DETAILED DESCRIPTION

[0030] 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.

[0031] The TOPCon battery cleaning device provided by some embodiments of the present invention will be described below with reference to the accompanying drawings.

[0032] Embodiment 1:

[0033] Various chemical reagents are used in the battery manufacturing process, which may leave residues on the battery surface. Figure 1-Figure 4 As shown, the TOPCon battery cleaning device provided by the present invention comprises a housing 100, on which a flushing mechanism 200 for cleaning batteries is provided, which can flush multiple batteries at the same time, and can wash away the above-mentioned residues to avoid adverse effects on battery performance, and a drying mechanism 300 for drying batteries, which removes moisture on the surface of the batteries, and ensures that the batteries are subsequently processed and used in a dry environment, thereby ensuring the stability of battery performance;

[0034] The flushing mechanism 200 includes a first clamping seat 204 and a second clamping seat 205 which are obliquely installed on the inner wall of the shell 100, a first limiting rod 206 is inserted in the first clamping seat 204, a second limiting rod 208 and a third limiting rod 209 are inserted in the second clamping seat 205, the batteries in the first clamping seat 204 and the second clamping seat 205 are staggered, the first nozzle group 202 and the second nozzle group 203 are respectively installed at the diagonal corners in the shell 100, the staff turns the knob 207 to make it move outward away from the first limiting rod 206, after pulling out the first limiting rod 206, put the battery to be cleaned into the first clamping seat 204, insert the first limiting rod 206, tighten the knob 207 to complete the fixation of the battery, the second clamping seat 205 is fixedly installed at the rear of the first clamping seat 204, the second limiting rod 208 is installed inside the second clamping seat 205, and the second limiting rod 208 is installed on the second On the lower side of the clamping seat 205, a third limiting rod 209 is installed inside the second clamping seat 205, and the third limiting rod 209 is installed on the upper side of the second clamping seat 205. The knob 207 outside the third limiting rod 209 is turned to disengage the third limiting rod 209 outward, and the third limiting rod 209 is pulled out, and the battery is placed in the second clamping seat 205. The battery in the second clamping seat 205 will be placed above the second limiting rod 208, and the third limiting rod 209 is inserted. Tighten the knob 207 to complete the fixation. If the number of batteries to be cleaned increases, the first limiting rod 206 is kept inside the first clamping seat 204, and the battery is placed in the first clamping seat 204. The second limiting rod 208 and the third limiting rod 209 are taken out and the battery is placed at the bottom of the second clamping seat 205. The second limiting rod 208 and the third limiting rod 209 are installed, and the remaining batteries are placed above the third limiting rod 209 inside the second clamping seat 205;

[0035] A large amount of moisture will remain on the surface of the battery after rinsing. If it is not removed in time, the liquid may cause the battery to rust and corrode, affecting the performance and life of the battery. In order to solve the above problems, the drying mechanism 300 includes a first transmission shaft 302 and a second transmission shaft 303 respectively installed on the outside of the first clamping seat 204 and the second clamping seat 205. The first transmission shaft 302 and the second transmission shaft 303 are both fixedly connected with a connecting plate 304, and a guide tube 301 for blowing air to the battery is installed on the connecting plate 304. The guide tubes 301 on both sides of the battery blow warm air to both sides of the battery respectively.

[0036] Since the fixed-position air guide 301 can only transport hot air to one place and cannot dry the entire battery, in order to solve the above problem, a hot air blower 305 is installed on the outside of the shell 100, and the hot air blower 305 is connected to the air guide 301 through a pipeline. A belt assembly 306 is provided between the first transmission shaft 302 and the second transmission shaft 303. The belt assembly 306 includes pulleys mounted on the first transmission shaft 302 and the second transmission shaft 303. The pulleys are connected by belt transmission, which can drive the first transmission shaft 302 and the second transmission shaft 303 to deflect at the same time. The first transmission shaft 302 and the second transmission shaft 303 respectively drive the air guide 301 to swing through the connecting plate 304, thereby increasing the area of ​​blowing hot air and increasing the range of drying the battery.

[0037] Furthermore, the positions of the air outlets on the guide tubes 301 on both sides are symmetrically distributed, and are respectively used to transport hot air to the front and back sides of the battery, so that both sides of the battery can be dried at the same time, further improving work efficiency.

[0038] According to the embodiment, by flushing multiple batteries at the same time, it can be ensured that each battery can be cleaned evenly, thereby improving the consistency between the batteries. In a battery pack, consistency is a very important performance indicator, which directly affects the overall performance and life of the battery pack. The flushing mechanism 200 can ensure that the surface state of each battery is basically the same, which helps to improve the consistency and stability of the battery pack.

[0039] Embodiment 2:

[0040] Combination Figure 3-Figure 5As shown, on the basis of Example 1, a spur gear 315 is mounted on the second transmission shaft 303, a limit frame 310 is fixedly connected to the outer side of the shell 100, a rack 311 meshing with the spur gear 315 is slidably connected to the limit frame 310, and a transmission component for driving the rack 311 to move left and right is provided on the limit frame 310. The transmission component causes the rack 311 to move left and right. The movement of the rack 311 drives the second transmission shaft 303 to swing through the spur gear 315. The second transmission shaft 303 drives the first transmission shaft 302 to swing through the belt assembly 306, thereby driving the second transmission shaft 303 and the guide tube 301 on the first transmission shaft 302 to swing, so that fresh hot air can continuously act on the battery surface, so that the water evaporates faster, thereby shortening the drying time and improving production efficiency.

[0041] Specifically, the transmission assembly includes a slide plate 312 fixedly connected to the bottom of the rack 311, a spring 313 is fixedly connected between the slide plate 312 and the inner wall of the frame, a slide bar 314 is fixedly connected to the slide plate 312 and is slidably connected to the limit frame 310, and a connecting disk 309 is fixedly connected to the end of the slide bar 314. The housing 100 is also fixedly equipped with a motor 307, and an eccentric wheel 308 corresponding to the connecting disk 309 is fixedly connected to the output end of the motor 307. When the motor 307 is started, the eccentric wheel 308 is driven to rotate, and the rotation of the eccentric wheel 308 and the contact with the connecting disk 309 will push the corresponding side to move, and the slide bar 314 is fixedly connected to the limit frame 310. The slide plate 312 moves with the connecting disk 309, and the slide plate 312 drives the rack 311 to move. When the eccentric wheel 308 moves from the connecting disk 309, the spring 313 pushes the slide plate 312 to reset the rack 311. When the rack 311 resets, it drives the second transmission shaft 303 to reverse through the spur gear 315, so that the second transmission shaft 303 and the guide tube 301 on the first transmission shaft 302 swing, which can avoid the battery from being over-dried or insufficiently dried locally due to uneven heating, ensure that each battery can be dried evenly and effectively, and improve the overall drying consistency of the battery.

[0042] Furthermore, a water storage drawer 101 for collecting sewage is slidably connected to the bottom of the shell 100, and a grid plate 102 is provided on the water storage drawer 101. The first limit rod 206, the second limit rod 208 and the third limit rod 209 are all equipped with knobs 207 for locking the first limit rod 206, the second limit rod 208 and the third limit rod 209.

[0043] According to the embodiment, when cleaning is completed, the cleaning water inside the device enters the water storage layer through the drainage hole. A grid plate 102 is installed inside the water storage drawer 101. The cleaning water entering the water storage layer flows into the water storage drawer 101. The grid plate 102 inside the water storage drawer 101 filters impurities in the water. The filtered fragments are above the grid plate 102. A handle is fixedly installed on the outside of the water storage drawer 101. After cleaning, the staff pulls the handle to open the water storage drawer 101. The fragments on the grid plate 102 can be uniformly processed. After removing the grid plate 102, the cleaning water inside the water storage drawer 101 is discharged.

[0044] Embodiment three:

[0045] Combination Figure 3 As shown, on the basis of the first embodiment, an inclined plate 103 is fixedly connected to one side of the mesh plate 102, and a waste box 104 is placed in the water storage drawer 101. The waste box 104 is provided with a plurality of filter holes, and the waste box 104 is located on the side of the inclined plate 103. Since the impurities on the mesh plate 102 will clog the mesh holes, and the water flow will drive the impurities to move, the impurities are concentrated in the waste box 104, which is convenient for the subsequent treatment of the impurities.

[0046] Specifically, the first nozzle group 202 and the second nozzle group 203 are respectively connected to external water pipes, a partition 201 is fixedly connected to the shell 100, and the first nozzle group 202 is installed on the partition 201, which can transport water to the first nozzle group 202 and the second nozzle group 203, and then rinse the battery.

[0047] Through the above embodiment, it can be known that: the staff rotates the knob 207 to make it move outward away from the first limiting rod 206. After pulling out the first limiting rod 206, the battery to be cleaned is placed in the first clamping seat 204, the first limiting rod 206 is inserted, and the knob 207 is tightened to complete the fixation of the battery. The second clamping seat 204 is fixedly installed with the second clamping seat 205 at the rear, and the second limiting rod 208 is installed inside the second clamping seat 205. The second limiting rod 208 is installed on the lower side of the second clamping seat 205. The third limiting rod 209 is installed on the upper side of the second clamping seat 205. The knob 207 on the outer side of the third limiting rod 209 is rotated to make it disengage from the third limiting rod 209 outward, and the third limiting rod 209 is pulled out, and the battery is placed in the second clamping seat 205. The battery in the second clamping seat 205 will be placed Place it above the second limiting rod 208, insert the third limiting rod 209, tighten the knob 207 to complete the fixation. If the number of batteries to be cleaned increases, keep the first limiting rod 206 inside the first clamping seat 204, put the battery into the first clamping seat 204, take out the second limiting rod 208 and the third limiting rod 209, put the battery into the bottom of the second clamping seat 205, install the second limiting rod 208 and the third limiting rod 209, put the remaining batteries above the third limiting rod 209 inside the second clamping seat 205, start the device, and the cleaning water enters from the water inlet and is sprayed out by the nozzles on the first nozzle group 202 and the second nozzle group 203, thereby cleaning the fixed batteries in the device. Due to the action of the first limiting rod 206, the second limiting rod 208 and the third limiting rod 209, the batteries are staggered, and a better cleaning effect is achieved during the cleaning process.
