Description

Technical Field

[0001] This utility model relates to the field of workpiece coating technology, and in particular to a workpiece coating production line. Background Technology

[0002] Workpiece coating production lines are widely used in many industrial fields such as automobile manufacturing, machinery processing, home appliance production, furniture manufacturing, and shipbuilding. In automobile manufacturing, they are used for coating the body and parts. The workpieces first enter the pretreatment equipment and go through degreasing, pickling, phosphating, and water washing processes in sequence to remove surface oil, rust, oxide scale and other impurities, forming a phosphating film that is conducive to coating adhesion, and preparing for subsequent coating. Currently, the purpose of the pretreatment cleaning stage before workpiece coating is to remove impurities such as oil, dust, rust, and scale from the workpiece surface, so as to provide a good foundation for the subsequent coating process. However, the water used for cleaning by the existing cleaning method is difficult to use and recycle in a reasonable way, resulting in a waste of resources. Chinese patent publication number CN215088368U discloses a workpiece coating production line, belonging to the field of coating automation technology. It includes: a workpiece conveying system arranged in a closed loop for transporting workpieces; a spraying module, a preheating module, a powder coating module, and a baking module arranged sequentially along the conveying direction of the workpiece conveying system; the spraying module includes multiple spraying units arranged linearly along the conveying direction, which sequentially perform degreasing, rust removal, cleaning, and phosphating treatments on the workpieces; the preheating module is located adjacent to the burner for preheating the workpieces; the powder coating module is a sealed box, where powder is sprayed onto the workpieces and excess powder is recovered; the baking module includes a first baking oven, which has multiple interconnected baking chambers to extend the baking time of the workpieces and ensure uniform curing of the powder on the workpiece surface. This invention improves the automation level of the spraying system and increases production efficiency. While this patent improves production efficiency, it makes it difficult to thoroughly clean the workpieces. Utility Model Content

They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0024] Example 1: Please refer to Figure 1 - Figure 6 A workpiece coating production line includes a frame 1, and further includes: a housing 2 fixed on the frame 1, a water storage tank 3 fixed on the housing 2, a cleaning mechanism 4 provided on the housing 2 for cleaning the workpiece; and a water storage box 5 fixed on the housing 2, a recycling mechanism 6 provided on the water storage box 5 for filtering and collecting the cleaning water. The central axis of the housing 2 and the central axis of the water storage box 5 are located on the same axis. Several anti-slip pads are fixed at the bottom of the frame 1. It should be noted that the housing 2 is convex in shape, which facilitates the installation of a production line on the top of the housing 2, thereby ensuring that the workpiece can be smoothly transferred and moved inside the housing 2. The cleaning mechanism 4 sprays and cleans the workpiece to ensure that the workpiece surface remains clean, which is convenient for coating processing.

[0025] Furthermore, the cleaning mechanism 4 includes: a water inlet pipe 7 connected to the interior is fixed on the water storage tank 3; a water pump 9 is fixed on the water storage tank 3 via a bracket 8; a water pipe a10 is fixed between the input end of the water pump 9 and the water storage tank 3; several equally spaced spray pipes 11 are fixed inside the frame 1; a connecting pipe 12 is fixed at one end of several spray pipes 11; a water pipe b13 is fixed between the output end of the water pump 9 and one of the connecting pipes 12; a connecting pipe 14 is fixed between the two connecting pipes 12; a transparent plate 24 is fixed on the water storage tank 3; the transparent plate 24 is connected to the interior of the water storage tank 3; the addition of the transparent plate 24 makes it easier for staff to directly and intuitively judge the water storage volume inside the water storage tank 3 from the outside; a support frame 25 is fixed at the bottom of the water storage tank 3; the bottom surface of the support frame 25 is set at the same horizontal plane as the bottom surface of the shell 2. Among them, a rotating shaft 15 is rotatably connected to the water storage tank 3, and several circumferentially distributed stirring rods 16 are fixed on the rotating shaft 15. A servo motor 17 is fixed on the water storage tank 3, and the output shaft of the servo motor 17 is coaxially fixed with one end of the rotating shaft 15. The central axis of the rotating shaft 15 is collinear with the central axis of the water storage tank 3. The water inlet pipe 7 is located on one side of the servo motor 17. It should be noted that the cleaning mechanism 4 can effectively allocate and utilize water resources. Pressurized clean water is evenly sprayed onto the surface of the workpiece to be cleaned through the spray pipe 11, ensuring that the workpiece surface can reach an ideal clean state. Such a cleaning process is crucial to prevent dust and other contaminants from adhering to the workpiece surface. If impurities are not removed, they will seriously affect the quality of subsequent coating processing. The cleaning method of this device can significantly improve the coating effect of the workpiece during the coating process and ensure that the quality of the final product meets the standards. It should also be noted that for workpieces requiring special cleaning, treatment agents and a fixed amount of water can be added to the water storage tank 3 through the water inlet pipe 7. The stirring rod 16 driven by the servo motor 17 will stir and mix the contents of the water storage tank 3, thereby ensuring that the treatment agents can be fully and evenly mixed with the water, thus improving the cleaning efficiency of the workpieces.

[0026] In this plan, the workpiece cleaning process is as follows: First, driven by the water pump 9, the water source in the water storage tank 3 is extracted and pressurized by the water pipe a10. The pressurized water is then input into the connecting pipe 12 through the water pipe b13. The water source is distributed to the two connecting pipes 12 by the connecting pipe 14. The water source is then sprayed evenly onto the workpiece by the spray pipe 11. Secondly, the water source after cleaning seeps into the water storage box 5, where the water source is filtered by the filter plate 18, and the filtered water source enters the water storage box 5. Then, driven by the drive motor 22, the bidirectional threaded rod 19 rotates synchronously. Utilizing the threaded transmission between the bidirectional threaded rod 19 and the threaded sleeve 20, the threaded sleeve 20 moves along the inside of the water blocking plate 26, thereby driving the brush plate 21 to move synchronously. The brush plate 21 rubs against the filter plate 18, thus completing the cleaning work of the filter plate 18.

[0027] Example 2: Based on Example 1, according to Figure 4 - Figure 6 As shown, it is worth noting that the recycling mechanism 6 includes: a filter plate 18 fixed on the water storage box 5; a bidirectional threaded rod 19 rotatably connected to the water storage box 5; a threaded sleeve 20 threadedly connected to the bidirectional threaded rod 19; a brush plate 21 fixed on the threaded sleeve 20; the brush plate 21 abutting against the filter plate 18; the brush plate 21 slidingly connected to the inner side of the water storage box 5; a drive motor 22 fixed on the water storage box 5; one end of the output shaft of the drive motor 22 coaxially fixed with one end of the bidirectional threaded rod 19; a water blocking plate 26 fixed on the water storage box 5; and the threaded sleeve 20 slidingly connected inside the water blocking plate 26. The vertical cross-section of the water blocking plate 26 is concave. By adding the water blocking plate 26, it can not only guide the threaded sleeve 20, but also further reduce the contact between the water source and the bidirectional threaded rod 19. The top side of the water storage box 5 is beveled, and the bottom of the water storage box 5 is fixed with a water outlet pipe 23 that is connected to the inside. The beveled top surface of the water storage box 5 ensures that the water source can enter the water storage box 5 more smoothly and avoids stagnation. It should be noted that by setting up the recycling mechanism 6, not only can the water used for cleaning be centrally recycled, making it convenient to reuse the water, but it can also effectively filter and remove impurities from the used water. This measure can ensure the cleanliness of the water and avoid blockage caused by impurities, thereby improving the efficiency and reliability of the workpiece cleaning operation. The principle of using the recycling mechanism 6 to filter and remove impurities from the used water is as follows: the filter plate 18 filters the used water source. Driven by the drive motor 22, the bidirectional threaded rod 19 rotates synchronously. Utilizing the threaded transmission between the bidirectional threaded rod 19 and the threaded sleeve 20, the threaded sleeve 20 moves linearly along the inside of the water blocking plate 26 after being subjected to force, which in turn drives the brush plate 21 to move synchronously. The brush plate 21 cleans the filter plate 18, thereby preventing impurities from clogging the filter plate 18.

[0028] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
