Detailed Description

The following describes in further detail embodiments of the present invention.

As shown in fig. 1 and 2, the automatic magnetic detection device of the present invention includes a detection table 10, a slide 12 with a longitudinal length is disposed on the detection table 10, an a-piece fixing table 14 for fixing and placing an a-piece is disposed on one side (i.e., the left side in the figure) of the slide 12, and a B-piece is movably placed on the other side (i.e., the right side in the figure).

A pushing block 16 is arranged on the right side, the pushing block 16 is embedded in the slideway 12 in a clamping way and can slide along the slideway 12, a threaded through hole (not shown) is arranged in the middle of the pushing block 16, a lead screw 18 is connected in the pushing block 16 in a threaded way, and a stepping motor 20 drives the lead screw 18 to rotate so that the pushing block 16 moves along the slideway 12. In this way, the stepping motor 20 can drive the pushing block 16 to push the B workpiece to move towards the a workpiece until the magnetic attraction force between the a workpiece and the B workpiece is large enough to automatically attract the a workpiece and the B workpiece. The device also comprises a counter (not shown) for recording the number of turns of the stepping motor 20, and the counter is used for recording the number of turns of the stepping motor 20 when the magnetic force adsorption force between the workpiece A and the workpiece B enables the workpiece B to be separated from the push block 16, and the number of turns of the stepping motor 20 can be converted into the moving distance of the push block 16. In order to detect the moment when the B workpiece is separated from the push block 16, a tact switch may be provided on the push block 16, and the tact switch is always in contact during the pushing process, and is separated when the B workpiece is separated from the push block 16. The structure can be designed by ordinary technicians in the field very conveniently according to the requirements. The invention adopts the following structure:

the middle of the slide way 12 is provided with two upright posts 22, the two upright posts 22 are respectively arranged at two sides of the slide way 12, two ends of an elastic baffle plate 24 are respectively fixed on the upright posts 22 to be transversely arranged in the slide way 12, and the elastic baffle plate 24 is provided with a touch switch (not shown) which is connected with the counter.
