Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of protection of the invention.
As shown in Figure 1, a kind of focusing lens that the embodiment of the present invention provides, the second control loop 5 that these focusing lens comprise camera lens body 1, focus on for first control loop 2 and carrying out for adjustable lens body 1 of the focal length value of adjustable lens body 1, described first control loop 2 and the second control loop 5 are connected to drive unit.
By the first control loop and second control loop of drive unit electronic adjustment camera lens body, electric adjustable perfect square formula replaces existing artificial adjustment mode, very convenient, lower to the skill set requirements of commissioning staff, shortens debugging cycle.
Particularly, described drive unit is the first electro-motor 3 and the second electro-motor 6; Described first electro-motor 3 rotates for driving described first control loop 2; Described second electro-motor 6 rotates for driving described second control loop 5.Described first electro-motor 3 is fixedly connected with the first gear 4, and described first control loop 2 is fixedly connected with the 3rd gear, described first gear 4 and the 3rd gears meshing.Described second electro-motor 6 is fixedly connected with the second gear 7, and described second control loop 5 is fixedly connected with the 4th gear, described second gear 7 and the 4th gears meshing.
Usually, the first electro-motor 3, second electro-motor 6, first gear 4, second gear 7, the 3rd gear and the 4th gear are all positioned at the inside of housing 8, and the capture end of camera lens body 1 is positioned at the outside of housing 8.
As shown in Figure 2, described first electro-motor 3 and the second electro-motor 6 are all connected with control device.Described control device is the PC 10 that control card 9 is connected with described control card 9.
In use, instruction is sent to control card 9 by PC 10, send pulse signal by control card 9 to be rotated for the first control loop 2 controlling focal length value by the first gear 4 and the 3rd gear drive to the first electro-motor 3, first electro-motor 3, and then change the focal length value of camera lens.
Particularly, certain linear relationship is there is between the umber of pulse that the focal length value of camera lens and control card send, by this linear relationship, can according to the required focal length value adjusted to, the control card controlled by PC 10 sends corresponding pulse number, controls the focal length value that camera lens changes to needs.
After having adjusted the focal length value of camera lens, generally also need adjustment camera lens to blur-free imaging.At this moment, instruction is sent to control card 9 by PC 10, send pulse signal by control card 9 to be used for by the second gear 7 and the 4th gear drive the second control loop 5 that adjustable lens body 1 carries out focusing on to the second electro-motor 6, second electro-motor 6 and to rotate, until be adjusted to camera lens blur-free imaging.In lens focus process, by PC 10 display interface, observe camera lens image quality.
Electromotion focusing camera lens improves zoom lens at industrial circle, and particularly automaticity requires the range of application on higher machine vision equipment.Control electro-motor by PC and adjust lens focus value and focusing operation, greatly reduce the difficulty of manual debugging during practical application, improve debugging efficiency, reduce human cost simultaneously.Electromotion focusing achieves zoom with high to coke number precision, can realize micron-sized adjustment accuracy.
Present invention also offers a kind of industrial camera, this industrial camera comprises above-mentioned focusing lens.
In the application of actual industrial field, when camera lens focal length, object distance, and acquisition precision one timing, the turned position that camera lens carries out the second control loop focused on is fixing.That is, can by the command value of PC software real-time storage for the second control loop of focusing on and the first control loop for adjusting focal length, during the identical lens parameters of next demand, can directly call this command value by PC.Namely industrial camera possesses zoom level and preserves and historical data calling function parameters such as coke numbers, when being set to history parameters, directly calls.
In sum, focusing lens of the present invention pass through the first control loop and second control loop of drive unit electronic adjustment camera lens body, electric adjustable perfect square formula replaces existing artificial adjustment mode, the ease for operation of zoom lens when practical application and automaticity are significantly improved, improve because zoom lens cannot the limited problem of the application that brings of autozoom, and shorten debugging cycle, reduce adjustment difficulty, reduce the skill set requirements to commissioning staff.
