Description

Die-casting thermal image vision device

Technical Field

The utility model relates to the technical field of industrial production casting, in particular to a die-casting thermal image vision device.

Background

In product development, product testing and product maintenance, thermal testing of products and searching for thermal defects are vital links, and in thermal testing of products, conventional testing tools such as a temperature box, a multipoint thermometer (thermocouple), a point thermometer and the like are commonly used. The conventional temperature measuring modes of the multipoint thermometer and the like have some insurmountable limitations, such as deviation of a characteristic curve of a thermocouple, electromagnetic interference, temperature limitation of adhesive, adhesive point error, necessity of contacting an object to be measured and the like. The contact type temperature measurement is characterized in that the temperature sensing element is directly contacted with the measured object, the temperature sensing element and the measured object are subjected to sufficient heat exchange, and finally the heat balance is achieved, at the moment, the temperature of the temperature sensing element is necessarily equal to the temperature of the measured object, and the display value of the thermometer is the temperature of the measured object. According to the principle of temperature measurement conversion, contact temperature measurement can be divided into various forms such as expansion type, thermal resistance type, thermoelectric type and the like. The following are examples of thermoelectric:

the thermoelectric method adopts a thermocouple to measure the temperature field, and fig. 1 is a schematic diagram of the thermocouple to measure the liquid level of high-temperature molten metal. A series of measuring points are selected on the container wall, thermocouples are arranged, the output of the thermocouples at each measuring point is recorded, a temperature-potential distribution curve shown in figure 2 is obtained, the temperature mutation is reflected between the 7 th measuring point and the 8 th measuring point on the curve, and therefore the liquid level is between the 7 th measuring point and the 8 th measuring point.

The thermocouple is used for measuring the liquid level by a relatively rough measuring method, the accuracy is generally not high, and the accuracy is related to the distribution and installation conditions of the thermocouples. The distance between the thermocouples is properly reduced, and the measuring points are increased, so that the resolution and the measuring precision of the metal liquid level measurement can be improved. In addition, the contact point between the working end of the thermocouple and the container is thin and firm, so that the thermocouple can be wire-welded on the container wall, and the container wall serves as the other pole of the thermocouple.

Because the temperature sensing element needs to be in direct contact with the measured medium, the thermal balance state of the measured medium can be influenced, and the poor contact can increase the temperature measurement error, and the performance and the service life of the temperature sensing element can be seriously influenced if the measured medium has corrosiveness or the temperature is too high. Meanwhile, production is required to be stopped when the temperature sensing element is installed, and production efficiency is seriously affected.
