Description

TECHNICAL FIELD

[0001] The utility model belongs to photovoltaic glass measurement technical field especially relates to a kind of photovoltaic glass transmission ratio's test tool. BACKGROUND

[0002] Air float table type transmission ratio measuring machine has high flexibility and accuracy when testing photovoltaic glass of various sizes. It can not only measure large-size photovoltaic glass, such as measuring large pieces of tempered glass with a size of up to 700 mm from the center to the edge, but also measure a wide range of wavelengths, typically covering 380-1100 nm, suitable for spectral characteristic analysis of photovoltaic glass.

[0003] However, when testing photovoltaic glass of various sizes with an air float table type transmission ratio measuring machine, it is difficult to determine the position without affecting the test (ensuring that the glass is clean and leaves no marks). When the glass is pushed under the test light source, it is manually moved, the test path is inconsistent, and the data is unstable. It is difficult to ensure that the same piece of glass has consistent light transmission test positions before and after other test items. The number of various size glasses that need to be tested for transmission ratio on the production line is large, and the test position needs to be controlled, resulting in low test efficiency. INVENTION CONTENTS

[0004] To solve the technical problem of inaccurate position when manually moving the glass during measurement in the background art, the purpose of the present utility model is to provide a test tool for photovoltaic glass transmission ratio, which can solve the above problems.

[0005] The technical solution to achieve the purpose of the present utility model is: a test tool for photovoltaic glass transmission ratio, comprising a measuring table and installation supports with scales, respectively, and a sliding rod. The installation supports are fixed on both sides of the measuring table, and the sliding rod is slidingly installed on the installation supports. The sliding rod is on the measuring table and is used to push the photovoltaic glass to slide on the measuring table.

[0006] In this scheme, the installation supports and the sliding rod are used to accurately determine the position of the photovoltaic glass placed on the measuring table. Specifically, the sliding rod is slidingly installed between the installation supports on both sides of the measuring table and slides on the measuring table. That is, the sliding rod slides on the measuring table with the help of the installation supports, and at the same time, it can push the photovoltaic glass on the measuring table to move to the designated position. Since the sliding rod and the installation supports are scaled, the photovoltaic glass can be placed along the sliding rod first, i.e., the X-direction position is determined, and then the sliding rod pushes the photovoltaic glass to move along the installation support direction, i.e., the Y-direction position is adjusted to the designated scale. In this way, the accurate position of the photovoltaic glass on the measuring table is achieved. The device has a simple structure and can accurately determine the position of the glass on the measuring table with the help of the sliding rod and the installation supports, greatly improving the efficiency of the operator when placing the glass during measurement.

[0007] Further, the slide rod has a connecting rod, the mounting bracket has a fixed rod parallel to the measuring table top, one end of the connecting rod has a mounting sleeve, the mounting sleeve is sleeved on the fixed rod, and the fixed rod has a gap in the mounting sleeve, so that the slide rod can slide on the fixed rod by means of the mounting sleeve, and the slide rod pushes the photovoltaic glass along the length direction of the fixed rod to a specified scale position.

[0008] Further, the mounting sleeve has a locking hole, and a locking knob is mounted in the locking hole and used for being screwed against the fixed rod to be fixed. After the slide rod pushes the photovoltaic glass along the fixed rod to the specified position, the locking knob is screwed against the fixed rod, that is, the positions of the slide rod and the fixed rod are relatively fixed, so that the test accuracy of the photovoltaic glass is prevented from being affected by slight change of the position of the slide rod.

[0009] Further, the mounting bracket is provided with two slide rods that are relatively movable, and the two slide rods can relatively push the photovoltaic glass to slide on the measuring table when sliding along the length direction of the fixed rod, so that the problem that it is inconvenient to pull back the photovoltaic glass after the photovoltaic glass is pushed to a position by one slide rod is solved. The distance between the two slide rods can be adjusted according to the position of the light source and the width of the glass to determine the position of the slide rod, and then the two long edges of the glass are inserted into the slot respectively, and the glass is pushed along the parallel direction of the slide rod to move the test transmittance.

[0010] Further, the slide rod is provided with an open slot below, and the height of the open slot is greater than the thickness of the photovoltaic glass, so that the glass is embedded in the open slot and the slide rod is stable when pushing the photovoltaic glass, and the photovoltaic glass itself does not shake.

[0011] Further, the open slot comprises an upper slot part and a lower slot part, and the thickness of the lower slot part is less than the thickness of the upper slot part. Since the lower slot part is attached to the measuring table, the lower slot part should not be too high when the photovoltaic glass is embedded in the open slot, otherwise the photovoltaic glass is not convenient to extend into the open slot.

[0012] Further, the open end of the lower slot part is provided with a circular arc chamfer, so that the photovoltaic glass is convenient to extend into the open slot from the circular arc chamfer.

[0013] By adopting the technical scheme, the photovoltaic glass measuring device has the following beneficial effects:

The slide rod and the mounting bracket are both provided with scales, the position of the glass in the X direction is determined after the glass is placed along the slide rod, then the slide rod pushes the photovoltaic glass to slide along the mounting bracket to determine the distance in the Y direction, so that the position of the photovoltaic glass on the measuring table can be accurately adjusted.

[0015] (2) the slide rod is slid on the fixed rod by the mounting sleeve, and a locking knob is arranged to fix the slide rod;

[0016] (3) an open slot is arranged at the lower end of the slide rod, and the glass is inserted into the open slot and then pushed, so that the glass is prevented from shaking greatly during the sliding process and affecting the measurement accuracy;

[0027] Preferably, two sliding rods 3 are installed on the mounting bracket 2 and can move relative to each other, which can push photovoltaic glass to slide on the measuring table 1 when sliding along the length direction of the fixed rod 5, to prevent the problem that it is not convenient to pull back after one sliding rod 3 pushes photovoltaic glass to move to the position.The distance between the two sliding rods 3 can be adjusted according to the position of light source and the width of glass to determine the position of the sliding rod 3 first, then the two long edges of the glass are inserted into the slot 7 respectively, and the glass is pushed along the direction parallel to the sliding rod to move for testing transmission ratio.

[0029] Preferably, the mounting sleeve 11 has a locking hole, and a locking knob 6 is installed in the locking hole for tightening and abutting on the fixed rod 5 to fix it.After the sliding rod 3 pushes photovoltaic glass to the specified position along the fixed rod 5, the locking knob 6 is tightened and abuts on the fixed rod 5, that is, the position of the sliding rod 3 and the fixed rod 5 is relatively fixed, to prevent the position of the sliding rod 3 from changing slightly to affect the testing accuracy of photovoltaic glass.
