[0024] Figure 1 This is a structural schematic diagram of the component fixing device in this application when determining the positioning point. Figure 2 This is a structural diagram of the component fixing device of this application when components are placed according to the positioning points. Figure 3 This is a cross-sectional view of the component fixing device of this application when the first pressure block is placed on the component, as shown in the figure. Figure 1 , Figure 2 and Figure 3 As shown, the component fixing device includes an electromagnetic module 11, a first pressure sensor 12, a first pressure block 13, and a control system 14. The electromagnetic module 11 is provided with a bearing surface 111 for placing the component 30 to be tested. The first pressure sensor 12 is mounted on the electromagnetic module 11 and at least partially protrudes from the bearing surface 111 and abuts against the component 30. The first pressure block 13 is disposed on the component 30. The control system 14 is electrically connected to the electromagnetic module 11 and the first pressure sensor 12 respectively. When the electromagnetic module 11 is turned off, the control system 14 obtains the first pressure value through the first pressure sensor 12; When the electromagnetic module 11 is powered on, it magnetically attracts the first pressure block 13, causing the component 30 to press against the first pressure sensor 12. The control system 14 obtains a second pressure value through the first pressure sensor 12 and determines a first pressure value for the component 30 based on the difference between the second and first pressure values. The control system 14 adjusts the current to keep the first pressure value stable. In this embodiment, the control system 14 selects a suitable second pressure value based on the type of component 30. The magnitude of the second pressure value can be controlled by adjusting the current. The control system 14 dynamically adjusts the current based on the first pressure value to achieve automatic pressure compensation and complete a stable pressing function.

[0025] The component fixing device of this application can magnetically attach and fix the component 30 under test through the electromagnetic module 11, and flexibly apply magnetic force by combining with the monitoring of the first pressure sensor 12. It can meet the sample fixing tasks of testing and welding of various types of components 30, has strong application capability, and can meet the requirements of downward pressing function. Since this application uses magnetic attachment to fix the component 30, there is no need for customized card plates or fixtures, which not only reduces the cost of use, but also does not restrict human operation, reduces the error caused by human operation, and improves the quality and efficiency of operation.

[0026] The component fixing device of this application can perform pressing function testing. The pressing function is suitable for soldering surface-mount components or testing scenarios where components need to be pressed onto the test bench.

[0027] Optionally, the electromagnetic module 11 includes at least two electromagnetic units 112 arranged sequentially from the center outwards.

The coil 1122 is disposed on the side wall of the electromagnet 1121, and the first pressure sensor 12 is installed in the electromagnet 1121 located in the center. When it is necessary to increase the magnetic force, it can be achieved by increasing the current and / or increasing the number of electromagnetic units 112 energized. For example, depending on the firmness of the component 30 and the position and size of the sample, the current of the coil 1122 can be adjusted, and different levels of electromagnetic units 112 can be switched or synchronously loaded to achieve a more ideal sample fixation environment. At the same time, the data is uploaded to the control system 14, and the pressure is automatically compensated to achieve stable control. In the case of repeated testing, the control system 14 has a data memory function to reduce the workload of repetitive testing. In this embodiment, the electromagnetic module 11 is formed by multiple layers of electromagnetic units 112 nested together, which can provide auxiliary fixation possibilities for different test conditions, and can also increase the strength range of magnetic attraction and improve the reliability of sample fixation.

[0029] Optionally, the component fixing device also includes a support plate 15, which is disposed on the support surface 111 of the electromagnetic module 11. When a pressing function test is required, the component 30 is placed on the support plate 15, and then the first pressing block 13 is placed on the component 30. Subsequent data acquisition and system control are the same as described above, and will not be repeated here. It is worth mentioning that when the component fixing device does not include the support plate 15, the component 30 can be directly placed on the support surface 111 of the electromagnetic module 11; when the component fixing device includes the support plate 15, the component 30 can be directly placed on the support plate 15 or the support surface 111, which can be freely selected according to actual needs.

The elastic element 19 is connected between the first unit and the second pressure sensor 18. The second pressure block 21 is disposed on the bearing surface 111 of the first unit. The component 30 is disposed on the second pressure block 21. When the electromagnetic module 11 is closed and the locking device 17 unlocks the first unit, the components 30, the second pressure block 21 and the first unit descend and compress the elastic element 19, and the control system 14 obtains the third pressure value through the second pressure sensor 18. When the electromagnetic module 11 is powered on, it lifts the second pressure block 21 and component 30 through magnetic repulsion, causing the second pressure block 21 to press component 30 onto the cover plate 16. The control system 14 acquires a fourth pressure value through the second pressure sensor 18 and determines a second pressure value for component 30 based on the difference between the fourth and third pressure values. The control system 14 adjusts the current to keep the second pressure value stable. In this embodiment, the control system 14 selects a suitable fourth pressure value based on the type of component 30. The magnitude of the fourth pressure value can be controlled by adjusting the current. The control system 14 dynamically adjusts the current based on the second pressure value to achieve automatic pressure compensation and complete the stable lifting function.
