Operation afterwards can carry out the operation that the arrangement gone here and there and packaging machine carry out packing.
The specific embodiment method for joining electrode to the solar battery cell of the present invention as above will be enumerated below be explained in more detail. Below, it will quote the drawing symbol in each portion of the electrode engagement device of the solar battery cell of the present invention of described above.
First, as shown in S71 step and Fig. 8 of Fig. 7, in conducting film supply unit 10, bond after cutting off conducting film 2 to the main line electrode respectively of multiple solar battery cells 5,6,7. Described conducting film 2 is the state being attached with release paper, but by the separated part 14 of conducting film supply unit 10 as described above with select cutting portion 20, can by separate the conducting film 2 of release paper carry out cutting off with specific length be attached to the above of described solar battery cell 5,6,7 with on the main line electrode of bottom surface.
Afterwards, as shown in S72 step and Fig. 9, cut off while making the two ends phase ground connection being attached to the conducting film 2 of the above and bottom surface being attached to solar battery cell 6 of the above conducting film 2 of described solar battery cell 5 be loaded with 8, make the two ends phase ground connection of the above conducting film 2 and the conducting film 2 of the bottom surface being attached to solar battery cell 7 that are attached to described solar battery cell 6 be loaded.
As it has been described above, can series-connected solar cells unit 5,6,7 by alternately connecting the above and bottom surface of solar battery cell 5,6,7. In order to so load band 8, after needing cut-out band 8, after derivation, it is necessary to regulate the transfer of solar battery cell, specific solar battery cell is loaded into this top with 8, makes the conducting film 2 being attached to the bottom surface of solar battery cell be contacted with above 8.
Afterwards, as shown in step S73 and Figure 10, use described pre-junction surface 40, carry out matching the pre-of state with 8 with conducting film 2 engage described. Now, as described above, using loaded pins 43 only to apply pressure makes band 8 engage in advance with conducting film 2.
Pressure now is preferably 0.6 ± 0.02Mpa. During more than 0.08Mpa, solar battery cell 6 likely can fragmentation, during less than 0.04Mpa, will be unable to be formed and the bonding of conducting film 2.
Afterwards, as shown in S74 and Figure 11, after the solar battery cell of the state of pre-terminated crossed belt 8 and conducting film 2 is transplanted on bonding station in described pre-junction surface 40, applies heat and makes band 8 and conducting film 2 be fully engaged with pressure.
Now, described bonding station, such as the example at described first to the 3rd junction surface 60,70,80, it is possible to for possessing for multiple junction surfaces, and by each junction surface, band 8 can be fully engaged by thermo-compressed with conducting film 2. Now being preferably, junction temperature is 180 ± 5 DEG C, activating pressure is 0.28 ± 0.02Mpa, and the bonding process time is preferably 10 ± 1 seconds.
When described junction temperature is more than 185 DEG C, the polymerizable degree of conducting film 2 too causes conducting film 2 flow phenomenon, during less than 175 DEG C, it is possible to do not engage.
As it has been described above, when described engaging time was more than 11 seconds, conducting film 2 flow phenomenon can be there is because of overheated causing, during less than 9 seconds, it is possible to do not occur successfully to engage.
In addition, activating pressure is less than the pressure of above-mentioned pre-joint, therefore it is absent from occurring the misgivings of solar battery cell 6 disrepair phenomenon, when but activating pressure is more than 0.3Mpa, can because pressure and thermal conductance cause the situation generation that conducting film 2 starts to side, during less than 0.26Mpa, can cause because engagement state does not become the state touched completely that resistance becomes big. The increase of this resistance can be directly connected to the efficiency of solar battery cell module, and becomes the reason lowered efficiency.
As described above, the time consumed as the S74 step of engagement step is longer than the time that other steps consume, therefore engage to the solar battery cell 5,6,7 of multiple junction surfaces transfer band 8 with the pre-engagement state of conducting film 2, such that it is able to the stand-by time shortening each step promotes productivity more.
As mentioned above, the preferred embodiments of the present invention have been explained, but the present invention is not limited to above-described embodiment, various deformation enforcement can be carried out in technical scope with the detailed description of invention and the scope of accompanying drawing, and this deformation implementation falls within the scope of the invention.
