[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments. Example 1

[0023] In order to improve the reliability and accuracy of the dosing device, an automatic dosing device for the electroplating line is designed. The specific plan is as follows:

[0024] like Figure 1-2As shown, an automatic dosing device for an electroplating line includes a dosing cylinder 1, a delivery pump 2, an adjustable measuring cup 301 and a dosing component. The delivery pump 2 is connected to the dosing component and the dosing cylinder 1 respectively for dosing. An overflow pipe 5 is connected between the dosing component and the dosing cylinder 1. The dosing component is connected to the overflow pipe 5. An adjustable measuring cup 301 is arranged in the dosing component, and the adjustable measuring cup 301 is provided with a capacity adjustment rod 8.

[0025] Specifically, the dosing component is arranged above the dosing cylinder 1, and an outer cover 3 is provided on the outside of the dosing component. The outer cover 3 is a transparent structure, and a cover plate 302 is provided on the top of the outer cover 3. The outer cover 3 is a rectangular structure with an open top, and a supporting portion is provided on the top inner wall of the outer cover 3 for supporting the cover plate 302.

[0026] The overflow pipe 5 is disposed at the bottom of the outer cover 3 , and the upper end of the overflow pipe 5 is connected to the bottom of the adjustable measuring cup 301 .

[0027] The capacity adjustment rod 8 is provided with an adjustment nut 801, and the capacity of the measuring cup is controlled by screwing the adjustment nut 801. The upper part of the capacity adjustment rod 8 is screwed onto the cover plate 302. The staff can adjust the capacity of the internal adjustable measuring cup 301 by screwing the adjustment nut 801 from the outside.

[0028] The outside of the adjustable measuring cup 301 is provided with a capacity scale to facilitate observation and acquisition of the current capacity.

[0029] The adjustable measuring cup 301 itself is equivalent to a sleeve, which is sleeved on the lower part of the capacity adjustment rod 8. The capacity adjustment rod 8 adjusts the capacity of the measuring cup by sliding up and down in the measuring cup. The up and down sliding of the capacity adjustment rod 8 is achieved by rotating the adjustment nut 801.

[0030] The delivery pump 2 is a magnetic pump, which is a drug-resistant magnetic pump with a simple structure and more convenient maintenance. The liquid inlet end of the magnetic pump is connected to the lower part of the dosing cylinder 1, and the liquid outlet end of the magnetic pump is connected to the side of the dosing component through the delivery pipe 4.

[0031] An adjusting nut 801 is disposed at the upper end of the capacity adjusting rod 8 , and an outer wall of the adjusting nut 801 is provided with anti-slip patterns. The lower end of the capacity adjusting rod 8 is slidably connected to the inside of the adjustable measuring cup 301 .

[0032] A dust cover 201 with a handle is provided on the top of the dosing tank 1, which is convenient for opening to add medicine to the dosing tank 1 and to check the inside.

[0033] A solenoid valve 7 is provided on the dosing pipe 6. When the solenoid valve 7 is opened, the liquid in the measuring cup is discharged to the electroplating line. When the solenoid valve 7 is closed, the liquid is kept in the measuring cup. When the liquid reaches the dosing amount, the solenoid valve 7 is opened again to discharge it.

[0034] The device is connected with a controller, which controls the operation of the electromagnetic valve 7 and the magnetic pump for more convenient use.

[0035] The automatic dosing device of the present scheme only needs manual adjustment on the capacity of the adjusting measuring cup. After the capacity of the adjustable measuring cup 301 is adjusted, the device can operate fully automatically. The dosing component is connected with an overflow pipe 5 to avoid residual medicine liquid. The medicine liquid outside the adjustable measuring cup 301 can automatically flow back to the dosing tank 1; the medicine liquid in the dosing tank 1 is transported by a drug-resistant magnetic pump. The structure of the magnetic pump is simpler and easier to maintain. The bottom of the dosing component is connected with a dosing pipe 6, and the dosing pipe 6 is controlled by a solenoid valve 7. The outer cover 3 of the dosing component is a transparent structure, which is convenient for the staff to directly observe the adjustable measuring cup 301 inside and adjust the amount of medicine added each time to improve the accuracy of dosing. Example 2

[0036] In this embodiment, the structure of the device is basically the same as that of Embodiment 1, except that the capacity adjustment rod 8 is connected to a servo motor, which controls the forward and reverse rotation of the capacity adjustment rod 8, thereby controlling the capacity of the adjustable measuring cup 301, thereby realizing remote automatic control without manual operation.
