Long time production can accumulate certain experience for product speed and solve production problems for customers. In the process of using the dispenser, there will be drawing, blocking the rubber outlet, or uneven rubber outlet. pinsu technology will explain how to improve the dispensing quality of the automatic dispenser?





The first is the difference between glue and the choice of the corresponding glue outlet, which is also very learned.



1. Instant glue: for water-based instant glue, use safety piston and Teflon lined metal needle; for thick instant glue, use tapered inclined needle;



2. UV glue: use amber syringe, white piston and inclined needle (UV protection). If other kinds of needle are used, the UV protection needle can be customized;



3. Light curing adhesive: use black opaque syringe to avoid light sensitivity;



4. Anaerobic rubber: 10cc syringe and white PE universal piston are used;



5. Sealant and paste fluid: if the white piston rebounds seriously, please use the safe movable type and oblique needle; for the adjustment of various parameters, the method of point and surface shall be followed, and the change of any parameter will affect other aspects, and at the same time, the defect





Secondly, the size and stability of dispensing pressure will also affect the dispensing effect. After determining the proper dispensing nozzle with the contact surface, it is necessary to find the appropriate air pressure through many attempts. If the air pressure is too large, it will cause glue overflow, too much glue, and too small pressure will lead to intermittent dispensing, poor dispensing effect, and unstable air pressure will also cause uneven dispensing, Therefore, the factory needs to maintain a stable and appropriate air pressure to ensure a good glue out effect.



Thirdly, the dispensing effect is not only affected by the control effect of the dispensing machine's own glue valve, but also by the viscosity of the glue. Viscosity is large, glue out is slow, easy to draw, viscosity is too low, liquidity is strong, glue control becomes difficult and easy to drip, so choosing the appropriate viscosity glue can also effectively solve the problem of dispensing efficiency. In addition, the packaged glue must not have bubbles, which will cause partial glue breaking and no glue. The glue or hose should be properly discharged every time when replacing the glue or hose, so as to eliminate the air in the cavity and ensure the smooth glue delivery.




Fourth, when adjusting the dispensing parameters and editing the dispensing trajectory, choosing the right needle and adjusting the appropriate distance between the needle and the contact surface will also affect the dispensing effect. Through many attempts, better position parameters can be obtained. Before each work, calibrate the distance between the needle and the working surface, pay attention to observe the dispensing effect under different parameters, summarize experience, and moderate fine-tuning.



Fifthly, for the use of the automatic dispensing machine, the workshop should arrange special personnel to study the operation and maintenance of the machine, and the special personnel should be specially assigned for the special machine, and ensure that two or more personnel understand the operation of the machine at the same time, so as to prevent one of them from leaving the job, and other people can immediately take the post, so as to reduce the impact caused by the personnel flow.





No matter the automatic dispensing machine or other automatic equipment, each factory hopes to achieve better use effect and create greater value after putting into operation, so everyone should learn and master the operation methods of the equipment, and do a good job in maintenance.
