Description

Technical Field

[0001] The utility model relates to the technical field of shield cover production, in particular to a shield cover detection device. Background Technique

[0002] At present, shield covers have been widely used in various electronic products, mainly applied to fields such as mobile phones and GPS (Global Positioning System). To achieve a better shielding effect, higher requirements are imposed on the flatness of the bottom surface of the side wall of the shield cover. Therefore, before leaving the factory, the flatness of the bottom surface of the shield cover must be detected to sort out qualified and unqualified products. At present, most shield cover detection devices on the market generally use a shape profile measuring instrument for detection. However, such equipment can only detect structures visible to the naked eye and cannot measure tiny concave structures on its end surface. Especially for products with smaller sizes, the detection accuracy is insufficient. Content of the Utility Model

[0003] The purpose of the utility model is to provide a shield cover detection device to solve the technical problems in the background technique.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions:

An installation hole is provided in the positioning plate, and the installation hole penetrates through the upper and lower ends of the positioning plate. The shape of the installation hole matches the outer shape of the shield cover. Along the inner wall of the installation hole, several support arms with the same structure are provided to support the shield cover.

The second support part is at the other end of the first support part and its thickness is less than that of the first support part. The bottom end surface of the second support part is flush with the bottom end surface of the first support part. The step formed by the difference in the top end surfaces of the first support part and the second support part is used to place the shield cover.

[0007] The Y-axis driving member includes a base, a motor, and a screw rod. The motor is installed on one side of the base and is drivingly installed with the screw rod. A nut is threadedly connected to the screw rod, and the nut is fixedly installed with a connecting plate. The 3D line laser sensor is fixed above the connecting plate.

[0015] The 3D line laser sensor 1 is located below the positioning plate 3. The 3D line laser sensor 1 is displaced back and forth below the positioning plate 3 by the Y-axis driving member 2. There is an installation hole 301 in the positioning plate 3, and the installation hole 301 runs through the upper and lower ends of the positioning plate 3.
