[0016] The utility model is a marking device for a three-dimensional Hall switch type sensor, and the operation process is as follows:
[0017] The three-dimensional Hall switch sensor is manually placed into the limit slot 4. The placement process is to hold the circuit board and push it directly toward the insertion port 4-4 until it cannot be pushed anymore, that is, the circuit board has abutted against the abutment surface 4-2. At this time, the circuit board is in place. In this process, the circuit board enters the insertion port 4-4 along the wedges 6 on both sides. The open design makes it easier to align. When the circuit board enters the limit slot 4, the edge of the circuit board first abuts against the wedge 6, and then abuts against the inclined surface 8-1 of the pressure block 8. The pressure block 8 is connected to the spring 7. The circuit board presses the pressure block 8, and the pressure block 8 presses the spring 7. The restoring force of the spring 7 can make the pressure block 8 abut against the circuit board more tightly, so that the circuit board will not be thrown out when the turntable 3 rotates. The convex strip 5 on the bottom surface 4-1 of the limit groove 4 can make the circuit board higher relative to the bottom surface 4-1 after being inserted into the limit groove 4, so as to avoid friction between the circuit board and the bottom surface 4-1 when the circuit board is collected. At the same time, because the circuit board is raised, and the side surface 4-3 and the wedge block 6 are radially protruding from the bottom surface 4-1 along the turntable 3, the outer side of the circuit board is actually vacant and exposed, which is convenient for placement and taking. The circuit board can be put into place in one step, which simplifies the steps of placement and taking and saves operation time. Start the stepper motor to drive the turntable 3 to rotate. The turntable 3 rotates at a certain angle so that each limit groove 4 is located below the laser marking machine 2 in turn. The interval time of the stepper motor rotation is determined according to the marking time of the laser marking machine 2. After marking, it can be rotated to mark the next circuit board. During this marking interval, the operator can take out the marked circuit board and place the unmarked circuit board, which saves waiting time and improves work efficiency. The up and down front and back positions of the laser marking machine 2 can be adjusted by the vertical adjustment unit and the horizontal adjustment unit of the adjustment component.
