State.
Laser marking machine 50 of the present utility model uses CO2 laser marking machines.
The course of work of the utility model laser marking device:
Initial position, the material containing platform 12 of pcb board feeding device 10 is below, and the pcb board for treating mark is overlayed into PCB
On the material containing platform 12 of plate feeding device 10, the first push pedal 42 of apparatus for temporary storage 40 and the second push pedal 61 of stop gauge 60 are expected
In the position close to material conveyer lateral wall 32, the striker plate 62 of stop gauge 60 is in blocking position, blanking device 70
Material containing platform is in top;Equipment starts, and the sucker 23 of pcb board feeding device 20 draws a PCB from pcb board feeding device 10
Plate 1 is moved on the conveyer belt 31 of material conveyer 30, when pcb board 1 is sent to material apparatus for temporary storage 40, the duplex of apparatus for temporary storage 40
Cylinder 41 controls the first push pedal 42 to be moved to the direction of madial wall 33, make pcb board 1 be clamped in the first push pedal 42 and madial wall 33 it
Between, realize the first time positioning of pcb board;Pcb board is continued to forward after the completion of positioning for the first time by conveyer belt 31;Work as pcb board
Front end stop motion when encountering the striker plate 62 of stop gauge 60, the second push pedal 61 of stop gauge 60 is to the direction of madial wall 33
It is mobile, pcb board is clamped between the second push pedal 61 and madial wall 33, realize second of positioning of pcb board;Pcb board is set
After position, laser marking machine 50 carries out mark to pcb board;Mark action is completed, and the striker plate 62 of stop gauge 60 rises to solve
Except the stop to PCB, when pcb board leaves stop gauge 60 completely, striker plate 62 returns to blocked state and waits next PCB
Plate;Pcb board continues to move ahead until from roller 36 time by flowing on blanking device 70, mark of the completion to pcb board.
In said process, when previous pcb board leaves material working area (region residing for material apparatus for temporary storage 40), pcb board feeding dress
Put 20 taken at once from pcb board feeding device 10 next pcb board via conveyer belt 31 be sent to material working area kept in
(pcb board is clamped between the second push pedal 61 and madial wall 33);When previous pcb board leaves stop gauge 60, the second push pedal
Clamping of 61 releases to latter pcb board makes it to flow to stop gauge 60 from apparatus for temporary storage 40.The setting of apparatus for temporary storage 40, one
Aspect can improve the operating efficiency of equipment, and on the other hand pcb board can be positioned in advance, be that follow-up mark improves essence
Degree.
