[0021] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] It should be noted that if any directional indication, such as up, down, left, right, front, back, etc., is involved in the embodiments of this utility model, such directional indication is only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indication will also change accordingly. Furthermore, if any description involving "first," "second," "S1," "S2," "step one," "step two," etc., is involved in the embodiments of this utility model, such description is only for descriptive purposes and should not be construed as indicating or implying their relative importance, or implicitly indicating the number of technical features indicated or the execution order of the method. Those skilled in the art will understand that anything that does not violate the essential points of the utility model within the scope of its inventive concept should be included within the protection scope of this utility model.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-4 As shown, this utility model provides a vibration damping imaging device, including a passive vibration damping component, an active vibration damping component, and an imaging component; the passive vibration damping component is used to support and isolate the active vibration damping component and to isolate low-frequency vibration interference; the active vibration damping component is located above the passive vibration damping component and is used to isolate high-frequency vibration interference and support the imaging component; the imaging component is located on the passive vibration damping component and is used to acquire image information.

[0025] For example, when high-end imaging is required, the active damping component is first installed on the ground, then the passive damping component is installed on top of the active damping component, then the imaging component is installed on the passive damping component, and finally the object to be imaged is transported to the imaging component by an external conveyor device, and then operation can begin.

[0026] During operation, the imaging component is susceptible to vibration interference from both low-frequency and high-frequency frequencies. Therefore, this invention employs a longitudinal arrangement of passive and active vibration damping components, with zones for absorbing and isolating both low-frequency and high-frequency vibrations. Low-frequency vibrations primarily originate from external transmission devices. These devices often perform mechanical actions, generating significant amounts of low-frequency vibrations that are transmitted to the imaging component via the ground. This invention uses passive vibration damping components in contact with the ground to absorb these vibrations and prevent further transmission that could affect the imaging component. High-frequency vibrations, with a different frequency than low-frequency vibrations, continue to be transmitted after passing through the passive damping components. At this point, the active vibration damping components, positioned above the active damping components, absorb and isolate the high-frequency vibrations transmitted from the passive damping components, preventing them from affecting the imaging component.

[0027] The utility model discloses a key lies at: through longitudinal setting passive damping component and initiative damping component, realize the partition, the classified insulation absorption of low frequency vibration and high frequency vibration, provide a stable imaging environment for imaging assembly, improve the imaging effect of imaging assembly, and the external transmission device mentioned in the embodiment is prior art, and the external transmission device of any prior art can be selected to transport the imaging object in the embodiment, and it does not belong to the necessary technical features of the utility model operation, so here is not superfluous.

[0028] As Figure 4 The passive damping component is open rack bottom plate 1, and the open rack bottom plate 1 is provided with mounting through hole 101 for installing other devices.

[0029] When the external conveying device is needed to transport the imaging object, the external conveying device is installed into the mounting through hole 101, which can better isolate the vibration generated by the external conveying device compared with directly installing the external conveying device on the open rack bottom plate 1, and at the same time, the mode can shorten the transportation distance of the external conveying device for transporting the imaging object, avoiding the damage of the imaging object caused by the fluctuation of the external conveying device in the transportation process.

[0030] It is worth noting that in this embodiment, only the use mode of the mounting through hole 101 is limited, but the specific number, shape, size and position are not limited, that is, the specific number, shape, size and position of the mounting through hole 101 can be designed by the person skilled in the art according to the actual situation.

[0031] The number and position of the mounting through hole 101 will greatly affect the imaging efficiency of the imaging assembly, and therefore the utility model provides a preferred embodiment.

[0032] Preferably, as Figure 4 The mounting through hole 101 is two, and is symmetrically distributed on both sides of the imaging assembly.

[0033] The two external conveying devices are installed into the mounting through holes 101 on both sides of the imaging assembly respectively, at this time, one external conveying device is only responsible for placing the imaging object on the imaging assembly, and after the imaging assembly completes imaging, the other external conveying device removes the imaged object from the imaging assembly, so as to realize the rapid imaging of the imaging assembly and improve the imaging efficiency of the imaging assembly.

[0034] More preferably, as Figure 1 The passive damping component further includes a plurality of damping foot cups 2 located at the bottom of the open rack bottom plate 1.

[0035] The low-frequency vibration generated by the external conveying mechanism is mainly transmitted through the ground to affect the imaging assembly, and therefore the utility model discloses a plurality of shock-absorbing foot cups 2 are arranged at the bottom of the open rack bottom plate 1 to absorb the low-frequency vibration generated by the external conveying device.

[0036] It is worth noting that in the embodiment, the function and the approximate installation position of the shock-absorbing foot cup 2 are limited, but the specific layout, size, number and style of the shock-absorbing foot cup 2 are not limited, that is, the specific layout, size, number and style of the shock-absorbing foot cup 2 can be arbitrarily set by the person skilled in the art according to the actual situation.

[0037] Preferably, as shown in the figure, Figures 1-3 The active shock-absorbing assembly comprises a bracket bottom plate 3, a mounting bracket 4 and an air floating platform 5; the bracket bottom plate 3 is located at the middle position of the upper end of the open rack bottom plate 1 and is used for connecting the open rack bottom plate 1; the mounting bracket 4 is located above the bracket bottom plate 3 and is used for mounting the imaging assembly; and the air floating platform 5 is located between the bracket bottom plate 3 and the mounting bracket 4 and is used for absorbing the vibration transmitted from the bracket bottom plate 3 to the mounting bracket 4.

[0038] Firstly, the bracket bottom plate 3 is mounted on the open rack bottom plate 1, then the air floating platform 5 is mounted on the top of the bracket bottom plate 3, and finally the mounting bracket 4 is mounted above the air floating platform 5, and then the use can be started. During use, since the open rack bottom plate 1 at the bottom has absorbed the low-frequency vibration, the vibration transmitted along the open rack bottom plate 1 is mainly high-frequency vibration, and when the high-frequency vibration is transmitted upward, it will first contact the air floating platform 5, and the air floating platform 5 mainly uses the gas film to support the object, so that the high-frequency vibration will be difficult to transmit after contacting the air floating platform 5, thereby achieving the isolation and absorption of the high-frequency vibration.

[0039] Preferably, as shown in the figure, Figures 2-3 The connection between the bracket bottom plate 3 and the mounting bracket 4 is a plane.

[0040] Since the bracket bottom plate 3 and the mounting bracket 4 need to be supported by the air floating platform 5, and a stable plane is provided for the imaging assembly to work, the utility model discloses that the connection between the bracket bottom plate 3 and the mounting bracket 4 is a plane, so that a sufficient number of air floating platforms 5 can be installed to ensure that the imaging assembly can stably operate.

[0041] It is worth noting that in the embodiment, the state of the connection between the bracket bottom plate 3 and the mounting bracket 4 is limited, but the shape, size and thickness of the plane are not set, that is, the shape, size and thickness of the plane of the connection between the bracket bottom plate 3 and the mounting bracket 4 can be arbitrarily set by the person skilled in the art.

[0042] The number and installation position of the air floating platforms 5 will affect the stability of the imaging assembly and the imaging effect, and therefore the utility model provides an optimal embodiment.

[0043] Preferably, as shown in the figure, Figure 3 The number of the air floating platforms 5 is four, which are evenly distributed at the four corner positions of the connecting surface of the support bottom plate 3 and the mounting support 4.

[0044] The four air floating platforms 5 are evenly distributed at the four corner positions of the connecting surface of the support bottom plate 3 and the mounting support 4, which can effectively ensure the stability of the mounting support 4 and effectively absorb the high-frequency vibration transmitted from the support bottom plate 3 to the top, thereby ensuring the imaging effect of the imaging assembly.

[0045] The support bottom plate 3 mainly functions to increase the height of the imaging assembly, but in order to avoid excessive increase of the overall mass of the equipment, a column structure is adopted, but the mass of the imaging assembly is relatively large and the height is relatively high, and therefore the utility model provides an optimal embodiment to ensure the stability of the support bottom plate 3.

[0046] Preferably, as shown in the figure, Figure 3 The support bottom plate 3 further comprises a longitudinal stabilizer 301 for enhancing the longitudinal stability of the support bottom plate 3.

[0047] The longitudinal stabilizer 301 is arranged on the support bottom plate 3, which can effectively improve the longitudinal stability of the support bottom plate 3 and prevent the support bottom plate 3 from tilting to affect the imaging effect of the imaging assembly.

[0048] It is worth noting that in this embodiment, only the function of the longitudinal stabilizer 301 is limited, but the specific size, shape, thickness and installation position of the longitudinal stabilizer 301 are not limited, that is, the specific size, shape, thickness and installation position of the longitudinal stabilizer 301 can be arbitrarily set by the person skilled in the art according to the actual situation.

[0049] Specifically, as shown in the figure, Figure 3 The longitudinal stabilizer 301 is located at the periphery of the support bottom plate 3.

[0050] The longitudinal stabilizer 301 is arranged at the periphery of the support bottom plate 3, which can effectively ensure the spaciousness of the bottom space of the support bottom plate 3 and avoid the transmission of low-frequency vibration to the top to a greater extent.

[0051] Specifically, as shown in the figure, Figure 3 The longitudinal stabilizer 301 is a triangular reinforcing rib.

[0052] The triangular reinforcing rib has high reinforcing effect and small occupied area, and can maintain low mass increase and contact area increase under the premise of providing stable support force for the support bottom plate 3, thereby preventing the transmission of vibration to the top.

[0053] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several deformations and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
