Description

Endoscope capsule lamp panel cover and endoscope capsule

Technical Field

The utility model relates to a medical appliance, in particular to a component of an endoscope capsule and an assembly method of the capsule.

Background

The wireless capsule endoscope is widely applied to the aspect of examining digestive tract diseases of patients, and the structure of the wireless capsule endoscope is that an image acquisition module, a signal processing module, a battery, a radio frequency module and an antenna are integrated into a capsule core through a bracket and then are installed in a capsule shell, for example, the wireless capsule endoscope disclosed in CN 208659309U. As a simple assembling mode, electronic components such as the image acquisition module, the signal processing module and the radio frequency module are arranged on at least two PCBs, and the PCBs are connected through flexible parts such as FPC. The battery is arranged between the two PCBs through the spring and provides power for the PCBs.

However, in the assembly process of the existing capsule core, the PCB tends to bounce under the action of the FPC belt, so the assembly is difficult, and the FPC belt is easy to be extruded or twisted, so that the capsule core has poor contact or poor phenomena such as short circuit, disconnection and the like. To prevent the PCB from bouncing, the housing and the optical front cover are pressed against the PCB during capsule assembly. However, the dimensional accuracy of the PCB is usually plus or minus 0.1mm, so that the assembly error is large, and even the PCB is difficult to press, which directly results in low yield of products and low production efficiency.

Those skilled in the art have therefore endeavored to develop a structure and method that allows a capsule endoscope front cover and rear housing to be assembled with high precision.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned drawbacks of the prior art, the present invention provides a structure and a method for assembling a front cover and a rear shell of a capsule endoscope with high precision.

In order to achieve the purpose, the utility model provides an endoscope capsule lamp panel cover, which comprises a cover body; the middle part of the cover body is provided with a camera hole; the edge of the end part of the cover body is provided with a convex pressing position.

In order to prevent the inconvenience of assembling the PCB due to the self-memory resilience of the FPC (soft) when the optical front cover is not buckled on the shell, the end part of the cover body is provided with a positioning column.

Preferably, four positioning columns are uniformly distributed at the end part of the cover body.

In order to enable the appearance of the capsule core to be more integrated and not expose any other parts, the top of the cover body is provided with a clearance hole.

In order to prevent the optical adverse phenomena of lens imaging blurring, light reflection and the like, the inner side of the clearance hole of the cover body is provided with a shading ring.

The utility model also provides an endoscope capsule, which comprises a shell and an optical front cover; an inner core is arranged in the shell; the joint of the shell and the optical front cover is provided with the endoscope capsule lamp panel cover.

Preferably, the optical front cover is arranged at both ends of the shell; the two ends of the inner core are axially fixed through the pressing positions of the endoscope capsule lamp panel covers which are abutted against each other.

The utility model has the advantages that: the utility model can prevent the capsule shell hood from being difficult to assemble after the PCB board bounces, improve the production efficiency, and is convenient to disassemble and maintain; and bad contact or short circuit, disconnection and other bad phenomena caused by FPC extrusion or distortion are reduced; the integrity of the whole capsule is improved, and the whole capsule is more attractive; the PCB is simple to assemble, not easy to warp and high in yield; and the lens is clear in imaging and is not reflective.

Detailed Description

The invention will be further explained with reference to the following figures and examples:

an endoscopic capsule assembly method comprising the steps of:

1) providing a capsule shell, a capsule core and an optical front cover;

2) loading the capsule core into the shell;

3) a cover body is arranged at the end part of the capsule inner core; the end of the cover body abuts against the capsule inner core and has a pressing position with a radial size extending to the connecting part of the capsule shell;

4) the capsule housing is mated with the optical front cover.

As shown in fig. 1, the above-described assembling method results in an endoscope capsule including a housing 100, both ends of the housing 100 being provided with optical front covers 200, and an inner core 300 being provided in the housing 100. An endoscope capsule light board cover 400 is provided at the junction of the housing 100 and the optical front cover 200. The inner core 300 is axially fixed at both ends by the pressed position of the abutting endoscope capsule light board cover 400.

Specifically, as shown in fig. 2 to 5, the endoscope capsule lamp panel cover includes a cover body 1, a camera hole 1a is provided in the middle of the cover body 1, and a convex pressing position 4 is provided at the edge of the end of the cover body 1. Because the lamp plate cover part adopts the mould preparation shaping, the precision of its suppression position can reach plus-minus 0.01mm, far exceeds the precision of PCB, alright like this improve production efficiency again can reduce the defective rate in the production process.

The tip equipartition of the cover body 1 has four reference columns 5, and during the assembly, reference column 5 card is gone into corresponding PCB board, makes the PCB board of capsule kernel no longer upwards bounce to realize Z to location and rotational positioning. The top of the cover body 1 is provided with clearance holes 2, and clearance holes 2 are set for according to the quantity and the size of the light emitting source, so except that the light emitting source and the lens are necessarily exposed, other electronic devices are all covered by the lamp panel cover, thereby improving the integrity of the capsule and being more beautiful.

The cover body 1 is provided with the shading ring 3 at the inner side of the clearance hole 2, so that the light of the luminous source can not directly irradiate the lens, thereby preventing the optical bad phenomena of lens imaging blurring, light reflection and the like.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
