[0011] A method for finding a material head, characterized in that it comprises the following steps:

[0012] S1. Equipment initialization: cutting cylinder resets, pressing cylinder resets, vacuum nozzle closes, nozzle cylinder resets, and material search motor resets to initial position.

[0013] S2, the material-seeking action is started, the vacuum of the vacuum nozzle is turned on, the nozzle cylinder drives the vacuum nozzle to extend, and the material-seeking motor operates according to the set parameters to allow the vacuum nozzle to approach the coil. When the vacuum nozzle reaches the vacuum threshold, it means that the vacuum nozzle is adsorbed to the coil and the material-seeking is completed. If the material-seeking stroke is completed or the material-seeking limit sensor is triggered before the vacuum threshold is reached, the material-seeking motor stops and an alarm is sounded. After the fault is repaired, step S1 is restarted.

[0014] S3, the material-finding head action is started, and the nozzle cylinder controls the vacuum nozzle to retract. If the vacuum degree reaches the threshold after retraction, the material-finding head action is completed and enters the next step. On the contrary, if the vacuum degree of the vacuum nozzle does not reach the threshold, the material-discharging motor drives the coil holder to rotate according to the set parameters to discharge the material. After the material discharging is completed, the nozzle cylinder drives the vacuum nozzle to extend again. When the vacuum degree of the vacuum nozzle reaches the threshold, the nozzle cylinder controls the vacuum nozzle to retract again. If it still does not reach the threshold after retraction, the above-mentioned material-discharging action of the material-discharging motor and the extension and retraction action of the vacuum nozzle are repeated again. After repeating the set number of operations, the vacuum degree of the vacuum nozzle after retraction is still lower than the threshold, the material-finding motor retreats a distance, the nozzle cylinder controls the vacuum nozzle to extend, and the material-finding motor moves toward the coil according to other set parameters to detect whether the vacuum degree of the vacuum nozzle reaches the threshold, and restart the material-finding head action.

[0015] S4, the tape cutting action starts, the cutting cylinder controls the cutting knife to extend, the cutting knife cuts the tape at the material head, and then the cutting cylinder drives the cutting knife to retract.

[0016] S5. The material-seeking motor pulls the material head according to the set parameters, that is, the pulling distance and the pulling speed, and the material-discharging motor discharges the material synchronously. After the material-seeking motor completes the pulling distance, the pressing cylinder drives the pressing contact to extend.

[0017] S6. The base plate clamps the material head through the clamping mechanism and transfers it to the automated assembly and packaging production line for use.

[0018] Compared with the prior art, the present invention can achieve the following beneficial effects:

[0019] 1. Through the setting of the material-finding head equipment and the design of the material-finding method, through precise control and sensor feedback, the material head is ensured to be accurately placed at the target position. This equipment can efficiently and accurately complete the entire process from material-finding to material-pulling. Each step is precisely detected and controlled to ensure the automation degree and operation accuracy of the production line, thereby improving the overall production efficiency and product quality.

[0020] 2. Determine whether the material-seeking motor has moved to the material-seeking position by detecting the vacuum of the suction nozzle. When the suction nozzle moves to the material-seeking position, the expansion and contraction cylinder of the suction nozzle moves repeatedly. When the expansion and contraction cylinder of the suction nozzle retracts, the vacuum of the suction nozzle still meets the standard, indicating that the suction nozzle is sucking the material head at this time. If the expansion and contraction cylinder of the suction nozzle moves repeatedly four times and the vacuum of the suction nozzle still does not meet the standard, retreat a certain distance, and then perform a slow material search to more accurately find the appropriate suction position. If the vacuum of the suction nozzle retracts and still meets the standard, cut the tape and pull the material after cutting. This ensures the stability of pulling the material head position and the accuracy of obtaining the material head position.

[0021] 3. By setting up the storage space, the equipment space can be effectively utilized, and a number of coils can be prepared for the equipment for quick use when needed, which is conducive to further improving the overall production efficiency. The inclined storage plate setting also facilitates the use of coils.

[0022] 4. By integrating the nozzle assembly, cutting assembly and pressing assembly on the main frame board, it is helpful to reduce space occupancy, improve maintenance efficiency, and perform unified adjustment to ensure that the corresponding positions will not deviate, thereby ensuring the accuracy of the action.
