Technical Field

The utility model relates to a little C plane degree automatic measuring equipment of cell-phone center curved surface screen.

Background

The traditional production and operation mode depends on labor cost and scale advantages more, but with the continuous rise of labor cost in recent years, the traditional production and operation mode faces competitive pressure caused by external environment change and operation pressure caused by industry environment change. In addition, the process change period of consumer electronics products such as smart phones is shortened day by day, the product precision is higher and higher, manual operation often cannot meet the process requirements, and new processes and new equipment are urgently required to be developed to meet the production process requirements.

Automated factories are also a trend in the current times of industrial development. With the technical innovation and the change of market demands, the mobile phone structural part has the characteristics of diversified materials, less models and large amount of models. The small C flatness of the curved screen of the traditional middle frame of the mobile phone is detected by using a feeler gauge and a platform, so that three defects of appearance are easily caused, the measuring time is long, the efficiency is low, about 15S is required for measuring 1 product on average, and the misjudgment proportion exists in artificial measurement. The optical coupler measuring scheme is used, limitation is too large, the optical coupler can be installed only in the Z direction size of 1.5MM or more to the depth of a shell bin, the optical coupler is not suitable for a curved screen mobile phone middle frame, in addition, the clearance gauge measurement and the optical coupler measurement both adopt a point location measurement method, local position leakage risk exists, and poor inflow of the optical coupler to a client side is caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the not enough of above-mentioned current device, provide cell-phone center curved surface screen little C plane degree automatic measuring equipment, efficient fast, the measured data rate of accuracy is high, measures the face covering product around, does not have local position leakage risk.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

cell-phone center curved screen little C plane degree automatic measuring equipment, including the platform bottom plate in frame and the frame, be fixed with the light source in the middle of the platform bottom plate and examine the utensil, examine that the utensil is located the light source top and have the clearance with the light source, examine and seted up a plurality of light traps on the utensil, platform bottom plate distributes all around has the camera module of a certain amount. The mobile phone middle frame is placed on the checking fixture, the light source is turned on, light irradiates the mobile phone middle frame from the light transmission groove, the camera module captures the Z-direction size of reflected light again by applying the light reflection principle, and whether the flatness of the product reaches the standard is calculated.

Preferably, the number of the light transmission grooves is four, and two long grooves and two short grooves form a rectangle.

Preferably, camera module is fixed with two module curb plates including fixing the module bottom plate on the platform bottom plate on the module bottom plate, is equipped with the camera of erectting through the module diaphragm between two module curb plates. Wherein, the camera adopts a CCD camera.

Preferably, the module bottom plate, the module side plates and the module transverse plate are respectively provided with a strip-shaped hole. The strip-shaped holes are in XYZ three directions, and the front and back, left and right, and up and down positions of the camera can be adjusted through the strip-shaped holes.

Preferably, two are longer the camera module quantity in the light trap outside is two, and two are shorter the camera module quantity in the light trap outside is one.

Preferably, the camera module further comprises a housing with an opening at the inner side, so that the camera module plays a role in protection.

Preferably, the bottom of the frame is provided with a caster wheel and a foot cup assembly which are used for moving and positioning the frame and the mechanism on the frame.

The beneficial effects of the utility model reside in that: the utility model discloses a measuring equipment is efficient fast, and the average every PCS time of automatic measurement is 6S (including getting the time of putting), and the measured data rate of accuracy is high, adopts CCD to measure within the reading precision 0.001MM, measures the face and covers the product, does not have local position leakage risk all around, still reduces outward appearance three in addition and hinders.
