Description

Technical Field

[0001] This application relates to the field of dip coating, and more specifically, to an automatic dip coating machine. Background Technology

[0002] In the existing technology, many parts, such as automotive parts, need to undergo dip coating treatment. The currently used automatic dip coating machine usually consists of a dip coating tank, a workpiece conveying device, and a drying device. Currently, when carrying out this process, the workpiece is first installed on the workpiece conveying device by the operator. The workpiece conveying device then transports the workpiece to the dip coating tank for dip coating treatment. After the treatment is completed, the workpiece conveying device transports the dip-coated workpiece to the drying device for drying. Finally, the workpiece is unloaded after drying.

[0003] Although automated operation is used, the process is not continuous. The workpiece needs a dipping time and a set drying time at the drying station. This results in the need to complete one batch of workpieces before processing the next batch, making the overall production process longer. Moreover, during the process of transporting the workpieces after dipping to the drying device, the dipping solution on the workpiece surface will drip due to its own gravity, resulting in uneven dipping solution on the workpiece surface during drying, which affects product quality.

[0004] Therefore, it is necessary to improve the dip coating machine to overcome the above-mentioned defects. Utility Model Content

[0005] The main objective of this application is to provide an automatic dip coating machine that is not only highly automated but also highly efficient in dip coating.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this application described herein.

These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0022] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0023] In addition, the term "multiple" should mean two or more.

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figures 1-2 As shown, an automatic dip coating machine includes a frame 1, a loading position at one end of the frame 1, a unloading position at the other end of the frame 1, a workpiece conveying mechanism between the loading position and the unloading position, and a drying mechanism fixedly mounted above the workpiece conveying mechanism. The loading position is provided with a dip coating tank 2. The workpiece conveying mechanism includes rotating rollers 9 rotatably mounted at the loading position and the unloading position, wheel structures fixedly mounted on both sides of the rotating rollers 9, a flexible conveying component wound around the wheel structures and cooperating with the wheel structures, and a workpiece mounting frame 10 fixedly mounted on the flexible conveying component. One of the rotating rollers 9 is driven to rotate by a drive mechanism.

[0026] Regarding the workpiece conveying mechanism, in this embodiment, the wheel structure adopts a sprocket 5, and the flexible conveying component is a chain 6 that cooperates with the sprocket 5. Alternatively, the wheel structure can adopt a synchronous pulley, and the flexible conveying component can be a synchronous belt that cooperates with the synchronous pulley. Comparing the two methods, the form of sprocket 5 and chain 6 is preferred because the workpiece needs to be dried at high temperature after dip coating, and the service life of sprocket 5 and chain 6 is better.

[0027] like Figure 1 As shown, regarding the drive, the drive mechanism includes a drive motor 7 and a reducer 8 connected to the drive motor 7. The output shaft of the reducer 8 is fixedly connected to the rotating roller 9 on the same axis. After the drive motor 7 reduces the speed through the reducer 8, it drives the rotating roller 9 to rotate. The wheel structure is fixedly set on both sides of the rotating roller 9, so the wheel structure rotates together with the rotating roller 9. Under the action of the chain 6, the chain 6 in the workpiece conveying mechanism moves as a whole, and the workpiece mounting frame 10 is fixed on the chain 6, thereby driving the workpiece mounting frame 10 to circulate.

[0028] like Figure 1 , Figure 2As shown, regarding drying, the drying device includes a first drying device 3 and a second drying device 4, which are arranged along the conveying direction of the workpiece. The drying temperature of the first drying device 3 is lower than that of the second drying device 4. By adopting a stepped drying method, the drying effect is greatly improved. The first drying device 3 uses a lower temperature to perform the first stage of drying on the workpiece after dip coating, which can effectively solidify the dip coating liquid. Then, the second drying device 4 is used for high-temperature drying, thereby improving the drying effect. The specific structure of the drying devices is the same for both, the only difference being the temperature. Specifically, both the first drying device 3 and the second drying device 4 include a drying cover covering the workpiece conveying mechanism, an air inlet connected to the drying cover, and a drying fan located at the air inlet.

[0029] To replenish the immersion coating solution in the immersion coating tank 2 in a timely manner, a reagent addition tank 12 is fixedly installed on the outside of the immersion coating tank 2 and connected to it. A circulation device is installed between the immersion coating tank 2 and the reagent addition tank 12. When the immersion coating solution in the immersion coating tank 2 is consumed to a set value, the valve 17 connected to the reagent addition tank 12 is opened to automatically replenish the reagent in the immersion coating tank 2. In addition, during the immersion coating process, a collection tank is also provided below the workpiece conveying mechanism. The reagent dripping during the conveying process flows into the immersion coating tank 2 through the collection tank. In order to filter impurities, preferably, the circulation device includes a circulation pipe 13 with one end connected to the immersion coating tank 2 and the other end connected to the reagent addition tank 12. A pump 14 and a filter 15 are respectively installed on the circulation pipe 13.

[0030] In addition, when it is necessary to replace the immersion coating solution in the immersion coating tank 2 as a whole or to clean the impurities deposited at the bottom, the immersion coating tank 2 is also equipped with a slag discharge pipe 16, and a valve 17 is provided on the slag discharge pipe 16. The valve 17 is opened to discharge the slag.

[0031] like Figure 1 As shown, the workpiece mounting frame 10 has several slots for inserting workpieces. When the operator inserts the workpiece into the slot, the workpiece mounting frame 10 flips upside down and moves forward when transported to the unloading position. During this process, the workpiece automatically comes out of the slot. At the same time, an inclined guide plate 11 is set at the unloading position. The workpiece automatically slides into the collection device along the guide plate 11, thus completing the entire process.

[0032] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
