In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0055] like Figures 1 to 5 As shown, an embodiment of the utility model provides a battery conveying device and a welding machine, the welding machine includes a welding device 2 and the above-mentioned battery conveying device 1, wherein the welding device 2 includes a welding assembly 21 and a metal sheet conveying assembly 22, the battery conveying assembly 11 is used to convey the battery 100 to the welding station, the metal sheet conveying assembly 22 is used to convey the discharge metal sheet 200 to the welding station, and contact the discharge metal sheet 200 with the pole 101 of the battery 100 at the welding station; the welding assembly 21 is used to weld the discharge metal sheet 200 to the battery 100 at the welding station.

[0056] The battery 100 is transported to the welding station through the battery conveying device 1, and the discharge metal sheet 200 is transported to the welding station through the metal sheet conveying assembly 22, and the discharge metal sheet 200 is made to contact with the pole 101 of the battery 100 at the welding station. Then, the battery 100 at the welding station and the discharge metal sheet 200 in contact with the pole 101 of the battery 100 are welded through the welding assembly 21, so that the discharge metal sheet 200 and the pole 101 of the battery 100 can be quickly welded without manual operation, thereby improving the recycling efficiency of the battery 100.

[0057] The battery conveying device 1 includes a battery conveying component 11, and the battery conveying component 11 includes a battery conveying line 111 and a spacing adjustment unit 112. The battery conveying line 111 includes a battery conveyor belt 1111 for conveying batteries 100; the spacing adjustment unit 112 includes two battery limit baffles 1121 and a spacing adjustment drive module, the two battery limit baffles 1121 are spaced apart along the width direction of the battery conveyor belt 1111, and the spacing adjustment drive module is used to drive the battery limit baffles 1121 to move along the width direction of the battery conveyor belt 1111; at least two battery conveying components 11 are provided, and at least two battery conveying components 11 are distributed along the conveying direction of the battery 100; among two adjacent battery conveying components 11, the battery conveyor belt 1111 of the downstream battery conveying component 11 can receive the battery 100 conveyed by the battery conveyor belt 1111 of the upstream battery conveying component 11.

[0058] For two adjacent battery conveying assemblies 11, after a model of battery 100 is loaded, once all the batteries 100 of this model are conveyed to the battery conveyor belt 1111 of the downstream battery conveying assembly 11, the distance between the two battery limit baffles 1121 in the upstream battery conveying assembly 11 can be adjusted according to the size of the next model of battery 100, and then the battery 100 of this model is loaded onto the battery conveyor belt 1111 of the upstream battery conveying assembly 11; after the battery 100 of the previous model is separated from the battery conveyor belt 1111 of the downstream battery conveying assembly 11, the distance between the two battery limit baffles 1121 in the downstream battery conveying assembly 11 is adjusted; and then the battery 100 conveyed by the upstream battery conveying assembly 11 begins to be conveyed into the battery conveyor belt 1111 of the downstream battery conveying assembly 11. It can be achieved that when the model of the battery 100 is changed, the entire battery conveying device 1 does not need to stop conveying the battery 100, which improves the efficiency of the battery conveying device 1 in conveying the battery 100.

[0059] In some embodiments, the battery conveyor line 111 also includes a battery conveyor rack 1113, and each of the two battery limit baffles 1121 in the battery conveyor assembly 11 is respectively equipped with a spacing adjustment drive module. In this way, according to the model of the battery 100 to be conveyed, the two battery limit baffles 1121 of the same battery conveyor assembly 11 can be able to move synchronously under the action of the corresponding spacing adjustment drive module, so that the two battery limit baffles 1121 are close to or away from each other along the width direction of the battery conveyor belt 1111, so as to realize the use of the two battery limit baffles 1121 to limit the battery 100 along the width direction of the battery conveyor belt 1111, thereby preventing the battery 100 conveyed by the battery conveyor belt 1111 from tipping over.

[0060] It should be noted that, one of the two battery limit baffles 1121 of the same battery conveying assembly 11 can be fixed to the battery conveying frame 1113, and the other can be equipped with a spacing adjustment drive module. The spacing adjustment drive module can drive the battery limit baffle 1121 connected thereto to move along the width direction of the battery conveyor belt 1111, thereby realizing the spacing adjustment of the two battery limit baffles 1121 along the width direction of the battery conveyor belt 1111.

[0061] In some embodiments, Figure 2 and Figure 3 As shown, the spacing adjustment drive module includes a spacing adjustment nut 1125, a spacing adjustment screw 1122, a spacing adjustment motor 1123, a spacing adjustment fixing and a spacing adjustment guide rod 1124, wherein the spacing adjustment nut 1125 is fixedly connected to the battery conveyor rack 1113, the spacing adjustment screw 1122 is threadedly connected to the spacing adjustment nut 1125, and one end of the spacing adjustment screw 1122 is rotatably connected to the battery limit baffle 1121; the output end of the spacing adjustment motor 1123 is connected to the other end of the spacing adjustment screw 1122, and is used to drive the spacing adjustment screw 1122 to rotate, the spacing adjustment fixing is fixed to the battery conveyor rack 1113, one end of the spacing adjustment guide rod 1124 is fixed to the corresponding battery limit baffle 1121, and the other end is slidably connected to the spacing adjustment fixing along the width direction of the battery conveyor belt 1111.

[0062] When it is necessary to adjust the spacing between the two battery limit baffles 1121 along the width direction of the battery conveyor belt 1111, the spacing adjustment motor 1123 is controlled to drive the spacing adjustment screw 1122 to rotate relative to the battery limit baffle 1121. Since the spacing adjustment nut 1125 threadedly connected to the spacing adjustment screw 1122 is fixed to the battery conveyor rack 1113, the spacing adjustment nut 1125 can neither rotate nor move axially. Moreover, since the spacing adjustment guide rod 1124 and the spacing adjustment fixing member connected to the battery limit baffle 1121 are slidingly connected along the width direction of the battery conveyor belt 1111, and the spacing adjustment fixing member is fixed to the battery conveyor rack 1113, the battery limit baffle 1121 is restricted from rotating, and the spacing adjustment screw 1122 will drive the battery limit baffle 1121 and the spacing adjustment motor 1123 connected thereto to move axially along the spacing adjustment screw 1122, thereby realizing the spacing adjustment of the two battery limit baffles 1121 along the width direction of the battery conveyor belt 1111.

[0063] Exemplarily, the spacing adjustment screw 1122 is rotatably connected to the battery limit baffle 1121 via a rotating bearing to improve the smoothness of the spacing adjustment screw 1122 when rotating relative to the battery limit baffle 1121.

[0064] It should be noted that the structure of the spacing adjustment drive module is not limited to the above-mentioned motor nut screw structure, but can also be other types of motor nut screw structures in the prior art, such as the spacing adjustment motor 1123 drives the spacing adjustment screw 1122 to rotate, and limits the spacing adjustment nut 1125 to rotate, so that the spacing adjustment nut 1125 drives the battery limit baffle 1121 to move. The spacing adjustment drive module can also be a cylinder, a linear motor, an electric push rod, a motor gear rack mechanism, etc., which is not specifically limited here.

[0065] In some embodiments, Figure 2 and Figure 3 As shown, the spacing adjustment fixing member includes a bearing seat 1126 and a sliding bearing, wherein the bearing seat 1126 is fixed to the battery conveying frame 1113; the spacing adjustment guide rod 1124 is slidably connected to the bearing seat 1126 along the axial direction of the spacing adjustment lead screw 1122 through the sliding bearing. Such a configuration can not only limit the rotation of the battery limit baffle 1121, but also guide the movement of the battery limit baffle 1121.

[0066] Exemplarily, each spacing adjustment drive module includes two spacing adjustment guide rods 1124 and two spacing adjustment fixings, the two spacing adjustment guide rods 1124 and the two spacing adjustment fixings correspond one to one, the two spacing adjustment guide rods 1124 are arranged at intervals along the conveying direction of the battery 100, and the spacing adjustment screw 1122 is located between the two spacing adjustment guide rods 1124 along the conveying direction of the battery 100, so that the battery limit baffle 1121 has better stability during the movement process.

[0067] In some embodiments, Figure 2 and Figure 3 As shown, the battery conveyor line 111 also includes two battery conveyor pulleys and a battery conveyor motor 1112, wherein the two battery conveyor pulleys are rotatably mounted on the two ends of the battery conveyor frame 1113 along the conveying direction of the battery 100, the battery conveyor belt 1111 is wound around the outside of the two battery conveyor pulleys, and the output end of the battery conveyor motor 1112 is connected to one of the battery conveyor pulleys.

[0068] By controlling the battery conveying motor 1112 to work, the battery conveying motor 1112 drives the battery conveying pulley connected thereto to rotate, and with the cooperation of another battery conveying pulley, the battery conveyor belt 1111 outputs the battery 100 along the conveying direction of the battery 100.

[0069] In some embodiments, Figure 2 and Figure 3 As shown, the conveying direction of the battery 100 is the length direction of the battery 100. With such a configuration, when the battery 100 is conveyed by the battery conveyor belt 1111, the probability of the battery 100 falling due to inertia at the moment when the battery conveyor belt 1111 starts and stops can be reduced.

[0070] In some embodiments, Figure 2 and Figure 3 As shown, the welding device 2 also includes an anti-dumping assembly 23, which includes an anti-dumping baffle 231. The anti-dumping baffle 231 is located downstream of the welding station and can abut against the battery 100 conveyed to the welding station along the conveying direction of the battery 100.

[0071] When the battery conveyor belt 1111 stops and the battery 100 stays at the welding station, the battery 100 on the battery conveyor belt 1111 may tilt forward due to inertia at the moment the battery conveyor belt 1111 stops. At this time, the battery 100 will abut against the anti-dumping baffle 231 transported to the welding station along the conveying direction of the battery 100, and the anti-dumping baffle 231 is used to limit the battery 100, thereby effectively preventing the battery 100 from tipping over due to inertia at the moment the battery conveyor belt 1111 stops.

[0072] In addition, when welding the pole 101 of the battery 100 and the discharge metal sheet 200, the anti-dumping baffle 231 and two battery limit baffles 1121 are used to limit the battery 100 on three sides. In actual application, it is found that the positioning accuracy of the battery 100 can be improved from ±5mm to ±0.2mm, ensuring that the discharge metal sheet 200 can be accurately welded to the pole 101 of the battery 100, greatly improving the welding pass rate of the pole 101 of the battery 100 and the discharge metal sheet 200.

[0073] In some embodiments, Figures 3 to 5 As shown, the anti-dumping assembly 23 also includes an anti-dumping driving unit 232, the output end of the anti-dumping driving unit 232 is connected to the anti-dumping baffle 231, and the anti-dumping driving unit 232 is used to drive the anti-dumping baffle 231 to move so that the anti-dumping baffle 231 can switch between the anti-dumping position and the idle position; when the anti-dumping baffle 231 is in the anti-dumping position, the anti-dumping baffle 231 can abut against the battery 100 conveyed to the welding station along the conveying direction of the battery 100; when the anti-dumping baffle 231 is in the idle position, the battery 100 at the welding station can move along the conveying direction of the battery 100 to the downstream of the welding station.

[0074] Before the battery 100 to be welded is moved to the welding station, the anti-dumping baffle 231 is driven to the anti-dumping position by the anti-dumping driving unit 232 to limit the battery 100; after welding is completed, the anti-dumping baffle 231 is driven to the idle position by the anti-dumping driving unit 232, and the battery 100 is transported to the downstream of the welding station by the battery conveyor belt 1111 for the next step.

[0075] Exemplarily, the idle position is located below the anti-dump position, the anti-dump drive unit 232 is located below the anti-dump baffle 231, and the anti-dump drive unit 232 is used to drive the anti-dump baffle 231 to rise and fall so that the anti-dump baffle 231 can switch between the anti-dump position and the idle position.

[0076] It should be noted that the anti-dumping drive unit 232 can be a drive structure capable of realizing linear movement in the prior art, such as a linear motor, a cylinder, or an electric push rod. In some other embodiments, the anti-dumping drive unit 232 can also drive the anti-dumping baffle 231 to move linearly along the width direction of the battery conveyor belt 1111, so that the anti-dumping baffle 231 switches between the anti-dumping position and the idle position. The anti-dumping drive unit 232 can also drive the anti-dumping baffle 231 to rotate, so that the anti-dumping baffle 231 switches between the anti-dumping position and the idle position.

[0077] In some embodiments, Figure 1 ,like Figures 3 to 5As shown, in order to improve welding efficiency, two welding stations are provided, and the discharge metal sheets 200 are welded to the two poles 101 of the battery 100 respectively at the two welding stations.

[0078] Specifically, the welding machine includes two welding devices 2, and the battery conveying device 1 includes two battery conveying components 11, which are respectively a first battery conveying component and a second battery conveying component arranged in sequence along the conveying direction of the battery 100; the anti-dumping component 23 of one of the welding devices 2 is located between the first battery conveying component and the second battery conveying component, and the anti-dumping component 23 of the other welding device 2 is located downstream of the second battery conveying component.

[0079] The upstream welding station is marked as the first welding station, and the downstream welding station is marked as the second welding station. When the battery 100 is at the first welding station, the battery 100 is supported by the battery conveyor belt 1111 of the first battery conveying assembly; when the battery 100 is at the second welding station, the battery 100 is supported by the battery conveyor belt 1111 of the second battery conveying assembly.

[0080] After the battery 100 at the first welding station completes the welding of one pole 101 and the discharge metal sheet 200, the battery 100 is transported to the second welding station, where the welding of another pole 101 and the discharge metal sheet 200 of the battery 100 is completed, and then the welded battery 100 is transferred to other stations.

[0081] In some embodiments, the welding assembly 21 includes a welding head 211 and a welding pressing driving member 212, the output end of the welding pressing driving member 212 is connected to the welding head 211, and the welding pressing driving member 212 is used to drive the welding head 211 to descend, so as to weld the pole 101 of the battery 100 at the welding station and the discharge metal sheet 200. Exemplarily, the discharge metal sheet 200 is an aluminum foil, the welding head 211 is an ultrasonic welding head, and the welding pressing driving member 212 is a cylinder. The welding pressing driving member 212 drives the welding head 211 to descend, and the welding head 211 presses through the adhesive tape on the discharge metal sheet 200 and the pole 101. The ultrasonic welding head 211 works to produce a local high temperature at the contact surface of the discharge metal sheet 200 and the pole 101 to be welded together, so as to prepare for the subsequent discharge of the battery 100.
