[0017] Furthermore, a plate body 100 with a top surface coated with paint is placed on the conveying roller body 11;

[0018] A plurality of ultraviolet curing lamps 1 are installed on the top plate of the conveying housing 10, and the ultraviolet curing lamps 1 perform light curing on the paint on the top surface of the plate body 100;

[0019] A plurality of lifting mechanisms 20 are also installed on the top plate of the conveying shell 10 , and a paint thickness measuring probe 30 is installed on the lifting mechanism 20 . The detection end of the paint thickness measuring probe 30 is close to the top surface of the plate body 100 .

[0020] Furthermore, a plurality of curing slots 12 extending forward and backward are formed on the top plate of the conveying housing 10, and a plurality of detection slots 15 extending forward and backward are formed on the top plate of the conveying housing 10. The curing slots 12 and the detection slots 15 are arranged at intervals, that is, a curing slot 12 is arranged between every two detection slots 15;

[0021] An upper cover 13 is fixed to the top surface of the top plate of the conveying housing 10, and the upper cover 13 covers the corresponding curing slots 12. A lower support frame 14 is fixed to the bottom surface of the top plate of the upper cover 13, and an ultraviolet curing lamp 1 is fixed to the bottom surface of the bottom plate of the lower support frame 14, and the ultraviolet curing lamp 1 is located in the corresponding curing slots 12. A plurality of detection slots 15 extending forward and backward are formed on the top plate of the conveying housing 10, and an upper connecting housing 17 is fixed to the top surface of the top plate of the conveying housing 10, and the upper connecting housing 17 covers the detection slots 15, and a lifting mechanism 20 is installed in the upper connecting housing 17.

[0022] Further, the lifting mechanism 20 includes a vertical plate 21 fixed to the front and rear of the bottom surface of the top plate of the upper connection shell 17, an upper transverse plate 22 fixed to the upper inner side walls of the two vertical plates 21, an upper portion of a vertical screw 23 movably connected to the upper transverse plate 22 through a bearing, a bottom portion of the vertical screw 23 movably connected to a connecting plate fixed to the lower inner side wall of the vertical plate 21 through a bearing, a lifting motor 24 is fixed to the front and rear of the top surface of the upper transverse plate 22, the output shaft of the lifting motor 24 is a spline shaft, which is inserted into the spline hole at the top of the corresponding vertical screw 23 and drives the corresponding vertical screw 23 to rotate, a lifting block 25 screwed on the two vertical screws 23 is fixed to the same lifting plate 26, and a paint surface thickness measuring probe 30 is fixed to the front and rear of the bottom surface of the lifting plate 26.

[0025] The paint thickness measuring probe 30 in this embodiment includes an outer shell, in which an LED infrared light source, a reflector and an infrared detector are installed. The principle is to use the modulated LED infrared light source pulse to heat the coating surface on the top surface of the plate body 100 by only 1° to 2° (without any damage or impact on the coating), and then the generated heat diffuses into the interior of the coating.

[0026] When reaching the interface between the coating and the substrate, the thermal radiation is reflected and thus detected by the infrared detector in the paint thickness measuring probe 30 .

[0027] This characteristic time depends on the heat dissipation efficiency of the coating. The thickness information of the coating can be obtained by detecting the infrared thermal radiation (phase shift) signal using an infrared detector.

[0028] The paint surface thickness measuring probe 30 is a product that can be directly purchased on the market and has a well-known structure, which will not be described in detail here.

[0029] When the present embodiment is in use, the plate 100 is transported from left to right along the driving roller 11 (due to the paint curing, the transport speed is relatively low, which is basically the same as the conventional drying equipment). The first one passes through the two paint thickness measuring probes 30 of the first lifting plate 26 for detection, and the thicker one is detected. At this time, the detection signal is transmitted to the control host, and the control host changes the irradiation frequency of the following ultraviolet curing lamp 1 to meet the curing needs of the surface of the plate 100. The plate 100 continues to be transported, and each time it passes through a paint thickness measuring probe 30, it needs to be detected once, so as to change the irradiation frequency of the following ultraviolet curing lamp 1, so as to ensure the curing needs of the paint surface of the plate 100 at all times;

[0030] Of course, during normal operation, some of the paint thickness measuring probes 30 can be turned off. The paint thickness measuring probe 30 of the first lifting mechanism 20, the paint thickness measuring probe 30 of the sixth lifting mechanism 20, and the paint thickness measuring probe 30 of the eleventh lifting mechanism 20 can be turned on, that is, every five lifting mechanisms 20 are turned on to reduce the frequent adjustment of the ultraviolet curing lamp 1.

[0031] The paint surface thickness measuring probe 30 can be adjusted by adjusting the height of the lifting plate 26, and the adjustment is convenient.
