[0039] In the related art, the compatibility and replacement efficiency of the battery cell transfer tray are low. When switching from one type of battery cell to another type of battery cell, the tray needs to be replaced, resulting in slow production progress, and the same tray cannot simultaneously compatible with multiple battery cell sizes and multiple battery cell postures, resulting in low production and replacement efficiency.

[0040] Based on the above considerations, in order to solve the technical problem that the existing battery cell transfer tray cannot simultaneously accommodate battery cells of multiple different sizes, the present application provides a tray device, which comprises a bottom plate, a first adjusting assembly and a second adjusting assembly. The first adjusting assembly is arranged on the bottom plate and comprises a first transmission assembly, an adjusting plate in transmission connection with the first transmission assembly, a support plate above the adjusting plate, at least one follower plate slidingly arranged on the adjusting plate in a first direction, and a first limiting piece arranged on the support plate and each follower plate. The first adjusting assembly is configured to move the adjusting plate along a second direction by the first transmission assembly, so that the adjusting plate drives all the follower plates to move along the first direction in a manner that the distance between adjacent two first limiting pieces is equal, so as to adjust the distance between the adjacent two first limiting pieces and limit the to-be-placed object between the adjacent two first limiting pieces. The second adjusting assembly is arranged on the bottom plate and comprises a second transmission assembly, a fixed plate in transmission connection with the second transmission assembly, and a second limiting piece arranged on the fixed plate. The fixed plate and the second limiting piece are arranged on at least one side of the first limiting piece in the second direction. The second adjusting assembly is configured to move the fixed plate along the second direction by the second transmission assembly, so as to adjust the distance between the first limiting piece and the second limiting piece and limit the to-be-placed object on one side of the second limiting piece in the second direction.

[0041] In the technical scheme of the present application, the first adjusting assembly is configured to move the adjusting plate along the second direction by the first transmission assembly, so that the adjusting plate drives all the follower plates to move along the first direction in a manner that the distance between adjacent two first limiting pieces is equal, so as to adjust the distance between the adjacent two first limiting pieces and limit the to-be-placed object between the adjacent two first limiting pieces. The second adjusting assembly is configured to move the fixed plate along the second direction by the second transmission assembly, so as to adjust the distance between the first limiting piece and the second limiting piece and limit the to-be-placed object on one side of the second limiting piece in the second direction. Thus, the distance between the adjacent two first limiting pieces and the distance between the first limiting piece and the second limiting piece can be adjusted simultaneously based on the different sizes of the to-be-placed object, such as the battery cell, so as to adapt to battery cells of multiple sizes, solve the problem that the existing battery cell transfer tray cannot simultaneously accommodate battery cells of multiple different sizes, and improve the production and retooling efficiency.

[0042] The technical scheme of the present application will be described in detail below with reference to the accompanying drawings.

[0043] Please refer to Figure 1 and Figure 2 , the present application provides a tray device, which comprises a bottom plate 1, a first adjusting assembly 2 and a second adjusting assembly 3.

[0044] The first adjusting assembly 2 is arranged on the bottom plate 1, and the first adjusting assembly 2 comprises a first transmission assembly 20, an adjusting plate 21 in transmission connection with the first transmission assembly 20, a support plate 28 located above the adjusting plate 21, at least one follower plate 22 arranged on the adjusting plate 21 and sliding in the first direction X, and a first limiting piece 23 arranged on the support plate 28 and each follower plate 22, and a space between adjacent two first limiting pieces 23 is used for accommodating the to-be-placed object. The first adjusting assembly 2 is configured to drive the adjusting plate 21 to move along the second direction Y by the first transmission assembly 20, so that the adjusting plate 21 drives all the follower plates 22 to move along the first direction X in a manner that the spacing between adjacent two first limiting pieces 23 is equal, so as to adjust the spacing between adjacent two first limiting pieces 23 to limit the to-be-placed object between the adjacent two first limiting pieces 23.

[0045] The second adjusting assembly 3 is arranged on the bottom plate 1, and the second adjusting assembly 3 comprises a second transmission assembly 30, a fixed plate 31 in transmission connection with the second transmission assembly 30, and a second limiting piece 32 arranged on the fixed plate 31. The fixed plate 31 and the second limiting piece 32 are arranged on at least one side of the first limiting piece 23 along the second direction Y. The second adjusting assembly 3 is configured to drive the fixed plate 31 to move along the second direction Y by the second transmission assembly 30, so as to adjust the spacing between the first limiting piece 23 and the second limiting piece 32, and limit the second limiting piece 32 on one side of the to-be-placed object along the second direction Y.

[0046] The bottom plate 1 can be a flat plate structure for supporting the first adjusting assembly 2 and the second adjusting assembly 3. The to-be-placed object can be a battery cell. When the pole of the battery cell is upward, the first direction X can be the thickness direction of the to-be-placed object such as the battery cell, and the second direction Y can be the length direction of the to-be-placed object such as the battery cell. The support plate 28 is a plate body arranged at the intermediate position of all the follower plates 22 for supporting the first limiting piece 23. The first limiting piece 23 can be a structure for limiting in the thickness direction of the battery cell, and the second limiting piece 32 can be a structure for limiting in the length direction of the plurality of battery cells. The first transmission assembly 20 can drive the adjusting plate 21 to move along the second direction Y, that is, the length direction of the battery cell, so that the adjusting plate 21 can drive all the follower plates 22 to move along the first direction X, that is, the thickness direction of the battery cell, in a manner that the spacing between adjacent two first limiting pieces 23 is equal. That is, when the adjusting plate 21 moves along the second direction Y, all the follower plates 22 move at the same time and are adjusted to have equal spacing between adjacent two first limiting pieces 23. Adjacent two first limiting pieces 23 form a limiting gap of the battery cell. The second transmission assembly 30 can drive the fixed plate 31 to move along the second direction Y, that is, the length direction of the battery cell, so as to adjust the spacing between the first limiting piece 23 and the second limiting piece 32.

[0047] In the technical scheme of the embodiment of the present application, the first adjusting assembly 2 is used to drive the first transmission assembly 20 to drive the adjusting plate 21 to move along the second direction, so that the adjusting plate 21 drives all the follower plates 22 to move along the first direction X in a manner that the spacing between the two adjacent first limiting members 23 is equal, so as to adjust the spacing between the two adjacent first limiting members 23 to limit the object to be placed between the two adjacent first limiting members 23; and the second adjusting assembly 2 is used to drive the second transmission assembly 30 to drive the fixed plate 31 to move along the second direction, so as to adjust the spacing between the first limiting member 23 and the second limiting member 32, and limit the second limiting member 32 on one side of the object to be placed along the second direction. Then, the spacing between the two adjacent first limiting members 23 and the spacing between the first limiting member 23 and the second limiting member 32 can be adjusted based on the different sizes of the object to be placed, such as the size of the battery cell, so as to adapt to battery cells of various sizes, and the problem that the battery cell transfer tray in the prior art cannot simultaneously accommodate battery cells of various sizes is solved, and the production and transformation efficiency is improved.

[0048] In some embodiments, the first limiting member 23 and the second limiting member 32 can be flexible members to avoid damaging the battery cell.

[0049] In some embodiments, please refer to Figure 1 and Figure 4 The two sides of the first limiting member 23 are respectively provided with a first limiting step 231, and the first limiting step 231 includes a first supporting surface 2311 and a first limiting surface 2312 which are perpendicular to each other.

The second limiting member 32 is provided with a second limiting step 321 which has the same height as the first limiting step 231, and the second limiting step 321 includes a second supporting surface 3211 and a third limiting surface 3212 which are perpendicular to each other. The two first supporting surfaces 2311, the two first limiting surfaces 2312 of the two adjacent first limiting members 23, the second supporting surface 3211 and the third limiting surface 3212 of the second limiting member 32, and the second limiting surface 233 form a limiting gap of the battery cell. The bottom of the battery cell is supported on the first supporting surface 2311 and the second supporting surface 3211, the thickness of the battery cell is limited between the first limiting surfaces 2312, and the length of the battery cell is limited between the second limiting surface 233 and the third limiting surface 3212.

[0050] Please refer to Figure 1 and Figure 4In other embodiments, the first limiting member 23 can further be provided with a third limiting step 232 on both sides, the third limiting step 232 being higher than the first limiting step 231 in the third direction Z, and the spacing of the third limiting step 232 in the first direction X between adjacent two first limiting members 23 being greater than the spacing of the first limiting step 231 in the first direction X. The second limiting member 32 is provided with a fourth limiting step 322, the third limiting step 232 and the fourth limiting step 322 having the same height, and the second limiting surface 233 can serve as the limiting of the first limiting step 231 and the third limiting step 232 on one side of the second direction Y. In this way, different limiting gaps can be selected based on the thickness of the battery cell, improving the applicability.

The support plate 28 is clamped on the second sliding rail 26 by the clamping block 29, and the support plate 28 is located in the middle of all follow-up plates 22, so that when the follow-up plates 22 on both sides of the support plate 28 move away from the support plate 28, the support plate 28 can remain stationary. The length and width of the support plate 28 can be consistent with the length and width of the follow-up plate 22.

[0053] In the technical scheme of the embodiment of the present application, the movement of the adjusting plate 21 along the second direction Y, i.e., the length direction of the battery cell, on the first sliding rail 24 is converted into the movement of all the follower plates 22 along the first direction X, i.e., the thickness direction of the battery cell, on the second sliding rail 26 in a manner that the spacing between the follower plate 22 and the support plate 28 and the spacing between adjacent two follower plates 22 are equal. Then, by adjusting the movement of the adjusting plate 21 along the second direction Y, the spacing between all the follower plates 22 or between the follower plate 22 and the support plate 28 adjacent to the follower plate 22 can be adjusted at the same time, and the spacing between all the adjacent first limit members 23 is ensured to be equal, without the need of adjusting one by one.

The diameter of the follower wheel 22 can be consistent with the groove width of the adjusting groove 211, so that the two side walls of the adjusting groove 211 can guide the follower wheel 22, so that the follower wheel 22 can slide along the length direction of the adjusting groove 211.

In some embodiments, the thread directions of the second transmission screw 302 on both sides of the length direction are opposite, so that when the second transmission screw 302 rotates, the second transmission nut 301 on both sides drives the fixing plate 31 and the second limiting piece 32 to move towards or away from each other, i.e., mirror image movement, so as to adjust the distance between the second limiting piece 32 and the first limiting piece 23 adjacent to it on both sides at the same time.

[0067] In the technical scheme of the embodiment of the present application, the second transmission screw 302 and the second transmission nut 301 are threadedly connected, and then when the second transmission screw 302 is driven to rotate, the movement of the fixing plate 31 and the second limiting piece 32 along the second direction Y can be adjusted.

[0069] Please refer to Figure 1 , Figure 6 and Figure 7 The tray device further includes a driving assembly 5, which is drivingly connected with the first transmission assembly 20 and the second transmission assembly 30. The first transmission screw 202 of the first transmission assembly 20 and the second transmission screw 302 of the second transmission assembly 30 are driven to rotate by the driving assembly 5.

[0070] Please refer to Figure 6 and Figure 7In some embodiments, the driving assembly 5 comprises a support 51, a first driving mechanism 52, a distance measuring mechanism 57, a third sliding rail 55 and a second driving mechanism 54, wherein the support 51 is arranged near one side of the bottom plate 1 along the second direction Y.

[0071] The first driving mechanism 52 can be a servo motor. The driving end of the first driving mechanism 52 is provided with the sleeve joint 53, which can be a sleeve. After the sleeve joint 53 is inserted into the end of the first transmission screw 202 or the second transmission screw 302, the position of the adjusting plate 21 or the fixed plate 31 can be accurately adjusted. The distance measuring mechanism 57 can be a laser distance measuring sensor, which is used to detect the positions of the first limiting part 23 and the second limiting part 32. The second driving mechanism 54 can be a pneumatic cylinder. When the second driving mechanism 54 acts, the second connecting plate 56 can be driven to move forward and backward, and then the second connecting plate 58 and the fourth sliding block 59 can be driven to slide on the third sliding rail 55 along the second direction Y, so that the sleeve joint 53 is inserted into or separated from the end of the first transmission screw 202 or the second transmission screw 302.

[0072] In the technical scheme of the embodiments of the present application, the first transmission screw 202 of the first transmission assembly 20 and the second transmission screw 302 of the second transmission assembly 30 can be driven to rotate by the driving assembly 5. The distance between the two adjacent first limiting parts 23 and the distance between the first limiting part 23 and the second limiting part 32 can be automatically and accurately adjusted based on the thickness and length of the battery cell.

[0075] (1) Initial state, the bottom plate 1 of the tray device is positioned on the conveying line, the drive assembly 5 and the head of the first transmission screw 202 are connected, and the current positions of the first limiting member 23 and the second limiting member 32 are detected by the distance measuring mechanism 57; taking the size of the square shell battery as an example, the thickness is 20 mm, the height is 100 mm, and the length is 300 mm.

[0076] (2) According to the model of the battery currently produced, the system sends the size parameters of the battery to the control system, and the control system controls the first drive mechanism 52 servo motor to drive the adjusting plate 21 to move, so that the limiting gap in the first direction X is adjusted to an appropriate gap, if the thickness of the battery is 20 mm, the limiting gap can be adjusted to about 26 mm, and a single side of 3 mm gap is provided for the machine clamp to place the battery; the drive assembly 5 is moved to the second transmission screw 302, and the limiting gap in the second direction Y is adjusted to an appropriate range, for example, if the length of the battery is 300 mm, the gap is adjusted to about 306 mm, and a single side of 3 mm gap is provided for the machine clamp to place the battery.

[0077] (3) The battery is placed on the tray by the machine clamp, at this time, the limiting gap of the battery is large, the drive assembly 5 adjusts the limiting gap of the battery in the first direction X and the second direction Y to an appropriate range, for example, for a 20 mm thick battery, the limiting gap is adjusted to 20 mm, so that the battery is compact in the warehouse and does not shake;

[0078] (4) After the battery is placed, the conveying line drives the battery and the tray device to the subsequent work station;

[0079] (5) Because of the current CTP battery pack process, the battery needs to be glued on the large surface, so the posture of the battery needs to be adjusted (adjusted from the pole upward to the large surface upward, to facilitate the large surface gluing). As in steps (2) and (3), the limiting gap is adjusted to 106 mm*306 mm, and the battery can still be normally placed in the limiting gap position after being rotated by 90 degrees.

[0080] The tray device of the present application is suitable for large packaging of batteries, the limiting gap of the battery on the tray device is uniformly arranged, and the size of the limiting gap can be adjusted. The limiting gap after adjustment is still equidistant, and can be flexibly compatible with large packaging incoming battery with a size of 1000*1200 mm. A series of code scanning, testing, NG discharge, turning, gluing and other work can be performed on the tray device.

[0081] The tray device of the present application can be compatible with batteries of multiple sizes, and can realize quick model switching in different working states without human intervention, and can realize model switching by directly switching the program; after the battery is placed in the limiting gap, the size of the limiting gap can be automatically adjusted to compensate for the large deviation of the clamp.

[0082] The above only describes preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
