Description

Technical Field

[0001] This utility model relates to electroplating inspection equipment, and in particular to a visual inspection device for electroplating strips. Background Technology

[0002] With the miniaturization of electronic products, integrated circuit components are widely used. Connections between adjacent components are typically made using terminals. To ensure the electrical performance and corrosion resistance of these terminals, precious metals such as gold and silver are usually electroplated onto the electrical connection surfaces. To improve electroplating efficiency, the terminals are usually fed into the electroplating equipment along with the material strip. During the electroplating process, abnormalities such as deformation and incomplete plating often occur. The traditional method is to inspect the entire roll of material after electroplating, but this method makes it difficult to detect abnormalities in a timely manner, resulting in more waste and increased costs.

The stabilizing adjusting screw is rotatably connected to the stabilizing lifting base, and the stabilizing lifting seat is threadedly engaged with the stabilizing adjusting screw.

[0007] As a further improvement to this design, the stable lifting seat is provided with two material support rollers, and each material support roller is provided with a clamping roller on each side. The material support rollers are arranged along the direction of material belt travel, that is, they are in contact with the two clamping rollers on the same side of the material belt. The distance between the clamping rollers on the side of the material belt facing the supplementary light source is greater than the distance between the clamping rollers on the other side.

[0008] As a further improvement to this design, both the material support wheel and the material clamping wheel are ceramic wheels.

[0009] As a further improvement to this design, the fill light strip extends along the edge of the front opening of the light source box, the reflector is a semi-reflective mirror, and the main fill light is provided in the light source box behind the reflector.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments. The illustrative embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0021] Example: A visual inspection device for electroplating strips includes a base plate 1, a strip stabilizing mechanism 3 mounted on the base plate 1, and a visual inspection camera assembly 5 mounted on the strip stabilizing mechanism 3. The strip stabilizing mechanism 3 includes a stabilizing lifting mechanism 30, a material support roller 32 mounted on the stabilizing lifting mechanism 30, and clamping rollers 31 mounted on both sides of the material support roller 32. The visual inspection camera assembly 5 includes a three-axis fine-tuning platform 50 and a supplementary light source mounted on the three-axis fine-tuning platform 50. The light source 51 and the CCD inspection camera 52 are provided. The light source 51 includes a light source box 510, an illumination strip 512 disposed at the front opening of the light source box 510, and a reflector 514 disposed inside the light source box 510. The top of the light source box 510 is provided with a top viewing window 511, and the front of the light source box 510 is provided with a front viewing window 513. The front viewing window 513 and the top viewing window 511 are covered with transparent glass. The detection port of the CCD inspection camera 52 is directly facing the top viewing window 511.

[0022] The aforementioned installation of a vision camera detection component on the electroplating equipment enables timely detection of abnormalities, prompting operators to address malfunctions promptly; the material belt stabilization mechanism 3 stabilizes the material belt 4, facilitating improved detection accuracy; and the supplementary light source 51 further enhances detection accuracy.

[0023] To improve the adaptability of the visual inspection camera assembly 5 to different material strips 4, the three-axis fine-tuning platform 50 is composed of three lead screw fine-tuning platforms, which facilitates the adjustment of the positions of the supplementary light source 51 and the CCD inspection camera 52. The lead screw fine-tuning platforms are commercially available parts, and the interconnection method adopts a conventional connection method.

[0024] The stabilizing lifting mechanism 30 includes a stabilizing lifting base 304, a stabilizing guide post 301 and a stabilizing adjusting screw 302 vertically mounted on the stabilizing lifting base 304, a stabilizing top plate 300 mounted on the top of the stabilizing guide post 301, and a stabilizing lifting seat 303 that slides up and down along the stabilizing guide post 301. The stabilizing adjusting screw 302 is rotatably connected to the stabilizing lifting base 304, and the stabilizing lifting seat 303 is threadedly engaged with the stabilizing adjusting screw 302. The stabilizing adjusting screw 302 allows for fine-tuning of the height of the adjusting clamping wheel 31 and the supporting wheel 32, making it suitable for material strips 4 of different heights and offering wide applicability.

[0025] To further stabilize the material belt 4, the stabilizing lifting seat 303 is equipped with two material support rollers 32, each with a clamping roller 31 on each side. The material support rollers 32 are arranged along the traveling direction of the material belt 4, meaning they are in contact with the two clamping rollers 31 on the same side of the material belt 4. To avoid affecting the detection field of the CCD inspection camera 52 and to further improve the stability of the clamping rollers 31 on the material, the spacing between the clamping rollers 31 on the side of the material belt 4 facing the supplementary light source 51 is greater than the spacing between the clamping rollers 31 on the other side.

[0026] To improve the service life of the material support wheel 32 and the clamping wheel 31, both the material support wheel 32 and the clamping wheel 31 are ceramic wheels.

[0027] In order to improve the uniformity of the light source irradiation of the material strip 4 and improve the accuracy of the detection, the supplementary light strip 512 extends along the edge of the front opening of the light source box 510, the reflector 514 is a semi-reflector, and the main supplementary light 515 is provided in the light source box 510 behind the reflector 514.

[0028] To facilitate automatic detection, the base plate 1 is also equipped with a material strip sensing assembly 2. The material strip sensing assembly 2 includes a sensing base plate 20, sensing guide posts 21 and a sensing adjustment screw 22 disposed on the sensing base plate 20, a sensing top plate 24 disposed on the top of the sensing guide posts 21, a sensing lifting seat 23 that slides with the sensing guide posts 21, and an optical fiber sensor 25 disposed on the sensing lifting seat 23. The sensing adjustment screw 22 is threadedly engaged with the sensing lifting seat 23. The sensing adjustment screw 22 facilitates adjustment of the height of the optical fiber sensor 25, enabling more precise sensing of the material strip 4.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
