SMT mounter placement rate

Often listen to engage in smt people talk about the placement rate, SMT placement machine in the purchase when the main consideration of its paste fitting accuracy and placement speed, in the actual use process, in order to effectively improve product quality, improve production efficiency, improve the SMT placement machine paste fitting rate is particularly important.

 SMT placement machine placement rate is refers to in a certain time device actual placement number and suction number of ratio, which total abandoned pieces number is refers to suction with error number, recognition error number, standing piece number, lost number, etc., and recognition error and divided device specification size error and device optical recognition error two kinds. smt placement machine whether small machine, medium machine, large machine, also whether medium speed machine, high speed machine, they are mainly by device storage and transportation Device, XY table, mount head and control system composition. The mount head is the core and the key component of the mount machine, the mount head generally has the fixed head and the rotating head, the fixed general multi-head arrangement, less than 2, more than 8, can take the pieces at the same time or alone, the rotating head and divided in the horizontal plane rotation and in the vertical plane rotation.

  SMT placement machine placement process: 1, device suction up suction nozzle suction up height switch 2, θI rotation (±90') 3, device optical identification 4, device posture detection θ2 rotation (±90') 5, placement device/suction nozzle height switch 6, θ3 rotation (±180'-θ) suction nozzle Origin detection ** product exclusion 7、Nozzle conversion 8、Nozzle number detection according to the mounter from pick-up.

The whole process of mounting, simply from the mounter side, in the correct setting nozzle pickup height, pickup bit nozzle centre and the relative position of the feeder case, the main factors affecting his [see the rate of mounting is in the pickup position, according to the mounter statistics production information intelligence, its impact accounts for more than 80% of the entire impact factors. And the cause has: on the one hand is the device storage device on the feeder, on the other hand is the suction nozzle, both of which the influence of the feeder accounted for about 60%, about 40% is due to the suction nozzle pollution caused by.
