What to do if there is glue overflow during the dispensing process of the dispensing machine

Overflow refers to the excessive amount of glue on the screen, exceeding the planned usage, which affects the normal use of the screen or the next process. Since the root cause of screen glue overflow is now known, the problem of dealing with screen glue overflow lies in how to control the amount of glue. An automatic dispensing machine is an automated device that specifically controls glue and drips or applies it onto the surface of a product.

Nowadays, the application of automatic dispensing machines provides great support for industrial automation production. The use of automatic dispensing machines makes industrial automation production more powerful and faster. However, due to the fact that the automatic dispensing machine is composed of many precise components, it is inevitable that some malfunctions will occur during the dispensing process! So how to deal with the overflow problem of the automatic dispensing machine? Now let's listen to JEENOCE's sharing!

An automatic dispensing machine is an automated device that specifically controls glue and drips or applies it onto the surface of a product.

How to deal with the problem of glue overflow? What are the primary factors that affect the amount of adhesive to be confirmed?

1. Input air pressure value: 2. Needle diameter size; 3. The movement speed of the dispensing machine's cantilever; 4. If the glue is affected by temperature, calculate the preheating temperature time. If not, it does not need to be considered.

Automatic dispensing machines are equipped with a controllable input air pressure switch, which determines the amount of glue dispensed by controlling the air pressure value. If the air pressure is high, the amount of glue dispensed will increase within a certain period of time, which may be the cause of glue overflow. How to find the appropriate air pressure value? Generally speaking, a pressure value of 0.4-0.8MPa is the normal application scale for most adhesives. If encountering special adhesives, the manual dispensing function can be used to find the appropriate air pressure value to control the dispensing amount.

After the above adjustments, the overflow issue was greatly improved and basically met the customer's requirements during testing.

The diameter of the dispensing machine needle is generally at the level of physical knowledge, and the larger the hole, the greater the amount of glue produced. Simply replace the needle with the appropriate size based on the product to solve the problem of glue overflow.
