The debugging core of the carrier tape packaging machine revolves around three core links: feeding accuracy, sealing effect, and cutting accuracy. The overall debugging needs to first complete basic calibration and then gradually link testing
1. Basic calibration before startup
1.1 Power and gas source inspection
-Confirm that the three-phase power supply voltage is stable at 380V ± 10%, the single-phase equipment is 220V ± 10%, and the grounding is reliable; Pneumatic models need to adjust the air source pressure to 0.4-0.6MPa and check for any air leaks or bends in the air pipes.
-Attention: Failure to ground or abnormal air pressure may cause equipment to run at a standstill and pose a risk of electric shock. Do not turn on the device before completing the inspection.
1.2 Carrier and upper belt installation calibration
-Install the carrier tape roll on the feeding shaft, adjust the tightness of the shaft end retaining ring to ensure that there is no left or right deviation during the operation of the carrier tape; When threading, align the carrier tape with the detection position of the photoelectric sensor to ensure that the positioning hole of the carrier tape can be accurately recognized by the sensor.
-The upper cover tape needs to be installed on the receiving shaft or dedicated feeding rack. Adjust the tension controller to maintain the tension between the upper tape and the carrier tape at 5-10N before they are attached, to avoid over tightening and breaking the carrier tape or over loosening, which may cause wrinkles in the sealing.
1.3 Calibration of Optoelectronics and Knife Models
-Adjust the height of the photoelectric sensor to align with the carrier positioning hole, and adjust the sensitivity knob to the 70% -80% range to avoid accidental triggering; Manually jog the feeding to confirm that the photoelectric energy accurately detects the carrier positioning hole and triggers the feeding action.
-The cutting die needs to be adjusted according to the specifications of the carrier tape, and a feeler gauge should be used to confirm that the deviation between the die and the cutting reference line of the carrier tape is ≤ 0.2mm to avoid uneven cutting.
2. Core steps of linkage debugging
2.1 Feeding accuracy debugging
-Select the "manual feeding" mode, and the single feeding distance should match the specifications of the carrier tape. For example, the feeding distance of an 8mm carrier tape is 8mm. Adjust the feeding stepper motor parameters through the operation panel to control the feeding error within ± 0.1mm.
-Feed continuously for 10 times, use a vernier caliper to measure the actual length of each section of the carrier tape. If the error exceeds the range, recalibrate the position of the photoelectric sensor or adjust the pulse parameters of the stepper motor.
2.2 Sealing effect debugging
-Adjust the heat sealing temperature: Adjust according to the material of the upper cover tape. Set the temperature of the PET cover tape to 120-150 ℃ and the PS cover tape to 100-130 ℃. Adjust gradually through the temperature control knob and test the sealing strength.
-Adjust the sealing pressure: The pneumatic model adjusts the pressure to 0.2-0.3MPa through a pressure regulating valve to ensure that there are no curled edges or deep pressure marks between the carrier tape and the upper tape after sealing, which may cause the carrier tape to break.
-Testing method: Take 3 sets of sealed samples and manually pull the cover tape. If there is no detachment or deformation of the loaded tape, it is considered qualified.
2.3 Cutting accuracy debugging
-Select the "automatic cutting" mode, run the cutting action 10 times, measure the deviation between the finished product length and the design specifications, and the deviation should be ≤ 0.3mm.
-If there is a cutting deviation, adjust the locking bolt of the cutting guide rail and recalibrate the relative position between the cutting die and the carrier tape; If burrs appear, the worn cutting blade needs to be replaced.
3. Closing and Exception Handling
-After completing the debugging, it is necessary to run continuously for 30 minutes without load. After confirming that each link runs stably, actual materials should be added for mass production testing.
-Common exception handling: Check if there are burrs on the carrier tape and if the photoelectric sensor is blocked by dust when the feeding is stuck; If the sealing is not secure, adjust the temperature or tension again; If the cutting is uneven, the blade needs to be replaced or the position of the cutting die needs to be calibrated.
