The magnetic yoke comprises a rectangular base plate 2, 7 pieces of magnetic iron 3 and a frame 4, wherein the magnetic iron 3 and the frame 4 are both bar-shaped square iron.
The bottom surface of the permanent magnet 1 is fixed in front of the substrate 2, the bottom surface of the frame 4 is fixed at the periphery of the front of the substrate 2 and surrounds the periphery of the permanent magnet 1, and the height of the frame 4 is equal to that of the permanent magnet 1.
The magnet 3 is arranged between the two rows of permanent magnets 1, the bottom surface of the magnet 3 is fixed in front of the base plate 2, and the height of the magnet 3 is equal to the height of the permanent magnets 1.
The unloading device comprises an unloading plate 5 of antimagnetic materials, 4 pushing air cylinders 6 and two sets of reset mechanisms, wherein the 4 pushing air cylinders 6 are divided into two groups and are respectively arranged on the upper side and the lower side of the sucker, the two sets of reset mechanisms are arranged on the left side and the right side of the sucker, and the unloading plate 5 is arranged in front of the permanent magnet 1 and the frame 4.
The cylinder body of the pushing cylinder 6 is fixed at the edge of the rear face of the base plate 2, and the front end of a piston rod of the pushing cylinder 6 penetrates through piston rod holes in the base plate 2 and the frame 4 and faces the unloading plate 5.
The reset mechanism comprises a reset cylinder 7, a cross beam 8 and two groups of guide rod and guide sleeve combinations 9, the cylinder body of the reset cylinder 7 is fixed at the edge of the rear surface of the base plate 2, and the piston rod faces backwards; the middle part of the cross beam 8 is fixed at the rear end of a piston rod of the reset cylinder 7, two sets of guide rod guide sleeve combinations 9 are arranged at two sides of the reset cylinder 7, a guide sleeve 901 of each guide rod guide sleeve combination 9 is fixed at the rear of the substrate 2, the rear end of each guide rod 902 is fixed at the end part of the cross beam 8, and the front end of each guide rod 902 passes through guide rod holes in the substrate 2 and the frame 4 to be connected with the unloading plate 5.
In the above embodiment, the substrate 2 is preferably made of a pure iron plate or stainless iron having a thickness of 10MM and a purity of 98% or more, and the frame 4 is preferably made of 4 pure square iron such as 10mm×10MM or 16mm×10 MM.
The magnetic flux of the permanent magnet 1 is found according to the difference of the attractive force (such as 4500 gauss or 3000 gauss) of the permanent magnet 1, each individual permanent magnet 1 has a certain magnetic flux, and the size and the thickness of the magnet determine the difference of the magnetic fluxes, namely the lengths of magnetic lines of force are different. The magnetic flux of each individual is found out, the distance between each individual is calculated, the magnetic force lines of one single magnet are just contacted with the magnetic force lines of the other single magnet, the magnetic force lines cannot be overlapped too much or too far apart, the magnetic force is overlapped too much, the adsorption force is strong, but the adsorbate is easy to turn over and is too far apart, the adsorption force is weakened, and the adsorbate can slide. The adsorbate is easy to turn over in the sliding process, and the magnetic force lines of the two single magnets are required to be just contacted.
Because the area of the sucker is large, the adsorption force of the middle part of the sucker is not as good as that of the periphery of the sucker, the magnetic fluxes in the middle of the sucker cannot be smoothly reacted, and the magnetic forces possibly offset each other, so that the magnet 3 is added in the middle of each row of single magnets, the size of the magnet 3 is determined according to the length of magnetic lines of force (such as 10mm×10MM or 16mm×10 MM), when the magnetic lines of force of two rows of magnets touch the magnet 3, a certain amount of magnetic lines of force can be prolonged along the surface of the magnet 3, a small part of magnetic lines of force can penetrate the magnet 3 to collide with the magnetic lines of force of the same quantity on the other side (because of the permanent magnet 1 installed in the same polarity, the length of the magnetic lines of force of the two single magnets is found before the magnet is installed above, the attraction of the magnet is the same), so that the magnetic lines of force of the two rows of magnets can penetrate the magnet 3, and the magnetic lines of force of the two rows of magnets can be prolonged in the same direction.
The length of the magnetic lines of force can be measured by means of an attracting object. The method comprises placing stainless steel, aluminum or copper rods with different lengths, which are not adsorbed by magnet, or glue rod with diameter below 5MM (too thick to weaken magnet attraction), directly above the sucker (the side with frame of pure iron plate with magnet, i.e. the side with magnet), placing adsorbate on the top of the rod, and turning over the whole magnetic disk to prevent adsorbate from falling. The length of the measuring rod is the length of the magnetic force line of the vacuum suction force of the actual magnet (the weight of the sucked object is inversely proportional to the vacuum distance of the suction, the heavier the object is, the shorter the suction distance is, and the lighter the object is, the longer the suction distance is
After the sucking disc adsorbs objects, the objects are unloaded, and one side of the sucking disc with a magnet is provided with a high-purity stainless steel plate or copper plate with the same size and thickness as the sucking disc and about 2MM as an unloading plate. Six cylinders are arranged on the back surface of the sucker, namely a pure iron plate arranged on the permanent magnet, 4 cylinders are unloading cylinders (pushing cylinders), and 2 cylinders are resetting cylinders. The thrust of the unloading cylinder is greater than the suction force between the suction cups with the adsorbate. The unloading cylinder has small thrust, the bottom unloading plate is not moved, and the adsorbate cannot fall off. The unloading cylinder is too big, can increase the cost, has also increased the height of whole sucking disc and has made the use and the installation of sucking disc difficult. A suitable cylinder can enable the sucker to absorb and unload adsorbate at a certain time as required.
According to the matrix type permanent magnet sucker disclosed by the embodiment of the utility model, the faces with the same polarity of the permanent magnet are fixedly arranged on the same plane, equal magnetic force lines of the permanent magnet of each single body are forced to extend in the same direction under the action of mutual repulsion, equal magnetic force lines of the single body are mutually collided, the equal magnetic force lines of the single body are prolonged in the same direction, and the adsorption force of the magnet is increased when the magnetic force lines are longer.
For example, the matrix permanent magnet sucker 400mmx360MM in the embodiment of the utility model can absorb weights of nearly hundred kilograms at intervals of 100MM-250MM or even more, so that the permanent magnet sucker with large area and large interval distance is obtained, the adsorbate can not turn over, and the adsorption weight is large.
