Abstract
The invention discloses a novel scratch resistant scraper for a circuit board. The novel scratch resistant scraper comprises a rack, a lifting rod, a sleeve rod, a scrapper, a circuit board, a fixed plate, springs, first limiting blocks and second limiting blocks, wherein the lifting rod is arranged on the rack and driven to rise and descend by a power device, the sleeve rod is sleeved under the lifting rod and can vertically slide, the scrapper is fixedly at the lower end of the sleeve rod, the circuit board is arranged just below the scrapper, the fixed plate is fixed on the lifting rod and is arranged horizontally, the springs are connected between the bottom of the fixed plate and the top of the scrapper, the first limiting blocks and the second limiting blocks are connected to each of the bottom of the fixed plate and the top of the scrapper, the distance between the first limiting blocks and the second limiting blocks is smaller than the distance between the fixed plate and the scrapper, and the positions of the first limiting blocks in a vertical direction are adjustable. Through the above mode, the springs are taken as buffer mechanisms, the instantaneous stress of the circuit board can be greatly reduced to prevent the circuit board from being scratched; and meanwhile, through the first limiting blocks and the second limiting blocks, the maximum stress is set to ensure enough stress between the scrapper and the circuit board.
Description
Technical field
The present invention relates to the anti-scratch scraper of a kind of Novel circuit board.
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 the anti-scratch scraper of a kind of Novel circuit board, comprise frame,It is characterized in that, also comprise:
-be arranged in described frame and drive the elevating lever of lifting by power set;
-be set in below described elevating lever and the loop bar that can vertically slide;
-be fixed on the scraper of described loop bar lower end;
-be positioned at the circuit board under described scraper;
-be fixed on fixed head on described elevating lever and horizontally disposed;
-be connected to the spring between the bottom of described fixed head and the top of described scraper;
-be connected to the bottom of described fixed head and the top of described scraper the first limited block and second limitPosition piece, the spacing of described the first limited block and the second limited block is less than the spacing of described fixed head and described scraper,The vertical direction position of described the first limited block is adjustable.
As further improvement of the present invention, described the first limited block is rod shaped structure, and its outer surface is provided withExternal screw thread, in described fixed head, be provided with part protrude and rotating adjusting nut, described the first limited block withDescribed adjusting nut is threaded.
As further improvement of the present invention, described power set are lifting motor.
As further improvement of the present invention, described power set are lift cylinder.
Beneficial effect of the present invention is, scraper moves downward, and contacts compressing circuit board, now with circuit boardCircuit board is to one of scraper reverse support force upwards, and this support force can drive scraper to move upward, and pressesContracting spring, and then offset the pressure of partial action on circuit board, spring in compressed deformation process, withThe increase of deflection, cause the support force of its distortion increasing, therefore to act on the pressure on circuit boardPower also increases gradually, until the first limited block and the second limited block are in contact with one another. Adopt in this way,Spring, as buffer gear, can reduce the pressure protect circuit board of circuit board moment greatly not by scratch, withTime by the first limited block and the second limited block, set maximum pressure and ensure that scraper and circuit board have enough pressuresPower.

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, it is characterized in that, also comprise:
-be arranged in described frame 2 and drive the elevating lever 4 of lifting by power set;
-the loop bar 6 that is set in described elevating lever 4 belows and can vertically slides;
-be fixed on the scraper 8 of described loop bar 6 lower ends;
-be positioned at the circuit board 10 under described scraper 8;
-be fixed on fixed head 12 on described elevating lever 4 and horizontally disposed;
-be connected to the spring 11 between the bottom of described fixed head 12 and the top of described scraper 8;
-be connected to first limited block 14 Hes at the bottom of described fixed head 12 and the top of described scraper 8The second limited block 16, the spacing of described the first limited block 14 and the second limited block 16 is less than described fixed head 12With the spacing of described scraper 8, the vertical direction position of described the first limited block 14 is adjustable.
Scraper 8 moves downward, and contacts compressing circuit board 10 with circuit board 10, and now circuit board 10 is given scraper8 one reverse support forces upwards, this support force can drive scraper 8 to move upward, Compress Spring 11,And then offset the pressure of partial action on circuit board 10, spring 11 in compressed deformation process, along withThe increase of deflection, causes the support force of its distortion increasing, therefore to act on the pressure on circuit board 10Power also increases gradually, until the first limited block 14 and the second limited block 16 are in contact with one another. Adopt thisMode, spring 11, as buffer gear, can reduce the pressure protect circuit board of 10 moments of circuit board greatly10 by scratch, simultaneously by the first limited block 14 and the second limited block 16, sets maximum pressure and ensures to scrapeCutter 8 has enough pressure with circuit board 10.
As further improvement of the present invention, described the first limited block 14 is rod shaped structure, and its outer surface is establishedThere is external screw thread, in described fixed head 12, be provided with part and protrude and rotating adjusting nut 18, described the first limitPosition piece 14 is threaded with described adjusting nut 18.
