controlling the servo driver to start;
after the servo driver is started, controlling a laser sensor to acquire a first product characteristic of the rear barrel insert;
controlling a positioning pin sensor to acquire a second product characteristic of the rear barrel insert;
and if the first product characteristic and the second product characteristic both meet the preset characteristic requirement, determining that the servo driver meets the stop condition.
6. The apparatus positioning method of claim 5, wherein after controlling a locating pin sensor to acquire a second product feature of the back barrel insert, the apparatus positioning method further comprises:
if the first product characteristic and/or the second product characteristic do not meet the preset characteristic requirement, controlling a preset robot to wait above the target device point;
and taking back the rear barrel insert, and starting to perform visual detection on the rear barrel insert again so as to analyze the product characteristics of the rear barrel insert.
7. The apparatus positioning method according to claim 5, wherein the preset robot and the robot jig are mounted on the injection molding machine tool, and the injection molding machine tool is built with a product conveying line, a vision apparatus, a laser sensor, and a positioning pin sensor.
8. The apparatus positioning method according to claim 7, wherein the injection molding machine is of the type of a hydraulic injection molding machine.
9. An injection molding machine based equipment positioning system, comprising:
the injection molding machine comprises an injection molding machine tool and a preset robot, wherein the preset robot is arranged at the upper end of the machine tool;
the vision device is associated with the clamp of the preset robot and is used for acquiring an appearance image of a rear barrel insert of the washing equipment and an image of a positioning hole point corresponding to the rear barrel insert;
a positioning controller configured to perform the injection molding machine based device positioning method of any one of claims 1 to 8 via execution of executable instructions.
10. A computer-readable storage medium, comprising a stored computer program, wherein the computer program, when executed, controls an apparatus in which the computer-readable storage medium is located to perform the method for positioning an injection molding machine-based apparatus according to any one of claims 1 to 8.
