Abstract
Description
Technical Field
[0001] This utility model relates to the field of automation technology for non-ferrous metal metallurgical equipment, specifically a collaborative control device for the rod-passing unit of a nickel starting electrode processing unit. Background Technology
[0002] In nickel starter sheet processing, the rod threading unit needs to achieve precise alignment between the conductive rod and the starter sheet lifting lugs. Traditional rod threading processes rely on manual monitoring, which leads to problems such as line shutdowns due to threading failures, low efficiency in handling bending plate jams, and disorganized process connections after resetting. In existing technologies, although the rod threading unit has basic functions such as rod storage and separation, and rod pushing and threading, it lacks a coordinated control strategy, resulting in equipment utilization of less than 30% and an average fault repair time of more than 15 minutes. Utility Model Content
[0003] Therefore, the purpose of this utility model is to provide a collaborative control device for the rod threading unit of a nickel starting electrode processing unit. Through a PLC controller, the device enables the coordinated operation of the rod storage platform, rod separating device, rod pushing chain, ear expanding device and flipping mechanism, establishes graded fault handling, reduces the scope of fault impact, improves equipment utilization compared to traditional full-line shutdown, and shortens the average repair time by using a touch screen to locate fault points in three dimensions.
[0004] To solve the above-mentioned technical problems, according to one aspect of the present invention, the present invention provides the following technical solution: a collaborative control device for the rod-piercing unit of a nickel starting electrode processing unit, comprising: A rod storage platform, the rod storage platform being used for flipping and supplying rods; The bar separating device is used to separate and transfer individual bars to a chute. A pusher chain, the pusher chain being used for step conveying; Ear-expanding device, the ear-expanding device being used to open the lifting ears; A flipping mechanism is used to flip the starting electrode plate, which has been pushed into place by the push rod, from a horizontal state to a vertical state with the copper rod as the axis.
[0005] As a preferred embodiment of the collaborative control device for the rod threading unit of the nickel starting electrode processing unit described in this utility model, the rod storage platform, rod separating device, rod pushing chain, lug expanding device and flipping mechanism are connected and coordinated through a PLC controller.

Among them, the entire machine will be safely shut down when two points fail simultaneously; if the same point fails three times in a row, the equipment will be locked and needs to be repaired.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0016] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.
[0018] This utility model provides a collaborative control device for the rod threading unit of a nickel starting electrode processing unit. It realizes the coordinated operation of the rod storage platform, rod separating device, rod pushing chain, ear expanding device and flipping mechanism through PLC controller, establishes hierarchical fault handling, reduces the scope of fault impact, improves equipment utilization rate compared with traditional full line shutdown, and shortens the average repair time by three-dimensional positioning of fault points on the touch screen.
[0019] Figures 1-2 The diagram shown is an overall structural schematic of an embodiment of the collaborative control device for the rod-piercing unit of a nickel starting electrode processing machine according to this utility model. Please refer to [link / reference]. Figures 1-2 The main structure of this embodiment includes: Bar storage platform 1, bar storage platform 1 is used for flipping and supplying bars; Bar separating device 2, which is used to separate and transfer single bars to the chute; Pusher chain 3, pusher chain 3 is used for step conveying; Ear-expanding device 4, used to open the lifting ears; The flipping mechanism 5 is used to flip the starting plate, which has been pushed into place by the copper rod, from a horizontal state to a vertical state. The storage platform 1, bar separating device 2, bar pushing chain 3, ear expanding device 4, and flipping mechanism 5 are connected and coordinated via a PLC controller. The stepping frequency of the bar pushing chain 3 is linked with the signal of the bar separating device 2 to ensure that the interval between single bars is ≥0.5 seconds. The cylinder pressure of the ear expanding device 4 is dynamically adjusted based on the feedback of the bar pushing resistance, ranging from 0.2 to 0.8 MPa. The speed of the flipping output chain matches the receiving rate of the downstream equipment, with an error of ≤±5%. The system also includes fault classification, which includes bar jamming in the chute, bar pushing port blockage, and bar threading failure. A continuous high level of the chute photoelectric signal for >3 seconds indicates a single-point fault. When two points of fault occur simultaneously, the entire machine will be safely shut down. Three consecutive faults at the same position require the equipment to be repaired. The PLC controller has status memory and resume transmission functions. After manual repair, it can be reset via the touch screen, with a resume position error of ≤2mm. The touch screen displays the fault location and historical records in real time. In practical use, a Siemens S7-1215 PLC is used as the core controller. Through the PROFINET protocol, with a cycle of ≤100ms, the device and photoelectric sensors are connected. After the storage bar platform 1 is flipped, the bar separating device 2 separates individual bars through step-by-step bar feeding and moves them to the chute. The step signal of the bar pushing chain 3 is calculated by the PLC controller to determine the conveying interval. When the photoelectric signal at the chute inlet is continuously high for >3 seconds, the storage bar platform 1 is paused and an alarm is triggered. When the infrared sensor at the bar pushing port has material for >5 seconds, the bar pushing motor is paused. When the bar insertion detection timeout exceeds 2 seconds, the flipping mechanism 5 is paused. The touch screen displays the three-dimensional fault location and historical records in real time and stores 100 fault data entries with timestamps. Through the coordinated control of the entire process, including the flipping and feeding of bar storage platform 1, single bar separation by bar separation device 2, step conveying by bar pushing chain 3, dynamic pressure adjustment by ear expansion device 4, bar pushing and threading, and 90° flipping and output, combined with the graded handling mechanism for bar jamming in the chute, blockage of the bar pushing port, and failure of bar threading, the system achieves accurate fault location and partial pause. The PLC controller status continuation technology eliminates reset misalignment, and the three-dimensional positioning of the touch screen shortens the fault repair time. This solves the technical pain points of large downtime range and difficult handling of bending plate jamming in the traditional bar threading process, and improves the equipment utilization rate by more than 40%.
[0020] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
