[0020] 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.

[0021] Reference Figure 1-5 A UV curing device for printed circuit boards includes a conveying unit 1, a shell 11 is provided above the conveying unit 1, a lamp board 12 is slidably connected to the shell 11, the lamp board 12 is fixed to the shell 11 by a locking assembly 2, and a plurality of lamp strips 13 are connected to the lamp board 12. Lifting assemblies 4 are fixedly connected to both sides of the conveying unit 1, and the lifting assemblies 4 are used to drive the shell 11 to move up and down. A pop-up assembly 5 for popping out the lamp board 12 is provided inside the shell 11, wherein the lamp strip 13 and the lamp board are connected by screws, and a universal wheel is provided at the lower end of the conveying unit 1 to facilitate the change of the position of the device, wherein the lamp strip 13 is connected to the power supply through a wire.

[0022] In this embodiment, the lifting assembly 4 includes a shell 41 fixedly connected to the brackets on both sides of the conveying unit 1, and a motor 42 is fixedly connected to the outside of the shell 41. The shaft end of the motor 42 is passed through the shell 41, and the shaft end of the motor 42 is fixedly connected to a worm 46. A gear 43 is rotatably connected in the shell 41. A rack 44 is also passed through the shell 41, and the upper end of the rack 44 is fixedly connected to the outer shell 11. The rack 44 meshes with the gear 43. A worm gear 45 is fixedly connected to one side of the gear 43, and the worm gear 45 meshes with the worm 46. When the motor 42 rotates, it drives the worm 46 to rotate, and the meshing of the worm 46 drives the worm wheel 45 to rotate. The worm wheel 45 is fixedly connected to the gear 43, so when the worm wheel 45 rotates, the gear 43 also rotates. The gear 43 rotates and meshes with the rack 44, driving the rack 44 to move up and down.

[0023] It should be noted that the locking assembly 2 includes a block 21 slidably connected to the groove of the lamp board 12 , a spring 22 is fixedly connected between the block 21 and the lamp board 12 , and a hole adapted to the block 21 is opened on the housing 11 .

[0024] Furthermore, the pop-up assembly 5 includes a telescopic rod 51 fixedly connected to the inner side of the shell 11, and the other end of the telescopic rod 51 is fixedly connected to a contact plate 52. A compression spring 53 is sleeved on the telescopic rod 51, and the contact plate 52 contacts the light board 12. When the light strip 13 needs to be replaced, the block 21 is pressed to shrink it into the groove where the spring is located in the shell 11. At this time, the restriction on the light board 12 is cancelled, the compression spring 53 has tension, and the telescopic rod 51 stretches, so that the contact plate 52 slides forward and pushes the light board 12 out.

[0025] Among them, baffles 15 are fixedly connected to the brackets on both sides of the conveying unit 1, and the baffles 15 are slidably connected to the shell 11. Under normal circumstances, the baffles 15 are useless when stored in the shell 11, but when the rack 44 lifts the shell 11 and moves upward, a gap appears at the lower end. At this time, the baffle 15 can block the gap to prevent light from leaking out.

[0026] On the basis of the above embodiment, plates 14 are fixedly connected on both sides of the interior of the shell 11. The plates 14 are used to support the lamp board 12. In order to prevent the lamp board 12 from tilting in the shell 11, the plates 14 are used to support the work and assist the lamp board 12 to slide in the shell 11.

[0027] Working method: When working, the lamp board 12 is inserted into the shell 11 and is engaged with the hole on the shell 11 through the block 21 to prevent it from falling off. According to the size and height of the circuit board, the motor 42 is turned on. When the motor 42 rotates, it drives the worm 46 to rotate, and the worm 46 engages to drive the worm gear 45 to rotate. The worm gear 45 is fixedly connected to the gear 43, so when the worm gear 45 rotates, the gear 43 also rotates. The gear 43 rotates and engages with the rack 44, driving the rack 44 to move up and down. The rack 44 moves up and down and drives the shell 11 up and down at the same time, so as to adjust the illumination height. When the light strip 13 or the lamp board 12 needs to be cleaned and replaced, just press the block 21 to retract it into the groove where the spring is located in the shell 11. At this time, the restriction on the lamp board 12 is cancelled, the compression spring 53 has tension, and the telescopic rod 51 stretches, thereby resisting the board 52 to slide forward and pushing the lamp board 12 out. The lamp board 12 can be easily taken out for replacement and cleaning.

[0028] 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.
