Description

Technical Field

[0001] The utility model relates to the technical field of fastener anti-corrosion electroplating, in particular to an electroplating device for fastener anti-corrosion. Background Art

[0002] Electroplating is a process that uses the principle of electrolysis to attach a layer of metal film to the surface of metal fasteners, thereby improving the corrosion resistance of the fasteners. When processing fasteners, existing electroplating devices often use roller plating to improve the efficiency and effect of electroplating. That is, the fasteners are placed in a rotatable drum. The drum is set at an angle. The position of the fasteners is continuously changed through the slow rotation of the drum to avoid adhesion between the fasteners, so as to achieve electroplating of the fasteners. When taking out the fasteners in the drum, it is necessary to control the overall flipping of the drum, resulting in the existing electroplating device occupying a large space, and it is not convenient to receive the fasteners that fall from the drum, which is not convenient to use.

DETAILED DESCRIPTION

[0015] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings.

[0016] like Figure 1-3As shown, a fastener anti-corrosion electroplating device comprises an electroplating tank 1, a side tube 2 which is connected to the electroplating tank 1 is arranged on one side of the electroplating tank 1, the side tube 2 is arranged obliquely, a leakage screen tube 3 is arranged inside the side tube 2, both ends of the leakage screen tube 3 are opened, a ring plate 4 is arranged at one end of the leakage screen tube 3, the ring plate 4 is abutted against one end of the side tube 2, a horizontal plate 5 is arranged at both ends of the leakage screen tube 3, two symmetrical fixing rods 6 are arranged between the two horizontal plates 5, a leakage plate 7 which is slidably connected to the fixing rod 6 is arranged inside the leakage screen tube 3, and the two horizontal plates 5 are arranged between the two horizontal plates 5. A screw rod 8 is rotatably connected between the plates 5, and the screw rod 8 is threadedly connected to the leakage plate 7. A shell 9 is provided on the outer surface of the electroplating tank 1, and a first motor 10 is provided inside the shell 9. The output end of the first motor 10 passes through the electroplating tank 1 and is fixedly connected to one end of the screw rod 8. A fixed plate 11 is provided at the upper end of the electroplating tank 1, and a second motor 12 is provided on one side of the fixed plate 11. The output end of the second motor 12 is fixedly connected to the cross plate 5, and the output end of the second motor 12 drives the leakage screen cylinder 3 to rotate in the side cylinder 2 and the electroplating tank 1 through the cross plate 5.

[0017] The second motor 12 is a servo brake motor. When the output end of the second motor 12 stops rotating, its output end can lock the position. The first motor 10 is an ordinary servo motor. When the output end of the first motor 10 stops rotating, its output end cannot lock the position.

[0018] When electroplating fasteners, first add a proper amount of plating liquid to the electroplating tank 1, and then put a certain number of fasteners into the strainer tube 3 from the position of the side tube 2. The leak plate 7 at the bottom of the strainer tube 3 can prevent the fasteners from falling from the strainer tube 3 into the electroplating tank 1. After the fasteners are put in, start the second motor 12. The second motor 12 drives the strainer tube 3 to rotate in the electroplating tank 1 through the cross plate 5, and turns the fasteners in the strainer tube 3 over. In the process of electroplating the surface of the fasteners, adhesion between the fasteners can be avoided, and the electroplating effect of the fasteners can be improved. The rotation speed of the strainer tube 3 is at most two seconds per revolution to avoid excessively high rotation speeds that cause serious collisions between fasteners and damage to the fasteners and the electroplating layer.

[0019] When the screen cylinder 3 rotates, the fixed rod 6, the leakage plate 7 and the screw rod 8 all rotate following the output end of the second motor 12, and the first motor 10 also rotates synchronously following the second motor 12. When the first motor 10 rotates, it can prevent the screw rod 8 and the leakage plate 7 from rotating relative to each other, so as to prevent the leakage plate 7 from rotating along the screw rod 8 in the screen cylinder 3.

[0020] When the electroplating of the fasteners is completed and the fasteners need to be taken out from the strainer tube 3, the output end of the second motor 12 stops rotating. After the output end of the second motor 12 stops rotating, the cross plate 5 connected to the output end of the second motor 12 needs to be stopped at a position parallel to the placement surface of the electroplating tank 1. When the cross plate 5 stops, since the second motor 12 is a servo brake motor, the output end position of the second motor 12 is locked, thereby locking the position of the strainer tube 3 and the fixed rod 6. Then the first motor 10 is controlled to start, and the output end of the first motor 10 drives the screw rod 8 to rotate. The screw rod 8 is connected to the leak plate 7 through a thread, driving the leak plate 7 to move in a straight line along the screw rod 8 and the fixed rod 6. When the leak plate 7 moves, it pushes the fasteners in the strainer tube 3 from the bottom of the strainer tube 3 to the top of the strainer tube 3, and the staff can collect and transfer the pushed out fasteners.

[0021] After all the fasteners are taken out from the strainer tube 3, before the fasteners are put back into the strainer tube 3, the first motor 10 can be used to drive the strainer plate 7 to move downward along the screw rod 8 by an end distance, so that a certain space is reserved between the strainer plate 7 and the upper end of the strainer tube 3. After the space is reserved, the unplated fasteners are put into the space. By setting the reserved space, the moving distance of the fasteners in the strainer tube 3 can be reduced to reduce the collision between the fasteners. After the fasteners are put in, the first motor 10 controls the strainer plate 7 to move to the bottom of the strainer tube 3. When the second motor 12 drives the strainer tube 3 to rotate, the fasteners on the strainer tube 3 will gradually enter the electroplating solution of the electroplating tank 1 to realize the electroplating treatment of the fasteners.

[0022] Furthermore, an electromagnetic heater 13 is arranged below the electroplating tank 1, a metal plate 14 is arranged at the bottom of the electroplating tank 1, and a temperature sensor 15 is arranged inside the electroplating tank 1. The electromagnetic heater 13 first heats the metal plate 14, and after the metal plate 14 is heated, the plating liquid in the electroplating tank 1 is heated. After the plating liquid is heated, the electroplating efficiency can be improved, thereby improving the production efficiency. An upper limit and a lower limit are set for the temperature of the plating liquid. For example, the upper limit is 50°C and the lower limit is 40°C. When the temperature of the plating liquid reaches the upper limit, the temperature sensor 15 detects and transmits the signal to the electromagnetic heater 13, and the electromagnetic heater 13 stops heating the metal plate 14. When the temperature of the plating liquid is lower than 40°C, the temperature sensor 15 detects and transmits the signal to the electromagnetic heater 13, and the electromagnetic heater 13 reheats the metal plate 14 to increase the temperature of the plating liquid.

[0023] Furthermore, the upper end of the electroplating tank 1 is open, and an end cover 16 is provided at the upper end opening of the electroplating tank 1. The end cover 16 can be used to conveniently close the upper end opening of the electroplating tank 1 to prevent more impurities from entering the electroplating tank 1 through the upper end opening of the electroplating tank 1.

[0024] Furthermore, a drain valve 17 is provided on the electroplating tank 1 , and the drain valve 17 is used to discharge the electroplating liquid in the electroplating tank 1 , so as to facilitate replacement of the electroplating liquid in the electroplating tank 1 .

[0025] Furthermore, an arc-shaped material guide plate 18 is provided on the outer surface of the side tube 2. When the fasteners in the mesh tube 3 are pushed outward through the leakage plate 7, the fasteners are first pushed onto the material guide plate 18. The staff uses the material guide plate 18 to collect the fasteners that have completed electroplating, which facilitates the collection of the fasteners. At the same time, the arc-shaped material guide plate 18 can also prevent the fasteners from falling to the outside of the material guide plate 18 through the two sides of the material guide plate 18.

[0026] This type of electroplating device does not need to control the flipping of the screen cylinder 3. By controlling the movement of the leak plate 7, all the fasteners in the screen cylinder 3 can be pushed out, thereby greatly reducing the space occupied by the electroplating device and eliminating the flipping of the screen cylinder 3, making the operation process safer. The moving speed of the fasteners is controlled by the moving speed of the leak plate 7, which is also convenient for receiving the fasteners dropped from the screen cylinder 3, and is easy to use.
