The invention provides a high-precision alignment follow-up self-adaptive floating suction head. According to the high-precision alignment follow-up self-adaptive floating suction head, the upper end of a fixing block is located in a pressure bearing block, the pressure bearing block and the fixing block move relatively, the two sides of the fixing block are fixedly installed on external equipment, the pressure bearing block is located between the fixing block and the external equipment, a first mounting hole is formed in the middle of an air path block, the periphery of the lower end of the fixing block is located in the first mounting hole, one side of the air path block is provided with an air connector, the upper end of a suction rod is clamped into the fixing block, the lower end of the suction rod penetrates through the first mounting hole and then is fixedly connected to the upper end of the suction head, the lower end of the suction head sequentially penetrates through a base and a cover plate and then is in contact connection with a chip, and two ends of the base are fixedly connected to the lower end of the air path block and the upper end of the cover plate correspondingly. According to the high-precision alignment follow-up self-adaptive floating suction head, in the material suction process, the situation that the chip is impacted by device movement can be prevented, the positioning precision is high, and the device is wide in chip compatibility range, meets the requirement for large-pressure testing and is high in self-adaptive compatibility.
Description
technical field [0001] The invention belongs to the field of IC test equipment, and in particular relates to a high-precision alignment and self-adaptive floating suction head. Background technique [0002] At present, the vigorous packaging and testing market demand puts forward new requirements for the equipment of packaging and testing companies, which can meet the testing needs of micro chips and high-density pins. However, the existing packaging and testing equipment is difficult to meet the testing requirements of tiny chips and high-density pins. The main reason is that the old packaging and testing equipment has poor automatic performance, and generally uses manual or semi-automatic devices, which are difficult to meet the needs of high precision, automation, high pressure, and wide variety. Existing mechanisms use pins, auxiliary rails, etc. to complete. These methods are prone to parts wear, large assembly errors, small degrees of freedom of parts, and certain li...
