Technical Field

The invention relates to a vehicle which can irradiate the light from bottom to top and is positioned above the vehicle, so that an image acquisition module can clearly acquire the image information of the vehicle, and the accurate alignment effect is achieved.

Background

In the conventional implementation of grain absorption, a light source module is disposed adjacent to or below a visual image capturing module; the light source module irradiates a bright light to a crystal grain bearing disc so as to enable crystal grains positioned on the crystal grain bearing disc to generate reflected light, and the visual image acquisition module acquires image information of the reflected light or the crystal grains; the image information is transmitted to a pick-and-place device, so that the pick-and-place device can pick a crystal grain from the crystal grain bearing disc, and then place the crystal grain at another position for the next process.

Although the above-mentioned die picking and placing method is used by various manufacturers, there are still several problems. First, if the pick-and-place module moves above the die to be sucked, the pick-and-place module blocks the view of the visual image capturing module, so that the visual image capturing module cannot effectively capture the image information of the die, which may cause the pick-and-place module to fail to precisely align the position of the die, thereby causing the process defect caused by alignment defect in the subsequent process. Second, the existing light source module projects the bright light from the top to the die located at the bottom, so the image information captured by the visual image capturing module may be blurred, and the pick-and-place module cannot effectively align the position of the die.

In addition to the above-mentioned die, the die further includes a flip chip substrate, an IC substrate, an LED heat dissipation substrate, an LED sapphire substrate, a glass substrate, a ceramic substrate, a copper foil substrate or a Wafer (Wafer), and the aforementioned components are generally referred to as substrates in the industry at present. Therefore, the existing substrate has the possibility of being taken and placed by the module.

As mentioned above, since the position of the pick-and-place module and the light source module provide the bright light, the alignment of the substrate may be affected, and the subsequent process may be inaccurate, so how to improve the alignment accuracy of the substrate becomes a subject of research by various manufacturers.

Therefore, how to solve the above-mentioned deficiencies of the prior art is a problem to be solved by the present invention.
