DETAILED DESCRIPTION
[0018] To facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below in conjunction with specific embodiments and drawings.
[0019] Reference Figure 1 to Figure 2 The present invention provides a wood painting method, comprising the following steps: Step 1, providing a paint management system, the paint management system includes a central control module, a communication module, an information collection module, a data storage module, a scheduling module and a control terminal, the central control module is used to comprehensively control the production process, the communication module is used for data transmission between various modules, the information collection module is used to collect production information of the production workshop, the scheduling module is used to schedule materials and equipment in production, and the control terminal can be a computer, mobile phone, tablet computer and other devices, which is convenient for the staff to perform operations such as parameter adjustment; Step 2: The central control module obtains the production task, extracts the design data of the product to be produced from the data storage module according to the production task, and grabs each part of the product. That is, each product is composed of several parts. The central control module lists each part separately. The extracted products can be multiple, that is, parts of different products can be sprayed at the same time; Step 3: Group product parts according to production allocation rules, group identical parts or parts with similar dimensions into one group, and generate corresponding group numbers; Step 4: The central control module classifies and sorts each part group according to the processing task and generates a preliminary processing plan; Step 5: The scheduling module matches the part group to the painting equipment according to the processing plan. Each part group corresponds to one painting equipment. During the matching process, the wood parts in the part group are matched to different types of painting equipment according to their size or painting process. For example, large-sized wood parts are matched to large-sized painting equipment. Step 6: Transport the parts group to the corresponding painting equipment to spray paint on the surface of the wood parts. The parts transportation process can be carried out by AVG trolley to realize automatic transportation; Step seven: inspect the painted wood parts.
[0020] The elements of the production allocation rules in step three include at least product type and quantity, product process type, number of existing parts, etc. Take product process type as an example. For example, in a specific design, some products need to be sprayed with water-based paint, and some products need to be sprayed with oil-based paint. In the grouping process, the same process needs to be allocated to the same group. Among the wood parts of the same process type, the same parts or parts with similar external dimensions are further divided into one group. Then, different groups of wood parts are matched to different painting equipment respectively.
[0021] The detection of the painted wood parts adopts an image sensor, which acquires an image of the wood part, compares it with the standard part image, and determines whether the appearance of the wood part meets the design requirements. At the same time, the acquired image is processed and the color is extracted, and the extracted color is compared with the standard color in the pre-stored color library to determine whether the paint color is consistent with the design color. When it is detected that the appearance of the wood part does not meet the design requirements or the color does not meet the design requirements, the wood part is taken out, and the paint layer is subsequently ground off and then repainted.
[0022] The information acquisition module includes several cameras, which are installed in the paint spraying equipment and various locations in the production workshop. The cameras collect the images of the paint spraying equipment and the workshop images, and send the images to the central control module. The central control module judges the current paint spraying process status based on the image data and allocates the parts group in real time according to the paint spraying process status. In addition, the information acquisition module also includes an air quality detector, a temperature sensor, a humidity sensor, etc., which can monitor the environmental status of the production workshop in real time. After the camera collects the workshop image, it can perform feature analysis on the image and allocate operators according to the operation status of different workstations.
[0023] The spray painting of the wood part surface comprises: A1, spray primer on the surface of wood parts, spray primer three times, each spray thickness is 8-14μm; A2, sand and repair the surface of wood parts after spraying primer to make the paint surface thickness uniform; A3, spray paint on wood parts. When spraying paint, you can also refer to the primer spraying process and spray multiple times; A4, spray the topcoat on the wood parts. When spraying the topcoat, you can also refer to the primer spraying process and spray multiple times; A5, let the wood parts dry; A6, polish the topcoat.
[0024] Before the wood parts are sprayed with paint in step 6, pre-treatment is required, and the pre-treatment includes: S1, inspect the wood parts and screen out defective ones. If the wood parts only have minor surface cracks that do not affect the performance, they can be repaired with wood repair agents; S2, grinding the surface of wood parts to remove burrs; S3, use high-pressure airflow to blow the surface of the wood parts to clean the surface of the wood parts. If there is grease on the surface of the wood, degreasing operation is required; S4, controlling the moisture content of the wood parts to be between 8% and 15%. In this embodiment, the moisture content of the wood parts is controlled to be 12%.
[0025] The paint spraying equipment includes a chassis, a frame arranged in the chassis, a plurality of conveying rollers arranged on the frame, a paint spraying tank arranged between adjacent conveying rollers, and a paint spraying mechanism arranged on the frame, the paint spraying mechanism includes a column arranged on the frame, a cross bar connected to the column, a plurality of fixed rods connected to the cross bar, and a spray head connected to the fixed rod, the number of the fixed rods, the number of the spray heads, and the number of the paint spraying tanks correspond, and the spray head is located in the paint spraying tank.
[0026] Both side walls of the paint spraying tank are provided with openings, and the upper end portions of the side walls of the paint spraying tank are tilted outward to form a funnel shape, so that the upper ends of the side walls of two adjacent paint spraying tanks are in contact with each other. In addition, two opposite side walls of the chassis also have openings, and the wood parts enter the paint spraying equipment from the opening on one side, pass through each paint spraying tank in turn under the conveying of the conveying roller, and finally flow out from the opening on the other side.
[0027] A paint box is arranged below the paint spraying tank, and a sloping plate is connected to the bottom of the paint spraying tank, and the sloping plate extends to the paint box. During the painting process, the paint that is not sprayed onto the surface of the wood part can flow from the inner wall to the sloping plate under the action of gravity, and then enter the paint box at the bottom along the sloping plate.
[0028] The connection angles of several fixing rods relative to the cross bar are different. Specifically, during the installation and fixing process, the fixing rods rotate with the cross bar as the center of the circle, and are locked after rotating to a suitable angle. Different fixing rods are adjusted to different angles so that the spray head can be directed to different positions, thereby ensuring that the paint can evenly cover the surface of the wood parts during the painting process. In actual operation, a different painting equipment from this embodiment can also be used according to actual needs.
[0029] The present invention uses a paint spraying management system to grab each part of a product, and according to the production allocation rules, the same parts or parts with similar dimensions are divided into a group, and the part group is matched to a suitable paint spraying equipment for paint spraying during the painting process, without the need to frequently adjust the paint spraying equipment, thereby reducing manual intervention, improving the efficiency of the paint spraying operation, reducing labor intensity, and saving production costs. On the other hand, the paint spraying management system can grab parts of different products at the same time, so that the same parts or parts with similar dimensions in different products can be painted, further improving the operating efficiency and adapting to mass production.
