Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] In one embodiment of this utility model, such as Figures 1-7 As shown, a magnetic core assembly device is provided, including a mounting frame 10, and a magnetic core loading platform 20, a magnetic core waiting mechanism 30, a loading robot 40, and a transfer robot 50, all disposed on the mounting frame 10. The magnetic core loading platform 20 has stacked trays, and magnetic cores are placed in the trays. The magnetic core waiting mechanism 30 is located beside the magnetic core loading platform 20. The loading robot 40 picks up the magnetic cores on the magnetic core loading platform 20 and places them onto the magnetic core waiting mechanism 30. The transfer robot 50 picks up the magnetic cores on the magnetic core waiting mechanism 30 with a magnetic pick-up and transfers them to the assembly position for assembly.

[0030] Specifically, the core loading platform 20 is designed for stacking trays containing cores to be assembled. This platform serves as the starting point for core supply, ensuring a continuous supply of cores to the assembly line. The core waiting area 30, located beside the core loading platform 20, temporarily stores cores picked up by the loading robot 40. The loading robot 40 is responsible for picking up cores from the core loading platform 20 and precisely placing them onto the core waiting area 30. The transfer robot 50 picks up cores from the core waiting area 30 and precisely transfers them to the assembly position for assembly. Automated core assembly significantly improves assembly efficiency and reduces the time and cost of manual operation. Precise robot operation reduces human error and improves assembly accuracy and consistency. This device integrates loading, waiting, and transfer functions, enabling a highly efficient core assembly process within a limited space.

[0031] In this example, the magnetic core waiting mechanism 30 includes a waiting base 31, and a lateral limiting component 32 and a longitudinal limiting component 33, both disposed on the waiting base 31. A waiting position 34 is provided on the waiting base 31. The lateral limiting component 32 and the longitudinal limiting component 33 work together to confine the magnetic core within the waiting position 34. Specifically, the lateral limiting component 32 is responsible for limiting the movement of the magnetic core in the horizontal direction, ensuring that the magnetic core maintains the correct lateral position within the waiting position 34. The longitudinal limiting component 33 is responsible for limiting the movement of the magnetic core in the vertical direction, ensuring that the magnetic core maintains the correct longitudinal position within the waiting position 34. The waiting position 34 is a specific area on the waiting base 31 used for temporary storage of the magnetic core. The magnetic core is placed within the waiting position 34, awaiting gripping by the loading robot 40. Through precise lateral and longitudinal limiting, the position of the magnetic core within the waiting slot is more accurate, thereby improving the accuracy of the loading robot 40 in gripping the magnetic core.

[0032] In this example, the lateral limiting assembly 32 includes a lateral limiting cylinder 321, a lateral limiting plate 322, and a lateral limiting rod 323. The lateral limiting cylinder 321 is fixed to the material waiting seat 31, the lateral limiting plate 322 is connected to the moving end of the lateral limiting cylinder 321, and the lateral limiting rod 323 is fixed to the lateral limiting plate 322. Specifically, as a power source, the lateral limiting cylinder 321 is driven by the pressure of compressed air or hydraulic oil to achieve reciprocating motion, providing the power for lateral limiting. The lateral limiting plate 322 is connected to the moving end of the lateral limiting cylinder 321. When the cylinder drives the moving end to move, the lateral limiting plate 322 moves accordingly, thereby achieving lateral pushing or limiting of the magnetic core. The rod 323 is fixed to the lateral limiting plate 322, moves synchronously with the limiting plate, and directly contacts the magnetic core, limiting the lateral movement of the magnetic core within the material waiting position 34.

[0033] In this example, the lateral limiting plate 322 has multiple connecting holes 324 arranged on it, and the lateral limiting rod 323 is connected to the lateral limiting plate 322 by screws. Specifically, the lateral limiting plate 322 is designed with multiple connecting holes 324, which are used to fix the lateral limiting rod 323. The position of the connecting holes 324 can be adjusted according to the position of the lateral limiting rod 323 to accommodate magnetic cores of different sizes.

[0034] In this example, the longitudinal limiting component 33 includes a longitudinal limiting cylinder 331 and a longitudinal limiting plate 332. The longitudinal limiting cylinder 331 is fixed on the waiting seat 31, and the longitudinal limiting plate 332 is connected to the moving end of the longitudinal limiting cylinder 331. The moving direction of the longitudinal limiting plate 332 is perpendicular to the moving direction of the transverse limiting rod 323, and the longitudinal limiting plate 332 is perpendicular to the transverse limiting rod 323. Specifically, as the power source of the longitudinal limiting component 33, the longitudinal limiting cylinder 331 is driven by pneumatic or hydraulic pressure to realize the reciprocating motion of the longitudinal limiting plate 332. Connected to the moving end of the longitudinal limiting cylinder 331, when the cylinder drives the moving end to move, the longitudinal limiting plate 332 moves accordingly, realizing the longitudinal pushing or limiting of the magnetic core. The moving direction of the longitudinal limiting plate 332 is perpendicular to the moving direction of the transverse limiting rod 323, ensuring that the magnetic core is simultaneously limited by both transverse and longitudinal directions within the waiting slot. The longitudinal limiting plate 332 and the transverse limiting rod 323 are perpendicular to each other and work together on the magnetic core to ensure that the magnetic core is precisely fixed in a certain position within the waiting position 34, preventing displacement during assembly.

[0035] In this example, both the loading robot 40 and the transfer robot 50 include a first linear drive assembly 41, a second linear drive assembly 42, a lifting assembly 43, and a pickup assembly 44. The first linear drive assembly 41 is mounted on a mounting bracket, and the second linear drive assembly 42 is connected to the moving end of the first linear drive assembly 41. The lifting assembly 43 is connected to the moving end of the second linear drive assembly 42, and the moving direction of the lifting assembly 43 is perpendicular to the moving direction of the second linear drive assembly 42. The pickup assembly 44 is located at the lifting end of the lifting assembly 43. Specifically, the working principle of the loading robot and the transfer robot 50 is based on the coordinated action of multiple linear drive assemblies and the lifting assembly 43 to achieve precise gripping and transfer of the magnetic core. The loading robot 40, mounted on the mounting bracket, is responsible for moving the main body of the robot in one direction. The lifting assembly 43, connected to the moving end of the first linear drive assembly 41, is responsible for moving in another direction, cooperating with the first linear drive assembly 41 to achieve precise positioning of the robot on a plane. Connected to the moving end of the second linear drive component 42, it is responsible for moving in the vertical direction to adjust the height of the picking component 44, thereby enabling the grasping of targets at different heights. Located at the lifting end of the lifting component 43, it is responsible for the actual grasping action and can be a gripper 46, a suction cup, or other suitable device for grasping magnetic cores.

[0036] In this example, the lifting assembly 43 includes a movable base 431, a lifting cylinder 432, and a lifting seat 433. The movable base 431 is connected to the moving end of the second linear drive assembly 42. The lifting cylinder 432 is mounted on the movable base 431. The lifting end of the lifting cylinder 432 is connected to the lifting seat 433, and the picking assembly 44 is fixed to the lifting seat 433. Specifically, the movable base 431, connected to the moving end of the second linear drive assembly 42, is responsible for moving the lifting assembly 43 horizontally to a predetermined position. Mounted on the movable base 431, it serves as the power source for the lifting assembly 43. The lifting cylinder 432, driven by pneumatic or hydraulic pressure, enables the vertical movement of the lifting seat 433. Fixed to the lifting seat 433, it is responsible for the actual grasping action. When the lifting seat 433 reaches the predetermined height, the picking assembly 44 can perform a grasping or releasing operation.

[0037] In this example, the pickup assembly 44 includes a fixed cylinder 441, a pickup seat 442, and a magnetic pickup block 443. The fixed cylinder 441 is connected to the lifting end of the lifting assembly 43. The pickup seat 442 is connected to the fixed cylinder 441, and a through slot is provided on the pickup seat 442 for the magnetic pickup block 443 to pass through. The magnetic pickup block 443 is connected to the lifting end of the fixed cylinder 441. Specifically, the fixed cylinder 441 is connected to the lifting end of the lifting assembly 43 and serves as the main driving force for the pickup assembly 44. When the cylinder receives a control signal and is filled with compressed air or hydraulic oil, the piston rod inside the cylinder moves, thereby driving the pickup seat 442 and the magnetic pickup block 443 to rise or fall. The pickup seat 442 is connected to the fixed cylinder 441 and moves vertically with the extension and retraction of the cylinder piston rod. The pickup seat 442 is provided with a through slot for the magnetic pickup block 443 to pass through, so as to realize the attraction and release actions.

[0038] This example also includes a tray receiving platform 60, located beside the magnetic core loading platform 20. The loading robot 40 transfers empty trays to the tray receiving platform 60 for stacking. Specifically, the tray receiving platform 60 is located beside the magnetic core loading platform 20. This position is designed to facilitate the loading robot 40 transferring empty trays to the receiving platform after completing the magnetic core gripping. After being transferred to the tray receiving platform 60, the empty trays can be stacked for subsequent unified processing or reuse.

[0039] In this example, the loading robot 40 also includes a tray-picking cylinder 45 and two grippers 46. The tray-picking cylinder 45 is mounted on the lifting assembly 43, and the two grippers 46 are respectively located at the output end of the tray-picking cylinder 45, and are driven to move closer or further apart. Specifically, the tray-picking cylinder 45 is mounted on the lifting assembly 43 and serves as the power source for driving the grippers 46. When the cylinder receives a control signal and is filled with compressed air or hydraulic oil, the piston rod inside the cylinder moves, thereby driving the grippers 46. The tray-picking cylinder 45 is a bidirectional cylinder; through the extension and retraction movement of the tray-picking cylinder 45, the grippers 46 can accurately grasp and release the tray.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
