DETAILED DESCRIPTION

[0029] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of 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 making creative efforts should fall within the scope of protection of the present invention.

[0030] like Figure 1 and Figure 3As shown, an ultrasonic double-cell detector for solar cell production, according to one embodiment of the present invention, includes a support assembly 1, within which are mounted an ultrasonic transmitter module, an ultrasonic receiver module, a signal processing module, a control and logic module, and a power supply module. The ultrasonic double-cell detector transmits ultrasonic signals and receives signals reflected from the surface or interior of the solar cell. If the solar cell is stacked, the propagation path and reflection characteristics of the ultrasonic wave will change, resulting in the received signal being different from normal. The signal processing module analyzes these differences to determine whether a double-cell is present and displays the result or issues an alarm. It also includes an angle adjustment component 5, in which one ultrasonic probe is located above the angle adjustment component 5, and a downward pressure component is installed on one side wall of the angle adjustment component 5; a conveying mechanism 2 for realizing the transmission of battery cells before and after detection, and another ultrasonic probe is located below the conveying mechanism 2, and one side wall of the conveying mechanism 2 is connected to the downward pressure component; a separation mechanism 4 for adsorbing and realizing the separation of double-cell batteries, and the separation mechanism 4 is located between the conveying mechanism 2 and the angle adjustment component 5. When double or multiple cells are detected, the separation mechanism 4 first adsorbs the upper battery cell vertically downward, and then one side of the angle adjustment component 5 drives the conveying mechanism 2 and the battery cell to move vertically downward while driving the separation mechanism 4 and the angle adjustment component 5 to rotate synchronously, generating an angle of 5 to 10 degrees. This method makes it easier to separate the battery cells and will not cause damage to the battery cells when the angle is generated, thereby avoiding the situation where stacking still occurs after adsorption.

[0031] like Figure 2 and Figure 3As shown, the conveying mechanism 2 includes a first conveying component 201 and a third conveying component 203, a second conveying component 202 is installed between the first conveying component 201 and the third conveying component 203, a fourth conveying component 204 is installed on one side of the second conveying component 202, and the second conveying component 202 and the fourth conveying component 204 are both installed on the inner wall of the supporting shell 101, and the battery cell is first transported from the first conveying component 201 to the top of the second conveying component 202. When passing through the second conveying component 202, the ultrasonic probes located at the upper and lower ends of the second conveying component 202 respectively detect the battery cell. When it is detected that the battery cell is a double-cell battery, the separation mechanism 4 adsorbs the top battery cell, and then the conveying mechanism 2 continues to work to drive the bottom battery cell to the third conveying component 203 Move, then the fourth conveyor component 204 will place the top battery cell above the second conveyor component 202, and then the ultrasonic probe will perform a second inspection on the top battery cell. After detecting that it is a single battery cell, the battery cell continues to move toward the third conveyor component 203; when it is detected that there are multiple battery cells above the second conveyor component 202, the separation mechanism 4 will transport the upper battery cells to the top of the fourth conveyor component 204 in sequence. When it is detected that the battery cell above the second conveyor component 202 is a single battery cell, the second conveyor component 202 continues to work and transports the battery cell to the third conveyor component 203, and then the fourth conveyor component 204 works to transport the upper battery cell to the top of the second conveyor component 202, and repeat the above steps to achieve the separation of double or multiple battery cells.

[0032] like Figures 3 to 5 and Figure 7As shown, four groups of dampers 2021 are installed on the bottom end face of the second transmission component 202, and support blocks 2023 are installed on the bottom end faces of the four groups of dampers 2021. Springs 2022 are installed on the outside of the four groups of dampers 2021 and on one side wall of the support block 2023. A support component 1 is installed on the side wall of the angle adjustment component 5. The support component 1 includes a support shell 101, and a first support plate 102 is installed on the top side wall of the support shell 101, and a second support plate 103 is installed on the top side wall of the first support plate 102. A pair of ultrasonic probes are respectively installed on the inner wall of the supporting shell 101 and the bottom end surface of the second supporting plate 103, and the pair of ultrasonic probes are on the same vertical line. A limit block 104 matching the downward pressure component is fixedly connected to one side wall of the supporting shell 101, and a limit slot 1041 is provided on the side wall of the limit block 104. A first supporting plate 102 is installed on the top side wall of the supporting shell 101, and a rotating motor 501 is installed on one side wall of the first supporting plate 102. The angle adjustment component 5 includes a rotating plate 502, and a second rotating rod 503 is integrally formed on the side walls of both ends of the rotating plate 502. The output end of the rotating motor 501 is fixedly connected to a side wall of one group of the second rotating rods 503, and the other group of the second rotating rods 503 rotates on the inner wall of the supporting shell 101. A second detection avoidance groove 504 is provided on the end surface of the rotating plate 502. The function is to open a path for the ultrasonic detection head. After all, obstruction affects the detection of double-chip batteries. Four groups of cylinders 505 are installed on the bottom end face of the rotating plate 502. The pressing assembly includes a pressing block 506 and a pressing rod 2024. The pressing block 506 is integrally formed on one side wall of the rotating plate 502. A square groove 5061 is provided on one side wall of the pressing block 506. A rotating hole 5062 is provided on a pair of inner walls of the pressing block 506 located in the square groove 5061. A rotating column matching the rotating hole 5062 is integrally formed on the top side wall of the pressing rod 2024. The outer walls of one end of a pair of rotating columns are rotatably connected to the inner wall of the rotating hole 5062. A slider 2025 is integrally formed on the bottom end face of the pressing rod 2024. A side wall of the slider 2025 is fixedly connected to the side wall of the second transmission assembly 202, and the outer wall of the slider 2025 is adhered to and slidably connected to the inner wall of the limit block 104.When it is detected that there is a double-cell battery above the second conveying component 202, the separation mechanism 4 first absorbs and contacts the battery cell vertically downward, and then the rotating motor 501 drives the rotating plate 502 to rotate in the support shell 101, so that the rotating plate 502 moves downward close to the side of the lower pressure block 506, thereby driving the lower pressure block 506 and the lower pressure rod 2024 to move downward, so that the rotating column on the lower pressure rod 2024 rotates in the rotating hole 5062, so that the lower pressure rod 2024 and the slider 2025 move vertically downward, so that the outer wall of the slider 2025 slides on the inner wall of the limit block 104, thereby driving the second conveying component 202 to move vertically downward as a whole, and the spring 2022 is compressed at the same time, thereby driving the second conveying component 202 and the battery cell to move vertically downward, and at the same time the angle adjustment component 5 drives one side of the separation mechanism 4 to tilt downward. At this time, the position of the battery cell adsorbed by the separation mechanism 4 remains unchanged, but the angle rotates with the angle adjustment component 5. The second conveying component 202 drives the battery cell to move downward, and the separation mechanism 4 drives the top battery cell to rotate the angle, so that the two battery cells start to separate from one side, and the separation effect is good. As the second conveying component 202 moves downward, the entire battery cell is driven to separate, thereby realizing the rapid separation of the two-cell battery.

[0033] It should be noted that: if the separation mechanism 4 moves downward and directly tilts downward to be adsorbed, and the bottom battery cell does not move downward, when the top battery cell rotates at an angle, one side moves upward and the other side moves downward. The battery cell on the side that moves downward is likely to cause wear or damage to the bottom battery cell, thereby increasing the defective rate of battery cell separation.

[0034] like Figure 5 、 Figure 6 and Figure 8As shown, an automatic conveying system 3 is installed on one side wall of the first support plate 102, and a slide groove 301 matching the automatic conveying system 3 is provided on the inner wall of the first support plate 102, and a conveying block 302 matching the automatic conveying system 3 is slidably connected to the inner wall of the slide groove 301, and a mounting hole 3021 is provided on one side wall of the conveying block 302, and the separation mechanism 4 includes a bracket 401, and a first detection avoidance groove 402 is provided on the outer wall of the bracket 401. The function of the first detection avoidance groove 402 is to open a path for the ultrasonic detection head. After all, the obstruction affects the detection of the double-chip battery. Auxiliary blocks 403 are fixedly connected to a pair of end faces of the bracket 401, and a first rotating rod 404 is integrally formed on the side walls of the pair of auxiliary blocks 403. The outer wall of the first rotating rod 404 is adhered to and rotatably connected to the inner wall of the mounting hole 3021, and multiple groups of vacuum suction cups 405 are installed on the bottom end face of the bracket 401, and an ion wind knife 6 is installed on one side of the vacuum suction cup 405 on one side of the bracket 401. During operation, the automatic conveying system 3 is turned on to drive the conveying block 302 to move in the slide 301, thereby realizing the change of the position of the separation mechanism 4. When a double-cell battery is detected, the automatic conveying system 3 drives the conveying block 302 to move to the top of the battery cell, and then moves downward along the slide 301, while driving the bracket 401 to move downward, so that the vacuum suction cup 405 is attached to the top of the top battery cell and adsorbed. Then the cylinder 505 installed under the angle adjustment component 5 works and retracts to fit the top end face of the bracket 401. Then the angle adjustment component 5 rotates, thereby driving the separation mechanism 4 and the top battery cell to rotate. At this time, the outer end face of the first rotating rod 404 rotates on the inner wall of the mounting hole 3021. At the same time, the angle adjustment component 5 drives the conveying mechanism 2 and the bottom battery cell to move downward, thereby realizing the separation of the battery cells. After the separation is completed, the angle adjustment component 5 drives the separation mechanism 4 and the top battery cell to automatically return to the center, and then performs subsequent work.

[0035] When in use, the ultrasonic detector is located at the upper and lower ends of the second conveying component 202. The battery cells are detected by the ultrasonic detector when passing through the second conveying component 202 from the first conveying component 201. After detecting double-cell or single-cell batteries, the double-cell or multi-cell battery cells are separated through the separation mechanism 4 and the angle adjustment component 5. Through the cooperation between the separation mechanism 4, the second conveying component 202, the angle adjustment component 5 and the pressing component, the battery cells remain intact during separation.
