Description

Positive battery

Art field

The present invention relates to an apparatus for inspecting the general performance of a solar cell, such as a solar cell, a string in which solar cells are connected in a row, and a solar cell in which a plurality of strings are arranged in parallel.

As a method of using leeks, a linear solar cell is known. In the production of positive cells, the value of solar cells having the desired power is important.

The output is usually determined by the value.

It is performed as photoelectricity to measure the current voltage of the solar cell in the light irradiation. As expected, solar light is desirable, but because the intensity changes according to the weather, a solar is used. In the solar system, a xeno lamp or a metallized lamp is used instead of sunlight. If these lights are turned on for a long time, the amount will change due to temperature rise. Therefore, by using the lamps of these lamps, the horizontal axis represents voltage and current, and the collected data is put to obtain the solar cell lines (Patent).

As a different method, Patent 2 proposes a method of generating a Kutonescence () by applying a voltage in the direction toward the positive cell of the silicon. The same thing happens with the positive battery. By observing the light emitted from the positive battery, the current distribution can be determined, and the solar cell can be known from the average current distribution. In other words, it can be determined that the portion that does not emit light is a defective portion, and if the product of this portion is less than expected, it can be determined that it has a predetermined force.

FIG. 2 is a diagram schematically showing the configuration of the inspection apparatus described in Patent 2.

Mysterious Issues to be addressed

0, shown in 2 and the solar cell 3 is placed underneath and taken by the camera from above. The light emitted from the solar cell 3 is weak light of, 000, 300, and is in a dark room. I can't know without it. In the case of a single solar cell, it is about 0, so the darkroom is small.

However, when it comes to solar cells, it is 2 x degrees, and the darkroom must be large enough to accommodate it. In addition, the positive battery must be placed in the dark room and cannot be photographed by the CC camera 2. Therefore, it is necessary to provide a door in the dark room where the solar battery can be inserted. If the installed door is closed, it must be ensured that it can be carried into this room. In addition, it is necessary to install it in the stamping material and guide darkroom for the solar cells carried into the inspection device. Furthermore, it is necessary to install it in a dark room for passing current through the solar cell. In addition, it becomes structurally complicated and expensive.

The purpose of the present invention is to provide a solar cell with a simple structure and a low cost, which is a test device that allows a forward current to flow through a solar cell to emit light.

To solve

In order to achieve the above objective, a bright positive cell, a dark room having an opening on the upper surface, a stage provided on the upper surface of the chamber, and a stage for holding the positive cell on the mouth, are provided in the chamber. And a camera for photographing the image.

In addition, the camera may be provided with a moving mechanism that moves the camera provided in the room in the room.

In addition, a step for blocking indoor light from the boundary between the mouth and the positive battery held on the mouth is provided, or the positive battery is sent to the upper surface. A structure provided with a step can be used.

Further, a reflection that is inclined with respect to the mouth portion may be provided in the room, and an image of an object projected on the camera may be taken.

Mysterious

In the case of a bright positive battery, the camera in the dark room can take an image of the solar battery if the positive battery covered on the mouth of the room surface is supported from the dark room side. In the case where a current flows through the solar cell, the solar cell emits light. To capture this state with a camera and analyze it with an image processing device connected to the camera, You can know the safety of the positive battery. Since the light emitted from the positive battery is weak, if a glass synthetic resin or the like is used to place the solar battery in the opening and the camera is used to shoot through it, 50 solar light from the solar battery will be collected and attenuated. . However, in the light, the solar cell is on the opening, the solar cell is exposed in the opening, and can be obtained with a camera that does not attenuate light emission with a transparent plate or the like. This feature is particularly advantageous when measuring positive cells.

The positive battery can be inspected by placing it on the surface of the room from outside the dark room, and it is not necessary to provide a door for taking the positive battery into and out of the dark room. As a result, the darkroom can be miniaturized and the construction can be simplified.

Furthermore, in the case of solar cells, they are sent face down on the production line (such as a net device). Therefore, the solar cell can be placed on a device that is not inverted by constructing the light device with an opening on the upper surface of the dark room. In addition to this, the room can be made even smaller by providing a slanted reflection with respect to the opening and photographing the image on the opening with a camera.

(Positive battery)

First, let's take the example of 20 where Akira is an elephant. (A) is a front view showing that the positive battery cell of the solar cell part is known, and (b) is a front view thereof.

As shown in the side view of a, the positive battery cell 200 is formed of a string 25 in which a positive battery cell 28 is connected to a plurality of columns by a lead 29, and the string is further divided into a number string 29. It is a connected configuration.

As for the positive cell which is 200, it is possible to use only one solar battery cell 28, or several solar battery cells 28 in a string 25 state where the string 25 is arranged linearly. Solar cells with battery cells arranged in a tox shape can also be used. As shown in the figure, the solar cell 30 has a blank space 30 such as a solar cell 28 on it.

In addition, as shown in (b), the plane structure of 200 has a structure in which a plurality of strings 25 are sandwiched between the glass plates 2 arranged in 2 2 through the filling 23. Have.

For example, materials such as polyurethane are used. 23 24 (Polyvinyl 1 or the like is used. The string 25 has a configuration in which the solar cell 28 is connected between the electrodes 26 via the lid 29 as described above.

Such a solar battery can be obtained by applying a pressure by applying a vacuum by applying a vacuum by using a laminated netting or the like as described above, and applying a net.

In addition, 20 can be a positive battery generally called a thin film.

In this tabular structure, the crows placed in the

A power generation element consisting of a semiconductor and a back electrode is attached. Then, the solar cell is placed in the same way with a transparent glass plate facing downward, filled on the solar cell on the glass, and backed on the filler. Is obtained.

Thus, it is the same as in the case of the basic crystal cell described above, except that it is changed to a power generation element to which the positive cell as 200 is attached.

Figure (c) is a right side view. 2 is a diagram of the dark room part (a) is a diagram in which the upper part of the dark room is the opening part 2, and (b) is a diagram in which the upper part is the opening part 2. 3 is a diagram showing the configuration of the camera device of the solar cell, where a is a plan view, (b) is a side view, and (c) is a right side view. The clear positive cell shown in these figures has a square 0 and such an opening 2. As shown in 2 a, the mouth 2 is formed on the dark surface in consideration of the size of 20. In the room, there is a camera 20 for inspecting the positive battery, which is 200, and its moving mechanism. However, the moving mechanism of the camera 20 may not be provided depending on the way. Mouth 2 Outlet, dark room 0 is made of a material that does not allow light to enter. Alternatively, after the solar cell is mounted as 200 on the upper surface, the body including the covered member 200 is removed in steps, and the upper body may be the opening 2 as shown in 2). In addition, the 4 surfaces outside the top surface and the bottom surface are all sexual. A pair of guides 4 for guiding the feeding of 200 is provided. The distance between the guides 4 can be changed according to the size of 20.

3 guides and

Guide 4 is the length of the surface, and it faces the clear 0 surface along the direction of 200 degrees. A plurality of 5s are arranged on the surface of the guide 4, and the 2 is moved and sent over this. Guide 4 A plurality of 5 forms a stage for holding the solar cell 30 on the opening. Therefore, 20 is not being dropped into the opening 2 from the opening 2 during the sending of 200 and the filing. This guide 4 is also used in the movement of the device located at 200 and

6 、 Send 7 、 and 8 can be adjusted according to the 200 method. In other words, the feed 7, one on the right and the other on the left, rotates the guide 8 so that the guides 4 and 4 are close to each other with the center position fixed. . And and

Is connected by a box 3 equipped with a car, and by rotating the door 8, both T can be rotated simultaneously by the car.

On the surface of the guide 4 there is a metal fitting that can be inserted and removed by an actuator or the like, and the sent 200 is directed to project the metal fitting 9 for this purpose. The metal fitting 9 can be constructed such that the guide 4 is placed in and out of the guide 4 and can be moved up and down from the guide 4 or lowered from the guide material. Metal fitting 9

<4 Camera

It is a weak light of 3,000,000 emitted from 20 and is emitted in a dark room, and this weak light is photographed by the camera 20. For this reason, it is necessary to use a CC camera with sensitivity to weak light as the camera 20. In the implementation, Hamamatsu Tox type C9299 2 CC Mera) is used.

5 Indoor camera movement mechanism

Figure 3 shows the structure of the camera movement mechanism. Within 0, there are camera 2 and guide 3 that moves this camera 20 in the direction. At the end of the guide 30, there is a motor 32, which can be rotated to move the camera 20 forward and backward.

The guide 30 is supported by the guide 400. The guides 3 can be advanced and retracted in the direction along the guide by the timing 44 on both sides of the motor 42. In the above configuration, the guides 0 and 4, the guide 3, the motors 32 and 42, and the timing bed 44 constitute a camera 2 moving mechanism. Guide 40, 40 Guide 30 can use various rear actuators, but in this case, it uses a button.

By rotating the movement mechanisms 2 and 42, the camera 20 can be moved to the desired position in the plane, and the plane from the corner of 200 can be photographed.

The drive system is not limited to the above using a tab, but various rear actuators can be used.

6 That

In addition to the above, an image processing apparatus 5 using the power source 4 shown in 2 is installed.

7 How to use

Taking a solar cell 30 as an example of the cover 20, a method for using 0 of a clear large battery will be described.

The solar cell 3 manufactured and produced by the net equipment is then sent to 0 of the clear positive battery via the envelope. The solar cell that was sent, provided between the pair of guides 4 and 4 on the guide guide side

Move up 5 and reach dark room 0. Acti on the face of the guide It can be turned by projecting a fitting that is provided for insertion and removal.

The solar cell 200, which has reached the specified position, stops at the dark room entrance 2 with the transparent glass 2 facing down, and is removed from the source. Since 2 is smaller than the opening 2 and light enters the room from the surroundings, the upper body of 2 is in the stage described later.

Flow in the direction of 2 from the power source. 20 Takes pictures with camera 2.

When the body of 20 is photographed by 0 and inspected by the image, the camera 2 can be photographed while being fixed in the dark room 0 without providing a moving mechanism. In this case, the difference between the solar cell 28, the solar cell 28 with several solar cells 28 connected with the lead 29, and the trix-like solar cell 3 with the string 25 connected with the serial number 29 But.

When the solar cell 28 arranged in a tox shape on the solar cell 3 is shaded by 0 and inspected by the image, a moving mechanism is provided so that the camera 20 can be moved in the dark room 0. Take a picture.

Due to the movement mechanism 2 2, the camera 20 shadows the positive battery cell 28 arranged in the shape of a trick on the solar cell 3, and the data is transferred to an image processing device such as a shin-son. Send. The physical device extracts and analyzes the portion of the solar cell 28 that does not emit light, analyzes it, determines whether or not each solar cell 28 is not, and determines whether or not it is negative for all the solar cells 28. Judge whether or not he is 30.

The shadow from camera 2 can also be moved by moving the camera for each battery cell, or a few cells, or fixed without moving the camera, so that 3 battery cells can be used.

In the above, the description of the darkroom was explained. However, in the case of the positive battery 30, the back side 22 is opaque and has sufficient properties. In addition, the dark room 0 is also composed of an opening. Therefore, it is unnecessary when 2 is held in close contact with the opening and is larger than the opening 2 and the body of the opening 2 is covered by the cover 200.

However, if 20 is smaller than opening 2 or if it is supported without being placed above opening 2, light enters 0 from the middle, so it is necessary for the stage. . The physical barrier will be described below.

8-stage out

In the state of implementation, as shown in 4 It is well formed. The direction of 0 is provided with 30 of 30 at one end. The cam 302 is supported by two arms 303, and the arm 33 is rotated up and down around the C by two aligners 304.

Between this 400 and the opening 220, there is provided a spoof 402, etc. that has a sexiness, such as a metal, a synthetic resin, etc., which shields the edge from being formed. The spot 402 is provided on the surface that contacts the opening 2. It supports 40 and 200 at its edges and is also a support stage.

The range of 400 is larger than the opening 2, smaller than 200 of the opening, and 30 of 2000.

In the embodiment, a pair of molds 40 3 40 3 is provided on the side of 00 as shown in 5 b), and 400 4 having the edge shape shown in 5 (a) is provided between 40 3 43 of this pair. Enter. The end of the mold 40 8 is provided with a stop 40 4, which is turned 400. Sponge 402 is in close contact with the opening. 200 is placed on the sponge 4 2 of 4 in the opening 2. Open and close the 0 side of the surface, and replace 400 according to the law of 2000.

8 3 steps out 3 The second step of the implementation corresponds to the case where the law of 200 changes in a small lot. In the case of 500, two pairs of shields are automatically moved according to the law of 20 by an actuator.

The process will be described with reference to FIG. In the embodiment, the 5a edge plate is divided into four pairs of 50 5 and 50 2 52 as shown in Fig. 6 a). Place these plates on the side of the device in the same way as shown in Fig. 5. 50 is sexual. 50 2 has a 50 that can be inserted and slided.

Place 50 502 as shown in 6 (b) and move 50 502 closer to the actuator according to the law of 200, and change the size. 200, 50 502. Therefore, in this embodiment, 5052 also serves as a support stage.

As shown in these figures, a pair of 50 50 is connected by two 50 3 50 3. One of the screws 53 is right and the other is left. Rotate the other 503 503 with the piece 504 with the timing 5 5 5 5. Secure the 8 rackets 5 07 and 5 4 4 supporting the screws 50 3 in place. You can move each other up and down by rotating the screen 504. In addition, confirm with the 50 shinda. However, by adopting the same structure for 50 2 50 2, the plate method can be adjusted to the size of 200.

8 4 steps out 4

This is the step of blocking the edge that can be formed between the opening 2200 and the opening. In the embodiment, as shown in FIG. 8, the guide 4 for feeding the positive battery carried into 00 is provided with 600 described below.

Remove the seat 6 on the side of the guide 4 of the pair. 60, a squirrel-shaped sheet that hangs down toward the guide 4 and covers the top of the opening 2 of the inspection 00. This sheet 6 can be edged, and then the direction of 200 can be blocked. The direction of the right angle of the inspection is zero. For this purpose, a carrying shape 602 between the pair of guides 4 is provided. 602 is supported in the dark room and is placed so that it can be exposed to the opening 2 as well. Furthermore, 602 is connected to a book-like portion 603 because there is a separation of the darkroom mouth 2200. This pair of hook-like parts 603 has a sponge-like part 604 having kibble properties. This is done as a book-like part. This

The direction of the inspection 00 in the direction perpendicular to the direction of 200

Implementation of using 9

0 is a diagram showing a state of lightening that can make the dark room small. Inside the room, there are 24 made of Aum, which are provided to the opening. This 240 is finished, and the camera 2 attached to the surface of the dark room is supported by the opening 2 by being inclined with respect to the opening 2.

20 images can be copied. In this case, the oblique angle is approximately 45, but this is not a limitation.

The camera 0 is movable in a straight z-plane, and by moving, the positive battery cell 28 arranged in a tox form on the solar cell 30 can be removed. The A camera moving mechanism 230 that moves the camera 20 in the z x plane is composed of a z guide 23 and a pair of X guides 232 232. It is attached to the camera 20 z guide 23 and can be moved up and down in the z direction.

z Guide 23 and X Guide 232 can be used with various rear activ- ities and tab screws. Also, the camera 20 can move the camera to shoot the solar cell 28, or you can take several pictures, or you can fix it without moving the camera and use three solar cells.

Then, the camera moving mechanism 230 moves the camera 2 within a right angle to the opening 2, but is not limited to a right angle. The dark room can be lowered and the dark room can be made smaller by raising the reflection 240 that is inclined in this way.

For clarity, it is possible to use 5 from the implementation mode alone, or to combine several 5 from the implementation mode to improve the performance.

Since the solar cell is 00 on the side of the dark room, it is not necessary to put 200 in and out of the dark room. Also, the wiring for passing current to the solar cell is absolutely necessary inside the dark room, even outside the dark room 0. Therefore, it is possible to simplify the darkroom. In addition, Myoyo's 00 is used by placing it in the solar cell 30 or the like. At this time, the washing surface of the solar cell in the dark room 0 is faced down. In the normal construction process, such as the net work of the positive battery 30, it is sent with the surface of the solar battery facing down. In addition, the room method can be reduced by providing a reflection in the dark room. This makes it easy to integrate the manufacturing facilities and sllines about the front and rear.
