Description

Technical Field

[0001] The present disclosure relates to the technical field of camera focusing, and particularly to a focusing device and a focusing equipment. Background Art

[0002] Currently, with the continuous development of society, cameras are required in all walks of life, which makes the demand for cameras increasing. Before the cameras leave the factory, it is necessary to focus on the corresponding parameters of the cameras so that the cameras can meet the needs of customers. In the past, focusing on the cameras often required manually placing the cameras on the focusing equipment, making the focusing steps of the cameras time-consuming and laborious.

[0003] In response to this, the related art discloses a focusing equipment that clamps the camera by a manipulator for focusing. For example, as disclosed in Chinese Patent Document CN205982952U, a camera focusing device includes an in-and-out manipulator mechanism for clamping and conveying the camera, a camera focusing mechanism for clamping the camera and rotating the camera, a camera clamping mechanism for controlling the camera focusing mechanism to clamp or loosen the camera, and an up-and-down manipulator mechanism for controlling the up-and-down movement of the camera focusing mechanism. The camera clamping mechanism is fixed to the up-and-down manipulator mechanism, the camera focusing mechanism is fixedly supported by the camera clamping mechanism, and the in-and-out manipulator mechanism is arranged below the camera focusing mechanism.

[0004] However, when focusing the camera, the manipulator is used to clamp the camera and place it on the focusing equipment, and then the camera is clamped through the camera focusing mechanism.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0031] To better understand the technical solutions and beneficial effects of this disclosure, the following further describes this disclosure in detail with specific embodiments:

[0032] Combined with Figure 1 And Figure 2 , the focusing device 10 of an embodiment includes a focusing bracket 100, a lens focusing mechanism 200, a linear driving mechanism 400, a multi-axis workbench 300, and an R-axis adjustment disc assembly 500.

[0033] The focusing bracket 100 includes a base 120 and a connecting cross beam 110 fixed to the base 120. The linear driving mechanism 400 is disposed on the base 120, and the lens focusing mechanism 200 is slidably disposed on the connecting cross beam 110. The multi-axis workbench 300 is disposed at the power output end of the linear driving mechanism 400; the R-axis adjustment disc assembly 500 is disposed between the multi-axis workbench 300 and the lens focusing mechanism 200. The multi-axis workbench 300 is provided with a fixing position 370, and the R-axis adjustment disc assembly 500 is fixedly disposed at the fixing position 370. An end of the R-axis adjustment disc assembly 500 is provided with a lens placement area 5310, and the lens placement area 5310 is used to position the focusing lens.

[0034] It can be understood that since the linear drive mechanism 400 is arranged on the base 120, the lens focusing mechanism 200 is slidably arranged on the connecting cross beam 110, and the multi-axis workbench 300 is arranged at the power output end of the linear drive mechanism 400, the multi-axis workbench 300 can be driven by the linear drive mechanism 400 to be below the lens focusing mechanism 200. Also, because the R-axis adjustment disc assembly 500 is arranged between the multi-axis workbench 300 and the lens focusing mechanism 200, the R-axis adjustment disc assembly 500 is located below the focusing mechanism. When the camera is placed in the lens placement area 5310 at the end of the R-axis adjustment disc assembly 500, the rotation angle of the R-axis adjustment disc can be rotated, so as to adjust the angle parameters required by the camera on the R-axis adjustment disc assembly 500, and then the lens focusing mechanism 200 is used to focus the camera, so as to meet the parameters required by the camera.

[0035] It can be understood that compared with the prior art, in the above-mentioned focusing device 10, the R-axis adjustment disc assembly 500 is arranged between the multi-axis workbench 300 and the lens focusing mechanism 200, the R-axis adjustment disc assembly 500 is fixedly arranged at the end of the multi-axis workbench 300, and at the same time the multi-axis workbench 300 is slidably arranged on the linear drive mechanism 400, so that the R-axis adjustment disc assembly 500 rotates the camera and the lens focusing mechanism 200 for focusing and positioning, so as to meet the focusing parameters of the camera, improve the focusing efficiency of the camera, and at the same time can meet the focusing parameters required for the camera to leave the factory as much as possible.

[0036] It should be noted that the structure and testing method of the lens focusing mechanism 200 both belong to the prior art and will not be elaborated here.

[0037] Combined with Figure 1 With Figure 2As shown, in one embodiment, the R-axis adjustment disc assembly 500 includes a rotary adjustment disc 510, an adjustment base 520, and a placement table 530. The adjustment base 520 is fixedly arranged at the fixed position 370; the rotary adjustment disc 510 is rotatably connected to the adjustment base 520, and the placement table 530 is arranged on the rotary adjustment disc 510; scale lines are provided on the outer peripheral wall of the rotary adjustment disc 510, and alignment lines are provided on the adjustment base 520. It can be understood that the adjustment base 520 is arranged at the end of the multi-axis workbench 300, so that when the camera is placed on the R-axis adjustment disc assembly 500, the positional relationship between the camera and the lens focusing mechanism 200 can be adjusted through the multi-axis workbench 300. And because the rotary adjustment disc 510 provides the function of rotary adjustment, and at the same time the camera is placed on the placement table 530. Since the placement table 530 is arranged on the rotary adjustment disc 510, when the rotary adjustment disc 510 rotates, the placement table 530 will rotate accordingly. When the camera is placed on the rotary adjustment disc 510, and scale lines are provided on the outer peripheral wall of the rotary adjustment disc 510 and alignment lines are provided on the adjustment base 520, the camera can be accurately rotated and adjusted according to the values provided by the scale lines. At the same time, the alignment lines are used for alignment between the camera and the lens focusing mechanism 200. The camera can be rotated by the rotary adjustment disc 510 to align with the lens focusing mechanism 200 for lens focusing of corresponding parameters, and the focusing parameters required by the factory can be set by controlling the rotary adjustment disc 510.

[0038] Combined with Figure 1 and Figure 2As shown, further, the rotation adjustment disc 510 includes an adjustment disc body 5110, an adjustment rod 5120, and a fine adjustment knob 5130. The adjustment rod 5120 protrudes from the outer peripheral wall of the adjustment disc body 5110. An adjustment locking member 5210 protrudes from the side wall of the multi-axis workbench 300, and the adjustment locking member 5210 is provided with a receiving port 5211. A locking post 5220 protrudes from the outer peripheral wall of the adjustment base 520, and the locking post 5220 is connected to the adjustment locking member 5210 through the receiving port 5211. The fine adjustment knob 5130 protrudes from the outer peripheral wall of the adjustment base 520. It can be understood that by protruding the adjustment rod 5120 on the outer peripheral wall of the adjustment disc body 5110, the adjustment disc body 5110 can be rotated by driving the adjustment rod 5120, so that the camera in the lens placement area 5310 rotates. At the same time, an adjustment locking member 5210 protrudes from the side wall of the multi-axis workbench 300, and the locking post 5220 is connected to the adjustment locking member 5210 through the receiving port 5211. When the position of the camera is adjusted, the adjustment locking member 5210 can be fixed to the locking post 5220 by turning the knob. Because the locking post 5220 is connected to the adjustment base 520, and at the same time the adjustment disc body 5110 is above the adjustment base 520 and rotatably connected together. When the locking post 5220 of the adjustment base 520 is fixed, it is difficult for the adjustment disc body 5110 to rotate with the adjustment base 520, so that the rotation adjustment disc 510 cannot rotate. After adjusting the rotation angle, the rotation adjustment disc 510 is not likely to deviate in angle and affect the focusing parameters. The fine adjustment knob 5130 protrudes from the outer peripheral wall of the adjustment base 520, and the rotation precision difference of the rotation adjustment disc 510 can be adjusted by turning the fine adjustment knob 5130.

[0039] Combined with Figure 2 and Figure 3 As shown, in one embodiment, the lens placement area 5310 is provided on the end face of the placement table 530. The lens placement area 5310 is located below the lens focusing mechanism 200, and a plurality of clamping posts 5311 are provided on the periphery of the lens placement area 5310. It can be understood that the lens placement area 5310 is provided on the placement table 530, and at the same time, a plurality of clamping posts 5311 are provided on the periphery of the lens placement area 5310. The lens is placed in the lens placement area 5310, and the camera is fixed by the clamping posts 5311 on the periphery of the lens placement area 5310. When the rotation adjustment disc 510 rotates, the clamping posts 5311 on the periphery of the lens placement area 5310 can effectively prevent the camera from being displaced as the rotation adjustment disc 510 rotates, ensuring that the camera remains fixed during operation, ensuring the accuracy of focusing and focusing, fixing the camera by the clamping posts 5311 can reduce the focusing error caused by the unstable position of the camera, optimize the focusing effect of the camera, and improve the imaging quality.

[0040] Combined withFigure 1 and Figure 2 As shown, in one embodiment, the multi-axis workbench 300 includes a Y-axis moving base 310 and a Y-axis moving rod 320. The Y-axis moving base 310 is located between the linear drive mechanism 400 and the R-axis adjustment disc assembly 500. The peripheral wall of the Y-axis moving base 310 is provided with a Y-axis sliding block 3110, and the Y-axis moving rod 320 is rotatably connected to the Y-axis sliding block 3110. And the R-axis adjustment disc assembly 500 is arranged at the end of the Y-axis moving base 310, and the Y-axis moving base 310 slides back and forth relative to the linear drive mechanism 400. It can be understood that by arranging the Y-axis moving base 310 between the linear drive mechanism 400 and the R-axis adjustment disc assembly 500, and at the same time, the Y-axis moving base 310 is provided with a Y-axis sliding block 3110, and the Y-axis moving rod 320 is rotatably connected to the Y-axis sliding block 3110, when the Y-axis moving rod 320 is turned, it will abut against the Y-axis sliding block 3110, so that the Y-axis moving base 310 slides back and forth relative to the sliding base. Also, because the Y-axis moving base 310 and the R-axis adjustment disc assembly 500 are connected together, the relative position relationship between the R-axis adjustment disc assembly 500 and the lens focusing mechanism 200 in the front and back directions can be adjusted by the Y-axis moving rod 320, so that the R-axis adjustment disc assembly 500 can move back and forth to change its relative position to the lens focusing mechanism 200, enabling the camera focusing parameters to be flexibly changed.

[0041] As Figure 2 shown, in one embodiment, the multi-axis workbench 300 further includes an X-axis moving base 330 and an X-axis moving rod 340. The X-axis moving base 330 is arranged between the linear drive mechanism 400 and the Y-axis moving base 310. The peripheral wall of the X-axis moving base 330 is convexly provided with an X-axis sliding block 3310, and the X-axis moving rod 340 is rotatably connected to the X-axis sliding block 3310. And the Y-axis moving base 310 is arranged at the end of the X-axis moving base 330, and the X-axis moving base 330 slides left and right relative to the linear drive mechanism 400. It can be understood that by arranging the X-axis moving base 330 between the linear drive mechanism 400 and the Y-axis moving base 310, and at the same time, the peripheral wall of the X-axis moving base 330 is convexly provided with an X-axis sliding block 3310. When the X-axis moving rod 340 is turned and rotated, the X-axis moving base 330 can be made to move left and right relative to the linear drive mechanism 400 by the X-axis moving rod 340 abutting against the X-axis sliding block 3310, so that the camera can adjust the relative left and right positions of the R-axis adjustment disc assembly 500 and the lens focusing mechanism 200 according to requirements, and finely adjust the distance of the left and right movement of the R-axis adjustment disc assembly 500 to achieve the left and right position relationship that meets the camera focus parameters.

[0042] Combined with Figure 2 and Figure 3As shown, in one of the embodiments, the multi-axis workbench 300 further includes a Z-axis lifting base 350 and a Z-axis lifting rod 360. The Z-axis lifting base 350 is disposed between the linear drive mechanism 400 and the R-axis adjustment disc assembly 500. The Z-axis lifting rod 360 passes through the inner cavity of the Z-axis lifting base 350, and the Z-axis lifting rod 360 is rotatably connected to the Z-axis lifting base 350. The Z-axis lifting base 350 abuts against the linear drive mechanism 400. The Z-axis lifting base 350 moves up and down relative to the lens focusing mechanism 200. It can be understood that by disposing the Z-axis lifting base 350 between the linear drive mechanism 400 and the R-axis adjustment disc assembly 500, and the Z-axis lifting rod 360 passing through the inner cavity of the Z-axis lifting base 350, when the Z-axis lifting rod 360 is turned, the Z-axis lifting base 350 will rise or fall relative to the lens focusing mechanism 200, so that the placement table 530 for placing the camera rises or falls, enabling the camera to move closer to or farther away from the lens focusing mechanism 200. The focal length required for camera focusing can be set by changing the distance between the camera and the lens focusing mechanism 200.

[0043] As Figure 1 shown, specifically, the linear drive mechanism 400 includes a sliding platform 410 and a sliding bracket 420. The sliding bracket 420 is fixedly disposed on the base 120. The sliding platform 410 is slidably disposed on the sliding bracket 420, and the multi-axis workbench 300 abuts against the sliding platform 410. It can be understood that the sliding platform 410 is slidably disposed on the sliding bracket 420, and the multi-axis workbench 300 abuts against the sliding platform 410. Since the sliding platform 410 is slidably disposed on the sliding bracket 420, the sliding platform 410 can slide below the lens focusing mechanism 200 on the sliding bracket 420. Also, because the multi-axis workbench 300 abuts against the sliding platform 410 and the R-axis adjustment disc assembly 500 is disposed on the multi-axis workbench 300, the R-axis adjustment disc assembly 500 slides below the lens focusing mechanism 200.

[0044] As Figure 1As shown in the figure, further, the manual precise focusing device for the camera further includes a sliding driver 600 and a driving rod 700. The sliding bracket 420 is provided with a sliding channel 4210. One end of the driving rod 700 passes through the sliding channel 4210 and is connected to the end of the sliding bracket 420, and the other end of the driving rod 700 passes through the sliding channel 4210 and is connected to the sliding driver 600. It can be understood that by providing the sliding channel 4210 in the sliding bracket 420, and at the same time the driving rod 700 passes through the sliding channel 4210 and is connected to the end of the sliding bracket 420, and the other end of the driving rod 700 passes through the sliding channel 4210 and is connected to the sliding driver 600. The sliding driver 600 can be a motor or a pneumatic motor. By connecting the driving rod 700 to the sliding bracket 420, the driving rod 700 drives the sliding platform 410 on the sliding bracket 420 to move below the lens focusing mechanism 200 according to the power of the sliding driver 600, so as to realize the function that the multi-axis workbench 300 and the R-axis adjustment disc assembly 500 automatically move to the lens focusing mechanism 200.

[0045] This application also provides a focusing device, including the focusing device 10 of any of the above embodiments. It can be understood that by arranging the R-axis adjustment disc assembly 500 between the multi-axis workbench 300 and the lens focusing mechanism 200, the R-axis adjustment disc assembly 500 is fixedly arranged at the end of the multi-axis workbench 300, and at the same time the multi-axis workbench 300 is slidably arranged on the linear driving mechanism 400, so that the R-axis adjustment disc assembly 500 rotates the camera to perform focusing and positioning with the lens focusing mechanism 200, so as to meet the parameters required for camera focusing.

[0046] Compared with the prior art, the present disclosure has at least the following advantages:

[0047] 1) Since the linear driving mechanism 400 is arranged on the base 120, and the lens focusing mechanism 200 is slidably arranged on the connecting cross beam 110, and at the same time the multi-axis workbench 300 is arranged at the power output end of the linear driving mechanism 400, the multi-axis workbench 300 can be driven by the linear driving mechanism 400 to be below the lens focusing mechanism 200. And because the R-axis adjustment disc assembly 500 is arranged between the multi-axis workbench 300 and the lens focusing mechanism 200, the R-axis adjustment disc assembly 500 is located below the focusing mechanism. When the camera is placed in the lens placement area 5310 at the end of the R-axis adjustment disc assembly 500, the rotation angle of the R-axis adjustment disc can be rotated, so as to adjust the angle parameters required by the camera on the R-axis adjustment disc assembly 500, and then focus on the camera with the lens focusing mechanism 200, so as to meet the parameters required by the camera.

[0048] 2) Compared with the prior art, the above-mentioned focusing device 10 sets the R-axis adjustment disk assembly 500 between the multi-axis worktable 300 and the lens focusing mechanism 200. The R-axis adjustment disk assembly 500 is fixedly set at the end of the multi-axis worktable 300, and the multi-axis worktable 300 is slidably set on the linear drive mechanism 400, so that the R-axis adjustment disk assembly 500 rotates the camera and the lens focusing mechanism 200 to focus and position, thereby achieving the parameters that meet the camera focusing, improving the efficiency of the camera focusing, and at the same time can meet the focusing parameters that the camera needs to achieve when leaving the factory as much as possible.

[0049] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure. Therefore, the protection scope of the patent of the present disclosure shall be based on the attached claims.
