[0035] refer to Figure 9 and Figure 10The multi-station parallel power battery graded discharge device also includes a liquid adding mechanism, which includes a piston cylinder 121, a liquid inlet pipe 122, a liquid outlet pipe 123, a piston block 124, an electric push rod 125, a mounting rod 126 and a detector 127.

The detector 127 and the electric push rod 3 125 are both electrically connected to the controller.

[0036] refer to Figure 1 and Figure 11 The multi-station parallel power battery grading discharge device also includes an electric roller 131 and a positioning plate 132. A row of electric rollers 131 are installed at the front of the base frame 1. A positioning plate 132 that can slide back and forth is provided at the front of the base frame 1. A linear driver for driving the positioning plate 132 to slide is installed at the front of the base frame 1. The driving method of the electric roller 131 and the linear driver are existing technologies. Two trapezoidal openings 133 are opened on the rear side of the positioning plate 132.

[0037] Initially, the two discharge frames 2 placed on the base frame 1 are both filled with conductive solution, the limiting block 116 is located between a pair of blocks 1 21 of the left discharge frame 2, and the elastic member is in a compressed state.

[0038] In the first step, the cylindrical small batteries and square large batteries to be discharged are placed into the material frame 101, and the conveyor belt 102 is controlled to rotate intermittently clockwise, and the lifting rod 103 and the lifting bar 105 move with the conveyor belt 102; when the lifting rod 103 lifts the small battery, the small battery falls through the long hole 104 to the lifting bar 105 below, and the small battery is lifted by the lifting bar 105; when the lifting bar 105 lifts the large battery, the center of gravity of the large battery located on the lifting bar 105 is unstable, and the large battery falls onto the lifting rod 103 by gravity, and the large battery is lifted by the lifting rod 103. In this way, the lifting rod 103 can only lift the large battery, and the lifting bar 105 can only lift the small battery. The alternating lifting bars 105 and lifting rods 103 classify and lift the small batteries and large batteries.

[0039] In the second step, when the lifting bar 105 lifts a group of small batteries to the uppermost part of the conveyor belt 2 102, the conveyor belt 2 102 stops rotating, and the group of small batteries falls into the guide frame 2 106. Under the guidance of the bottom of the guide frame 2 106 and the inclined plate 107, the small batteries in the guide frame 2 106 roll to the leftmost separation area above the conveyor belt 1 5, and the conveyor belt 1 5 is controlled to rotate clockwise once, driving the group of small batteries to move right, and the next separation area is located below the right end of the guide frame 2 106; the conveyor belt 2 102 rotates again, and the lifting rod 103 lifts the large battery to the uppermost part of the conveyor belt 2 102, and the conveyor belt 2 102 stops rotating. The large battery falls along the guide frame 2 106 into the leftmost separation area above the conveyor belt 1 5, and the conveyor belt 1 5 rotates again, and so on. The small batteries and large batteries are placed in the separation areas at intervals according to their types.

[0040] In the third step, when the conveyor belt 5 stops rotating, the electric push rod 81 is controlled to drive the small push plate 7 and the large push plate 8 to move forward and then move backward to reset. If there is a small battery in the partition area directly in front of the small push plate 7, the bottom surface of the small push plate 7 is higher than the small battery, the small push plate 7 will not push the small battery in the partition area, and the limiting slope 41 has a blocking effect on the small battery, so that the small battery will not fall into the guide frame 9 on the left, the conveyor belt 5 rotates again, and the small battery is continued to be transported by the conveyor belt 5; the conveyor belt 5 stops rotating, and there is a large battery in the partition area directly in front of the small push plate 7, and the electric push rod 81 is controlled to drive the small push plate 7 and the large push plate 8 to move forward and backward again After one movement, the height of the large battery is higher than the bottom surface of the small push plate 7. Under the guidance of the limiting slope 41 and the slope 90, the forward-moving small push plate 7 pushes the large battery forward to move into the guide frame 9 on the left; then, the small battery on the conveyor belt 5 moves to the front of the large push plate 8, and the forward-moving large push plate 8 pushes the small batteries in the separation area forward to move into the guide frame 9 on the right; in addition, if individual small batteries are mixed into the separation area of ​​the large battery, after the small push plate 7 pushes out the large battery, the moving large push plate 8 will continue to push out the small batteries in the separation area; in this way, the large battery and the small battery can be pushed into two different guide frames 9 respectively.

[0041] In the fourth step, when the large battery or small battery in the guide frame 9 falls on the limit plate 96, the large battery or small battery pushes the limit plate 96 under the action of gravity, causing the limit plate 96 to rotate and open around the rotating shaft 95. The spiral spring deforms and acts as a buffer for the large battery and the small battery under the action of damping, so that the large battery and the small battery can fall into two different discharge frames 2 respectively.

[0042] The fifth step is to control the electric push rod 2 115 to drive the mobile frame 114 to rise, driving the limit block 116, the piston cylinder 121 and the electric push rod 3 125 to rise as a whole. The mobile frame 114 lifts the discharge frame 2 on the left through the lifting part 117, so that the discharge frame 2 on the left leaves the placement position 31. The block 2 22 rises with the discharge frame 2 on the left. The block 2 22 no longer presses down the contact part 93. Under the action of the elastic member, the baffle 92 moves upward along the guide rod 91. The baffle 92 automatically becomes closed. The battery that subsequently enters the guide frame 1 9 will be blocked by the baffle 92.

[0043] The sixth step is to control the screw motor on the translation seat 112 to drive the sliding frame 113 to slide forward, driving the mobile frame 114, the electric push rod 2 115, the limit block 116, the piston cylinder 121, the electric push rod 3 125, the mounting rod 126, the detector 127 and the left discharge frame 2 to move forward as a whole. With the cooperation of the block 1 21 and the limit block 116, the left discharge frame 2 is prevented from being separated from the mobile frame 114, so that the left discharge frame 2 is smoothly transferred to the top of the electric roller 131, and then the control is carried out. The electric push rod 2 115 drives the movable frame 114 to descend, driving the limit block 116, the piston cylinder 121, the electric push rod 3 125 and the left discharge frame 2 to descend until the left discharge frame 2 is placed on the electric roller 131. The electric push rod 2 115 is controlled to make the movable frame 114, the limit block 116, the piston cylinder 121 and the electric push rod 3 125 continue to descend, and the limit block 116 is staggered with a pair of square blocks 1 21. The screw motor is controlled to move the sliding frame 113, the movable frame 114 and the limit block 116 backward.

[0044] In the seventh step, the electric roller 131 is controlled to rotate to transport the left discharge frame 2 to the left for the subsequent large battery discharge process. When the large battery is discharged, the pull rod 30 is pulled up to leave the groove 20, so that the filter frame 3 leaves the discharge frame 2, and the discharged large battery can be quickly taken out. Then the filter frame 3 is put back into the discharge frame 2, and the pull rod 30 is embedded in the groove 20. The electric slide rail 111 is controlled to drive the translation seat 112 to move to the right. Similarly, under the action of the screw motor and the electric push rod 115, the discharge frame 2 on the right can be lifted onto the electric roller 131.

[0045] In the eighth step, the other two discharge frames 2 that have completed the discharge process are transported to the front of the placement position 31 by the electric roller 131, and the linear drive is controlled to drive the positioning plate 132 to move backward. The positioning plate 132 squeezes the two discharge frames 2 through the two trapezoidal openings 133 to correct the position of the discharge frame 2 in the left and right directions, so that the discharge frame 2 is aligned front to back with the placement position 31.

[0046] In the ninth step, the mobile frame 114 is moved in three dimensions by the cooperation of the electric slide rail 111, the screw motor and the electric push rod 2 115. After the mobile frame 114 lifts the discharge frame 2, the electric push rod 2 115 is controlled to make the mobile frame 114 and the discharge frame 2 continue to rise. The detector 127 on the mounting rod 126 extends into the discharge frame 2. The detector 127 detects the concentration of the conductive solution in the discharge frame 2. The concentration detection result is sent to the controller. The controller controls the electric push rod 3 125 to drive the piston block 124 to slide to the right according to the concentration result. The high-concentration conductive solution in the liquid inlet pipe 122 enters the piston cylinder 121. The higher the concentration detection result, the lower the concentration. The smaller the discharge pressure, the greater the amount of high-concentration conductive solution entering. The controller controls the electric push rod 3 125 to drive the piston block 124 to slide to the left and reset. The high-concentration conductive solution in the piston cylinder 121 is squeezed out to the liquid outlet pipe 123, thereby adding the high-concentration conductive solution into the discharge frame 2, automatically maintaining the concentration of the conductive solution in the discharge frame 2, and controlling the position of the movable frame 114 to place the discharge frame 2 in the placement position 31. The block 2 22 presses down the contact portion 93 to open the baffle 92, and the battery falls into the discharge frame 2 again for discharge. In this way, large batteries and small batteries can be automatically classified and discharged, with a high degree of automation and effective improvement of discharge efficiency.
