The auxiliary lamp 10 is composed of a lampshade and a plurality of UV lamp tubes. The conveyor belt 3 of this structure can place the sensors that need to be plastic-sealed in a plurality of carrier frames 4 and transport them to the inside of the furnace body 2 in sequence, and start the UV lamp 5 to irradiate and bake the sensors in the carrier frames 4. When the carrier frames 4 are transported to the position between the mounting plates 6 of the same group, the cylinder 14 can drive the push block 8 to push horizontally on the movable plate 7. After the two push blocks 8 of the same group are closed together, the carrier frame 4 will be clamped, and then the movable plate 7 can be moved by The mounting plate 6 is lifted up to drive the loading frame 4 to rise to a certain height. At this time, the auxiliary light 10 can also achieve a certain degree of irradiation and baking effect on the bottom of the sensor through the bottom of the loading frame 4, so that the bottom of the sensor in the loading frame 4 can also be fully heated, avoiding the problem that the existing UV curing furnace can only place the product horizontally on the conveyor belt 3 for transportation, resulting in the bottom of the product being heated less than ideal, thereby making the sensor sealant in the furnace body 2 The overall curing effect is better, and the quality of the product is improved. Connecting rods 11 are welded and fixed at both ends of the inner side of the movable plate 7, and vertical openings 9 that match the connecting rods 11 are provided on both sides of the mounting plate 6, and the connecting rods 11 are movably penetrated inside the vertical openings 9, and the connecting rods 11 are connected to one end of the inner side of the mounting plate 6 There is a same push plate 12, and the connection between the push plate 12 and the connecting rod 11 is welded and fixed, and a hydraulic push rod 13 is fixedly installed on the upper end of the inner side of the mounting plate 6 through a support block, and the output end of the hydraulic push rod 13 is vertically downward and fixedly connected to the middle of the top of the push plate 12. When the hydraulic push rod 13 of this structure is driven, it will drive the push plate 12 to rise and fall on the inner side of the mounting plate 6.

The four corners of the auxiliary light 10 are fixedly connected to the four corners of the outer recessed part of the mounting plate 6 by screws, and the width of the auxiliary light 10 is the same as the depth of the recessed part on the outer side of the mounting plate 6. The auxiliary light 10 of this structure can be more closely installed in the recessed part on the outer side of the mounting plate 6 to ensure that the movable plate 7 can be smoothly raised and lowered on the outer side of the mounting plate 6.

[0019] Working principle: When using the UV curing furnace for sensor packaging, first place the sensors that need to be plastic-sealed in batches in the carrier frame 4, and then place the carrier frame 4 on the conveyor belt 3 at intervals. When the conveyor belt 3 drives at the top of the base 1 to transport the carrier frame 4 to the inside of the furnace body 2, start the UV lamp 5, and the UV lamp 5 will irradiate and bake the sensor surface in the carrier frame 4 until the carrier frame 4 is transported to the position between the mounting plates 6 of the same group, and then start the cylinder 14 on the mounting plate 6 of the same group. The cylinder 14 is driven on the movable plate 7 to drive the push block 8 to push horizontally until the two push blocks 8 are horizontally pushed into the slots on both sides of the carrier frame 4, so that the carrier frame 4 is clamped and fixed. At this time, start the same group again. The hydraulic push rod 13 on the mounting plate 6 will drive the push plate 12 to rise and fall on the inner side of the mounting plate 6 when the hydraulic push rod 13 is driven. When the push plate 12 rises and falls, it will drive the two connecting rods 11 to slide in the vertical opening 9, so as to synchronously drive the movable plate 7 to rise and fall on the outer side of the mounting plate 6. When the two movable plates 7 drive the loading frame 4 clamped between the push blocks 8 to rise to a certain height, the auxiliary light 10 can achieve a certain degree of irradiation and baking of the bottom of the sensor through the bottom plate of the loading frame 4 to improve the curing effect. After the bottom of the sensor is irradiated and baked for a certain period of time, the loading frame 4 is put back on the conveyor belt 3 for continued transportation in the above-mentioned reverse order, and the sensors in the next group of loading frames 4 are irradiated in this cycle, thereby completing a series of tasks.
