Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] In this application, the terms "upper," "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation.

[0031] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0032] Furthermore, the terms "setup" and "connection" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0033] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0034] A wet-process chain etching machine is a piece of equipment used in the semiconductor manufacturing industry, primarily for cleaning and etching silicon wafers. The cleaning step mainly uses chemical solutions to treat the silicon wafer surface, removing impurities such as particles, organic matter, metallic contaminants, and oxides. The etching step mainly uses chemical solutions (such as acid solutions and alkaline solutions) to selectively etch the silicon wafer surface to form specific circuit patterns or structures.

[0035] In related technologies, wet-process chain cleaning machines include tanks for holding silicon wafers and cleaning solutions. Typically, the bottom of the machine is equipped with a leak-proof tray and a leak detection device to ensure safer and more reliable operation. However, leaks from wet-process chain cleaning machines are usually discharged directly into a single tank without sorting, which hinders the separate collection and treatment of acidic and alkaline solutions.

[0036] In view of this, this application discloses a draining device and battery production equipment. The draining device includes a first liquid storage tank and a second liquid storage tank respectively connected to a receiving tray. A dispensing solenoid valve is connected to the receiving tray via a first pipe, to the first liquid storage tank via a second pipe, and to the second liquid storage tank via a third pipe. A detection module installed on the first pipe can detect the type of leakage in the first pipe, thereby enabling the dispensing solenoid valve to control the connection between the second pipe and the first pipe according to the type of leakage, so that the leakage in the first pipe enters the first liquid storage tank. Alternatively, the dispensing solenoid valve can control the connection between the third pipe and the first pipe, so that the leakage in the first pipe enters the second liquid storage tank. This allows the leakage from the wet chain machine receiving the receiving tray to be stored and processed separately in the first and second liquid storage tanks according to its type.

[0037] The technical solution of this application will be further described below with reference to the embodiments and accompanying drawings.

[0038] Please see Figure 1 , Figure 1 This is a schematic diagram of a drainage device disclosed in an embodiment of this application. The drainage device 100 includes a first storage tank 1, a second storage tank 2, a dispensing solenoid valve 3, and a detection module 4. The first storage tank 1 and the receiving tray 212 (e.g., for receiving leaks from the wet-process chain machine 210) are connected. Figure 3 The second liquid storage tank 2 is connected to the liquid receiving tray 212 (as shown in the diagram), and the second liquid storage tank 2 is also connected to the liquid receiving tray 212 (as shown in the diagram). Figure 3 (As shown in the diagram) is connected. The dispensing solenoid valve 3 is connected to the receiving tray 212 (as shown in the diagram) via the first pipe 31. Figure 3 (As shown in the diagram). The dispensing solenoid valve 3 is also connected to the first storage tank 1 via the second pipe 11, and the dispensing solenoid valve 3 is also connected to the second storage tank 2 via the third pipe 21. The detection module 4 is disposed in the first pipe 31, and the detection module 4 is configured to detect the type of leakage in the first pipe 31. The dispensing solenoid valve 3 is configured to control the second pipe 11 to connect with the first pipe 31 or control the third pipe 21 to connect with the first pipe 31 according to the type of leakage, so that the leakage in the first pipe 31 enters the first storage tank 1 or the second storage tank 2.

[0039] The drainage device 100 disclosed in this application can detect the type of leakage in the first pipe 31 through the detection module 4. The liquid distribution solenoid valve 3 can control the flow direction of the leakage in the first pipe 31 according to the leakage type, so that different types of leakage flow into the first storage tank 1 and the second storage tank 2 respectively. In this way, each type of leakage can be stored and processed separately, thereby improving the utilization rate of leakage.

[0040] In addition, storing different types of leaks separately makes it easier to carry out recycling, purification, or other treatment processes. For example, one type of leak can be stored directly, while another type needs to be treated before it can be stored. Separate storage allows for more efficient and precise follow-up treatment processes for each type of leak.

[0041] Furthermore, the drainage device 100 disclosed in this application can prevent chemical reactions caused by mixing different types of leaks, thus protecting the storage tank, extending its service life, and reducing equipment maintenance costs by storing different types of leaks separately.

[0042] Furthermore, the drainage device 100 disclosed in this application, through the cooperation of the detection module 4 and the liquid dispensing solenoid valve 3, enables the entire drainage process to be completed without manual intervention, saving labor costs. Moreover, the automated drainage control can ensure that the entire drainage device 100 operates more stably and accurately.

[0043] It is understood that the above-mentioned leakage types can be classified according to the acidity or alkalinity of the leakage or according to the subsequent treatment requirements of the leakage. This application will use the classification of leakage types according to acidity or alkalinity as an example for illustration.

[0044] Optionally, the detection module 4 is a pH detector. The pH detector can detect the acidity or alkalinity of the leak in the first pipe 31, and the acidic and alkaline leaks can be stored in the first storage tank 1 and the second storage tank 2 respectively. This makes the subsequent treatment process for acidic and alkaline leaks more efficient and accurate.

[0045] It is understood that the aforementioned detection module 4 is electrically connected to the dispensing solenoid valve 3, so that the dispensing solenoid valve 3 can control the second pipe 11 or the third pipe 21 to connect with the first pipe 31 based on the signal received from the detection module 4. For example, when the detection module 4 detects that the leak in the first pipe 31 is acidic, the dispensing solenoid valve 3 can control the second pipe 11 to connect with the first pipe 31, so that the acidic leak sequentially flows through the first pipe 31 and the second pipe 11 into the first storage tank 1 for storage. When the detection module 4 detects that the leak in the first pipe 31 is alkaline, the dispensing solenoid valve 3 can control the third pipe 21 to connect with the first pipe 31, so that the alkaline leak sequentially flows through the first pipe 31 and the third pipe 21 into the second storage tank 2 for storage.

[0046] It is understood that the above-mentioned liquid-dispensing solenoid valve 3 can be a direct-acting solenoid valve or a pilot-operated solenoid valve, and this embodiment does not make specific limitations on it.

[0047] It is understood that, for the drainage device 100 of this application, the aforementioned detection module 4 and dispensing solenoid valve 3 can both be electrically connected to the control module (not shown in the figure). For example, when the detection module 4 detects that the leakage in the receiving tray 212 is acidic, it can send a first signal to the control module, thereby the control module controls the dispensing solenoid valve 3 according to the first signal, so that the dispensing solenoid valve 3 controls the connection between the first pipe 31 and the second pipe 11. As another example, when the detection module 4 detects that the leakage in the receiving tray 212 is alkaline, it can send a second signal to the control module, thereby the control module controls the dispensing solenoid valve 3 according to the second signal, so that the dispensing solenoid valve 3 controls the connection between the first pipe 31 and the third pipe 21.

[0048] It is understood that, since the first storage tank 1 and the second storage tank 2 are used to store acidic and alkaline leaks respectively, taking the first storage tank 1 storing acidic leaks and the second storage tank 2 storing alkaline leaks as an example, the material of the first storage tank 1 can be polyethylene, polypropylene or fiberglass, etc., and the material of the second storage tank 2 can be stainless steel, ceramic or fiberglass, etc. This embodiment does not make specific limitations on this.

[0049] Optionally, please refer to Figure 1 The draining device 100 may include a storage tank 5, which divides the first storage tank 1 and the second storage tank 2. Dividing the two storage tanks into two separate tanks using a single storage tank 5 simplifies the structure and helps reduce the manufacturing cost of the storage device. Alternatively, in other embodiments, the first storage tank 1 and the second storage tank 2 may be separate storage tanks.

[0050] In some embodiments, please refer to Figure 1The drainage device 100 also includes a first liquid level detection module 6, which is configured to detect the liquid level of the leaking liquid in the first storage tank 1 and / or the second storage tank 2. The first liquid level detection module 6 is also configured to be electrically connected to the control panel (not shown) of the wet chain machine 210 to display the liquid level detected by the first liquid level detection module 6. By detecting the liquid level of the leaking liquid in the first storage tank 1 and / or the second storage tank 2 through the first liquid level detection module 6, and displaying the detected liquid level on the control panel of the wet chain machine 210, the liquid level in the first storage tank 1 and the second storage tank 2 can be accurately detected. This helps operators to monitor the liquid level in the first storage tank 1 and the second storage tank 2 in real time, make timely decisions, and avoid situations where excessively high liquid levels cause overflow and damage to other equipment.

[0051] It is understandable that the first liquid level detection module 6 can be set in the first liquid storage tank 1, or in the second liquid storage tank 2, or both the first liquid storage tank 1 and the second liquid storage tank 2 can be equipped with the first liquid level detection module 6.

[0052] For example, the first liquid level detection module 6 includes a first liquid level detection element 61 and a second liquid level detection element 62. The first liquid level detection element 61 and the second liquid level detection element 62 are respectively installed in the first liquid storage tank 1 and the second liquid storage tank 2. The first liquid level detection element 61 is used to detect the liquid level of leakage in the first liquid storage tank 1, and the second liquid level detection element 62 is used to detect the liquid level of leakage in the second liquid storage tank 2. By installing liquid level detection elements in both the first liquid storage tank 1 and the second liquid storage tank 2, the liquid level of leakage in each tank can be accurately monitored, thereby enabling the first liquid level detection element 61 and the second liquid level detection element 62 to protect both the first liquid storage tank 1 and the second liquid storage tank 2 respectively.

[0053] It is understood that the first liquid level detection element 61 and the second liquid level detection element 62 mentioned above can be capacitive liquid level sensors or ultrasonic liquid level sensors, etc., and this embodiment does not specifically limit them.

[0054] In some embodiments, please refer to Figure 1 The bottom of the first liquid storage tank 1 and / or the second liquid storage tank 2 is provided with a drain outlet 12, which is configured to drain any leakage from the first liquid storage tank 1 and / or the second liquid storage tank 2. By providing a drain outlet 12 at the bottom of the first liquid storage tank 1 and / or the second liquid storage tank 2, leakage in the first liquid storage tank 1 and the second liquid storage tank 2 can be drained through the drain outlet 12 when it accumulates to a certain level, thus preventing excessive accumulation of leakage in the storage tanks, which could lead to excessive liquid level overflow and damage to other equipment.

[0055] It is understandable that the drain outlet 12 can be set at the bottom of the first liquid storage tank 1, or at the bottom of the second liquid storage tank 2, or both the first liquid storage tank 1 and the second liquid storage tank 2 can be equipped with the drain outlet 12 at their bottoms.

[0056] For example, the bottom of the first liquid storage tank 1 and the second liquid storage tank 2 are respectively provided with a first drain outlet 122 and a second drain outlet 22. The first drain outlet 122 is used to drain the leakage in the first liquid storage tank 1, and the second drain outlet 22 is used to drain the leakage in the second liquid storage tank 2. By providing drain outlets at the bottom of both the first liquid storage tank 1 and the second liquid storage tank 2, drainage operations can be performed on a single liquid storage tank according to actual needs, which helps to improve the flexibility of drainage operations.

[0057] In some embodiments, please refer to Figure 2 , Figure 2 This is another structural schematic diagram of the drainage device disclosed in this application embodiment. The drainage device 100 further includes a second liquid level detection module 7, which is disposed on the side wall of the first liquid storage tank 1 and / or the second liquid storage tank 2 and near the top of the first liquid storage tank 1 and / or the second liquid storage tank 2. The second liquid level detection module 7 is configured to detect the liquid level in the first liquid storage tank 1 and / or the second liquid storage tank 2. The drain outlet 12 is provided with a first solenoid valve 121, which is configured to open the drain outlet 12 when the second liquid level detection module 7 issues a detection signal.

[0058] It is understood that, for the drainage device 100 of this application, the aforementioned second liquid level detection module 7 and first solenoid valve 121 can both be electrically connected to the control module. For example, when the second liquid level detection module 7 detects leakage in the first liquid storage tank 1 and / or the second liquid storage tank 2, it can send a signal to the control module, thereby the control module controls the first solenoid valve 121 according to the signal, so that the first solenoid valve 121 controls the drain outlet 12 to open.

[0059] This ensures that when the liquid level in the first storage tank 1 and / or the second storage tank 2 reaches the position of the second liquid level detection module 7, it can be detected by the second liquid level detection module 7. Consequently, the first solenoid valve 121 can open the drain outlet 12 to discharge any leaking liquid from the first storage tank 1 and / or the second storage tank 2. Furthermore, the cooperation between the second liquid level detection module 7 and the first solenoid valve 121 allows for automatic discharge of leaking liquid when the liquid level in the first storage tank 1 and / or the second storage tank 2 reaches a preset height. This prevents excessive accumulation of leaking liquid in the storage tanks, which could lead to overflow and damage to other equipment.

[0060] Optionally, please refer to Figure 2The second liquid level detection module 7 includes a third liquid level detection element 71 and a fourth liquid level detection element 72. The third liquid level detection element 71 is disposed on the side wall of the first liquid storage tank 1 and near the top of the first liquid storage tank 1, and is used to detect the liquid level in the first liquid storage tank 1. The fourth liquid level detection element 72 is disposed on the side wall of the second liquid storage tank 2 and near the top of the second liquid storage tank 2, and is used to detect the liquid level in the second liquid storage tank 2. The first drain outlet 122 is provided with a first solenoid valve 121, which is configured to open the first drain outlet 122 when the third liquid level detection element 71 sends a detection signal. The second drain outlet 22 is provided with a second solenoid valve 221, which is configured to open the second drain outlet 22 when the fourth liquid level detection element 72 sends a detection signal.

[0061] It is understood that, for the drainage device 100 of this application, the aforementioned third liquid level detection element 71, fourth liquid level detection element 72, first solenoid valve 121, and second solenoid valve 221 can all be electrically connected to the control module. For example, when the third liquid level detection element 71 detects leakage in the first storage tank 1, it can send a first signal to the control module, thereby the control module controls the first solenoid valve 121 according to the first signal, causing the first solenoid valve 121 to control the opening of the first drain outlet 122. As another example, when the fourth liquid level detection element 72 detects leakage in the second storage tank 2, it can send a second signal to the control module, thereby the control module controls the second solenoid valve 221 according to the second signal, causing the second solenoid valve 221 to control the opening of the second drain outlet 22.

[0062] By having a third liquid level detection element 71 and a first solenoid valve 121 in the first liquid storage tank 1, and a fourth liquid level detection element 72 and a second solenoid valve 221 in the second liquid storage tank 2, the leakage can be automatically discharged when the liquid level in the first liquid storage tank 1 and the second liquid storage tank 2 reaches a preset height. This can prevent the accumulation of excessive leakage in the liquid storage tank, which could lead to excessive liquid level and overflow, and damage to other equipment.

[0063] It is understood that the third liquid level detection element 71 and the fourth liquid level detection element 72 may be of the same type as the first liquid level detection element 61, or may be a resistive liquid level sensor, etc. This embodiment does not make specific limitations on this.

[0064] It is understood that the first solenoid valve 121 and the second solenoid valve 221 mentioned above can be of the same type as the liquid-dispensing solenoid valve 3 mentioned above, and this embodiment will not elaborate on this further.

[0065] Please see Figure 3 , Figure 3This is a schematic diagram of the battery production equipment disclosed in an embodiment of this application. In a second aspect, this application also discloses a battery production equipment 200, including a wet-process chain machine 210 and a draining device 100 as described in the first aspect. The wet-process chain machine 210 includes a machine body 211 and a drain tray 212. The drain tray 212 is spaced below the machine body 211 and configured to receive leakage from the machine body 211. By providing the drain tray 212 below the machine body 211, leakage from the machine body 211 can be received by the drain tray 212, thereby preventing leakage from flowing onto other equipment and causing damage.

[0066] The drainage device 100 in this embodiment may have the same structure as any of the drainage devices 100 in the above embodiments and may bring the same or similar beneficial effects. For details, please refer to the description in the above embodiments. This embodiment will not be repeated here.

[0067] In some embodiments, please refer to Figure 3 The battery production equipment 200 also includes a control module (not shown in the figure), a sensor 220, and a water pump 230. The sensor 220 is disposed on the liquid receiving tray 212 and is configured to sense whether there is leakage in the liquid receiving tray 212. The water pump 230 is disposed on the first pipe 31 and is used to draw the leakage liquid to the first pipe 31 when the sensor 220 senses leakage in the liquid receiving tray 212.

[0068] It is understood that, for the battery production equipment of this application, both the aforementioned sensor 220 and water pump 230 can be electrically connected to the control module. For example, when the sensor 220 detects leakage in the receiving tray 212, it can send a signal to the control module, thereby the control module controls the water pump 230 according to the signal, so that the water pump 230 pumps the leakage in the receiving tray 212 to the first pipe 31.

[0069] On the one hand, the sensor 220 can detect whether there is any leakage in the drip tray 212 in a timely manner. Once a leakage occurs, it can be detected quickly, preventing the leakage from accumulating in the drip tray 212 and flowing into the surrounding environment, thereby protecting the surrounding equipment from leakage corrosion. On the other hand, through the cooperation between the sensor 220 and the water pump 230, the water pump 230 can be automatically triggered to work, promptly pumping the leakage in the drip tray 212 into the first pipe 31, thus eliminating the need for continuous manual monitoring of the leakage in the drip tray 212.

[0070] It is understood that the aforementioned sensing element 220 may be a capacitive liquid level sensor or a float liquid level sensor, etc., and this embodiment does not specifically limit it.

[0071] Optionally, please refer to Figure 3 The bottom of the drip tray 212 is equipped with a suction port 212a, to which the first pipe 31 is connected. A water pump 230 is connected to the end where the first pipe 31 and the suction port 212a meet. Due to gravity, the leaking liquid in the drip tray 212 will accumulate at the bottom. The suction port 212a allows the leaking liquid to flow out more effectively. Furthermore, the water pump 230, located at the end of the first pipe 31 connected to the suction port 212a, can quickly extract the leaking liquid from the drip tray 212, preventing excessive accumulation of liquid in the drip tray 212.

[0072] In some embodiments, please refer to Figure 3 The projection of the machine body 211 onto the liquid receiving tray 212 is located within the surface area of ​​the liquid receiving tray 212. This allows all leaks from the machine to be collected through the liquid receiving tray 212, thus preventing any uncollected leaks from damaging other equipment.

[0073] The following is a brief description of the drainage process using the drainage device 100 of this application:

[0074] When leakage occurs in the wet chain conveyor, the leakage flows into the receiving tray 212. The sensor 220 detects the leakage in the receiving tray 212 and sends a signal to the control module. Based on this signal, the control module controls the water pump 230, which pumps the leakage from the receiving tray 212 to the first pipe 31. The detection module 4 detects the type of leakage in the first pipe 31. When the detection module 4 detects that the leakage in the receiving tray 212 is acidic, it sends a first signal to the control module. Based on this first signal, the control module controls the dispensing solenoid valve 3, which connects the first pipe 31 to the second pipe 11, discharging the acidic leakage into the first storage tank 1 for storage.

[0075] When the detection module 4 detects that the leaked liquid in the receiving tray 212 is alkaline, it sends a second signal to the control module. The control module then controls the dispensing solenoid valve 3 based on this second signal, causing the dispensing solenoid valve 3 to connect the first pipe 31 and the third pipe 21, discharging the alkaline leaked liquid into the second storage tank 2 for storage. The first liquid level detection module 6 can detect the liquid level in the first storage tank 1 and / or the second storage tank 2, and display the result in real time on the control panel of the wet chain conveyor 210.

[0076] When the liquid level in the first storage tank 1 rises to the level detected by the third liquid level detector 71, the third liquid level detector 71 sends a signal to the control module, and the control module controls the first solenoid valve 121 according to the signal, so that the first solenoid valve 121 controls the first drain outlet 122 to open, thereby draining the acidic liquid in the first storage tank 1.
