Description

Technical Field

[0001] The present invention relates to the technical field of endoscope imaging modules, and in particular to a front end structure of an endoscope imaging module. Background Art

[0002] An endoscope is a detection instrument that integrates traditional optics, ergonomics, precision mechanics, modern electronics, mathematics, and software. It has image sensors, optical lenses, light sources, mechanical devices, etc. The endoscope imaging module is the core functional component of the endoscope, responsible for collecting, processing, and transmitting real-time images of the human body's internal cavities.

[0003] In existing endoscope imaging modules, the LED is usually set at the bottom of the camera. Therefore, during use, light leakage may occur, resulting in insufficient light source for the camera and affecting the endoscope imaging effect. Summary of the Invention

[0004] The object of the present invention is to provide a front-end structure of an endoscope imaging module to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a front-end structure of an endoscope imaging module, comprising a PC shell and a microstructure array lens, a limiting groove being provided inside the PC shell, a camera module being housed inside the limiting groove, and LED modules being provided on both sides of the camera module, the microstructure array lens being provided on one side of the LED module, and a wiring assembly being provided on the other side of the LED module, the wiring assembly comprising a fixing plate, a pin contact, a guide groove, a sliding column, a splint, a rubber pad, a damping shaft, a cam and a shift block, a pin contact being provided on one side of the fixing plate, and a guide groove being provided on the other side of the fixing plate, a sliding column being connected to the upper and lower ends of the fixing plate, and the end of the sliding column being slidably connected to the splint, and a rubber pad being fixed to one side of the splint, a damping shaft being provided on the other side of the LED module, and the outer side of the damping shaft being rotatably connected to the cam, and a shift block being fixed to one side of the cam.

[0006] Furthermore, limiting portions are provided on both sides of one end of the limiting groove, and the limiting portions match the LED module.

[0007] Furthermore, inclined portions are symmetrically provided on both sides of the other end of the limiting groove, and the inclination angle of the inclined portions is 20 degrees.

[0008] Furthermore, the fixing plate is L-shaped, and the fixing plate is fixedly connected to the LED module.

[0009] Furthermore, the guide grooves correspond to the pin contacts one by one, and the pin contacts are fixedly connected to the LED module.

[0010] Furthermore, a plug-in assembly is provided at one end of the camera module, and the plug-in assembly includes a socket and a plug. A socket is placed at one end of the camera module, and a plug is plugged into one side of the socket.

[0011] Furthermore, the plug assembly also includes a fixed block, an elastic plate and a stop block. The fixed blocks are fixed on both sides of the socket, one end of the fixed block is connected to the elastic plate, and the end of the elastic plate is provided with a stop block.

[0012] Furthermore, the stopper is trapezoidal and fits the plug.

[0013] Furthermore, the operation method is as follows: insert the plug into the socket to quickly connect the cable and the camera module. During the plugging process, the plug will squeeze the inclined part of the block, causing the elastic plate to bend and automatically avoid. After plugging, the elastic plate will reset, so that the block fits the end of the plug, quickly limiting the position between the socket and the plug. The dial block is turned to drive the cam to rotate so that the concave part of the cam is located at the clamping plate. The sliding clamping plate inserts the wire into the guide groove, and the guide groove is used to preliminarily limit the wire. After insertion, it is only necessary to dial the dial block in the opposite direction again so that the convex part of the cam squeezes the clamping plate so that it slides along the sliding column, clamping the wire on the pin contact piece, quickly wiring the LED module, and through the rubber pad and damping shaft, the camera module and LED module are placed in the limit groove. The limit part limits the position of the LED module. During the glue injection process, the inclined part can reduce the remaining space inside the PC shell. By arranging the LED module at the front end of the camera module, the LED modules are symmetrically distributed on both sides of the camera module.

[0014] The present invention provides an endoscope imaging module front-end structure, which has the following beneficial effects: 1. The present invention arranges the LED module at the front end of the camera module, thereby increasing the light source when providing illumination. At the same time, the LED modules are symmetrically distributed on both sides of the camera module, further increasing the illumination range. In addition, the micro-lens array structure of the microstructure array lens and the micro-scale structural design are used to precisely control the propagation direction and energy distribution of light, ultimately achieving uniform light field output, which is conducive to improving the uniformity of illumination and further enhancing the shooting effect of the endoscope imaging module. 2. The present invention provides a wiring assembly. When the LED module needs to be wired, the shift block is first moved to drive the cam to rotate so that the concave part of the cam is located at the clamping plate. At this time, the sliding clamping plate facilitates the insertion of the wire into the guide groove. The guide groove can be used to initially limit the wire. After insertion, it is only necessary to shift the shift block in the opposite direction again to make the convex part of the cam squeeze the clamping plate, causing it to slide along the sliding column, thereby clamping the wire on the pin contact piece. The LED module can be quickly wired, and the stability of positioning is increased by the rubber pad and the damping shaft. Compared with the existing method that requires welding tooling to connect the wire to the LED module, the present application does not require the use of other tools, which is conducive to improving the convenience during maintenance and inspection.

[0015] 3. The present invention can reduce the remaining space inside the PC shell by setting the inclined portion. Therefore, when the glue is used to fill the inside of the limit groove to ensure the stability and sealing of the component, compared with the existing front-end structure of the endoscopic imaging module, the present application can reduce the amount of glue, so it is less likely to generate bubbles, avoiding a large number of bubbles affecting the stability of the component, thereby improving the shooting effect of the endoscopic imaging module.

[0018] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0019] like Figures 1 to 4As shown, a front-end structure of an endoscope imaging module includes a PC shell 1 and a microstructure array lens 7. A limiting groove 2 is provided inside the PC shell 1. Inclined portions 4 are symmetrically provided on both sides of the other end of the limiting groove 2, and the inclination angle of the inclined portion 4 is 20 degrees. The inclined portion 4 can reduce the remaining space inside the PC shell 1. Therefore, when the limiting groove 2 is subsequently filled with glue to ensure the stability and sealing of the component, it is less likely to produce bubbles due to the reduction in the amount of glue, which avoids more bubbles affecting the stability of the component and is beneficial to improving the shooting effect of the endoscope imaging module. A camera module 5 is arranged inside the limiting groove 2, and LED modules 6 are provided on both sides of the camera module 5. By arranging the LED module 6 at the front end of the camera module 5, When providing lighting, the light source is increased, and the LED modules 6 are symmetrically distributed on both sides of the camera module 5, further improving the illumination range. A limiting portion 3 is set on both sides of one end of the limiting groove 2, and the limiting portion 3 matches the LED module 6. The limiting portion 3 can limit the LED module 6. The microstructure array lens 7 is placed on one side of the LED module 6, and a wiring assembly 8 is set on the other side of the LED module 6. Through the microscopic scale structural design of the microstructure array lens 7, the propagation direction and energy distribution of the light are precisely controlled, and finally a uniform light field output is achieved, which is conducive to improving the uniformity of light illumination and further improving the shooting effect of the endoscope imaging module. The wiring assembly 8 includes a fixing plate 801, a pin contact piece 802, a guide groove 803, Slide column 804, splint 805, rubber pad 806, damping shaft 807, cam 808 and shift block 809, one side of the fixed plate 801 is provided with a pin contact piece 802, and the other side of the fixed plate 801 is provided with a guide groove 803. Since the opening size of the guide groove 803 matches the wire, the wire can be initially limited by the guide groove 803. The fixed plate 801 is L-shaped, and the fixed plate 801 is fixedly connected to the LED module 6. The fixed plate 801 can limit one end of the wire. The guide groove 803 corresponds to the pin contact piece 802 one by one, and the pin contact piece 802 is fixedly connected to the LED module 6. When the wire contacts the pin contact piece 802, it can be electrically connected to the LED module 6. The upper and lower ends of the fixed plate 801 are connected with slides. 805, and the end of the sliding column 804 is slidably connected to the clamping plate 805, and a rubber pad 806 is fixed to one side of the clamping plate 805. A damping shaft 807 is placed on the other side of the LED module 6, and the outer side of the damping shaft 807 is rotatably connected to the cam 808, and a dial block 809 is fixed to one side of the cam 808. When it is necessary to connect the LED module 6, the dial block 809 is first dialed to drive the cam 808 to rotate, so that the concave part of the cam 808 is located at the clamping plate 805. At this time, the sliding clamping plate 805 is convenient for inserting the wire into the guide groove 803. After inserting the wire, it is only necessary to dial the dial block 809 in the opposite direction to make the convex part of the cam 808 squeeze the clamping plate 805, so that it slides along the sliding column 804, thereby clamping the wire on the pin contact 802.The LED module 6 can be quickly wired, and the rubber pad 806 and the damping shaft 807 can increase the stability of the positioning.

[0020] like Figure 2 and Figure 5 As shown, one end of the camera module 5 is provided with a plug assembly 9, and the plug assembly 9 includes a socket 901 and a plug 902. The socket 901 is placed at one end of the camera module 5, and the plug 902 is plugged into one side of the socket 901. By inserting the plug 902 into the socket 901, the cable and the camera module 5 can be quickly connected. The plug assembly 9 also includes a fixed block 903, an elastic plate 904 and a stopper 905. Fixed blocks 903 are fixed on both sides of the socket 901, and one end of the fixed block 903 is connected to the elastic plate 904, and a stopper 905 is provided at the end of the elastic plate 904. The stopper 905 It is trapezoidal, and the stopper 905 fits with the plug 902. During the plugging process, the plug 902 will squeeze the inclined portion 4 of the stopper 905, causing the elastic plate 904 to bend and automatically avoid. After plugging, the elastic plate 904 resets, which will make the stopper 905 fit the end of the plug 902, quickly limiting the position between the socket 901 and the plug 902 to prevent them from loosening. When disassembly is required, it is only necessary to push the stopper 905 hard to separate the plug 902, which can quickly release the restriction between the socket 901 and the plug 902, making disassembly very convenient.

[0021] In summary, the front-end structure of the endoscope imaging module is used first according to Figures 1 to 5803, and after insertion, the convex part of the cam 808 can squeeze the splint 805, so that it can slide along the slide post 804, thereby clamping the wire in the guide groove 803. On the foot contact piece 802, the LED module 6 can be quickly wired, and the rubber pad 806 and the damping shaft 807 can be used to increase the stability during positioning. Then, the camera module 5 and the LED module 6 are placed in the limit groove 2, and the limit part 3 can limit the position of the LED module 6. Then, during the glue injection process, the remaining space inside the PC shell 1 can be reduced by the inclined part 4. Therefore, when the glue is subsequently used to fill the inside of the limit groove 2 to ensure the stability and sealing of the component, at the same time, since the amount of glue is reduced, it is less likely to produce bubbles. Finally, during use, since the LED module 6 is set at the front end of the camera module 5, the light source is increased when providing lighting. At the same time, the LED modules 6 are symmetrically distributed on both sides of the camera module 5, further improving the illumination range, and the microlens array structure of the microstructure array lens 7 further improves the shooting effect of the endoscopic imaging module.
