[0030] The following is combined with Figures 1 to 5 The present invention is described in further detail, but is not intended to limit the present invention.

[0031] like Figure 1 and 2 As shown, in one embodiment of the present invention, the battery clamping and conveying device includes a frame 1, a driving mechanism 2, a swinging traction component 3 and a clamping mechanism 4; the mounting end of the driving mechanism 2 is connected to the frame 1, and the movable end of the driving mechanism 2 is connected to one end of the swinging traction component 3; the swinging traction component 3 is movably connected to the frame 1; the clamping mechanism 4 includes a positioning clamping component 41 and a movable clamping component 42; the positioning clamping component 41 is fixedly connected to the frame 1; one end of the movable clamping component 42 is movably connected to the other end of the swinging traction component 3; and a clamping gap 401 is provided between the positioning clamping component 41 and the movable clamping component 42; the clamping gap 401 is used to clamp the battery body 6.

[0032] The technical solution of the present invention enables the swinging traction component to swing under the driving operation of the driving mechanism, pulling and driving the movable clamping component to adjust toward or away from the positioning clamping component, thereby quickly and stably increasing or decreasing the size of the clamping gap, and thus can adapt to the clamping and conveying of batteries of more different sizes, thereby increasing its diversity of use and improving the smoothness and stability of operation; it can also improve the compactness and rationality of the overall structure.

[0033] Specifically, in some embodiments, Figure 1 and 2 As shown in FIG4 , a support plate 11 is provided at the bottom of the frame 1; an assembly cavity 101 is provided between the support plate 11 and the frame 1; the driving mechanism 2 and the swing traction component 3 are arranged inside the assembly cavity 101; to avoid external impact and other phenomena, thereby improving the protection of the driving mechanism 2 and the swing traction component 3 and improving the compactness and rationality of the overall structure. Figure 4 As shown, a limiting channel 111 is provided in the support plate 11; the other end of the swing traction component 3 passes through the limiting channel 111 and is movably connected to the movable clamping component 42; so as to realize the limiting control function of the swing position of the swing traction component 3, thereby improving the orderliness and stability of the clamping.

[0034] Specifically, in some embodiments, Figure 1 and 2 As shown, the clamping member 41 includes a positioning plate 411; a clamping flat surface is provided on one side of the positioning plate 411 facing the movable clamping member 42; the clamping flat surface is used to abut the battery body 6. This structure, through the positioning plate 411 and its clamping flat surface, ensures clamping stability and smooth loading and unloading of materials, thereby improving clamping and conveying efficiency.

[0035] Specifically, in some embodiments, Figure 1 、 2 As shown in Figures 3 and 4, the drive mechanism 2 includes a height drive cylinder 21 and a mounting block 22. The height drive cylinder 21 is connected to the inner top of the frame 1 and to one end of the mounting block 22. The other end of the mounting block 22 is connected to the swinging and pulling member 3. In other words, the height drive cylinder 21 drives the mounting block 22 to perform a cyclic motion along the vertical direction of the Z axis, thereby causing the swinging and pulling member 3 to perform a cyclic swinging motion, thereby improving the smoothness of the swinging motion and promoting orderly and stable clamping.

[0036] Specifically, in some embodiments, Figure 1 、 2As shown in Figure 3, the swing traction component 3 includes a first positioning column 31 and a swing plate 32. The end of the first positioning column 31 is rotatably connected to the inner wall of the frame 1 (the middle assembly cavity 101). The upper end of the swing plate 32 is movably connected to the driving mechanism 2 (the middle mounting block 22). The lower end of the swing plate 32 (passing through the limiting channel 111) is movably connected to the movable clamping component 42. The side end of the swing plate 32 is movably connected to the outer surface of the positioning column 31. In other words, with the positioning column 31 as the limiting positioning base point, under the up and down driving action of the height driving cylinder 21, the upper end of the traction swing plate 32 swings along the vertical plane, thereby causing the lower end of the traction swing plate 32 to swing and the movable clamping component 42 to clamp. This can adapt to the clamping and conveying of batteries of more different sizes, thereby increasing its diversity of use and improving the smoothness and stability of operation. It can also improve the compactness and rationality of the overall structure.

[0037] Specifically, in some embodiments, Figure 3 and 4 As shown, the swing plate 32 has a mounting groove 321 on one side thereof facing the positioning post 31; the outer surface of the positioning post 31 is limitedly disposed within the mounting groove 321. The mounting groove 321 is an arc-shaped mounting groove; further, the mounting groove 321 is an arc-shaped mounting groove larger than 1 / 2 of a circle; this ensures smooth rotation and limit, and also prevents the swing plate 32 from falling off and being damaged, thereby improving the stability and smoothness of use. Figure 4 As shown, a first mounting hole is provided in the upper end of the swing plate 32; a first positioning movable rod 322 is disposed in the first mounting hole; one end of the first positioning movable rod 322 is connected to the drive mechanism 2 (the middle mounting block 22), thereby simplifying the transmission structure and ensuring smooth rotation. Furthermore, the swing plate 32 is a triangular cross-section swing plate.

[0038] Specifically, in some embodiments, Figure 3 and 4 As shown, both ends of the first positioning column 31 are provided with mounting bearings 313; the mounting bearings 313 are connected to the frame 1; the outer surface of the first positioning column 31 is also provided with a first limiting protrusion 311 and a second limiting protrusion 314; a limiting groove 312 is provided between the first limiting protrusion 311 and the second limiting protrusion 314 and the outer surface of the first positioning column 31; the swing plate 32 is connected to the inside of the limiting groove 312; to prevent the swing plate 32 from rotating and falling off, thereby ensuring the smoothness and stability of the rotation.

[0039] Specifically, in some embodiments, Figure 1 、 2As shown in Figures 3 and 5, a sliding traction member 33 is provided at the bottom of the swinging traction member 3; the sliding traction member 33 is disposed at the bottom of the frame 1 (middle support plate 11); and a movable clamping member 42 is disposed on the sliding traction member 33; and the sliding drive direction of the sliding traction member 33 intersects the drive direction of the drive mechanism 2. The sliding drive direction (Y-axis) of the sliding traction member 33 is perpendicular to the drive direction (Z-axis) of the drive mechanism 2. That is, under the up-and-down drive action of the height drive cylinder 21, the upper end of the traction swing plate 32 swings along a vertical plane, thereby causing the lower end of the traction swing plate 32 to swing and the sliding traction member 33 to slide laterally along the Y-axis, causing the movable clamping member 42 to perform a movable clamping motion. This allows the clamping and conveying of batteries of various sizes to be accommodated, thereby increasing its versatility, improving the compactness and rationality of the overall structure, and enhancing the smoothness and stability of operation.

[0040] Specifically, in some embodiments, Figure 5 As shown, the sliding traction member 33 includes a sliding seat 331 and at least one second positioning post 332; the second positioning post 332 is fixedly connected to the bottom of the frame 1 (middle support plate 11); the sliding seat 331 is sleeved on the outer surface of the second positioning post 332; and the upper end of the sliding seat 331 is movably connected to the bottom of the swing traction member 3 (middle swing plate 32); the lower end of the sliding seat 331 is connected to the movable clamping member 42. There are two second positioning posts 332, which are arranged side by side on the frame 1. That is, when the bottom of the swing plate 32 swings forward, the sliding seat 331 slides along the second positioning post 332, thereby achieving a clamping movement of the movable clamping member 42 toward the positioning clamping member 41. This allows the clamping and conveying of batteries of various sizes to be accommodated, thereby increasing its versatility, improving the compactness and rationality of the overall structure, and enhancing the smoothness and stability of operation. Furthermore, a second mounting hole is provided at the bottom of the swinging traction component 3 (middle swinging plate 32); a connecting block 3311 is provided at the upper end of the sliding seat 331; a mounting groove 3312 is provided in the connecting block 3311; a second positioning movable rod 3313 is provided in the mounting groove 3312; the second positioning movable rod 3313 is movably connected to the inner wall of the second mounting hole; to ensure the stability and orderliness of the swinging motion and the sliding motion; and to improve the compactness and rationality of the overall structure.

[0041] Specifically, in some embodiments, Figure 5As shown, the movable clamping member 42 has a first abutting bevel 421 and a second abutting bevel 422 connected to one another on one side of the clamping gap 401. Both the first abutting bevel 421 and the second abutting bevel 422 are used to abut the battery body 6. This structure, through the first and second abutting bevels 421 and 422, achieves abutment and clamping of the upper and lower portions of the battery body 6, improving the speed and stability of the clamping operation and facilitating material discharge. An assembly gap 424 is provided between the first and second abutting bevels 421 and 422 and the battery body 6 to prevent the battery body 6 from being too tightly pressed against the movable clamping member 42, which could affect the speed and orderliness of material discharge and ensure clamping stability. In some embodiments, the angle α between the first abutting bevel 421 and its horizontal plane is greater than the angle β between the second abutting bevel 422 and its horizontal plane. The angle α satisfies the following conditions: 45°≤α≤60°; and the angle β satisfies the following conditions: 15°≤α≤30°. That is to say, the battery body 6 is scooped up by the second abutting slope 422 with a small inclination, and then the battery body 6 is clamped by the surface of the second abutting slope 422 combined with the first abutting slope 421 with a large inclination, so that fast and stable clamping can be achieved.

[0042] Specifically, in some embodiments, Figure 1 and 2 As shown, the battery clamping and conveying device also includes a storage container 5; a storage cavity 501 is provided in the storage container 5; the storage cavity 501 is connected to the clamping gap 401. In some embodiments, (not shown in the figure) the outer surface of the frame 1 is connected to a power source for three-dimensional movement; the power source includes a height lateral movement drive (Z axis), a horizontal lateral movement drive (Y axis) and a longitudinal lateral movement drive (X axis) that are connected to each other; and placement slots and operation blank stations that are alternately arranged are provided in the storage cavity 501; the placement slot is used to place the battery body 6; the positioning clamping component 41 and the movable clamping component 42 are arranged on two different operation blank stations; to achieve orderliness in loading or unloading and improve operational efficiency. Furthermore, (not shown in the figure) a pushing cylinder is also provided in the storage container 5; the pushing direction of the pushing cylinder is arranged to be consistent with the diameter direction of the placement slot; to achieve transfer between different placement slots, so as to avoid the power source's range of movement being too large and colliding with the storage container 5. Further, as Figure 5 As shown, the bottom of the movable clamping component 42 away from the swinging traction component 33 is provided with a contact bottom straight surface 423; the contact bottom straight surface 423 abuts against the inner bottom of the storage cavity 501; to reduce the damage caused by collision between the two, and plays a certain guiding and driving role.
