Description
Technical field:
The utility model relates to technical field of measuring equipment, refers in particular to a kind of optical measuring instrument.
Background technology:
In productive life, people are when measuring more tiny object, normally used measuring appliance is vernier caliper or spiral measuring instrument, its measuring accuracy is generally 0.05mm or 0.01mm, when needs more accurately during Measuring Object, need accurate more measuring appliance, and the grating measuring instrument is normally used a kind of more accurate equipment of measuring.It is desk-top that present grating measuring instrument mostly is slide calliper rule, and its slidably guide rail by quadrature moves worktable in a plane, and its mode that moves can realize by modes such as manual or screw rods, and measure displacement data by the grating chi.Be the precision that guarantees to measure, itself manufacturing accuracy of the guide rail that is used to slide requires very high, but it inevitably scale error and mismatch error can occur in the process of production and processing and assembling, so just brings certain error for the result who measures, and has influenced the precision of measuring.
Along with the development of micro-electromechanical technology, the precision positioning measurement has been proposed more and more higher requirement, produce has the higher optical gauge of measuring accuracy thereupon.In the existing optical gauge, mainly utilize a pick-up lens to be transferred on the micro computer, on the display screen of micro computer, catch point measurement with the measurement point shooting of measured object and with it.For this reason, the applicant has applied for No. 02248568.6 patent of China, and create under the prerequisite of this patent just by research and development for the utility model.
The utility model content:
The purpose of the utility model is to provide a kind of novel photoelectric measuring instrument, and simple in structure, processing and fabricating is easy, can be used for measuring and detecting, and is easy to operate, the precision height.
For achieving the above object, the utility model adopts following technical scheme:
A kind of novel photoelectric measuring instrument, comprise being installed on the support movably worktable and work computer that be provided with the mesh coordinate plate at the downside of worktable, also comprise: one first image is seized device, be arranged on the top of worktable, linearity is obtained the object image of worktable upside; One second image is seized device, is arranged on the below of worktable, and linearity is obtained the image of the mesh coordinate plate of worktable downside, and second image is seized device and seized device with first image and synchronous working; First image is seized device and is seized device with second image and all be connected with work computer.
Device seized by described second image and first image is seized device on same perpendicular line, and relative fixed.
Described mesh coordinate plate is made by reticle plate, which is provided with grid coordinate system.
The utility model is to be provided with at the worktable upper and lower that first image is seized device and second image is seized device, utilize two images to seize device and seize the object image of worktable upper and lower sides and the mesh coordinate image on the mesh coordinate plate respectively, on work computer, overlap two images then, can in work computer, measure object, it is convenient to measure, the precision height; The utility model also can be used for the usefulness of product detection, has the function of AOI (automated optical detection).
The utility model advantage again is simple in structure, and scientific and reasonable, cost of investment is low, and the operation operation is easy, and Maintenance and Repair are very convenient, improved the operation ratio and the operability of measuring equipment greatly, and the measuring process quality control is reliable and stable.
Description of drawings:
Accompanying drawing 1 is the utility model structural representation.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Consult shown in Figure 1, it is preferred embodiment of the present utility model, the utility model is relevant a kind of novel photoelectric measuring instrument, comprise and be installed on the support movably worktable 1 and work computer (not shown), downside at worktable 1 is provided with mesh coordinate plate 2, mesh coordinate plate 2 is made by reticle plate, which is provided with grid coordinate system, and grid coordinate system can see through worktable 1 and present.This photoelectric measuring instrument also comprises: one first image is seized device 3, is vertically set on the top of worktable 1, has scan function, can linear sweep the object image of getting the worktable upside; One second image is seized device 4, is vertically set on the below of worktable 1, also has scan function, can linear sweep the coordinate diagram picture of the mesh coordinate plate 2 of getting the worktable downside, and second image is seized device 4 and seized device 3 with first image and synchronous working; First image is seized device 3 and second image and is seized device 4 and be installed on the frame, all is connected with work computer.
In the present embodiment, device 4 seized by second image and first image is seized device 3 on same perpendicular line, and relative fixed, when realizing that worktable 1 moves, first image seize device 3 and second image seize device 4 about correspondence seize the upper and lower sides image of worktable 1 same position.
During work, object is placed on worktable 1 upside, drops in the grid coordinate system of mesh coordinate plate 2, and mesh coordinate is located.First image is seized device 3 and is had scan function, and fast linear is swept the combination picture of getting the worktable upside, obtains to be transferred to work computer behind the image; Equally, second image is seized device 4 and is also had scan function, and fast linear is swept the mesh coordinate image of getting the worktable downside, is transferred to work computer behind the image that obtains; Overlap two images then on work computer, form survey sheet, can measure object in work computer, it is convenient to measure, the precision height.The utility model also can be used for the usefulness of product detection, has the function of AOI (automated optical detection), and also having solved traditional AOI simultaneously can only scan image, does not have a defective of coordinate function.When traditional AOI detects automatically, machine is by camera autoscan PCB, images acquired, the solder joint of test and the qualified parameter in the database compare, through Flame Image Process, check out that PCB goes up defective, and defective is shown/mark, for maintenance personal's finishing by display or Automatic Logos.But when sweep velocity was fast, image will bently become, and lacks coordinate setting, also just can not be used for measuring.And the utility model utilization up and down first image seize the coordinate diagram picture that device 3 and second image are seized device 4 synchronous scanning object images and template, even bent the change takes place in object image and coordinate diagram picture, but bent the change is consistent, to also can utilize the point on the coordinate diagram picture to catch measurement after two picture registrations, functional and practicality more be better than traditional AOI product.
The utility model is simple in structure, and is scientific and reasonable, and cost of investment is low, and the operation operation is easy, and Maintenance and Repair are very convenient, improved the operation ratio and the operability of measuring equipment greatly, and the measuring process quality control is reliable and stable.
Certainly, more than diagram only is a better embodiment of the present utility model, be not to limit usable range of the present utility model with this, seize device 3, second image for first image and seize position relation between device 4 and the worktable 1, and mesh coordinate plate 2 other additional spacing assembling form and shape on worktable 1, all can think based on the utility model technology and so on like changing, this graphic giving unnecessary details of giving an example no longer one by one.So, everyly on the utility model principle, make equivalent change and all should be included in the protection domain of the present utility model.
