Description

Technical Field

[0001] The utility model relates to the technical field of motor production, in particular to a rotor bagging baking heat shrink film machine. Background Art

[0002] A motor is an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. A motor usually consists of a stator and a rotor. The stator coils of some motors are usually processed by injection molding. In this case, it is necessary to coat a film on the outside of the stator coils of the motor to protect the stator coils and prevent the injection molding material from entering the inside of the coils.

[0003] Currently, when coating a film on the stator coils of a motor, it is necessary for workers to manually tear the cut heat shrink film, then put the heat shrink film loop on the outer circle of the motor rotor coil, and then heat it at a high temperature to make the film shrink and fix on the rotor surface. Manual film tearing is inconvenient, and the diameter of the torn film is only slightly larger than that of the rotor coil, which makes it difficult for workers to operate and the film coating speed is slow. Content of the Utility Model

[0004] In order to solve the above problems, the utility model provides a rotor bagging baking heat shrink film machine.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions: A rotor bagging baking heat shrink film machine includes a frame and a substrate arranged on the top of the frame. A bearing seat is arranged on the substrate, and a turntable is rotatably arranged on the bearing seat. An installation frame is also arranged on the substrate. A film cutting machine and an installation rod for installing a film roll are arranged on the installation frame. The characteristics are as follows: Four placing seats are circumferentially and spacedly arranged on the turntable. A film tearing assembly for opening the cut film loop is arranged at the discharge port of the film cutting machine on the installation frame. A moving assembly is also arranged on the substrate beside the installation frame. A film coating assembly is arranged on the moving assembly. The film coating assembly includes a connecting seat. A fixed disk is arranged on the connecting seat. A concentrically arranged rotating shaft is rotatably arranged on the fixed disk. A rotating disk is arranged at one end of the rotating shaft away from the connecting seat. The diameter of the rotating disk is smaller than that of the fixed disk. A plurality of arc-shaped grooves are circumferentially and spacedly arranged on the rotating disk. One end of the arc-shaped groove is close to the edge of the rotating disk, and the other end is close to the center of the rotating disk. Corresponding to the number of arc-shaped grooves, rotating shafts are arranged on the fixed disk near the outer edge of the fixed disk. One end of the rotating shaft is provided with a rocker. The rocker is located on the side of the rotating disk away from the fixed disk. A gripper needle extending away from the rotating disk is arranged at one end of the rocker away from the rotating shaft. The length direction of the gripper needle is the same as the length direction of the rotating shaft. A sliding column is slidably arranged in the arc-shaped groove. One end of the sliding column is connected to the middle part of the top surface of the rocker. A driving unit for driving the rotating shaft to rotate is also arranged on the fixed disk. A heat shrinkage assembly is arranged on the substrate beside the turntable.

[0006] By adopting the above technical solution, a substrate, a turntable, a film cutting machine, a placement seat, a film tearing assembly, a moving assembly, a fixed disk, gripper needles, a driving unit, and a film shrinking assembly are provided. First, the rotor is placed on the placement seat, and then the turntable is rotated to rotate the placement seat to the film mounting position. The film cut by the film cutting machine falls on the film tearing assembly. The film tearing assembly opens the film loop into a circular ring-like shape. The moving assembly is used to drive the film sleeving assembly to move to the film loop, and all the gripper needles extend into the film loop. Then, the driving unit is used to drive the rotating disk to rotate. Since one end of the rocker is connected to the fixed disk through a rotating shaft, when the rotating disk rotates, the sliding column slides in the arc-shaped groove, so that the rocker rotates around the rotating shaft, and further the gripper needles move away from the center of the rotating disk, so that several gripper needles completely support the film loop, making the film loop close to a circle. Then, the moving assembly is used to move the fixed disk so that the film loop is directly above the film mounting position. Subsequently, the moving assembly drives the fixed disk to descend to sleave the film loop on the rotor. Then, the driving unit drives the rotating shaft to rotate, so that the gripper needles slightly move towards the center of the rotating disk, separating the film loop from the gripper needles. Then, the moving assembly drives the fixed disk and the gripper needles to rise and reset. Finally, the turntable is rotated to send the rotor with the sleeved film to the film shrinking assembly. The film shrinking assembly heats the film loop, and the film loop shrinks when heated and stably sleaves on the rotor. Compared with manual film sleeving, the film sleeving speed is fast and the work efficiency is high.

[0007] Further, a support column is arranged between the moving mechanism and the turntable on the substrate. An installation seat is arranged on the support column close to the turntable side. A first pneumatic slide is vertically arranged on the installation seat. A wide finger cylinder is horizontally arranged on the slider of the first pneumatic slide. Demolding rods extend towards the turntable direction on the sliders at both ends of the wide finger cylinder. A demolding plate is arranged on the demolding rods. A plurality of demolding teeth are arranged on the adjacent side of the demolding plate.

[0008] By adopting the above technical solution, a support column, an installation seat, a first pneumatic slide, a wide finger cylinder, demolding rods, a demolding plate, and demolding teeth are provided. When the moving assembly drives the fixed disk to descend and sleave the film loop on the rotor, the wide finger cylinder is used to drive the demolding rods, the demolding plate, and the demolding teeth to move inwards to contact the outer surface of the film loop and fix the film loop. Then, the driving unit drives the rotating shaft to rotate, so that the gripper needles slightly move towards the center of the rotating disk, separating the film loop from the gripper needles. Then, the driving unit drives the fixed disk and the gripper needles to reset. Then, the first pneumatic slide is used to drive the wide finger cylinder, the demolding rods, the demolding plate, and the demolding teeth to descend, ensuring that the film loop stably sleaves on the rotor and preventing the film loop from being incompletely separated from the gripper needles and being driven upwards by the gripper needles when they rise and reset.

[0009] Further, the moving component includes a fixed table disposed on the substrate. A first electric slide is horizontally arranged on the fixed table. A fixing plate is arranged on the slide seat of the first electric slide. A second electric slide is horizontally arranged on the fixing plate. The length direction of the second electric slide is perpendicular to the length direction of the first electric slide. A third electric slide is vertically arranged on the slide seat of the second electric slide. A rotary cylinder is arranged on the slide seat of the third electric slide. The turntable of the rotary cylinder is connected to the connecting seat.

[0010] By adopting the above technical solution, the fixed table, the first electric slide, the fixing plate, the second electric slide, the third electric slide and the rotary cylinder are provided. The first electric slide, the second electric slide and the third electric slide work together to enable the rotary cylinder to move in the XZY directions. Through the rotary cylinder, the fixing plate can be switched between the horizontal orientation and the vertical orientation, so as to control the orientation of the gripper needle to complete transporting the film loop from the film tearing component to the rotor at the film loading position.

[0011] Further, the driving unit includes a driven wheel sleeved on the rotating shaft. A driving motor is arranged on the fixed disk. The output shaft of the driving motor passes through the fixing plate and is provided with a driving wheel. The driving wheel meshes with the driven wheel.

[0012] By adopting the above technical solution, the driven wheel, the driving motor and the driving wheel are provided. The driving motor drives the driving wheel to rotate, thereby driving the driven wheel to rotate, and further driving the rotating shaft to rotate.

[0013] Further, the film tearing component includes a fixed seat arranged on the mounting frame. Two support rods are spacedly arranged on the fixed seat. A bearing plate is jointly arranged at the tops of the two support rods. A plurality of air suction holes are formed in the bearing plate. All the plurality of air suction holes are connected to a vacuum generator. The vacuum generator is connected to an air pump. A fixed rod is horizontally arranged above the bearing plate on the mounting frame. A lifting cylinder is vertically arranged on the fixed rod. The piston rod of the lifting cylinder faces downward and is provided with a mounting block. Two suction cups are spacedly arranged at the bottom of the mounting block. The end of the suction cup is connected to the vacuum generator. The vacuum generator is connected to the air pump.

[0014] By adopting the above technical solution, the fixed seat, the support rods, the bearing plate, the air suction holes, the fixed rod, the lifting cylinder, the mounting block and the suction cups are provided. The film loop cut by the film cutting machine falls on the bearing plate. The lifting cylinder drives the suction cups to descend. Subsequently, the air suction holes traction the lower part of the film loop, and the suction cups traction the upper part of the film loop. Then, the lifting cylinder drives the suction cups to ascend, so as to tear the film loop.

[0015] Further, four carrier tubes are circumferentially and spacedly arranged on the turntable. A carrier column is slidably arranged in each carrier tube. The lower end of the carrier column passes through the turntable, and the upper end is located above the carrier tube and is connected to the placement seat. The film shrinking assembly includes a driving cylinder arranged on the substrate. When the rotor on the placement seat undergoes the film shrinking process, the carrier column is concentric with the piston rod of the driving cylinder. A support frame is arranged on the substrate, and a film shrinking box is arranged on the support frame. A circular opening for the rotor to enter the film shrinking box is arranged at the bottom of the film shrinking box. A plurality of electric heating rods are arranged in the film shrinking box.

[0016] By adopting the above technical solution, the carrier tube, carrier column, driving cylinder, film shrinking box, circular opening, and electric heating rods are provided. The turntable is rotated to send the rotor after sleeving the film to the film shrinking process. The driving cylinder is used to push the carrier column upward, so as to push the rotor on the placement seat upward until it passes through the circular opening and reaches the inside of the film shrinking box. The electric heating rods are energized to generate heat, and the film ring is heated and shrunk, and stably sleeved on the rotor.

[0017] To sum up, the present utility model has the following beneficial effects: In this application, a substrate, a turntable, a film cutting machine, a placement seat, a film tearing assembly, a moving assembly, a fixed disk, a gripping needle, a driving unit, and a film shrinking assembly are provided.

The moving assembly is used to drive the film sleeving assembly to move to the film ring, and all the gripping needles extend into the film ring. Then, the driving unit is used to drive the rotating disk to rotate. Since one end of the rocker is connected to the fixed disk through a rotating shaft, when the rotating disk rotates, the sliding column slides in the arc-shaped groove, so that the rocker rotates around the rotating shaft, and further the gripping needles move away from the center of the rotating disk, so that several gripping needles fully support the film ring, making the film ring close to a circular shape. Then, the moving assembly is used to move the fixed disk, so that the film ring is located directly above the film sleeving position. Subsequently, the moving assembly drives the fixed disk to descend to sleeve the film ring on the rotor. Then, the driving unit drives the rotating shaft to rotate, so that the gripping needles slightly move towards the center of the rotating disk, making the film ring separate from the gripping needles. Then, the moving assembly drives the fixed disk and the gripping needles to rise and reset. Finally, the turntable is rotated to send the rotor after sleeving the film to the film shrinking assembly. The film shrinking assembly heats the film ring, and the film ring is heated and shrunk, and stably sleeved on the rotor. Compared with manual film sleeving, the film sleeving speed is fast and the working efficiency is high. BRIEF DESCRIPTION OF THE DRAWINGS

A turntable 20 is rotatably arranged on the bearing seat 12, so that the turntable 20 can rotate. The mounting frame 30 is arranged on the base plate 11, and a film cutting machine 31 and a mounting rod 32 for mounting a film roll are arranged on the mounting frame 30. The film cutting machine 31 pulls and cuts the film of the film roll into a film loop. Four placing seats 21 are circumferentially arranged at intervals on the turntable 20 for placing rotors. The film tearing assembly 40 is arranged on the mounting frame 30 at the discharge port of the film cutting machine 31 for opening the cut film loop. The moving assembly 50 is arranged on the base plate 11 beside the mounting frame 30, and the film sleeving assembly 60 is arranged on the moving assembly 50. A heat shrinking assembly 80 is also arranged on the base plate 11 on one side of the turntable 20. The moving assembly 50 drives the film sleeving assembly 60 to sleeve the film loop on the tearing assembly 40 onto the rotor. The heat shrinking assembly 80 heats the film loop, and the film loop shrinks when heated and is stably sleeved on the rotor.

[0029] Specifically, the moving assembly 50 includes a fixed table 51 arranged on the base plate 11. A first electric slide table 52 is horizontally arranged on the fixed table 51. A fixing plate 53 is arranged on the slide seat of the first electric slide table 52. A second electric slide table 54 is horizontally arranged on the fixing plate 53, so that the first electric slide table 52 can drive the second electric slide table 54 to move. The length direction of the second electric slide table 54 is perpendicular to the length direction of the first electric slide table 52. A third electric slide table 55 is vertically arranged on the slide seat of the second electric slide table 54, so that the second electric slide table 54 can drive the third electric slide table 55 to move. A rotary cylinder 56 is arranged on the slide seat of the third electric slide table 55. The film sleeving assembly 60 includes a connecting seat 61. The turntable of the rotary cylinder 56 is connected to the connecting seat 61. The first electric slide table 52, the second electric slide table 54, and the third electric slide table 55 act together to enable the rotary cylinder 56 to move in the XZY directions, and the fixing plate 53 can be switched between the horizontal orientation and the vertical orientation through the rotary cylinder 56.

[0030] The membrane sleeve assembly 60 further includes a fixed disk 62 disposed on the connecting seat 61. A concentrically arranged rotating shaft 63 is rotatably provided on the fixed disk 62. A rotating disk 64 is provided at one end of the rotating shaft 63 away from the connecting seat 61, such that the rotating disk 64 rotates relative to the fixed disk 62. The diameter of the rotating disk 64 is smaller than that of the fixed disk 62. A plurality of arc-shaped grooves 65 are circumferentially spaced on the rotating disk 64. One end of each arc-shaped groove 65 is adjacent to the edge of the rotating disk 64, and the other end is adjacent to the center of the rotating disk 64. Corresponding to the number of the arc-shaped grooves 65, rotating shafts 66 are provided on the fixed disk 62 near the outer edge of the fixed disk 62. A rocker 67 is provided at one end of each rotating shaft 66. The rocker 67 is located on the side of the rotating disk 64 away from the fixed disk 62, such that the rocker 67 can rotate around the rotating shaft 66. A gripper needle 68 extending away from the rotating disk 64 is provided at one end of the rocker 67 away from the rotating shaft 66. The length direction of the gripper needle 68 is the same as that of the rotating shaft 66. A sliding column is slidably provided in the arc-shaped groove 65. One end of the sliding column is connected to the middle of the top surface of the rocker 67. A driving unit 70 for driving the rotation of the rotating shaft 63 is further provided on the fixed disk 62. First, place the rotor on the placing seat 21, then rotate the turntable 20 to rotate the placing seat 21 to the film mounting position. The film cut by the film cutting machine 31 falls on the film tearing assembly 40. The film tearing assembly 40 opens the film loop into a similar circular ring shape. Use the moving assembly 50 to drive the membrane sleeve assembly 60 to move to the position of the film loop, and all the gripper needles 68 extend into the film loop. Then, drive the rotating disk 64 to rotate through the driving unit 70. Since one end of the rocker 67 is connected to the fixed disk 62 through the rotating shaft 66, when the rotating disk 64 rotates, the sliding column slides in the arc-shaped groove 65, so that the rocker 67 rotates around the rotating shaft 63, and further the gripper needle 68 moves away from the center of the rotating disk 64, so that a plurality of gripper needles 68 fully support the film loop, making the film loop close to a circular shape. Then, use the moving assembly 50 to move the fixed disk 62, so that the film loop is directly above the film mounting position. Subsequently, the moving assembly 50 drives the fixed disk 62 to descend to put the film loop on the rotor. Subsequently, the driving unit 70 drives the rotating shaft 63 to rotate, making the gripper needle 68 slightly move towards the center of the rotating disk 64, so that the film loop is separated from the gripper needle 68. Then, drive through the moving assembly 50, and the gripper needle 68 on the fixed disk 62 rises and resets.

[0031] The driving unit 70 includes a driven wheel 71 sleeved on the rotating shaft 63. A driving motor 72 is provided on the fixed disk 62. The output shaft of the driving motor 72 passes through the fixing plate 53 and is provided with a driving wheel 73. The driving wheel 73 meshes with the driven wheel 71. By driving the driving wheel 73 to rotate through the driving motor 72, the driven wheel 71 is driven to rotate, and further the rotating shaft 63 is driven to rotate.

[0032] When setting up, a support column 90 is arranged between the moving mechanism and the turntable 20 on the substrate 11. An installation seat 91 is arranged on the support column 90 near the turntable 20. A first pneumatic slide table 92 is vertically arranged on the installation seat 91. A wide finger cylinder 93 is horizontally arranged on the slider of the first pneumatic slide table 92, so that the first pneumatic slide table 92 can drive the wide finger cylinder 93 to lift. Demolding rods 94 extend towards the turntable 20 on the sliders at both ends of the wide finger cylinder 93. A demolding plate 95 is arranged on the demolding rods 94. A number of demolding teeth 96 are arranged on one adjacent side of the demolding plate 95. When the moving assembly 50 drives the fixed plate 62 to descend and the film ring is sleeved on the rotor, the wide finger cylinder 93 drives the demolding rods 94, the demolding plate 95, and the demolding teeth 96 to move inwards, contact with the outer surface of the film ring, and fix the film ring. Subsequently, the driving unit 70 drives the rotating shaft 63 to rotate, so that the gripper needle 68 slightly moves towards the center of the rotating disk 64, causing the film ring to separate from the gripper needle 68. Then, the driving unit 70 drives the fixed plate 62 and the gripper needle 68 to reset. Then, the first pneumatic slide table 92 is used to drive the wide finger cylinder 93, the demolding rods 94, the demolding plate 95, and the demolding teeth 96 to descend, ensuring that the film ring is stably sleeved on the rotor and preventing the film ring from being incompletely separated from the gripper needle 68 and being driven upwards by the gripper needle 68 when it rises and resets.

[0033] The film tearing assembly 40 includes a fixed seat 41 arranged on the mounting frame 30. Two support rods 42 are spacedly arranged on the fixed seat 41. A bearing plate 43 is jointly arranged at the tops of the two support rods 42. A number of air suction holes 44 are formed on the bearing plate 43. All the air suction holes 44 are connected to a vacuum generator, and the vacuum generator is connected to an air pump. After the film ring falls on the bearing plate 43, when the air pump is started, the lower part of the film ring can be pulled. A fixed rod 45 is horizontally arranged above the bearing plate 43 on the mounting frame 30. A lifting cylinder 46 is vertically arranged on the fixed rod 45. The piston rod of the lifting cylinder 46 extends downwards and is provided with a mounting block 47. Two suction cups 48 are spacedly arranged at the bottom of the mounting block 47. The end of the suction cup 48 is connected to the vacuum generator, and the vacuum generator is connected to the air pump. The lifting cylinder 46 drives the suction cups 48 to descend. Subsequently, the air suction holes 44 pull the lower part of the film ring, and the suction cups 48 pull the upper part of the film ring. Then, the lifting cylinder 46 drives the suction cups 48 to rise, thereby tearing the film ring.

[0034] During specific settings, four bearing tubes 22 are circumferentially and spacedly arranged on the turntable 20. A bearing column 23 is slidably arranged in the bearing tube 22. The lower end of the bearing column 23 passes through the turntable 20, and the upper end is located above the bearing tube 22 and connected to the placing seat 21, so that the bearing column 23 and the placing seat 21 can slide synchronously. The film shrinking assembly 80 includes a driving cylinder 81 arranged on the substrate 11. When the rotor on the placing seat 21 undergoes the film shrinking process, the bearing column 23 is concentric with the piston rod of the driving cylinder 81, so that the driving cylinder 81 can drive the bearing column 23 to rise. A support frame 82 is arranged on the substrate 11, and a film shrinking box 83 is arranged on the support frame 82. A circular opening 84 for the rotor to enter the film shrinking box 83 is arranged at the bottom of the film shrinking box 83. A plurality of electric heating rods 85 are arranged in the film shrinking box 83. The turntable 20 is rotated to send the rotor after being sleeved with the film to the film shrinking process position. The driving cylinder 81 is used to push the bearing column 23 to rise, thereby pushing the rotor on the placing seat 21 upward until it passes through the circular opening 84 and reaches the inside of the film shrinking box 83. The electric heating rods 85 are energized to generate heat, and the film ring is heated and shrunk, and stably sleeved on the rotor.

[0035] The operating principle of a rotor bagging and heat shrinking film machine in the present embodiment is: first place the rotor on the placement seat 21, then rotate the turntable 20, rotate the placement seat 21 to the film placement position, and the film cut by the film cutting machine 31 falls on the supporting plate 43, and the lifting cylinder 46 drives the suction cup 48 to descend, and start the air pump, so that the suction hole 44 pulls the lower part of the film circle, and the suction cup 48 pulls the upper part of the film circle, and then the suction cup 48 is driven to rise by the lifting cylinder 46, so as to tear the film circle. Then, the first electric slide 52, the second electric slide 54, the third electric slide 55, and the rotating cylinder 56 work together to make the gripper needle 68 in a horizontal state and all of them are located in the film ring. The driving cylinder 81 is started to drive the active wheel 73 to rotate, thereby driving the driven wheel 71, the rotating shaft 63, and the rotating disk 64 to rotate, so that the sliding column slides in the arc groove 65, so that the rocker 67 rotates around the rotating shaft 63, and then the gripper needle 68 moves away from the center of the rotating disk 64, so that the film ring is completely propped up by a number of gripper needles 68, so that the film ring is close to a circle, and then the first electric slide 52, the second electric slide 54, the third electric slide 55, and the rotating cylinder 56 are used to move the fixed disk 62, so that the film ring is located directly above the film loading position, and then the third electric slide 55 drives the rotating cylinder 56 and the fixed disk 62 to descend, and the film ring is put on the rotor. Then start the broad finger cylinder 93 to drive the film stripping rod 94, the film stripping plate 95, and the film stripping teeth 96 to move inward, contact the outer surface of the film ring, and fix the film ring. Then drive the motor 72 to drive the rotating shaft 63 to rotate, so that the gripper needle 68 moves slightly toward the center of the rotating disk 64, so that the film ring and the gripper needle 68 are separated. Then start the first pneumatic slide 92 to drive the broad finger cylinder 93, the film stripping rod 94, the film stripping plate 95, and the film stripping teeth 96 to descend, ensuring that the film ring is stably sleeved on the rotor, and then the fixed disk 62 and the gripper needle 68 are reset. Turn the turntable 20 again to send the rotor after filming to the shrink film assembly 80, start the drive cylinder 81 to push the bearing column 23 up, so as to push the rotor on the placement seat 21 upward until it passes through the circular opening 84 and reaches the inside of the shrink film box 83. The electric heating rod 85 is energized to generate heat, and the film ring shrinks due to the heat and is stably sleeved on the rotor.
