Description

Technical Field

[0001] This utility model relates to the field of hole detection technology, and in particular to a light source device for assisting in the imaging of honeycomb structure workpieces to investigate hole blockage. Background Technology

[0002] Honeycomb structures are widely used in many fields due to their unique properties, especially in the field of automotive exhaust treatment, where the honeycomb structure carrier is a key component of exhaust purification catalysts. However, during the production of honeycomb structure carriers, due to the complexity of the process, the channels are prone to deformation or blockage. Furthermore, blockage can also occur during catalyst preparation and coating processes. Additionally, during catalyst use, unburned fuel, engine oil, and particulate matter generated from fuel additives in engine exhaust can also cause channel blockage. All of these factors affect product performance and quality; especially when catalyst performance deteriorates, the presence or absence of channel blockage is crucial for analyzing the cause and determining responsibility.

[0003] To detect channel blockage, current technologies primarily rely on specialized optical equipment for imaging. While these devices offer some solutions, they suffer from several drawbacks: their bulky size makes them unsuitable for use in confined spaces; their high cost increases production costs; and their complex operation requires specialized technicians, hindering large-scale production applications. Furthermore, the small size of the cellular carrier channels restricts incident light, causing diffraction and resulting in bent and scattered light spots. The uneven surfaces within the channels also cause light reflection and scattering, producing additional brightness and unwanted halo effects. Strong light sources can also cause glare in the images. All these factors significantly complicate channel imaging.

[0004] In summary, there is an urgent need in the market for a compact, inexpensive, and easy-to-operate honeycomb structure hole-blocking imaging device to meet the needs of rapid and efficient production testing. Utility Model Content

[0042] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0043] Please see Figures 1 to 7It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0044] like Figures 1-3 As shown, this utility model provides a light source device for assisting in the shooting of a honeycomb structure workpiece to check for blocked holes, including an opaque housing 1, a light source 2 that provides brightness to the inside of the opaque housing 1, and a frosted film 4.

[0045] The upper surface of the opaque housing 1 is provided with a through hole for light to pass through and enter the interior of the honeycomb structure workpiece 7; the frosted film 4 is used to be disposed on the upper end face of the honeycomb structure workpiece 7.

[0046] Specifically, the honeycomb structure workpiece 7 in this application is a honeycomb structure catalyst carrier, and the honeycomb structure workpiece 7 has several through holes formed from the upper end face to the lower end face, such as... Figure 3 As shown.

[0047] In the above embodiments, the device can effectively reduce light interference and light scattering, clearly photograph the honeycomb structure workpiece 7 from above, clearly distinguish the edges of the channels, and easily, quickly, and intuitively determine the blockage status of the honeycomb structure workpiece 7, facilitating subsequent problem analysis. The light provided by the light source 2 enters the channels inside the honeycomb structure workpiece 7, illuminating the channels. The through-holes in the opaque housing 1 can be structures matching the lower end face of the honeycomb structure workpiece 7, structures with an area larger than the lower end face of the honeycomb structure workpiece 7, or even the entire upper surface of the opaque housing 1 can be a through-hole structure. The frosted film 4 can be made of PVC, PET, or PEVA, preferably a frosted plastic sealant film. Its frosted texture can scatter incident light, reduce specular reflection, and significantly reduce glare, light spots, and halos without affecting transparency. Furthermore, the frosted film 4 can also be further enhanced by adding an optical coating to make the light scattering more uniform, better controlling halos and glare. Specifically, the light source 2 can be an LED light source or a halogen lamp. The installation methods for light source 2 include, but are not limited to, the following: light source 2 can be fixed to the side wall or bottom of the opaque housing 1 using detachable connection methods such as screws or clips; alternatively, it can be selected as... Figures 1-3 The embedded installation shown is mounted on the side wall or bottom of the opaque housing 1.

[0048] In one specific embodiment, the thickness of the frosted film 4 is 0.1 to 0.5 mm.

[0049] During use, the illuminance on the lower end face of the honeycomb structure workpiece 7 is 500-1500 Lux. Illuminance is a physical quantity that describes the degree of illumination of the surface of an object by a light source. If the illuminance is too low, it will affect the identification of whether the holes of the honeycomb structure workpiece are blocked. If it is too high, it will produce glare or reflection interference, affecting the accuracy of detection.

[0050] In one specific embodiment, the light source 2 is disposed on the side and / or lower surface of the opaque housing 1, such as... Figures 1-3 As shown, the light source 2 is located on the side of the opaque housing 1.

[0051] In a like Figure 4 In the specific embodiment shown, the opaque housing 1 has a hexahedral structure.

[0052] In a like Figure 3 In the specific embodiment shown, a reflective layer 11 is provided on the inner side of the opaque housing 1. The main function of the reflective layer 11 is to increase the light intensity entering the honeycomb structure workpiece 7, thereby improving the brightness during shooting and ensuring clear imaging. Specifically, the material selection of the reflective layer 11 is diverse and flexible to meet the needs of different application scenarios.

[0053] In a more specific embodiment, the reflective layer 11 is selected from one or more of a metallic reflective layer, optical glass, and a reflective coating. Metallic reflective layers, such as those made of aluminum or silver, possess excellent reflective properties, effectively increasing light intensity. Optical glass, through special optical design, achieves efficient light reflection. Reflective coatings, such as those containing glass microspheres or microprism structures, reflect light back to the direction of the light source 2 through special optical principles, exhibiting high reflectivity. In practical applications, the reflective layer 11 can be selected from reflective plates, reflective fabrics, or directly coated onto the inner wall of the opaque housing 1 to form a reflective coating. For example, by setting a metallic glossy layer and a microsphere layer on a base fabric to prepare a reflective fabric, excellent reflective effects are achieved. Furthermore, the reflective coating can also be designed with a multi-layer structure, such as setting a microstructure layer and the reflective layer 11 on a substrate layer, to further improve reflective performance. Those skilled in the art can rationally select the material and form of the reflective layer 11 according to actual needs and the usage environment to adapt to different usage scenarios and cost budgets.

[0054] In a like Figures 1-4 In the specific embodiment shown, the device further includes a light-transmitting support plate 5 for supporting the honeycomb structure workpiece 7. The light-transmitting support plate 5 covers the through-holes, ensuring that light can pass smoothly and enter the internal channels of the honeycomb structure workpiece 7. The light-transmitting support plate 5 has a dual function: on the one hand, it allows light to pass through itself into the internal channels of the honeycomb structure workpiece 7, providing the necessary illumination conditions for the observation of the channels; on the other hand, it also supports and carries the honeycomb structure workpiece 7, ensuring that the workpiece remains stable during the inspection process, facilitating accurate observation of the channel blockage of the honeycomb structure workpiece 7. To meet the above functional requirements, the material of the light-transmitting support plate 5 needs to have good light transmittance and a certain mechanical strength. In this embodiment, the material of the light-transmitting support plate 5 can be a transparent resin plate or a glass plate. Transparent resin plates are lightweight and impact-resistant, suitable for applications requiring portability and high impact resistance; while glass plates have high transparency and good optical performance, suitable for applications requiring high imaging quality. Those skilled in the art can reasonably select the specific material of the light-transmitting support plate 5 according to the actual application requirements and the characteristics of the workpiece.

[0055] In a like Figures 1-4In a more specific embodiment shown, the device further includes a light-shielding plate 6, which is disposed close to the upper surface of the supporting light-transmitting plate 5 and has a light-transmitting hole 61 that matches the lower end face structure of the honeycomb structure workpiece 7. The light-shielding plate 6 is used to block the light transmitted from the supporting light-transmitting plate 5, allowing only the light passing through the light-transmitting hole 61 to pass through. Its function is to ensure that only light from a specific area can pass through, thereby avoiding interference from the scattering of other light rays during the observation or shooting process. The material of the light-shielding plate 6 is diverse and flexible to meet the needs of different application scenarios. In this application, the material of the light-shielding plate 6 includes, but is not limited to, light-shielding PC board, black pigment coating material, and carbon nanotube composite material. These materials all have excellent light-shielding performance and can effectively block light, ensuring that the light passing through the light-transmitting hole 61 is clearly visible. In addition, in different embodiments, the light-shielding plate 6 can also be made of other materials such as opaque cardboard. These materials can also achieve the light-shielding function, and are low in cost and easy to process and replace.

[0056] In a like Figures 1-4 In a further specific embodiment shown, the light-shielding plate 6 completely covers the carrier light-transmitting plate 5 to completely block the light transmitted from the carrier light-transmitting plate 5, allowing only the light passing through the light-transmitting hole 61 to pass through, thereby avoiding interference from the scattering of other light rays during the observation or shooting process.

[0057] In a further specific embodiment, the thickness of the light-shielding plate 6 is 0.5 to 1.5 cm.

[0058] In a like Figures 1-3 In the specific embodiment shown, the device further includes a light-shielding sleeve 3, which is used to cover the honeycomb structure workpiece 7 to prevent light leakage from the light-transmitting hole 61. The light-shielding sleeve 3 can effectively reduce light interference and avoid halos and spots caused by light scattering, thereby significantly improving the clarity and image quality of the captured photos. The structure and material of the light-shielding sleeve 3 are diverse and flexible to meet the needs of different application scenarios. In this embodiment, the light-shielding sleeve 3 includes, but is not limited to, light-shielding cloth. As a preferred light-shielding material, light-shielding cloth has good light-shielding performance and flexibility, and can closely fit the periphery of the honeycomb structure workpiece 7 to ensure that light only enters the interior of the workpiece through predetermined channels. The material of the light-shielding cloth is preferably black velvet. In addition to black velvet, the light-shielding sleeve 3 can also be made of other materials with similar light-shielding performance, such as opaque plastic film, black rubber material, carbon fiber composite material, etc. These materials can also achieve the light-shielding function, and may have better performance in certain specific scenarios. Those skilled in the art can reasonably select the specific structure and material of the light-shielding sleeve 3 according to the actual application requirements and the characteristics of the workpiece.

[0059] In a like Figures 1-3In a further specific embodiment shown, the light-shielding sleeve 3 is disposed at the matching position between the light-transmitting hole 61 and the lower end face of the honeycomb structure workpiece 7, and is used to block the light exposed from the gap at the matching position, allowing only the light passing through the light-transmitting hole 61 to pass through, thereby avoiding the scattering of other light rays from interfering with the observation or shooting process.

[0060] This embodiment provides a device including an opaque housing 1, a light source 2, a light-shielding sleeve 3, a frosted film 4, a light-transmitting support plate 5, and a light-shielding plate 6. The light source 2 is disposed on the side and / or lower surface of the opaque housing 1. A reflective layer 11 is provided on the inner side of the opaque housing 1. The light-transmitting support plate 5 covers the through hole of the opaque housing 1. The light-shielding plate 6 covers the upper surface of the light-transmitting support plate 5. A honeycomb structure workpiece 7 is placed in the light-transmitting hole 61 of the light-shielding plate 6. The light-shielding sleeve 3 is fitted on the honeycomb structure workpiece 7 to prevent light leakage from the light-transmitting hole 61. The upper end surface of the honeycomb structure workpiece 7 is covered with the frosted film 4. In this embodiment, specifically, the honeycomb structure workpiece 7 is made of ceramic, with a circular end face, an end face diameter of 266.70 mm, a length of 127 mm, a mesh count of 400, and a wall thickness of 4.5 mils; the light source 2 has an opaque housing on its side; the light-transmitting support plate 5 is made of transparent resin board; the light-shielding plate 6 is made of opaque cardboard with a thickness of 0.5 cm; the light-shielding sleeve 3 is made of black velvet with a thickness of 0.5 mm; and the frosted film 4 is made of PVC film with a thickness of 0.1 mm.

[0061] After the equipment and the honeycomb structure components are assembled, the operating steps are as follows:

[0062] (1) Turn on light source 2;

[0063] (2) Place the camera above the honeycomb structure workpiece 7 and shoot the holes of the honeycomb structure workpiece 7 downwards with the lens.

[0064] Take pictures as Figures 5-6 As shown, the edges of the holes can be clearly distinguished. Holes that appear bright when light passes through are considered unblocked, while holes that appear black when light cannot pass through are considered blocked.

[0065] In step (1), the frosted film 4 is adjusted to cover only half of the upper surface of the honeycomb structure workpiece 7, and the rest is the same as in the above embodiment. As a comparative example of the above embodiment, the channels of the honeycomb structure workpiece 7 are photographed again, and the images are as follows. Figure 7As shown, the half covered by the frosted film 4 allows the edges of the channels to be distinguished. Channels that appear bright when light passes through are considered unblocked, while channels that appear black when light cannot pass through are considered blocked. However, the other half, without the frosted film 4, shows a halo effect, making it impossible to distinguish the channel edges and thus impossible to determine whether a blockage has occurred. This demonstrates that adding the frosted film 4 significantly reduces the appearance of halo effects, allowing for clear identification of the channel edges when photographing the honeycomb structure workpiece 7, thus providing a simple, quick, and intuitive way to determine the blockage status of the honeycomb structure workpiece 7.

[0066] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
