Fig. 2 shows an alternative embodiment of the battery sheet feeding device according to the present invention.
In order to solve the technical problem that the battery piece feeding device in the prior art can not realize automatic detection of the battery piece in the feeding process. The invention provides a battery piece feeding device, and the battery piece feeding device provided by the invention is described in an embodiment by combining with fig. 2 to 4.
The battery piece feeding device provided by the invention at least comprises one feeding sub-device, and the feeding sub-device can independently finish the feeding of the battery piece. As shown in fig. 2, in some embodiments, the battery sheet feeding device of the present invention includes only one feeding sub-device. As shown in fig. 3, in other embodiments, the battery piece feeding device of the present invention includes two feeding sub-devices arranged side by side, where the two feeding sub-devices can implement parallel feeding, so as to improve the feeding efficiency of the battery piece.
With continued reference to fig. 2 and 3, the loading sub-device includes a loading mechanism 20, a conveying mechanism 30, a detecting mechanism (not shown), and a placing mechanism 40.
The loading mechanism 20 is located at the loading end of the conveying mechanism 30, and the loading mechanism 20 is configured to place the battery piece toward the conveying mechanism 30. The conveying mechanism 30 conveys the battery pieces from the charging end to the discharging end.
The detection mechanism is located at a side of the conveying mechanism 30, and the detection mechanism is configured to detect the battery piece on the conveying mechanism 30.
The placement mechanism 40 is located at the discharge end of the conveying mechanism 30, and the placement mechanism 40 is configured to remove and place the battery piece on the discharge end of the conveying mechanism 30 to a predetermined position. For example, in some embodiments, placement mechanism 40 places the inspected battery cells on the outfeed end onto a subsequent welding conveyor line, and places the inspected battery cells on the outfeed end at a recovery station.
Therefore, through the cooperation of the feeding mechanism 20, the conveying mechanism 30, the detecting mechanism and the placing mechanism 40, the battery piece feeding device can realize automatic feeding of battery pieces and can realize detection of the battery pieces in the feeding process.
Optionally, the battery piece feeding device of the invention further comprises a recovery storage mechanism, and the placement mechanism 40 removes and places the battery pieces which are unqualified after detection on the discharge end of the conveying mechanism 30 to the recovery storage mechanism.
Optionally, the battery piece feeding device of the invention further comprises a battery storage mechanism 10 for storing the battery pieces to be fed. The battery storage mechanism 10 may be a battery storage rack provided fixedly, a battery box driven by a conveyor belt, or the like.
As shown in fig. 3, when the battery piece feeding device includes two feeding sub-devices, a battery storage mechanism 10 may be disposed at a side of each of the two feeding sub-devices, and the feeding mechanisms 20 of the two feeding sub-devices pick up the battery pieces from the corresponding battery storage mechanisms 10, respectively.
In some embodiments, the battery pieces to be charged are all of the same type, for example, the battery pieces to be charged are all right-angle battery pieces, at this time, the battery storage mechanism 10 is configured to store right-angle battery pieces, and the feeding mechanism 20 is configured to move between the battery storage mechanism 10 and the feeding end of the conveying mechanism 30, so as to pick up and place the right-angle battery pieces in the battery storage mechanism 10 on the conveying mechanism 30. For example, the battery pieces to be fed are chamfered battery pieces, at this time, the battery storage mechanism 10 is configured to store the chamfered battery pieces, and the feeding mechanism 20 is configured to move between the battery storage mechanism 10 and the feeding end of the conveying mechanism 30, so as to pick up and place the chamfered battery pieces in the battery storage mechanism 10 on the conveying mechanism 30.
It should be noted that: in practical implementations, the loading mechanism 20 may be configured to pick up one battery piece at a time and place the picked up battery piece on the conveying mechanism 30, e.g., only one pick-up portion is provided on the loading mechanism 20. The feeding mechanism 20 may also be configured to pick up two battery pieces at a time and place the two picked up battery pieces side by side on the conveying mechanism 30, for example, two pick-up portions are provided on the feeding mechanism 20.
In other embodiments, the battery pieces to be fed include two different types, such as a right angle battery piece and a chamfer battery piece, and in these embodiments, in order to implement sorting storage and feeding of the two types of battery pieces, as shown in fig. 2 and 3, the battery storage mechanism 10 includes a first battery storage mechanism 11 for storing the right angle battery pieces and a second battery storage mechanism 12 for storing the chamfer battery pieces, and the conveying mechanism 30 includes two parallel-arranged first conveying mechanisms 31 for conveying the right angle battery pieces and second conveying mechanisms 32 for conveying the chamfer battery pieces. The loading mechanism 20 is configured to pick up the rectangular battery pieces from the first battery storage mechanism 11 and place them on the first conveying mechanism 31, and pick up the chamfered battery pieces from the second battery storage mechanism 12 and place them on the second conveying mechanism 32.
In these embodiments, the loading mechanism 20 may be configured to be provided with only one pickup portion that picks up and places one rectangular battery piece in the first battery storage mechanism 11 on the first conveying mechanism 31 at a time, or picks up and places one chamfered battery piece in the second battery storage mechanism 12 on the second conveying mechanism 32 at a time.
The loading mechanism 20 may also be configured to be provided with two pick-up portions capable of simultaneously picking up one rectangular battery piece in the first battery storage mechanism 11 and one chamfered battery piece in the second battery storage mechanism 12 at a time and placing them on the first conveying mechanism 31 and the second conveying mechanism 32, respectively. Of course, the feeding mechanism 20 with such a structure may pick up only one right-angle battery piece or one chamfer piece at a time and place the same on the corresponding conveying mechanism, that is, the two pick-up portions may be capable of independently performing the pick-up action.
As shown in fig. 4, in some embodiments, the loading mechanism 20 includes a spindle drive mechanism (not shown), a spindle 21, a first carrying portion 22, and a second carrying portion 23, wherein: the first carrying part 22 and the second carrying part 23 are connected to the rotating shaft 21 and located at both sides of the rotating shaft 21, and the first carrying part 22 and the second carrying part 23 are respectively provided with a pickup part for picking up the battery piece. The power output end of the rotating shaft driving mechanism is connected with the rotating shaft 21, the rotating shaft driving mechanism drives the rotating shaft 21 to rotate so as to drive the first carrying part 22 and the second carrying part 23 to synchronously rotate to realize position exchange, and when the first carrying part 22 rotates above the battery storage mechanism 10, the second carrying part 23 rotates above the feeding end of the conveying mechanism 30.
So set up, can realize the rotatory material loading to the battery piece to promote material loading efficiency. For example, as shown in fig. 4, when the pickup portion on the second carrying portion 23 carries a battery piece to the loading end of the battery piece loading conveyor 30 and drops the battery piece to be welded, the first carrying portion 23 reaches just above the battery storage mechanism 10 to pick up another battery piece to be welded, and vice versa.
In the loading mechanism 20 of the embodiment of fig. 4, only one pickup portion is provided on each carrying portion, so that the carrying portion can pick up only one battery piece at a time. The pick-up part is arranged on the carrying part in a sliding way, and the pick-up part realizes the position adjustment of the pick-up part in the horizontal direction through sliding. With this arrangement, it is possible to realize the pickup of the battery pieces stored at the different battery storage mechanisms by the pickup portion, such as the first battery storage mechanism 11 and the second battery storage mechanism 12 in the foregoing embodiment, and also possible to realize the pickup of the battery pieces picked up by the pickup portion on the different conveying mechanisms, such as the first conveying mechanism 31 and the second conveying mechanism 32 in the foregoing embodiment.
Of course, in other embodiments, two picking units may be disposed on the first carrying unit 22 and the second carrying unit 23, respectively, and each carrying unit may pick up two battery pieces at a time. In these embodiments, when the battery pieces to be fed are all right angle battery pieces or chamfer battery pieces, each handling portion can pick up two right angle battery pieces or two battery pieces at a time. When the battery piece to be fed comprises the right-angle battery piece and the chamfer battery piece, each carrying part can pick up one right-angle battery piece and one chamfer battery piece at a time.
Alternatively, the first conveying mechanism 31 and the second conveying mechanism 32 are stepping mechanisms, the driving portion of the first conveying mechanism 31 and the driving portion of the second conveying mechanism 32 are electrically connected with a control module, and the control module independently controls the driving portion of the first conveying mechanism 31 and the driving portion of the second conveying mechanism 32 to drive respectively.
The conveying mechanism is set to be a stepping mechanism, so that the stepping type transmission of the battery piece can be realized, namely: each time the driving part of the conveying mechanism drives, the conveying mechanism carries the battery piece to move forwards for a preset distance and stay for a preset time period until the driving part drives for the next time. When the conveying mechanism is in the stay period, the charging mechanism 20 places the battery piece to the charging end of the conveying mechanism, and the placing mechanism 40 picks up the battery piece from the discharging end of the conveying mechanism, so that the charging mechanism 20 is convenient for discharging and taking materials of the conveying mechanism.
The battery piece feeding device provided by the embodiment of the invention can be applied to a battery piece series welding device to feed the battery pieces to be welded onto a welding conveying belt of the series welding device. In some embodiments, the placement mechanism 40 of the battery piece feeding device is configured to move between the first conveying mechanism 31 and the welding conveyor belt to place the right angle battery pieces conveyed on the first conveying mechanism 31 on the welding conveyor belt, and the placement mechanism 40 is further configured to move between the second conveying mechanism 32 and the welding conveyor belt to place the chamfer battery pieces conveyed on the second conveying mechanism 32 on the welding conveyor belt.
Since the battery strings are formed by sequentially welding a predetermined number of battery pieces, the battery piece feeding device is required to sequentially convey and stack the predetermined number of battery pieces onto the welding conveying line. As described above, when the battery piece feeding device in the embodiment of the invention is used to perform battery piece feeding, the unqualified battery pieces on the conveying mechanism 30 are removed from the conveying mechanism 30 by the placement mechanism 40 and placed at the recovery storage mechanism. When unqualified battery pieces are removed and recovered, the battery pieces are liable to be in shortage. Therefore, in order to ensure that the battery piece feeding device can convey and stack a predetermined number of battery pieces on the welding conveying line, it is necessary to perform timely material supplementing to compensate for the shortage of battery pieces caused by the fact that unqualified battery pieces are removed and recovered.
Based on the above consideration, in the process of feeding the battery pieces, each time the placement mechanism 40 removes a defective battery piece from the discharging end of the conveying mechanism 30, the feeding mechanism 20 immediately picks up a battery piece of the same type as the removed defective battery piece from the battery storage mechanism 10 and places the battery piece at the feeding end of the conveying mechanism 30, thereby realizing timely feeding of the battery piece.
Specifically, in some embodiments, the feeding process of the battery piece feeding device in the invention is as follows: the loading mechanism 20 picks up and places the battery piece at the loading end of the conveying mechanism 30, and the conveying mechanism 30 conveys the loaded battery piece towards the discharging end. During the conveying process, the detection mechanism detects the battery piece on the conveying mechanism 30. The placement mechanism 40 removes the qualified battery pieces from the discharge end of the conveying mechanism 30, places the qualified battery pieces on the welding conveyor belt according to a preset stacking mode, and recovers the unqualified battery pieces from the discharge end of the conveying mechanism 30. In particular, each time the placement mechanism 40 retrieves a defective battery piece from the discharge end of the conveying mechanism 30, the loading mechanism 20 then places a battery piece of the same type as the retrieved defective battery piece on the loading end of the conveying mechanism 30.
In some series welded embodiments, the battery pieces to be welded include right angle battery pieces and chamfer battery pieces, and in order to achieve sorting feeding of the two types of battery pieces, the conveying mechanism 30 includes a first conveying mechanism 31 and a second conveying mechanism 32 disposed side by side, respectively. In these embodiments, the feeding mechanism 20 places one rectangular battery piece and one chamfering battery piece on the feeding end of the first conveying mechanism 31 and the feeding end of the second conveying mechanism 32 of the conveying mechanism 30, respectively, until the discharging of the predetermined number of rectangular battery pieces and the predetermined number of chamfering battery pieces is completed. The placement mechanism 40 removes the battery pieces from the discharge ends of the first conveying mechanism 31 and the second conveying mechanism 32, respectively, and stacks the battery pieces onto the welding conveyor.
As different types of battery cells cannot be welded into the same battery string. To prevent mixing, the placement mechanism 40 optionally first continuously conveys a predetermined number of right angle battery pieces from the first conveyor mechanism 31 and stacks the right angle battery pieces in turn onto a welding conveyor belt to be welded to form a string of right angle battery strings.
