Description

Technical Field

[0002] In the fields of electrical engineering, building decoration, and industrial automation, wire ducts are widely used for laying electrical wires and cables, playing a role in protecting and organizing the lines. However, in the prior art, the cutting of wire ducts usually relies on manual operation. Operators need to cut the wire ducts section by section according to actual requirements using cutting tools such as hacksaws and cutting machines, and during the cutting process, they must continuously adjust the cutting length manually to ensure that the cut wire ducts meet the required specifications.

[0003] This manual cutting method of wire ducts has many drawbacks. Firstly, it is difficult to guarantee the accuracy of manual cutting, and there may be errors in the length of the cut wire ducts, resulting in the subsequent assembly work being unable to proceed smoothly, and even requiring re-cutting, wasting time and materials. Secondly, the manual cutting efficiency is low. Especially when facing the cutting tasks of a large number of wire ducts with different specifications, operators need to repeatedly measure and adjust the cutting length, consuming a large amount of time and energy. In addition, there are certain safety hazards during the manual cutting process, and operators are prone to accidental injuries when using cutting tools.

The pressing component presses the wire duct to be processed in the bearing groove, and then the cutting component performs cutting; J. The wire duct that is cut off is the wire duct that needs to be cut; K. Repeat steps H to J until the wire duct preparation task of one specification is completed; Among them, the pushing stroke of the second photoelectric sensing switch and the first pushing component in step H determines the length of the remaining material of the wire groove in the bearing groove; when the remaining material length is greater than the required cutting length and the cutting task of the wire groove of the next specification has been completed, the remaining material retraction mode is triggered; in the remaining material retraction mode, the second paddle of the remaining material retraction mechanism is driven by the third lifting cylinder and the second linear module to retract the remaining material; at the same time, the feeding mechanism moves to the corresponding receiving groove and docks with the feeding port of the receiving groove; then the first pushing component is driven by the first lifting cylinder and the second driving motor to retract the remaining material to the feeding mechanism; the feeding mechanism moves with the remaining material to the feeding port of the preparation bin of the corresponding specification; then, under the action of the third pushing component, the remaining material is pushed into the feeding channel of the preparation bin; When the remaining material length determined by the second photoelectric sensor switch and the pushing stroke of the first pushing assembly is less than the required cutting length, the waste removal mode is triggered; in the waste removal mode, the first unloading channel opens the waste material drop opening; in the waste removal mode, the first pushing assembly pushes the remaining material in the bearing groove toward the drop end and away from the base, and drops it into the waste turnover box; S3. Complete the cutting of wire ducts of various specifications in the wire duct preparation task in sequence according to step S2.

9. The material preparation method according to claim 8, characterized in that: The automatic preparation system for wire ducts for electrical cabinet assembly also includes a distribution mechanism; the distribution mechanism includes a turntable that rotates under the drive of a third drive device; the turntable is provided with preparation slots corresponding to multiple wire duct specifications; the turntable is arranged at the sliding end of the first unloading channel to guide the processed wire ducts to slide down; When executing step A or step B or step C, the allocating mechanism, driven by the third driving device, rotates the preparation groove on the turntable corresponding to the specification of the next cutting groove to the sliding end of the first unloading channel.

10. The material preparation method according to claim 8, characterized in that: The automatic wire duct preparation system for electrical cabinet assembly further comprises a remote communication module; the automatic wire duct preparation system for electrical cabinet assembly is used to receive wire duct preparation tasks via the remote communication module.
