Description

Technical Field

[0001] The utility model relates to the technical field of fixtures for focusing a camera, and particularly relates to a micro camera focusing fixture. Background Technique

[0002] In the prior art, after a conventional camera module is assembled, it still needs to be focused to make the imaging clear, that is, by adjusting the relative position between the lens and the base, the distance between the optical element of the lens and the photosensitive chip is optimized. Usually, there are threads between the lens and the base, and the distance is changed by rotation to play a role in adjustment.

[0003] After adjusting the corresponding focal length, it is also necessary to perform imaging detection on the adjusted camera to make it meet the requirement of clear imaging within the preset focal length. For a conventional camera module, due to its relatively large size, it can be imaged and detected by ordinary hand-held or a simple bracket. However, for the focusing process and imaging detection process of some micro cameras, it is not convenient to implement.

[0004] For example, an endoscope is a photographing device used for visual inspection of inaccessible places such as the human body cavity. It can enter the stomach through the mouth or enter the body through other natural orifices. Using an endoscope, lesions that cannot be shown by X-rays can be seen. Therefore, endoscopes are widely used in modern medical examinations. The camera module used inside the endoscope device is a micro camera, and its size is very small. Conventional focusing operations and imaging detections are not convenient to perform.

[0005] Another example is that in the currently relatively advanced direct vision painless uterine cavity abortion surgery, the camera at the front end of the disposable suction tube used is also a micro camera, which has a small size. And because of its disposable use characteristics, the cost control is relatively more strict. Therefore, usually no complex focusing structure is set.

[0006] Therefore, in the process of focusing operation and imaging detection of a micro camera, it is necessary to design a special fixture to facilitate the focusing operation and forming detection operation of the micro camera module and improve the imaging quality of the micro camera. Content of the Utility Model

[0007] The utility model aims to provide a technical solution that can solve the above problems to overcome the above deficiencies.

[0008] The utility model provides a focusing fixture for a miniature camera, which includes a bottom plate, a slide seat assembly slidably connected to the bottom plate, and a vertical support pillar fixedly connected to the bottom plate.

The slide seat assembly is provided with a placement table for placing and fixing a camera module to facilitate focusing operation. After focusing, the slide seat assembly can move to the lower part of the charting assembly, and the charting assembly provides a detection calibration image for the focused camera module to confirm that the focal length adjustment of the camera module is correct.

[0009] As a further scheme of the utility model: the slide seat assembly is further provided with a cover plate, which is detachably fixedly connected to the placement table and limits the camera module placed on the placement table to make the optical elements of the camera module in a preset position.

[0011] As a further scheme of the utility model: the placement table is respectively provided with a second positioning post and a third positioning post, and the cover plate is respectively provided with a second through hole and a third through hole corresponding to the positions of the second positioning post and the third positioning post. The second through hole and the second positioning post cooperate with each other, and the third through hole and the third positioning post cooperate with each other, so that the cover plate is limited at the preset position of the placement table.

[0012] As a further scheme of the utility model: the placement table is provided with a magnetic part, and the cover plate is made of a material that can be adsorbed by the magnetic part, so that the magnetic part on the placement table can adsorb the cover plate, so that the cover plate is stably covered on the placement table.

[0013] As a further scheme of the utility model: the slide seat assembly is further provided with a first guide rail and a first slider. The first guide rail is fixedly connected to the bottom plate, and the first slider and the first guide rail cooperate with each other to form a linear transmission module. The placement table is fixedly connected to the first slider and thus moves linearly synchronously with the first slider.

[0014] As a further solution of the present utility model: The slide seat assembly is further provided with a second guide rail and a second slider. The second guide rail is fixedly connected to the slide seat assembly. The second slider and the second guide rail cooperate with each other to form a linear drive module. The placement table is fixedly connected to the second slider and thus moves linearly synchronously with the second slider. The slide seat assembly is further provided with a first knob and a first spring. The first knob and the first spring are respectively installed at both ends of the slide seat assembly. The first knob can adjust the positional relationship of the second slider relative to the second guide rail, thereby synchronously adjusting the position of the placement table.

[0015] As a further solution of the present utility model: The bottom plate is further provided with a transverse bracket and a transverse stud that are threadedly connected to each other. The transverse bracket is fixedly connected to the bottom plate.

Detailed implementation manners

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 to 6 , in the embodiment of the present invention, a micro camera focus adjustment jig includes a base plate 10, a slide seat assembly 20 slidably connected to the base plate 10, and a vertical pillar 50 fixedly connected to the base plate 10. The vertical pillar 50 is movably connected to a charting assembly 60. The slide seat assembly 20 is provided with a placement table 21 for placing and fixing the camera module 70 to facilitate focus adjustment operation. After the focus adjustment is completed, the slide seat assembly 20 can be moved to the lower part of the charting assembly 60, so that the charting assembly 60 provides a detection calibration image for the focus-adjusted camera module 70, thereby ensuring that the focus of the camera module 70 is adjusted correctly. The slide seat assembly 20 is further provided with a cover plate 40, and the cover plate 40 is detachably fixed to the placement table 21 to limit the camera module 70 on the placement table 21, so that the optical element 71 of the camera module 70 is in a preset position.

[0035] Specifically, due to the use environment of the micro camera, it is necessary to maintain a very small size, which also brings difficulties in production. Especially when adjusting its focal length, due to its too small size, it is not convenient to operate. Therefore, corresponding jigs need to be set to fix it. At the same time, it is also necessary to perform focal length imaging detection on the focus-adjusted micro camera module 70. Therefore, preferably, a jig is set to achieve both focus adjustment operation and imaging detection.

[0036] Secondly, a slider assembly 20 that slides on the first guide rail 31 can be set up, and the placement table 21 installed thereon is used to fix the micro camera module 70. Then, a focusing operation is performed at the focusing station away from the vertical support 50. After the focusing is completed, the slider assembly 20 is pushed to the position below the image-taking assembly 60 of the vertical support 50 by using the linear motion module of the first guide rail 31 and the first slider 32 to perform imaging detection on the focused camera module 70. The focusing operation can be that an operator uses relevant focusing tools to focus the optical element 71, or it can be that an automated focusing device specifically for micro cameras is used for the focusing operation.

[0037] Thirdly, the image-taking assembly 60 mainly provides a calibrated image in a standard existing product. The flexible circuit board 73 of the camera module 70 can be connected to a corresponding control device or electronic device. After taking a picture of the calibrated image, a corresponding captured image is output, so as to ensure whether the captured image is clear, and further confirm whether the adjustment of the focal length is correct. It can be understood that the image-taking assembly 60 can be an existing product, which can be directly purchased and installed on the vertical slider 53 for corresponding use. In order to make the pattern of the calibrated image itself clearer, a corresponding lighting group 61 can be set on the image-taking assembly 60 to illuminate the calibrated image, which is convenient for the camera to take pictures for detection.

[0038] As Figures 4 to 6 shown, preferably, the cover plate 40 is provided with a focusing limit hole 41 corresponding to the position of the optical element 71 of the camera module 70, so that the optical element 71 of the camera can pass through the focusing limit hole 41, and the adjusting ring of the optical element 71 protrudes from the cover plate 40, so as to facilitate the rotation of the adjusting ring and further adjust the focal length; the placement table 21 is provided with a first positioning post 22 corresponding to the position of the head through hole 72 of the camera module 70, and the first positioning post 22 is used to receive the head through hole 72 of the camera module 70, so that the head of the camera module 70 can be sleeved on the first positioning post 22; the placement table 21 is provided with a limiting groove 23 corresponding to the position of the flexible circuit board 73 of the camera module 70, and the limiting groove 23 is used to accommodate the flexible circuit board 73 of the camera module 70.

[0039] Specifically, due to the small size of the micro camera itself, and the even smaller size of its optical element 71, similarly, the size of its focusing ring is also smaller. Therefore, in order to facilitate the corresponding rotation of the focusing ring for focusing, a corresponding focusing limit hole 41 can be provided on the cover plate 40, so that the optical element 71 is exactly located at the position of the focusing limit hole 41, and the focusing ring can even pass through the focusing limit hole 41 and protrude a certain part to make it easy to be operated. Therefore, the shape of the focusing limit hole 41 needs to be set accordingly according to the shape of the optical element 71 part of the micro camera. In addition, a first through hole 42 is provided on the cover plate 40 corresponding to the position of the first positioning post 22, so that the first positioning post 22 can penetrate into the first through hole 42 to avoid interference with the cover plate 40.

[0040] As Figures 5 to 6 shown, preferably, a second positioning post 24 and a third positioning post 25 are respectively provided at the diagonal positions of the placement table 21, and second through holes 43 and third through holes 44 are respectively provided on the cover plate 40 corresponding to the positions of the second positioning post 24 and the third positioning post 25. The second through hole 43 and the second positioning post 24 cooperate with each other, and the third through hole 44 and the third positioning post 25 cooperate with each other, so that the cover plate 40 is limited to a preset position on the placement table 21. A magnetic member 26 is provided on the placement table 21, and the cover plate 40 is made of a material that can be adsorbed by the magnetic member 26, so that the magnetic member 26 on the placement table 21 can adsorb the cover plate 40, so that the cover plate 40 is stably covered on the placement table 21.

[0041] Specifically, in order to fix the cover plate 40 and prevent it from shifting, corresponding positioning posts can be provided at the diagonal positions of the placement table 21, and at the same time, corresponding through holes can be provided on the cover plate 40, so that it can be positioned by the cooperation of the positioning posts and the through holes to ensure that the cover plate 40 can be covered at the preset position. In addition, in order to prevent the cover plate 40 from shifting during operation, a corresponding magnetic member 26, such as a magnet element, can also be provided on the placement table 21, and the cover plate 40 can be made of iron sheet, so that the magnet element can adsorb the iron sheet. It can be understood that the magnetic force of the magnet element should not be too large, and it should be set to be able to adsorb the cover plate 40 and can also remove the cover plate 40 again after applying a certain pulling force.

[0042] As Figure 2 and Figure 3As shown, preferably, the carriage assembly 20 is further provided with a first guide rail 31 and a first slider 32. The first guide rail 31 is fixedly connected to the bottom plate 10, and the first slider 32 is engaged with the first guide rail 31 to form a linear drive module. The placement table 21 is fixedly connected to the first slider 32 and thus moves linearly synchronously with the first slider 32. The carriage assembly 20 is further provided with a second guide rail 33 and a second slider 34. The second guide rail 33 is fixedly connected to the carriage assembly 20, and the second slider 34 is engaged with the second guide rail 33 to form a linear drive module. The placement table 21 is fixedly connected to the second slider 34 and thus moves linearly synchronously with the second slider 34. The carriage assembly 20 is further provided with a first knob 35 and a first spring 36. The first knob 35 and the first spring 36 are respectively installed at both ends of the carriage assembly 20. The first knob 35 can adjust the positional relationship of the second slider 34 relative to the second guide rail 33, thereby synchronously adjusting the positional relationship of the placement table 21.

[0043] Specifically, in order to enable the carriage assembly 20 to slide between the focusing station and the imaging detection station, the first guide rail 31 and the first slider 32 can be provided to cooperate to achieve linear motion. Similarly, in order to adjust the position of the placement table 21, the second guide rail 33, the second slider 34, the first knob 35 and the first spring 36 can also be provided, so that the position of the placement table 21 relative to the second slider 34 can be adjusted, enabling the optical element 71 of the camera module 70 to be aligned with the calibration image of the chart assembly 60 and making the imaging detection more accurate.

[0044] As Figures 1 to 3 shown, preferably, the bottom plate 10 is further provided with a transverse bracket 11 and a transverse stud 12 that are threadedly connected to each other. The transverse bracket 11 is fixedly connected to the bottom plate 10, and the transverse stud 12 is rotatably connected to the transverse bracket 11 and can abut against the carriage assembly 20 to ensure the positional relationship of the carriage assembly 20 in the transverse direction.

[0045] Specifically, during the process of the carriage assembly 20 moving towards the vertical pillar 50, that is, when the carriage assembly 20 moves to the imaging detection station below the chart assembly 60, in order to ensure its accurate position, the transverse bracket 11 and the transverse stud 12 can also be provided. By using the abutment of the transverse stud 12 against the carriage assembly 20, its position relative to the chart assembly 60 is in a preset position. Additionally, a magnetic member 26 can be provided at one end of the transverse stud 12 that abuts against the carriage assembly 20, or a magnetic member 26 can be provided at the position where the carriage assembly 20 contacts the transverse stud 12. The magnetic member 26 can adsorb the carriage assembly 20 at the position where the transverse stud 12 abuts. Similarly, the magnetic force of the magnetic member 26 needs to be relatively appropriate to ensure that the carriage assembly 20 can still be pulled out again.

[0046] As Figures 1 to 3As shown, preferably, the vertical pillar 50 is further provided with a vertical lead screw 51, a second knob 52 and a vertical slider 53. The vertical lead screw 51 is rotatably connected to the vertical pillar 50. The second knob 52 is fixedly connected to the vertical lead screw 51. The vertical slider 53 is sleeved on the vertical lead screw 51 and forms a linear drive module with the vertical lead screw 51, so that rotating the second knob 52 can adjust the positional relationship of the vertical slider 53 relative to the vertical lead screw 51. The chart alignment component 60 is fixedly connected to the vertical slider 53 and moves linearly synchronously with the vertical slider 53.

[0047] Specifically, in order to adjust the distance relationship between the chart alignment component 60 and the camera module 70, the height of the chart alignment component 60 can also be adjusted by the vertical lead screw 51 and the second knob 52 to make the imaging detection of the camera module 70 more accurate. In addition, the vertical pillar 50 is further provided with a guiding rod 54. The guiding rod 54 is fixedly connected to the vertical pillar 50, so that the vertical slider 53 is sleeved on the guiding rod 54 and can slide along the guiding rod 54. Thus, when the vertical lead screw 51 adjusts the vertical distance of the vertical slider 53, it can prevent the vertical slider 53 from making a circular motion around the vertical lead screw 51.

[0048] As Figure 2 and Figure 3 As shown, preferably, the vertical pillar 50 is further provided with a locking knob 55 and a locking screw 56 which are fixedly connected to each other. The locking screw 56 is rotatably connected to the vertical pillar 50. One end of it is fixedly connected to the locking knob 55, and the other end abuts against the vertical slider 53, thereby locking the position of the vertical slider 53.

[0049] Specifically, since the chart alignment component 60 is installed on the vertical slider 53, its stability needs to be maintained. Therefore, the vertical slider 53 can be locked by setting the locking screw 56 and the locking knob 55 to ensure its stability.

[0050] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present invention.
