[0005] When the present invention is in use, the cylindrical stator casing is arranged in sequence at intervals by workers and placed on the fourth conveyor belt, and moves horizontally with the fourth conveyor belt. When the stator casing moves to the discharge end of the fourth conveyor belt, the stator casing manipulator grabs the stator casing and sends it to the stator casing loading station on the turntable. The turntable rotates a certain angle under the action of the motor, so that the stator casing on the stator casing loading station rotates with the turntable to the magnetic steel loading station; at the same time, the workers also place arc-shaped tile-shaped magnetic steel sheets vertically at the same intervals on the first conveyor belt and the third conveyor belt in sequence, to realize unidirectional transportation. When the magnetic steel sheets on the third conveyor belt move to the discharge section of the third conveyor belt, the pushing cylinder drives the pushing plate to move forward, and pushes the magnetic steel sheets on the discharge section of the third conveyor belt onto the second conveyor belt. The orientation of the magnetic steel sheets entering the second conveyor belt is relatively matched with the orientation of the magnetic steel sheets on the first conveyor belt, and the action of the second conveyor belt and the first conveyor belt The two magnetic steel sheets are moved relatively close to each other until they move to the magnetic steel grabbing station. The magnetic steel manipulator grabs the two matching magnetic steel sheets at the same time and sends them to the magnetic steel loading station on the turntable, so that the two matching magnetic steel sheets are inserted into the stator housing accordingly. Then the turntable rotates a certain angle to transport the stator housing and the magnetic steel on the magnetic steel loading station to the fixture loading station along with the rotation of the turntable. The fixtures are arranged in sequence by the workers at intervals and move horizontally along the fifth conveyor belt. When the fixtures are transported to the fifth conveyor belt, When it reaches the discharging end of the fifth conveyor belt, the clamp robot grabs the clamp and sends it to the clamp loading station on the turntable, thereby inserting the clamp into the inner cavity composed of the magnetic steel sheets. The clamp robot releases the clamp, and the outer support of the clamp has a supporting force on the magnetic steel sheet, so that the gap between the magnetic steel sheet and the stator shell is small. Then the turntable rotates, and the stator workpiece at the rear end of the assembly on the clamp loading station on the turntable is transferred to the unloading station of the turntable, and is grabbed by the unloading robot and sent to the sixth conveyor belt for output and packaging.

[0006] Furthermore, the stator casing loading robot, magnetic steel loading robot, fixture loading robot and unloading robot all include a bracket, a screw pair, a servo motor, a connecting bracket, a pneumatic finger manipulator and a clamping component. Both ends of the screw of the screw pair are mounted on the bracket through bearing supports, the top end of the screw is fixedly connected to the motor shaft of the servo motor fixedly mounted on the bracket, the connecting bracket is fixedly connected to the nut seat of the screw pair, the top end of the pneumatic finger manipulator is mounted on the connecting bracket, the pneumatic finger manipulator includes two fingers that can approach or move away in a straight line, the clamping component includes a left jaw and a right jaw, the left jaw and the right jaw are respectively fixedly mounted on two fingers of the pneumatic finger manipulator, the servo motor drives the screw to rotate, thereby driving the connecting bracket to move up and down with the nut seat of the screw pair, and the pneumatic finger manipulator drives the left jaw and the right jaw to approach or move away, thereby achieving clamping and loosening of the workpiece.

[0007] The left jaw and the right jaw of the stator casing feeding robot are both rod-shaped members with the axial direction being vertical. The tops of the left jaw and the right jaw are fixedly connected to the two fingers by screws respectively. When the left jaw and the right jaw extend into the inner cavity of the stator casing, the pneumatic finger robot drives the left jaw and the right jaw to move away in a straight line so that the left jaw and the right jaw respectively abut against the inner cavity wall of the stator casing, thereby clamping the stator casing for lifting and lowering movements and lateral conveying movements. When the stator casing is conveyed to the stator casing feeding station on the turntable, the pneumatic finger robot drives the left jaw and the right jaw to move close in a straight line so as to release the stator casing, thereby completing the loading action of the stator casing.

[0008] The magnetic steel feeding robot also includes a rotating motor, which is arranged between the connecting bracket and the pneumatic finger robot. The top of the pneumatic finger robot is fixedly connected to the motor shaft of the rotating motor. The body of the rotating motor is fixedly installed on the connecting bracket. The rotating motor drives the motor shaft to rotate, thereby driving the pneumatic finger robot to rotate.

[0009] The left and right jaws of the magnetic steel feeding manipulator are cylindrical bodies with bow-shaped cross-sections, the tops of the left and right jaws are fixedly connected to the two fingers respectively, the side planes of the left and right jaws are arranged opposite to each other, and a magnet is fixedly embedded in the middle of the outer curved surface of each of the left and right jaws; when the left and right jaws are simultaneously extended between the two opposite magnetic steel sheets on the magnetic steel grasping station, the inner curved surface of the magnetic steel sheet on the left side is abutted against the outer curved surface of the left jaw and connected as a whole under the action of the magnetic force of the magnet, and the inner curved surface of the magnetic steel sheet on the right side is abutted against the outer curved surface of the right jaw and connected as a whole under the action of the magnetic force of the magnet, and the pneumatic finger manipulator drives the left and right jaws to approach and perform lifting and lowering movements and lateral conveying movements. When the two magnetic steel sheets are transported to the magnetic steel loading station on the turntable, the servo motor is started to drive the pneumatic finger manipulator to descend. During the descent, the rotating motor drives the pneumatic finger manipulator to rotate, and the glue spraying machine on the side discharges glue to achieve gluing on the outer curved surface of the magnetic steel sheet, and finally extends into the inner cavity of the stator shell on the magnetic steel loading station. The pneumatic finger manipulator drives the left jaw and the right jaw to move away so that the two magnetic steel sheets are respectively attached to the inner cavity wall of the stator shell, and then the pneumatic finger manipulator drives the left jaw and the right jaw to move closer. Since the magnet is a weak magnet, the magnetic force is less than the bonding force of the glue between the magnetic steel sheet and the stator shell, so that the left jaw and the right jaw are moved away from the two magnetic steel sheets and move upward, completing the loading and gluing actions of the magnetic steel sheets.

[0010] The left jaw and the right jaw of the fixture loading robot are both rod-shaped parts with the axis in the vertical direction. The tops of the left jaw and the right jaw are fixedly connected to the two fingers by screws respectively. When the left jaw and the right jaw are inserted into the two clamping holes on the fixture, the pneumatic finger robot drives the left jaw and the right jaw to approach in a straight line so that the left clamp block and the right clamp block corresponding to the left jaw and the right jaw are respectively abutted, thereby clamping the fixture for lifting and lowering movements and lateral conveying movements. When the fixture is conveyed to the fixture loading station on the turntable, it moves downward so that the fixture is extended into the inner cavity of the stator housing on the fixture loading station. The servo motor is started to drive the pneumatic finger robot to move upward to release the fixture. The left clamp block and the right clamp block of the fixture are elastically pressed against the left magnetic steel sheet and the right magnetic steel sheet under the action of the spring to complete the loading action of the fixture.

[0011] The left and right jaws of the unloading robot are both rod-shaped parts with the axis in the vertical direction. The tops of the left and right jaws are fixedly connected to the two fingers by screws respectively. When the left and right jaws are extended into the two clamping holes on the fixture in the stator shell on the unloading station, the pneumatic finger robot drives the left and right jaws to move away in a straight line so that the left and right jaws respectively generate an outward supporting force on the left clamp block and the right clamp block, thereby clamping the fixture, the magnetic steel sheet and the stator shell as a whole for lifting and lowering movements and lateral conveying movements. When the fixture is conveyed to the feed end of the sixth conveyor belt, the pneumatic finger robot drives the left and right jaws to approach so that the supporting force on the left and right clamp blocks is lost, and the pneumatic servo motor drives the pneumatic fingers to move upward, thereby outputting the fixture, the magnetic steel sheet and the stator shell as a whole, completing the unloading action.

[0012] The fourth conveyor belt, the fifth conveyor belt and the sixth conveyor belt are provided with ovens, which heat the stator shell, the clamp, and the stator finished product consisting of the stator shell and the magnetic steel sheet during the conveying process, thereby shortening the curing time of the glue and increasing the firmness.

[0013] The following beneficial effects can be achieved by using the present invention: the magnetic steel and the stator shell are transported separately by a conveyor belt, thereby improving the degree of automation, and only one worker is needed to place the magnetic steel and the stator shell on the conveyor belt, thereby reducing labor costs and reducing the work intensity of workers; by pairing the two magnetic steel sheets and transporting them in relative directions, it is convenient for the robot to clamp them and improve stability.
