Problems solved by technology

[0002] With the improvement of people's living standards, electronic devices can be seen everywhere in people's lives, such as laptops, mobile phones, tablet computers, etc. Therefore, more manpower and material resources are needed in the processing of electronic devices to speed up production, but The production of an electronic device includes several links and the manufacturing and testing of many parts; After the shell is formed; due to material properties, craftsmanship, etc., the notebook shell will also warp, and it needs to be manually shaped and then manually checked with a feeler gauge to check whether the flatness of the shell is qualified; Accuracy, low efficiency, high rework rate and other problems, which directly lead to the most direct consequences of high cost and low benefit

Embodiment 1

[0044] like figure 1 As shown, the present invention discloses a flatness detection device, which is used for the flatness detection of an electronic equipment casing, including a cabinet 1, a laser sensor 3, a plane displacement mechanism, a quick-installation fixture 4, a control unit and other components.

[0045] There is an operating table 103 above the cabinet 1; fences are respectively provided on the front side and the left and right sides of the operating table 103; an air pressure output mechanism is arranged in the cabinet 1, and the air pressure output mechanism is mainly vertical cylinder 413 and The expansion and contraction of the transverse cylinder 408 is controlled; the bottom of the cabinet 1 is provided with a plurality of rollers 101 and foot cups 102 .

[0046]A detachable quick-installing fixture 4 is arranged in the middle position on the operating table 103. The function of the quick-installing fixture 4 is to fix the housing of the electronic equipmen...

Embodiment 2

[0054] Since the quick-mounting fixture 4 is being replaced or used, it is likely that the plane where the quick-mounting fixture 4 is located is inclined to the plane track where the laser sensor 3 moves. In order to solve this problem without manual adjustment, this solution provides Leaving the following its detection method, which includes the following steps:

[0055] S1: Establish a coordinate system with the long side of the shell of the electronic equipment to be tested as the X-axis direction, the short side as the Y-axis direction, and the set point as zero;

[0056] S2: Select two test points with the same Y-axis coordinates on the base plate 404, record the X-axis coordinates X1 and X2 of the two test points; read the height data Z1 and Z2 obtained by the laser sensor 3 on the two test points; Establish the correction parameter α:

[0057] α=(Z 2 -Z 1 ) / (X 2 -X 1 );

[0058] S3: The control unit corrects the X-axis direction parameter of the measured data acc...

Abstract

The invention relates to a flatness detection device and a detection method thereof, belonging to the field of electronic equipment manufacturing, comprising: a cabinet with an operating platform above the cabinet; a laser sensor disposed above the quick-installation jig and capable of detecting The distance from the housing of the electronic equipment; the plane displacement mechanism is arranged on the operating table and can control the movement of the laser sensor in the plane trajectory, and the plane trajectory exceeds the area where the housing of the electronic equipment is located; the quick-loading fixture is set It is on the operating table and can fix the shell of the electronic equipment; the quick-installation jig includes a bottom plate and a longitudinal telescopic mechanism and a horizontal telescopic mechanism arranged on the bottom plate, and the two telescopic mechanisms respectively include a retractor, a slider and a limiter. The position block, the retractor is connected and pushes the slider to move and cooperates with the limit block to fix the electronic equipment casing vertically or horizontally. This solution solves the problems of low accuracy and low efficiency in the existing manual flatness detection.

Description

technical field [0001] The invention relates to a flatness detection device and a detection method thereof, belonging to the field of electronic equipment manufacturing, in particular to the field of notebook computer manufacturing. Background technique [0002] With the improvement of people's living standards, electronic devices can be seen everywhere in people's lives, such as notebook computers, mobile phones, tablet computers, etc. Therefore, more human and material resources are required in the processing of electronic devices to speed up production, but The production of an electronic device includes several links and the production and testing of many components; for example, in the production process of notebook casings, after the thin aluminum plate is stamped and formed, plastic parts are installed through processes such as dispensing and hot pressing, and the production process is completed. After the shell is formed; due to material characteristics, craftsmanshi...
