Detailed Description
Referring to fig. 1, a simplified block diagram of a dye-sensitized solar cell packaging apparatus according to an embodiment of the present invention is shown. The dye-sensitized solar cell packaging apparatus 1 is an automated mechanical apparatus, and includes a feeding unit 10, a first automatic optical detection unit 20, a first cutting unit 30, a film sealing unit 40, a second automatic optical detection unit 50, a second cutting unit 60, a terminal crimping unit 70, a discharging unit 80, and a conveying unit 90.
As shown in fig. 1, the feeding unit 10 is used for inputting a dye-sensitized solar cell semi-finished product (described in detail later). The feeding unit may include a tray 11 and a lifting platform 12. The semi-finished product of the dye-sensitized solar cell is first placed on the tray 11, and then is input to the next work station, for example, the first automatic optical inspection unit 20, via the lifting platform 12.
As shown in fig. 1, the first automatic optical inspection unit 20 may include an inspection lens 21 and an inspection host 22 for inspecting whether the semi-finished product of the dye-sensitized solar cell inputted from the material feeding unit 10 has defects. When the semi-finished product of the dye-sensitized solar cell passes through the detection lens 21, the detection lens 21 takes a picture or a photograph of the semi-finished product and transmits the image to the detection host 22 for analysis. The detection host analyzes the semi-finished product image, and determines which of the semi-finished dye-sensitized solar cells are defective and records the defective dye-sensitized solar cells, such as but not limited to uneven coating of electrolyte, leakage of electrolyte, generation of bubbles, voids, and failure in electrode alignment. Then, the semi-finished product of the dye-sensitized solar cell is fed into the first cutting unit 30.
In one embodiment, the dye-sensitized solar cell packaging apparatus 1 may further include a labeling machine (not shown) for labeling each of the dye-sensitized solar cells before the semi-finished dye-sensitized solar cells are fed into the first cutting unit 30 and cut into individual dye-sensitized solar cells, so as to identify the product lot and record the defective products. However, the position of the labeler according to the present invention is not limited to the above-described embodiment, and may be set at an appropriate position after the first cutting unit 30, and is not particularly limited.
Referring to fig. 1, the first cutting unit 30 may include a cutting blade 31, which may cut the semi-finished product of the dye-sensitized solar cell into a plurality of dye-sensitized solar cells. And then, the cut dye-sensitized solar cell is sent to a film sealing unit 40 for film sealing. If the first automatic optical inspection unit 20 detects a defective product, the defective product can be directly sent to the defective product outlet 32 to be eliminated, so that the subsequent packaging process for the defective product is not required, and the manufacturing cost is reduced.
Referring to fig. 1, the sealing unit 40 is used to attach a protective film on both sides of the cut dye-sensitized solar cell. The protective film is a gas and water resistant film, for example, and can prolong the service life of the dye-sensitized solar cell and be applied to various environments. In the present embodiment, the film sealing unit 40 performs film sealing in a roll-to-roll manner, and may include a lower film sealing machine 410, an upper film sealing machine 420, a dispenser 430, a roller 440, a first UV light source 450, a second UV light source 460, and other components (see fig. 3, which will be described in detail later).
As shown in fig. 1, the dye-sensitized solar cell coated with the protective film by the sealing unit 40 is sequentially fed into the second automatic optical inspection unit 50 and the second cutting unit 60. The second automated optical inspection unit 50 is similar to the first automated optical inspection unit 20, and also has an inspection lens 51 and an inspection host 52 (in another embodiment, the second automated optical inspection unit 50 may share a lens or a host with the first automated optical inspection unit 20). The second automatic optical inspection unit 50 is used to locate the cutting position of the dye-sensitized solar cell, and then cut off the excess protective films (top-sealing film, bottom-sealing film) at the second cutting unit 60. Similar to the first cutting unit 30, the second cutting unit 60 may also include a cutting blade 61.
As shown in fig. 1, the dye-sensitized solar cell whose excess protective film is cut by the cutting blade 61 through the second cutting unit 60 is then fed into the terminal crimping unit 70 to mount the conductive terminals on the dye-sensitized solar cell, thereby completing the dye-sensitized solar cell module. The encapsulated dye-sensitized solar cell module is then fed into the discharging unit 80. The discharging unit 80 may include a tray 81 and a lifting platform 82 for moving the manufactured dye-sensitized solar cell module 1 out of the dye-sensitized solar cell packaging apparatus 1.
As shown in fig. 1, the dye-sensitized solar cell encapsulation apparatus 1 of the present invention further includes a conveying unit 90. The conveying unit 90 is used for conveying the semi-finished dye-sensitized solar cell, the cut dye-sensitized solar cell, or the dye-sensitized solar cell module with the pressed terminal among the units. The conveying unit may include, for example, a robot arm, a bridge crane (commonly called a crown block), and a conveyor belt, wherein the robot arm is used for gripping various objects, such as a semi-finished product of a dye-sensitized solar cell, a cut dye-sensitized solar cell, or a dye-sensitized solar cell module with a crimped terminal. The bridge crane is connected to the robot arm for moving the robot arm to a predetermined position (e.g., at each unit or on a conveyor belt). The conveying unit 90 of the present invention may include more than one set of robot arms and bridge cranes, for example, one set for conveying the semi-finished dye-sensitized solar cell from the feeding unit 10 to the first automatic optical inspection unit 20, and another set for conveying the semi-finished dye-sensitized solar cell from the first automatic optical inspection unit 20 to the first cutting unit 30. In another embodiment, a single set of robots and bridge cranes may be used to transport objects between the units. In other embodiments of the present invention, one or more conveyor belts may be used as the conveying units 90 to transport objects between units.
Referring to fig. 1 in conjunction with fig. 2A and fig. 2B, fig. 2A is a top view of a semi-finished product of a dye-sensitized solar cell according to the present invention; FIG. 2B is a cross-sectional view of a semi-finished product of a dye-sensitized solar cell according to the present invention. The present invention relates to a dye-sensitized solar cell packaging apparatus 1, which is designed for performing secondary packaging on a dye-sensitized solar cell semi-finished product 100 that has been subjected to primary packaging.
As shown in fig. 2A, the semi-finished product 100 of the dye-sensitized solar cell is composed of a plurality of independent dye-sensitized solar cells 101, and can be separated by cutting. In fig. 2A, the dye-sensitized solar cell is rectangular, and 1 semi-finished dye-sensitized solar cell 100 can be cut into 12 dye-sensitized solar cells 101. In other embodiments, the dye-sensitized solar cell 101 may have an irregular shape, and the present invention is not limited thereto. The irregular-shaped dye-sensitized solar cell 101 can be cut out by adjusting the design of the cutting blade 31 (refer to fig. 1) of the first cutting unit 30 in the dye-sensitized solar cell encapsulation apparatus.
Fig. 2B illustrates a cross-sectional view of the dye-sensitized solar cell of fig. 2A along line a-a'. The semi-finished product 100 of the dye-sensitized solar cell is composed of basic structures such as a working electrode 110, a counter electrode 120, a sealant 130, and an electrolyte (not shown in the figure), and is packaged. The semi-finished product 100 of the dye-sensitized solar cell may be provided by another automated packaging device developed by the applicant (described in detail in another application of the applicant), may be made by manually packaging structures such as a working electrode, a counter electrode, a sealant and an electrolyte, or may be made by other automated devices. The manufacturing method of the semi-finished product is not limited, and the semi-finished product conforming to the basic structure of the dye-sensitized solar cell can be packaged for the second time by using the packaging equipment of the dye-sensitized solar cell.
Fig. 3 is a schematic diagram illustrating a film sealing step performed by the film sealing unit 40 of the dye-sensitized solar cell packaging apparatus according to the present invention. The sealing unit 40 is an important work station for secondary packaging, and is used to attach a protective film (a lower sealing film 411 and an upper sealing film 421) to the dye-sensitized solar cell 101. The film sealing method of the film sealing unit 40 is a roll-to-roll (roll) continuous film sealing method, and includes a lower film sealing machine 410, an upper film sealing machine 420, a dispenser 430, a roller 440, and a first UV light source 450. The lower sealing film machine 410 provides a lower sealing film 411, which is coated with a UV glue 431 by a dispenser 430 after removing the lower sealing film protection film 412, and then attached to the bottom side of the dye-sensitized solar cell 101. Meanwhile, the upper sealing film machine 420 provides an upper sealing film 421, after the upper sealing film protection film 422 is removed, the UV glue 431 is also coated by the dispenser 430, and the other side of the dye-sensitized solar cell 101 is attached. Then, the roller 440 presses the dye-sensitized solar cell 101 with the protective films (the lower sealing film 411 and the upper sealing film 421) attached to both sides thereof, so that the lower sealing film 411, the dye-sensitized solar cell 101 and the upper sealing film 421 are better adhered. Finally, the first UV light source 450 irradiates the dye-sensitized solar cell 101, and the UV glue 431 applied to the upper and lower sealing films is cured, so that the lower sealing film 411, the dye-sensitized solar cell 101, and the upper sealing film 421 are tightly adhered to each other, thereby completing the sealing of the dye-sensitized solar cell 101.
In one embodiment, the sealing film unit 40 further includes a second UV light source 460 disposed on the path of only one side sealing film (only the lower sealing film 411) of the dye-sensitized solar cell 101. The second UV light source 460 is, for example, a point light source, and briefly irradiates the dye-sensitized solar cell 101 with a single-sided sealing film, so that part of the UV glue 431 is cured, and the bonding force between the dye-sensitized solar cell 101 and the lower sealing film 411 is strengthened, so that the dye-sensitized solar cell is not easily displaced in the subsequent sealing film process (sealing film attaching, roller pressing, and UV light curing), thereby increasing the production speed and increasing the yield.
Referring to fig. 4, a schematic diagram of the second cutting unit 60 of the dye-sensitized solar cell packaging apparatus 1 according to the present invention is shown. Since the sealing film unit 40 of the present invention performs roll-to-roll continuous sealing film (refer to fig. 3), the dye-sensitized solar cells 101 after sealing are arranged in a long string, as shown in the left side of fig. 4. After the cutting blade 61 of the second cutting unit 60 positions the cutting position via the second optical detection unit 50 (refer to fig. 1), the excess lower sealing film 411 and the excess upper sealing film 421 are cut off, leaving the independent dye-sensitized solar cell 101.
Referring to fig. 5, a schematic diagram of a terminal crimping unit 70 of the dye-sensitized solar cell packaging apparatus 1 according to the present invention is shown. The terminal crimping unit 70 has a crimping device 71 for crimping the conductive terminals 72 and the dye-sensitized solar cell 101 by gravity when the dye-sensitized solar cell 101 passes through, thereby completing the dye-sensitized solar cell module 102.
The dye-sensitized solar cell packaging equipment provided by the invention carries out secondary packaging on the semi-finished product of the dye-sensitized solar cell with the basic structure by using an automatic machine, and has the advantages of convenience in operation, fast flow and labor saving. After the semi-finished product of the dye-sensitized solar cell is cut, sealed and pressed into terminals to manufacture a plurality of independent dye-sensitized solar cell modules, the service life of the original dye-sensitized solar cell can be prolonged, and the dye-sensitized solar cell module can be applied to various different environments. In addition, in the process of carrying out secondary packaging by the dye-sensitized solar cell packaging equipment, defective products can be detected, and the defective products are removed in advance, so that the production yield is improved, and the cost increase caused by extra packaging of the defective products is avoided.
Fig. 6 is a flow chart illustrating a method for encapsulating a dye-sensitized solar cell according to an embodiment of the invention. The above dye-sensitized solar cell encapsulation apparatus may perform the encapsulation method, which includes the following steps S01 to S04:
s01: providing a semi-finished product of the dye-sensitized solar cell:
fig. 2A and 2B are schematic views of a dye-sensitized solar cell semi-finished product. The semi-finished product 100 of the dye-sensitized solar cell is prepared by coating a sealant 130 and an electrolyte (not shown) on the working electrode 110 and the counter electrode 120, and then performing a basic packaging step to seal the electrodes. In addition, the semi-finished product 100 of the dye-sensitized solar cell includes a plurality of independent dye-sensitized solar cells 101, and each of the dye-sensitized solar cells 101 can be independently operated to provide a voltage.
S02 cutting: cutting the semi-finished product of the dye-sensitized solar cell into a plurality of dye-sensitized solar cells:
as shown in fig. 2A, the semi-finished product 100 of the dye-sensitized solar cell includes a plurality of individual dye-sensitized solar cells 101, and the trimming step is to cut and separate the individual dye-sensitized solar cells 101 from the semi-finished product. It is particularly noted that although each individual dye-sensitized solar cell 101 in fig. 2A has a rectangular shape, the individual dye-sensitized solar cells may have an irregular shape in practical applications, and the present invention is not limited thereto.
S03 film sealing: pasting a protective film on the two sides of the cut dye-sensitized solar cell:
referring to fig. 3, a schematic diagram of the film sealing unit 40 of the dye-sensitized solar cell packaging apparatus according to the present invention is shown when performing a film sealing step. The film sealing step is a roll-to-roll (roll) continuous film sealing, in which a lower sealing film 411 is provided by a lower sealing film machine 410, after the lower sealing film 411 removes a lower sealing film protection film 412, a UV glue 431 is coated by a dispenser 430, and then the bottom side of the dye-sensitized solar cell 101 is attached. At this time, the second UV light source 460 may briefly irradiate the dye-sensitized solar cell 101 only covered on one side, so that part of the UV glue 431 is cured, and the bonding force between the dye-sensitized solar cell 101 and the lower cover film 411 is strengthened. Next, an upper sealing film 421 is provided by the upper sealing film machine 420, and after the upper sealing film 421 is removed from the upper sealing film protection film 422, the UV glue 431 is applied by the dispenser 430, and the other side (top side) of the dye-sensitized solar cell 101 is attached. Then, the roller 440 presses the dye-sensitized solar cell 101 with the protective films (the lower sealing film 411 and the upper sealing film 421) attached to both sides thereof, so that the lower sealing film 411, the dye-sensitized solar cell 101 and the upper sealing film 421 are better adhered. Finally, the first UV light source 450 irradiates the dye-sensitized solar cell 101, and the UV glue 431 coated on the upper and lower sealing films is cured to closely adhere the lower sealing film 411, the dye-sensitized solar cell 101, and the upper sealing film 421, thereby completing the step of sealing the dye-sensitized solar cell 101.
Referring to fig. 4, since the step of sealing at S03 is a roll-to-roll continuous sealing, the dye-sensitized solar cells 101 after sealing are arranged in a long string (as shown in the left side of fig. 4), and have an excess of the lower sealing film 411 and the upper sealing film 421. Therefore, after the sealing, the cutting positions of the upper and lower sealing films can be located by an automatic optical detection system, and then the excess lower sealing film 411 and the excess upper sealing film 421 are cut off, leaving the independent dye-sensitized solar cell 101.
S04 crimp terminal: and (3) pressing and connecting the conductive terminals on the dye-sensitized solar cell with the protective film to complete the dye-sensitized solar cell module:
fig. 5 is a schematic diagram illustrating the terminal crimping unit 70 of the dye-sensitized solar cell packaging apparatus 1 of the present invention performing the terminal crimping sub-step. The terminal crimping unit 70 has a crimping device 71 for crimping the conductive terminals 72 and the dye-sensitized solar cell 101 by gravity when the dye-sensitized solar cell 101 passes through, thereby forming a dye-sensitized solar cell module 102.
In another embodiment, before the step of cutting at S02, an automatic optical inspection system may be used to detect whether the semi-finished product of the dye-sensitized solar cell has defects, and after the step of cutting at S02, the defective dye-sensitized solar cell is removed.
The secondary encapsulation of the dye-sensitized solar cell can be simply and rapidly completed by the dye-sensitized solar cell encapsulation device (or the dye-sensitized solar cell encapsulation method S01-S04), and the semi-finished dye-sensitized solar cell can be manufactured into a dye-sensitized solar cell module with commercial value. Because most steps are carried out by automatic equipment, the yield is obviously increased, the error of each step can be reduced, the yield is increased, and the labor cost can be saved.
Although the present invention has been described with reference to the above embodiments, the above embodiments are merely illustrative, and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications to the disclosed aspects of the embodiments. Therefore, the protection scope of the present invention shall be subject to the claims of the present invention.
