Description of the Invention: [Technical Field] The present invention relates to a dispensing unit with a bubble discharge, which can remove the bubble in the interior of the colloid and has the function of preventing the plunger from sliding in the colloid housing chamber It is stuck by the additive powder in the glue. [Prior Art] At present, the common dispensing device is mainly used for dispensing various electronic wafers, optical lenses, and LCDs and LEDs. With the advancement of technology, electronic components are getting smaller and smaller, so high precision is required. The glue device performs dispensing, which is roughly divided into a spray dispensing method and a needle dispensing method for coating at the most precise position. The above-mentioned conventional techniques are commonly used in the industry, for example, China Announcement No. M246506, No. 590049 U.S. Patent No. 6,371,339 and U.S. Patent No. 7,762,088. At present, the glue dispensing method of the dispensing device is generally used to push the glue out of the colloidal accommodation room. The control module controls the driving module to perform the most accurate movement of the plunger, and the glue is controlled by the change of the volume of the colloidal housing chamber. Machine output or pressure, in order to achieve good quality, must accurately control the dispensing pressure, = the amount of glue, etc. 'But the dispensing device replaces the storage cartridge will cause the residual air between the glue B to enter the dispensing device' There are often bubbles in the glue, which makes the amount of glue in the dispensing process different or even cause the production, no missing knees, so the product defect rate is improved; the material, the front rubber is often required to add fluorescent powder or various additives. When the powder is mixed, for example, the dispensing operation of D, the phosphor powder is mixed into the glue in the form of fine powder, which will penetrate into the slit between the plunger and the wall of the colloidal accommodation room, resulting in 201236766
