Description

Technical Field

[0001] The invention relates to spray curing equipment, in particular to a control method of a UV curing energy online detection mechanism. Background Art

[0002] The applicant independently developed a method for curing UV skin-sub paint on the surface of a plate. The curing equipment includes a frame, an input conveyor belt structure, an intermediate conveyor roller structure, an output conveyor belt structure and an LED curing lamp. The advantages are: not only can the skin-feeling effect of the ultra-sub-light layer be achieved on a flat plate, but also the skin-feeling effect of UV skin-sub-light paint can be achieved on a plate with a special-shaped surface, which reduces consumption, simplifies the traditional coating process, and can achieve the skin-feeling effect of the ultra-sub-light layer produced by the excimer lamp curing technology. However, as the LED curing lamp is used for a long time, its energy will gradually decrease, thereby affecting the curing effect of the plate. Therefore, further improvement is needed. Summary of the invention

[0003] The purpose of the present invention is to provide a control method for a UV curing energy online detection mechanism which can effectively extend the service life of a UV energy lamp by detecting data of the UV energy lamp, so as to overcome the shortcomings of the prior art.

[0004] A control method for a UV curing energy online detection mechanism designed for this purpose includes a UV curing energy online detection mechanism, wherein the UV curing energy online detection mechanism includes a conveying device located below a UV energy lamp, the conveying device includes a conveying platform, an energy detection probe is provided on the conveying platform, a conductive lead connection structure is provided on one side of the conveying platform, the energy detection probe moves with the conveying platform and passes through the UV energy lamp, and the energy detection probe is in a powered state through the conductive lead connection structure to detect the energy value of the UV energy lamp.

[0005] The UV energy lamp is externally provided with an operation panel for setting a percentage setting value of the UV energy lamp utilization rate; it also includes a PLC controller for automatically compensating the light source energy value of the UV energy lamp according to the detection data of the energy detection probe, or controlling the light source brightness of the UV energy lamp according to the percentage setting value of the UV energy lamp utilization rate.

[0006] The UV energy lamp, the energy detection probe and the operation panel are respectively electrically connected to the PLC controller in a communication manner; the operation panel is a touch screen.

[0007] The conductive lead connection structure includes a support frame provided with a conductive strip, and a conductive spring located on the outside of the conveying device. The conductive spring is elastically retractable and electrically connected to the energy detection probe through a detection adapter. The conductive spring and the energy detection probe move with the conveying platform, and the conductive spring is in elastic contact with the conductive strip during the movement, which effectively solves the power supply and wiring problems of the energy detection probe.

[0008] The control method includes the following steps: a. manually inputting and setting a percentage setting value of the UV energy lamp utilization rate on the operation panel, and the PLC controller controls the light source brightness of the UV energy lamp according to the percentage setting value of the UV energy lamp utilization rate; b. the energy detection probe is in a powered-on state as the conveyor platform moves, and passes through the UV energy lamp above, thereby detecting the energy value of the UV energy lamp, and feeding back the detection information to the PLC controller; c. the PLC controller automatically compensates the light source energy value of the UV energy lamp according to the detection data of the energy detection probe.

[0009] The percentage setting value of the UV energy lamp utilization rate is set manually according to the curing process parameters of the workpiece. The percentage setting value of the UV energy lamp utilization rate is a part of the total energy of the UV energy lamp, and the other part of the total energy of the UV energy lamp is the light source energy compensation value.

[0010] If the light source of the UV energy lamp decays with long-term use, the PLC controller compensates the UV energy lamp through another part of the total energy of the UV energy lamp until the other part of the total energy of the UV energy lamp is compensated to a maximum value.

[0011] If the UV energy lamp is in automatic compensation, the light source detected by the energy detection probe cannot reach the set value of the UV energy lamp utilization percentage, and the information is fed back to the PLC controller, the PLC controller will generate an alarm.

[0012] Personnel replace the UV energy lamp according to the alarm signal sent by the PLC controller to avoid insufficient energy of the UV energy lamp, which will lead to poor curing effect of the workpiece.

[0013] The alarm processing is sound, indicator light, or display of alarm processing information on the touch screen.

[0014] The beneficial effects of the present invention are as follows:

[0015] By manually inputting and setting the percentage setting value of the UV energy lamp utilization rate, and setting the percentage setting value of the UV energy lamp utilization rate according to the curing process parameters of the workpiece, the UV energy lamp is used reasonably, and the rated service life of the UV energy lamp is fully utilized on the basis of ensuring the curing quality.

[0016] The PLC controller automatically compensates the energy value of the UV energy lamp according to the detection data of the energy detection probe, so as to avoid the problem that the energy of the UV energy lamp gradually decreases during long-term use, resulting in poor curing effect of the workpiece, and ensure that the energy used in the UV energy lamp during the curing process reaches the set value of the UV energy lamp utilization percentage.
