Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a tray mechanism, a battery module processing method, and a battery. Background Technology

[0002] In existing battery production lines, trays are among the components with the highest consumption. Due to the variety of power battery products, mixed production often occurs on the same production line. Summary of the Invention

[0003] The main objective of this invention is to provide a tray mechanism, a battery module processing method, and a battery, aiming to solve the technical problems of high cost, complex structure, single function, and low efficiency of existing solutions.

[0004] To achieve the above objectives, the present invention provides a tray mechanism, a battery module processing method, and a battery:

[0005] The tray mechanism consists of a tray base plate 1, a bottom insulating plate 2, a clamping mechanism 3, a synchronous linkage mechanism 4, a floating reference mechanism 5, a limiting block 6, and a spring-loaded block mechanism 7. The bottom insulating plate 2, the clamping mechanism 3, the floating reference mechanism 5, the limiting block 6, and the spring-loaded block mechanism 7 are installed on the tray base plate 1. Due to limited installation space, a square recess is carved into the tray base plate 1. The synchronous linkage mechanism 4 is installed in the square recess of the tray base plate 1, thus spatially offsetting the synchronous linkage mechanism 4 from the bottom insulating plate 2 and the floating reference mechanism 5, making the structure more compact. A battery module is called a single-row module if the cells are packaged in one row, and a double-row module if there are two rows. Battery modules include various types, such as single-row modules and double-row modules.

[0006] Optionally, when two single-row modules 8 need to be placed, the two single-row modules 8 are placed on the bottom insulating plate 2. One end of the single-row module 8 is positioned against the limiting block 6 in the length direction, while the pop-up block mechanism 7 locks the other end of the single-row module 8 to prevent it from shaking. The single-row module 8 is positioned against the floating reference mechanism 5 on one side in the width direction, and the clamping mechanism 3 clamps the other side of the single-row module 8 to prevent it from shaking.

[0007] Optionally, the floating reference mechanism 5 is installed in the middle of the width direction of the tray bottom plate 1. During operation, the floating reference mechanism 5 is higher than the bottom insulating plate 2 and sandwiched between the two single-row modules 8, serving as a reference in the width direction of the two single-row modules 8.

[0008] Optionally, when a double-row module 9 needs to be placed, the double-row module 9 is placed on the bottom insulating plate 2, and one end of the double-row module 9 is positioned against the limiting block 6 in the length direction, while the pop-up block mechanism 7 locks the other end of the double-row module 9 to prevent it from shaking.

[0009] Optionally, when the double-row module 9 is placed on the bottom insulating plate 2, it will press down the floating reference mechanism 5 as a whole. Therefore, the floating reference mechanism 5 cannot be used as a reference in the width direction of the double-row module 9. For this reason, the present invention designs a synchronous linkage mechanism 4. The synchronous linkage mechanism 4 can make the two clamping mechanisms 3 clamping both sides of the double-row module 9 open or close synchronously. This makes the width direction of the double-row module 9 clamped in the middle of the tray. That is, the positioning of the width direction of the double-row module 9 is achieved by the synchronous linkage mechanism 4.

[0010] Optionally, the clamping mechanism 3 consists of a linear guide rail 3-1, a mounting plate 3-2, a clamping block 3-3, a spring seat 3-4, a spring 3-5, and a spring limit seat 3-6. The linear guide rail 3-1 is mounted on the tray base plate 1, the mounting plate 3-2 is mounted on the linear guide rail 3-1, and the clamping block 3-3 is mounted on the mounting plate 3-2. Because of the use of the linear guide rail 3-1, the mounting plate 3-2 can slide back and forth in the width direction of the module. The spring seat 3-4 is mounted on the tray base plate 1. One end of the spring 3-5 rests against the spring seat 3-4, and the other end pushes the mounting plate 3-2 to move towards the module. The spring limit seat 3-6 is also mounted on the tray base plate 1 and is used to limit the range of movement of the mounting plate 3-2 towards the module. When the mounting plate 3-2 moves towards the module, the upper limit of movement in this direction is when the mounting plate 3-2 touches the spring limit seat 3-6. When the mounting plate 3-2 moves in the opposite direction, the upper limit of movement in this direction is when the spring is compressed and tightened. Because spring 3-5 is pre-compressed, spring 3-5 always has spring force to keep clamping block 3-3 pressing the module.

[0011] The mounting threaded holes on the mounting plate 3-2 are a row of equidistant threaded holes. Therefore, the position of the clamping block 3-3 can be adjusted by changing the position of the threaded holes, thus achieving compatibility with modules of different widths. Similarly, the mounting threaded holes on the limiting block 6 and the spring-loaded block mechanism 7 on the tray base plate 1 are a row of equidistant threaded holes. The limiting block 6 and the spring-loaded block mechanism 7 can be adjusted by changing the position of the threaded holes, thus achieving compatibility with modules of different lengths. In summary, the tray of the present invention can achieve compatibility with single and double row modules of different length, width, and height specifications.

[0012] Optionally, the synchronous linkage mechanism 4 consists of a bearing pin 4-1, a bearing 4-2, a swing arm 4-3, and a connecting rod 4-4. The bearing pin 4-1 is installed at the center of the width direction of the pallet bottom plate 1. The bearing 4-2 is installed on the bearing pin 4-1. The swing arm 4-3 is installed on the bearing 4-2. The swing arm 4-3 can rotate around the bearing pin 4-1. The two ends of the swing arm 4-3 are connected to the connecting rod 4-4. The connecting rod 4-4 is then connected to the mounting plates 3-2 at both ends. Through the synchronous linkage mechanism 4, the mounting plates 3-2 at both ends can move synchronously, moving towards or in opposite directions at the same time.

[0013] Optionally, when in the clamped state, the angle between the swing arm 4-3 and the mounting plate 3-2 is 40.6°.

[0014] Optionally, when in the unlocked state, the angle between the swing arm 4-3 and the mounting plate 3-2 is 12.4°.

[0015] Optionally, the floating reference mechanism 5 consists of guide seats 5-1, spring push rods 5-2, compression springs 5-3, cylindrical pins 5-4, and a floating reference plate 5-5. Two guide seats 5-1 are mounted on the tray base plate 1, and the tray base plate 1 is equipped with corresponding countersunk holes to save space. The spring push rod 5-2 is installed inside the guide seat 5-1 and can slide up and down within it. The compression spring 5-3 is inside the spring push rod 5-2, with its lower end against the tray base plate 1 and its upper end pushing upwards against the spring push rod 5-2. The floating reference plate 5-5 is connected to the two spring push rods 5-2 via two cylindrical pins 5-4. The compression spring 5-3 is pre-compressed. When the double-row module 9 does not press down on the floating reference plate 5-5, the floating reference plate 5-5 remains in the upper position; when the double-row module 9 presses down on the floating reference plate 5-5, the floating reference plate 5-5 is in the lower position. When using a single-row module, its relatively narrow width allows for effective limiting. When using a double-row module, its wider width allows it to press down floating reference mechanisms smaller than its own width. Floating reference mechanisms 5 with a width greater than the double-row module's width between each other still function as limiters. This means that both single-row and double-row battery modules can be confined between two or more specific floating reference mechanisms, ensuring stability during transport and preventing damage or collisions. This guarantees the stability and safety of both single and double-row battery modules during transport.

[0016] Optionally, the pop-up block mechanism 7 consists of a mounting base 7-1, a pop-up block 7-2, and a spring 7-3. The mounting base 7-1 is mounted on the tray base plate 1, and the pop-up block 7-2 is mounted in the inner cavity of the mounting base 7-1 and can slide up and down in the inner cavity of the mounting base 7-1. The lower end of the spring 7-3 is attached to the tray base plate 1, and the upper end pushes the pop-up block 7-2 upward. The spring 7-3 is pre-compressed, and when it is not under pressure, the pop-up block 7-2 is in the upper position. Because when the module is placed on the tray, whether it is placed manually or by a robot, the position will not be very precise. Although the module and the limiting block 6 are finally in close contact, there is a gap of a few millimeters when it is initially placed. That is, the module is offset by a few millimeters in the direction of the pop-up block 7-2. This will cause the module to press the pop-up block mechanism 7 down until it is flush with the bottom insulating plate 2. Then the module moves towards the limiting block 6 and aligns with it. After the module is separated from the pop-up block mechanism 7, the pop-up block mechanism 7 uses spring force to pop up and lock the end face of the module so that the module cannot shake in the length direction.

[0017] Optionally, an unlocking mechanism 10 is also provided. The pallet carries the module and travels back and forth between various workstations on the production line. When the pallet reaches the workstation where loading or unloading requires unlocking, the unlocking mechanism 10 unlocks the clamping mechanism 3, which is in a clamping state. Driven by a cylinder or motor, the unlocking mechanism 10 pulls the mounting plate 3-2 outward, and the clamping mechanism 3, which was originally in a clamping state, releases the pallet, thus achieving unlocking.

[0018] Optionally, the cylinder on the unlocking mechanism 10 drives the unlocking mechanism pull plate 10-1 to pull the clamping mechanism 3 on one side of the tray backward, and the synchronous linkage mechanism 4 realizes the synchronous action of the clamping mechanism 3 on the other side of the tray to achieve unlocking.

[0019] Optionally, when a battery module is placed on the tray, the clamping mechanism 3 disengages from the battery module so that the battery module can be removed.

[0020] When no battery module is placed on the tray, the clamping block 3-3 of the clamping mechanism 3 moves backward to create a space gap in the width direction of the battery module, so that the battery module can be placed on the tray.

[0021] Optionally, after the battery module is placed or removed, the cylinder on the unlocking mechanism 10 drives the unlocking mechanism pull plate 10-1 to move towards the battery module, releasing the mounting plate 3-2 on the clamping mechanism 3. Under the action of the spring force, the clamping mechanism 3 moves forward to clamp the battery module, and the clamping force is equal to the spring pressure, thereby achieving the clamping of the tray. Specifically, the tray carrying the battery module travels back and forth between various workstations on the assembly line. When the tray reaches the workstation where unlocking is required for loading and unloading, the unlocking mechanism 10 is installed on the assembly line frame of this workstation. The cylinder on the unlocking mechanism 10 drives the unlocking mechanism pull plate 10-1 to pull the mounting plates 3-2 on the three sets of clamping mechanisms 3 on one side of the tray backward against the spring force. The synchronous linkage mechanism 4 realizes the synchronous action of the three sets of clamping mechanisms 3 on the other side of the tray. In this way, all six sets of clamping mechanisms on the tray move backward to unlock the tray. If there is a battery module on the tray, the six clamping mechanisms disengage from the battery module, allowing it to be removed. If there is no battery module on the tray, the six clamping blocks move backward to create space in the width direction of the battery module, making it easier to place the battery module on the tray. After the battery module is placed or removed, the cylinder on the unlocking mechanism 10 drives the unlocking mechanism pull plate 10-1 to move towards the battery module, releasing the mounting plate 3-2 on the three clamping mechanisms 3. Under the action of the spring force, the six clamping mechanisms move forward to clamp the battery module, and the clamping force is equal to the spring pressure, thus clamping the tray. In summary, because the synchronous linkage mechanism drives the clamping mechanisms on both sides to move synchronously, only one unlocking mechanism is needed on the production line to pull the clamping mechanism, which can achieve synchronous action of the clamping mechanisms on both sides to unlock the tray, thus saving costs.

[0022] A battery module processing method is provided, characterized by comprising:

[0023] Step S10: Receive the battery module placement instruction and determine the type of the battery module to be placed;

[0024] Step S20: If the type of battery module to be placed is a single-row module, then place the two single-row modules 8 on the bottom insulating plate 2. The single-row module 8 is positioned against the limiting block 6 at one end in the length direction, while the pop-up block mechanism 7 holds the other end of the single-row module 8 to prevent it from shaking. The single-row module 8 is positioned against the floating reference mechanism 5 on one side in the width direction, and the clamping mechanism 3 clamps the other side of the single-row module 8 to prevent it from shaking.

[0025] When a double-row module 9 needs to be placed, the double-row module 9 is placed on the bottom insulating plate 2. One end of the double-row module 9 is positioned against the limiting block 6 in the length direction, while the pop-up block mechanism 7 locks the other end of the double-row module 9 to prevent it from shaking.

[0026] Optionally, step S20 includes:

[0027] Step S201: When it is a single-row module, the floating reference mechanism 5 is higher than the bottom insulating plate 2 and sandwiched between the two single-row modules 8, serving as a reference in the width direction of the two single-row modules 8.

[0028] Optionally, step S20 includes:

[0029] In step S202, when it is a double-row module, the double-row module 9 is placed on the bottom insulating plate 2 and the floating reference mechanism 5 is pressed down as a whole. The two clamping mechanisms 3 clamping both sides of the double-row module 9 are simultaneously released or clamped through the synchronous linkage mechanism 4, so that the width direction of the double-row module 9 is clamped in the middle of the tray. The positioning of the width direction of the double-row module 9 is achieved through the synchronous linkage mechanism 4.

[0030] A battery is provided, comprising: the battery being a finished battery or a semi-finished battery obtained after being processed by any of the above-mentioned tray mechanisms during the manufacturing process; or, the battery being a finished battery or a semi-finished battery obtained after being processed by any of the above-mentioned battery module processing methods.

[0031] The beneficial effects are as follows: The pallet achieves compatibility between long and short modules by adjusting the installation positions of the limiting blocks and spring-loaded blocks, and between wide and narrow modules by adjusting the installation positions of the clamping blocks, thus enabling compatibility with modules of different lengths and widths. The pallet's floating reference mechanism can act as a positioning reference surface for single-row modules when two single-row modules are placed. When a double-row module is placed, the entire assembly is pressed down, and the synchronous linkage mechanism drives the clamping mechanisms on both sides to move synchronously, achieving centering and positioning of the double-row module on the pallet, thus enabling compatibility between single and double-row modules. Similarly, because the synchronous linkage mechanism drives the clamping mechanisms on both sides to move synchronously, only one unlocking mechanism is needed on the production line to pull the clamping mechanisms, achieving synchronous movement of the clamping mechanisms on both sides to unlock the pallet, thereby saving costs.

For those skilled in the art, the specific meaning of the above terms in the present invention can be understood according to the specific circumstances.

[0045] The present invention will be further described below with reference to the accompanying drawings:

[0046] Reference Figure 1-12In one embodiment of the present invention, the pallet is composed of a pallet base plate 1, a bottom insulating plate 2, a clamping mechanism 3, a synchronous linkage mechanism 4, a floating reference mechanism 5, a limiting block 6, and a spring-loaded block mechanism 7. The bottom insulating plate 2, the clamping mechanism 3, the floating reference mechanism 5, the limiting block 6, and the spring-loaded block mechanism 7 are installed on the pallet base plate 1. Due to limited installation space, a square recess is dug in the pallet base plate 1. The synchronous linkage mechanism 4 is installed in the square recess of the pallet base plate 1, so that the synchronous linkage mechanism 4 is spatially offset from the bottom insulating plate 2 and the floating reference mechanism 5, making the structure more compact.

[0047] Reference Figure 1-12 In one embodiment, when two single-row modules 8 need to be placed, the two single-row modules 8 are placed on the bottom insulating plate 2. One end of the single-row module 8 is positioned against the limiting block 6 in the length direction, while the pop-up block mechanism 7 locks the other end of the single-row module 8 to prevent it from shaking. The single-row module 8 is positioned against the floating reference mechanism 5 on one side in the width direction, and the clamping mechanism 3 clamps the other side of the single-row module 8 to prevent it from shaking.

[0048] Reference Figure 1-12 In one embodiment, the floating reference mechanism 5 is installed in the middle of the width direction of the tray bottom plate 1. When working, the floating reference mechanism 5 is higher than the bottom insulating plate 2 and sandwiched between the two single-row modules 8, serving as a reference in the width direction of the two single-row modules 8.

[0049] Reference Figure 1-12 In one embodiment, when a double-row module 9 needs to be placed, the double-row module 9 is placed on the bottom insulating plate 2, and one end of the double-row module 9 is positioned against the limiting block 6 in the length direction, while the pop-up block mechanism 7 locks the other end of the double-row module 9 to prevent it from shaking.

[0050] Reference Figure 1-12 In one embodiment, when the double-row module 9 is placed on the bottom insulating plate 2, it will press down the floating reference mechanism 5 as a whole. Therefore, the floating reference mechanism 5 cannot be used as a reference in the width direction of the double-row module 9. For this reason, the present invention designs a synchronous linkage mechanism 4. The synchronous linkage mechanism 4 can make the two clamping mechanisms 3 clamping both sides of the double-row module 9 open or close synchronously. This makes the width direction of the double-row module 9 clamped in the middle of the tray. That is, the positioning of the width direction of the double-row module 9 is achieved by the synchronous linkage mechanism 4.

[0051] Reference Figure 1-12In one embodiment, the clamping mechanism 3 consists of a linear guide rail 3-1, a mounting plate 3-2, a clamping block 3-3, a spring seat 3-4, a spring 3-5, and a spring limiting seat 3-6. The linear guide rail 3-1 is mounted on the tray base plate 1, the mounting plate 3-2 is mounted on the linear guide rail 3-1, and the clamping block 3-3 is mounted on the mounting plate 3-2. Because of the use of the linear guide rail 3-1, the mounting plate 3-2 can slide back and forth in the width direction of the module. The spring seat 3-4 is mounted on the tray base plate 1, one end of the spring 3-5 is against the spring seat 3-4, and the other end pushes the mounting plate 3-2 to move in the direction of the module. The spring limiting seat 3-6 is also mounted on the tray base plate 1 to limit the range of movement of the mounting plate 3-2 in the direction of the module. When the mounting plate 3-2 moves in the direction of the module, the upper limit of the movement in this direction is when the mounting plate 3-2 touches the spring limiting seat 3-6. When the mounting plate 3-2 moves in the opposite direction, the upper limit of the movement in this direction is when the spring is compressed and tightened. Because spring 3-5 is pre-compressed, spring 3-5 always has spring force to keep clamping block 3-3 pressing the module.

[0052] The mounting threaded holes on the mounting plate 3-2 are a row of equidistant threaded holes. Therefore, the position of the clamping block 3-3 can be adjusted by changing the position of the threaded holes, thus achieving compatibility with modules of different widths. Similarly, the mounting threaded holes on the limiting block 6 and the spring-loaded block mechanism 7 on the tray base plate 1 are a row of equidistant threaded holes. The limiting block 6 and the spring-loaded block mechanism 7 can be adjusted by changing the position of the threaded holes, thus achieving compatibility with modules of different lengths. In summary, the tray of the present invention can achieve compatibility with single and double row modules of different length, width, and height specifications.

[0053] Reference Figure 1-12 In one embodiment, the synchronous linkage mechanism 4 consists of a bearing pin 4-1, a bearing 4-2, a swing arm 4-3, and a connecting rod 4-4. The bearing pin 4-1 is installed at the center of the width direction of the tray bottom plate 1. The bearing 4-2 is installed on the bearing pin 4-1. The swing arm 4-3 is installed on the bearing 4-2. The swing arm 4-3 can rotate around the bearing pin 4-1. The two ends of the swing arm 4-3 are connected to the connecting rod 4-4. The connecting rod 4-4 is then connected to the mounting plates 3-2 at both ends. Through the synchronous linkage mechanism 4, the mounting plates 3-2 at both ends can move synchronously, moving towards or in opposite directions at the same time.

[0054] Reference Figure 1-12 In one embodiment, when in the clamped state, the angle between the swing arm 4-3 and the mounting plate 3-2 is 40.6°, or (12.4°, 90°).

[0055] Reference Figure 1-12 In one embodiment, when in the unlocked state, the angle between the swing arm 4-3 and the mounting plate 3-2 is 12.4°, or (0-12.4°).

[0056] Reference Figure 1-12 In one embodiment, the floating reference mechanism 5 consists of a guide seat 5-1, a spring push rod 5-2, a compression spring 5-3, a cylindrical pin 5-4, and a floating reference plate 5-5. Two guide seats 5-1 are mounted on the tray base plate 1, and the tray base plate 1 is equipped with corresponding countersunk holes to save space. The spring push rod 5-2 is installed inside the guide seat 5-1 and can slide up and down within it. The compression spring 5-3 is located inside the spring push rod 5-2, with its lower end against the tray base plate 1 and its upper end pushing upwards against the spring push rod 5-2. The floating reference plate 5-5 is connected to the two spring push rods 5-2 via two cylindrical pins 5-4. The compression spring 5-3 is pre-compressed. When the double-row module 9 does not press down on the floating reference plate 5-5, the floating reference plate 5-5 remains in the upper position; when the double-row module 9 presses down on the floating reference plate 5-5, the floating reference plate 5-5 is in the lower position.

[0057] Reference Figure 1-12 In one embodiment, the pop-up block mechanism 7 consists of a mounting base 7-1, a pop-up block 7-2, and a spring 7-3. The mounting base 7-1 is mounted on the tray base plate 1, and the pop-up block 7-2 is mounted in the inner cavity of the mounting base 7-1 and can slide up and down in the inner cavity of the mounting base 7-1. The lower end of the spring 7-3 is attached to the tray base plate 1, and the upper end pushes the pop-up block 7-2 upward. The spring 7-3 is pre-compressed, and when it is not under pressure, the pop-up block 7-2 is in the upper position. Because when the module is placed on the tray, whether it is placed manually or by a robot, the position will not be very precise. Although the module and the limiting block 6 are finally in close contact, there is a gap of a few millimeters when it is initially placed. That is, the module is offset by a few millimeters in the direction of the pop-up block 7-2. This will cause the module to press the pop-up block mechanism 7 down until it is flush with the bottom insulating plate 2. Then the module moves towards the limiting block 6 and aligns with it. After the module is separated from the pop-up block mechanism 7, the pop-up block mechanism 7 uses spring force to pop up and lock the end face of the module so that the module cannot shake in the length direction.

[0058] Reference Figure 1-12 In one embodiment, an unlocking mechanism 10 is also provided. The pallet carries the module and travels back and forth between various workstations on the production line. When the pallet reaches the workstation where loading or unloading requires unlocking, the unlocking mechanism 10 unlocks the clamping mechanism 3 which is in a clamping state.

[0059] Reference Figure 1-12 In one embodiment, the cylinder on the unlocking mechanism 10 drives the unlocking mechanism pull plate 10-1 to pull the clamping mechanism 3 on one side of the tray to move backward, and the synchronous linkage mechanism 4 realizes the synchronous action of the clamping mechanism 3 on the other side of the tray to achieve unlocking.

[0060] Reference Figure 1-12 In one embodiment, when a module is placed on the tray, the clamping mechanism 3 disengages from the module so that the module can be removed.

[0061] When no module is placed on the tray, the clamping block 3-3 of the clamping mechanism 3 moves backward to create a space gap in the width direction of the module, so that the module can be placed on the tray.

[0062] Reference Figure 1-12 In one embodiment, after the module is placed or removed, the cylinder on the unlocking mechanism 10 drives the unlocking mechanism pull plate 10-1 to move towards the module, releasing the mounting plate 3-2 on the clamping mechanism 3. Under the action of the spring force, the clamping mechanism 3 moves forward to clamp the module, and the clamping force is equal to the spring pressure, thereby achieving the clamping of the tray. Specifically, the tray carries the module and travels back and forth between various workstations on the assembly line. When the tray reaches the workstation where unlocking is required for loading and unloading, the unlocking mechanism 10 is installed on the assembly line frame of this workstation. The cylinder on the unlocking mechanism 10 drives the unlocking mechanism pull plate 10-1 to pull the mounting plate 3-2 on the three sets of clamping mechanisms 3 on one side of the tray to move backward against the spring force. The synchronous linkage mechanism 4 realizes the synchronous action of the three sets of clamping mechanisms 3 on the other side of the tray. In this way, all six sets of clamping mechanisms on the tray move backward to unlock the tray. If there is a module on the pallet, the six clamping mechanisms disengage from the module, allowing it to be removed. If there is no module on the pallet, the six clamping blocks move backward to create space in the width direction of the module, making it easier to place the module on the pallet. After the module is placed or removed, the cylinder on the unlocking mechanism 10 drives the unlocking mechanism pull plate 10-1 to move towards the module, releasing the mounting plate 3-2 on the three clamping mechanisms 3. Under the action of the spring force, the six clamping mechanisms move forward to clamp the module, and the clamping force is equal to the spring pressure, thus clamping the pallet. In summary, because the synchronous linkage mechanism drives the clamping mechanisms on both sides to move synchronously, only one unlocking mechanism is needed on the production line to pull the clamping mechanism, which can achieve synchronous movement of the clamping mechanisms on both sides to unlock the pallet, thus saving costs.

[0063] A battery module processing method is provided, characterized by comprising:

[0064] Step S10: Receive module placement instruction and determine the type of module to be placed;

[0065] Step S20: If the type of module to be placed is a single-row module, then place the two single-row modules 8 on the bottom insulating plate 2. The single-row module 8 is positioned against the limiting block 6 at one end in the length direction, while the pop-up block mechanism 7 locks the other end of the single-row module 8 to prevent it from shaking. The single-row module 8 is positioned against the floating reference mechanism 5 on one side in the width direction, and the clamping mechanism 3 clamps the other side of the single-row module 8 to prevent it from shaking.

[0066] When a double-row module 9 needs to be placed, the double-row module 9 is placed on the bottom insulating plate 2. One end of the double-row module 9 is positioned against the limiting block 6 in the length direction, while the pop-up block mechanism 7 locks the other end of the double-row module 9 to prevent it from shaking.

[0067] In one embodiment, step S20 includes:

[0068] Step S201: When it is a single-row module, the floating reference mechanism 5 is higher than the bottom insulating plate 2 and sandwiched between the two single-row modules 8, serving as a reference in the width direction of the two single-row modules 8.

[0069] In one embodiment, step S20 includes:

[0070] In step S202, when it is a double-row module, the double-row module 9 is placed on the bottom insulating plate 2 and the floating reference mechanism 5 is pressed down as a whole. The two clamping mechanisms 3 clamping both sides of the double-row module 9 are simultaneously released or clamped through the synchronous linkage mechanism 4, so that the width direction of the double-row module 9 is clamped in the middle of the tray. The positioning of the width direction of the double-row module 9 is achieved through the synchronous linkage mechanism 4.

[0071] A battery is provided, comprising: the battery being a finished battery or a semi-finished battery obtained after being processed by any of the above-mentioned tray mechanisms during the manufacturing process; or, the battery being a finished battery or a semi-finished battery obtained after being processed by any of the above-mentioned battery module processing methods.

[0072] Compatibility between long and short modules is achieved by adjusting the installation positions of the limiting block and the spring-loaded block mechanism, and compatibility between wide and narrow modules is achieved by adjusting the installation positions of the clamping block, thus enabling compatibility with modules of different lengths and widths. In this invention, the floating reference mechanism of the tray can act as a positioning reference surface for two single-row modules. When a double-row module is placed, the entire assembly is pressed down, and the synchronous linkage mechanism drives the clamping mechanisms on both sides to move synchronously, achieving center positioning of the double-row module on the tray, thus enabling compatibility with both single and double-row modules. Similarly, because the synchronous linkage mechanism drives the clamping mechanisms on both sides to move synchronously, only one unlocking mechanism is needed on the production line to pull the clamping mechanisms, achieving synchronous movement of the clamping mechanisms on both sides to unlock the tray, thereby saving costs. This invention achieves multi-module compatibility while reducing structural complexity, simplifying the battery manufacturing process, and improving production efficiency.
