Abstract

The invention provides a zoom lens. The zoom lens comprises a voice coil motor stator, a voice coil motor rotor and an elastic support structure, the voice coil motor rotor is arranged in the voice coil motor stator, a light through hole is formed in the voice coil motor rotor, a zoom lens body is arranged in the light through hole, and the elastic supporting structure is connected with the voicecoil motor stator and the voice coil motor rotor at the same time. When the voice coil motor rotor is electrified in the magnetic field of the voice coil motor stator, the voice coil motor rotor can drive the zoom lens body to reciprocate; according to the zoom lens, the axial movement of the zoom lens body is controlled through electromagnetic induction generated between the voice coil motor stator and the voice coil motor rotor, and the elastic supporting structure is connected with the voice coil motor stator and the voice coil motor rotor at the same time, so that the overall structure issimplified, and the size and the weight are reduced; and the resetting of the voice coil motor rotor and the zoom lens body can be accelerated, the zoom speed is improved, and the zoom stability is maintained.

Description

technical field [0001] The application belongs to the technical field of chip processing, and more specifically relates to a zoom lens and wire bonding equipment. Background technique [0002] Wire bonding (Wire Bonding) is a process that uses heat, pressure, ultrasonic energy, etc. to tightly weld metal leads to substrate pads. In the wire bonding process in the chip manufacturing industry, it is usually necessary to use a wire bonding machine to complete. The wire bonding machine contains a zoom lens, which is used to collect images of the chip so that the chip can be soldered accurately. [0003] In the prior art, the most common zoom lens uses a stepping motor or a servo motor as power, and then drives the zoom lens barrel to move forward and backward through mechanical transmission components such as belts, gears or screw rods. The zoom lens barrel is installed on a sliding guide rail or a Slip fit on conduit. [0004] In addition, there is also a zoom lens that uses...
