Description

Technical Field

[0001] The present invention belongs to the field of hollow cup production equipment, and more specifically, relates to an automatic production line for hollow cup molding. Background Art

[0002] The coreless motor uses a coreless cup as its rotor, eliminating the power loss caused by eddy currents formed in the iron core. At the same time, its weight and moment of inertia are greatly reduced, reducing the mechanical energy loss of the rotor itself. The energy density of the motor using the coreless cup is greatly improved. Compared with the motor with the same power and iron core, its weight and volume are greatly reduced. It is a highly efficient energy conversion mechanism.

[0003] Hollow cup motors are widely used in military, aerospace, civil appliances, industrial products and other fields due to their outstanding features such as high energy conversion efficiency, rapid starting and braking, stable and reliable operation, and small speed fluctuation.

[0004] Due to the sophisticated design of coreless motors, which require numerous components, the coreless motor, in particular, requires very high precision. Diamond-shaped coils, the basic unit of the coreless motor, are stacked and bonded together through hot pressing to form a coil block. The coil block is then rounded to form a cup-shaped coil block. The coil block then undergoes a series of processing steps, including cold pressing, rounding, rounding, and tinning, to create the final coreless motor.

[0005] Since the hollow cup motor has a precise design and many parts, especially the block wire cup, which requires very high precision, manual assembly is not only complicated, but also cannot guarantee its roundness and has low production efficiency. Summary of the Invention

The rotation of the first round rod 4011, the first rotating shaft 4032, and the first push rod 4031 does not affect the normal operation of the heating component.

[0089] Furthermore, one of the retrieving manipulators (the third manipulator) of the retrieving module includes a manipulator arm, a lifting drive mechanism B4022, a bracket, a pneumatic clamp, a compression spring and a second guide column 4021. The manipulator arm is mounted on the first base 407 through the manipulator running track 408. The lifting drive mechanism B4022 is mounted on the manipulator arm, and the bracket is mounted on the output shaft of the lifting drive mechanism B4022 to drive the bracket to move up and down. The pneumatic clamp is mounted on the bracket, and the pneumatic clamp includes The cylinder body and two clamping fingers 4020 driven by the cylinder body are used to clamp the segmented wire cup 7027. The second guide post 4021 is vertically arranged and located between the two clamping fingers 4020. The second guide post 4021 is slidably mounted on the support so as to adjust its position up and down to allow the segmented wire cup 7027 to be placed on or removed from the second guide post 4021. The upper end of the compression spring is connected to the support and the lower end is connected to the second guide post 4021. The compression spring can act as a buffer and allow the second guide post 4021 to have a certain amount of upward travel, thereby facilitating the second guide post 4021 to be withdrawn from the segmented wire cup 7027.

[0090] Furthermore, a connecting seat 4040 is fixedly mounted on the output shaft of the first lifting drive mechanism A4049. The lower end of the first push rod 4031 is provided with an annular bayonet. The connecting seat 4040 is provided with a slot that snaps into the annular bayonet of the first push rod 4031 to achieve a rotatable connection between the first push rod 4031 and the output shaft of the first lifting drive mechanism A4049. A plane bearing 4039 is installed on the first push rod 4031. The plane bearing 4039 is located above the annular bayonet. The plane bearing 4039 includes a lower cover, a rolling element, and an upper cover. The rolling element is located between the upper and lower covers. The lower cover is pressed against the connecting seat 4040. The upper cover and the first push rod 4031 have an interference fit, while the lower cover and the first push rod 4031 have a clearance fit. The lifting drive mechanism B4022 adopts a cylinder, which is equipped with a push-pull rod 4046. A push-pull plate 4048 is installed on the top of the push-pull rod 4046. A connecting seat 4040 is installed at the front end of the push-pull plate 4048. The connecting seat 4040 can be clamped on the annular bayonet at the bottom of the first push rod 4031. It is driven by the first lifting drive mechanism A4049 to push the push-pull rod 4046 to move up and down, thereby driving the push-pull plate 4048 to move up and down. When the push-pull plate 4048 moves upward, it pushes the plane bearing 4039 installed on the first push rod 4031. The plane bearing 4039 causes the first push rod 4031 to move upward, thereby pushing the first round rod 4011 installed on the first push rod 4031 to move upward. When the push-pull rod 4046 moves downward, it drives the push-pull plate 4048 to move downward, and pulls the first push rod 4031 downward through the connecting seat 4040, thereby pulling the first round rod 4011 downward.

[0091] Furthermore, the rounding module 50 is installed on the first base 407. The structure of the rounding module 50 is basically the same as that of the rounding module 40. The rounding module 50 includes a second molding tool and a plurality of second rounding components arranged around the first molding tool. The second molding tool has the same structure as the first molding tool. Each of the second rounding components includes a second pressing block 4018 driving mechanism 4013 and a second pressing block 4018 installed on the second pressing block 4018 driving mechanism 4013, and the second pressing block 4018 is provided with an arc surface equal to the outer diameter of the block wire cup 7027.

[0092] For the rounding module 40 of the present invention, its first round pressing components are preferably provided with six, the first pressing block 401 driving mechanism adopts a cylinder, and six first pressing block 401 driving mechanisms and first fixed seats 405 are evenly arranged around the first fixed column 4010, each first fixed seat 405 is provided with a first pressing block 401, and a first pushing rod 404 is provided between the output shaft of the first pressing block 401 driving mechanism and the pressing block, and two heating tubes B402 are installed on each first pressing block 401, and the lower part of the first base 407 is used to drive the first The driving component for the rotation and lifting of the round rod 4011 has a first through hole inside the first fixed column 4010 and a first boss 4026 in the middle. A first mounting hole 4027 is provided on the first boss 4026. The first fixed column 4010 is fixedly installed in the first through hole of the first base 407 by installing a pin or a screw 4025. The upper half of the first boss 4026 of the first fixed column 4010 is above the top surface of the first base 407, and the part below the boss 4026 is arranged below the top surface of the first base 407. A first gear box 4042 is installed at the front end of the first drive motor 4041. The first gear box 4042 is installed on a flange, and the flange is installed under the mounting platform 4038. Four mounting columns 4037 are arranged around the mounting platform 4038. The mounting platform 4038 is fixedly connected to the mounting columns 4037. The mounting columns 4037 are arranged under the first base 407, and the mounting columns 4037 are fixedly connected to the bottom of the first base 407. The first drive motor 4041 is connected to the input shaft of the first gear box 4042, and the output shaft of the first gear box 4042 is installed with the first driving gear 4047. The first driving gear 4047 and the first driven gear 4036 are engaged with each other. The first driven gear 4036 is installed on the first rotating shaft 4032. The upper end of the first push rod 4031 passes through the top of the first rotating shaft 4032 and the boss 4026 of the first fixed column 4010 to reach the top of the first base 407. The top of the first push rod 4031 is linked to the lower end of the first round rod 4011 through a bearing. The outside of the first round rod 4011 is provided with a first positioning sleeve 4024, and the first positioning sleeve 4024 is fixedly installed above the first fixed column 4010 by a screw 4025. The first positioning sleeve 4024 is hollow inside. After the first round rod 4011 rises, the upper end of the first round rod 4011 can extend from the top of the first positioning sleeve 4024. The interior of the first round rod 4011 is a hollow structure, and a heating pipe sleeve A4029 is installed. The heating pipe A4028 is installed inside the heating pipe sleeve A4029. A flange is provided at the bottom of the heating pipe sleeve A4029, and the flange part is placed above the bearing B4033 to prevent the heating pipe sleeve A4029 from falling.The first fixed column 4010, first positioning sleeve 4024, first round rod 4011, first push rod 4031, bearing, heating tube sleeve A4029, heating tube A4028, mounting platform 4038, first rotating shaft 4032, first driven gear 4036, first sensor plate 4035, first rotating shaft 4032, and locking nut are all coaxially mounted. Furthermore, the output shaft of the first drive motor 4041 is connected to a first encoder 4043; the first sensor plate 4035 is mounted on the first rotating shaft 4032, and a photoelectric sensor A4044 for detecting the first sensor plate 4035 is mounted on the first base 407. The photoelectric sensor A4044 is mounted on a photoelectric sensor mounting plate 4045, which is fixedly mounted on the mounting platform 4038. The first encoder 4043 on the first drive motor 4041 cooperates with the photoelectric sensor A4044 to detect the rotational position of the first rotating shaft 4032.

[0093] The circular calibration module 50 of the present invention also has multiple second pressure blocks 4018 evenly distributed on the periphery of the second round rod 4017. The second pressure blocks 4018 are arranged on the second fixed seat 4019. The second pressure block 4018 driving mechanism 4013 is arranged behind the second fixed seat 4019. The second pressure block 4018 driving mechanism 4013 adopts a booster cylinder. The second pressure block 4018 is also provided with a heating tube B402. The heating tube B402 generates heat, so that the second pressure block 4018 allows the block wire cup 7027 to deform due to heat around the second round rod 4017. A driving component is also provided under the second round rod 4017, which can drive the second round rod 4017 to rotate and move up and down. A temperature controller 4012 is mounted on the first base 407. Ten displays are included on the temperature controller 4012, showing the real-time temperatures of the six first pressing blocks 401 of the rounding module 40, the three second pressing blocks 4018 of the rounding module 50, and the first round rod 4011 of the rounding module 40. This allows for temperature control based on the different materials of the wire cups 7027, ensuring they remain within a stable temperature range. A compression spring on the second guide post 4021 pushes it upward when it strikes the second round rod 4017. This prevents deformation of the wire cups 7027 caused by the pneumatic gripper during the transition from rounding to rounding. A wire twisting module is located adjacent to the pneumatic gripper. The twisting module, pneumatic gripper, and second guide post 4021 are mounted on the same robotic arm, which operates on the robotic arm track 408 and transports the wire cups 7027 from the rounding module 40 to the rounding module 50. The robot arm running track 408 is driven and controlled by the robot arm motor 4014. The wire twisting module includes a wire twisting motor 4023 and a wire twisting chuck 4016. The wire twisting chuck 4016 is driven to rotate by the wire twisting motor 4023, and the robot arm motor 4014 controls the up and down movement of the robot arm. The drive motor, wire twisting motor 4023 and robot arm motor 4014 are all equipped with gear boxes and encoders, which can realize closed-loop control.

[0094] The working process of rounding and calibrating is as follows:

[0095] After the present invention is powered on, the robot clamps the wire cake and places it into the alcohol soaking device 406 to soften the surface of the enameled wire of the wire cake. The robot clamps the wire cake soaked in alcohol and places it into the first positioning sleeve 4024 of the rounding module 40, so that the wire cake is placed close to the first round rod 4011 of the rounding module 40. Depending on the position of the wire cake, the first pressing block 401 has different movement steps. According to the setting, the first pressing block 401 driving mechanism pushes the first pressing block 401 through the pushing rod, so that the first pressing block 401 moves forward on the movement track of the first fixed seat 405. Two heating tubes B402 are provided on the first pressing block 401. The heating tubes B402 generate heat to make the first pressing block 401 heat up, thereby making the wire cake softened by heat. After the set sequence, these first pressing blocks 401 repeat the above steps to deform the wire cake around the first round rod 4011 and connect end to end. At the same time, a heating tube A4028 and a heating tube sleeve A4029 are also provided inside the first round rod 4011, so that the wire cake is heated both inside and outside during the process of becoming the wire cup 7027. This not only makes the wire cake easier to heat and soften, but also ensures that the temperature difference between the inside and outside of the wire cup 7027 is not too large to affect the quality of the wire cup 7027.

[0096] After the spool cake is formed into a spool cup 7027, the first drive motor 4041, mounted below the first base 407, rotates, driving the first driving gear 4047 mounted at the front end of the gearbox. This in turn drives the first driven gear 4036, which meshes with the first driving gear 4047, to rotate. The rotation of the first driven gear 4036 drives the first rotating shaft 4032, the first sensing plate 4035, the first push rod 4031, and the first round rod 4011. The photoelectric sensor A4044 measures the real-time position of the first round rod 4011 and the set angle of rotation of the first round rod 4011. This eliminates the uneven heating of the spool cup 7027 caused by the gaps between the first pressing blocks 401, thereby improving the quality of the spool cup 7027. A first encoder 4043 is mounted at the rear end of the first drive motor 4041, enabling closed-loop control and more precise control.

[0097] After the block wire cup 7027 is rounded, the motor drives the pneumatic clamp and the second guide column 4021 on the robotic arm to move downward together. After reaching the set position, the wire twisting motor 4023 drives the wire twisting chuck 4016 to rotate. After the block wire cake is formed into the block wire cup 7027, the two enameled wires at the head and tail ends are twisted together to become one strand. After the twisting is completed, the wire cutting module 48 cuts off the excess wire ends 137-1 according to the settings. Furthermore, the pneumatic gripper and the second guide column 4021 on the robotic arm move downwardly driven by the motor. When the second guide column 4021 contacts the first round rod 4011 of the rounding module 40, the sensor detects the contact, and the controller controls the second lifting drive mechanism B4022 installed at the lower end of the first base 407 to pull the push-pull rod 4046, so that the connecting seat 4040 at the front end of the push-pull plate 4048 moves downward, thereby driving the first push rod 4031 to move downward. The downward movement of the first push rod 4031 drives the first round rod 4011 connected to the first push rod 4031 through the outer ring of the bearing B4033 to move downward, thereby driving the heating tube sleeve A4029 and the heating tube A4028 to move downward. During the downward movement of the first round rod 4011, the second guide column 4021 moves downward at the same time, so that the splice wire cup 7027 is smoothly inserted from the outside of the first round rod 4011 to the outside of the second guide column 4021. The first round rod 4011 descends to a position flush with the first positioning sleeve 4024, and the pneumatic gripper grips the segmented spool cup 7027. Simultaneously, the robotic arm moves upward a certain distance. Then, driven by the robotic arm motor 4014, the robotic arm moves to the right along the running track. After the pneumatic gripper removes the segmented spool cup 7027, the second lifting drive mechanism B4022 pushes the push-pull rod 4046, which in turn pushes the push-pull plate 4048 upward, causing the first push rod 4031 to move upward. This, in turn, drives the first round rod 4011, which is fixed to the first push rod 4031, upward, returning it to its previous position.

[0098] After the pneumatic gripper grasps the spool cup 7027, the second guide post 4021 remains positioned in the center of the spool cup 7027 as an internal support during movement, protecting the spool cup 7027 from deformation caused by the pneumatic gripper. When the pneumatic gripper reaches the designated position, the top of the second round bar 4017 of the calibration module 50 contacts the bottom of the second guide post 4021. The pneumatic gripper continues downward, and the compression spring on the second guide post 4021 compresses due to the obstruction of the second round bar 4017 of the calibration module 50, causing the spool cup 7027 to transition from the second guide post 4021 to the second round bar 4017 of the calibration module 50. The robotic arm then moves upward, repeating the previous command.

[0099] After the wire cup 7027 is positioned on the second round rod 4017 of the rounding module 50, the three second pressing blocks 4018 reciprocate on the second fixing seat 4019 according to the set instructions, aligning the wire cup 7027. The second forming fixture of the rounding module 50 is identical to the first forming fixture of the rounding module 40, except that the heating tube A4028 and heating tube sleeve A4029 are not installed. The movement is also the same.

[0100] Furthermore, the cooling module 60 includes a conveyor belt device, a spool protective cover 64, a block spool cup 7027 clamping device, a fan 65 and a spool protective cover 64 reflux conveying mechanism, wherein the spool protective cover 64 is used to be sleeved on the outside of the block spool cup 7027, the conveyor belt device is used to convey the block spool cup 7027, the fan 65 is used to air-cool the block spool cup 7027 on the conveyor belt device, and the block spool cup 7027 clamping device is used to clamp the block spool cup 7027 after air cooling, so that the material taking module takes away the spool protective cover 64 and places the spool protective cover 64 on the spool protective cover 64 reflux conveying mechanism to reflux to the set position.

[0101] Furthermore, the tin immersion device includes a frame, a tin immersion drive motor 702, a screw mechanism, a transverse cylinder 7012, a second base, a lifting cylinder 7021, a mounting base, an induction pen 7016, a rotating cylinder 7015 and a pneumatic finger 75. The tin immersion drive motor 702 and the screw mechanism are both installed on the frame. The output shaft of the tin immersion drive motor 702 is connected to the second encoder 701, and the output shaft of the tin immersion drive motor 702 is connected to the screw 707 of the screw mechanism to drive the screw 707 to rotate. The screw 707 is vertically arranged, and the inner teeth of the transmission nut are engaged with the outer teeth of the screw 707 to convert the spiral motion of the screw 707 into the linear motion of the transmission nut. The transmission nut of the screw mechanism can move up and down to achieve lifting and lowering. The tin immersion drive motor 702 can accurately control the lifting amount of the transmission nut through the measurement of the second encoder 701. The frame includes a second base 7011, a fixed platform 709 and a sliding platform 704, wherein the fixed platform 709 is mounted on the second base 7011, the sliding platform 704 is mounted on the fixed platform 709, and the lead screw 707 of the lead screw mechanism is mounted on the sliding platform 704 via a bearing, wherein:

[0102] The transmission nut of the screw mechanism is connected to the transverse cylinder 7012 to drive the transverse cylinder 7012 to rise and fall. The transmission nut is preferably connected to the transverse cylinder 7012 through a support platform. A guide belt 7010 is preferably vertically arranged on the frame, and the support platform is slidably installed on the guide belt 7010.

[0103] The output shaft of the transverse cylinder 7012 is horizontally arranged and connected to the second base, so that the transverse cylinder 7012 can drive the second base to move horizontally; the second base includes a slide 7013 and a mounting plate 7014, the slide 7013 is installed on the output shaft of the transverse cylinder 7012, and the mounting plate 7014 is installed on the slide 7013.

[0104] The lifting cylinder 7021 is installed on the frame, and the output shaft of the lifting cylinder 7021 is vertically arranged and connected to the mounting seat;

[0105] The mounting seat is slidably mounted on the second base. The mounting seat is preferably mounted on the second base via a slider 7022. The mounting seat includes a connecting block 7024, a mounting block 7028, an induction pen mounting block 7025 and a fixed plate 7023. The connecting block 7024 is mounted on the output shaft of the lifting cylinder 7021. The connecting block 7024 is fixedly mounted on the mounting block 7028. The mounting block 7028 and the induction pen mounting block 7025 are jointly mounted on the fixed plate 7023. The fixed plate 7023 is mounted on the slider 7022. A sliding surface is provided on the slider 7022. The sliding surface is in sliding contact with the mounting plate 7014, so that the slider 7022 is slidably mounted on the mounting plate 7014. The lifting cylinder 7021 pushes the connecting block 7024 to move up and down, thereby driving the mounting block 7028 to move up and down. The up and down movement of the mounting block 7028 pushes the fixing plate 7023 and the slider 7022 to move up and down, further driving the sensing pen mounting block 7025 and the two sensing pens 7016 mounted on the sensing pen mounting block 7025 to move up and down.

[0106] Two sensing pens 7016 are mounted side by side on the sensing pen mounting block 7025 of the mounting base. Each sensing pen 7016 is vertically positioned and has a conductive sensing portion at its base (the tip). The bottom ends of the conductive sensing portions of the two sensing pens 7016 are at equal heights, ensuring that the sensing pens 7016 reach the desired height after their bases descend and contact the tin surface within the tin melting pot 7026. At the moment the tips of the two sensing pens 7016 contact the tin surface within the tin melting pot 7026, the resistance between the tips of the two sensing pens 7016 reaches zero. This signals the controller, indicating that the pens 7016 have contacted the tin surface, and the lifting cylinder 7021 stops, allowing the pens 7016 to continue descending. As for obtaining the height of the sensor pen 7016 descending from the initial position to the contact with the tin surface, the descending height of the output shaft of the lifting cylinder 7021 can be measured by additionally setting a displacement sensor on the lifting cylinder 7021. Alternatively, if no additional displacement sensor is set, the maximum stroke of the output shaft of the lifting cylinder 7021 is fixed, and the output shaft of the lifting cylinder 7021 is first extended to the maximum stroke, and then the tin dipping drive motor 702 drives the sensor pen 7016 to descend to allow the sensor pen 7016 to contact the tin surface. Then, the maximum stroke of the output shaft of the lifting cylinder 7021 plus the height of the descent of the transmission nut is the distance the sensor pen 7016 descends from the initial position to the contact with the tin surface (the descending height of the sensor pen 7016), and the descending height of the transmission nut can be obtained through the second encoder 701.

[0107] Because the sensing pen 7016 and the clamping finger 7017 are simultaneously mounted on the mounting base and relatively fixed in position, the difference between the initial position of the clamping finger 7017 and the initial position of the sensing pen 7016 can be determined. Furthermore, the distance that the clamping finger 7017 and the spool cup 7027 should be lowered can be calculated. The output shaft of the lifting cylinder 7021 then retracts, causing the connecting block 7024 to move upward, thereby driving the sensing pen 7016 back to its initial position. By determining the height from the initial position of the sensing pen 7016 to the point where the sensing pen 7016 contacts the tin surface, the distance between the spool cup 7027 and the tin surface can be calculated. The height of the spool cup 7027 can then be controlled to ensure that the spool tip 137-1 of the spool cup 7027 is immersed in the tin surface while keeping the main body of the spool cup 7027 away from the tin surface, thereby improving the efficiency and quality of the tinning process for the spool cup 7027.

[0108] Transverse cylinder 7012 drives slide 7013 and mounting plate 7014 to move horizontally, thereby driving pneumatic finger 75 and sensor pen 7016 mounted on mounting plate 7014 to move horizontally. The design of transverse cylinder 7012 allows for horizontal movement of wire cup 7027 a certain distance after tinning. This prevents melted paint residue from the enameled wire from adhering to the tinned wire end 137-1 when wire cup 7027 leaves the tinning surface, potentially affecting subsequent soldering. This prevents cold solder joints and improves product yield.

[0109] The rotary cylinder 7015 is mounted on the second base, and the pneumatic finger 75 for clamping the wire cup 7027 is mounted on the output shaft of the rotary cylinder 7015. The tinning drive motor 702 and the traverse cylinder 7012 can move the wire cup 7027 and the sensor pen 7016 up, down, left, and right. The rotary cylinder 7015 can rotate the wire cup 7027 by degrees.

[0110] Furthermore, the output shaft of the rotating cylinder 7015 is installed on the cylinder clamp through the cylinder mounting plate 7014. The cylinder clamp has a cylinder body 7020 mounted on the cylinder mounting plate 7014 and two clamping fingers 7017 mounted on the cylinder body 7020. The cylinder mounting plate 7014 passes through the space between the two clamping fingers 7017. The cylinder mounting plate 7014 has a plane for receiving the splice wire cup 7027 and perpendicular to the center line of the splice wire cup 7027, so that the center line of the splice wire cup 7027 remains vertical when the splice wire cup 7027 is tinned. The cylinder body 7020 drives the two clamping fingers 7017 to open and close, thereby clamping and releasing the spool cup 7027. The cylinder body 7020 is fixedly mounted on the cylinder mounting block 7018 via a fixing block 7019. The cylinder mounting block 7018 extends from the two clamping fingers 7017 and is used to keep the spool cup 7027 held by the clamping fingers 7017 level and prevent it from tilting. This ensures that all the wire ends 137-1 of the spool cup 7027 are immersed in the tin surface during tinning, preventing them from falling. The cylinder mounting block 7018 is fixedly mounted on the rotary cylinder 7015. The rotation of the rotary cylinder 7015 drives the rotation of the cylinder mounting block 7018, which in turn drives the rotation of the clamping fingers 7017 and the spool cup 7027.

[0111] The tinning module further includes a position detection device, which is mounted on a frame and a sensor block 708 on the drive nut to detect the position of the drive nut. The photoelectric sensor B706 determines the position of the drive nut at each stop, and the second encoder 701 and tinning drive motor 702 control the height of the drive nut at each descent.

[0112] The immersion tin module also includes a gear reduction box 703. The output shaft of the immersion tin drive motor 702 is connected to the input shaft of the gear reduction box 703. The output shaft of the gear reduction box 703 is connected to the lead screw 707 via a coupling 705. The coupling 705 not only accurately transmits the torque of the output shaft of the gear reduction box 703 to the lead screw 707, but also has the advantages of buffering and speed reduction.

[0113] The production and molding process of the hollow cup using the present invention is as follows:

[0114] Multiple diamond-shaped coils are stacked together in an offset manner using the first guide post 133 of the carrier 13 and placed at the starting end 12 of the belt conveyor mechanism. The start switch 11 located above the machine is activated, and the belt conveyor mechanism delivers the carrier 13 carrying the diamond-shaped coil assembly 137 to the hot pressing module 20. Before the diamond-shaped coil assembly 137 enters the hot pressing module 20, a diverter device 24 is installed. This diverter device 24 acts as a gate, blocking the carrier 13 from flowing into the hot pressing module 20 on the conveyor belt before the first retrieving robot 25 pushes the assembled coil cake into the hot pressing module 20. This prevents the carrier 13 from being lost. When the carrier 13 carrying the diamond coil group 137 enters the lifting platform of the hot pressing module 20, the hot pressing mold 23 will first hot press the diamond coil group 137 on the lifting platform, and the diamond coil group 137 will form a patchwork wire cake. A square through hole 15 is opened at the bottom of the hot pressing module 20, which is the reflux inlet of the carrier 13. The carrier reflux conveyor belt mechanism is located below the conveying module 10. The carrier 13 reflux conveyor belt 17 is provided with a lifting platform at the reflux inlet of the carrier 13. When the diamond coil group 137 on the carrier 13 is hot pressed into a whole patchwork wire cake, the lifting platform will carry the carrier 13 downward and place it on the carrier reflux conveyor belt mechanism. At the same time, the first material picking robot 25 will clamp the patchwork wire cake to fix the patchwork wire cake so that it will not go down with the carrier 13. After the patchwork wire cake is fixed by the first material picking robot 25, the wire cutting module 26 will cut off the excess wire ends 137-1 of the patchwork wire cake according to the setting. After hot pressing is complete, the hot pressing die 23 rises, and the first retrieving robot 25 grips the wire block and places it into the cold pressing module 30. The wire end 137-1 of the wire block is placed into the first twisting chuck at the front end of the first twisting module 32. The cold pressing die 31 of the cold pressing module 30 then presses downward, solidifying the wire block and maintaining its dimensions. Once the wire block has been cold-pressed and shaped, the first retrieving robot 25 releases the wire block and returns to its previous position. The twisting chuck at the front end of the first twisting module 32 rotates, twisting the two adjacent enameled wires of the wire block together.

[0115] The hot pressing module 20, the wire cutting module 26, the cold pressing module 30 and the first wire twisting module 32 are all arranged on the same first machine 18, and the first machine 18 is provided with a first machine protective cover 41. The first machine protective cover 41 is installed with protective glass, which can play a protective role and increase the service life of the present invention. The first control panel 21 and the three-color alarm light A22 are both arranged on the machine protective cover. The first control panel 21 has functions such as start, pause, reset, and emergency stop, and can automatically set parameters or manually modify parameters, such as the hot pressing time of the hot pressing mold 23, the cold pressing time of the cold pressing mold 31, the speed of the first wire twisting chuck 32-1 in the first wire twisting module 32, the rotation time, etc. When the hot pressing module 20 or the cold pressing module 30 fails to operate, the buzzer of the first machine 18 will sound, and the three-color alarm light A22 will emit a flashing three-color light, indicating that the first machine 18 has a fault. At the same time, the entire production line will stop suddenly to ensure safety.

[0116] After the cold pressing and twisting of the wire block is complete, the second retrieving robot 33 grips the wire block and places it next to the first round rod 4011 in the center of the rounding module 40. A positioning sleeve holds the wire block against the circular mold. The rounding module 40 is equipped with a heating tube A, which heats the first round rod 4011, softening the wire block. The first rounding assembly can be set in different sequences depending on the starting position of the wire block, so that the diamond-shaped wire block is aligned end to end around the first round rod 4011, forming a cup shape. The rounding module 40 then presses the wire block again according to the settings, finalizing the shape of the wire cup 7027. Because the wire block is shaped into the wire cup 7027, the ends 137-1 at the ends of the wire block 7027 tend to be close together. Therefore, the second twisting module 43 is required to twist the two ends 137-1 together into one strand. The trimming module 48 then trims the excess ends 137-1. The processed wire cup 7027 is removed by the third retrieving robot 47. The third retrieving robot 47 is equipped with a second cylindrical guide post 4021, which is primarily used to abut against the first round rod 4011 in the rounding module 40, allowing the wire block 7027 to be removed from the first round rod 4011. After being removed by the third retrieving robot 47, the spool cup 7027 moves along the robot track 61 and is placed into the rounding module 50, where it fits over the second round rod 4017 of the rounding module 50. The arc-shaped end of the second pressing block of the rounding module 50 also has a heating tube. Heat generated by the heating tube causes the spool cup 7027 to deform again, improving its roundness and verticality, thereby ensuring its quality.

[0117] The rounding module 40 and the rounding calibration module 50 are both mounted on the same second machine 42. A second machine 42 protective cover is provided on the second machine 42, and protective glass is installed on the second machine 42 protective cover to protect the rounding module 40 and the rounding calibration module 50, thereby increasing the service life of the present invention. A second control panel 51 and a three-color alarm light B52 are both mounted on the second machine 42 protective cover. The second control panel 51 has functions such as start, pause, reset, and emergency stop, and can automatically set parameters or manually modify parameters, such as the heating temperature of the first pressing block of the rounding module 40, the operating steps of the first rounding module, the heating time of the spool 7027, the heating temperature of the second pressing block in the rounding calibration module 50, and the rounding calibration time. When a device on the second machine 42 malfunctions, the buzzer of the second machine 42 will sound, and the three-color alarm light B52 will flash three colors, indicating that the second machine 42 has malfunctioned. Simultaneously, the entire production line will be brought to an emergency stop to ensure safety.

[0118] After the spool cup 7027 is calibrated, the third retrieving robot 47 removes the spool cup 7027 and moves along the robot track 61 to place the spool cup 7027 into the cooling module 60. At the starting end 12 of the cooling module 60, the fourth retrieving robot 63 grasps the spool cup protective cover 64 and inserts it over the spool cup 7027. The spool cup protective cover 64 prevents the spool cup 7027 from suddenly cooling and causing thermal expansion and contraction, which could affect the quality of the spool cup 7027. After the spool cup protective cover 64 is inserted, the spool cup 7027, driven by the conveyor belt, passes through a row of fans 65 to cool the spool cup 7027, finalizing its shape. After cooling, the spool cup clamping device 74 grips the assembled spool cup 7027, allowing the fifth retrieving robot 68 to remove the spool cup protective cover 64 and place it on the protective cover return conveyor. The spool cup protective cover 64 then flows back to the starting end 12 of the cooling module 60 for reuse. The sixth retrieving robot 73 removes the shaped assembled spool cup 7027 and places it on the cylinder mounting block 7018 of the immersion tin module 70.

[0119] The pneumatic gripper fingers of the tinning module 70 grasp the wire cup 7027 and rotate it 180°, placing the wire end 137-1 of the wire cup 7027 facing downward. The sensor pen 7016 is used to measure the height of the sensor pen 7016 from the tin surface. The pneumatic gripper fingers then control the wire cup 7027 to move downward a certain height, lowering the wire end 137-1 below the tin surface to melt away the protective coating on the wire end 137-1. A tin scraper 77 is provided at the front end of the tin melting furnace 7026 to scrape away oxidized portions of the tin surface, making it easier for the protective coating of the enameled wire to melt away. After the wire end 137-1 of the block wire cup 7027 is dipped in tin, the pneumatic gripper rotates 180 degrees again, so that the wire end 137-1 of the block wire cup 7027 is placed face up. The seventh material-retrieving robot grips the block wire cup 7027 and places it in a tray on the side.

[0120] The cooling module 60 and the tinning module 70 are co-located on the same third machine 66. A third machine protective cover 67 is installed on the third machine 66. This cover is fitted with glass to protect the cooling module 60 and the tinning module 70, thereby increasing the service life of the present invention. A third control panel 62 and a three-color alarm light C72 are both located on the machine protective cover. The third control panel 62 has functions such as start, pause, reset, and emergency stop, and can automatically set or manually modify parameters such as the operating speed of the conveyor belt device in the cooling module 60, the temperature of the tinning furnace 7026 in the tinning module 70, and the tinning time of the spool cup 7027. If a device on the third machine 66 malfunctions, the buzzer on the third machine 66 will sound, and the three-color alarm light C72 will flash in three colors, indicating a malfunction in the third machine 66. Simultaneously, the entire production line will come to an emergency stop to ensure safety.

[0121] It will be easily understood by those skilled in the art that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
