The fixed frame 5 is fixed at the lower part of the fixed rod 4, the sleeve assembly 9 is arranged in the fixed frame 5, the motor 7 is arranged on the fixed frame 5, and the sleeve assembly 9 is driven to rotate to disassemble the nut.
The sleeve assembly 9 realizes the position movement in space by lifting the fixing rod 4, sliding the connecting frame 3 left and right on the guide rail 8 and sliding the guide rail 8 front and back on the slide rail 2, and disassembles nuts at different positions. The movement track of the sleeve assembly 9 can be determined by detecting the position and the orientation of the battery pack by a vision system, and the detection of the vision system belongs to a common technology in the mechanical field and is not a point of improvement of the present invention, so that a description thereof will not be given here.
The sleeve assembly 9 can be used to disassemble the normal working nut and the scrapped or failed nut, and the specific structure of the sleeve assembly 9 can be referred to in embodiment 2.
Example 2: the sleeve assembly 9 according to the present invention is constructed as shown in fig. 2, and includes a drive shaft 901, a sleeve body 903, and a nut placement box 906.
As shown in fig. 2 and 3, the nut placing box 906 is connected to the fixed frame 5, the nut placing box 906 is provided with a horizontal space for accommodating a nut, the sleeve body 903 is rotatably connected to the nut placing box 906 through a bearing 907, the driving shaft 901 is rotatably connected to a portion of the nut placing box 906 where the horizontal space is not provided, the lower portion of the driving shaft 901 drives the sleeve body 903 to rotate through a pair of meshed gears 902, the upper end of the driving shaft 901 is connected to the motor output shaft 11, and the driving shaft 901 is driven to rotate by the motor output shaft 11.
Referring to fig. 5 again, the sleeve body 903 has a hollow cavity, in which a sleeve 911 for disassembling a nut, such as a hexagonal sleeve, is embedded, and a magnet 904 is further disposed at an opening at the lower end of the hollow cavity, so as to prevent the nut stored in the hollow cavity from falling off; preferably, a ring magnet may be used, or a plurality of magnets may be circumferentially arranged to form a ring-shaped magnet attraction zone. The sleeve 911 is detachably mounted, and the matched sleeve can be replaced conveniently according to the type of the detached nut.
As shown in fig. 3 and 4, the hollow cavity is communicated with the horizontal space of the nut placing box 906, a baffle 909 capable of swinging up and down is arranged at the top of the hollow cavity, the baffle 909 is connected to a rotary connecting seat 910 in an inclined manner, a spiral spring 908 is connected to one side of the baffle 909 opposite to the horizontal space, the large diameter end of the spiral spring 908 is connected to the nut placing box 906, and the small diameter end is connected to the baffle 909. When the coil spring 908 is not subjected to external force, the baffle 909 is in an inclined state, and the intersection position of the hollow cavity and the horizontal space is blocked to a certain extent. When the nuts in the sleeve body 903 accumulate a certain amount, the uppermost nut pushes up the baffle 909, the baffle 909 swings upward and compresses the coil spring 908, and at the same time, the uppermost nut enters the horizontal space, the coil spring 908 releases the elasticity, and pushes the nut to the depth of the horizontal space, so that the nut is far away from the hollow cavity, and then the baffle 909 is reset. When one nut is removed again, the uppermost nut again pushes up the shutter 909, and the foregoing actions are repeated to enter the horizontal space for storage. The horizontal space of the nut placement box 906 is provided with a nut discharge port, which is connected with a conveying hose, and the foremost nut is pushed by the subsequent nut to enter the conveying hose through the nut discharge port to be discharged.
Further, a disc-shaped cutting knife 905 is further provided at the lower end of the sleeve body 903, when a scrapped nut or a fault nut with a difficult-to-detach sleeve is encountered, the cutting edge of the cutting knife 905 can be used for integrally cutting the bolt and the nut, and the integrally-cut bolt and nut cannot enter the sleeve body 903.
Preferably, the torque sensor 11 is mounted on the driving shaft 901, when the nut which is difficult to be detached is encountered, the voltage signal of the torque sensor 11 rises sharply, at this time, the scrapped nut and the bolt are integrally cut off by the cutting blade 905, and the scrapped nut and the bolt are taken away from the station by the magnet 904 at the lower end of the sleeve body 903.
When the battery pack nut is dismounted by using the dismounting equipment, the battery pack and the tray are operated to a station, and the sleeve assembly 9 is driven by the fixed rod 4, the sliding connecting frame 3 and the guide rail 8 to move back and forth, left and right and up and down to a dismounting position; the sleeve body 903 is aligned with the nut to be disassembled, the motor 7 drives the driving shaft 901 to rotate, further torque is applied to the sleeve body 903, the nut to be disassembled is disassembled, the disassembled nut is absorbed at the opening of the sleeve 911 by the magnet 904, when the next nut is disassembled, the previous nut is lifted to a position, and so on, a plurality of nuts are accumulated in the sleeve body 903, when the nut at the uppermost layer contacts the baffle 909, the baffle 909 is pushed down by the top of the lower nut, the baffle 909 is lifted up and enters the nut placing box 906, and the nut is pushed to the depth of the nut placing box 906 along with the reset of the baffle 909; after a certain number of nuts are accumulated in the nut placement box 906, the foremost nut is pushed out, and the nut placement box 906 is discharged along the conveying hose.
In the disassembly of the nut, the torque sensor 11 can detect the real-time torque and transmit an electric signal to the control system; when a scrapped nut is encountered, the sleeve 911 is difficult to unscrew, at which time the electrical signal of the torque sensor 11 suddenly increases, the control system alarms and controls the sleeve assembly 9 to move, the scrapped nut and the bolt are integrally cut off by the cutting blade 905 of the sleeve assembly 9, and then the disassembled part is transferred away from the station by the magnet 904.
The above embodiments are only for illustrating the technical solution of the present invention and not for limiting it, and it should be understood by those skilled in the art that modifications and equivalents may be made to the specific embodiments of the present invention with reference to the above embodiments, and any modifications and equivalents not departing from the spirit and scope of the present invention are within the scope of the claims appended hereto.
