Description

Technical Field

[0001] The invention relates to the technical field of iron core laminations, and in particular to a rotor iron core lamination device and a lamination method. Background Art

[0002] The rotor core is the core component of the motor, mainly used to transmit mechanical energy and electrical energy, and is the basis for the normal operation of the motor. The production of the core is generally divided into two types: lamination production and integral production.

[0003] As far as lamination production is concerned, the performance of the core made by lamination is relatively good, because each layer of iron sheet has the same magnetic permeability and resistivity, and no eddy current and heat loss will occur under the magnetic field, thereby improving the efficiency of the motor.

[0004] When laminating the rotor core, the cut silicon steel sheets are usually stacked together manually or by a robot. During the lamination process, the silicon steel sheets need to be coated with glue by a gluing device, which requires multiple devices to cooperate with each other to achieve lamination. In addition, since the production and lamination of silicon steel sheets are carried out separately, misalignment of the silicon steel sheets may occur during the lamination process.

[0018] It also includes a fixed rod fixedly installed in the workbench, a sliding sleeve is slidably installed on the fixed rod, a connecting plate fixedly connected to the threaded sleeve is rotatably installed on the sliding sleeve, and a supporting assembly is arranged on the connecting plate.

[0019] As a further solution of the present invention: the supporting assembly includes a rotating sleeve rotatably mounted on the connecting plate and symmetrically arranged, a movable rod is slidably mounted inside the rotating sleeve, the movable rod is rotatably connected to the supporting plate, a second groove is opened on the side wall of the rotating sleeve, and a second protrusion is fixed on the movable rod to slideably engage with the second groove.

[0020] As a further solution of the present invention: the strength control mechanism includes a vertical groove and a first spiral groove opened on the circumferential outer wall of the fixed rod, a first limit block slidingly engaged with the vertical groove and the first spiral groove is fixed to the inner wall of the sliding sleeve, a belt connected to the rotating sleeve is sleeved on the sliding sleeve, and a sliding assembly is provided on the rotating sleeve.

[0022] A rotor core lamination method comprises the following steps:

[0023] Step 1: Place the required stacked silicon steel sheets on the support plate, and drive the cutting disc and the pressing and fixing mechanism to move under the action of the lifting assembly;

[0024] Step 2: Under the action of the glue delivery component, glue is delivered to the surface of the silicon steel sheet. When the pressing and fixing mechanism moves to abut against the silicon steel sheet, the silicon steel sheet will be fixed. At this time, the cutting disk continues to move and cuts the silicon steel sheet;

[0025] Step 3: When the cutting disc pushes the cut silicon steel sheet to the position matching with the support disc, the silicon steel sheet will be placed on the support disc, and under the action of the stacking support mechanism, the support disc is controlled to move in a direction away from the support plate;

[0026] Step 4: Repeat the above steps so that the cut silicon steel sheets are bonded to each other by glue to form a whole.

[0028] Among them, the pressing and fixing mechanism first contacts the silicon steel sheet, and when the pressing and fixing mechanism abuts against the silicon steel sheet, the silicon steel sheet will be fixed to ensure that when the subsequent cutting disc moves to contact the silicon steel sheet, the cutting disc can cut the completely fixed silicon steel sheet, and the silicon steel sheet will not shift, thereby avoiding the problem of poor cutting quality of the silicon steel sheet. After the cutting is completed, the silicon steel sheet separated from the sheet material will fall onto the support disc through the through hole. Repeating the above steps can continuously obtain multiple finished silicon steel sheets, and the multiple finished silicon steel sheets are dropped in sequence to ensure that the silicon steel sheets will not be misplaced when stacking.

[0029] Before stacking multiple formed silicon steel sheets, glue delivery components can be used to pump glue to the surface of the silicon steel sheets to ensure that after the silicon steel sheets are cut and formed, the silicon steel sheets that are cut in sequence can be bonded to each other by glue during the stacking process.

[0030] In addition, the present invention also takes into account that as the number of silicon steel sheet stacks increases, the overall weight and height will increase, and the stability of the stack will decrease; therefore, a stack support mechanism is provided, under the action of the stack support mechanism, the support disk moves in a direction away from the support plate, ensuring that the distance between the top silicon steel sheet and the through hole remains unchanged, and at the same time, under the action of the strength control mechanism, the supporting force on the support disk can be increased synchronously when the number of stacked silicon steel sheets increases, to ensure that the silicon steel sheets are subjected to a certain downward pressure during the stacking process, thereby ensuring the best stacking quality.

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0044] See also Figure 1-Figure 10 In an embodiment of the present invention, a rotor core lamination device includes:

[0045] A workbench 1, and a support plate 2 fixedly mounted on the workbench 1, wherein symmetrically arranged guide posts 3 are fixed on the support plate 2, a lifting plate 4 is fixed on one end of the guide posts 3 away from the support plate 2, and a through hole 201 is opened on the support plate 2;

[0046] Also includes:

[0047] See also Figure 1-Figure 3 , a lifting assembly is arranged on the lifting plate 4 and connected to the guide column 3, the lifting assembly includes a guide sleeve 8 slidably mounted on the guide column 3, a movable plate 9 is fixed on the guide sleeve 8, the movable plate 9 is fixedly connected to the cutting disk 14, and a cylinder 7 fixedly connected to the movable plate 9 is fixed on the lifting plate 4.

[0048] In detail, the support plate 2 is rotatably mounted with a first guide roller 5 and a second guide roller 6, and the first guide roller 5 and the second guide roller 6 are symmetrically arranged, so that the molded silicon steel sheet can be wound around the first guide roller 5 and the second guide roller 6, so that the silicon steel sheet is placed on the support plate 2, and a certain gap is left between the silicon steel sheet and the support plate 2. When lamination is required, the silicon steel sheet only needs to be cut by the cutting disk 14. Therefore, in the initial state, under the action of the cylinder 7, the movable plate 9 is located at the end of the stroke toward the support plate 2. When the cylinder 7 is working, it drives the movable plate 9 to move toward the support plate 2, thereby driving the guide sleeve 8 to move along the length direction of the guide column 3. The guide sleeve 8 and the guide column 3 have a guiding function, which can ensure that the movable plate 9 will not deviate during movement. The movable plate 9 will also drive the pressing and fixing mechanism and the cutting disk 14 to move, so as to press and cut the silicon steel sheet.

[0049] Preferably, before the silicon steel sheets are stacked, the previous process has punched the sheets conveyed to the support plate 2 so that the sheets are punched into the required shape and size. When the sheets move to the position that cooperates with the cutting disk 14, the silicon steel sheets only need to be cut out from the sheets for stacking.

[0050] See also Figure 1-Figure 3 , Fig. 9 , Fig.10The lifting component is connected to a cutting disc 14, and a pressing and fixing mechanism is provided on the lifting component. The lifting component can drive the cutting disc 14 and the pressing and fixing mechanism to move along the length direction of the guide column 3. The pressing and fixing mechanism includes a support sleeve 10 fixedly mounted on the movable plate 9 and symmetrically arranged, a support rod 11 is slidably mounted in the support sleeve 10, and a pressure ring 12 is fixed at one end of the support rod 11 away from the support sleeve 10, and an elastic component connected to the support rod 11 is provided on the support sleeve 10, wherein the elastic component includes a first card groove 1001 opened on the side wall of the support sleeve 10, and a first protrusion 1101 slidably engaged with the first card groove 1001 is fixed on the support rod 11, and a first spring 13 is sleeved on the support sleeve 10 and the support rod 11, and the two ends of the first spring 13 are respectively abutted against the movable plate 9 and the pressure ring 12.

[0051] It should be noted that, in the initial state, the first spring 13 is in a compressed state, so that the support rod 11 is located at the end of the stroke away from the support sleeve 10, so that the first protrusion 1101 is located at the end of the stroke on the side of the first slot 1001. At this time, the distance between the pressure ring 12 and the movable plate 9 is the largest. When the silicon steel sheet needs to be laminated, the movement of the sheet is controlled under the action of the first guide roller 5 and the second guide roller 6. Under the action of the cylinder 7, the movable plate 9 is controlled to move, thereby driving the support sleeve 10 to move. The support sleeve 10 will control the movement of the support rod 11 through the first spring 13 to drive the pressure ring 12 to move toward the support plate 2. The movable plate 9 will also drive the cutting disk 14 moves. When the pressure ring 12 moves to the position in contact with the silicon steel sheet, the silicon steel sheet is fixed between the pressure ring 12 and the support plate 2 under the action of the pressure ring 12 and the support plate 2, ensuring that the silicon steel sheet will not shift during the cutting process. At this time, the movable plate 9 continues to move, so that the size of the support sleeve 10 and the support rod 11 is increased to compress the first spring 13. The movable plate 9 also drives the cutting disk 14 to move. When the cutting disk 14 moves to the position in contact with the silicon steel sheet, the silicon steel sheet is cut under the action of the cutting disk 14, and the cut silicon steel sheet is transported to the workbench 1 through the through hole 201, so that the silicon steel sheet is placed on the support disk 25.

[0052] Preferably, in the initial state, the cutting disk 14 is located between the pressure ring 12 and the support plate 2. When the pressure ring 12 is in contact with the silicon steel sheet, the cutting disk 14 has not yet been in contact with the silicon steel sheet. Therefore, it can be ensured that the silicon steel sheet will not shift and cause deformation during cutting. At the same time, after the pressure ring 12 is in contact with the silicon steel sheet, the first guide roller 5 and the second guide roller 6 stop rotating to ensure that the silicon steel sheet will not move. When the cutting disk 14 is in contact with the silicon steel sheet, in cooperation with the through hole 201, the required silicon steel sheet is cut out from the sheet and falls into the workbench 1 through the through hole 201. When the cutting is completed, the cutting disk 14 and the pressure ring 12 are reset under the action of the cylinder 7. At this time, the first guide roller 5 and the second guide roller 6 rotate again, and the above steps are repeated, thereby achieving the effect of continuously cutting and stacking the sheets, and the silicon steel sheets will not be misplaced during the stacking process.

[0053] See also Figure 1 , Figure 2 , Figure 4 The glue delivery component is arranged on the support plate 2 and is used to deliver glue to the silicon steel sheet. The glue delivery component includes a storage box 15 fixedly mounted on the support plate 2, and a conduit 16 is fixed on the storage box 15. The support plate 2 is provided with a plurality of delivery holes 17 which are connected to the storage box 15 and are equidistantly distributed around the circumference.

[0054] Furthermore, the conduit 16 is connected to the glue pumping equipment. When the silicon steel sheet is placed on the support plate 2, the required glue can be pumped into the storage box 15 through the conduit 16. After the storage box 15 is filled with glue, the glue is pumped to the side of the silicon steel sheet facing the support plate 2 through the delivery hole 17 under the action of pressure. When the pumping is completed, the glue pumping stops. At this time, the silicon steel sheet can be cut. When the cutting is completed and the next required cutting position moves to the position that cooperates with the cutting disk 14, the glue is pumped again, and the above steps are repeated, so that after the silicon steel sheet is cut, the mutual bonding effect can be obtained during the stacking process. Since the delivery hole 17 is arranged at an angle, the glue will only be pumped to the cut silicon steel sheet, thereby avoiding the waste of glue and causing pollution to the silicon steel sheet.

[0055] See also Figure 4-Figure 8, a lamination support mechanism is arranged in the workbench 1, and a support plate 25 is connected to the lamination support mechanism, and the lamination support mechanism includes a screw rod 18 rotatably installed in the workbench 1, and a threaded sleeve 19 threadedly matched with the screw rod 18 is movably installed on the screw rod 18; it also includes a fixed rod 21 fixedly installed in the workbench 1, and a sliding sleeve 22 is slidably installed on the fixed rod 21, and a connecting plate 20 fixedly connected to the threaded sleeve 19 is rotatably installed on the sliding sleeve 22, and a supporting assembly is arranged on the connecting plate 20, wherein the supporting assembly includes a rotating sleeve 23 rotatably installed on the connecting plate 20 and symmetrically arranged, and a movable rod 24 is slidably installed in the rotating sleeve 23, and the movable rod 24 is rotatably connected to the support plate 25, and a second groove 2302 is opened on the side wall of the rotating sleeve 23, and a second protrusion 2401 slidably engaged with the second groove 2302 is fixed on the movable rod 24.

[0056] To go further, in the initial state, under the action of the screw rod 18, the threaded sleeve 19 is located at the end of the stroke toward the support plate 2, so that the distance between the rotating sleeve 23 and the support plate 2 is controlled to be minimum through the connecting plate 20. Under the action of the strength control mechanism, the movable rod 24 is located at the end of the stroke away from the rotating sleeve 23, so that the support disk 25 is placed in the through hole 201, and the distance between it and the silicon steel sheet placed above the support plate 2 is minimized. At this time, the second protrusion 2401 is located at the end of the stroke on the side of the second slot 2302. When the silicon steel sheets need to be stacked, under the action of the cutting disk 14, the cut silicon steel sheets enter the through hole 201 and fall onto the support disk 25.

[0057] Preferably, under the action of the cutting disk 14, the support disk 25 is pushed by the silicon steel sheet to move toward the connecting plate 20, so that the movable rod 24 moves a certain distance toward the rotating sleeve 23, so that the second protrusion 2401 slides in the second slot 2302, so as to ensure that the silicon steel sheet is subjected to a certain downward pressure when stacking, thereby ensuring that the silicon steel sheet coated with glue is tightly fitted. When the cutting disk 14 moves toward the initial position, at this time, the screw 18 rotates and drives the threaded sleeve 19 to move, thereby controlling the sliding sleeve 22 to move along the length direction of the fixed rod 21 through the connecting plate 20. The connecting plate 20 will also control the support disk 25 to descend to a certain height through the rotating sleeve 23 and the movable rod 24, and when this height is consistent with the thickness of a silicon steel sheet, the screw 18 stops rotating. At this time, the silicon steel sheet is stacked again through the cutting disk 14, and the above steps are repeated to achieve the stacking of the silicon steel sheets.

[0058] See also Figure 4-Figure 8The lamination support mechanism is connected to a strength control mechanism, and the lamination support mechanism can drive the support plate 25 to move in the vertical direction, and adjust the support force of the support plate 25 through the strength control mechanism, and the strength control mechanism includes a vertical groove 2101 and a first spiral groove 2102 provided on the outer wall of the circumference of the fixed rod 21, and a first limit block 2201 that is slidably engaged with the vertical groove 2101 and the first spiral groove 2102 is fixed on the inner wall of the sliding sleeve 22, and a first limit block 2201 that is slidably engaged with the vertical groove 2101 and the first spiral groove 2102 is sleeved on the sliding sleeve 22. The belt 28 is connected to the cylinder 23, and a sliding component is arranged on the rotating sleeve 23, wherein the sliding component includes a second spiral groove 2301 opened on the circumferential outer wall of the rotating sleeve 23, and a sliding plate 26 is slidably installed on the rotating sleeve 23, and a second limit block 2601 slidably connected to the second spiral groove 2301 is fixed on the inner wall of the sliding plate 26, and a second spring 27 is sleeved on the rotating sleeve 23 and the movable rod 24, and the two ends of the second spring 27 are respectively abutted against the support disk 25 and the sliding plate 26.

[0059] To elaborate, in the initial state, the first limit block 2201 is located at the end of the stroke of the vertical groove 2101 away from the first spiral groove 2102, and the second limit block 2601 is located at the end of the stroke of the second spiral groove 2301, so that the distance between the sliding plate 26 and the connecting plate 20 is minimized. At this time, the elastic potential energy of the second spring 27 is minimized. When the silicon steel sheets need to be laminated, as the thickness of the laminate increases, the threaded sleeve 19 and the sliding sleeve 22 will continue to move in the direction away from the support plate 2, thereby driving the first limit block 2201 to slide along the vertical groove 2101. At this time, the supporting force provided by the second spring 27 to the silicon steel sheet is greater than the gravity of the silicon steel sheet. When the first limit block 2201 breaks away from the vertical groove 2101 and enters the first spiral groove 210 2, the gravity of the silicon steel sheet will be greater than the supporting force provided by the second spring 27 to the support plate 25. Therefore, it is necessary to increase the elastic potential energy of the second spring 27. Under the action of the first limit block 2201 and the first spiral groove 2102, the sliding sleeve 22 is rotated, thereby driving the rotating sleeve 23 to rotate through the belt 28. The rotating sleeve 23 also drives the second spiral groove 2301 to move, and under the action of the second limit block 2601, the sliding plate 26 moves in a direction away from the connecting plate 20 to compress the second spring 27. Under the action of the second spring 27, the supporting force on the support plate 25 is increased to ensure that during the lamination process of the silicon steel sheets, the silicon steel sheets can always obtain a certain downward pressure, thereby ensuring the best lamination effect of the silicon steel sheets.

[0060] A rotor core lamination method comprises the following steps:

[0061] Step 1: Place the required laminated silicon steel sheets on the support plate 2, and drive the cutting disc 14 and the pressing and fixing mechanism to move under the action of the lifting assembly;

[0062] Step 2: Under the action of the glue delivery assembly, glue is delivered to the surface of the silicon steel sheet. When the pressing and fixing mechanism moves to abut against the silicon steel sheet, the silicon steel sheet will be fixed. At this time, the cutting disk 14 continues to move and cuts the silicon steel sheet;

[0063] Step 3: When the cutting disc 14 pushes the cut silicon steel sheet to the position matching with the support disc 25, the silicon steel sheet will be placed on the support disc 25, and under the action of the stacking support mechanism, the support disc 25 is controlled to move away from the support plate 2;

[0064] Step 4: Repeat the above steps so that the cut silicon steel sheets are bonded to each other by glue to form a whole. At the same time, as the number of silicon steel sheets increases, the supporting force of the support plate 25 can also be adjusted under the action of the strength control mechanism.
