The device also has good working efficiency and working stability, and the entire device occupies a small area and is easy to transport.

[0083] Example 4

[0084] The above-mentioned LED chip sorting equipment includes a base 1, a support mechanism 2 arranged on the base 1, a material storage device 3, a raw material carrying device 4 and a finished product carrying device 5. The support mechanism 2 is provided with a moving device 6, and the moving device 6 includes a longitudinal moving mechanism 61, a transverse moving mechanism 62 connected to the longitudinal moving mechanism 61 and a vertical moving mechanism 64 connected to the lower end of the transverse moving mechanism 62.

The material plate clamping mechanism 7 can clamp two groups of material plates stably and reliably respectively, thereby improving the installation efficiency while ensuring the work. The storage device in the present invention is different from the existing vertical storage box. The storage device is a flat-laying style, which reduces the height of the entire equipment while ensuring the storage capacity, improves the convenience when discharging materials, and avoids the use of the material box support and the material box moving track on the vertical storage box, thereby relatively reducing the use of the entire equipment's electric energy. After designing a new type of material plate clamping mechanism 7, a receiving tray assembly that cooperates with the material plate clamping mechanism is designed on the raw material carrying device 4 and the finished product carrying device, and the receiving tray assembly can rotate and receive materials in the vertical and horizontal directions. After the raw material carrying device 4 and the finished product carrying device are adjusted in position, the LED chips are sorted by auxiliary structures such as the chip sorting swing arm device 9 and the sorting camera. The sorting machine of the present invention optimizes the process of loading and unloading materials, improves the overall sorting efficiency, is more stable as a whole, occupies less space, has lower manufacturing costs, and is safe and reliable.
