Description

Technical Field

[0001] The present invention relates to the technical field of surface coating of plate-type parts, and in particular to a coating process for whole-plate production parts, that is, a process for arranging more than one parts on a whole plate and coating the surface at the same time. Background Art

[0002] Wooden furniture parts are usually in the form of board parts. The existing surface coating process for wooden furniture parts is to carry out surface coating on a single piece basis after the wooden furniture parts are processed and formed, that is, paint is applied after the woodworking is completed, usually after several coats of primer and topcoat. If the manual coating process is adopted, there are shortcomings such as high labor intensity, low production efficiency, and difficult quality control. However, in order to achieve a certain paint film thickness, especially to achieve a high-gloss mirror effect, the use of a robot automatic spraying method often requires several or even more than ten times of repeated spraying, which has the shortcomings of large material loss and paint mist pollution of the environment. Especially for personalized customized furniture parts with multiple sizes, multiple specifications, and multiple processes, the existing method of coating greatly increases the difficulty of mass and large-scale production. Summary of the invention

[0003] In view of the shortcomings of the existing wooden furniture parts painting process, such as high labor intensity, low production efficiency, difficult quality control, large material loss and environmental pollution, the purpose of the present invention is to provide a whole-board production parts painting process which saves manpower, is easy to operate, has high production efficiency, easy quality control, low material loss, low coating cost and no environmental pollution.

[0004] The technical solution adopted for the purpose of the present invention is achieved in the following way: a whole plate production component painting process, the key points of which are: one or more non-intersecting component patterns are set on a whole plate, contour grooves are processed on the contour lines of each component pattern, and then the contour grooves of the components are filled with edge-sealing paint. After the contour grooves of each component on the same whole plate are filled with edge-sealing paint, the surface of the plate is painted.

[0005] Furthermore, the whole board is made of artificial board or wooden board.

[0006] Furthermore, the contour groove of the component is obtained by machining with a numerically controlled machine tool.

[0007] Furthermore, filling the contour groove of the component with the edge-sealing coating is achieved by injection molding using a CNC machine tool.

[0008] Furthermore, each of the components is provided with a chip.

[0009] Furthermore, the chip is a storage chip, which can store various information of related parts, such as name, model, shape, size, purpose, etc.

[0010] Furthermore, the chip is arranged in a chip positioning pit of each component.

[0011] Furthermore, the chip positioning pit is obtained by machining with a numerically controlled machine tool.

[0012] Furthermore, the chip is fixed in the chip positioning pit by filling a sealing coating into the chip positioning pit.

[0013] Furthermore, filling the chip positioning pit with the sealing coating is achieved by injection spraying using a CNC machine tool.

[0014] Furthermore, after each of the chip positioning pits on the same whole plate is filled with the sealing paint, the surface of the plate including the chip positioning pits is painted.

[0015] Furthermore, after the surface of the plate containing the component pattern is painted, the surface of the plate is further processed by a whole-plate mold-pressing coating process so that the surface of the plate achieves a high-gloss mirror or matte skin-feel effect.

[0016] Furthermore, after the coating process is completed on the surface of the plate containing the component patterns, the various components assembled on the same plate are separated one by one by a CNC machine tool.

[0017] A coating process for whole-plate production parts, which is completed by a CNC machine tool, includes the following steps: ⑴ Place a plate on the workbench of the CNC machine tool, with the front side of the plate facing down and the back side of the plate facing up; (2) Inputting the processing data of the component drawing into the computer of the CNC machine tool, wherein the processing data of the component drawing includes the geometric shape and geometric dimensions of the component drawing, the chip positioning position, and the geometric dimensions of the chip positioning pit; (3) Calculating the processing data of the component pattern to obtain block data corresponding to the processing data; (4) Arranging the drawings of the parts to be processed on a whole plate 1 according to the obtained block data, wherein the drawings of the parts do not intersect with each other; (5) According to the obtained block data, the component contour groove is processed along the part contour line of each component drawing according to the geometric shape and geometric size of each component drawing on the back of the plate, and the chip positioning pit is processed according to the chip positioning position and the geometric size of the chip positioning pit; (6) fixing the chip in the chip positioning pit according to the obtained block data; ⑺ Filling the coating into the contour grooves of each component and the chip positioning pits where each chip is provided according to the obtained block data; ⑻ Turn over the plate placed on the workbench of the CNC machine tool, with the front side of the plate facing up and the back side of the plate facing down; (9) According to the obtained block data, execute processing to form component contour grooves along the component contour lines of the component drawings according to the geometric shapes and geometric dimensions of the component drawings on the front side of the plate; ⑽ Filling the coating into the contour grooves of each component according to the obtained block data; ⑾ Paint the front side of the plate according to the obtained block data; ⑿ Turn over the plate placed on the workbench of the CNC machine tool, with the back of the plate facing up and the front of the plate facing down; ⒀ Paint the back of the plate according to the obtained block data; ⒁ According to the obtained block data, the various components assembled on the same plate are separated one by one.

[0018] Compared with the existing wooden furniture parts coating process, the whole-board production parts coating process provided by the present invention has the characteristics of simple operation, high production efficiency, easy quality control, low material loss, low coating cost and no environmental pollution. In particular, the whole-board production parts coating process can be combined with chip recognition technology and whole-board molding coating process, so that parts of multiple sizes and specifications can be controlled by information technology in the entire production process, various errors can be prevented, and the automation of the parts coating process can be realized.
