Background technology
In SMT production technology, typography is particularly important, particularly, along with the development that becomes more meticulous of electronic devices and components, requires also more and more stricter to SMT typography.The quality that tin cream or red glue apply directly has influence on the welding quality of electronic devices and components.Doctor blade device is one of important tool of screen painting, and its effect is at the uniform velocity to move by scraper level, and tin cream or red glue are bitten on the corresponding position of PCB by the mesh on half tone.
Traditional SMT printing press scraper device is fixed dimension, wing surfacing, the width that wing is scraped is a fixing width, the width that can not scrape wing regulates, a kind of doctor blade device of specification can only meet the PCB corresponding with its width, in the time that scraper moves, tin cream or red glue can overflow from wing two ends, cause tin cream or red glue to apply inhomogeneous, and do not have tin cream in moving process or the stirring action of red glue.
Summary of the invention
Its object of the present invention is just to provide a kind of intelligent printing press scraper device; solve the problem that tin cream or red glue apply inhomogeneous, to meet different in width PCB printing needs; there is feature easy and simple to handle, adjustable position; and can protect half tone not damage; extend the service life of scraper and half tone; increase lubricity, toughness and the agitating function of wing, improved the mobility of tin cream or red glue, promoted press quality.
The technical scheme that realizes above-mentioned purpose and take, comprises doctor blade holder, wing, and described wing is provided with and protects tin sheet, and protecting tin sheet is elastomeric material, is the two-piece type structure that centre separates, and protects tin sheet and is fixed on doctor blade holder through fixed block, guide rod; Described doctor blade holder is fixed on printing machine through doctor blade device fixed screw; Described wing is fixed on doctor blade holder through wing fixed screw and wing strap.
Compared with prior art the present invention has the following advantages.
1, this device can regulate the position of protecting tin sheet according to the width of PCB, a set of doctor blade device just can meet the printing needs of different in width PCB, regulate for convenient, this device has designed rule on doctor blade holder, and adopted the fixed block of spring ripple pearl to fix the position of protecting tin sheet, easy and simple to handle;
2, this device has adopted softness good, the elastomeric material of acid and alkali-resistance has designed the split type tin sheet that protects, good flexibility, no matter split type design is that the round movement of scraper can be protected tin cream or red glue in printing zone effectively, good flexibility also can meet scraper simultaneously and carry out the requirement of angle adjustment because of printing needs, and can protect half tone not damage, and extends scraper and half tone service life;
3, this device has adopted stainless steel SUS201 material, and on its edge of a knife, moves 1.5 millimeters of groove matrixes of locating to design Different Rule, carry out the wing of electroplating processes, increase lubricity, toughness and the agitating function of wing, improved the mobility of tin cream or red glue, promoted press quality.

Detailed description of the invention
Comprise doctor blade holder 1, wing 6, as shown in Fig. 1,2,3,4,5, described wing 6 is provided with and protects tin sheet 2, protects tin sheet 2 for elastomeric material, is the two-piece type structure that centre separates, and protects tin sheet 2 to be fixed on doctor blade holder 1 through fixed block 3, guide rod 5; Described doctor blade holder 1 is fixed on printing machine through doctor blade device fixed screw 7; Described wing 6 is fixed on doctor blade holder 1 through wing fixed screw 8 and wing strap 9.
Described doctor blade holder 1 is provided with rule 4.
Described wing 6 adopts stainless steel SUS201 material, and described wing 6 moves 1.5 millimeters of places and is provided with groove matrix on its edge of a knife.
Embodiment
With reference to accompanying drawing 1-5, comprise doctor blade holder 1, protect tin sheet 2, fixed block 3, rule 4, guide rod 5, wing 6, doctor blade device fixed screw 7, wing fixed screw 8, wing strap 9, the described tin sheet 2 that protects adopts flexibility good, the elastomeric material of antiacid alkali, in the middle of being designed to, separately, tin all can be protected in wing 6 both sides.By guide rod 5, according to the width of PCB, with reference to rule 4, utilize fixed block 3 to be fixed on doctor blade holder 1; Described doctor blade holder 1 is to be installed on printing machine by doctor blade device fixed screw 7; Described wing 6 is by wing fixed screw 8, and wing strap 9 is installed on doctor blade holder 1.
This device is arranged on printer device frame, printing scraper sheet 6 is according to the actual requirement adjustable angle of PCB, according to the width of PCB, reference mark chi 4 is adjusted the position of protecting tin sheet 2, and fix position with fixed block 3, drive this device to move on screen frame by motor, so that described printing scraper sheet 6 scrapes tin cream or red glue; When work, tin cream or red glue are in the time that doctor blade holder 1 moves, and by the perforate of half tone, the PCB that bites is upper, reaches coating effect, completes PCB print solder paste or red glue work.
Now described rule 4, in the time that the position of tin sheet 2 is protected in adjusting, convenient and swift.Protect the design that tin sheet fixed block 3 utilizes spring ripple pearl, easy and simple to handle, and good fixing effect.It is to utilize spring to withstand ripple pearl, plays fixation.In the time of mobile fixed block 3, what contact guide rod 5 is ripple pearl, because ripple pearl is spherical, mobile very smooth and easy.
The described tin sheet 2 that protects, is arranged on the two ends of printing scraper sheet 6, adopts soft belt elasticity, acid and alkali-resistance elastomeric material, separation design.Elasticity, acid and alkali-resistance elastomeric material can effective guarantee tin cream or red glue in mobile printing process, can overflow printing region, and can not damage half tone because of frequent mobile printing.Separation design, protects tin sheet 2 and is stuck on wing 6, comes and goes when mobile at wing, all tin cream to be printed or red glue can protect in printing zone, and played stirring action in each mobile process of printing, and increases its current lubrication.Can improve the effect of biting of printing, guarantee printing quality.
Originally protect tin sheet soft belt elasticity in the time that wing is adjusted angle, can not cause because of Angulation changes wing by padded, cause situation about cannot print.
Described printing scraper sheet 6 adopts stainless steel SUS201 material, carries out electroplating processes, increases the lubricity of the edge of a knife, and on its edge of a knife, moves 1.5 millimeters of groove matrixes of locating to design Different Rule.Stainless steel SUS201 material has acidproof, alkaline-resisting, good toughness.Make wing with SUS201 material, its acidproof, alkaline-resisting characteristic can effective guarantee tin cream or the chemical analysis of red glue in printing process stable.Its good toughness can guarantee that wing is in the time of mobile printing, and wing and half tone close contact, ensure that in printing process, tin cream or red glue can not remain on half tone, guarantee the good effect of biting.Also can not cause half tone wearing and tearing because of friction simultaneously.Wing 6 is sprayed to the electroplating processes of Teflon.On its edge of a knife, move 1.5 millimeters of groove matrixes of locating to design Different Rule.Can effectively increase the lubricity of the edge of a knife, tin cream or red glue, in printing process, during through groove matrix, can play good stirring action, thereby increase its mobility, and good lubricity and mobility are the guarantees of press quality.
