The turntable driving mechanism 23 may be composed of a rotating motor and the like, and only needs to drive the turntable 21 to rotate, which may be specifically designed with reference to the existing disc loading device and will not be described in detail. Taking this as an example: the battery loading and unloading device 1, the seal nail loading device 3 and the ultrasonic welding device 4 are sequentially arranged around the turntable 21 along the circumferential direction of the turntable 21. Compared with a linear conveying device, the turntable device can save more space, so that the whole structure is more compact.

Further, an abutting piece 2243 which can abut against the battery 100 in a second horizontal direction perpendicular to the first horizontal direction is provided on a surface of the first holding piece 2241 which contacts the battery 100. Taking the first horizontal direction as the left-right direction as an example, the second horizontal direction is also the front-rear direction. The lower connecting member may be a block structure, and may be abutted against the battery 100 in the second horizontal direction, without limitation.

The jig frame 221 and/or the first clamping member 2241 are/is provided with a second clamping driver 225, and the second clamping driver 225 is connected with a second clamping member 226 for driving the second clamping member 226 to move close to or away from the abutting member 2243 in the second horizontal direction.

With this design, the welding head 423 is able to ultimately output rotational energy. The torque converter 424 may be designed with reference to an existing torque converter or may be directly used, which is not described in detail. For example, the bonding tool 423 may be designed as an indented bonding tool 423, the bottom of the bonding tool 423 of the indented bonding tool 423 specifically has a plurality of indented irregular planes, and the type and size of the indented bonding tool 423 and the like may be selected according to actual needs without limitation. For the case that no welding layer is arranged between the sealing nail and the liquid injection hole, the above-mentioned solution of the tooth welding head 423 with the torque converter 424 can be adopted, the amplitude transformer 422 transmits vibration energy to the torque converter 424, the vibration energy is converted into rotation energy by the torque converter 424 and then transmitted to the tooth welding head 423, and then the sealing nail rotates relative to the liquid injection hole, so that the contact surface between the sealing nail and the liquid injection hole is welded. This process may also be combined with the use of the drive assembly 43 such that the articulating horn 423 has not only a rotational energy output, but also an up and down vibratory energy output to achieve a better weld.

Further, in terms of the drive assembly 43 design, it includes a slide rail 432, a mount 433, and a horn driver 431.

The sliding rail 432 is mounted on the column 442; the mounting base 433 is slidably mounted on the slide rail 432; the amplitude transformer 422 is arranged on the mounting base 433; the horn driver 431 is connected to the mount 433 for movement by driving the mount 433. The design of slide rail 432 and mount 433 for the lift control of horn 422 is more steady. The welding head driver 431 may be an electric push rod or a pneumatic push rod, and is not particularly limited.

Further, a displacement sensor 434 is also included; displacement sensor 434 is mounted on column 442 for detecting the sliding displacement of mount 433. The displacement sensor 434 may be a grating scale, and is not limited specifically. The displacement sensor 434 is arranged to enable the welding head driver 431 to more accurately drive the welding assembly 42 to move up and down.

Further, the ultrasonic welding device 4 is further provided with a protective cover 45, which is mounted on the pillar 442 and covers the welding assembly 42 to protect the welding assembly 42.

Further, as shown in fig. 1 and 2, the present application is also designed with a cleaning device 5. The cleaning device 5 and the seal nail feeding device 3 are arranged in this order in the conveying direction of the conveying device 2. Specifically, the cleaning device 5 may be disposed around the turntable 21, and located between the battery loading and unloading device 1 and the seal nail loading device 3, and after the battery 100 is loaded, the excess electrolyte on the liquid injection hole of the battery 100 may be cleaned before the seal nail is loaded, so as to avoid the excess electrolyte at the liquid injection hole and the dust from affecting the welding effect between the seal nail and the liquid injection hole. The cleaning device 5 may be an existing laser cleaning mechanism in the market, and a person skilled in the art can select the cleaning device according to actual needs without limitation. Because one cleaning device 5 is added, the number of the battery positioning fixtures 22 is correspondingly increased on the original basis.

Further, as shown in fig. 10 and 11, the battery inspection device 6 and the defective product carrying device 7 for inspecting whether or not the battery 100 itself is acceptable are also included.

The battery detection device 6 is arranged around the turntable 21 and located between the ultrasonic welding device 4 and the battery loading and unloading device 1 and is used for detecting the welded battery 100, and because the welding mode of the ultrasonic welding device is ultrasonic welding, the welding gap problem does not need to be detected by additionally adding stations, so that the battery detection device 6 is designed to detect whether the battery 100 is qualified or not, namely, the battery 100 is integrally detected. The battery detection device 6 may be a commercially available CCD battery detection device 6, and is not limited in particular.

The battery loading and unloading device 1 is further configured to transport the battery 100 detected by the battery detection device 6 to the defective product conveying device 7, that is, when the battery detection device 6 detects that the welded battery 100 is not defective, and at this time, when the battery loading and unloading device 1 performs unloading on the unqualified battery 100, the battery is unloaded to the defective product conveying device 7 instead of the normal battery conveying device 8 shown in fig. 2, so that unloading is distinguished from the defective product. The defective product conveying device 7 may include a conveying mechanism 71 and a defective product collecting tank 72; this defective products collecting vat 72 can be used for collecting unqualified battery 100, and transport mechanism 71 then drives the motion of defective products collecting vat 72 to the defective products collecting vat 72 that will collect to fill transports to follow-up processing station department and handles. The transportation mechanism 71 may be a screw slide, a pneumatic slide, a conveyor belt, or the like, and is not limited in particular. Because one battery detection device 6 and one defective product conveying device 7 are added, the number of the battery positioning jigs 22 is correspondingly increased by two on the original basis. The battery conveying device 8 may be composed of two parallel conveying lines, and taking the battery loading and unloading device 1 as including the battery loading and unloading mechanism 101 as an example, one of the two conveying lines is also used for conveying the batteries 100 for loading, and the other is used for conveying the batteries 100 for welding and unloading. When the battery loading and unloading device 1 includes the battery loading mechanism 102 and the battery unloading mechanism 103, both the battery loading mechanism 102 and the battery unloading mechanism 103 can be configured with one battery conveying device 8, at this time, the conveying line of the battery conveying device 8 configured for the battery loading mechanism 102 is only used for conveying the batteries 100 for loading, and the conveying line of the battery conveying device 8 configured for the battery unloading mechanism 103 is only used for conveying the batteries 100 welded and unloaded.

While the sealing nail ultrasonic welding apparatus provided in the present application has been described in detail, those skilled in the art will appreciate that the present disclosure is not limited thereto, and that the present disclosure may be modified in various embodiments and applications.
