[0025] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the following will be described clearly and completely in combination with the technical solution in the embodiments of the utility model. Obviously, the described embodiments are partial embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the utility model.

[0026] A current limiting integrated suction cup with a magnet in a preferred embodiment of the utility model; Figure 1-2 As shown, it includes a fixing component 10 connected to peripheral components (such as an adjustment plate), and a guide component 30 connected to the fixing component. The guide component is connected and locked with the fixing component through a locking component 50. The lower end of the guide component is connected to a suction component 20. After the PCB board is adsorbed by the suction component, the suction cup moves to complete the absorption and movement of the PCB board.

[0027] Specifically, Figure 2As shown, the fixing assembly 10 includes a fixing base 100, a magnet 101 is connected to the upper end of the fixing base, and a locking screw 500 for fixing the magnet. The magnetic force of the magnet 101 and the adjusting plate are magnetically attracted to each other, and the magnetic attraction member 104 is fixed on the adjusting plate, so that the fixing base 10 can be fixed on the adjusting plate. And when the position of the fixing base 10 needs to be moved, it is only necessary to move the position of the magnet 101 on the adjusting plate. The magnet can also be replaced by a buckle or other detachable locking structure to fix the fixing base on the adjusting plate. The guide assembly 30 includes a guide rod 300, and a spring 301 sleeved on the guide rod. The upper end of the guide rod is connected to the fixing base through a locking assembly, and the lower end is connected to the suction assembly 20. A suction head 200 and a suction head fixing seat 200 connecting the suction head to the guide rod are arranged at the lower end of the suction component. A dustproof component 40 is arranged at the connection between the guide rail and the fixing seat. The dustproof component includes a bearing fixing seat connected to the fixing seat, and a dustproof bearing arranged in the bearing fixing seat. When the equipment is used in a dusty environment, the dustproof component can prevent dust from entering the guide rod 300, thereby improving the stability of the equipment.

[0028] Furthermore, if Figure 3 As shown, the fixing seat 100 is in an I-shape, and a magnet chamber 1003 is provided on the upper end 1000 of the fixing seat. The magnet 101 is placed in the magnet chamber, and a locking hole 1005 is provided in the magnet chamber corresponding to the locking screw, and the magnet is connected to the fixing seat through the locking screw. In order to make the magnet more firmly connected to the fixing seat, an overflow glue groove 1004 is provided in the magnet chamber, and the overflow glue groove is formed by extending downward from the axial side of the magnet chamber. Excessive glue is collected through the overflow glue groove to prevent the glue from overflowing onto the surface of the magnet when the screw is tightened, thereby affecting the cleanliness of the product surface. Locking grooves 1007 are provided on the left and right sides of the lower end 1002 of the fixing seat, and the guide rod 300 is placed at the locking groove and can move up and down in the locking groove.

[0029] Furthermore, if Figure 3-4 and Figure 6As shown, the upper end of the guide assembly 30 is connected to the fixed seat through the locking assembly 50, and the guide rod 300 includes a movable column 3000, a spring sleeve is arranged on the movable column, and the movable column part passes through the locking groove and is connected to the lower end of the fixed seat through the locking assembly 50. The locking assembly includes a locking screw 500 connected to the stop end 3003 of the guide rod 300, the radius of the locking screw is greater than the radius of the locking groove to prevent the guide rod from passing through the locking groove, and a gasket 501 is arranged between the locking screw and the fixed seat to increase the locking force of the locking screw, and the lower end of the gasket is connected to the fixed seat through a buffer pad, and the buffer pad can be selected to be a rubber material, so that the movable rod generates a buffer force during the descent process. At the same time, in order to facilitate the removal of the locking screw, a U-shaped groove 1006 is arranged on the upper end of the fixed seat corresponding to the locking groove, and a tool such as a screwdriver is passed through the U-shaped groove to lock and unlock the locking screw. When replacing accessories, disassembly and assembly are more convenient, and when locking the screw, the tightening force can be better controlled, so that the product will not be easily damaged. The upper end 1000 of the fixing seat and the lower end 1002 of the fixing seat are connected by the fixing seat vertical arm 1001, so there is a distance between the locking groove and the U-shaped groove. The distance is the same as the height of the vertical arm and is also the travel of the guide rod. Therefore, the radius of the U-shaped groove should be smaller than the radius of the locking screw.

[0030] Furthermore, if Figure 3-5 As shown, the guide rod 300 is provided with a dustproof assembly 40, which includes a dustproof bearing 400 sleeved outside a part of the guide rod, and a bearing fixing seat 401 sleeved outside the dustproof bearing, a through hole 4010 is provided in the bearing fixing seat, the guide rod passes through the through hole to connect with the fixing seat, and two groups of locking holes are provided on the bearing fixing seat, and two groups of locking holes are correspondingly provided at the lower end of the fixing seat, and locking screws are connected in the locking holes to connect and fix the bearing fixing seat with the lower end of the fixing seat. A bearing seat 4011 is provided in the bearing fixing seat, the dustproof bearing 400 is arranged in the bearing seat, and the guide rod passes through the dustproof bearing.

[0031] Furthermore, if Figure 4 and Figure 6 As shown, the suction assembly 20 includes a suction head fixing seat 201 connected to the guide rod, and a suction head 200 is arranged at the lower end of the suction head fixing seat, and the suction head can suck the PCB board by means of a negative pressure tube or a suction cup. The guide column can be arranged in two groups to prevent the fixing seat 10 or the suction assembly 20 from rotating around a single guide rod 301 during the movement, and also reduce the production cost.
