DETAILED DESCRIPTION

[0044] Some embodiments of the present application will be described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present application, and are not intended to limit the protection scope of the present application.

[0045] It should be noted that in the description of the present application, the terms indicating the direction or positional relationship of "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like are based on the direction or positional relationship shown in the drawings, which is only for the convenience of description, and does not indicate or imply that the device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application. In addition, the terms "first", "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance. In addition, in the description of the present application, "a plurality of" means at least two.

[0046] In addition, it should also be noted that in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection or integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0047] As described in the background, the feeding table of the photovoltaic cell texturing machine device places the flower basket base, and the phenomenon of alkali crystallization will occur after a long time of operation. The position difference of the mechanical arm will also occur during a long time of operation, resulting in the phenomenon of missing flower baskets and dropping flower baskets when the mechanical arm takes the flower baskets on the feeding table.

[0048] Referring to the drawingsFigure 1 , Figure 1 is a schematic diagram of the flower basket base of the existing etching machine loading table. As shown in Figure 1 , it includes a flower basket base, a flower basket, and a photoelectric sensor arranged on the flower basket base. Among them, the photoelectric sensor is mainly used to monitor the position state of the flower basket in real time, detect whether the mechanical arm misses the flower basket or the flower basket falls when taking the flower basket at the loading table. For example, when the flower basket is missed or falls on the flower basket base, the photoelectric sensor will receive reflected light from the surface of the flower basket, which will trigger an alarm signal to inform the operator or the control system to process.

[0049] However, the position of the fallen flower basket is not fixed, and the photoelectric sensor has a visual blind area, making it difficult to detect the position of the flower basket. In this case, the sheet feeding mechanism will default to no flower basket at the station, and will continue to send the flower basket to the flower basket station, causing the basket to be hit, seriously affecting the yield and chip rate indicators of the battery.

[0050] Currently, some manufacturers of etching machines will regularly calibrate the position parameters of the mechanical arm grabbing the flower basket and the parameters of the sheet feeding mechanism of the loading table to the flower basket station to ensure the accuracy of the position, reduce the number of times the mechanical arm drops the basket, and prevent the phenomenon of basket collision caused by the sheet feeding mechanism continuing to send the flower basket. However, this method can only reduce the number of times the mechanical arm drops the basket, but cannot completely avoid the dropping of the basket, and cannot solve the problem of the loading table failing to detect the flower basket after missing or dropping the flower basket, and continuing to send the flower basket, causing the basket to be hit.

[0051] In order to solve the above problems, the present application provides an etching device for photovoltaic cells. It includes a controller, a loading table, an etching tank and a unloading table.

[0052] Among them, the etching device is a tank type etching device. The controller is responsible for the operation control of the entire etching device, including coordinating the actions of various components, adjusting process parameters, etc. The loading table is used to place the silicon wafer to be etched, ensuring that the silicon wafer can be stably transported to the etching area. The etching tank is the part that actually performs the etching treatment of the silicon wafer surface, including an alkali tank, a water tank, an acid tank and a drying tank, etc., mainly through physical or chemical methods to roughen the surface of the silicon wafer. The silicon wafer after etching treatment will be placed on the unloading table for subsequent processing or inspection.

[0053] It should be pointed out that in order to solve the technical problem of the existing etching machine device that the loading table fails to detect the flower basket after missing or dropping the flower basket, and continues to send the flower basket, causing the basket to be hit, affecting the yield and chip rate indicators of the battery, the present application mainly improves the structure of the loading table. As for the controller, the etching tank and the unloading table, the existing structure and connection relationship can be maintained, which is not limited here.

[0054] Referring to the accompanying Figure 2 , Figure 2is a schematic diagram of a part of a texturing apparatus according to an embodiment of the present application. As shown in Figure 2 , it comprises a feeding table 1 and a controller 2. The feeding table 1 comprises a flower basket conveying mechanism 11, a plurality of groups of flower basket seats 12 and flower baskets 13 arranged in parallel.

[0055] The pressure sensor 121 is arranged on the flower basket seat 12 and is used to detect the pressure signal of the flower basket seat 12.

[0056] Further, the controller 2 of the texturing apparatus is connected to the pressure sensor 121. The controller 2 is used to receive the pressure signal and output a first control signal based on the pressure signal. The first control signal is used to control the flower basket conveying mechanism 11 to stop conveying the flower basket 13 to the flower basket seat 12.

[0057] The connection between the controller 2 of the texturing apparatus and the pressure sensor 121 can be wired connection (such as cable connection, bus connection, etc.) or wireless connection (such as Bluetooth connection, Wi-Fi connection, ZigBee connection, etc.), which is not shown in the figure.

[0058] According to the above embodiment, the pressure signal on the flower basket seat can be detected by the pressure sensor, and the flower basket conveying mechanism can be timely controlled to stop conveying the flower basket to the flower basket seat according to the pressure signal. This effectively solves the problem of basket collision caused by the mechanical arm dropping the flower basket and continuing to convey the flower basket after missing the flower basket. This can greatly reduce the loss, reduce the battery chip rate, improve the production capacity, and has low modification cost and remarkable effect.

[0059] The texturing apparatus for the above-mentioned photovoltaic cell will be further described below.

[0060] As shown in Figure 2 , in some embodiments, each group of flower basket seats comprises two flower basket seats. A pressure sensor 121 is arranged in the middle of each flower basket seat 12. The pressure sensor 121 can detect the pressure signal on the flower basket seat 12. When the mechanical arm misses the flower basket or drops the flower basket, the flower basket will fall at any position of the flower basket seat 12. At this time, the pressure signal detected by the pressure sensor 121 is sent to the controller 2, so that the controller 2 can timely control the flower basket conveying mechanism 11 to stop conveying the flower basket 13 to the flower basket seat 12, thereby avoiding the basket collision.

[0061] However, since the position where the flower basket falls is not fixed, when the flower basket happens to fall in an area that cannot be covered by the pressure sensor 121, the accurate pressure signal may not be detected.

[0062] Therefore, in some embodiments, a plurality of pressure sensors can be arranged on the flower basket seat 12. Referring to FIG. 2, the plurality of pressure sensors 121 arranged on the flower basket seat 12 can detect the pressure signal on the flower basket seat 12. Figure 3 , Figure 3is a schematic diagram of the main structure of a flower basket base according to an embodiment of the present application.

[0063] As shown in Figure 3 , two pressure sensors 122 and 123 are arranged on each flower basket base 12. Among them, the pressure sensors 122 and 123 can be arranged equidistantly according to the length of the flower basket base 12. In this way, the detection range of the pressure sensors 122 and 123 can cover different positions of the flower basket base 12, and no matter which side the flower basket falls on, at least one pressure sensor will detect the pressure signal.

[0064] In this way, the pressure signals at various positions of the flower basket base can be more comprehensively detected, thereby improving the detection accuracy and reliability of the flower basket missing and the flower basket falling, and ensuring that the flower basket can be found in time when it is missing or falling.

[0065] It should be pointed out that the above examples of the number and position of the pressure sensors arranged on the flower basket base are only illustrative. In actual application, those skilled in the art can arrange corresponding pressure sensors according to the size and length of the flower basket base to comprehensively detect the pressure signals at various positions of the flower basket base, which is not limited herein.

[0066] Moreover, in actual application, the pressure sensors can be installed on the flower basket base of the existing loading table of the wafering equipment. For example, the flower basket base shown in Figure 1 is disassembled, perforated, the diameter of the round hole can be 25mm, two round holes are punched equidistantly on each flower basket base, and a corresponding size of circular pressure sensor is purchased for embedded installation and wiring, so as to obtain the flower basket base shown in Figure 3 This way is easy to install, has low modification cost, and does not have a detection blind area.

[0067] Further, referring to the accompanying drawings Figure 4 , Figure 4 is a schematic diagram of part of the structure of a wafering equipment according to another embodiment of the present application. As shown in Figure 4 , the loading table 1 further comprises a mechanical arm 14, which is used to extract the flower basket 13 on the flower basket base 12.

[0068] The mechanical arm 14 is provided with a flower basket detection device 141, which is used to detect the missing flower basket signal or the flower basket falling signal of the mechanical arm 14, and output a trigger instruction based on the missing flower basket signal or the flower basket falling signal.

[0069] The flower basket detection device 141 can be a pressure sensor. When the mechanical arm 14 normally picks up the flower basket 13, the pressure sensor detects the pressure of the flower basket 13. If the mechanical arm 14 misses the flower basket or the flower basket accidentally falls, the pressure sensor cannot detect the corresponding pressure value, thereby obtaining a missed flower basket signal or a flower basket falling signal.

[0070] The flower basket detection device 141 can also be a photoelectric sensor, such as a reflection type or a reflection type photoelectric sensor. When the mechanical arm 14 normally picks up the flower basket 13, the photoelectric sensor can detect that the flower basket is in a preset position. If the mechanical arm 14 misses the flower basket or the flower basket accidentally falls, the photoelectric sensor cannot detect the flower basket, thereby obtaining a missed flower basket signal or a flower basket falling signal.

[0071] It should be pointed out that the above examples of the flower basket detection device are only illustrative. In actual application, those skilled in the art can set up corresponding flower basket detection devices according to specific scenes. In addition to the pressure sensor and the photoelectric sensor mentioned above, machine vision equipment such as a camera or a position sensor can also be included, which is not limited here.

[0072] Further, the controller 2 can be connected with the flower basket detection device 141. The controller 2 is used to receive the trigger instruction output by the flower basket detection device 141, and receive the pressure signal sent by the pressure sensor 122 and / or 123 based on the trigger instruction.

[0073] Specifically, the controller 2 can receive the trigger instruction output by the flower basket detection device 141. When the controller 2 receives the trigger instruction output by the flower basket detection device 141, it indicates that the mechanical arm 14 may miss the flower basket or the flower basket accidentally falls when picking up the flower basket 13. At this time, the controller 2 can receive the pressure signal sent by the pressure sensor 122 and / or 123, and output a control signal based on the pressure signal.

[0074] The controller 2 can include a programmable logic controller or a comparator.

[0075] The programmable logic controller (PLC) is a kind of digital electronic device, which is used to automatically control the operation process of machine or production line. When the controller 2 is a PLC, the pressure signal detected by the pressure sensor can be converted into a current signal through a conversion circuit. For example, the change of pressure will cause the change of strain gauge resistance, and the change of resistance can be converted into the change of current through a bridge circuit.

[0076] Further, the PLC can determine whether there is a missing or fallen flower basket on the flower basket base 12 according to the received current signal. Specifically, the PLC compares the received current signal with a pre-stored normal current range. The pre-stored normal current range is the current range when no flower basket 13 is placed on the flower basket base 12. Therefore, if the current signal received by the PLC is within the normal current range, it is determined that there is no missing or fallen flower basket on the flower basket base 12; if the current signal received by the PLC exceeds the normal current range, it is determined that there is a missing or fallen flower basket on the flower basket base 12, and a control signal can be output at this time to control the flower basket conveying mechanism 11 to stop conveying the flower basket 13 to the flower basket base 12, so as to avoid basket collision.

[0077] The comparator is an electronic component for comparing the sizes of two input signals and outputting corresponding signals according to the comparison results. Common comparators include voltage comparators, current comparators, etc. When the controller 2 is a voltage comparator, the pressure signal detected by the pressure sensor can be converted into a voltage signal by a conversion circuit and input into the voltage comparator.

[0078] Further, the voltage comparator has two input terminals and one output terminal. One of the input terminals is connected to a constant current voltage, which is a pre-set reference voltage value representing the voltage reference when there is no flower basket on the flower basket base 12. The other input terminal receives the voltage signal from the pressure sensor. The voltage comparator can determine whether there is a fallen flower basket by comparing the sizes of the two input voltages. Specifically, if the voltage value of the voltage signal received by the voltage comparator is less than the constant current voltage, it is determined that there is no missing or fallen flower basket on the flower basket base 12; if the voltage value of the voltage signal received by the voltage comparator is greater than the constant current voltage, it is determined that there is a missing or fallen flower basket on the flower basket base 12, and a control signal can be output at this time to control the flower basket conveying mechanism 11 to stop conveying the flower basket to the flower basket base 12, so as to avoid basket collision.

[0079] Further, referring to FIG. 1, the controller 2 is connected to the pressure sensor 14 and the drive 15. The controller 2 is used to output a first control signal to the drive 15 to control the drive 15 to stop driving the flower basket conveying mechanism 11. Figure 5 , Figure 5 is a partial structure schematic diagram of a texturing apparatus according to another embodiment of the present application. As shown in FIG. 1, the loading table 1 further comprises a drive 15 for driving the flower basket conveying mechanism 11 to convey the flower basket 13 to the flower basket base 12. The controller 2 is connected to the drive 15, and the controller 2 is used to output a first control signal to the drive 15 to control the drive 15 to stop driving the flower basket conveying mechanism 11. Figure 5

[0080] The flower basket conveying mechanism 11 can be a loading slide, a conveying belt, a mechanical arm conveying structure, etc., which is not limited here.

[0081] Further, taking the flower basket conveying mechanism 11 as a loading slide for example, referring to FIG. 1, the loading table 1 further comprises a drive 15 for driving the loading slide to convey the flower basket 13 to the flower basket base 12. The controller 2 is connected to the drive 15, and the controller 2 is used to output a first control signal to the drive 15 to control the drive 15 to stop driving the loading slide. Figure 6 ​, Figure 6 is a schematic diagram of the main structure of the feeding slide table according to an embodiment of the present application.

[0082] As shown in Figure 6 , the feeding slide table 11 can include, from top to bottom, a flower basket card seat 111, a slide table base 112, a slide table connecting rod 113, a cylinder top seat 114, a cylinder rod 115, a cylinder 116, a slide block 117, and a cylindrical guide rail 118.

[0083] The above is a further description of the flower basket conveying mechanism 11.

[0084] In some embodiments, the controller 2 can also be connected with the mechanical arm 14, and the controller 2 can be used to output a second control signal to the mechanical arm 14 based on the trigger instruction. Wherein, the second control signal is used to control the mechanical arm 14 to stop extracting the flower basket 13 on the flower basket base 12.

[0085] Specifically, when the controller 2 receives the trigger instruction output by the flower basket detection device 141, it indicates that the mechanical arm 14 may have missed picking up the flower basket or the flower basket has fallen accidentally when grabbing the flower basket 13. At this time, the controller 2 can output a second control signal to the mechanical arm 14 to control the mechanical arm 14 to stop extracting the flower basket 13 on the flower basket base 12.

[0086] Further, in some embodiments, the texturing device for photovoltaic cells provided by the present application can also include an alarm, which can be arranged at any position of the texturing device, which is not limited here.

[0087] Wherein, the controller can be connected with the alarm, for controlling the alarm to issue an alarm.

[0088] Specifically, when the controller 2 receives the trigger instruction output by the flower basket detection device 141, or the controller 2 determines that there is a missed or fallen flower basket on the flower basket base 2, it can send a control signal to the alarm to control the alarm to issue an alarm, so as to timely remind the staff to pay attention to these abnormal situations, so that they can take measures to handle them quickly, and ensure the stable operation and production efficiency of the texturing device.

[0089] Further, until the staff handles it, the controller 2 can control the driver 15 to drive the flower basket conveying mechanism 11 to continue conveying the flower basket 13 to the flower basket base 12, and control the mechanical arm 14 to continue extracting the flower basket 13 on the flower basket base 12.

[0090] The above is a further description of the alarm.

[0091] In some embodiments, Figure 2 As shown in Figure 1The photoelectric sensor shown, such as a basket diffuse reflection photoelectric sensor, can be used to detect whether there is a flower basket 13 on the flower basket base 12.

[0092] Further, the photoelectric sensor can be connected with the controller 2 and send a control signal to the controller 2.

[0093] By jointly detecting whether there is a missed or fallen flower basket on the flower basket base through the pressure sensor and the photoelectric sensor, a more accurate detection result can be obtained, and when the mechanical arm misses a flower basket or a flower basket falls, the controller can control the flower basket conveying mechanism to stop conveying the flower basket to the flower basket base in time, effectively solving the problem of basket collision, greatly reducing the loss, reducing the battery fragment rate, improving the production capacity, and the transformation cost is low, the effect is remarkable.
