[0002] A placement machine is a device that accurately places surface mount components on PCB pads by moving the placement head. The suction nozzle, as a form of mobile placement head, can effectively absorb surface mount components. The principle is that after the placement machine nozzle contacts the electronic components, the air inside the nozzle is sucked out, and the external pressure is greater than the internal pressure of the nozzle, forming a negative pressure, and the electronic components are pressed against the surface of the nozzle under the action of atmospheric pressure. At present, the general placement machine nozzle will generate magnetism during production operation, which will affect the quality of the product and production efficiency. Therefore, the nozzle needs to be cleaned regularly and demagnetization equipment is used to eliminate the magnetism of the nozzle. The nozzle demagnetization equipment usually uses a demagnetizer to eliminate the magnetism on the nozzle surface.

[0003] Most existing demagnetizers are fixed inside the demagnetization equipment by bolts. Although this method ensures a firm installation, when the demagnetizer is damaged or needs to be repaired, it needs to be disassembled with specific tools, which is a cumbersome operation. In addition, the maintenance personnel need to bend over and reach into the demagnetization equipment to observe and repair it, which results in a large amount of labor and low maintenance efficiency.

[0026] One end of the positioning rod 76 passes through and extends into the interior of the limiting slot 3, and one end of the positioning rod 76 is movably inserted into the inner wall of the positioning hole 5. The back of the fixed block 7 is fixedly connected to an adjusting block 77, and the outer surface of the adjusting block 77 is movably sleeved with an adjusting sleeve 78. The adjusting block 77 plays a role of telescopic movement within the adjusting sleeve 78, thereby realizing mobile adjustment. A threaded hole 79 is provided on the upper surface of the adjusting sleeve 78, and the inner wall of the threaded hole 79 is threadedly connected with a hand-tightening bolt 710. One end of the hand-tightening bolt 710 contacts the upper surface of the adjusting block 77, and the hand-tightening bolt 710 cooperates with the threaded hole 79 to limit and fix the adjusting block 77 after the adjustment is completed. The lower surface of the adjusting sleeve 78 is fixedly connected to a supporting block 711, and the lower surface of the supporting block 711 is fixedly connected to the inner bottom wall of the demagnetization device body 1.

[0027] By providing a convenient disassembly and assembly device, the demagnetizer body 6 can be quickly disassembled and assembled, the operation is convenient, the maintenance efficiency is improved, and the installation position of the demagnetizer body 6 can be moved and adjusted, thereby improving the practicality.

[0028] Working principle: Step 1, during installation, the driving plate 73 is driven to move by the pull ring 74, and the driving plate 73 is stably moved by the cooperation of the guide rod 71, and the reset spring 75 is stretched. At the same time, the movement of the driving plate 73 drives the positioning rod 76 to move, so that the positioning rod 76 is disengaged from the inside of the limit slot 3. At this time, the demagnetizer body 6 is inserted into the limit slot 3 through the limit plug 4 for preliminary positioning, and then the pull ring 74 is released. At this time, the reset elastic force of the reset spring 75 drives the driving plate 73 to reset and move, so that it drives the positioning rod 76 to insert into the positioning hole 5 to limit the limit plug 4, thereby completing the installation and positioning of the demagnetizer body 6;

[0029] Step 2: When adjusting the position of the demagnetizer body 6, first rotate the hand-tightening bolt 710 counterclockwise so that one end of the hand-tightening bolt 710 is engaged with the threaded hole 79 and is disengaged from the pressure on the adjustment block 77. Then, the position of the demagnetizer body 6 is adjusted by moving the adjustment block 77. After the adjustment is completed, rotate the hand-tightening bolt 710 clockwise to press the adjustment block 77 to fix it.

[0030] Step three, during disassembly, the pull ring 74 is used to drive the driving plate 73 to move. After the movement of the driving plate 73 drives the positioning rod 76 to disengage from the positioning groove, the demagnetizer body 6 is lifted up to drive the limiting plug 4 to move up and out of the limiting slot 3 to complete the disassembly, making it easy to remove for inspection and maintenance.
