[0002] In the digital tube packaging production process, the working process of the die bonder packaging equipment is generally as follows: the dispensing mechanism dispenses glue at the pad position of the bracket, the ejector pin lifts up the chips, resistors and other materials attached to the wafer ring, and then the swing arm removes the materials from the wafer ring and transfers them to the mounting position where glue has been dispensed to complete the mounting.

[0003] As product functions become richer, the types of devices and chips that need to be mounted on the bracket of the packaging equipment also increase, and multiple devices and chips of different colors are required to be mounted on the same bracket at one time. Therefore, a device that can store multiple chip rings at the same time is needed, and the position of each chip ring can be freely changed for the ejector pin to lift it. The existing chip ring loading device usually uses a rotating structure to place multiple crystal rings at 90 degrees or 120 degrees. When mounting, the required chip ring is transferred to the chip suction position through a rotating mechanism. The overall crystal ring structure is large in size and heavy in load, and has low efficiency. It takes up a lot of space, resulting in a large overall appearance of the packaging equipment and low site space utilization. Therefore, a highly integrated multi-crystal ring loading device is needed to solve the above technical problems. Utility Model Content
