Description

Technical Field

[0001] The present invention relates to the technical field of glue dispensing equipment, and more specifically, to a glue dispensing equipment for producing lighting lamps. Background Art

[0002] In today's daily life, lighting equipment is everywhere. They provide us with light and make the night as bright as day. Among these lighting equipment, lighting lamps are undoubtedly one of the most widely used and common equipment. However, behind these seemingly simple lighting lamps, there are complex production processes and sophisticated manufacturing technologies. Among them, the dispensing process of the lamp tube is one of the most important links. In order to achieve precise coating of specific areas inside or outside the lamp tube and ensure the stability and performance of the lighting lamp, the dispensing machine came into being. The dispensing machine is applied drop by drop on the surface or inside of the product. In the production process of lighting lamps, the dispensing machine plays an irreplaceable role.

[0003] Existing dispensing equipment is generally driven by electricity, and the dispensing route is usually linear or spaced dot-type. When using the spaced dot-type dispensing route, the dispensing head only applies dots at preset positions, which will result in the area between the dispensing points not being covered with glue, the so-called "less glue left". When the next step of pasting is performed, these areas without glue may cause uneven glue coating. If the interval between the dispensing points is too large or the amount of glue dispensed is insufficient, then during pasting, these areas without glue may form "holes" or "gaps", affecting the tightness and firmness of the pasting. In addition, if the shape or size of the dispensing points is inconsistent, it will also lead to uneven coating. For the linear dispensing route, although it is carried out along a straight line, It can be coated, but it may also face the problem of less glue remaining, which is usually caused by the following reasons: if the glue flow is not set properly or the glue supply is insufficient, the straight-line glue line may be thinner or sparse, resulting in less glue remaining; if the coating speed is too fast, the glue may not be evenly distributed on the coating path, resulting in some areas without glue; wear or damage to the coating head may also cause uneven distribution of glue during the coating process, resulting in less glue remaining; regardless of whether it is an interval dot-type or a linear dot-type glue route, less glue remaining will result in uneven glue coating during the next step of pasting, which may affect the bonding quality of the product, such as reducing the bonding strength and affecting the flatness of the bonding surface. Therefore, it needs to be improved and optimized. Summary of the invention
