Description

Technical Field

[0001] This utility model relates to the field of battery equipment technology, and in particular to a tab production line and conveying equipment. Background Technology

[0002] Currently, in the production process of electrode tabs, conveying is achieved using idler rollers. These idler rollers have a follower structure with several teeth for contacting the sealant (or electrode tab adhesive). The electrode tab belt and sealant are intermittently conveyed forward, with the sealant contacting the teeth on the idler roller and causing it to rotate. The idler rollers are free-rotating and relatively loose, allowing the sealant to contact the roller teeth and rotate. However, due to inertia, the roller's rotation causes the roller teeth to detach from the sealant, making it easy for the edge of the electrode tab belt to rub against the roller teeth during conveying, thus affecting the quality of the electrode tab belt. Utility Model Content

It is understood that this specification should be regarded as an exemplary illustration of the principles of the present invention and is not intended to limit the present invention to what is described herein.

[0031] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0032] In the embodiments shown in the accompanying drawings, the directional indications (such as up, down, left, right, front, and back) used to explain the structure and movement of the various elements of this invention are relative rather than absolute. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, these directional indications also change accordingly.

[0033] This application provides a conveying device, mainly used for conveying electrode straps and sealant.

[0034] Combination Figures 1-3The conveying device includes a rotating shaft 11, an idler roller 12, and at least one positioning assembly. The idler roller 12 is sleeved on the outer periphery of the rotating shaft 11 and is rotatable relative to the rotating shaft 11. The positioning assembly includes a positioning block 132 sleeved on the rotating shaft 11 and spaced at the axial end of the idler roller 12, a first positioning element 131 disposed at the end of the idler roller 12, and a second positioning element 133 disposed on the positioning block 132. The first positioning element 131 and the second positioning element 133 are magnetically attracted to each other to achieve circumferential positioning of the idler roller 12.

[0035] The magnetic attraction between the first positioning element 131 and the second positioning element 133 ensures that when the idler roller 12 stops rotating, the first positioning element 131 corresponds exactly to the second positioning element 133, thereby avoiding the inertial rotation of the idler roller 12, thus preventing rubbing or even scratching the sealant 3 and ensuring the quality of the electrode ear belt 2.

[0036] Specifically, the idler roller 12 includes a cylinder 121 sleeved on the outer periphery of the rotating shaft 11 and a plurality of roller teeth 122 protruding outward from the outer periphery of the cylinder 121.

[0037] The axis of the cylinder 121 is parallel to the axis of the rotating shaft 11, and both ends of the rotating shaft 11 extend outward beyond the two ends of the cylinder 121.

[0038] The idler roller 12 and the rotating shaft 11 are rotatably connected by bearings. Specifically, the cylinder 121 is connected to the rotating shaft 11 via bearings.

[0039] Multiple roller teeth 122 protrude from the outer periphery of the cylinder 121, and multiple rollers are evenly arranged along the axial direction of the cylinder 121.

[0040] The idler roller 12 includes multiple sets of roller teeth spaced apart along the axial direction of the cylinder 121, and each set of roller teeth includes multiple roller teeth 122 spaced apart circumferentially along the cylinder 121. The distance between any two adjacent sets of roller teeth is used to accommodate a tab 2.

[0041] The dimensions of the roller teeth 122 along the circumference of the cylinder 121 gradually decrease from near the cylinder 121 to away from the cylinder 121. The four corners of the ends of the roller teeth 122 away from the cylinder 121 are all rounded.

[0042] Among the multiple roller tooth groups on the entire cylinder 121, the roller tooth groups located at both ends of the cylinder 121 in the axial direction are the end roller tooth groups.

[0043] Each roller tooth 122 located at both ends of the cylinder 121 has a receiving hole, that is, each roller tooth 122 of the end roller tooth group has a receiving hole. The axis of the receiving hole is parallel to the axis of the cylinder 121.

[0044] In some embodiments, the receiving hole may also be a receiving groove with an outward opening, where outward refers to the direction toward the corresponding positioning block 132.

[0045] Preferably, the axial length of the roller teeth 122 of the end roller tooth group is greater than the axial length of the roller teeth 122 of the other roller tooth groups, so as to better install the first positioning member 131.

[0046] The positioning components can be disposed at one axial end of the idler roller 12, or at both axial ends of the idler roller 12. In this embodiment, there are two sets of positioning components, arranged at both axial ends of the idler roller 12. That is, positioning components are provided at both axial ends of the idler roller 12.

[0047] The positioning assembly includes a positioning block 132 sleeved on the rotating shaft 11 and spaced at the axial end of the idler roller 12, a first positioning member 131 disposed at the end of the idler roller 12, and a second positioning member 133 disposed on the positioning block 132.

[0048] The positioning block 132 is fixedly connected to the rotating shaft 11. When the conveying equipment is conveying the tab belt 2, the rotating shaft 11 and the positioning block 132 are fixed, while the idler roller 12 rotates relative to the rotating shaft 11 to convey the tab belt 2.

[0049] See Figure 4 The positioning block 132 has a through mounting hole, the axis of which is parallel to the axis of the rotating shaft 11. Specifically, the positioning block 132 has a positioning tooth 134 corresponding to the roller tooth 122, the positioning tooth 134 has a mounting hole, and the second positioning member 133 is disposed in the mounting hole.

[0050] The roller has five teeth 122, therefore, each positioning assembly has five first positioning elements 131, each positioning block 132 has five positioning teeth 134, and each positioning assembly has five second positioning elements 133. When the roller 12 rotates, it rotates until the roller teeth 122 and the positioning teeth 134 correspond one-to-one, and each roller tooth 122 is directly opposite the corresponding positioning tooth 134.

[0051] In some embodiments, the positioning block 132 may not have positioning teeth, and its cross-section is circular, with its outer periphery extending outward to correspond to the roller teeth 122. The second positioning member 133 is directly disposed on the positioning block 132 at the location corresponding to the roller teeth 122.

[0052] At least one of the first positioning element 131 and the second positioning element 133 is a magnetic material. That is, both can be magnetic materials, or one can be a magnetic material and the other can be a metal material.

[0053] In this example, the first positioning element 131 is a magnetic material, and the second positioning element 133 is a metal material, with the magnetic material capable of attracting the metal material. In other embodiments, both the first positioning element 131 and the second positioning element 133 are magnetic materials. Alternatively, the first positioning element 131 is a metal material, and the second positioning element 133 is a magnetic material.

[0054] Magnetic materials refer to substances or materials that can generate magnetic fields. Metallic materials include iron, cobalt, nickel, and their alloys. Iron, cobalt, nickel, and their alloys are ferromagnetic materials, possessing significant magnetism and capable of being attracted by magnets.

[0055] Specifically, in this embodiment, the magnetic body can be a magnet, and the metal part can be made of iron. The magnet generates a magnetic field that attracts iron.

[0056] The first positioning element 131 is disposed in the receiving hole. In this embodiment, the first positioning element 131 is bonded to the peripheral sidewall of the receiving hole, that is, the first positioning element 131 is bonded to the roller tooth 122.

[0057] The second positioning element 133 is disposed in the mounting hole. The second positioning element 133 is screwed to the positioning wheel tooth 134.

[0058] Specifically, the mounting hole has an internal thread on its peripheral sidewall, and the second positioning member 133 has an external thread on its outer periphery. The external thread and the internal thread are adapted to fit together so that the second positioning member 133 is screwed onto the positioning block 132. The second positioning member 133 can adjust the axial distance between itself and the first positioning member 131 through the screw connection.

[0059] The positioning block 132 is provided with at least three turns of internal thread extending helically along the axis of the rotating shaft 11.

[0060] The distance between the first positioning element 131 and the second positioning element 133 is 1~5mm. This distance refers to the axial distance between the first positioning element 131 and the second positioning element 133 along the rotating shaft 11, and specifically the distance between the end face of the first positioning element 131 facing the second positioning element 133 and the end face of the second positioning element 133 facing the first positioning element 131. This distance limitation ensures the magnetic attraction between the first positioning element 131 and the second positioning element 133 while preventing excessive magnetic force that could prevent the idler roller 12 from rotating.

[0061] In summary, this conveying equipment has the following advantages:

[0062] The conveying equipment includes a rotating shaft 11, an idler roller 12, and at least one positioning assembly. The positioning assembly includes a positioning block 132 sleeved on the rotating shaft 11 and spaced at the axial end of the idler roller 12, a first positioning element 131 disposed at the end of the idler roller 12, and a second positioning element 133 disposed on the positioning block 132. The first positioning element 131 and the second positioning element 133 are magnetically attracted to each other to achieve circumferential positioning of the idler roller 12. Through the magnetic attraction between the first positioning element 131 and the second positioning element 133, when the idler roller 12 stops rotating, the first positioning element 131 is precisely aligned with the second positioning element 133, thereby preventing the idler roller 12 from rotating due to inertia, thus preventing rubbing or even scratching the sealant 3, and ensuring the quality of the tab belt 2.

[0063] This utility model also provides a tab production line, including the above-mentioned conveying equipment.
