Abstract
The utility model discloses a flat mirror reflection photographing positioning mechanism for a small-sized surface mounting crystal. The positioning mechanism comprises a camera mounted on a horizontal shifting device, a photographing light source for the camera is mounted on the camera, a tray is placed below a laser printer, a flat mirror is mounted between the laser printer and the tray and is mounted on a camera lens exposure area, and the camera is connected with the laser printer through a data line. A object (crystal) to be photographed is reflected into the camera by the flat mirror, so that the camera can be mounted outside a marking area, the laser printer is mounted above the object (crystal) to be photographed, the focal distance of the laser printer is within 200mm, the crystal can be marked after visual positioning, and marking accuracy is improved.
Description
Technical field
The utility model relates to the flat mirror reflects detent mechanism of taking pictures, particularly the flat mirror reflects detent mechanism of taking pictures on a kind of small-sized surface mount crystal laser marking machine.
Background technology
The surface mount crystal element and device is one of frequency electronic devices and components crucial in the information industry, be widely used in communication, computer, household electrical appliance and the various industrial electrical equipment, in Military Electronic Equipment, occupy equally critical role, put it briefly, every field that relates to Time And Frequency, crystal element and device is all essential.
In the production process of surface mount crystal, the complete crystal of each encapsulation will carry out the laser marking lettering for the marked product relevant information.Traditional mark lettering location adopts manual adjustments control laser marking machine to go out optical position, along with crystalline size dwindles (2.0mm*1.6mm or 1.6mm*1.2mm), manually the small-size product positioning accuracy request can't be satisfied in the control location, the phenomenon that font trains off often occurs, this just requires marking equipment to add vision positioning system.And along with product size is dwindled, the point of laser marking machine footpath also diminishes (0.04mm is following) thereupon, and no matter the laser marking machine of this kind point under directly is domestic or external, and focal length is all in 200mm.And the camera detent mechanism will be installed, because camera detent mechanism height itself is greater than 200mm, so the camera detent mechanism can't be directly installed on focal length 200mm below interior laser marking machine.In addition, along with product size is dwindled, the precision of mechanical action also has certain influence to product orientation.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provides the high small-sized surface mount crystrallographic plane mirror of a kind of mark precision to reflect the detent mechanism of taking pictures.
In order to achieve the above object, the technical solution adopted in the utility model is:
Small-sized surface mount crystrallographic plane mirror of the present utility model reflects the detent mechanism of taking pictures, it comprises the camera that is installed on the horizontally moving device, at described camera camera photograph light source is installed, below laser printer, be placed with charging tray, level crossing is installed between described laser printer and charging tray and described level crossing is installed in the camera lens irradiation area, described camera links to each other by data wire with laser printer.
The utility model has the advantage of: adopt the flat mirror reflects mode with illuminated object (crystal) by flat mirror reflects in camera, camera can be installed to outside the mark zone like this, and install in illuminated object (crystal) top focal length at 200mm with interior laser marking machine, make crystal can carry out again mark behind the vision location, improve the mark precision.For accurate location, place a fixing witness marker bar in the zone of taking a picture, the each photograph got relative position between crystal and the sign, so just can eliminate the camera position error that the mechanical action such as position movement causes of taking pictures, so that locate more accurate.
Description of drawings
Fig. 1 is the schematic diagram that small-sized surface mount crystrallographic plane mirror of the present utility model reflects the detent mechanism of taking pictures.
Fig. 2 is the instance graph of mechanism shown in Figure 1.
The specific embodiment
Below in conjunction with specific embodiment the utility model is described in detail.
Of the present utility model small-sized surface mount crystrallographic plane mirror as shown in the figure reflects the detent mechanism of taking pictures, it comprises the camera 1 that is installed on the horizontally moving device 6, at described camera camera being installed takes a picture with light source 5, below laser printer, be placed with charging tray 3, being used for the mark of carrying crystal uses, between described laser printer 2 and charging tray 3 level crossing 4 is installed and described level crossing is installed in the camera lens irradiation area, described camera and laser printer 2 link to each other by data wire.
Preferably place a fixing witness marker bar in the zone of taking a picture, the each photograph got relative position between crystal and the sign, so just can eliminate the camera position error that the mechanical action such as position movement causes of taking pictures, so that locate more accurate.
The angle of preferred described level crossing and horizontal direction is 45 degree.Like this mounting plane mirror imaging in the camera be equivalent to camera be installed in illuminated object (crystal) directly over, improve positioning accuracy.
In order to improve the shooting precision, the crystal of a mark is divided into three times takes.Reduce illuminated object (crystal) and take quantity, ratio between millimeter and the pixel is increased, and the shared pixel count of onesize illuminated object (crystal) increases, when the camera error is same pixel (such as 1 pixel) number, position error is less, and mark is more accurate.
The utility model increases small-sized surface mount crystrallographic plane mirror and reflects the detent mechanism of taking pictures under the prerequisite of originally only having laser marking machine.Working method is as follows: camera 1 is by the illuminated object (crystal) on the level crossing 4 reflection shooting charging trays 3, and after shooting was finished, the position of the illuminated object (crystal) on 1 pair of charging tray 3 of camera was carried out corresponding data and processed.After data were finished dealing with, camera 1 sent the physical location of the illuminated object on the charging tray 3 (crystal) to laser marking machine 2 by instruction.After laser marking machine 2 receives the position command and mark instruction that camera 1 transmits, accurately lettering is got to illuminated object (crystal) center on the charging tray 3.
Camera: take illuminated object (crystal) position and use.
Laser marking machine: use to the surperficial lettering of illuminated object (crystal).
Charging tray: hold illuminated object (crystal) and use.
Reflection level crossing: reflect the usefulness of taking pictures.Make camera can take the object of vertical direction on the horizontal direction, reduce the space that the camera detent mechanism takies on the vertical direction.
Camera is taken a picture and to be used light source: the camera light source of taking pictures is provided, can changes as required light source position and brightness.
The position movement assembly of taking pictures: change the camera position of taking pictures, take successively three positions of a mark.
The running of this mechanism is as follows:
At first, charging tray travel mechanism will treat that the mark crystal moves to marking machine below, and the camera position movement assembly of taking pictures acts as regent mobile camera moving to first count.After putting in place, camera automatically snaps, processes offset data and send the data to marking machine; After shooting was finished, the camera position movement assembly of taking pictures acted as regent mobile camera moving to second count, continued to take, send data, until after having taken all positions, the notice marking machine begins mark.After mark was finished, charging tray travel mechanism treated that with next part the mark crystal moves to the marking machine below, moves in circles.
