Description

Technical Field

[0001] This utility model relates to the field of precision instrument testing equipment technology, and in particular to a gel testing device for detecting gel impurities. Background Technology

[0002] In industries such as pharmaceuticals and biomaterials, quality control of gel products is crucial, and the detection of internal impurities is a key step in the production process. Currently, foreign matter detection in such translucent or transparent gel samples is mostly achieved through manual light inspection or automated inspection equipment based on machine vision. These methods rely on placing the sample at an appropriate imaging distance and providing effective background contrast to identify minute impurity particles.

[0003] Existing gel imaging devices often employ simple screw-lifting or whole-piece pad replacement methods to adjust the relative position between the sample and the imaging component. These structures may suffer from limited adjustment precision, insufficient ease of operation, or difficulty in fine-tuning. Furthermore, the fixation of the vessel (such as a culture dish) holding the gel sample on the detection platform, without an effective adaptive clamping mechanism, may lead to displacement during repeated placement or adjustment, affecting the consistency and reliability of the detection sequence.

[0004] Therefore, it is necessary to design a detection device that can quickly adjust the relative position between the sample and the imaging component. Utility Model Content

[0045] The embodiments of this utility model will be described in detail below.

[0046] This utility model discloses a gel detection device. The device utilizes the coordinated operation of a base 1, a scissor-type lifting mechanism 2 guided by an integrated chute and slider, a work plate 22 with elastic clamping arms 3, and an integrated background plate compartment 15 to facilitate the detection of gel samples. Details are as follows:

[0047] Figure 1 This is a schematic diagram of the three-dimensional structure of the gel detection device; Figure 2 A perspective view of the three-dimensional structure of the gel detection device; Figure 3 This is a front view of the gel detection equipment; Figure 4 Right view of the gel detection device.

[0048] The base 1, serving as the fundamental support structure of the equipment, is typically made of metallic materials such as aluminum alloy, cast iron, or carbon steel through casting, welding, or machining. Its function is to provide a stable mounting platform and accommodate other functional components. A first slide groove 11 is provided on the base 1. The first slide groove 11 guides and constrains the first slider 12, allowing it to slide smoothly along a predetermined trajectory. The cross-sectional shape of the first slide groove 11 can be rectangular or trapezoidal, and its length can be designed according to the lifting stroke requirements. The clearance between the first slider 12 and the first slide groove 11 can be controlled between 0.05mm and 0.2mm to ensure smooth sliding. In this embodiment, the first slide groove 11 is a continuous straight groove; in other embodiments, the first slide groove 11 can also be an arc-shaped groove or a curved groove with a specific contour. A cantilever frame 13 is also fixedly installed on the base 1. The cantilever frame 13 extends the installation position to suspend the detection camera 14, ensuring that the observation optical axis of the detection camera 14 is aligned with the working area. The detection camera 14 is mounted to the end of the cantilever 13 via bolts, clamps, or a quick-release mechanism. Its function is to acquire image information of the gel sample to be tested for analysis. An industrial camera can be used for the detection camera 14.

[0049] Additionally, a background plate compartment 15 is fixedly installed on the base 1 via bolts, welding, or integral molding. The background plate compartment 15 serves to centrally and systematically store various spare background plates. The compartment 15 contains multiple independent cavities arranged sequentially from top to bottom, specifically including a first storage cavity 151 for storing white background plates, a second storage cavity 152 for storing black background plates, and a third storage cavity 153 for storing grid-line background plates. This categorized storage design allows operators to quickly select a suitable background plate based on the optical characteristics of the gel sample and any debris. The background plates can be made of acrylic, frosted glass, or special plastics, with a thickness generally ranging from 1mm to 3mm. In this embodiment, there are two first storage cavities 151, two second storage cavities 152, and two third storage cavities 153; in other embodiments, the number of first storage cavities 151, second storage cavities 152, and third storage cavities 153 can be three, four, or other quantities, to meet storage capacity requirements in different scenarios. The dimensions of each storage cavity can be designed according to the background plate specifications.

[0050] The lifting mechanism 2 is mounted on the base 1 and its function is to precisely adjust the height of the working plate 22. The lifting mechanism 2 includes an adjustable bracket 21 and a working plate 22. A first cavity 220 is provided on the working plate 22, which provides an unobstructed field of view for the detection camera 14. The diameter of the first cavity 220 can be designed according to the size of the gel sample to be tested. In this embodiment, the first cavity 220 is a rectangular through hole; in other embodiments, the first cavity 220 can also be a square, circular, or other geometrically shaped through hole. On opposite sides of the first cavity 220 of the working plate 22, clamping arms 3 for holding the product to be tested are installed. A second slide groove 221 is provided below the working plate 22, and a sliding second slider 222 is installed in the second slide groove 221. The cooperation between the second slide groove 221 and the second slider 222 provides sliding constraint for the connection point between the adjustable bracket 21 and the working plate 22. The length of the second slide groove 221 is coordinated with the length of the first slide groove 11.

[0051] The adjustable support 21 is the core transmission component of the lifting mechanism 2, and it includes a first support rod 211 and a second support rod 212 that are hinged to each other. One end of the first support rod 211 is hinged to a fixed hinge seat pre-set on the base 1 by a pin, and the other end is hinged to a fixed hinge seat pre-set below the working plate 22 by a pin. One end of the second support rod 212 is hinged to the first slider 12 by a pin, and the other end is hinged to the second slider 212 by a pin. The cross-section of the first support rod 211 and the second support rod 212 can be designed as rectangular, circular or I-shaped, and the material can be stainless steel or aluminum alloy. By driving the first slider 12 to slide along the first slide groove 11, the included angle between the first support rod 211 and the second support rod 212 can be changed, thereby converting the horizontal linear motion of the first slider 12 into the vertical lifting motion of the working plate 22, and thus precisely adjusting the distance between the gel sample to be tested held by the clamping arm 3 on the working plate 22 and the detection camera 14. In this embodiment, the first support rod 211 and the second support rod 212 are straight rods with equal cross-sections; in other embodiments, the first support rod 211 and the second support rod 212 may also be rods with bent or curved profiles.

[0052] The first support rod 211 and the second support rod 212 are hinged together at the middle by a hinge pin, forming a hinge point. The diameter of the hinge pin can be designed from 8mm to 16mm depending on the load. The position of this hinge point affects the lever arm ratio and motion characteristics of the lifting mechanism. In this embodiment, the hinge point is closer to the end of the first support rod 211 that connects to the working plate 22, compared to the two ends of the first support rod 211. Specifically, the distance from the hinge point to the end of the first support rod 211 that connects to the working plate 22 is designed to be one-third of the total length of the first support rod 211. This proportional design makes the scissor-type bracket a force-saving lever system, which helps to reduce the external force required to drive the first slider 12 to slide. In other embodiments, this distance can also be one-quarter or two-fifths of the total length of the first support rod 211, etc., to adapt to different force-saving requirements and lifting stroke requirements.

[0053] The clamping arm 3 is a key component for securing the sample vessel. Each clamping arm 3 includes an outer cylinder 31 mounted on the working plate 22, an inner cylinder 32 slidably mounted within the outer cylinder 31, and a spring installed inside the outer cylinder 31. The two ends of the spring elastically abut against the bottom of the outer cylinder 31 and the inner end face of the inner cylinder 32, respectively. The outer cylinder 31 and inner cylinder 32 can be made of stainless steel or aluminum alloy, and the clearance between the inner cylinder 32 and the outer cylinder 31 can be controlled between 0.1 mm and 0.3 mm. Under the elastic preload of the spring, the inner cylinders 32 of the clamping arms 3 located on opposite sides of the first cavity 220 can extend towards each other, thereby achieving adaptive elastic clamping of the product to be tested placed on the working plate 22. To enhance clamping stability and protect the vessel, a rubber pad 33 is installed at the end of the inner cylinder 32 away from the outer cylinder 31. The rubber pad 33 is manufactured using injection molding, compression molding, or machining methods, and the material can be nitrile rubber, silicone rubber, or polyurethane rubber. In this embodiment, the thickness of the rubber pad 33 along the axial direction of the inner cylinder 32 is designed to be 5mm; in other embodiments, this thickness can also be different values ​​such as 6mm, 8mm, or 10mm to ensure that it has sufficient elastic deformation capacity and cushioning effect. A thicker rubber pad 33 can increase the contact area, making the clamping force distribution more uniform, while its elastic deformation can absorb vibration and reduce the risk of the vessel slipping.

[0054] Overall, the gel detection device in this embodiment employs a combination of a guiding structure consisting of a first groove 11 and a first slider 12, a scissor-type adjustable support 21 composed of a first support rod 211 and a second support rod 212, a working plate 22 with a first cavity 220 and an elastic clamping arm 3, and a background plate compartment 15 with integrated classification and storage functions. Due to the guiding mechanism of the sliding pair of the first groove 11 and the first slider 12, combined with the transmission principle of the scissor-type linkage mechanism, the height adjustment process is relatively smooth, reducing the shaking that may occur with traditional screw lifting. The elastic clamping arm 3, through the constant preload provided by the spring, can adapt to gel samples of different sizes, and its rubber pad 33 structure increases friction and provides cushioning protection. The multi-cavity classification design of the background plate compartment 15 enables orderly management of the background plates. This solution can, to a certain extent, achieve stable and precise adjustment of sample height, provide a reliable and flexible sample fixation method, and quickly adapt to different detection backgrounds. Through the coordinated work of each component, this device may have a positive effect on improving the convenience, stability, and efficiency of gel impurity detection operations.

[0055] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
