[0026] In order to enable persons skilled in the art to better understand the technical solutions in the present application, the technical solutions in the present application will be clearly and completely described below in conjunction with embodiments.

[0027] like Figure 1-Figure 3 As shown, the utility model discloses a positioning device before welding of a pole lug, comprising a frame 1, on which a top three-axis device 2 and a side three-axis device 3 are arranged, a top positioning device 4 is movably arranged on the top three-axis device 2, and a side positioning device 5 is arranged on the side three-axis device 3; a lifting positioning rotating device 6 is also arranged beside the frame 1;

[0028] In this patent, the top three-axis device 2 is mainly used to drive the top positioning device 4 to move in the X, Y, and Z axis directions to facilitate the coordinate collection of the pole ears on the battery cell assembly; similarly, the side three-axis device 3 is mainly used to drive the side positioning device 5 to move in the X, Y, and Z axis directions; this positioning device is mainly suitable for the positioning of the pole ears of two different battery cell assemblies, one is that the pole ears are set on the top of the battery cell assembly, and the other is that the pole ears are set on the side of the battery cell assembly.

[0029] like Figure 4-Figure 6 As shown, the lifting, positioning and rotating device 6 includes a first support plate 7, on which are mounted two symmetrically arranged lifting and positioning cylinders 8 and a rotating motor 9, a second support plate 10 is fixed to the output end of the lifting and positioning cylinder 8, a rotating hollow platform 11 is arranged on the second support plate 10, the bottom of the rotating hollow platform 11 is connected to a reducer 12, the reducer 12 is connected to the rotating motor 9, a positioning platform 13 is connected to the top of the rotating hollow platform 11, and the positioning platform 13 rotates along with the rotating hollow platform 11 under the drive of the rotating motor 9.

[0030] In the technical solution, the middle of the first support plate 7 is hollowed out to facilitate the up and down movement of the rotating motor 9 and the reducer 12 on the first support plate 7. The reducer 12 is connected to the bearing of the rotating hollow platform 11. The rotating hollow platform 11 is driven by the rotating motor 9 to rotate, and then the positioning platform 13 on the rotating hollow platform 11 is driven to rotate to weld the side pole ears of the battery cell assembly. The rotating hollow platform 11 in this patent is a purchased standard part and is not described in detail here.

[0031] The positioning platform 13 is provided with a positioning pin 14 , and the positioning pin 14 is used in conjunction with a positioning hole on the tooling to position the tooling tray.

[0032] like Figure 7 As shown, the output end of the lifting and positioning cylinder 8 is connected to the second support plate 10 through a floating joint 15. The lifting and positioning cylinder 8 lifts the device on the second support plate 10 together, that is, lifts the tooling pallet together above the speed chain to avoid interference during the rotation process, and at the same time plays a role of lifting and lowering. The application of the floating joint 15 ensures the stability of the equipment operation and reduces errors.

[0033] The second support plate 10 moves up and down on the first support plate 7 through the guide sleeve 16 and the guide column 17, thereby ensuring the stability of the operation of the second support plate 10.

[0034] like Figure 8 As shown, the top positioning device 4 includes a camera module 401 movably arranged on the vertical module, and the camera module 401 can move up and down on the vertical module.

[0035] A light source module 402 is disposed below the camera module 401, and the light source module 402 includes a group of symmetrically disposed light sources 4021. The light source 4021 is used to illuminate the camera when taking pictures.

[0036] The light source 4021 is disposed on the connecting plate 4023 via a connecting frame 4022 .

[0037] The two ends of the light source 4021 are movably connected to the two ends of the connecting frame 4022 through angle iron pieces 4024 respectively.

[0038] like Fig. 9 As shown, the angle iron piece 4024 is connected to the connecting frame 4022 through an arc hole 4025, and the two arc holes 4025 are locked by bolts and screws. By setting concentric arc holes, the angle and position of the light source 4021 can be adjusted according to the needs of use. When in use, loosen the bolts and screws, manually adjust the angle of the light source 4021, and after adjustment, tighten the bolts and screws to fix the angle of the light source.

[0039] The structure of the side positioning device 5 is the same as that of the top positioning device 4, but the setting position is different, which will not be described here.

[0040] The top three-axis device 2 and the side three-axis device 3 in this patent adopt a conventional three-axis setting, that is, a module that can realize operation in the X, Y, and Z axis directions, which will not be described in detail here.

[0041] The tooling pallet (not shown in the figure) of this patent is transported to the pre-welding positioning station by the double-speed chain (not shown in the figure). After the proximity switch detects that the tooling pallet is in place, the lifting and positioning rotating device below lifts and positions the tooling pallet. After the lifting is completed, the RFID (not shown in the figure) reads the pallet. Pre-welding positioning uses different three axes for different machine models. For top positioning, the top three-axis device is used to drive the camera to locate the pole ear, mainly to locate the relative coordinates of the pole ear. After the positioning is completed, the three axes return to the origin, the lifting and positioning descends, and the blocking cylinder releases the pallet. For side positioning, the side three axes are used to drive the camera to locate the weld of the pole ear, mainly to locate the relative coordinates of the pole ear. After the positioning is completed, the three axes return to the origin, the lifting and positioning descends, and the blocking cylinder releases the pallet. For the battery cell assembly with the pole ear at the top, the lifting and positioning rotating device only performs the lifting and positioning action; for the battery cell assembly with the pole ear at the side, the lifting and positioning rotating device also performs the rotation action.

[0042] The described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of 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.
