[0031] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0032] Reference Figure 1 and Figure 2 The present invention provides an embodiment of a magnetizer, more precisely, provides a specific embodiment of a magnetizing device of a magnetizer.

[0033] Structurally, the magnetizer mainly consists of a feeding device, a stacking device and a magnetizing device.

[0034] Among them, the feeding device mainly uses a vibrator to arrange the magnetic sheets in an orderly manner, such as laying the magnetic sheets flat along their length direction with their ends connected.

[0035] The stacking device is mainly used to stand the magnetic sheets upright and stack the magnetic sheets horizontally.

[0036] Briefly, the stacking device has an upright turntable and adsorption parts arranged along the circumference of the turntable. The adsorption parts adsorb magnetic sheets, and the turntable drives the adsorption parts to rotate, thereby making the magnetic sheets stand upright. Then, the magnetic sheets are pushed or pulled in the horizontal direction, thereby making the magnetic sheets stand upright and translate.

[0037] Since the magnetic sheets can be continuously provided, the magnetic sheets are maintained in an upright state and at the same time, the magnetic sheets are stacked in a horizontal direction.

[0038] In the case where plastic sheets are required to separate adjacent magnetic sheets, an additional feeding device needs to be provided, and the additional feeding device is used to transport the plastic sheets.

[0039] At the same time, a reciprocating translation block can also be provided, which alternately receives the magnetic sheet and the plastic sheet, thereby placing the magnetic sheet and the plastic sheet on adjacent adsorption parts, thereby achieving staggered stacking of the magnetic sheet and the plastic sheet.

[0040] For magnetizing devices, refer to Figures 1 to 3 Structurally, the magnetizing device mainly includes a conveying frame 340 , a magnetizing seat 110 and a power part 120 .

[0041] The conveying rack 340 is provided with a first material channel 100 for accommodating the magnetic sheets to pass through, so the stacking device stacks the magnetic sheets on the first material channel 100 .

[0042] Preferably, a push plate is provided at the feed end of the first material channel 100, and the push plate is driven by a cylinder. Then, the push plate continuously pushes the magnetic sheet toward the discharge end of the first material channel 100, and at the same time, space is reserved for placing new magnetic sheets.

[0043] Of course, this is just an optimized automatic method. Alternatively, the magnetic pieces can be put into the first material channel 100 manually, and human or external force can push the magnetic pieces to the discharge end of the first material channel 100.

[0044] In some preferred embodiments, the feeding rack further includes a first stud 270 , and the first stud 270 is used to support the first material channel 100 .

[0045] Therefore, the horizontal level of the first material channel 100 can be adjusted so that the first material channel 100 has a certain slope to prevent the magnetic pieces from tipping toward the feeding end of the larger material channel 550 .

[0046] Alternatively, the height of the first material channel 100 is adjusted so that the previous and next processes proceed smoothly.

[0047] The magnetizing seat 110 has a magnetizing coil therein, and the magnetizing seat 110 is provided with a first tunnel 350 through which the first material channel 100 passes. Therefore, when the magnetic sheet passes through the first tunnel 350 , the magnetizing coil magnetizes the magnetic sheet.

[0048] The power member 120 is used to drive the magnetizing seat 110 to rise and fall. Preferably, the power member 120 is a cylinder or a hydraulic cylinder.

[0049] In some preferred embodiments, a first pad 360 may be provided on the top wall of the first tunnel 350 , and the first pad 360 is used to abut against and fix the magnetic sheet.

[0050] That is to say, when the magnetizing seat 110 descends, the first pad 360 and the first material channel 100 jointly fix the magnetic piece. Meanwhile, the first pad 360 is mostly made of elastic materials such as plastic and rubber, so as not to crush or smash the magnetic piece.

[0051] For the convenience of arrangement, the present embodiment further comprises a frame having a bottom plate 370 , a top plate 380 , and a plurality of guide pillars 390 located between the bottom plate 370 and the top plate 380 . The top plate 380 is provided with a power part 120 , and the magnetizing seat 110 is slidably connected to the guide pillars 390 .

[0052] That is to say, when the power member 120 drives the magnetizing seat 110 to rise and fall, the magnetizing seat 110 moves linearly along the guide pillar 390 to avoid deflection.

[0053] For easy installation, the magnetizing seat 110 may include a seat body and a mounting plate. The seat body is provided with a magnetizing coil and a first tunnel 350 . The seat body is provided on the top of the mounting plate. Both ends of the mounting plate are slidably connected to the guide pillars 390 .

[0054] In some preferred embodiments, a lower adjusting rod 400 may be provided on the mounting plate, and the lower adjusting rod 400 is threadedly connected to the mounting plate. When the magnetizing seat 110 descends, the bottom end of the lower adjusting rod 400 abuts against the bottom plate 370, thereby stopping the magnetizing seat 110 and preventing the magnetizing seat 110 from moving further downward.

[0055] It is feasible that the lower adjustment rod 400 can also be arranged on the bottom plate 370, and the top end of the lower adjustment rod 400 abuts against the mounting plate to prevent the magnetizing seat 110 from descending, which also has the same effect.

[0056] In some preferred embodiments, the top plate 380 may be installed with an upper adjustment rod 410 , and the upper adjustment rod 410 abuts against the magnetizing seat 110 to define the highest point of the magnetizing seat 110 .

[0057] In some preferred embodiments, a limit plate 420 may be mounted on the bottom end of the upper adjustment rod 410 , and then the limit plate 420 abuts against the mounting plate to prevent the magnetizing seat 110 from further rising.

[0058] Preferably, the limiting plate 420 is slidably connected to the guide column 390 , and at the same time, the mounting plate is provided with a guide sleeve 430 for accommodating the guide column 390 , and the guide sleeve 430 abuts against the limiting plate 420 for limiting.

[0059] Therefore, when the magnetizing seat 110 rises to the highest point, the contact area is large and the impact force is small.

[0060] Reference Figure 2 In this embodiment, a front limiting mechanism 290 and a rear limiting mechanism 300 are also provided.

[0061] For details about the front limit mechanism 290, refer to Figures 3 to 5 .

[0062] Structurally, the front limiting mechanism 290 has two first cantilevers 140, two support rods 150 and a limiting seat.

[0063] The ends of the two first cantilevers 140 are fixed on the magnetizing seat 110 , the two ends of the two support rods 150 are installed on the two first cantilevers 140 , and the limiting seats are installed on the two support rods 150 .

[0064] Since the front limit mechanism 290 is installed on the magnetizing seat 110, the limit seat can move with the magnetizing seat 110, and there is no need to separately set up a structure for the lifting limit seat.

[0065] Functionally, the limiting seat has a horizontally arranged pressure cover 130, which covers the first material channel 100, thereby limiting the magnetic piece that has not been magnetized to prevent the magnetic piece from jumping up.

[0066] The pressure cover 130 is a long plate, and the length direction is arranged along the extension direction of the first material channel 100. Therefore, the length range of the limit can be expanded, the number of parts can be reduced, and the cost can be reduced.

[0067] Structurally, the limiting seat further has a connecting plate 180 , which is vertically arranged on the pressure cover 130 , and the connecting plate 180 is provided with a first through hole 190 for accommodating the support rod 150 to pass through.

[0068] Therefore, the limiting seat can be fixed, and the position of the connecting plate 180 can be adjusted along the length direction of the support rod 150, thereby adjusting the position of the limiting seat.

[0069] In some preferred embodiments, the support rod 150 is sleeved with a limiting ring 200 , and the limiting ring 200 abuts against the connecting plate 180 for limiting position.

[0070] Preferably, one support rod 150 is provided with two limiting rings 200 , so that the limiting seat can be accurately fixed to prevent the limiting seat from moving in a direction without the limiting ring 200 .

[0071] In some preferred embodiments, the front limiting mechanism 290 may further include a connecting rod 170 , and the connecting rod 170 connects the ends of the two support rods 150 on the same side.

[0072] Therefore, the stability of the two support rods 150 can be improved. At the same time, the connecting rod 170 will be located on the side away from the two first cantilevers 140. The abutment between the connecting rod 170 and the first cantilever 140 can prevent the support rod 150 from moving relative to the first cantilever 140, thereby improving stability.

[0073] Regarding the connection between the first cantilever 140 and the support rod 150 , preferably, an oblique notch 160 for accommodating the support rod 150 is provided at the top of the first cantilever 140 .

[0074] Therefore, the support rod 150 can be directly placed on the oblique notch 160 , and the support rod 150 can slide obliquely downward into the oblique notch 160 without complicated adjustment.

[0075] At the same time, when the magnetizer is working, the inner surface of the oblique notch 160 will limit the top surface of the support rod 150. Therefore, the magnetic piece not only needs to overcome the weight of the support rod 150 and the limiting seat when jumping up, but also needs to overcome the pressure and friction of the oblique notch 160 on the support rod 150. Therefore, it is less likely for the magnetic piece to jump up.

[0076] In some preferred embodiments, the support rod 150 may be provided with an upright adjusting screw 210 , and the connecting plate 180 may be provided with an adjusting nut 220 screwed together with the adjusting screw 210 .

[0077] That is, when the screwing positions of the adjusting nut 220 and the adjusting screw 210 are different, the relative positions of the connecting plate 180 and the support rod 150 in the height direction change, and then the height position of the pressure cover 130 is adjusted, which is convenient for limiting the magnetic sheets of different specifications. At the same time, it can also adapt to the situation where the first material channel 100 is tilted.

[0078] In some preferred embodiments, the connecting plate 180 may be provided with a second through hole 230680 for accommodating the adjusting nut 220 , and the adjusting screw 210 may be screwed together with the adjusting nut 220 after passing through the first through hole 190 and the second through hole 230680 .

[0079] Therefore, by rotating the nut 220 forward and reversely, the pressure cover 130 can be raised or lowered to meet the adjustment needs. Moreover, the adjusting screw 210 is set in the first through hole 190, and the adjusting nut 220 is set in the second through hole 230680. The structure is compact, which reduces the occupied space and does not affect the arrangement of the limit ring 200.

[0080] Reference Figure 3 The magnetizing seat 110 can limit the magnetic piece being magnetized. At the same time, a magnetizing coil can be arranged on or near the magnetizing seat 110 to realize the magnetizing function.

[0081] The power member 120 is used to drive the magnetizing seat 110 to rise and fall, and then the magnetizing seat 110 limits or releases the limit on the magnetic sheet.

[0082] When necessary, the magnetizing seat 110 can press and fix the magnetic piece, thereby limiting the position of the magnetic piece more effectively.

[0083] The power member 120 is preferably a combination of a cylinder and a guide rod, so that the magnetizing seat 110 can be raised and lowered quickly, and power is easily obtained.

[0084] At the same time, a manual screw can also be provided to adjust the lowest point of the magnetizing seat 110 to adapt to magnetic sheets of different specifications.

[0085] For the rear limit mechanism 300, refer to Figure 3 and Figure 4 , having a damping wheel 280 and a damping shaft 240 on which the damping wheel 280 is installed, the damping shaft 240 is provided with a damping ring 250 and a damping spring 260 , and the damping spring 260 is used to keep the damping ring 250 in contact with the damping wheel 280 .

[0086] The damping wheel 280 is preferably a rubber wheel, so it will not damage the magnetic sheet. When in use, the bottom surface of the damping wheel 280 is squeezed against the top surface of the magnetic sheet to limit the magnetic sheet and prevent it from jumping up. At the same time, it provides a certain degree of hindrance to the movement of the magnetic sheet to prevent it from scattering, which is convenient for subsequent packaging.

[0087] The damping spring 260 pushes the damping ring 250 toward the damping wheel 280 , so that the damping ring 250 and the damping wheel 280 generate relative friction, hindering the rotation of the damping wheel 280 , thereby making the damping wheel 280 have a damping effect.

[0088] By adjusting the pressure of the damping spring 260, the pressure between the damping ring 250 and the damping wheel 280 can be changed, and then the friction force can be changed, and the damping size of the damping wheel 280 can be changed to meet the use requirements.

[0089] Preferably, the first stud 270 is disposed below the damping wheel 280 .

[0090] Therefore, by adjusting the first screw 270, the distance between the first material channel 100 and the damping wheel 280 can be adjusted, which not only meets the discharge requirements but also ensures that the limit is reliable and effective.

[0091] Therefore, this embodiment has the following effects:

[0092] 1. By providing the conveyor frame 340, the conveyor frame 340 has the first material channel 100, so that it is convenient to synchronously load, magnetize and unload the magnetic sheets, realize the automation of magnetization, and improve the magnetization efficiency.

[0093] 2. The magnetizing seat 110 is provided with a first tunnel 350 for accommodating the first material channel 100 to pass through. Meanwhile, a magnetizing coil is provided in the magnetizing seat 110. Therefore, magnetization can be performed in a close manner or in a surrounding manner. The magnetization methods are diverse, and the magnetization is sufficient to ensure the magnetization quality.

[0094] 3. By setting the power piece 120, the power piece 120 drives the magnetizing seat 110 to rise and fall, and thus the magnetizing seat 110 replaces the pressure plate. On the one hand, the magnetizing coil of the magnetizing seat 110 is made as close to the magnetic sheet as possible to improve the magnetizing efficiency. On the other hand, since the weight of the magnetizing seat 110 is greater than the mass of the pressure plate, the lifting resistance is increased, resulting in the magnetizing seat 110 to lift slowly. Therefore, the restriction on the magnetic sheet is slowly released, the magnetic sheet is slowly attracted, the attraction impact between the magnetic sheets is reduced, and the defects caused by the attraction impact are reduced.

[0095] 4. By setting the front limit mechanism 290, the magnetizing seat 110 and the pressure cover 130 are used to limit the magnetic piece, and the limiting route is extended, so that the magnetic piece can be moved and magnetized smoothly, avoiding the magnetic piece from jumping from the first material channel 100, and ensuring the continuity and efficiency of the magnetization process.

[0096] 5. The pressure cover 130 can be raised and lowered together with the magnetizing base 110, which is beneficial for position limiting and convenient for maintenance.

[0097] 6. The gland 130 is installed on the magnetizing base 110, the installation reference is accurate, and the debugging workload is reduced.

[0098] 7. The rear limiting mechanism 300 is provided with a damping wheel 280, so that the magnetic sheet can be limited without affecting the removal of the magnetic sheet, thereby preventing the magnetization process from pausing.

[0099] Reference Figure 1 and Figure 2 This embodiment also has a sorting mechanism 310, which is arranged on the discharge side of the first material channel 100. The sorting mechanism 310 has a transverse pushing component 320 and a longitudinal pushing component 330 for pushing the magnetic sheets to move. The pushing direction of the transverse pushing component 320 is perpendicular to the first material channel 100, and the longitudinal pushing component 330 receives the magnetic sheets from the transverse pushing component 320, and the pushing direction of the longitudinal pushing component 330 is parallel to the first material channel 100.

[0100] The transverse push assembly 320 and the longitudinal push assembly 330 are both composed of a cylinder and a push plate, and are easy to manufacture and have low cost.

[0101] At the same time, the horizontal pushing assembly 320 and the vertical pushing assembly 330 cooperate to push the magnetic sheets and plastic sheets into rows in a quantitative manner, which is convenient for subsequent placement and sorting.

[0102] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
