Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0019] Please refer to Figures 1 to 5, the present utility model provides a technical solution: a battery pack screw disassembling and recycling device, which comprises a connecting plate 1, a protective shell 2, a screw disassembling component 3, a bit component 4 and a back plate 34. The screw disassembling component 3 includes a fixed bottom plate 12. On one side of the fixed bottom plate 12, a first cylinder assembly 11 is fixedly connected. The piston end of the first cylinder assembly 11 is fixedly connected with a cylinder connecting plate 7. One end of the cylinder connecting plate 7 extends to the other side of the fixed bottom plate 12 and is fixedly connected with a fixed seat 9. On one side of the fixed bottom plate 12, a linear guide rail 13 is fixedly connected. A slider is arranged inside the linear guide rail 13, and one end of the slider is connected with one side of the fixed seat 9. A first mounting seat 6 is locked on the top of the fixed seat 9, and a spline sleeve assembly 10 is locked on the bottom of the fixed seat 9. A first motor 5 is installed on the first mounting seat 6. A pedestal-mounted linear bearing 15 is installed on one side of the fixed bottom plate 12. A spline shaft 14 is arranged inside the spline sleeve assembly 10. The bottom end of the spline shaft 14 passes through the pedestal-mounted linear bearing 15 and extends below the pedestal-mounted linear bearing 15 and is installed with a bit connecting rod 16. The output end of the first motor 5 and inside the first mounting seat 6 is fixedly connected with a transmission shaft 8. One end of the transmission shaft 8 is connected with the spline sleeve assembly 10.

[0020] On one side of the fixed bottom plate 12, a bit component 4 is installed. The bit component 4 is composed of a second motor 17, a second mounting seat 18, a driving gear 19, a driven gear 20, a pedestal-mounted bearing 21, a rotating shaft 22, a bit disc assembly 23, a material box 24, a guiding cylinder 25, a mounting bottom plate 26, a pulling cylinder 27, a discharging cylinder 28, a baffle 29 and a rotating cylinder 30.

[0021] The second mounting seat 18 is fixedly connected to one side of the mounting bottom plate 26. One side of the mounting bottom plate 26 is fixedly installed on one side of the fixed bottom plate 12. A pedestal-mounted bearing 21 is installed on one side of the mounting bottom plate 26 and below the second mounting seat 18. A rotating shaft 22 is arranged inside the pedestal-mounted bearing 21. The top end of the rotating shaft 22 is provided with a driven gear 20. A second motor 17 is installed on the top of the second mounting seat 18. The output end of the second motor 17 extends below the second mounting seat 18 and is fixedly sleeved with a driving gear 19 meshing with the driven gear 20. A bit disc assembly 23 is arranged on the outer side of the rotating shaft 22. A material box 24 is fixedly connected to one side of the mounting bottom plate 26 and below the rotating shaft 22. A rotating cylinder 30 is fixedly connected to the bottom of the material box 24. The piston end of the rotating cylinder 30 extends above the material box 24 and is installed with a baffle 29. A pulling cylinder 27 is fixedly connected to one side of the mounting bottom plate 26. The piston end of the pulling cylinder 27 is installed with a discharging cylinder 28. A guiding cylinder 25 is installed at the bottom of the material box 24.

[0022] A number of magnetic sleeves 31 are installed inside the bit head disk assembly 23. Sleeve installation holes are provided inside the bit head disk assembly 23 and on the outer sides of the magnetic sleeves 31, and second spring positioning beads 33 are installed inside the sleeve installation holes. A first groove is provided on the outer side of the magnetic sleeve 31, and the second spring positioning bead 33 is stuck in the first groove. A number of first spring positioning beads 32 are installed inside the magnetic sleeve 31. A number of second grooves are provided on the bit head connecting rod 16 and are matched with the first spring positioning beads 32. The second spring positioning bead 33 is stuck in the first groove on the outer side of the magnetic sleeve 31 under the action of elastic force, so as to keep the magnetic sleeve 31 in a fixed position in the bit head disk assembly 23.

[0023] One side of the fixed base plate 12 is fixedly connected with a connection disk 1, and the back of the fixed base plate 12 is fixedly connected with a back plate 34. One end of the connection disk 1 passes through the back plate 34 and extends to the outside of the back plate 34.

[0024] The surface of the fixed base plate 12 is fixedly connected with a protective shell 2. One end of the first motor 5 extends to the outside of the protective shell 2. The device can be locked to the end of the robot arm through the connection disk 1 and used as an end effector. By carrying a machine vision system, actions such as the recognition, disassembly, and recycling of screws in the battery pack can be realized.

[0025] In summary, when the battery pack screw disassembly and recycling device is in use, the piston end of the first cylinder assembly 11 drives the cylinder connection plate 7 to move, so that the cylinder connection plate 7 drives the fixed seat 9, the first motor 5, the first mounting seat 6, and the spline sleeve assembly 10 to move. The bit head connecting rod 16 can be driven to perform up-and-down and rotation actions through the connection with the spline sleeve assembly 10 by the spline shaft 14 under the guiding action of the linear bearing with seat 15 and the rotation action of the first motor 5.

[0026] When the second motor 17 rotates, it drives the driving gear 19 to rotate, thereby driving the driven gear 20, the rotating shaft 22, and the bit head disk assembly 23 to rotate by a set angle, so that the magnetic sleeve 31 in the bit head disk assembly 23 is accurately aligned with the center of the guiding cylinder 25, and the second motor 17 stops working.

[0027] Before disassembling the screw, the piston end of the material pulling cylinder 27 drives the unloading cylinder 28 to push out, aligning the center of the unloading cylinder 28 with the guiding cylinder 25. The piston end of the rotating cylinder 30 drives the baffle 29 to rotate clockwise by 90° to the lower part of the unloading cylinder 28 to prevent the magnetic sleeve 31 from falling before engaging with the bit connecting rod 16. Driven by the downward movement of the first cylinder assembly 11, the bit connecting rod 16 moves downward and pushes the magnetic sleeve 31 to break through the elastic force of the second spring positioning bead 33, causing the second spring positioning bead 33 to disengage from the first groove on the outer side of the magnetic sleeve 31. The magnetic sleeve 31 can move downward with the bit connecting rod 16 and stop on the baffle 29. Under the continuous downward movement of the bit connecting rod 16, the first spring positioning bead 32 in the magnetic sleeve 31 snaps into the second groove in the bit connecting rod 16. The rotating cylinder 30 drives the baffle 29 to rotate counterclockwise by 90° so that the magnetic sleeve 31 can pass downward through the guiding cylinder 25 to reach the working position for disassembling the screw, and the magnetic sleeve 31 is sleeved with the screw cap. When disassembling the screw, driven by the first motor 5, the bit connecting rod 16 drives the magnetic sleeve 31 to rotate in the reverse screw direction to disengage the screw from the fixed surface. The first motor 5 stops working, and the screw is adsorbed on the magnetic sleeve 31 and moves upward with the bit connecting rod 16 and the magnetic sleeve 31 driven by the first cylinder assembly 11. When the screw moves inside the unloading cylinder 28, the rotating cylinder 30 drives the baffle 29 to rotate clockwise by 90° to the lower part of the unloading cylinder 28 to prevent the screw from falling. At the same time, the material pulling cylinder 27 drives the unloading cylinder 28 to retract, and brings the screw to the discharge port of the material box 24 so that the screw falls into the material box 24 to complete the screw recovery. The bit connecting rod 16 drives the magnetic sleeve 31 to continue moving upward into the bit disc assembly 23. Under the elastic force of the second spring positioning bead 33, the first groove on the outer side of the magnetic sleeve 31 is clamped. And under the limiting action of the small-diameter boss hole at the upper end of the sleeve mounting hole of the bit disc assembly 23, the first spring positioning bead 32 in the magnetic sleeve 31 disengages from the second groove in the bit connecting rod 16. The bit connecting rod 16 continues to move upward under the drive of the first cylinder assembly 11 to return to the initial position, and the disassembly is completed.
