Description

Technical Field

[0001] This application relates to the field of semiconductor manufacturing technology, and particularly to a cleaning tank and a solar cell cleaning device. Background Art

[0002] In the production process of solar cells, a solar cell cleaning device is required to clean the solar cells. The cleaning process is completed in the cleaning tank of the solar cell cleaning device. When putting the solar cells into the cleaning tank, the lid of the cleaning tank needs to be opened, and then the solar cells are cleaned with the lid closed. Therefore, the lid of the cleaning tank needs to be opened and closed frequently.

[0003] Since the cleaning solution used to clean the solar cells in the cleaning tank has the characteristics of strong acid or strong base, in the related art, there is a solution using a flipping mechanism to automatically open and close the lid. However, the current flipping mechanism is mainly used to realize the automatic opening and closing of the lid, and cannot ensure that the lid is opened at the expected opening angle, resulting in the situation that the basket device carrying the solar cells is likely to collide with the lid with an insufficient opening angle, or the overly opened lid collides with the lid of the adjacent cleaning tank, thus causing damage to the lid, the cleaning basket or the solar cells. Summary of the Utility Model

The tank body has a tank opening; the first edge of the lid is rotatably connected to the tank body, and the lid can open or close the tank opening; the opening and closing mechanism includes a telescopic traction member and a sliding member movably connected to the traction member. The fixed end of the traction member is movably connected to the lid, and the sliding member is slidably disposed on the tank body and can reciprocate between a first position and a second position; wherein, when the sliding member reciprocates between the first position and the second position, the sliding member pulls the traction member to drive the lid to flip relative to the tank body to open or close the tank opening.

[0006] In a possible implementation manner of the first aspect, the traction member is a rigid traction member. When the sliding member is in the first position, the traction member supports the lid to keep it in the state of opening the tank opening.

[0009] In a possible implementation of the first aspect, the fixed end of the traction member is located in the corner area of the cover body, and the corner area is far from the first edge.

[0010] In a possible implementation of the first aspect, the number of the opening and closing mechanisms is two. The two opening and closing mechanisms are used to open or close a cover body. When the sliders of each opening and closing mechanism approach the first position from their respective second positions, the two sliders approach each other.

[0011] In a possible implementation of the first aspect, anti-collision blocks are further arranged on the slideway. When the two sliders are respectively in their first positions, they are located on both sides of the anti-collision blocks; two stop members are further arranged on the slideway, and the stop members are located at both ends of the slideway.

[0012] In a possible implementation of the first aspect, a plurality of sensors are further arranged on the tank body.

[0013] In a possible implementation of the first aspect, the cleaning tank further includes: a driving component, which is arranged on the tank body, and the driving component is used to drive the slider to move along the slideway.

[0014] The second aspect of the present application further provides a battery wafer cleaning device, which includes the cleaning tank in any possible implementation of the first aspect of the present application, and a plurality of cleaning tanks are arranged at linear intervals.

[0016] The cleaning tank provided by the embodiment of the present application controls the cover body to flip relative to the tank body to open and close the tank opening through the opening and closing mechanism, and can open the cover body to a preset angle, so that the cover body will neither interfere with the entry and exit of the cleaning basket due to improper opening and closing, nor collide with the cover bodies of adjacent cleaning tanks due to excessive opening, thereby ensuring the operation safety of the cleaning tank and improving the cleaning efficiency and yield of the battery wafers.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0027] In the present application, terms such as "upper", "lower", "left", "right", "front", "rear", "top", "bottom", "inner", "outer", "vertical", "horizontal", "lateral", "longitudinal", etc. indicate the orientation or positional relationship based on the orientation or positional relationship of the accompanying drawings. These terms are mainly used to better describe the present application and its embodiments, and are not used to limit that the indicated devices, elements or components must have a specific orientation, or be constructed and operated in a specific orientation.

[0028] Moreover, in addition to being used to indicate orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this application can be understood according to the specific circumstances.

[0029] In addition, the terms "install", "set", "provided with", "connect", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there is internal communication between two devices, components or parts. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0030] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, components or parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, components or parts. Unless otherwise specified, the meaning of "a plurality of" is two or more.

[0031] In the production process of solar cells, a cell cleaning device is required to clean the cells. The cell cleaning device usually consists of a plurality of cleaning tanks, and different cleaning processes are performed in each cleaning tank, such as chemical cleaning, rinsing, drying, etc. These cleaning tanks are usually arranged side by side at intervals to form a continuous cleaning line. A track is provided above the plurality of cleaning tanks, and a manipulator for clamping the cleaning basket can move smoothly on the track, so that the cleaning basket carrying the cells can flow between the cleaning tanks, realizing an automated cleaning process for the cells.

[0032] Before the manipulator places the cleaning basket carrying the cells in the cleaning tank, the cover of the cleaning tank needs to be opened first. If the flipping angle of the cover is not enough, it will cause the cleaning basket to collide with the cover. If the flipping angle of the cover is too large, it may cause the covers of two adjacent cleaning tanks to collide and deform. After the cover is damaged, the cleaning basket may not be able to enter or exit the cleaning tank, thus affecting the cleaning efficiency of the entire cleaning line.

[0033] Based on this, the present application provides a cleaning tank and a cell cleaning device, by configuring an opening and closing mechanism on the cleaning tank to accurately control the flipping angle of the cover, preventing the cover from being opened incompletely and overly opened, thereby avoiding the phenomenon of damage to the cleaning tank or adjacent covers, and thus improving the cleaning efficiency of the cell cleaning device.

[0034] Figures 1 to 3The structural schematic diagram of the cleaning tank 01 provided by the embodiment of the present application is shown. The tank body 10 includes a tank body 10, a cover body 20 and at least one opening and closing mechanism 30. The tank body 10 has a tank opening 101; the first edge 201 of the cover body 20 is rotatably connected to the tank body 10, and the cover body 20 can open or close the tank opening 101; the opening and closing mechanism 30 includes a telescopic traction member 301 and a sliding member 302 movably connected to the traction member 301. The fixed end of the traction member 301 is movably connected to the cover body 20, and the sliding member 302 is slidably disposed on the tank body 10 and can reciprocate between a first position and a second position; wherein, when the sliding member 302 reciprocates between the first position and the second position, the sliding member 302 pulls the traction member 301 to drive the cover body 20 to flip relative to the tank body 10 to open or close the tank opening 101.

[0035] In this embodiment, the tank body 10 has a cleaning cavity for accommodating a cleaning solution. The cleaning solution can clean the battery wafers placed in the tank body 10. The tank opening 101 of the tank body 10 communicates with the cleaning cavity. The tank opening 101 is used for injecting the cleaning solution into the cleaning cavity and for the cleaning basket to enter and exit. The tank body 10 is generally made of corrosion-resistant and high-temperature-resistant materials to adapt to different types of cleaning solutions and different cleaning temperature conditions.

[0036] In order to prevent the strongly corrosive cleaning solution from splashing out of the cleaning tank 01 during the process of cleaning the battery wafers, a flip-up cover body 20 needs to be provided on the tank body 10 to open and close the tank opening 101 of the tank body 10. The cover body 20 has a first edge 201. The first edge 201 is connected to the tank opening 101 of the tank body 10, and the first edge 201 of the cover body 20 is movably connected to the tank body 10 through a rotary coupling. Optionally, the first edge 201 can be the edge of the long side of the cover body 20.

[0037] As Figure 1 and Figure 2 shown, the cleaning tank 01 is at least configured with one opening and closing mechanism 30. The opening and closing mechanism 30 is used to control the flipping of the cover body 20 to open or close the tank opening 101, and can also accurately control the flipping angle of the cover body 20. The opening and closing mechanism 30 includes a telescopic traction member 301 and a sliding member 302 movably connected to the traction member 301. The sliding member 302 is located at the telescopic end of the telescopic traction member 301. The fixed end of the traction member 301 is positioned on the cover body 20 but can move relative to the cover body 20.

[0038] The sliding member 302 is slidably disposed in the groove body 10. There are two limit positions on the movement path of the sliding member 302, namely the first position and the second position, and the sliding member 302 can reciprocate between the first position and the second position. The first position and the second position can be formed on the groove body 10 at intervals along the extending direction parallel to the first edge 201. When the sliding member 302 is in the first position, the cover body 20 is in a state where the notch 101 is opened and the cover body 20 is at a preset angle relative to the notch 101. When the sliding member 302 is in the second position, the cover body 20 can be in a state of closing the notch 101.

[0039] When the cover body 20 is in the state of closing the notch 101 and it is necessary to open the cover, the sliding member 302 at the second position moves towards the first position. As the sliding member 302 moves, the telescopic end of the traction member 301 is pulled out. Since the fixed end of the traction member 301 is rotatably disposed on the cover body 20, during the movement of the sliding member 302 towards the first position, the fixed end of the traction member 301 rotates with the sliding member 302, and the cover body 20 is pulled by the traction member 301 to gradually flip relative to the groove body 10 along the first edge 201. As Figure 3 shown, when the sliding member 302 moves to the first position, the flipping angle of the cover body 20 reaches the preset angle, thereby realizing the precise control of the flipping angle of the cover body 20 by the opening and closing mechanism 30. The cover body 20 at the preset angle neither interferes with the entry and exit of the cleaning basket nor collides with the cover body 20 of the adjacent cleaning tank 01, thus ensuring the use safety of the cleaning tank 01.

[0040] It can be understood that there is a corresponding relationship between the movement position of the sliding member 302 and the flipping angle of the cover body 20. By reasonably designing the fixed position of the traction member 301 and the first position of the sliding member 302, it can be ensured that when the sliding member 302 moves to the first position, the flipping angle of the cover body 20 is the preset angle. Optionally, the above preset angle can be selected between 100° and 105°, for example, the preset angle can be 100°, 102°, 104° or 105°.

[0041] When it is necessary to close the notch 101 by the cover body 20, the sliding member 302 moves towards the second position and drives the telescopic end of the traction member 301 to retract, and the traction member 301 drives the cover body 20 to flip towards the groove body 10, so that the cover body 20 is re-fastened on the notch 101.

[0042] It should be noted that in order to ensure the normal operation of the opening and closing mechanism 30, the friction force for the sliding member 302 to drive the traction member 301 to expand and contract needs to be large enough to overcome the friction force for the cover body 20 to flip relative to the groove body 10 and the gravity of the cover body 20. In this way, the traction member 301 can smoothly pull the cover body 20 and make the cover body 20 open smoothly.

[0043] Optionally, two cover bodies 20 can be arranged side by side on the tank body 10, so that the cleaning tank 01 can be configured with at least two opening and closing mechanisms 30, and each opening and closing mechanism 30 is used to control one cover body 20 to flip to open or close the tank body 10.

[0044] Thus, for the cleaning tank 01 provided by the embodiment of the present application, by setting the opening and closing mechanism 30, not only can the cover body 20 be flipped relative to the tank body 10 to open or close the tank opening 101, but the opening and closing mechanism 30 can also open the cover body 20 to a preset angle, so that the cover body 20 will neither interfere with the entry and exit of the cleaning basket due to improper opening and closing, nor collide with the cover body 20 of the adjacent cleaning tank 01 due to excessive opening, thereby ensuring the operation safety of the cleaning tank 01 and improving the cleaning efficiency and yield of the battery wafers.

[0045] In order to be able to continue to maintain this state after the cover body 20 is flipped to the preset angle, in some embodiments, the traction member 301 is a rigid traction member. Optionally, the traction member 301 can be a telescopic rod.

[0046] Since the fixed end of the traction member 301 is positioned on the cover body 20, and the sliding member 302 no longer moves after sliding to the first position. Therefore, when the cover body 20 is flipped to the preset angle, the telescopic length of the traction member 301 is fixed. Since the traction member 301 is rigid, the traction member 301 can provide a supporting force for the cover body 20 flipped to the preset angle, so that the cover body 20 is kept in an open state at a preset angle with respect to the tank body 10.

[0047] In addition, during the long-term use of the cover body 20, the high temperature for cleaning the battery wafers and the gas formed by the evaporation of the cleaning solution will cause the cover body 20 to deform, and the deformed cover body 20 may not be able to completely close at the tank opening 101 of the tank body 10. Since the traction member 301 is rigid, when the sliding member 302 slides from the first position to the second position, the traction member 301 can also exert a certain degree of pressure on the deformed cover body 20, so that the cover body 20 is tightly covered on the tank body 10.

[0048] Thus, the opening and closing mechanism 30 can not only accurately control the flipping angle of the cover body 20, but the traction member 301 in the opening and closing mechanism 30 can also support the cover body 20 in the open state. When it is necessary to close the tank opening 101, the traction member 301 can also perform a certain degree of shaping on the slightly deformed cover body 20 to overcome the deformation, so as to reduce the occurrence of the cleaning solution splashing outside during the cleaning process of the battery wafers.

[0049] In some embodiments, such as Figure 1 and Figure 2As shown, the cleaning tank 01 further includes a slideway 40. The slideway 40 is located at the notch 101 of the tank body 10 and is disposed close to the first edge 201. The slideway 40 is disposed close to the first edge 201, so that the pulling force generated by the sliding member 302 during the sliding process can be more effectively transmitted to the cover body 20, thereby reducing energy loss and improving transmission efficiency. Optionally, the slideway 40 can be a slide rail or a chute.

[0050] The sliding member 302 is slidably disposed on the slideway 40, that is, the slideway 40 is used to enable the sliding member 302 to slide relative to the tank body 10. Since the slideway 40 defines the movement path of the sliding member 302, the above-mentioned first position and second position are located on the slideway 40.

[0051] Further, the slideway 40 can be parallel to the extending direction of the first edge 201, so that the movement track of the sliding member 302 matches the flipping track of the cover body 20. When the sliding member 302 slides in the slideway 40, it can effectively and smoothly pull the traction member 301, thereby driving the cover body 20 to flip at a preset angle to open or close the notch 101, improving the efficiency and reliability of opening and closing the cover body 20.

[0052] In some embodiments, as Figure 1 and Figure 2 shown, the cover body 20 further includes a second edge 202 perpendicular to the first edge 201. The fixed end of the traction member 301 is close to the second edge 202, and the sliding member 302 in the first position is farther from the second edge 202 than the fixed end of the traction member 301.

[0053] As described above, the first edge 201 is the edge of the long side of the cover body 20, so the second edge 202 perpendicular to the first edge 201 is the edge of the short side. By disposing the fixed end of the traction member 301 close to the second edge 202 and setting the first position at a position far from the second edge 202, a larger force arm can be formed when the traction member 301 is stretched by the sliding member 302, so that the cover body 20 can be flipped to the preset angle more smoothly and stably, reducing the situation of shaking or instability of the cover body 20 during the flipping process due to insufficient pulling torque of the traction member 301.

[0054] On the slideway 40, the second position can also be located at the end of the slideway 40 and be relatively close to the second edge 202, that is, the sliding member 302 moves from the second position close to the second edge 202 to the first position far from the second edge 202. This is equivalent to the sliding member 302 needing to pass through a longer path when pulling the traction member 301 to elongate, so that the traction member 301 can flip the cover body 20 to a larger preset angle, ensuring that the cover body 20 does not interfere with the entry and exit of the cleaning basket.

[0055] In addition, the slider 302 at the first position is farther from the second edge 202 than the fixed end of the traction member 301, so that the traction member 301 is inclined on the cover 20, thereby providing a more stable supporting force for the cover 20 in the open notch 101 state.

[0056] Furthermore, as Figure 1 shown, the fixed end of the traction member 301 is located in the corner area 203 of the cover 20, and the corner area 203 is far from the first edge 201.

[0057] Since the fixed end of the traction member 301 is located in the corner area 203 of the cover 20 far from the first edge 201, that is, the free end of the traction member 301 is located in the corner area 203 of the cover 20 not connected to the trough 10, the moment of the traction member 301 pulling the cover 20 can be further increased, so that the cover 20 can be more easily and stably flipped to a preset angle.

[0058] In addition, the corner area 203 of the cover 20 usually has strong structural stability and can withstand a large tensile force. Therefore, setting the fixed end of the traction member 301 in the corner area 203 of the cover 20 can further stably flip the cover 20.

[0059] To further improve the stability of the cover 20 when flipping relative to the trough 10, in some embodiments, the number of the opening and closing mechanisms 30 is two, and the two opening and closing mechanisms 30 are used to open or close the same cover 20, thereby improving the stability of the cover 20 during the opening and closing processes.

[0060] Specifically, the fixed ends of the traction members 301 of the two opening and closing mechanisms 30 are respectively arranged close to the two second edges 202 of the cover 20, and the first position of the slider 302 of each opening and closing mechanism 30 can be located in the middle area of the slideway 40. This can make the slider 302 of each opening and closing mechanism 30 have as large a sliding stroke as possible.

[0061] When it is necessary to switch the cover 20 from the closed notch 101 state to the open state, the sliders 302 of the two opening and closing mechanisms 30 move from the second positions at both ends of the slideway 40 to the first position in the middle area of the slideway 40 respectively. The two sliders 302 move synchronously and approach each other, so that the two traction members 301 synchronously pull the cover 20. The two opening and closing mechanisms 30 can evenly share the gravity of the cover 20 and the rotational friction force between the cover 20 and the trough 10, reducing the damage or deformation that the cover 20 may cause due to excessive single-point force, and making the cover 20 be opened more stably.

[0062] When the cover body 20 is in the open state flipped to a preset angle, each sliding member 302 is in the first position in the middle region of the slideway 40, and the fixed ends of the traction members 301 of each opening and closing mechanism 30 respectively cover two corner regions 203 of the cover body 20, so that the two opening and closing mechanisms 30 are approximately two sides of a triangle, thereby being able to provide a more stable supporting force for the cover body 20 to keep the cover body 20 in this open state.

[0063] In order to improve the reliability of the sliding member 302 during movement, in some embodiments, as Figure 1 and Figure 4 shown, an anti-collision block 401 is further provided on the slideway 40, and when the two sliding members 302 are respectively in their first positions, they are located on both sides of the anti-collision block 401.

[0064] During the process of the opening and closing mechanism 30 opening the cover body 20, the two sliding members 302 move closer to each other. In order to prevent the two sliding members 302 from colliding with each other in some cases, an anti-collision block 401 is further provided in the middle region of the slideway 40. In this way, even if the two sliding members 302 do not stop in the first position in time in special cases and continue to move closer to each other, the two sliding members 302 will not collide with each other and cause damage, but will contact the anti-collision block 401 and be forced to stop on one side of the anti-collision block 401. Optionally, the anti-collision block 401 can be made of a flexible material.

[0065] Furthermore, as Figure 1 and Figure 5 shown, two stop members 402 are further provided on the slideway 40, and the stop members 402 are located at both ends of the slideway 40. Since the second position may be located at the end of the slideway 40, the stop members 402 located at both ends of the slideway 40 can prevent the sliding member 302 from sliding out of the slideway 40 when the sliding member 302 does not stop in the second position in time.

[0066] In order to improve the operation intelligence of the cleaning tank 01, in some embodiments, a plurality of sensors are further provided on the tank body 10, and the plurality of sensors are arranged corresponding to the slideway 40 for obtaining the position of the sliding member 302 on the slideway 40.

[0067] The plurality of position sensors can be located on one side of the slideway 40, which can not only prevent the plurality of sensors from interfering with the sliding of the sliding member 302, but also be as close as possible to the sliding member 302 to improve the detection accuracy. Optionally, the sensor can be an infrared sensor or an ultrasonic sensor, and the movement of the sliding member 302 will change the optical signal or acoustic signal received by the infrared sensor or the ultrasonic sensor, thereby triggering a change in the output signal of the sensor.

[0068] Optionally, corresponding inductive elements may also be provided on the slider 302. Exemplarily, the sensor may be a Hall sensor, and the inductive element may be a magnetic part; or the sensor may be a photoelectric sensor, and the inductive element may be a reflective element or a light-emitting element.

[0069] Furthermore, the cleaning tank 01 further includes an alarm device, which is used to send an alarm message to prompt the situation that the slider 302 moves and does not stop at the first position or the second position. When the slider 302 starts to move and does not stop at the first position or the second position, it indicates that the cover 20 may be in a state where it is not opened in place or does not completely close the notch 101. Therefore, it is necessary for the alarm device to send an alarm message to prompt the operator.

[0070] The alarm message can be in the form of sound, photoelectricity, or a combination of sound and photoelectricity to prompt the operator's attention. In the case of receiving the alarm message, the operator can promptly stop the operation of the solar cell cleaning device and troubleshoot to prevent damage to the cover 20, the cleaning basket, or the solar cells caused by the improper opening and closing of the cover 20.

[0071] To improve the automation level of the cleaning tank 01, the cleaning tank 01 further includes a driving assembly, which can drive the slider 302 to slide on the slideway 40 and accurately stop at the first position and the second position, ensuring the automatic opening and closing and accurate movement of the cover 20.

[0072] Optionally, the driving assembly may be a linear driving motor and a connecting member connecting the driving motor and the slider 302, or the driving assembly may be a cylinder assembly, a gear and rack assembly, or a lead screw assembly. As long as the driving assembly can drive the slider 302 to move on the slideway 40, the form of the driving assembly is not specifically limited in this application.

[0073] Since the cleaning solution for cleaning solar cells has the characteristics of strong acid and strong alkali, if the operator needs to manually operate the opening and closing of the cover 20, the operator may be injured due to accidental contact with the cleaning solution. However, driving the opening and closing mechanism 30 to work automatically through the driving assembly can greatly reduce the risk of accidental injury and improve the use safety of the solar cell cleaning equipment.
