Description

Technical Field

[0001] This utility model relates to the technical field of motor core processing equipment, and in particular to a self-adhesive core production equipment. Background Technology

[0002] Against the backdrop of the rapid development of the new energy vehicle industry, electric vehicle technology is advancing by leaps and bounds. Batteries, motors, and electronic control systems, as the three core components of new energy vehicles, play a crucial role in the overall performance of the vehicle. Among them, the motor, as the heart of an electric vehicle, is similar to the engine in a traditional gasoline-powered car, directly determining the driving force of the electric vehicle.

[0003] In existing technologies, stator laminations (silicon steel sheets) need to be stacked to form a shaped iron core. Current processing methods include laser welding of side welds and stamping and gluing. However, gaps still exist between the laminations, which still increases the energy consumption of the engine during operation. A method can be adopted to stamp and glue the silicon steel sheets, then stack them, and heat them to fill the gaps between the silicon steel sheets with glue, thereby reducing the existence of gaps. Utility Model Content

[0004] The purpose of this utility model is to provide a self-adhesive iron core production equipment. Through the cooperation of a sheet sorting machine, a pressure measuring machine, a shaping section, a heating tunnel furnace, and a feeding section, it can realize the stacking, pressure measuring, sheet addition and subtraction, inspection, screw locking, heating, screw removal, and cover removal of silicon steel sheets. Overall, it realizes the automatic forming of iron core, improves the processing efficiency and quality of iron core, and has a relatively simple structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a self-adhesive iron core production equipment, including a feeding line, a sheet sorting machine, a pressure measuring machine, and a heating tunnel furnace, and also including a shaping section and a unloading section. The shaping section includes a laminating / reducing mechanism, a rotary detection mechanism, and a screw-locking mechanism arranged sequentially along the feeding line. The rotary detection mechanism detects the iron core processed by the laminating / reducing mechanism. The screw-locking mechanism locks the detected iron core with a cover placed on its upper surface. The screw-locking mechanism is connected to the inlet of the heating tunnel furnace via the feeding line. The unloading section includes a screw-removing mechanism, a lifting mechanism, and an unloading mechanism. The screw-removing mechanism and the lifting mechanism are arranged sequentially along the feeding line, and the screw-removing mechanism is connected to the outlet of the heating tunnel furnace. The lifting mechanism lifts the iron core and cover processed by the screw-removing mechanism. The unloading mechanism includes a first moving module and a first clamping fixture disposed at the output end of the first moving module. The two sides of the first moving module are respectively disposed above the rotary detection mechanism and the lifting mechanism. The first clamping fixture is driven to move the iron core and cover lifted by the lifting mechanism to the unloading line and to move the cover to the upper end of the iron core processed by the rotary detection mechanism.

The fourth clamping fixture is located at the output end of the third moving module, and the carrying fixture is located beside the third moving module to carry silicon steel sheets. When multiple iron cores are processed by the pressure measuring machine, the fourth clamping fixture is driven to transfer the silicon steel sheets on the iron core to the carrying fixture. When fewer iron cores are processed by the pressure measuring machine, the fourth clamping fixture is driven to transfer the silicon steel sheets on the carrying fixture to the iron core.

[0009] As a further optimization, the lamination mechanism also includes a pair of clamping components, which are close to each other to clamp the iron core to be laminationd, thereby maintaining the stability of the iron core during lamination.

[0010] As a further optimization, the rotary detection mechanism includes a lifting and rotating assembly and a camera. The lifting and rotating assembly is located below the feeding line, and the camera is located beside the lifting and rotating assembly.

[0022] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0023] like Figures 1 to 5 As shown, a self-adhesive iron core production equipment includes a feeding line, a sheet sorting machine 20, a pressure measuring machine 30, and a heating tunnel furnace 50. It also includes a shaping section 40 and a unloading section 60. The shaping section 40 includes a sheet-adding / reducing mechanism 41, a rotary detection mechanism 42, and a screw-locking mechanism 43 arranged sequentially along the feeding line. The rotary detection mechanism 42 inspects the iron cores processed by the sheet-adding / reducing mechanism 41. The screw-locking mechanism 43 locks the inspected iron cores, which have covers placed on their upper surfaces, onto the cores. The screw-locking mechanism 43 is connected to the inlet of the heating tunnel furnace 50 via the feeding line. The unloading section 60 includes a screw-removing mechanism 61, a lifting mechanism 62, and an unloading mechanism 63. The screw removal mechanism 61 and the lifting mechanism 62 are arranged sequentially along the feeding line, and the screw removal mechanism 61 is connected to the outlet of the heating tunnel furnace 50. The lifting mechanism 62 lifts the iron core and cover after being processed by the screw removal mechanism 61. The unloading mechanism 63 includes a first moving module 631 and a first clamping fixture 632 set at the output end of the first moving module 631. The two sides of the first moving module 631 are respectively set above the rotary detection mechanism 42 and the lifting mechanism 62. The first clamping fixture 632 is driven to move the iron core and cover lifted by the lifting mechanism 62 to the unloading line and to move the cover to the upper end of the iron core processed by the rotary detection mechanism 42.

[0024] In this utility model, combined with Figure 6As shown, after the silicon steel sheets are stamped and glued, multiple silicon steel sheets 1000 need to be stacked to form an iron core 100. The specific preparation method is as follows: multiple silicon steel sheets 1000 are stacked on the iron core fixture 101. When the stacking reaches the set requirements (height, etc. meet the requirements), the cover 102 is placed against the upper end of the stacked silicon steel sheets 1000. The screw 1031 of the screw 103 passes through the through hole on the cover 102 and is locked in the locking hole 1010 on the iron core fixture 101. That is, the stacked silicon steel sheets 1000 are clamped between the iron core fixture 101 and the cover 102. After heating in the tunnel furnace 50 for a set time, the iron core 100 can be prepared. To improve the automation and efficiency of feeding, the feeding of silicon steel sheets 1000 and / or iron cores 100 is accomplished through feeding lines. Specifically, the feeding lines include a receiving line 201 and a first feeding line 202 in the wafer sorting machine 20, a second feeding line 301 in the pressure measuring machine 30, a third feeding line 401 in the shaping section 40, and a fourth feeding line 601 in the unloading section 60. Since the heating tunnel furnace 50 itself has a feeding structure, the feeding structure of the heating tunnel furnace can be connected through the third feeding line 401 and the fourth feeding line 601 to realize the series connection of the entire feeding line.In applying this utility model, after being stamped and formed by the stamping equipment 70 and glued, the silicon steel sheets 1000 are fed into the wafer sorting machine 20 via the receiving line 201. In the wafer sorting machine 20, multiple silicon steel sheets 1000 are stacked on the core fixture 101 to form a core 100, which is then fed by the first feeding line 202 to the second feeding line 301 within the pressure measuring machine 30. In the pressure measuring machine 30, the stacked silicon steel sheets 1000 are pressurized and their height is measured. After the pressure measuring is completed, the core fixture 101 and the stacked silicon steel sheets 1000 are fed into the third feeding line 401 in the shaping section 40. When moving to the adding / reducing sheet mechanism 41, if the core 100 meets the requirements after the pressure measuring, it will not be blocked. The material will continue to be fed on the third feeding line 401. If the result of the pressure measurement does not meet the requirements, the material will stop moving after being stopped. The addition or subtraction mechanism 41 will add or subtract pieces according to the result of the pressure measurement until the requirements are met, and then continue feeding on the third feeding line 401. When it moves to the rotary detection mechanism 42, the iron core fixture 101 and the stacked silicon steel sheets 1000 are stopped and lifted and rotated. Visual inspection (such as line scan inspection) is used to check for misaligned pieces. After the inspection is completed, the first clamping fixture 632 is driven by the first moving module 631 to move horizontally above the stacked silicon steel sheets 1000, and after descending, it places the cover 102 it clamps on the top of the stacked silicon steel sheets 1000, and continues feeding on the third feeding line 401. The material is fed on the feeding line 401. When it moves to the screw-locking mechanism 43, it is blocked and lifted. The screw gun can lock the screw 103, so that the lower end of the screw 1031 is locked on the iron core tooling 101. It continues to be fed on the third feeding line 401 and is fed into the heating tunnel furnace 50 for heating. Under a certain pressure, the glue between the silicon steel sheets 1000 is solidified, ensuring that the gap between the silicon steel sheets 1000 is reduced and the adjacent silicon steel sheets 1000 are tightly abutted. The iron core 100 formed in this way can ensure the stability of the engine operation. After being heated at 280° for 4 hours and cooled for 2 hours, it flows out to the fourth feeding line 601 of the unloading mechanism 60. When it moves to the screw-removing mechanism 61, it is blocked. The material is lifted, the screw gun removes the screw 103, and continues to feed on the fourth feeding line 601. When it moves to the lifting mechanism 62, the iron core 100 and the cover 102 located at its upper end are lifted, the iron core fixture 101 is not lifted, and the first clamping fixture 632 can be driven to move the iron core 100 and cover 102 lifted by the lifting mechanism 62 to the unloading line 600 (during this process, the first clamping fixture 632 clamps the iron core 100). After the first clamping fixture 632 clamps the cover 102 to make it separate from the iron core 100, the iron core 100 can be unloaded through the unloading line 600. At the same time, the first clamping fixture 632 feeds the cover 102 to the upper end of the stacked silicon steel sheets 1000 processed by the rotary detection mechanism 42.

[0025] It should be noted that, in the preferred embodiment, the screw 103 can always be located on the cover 102. That is, when the cover 102 is placed on top of the stacked silicon steel sheets 1000, the screw 1031 of the screw 103 on the cover 102 extends into the locking hole 1010 of the iron core fixture 101 and is tightened by rotating with a screwdriver. When the screw is removed, only the lower end of the screw 1031 is unscrewed out of the locking hole 1010, while the screw 103 remains in the through hole of the cover 102 and is not removed. When the first clamping fixture 632 removes the cover 102, the screw 103 remains in the through hole on the cover 102 and is removed synchronously.

[0026] In this invention, multiple silicon steel sheets 1000 are stacked using a wafer sorting machine 20, a cover 102 is placed on the stacked silicon steel sheets 1000 using a feeding mechanism 63, the cover 102 is locked using a screw-locking mechanism 43 and clamped together with the iron core fixture 101 to hold the stacked silicon steel sheets 1000 in place, adhesive is applied using a heating tunnel furnace 50, and screws are removed using a screw-removing mechanism 61. Overall, the automatic forming of the iron core 100 is achieved, improving the processing efficiency and quality of the iron core 100. Moreover, the first moving module 631 in the feeding mechanism 63 completes the feeding of the iron core 100 and the transfer of the cover 102 through staged actions, which optimizes the overall structure.

[0027] The wafer handling machine 20 includes a loading mechanism 21, a feeding mechanism 22, and a turnover table 23, all of which are mounted on the first machine base 200. The turnover table 23 is located between the loading mechanism 21 and the feeding mechanism 22 and is used to position the iron core fixture 101. That is, the iron core fixture 101 is placed on the turnover table 23 manually or mechanically to support multiple silicon steel sheets 1000. The loading mechanism 21 includes a multi-axis robot 211 and a second clamping fixture 212 located at the output end of the multi-axis robot 211. The second clamping fixture 212 is driven to... Silicon steel sheets 1000 are clamped one by one on the receiving line 201 and stacked one by one on the iron core fixture 101 to form iron core 100. The feeding mechanism 22 includes a second moving module 221 and a third clamping fixture 222 disposed at the output end of the second moving module 221. The second moving module 221 can be a structure that can move in two-dimensional space, that is, it can move horizontally and vertically. The third clamping fixture 222 is driven to clamp the iron core fixture 101 carrying the iron core from the turnover table 23 and feed it to the first feeding line 202.

[0028] The first feeding line 202 located in the wafer sorting machine 20 is connected in series with the second feeding line 301 located in the pressure measuring machine 30. The iron core fixture 101 and the stacked silicon steel sheets 1000 fed by the first feeding line 202 are fed to the second feeding line 301 and enter the pressure measuring machine 30. The pressure measuring machine 30 includes a pressure bearing mechanism 31 and a pressure mechanism 32, both of which are set on the second machine base 300. The pressure bearing mechanism 31 has a lifting function, which can be used to lift the iron core fixture 101 carrying the iron core 100 located on the third feeding line 301 after it is raised. The pressure mechanism 32 (such as a 5T press) is located above the pressure bearing mechanism 31. It is used to press down on the iron core 100 and measure its height, which can realize the pressing between the stacked silicon steel sheets 1000. The pressure measuring machine 30 is an existing device. Its specific mechanism and working principle can be found in the "Automatic Pressure Measuring Device for Rotor Core of New Energy Vehicle Motor" with application number 202220549278.4.

[0029] After being pressurized and height-measured, the stacked silicon steel sheets 1000 are fed from the second feeding line 301 to the third feeding line 401 and enter the sheet-adding / reducing mechanism 41. The sheet-adding / reducing mechanism 41 is set on the third workbench 400 and includes a third moving module 411, a fourth clamping fixture 412, and a carrying fixture 413. The third moving module 411 can be a structure that moves in two-dimensional space, that is, it can move horizontally and vertically. The fourth clamping fixture 412 is set at the output end of the third moving module 411, and the carrying fixture 413 is set on the side of the third moving module 411 to carry the silicon steel sheets 1000. When multiple iron cores are processed by the pressurized and height-measured machine 30, the iron core fixture 101 and the stacked silicon steel sheets 1000 are fed on the third feeding line 401. When the core 100 is blocked, the fourth clamping fixture 412, driven by the third moving module 411, moves the excess silicon steel sheets 1000 on the core 100 to the bearing fixture 413. When the core is short of sheets after being processed by the pressure measuring machine 30, the core fixture 101 and the stacked silicon steel sheets 1000 fed on the third feeding line 401 are blocked. The fourth clamping fixture 412, driven by the third moving module 411, moves the silicon steel sheets 1000 on the bearing fixture 413 to the upper end of the core 100 to meet the design requirements. When the height of the core 100 processed by the pressure measuring machine 30 meets the requirements, the core fixture 101 and the stacked silicon steel sheets 1000 can be directly entered into the next process without being blocked at the addition / reduction mechanism 41 on the third feeding line 401.

[0030] Preferably, the addition / reduction mechanism 41 further includes a pair of clamping components 414, which can be a combination of cylinders and clamping plates. The pair of cylinders drive the pair of clamping plates to move closer to each other to clamp the iron core 100 that needs to be reduced. When the iron core 100 is clamped and fixed by the pair of clamping plates, the fourth clamping fixture 412 can still ensure the stability of the iron core 100 when performing the reduction action.

[0031] The rotary inspection mechanism 42 includes a lifting and rotating assembly 421 and a camera 422. The lifting and rotating assembly 421 is located below the third feeding line 401 and can be a combination of a lifting cylinder and a rotating table. The camera 422 is located beside the lifting and rotating assembly 421. When the iron core fixture 101 and the stacked silicon steel sheets 1000 fed on the third feeding line 401 move to the top of the lifting and rotating assembly 421, they are first blocked, then lifted and rotated by the lifting and rotating assembly 421, allowing the camera 422 to inspect the rotating iron core 100 for misalignment. After inspection, the lifting and rotating assembly 421 resets, and the iron core fixture 101 falls back onto the third feeding line 401 to continue feeding. For the qualified iron core 100, a cover 102 is placed on its upper end by the first clamping fixture 632 for locking in subsequent processes.

[0032] Furthermore, for iron cores that fail the inspection by the rotary inspection mechanism 42, the feeding line also includes an NG iron core unloading line 402 located next to the third feeding line 401. When an iron core fails the inspection, it is not processed by the screw-locking mechanism 43 in the third feeding line 401, but is directly fed to the side of the NG iron core unloading line 402. The unqualified iron core, together with the iron core tooling 101, is pushed onto the NG iron core unloading line 402.

[0033] Preferably, the unloading section 60 further includes a marking and scanning mechanism 64 for marking and scanning the iron core 100. When the iron core 100 is fed to the unloading line 600 by the first clamping fixture 632 and the cover 102 is removed by the first clamping fixture 632, the marking and scanning mechanism 64 marks and scans the iron core 100. It should be noted that the unloading line 600 can be a combination of a roller feeder and a belt feeder. The roller feeder is located at the beginning. When the iron core 100 is placed on it, initially the roller feeder does not operate (i.e., it does not feed), so that the first clamping fixture 632 can clamp the cover 102, and the marking and scanning mechanism 64 can mark and scan the iron core 100. After these actions are completed, the roller feeder operates to feed the iron core 100 onto the belt feeder.

[0034] The feeding line also includes a core tooling return line 602 located at the end of the fourth feeding line 601 and extending into the wafer sorting machine 20. After the core 100, after being processed by the screw removal mechanism 61, is fed on the fourth feeding line 601 and blocked, the lifting mechanism 62 lifts the core 100 and the cover 102. After the first clamping fixture 62 removes the core 100 and the cover 102, the blocking mechanism resets. The core tooling 101 remains on the fourth feeding line 601 and continues to be fed on the fourth feeding line 601 until it is fed to the core tooling return line 602. The core tooling return line 602 then feeds the core into the wafer sorting machine 20, so that the core tooling 101 can be placed on the turnover table 23 manually or mechanically.

[0035] Additionally, it should be noted that when the screw-locking mechanism 43 performs the screw-locking action, the iron core fixture 101 and the stacked silicon steel sheets 1000 are lifted (by a lifting structure such as a hydraulic cylinder) and then abut against the limiting plate 431. Through the upward lifting and the cooperation of the top limiting, the stacked silicon steel sheets 1000 can be pressurized to 3T. When the screw gun locks the screw, the pressure drops to 1.2T, and the locking is completed, ensuring that the stacked silicon steel sheets 1000 are tightly abutted against each other. Furthermore, the cover 102 is in the form of an upper plate + spring + lower plate. When the cover 102 is locked onto the iron core fixture 101 by the screw 103 and abuts against the upper end of the stacked silicon steel sheets 1000, the spring can provide continuous downward pressure to ensure that the multiple stacked silicon steel sheets are tightly abutted against each other.

[0036] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
