A dispensing device for diode packaging

Abstract

The present invention discloses a dispensing device for diode packaging. Before dispensing the diode packaging, the raw materials of the dispensing glue can be divided into three parts by arranging the paddle plates in a vertical state, thereby avoiding that the raw materials of the dispensing glue can be stored for a longer time when the dispensing process is not needed. When the diode packaging needs to be dispensed, the three paddle plates rotate around the paddle plate connecting rod to mix the dispensing raw materials, and rotate around the telescopic cylinder to stir the raw materials, so that the raw materials can be fully stirred. The outer sides of the paddle plates are flexible rubber. When the three paddle plates rotate around the telescopic cylinder, the flexible rubber on the outer sides of the paddle plates scrapes the inner wall of the glue barrel, so that the raw materials adhered to the inner wall of the glue barrel during the stirring process are scraped off, so that each raw material is mixed more fully. The telescopic cylinder extends to form negative pressure, and the glue enters the telescopic cylinder. The telescopic cylinder is compressed and the glue is pumped into the glue gun. The pressure of the pressure pump itself plus the pressure of the telescopic cylinder can make the glue that becomes viscous later more easily discharged from the glue gun, thereby reducing the error of discharging the glue.

The main difficulty is controlling the amount of dispensing, because the glue will thicken during use. After thickening, there is a large gap between the amount of glue discharged by the glue gun and the theoretical value, resulting in a decrease in the diode yield. Summary of the Invention

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. It is obvious that the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] See also Figure 1-6 , this embodiment provides the following embodiments:

[0023] Example 1

[0024] When dispensing glue for diode packaging, the interior of the glue barrel 31 is divided into three parts by the vertical dial plate 35, and each part is loaded with three raw materials for dispensing glue, and the components do not react with each other. When the production line needs to perform a dispensing process, the upper telescopic cylinder 44 drives the adapter plate 32 to move downward, and the adapter plate 32 drives the second connecting rod 34 to move downward through the first connecting rod 33. The downward-moving second connecting rod 34 drives the dial plate 35 to deflect through the fisheye joint with the middle part of the dial plate 35. At this time, the glue barrel 31 is divided into three independent parts by the dial plate 35, which are interconnected, and the three components of raw materials are mixed. As the motor 42 rotates, the telescopic cylinder composed of the upper telescopic cylinder 44 and the lower telescopic cylinder 36 is driven to rotate. The three raw materials in the rubber barrel 31 are fully mixed, and the motor 42 drives the telescopic cylinder to rotate. The telescopic cylinder drives the three paddles 35 to rotate around the telescopic cylinder through the connecting sleeve 40 and the paddle connecting rod 41. Each paddle 35 moves up and down through the adapter plate 32 and transmits power through the first connecting rod 33 and the second connecting rod 34, thereby driving the paddle 35 to rotate around the paddle connecting rod 41. The three raw materials in the rubber barrel 31 are mixed more evenly. Because the outer side of the paddle 35 is flexible rubber, when the three paddles 35 rotate around the telescopic cylinder, the flexible rubber on the outer side of the paddle 35 will scrape the inner wall of the rubber barrel 31, so that the raw materials adhered to the inner wall of the rubber barrel 31 during the mixing process are scraped off, so that each raw material is mixed more fully.

[0025] Example 2

[0026] When the raw materials in the glue barrel 31 are fully mixed, the diode 13 on the assembly line 12 is transported to the glue dispensing station. At this time, the upper telescopic cylinder 44 of the telescopic cylinder extends out of the telescopic cylinder to form a negative pressure. At this time, the material blocking plate 38 is separated from the inner wall of the lower telescopic cylinder 36, and the glue inlet 37 is connected to the inside of the telescopic cylinder. The finished glue made after mixing enters the telescopic cylinder through the glue inlet 37, and the telescopic cylinder contracts. At this time, the material blocking plate 38 is pressurized and thus adheres to the inner wall of the lower telescopic cylinder 36. The telescopic cylinder is compressed to pump out the glue, and the glue is pressurized by the pressure pump 39 to pass through the glue delivery pipe 23 to the glue gun 21 for dispensing the diode 13.

Any equivalent structure or equivalent process transformation made using the contents of the present invention's description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
