Embodiment
[0036] This embodiment provides an intelligent screw installation device, such as figure 1 As shown, it includes an interconnected signal input unit 10, a control system 20, and a hardware execution unit 30, wherein the hardware execution unit 30 includes an electric batch 302 and a multi-axis robot 301, which may be, but not limited to, the hardware execution unit 30 It also includes a screw conveying system 303 , a jig fixing device 304 , and a signal lamp 305 . The multi-axis robot 301 provides a running mechanism for assembly actions. The electric screwdriver 302 provides a running action device for screwing. The screw conveying system 303 provides screw arrangement, material distribution and feeding devices. The jig fixing device 304 is used to fix the product, preventing the curing process from being completed and taking out the product artificially. Signal lights 305 are used for indication of process status.
[0037] The signal input unit includes a pressure sensor...

The invention discloses intelligent screw installing equipment. The intelligent screw installing equipment comprises a signal input unit, a control system and a hardware execution unit which are connected with one another, wherein the hardware execution unit comprises an electric screwdriver and a multi-axis robot, the signal input unit comprises a pressure sensor, a position sensor and a torque sensor, the control system is used for controlling and adjusting the operation speed and the torsion of the electric screwdriver according to the signal information transmitted by the signal input unit, and judging whether a screw is tightly screwed to a product or not according to the control algorithm of pressure, the torsion and the position. By means of the technical scheme, the intelligent screw installing equipment can be adapted to the screws with different specifications, the utilization rate of the equipment is improved, moreover, damage to products caused by excessive pressure can beavoided, and the consistency of the products can be improved.
Description
technical field [0001] The invention relates to the field of mechanical equipment, in particular to an intelligent screw installation equipment and a control method thereof. Background technique [0002] In the assembly process of automotive electronics, threaded connection is an important assembly link. As automotive electronics has higher and higher requirements for screwed connection tightening assembly, the torque control method using traditional clutches can no longer meet the needs of precise torque control. In the field of electronics, the intelligent electric batch with real-time monitoring of torque is gradually introduced, and assembled on the motion control platform to become an automatic intelligent screw tightening equipment. In the process of screwing, a certain pressure needs to be applied. Screws with different tooth pitches and diameters require different pressures. The existing automatic intelligent screw tightening equipment generally uses springs to apply...
