Description

Technical Field

[0001] This invention relates to the field of phosphor bronze ball cleaning technology, specifically a fully automatic phosphor bronze ball cleaning system. Background Technology

[0002] When cleaning phosphor bronze balls, a vibratory polishing machine is used. Currently, the cleaning of phosphor bronze balls is carried out manually by manually feeding the phosphor bronze balls into the vibratory polishing machine, then manually adding chemicals to the polishing machine, then turning on the polishing machine to vibrate and clean, and finally manually opening the drain valve to discharge the cleaning wastewater in the polishing machine. This cycle is repeated twice by manually adding chemicals and tap water for vibratory cleaning.

[0003] Existing technical defects: 1) Low efficiency of manual operation. The current process requires manual completion of the entire process of feeding, mixing, water injection and sewage discharge. Each cleaning requires repeating the manual process twice, which is labor-intensive and time-consuming. In addition, the cleaning quality of phosphor bronze balls is inconsistent. Traditional cleaning methods require an average of 2 people to work together.

[0004] Therefore, in order to correct the above-mentioned defects, we propose a fully automated phosphor bronze ball cleaning system. Summary of the Invention

[0005] The technical problem solved by this invention is to provide a fully automatic phosphor bronze ball cleaning system.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a fully automatic phosphor bronze ball cleaning system, comprising a phosphor bronze ball collection silo and a vibratory polishing machine. The phosphor bronze ball collection silo is equipped with an automatic gate. It also includes a main water inlet pipe and a chemical dispensing system located next to the phosphor bronze ball collection silo. The main water inlet pipe and the chemical dispensing system are connected to achieve automatic chemical dispensing. The output port of the chemical dispensing system is connected to a chemical solution pipe and a sewage pipe. The chemical solution pipe is connected to a chemical solution branch pipe, which is connected to the corresponding vibratory polishing machine silo. A guide plate is installed outside the automatic gate, and the outlet of the guide plate is located at the opening of the vibratory polishing machine silo, enabling the automatic addition of phosphor bronze balls into the vibratory polishing machine. The vibratory polishing machine is equipped with an automatic gate to achieve automatic discharge of the phosphor bronze balls.

[0007] Furthermore, the drug preparation system includes a drug storage tank, a pneumatic diaphragm pump, and a mixing vessel. The main water inlet pipe is connected to the drug storage tank, and the inlet and outlet ends of the pneumatic diaphragm pump are connected to the drug storage tank and the mixing vessel, respectively, via connecting pipes.

[0008] Furthermore, the main water inlet pipe is connected to the dosing system through one valve of the three-way valve, the other valve of the three-way valve is connected to a clean water pipe, the clean water pipe is connected to a clean water branch pipe, and the outlet end of the clean water branch pipe is connected to the vibrating polishing machine compartment.

[0009] Furthermore, it also includes a chain conveyor, with the discharge port of the vibratory finishing machine facing the chain conveyor.

[0010] Furthermore, the discharge port of the vibratory finishing machine is equipped with a self-resetting trapezoidal locking device to control the opening and closing of the discharge port.

[0011] Furthermore, a discharge buffer device is installed on one side of the upper end of the chain conveyor. The discharge buffer device is located on the opposite side of the discharge port. The discharge buffer device includes a support frame that is screwed to the chain conveyor. A cylinder is installed on the support frame. The telescopic end of the cylinder faces the discharge port and is fixed with a baffle. A rubber pad is installed on the side of the baffle facing the discharge port to realize the automatic discharge of the phosphor bronze balls.

[0012] Furthermore, the outlet of the vibratory finishing machine has a baffle extension plate around it, which is fixed to the chain conveyor.

[0013] Furthermore, a gantry frame is installed on the chain conveyor, and a high-pressure automatic cleaning water gun is installed on the gantry frame. The high-pressure automatic cleaning water gun of the high-pressure washing machine realizes automatic high-pressure washing of the phosphor bronze balls discharged from the vibrating finishing machine.

[0014] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention achieves fully automated operation of the phosphorus copper ball cleaning process through a PLC integrated control system, focusing on solving three major technical problems: First, it constructs a precise automated control system, employing an automatic quantitative feeding device with an error of less than ±3%, coupled with an intelligent reagent dilution system with viscosity adaptive adjustment function, and realizing programmable timing control of the cleaning / drainage cycle; second, it optimizes process parameter control, ensuring uniform mixing of reagents through a mixing station, using solenoid valves with an accuracy of ±0.3L to control the liquid dosage, and establishing a standardized cleaning timing model including a closed-loop compensation algorithm; finally, it improves the quality traceability system, integrating an online monitoring module to automatically record process parameters for each batch, and seamlessly connecting with the subsequent drying process to form a complete closed-loop automated cleaning production. This solution integrates the 12 discrete processes of traditional manual operation into 4 automated modules, improving process stability by more than 60%. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention provides a technical solution:

[0023] like Figure 1 As shown, a fully automatic phosphorus copper ball cleaning system is designed with the following system architecture: This system uses a Siemens PLC as the core controller and integrates 6 functional modules: 1) Feeding module: equipped with an Airtac SC50 cylinder (thrust 392N) to drive the copper ball discharge gate; 2) Liquid preparation module: 200L mixing station (motor power 0.75kW); 3) Cleaning module: vibratory finishing machine; 4) Sewage discharge module: lever mechanism (efficiency ratio 1:3); 5) Ball discharge module: self-resetting automatic switching mechanism; 6) Transmission module: stainless steel chain conveyor (speed 0.5-1m / s);

[0024] 2. Key technological breakthroughs: (1) Development of dynamic viscosity compensation technology: The control algorithm based on the temperature-viscosity relationship is: V(t)=V0×[1+0.023(T-25)] where V0 is the standard viscosity (at 25℃) and T is the real-time temperature. The system collects data through the PT100 temperature sensor and dynamically adjusts the operating parameters of the diaphragm pump. (2) Anti-clogging volleyball and sewage discharge automatic operation mechanism: The innovative design includes two core technologies: self-resetting automatic wedge volleyball gate technology; lever force enhancement mechanism + communicating vessel technology to realize automatic sewage discharge with impurities.

[0025] 3. Process control flow:

[0026] (1) Automatic feeding stage of phosphor bronze balls (40±5 seconds) -- PLC receives the ready signal of the polishing machine -- Cylinder pushes the gate to open (stroke 70mm) -- Infrared sensor verifies the feeding amount;

[0027] (2) Intelligent liquid preparation stage (30±5 seconds) -- Solenoid valve water injection (flow rate 15L / min) -- Pneumatic diaphragm pump injection of agent (flow rate 20L / min) -- Two-stage stirring (low speed 30rpm / high speed 60rpm); (3) Cleaning and sewage discharge stage (260±10 seconds) -- First cleaning (120 seconds) -- Lever automatic sewage discharge (20 seconds) -- Second cleaning and discharge (120 seconds).

[0028] Details are as follows:

[0029] This automated phosphor bronze ball cleaning system employs Siemens PLC centralized control and achieves precise material feeding (opening and closing accuracy ±0.2mm) via a non-standard arc-shaped gate driven by an Airtac cylinder. The system first injects a measured amount of tap water into the mixing station via an adjustable solenoid water valve, while simultaneously injecting the chemical agent via a pneumatic diaphragm pump. The mixing station is equipped with a dual-stage liquid level sensor (upper liquid level alarm accuracy ±3mm, lower liquid level shutdown protection) and a variable frequency stirring mechanism (speed adjustable from 30-60rpm) to ensure that the viscosity deviation of the mixed solution is ≤5%. The PLC-controlled solenoid valve group automatically and quantitatively injects the diluted chemical agent and tap water at a 5:2 ratio (adjustable) into the vibratory finishing machine. After a primary cleaning of 120±5 seconds, a lever-type drain mechanism (force ratio 1:3) completes a 20-second drain. After secondary cleaning, the finished product is conveyed to the drying process via a self-resetting discharge port (trapezoidal piston rod + silicone buffer pad) through a conveyor chain (speed 0.5m-1.0 / s), achieving a cleaning qualification rate of 98.5% throughout the process.

[0030] The specific details regarding the above are as follows:

[0031] Please see Figure 2-6 The entire cleaning system includes a phosphor bronze ball storage silo 1, a PLC control system, and a vibratory polishing machine 2. The phosphor bronze ball storage silo 1 is equipped with an automatic gate 3. It also includes a main water inlet pipe and a dosing system located next to the phosphor bronze ball storage silo 1. The main water inlet pipe 5 is connected to the dosing system. The output port of the dosing system is connected to a chemical pipe 9. The chemical pipe 9 is connected to a chemical branch pipe 10. The chemical branch pipe 10 is connected to the vibratory polishing machine 2. A guide plate 4 is installed outside the automatic gate 3. The outlet of the guide plate 4 is located at the opening of the vibratory polishing machine 2. The dosing system includes a storage tank 7, a pneumatic diaphragm pump 8, and a mixing tank 6. The main water inlet pipe 5 is connected to the storage tank 7. The inlet and outlet of the pneumatic diaphragm pump 8 are connected to the storage tank 7 and the mixing tank 6 respectively through connecting pipes.

[0032] The pneumatic diaphragm pump 8 introduces the medicine liquid in the medicine storage tank 7 into the mixing tank 6. At the same time, tap water also enters the mixing tank 6 for stirring. The diluted medicine liquid enters the vibratory finishing machine 2 through the medicine water pipe 9 and the medicine water branch pipe 10. At the same time, the phosphor bronze balls in the phosphor bronze ball storage bin 1 also enter the bin of the vibratory finishing machine 2. The vibratory finishing machine 2 is then turned on for cleaning.

[0033] After cleaning with the chemical solution, the drain port of the vibratory polishing machine 2 is automatically opened to drain the wastewater. Then, clean water is used to continue cleaning. The main water inlet pipe 5 is connected to the chemical dispensing system through one valve of the three-way valve. The other valve of the three-way valve is connected to the clean water pipe 11. The clean water pipe 11 is connected to the clean water branch pipe 12. The outlet end of the clean water branch pipe 12 is connected to the chamber of the vibratory polishing machine 2.

[0034] After rinsing with clean water, the discharge port of the vibratory finishing machine 2 is automatically opened by the self-resetting trapezoidal locking device, and the cleaned phosphor bronze balls enter the chain conveyor 13. On the chain conveyor 13, the phosphor bronze balls will undergo dry and wet separation, that is, the liquid will seep down from the chain conveyor 13. The self-resetting trapezoidal locking device adopts the existing technology structure, which mainly includes baffles, connecting rods, hinges, springs, drive cylinders, etc.

[0035] In addition, when the phosphor bronze balls enter the chain conveyor 13 from the discharge port, in order to prevent the phosphor bronze balls from rushing out of the chain conveyor 13 due to excessive parabolic path when entering the chain conveyor 13 from the discharge port, a discharge buffer device 15 is installed on one side of the upper end of the chain conveyor 13. The discharge buffer device 15 is located on the opposite side of the discharge port. The discharge buffer device 15 includes a support frame 151 that is screwed to the chain conveyor 13. A cylinder 152 is installed on the support frame 151. The telescopic end of the cylinder 152 faces the discharge port and is fixed with a baffle 153. A rubber pad is installed on the side of the baffle 153 facing the discharge port. That is, when the phosphor bronze balls enter the chain conveyor 13 from the discharge port, if the path is too large, it will be blocked by the rubber pad.

[0036] Similarly, the periphery of the discharge port of the vibratory finishing machine 2 has a baffle extension plate 16, which is fixed on the chain conveyor 13. The baffle extension plate 16 and the discharge buffer device 15 cooperate in both directions to ensure that the phosphor bronze balls enter the chain conveyor 13.

[0037] Meanwhile, a gantry frame is installed on the chain conveyor 13, and a high-pressure automatic cleaning water gun 17 is installed on the gantry frame. The high-pressure automatic cleaning water gun 17 is connected to a clean water pipe to further rinse the phosphor bronze balls on the chain conveyor 13.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
