The invention discloses a kind of anti-scratch scraper, including rack (2), the scraper (4) for being fixed in the rack (2) and being lifted by power set, and it is arranged on the circuit board (6) of the underface of the scraper (4), it is characterized in that, further include：External part (8), it is fixed on the side of the scraper (4), its horizontal direction stretches out the circuit board (6) and scraper (4), and the external part bottom is less than the bottom surface of the scraper (4) and is directly provided with adjustable difference in height；Position sensor (10), it is fixed on the side of the circuit board (6) and positioned at the underface of the external part (8), the bottom of the external part (8) is more than the bottom surface of the scraper (4) to the distance of the circuit board (6) upper surface with the distance of the position sensor (10) upper surface, when the position sensor (10) touches object, the power set stop motion is controlled.In the present invention, the distance of external part body (16) and circuit board (6) ensures there are enough frictions between scraper (4) and circuit board (6), while ensures that scraper (4) is not scratched.
Description
Technical field
The present invention relates to a kind of anti-scratch scraper.
Background technology
In the prior art in circuit board printing process, the process of scraper work is that important, current printing machine is scraped
Knife be there are problems that：At work, it is all that one-part form directly declines that scraper declines mode to circuit board press, passes through outside
Mechanical device is directly issued to working region, but current decline mode is worked there are following some problems due to scraper
Object circuit board is more demanding to operating accuracy, and scraper is directly declined there are precision is not high with current method, and easily right
Circuit board causes to damage, and is not easy to production needs.
The content of the invention
The object of the present invention is to provide a kind of doctor blade system that can be prevented that circuit board is scraped off and can guarantee that printing effect.
To solve the above problems, the present invention provides a kind of anti-scratch scraper, including rack, be fixed in the rack and
The scraper lifted by power set, and it is arranged on the circuit board of the underface of the scraper, it is characterised in that further include：
- external part, is fixed on the side of the scraper, its horizontal direction stretches out the circuit board and scraper, the stretching
End bottom is less than the bottom surface of the scraper and is directly provided with adjustable difference in height；
- position sensor, is fixed on the side of the circuit board and positioned at the underface of the external part, the external part
The distance of bottom and the position sensor upper surface be more than the bottom surface of the scraper to the distance of the circuit board upper surface,
When the position sensor touches object, the power set stop motion is controlled.
As a further improvement on the present invention, the side of the scraper is equipped with a vertical sliding slot, and the external part includes
The horizontally disposed and connecting rod that can be slided in the sliding slot and it is connected to the external part in the connecting rod and being vertically arranged
Body, the connecting rod is equipped with external screw thread, and a nut is threaded with external screw thread, and the nut is located at the external part sheet
Between body and scraper.
As a further improvement on the present invention, the power set are lifting motor.
As a further improvement on the present invention, the power set are lifting cylinder.
The beneficial effects of the present invention are the distance of the bottom of external part and the position sensor upper surface is more than described
The bottom surface of scraper to the upper surface of the circuit board distance, after scraper into contact is to circuit board, continue to push it is certain away from
From stopping, so as to ensure that scraper directly there are enough contacts with circuit board, ensure printing effect, and it is unlikely under the fixed value
Weighed wounded in by circuit board.
Brief description of the drawings
Fig. 1 is the structure diagram of the present invention；
Wherein：2- racks；4- scrapers；6- circuit boards；8- external parts；10- position sensors；14- connecting rods；16- stretches out

Embodiment
The embodiment of the present invention is described in further detail below.
As shown in Figure 1, the present invention includes rack 2, the scraper 4 for being fixed in the rack 2 and being lifted by power set,
And it is arranged on the circuit board 6 of the underface of the scraper 4, it is characterised in that further include：
- external part 8, is fixed on the side of the scraper 4, its horizontal direction stretches out the circuit board 6 and scraper 4, described
8 bottom of external part is less than the bottom surface of the scraper 4 and is directly provided with adjustable difference in height；
- position sensor 10, is fixed on the side of the circuit board 6 and positioned at the underface of the external part 8, described to stretch
The distance of the bottom of outlet 8 and 10 upper surface of position sensor is more than the bottom surface of the scraper 4 to 6 upper table of circuit board
The distance in face, when the position sensor 10 touches object, controls the power set stop motion.
As a further improvement on the present invention, the side of the scraper 4 is equipped with a vertical sliding slot, and the external part 8 wraps
Include the horizontally disposed and connecting rod 14 that can be slided in the sliding slot and be connected in the connecting rod 14 and be vertically arranged
External part body 16, the connecting rod 14 are equipped with external screw thread, and a nut 18 is threaded with external screw thread, 18, the nut
Between the external part body 16 and scraper 4.
As a further improvement on the present invention, the power set are lifting motor.
As a further improvement on the present invention, the power set are lifting cylinder.
The concrete operating principle of the present invention is as follows：
(1) the mobile link bar 14 in sliding slot, so that the distance that external part body 16 arrives position sensor 10 is adjusted, to set
Certain fixed value, tightens nut 18 so that nut 18 produces enough frictional force with 4 side of scraper, prevents connecting rod 14 from loosening；
(2) linear motor driving scraper 4 declines, and is just contacted to circuit board 6；
(3) linear motor continues to decline, and until external part body 16 is contacted with position sensor 10, control linear motor is transported
Dynamic, so far, scraper 4 is adjusted and finished, and the distance of external part body 16 and circuit board 6 ensures to have between scraper 4 and circuit board 6 enough
Friction, while ensure that scraper 4 is not scratched.
A kind of above example only present invention embodiment therein, its description is more specific and detailed, but can not
Therefore it is interpreted as the limitation to the scope of the claims of the present invention.It should be pointed out that for those of ordinary skill in the art,
Without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection model of the present invention
Enclose.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
