1. Field of the Invention
The present invention relates to a method for inspecting a solar battery panel, and in particular to an apparatus for inspecting solar battery panels.
2. Description of Prior Art
Since the solar energy is inexhaustible in supply and always available for use, more and more people pay attention to the solar energy. In order to utilize the solar energy, solar battery panels are used to absorb the sunlight and convert it into electricity. Thus, the manufacture of the solar battery panels has become a sunrise industry.
However, in practice, when the conveyor belt 20a transports the solar battery panel 10a to the inspecting region 100a, the solar battery panel 10a will be inevitably positioned with a little error, so that the center of the solar battery panel 10a cannot be aligned with the center of the inspecting region 100a correctly. At this time, these probes cannot press the electrode lines of the solar battery panel 10a correctly. Thus, when the conveyor belt 20a transports the solar battery panel 10a to the inspecting region 100a, both sides of the inspecting region 100a are provided with a set of positioning means 30a. The set of positioning means 30a presses both sides of the solar battery panel 10a to allow the solar battery panel 10a to be positioned into the inspecting region 100a.
However, since the solar battery panel 10a is light, thin and fragile, the edges of the solar battery panel 10a may suffer damage if the set of positioning means 30a push and position the solar battery panel 10a quickly. Further, the solar battery panel 10a may become warped after being baked in an oven. As a result, the probes may not contact the electrode lines on the surface of the solar battery panel 10a correctly.
Therefore, in order to overcome the above problems, the present Inventor proposes a reasonable and novel structure based on his delicate researches and expert experiments.
The present invention is to provide a positioning method and apparatus for inspecting a solar battery panel, whereby the warping of the solar battery panel can be avoided and the electrode lines can be contacted completely.
The present invention is to provide a positioning method and apparatus for inspecting a solar battery panel, wherein the positioning process is executed step by step to reduce the pressure exerted by the positioning devices to the edges of the solar battery panel, thereby reducing the damage of the solar battery panel caused by the contact-type inspection.
The present invention is to provide a positioning method for inspecting a solar battery panel. Two opposite surfaces of the solar battery panel are provided with an electrode line respectively. The method includes steps of: a) providing a transport platen, a set of positioning devices, a first probe row and a second probe row; b) transporting the solar battery panel to an inspecting region by the transport platen; c) moving the set of positioning devices to position the solar battery panel; d) the first probe row pressing one surface of the solar battery panel, thereby positioning the first probe row to the electrode line on the surface of the solar battery panel; e) after the pressing of the first probe row is executed, the second probe row pressing the other surface of the solar battery panel, thereby positioning the second probe row to the electrode line on the other surface of the solar battery panel; and f) electrically connecting the first probe row and the second probe row to inspect the solar battery panel.
The present invention is to provide a positioning apparatus for inspecting a solar battery panel. Two opposite surfaces of the solar battery panel are provided with an electrode line respectively. The inspecting apparatus includes a transport platen for transporting the solar battery panel to an inspecting region; a set of positioning devices movable on both sides of the solar battery panel to position the solar battery panel into the inspecting region; a first probe row provided in the inspecting region for pressing electrode line on one surface of the solar battery panel; and a second probe row provided in the inspecting region for pressing electrode line on the other surface of the solar battery panel.
In comparison with prior art, the present invention has advantageous features as follows. Since the first probe row and the second probe row are activated to press one after another, the warped solar battery panel can be pressed flat, so that the first and second probe rows contact the electrode lines sufficiently, thereby measuring the voltage and current outputted by the electrode lines accurately. Further, the positioning devices position the solar battery panel in the inspecting region step by step. Elastic positioning means of cushioning property is used to reduce the pressure on the edge of the solar battery panel, thereby reducing the damage of the solar battery panel generated during the inspection. Thus, the yield is improved and the practicability of the present invention can be increased.
The characteristics and technical contents of the present invention will be explained with reference to the accompanying drawings. However, the drawings are illustrative only but not used to limit the present invention.

Two opposite surfaces of the solar battery panel 10 are provided with an electrode line 11 respectively. The transport platen 20 may be a conveyor platen, a platen driven by a motor screw or a platen driven by a cylinder. The transport platen 20 transports the solar battery panel 10 to an inspecting region 100. The set of positioning devices 40 can be a positioning device driven by a motor screw or cylinder. The set of positioning devices 40 include a basic positioning means 41 and an elastic positioning means 42, which are provided on the opposite sides of the inspecting region 100 respectively. The elastic positioning means 42 is provided with an elastic element 421. The elastic element 421 may be a spring. The elastic element 421 cushions the elastic positioning means 42, so that the elastic positioning means can elastically press the edge of the solar battery panel 10.
The set of positioning devices 40 are movable on both sides of the solar battery panel 10, thereby positioning the solar battery panel 10 between two borders 101, 102 of the inspecting region 100. The probe row assembly 30 is driven by a motor screw, a motor cam or a cylinder. The probe row assembly 30 comprises a first probe row 31 and a second probe row 32, both of which are provided in the inspecting region 100. The first probe row 32 and the second probe row 32 press electrode lines 11 on both surfaces of the solar battery panel 10 respectively. After the first probe row 31 and the second probe row 32 are electrically connected with each other, the voltage and current outputted by the solar battery panel 10 can be inspected.

During the inspection of the voltage and current of the solar battery panel 10, a solar simulator (not shown) is used to emit simulated sunlight that will be absorbed by the solar battery panel 10. Thus, the solar simulator is provided above the inspecting region 100 to illuminate the solar battery panel 10. After the solar battery panel 10 absorbs the simulated sunlight, the first probe row 31 and the second probe row 32 can be electrically connected with each other, thereby inspecting a voltage and a current outputted by the solar battery panel 10.
