Assembling and testing equipment and technology of dial thermometer automatic production line

Abstract

The invention discloses assembly and testing equipment for an automatic production line of dial-type thermometers, which belongs to the technical field of dial-type thermometer production, and includes a mechanical grabbing mechanism, a casing welding and glue coating device, a pressing and firming device, a detection and correction device and eight transportation devices. The welding and gluing device is arranged on the top of the assembly platform. The shell welding and gluing device includes a welding mechanism and a gluing mechanism. The mechanism is arranged on the fixed table and the upper output end is located on the tooling of the rotary table. The invention can realize the automatic assembly and detection of the dial-type thermometer, the process design is ingenious, and the connection between the processes is smooth. Compared with manual work, the production efficiency is increased by 8-10 times, and a production line can save 5-6 workers, which has significant economic value. .

Description

technical field [0001] The invention relates to the technical field of assembly and detection of dial thermometers, in particular to the assembly and detection equipment and technology of the automatic production line of dial thermometers. Background technique [0002] The main features of the dial thermometer are on-site temperature display, which is intuitive and convenient; safe and reliable, and has a long service life; various structural forms to meet different requirements. The structure of the dial thermometer is as attached Figure 14 and 15 As shown, the working principle is to use the thermal expansion and contraction of the metal wire to drive the pointer to rotate, so as to achieve the purpose of temperature measurement. [0003] At present, the dial thermometer can only be assembled, produced, tested and corrected by using a set of equipment for each process, which occupies a large area, and the corresponding noise is also large. There are many types of equipme...

Problems solved by technology

Because the glass surface is often in the form of a convex lens for magnified display, the glass surface is convex. Such a production pressing process can easily break the glass piece or cause scratches, which will affect the use, and the pressing force is not easy to control. Even if the pressure is in place, there may be air leakage, and after long-term use or high-temperature use, the fixed O-ring is prone to aging, fracture or deformation shrinkage. At the same time, the welding between the sleeve component and the base is not comprehensive and the rigidity is poor. , poor sealing, easy to break

[0005] All of the above will lead to the air intake inside the dial thermometer, and the sealing performance will be deteriorated, and the dial thermometer with poor sealing will easily generate water vapor in a humid and high temperature environment, which will affect the observation, and the temperature water vapor and oxygen in the air will also corrode the dial thermometer. The uranium wire in the thermometer makes the nature and temperature of the uranium wire itself change continuously, thereby reducing the accuracy of the measurement data of the dial thermometer and interfering with the zero calibration value of the dial thermometer, so that the dial thermometer needs to be constantly checked and calibration, reducing the service life of the dial thermometer
