The invention provides a cooling device for a wire clamp driving motor of a bonding machine. The cooling device comprises an gas leading device which is fixed on the bonding machine; and the gas leading deice is connected with a gas source through a gas inlet pipe and used for respectively leading cooling gas to two sides of a motor mover of the wire clamp driving motor. A cooling method disclosed by the invention comprises the step of leading the cooling gas to the two sides of the motor mover of the wire clamp driving motor. According to the bonding machine disclosed by the invention, the gas leading device is arranged on the wire clamp fixing arm and used for leading the gas to the two sides of the motor mover of the wire clamp driving motor. The cooling gas is led to the two sides of the motor mover simultaneously, so that the cooling efficiency is largely improved; and due to the increment of the cooling efficiency, the fast response of the wire clamp driving motor for driving a wire clamp is ensured, and the working efficiency of a full-automatic lead bonding machine is improved. According to the bonding machine disclosed by the invention, the cooling device with a high cooling efficiency is arranged in the wire clamp driving motor, so that the working efficiency is largely improved.
Description
technical field [0001] The invention relates to a kind of equipment specially suitable for manufacturing or processing semiconductors, in particular to a cooling device, a cooling method and a bonding machine for a wire clip driving motor on a bonding machine. Background technique [0002] Bonding is a welding process that connects the metallized circuit leads or electrodes on the circuit chip with the metal lead frame or the lead electrode wire of the assembled chip in one-to-one correspondence. As a kind of bonding equipment, the bonding machine guides the metal lead wire (gold wire) to make complex and high-speed movements in three-dimensional space through a ceramic thin tube (hatching knife), forming various wire arcs that meet the needs of different packaging forms. [0003] The bonding machine mainly includes: XY working platform, bonding head, material clamping table, loading and unloading device and other components. During the working process of the bonding machin...
