Description
Technical field
The present invention relates to a kind of anti-scratch scrapers of circuit board.
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
Reach working region under mechanical device is direct, but there are following some problems for current decline mode, due to scraper work
Object circuit board is more demanding to operating accuracy, and scraper is directly declined with current method there are precision is not high, and is easy pair
Circuit board causes to damage, and is not easy to production needs.
Invention content
The object of the present invention is to provide a kind of doctor blade systems that circuit board can be prevented to be scraped off and can guarantee printing effect.
To solve the above problems, the present invention provides a kind of circuit board anti-scratch scraper, including rack, feature exists
In further including：
It is arranged in the rack and by the elevating lever of power plant driving lifting；
Be set in below the elevating lever and can vertical sliding loop bar；
It is fixed on the scraper of the loop bar lower end；
The circuit board being located at immediately below the scraper；
It is fixed on the elevating lever and horizontally disposed fixed plate；
The spring being connected between the bottom of the fixed plate and the top of the scraper；
It is connected to first limited block and the second limited block at the bottom of the fixed plate and the top of the scraper,
The spacing for being smaller than the fixed plate and the scraper of first limited block and the second limited block, first limited block
Vertical direction position it is adjustable.
As the further improvement of the present invention, first limited block is rod-like structure, and outer surface is equipped with external screw thread,
Part protrusion and rotatable adjusting nut are equipped in the fixed plate, first limited block connects with the adjusting nut screw thread
It connects.
As the further improvement of the present invention, the power plant is lifting motor.
As the further improvement of the present invention, the power plant is lifting cylinder.
The beneficial effects of the present invention are scraper moves downward, and oppresses circuit board with circuit board contacts, circuit board is given at this time
One upward reversed support force of scraper, this support force can drive scraper to move upwards, compressed spring, and then offset part
The pressure of effect on circuit boards, spring is during by compressive deformation, with the increase of deflection, leads to the support of its deformation
Power must increase, therefore the pressure acted on circuit boards is also to gradually increase, until the first limited block and second limit
Block contacts with each other.In this way, spring can greatly reduce the pressure protection circuit of circuit board moment as buffer gear
Plate is not scraped off, while by the first limited block and the second limited block, and setting maximum pressure ensures that scraper and circuit board have enough
Pressure.
Description of the drawings
Fig. 1 is the structural schematic diagram of the present invention；
Wherein：2- racks；4- elevating levers；6- loop bars；8- scrapers；10- circuit boards；11- springs；12- fixed plates；14-
One limited block；The second limited blocks of 16-；18- adjusting nuts.
Specific implementation mode
The specific implementation mode of the present invention is described in further detail below.
As shown in Figure 1, the present invention includes rack 2, which is characterized in that further include：
It is arranged in the rack 2 and by the elevating lever 4 of power plant driving lifting；
Be set in the lower section of the elevating lever 4 and can vertical sliding loop bar 6；
It is fixed on the scraper 8 of 6 lower end of the loop bar；
The circuit board 10 being located at immediately below the scraper 8；
It is fixed on the elevating lever 4 and horizontally disposed fixed plate 12；
The spring 11 being connected between the bottom of the fixed plate 12 and the top of the scraper 8；
It is connected to the first limited block 14 and second limit at the bottom of the fixed plate 12 and the top of the scraper 8
Position block 16, the spacing for being smaller than the fixed plate 12 and the scraper 8 of first limited block, 14 and second limited block 16,
The vertical direction position of first limited block 14 is adjustable.
Scraper 8 moves downward, and compressing circuit board 10 is contacted with circuit board 10, and circuit board 10 is upward to scraper 8 one at this time
Reversed support force, this support force can drive scraper 8 to move upwards, compressed spring 11, and then offset partial action in electricity
Pressure on road plate 10, spring 11 is during by compressive deformation, with the increase of deflection, causes its support force deformed must
It must increase, therefore the pressure acted on the circuit board 10 is also to gradually increase, until the first limited block 14 and second limits
Block 16 contacts with each other.In this way, spring 11 is used as buffer gear, and the pressure that can greatly reduce 10 moment of circuit board is protected
Protection circuit plate 10 is not scraped off, while by the first limited block 14 and the second limited block 16, setting maximum pressure ensure scraper 8 with
Circuit board 10 has enough pressure.
As the further improvement of the present invention, first limited block 14 is rod-like structure, and outer surface is equipped with outer spiral shell
Line, the fixed plate 12 is interior to be equipped with part protrusion and rotatable adjusting nut 18, first limited block 14 and the adjusting
Nut 18 is threadedly coupled.
As a further improvement on the present invention, the power plant is straight line lifting motor.
Using linear motor as power plant, movement is accurate, and controllability is strong.
As a further improvement on the present invention, the power plant is lifting cylinder.
It is simple in structure using lifting cylinder as power plant, it is easy to operate.
The above example only one such embodiment of the present invention, the description thereof 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
It encloses.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
