Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electroplating industrial equipment, in particular to a full-automatic circulating conveying system and method of a flying bar of an intelligent electroplating production line. BACKGROUND

[0002] With the increasingly stringent requirements of the state on environmental protection, it is almost impossible to build a new electroplating line project, and only optimization and reconstruction of old electroplating line projects on the original electroplating site can be carried out, and the space in the electroplating plant is too nervous (the space occupied by the storage of the empty flying bar after unloading, and the space occupied by various auxiliary equipment); In addition, there are generally two ways for the operation of the empty flying bar of the electroplating line at present: 1. After the loaded flying bar is unloaded at the unloading position, the empty flying bar is automatically returned to the loading position by the internal crane of the production line for reloading, which requires the setting of a transfer tank, resulting in an excessively long production line, and affecting the production process of the electroplating line and reducing the production efficiency; 2. The empty flying bar is manually transferred from the unloading position to the loading position, which requires a large amount of manpower and plant space, and factors such as the working enthusiasm and proficiency of personnel will affect the production efficiency of the entire electroplating line. SUMMARY

[0003] In view of the deficiencies of the prior art, the present application provides a full-automatic circulating conveying system and method of a flying bar of an intelligent electroplating production line, which solves the problems of space nervousness and empty flying bar transfer efficiency in the existing electroplating plant, and the core of the present application is to realize the full automation and high efficiency of the flying bar of the electroplating production line in the circulating process of "unloading-empty return-loading".

[0004] The innovation is not in the creation of a single component, but in the overall layout of the conveying system, the cooperative relationship between the execution mechanisms, and the automatic control logic based thereon.

Through the coordinated action of the lifting vertical cylinder and the horizontal cylinder, the automatic hooking and unhooking of the empty flying bar, the vertical lifting / descending and the horizontal transmission are realized; the conveying chain mechanism is provided with two parts, which are located between the first transfer mechanism and the second transfer mechanism and between the third transfer mechanism and the fourth transfer mechanism respectively. The horizontal transmission or temporary storage of the empty flying bar is realized through the conveying chain; the translation trolley mechanism is provided with one part, which moves horizontally to transfer the empty flying bar to the feeding side; Further comprising: a circulating conveying system is arranged above the rack of the electroplating production line at one end of feeding and discharging, and the translation trolley mechanism is arranged between the second transfer mechanism and the third transfer mechanism; Further comprising: a transfer mechanism, comprising: a vertical cylinder, a horizontal cylinder, a flying bar lifting arm, a live hook, a guide rail, a guide block and a transfer mechanism rack; the flying bar lifting arm is connected with the live hook, and the guide rail is located inside the two sides of the transfer mechanism rack, wherein the guide rail is provided with a guide block inside; Further comprising: a conveying chain mechanism, comprising: a conveying chain, a driving motor, a limiting block, a limiting cylinder, a clamping mechanism and a conveying chain mechanism rack, wherein the conveying chain is arranged inside the two sides of the conveying chain mechanism rack, the driving motor is arranged on one side of the upper end of the conveying chain mechanism rack, the limiting cylinder is arranged below the conveying chain mechanism rack at the two side positions, and the output end of the limiting cylinder is provided with a limiting block, and the clamping mechanism is arranged on one side above the conveying chain mechanism rack.

[0006] Preferably, a full-automatic circulating conveying method of the flying bar of the intelligent electroplating production line comprises the following steps: S1: The loaded flying bar after completing each production process is conveyed to the lower shelf by the transfer mechanism inside the feeding end of the production line. After the worker unloads the hanger and the product, a signal of the empty flying bar returning is given to the system, and a discharging confirmation button is pressed. At this time, the lower shelf lifting mechanism starts to reduce the speed and lift the empty flying bar to the upper position close to the switch sensor; S2: The system receives an empty flybar on the lower lifting mechanism in place proximity switch sensor signal, and controls the electromagnetic valve to push down the vertical cylinder in the first transfer mechanism, and then controls the electromagnetic valve to push the horizontal cylinder in the first transfer mechanism to the lower position, and the flybar lifting arm in the first transfer mechanism has moved to the lower side of the empty flybar, and then the vertical cylinder pushes up to drop the empty flybar onto the charged hook, and the system receives the hook guide signal to control the first transfer mechanism to transfer the empty flybar to the conveying chain of the conveying chain mechanism; the conveying chain mechanism receives the travel switch signal of the empty flybar on the conveying chain, and starts the conveying chain mechanism drive motor to convey the empty flybar to the other end of the conveying chain mechanism, and the other end of the conveying chain mechanism is provided with a plurality of travel switches, limit blocks and limit cylinders; the second transfer mechanism further transfers the empty flybar to the translation trolley mechanism; S3: The translation trolley mechanism receives the empty flybar falling into the translation mechanism through the proximity switch, and starts the drive motor to translate to the feeding side, and then the third transfer mechanism transfers the empty flybar to the conveying chain mechanism. S4: After the empty flybar is hung, the loaded flybar is conveyed to the pretreatment end of the electroplating production line by the internal transfer mechanism and the conveying chain mechanism of the feeding end of the production line.

[0007] Preferably, in step S1, the action of the speed reducer elevator and the first transfer mechanism is triggered by the sensor after the hook is in place.

[0008] Preferably, in step S2, the action of the conveying chain mechanism and the translation mechanism is triggered by the sensor after the empty flybar is in place.

[0009] The present application provides a flybar full-automatic circulation conveying system and method of intelligent electroplating production line. Compared with the prior art, the following beneficial effects are possessed: Closed-loop automatic conveying or temporary storage system: a complete and closed automatic circulation path including "unloading-empty return-feeding" is constructed, automatic empty return of the flybar is realized, manual intervention is not needed, production efficiency is greatly improved, and labor intensity is reduced.

[0010] Multi-mechanism coordinated transfer method: accurate and automatic transfer between the flybar at multiple key nodes (such as lifting mechanism hook point, transfer mechanism connection point, conveying chain mechanism connection point, and translation trolley connection point) in the circulation path and different mechanisms is defined, and a stable and reliable automatic transfer scheme is formed.

[0011] Core function and structure: The "transport mechanism" and "conveying chain mechanism" are identified as the core functional units. The standard action of the transport mechanism is composed of the "lifting cylinder" and "transmission cylinder" two linear motion combinations, which realizes the accurate grabbing, shifting and placing of the air flying bar between the "vertical down / up rack position lifting mechanism", "horizontal conveying chain mechanism" and "translation trolley". The standard action of the conveying chain mechanism is the horizontal conveying and temporary storage motion combined with the travel switch signal. This modular design makes the mechanism reusable in multiple positions of the production line (downloading end, pre-treatment end, and loading end of the production line).

[0012] Sensor-based automation control logic: The entire system operation relies on the trigger signals of sensors (such as sensing hooks and sensing flying bar position), so that the sequential actions of deceleration machines, control cylinders, conveying chains, translation trolleys and other execution elements are realized. This event-triggered control logic is the core of achieving full-automatic circulation, ensuring the coherence and reliability of the process.

[0013] Spatial stereoscopic layout: The space above the production line is ingeniously utilized to set up the air flying bar automation conveying or temporary storage system, optimizing the space utilization rate of the electroplating plant and avoiding interference with the main process of the production line.

[0021] Second embodiment A full-automatic circulating conveying method of a flying bar of an intelligent electroplating production line, comprising the following steps: S1: The loaded flying bar after completing each production process is conveyed to the lower rack position 1 by the internal conveying mechanism (similar to the conveying chain mechanism 8 and the fourth transfer mechanism 9) of the production line. After the worker unloads the hanger and the product, a signal of the empty flying bar 12 is transmitted to the system through the unloading confirmation button. At this time, the speed reducer of the lower rack position lifting mechanism 2 is started to lift the empty flying bar 12 to the upper position close switch sensor. S2: The system receives the signal of the empty flying bar 12 on the lower rack position lifting mechanism 2 upper position close switch sensor, controls the electromagnetic valve to push down the vertical direction cylinder 14 in the first transfer mechanism 3, then controls the electromagnetic valve to push the horizontal direction cylinder 15 in the first transfer mechanism 3 to the lower rack position 1. The flying bar lifting arm 16 in the first transfer mechanism 3 has been moved to the lower side of the empty flying bar 12, then the vertical direction cylinder 14 is pushed up to make the empty flying bar 12 fall into the electrified hook 17. The system receives the hook guide signal to control the first transfer mechanism 3 to transfer the empty flying bar 12 to the conveying chain 21 of the conveying chain mechanism 4.

The subsequent path refers to the paths of S2 and S1 until the empty flying bar is conveyed to the feeding position. S4: After the empty flying bar 12 is hung, the loaded flying bar is conveyed to the pretreatment end of the electroplating production line by the internal conveying mechanism (similar to the first transfer mechanism 3 and the conveying chain mechanism 4) of the feeding end of the production line.
