Description

Technical Field

[0001] This invention relates to the field of automatic assembly technology, and more specifically to a static iron core guide ring pressing device. Background Technology

[0002] As a key component in modern industrial equipment, the stability and reliability of CDC damping valves are of paramount importance. During the installation of a CDC damping valve, a guide ring needs to be press-fitted into the stationary iron core. The lower end face of the stationary iron core has a stepped hole, the top hole of which matches the guide ring for installation. The guide ring is made of copper and has a hexagonal structure, resembling a hexagonal nut. When pressing the guide ring into the stationary iron core, a portion of its hexagonal structure needs to be cut to fit the top hole of the stationary iron core; therefore, the guide ring cannot be directly inserted into the stepped hole of the stationary iron core for installation, and press-fitting is required to achieve an interference fit.

[0003] In existing technologies, the press-fitting of guide rings typically employs manual or simple mechanical pressing methods, which have several shortcomings. For example, it is difficult to ensure the concentricity of the guide ring and the stationary iron core during pressing, resulting in poor product consistency and insufficient stability. Press-fitting efficiency is low, relying on manual operation, resulting in high labor intensity and a high risk of errors. During the pressing process, copper shavings from the hexagonal structure of the guide ring can easily remain inside the stepped holes, affecting assembly quality and product performance. Overall, production efficiency is low and cannot meet the needs of large-scale production.

[0004] Therefore, there is an urgent need to design a static iron core guide ring pressing device with a high degree of automation, good pressing accuracy, and guaranteed product quality to solve the above problems.

[0005] It should be noted that the above description of the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of the present invention and facilitating understanding by those skilled in the art. It should not be assumed that the above technical solutions are known to those skilled in the art simply because they have been described in the background section of this invention. Summary of the Invention

[0006] To overcome the shortcomings of the prior art, the present invention aims to provide a static iron core guide ring pressing device.

[0007] To achieve the above and other related objectives, the technical solution provided by this invention is: a stationary iron core guide ring pressing device, comprising an indexing table unit, the indexing table unit including a rotatable indexing plate, the indexing plate having a ring of evenly distributed installation positions, each installation position having a position positioning seat, and the position positioning seat having a pressing table, the upper end face of the pressing table having a first guide post for positioning the stationary iron core fixedly fixedly, and the upper end face of the first guide post having a second guide post for positioning the guide ring fixedly fixedly; the guide ring is fitted into the first guide post, and the stationary iron core is fitted into the second guide post, the first guide post, the second guide post, and the pressing table being an integral structure. During the pressing process, the first guide post extends into the inner hole of the guide ring, providing radial support to prevent deformation of the guide ring under pressure and ensuring that the shape of its internal circular hole remains unchanged. A magnetic shielding ring is fitted onto the lower end of the first guide post. This magnetic shielding ring is used to eliminate the magnetic interference of the stationary iron core itself on the pressing process, ensuring accurate pressing position. The central axis of the first guide post and the central axis of the second guide post coincide, ensuring the concentricity of the guide ring and the stationary iron core after press-fitting. After press-fitting, the guide ring achieves an interference fit within the stationary iron core.

[0008] During press fitting, the guide ring is first fitted into the second guide post, and its inner hole is precisely positioned; the stationary iron core is then fitted into the first guide post, and its stepped hole is precisely positioned. Since the central axes of the first and second guide posts coincide and are fixed on the same press fitting platform, the concentricity of the guide ring and the stationary iron core is forcibly guaranteed before press fitting, and the press only needs to provide vertical downward pressure to complete high-quality press fitting.

[0009] This solution enables multi-station cyclic operation through an indexing plate, improving efficiency; the coincidence of the axes of the first and second guide columns ensures the concentricity of the guide ring and the stationary iron core during pressing; the magnetic isolation ring effectively eliminates the interference of the stationary iron core's magnetism on the pressing process, improving pressing stability.

[0010] Furthermore, an adjusting cylinder is fixed to the lower end face of the pressing table. This adjusting cylinder vertically penetrates the workstation positioning seat, and its lower end is fixed to an integrated support base. A linear bearing is also fitted onto the adjusting cylinder. The lower end (non-fixed end) of the linear bearing penetrates the workstation positioning seat and abuts against the support base. An adjusting shim is provided between the flange end of the linear bearing and the workstation positioning seat, and the adjusting shim is detachably connected to the flange end of the linear bearing. Different heights of the adjusting cylinder on the workstation positioning seat can be adjusted by replacing adjusting shims of different thicknesses, thereby adjusting the height of the pressing table to ensure precise docking with the pressing unit. This solution allows for adjustment of the pressing table height by replacing adjusting shims of different thicknesses, adapting to the pressing requirements of products of different specifications; the linear bearing ensures accuracy during movement.

[0011] Furthermore, a first spring is fitted onto the adjusting cylinder, and the first spring is located between the pressing table and the linear bearing. In this design, the spring buffer structure effectively absorbs most of the impact energy during the pressing process, protecting the structure from damage; at the same time, it avoids the loss of positioning accuracy caused by impact, extending the service life of the equipment.

[0012] Furthermore, the device also includes a pressing unit for pressing the stationary iron core to the guide ring. The pressing unit includes a pressing frame with a press mounted on it. The pressing frame has a recessed mating area on its side near the indexing plate. The press is positioned above the mating area, and a pressing support plate is located at the lower end of the mating area. One side of the indexing plate is located within the mating area, and any of the installation positions can be vertically connected to the press and the pressing support plate. The press is a servo press. In this solution, the servo press, combined with a precision guiding structure, achieves repeatable precision control of the pressing force and pressing depth, improving pressing accuracy and efficiency.

[0013] Furthermore, the device also includes a first feeding unit for feeding the guide ring, the first feeding unit being located on one side of the indexing table unit, the first feeding unit including a first feeding mechanism and a first feeding mechanism; The first feeding mechanism includes a vibratory feeder and a feeding carrier docking with the vibratory feeder. The feeding carrier includes a feeding base, a feeding docking plate fixed to one side of the feeding base, and a feeding transfer plate movably mounted on the feeding base. The feeding docking plate has a docking groove for docking with the vibratory feeder, and the feeding transfer plate has a receiving groove corresponding to the docking groove on the side near the feeding docking plate. A linear guide rail is provided on the feeding base, and the feeding transfer plate is movably connected to the feeding base via the linear guide rail. The feeding transfer plate moves back and forth via a linear cylinder, which is fixed to the feeding base. A baffle is provided at both ends of the linear guide rail, and a limiter is provided on the inner side of each baffle to limit the feeding transfer plate. A through-beam optical fiber is also provided on the baffle to detect whether the guide ring enters the receiving groove. The guide ring enters the receiving groove from the vibratory feeder and is then fed by the feeding transfer plate.

[0014] The first feeding mechanism includes a first feeding mounting frame, on which a first feeding mounting seat capable of horizontal reciprocating motion is provided, and on which a first feeding gripper capable of vertical up-and-down motion is provided. The first feeding mounting frame is provided with a horizontal linear guide rail, and the first feeding mounting seat reciprocates on the linear guide rail using a miniature cylinder (model SMC-CDM2B25-200Z-M9P). The first feeding mounting seat is provided with a vertical linear guide rail, and the first feeding gripper moves up and down on the linear guide rail using a linear cylinder. The first feeding gripper uses a gripper cylinder to open and close to pick up material. During material picking, the first feeding gripper extends into a guide ring, and after extending into the inner hole of the guide ring, it expands radially, gripping the guide ring by friction. Subsequently, the entire first feeding mechanism transfers the material to the indexing table unit for feeding.

[0015] In this solution, the vibratory feeder and the precision transfer mechanism work together to achieve automatic sorting and precise positioning of the guide rings, with a high and stable feeding cycle. The internally tightened material handling method completely avoids damage to the hexagonal structure of the guide rings. The first feeding unit realizes automatic feeding and loading of the guide rings, improving the feeding accuracy and efficiency.

[0016] Furthermore, the device also includes a second feeding unit for feeding stationary iron cores, the second feeding unit being located on one side of the indexing table unit; The second feeding unit includes a robotic arm and a second feeding mechanism. The second feeding mechanism includes a second feeding mounting frame, on which a docking line, a feeding line, and a discharging line are installed. The discharging line is located below the feeding line, and both the feeding line and the discharging line can dock with the docking line. A tray carrying stationary iron cores is fed from the docking line. The feeding line delivers a fully loaded tray to the docking line. The robotic arm directly removes the stationary iron cores from the tray on the docking line and delivers them to the corresponding installation position on the indexing plate. When all the stationary iron cores on the tray are removed, the empty tray is sent away through the discharging line, and the feeding cycle continues.

[0017] The docking production line is mounted on a movable frame, which is vertically movable on the second loading mounting frame. The second loading mounting frame is equipped with a vertical linear guide rail, and the movable frame is mounted on the linear guide rail and moves up and down through a driving component, thereby realizing the vertical docking of the docking production line with the loading and unloading production lines.

[0018] Both sides of the feeding line are equipped with horizontally reciprocating pallets, the movement direction of which is perpendicular to the flow direction of the feeding line. Below each pallet is a lifting platform connected to it via a linear track. Multiple layers of trays are stacked on the feeding line, each carrying a stationary iron core. The pallets extend inwards via a drive mechanism. Initially, both pallets extend inwards and rise, supporting the entire stack of trays (except the bottom layer). When feeding is needed, the pallets descend, allowing the bottom tray to fall onto the feeding line, and then retract outwards. The feeding line then removes the bottom tray. Afterwards, the pallets extend inwards and rise again, supporting the remaining trays, completing one feeding cycle. This process repeats continuously to achieve continuous feeding.

[0019] In this solution, the second feeding unit realizes automated feeding and loading of static iron cores, the multi-layer tray automatic supply system realizes continuous feeding of static iron cores, and the pallet and lifting platform work together to realize multi-layer tray management, ensuring stability during tray transfer, thereby improving material supply efficiency.

[0020] Furthermore, the device also includes a detection unit located on one side of the indexing table unit; the detection unit includes a detection mechanism and a transfer mechanism, the transfer mechanism being located on one side of the detection mechanism; The detection mechanism includes a detection frame on which a vertically arranged displacement sensor is mounted. A detection platform capable of fitting a stationary iron core is fixed to the upper end of the detection frame. A detection column is vertically inserted through the detection platform. The upper end of the detection column extends beyond the upper end of the detection platform, and the lower end extends beyond the lower end of the detection platform and penetrates the detection frame. The diameter of the upper end of the detection column corresponds to the diameter of the guide ring and abuts against the guide ring. The lower end of the detection column abuts against the displacement sensor.

[0021] After the guide ring is press-fitted into the stationary iron core, it is picked up by a transfer mechanism and transferred to the testing mechanism for inspection. During testing, the transfer mechanism places the press-fitted assembly (stationary iron core and guide ring) onto the outside of the testing table. Then, the transfer mechanism presses down on the assembly, forcing the inner end face of the guide ring downwards to press against the testing column. The downward movement of the testing column is precisely detected by a displacement sensor; this downward movement corresponds to the press-fitting depth of the guide ring within the stationary iron core. The control system determines whether the product is qualified based on this depth. In this solution, the testing unit uses a displacement sensor to detect the press-fitting depth, ensuring the guide ring is properly press-fitted and improving product quality.

[0022] Furthermore, the upper part of the detection platform and the detection column are both cylindrical rotating bodies with their central axes coinciding; an integrated limiting ring is fitted onto the detection column, and a second spring is disposed below the limiting ring. In this design, the limiting ring and the second spring ensure the detection column is reset, improving detection stability and accuracy.

[0023] Furthermore, the transfer mechanism includes a transfer mounting frame, on which a transfer mounting base capable of horizontal reciprocating motion is mounted, and on which a transfer gripper capable of vertical up-and-down motion is mounted. The transfer mounting frame is equipped with a horizontal linear guide rail, and the transfer mounting base reciprocates on the linear guide rail using a miniature cylinder (model SMC-CDM2B25-200Z-M9P). A vertical transfer linear cylinder is mounted on the transfer mounting base, and the transfer gripper is connected to the transfer linear cylinder to achieve up-and-down motion on the linear guide rail. The transfer gripper uses a gripper cylinder to open and close for material handling. During material handling, the transfer gripper opens to grip the product to be tested and then transfers it to the testing platform of the testing unit. The product is then tested by pressing down with the transfer linear cylinder. A sensor for identifying the product to be tested is provided on one side of the transfer gripper to assist in material handling. In this solution, the transfer mechanism achieves automatic product transfer and testing, improving testing efficiency.

[0024] Furthermore, the device also includes a feeding unit for unloading the stationary iron core assembly after press-fitting. The feeding unit is located on one side of the indexing table unit. The feeding unit includes a conveyor line and a feeding mechanism. The feeding mechanism includes a feeding mounting frame straddling the conveyor line. The feeding mounting frame is provided with a feeding mounting seat capable of horizontal reciprocating motion, and the feeding mounting seat is provided with a feeding gripper capable of vertical up-and-down motion.

[0025] The unloading mounting frame is equipped with horizontal linear guides, and the unloading mounting base reciprocates along these guides via a combination of servo motors and lead screw assemblies. A vertical linear guide is also provided on the unloading mounting base, and the unloading grippers move up and down along these guides via the same combination of servo motors and lead screw assemblies. The unloading grippers use gripper cylinders to open and close for material handling. During unloading, the grippers open to pick up the stationary iron core assembly and then retrieve it from the indexing table to the conveyor line for unloading. A sensor on one side of the grippers identifies the stationary iron core assembly to assist in material handling. This unloading unit automates unloading, improving overall production efficiency.

[0026] Furthermore, the device also includes a chip blowing unit, which is mounted on the unloading mechanism and located below the unloading gripper. The chip blowing unit includes a support frame fixed to the unloading mounting frame, and an air jet device is mounted on the support frame. The air jet device has a cover with an air outlet at its upper end. During chip blowing, the unloading gripper first grasps the pressed-fit stationary iron core assembly above the air outlet. The chip blowing unit blows out the copper chips generated during pressing, and then the unloading gripper sends them to the conveyor line. The chip blowing unit removes the copper chips generated during pressing, preventing residue from affecting product performance.

[0027] Furthermore, the device also includes a cleaning unit for cleaning the installation station. The cleaning unit is located on one side of the indexing table unit. The cleaning unit includes a cleaning mounting frame with a cleaning hood that can move vertically up and down. An air jet device is installed inside the cleaning hood. During cleaning, the cleaning hood moves downwards to cover the installation station that has rotated below it. After the air jet device blows away the copper shavings, the cleaning hood returns to its original position, completing the cleaning process. The cleaning unit regularly cleans the installation station to maintain a clean working environment and ensure the quality of the pressing process.

[0028] Due to the application of the above technical solution, the beneficial effects of this invention compared with the prior art are as follows: This invention achieves a high degree of parallelism in the production process through the multi-station design of the indexing table and the precise coordination of each functional unit; it adopts a concentric structure of the first and second guide columns, combined with the precise control of the servo press, to ensure the consistency of pressing quality; it integrates functions such as automatic detection and chip cleaning, forming a complete quality assurance system, and is significantly superior to traditional pressing equipment in terms of production efficiency, product quality and automation.

[0035] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0036] Example: See appendix Figure 1 and attached Figure 2 As shown, this embodiment provides a static iron core guide ring pressing device, including a frame, a control system, and an indexing table unit 1, a pressing unit 2, a first feeding unit 3, a second feeding unit 4, a detection unit 5, a discharging unit 6, a chip blowing unit 7, and a cleaning unit 8 mounted on the frame.

[0037] See appendix Figure 3 Appendix Figure 4 and attached Figure 5 As shown, the indexing table unit 1 includes an indexing plate 101, which is driven by a servo motor to achieve precise intermittent rotation. Six mounting stations 102 are evenly distributed along the circumference of the indexing plate 101, and each mounting station 102 is equipped with a station positioning seat 103. A pressing table 104 is mounted on the station positioning seat 103 via an adjustment mechanism. This adjustment mechanism includes a vertically arranged adjusting cylinder 108, the upper end of which is fixedly connected to the pressing table 104, and the lower end passing through the station positioning seat 103 and fixedly connected to the support base 109. A linear bearing 110 is fitted onto the adjusting cylinder 108, and the flange end of the linear bearing 110 is connected to the station positioning seat 103 via adjusting shims 111 of different thicknesses. The height of the pressing table 104 can be adjusted by replacing the adjusting shims 111. A first spring 112 for buffering is also fitted on the adjusting cylinder 108, and the first spring 112 is located between the pressing table 104 and the linear bearing 110. Both the station positioning seat 103 and the adjusting pad 111 can be locked using a handle of model PAZ01-M4-L10.

[0038] A first guide post 105 is fixed to the upper end face of the pressing table 104, and a second guide post 106 is fixed to the upper end face of the first guide post 105. The central axes of the two are coincident and concentricity is ensured by high-precision machining. A magnetic shielding ring 107 made of non-magnetic material is sleeved on the lower part of the first guide post 105. The diameter of the second guide post 106 is adapted to the inner hole of the guide ring 9, and the diameter of the first guide post 105 is adapted to the stepped hole of the stationary iron core 10.

[0039] See appendix Figure 6As shown, the pressing unit 2 is located on one side of the indexing table unit 1, and includes a pressing frame 201 on which a servo press 202 is mounted. The pressing frame 201 has an inwardly recessed mating area 203 on the side near the indexing plate 101, and a pressing support plate 204 is located below the mating area 203. When the indexing plate 101 rotates, any installation station 102 can accurately stop within the mating area 203, aligning the first guide post 105 and the second guide post 106 above the pressing table 104 with the press head of the servo press 202.

[0040] See appendix Figure 7 Appendix Figure 8 and attached Figure 9 As shown, the first feeding unit 3 is located on the other side of the indexing table unit 1, and includes a first feeding mechanism and a first loading mechanism. The first feeding mechanism includes a vibratory feeder 301 and a feeding carrier 302 docked thereto. The feeding carrier 302 includes a feeding base 3021, on which a feeding transfer plate 3023 is mounted via a linear guide rail and is driven to reciprocate by a linear cylinder. A feeding docking plate 3022 is fixed to one side of the feeding base 3021. The feeding docking plate 3022 has a docking groove 3024 that docks with the discharge port of the vibratory feeder 301, and the feeding transfer plate 3023 has a receiving groove 3025 corresponding to the docking groove 3024. The first loading mechanism includes a first loading mounting frame 303, on which a first loading mounting seat 304 is mounted via a horizontal linear guide rail and is driven to move horizontally by a mini cylinder. The first feeding mounting base 304 is equipped with a first feeding gripper 305 via a vertical linear guide rail, which is driven to move up and down by a linear cylinder. The first feeding gripper 305 uses a gripper cylinder, and its gripper can extend into the inner hole of the guide ring 9 and then expand radially, relying on friction to pick up the material. This internally tightened material picking method avoids clamping the external hexagonal structure and effectively prevents deformation and damage to the guide ring.

Each side of the loading assembly line 404 has a horizontally reciprocating pallet 407, and a lifting platform 408 is located below the pallet 407, connected by a linear track. The robot arm 401 is a four-axis servo robot arm with a dedicated gripper at its end. The loading assembly line 404 transports a tray carrying a stationary iron core 10. The pallets 407, controlled by the lifting platform 408, support the upper tray, and the lower tray descends to the docking assembly line 403. The moving frame 406 moves up and down, connecting the docking production line 403 with either the loading production line 404 or the unloading production line 405. The robotic arm 401 removes the stationary iron core 10 from the docking production line 403 and places it on the first guide post 105 of the indexing table unit. The empty tray is then transported away via the unloading production line 405. The second loading unit automates the loading of the stationary iron core 10.

[0042] See appendix Figure 13 Appendix Figure 14 Appendix Figure 15 and attached Figure 16 As shown, the detection unit 5 is located at the next station after the indexing table unit 1, and includes a detection mechanism and a transfer mechanism. The detection mechanism includes a detection frame 501, on which a high-precision displacement sensor 502 is mounted. A detection table 503 is fixed to the upper end of the detection frame 501, and a detection column 504 is vertically inserted through the detection table 503. The upper end of the detection column 504 extends out of the upper surface of the detection table 503, and the lower end contacts the probe of the displacement sensor 502. A limiting ring 505 is fitted on the detection column 504, and a second spring 506 is provided below the limiting ring 505. The transfer mechanism includes a transfer mounting frame 507, on which a transfer mounting seat 508 is mounted via a horizontal linear guide rail and is driven to move horizontally by a mini cylinder. A transfer gripper 509 is mounted on the transfer mounting seat 508 via a vertical linear guide rail and is driven to move up and down by a transfer linear cylinder. The transfer mechanism uses the transfer gripper 509 to remove the pressed product and move it to the inspection table 503. During inspection, the transfer gripper 509 presses down, the inspection column 504 presses against the guide ring 9, and the displacement sensor 502 detects the displacement height to determine whether the pressing is in place.

[0043] See appendix Figure 17 and attached Figure 18As shown, the unloading unit 6 is located at the end of the indexing table unit 1, and includes a conveyor line 601 and an unloading mechanism. The unloading mechanism includes an unloading mounting frame 602 spanning the conveyor line 601. An unloading mounting seat 603 is mounted on the unloading mounting frame 602 via a horizontal linear guide rail and is driven to move horizontally by a servo motor and a lead screw assembly. An unloading gripper 604 is mounted on the unloading mounting seat 603 via a vertical linear guide rail and is driven to move up and down by another set of servo motors and a lead screw assembly.

[0044] See appendix Figure 18 As shown, the chip blowing unit 7 is mounted on the unloading mounting frame 602, including a support frame 701. An air jet device is mounted on the support frame 701, and a cover 702 is provided on the air jet device. An air blowing port 703 is opened at the upper end of the cover 702.

[0045] The unloading gripper 604 takes away the qualified product, moves it to the air outlet 703 of the chip blowing unit 7, blows away the copper chips with the air jet device, and then places the product on the conveyor line 601.

[0046] See appendix Figure 19 As shown, the cleaning unit 8 is located at the cleaning station of the indexing table unit 1, and includes a cleaning mounting frame 801. A cleaning cover 802 is mounted on the cleaning mounting frame 801 via a vertical linear guide rail and is driven up and down by a cylinder. An air jet device is installed inside the cleaning cover 802. When the mounting station 102 rotates to a position below the cleaning unit 8, the cleaning cover 802 moves downward to cover the station, the air jet device blows air to clean copper shavings, and then the cleaning cover 802 returns to its original position.

[0047] Workflow: During operation, the indexing plate 101 rotates intermittently according to a preset rhythm, and each installation station 102 passes through each station in sequence to complete the following process flow: Loading Station: When the unloaded installation station 102 rotates from the initial station 1 to the guide ring 9 loading area (station 2), the vibratory feeder 301 of the first loading unit 3 sorts the guide rings 9 and feeds them into the feeding carrier 302. The feeding transfer plate 3023 moves to align the receiving groove 3025 with the docking groove 3024 to receive the guide rings 9, and then moves back to the picking position. The first loading gripper 305 moves horizontally to the picking position and then descends. The first loading gripper 305 extends into the inner hole of the guide ring 9 and opens it to pick up the material. Then it rises and moves horizontally above the indexing table unit 1 to fit the guide ring 9 into the second guide post 106. Then, the installation station 102 rotates to station 3. At this time, the robot arm 401 of the second loading unit 4 takes the stationary iron core 10 from the carrier plate of the docking line 403 and fits it into the first guide post 105.

[0048] Press-fitting station: The mounting station 102, carrying the guide ring 9 and the stationary iron core 10, rotates to the docking area 203 (station 4) of the press-fitting unit 2. The pressure head of the servo press 202 descends, pressing the stationary iron core 10 against the guide ring 9, causing the guide ring 9 to be pressed into the top hole of the stepped hole of the stationary iron core 10. During this process, a portion of the hexagonal structure on the outside of the guide ring 9 is cut off to achieve a tight fit, and the resulting copper shavings fall into the stepped hole. The press-fitting support plate 204 provides stable support for the press-fitting process.

[0049] Inspection Station: After pressing is completed, the installation station 102 rotates to inspection unit 5 (station number 5). The transfer gripper 509 removes the pressed product from the installation station 102, moves horizontally above the inspection table 503, and then descends to place the product onto the inspection table 503. As pressing continues, the inspection column 504 presses against the guide ring 9, and the displacement sensor 502 detects the displacement. The control system then determines whether the pressing depth is qualified.

[0050] Unloading Station: Qualified products are transferred to unloading unit 6 (station number 6) by the transfer mechanism. After the unloading gripper 604 takes the product, it is first moved above the air outlet 703 of the chip blowing unit 7. The jet device sprays high-pressure gas to blow away the copper chips in the stepped hole. Then, the product is placed on the conveyor line 601 for discharging.

[0051] Cleaning station: When the empty installation station 102 rotates to the bottom of the cleaning unit 8 (station 1), the cleaning cover 802 descends to cover the pressing table 104, and the jet device sprays high-pressure gas to remove residual copper shavings and keep the station clean.

[0052] Overall working principle: The indexing plate 101 rotates intermittently, and the installation station 102 sequentially passes through the first feeding unit 3 (feeding the guide ring 9), the second feeding unit 4 (feeding the stationary iron core 10), the pressing unit 2 (pressing), the detection unit 5 (detection), the unloading unit 6 (unloading), and the cleaning unit 8 (cleaning). The entire process is automated, highly efficient, and precise, ensuring product quality.
