[0010] According to the above technical solution, the clamping device further includes a slide rod, a B cylinder, a piston plate, a push rod, a B fixing rod, an airbag, a cylinder, a piston ring, and a sliding button.

[0013] According to the above technical solution, the release button is electrically connected to the electric push rod, the bottom of the trigger block is set as an inclined surface, the lower half of the trigger block is provided with a tooth groove, the circumferential surface of the hydraulic rod is provided with an air hole, the interior of the hydraulic rod is provided with hydraulic oil, the gear is meshed with the rack, the gear is meshed with the tooth groove of the trigger block, the trigger block moves downward to drive the rack to move upward, the rack moves upward to drive the placement plate to move upward, so as to place the battery, and a No. 3 spring is arranged between the trigger block and the placement plate.

[0014] The present invention provides a transfer device for new energy battery testing, which has the following beneficial effects: (1) The present invention, through the setting of the clamping device, allows the batteries to enter the placement block in sequence from the feed port, and the A pressure rod is moved upward by the sensor in conjunction with the electric push rod, the cylinder and the piston. The A pressure rod moves upward so that the A pressure rod is disengaged from the inclined surfaces of the clamping claws on both sides. The upward movement of the A pressure rod drives the slide plate to move upward, so that the overall height of the clamping claw is higher than the placement block, thereby preventing the position of the placement block from conflicting during movement and causing the battery to be unable to be transferred. After the A pressure rod is disengaged, the clamping claws on both sides are moved toward the center to cooperate with the bumper rod and the pressure plate to stabilize the upper part of the battery. The movement of the A pressure rod causes the battery to be clamped by the A clamping claw and the B clamping claw to cooperate with the support block to achieve anti-drop protection for the lower part of the battery.

[0015] (2) In the present invention, through the setting of the clamping device, after the battery is clamped by the A jaw moving leftward, the slider is driven to move through the reciprocity of force. The movement of the slider will squeeze the gas in the A cylinder and cooperate with the piston plate to make the push rod squeeze the airbag. The gas in the airbag is transported through the pipeline to the cylinder, causing the piston ring to move towards the sliding button until it contacts the sliding button. At this time, the linear motor starts to drive the sliding block to move leftward, realizing the transfer of the battery.

[0016] (3) In the present invention, through the setting of the material holding device, when the sliding block contacts the release button, the linear motor stops working at this time. At this time, the B jaw contacts the trigger block, causing the trigger block to descend. The descent of the trigger block cooperates with the gear, fixed frame, and rack to drive the placement plate to rise, realizing the holding of the battery. At the same time, the electric push rod moves downward. The downward movement of the electric push rod cooperates with the cylinder and piston to drive the A pressing rod to descend. The descent of the A pressing rod will squeeze the inclined surfaces of the two jaws, causing the two jaws to move outward, realizing the release of the battery. At this time, the battery drops to the top of the placement plate. Due to the weight of the battery, the placement plate descends. The descent of the placement plate cooperates with the fixed column, hydraulic rod, and B pressing rod to cushion the fall of the battery and prevent the battery from being damaged.

[0026] When this embodiment works: The materials are fed into the placing block 501 in sequence from the feeding port 3. When the inductor 5011 senses the battery, the movable end of the electric push rod 502 moves upward. When the movable end of the electric push rod 502 moves upward and drives the piston 504 to move upward, the gas in the A cylinder 503 is released, so that the A pressure rod 505 moves upward. The upward movement of the A pressure rod 505 drives the slide plate 5012 to move upward, realizing that the clamping device is higher than the placing block 501 to prevent the position conflict with the placing block 501 during the transfer process. The upward movement of the A pressure rod 505 will disengage from the inclined surfaces of the two jaws.

By conveying the gas through the pipeline into the cylinder 607, the piston ring 608 moves towards the sliding button 609 until it contacts the sliding button 609.

[0029] When the present embodiment is working, when the linear motor drives the sliding block 4 to slide until it contacts the release button 701, the linear motor stops moving, and at this time, the B clamping claw 507 contacts the trigger block 702 to make the trigger block 702 move downward, and the trigger block 702 moves downward to drive the rack 709 to move upward, and the rack 709 moves upward to drive the placement plate 706 to move upward, so as to place the battery, and at the same time, the electric push rod 502 moves downward, and the electric push rod 502 moves downward to drive the piston 504 to move downward, and the piston 504 moves downward to squeeze the gas in the A cylinder 503 to make the A pressure rod 505 move downward, and the A The downward movement of the pressure rod 505 will squeeze the inclined surfaces of the clamping claws on both sides, causing the clamping claws on both sides to move outward to release the battery. At this time, the battery falls to the top of the placement plate 706, and the placement plate 706 is driven down by the weight of the battery.
