Technical Field

[0001] This invention relates to the field of mechanical manufacturing technology, specifically to a feeding mechanism, feeding method, and parameter determination method for an air-blowing contact body. Background Technology

[0002] Under current technological conditions, the loading of contact bodies mainly relies on clamping mechanisms. While this method is common, it has significant limitations in practical applications. When loading via clamping, the direct contact and pressure between the grippers and the contact body surface easily leads to clamp marks, indentations, and even deformation, affecting product quality and yield. Furthermore, these loading mechanisms are typically complex, containing multiple moving parts and transmission devices. Over long-term operation, they are prone to wear, jamming, or positioning deviations, increasing maintenance frequency and costs, potentially causing production line interruptions and reducing overall production efficiency. Therefore, current loading methods still require further improvement in reliability and safety. Summary of the Invention

The vibratory feeder 3-2 of the feeding vibratory feeder assembly 3 can discharge the contact body from the discharge channel 3-3 in a certain direction. The feeding mechanism can blow the contact bodies 4-5-5 into the chuck holes 5-2-1 of the clamping turntable mechanism 5 in sequence by blowing air for clamping. The clamping turntable mechanism 5 drives the station turntable 5-3 through the driver 5-1 to rotate the chuck 5-2 to different positions to complete the sequential clamping of the contact bodies 4-5-5.

[0025] Among them, the upper and lower adjustment plate 4-2 of the feeding mechanism 4 is connected to the mounting bracket 4-1. The mounting bracket 4-1 drives the upper and lower adjustment plate 4-2 to adjust the position of the material distribution component 4-5 up and down.

[0026] The left and right adjustment plate 4-3 is connected to the up and down adjustment plate 4-2, and the left and right adjustment plate 4-3 drives the material distribution component 4-5 to adjust left and right.

[0027] The rear baffle cylinder 4-4 and the material distribution component 4-5 are both connected to the left and right adjustment plates 4-3. The front baffle cylinder 4-6 is connected to the cylinder bracket 4-7, and the cylinder bracket 4-7 is connected to the material distribution component 4-5.

[0028] The drive end of the rear baffle cylinder 4-4 is connected to the rear baffle rod 4-5-3 of the material distribution assembly 4-5, and is used to drive the rear baffle rod 4-5-3 to complete the material blocking of the contact body. The drive end of the front baffle cylinder 4-6 is connected to the pressure block 4-5-7 of the material distribution assembly 4-5, and is used to drive the pressure block 4-5-7 of the material distribution assembly 4-5 to move up and down and drive the front baffle rod 4-5-9 to block the front end of the contact body 4-5-5.

[0029] The material distribution assembly 4-5 includes a quick-connect connector 4-5-1, a material distribution block rear cover 4-5-2, a rear baffle rod 4-5-3, a material distribution block 4-5-4, a contact body 4-5-5, a material distribution block cover 4-5-6, a pressure block 4-5-7, a baffle block 4-5-8, and a front baffle rod 4-5-9.

[0030] Among them, the material distribution block 4-5-4 includes a material blocking hole 4-5-4-1, a connecting countersunk hole 4-5-4-2, a cylinder bracket connecting screw hole 4-5-4-3, a material channel 4-5-4-4, a cover plate connecting screw hole 4-5-4-5, an air blowing hole 4-5-4-6, a stop rod hole 4-5-4-7, and an upper and lower moving groove 4-5-4-8.

[0031] Among them, the pressing block 4-5-7 includes a material stop block screw hole 4-5-7-1, a sliding side 4-5-7-2, a cylinder connection screw hole 4-5-7-3, and a pressing block material channel 4-5-7-4.

[0032] The round end of connector 4-5-1 connects to the air pipe, and the threaded end connects to the threaded hole of the rear cover 4-5-2 of the material distribution block for air input. The rear cover 4-5-2 of the material distribution block connects to the cover plate of the material distribution block via the threaded hole 4-5-4-5. Gas blows the contact body out through the quick connector 4-5-1 and the air blowing hole 4-5-4-6 of the material distribution block 4-5-4. The threaded end of the rear baffle rod 4-5-3 connects to the drive end of the rear baffle cylinder 4-4. The other end mates with the baffle hole 4-5-4-1 of the material distribution block 4-5-4 to block the contact body behind it during material blowing. The material distribution block 4-5-4 is connected to the left and right adjusting plates 4-3 by the connecting countersunk hole 4-5-4-2. The cylinder bracket connecting screw hole 4-5-4-3 is connected to the cylinder bracket 4-7. After the contact body is discharged from the discharge channel 3-3 in a certain direction by the feeding vibrating plate assembly 3, it passes through the material channel 4 of the material distribution block 4-5-4. -5-4-4 are fed sequentially. The material distribution block cover 4-5-6 is connected to the cover plate of the material distribution block through the countersunk hole and the connecting screw hole 4-5-4-5. The cylinder connecting screw hole 4-5-7 end of the pressure block 4-5-7 is connected to the drive end of the front baffle cylinder 4-6. The left and right sliding side 4-5-7-2 cooperates with the up and down moving groove 4-5-4-8 of the material distribution block 4-5-4. When the pressure block 4-5-7 descends and the contact body is blown out, the contact body passes through... The material passes through the pressing block channel 4-5-7-4 and enters the chuck hole 5-2-1 of the clamping turntable mechanism 5 for clamping. The countersunk hole of the material stop block 4-5-8 is connected to the material stop block screw hole 4-5-7-1 of the pressing block 4-5-7. The front stop rod 4-5-9 is fixed to the material stop block 4-5-8 and cooperates with the stop rod hole 4-5-4-7 of the material distribution block 4-5-4. When the pressing block 4-5-7 rises, the front stop rod 4-5-9 is used to block the contact body at the front end. The movement of the material distribution component 4-5 is initiated by the feeding vibrating disc component 3, which sequentially transports the contact bodies to the material distribution block 4-5-4's material channel 4-5-4-4. At this time, the stop rod 4-5-3 is in the reset state, as are the pressure block 4-5-7 and the front stop rod 4-5-9. This means the front stop rod has blocked the front end of the material distribution block 4-5-4's material channel 4-5-4-4, thus blocking the first contact body. The contact body moves until it reaches the front stop rod 4-5-9. At this point, the stop rod 4-5-3 extends to block the space between the first and second contact bodies, and then blocks the second and subsequent contact bodies. At this time, the pressure block 4-5-7 and the front stop 4-5-9 descend, and the front stop 4-5-9 no longer blocks the first contact body. At the same time, air is blown through the quick connector 4-5-1. The airflow blows the first contact body from the material channel 4-5-4-4 of the material distribution block 4-5-4 to the chuck hole 5-2-1 of the clamping turntable mechanism 5 for clamping. After that, the air blowing stops and all cylinders are reset. The work station turntable 5-3 of the clamping turntable mechanism 5 feeds the second contact body. The above actions are repeated to complete the feeding of the contact bodies in sequence.

[0033] In another embodiment of the present invention, the method for feeding the contact body includes the following steps: Vibration force is generated by the vibrating plate 3-2 of the feeding vibrating plate assembly 3. The vibration force arranges the contact bodies 4-5-5 in the order of small head forward interlocking and end to end, and discharges them from the discharge channel 3-3. Contact bodies 4-5-5 continuously and sequentially enter the material channel 4-5-4-4 of the material distribution block 4-5-4, and move along the material channel 4-5-4-4 until the front stop 4-5-9 blocks the contact body 4-5-5; Repeat the following steps until all contact bodies 4-5-5 have been loaded: Drive the rear stop rod 4-5-3 to extend between two consecutive contact bodies 4-5-5 and abut against the small end of the rear contact body 4-5-5, so that the contact body 4-5-5 and the rear contact body 4-5-5 cannot move forward. Drive the front stop lever 4-5-9 down, causing the front contact body 4-5-5 to move forward; Compressed air is blown into the main air inlet and blown towards the large end step of the contact body 4-5-5 through the oblique air inlet. The generated blowing force blows the contact body 4-5-5 into the chuck hole 5-2-1 of the chuck 5-2 and clamps the contact body 4-5-5 through the chuck 5-2. Drive the turntable 5-3 to rotate to the next station, drive the front stop 4-5-9 to move upward, and reset the rear stop 4-5-3; The next contact body 4-5-5 moves forward in the material channel of the dividing block 4-5-4 until the front stop 4-5-9 blocks the forward movement of the contact body 4-5-5.

[0034] In another embodiment of the present invention, the method for determining the parameters of the feeding mechanism of the air-blowing contact body includes the following steps: Based on the mass and dimensions of contact body 4-5-5 and the construction of air inlet 4-5-4-6, the initial parameter range of air blowing pressure and air blowing time is determined. Perform a calibration within the initial parameter range to determine the minimum air pressure required to initiate the contact body 4-5-5 from the material channel 4-5-4-4 of the dispensing assembly 4-5. P min ; Based on minimum blowing pressure P min A second calibration is performed, adjusting the blowing pressure and blowing time, to determine an optimal blowing pressure from the parameter combinations that ensure successful material feeding. P opt With the optimal blowing time T opt ; Based on optimal blowing pressure P opt And optimal blowing time T optThe calibration was performed three times, and the optimal blowing sequence was determined by adjusting the trigger timing of the blowing action. θ opt This ensures that the contact body 4-5-5 enters the chuck 5-2 in a stable posture; Optimal blowing pressure P opt Optimal blowing time T opt and optimal blowing timing θ opt Combine the parameters into blowing parameters and output them.

[0035] Specifically, determine the minimum blowing pressure required to activate the contact body 4-5-5 from the material channel 4-5-4-4 of the dispensing assembly 4-5. P min ,include: Set a reference blowing time that is greater than the time required for the complete movement of contact body 4-5-5; Start with a blowing pressure lower than the initial parameter range, gradually increase the blowing pressure, and trigger a single blowing action; When continuous N If each blowing action successfully initiates contactor 4-5-5 and detaches from material channel 4-5-4-4, the current pressure value will be used as the minimum blowing pressure. P min ,in, N The threshold value is a preset positive integer.

[0036] Specifically, based on the minimum blowing pressure P min A second calibration is performed, adjusting the blowing pressure and blowing time, to determine an optimal blowing pressure from the parameter combinations that ensure successful material feeding. P opt With the optimal blowing time T opt ,include: Set the initial blowing pressure to be greater than the minimum blowing pressure. P min ; Determine the shortest blowing time required for the contact body 4-5-5 to completely leave the blowing port 4-5-4-6 from activation. T travel ; Calculate the shortest blowing time T travel With preset margin time Δ T The sum of these values ​​is used as the optimal blowing time. T opt ; Maintain optimal blowing time T opt Keep the initial blowing pressure unchanged and conduct a feeding test; Will satisfy continuityM The lowest pressure value among the initial blowing pressures of the first successful feeding is taken as the optimal blowing pressure. P opt ,in, M The threshold value is a preset positive integer, and M ≥N.

[0037] Specifically, it also includes: Determine a set of optimal blowing pressures P opt With optimal blowing time T opt Then, the optimal blowing pressure was determined. P opt and optimal blowing time T opt Verification includes: The feeding mechanism is continuously controlled by a combination of air blowing parameters. K Next feeding cycle; Statistically analyze and confirm whether the success rate of continuous material feeding meets the preset reliability standard; If the optimal blowing pressure is not achieved, the optimal blowing pressure should be re-determined. P opt With optimal blowing time T opt .

[0038] The parameter determination method of this invention decomposes the complex parameter debugging process into steps such as determining the initial range, finding the start-up threshold, coordinating pressure and time, and adjusting the trigger sequence. The output of the previous step serves as the input for the next step, forming a standardized and reproducible engineering method. This avoids the blindness and randomness of debugging, allowing for the rapid and reliable acquisition of a set of usable operating parameters, thus shortening the cycle of new equipment debugging and new product replacement.

[0039] The goal is to find the optimal parameter combination that balances reliability and economy to improve overall feeding performance. Through the aforementioned secondary calibration, the aim is to find the lowest possible air pressure while ensuring successful feeding. The final determined parameters ensure a 100% feeding success rate while minimizing energy consumption (saving compressed air), impact (reducing the risk of collision damage between the contact body and the chuck), and vibration and noise, thereby improving the equipment's operational economy, stability, and service life.

[0040] The system uses N / M consecutive successes as the criterion for step determination and provides a verification step based on large-scale continuous operation (K cycles). This verification mechanism, based on statistical reliability, ensures that the determined parameter combination is a robust solution that can withstand long-term production testing. It improves the first-pass yield and overall stability of the feeding mechanism using these parameters in production, guarantees the cycle time and quality of the automated production line, and ensures the robustness and production consistency of the parameter combination.

[0041] Beneficial effects of the embodiments of the present invention: The vibratory feeder assembly can discharge the contact body from the discharge channel in a certain direction. The feeding mechanism can sequentially load the contact body into the chuck of the clamping turntable mechanism. The clamping turntable mechanism can rotate the chuck to different positions to complete the sequential clamping of the contact body. The feeding mechanism blows the contact body into the chuck for clamping by blowing air. This feeding method avoids the pinching injury caused by the gripper clamping the material, simplifies the feeding mechanism and improves the feeding efficiency. The parameter determination method of this invention realizes the systematization and logic of the parameter determination process, significantly improves the debugging efficiency and reliability, and minimizes energy consumption and impact while ensuring successful feeding.

Therefore, any substitution of equivalent components or equivalent changes and modifications made within the scope of protection of this patent should still fall within the scope of this patent.
