[0004] The existing battery string unloading device can only absorb one battery string. When the battery string unloading device fails to transfer the absorbed battery string to the downstream station in time, the unloading station will be occupied by the next battery string for a long time, thus interrupting the processing rhythm of the upstream loading station and the string connection station, and finally affecting the battery string production efficiency. Summary of the invention

[0005] In view of the above problems existing in the traditional battery string unloading device, the present application provides a battery string unloading device, and its detailed technical solution is as follows:

[0049] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] like Figures 1 to 6 As shown, the battery string transport device in the embodiment of the present application includes a frame 1, a lower picking mechanism 2 and an upper picking mechanism 3, wherein:

[0051] The lower picking mechanism 2 includes a first driving part 21, a first mounting beam 22, a first suction cup group 23 and a second suction cup group 24, wherein the first driving part 21 is arranged on the frame, the end of the first mounting beam 22 is connected to the movable part of the first driving part 21, and the first suction cup group 23 and the second suction cup group 24 are arranged on opposite sides of the first mounting beam 22.

[0052] The first driving unit 21 is used to drive the first mounting beam 22 to rise and fall, so as to drive one of the first suction cup group 23 and the second suction cup group 24 to suck the battery string located below the lower picking mechanism 2. The first driving unit 21 is also used to drive the first mounting beam 22 to rotate, so as to drive one of the first suction cup group 23 and the second suction cup group 24 to flip the sucked battery string to face upward.

[0053] The upper picking mechanism 3 includes a second driving part 31, a second mounting beam 32 and a third suction cup group 33, wherein the second driving part 31 is arranged on the frame 1, the end of the second mounting beam 32 is connected to the movable part of the second driving part 31 and is located above the first mounting beam 32, and the third suction cup group 33 is placed on the second mounting beam 32.

[0054] The second driving part 31 is used to drive the second mounting beam 32 to move up and down, so as to drive the third suction cup group 33 to suck the battery string from the upward one of the first suction cup group 23 and the second suction cup group 24. The second driving part 31 is also used to drive the second mounting beam 32 to move horizontally, so as to drive the third suction cup group 33 to carry the sucked battery string to the next station.

[0055] The battery string unloading device provided in the embodiment of the present application has a lower picking mechanism 2 provided with a first suction cup group 23 and a second suction cup group 24 capable of alternately picking up battery strings from a battery string conveyor line 10 .

[0056] In this way, when the upper picking mechanism 3 fails to promptly remove a battery string sucked by the lower picking mechanism 2 from the battery string conveyor line 10, the lower picking mechanism 2 can continue to pick up another battery string from the battery string conveyor line 10, thereby preventing the discharge station of the battery string conveyor line 10 from being occupied, causing the processing rhythm of the previous processing station to be interrupted.

[0057] like Figure 2 , Figure 4As shown, optionally, the first driving part 21 includes a lifting driving member 211, a mounting plate 212 and a first rotating driving member 213, wherein: the mounting plate 212 is liftably connected to the frame 1, and is connected to the driving end of the lifting driving member 211 disposed on the frame 1. The end of the first mounting beam 22 is rotatably connected to the mounting plate 212, and is connected to the driving end of the first rotating driving member disposed on the mounting plate 212. The lifting driving member 211 is used to drive the mounting plate 212 to lift and lower, so as to drive the first mounting beam 22 to lift and lower synchronously. The first rotating driving member is used to rotate the first mounting beam 22.

[0058] Through the cooperative driving of the lifting drive member 211 and the first rotating drive member, the first driving part 21 can drive the first mounting beam 22 to lift and lower, and can drive the first mounting beam 22 to rotate, thereby driving the first suction cup group 23 and the second suction cup group 24 to alternately absorb the battery string located under the lower picking mechanism 2, and flip the absorbed battery string to face upward.

[0059] Optionally, the frame 1 is provided with a first slide rail 214 extending in the vertical direction, and the mounting plate 212 is slidably connected to the first slide rail 214 via a slider. The lifting drive 211 drives the mounting plate 212 to slide up and down along the first slide rail 214 to prevent the mounting plate 212 from deviating.

[0060] like Figure 2 As shown, in order to further improve the smoothness of the lifting and rotation of the first mounting beam 22, the lower picking mechanism 2 includes two groups of symmetrically arranged first driving parts 21, and the two ends of the first mounting beam 22 are respectively connected to a mounting plate 212 of a group of first driving parts 21, and the two groups of first driving parts 21 synchronously drive the first mounting beam 22 to lift and rotate.

[0061] like Figure 3 As shown, the first suction cup group 23 and the second suction cup group 24 each include a plurality of (e.g. Figure 3 12) first suction cup assemblies, several first suction cup assemblies are arranged on the first mounting beam 22 at intervals along the length direction of the first mounting beam 22, wherein each first suction cup assembly includes two first suction cups 231 arranged perpendicular to the length direction of the first mounting beam 22.

[0062] By configuring the first suction cup group 23 and the second suction cup group 24 to include a plurality of first suction cup assemblies spaced apart along the length direction of the first mounting crossbeam 22, the first suction cup group 23 and the second suction cup group 24 can absorb the entire battery string extending along the length direction of the first mounting crossbeam 22, thereby preventing some battery cells in the battery string from falling, tearing the welding ribbon or causing damage to the battery cells. By configuring the first suction cup assembly to include two first suction cups 231, the absorption stability of the first suction cup assembly on the battery string can be ensured.

[0063] Optionally, the number of first suction cup assemblies in the first suction cup group 23 and the second suction cup group 24 is equal to and corresponds to the number of battery cells in the battery string. When the first suction cup group 23 and the second suction cup group 24 suck the battery string, each first suction cup assembly correspondingly sucks one battery cell. Since the first suction cup assembly includes two first suction cups 231, the first suction cup assembly can suck the battery cell from two locations in the width direction of the battery cell, thereby ensuring the suction stability of the battery cell.

[0064] Furthermore, if the lower pick-up mechanism 2 has only the first suction cup group 23, the first driving unit 21 will need to change the orientation of the first suction cup group 23 at a high frequency each time a battery string is picked up and transferred to the upper pick-up mechanism 3. If the first mounting beam 22 has both the first suction cup group 23 and the second suction cup group 24, the first driving unit 21 no longer needs to change the orientation of the suction cups of the first mounting beam 22 at a high frequency, and one flipping action can be omitted, that is, the beat is saved.

[0065] like Figure 5 and Figure 6 As shown, optionally, the second driving part 31 includes a translation driving module 311, a first frame 312, a lifting driving module 313 and a second frame 314, wherein: the first frame 314 is translationally connected to the frame 1, and is in driving connection with the translation driving module 311 disposed on the frame 1. The second frame 314 is liftably connected to the first frame 312, and is in driving connection with the lifting driving module 313 disposed on the first frame 312. The end of the second mounting beam 32 is connected to the second frame 314. The translation driving module 311 is used to drive the first frame 312 to translate relative to the frame 1, so as to drive the second mounting beam 32 to translate synchronously. The lifting driving module 313 is used to drive the second frame 314 to rise and fall relative to the first frame 312, so as to drive the second mounting beam 32 to rise and fall synchronously.

[0066] The working process of the upper picking mechanism 3 is as follows:

[0067] When the lower picking mechanism 2 turns the sucked battery string upward.

[0068] The translation drive module 311 drives the second mounting beam 32 to translate toward the battery string, so that the third suction cup group 33 moves to just above the battery string.

[0069] Next, the lifting drive module 313 drives the second frame 314 to slide downward relative to the first frame 312 until the third suction cup group 33 contacts and absorbs the battery string. Subsequently, the lifting drive module 313 drives the second frame 314 to slide upward relative to the first frame 312 to return to its original position.

[0070] Next, the translation drive module 311 drives the first frame 312 to translate relative to the rack 1 , so that the third suction cup group 33 moves the sucked battery string to the next station or other stations for inspection and NG.

[0071] Optionally, the frame 1 is provided with a second slide rail 315 extending in the horizontal direction, and the first frame 312 is slidably connected to the second slide rail 315 via a slider. The translation drive module 311 includes a driving motor 3111, a driving wheel 3112, a driven wheel 3113 and a synchronous belt 3114, wherein: the driving motor 3111 and the driven wheel 3113 are installed on the frame 1, the driving wheel 3112 is connected to the driving end of the driving motor 3111, the synchronous belt 3113 is sleeved on the driving wheel 3112 and the driven wheel 3113, and the first frame 312 is fixedly connected to one side of the synchronous belt 3114 (such as the lower side belt). The driving motor 3111 drives the synchronous belt 3114 to rotate via the driving wheel 3112 to drive the first frame 312 to slide along the second slide rail 315.

[0072] Optionally, a third slide rail 316 extending in the vertical direction is provided on the first frame 312, and the second frame 314 is slidably connected to the third slide rail 316 via a slider. The third slide rail 316 implements sliding guidance for the second frame 314 to prevent the second frame 314 from deviating during the lifting process.

[0073] Optionally, third slide rails 316 are provided at opposite ends of the first frame 312 , the two side frames of the second frame 314 are respectively slidably connected to a third slide rail 316 , and the top frame of the second frame 314 is connected to the synchronous belt 3114 .

[0074] The third suction cup group 33 may need to implement quality inspection of the battery string during the process of moving the battery string to the back-end workstation. In order to enable the battery string to face the detection mechanism, the second drive unit 31 optionally also includes a second rotating drive member disposed on the second frame 314, and the end of the second mounting beam 32 is rotatably connected to the second frame 314 and is transmission-connected to the driving end of the second rotating drive member. The second rotating drive member is used to drive the second mounting beam 32 to rotate, so as to drive the third suction cup group 33 to flip, thereby implementing the orientation adjustment of the battery string adsorbed on the third suction cup group 33, so as to facilitate the detection mechanism to implement the detection of the battery string.

[0075] Optionally, the upper picking mechanism 3 further includes a fourth suction cup group disposed on the second mounting crossbeam 32 and opposite to the third suction cup group 33. When the third suction cup group 33 is turned downward under the drive of the second mounting crossbeam 22, the fourth suction cup group is turned upward. Similarly, when the third suction cup group 33 is turned upward under the drive of the second mounting crossbeam 32, the fourth suction cup group is turned downward.

[0076] In this way, the third suction cup group 33 and the fourth suction cup group can alternately suck the battery string from the lower picking mechanism 2. That is, when the upper picking mechanism 3 cannot place the battery string sucked from the lower picking mechanism 2 to the downstream station in time, the upper picking mechanism 3 can continue to pick up and cache another battery string from the lower picking mechanism 2, thereby preventing the lower picking mechanism 2 from being occupied by the battery string, causing the processing rhythm of the upstream processing station to be interrupted.

[0077] Optionally, the third suction cup group 33 and the fourth suction cup group each include a plurality of second suction cup assemblies, which are arranged on the second mounting beam 32 at intervals along the length direction of the second mounting beam 32, wherein each second suction cup assembly includes two second suction cups arranged perpendicular to the length direction of the second mounting beam 32.

[0078] By configuring the third suction cup group 33 and the fourth suction cup group to include a plurality of second suction cup assemblies spaced apart along the length direction of the second mounting cross beam 32, the third suction cup group 33 and the fourth suction cup group can absorb the entire battery string, preventing some battery cells in the battery string from falling, tearing the welding ribbon or damaging the battery cells. By configuring the second suction cup assembly to include two second suction cups, the absorption stability of the second suction cup assembly on the battery string can be ensured.

[0079] The present application is described in sufficient detail above with certain particularity. It should be understood by those skilled in the art that the description in the embodiments is merely exemplary, and all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application. The scope of protection claimed in the present application is defined by the claims, rather than by the above description in the embodiments.
