Description

Technical Field

[0001] The present invention relates to the technical field of solar cell assembly production methods, and in particular to a solar cell assembly production system and a solar cell assembly production method. Background Art

[0002] BC (Back Contact) cells, or back contact cells, are a general term for all types of crystalline silicon solar cells with back contact structures. Both the emitter electrode and the base electrode are located on the back, so the shading loss of the front grid line can be eliminated and the cell efficiency can be improved. They are considered to be the mainstream products of crystalline silicon cells in the future. Since the positive and negative poles of BC cells are located on the same side, only one side of the cell needs to be welded when welding the BC cells. However, since the heat is concentrated on one side of the cell, a large thermal stress will be generated on that side. Therefore, after welding, the BC cells are prone to warping. The warped cell panels are prone to misalignment, solder joint detachment, cell displacement and other risks during the subsequent positioning, swinging, busbar welding, transfer, lamination and other processes. In addition, most existing cell production lines use conveyor belts to transfer cells. After the string welding, the solder strips at both ends of the cell string are prone to bend when passing through the joint of the conveyor belt, thereby affecting the cell yield. Although some existing battery production lines straighten battery cells by adding pressure plates and pressure nets, this straightening method cannot guarantee that the battery cells remain flat throughout the entire process. After transferring workstations or being transported on different conveyor belts, the battery cells need to be straightened repeatedly. Repeated bending of battery cells increases the risk of hidden cracks and fragments, thereby affecting the battery yield. Summary of the invention

[0013] As an improvement of the above solution, the transport assembly further includes a second track, the second mobile platform is connected to the second track, and the second mobile platform can move along the second track.

[0014] As an improvement of the above solution, the lamination station is provided with a back plate, and a connecting film is provided on the surface of the back plate. The conveying assembly is used to transfer the battery string to the lamination station and place the battery string on the connecting film so that the connecting film is bonded to the battery string.

[0015] As an improvement of the above solution, the transport assembly also includes a heating mechanism, which is arranged in the second mobile platform. The heating mechanism includes a heating element, and the heat transfer portion of the heating element is used to abut against the battery string and transfer heat to the connecting film through the battery string.

[0016] As an improvement of the above solution, the second adsorption mechanism is further used to release the battery string after the connection film and the battery string are bonded for a preset period of time.

[0017] As an improvement of the above-mentioned solution, the heating mechanism also includes an elastic member, one end of which is connected to the second movable platform, and the other end is connected to the heating member, the heat transfer portion of the heating member protrudes from the surface of the second adsorption surface, and when the heat transfer portion of the heating member abuts against the battery, the elastic member is compressed.

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0037] See also Figure 1 and Figure 2The embodiment of the present invention discloses a solar cell assembly production system for operating, welding and arranging a battery 10. The solar cell assembly production system includes a moving assembly 1, a welding assembly 2 and a transport assembly 3. Before welding, a cell 9 is placed on the moving assembly 1. The cell 9 is preferably a back contact cell. The emitter electrode and the base electrode of the back contact cell are both located on the back. The electrodes can be welded on the same side of the cell 9. The cell 9 can be arranged by a plurality of cells. The moving assembly 1 can drive the cell 9 to move to the welding station 6, and the cell 9 is welded by the welding assembly 2. Among them, the moving assembly 1 includes a first moving platform 11 and a first adsorption mechanism 12. The first adsorption mechanism 12 can adsorb a plurality of the cell 9 on the first moving platform 11. By adsorbing one or more positions of the cell 9, the cell 9 can be abutted against the first moving platform 11, so that the cell 9 can be flattened before welding. Exemplarily, the number of the first moving platforms 11 is multiple. The first mobile platform 11 can move between different stations. Before welding the battery cell 9, the first mobile platform 11 brings the plurality of battery cells 9 to the welding station 6. During the movement, the first adsorption mechanism 12 can maintain the adsorption of the battery cell 9, and the welding assembly 2 can weld the battery cell 9 on the first mobile platform 11 to form a battery string 10 by welding the plurality of battery cells 9 in series. During the welding process, the first adsorption mechanism 12 will maintain the adsorption of the battery cell 9 so that the battery cell 9 can continue to remain flat before and during welding. The transport assembly 3 includes a second mobile platform 31 and a second adsorption mechanism 32. The second adsorption mechanism 32 is used to adsorb the battery string 10 to the second mobile platform 31 when the first adsorption mechanism 12 adsorbs the battery string 10. The second mobile platform 31 can move the battery string 10 out of the first mobile platform 11 and move the battery string 10 to the lamination station 7 (which can also be a typesetting station). During the process of removing the battery string 10, the second adsorption mechanism 32 can continuously adsorb the battery string 10, so as to keep multiple positions of the battery string 10 flat. Therefore, before, during and after welding, the battery string 10 can be continuously flat and warping can be avoided.

[0038] The beneficial effects of the embodiments of the present invention are as follows:

[0039] The solar cell assembly production system of the embodiment of the present invention is provided with a moving assembly 1, a welding assembly 2 and a conveying assembly 3. Before welding the cell 9, the cell 9 is placed on the first moving platform 11 of the moving assembly 1, and the cell 9 is adsorbed on the first moving platform 11 by the first adsorption mechanism 12. Therefore, before welding, the cell 9 can remain flat on the first moving platform 11. When the welding assembly 2 welds the cell 9, the first adsorption mechanism 12 maintains the adsorption of the cell 9. Therefore, during welding, the cell 9 can remain flat. After welding, the second adsorption mechanism 32 of the conveying assembly 3 adsorbs the welded cell string 10 on the second moving platform 31, and the second moving platform 31 transfers the cell string 10 out. In this process, the second adsorption mechanism 32 can continuously adsorb the cell string 10 on the surface of the second moving platform 31. Therefore, after welding, the cell string 10 can remain flat, so that the cell string 10 can continue to remain flat before and after welding, and warping can be avoided without repeated straightening. Furthermore, when the battery string 10 moves between the moving assembly 1 and the transport assembly 3, the welding strip will not fall into the connection of the conveyor belt, and the battery string 10 can remain flat throughout the whole process. Therefore, the welding strip will not be bent, thereby improving the yield rate of the battery string 10 production.

[0040] Specifically, see Figure 2 , the first adsorption mechanism 12 includes a first suction hole 121, and the first suction hole 121 is arranged on the first movable platform 11. The number of the first suction holes 121 is multiple, and they are evenly distributed on the first movable platform 11, and can adsorb and fix multiple parts of the battery cell 9. The first suction hole 121 can adsorb the battery cell 9 on the first movable platform 11, on the one hand to maintain the continuous fixation of the battery cell 9, and on the other hand to avoid subsequent welding and warping after welding. The first adsorption mechanism 12 also includes a first channel 122 and a negative pressure generating part 123, and the negative pressure generating part 123 is connected to the first suction hole 121 through the first channel 122. The negative pressure generating part 123 is preferably a vacuum pump, which can generate negative pressure to the first suction hole 121 through the first channel 122.

[0041] Furthermore, the moving component 1 also includes a first adsorption surface 13 and a first track 14, the first adsorption surface 13 is provided on the upper surface of the first moving platform 11, the battery cell 9 is placed on the first adsorption surface 13, and the first suction hole 121 is provided on the first adsorption surface 13, which can directly produce an adsorption effect on the battery cell 9. The first moving platform 11 can move along the first track 14, and the first track 14 extends from the swing piece station 5 to the lower string station 8. After the battery cell 9 passes through the swing piece, it is moved from the swing piece station 5 to the welding station 6 by the first moving platform 11 along the first track 14. Different from the traditional conveyor belt conveyor, the first moving platform 11 can move as a whole, and the battery cell 9 moves with the first moving platform 11. Before the welding is completed, the battery cell 9 does not leave the first moving platform 11, thereby ensuring that the first moving platform 11 can continue to adsorb and fix the battery cell 9.

[0042] See also Figure 3 and Figure 4 , the second moving platform 31 adsorbs the battery string 10 transferred to the lower string station 8 after welding from top to bottom. The lower surface of the second moving platform 31 is provided with a second adsorption surface 33, and the second adsorption mechanism 32 includes a second suction hole 321, and the second suction hole 321 is provided on the second adsorption surface 33, and the second suction hole 321 can adsorb the battery string 10 on the second adsorption surface 33. After the battery cell 9 is welded, the first moving platform 11 brings the battery string 10 to the lower string station 8. During this process, the second adsorption mechanism 32 maintains the adsorption of the battery string 10, so that the battery string 10 can still be affected by the adsorption force after welding and abut against the second adsorption surface 33. The second adsorption mechanism 32 plays a role in keeping the battery string 10 continuously flat.

[0043] The second adsorption mechanism 32 further includes a second channel 322 and a negative pressure system 323, and the negative pressure system 323 is connected to the second suction hole 321 through the second channel 322. The negative pressure system 323 is preferably a system having a vacuum pump and a regulating valve, which can generate negative pressure on the second suction hole 321 through the second channel 322, thereby forming an adsorption force.

[0044] The transport assembly 3 further includes a second track 34, and the second moving platform 31 is connected to the second track 34. The second track 34 extends from the welding station 6 to the lamination station 7, and the second moving platform 31 can move along the second track 34 to take the battery string 10 away from the welding station 6.

[0045] The solar cell assembly production system also includes a laminating station 7, on which a backplane 4 is provided. The backplane 4 is preferably a glass backplane 4, which needs to be attached to the battery string 10 to form a preliminary assembly. A connecting film 41 is provided on the surface of the backplane 4. The connecting film 41 is preferably an EVA adhesive film, which can be melted after heating. The connecting film 41 is located on the upper surface of the backplane 4, and the handling assembly 3 can transfer the battery string 10 entering the lower string station 8 after welding to the laminating station 7, and place the battery string 10 on the connecting film 41, so that the battery string 10 is bonded to the connecting film 41. Optionally, after placing the battery string 10 on the connecting film 41, the second adsorption mechanism 32 can maintain the adsorption and fixation of the battery string 10, and press the battery string 10 to a certain extent, so that the bonding between the battery string 10 and the connecting film 41 is more firm.

[0046] Among them, in other embodiments, see Figure 3 and Figure 4 As a method of heating the connecting film 41, the transport assembly 3 further includes a heating mechanism 35, which is disposed in the second moving platform 31. The heating mechanism 35 includes a heating element 351, and the heat transfer portion of the heating element 351 can abut against the battery string 10. After the heating element 351 is turned on, the heat generated by the heating element 351 is transferred to the battery string 10 through the heat transfer portion, and the heating element 351 can transfer the heat to the connecting film 41 through the battery string 10, so that the connection between the connecting film 41 and the battery string 10 is melted. The connecting film 41 is heated to produce a certain degree of melting (or micro-melting), so that the connecting film 41 is bonded to the battery string 10. Under the action of the connecting film 41, each position of the battery string 10 can be attached to the connecting film 41, forming a flat and non-warping effect, so that during typesetting, even if the transport assembly 3 is removed, the battery string 10 can still be kept flat.

[0047] During the process of the heating mechanism 35 heating the connecting film 41, the second adsorption mechanism 32 maintains the adsorption and fixation of the battery string 10. Optionally, after the connecting film 41 and the battery string 10 are bonded for a preset time, the second adsorption mechanism 32 releases the battery string 10 to ensure the heating time and heating effect.

[0048] Furthermore, in some embodiments, the heating mechanism 35 further includes an elastic member 352, one end of which is connected to the second moving platform 31, and the other end of which is connected to the heating member 351. The heat transfer portion of the heating member 351 protrudes from the surface of the second adsorption surface 33, and when the heat transfer portion of the heating member 351 abuts against the battery string 10, the elastic member 352 is compressed. The elastic member 352 can make each battery cell in the battery string adsorbed on the second adsorption surface, and can ensure that the heat transfer portion of the heating member 351 can abut against the battery string 10, thereby improving the heating effect of the connecting film 41.

[0049] It is understandable that the connecting film 41 may also be heated in other ways, for example, a heating device is provided at the lamination station 7 to heat the connecting film 41 .

[0050] See also Figure 5 The embodiment of the present invention further discloses a method for producing a solar cell module, which is applied to the solar cell module production system as described above to produce a cell sheet 9, and comprises the following steps:

[0051] S01, placing the battery cell 9 on the first movable table 11, the first movable table 11 transports the battery cell 9 to the welding station 6 along the first track 14, during which the battery cell 9 is adsorbed on the first movable table 11 by the first adsorption mechanism 12 of the movable component 1.

[0052] S02, then the welding component 2 welds the battery cells 9 to form a battery string 10, and after welding is completed, the second adsorption mechanism 32 of the conveying component 3 adsorbs the battery string 10 onto the second mobile table 31, and the second mobile table 31 moves the battery string 10 from the first mobile table 11 to the lamination station 7.

[0053] The battery cell 9 is placed on the first movable platform 11 for swinging. After the swinging is completed, the first adsorption mechanism 12 of the movable component 1 adsorbs the battery cell 9 on the first movable platform 11 to produce an adsorption and fixing effect on the battery cell 9, and at the same time ensures that the battery cell 9 can remain flat before welding.

[0054] It should be noted that the first moving platform 11 can move directly on the first track 14, and can maintain the adsorption and fixation of the battery cell 9 before and after welding. Compared with the traditional process of conveying the battery cell 9 for welding by a conveyor belt, the battery cell 9 of the embodiment of the present invention does not need to be transferred on different conveyor belts, thereby ensuring that the battery cell 9 is continuously adsorbed and fixed on the same first moving platform 11 before welding, thereby avoiding repeated warping of the battery cell 9 during the transfer process.

[0055] In addition, the following steps are included:

[0056] S03 , when the welding assembly 2 welds the battery cells 9 to form the battery string 10 , the first adsorption mechanism 12 keeps adsorbing the battery cells 9 on the first moving platform 11 .

[0057] S04 , after the second adsorption mechanism 32 adsorbs the battery string 10 onto the second moving platform 31 , the first adsorption mechanism 12 releases the battery string 10 .

[0058] During welding, the first adsorption mechanism 12 still maintains adsorption on the battery cell 9, so that the welding stress generated on the surface of the battery cell 9 during welding can be offset by the adsorption force of the first adsorption mechanism 12, thereby preventing the battery cell 9 from warping during welding.

[0059] After welding is completed, a station can be added to facilitate the handling assembly 3 to move the battery string 10. The conventional station after the welding station 6 is the lower string station 8. After welding is completed, the first moving platform 11 brings the battery string 10 to the lower string station 8, and the handling assembly 3 moves the battery string 10 out of the lower string station 8. During the process of the first moving platform 11 moving from the welding station 6 to the lower string station 8, the first adsorption mechanism 12 maintains adsorption of the battery string 10.

[0060] When removing the battery, after the second moving platform 31 abuts against the surface of the battery string 10, the second adsorption mechanism 32 starts adsorption of the battery string 10, and then the first adsorption mechanism 12 disconnects the adsorption of the battery string 10 to release the battery string 10. At this time, the second adsorption mechanism 32 replaces the first adsorption mechanism 12 to continuously adsorb and fix the battery string 10 and to continuously keep it flat. In this process, the second adsorption mechanism 32 can achieve better connection to ensure that the battery string 10 is in an adsorption state that offsets the warping effect after welding. Therefore, the battery string 10 can remain flat before, during and after welding to avoid warping.

[0061] In addition, after the welding is completed, the solar cell assembly production method further comprises the following steps:

[0062] S05 , the second movable table 31 transfers the battery string 10 to the lamination station 7 along the second track 34 . After the second movable table 31 places the battery string 10 on the connection film 41 of the back plate 4 , the second movable table 31 maintains contact with the battery string 10 .

[0063] S06 , the heating mechanism 35 of the transport assembly 3 then heats the battery string 10 , and the heat is transferred to the connecting film 41 to melt the connecting film 41 , and the connecting film 41 is bonded to the battery string 10 .

[0064] In the lamination station 7, the battery string 10 that has been welded is arranged and connected to the back plate 4. During the process of the second mobile station 31 transferring the battery string 10 from the welding station 6 to the lamination station 7 (or from the lower string station 8 to the lamination station 7), and after the second mobile station 31 places the battery string 10 on the connection film 41 of the back plate 4, the second adsorption mechanism 32 continues to adsorb the battery string 10 on the second mobile station 31. After the battery string 10 is placed on the connection film 41 on the back plate 4, the second mobile station 31 applies pressure to the battery string 10 so that the second mobile station 31 maintains contact with the battery string 10.

[0065] While the second movable platform 31 maintains contact with the battery string 10, the heating mechanism 35 of the conveying assembly 3 heats the battery string 10, and the heat is transferred to the connecting film 41 through the battery string 10, causing the surface of the connecting film 41 to melt slightly and then adhere to the battery string 10. The connecting film 41 forms a new fixing effect on the battery string 10, after which the second adsorption mechanism 32 is closed, and the second movable platform 31 is separated from the battery string 10. The connecting film 41 can keep the battery string 10 flat, so that the battery string 10 can be flattened uninterruptedly throughout the swinging, welding and layout processes, and the warping of the battery string 10 can be avoided. In addition, the first adsorption mechanism 12, the second adsorption mechanism 32 and the connecting film 41 can be connected continuously throughout the whole process. In addition, compared with the traditional conveyor belt transportation method, the battery string 10 in the embodiment of the present invention does not need to switch between multiple conveyor belts, so there is no need to straighten repeatedly during switching, and no additional fixed limit method is required, and the welding belt can be prevented from bending at the connection point of the conveyor belt. Therefore, the embodiment of the present invention can ensure that the battery string 10 is flat and warp-free, and can greatly improve the production yield of the battery string 10.

[0066] In addition, the following steps are included:

[0067] After the connection film 41 and the battery string 10 are bonded for a preset time, the second adsorption mechanism 32 releases the battery string 10 .

[0068] When the heating mechanism 35 heats the connecting film 41, the second adsorption mechanism 32 keeps adsorbing and fixing the battery string 10. After the connecting film 41 and the battery string 10 are bonded for a preset time, the second adsorption mechanism 32 releases the battery string 10 to ensure the heating time and heating effect.

[0069] The above are preferred embodiments of the present invention. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
