Description

Technical Field

[0001] This invention belongs to the technical field of automation equipment, and specifically relates to an automatic feeding gripper for automated production of tantalum capacitors. Background Technology

[0002] Tantalum capacitors are made using metallic tantalum (Ta) as the anode material. Tantalum (Ta) is widely used in various industrial sectors such as electrical, electronic, mechanical, chemical, aerospace, defense, and others due to its mechanical and physical properties, including a high melting point, excellent flexibility, and corrosion resistance. Because of its ability to form a stable anodic oxide film, tantalum (Ta) is widely used as the positive electrode material for small capacitors, and its annual usage has increased rapidly in recent years with the rapid development of information technology (IT) industries such as electronics and information communication.

[0003] In the existing tantalum capacitor production process, the PCB board of the tantalum capacitor is first placed in a fixture, and then the fixture is placed into a material box for loading. The equipment then transfers the loaded PCB board to subsequent processes for resin encapsulation and other processing steps.

[0004] The current processing technology involves first loading a jig containing a PCB board with tantalum capacitors into a material frame. The jig needs to be transferred during the production process, and it also needs to be removed from the jig containing the PCB board for subsequent processing. The existing technology uses manual insertion and removal of pins to lock and unlock the jig, which is time-consuming and labor-intensive and cannot meet the requirements of automated production.

[0005] Based on the above problems, designing an automatic feeding and gripping transfer device that can meet the requirements of automated production of tantalum capacitors has become an urgent problem to be solved. Summary of the Invention
