[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 3 As shown, a bearing front cover disassembly device according to an embodiment of the present invention includes a disassembly platform 1 and a first storage box 2 disposed on one side of the disassembly platform 1. The disassembly platform 1 includes a flat plate 11, and a limiting pad 12 is provided on the surface of the flat plate 11. A positioning groove 110 for placing the bearing front cover 200 is formed between two adjacent limiting pads 12. An electromagnet 13 is provided in the middle of the positioning groove 110, and a support block 14 is arranged around the electromagnet 13. A through hole 120 is provided on the flat plate 11, and a sliding groove 15 is provided at the bottom of the flat plate 11. The bolts 2003 of the bearing front cover 200 fall into the sliding groove 15 through the through hole 120 and slide into the interior of the first storage box 2 through the sliding groove 15.

[0020] like Figure 4 As shown, the bearing front cover 200 includes a front cover body 2001, a marking plate 2002, bolts 2003, and a gasket 2004. (As...) Figure 3 As shown, the positioning groove 110 between the limiting pads 12 can position the bearing front cover 200. After the bearing front cover 200 is placed upside down into the positioning groove 110, the electromagnet 13 can attract and fix the marking plate 2002. The bolt 2003 falls into the slide groove 15 below the plate 11 through the through hole 120 under the action of gravity, and slides into the first storage box 2 along the slide groove 15. This eliminates the need to disassemble and sort the bolt 2003, and improves the disassembly efficiency of the bearing front cover 200.

[0021] like Figure 3 As shown, the side of two adjacent limiting pads 12 that are close to each other is an arc surface, and the top of the limiting pad 12 is provided with a guide slope 121. The curvature of the inner sidewall of the limiting pad 12 matches the edge curvature of the front cover body 2001, which can provide a good fixing effect for the bearing front cover 200. The guide slope 121 can guide the insertion of the bearing front cover 200, so that the bearing front cover 200 can enter the positioning groove 110 more smoothly.

[0022] In this embodiment, the surface of the plate 11 is provided with three limiting pads 12. The two sides of the limiting pad 12 located in the middle are both arc surfaces, so that the three limiting pads 12 can form two positioning grooves 110, making the structure more compact.

[0023] like Figure 3 As shown, the support blocks 14 are distributed at the vertices of the same equilateral triangle. In this embodiment, there are three support blocks 14, which are arranged at equal intervals around the electromagnet 13, providing stable three-point support for the bearing front cover 200 and keeping the bearing front cover 200 stable during disassembly.

[0024] Furthermore, through holes 120 are formed between two adjacent support blocks 14. Since each bearing front cover 200 includes three bolts 2003, three through holes 120 are also provided, with each bolt 2003 falling into the slide groove 15 through one through hole 120. The through holes 120 are formed by utilizing the gap between the support blocks 14, making full use of the space of the plate 11, and the overall structure is compact.

[0025] like Figure 1 and Figure 2 As shown, the bottom surface of the flat plate 11 is provided with a support leg 16, and the bottom of the support leg 16 is provided with an adjustable base 17, which is threadedly connected to the support leg 16. Since the first storage box 2 has a certain depth, and the slide 15 needs to be located above the first storage box 2, the support leg 16 is used to raise the flat plate 11. In order to facilitate the adjustment of the height of the flat plate 11, the bottom of the support leg 16 is also provided with an adjustable base 17. By turning the adjustable base 17, the height of the flat plate 11 can be finely adjusted to ensure that the flat plate 11 is at a suitable height and remains horizontal.

[0026] like Figure 5 As shown, a robotic arm 3 is also provided on one side of the plate 11. The robotic arm 3 includes a connecting arm 31, a rotating arm 32, and a rotating arm 33 that are hinged together in sequence. The end of the rotating arm 33 is provided with a clamping component 4 for clamping the bearing front cover 200. The electromagnet 13 on the surface of the plate 11 attracts and fixes the sign plate 2002. The robotic arm 3 can move freely. The clamping component 4 at the end of the rotating arm 33 can grasp the front cover body 2001, so that the front cover body 2001 is separated from the sign plate 2002. Finally, the sign plate 2002 and the gasket 2004 are grasped and stored as a whole. No manual disassembly and sorting are required, which has high disassembly efficiency.

[0027] A second storage box 5 is provided on one side of the robotic arm 3. Both the first storage box 2 and the second storage box 5 have a tray 6 at their bottom. The first storage box 2 is used to store bolts 2003, one second storage box 5 is used to stack the front cover body 2001, and the other second storage box 5 is used to stack the signboard 2002 and the gasket 2004. To facilitate the handling of the first and second storage boxes 2 and 5, a tray 6 is provided at the bottom of both.

[0028] The number of second storage boxes 5 is not limited to two; the number of second storage boxes 5 can be flexibly set according to the actual operational needs.

[0029] like Figure 6 As shown, the clamping assembly 4 includes a mounting base 41 connected to the rotating arm 33. One side of the mounting base 41 is provided with a drive member 42, a connecting block 43, and a gripper 44. The connecting block 43 is connected to the output end of the drive member 42, and the gripper 44 is fixedly connected to the connecting block 43. The drive member 42 causes the two connecting blocks 43 to move closer or further apart, and the connecting blocks 43 in turn drive the two grippers 44 to close or open, thereby gripping the front cover body 2001 or the sign plate 2002.

[0030] In this embodiment, the gripper 44 is detachably connected to the connecting block 43. When the gripper 44 is damaged, a new gripper 44 can be directly replaced.

[0031] Furthermore, a protective cover 45 is provided on one side of the mounting base 41, and the driving component 42 is disposed inside the protective cover 45. The protective cover 45 can protect the driving component 42, preventing it from being directly impacted by external forces and improving its reliability. Of course, in order to allow the driving component 42 to connect with the connecting block 43, the protective cover 45 is not completely sealed, and openings are provided on both sides of the protective cover 45.

[0032] Furthermore, a limiting disc 46 is provided on one side surface of the protective cover 45, and the grippers 44 are located on both sides of the limiting disc 46.

[0033] like Figure 3 As shown, when the gripper 44 grips the front cover body 2001, it needs to be engaged into the positioning groove 110 through the gap between the two limiting pads 12. In order for the gripper 44 to accurately grasp the front cover body 2001, the gripper 44 needs to be set at a specific height. In this embodiment, the limiting plate 46 on one side surface of the protective cover 45 can abut against the surface of the front cover body 2001, providing positioning for the gripper 44. In addition, by abutting against the surface of the front cover body 2001, the limiting plate 46 can play a certain limiting role for the front cover body 2001, making it more stable and preventing the front cover body 2001 from shaking and falling off during the gripping process.

[0034] In order to reduce the impact between the limiting plate 46 and the front cover body 2001, a buffer pad with a certain elasticity can be provided on the surface of the limiting plate 46.

[0035] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
