Description
Apparatus and system for manufacturing self-adhesive coated motor cores Technical Field
[0001] This application relates to an apparatus and system for manufacturing self-adhesive coated motor cores, and more particularly to an apparatus and system for manufacturing self-adhesive coated motor cores using a vertical continuous thermosetting method. Background Technology
[0002] Electric vehicle (EV) motors have recently made significant progress in improving performance and reducing iron losses. In addition to continuously thinning the laminated core of the electrical steel (ES), manufacturing methods have shifted from riveting and welding to adhesive bonding. Many steel companies worldwide have responded promptly to the demands of the electric vehicle market by developing their own motor-adhesive coated (self-adhesive) ES strips.
[0003] In current technology, if electromagnetic steel sheets with self-adhesive coatings are to be manufactured into rivetless iron cores, they need to be stacked, positioned, pressurized, and heated to form an iron core. The most common manufacturing method in the industry is to first use punching and shearing equipment to process the raw materials into electromagnetic steel sheets of a specific shape, then collect the electromagnetic steel sheets and manually stack, position and lock them, and finally heat them to bond the stacked electromagnetic steel sheets together to form a complete iron core. This is mostly done by horizontal transverse conveying.
[0004] Furthermore, the manufacturing of laminated iron cores can generally be carried out using a rotary transverse conveying system. The laminated iron core, with an adhesive coating on its surface, is conveyed through a pressing device, measuring device, heating device, cooling device, and ejection device of the conveying system. This process presses each self-adhesive electromagnetic steel sheet into a predetermined position, followed by thermosetting. After the electromagnetic steel sheets are punched by the self-adhesive iron core punching and shearing unit, they need to undergo pressing, collection, stacking, positioning, heating, and cooling before being hot-pressed together to form the iron core.
[0005] However, this process shows that the entire self-adhesive core manufacturing equipment requires a large space and can only be used for the production of single products, and cannot meet customers' needs for small-batch and diverse laminated cores.
[0006] Therefore, in order to overcome the shortcomings and deficiencies in the prior art, it is necessary to provide an improved device and system for manufacturing self-adhesive coated motor cores to solve the problems existing in the prior art. Summary of the Invention
[0007] In view of this, the main objective of this application is to provide an apparatus and system for manufacturing self-adhesive coated motor cores, wherein the heating module and the cooling module are arranged outside the feed pipe, and the heating module is positioned above the cooling module, thereby shortening the operation time and improving the operation efficiency by vertically and continuously thermosetting the laminated core.
[0008] To achieve the above objectives, this application provides a system for manufacturing self-adhesive coated motor cores. The system includes a feeding unit, a pressing unit, a moving unit, a heating unit, a cooling unit, and a discharging unit. The feeding unit is electrically connected to a processor and is configured to insert at least one laminated core from an inlet of a feeding pipe onto a receiving mechanism. The laminated core comprises multiple electromagnetic steel sheets, and the feeding pipe sequentially includes a heating zone, a cooling zone, and a discharging port, with the heating zone and the cooling zone located between the inlet and the discharging port. The pressing unit is electrically connected to a processor and is configured to apply a pressure to an upper surface of the laminated core using a pressing mechanism, and apply an upper pressure to a lower surface of the laminated core using the receiving mechanism, so that the laminated core bears a pressure value. The moving unit is electrically connected to a processor. The processor is connected to the moving unit, which is configured to push down the laminated iron core using the pressing mechanism, causing the laminated iron core to move from the inlet of the feed pipe to the outlet of the feed pipe; the heating unit is electrically connected to the processor, which is configured to heat the laminated iron core using a heating module when the laminated iron core passes through a heating area of the feed pipe, causing the surface coating of the multiple electromagnetic steel sheets of the laminated iron core to become sticky and thermally solidify; the cooling unit is electrically connected to the processor, which is configured to cool the laminated iron core using a cooling module when the laminated iron core passes through a cooling area of the feed pipe; the discharge unit is electrically connected to the processor, which is configured to press the laminated iron core using the pressing mechanism, causing the laminated iron core to exit from the outlet of the feed pipe to form a finished product.
[0009] In one embodiment of this application, in the moving unit, the lower pressure is greater than the upper pressure, causing the laminated iron core to be pushed down in the feed pipe and move at a speed.
[0010] In one embodiment of this application, the laminated iron core moves downward in a vertical direction at a fixed speed in the feed pipe.
[0011] In one embodiment of this application, prior to the pressing unit, the system further includes a limiting unit electrically connected to the processor, and the limiting unit is configured to adjust the laminated iron core to a predetermined position using a clamping ring disposed at the inlet of the feed pipe.
[0012] In one embodiment of this application, after the moving unit, the system further includes a monitoring unit electrically connected to the processor, and the monitoring unit is configured to use a laser rangefinder to monitor a displacement change of the pressing mechanism in order to calculate a movement time of the laminated iron core through at least one region of the feed pipe.
[0013] In one embodiment of this application, in the cooling unit, the laminated iron core is first cooled by a water-cooled pipeline of the cooling module, and then cooled by an air-cooled pipeline of the cooling module.
[0014] In one embodiment of this application, the pressure value borne by the laminated core in the pressing unit is 0.1 MPa to 0.5 MPa.
[0015] To achieve the above objectives, this application provides an apparatus for manufacturing self-adhesive coated motor cores. The apparatus includes a process platform, a feed pipe, a receiving mechanism, a pressing mechanism, a heating module, and a cooling module. The feed pipe is disposed on the process platform and includes an inlet, a heating zone, a cooling zone, and an outlet. The inlet is configured to receive a laminated core. The receiving mechanism is disposed below the process platform and is configured to move into the feed pipe to receive the laminated core, applying an upward pressure to the lower surface of the laminated core. The pressing mechanism is disposed on the process platform. The pressing mechanism is configured to move into the feed pipe and apply pressure to an upper surface of the laminated iron core, causing the laminated iron core to bear a pressure value; the heating module is located outside the feed pipe and heats a heating area of the feed pipe; the cooling module is located outside the feed pipe and below the heating module, and cools a cooling area of the feed pipe; the pressing mechanism pushes down the laminated iron core, causing the laminated iron core to move from the feed port of the feed pipe to the discharge port of the feed pipe, and causing the laminated iron core to exit from the discharge port of the feed pipe to form a finished product.
[0016] In one embodiment of this application, the device includes a laser rangefinder disposed on one side of the pressing mechanism. The laser rangefinder is configured to monitor a displacement change of the pressing mechanism to calculate a travel time of the laminated iron core through at least one region of the feed pipe.
[0017] In one embodiment of this application, the device further includes a side pusher mechanism disposed on the process platform, and the side pusher mechanism is configured to push the finished product exiting the feed channel from the discharge port to a specific position.
[0018] As described above, the apparatus for manufacturing self-adhesive coated motor cores of this application, by placing the heating module and the cooling module outside the feed pipe and positioning the heating module above the cooling module, utilizes vertical continuous thermosetting to produce the laminated core. Since the base material is completely broken into the electromagnet sheets during punching and shearing, the electromagnet sheets are then stacked into laminated cores of a predetermined height and continuously fed into the feed pipe for vertical moving continuous thermosetting. This significantly reduces the time required for manual material placement and batch heating and curing, thereby improving work efficiency. This assists customers in implementing the mass production process after self-adhesive electromagnet sheets and is well-suited to meet the demand for self-adhesive cores with different shapes and small quantities.

Therefore, the directional terms used are for illustrative and understanding purposes only, and not for limiting the scope of this application.
[0026] Please refer to Figures 1, 2, and 3, which illustrate an apparatus for manufacturing a self-adhesive coated motor core according to an embodiment of this application. The apparatus includes a process platform 2, a feed pipe 3, a receiving mechanism 4, a pressing mechanism 5, a heating module 6, and a cooling module 7. The detailed structure, assembly relationship, and operating principle of each component will be described in detail below.
[0027] Referring again to Figures 1, 2 and 3, the process platform 2 is located at the end of a conveying unit 101. Multiple self-adhesive coated electromagnetic steel sheets 102 (Electrical steel, ES) are punched into a predetermined shape by a punching and shearing unit 103. Then, the electromagnetic steel sheets 102 are processed by a rapid collection unit 104, so that the electromagnetic steel sheets 102 are stacked to a predetermined number to form a stacked motor core 105. Then, the stacked motor core 105 is placed into the vertically continuous thermosetting feed pipe 3 by the conveying unit 101.
[0028] Referring to Figures 2, 3, and 4, the feed pipe 3 is disposed on the process platform 2. Specifically, the feed pipe 3 includes a feed inlet 31, a heating zone 32, a cooling zone 33, a discharge outlet 34, and a clamping ring 35. The feed inlet 31 is configured to allow the laminated iron core 105 to be inserted. The clamping ring 35 is disposed at the feed inlet 31 of the feed pipe 3, and the clamping ring 35 is configured to adjust the laminated iron core 105 to a predetermined position.
[0029] Referring to Figures 2, 3 and 4, the receiving mechanism 4 is disposed under the process platform 2. Specifically, the receiving mechanism 4 is configured to move into the feed pipe 3 to receive the laminated iron core 105 and apply an upper pressure L2 to the lower surface of the laminated iron core 105.
[0030] In this embodiment, the receiving mechanism 4 is a hydraulic cylinder located below the process platform 2. The receiving mechanism 4 is operated to extend into the feed pipe 3 and pushes the laminated iron core 105 with the upper pressure L2, so that the lower surface of the laminated iron core 105 bears the upper pressure L2.
[0031] Referring to Figures 2, 3 and 4, the pressing mechanism 5 is disposed on the process platform 2. The pressing mechanism 5 is configured to move into the feed pipe 3 and apply a pressure L1 to an upper surface of the laminated iron core 105, so that the laminated iron core 105 bears a pressure value.
[0032] In this embodiment, the pressing mechanism 5 includes an upper mold 51, an upper mold hydraulic cylinder 52, and an upper mold inlet 53. The upper mold 51 is connected to the inlet 31 of the feeding pipe 3. The upper mold hydraulic cylinder 52 is located above the process platform 2. The upper mold inlet 53 is configured to allow the laminated iron core 105 to move horizontally and be stored in the upper mold 51. The upper mold hydraulic cylinder 52 is configured to move through the upper mold 51 to the feeding pipe 3.
[0033] Specifically, after the laminated iron core 105 is inserted into the upper mold inlet 53, the upper mold hydraulic cylinder 52 of the pressing mechanism 5 is operated to move into the feed pipe 3, and pushes the laminated iron core 105 down with the downward pressure L1, so that the upper surface of the laminated iron core 105 bears the downward pressure L1. The laminated iron core 105 is simultaneously subjected to the upward pressure L2 of the receiving mechanism 4 and the downward pressure L1 of the pressing mechanism 5, thus bearing the pressure value. Because the downward pressure L1 is greater than the upward pressure L2, the laminated iron core 105 is pushed down in the feed pipe 3 and moves at a certain speed.
[0034] Referring again to Figures 2, 3, and 4, the heating module 6 is disposed outside the feed pipe 3 and heats the heating area 32 of the feed pipe 3. In this embodiment, the heating module 6 is a metal tube surrounding the feed pipe 3, which heats the metal tube through induction heating, such as through electromagnetic induction, thereby raising the temperature of the heating area 32 of the feed pipe 3.
[0035] Referring again to Figures 2, 3, and 4, the cooling module 7 is disposed outside the feed pipe 3 and below the heating module 6, and cools a cooling area of the feed pipe 3. In this embodiment, the cooling module 7 includes a water-cooled pipeline 71 and an air-cooled pipeline 72, which surround the feed pipe 3. The water-cooled pipeline 71 is disposed on the air-cooled pipeline 72. The water-cooled pipeline 71 is used to cool the laminated iron core 105, for example, to 270 to 150 degrees Celsius, and then the air-cooled pipeline 72 is used for further cooling, for example, to below 100 degrees Celsius.
[0036] Referring to Figures 2, 3 and 4, the device further includes a first laser rangefinder 80 and a second laser rangefinder 81. The first laser rangefinder 80 is disposed on one side of the receiving mechanism 4, and the second laser rangefinder 81 is disposed on one side of the pressing mechanism 5.
[0037] In this embodiment, the first laser rangefinder 80 is configured to monitor a displacement change of the receiving mechanism 4 to calculate the pressure relief parameter of the receiving mechanism 4, and the second laser rangefinder 81 is configured to monitor a displacement change of the upper mold hydraulic cylinder 52 of the lower pressing mechanism 5 to calculate a movement time of the laminated iron core 105 through at least one area of the feed pipe 3.
[0038] Referring to Figures 2, 3 and 5, the device further includes a side pushing mechanism 82, which is disposed on the process platform 2. In this embodiment, the side pushing mechanism 82 is configured to push a finished product exiting the discharge port 34 of the feed channel 3 to a specific position.
[0039] Referring to Figures 2 and 3, the device further includes a grating 83, which is disposed on the process platform 2 and located around the feed pipe 3. The grating 83 is configured to sense objects approaching the feed pipe 3 and issue a warning notification.
[0040] Referring to Figures 4 and 5, the device further includes a first infrared thermometer 84 and a second infrared thermometer 85. The first infrared thermometer 84 and the second infrared thermometer 85 are disposed around the feed pipe 3, and the first infrared thermometer 84 is located above the second infrared thermometer 85. The first infrared thermometer 84 is configured to detect the temperature of the heating area 32 of the feed pipe 3, and the second infrared thermometer 85 is configured to detect the temperature of the cooling area 33 of the feed pipe 3.
[0041] Based on the above structure, the upper mold hydraulic cylinder 52 of the pressing mechanism 5 pushes down the stacked iron core 105, causing the stacked iron core 105 to move from the inlet 31 of the feed pipe 3 to the outlet 34 of the feed pipe 3. During the movement, the stacked iron core 105 is heated by passing through the heating area 32, causing the surface coating of the multiple electromagnetic steel sheets 102 of the stacked iron core 105 to become sticky and thermally solidify. Then, the stacked iron core 105 is cooled to a predetermined temperature, such as below 70 degrees Celsius, by passing through the cooling area 33. Finally, the stacked iron core 105 is withdrawn from the outlet 34 of the feed pipe 3 to form a finished product.
[0042] As described above, the apparatus for manufacturing self-adhesive coated motor cores of this application, by placing the heating module 6 and the cooling module 7 outside the feed pipe 3 and positioning the heating module 6 above the cooling module 7, utilizes vertical continuous thermosetting to produce the laminated core 105. Since the base material is completely broken into the electromagnetic steel sheet 102 during punching and shearing, the electromagnetic steel sheet 102 can be stacked into a laminated core of a predetermined height and continuously fed into the feed pipe 3 for vertical continuous thermosetting. This significantly reduces the time required for manual material placement and batch heating and curing, assisting customers in implementing mass production processes after self-adhesive electromagnetic steel sheets. It is also well-suited for meeting the demand for self-adhesive cores with different shapes and small quantities.

The operating units and principles of each component will be described in detail below.
[0044] Referring again to Figure 1 and in conjunction with Figure 6, the punching unit 200 is electrically connected to a processor 100, and the punching unit 200 is configured to control a punching and shearing unit 103, such as a punch press, to punch a pre-punched steel strip to form a plurality of pre-punched electromagnetic steel sheets 102 on the pre-punched steel strip.
[0045] Referring again to Figure 1 and in conjunction with Figure 6, the conveying unit 201 is electrically connected to the processor 100. The conveying unit 201 is configured to control a rapid collection unit 104 to press the electromagnetic steel sheet 102 into a region, so that the electromagnetic steel sheet 102 reaches a predetermined quantity and is stacked into a laminated iron core 105. Then, the laminated iron core 105 is placed into the vertically continuous thermosetting feed pipe 3 by the conveying unit 101. In this embodiment, the laminated iron core 105 is formed by stacking multiple self-adhesive coated electromagnetic steel sheets.
[0046] Please refer to Figures 1, 2, and 3, and in conjunction with Figure 6. The feeding unit 202 is electrically connected to the processor 100. The feeding unit 202 is configured to control the stacked iron core 105 to be inserted from an inlet 31 of a feeding pipe 3 and placed on a receiving mechanism 4. The stacked iron core 105 includes a plurality of electromagnetic steel sheets 102. The feeding pipe 3 sequentially includes a heating zone 32, a cooling zone 33, and an outlet 34. The heating zone 32 and the cooling zone 33 are located between the inlet 31 and the outlet 34.
[0047] In this embodiment, the receiving mechanism 4 is first operated to extend into the feed pipe 3. After the stacked iron core 105 is stored in the upper mold inlet 53 of the pressing mechanism 5, the upper mold hydraulic cylinder 52 of the pressing mechanism 5 is operated to move into the feed pipe 3, and then the stacked iron core 105 is placed from the feed port 31 of the feed pipe 3.
[0048] Please refer to Figures 1, 2, and 3, and in conjunction with Figure 6, the limiting unit 203 is electrically connected to the processor 100. The limiting unit 203 is configured to adjust the laminated iron core 105 to a predetermined position using a tensioning ring 35 provided at the inlet 31 of the feed pipe 3.
[0049] In this embodiment, the clamping ring 35 is configured to allow the laminated iron core 105 to pass through. During the passage, a central axis of the laminated iron core 105 is adjusted to overlap with a central axis of the feed channel 3.
[0050] Referring to Figures 1, 2, and 3, and in conjunction with Figure 6, the pressing unit 204 is electrically connected to the processor 100. The pressing unit 204 is configured to apply a pressure L1 to an upper surface of the laminated core 105 using a pressing mechanism 5, and to apply an upper pressure L2 to a lower surface of the laminated core 105 using a receiving mechanism 4, causing the laminated core to bear a pressure value. In this embodiment, the pressure value borne by the laminated core 105 is 0.1 MPa to 0.5 MPa, and the equation for the pressure value is F1 = 1.05 × A × Ms, where F1 is the applied pressure, A is the area of the laminated core, and Ms is the coefficient of friction.

The moving unit 205 is configured to use the pressing mechanism 5 to push down the laminated iron core 105, causing the laminated iron core 105 to move from the inlet 31 of the feed pipe 3 to the outlet 34 of the feed pipe 3. In this embodiment, the downward pressure L1 exerted by the pressing mechanism 5 on the laminated iron core 105 is greater than the upward pressure L2 applied by the receiving mechanism 4 to the laminated iron core 105, causing the laminated iron core 105 to be pushed down in the feed pipe 3 and move at a certain speed. Specifically, the laminated iron core 105 moves downward in a vertical direction at a fixed speed in the feed pipe 3, and the equation for the speed is V = ft × h0, where ft is the speed, ft is the number of pieces moved per second, and h0 is the thickness of a single piece.
[0052] Referring to Figures 1, 2, and 3, and in conjunction with Figure 6, the monitoring unit 206 is electrically connected to the processor 100. The monitoring unit 206 is configured to use a first laser rangefinder 81 to monitor a displacement change in the pressing mechanism 5, in order to calculate a travel time of the laminated iron core 105 through at least one region of the feed pipe 3. For example, this could be the travel time of the laminated iron core 105 as it passes through the heating region 32 where it is heated, or the travel time of the laminated iron core 105 as it passes through the cooling region 33 where it is cooled.
[0053] Please refer to Figures 1, 2, and 3, and in conjunction with Figure 6. The heating unit 207 is electrically connected to the processor 100. The heating unit 207 is configured to heat the laminated iron core 105 using a heating module 6 when the laminated iron core 105 passes through the heating area 32 of the feed pipe 3, so that the surface coating of the multiple electromagnetic steel sheets 102 of the laminated iron core 105 becomes sticky and is thermally cured.
[0054] In this embodiment, the heating module 6 is a metal tube surrounding the feed pipe 3. The metal tube is heated by induction heating, such as by electromagnetic induction, thereby raising the temperature of the heating area of the feed pipe 3.
[0055] Please refer to Figures 1, 2, and 3, and in conjunction with Figure 6. The cooling unit 208 is electrically connected to the processor 100. The cooling unit 208 is configured to cool the laminated iron core 105 using a cooling module 7 when the laminated iron core 105 passes through the cooling area 33 of the feed pipe 3. Specifically, the laminated iron core 105 is first cooled by water cooling, and then cooled by air cooling.
[0056] In this embodiment, the cooling module 7 includes a water-cooled pipeline 71 and an air-cooled pipeline 72. The water-cooled pipeline 71 and the air-cooled pipeline 72 surround the feed pipe 3, and the water-cooled pipeline 71 is disposed on the air-cooled pipeline 72.

The discharge unit 209 is configured to use the pressing mechanism 5 to pressurize the laminated iron core 105, so that the laminated iron core 105 exits from the discharge port 34 of the feed pipe 3 to form a finished product.
[0058] In this embodiment, when the laminated iron core 105 is cooled to below 100 degrees Celsius by the cooling module 7 through the cooling area 33 of the feed pipe 3, the pressing mechanism 5 continuously applies a pushing pressure to the laminated iron core 105, causing the laminated iron core 105 to move downwards in the feed pipe 3 and then exit from the discharge port 34.
[0059] As described above, the system for manufacturing self-adhesive coated motor cores of this application, by placing the heating module 6 and the cooling module 7 outside the feed pipe 3 and positioning the heating module 6 above the cooling module 7, utilizes vertical continuous thermosetting to produce the laminated core 105 during the sequential heating unit 207 and cooling unit 208 processes. Since the base material is completely broken into the electromagnetic steel sheet 102 during punching and shearing, the electromagnetic steel sheet 102 can be stacked into a laminated core of a predetermined height and continuously fed into the feed pipe 3 for vertical continuous thermosetting. This significantly reduces the time required for manual material placement and batch heating and curing, assisting customers in implementing mass production processes after self-adhesive electromagnetic steel sheets. It is also well-suited for meeting the demand for self-adhesive cores with different shapes and small quantities.
