Description

Technical Field

[0001] The invention relates to a matching device in electric cabinet assembly, in particular to an automatic wire trough preparation system and a preparation method for electric cabinet assembly. Background Art

[0002] In fields such as electrical engineering, building renovation, and industrial automation, cable trunking is widely used to lay wires and cables, protecting and organizing them. However, in existing technologies, cutting cable trunking is often done manually. Operators use cutting tools such as hacksaws and cutters to cut the trunking into sections according to actual needs. During the cutting process, the cutting length must be manually adjusted to ensure that the cut trunking meets the required specifications.

[0003] This manual method of cutting cable ducts has numerous drawbacks. First, manual cutting accuracy is difficult to guarantee, and the cut cable duct length may be inaccurate, preventing subsequent assembly work from proceeding smoothly or even requiring re-cutting, wasting time and materials. Second, manual cutting is inefficient, especially when faced with the task of cutting a large number of cable ducts of varying specifications. Operators need to repeatedly measure and adjust the cutting length, consuming a significant amount of time and effort. Furthermore, manual cutting presents certain safety risks, and operators are prone to accidental injury while using cutting tools.

[0004] With the continuous development of industrial automation technology, the demand for improving production efficiency, reducing labor costs, and enhancing processing accuracy is becoming increasingly urgent. Consequently, some automated wire trough cutting devices have emerged. However, these existing automated wire trough cutting devices require operators to manually load and collect materials throughout the entire operation process.

[0027] S2. Select a specification of wire duct to be cut according to the wire duct preparation task; cutting is carried out according to the following steps:

[0028] A. According to the specifications of the wire duct to be cut, the lifting mechanism on the corresponding preparation bin will start lifting. The wire duct to be processed will slide from the feed channel to the lifting platform and be lifted upward by the lifting cylinder. As the lifting mechanism continues to lift, the wire duct will rise from the bottom lifting mechanism to the top lifting mechanism and be at the discharge port of the preparation bin.

[0029] B. The XY-axis linear module of the feeding mechanism drives the supporting platform to dock with the discharge port of the material preparation bin in step A.

When the wire trough to be processed is completely pushed into the loading tank, the feeding mechanism returns to the wire trough preparation bin to prepare for the next feeding; when the feeding mechanism leaves, the first paddle on the first pushing assembly descends under the drive of the first lifting cylinder, and then, driven by the second driving motor, enters the loading tank from the feeding port of the loading tank and pushes the wire trough to be processed in the loading tank toward the cutting device;

[0035] H. After the first pushing assembly pushes the wire groove to be processed in the bearing groove through the cutting device and is sensed by the first photoelectric sensor switch, the first pushing assembly stops pushing;

[0036] I. The pressing component presses the wire duct to be processed in the bearing groove, and then the cutting component cuts it;

[0037] J. The wire duct that is cut off is the wire duct that needs to be cut;

[0038] K. Repeat steps H to J until the wire duct preparation task for one specification is completed;

[0039] Among them, the pushing stroke of the second photoelectric sensor switch and the first pushing assembly in step H determines the remaining material length of the wire trough in the carrying slot; when the remaining material length is greater than the required cutting length and the cutting task of the wire trough of the current 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 slot and docks with the feed port of the receiving slot; then the first pushing assembly is driven by the first lifting cylinder and the second drive 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 assembly, the remaining material is pushed into the feed channel of the preparation bin;

[0040] 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 drop opening; in the waste removal mode, the first pushing assembly pushes the remaining material in the carrying trough toward the drop end and away from the base, and drops it into the waste turnover box;

[0041] S3. Complete the cutting of various specifications of the wire ducts in the wire duct preparation task in sequence according to step S2.

[0042] At the same time, when executing step A or step B or step C, the distribution mechanism is driven by the third driving device to rotate the preparation trough on the turntable corresponding to the specification of the current cutting line trough to the sliding end of the first unloading channel.

[0043] Furthermore, the automatic wire duct preparation system for electrical cabinet assembly further includes 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.

[0044] The present invention has positive effects: (1) The present invention can automatically calculate the length and quantity of wire ducts of different specifications required according to the assembly task, and then automatically generate cutting and material preparation tasks, and automatically perform cutting and material preparation. It has a high degree of automation and can prepare materials in advance according to the production plan, making it convenient for assemblers to directly carry out assembly work after work, thereby greatly improving assembly efficiency.

[0045] (2) The cutting device of the present invention uses a saw blade to cut the wire groove. When the saw blade cuts the wire groove, the wire groove cutting accuracy is high and the cutting speed is fast. The wire groove is not easy to deform or break. At the same time, large diameter wire grooves can also be easily cut off.

[0046] (3) The bearing groove on the base of the present invention allows the wire groove to be processed to be inserted with the groove teeth facing downward, which provides favorable conditions for subsequent pressing and cutting. The wire groove is not easy to move during the cutting process, thereby further improving the cutting accuracy and incision flatness.

[0047] (4) The preparation bin of the present invention can realize the automatic lifting of the wire trough by cooperating with the lifting mechanism and the lifting mechanism. In combination with the second pushing assembly, the automatic discharge function of the preparation bin is realized. In combination with the feeding function of the feeding mechanism, the automatic loading function of the wire trough to be processed is realized. At the same time, due to the automated control, the feeding mechanism can transport wire troughs of various specifications according to the wire trough preparation task. The high degree of automation can completely replace manual loading and is not easy to make mistakes.

[0048] (5) The present invention determines the length of the residual material by the second photoelectric sensor switch and the pushing stroke of the first pushing assembly, and thereby triggers the residual material return mode or the waste material removal mode, thereby realizing a more humane automatic unloading function.

[0049] (6) The present invention can further classify the cut wire ducts through the distribution mechanism, and directly distribute wire ducts of different specifications and lengths for subsequent assembly work, thereby further improving assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
