[0027] Working principle: Physical vapor deposition coatings have been widely used for surface protection of cutting tools, molds and automotive parts. However, coated products often face problems of local wear and coating peeling during service, which leads to the subsequent accelerated failure of coated products. The coating industry requires the coated products to be stripped and then re-plated. The electrolyte can be guided to the interior of the stripping box 1 through the liquid guide tube 3. The metal coating is dissolved on the cathode through the action of an external power supply in the electrolyte, thereby achieving stripping. The product is immersed in the electrolyte and connected to the The positive electrode is placed on the upper surface, and the negative electrode is placed in the electrolyte. Driven by the electrode, a chemical reaction occurs between the electrolyte and the electroplating layer. In the presence of the electrolyte, a current is formed between the cathode and the anode, causing the coating ions on the surface of the anode to react chemically and form gas, ionize and precipitate. When the electrolytic stripping process is completed, the stripped parts are taken out of the electrolyte. When the product is stripped, the immersion height of the product and the electrolyte can be adjusted. After starting the servo motor 17, it will drive the screw rod 5 to transmit synchronously, and also drive the lifting block 7 threaded with it to move up and down. The other three lifting blocks 7 can move up and down at one end of the vertical rod 6, so that the position height of the bottom plate 11 can be adjusted, so the depth of the product and the electrolyte immersion can be adjusted, and it is also convenient to move the products that have been stripped upward uniformly, saving the time and energy of the staff to take the products one by one, and speeding up the material unloading. Under the operation of the micro motor 14, the transmission shaft 15 and the plurality of stirring bars 16 are driven to rotate at the same time, and the plurality of stirring bars 16 can stir the electrolyte. The stirring not only accelerates the mixing of the electrolyte, but also makes the temperature and concentration uniform, which is conducive to achieving a uniform stripping effect. The electrolyte can be immersed in the product through the plurality of leak holes 12. The plurality of lifting blocks 7 are supported by two side plates 8 and the support frame 9. The plurality of lifting blocks 7 move up and down at the same time, so that the support frame 9 and the bottom plate 11 move synchronously. The purpose of the plurality of anti-drop rods 10 is to shield the products that need to be stripped, so as to avoid the products from falling directly into the electrolyte and affecting the subsequent material unloading. The shell of the micro motor 14 is made of corrosion-resistant material and has good corrosion resistance.
