Abstract
The invention relates to the technical field of PCB (printed circuit board) production equipment, in particular to an automatic detection mechanism for a zero contact point of a scraper of a vision printer with a steel mesh, which comprises the scraper, the steel mesh and a detection unit. The scraper is mounted on a lifting suspension of the printer, the steel mesh is positioned below the scraper, the detection unit is used for sending out signals when the scraper is in zero contact with the steel mesh, and the detection unit transmits the signals to the control system of the vision printer. The contact point of the scraper with the steel mesh is determined by the detection unit instead of naked eyes, operation is simpler and more convenient, labor intensity is low, and pointing is more accurate and easier to master, so that printing quality and efficiency can be promoted. Further, operation ratio and operability of equipment are improved, the automatic detection mechanism is accordant to industrial utilization, and production efficiency is improved.
Description
Technical field
The present invention relates to pcb board production equipment technical field, especially relate to and be used for the vision printer that pcb board is produced.
Background technology
SMT technology (surface installation technique or surface mounting technology) is because of it has the packing density height, the electronic product volume is little, in light weight; The volume and weight of surface mount elements has only advantages such as about 1/10 of traditional inserting element, is applied to more and more widely in electronic printing circuit board (PCB) industry.After the general employing SMT, electronic product volume-diminished 40% ~ 60%, weight saving 60% ~ 80%.When SMT paste solder printing pcb board, wherein one technology is to push printing to tin cream with scraper, thereby is transferred to tin cream on the pcb board from steel mesh.During work, scraper contact steel mesh upper surface drives straight line by actuating unit and moves, and realizes scraping from the Printing Zone of steel mesh, to tin cream extruding printing.In the prior art, scraper and steel mesh contact point are to be confirmed by operator's naked eyes, influenced greatly by human factor, so that actual contact point often occurs and differ greatly with the zero point that contacts of standard, cause scraper to print overweight or kick the beam, and influence printing quality.
The applicant is because the disappearance and the inconvenience of above-mentioned convention vision printer; The spirit of adhering to the research innovation, keeping on improving; Utilize its professional eye and professional knowledge, the scraper that works out a kind of vision printer of accords with industrial utilization contacts automatic detecting machine structure at zero point with steel mesh.
Summary of the invention
The objective of the invention is to overcome the defective of prior art, provide a kind of simple in structure, be prone to management and control, confirm scraper and steel mesh contact point with electronic technology, get a little more accurately the scraper of vision printer contacts automatic detecting machine structure at zero point with steel mesh.
For achieving the above object, the present invention adopts following technical scheme:
The scraper of vision printer contacts automatic detecting machine structure at zero point with steel mesh; Include the scraper on the up-down suspension frame that is installed in printing machine and be positioned at the steel mesh of scraper below; And also including the detecting unit that sends signal at scraper when steel mesh contacts zero point, this detecting unit passes to signal the control system of vision printer.
In the such scheme; Said detecting unit is a signaling switch; Include supporting optoelectronic switch transmitter and optoelectronic switch receiver, between optoelectronic switch transmitter and optoelectronic switch receiver, be provided with one can intercept the line of departure block piece, block piece and scraper interlock.
In the such scheme, said detecting unit can also be an inductor, be attached to scraper or with the parts of scraper interlock on; Displacement on the body, deflection, stressed and electric current etc. are depended in inductor induction.
With prior art contrast, the present invention confirms that through detecting unit scraper and steel mesh contact point replace naked eyes and confirm that its operation is easier, and labour intensity is low, and get a little more accurate, easier management and control, thereby lifting printing quality and efficient.
An advantage more of the present invention is simple in structure, and is scientific and reasonable, makes easily, and cost of investment is low, and is easy and simple to handle, promoted the operation ratio and the operability of equipment greatly, and accords with industrial utilization is enhanced productivity.
Description of drawings:
Accompanying drawing 1 is an one of which example structure sketch map of the present invention;
Accompanying drawing 2 is the action sketch map of Fig. 1 embodiment.
The specific embodiment:
Below in conjunction with accompanying drawing the present invention is further specified:
Consult shown in Figure 1ly, be one of which example structure sketch map of the present invention; The scraper of the relevant vision printer of the present invention contacts automatic detecting machine structure at zero point with steel mesh; Include the scraper 1 on the up-down suspension frame that is installed in printing machine and be positioned at the steel mesh 2 of scraper below; Also include the detecting unit 3 that sends signal at scraper 1 when steel mesh contacts for 2 zero points, this detecting unit 3 passes to signal the control system of vision printer.The control system of vision printer adopts the technology of PLC or single-chip microcomputer, and this technology is given unnecessary details at this for the mature technology of existing vision printer no longer one by one.
Embodiment:
Fig. 1, shown in 2, in the present embodiment, said detecting unit 3 is signaling switches; Include supporting optoelectronic switch transmitter 31 and optoelectronic switch receiver 32, between optoelectronic switch transmitter 31 and optoelectronic switch receiver 32, be provided with one can intercept the line of departure block piece 4, block piece 4 and scraper 1 interlock; Among the figure, block piece 4 is the lamellar body of bending, and an end is fixed on the mount pad of scraper 1; Be fixed with one between mount pad and the scraper 1, thereby realize interlock.The other end activity of block piece 4 is plugged in the passage between optoelectronic switch transmitter 31 and the optoelectronic switch receiver 32, realizes intercepting the line of departure.Shown in Figure 2, when scraper 1 presses down towards steel mesh 2 directions under up-down suspension frame drives, and when touching steel mesh 2; Scraper 1 receives steel mesh 2 reactions and the resilience displacement is arranged; At this moment the rising displacements take place in the block piece 4 with scraper 1 interlock, and promptly block piece 4 is withdrawn from the blocking of the line of departure, so that the ray that optoelectronic switch transmitter 31 sends is received by optoelectronic switch receiver 32; Reach switch connection; Output switching signal is given the control system of vision printer, and the control system of vision printer can obtain the zero point that contacts of scraper 1 and steel mesh 2, controls scraper 1 thus and works.Operate easylier, labour intensity is low, and get a little more accurate, management and control more easily, thus promote printing quality and efficient.
Said detecting unit 3 can also be the inductor pattern except the pattern of the foregoing description, and be attached to scraper 1 or with the parts of scraper interlock on.Depend on variations such as displacement on the body, deflection, stressed and electric current through inductor induction; Output signal to the control system of vision printer thus; Same, the control system of vision printer can obtain the zero point that contacts of scraper 1 and steel mesh 2, controls scraper 1 thus and works.
It is convenient, accurate that the present invention not only gets zero point, and can guarantee scraper 1 and steel mesh 2 full contacts, when promoting printing quality and efficient, also effectively protects scraper 1, prolongs its service life.
Certainly, more than diagram is merely preferred embodiment of the present invention, is not to limit practical range of the present invention with this, so every principle according to the present invention is done the equivalence variation or modified, and all should be covered by in protection scope of the present invention.
