The precautions for using the dispensing machine cover many aspects to ensure the accuracy, stability and safety of dispensing. Here are some key precautions:
1. Preparation before starting
Check the equipment: Before starting, check whether the dispensing machine is clean and whether there are any problems such as moisture, dust, etc. that directly affect the normal operation of the machine. At the same time, check whether the power supply and voltage are stable to ensure that the equipment is in good working condition.
Select glue: According to product requirements and process requirements, select suitable glue, and ensure that the glue quality meets the standards and has sufficient adhesion and durability. At the same time, understand the viscosity, curing time and other characteristics of the glue to match the machine parameters.
Wear protection: When working, you should wear protective clothing, gloves and other protective equipment, and try not to expose your skin to the outside to prevent glue from sticking to your skin or eyes.
2. Operation process
Avoid touching: In the working state, it is not allowed to touch the dispensing head, needle nozzle, guide chain and other moving parts with your hands to prevent accidental pinching.
Emergency stop: If special circumstances occur, such as machine failure, glue overflow, etc., you should immediately press the red emergency button on the front of the machine body to stop the machine immediately.
Parameter setting: According to the product dispensing graphics, compile a program and set appropriate dispensing speed, relative value of z-axis height increase, dispensing time and other parameters. At the same time, according to the viscosity of the glue and the working environment temperature, select the appropriate dispensing pressure and back pressure to ensure that the glue can flow out evenly and stably.
Real-time observation: During the dispensing process, it is necessary to always observe the outflow of glue and adjust the dispensing parameters according to the actual situation to achieve the best dispensing effect.
3. Maintenance and care
Cleaning and maintenance: After use, the glue residue on the dispensing machine should be cleaned in time to keep the equipment clean and tidy. At the same time, regularly clean the various components of the equipment, such as the gas system, transmission system, etc., to ensure that the equipment is unobstructed. When cleaning, pay special attention to cleaning the dispensing head and nozzle to prevent impurities from affecting the dispensing accuracy.
Regular inspection: Regularly perform safety performance tests on the dispensing machine, such as grounding resistance, to avoid unsafe phenomena such as leakage. At the same time, check whether the various components of the equipment are worn or damaged, and replace them in time if necessary.
Environmental control: The dispensing machine should be placed in a dry, ventilated, dust-free environment, avoiding direct sunlight and electromagnetic signal interference. At the same time, the ambient temperature and humidity should be controlled to ensure that the viscosity and fluidity of the glue meet the requirements.
IV. Other precautions
Glue storage: The glue should be stored in a suitable environment, such as epoxy glue should be stored in a refrigerator at 0-5℃. When using, it should be taken out in advance and the dispensing operation should be performed after reaching the working temperature.
Avoid overheating of glue: The glue may deteriorate if overheated, affecting its performance and effect. Therefore, it is necessary to ensure that the glue is used at an appropriate temperature.
Data recording: Record relevant data after each dispensing to facilitate subsequent analysis and improvement.
Training and specification: Operators need to receive training and strictly abide by the operating procedures to ensure correct operation.
