Abstract
The invention discloses a kind of circuit board with 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) and control device (10), the control device (10) include the first connecting plate (12) and the second connecting plate (14) for being horizontally fixed on the circuit board (6) side.In the present invention, when scraper (4) is moved downwardly to the value of setting, the pressure of generation acts on after the attraction on magnetic conductivity fixed block (18) deformation drag for being more than spring (16) with magnet (20), make magnetic conductivity fixed block (18) absorption on magnet 20, contact-making switch is contacted with magnet (20), controls power set stop motion.So that scraper (4) directly there are enough contacts with circuit board (6), ensure printing effect, and be unlikely to weigh wounded circuit board (6) again, solve the problems, such as to run into the prior art.
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 circuit board with anti-scratch scraper, including rack, be fixed on it is described
The scraper lifted in rack and 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 flushed with the bottom surface of the scraper；
- control device, it includes the first connecting plate and the second connecting plate that are horizontally fixed on the circuit board side, institute
State the first connecting plate be located at second connecting plate surface and between connected by spring, first connecting plate with it is described
The upper surface of circuit board is concordant, and the opposite side of first connecting plate and the second connecting plate is respectively equipped with magnetic conductivity fixed block and magnetic
The sum of iron, the maximum pressure that the magnetic attracting force that the magnet is acted on the magnetic conductivity fixed block is set with the scraper is big
In the resistance of the camber of spring, the magnetic conductivity fixed block lower surface is additionally provided with contact-making switch, and the contact-making switch is contacted
When, control the power set to be stopped.
As a further improvement on the present invention, the power set are straight line 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 present invention in, when scraper be moved downwardly to setting value when, the pressure of generation with
The attraction that magnet is acted on magnetic conductivity fixed block is more than the deformation drag of spring afterwards, makes the absorption of magnetic conductivity fixed block in magnetic
On iron, contact-making switch is contacted with magnet, controls power set stop motion.So that scraper and circuit board directly have it is enough
Contact, ensures printing effect, and is unlikely to weigh wounded circuit board again, solves the problems, such as to run into the prior art.

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 flushed with the bottom surface of the scraper 4；
- control device 10, its first connecting plate 12 for including being horizontally fixed on 6 side of circuit board and the second connection
Plate 14, first connecting plate 12 be located at the surface of second connecting plate 14 and between connected by spring 16, described
One connecting plate 12 is concordant with the upper surface of the circuit board 6, the opposite side point of 12 and second connecting plate 14 of the first connecting plate
Not She You magnetic conductivity fixed block 18 and magnet 20, the magnetic attraction acted on the magnetic conductivity fixed block 18 of the magnet 20
The sum of maximum pressure of power and the scraper 4 setting is more than the resistance of the spring 16 deformation, under the magnetic conductivity fixed block 18
Surface is additionally provided with contact-making switch, when the contact-making switch is contacted, controls the power set to be stopped.
In the present invention, when scraper 4 is moved downwardly to the value of setting, the pressure of generation acts on magnetic conductivity with magnet 20 and consolidates
Determine the deformation drag that the attraction on block 18 is more than spring 16 afterwards, magnetic conductivity fixed block 18 is adsorbed on magnet 20, contact
Switch is contacted with magnet 20, controls power set stop motion.So that scraper 4 directly has enough contacts with circuit board 6,
Ensure printing effect, and be unlikely to weigh wounded circuit board 6 again, solve the problems, such as to run into the prior art.
As a further improvement on the present invention, the power set are straight line lifting motor.
Using linear motor as power set, movement is accurate, and controllability is strong.
As a further improvement on the present invention, the power set are lifting cylinder.
It is simple in structure using lifting cylinder as power set, it is easy to operate.
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.
