DETAILED DESCRIPTION

[0025] The specific implementation of the utility model is further explained in detail below. Figures 1-7 The specific implementation of the utility model is further explained in detail below.

[0026] The utility model discloses a machine table 3, machine table 3 is the basic support structure of entire welding equipment, its design is stable and convenient operation, can place the article required for production inside, the front side of machine table 3 is equipped with high frequency heating all -in -one 1, high frequency heating all -in -one 1 is responsible for generating high frequency current, provides the necessary energy for the welding process, the design of high frequency heating all -in -one 1 has adopted advanced cooling system, ensures long -time stable operation, the top outer periphery of machine table 3 is equipped with frame 4, the outside of frame 4 is equipped with the fender, is used to support and protect the each component of welding area, the outside of frame 4 is covered with the fender, the fender is made of high temperature -resistant, prevents the material of splashing and makes, effectively prevents the harm of spark and splashing thing generated in the welding process to equipment and operating personnel, the top of machine table 3 is equipped with operating platform 8, the top of operating platform 8 is equipped with three -axis positioning assembly, this assembly is driven by servo motor of X axis, Y axis and Z axis three directions, realizes high -precision positioning through closed -loop control system, the left side of three -axis positioning assembly is equipped with right angle frame 13, the inside of right angle frame 13 is equipped with high frequency coaxial transformer 15, the rear side of high frequency coaxial transformer 15 is equipped with high frequency induction heating coil 16, high frequency coaxial transformer 15 converts the high frequency current generated by high frequency heating host into the high frequency induction current suitable for welding, high frequency induction heating coil 16 is located at the rear side of high frequency coaxial transformer 15, and energy is transferred to the workpiece to be welded through the non -contact heating mode, and this design reduces energy loss and improves welding efficiency, the top rear side of operating platform 8 is equipped with the locating plate 7, the top of locating plate 7 is equipped with the fixture 14, the top of locating plate 7 is equipped with a plurality of through -holes, can be replaced and adjusted according to the shape and size of the workpiece to be welded, improve the versatility and flexibility of the welding machine. The material of fixture 14 is made of high-strength, high-temperature-resistant material to ensure stable clamping force during welding.

[0027] The right side of right angle frame 13 is provided with an infrared probe 17, and the infrared probe 17 is used for real-time monitoring of temperature change of a welding position. The infrared probe 17 quickly and accurately acquires temperature information of the welding position through a non-contact measurement mode, and transmits the data to a control system. The control system adjusts the welding process in real time according to the temperature information to ensure stable and reliable welding quality, and then adjusts the different modes of the corresponding adjusting device.

[0028] In the temperature control mode, the control system automatically adjusts the output power of the high-frequency heating power supply according to the preset temperature range to realize accurate temperature control. When the infrared probe 17 detects that the temperature inside the induction coil is lower than the set value, the control system will increase the output power to increase the heating speed. Conversely, when the temperature exceeds the set value, the output power will be reduced to avoid overheating. In this mode, the system continuously monitors the temperature and feeds back the adjustment to generate a smooth heating curve, ensuring that the heating process is both fast and stable. At the same time, the system also has a self-adaptive learning function, which can continuously optimize the temperature control strategy according to historical heating data to improve the heating efficiency.

[0029] The time mode pays more attention to the accurate control of the heating time. In this mode, the operator only needs to set the required heating time, and the control system will start the high-frequency heating power supply and heat according to the set time. Regardless of the temperature change inside the induction coil, the system will not actively adjust the output power until the set heating time is reached and automatically stopped. This mode is suitable for application scenarios that have strict requirements on heating time but do not require high precision temperature control.

[0030] The temperature + time mixed control mode combines the advantages of the previous two modes, ensuring accurate control of the heating temperature and strict management of the heating time. In this mode, the control system will adjust the output power of the high-frequency heating power supply and the heating time according to the preset temperature range and time limit. When the temperature reaches the set range, even if the heating time has not arrived, the system will automatically reduce the output power or stop heating to avoid overheating. Similarly, when the heating time reaches the set value, even if the temperature has not reached the preset range, the system will stop heating to ensure the safety and stability of the heating process.

In order to enhance the safety of the equipment and prevent the user from accidentally putting his hand into the device during use, causing accidents, two grating sensors 6 are specially arranged on the rear side of the frame 4, which are symmetrically arranged left and right, forming a safety monitoring area. The two grating sensors 6 are configured to form a safety light curtain. When they are working normally, they will emit infrared or visible light beams, which form a continuous and invisible barrier in space. When any object (such as a hand) passes through this light curtain, it will break at least one light beam, triggering the response of the sensor. When the light beam of the grating sensor 6 is broken, the photoelectric conversion element (such as a photodiode) will immediately convert the change of the light signal into an electrical signal, and the control device will stop working to prevent harm to the user.

[0032] The top rear side of the frame 4 is provided with an operation screen 5, which not only provides an intuitive and convenient interactive interface for the user, but also integrates the functions of viewing all information and controlling all instructions, providing a powerful and convenient interactive platform.
