Description

Technical Field

[0001] The invention relates to the technical field of electronic equipment, and in particular to a synchronous pay-off device for a plurality of large-volume cable drums. Background Art

[0002] Cables are required in many products or equipment. These cables are usually obtained by unwinding and cutting a packaged cable roll. In the production process, in order to improve production efficiency, it is often necessary to use a wire unwinding machine to automatically unwind the wire so that it can automatically feed the subsequent automation equipment.

[0003] For example, the Chinese utility model patent with patent announcement number CN207726490U discloses a fully automatic wire feeding mechanism for wiring terminals, which includes a frame, a wire reel clamping device at one end of the frame, and an electromagnetic brake motor that drives the wire reel clamping device to release the wire. A wire storage mechanism is fixedly connected to the side of the frame close to the wire reel clamping device; a guide mechanism is fixedly connected to the side of the wire storage mechanism away from the wire reel clamping device; and a detection mechanism is fixedly connected to the side of the guide mechanism away from the wire storage mechanism. It can realize automated operation and improve work efficiency.

[0004] Another example is a Chinese invention patent with the patent publication number CN115108389A, which discloses a wire-releasing machine, which includes n wire-releasing bodies stacked in sequence longitudinally, where n≥2; each wire-releasing body includes a wire-releasing frame and a wire-releasing shaft, a tension structure, a tension collector and a driving mechanism located on the wire-releasing frame, a wire bundle to be released is wound on the wire-releasing shaft, the tension structure is used to support the wire bundle released by the wire-releasing shaft, the tension collector is used to collect the tension of the wire bundle in the tension structure, and the driving mechanism is used to control the wire-releasing shaft to rotate at a set speed according to the tension of the wire bundle. This structure can save space, avoid interference between the wire-releasing machine and other production equipment, and make the speed of the wire-releasing shaft match the tension of the wire bundle, avoid affecting the yield of the wire bundle or causing the wire bundle to knot, and ensure smooth and stable wire-releasing.

[0005] However, in the above-mentioned fully automatic cable terminal feeding mechanism, the cable reel needs to be unpacked and fixed to the reel clamping device, and then the wires need to be guided to be threaded, pulled, and arranged, and then the electromagnetic brake motor drives the reel clamping device and the cable reel to rotate for wire release; in the above-mentioned wire release machine, the cable reel needs to be unpacked and fixed to the driving mechanism through the wire release shaft, and the wires need to be guided to be threaded, pulled, and arranged, and then the drive mechanism drives the wire release shaft and the cable reel to rotate for wire release. This structure is only suitable for placing small-sized cable reels. The length of the cable or electronic wire in each reel is generally within 500-1000 meters. A reel of cable or electronic wire will be used up in a short time. After use, it needs to be manually unpacked and replaced with a new cable reel, and then the wires need to be threaded, guided, pulled, and arranged. Frequent unpacking, reloading, and wire arrangement have high labor intensity and low production efficiency. In addition, wire entanglement, pulling and breaking are prone to occur during operation, and further improvement is needed. Summary of the invention

[0006] In order to solve the above problems, the purpose of the present invention is to provide a synchronous pay-out device for multiple large cable reels, on which multiple large cable reels can be placed at the same time for synchronous pay-out. During pay-out, each large cable reel is independently controlled to ensure appropriate pay-out tension and avoid pulling, breaking or entanglement of the wire, which can greatly reduce the intermediate reel changing time, improve production efficiency and reduce labor intensity.

[0007] To achieve the above object, the present invention adopts the following technical solutions: A synchronous wire-releasing device for multiple large-volume cable drums, including a wire-feeding drive mechanism and a wire-releasing tension detection mechanism, wherein the wire-feeding drive mechanism includes at least two automatic clutches, an independent cable drum drive shaft and a cable drum support shaft, two or more of the automatic clutches are connected in series at one end and are connected to a servo motor, each of the automatic clutches is provided with an active synchronous wheel, each of the independent cable drum drive shafts is provided with a driven synchronous wheel, the active synchronous wheel is connected to the driven synchronous wheel through a synchronous belt, each of the independent cable drum drive shafts and a cable drum support shaft constitute a group, on which a cable drum is placed and driven to rotate; the wire-releasing tension detection mechanism includes a bracket, a vertical wire-releasing guide roller, a horizontal wire-releasing guide roller, a steering roller group, an upper roller group, a sliding lifting wheel group and a wire-out roller group, each cable to be transported is independently led out from a cable drum and then passes through the The vertical pay-off guide roller, the horizontal pay-off guide roller, the steering roller group, the upper roller group, the sliding lifting wheel group and the outlet roller group are then transported to the processing procedure through the correction roller group.

The cables pass around the bottom of the independent sliding lifting wheels and use their tension to drag the independent sliding lifting wheels to move up and down. The bracket is provided with detection sensors for respectively detecting the upper, middle and lower positions corresponding to each of the independent sliding lifting wheels. The detection signals of the upper, middle and lower detection sensors corresponding to each of the independent sliding lifting wheels are used to control the clutch state of an automatic clutch.

The sliding lifting wheel group is provided with independent sliding lifting wheels corresponding to the number of cable reels. The cable uses its tension to drag the independent sliding lifting wheel for movable lifting, and then the detection sensor detects the upper, middle and lower position signals corresponding to each independent sliding lifting wheel, and uses the detection signal to control the clutch state of each automatic clutch, thereby controlling each cable reel to rotate or stop, ensuring that each cable reel independently pays out the wire without being interfered by adjacent reels.

[0020] 4. The sliding lifting wheel group structure and the installation structure corresponding to the detection sensor of the present invention are cleverly designed, and do not require the use of a special tension meter for detection. The overall cost is low and the use is reliable.
