- the darkroom 110 is hermetically sealed, so if you take a number of shots after the laminating process has been completed and heated, the heat is transferred into the darkroom 110 and the temperature rises. To rise. Due to this temperature rise, the large reflector 140 is thermally expanded. In this state, if the reflector is fixed with ordinary bolts, it will be distorted. Due to the distortion of the reflector, the reflector is warped. In addition, since the reflecting plate 140 is facing upward, there is a possibility that dust and dirt adhere to it and become dirty, and the reflecting surface may be fogged.

- the temperature and humidity controller with filter 1 5 2 removes the dust in the air from 1 5 0 and supplies it to dark room 1 1 0, and filter 1 5 3 removes the dust from the air in dark room 1 1 0.
- the air in the darkroom 110 is cleaned to prevent dust from adhering to the reflector 140 and the camera 120.
- filters 1 5 2 and 1 5 3 may be installed and a dust collector installed at the temperature and humidity controller 1 5 0.
- FIG. 6 is a view showing a state in which an automatic cleaning device 160 for removing dust on the reflecting surface of the reflecting plate 140 is attached, where (a) is a front view and (b) is a side view.
- a support frame 1 6 1 is fixed on both sides of the reflector 1 4 0, and a scraper 1 6 2 is installed between the left and right support frames 1 6 1.
- the scraper 16 2 is moved up and down on the support frame 16 1 1 and intermittently on the reflector 1 4 0 by an appropriate moving means such as a linear actuator (not shown) provided on the support frame 1 6 1 and the like. Can be cleaned and dusted.
- condensation may occur on the reflector plate 140 when it is cold, but condensation can also be removed by wiping with the scraper 16 2.
- the scraper 1 6 2 is preferably one that does not damage the surface of the aluminum reflector 1 4 0.
- a resin plate, a thin bristle brush, or a sponge attached to the tip for condensate removal can be considered.
- FIG. 7A and 7B are diagrams showing the mounting structure of the reflector 140, where FIG. 7A is a front view and FIG. 7B is a cross-sectional view taken along line AA of FIG.
- the reflector plate 140 is supported at the four corners by four support tools 170 supported by the wall surface of the dark room 110.
- the size of the reflecting plate 140 is as large as the size of the object to be measured 200, so that it thermally expands even with a slight temperature change.
- the support 1700 is formed so that the groove 1700a is long in the length direction of the reflector plate 1400 (the left-right direction in FIG.
- the reflecting plate 140 expands or contracts, the expansion and contraction in the length direction can be absorbed by the groove 170 a.
- absorption of expansion and contraction in the width direction is absorbed by the support tool 170 being attached to the dark room 110 in a slidable state.
- the depth of the groove 17 0 a of the upper support 1 70 may be increased to absorb the expansion and contraction in the width direction of the reflector 1 4 0.
- FIG. 8 is a view showing another embodiment in which the temperature of the reflector 140 is kept constant, (a) is a front view, and (b) is a side view.
- a meandering electric heater for temperature adjustment 1 80 is attached to the back surface of the reflector 1 4 0, and a constant current is passed through the electric heater 1 8 0 for temperature adjustment to generate heat. It is what I did.
- the temperature of the reflector 1 40 is due to the heat generated by the electric heater. It is kept constant and can prevent deformation and warpage due to thermal expansion.
- the electric heater for temperature adjustment 180 is divided as appropriate in the longitudinal direction of the reflector 140, and is attached as a plurality of meandering electric heaters.
- the entire 1 40 can be kept at the same temperature.
- the electric heater 180 for temperature adjustment is attached to the entire surface of the reflector plate 140 as in the illustrated embodiment, but it may be provided only at both ends of the reflector plate 140.
- the electric heater for temperature adjustment in FIG. 8 may be a heating / cooling device such as a Peltier element, or a pipe may be configured to flow a fluid such as gas or water for temperature adjustment.
- the solar cell as the object to be measured 200 need only be placed outside the dark room, so that the object 200 to be taken in and out of the dark room is used. A door is not required.
- the power supply and wiring for supplying current to the solar cell may be outside the dark room 110, and is not required at all in the dark room. Therefore, the structure of the darkroom 110 can be simplified.
- the reflecting plate 140 is attached to the object to be measured 200 at an angle, the height of the dark room 110 can be reduced, and the apparatus can be downsized. In addition, incidental work such as digging down the part where the equipment is installed is not necessary to unify the pass lines of the production line.
- the solar cell inspection apparatus 100 of the present invention is used by being placed on a production line such as a solar cell panel. At this time, the solar cell light receiving surface is placed below the upper surface 11 1 1 of the dark room 110. It is placed on the side. In normal processing processes such as laminating solar cell panels, the solar cell's light-receiving surface is transported, so there is no need to reverse when placing it on the inspection device 100, simplifying the manufacturing process Can be
- Temperature / humidity adjuster 1 5 0 can be used to maintain a constant temperature in the compartment 1 1 0 or to provide an electric heater 1 8 0 for temperature adjustment. Warpage can be prevented.
- filters 1 5 2 and 1 5 3 and an automatic cleaning device 1 60 it is possible to prevent the reflecting surface of the reflector 1 4 0 from becoming dirty, and the object to be measured 2 0 0 is clearly displayed. be able to.
