Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0051] The technical solution of this application is clearly and completely described below with reference to the drawings.

[0052] Please refer to Figure 1 , which is a schematic diagram of the structure of a high-temperature vacuum baking line 100 according to an embodiment of the present application. The high-temperature vacuum baking line 100 includes a loading device 10, a baking oven 20, an unloading device 30, a conveyor rail 40, a handling robot 50 for handling materials, and a transfer cart 60 for carrying materials. The materials described in this embodiment of the application are battery cell fixtures loaded with battery cells.

[0053] Reference Figure 1 The loading device 10, the baking oven 20, and the unloading device 30 are arranged in sequence along the conveying rail 40, thereby forming an assembly line for loading, baking, and unloading materials. The handling robot 50 is arranged on the conveying rail 40. The handling robot 50 can move along the conveying rail 40 to transfer the battery cell clamps from the loading device 10 to the baking oven 20, and transfer the battery cell clamps in the baking oven 20 to the unloading device 30. The transfer trolley 60 is arranged on the conveying rail 40 and can move along the conveying rail 40. The handling robot 50 can transfer the battery cell clamps on the loading device 10 to the baking oven 20, and can transfer the battery cell clamps in the baking oven 20 to the transfer trolley 60. At the same time, the handling robot 50 can also transfer the battery cell clamps on the transfer trolley 60 to the baking oven 20.

[0054] Through the cooperation of the handling robot 50 and the transfer trolley 60, simultaneous transfer of loading and moving of materials can be achieved, which improves the transportation efficiency of the battery cell fixtures, facilitates the recycling of the battery cell fixtures, and increases the equipment production capacity.

[0055] In one embodiment of the present application, a loading device 10, a baking oven 20, and an unloading device 30 are provided on both sides of a conveyor track 40. Together with a handling robot 50 and a transfer cart 60, they increase the production capacity of the high-temperature vacuum baking line 100. Furthermore, multiple baking ovens 20 are provided on both sides of the conveyor track 40. These baking ovens 20 are spaced apart along the conveyor track 40, enabling simultaneous baking in multiple baking ovens 20 and improving the baking line's production capacity.

[0056] There are two ways for the transfer trolley 60 and the transport robot 50 to move: one is that the transfer trolley 60 and the transport robot 50 move synchronously along the conveying rail 40; the other is that the transfer trolley 60 and the transport robot 50 move separately. The implementation scheme of the transfer trolley 60 and the transport robot 50 moving is as follows:

[0057] In one embodiment of the present application, the transfer trolley 60 is detachably connected to the handling robot 50. When the transfer trolley 60 is connected to the handling robot 50, the handling robot 50 can drive the transfer trolley 60 to move along the conveying guide rail 40. In this case, the handling robot 50 and the transfer trolley 60 share the walking mechanism of the handling robot 50. The transfer trolley 60 is driven by the handling robot 50 to move. The handling robot 50 carries one material and the transfer trolley 60 carries one material, thereby achieving simultaneous handling of two materials, high handling efficiency, reduced power drive, and reduced costs. When the transfer trolley 60 is separated from the handling robot 50, the transfer trolley 60 can move independently on the conveying guide rail 40. The handling robot 50 can carry the battery cell clamps on the loading device 10 into the baking oven 20, and can carry the battery cell clamps in the baking oven 20 onto the transfer trolley 60. In this case, the battery cell clamps can be transferred while loading and moving the materials, thereby improving the circulation efficiency of the battery cell clamps.

[0058] In one embodiment of the present application, the transfer trolley 60 is provided with a first walking chassis (not shown in the figure), which can drive the transfer trolley 60 to move along the conveying guide rail 40; the handling robot 50 is provided with a second walking chassis (not shown in the figure), which can drive the handling robot 50 to move along the conveying guide rail 40. The transfer trolley 60 and the handling robot 50 are respectively provided with walking chassis, so that the transfer trolley 60 can move independently of the handling robot 50, thereby improving the walking flexibility of the transfer trolley 60, facilitating the division of labor between the transfer trolley 60 and the handling robot 50, and improving the flexibility of material transportation. For example, after the battery cell fixture is baked, the handling robot 50 can place the baked battery cell fixture on the transfer trolley 60, and the transfer trolley 60 will deliver the battery cell fixture to the unloading device 30. At the same time, the handling robot 50 can move to the loading device 10 to pick up materials from the loading device 10, so as to realize the division of labor and cooperation between the transfer trolley 60 and the handling robot 50.

[0059] Please refer to Figure 2 , which is a schematic structural diagram of a transfer trolley 60 according to an embodiment of the present application. The transfer trolley 60 includes a frame 61, a first roller conveying mechanism 62, a first transfer limit plate 63, a second transfer limit plate 64, a first lifting mechanism 65, a second lifting mechanism 66, a first limit drive mechanism 67, and a second limit drive mechanism 68.

[0060] The carriage 61 is slidably disposed on the conveying rail 40 , and the carriage 61 can move along the conveying rail 40 .

[0061] The first roller conveyor mechanism 62 is mounted on the vehicle frame 61 and is capable of receiving and conveying battery cell fixtures. When a battery cell fixture is transferred to the transfer vehicle 60, it is placed on the rollers of the first roller conveyor mechanism 62. When the battery cell fixture needs to be transported, the first roller conveyor mechanism 62 can transport the battery cell fixture, with the conveying direction of the first roller conveyor mechanism 62 being perpendicular to the conveying guide rail 40. The first roller conveyor mechanism 62 is capable of receiving and conveying battery cell fixtures to facilitate their transport. The conveying direction of the first roller conveyor mechanism 62 is perpendicular to the conveying guide rail 40, facilitating docking with the loading device 10 or unloading device 30.

[0062] Both the first transfer limit plate 63 and the second transfer limit plate 64 are movably mounted on the vehicle frame 61. The first transfer limit plate 63 and the second transfer limit plate 64 are located on both sides of the vehicle frame 61 in a direction perpendicular to the conveying guide rail 40. A first lifting mechanism 65 and a second lifting mechanism 66 are mounted on the vehicle frame 61. The first lifting mechanism 65 is capable of driving the first transfer limit plate 63 to rise and fall relative to the vehicle frame 61 to dock with or separate from the first roller conveying mechanism 62. The second lifting mechanism 66 is capable of driving the second transfer limit plate 64 to rise and fall relative to the vehicle frame 61 to dock with or separate from the first roller conveying mechanism 62. When the first lifting mechanism 65 lifts the first transfer limit plate 63 to dock with the first roller conveying mechanism 62, and the second lifting mechanism 66 lifts the second transfer limit plate 64 to dock with the first roller conveying mechanism 62, the first limit drive mechanism 67 can cooperate with the second limit drive mechanism 68 to jointly clamp the battery cell clamp located on the first roller conveying mechanism 62 to ensure that the battery cell clamp is limited when the transfer trolley 60 moves.

[0063] like Figure 2As shown, the first transfer limiting plate 63 includes a first base plate 631 and a first limiting portion 632. The first base plate 631 is parallel to the first roller conveying mechanism 62. The first limiting portion 632 is arranged perpendicular to the first base plate 631 and located above the first base plate 631. The first limiting portion 632 is located at the end of the first base plate 631 away from the second transfer limiting plate 64. The first limiting driving mechanism 67 is mounted on the first limiting portion 632. The second transfer limiting plate 64 includes a second base plate 641 and a second limiting portion 642. The second base plate 641 is parallel to the first roller conveying mechanism 62. The second limiting portion 642 is arranged perpendicular to the second base plate 641 and located above the second base plate 641. The second limiting portion 642 is located at the end of the second base plate 641 away from the first transfer limiting plate 63. The second limiting driving mechanism 68 is mounted on the second limiting portion 642.

[0064] In an optional embodiment of the present application, both the first lifting mechanism 65 and the second lifting mechanism 66 utilize pneumatic cylinders, which drive the first transfer limit plate 63 and the second transfer limit plate 64 to move upward and downward flexibly. The first limit drive mechanism 67 and the second limit drive mechanism 68 utilize pneumatic cylinders, with limit blocks (not shown) provided at the ends of the telescopic rods of the cylinders, which contact the battery cell fixture via the limit blocks.

[0065] The working principle of transfer trolley 60 is:

[0066] The battery cell fixture is loaded at the loading device 10 station: when the loading device 10 located on the side of the first transfer limit plate 63 loads the battery cell fixture to the transfer trolley 60, the second transfer limit plate 64 is driven by the second lifting mechanism 66 to rise to the second substrate 641 and be flush with the roller of the first roller conveying mechanism 62, so that the second substrate 641 can receive the battery cell fixture; as the battery cell fixture moves on the first roller conveying mechanism 62, the battery cell fixture is blocked by the second limit part 642, and the first roller conveying mechanism 62 stops driving; the first lifting mechanism 65 drives the first transfer limit plate 63 to rise to the first substrate 631 to receive the battery cell fixture; the first limit drive mechanism 67 drives the corresponding limit block to extend, and the second limit drive mechanism 68 drives the corresponding limit block to extend, so that the limit blocks of the two limit drive mechanisms act together on the battery cell fixture to achieve the limitation of the battery cell fixture and complete the loading of the battery cell fixture.

[0067] It should be pointed out that when the loading device 10 located on the side of the second transfer limit plate 64 loads the battery cell clamp to the transfer cart 60, the first transfer limit plate 63 first rises and carries the battery cell clamp. After the battery cell clamp moves to abut against the first limit part 632, the second transfer limit plate 64 rises again. The remaining operations are the same as the above-mentioned operations when the loading device 10 located on the side of the first transfer limit plate 63 is docked with the transfer cart 60.

[0068] Unloading the battery cell clamp at the baking oven station 20: When the transfer trolley 60 moves the battery cell clamp of the loading device 10 to the baking oven station 20, the first limit drive mechanism 67 and the second limit drive mechanism 68 release the limit on the battery cell clamp, and the handling robot 50 transfers the battery cell clamp on the first roller conveying mechanism 62 to the baking oven 20, completing the loading of the battery cell clamp from the transfer trolley 60 to the baking oven 20.

[0069] The battery cell clamp is loaded at the baking oven 20 station: the handling robot 50 transfers the baked battery cell clamp in the baking oven 20 to the first roller conveying mechanism 62, the first limit drive mechanism 67 and the second limit drive mechanism 68 limit the battery cell clamp, and the transfer trolley 60 transfers the battery cell clamp toward the unloading device 30.

[0070] Unloading the battery cell fixture at the unloading device 30 station: After the transfer trolley 60 moves to the unloading device 30 station, the first limit drive mechanism 67 and the second limit drive mechanism 68 release the limit on the battery cell fixture. According to the position of the unloading device 30 relative to the conveying guide rail 40, the transfer limit plate on the side corresponding to the unloading position descends, and the first roller conveying mechanism 62 conveys the battery cell fixture to the unloading device 30, completing the unloading of the battery cell fixture from the transfer trolley 60 to the unloading device 30.

[0071] Furthermore, guide balls 633 are provided on both the first substrate 631 and the second substrate 641, and the guide balls 633 are arranged at intervals along the conveying direction of the first roller conveying mechanism 62, so as to reduce the friction between the battery cell clamp and the first substrate 631 or the second substrate 641 when the first roller conveying mechanism 62 conveys the battery cell clamp.

[0072] It should be pointed out that while the transfer trolley 60 is loading, unloading or transferring the battery cell clamps, the handling robot 50 can also load, unload or transfer the battery cell clamps, thereby realizing loading (which may include loading the transfer trolley 60, loading the baking oven 20 and loading the unloading device 30) and transferring the battery cell clamps at the same time, thereby improving the battery cell clamp circulation efficiency.

[0073] Please refer to Figure 3 , which is a schematic diagram of the structure of a feeding device 10 according to an embodiment of the present application. The feeding device 10 includes an incoming material pull belt 11, an incoming material code scanning mechanism 12, a CCD camera 13, a flipping mechanism 14, a feeding robot 15, a feeding tool 16, a feeding buffer tool 17, a failed material buffer pull belt 18, and a feeding transfer tool 19.

[0074] The incoming material pull belt 11 can take over the battery cell fixtures conveyed by the previous process. The incoming material scanning mechanism 12 is used to scan the battery cells conveyed by the incoming material pull belt 11 to record the battery cell information. The CCD camera 13 can take pictures of the battery cell fixtures conveyed by the incoming material pull belt 11 to detect the battery cell fixtures. When unqualified battery cell fixtures are detected, the loading robot 15 transfers the unqualified battery cell fixtures to the unqualified buffer pull belt 18. The unqualified buffer pull belt 18 is used to transport unqualified battery cell fixtures to the unqualified storage station. The flipping mechanism 14 is used to flip the battery cell fixture so that the CCD camera 13 can detect the two opposite detection surfaces of the battery cell fixture. The loading robot 15 can also transfer qualified battery cell fixtures to the loading fixture 16 and the loading buffer fixture 17. The loading robot 15 preferably transfers the battery cell fixture to the loading fixture 16. After the loading fixture 16 has reached its capacity, the battery cell fixture is transferred to the loading buffer fixture 17 for storage. The loading transfer tool 19 is used to dock with the transfer trolley 60 to facilitate the loading of battery cell fixtures from the loading device 10 to the transfer trolley 60.

[0075] like Figure 4 As shown, the loading transfer tooling 19 includes a second roller conveying mechanism 191, a loading frame 192, a first loading limit plate 193, a second loading limit plate 194, a third lifting mechanism 195, a fourth lifting mechanism 196, and a third limit driving mechanism 197.

[0076] The second roller conveyor mechanism 191 is mounted on the loading frame 192 and is capable of receiving and conveying battery cell fixtures. When the loading robot 15 transfers the battery cell fixtures to the loading transfer tooling 19, the battery cell fixtures are placed on the rollers of the second roller conveyor mechanism 191. When the battery cell fixtures need to be transported, the second roller conveyor mechanism 191 can transport them, with the conveying direction of the second roller conveyor mechanism 191 being perpendicular to the conveying guide rails 40. The second roller conveyor mechanism 191 is capable of receiving and conveying battery cell fixtures to facilitate their transport; the conveying direction of the second roller conveyor mechanism 191 is perpendicular to the conveying guide rails 40, facilitating docking with the transfer cart 60.

[0077] The first loading limit plate 193 and the second loading limit plate 194 are both movably disposed on the loading frame 192. The first loading limit plate 193 and the second loading limit plate 194 are distributed on both sides of the loading frame 192 in a direction perpendicular to the conveying guide rail 40, and the first loading limit plate 193 is disposed near the conveying guide rail 40. The first loading limit plate 193 includes a third base plate 1931 and a third limiting portion 1932. The third base plate 1931 is parallel to the second roller conveying mechanism 191. The third limiting portion 1932 is disposed perpendicular to the third base plate 1931 and is located above the third base plate 1931. The third limiting portion 1932 is located at an end of the third base plate 1931 away from the second loading limit plate 194. The second loading limit plate 194 includes a fourth substrate 1941 and a fourth limiting portion 1942. The fourth substrate 1941 is parallel to the second roller conveying mechanism 191. The fourth limiting portion 1942 is arranged perpendicular to the fourth substrate 1941 and is located above the fourth substrate 1941. The fourth limiting portion 1942 is located at the end of the fourth substrate 1941 away from the first loading limit plate 193.

[0078] The third and fourth lifting mechanisms 195 and 196 are mounted on the loading frame 192. The third lifting mechanism 195 is capable of driving the first loading limit plate 193 to move upward or downward relative to the loading frame 192 to engage or disengage with the second roller conveying mechanism 191. The fourth lifting mechanism 196 is capable of driving the second loading limit plate 194 to move upward or downward relative to the loading frame 192 to engage or disengage with the second roller conveying mechanism 191. The third position-limiting driving mechanism 197 is mounted on the fourth position-limiting portion 1942 and is a pneumatic cylinder.

[0079] The working principle of the loading transfer tooling 19 is:

[0080] After the loading robot 15 places the battery cell clamp on the roller of the second roller conveying mechanism 191, the third lifting mechanism 195 lifts the first loading limit plate 193 to dock with the second roller conveying mechanism 191, and the second roller conveying mechanism 191 drives the battery cell clamp to move toward the conveying guide rail 40 until the battery cell clamp abuts against the third limit part 1932. The third limit part 1932 can block the battery cell clamp from moving toward the conveying guide rail 40, and the second roller conveying mechanism 191 stops working; the fourth lifting mechanism 196 lifts the second loading limit plate 194 to dock with the second roller conveying mechanism 191, and the third limit drive mechanism 197 works. The third limit drive mechanism 197 cooperates with the third limit part 1932 to clamp the battery cell clamp to achieve deviation correction and limitation of the battery cell clamp. After the transfer trolley 60 is docked with the loading transfer transmission work (such as Figure 5 and Figure 6As shown), the third limit drive mechanism 197 releases the limit on the battery cell clamp 70, the third lifting mechanism 195 and the fourth lifting mechanism 196 respectively drive the first loading limit plate 193 and the second loading limit plate 194 to descend, the second roller conveying mechanism 191 drives the battery cell clamp 70 to move toward the transfer trolley 60, the battery cell clamp 70 moves to the first roller conveying mechanism 62, and is gradually loaded onto the transfer trolley 60 under the action of the first roller conveying mechanism 62.

[0081] In order to improve the transfer efficiency of the battery cell fixture, when the transfer cart 60 is docked with the loading transfer tooling 19, the handling robot 50 takes materials from the loading tooling 16, and the transfer cart 60 takes materials from the loading transfer tooling 19, which improves the flexibility of the battery cell fixture transfer.

[0082] Please refer to Figure 7 , which is a schematic diagram of the structure of a blanking device 30 shown in an embodiment of the present application. The blanking device 30 includes a blanking transfer tool 31, a blanking robot 32, a blanking tool 33, a blanking pull belt 34, and a buffer pull belt 35 for blanking unqualified batteries.

[0083] The unloading transfer tooling 31 is used to dock with the transfer trolley 60 to realize the unloading of the baked battery cell fixture from the transfer trolley 60 to the unloading transfer tooling 31. The unloading robot 32 is used to transfer the battery cell fixture on the unloading transfer tooling 31 to the unloading tooling 33, and the unloading tooling 33 realizes the storage of the battery cell fixture. The unloading robot 32 can also transfer the battery cell fixture on the unloading tooling 33 to the unloading pull belt 34. The unloading pull belt 34 is provided with an unloading code scanning mechanism (not shown in the figure), and the battery cell fixture is scanned by the unloading code scanning mechanism and then transported to the next station via the unloading pull belt 34. After the unloading robot 32 finds an unqualified battery cell fixture, it sends the unqualified battery cell fixture to the unqualified unloading battery cell buffer pull belt 35, and the unqualified unqualified battery cell buffer pull belt 35 is transported to the unqualified storage station.

[0084] The unloading transfer tool 31 includes a third roller conveyor mechanism, an unloading frame, a first unloading stop plate, a second unloading stop plate, a fifth lifting mechanism, a sixth lifting mechanism, and a fourth limit drive mechanism. The structure of the unloading transfer tool 31 is identical to that of the loading transfer tool 19. The detailed structure of the components of the unloading transfer tool 31 is omitted here; please refer to the structure of the loading transfer tool 19 for details.

[0085] The third roller conveyor mechanism is mounted on the unloading frame and is capable of receiving and transporting battery cell fixtures. When the transfer cart 60 docks with the unloading transfer tooling 31, the battery cell fixtures are transferred to the third roller conveyor mechanism driven by the first roller conveyor mechanism 62. The conveying direction of the third roller conveyor mechanism is perpendicular to the conveyor rails 40. The third roller conveyor mechanism is capable of receiving and transporting battery cell fixtures, facilitating their transport. The conveying direction of the third roller conveyor mechanism is perpendicular to the conveyor rails 40, facilitating docking with the transfer cart 60.

[0086] The working principle of the unloading transfer tooling 31 is similar to that of the loading transfer tooling 19 and will not be described in detail in this application.

[0087] After the cell fixture is transferred to the unloading transfer tooling 31, the unloading robot 32 transfers the cell fixture to the unloading tooling 33 for storage. Simultaneously, the unloading robot 32 transfers the cell fixture from the unloading tooling 33 to the unloading belt 34 to complete the unloading process. While the transfer cart 60 docks with the unloading transfer tooling 31, the handling robot 50 unloads the cell fixture onto the unloading tooling 33, improving unloading efficiency.

[0088] It should be noted that the handling robot 50, loading robot 15, and unloading robot 32 in the embodiment of the present application are all six-axis robots with a large number of degrees of freedom, which facilitates the flexible handling of battery cell fixtures and improves handling efficiency. While the handling robot 50 is loading and moving materials, the transfer cart 60 can transfer battery cell fixtures, improving the recycling efficiency of battery cell fixtures.

[0089] According to the high-temperature vacuum baking line 100 of the embodiment of the present application, the handling robot 50 and the transfer trolley 60 operate together to transfer, so that two battery cell fixtures can be circulated at one time, with high cycle efficiency and high equipment production capacity.

[0090] The present application also provides a material baking production method, which uses the above-mentioned high-temperature vacuum baking line 100. The material baking production method includes:

[0091] Preparation before baking: The transport robot 50 and the transfer trolley 60 transport the materials to be baked on the loading device 10 to the baking oven 20, and the transport robot 50 transports the materials to be baked into the baking oven 20;

[0092] Material baking: the baking oven 20 bakes the material to be baked located in the baking oven 20;

[0093] Unloading after baking: The transport robot 50 transports the baked materials in the baking oven to the transfer trolley 60, which moves to dock with the unloading device 30 and transfers the baked materials to the unloading device 30 for unloading;

[0094] Repeat the above steps until all materials are baked;

[0095] In which, while the transfer trolley 60 transports the baked materials to the unloading device 30 for unloading, the transport robot 50 can transport the materials to be baked to the empty baking oven 20.

[0096] It should be pointed out that the above-mentioned material baking production method is a method shown in an embodiment of the present application, and the high-temperature vacuum baking line 100 of the present application may also have other material baking production methods.

[0097] In one embodiment of the present application, when the transfer trolley 60 moves to the unloading device 30 to unload materials, the transport robot 50 can also transport materials to the unloading device 30 to unload materials, thereby improving the unloading efficiency of the materials.

[0098] In one embodiment of the present application, in the early stage of baking, the transfer cart 60 and the transport robot 50 move between the baking oven 20 and the loading device 10 to transport the materials to be baked on the loading device 10 to the baking oven 20 to improve the loading efficiency of the baking oven 20.

[0099] It should be noted that, unless there is any conflict, the features in the embodiments of this application can be combined with each other.

[0100] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
