[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-3 A pickling device for electroplating surface treatment in this embodiment includes a pickling box 1, and a lifting mechanism is installed outside the pickling box 1.

[0023] The lifting mechanism includes a fixed shell 4 and a screen frame 10. There are two fixed shells 4, which are respectively fixed on the left and right side walls of the pickling box 1. A driving motor 5 is fixedly installed on the inner bottom wall of the fixed shell 4. A threaded rod 6 is fixedly connected to the output shaft of the driving motor 5. The external thread of the threaded rod 6 is connected to a lifting block 7, and a lifting rod 8 is fixedly connected to one side of the lifting block 7.

[0024] It is understandable that the placement screen frame 10 is provided with a plurality of mesh holes so that the workpiece placed inside the placement screen frame 10 can fully contact with the pickling liquid. The placement screen frame 10 can be driven to move up or down by the upgrading mechanism, thereby facilitating the removal of the workpiece after pickling.

[0025] A limit member is installed between the lifting rod 8 and the placement screen frame 10, and the limit member includes a connecting plate 11. Fixed plates 15 are fixedly connected to the left and right sides of the placement screen frame 10, and a positioning block 17 is fixedly connected to the bottom of the fixed plate 15. A positioning groove 16 is opened on one side of the connecting plate 11, and the positioning block 17 is clamped in the inside of the positioning groove 16. A U-shaped groove 12 is opened on one side of the connecting plate 11, and a rotating shaft 13 is fixed in the inside of the U-shaped groove 12. The outside of the rotating shaft 13 is rotatably connected to a limit plate 14, and the limit plate 14 is attached to the surface of the fixed plate 15. The connecting plate 11 is an "L"-shaped plate, and the two connecting plates 11 are symmetrically arranged on the left and right.

[0026] It should be noted that the limiting plate 14 is attached to the top of the fixing plate 15 to limit the longitudinal displacement of the fixing plate 15 placed on the connecting plate 11, and the positioning block 17 is clamped in the positioning groove 16 to limit the lateral displacement of the fixing plate 15.

[0027] A stirring mechanism for stirring the pickling liquid is installed at the bottom of the pickling box 1. The stirring mechanism includes a rotating motor 2, which is fixedly installed at the bottom of the pickling box 1. A rotating rod is fixedly connected to the output shaft of the rotating motor 2. The rotating rod penetrates the pickling box 1 and extends to the interior of the pickling box 1. A plurality of stirring rods 3 are fixed to the side wall of the rotating rod.

[0028] See also Figure 1 A guide slot 9 is provided on the side of the fixed shell 4 away from the pickling box 1, and the lifting rod 8 passes through the guide slot 9 and extends to the outside of the pickling box 1. Support legs are fixed at the four corners of the bottom of the pickling box 1. A liquid outlet pipe is fixed through the pickling box 1, and a valve is installed on the liquid outlet pipe.

[0029] It should be noted that the two drive motors 5 are controlled to rotate synchronously by a dedicated synchronous controller. The dedicated synchronous controller is an existing mature technology and there is no need to elaborate on the specific principles of the synchronous controller.

[0030] The working principle of the above embodiment is as follows: when in use, the workpiece to be pickled is placed into the placement screen frame 10, and the threaded rod 6 is synchronously driven to rotate by the two driving motors 5. Under the limiting effect of the sliding connection between the lifting rod 8 and the guide slide groove 9, the lifting block 7 can drive the lifting rod 8 downward to slide in the guide slide groove 9, thereby driving the placement screen frame 10 to descend and immerse in the pickling liquid inside the pickling box 1. At the same time, the rotating motor 2 drives the stirring rod 3 to rotate to stir the internal pickling liquid to ensure the pickling effect. After the pickling is completed, the driving motor 5 is reversed, so that the lifting rod 8 can move upward to drive the placement screen frame 10 to move out of the pickling box 1, the rotating limit plate 14 moves from the surface of the fixed plate 15, and the fixed plate 15 is moved upward to move the positioning block 17 out of the positioning groove 16, so that the placement screen frame 10 can be disassembled, thereby facilitating the removal of the workpiece after pickling.
