Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, in particular to a material loading alignment device and a transfer device. Background Art

[0002] In the production process of solar cells such as heterojunction cells, after the film is coated on the cell, the cell is transported to the production equipment of the next process (such as the screen printing process) by automatic conveying equipment. Traditional automatic conveying equipment includes a carrier, a loading platform, and a suction cup device. The carrier transports the cell to the loading platform, and the loading platform is equipped with a positioning piece to align the cell. The suction cup device absorbs and transfers the cell on the loading platform for loading.

[0003] However, in order to improve efficiency and other performance, the size of the battery cell is sometimes changed, for example, the size is changed from 182mm×183.75mm to 210mm×105mm. At this time, the end of the battery cell will be lifted up by the alignment parts when it is transported to the loading platform, that is, overlapping occurs. In this case, the suction cup device cannot accurately adsorb the battery cell, and the uneven adsorption force on the battery cell causes leakage. In severe cases, it may cause hidden cracks inside the battery cell. There will also be errors when swinging the cell, resulting in an overall offset rate of 2.5% for the battery cell, affecting the production yield. For this reason, when the size of the battery cell changes, it is necessary to stop the machine and modify the loading platform to adapt to the new size, which causes inconvenience and reduces production efficiency.

[0039] The utility model provides a loading alignment device and a transfer device including the loading alignment device, which can be applied in the production process of solar cells and can adapt to the alignment of cells of different sizes before loading, so that the handling device can accurately pick up the cells for loading. The following is exemplarily described with the production of solar cells, however, the applicable objects of the utility model are not limited thereto, for example, it can also be applied to other sheets.

[0040] Fig. 1 is a schematic diagram of the structure of a transfer device according to an embodiment. Fig. 2 to Fig. 4 are partial schematic diagrams of a loading and positioning device in the transfer device shown in Fig. 1.

[0041] 1 to 4 , a loading and alignment device 100 according to an embodiment includes a transmission mechanism 110 , a first alignment mechanism 120 , a second alignment mechanism 130 , and an adjustment drive mechanism 140 .

[0042] The transmission mechanism 110 is used to transmit the battery cell 40, and has an alignment station 111 on the transmission mechanism 110. When the battery cell 40 is transmitted to the alignment station 111, the position is aligned so that the handling device 310 can accurately pick up the battery cell 40 for loading.

[0043] The first alignment mechanism 120 and the second alignment mechanism 130 are respectively disposed on opposite sides of the transmission mechanism 110. The first alignment mechanism 120 and the second alignment mechanism 130 are used to cooperate to limit the battery cell 40 to the alignment station 111, so that the battery cell 40 is aligned at the alignment station 111.

[0044] The adjusting driving mechanism 140 is connected to the first alignment mechanism 120 and / or the second alignment mechanism 130 to drive the first alignment mechanism 120 and / or the second alignment mechanism 130 to move closer to or farther from the alignment station 111. For battery cells 40 of different sizes, the adjusting driving mechanism 140 adjusts the positions of the first alignment mechanism 120 and / or the second alignment mechanism 130 to adapt to the alignment of battery cells 40 of different sizes.

[0045] As shown in FIG1 , in some examples, the loading alignment device 100 further includes a dimension measuring mechanism 160. In the conveying direction of the battery cell 40, the dimension measuring mechanism 160 is located upstream of the alignment station 111. By setting the dimension measuring mechanism 160 to obtain the dimension information of the battery cell 40, it can be determined whether the adjustment driving mechanism 140 needs to drive the position of the alignment mechanism and the distance to be adjusted.

[0046] The dimension measuring mechanism 160 is, for example, disposed above the conveying mechanism 110 .

[0047] The size measuring mechanism 160 may include but is not limited to a graphics acquisition mechanism. The graphics acquisition mechanism is, for example, an industrial camera. Further, the graphics acquisition mechanism includes a line scan camera. The line scan camera can better obtain the size information of the battery cell 40 during the movement of the battery cell 40.

[0048] As shown in Fig. 1, in some examples, the loading and aligning device 100 further includes a first movable guide rail 170. The dimension measuring mechanism 160 is disposed on the movable guide rail and can move along the movable guide rail, and the position of the dimension measuring mechanism 160 can be flexibly adjusted.

[0049] As shown in FIG1 , in some examples, the loading alignment device 100 further includes a light-emitting mechanism 200. The light-emitting mechanism 200 is arranged opposite to the size measuring mechanism 160. The light-emitting mechanism 200 is, for example, arranged below the transmission mechanism 110. In some examples, the light-emitting mechanism 200 is a flash board. The light-emitting mechanism 200 can be arranged below the passing battery cell 40, and the flash can make the shooting of the size measuring mechanism 160 more accurate, and the light in the light-emitting mechanism 200 makes the feedback of the size of the battery cell 40 clearer.

[0050] In some examples, the loading alignment device 100 also includes a controller (not shown in the figure). The controller is electrically connected to the size measuring mechanism 160 and the adjustment drive mechanism 140. The controller can control the driving action of the adjustment drive mechanism 140 according to the size information obtained by the size measuring mechanism 160. If the size of the battery cell 40 has not changed, there is no need to adjust the drive of the adjustment drive mechanism 140; if the size of the battery cell 40 has changed, the controller controls the adjustment drive mechanism 140 to automatically adjust the relative position of the alignment mechanism and the alignment station 111 online to adapt to the size of the battery cell 40 without stopping for adjustment.

[0051] Optionally, the controller may be, but is not limited to, an industrial computer, a programmable logic controller (PLC), etc.

[0052] In some examples, transport mechanism 110 includes a conveyor belt.

[0053] As shown in FIG. 1 , in some examples, the transmission mechanism 110 includes a first conveyor belt 112, a second conveyor belt 113, and a third conveyor belt 114 that are sequentially arranged. The first conveyor belt 112, the second conveyor belt 113, and the third conveyor belt 114 can be independently controlled. The dimension measuring mechanism 160 is, for example, arranged above the first conveyor belt 112. The light emitting mechanism 200 is, for example, arranged below the first conveyor belt 112. When the battery cell 40 passes through the first conveyor belt 112, its dimension information is acquired by the dimension measuring mechanism 160. Subsequently, the battery cell 40 passes through the second conveyor belt 113 for buffering. The third conveyor belt 114 has an alignment station 111, and the battery cells 40 are aligned one by one on the third conveyor belt 114.

[0054] As shown in FIG4 , in some examples, a position sensor 150 is provided on the transmission mechanism 110 to indicate the alignment station 111 on the transmission mechanism 110. The position sensor 150 is, for example, provided at the third conveyor belt 114. When the position sensor 150 detects the presence of the battery cell 40, indicating that the battery cell 40 has reached the alignment station 111, the transmission mechanism 110 (third conveyor belt 114) stops conveying the battery cell 40. The first alignment mechanism 120 and the second alignment mechanism 130 cooperate to limit the battery cell 40 to the alignment station 111, so that the handling device 310, such as a suction cup, can locate and pick up the battery cell 40.

[0055] In some examples, the adjustment drive mechanism 140 is connected to the first alignment mechanism 120 and the second alignment mechanism 130 to drive the first alignment mechanism 120 and the second alignment mechanism 130 to move closer to or away from the alignment station 111. Further, in some examples, the first alignment mechanism 120 and the second alignment mechanism 130 are driven by different adjustment drive mechanisms 140, respectively.

[0056] As shown in FIG. 1 and FIG. 2 , in some examples, the first alignment mechanism 120 includes a first mounting seat 121 and a plurality of first limiting members 122 distributed on the first mounting seat 121 .

[0057] In some examples, at least part of the first position-limiting member 122 can be raised and lowered on the first mounting seat 121. In some examples, each first position-limiting member 122 can be raised and lowered on the first mounting seat 121. For example, when there is no battery cell 40 on the alignment station 111, the first position-limiting member 122 can be retracted in the receiving hole of the first mounting seat 121 to prevent the first position-limiting member 122 from hindering the movement of the battery cell 40; after the battery cell 40 reaches the alignment station 111, the first position-limiting member 122 extends out of the first mounting seat 121, such as protruding from the upper surface of the first mounting seat 121. At this time, multiple first position-limiting members 122 are arranged around the edge of the battery cell 40 to limit the battery cell 40.

[0058] Similarly, the second alignment mechanism 130 includes a second mounting seat 131 and a plurality of second stoppers 132 distributed on the second mounting seat 131. In some examples, at least some of the second stoppers 132 are movably disposed on the second mounting seat 131. In some examples, each of the second stoppers 132 is movably disposed on the second mounting seat 131.

[0059] As shown in FIG3 , in some examples, the adjustment drive mechanism 140 includes a motor screw transmission assembly. The motor screw transmission assembly can flexibly adjust the distance that the alignment mechanism moves. More specifically, the motor screw transmission assembly includes a drive motor 141, a screw 142, and a ball nut seat (not shown in the figure), the drive motor 141 is connected to the screw 142, the screw 142 cooperates with the ball nut seat, and the ball nut seat is connected to the alignment mechanism. In this way, by driving the screw 142 to rotate by the drive motor 141, the alignment mechanism can be driven to move.

[0060] As shown in FIG. 3 and FIG. 4 , in some examples, the loading alignment device 100 further includes a guide mechanism 180. The alignment mechanism connected to the adjustment drive mechanism 140 is slidably connected to the guide mechanism 180. The guide mechanism 180 is, for example, a slide rail. A slider 190 slidably connected to the guide mechanism 180 may be provided on the guide mechanism 180, and the corresponding alignment mechanism is mounted on the slider 190. The slider 190 is provided with a mounting hole 191 for fastening connection with the alignment mechanism.

[0061] The transfer device 20 of an embodiment of the present invention comprises any of the above-mentioned loading and alignment devices 100 and a handling device 310. The handling device 310 is used to pick up the battery cell 40 on the alignment station 111 and transfer it.

[0062] The transport device 310 may include, but is not limited to, an adsorption device. The transport device 310 may also include a second moving guide rail 320 , on which the adsorption device is disposed and can move along the second moving guide rail 320 , so as to facilitate the transfer of the battery cell 40 .

[0063] The production of heterojunction cells (HJT cells) mainly includes processes such as texturing and cleaning, CVD coating, PVD coating, and screen printing electrodes. The following takes the loading of the cell 40 in the PVD coating process in the HJT cell production process as an example to illustrate the working process of the above-mentioned transfer device 20.

[0064] The cells 40 to be PVD coated are loaded using the loading basket 30, and the loading basket 30 unloads the cells 40 one by one to the first conveyor belt 112. The size measurement mechanism 160 includes a line scan camera arranged on the first conveyor belt 112, and the line scan camera collects the size information of the cells 40 on the first conveyor belt 112, and issues an early warning through the monitored size of the cells 40. A light emitting mechanism 200 is arranged below the first conveyor belt 112, so that the line scan camera can obtain the size information of the cells 40 more accurately.

[0065] The battery cell 40 is then conveyed to the third conveyor belt 114 via the second conveyor belt 113. The third conveyor belt 114 has an alignment station 111. The first alignment mechanism 120 and the second alignment mechanism 130 cooperate to limit the battery cell 40 to the alignment station 111. The adjustment drive mechanism 140 is a motor screw transmission assembly, and the adjustment drive mechanism 140 drives the first alignment mechanism 120 and the second alignment mechanism 130 to approach or move away from the alignment station 111. The controller controls the driving action of the adjustment drive mechanism 140 according to the size information obtained by the size measurement mechanism 160. When the size of the battery cell 40 changes, the relative position of the alignment mechanism and the alignment station 111 is automatically adjusted to adapt to the size of the battery cell 40.

[0066] When the position sensor 150 senses that the cell 40 is transferred to the alignment station 111, the limiting member of the alignment mechanism rises to limit the cell 40. The transport device 310 has a suction cup, which absorbs and lifts the cell 40 after the cell 40 is aligned and transfers it to the screen printing process equipment.

[0067] The above-mentioned loading and aligning device 100 and transfer equipment 20 have the following technical advantages:

[0068] The above-mentioned loading and alignment device 100 and the transfer equipment 20 are respectively provided with a first alignment mechanism 120 and a second alignment mechanism 130 on the opposite sides of the transmission mechanism 110, and an adjusting drive mechanism 140 is provided for driving the corresponding alignment mechanism to be close to or away from the alignment station 111 on the transmission mechanism 110. When the size of the battery cell 40 changes, the alignment mechanism is adjusted by adjusting the driving mechanism 140, which can adapt to the alignment of battery cells 40 of different sizes before loading, avoid the offset and hidden cracking problems of the battery cells 40, and do not need to manually modify the machine, thereby reducing the workload of personnel and improving the stability of the production line and production efficiency.

[0069] Through production practice, using the above-mentioned loading and alignment device 100 and the transfer equipment 20, the deviation rate of the battery cell 40 loading can be reduced to 0.1%, and the proportion of hidden cracks in the battery cell 40 due to uneven adsorption force can be reduced to 0.2%, which effectively improves the production yield of solar cells.

[0070] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
