the surface and affecting ultraviolet irradiation. A spring 16 is fixedly connected to the side of the mounting plate 15 closest to the elliptical plate 13, and the other end of the spring 16 is fixedly connected to the elliptical plate 13. The spring 16's own elasticity drives the limiting rod 14 to slide within the elliptical plate 13 and automatically insert into the slot of the baffle 11. A washer 8, made of rubber, is fixedly connected to the end of the lead screw 6 away from the handle 7. The rubber material has a certain elasticity and can protect the surface of the ultraviolet light source body 9. A setting block 17 is fixedly connected to the surface of the baffle 11, and the size of the baffle 11 is adapted to the size of the inner surface of the U-shaped frame 10. Pulling the setting block 17 causes the baffle 11 to slide on the inner surface of the U-shaped frame 10, so that the staff can pull the baffle 11 stably and conveniently limit the position.
[0028] Working principle: When the operator needs to perform linear adjustment on the ultraviolet light source body 9, the servo motor 2 is activated. The servo motor 2 drives the threaded rod 3 to rotate, the threaded rod 3 drives the connecting block 4 to move, the connecting block 4 drives the U-shaped plate 5 to move, and the U-shaped plate 5 drives the ultraviolet light source body 9 to move. When the ultraviolet light source body 9 needs to be disassembled for maintenance, the handle 7 is turned to drive the lead screw 6 to rotate within the U-shaped plate 5. The lead screw 6 drives the shim 8 to move until the shim 8 no longer contacts the ultraviolet light source body 9. When it is necessary to shield the lens of the ultraviolet light source body 9... Pulling the mounting plate 15 causes the limiting rod 14 to slide within the elliptical plate 13 until the limiting rod 14 disengages from the slot of the baffle 11. At this point, the baffle 11 slides within the U-shaped frame 10, blocking the ultraviolet light source body 9. This achieves the effect of linearly adjusting the position of the ultraviolet light source body 9, preventing the ultraviolet light source body 9 from receiving too much ultraviolet light when curing a plastic product with a complex curved surface if the position of the light source cannot be adjusted. This would cause the convex part of the curved surface near the light source to receive too much ultraviolet light, resulting in too fast curing, while the concave part of the curved surface may not be fully cured due to insufficient ultraviolet irradiation.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
