Description

Technical Field

[0001] The present application relates to the technical field of lens adjustment, and in particular to a camera module adjustment jig and a camera module adjustment device. Background Art

[0002] During lens testing, the lens focal length must be adjusted to achieve a clearer image. Currently, the lens is typically clamped in a jig before focusing and testing. However, this jig obstructs the lens, making it impossible to monitor the current focus status, reducing the efficiency of lens focus testing. Summary of the Invention

[0003] Based on this, it is necessary to provide a camera module adjustment jig and a camera module adjustment device to address the problem that the current jig cannot check the current focusing status in time after clamping the lens, resulting in reduced lens focusing test efficiency.

[0004] According to one aspect of the present application, a camera module adjustment jig is provided, wherein the camera module includes a photosensitive device, a lens barrel and a lens, the photosensitive device is arranged opposite to the lens, and the lens is installed in the lens barrel, and the camera module adjustment jig includes: a supporting seat, which is used to support the camera module; a rotating table, which is provided on the supporting seat and can rotate relative to the supporting seat around a preset axis, and the rotating table is provided with a receiving groove that passes through the rotating table, and the receiving groove is configured to accommodate the camera module; and a clamping mechanism, which is provided on the supporting seat and is configured to clamp the lens barrel so that the lens and the photosensitive device can approach or move away from each other as the rotating table rotates relative to the supporting seat.

[0005] The camera module adjustment jig provided in an embodiment of the present application comprises a rotating platform and a clamping mechanism disposed on a support base, and a receiving slot disposed on the rotating platform, so that the camera module on the support base can be accommodated in the receiving slot. Furthermore, the clamping mechanism is used to clamp the lens barrel, so that when the rotating platform rotates relative to the support base, the lens within the lens barrel can move closer to or further away from the photosensitive device as the lens barrel rotates, thereby achieving focal length adjustment. Based on this, by electrically connecting the camera module's drive circuit to a display device, the focus adjustment status can be monitored in real time based on the clarity of the image output by the display device.

[0006] In some embodiments, the lens barrel is provided with a focusing groove; the clamping mechanism includes a snap joint, an end of the snap joint facing away from the support base being snap-fitted with the focusing groove. When the snap joint of the clamping mechanism is snap-fitted with the focusing groove on the lens barrel, the clamping mechanism is provided on the support base, thereby securing the lens barrel relative to the support base, while the lens base can be secured to the rotating stage. Consequently, when the rotating stage rotates relative to the support base, the lens barrel rotates relative to the lens base, thereby achieving focal length adjustment.

[0007] In some embodiments, the lens barrel is provided with a plurality of focusing grooves spaced along its circumference; the clamping mechanism has a plurality of the clamping joints, and the plurality of the clamping joints are provided in a one-to-one correspondence with the plurality of the focusing grooves. In this way, the cooperation between the plurality of the clamping joints and the plurality of the focusing grooves can make the clamping mechanism clamp the lens barrel more firmly, thereby making the lens barrel better stable during the focusing process.

[0008] In some embodiments, the support base is provided with a mounting slot; the clamping mechanism includes a support column and a clip, one end of the support column being mounted in the mounting slot and the other end extending away from the support base; the clip is connected to the support column, and the length of the clip extends perpendicular to the extension direction of the support column to form the clip joint. Based on this, when the camera module is supported on the support base and accommodated in the accommodating slot of the rotating stage, the clip connected to the support column is pressed down from above the camera module, so that the clip engages with the focusing groove on the lens base, thereby clamping the lens base.

[0009] In some embodiments, the mounting slot is configured as a threaded slot, and the support column is provided with a threaded section adapted to the threaded slot. The threaded slot and the threaded section of the support column cooperate to facilitate quick and easy installation of the support column, providing a stable installation effect. Furthermore, the depth of insertion of the support column into the mounting slot can be adjusted, thereby adjusting the height of a clip attached to the support column, thereby facilitating adjustment of the clip's tightness in clamping the mirror mount.

[0010] In some embodiments, a spring is disposed on the outer sleeve of the support column, with one end of the spring abutting against the bearing seat and the other end abutting against the clip. The spring serves as a support and buffer between the bearing seat and the clip, making the clip more stable in clamping the mirror holder.

[0011] In some embodiments, the support base is provided with a buffer member that extends away from the support base, and whose orthographic projection onto the support base overlaps with the orthographic projection of the clip onto the support base. Thus, when adjusting the depth of the support column inserted into the mounting slot, the buffer member can block the clip, achieving a buffering effect and preventing the clip from exerting excessive pressure on the mirror base and causing damage. The material of the buffer member can be the same as or different from the shape of the clip.

[0012] In some embodiments, the rotating platform is configured as a ball bearing, comprising an outer ring and an inner ring disposed within the outer ring, wherein the interior space of the inner ring forms the receiving groove. Relative rotation between the inner and outer rings of the ball bearing enables relative rotation between the lens mount and the lens, making the focus adjustment process smoother and thereby improving the stability of focus adjustment.

[0013] In some embodiments, the camera module further includes a circuit board, on which a driving circuit is provided; the photosensitive device is mounted on the circuit board and electrically connected to the driving circuit, and the lens is located on the side of the photosensitive device facing away from the circuit board. Based on this, during the focusing process, the circuit board of the camera module is fixed under the rotating table, and the lens barrel is extended into the receiving slot of the rotating table. In this way, the lens will not be blocked, and the lens barrel is driven to rotate by the rotation of the rotating table, thereby driving the lens closer to or away from the photosensitive device to achieve focal length adjustment. Based on this, by electrically connecting the circuit board to the display device, the focus adjustment status can be understood in real time through the clarity of the image output by the display device.

[0014] According to another aspect of the present application, a camera module adjustment device is provided, comprising the camera module adjustment jig as described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In electronic devices such as mobile phones, camera modules typically include optical lenses and photosensitive chips. During the camera module assembly process, the distance between the optical lens and the photosensitive chip must be adjusted to determine the position of the optical lens where the image is clear in order to complete focusing. For example, during the focus adjustment process of a Time of Flight (TOF) camera, image clarity requires manual adjustment. However, current focusing jigs require removal to check the focus status during the focusing process, which is time-consuming and labor-intensive, reducing the efficiency of lens focus testing.

[0032] In order to solve the above problems, the present application provides a camera module adjustment jig, which is provided by setting a rotating table rotatably connected to the supporting seat on the supporting seat, using the rotating table to accommodate the camera module placed on the supporting seat, and using the clamping mechanism on the supporting seat to clamp the lens barrel of the camera module, so that when the rotating table rotates relative to the supporting seat, the lens barrel of the camera module can drive the lens to move relative to the photosensitive device, thereby realizing the adjustment of the focal length. In this way, the focus adjustment status can be understood in real time through a display device electrically connected to the driving circuit of the camera module.

[0033] Figure 1 A structural schematic diagram of a camera module adjustment fixture in one embodiment of the present application is shown. Figure 2 A structural schematic diagram of another perspective of the camera module adjustment fixture in one embodiment of the present application is shown.

[0034] See Figure 1 and Figure 2 One embodiment of the present application provides a camera module adjustment jig for adjusting a camera module 10, wherein the camera module 10 includes a photosensitive device, a lens barrel, and a lens. The camera module adjustment jig includes a supporting base 20, a rotating platform 30, and a clamping mechanism 40. The supporting base 20 is used to support the camera module 10. The rotating platform 30 is disposed on the supporting base 20 and can rotate relative to the supporting base 20 around a preset axis. The rotating platform 30 is provided with a receiving groove that passes through the rotating platform 30 and is used to accommodate the camera module 10. The clamping mechanism 40 is disposed on the supporting base 20 and is configured to clamp the lens barrel so that the lens and the photosensitive device can move closer to or farther away from each other as the rotating platform 30 rotates relative to the supporting base 20.

[0035] The camera module adjustment jig provided in the embodiment of the present application is configured by providing a rotating platform 30 and a clamping mechanism 40 on a support base 20, and providing a receiving groove on the rotating platform 30 so that the camera module 10 on the support base 20 can be accommodated in the receiving groove. Furthermore, the clamping mechanism 40 is used to clamp the lens barrel so that when the rotating platform 30 rotates relative to the support base 20, the lens located in the lens barrel can move closer to or further away from the photosensitive device as the lens barrel rotates, thereby achieving focal length adjustment. Based on this, by electrically connecting the driving circuit of the camera module 10 to a display device, the focus adjustment status can be understood in real time based on the clarity of the image output by the display device.

[0036] Optionally, the rotating platform 30 is arranged in a circular ring shape, and the preset axis coincides with the central axis of the rotating platform 30. It is understood that the lens barrel of a common camera module 10 is usually cylindrical, and therefore the camera module 10 as a whole is cylindrical. Based on this, setting the rotating platform 30 in a circular ring shape and aligning the preset axis with the central axis of the rotating platform 30 can improve the space utilization within the rotating platform 30.

[0037] In some embodiments, the lens barrel is provided with a focusing groove, and the clamping mechanism 40 has a snap joint 41, the end of which, facing away from the support base 20, snaps into engagement with the focusing groove. When the snap joint 41 of the clamping mechanism 40 snaps into engagement with the focusing groove on the lens barrel, the clamping mechanism 40 is provided on the support base 20, so that the lens barrel is fixed relative to the support base 20, while the lens base can be fixed to the rotating stage 30. Based on this, when the rotating stage 30 rotates relative to the support base 20, the lens barrel rotates relative to the lens base, thereby achieving focal length adjustment.

[0038] Optionally, the camera module 10 also includes a shell, which is cylindrical in shape, with a photosensitive device mounted on the shell, and a lens barrel mounted in the shell and threadedly connected to the shell. In this way, by rotating the lens barrel to move the lens barrel relative to the shell, the distance between the lens mounted in the lens barrel and the photosensitive device mounted on the shell can be changed, thereby achieving focal length adjustment.

[0039] In some embodiments, the lens barrel is provided with a plurality of focusing grooves spaced apart along its circumference, and the clamping mechanism 40 includes a plurality of snap connectors 41, each corresponding to one of the plurality of focusing grooves. The engagement of the plurality of snap connectors 41 with the plurality of focusing grooves allows the clamping mechanism 40 to more securely clamp the lens barrel, thereby ensuring better stability during focusing.

[0040] Optionally, multiple focusing grooves are evenly spaced along the circumference of the lens base. This allows the clamping force of the clamping mechanism 40 on the lens base to be evenly distributed, further improving the stability of the clamping process. For example, in one embodiment, there are two focusing grooves, which are symmetrically distributed at both ends of the lens base in the radial direction, thereby facilitating the clamping mechanism 40 to stably clamp the lens base.

[0041] In some embodiments, the support base 20 is provided with a mounting slot; the clamping mechanism 40 includes a support column 42 and a clip 43. One end of the support column 42 is mounted in the mounting slot, and the other end extends away from the support base 20. The clip 43 is connected to the support column 42, and the length of the clip 43 extends perpendicular to the extension direction of the support column 42 to form a clamping joint 41. When the camera module 10 is supported on the support base 20 and accommodated in the accommodating slot of the rotating stage 30, the clip 43 connected to the support column 42 is pressed down from above the camera module 10, so that the clip 43 engages with the focusing groove on the lens base, thereby clamping the lens base.

[0042] In one optional embodiment, the upper surface of the mirror base is provided with a groove that extends through the side surface of the mirror base. This allows the clip 43 to overlap the groove, achieving a snap connection between the clip connector 41 and the groove. In another optional embodiment, the upper surface of the mirror base is provided with a groove. The end of the clip 43, away from the support column 42, is bent downward and inserted into the groove, achieving a snap connection between the clip 43 and the groove, thereby clamping the mirror base. Optionally, the clip 43 is made of metal, such as iron or stainless steel. Optionally, the clip 43 is in the shape of an elongated strip.

[0043] In some embodiments, the mounting slot is configured as a threaded slot, and a threaded section that mates with the threaded slot is provided on the support column 42. The threaded slot and the threaded section of the support column 42 cooperate to facilitate quick and easy installation of the support column 42, providing a stable installation effect. Furthermore, the depth of insertion of the support column 42 into the mounting slot can be adjusted, thereby adjusting the height of the clip 43 connected to the support column 42, thereby facilitating adjustment of the tightness with which the clip 43 grips the mirror mount.

[0044] Optionally, the cross-sectional shape of the support column 42 is circular, and an operating head is provided on the end of the support column 42 facing away from the bearing seat 20. The diameter of the operating head is larger than the diameter of the support column 42. In this way, the operator can adjust the depth of the support column 42 inserted into the installation groove through the operating head, thereby improving the comfort of operation.

[0045] Optionally, a spring 421 is provided on the outside of the support column 42, and one end of the spring 421 abuts against the supporting seat 20, and the other end abuts against the buckle 43. In this way, the spring 421 can play a supporting and buffering role between the supporting seat 20 and the buckle 43, so that the clamping of the buckle 43 to the mirror seat is more stable.

[0046] Optionally, a buffer member 21 is provided on the support base 20. The buffer member 21 extends away from the support base 20, and the orthographic projection of the buffer member 21 toward the support base 20 overlaps with the orthographic projection of the clip 43 toward the support base 20. Therefore, when adjusting the insertion depth of the support column 42 into the mounting slot, the buffer member 21 can block the clip 43, achieving a buffering effect, preventing the clip 43 from exerting excessive pressure on the lens base and causing damage to the lens base. The material of the buffer member 21 and the shape of the clip 43 can be the same or different.

[0047] In some embodiments, the rotating platform 30 is configured as a ball bearing 31. The ball bearing 31 comprises an outer ring and an inner ring disposed within the outer ring. The inner space of the inner ring forms a receiving groove. Ball bearing 31 is a type of rolling bearing. Spherical alloy steel balls are mounted between the inner and outer steel rings. This rolling motion reduces friction during power transmission and improves the efficiency of mechanical power transmission. The relative rotation between the inner and outer rings of the ball bearing 31 enables relative rotation between the lens mount and the lens, making focus adjustment smoother and improving focus adjustment stability.

[0048] Figure 3 A structural schematic diagram of a camera module adjustment fixture in another embodiment of the present application is shown.

[0049] See Figure 2 and Figure 3 In some embodiments, the camera module 10 further includes a circuit board 11, on which a driving circuit is provided; the photosensitive device is mounted on the circuit board 11 and electrically connected to the driving circuit, and the lens is located on the side of the photosensitive device facing away from the circuit board 11. During the focusing process, the circuit board 11 of the camera module 10 is fixed under the rotating table 30, and the lens barrel is extended into the receiving groove of the rotating table 30. In this way, the lens will not be blocked, and the lens barrel is driven to rotate by the rotation of the rotating table 30, thereby driving the lens closer to or away from the photosensitive device to achieve focal length adjustment. Based on this, by electrically connecting the circuit board 11 to the display device, the focus adjustment status can be understood in real time through the clarity of the image output by the display device.

[0050] See Figures 1 to 3 In one embodiment, the camera module 10 includes a housing, a circuit board 11, a photosensitive device, a lens barrel, and a lens. The housing is cylindrical; the circuit board 11 is provided with a drive circuit, the photosensitive device is mounted on the circuit board 11 and is electrically connected to the drive circuit on the circuit board 11, and the circuit board 11 is mounted on the housing; the lens barrel is mounted within the housing and is threadedly connected to the housing; the lens is mounted within the lens barrel and is positioned opposite the photosensitive device, and the lens barrel is provided with a focusing groove.

[0051] The camera module adjustment jig includes a support base 20, a ball bearing 31, and a clamping mechanism 40. The support base 20 is used to support the camera module 10. The ball bearing 31 and the clamping mechanism 40 are both located on the support base 20. The ball bearing 31 includes an outer ring and an inner ring located within the outer ring. The interior space of the inner ring forms a receiving groove for accommodating the camera module 10 on the support base 20. The clamping mechanism 40 includes a support column 42 mounted on the support base 20 and a clasp 43 connected to the support column 42. The support column 42 can move relative to the support base to adjust the height of the clasp 43.

[0052] During the focusing process, the camera module 10 is placed on the supporting seat 20, the ball bearing 31 is placed on the circuit board 11 of the camera module 10, and the housing of the camera module 10 is accommodated in the accommodating groove, and then the buckle 43 of the clamping mechanism 40 is clamped with the focusing groove on the lens barrel. At this time, the lens barrel clamped by the buckle 43 is fixed relative to the supporting seat 20. In this way, the housing of the camera module 10 is fixed to the ball bearing 31 by clamping or other means, and the housing is driven to rotate relative to the lens barrel by rotating the ball bearing 31, thereby achieving focal length adjustment. The camera module adjustment jig provided in the embodiment of the present application has a simple structure, is easy to process and form, and does not affect the amount of light entering the camera module 10 during the focusing process, thereby ensuring the accuracy of the current parameters during the focusing process. In addition, since the connection method between the clamping mechanism 40 and the lens barrel is simple and flexible, the camera module adjustment jig can be applied to different camera modules 10, thereby improving its application range and reducing costs.

[0053] Based on the same invention purpose, the present application also provides a camera module adjustment device. In one embodiment of the present application, the camera module adjustment device includes the camera module adjustment fixture in the above embodiment.

[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application.
