Description

Technical Field

[0001] This invention relates to the field of battery moving device technology, specifically to a battery moving locking device and system. Background Technology

[0002] With the development of society and the economy, and the improvement of people's living standards, cars are becoming increasingly common in households.

[0003] This has led to a year-on-year increase in car ownership, which in turn has made environmental pollution problems more prominent. Therefore, in order to build a low-carbon and environmentally friendly economy and develop a new energy strategy, as well as with the increasing maturity of electric vehicle technology, major cities are increasing their efforts to promote the application of electric vehicles. The fundamental aspect of the development of electric vehicles lies in the revolution of battery technology. Currently, the conventional battery with stable performance and high energy density is the lithium battery, so lithium batteries have naturally become the mainstream choice for electric vehicles.

[0004] The processing of lithium batteries generally includes slurry preparation, coating, rolling, slitting, assembly, capacity testing, and formation. Among these process steps, capacity testing and formation are crucial to the performance and quality of the battery. Existing technologies typically use trays to support and fix lithium batteries before sending them to capacity testing and formation cabinets for testing.

[0005] The existing tray technology has the following disadvantages:

[0006] 1. Insufficient positioning accuracy: During battery transportation, due to the lack of an effective locking mechanism, the battery may move on the tray, causing physical damage to the surface, such as scratches or deformation of the battery surface, or even leading to poor contact or inaccurate results during testing.

[0007] 2. Low production efficiency: The existing pallet clamping process is time-consuming and inefficient, making it difficult to meet the needs of rapid production;

[0008] 3. Low level of automation: The existing pallet locking and unlocking mechanisms may not be able to seamlessly integrate with automated systems, limiting the level of automation in the overall production process. Summary of the Invention

[0009] The technical problem to be solved by this invention is how to improve positioning accuracy and enable rapid unlocking.

[0010] The present invention solves the above-mentioned technical problems through the following technical means:

[0011] The first aspect of the present invention provides a battery moving locking device, including a locking mechanism capable of locking the battery in place, unlocking mechanisms capable of unlocking the locking mechanism provided on both sides of the locking mechanism, a pushing mechanism capable of locking the locking mechanism and a pressing block lifting mechanism capable of maintaining the locking mechanism in a locked state provided at the end of the locking mechanism.

[0012] Beneficial effects: This invention locks the battery by placing it in a locking mechanism and locking it with a pushing mechanism, preventing the battery from shaking during transportation and testing, effectively improving the accuracy of battery positioning, and preventing poor contact between the probe and the battery in subsequent formation, capacity grading and other processes, thus effectively improving the stability of test results; then, the locking state is maintained by a pressing and lifting mechanism to ensure the battery remains stable when moving; when unlocking is required, the unlocking mechanism and the locking mechanism work together to unlock the battery for loading or unloading.

[0013] Preferably, the locking mechanism includes an end plate, a side plate, and a partition plate. The end plate and the side plate are connected to form a frame of the locking mechanism. Multiple partition plates are provided inside the frame, and the multiple partition plates form a cavity that can accommodate the battery. The end plate includes a first end plate with a through hole. A connecting plate is provided between the first end plate and the partition plate. The connecting plate is connected to the partition plate. The multiple partition plates are connected by a guide rod. The two ends of the partition plate are provided with fixing holes.

[0014] Beneficial effects: The present invention connects multiple partitions through guide rods, allowing the partitions to move within the guide rods. The pushing force of the jacking mechanism compresses the partitions, thereby reducing the cavity space that accommodates the battery and locking the battery within the cavity, thus achieving battery locking.

[0015] Preferably, the unlocking mechanism includes a base plate, an unlocking component disposed on top of the base plate, and a cover plate covering the top of the unlocking component. The bottom of the cover plate is provided with a protrusion, which engages with a groove in the unlocking component.

[0016] Beneficial effects: The present invention provides a protrusion on the cover plate that engages with the groove of the unlocking component, ensuring that the unlocking component can move stably in a straight line on the base plate and guaranteeing the stable operation of the unlocking component.

[0017] Preferably, the unlocking component includes an unlocking head and an unlocking block. The unlocking head is connected to the unlocking block and engages with a fixing hole. The top of the unlocking block is provided with a groove. The unlocking block is provided with a hook and a limiting groove. Multiple unlocking blocks are connected by engaging the hook and the limiting groove.

[0018] Beneficial effects: This invention connects multiple unlocking blocks by engaging the unlocking head and the fixing hole, and connecting the unlocking head to the unlocking block. The unlocking block is equipped with hooks and limiting grooves, allowing multiple partitions to unfold sequentially. This invention achieves maximum limiting through the engagement of the hooks and limiting grooves, ensuring that the cavity spaces formed by the unlocked partitions are of uniform size, thus maximizing the space within the cavity and achieving the unlocking purpose.

[0019] Preferably, the unlocking component further includes an end block, which is fixed to the top of the base plate and the lower surface of the cover plate. The end block is divided into a first end block and a second end block. The first end block is provided with a limiting groove and is connected to the hook of the unlocking block at one end of the unlocking component. The second end block is fixed to the other end of the unlocking component.

[0020] Beneficial effects: The present invention provides end blocks at both ends of the unlocking component for supporting the cover plate. The purpose of providing the first end block is to fix one end of the unlocking component so that the unlocking component can be compressed or unfolded along one side.

[0021] Preferably, the top of the base plate is provided with a slide rail, and the bottom of the unlocking block is provided with a protrusion that engages with the slide rail, and the slide rail engages with multiple unlocking blocks.

[0022] Beneficial effects: The slide rail of this invention makes the compression or unfolding of the unlocking component smoother and reduces resistance.

[0023] Preferably, the unlocking mechanism further includes an actuation component, which includes a first cylinder and a connecting block. The connecting block is connected to an unlocking block at one end of the unlocking component, and the telescopic end of the first cylinder is connected to the connecting block.

[0024] Beneficial effects: By setting up an action component, the present invention can drive the unlocking component to move linearly on the base plate, so that the unlocking head can engage with the fixing hole to complete the unfolding and unlocking action of the partition.

[0025] Preferably, the unlocking mechanism includes a second cylinder, which is fixed to the base plate.

[0026] Beneficial effects: By setting a second cylinder in the unlocking mechanism, the present invention provides the unlocking mechanism with the power to push and pull inward and outward, so that the unlocking head can engage with or be pulled out of the fixing hole.

[0027] Preferably, the pushing mechanism includes a pushing cylinder and a blocking cylinder, which are respectively disposed at the end of the locking mechanism. The extension end of the pushing cylinder is provided with a pushing column, which can pass through the through hole of the first end plate and connect to the connecting plate. The blocking cylinder is provided with a blocking block.

[0028] Beneficial effects: The present invention uses a push cylinder to push the push column through the through hole of the first end plate and contact the connecting plate. Then, a blocking cylinder fixes the other end of the locking mechanism through the blocking block. The push cylinder further provides power, and the partition is pushed and moves the guide rod to the other end, which reduces the cavity space containing the battery, thereby achieving the purpose of locking the locking mechanism and ensuring that the position of the battery inside its cavity does not change.

[0029] Preferably, the pressing block lifting mechanism includes a pressing block and a lifting mechanism, wherein the pressing block is placed in a frame locked by a locking mechanism via the lifting mechanism.

[0030] Beneficial effects: The present invention uses a pushing mechanism to compress and lock the locking mechanism, and then uses a lifting mechanism to place the pressure block in the frame of the locked mechanism, ensuring that the locking mechanism remains locked.

[0031] Preferably, the pressure block has a fastening groove at the top and a U-shaped groove at the bottom; the lifting mechanism includes a bracket, with a push-pull cylinder and a lifting cylinder fixed on both sides of the bracket, the extension end of the lifting cylinder being connected to the clamping cylinder, the clamping cylinder having a gripper, and the gripper engaging with the fastening groove.

[0032] Beneficial effects: The present invention enables the lifting mechanism to move the pressure block by engaging the clamping jaws of the clamping cylinder with the fastening groove.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0048] Example 1

[0049] according to Figure 9As shown, this embodiment provides a battery moving lock clamp device, including a locking mechanism 10 that can lock the battery in place, an unlocking mechanism 20 that can unlock the locking mechanism 10 is provided on both sides of the locking mechanism 10, a pushing mechanism 30 that can lock the locking mechanism 10 and a pressing block lifting mechanism 40 that can maintain the locking mechanism 10 in a locked state are provided at the end of the locking mechanism 10.

[0050] In this embodiment, the battery is placed in the locking mechanism 10 and locked by the pushing mechanism 30, thus achieving a locking effect. This prevents the battery from shaking during transportation and testing, effectively improving the positioning accuracy of the battery. In subsequent formation, capacity grading and other processes, it prevents poor contact between the probe and the battery, effectively improving the stability of the test results. Then, the locking state is maintained by the pressing block lifting mechanism 40 to ensure that the battery remains stable when moving. When unlocking is required, the unlocking mechanism 20 is combined with the locking mechanism 10 to unlock the battery before loading or unloading.

[0051] See also Figure 1-8 The locking mechanism 10 includes an end plate, a side plate, and a partition plate 14. The end plate and side plate are connected to form a rectangular frame of the locking mechanism 10. Multiple partition plates 14 are disposed inside the rectangular frame. Each partition plate 14 has fixing holes 141 at both ends. Figure 1-3 As shown, each pair of adjacent partitions 14 can form multiple sealed cavities 16 that can accommodate batteries. The multiple partitions 14 are connected by passing through guide rods 13. The partitions 14 can slide on the surface of the guide rods 13. The two ends of the guide rods 13 are connected to end plates. Adjacent partitions 14 positioned on the guide rods 13 can be merged together by external force to form sealed cavities 16 that lock the batteries. They can also be separated by a certain distance by external force. This certain distance is the cavity 16 that can accommodate or remove the batteries without causing them to fall out. The external force refers to the locking action brought by the pushing mechanism 30 or the unlocking action brought by the unlocking mechanism 20.

[0052] The end plate includes a first end plate 11. A connecting plate 12 is provided between the first end plate 11 and the partition 14. The connecting plate 12 is connected to the partition 14 but not to the first end plate 11. The first end plate 11 has a through hole 111. The pushing mechanism 30 contacts the connecting plate 12 by passing through the through hole 111. The pushing mechanism 30 provides a pushing force, which is transmitted to the partition 14 through the connecting plate 12. The partition 14 moves to one end by the pushing force, thereby compressing the cavity 16 space formed between the partitions 14, so that the battery cannot shake in the cavity 16, thereby achieving the purpose of locking the locking mechanism 10.

[0053] The unlocking mechanism 20 includes a base plate 21, an unlocking component 22 disposed on the top of the base plate 21, and a cover plate 23 covering the top of the unlocking component 22. The bottom of the cover plate 23 is provided with a protrusion 231, which engages with the groove 222a in the unlocking component, so that the unlocking component 22 can move in a straight line on the base plate, ensuring the stable operation of the unlocking component 22.

[0054] The unlocking component 22 includes an unlocking head 221 and an unlocking block 222. The unlocking head 221 is connected to the unlocking block 222. The unlocking head 221 engages with the fixing hole 141. By connecting the unlocking head 221 to the unlocking block 222, the partition 14 unfolds and unlocks in sequence. The cavity 16 formed by the unlocked partition 14 has the same size.

[0055] The unlocking block 222 has a groove 222a on its top. The unlocking block 222 also has a hook 222c and a limiting groove 222d. The hook 222c and the limiting groove 222d can engage to connect multiple unlocking blocks 222 together, forming the entire unlocking assembly 22. The number of unlocking heads 221 is the same as the number of unlocking blocks 222, and the number of unlocking heads 221 is the same as the number of partitions 14. The engagement of the hook 222c and the limiting groove 222d allows the cavity 16 to reach its maximum space, which is the unlocked state.

[0056] The unlocking head 221 is fixed to the unlocking body 222e of the unlocking block 222 by bolts. Its shape is "convex" and the surface edge is chamfered. The purpose is to make it easier and more efficient for the unlocking head 221 to engage with the fixing hole 141 of the locking mechanism 10, and to ensure the stability of the unlocking action.

[0057] The unlocking mechanism 20 further includes an action component 24, which includes a first cylinder 241 and a connecting block 242. The connecting block 242 is connected to the unlocking block 222 at one end of the unlocking component 22. The telescopic end of the first cylinder 241 is connected to the connecting block 242. The compression and expansion of the unlocking component 22 are achieved by the telescopic movement of the first cylinder 241. When the unlocking head 221 engages with the fixing hole 141, the first cylinder 241 provides power to unlock the locking mechanism 10, causing the multiple partitions 14 to separate and the cavity 16 to reach its maximum space. At this time, the locking mechanism 10 completes the unlocking action.

[0058] To better secure the unlocking block 222, end blocks are provided at both ends of the unlocking assembly 22. These end blocks are divided into a first end block 251 and a second end block 252. Both end blocks are fixed to the top of the base plate 21 and the lower surface of the cover plate 23, serving to support the cover plate 23. The first end block 251 has a groove on its top, which engages with the protrusion 231 of the cover plate 23. The first end block 251 also has a limiting groove 222d, allowing it to connect with the hook 222c of the unlocking block 222 at one end of the unlocking assembly 22. The second end block 252 is fixed to the other end of the unlocking assembly 22, thus forming the entire unlocking assembly 22. The first end block 251 secures the unlocking block 222 at one end, ensuring that during the unlocking and unfolding process, keeping one end fixed allows all cavities 16 to reach their maximum limit and maintains consistent spacing between cavities 16.

[0059] In order to enable the unlocking component 22 to compress and unfold more smoothly, this embodiment provides a slide rail 26 at the bottom of the unlocking component 22. The slide rail 26 is located on the top of the base plate 21. The bottom of the unlocking block 222 is provided with a corresponding protrusion 222b. The protrusion 222b cooperates with the slide rail 26 to make the unlocking component 22 compress and unfold more smoothly and reduce resistance.

[0060] The unlocking mechanism 20 is further provided with a second cylinder 27, which is fixed in the middle of the base plate 21. The second cylinder 27 provides the unlocking mechanism 20 with the power to push and pull inward and outward. When the locking mechanism 10 needs to be unlocked, the second cylinder 27 moves the unlocking mechanism 20 from both sides toward the locking mechanism 10, so that the unlocking head 221 engages with the fixing hole 141. When unlocking is completed, the second cylinder 27 moves the unlocking mechanism 20 away from the locking mechanism 10 to both sides, so that the unlocking head 221 separates from the fixing hole 141.

[0061] The pushing mechanism 30 includes a pushing cylinder 31 and a blocking cylinder 32. The pushing cylinder 31 and the blocking cylinder 32 are respectively disposed at the ends of the locking mechanism 10. The pushing cylinder 31 is disposed on the side of the first end plate 11. The telescopic end of the pushing cylinder 31 is provided with a pushing column 34. The pushing column 34 can pass through the through hole 111 of the first end plate 11 and connect to the connecting plate 12. At this time, the pushing cylinder 31 provides a thrust, which can compress the cavity 16. The blocking cylinder 32 is provided with a blocking block 33. The blocking block 33 blocks the other end, so that the cavity 16 can be compressed at this end.

[0062] In this embodiment, the push cylinder 31 is equipped with multiple push columns 34, which are cylindrical in shape. When the push cylinder 31 pushes forward, it drives the push columns 34 to move synchronously. The position and size of the push columns 34 match the through holes 111 of the first end plate 11, so that the push columns 34 pass through the first end plate 11, contact the connecting plate 12, and continue to apply a pushing force to the partition 14. At the same time, the blocking cylinder 32 provides the opposite force through the blocking block 33. The shape and size of the blocking block 33 match the end of the rectangular frame to ensure sufficient contact area to achieve the blocking effect. The two work together to ensure that the rectangular frame of the locking mechanism 10 is fixed in position, and the partition 14 is pushed, based on the inward displacement of the guide rod 13, until the internal cavity 16 of the partition 14 is compressed to the minimum, so as to lock the locking mechanism 10, and all of them are moved to one end of the rectangular frame.

[0063] The pressing block lifting mechanism 40 includes a pressing block 41 and a lifting mechanism 42. The pressing block 41 is placed in the rectangular frame locked by the locking mechanism 10 through the lifting mechanism 42, so as to keep the locking mechanism 10 locked and ensure that the battery position does not change during the movement.

[0064] The pressure block 41 has a fastening groove 411 at the top and a U-shaped groove 412 at the bottom. The lifting mechanism 42 includes a bracket 422, on both sides of which a push-pull cylinder 423 and a lifting cylinder 421 are fixed. The clamping cylinder 424 is fixed below and connected to the lifting cylinder 421. The clamping cylinder 424 also has a gripper 424a, which engages with the fastening groove 411 to move the pressure block 41.

[0065] The fastening groove 411 and the gripper 424a cooperate with each other as follows: When the lifting mechanism 42 needs to grab the pressure block 41, firstly, the push-pull cylinder 423 pushes the lifting mechanism 42 forward to directly above the pressure block 41. Then, the lifting cylinder 421 drives the clamping cylinder 424 to move downwards simultaneously to the fastening groove 411 position at the top of the pressure block 41. At this time, the clamping cylinder 424 is in a clamping state and begins to slowly move, driving the gripper 424a to open to the left and right sides simultaneously. When the clamping cylinder 424 moves to the fully opened state, the gripper 424a is just connected with the fastening groove 411. Then, the lifting cylinder 421 begins to move upwards, driving the gripper 424a to move upwards simultaneously. However, due to the blocking effect of the fastening groove 411, the pressure block 41 is moved upwards. At the same time, when the pressure block transfer is completed, the push-pull cylinder 423 drives the lifting mechanism 42 back to the initial position to avoid interfering with subsequent battery loading.

[0066] Similarly, when it is necessary to place the pressure block 41, firstly, the pushing mechanism 3 pushes the locking mechanism 10 to one side, at which point a space for placing the pressure block 41 is created inside the rectangular frame. The push-pull cylinder 423 pushes the lifting mechanism 42 and the pressure block 41 forward to the top of this space. Then, the lifting cylinder 421 moves downward, causing the gripper 424a and the pressure block 41 to move downward synchronously until the pressure block 41 is placed inside the rectangular frame. At this time, the clamping cylinder 424 retracts inward, causing the gripper 44 to move inward synchronously, thus freeing it from the constraint of the fastening groove 411. Next, the lifting cylinder 421 and the push-pull cylinder 423 drive the lifting mechanism 42 to reset, completing the placement of the pressure block 41. By placing the pressure block 41 inside the rectangular frame through the pressure block lifting mechanism 40, it is ensured that the partition 12 no longer moves on the guide rod 13. At this time, the battery is completely fixed in the cavity 16 and compressed to its minimum. The battery will not shake inside the cavity 16 and remains in a locked state.

[0067] The bottom of the pressure block 41 is provided with a U-shaped groove 412, the position and size of which are adapted to the push column 34 of the push mechanism 30. The purpose is that after the battery is loaded, the push cylinder 31 pushes the connecting plate 12 forward to compress the partition 14 to one side and lock the locking mechanism 10. The lifting mechanism 42 then places the pressure block 41 in the extra space after the locking mechanism 10 is compressed. The push column 34 can pass through the pressure block 41. The two do not interfere with each other and complete the locking state of the locking mechanism 10.

[0068] Example 2

[0069] according to Figure 9-11 As shown, this embodiment provides a battery moving lock clamp system, which applies the battery moving lock clamp device of Embodiment 1 to the production line 70. The production line 70 is provided with multiple locking mechanisms 10, and each locking mechanism 10 is provided with multiple pressure blocks 41. The locking mechanism 10 can be moved quickly through the production line 70.

[0070] In order to accommodate the unlocking mechanism 20, the pushing mechanism 30, and the pressing block lifting mechanism 40 in the battery moving lock clamp device, this embodiment provides mounting brackets 80 on both sides of the assembly line body 70. The mounting brackets 80 are respectively provided with mounting platforms 81 on both sides of the assembly line body 70. The pushing mechanism 30 is mounted on the mounting platform 81, the pressing block lifting mechanism 40 is mounted on the mounting bracket 80 on one side of the first end plate 11, and the unlocking mechanism 20 is mounted on the crossbeam (not shown in the figure) between the two mounting platforms 81. The crossbeam is provided with a cylinder that can vertically move the unlocking mechanism 20.

[0071] The assembly line 70 includes an assembly frame 71, on which a drive motor 72 is mounted. Multiple photoelectric sensors 75 are arranged on both sides of the assembly frame 71. The spacing between the photoelectric sensors 75 ensures a safe distance between locking mechanisms 10 and the next locking mechanism 10. The locking mechanism 10 is placed on the assembly frame 71 and moves along the assembly frame 71 via the drive motor 72 to transport batteries. A stop cylinder 74 is fixed to a cross brace 73. Multiple locking mechanisms 10 move stably forward along the assembly frame 71. The drive motor 72 provides the power for movement along the assembly frame 71. The stop cylinder 74 transmits signals through the photoelectric sensors 75 to stop or release the locking mechanisms 10, ensuring orderly battery loading and unloading.

[0072] In this embodiment, a lifting mechanism 90 is also provided below the assembly line body 70. The lifting mechanism 90 is also set on the crossbeam (not shown in the figure) between the two mounting platforms 81. The lifting mechanism 90 is used to lift the locking mechanism 10 so that it leaves the assembly line body 70 and is at the same height as the pushing mechanism 30.

[0073] The lifting mechanism 90 includes a fixed plate 92, which is fixed to a crossbeam between two mounting platforms 81. The fixed plate 92 is used to fix a lifting cylinder 91. The telescopic end of the lifting cylinder 91 is connected to a lifting plate 93, which is positioned above the fixed plate 92. Guide posts 94 are provided at the four corners of the top of the fixed plate 92. The guide posts 94 pass through the lifting plate 93 and contact the four corners of the locking mechanism 10. Bearings (not shown in the figure) are provided at the four corners of the lifting plate 93, and the guide posts 94 pass through the lifting plate 93 via the bearings. A top post 95 is provided at the top of the lifting plate 93. The lifting cylinder 91 lifts the lifting plate 93, allowing it to move vertically within the guide posts 94. The lifting plate 93 contacts the locking mechanism 10 via the top post 95, thereby lifting the locking mechanism 10 away from the assembly line body 70 and placing it at the same height as the pushing mechanism 30, ensuring the stability of the lifting and locking mechanism 10.

[0074] The working principle of the battery movable locking system in this embodiment is as follows:

[0075] (1) Multiple locking mechanisms 10 are placed on the assembly line body 70. When the current locking mechanism 10 moves to the battery loading position, the photoelectric sensor 75 sends a signal to the stop cylinder 74, and the stop cylinder 74 blocks the current locking mechanism 10 from moving forward. Similarly, when the next locking mechanism 10 moves to a safe distance, the corresponding photoelectric sensor 75 sends a signal to the stop cylinder 74 and prevents it from moving forward.

[0076] (2) Next, the lifting cylinder 91 moves vertically upward to lift the lifting plate 93, so that the lifting plate 93 moves vertically at the limit of the guide post 94. The lifting plate 93 contacts the locking mechanism 10 through the top post 95, thereby lifting the locking mechanism 10 away from the assembly line body 70 and at the same height as the pushing mechanism 30.

[0077] (3) Next, the unlocking mechanism 20 moves downward by the cylinder so that the unlocking mechanism 20 and the locking mechanism 10 are at the same height. At this time, the pushing mechanism 30 starts to move. The pushing cylinder 31 pushes the pushing column 34 through the U-shaped groove 412 of the pressure block 41 and the through hole 111 of the first end plate 11 to contact the connecting plate 12. At the same time, the blocking cylinder 32 carries the blocking block 33 to the other end of the locking mechanism 10. The locking mechanism 10 is fixed by the pushing mechanism 30.

[0078] (4) Next, the pressing block 41 in the rectangular frame of the locking mechanism 10 is removed by the lifting mechanism 42. At this time, the first cylinder 241 of the unlocking mechanism 20 provides thrust to move the unlocking mechanism 20 from both sides of the locking mechanism 10 toward the locking mechanism 10, so that the unlocking head 221 and the fixing hole 141 are engaged one by one. Then the first cylinder 241 moves the connecting block 242 toward the first end plate 11. The connecting block 242 moves the unlocking component 22 on the slide rail 26. The unlocking head 221 moves the partition 14 toward the first end plate 11, so that the cavity 16 formed between the partitions 14 reaches the maximum space, and the unlocking action of the locking mechanism 10 is completed.

[0079] (5) Next, the battery is placed in the cavity 16 of the locking mechanism 10 by the robotic arm. After the battery is placed, the second cylinder 27 of the unlocking mechanism 20 provides power and moves away from the locking mechanism 10, so that the unlocking head 221 is pulled out of the fixing hole 141. The first cylinder 241 moves with the connecting block 242 in the opposite direction to the first end plate 11, so that the unlocking component 22 moves in the opposite direction to the first end plate 11 on the slide rail 26, thereby realizing the reset of the unlocking component 22. At this time, the pushing mechanism 30 then operates. The pushing column 34 contacts the connecting plate 12 and continues to apply pushing force through the pushing cylinder 31, so that the partition 14 moves inward along the guide rod 13 until the cavity 16 inside the partition 14 is compressed to the minimum space and moved to one end, leaving the space required for the pressure block 41, and locking the battery in the cavity 16.

[0080] (6) Next, the pressing block lifting mechanism 40 starts to operate, and the pressing block 41 is placed in the space reserved by the locking mechanism 10 through the lifting mechanism 42, keeping the locking mechanism 10 locked. Then the lifting mechanism 42 returns to the original point so as not to block the movement of the locking mechanism 10.

[0081] (7) Next, the unlocking mechanism 20 will move upward through the cylinder on the cross frame to complete the reset of the unlocking mechanism 20; at this time, the push mechanism 30 will start to reset, and the push column 34 will be pulled out from the first end plate 11 and the pressure block 41 in sequence, while the blocking block 33 will no longer be in contact with the locking mechanism 10.

[0082] (8) Next, the locking mechanism 10 is driven by the lifting cylinder 91 and moves downward synchronously with the lifting mechanism 90, so that the locking mechanism 10 is placed back on the production line body 70, and the stopping cylinder 74 moves synchronously to release the current and the next locking mechanism 10, thus completing the unlocking of the locking mechanism 10 and the battery loading locking, and the locking mechanism 10 moves quickly through the production line body 70.
