[0035] See also Figures 1 to 4 In order to better understand the cylindrical battery roll core transportation distance component 10 of the present application, the cylindrical battery roll core transportation distance component 10 is further explained below:

[0036] The transport distance-fixing assembly 10 of the cylindrical battery roll core of one embodiment includes a driving member 200, a frame 300 and a spiral limit assembly 400. The frame 300 is fixedly installed on one side of the conveyor line. The spiral limit assembly 400 includes a spiral rotating body 410, and the spiral rotating body 410 and the other side of the conveyor line together form a distance-fixing station 401, and the outer peripheral wall of the spiral rotating body 410 is spirally surrounded by a rotation limit groove 4101, and the rotation limit groove 4101 abuts against the outer peripheral wall of the cylindrical positioning fixture 100; the two ends of the spiral rotating body 410 are respectively connected to the frame 300 for rotation, and one end of the spiral rotating body 410 is also connected to the power output shaft of the driving member 200.

[0037] In this embodiment, when the battery roll core and the cylindrical positioning jig 100 on the conveyor line are transported to the distance-fixing station 401, the driving member 200 drives the spiral rotating body 410 to rotate, so that the rotation limit groove 4101 rotates and abuts against the outer peripheral wall of the cylindrical positioning jig 100, so as to push the cylindrical positioning jig 100 from the first predetermined position to the second predetermined position; the driving member 200 stops driving the spiral rotating body 410 to rotate, so that the rotation limit groove 4101 always abuts against the outer peripheral wall of the cylindrical positioning jig 100, so as to form a motion limit for the cylindrical positioning jig 100, thereby effectively improving the distance stopping accuracy of the transportation of the battery roll core and the cylindrical positioning jig 100 without frequently stopping the conveyor line, and effectively solving the problem of tipping over of the battery roll core and the cylindrical positioning jig 100.

[0038] It should be noted that if Figure 1 As shown, in one embodiment, for example, A refers to the first predetermined position, and B refers to the second predetermined position. Specifically, the cylindrical positioning fixture 100 moves linearly from the first predetermined position to the second predetermined position along the direction of the Y arrow.

[0042] It can be understood that in this embodiment, the height of the spiral rotating body 410 on one side of the conveyor line can be adjusted through the mounting plate 310, so that the rotation limit groove 4101 on the outer peripheral wall of the spiral rotating body 410 can better abut against the outer peripheral wall of the cylindrical positioning fixture 100, thereby realizing the rotation of the spiral rotating body 410 to drive the movement of the cylindrical positioning fixture 100, or the spiral rotating body 410 stops rotating to form a motion limit for the cylindrical positioning fixture 100.

[0044] It can be understood that in this embodiment, the two ends of the spiral rotating body 410 are detachably connected to the first connecting shaft 420 and the second connecting shaft 430, respectively, so as to improve the convenience of the spiral rotating body 410 to be installed or removed separately, and also facilitate the maintenance and replacement of the spiral rotating body 410. At the same time, the first bearing member 500 is installed in the first rotating connection hole 3201, and the second connecting shaft 430 is installed in the second rotating connection hole 3301, so as to effectively improve the structural rationality of the rotational connection between the spiral rotating body 410 and the first side plate 320 and the second side plate 330, respectively, and ensure the rotational stability of the spiral rotating body 410.

[0045] like Figures 1 to 3 As shown, in one embodiment, the cylindrical battery roll core transport distance assembly 10 further includes a transmission assembly 700, the transmission assembly 700 includes a transmission belt 710, a first gear member 720 and a second gear member 730, the inner ring of the first gear member 720 is sleeved on the power output shaft of the driving member 200, and the inner ring of the second gear member 730 is sleeved on the outer wall of the other end of the second connecting shaft 430; the inner ring of the transmission belt 710 is sleeved on the outer ring of the first gear member 720 and the outer ring of the second gear member 730. In one embodiment, the first gear member 720 and the second gear member 730 are both plastic structural members.

[0047] like Figure 3 As shown, in one embodiment, the frame 300 also includes an adjustable fixing block 800, and the adjustable fixing block 800 is provided with a first adjustment positioning through hole 801 and a second adjustment positioning through hole 802, and the adjustable fixing block 800 is screwed to the second side plate 330 using screws through the first adjustment positioning through hole 801 and the second adjustment positioning through hole 802 respectively; the driving member 200 is located on the side of the adjustable fixing block 800 away from the second side plate 330, and the driving member 200 is screwed to the adjustable fixing block 800.

[0049] like Figure 4As shown, in one embodiment, the width of the rotation limiting groove 4101 is greater than the outer wall diameter of the cylindrical positioning fixture 100. It is ensured that the rotation limiting groove 4101 and the other side of the transmission line form a motion limit for the cylindrical positioning fixture 100, so as to achieve smooth movement and precise fixed-distance stopping of the cylindrical positioning fixture 100.

[0050] It should be noted that if Figure 4 As shown, C refers to the width of the rotation limiting groove 4101.

[0051] The working principle of the transport and spacing assembly 10 of the cylindrical battery roll core is as follows: first, the battery roll core and the cylindrical positioning fixture 100 are transported to the spacing station 401 by the conveyor line, and the rotation limit groove 4101 rotates and abuts against the outer peripheral wall of the cylindrical positioning fixture 100; secondly, the driving member 200 drives the spiral rotating body 410 to rotate (such as Figure 1 The X arrow in the middle rotates to point to the right), so that the rotation limit groove 4101 pushes the cylindrical positioning fixture 100 to perform a linear motion on the conveyor line (such as Figure 1 Finally, the robot (not shown) completes the grabbing of the battery roll core, and the driving member 200 drives the spiral rotating body 410 to rotate again, so that the rotating limit groove 4101 pushes the cylindrical positioning fixture 100 to perform a linear motion on the conveyor line again, thereby causing the cylindrical positioning fixture 100 to leave the fixed distance station 401.

[0052] The present application also provides a transport distance device for a cylindrical battery roll core, comprising the transport distance assembly 10 for a cylindrical battery roll core described in any of the above embodiments.

[0054] Compared with the prior art, the utility model has at least the following advantages:

[0055] When the battery roll core and the cylindrical positioning jig on the conveyor line are transported to the fixed-distance station, the driving member drives the spiral rotating body to rotate, so that the rotation limit groove rotates and abuts against the outer peripheral wall of the cylindrical positioning jig to push the cylindrical positioning jig from the first predetermined position to the second predetermined position; the driving member stops driving the spiral rotating body to rotate, so that the rotation limit groove always abuts against the outer peripheral wall of the cylindrical positioning jig to form a motion limit for the cylindrical positioning jig, thereby eliminating the need to frequently stop the conveyor line, effectively improving the fixed-distance stopping accuracy of the battery roll core and the cylindrical positioning jig, and effectively solving the problem of tipping over of the battery roll core and the cylindrical positioning jig.
