Description

Technical Field

[0001] The present invention relates to the technical field of motor assembly, and in particular to an automatic motor assembly device. Background Art

[0002] In the prior art, the problem of discrete processes in motor assembly is prominent. Each process link adopts an independent workstation design, relying on conveyor belts or manual transfer to form a bottleneck in the production rhythm, resulting in low overall equipment utilization rate. Secondly, the traditional linear assembly line has defects in space layout. It not only occupies a large factory area, but also the inspection equipment needs to be separately demarcated, and the problem of cross-reverse logistics path is significant. More importantly, the existing motor assembly technology has systematic shortcomings such as lagging quality control, insufficient production line flexibility, and automation limitations. It is manifested as the detection of key parameters is set at the terminal station, resulting in lagging defect discovery, the high proportion of special equipment makes it difficult to change models, and the precision assembly link still relies on manual operation. These factors jointly restrict the improvement of production efficiency and product quality. Summary of the Invention

[0003] The purpose of the present invention is to provide an automatic motor assembly device for the defects existing in the prior art, achieving the effect of integrating processes such as motor unstacking, laser marking, vision inspection, electrical performance testing, and worm gear pressing into a continuous production process, significantly improving production efficiency, enabling rapid model change, ensuring assembly quality, and being able to complete the full-process automatic assembly of motors within a limited site through a compact space plan.

[0004] To achieve the above purpose, the technical solution adopted by the present invention is: including a motor incoming material unstacking position, an upper loading station robot, a motor and worm gear pressing station, a worm gear upper loading station, a lower loading station robot, and a lower loading palletizing; the motor incoming material unstacking position and the motor and worm gear pressing station are arranged on the same movement trajectory of the upper loading station robot for motor loading, the lower loading palletizing and the motor and worm gear pressing station are arranged on the same movement trajectory of the lower loading station robot for unloading, and the worm gear upper loading station performs worm gear loading for the motor and worm gear pressing station.

[0005] Further, the worm feeding station includes a quick-change structure for worm feeding and a servo up-and-down movement mechanism. The worms are stacked in a number of horizontal channels vertically distributed on the quick-change structure for worm feeding. The servo up-and-down movement mechanism drives the quick-change structure for worm feeding to move up and down. An air blowing mechanism is arranged directly in front of the horizontal channels. At the outer ends of a number of the horizontal channels on the quick-change structure for worm feeding, a position-blocking mechanism is provided. A position-blocking spring is arranged on the back of the position-blocking mechanism. The position-blocking spring imparts elasticity to the position-blocking mechanism when it is subjected to axial pressure. At the end of the quick-change structure for worm feeding, a quick-change baffle for worm feeding is provided. Between the position-blocking mechanism and the quick-change baffle for worm feeding is a worm gripping space.

[0006] Further, a material-taking gripper is arranged on the front of the quick-change structure for worm feeding. The material-taking gripper moves between the motor and worm pressing station and the worm feeding station through a turntable and performs worm feeding.

[0007] Further, the motor and worm pressing station includes a worm falling through-hole and a motor pushing gripper. When in a vertical state, the motor pushing gripper grabs the motor and then rotates and horizontally advances the motor to below the worm falling through-hole. Above the worm falling through-hole, a pressing servo presses the worm and the motor.

[0008] Further, the quick-change structure for worm feeding is quickly positioned on the servo up-and-down movement mechanism through quick-change structure positioning points and is fixedly installed or disassembled through toggle clamps.

[0009] Further, the horizontal channels are groove structures adapted to the size of the worms, and the front directions of the horizontal channels are kept open.

[0010] Further, a worm stock detection mechanism and a worm in-place detection mechanism are arranged outside the material-taking gripper.

[0011] Further, both the motor incoming material unstacking position and the discharging and stacking positions are provided with full pallets and empty pallets for recycling.

[0012] Further, on the same movement trajectory of the motor incoming material unstacking position of the robot at the feeding station and the motor and worm pressing station, there are also arranged a motor laser marking station, a camera appearance detection station, and an electrical performance detection station. On the same movement trajectory of the discharging and stacking of the robot at the discharging station and the motor and worm pressing station, there is also arranged an appearance and dimensional inspection station after pressing.

[0013] Furthermore, the motor incoming material unstacking position and the discharging stacking are separately arranged on both sides. The feeding station robot and the discharging station robot are arranged between the motor incoming material unstacking position and the discharging stacking. The motor and worm pressing station is arranged at the intersection of the feeding station robot and the discharging station robot outside the motor incoming material unstacking position and the discharging stacking.

[0014] It includes a motor incoming material unstacking position, a feeding station robot, a motor and worm pressing station, a worm feeding station, a discharging station robot and a discharging stacking.

Detailed Embodiment

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0025] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0026] An automatic device for assembling an electric motor, as Figures 1 to 6 shown, includes an unstacking position for incoming motors 1, a loading station robot 2, a pressing station for motors and worms 6, a worm loading station 7, an unloading station robot 9, and an unloading stacking 10; the unstacking position for incoming motors 1 and the pressing station for motors and worms 6 are arranged on the same movement trajectory of the loading station robot 2 for motor loading, the unloading stacking 10 and the pressing station for motors and worms 6 are arranged on the same movement trajectory of the unloading station robot 9 for unloading, and the worm loading station 7 supplies worms to the pressing station for motors and worms 6.

[0027] Specifically, by arranging the motor incoming material unstacking position 1 and the motor and worm pressing station 6 on the same movement trajectory of the loading station robot 2, single-robot synchronous unstacking and feeding of the pressing station are achieved. The trajectory of the unloading station robot 9 integrates unloading and palletizing 10 and the pressing station 6 to form a closed-loop material flow, reducing the need for independent handling equipment in traditional production lines and lowering the system complexity. The worm pressing station 6 is directionally fed by the independent worm loading station 7 to avoid the risk of material mixing and improve the worm positioning accuracy. The worm pressing station 6 serves as both the end point of the loading station robot 2 and the starting point of the unloading station robot 9, thus eliminating the no-load waiting time between workstations in traditional production lines.

[0028] As a preference of the above embodiment, as Figures 1 to 6 shown, the worm loading station 7 includes a worm loading quick-change structure 7-1 and a servo up-and-down movement mechanism 7-2. The worms are stacked in a plurality of horizontal channels 7-1-1 vertically distributed on the worm loading quick-change structure 7-1. The servo up-and-down movement mechanism 7-2 drives the worm loading quick-change structure 7-1 to move up and down. An air blowing mechanism 7-4 is arranged directly in front of the horizontal channels 7-1-1. At the outer ends of the plurality of horizontal channels 7-1-1 on the worm loading quick-change structure 7-1, a in-place blocking mechanism 7-1-2 is arranged. A in-place blocking spring 7-1-3 is arranged on the back of the in-place blocking mechanism 7-1-2. The in-place blocking spring 7-1-3 imparts elasticity to the in-place blocking mechanism 7-1-2 when it is subjected to axial pressure. A worm loading quick-change baffle 7-1-4 is arranged at the end of the worm loading quick-change structure 7-1. A worm grasping space 7-1-5 is formed between the in-place blocking mechanism 7-1-2 and the worm loading quick-change baffle 7-1-4.

[0029] Specifically, through the vertical distribution design of the horizontal channel 7-1-1, the three-dimensional stacking of the worm in a limited space is realized. In cooperation with the precise positioning of the servo up-and-down movement mechanism 7-2, the problem of excessive floor space occupied by traditional horizontal storage is solved, the feeding efficiency of the worm is further improved, and the fast beat brought by the layout of the device body is matched, further improving the overall automatic assembly efficiency. The air blowing mechanism 7-4, the in-place blocking mechanism 7-1-2, and the spring 7-1-3 form a cooperative positioning system. The air blowing mechanism 7-4 first blows air to blow the worms in a row of horizontal channels 7-1-1 to the in-place blocking mechanism 7-1-2. Subsequently, after the in-place blocking mechanism 7-1-2 is squeezed and separated, the air blowing mechanism 7-4 blows air again to blow the worms to the grasping space 7-1-5 and stops them by the quick-change baffle 7-1-4 for worm feeding. The precise stop of the worms in the grasping space 7-1-5 is realized through the two consecutive air blows of the air blowing mechanism 7-4, so as to feed the subsequent motor and worm pressing station 6 more accurately and efficiently. The quick-change structure 7-1 for worm feeding itself forms an integrally detachable unit, which ensures the large-batch feeding and fast feeding of the worms, and can adapt to multi-specification worms by replacing the quick-change structure 7-1 with different channel spacings.

[0030] As a preference of the above embodiment, as Figures 1 to 6 shown, a material taking gripper 7-5 is arranged on the front surface of the quick-change structure 7-1 for worm feeding. The material taking gripper 7-5 moves between the motor and worm pressing station 6 and the worm feeding station 7 through a turntable and feeds the worms.

[0031] Specifically, by integrating the material taking gripper 7-5 with the turntable, the process of worm grasping and transferring is completed. The rotation angle of the turntable and the blowing rhythm of the air blowing mechanism 7-4 form a timing closed loop. After the air blowing mechanism 7-4 blows air for the first time to push the worms to the in-place blocking mechanism 7-1-2, the material taking gripper 7-5 squeezes the blocking mechanism 7-1-2 to release the limit, and then blows air for the second time to send the worms to the grasping space 7-1-5, improving the positioning accuracy and feeding efficiency of worm feeding.

[0032] As a preference of the above embodiment, as Figures 1 to 6 shown, the motor and worm pressing station 6 includes a worm falling through hole 6-1 and a motor pushing gripper 6-2. The motor pushing gripper 6-2 grabs the motor in a vertical state and then rotates and horizontally pushes the motor to the lower part of the worm falling through hole 6-1. A pressing servo 6-3 is arranged above the worm falling through hole 6-1 to press the worm and the motor.

[0033] Specifically, the worm self-aligns by means of gravity through the worm falling through-hole 6-1. The 90° rotation and propulsion of the motor pusher jaw 6-2 form a three-dimensional space cooperation with the falling through-hole 6-1. The combined actions of the motor pusher jaw 6-2 for vertical grasping and horizontal propulsion are such that the stroke of the falling through-hole 6-1 matches that of the pressing servo 6-3, thereby improving the accuracy and efficiency of the pressing of the motor and the worm.

[0034] As a preference of the above-mentioned embodiment, as Figures 1 to 6 shown, the quick-change structure 7-1 for worm loading is quickly positioned on the servo up-and-down movement mechanism 7-2 through the quick-change structure positioning point 7-3-1 and is fixedly installed or disassembled by means of an elbow clamp 7-3.

[0035] Specifically, the quick-change structure positioning point 7-3-1 and the elbow clamp 7-3 enable the quick-change structure 7-1 for worm loading to form an integrally dismountable unit itself, thereby ensuring the large-batch feeding and quick loading of worms, and different quick-change structures 7-1 with different channel spacings can be replaced to adapt to worms of multiple specifications.

[0036] As a preference of the above-mentioned embodiment, as Figures 1 to 6 shown, the transverse channel 7-1-1 is a groove structure adapted to the size of the worm, and the front direction of the transverse channel 7-1-1 remains open.

[0037] Specifically, the front open structure facilitates quick manual feeding and handling of abnormal situations such as jamming, simplifies the channel cleaning and maintenance process, and visually monitors the worm conveying state.

[0038] As a preference of the above-mentioned embodiment, as Figures 1 to 6 shown, a worm stock detection mechanism 7-5-1 and a worm in-place detection mechanism 7-5-2 are arranged on the outside of the material-taking jaw 7-5.

[0039] Specifically, a worm stock detection mechanism 7-5-1 and a worm in-place detection mechanism 7-5-2 are arranged on the outside of the material-taking jaw 7-5 to realize the remaining quantity of worms in the transverse channel 7-1-1 and the accurate positioning state of the worm at the grasping position 7-1-5, and coordinate with the actions of each component.

[0040] As a preference of the above-mentioned embodiment, as Figures 1 to 6 shown, both the motor incoming material unstacking position 1 and the discharging and stacking position 10 are provided with full pallet stacks and empty pallet stacks and are recycled.

[0041] Specifically, the full pallet stack and the empty pallet stack are evenly arranged at the motor incoming material unstacking position 1 and the blanking stacking position 10, and a recycling structure is formed to realize the material cycle of full pallet feeding, empty pallet recycling, and empty pallet reuse. The same station area alternately bears the full pallet and the empty pallet states, improving production continuity, eliminating the downtime for empty pallet replacement in the traditional solution, and achieving uninterrupted continuous production.

[0042] As a preference of the above embodiment, as Figures 1 to 6 shown, on the same movement trajectory of the motor incoming material unstacking position 1 of the loading station robot 2 and the motor and worm gear pressing position 6, there are also arranged a motor laser marking station 3, a camera appearance inspection station 4, and an electrical performance inspection station 5. On the same movement trajectory of the blanking stacking position 10 of the unloading station robot 9 and the motor and worm gear pressing position 6, there is also arranged an appearance dimension inspection station 8 after pressing.

[0043] As a preference of the above embodiment, as Figures 1 to 6 shown, the motor incoming material unstacking position 1 and the blanking stacking position 10 are arranged on both sides. The loading station robot 2 and the unloading station robot 9 are arranged between the motor incoming material unstacking position 1 and the blanking stacking position 10. The motor and worm gear pressing position 6 is arranged at the intersection point of the loading station robot 2 and the unloading station robot 9 outside the motor incoming material unstacking position 1 and the blanking stacking position 10.

[0044] Specifically, on the same movement trajectory of the motor incoming material unstacking position 1 of the loading station robot 2 and the motor and worm gear pressing position 6, there are also arranged a motor laser marking station 3, a camera appearance inspection station 4, and an electrical performance inspection station 5. On the same movement trajectory of the blanking stacking position 10 of the unloading station robot 9 and the motor and worm gear pressing position 6, there is also arranged an appearance dimension inspection station 8 after pressing. The motor incoming material unstacking position 1 and the blanking stacking position 10 are arranged on both sides. The loading station robot 2 and the unloading station robot 9 are arranged between the motor incoming material unstacking position 1 and the blanking stacking position 10. The motor and worm gear pressing position 6 is arranged at the intersection point of the loading station robot 2 and the unloading station robot 9 outside the motor incoming material unstacking position 1 and the blanking stacking position 10. With this structure, the production beat is optimized. A single robot stroke can complete multiple processes, and the waiting time of the robotic arm is avoided through cross-operation. The inspection stations are embedded in the robot trajectory, saving the space of independent stations, and further improving the quality and efficiency of motor assembly.
