Technical Field

[0001] This invention relates to the field of manufacturing nanocrystalline components for anti-interference filters in new energy electric vehicles, specifically to an automated production assembly line and process method for three-phase filters with nanocrystalline magnetic cores. Background Technology

[0002] In the manufacturing process of nanocrystalline magnetic core three-phase filters, the various components are assembled manually, resulting in low production efficiency, long processing time, and a high defect rate. There is currently no fully automated assembly line, highlighting the need for improvement. Therefore, this invention proposes an automated production assembly line and process method suitable for nanocrystalline magnetic core three-phase filters. Summary of the Invention

[0003] In view of the problems existing in the prior art, the present invention proposes a fully automated and highly efficient automated production and assembly line and process method for three-phase filters with nanocrystalline magnetic cores.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows: An automated production and assembly line for a three-phase filter with a nanocrystalline magnetic core includes a top cover feeding mechanism, a turntable mechanism, three O-ring assembly mechanisms (one, two, and three), a top cover conveying mechanism, a top cover bottom shell feeding mechanism, a cover-closing turntable mechanism, a bottom dispensing mechanism, a nanocrystalline assembly mechanism, a top dispensing mechanism, and a cover-closing mechanism. The top cover feeding mechanism is connected to the turntable mechanism, and the top cover moves onto the turntable mechanism via the top cover feeding mechanism. The O-ring assembly mechanisms (one, two, and three) and the top cover conveying mechanism are sequentially arranged along the rotation direction of the turntable mechanism. The turntable mechanism rotates, carrying the top cover, and sequentially selects three O-ring assembly mechanisms for O-ring assembly. The input end of the top cover bottom shell feeding mechanism is connected to the top cover conveying mechanism. The output end of the mechanism is connected to the bottom shell feeding mechanism, and the output end of the top cover feeding mechanism is connected to the input end of the closing turntable mechanism. The bottom dispensing mechanism, nanocrystal assembly mechanism, top dispensing mechanism, and closing mechanism are arranged sequentially along the rotation direction of the closing turntable mechanism. The top cover with the O-ring assembled is conveyed to the top cover bottom shell feeding mechanism through the top cover conveying mechanism. The top cover bottom shell feeding mechanism conveys the top cover and bottom shell to the closing turntable mechanism at the same time. The closing turntable mechanism rotates to the bottom dispensing mechanism for bottom dispensing. After dispensing, the closing turntable mechanism continues to rotate to the nanocrystal assembly mechanism for nanocrystal assembly. After assembly, the closing turntable mechanism continues to rotate to the top dispensing mechanism for top dispensing. After dispensing, the closing turntable mechanism continues to rotate to the closing mechanism for closing, thus completing the product assembly.

[0005] Furthermore, the upper cover feeding mechanism includes an upper cover feeding support base, on which a material placement tray is installed. The material placement tray has a feeding tray and a discharging tray.

An O-ring installation and fixing fixture is installed on the moving block of the assembly lifting cylinder. An O-ring enlargement fixture is provided on the O-ring installation and fixing fixture. The feeding support bracket is fixed with an O-ring movable support and an O-ring mounting support. The O-ring movable support is fixed with a telescopic guide rod, and the O-ring mounting support is fixed with an assembly telescopic support.

[0009] Furthermore, the cover conveying mechanism includes a cover conveyor belt, which is mounted on a fixed support frame one and a fixed support frame two, with the two ends of the cover conveyor belt being a placement end and a retrieval end, respectively.

[0010] Furthermore, the upper cover and bottom shell feeding mechanism includes an upper cover and bottom shell conveyor bracket, on which an upper cover and bottom shell conveyor belt is mounted. A movable robotic arm bracket is provided on one side of the upper cover and bottom shell conveyor bracket, on which an upper cover and bottom shell movable robotic arm is mounted. A lifting bracket is provided on one side of the movable robotic arm bracket, and an upper cover and bottom shell gripper is fixed on the lifting bracket. The placement end of the upper cover conveyor mechanism is close to the end of the upper cover and bottom shell conveyor belt. The lid-closing turntable mechanism includes a turntable mechanism and a placement fixture unit. Several placement fixture units are provided near the edge of the positioning turntable. Each placement fixture unit includes an upper cover placement fixture and a bottom shell placement fixture.

[0011] Furthermore, the structure of the top dispensing mechanism is the same as that of the bottom dispensing mechanism; The bottom dispensing mechanism includes a dispensing device bracket, a dispensing robotic arm on the dispensing device bracket, a dispensing valve on the dispensing robotic arm, a dispensing needle on the dispensing valve, a dispensing bucket fixed on the dispensing device bracket, and the dispensing valve and the dispensing bucket connected by a glue delivery pipeline. The nanocrystal assembly mechanism includes a magnetic core turntable support base, a magnetic core placement plate on the magnetic core turntable support base, a material picking area and a material placing area on the magnetic core placement plate, wherein both the material picking area and the material placing area have magnetic core positioning areas, and a magnetic core gripper on the magnetic core placement plate, the magnetic core gripper being mounted on the magnetic core moving robotic arm of the moving robotic arm device. A magnetic core positioning bracket is provided on one side of the magnetic core turntable support base. A magnetic core positioning fixture is installed on the magnetic core positioning bracket. The magnetic core positioning bracket is fixed to the upper edge of the top platform in the cover-closing turntable mechanism.

[0012] Furthermore, the lid closing mechanism includes a lid closing bracket, a pneumatic pipeline, a lid clamp, a lid lifting support, and a sliding bracket. The lid lifting support is fixed to the lid closing bracket, the lid clamp is mounted on the lid lifting support, and the pneumatic pipeline is mounted on the lid clamp. The sliding bracket is installed on the lower part of the surface of the upper cover lifting support column.

[0013] This invention also proposes a process method for an automated production assembly line of nanocrystalline magnetic core three-phase filters, comprising the following steps: Step 1: First, the upper cover placed on the material placement tray is picked up by the grippers and placed on the upper cover placement fixture one of the turntable mechanism; Step 2: The upper cover placement fixture 1 with the upper cover is rotated to the front of the corresponding upper cover clamping fixture by the positioning turntable. Then the upper cover clamping fixture moves toward the position of the upper cover placement fixture 1. After it moves into place, it moves downward to clamp the upper cover. Step 3: When the upper cover clamping fixture clamps the upper cover, place the O-ring into the vibrating screening plate. The vibrating screening plate moves the O-ring to the straight material channel through vibration. The vibrating screening plate screens the O-rings through the controller. The O-rings move through the straight material channel to the O-ring feeding fixture. At this time, the telescopic guide rod moves and descends above the O-ring feeding fixture via the O-ring moving support. Then, the feeding lifting cylinder rises to push the O-ring onto the telescopic guide rod. The telescopic guide rod then moves above the O-ring mounting and fixing fixture. The guide rod descends onto the O-ring mounting fixture and fixes the O-ring into the O-ring enlargement fixture. At this time, the O-ring is enlarged by the O-ring enlargement fixture. The assembly telescopic support moves above the O-ring mounting fixture through the O-ring mounting support. When the assembly telescopic support descends, the assembly lifting cylinder rises and pushes the O-ring onto the assembly telescopic support. The assembly telescopic support moves above the left support of the upper cover through the feeding support fixing frame. The assembly telescopic support descends and fixes the O-ring to the O-ring mounting position on the left support of the upper cover. O-ring assembly mechanism two installs the O-ring on the middle support of the upper cover; O-ring assembly mechanism three installs the O-ring on the right support of the upper cover. Step 4: After the O-ring assembly mechanism 3 installs the O-ring on the right support of the top cover, move the installed O-ring onto the top cover conveyor belt; Step 5: The laser-engraved base is moved to the end via the top cover and bottom shell conveyor belt. The top cover is placed manually onto the top cover conveyor belt of the top cover conveyor mechanism. At this time, the top cover and bottom shell grippers simultaneously grab the base and the top cover and place them onto the top cover placement fixture 2 and the bottom shell placement fixture. Step 6: When the bottom shell placement fixture moves to the bottom dispensing station, the dispensing valve and dispensing needle are fixed on the dispensing robot arm. The glue is delivered through the glue delivery pipeline to the dispensing valve and discharged through the dispensing needle. The glue is dispensed to the bottom shell according to the set dispensing route program. Step 7: First, place the magnetic core in the magnetic core positioning area within the material picking area. The magnetic core gripper picks up the magnetic core from the material picking area and places it above the bottom housing mounting fixture. At this time, the magnetic core positioning fixture places it on the base through the movement of the magnetic core positioning bracket, which facilitates the positioning and installation of the magnetic core. Step 8: After the assembly in Step 7 is completed, the cover turntable mechanism continues to rotate to the top glue dispensing mechanism to perform top glue dispensing. The top glue dispensing process is the same as the bottom glue dispensing process. Step 9: After the top adhesive is applied, the upper cover is moved to the closing mechanism station via the positioning turntable. The upper cover gripper moves on the bracket to the top of the upper cover and descends at the same time. At this time, the upper cover lifting column rises to lift the upper cover so that the upper cover gripper can grab it. The upper cover gripper grabs the upper cover and moves it to the bottom shell and places it on the tooling. The upper cover gripper descends to install the upper cover on the base to complete the product closing.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1) The device of the present invention is used to assemble a three-phase filter with a nanocrystalline magnetic core, realizing an automated assembly line and avoiding the problems of low production efficiency, long time consumption and high defect rate. 2) By assembling a nanocrystalline magnetic core three-phase filter using the device of the present invention, an automated production line can be made to run 24 hours a day without interruption, avoiding the time loss of manual operation (such as shift handover, fatigue rest, etc.) and greatly improving production capacity.

[0034] This invention also proposes a process method for an automated production assembly line of nanocrystalline magnetic core three-phase filters, comprising the following steps: Step 1: First, the upper cover placed on the material placement tray 1-1 is picked up by the gripper 1-6 and placed on the upper cover placement fixture 2-7 of the turntable mechanism 2; Step 2: The upper cover placement fixture 2-7 with the upper cover is rotated by the positioning turntable 2-1 to the front of the corresponding upper cover pressing fixture 2-8. Then the upper cover pressing fixture 2-8 moves toward the position of the upper cover placement fixture 2-7. After it moves into place, it moves downward to press the upper cover. Step 3: When the upper cover clamping fixture 2-8 clamps the upper cover, place the O-ring into the vibrating screening plate 3-2. The vibrating screening plate 3-2 moves the O-ring to the straight material channel 3-3 through vibration. The vibrating screening plate 3-2 screens the O-ring through the controller 3-4. The O-ring moves through the straight material channel 3-3 to the O-ring feeding fixture 3-10. At this time, the telescopic guide rod 3-8 moves and descends above the O-ring feeding fixture 3-10 through the O-ring moving support column 3-6. Then, the feeding lifting cylinder 3-13 rises and pushes the O-ring onto the telescopic guide rod 3-8. Finally, the telescopic guide rod 3-8 moves above the O-ring installation and fixing fixture 3-11. Telescopic guide rod 3-8 descends onto O-ring mounting fixture 3-11 and fixes the O-ring into O-ring enlargement fixture 3-12. At this time, the O-ring is enlarged by O-ring enlargement fixture 3-12. At this time, assembly telescopic support column 3-9 moves above O-ring mounting fixture 3-11 through O-ring mounting support column 3-7. When installation telescopic support column 3-9 descends, installation loading lifting cylinder 3-14 rises and pushes the O-ring onto assembly telescopic support column 3-9. Assembly telescopic support column 3-9 moves above the left support column of the upper cover through loading support column fixing bracket 3-5. Assembly telescopic support column 3-9 descends and lowers the O-ring to fix it at the O-ring installation position of the left support column of the upper cover. O-ring assembly mechanism two: 4. Install the O-ring on the middle support of the top cover; O-ring assembly mechanism three: 5. Install the O-ring on the right support of the top cover; Step 4: After the O-ring assembly mechanism 35 installs the O-ring on the right support of the upper cover, move the installed O-ring onto the upper cover conveyor belt 6-1; Step 5: The laser-engraved base is moved to the end via the upper cover and bottom shell conveyor belt 7-1. The upper cover is placed manually onto the upper cover conveyor belt 6-1 of the upper cover conveyor mechanism 6. At this time, the upper cover and bottom shell gripper 7-6 simultaneously grabs the base and the upper cover and places them onto the upper cover placement fixture 8-1 and the bottom shell placement fixture 8-2. Step 6: When the bottom shell placement fixture 8-2 moves to the bottom dispensing station, the dispensing robot arm 9-2 fixes the dispensing valve 9-4 and the dispensing needle 9-5. The glue reaches the dispensing valve 9-4 through the glue delivery pipeline 9-3 and is discharged through the dispensing needle 9-5. The glue dispensing operation is performed on the bottom shell according to the set dispensing route program. Step 7: First, place the magnetic core in the magnetic core positioning area 10-7 within the material picking area 10-2. The magnetic core gripper 10-6 picks up the magnetic core from the material picking area 10-2 and places it above the bottom housing positioning fixture 8-2. At this time, the magnetic core positioning fixture 10-9 places it on the base through the movement of the magnetic core positioning bracket 10-8, which facilitates the positioning and installation of the magnetic core. Step 8: After the assembly in Step 7 is completed, the cover-closing turntable mechanism 8 continues to rotate to the top glue dispensing mechanism 11 to perform top glue dispensing. The top glue dispensing process is the same as the bottom glue dispensing process. Step 9: After the top adhesive is applied, the upper cover is moved to the closing mechanism station via the positioning turntable 2-1. The upper cover gripper 12-3 moves above the upper cover on the bracket and descends simultaneously. At this time, the upper cover lifting support column 12-4 rises to lift the upper cover so that the upper cover gripper 12-3 can grab it. The upper cover gripper 12-3 grabs the upper cover and moves it to the bottom shell above the tooling 8-2. The upper cover gripper 12-3 descends to install the upper cover onto the base, completing the product closing.

8. A process method for an automated production assembly line of a nanocrystalline magnetic core three-phase filter as described in claim 7, characterized in that... Includes the following steps: Step 1: First, the upper cover placed on the material placement tray (1-1) is picked up by the gripper (1-6) and placed on the upper cover placement fixture (2-7) of the turntable mechanism (2); Step 2: The upper cover placement fixture 1 (2-7) with the upper cover is rotated to the front of the corresponding upper cover pressing fixture (2-8) via the positioning turntable (2-1). Then the upper cover pressing fixture (2-8) moves toward the position of the upper cover placement fixture 1 (2-7). After moving into place, it moves downward to press the upper cover. Step 3: When the upper cover clamping fixture (2-8) clamps the upper cover, place the O-ring into the vibrating screening plate (3-2). The vibrating screening plate (3-2) moves the O-ring to the straight material channel (3-3) through vibration. The vibrating screening plate (3-2) screens the O-ring through the controller (3-4). The O-ring moves to the O-ring feeding fixture (3-10) through the straight material channel (3-3). At this time, the telescopic guide rod (3-8) moves to and descends above the O-ring feeding fixture (3-10) through the O-ring moving support column (3-6). At this time, the feeding lifting cylinder (3-13) rises and pushes the O-ring onto the telescopic guide rod (3-8). Then the telescopic guide rod (3-8) moves to the O-ring installation and fixing fixture (3-11). Above, the telescopic guide rod (3-8) descends onto the O-ring mounting fixture (3-11) and fixes the O-ring into the O-ring enlargement fixture (3-12). At this time, the O-ring is enlarged by the O-ring enlargement fixture (3-12). At this time, the assembly telescopic support column (3-9) moves above the O-ring mounting fixture (3-11) through the O-ring mounting support column (3-7). When the assembly telescopic support column (3-9) descends, the assembly lifting cylinder (3-14) rises and pushes the O-ring onto the assembly telescopic support column (3-9). The assembly telescopic support column (3-9) moves above the left support column of the upper cover through the feeding support column fixing bracket (3-5). The assembly telescopic support column (3-9) descends and lowers the O-ring to fix it at the O-ring installation position of the left support column of the upper cover. O-ring assembly mechanism two (4) Install the O-ring on the middle support of the top cover; O-ring assembly mechanism three (5) Install the O-ring on the right support of the top cover; Step 4: After the O-ring assembly mechanism 3 (5) installs the O-ring on the right support of the cover, move the installed O-ring onto the cover conveyor belt (6-1); Step 5: The laser-engraved base is moved to the end via the top cover and bottom shell conveyor belt (7-1). The top cover is placed manually onto the top cover conveyor belt (6-1) of the top cover conveyor mechanism (6). At this time, the top cover and bottom shell grippers (7-6) simultaneously grab the base and the top cover and place them onto the top cover placement fixture (8-1) and the bottom shell placement fixture (8-2). Step 6: When the bottom shell placement fixture (8-2) moves to the bottom dispensing station, the dispensing robot arm (9-2) fixes the dispensing valve (9-4) and dispensing needle (9-5). The glue reaches the dispensing valve (9-4) through the glue delivery pipeline (9-3) and is discharged through the dispensing needle (9-5). The glue is dispensed to the bottom shell according to the set dispensing route program. Step 7: First, place the magnetic core in the magnetic core positioning area (10-7) within the material picking area (10-2). The magnetic core gripper (10-6) picks up the magnetic core from the material picking area (10-2) and places it above the bottom housing placement fixture (8-2). At this time, the magnetic core positioning fixture (10-9) places it on the base through the movement of the magnetic core positioning bracket (10-8), which facilitates the positioning and installation of the magnetic core. Step 8: After the assembly in step 7 is completed, the cover turntable mechanism (8) continues to rotate to the top glue dispensing mechanism (11) to perform top glue dispensing. The top glue dispensing process is the same as the bottom glue dispensing process. Step 9: After the top adhesive is applied, the cover is moved to the closing mechanism station via the positioning turntable (2-1). The cover gripper (12-3) moves above the cover on the bracket and descends simultaneously. At this time, the cover lifting support column (12-4) rises to lift the cover so that the cover gripper (12-3) can grab it. The cover gripper (12-3) grabs the cover and moves it above the base placement fixture (8-2). The cover gripper (12-3) descends to install the cover onto the base, completing the product closing.
