Pilot dispensing device, dispensing machine and dispensing method thereof

Abstract

The invention discloses a pilot dispensing device, a dispensing machine and a dispensing method of the dispensing machine. The dispensing device comprises a body, an adsorption platform and an annular groove; and the dispensing machine comprises a numerical control device, a dispensing system and the pilot dispensing device. The dispensing method comprises the following steps: receiving a pilot dispensing instruction; carrying out pilot dispensing and dropping glue to the adsorption platform by the dispensing system; receiving a dispensing instruction; and carrying out dispensing and dropping glue to a preset position of a workpiece until the dispensing process is finished by the dispensing system. According to the invention, adverse dispensing phenomena of bubble, excessive glue or insufficient glue and the like generated by glue addition and suction and the like of the dispensing machine are eliminated, thereby obtaining a better dispensing effect, ensuring the dispensing precision and efficiency and improving the quality of products; and in addition, the pilot dispensing process is automatically performed, so that the labor force is saved and the safety of an operation worker is improved. The pilot dispensing device, the dispensing machine and the dispensing method disclosed by the invention have the advantages that the structure is simple and the convenience in operation is realized.

Description

technical field [0001] The invention relates to the field of glue dispensing, in particular to a pilot glue dispensing device, a glue dispensing machine and a glue dispensing method. Background technique [0002] Glue dispensing machine, also known as glue applicator, glue dropping machine, gluing machine, etc., is an automatic machine that controls fluid, drips and coats the fluid on the surface of the product or inside the product. The glue dispenser is mainly used for accurate pointing, injecting, coating, and dripping of glue, paint and other liquids in the product process to the precise position of each product, and can be used to achieve dots, lines, circles or arcs. By sending compressed air into the syringe or glue bottle, the glue dispenser presses the glue into the feed tube connected to the piston chamber, and uses the pressure to perform the glue dispensing operation. When the piston is on the upstroke, the piston chamber will be filled with glue; when the pisto...

Problems solved by technology

During the dispensing process, the glue storage container of the dispenser needs to add glue or pump glue to meet the continuous progress of the dispensing process. However, after adding glue, the glue storage container of the glue dispenser or the glue used for dispensing Bubbles will appear at the front end of the dispensing valve body. After the glue is pumped, the first product to be glued is prone to excessive glue or less glue, which will eventually lead to inconsistent dispensing volume of the product and unqualified product quality.
