[0039] The feeding platform 2 has columns 5 at both ends to support the movement of the mounting unit 3. The columns 5 and the mounting unit 3 are arranged in a "well" shape, making the overall structure more stable during operation. The mounting unit 3 can alternately move along the columns 5 towards one side of the feeding platform 2. Figure 1 (The middle part is along the y-axis direction), and the picked-up materials are alternately applied to the application positions detected by the position detection unit 6.

[0040] This application adopts a dual-station alternating operation mode. When any of the mounting units 3 picks up the material, the remaining mounting unit 3 will mount the picked-up material to the corresponding mounting position on the carrier board. The mounting units 3 will not interfere with each other, avoiding collisions and ensuring good safety. It can improve the material mounting cycle time and thus improve the material mounting efficiency.

[0041] Combination Figure 2 and Figure 3 The mounting unit 3 can move alternately to one side of the feeding platform 2.
