Description

Technical Field

[0001] The utility model relates to the technical field of detection light sources, and particularly relates to a roll type detection light source. Background Art

[0002] For detecting electrode foils, currently ordinary instruments are used. The main detections include whether there are damages or holes on the electrode foils and whether there are scratches on the coating. The existing technology uses ordinary linear light sources. The problems are as follows: When the light of the light source irradiates on the electrode foil, as the electrode foil moves forward continuously, the electrode foil at the detection part is suspended, so the electrode foil will keep jumping, resulting in a decrease in detection accuracy and even sometimes a blurred detection situation. Content of the Utility Model

[0003] The purpose of the utility model is to overcome the above-mentioned defects in the prior art and provide a roll type detection light source, which can accurately detect the electrode foil and will not generate errors due to the jumping caused by the suspended movement of the electrode foil.

[0004] To achieve the above purpose, the utility model provides a roll type detection light source, including:

[0005] A light source main seat, the light source main seat includes two symmetrically arranged side plates, both ends of the two side plates are respectively connected with a first roll fixing seat and a second roll fixing seat, there are connecting parts on the first roll fixing seat and the second roll fixing seat, and a light outlet is formed on the two side plates;

[0006] A linear light source assembly fixed on the two side plates, an air cooling structure is arranged on the linear light source assembly, and a condenser rod is arranged between the linear light source assembly and the light outlet;

[0009] Further, the linear light source assembly includes a heat dissipation base and a light source circuit board which are fixedly connected in sequence from top to bottom, and both ends of the heat dissipation base are respectively detachably connected with the first roll fixing seat and the second roll fixing seat. The heat dissipation base dissipates heat from the light source circuit board.

[0010] Further, the air-cooling structure includes cooling air holes disposed in the heat dissipation base. The cooling air holes penetrate through the heat dissipation base, and plug screws are provided at two openings of the cooling air holes. Air inlets and air outlets are formed in the upper sides of two ends of the heat dissipation base, and heat dissipation air pipes are respectively connected to the air inlets and the air outlets. The two ends of the cooling air holes are blocked by the plug screws to form a closed air passage. The external air source and the air inlets / air outlets are connected by the heat dissipation air pipes, so that the cooling air source can enter the cooling air holes from the air inlets, realizing the heat exchange between the cooling air source and the heat dissipation base, and finally the hot air is discharged from the air outlets to achieve the cooling effect.

[0011] Further, a fixed end plate is fixedly connected to each of the first roller fixing seat and the second roller fixing seat. Two ends of the heat dissipation base and two side plates are connected to the fixed end plate.

[0012] Further, stepped mounting portions are formed in upper ends of the two side plates. Two side wings of the heat dissipation base extend outwards to form clamping portions, and the clamping portions are clamped on the stepped mounting portions. The stepped mounting portions can support the heat dissipation base, increasing the working stability of the linear light source assembly.

The linear light support frame is closely attached above the heat dissipation base, and a variety of uniformly distributed heat dissipation holes are provided on the linear light support frame.

[0014] Further, first grooves are formed on the two side plates. Two sides of the light collecting rod extend to form first clamping edges, and the first clamping edges are inserted into the first grooves. The insertion method makes the installation more convenient and saves costs.

[0015] Further, a second groove is formed on an inner side wall of the light outlet, and a transparent plate is clamped on the second groove. An LSD film is provided on the transparent plate. The LSD film can make the light of the light source emit uniformly.

The synchronous shaft is connected with the second bearing to achieve rotation. The encoding roller abuts against the outer surface of the transparent diffusion cylinder to achieve synchronous rotation of the two. Adding an encoder can record and control the precision of the rotation of the roller shaft and the movement of the electrode foil.

[0018] Compared with the prior art, the present utility model has the following advantages: The present utility model is composed of a linear light source component, a transparent diffusion cylinder in a cylindrical structure, a connecting bearing, etc. While the outer transparent diffusion cylinder rotates, the internal linear light source component always remains perpendicular in one direction and remains unchanged.

[0019] When detecting the electrode foil, the electrode foil can be tangent to the surface of the transparent diffusion cylinder. While the electrode foil moves forward, it drives the transparent diffusion cylinder to rotate together. At the same time, the internal linear light source component can detect the electrode foil passing through the tangent contact with the transparent diffusion cylinder, so that the electrode foil can be accurately detected, and errors will not occur due to the jumping of the electrode foil during suspended movement.

[0020] In addition, an encoder can be added on one side of the roller shaft according to the project requirements, so as to record and control the precision of the rotation of the roller shaft and the movement of the electrode foil. Description of the Drawings
