Preferably, each dodges length and the wide length that is greater than respectively this components and parts region of dodging the printed circuit board (PCB) on groove and wide of groove, and be less than the length of whole printed circuit board (PCB) and wide, each degree of depth of dodging groove is greater than the maximum height that this dodges the components and parts of the printed circuit board (PCB) on groove.In design, dodge length and width and the Gao Shi of groove, should correspondingly arrange according to the structure of the printed circuit board (PCB) of its concrete carrying.Dodge the element area that groove should be able to accommodating this printed circuit board (PCB), and make the edge of this printed circuit board (PCB) be attached at this this dodge on groove, all electronic components in holding element region are all suspended in this and dodge in groove simultaneously.
Preferably, those are dodged in groove and all have rib near the groove of dodging that prints the lateral edge of support plate.
Preferably, the material of this printing apparatus is metal or epoxy resin.
A printing machine, comprises a controller, a display, a printing chamber and a printing guide rail, and its feature is, this printing apparatus also comprises that printing apparatus as above and inhales vacuum plant.
Preferably, the height sum of this printed base plate and this printing support plate is less than the distance of upper surface He this printing chamber upper surface of this printing guide rail.The design of above-mentioned size makes this printing apparatus to print guide rail by this to be delivered to easily in this printing chamber.
Positive progressive effect of the present invention is:
The invention provides a kind of printing apparatus.By this printing apparatus being arranged to the form of two connecting plates, and this printing support plate is assembled on this printed base plate and can realizes assembling, therefore easy to use.In addition, those dodge groove can protect the electronic devices and components on printed circuit board (PCB) preferably, has advantages of that stability is high.Those are dodged structural design that groove, those air vent holes, this vacuum chamber and this inlet scoop be connected successively and can make printed circuit board (PCB) closely be adsorbed in to dodge on groove, facilitated the fixing of printed circuit board (PCB).

Embodiment
Below in conjunction with accompanying drawing, provide preferred embodiment of the present invention, to describe technical scheme of the present invention in detail.
As Figure 1-4, the printing apparatus A of the present embodiment comprises a printing support plate 2, and printing support plate 2 is provided with a plurality ofly dodges groove 21 and a plurality ofly dodges with each the air vent hole 210 that groove 21 is communicated with.Dodge length and the wide length that is greater than respectively on printed circuit board (PCB) corresponding components and parts region and wide of groove 21, and be less than the length of described whole printed circuit board (PCB) and wide, the degree of depth of dodging groove 21 is greater than the maximum height of the components and parts in components and parts region corresponding on printed circuit board (PCB).Some grooves of dodging near printing support plate lateral edge have breach 22 at the lateral edge place of printing support plate.
As shown in Figure 3, printing apparatus A also comprise one with the printed base plate 1 that is fastenedly connected of printing support plate 2, printed base plate 1 is provided with a vacuum chamber 11 being communicated with air vent hole 210 and an inlet scoop 12 being communicated with vacuum chamber 11.Fig. 1-2 has provided printing support plate 2 and printed base plate 1 carries out fastening situation by several bolts 3.When fastening, screw 23 and the screw 13 on printed base plate 1 on printing support plate 2 first carry out contraposition, are undertaken fastening afterwards by bolt 3 and nut.After fastening, printing support plate 2 is positioned at the top of printed base plate 1.
The height sum of printed base plate 1 and printing support plate 2 is less than the upper surface of track and the distance of printing chamber upper surface of printing machine.The material of printing apparatus A can be metal or epoxy resin.
During use, dodging that each the components and parts region on printed circuit board (PCB) is matched with this components and parts region is after groove 21 aims at, and the back side of printed circuit board (PCB) is upwards positioned over the upper surface of printing support plate 2.
By printed base plate 1 and printing support plate 2 are threaded, make printing apparatus A have advantages of that stability is high and easy to use.In addition, printing support plate 2 is provided with a plurality of grooves 21 of dodging, and these are dodged groove 21 and have protected preferably the electronic devices and components on printed circuit board (PCB).The setting party of breach 22 printed circuit board (PCB) on printing support plate 2, place and take off from printing support plate 2.
The printing apparatus of the present embodiment and embodiment 1 has the identical part in many places, for example, vacuum chamber 41 and inlet scoop 42, these same sections repeat no more herein.As shown in Figure 6, and the difference of the present embodiment and embodiment 1 is only: printed base plate and printing support plate can also be fastenedly connected by several screws.Now, on printed base plate 4, not only there is the screw 43 of penetration type, can also be provided with the holding screw hole 44 of partly running through.In addition, the edge of printed base plate 4 can also arrange several steps 45.These steps 45 be arranged so that base plate is convenient when clamping is mobile.
The printing apparatus of the present embodiment and embodiment 1 has the identical part in many places, for example, screw 53, these same sections repeat no more herein.As shown in Figure 5, and the difference of the present embodiment and embodiment 1 is only: each groove 51 of dodging near printing support plate 5 lateral edge has rib 52 at the lateral edge place of printing support plate 5.In addition, some air vent holes are positioned on printing support plate 5, but not with dodge groove 51 and be communicated with.
Owing to dodging the lateral edge place of groove 51, have rib 52, the air-tightness of printing support plate 5 and printed circuit board (PCB) better and more firm.
The present embodiment also provides a kind of SMT printing machine, comprises a controller, a display, a printing chamber, a printing guide rail, a printing apparatus as above and a suction vacuum plant.This suction vacuum plant is connected with inlet scoop, for adsorbing the printed circuit board (PCB) being fixed on printing support plate.
