Description

Technical Field

[0001] This utility model relates to the technical field of insulating paper forming equipment, and in particular to a stator insulating paper forming and inserting mechanism. Background Technology

[0002] In the motor manufacturing process, the stator is a core component. Insulating paper needs to be inserted into its slots to achieve electrical insulation between the windings and the iron core, ensuring the safety and stability of motor operation. Therefore, the insertion of stator insulating paper is one of the key processes in motor assembly.

[0003] In the early days, the insertion of stator insulation paper relied heavily on manual operation. Operators had to manually shape the insulation paper and then insert it into the stator slots one by one. This method was not only labor-intensive and inefficient, but also prone to errors in manual operation, which could lead to misalignment, wrinkling, or even damage of the insulation paper, directly affecting the insulation performance of the stator and the overall quality of the motor, making it difficult to meet the needs of large-scale motor production.

[0004] To address the drawbacks of manual operation, automated stator insulation paper forming and insertion equipment has gradually emerged in the industry. This equipment uses mechanical structures to replace manual labor in the forming and insertion of insulation paper, improving production efficiency and insertion consistency to some extent. However, existing automated equipment still has shortcomings in its structural design. The coordination between its forming and insertion mechanisms is not precise enough, especially after the insulation paper is formed. The components used to clamp and transfer the insulation paper have low movement positioning accuracy and lack a stable stroke control mechanism. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a stator insulation paper forming and inserting mechanism, which enables precise clamping, stable transfer, and accurate insertion of the insulation paper after forming, thereby improving stator assembly quality and production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A stator insulation paper forming and inserting mechanism includes an insulation paper forming device. The insulation paper forming device is provided with a structure for forming insulation paper. The insulation paper forming device is also provided with an inserting component and a driving component. The inserting component and the driving component are both configured to correspond to the insulation paper forming structure. The inserting component is used to clamp the formed insulation paper. The driving component is used to drive the inserting component to move so as to insert the insulation paper into the stator slot. The inserting component is movably connected to the insulation paper forming device. The driving component is connected to the inserting component.

[0007] Preferably, the paper insert includes a movable plate, which is connected to the insulating paper forming equipment via a slide rail assembly. The insulating paper forming equipment is provided with a mounting plate, and the slide rail assembly is fixed on the mounting plate. The slide rail assembly enables the movable plate to move smoothly, and the mounting plate strengthens the fixation of the slide rail, improves the stability of the paper insert movement, avoids deviation, and ensures accurate insertion of the insulating paper.

[0008] Preferably, a fixing plate is fixed on the movable plate, and a clamping device is fixed on the fixing plate. The fixing plate provides a stable installation base for the clamping device, prevents the clamping device from loosening, ensures stable force when clamping the insulating paper, and avoids the insulating paper from falling off.

[0009] Preferably, the movable plate has a through hole, and part of the structure of the clamping device is located in the through hole. The through hole provides clearance for the movement of the clamping claws, avoids interference between the claws and the movable plate when the claws open and close, and ensures smooth clamping action.

[0010] Preferably, the structure for forming insulating paper includes a forming plate with an insertion hole. Each of the two grippers of the clamping device has a clamping block with a clamping end that can pass through the insertion hole. The forming plate forms the insulating paper, and the clamping end passes through the insertion hole to accurately clamp the insulating paper, ensuring that the insulating paper can be stably gripped after forming and avoiding misalignment.

[0011] Preferably, a connecting plate is fixed to the side of the movable plate away from the fixed plate. The connecting plate is connected to the driving component and serves as a transmission bridge between the driving component and the movable plate, thereby achieving stable power transmission from the driving component and ensuring that the movable plate moves synchronously with the driving component.

[0012] Preferably, the driving component includes a power unit and a ball screw. The output shaft of the power unit is connected to one end of the ball screw. The ball screw is provided with a mounting frame plate and a mounting shaft seat. The mounting frame plate is located close to the power unit, and the mounting shaft seat is located away from the power unit. The ball screw is rotatably connected to both the mounting frame plate and the mounting shaft seat. The mounting frame plate and the mounting shaft seat are both fixed on the insulating paper forming equipment. The ball screw achieves high-precision transmission, and the mounting frame plate and the shaft seat fix the ball screw, improving the movement accuracy of the driving component, avoiding transmission wobbling, and ensuring smooth transfer of the insulating paper.

[0013] Preferably, the ball screw is provided with a ball nut that mates with it, the insulating paper forming device is provided with a moving hole, the connecting plate passes through the moving hole and is connected to the ball nut, the ball nut converts the rotation of the screw into linear movement, the moving hole provides moving space for the connecting plate, realizing precise linear movement of the paper insert and ensuring that the insulating paper is inserted into the stator slot at a consistent depth.

[0014] Preferably, a trigger plate is fixed on the connecting plate, and a trigger end is provided on the trigger plate. The trigger end works with the first, second and third detection elements to provide feedback on the position of the paper insert, providing a position signal for stroke control and ensuring that the action of the paper insert can be accurately controlled.

[0015] Preferably, the insulating paper forming equipment is provided with a detection element one, a detection element two, and a detection element three on the side near the driving component. The trigger end can trigger the sensing of the detection element one, the detection element two, and the detection element three. The three detection elements are respectively positioned at the origin and the upper and lower limit positions to prevent the paper insert from overtraveling and damaging the equipment, ensuring that the reset position is consistent each time the paper is inserted, and improving the safety of operation. The detection element one, the detection element two, and the detection element three can be slot-shaped photoelectric sensors when in use.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention utilizes a sliding rail assembly for the paper inserter that works in conjunction with a mounting plate, and a fixed plate that securely clamps the device. A moving plate with through-holes avoids the grippers, while a clamping block passes through the insertion hole in the forming plate to grip the insulating paper. This design prevents clamping misalignment or interference, significantly improving the stability and accuracy of the insulating paper clamping. Simultaneously, the ball screw of the drive unit rotates in conjunction with the mounting frame plate and mounting shaft, and the ball nut drives the connecting plate to move linearly, preventing transmission wobbling and ensuring smooth paper insertion. This guarantees precise insertion of the insulating paper into the stator slot. Furthermore, the trigger plate, along with detection components one, two, and three, provides stroke control, offering rigid support for the fixed frame structure. Precise assembly of each component reduces gaps, preventing overtravel damage or unexpected displacement. The feeding mechanism is compatible with external paper feeding mechanisms for smooth feeding, eliminating the need for manual intervention during insertion. This effectively improves the device's adaptability, stator assembly quality, and operational reliability. Attached Figure Description

[0024] Example: Please see Figure 1-6A stator insulation paper forming and inserting mechanism includes an insulation paper forming device 1. The insulation paper forming device 1 is provided with a structure for forming insulation paper. The insulation paper forming device 1 is also provided with an inserting component 3 and a driving component 4. The inserting component 3 and the driving component 4 are both arranged in accordance with the insulation paper forming structure. The inserting component 3 is used to clamp the formed insulation paper. The driving component 4 is used to drive the inserting component 3 to move so as to insert the insulation paper into the stator slot. The inserting component 3 is movably connected to the insulation paper forming device 1. The driving component 4 is connected to the inserting component 3. A forming groove and an insertion hole are opened on the forming plate 2. The forming groove is used for forming insulation paper. The insertion hole communicates with the forming groove and allows the clamping end of the clamping block 341 to pass through.

[0025] An installation plate 38 is provided on one side of the insulating paper forming equipment 1. The installation plate 38 is fixedly connected to the insulating paper forming equipment 1. A slide rail assembly 37 is fixedly connected to the installation plate 38. The slide rail assembly 37 is arranged vertically. The moving plate 31 of the paper insert 3 is slidably connected to the slide rail assembly 37 through a slider, so that the moving plate 31 can move vertically back and forth along the slide rail assembly 37. The installation plate 38 is also provided with a drag chain to organize and protect the power and data lines of the paper insert 3, the driving component 4 and the detection component, and to prevent them from being pulled or worn during movement. A fixed plate 33 is fixedly connected to the movable plate 31, and a clamping device 34 is fixedly connected to the fixed plate 33. The clamping device 34 can be a pneumatic gripper when in use. The gripper of the clamping device 34 can open and close in the horizontal direction. A through hole 32 is provided on the movable plate 31 at the position of the gripper of the clamping device 34. The size of the through hole 32 is larger than the maximum opening and closing size of the gripper of the clamping device 34 to avoid interference between the gripper and the movable plate 31 when the gripper moves. A clamping block 341 is fixedly connected to the gripper of the clamping device 34. The clamping end of the clamping block 341 can extend into the molding groove through the insertion hole of the molding plate 2. A connecting plate 35 is fixedly connected to the side of the movable plate 31 away from the fixed plate 33. The insulating paper forming device 1 has a movable hole at the position corresponding to the connecting plate 35. The connecting plate 35 extends through the movable hole into the interior of the insulating paper forming device 1 and is fixedly connected to the ball nut of the driving component 4. The power unit 41 of the drive component 4 is fixedly connected inside the insulating paper forming equipment 1. The output shaft of the power unit 41 is connected to one end of the ball screw 43. The power unit 41 can be a motor when in use. The ball screw 43 is provided with a mounting frame plate 42 and a mounting shaft seat 44. Both the mounting frame plate 42 and the mounting shaft seat 44 are fixedly connected inside the insulating paper forming equipment 1. The ball screw 43 is rotatably connected to the mounting frame plate 42 and the mounting shaft seat 44 to ensure stable rotation of the ball screw 43. A ball nut is sleeved on the ball screw 43. The ball nut is fixedly connected to the connecting plate 35. When the ball screw 43 rotates, it can drive the ball nut and the connecting plate 35 to move vertically. A trigger plate 36 is fixedly connected to the connecting plate 35. The trigger plate 36 is provided with a trigger end 361. Inside the insulating paper forming equipment 1, near the trigger plate 36, there are three detection elements: detection element 5, detection element 6, and detection element 7. All three are fixedly connected to the insulating paper forming equipment 1 and arranged vertically. They serve as detection points for the low limit, origin, and high limit, respectively. Detection element 5, detection element 6, and detection element 7 are all electrically connected to the control system of the equipment. The control system is also electrically connected to the power unit 41 and the clamping device 34 to realize signal feedback and action control. The control system has preset reciprocating stroke parameters based on the origin and receives overtravel signals from detection element 5 and detection element 7 to realize the linkage of precise control and safety protection. In use, the external paper feeding mechanism delivers insulating paper into the forming groove of the forming plate 2. The forming plate 2, in conjunction with the external forming assembly, presses the insulating paper into a shape that fits the stator groove. The lower end of the formed insulating paper extends to the insertion hole. The control system controls the clamping device 34 to start, and the grippers of the clamping device 34 close, causing the clamping end of the clamping block 341 to pass through the insertion hole of the forming plate 2, clamping the formed insulating paper and ensuring that the insulating paper is stably fixed on the clamping block 341. After clamping, the control system controls the power device 41 to start according to the preset stroke parameters, driving the ball screw 43 to rotate. The ball screw 43 drives the ball nut to move upward, which drives the moving plate 31, the clamping device 34, and the insulating paper to move upward synchronously through the connecting plate 35. At this time, the stator is fixed to the forming plate 2 by the external positioning mechanism. Above, the stator slot of the stator is aligned with the upper end of the insulating paper. As the insulating paper moves upward along the set stroke, it is gradually and accurately inserted into the stator slot. When the moving plate 31 reaches the upper stop position preset by the control system, the power unit 41 stops, and the insulating paper is fully inserted into the stator slot. Then, the control system controls the gripper 34 to open and release the insulating paper. The power unit 41 reverses and drives the paper insert 3 to move downward along the set stroke. When the trigger end 361 triggers the second detection element 6 again, the paper insert 3 returns to the origin. The drag chain then retracts and straightens, waiting for the next paper insertion operation to complete one work cycle. If abnormal parameters or origin deviation cause the moving plate 31 to exceed the stroke, and the trigger end 361 triggers the first detection element 5 or the third detection element 7, the control system immediately cuts off the power supply to the power unit 41 and forces the machine to stop to avoid collision damage.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments.
