Description

Technical Field

[0001] The invention relates to the technical field of motor production, in particular to stator assembly equipment for a motor. Background Art

[0002] With the popularization of new energy vehicles, the demand for motors has increased year by year. In the production process of the motor, the motor stator needs to be installed into the motor housing. In the common stator installation process, manual operation is required, and the work efficiency of manual operation is low. The prior art discloses a stator assembly device for a dual motor of a new energy vehicle, which is used to solve the problems of high labor intensity, high difficulty, easy scalding and scratching of hands by high-temperature casing, and difficulty in controlling the quality of stator sleeved into the casing in the existing stator assembly equipment using manual method, and the problem of stator not being sleeved in place easily occurs; the invention places the casing on a tray, flows to the station through a conveyor line, and the heating jacking mechanism lifts the tray, while driving the heating coil and the power generation heating coil into the inner side of the casing; the casing clamping mechanism first presses the casing, and after the casing is lifted into place, the clamping mechanism lifts and presses the casing through the second cylinder, and a pilot valve is arranged on the lower side of the second cylinder to prevent the mechanism from falling due to sudden gas failure; the invention can quickly and accurately heat to the set temperature, ensure the temperature is accurate, and does not require personnel to contact the high-temperature casing, automatically press and install, ensure the stator is in place in the casing, control the assembly quality, and reduce labor intensity.

[0003] However, the patent requires the stator to be positioned and clamped into the motor housing during the processing. Since a large amount of copper wire is wrapped on the stator, the copper wire on the stator will be warped when the stator is positioned and clamped by the clamping device and the positioning device, which will cause the stator to be stuck between the copper wire and the inner wall of the motor housing during the installation process, causing blockage and making it impossible to install. For this reason, an improved technology on the market proposes a stator assembly device for a new energy vehicle dual motor, including a mounting table, a transmission mechanism, a first mechanical arm at the side end of the transmission mechanism for loading the motor housing, and a mechanical arm for loading the motor stator. The invention relates to a stator feeding mechanism, a pressing assembly mechanism for installing the motor stator into the motor housing, and a unloading mechanism for unloading the motor housing after installation. The stator feeding mechanism includes a feeding rack, a second mechanical arm, a feeding assembly, a stator clamping claw, a first telescopic cylinder and a second telescopic cylinder. The feeding rack is located at the side end of the transmission mechanism, the feeding assembly and the first telescopic cylinder are both arranged on the feeding rack, the second telescopic cylinder is arranged at the output end of the first telescopic cylinder, the stator clamping claw is arranged at the output end of the second telescopic cylinder, and the second mechanical arm is arranged on the mounting table and is located at the side end of the feeding assembly.

[0004] However, when the above improved technology is used for stator feeding, the structure is too complex. In the first step, the second robotic arm is used to clamp the motor stator from the conveyor belt and place it on the feeding sliding plate. Then, the feeding motor is started to drive the feeding drive rod to rotate. The gear on the feeding drive rod and the rack on the feeding sliding plate cooperate with each other to drive the feeding sliding plate to move towards the direction of the stator clamping claw, so as to convey the motor stator to directly below the stator clamping claw. Then, the second telescopic cylinder is started, and the stator clamping claw is driven by the second telescopic cylinder to move downward to the inner wall of the motor stator. Then, the clamping motor is started, and the clamping worm is driven by the clamping motor to rotate. The clamping worm and the rack on the clamping sliding sleeve cooperate with each other to drive the clamping sliding sleeve to slide downward. While the clamping sliding sleeve slides downward, it drives the connecting block hinged to it to push several clamping contact plates outwards and tightly contact the inner wall of the motor stator, so as to realize the clamping and positioning of the motor stator.

[0005] During the above clamping and feeding process, a set of robotic arms, two sets of motors, a set of cylinders and multiple transmission components are required. The structure is too complex. The more power units there are, the higher the energy consumption and the failure rate, which is not conducive to smooth production. Moreover, after the sliding plate sends the stator to the clamping claw and returns, there is hard friction between the lower wall of the stator and the lower wall of the sliding plate, which will inevitably cause wear of the stator or the sliding plate, and then affect the product quality. In summary, it is necessary to optimize and improve the stator assembly equipment of the motor. Summary of the Invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Example:

[0032] like Figures 1 to 6 As shown, an embodiment of the present invention provides a stator assembly device for a motor, comprising a stator body, a rotating worktable 1, a column 2, a mechanical arm 4, an assembly station 3 and a feeding conveyor belt, wherein the assembly station 3 is fixedly connected to the upper wall of the rotating worktable 1, an assembly cavity 301 penetrating the upper wall of the assembly station 3 is provided inside the assembly station 3, and a positioning base 302 is fixedly connected to the lower wall inside the assembly cavity 301. In this embodiment, the rotating worktable 1 has the same structure and function as the prior art, and is used for the assembly operation of the motor housing and the stator body;

[0033] In order to improve the smoothness of the extension and retraction actions of the extension shaft of the air cylinder 8, the robotic arm 4 is arranged at the upper end of the column 2. An extension arm 5 is arranged at one end of the robotic arm 4 away from the column 2. A connecting plate 6 is slidably connected to the lower wall of the extension arm 5 through a guiding structure. The guiding structure includes two groups of guiding rods 7. Both groups of guiding rods 7 are fixedly connected to the upper wall of the connecting plate 6. One end of both groups of guiding rods 7 away from the connecting plate 6 penetrates through the extension arm 5 and is slidably connected thereto. Through the guiding action of the two groups of guiding rods 7, the smoothness of the extension and retraction actions of the extension shaft of the air cylinder 8 can be effectively improved;

[0034] In order to drive the transfer of the stator body and realize the clamping action, a lifting drive structure for driving the lifting of the connecting plate 6 is arranged between the connecting plate 6 and the extension arm 5. The lifting drive structure is an air cylinder 8. The air cylinder 8 is fixedly connected to the upper wall of the extension arm 5. The extension shaft of the air cylinder 8 penetrates through the inner wall of the extension arm 5 and extends below the extension arm 5. The end of the extension shaft of the air cylinder 8 is fixedly connected to the upper wall of the connecting plate 6. The connecting plate 6 drives the descent and ascent through the extension and retraction actions of the extension shaft of the air cylinder 8. The air cylinder 8 is used to drive the clamping assembly to support and clamp the stator body from the inner cavity of the stator body, and is also used to drive the stator body to lift to realize the feeding operation;

[0035] In order to support and clamp the stator body, a first square rod 9 is fixedly connected to the lower wall of the connecting plate 6. One end of the first square rod 9 far from the connecting plate 6 is fixedly connected to a fixed sleeve 23. A positioning plate 19 is slidably connected to the outer wall of the first square rod 9 and above the fixed sleeve 23. A protective cover 10 is fixedly connected to the upper wall of the positioning plate 19. A clamping assembly for expanding and clamping the stator body from the internal gap of the stator body is arranged between the positioning plate 19 and the fixed sleeve 23. The clamping assembly includes four groups of support seats 22. The four groups of support seats 22 are all slidably connected to the lower wall of the positioning plate 19 and are respectively located in the front, back, left and right of the fixed sleeve 23. A linkage structure for driving the support seats 22 to translate and slide when the fixed sleeve 23 moves up and down is arranged between the support seats 22 and the fixed sleeve 23. A support plate 25 is fixedly connected to one side of the support seat 22 far from the fixed sleeve 23. A buffer layer 26 is fixedly connected to one side of the support plate 25 far from the support seat 22. The linkage structure includes multiple groups of support arms 24. The multiple groups of support arms 24 are rotatably connected in sequence between the support seats 22 and the fixed sleeve 23 in a vertical distribution. The buffer layer 26 is a rubber pad. Four groups of chutes 20 are arranged on the lower wall of the positioning plate 19. The four groups of chutes 20 are all circumferentially equally distributed with the center of the positioning plate 19 as the center, and the length directions of the four groups of chutes 20 are all perpendicular to the center of the positioning plate 19. A slider 21 is slidably connected to the inner side wall of the chute 20. The support seat 22 is fixedly connected to the lower wall of the slider 21. The support seat 22 is slidably connected to the positioning plate 19 through the slider 21 and the chute 20. The buffer layer 26 made of rubber pad can play a buffering role during clamping and also play a certain anti-slip role. When the positioning plate 19 contacts the upper wall of the stator body, the extending shaft of the cylinder 8 continues to extend, driving the fixed sleeve 23 to continue to move down. Since the support seat 22 and the positioning plate 19 are slidably connected, the support seat 22 will no longer move down after the positioning plate 19 stops moving down. When the fixed sleeve 23 moves down, it will push the support seat 22 in the direction away from the fixed sleeve 23 through multiple groups of support arms 24. When the four groups of support arms 24 are pushed simultaneously, an expanding action is formed, so as to realize the expanding and clamping action on the stator body from the inner cavity of the stator body;

[0036] In order to control the supporting force during expanding and clamping, a pressure detection structure for detecting the supporting pressure is arranged on the inner wall of the buffer layer 26. The pressure detection structure is a pressure sensor 27. The pressure sensor 27 is fixedly connected to one side of the support plate 25 far from the support seat 22. The pressure sensor 27 penetrates the inner wall of the buffer layer 26. The supporting force can be detected through the pressure sensor 27, and the supporting force is controlled by controlling the extending length of the extending shaft of the cylinder 8, and the supporting force is maintained within a range that can both meet the clamping requirement and not cause deformation of the stator body;

[0037] In order to realize the action of the clamping assembly driving the stator body to be transferred to the assembly cavity 301 and then releasing the stator body, a stripping structure for releasing the clamping assembly after the stator body is placed in place is arranged between the upper part of the positioning plate 19 and the assembly station 3. The stripping structure includes a setscrew 11, a first spring 12, a spring pin 13, a pressing plate 14, a second square rod 16 and a second spring 18. The setscrew 11, the first spring 12 and the spring pin 13 are sequentially arranged on the inner wall of the assembly station 3 from outside to inside and close to the upper wall of the assembly station 3. One end of the spring pin 13 away from the first spring 12 penetrates the inner wall of the assembly station 3 and extends into the interior of the assembly cavity 301. An arc angle is arranged at the connection between the end of the spring pin 13 extending into the interior of the assembly cavity 301 and the upper wall of the spring pin 13. The pressing plate 14 is fixedly connected to the outer wall of the first square rod 9 and is located inside the protective cover 10. A conical surface 1401 is arranged on the circumferential outer wall of the pressing plate 14. A sliding seat 15 is fixedly connected between the upper wall of the positioning plate 19 and the circumferential side wall of the positioning plate 19 and between the first square rod 9. The second square rod 16 is slidably connected through the inner wall of the sliding seat 15. The length direction of the second square rod 16 is perpendicular to the central extension line of the positioning plate 19. One end of the second square rod 16 facing the center of the positioning plate 19 is fixedly connected with a wedge block 17. An inclined surface adapted to the taper of the conical surface 1401 on the outer wall of the pressing plate 14 is arranged on one side of the wedge block 17 away from the second square rod 16. The second spring 18 is sleeved on the outer wall of the second square rod 16 and is located between the wedge block 17 and the sliding seat 15. An arc angle is arranged at the connection between the end of the second square rod 16 away from the wedge block 17 and the lower wall of the second square rod 16. When the extending shaft of the air cylinder 8 moves downward to drive the clamping assembly to clamp the stator body, the pressing plate 14 moves downward synchronously. Through the cooperation of its conical surface 1401 and the wedge block 17, the second square rod 16 is pushed out to the side away from the center of the positioning plate 19. When the stator body is moved into the assembly cavity 301, during the downward movement of the second square rod 16, through the cooperation of the arc angle on its own and the arc angle on the spring pin 13, the spring pin 13 is squeezed and moved. When the stator body is placed above the positioning base 302, the second square rod 16 just moves below the spring pin 13. The spring pin 13 is elastically reset by the first spring 12 and catches the second square rod 16 from above the second square rod 16. At this time, the extending shaft of the air cylinder 8 retracts. Since the positioning plate 19 and the second square rod 16 are caught by the spring pin 13 and cannot rise synchronously with the air cylinder 8, the retracting action of the extending shaft of the air cylinder 8 drives the support arm 24 to rotate through the fixed sleeve 23, and drives a plurality of support seats 22 to move towards the direction close to the fixed sleeve 23 through the support arm 24, thereby completing the release of the clamping state of the stator body. When the extending shaft of the air cylinder 8 retracts to a certain stroke, the pressing plate 14 disengages from the pressing of the wedge block 17, and the second spring 18 pushes the second square rod 16 to reset. At this time, the spring pin 13 no longer restricts the second square rod 16, and the positioning plate 19 can rise synchronously with the extending shaft of the air cylinder 8 to complete the transfer work of the stator body.

[0038] Working principle: In this embodiment, the rotary table 1 has the same structure and usage function as the prior art and is used for the assembly operation of the motor housing and the stator body. Through the guiding action of the two groups of guiding rods 7, the smoothness of the extending and retracting actions of the extending shaft of the cylinder 8 can be effectively improved. The cylinder 8 is used to drive the clamping assembly to support and clamp the stator body from the inner cavity of the stator body, and is also used to drive the stator body to lift to achieve the feeding operation. The buffer layer 26 made of rubber pads can play a buffering role during clamping and also has a certain anti-slip effect. When the positioning plate 19 contacts the upper wall of the stator body, the extending shaft of the cylinder 8 continues to extend, driving the fixed sleeve 23 to continue to move downward. Since the support seat 22 is slidably connected to the positioning plate 19, when the positioning plate 19 stops moving downward, the support seat 22 also stops moving downward. When the fixed sleeve 23 moves downward, it will push the support seat 22 away from the fixed sleeve 23 through multiple groups of support arms 24. When the four groups of support arms 24 are pushed simultaneously, an expanding action is formed, thereby realizing the expanding and clamping action on the stator body from the inner cavity of the stator body. The support force can be detected through the pressure sensor 27, and the support force is controlled by controlling the extending length of the extending shaft of the cylinder 8. The support force is maintained within a range that can meet the clamping requirement without causing deformation of the stator body. When the extending shaft of the cylinder 8 moves downward to drive the clamping assembly to clamp the stator body, the pressing plate 14 moves downward synchronously. Through the cooperation of its conical surface 1401 and the wedge block 17, the second square rod 16 is pushed out to the side away from the center of the positioning plate 19. When the stator body is moved into the assembly cavity 301, during the downward movement of the second square rod 16, the arc angle of the second square rod 16 cooperates with the arc angle on the spring pin 13 to squeeze and move the spring pin 13. When the stator body is placed above the positioning base 302, the second square rod 16 just moves below the spring pin 13. The spring pin 13 is elastically reset by the first spring 12 and catches the second square rod 16 from above. At this time, the extending shaft of the cylinder 8 retracts. Since the positioning plate 19 and the second square rod 16 are caught by the spring pin 13 and cannot rise synchronously with the cylinder 8, the retracting action of the extending shaft of the cylinder 8 drives the support arm 24 to rotate through the fixed sleeve 23, and drives multiple groups of support seats 22 to move towards the direction close to the fixed sleeve 23 through the support arm 24, thereby completing the release of the clamping state of the stator body. When the extending shaft of the cylinder 8 retracts to a certain stroke, the pressing plate 14 disengages from the pressing of the wedge block 17, and the second spring 18 pushes the second square rod 16 to reset. At this time, the spring pin 13 no longer restricts the second square rod 16, and the positioning plate 19 can rise synchronously with the extending shaft of the cylinder 8 to complete the transfer work of the stator body.
