Description

Technical Field

[0001] This utility model relates to the technical field of gel imaging, and in particular to the technical field of ultraviolet light box components for gel imaging devices. Background Technology

[0002] Gel imaging systems are experimental instruments primarily used for the imaging and analysis of proteins and nucleic acids using gels. These systems use ultraviolet or white light sources to excite the sample. The imaging components of the system capture the emitted light through a specific wavelength filter to obtain an image. Then, the system's built-in image analysis software analyzes the acquired image to determine the detection result for the sample. A problem with existing gel imaging systems is their low level of automation. The ultraviolet lamp boxes are mostly manual, requiring manual operation of the lamp box, which reduces automation. Furthermore, manual operation of the ultraviolet lamp box carries the risk of excessive hand contact with the lamp box, potentially leading to additional contamination. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a UV light box assembly for a gel imaging device. The UV light box automatically enters and exits the device, has a high degree of automation, requires minimal contact with the UV light box, and does not pose an additional risk of contamination.

[0004] To achieve the above objectives, this utility model proposes a UV lamp box assembly for a gel imaging instrument, including a UV lamp box with a sample illumination area for irradiating samples, and an automatic loading / unloading mechanism for driving the UV lamp box to move laterally. The automatic loading / unloading mechanism includes a first guide rail, a synchronous belt, pulleys, and a drive motor. The UV lamp box has a first guide rail on its side or bottom for cooperating with the UV lamp box. The UV lamp box is mounted on the first guide rail. A synchronous belt is arranged in the same direction as the first guide rail. Pulleys are provided at both ends of the synchronous belt. A drive motor for driving its rotation is connected to any of the pulleys. The UV lamp box is fixedly connected to any position on the synchronous belt by a fixing member.

[0005] Preferably, a second guide rail is provided on the lower side or side of the synchronous belt, which is arranged in the same direction as the synchronous belt, and the fixing member is fixedly connected to the guide rail slider of the second guide rail.

[0006] Preferably, the first guide rail is a multi-segment drawer guide rail.

[0007] Preferably, the drive motor is an encoder motor or the drive motor has an encoder synchronously connected to its rotating shaft.

[0008] Preferably, the device further includes several positioning photoelectric sensors and several sensing sheets that cooperate with the positioning photoelectric sensors. The positioning photoelectric sensors are kept in a fixed position, and the sensing sheets are fixedly mounted on the ultraviolet lamp box and operate synchronously with the ultraviolet lamp box; or the sensing sheets are fixed in position, and the positioning photoelectric sensors are fixedly mounted on the ultraviolet lamp box and operate synchronously with the ultraviolet lamp box.

[0009] The beneficial effects of this utility model of a UV light box assembly for a gel imaging device are as follows: By setting an automatic in-and-out chamber structure, this utility model can realize the electric control of the UV light box's entry and exit, which has a high degree of automation and is convenient for picking up and putting in samples. Compared with the traditional hand-pulled UV light box, it avoids the additional risk of contamination caused by excessive hand contact with the UV light box when pulling it out.

When an element is referred to as being "connected to" another element, it can be directly connected to or indirectly connected to the other element.

[0021] In the description of this utility model, it should be noted that the terms "center," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1

[0023] See Figures 1-5This utility model discloses a UV light box assembly for a gel imaging instrument, comprising a main body 1, the main body 1 including a light-shielding shell 11, the light-shielding shell 11 being composed of multiple opaque light-shielding plates, the light-shielding plates forming an imaging space, the imaging space containing a UV light box 12 and an automatic in-and-out chamber structure for driving the UV light box 12 to move laterally, the UV light box 12 having a sample illumination area for irradiating the sample, the light-shielding shell 11 having an opening on one side for the UV light box 12 to pass through, an industrial camera 13 being mounted on the upper side of the UV light box 12 within the imaging space, and an illumination assembly 14 cooperating with the industrial camera 13 being mounted next to it. In this embodiment, by setting an automatic inlet and outlet structure on the lower side of the UV lamp box 12, the inlet and outlet of the UV lamp box 12 can be electrically controlled, which is convenient for picking up and putting in samples. Compared with the traditional manual UV lamp box, it avoids the additional risk of contamination caused by excessive hand contact with the UV lamp box when pulling out the UV lamp box. It is equipped with multiple lighting components, which can effectively supplement the light. The light-shielding shell composed of light-shielding plates can effectively avoid external light interference and effectively prevent internal UV light leakage.

[0024] See Figure 3 , Figure 4 and Figure 5 The automatic entry and exit chamber structure includes a first guide rail 15, a synchronous belt 16, pulleys 17, and a drive motor 18. The bottom of the imaging space is provided with the first guide rail 15 for cooperation with the ultraviolet lamp box 12. The ultraviolet lamp box 12 is mounted on the first guide rail 15. A synchronous belt 16, arranged in the same direction as the first guide rail 15, is provided beside it. Pulleys 17 are located at both ends of the synchronous belt 16. A drive motor 18 is connected to each pulley 17 to drive its rotation. The ultraviolet lamp box 12 is fixedly connected to any position on the synchronous belt 16 by a fixing member 21. In this embodiment, the automatic entry and exit chamber is constructed using a belt structure, which is low-cost and stable in operation. The drive motor 18 drives the synchronous belt 16 to rotate, thereby causing the ultraviolet lamp box 12 to move horizontally.

[0025] See Figure 5 A second guide rail 22, arranged in the same direction as the synchronous belt 16, is also provided on the lower side or side of the synchronous belt 16. The fixing member 21 is fixedly connected to the guide rail slider of the second guide rail 22. The second guide rail 22 can improve the stability of the fixing member 21 when it moves, thereby improving the movement stability and accuracy of the ultraviolet lamp box 12.

[0026] Preferably, the drive motor 18 is an encoder motor. Using an encoder motor, when the operation of the ultraviolet lamp box 12 is obstructed, the encoder identifies the obstruction and immediately stops the motor, thus achieving an anti-pinch function. Example 2

[0027] See Figure 6Based on Embodiment 1, the system further includes two positioning photoelectric sensors 23 and a sensing element 24 that cooperates with the positioning photoelectric sensors 23. The positioning photoelectric sensors 23 maintain a fixed position, and the sensing element 24 is fixedly mounted on the ultraviolet lamp box 12 and operates synchronously with the ultraviolet lamp box 12. The two positioning photoelectric sensors 23 are used to locate the extended and retracted positions of the ultraviolet lamp box 12, respectively, which facilitates positioning, improves accuracy, and facilitates cooperation with the automatic loading and unloading mechanism.

[0028] See Figure 6 The sensing element 24 is disposed on the fixing member 21.
