The specific embodiment
The circuit board of electronic product generally all is to be substrate with pcb board (printed circuit board (PCB)), assigns electronic component thereon and forms.Pcb board need print soldering paste on the pad that the electronic component part is installed after having finished the copper cash installation work, then electronic component is attached on the pcb board, sends in the reflow ovens and welds.Full-automatic vision printing machine of the present invention, its effect are exactly to be tin cream in the pcb board printing of finishing the copper cash wiring.
See also Fig. 1 to Fig. 3, this full-automatic vision printing machine comprises an automatic lifting system (figure does not show), position adjustment platform 2, a lifting platform 3, a steel mesh system 4, an optical imaging system 5, a scraper 6 and a computer control system (figure does not show).
This automatic lifting system comprises a support platform 12, and the below of this support platform 12 is provided with devices such as a series of silk axle, electro-motor, and they support this support platform 12, and this support platform 12 is moved up and down.
The top that platform 2 is installed on this support platform 12 is adjusted in this position, and it comprises a workbench 20, three adjusting devices 22 and four legs 24.
This workbench 20 is one and has certain thickness flat metal plates, and it is provided with four sidewalls, and the right-hand member of the two ends, the left and right sides of its front side wall 200 and this right side wall (not label) is installed a fixed block 204 respectively, and this fixed block 204 is provided with a chute 208.
These three adjusting devices 22 are installed on this support platform 12, the left and right two ends that their corresponding these three fixed blocks 204 are separately positioned on these workbench 20 front side walls 200 with and the right side wall right-hand member near.
Each adjusting device 22 all comprises the terminal holder of a silk axle 220,222, head end holder 224, head 226, a stepper motor 228.
This end holder 222 and this head end holder 224 are installed on this support platform 12, and this head end holder 224 is installed on the positive inboard of this end holder 222.
These axle 220 outsides are provided with some external screw threads (not label), the end of this axle 220 wore should end holder 222 middle parts, its head end wore this head end holder 224 middle parts, and this axle 220 can rotate in this end holder 222 and head end holder 224.
This head 226 comprises a connecting plate 2260, it comprise a vertical intermediate plate 2261, one from this intermediate plate 2261 ora terminalis forward vertically the upper head plate that extends of bending 2263, one from 2261 times ora terminalis of this intermediate plate vertical bottom plate 2265 of extending of bending backward.
A hinge seat 2262 is installed on the upper head plate 2263 of this connecting plate 2260, the rear end of this hinge seat 2262 is provided with a forked articulated section 2264, connect a connecting rod 2266 with a bolt in this articulated section 2264, this connecting rod 2266 can be around this bolt left-right rotation flatly.The rear end of this connecting rod 2266 connects a slide block 2268, this slide block 2268 is fastened in the chute 208 of fixed block 204 of these workbench 20 correspondences, this slide block 2268 can slide in chute 208, is connected with each other with workbench 20 by making slide block 2268 and cooperating of chute 208 this head 226.
A slide block 2270 is installed in bottom plate 2265 belows of this connecting plate 2260, on this support platform 12 endways between holder 222 and the head end holder 224 to being provided with a fixed block 2272 by each slide block 2270, offer a chute 2274 on this fixed block 2272, this chute 2274 is parallel to this axle 220, these slide block 2270 correspondences are fastened in this chute 2274, and this slide block 2270 can slide along this chute 2274.
One of fixed installation is socketed in the silk braid 2276 outside the silk axle 220 on the intermediate plate 2261 of this connecting plate 2260, the inside of this silk braid 2276 is provided with some corresponding silk axle 220 externally threaded internal threads (figure does not show), and this axle 220 passes from this intermediate plate 2261 and silk braid 2276 middle parts.During 220 rotations of silk axle, its external screw thread cooperates with the mutual interlock of the internal thread of this silk braid 2276, because the fixed-site of silk axle 220 is constant, therefore this silk braid 2276 moves along the direction of this axle 220, also be towards moving with direction away from this workbench 20, the silk braid 2276 that should move drives this connecting plate 2260 and moves, and moves thereby drive whole head 226, and this slide block 2270 slides in chute 2274 simultaneously.Being connected in two heads 226 of two adjusting devices 22 at these two ends, workbench 20 front side walls, 200 left and right sides can be forward or move backward, and the head 226 that is connected in the adjusting device 22 of these workbench 20 right side wall right-hand members can left or move right.
This stepper motor 228 is installed in the side of this end holder 222, with a belt rotating shaft 2282 of this stepper motor 228 and silk axle 220 ends that stretch out outside this end holder 222 is coupled together.When this stepper motor 228 rotated, this belt drove this axle 220 rotations.
