Therefore, it is necessary to detect and compare the built-in temperature control system of the electromagnetic fusion machine with the actual temperature of the board during the heating process, so as to perform internal calibration compensation on the temperature controller.

[0014] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0015] In order to solve the above technical problems, this embodiment provides a temperature measurement and calibration system for an electromagnetic fusion machine, such as Figure 1-2As shown, the electromagnetic fusion machine comprises a temperature measuring plate 20 placed on the electromagnetic fusion machine, and a plurality of melting head assemblies 10 arranged on the electromagnetic fusion machine. After the temperature measuring plate 20 is placed on the electromagnetic fusion machine, the electromagnetic fusion machine heats the melting head assembly 10 to achieve hot pressing of the temperature measuring plate 20. A temperature measuring assembly 40 electrically connected to the electromagnetic fusion machine is arranged in the melting head assembly 10. The temperature measuring assembly 40 detects the heating temperature of the melting head assembly 10. The temperature measuring plate 20 comprises a substrate 21 and an optical plate 22 which are buckled with each other. A plurality of temperature sensing contacts 30 are arranged on the substrate 21. The position and number of the temperature contacts 30 match those of the melting head assembly 10. The temperature-sensing contacts 30 are electrically connected to an external thermometer via a temperature-sensing line 31. The external thermometer is used to detect the actual temperature of the temperature-sensing contacts 30 inside the temperature measuring plate 20, and then the heating temperature of the melting head assembly 10 of the electromagnetic fusion machine is compared with the actual temperature inside the temperature measuring plate 20, and the difference is recorded, so as to facilitate internal calibration compensation of the temperature control system of the electromagnetic fusion machine, thereby ensuring that the detected temperature of the machine during subsequent production is consistent with the actual temperature of the plate, thereby ensuring the quality of the hot pressing process.

[0016] Specifically, in order to achieve the heating effect, the melt head assembly 10 includes several groups of hot melt heads respectively located above and below the temperature measuring plate 20. The hot melt heads are symmetrically arranged above and below the plate. An electromagnetic coil 11 is arranged in the hot melt head. The plate is heated by the heat generated by the electromagnetic coil 11. The temperature measuring assembly 40 is placed in the hot melt head, and the heating temperature of the hot melt head is measured by the temperature measuring assembly 40.

[0017] Furthermore, in the above solution, a cover plate 12 is provided at the end of the hot melt head facing the temperature measuring plate 20, and the cover plate 12 is provided with a receiving groove for placing the temperature measuring component 40. The cover plate 12 is covered and fixed on the hot melt head, and then the actual heating temperature of the hot melt head is detected by the temperature measuring component 40 and fed back to the electromagnetic fusion machine.

[0018] In some embodiments, the temperature measuring component 40 is a temperature sensing sheet, and a temperature measuring module connected to the temperature sensing sheet is provided in the electromagnetic fusion machine. Then, the temperature sensing system of the electromagnetic fusion machine can display the heating temperature of the hot melt head according to the temperature feedback of the temperature measuring component 40, so as to facilitate subsequent temperature adjustment.

[0019] Furthermore, a plurality of temperature-sensing contacts 30 are made on the substrate 21, and the positions and numbers of the temperature-sensing contacts 30 correspond to the melting head assembly 10, so that the temperature of each melting head assembly 10 can be detected and compared. The temperature-sensing contacts 30 are welded to the temperature-sensing wires 31, and several temperature-sensing wires 31 are led out and connected to the temperature-sensing plug, and then the temperature-sensing plug is connected to an external thermometer. The external thermometer can detect the actual temperature of the temperature-sensing contacts 30 on the substrate 21, and simulate the actual panel product through the temperature measuring plate 20, and then compare the machine detection temperature with the actual temperature of the temperature measuring plate 20, so as to facilitate the internal calibration compensation of the temperature control system of the electromagnetic fusion machine, so as to ensure that the electromagnetic fusion machine can detect and reflect the actual temperature of the product heating during the subsequent hot pressing production of the actual panel product.

[0020] In the above scheme, a lead groove 221 is provided on the surface of the light plate 22 facing the substrate 21, and the temperature sensing wire 31 extends out of the outside of the temperature measuring plate 20 through the lead groove 221. After one end of the temperature sensing wire 31 is welded to the temperature sensing contact 30, the other end extends out of the outside of the temperature measuring plate 20 through the lead groove 221, and then multiple temperature sensing wires 31 are connected to the temperature sensing plug. Among them, a buckle structure is provided on the substrate 21 and the light plate 22, and the temperature sensing contact 30 is located between the substrate 21 and the light plate 22. It is also possible to simulate the lamination production of multi-layer boards by stacking multiple temperature measuring plates 20.

[0021] The temperature measurement calibration process of this embodiment is as follows: placing the assembled temperature sensing plate 10 on the electromagnetic fusion machine, and adjusting the position of the temperature sensing plate 10 so that the relative positions of the temperature sensing contacts 30 of the temperature sensing plate 10 and the melting head assembly 10 are consistent; then setting the temperature of the hot melting head of the melting head assembly 10 and the fusion time; then the fusion production is carried out, using an external thermometer and a temperature sensing line to connect the temperature sensing contacts 30 of the temperature sensing plate 10, the external thermometer detects the actual temperature of the temperature sensing plate 10, and the machine temperature control system detects the temperature of the hot melting head through the temperature measuring assembly 40, and observes whether the machine temperature control system and the external thermometer and the displayed temperature are consistent, especially after the temperature control system reaches the set value, and records the difference value, so as to facilitate the internal calibration compensation of the temperature control system; finally, according to the measurement results, all the melting heads are internally compensated, and re-measured to ensure that the machine temperature control system is consistent with the actual temperature of the temperature sensing plate 10, thereby completing the calibration.

[0022] In summary, the present application scheme designs a temperature measuring plate. After the temperature measuring plate is placed on the electromagnetic fusion machine, the electromagnetic fusion machine heats the temperature measuring plate by heating the melting head assembly. A temperature measuring assembly electrically connected to the electromagnetic fusion machine is arranged in the melting head assembly. The temperature measuring assembly detects the heating temperature of the melting head assembly. The temperature measuring plate includes a substrate and a light plate that are interlocked with each other. A plurality of temperature sensing contacts are arranged on the substrate. The position and number of the temperature sensing contacts match the position and number of the melting head assembly. The temperature sensing contacts are electrically connected to an external thermometer through a temperature sensing line. The actual temperature of the temperature sensing contacts inside the temperature measuring plate is detected by the external thermometer, and then the heating temperature of the melting head assembly of the electromagnetic fusion machine is compared with the actual temperature in the temperature measuring plate, and the difference is recorded, so as to facilitate the internal calibration compensation of the temperature control system of the electromagnetic fusion machine, thereby ensuring that the detected temperature of the platform is consistent with the actual temperature of the plate during subsequent production, thereby ensuring the quality of processing.
