Description

Technical Field

[0001] The utility model belongs to the technical field of sensors, and particularly relates to a lens adjusting device and a white light sensor. Background Art

[0002] A white light sensor refers to a photoelectric sensor whose light source is a white light LED and the position of the emitting end lens is adjustable, so as to focus into light spots of different sizes at different distances. A movable lens is usually arranged at the emitting end of the white light sensor, and the position of the emitting end lens can be adjusted back and forth, so that light spots of different sizes can be focused at different distances, and the size of the light spots can be adjusted. However, the existing lens adjusting device adjusts the position of the lens by arranging a guiding shaft on the outer wall of the lens barrel and driving the lens barrel to move through the cooperation of the guiding shaft and the sliding groove of the mounting bracket. Since a sliding groove for cooperating with the guiding shaft needs to be opened, the processing difficulty is relatively high, and it is easy to be damaged after long-term use, resulting in a decrease in the adjustment stability.

[0028] Please refer to Figures 1 to 5, an embodiment of the present application provides a lens adjustment device, including a bracket 10, a lens barrel 20 for mounting a lens 50 and slidably arranged on the bracket 10 along a first direction a, an elastic connecting member 30 arranged on the bracket 10, an adjustment structure 40 slidably arranged on the bracket 10 along a second direction b, and a transmission member 60 connected to the lens barrel 20. The adjustment structure 40 has a guiding surface 4221. The elastic connecting member 30 and the guiding surface 4221 are arranged at intervals along the first direction a and are respectively located on opposite sides of the transmission member 60. The elastic connecting member 30 elastically abuts against the transmission member 60 to make the transmission member 60 contact the guiding surface 4221. The adjustment structure 40 can be driven by an external force and move along the second direction b, so that the guiding surface 4221 guides the transmission member 60 to reciprocate along the first direction a. The first direction a and the second direction b are arranged at an angle.

[0029] It can be understood that the lens adjustment device of the present application can be applied to a white light sensor, and the white light sensor further includes a transmitting element and a receiving element. The transmitting element is used to emit light to the lens 50. The light emitted by the transmitting element passes through the lens 50 and irradiates the object to be measured. The object to be measured reflects the light, and the light reflected by the object to be measured irradiates the receiving element. The receiving element receives the light reflected back by the object to be measured and converts the optical signal into an electrical signal, thereby realizing the detection of the object to be measured.

[0030] It can be understood that the transmitting element and the object to be measured can be arranged on opposite sides of the lens 50 along the first direction a. Therefore, through the lens 50 adjustment device of the present application, the lens 50 can be adjusted to reciprocate along the first direction a, so that the distance between the lens 50 and the transmitting element along the first direction a can be adjusted, so as to focus into light spots of different sizes at different distances, and the clarity of the light spots can be adjusted.

[0031] In the lens adjustment device provided by the present application, the elastic connecting member 30 makes the transmission member 60 always elastically contact the guiding surface 4221. When the adjustment structure 40 is pushed to move along the second direction b, the transmission member 60 can move along the guiding surface 4221, and then drive the lens barrel 20 and the lens 50 to reciprocate along the first direction a synchronously, realizing the adjustment of the position of the lens 50. And the lens 50 adjustment device provided by the present application only needs to guide the movement of the lens barrel 20 through the guiding surface 4221, without opening a guiding groove. Therefore, the processing difficulty of the lens 50 adjustment device can be reduced, the service life of the lens adjustment device can be improved, and the adjustment is smoother and more stable.

[0032] In a possible embodiment, the guiding surface 4221 is an inclined surface, and the inclined surface is inclined relative to the first direction a. Specifically, the first direction a can be perpendicular to the second direction b, and the inclined surface is inclined relative to both the first direction a and the second direction b.

[0033] It can be understood that the inclined surface is provided with a first contact end away from the elastic connecting member 30 and a second contact end close to the elastic connecting member 30 along the first direction a, and the lens barrel 20 is connected to a transmission member 60 in contact with the inclined surface. When the adjustment structure 40 is driven by an external force to move along the second direction b, the inclined surface also moves along the second direction b, and the inclined surface always maintains contact with the transmission member 60. Therefore, the inclined surface can guide the transmission member 60 to reciprocate between the first contact end and the second contact end to drive the lens barrel 20 to reciprocate synchronously along the first direction a, thereby adjusting the position of the lens 50 along the first direction a.

[0034] Specifically, when the adjustment structure 40 is driven by an external force to move forward along the second direction b, the transmission member 60 moves from the first contact end away from the elastic connection member 30 to the second contact end close to the elastic connection member 30; when the adjustment structure 40 is driven by an external force to move backward along the second direction b, the transmission member 60 moves from the second contact end close to the elastic connection member 30 to the first contact end away from the elastic connection member 30. It can be understood that the inclined surface can be a plane or an arc surface. The specific shape of the inclined surface is not limited in this application, as long as the inclined surface is inclined relative to the first direction a.

[0035] In another possible embodiment, the guide surface 4221 may be a parabolic arc surface, and the distance between a point on the arc surface and the surface of the adjustment structure 40 away from the elastic connector 30 gradually increases from 0 along the second direction b, reaches a maximum value, and then gradually decreases to 0. Therefore, when the adjustment structure 40 is driven by an external force to move along the second direction b, the guide surface 4221 also moves along the second direction b, and the guide surface 4221 always keeps in contact with the transmission member 60, so that the transmission member 60 first gradually moves away from the surface of the adjustment structure 40 away from the elastic connector 30, and when it reaches the maximum distance from the surface of the adjustment structure 40 away from the elastic connector 30, it gradually approaches the surface of the adjustment structure 40 away from the elastic connector 30, thereby adjusting the position of the lens barrel 20 along the first direction a.

[0036] In some embodiments, the lens barrel 20 includes a main body 21, a transmission member 60 is connected to the outer peripheral wall of the main body 21, the transmission member 60 is a cylindrical structure, and the axis of the transmission member 60 is perpendicular to the first direction a and the second direction b. Since the transmission member 60 is a cylindrical structure, the friction between the transmission member 60 and the guide surface 4221 can be reduced, preventing the movement of the lens barrel 20 from being stuck, thereby improving the adjustment efficiency.

[0037] In the embodiment of the present application, the main body 21 is a hollow cylindrical structure, that is, there is a cavity inside the main body 21, and the outer shape of the main body 21 is a cylindrical structure. The cavity inside the main body 21 can allow light to pass through, and the lens 50 is also arranged in the cavity, and the optical axis of the lens 50 is parallel to the first direction a.

[0038] In some embodiments, the elastic connecting member 30 includes a seat body 31 fixed to the bracket 10, a sliding rod 32 movably disposed in the seat body 31 along a first direction a, and a spring 33 sleeved on the sliding rod 32. The bracket 10 includes a mounting plate 13 spaced apart from the lens barrel 20 along the first direction a. One end of the spring 33 away from the adjusting structure 40 is connected to the mounting plate 13. The sliding rod 32 extends along the first direction a, and one end of the sliding rod 32 away from the mounting plate 13 abuts against the transmission member 60.

[0039] It can be understood that the plate surface of the mounting plate 13 can be perpendicular to the first direction a. Further, a circular flange 322 can be provided at one end of the sliding rod 32 away from the mounting plate 13. The circular flange 322 surrounds the sliding rod 32 in the circumferential direction. One end of the spring 33 away from the mounting plate 13 can abut against the circular flange 322, so as to limit the spring 33.

[0040] Further, the seat body 31 has a sliding space for the sliding rod 32 to move. A guiding groove 311 communicating with the sliding space is formed in the side wall of the seat body 31. The guiding groove 311 extends along the first direction a. A guiding portion 321 is provided at one end of the sliding rod 32 away from the mounting plate 13. The guiding portion 321 extends into the guiding groove 311 and is slidably connected with the guiding groove 311. Through the cooperation between the guiding portion 321 and the guiding groove 311, the movement of the sliding rod 32 can be guided, so as to ensure the straightness of the movement of the sliding rod 32.

[0041] Further, guiding grooves 311 communicating with the sliding space are formed in the left and right side walls of the seat body 31. Correspondingly, guiding portions 321 are provided on both sides of one end of the sliding rod 32 away from the mounting plate 13. The two guiding portions 321 cooperate with the two guiding grooves 311 respectively, so as to further enhance the guiding effect on the movement of the sliding rod 32 and effectively avoid the sliding rod 32 from shifting during the movement.

[0042] In some embodiments, the transmission member 60 is a cylindrical structure. The end surface of the sliding rod 32 facing the transmission member 60 is an arc surface. The arc surface is recessed relative to the transmission member 60 and the arc surface contacts the outer peripheral surface of the transmission member 60. Since the arc surface is recessed relative to the transmission member 60 and the arc surface contacts the outer peripheral surface of the transmission member 60, the sliding rod 32 and the transmission member 60 are better adapted, and the power transmission efficiency between the sliding rod 32 and the transmission member 60 is higher.

[0043] In some embodiments, the adjusting structure 40 includes an adjusting plate 41, an adjusting block 42, and a rotating rod 43. The adjusting plate 41 is connected to the bracket 10. The rotating rod 43 is movably disposed through the adjusting plate 41. The rotating rod 43 extends along the second direction b, and one end of the rotating rod 43 abuts against the adjusting block 42 to push the adjusting block 42 to move along the second direction b. The guiding surface 4221 is disposed on the adjusting block 42. By providing the adjusting structure 40, only by screwing the rotating rod 43 can drive the adjusting block 42 to move along the second direction b, thereby driving the lens barrel 20 to move along the first direction a. The adjusting method is simple, improving the convenience of adjustment. In addition, an elastic member is connected to the side of the adjusting block 42 facing away from the lens barrel 20. The elastic member extends along the second direction b.

[0044] In some embodiments, the adjusting block 42 includes a connecting portion 421 connected to the rotating rod 43 and two extending portions 422 connected to both sides of the connecting portion 421. The two extending portions 422 and the connecting portion 421 enclose a receiving space for receiving the lens barrel 20. The guiding surface 4221 is disposed on the extending portion 422. Transmission members 60 are disposed on both sides of the main body portion 21. The two extending portions 422 respectively abut against the two transmission members 60 on both sides of the main body portion 21. By providing the connecting portion 421 and the two extending portions 422 connected to both sides of the connecting portion 421, and the two extending portions 422 respectively abut against the two transmission members 60 on both sides of the main body portion 21, the lens barrel 20 can be kept balanced during movement, avoiding the lens barrel 20 from shifting during movement, ensuring the straightness of the movement of the lens barrel 20. And the two extending portions 422 are connected to both sides of the connecting portion 421, and the connecting portion 421 is connected to the rotating rod 43. Therefore, only by adjusting the rotating rod 43 can drive the two extending portions 422 to move synchronously, thereby simplifying the structure of the lens adjusting device and facilitating miniaturization.

[0045] In some embodiments, as Figure 1 shown, the bracket 10 has an installation cavity for receiving the lens barrel 20 and for allowing the lens barrel 20 to move, and a sliding groove 12 communicating with the installation cavity is formed on the bracket 10. The sliding groove 12 extends along the first direction a. The transmission member 60 passes through the sliding groove 12 and extends outward, so that the transmission member 60 can still contact the guiding surface 4221 after passing through the sliding groove 12.

[0046] By providing the sliding groove 12, the transmission member 60 passes through the sliding groove 12 and is slidably connected to the sliding groove 12. Through the cooperation of the transmission member 60 and the sliding groove 12, the movement of the transmission member 60 can be guided, thereby guiding the movement of the lens barrel 20 along the first direction a, and ensuring the straightness of the movement of the lens barrel 20.

[0047] Further, sliding grooves 12 communicating with the installation cavity 11 are formed in the left and right side walls of the bracket 10. Correspondingly, transmission members 60 are provided on both sides of the main body portion 21, and the two transmission members 60 are respectively engaged with the two sliding grooves 12, thereby further enhancing the guiding effect on the movement of the lens barrel 20 and effectively preventing the lens barrel 20 from shifting during movement.

[0048] In some embodiments, the lens barrel 20 further includes a mounting portion 23 connected to one end of the main body portion 21 along the first direction a. The mounting portion 23 is used for mounting the lens 50, and the mounting portion 23 is detachably connected to the main body portion 21. Therefore, the lens 50 can be conveniently disassembled and assembled, improving the convenience of disassembling and assembling the lens 50.

[0049] Further, the mounting portion 23 has a plurality of fastening portions 231 extending toward the main body portion 21. The plurality of fastening portions 231 are arranged in a circumferential direction around the main body portion 21. Each fastening portion 231 is provided with a fastening hole 2311. A plurality of fastening positions 211 corresponding to the fastening portions 231 one by one are provided on the outer peripheral wall of the main body portion 21. The fastening positions 211 are fastened and fixed to the fastening holes 2311, thereby realizing the connection between the mounting portion 23 and the main body portion 21.

[0050] The present application also proposes a white light sensor, which includes a lens adjusting device. The specific structure of the lens 50 adjusting device refers to the above embodiments. Since this white light sensor adopts all the technical solutions of the above all embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0051] As Figure 5 shown, the lens adjusting device can be arranged inside the housing of the white light sensor, and the rotating rod 43 of the lens adjusting device is exposed outside the housing of the white light sensor. The lens 50 is arranged corresponding to the light outlet of the white light sensor. Therefore, only by screwing the rotating rod 43 can the lens 50 be adjusted, and the adjustment method is simple and fast.

[0052] In addition, the white light sensor includes a transmitting element and a receiving element. The transmitting element is used to emit light to the lens 50. The light emitted by the transmitting element passes through the lens 50 and irradiates the object to be measured. The object to be measured reflects the light. The light reflected by the object to be measured irradiates the receiving element. The receiving element receives the light reflected back by the object to be measured and converts the optical signal into an electrical signal, and outputs the electrical signal, thereby realizing the detection of the object to be measured. Specifically, the transmitting element is a white light LED, and the receiving element is a photodiode.

[0053] In summary, for the lens adjusting device provided in the present application, the elastic connecting member 30 enables the transmission member 60 to always be in elastic contact with the guiding surface 4221. When the adjusting structure 40 is pushed to move along the second direction b, the transmission member 60 can move along the guiding surface 4221, thereby driving the lens barrel 20 and the lens 50 to reciprocate along the first direction a synchronously, realizing the adjustment of the position of the lens 50. Moreover, for the lens 50 adjusting device provided in the present application, the movement of the lens barrel 20 only needs to be guided by the guiding surface 4221, without the need to open a guiding groove. Therefore, the processing difficulty of the lens 50 adjusting device can be reduced, the service life of the lens adjusting device can be improved, and the adjustment is smoother and more stable.

[0054] The above are only optional embodiments of the present application and are not intended to limit the present application.
