[0060] The implementation principle of the blanking device for the tunnel furnace is as follows: when the battery piece is processed, the battery piece enters the tunnel furnace 1 from one end of the tunnel furnace 1 to be heated, then is conveyed out through the outlet of the tunnel furnace 1 and slides along the blanking inclined plate 3, and the battery piece slides onto the buffer plate 41;

[0061] Then the driving motor is started, which can drive the screw to rotate. When the screw rotates, the sliding frame 51 slides to the position close to the discharging inclined plate 3, and the sliding frame 51 drives the transfer claw 52 to slide to the position close to the discharging inclined plate 3. When the rotating plate 531 moves to the position of the extrusion rod 422, the end face of the extrusion rod 422 away from the tunnel furnace 1 can extrude the rotating plate 531. When the rotating plate 531 continues to slide to the position of the extrusion rod 422, the extrusion rod 422 can extrude the rotating plate 531 and drive the rotating plate 531 to rotate. The rotating plate 531 drives the top end of the transfer claw 52 to rotate to the position close to the rack one 441, and compresses the torsional spring 532. The transfer claw 52 rotates to the horizontal position. At this time, the transfer claw 52 is overlapped on the upper surface of the extrusion rod 422, and the transfer claw 52 is located between the adjacent two buffer plates 41.

[0062] When the sliding frame 51 slides to the position close to the discharging inclined plate 3, the rack one 441 slides to the position close to the discharging inclined plate 3. The rack one 441 can be inserted into the gap groove of the discharging inclined plate 3 and engaged with the gear one 442. When the rack one 441 continues to slide to the position close to the discharging inclined plate 3, the rack one 441 drives the gear one 442 to rotate. The gear one 442 drives the rotating roller 431 to rotate, and further drives the rotating belt 432 to rotate. The rotating belt 432 drives the buffer plate 41 to descend, and the buffer plate 41 conveys the battery piece on it downward.

[0063] When the buffer plate 41 drives the battery piece to descend to the position of the transfer claw 52, the sliding frame 51 stops sliding. At this time, the driver one 61 is started, which can drive the discharging inclined plate 3 to slide away from the sliding frame 51. The discharging inclined plate 3 can drive the elastic member one 62 to slide, and further drive the adjusting frame 421 to slide. The adjusting frame 421 drives the extrusion rod 422 to slide. At this time, the extrusion rod 422 no longer extrudes the rotating plate 531. The torsional spring 532 releases the elastic restoring force, which can drive the rotating plate 531 to rotate, and further drive the transfer claw 52 to rotate and reset. During the rotation of the transfer claw 52, the adjacent two transfer claws 52 clamp the two ends of the battery piece on the buffer plate 41, and transfer the battery piece from the buffer plate 41 to the transfer claw 52. The side surface of the battery piece is attached to the side surface of the transfer claw 52 away from the discharging inclined plate 3.

[0064] Then the driving motor is started, which can drive the screw to rotate. When the screw rotates, the sliding frame 51 slides to the position close to the discharging inclined plate 3, and the sliding frame 51 drives the transfer claw 52 to slide to the position close to the discharging inclined plate 3. When the rotating plate 531 moves to the position of the extrusion rod 422, the end face of the extrusion rod 422 away from the tunnel furnace 1 can extrude the rotating plate 531. When the rotating plate 531 continues to slide to the position of the extrusion rod 422, the extrusion rod 422 can extrude the rotating plate 531 and drive the rotating plate 531 to rotate. The rotating plate 531 drives the top end of the transfer claw 52 to rotate to the position close to the rack one 441, and compresses the torsional spring 532. The transfer claw 52 rotates to the horizontal position. At this time, the transfer claw 52 is overlapped on the upper surface of the extrusion rod 422, and the transfer claw 52 is located between the adjacent two buffer plates 41.

[0065] The driving device one 61 can drive the blanking inclined plate 3 to slide towards the sliding frame 51, the blanking inclined plate 3 can drive the elastic member one 62 to slide, and then drive the adjusting frame 421 to slide, the adjusting frame 421 drives the extrusion rod 422 to slide, and the extrusion rod 422 and the blanking inclined plate 3 are reset;

[0066] The sliding frame 51 drives the transfer claw 52 and the battery piece to slide towards the conveying device 7, when it is needed to convey the battery piece to the conveying belt of one conveying device 7, the driving device two 72 is started first, the driving device two 72 can drive the mounting frame to be adjusted in height, so that one set of conveying devices 7 correspond to the sliding frame 51, and the other set of conveying devices 7 do not block the normal sliding of the sliding frame 51, when the adjusting part 512 slides towards the stop block 8, and the adjusting part 512 moves to the stop block 8, the stop block 8 can pass through the sliding part 511, and block the adjusting part 512, when the adjusting part 512 continues to move, the stop block 8 pushes the adjusting part 512, so that the sliding part 511 and the adjusting part 512 are away from each other, and the elastic member two 513 is stretched, the adjusting part 512 drives the rack two 91 to slide towards the tunnel furnace 1, the sliding part 511 drives the gear two 92 to slide away from the tunnel furnace 1, the rack two 91 can drive the gear two 92 to rotate, when the gear two 92 rotates, the rotating shaft of the transfer claw 52 can be driven to rotate, and the top end of the transfer claw 52 rotates towards the rack one 441, in the rotating process of the transfer claw 52, the battery piece rotates with the transfer claw 52, when the transfer claw 52 rotates to the inclined setting, the battery piece can slide along the transfer claw 52, and falls on the conveying belt of the conveying device 7;

[0067] After a plurality of battery pieces are conveyed to the conveying belt of the conveying device 7, the sliding frame 51 moves away from the conveying device 7, when the stop block 8 no longer blocks the adjusting part 512, the elastic member two 513 releases the elastic restoring force, the adjusting part 512 drives the rack two 91 to reset, the rack two 91 can drive the gear two 92 to rotate, when the gear two 92 rotates, the rotating shaft of the transfer claw 52 can be driven to rotate, and the top end of the transfer claw 52 rotates away from the rack one 441, the transfer claw 52 rotates to the inclined setting, the rack two 91 and the gear two 92 are no longer engaged (the state is shown in Figure 3 The sliding frame 51 continues to slide towards the blanking inclined plate 3, and another group of battery pieces are transferred;

[0068] Meanwhile, the motor is started to drive the conveying roller to rotate, and the conveying roller drives the conveying belt to rotate, and the conveying belt can convey the battery piece thereon. When the battery piece moves to the lower side of the suction disc 102, the driver three 101 is started to drive the suction disc 102 to descend, and the suction disc 102 descends to the conveying belt and sucks the battery piece on the conveying belt. Then, the driver three 101 and the suction disc 102 move along the width direction of the tunnel furnace 1 to convey the battery piece. Through the circulation of the driver three 101 and the suction disc 102, the continuous feeding operation of the battery piece is realized.
