Abstract
The invention discloses a scraper system for a circuit board. The scraper system comprises a rack, a scraper which is fixed on the rack and is capable of lifting through a power plant, and a circuit board arranged below the scraper, wherein the scraper system also comprises a photoelectric sensor, light-emitting equipment, and a probe, wherein the photoelectric sensor is fixed on one side of the circuit board and is capable of receiving a light beam; when the photoelectric sensor cannot receive the light beam, the power plant is controlled to stop running; the light-emitting equipment and the photoelectric sensor are positioned on the same horizontal line; the light-emitting equipment can enable the light beam to irradiate on the photoelectric sensor; the probe is fixed on one side of the scraper; the probe extends out of the circuit board and the scraper in the horizontal direction; a vertical line where the probe is positioned is perpendicular to a connecting line between the light-emitting equipment and the photoelectric sensor; and the bottom of the probe is lower than the bottom surface of the scraper, and an adjustable height difference exists between the bottom of the probe and the bottom surface of the scraper. Due to the distance between the probe body and the scraper, enough friction between the scraper and the circuit board is ensured, and the scraper system can ensure that the scraper is not scraped.
Description
Technical field
The present invention relates to a kind of circuit board doctor blade system.
Background technology
In prior art, in circuit board printing process, the operation of scraper work is important, current sealBrush machine scraper exists some problems: circuit board press is in the time of work, and scraper decline mode is all one-part formDirectly decline, be directly issued to working region by external mechanical devices, but current decline mode existsSome problems below, because the object circuit board of scraper work is had relatively high expectations to operating accuracy, and scraper orderFront method directly declines and exists precision not high, and easily circuit board is caused to damage, is not easy to need of production.
Summary of the invention
The object of this invention is to provide and a kind ofly can prevent that circuit board from can be ensured again the scraper of printing effect by scratchSystem.
For addressing the above problem, the invention provides a kind of circuit board doctor blade system, comprise frame, fixingIn described frame and by the scraper of power set lifting, and be arranged on described scraper under electricityRoad plate, is characterized in that, also comprises:
-photoelectric sensor, is fixed on a side of described circuit board, can accept light beam, described photoelectric sensorIn the time that light beam cannot be accepted, control described power set stop motion;
-luminaire, is positioned on same level line with described photoelectric sensor, and described light-emitting device can be by lightBundle is radiated on described photoelectric sensor
-pop one's head in, be fixed on a side of described scraper, its horizontal direction is stretched out described circuit board and scraper, instituteThe vertical curve of stating probe place is vertical with the line of described luminaire and described photoelectric sensor, described spyHead bottom is lower than the bottom surface of described scraper, and between be provided with adjustable difference in height.
The side of described scraper is provided with a vertical chute as a further improvement on the present invention, described probe bagDraw together connecting rod horizontally disposed and that can slide and be connected on described connecting rod and vertically in described chuteThe probe body arranging, described connecting rod is provided with external screw thread, and the nut that has been threaded above, described spiral shellFemale between described probe body and scraper.
As a further improvement on the present invention, described power set are lifting motor.
Beneficial effect of the present invention is, probe is lower than the bottom surface of scraper and be set as fixed value, when scraper connectsAfter contacting circuit board, continue to press down certain distance and stop, thereby ensure that scraper and circuit board directly have footEnough contacts, ensure printing effect, and are unlikely to circuit board to weigh wounded under this fixed value.

Detailed description of the invention
Below the specific embodiment of the present invention is described in further detail.
As shown in Figure 1, the present invention includes frame 2, be fixed in described frame 2 and by power set liftingScraper 4, and be arranged on described scraper 4 under circuit board 6, it is characterized in that, also comprise:
-photoelectric sensor 10, is fixed on a side of described circuit board 6, can accept light beam, described photoelectric transferSensor 10, in the time cannot accepting light beam, is controlled described power set stop motion;
-luminaire 12, is positioned on same level line described light-emitting device energy with described photoelectric sensor 10Reach light beam irradiates on described photoelectric sensor 10
-pop one's head in 8, be fixed on a side of described scraper 4, its horizontal direction is stretched out described circuit board 6 and scraper4, the vertical curve at described probe 8 places and the line of described luminaire 12 and described photoelectric sensor 10Vertically, described probe 8 bottoms are lower than the bottom surface of described scraper 4, and between be provided with adjustable difference in height.
The side of described scraper 4 is provided with a vertical chute as a further improvement on the present invention, described probe 8Comprise connecting rod 14 horizontally disposed and that can slide and be connected to described connecting rod 14 in described chuteProbe body 16 upper and that vertically arrange, described connecting rod 14 is provided with external screw thread, and has been threaded one aboveNut 18, described nut 18 is between described probe body 16 and scraper 4.
As a further improvement on the present invention, described power set are lifting motor.
Specific works principle of the present invention is as follows:
(1) mobile link bar 14 in chute, thus the distance of probe body 16 to circuit board 6 regulated,For certain value of setting, fastening nut 18, makes nut 18 and scraper 4 sides produce enough frictional force, anti-Only connecting rod 14 is loosening;
(2) linear electric motors drive scraper 4 to decline, to just contacting with link plate;
(3) linear electric motors continue to decline, until probe body 16 blocks luminaire 12, now photoelectric transferSensor 10 cannot detect light beam, controls linear electric motors motion, and so far, scraper 4 regulates complete, and probe originallyThe distance of body 16 and circuit board 6 ensures there are enough frictions between scraper 4 and circuit board 6, guarantees scraper simultaneously4 are not scratched.
Above embodiment is only the present invention's a kind of embodiment wherein, and it describes comparatively concrete and detailed, butCan not therefore be interpreted as the restriction to the scope of the claims of the present invention. It should be pointed out that for this areaThose of ordinary skill, without departing from the inventive concept of the premise, can also make some distortion and changeEnter, these all belong to protection scope of the present invention. Therefore, the protection domain of patent of the present invention should be with appended powerProfit requires to be as the criterion.
