[0023] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0024] like Figure 1 As shown, the utility model provides a real-time monitoring device for spring heat treatment, comprising a current acquisition module, a main control module and an alarm.

[0025] Among them, the current acquisition module is connected to the spring heat treatment equipment and is used to collect real-time current data of the spring heat treatment equipment.

[0026] The main control module is electrically connected to the current acquisition module, the spring heat treatment equipment, and the alarm. The main control module is used to obtain real-time current data through the current acquisition module, and to match and compare the current data preset by its system, and when the real-time current data in the comparison result is greater than the preset current data, the alarm B is controlled to alarm and the spring heat treatment equipment is controlled to stop.

[0027] Preferably, for example, a comparator is provided inside the main control module to compare the collected real-time current data with the preset current data to determine the magnitude of the current.

[0028] More preferably, the utility model also provides another specific circuit implementation, such as Figure 2 As shown, the main control module includes: a rectifier bridge U, a solid-state relay KQ, a first switch S, a first electromagnetic relay KM and a second electromagnetic relay KT.

[0029] The first electromagnetic relay KM is provided with a first normally closed contact KM11, and the second electromagnetic relay KT is provided with a second normally open contact KT21 and a second normally open contact KT22.

[0030] The current acquisition module is electrically connected to the input end of the rectifier bridge U, and the output end of the rectifier bridge U is electrically connected to the input end of the solid-state relay KQ. The output end of the solid-state relay KQ is also connected to the first switch S for controlling the opening and closing of the first switch S.

[0031] When the real-time current data collected by the current collection module is greater than the preset current data, the solid-state relay KQ controls the first switch S to open.

[0032] The first end of the first electromagnetic relay KM is connected to the positive pole of the power supply (DC+24V), and the second end is connected to the negative pole of the power supply (DC-24V) through the first switch. That is, when the first switch S is opened, the first electromagnetic relay KM loses power; on the contrary, when the first switch S is closed, the first electromagnetic relay KM is energized.

[0033] The first end of the second electromagnetic relay KT is connected to the positive pole of the power supply through the first normally closed contact KT11 of the first electromagnetic relay KT, and the second end is connected to the negative pole of the power supply. That is, when the first electromagnetic relay KM loses power, the first normally closed contact KM11 of the first electromagnetic relay KM is closed, and the second electromagnetic relay KT is energized; on the contrary, when the first electromagnetic relay KM is energized, the first normally closed contact KM11 of the first electromagnetic relay KM is opened, and the second electromagnetic relay KT loses power.

[0034] One end of the second normally open contact KT21 of the second electromagnetic relay KT is connected to the positive pole of the power supply, and the other end is connected to the negative pole of the power supply through the alarm B. That is, when the second electromagnetic relay KT is powered, the second normally open contact KT21 of the second electromagnetic relay KT is closed, and the alarm B is powered on to alarm; on the contrary, when the second electromagnetic relay KT is de-energized, the second normally open contact KT21 of the second electromagnetic relay KT is opened, and the alarm B is powered off and does not alarm.

[0035] Specifically, when the real-time current data collected by the current acquisition module is greater than the preset current data, the solid-state relay KQ controls the first switch S to open, the first electromagnetic relay KM loses power, the first normally closed contact KM11 of the first electromagnetic relay KM closes, the second electromagnetic relay KT is energized, the second normally open contact KT21 of the second electromagnetic relay KT closes, and the alarm B is powered on to alarm. That is, when the current of the heat treatment equipment exceeds the set value, the solid-state relay KQ, the first switch S, the first electromagnetic relay KM and the second electromagnetic relay KT cooperate to control the alarm B to be powered on to alarm, thereby realizing real-time monitoring of the current of the heat treatment equipment.

[0036] Similarly, the second normally open contact KT22 of the second electromagnetic relay KT is also electrically connected to the controller of the heat treatment equipment, and is used to send a shutdown command to the controller of the heat treatment equipment. When the second electromagnetic relay KT is energized, the second normally open contact KT22 of the second electromagnetic relay KT is closed, and after the controller of the heat treatment equipment receives the shutdown command, it controls the heat treatment equipment to shut down; on the contrary, when the second electromagnetic relay KT loses power, the second normally open contact KT22 of the second electromagnetic relay KT is opened, and the controller of the heat treatment equipment cannot receive the shutdown command and will not control the heat treatment equipment to shut down.

[0037] The utility model monitors the real-time current of the heat treatment equipment during processing operation, and when the real-time current is too large, controls the heat treatment equipment to stop while giving an alarm through the cooperation of the solid-state relay KQ, the first switch S, the first electromagnetic relay KM, and the second electromagnetic relay KT, thereby achieving real-time monitoring of the current of the heat treatment equipment, so as to solve the problem in the prior art that the overall supporting force of the final spring mattress results in serious uneven or uneven rebound due to the excessive current of the heat treatment equipment.

[0038] More preferably, the current acquisition module in the utility model adopts a current transformer L. The current transformer L is connected to the heat treatment equipment, and can realize the collection of real-time current data of the heat treatment equipment during processing. When the utility model collects current from the heat treatment equipment, it does not make any improvements to the internal structure of the heat treatment equipment, and can be realized by adopting an external design, which is suitable for any heat treatment equipment and has a wider application.

[0039] Preferably, the alarm B is an audible and visual alarm. The solid-state relay KQ is an optically coupled solid-state relay.

[0040] More preferably, the rectifier bridge U is provided with a first input terminal, a second input terminal, a first output terminal and a second output terminal. One end of the current transformer L is electrically connected to the first input terminal of the rectifier bridge U, and the other end is electrically connected to the second input terminal of the rectifier bridge U.

[0041] The first output end of the rectifier bridge U is electrically connected to the positive pole of the solid-state relay KQ, and the second output end is electrically connected to the negative pole of the solid-state relay KQ.

[0042] Preferably, the utility model further includes an electrolytic capacitor C. The electrolytic capacitor C is connected in parallel to the first output terminal and the second output terminal of the rectifier bridge U. That is, one end of the electrolytic capacitor C is electrically connected to the first output terminal of the rectifier bridge U, and the other end is electrically connected to the second output terminal of the rectifier bridge U.

[0043] The utility model realizes real-time monitoring of the current of the automatic spring heat treatment equipment through the coordinated use of the current transformer L, the rectifier bridge U, the relay and the alarm B. Once the current of the spring heat treatment equipment is less than the set value, an alarm will be triggered and the spring heat treatment equipment will be controlled to shut down. The utility model can be applied to the current monitoring of the common heat treatment equipment on the market, has wide applicability, and has the characteristics of simple structure and convenient operation.

[0044] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
