Description

Technical Field

[0001] The utility model relates to the technical field related to metal activation, in particular to an activation device for metal surface treatment. Background Art

[0002] Among metal surface treatments, electroplating is a processing method used to prevent metal oxidation. The "activation" mentioned in electroplating generally refers to the process of corroding the plated parts with acid or alkaline solutions to dissolve the oxide film on the surface to expose the active metal interface, so as to ensure the bonding strength between the electroplating layer and the substrate.

[0003] The existing activation process usually removes the oxide film on the surface of the metal part by immersion. However, the reaction speed of activating the metal surface by immersion alone is slow, and it is difficult to evenly remove the oxide film on the surfaces of the metal part. Utility Model Content

[0028] Among them, a mounting seat 11 for supporting the activation tank 1 is provided at the lower end of the activation tank 1, and a limiting cylinder for fixing the gas elbow 4 is provided on the bottom plate of the mounting seat 11. By setting the mounting seat 11, the activation tank 1 can be supported, and the limiting cylinder on the activation tank 1 can prevent the gas elbow 4 from rotating with the triangular sprayer 2.

[0029] Among them, a motor 12 is fixedly installed on the mounting seat 11, and a gear 13 meshing with the ring gear 3 is provided on the output end of the motor 12. By arranging the motor 12 and the gear 13, when the motor 12 is working, it can drive the gear 13 to rotate, thereby utilizing the meshing relationship between the ring gear 3 and the gear 13 to drive the triangular sprayer 2 to rotate in the activation tank 1.

[0030] Among them, a bearing 14 is provided at the lower end of the triangular sprayer 2, and the upper end of the gas elbow 4 is located in the lower end of the triangular sprayer 2 and fixedly connected to the inner ring of the bearing 14. By providing the bearing 14, the triangular sprayer 2 will not drive the gas elbow 4 to rotate together when rotating.

[0031] Among them, the triangular sprayer 2 is provided with a plurality of single nozzles 15 arranged along the support rod, and the lower surface of each support rod of the triangular sprayer 2 is provided with a scraper 16 that contacts the upper surface of the bottom plate of the activation tank 1. By providing the single nozzle 15, the triangular sprayer 2 can evenly spray the air used to stir the solution, and by providing the scraper 16, the debris on the upper surface of the bottom plate of the activation tank 1 can be swept into the recovery bucket 5.

[0032] Among them, both sides of the upper edge of the carrying basket 7 are provided with hanging ears 17, and the output ends of the two electric push rods 6 on the same side are connected to the corresponding hanging ears 17, and one side of the carrying basket 7 is provided with an opening for the entry and exit of the containing frame 8. By setting the hanging ears 17, the position of the carrying basket 7 on the activation tank 1 can be limited to prevent the carrying basket 7 from falling into the activation tank 1.

Then, the metal parts to be activated are placed in the containing frame 8, and then the containing frame 8 with the metal parts is placed in the carrying basket 7. The carrying basket 7 is lowered into the activation tank 1 by the electric push rod 6, and then the motor 12 is started. When the output end of the motor 12 rotates, the triangular sprayer 2 is driven to rotate in the activation tank 1 through the meshing action of the gear 13 and the gear ring 3. The triangular sprayer 2 is capable of stirring the solution in the activation tank 1. Since a bearing 14 is provided between the gas elbow 4 and the triangular sprayer 2, in cooperation with a limit cylinder connected to the activation tank 1, the triangular sprayer 2 will not drive the gas elbow 4 to rotate together when rotating, and the gas entering from the gas elbow 4 will be injected into the triangular sprayer 2 and sprayed out from the single nozzle 15 on the triangular sprayer 2, thereby stirring the solution in the activation tank 1, ensuring that the solution is fully in contact with the surfaces of the metal parts, and accelerating the activation reaction on the metal surface;

[0035] At the same time, during the rotation of the triangular sprayer 2, the scraper 16 below the triangular sprayer 2 will clean the debris on the upper surface of the bottom plate of the activation tank 1, so that the debris on the bottom plate of the activation tank 1 falls into the recovery bucket 5, which is convenient for the recovery of these debris. After the activation of the metal parts is completed, the carrying basket 7 is lifted by the electric push rod 6. During the lifting and lowering of the carrying basket 7, the arc-shaped sprayer 9 will spray the pure water input therein in the form of mist, and then rinse the metal gold therein to remove the solution residue on the metal parts. When the carrying basket 7 is lifted to the highest position, the containing frame 8 in the carrying basket 7 can be dragged onto the pallet 10, and the staff will take out the rinsed metal parts, and then place another batch of metal parts to be activated in the carrying basket 7, and repeat the above operation, which can greatly reduce the workload of the staff.
