Description

Technical Field

[0001] This invention relates to a sorting device, and more particularly to a TOPCon battery testing and sorting device. Background Technology

[0002] During the manufacturing process, TOPCon cells are typically sorted, collected, and packaged according to efficiency and color. However, with the increasing sophistication of TOPCon cell and module production, the requirements for incoming cells at the module end are gradually becoming more stringent. For example, after cells are sorted and packaged according to efficiency and color, the thickness differences of cells within the same grade are often overlooked. As a result, inconsistent cell thickness at the module end frequently leads to a series of problems during assembly, such as microcracks.

[0003] Chinese patent application CN202010094725.7 discloses a battery sorting device, including a base. A motor housing is fixedly installed on one side of the top surface of the base. A worktable is fixedly installed on the top of the motor housing. A first drive shaft is movably connected to one side of the worktable. A feeding box is fixedly installed on one side of the top of the worktable. A sorting turntable is movably installed on the top of the worktable, located between the first drive shaft and the feeding box. The sorting turntable includes a rotating disc. A second drive shaft is fixedly installed on the top of the turntable. Limiting grooves are evenly formed on the bottom of the turntable. Battery receiving columns are evenly fixedly installed on the outer ring of the turntable. A telescopic rod is fixedly installed at the bottom of the battery receiving column and the connecting rod of the turntable. A weighing and sorting block is movably connected to the bottom of the telescopic rod. This battery sorting device can easily sort batteries of different weights with high efficiency. In addition, we can also achieve fine-grained packaging of batteries by sorting them by thickness.

[0004] This invention proposes a refined testing and sorting device for TOPCon batteries that can sort them by thickness, thus avoiding complaints from the component end due to uneven battery thickness during classification and packaging. Summary of the Invention

[0005] To overcome a series of problems caused by the large thickness difference of batteries of the same grade due to the packaging of batteries according to efficiency and color during the manufacturing process of TOPCon batteries, which may lead to hidden cracks in the assembly process at the module end.

[0006] This invention is achieved through the following technical means:

[0007] A TOPCon battery testing and sorting device includes a base, a U-shaped base, a mounting frame, a limiting plate, a collection frame, a drive mechanism, and a placement mechanism. The U-shaped base is symmetrically fixed to the top left and right sides. Mounting frames are fixed to the middle of the upper right side of the left U-shaped base and the middle of the upper left side of the right U-shaped base. Limiting plates for pushing unqualified TOPCon batteries are fixed between the inner ends of the left and right mounting frames. A collection frame for collecting qualified TOPCon batteries is fixed between the lower parts of the front and rear sides of the left U-shaped base. A drive mechanism for providing power is installed between the two U-shaped bases and the base. A placement mechanism for placing TOPCon batteries is installed on the drive mechanism.

[0008] Furthermore, the drive mechanism includes a rotating shaft, V-belt pulleys, a belt, a drive motor, a transmission assembly, a fixed base, and a limiting strip. The rotating shaft is rotatably connected between the upper front and rear sides of the left and right sides of the U-shaped base. V-belt pulleys are fixedly connected to both the front and rear sides of the rotating shaft. A belt for driving the placement mechanism to reverse is wound between the two front V-belt pulleys and between the two rear V-belt pulleys. The belt is connected to the placement mechanism. The drive motor is installed in the middle of the right side of the top of the base. A transmission assembly is connected between the output shaft end of the drive motor and the front side of the right rotating shaft. The transmission assembly consists of two pulleys and a flat belt. One pulley is fixedly mounted on the output shaft end of the drive motor, and the other pulley is fixedly mounted on the front side of the right rotating shaft. The flat belt is wound between the two pulleys. A fixed base is rotatably connected between the middle of the left and right rotating shafts. A limiting strip for limiting the placement mechanism containing unqualified TOPCon batteries is symmetrically fixed to the top center of the fixed base.

[0009] Furthermore, the placement mechanism includes a U-shaped frame, guide shafts, sliders, a first spring, a sliding frame, a placement plate, a drive rack, gears, a rotating rod, and a torsion spring. Eight guide shafts are evenly spaced and fixed to the inner sides of the belts on both the front and rear sides. A U-shaped frame is fixed between the inner ends of each pair of guide shafts on the front and rear sides. Sliders are symmetrically embedded and slidably connected to the top of the U-shaped frame on both the front and rear sides. The bottom of the sliders is connected to the inner side of the U-shaped frame via a first spring. A sliding frame is fixed between the inner sides of the four sliders on each U-shaped frame. The sliding frames are located on the front and rear sides of the U-shaped frame. Rotary rods are rotatably connected between the left and right sides of the sliding frame. Gears are fixedly fitted at both ends of the rotating rods. Drive racks for driving the gears to rotate inward are slidably connected between the left and right sides of the front and rear of the sliding frame. The drive racks mesh with the gears. When the drive racks reverse, they contact the limit strips. A placement plate for placing the TOPCon battery is fixedly connected to the circumferential side of the rotating rod. The placement plate passes through the inside of the sliding frame. Torque springs are connected between the outer sides of the front and rear sides of the placement plate and the inner side of the sliding frame. The torsion springs are sleeved on the rotating rods.

[0010] Furthermore, it also includes a buffering mechanism for buffering defective TOPCon batteries. The buffering mechanism includes a receiving frame, a second spring, a movable plate, a baffle, and a third spring. The receiving frame for receiving defective TOPCon batteries is rotatably connected to the rear left side of the top of the fixed base. The second spring is symmetrically connected between the rear bottom side of the receiving frame and the inner side of the fixed base. The baffle is fixed to the middle of the bottom of the receiving frame. The movable plate for buffering TOPCon batteries is slidably connected to the bottom of the receiving frame. Fifteen third springs are evenly spaced between the bottom of the movable plate and the inner side of the receiving frame.

[0011] Furthermore, it also includes a shaking mechanism for shaking the TOPCon battery. The shaking mechanism includes a disc, protrusions, a sliding plate, an L-shaped strip, and a fourth spring. A sliding plate for shaking the TOPCon battery in the collection frame is slidably connected between the front and rear sides of the lower part of the collection frame. An L-shaped strip is fixed to the right rear side of the top of the sliding plate. A fourth spring is connected between the upper part of the inner rear side of the L-shaped strip and the lower part of the outer rear side of the left-side rotary seat. A disc is fixed circumferentially to the rear side of the left rotating shaft. Four protrusions for driving the L-shaped strip to move backward are fixedly fixed circumferentially at even intervals on the rear side of the disc.

[0012] Furthermore, it also includes guide rollers and guide rods. Fourteen guide rods are rotatably connected to the top of the placement plate, and guide rollers for guiding the TOPCon battery are fixed to the guide rods circumferentially.

[0013] Furthermore, it also includes a hexagonal block and an n-type limiting rod. The hexagonal block is fixedly connected to the guide shaft along the circumference, and the n-type limiting rods for limiting the hexagonal block are symmetrically fixed to the top of the fixed base. The n-type limiting rods are in contact with the hexagonal block.

[0014] Furthermore, the movable board is made of rubber.

[0015] The significant advancement of this invention lies in:

[0016] 1. Place the TOPCon battery into the placement mechanism from the upper right. Start the drive mechanism to rotate the placement mechanism in reverse. The rotation of the placement mechanism will rotate the TOPCon battery in reverse. When the TOPCon battery rotates in reverse and does not contact the limit plate, the TOPCon battery will continue to rotate and fall from the placement mechanism into the collection container. Unqualified TOPCon batteries will contact the limit plate and fall out of the placement mechanism. In this way, unqualified TOPCon batteries can be sorted out according to their thickness.

[0017] 2. When a defective TOPCon battery falls from the placement mechanism, it will fall onto the buffer mechanism, which will cushion the TOPCon battery before it falls into the collection container. This makes it easier for operators to collect and process defective TOPCon batteries.

[0018] 3. When the drive motor starts, the left rotating shaft also drives the shaking mechanism to operate. The shaking mechanism shakes the qualified TOPCon batteries that fall into the collection box. After shaking, the TOPCon batteries fall into the collection container. In this way, the TOPCon batteries can be prevented from getting stuck in the collection box and falling into the collection container for collection. Attached Figure Description

Detailed Implementation

[0031] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0032] Example 1

[0033] A TOPCon battery testing and sorting device includes a base 1, a U-shaped base 2, a mounting bracket 3, a limiting plate 4, a collection frame 5, a drive mechanism 6, and a placement mechanism 7. (See also...) Figures 1-7 As shown, the top of the base 1 is symmetrically connected by welding to install the U-shaped seats 2. The middle of the upper right side of the left U-shaped seat 2 and the middle of the upper left side of the right U-shaped seat 2 are both connected by welding to install the mounting brackets 3. The inner ends of the left mounting bracket 3 and the inner ends of the right mounting bracket 3 are fixedly connected to the limiting plates 4. When the TOPCon battery comes into contact with the limiting plate 4, the limiting plate 4 can push the unqualified TOPCon battery. The lower part of the front and rear sides of the left U-shaped seat 2 is fixedly connected to the collection frame 5. The collection frame 5 can collect qualified TOPCon batteries. The two U-shaped seats 2 and the base 1 are connected to the drive mechanism 6, which provides power. The drive mechanism 6 is equipped with the placement mechanism 7, and the operator can put the TOPCon battery into the placement mechanism 7.

[0034] The drive mechanism 6 includes a rotating shaft 61, a V-belt pulley 62, a belt 63, a drive motor 64, a transmission assembly 65, a fixed base 66, and a limit bar 67. Please refer to [link / reference]. Figure 1 and Figure 2As shown, a rotating shaft 61 is rotatably connected between the upper front and rear sides of the left and right sides of the U-shaped base 2. V-belt pulleys 62 are installed on both the front and rear sides of the rotating shaft 61 by welding. A belt 63 is wound between the two front V-belt pulleys 62 and between the two rear V-belt pulleys 62. The belt 63 is connected to the placement mechanism 7. When the belt 63 reverses, it can drive the placement mechanism 7 to reverse. A drive motor 64 is installed in the middle of the right side of the top of the base 1. A transmission assembly 65 is connected between the output shaft end of the drive motor 64 and the front side of the right rotating shaft 61. The transmission assembly 65 consists of two pulleys and a flat belt. One pulley is fixedly mounted on the output shaft end of the drive motor 64, and the other pulley is fixedly mounted on the front side of the right rotating shaft 61. The flat belt is wound between the two pulleys. A fixed seat 66 is rotatably connected between the middle of the left and right rotating shafts 61. A limit strip 67 is installed symmetrically on the top center of the fixed seat 66 by welding. When the placement mechanism 7 moves to the left, the limit strip 67 can limit the placement mechanism 7 containing unqualified TOPCon batteries.

[0035] The placement mechanism 7 includes a U-shaped frame 71, a guide shaft 72, a slider 73, a first spring 74, a sliding frame 75, a placement plate 76, a drive rack 77, a gear 78, a rotating rod 79, and a torsion spring 710. (See also...) Figures 1-7 As shown, eight guide shafts 72 are evenly spaced and fixed to the inner sides of the belts 63 on both the front and rear sides. A U-shaped frame 71 is installed between the inner ends of each pair of guide shafts 72 on the front and rear sides by welding. Slider blocks 73 are symmetrically embedded and slidably connected to the top of the U-shaped frame 71 on both the front and rear sides. A first spring 74 connects the bottom of the slider 73 to the inner side of the U-shaped frame 71. A sliding frame 75 is installed between the inner sides of the four sliders 73 on each U-shaped frame 71 by welding. Rotating rods 79 are rotatably connected between the left and right sides of the front and rear sides of the sliding frame 75. Gears 78 are fixedly fitted at both ends of the rotating rods 79. A drive rack 77 is slidably connected between the left and right sides of the front part and the left and right sides of the rear part of the sliding frame 75. The drive rack 77 meshes with the gear 78. When the gear 78 continues to reverse, the drive rack 77 can drive the gear 78 to rotate inward. When the drive rack 77 reverses, it contacts the limit strip 67. A placement plate 76 is installed on the upper edge of the rotating rod 79 by welding. The placement plate 76 passes through the inner side of the sliding frame 75. The operator can put the TOPCon battery into the placement plate 76. Torque springs 710 are connected between the outer sides of the front and rear sides of the placement plate 76 and the inner side of the sliding frame 75. The torsion springs 710 are sleeved on the rotating rod 79.

[0036] First, the operator places a collection container in the lower left of collection box 5, then places the TOPCon battery on the placement mechanism 7 from the upper right. The drive mechanism 6 is then activated, causing the placement mechanism 7 to reverse. This reversal of placement mechanism 7, in turn, causes the TOPCon battery to reverse. When the position of the TOPCon battery on placement mechanism 7 reaches the upper right, more TOPCon batteries can be placed into it. When the TOPCon battery is no longer in contact with the limit plate 4, placement mechanism 7 continues to reverse the battery. When the TOPCon battery reaches the lower left, it disengages from placement mechanism 7 and falls into collection box 5. The TOPCon batteries in frame 5 fall into the collection container. If a TOPCon battery reverses and comes into contact with the limiting plate 4, it indicates that the TOPCon battery is unqualified. The limiting plate 4 moves the TOPCon battery downwards, causing the placement mechanism 7 to move downwards to a suitable position. When the placement mechanism 7 continues to reverse and is limited by the drive mechanism 6, the placement mechanism 7 does not block the TOPCon battery, and the TOPCon battery falls out of the placement mechanism 7. After the TOPCon battery falls, the placement mechanism 7 resets and continues to reverse. This process is repeated to continuously sort the TOPCon batteries, preventing unqualified TOPCon batteries from being used and affecting safety. After all the TOPCon batteries have been sorted, the drive mechanism 6 is turned off, and the drive mechanism 6 stops driving the placement mechanism 7. The collection container is then picked up for subsequent use of qualified TOPCon batteries, and unqualified TOPCon batteries are collected for further processing.

[0037] When the TOPCon battery is placed into the placement mechanism 7 from the upper right, the drive motor 64 is started and reversed. The reverse rotation of the drive motor 64 drives the transmission component 65 to reverse, which in turn drives the right rotating shaft 61 to reverse. The reverse rotation of the right rotating shaft 61 drives the right V-belt pulley 62 to reverse, which in turn drives the belt 63 to reverse via the left V-belt pulley 62. The reverse rotation of the belt 63 drives the placement mechanism 7 to reverse, which in turn drives the TOPCon battery to reverse for sorting. If the TOPCon battery comes into contact with the limit plate 4, it means that the TOPCon battery is unqualified. The limit plate 4 moves the TOPCon battery downward to the appropriate position, and the placement mechanism 7 also moves downward to the appropriate position. The placement mechanism 7 continues to reverse and comes into contact with the limit bar 67. The limit bar 67 limits the placement mechanism 7. The operation of the placement mechanism 7 does not block the TOPCon battery, and the TOPCon battery falls out of the placement mechanism 7. After the TOPCon battery falls out, the placement mechanism 7 resets and continues to reverse. Once all the TOPCon batteries have been sorted, the drive motor 64 is turned off. The drive motor 64 stops driving the transmission component 65 to reverse, the transmission component 65 stops driving the right rotating shaft 61 to reverse, the V-belt pulley 62 stops driving the belt 63 to reverse, and the belt 63 stops driving the placement mechanism 7 to reverse.

[0038] First, the operator places the TOPCon battery between the two placement plates 76 from the upper right. The sliding frame 75 limits the TOPCon battery. Then, the drive motor 64 is started in reverse, the belt 63 reverses, driving the guide shaft 72 in reverse. The guide shaft 72 reverses, driving the return frame 71 in reverse. The return frame 71 reverses, driving the sliding frame 75 in reverse via the slider 73. The sliding frame 75 reverses, driving the TOPCon battery in reverse via the placement plate 76. When the TOPCon battery is no longer in contact with the limiting plate 4, the sliding frame 75 continues to drive the TOPCon battery in reverse via the placement plate 76. When the TOPCon battery has reversed to the lower left, it falls to the bottom. Inside collection box 5, the TOPCon battery falls into the collection container. If the TOPCon battery reverses and contacts the limiting plate 4, it indicates that the TOPCon battery is defective. The limiting plate 4 moves the TOPCon battery downward to the appropriate position. The TOPCon battery moves inward, causing the placement plate 76 to move downward. The downward movement of the placement plate 76 causes the sliding frame 75 to move downward via the rotating rod 79. The sliding frame 75 moves inward, causing the slider 73 to move downward. The first spring 74 is compressed. The inward movement of the sliding frame 75 also causes the drive rack 77 to move downward to the appropriate position. The sliding frame 75 continues to reverse, causing the drive rack 77 to reverse. When the drive rack 77 contacts the limiting bar 67, the limiting bar 67... 7. The drive rack 77 is stopped from reversing, and the sliding frame 75 continues to reverse, creating relative motion with the drive rack 77. This causes the drive rack 77 to drive the gear 78 to rotate. The rotation of the gear 78 causes the rotating rod 79 to rotate inward, causing the placement plate 76 to swing downward. The torsion spring 710 is compressed, and the placement plate 76 swings downward without blocking the TOPCon battery. The TOPCon battery falls out of the sliding frame 75 and disengages from the limiting plate 4. Due to the action of the first spring 74, the slider 73 moves upward, causing the sliding frame 75 to move upward. The sliding frame 75 moves outward, causing the rotating rod 79 to move upward and reset. The rotating rod 79 moves upward and resets. The drive gear 78 moves upward to reset, and the sliding frame 75 moves upward to reset, which in turn drives the drive rack 77 to move upward to reset. The drive rack 77 resets and disengages from the limit bar 67. Due to the action of the torsion spring 710, the placement plate 76 swings upward to reset, driving the rotating rod 79 to rotate upward to reset. The rotating rod 79 rotates outward to reset, driving the gear 78 to rotate upward to reset. The gear 78 rotates outward to reset, driving the drive rack 77 to move to the left to reset. The return frame 71 continues to reverse, driving the sliding frame 75 to reverse via the slider 73, which in turn drives the placement plate 76 to continue to reverse. This process repeats, continuously driving the TOPCon batteries to reverse for sorting, thus separating out unqualified TOPCon batteries. After all the TOPCon batteries have been sorted, the drive motor 64 is turned off, the belt 63 stops driving the return frame 71 to reverse via the guide shaft 72, and the return frame 71 stops driving the sliding frame 75 to reverse via the slider 73, which in turn stops driving the placement plate 76 to reverse.

[0039] Example 2

[0040] Based on Embodiment 1, a buffer mechanism 8 is also included. The buffer mechanism 8 includes a receiving frame 81, a second spring 82, a movable plate 83, a baffle 84, and a third spring 85. Please refer to [link to embodiment 1]. Figure 1 , Figure 8 and Figure 9 As shown, a receiving frame 81 is rotatably connected to the top left rear part of the fixed base 66. When a defective TOPCon battery falls, the receiving frame 81 can receive the defective TOPCon battery. A second spring 82 is symmetrically connected between the rear side of the bottom of the receiving frame 81 and the inner side of the fixed base 66. A baffle 84 is installed in the middle of the bottom of the receiving frame 81 by welding. The baffle 84 can limit the swing distance of the receiving frame 81. A movable plate 83 is slidably connected to the bottom of the inner side of the receiving frame 81. The movable plate 83 is made of rubber. When the TOPCon battery falls into the receiving frame 81, the movable plate 83 can buffer the TOPCon battery. Fifteen third springs 85 are evenly spaced between the bottom of the movable plate 83 and the inner side of the receiving frame 81.

[0041] It also includes a shaking mechanism 9, which comprises a disc 91, a protrusion 92, a sliding plate 93, an L-shaped strip 94, and a fourth spring 95. Please refer to 1. Figure 2 , Figure 10 and Figure 11 As shown, a sliding plate 93 is slidably connected between the front and rear sides of the lower part of the collection frame 5. When the sliding plate 93 moves back and forth, it can shake the TOPCon battery in the collection frame 5. An L-shaped strip 94 is installed on the right rear side of the top of the sliding plate 93 by welding. A fourth spring 95 is connected between the upper part of the inner rear side of the L-shaped strip 94 and the lower part of the outer rear side of the left-side rotary seat 2. A disc 91 is installed on the rear side of the left-side rotating shaft 61 by welding. Four protrusions 92 are fixedly fixed on the rear side of the disc 91 at even intervals along the circumference. When the protrusions 92 reverse, they can drive the L-shaped strip 94 to move backward.

[0042] When one collection container is placed in the lower left of collection frame 5, another collection container can be placed in the lower front of receiving frame 81. Then, when the placement plate 76 swings downwards without obstructing the TOPCon battery, the TOPCon battery falls from the sliding frame 75 into the receiving frame 81. The TOPCon battery contacts the movable plate 83, and due to the action of the third spring 85, the movable plate 83 cushions the TOPCon battery. Since the movable plate 83 is made of rubber, it provides better cushioning for the TOPCon battery. Furthermore, as the TOPCon battery continuously falls into the receiving frame 81, the TOPCon... The battery causes the receiving frame 81 to swing downwards, compressing the second spring 82. This downward swing of the receiving frame 81 causes the baffle 84 to swing downwards as well. The baffle 84 contacts the fixing seat 66 and stops swinging downwards, causing the receiving frame 81 to stop swinging downwards as well. The TOPCon batteries inside the receiving frame 81 slide into the collection container. When the TOPCon batteries fall out, the second spring 82 causes the receiving frame 81 to swing upwards to reset, causing the baffle 84 to swing upwards to reset as well. After all the TOPCon batteries have been sorted, the collection container is removed for further processing of the defective TOPCon batteries. This facilitates the collection and processing of defective TOPCon batteries by the operator.

[0043] When the drive motor 64 starts, the left rotating shaft 61 reverses, which in turn drives the disc 91 to reverse. The reverse rotation of the disc 91 drives the protrusion 92 to reverse, and the protrusion 92 contacts the L-shaped bar 94. The protrusion 92 drives the L-shaped bar 94 to move backward, stretching the fourth spring 95. The backward movement of the L-shaped bar 94 drives the sliding plate 93 to move backward. When the protrusion 92 continues to reverse and loses contact with the L-shaped bar 94, the action of the fourth spring 95 causes the L-shaped bar 94 to move forward and reset, driving the sliding plate 93 to move forward and reset. This process repeats, and the continuous back-and-forth movement of the sliding plate 93 shakes the TOPCon batteries in the collection frame 5, causing them to fall into the collection container. When the drive motor 64 is turned off, the left rotating shaft 61 stops driving the disc 91 to reverse, the disc 91 stops driving the protrusion 92 to reverse, and the L-shaped bar 94 stops driving the sliding plate 93 to move back and forth. This prevents the TOPCon batteries from getting stuck in the collection frame 5 and failing to fall into the collection container for collection.

[0044] Example 3

[0045] Based on Embodiments 1 and 2, it also includes a guide roller 10 and a guide rod 11. Please refer to [link / reference]. Figure 3 , Figure 5 and Figure 7 As shown, fourteen guide rods 11 are rotatably connected to the top of the placement plate 76. Guide rollers 10 are installed on the guide rods 11 by welding along the circumferential direction. When the placement plate 76 swings downward, the guide rollers 10 can guide the TOPCon battery.

[0046] It also includes a hexagonal block 12 and an n-type limit lever 13, please refer to [link / reference]. Figure 3 , Figure 8 and Figure 11 As shown, a hexagonal block 12 is installed on the guide shaft 72 by welding along the circumferential direction. An n-type limiting rod 13 is installed on the top of the fixed seat 66 by welding in a symmetrical manner. The n-type limiting rod 13 contacts the hexagonal block 12 and can limit the hexagonal block 12.

[0047] When the placement plate 76 swings downwards without obstructing the TOPCon battery, it also drives the guide rod 11 to swing downwards. The guide rod 11 then drives the guide roller 10 to swing downwards. As the TOPCon battery falls from the placement plate 76, the guide roller 10 guides it, allowing it to fall into the receiving frame 81, which in turn falls into the collection container. When the placement plate 76 swings upwards to reset, it drives the guide roller 10 to swing upwards to reset as well. This allows the TOPCon battery to fall more smoothly from the placement plate 76.

[0048] When the drive motor 64 starts, the belt 63 reverses, causing the guide shaft 72 to reverse as well. The reverse rotation of the guide shaft 72 then causes the hexagonal block 12 to reverse as well. When the hexagonal block 12 contacts the n-shaped limit rod 13, the limit rod 13 restricts the hexagonal block 12, thus supporting the guide shaft 72, and consequently, the retaining frame 71 and the belt 63. As the hexagonal block 12 continues to reverse, it disengages from the n-shaped limit rod 13. This prevents the retaining frame 71 from shifting position due to a loose belt 63.
