Description
Technical field
The present invention relates to surface mounting technology（SMT）Technical field, specially a kind of SMT printing machine mesh-plate structure.
Background technology
The printing machine being traditionally used on a printed-wiring board is bitten generally by steel mesh, and the steel of traditional web plate
Net needs to be fixed on the printer spacing before printing machine carries out presswork, and the quality of fixed effect largely can
The quality of printing, and the structural stability that existing printing machine is fixed to steel mesh is not good enough, enters especially by steel mesh
The printing machine of row bidrectional printing operation, less stable, steel mesh can be subject to more disturbance, not only easily makes printing quality not
Height, and because easy generation shake causes steel mesh and the damage of equipment itself in operation process；Meanwhile, in printing
After the end of job, need steel mesh is carried out, and the steel mesh washing and cleaning operation of printing machine web plate is much by dismantling steel mesh
Get off by cleaning equipment or be manually carried out, washing and cleaning operation relative time is long, high cost, and to mesh-plate structure and print
Brush machine itself easily produces and damages, and certainly also has some not need to disassemble steel mesh, but can directly on the printer
It is carried out the device of operation, but these devices are relatively simple, stability is not good, and simply steel mesh upper surface is entered
The cleaning of row cleaning brush, and for a lot of pressworks after, lead to the steel mesh back side still can contaminate more printed material, tin cream or
Red glue of person etc., front cleaning performance is also not good, makes next batch be printed workpiece and receives pollution and affect printing effect, thus
Impact product quality, in addition, the wire netting of steel mesh makes thickness be substantially uneven, equally can affect printing quality.
Content of the invention
It is an object of the invention to provide a kind of good stability, efficiency high, printing quality SMT that is good and being easy to bidrectional printing print
Brush machine mesh-plate structure.
The above-mentioned technical purpose of the present invention technical scheme is that：A kind of SMT printing machine web plate knot
Structure, including steel mesh fixing device and the steel mesh cleaning device being arranged in described steel mesh fixing device, described steel mesh fixing device
Including about be oppositely arranged and structure is identical and two groups of steel mesh detent mechanisms in mirror image shape, described steel mesh detent mechanism includes edge
The base flat board that fore-and-aft direction is extended, the steel mesh that described base flat board is provided with the rectangular shape extending along fore-and-aft direction leans on
By transverse slat, described steel mesh leans on and is provided with a row above transverse slat along fore-and-aft direction arrangement and to another group of steel mesh detent mechanism direction
The clamping action matrix extending, described clamping action matrix and described steel mesh lean on and are provided with for described clamping action base between transverse slat
The lifting clamping device of block lifting, the top of described clamping action matrix is fixed with the hinged axostylus axostyle extending along vertical direction,
The lower locating back that on described hinged axostylus axostyle, hinged oriented another group of steel mesh detent mechanism direction extends, the bottom of described lower locating back
Dynamic pressure flat board is installed, is connected with positioned at dynamic pressure flat board back to another group of steel mesh between described dynamic pressure flat board and described lower locating back
The rectification spring of detent mechanism side, described dynamic pressure flat board is just being provided with inside with electricity to another group of steel mesh detent mechanism side
The magnetic sheet of magnetic coil, described steel mesh cleaning device includes two sets of base flat boards being separately positioned on the two groups of steel mesh detent mechanisms in left and right
Go up the wiper mechanism being oppositely arranged in left and right and structure is identical, described wiper mechanism includes one and is fixed on base flat board upwards
The upper pilum extending and the lower pilum being oppositely arranged and extending downwardly with described upper pilum, described upper pilum are rotatably connected to and stretch
To the upper support rail directly over steel mesh, the bottom of described upper support rail is provided with the upper cleaning brush towards steel mesh, described under
The lower support rail stretching to immediately below steel mesh is rotatably connected on pilum, the top of described lower support rail is provided with towards steel mesh
Lower cleaning brush.
In technique scheme, steel mesh fixing device and steel mesh cleaning device obtain extraordinary fusion each other, whole
The symmetry of individual structure is good, and distribution of force is relatively reasonable, strong antijamming capability, is easy to the raising of printing quality, beneficial to two-way print
Brush, steel mesh fixing device is preferable to the fixed effect of the steel mesh left and right sides, meanwhile, larger trembling during presswork
The skew of dynamic or instantaneous position, interstructural mobility can preferably be depleted to most of energy, facilitate follow-up reset,
Reduce and steel mesh and equipment itself are damaged, by lifting the effect of clamping device, so that left and right clamping action matrix drives
Lower locating back lifting, when declining, so that the dynamic pressure flat board cooperation base flat board that lower locating back bottom is installed is clamped making
The steel mesh left and right sides is fixedly clamped by industry, and lifting clamping device may also connect to automatic control equipment, realizes Automated condtrol,
Different operations are coordinated to need, clamping action matrix can play preferable constitutional balance effect, lower locating back passes through jointed shaft
Bar and the hinged relationship of clamping action matrix, so that when very serious emergency, the dynamic role of structure obtains
With embodiment, reduce hard damage etc., the rectification spring that dynamic pressure flat board connects and the setting of magnetic sheet make steel mesh in left and right directions
Good fixing effect, the solenoid in magnetic sheet is not constantly in charged state, when not carrying out presswork, electricity
Magnetic coil does not charge, so not having magnetic, but and proceeds by presswork after steel mesh is fixing, now solenoid fills
Electricity is so that magnetic sheet all bands of the two groups of steel mesh detent mechanisms in left and right are magnetic and the setting of adjacent side is polarity identical, thus
The active force repelling each other can be produced, and action direction is left and right directions so that steel mesh is that generation is to the left and right in static fixation
The active force of stretching trend, has preferable tension effects, may further ensure that the stability in printing for the steel mesh, improves printing
Quality；The structural stability of steel mesh cleaning device is more preferably so that steel mesh need not disassemble after the print operation from printing machine
