Description

Technical Field

[0001] This invention relates to the field of TOPCon battery technology, specifically to a TOPCon battery cleaning and passivation device. Background Technology

[0002] TOPCon batteries, short for tunneling oxide passivated contact batteries, are a new type of solar cell. During production, TOPCon batteries require passivation. A search revealed a patent with publication number CN222869322U. This patent describes a process where a motor rotates a reciprocating screw, causing a sliding seat and cleaning brush to move back and forth. Because the cleaning brush is in close contact with the battery body, its movement removes impurities adhering to the battery. Simultaneously, a fan generates sufficient suction, which is then used to remove the cleaned impurities through a suction nozzle. However, this patent found that the passivation cleaning process only cleans the top surface of the battery, neglecting the sides. To improve passivation quality, a comprehensive cleaning is necessary. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a TOPCon battery cleaning and passivation device, which solves the technical problem that existing TOPCon battery cleaning and passivation equipment cannot thoroughly clean the battery, can only clean the upper surface of the battery body, and is difficult to clean the sides.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A TOPCon battery cleaning and passivation device includes a belt conveyor, two support blocks are fixedly connected to the top of the belt conveyor, a transverse drive assembly is installed between the two support blocks, and a cleaning assembly is installed at the bottom of the transverse drive assembly. The cleaning assembly includes a telescopic sleeve, a slider, a track support, a rotating platform, and a cleaning brush head. The telescopic sleeve is installed at the movable end of the transverse drive assembly, the slider is fixed at the bottom of the telescopic sleeve, both ends of the track support are fixed to the belt conveyor, the track support passes through the slider, the rotating platform is fixed at the bottom of the slider, and the cleaning brush head is installed at the movable end of the rotating platform. The track support includes a middle section, an arc section, and a longitudinal section. The middle section is a horizontal block, the two arc sections are fixed at both ends of the middle section, and the longitudinal section is fixed at the bottom of the arc section.

[0005] Furthermore, the lateral drive assembly includes a ball screw and a motor. Both ends of the ball screw are rotatably connected to the support block. The motor drives the ball screw to rotate, and the telescopic sleeve is fixed to the nut of the ball screw.

[0006] Furthermore, a passivation machine body is installed on the top of the belt conveyor, an impurity adsorption component is installed between the passivation machine body and the support block, and a battery storage component is installed at the end of the belt conveyor away from the cleaning component.

[0007] Furthermore, the impurity adsorption assembly includes a U-shaped frame, a suction nozzle, a fan, a first hose, a second hose, and a connecting block. The U-shaped frame is fixed to the top of the belt conveyor, the fan is fixed to the top of the U-shaped frame, the suction nozzle is installed on the movable end of the ball screw, the suction nozzle is connected to the fan through the first hose, the second hose is connected to the exhaust port of the fan, the connecting block is fixed to the top of the U-shaped frame, and the second hose passes through the connecting block and is slidably connected to it.

[0008] Furthermore, the battery storage assembly includes a housing, a storage frame, a placement plate, electric push rods, and a push plate. The housing is fixed to one side of the belt conveyor, the storage frame is slidably connected to the inner wall of the housing, multiple placement plates are fixed inside the storage frame, four electric push rods are embedded in the bottom of the housing, the push plate is fixed to the top of the piston rod of the four electric push rods, the push plate is in contact with the bottom of the storage frame, and a support rod is installed at the bottom of the housing.

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1 To clean both sides of the battery while cleaning the top surface, please refer to... Figures 1-3This embodiment proposes a TOPCon battery cleaning and passivation device, including a belt conveyor 2. The battery body 3 is placed on the belt conveyor 2 and conveyed. Two support blocks 4 are fixedly connected to the top of the belt conveyor 2. A transverse drive assembly 5 is installed between the two support blocks 4. A cleaning assembly 6 is installed at the bottom of the transverse drive assembly 5. The cleaning assembly 6 includes a telescopic sleeve 61, a slider 62, a track bracket 63, a rotating table 64, and a cleaning brush head 65. The telescopic sleeve 61 is installed at the movable end of the transverse drive assembly 5. The slider 62 is fixed at the bottom of the telescopic sleeve 61. Both ends of the track bracket 63 are fixed on the belt conveyor 2. The track bracket 63 passes through the slider 62. The rotating table 64 is fixed at the bottom of the slider 62. The cleaning brush head 65 is installed at the movable end of the rotating table 64. The track bracket 63 includes a middle section, an arc section, and a longitudinal section. The middle section is a horizontal block. The two arc sections are fixed at both ends of the middle section. The arc sections surround the edge of the battery body 3. The longitudinal section is fixed at the bottom of the arc section.

[0019] In use, the battery body 3 is placed on the belt conveyor 2, which drives the battery body 3 to move. The lateral drive component 5 drives the slider 62 to reciprocate left and right. When the slider 62 moves directly above the track support 63, it moves to its highest point along the track support 63. At this point, the telescopic sleeve 61 is at its shortest. The rotating table 64 drives the cleaning brush head 65 to rotate and clean the upper surface of the battery body 3. When the lateral drive component 5 drives the slider 62 to move from the middle of the track support 63 to both ends, the slider 62 slides along the track support 63 and its height gradually decreases, causing the cleaning brush head 65 to move to the side of the battery body 3 and descend until the slider 62 moves to both ends of the track support 63. As the slider 62 moves along the arc segment surrounding the edge of the battery body 3, the cleaning brush head 65 moves along the side of the battery body 3. When the rotating table 64 drives the cleaning brush head 65 to rotate, it cleans the side of the battery body 3 from different angles. The track bracket 63 of the corresponding size is selected according to the height of the battery body 3 so that the cleaning brush head 65 can clean the side of the battery body 3 when it is lowered to the lowest point. This can achieve cleaning of the upper surface and the side of the battery body 3. Compared with the method of cleaning only the upper surface of the battery body 3, the cleaning of the battery body 3 is more thorough. By using the track bracket 63 customized for the battery body 3, the cleaning needs of battery bodies 3 of different sizes can be met.

[0020] Considering the wear and tear that may occur when the cleaning brush head 65 rubs against the battery body 3 over a long period of time, replaceable track brackets 63 of different heights are installed. After the cleaning brush head 65 has been used for a period of time, the track brackets 63 with reduced height are replaced, so that the overall height of the cleaning brush head 65 is lowered. Even if the cleaning brush head 65 wears down after being lowered, it can still contact the battery body 3 on the belt conveyor 2, which is convenient to adapt to the wear and tear that may occur after the cleaning brush head 65 has been used for a long time.

[0021] To move the cleaning brush head 65 to the top and side of the battery body 3, and to complete the cleaning of the upper surface and sides of the battery body 3, refer to... Figure 2 The lateral drive assembly 5 includes a ball screw 51 and a motor 52. Both ends of the screw of the ball screw 51 are rotatably connected to the support block 4. The motor 52 drives the screw of the ball screw 51 to rotate. The telescopic sleeve 61 is fixed on the nut of the ball screw 51.

[0022] In use, the motor 52 drives the ball screw 51 to move, and the nut of the ball screw 51 moves along the length of the screw, thereby driving the telescopic sleeve 61 and the cleaning brush head 65 to move to different positions of the battery body 3, so that the cleaning brush head 65 can clean different positions of the battery body 3.

[0023] To facilitate the removal of impurities cleaned from the battery body 3, refer to... Figure 3 A passivation machine body 7 is installed on the top of the belt conveyor 2. An impurity adsorption component 8 is installed between the passivation machine body 7 and the support block 4. A battery storage component 9 is installed at the end of the belt conveyor 2 away from the cleaning component 6. The impurity adsorption component 8 includes a U-shaped frame 81, a suction nozzle 83, a fan 84, a first hose 85, a second hose 86, and a connecting block 87. The U-shaped frame 81 is fixed on the top of the belt conveyor 2. The fan 84 is fixed on the top of the U-shaped frame 81. The suction nozzle 83 is installed on the movable end of the ball screw 51. The suction nozzle 83 and the fan 84 are connected by the first hose 85. The second hose 86 is connected to the exhaust port of the fan 84. The connecting block 87 is fixed on the top of the U-shaped frame 81. The second hose 86 passes through the connecting block 87 and is slidably connected to it.

[0024] In use, the suction nozzle 83 moves with the nut of the ball screw 51 and moves synchronously with the cleaning brush head 65. When the cleaning brush head 65 sweeps away the impurities on the battery body 3, the fan 84 sucks away the swept impurities through the suction nozzle 83 and then discharges them from the hose 86. It can draw air in the direction of the cleaning brush head 65, directly sucking away the impurities when the cleaning brush head 65 sweeps away the impurities on the surface of the battery body 3, reducing the impurities scattered on the belt conveyor 2.

[0025] In order for the slider 62 and cleaning brush head 65 to move left and right, they can rise and fall along the height of the track bracket 63, as shown in the reference. Figure 2 The telescopic sleeve 61 includes a large cylinder and a small cylinder. The top of the large cylinder is fixed to the movable end of the ball screw 51, and one end of the small cylinder extends into the interior of the large cylinder.

[0026] In use, the small cylinder slides along the inner wall of the large cylinder. When the slider 62 moves to the middle section of the track support 63, the small cylinder enters the deepest part of the large cylinder. At this time, the overall length of the telescopic sleeve 61 is the shortest. When the slider 62 moves to both ends, the small cylinder moves to the outside of the large cylinder, making the overall length of the telescopic sleeve 61 longer.

[0027] Example 2 To better collect the battery body 3 after surface passivation, refer to Figures 1-4 Based on Embodiment 1, the battery storage assembly 9 includes a housing 91, a storage frame 92, a placement plate 93, an electric push rod 95, and a push plate 96. The housing 91 is fixed to one side of the belt conveyor 2. The storage frame 92 is slidably connected to the inner wall of the housing 91. Multiple placement plates 93 are fixed inside the storage frame 92. Four electric push rods 95 are embedded in the bottom of the housing 91. The push plate 96 is fixed to the top of the piston rod of the four electric push rods 95. The push plate 96 is in contact with the bottom of the storage frame 92. A support rod is installed at the bottom of the housing 91. A magnet 10 is embedded inside the push plate 96. A magnet 21 is embedded at the bottom of the storage frame 92. The magnet 10 is in contact with the magnet 211.

[0028] In use, the electric push rod 95 pushes the storage frame 92 up and down until the belt conveyor 2 is at the same height as the placement plate 93 above which is not full of battery bodies 3. In this way, the belt conveyor 2 can transport the battery bodies 3 above it to the placement plate 93. When the placement plate 93 facing the belt conveyor 2 is full of battery bodies 3, the electric push rod 95 drives the other placement plates 93 on the storage frame 92 that are not full of battery bodies 3 to move to the position facing the belt conveyor 2. The magnetic connection provides stability during lifting and lowering. When it is necessary to remove the storage frame, it can be separated from the push plate by overcoming the magnetic force, which facilitates the centralized collection of the passivated battery bodies 3, and at the same time enhances the stability of the storage frame 92 during lifting and lowering.
