Description

Technical Field

[0001] The present invention relates to a field of copper foil additive flow adjustment equipment and an automatic adjustment system. Background Art

[0002] In the production of copper foil, additives are indispensable. By regulating the electrolysis process and the nucleation and growth mechanism of copper foil, additives significantly improve the physical properties (conductivity, ductility), chemical stability (anti-oxidation) and processing compatibility (such as PCB manufacturing) of copper foil. In order to control the amount of additives added, copper foil additive flow adjustment equipment and automatic adjustment systems are indispensable.

[0003] Today's copper foil additive flow adjustment equipment and automatic adjustment systems are in use, and additives are usually added through a peristaltic pump. However, when adding additives, the peristaltic pump is easily affected by changes in the liquid level in the storage barrel, which affects the accuracy of the injection amount. This error is often difficult to observe directly, posing a potential threat to the quality of the copper foil. Summary of the Invention

[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0033] The following describes an embodiment of the present invention based on its overall structure.

[0034] A copper foil additive flow adjustment device and automatic adjustment system, such as Figure 1-4 As shown, a liquid storage tank is used to store additives;

[0035] A peristaltic pump, the input end of which is connected to the liquid storage tank, is used to extract additives;

[0036] An ultrasonic flowmeter 8 is connected to the output end of the peristaltic pump and is used to measure the flow rate of the additive. The back of the ultrasonic flowmeter 8 is rotatably connected to a cover plate 3, and a magnetic plate 6 is provided on one side of the cover plate 3 to facilitate the overall installation.

[0037] A computer controller, electrically connected to the peristaltic pump and the ultrasonic flow meter 8, for controlling the output flow of the peristaltic pump;

[0038] The outer side of the ultrasonic flowmeter 8 is provided with a shell 1, and the inner walls on both sides of the shell 1 are provided with a fastening mechanism 4, the fastening mechanism 4 includes a mounting groove 401, and a fixed cylinder 4014 is fixed inside the mounting groove 401, the outer side of the fixed cylinder 4014 is rotatably connected to the rotating cylinder 4013, the outer side of the rotating cylinder 4013 is slidably connected to the sliding cylinder 403, the outer side of the sliding cylinder 403 is fixed with a gear ring 404, the inner wall of the mounting groove 401 is provided with teeth 402 that cooperate with the gear ring 404, the inner wall of the rotating cylinder 4013 is provided with a tooth groove 407, and slide grooves 408 are provided on both sides of the fixed cylinder 4014, and the inner side of the slide groove 408 is slidably connected to the rotating cylinder 4013. A slide rod 4011 is connected, and a clamping plate 4012 is fixed to the end of the slide rod 4011 to clamp the hose 7. A stud 4010 is rotatably connected inside the slide rod 4011, and a bevel gear 409 that meshes with the tooth groove 407 is fixed to the end of the stud 4010. A limit block 406 is provided on the inner wall of the slide cylinder 403, and a limit groove 405 that cooperates with the limit block 406 is provided on the outer side of the rotating cylinder 4013. The limit block 406 and the limit groove 405 cooperate with each other to facilitate the control of the sliding connection between the slide cylinder 403 and the rotating cylinder 4013. The output end and the outer side of the output end of the ultrasonic flowmeter 8 are both provided with a hose 7, and the hose 7 is located inside the fixed cylinder 4014;

[0039] A hose 7 is inserted into the mounting groove 401 so that it is located on the outside of the output end of the ultrasonic flowmeter 8. Repeat the above steps to install another hose 7 on the outside of the input end of the ultrasonic flowmeter 8. The slots and the clamping plate 4012 provided on the outside of the output end and the input end of the ultrasonic flowmeter 8 cooperate with each other to clamp the hose 7. Then, the slide 403 is pulled to slide the gear ring 404 away from the mounting groove 401. Then, the slide 403 is rotated to drive the rotating cylinder 4013 to rotate. The tooth groove 407 inside the rotating cylinder 4013 cooperates with the bevel gear 409. The bevel gear 409 rotates, and the bevel gear 409 drives the stud 4010 to rotate. The stud 4010 cooperates with the slide rod 4011. The slide rod 4011 moves inward, and the slide rod 4011 drives the clamping plate 4012 to move, thereby completing the purpose of clamping the hose 7.

[0040] See also Figure 1 and 4 A filtering mechanism 5 is provided inside the input end of the ultrasonic flowmeter 8, and the filtering mechanism 5 includes a first warehouse body 501 and a second warehouse body 502. A cavity 507 is provided inside the first warehouse body 501, and a filter plate 505 is fixed inside the cavity 507. One side of the filter plate 505 is rotatably connected to a mounting shaft 503, a scraper 506 is fixed to the bottom end of the outer side of the mounting shaft 503, and a fan blade 504 is fixed to the top end of the outer side of the mounting shaft 503. The first warehouse body 501 and the second warehouse body 502 are disassembled and connected by threads.

[0041] It can be understood that the threaded mechanism is set up to facilitate the disassembly between the first bin body 501 and the second bin body 502. At the same time, when the peristaltic pump extracts the additive and injects it into the ultrasonic flow meter 8 through the filter mechanism 5, the flow of the additive drives the fan blade 504 to rotate, and rotates through the installation shaft 503. The installation shaft 503 drives the scraper 506 to rotate to prevent impurities from clogging the filter plate.

[0042] See also Figure 1 An external connection 2 is provided on the top of the shell 1, and the external connection 2 is connected to the computer controller. A sensor is provided at the bottom of the liquid storage barrel for early warning of additive shortage inside the liquid storage barrel.

[0043] It should be noted that the data measured by the ultrasonic flow meter 8 can be input into the computer controller for comparison through the control external wiring, and the flow of the peristaltic pump can be controlled in time. The set sensor completes the liquid level warning function to monitor the liquid level height in the additive storage barrel and sends a warning signal when the liquid level is too low to ensure the continuity and stability of the additive supply. This function mainly sets the initial liquid volume of the additive (the volume of the storage barrel) and the low liquid level warning volume (the minimum acceptable liquid level volume of the storage barrel). When the copper foil production starts, the total flow rate is calculated by measuring the additive flow rate per minute, and the initial liquid volume is subtracted from the total flow rate to obtain the remaining liquid volume in the barrel. When the remaining liquid volume is lower than the minimum liquid level volume, the liquid level warning function is triggered. The warning signal can be sent to the staff through the enterprise WeChat workbench application to add additives in time.

[0044] Example

[0045] The specific steps are as follows:

[0046] S1: Insert a hose 7 into the installation slot 401 so that it is located outside the output end of the ultrasonic flow meter 8. Repeat the above steps to connect another hose 7 to the input end of the ultrasonic flow meter 8. Plug the external cable 2 into the computer controller.

[0047] S2: The hose 7 is fixed in position by the fastening mechanism 4, and then the hose at the input end is connected to the output end of the peristaltic pump, and then the peristaltic pump is started;

[0048] S3: The computer controller sets the flow rate of the peristaltic pump to Y. The peristaltic pump extracts the additive from the liquid storage tank and adds it after passing through the ultrasonic flow meter 8;

[0049] S4: The ultrasonic flowmeter 8 calculates the flow rate of the added additive, and the calculation result is X. The control logic is (X+Y) / 2=Z, and Z is the new flow value of the peristaltic pump;

[0050] S5: Compare X with Y and adjust X through control logic to better stabilize the amount of additive added.

[0051] It can be understood that the ultrasonic flow meter 8 can measure the actual flow in a timely manner and compare it with the rated flow value set by the peristaltic pump, and then adjust the rated value of the peristaltic pump through the control logic to stabilize the overall flow value and avoid the phenomenon that the actual flow of the peristaltic pump changes due to changes in the liquid level inside the liquid storage tank.
