Description

Technical Field

[0001] The present invention relates to the technical field of cleaning devices, and particularly to a cleaning device for TOPCon batteries. Background Art

[0002] During the production process of TOPCon (Tunnel Oxide Passivated Contact) batteries, in order to remove surface oxides and improve the passivation effect, it is necessary to use a cleaning device to clean the surface of TOPCon battery wafers.

[0003] However, most of the existing cleaning devices adopt the method of horizontally placing or manually fixing the battery wafers. During cleaning, the battery wafers are prone to problems such as hidden cracks and broken pieces due to water flow impact or mutual collision. Moreover, the integration degree is relatively low. After cleaning, it is necessary to manually transfer the battery wafers to the drying equipment, which will not only increase the risk of fragmentation but also reduce the production efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a cleaning device for TOPCon batteries, which solves the technical problems that most of the existing cleaning devices adopt the method of horizontally placing or manually fixing the battery wafers and are prone to hidden cracks and broken pieces due to water flow impact or mutual collision, and has the advantage of being able to effectively avoid the collision damage between batteries.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: A cleaning device for TOPCon batteries includes a cleaning tank. A battery limiting mechanism is arranged on the cleaning tank, and a battery body is placed on the battery limiting mechanism. Battery conveying mechanisms are symmetrically arranged on both sides of the cleaning tank. A cleaning auxiliary mechanism is arranged above the battery limiting mechanism. The battery limiting mechanism and the battery conveying mechanism are used for batch automatic cleaning of the battery body, and the cleaning auxiliary mechanism is used for drying the battery body. After the staff places the battery body on the battery limiting mechanism, the battery limiting mechanism will move into the interior of the cleaning tank under the action of the battery conveying mechanism for cleaning. After cleaning is completed, the cleaning auxiliary mechanism will automatically perform hot air drying on the battery body.

[0006] Preferably, the battery limiting mechanism includes a storage rack. A number of groups of limiting clamping plates are equidistantly arranged on the storage rack. Circular through grooves are formed between adjacent two groups of limiting clamping plates. A limiting through groove is formed through the storage rack. An air pump assembly for inflating into the cleaning liquid is arranged at the bottom of the cleaning tank. During cleaning and processing, the staff will place the sheet-shaped battery body inside the limiting clamping plates, so that there is a certain interval between adjacent two battery bodies.

[0007] Preferably, rubber protrusions are arranged on the inner side of the limiting clamping plates to prevent the battery body from colliding with the limiting clamping plates due to shaking.

[0008] Preferably, the battery conveying mechanism includes mounting slide bars symmetrically arranged on both sides of the cleaning tank. A traction platform is movably mounted on the mounting slide bars. An electric telescopic rod for driving the traction platform to move up and down is fixedly mounted on the mounting slide bars. A limiting component is movably mounted on the traction platform. A drain valve is arranged on the side of the cleaning tank. When the electric telescopic rod extends or contracts, it will cause the traction platform to move in the vertical direction, thereby vertically conveying the battery body.

[0009] Preferably, the shape of the limiting component matches the shape of the limiting through groove. Only when the limiting component is aligned with the limiting through groove can the traction platform smoothly pass through the limiting through groove.

[0010] Preferably, the traction platform is slidably connected to the mounting slide bars, and the upper end of the electric telescopic rod is fixedly connected to the traction platform.

[0011] Preferably, the cleaning auxiliary mechanism includes a mounting frame fixedly mounted on the mounting slide bars. A hot air blower is fixedly mounted on the mounting frame. After the battery cleaning is completed, the hot air blower blows hot air downward to blow-dry the battery body.

[0012] Preferably, a distance sensor for monitoring the position of the storage rack is provided on the mounting frame to prevent the battery body from being too close to the hot air blower.

[0013] By means of the above technical solutions, the present invention provides a cleaning device for TOPCon batteries, which at least has the following beneficial effects:

[0014] 1. By setting the battery limiting mechanism and using the mutual cooperation between the limiting clamping plate and the rubber protrusions, the present invention can vertically fix the battery body, and there is a certain interval between adjacent two battery bodies, which can not only avoid the collision and damage between the batteries, but also ensure that the battery body is fully in contact with the cleaning liquid.

[0015] 2. By setting the battery limiting mechanism and using the mutual cooperation between the circular through groove and the air pump assembly, the present invention can significantly enhance the circulation of the cleaning liquid in the battery gaps, thereby realizing the flexible flushing of the battery surface, which can not only effectively improve the cleaning uniformity and efficiency, but also prevent the edges of the batteries from being damaged.

[0016] 3. By setting the battery conveying mechanism and using the mutual cooperation between the electric telescopic rod and the traction platform, the present invention can stably lift and lower the battery body, which can improve the working efficiency of battery cleaning and fishing to a certain extent, and at the same time can also avoid the direct contact between the staff and the cleaning liquid, and is convenient to use.

[0017] 4. The present invention simplifies the fixing and disassembling steps of the storage rack through the rotation locking mechanism of the limiting component by setting up a battery conveying mechanism, which can effectively shorten the non-operation time and meet the requirements of batch production and processing.

[0018] 5. The present invention can automatically dry the battery body after cleaning through the cooperation between the hot air blower and the distance sensor by setting up a cleaning auxiliary mechanism, forming an integrated cleaning-drying process with high integration, effectively reducing the manual intervention link, and improving the production efficiency.

DETAILED DESCRIPTION OF THE INVENTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1

[0029] The cleaning devices in the prior art mostly adopt the method of horizontal placement or manual fixing of battery cells. During cleaning, the battery cells are easily cracked or broken due to water flow impact or mutual collision. In addition, the integration is low, and the battery cells need to be manually transferred to the drying equipment after cleaning, which not only increases the risk of fragmentation, but also reduces production efficiency. In order to solve this technical defect in the prior art, Figures 1-5 As shown, this embodiment proposes a cleaning device for TOPCon batteries, which can vertically fix the battery body 5, and a certain interval is left between two adjacent battery bodies 5, which can effectively avoid collision damage between batteries. A battery limiting mechanism 2 is provided on the cleaning box 1 of the device, and the battery body 5 is placed on the battery limiting mechanism 2. Battery conveying mechanisms 3 are symmetrically provided on both sides of the cleaning box 1, and a cleaning auxiliary mechanism 4 is provided above the battery limiting mechanism 2. The battery limiting mechanism 2 and the battery conveying mechanism 3 are used for batch automatic cleaning of the battery body 5, and the cleaning auxiliary mechanism 4 is used for drying the battery body 5. After the staff puts the battery body 5 on the battery limiting mechanism 2, the battery limiting mechanism 2 will be moved to the inside of the cleaning box 1 for cleaning under the action of the battery conveying mechanism 3. After cleaning, the cleaning auxiliary mechanism 4 will automatically dry the battery body 5 with hot air.

[0030] Specifically, the battery limiting mechanism 2 includes a rack 201, on which a plurality of groups of limiting splints 202 are arranged at equal intervals, a circular through groove 203 is provided between two adjacent groups of limiting splints 202, and a limiting through groove 204 is provided through the rack 201. An air pump assembly 304 for inflating the cleaning liquid is provided at the bottom of the cleaning box 1. During the cleaning process, the staff will place the sheet-like battery body 5 into the interior of the limiting splint 202, so that there is a certain interval between two adjacent battery bodies 5. A rubber protrusion 205 is provided on the inner side of the limiting splint 202 to prevent the battery body 5 from colliding with the limiting splint 202 due to shaking.

[0031] According to the above content, if Figure 5 As shown, when the cleaning device is used to soak and clean the battery body 5, first, the staff will place multiple battery bodies 5 into the limiting clamp 202 in sequence, so that the battery bodies 5 remain in a vertical state, which can effectively prevent the battery bodies 5 from colliding with each other during the cleaning process.

[0032] Next, the storage rack 201 will move into the interior of the cleaning tank 1 under the action of the electric telescopic rod 303, so that the battery body 5 is fully in contact with the cleaning liquid inside the cleaning tank 1, realizing immersion cleaning. Moreover, during the immersion process, the air pump assembly 304 will automatically blow air upward from the bottom of the cleaning tank 1.

[0033] Next, gas will form bubbles in the cleaning liquid and flow upward through the circular through-hole 203, so that the cleaning liquid can flow between two adjacent battery bodies 5, which can effectively improve the effect of immersion cleaning.

[0034] In this embodiment, by setting the battery limiting mechanism 2 and using the mutual cooperation between the limiting clamping plate 202 and the rubber protrusion 205, the battery body 5 can be vertically fixed, and there is a certain interval between two adjacent battery bodies 5, which can not only avoid collision damage between the batteries, but also ensure that the battery body 5 is fully in contact with the cleaning liquid. Moreover, in this embodiment, by setting the battery limiting mechanism 2 and using the mutual cooperation between the circular through-hole 203 and the air pump assembly 304, the circulation of the cleaning liquid in the battery gap can be significantly enhanced, so as to realize the flexible flushing of the battery surface, which can not only effectively improve the cleaning uniformity and efficiency, but also prevent the battery edge from being damaged.

[0035] Embodiment Two

[0036] In order to improve the working efficiency of battery cleaning and fishing as much as possible, on the basis of Embodiment One, as Figure 1 、 Figure 2 、 Figure 5 and Figure 6 shown, this embodiment sets a battery conveying mechanism 3. Specifically, the battery conveying mechanism 3 includes mounting slide rods 301 symmetrically arranged on both sides of the cleaning tank 1. A traction platform 302 is movably mounted on the mounting slide rods 301. The traction platform 302 is slidably connected to the mounting slide rods 301. An electric telescopic rod 303 for driving the traction platform 302 to move up and down is fixedly mounted on the mounting slide rods 301. The upper end of the electric telescopic rod 303 is fixedly connected to the traction platform 302. A limiting component 305 is movably mounted on the upper end of the traction platform 302. The shape of the limiting component 305 matches the shape of the limiting through-hole 204. Only when the limiting component 305 is aligned with the limiting through-hole 204 can the traction platform 302 smoothly pass through the limiting through-hole 204. A drain valve 306 is arranged on the side of the cleaning tank 1. When the electric telescopic rod 303 extends or contracts, the traction platform 302 will move in the vertical direction, so as to vertically convey the battery body 5.

[0037] According to the above, when feeding, the staff will first place the battery body 5 on the storage rack 201, and then place the storage rack 201 between the two installation sliding rods 301. At this time, the limiting component 305 and the limiting through groove 204 are in a parallel state. Subsequently, the staff will pass the traction platform 302 through the limiting through groove 204, and then turn the limiting component 305 to make it perpendicular to the limiting through groove 204, so as to fix and limit the storage rack 201.

[0038] Next, the traction platform 302 will move vertically downward under the action of the electric telescopic rod 303, so as to convey the storage rack 201 and the battery body 5 into the interior of the cleaning tank 1. After the soaking and cleaning are completed, the traction platform 302 will move vertically upward under the action of the electric telescopic rod 303, so as to quickly lift the battery body 5 out of the cleaning liquid.

[0039] In this embodiment, by setting the battery conveying mechanism 3 and utilizing the mutual cooperation between the electric telescopic rod 303 and the traction platform 302, the battery body 5 can be stably lifted and lowered, which can improve the working efficiency of battery cleaning and fishing to a certain extent. At the same time, it can also prevent the staff from directly contacting the cleaning liquid, which is convenient to use. Moreover, in this embodiment, by setting the battery conveying mechanism 3 and utilizing the mutual cooperation between the limiting component 305 and the storage rack 201, the rotation locking mechanism of the limiting component 305 effectively simplifies the fixing and disassembly steps of the storage rack 201, and can effectively shorten the non-operation time, meeting the requirements of batch production and processing.

[0040] Embodiment Three

[0041] On the basis of the above embodiment, in order to improve the integration of the device, as Figure 1 and Figure 2 shown, this embodiment sets a cleaning auxiliary mechanism 4. Specifically, the cleaning auxiliary mechanism 4 includes a mounting frame body 401 fixedly installed on the mounting sliding rod 301. A hot air blower 402 is fixedly installed on the mounting frame body 401. After the battery cleaning is completed, the hot air blower 402 will blow hot air downward to blow-dry the battery body 5. A distance sensor 403 for monitoring the position of the storage rack 201 is provided on the mounting frame body 401 to prevent the battery body 5 from being too close to the hot air blower 402.

[0042] According to the above, after the soaking and cleaning are completed, the storage rack 201 will move upward under the action of the mounting sliding rod 301. At this time, the hot air blower 402 will automatically blow hot air downward to blow off the cleaning liquid remaining on the surface of the battery body 5, so as to dry the battery body 5.

[0043] Moreover, the distance sensor 403 monitors the height of the storage rack 201 in real time. When the storage rack 201 rises to a certain height, the distance sensor 403 automatically sends a signal to the plc controller to stop the electric telescopic rod 303 from extending, thereby preventing the temperature of the battery body 5 from being too high.

[0044] In this embodiment, by setting the cleaning auxiliary mechanism 4 and using the mutual cooperation between the hot air blower 402 and the distance sensor 403, the battery body 5 can be automatically dried after cleaning, forming an integrated cleaning-drying process with high integration, effectively reducing the manual intervention link, and can effectively improve the production efficiency.

[0045] The control method of the present invention is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present invention is mainly used to protect mechanical devices, so the control method and circuit connection of the present invention will not be explained in detail.

[0046] It should be noted that in this article, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.
