Description

Technical Field

[0001] This utility model relates to the field of photovoltaic glass environment chamber testing technology, and in particular to a photovoltaic glass environment chamber testing fixture. Background Technology

[0002] Photovoltaic glass environmental chamber testing fixtures are supporting equipment for testing photovoltaic glass. During the introduction of photovoltaic glass, relevant aging simulation tests need to be carried out on the photovoltaic glass, mainly including DH (high temperature and high humidity), TC (thermal and cold cycling), and HF (wet freezing), to simulate the impact of harsh outdoor environments on glass materials. This type of test is very common in the reliability assessment of photovoltaic materials. With the continuous development of technology, people have increasingly higher requirements for the manufacturing process of photovoltaic glass environmental chamber testing fixtures.

[0003] Existing photovoltaic glass environmental chambers have certain drawbacks in use. These chambers are designed for aging photovoltaic modules. Inside the chamber, there are rows of roller tracks at the bottom, and corresponding clips on the innermost wall for temporarily and partially fixing the photovoltaic modules vertically (the photovoltaic modules enter the clips along the bottom tracks to complete the placement). The clip fixing area is generally about 60mm wide, and the modules are quite loose inside. However, since the environmental chamber is for static testing, the modules will not move inside, so complete fixation is not necessary.

[0004] Current glass introduction testing involves glass with thicknesses typically ranging from 1.6mm, 1.8mm, 2.0mm, 2.5mm, and 3.2mm, with lengths generally exceeding 1.7m (and areas exceeding 2m²). The glass is introduced into the environmental chamber without any fixtures or jigs, acting as a frame assembly. The following risks or issues have been identified: The glass has no protection on the sides and is prone to breakage on the roller track; The environmental chamber only has a clip on the innermost side, and there is only one clip. The clip is directly fixed to the glass in a bent state. The glass is subjected to asymmetrical force and is in a state of torsional stress, which makes it easy to break and affects the test. During the handling of glass before and after the experiment, the glass is prone to slipping and damage due to the low friction. In particular, the presence of water vapor or surface substances on the glass after the experiment may affect the handling of the glass. To address this, we propose a photovoltaic glass environmental chamber testing fixture. Utility Model Content

It features a three-way roller slide rail design on the side of the fixture, a rubber buffer structure design at the bottom of the fixture, and an overall sliding design for the fixture, which facilitates the sliding installation of glass, provides excellent buffer protection, and facilitates better testing.

[0030] Side slide rail: it is mainly composed of four components: a slide rail, a vertical roller, an upper roller and a lower roller; the cross-section of the slide rail is in a "C" shape, with the characteristic of being narrow at the top and wide at the bottom. The upper and lower planes each vertically extend a small section of vertical surface upward and downward respectively, for fixing the plane rollers; a plane roller is arranged inside the narrow area at the top, and the contact surface / outer cylindrical surface of the roller is 2-5mm lower than the downward extending end of the cantilever beam of the slide rail; a plane roller is fixed on the wide plane area at the bottom, the length of this roller is more than 10mm longer than that of the upper roller, and the cylindrical surface of the roller is 2-5mm higher than the upward extending end of the lower plane; a vertical roller is arranged on the inner vertical surface of the C-shaped slide rail; The three rollers are designed and arranged on the rail in the following order: the upper and lower rollers are on the same vertical plane, which is a single vertical plane, and are installed and fixed on the rail in an equal proportional distance arrangement. It is recommended that the distance is greater than the maximum diameter of the vertical roller. The vertical roller is arranged between the front and rear of the upper and lower rollers, so as to ensure that all three rollers can roll without contacting each other.

[0031] The bottom support guide rail comprises two structures: the exterior is a C-shaped profile, and the interior is a soft rubber material. The outer buffer surface of the rubber fits against the inner wall of the C-shaped rail, and a semicircular arc cavity structure is arranged in the middle of the rubber buffer, which can buffer the impact force from the side of the glass.

[0034] Sliding in of the glass is implemented according to the following steps: 1. Place the glass tooling horizontally on a table top or another operation platform; 2. Place the glass horizontally, insert the end of the short side of the glass into the rollers in the side slide rail, at this time the end support and the two long-side rails support the glass end at the same time; 3. Slowly push the glass to move inward until it contacts the rubber buffer at the bottom; 4. Finally, the tooling with glass can be vertically placed (in the form of an assembly) into an environmental chamber, at this time the rubber strip cavity at the bottom of the deforms under the compression of the glass bottom, and then the side rollers restrict the glass from escaping.
