Description

Technical Field

[0001] The utility model relates to the technical field of solar cell manufacturing, in particular to a material unloading device for photovoltaic coating equipment. Background Art

[0002] During the manufacturing process of solar cells, they need to be coated by PECVD (plasma enhanced chemical vapor deposition) coating equipment. The loading process before coating arranges the cells on a carrier. After coating, the coated cells need to be transferred from the carrier to a conveyor belt for subsequent processes.

[0003] The unloading device for photovoltaic coating equipment in the related art uses a suction nozzle to absorb the battery cells on the carrier and transfer them to the conveyor belt. Since the carrier is affected by factors such as manufacturing deviation, wear, cold and hot deformation, the height of the battery cells on different carriers is different, and the height of the battery cells at different positions on the same carrier is also different. The lowering height of the suction nozzle when sucking the battery cell is fixed, resulting in different compression amounts when the suction nozzle sucks the battery cell. If the compression amount is too small, it is easy to cause leakage. If the compression amount is too large, if there is an empty cell on the carrier, the suction nozzle is easy to contact the carrier, causing the suction nozzle to be contaminated or even damaged. The contaminated suction nozzle will continue to leave suction nozzle marks on the battery cell during the subsequent suction process of the battery cell, resulting in defective battery cells.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The following describes a material unloading device 1 for photovoltaic coating equipment according to an embodiment of the present utility model with reference to the accompanying drawings.

[0026] like Figure 1 and Figure 2 As shown, the unloading device 1 for photovoltaic coating equipment according to an embodiment of the utility model includes a bracket 10, a nozzle bracket 20, a lifting drive device 30, a nozzle 40 and a distance measuring device 50.

[0027] The nozzle holder 20 is arranged on the bracket 10 so as to be liftable and horizontally movable. The lifting drive device 30 is in transmission connection with the nozzle holder 20. The nozzle 40 is arranged on the nozzle holder 20 and is suitable for sucking the battery cell 3 on the carrier 2. The distance measuring device 50 is electrically connected to the lifting drive device 30, and the distance measuring device 50 is arranged on the nozzle holder 20 and is suitable for measuring the distance between the distance measuring device 50 and the carrier.

[0028] Specifically, the carrier plate 2 coated by the coating equipment is conveyed to the bottom of the unloading device 1 for the photovoltaic coating equipment by the carrier plate conveyor belt 5, and the horizontal position of the carrier plate 2 is positioned by the positioning device.

[0029] The distance measuring device 50 measures the distance between it and the carrier plate 2. The measured data is compared with the standard data to obtain the height that needs to be compensated and the actual height that needs to be lowered. This process can be calculated by a controller such as a programmable controller.

[0030] The lifting drive device 30 drives the nozzle holder 20 to descend according to the actual required descending height, so that the nozzle 40 just contacts the battery cell 3. At the same time, the nozzle 40 starts to absorb the battery cell 3 with negative pressure.

[0031] After the battery cell 3 is sucked by the suction nozzle 40 , the lifting drive device 30 drives the suction nozzle frame 20 to rise, and then moves horizontally along the bracket 10 to above the battery cell conveyor belt 4 , and the suction nozzle 40 releases the battery cell 3 and releases the battery cell 3 onto the battery cell conveyor belt 4 .

[0032] Repeat the above steps until all the cells 3 on the carrier 2 are unloaded, wait for the next carrier 2 to arrive, and repeat the above unloading steps.

[0033] The unloading device for photovoltaic coating equipment in the related technology. Since the carrier is affected by factors such as manufacturing deviation, wear, and hot and cold deformation, the height of the cells on different carriers is different, and the height of the cells at different positions on the same carrier is also different. The lowering height of the suction nozzle when adsorbing the cell is fixed, resulting in different compression amounts when the suction nozzle adsorbs the cell. If the compression amount is too small, it is easy to cause leakage. If the compression amount is too large, if there is an empty cell on the carrier, the suction nozzle is easy to contact the carrier, causing the suction nozzle to be contaminated or even damaged. The contaminated suction nozzle will continue to leave suction nozzle marks on the cell during the subsequent adsorption of the cell, resulting in defective cells.

[0034] According to the unloading device 1 for photovoltaic coating equipment in the embodiment of the utility model, by setting a distance measuring device 50, the distance between the distance measuring device 50 and the carrier 2 can be measured by the distance measuring device 50, so that the lifting drive device 30 can drive the suction nozzle frame 20 and the suction nozzle 40 to descend according to the actual height of the carrier 2 detected by the distance measuring device 50. Compared with the unloading device for photovoltaic coating equipment in the related art, the descending height of the suction nozzle 40 can be compensated according to the actual height of the carrier 2, and the lifting drive device 30 can be driven according to the actual distance measured, so as to avoid different compression amounts when the suction nozzle adsorbs the battery cell due to different heights of the battery cell, thereby avoiding leakage caused by too small compression amount, avoiding contamination or even damage of the suction nozzle 40 due to too large compression amount, and further avoiding the contaminated suction nozzle 40 leaving suction nozzle marks on the battery cell, reducing the production of defective suction nozzle mark products, and making the unloading process more reliable.

[0035] Therefore, the unloading device 1 for photovoltaic coating equipment according to the embodiment of the utility model has the advantages of high reliability and the like.

[0036] The following describes a material unloading device 1 for photovoltaic coating equipment according to a specific embodiment of the utility model with reference to the accompanying drawings.

[0037] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the unloading device 1 for photovoltaic coating equipment according to an embodiment of the utility model includes a bracket 10, a nozzle bracket 20, a lifting drive device 30, a nozzle 40 and a distance measuring device 50.

[0038] Specifically, Figure 1 and Figure 2 As shown, the distance measuring device 50 is a non-contact distance measuring device, which can avoid interference between the distance measuring device 50 and the carrier 2 and the battery cell 3, thereby avoiding contamination of the battery cell 3.

[0039] More specifically, the distance measuring device 50 is a laser distance measuring device, which can improve the measuring speed of the distance measuring device 50, avoid adding a measuring process to affect the overall rhythm of material feeding, and ensure material feeding efficiency.

[0040] Optionally, the distance measuring device 50 and the lifting drive device 30 are configured so that the compression amount when the suction nozzle 40 adsorbs the battery cell 3 is less than or equal to 0.1 mm. Here, it is preferred that the distance measuring device 50 and the lifting drive device 30 are configured so that the compression amount when the suction nozzle 40 adsorbs the battery cell 3 is less than or equal to 0.05 mm. This can avoid contamination or damage to the suction nozzle 40 due to excessive compression.

[0041] Advantageously, if Figure 1 and Figure 2As shown, there are multiple suction nozzles 40 and they are arranged at intervals on the suction nozzle frame 20. In this way, multiple battery cells 3 can be sucked at the same time when the suction nozzle frame 20 descends once, thereby improving the unloading efficiency.

[0042] More advantageously, the lower ends of the plurality of suction nozzles 40 are flush. This allows the lifting heights of the plurality of suction nozzles 40 to be kept consistent, and the compression amounts of the plurality of suction nozzles 40 to be kept consistent, making it easy to adjust the lifting heights of the plurality of suction nozzles 40 simultaneously through the distance measuring device 50 on the suction nozzle frame 20.

[0043] It should be understood that the more nozzles 40 there are, the higher the material unloading efficiency is, but the more serious the situation is that the compression amount of the nozzles is different due to the different heights of the battery cells at different positions on the same carrier. The number of nozzles 40 can be adjusted according to actual needs.

[0044] For example, 98 battery cells are arranged in an array on the carrier 2. The multiple suction nozzles 40 simultaneously suck 14 battery cells 3. The unloading of the battery cells 3 on one carrier 2 is completed by sucking 7 times.

[0045] Figure 1 The figure shows a material unloading device 1 for photovoltaic coating equipment according to some examples of the present utility model. Figure 1 As shown, the bracket 10 includes a translation track 11 and a mobile frame 12. The mobile frame 12 is slidably arranged on the translation track 11, and the nozzle frame 20 is movably arranged on the mobile frame 12. In this way, the horizontal movement of the nozzle frame 20 can be achieved by sliding the mobile frame 12 on the translation track 11, and the lifting and lowering of the nozzle frame 20 on the mobile frame 12 can be achieved to lift the nozzle 40, thereby realizing the movement of the nozzle 40 in two degrees of freedom, which is convenient for unloading the battery cell 3.

[0046] Specifically, Figure 1 As shown, the mobile frame 12 is movably arranged on the translation track 11 between the grabbing position and the unloading position. The mobile frame 12 is located above the carrier plate 2 when in the grabbing position and above the battery cell conveyor belt 4 when in the unloading position. In this way, the battery cell 3 can be moved from the carrier plate 2 to the battery cell conveyor belt 4 by the movement of the mobile frame 12 between the grabbing position and the unloading position, which facilitates the unloading of the battery cell 3.

[0047] More specifically, the lifting drive device 30 includes a motor and a screw rod, wherein the motor is arranged on the moving frame, the screw rod is connected to the motor by transmission, and the nozzle frame 20 is threadedly engaged with the screw rod. In this way, the screw rod can be driven to rotate by the motor, and the screw rod is threadedly engaged with the nozzle frame 20 to convert the rotation into lifting movement of the nozzle frame 20 along the axial direction of the screw rod.

[0048] Optionally, the unloading device 1 for the photovoltaic coating equipment is a plasma enhanced chemical vapor deposition (PECVD) coating equipment. In this way, the unloading device 1 can be used in the unloading process of the plasma enhanced chemical vapor deposition coating equipment, which is convenient for the plasma enhanced chemical vapor deposition coating equipment to unload materials and ensure the reliability of unloading.

[0049] Other structures and operations of the unloading device 1 for photovoltaic coating equipment according to the embodiment of the utility model are known to ordinary technicians in the field and will not be described in detail here.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.
