stop when sliding to the lower part of the transverse plate 7, detection work is carried out, through the meshing transmission between the worm wheel 504 and the worm 503 and between the transmission gear 506 and the transmission toothed plate 507, under the driving of the second servo motor 502, automatic conveying and detection work of the electric control board can be realized, the detection efficiency can be effectively improved, the position moving precision of the placing table 3 is also effectively improved, the position control of the placing table 3 is more accurate, the movement process is more stable, when the detection work of the electric control panel is carried out, firstly, the second adjusting screw 603 is driven to rotate by the driving motor 601, under the meshing transmission between the second adjusting screw 603 and the second screw sleeve 604, the second screw sleeve 604 drives the whole transverse plate 7 to move downwards, so that the detection contact 8 at the bottom of the transverse plate 7 is contacted with the surface of the electric control panel, the two detection contacts 8 are respectively connected with the input port and the output port of the electric control panel to form a detection loop, the detection contact 8 is electrically connected with a detection host, the detection host can adjust the detection program according to the type of the electric control panel, display and record the detection data, thereby completing the detection work, when the detection contact 8 moves to the upper part of the electric control panel, through the driving of the first control motor 901 and the second control motor 906, under the screw-thread fit between the first control screw rod 902 and the second control screw rod 907 and between the first control screw rod sleeve 903 and the second control screw rod sleeve 908, the positions of the two detection contacts 8 at different positions can be respectively adjusted, the positions of the input port and the output port on the surface of the electric control board can be different due to the different models of the electric control board, the positions of the detection contacts 8 can be respectively adjusted according to the different models of the electric control board, so that the detection equipment can be suitable for the electric control boards with different models, the detection cost can be effectively reduced, when the detection contacts 8 move downwards to contact with the spherical contacts on the surface of the electric control board, the lower surface of the annular conductive block 805 at the bottom of the detection contacts firstly contacts with the tops of the spherical conductive contacts on the surface of the electric control board, and when the detection contacts continue to move downwards, the annular metal connecting sheet 806 outside the annular conductive block 805 can deform, because the annular metal connecting sheet 806 is compressed in a wavy manner, under the connecting action of the auxiliary spring 803, the downward movement of the whole position of the extension rod 801 under the abutting action of the spherical contact on the surface of the circuit board below can make the annular conductive block 805 move upwards, and further drive the annular metal connecting sheet 806 on the outer side to move, so that the annular metal connecting sheet 806 can change according to the shape of the spherical contact on the surface of the circuit board, and then through the concave arrangement of the lower surface of the annular conductive block 805, the annular conductive block 805 and the annular metal connecting sheet 806 can have larger contact areas with the contacts on the circuit board, thereby effectively reducing the occurrence of broken contact conditions and being more beneficial to detection work, after the detection is completed, after the detection contact 8 is disengaged from the electrical control board, under the elastic action of the auxiliary spring 803 and the self-elastic force of the annular metal connecting sheet 806, the annular metal connecting piece 806 can be reset, and the change of the overall shape of the annular metal connecting piece 806 enables the detection contact 8 to be suitable for detection contacts with different sizes on different types of electric control boards.
