Description

Technical Field

[0001] The present invention relates to the technical field of measurement, and particularly to a method and device for measuring the separation temperature of welded components. Background Art

[0002] In some application scenarios, it is necessary to separate toxic and harmful welded components. When using conventional cutting methods for separation, the generated toxic and harmful flying chips can cause harm to the human body. If in a closed isolation space, cutting has the problem of being difficult to operate. Placing the welded component in a closed container for heating, at a high temperature state, creep fracture occurs at the weld to achieve the separation of the component. When using the heating separation method, the required separation temperatures for welded components of different metal materials are different. However, if the heating temperature is too low, the welded component cannot be separated; if the heating temperature is too high, it may cause serious deformation of the welded component. Therefore, the separation temperature of the welded component is crucial during the heating separation process.

[0003] It can be seen that in order to provide a data basis for the separation of other welded components of the same metal material, there is an urgent need to provide a method for measuring the separation temperature of welded components in a closed space. Summary of the Invention

Specific embodiments

[0033] The present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0034] Please refer to Figure 1 , an embodiment of the present invention provides a method for measuring the separation temperature of a welding member, including:

[0035] Step 100, controlling the heating temperature of the welding member by the heater in each temperature - rising time period; the control method is: starting from the initial temperature, increasing at a preset temperature interval;

[0036] Step 102, determining the deformation state of the welding member in each temperature - rising time period, and adjusting the temperature interval according to the deformation state;

[0037] Step 104, when it is monitored that the welding member is separated, determining the current heating temperature of the heater as the separation temperature of the welding member.

[0038] In an embodiment of the present invention, during the heating process of the welding member by the heater, by controlling the heating temperature of the heater in each temperature - rising time period, the heating temperature gradually increases from the initial temperature at a preset temperature interval, and by determining the deformation state of the welding member in each temperature - rising time period to adjust the temperature interval, and approaching the separation temperature by increasing the heating temperature. In this way, when it is monitored that the welding member is separated, it indicates that the current heating temperature reaches the separation temperature of the welding member, and the current heating temperature can be determined as the separation temperature. It can be seen that this solution can measure the separation temperature of the welding member.

[0039] Next, describe Figure 1 the execution manners of the following steps.

[0040] First, steps 100 "controlling the heating temperature of the welding member by the heater in each temperature - rising time period; the control method is: starting from the initial temperature, increasing at a preset temperature interval;" and 102 "determining the deformation state of the welding member in each temperature - rising time period, and adjusting the temperature interval according to the deformation state;" will be described simultaneously.

[0041] During the heating process, an initial temperature can be selected. Then, starting from this initial temperature, the heating temperature is gradually increased. By continuously increasing the heating temperature, the separation temperature of the welded component can be gradually approached, thereby enabling the separation temperature of the determined welded component to be more accurate.

[0042] In an embodiment of the present invention, the initial temperature can be set according to the melting point of the metal in the welded component. From experience, it is known that the separation temperature of the welded component is between 0.5 times and 0.95 times the melting point of the metal in the welded component. Therefore, the initial temperature can be set to be lower than 0.5 times the melting point of the metal in the welded component. For example, the initial temperature is set to 0.2 times the melting point of the metal in the welded component. Setting according to the melting point of the metal in the welded component can ensure that the initial temperature is not too high, so that the initial temperature is seriously deviated from or even far higher than the separation temperature, and can ensure that the initial temperature is not too low, resulting in a long measurement duration.

[0043] In an embodiment of the present invention, since the heating temperature needs to be gradually increased, the entire heating process can be divided into a plurality of continuous temperature-rising time periods. The heating temperature within the same temperature-rising time period is the same, and the heating temperatures within different temperature-rising time periods are different.

[0044] In an embodiment of the present invention, it can be determined whether the separation temperature is approaching by determining whether a phase change occurs in the welded component. If a phase change occurs in the welded component, it indicates that the current temperature is approaching the separation temperature. Whether a phase change occurs in the welded component needs to be determined according to the deformation state of the welded component within each temperature-rising time period.

[0045] In one implementation, the heating temperature is increased at the same temperature interval, and in a plurality of continuous temperature-rising time periods, each temperature-rising time period is equal;

[0046] Then, the determination method of the deformation state of the welded component within each temperature-rising time period may include:

[0047] Obtain the first expansion amount of the welded component within the current temperature-rising time period;

[0048] Determine the difference between the first expansion amount and the second expansion amount as the deformation state of the welded component within the current temperature-rising time period; the second expansion amount is the expansion amount of the welded component within the previous temperature-rising time period.

[0049] For example, the initial temperature is 200°C, the duration corresponding to each temperature increase period is 10 minutes, and the preset temperature interval is 50°C. Then, within the temperature increase period from 0 to 10 minutes, control the heating temperature of the heater to be 200°C; within the temperature increase period from 10 to 20 minutes, control the heating temperature of the heater to be 250°C; at the 10th minute, the expansion amount 1 of the welded component within the temperature increase period from 0 to 10 minutes can be obtained, and at the 20th minute, the expansion amount 2 of the welded component within the temperature increase period from 10 to 20 minutes can be obtained. The difference between the expansion amount 2 and the expansion amount 1 is determined as the deformation state within the temperature increase period from 10 to 20 minutes. It should be noted that for the temperature increase period from 0 to 10 minutes, since there is no previous temperature increase period, the deformation state of the first temperature increase period is not determined.

[0050] Specifically, when obtaining the first expansion amount of the welded component within the current temperature increase period, a distance measuring sensor set at a fixed position can be used to measure the distances between the welded component and the first time endpoint and the second time endpoint respectively within the current temperature increase period; the first expansion amount of the welded component within the current temperature increase period is determined according to the difference between the two distances. Among them, the first time endpoint and the second time endpoint form the two endpoints of the current temperature increase period.

[0051] For example, if the initial distance before heating is measured as d0, the distance at the 10th minute is d1, and the distance at the 20th minute is d2, then the expansion amount 1 is (d1 - d0), the expansion amount 2 is (d2 - d1), and the deformation state within the temperature increase period from 10 to 20 minutes is [(d2 - d1) - (d1 - d0)].

[0052] Using the distance measuring sensor to measure the distances corresponding to the two time endpoints respectively, and then using the difference between the two distances to determine the first expansion amount within the corresponding temperature increase period, the setting method is not only simple and convenient, but also the measurement result of the expansion amount is more accurate.

[0053] Furthermore, continuing with the above example, at the 20th minute, it is also necessary to determine whether to adjust the temperature interval according to the deformation state within the temperature increase period from 10 to 20 minutes. Specifically, it can be determined whether the deformation state is within the preset expansion amount. If it is determined that the deformation state is not within the preset expansion amount, the temperature interval is adjusted to be smaller; if it is determined that the deformation state is within the preset expansion amount, the temperature interval is not adjusted.

[0054] Assume that the deformation state within the temperature increase period from 10 to 20 minutes is within the preset expansion amount, then the temperature interval is not adjusted, and the heating temperature continues to increase according to the preset temperature interval. That is, within the temperature increase period from 20 to 30 minutes, control the heating temperature of the heater to be 300°C.

[0055] And so on. Assume that during the temperature-rising period from the 80th minute to the 90th minute (heating temperature is 600 °C), the deformation state is not within the preset expansion amount, which indicates that a phase change has occurred in the welded component. At this time, it is close to the separation temperature, and the temperature interval needs to be adjusted smaller. For example, if the temperature interval is adjusted to 20 °C, then the heating temperature of the heater can be controlled to be 620 °C at the 90th minute.

[0056] In the embodiment of the present invention, when it is determined that a phase change has occurred in the welded component, by adjusting the temperature interval smaller, the determination result of the separation temperature can be made more accurate.

[0057] Since the temperature interval is adjusted smaller, in order to enable the heating temperature to quickly reach the separation temperature, further, if it is determined that the deformation state is not within the preset expansion amount, the temperature-rising period is further adjusted shorter. For example, it is adjusted to 3 minutes, that is to say, during the subsequent heating process, the heating temperature is increased by 20 °C every 3 minutes.

[0058] It should be noted that after the temperature interval is adjusted once, during the subsequent heating process, it is possible not to continue to determine the deformation state to perform a secondary adjustment on the temperature interval, or it is also possible to continue to determine the deformation state of each temperature-rising period according to step 102, so as to further adjust the temperature interval smaller according to the deformation state, which can further improve the accuracy of the determination result of the separation temperature.

[0059] Then for step 104, when it is monitored that the welded component is separated, the current heating temperature of the heater is determined as the separation temperature of the welded component.

[0060] When the welded component is separated, it indicates that the separation temperature is reached at this time. Since the heating temperature rises gradually, therefore, the current heating temperature before heating can be directly determined as the separation temperature of the welded component.

[0061] Further, after the separation temperature of the welded component is determined, the heater can be controlled to stop heating, and the measurement process is completed.

[0062] Based on the method for measuring the separation temperature of the welded component provided in the above embodiment, the embodiment of the present invention further provides a device for measuring the separation temperature of the welded component. Please refer to Figure 2 and this device may include:

[0066] A separation temperature determination unit 204, configured to determine the current heating temperature of the heater as the separation temperature of the welded component when it is detected that the welded component is separated.

[0067] In an embodiment of the present invention, in a plurality of consecutive temperature increase time periods in which the heating temperature is increased at the same temperature interval, each temperature increase time period is equal;

[0068] The deformation determination unit is specifically configured to obtain a first expansion amount of the welded component during the current temperature increase time period; determine a difference between the first expansion amount and a second expansion amount as the deformation state of the welded component during the current temperature increase time period; the second expansion amount is the expansion amount of the welded component during the previous temperature increase time period.

[0069] In an embodiment of the present invention, when the deformation determination unit obtains the first expansion amount of the welded component during the current temperature increase time period, it specifically includes: using a distance measurement sensor disposed at a fixed position to measure the distances between the welded component at a first time endpoint and a second time endpoint during the current temperature increase time period respectively; determining the first expansion amount of the welded component during the current temperature increase time period according to the difference between the two distances.

[0070] In an embodiment of the present invention, the adjustment unit is specifically configured to determine whether the deformation state is within a preset expansion amount, and if it is determined that the deformation state is not within the preset expansion amount, then reduce the temperature interval.

[0071] In an embodiment of the present invention, the adjustment unit is further configured to, if it is determined that the deformation state is not within the preset expansion amount, further shorten the temperature increase time period.

[0072] Based on the measurement device for the separation temperature of the welded component provided in the above embodiments, an embodiment of the present invention further provides a measurement system for the separation temperature of the welded component.

[0075] Among them, the ranging sensor 3 can measure the distance from it to the welding component 7 in real time. Once the distance changes, it means that the welding component 7 expands during the heating process.

[0076] The first photoelectric sensor 1 and the second photoelectric sensor 5 normally receive the light source signal. When the light of the first photoelectric sensor 1 and the second photoelectric sensor 5 is blocked, it can be judged that the monitored component 7 separates and falls off.
