The measured efficiency of the test object and the convenience of the detection operation.

However, in order to clearly and fully disclose the present invention, and to illustrate the preferred embodiment, the detailed description of the embodiments will be described as follows:

Referring to FIG. 1 to FIG. 3 together, a diagram of a preferred embodiment of the present invention is disclosed. 1 is a schematic view showing the configuration of the present invention; FIG. 2 is a side view of FIG. 1; and FIG. 3 is a top view of FIG. The above description of the detection device includes a loading platform 11, a first detecting module 112 and a second detecting module 113, wherein:

The stage 11 has a light transmissive area 111, which may be made of a light transmissive material such as epoxy resin, silicone rubber, quartz or glass (as shown in FIG. 3).

The first detecting module 112 includes a moving unit 16 and an image capturing unit 12, wherein the moving unit 16 can relatively move the stage 11, and the image capturing unit 12 is disposed on the moving unit 16 to transmit light. The area 111 is moved by the moving unit 16 to move relative to the light transmitting area 111. In a specific implementation, the mobile unit 16 is disposed under the stage 11 and includes a slide rail 15 and a slide table 14 disposed under the stage 11, and the slide table 14 is disposed on the slide The rail unit 15 further includes a pulley 162 and a belt 161 disposed at an end of the rail 15 and the belt 161 is disposed on the pulley 162. The slide table 14 is connected to the upper side.

The second detecting module 113 includes a swinging unit 17 and a conductive unit 13 . The swinging unit 17 is disposed on the stage 11 and can swing relative to the transparent area 111 . The conductive unit 13 is disposed on the swinging unit 17 . And the driving of the swing unit 17 is relatively close to or away from the light transmitting region 111. In a specific implementation, the swing unit 17 is pivotally connected to a pivot hole 171 formed on the stage 11 .

The first detecting module 112 further includes a light emitting unit 18 (shown in FIG. 5), and the light emitting unit 18 is disposed under the stage 11 corresponding to the light transmitting area 111; the light emitting unit 18 includes a halogen. The light-emitting unit 18 can adjust the number of halogen lamps according to actual needs; the first detecting module 112 further includes a light-shielding component 19 (shown in FIG. 5), and the light-shielding component 19 is disposed on the upper surface of the loading platform 11. Corresponding to the transparent area 111; the image capturing unit 12 includes a lens and a charge coupled component.

In practical applications, the operator can send a first detection through a processing module (such as a microprocessor or a microcontroller) after the object 2 is placed on the transparent area 111 of the stage 11. The command or a second detection command is sent to the detecting device, so that the detecting device requires the first detecting module 112 to perform automatic optical detection to obtain an image data of the object to be tested 2 or request the second detecting module 113 to perform the power of the object to be tested 2 IV test to obtain an electrical data of the test object 2. The processing module can compare and analyze the image data or the electrical data to determine the flaw condition or electrical characteristics of the object 2 to be tested.

After receiving the first detection command, the detecting device commands the first detecting module 112 to perform automatic optical detection of the object to be tested 2 according to the following steps: first, commanding the lower portion of the loading table 11 corresponding to the light transmitting region 111 hair The light unit 18 emits light to the light-transmitting area 111, so that the image capturing unit 12 corresponding to the light-transmitting area 111 under the stage 11 can clearly obtain the image data of the object to be tested 2 through the light-transmitting area 111, and is shielded by light. The component 19 shields the light-transmitting region 111, which can reduce the interference and diffraction of external light to obtain clear image data. Then, the pulley 162 of the moving unit 16 is commanded to rotate, so that the belt 161 disposed on the pulley 162 drives the sliding table 14 Moving on the slide rail 15 causes the image capturing unit 12 to move relative to the light-transmitting area 111. Thus, the image capturing unit 12 can capture image data of each part of the object to be tested 2; for example, the object to be tested 2 can be a solar module, the solar module has a plurality of solar cells, and the image capturing unit 12 can capture image data of each solar cell in the solar module; finally, the processing module compares The difference between the image data of the object 2 and a predetermined image data, analyzing and determining the flaw condition of the object to be tested 2; for example, the solar module in the non-defective solar module and the intact sun The module (the preset image data) can be used to determine whether the solar cell in the solar module is broken after the image data of the two are compared.

Then, after receiving the second detection command, the detecting device commands the second detecting module 113 to perform electrical detection of the object to be tested 2 according to the following steps: First, the command carrier 11 is opposite to the light transmitting region. The swinging unit 17 of the swinging portion 17 swings, so that the conductive unit 13 on the swinging unit 17 is changed from being relatively far away from the light transmitting region 111 to be relatively close to the light transmitting region 111, thereby contacting the object to be tested 2 and forming a loop (as shown in FIGS. 4a to 4b). Finally, the processing module analyzes whether the loop is short-circuited or broken. Or the electric leakage of the electric leakage determines whether the object to be tested 2 is functional or not; for example, whether the solar module generates a short circuit or an open circuit, resulting in malfunction.

Thereby, the object to be tested 2 can perform automatic optical detection and electrical detection in the same detection device, and can detect the object to be tested 2 more efficiently, and reduce the detection device without moving and disassembling the object to be tested 2 The required space for the inspection, thereby improving the efficiency of the test and the convenience of the detection operation.
