Novel mobile phone camera module automatic test machine

Abstract

The invention provides a novel mobile phone camera module automatic test machine which comprises a control panel, a test area and a work machine frame, wherein a work table top and a keyboard support are arranged in the middle of the work machine frame. The test area comprises a test position and a test light source located above the test position, the test position is arranged on the work table top, the test position comprises a reset switch, a starting switch, a display signal device, a test main board, a tank chain, a product fixing mechanism, an X-Y horizontal-movement sliding platform, a light barrier, a sliding rail, a sliding sleeve and a limiting sensor, the sliding sleeve can freely slide on the sliding rail front and back, the X-Y horizontal-movement sliding platform is fixed on the sliding sleeve, and the test main board is fixed on the X-Y horizontal-movement sliding platform. Automatic test of a mobile phone camera module, comprising MTF test, stain test, damaged point test, noisy point test, VCM curve test, color uniformity and luminance uniformity test, and the like is ahieved through the novel mobile phone camera module automatic test machine. The novel mobile phone camera module automatic test machine is high in test efficiency, and suitable for modules of different pixel levels.

Description

technical field [0001] The invention relates to an automatic testing device for a camera module of a mobile phone, in particular to a novel automatic test machine for a camera module of a mobile phone. Background technique [0002] With the development of the mobile phone industry, a large number of mobile phones have begun to convert from non-smart phones to smart phones, so the demand for mobile phone cameras is also increasing. However, the production process of mobile phone camera modules is relatively long and the production process is complicated, resulting in that the quantity of shipments and the delivery date cannot meet the needs of customers. The most critical position that affects the shipment quantity and delivery date is the finished product inspection position. Due to the large number of test items and long test time, this position has become the biggest bottleneck in each process of production. Although a lot of manpower and semi-automatic testing machines ha...
