Brief description of the drawings
Fig. 1 schematically shows the structure diagram of the present invention.
Embodiment
The embodiment of the present invention is described in detail below in conjunction with attached drawing, but the present invention can be defined by the claims
Implement with the multitude of different ways of covering.
The present invention provides a kind of tin soldering machine control system, including electric cylinders, circuit board clamp, welding gun manipulator, camera,
Image processing apparatus, station detection unit and controller, the circuit board clamp are installed on the output terminal of electric cylinders；
The controller receives the PCB figures for the circuit board being clamped on the circuit board clamp, and the PCB is schemed to send
Give described image processing unit；Described image processing unit handles the PCB figures, and is welded from the PCB figures
The shape, size and coordinate information of each solder joint are packaged into by point number, shape, size and coordinate, described image processing unit
Solder joint data packet is sent to the controller；
The controller is detecting that the fixture and circuit board thereon reach welding by the station detection unit
After station, the camera is controlled to obtain the image of the welding surface of the circuit board, and described image is sent to described image
Processing unit；
Described image processing unit identifies the electronics to be welded being sticked in advance on the circuit board according to described image
Element and its corresponding solder joint；The controller finds from the solder joint data packet corresponding with the solder joint according to the solder joint
Solder joint shape, size and coordinate, and generate according to the solder joint shape and size the motion path of the welding gun manipulator；
The welding gun manipulator is moved at solder joint to be welded by the controller according to the coordinate, then according to institute
State solder joint shape and control the fortune rifle angle of the welding gun manipulator and by the movement path.
By adopting the above-described technical solution, the present invention can be automatic raw according to the size and shape of solder joint (or pad)
Into the welding motion path for being adapted to the solder joint, so as to will be welded completely around solder joint, prevent in the prior art around solder joint
Scolding tin electronic component rise foot around the problem of can not being uniformly distributed, make the contact impedance between pin and circuit board more equal
It is even, so as to ensure the stability of signal transmission, avoid control logic caused by distorted signals chaotic.
Preferably, the controller is after the completion of welding of the welding gun manipulator along the motion path, described in startup
