Disclosure of Invention

The to-be-solved technical problem of the utility model is to overcome the not enough of prior art, but provide a cell-phone center laser vision marking equipment of real-time detection laser marking condition.

The utility model discloses a concrete technical scheme as follows:

a laser visual marking device for a middle frame of a mobile phone comprises a laser, a visual camera, a visual light source, a conveyor belt and a visual refractor, wherein the laser and the visual refractor are arranged in parallel, and the visual refractor is provided with a plurality of refraction lenses which are arranged at an angle; the vision camera and the vision light source are respectively arranged right above and right below the vision refractor; the light path of the laser emitted by the laser device refracted by the refraction lens coincides with the light path of the illumination light captured by the vision camera.

Further, the inside of the visual refractor also comprises a scanning galvanometer.

Further, the vision camera is a high-speed CCD camera.

Further, the vision camera, the conveyor belt and the laser are connected with the same PLC control system.

Further, the touch display panel is also included.

Further, the device comprises two groups of lasers, visual refractors, visual cameras and visual light sources which are arranged along the conveyor belt.

Further, the conveyor belt is driven by a servo motor.

The utility model has the advantages as follows: the utility model provides a cell-phone center laser vision marking device is through setting up the vision refractor and integrating laser and vision light source to same light path, therefore the current condition of laser marking position can be observed in real time to the vision camera, when the mark trouble is beaten in the discovery, can in time shut down, avoids later the product to appear leaking after that and beats and the wrong condition of beating, has saved the cost, has improved the product percent of pass.

Detailed Description

The present invention will be further explained with reference to the drawings and examples. Wherein the showings are for the purpose of illustration only and are shown by way of illustration only and not in actual form, and are not to be construed as limiting the present patent; to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

Example 1

As shown in fig. 1, the utility model provides a laser visual marking device for a middle frame of a mobile phone, which comprises a laser 1, a visual camera 2, a visual light source 3, a conveyor belt 4, and a visual refractor 5, wherein the laser 1 and the visual refractor 5 are arranged in parallel, and the visual camera 2 and the visual light source 3 are respectively arranged right above and below the visual refractor; as shown in fig. 2, the optical path structure of the present invention is shown in the figure, marking laser is emitted from the laser 1, and changes direction after being refracted by the refractor 51, and acts on the middle frame 6 of the mobile phone; and the illumination light that the vision light source 3 sent passes through behind refractor 51 and refractor 52, transmits to vision camera 2 department, so vision camera 2 can observe the condition of the mark department of cell-phone center 6, and wherein refractor 51 is the dichroscope, and it can make the vision light of certain wavelength pass through completely and do not take place the reflection to make the illumination light completely send to refractor 52, and caught by vision camera 2, vision camera 2 is high-speed CCD camera in this embodiment.

So as to be said above, the laser emitted by the laser 1 in this embodiment partially coincides with the optical path of the illumination light captured by the vision camera 2, the specific working method of the present invention is as follows: the laser 1 emits laser refraction to mark the mobile phone middle frame 6, meanwhile, illumination light emitted by the visual light source is transmitted to the visual camera 2 along a light path, the visual camera can detect the real-time condition of the marked position of the mobile phone middle frame 6, if the conditions of error printing and missing printing occur in the marking process, the visual camera 2 can immediately capture the information and transmit the information to a matched image processing system, the image processing system sends error reporting information and transmits the error reporting information to a PLC control system, meanwhile, the laser and a servo motor for controlling a conveyor belt are both connected with the PLC control system, after receiving the error reporting information, the PLC immediately sends a work stopping command to the laser and the servo motor, and a worker can quickly observe what kind of faults occur from the touch display panel 7; because the vision camera 2 can capture the image information of the laser 1 while marking, and hysteresis does not exist, the detection and shutdown actions can be completed quickly, repeated mistaken-marking or missed-marking products are prevented from flowing through a working area, and the cost, and the time and labor consumed by the screening work are saved. The above computer programs needed for the image processing system and the PLC control system do not require substantial improvements over the prior art.

The utility model provides a cell-phone center laser vision marking device is through setting up the vision refractor and integrating laser and vision light source to same light path, therefore the current situation of laser marking position can be observed in real time to the vision camera, visual detection and beat do not have the hysteresis quality between the mark, when the mark trouble is beaten in the discovery, can in time shut down, avoid later the product appear after that leak beat with the wrong condition of beating, saved cost and time, improved the product percent of pass.

Example 2

The difference between the present embodiment and embodiment 1 is that the present embodiment further includes a scanning galvanometer in the structure of the vision refractor, where the scanning galvanometer includes an X-axis scanning galvanometer, a Y-axis scanning galvanometer, and a Z-axis scanning galvanometer, and the angle at which the laser needs to be incident is calculated according to the required marking position information before marking, so that the vibration amplitude of the X, Y, Z-axis scanning galvanometer is adjusted by the scanning galvanometer system, and the requirement of marking at multiple positions can be met.

Including two sets of lasers, vision refractor, vision camera, the vision light source of arranging along the conveyer belt in this embodiment, every is a set of mark of all being responsible for different positions, can effectively improve work efficiency.

It should be understood that the above examples are only for clearly illustrating the technical solutions of the present invention, and are not intended to limit the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
