It is a device that accurately places surface mount components on the pads by moving the placement head. It is divided into manual and fully automatic types.

[0003] When the IGBT high-speed placement machine is working, the DBC needs to be placed on the carrier for mounting. However, the existing technology usually uses a waffle plate for feeding. However, the waffle plate is not suitable for feeding small-sized DBC boards. At the same time, the efficiency of the waffle plate is low when placing materials, and the loading and unloading speeds during the production process are slow, which affects the overall production efficiency.

[0004] Therefore, it is necessary to propose a small DBC board feeding device for IGBT high-speed placement machine to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a small DBC board feeding device for an IGBT high-speed placement machine, which can effectively solve the problems in the background technology.
