As a result, the casting and welding machine needs to complete all the processing procedures for a batch of storage batteries and output the storage batteries before it can receive the next batch of storage batteries for processing, resulting in relatively low overall efficiency. Content of the Utility Model

Detailed implementation manners

[0026] The following will further elaborate on the present utility model in conjunction with the accompanying drawings and specific implementation manners.

[0027] As Figure 1As shown in the figure, this embodiment provides an automatic battery welding machine, which includes a welding machine body 1, a feeding platform 2 arranged at the inlet and outlet ends of the welding machine body 1, a feeding platform 3 and a discharging platform 4 respectively arranged on the left and right sides of the feeding platform 2. A soldering flux dipping mechanism and a liquid suction mechanism are arranged on the feeding platform 3, and a secondary battery group slotting mechanism is arranged on the discharging platform 4. A battery transfer mechanism is arranged above the feeding platform 3, the feeding platform 2 and the discharging platform 4. The overall working principle of this automatic welding machine is as follows: Use transfer equipment such as a manipulator to invert the first batch of batteries (specifically 8 in this embodiment) on the feeding platform 3, that is, place them in a state where the lugs are downward. Then, the soldering flux dipping mechanism completes the soldering flux dipping process for the lugs, and then the liquid suction mechanism sucks off the excess soldering flux on the lugs, leaving only a layer of soldering flux on the surface of the lugs. Subsequently, the battery transfer mechanism transfers the first batch of batteries to the feeding platform 2, and the feeding platform 2 sends the first batch of batteries into the welding machine body 1 for welding. While this process is underway, the feeding platform 3 can receive the second batch of batteries, that is, while the first batch of batteries is being welded, the second batch of batteries is undergoing the soldering flux dipping and liquid suction processes. When the first batch of batteries is completed and welded and sent out of the welding machine body 1, the first batch of batteries is transferred to the discharging platform 4 through the battery transfer mechanism, and the secondary battery group slotting mechanism on the discharging platform 4 presses the battery group into the shell (when welding, the lugs need to be exposed as much as possible, so the battery group is not fully slotted). While this process is underway, the second batch of batteries is transferred from the feeding platform 3 to the feeding platform 2, and the feeding platform 3 receives the third batch of batteries. In this way, the soldering flux dipping process for the third batch of batteries, the welding process for the second batch of batteries, and the secondary slotting process for the first batch of batteries can be carried out synchronously, thereby improving the overall battery processing efficiency. Finally, the batteries that have completed the secondary slotting can be transferred away from the discharging platform 4 by transfer equipment such as a manipulator.

[0028] As Figure 2 shown, a first slide rail 31 and a first linear driving device 32 are arranged on the feeding platform 3. A first turnover plate 33 is slidably connected to the first slide rail 31, and the output end of the first linear driving device 32 is connected to the first turnover plate 33. A soldering flux dipping mechanism and a liquid suction mechanism are arranged below the first turnover plate 33 in sequence along its moving direction. Among them, the first linear driving device 32 can adopt a rodless cylinder, which is arranged on the side of the first turnover plate 33 to drive the first turnover plate 33 to move along the first slide rail 31, so as to realize the movement of the first turnover plate 33 between the soldering flux dipping mechanism and the liquid suction mechanism. A hole for the battery lugs to extend downward is opened on the first turnover plate 33 to facilitate the inversion of the battery. The second and third turnover plates have the same structure. According to the sequence of the process, the liquid suction mechanism is closer to the feeding platform 2 than the soldering flux dipping mechanism, so as to transfer the battery to the feeding platform 2 faster after completing the lug liquid suction process.

[0029] The structures of the casting and soldering liquid dipping mechanism and the liquid suction mechanism are simple and convenient to use. Among them, the casting and soldering liquid dipping mechanism includes a dipping liquid box 341 and a first lifting drive device 342 provided at the bottom of the dipping liquid box 341. A plurality of tab dipping holes are provided on the upper side of the dipping liquid box 341. The first lifting drive device 342 can be a cylinder. The dipping liquid box 341 contains casting and soldering liquid. When a storage battery is inverted on the first turnover plate 33, the first lifting drive device 342 jacks up the dipping liquid box 341 so that the tabs are inserted into the tab dipping holes to dip the soldering aid liquid, and then the dipping liquid box 341 descends and the tabs extend out of the tab dipping holes. The liquid suction mechanism includes a liquid suction box 351, a second lifting drive device 352 provided at the bottom of the liquid suction box 351, and an air extraction device communicating with the liquid suction box 351. A plurality of tab liquid suction holes are provided on the upper side of the liquid suction box 351. The structural principle of the liquid suction mechanism is quite similar to that of the soldering aid liquid dipping mechanism. The difference is that the liquid suction box 351 does not need to contain soldering aid liquid and is connected with an air extraction device to form a negative pressure in the liquid suction box 351, so as to suck the excess soldering aid liquid on the tabs into the liquid suction box.

[0030] As Figure 3 shown, a second slide rail 21 and a second linear drive device 22 are provided on the feeding platform 2. A second turnover plate 23 is slidably connected to the second slide rail 21. The output end of the second linear drive device 22 is connected to the second turnover plate 23. The second linear drive device 22 can be a rodless cylinder to drive the second turnover plate 23 to move along the second slide rail 21 to send the storage battery into the casting and soldering machine body 1 or send out the storage battery that has completed casting and soldering from the casting and soldering machine body 1. A cooling fan 24 is provided below the second turnover plate 23 and outside the casting and soldering machine body to cool the storage battery busbar formed by casting and soldering outside the casting and soldering machine body, improving the cooling efficiency.

[0031] As Figure 4 shown, a third slide rail 41 and a third linear drive device 42 are provided on the discharging platform 4. A third turnover plate 43 is slidably connected to the third slide rail 41. The output end of the third linear drive device 42 is connected to the third turnover plate 43. A receiving position and a secondary slotting position are arranged on the discharging platform 4 in sequence along the moving direction of the third turnover plate 43. Among them, the third linear drive device 42 can be a rodless cylinder to drive the third turnover plate 43 to move along the third slide rail 41. Since the secondary slotting of the storage battery needs to simultaneously press against its upper and lower ends, two working positions need to be set to avoid the structure pressing against the upper part of the storage battery affecting the reception of the storage battery. The receiving position is on the side close to the feeding platform 2 to facilitate the quick reception of the storage battery, and the secondary slotting position is closer to the outside of the equipment to facilitate the transfer of the storage battery that has completed secondary slotting by a transfer device such as a manipulator.

[0032] The second slotting mechanism for the electrode group includes a fourth slide rail 51 parallel to the third slide rail 41, a moving frame 52 slidably connected to the fourth slide rail 51, a fourth linear driving device 53 with its output end connected to the moving frame 52, a third lifting driving device 54 provided on the moving frame 52, a lower pressing plate 55 provided at the output end of the third lifting driving device 54, a fourth lifting driving device 56 provided below the discharge platform at the second slotting position, a jacking plate 57 provided at the output end of the fourth lifting driving device 56, and an electrode group top plate 58 provided on the jacking plate 57. Among them, the fourth linear driving device 53 can adopt a rodless cylinder, the third and fourth lifting driving devices can adopt cylinders, the moving frame 52 is specifically in the form of a gantry, the jacking plate 57 is a horizontal plate, the electrode group top plate 58 is a vertical plate, and the electrode group top plate 58 can avoid the electrode tabs and busbars and directly abut against the electrode group. Thus, the working principle of this mechanism is as follows: In the initial state, the moving frame 52 is at the second slotting position, and the third turnover plate 43 is at the receiving position. At this time, there is no obstruction at the receiving position, and the third turnover plate 43 can smoothly receive the battery. Subsequently, the third turnover plate 43 carrying the battery is moved to the second slotting position, then the lower pressing plate 55 is lowered to abut against the battery case, and at the same time, the jacking plate 57 and the electrode group top plate 58 are raised to abut against the electrode group and push the electrode group upward into the case; then the lower pressing plate 55 and the jacking plate 57 are reset, and the moving frame 52 moves towards the receiving position to expose the battery, facilitating the transfer of the battery by external transfer devices such as manipulators.

[0033] As Figure 5 and 6 shown, the battery transfer mechanism includes a gantry 61, a horizontal moving mechanism provided on the gantry 61, a lifting mechanism provided at the output end of the horizontal moving mechanism, and a battery gripper 62 provided at the output end of the lifting mechanism. Since the liquid suction mechanism on the feeding platform 3, the feeding platform 2, and the receiving position on the discharge platform 4 are in the same straight line, a simple and efficient gantry-type transfer mechanism can be used to achieve the efficient transfer of the battery. Among them, both the horizontal moving mechanism and the lifting mechanism can be realized by the cooperation of gears and racks, and the movement is more stable and reliable. The battery gripper 62 includes a gripper frame 621, a partition 622 provided in the middle of the gripper frame 621, and a plurality of pushing devices 623 provided on the opposite sides of the gripper frame 621. The output ends of the pushing devices 623 face the partition 622. The pushing devices 623 generally can adopt cylinders to cooperate with the partition 622 to clamp the battery. 4 batteries can be clamped on each side of the partition. Correspondingly, 4 pushing devices are arranged on each side respectively to ensure the stability of the clamping force.

[0034] Finally, it should be noted that the casting welding machine body 1 generally can adopt the existing casting welding method using a casting welding mold, which will not be elaborated here.

[0035] The above is only a preferred specific embodiment of the present utility model. This specific embodiment is a realization method based on the overall concept of the present utility model, and the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
