Description

Technical Field

[0001] The utility model relates to the technical field of film loading machines, in particular to a glue dispensing rod device with a fixing device for reducing the glue squeezing amount of a film loading machine. Background Art

[0002] The existing HX2100 film loading equipment has a relatively long and curved dispensing rod. The silver glue extrusion of the film bonding material is piston extrusion. After the silver glue in the hose is used up, a large amount of silver glue will remain in the dispensing rod and cannot be used. When replacing another silver glue after the operation, this part needs to be squeezed out and wasted when the air in the hose is exhausted. The dispensing shortcomings of the existing HX2100 film loading equipment are mainly reflected in the following: 1. The dispensing rod of the HX2100 equipment is long and has a large bending angle, which is not conducive to excluding the air in the silver glue needle tube. There is a risk of increasing the number of alarms for large glue and small glue during the operation. 2. The design of the existing dispensing rod of HX2100 is relatively long, and the silver glue needle tube is elongated from the dispensing position. After the silver glue of the film bonding material is used up, a large amount of silver glue will remain in the dispensing rod, which cannot be effectively used. After replacing another tube of silver glue, it is necessary to remove the air and moisture in the silver glue hose. This part of the silver glue will be squeezed out and wasted at the same time, resulting in a large waste of material costs. The same personnel squeezed glue on different types of equipment, P value = 0 < 0.05. According to the interval graph and single value graph of the squeezed glue amount, it can be seen that the squeezed glue amount of different types of equipment has significant differences. Among them, the HX2100 equipment squeezed more glue, and the average squeezed glue amount of HX2100 was 0.92g, and its squeezed glue loss was 2 to 4 times that of other equipment models.

[0003] Redesigning the dispensing rod, shortening the length of the dispensing rod of the HX2100 device, and adding a fixing device for the dispensing rod and the silver glue needle can effectively shorten the length of the dispensing rod, reduce the silver glue residue in the dispensing rod, which causes the abnormality of large and small glue, and the waste of silver glue caused by squeezing glue.
