2, adopt slide unit and slide rail design, CCD camera can be made to move along two bit planes of X-axis and Y-axis, realize the detection of taking pictures of multiple product on a carrier, practical;
3, CCD camera is fixed on connecting link by support is sheathed, directly can realize the adjustment of the positions such as focusing to the variation of support upper-lower position, make convenient and reliable operation, be beneficial to the detection to different product during adjustment.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of instructions, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in embodiment of the present invention technology, be briefly described to the accompanying drawing used required in the description of embodiment technology below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is one-piece construction schematic diagram of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
With reference to shown in Fig. 1, a kind of High Precision Automatic pick-up unit, comprise portal frame 1, portal frame top is provided with the slide unit 2 moved in the X-axis direction, be connected with lead-screw drive mechanism 3 bottom slide unit, slide unit surface is provided with prolongs life platform 4, prolonging raw platform surface is provided with along Y direction line of motion guide rail 5, line slideway surface is provided with Connection Block 6, Connection Block side is connected with vertically disposed connecting link 7, connecting link is provided with CCD camera 8, CCD camera is connected with computer control system by wireless signal, and Connection Block opposite side is connected with gear train 9.
Wherein, prolong life platform side and be provided with the first limit switch 10, ensure the movement locus of Yan Shengpingtai, Connection Block side is provided with the second limit switch 11, ensures the movement locus of Connection Block.
Also be provided with light source 12 bottom connecting link, the use of auxiliary CCD camera, and light source is independently arranged, easy disassembly, is convenient to maintenance maintenance.
CCD camera is connected with connecting link by support 13, support comprises two fixed heads be arranged in parallel 14, fixed head is sheathed to be fixed on connecting link, fixed bar 15 is also provided with between two fixed heads, CCD camera is fixed on fixed bar, and the position coarse adjustment for CCD camera can directly realize the adjustment of support fixed position, and can rotate adjustment position of orientation, from machinery start with adjustment position can avoid to the adjustment of Systematical control part come simple and convenient, also avoid the damage of system program.
Gear train comprises driving belt 16, driving belt one end is set on engaged wheel 17, the other end is set on driving wheel, and driving wheel is connected with stepper motor 19, and engaged wheel is connected with bearing 20 by rotating shaft, bearing is fixed on Connection Block, Connection Block sandwiched is fixed on belt, and belt drive is more stable, and is easy to change, reduce use cost, improve service precision.
The principle of work of the present embodiment is as follows:
During use, directly be erected on device fabrication line by portal frame, then adjust the initial position of CCD camera, captured photo is sent in computer control system by wireless signal by CCD camera, computer control system carries out analysis identification to it, and judges.CCD camera complete first take pictures after, move to second product by slide unit to carry out repeating to take pictures uploading action, until whole drained one-tenth, then slide unit resets, gear train rotates, by Connection Block shift position to second row position, repeat the detection action of first row, realize two-dimensional space motion and detect, robotization performance is high, and transmission of wireless signals mode decreases the setting of cable, facilitate moving of CCD camera, avoid the complicated of equipment.
To the above-mentioned explanation of the disclosed embodiments, professional and technical personnel in the field are realized or uses the present invention.To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein can without departing from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
