Description

  The present invention relates to a lens group plate in which condensing lenses are arranged side by side, a battery group plate in which a solar cell unit that performs photoelectric conversion is arranged corresponding to the condensing lens, and a frame in which the lens group plate and the battery group plate are mounted A concentrating solar power generation device, a concentrating solar power generation device manufacturing method for manufacturing such a concentrating solar power generation device, and a concentrating solar power generation device for manufacturing such a concentrating solar power generation device The present invention relates to an apparatus for manufacturing an optical solar power generation device.

  Solar power generation devices (solar power generation units) that convert solar energy into electric power have been put into practical use. In order to achieve lower costs and to obtain higher power, the sunlight collected by the condenser lens is used. A concentrating solar power generation device (concentrating solar power generation unit) of a type that takes out electric power by irradiating a solar cell element smaller than the light receiving area of the condensing lens is being put into practical use.

  The concentrating solar power generation device is configured to condense sunlight with a condensing lens and irradiate the solar cell element. Therefore, the solar cell element applied to the concentrating solar power generation device may have a small light receiving area that can receive sunlight collected by the optical system.

  That is, since the solar cell element applied to the concentrating solar power generation device may be smaller than the light receiving area of the condensing lens, the size of the solar cell element can be reduced. Therefore, it is possible to reduce the usage amount of the solar cell element that is an expensive component in the photovoltaic power generation apparatus, and it is possible to reduce the cost. Due to such advantages, the concentrating solar power generation apparatus is being used for power supply in an area where power can be generated using a large area.

  As a concentrating solar power generation device, a simple configuration in which a solar cell module is attached to a support plate is proposed, so that sufficient strength and rigidity can be obtained without increasing the weight, and heat dissipation can be obtained. (For example, refer to Patent Document 1).

  In addition, high-precision alignment is achieved by arranging condensing lenses in a matrix on the side (top surface) of the long frame and arranging solar cell elements on the bottom of the frame corresponding to the condensing lenses. Has been proposed, and a concentrating solar power generation apparatus with improved productivity and improved power generation efficiency has been proposed (see, for example, Patent Document 2).

  In addition, a concentrating solar power generation apparatus in which a condensing lens is arranged in a matrix on the side (top surface) of a long frame and a solar cell element is arranged on the bottom of the frame so as to correspond to the condensing lens. On the other hand, a method for simplifying and increasing the accuracy of the alignment of the condenser lens with respect to the long frame has been proposed (see, for example, Patent Document 3).

  However, in the inventions disclosed in Patent Document 2 and Patent Document 3, it is assumed that the shape of the long frame is formed with high accuracy, and it is necessary to maintain the rigidity of the frame high. The frame had to be made of a high strength steel plate or the like. Accordingly, there has been a problem that increasing the frame strength increases the weight of the frame, resulting in a complicated, sophisticated, and expensive assembly process.

  In addition, as the weight of the frame increases, the tracking drive mechanism that tracks sunlight to the frame increases in size, increasing the equipment cost and increasing the drive power required for frame control during operation, resulting in a decrease in power generation efficiency. There was a problem.

In addition, since the specifications for the dimensional accuracy and assembly accuracy of the frame have become strict with the increase in size of the device (frame), there has been a risk of positional displacement between the condenser lens and the solar cell element.

A lens group plate 10 in which the optical lenses 11 are arranged side by side, a battery group plate 20 in which a solar cell unit 21 that performs photoelectric conversion is arranged in correspondence with the condenser lens 11, and the lens group plate 10 and the battery group plate 20 are mounted. Frame 30.

  For example, the frame 30 is formed in a groove shape by the side portion 31 and the bottom portion 32. The lens group plate 10 is disposed on the side portion 31 of the frame 30 (the upper end portion of the side portion 31), and the battery group plate 20 is disposed in correspondence with the bottom portion 32. The term “corresponding to the bottom portion 32” means that the case is attached to the bottom end portion of the side portion 31 corresponding to the bottom portion 32 in addition to the case where the bottom portion 32 is attached in contact with the bottom portion 32 (FIG. 1B). is there.

Note that the concentrating solar power generation device 1 is shown as a cross-sectional state in order to facilitate understanding of the positional relationship with respect to the manufacturing device.

  The manufacturing apparatus 50 includes a frame transport unit 51 (FIGS. 2A and 2C) for transporting the concentrating solar power generation device 1. The bottom 32 of the concentrating solar power generation device 1 is placed on the frame transport unit 51 and is smoothly transported in the longitudinal direction DL by a ball bear (not shown) included in the frame transport unit 51. The conveyance can be performed automatically or manually.

  In the present embodiment, the battery group plate 20 is fixed to the frame 30 (bottom portion 32) (first fixing step), and the lens group plate 10 is disposed on the frame 30 (side portion 31). After the first fixing step, the frame 30 is positioned in the horizontal direction. The arrangement and fixation of the lens group plate 10 with respect to the frame 30 (side portion 31) will be further described with reference to FIGS. 5A and 5B and the fifth embodiment.

  The concentrating solar power generation device 1 conveyed by the frame conveying unit 51 is positioned in the horizontal direction (corresponding to the plane direction XY / XY plane direction) by the frame positioning unit 53 (FIGS. 2B and 2C).

  That is, the frame positioning unit 53 includes a frame receiving unit 53w (FIG. 2B) that defines positioning in the short direction DS (Y-axis direction) of the concentrating solar power generation device 1 (frame 30), and a frame pressing unit 53p. (FIG. 2B) and a frame stop 53s (FIG. 2C) that defines positioning in the longitudinal direction DL (X-axis direction).

  First, positioning in the longitudinal direction DL is executed. The positioning of the frame 30 in the longitudinal direction DL is performed by, for example, a frame stop portion 53s configured with an air cylinder. When the frame 30 is transported, the frame stop 53s is retracted to a position lower than the frame transport 51 in the height direction DV. Further, when the frame 30 is positioned in the longitudinal direction DL, the frame stop portion 53 s is projected from the frame transport portion 51.

  That is, the frame stop portion 53s protruding from the frame transport portion 51 contacts the respective end portions of the side portion 31 and the bottom portion 32 of the transported frame 30 to stop the movement of the frame 30 and execute positioning. .

  Next, positioning in the vertical direction (height direction DV: Z-axis direction) is executed by the frame support 52 (FIG. 2A). The frame support portion 52 is formed of, for example, an air cylinder, and supports the bottom portion 32 so as to ensure the level of the frame 30 (bottom portion 32). The frame support portion 52 is disposed so as to correspond to the main girder mounting surface 32m to which the main girder is attached when the frame 30 is attached to the system.

  That is, the frame 30 (the bottom 32 serving as a reference surface in the height direction DV) is positioned in a state where it is attached to an actual light collecting system (power generation system) to which the light concentrating solar power generation device 1 is applied. Therefore, the subsequent processing (positioning and alignment) can be executed in the same state as the actual use state, so that a highly accurate and reliable manufacturing method (manufacturing apparatus 50) can be obtained.

  After the frame 30 is positioned in the longitudinal direction DL and the height direction DV, positioning in the short direction DS is performed. Positioning in the short-side direction DS can be executed by pressing the frame 30 with the frame pressing portion 53p against the frame receiving portion 53w arranged in advance as a reference position. The frame pressing portion 53p can be constituted by an air cylinder, for example, but can also be manually positioned. By pressing with an appropriate pressure, the frame 30 can be prevented from being deformed and positioned with high accuracy.

  Positioning in the longitudinal direction DL, positioning in the height direction DV, and positioning in the short direction DS are executed in this order with respect to the frame 30, so positioning of the frame 30 is easily and highly accurately performed. It becomes possible to do. The positioning in the horizontal direction of the frame 30 is defined by the positioning in the longitudinal direction DL and the positioning in the short direction DS.

  For the frame 30 that has been positioned in the horizontal direction, a planar position shift PSxy (FIG. 3C) between the lens group plate 10 and the battery group plate 20 is detected (planar position shift detection step). In the present embodiment, the battery group plate 20 is fixed in advance in the first fixing step, and the lens group plate 10 is disposed corresponding to the frame 30 (for example, disposed in a movable state such as temporary fixing). Therefore, the positional deviation of the lens group plate 10 with respect to the battery group plate 20 can be detected.

  That is, the manufacturing apparatus 50 is based on the image recognition unit 56 as an image recognition unit that recognizes the images of the lens group plate 10 and the battery group plate 20 in the short direction DS of the frame 30 and the image recognized by the image recognition unit 56. And a planar position deviation detection unit 60h that detects (calculates) a planar position deviation PSxy between the lens group plate 10 and the battery group plate 20. Note that detection (calculation) of the planar direction positional deviation PSxy will be further described with reference to FIGS. 3A to 3C.

  The image recognition unit 56 includes a CCD camera (not shown) and a camera lens (not shown). The image recognition unit 56 is configured to be able to variably adjust the lens focus of the CCD camera by an electric signal transmitted from the control / arithmetic unit 60 via the signal communication line 60b.

  That is, the condensing lens 11 (the condensing lens unit 12 and the non-lens unit 13 is focused) so that the concentric steps formed by the condensing lens unit 12 and the non-lens unit 13 of the condensing lens 11 can be recognized as an image. ) And the solar cell unit 21 (for example, the outer periphery of the solar cell element 23 or the top surface of the optical member 24) so that the solar cell unit 21 can be recognized via the non-lens unit 13. Image recognition).

  The center of the condensing lens 11 is obtained by performing arithmetic processing by the control / calculation unit 60 (planar direction positional deviation detection unit 60h, height direction positional deviation detection unit 60v) on the recognized condensing lens 11 and solar cell unit 21. The coordinates (lens center coordinates CLxy (FIG. 3A)) and the center coordinates (battery center coordinates CSxy (FIG. 3B)) of the solar cell unit 21 are obtained. The detection (calculation) of the lens center coordinates CLxy and the battery center coordinates CSxy will be further described with reference to FIGS. 3A and 3B.

  The CCD camera and camera lens of the image recognition unit 56 include the diameter of the non-lens unit 13 of the condensing lens 11 and the distance between the condensing lens 11 and the solar cell unit 21 (the top surface of the solar cell element 23 and the optical member 24). The size is selected in consideration of the size of the solar cell portion 21 (the outer periphery of the solar cell element 23, the outer periphery of the top surface of the optical member 24), and the like.

  In addition, it is also possible to use a single focus lens and adjust the position of the image recognition unit 56 in the vertical direction (height direction DV) using a linear mechanism without performing the focus adjustment by the electric signal. Is possible. That is, when image recognition is performed on the condenser lens 11, the image recognition unit 56 is moved to a higher position in the vertical direction, and the solar cell unit 21 (the solar cell element 23, the top surface of the optical member 24) is moved. When performing image recognition, it is good also as a structure which moves the image recognition part 56 to the low position (position close to the condensing lens 11) of the orthogonal | vertical direction.

  The image recognizing unit 56 is a set of two units arranged corresponding to the condensing lenses 11 arranged on both ends of the lens group plate 10 on the diagonal line, and the condensing lens 11 (the condensing lens unit 12 and the non-condensing lens unit 12). The image of the lens unit 13) or the image of the solar cell unit 21 (the outer edge of the solar cell element 23 or the outer edge of the top surface of the optical member 24) is recognized.

  That is, the shift in the longitudinal direction DL (coordinate X) and the shift in the short direction DS (coordinate Y) (that is, the plane direction position shift PSxy) are two places arranged at both ends on the diagonal line of the lens group plate 10. It is calculated | required corresponding to the condensing lens 11 of this.

  Therefore, the lens group plate 10 on the diagonal line that can most accurately and efficiently detect the positional deviation PSxy in the planar direction between the lens group plate 10 and the battery group plate 20 when the lens group plate 10 and the battery group plate 20 are superimposed. It is possible to detect and efficiently correct the planar position deviation PSxy between the lens group plate 10 and the battery group plate 20 by efficiently executing the planar direction positional deviation correction. (Positioning step).

  Further, the image recognition unit 56 is supported by a scanning support unit 56s (FIG. 2B), and the scanning support unit 56s is pre-positioned similarly to the frame positioning unit 53 and is disposed on both sides in the short direction DS. It is fixed by. Therefore, the image recognition unit 56 can be positioned easily and with high accuracy.

  Since the image recognizing unit 56 is arranged with high accuracy in advance corresponding to the condensing lens 11, the image recognizing unit 56 recognizes the image of the condensing lens 11 (the condensing lens unit 12 and the non-lens unit 13). If this is not possible, the position of the condensing lens 11 is greatly displaced, and it can be easily eliminated as a process failure.

  In the present embodiment, in addition to the planar direction positional deviation detection step, the height direction positional deviation PSz (FIG. 2D) of the lens group plate 10 with respect to the bottom portion 32 is detected (height direction positional deviation detection step). That is, the manufacturing apparatus 50 measures the distance to the lens group plate 10 in the short direction DS of the frame 30 and the lens group plate 10 with respect to the bottom 32 based on the distance measured by the distance measurement unit 57. There is provided a height direction positional deviation detection unit 60v that detects (calculates) the height direction positional deviation PSz (or the inclination angle θ as the height direction positional deviation).

  That is, the distance measuring unit 57 is scanned in the short direction DS indicated by the arrow FDS by the scanning support unit 57s, and measures the distance from the distance measuring unit 57 to the lens group plate 10. Based on the measurement result of the distance measurement unit 57, the height direction positional deviation detection unit 60v is configured to tilt the angle θ of the lens group plate 10 with respect to the bottom 32 (horizontal plane in the short direction DS) (or the height direction positional deviation PSz). ) Can be detected.

  In this embodiment, since the inclination angle θ of the lens group plate 10 with respect to the bottom 32 (horizontal plane in the short direction DS) is detected, the inclination angle θ (or height direction positional deviation PSz) can be corrected. It becomes possible to realize the concentrating solar power generation device 1 having high photoelectric conversion efficiency by aligning the lens group plate 10 (condensing lens 11) and the battery group plate 20 (solar cell unit 21) with high accuracy. It becomes possible.

  In particular, when a member such as the optical member 24 that acts optically with high precision on the concentrated sunlight is applied as a constituent element of the solar cell unit 21, a large effect can be obtained. When the light collection magnification is small and the influence of the inclination angle θ is small, the process can be simplified by omitting the detection and correction of the height direction positional deviation PSz.

  The distance measuring unit 57 can be constituted by, for example, a laser displacement meter. Although a contact displacement meter can be used instead of the laser displacement meter, there is a risk of scratching the lens group plate 10 (the condensing lens 11) to be measured. Is preferably applied.

  Two distance measuring units 57 are arranged in correspondence with the condensing lenses 11 arranged at both ends of the lens group plate 10 in the longitudinal direction DL, and the surface of the condensing lens 11 corresponding to each distance measuring unit 57 is arranged. In this configuration, the inclination (displacement) of the lens group plate 10 with respect to the bottom 32 is measured by scanning. The scanning of the distance measuring unit 57 in the short direction DS is executed by moving along the scanning support unit 57 s positioned by the mechanism holding unit 55.

  In the present embodiment, only the short-side direction DS where the inclination of the frame 30 may appear greatly is measured. However, in order to perform correction with higher accuracy, it is preferable to measure the height direction positional deviation PSz in the longitudinal direction DL.

  Further, when the measurement result (tilt) by the distance measuring unit 57 exceeds a predetermined value (when the tilt angle θ with respect to the horizontal direction is, for example, 0.5 degrees or more), it can be easily excluded as a process defect. It becomes.

  The manufacturing apparatus 50 according to the present embodiment includes a lens alignment unit 71 serving as an alignment unit that corrects the planar direction positional deviation PSxy between the lens group plate 10 and the battery group plate 20 based on the planar direction positional deviation PSxy. Prepare. The lens alignment unit 71 can be configured as an alignment robot to which an articulated robot is applied.

  In the present embodiment, the battery group plate 20 is fixed, and the lens group plate 10 is arranged in correspondence with the frame 30. Therefore, the arranged lens group plate 10 is moved based on the positional deviation PSxy in the planar direction. The plane direction positional deviation PSxy is corrected. That is, the lens group plate 10 is aligned with the battery group plate 20 fixed in the first fixing process (alignment process).

  The alignment process is executed by the lens alignment unit 71. That is, the lens alignment unit 71 is configured to move the arranged lens group plate 10 and correct the height direction positional deviation PSz and the planar direction positional deviation PSxy.

  As described above, the lens alignment unit 71 controls the position of the lens group plate 10 in three dimensions (X, Y, Z, and X, Y, θ), and the positional deviation of the lens group plate 10 with respect to the battery group plate 20. A function of correcting the (planar direction positional deviation PSxy or the height direction positional deviation PSz) and executing alignment between the lens group plate 10 and the battery group plate 20 is provided.

  Therefore, the lens alignment unit 71 includes, for example, a horizontal control mechanism unit 72, a rotation control mechanism unit 73, a vertical control mechanism unit 74, and a lens group holding mechanism unit 75. The configuration of the lens alignment unit 71 may be any configuration as long as the position of the lens group plate 10 can be adjusted.

  The horizontal control mechanism 72 has a function of controlling the position of the lens group plate 10 in the X-axis direction and the Y-axis direction. The rotation control mechanism 73 has a function of controlling the rotation of the lens group plate 10 in the plane direction XY in addition to the position control in the X-axis direction and the Y-axis direction by the horizontal control mechanism 72. The horizontal control mechanism 72 and the rotation control mechanism 73 can easily and reliably correct the positional deviation PSxy in the planar direction of the lens group plate 10.

  Since the vertical control mechanism 74 has a function of controlling the position of the lens group plate 10 in the Z-axis direction, the height direction position shift PSz of the lens group plate 10 can be reliably eliminated. That is, the lens group plate 10 is moved on the basis of the height direction positional deviation PSz (or the inclination angle θ) in a state where the lens group plate 10 is disposed on the frame 30, and the position of the lens group plate 10 in the height direction is adjusted (height direction). Position adjustment process).

  The lens group holding mechanism unit 75 has a suction pad that sucks the lens group plate 10 by vacuum suction, and holds the lens group plate 10 as an arrangement control target.

  The lens alignment unit 71 can be operated by a control signal transmitted from the control / arithmetic unit 60 via the signal communication line 60b. Further, the horizontal control mechanism 72, the rotation control mechanism 73, the vertical control mechanism 74, and the lens group holding mechanism 75 are provided with torque limits so as to stop in an appropriate load state.

  The lens group plate 10, which has been aligned with the battery group plate 20 after the positional deviation (planar direction positional deviation PSxy or height direction positional deviation PSz) is corrected by the lens alignment unit 71, is aligned with the battery group plate 20. In this state, it is fixed to the frame 30 (second fixing step). That is, the lens group plate 10 whose plane direction positional deviation PSxy is corrected by the alignment process is fixed to the frame 30. Before the second fixing step, the lens group plate 10 moved in the height direction position adjusting step is fixed in advance (third fixing step).

  Fixing can be performed manually or by an automatic screwing machine (not shown). The fixing method and the fixing mechanism will be further described with reference to FIGS. 4 to 5B and FIGS. 9 to 12.

  The control / arithmetic unit 60 (FIG. 2A) includes a lens group measured by the plane direction position deviation detection unit 60 h that detects (calculates) the plane direction position deviation PSxy based on the image recognized by the image recognition unit 56 and the distance measurement unit 57. A height direction positional deviation detection unit 60v that detects (calculates) a height direction positional deviation PSz based on the inclination of the plate 10 is provided.

  Further, the control / arithmetic unit 60 moves the lens group plate 10 on the basis of the detected planar direction positional deviation PSxy and height direction positional deviation PSz, thereby causing positional deviation (planar direction positional deviation PSxy, height direction positional deviation PSz). The lens alignment unit 71 serving as the alignment unit executes position control for correcting and aligning.

  The control / arithmetic unit 60 includes a central processing unit (CPU), a program storage device, and a data storage device (not shown). The control / calculation unit 60 controls the image recognition unit 56, the distance measurement unit 57, and the lens alignment unit 71, and processing steps of computation can be executed by a computer program installed in advance in a program storage device. . Further, the cooperation / control of the image recognition unit 56, the distance measurement unit 57, and the lens alignment unit 71 by the control / arithmetic unit 60 is configured to be executed by applying a PLC (Programmable Logic Controller).

  FIG. 3A is an explanatory diagram schematically showing a state in which a positional deviation is detected by recognizing the image of the condensing lens by the manufacturing apparatus / manufacturing method of the concentrating solar power generation apparatus according to Embodiment 1 of the present invention. is there.

  FIG. 3B is an explanatory diagram schematically showing a state in which the positional deviation is detected by recognizing the image of the solar cell unit in the manufacturing apparatus / manufacturing method of the concentrating solar power generation apparatus according to Embodiment 1 of the present invention. is there.

  FIG. 3C schematically shows a state in which the positional deviation of the lens group plate in the plane direction with respect to the battery group plate is calculated based on the positional deviation of the condenser lens shown in FIG. 3A and the positional deviation of the solar cell unit shown in FIG. 3B. FIG.

  The image recognized by the image recognition unit 56 can be displayed on a monitor 56 d provided as an output unit of the image recognition unit 56. The monitor 56d defines a recognized image origin Mp as a reference position of the image recognition unit 56. When an image is recognized by focusing on the condensing lens 11 (condensing lens portion 12), a flat non-lens portion 13 disposed in the center and a condensing lens portion 12 having a protrusion disposed around the center. The step 12s existing at the boundary is recognized (displayed) as an image. The center of the step 12s (the center of the condensing lens 11) is recognized as being shifted with respect to the recognized image origin Mp, for example, as indicated by the lens displacement SL.

  Accordingly, the recognized image is analyzed (calculated) by the plane direction positional deviation detection unit 60h, thereby detecting (calculating) the center coordinate (lens center coordinate CLxy = (CLx, CLy)) of the step 12s with respect to the recognized image origin Mp. ). The coordinate CLx is a distance (coordinate) from the recognized image origin Mp in the X-axis direction (coordinate X), and the coordinate CLy is a distance (coordinate) from the recognized image origin Mp in the Y-axis direction (coordinate Y). ).

  On the other hand, when the image is recognized by focusing on the solar cell unit 21 via the non-lens unit 13, the outer peripheral end 24s of the top surface of the optical member 24 arranged corresponding to the condenser lens 11 according to the focal position. Alternatively, the outer peripheral end 23s of the solar cell element 23 is recognized. The center of the outer peripheral end 24s of the optical member 24 or the outer peripheral end 23s of the solar cell element 23 (the center of the solar cell unit 21) is shifted from the recognized image origin Mp, for example, as indicated by the battery shift SS. Be recognized.

  Accordingly, the recognized image is analyzed (calculated) by the planar direction displacement detection unit 60h, whereby the optical member 24 (outer peripheral end 24s) or the solar cell element 23 (outer peripheral end 23s) with respect to the recognized image origin Mp. The center coordinates (battery center coordinates CSxy = (CSx, CSy)) can be detected (calculated). The coordinate CSx is the distance (coordinate) from the recognized image origin Mp in the X-axis direction (coordinate X), and the coordinate CSy is the distance (coordinate) from the recognized image origin Mp in the Y-axis direction (coordinate Y). ).

  Since the image recognition for the solar cell unit 21 is performed via the non-lens unit 13 provided in the center of the condenser lens 11, the solar cell unit is not affected by the image distortion caused by the condenser lens unit 12 of the condenser lens 11. 21 can be recognized with high accuracy.

  In the present embodiment, the battery group plate 20 is fixed to the frame 30, and the lens group plate 10 is disposed corresponding to the frame 30. Accordingly, by detecting the displacement of the lens group plate 10 with respect to the battery group plate 20 with the battery group plate 20 as a reference, the positional deviation PSxy = (battery displacement SS between the lens group plate 10 and the battery group plate 20). -Lens deviation SL) can be detected.

  In other words, the positional deviation PSxy in the plane direction is calculated as (battery deviation SS-lens deviation SL) = (CSxy-CLxy) = (CSx-CLx, CSy-CLy), and the positional deviation in the longitudinal direction DL is expressed by the coordinate X = (CSx -CLx), and the positional deviation in the short direction DS is calculated as coordinates Y = (CSy-CLy).

  Therefore, it is possible to correct the positional deviation in the longitudinal direction DL by moving the lens group plate 10 in correspondence with the positional deviation (CSx−CLx) in the longitudinal direction DL (coordinate X). Further, it is possible to correct the positional deviation in the short direction DS by moving the lens group plate 10 in correspondence with the positional deviation (CSy−CLy) in the short direction DS (coordinate Y).

  That is, by detecting a positional deviation PSxy (battery deviation SS-lens deviation SL) between the lens group plate 10 and the battery group plate 20 and applying the lens alignment unit 71, the lens group plate 10 is moved. It becomes possible to correct the positional deviation PSxy in the plane direction (alignment of the lens group plate 10 with respect to the battery group plate 20).

  In the present embodiment, since the battery group plate 20 is fixed and used as a reference, the displacement of the lens group plate 10 with respect to the battery group plate 20 is detected. That is, the plane direction positional deviation PSxy between the lens group plate 10 and the battery group plate 20 is calculated (detected) as (battery deviation SS−lens deviation SL).

  On the other hand, when the lens group plate 10 is fixed and the battery group plate 20 is arranged in correspondence with the frame 30 to detect the positional deviation PSxy of the battery group plate 20 with respect to the lens group plate 10 in the plane direction (Embodiment) 2) is calculated (detected) as a plane direction positional deviation PSxy = (lens deviation SL−battery deviation SS).

  In addition, without detecting the positional deviation of the lens group plate 10 with respect to the battery group plate 20, with the battery group plate 20 fixed and the lens group plate 10 prepared, the respective centers (arrangements) are individually set and calculated. By processing, it is also possible to calculate the positional deviation and move the lens group plate 10 with respect to the battery group plate 20 so as to correspond to the calculated positional deviation. For example, the lens group plate 10 is set in a predetermined location at a location remote from the battery group plate 20 (frame 30) by the lens alignment unit 71, and is remote from the previously determined position of the battery group plate 20. It is also possible to perform alignment by moving from the place.

  FIG. 4 is a cross-sectional view schematically illustrating a state in which the positional deviation of the lens group plate in the height direction is corrected by the manufacturing apparatus / manufacturing method of the concentrating photovoltaic power generation apparatus according to Embodiment 1 of the present invention.

  The lens group plate 10 is attached to the frame 30 (side portion 31) by a lens group plate plane holder 16 and a lens group plate vertical holder 17 as the lens group plate holder 15. At the stage where the positional deviation (plane direction positional deviation PSxy and height direction positional deviation) is corrected and alignment in the plane direction XY / position adjustment in the height direction DV is performed, the lens group plate 10 holds the lens group plate plane. It is fixed to the frame 30 by the tool 16 / lens group plate vertical holder 17.

  Since the lens group plate plane holder 16 and the lens group plate vertical holder 17 are integrated as the lens group plate holder 15, the plane direction position shift PSxy and the height direction position shift PSz are corrected with high accuracy. It becomes possible to do. Details of the lens group plate plane holder 16 will be described with reference to FIGS. 5A and 5B.

  In the present embodiment, the battery group plate 20 is fixed, and the positional deviation of the lens group plate 10 with respect to the battery group plate 20 is corrected to adjust the positional deviation between them and align them. Accordingly, the lens group plate 10 is arranged in correspondence with the frame 30 by the lens group plate holder 15 and the lens group plate vertical holder 17 so that the positional deviation can be detected.

  That is, in the first fixing step, the battery group plate 20 is fixed, and the lens group plate 10 is arranged on the frame 30 by the lens group plate plane holding tool 16 that adjusts and holds the position of the lens group plate 10 in the plane direction XY. Is done. In the first fixing step, the lens group plate 10 is disposed on the frame 30 by the lens group plate height holder 17 that adjusts and holds the position of the lens group plate 10 in the height direction DV with respect to the bottom 32.

  A lens protection resin 16r for preventing the lens group plate 10 from being broken or chipped and protecting the lens group plate 10 is attached to the end of the lens group plate 10. The lens group plate 10 to which the lens protection resin 16r is attached is held by a metal lens group plate holder 15.

  The lens group plate holder 15 includes a lens group plate plane holder 16 that adjusts the position of the lens group plate 10 in the plane direction XY, and a lens group plate vertical holder that adjusts the position of the lens group plate 10 in the height direction. The tool 17 is comprised.

  The lens group plate 10 is inserted by being slid from the longitudinal direction DL into the slide frame portion 16f of the lens group plate plane holder 16 (first fixing step). On the other hand, the lens group plate 10 is disposed such that it does not move by tightening the vertical fixing screw 17b of the lens group plate vertical holder 17 with an appropriate pressure.

  In the arrangement state of the lens group plate 10 described above, the image recognition unit 56 (and the plane direction position shift detection unit 60h) detects the plane direction position shift PSxy (plane direction position shift detection step), and the distance measurement unit 57 ( The height direction position deviation detection unit 60v) detects the height direction position deviation PSz (height direction position deviation detection step).

  Next, the lens alignment unit 71 is applied to correct the plane direction positional deviation PSxy (positioning process), and the height direction positional deviation PSz is corrected (height direction position adjusting process). The alignment step and the height direction position adjustment step can be performed simultaneously by the function of the lens alignment unit 71. In the height direction position adjusting step, the vertical fixing screw 17b is loosened in advance, and the lens group plate 10 is movable in the height direction DV.

  The lens group plate 10 is fixed in a state where the lens group plate 10 is corrected (held by the lens alignment unit 71).

  That is, first, the vertical fixing screw 17b is tightened to fix the lens group plate 10 so as not to move in the height direction DV (third fixing step). That is, the lens group plate 10 is fixed in the height direction DV before the lens group plate 10 is fixed in the plane direction XY (second fixing step). Therefore, the lens group plate 10 is fixed to the frame 30 in a state in which the positional deviation in the height direction DV (height direction positional deviation) is corrected by the lens group plate vertical holder 17.

  Through the third fixing step, the lens group plate 10 is fixed to the frame 30 in a state where the inclination with respect to the bottom portion 32 is corrected. Therefore, the solar cell unit 21 can be faced with high accuracy even with respect to the lens group plate 10 employing the condensing lens 11 having a high condensing magnification, and high photoelectric conversion efficiency can be realized. .

  FIG. 5A is a cross-sectional view schematically showing a state in which the positional deviation in the planar direction of the lens group plate is corrected by the manufacturing apparatus / manufacturing method of the concentrating solar power generation apparatus according to Embodiment 1 of the present invention.

  FIG. 5B is an enlarged cross-sectional view showing an enlarged main part of the cross-section at the arrow BB in FIG. 5A.

  As described above, the lens group plate 10 is arranged on the frame 30 by the lens group plate plane holder 16 (slide frame portion 16f) in the first fixing step. Further, since the lens group plate 10 is slidable with respect to the slide frame portion 16f, the plane direction positional deviation PSxy is corrected in the alignment step.

  The lens group plate 10 is fixed to the frame 30 in the height direction DV (third fixing step) in a state where the positional deviation of the lens group plate 10 is corrected (held by the lens alignment unit 71), and then the slide frame portion 16f. The lens group plate 10 is fixed by the lens group plate plane holder 16 by tightening the plane fixing screw 16b of the lens group (second fixing step).

  That is, after the third fixing step, the lens group plate 10 is clamped between the upper and lower surfaces of the slide frame portion 16f and fixed to the frame 30 by tightening the slide frame portion 16f (plane fixing screw 16b) in the second fixing step. Is done. Since the lens group plate 10 is fixed to the lens group plate plane holder 16 via a lens protection resin 16r having appropriate elasticity, the stability can be improved.

  As described above, after the vertical fixing screw 17b is tightened to fix the lens group plate 10 in the height direction DV corresponding to the lens group plate vertical holder 17, the plane fixing screw 16b is tightened to fix the lens group plate plane holder 16 to the lens group plate vertical holder 16. Since it is fixed in the plane direction XY (longitudinal direction DL and short direction DS), it is possible to correct the positional deviation of the lens group plate 10 easily and with high accuracy.

  In addition, as described above, the concentrating solar power generation device manufacturing method according to the present embodiment has a non-lens portion 13 disposed in the center and a condensing portion that is disposed around the non-lens portion 13 and condenses sunlight. A lens group plate 10 in which a condensing lens 11 having a lens portion 12 is arranged side by side, a battery group plate 20 in which a solar cell portion 21 that performs photoelectric conversion is arranged corresponding to the condensing lens 11, a lens group plate 10 and This is a method for manufacturing a concentrating solar power generation device 1 including a frame 30 on which a battery group plate 20 is mounted.

  That is, in the first fixing step of fixing the battery group plate 20 to the frame 30, the positioning step of positioning the lens group plate 10 with respect to the battery group plate 20 fixed in the first fixing step, and the positioning step A second fixing step of fixing the aligned lens group plate 10 to the frame 30.

  Accordingly, it is possible to correct the positional deviation PSxy in the planar direction between the lens group plate 10 and the battery group plate 20 and to perform positioning, so that the influence of the shape accuracy of the frame 30 is eliminated and the lens group plate 10 and the battery are removed. Positioning with the group plate 20 can be easily and accurately performed with good workability, and the photoelectric conversion efficiency (the ratio of the generated power to the incident light amount) is high. The solar power generation device 1 can be manufactured at low cost.

  Further, in the concentrating solar power generation device manufacturing method according to the present embodiment, after fixing the battery group plate 20 in the first fixing step, the position of the lens group plate 10 in the planar direction XY is adjusted and held. The lens group plate 10 is attached to the frame 30 by the lens group plate plane holder 16 and the lens group plate height holder 17 that adjusts and holds the position of the lens group plate 10 in the height direction DV with respect to the bottom 32 of the frame 30. A height direction position adjusting step of adjusting the position of the lens group plate 10 in the height direction DV with respect to the bottom 32 by the lens group plate height holder 17 in the disposed state, and a height direction DV by the height direction position adjusting step. A third fixing step of fixing the lens group plate 10 adjusted in position by the lens group plate height holder 17, and a third fixing step. Later, in a second fixing step to fix the lens unit plate 10 by lens plate plane retainer 16.

  Therefore, after the lens group plate plane holder 16 and the lens group plate height holder 17 are applied and the lens group plate 10 is arranged on the frame 30, the lens group plate 10 is displaced in the height direction with respect to the bottom 32 of the frame 30. Since the position in the height direction DV is fixed by adjusting PSz, and then the alignment in the plane direction XY is executed and fixed, the position of the lens group plate 10 in the plane direction XY with respect to the battery group plate 20 The alignment and the alignment of the lens group plate 10 in the height direction DV with respect to the battery group plate 20 (the bottom portion 32 of the frame 30) can be easily and accurately performed and fixed.

Based on FIG. 6 and FIG. 7, the concentrating solar power generation device, the concentrating solar power generation device manufacturing method, and the manufacturing device for manufacturing the concentrating solar power generation device according to the present embodiment will be described.

  FIG. 6 is a cross-sectional view showing a schematic cross section in the short-side direction of the concentrating solar power generation device according to Embodiment 2 of the present invention.

  The basic configuration of the concentrating solar power generation device 1 according to the present embodiment is the same as that of the concentrating solar power generation device 1 according to the first embodiment. The matter will be explained.

  In the concentrating solar power generation device 1 according to the present embodiment, the lens group plate 10 is fixed to the frame 30 (side part 31), and the battery group plate 20 is arranged on the frame 30 (bottom part 32) (first). Fixing process). Therefore, the battery group plate 20 is aligned with the lens group plate 10 by detecting the positional deviation of the battery group plate 20 in the planar direction relative to the lens group plate 10 and correcting the positional deviation of the planar direction. With this configuration, since the processing process for the lens group plate 10 with low mechanical strength is simplified, it is possible to reduce the number of process steps and manufacture the concentrating solar power generation device 1 at low cost.

  That is, the lens group plate 10 is fixed to the frame 30 (side portion 31) via the lens group plate holder 15, and the battery group plate 20 is coupled to the frame 30 and the position of the battery group plate 20 in the planar direction XY.

It can be set as the concentrating solar power generation device 1 with high light efficiency.

  Since other configurations are the same as those of the first embodiment, description thereof is omitted.

  FIG. 7 is a side view schematically showing a schematic configuration of the concentrator photovoltaic device manufacturing apparatus according to Embodiment 2 of the present invention as viewed from the side of the concentrator photovoltaic device. Note that the concentrating solar power generation device 1 is shown as a cross-sectional state in order to facilitate understanding of the positional relationship with respect to the manufacturing device.

  As described above, in the concentrating solar power generation device 1 according to the present embodiment, the battery group plate 20 is disposed on the bottom 32, and the positional deviation PSxy in the planar direction of the battery group plate 20 with respect to the lens group plate 10 is detected. It is configured to correct.

  Moreover, since the basic structure of the manufacturing apparatus 50 which concerns on this Embodiment is the same as that of the manufacturing apparatus 50 which concerns on Embodiment 1, a different matter is mainly demonstrated.

  In manufacturing apparatus 50 according to the present embodiment, since it is necessary to correct the positional deviation of battery group plate 20, battery alignment unit 71 s as an alignment unit that corrects the positional deviation of battery group plate 20 is used as battery group plate. 20 is arranged at a position facing 20. That is, the battery alignment unit 71 s is disposed on the opposite side to the lens alignment unit 71 in the first embodiment (below the battery group plate 20 in the height direction DV).

  The configurations of the frame transport unit 51, the frame support unit 52, and the frame positioning unit 53 are the same as those in the first embodiment. The configurations of the image recognition unit 56 and the distance measurement unit 57 are the same as those in the first embodiment, the image recognition and the distance measurement are performed in the same manner as in the first embodiment, and the plane direction positional deviation PSxy is applied to the control / calculation unit 60.

The function of correcting the displacement PSxy) and aligning the battery group plate 20 with respect to the lens group plate 10 is provided. Therefore, the battery alignment unit 71s includes, for example, a horizontal control mechanism unit 72s, a rotation control mechanism unit 73s, a vertical control mechanism unit 74s, and a battery group holding mechanism unit 75s.

The mechanism part 75s functions corresponding to the lens group holding mechanism part 75s. The battery group holding mechanism 75s holds the battery group plate 20.

  Further, as described above, the concentrating solar power generation device manufacturing method according to the present embodiment is arranged around the non-lens portion 13 and the non-lens portion 13 arranged in the center, as in the first embodiment. A lens group plate 10 in which a condensing lens 11 having a condensing lens portion 12 that condenses light is arranged side by side, and a battery group plate 20 in which a solar cell portion 21 that performs photoelectric conversion is arranged corresponding to the condensing lens 11. And the concentrating solar power generation device 1 including the lens group plate 10 and the frame 30 on which the battery group plate 20 is mounted.

  That is, in the first fixing step of fixing the lens group plate 10 to the frame 30, the alignment step of aligning the battery group plate 20 with respect to the lens group plate 10 fixed in the first fixing step, and the alignment step A second fixing step of fixing the aligned battery group plate 20 to the frame 30.

<Embodiment 3>
Based on FIG. 8A thru | or FIG. 8C, the processing flow performed in Embodiment 1 and Embodiment 2 is demonstrated as Embodiment 3. FIG.

  8A to 8C are flowcharts illustrating a processing flow of the concentrating solar power generation device manufacturing method according to Embodiment 3 of the present invention.

  The basic configuration follows the concentrating solar power generation device described in the first embodiment and the second embodiment, the manufacturing device for the concentrating solar power generation device, and the manufacturing method for the concentrating solar power generation device. Explanation will be made with reference to the reference numerals.

Step S1:
A frame 30 is prepared. The frame 30 has a side portion 31 and a bottom portion 32, the lens group plate 10 is disposed on the top portion of the side portion 31, and the battery group plate 20 is disposed on the back surface of the bottom portion 32.

Step S2:
It is determined whether or not the battery group plate 20 is fixed. When the battery group plate 20 is fixed (step S2: YES), the process proceeds to step S3. When the battery group plate 20 is not fixed (step S2: NO), the process proceeds to step S10.

  Note that the determination in this step can be determined in correspondence with, for example, each model. For example, the first model is a product in which the battery group plate 20 is fixed and the lens group plate 10 is disposed, and the second model is a product in which the lens group plate 10 is fixed and the battery group plate 20 is disposed. It is possible to adopt the form.

  In the present application, as described above, the first embodiment is configured to fix the battery group plate 20, and the second embodiment is configured to fix the lens group plate 10.

Step S3:
The battery group plate 20 is fixed to the frame 30 (bottom portion 32) (first fixing step). Further, the lens group plate 10 is disposed on the frame 30 (side portion 31) (first fixing step). As described above, the placement is performed, for example, by lightly tightening the plane fixing screw 16b and the vertical fixing screw 17b to prevent movement due to its own weight. By this step, the lens group plate 10 and the battery group plate 20 are placed on the frame 30.

  The frame 30 on which the lens group plate 10 and the battery group plate 20 are placed is set in the manufacturing apparatus 50. That is, the frame 30 is conveyed via the frame conveying part 51, and positioning is performed by applying the frame positioning part 53 and the frame support part 52 (the frame stop part 53s is applied to the longitudinal direction DL, and the short direction The frame receiving portion 53w and the frame pressing portion 53p are applied to the DS, and the frame supporting portion 52 is applied to the height direction DV to perform positioning processing on each).

Step S4:
A planar direction positional deviation PSxy of the lens group plate 10 with respect to the battery group plate 20 is detected (planar direction positional deviation detection step). Specifically, the plane direction positional deviation PSxy is obtained in correspondence with the condensing lenses 11 arranged at both ends on the diagonal line of the lens group plate 10. Further, the positional deviation PSxy in the planar direction is detected by comparing the lens center coordinates CLxy indicating the center of the condenser lens 11 and the battery center coordinates CSxy indicating the center of the solar cell unit 21 with each other.

  In this step, since the solar cell unit 21 is fixed and the condensing lens 11 is disposed, the positional deviation of the condensing lens 11 with respect to the solar cell unit 21 is detected. The detection of the displacement in the parallel direction is executed by the following processing flow. The following processing flow can be easily and efficiently executed with high accuracy by incorporating it in the control / arithmetic unit 60 in advance as a computer program.

  First, the image recognizing unit 56 is applied to recognize an image formed by the condensing lens 11 (a step appearing at the boundary between the condensing lens unit 12 and the non-lens unit 13). Note that the image recognition unit 56 (CCD camera) is focused on the condenser lens 11. Further, when the distortion of the frame 30 or the like is large and the center of the condenser lens 11 does not exist within the image recognition range of the image recognition unit 56, it can be removed as a process defect.

  The image of the condensing lens 11 recognized by the image recognition unit 56 is subjected to appropriate image processing by the control / arithmetic unit 60 (planar direction position deviation detecting unit 60h), whereby the center coordinates (lens of the condensing lens 11) The center coordinate CLxy) is detected (calculated). The detection result can be temporarily stored in the control / arithmetic unit 60 as appropriate.

  Next, an image (for example, the outer periphery of the solar cell element 23 or the outer periphery of the optical member 24) formed by the solar cell unit 21 arranged on the battery group plate 20 is recognized. Note that the image recognition unit 56 (CCD camera) is focused on the solar cell unit 21. Further, when there is a positional deviation of the solar cell unit 21 with respect to the battery group plate 20 and the center of the solar cell unit 21 does not exist within the image recognition range of the image recognition unit 56, it is obvious that this step is not necessary. It is preferable to eliminate it by a preliminary inspection in advance.

  The center coordinate (battery center coordinate CSxy) of the solar cell unit 21 is detected (calculated) by performing appropriate image processing by the control / arithmetic unit 60 on the image of the solar cell unit 21 recognized by the image recognition unit 56. To do. The detection result can be temporarily stored in the control / arithmetic unit 60 as appropriate.

  The control / arithmetic unit 60 (planar direction positional deviation detecting unit 60h) detects the positional deviation of the lens group plate 10 with respect to the battery group plate 20 by comparing the temporarily stored lens center coordinates CLxy and the battery central coordinates CSxy. That is, the difference (CSxy−CLxy) of the lens center coordinates CLxy with respect to the battery center coordinates CSxy is a positional deviation PSxy = (CSxy−) of the lens group plate 10 (condensing lens 11) with respect to the battery group plate 20 (solar cell portion 21). CLxy) = (CSx−CLx, CSy−CLy) = (coordinate X, coordinate Y).

  The calculated plane direction positional deviation PSxy (CSx−CLx, CSy−CLy) is temporarily stored in the control / arithmetic unit 60. The image processing by the control / arithmetic unit 60 can be executed simultaneously with the image recognition by the image recognition unit 56.

  Further, the control / arithmetic unit 60 (planar position displacement detection unit 60h) is calculated at two locations (two locations corresponding to the two condensing lenses 11 arranged at the diagonal ends of the lens group plate 10). The amount of movement of the lens group plate 10 relative to the battery group plate 20 is calculated based on the plane direction positional deviation PSxy (calculation processing is executed in a direction to eliminate the plane direction positional deviation PSxy at two locations on the diagonal line, and 2 The amount of movement that minimizes the positional deviation PSxy in the planar direction at the location is calculated as the correction amount of the lens group plate 10 with respect to the battery group plate 20). The control / arithmetic unit 60 temporarily stores the calculated movement amount as a plane direction correction amount. Note that an arithmetic expression for executing the arithmetic processing in the direction in which the planar direction positional deviation PSxy is eliminated can be appropriately set.

Step S5:
It is determined whether or not the inclination of the lens group plate 10 with respect to the bottom 32 is to be corrected. When the inclination is to be corrected (step S5: YES), the process proceeds to step S6. When the inclination is not a correction target (step S5: NO), the process proceeds to step S14.

  Note that the determination in this step can be determined in correspondence with, for example, each model. For example, in the third model to which the condensing lens 11 having a high condensing magnification is applied, the inclination of the lens group plate 10 with respect to the battery group plate 20 greatly affects the photoelectric conversion efficiency. Therefore, it is preferable to select the third model having the condensing lens 11 having a high condensing magnification as a target for correcting the inclination of the lens group plate 10.

  On the other hand, in the fourth model to which the condensing lens 11 having a low condensing magnification is applied, the inclination of the lens group plate 10 does not significantly affect the photoelectric conversion efficiency. Therefore, it is possible to leave the lens group plate 10 as a target for correcting the inclination of the lens group plate 10 in consideration of productivity, production cost, and the like.

Step S6:
The height direction position shift of the lens group plate 10 with respect to the bottom 32 is detected (height direction position shift detection step). That is, the distance measuring unit 57 is scanned by the scanning support unit 57s, and the distance from the distance measuring unit 57 to the lens group plate 10 in the short direction DS is measured. By performing an appropriate calculation process by the control / calculation unit 60 (height direction position deviation detection unit 60v) on the distance measurement result, the height direction position deviation of the lens group plate 10 with respect to the bottom part 32 is detected. The detection result can be temporarily stored in the control / arithmetic unit 60 as appropriate.

  Further, the control / arithmetic unit 60 (height direction positional deviation detection unit 60v) calculates the amount of movement of the lens group plate 10 relative to the battery group plate 20 based on the calculated height direction positional deviation (PSz) (height). (Calculation processing is performed in a direction in which the direction position deviation PSz is eliminated, and a movement amount that minimizes the height direction position deviation PSz is calculated as a correction amount of the lens group plate 10 with respect to the battery group plate 20). The control / arithmetic unit 60 temporarily stores the calculated movement amount as the height direction correction amount. It should be noted that an arithmetic expression for executing the arithmetic processing in the direction to eliminate the height direction positional deviation PSz can be set as appropriate.

Step S7:
In the state where the lens group plate 10 is held by the lens alignment unit 71 in the planar direction positional deviation detection step and the height direction positional deviation detection step with respect to the arranged lens group plate 10, the arrangement is canceled and the movable state is set. . Under the movable state, the lens group plate 10 is moved by the lens alignment unit 71 to correct the plane direction positional deviation PSxy and the height direction positional deviation PSz.

  That is, the position is calculated based on the movement amount of the lens group plate 10 with respect to the battery group plate 20 temporarily stored in the control / arithmetic unit 60 (the correction amount in the planar direction of the lens group plate 10 with respect to the battery group plate 20) calculated in step S4. Displacement is corrected (positioning process). In other words, the arranged lens group plate 10 is moved based on the plane direction positional deviation PSxy to correct the plane direction positional deviation PSxy, and the lens group plate 10 is aligned with the battery group plate 20.

  Further, based on the amount of movement of the lens group plate 10 relative to the battery group plate 20 calculated in step S6 and temporarily stored in the control / arithmetic unit 60 (the height direction correction amount of the lens group plate 10 relative to the battery group plate 20). The positional deviation is adjusted (height direction position adjusting step). That is, the arranged lens group plate 10 is moved based on the height direction positional deviation to correct the height direction positional deviation.

  The alignment process and the height direction position adjustment process are separate processes for convenience of explanation, but can be performed simultaneously as the operation of the lens alignment unit 71.

  Further, when the positional deviation cannot be corrected in the alignment step or the height direction position adjustment step, it can be easily eliminated as a process defect.

Step S8:
The lens group plate 10 that has been moved by correcting the height direction positional deviation (height direction position adjusting process) and correcting the height direction positional deviation is attached to the frame 30 (lens) by the lens group plate height holder 17 (vertical fixing screw 17b). It fixes to the group plate holder 15 / lens group plate plane holder 16) (third fixing step).

Step S9:
The lens group plate 10 that has been moved by the correction (positioning step) of the positional deviation PSxy in the plane direction is fixed to the frame 30 (side portion 31) by the lens group plate plane holder 16 (plane fixing screw 16b) (second fixing step). ). Fixing can be performed manually or by applying an automatic screwing machine (not shown).

Step S10:
The lens group plate 10 is fixed to the frame 30 (side portion 31) (first fixing step). Further, the battery group plate 20 is disposed on the frame 30 (bottom portion 32) (first fixing step). As described above, the arrangement is performed, for example, by lightly tightening the plane fixing screw 25b to prevent movement. By this step, the lens group plate 10 and the battery group plate 20 are placed on the frame 30.

  The frame 30 on which the lens group plate 10 and the battery group plate 20 are placed is set in the manufacturing apparatus 50. That is, the frame 30 is conveyed via the frame conveying part 51, and positioning is performed by applying the frame positioning part 53 and the frame support part 52 (the frame stop part 53s is applied to the longitudinal direction DL, and the short direction The frame receiving portion 53w and the frame pressing portion 53p are applied to the DS, and the frame supporting portion 52 is applied to the height direction DV to perform positioning processing on each).

Step S11:
A planar direction positional deviation PSxy of the battery group plate 20 with respect to the lens group plate 10 is detected (planar direction positional deviation detection step). Specifically, the plane direction positional deviation PSxy is obtained in correspondence with the condensing lenses 11 arranged at both ends on the diagonal line of the lens group plate 10. Further, the positional deviation PSxy in the planar direction is detected by comparing the lens center coordinates CLxy indicating the center of the condenser lens 11 and the battery center coordinates CSxy indicating the center of the solar cell unit 21 with each other.

  In this step, since the condensing lens 11 is fixed and the solar cell unit 21 is disposed, the positional deviation of the solar cell unit 21 with respect to the condensing lens 11 is detected. The detection of the displacement in the parallel direction can be the same as the processing flow described in step S4, and thus detailed description thereof is omitted.

  The control / arithmetic unit 60 (planar direction positional deviation detecting unit 60h) detects the positional deviation of the lens group plate 10 with respect to the battery group plate 20 by comparing the temporarily stored lens center coordinates CLxy and the battery central coordinates CSxy. That is, the difference (CLxy−CSxy) of the battery center coordinate CSxy with respect to the lens center coordinate CLxy is a positional deviation PSxy (CLx−CSx) of the battery group plate 20 (solar cell portion 21) with respect to the lens group plate 10 (condensing lens 11). , CLy−CSy).

  The calculated plane direction positional deviation PSxy (CLx−CSx, CLy−CSy) is temporarily stored in the control / arithmetic unit 60. The image processing by the control / arithmetic unit 60 can be executed simultaneously with the image recognition by the image recognition unit 56.

  Further, the control / arithmetic unit 60 (planar position displacement detection unit 60h) is calculated at two locations (two locations corresponding to the two condensing lenses 11 arranged at the diagonal ends of the lens group plate 10). The amount of movement of the battery group plate 20 with respect to the lens group plate 10 is calculated based on the plane direction positional deviation PSxy (calculation processing is executed in a direction to eliminate the plane direction positional deviation PSxy at two locations on the diagonal line, and 2 The amount of movement that minimizes the positional deviation PSxy in the planar direction at the location is calculated as the correction amount of the battery group plate 20 with respect to the lens group plate 10). The control / arithmetic unit 60 temporarily stores the calculated movement amount as a plane direction correction amount.

  Since the other basic processing flow is the same as that in step S4, detailed description thereof is omitted.

Step S12:
The state of the battery group plate 20 in the planar direction positional deviation detection process with respect to the arranged battery group plate 20 is held by the battery alignment unit 71s, and the arrangement state is canceled to make it movable. Under the movable state, the battery group plate 20 is moved by the battery alignment unit 71s to correct the positional deviation PSxy in the planar direction.

  That is, the position is calculated based on the amount of movement of the battery group plate 20 relative to the lens group plate 10 temporarily stored in the control / arithmetic unit 60 (the amount of correction in the plane direction of the battery group plate 20 relative to the lens group plate 10) calculated in step S11. Displacement is corrected (positioning process). That is, the arranged battery group plate 20 is moved based on the planar direction positional deviation PSxy to correct the planar direction positional deviation PSxy, and the battery group plate 20 is aligned with the lens group plate 10.

Step S13:
The battery group plate 20 that has been moved by the correction (positioning process) of the positional deviation PSxy in the plane direction is fixed to the frame 30 (bottom part 32) by the battery group plate plane holder 25 (plane fixing screw 25b) (second fixing process). .

Step S14:
The lens group plate 10 is moved to correct the planar direction displacement PSxy (positioning step). This step is a case where the inclination of the lens group plate 10 is not a correction target. Since the processing is the same as that in step S7 except that the inclination of the lens group plate 10 is not subject to correction, detailed description thereof is omitted.

Step S15:
The lens group plate 10 that has been moved by the correction (positioning step) of the positional deviation PSxy in the plane direction is fixed to the frame 30 (side portion 31) by the lens group plate plane holder 16 (plane fixing screw 16b) (second fixing step). ). That is, the same processing as in step S9 is performed.

  The fixing process is performed in step S9, step S13, or step S15, and the process is terminated. That is, when the fixing process is finished, the process proceeds to the process for the lens group plate 10 (battery group plate 20) arranged next.

  As described in the first to third embodiments, the concentrating solar power generation device 1 according to the present invention is arranged around the non-lens part 13 and the non-lens part 13 arranged in the center and emits sunlight. A lens group plate 10 in which a condensing lens 11 having a condensing lens portion 12 for condensing is arranged side by side, a battery group plate 20 in which a solar cell portion 21 for performing photoelectric conversion is arranged corresponding to the condensing lens 11, And a frame 30 on which the lens group plate 10 and the battery group plate 20 are mounted.

  The manufacturing method for manufacturing the concentrating solar power generation device 1 according to the present invention includes a first fixing step of fixing either the lens group plate 10 or the battery group plate 20 to the frame 30 and fixing in the first fixing step. An alignment step of aligning the other with respect to either the lens group plate 10 or the battery group plate 20, and the lens group plate 10 or the battery group plate 20 aligned in the alignment step is fixed to the frame 30. A second fixing step.

  Accordingly, it is possible to correct the positional deviation PSxy in the planar direction between the lens group plate 10 and the battery group plate 20 and to perform positioning, so that the influence of the shape accuracy of the frame 30 is eliminated and the lens group plate 10 and the battery are removed. Positioning with the group plate 20 can be easily and accurately performed with good workability, and the photoelectric conversion efficiency (the ratio of the generated power to the incident light amount) is high. The solar power generation device 1 can be manufactured at low cost.

  Since the influence of the shape accuracy of the frame 30 can be eliminated, the strength of the frame 30 can be suppressed and the structure can be simplified. Therefore, the weight and simplification of the frame 30 can be achieved, and the production cost and the operating cost are reduced. It can be set as the concentrating solar power generation device 1 which can be performed.

  Further, in the method for manufacturing the concentrating solar power generation device 1 according to the present invention, the plane direction positional deviation PSxy is obtained as the coordinate X in the longitudinal direction DL of the frame 30 and the coordinate Y in the lateral direction DS.

As a result, the alignment between the lens group plate 10 and the battery group plate 20 can be performed easily and with high accuracy.

  Moreover, in the manufacturing method of the concentrating solar power generation device 1 according to the present invention, the plane direction positional deviation PSxy is obtained in correspondence with the condensing lenses 11 arranged at both ends on the diagonal line of the lens group plate 10. Accordingly, since the planar position misalignment PSxy between the lens group plate 10 and the battery group plate 20 is detected at two positions on the diagonal line where the planar position misalignment PSxy can be detected most accurately and efficiently, two positions are detected. Therefore, it is possible to calculate the amount of movement that minimizes the plane direction positional deviation PSxy and to efficiently correct the positional deviation in the plane direction, and to efficiently execute the positional deviation correction in the plane direction (alignment process).

  Moreover, in the manufacturing method of the concentrating solar power generation device 1 according to the present invention, the plane direction positional deviation PSxy is the lens center coordinate CLxy indicating the center of the condensing lens 11 and the battery center coordinate indicating the center of the solar cell unit 21.

Therefore, since the position of the condensing lens 11 and the position of the solar cell unit 21 can be detected with high accuracy, the positional deviation PSxy in the planar direction between the lens group plate 10 and the battery group plate 20 can be easily and easily performed. It can be detected with high accuracy.

  Moreover, in the manufacturing method of the concentrating solar power generation device 1 which concerns on this invention, lens center coordinate CLxy is set to the image recognized by the image recognition means (image recognition part 56) focused on the condensing lens part 12. FIG. The battery center coordinate CSxy is detected based on the image recognized by the image recognition means (image recognition unit 56) focused on the solar cell unit 21 via the non-lens unit 13. Therefore, since the lens center coordinates CLxy and the battery center coordinates CSxy are detected in a state where the focal positions are aligned with respect to the condensing lens unit 12 and the solar cell unit 21, respectively, the planar position deviation PSxy is detected with high accuracy. Can do.

  Moreover, in the manufacturing method of the concentrating solar power generation device 1 which concerns on this invention, a battery group plate 20 is fixed at a 1st fixing process, and the position in the plane direction XY of the lens group plate 10 is adjusted and hold | maintained. The lens group plate 10 is arranged on the frame 30 by the lens group plate plane holder 16, and the lens group plate 10 is fixed by the lens group plate plane holder 16 in the second fixing step.

  Therefore, since the lens group plate plane holder 16 is applied and the lens group plate 10 is arranged on the frame 30 and then the plane direction positional deviation PSxy is corrected and fixed, the plane direction of the lens group plate 10 with respect to the battery group plate 20 is fixed. The positional deviation PSxy can be easily corrected with high accuracy (the lens group plate 10 is aligned with the battery group plate 20) and fixed.

  Moreover, in the manufacturing method of the concentrating solar power generation device 1 which concerns on this invention, after fixing the battery group plate 20 at a 1st fixing process, the position in the planar direction XY of the lens group plate 10 is adjusted and hold | maintained. The lens group plate 10 is disposed on the frame 30 by the lens group plate plane holder 16 and the lens group plate height holder 17 that adjusts and holds the position of the lens group plate 10 in the height direction DV with respect to the bottom 32. In the height direction position adjusting step of adjusting the position of the lens group plate 10 in the height direction DV with respect to the bottom portion 32 by the lens group plate height holder 17 and the position in the height direction by the height direction position adjusting step. A third fixing step of fixing the adjusted lens group plate 10 by the lens group plate height holder 17, and after the third fixing step, the second fixing In extent, to fix the lens unit plate 10 by lens plate plane retainer 16.

  Therefore, after the lens group plate plane holder 16 and the lens group plate height holder 17 are applied and the lens group plate 10 is arranged, the bottom portion 32 of the lens group plate 10 in the height direction DV of the frame 30 (the frame 30). ) Is adjusted to fix the position in the height direction DV, and then is fixed by executing alignment in the plane direction XY, so that the lens group plate 10 with respect to the battery group plate 20 is fixed. The alignment in the plane direction XY and the alignment in the height direction DV of the lens group plate 10 with respect to the battery group plate 20 (the bottom 32 of the frame 30) can be easily and accurately corrected and fixed. It becomes.
