A sealing method for reducing the sealing rejection rate of glass thermometers

Abstract

The invention discloses a sealing method for reducing the sealing waste rate of glass thermometers, which comprises the following steps: (1) sorting the glass thermometers according to the lengths of the glass thermometers; (2) sealing the sorted glass shells with an automatic sealing machine according to the order of sorting , and count the yield rate, draw the yield curve, and determine the actual lower limit value X of the length of the glass shell sealed by the automatic sealing machine 1 ; (3) Same as step (2), determine the actual lower limit value X of the length of the artificially sealed glass shell 2 , so as to judge that it meets the category I of automatic sealing machine and the category II of manual sealing; (4) classify those that are not included in category I and category II as useless waste category III; (5) according to category I, Category II corresponds to the length and classifies the glass shells of thermometers before sealing, and then seals them with a dynamic sealing machine and manually. The invention can reduce the reject rate of sealing, improve the sealing efficiency of the automatic sealing machine, and reduce the waste of waste products on processes and materials.

Description

technical field [0001] The invention relates to the production and processing of glass thermometers, in particular to a sealing method for reducing the rate of defective sealing of glass thermometers. Background technique [0002] During the production process of the internal standard thermometer, a certain percentage of the top of the jacket material will be damaged, which will lead to the top of the jacket being irregular and the effective length of the seal of the jacket will be reduced. When sealing, if the distance between the sealing place and the top is very small, it is easy to cause unqualified products such as cold burst or small size during the sealing process, which will affect the processing efficiency of the sealing of the internal standard thermometer, and also affect the overall pass rate of the product. [0003] However, there are many semi-finished products with damaged tops above, and those with longer lengths can be sealed with an automatic sealing machin...

AI Technical Summary

Problems solved by technology

[0002] During the production process of the internal standard thermometer, a certain percentage of the top of the jacket material will be damaged, which will lead to the top of the jacket being irregular and the effective length of the seal of the jacket will be reduced. When sealing, if the distance between the sealing part and the top is very small, it is easy to cause unqualified products such as cold burst or small size during the sealing process, which will affect the sealing processing efficiency of the internal standard thermometer and also affect the overall pass rate of the product

[0003] However, there are many semi-finished products with damaged tops above, and those with longer lengths can be sealed with an automatic sealing machine after pasting the internal standard, and the length can meet the length requirements of the thermometer, but the damaged ends are closer to the sealing place, use The seal of the automatic sealing machine is easy to be cold and broken and becomes a waste product. If the length is small and cannot meet the sealing needs, it will be recycled as a production waste product, and it will not be processed in a waste process.
