Background technology
With the development of vision technique and the raising to product quality requirement, performance and producing line of the people to mobile phone Camera
Testing efficiency proposes increasingly higher demands.During the production and assembly of mobile phone, it is (including clear to Camera performances to need
Degree, stabilization function etc.) it measures.Camera jitter test toolings become essential part in production line test；
The purpose of Camera test fixtures is to improve the design of production line testing efficiency.
In order to meet the requirement of visual test, also for preferably to the stringent performance survey of mobile phone Camera dither functions progress
Examination, while the actual demand of production line test is better adapted to, there is an urgent need to design Camera dither functions test fixtures；
Invention content
The object of the present invention is to provide a kind of test devices and its test method for Camera jitter tests, to meet
The actual demand of production line test, preferably tests mobile phone Camera functions；
The purpose of the present invention is be achieved through the following technical solutions：
A kind of test device and its test method for Camera jitter tests, including rotary electric machine and fixed fixture,
Translation motor and fixed fixture, translation lead screw, mobile phone support plate, lower support plate, mobile phone fixing press claw and cylinder, USB modules and cylinder,
Earphone module and cylinder, bottom plate and upper support plate.The distribution of two mobile phone symmetrical expressions, the axis of rotation and two mobile phone angles of inclination
45 ° of angle, be it is characterized in that：The Camera of two mobile phones can be tested simultaneously, and can be simultaneously to Camera
It is tested simultaneously in X, Y both direction.
Entire test device is carried by rotary electric machine and fixed fixture, translation motor and fixed fixture, translation lead screw, mobile phone
Plate, lower support plate, mobile phone fixing press claw and cylinder, USB modules and earphone module and cylinder, bottom plate, upper support plate are constituted.Pass through rotation
Motor and horizontal motor can be moved into row jitter test to the rotation peace of mobile phone Camera simultaneously；
The advantage of the invention is that：

Specific implementation mode
The present invention is described in further detail with reference to the accompanying drawings and examples；
The present invention is provided to the test device of Camera jitter tests and its test method, the method is：PLC is sent out
Control instruction, a spindle motor is sent to by servo-driver, realizes rotation shake；It is sent to two axis by servo-driver
Motor realizes translation shake.During two for rotating and translating, difference closing hand phone Camera stabilization functions and opening hand
Machine Camera stabilization functions, shoot two groups of photo comparison's analyses, and the data of test analysis are stored in the ends PC；
The specific connection relation of the Camera test devices is as follows：
Rotary electric machine and its fixed fixture are fixed on above lower support plate, the upper support plate of jig part connection, drive mobile phone together with
Entirely upper support plate rotates together；Mobile phone support plate, USB modules and cylinder, earphone module and cylinder, mobile phone fixing press claw and cylinder are all
It is fixed on support plate；Translation motor and its jig are fixed on substrate, and jig part is connected with lower support plate, drive entire
Plate part is downloaded to be translated；Lower support plate is connected by lead screw with bottom plate, to keep the stability of translation；When starting test,
USB modules are connected with mobile phone with earphone module by cylinder automatically, and cylinder drives claw to push, fixed mobile phone；Pass through bottom plate handle
Whole device is fixed in babinet；
Embodiment：
The length of entire Camera test devices is 650mm, width 190mm, height 197mm, and material is aluminium alloy, surface
Aoxidize black processing；
During the use of Camera test devices, two mobile phones are put into mobile phone support plate simultaneously first, start to survey
When examination, USB modules, earphone module connect mobile phone automatically, and mobile phone claw pushes fixed mobile phone automatically, and then whole device is automatic
It is pushed into babinet.When starting test, a pictures are shot in stationary state first, then by instructing control PLC by watching
Driver is taken, the rotary electric machine of an axis is allowed to start to carry out rotation shake according to the sinusoidal manner of intrinsic frequency, fixed swing angle,
In this process, the stabilization function of closing hand phone Camera shoots a photo, then opens the camera of mobile phone Camera
A photo is shot, two photos are respectively calculated, and comparative analysis obtains data；After shooting process, sent by PLC
Control instruction, allows the motor stalls of an axis, and returns to initial position.Then PLC sends control instruction, passes through another
Servo-driver allows the translation motor of two axis to start to work, and entire translation stage is made to start according to intrinsic frequency, fixed translation amplitude
Sinusoidal manner carries out translation shake, and in this process, the stabilization function of closing hand phone Camera shoots a photo, then beats
The camera for opening mobile phone Camera shoots a photo, and two photos are respectively calculated, and comparative analysis obtains data；It shot
After journey, control instruction is sent by PLC, allows the motor stalls of two axis, and returns to initial position.Rotation shake and
The end value that translation shake is tested twice, carries out judging whether qualification according to the thresholding of setting；After test, entire test dress
It sets and is removed from babinet, USB modules, earphone module and mobile phone push down automatic release, then replace mobile phone, are surveyed next time
Examination.
