Benefits of technology

[0014] 1) The set out of the liquid outlet frame allows the copper foil to undergo basic pickling as it passes through the two outlet frames. Then, through the interaction of the inner and outer ring columns, the pickling agent used in the previous outlet frame can move to the outer ring column and then flow to the inner ring column of another set through the delivery pipe. Thus, the pickling agent used in the outlet frame of the next cleaning can pass through the outlet frame to perform preliminary pickling on the copper foil. This allows the pickling agent to be used twice in the outlet frame, reducing the loss of pickling agent.

Description

Technical Field

[0001] This invention belongs to the field of copper foil surface treatment technology, and specifically relates to a copper foil surface treatment device. Background Technology

[0002] Copper foil is an anionic electrolytic material, a thin, continuous metal foil deposited on the substrate layer of a circuit board, serving as a conductor. It easily adheres to insulating layers, receives printed protective layers, and forms circuit patterns after etching. Copper foil has low surface oxygen properties, allowing it to adhere to various substrates such as metals and insulating materials, and possesses a wide operating temperature range. It is primarily used for electromagnetic shielding and antistatic purposes. Placing conductive copper foil on a substrate, combined with a metal substrate, provides excellent conductivity and electromagnetic shielding. Copper foil surface treatment requires cleaning, degreasing, pickling, neutralization, washing, oxidation, re-washing, and drying. This process makes the copper foil surface smooth and clean, with better corrosion resistance and oxidation resistance. Currently, copper foil surface treatment equipment mainly suffers from the following consensus-based defects:

[0003] In traditional copper foil surface treatment operations, due to the thinness of the copper foil, acid pickling may be required during the treatment process. However, in traditional treatment devices, after the initial acid pickling with the pickling agent, the agent flows in the same pool. This causes the agent content in different parts of the pool to increase as the copper foil passes through, and the amount of agent in the pool will continue to increase, reducing the effectiveness and efficiency of continuous copper foil treatment. Summary of the Invention

[0004] The purpose of this invention is to provide a copper foil surface treatment apparatus, which aims to solve the problem in the prior art where, after the initial pickling with pickling agent, the agent flows in the same pool, causing the agent content in different parts of the pool to increase as the copper foil passes through the pool, and the amount of agent in the pool to continuously increase.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A copper foil surface treatment device includes a liquid storage tank. Four outer ring columns are fixedly installed on the inner wall of the liquid storage tank. Inner ring columns are fixedly installed on the inner sides of the four outer ring columns. The top and bottom of each inner ring column are connected to a first telescopic tube. The top of the first telescopic tube is connected to an outlet frame. Two inlet rings are slidably connected to the outer side of the outlet frame. The two ends of the inlet rings are connected to second telescopic tubes. The outlets of the second telescopic tubes are respectively connected to the two ends of the outer ring columns. One end of one of the outer ring columns is connected to a conveying pipe. The end of the conveying pipe is connected to the outer side of the inner ring column.

[0007] As a preferred embodiment of the present invention, a main liquid pipe is connected to the outer side of one of the inner annular columns, and a drain pipe is connected to the bottom of the other outer annular column.

[0008] As a preferred embodiment of the present invention, multiple limiting springs are fixedly installed on the outer side of the liquid inlet ring, and the other end of the multiple limiting springs is fixedly connected to the inner side wall of the liquid outlet frame.

[0009] In a preferred embodiment of the present invention, the liquid outlet frame is rotatably connected to multiple guide rods, and a linkage gear is fixedly installed on the outer side of the top of the multiple guide rods. The outer side of the linkage gear is meshed with a toothed chain.

[0010] As a preferred embodiment of the present invention, a motor is fixedly installed inside the liquid outlet frame, and a transition gear is fixedly installed at the top of one of the guide rods and at the output end of the motor.

[0011] In a preferred embodiment of the present invention, connecting frames are fixedly installed at both ends of the liquid outlet frame, and two electric telescopic rods are fixedly installed at the other ends of the two connecting frames. The fixed ends of the two electric telescopic rods are fixedly connected to the inner wall of the liquid storage tank, and the outer side of the connecting frame is slidably connected to the inner wall of the liquid storage tank.

[0012] In a preferred embodiment of the present invention, a switch panel is fixedly installed on the outside of the liquid storage tank. A motor switch and an electric telescopic rod switch are fixedly installed on the surface of the switch panel. The motor is electrically connected to an external power source through the motor switch, and the electric telescopic rod is electrically connected to an external power source through the electric telescopic rod switch.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1) The set out of the liquid outlet frame allows the copper foil to undergo basic pickling as it passes through the two outlet frames. Then, through the interaction of the inner and outer ring columns, the pickling agent used in the previous outlet frame can move to the outer ring column and then flow to the inner ring column of another set through the delivery pipe. Thus, the pickling agent used in the outlet frame of the next cleaning can pass through the outlet frame to perform preliminary pickling on the copper foil. This allows the pickling agent to be used twice in the outlet frame, reducing the loss of pickling agent.

[0015] 2) The guide rod inside the liquid outlet frame allows the agent to be sprayed out to the bottom. Due to the bottom outlet of the liquid outlet frame, the agent can bounce back into the liquid inlet ring after pickling. The liquid inlet ring can then collect this liquid and send it to the next set of liquid outlet frames for reuse, reducing the waste of resources in the surface treatment process.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figure 1-5 The present invention provides the following technical solution: a copper foil surface treatment device, comprising a liquid storage tank 1, four outer ring columns 2 fixedly installed on the inner side wall of the liquid storage tank 1, and inner ring columns 3 fixedly installed on the inner side of the four outer ring columns 2. The top and bottom of the inner ring columns 3 are connected to a first telescopic tube 4, the top end of the first telescopic tube 4 is connected to an outlet frame 5, and two inlet rings 6 are slidably connected to the outer side of the outlet frame 5. The two ends of the inlet rings 6 are connected to a second telescopic tube 7, and the outlet of the second telescopic tube 7 is connected to both ends of the outer ring columns 2. One end of one of the outer ring columns 2 is connected to a conveying pipe 8, and the end of the conveying pipe 8 is connected to the outer side of the inner ring column 3.

[0025] In practical use, when using this device to treat the surface of copper foil, the copper foil first slides forward between two outlet frames 5. The inner ring column 3 at the previous position of the copper foil outputs liquid from the inside of the first telescopic tube 4, allowing the first telescopic tube 4 to transport the liquid to the inside of the outlet frame 5. Thus, the liquid can be sprayed onto the copper foil through the outlet frame 5 to perform pickling. At the same time, because the liquid is sprayed onto the copper foil, splashing will occur. At this time, the splashed liquid can be collected by the liquid inlet ring 6 and transported to the inside of the outer ring column 2 at that position through the second telescopic tube 7. Then, the liquid inside the outer ring column 2 can be sent to the inside of the next inner ring column 3 through the conveying pipe 8. This allows the next outlet frame 5 to first perform preliminary treatment on the surface of the copper foil with the used agent, thereby improving the utilization rate of raw materials. The pickling agent can perform preliminary pickling on the copper foil through the outlet frame 5, so that the pickling agent used can be used twice inside the outlet frame 5, reducing the loss of pickling agent.

[0026] Preferably, the outer side of one of the inner ring columns 3 is connected to the main liquid pipe 9, and the bottom of the other outer ring column 2 is connected to the drain pipe 10. The agent entering the liquid outlet frame 5 can be sprayed out to the bottom. Due to the bottom outlet of the liquid outlet frame 5, the agent can bounce back into the liquid inlet ring 6 after pickling. Thus, the liquid inlet ring 6 can collect this part of the liquid and send it to the next set of liquid outlet frames 5 for reuse, reducing the waste of resources in the surface treatment process.

[0027] In practical use, when the copper foil after preliminary treatment needs to be treated a second time in the previous liquid outlet frame 5, the pickling agent can be introduced into the inner ring column 3 through the main liquid pipe 9, so that the inner ring column 3 can send this part of the pickling liquid into the liquid outlet frame 5 for surface treatment. After the copper foil is preliminarily treated in the next liquid outlet frame 5, the liquid can also be collected through the liquid inlet ring 6, so that the liquid after two uses can flow into the outer ring column 2 and be discharged through the liquid outlet pipe 10.

[0028] Preferably, multiple limiting springs 11 are fixedly installed on the outer side of the liquid inlet ring 6, and the other end of the multiple limiting springs 11 is fixedly connected to the inner side wall of the liquid outlet frame 5.

[0029] In practical use, when the distance between the two liquid outlet frames 5 needs to be adjusted, the liquid inlet ring 6 can move synchronously with the liquid outlet frame 5. At the same time that the first telescopic tube 4 extends and retracts according to the height of the liquid outlet frame 5, the second telescopic tube 7 can also extend and retract according to the height of the liquid inlet ring 6. At this time, the limiting spring 11 on the liquid inlet ring 6 can ensure that the bottom position of the liquid inlet ring 6 is always flush with the bottom position of the liquid outlet frame 5.

[0030] Preferably, the inside of the liquid outlet frame 5 is rotatably connected to multiple guide rods 12, and a linkage gear 13 is fixedly installed on the outer side of the top of the multiple guide rods 12. A toothed chain 14 is meshed on the outer side of the linkage gear 13.

[0031] In practical use, when it is necessary to accelerate the flow of liquid inside the first telescopic tube 4 into the liquid outlet frame 5, the multiple guide rods 12 can be synchronously rotated inside the liquid outlet frame 5 by the action of the linkage gear 13 and the gear chain 14. This allows the liquid inside the first pipe to be guided into the liquid outlet frame 5 through the guide rods 12, and then sprayed out onto the surface of the copper foil from the opening of the liquid outlet frame 5.

[0032] Preferably, a motor 15 is fixedly installed inside the liquid outlet frame 5, and a transition gear 16 is fixedly installed at the top of a guide rod 12 and the output end of the motor 15.

[0033] In practical use, when the guide rod 12 needs to rotate inside the liquid outlet frame 5, the motor 15 can drive the guide rod 12 to rotate through the action of the transition gear 16.

[0034] Preferably, a connecting frame 17 is fixedly installed at both ends of the liquid outlet frame 5, and two electric telescopic rods 18 are fixedly installed at the other end of the two connecting frames 17. The fixed ends of the two electric telescopic rods 18 are fixedly connected to the inner wall of the liquid storage tank 1, and the outer side of the connecting frame 17 is slidably connected to the inner wall of the liquid storage tank 1.

[0035] In practical use, when it is necessary to adjust the distance between the two liquid outlet frames 5, the connecting frame 17 can be raised and lowered by the electric telescopic rod 18, so that the connecting frame 17 can drive the liquid outlet frame 5 to rise and fall, thereby making it easier to adjust the force exerted by the liquid sprayed from inside the liquid outlet frame 5 on the copper foil.

[0036] Preferably, a switch panel is fixedly installed on the outside of the liquid storage tank 1. A motor switch and an electric telescopic rod switch are fixedly installed on the surface of the switch panel. The motor 15 is electrically connected to an external power supply through the motor switch, and the electric telescopic rod 18 is electrically connected to an external power supply through the electric telescopic rod switch.

[0037] In practical use, the copper foil surface treatment device can be easily operated via the device switch on the switch panel.

[0038] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
