Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production and manufacturing, in particular to one-step wet chemical plating equipment for composite materials. Background Art

[0002] Currently, in the production of aluminum batteries, copper foil is usually used as a component of the negative electrode because of its strong conductivity, soft texture, and non-reaction with lithium.

[0003] Chemical plating (also known as chemical plating) is a new type of surface treatment technology. This technology has attracted increasing attention for its advantages of energy saving and environmental protection. Among them, the one-step wet process is a chemical plating method for producing composite copper foil. It mainly immerses the substrate in a solution containing polymers and other additives in a wet process, and then treats it under specific conditions to deposit copper on the surface of the substrate and combine with the substrate to form a strong composite structure, thereby obtaining a composite copper foil. This method can also be used to produce other composite materials with specific properties and uses.

[0004] However, in the actual production process, it was found that the adaptability of some substrates was poor, resulting in poor tightness when copper was combined with them, and the metal layer was loose. In addition, the one-step wet process equipment in the prior art usually only performs a single deposition. Although this method can greatly shorten the processing time, the deposition rate is difficult to control, and a single deposition can easily lead to uneven thickness of the metal layer, affecting the quality of the finished product. In addition, the deposition liquid needs to undergo pre-treatment processes such as filtration and stirring before deposition. Such processes are usually performed on other equipment, so a certain transfer time is required, which reduces the processing efficiency. Utility Model Content

After the coating on the other side is completed, it is immediately sent to the drying device for drying. Dry to solidify the coatings on both sides; multiple deposition tanks in the deposition device are arranged in sequence, and each deposition tank is provided with a deposition liquid.

[0068] Please refer to Figures 8 to 10 The sedimentation tank 41 is provided with a circulation component 47, and the circulation component 47 includes a circulation power part 471 and a circulation pipeline 472. The circulation power part 471 is installed on the outer surface of the sedimentation tank 41, and the circulation pipeline 472 is connected to the interior of the sedimentation tank 41. The circulation power part 471 is connected to the circulation pipeline 472.

[0069] The circulation pipeline 472 is connected to the interior of the deposition tank 41. The circulation power part 471 can suck the deposition liquid in the deposition tank 41 into the circulation pipeline 472 and then send it back to the deposition tank 41, so as to realize the circulation flow of the deposition liquid between the circulation pipeline 472 and the deposition tank 41, effectively increase the fluidity of the deposition liquid, make the components in the deposition liquid evenly distributed, avoid local concentration being too high or too low, and make the thickness of the metal layer obtained by deposition more uniform.

[0070] Specifically, Fig. 9 For example, in this embodiment, the circulating power parts 471 are arranged at intervals on the two side surfaces of the sedimentation tank 41, with two arranged on each side, and each circulating power part 471 is connected to a circulation pipeline 472. By arranging the circulating power parts 471 and the circulation pipeline 472 at intervals, the sedimentation liquid can be drawn out from different positions of the sedimentation tank 41 for circulation, avoiding the local concentration of the sedimentation liquid being too high or too low, and making the sedimentation liquid more uniform.

[0071] Please refer to Fig.10 In another embodiment, three circulation power parts 471 are arranged on the two side surfaces of the sedimentation tank 41 at intervals, wherein the circulation power parts 471 on both sides are connected to a circulation pipeline 472, and the circulation power part 471 in the middle is connected to two circulation pipelines 472, and the two circulation pipelines 472 are respectively connected to the circulation pipelines 472 on both sides. During specific operation, the circulation power part 471 in the middle can extract the sedimentation liquid and send it to the circulation pipelines 472 on both sides through the two connected circulation pipelines 472, and the circulation power parts 471 and circulation pipelines 472 on both sides normally extract the sedimentation liquid and send it back to the sedimentation tank 41. By setting in this way, the mixing effect of the sedimentation liquid at each position in the sedimentation tank 41 can be enhanced, the formation of local concentration gradients can be effectively prevented, and the sedimentation liquid can be made more uniform.

The auxiliary tank 48 is connected to the interior of the sedimentation tank 41 through a pipeline structure. A plurality of filters 481 and a power pump 482 are installed on the auxiliary tank 48.

[0073] The cavity inside the sub-tank 48 for storing the sedimentation liquid is connected to the inside of the sedimentation tank 41 through a pipeline structure, which is convenient for sending the sedimentation liquid into the sedimentation tank 41, or for directing the sedimentation liquid in the sedimentation tank 41 to the sub-tank 48. The sub-tank 48 is installed with a plurality of filters 481 and a power pump 482 according to the components and needs of the sedimentation liquid in each sedimentation tank 41. The filter 481 is used to filter the sedimentation liquid when it enters the sub-tank 48, and the power pump 482 can provide power to help stir the sedimentation liquid, so as to promote its rapid and uniform mixing.

[0074] It should be noted that the auxiliary tank 48 and the sedimentation tank 41 are not necessarily arranged one-to-one. Depending on the components of the sedimentation liquid in the sedimentation tank 41, there may be a situation where one auxiliary tank 48 corresponds to multiple sedimentation tanks 41, such as Figure 4 and Figure 8 As shown in , it is set according to actual needs during specific implementation; at the same time, the number of filters 481 and power pumps 482 is also allocated and set according to actual needs.

[0075] Please refer to Figure 1 The drying device 3 includes a plurality of ovens 31, which are arranged in sequence along the conveying direction of the coiled material. The coiled material after coating is baked by the plurality of ovens 31 to ensure that the coating is completely cured.

[0076] Please refer to Figure 4 , Figure 7 and Figure 8 The deposition device 4 also includes a transfer mechanism 49, which is arranged on one side of the deposition device 4 close to the drying device 3 and is used to guide the coil sent out of the oven 31. The transfer mechanism 49 is provided with a transfer roller 491 and a transfer drive 492. The transfer drive 492 is connected to one end of the transfer roller 491 and is used to drive the transfer roller 491 to rotate, thereby driving the coil to move along the conveying path.

[0077] Please refer to Figure 2 and Figure 3 The unwinding base 11 and the coating base 21 are both provided with an adjustment component 18, and the adjustment component 18 includes an adjustment block 181, an adjustment rod 182 and an adjustment knob 183.

One end of the adjustment rod 182 is connected to the adjustment knob 183, and the other end is connected to the unwinding bracket 12 or the coating bracket 22.

[0078] In this embodiment, the adjustment block 181 is fixedly installed on the unwinding base 11 or the coating base 21, and the adjustment knob 183 can be rotated to drive the adjustment rod 182 to rotate. Since the adjustment rod 182 is threadedly connected to the adjustment block 181, the adjustment rod 182 can move in the axial direction when it rotates, thereby driving the unwinding bracket 12 or the coating bracket 22 to move, thereby realizing the position adjustment of the unwinding bracket 12 or the coating bracket 22. The structure is simple and the operation is easy.
