Description

Technical Field

[0001] This utility model relates to the field of motor assembly technology, and in particular to a stator feeding mechanism. Background Technology

[0002] In the refined production process of motor assembly, the precise assembly of the stator and the rear end cover is a crucial step in ensuring motor performance. To ensure the efficient completion of this process, the stator needs to be accurately transferred from a dedicated material box to the designated workstation on the assembly line before assembly. Due to the complex structure and heavy weight of the stator, traditional manual handling methods suffer from low efficiency and large positioning deviations, which can easily lead to assembly quality problems. Therefore, there is an urgent need to design a professional stator loading mechanism. Utility Model Content

[0003] This utility model solves the problems in related technologies and proposes a stator feeding mechanism. The stator is positioned and lifted by a lifting and positioning component, which facilitates the gripping component to grip it. The gripping component is divided into a stator gripping inner claw for gripping the stator and a lead wire gripper for clamping the lead wire. It can grip the stator and clamp the lead wire at the same time, which facilitates the subsequent assembly with the rear end cover.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a stator feeding mechanism, comprising: Conveyor line; The lifting and positioning assembly is installed below the conveyor line and is used to lift and position the stator upwards. A horizontal push assembly is installed on one side of the conveyor line and is used to push the stator to one side of the conveyor line for repositioning. The gripping component, located at the end of the conveyor line and driven by the XZ linear module, grips the stator.

[0005] As a preferred embodiment, the system also includes a guide assembly installed on the conveyor line. The guide assembly includes a mounting base, a stator coil guide rod, and a stator core guide rod, both of which are mounted on the mounting base.

[0006] As a preferred embodiment, the conveyor line is a belt conveyor, and side guards are provided on both sides of the belt conveyor along the conveying direction. The belt conveyor is divided into a starting section and a ending section, and the speed of the starting section is less than the speed of the ending section.

[0007] As a preferred embodiment, the lifting and positioning assembly includes a lifting cylinder and a lifting seat. A proximity switch is installed on the lifting seat, and the lifting cylinder drives the lifting seat to extend out from the gap between the two belts of the end section of the conveyor belt.

[0008] As a preferred embodiment, the lifting and positioning assembly comprises four sets. The first three sets of the lifting and positioning assembly each have two connected lifting cylinders, and the lifting base each includes a base plate and a first lifting arm and a second lifting arm vertically installed on both sides of the base plate. The length of the first lifting arm is shorter than the length of the second lifting arm. A connecting rod is also provided between the first lifting arm and the second lifting arm. The upper part of the side of the first lifting arm that is close to the second lifting arm has a stepped structure. The fourth set of the lifting and positioning assembly located at the end of the conveyor line has one lifting cylinder, and the lifting base includes a third lifting arm and a fourth lifting arm of the same length.

[0009] As a preferred embodiment, the flat-push assembly includes a first flat-push assembly and a second flat-push assembly. The first flat-push assembly is driven to rise and fall by a lifting cylinder. Both the first flat-push assembly and the second flat-push assembly include a flat-push cylinder and a flat-push plate, and the flat-push plate is driven by the flat-push cylinder.

[0010] As a preferred embodiment, the gripping assembly includes stator gripping inner jaws and lead wire clamps, and several sets of stator gripping inner jaws and lead wire clamps are mounted on a connecting plate.

[0011] As a preferred embodiment, the stator gripping inner jaw includes a gripping cylinder, a mold core, a push rod, and gripper pieces. The gripping cylinder is connected to the push rod, and the end of the push rod has a tapered structure. Several gripper pieces are slidably installed on the outer peripheral wall of the mold core and expand or contract under the drive of the push rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model positions and lifts the stator through a lifting and positioning component, thereby facilitating the gripping component; the gripping component consists of a stator gripping inner jaw for gripping the stator and a lead wire gripper for clamping the lead wire, which can grip the stator and clamp the lead wire at the same time, facilitating subsequent assembly with the rear end cover; the guide component ensures that the lead wire faces forward during the transport process; the stator is gripped by an internal gripping method, with the gripper retracting into the stator's inner hole, completely eliminating the spatial interference of the lead wire gripper to the traditional external gripping method; the internal gripping stator gripping inner jaw is driven by a cylinder to create a three-lobed elastic gripper, and the radial opening and closing of the gripper is achieved by the axial movement of the push rod, meeting the gripping needs of stators of various specifications.

[0017] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale.

[0021] like Figures 1 to 7 As shown, a stator feeding mechanism includes a conveyor line 1, a lifting and positioning assembly 2, a horizontal pushing assembly 3, and a gripping assembly 4. The conveyor line 1 is a belt conveyor with side guards on both sides along the conveying direction. The belt conveyor is divided into two sections: a starting section 11 and a ending section 12. The speed of the starting section 11 is lower than that of the ending section 12. The stator 6 is manually placed from the stator frame onto the starting section 11 and then conveyed to the ending section 12. Sensors are installed at both the beginning and end of the ending section 12. The end of line 12 is also provided with a retaining edge. The belt on the end section of the belt line 12 is a two-section type arranged along the conveying direction, with a gap between the two belts to form a strip-shaped gap, so as to facilitate the ejection of the lifting and positioning component 2. The lifting and positioning component 2 is installed below the end section of the belt line 12 and is used to lift and position the stator 6 upward. The flat pushing component 3 is installed on one side of the end section of the belt line 12 and is used to push the stator 6 to one side of the conveyor line 1 and position it again. The gripping component 4 is located at the end of the end section of the belt line 12 and is driven by the XZ linear module 5 to grip the stator 6.

[0022] In one embodiment, a guide assembly 7 is also included, which is installed on the initial section of the conveyor belt 11. The guide assembly 7 includes an L-shaped mounting base 71, a stator coil guide rod 72, and a stator core guide rod 73. The stator coil guide rod 72 and the stator core guide rod 73 are both installed on the mounting base 71 through corresponding guide rod mounting bases. The stator coil guide rod 72 is located on the side closer to the stator 6 and is used for guiding the coil. The stator core guide rod 73 is located on the side slightly away from the stator 6 and is used for guiding the core, so that the stator 6 keeps the lead wire 61 facing forward when it is conveyed on the conveyor belt 1.

[0023] In one embodiment, the lifting and positioning assembly 2 includes a lifting cylinder 21 and a lifting seat 22. Since there are four gripping positions, there are corresponding four sets of lifting and positioning assemblies 2. Starting from the side closest to the starting section of the conveyor belt 11, they are divided into a first lifting and positioning assembly, a second lifting and positioning assembly, a third lifting and positioning assembly, and a fourth lifting and positioning assembly. The first three sets of lifting and positioning assemblies 2 closest to the starting section of the conveyor belt 11 each have two lifting cylinders 21. The piston rod of the lower lifting cylinder 21 is connected to the piston rod of the upper lifting cylinder 22. The bottom of 1 is connected, and the first three sets of lifting seats 22 near the starting section of the conveyor belt 11 have the same structure and each includes a base plate 221 and a first lifting arm 222 and a second lifting arm 223 vertically installed on both sides of the base plate 221. The length of the first lifting arm 222 is shorter than the length of the second lifting arm 223. A connecting rod 224 is also provided between the first lifting arm 222 and the second lifting arm 223. The upper part of the side of the first lifting arm 222 that is close to the second lifting arm 223 has a stepped structure; the fourth set of lifting and positioning groups Component 2 has only one lifting cylinder 21, and the lifting base 22 includes a third lifting arm 225 and a fourth lifting arm 226 of the same length. A connecting rod 224 connects the third lifting arm 225 and the fourth lifting arm 226. The upper part of the side of the third lifting arm 225 and the fourth lifting arm 226 that is close to each other also has a stepped structure. Two proximity switches are installed on the second lifting arm 223. One of them is at the same height as the top of the first lifting arm 222, and the other proximity switch is at a height below the second lifting arm 223. When the lifting arm 223 is near the top, the first stator 6, which is conveyed from the starting section belt 11, stops at the end of the last section belt 12. The second stator 6 is conveyed to the third lifting and positioning assembly. When the proximity switch on the assembly detects the arrival of the stator 6, the lifting cylinder 21 below operates, extending the second lifting arm 223 out from the gap between the two belts while the first lifting arm 222 remains closed, thus blocking the stator 6 and preventing it from moving forward. The subsequent two stators 6 are conveyed and positioned in this way.

[0024] In one embodiment, the flat-pushing assembly 3 includes a first flat-pushing assembly for pushing the first three sets of stators 6 and a second flat-pushing assembly for pushing the fourth set of stators 6. To avoid interference when the stators 6 are conveyed on the end section of the belt 12, the first flat-pushing assembly is driven by a lifting cylinder 33. When the stator 6 passes by, the lifting cylinder 33 lifts the first flat-pushing assembly. When flat-pushing is required, the lifting cylinder 33 lowers the first flat-pushing assembly. Both the first and second flat-pushing assemblies include a flat-pushing cylinder 31 and a flat-pushing plate 32. The flat-pushing plate 32 is driven by the flat-pushing cylinder 31. After the stator 6 is lifted and positioned by the corresponding lifting seat 22, the flat-pushing cylinder 31 drives the flat-pushing plate 32 to push the stator 6 to one side and reposition it. After positioning, the four sets of lifting cylinders 21 work to lift the stator 6 upward so that it is disengaged from the belt 12, thus facilitating the subsequent gripping by the gripping assembly 4.

[0025] In one embodiment, the gripping assembly 4 includes stator gripping inner jaws 41 and lead wire clamps 42. All four sets of stator gripping inner jaws 41 and lead wire clamps 42 are mounted on a connecting plate 43. The connecting plate 43 is slidably mounted on the Z-axis linear module 51 via a lifting plate 44. The stator gripping inner jaws 41 are used to grip the stator 6. Specifically, the stator gripping inner jaws 41 include a gripping cylinder 411, a mold core 412, a push rod 413, and gripper plates 414. The gripping cylinder 411 is connected to the push rod 413, thereby driving the push rod 413 to rise and fall. The end of the rod 413 is tapered. Three gripper pieces 414 are slidably mounted on the outer peripheral wall of the mold core 412 and expand or contract under the drive of the push rod 413. When gripping the stator 6, the gripping cylinder 411 drives the push rod 413 to descend, thereby causing the three gripper pieces 414 to expand outward and grip the stator 6. The lead wire gripper 42 is used to clamp the lead wire 61 on the stator 6. Specifically, the lead wire gripper 42 includes a pneumatic gripper and fingers mounted on the pneumatic gripper. The pneumatic gripper drives the two fingers to close, thereby clamping the lead wire 61.

Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
