Description

Technical Field

[0001] The present invention relates to the technical field of motor rotor processing equipment, and in particular to a silicon steel sheet magnet layering device. Background Art

[0002] As is well known, the motor rotor is the rotating part inside the motor and is an important component of the motor. The conventional structure of the motor rotor is mainly composed of multiple layers of silicon steel sheets (containing magnets inside) laminated by a plastic adhesive. And in order to realize the continuous rotation of the rotor around the stator, the magnets in each layer of silicon steel sheets need to be staggered by a certain angle.

[0003] Currently, when producing and assembling a motor rotor, generally, an operator first inserts magnets into the set positions of each layer of silicon steel sheets according to the product structure to stagger the magnets in each layer of silicon steel sheets by a certain angle; then stacks and injects multiple layers of silicon steel sheets. However, this processing method is time-consuming and laborious, the production efficiency is too low, and the assembly accuracy is not high, so it cannot well meet the production requirements.

[0004] In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] In order to overcome the above defects, the present invention provides a silicon steel sheet magnet layering device, which has a novel and reasonable structure, can replace manual labor to automatically stack multiple layers of silicon steel annular sheets into layers and automatically stagger and layer the magnets. It not only has high production efficiency, reliable production quality, and high production safety, but also greatly reduces the labor cost and the labor intensity.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a silicon steel sheet magnet layering device, including a first material receiving and docking mechanism, a second material receiving and docking mechanism, and a layering mechanism. The first material receiving and docking mechanism is used to receive the workpieces conveyed by the previous process, and the workpieces are silicon steel annular sheets with magnets; the second material receiving and docking mechanism is used to cooperate with the first material receiving and docking mechanism to jointly transfer the workpieces on the first material receiving and docking mechanism to the execution component of the layering mechanism; the execution component can stack multiple workpieces, and at the same time, the execution component can also act on the workpieces to stagger the magnets on the multiple workpieces placed thereon, obtaining semi-finished products that have completed the layering operation; in addition, the execution component can also cooperate with the second material receiving and docking mechanism to transfer the obtained semi-finished products to an injection molding machine in the subsequent process.

[0007] As a further improvement of the present invention, the actuating member has a carrier and a tensioning assembly A. The carrier is a vertically placed annular body for the workpiece to be sleeved thereon. The tensioning assembly A is composed of a plurality of tensioning blocks A. The plurality of tensioning blocks A are arranged in a ring on the carrier, and the plurality of tensioning blocks A can also reciprocate radially along the carrier, so that the plurality of tensioning blocks A move away from each other to tension and fix the workpiece sleeved on the carrier, or the plurality of tensioning blocks A move closer to each other to release the fixation of the workpiece sleeved on the carrier. In addition, when the plurality of tensioning blocks A are in a state of moving away from each other, the carrier can also rotate around its own axis to drive the workpiece fixed thereon to rotate by a set angle.

[0008] As a further improvement of the present invention, the layering mechanism further has a mounting plate base, a driving mechanism A and a driving mechanism B. The mounting plate base is used to receive the actuating member, the driving mechanism A and the driving mechanism B. The driving mechanism A can drive the carrier to rotate around its own axis, and the driving mechanism B can drive the plurality of tensioning blocks A to reciprocate radially along the carrier.

[0009] As a further improvement of the present invention, the driving mechanism A has a transmission shaft rotatably mounted on the mounting plate base and a power assembly A capable of driving the transmission shaft to rotate around its own axis. The carrier is coaxially arranged with the transmission shaft and fixedly connected to one end of the transmission shaft.

[0010] A plurality of receiving cavities respectively extending radially are provided in the annular wall of the carrier, and the plurality of receiving cavities are also arranged at equal intervals in the circumferential direction of the carrier. In addition, the plurality of receiving cavities respectively open on the inner and outer side walls of the carrier to form a plurality of inner sockets and a plurality of outer mounting ports. The plurality of tensioning blocks A are respectively movably arranged in the plurality of outer mounting ports.

[0011] The driving mechanism B has a driven shaft, a plurality of driven blocks A, a plurality of driven blocks B, and a power assembly B. The driven shaft is axially slidably inserted into the transmission shaft along the axial direction of the transmission shaft. One axial end of the driven shaft extends out of one axial end of the transmission shaft and is simultaneously inserted into the inner hole of the carrier. One ends of the plurality of driven blocks A are all placed in the inner hole, and inclined chutes extending axially relative to the carrier are respectively provided on one ends of the plurality of driven blocks A. The other ends of the plurality of driven blocks A are respectively slidably inserted into the plurality of receiving cavities corresponding to the plurality of inner sockets. At the same time, the other ends of the plurality of driven blocks A are respectively fixedly connected to the plurality of tensioning blocks A. In addition, elastic members for providing elastic restoring forces to the driven blocks A are respectively connected between the plurality of driven blocks A and one axial end of the driven shaft, or elastic members for providing elastic restoring forces to the driven blocks A are respectively connected between the plurality of driven blocks A and the plurality of receiving cavities. One ends of the plurality of driven blocks B are respectively fixedly connected to one axial end of the driven shaft, and inclined sliding strips extending axially relative to the carrier are respectively provided on the other ends of the plurality of driven blocks B, and the plurality of inclined sliding strips are respectively slidably disposed in the plurality of inclined chutes. In this way, when the driven shaft moves forward axially along the transmission shaft under the drive of the power assembly B, the driven shaft can drive the plurality of driven blocks B to move synchronously therewith, and further drive the plurality of driven blocks A to move radially outward along the carrier respectively, so as to realize the mutual separation of the plurality of tensioning blocks A. When the driven shaft moves backward axially along the transmission shaft under the drive of the power assembly B, the driven shaft can drive the plurality of driven blocks B to move synchronously therewith. At that time, the plurality of driven blocks A can move radially inward along the carrier respectively under the action of the elastic restoring forces of the elastic members, so as to realize the mutual approach of the plurality of tensioning blocks A.

[0012] As a further improvement of the present invention, the axial direction of the carrier is defined as the front-back direction. One axial end of the transmission shaft extends in front of the mounting plate seat, that is, the carrier is arranged in front of the mounting plate seat, and the other axial end of the transmission shaft extends behind the mounting plate seat.

[0013] The power component B has an auxiliary fixed plate A, an auxiliary movable plate A, a plurality of guide columns A extending in the front-rear direction, and a cylinder A.

[0014] As a further improvement of the present invention, the first material receiving and docking mechanism has a material receiving carrier and a pushing plate. The material receiving carrier is a vertically placed annular body for the workpiece conveyed by the previous process to be sleeved; at the same time, the material receiving carrier is also arranged opposite to the bearing member and coaxially; the pushing plate is movably sleeved outside the material receiving carrier and can horizontally reciprocate along the axial direction of the material receiving carrier;

[0015] The second material receiving and docking mechanism has an annular material receiving plate. The material receiving plate is sleeved outside the bearing member and can reciprocate axially along the bearing member; that is, the material receiving plate can move relative to the pushing plate to cooperate to transfer the workpiece sleeved on the material receiving carrier to the bearing member.

[0016] As a further improvement of the present invention, the first material receiving and docking mechanism also has a tensioning assembly B, a driving mechanism C, and a driving mechanism D. Among them, the tensioning assembly B is composed of at least two tensioning blocks B. At least two of the tensioning blocks B are arranged at intervals along the circumference of the material receiving carrier on the material receiving carrier, and at least two of the tensioning blocks B can also reciprocate radially along the material receiving carrier driven by the driving mechanism C, so that at least two of the tensioning blocks B move away from each other to realize tensioning and fixing of the workpiece sleeved on the material receiving carrier, or at least two of the tensioning blocks B move closer to each other to release the fixing of the workpiece sleeved on the material receiving carrier; the driving mechanism D can drive the pushing plate to horizontally reciprocate along the axial direction of the material receiving carrier.

[0017] As a further improvement of the present invention, the first material receiving and docking mechanism also has a driving mechanism E. The driving mechanism E can drive the material receiving carrier and the pushing plate to move closer to or away from the bearing member together.

[0018] As a further improvement of the present invention, the axial direction of the carrier is defined as the front-back direction, the carrier is arranged in front of the mounting plate seat, and the material receiving carrier is arranged in front of the carrier;

The auxiliary fixing plate B is fixedly connected to the rear side of the mounting plate seat through a plurality of the connecting rods A. The auxiliary movable plate B is movably sleeved on the connecting rods A. At the same time, the auxiliary movable plate B is also fixedly connected to the material receiving plate through a plurality of the connecting rods B. The power assembly C is installed on the auxiliary fixing plate B and can drive the auxiliary movable plate B to move and position in the front-back direction.

[0020] As a further improvement of the present invention, the silicon steel sheet magnet laminating device further includes a correction assembly for correcting the magnets on the workpiece. The correction assembly has a plurality of PIN needles, and the plurality of PIN needles are arranged in a ring and elastically installed on the front side of the mounting plate seat; in addition, a plurality of avoidance holes are also arranged in a ring on the material receiving plate, and the plurality of avoidance holes correspond to the plurality of PIN needles one by one for the plurality of PIN needles to pass through movably.

[0021] The beneficial effects of the present invention are as follows: 1) The structure of the silicon steel sheet magnet laminating device of the present invention is novel and reasonable, and can replace manual work to realize the automatic lamination of multiple layers of silicon steel annular sheets and the automatic staggered stratification of magnets. It not only has high production efficiency, reliable production quality, and high production safety, but also greatly reduces the labor cost and the labor intensity. 2) When the silicon steel sheet magnet laminating device of the present invention is working, it is required that the previous process completes the operation of inserting the magnets into the silicon steel annular sheets. However, since the factor of magnet staggering does not need to be considered when inserting the magnets in the previous process, the operation of the previous process becomes very simple and easy to implement. For example, a manipulator and a gripper can be used in combination to insert the magnets into a plurality of stacked silicon steel annular sheets at the same time, which is not only simple and easy to operate, but also has high production efficiency and high production accuracy. In short, the configuration of the silicon steel sheet magnet laminating device of the present invention is beneficial to simplifying the operation methods of other processes associated therewith, thereby improving the production efficiency and production accuracy of the entire production line. 3) The silicon steel sheet magnet laminating device of the present invention is not only applicable to the processing of motor rotors, but also applicable to the production of transformer cores, etc., and has good versatility.

[0039] The following will make a detailed description of the preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0040] Embodiment:

[0041] Please refer to the attached Figure 1 As shown, it is a three-dimensional structural schematic diagram of the silicon steel sheet magnet laminating device of the present invention.

[0042] The present invention provides a silicon steel sheet magnet laminating device, including a first material receiving and docking mechanism 1, a second material receiving and docking mechanism 2, and a laminating mechanism 3. The first material receiving and docking mechanism 1 is used to receive the workpieces conveyed by the previous process, and the workpieces are silicon steel ring sheets with magnets; the second material receiving and docking mechanism 2 is used to work in cooperation with the first material receiving and docking mechanism 1 to jointly transfer the workpieces on the first material receiving and docking mechanism 1 to the execution component 30 of the laminating mechanism 3; the execution component 30 can stack multiple workpieces, and at the same time, the execution component 30 can also act on the workpieces so that the magnets on the multiple workpieces placed thereon are staggered from each other, obtaining semi-finished products that have completed the laminating operation; in addition, the execution component 30 can also work in cooperation with the second material receiving and docking mechanism 2 to transfer the obtained semi-finished products to the subsequent process injection molding machine.

[0043] The following will make a detailed description of the specific structures of the above-mentioned various mechanisms in the silicon steel sheet magnet laminating device of the present invention.

[0044] First, the specific structure of the laminating mechanism 3 will be described.

[0045] See the attached Figure 7 to the attached Figure 14 as shown. The actuator 30 has a carrier 300 and a tensioning assembly A. The carrier 300 is a vertically placed annular body, that is, the axial direction of the carrier 300 is horizontal for the workpiece to be sleeved, so that multiple workpieces can be stacked; the tensioning assembly A is composed of multiple tensioning blocks A301. The multiple tensioning blocks A301 are arranged in a ring on the carrier 300, and the multiple tensioning blocks A301 can also reciprocate radially along the carrier 300 to move away from each other to tension and fix the workpiece sleeved on the carrier 300, or to move closer to each other to release the fixation of the workpiece sleeved on the carrier 300; in addition, when the multiple tensioning blocks A301 are in a state of moving away from each other, the carrier 300 can also rotate around its own axis to drive the workpiece fixed thereon to rotate by a set angle, so as to stagger the magnets on the multiple stacked workpieces.

[0046] Further preferably, the layering mechanism 3 further has a mounting plate base 31, a driving mechanism A and a driving mechanism B. The mounting plate base 31 is used to carry the actuator 30, the driving mechanism A and the driving mechanism B. The driving mechanism A can drive the carrier 300 to rotate around its own axis, and the driving mechanism B can drive the multiple tensioning blocks A301 to reciprocate radially along the carrier 300.

[0047] Specifically, the structure for enabling the driving mechanism A to drive the carrier 300 to rotate around its own axis is: refer to the attached Figure 10 and the attached Figure 11 as shown. The driving mechanism A has a transmission shaft 320 rotatably mounted on the mounting plate base 31 through a bearing seat and a power assembly A capable of driving the transmission shaft 320 to rotate around its own axis. The carrier 300 is coaxially arranged with the transmission shaft 320 and fixedly connected to an axial end of the transmission shaft 320, that is: the power assembly A outputs power and is transmitted through the transmission shaft 320 to drive the carrier 300 to rotate around its own axis.

[0048] Regarding the specific structure of the power assembly A, various implementation structures can be adopted according to production requirements. For example: refer to the attached Figure 11As shown, the power assembly A can be a combination of a motor A321, a pair of synchronous pulleys 322, and a synchronous belt 323. The motor A321 is fixedly installed on the mounting plate seat 31. A pair of the synchronous pulleys 322 are respectively fixedly sleeved on the power output shaft of the motor A321 and the transmission shaft 320, and the pair of synchronous pulleys 322 are also connected by the synchronous belt 323. Alternatively, the power assembly A can be a combination of a motor A321, a worm, and a worm gear. The motor A321 is fixedly installed on the mounting plate seat 31. One end of the worm is positioned and connected to the power output shaft of the motor A321 through a coupling. The worm gear is fixedly sleeved on the transmission shaft 320, and the worm gear is also meshed with the worm; etc. In the field of automation, there are many types of power assemblies that can provide rotational power and are widely used, which are well-known technical means for those skilled in the field of automation, so they will not be elaborated one by one here.

[0049] The specific structure for enabling the drive mechanism B to drive a plurality of the tensioning blocks A301 to reciprocate radially along the carrier 300 is as follows: See attached Figure 12 As shown, a plurality of receiving cavities respectively extending radially are provided in the annular wall of the carrier 300, and the plurality of receiving cavities are also arranged at equal intervals in the circumferential direction of the carrier 300; in addition, the plurality of receiving cavities respectively open on the inner and outer side walls of the carrier 300 to form a plurality of inner sockets 3000 and a plurality of outer mounting ports 3001; a plurality of the tensioning blocks A301 are respectively movably arranged in the plurality of outer mounting ports 3001; See attached Figure 10 to attached Figure 14As shown, the driving mechanism B has a driven shaft 330, a plurality of driven blocks A331, a plurality of driven blocks B332, and a power assembly B. Among them, the driven shaft 330 is axially slidably inserted into the transmission shaft 320 along the axial direction of the transmission shaft 320. Specifically, by providing a sliding strip and a sliding groove on the outer wall of the driven shaft 330 and the inner wall of the transmission shaft 320 that are in concave-convex fit and extend along their axial directions respectively, the sliding connection between the driven shaft 330 and the transmission shaft 320 can be achieved; one axial end of the driven shaft 330 also extends out of one axial end of the transmission shaft 320 and is simultaneously inserted into the inner hole 3002 of the carrier 300; one ends of the plurality of driven blocks A331 are all placed in the inner hole 3002, and inclined sliding grooves 3310 that extend axially relative to the carrier 300 are respectively provided at one ends of the plurality of driven blocks A331. The other ends of the plurality of driven blocks A331 are respectively slidably inserted into the corresponding plurality of receiving cavities from the plurality of inner sockets 3000. At the same time, the other ends of the plurality of driven blocks A331 are respectively fixedly connected to the plurality of tensioning blocks A301. In addition, elastic members for providing elastic restoring forces to the driven blocks A331 are respectively connected between the plurality of driven blocks A331 and one axial end of the driven shaft 330. Specifically, a sleeve 333 is fixedly sleeved on one axial end of the driven shaft 330. The elastic member uses a tension spring, and both ends of each tension spring are respectively fixedly connected to the sleeve 333 and one end of the driven block A331; or elastic members for providing elastic restoring forces to the driven blocks A331 are respectively connected between the plurality of driven blocks A331 and the plurality of receiving cavities. Specifically, the elastic member uses a spring, and both ends of the spring are respectively elastically abutted against the other end of the driven block A331 and the inner wall of the receiving cavity; one ends of the plurality of driven blocks B332 are respectively fixedly connected to one axial end of the driven shaft 330. Specifically, one ends of the plurality of driven blocks B332 are respectively fixedly connected to the sleeve 333; inclined sliding strips 3320 that extend axially relative to the carrier 300 are respectively provided at the other ends of the plurality of driven blocks B332, and the plurality of inclined sliding strips 3320 are respectively slidably arranged in the plurality of inclined sliding grooves 3310; thus, when the driven shaft 330 moves forward axially along the transmission shaft 320 under the drive of the power assembly B, the driven shaft 330 can drive the plurality of driven blocks B332 to move synchronously therewith, and further drive the plurality of driven blocks A331 to move radially outward along the carrier 300 to realize the mutual separation of the plurality of tensioning blocks A301;When the driven shaft 330 retracts axially in the reverse direction along the transmission shaft 320 under the drive of the power assembly B, the driven shaft 330 can drive a plurality of the driven blocks B332 to move synchronously therewith. At that time, a plurality of the driven blocks A331 can move radially inward along the carrier 300 under the elastic restoring force of the elastic member, so as to realize the mutual approach of a plurality of the tensioning blocks A301.;

[0050] Regarding the specific structure of the power assembly B, the following structure can be preferably adopted: Define the axial direction of the carrier 300 as the front-back direction; One axial end of the transmission shaft 320 extends in front of the mounting plate seat 31, that is, the carrier 300 is arranged in front of the mounting plate seat 31, and the other axial end of the transmission shaft 320 extends behind the mounting plate seat 31; The motor A321 in the power assembly A is fixedly connected to the rear side of the mounting plate seat 31 through a connecting bracket;

[0051] See attached Figure 10 and attached Figure 11 As shown, the power assembly B has an auxiliary fixed plate A334, an auxiliary movable plate A335, a plurality of guide posts A extending in the front-back direction, and a cylinder A336. The auxiliary fixed plate A334 is vertically and fixedly connected to the rear side of the mounting plate seat 31, and a guide rail A extending in the front-back direction is fixedly laid on the auxiliary fixed plate A334; The auxiliary movable plate A335 is arranged behind the mounting plate seat 31 and is movably connected to the mounting plate seat 31 through a plurality of the guide posts A. At the same time, the auxiliary movable plate A335 is also slidably connected to the guide rail A. Specifically: The rear ends of a plurality of the guide posts A are fixedly connected to the auxiliary movable plate A335, and the front ends of a plurality of the guide posts A are respectively movably connected to the mounting plate seat 31 through guide sleeves; The cylinder A336 is installed on the auxiliary fixed plate A334, and the piston rod of the cylinder A336 can drive the auxiliary movable plate A335 to reciprocate in the front-back direction; In addition, the other axial end of the driven shaft 330 also extends outside the other axial end of the transmission shaft 320 and is rotatably arranged on the auxiliary movable plate A335. Of course, in order to accurately control the movement of the driven shaft 330, the power assembly B is also equipped with sensing components such as a limiter and a position sensor.

[0052] Secondly, the specific structures of the first material receiving and docking mechanism 1 and the second material receiving and docking mechanism 2 will be described.

[0053] See attached Figure 2 to attached Figure 6As shown, the first material receiving and docking mechanism 1 has a material receiving carrier 10 and a pushing plate 11. The material receiving carrier 10 is a vertically placed annular body for the workpiece conveyed by the previous process to be sleeved on. At the same time, the material receiving carrier 10 is also arranged opposite to and coaxially with the carrier 300. In addition, the outer diameter dimensions of the material receiving carrier 10 and the carrier 300 are the same. The pushing plate 11 is movably sleeved outside the material receiving carrier 10 and can perform horizontal reciprocating movement along the axial direction of the material receiving carrier 10.

[0054] See the appendix Figure 7 to the appendix Figure 11 As shown, the second material receiving and docking mechanism 2 has an annular material receiving plate 20. The material receiving plate 20 is sleeved outside the carrier 300 and can perform reciprocating movement along the axial direction of the carrier 300. That is, the material receiving plate 20 can perform relative movement with the pushing plate 11 to cooperate in transferring the workpiece sleeved on the material receiving carrier 10 to the carrier 300, and the inner diameter dimensions of the material receiving plate 20 and the pushing plate 11 are the same.

[0055] Further preferably, the first material receiving and docking mechanism 1 also has a tensioning assembly B, a driving mechanism C, and a driving mechanism D. Among them, the tensioning assembly B is composed of at least two tensioning blocks B12. At least two of the tensioning blocks B12 are arranged at intervals along the circumferential direction of the material receiving carrier 10 on the material receiving carrier 10, and at least two of the tensioning blocks B12 can also perform reciprocating movement along the radial direction of the material receiving carrier 10 under the drive of the driving mechanism C, so that at least two of the tensioning blocks B12 move away from each other to realize tensioning and fixing of the workpiece sleeved on the material receiving carrier 10, or at least two of the tensioning blocks B12 move closer to each other to realize releasing the fixing of the workpiece sleeved on the material receiving carrier 10. The driving mechanism D can drive the pushing plate 11 to perform horizontal reciprocating movement along the axial direction of the material receiving carrier 10.

[0056] Specifically, there are two tensioning blocks B12, and the specific structure of installing the two tensioning blocks B12 on the material receiving carrier 10 is: see the appendix Figure 5 As shown, two chutes 100 respectively extending radially are provided on the peripheral wall of the material receiving carrier 10. The two chutes 100 are also arranged at intervals along the circumferential direction of the material receiving carrier 10, and the two tensioning blocks B12 are respectively slidably arranged in the two chutes 100.

[0057] The specific structure for realizing that the driving mechanism C can drive the two tensioning blocks B12 to perform reciprocating movement along the radial direction of the material receiving carrier 10 is: see the appendix Figure 4 to the appendix Figure 6As shown, the driving mechanism C includes a cylinder B130, a transmission block A131, two transmission blocks B132, and two push rods 133. Among them, the cylinder B130 and the material receiving carrier 10 are arranged at an axial interval along the axis of the material receiving carrier 10 (the axial direction of the material receiving carrier 10 is the horizontal direction). The piston rod of the cylinder B130 can extend and retract along the axis of the material receiving carrier 10 and point to the material receiving carrier 10. The transmission block A131 is fixedly connected to the piston rod of the cylinder B130. On the side of the transmission block A131 facing away from the cylinder B130, there are also two inclined surfaces A1310 extending radially along the material receiving carrier 10. At the same time, the extending directions of the two inclined surfaces A1310 are respectively parallel to the extending directions of the two chutes 100. The two transmission blocks B132 are respectively formed with inclined surfaces B1320, and the two inclined surfaces B1320 are respectively in contact with and slidably connected to the two inclined surfaces A1310. And between the two transmission blocks B132 and the transmission block A131, there are respectively connected with springs (not shown in the figure) that can provide elastic restoring forces to the transmission blocks B132. The two push rods 133 respectively extend along the axis of the material receiving carrier 10, and one ends of the two push rods 133 are respectively fixedly connected to the two transmission blocks B132, and the other ends of the two push rods 133 are respectively connected to the two tensioning blocks B12. In this way, when the piston rod of the cylinder B130 extends along the axis of the material receiving carrier 10, it will drive the two transmission blocks B132 to move away from each other, thereby driving the two push rods to move away from each other, and driving the two tensioning blocks B12 to move away from each other, that is, making the two tensioning blocks B12 move radially outward along the material receiving carrier 10. At this time, the two tensioning blocks B12 can realize the tensioning and fixing of the workpiece sleeved on the material receiving carrier 10. When the piston rod of the cylinder B130 retracts along the axis of the material receiving carrier 10, the two transmission blocks B132 move closer to each other under the action of the restoring force of the spring, thereby driving the two push rods to move closer to each other, and driving the two tensioning blocks B12 to move closer to each other, that is, making the two tensioning blocks B12 move radially inward along the material receiving carrier 10. At this time, the two tensioning blocks B12 can realize the release of the fixing of the workpiece sleeved on the material receiving carrier 10.

[0058] The specific structure for enabling the driving mechanism D to drive the push plate 11 to perform horizontal reciprocating movement along the axis of the material receiving carrier 10 is as follows: See Appendix Figure 2 to Appendix Figure 4As shown, the driving mechanism D has a cylinder C140 and a plurality of guide columns B141. The cylinder C140 and the material receiving carrier 10 are arranged at an axial interval along the material receiving carrier 10. The piston rod of the cylinder C140 can be telescoped along the axis of the material receiving carrier 10, and a transmission plate 142 is also connected to the piston rod of the cylinder C140. The plurality of guide columns B141 all extend along the axis of the material receiving carrier 10, and the plurality of guide columns B141 are respectively fixedly connected between the transmission plate 142 and the material pushing plate 11. In this way, by the piston rod of the cylinder C140 telescoping along the axis of the material receiving carrier 10 and transmitting power through the transmission plate 142 and the guide columns B141, the material pushing plate 11 can be driven to reciprocate axially along the material receiving carrier 10. Of course, in order to accurately control the movement of the material pushing plate 11, sensing components such as a limiter and a position sensor are also configured.

[0059] Further preferably, the first material receiving docking mechanism 1 further has a driving mechanism E, and the driving mechanism E can drive the material receiving carrier 10 and the material pushing plate 11 to move closer to or away from the carrier 300 together. That is: the driving mechanism E is used to perform a large-stroke adjustment on the distance between the material receiving carrier 10 / the material pushing plate 11 and the carrier 300 / the material receiving plate 20.

[0060] Specifically, see Attachment Figure 2 to Attachment Figure 4 As shown, the driving mechanism E has a base 150, a mounting seat 151 and a linear driving component. A slide rail A extending along the axis of the material receiving carrier 10 is positioned and laid on the upper side of the base 150. The mounting seat 151 is slidably mounted on the slide rail A through a slider, and the linear driving component can drive the mounting seat 151 to move on the slide rail A. Regarding the linear driving component, various implementation manners can be adopted. For example: a motor B152 and a lead screw module combination can be adopted, or a driving cylinder can be adopted, or a combination of a motor B152, a synchronous pulley and a synchronous belt can be adopted, etc.; they are common technical means in the automation field, so they will not be elaborated one by one here.

[0061] In addition, the connection relationships between the above-mentioned material receiving carrier 10, driving mechanism C and driving mechanism D and the driving mechanism E are: see Attachment Figure 4As shown, the mounting base 151 has a bottom plate 1510 slidably mounted on the slide rail A and a mounting vertical plate 1511 vertically and fixedly connected to the bottom plate 1510. The bottom plate 1510 is positioned and connected to the power output end of the linear drive assembly. The material receiving carrier 10 is fixedly arranged on one side of the mounting vertical plate 1511 facing the carrier 300. The cylinder B130 in the drive mechanism C is fixedly arranged on the bottom plate 1510, and the two push rods 133 respectively pass through the mounting vertical plate 1511 movably. The cylinder C140 in the drive mechanism D is fixedly arranged on the side of the mounting vertical plate 1511 facing away from the material receiving plate 20. The transmission plate 142 is movably arranged beside the side of the cylinder C140 facing away from the mounting vertical plate 1511 and is fixedly connected to the piston rod of the cylinder C140. One ends of the plurality of guide posts B141 respectively pass through the mounting vertical plate 1511 through guide sleeves and are then respectively fixedly connected to the pushing plate 11.

[0062] In addition, according to production requirements, the material receiving carrier 10 can be configured into two groups. Correspondingly, the pushing plate 11, the tensioning assembly B, the drive mechanism C, and the drive mechanism D are also configured into two groups, but the drive mechanism E can continue to remain as one group. In addition, in the case where the carrier 300 / the material receiving plate 20 is one group, in order to make the two groups of material receiving carriers 10 better cooperate with the carrier 300 / the material receiving plate 20 to work, a drive mechanism F (not shown in the figure) can also be configured. The drive mechanism F can drive the drive mechanism E to move in the horizontal direction (such as the left-right direction) perpendicular to the axial direction of the material receiving carrier 10, so that the two groups of material receiving carriers 10 can be selectively cooperated with the carrier 300 / the material receiving plate 20 to work. For the specific implementation structure of the drive mechanism F, reference can be made to the drive mechanism E, and it is only necessary to configure a bottom substrate and a linear drive assembly. A slide rail B extending in the horizontal direction perpendicular to the axial direction of the material receiving carrier 10 is fixedly laid on the bottom substrate. The base 150 is slidably mounted on the slide rail B, and the linear drive assembly can drive the base 150 to move on the slide rail B.

[0063] Further preferably, the axial direction of the carrier 300 is defined as the front-rear direction. The carrier 300 is arranged in front of the mounting plate seat 31, and the material receiving carrier 10 is arranged in front of the carrier 300.

[0064] The second material receiving docking mechanism 2 also has a drive mechanism G, see attachment Figure 8 and attachment Figure 10As shown in the figure, the driving mechanism G includes an auxiliary fixed plate B210, an auxiliary movable plate B211, a power assembly C, and a plurality of connecting rods A212 and connecting rods B213 respectively extending in the front-rear direction. The auxiliary fixed plate B210 is fixedly connected to the rear side of the mounting plate seat 31 through the plurality of connecting rods A212. The auxiliary movable plate B211 is movably sleeved on the connecting rods A212. At the same time, the auxiliary movable plate B211 is also fixedly connected to the material receiving plate 20 through the plurality of connecting rods B213. Of course, the connecting rods B213 are movably connected to the mounting plate seat 31. The power assembly C is mounted on the auxiliary fixed plate B210 and can drive the auxiliary movable plate B211 to move and position in the front-rear direction, thereby realizing driving the material receiving plate 20 to move and position in the front-rear direction.

[0065] Regarding the power assembly C, various implementation structures can be adopted according to production requirements. For example: refer to the attached Figure 8 and the attached Figure 10 As shown in the figure, the power assembly C can adopt a combination of a motor C214, a gear set, and a lead screw module 215. The motor C214 is mounted on the auxiliary fixed plate B210. The lead screw of the lead screw module 215 is rotatably connected between the auxiliary fixed plate B210 and the mounting plate seat 31. The transmission nut of the lead screw module 215 is positioned and connected to the auxiliary movable plate B211; or the power assembly C can adopt a cylinder. The cylinder is mounted on the auxiliary fixed plate B210. The piston rod of the cylinder is positioned and connected to the auxiliary movable plate B211; and so on. In the field of automation, there are many types of power assemblies that can provide linear movement power and are widely used, which are well-known technical means for those skilled in the field of automation. Therefore, they will not be elaborated one by one here.

[0066] In addition, the silicon steel sheet magnet laminating device further includes a correction assembly for correcting the magnets on the workpieces. See the attached Figure 7 to the attached Figure 10 As shown in the figure, the correction assembly has a plurality of PIN needles 4. The plurality of PIN needles 4 are arranged in a circular array and elastically mounted on the front side of the mounting plate seat 31. Specifically: a plurality of through holes are arranged in a circular array on the mounting plate seat 31. The plurality of PIN needles 4 are all elastically mounted in the plurality of through holes through spring members. In addition, a plurality of avoidance holes are arranged in a circular array on the material receiving plate 20. The plurality of avoidance holes correspond to the plurality of PIN needles 4 one by one for the plurality of PIN needles 4 to pass through movably, that is, to avoid the PIN needles 4.

[0067] In addition, to adapt to other workstations in the production line, the silicon steel sheet magnet layering device is also equipped with a gantry 5 and a lifting device. The columns of the gantry 5 are fixedly laid with vertically extending slide rails C. The mounting plate seat 31 is slidably mounted on the slide rails C. The lifting device can drive the mounting plate seat 31 to move up and down on the gantry 4. Of course, the lifting device can adopt a combination of a motor and a KK module, or a lifting hydraulic cylinder, etc. These are common technical means in the field of automation and will not be described in detail here.

[0068] In order to adapt to the operation of the injection molding machine in the subsequent process, a finished product loading and unloading mechanism 6 is also installed on the mounting plate seat 31. The specific structure of the finished product loading and unloading mechanism 6 is partially the same as the first material receiving and docking mechanism 1, that is, the finished product loading and unloading mechanism 6 includes the material receiving carrier 10, the pushing plate 11, the tensioning assembly B, the driving mechanism C and the driving mechanism D in the first material receiving and docking mechanism 1; that is to say, the finished product loading and unloading mechanism 6 has the functions of receiving, tensioning, fixing and pushing the workpiece.

[0069] In combination with the above description of the specific structure of the silicon steel sheet magnet stratification device, the working method of the silicon steel sheet magnet stratification device is described below.

[0070] The working method of the silicon steel sheet magnet layering device is as follows:

[0071] S1: Calibrate the magnet on the workpiece;

[0072] S11: The robot in the previous process places multiple workpieces one by one on the receiving carrier 10, and then the driving mechanism E operates to drive the receiving carrier 10 and the pusher plate 11 to move toward the carrier 300 until the gap between the receiving carrier 10 and the carrier 300 meets the processing requirements;

[0073] Description: The preceding process involves simultaneously inserting magnets into the multi-layer silicon steel annular sheets. This process is relatively easy to implement, for example, by using a fixture to stack and secure multiple silicon steel annular sheets on a processing platform, and then using a combination of a manipulator and a gripper to grip the magnets and insert them into the multi-layer silicon steel annular sheets. Since the preceding process is not protected by this patent, it will not be described in detail here.

[0074] S12: The drive mechanism D operates to drive the pusher plate 11 to move towards the carrier 300 (which can be understood as moving backward), and the drive mechanism G operates to drive the receiving plate 20 to move towards the receiving carrier 10 (which can be understood as moving forward). When the pusher plate 11 and the receiving plate 20 are respectively pressed against the workpieces (it can be understood that the pusher plate 11 is pressed against the foremost workpiece, and the receiving plate 20 is pressed against the rearmost workpiece), the pusher plate 11 and the receiving plate 20 move backward together to transfer a plurality of workpieces onto the carrier 300, and the magnet on the rearmost workpiece is pressed against the PIN pin 4. At this time, the reference calibration of the magnets on the plurality of workpieces is completed. Note: Since the plurality of workpieces are stacked, when the magnet on the rearmost workpiece is pressed and calibrated by the PIN pin 4, correspondingly, the magnets on other workpieces will also be calibrated accordingly;

[0075] S13: When the reference calibration of the plurality of workpieces is completed, the pusher plate 11 and the receiving plate 20 move forward together to transfer the calibrated plurality of workpieces onto the receiving carrier 10; then the drive mechanism C operates to drive the tensioning assembly B to tension and fix the plurality of workpieces, and the receiving plate 20 moves backward to reset;

[0076] S2: Perform a layering operation on the workpieces;

[0077] S21: Driven by the drive mechanism D and the drive mechanism G, the pusher plate 11 and the receiving plate 20 are respectively pressed against the plurality of workpieces again, and then the pusher plate 11 and the receiving plate 20 move backward together. After the rearmost workpiece (for the convenience of description, it is called workpiece A) is transferred onto the carrier 300, the drive mechanism D and the drive mechanism G both suspend driving. Correspondingly, the drive mechanism C drives the tensioning assembly B to tension and fix the remaining workpieces placed on the receiving carrier 10, and the drive mechanism B drives the tensioning assembly A to tension and fix workpiece A;

[0078] S22: The drive mechanism A drives the transmission shaft 320 and the carrier 300 to rotate to drive the magnet on workpiece A to rotate by an angle A; then the drive mechanism B drives the tensioning assembly A to release the fixation of workpiece A, and the drive mechanism C drives the tensioning assembly B to release the fixation of the remaining workpieces;

[0079] S23: Driven by the driving mechanism D and the driving mechanism G, the pusher plate 11 and the receiving plate 20 move backward together again. After the workpiece B in front of the workpiece A is transferred onto the carrier 300, the driving mechanism D and the driving mechanism G both pause driving. Correspondingly, the driving mechanism C drives the tensioning assembly B to tension and fix the remaining workpieces placed on the receiving carrier 10, and the driving mechanism B drives the tensioning assembly A to tension and fix the workpiece A and the workpiece B; Note: Since the workpiece A has been rotated, at this time, the magnets on the workpiece B and the workpiece A are staggered.

[0080] S24: The driving mechanism A drives the transmission shaft 320 and the carrier 300 to rotate, so as to drive the magnets on the workpiece A and the workpiece B to rotate by an angle B; then the driving mechanism B drives the tensioning assembly A to release the fixation of the workpiece A and the workpiece B, and the driving mechanism C drives the tensioning assembly B to release the fixation of the remaining workpieces.

[0081] S25: Repeat S23 and S24 until the last workpiece is transferred onto the carrier 300; Note: After the last workpiece is transferred onto the carrier 300, it can be selected whether to rotate according to product requirements; the layered operation of multiple workpieces is completed to obtain semi-finished products.

[0082] In addition, the cooperation mode of this silicon steel sheet magnet layering device with other workstations in the production line is as follows: after the layering operation is completed, the lifting device works to lift the mounting plate seat 31 and each mechanism / component thereon to the transfer module of the injection molding machine. Then, the tensioning assembly A releases the fixation of multiple workpieces, and the receiving plate 20 pushes multiple workpieces into the transfer module. The transfer module then transfers the workpieces into the injection molding machine mold for injection molding; after the injection molding is completed, the transfer module transfers the finished products to the finished product loading and unloading mechanism 6.

[0083] In summary, the structure of the silicon steel sheet magnet lamination device of the present invention is novel and reasonable, which can replace manual operation to automatically stack and laminate multiple layers of silicon steel ring sheets and automatically stagger and laminate magnets. It not only has high production efficiency, reliable production quality and high production safety, but also greatly reduces the labor cost and labor intensity. In addition, when the silicon steel sheet magnet lamination device of the present invention is working, it is necessary to complete the operation of inserting the magnet into the silicon steel ring sheet in the previous process. However, since there is no need to consider the factor of magnet staggering when inserting the magnet in the previous process, the operation of the previous process becomes very simple and easy to implement. For example, a combination of a manipulator and a gripper can be used to insert magnets into multiple stacked silicon steel ring sheets at the same time, which is not only simple and easy to operate, but also has high production efficiency and high production accuracy. In short, the configuration of the silicon steel sheet magnet lamination device of the present invention is beneficial to simplifying the operation methods of other processes associated therewith, thereby improving the production efficiency and production accuracy of the entire production line. In addition, the silicon steel sheet magnet lamination device of the present invention is not only applicable to the processing of motor rotors, but also applicable to the production of transformer cores, etc., and has good versatility.
