Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] like Figure 1 and Figure 4 As shown, the multi-channel transfer device 100 of some embodiments of this application includes a frame 110 and a conveying mechanism 120. The conveying mechanism 120 is disposed on the frame 110 and is used to carry and drive the battery cells to move. The conveying mechanism 120 includes a conveying drive 121, two drive shafts 122, two transmission components 123, and a conveying roller assembly 124. The conveying drive 121 is disposed on the frame 110. The two drive shafts 122 are spaced apart along their axial direction. The actuating end of the conveying drive 121 is connected to the adjacent ends of the two drive shafts 122. The two transmission components 123 are respectively disposed at both ends of the conveying roller assembly 124. Each drive shaft 122 is connected to one end of the conveying roller assembly 124 through the corresponding transmission component 123.

[0031] The axis of the drive shaft 122 is parallel to the first direction X. Two drive shafts 122 are spaced apart along the first direction X. The ends of the two drive shafts 122 that are close to each other along the first direction X are the first drive end 1221 and the second drive end 1222, respectively. The conveying drive component 121 is centrally located between the two drive shafts 122. The actuating end of the conveying drive component 121 is connected to both the first drive end 1221 and the second drive end 1222. The conveying drive component 121 is a common motor. The conveying roller assembly 124 includes multiple conveying rollers 1241. The axis of the conveying rollers 1241 is parallel to the first direction X. The conveying roller assembly 124 conveys battery cells along the second direction Y. The first direction X and the second direction Y are two parallel horizontal directions. The drive shafts 122 are rotatably mounted on the frame 110 via bearing brackets 127. The two drive shafts 122 can be coaxial or non-coaxial. The lengths of the two drive shafts 122 can be the same or different.

[0032] The multi-channel transfer device 100 of this application embodiment includes two drive shafts 122. The conveying drive 121 is connected to the close ends of the two drive shafts 122. The two drive shafts 122, together with the transmission assembly 123, drive the conveying roller 1241 of the conveying roller assembly 124 to rotate. This can balance the load balance of the drive shafts 122, reduce the risk of the drive shafts 122 breaking due to excessive load when conveying large-size lithium batteries, and improve the reliability and safety of sorting and transferring large-size lithium batteries.

[0033] like Figure 1 As shown, in some embodiments of this application, the conveying mechanism 120 further includes an intermediate shaft 125, the execution end of the conveying drive 121 is connected to the intermediate shaft 125 for transmission, the intermediate shaft 125 is arranged axially between two drive shafts 122, and the two ends of the intermediate shaft 125 are respectively connected to the drive shaft 122 on the same side for transmission.

[0034] The axis of the intermediate shaft 125 is parallel to the first direction X. The execution end of the conveying drive 121 is connected to the intermediate shaft 125 through a gear assembly. The two ends of the intermediate shaft 125 are connected to the first drive end 1221 and the second drive end 1222 respectively through a coupling 126.

[0035] With this configuration, the intermediate shaft 125 can drive the two drive shafts 122 to rotate synchronously. This not only simplifies the structure but also balances the load on the two drive shafts 122, reducing the risk of drive shaft 122 breakage.

[0036] In other embodiments, the actuator of the conveying drive 121 may be directly connected to the two drive shafts 122 via a gear assembly.

[0037] like Figure 4 As shown, in some embodiments of this application, the transmission assembly 123 includes a transmission belt 1231 and a plurality of spaced transmission wheels 1232, the transmission shaft 122 is connected to the transmission belt 1231, the conveying roller assembly 124 includes a plurality of spaced conveying rollers 1241, the outer side of the transmission belt 1231 is connected to the end of the conveying roller 1241, and the inner side of the transmission belt 1231 is connected to the transmission wheels 1232.

[0038] The drive shaft 122 has an output gear at its end, and a drive belt 1231 is mounted on the output gear and multiple drive pulleys 1232. The multiple drive pulleys 1232 are spaced apart along the second direction Y and are connected to the drive belt 1231 from the inside. Multiple conveying rollers 1241 are spaced apart along the first direction X, and the ends of the conveying rollers 1241 are equipped with synchronous pulleys, which are connected to the drive belt 1231 from the outside.

[0039] With this configuration, power can be transmitted from the drive shaft 122 to one end of the conveyor roller assembly 124. The two drive shafts 122 drive one end of the conveyor roller assembly 124 to rotate through the corresponding drive components 123. The transmission process is smooth and reliable, and the load is uniform.

[0040] In a preferred embodiment, a plurality of drive wheels 1232 are located below the synchronous wheels of a plurality of conveying rollers 1241, and each synchronous wheel is located between two adjacent drive wheels 1232 along the second direction Y.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in some embodiments of this application, the multi-channel transfer device 100 further includes a guide mechanism 130, which is disposed on the frame 110. The guide mechanism 130 is disposed on the upper side of the conveying mechanism 120. The guide mechanism 130 includes a plurality of guide components 131 arranged at intervals. The guide components 131 are used to guide the movement of battery cells.

[0042] Multiple guide components 131 are spaced apart along the first direction X. The guide components 131 are arranged on the upper side of the conveying roller assembly 124 along the vertical direction Z. The guide components 131 are used to guide the battery cells along the second direction Y. A conveying channel 132 is formed between two adjacent guide components 131. One conveying channel 132 is used to convey one battery cell.

[0043] like Figure 2 and Figure 3As shown, the guiding assembly 131 includes a guiding bracket 1311 and guiding wheels 1312. The guiding mechanism 130 also includes a mounting frame 133, which is fixed to the frame 110. The guiding bracket 1311 is fixed to the mounting frame 133 by a hanger. The length direction of the guiding bracket 1311 extends along the second direction Y. Four guiding wheels 1312 are provided, two of which are installed on the feeding side of the guiding bracket 1311 along the second direction Y, and the other two are installed on the discharging side of the guiding bracket 1311 along the second direction Y. By contacting the battery cells through rolling friction, the wear on the surface of the battery cells during their movement can be reduced.

[0044] This configuration allows battery cells to be guided into the conveying channel 132 along the second direction Y, thereby improving the positional accuracy of the battery cells and facilitating docking with devices such as the NG sorting line 220 on the discharge side.

[0045] In other embodiments, the guide assembly 131 may also extend from the gap in the conveyor roller assembly 1241.

[0046] like Figure 5 As shown, in some embodiments of this application, every two guide components 131 are arranged in pairs and constructed as a guide unit, and multiple guide units are spaced apart in the first direction X, and a conveying channel 132 is formed between the two guide components 131 of a guide unit.

[0047] For example, there are ten conveying channels 132 and twenty guiding components 131, with each pair of guiding components 131 forming a conveying channel 132.

[0048] This configuration increases the spacing between two adjacent conveying channels 132, improves the safety of conveying individual battery cells, and facilitates docking with upstream and downstream devices.

[0049] In other embodiments, two adjacent conveying channels 132 may also share the same guide assembly 131 to reduce the number of guide assemblies 131 arranged.

[0050] like Figure 3 and Figure 6 As shown, in some embodiments of this application, the conveyor roller assembly 124 includes a plurality of spaced conveyor rollers 1241, and the multi-channel transfer device 100 further includes a push rod mechanism 140. The push rod mechanism 140 includes a plurality of push rod assemblies 141, including push rods 1411 and push rod drive members 1412. The push rods 1411 can extend from the gap between two adjacent conveyor rollers 1241, and the push rod drive members 1412 are disposed on the frame 110 and are used to drive the push rods 1411 to rise and fall.

[0051] Multiple push rod assemblies 141 are spaced apart along the first direction X. The push rod drive 1412 is a cylinder. Driven by the push rod drive 1412, the push rod 1411 switches between a retracted position and a raised position. When the push rod 1411 is in the retracted position, the end of the push rod 1411 is below the conveying plane of the conveying roller assembly 1244 in the vertical direction Z. The battery cell abuts against the conveying roller 1241 and moves along the second direction Y under the rotation of the conveying roller 1241. When the push rod 1411 is in the raised position, the end of the push rod 1411 is higher than the conveying plane of the conveying roller assembly 1244, which can lift the battery cell and disengage it from the conveying roller 1241.

[0052] With this configuration, the battery cells can be lifted using the push rod assembly 141 when they are not being conveyed, thus preventing the bottom of the battery cells from coming into contact with the conveying roller 1241 and causing wear.

[0053] like Figure 3 and Figure 6 As shown, in some embodiments of this application, the push rod 1411 includes a connecting part (not shown) and a rod part 1414. The connecting part is located on the lower side of the conveying roller assembly 124. The actuating end of the push rod drive member 1412 is connected to the connecting part, and the rod part 1414 is connected to the connecting part. The rod part 1414 is disposed at the gap between two adjacent conveying rollers 1241.

[0054] In other words, a push rod drive 1412 drives multiple rods 1414 to move up and down synchronously via a connecting part. The connecting part is located on the lower side of the conveyor roller assembly 124 along the vertical direction Z, and the rods 1414 can extend out from the gap between two adjacent conveyor rollers 1241 along the vertical direction Z.

[0055] like Figure 6 As shown, an insulating layer 1415 is sleeved on the end of the rod 1414. The insulating layer 1415 is made of rubber or plastic, which can increase the friction when in contact with the battery cell and insulate the battery cell, thereby improving the safety performance of the device.

[0056] For example, there are two rods 1414, which are spaced apart along the second direction Y, and the two rods 1414 and a connecting part form a top rod 1411 with a U-shaped structure.

[0057] This design increases the contact area between the top rod 1411 and the battery cell, improving the stability of the battery cell during lifting and lowering.

[0058] In some embodiments of this application, multiple push rod assemblies 141 are spaced apart along the first direction X. Each push rod assembly 141 corresponds to a conveying channel 132. When battery cells have been fed into the conveying channel 132 and the entire multi-channel transfer device 100 is not full, the push rod assembly 141 can lift up the battery cells in the conveying channel 132 to prevent the bottom of the battery cells from rubbing against the conveying roller 1241.

[0059] In other embodiments, depending on the number of conveying channels 132 corresponding to one cycle, one push rod assembly 141 may correspond to multiple conveying channels 132 in the first direction X. For example, the multi-channel transfer device 100 has a total of ten conveying channels 132, with two conveying channels 132 receiving material in each cycle. One push rod assembly 141 corresponds to two conveying channels 132 simultaneously in the first direction X, and can simultaneously lift the battery cells in two conveying channels 132.

[0060] In some embodiments of this application, multiple push rod assemblies 141 can be arranged along the second direction Y within the same conveying channel 132. The push rod assemblies 141 within the same conveying channel 132 operate synchronously to jointly lift a single battery cell. In other embodiments, the same contact area can also be achieved by changing the number of rod portions 1414 of the push rod 1411 corresponding to each push rod drive member 1412.

[0061] like Figure 1 and Figure 6 As shown, in some embodiments of this application, the multi-channel transfer device 100 includes a barrier mechanism 150, including a discharge barrier 151 and a barrier drive 152. The discharge barrier 151 is disposed on the outlet side of the conveying mechanism 120, and the barrier drive 152 is disposed on the frame 110 for driving the discharge barrier 151 to rise and fall.

[0062] The discharge barrier 151 extends along the first direction X in its length direction. The barrier drive 152 is a cylinder used to drive the discharge barrier 151 to move along the vertical direction Z so that the discharge barrier 151 is located above the conveying plane of the conveying roller assembly 124 in the vertical direction X, or lowered below the conveying plane to avoid the discharge path of the battery cells.

[0063] This configuration prevents individual battery cells from falling off the conveyor roller assembly 124 along the second direction Y, thus improving the reliability of the multi-channel transfer device 100.

[0064] like Figure 3 As shown, in some embodiments of this application, the multi-channel shuttle device 100 includes a first sensing component 171 for detecting the movement of a single battery cell into place and sending a deceleration signal, and the transport drive 121 is configured to respond to the deceleration signal and decelerate.

[0065] Multiple first sensing components 171 are provided, each corresponding to a conveying channel 132. Each conveying channel 132 has a corresponding first sensing component 171 mounted on its guide bracket 1311 of the guide assembly 131. The first sensing component 171 can be a laser beam sensor. When a battery cell is conveyed along the second direction Y, and the first sensing component 171 detects its passage, it determines that the battery cell is about to move to a preset position. The conveying drive component 121 then responds by decelerating, reducing the conveying speed of the conveying roller assembly 124.

[0066] By setting the first sensing component 171, the conveying roller assembly 124 can be decelerated in a timely manner. For large-size lithium batteries, the characteristics of their large weight can be fully considered, and the degree of swaying under inertia can be reduced.

[0067] like Figure 3 As shown, in some embodiments of this application, the multi-channel transfer device 100 includes a second sensing component 172, which is used to detect the movement of a single battery cell into position and send an in-position signal. The transfer drive 121 is configured to respond to the in-position signal and stop.

[0068] Similar to the first sensing component 171, multiple second sensing components 172 are also provided. Each second sensing component 172 corresponds to one conveying channel 132. The first sensing component 171 and the second sensing component 172 of each conveying channel 132 are spaced apart along the second direction Y on the corresponding guide component 131. Along the conveying direction of the conveying roller assembly 124, the second sensing component 172 is located downstream of the first sensing component 171. When a battery cell is conveyed along the second direction Y, and the second sensing component 172 detects the passage of a battery cell, it determines that the battery cell has reached a preset position. The conveying drive component 121 responds and stops the conveying roller assembly 124, stopping the conveying, and the battery cell remains at the preset position.

[0069] By setting the second sensing component 172, the conveying roller assembly 124 can stop in time, improving the positional accuracy of the battery cells.

[0070] like Figure 5 As shown, in some embodiments of this application, the multi-channel transfer device 100 includes a third sensing component 173, which is used to detect the head of a battery cell entering the conveyor roller assembly 124 and send a start signal. The conveyor drive 121 is configured to respond to the start signal and start.

[0071] The conveyor roller assembly 124 conveys battery cells along the second direction Y. The head of the battery cell refers to the side of the battery cell that first enters the conveyor roller assembly 124 along the second direction Y. The first sensing assembly 171 is a through-beam sensor, with both the transmitting end and the receiving end disposed on the frame 110, and disposed at both ends of the plurality of conveying channels 132 along the first direction X. The third sensing assembly 173 is disposed on the feed side of the conveyor roller assembly 124 along the second direction Y.

[0072] By setting the third sensing component 173, the battery cell feeding can be detected in time. The conveying drive component 121 starts and drives the conveying roller 1241 of the conveying roller assembly 124 to rotate, so as to continue to convey the battery cell along the second direction Y.

[0073] like Figure 5 As shown, in some embodiments of this application, the multi-channel transfer device 100 includes a fourth sensing component 174, which is used to detect the battery cell leaving the conveyor roller assembly 124 and send a stop signal. The conveyor drive 121 is configured to respond to the stop signal and stop.

[0074] The fourth sensing component 174 is a through-beam sensor, with both the transmitting end and the receiving end set on the frame 110, and respectively set at both ends of the multiple conveying channels 132 along the first direction X; the fourth sensing component 174 is set on the discharge side of the conveying roller assembly 124 along the second direction Y.

[0075] By setting the fourth sensing component 174, it is possible to detect in a timely manner that the battery cell has completely left the conveying roller assembly 124. The conveying drive 121 stops after detecting that the battery cell has been unloaded, and will be restarted when the next cycle receives the battery cell.

[0076] like Figure 7 As shown, in some embodiments of this application, the multi-channel shuttle device 100 further includes a shuttle drive mechanism 160 for driving the frame 110 to move.

[0077] The ferry drive mechanism 160 is used to drive the frame 110 to move along the first direction X. The ferry drive mechanism 160 is a common linear drive mechanism. In other embodiments, the ferry drive mechanism 160 can also drive the frame 110 to move along other paths.

[0078] The frame 110 can move along the first direction X, which can enable the conveying mechanism 120 to connect with different feeding lines 210 and receive battery cells of corresponding grades from different feeding lines 210; it can also switch between receiving position and unloading position.

[0079] like Figure 8 As shown, some embodiments of the sorting equipment 200 of this application include a multi-channel transfer device 100.

[0080] In some embodiments of this application, the sorting equipment 200 includes a plurality of feeding lines 210, which are spaced apart along a first direction X, and the feeding lines 210 are connected to the loading side of the multi-channel transfer device 100.

[0081] For example, there are five feeding lines 210 and ten conveying channels 132. One feeding line 210 provides two battery cells per cycle, occupying two conveying channels 132.

[0082] In some embodiments of this application, the sorting equipment 200 further includes an NG sorting line 220, which is connected to the unloading side of the multi-channel transfer device 100.

[0083] The NG sorting line 220 includes multiple barcode scanning channels and rejection mechanisms. The barcode scanning channels correspond one-to-one with the conveying channels 132. After the battery cells in each conveying channel 132 enter the barcode scanning channel, they are scanned to check whether they are qualified products. Then, the rejection mechanism removes the NG materials, and the qualified battery cells are unloaded and stored together.

[0084] Due to the characteristics of the multi-channel transfer device 100 in this application embodiment, the sorting equipment 200 in this application embodiment can also improve the reliability and safety of sorting and transferring large-size lithium batteries.

[0085] like Figures 1 to 8 As shown, the working principle of the multi-channel shuttle device 100 in this embodiment is as follows:

[0086] The shuttle drive mechanism 160 drives the frame 110 to move to the discharge point of a feeding line 210 to receive two battery cells of the same grade.

[0087] When the conveying drive unit 121 is started, power is transmitted to the end of the conveying roller assembly 124 through two drive shafts 122 and the same-side transmission assembly 123, driving the conveying roller 1241 to rotate from both ends, and the battery cell enters the corresponding conveying channel 132 along the second direction Y.

[0088] The first sensing component 171 detects that the battery cell has moved into place, and the conveying drive 121 slows down. The second sensing component 172 detects that the battery cell has moved into place, and the conveying drive 121 stops running, thus completing the receiving action of one cycle of the battery cell.

[0089] The shuttle drive mechanism 160 drives the frame 110 to move to the discharge point of another feeding line 210 to receive two more battery cells of the same grade.

[0090] When the conveying drive 121 is started, the battery cell of this cycle enters the corresponding conveying channel 132 along the second direction Y. The push rod mechanism 140 of the conveying channel 132 corresponding to the battery cell of the previous cycle pushes the battery cell in the conveying channel 132 upward so that its bottom does not contact the conveying roller assembly 124.

[0091] With the feedback cooperation of the first sensing component 171, the second sensing component 172 and the conveying drive component 121, the receiving action of the battery cell in this cycle is completed.

[0092] Driven by the transfer drive mechanism 160, the frame 110 moves sequentially to the discharge point of other feeding lines 210 until all conveying channels 132 receive battery cells, becoming a full-load multi-channel transfer device 100.

[0093] Driven by the shuttle drive mechanism 160, the frame 110 moves to the unloading position, all the top rod mechanisms 140 descend, all the battery cells are placed on the surface of the conveyor roller assembly 124, the barrier mechanism 150 descends, and the conveyor roller assembly 124 drives all the battery cells to be discharged along the second direction Y and enter the NG sorting line 220 for NG sorting.

[0094] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0095] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
