Work piece UV undercoat coating device and coating technology

Abstract

The utility model relates to the technical field of work piece UV undercoat coating, in particular to a work piece UV undercoat coating device and a coating process of the work piece UV undercoat coating device. An automatic transport line penetrates through cooling regions, dust-free spraying rooms and leveling segment preheating regions and connects the cooling regions, the dust-free spraying rooms and the leveling segment preheating regions. The cooling regions are connected with the dust-free spraying rooms. The dust-free spraying rooms are connected with the leveling segment preheating regions. At least two sets of devices are formed by connecting and combining the cooling regions, the dust-free spraying rooms and the leveling segment preheating regions. The cooling regions, the dust-free spraying rooms and the leveling segment preheating regions are of a sealed structure, energy consumption is saved, the problem that the defective rate of products caused by collision, dust falling and the like in the secondary transport process is increased is avoided, the whole coating device is of the sealed structure, gas generated in the coating process is discharged outwards after being processed through a wind pumping system, and it is avoided that poisonous and harmful gas is harmful to the human body heath of operators. When the work piece UV undercoat coating device is adopted to conduct coating, production efficiency is improved, the percent of pass of products can reach 95%, and finally the product quality is improved obviously as well.

Description

technical field [0001] The invention relates to the technical field of workpiece UV primer coating, in particular to a workpiece UV primer coating device and a coating process thereof. Background technique [0002] The existing UV production line on the market uses an independent spray booth for the primer color, and then manually moves it onto the frame, then transfers it to a bread-type oven for forced baking for 30-40 minutes, and then removes the frame from the bread-type oven. The workpiece is moved out of the oven, and then put the workpiece into the UV curing area for UV curing molding. During the secondary transfer process, it is easy to cause secondary defect rates such as dust, bumps, and abrasions to increase, and the production efficiency is very low. [0003] The existing UV primer coating line still has the problem of low coating qualification rate of products. Using traditional coating technology, the utilization rate of raw materials is not high, which is eas...

Problems solved by technology

[0002] The existing UV production line on the market uses an independent spray booth for the primer color, and then manually moves it onto the frame, then transfers it to a bread-type oven for forced baking for 30-40 minutes, and then removes the frame from the bread-type oven. Move it out of the oven, and then put the workpiece into the UV curing area for UV curing molding. During the secondary transfer process, it is easy to cause secondary defect rates such as dust, bruises, and abrasions to rise, and the production efficiency is very low.

[0003] The existing UV primer coating line still has the problem of low coating qualification rate of products. Using traditional coating technology, the utilization rate of raw materials is not high, which is easy to cause waste of coating raw materials. It is necessary to manually transfer the workpiece, which increases the labor cost, and the primer contains harmful chemical substances, which will affect the operator's body

[0004] see figure 1 The schematic diagram of the traditional process route, the workpiece is first sprayed with primer on the spraying station 22, and the workpiece at the spraying station 22 is manually transferred to the vehicle frame 23, and then the vehicle frame 23 is manually transferred to the bread oven 24. The front door of the oven 24 enters, the temperature of the bread oven 24 is controlled at 60-70 ° C, baked in the bread oven 24 for 30-40 minutes, and then manually transferred from the back door of the bread oven 24 to the UV curing area 1. Carry out UV curing. After the UV curing is completed, it is manually transferred to the lower workpiece area 25. After the traditional UV production line uses the primer color with an independent spraying station 22 for construction, it is first manually carried on the vehicle frame 23, and then transferred into The bread-type oven 24 is forced to bake for 30-40 minutes, then the vehicle frame 23 is removed from the bread-type oven 24, and then the workpiece is put into the UV curing area 1 for UV curing and molding. During the secondary transfer process, it is easy to cause Dust, bruises, scratches and other secondary defect rates increase, and the production efficiency is very low
