The outer diameter of the first gear 13 is smaller than the inner diameter of the screw groove 10. The robot is controlled to place the pressing plate 5 inside the positioning slot 6 on the left, and each clamping block 9 is inserted into each clamping slot 7 to prevent the pressing plate 5 from rotating. The coil winding is then placed on the top of the bottom plate 3 and outside the screw 4 by the robot. When the bottom plate 3 rotates to the rear, the pressing plate 5 is placed outside the extension column 12 , that is, at the top end of the screw rod 4 , by the robot.

[0022] The linkage limiting mechanism is installed on the base plate 3 and is used to limit the coil winding externally. The linkage limiting mechanism includes a plurality of slide grooves 14 opened on the top of the base plate 3, a plurality of transmission shafts 15 respectively connected to the inside of the plurality of slide grooves 14, a plurality of limiting bars 16 respectively arranged on the outside of the plurality of transmission shafts 15, and a linkage component for driving the plurality of transmission shafts 15 to rotate; the plurality of limiting bars 16 are distributed in a circular array with the screw 4 as the center; a reciprocating screw 17 is fixedly sleeved on the outside of the transmission shaft 15, the limiting bar 16 is screwed to the outside of the reciprocating screw 17, and the limiting bar 16 is also slidably connected to the inner wall of the slide groove 14, and the linkage component includes a structural groove 18 opened on the inside of the base plate 3 and a rotationally connected A drive shaft 19 inside the screw 4; one end of each of the multiple transmission shafts 15 extends into the interior of the structural groove 18 and is fixedly connected to a first bevel gear 20; the bottom end of the drive shaft 19 extends into the interior of the structural groove 18 and is fixedly connected to a second bevel gear 21, the second bevel gears 21 are respectively meshed with the multiple first bevel gears 20, and the multiple first bevel gears 20 do not mesh with each other, the top end of the drive shaft 19 extends to the outside of the extension column 12 and is fixedly connected to a second gear 22; a first bracket 23 is fixedly connected to the top of the base 1, and a tooth arc 24 is fixedly connected to the outer wall of the first bracket 23. When the turntable 2 rotates, it drives the second gear 22 to mesh with the tooth arc 24, and the outer diameter of the second gear 22 is smaller than the inner diameter of the screw groove 10; After the coil winding is placed on the top of the base plate 3, the turntable 2 is driven to rotate a quarter of a turn and then stop by controlling the first motor 8. In this process, the driving shaft 19 is driven to rotate by the meshing effect between the second gear 22 and the tooth arc 24. The second bevel gear 21 is respectively meshed with the four first bevel gears 20 to drive the four transmission shafts 15 to rotate synchronously. The four reciprocating screws 17 rotate synchronously therewith, and then drive each limit bar 16 to move from the end of the reciprocating screw 17 away from the screw 4 to the end thereof close to the screw 4, that is, drive the four limit bars 16 to approach each other, perform center positioning and external limit on the coil winding, and prevent the coil winding from deforming outward during the pressure process; When placing the pressure plate 5 later, the four limiting grooves 11 on the outer wall of the pressure plate 5 are respectively placed on the outside of the four limiting strips 16, and the four limiting strips 16 are equivalent to limiting the pressure plate 5, so that when the screw 4 rotates, the pressure plate 5 will not rotate with it, but will only move downward along the outer wall of each limiting strip 16.

[0023] A drive mechanism is mounted on top of the base 1 and is used to drive the screw 4 to rotate. The drive mechanism includes a second bracket 25 mounted on top of the base 1, a second motor 26 mounted on top of the second bracket 25, and a gear plate 27 fixed to the output end of the second motor 26; the gear plate 27 cooperates with the first gear 13; two cylinders 28 are also mounted inside the second bracket 25, and a pressure block 29 is fixed to the extended end of each cylinder 28; After the pressing plate 5 is placed, the first motor 8 continues to drive the turntable 2 to rotate a quarter of a turn and then stops. At this time, the first gear 13 is engaged with the toothed disc 27. The two cylinders 28 are controlled to drive the pressure block 29 to move down and abut against the top of the pressing plate 5, so that the pressing plate 5 remains horizontal. The second motor 26 is then controlled to drive the toothed disc 27 to rotate. The toothed disc 27 is engaged with the first gear 13, which drives the extension column 12 to rotate, and then drives the screw 4 to rotate. The limiting bar 16 limits the pressing plate 5, so that the pressing plate 5 moves downward, pressing the coil winding at the bottom. A detachable limit rod can be installed inside the second bracket 25, and a corresponding rod groove is opened inside the pressure plate 5. When the coil winding is dried and needs to be removed from the constant pressure forming mechanism, and the coil winding rotates to the bottom of the pressure block 29, the limit rod is fixed inside the second bracket 25 and inserted into the inside of the rod groove to limit the pressure plate 5. When the screw 4 rotates, it drives the pressure plate 5 to move up and disengage from the screw, and then the limit rod is removed, and the turntable 2 is driven to rotate a quarter of a turn and then stop, and the pressure plate 5, coil winding and bottom plate 3 are removed in turn by the robot.

[0024] A third bracket 30 is also installed on the top of the base 1, and a laser sensor 31 is installed on the third bracket 30; When the laser sensor 31 detects that the pressing plate 5 moves downward to the set position, the second motor 26 is controlled to be turned off, and the pressing plate 5 stops moving downward.

[0025] The auxiliary limiting mechanism is connected to the linkage limiting mechanism and is used to limit the top of the pressing plate 5 after the pressing plate 5 presses the coil winding. The auxiliary limiting mechanism includes a hidden groove 32 provided on the outer wall of the limiting strip 16 on the side close to the screw 4 and a limiting block 33 slidably connected to the inside of the hidden groove 32; a plurality of springs 34 are fixedly connected to the inner wall of one side of the hidden groove 32, and the other end of the spring 34 is fixedly connected to the outer wall of the limiting block 33; the top of the limiting block 33 on the side close to the screw 4 is provided with an inclined groove 35; When the pressure plate 5 moves downward and abuts the inclined groove 35, the limit block 33 is driven to slide toward the inside of the hidden groove 32, and the spring 34 is compressed accordingly. The pressure plate 5 passes the limit block 33 and reaches the set position. At this time, the rebound force of the spring 34 drives the limit block 33 to slide out from the inside of the hidden groove 32 and abut the top of the pressure plate 5, limiting the top of the pressure plate 5, thereby assisting the screw 4 to ensure that the pressure plate 5 will not move subsequently, reducing the bearing force on the screw 4.

[0026] Working principle: The pressure plate 5 is placed inside the positioning slot 6 on the left side by controlling the manipulator, and each card block 9 is inserted into each card slot 7 to prevent the subsequent pressure plate 5 from rotating. Then the coil winding is placed on the top of the bottom plate 3 by the manipulator, and is located on the outside of the screw 4. The turntable 2 is driven to rotate a quarter of a turn and then stop by controlling the first motor 8. In this process, the driving shaft 19 is driven to rotate by the meshing effect between the second gear 22 and the tooth arc 24. The second bevel gear 21 is meshed with the four first bevel gears 20 respectively, which drives the four transmission shafts 15 to rotate synchronously. The four reciprocating screws 17 rotate synchronously with it, thereby driving each limit bar 16 moves from the end of the reciprocating screw 17 away from the screw 4 to the end thereof close to the screw 4, that is, drives the four limit bars 16 to approach each other, performs center positioning and external limit on the coil winding, and prevents the coil winding from deforming outward during the pressure process. When the turntable 2 stops, the four limit grooves 11 on the outer wall of the pressure plate 5 are respectively sleeved on the outside of the four limit bars 16 by the manipulator, and the four limit bars 16 are equivalent to limiting the pressure plate 5. Then, the turntable 2 is driven by the first motor 8 to continue to rotate a quarter of a turn and then stop. At this time, the first gear 13 is engaged with the toothed disc 27, and the pressure block 29 is driven to move down and abut against the pressure plate by controlling the two cylinders 28. 5, so that the pressure plate 5 remains horizontal, and then the gear plate 27 is driven to rotate by controlling the second motor 26. The engagement between the gear plate 27 and the first gear 13 drives the extension column 12 to rotate, and then drives the screw 4 to rotate, and the limiting effect of the limiting bar 16 on the pressure plate 5 is used to limit the pressure plate 5, so that the pressure plate 5 moves downward, pressing the coil winding at the bottom. When the pressure plate 5 moves downward and abuts against the inclined groove 35, the limiting block 33 is driven to slide toward the inside of the hidden groove 32, and the spring 34 is compressed accordingly. After the pressure plate 5 passes over the limiting block 33, it reaches the set position. At this time, the rebound force of the spring 34 drives the limiting block 33 to slide out of the hidden groove 32 and abut against the top of the pressure plate 5, pressing the top of the pressure plate 5. The part is limited, thereby assisting the screw 4 to ensure that the pressure plate 5 will not move subsequently, reducing the bearing force on the screw 4, and then the first motor 8 drives the turntable 2 to continue to rotate a quarter of a turn and then stop, and the coil winding after constant pressure is completed and the constant pressure shaping mechanism outside it are taken out by the manipulator, and finally, the first motor 8 drives the turntable 2 to continue to rotate a quarter of a turn and then stop, the positioning groove 6 returns to the initial position, that is, the position on the left, and the manipulator continues to place the bottom plate 3 and its accompanying structure into the positioning groove 6 on the left, so as to achieve the effect of automatic constant pressure treatment of the coil winding, without the need to perform constant pressure treatment on the coil winding one by one by manual means; After the coil winding is dried, the coil winding and the constant pressure shaping mechanism outside it can also be placed in the positioning groove on the left side, and the turntable 2 is driven by the first motor 8 to rotate a quarter of a turn and then stop. In this process, the second gear 22 is meshed with the tooth arc 24 to drive the drive shaft 19 to rotate, and the second bevel gear 21 is meshed with the four first bevel gears 20 respectively to drive the four transmission shafts 15 to rotate synchronously, and the four reciprocating screws 17 rotate synchronously therewith, thereby driving each limit bar 16 to move from the end of the reciprocating screw 17 close to the screw 4 to the end away from the screw 4, that is, with The four limit bars 16 are moved away from each other, thereby releasing the limit on the coil winding, and the limit block 33 is also away from the top of the pressure plate 5. When the first gear 13 rotates to engage with the toothed disc 27, the toothed disc 27 is driven to reverse by controlling the second motor 26. The toothed disc 27 is engaged with the first gear 13 to drive the extension column 12 to rotate, and then the screw 4 is driven to rotate, and the pressure plate 5 is driven to move upward to disengage from the screw, and then the turntable 2 is driven to rotate a quarter of a turn and then stop. The pressure plate 5, the coil winding and the bottom plate 3 are removed in turn by the robot, and the disassembly of the coil winding is completed, achieving the effect of one machine with two uses.
