DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0032] Combine the following Figures 1 to 6 The power battery module flipping device of the present invention is described.

[0033] like Figures 1 to 6 As shown, the present invention provides a power battery module flipping device, including a frame 1, a base 2, a support seat 3 and a lifting device 4, the support seat 3 is rotatably connected to the base 2, the lifting device 4 is arranged on the frame 1, and the lifting device 4 is connected to the support seat 3 to drive the support seat 3 to rotate.

[0034] Specifically, during work, the staff stands on the side of the support seat 3 to process the edge portion of the power battery module workpiece 8. When the middle portion of the power battery module workpiece 8 needs to be processed, the lifting device 4 drives the support seat 3 to rotate, and the power battery module workpiece 8 on the support seat 3 will also rotate accordingly. The support seat 3 will rise as a whole, and the staff can process the middle portion of the power battery module workpiece 8. In this way, when processing a larger power battery module workpiece 8, the staff can process the entire power battery module workpiece 8, which is more convenient to operate and effectively improves the processing efficiency of the power battery module workpiece 8.

[0035] For the convenience of explanation, in this embodiment, each direction is as follows Figure 1 As shown, the first direction is the left-right direction, and the second direction is the front-back direction.

[0036] In some embodiments, a first rotating shaft 31 and a second rotating shaft 32 are provided at the bottom of the support seat 3, and the first rotating shaft 31 and the second rotating shaft 32 both extend in the first direction, and the first rotating shaft 31 and the second rotating shaft 32 can be detachably connected to the base 2. Specifically, the first rotating shaft 31 and the second rotating shaft 32 both extend in the left-right direction, and the first rotating shaft 31 is located at the rear side of the second rotating shaft 32. It can be understood that staff can stand on the front and back sides of the support seat 3 for processing. When the staff on the rear side performs processing, the second rotating shaft 32 is separated from the base 2, and the support seat 3 can rotate backward around the first rotating shaft 31. When the staff on the front side performs processing, the first rotating shaft 31 is separated from the base 2, and the support seat 3 can rotate forward around the second rotating shaft 32. The operation is more convenient and the work efficiency is higher.

[0037] In some embodiments, there are two lifting devices 4, one of which is used to drive the support base 3 to rotate around the first rotation axis 31, and the other lifting device 4 is used to drive the support base 3 to rotate around the second rotation axis 32. By setting two lifting devices 4, the working efficiency is higher.

[0038] In some embodiments, the lifting device 4 includes a transmission motor 41, a lifting mechanism 42 and a displacement mechanism 43. The lifting mechanism 42 and the displacement mechanism 43 are both connected to the transmission motor 41. The lifting mechanism 42 includes a lifting sprocket 421, a lifting chain 422, a lifting bracket 423 and a counterweight block. There are two lifting brackets 423, one of which is arranged on the frame 1, and the other lifting bracket 423 is arranged on the displacement mechanism 43. Both lifting brackets 423 are provided with a lifting sprocket 421. The lifting chain 422 is wound around the two lifting sprockets 421. One end of the lifting chain 422 is connected to the support seat 3, and the other end of the lifting chain 422 is connected to the counterweight block. The transmission motor 41 is connected to the lifting sprocket 421.

[0039] Specifically, the frame 1 includes a vertical pole 11 and a top seat 12. The top seat 12 is arranged at the top of the vertical pole 11, and the counterweight block is located inside the vertical pole 11. The overall appearance is more beautiful. When the front side of the support seat 3 needs to be lifted, the transmission motor 41 is started, and the transmission motor 41 drives the lifting sprocket 421 to rotate, thereby driving the lifting chain 422 to move backward, and the counterweight block descends, driving the front side of the support seat 3 and rotating around the first rotating shaft 31. The transmission motor 41 simultaneously drives the displacement mechanism 43 to drive the lifting bracket 423 to move backward, thereby completing the rotation of the support seat 3, that is, completing the rotation of the power battery module workpiece 8, so that the staff located at the rear side can process the middle part of the power battery module workpiece 8, which is more convenient to operate and has higher work efficiency.

[0040] In some embodiments, the displacement mechanism 43 includes a displacement gear 431, a displacement rack 432, a displacement seat 433 and a displacement guide rail 434. The displacement guide rail 434 and the displacement rack 432 are both arranged on the frame 1. The displacement guide rail 434 and the displacement rack 432 both extend along the second direction, and the second direction is orthogonal to the first direction. The displacement seat 433 is slidably connected to the displacement guide rail 434, and the lifting motor is arranged on the displacement seat 433. One of the lifting brackets 423 is arranged on the displacement seat 433. The transmission motor 41 is connected to the displacement gear 431, and the displacement gear 431 is engaged with the displacement rack 432. Specifically, when the transmission motor 41 is working, it can drive the lifting sprocket 421 and the displacement gear 431 to rotate at the same time. While completing the lifting work, it can also drive the lifting bracket 423 to move, ensuring that the counterweight block can move down and drive the support seat 3 to flip upward, which is more efficient.

[0041] In some embodiments, the base 2 is provided with a locking device 5, which includes a locking cylinder 51, a locking seat 52 and a locking block 53. The locking seat 52 is provided with a supporting groove 54. The locking cylinder 51 is provided on the base 2. The locking cylinder 51 is connected to the locking block 53 to drive the locking block 53 to move toward the supporting groove 54. Specifically, locking devices 5 are provided on the front and back sides of the base 2, one of which is used to lock the first rotating shaft 31, and the other is used to lock the second rotating shaft 32. The supporting groove 54 is used to support the first rotating shaft 31 or the second rotating shaft 32. The locking cylinder 51 drives the locking block 53 to move toward the supporting groove 54, thereby preventing the first rotating shaft 31 or the second rotating shaft 32 from leaving the supporting groove 54, thereby achieving a better fixing effect and a more stable structure.

[0042] In some embodiments, the supporting groove 54 is semicircular in shape, which can lock the first rotating shaft 31 or the second rotating shaft 32 without affecting the rotation of the first rotating shaft 31 or the second rotating shaft 32 .

[0043] In some embodiments, the locking block 53 is provided with a locking groove 55, and the locking seat 52 is provided with an avoidance hole 56. The locking block 53 can be inserted into the avoidance hole 56 to limit the first rotating shaft 31 and the second rotating shaft 32 from leaving the locking groove 55. Specifically, the shape of the locking groove 55 is similar to a U-shape, and the upper side of the locking block 53 is shorter than the lower side of the locking block 53. The first rotating shaft 31 or the second rotating shaft 32 can enter the locking groove 55 from above. After the locking block 53 is inserted into the avoidance hole 56, the locking groove 55 is closed, and the first rotating shaft 31 or the second rotating shaft 32 cannot leave the supporting groove 54 and the locking groove 55, thereby completing the fixation of the first rotating shaft 31 or the second rotating shaft 32. The fixing effect is better and the structure is more stable. While locking the first rotating shaft 31 or the second rotating shaft 32, it will not affect the rotation of the first rotating shaft 31 or the second rotating shaft 32.

[0044] In some embodiments, the base 2 is provided with a lifting device 6, the lifting device 6 includes a lifting cylinder 61 and a lifting rod 62, a support shaft 33 is provided at the bottom of the support seat 3, the lifting cylinder 61 is provided on the base 2, one end of the lifting rod 62 is rotatably connected to the base 2, and the other end of the lifting rod 62 can be clamped on the support shaft 33, the lifting cylinder 61 is connected to the lifting rod 62 to drive the lifting rod 62 to rotate. Specifically, a lifting groove 63 is provided at the end of the lifting rod 62. After the support seat 3 is lifted, the lifting cylinder 61 is used to drive the lifting rod 62 to rotate, so that the lifting rod 62 rotates, and the lifting groove 63 is clamped on the support shaft 33, which can prevent the support seat 3 from falling, improve the fixing effect, and have higher safety.

[0045] In some embodiments, the support seat 3 is provided with a conveying device 7, which conveys the power battery module workpiece 8 along a first direction. The conveying device 7 includes a conveying motor 71, a conveying roller 72 and a conveying transmission member. The conveying motor 71 is provided on the support seat 3, and the conveying roller 72 is rotatably connected to the support seat 3. The conveying motor 71 is connected to the conveying roller 72 through the conveying transmission member, and can smoothly convey the power battery module workpiece 8.

[0046] In some embodiments, the conveying transmission member is a sprocket chain structure.

[0047] The present invention also provides a power battery module flipping method, which uses the above-mentioned power battery module flipping device and includes the following steps:

[0048] S1. A worker stands on the side of the support seat 3 to process the edge of the power battery module workpiece 8;
