In addition, it is not possible to perform multi-point testing during detection, and the test accuracy is difficult to guarantee.

[0004] To solve this problem, it is necessary to develop a copper foil thermal conductivity detection device. Summary of the invention

The copper foil is heated by a heating plate, and the threaded rod on the I-shaped slider is rotated to drive the test head to move downward to contact the surface of the copper foil. The temperature sensor is used to sense the temperature. The copper foil with a high temperature sensing value has good thermal conductivity, and vice versa, the thermal conductivity is poor. Therefore, batch copper foil thermal conductivity detection can be performed, and the clamping seat on one side can be adjusted in position, which is suitable for the detection of copper foil batches of different lengths, thereby improving universality.

[0041] (1) First, adjust the position of the movable clamping seat 5 according to the length of the copper foil to be tested: when adjusting, unscrew the fixing bolt 17, then the clamping seat 5 is unlocked and can slide in the trapezoidal slide groove through the trapezoidal slider 15, and after sliding to a suitable position, screw in the fixing bolt 17 to squeeze and fix the position;

[0042] (2) Then, the copper foil is placed on the surface of the heating plate 4 with both ends located on the opposite surfaces of the supporting platform 7, and the clamping bolts 6 are screwed in to tighten and fix the copper foil;

[0043] (3) After the copper foil is fixed, the hand wheel 12 is turned to drive the threaded rod 11 to rotate, thereby driving the test head 13 to move downward to perform thermal conductivity testing on the copper foil:

[0044] When the test head 13 contacts the surface of the copper foil, the hand wheel 12 is stopped, and then the heating plate 4 is started to heat, and the temperature sensor 14 is used to sense the temperature of the copper foil.

[0045] (4) After the copper foil test on one test table 2 is completed, the hand wheel 12 is rotated in the opposite direction to drive the test head 13 to move upward and reset, the latch 9 is pulled out to unlock the mounting frame 8, and the mounting frame 8 is supported to slide in the slide rail 3, so that the mounting frame 8 moves to the top of another test table 2, and then the hand wheel 12 is rotated again to drive the test head 13 to move downward, and the thermal conductivity measurement is performed again. At the same time, the locking rod 19 can be driven out of the locking groove by operating the fixing bolt 18 upward. At this time, the I-shaped slide block 10 is unlocked and can slide horizontally, so as to adjust the position of the test head 13, and then the thermal conductivity test at different points can be performed.
