[0027] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the features in the following embodiments can be combined with each other.

[0028] Please refer to Figure 1 This utility model embodiment provides a battery production line (not shown) for producing new energy batteries. It can effectively remove the solution adhering to the basket 130 and silicon wafers, avoiding contamination, ensuring product quality, and preventing solution waste, thus saving process costs.

[0029] It should be noted that the battery production line includes a wet processing unit 100 and processing equipment (not shown in the figure). The wet processing unit 100 and the processing equipment are arranged sequentially. The wet processing unit 100 is used to clean, texturize, and polish silicon wafers using wet processes, while the processing equipment is used to perform deposition, coating, and other processing on the silicon wafers to produce new energy batteries.

[0030] The wet process equipment 100 includes a robotic arm 110, a mounting frame 120, a basket 130, a purging mechanism 140, and a solution tank 150. The mounting frame 120 is connected to the free end of the robotic arm 110 and is connected to the basket 130, which is used to load silicon wafers. The robotic arm 110 can move the basket 130 and the silicon wafers loaded in it via the mounting frame 120. The solution tank 150 is used to hold a solution. The robotic arm 110 uses the basket 130 to guide the silicon wafers into the solution tank 150 and into contact with the solution, so that the solution reacts with the silicon wafers or cleans the wafers, completing the wet process. Specifically, the purging mechanism 140 is mounted on the mounting frame 120 and positioned above the basket 130. The purging mechanism 140 is used to purge the basket 130 and the silicon wafer when the robotic arm 110 retracts the silicon wafer from the solution tank 150 via the basket 130. This allows the solution adhering to the basket 130 and the silicon wafer to fall back into the solution tank 150 under the influence of wind and gravity, thus replenishing the solution. In this way, the wet processing equipment 100 can effectively remove the solution adhering to the basket 130 and the silicon wafer after the wet process, preventing contamination as the solution enters the next process with the basket 130 and the silicon wafer, ensuring product quality, avoiding solution waste, and saving process costs.

[0031] In this embodiment, there are multiple solution tanks 150 arranged side by side. Different solution tanks 150 contain solutions of different compositions to facilitate different types of wet processing steps. Specifically, the robotic arm 110 moves the basket 130 and the silicon wafers loaded within it via the mounting frame 120, allowing the basket 130 and silicon wafers to sequentially enter multiple solution tanks 150 and come into contact with various solutions, thereby performing multiple wet processing steps on the silicon wafers and improving production efficiency. Furthermore, each time the robotic arm 110 retracts the silicon wafer from the solution tank 150 via the basket 130, the blowing mechanism 140 blows the basket 130 and silicon wafer to remove any solution adhering to them, reducing or preventing the solution from entering the next wet processing solution tank 150 along with the basket 130 and silicon wafer.

[0032] Please refer to the reference. Figure 2 and Figure 3 The purging mechanism 140 includes an air pump 141, an air pipe 142, and an air nozzle 143. One end of the air pipe 142 is connected to the air pump 141, and the other end is connected to the air nozzle 143. The air nozzle 143 is mounted on the mounting bracket 120. The air pump 141 is used to generate negative pressure to draw outside air into the air pipe 142 and through the air pipe 142 to the air nozzle 143. The air nozzle 143 is used to spray air towards the basket 130 and the silicon wafer to achieve the purging function.

[0033] Furthermore, the purging mechanism 140 also includes a translation component 144. The translation component 144 is connected to the air nozzle 143, which is slidably engaged with the mounting bracket 120. The translation component 144 is used to drive the air nozzle 143 to slide relative to the mounting bracket 120, thereby significantly increasing the jetting area of ​​the air nozzle 143, improving the solution removal efficiency, and ensuring the solution removal effect.

[0034] The translation assembly 144 includes a drive member 1441, a lead screw 1442, and a nut seat 1443. The drive member 1441 is mounted on the mounting bracket 120 and connected to the lead screw 1442. The nut seat 1443 is sleeved on the lead screw 1442 and threadedly engaged with it, and connected to the air nozzle 143. Specifically, the drive member 1441 drives the lead screw 1442 to rotate, thereby causing the nut seat 1443 to translate axially along the lead screw 1442 through the threaded engagement between the lead screw 1442 and the nut seat 1443. This, in turn, causes the air nozzle 143 to move axially along the lead screw 1442, increasing the air jet area of ​​the air nozzle 143.

[0035] Specifically, there are multiple translation components 144 and multiple air nozzles 143. The vent pipe 142 includes a main pipe 1421 and multiple branch pipes 1422. One end of the main pipe 1421 is connected to the air pump 141, and the other end is connected to multiple branch pipes 1422. Each branch pipe 1422 is connected to one air nozzle 143, and each air nozzle 143 is connected to one translation component 144. The multiple translation components 144 are arranged in parallel and spaced apart. Specifically, multiple lead screws 1442 in the multiple translation components 144 are arranged in parallel and spaced apart. Each air nozzle 143 can move along the axial direction of one lead screw 1442. The multiple air nozzles 143 work together to further increase the air jet area, so that the basket 130 and the silicon wafer can be thoroughly purged, improving the solution removal effect.

[0036] The mounting frame 120 includes a top plate 121, a first side plate 122, and a second side plate 123. The first side plate 122 and the second side plate 123 are disposed opposite to each other at both ends of the top plate 121 and are both connected to the top plate 121. The top plate 121 is connected to a robotic arm 110, and the robotic arm 110 can synchronously drive the first side plate 122 and the second side plate 123 to move through the top plate 121. Specifically, a blowing mechanism 140 is mounted on the top plate 121, and a basket 130 is connected between the first side plate 122 and the second side plate 123, so that the blowing mechanism 140 is positioned above the basket 130, which facilitates the blowing mechanism 140 to blow downwards the basket 130 and the silicon wafers loaded in the basket 130, thereby blowing the solution adhering to the basket 130 and the silicon wafers into the solution tank 150.

[0037] Furthermore, the first side plate 122 is provided with a first hook 1221, and the second side plate 123 is provided with a second hook 1231; one side of the flower basket 130 is provided with a first hanging ring 131, and the other side is provided with a second hanging ring 132; the first hanging ring 131 is hooked to the first hook 1221, and the second hanging ring 132 is hooked to the second hook 1231, so as to hang the flower basket 130 between the first side plate 122 and the second side plate 123, which facilitates the installation and removal of the flower basket 130. The first side plate 122 and the second side plate 123 work together to limit the flower basket 130, prevent the flower basket 130 from shaking or tilting, and improve the stability of the flower basket 130 during transportation.

[0038] Please refer to Figure 4The solution tank 150 includes a tank body 151, a first tank cover 152, and a second tank cover 153. The first tank cover 152 and the second tank cover 153 are disposed opposite each other on both sides of the tank body 151 and are hinged to the tank body 151. The tank body 151 is used to hold the solution. Specifically, both the first tank cover 152 and the second tank cover 153 are rotatable relative to the tank body 151, and are used together to open or close the tank body 151. When the first tank cover 152 and the second tank cover 153 open the tank body 151 together, the robotic arm 110 can use the basket 130 to pull the silicon wafer into the tank body 151; when the first tank cover 152 and the second tank cover 153 close the tank body 151 together, it can prevent external impurities from entering the tank body 151 and contaminating the solution.

[0039] Please continue to refer to Figure 1 It should be noted that there are multiple mounting frames 120, baskets 130, and purging mechanisms 140. Multiple mounting frames 120 are arranged side by side, each basket 130 is connected to one mounting frame 120, and each purging mechanism 140 is mounted on one mounting frame 120. The robotic arm 110 can simultaneously drive multiple baskets 130 into the solution tank 150 through multiple mounting frames 120. Each purging mechanism 140 can purge one basket 130 and the silicon wafer loaded in the basket 130, thereby improving the efficiency of the wet process.

[0040] In this embodiment, there are two of each of the mounting bracket 120, flower basket 130, and blowing mechanism 140, but it is not limited to this. In other embodiments, there may be three or four of each of the mounting bracket 120, flower basket 130, and blowing mechanism 140. The number of each of the mounting bracket 120, flower basket 130, and blowing mechanism 140 is not specifically limited.

[0041] The wet processing equipment 100 provided in this embodiment of the utility model has a mounting frame 120 connected to the free end of a robotic arm 110. The mounting frame 120 is connected to a basket 130, which is used to load silicon wafers. A solution tank 150 is used to hold solution. The robotic arm 110 is used to drive the silicon wafers into the solution tank 150 and into contact with the solution through the basket 130. A purging mechanism 140 is mounted on the mounting frame 120 and positioned above the basket 130. The purging mechanism 140 is used to purge the basket 130 and the silicon wafers when the robotic arm 110 drives the silicon wafers out of the solution tank 150 through the basket 130, so that the solution adhering to the basket 130 and the silicon wafers falls back into the solution tank 150. Compared with existing technologies, the wet processing equipment 100 provided by this utility model, due to the use of a basket 130 connected to the mounting frame 120 and a blowing mechanism 140 installed on the mounting frame 120 and positioned above the basket 130, can effectively remove the solution adhering to the basket 130 and the silicon wafer, avoiding contamination, ensuring product quality, and preventing solution waste, thus saving process costs. This results in high-quality products and high economic benefits for the battery production line.
