Description
Technical Field
The utility model relates to a SMT printing tool technical field especially relates to a novel printing machine scraper.
Background
The printing scraper is an indispensable tool for SMT factories and mainly has the functions of printing solder paste on a PCB (printed Circuit Board) to facilitate the pasting of parts by a chip mounter, the structural design of the scraper directly influences the printing quality, the printing quality particularly refers to the problem of short circuit, empty soldering and part shortage after a furnace, the design quality of the scraper also directly influences the operating cost of the factory, the printing quality comprises the problem of reasonably utilizing the consumption of the solder paste, the conventional scraper has the following defects that 1 the scraper is not provided with an adjusting device, most of the scraper is fixed in distance between fixed blocks, the scraper can only be suitable for PCBs with single length and wastes the solder paste, the distance of the fixed blocks can not be switched according to different lengths of the PCBs, so that the consumption of the PCBs with small printing length is increased, the residual solder paste with better viscosity needs to be replaced due to long-time use of the solder paste needs to be thrown away, 2 the scraper provided with the adjusting device generally adopts a round rod, the scraper piece passes through frictional force with the slide bar and fixes, when needs adjust the fixed block distance, does not adjust well, along with live time's extension, the clearance grow between fixed block and the slide bar in addition leads to fixed block self-sliding when the scraper prints, seriously influences the quality of printing.
SUMMERY OF THE UTILITY MODEL
The purpose of the utility model is to solve the shortcoming that exists among the prior art, through designing a novel printing machine scraper, the effectual problem of mentioning in avoiding appearing above-mentioned technical background.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a novel printing machine scraper, including the scraper body, scraper body top is fixed with the latch segment, screw on the latch segment has locking screw, both ends are fixed with tight piece about the scraper body, press from both sides and be equipped with the slide bar hole in the tight piece, slide bar hole size and slide bar shape adaptation, the slide bar adopts square pole, is equipped with the apron at tight piece of clamp, restriction slide bar lateral shifting, sliding fit has the scraper piece on the slide bar.
According to the further technical scheme, a scraper blade is clamped below the scraper body, and the included angle of the scraper blade and the scraper body is 60 degrees.
According to a further technical scheme, the scraper body is provided with scale marks.
According to the technical scheme, the number of the scraper blocks is two, the scraper blocks are provided with long bolts, the long bolts are in threaded fit with the supports inside the scraper blocks, and the buffer blocks are arranged below the supports.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses the slide bar adopts square pole, sliding fit has the scraper piece on the square pole, be equipped with the stay bolt on the scraper piece, stay bolt and the inside support screw-thread fit of scraper piece, the support below buffer block in addition, when adjusting the distance between two scraper pieces according to the scale mark on the scraper body and accomplishing, the stay bolt of screwing, the tight slide bar in stay bolt top this moment, the scraper piece position is firmly fixed in the assigned position promptly, can not be along with the increase of printing number of times, the distance between the scraper piece changes, the tin cream quantity has been practiced thrift, the scraper piece becomes the angle of 60 degrees installation with the scraper body, change the tin cream of scraping on the otter board when the scraper moves.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is the internal structure diagram of the scraper block of the present invention.
In the figure: the scraper comprises a locking block 1, a locking screw 2, a clamping block 3, a cover plate 4, a scraper block 5, a long bolt 5-1, a buffer block 5-2, a support 5-3, a sliding rod 6, a scraper blade 7 and a scraper body 8.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1, one of them novel printing machine scraper, including scraper body 8, 8 tops of scraper body are fixed with latch segment 1, screw on latch segment 1 and have locking screw 2, locking screw 2 and printing machine adaptation, both ends are fixed with tight piece 3 about scraper body 8, be equipped with the slide bar hole in the tight piece 3 of clamp, slide bar hole size and the adaptation of 6 shapes of slide bar, slide bar 6 adopts square pole, are equipped with apron 4 pressing from both sides tight piece 3, restrict 6 lateral shifting of slide bar, sliding fit has scraper block 5 on slide bar 6.
The utility model discloses in, scraper body 8 below is pressed from both sides tightly has scraper blade 7, scraper blade 7 becomes 60 degrees contained angles with scraper body 8.
The utility model discloses in, be equipped with the scale mark on the scraper body 8, the scraper piece 5 quick adjustment interval of being convenient for to adapt to PCB printing scope.
The utility model discloses in, scraper block 5 is equipped with two, be equipped with stay bolt 5-1 on the scraper block 5, stay bolt 5-1 and the inside support 5-3 screw-thread fit of scraper block 5, buffer block 5-2 is still gone up to support 5-3 below.
In conclusion, when in specific use, the distance between the two scraper blocks 5 is adjusted according to the printing range of the PCB, the slide bar 6 of the utility model adopts a square bar, the scraper block 5 is matched on the square bar in a sliding way, the scraper block 5 is provided with a long bolt 5-1, the long bolt 5-1 is matched with a support 5-3 in the scraper block 5 in a threaded way, a buffer block 5-2 is arranged below the support 5-3, when the distance between the two scraper blocks 5 is adjusted according to the scale marks on the scraper body, the long bolt 5-1 is screwed, the long bolt 5-1 tightly pushes the sliding rod at the moment, the scraper blocks 5 are firmly fixed at the specified positions, the distance between the scraper blocks 5 cannot be changed along with the increase of printing times, the using amount of tin paste is saved, the scraper blade 7 and the scraper body are installed at an angle of 60 degrees, and the tin paste on the screen plate can be more easily scraped during the operation of the scraper.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
