[0082] An application method of a high-speed and high-efficiency sealing nail welding device comprises the following steps:

[0083] In step S1, a plurality of batteries 17 are grabbed and moved by a feeding mechanism to a carrier 16 of a feeding return line;

[0084] In step S2, the plurality of batteries 17 are moved to the work station of the cleaning assembly 3, positioned to the battery 17 liquid injection hole on the basis of the cleaning reference table, and the impurities around the battery 17 liquid injection hole are cleaned by the laser cleaning mechanism.

[0085] Step S3: After the cleaning component 3 is completed, the batteries 17 are transferred to the nailing component 4 through the feeding return line. After the nailing detection mechanism positions the batteries 17, the sealing nails are accurately placed into the injection holes of the corresponding batteries 17 through the nailing mechanism.

[0086] Step S4: After the battery cells 17 are nailed to the assembly station 4, they are transferred to the welding assembly station via the feeding reflow line. The pre-welding mechanism uses the pre-welding detection mechanism to accurately position the sealing nails of the battery 17 injection hole. After positioning, the pre-welding laser output unit 28 performs pre-welding processing;

[0087] In step S5, after the pre-welding operation of the plurality of batteries 17 is completed, the plurality of batteries 17 on the same carrier 16 are sequentially transported to the workstations of the first welding mechanism 6, the second welding mechanism 7, the third welding mechanism 8, and the fourth welding mechanism 9 through the feeding reflow line. The first welding mechanism 6, the second welding mechanism 7, the third welding mechanism 8, and the fourth welding mechanism 9 sequentially weld the unwelded batteries 17 on the carrier 16. After the carrier 16 is laser-welded by the fourth welding mechanism 9, all the batteries 17 on the carrier 16 are welded, completing the welding process of all the batteries 17 on one carrier 16 at the welding assembly workstation.

[0088] Step S6: After welding, the plurality of batteries 17 are transported to the NG nail removal mechanism 10 station through the feeding return line. The NG nail removal mechanism 10 collects the NG sealing nails in the plurality of batteries 17 detected at the welding assembly station.

[0089] Step S7, after the battery 17 is completed at the NG nail removal mechanism 10 station, several batteries 17 are sequentially transported to the 3D inspection unit and the 2D inspection unit through the feeding return line. If they pass, the battery 17 is taken to the qualified product area through the unloading mechanism. If they fail, the unqualified battery 17 is placed in the unqualified product area 15 through the unloading mechanism.

[0090] The working principle of this utility model:

[0091] In this embodiment, the carrier 16 that can accommodate batteries 17 moves clockwise along the feeding return line, first being transported to the side of the feeding assembly through the feeding belt 1. The feeding assembly, cleaning assembly 3, nailing assembly 4, welding assembly, rejection assembly, and detection assembly are arranged in sequence clockwise along the feeding return line. Therefore, the batteries 17 on the carrier 16 are processed in sequence by the cleaning assembly 3, nailing assembly 4, welding assembly, rejection assembly, detection assembly, and the station where the unloading assembly is located, and then moved to the unloading belt 14 for output. In addition, there is also a waiting area 13 and a failed product area 15. In this embodiment, a qualified product area can also be set or qualified products can be directly sent out, which is not shown in the drawings. Furthermore, a transfer mechanism and a matching mechanism can be set to help with the classification of loading or unloading.

[0092] The loading mechanism and unloading mechanism are respectively set on the front and rear end surfaces of the material rack 2 to save space. The loading clamp 221 and the unloading clamp 211 can use the same clamp structure. A clamping pad can be set on the inner side of the clamp structure to prevent the battery 17 from slipping. The part of the clamp structure that contacts the battery 17 is made of non-metallic insulating material, and the opening and closing of the clamp is controlled by the solenoid valve assembly. In addition, the clamp structure can be provided with a battery 17 position sensor to detect whether the battery 17 is grasped. Both the loading mechanism and the unloading mechanism can move along the X-axis direction, that is, Figure 1 The loading mechanism can move along the loading X-axis guide rail 19, and the unloading mechanism can move along the unloading X-axis guide rail 18.

[0093] In this embodiment, the loading mechanism grabs the battery 17 and places it on a carrier 16 with eight receiving slots. The carrier 16, holding eight batteries 17, first passes through the cleaning assembly station. The cleaning lifting unit 33 drives the cleaning laser output unit 35 up and down. The cleaning laser output unit 35 includes a laser head, a galvanometer assembly, and other structures to ensure accurate laser output and cleaning. The cleaning transverse movement unit 34 drives the cleaning lifting unit 33 and the cleaning laser output unit 35 to move laterally together to adjust the position of the laser cleaning of the battery 17. The cleaning laser output unit 35 is located above the reference panel 32. The laser beam emitted by the cleaning laser output unit 35 passes through the reference channel 20 of the reference panel 32 to laser clean the position of the battery 17 to be cleaned. The reference lifting unit 31 drives the reference panel 32 up and down.

[0094] After cleaning, the battery 17 passes through the nailing assembly 4 for processing. The vibrating plate 41 is used to output the sealing nails. The nail suction X-axis movement unit 45, the nail suction Y-axis movement unit 46, and the nail suction Z-axis movement unit 47 can respectively drive the nail suction unit 44 to adjust its position in the horizontal, longitudinal, and vertical directions. The nail installation and photography movement unit 43 can drive the nail installation and photography unit 42 to move. The nail installation and photography unit 42 can accurately position the sealing nails and inspect their quality and nailing results. The nail installation and photography unit 42 can select a CCD camera component. After the sealing nails are absorbed, the nail suction unit 44 can be used to nail the sealing nails into the nail holes of the battery 17, completing the nailing process. The nail suction unit 44 is not limited to sucking nails, but also includes nailing, ejecting the absorbed sealing nails through gas.

[0095] The battery 17 after nailing is spot-welded by the pre-welding mechanism 5, as shown in FIG. Figure 5 As shown, the pre-welding unit is equipped with a pre-welding reference unit 302, which assists the pre-welding laser output unit 28 in positioning the battery 17. The pre-welding X-axis movement unit 29, the pre-welding Y-axis movement unit 30, and the pre-welding Z-axis movement unit 301 provide position adjustment for the pre-welding laser output unit 28 in the X-axis, Y-axis, and Z-axis directions. In this embodiment, the Z-axis direction is vertical, while the X-axis and Y-axis directions are horizontal, horizontal, and vertical directions. The pre-welding reference unit 302 is equipped with a pre-welding reference hole 25, through which the laser beam output by the welding laser output unit can pass to weld the battery 17. A waste recovery structure can be provided on one side of the pre-welding reference hole 25 in the pre-welding reference unit 302 to recover the generated polluted gases. The pre-welding laser output unit 28 and the laser welding output unit both include a laser head, a galvanometer assembly, and other structures. The pre-welding reference unit 302 is located above the carrier 16 and below the pre-welding laser output unit 28. In this embodiment, the pre-welding reference unit 302 is provided with a plurality of pre-welding reference holes 25 , which reduces the process of separately positioning a plurality of batteries 17 , and allows positioning and pre-welding of a plurality of batteries 17 at one time.

[0096] The nail suction trough 101 of the NG nail removal mechanism 10 recycles unqualified sealing nails through multiple nail suction pipes 102. The NG nails referred to are unqualified sealing nails. A nail suction port is provided at one end of the nail suction pipe to absorb NG nails, and detect unqualified sealing nails and recycle the sealing nails on the welded battery 17.

[0097] In this embodiment, the welding X-axis moving unit 305, the welding Y-axis moving unit 306, and the welding Z-axis moving unit 307 can provide position adjustment for the welding laser output unit 304 in the X-axis direction, the Y-axis direction, and the Z-axis direction. Each welding mechanism in this embodiment ensures two welding laser output units 304, two welding Z-axis moving units 307, and two welding Y-axis moving units 306. Each welding Z-axis moving unit 307 is set on the moving end of the Y-axis moving unit, and the two welding Y-axis moving units 306 are set on the two moving ends of the welding X-axis moving unit 305, that is, they share the guide rail of the welding X-axis moving unit 305, saving overall space and being able to weld two batteries 17 at the same time.

[0098] Finally, the inspection mechanism performs 2D and 3D inspections on the battery 17, providing a comprehensive and accurate understanding of the weld's two-dimensional and three-dimensional information. The weld's height, width, length, shape, volume, and other characteristics can all be precisely inspected. The unloading mechanism deposits unqualified batteries 17 into the unqualified product area 15, while qualified batteries 17 are deposited onto the unloading belt 14 for output.

[0099] In this embodiment, the carrier 16 can move on the X-axis conveyor line 23 and the Y-axis conveyor line 24. In this embodiment, the X-axis conveyor line 23 and the Y-axis conveyor line 24 can be selected as linear modules, and multiple carriers 16 are detachably connected to each other through connecting grooves A and connecting cams. In another embodiment, the X-axis conveyor line 23 can select a linear guide and a driving mechanism, and the carrier can slide on the linear guide. The driving mechanism includes a driving lateral moving mechanism C, a telescopic mechanism D and a driving cam E. The outer side of the X-axis conveyor line 23 is provided with a driving mechanism to prompt the carrier on the X-axis conveyor line to move along the conveying direction; when the driving mechanism drives one of the carriers 16 to move along the direction of the feeding return line, it drives all the connected carriers 16 to move. In order to improve the driving efficiency, two driving mechanisms are provided on the outer side of the X-axis conveyor line 23. The locking position set at the bottom of the carrier 16 can meet the driving mechanism's conditions for moving the carrier 16. After the driving lateral moving mechanism C drives the telescopic mechanism D and the driving cam E to move to the position corresponding to the locking position, the telescopic mechanism D drives the driving cam E to extend in the locking direction and clamp. At this time, the driving lateral moving mechanism C drives the telescopic mechanism D and the driving cam E to move along the feeding return line, thereby moving the carrier 16, that is, the front and back directions of the feeding return line. In this embodiment, the front direction of the feeding return line is the direction of the loading mechanism toward the welding mechanism, that is, the direction of the pre-welding mechanism toward the welding mechanism. The setting of the driving cam E can avoid collisions during the connection and positioning process and has the function of guiding the sliding into the positioning, thereby ensuring the stability and accuracy of the drive. Similarly, the carriers 16 are connected to the connecting cam B through the connecting groove A. The connecting cam B can slide out or slide into the connecting groove A horizontally in the direction perpendicular to the moving direction of the feeding return line, so as to realize convenient disassembly and linkage of the connected carriers 16, greatly improving maintenance efficiency and reducing investment costs. The Y-axis conveyor line 24 is a linear module, which can separate the connected carriers 16 and match them to the carrier 16 of another X-axis conveyor line 23, thereby forming a circular reflux, that is, completing the mutual transfer of the two X-axis conveyor lines 23, such as Figure 9 shown.

[0100] The carrier 16 is provided with at least eight accommodating slots to clamp at least eight batteries 17. In this embodiment, there are eight accommodating slots, which are position No. 1, position No. 2, position No. 3, position No. 4, position No. 5, position No. 6, position No. 7 and position No. 8. The first welding mechanism 6 can weld the battery 17 at position No. 1 and the battery 17 at position No. 2, the second welding mechanism 7 can weld the battery 17 at position No. 3 and the battery 17 at position No. 4, the third welding mechanism 8 can weld the battery 17 at position No. 5 and the battery 17 at position No. 6, and the fourth welding mechanism 9 can weld the battery 17 at position No. 7 and the battery 17 at position No. 8.
