[0007] The material sorting mechanism comprises a conveyor belt, and the conveyor belt is installed between two side frames, and a plurality of material dividing blocks are installed on the conveyor belt at equal intervals.
[0008] Preferably, a mounting plate is installed on the side wall of the frame, a first motor is installed on the mounting plate, and an output end of the first motor is connected to the center of the rotating seat.
[0009] Preferably, the flip assembly includes a support frame installed on the frame, a second motor is installed on the support frame, and an output end of the second motor is connected to the middle part of the bidirectional pneumatic cylinder.
[0010] Preferably, the two telescopic ends of the bidirectional pneumatic cylinder are respectively installed with U-shaped frames, the U-shaped frames are installed with a unidirectional pneumatic cylinder, and the telescopic ends of the unidirectional pneumatic cylinder are installed with clamping arms, and a CCD camera is installed on one of the clamping arms.
[0011] Preferably, the detection assembly includes an axle seat mounted on the frame, and a rotating shaft is rotatably mounted on the axle seat, rotating teeth and a rotating arm are fixedly mounted on the rotating shaft, the rotating arm is connected to the detection seat, and a detection contact head is mounted on the detection seat facing the frame side.
[0012] Preferably, the detection component also includes a limit plate installed on the frame, and a plurality of guide rods are installed through the limit plate, a wheel seat is installed at one end of the guide rod, and a roller rolling along the swivel seat and the arc-shaped protrusion is installed on the wheel seat, and a spring is installed on the outside of the guide rod and between the limit plate and the wheel seat.
[0013] Preferably, a connecting plate is installed at the other end of a plurality of the guide rods, a rack is installed on the connecting plate, and the rack is meshed with the rotating gear.
[0014] Preferably, a plurality of pneumatic push cylinders are installed on the side frame located on one side of the conveyor belt, and a push plate is installed at the telescopic end of the pneumatic push cylinder, and a plurality of material distribution troughs are installed on the side frame located on the other side of the conveyor belt.
[0015] A sorting method for a cylindrical cell sorting device for a battery replacement battery, the specific operating steps of the sorting device are as follows:
[0016] Step 1: The cylindrical battery cells are stacked in the hopper, and the first motor drives the material distribution seat to rotate. The battery cell slots on the material distribution seat pass through the hopper in turn, and the cylindrical battery cells automatically fall into the battery cell slots. When the cylindrical battery cells rotate to the flip slots, the positive and negative poles of the cylindrical battery cells are checked through the CCD camera. When the positive and negative poles of the cylindrical battery cells are reversed, the two-way pneumatic cylinder contracts and drives the clamping arm to clamp the ends of the cylindrical battery cells. Then the one-way pneumatic cylinder contracts and drives the clamping arm and the cylindrical battery cells to move out of the battery cell slots. At this time, the second motor drives the two-way pneumatic cylinder to rotate 180°, and then the cylindrical battery cells are rotated 180°. After rotation, the cylindrical battery cells are placed in the battery cell slots for further transportation.
[0017] Step 2: The material dividing seat and the rotating seat rotate synchronously, and the roller rolls against the rotating seat and the outer wall of the arc-shaped protrusion under the action of the spring. When the roller is located between the two arc-shaped protrusions, the compressed spring returns to its original state, and the guide rod moves to drive the connecting plate and the rack to translate, and the rack drives the meshing rotating teeth to rotate, thereby realizing the rotation of the rotating shaft and the rotating arm, and then the detection seat and the detection contact head are moved closer to the end of the cylindrical battery cell until they are in contact with the end of the cylindrical battery cell, so as to measure the capacity, internal resistance and voltage of the cylindrical battery cell. When the roller is located on the arc-shaped protrusion, the wheel seat compresses the spring and drives the rack to move. At this time, the rotation of the rotating teeth drives the rotation of the rotating shaft and the rotating arm, thereby rotating the detection seat and the detection contact head to separate from the end of the cylindrical battery cell;
[0018] Step three: When the cylindrical battery cell after inspection reaches the bottom of the loading inspection mechanism, it automatically falls onto the conveyor belt of the unloading and sorting mechanism. As the conveyor belt moves, according to the measured values of the capacity, internal resistance and voltage of the cylindrical battery cell, the pushing pneumatic cylinder drives the pushing plate to move and pushes the cylindrical battery cell to the corresponding material trough.
[0019] The beneficial effects of the present invention are as follows: the end of the cylindrical battery cell passing through the flip groove is scanned by a CCD camera, and when the positive and negative poles of the cylindrical battery cell are reversed, the bidirectional pneumatic cylinder contracts to drive the clamping arm to clamp the end of the cylindrical battery cell, and then the unidirectional pneumatic cylinder contracts to drive the clamping arm and the cylindrical battery cell to move out of the battery cell groove, and at this time, the bidirectional pneumatic cylinder is driven by the second motor to rotate 180°, and then the cylindrical battery cell is rotated 180°, and the positive and negative poles of the cylindrical battery cell are adjusted, so as to avoid the deviation of the measurement data caused by the positive and negative pole range in subsequent detection, which affects the sorting of the cylindrical battery cells;
[0020] The material dividing seat and the rotating seat rotate synchronously, and the battery cell groove corresponds to the arc-shaped protrusion. During the rotation of the rotating seat and the material dividing seat, the roller rolls against the outer wall of the rotating seat and the arc-shaped protrusion under the action of the spring, and drives the guide rod to reciprocate under the action of the spring. The movement of the guide rod drives the connecting plate and the rack to reciprocate, and the rack drives the meshing teeth to rotate, thereby realizing the reciprocating rotation of the rotating shaft and the rotating arm. When the cylindrical battery cell moves to the detection groove, the detection seat and the detection contact head rotate to contact with the end of the cylindrical battery cell, so as to measure the capacity, internal resistance and voltage of the cylindrical battery cell. When the cylindrical battery cell leaves the detection groove, the detection seat and the detection contact head rotate and separate from the end of the cylindrical battery cell. According to the automatic loading rotation of the material dividing seat, the detection contact head automatically contacts the end of the cylindrical battery cell for detection.
