The upper side of the blanking plate and the lower side of the shell are matched in shape, and the blanking plate is located above the finished product conveyor line, and the blanking plate is limited by the assembly box.

[0008] The structures of the first conveyor line, the second conveyor line and the finished product conveyor line are the same. The first conveyor line includes rollers and transmission belts. The rollers are provided in multiple groups. The multiple groups of rollers are installed on the frame. The inner sides of the transmission belts are in contact with the rollers. The interior of the rollers is an electric roller structure. The multiple groups of rollers are equipped with encoders and pressure sensors.

[0009] The transmission belts on the first conveyor line and the second conveyor line are equipped with multiple groups of follower plates, which are hollow inside. The follower plates are provided with filling ports, which are connected to the inside of the follower plates. The follower plates are provided with storage slots, and the follower plates near the bottom of the storage slots are provided with multiple groups of adsorption holes and proximity sensors, which are installed on one side of the multiple groups of adsorption holes. The multiple groups of adsorption holes are connected to the air source system through pipelines, and the air source system is installed on the frame. Isolation membranes and third coils are installed around the storage slots, and the third coil is located on one side of the isolation membrane. The isolation membrane and the third coil are both installed inside the follower plate, and the isolation membrane is made of flexible material, and the third coil is electrically connected to the control system.

[0010] The first electric cylinder is mounted on the frame, a sliding plate is mounted on the output shaft of the first electric cylinder, the sliding plate is slidably connected to the frame, the sliding plate is limited by the frame, the second electric cylinder is mounted on both sides of the sliding plate, and the suction cup plates are mounted on the output shafts of the two groups of second electric cylinders; Multiple groups of second suction cups are installed on both sides of the suction cup plate, and the multiple groups of second suction cups are connected to the air source system through pipes. A glue injection cylinder is installed above the second suction cup, and the glue injection cylinder is connected to the upper side of the liquid storage tank through a pipe and a flow meter. The flow meter is installed in the pipe connected to the glue injection cylinder, and the glue injection cylinder is connected to the glue on the upper side of the liquid storage tank through a pipe.

[0011] The floating plate is always in contact with the liquid surface of the glue due to its own weight. A sliding groove is provided on the liquid storage tank outside the floating plate. The metal plate passes through the sliding groove. The floating plate is slidably connected to the liquid storage tank through the sliding groove and a spring. Multiple groups of telescopic plates are installed on the floating plate. The multiple groups of telescopic plates are opposite to the sliding groove. The telescopic plates block the sliding groove, and the multiple groups of telescopic plates prevent glue from entering the sliding groove.

[0012] Place multiple shells on the storage slot on the follower plate (the follower plate on the second conveyor line), the shells contact the multiple groups of adsorption holes at the bottom of the storage slot, the proximity sensor in the storage slot feeds back data to the control system, the control system controls the air source system to work, the first coil to be energized and the control valve at the bottom of the liquid storage tank to open, and negative pressure is generated in the multiple groups of adsorption ports through the air source system and the pipeline, and the multiple groups of adsorption ports adsorb the shells. The magnetic field generated by the first coil after energization and the magnetic field of the second magnet on the second lifting plate repel each other, and the magnetic field of the first coil pushes the second lifting plate to move to the lower side, so that the magnetorheological fluid on the lower side of the second lifting plate enters the interior of the follower plate through the pipeline, the control valve and the filling port, and the magnetorheological fluid squeezes the isolation membrane to protrude to one side of the shell, so that the isolation membrane is attached to the shell, and the multiple groups of isolation membranes adapt to the shape of the outside of the shell and contact.

[0013] When the sensor A at the bottom of the liquid storage tank detects that the second lifting plate moves to the lowest side, the control system energizes the third coil. The magnetic field generated by the third coil causes the magnetorheological fluid in the follower plate to change from liquid to solid. The solid magnetorheological fluid clamps the shell through the isolation membrane, and the shell is adsorbed through the adsorption holes while being positioned and clamped, thereby improving the positioning accuracy of the shell and ensuring the stability of the shell movement on the transmission belt. Similarly to placing the shell on the second conveyor line, the core package is placed on the storage slot on the follower plate (the follower plate on the first conveyor line).

[0014] When the core package and the shell are placed on the first conveyor line and the second conveyor line respectively, the control system drives the transmission belts on both sides to move according to the data of the encoders inside the rollers on both sides, and the transmission belts on both sides drive the follower plates on both sides to move, so that the shell and the core package on the follower plates on both sides move to the two sides of the suction cup plate. Afterwards, the control system controls the first electric cylinder to drive the sliding plate to move, and the sliding plate drives the second electric cylinder and the suction cup plate to move to the side close to the shell, and the second electric cylinder drives the suction cup plate to move to the middle of the shell, so that the second suction cup on the left side of the suction cup plate contacts the middle of the shell, and the second suction cup on the left side of the suction cup plate cooperates with the air source system to adsorb the shell. Afterwards, the same as the second suction cup on the left side adsorbs the shell, the cooperation of the first electric cylinder and the second electric cylinder drives the second suction cup on the right side to adsorb the core package, so that the second suction cups on both sides of the suction cup plate adsorb the shell and the core package respectively.

[0015] After the second suction cups on both sides absorb the shell and the core package, the sensor in the second suction cup on the left side feeds back data to the control system. The control system drives the suction cup plate and the shell to the top of the feeding trough through the cooperation of the first electric cylinder and the second electric cylinder. After that, the second electric cylinder drives the shell to move downward through the suction cup plate, so that the lower side of the shell enters the feeding trough.

[0016] When the shell or core package is adsorbed by the second suction cup, the proximity sensor on the follower plate feeds back data to the control system, the control valve on the lower side of the liquid storage tank is opened, the first coil is energized with reverse current and the third coil is powered off. After the third coil is powered off, the magnetorheological fluid in the follower plate changes from solid to liquid, and the magnetic field generated by the reverse current of the first coil attracts the second magnet on the second lifting plate, so that the second magnet drives the second lifting plate to move upward, and the magnetorheological fluid in the follower plate is extracted to the lower side of the second lifting plate through the pipeline and the control valve. The isolation membrane is in a flat state under the action of its own elastic force. After that, the control system controls the control valve on the lower side of the liquid storage tank to close to prevent the magnetorheological fluid from flowing out.

[0017] When the lower side of the shell enters the feeding trough, the displacement sensor on one side of the feeding trough feeds back data to the control system, and the control system controls the control valve on the upper side of the liquid storage tank to open and the first coil to be energized. The magnetic field generated after the first coil is energized repel each other with the first magnet on the first lifting plate, and the first magnet drives the first lifting plate to move upward under the action of the repulsive force, and the first lifting plate drives the glue to pass through the pipeline and the upper control valve into the glue injection cylinder, and the glue injection cylinder sprays the glue inside the shell. After spraying to the set capacity, the flow meter in the pipeline connected to the glue injection cylinder feeds back data to the control system, and the control system sequentially passes reverse electricity to the first coil, and the magnetic field generated by the reverse current passed through the first coil attracts each other with the first magnet on the first lifting plate, and the first magnet drives the first lifting plate to move downward to extract the remaining glue in the pipeline to the upper side of the liquid storage tank. After that, the control system controls the control valve on the upper side of the liquid storage tank to close to prevent the glue from flowing out.

[0018] After the glue is injected into the shell, the air source system will exhaust the second suction cup that adsorbs the shell, so that the shell falls from the feeding trough and falls on the unloading plate. The visual camera on the fixed plate identifies the position and size of the shell, and feeds back the data to the control system, which controls the positioning electric cylinder on the lower side to work according to the data. The output shafts of the multiple groups of positioning electric cylinders on the lower side push the rotating plate and the first suction cup to move toward the shell. The first suction cup and the air source system cooperate to adsorb the shell. The multiple groups of positioning electric cylinders on the lower side push the first shell to the inner wall of the feeding trough through the rotating plate and the first suction cup, and the multiple groups of positioning electric cylinders on the lower side position the shell through the rotating plate and the first suction cup.

[0019] After the shell is positioned, the visual camera feeds back the data to the control system. The control system drives the lower side of the core package into the feeding trough through the cooperation of the first electric cylinder and the second electric cylinder. After that, the control system exhausts the second suction cup on the right side of the suction cup plate through the air source system, and the second suction cup on the right side no longer adsorbs the core package. The core package falls from the feeding trough and falls on the raised position in the feeding trough, which is flush with the top of the shell. After that, the visual camera identifies the position, pins and size data of the core package, and feeds back the data to the control system to achieve rapid positioning of the pins. The control system controls the multiple groups of positioning electric cylinders on the upper side to drive the rotating plate and the first suction cup to move toward one side of the core package. The first suction cup on the upper side cooperates with the air source system to achieve the adsorption of the core package. The first suction cup on the upper side adsorbs the core package. After that, the multiple groups of upper positioning electric cylinders drive the core package to move to the top of the shell through the rotating plate and the first suction cup, so that the lower side of the core package is facing the inside of the shell. After that, the control system controls the pressing electric cylinder to drive the fixed plate to move downward. When the fixed plate moves downward, it pushes the core package into the shell to realize the assembly production of the core package and the shell.

[0020] When the core package and the shell are assembled, the visual camera feeds data back to the control system. The control system controls the discharge spring to be energized. After the discharge spring is energized, a mutually attractive magnetic field is generated between each turn. The magnetic field compresses the discharge spring, causing the discharge spring to contract. The discharge spring pulls the discharge plate to move away from the feeding trough, so that the finished product of the core package and the shell assembly falls on the finished product conveyor line and is transported out through the finished product conveyor line.

[0021] After assembly, the control system connects the second coil and the metal plate to the circuit. The current enters from one end of the second coil, flows through the effective turns of the second coil, and then flows out from the metal plate. The control system detects the current and then obtains the position of the floating plate. The control system can calculate the capacity of the remaining glue and feed the data back to the control system.

[0022] A magnetic shielding material is provided on one side of the second lifting plate close to the magnetorheological fluid and on the inner wall of the frame to prevent the magnetorheological fluid from being affected by the magnetic field of the first coil. The lower side of the liquid storage tank is connected to the filling port through a pipeline, and the magnetorheological fluid on the lower side of the liquid storage tank is connected to the inside of the follower plate through the pipeline and the filling port. A control valve is installed in the pipeline connected to the liquid storage tank, and the control valve is electrically connected to the control system.

[0023] The frame is provided with a control panel, and a control system is arranged in the control panel. The magnetic field generated by the third coil causes the magnetorheological fluid in the follower plate to change from liquid to solid, and the magnetorheological fluid in solid state clamps the shell through the isolation membrane, and the shell is adsorbed through the adsorption hole while being positioned and clamped, thereby improving the positioning accuracy of the shell and ensuring the stability of the shell moving on the transmission belt.

[0024] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. Automatic glue injection, convenient and fast. The magnetic field generated by the first coil after being energized repel the first magnet on the first lifting plate. The first magnet drives the first lifting plate upward under the action of the repulsive force. The first lifting plate drives the glue to enter the glue injection cylinder through the pipeline and the control valve on the upper side. The glue injection cylinder sprays the glue inside the shell. After spraying to the set capacity, the flow meter in the pipeline connected to the glue injection cylinder feeds back the data to the control system. The control system sequentially passes reverse electricity to the first coil. The magnetic field generated by the reverse current of the first coil attracts the first magnet on the first lifting plate. The first magnet drives the first lifting plate downward to extract the remaining glue in the pipeline to the upper side of the liquid storage tank. After that, the control system controls the control valve on the upper side of the liquid storage tank to close to prevent the glue from flowing out.

[0025] 2. Automated assembly with high assembly efficiency. The core package falls from the feeding trough and lands on a raised position in the feeding trough that is flush with the top of the shell. After that, the visual camera identifies the position, pins and size data of the core package, and feeds the data back to the control system to achieve rapid positioning of the pins. The control system controls multiple groups of positioning electric cylinders on the upper side to drive the rotating plate and the first suction cup to move toward one side of the core package. The first suction cup on the upper side and the air source system cooperate to achieve the adsorption of the core package. The first suction cup on the upper side adsorbs the core package. After that, multiple groups of upper positioning electric cylinders drive the core package to move to the top of the shell through the rotating plate and the first suction cup, so that the lower side of the core package is facing the inside of the shell. After that, the control system controls the pressing electric cylinder to drive the fixed plate to move downward. When the fixed plate moves downward, it pushes the core package into the shell to achieve the assembly production of the core package and the shell.

[0026] 3. Adsorption positioning and flexible clamping ensure the positioning accuracy of the core package and the shell. The magnetic field generated by the third coil changes the magnetorheological fluid in the follower plate from liquid to solid. The solid magnetorheological fluid clamps the shell through the isolation membrane, and the shell is adsorbed through the adsorption holes while being positioned and clamped, which improves the positioning accuracy of the shell and ensures the stability of the shell's movement on the transmission belt.

[0036] The working principle of the present invention is as follows: a plurality of shells 17 are placed on the storage slot 231 on the follower plate 23 (the follower plate 23 on the second conveying line 21), the shell 17 contacts the plurality of adsorption holes at the bottom of the storage slot 231, the proximity sensor in the storage slot 231 feeds back data to the control system, the control system controls the air source system to work, the first coil 152 to be energized, and the control valve at the lower side of the liquid storage tank 15 to be opened, and negative pressure is generated by the plurality of adsorption ports through the air source system and the pipeline, and the plurality of adsorption ports adsorb the shell 17, the magnetic field generated by the first coil 152 after being energized and the magnetic field of the second magnet on the second lifting plate 153 repel each other, the magnetic field of the first coil 152 pushes the second lifting plate 153 to move to the lowermost side, so that the magnetorheological fluid at the lower side of the second lifting plate 153 enters the interior of the follower plate 23 through the pipeline, the control valve and the filling port 26, the magnetorheological fluid squeezes the isolation membrane 232 to protrude to one side of the shell 17, so that the isolation membrane 232 is attached to the shell 17, and the plurality of isolation membranes 231 adapt to the shape of the outer side of the shell 17 and contact.

[0037] When the sensor A at the bottom of the liquid storage tank 15 detects that the second lifting plate 153 moves to the lowermost side, the control system energizes the third coil 233. The magnetic field generated by the third coil 233 causes the magnetorheological fluid in the follower plate 23 to change from liquid to solid. The solid magnetorheological fluid clamps the shell 17 through the isolation membrane 232, and positions and clamps the shell 17 while adsorbing it through the adsorption holes, thereby improving the positioning accuracy of the shell 17 and ensuring the stability of the shell 17 moving on the transmission belt 24. Similarly to placing the shell 17 on the second conveyor line 21, the core package 16 is placed on the storage slot 231 on the follower plate 23 (the follower plate 23 on the first conveyor line 2).

[0038] When the core package 16 and the shell 17 are placed on the first conveyor line 2 and the second conveyor line 21 respectively, the control system drives the transmission belts 24 on both sides to move according to the data of the encoders inside the rollers 25 on both sides, and the transmission belts 24 on both sides drive the following plates 23 on both sides to move, so that the shell 17 and the core package 16 on the following plates 23 on both sides move to the two sides of the suction cup plate 27. After that, the control system controls the first electric cylinder 12 to drive the sliding plate 14 to move, and the sliding plate 14 drives the second electric cylinder 13 and the suction cup plate 27 to move to the side close to the shell 17. The second electric cylinder 13 drives the suction cup plate 27 to move to the middle of the shell 17, so that the second suction cup on the left side of the suction cup plate 27 contacts the middle of the shell 17, and the second suction cup on the left side of the suction cup plate 27 cooperates with the air source system to adsorb the shell 17. After that, the same as the second suction cup on the left side adsorbs the shell 17, the cooperation of the first electric cylinder 12 and the second electric cylinder 13 drives the second suction cup on the right side to adsorb the core package 16, so that the second suction cups on both sides of the suction cup plate 27 adsorb the shell 17 and the core package 16 respectively.

[0039] After the second suction cups on both sides absorb the shell 17 and the core package 16, the sensor in the second suction cup on the left side feeds back data to the control system. The control system drives the suction cup plate 27 and the shell 17 to move above the feeding trough 33 through the cooperation of the first electric cylinder 12 and the second electric cylinder 13. After that, the second electric cylinder 13 drives the shell 17 to move downward through the suction cup plate 27, so that the lower side of the shell 17 enters the feeding trough 33.

[0040] When the shell 17 or the core package 16 is adsorbed by the second suction cup, the proximity sensor on the follower plate 23 feeds back data to the control system, the control valve on the lower side of the liquid storage tank 15 is opened, the first coil 152 is energized with reverse current, and the third coil 233 is powered off. After the third coil 233 is powered off, the magnetorheological fluid in the follower plate 23 changes from solid to liquid. The magnetic field generated by the reverse current of the first coil 152 attracts the second magnet on the second lifting plate 153, so that the second magnet drives the second lifting plate 153 to move upward, and the magnetorheological fluid in the follower plate 23 is extracted to the lower side of the second lifting plate 153 through the pipeline and the control valve. The isolation membrane 232 is in a flat state under the action of its own elastic force. After that, the control system controls the control valve on the lower side of the liquid storage tank 15 to close to prevent the magnetorheological fluid from flowing out.

[0041] When the lower side of the shell 17 enters the feeding trough 33, the displacement sensor 34 on one side of the feeding trough 33 feeds back data to the control system, and the control system controls the control valve on the upper side of the liquid storage tank 15 to open and the first coil 152 to be energized. The magnetic field generated by the first coil 152 after being energized repel each other with the first magnet on the first lifting plate 151. The first magnet drives the first lifting plate 151 to move upward under the action of the repulsive force, and the first lifting plate 151 drives the glue to pass through the pipeline and the upper control valve into the glue injection cylinder 18. The glue injection cylinder 18 sprays the glue inside the shell 17. After spraying to the set capacity, the flow meter in the pipeline connected to the glue injection cylinder 18 feeds back data to the control system, and the control system sequentially passes reverse electricity into the first coil 152. The magnetic field generated by the reverse current passed into the first coil 152 attracts each other with the first magnet on the first lifting plate 151, and the first magnet drives the first lifting plate 151 to move downward to extract the remaining glue in the pipeline to the upper side of the liquid storage tank 15. After that, the control system controls the control valve on the upper side of the liquid storage tank 15 to be closed to prevent the glue from flowing out.

[0042] After the glue is injected into the shell 17, the air source system will exhaust the second suction cup that adsorbs the shell 17, so that the shell 17 falls from the feeding trough 33, and the shell 17 falls on the unloading plate 38. The visual camera 31 on the fixed plate 36 identifies the position and size of the shell 17, and feeds back the data to the control system, which controls the positioning electric cylinder 37 on the lower side to work according to the data. The output shafts of the multiple groups of positioning electric cylinders 37 on the lower side push the rotating plate 32 and the first suction cup to move toward the shell 17. The first suction cup and the air source system cooperate to adsorb the shell 17. The multiple groups of positioning electric cylinders 37 on the lower side push the first shell 17 to the inner wall of the feeding trough 33 through the rotating plate 32 and the first suction cup, and the multiple groups of positioning electric cylinders 37 on the lower side position the shell 17 through the rotating plate 32 and the first suction cup.

[0043] After the shell 17 is positioned, the visual camera 31 feeds back data to the control system, and the control system drives the lower side of the core package 16 into the feeding trough 33 through the cooperation of the first electric cylinder 12 and the second electric cylinder 13. After that, the control system will exhaust the second suction cup on the right side of the suction cup plate 27 through the air source system, and the second suction cup on the right side will no longer adsorb the core package 16, and the core package 16 will fall from the feeding trough 33. The core package 16 falls on the raised position in the feeding trough 33, which is flush with the top of the shell 17. After that, the visual camera 31 identifies the position, pins and size data of the core package 16, and feeds back the data to the control system to achieve rapid pin positioning. Positioning, the control system controls the multiple groups of positioning electric cylinders 37 on the upper side to drive the rotating plate 32 and the first suction cup to move toward the side of the core package 16, and the first suction cup on the upper side cooperates with the air source system to realize the adsorption of the core package 16. The first suction cup on the upper side adsorbs the core package 16, and then the multiple groups of positioning electric cylinders 37 on the upper side drive the core package 16 to move above the shell 17 through the rotating plate 32 and the first suction cup, so that the lower side of the core package 16 is facing the inside of the shell 17, and then the control system controls the pressing electric cylinder 35 to drive the fixed plate 36 to move downward, and when the fixed plate 36 moves downward, it pushes the core package 16 into the inside of the shell 17, thereby realizing the assembly production of the core package 16 and the shell 17.

[0044] When the core package 16 and the shell 17 are assembled, the visual camera 31 feeds data back to the control system. The control system controls the discharge spring 381 to be energized. After the discharge spring 381 is energized, a mutually attractive magnetic field is generated between each turn. The magnetic field compresses the discharge spring 381, causing the discharge spring 381 to contract. The discharge spring 381 pulls the discharge plate 38 to move away from the feeding trough 33, so that the finished product assembled with the core package 16 and the shell 17 falls on the finished product conveyor line 22 and is conveyed out through the finished product conveyor line 22.

[0045] After assembly, the control system connects the second coil 156 and the metal plate 155 to the circuit. The current enters from one end of the second coil 156, flows through the effective turns of the second coil 156, and then flows out from the metal plate 155. The control system detects the current and obtains the position of the floating plate 154. The control system can calculate the capacity of the remaining glue and feed the data back to the control system. When the capacity is insufficient, remove the pipe on the upper side of the liquid storage tank 15 and add glue.
