[0015] Figure 3 It is Figure 1 A partial enlarged view of Specific implementation manner:

[0016] In the embodiment, as shown in Figures 1 to 3 A flipping mechanism for a battery module includes a conveying rack 10. The conveying rack 10 includes two front and rear transverse beams 11. A plurality of legs are fixed at the bottom ends of the transverse beams 11. A connecting beam is fixed between the front and rear corresponding legs. A plurality of electric rollers 12 are located between the two transverse beams 11. The two ends of the electric rollers 12 are installed on the two transverse beams 11. During use, by the operation of the electric rollers 12, the battery module placed above can be conveyed from left to right;

[0017] Some of the electric rollers 12 are located at the left part of the two transverse beams 11, and the remaining electric rollers 12 are located at the right part of the two transverse beams 11;

[0018] At the middle top surfaces of both of the two transverse beams 11, connecting seats 13 are fixedly arranged. Both ends of an intermediate rotating shaft 14 are movably connected to the two connecting seats 13 through bearings. A rotating block 20 is fixedly arranged on the intermediate rotating shaft 14. A placing shell 21 is fixedly arranged on the left side wall of the rotating block 20. A placing groove 22 extending rightward is formed in the middle of the left side wall of the placing shell 21. The left ends of the top surface and the bottom surface of the placing groove 22 are both inclined guiding surfaces, and this design facilitates the access of the battery module. The top surface of the placing groove 22 is flush with the top ends of all the electric rollers 12. A horizontal connecting plate is fixedly arranged on the outer side wall of the middle part of the transverse beam 11. A rotary servo motor 15 is fixedly arranged on the top surface of the horizontal connecting plate. The output shaft of the rotary servo motor 15 is fixedly connected to one end of the intermediate rotating shaft 14 extending out of the corresponding connecting seat 13 through a coupling.

[0019] Furthermore, a horizontally extending transverse through groove 221 is formed in the middle of the bottom plate of the placing groove 22. A rodless cylinder 23 is fixedly arranged on the bottom surface of the placing shell 21. The moving block of the rodless cylinder 23 is inserted into the transverse through groove 221. A pushing connecting block 24 extending vertically upward is fixedly arranged on the top surface of the moving block of the rodless cylinder 23. The front and rear side walls of the pushing connecting block 24 are closely attached to the front and rear inner side walls of the transverse through groove 221 (self-lubricating sheets are fixedly arranged on the front and rear side walls of the pushing connecting block 24, so that when it is closely attached to the front and rear inner side walls of the transverse through groove 221, the friction force is reduced, wear is decreased, and jamming is prevented). The top of the pushing connecting block 24 extends out of the top end of the transverse through groove 221, and a pushing block 25 is fixedly arranged on its left side wall.

[0020] Furthermore, the pushing block 25 is a rubber protection block, so that during pushing, the collision on the surface of the battery module is reduced and the surface wear thereof is decreased.

[0021] Furthermore, a downwardly extending concave hole is formed in the top surface of the top plate of the placing shell 21 at the left part of the placing groove 22. A through hole extending downward is formed in the middle of the bottom surface of the concave hole. An upper fixing plate 26 is fixedly arranged on the left part of the top surface of the top plate of the placing shell 21. A limiting block 27 is inserted into the concave hole. A protruding positioning portion 271 extending downward is formed in the middle of the bottom surface of the limiting block 27. The bottom end of the protruding positioning portion 271 extends out of the bottom end of the through hole, and its bottom surface is an inclined surface, with its right end being higher than its left end. A compression spring 28 is inserted into the concave hole. The top end of the compression spring 28 bears on the bottom surface of the upper fixing plate 26, and the bottom end of the compression spring 28 presses against the top surface of the limiting block 27. The edge of the bottom surface of the limiting block 27 presses against the bottom surface of the edge of the concave hole.

[0022] Furthermore, a limiting plate 1 is provided between two transverse beams 11 on the left and right parts of the middle rotating shaft 14. The front and rear ends of the limiting plate 1 are fixed on the inner side walls of the two transverse beams 11. Plastic protection plates 2 are fixed in the middle of the top surface of the limiting plate 1. The top surface of the left plastic protection plate 2 is pressed against the bottom surface of the rodless cylinder 23, and the top surface of the right plastic protection plate 2 corresponds to the top surface of the placement housing 21.

[0023] Furthermore, side plate bodies 30 are fixed on the top surfaces of the two transverse beams 11 at the left side of the placement housing 21. The same upper horizontal plate 31 is fixed on the top surfaces of the two side plate bodies 30. A lifting cylinder 32 is fixed in the middle of the top surface of the upper horizontal plate 31. The bottom end of the push rod of the lifting cylinder 32 extends out of the bottom surface of the upper horizontal plate 31 and is fixed with a lifting plate 33. A second rodless cylinder 34 is fixed on the bottom surface of the lifting plate 33. A transverse pushing block 35 is fixed on the bottom surface of the bottom moving block of the second rodless cylinder 34. The right part of the transverse pushing block 35 extends to the right and is fixed with an anti-collision elastic block 36.

[0024] Furthermore, a plurality of vertical guide rods are fixed on the top surface of the lifting plate 33, and the vertical guide rods are inserted into vertical guiding through holes formed on the upper horizontal plate 31.

[0025] Furthermore, an infrared emitter 3 and an infrared receiver 4 are respectively fixed on the inner side walls at the right sides of the two side plate bodies 30. The infrared emitter 3 emits infrared rays to the infrared receiver 4, and the infrared emitter 3 and the infrared receiver 4 are close to the left end of the placement housing 21.

[0026] All cylinders in this embodiment are connected to a control valve communicated with an air pump of a pneumatic system through a connecting pipe, and the air pump, the control valve, the rotary servo motor 15, the infrared emitter 3, the infrared receiver 4 and all electric rollers 12 are electrically connected to a control host through electric connection lines and are controlled to operate by the control host. This is a conventional structure and will not be elaborated here.

[0027] When this embodiment is in use, the battery module is placed on the electric roller 12 at the left part of the conveying rack 10. As the electric roller 12 runs, it is conveyed to the right. When its right end is between the infrared emitter 3 and the infrared receiver 4, the infrared ray is blocked and cannot be received by the infrared receiver 4. The infrared receiver 4 transmits the induction signal to the control host, and the control host controls the corresponding control valve of the pneumatic system to operate, so that the push rod of the lifting cylinder 32 pushes, and the lifting plate 33 is lowered. Then, the bottom moving block of the second rodless cylinder 34 moves to the right, so that the anti-collision elastic block 36 moves to the right and presses against the left side wall of the battery module, and pushes it into the placement groove 22 until it leans against the pushing block 25. Then, the bottom moving block of the second rodless cylinder 34 returns to its original position (this process takes 5 to 10 seconds), and the lifting plate 33 is lifted back to its original position. That is, after 5 to 10 seconds, the rotary servo motor 15 operates to rotate the placement housing 21 by 180 degrees (the rotary servo motor 15 is a servo motor, and its rotation angle can be controlled and fed back to the control host). When rotating again, its convex positioning portion 271 can move the battery assembly in the placement housing 21 out until the top surface of the right plastic protection plate 2 presses against the bottom surface of the placement housing 21 at this time. That is, after the rotating shaft of the rotary servo motor 15 rotates 180°, the control host controls the moving block of the rodless cylinder 23 to move, so that the pushing block 25 pushes the battery module out of the placement groove 22 to the right. When pushing, it moves along the inclined end surface of the convex positioning portion 271, retracts it into the through hole, and pushes the battery module to the electric roller 12 at the right part of the conveying rack 10 to realize its continuous conveying to the right. At this time, the battery module is flipped 180 degrees so that the bottom surface faces up to meet the needs of subsequent processing.

[0028] After the whole process is completed, the subsequent battery modules will move to the two side plate bodies 30 for continuous conveying and processing. The whole use effect is good, the efficiency is high, the automation degree is high, and there is no need for manual mid-course flipping, greatly reducing the manual labor intensity.
