Abstract
The invention relates to a fully-automatic cutting, detecting and hole-repairing method applied to an SMT (surface mounting technology) laser template. The method is characterized by comprising the following steps of 1, loading a machined steel plate on machine equipment, and calling a machining data file for cutting and machining, wherein the machining area is a rectangular range from (X1, Y1) to (X2, Y2); 2, when the coordinate difference between the cutting position of a cutting nozzle and the central position of a detecting line section of the linear array laser sensor is (delta X, delta Y), scanning in the rectangular range from (X1-delta X, Y1-delta Y) to (X2-delta X, Y2-delta Y); 3, judging the position and the area shape of an opening according to the existence of data because no data exists at the opening; 4, comparing an identified pattern with the original data pattern through simulation identifying software of a control system, and judging whether the SMT template steel plate has the defect that holes are not enough or excessive or not; and 5, if qualified, ending machining, if the holes are not enough, acquiring the coordinates of the opening through a detecting result and automatically repairing the holes again, and if the holes are excessive, the excessive holes are directly discarded.
Description
Technical field
The present invention relates to SMT laser cutting steel disc field, be specifically related to a kind of equipment and method of using cutting and noncontact linear array laser sensor equipment integrating SMT laser cutting template steel disc to be carried out automatic cutting processing, the few empty detection of porous and perforations adding.
Background technology
At present SMT template laser cutting technique is widely adopted, use the high-speed cutting of moving beam formula finish the template cutting after, there is the few hole defect of porous in template toward contact.What generally adopt now all is manual detection, and at first the steel disc that cutting is finished and the screen frame that stretches tight take off from cutting equipment, steel disc are taken off on the monitor station that is placed into end light from the screen frame that stretches tight again.The testing staff is printed the datagraphic file with translucent template, overlap then on the steel disc, examines to check out whether have the few hole defect of porous according to figure and printing opacity situation testing staff needs with ocular vision.The placement of template positive and negative in the process that detects, direction and contraposition all around all will rely on manually-operated to handle, and all depend on testing staff individual quality on efficient and accuracy.Many for hole number, omitting appears in template that density is big easily, and human factor becomes the key factor that influences reliability.Need to repeat to call data file, printing in the testing process, not only increase cost of labor but also increased paper consumption.If detect finding has few hole situation, also need again the steel disc clamping is installed to the screen frame that stretches tight once more and carry out contraposition on the cutting machine and mend and carve the hole.This work has also increased artificial and cost greatly for production line when increasing product quality reliability.
Summary of the invention
The present invention proposes the method that a kind of SMT of being used for laser template automatically cuts detection and perforations adding, use cutting and noncontact linear array laser sensor equipment integrating carry out the equipment and the method for automatic cutting processing, the few empty detection of porous and perforations adding to SMT laser cutting template steel disc, can improve and finish Laser cutting, detection and perforations adding work automatically, can enhance productivity, save production cost greatly.
At above problem, the present invention proposes following scheme:
A kind of cutting and noncontact linear array laser sensor equipment integrating comprise the granite platform, the screen frame clamping workpiece platform that stretches tight, and it is characterized in that equipment also comprises a type trave lling girder, processing and detects Z axle module and control system.
Preferably, described door type trave lling girder comprises X-axis motion assembly and Y-axis motion assembly.
Preferably, described processing and detection Z shaft assembly comprise laser cutting head, linear array laser sensor and Z axle motion assembly, and it be the line segment distance of D that this laser cutting head can detect length at the Y direction one-off scanning.
A kind of full-automatic cutting detection of SMT laser template and method of perforations adding of being used for is characterized in that, comprises step: 1. processed steel disc is loaded onto machinery equipment, call the process data file and carry out cutting processing, machining area is that (X1 is Y1) to (X2, rectangular extent Y2); 2. cutting head cutting position and linear array laser sensor detection line segment center position coordinates difference is (△ X, △ Y), then arrives (X2-△ X, Y2-△ Y) rectangular extent interscan at (X1-△ X, Y1-△ Y); 3. owing to not having data, by position and the area shape that can judge opening to having or not of data in the position that opening is arranged; 4. figure after will discerning by the simulation identification software of control system and former datagraphic relatively judge whether SMT template steel disc exists the few hole defect of porous; If 5. qualified then finish processing, if would find few hole then can obtain the coordinate and the perforations adding reparation again automatically of opening, if porous is directly scrapped by testing result.
Preferably, this method further comprises: multiple scanning perforations adding zone was detected after the perforations adding reparation was finished.
The present invention proposes the method that a kind of SMT of being used for laser template automatically cuts detection and perforations adding, use cutting and noncontact linear array laser sensor equipment integrating carry out the equipment and the method for automatic cutting processing, the few empty detection of porous and perforations adding to SMT laser cutting template steel disc, can improve and finish Laser cutting, detection and perforations adding work automatically, can enhance productivity, save production cost greatly.
