Description

Technical Field

[0001] This invention relates to the field of laboratory equipment technology, and more specifically to an auxiliary lighting device for the punching area of ​​an electrode punching machine. Background Technology

[0002] In battery material research and related experiments, electrode punching machines are often used to punch coated electrode materials to obtain circular or other shaped electrode sheets.

[0003] The existing electrode punching machine has the following problems in the punching process: The punching area is located inside the machine body or in a structurally obstructed location, where there is insufficient light, making it difficult for the operator to clearly observe the position of the electrode. An unreasonable light direction can easily produce shadows or reflections, affecting the judgment of the punching boundary; Dust, electrode material debris, and metal foreign objects are generated during the punching process. If the light source is directly exposed, it is easily contaminated. The electrode sheet, after being punched, falls from above and may block the light source, affecting subsequent observation.

[0004] The aforementioned problems lead to reduced utilization of electrode materials, and the punching edges are prone to gaps or misalignment, affecting experimental quality.

[0005] Therefore, it is necessary to provide a lighting device with a reasonable structure that is easy to use stably for a long time. Summary of the Invention

[0006] Purpose of the invention: The purpose of this invention is to provide an illumination device for an electrode punching machine. By reasonably setting the light source, the light transmission window, and the electrode drop guide cone, the punching area can obtain stable illumination, while preventing dust and electrode sheets from blocking the light, thereby improving the accuracy and stability of the punching operation.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: like Figure 1 As shown, a lighting device for a laboratory electrode punching machine includes: The light source is mounted on a light source base, which is located at the bottom of the photomask. The upper surface of the light source base is provided with a coating or metal film that has reflective or diffuse reflection properties. The photomask is arranged around the light source and can be in the shape of an inverted trumpet, a trumpet, a straight cylinder, etc. The inner wall of the photomask is provided with a reflective or diffuse reflection coating surface. A light-emitting aperture is positioned at the center of the upper part of the photomask; An electrode drop guide cone is positioned above the light-transmitting window to guide the electrode to fall onto the outer periphery of the lampshade, preventing the electrode from falling onto the light-transmitting area.

[0008] The light emitted by the light source is reflected or guided by the photomask and then shines upward through the light-perforated window to illuminate the punched area; The light-perforated window is used to allow light to pass through while blocking dust, electrode material debris, and metal foreign objects from entering the interior of the photomask; The electrode drop guide cone is used to deflect the electrode sheet that falls off after punching away from the light-passing window, thereby preventing the electrode sheet from blocking the light-emitting position.

[0009] The photomask structure can be any of the following: conical, horn-shaped, contraction, expansion, or cylindrical, with the aim of improving light utilization efficiency or optimizing the light output direction.

[0010] The light-transmitting window can be made of glass, transparent plastic, or other light-transmitting materials.

[0011] The electrode drop guide cone is a cone-shaped or cone-like structure, which is a guide made of multiple fine filaments. It is used to guide the electrode to slide sideways, but will not significantly affect the upward light.

[0012] The light source can be a single or multiple visible light emitting units and is powered by a DC power supply, which can be a battery, a rectified power supply or other power supply device. Beneficial effects

[0013] Compared with the existing punching machine structure that adopts "blind cutting", the present invention has the following advantages: The light source is positioned below the punch and emits light upwards, which can effectively illuminate the punching area and improve visibility; By setting up a photomask structure, light utilization efficiency is improved and ineffective light loss is reduced; The light-permeable window can prevent dust and foreign objects from entering the photomask, ensuring that the device can be used stably for a long time; The electrode drop guide cone can prevent the punched electrode from blocking the light-emitting position and ensure continuous illumination; The overall structure is simple, easy to install and maintain, and suitable for electrode punching machine environments such as laboratories. Attached Figure Description Figure 1 This is a schematic diagram of the overall structure of the device of the present invention. Figure 2 This is a schematic diagram showing the position of the device of the present invention when used in conjunction with the upper and lower dies of the electrode punching machine. Detailed Implementation

[0014] The present invention will be described in conjunction with the accompanying drawings.

[0015] like Figure 2 As shown, the present invention includes a light source, a photomask, a light-permeable window, and an electrode drop guide cone.

[0016] The light source is installed below the punched hole, with its light emission direction facing the punched hole. The light source can be a single or multiple light-emitting units and is powered by a DC power supply.

[0017] A photomask structure is installed around the light source to reflect or guide the light. The photomask can adopt different geometric structures to adapt to different installation spaces.

[0018] The top of the photomask has a light outlet, and a light transmission window is provided at the light outlet. The light transmission window is made of transparent material to prevent dust and metal foreign objects from entering the interior.

[0019] An electrode drop guide cone is installed above the light-passing window. The electrode drop guide cone can be a conical component or a filamentous structure, used to guide the electrode sheet that falls after punching to slide laterally and avoid covering the light-passing window.

[0020] The above structural combination ensures stable illumination in the punching area during the punching process, improving operational accuracy.

[0021] This invention is not limited to the specific embodiments described above. Any equivalent substitutions made without departing from the technical concept of this invention shall fall within the protection scope of this invention.
