[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figures 1 to 5 As shown, the embodiment of the utility model provides a cylindrical battery flexible batch material removal and transplanting mechanism 10, which includes a mounting frame 100, a driving assembly 200, a driving shaft 300 and a grabbing assembly 400; the driving shaft 300 is provided with a guide groove 310, the guide groove 310 extends along the outer circumferential wall of the driving shaft 300 and the projection path is a variable pitch spiral line, and the driving shaft 300 is rotatably connected to the mounting frame 100; the driving assembly 200 is connected to the mounting frame 100, and the driving assembly 200 is used to drive The driving shaft 300 rotates relative to the mounting frame 100; the grabbing assembly 400 includes a moving frame 410, a guide member 420 and a grabbing member 430, the moving frame 410 is movably connected to the mounting frame 100, the grabbing member 430 is connected to the moving member and is used to grab the battery 20, the guide member 420 is connected to the moving frame 410, and the guide member 420 is slidably matched with the guide groove 310; when the driving shaft 300 rotates, the moving frame 410 moves relative to the mounting frame 100 along the axial direction of the driving shaft 300.

[0032] In the cylindrical battery flexible batch material removal and transplanting mechanism 10 of the present embodiment, by setting the guide groove 310 distributed in a variable torque spiral line to cooperate with the grabbing assembly 400, when the driving shaft 300 rotates, the grabbing assembly 400 can be driven to move relative to the mounting frame 100. The overall structure is compact, the operation is stable, and the use effect is good.

[0033] Furthermore, the number of grabbing components 400 and guide grooves 310 are both multiple groups, and the grabbing components 400 and guide grooves 310 are connected one-to-one; the movable frame 410 is slidably connected to the mounting frame 100 through a linear slide rail 110; the projections of the multiple guide grooves 310 on the outer circumferential wall of the driving shaft 300 are uniformly diffused.

[0034] In this embodiment, by setting multiple groups of guide grooves 310 to cooperate with multiple groups of grabbing components 400, when the driving component 200 drives the driving shaft 300 to rotate, multiple groups of grabbing components 400 can be driven to move relative to the mounting frame 100 at the same time. In this way, when each group of grabbing components 400 grabs a battery 20, multiple batteries 20 can be moved at the same time to a preset position. Since the multiple groups of guide grooves 310 in this embodiment are arranged in a diffuse shape, the axial movement speed of the grabbing components 400 along the driving shaft 300 is non-uniform in the process of simultaneously driving multiple batteries 20 to move toward or away from each other. Figure 5 In the embodiment shown, the grasping component 400 accelerates in the process of moving away from other grasping components 400, and decelerates in the reverse direction. With this arrangement, the multiple batteries 20 can be separated faster in the direction away from each other and slowly approach each other, thereby not only improving the separation speed of the multiple batteries 20, but also reducing the movement stability of the multiple batteries 20 when they are close to each other.

[0035] In one embodiment, the moving frame 410 includes a first connecting portion 411, a second connecting portion 412 and a moving portion 413, the guide member 420 is connected to the moving portion 413, the first connecting portion 411 and the second connecting portion 412 are respectively connected to the moving portion 413, and the mounting frame 100 is located between the first connecting portion 411 and the second connecting portion 412; the linear slide rail 110 includes a track 111 and a slider 112, the track 111 is connected to the mounting frame 100, wherein at least two sliders 112 are respectively connected to the first connecting portion 411 and the second connecting portion 412, and the slider 112 is slidably matched with the track 111, the second connecting portion 412 is spaced apart from the mounting frame 100, and the track 111 is located between the second connecting portion 412 and the mounting frame 100; the slider 112 of the adjacent grabbing assembly 400 can be accommodated between the second connecting portion 412 and the mounting frame 100.

[0036] Thus, the first connection part 411, the second connection part 412 and the moving part 413 are connected and combined to form a C-shaped structure, and the mounting frame 100 is located between the first connection part 411 and the second connection part 412. At this time, the first connection part 411 and the second connection part 412 are respectively connected to the linear slide rail 110, so that the movement stability of the grab assembly 400 can be improved and the force can be evenly applied. In addition, by setting the second connection part 412 to be spaced apart from the mounting frame 100, since the diameter of the battery 20 is usually smaller than the width of the slider 112, in the process of two adjacent grab assemblies 400 approaching each other, the second connection part 412 can avoid the track 111 and the slider 112 in another group of grab assemblies 400, so that the combined structure of the grab assemblies 400 can be made more compact in the process of multiple grab assemblies 400 approaching each other, and at the same time, the motion interference between the two adjacent groups of grab assemblies 400 can be avoided.

Of course, in other embodiments, the gripping member 430 can also be a mechanical clamp, which is not limited here.

[0039] Furthermore, the grabbing portion 431 defines a receiving groove 4312 , and the magnetic attraction member 432 is received in the receiving groove 4312 .

[0040] With this arrangement, the combined structure of the magnetic element 432 and the grabbing portion 431 can be made more compact, so that the grabbing assembly 400 has a smaller occupied space.

[0046] In this embodiment, by setting a driving wheel 222 connected to the driving motor 210, the driving motor 210 can drive the driving wheel 222 to rotate and drive the driven wheel 223 to rotate through the transmission belt 221. At this time, the driven wheel 223 can drive the driving shaft 300 to rotate; when the diameters of the driving wheel 222 and the driven wheel 223 are different, speed control can also be achieved; in other embodiments, the transmission mechanism 220 can also be a gear transmission structure, which is not limited here.
