Description

Technical Field

[0001] This utility model relates to the field of electroplating production, specifically to an automatic quantitative addition device for copper additives. Background Technology

[0002] This utility model belongs to the field of electroplating production and is mainly applied to the copper additive addition process in the plating tank operation. It is a related equipment technology that ensures the smooth progress of the electroplating process and the formation effect of the plating layer.

[0003] Traditional methods of adding copper additives rely heavily on manual operation, lacking automated quantitative mechanisms, making precise replenishment difficult. Furthermore, they cannot monitor additive concentration changes in the plating bath in real time, and the absence of effective sensor feedback mechanisms leads to significant concentration fluctuations. Existing dosing equipment suffers from insufficient driving precision and lacks effective closed-loop control, which not only fails to guarantee the stability of plating quality but also results in excessive consumption of copper additives, reducing economic efficiency during use. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned shortcomings by providing an automatic quantitative addition device for copper additives, which solves the technical problems of relying heavily on manual operation, lacking an automated quantitative mechanism, and making it difficult to achieve accurate replenishment.

[0005] The purpose of this utility model is achieved through the following method: an automatic quantitative addition device for copper additives, comprising a base, a magnetic fixing plate at the bottom of the base, a fixing block on one side of the upper surface of the base, a storage tank mounted on the base via the fixing block, a protective box on the other side of the upper surface of the base opposite the storage tank, a controller fixedly mounted on one side inside the protective box, a backup power supply located on the side of the controller within the protective box, a conduit connected to one side of the protective box, and a conductivity sensor connected to the other end of the conduit. The conduit is connected to the controller. A flexible conduit is provided at one end of the conduit between the protective box and the conductivity sensor. A conduit clamp is provided on the upper surface of the base near the conductivity sensor. A conduit is connected to the outlet of the storage tank. A dosing pump is provided on the base on one side of the storage tank via a mounting base. The storage tank is connected to the input end of the dosing pump via a conduit. An add-in pipe is connected to the output end of the dosing pump. A drip tip is provided at the other end of the add-in pipe. The dosing pump is electrically connected to the controller. An add-in pipe clamp is provided on the base on one side of the dosing pump.

[0006] Preferably, the storage tank has a capacity of 20L, the outer wall of the storage tank is provided with graduation marks, and the dosing pump is a stepper motor.

[0007] The scale on the outer wall of the storage tank can intuitively reflect the remaining amount of copper additive inside, making it easy for operators to replenish in time and avoid interruption of addition due to lack of liquid; the stepper motor type dosing pump has the characteristics of stable operation and precise output control, and can achieve uniform quantitative addition according to the controller's instructions, effectively avoiding the deviation of the addition amount. At the same time, its structural design is easy to maintain and can adapt to long-term continuous operation conditions.

[0008] Preferably, a filter is provided on the inner wall of the liquid storage tank near the liquid outlet, and a guide vane is fixedly installed on the inner wall of the liquid storage tank.

[0009] The filter on the inner wall of the storage tank can intercept impurities in the copper additive, preventing them from entering the conduit with the liquid, thereby avoiding blockage or wear inside the dosing pump and ensuring the normal operation of the dosing pump; the guide vanes can guide the liquid in the storage tank to form an orderly flow, reduce the deposition of additives at the bottom of the tank, and ensure uniform additive concentration in the tank.

[0010] Preferably, at least two magnetic fixing plates are provided, which are evenly distributed along the bottom of the base, and the adsorption surface of the magnetic fixing plates is covered with an anti-slip and wear-resistant layer.

[0011] Multiple magnetic fixing plates evenly distributed along the bottom of the base enhance the stability of the device and the mounting surface, making the device less prone to displacement or shaking during operation, and adapting to different types of metal installation scenarios; the anti-slip and wear-resistant layer on the adsorption surface not only increases the friction between the magnetic fixing plates and the mounting surface, further improving the fixing effect, but also reduces the wear of the adsorption surface.

[0012] Preferably, the backup power source is a rechargeable lithium battery, and the outer wall of the protective box is provided with a charging interface and a power indicator light that are electrically connected to the backup power source. The backup power source is electrically connected to the controller and the dosing pump.

[0013] The charging port on the outer wall of the protective box provides convenience for daily power replenishment of the backup power supply. The power indicator light can intuitively reflect the remaining power of the backup power supply, allowing operators to judge in advance whether charging is needed and avoid sudden power outages affecting the operation of the device. The stable electrical connection between the backup power supply and the controller and dosing pump can quickly switch power supply when the main power supply fails, ensuring that the controller's command transmission and the dosing pump's quantitative dosing function remain effective.

[0014] Preferably, the fixing block is detachably connected to the base by bolts, and the height of the fixing block can be adjusted by shims.

[0015] The bolt-type detachable connection between the fixing block and the base makes it easy for operators to disassemble or install the liquid storage tank according to actual needs, reducing the difficulty of cleaning, maintaining or replacing the liquid storage tank. The design of adjusting the height of the fixing block with shims can flexibly adapt to liquid storage tanks of different specifications, or adjust the horizontal height of the liquid storage tank according to the plane accuracy of the installation scene, ensuring smooth connection between the liquid outlet of the liquid storage tank and the conduit, and avoiding obstruction of liquid flow due to height deviation, which would affect the transfer efficiency of the additive.

[0016] The beneficial effects of this invention are as follows: An automatic quantitative addition device for copper additives enables precise addition of copper additives without manual intervention. A conductivity sensor monitors the concentration in the plating bath in real time, and the data is promptly fed back to the controller, forming a closed-loop sensor feedback system that effectively solves the problem of concentration fluctuations. The backup power supply ensures the continuity of the device's operation, preventing sudden power outages from affecting the addition process. The precise drive of the dosing pump, combined with closed-loop control, ensures stable plating quality while reducing unnecessary additive consumption, thus improving economic efficiency.

The system is connected in four phases. A flexible hose 107 is provided at one end of the conduit 106 located between the protective box 103 and the conductivity sensor 108. A conduit clamp 109 is provided on the upper surface of the base 100 near the conductivity sensor 108. A conduit 112 is connected to the outlet of the storage tank 111. A dosing pump 113 is provided on one side of the base 100 via a mounting base. The storage tank 111 is connected to the input end of the dosing pump 113 via the conduit 112. An adder tube 114 is connected to the output end of the dosing pump 113. A dripper 115 is provided at the other end of the adder tube 114. The dosing pump 113 is electrically connected to the controller 104. An adder tube clamp 116 is provided on one side of the base 100 near the dosing pump 113.

[0023] The storage tank 111 has a capacity of 20L and is equipped with graduation marks on its outer wall. The dosing pump 113 is a stepper motor.

[0024] The scale on the outer wall of the storage tank 111 can intuitively reflect the remaining amount of copper additive inside, making it convenient for operators to replenish in time and avoid interruption of addition due to lack of liquid; the stepper motor type dosing pump 113 has the characteristics of stable operation and precise output control, and can achieve uniform quantitative addition according to the instructions of the controller 104, effectively avoiding the deviation of the addition amount. At the same time, its structural design is easy to maintain and can adapt to long-term continuous operation conditions.

[0025] A filter 110 is provided on the inner wall of the liquid storage tank 111 near the liquid outlet, and a guide vane 117 is fixedly installed on the inner wall of the liquid storage tank 111.

[0026] The filter 110 on the inner wall of the storage tank 111 can intercept impurities in the copper additive, preventing impurities from entering the conduit 112 with the liquid, thereby avoiding blockage or wear inside the dosing pump 113 and ensuring the normal operation of the dosing pump 113; the guide vane 117 can guide the liquid in the storage tank 111 to form an orderly flow, reduce the deposition of additives at the bottom of the tank, and ensure that the additive concentration in the tank is uniform.

[0027] At least two magnetic fixing plates 101 are provided, and the magnetic fixing plates 101 are evenly distributed along the bottom of the base 100. The adsorption surface of the magnetic fixing plates 101 is covered with an anti-slip and wear-resistant layer.

[0028] Multiple magnetic fixing plates 101 evenly distributed along the bottom of the base 100 can enhance the stability of the device and the mounting surface, making the device less prone to displacement or shaking during operation, and adapting to different types of metal installation scenarios; the anti-slip and wear-resistant layer of the adsorption surface can not only increase the friction between the magnetic fixing plate 101 and the mounting surface, further improving the fixing effect, but also reduce the wear of the adsorption surface.

[0029] The backup power supply 105 is a rechargeable lithium battery. The outer wall of the protective box 103 is provided with a charging interface and a power indicator light that are electrically connected to the backup power supply 105. The backup power supply 105 is electrically connected to the controller 104 and the dosing pump 113.

[0030] The charging port on the outer wall of the protective box 103 provides convenience for daily power replenishment of the backup power supply 105. The power indicator light can intuitively reflect the remaining power of the backup power supply 105, making it convenient for operators to judge in advance whether charging is needed and avoid sudden power outages affecting the operation of the device. The backup power supply 105 has a stable electrical connection with the controller 104 and the dosing pump 113, which can quickly switch power supply when the main power supply fails, ensuring that the command transmission of the controller 104 and the quantitative dosing function of the dosing pump 113 continue to be effective.

[0031] The fixing block 102 is detachably connected to the base 100 by bolts, and the height of the fixing block 102 can be adjusted by shims.

[0032] The bolted detachable connection between the fixing block 102 and the base 100 facilitates the disassembly or installation of the liquid storage tank 111 by operators according to actual needs, reducing the difficulty of cleaning, maintaining or replacing the liquid storage tank 111. The design of adjusting the height of the fixing block 102 with shims can flexibly adapt to different specifications of liquid storage tanks 111, or adjust the horizontal height of the liquid storage tank 111 according to the plane accuracy of the installation scene, ensuring smooth connection between the liquid outlet of the liquid storage tank 111 and the conduit 112, and avoiding obstruction of liquid flow due to height deviation, which would affect the transfer efficiency of the additive.

[0033] The working process of the automatic copper additive quantitative addition device in this embodiment is as follows: After the base 100 is stably installed by the bottom magnetic fixing plate 101, the conductivity sensor 108 connected to the conduit 106 on one side of the protective box 103 monitors the concentration of copper additive in the plating tank in real time. The monitoring data is transmitted to the controller 104 in the protective box 103 through the conduit 106 and the telescopic hose 107 therein. When the concentration is lower than the preset threshold, the controller 104 sends a command to the dosing pump 113, and the copper additive in the storage tank 111 is filtered for impurities and guided by the inner wall filter 110. After the blades 117 guide the uniform flow, the additive enters the stepper motor type dosing pump 113 through the conduit 112. The dosing pump 113 injects the quantitative additive into the plating tank through the addition tube 114 and the dropper 115 according to the instructions. When the conductivity sensor 108 detects that the concentration has risen back to the target value, the controller 104 controls the dosing pump 113 to stop working, forming a sensor feedback closed loop. The backup power supply 105 in the protective box 103 continuously supplies power to the controller 104 and the dosing pump 113 when the main power supply fails, ensuring the continuous operation of the device and realizing the precise quantitative automatic addition of copper additive.
