Description

Technical Field

[0001] The invention belongs to the technical field of motor manufacturing equipment, and in particular relates to a sheet punching and unscrambling machine. Background Art

[0002] In the production process of motor stators, it is necessary to sort out the multiple stampings obtained by stamping. For a long time, stator stampings have been sorted either manually or by vertical sheet sorting machines.

[0003] As labor costs continue to rise, manual film sorting has many disadvantages and is gradually being eliminated. Most of the existing film sorting machines have complex structures, occupy large spaces, and are not very reliable. Moreover, they require more manual participation and have a low degree of automation.

[0004] In addition, when using a vertical film sorting machine for film sorting, it is necessary to configure the rotating shaft according to the film model. Each model must have a dedicated rotating shaft. Although this is an improvement over the manual film sorting method, replacing the rotating shaft is more complicated, the labor intensity is still high, and the efficiency is low. Summary of the invention

[0005] Aiming at the shortcomings of the existing unreasonable structure of the wafer processing machine, the present invention provides a wafer punching and processing machine, optimizes the structure, improves the working reliability and improves the efficiency.

[0006] To achieve the above object, the present invention adopts the following technical solution: a film punching and unpacking machine, the film punching and unpacking machine comprising:

[0007] Mounting seat;

[0008] a mounting ring supported by a mounting seat;

[0009] Magnets, the magnets are in multiple numbers and distributed circumferentially, and the magnets are fixed on the mounting ring and stand upright;

[0010] A cushion, the cushion being arranged inside the magnetic steel;

[0011] A mandrel, wherein the mandrel is disposed on the cushion member;

[0012] A positioning member, wherein the positioning member is fixed on the cushion member;

[0013] The rotating assembly is arranged on the mounting seat, and the rotating assembly drives the mounting ring and the magnetic steel to rotate relative to the positioning member.

[0014] The sheet punching and sorting machine of the present invention has a rotating assembly, a magnetic steel driven by the rotating assembly, and a positioning piece. The stator sheet punching is placed in the sheet sorting machine, and the stator sheet punching is located above the positioning piece. At this time, the rotating assembly drives the mounting ring and the magnetic steel to rotate relative to the positioning piece. Under the action of the magnetic steel, the stator sheet punching also rotates. The positioning notch on the stator sheet punching will align with the positioning piece, and the positioning piece prevents the stator sheet punching from rotating. When the number of stator sheet punching is large enough, the suspended magnetic force from the magnetic steel on the stator sheet punching is not enough to support the stator sheet punching, and the stator sheet punching will fall due to the repulsion of the same poles. The stator sheet punching is placed in the sheet sorting machine preferably by automatic transmission with a conveyor belt. The positioning notch on the stator sheet punching can utilize an existing unique groove, or it can be opened separately.

[0015] As an improvement, the punching and unscrambling machine further includes a lifting assembly, which drives the mounting seat, mounting ring, magnetic steel relative pad and positioning member to rise and fall. When arranging the last few punching sheets, the punching sheet may not be able to descend due to insufficient repulsion between the same poles. At this time, the lifting assembly drives the mounting seat, mounting ring and magnetic steel relative positioning member to descend, and the suspension force from the magnetic steel on the punching sheet is reduced, and the punching sheet will fall and be embedded in the positioning member. By setting up the lifting assembly, the last few punching sheets can be arranged.

[0016] As an improvement, the lifting assembly includes a lifting motor and a lead screw pair, and the lead screw pair is fixedly connected to the mounting seat.

[0017] As an improvement, the sheet punching and sheet sorting machine further comprises a guide assembly, which guides the lifting and lowering of the mounting seat, the mounting ring and the magnetic steel.

[0018] As an improvement, the guide assembly includes a plurality of columns, which pass through the mounting seat and are fixedly connected to the cushion member. The guide assembly not only guides the lifting and lowering of the mounting seat, the mounting ring, and the magnetic steel, but also supports the cushion member.

[0019] As an improvement, the rotating assembly includes a rotating motor and a gear set driven by the rotating motor, the driving wheel of the gear set is fixedly connected to the output shaft of the rotating motor, and the driven gear of the gear set is fixedly connected to the mounting ring.

[0020] As an improvement, the driven gear is a gear ring; an accommodating cavity is provided on the upper surface of the mounting seat, and the mounting ring is rotatably disposed in the accommodating cavity.

[0021] As an improvement, the positioning member is fixedly connected to the cushion member via a trapezoidal groove, a dovetail groove or a circular groove.

[0022] As an improvement, the height of the positioning member is lower than the magnetic steel.

[0023] As an improvement, the inner side of the upper end of the magnetic steel has a guiding slope.

[0024] As an improvement, the upper end of the core shaft is rounded.

[0025] The beneficial effect of the sheet punching and sheet sorting machine of the present invention is that the stator sheet is placed in the sheet sorting machine, and under the action of the magnetic steel, the stator sheet is suspended in the sheet sorting machine and is located above the positioning piece. At this time, the rotating component drives the mounting ring and the magnetic steel to rotate relative to the positioning piece. Since the stator sheet is attracted by the magnetic steel, the stator sheet also rotates accordingly. When the positioning notch on the stator sheet is aligned with the positioning piece and the number of the stator sheet is sufficient, the stator sheet will fall due to the repulsion of the same poles.

[0056] Embodiment 1

[0057] See also Figures 1 to 10 , a film punching and film sorting machine of the present invention, the film punching and film sorting machine comprises:

[0058] Mounting seat 1;

[0059] A mounting ring 2, wherein the mounting ring 2 is supported by the mounting seat 1;

[0060] Magnetic steel 3, the magnetic steel 3 is in multiple number and distributed circumferentially, and the multiple magnetic steels 3 are fixed on the mounting ring 2 and stand upright;

[0061] A cushion member 4, wherein the cushion member 4 is arranged inside the magnetic steel 3;

[0062] A mandrel 5, wherein the mandrel 5 is arranged on the cushion 4;

[0063] A positioning member 6, wherein the positioning member 6 is fixed on the cushion member 4;

[0064] A rotating assembly 7, wherein the rotating assembly 7 is disposed on the mounting seat 1, and the rotating assembly 7 drives the mounting ring 2 and the magnetic steel 3 to rotate relative to the positioning member 6;

[0065] A lifting assembly 8, wherein the lifting assembly 8 drives the mounting seat 1, the mounting ring 2, and the magnetic steel 3 to rise and fall relative to the cushion 4 and the positioning member 6;

[0066] The guide assembly 9 guides the lifting and lowering of the mounting seat 1, the mounting ring 2, and the magnetic steel 3.

[0067] When arranging the last few punching sheets, the punching sheets may not be able to descend due to the insufficient repulsion force of the same poles. At this time, the lifting assembly 8 drives the mounting seat 1, the mounting ring 2 and the magnetic steel 3 to descend relative to the positioning member 6, and the suspension force of the punching sheet from the magnetic steel 3 is reduced, and the punching sheet will fall and be embedded in the positioning member 6. The lifting assembly 8 is set to arrange the last few punching sheets.

[0068] As an improvement, the lifting assembly 8 includes a base 81 , a lifting motor 82 mounted on the base 81 , and a lead screw pair 83 , and the lead screw pair 83 is fixedly connected to the mounting seat 1 .

[0069] As an improvement, the guide assembly 9 includes a plurality of columns 91, which pass through the mounting seat 1 and are fixedly connected to the cushion 4. The guide assembly 9 not only guides the lifting and lowering of the mounting seat 1, the mounting ring 2, and the magnetic steel 3, but also supports the cushion 4.

[0070] As an improvement, the rotating assembly 7 includes a rotating motor 71 and a gear set driven by the rotating motor 71 , the driving wheel 72 of the gear set is fixedly connected to the output shaft of the rotating motor 71 , and the driven wheel 73 of the gear set is fixedly connected to the mounting ring 2 .

[0071] As an improvement, the driven wheel 73 is a gear ring; an accommodating cavity 11 is provided on the upper surface of the mounting seat 1, and the mounting ring 2 is rotatably disposed in the accommodating cavity 11.

[0072] As an improvement, the positioning member 6 is fixedly connected to the cushion member 4 via a trapezoidal groove. In other embodiments, the positioning member 6 can also be fixedly connected to the cushion member 4 via grooves of other shapes such as dovetail grooves or circular grooves. The cross-sectional shapes of the positioning member 6 are consistent for easy processing.

[0073] As an improvement, the height of the positioning member 6 is lower than the magnetic steel 3 .

[0074] As an improvement, the inner side of the upper end of the magnetic steel 3 has a guiding slope.

[0075] As an improvement, the upper end of the core shaft 5 is rounded.

[0076] The stator punching sheet 0 of the punching and sorting machine applicable to this embodiment has a positioning notch 01 formed thereon, the positioning notch 01 is formed at the edge, the positioning notch 01 is rectangular, and the position of the positioning notch 01 is calculated and does not affect the performance of the stator punching sheet 0. In other embodiments, if the stator punching sheet 0 has a unique groove that can be used for positioning, there is no need to separately form a positioning groove.

[0077] The working principle of the sheet punching and sorting machine of the first embodiment of the present invention is: the stator sheet 0 is placed between the magnetic steels 3 of the sheet sorting machine. Under the action of the magnetic steels 3, the stator sheet 0 is suspended in the sheet sorting machine and is located above the positioning member 6. At this time, the rotating component 7 drives the mounting ring 2 and the magnetic steel 3 to rotate relative to the positioning member 6. Since the stator sheet 0 is attracted by the magnetic steel 3, the stator sheet 0 also rotates accordingly. When the positioning notch 01 on the stator sheet 0 is aligned with the positioning member 6, since the stator sheet 0 below is always subject to the repulsive force of the stator sheet 0 above, and the number of stator sheet 0 is sufficient, when the gravity and repulsive force of the stator sheet 0 are greater than the suspension magnetic force provided by the magnetic steel 3, the stator sheet 0 will fall under the repulsion of the same poles, and the positioning member 6 enters the stator sheet The positioning notch 01 of the stator sheet 0 is formed in the positioning notch 01 of the stator sheet 0, thereby realizing the arrangement of the stator sheets 0 one by one in turn. For the last sheet or several stator sheets 0, the suspension magnetic force provided by the magnetic steel 3 may be greater than its gravity and the downward repulsive force it receives (for the last stator sheet 0, the magnetic force of the magnetic steel 3 it receives and the upward repulsive force it receives may be greater than its gravity), resulting in the positioning notch 01 of the stator sheet 0 being unable to enter the positioning member 6 and descend. At this time, the lifting assembly 8 drives the magnetic steel 3 to descend, the suspension magnetic force received by the stator sheet 0 decreases, and the stator sheet 0 is able to fall, thereby realizing the arrangement of all stator sheets 0. When a certain number or height is reached, the sheet sorting machine stops working, and the neatly arranged stator sheets 0 can be taken out. The magnetic force required by the magnetic steel 3 can be calculated and adjusted according to the weight of the stator sheet 0.

[0078] The beneficial effects of the sheet punching and sheet sorting machine of the first embodiment of the present invention are: the stator sheet punching 0 is driven to rotate by the rotating component 7 and the magnetic steel 3, the positioning member 6 is set to position the stator sheet punching 0, and the magnetic steel 3 is raised and lowered relative to the positioning member 6 by the lifting component 8, with a high degree of automation and fast and reliable sheet sorting.

[0079] Embodiment 2

[0080] The difference between the second embodiment and the first embodiment lies in the magnitude of the magnetic force of the magnetic steel 3 and the fact that the lifting assembly 8 and the guiding assembly 9 are not provided.

[0081] See also Fig.11 In the second embodiment, the magnetic force provided by the magnetic steel 3 to the stator sheet 0 is smaller than the gravity of the stator sheet 0. After the stator sheet 0 is placed in the sheet sorting machine, the stator sheet 0 will contact the positioning member 6. Since the gravity of the stator sheet 0 is larger than the sum of the magnetic force from the magnetic steel 3 and the repulsive force from the adjacent stator sheet 0, the magnetic steel 3 does not need to be lowered.

[0082] The other structures and effects of the second embodiment are the same as those of the first embodiment, and will not be described in detail here.

[0083] The above is only a specific implementation of the invention, but the protection scope of the invention is not limited thereto. Those skilled in the art should understand that the invention includes but is not limited to the contents described in the drawings and the above specific implementation. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
