The feeding module 2 is fixedly mounted on the frame 1. The feeding module 2 is provided with a sub-product positioning carrier 6 for horizontally stopping and positioning the sub-product 7. The heating module 4 comprises a heating device and a sub-product heating positioning device. The heating device is fixedly mounted on the frame 1. The sub-product heating positioning device is mounted on the frame 1. The sub-product heating positioning device can stop and position the sub-product 7. The heating device can heat the sub-product 7. The fixed end of the transport module 3 is fixedly positioned on the frame 1. The moving end of the transport module 3 is provided with a clamping mechanism 19. The clamping mechanism 19 can clamp and release the sub-product 7. The clamping mechanism 19 on the moving end of the transport module 3 can operate between the sub-product positioning carrier 6 of the feeding module 2 and the sub-product heating positioning device of the heating module 4. The control system 5 controls the movement of the moving end of the transport module 3 and the clamping mechanism 19 and the start and stop of the heating device of the heating module 4.

[0021] The loading and positioning of the sub-product 7 is achieved by the sub-positioning carrier 6 on the loading module 2, which is convenient for workers to load. After loading, the sub-product 7 is transported to the heating module 4 by the transporting module 3, and the sub-product 7 is positioned on the sub-heating positioning device in the heating module 4 for precise heating. After the heating is completed, the transporting module 3 moves it out of the heating module 4. The entire work does not require worker operation, saving labor, improving production efficiency and heating accuracy, avoiding burns caused by workers during transportation, and improving operational safety. The sub-positioning carrier 6 and the sub-heating positioning device can be a planar structure, and a positioning pin matching the positioning hole at the lower end of the sub-product 7 is provided on the planar structure to realize the positioning of the sub-product 7. The positioning pins are preferably arranged in an asymmetrical state to achieve the effect of fool-proof loading.

[0022] The frame 1 is provided with a horizontal surface 8 and an outer cover 9. The loading module 2 and the transport module 3 are both mounted on the horizontal surface 8. The outer cover 9 is fixedly provided above the horizontal surface 8. The transport module 3 and the heating module 4 are covered on the inner side of the outer cover 9. The horizontal surface 8 and the outer cover 9 protect the heating module 4 and the transport module 3 to prevent accidental injury to workers.

[0023] The loading module 2 includes a linear guide 10, a slider 11 and a horizontal drive device 12. The linear guide 10 is fixedly installed on the horizontal platform 8. An opening structure is formed on one side wall of the outer cover 9. One end of the linear guide 10 is located on the inner side of the outer cover 9, and the other end of the linear guide 10 extends to the outside of the outer cover 9 through the opening structure on one side of the outer cover 9. The slider 11 is installed on the linear guide 10 so as to be able to slide along the extension direction of the linear guide 10. The horizontal drive device 12 drives the slider 11 to slide back and forth. The insert positioning carrier 6 is fixedly installed on the slider 11. Through the linear guide 10 and the slider 11, the worker loading the material is located outside the outer cover 9, and then the slider 11 automatically sends the insert product 7 into the inner part of the outer cover 9 for transportation and heating. The whole process can completely avoid manual contact with the transportation module 3 and the heating module 4, avoiding worker injuries.

[0024] A first product sensor 13 is also provided on the horizontal surface 8. This sensor can sense when the slider 11 or the positioning carrier 6 reaches a designated position at one end of the linear guide 10. This sensor is electrically connected to the control system 5, which controls the start, stop, and forward and reverse motion of the horizontal drive 12. When the product 7 is carried by the slider 11 to the designated position, it is detected by the sensor 13. The control system 5 then stops the horizontal drive 12, and the handling module 3 begins handling the product, achieving precise automated operation.

[0025] The transport module 3 includes a base 14, an articulated arm 15, a fixed base plate 16, a lifting bracket 17, a rotation drive device and a first lifting drive device 18. The base 14 is fixedly mounted on the frame 1, one end of the articulated arm 15 is hinged on the base 14 and can rotate around a vertical axis, the fixed base plate 16 is fixedly mounted on the other end of the articulated arm 15, the lifting bracket 17 can be mounted on the fixed base plate 16 in the longitudinal direction, and the clamping claw mechanism 19 is fixedly mounted on the lifting bracket 17. The rotation drive device drives the articulated arm 15 to rotate, and the first lifting drive device 18 drives the lifting bracket 17 to move up and down. The control system 5 controls the start and stop of the rotation drive device and the first lifting drive device 18.

[0026] The articulated arm 15 is preferably a two-section articulated structure, and the handling module 3 forms a four-axis manipulator to achieve precise handling of the sub-product 7. This can also be a handling system that slides along the X direction, Y direction and Z direction, which can achieve precise handling of the sub-product 7 in three-dimensional space. It is an equivalent replacement structure that can be easily thought of by technical personnel in this field based on this patent, and is within the scope of protection of this patent.

[0027] The transport module 3 also includes a first balancing bracket 20, a second balancing bracket 21, a second lifting drive device and a third lifting drive device. The first balancing bracket and the second balancing bracket 21 can be lifted and lowered respectively and are arranged below the lifting bracket 17. The second lifting drive device and the third lifting drive device are respectively fixedly installed on the base 14. The second lifting drive device and the third lifting drive device respectively drive the first balancing bracket 20 and the second balancing bracket to lift and lower. At least two first balancing push rods 22 are fixed on the first balancing bracket 20, and at least two second balancing push rods 23 are fixed on the second balancing bracket. The first balancing push rods 22 can be symmetrically pressed against the horizontal surface of the upper structure of the sub-product 7, and the second balancing push rods 23 can be symmetrically pressed against the horizontal surface of the lower structure of the sub-product 7. The first balancing push rod 22 on the first balancing bracket 20 and the second balancing push rod 23 on the second balancing bracket cooperate with the clamping claws to achieve a stable clamping and positioning of the sub-product 7, while ensuring that the lower end of the sub-product 7 remains horizontal, so that it is convenient for it to be accurately placed on the sub-heating positioning device of the heating module 4 for precise positioning. The first balancing push rod 22 and the second balancing push rod are preferably four evenly and symmetrically arranged.

[0028] The lower end of the second balancing push rod 23 forms a T-shaped structure. The lower section of the T-shaped structure, which has a smaller diameter, can be inserted into a longitudinal hole on the lower horizontal surface of the sub-product 7, while the upper section of the T-shaped structure, which has a larger diameter, abuts against the lower horizontal surface of the sub-product 7. This structure can improve the precise positioning of the sub-product 7 by the handling module 3 during handling, preventing the sub-product 7 from tilting, deflecting, etc. during handling.

[0029] The heating module 4 includes a cylindrical channel 24 fixed on the frame 1 and matching the shape of the sub-product 7. A through opening 25 is provided on the horizontal surface 8 for the sub-product 7 to pass through. The through opening 25 is aligned with the cylindrical channel 24 of the heating module 4. The heating device is a high-frequency heating coil 26 fixedly installed in the cylindrical channel 24. The sub-product heating positioning device can slide up and down in the cylindrical channel 24 so that the sub-product 7 sinks into the cylindrical channel 24 of the heating module 4 or rises to the upper side of the horizontal surface 8. The heating module 4 also includes a fourth lifting drive device 27 and a second sub-product sensing device 28.

The second sub-product sensing device 28 is electrically connected and communicates with the control system 5. The control system 5 controls the start and stop of the fourth lifting drive device 27. After the sub-product 7 is transported to the top of the through opening 25 by the transport module 3, the sub-product heating and positioning device rises, and the transport module places the sub-product 7 on the sub-product heating and positioning device for positioning. Then the sub-product heating and positioning device drives the sub-product 7 down into the cylindrical passage, and the insert of the sub-product 7 and the insert thereon are heated at high speed by the high-frequency coil. After the heating is completed, the sub-product heating and positioning device rises to facilitate the transport module to transport it away. The structure is simple, the heating efficiency is high, and there will be no collision. In addition, other heating modes can also be used to achieve rapid heating. In addition to the lifting method, the sub-product heating positioning device can also move horizontally to enable the sub-product 7 to enter the heating position.

[0030] The heating module 4 also includes a temperature measuring device. An alarm 29, a human-machine interface 30, and control buttons 31 are also fixedly mounted on the outer housing 9. The temperature measuring device is capable of detecting the surface temperature of the insert and the insert of the insert product 7. The temperature measuring device is electrically connected to and communicates with the control system 5, which controls the start and stop of the heating device and the alarm 29. The human-machine interface 30 and control buttons 31 are electrically connected to and communicate with the control system 5, allowing control data to be input into the human-machine interface 30. The temperature measuring device includes a high-precision infrared temperature sensor 32 and a standard infrared temperature sensor 33. The high-precision infrared temperature sensor is used to accurately measure the real-time heating temperature of the insert, while the standard infrared temperature sensor is used to measure the surface temperature of the insert.

[0031] There are two heating modules 4, spaced apart and arranged on the frame 1. The handling module 3 alternately places the sub-products 7 from the loading module 2 onto the sub-product heating positioning devices of the two heating modules 4. The two heating modules 4 operate simultaneously, which can greatly improve the heating efficiency of the sub-products 7, thereby improving the production efficiency of the factory.
