[0019] The following details the specific embodiments of the present utility model in conjunction with the accompanying drawings and preferred embodiments.

[0020] As Figure 1 shown, a flipping mechanism for a polymer soft-pack battery includes a belt conveying mechanism 1, a flipping drive mechanism 2, and a vacuum chuck 3. The flipping drive mechanism is installed on the belt conveying mechanism, and the vacuum chuck is installed on the flipping drive mechanism. The lithium battery is conveyed on the belt conveying mechanism. When it is conveyed to the lower part of the vacuum chuck, the flipping drive mechanism drives the vacuum chuck to flip, thereby flipping the lithium battery by 180°.

[0021] Specifically, the belt conveying mechanism 1 includes a frame 11, a belt motor 12, and a conveyor belt 13. The conveyor belt is installed on the frame, and the belt motor drives the conveyor belt to move. The belt motor drives the conveyor belt to rotate.

[0022] Specifically, the flipping drive mechanism 2 includes a flipping motor 21, a speed reducer 22, a connecting plate 23, a bearing seat 24, and a flipping rod 25. The flipping motor is connected to the speed reducer. The speed reducer is installed on the side of the frame through the connecting plate. The bearing seats are fixed on both sides of the frame. Both ends of the flipping rod are connected to the bearing seats, and one end of the flipping rod is fixedly connected to the output end of the speed reducer. The vacuum suction cup is fixed on the flipping rod through a suction cup adjusting frame 4. Further, a plurality of parallel strip-shaped grooves 41 are provided on the suction cup adjusting frame, and the vacuum suction cup is installed in the strip-shaped grooves. The distance of the vacuum suction cup can be adjusted according to the size of the battery, and the number of vacuum suction cups can be selected through the strip-shaped grooves.

[0023] Further, when the flipping rod drives the lithium battery to flip by 90°, vibrations will occur and the battery is likely to be shaken off. Therefore, buffer mechanisms are provided at both ends of the flipping rod. The buffer mechanisms include buffer blocks 26, buffer block brackets 27, and hydraulic shock absorbers 28. Buffer blocks 26 are respectively fixed at both ends of the flipping rod. Buffer bracket 27 is fixed on the bearing seat corresponding to the buffer block, and a hydraulic shock absorber 28 is fixed on the buffer bracket. The hydraulic shock absorber cooperates with the buffer block. Chamfers are provided on both sides of the buffer block. Specifically, one buffer block is located at the upper part on the left side of the flipping rod, and the other buffer block is located at the lower part on the right side of the flipping rod. When the buffer block follows the flipping rod and flips close to 90°, that is, when the lithium battery is about to be flipped over, the buffer block will contact the hydraulic shock absorber, and the hydraulic shock absorber will squeeze the buffer block, slowing down the flipping speed of the lithium battery, thereby preventing the lithium battery from being shaken off.

[0024] Further, in order to accurately control the flipping angle of the flipping rod, an adjusting frame 5 is fixed on the connecting plate. The adjusting frame is provided with an adjusting groove 6, and a groove sensor 7 is installed on the adjusting groove. A position plate 8 is provided on the output shaft of the speed reducer, and the position plate cooperates with the groove sensor. In order to protect the groove sensor, a protective cover 9 is provided on the outside of the speed reducer and the adjusting frame.

[0025] It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
