[0031] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0032] like Figure 1-5 As shown, a dipping device for Dacromet coating comprises:

[0033] Rack 1;

[0034] A dipping tank 2, which is mounted on the frame 1 and is provided with a dipping chamber 21 for storing the Dacromet coating solution;

[0035] The lifting device includes a lifting member 31, a hoisting assembly and a placement basket 33. The lifting member 31 is slidably mounted on the frame 1, and the hoisting assembly is mounted on the lifting member 31. The lifting device is suitable for being driven to slide up and down, and the hoisting assembly is suitable for hoisting the placement basket 33. The placement basket 33 is suitable for placing workpieces to be dipped;

[0036] The driving device is connected to the lifting device, and the driving device is suitable for driving the lifting member 31 to slide up and down on the frame 1 so that the placement basket 33 on the hanging assembly is immersed in the Dacromet coating liquid in the dipping chamber 21 during the sliding process.

[0037] Specifically, Figure 1-5 As shown, the frame 1 is provided with a base platform 11 , and the dipping tank 2 is installed on the base platform 11 of the frame 1 .

[0038] Specifically, Figure 1-5 As shown, a fixing frame 111 is also provided on the base platform 11 , and the fixing frame 111 is fixedly connected to the base platform 11 , and the dipping tank 2 is suitable for being clamped by the fixing frame 111 . The setting of the fixing frame 111 enables the dipping tank 2 to remain stable on the base platform 11 .

[0039] Specifically, Figure 1-5 As shown, the lifting assembly includes two lifting arms 321 for lifting and placing the basket 33.

[0040] Specifically, Figure 1-5 As shown, the hanging arm 321 is movably connected to the lifting member 31 , and a hook seat 322 is provided at the top of the hanging arm 321 .

[0041] In this embodiment, the lifting member 31 is provided with two supporting arms, and the hanging arm 321 is sleeved on the supporting arms. The hanging arm 31 is also provided with a locking mechanism, which can be a fastening bolt. Loosening the locking mechanism can allow the two hanging arms 321 to slide freely on the supporting arms to adjust the distance between the two hanging arms 321 to adapt to different sizes of placement baskets 33. Tightening the locking mechanism prevents the placement basket 33 from falling due to shaking during the dipping process.

[0042] Specifically, Figure 1-3 As shown, the basket 33 is provided with a handle, which is suitable for being snapped onto the hook seat 322 .

[0043] Specifically, the lifting member 31 is slidably mounted on the frame 1 through at least one guide rail and slider pair; wherein,

[0044] The guide rail slider pair includes:

[0045] A guide rail mounted on the rack 1;

[0046] A sliding block is arranged on the lifting member 31 and cooperates with the guide rail.

[0047] Specifically, Figure 3-5 As shown, the driving device includes a connecting seat 41 and a cylinder 42 . The connecting seat 41 is installed on the base platform 11 . The cylinder 42 is hinged on the connecting seat 41 . The movable end of the cylinder 42 is hinged to the lifting member 31 .

[0048] Specifically, Figure 1-5 As shown, the dipping tank 2 is also provided with a drain port 22 suitable for discharging the Dacromet coating liquid.

[0049] Specifically, the dipping device for Dacromet coating also includes an air jet device, which includes an air pump 51 and at least one nozzle. The air pump 51 is installed on the outer wall of the dipping tank 2, and the nozzle is installed on the inner wall of the dipping tank 2. The nozzle is connected to the air pump 51.

[0050] In this embodiment, three nozzles are evenly arranged on the inner wall of the dipping tank 2, and the nozzles are inclined 45 degrees toward the bottom of the dipping tank 2. When the air pump 51 starts working, the nozzles spray airflow toward the dipping tank 2, and the airflow drives the Dacromet coating liquid to rotate and stir in the dipping chamber 21, thereby avoiding the Dacromet coating liquid from sinking to the bottom due to long-term standing, resulting in uneven coating of the workpiece during dipping.

[0051] In the present invention, a proper amount of Dacromet coating liquid is added to the dipping tank 2, and the workpieces to be coated are placed in the placement basket 33, ensuring that the workpieces are arranged neatly and do not collide with each other. The placement basket 33 is lifted using the hook seat 322 on the lifting assembly, ensuring that the placement basket 33 is firmly suspended on the lifting arm 321;

[0052] The driving device is started, and the driving device drives the lifting member 31 to move up and down through the cylinder 42. The lifting member 31 slides smoothly on the frame 1 through the guide rail slider pair, and the placement basket 33 on the lifting assembly is slowly immersed in the Dacromet coating liquid in the dipping tank 2. After the placement basket 33 is completely immersed in the coating liquid, it is kept for a period of time. During this process, the jet device is started, and the air pump 51 sprays the coating liquid through the nozzle to increase the fluidity of the coating liquid, so that the coating liquid covers the surface of the workpiece more evenly;

[0053] After the predetermined dipping time, the driving device drives the lifting member 31 to slowly lift the placement basket 33 out of the coating liquid, let it stand for a while, and let the excess coating liquid naturally drip back into the dipping tank 2 through the mesh holes of the placement basket 33. The coated workpiece is placed in a safe place for natural drying or for the next step of processing.

[0054] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
