[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of the present invention, not all of them. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work all belong to the protection scope of the present invention. The experimental methods in the following embodiments are conventional methods unless otherwise specified. The materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0024] like Figure 1-Figure 5 As shown, the utility model provides a battery busbar automatic riveting device, including a body 1, a busbar 9 having a plurality of bending parts 91, a through hole 92 is provided on the bending part 91, a riveting machine 7 is provided on the body 1, a support member 2 is provided just below the riveting head of the riveting machine 7, a plurality of grooves 21 for accommodating the bending parts 91 are provided on the support member 2, a bottom surface of the inner wall of the groove 21 is provided with a bottom groove 22 for accommodating a nut, and the automatic riveting device also includes a fixing structure 8 and a protective mechanism 5;

[0025] The fixing structure 8 fixes the busbar 9 so that it is stably placed on the support 2;

[0026] The fixing structure 8 can be fixed by two clamping plates to clamp the busbar 9. Here, the fixing structure 8 can be a support rod (such as Figure 3 As shown), the busbar 9 is supported by the support rod, and the support member 2 supports the bent portion 91, so that the busbar 9 can be stably supported and fixed;

[0027] The protection mechanism 5 includes a discharge cylinder 52, a receiving cylinder 53, a driving motor (not shown) and a protection film 55. The discharge cylinder 52 is wound with the protection film 55. The protection film 55 passes through one end between the pressure riveting head and the support member 2 and is fixed to the receiving cylinder 53. When the driving motor drives the receiving cylinder 53 to rotate, the protection film 55 is wound.

[0028] When in use, first place the nut in the bottom groove 22 of the support 2, then place the bent portion 91 of the busbar 9 in the groove 21, and support the busbar 9 through the fixing structure 8, so that the busbar 9 is stably placed on the support 2. At this time, the protective film 55 is between the busbar 9 and the rivet head, and then drive the rivet machine 7 to drive the rivet head to perform rivet work. Due to the presence of the protective film 55, the rivet head will not directly contact the busbar 9, thereby avoiding damage to the busbar 9 caused by the rivet head;

[0029] During the subsequent continuous riveting process between the busbar 9 and the nut, the receiving barrel 53 can be driven to rotate so as to reel in the used protective film 55 with traces of the rivet head, so that there is always a new protective film 55 between the rivet head and the busbar 9 during the subsequent riveting process, thereby preventing a certain area of ​​the protective film 55 from being damaged by continuous squeezing, thereby avoiding damage to the busbar 9.

[0030] like Figure 2 As shown, a limiting assembly 6 is provided on the support plate 51 to limit the position of the discharge cylinder 52;

[0031] Ensure that when the receiving drum 53 is rolling up the protective film 55, the discharging drum 52 can release the protective film 55 of the same length, avoid the protective film 55 on the discharging drum 52 being pulled out too much, avoid wasting the protective film 55, and avoid too much protective film 55 being pulled out and contaminated by impurities in the air, thereby avoiding impurities from contaminating the busbar 9.

[0032] Specifically, it is set here that the discharge cylinder 52 passively follows the rotation of the protective film 55 when it is rolled up, and the receiving cylinder 53 is actively driven to rotate by the driving motor. The limit assembly 6 is located directly above the discharge cylinder 52. The limit assembly 6 includes a slide rail 61, and the slide rail 61 is arranged on the support plate 51. A slide plate 62 is slidably arranged on the slide rail 61. A pressure wheel 63 is rotatably arranged at the bottom end of the slide plate 62, and the pressure wheel 63 abuts against the protective film 55 on the discharge cylinder 52.

[0033] When in use, the pressure wheel 63 and the slide plate 62 will always be in contact with the protective film 55 due to their own weight. There is no need for external force to act on the pressure wheel 63 and the discharge barrel 52. The gravity of the pressure wheel 63 and the slide plate 62 squeezes the protective film 55, so that the discharge barrel 52 can rotate with damping. When the driving motor drives the receiving barrel 53 to rotate, the discharge barrel 52 will not be driven to rotate too much due to the winding of the protective film 55, thereby avoiding excessive discharge of the protective film 55, thereby avoiding waste and preventing impurities from contaminating the busbar 9.

[0034] In addition, the discharging drum 52 and the receiving drum 53 can also be arranged to be actively driven to rotate by a driving motor, that is, when one driving motor drives the receiving drum 53 to rotate and rewind the protective film 55, the other driving motor drives the discharging drum 52 to discharge the material synchronously, which can also avoid excessive discharge of the protective film 55.

[0035] like Figure 1 , Figure 3 and Figure 5 As shown, a vibrating material tray 11 and a clamping and feeding mechanism 3 are provided on the machine body 1. The discharge end of the vibrating material tray 11 is connected to the discharge channel. The clamping and feeding mechanism 3 clamps and fixes the nut on the discharge channel and places it in the bottom groove 22.

[0036] The clamping feeding mechanism 3 can automatically pick up the nuts on the discharge channel connected to the vibrating material tray 11, thereby completing the automatic feeding of the nuts and avoiding the trouble of manually aligning the nuts one by one with the bottom groove 22, thereby improving work efficiency.

[0037] like Figure 1 , Figure 3 and Figure 5 As shown, the machine body 1 is provided with an adjustment mechanism 4, the adjustment mechanism 4 is provided with a support platform 10, the support platform 10 is detachably connected with a support member 2, so that different support members 2 can be replaced according to different busbars 9, and the adjustment mechanism 4 drives the support platform 10 to move to one side of the clamping and feeding mechanism 3;

[0038] The support platform 10 is driven to move to one side of the clamping and feeding mechanism 3 by the adjusting mechanism 4, so as to facilitate the subsequent clamping and feeding mechanism 3 to take the nut out of the discharge channel and place it in the bottom groove 22 on the support member 2;

[0039] The adjustment mechanism 4 here can be set as a transmission structure such as a motor screw or a cylinder.

[0040] like Figure 1 , Figure 3 and Figure 5 As shown, specifically, the clamping and feeding mechanism 3 includes a clamping assembly and a driving member, the clamping assembly clamps and fixes the nut, and the driving member drives the clamping assembly to move, so that the nut is conveyed to the bottom groove 22 on the support member 2;

[0041] Here, the driving member is set as a motor, and the clamping assembly is an existing common clamping structure, which will not be described in detail. After the support table 10 (support member 2) is transported to one side of the clamping and feeding mechanism 3 through the adjustment mechanism 4, the driving member drives the clamping assembly to rotate, so that the nut is clamped from the discharge channel and then rotated and placed in the bottom groove 22 of the support member 2;

[0042] A plurality of bottom grooves 22 can be provided on the support member 2, and the support member 2 can be driven to move by the adjusting mechanism 4 so that a nut is placed in each bottom groove 22. Meanwhile, during the subsequent riveting process, the support member 2 can also be driven to move by the adjusting mechanism 4 so that one riveting head can perform riveting work on a plurality of riveting positions in sequence.

[0043] like Figure 1 and Figure 2 As shown, the protection mechanism 5 includes a support plate 51 disposed on the riveting machine 7, a discharging cylinder 52 and a receiving cylinder 53 are both rotatably disposed on the support plate 51, a plurality of guide wheels 54 are also disposed on the support plate 51, a protection film 55 is in contact with the outer wall of the guide wheel 54, and the height position of the guide wheel 54 is higher than the height position of the top surface of the support member 2;

[0044] Two guide wheels 54 are provided here, which are respectively located on both sides of the riveting machine 7. Since the two guide wheels 54 are at the same height, the protective film 55 between the two guide wheels 54 is parallel to the top surface of the support 2, and the height position of the guide wheel 54 is higher than the height position of the top surface of the support 2, thereby ensuring that when the riveting machine 7 is not in riveting operation, the protective film 55 will not directly contact the support 2 and the busbar 9, so that when the protective film 55 is rolled up, the protective film 55 will not be dragged by the busbar 9, preventing the busbar 9 from falling from the support 2.

[0045] Here, the protective film 55 can be selected as release paper.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
