[0033] Please see Figure 1 This application provides a packaging device, including a steel strapping device 1 and a steel strap unslipping device 2. The steel strapping device 1 includes a loading mechanism 10 and a steel strapping mechanism 20. The loading mechanism 10 is used to load a battery module B. The steel strapping mechanism 20 is arranged above the loading mechanism 10 and is used to pick up steel strap A and slip the picked-up steel strap A over the battery module B from above and downwards. The steel strap unslipping device 2 is arranged below the loading mechanism 10 and is used to pick up steel strap A and slip the picked-up steel strap A over the battery module B from below and upwards.

[0034] The steel strip feeding mechanism 20 includes a pickup assembly 21 and at least two steel strip pushing assemblies 23 arranged on opposite sides of the pickup assembly 21. Each steel strip pushing assembly 23 has a lifting drive 231 and a steel strip pushing block 234 mounted on the drive end of the lifting drive 231. It should be noted that the lifting drive 231 can be a linear drive module such as an electric cylinder or a linear motor, as long as it can drive the steel strip pushing block 234 to push the steel strip A downward, and there is no limitation here.

[0035] In this way, the steel strip A is first picked up by the picking component 21, and then each lifting drive component 231 drives each pushing steel strip block 234 to move downward, so that each pushing steel strip block 234 simultaneously pushes the steel strip A on the picking component 21 downward until the steel strip A is placed on the outside of the battery module B below. This realizes automatic placement of the steel strip A, improves the degree of automation, simplifies manual operation, reduces safety risks, and improves the packaging efficiency of the battery module B.

[0036] Please see Figures 2 to 6 In the embodiments of this application, each steel strip pusher assembly 23 further includes a first drive member 232, an adapter 233, and a support block 235. The first drive member 232 is installed on the drive end of the lifting drive member 231, enabling the lifting drive member 231 to drive the first drive member 232 to rise or fall. The adapter 233 is installed on the drive end of the first drive member 232, enabling the first drive member 232 to drive the adapter 233 to move closer to or away from the steel strip A on the pickup assembly 21. The aforementioned steel strip pusher block 234 and support block 235 are both disposed on the adapter 233, enabling the adapter 233 to drive the steel strip pusher block 234 and support block 235 to move closer to or away from the steel strip A on the pickup assembly 21 together. The support block 235 is located below the steel strip pusher block 234, and a receiving space a1 for the steel strip A to enter or exit is formed between the steel strip pusher block 234 and the support block 235. Optionally, the first drive component 232 may be a cylinder.

[0037] Thus, in the actual production process, firstly, the pickup assembly 21 picks up the steel strip A and moves it to the top of the battery module B on the loading mechanism 10; at this time, the steel strip A on the pickup assembly 21 is aligned with the battery module B below it, ensuring that the steel strip A can accurately fit on the outside of the battery module B when it descends; the steel strip A on the pickup assembly 21 is also aligned with the pushing steel strip block 234 and the support block 235 of the pushing steel strip assembly 23, ensuring that when the adapter 233 moves the pushing steel strip block 234 and the support block 235 closer to the steel strip A on the pickup assembly 21, the steel strip A can accurately enter between the pushing steel strip block 234 and the support block 235; then, the first driving member 232 drives the adapter 233 to move the pushing steel strip block 234 and the support block 235 closer to the steel strip A on the pickup assembly 21 until the steel strip A on the pickup assembly 21 enters between the pushing steel strip block 234 and the support block 235; Then, the lifting drive 231 drives the adapter 233 and its pusher block 234 and support block 235 to descend together, so that the pusher block 234 pushes the steel strip A downward relative to the pickup component 21, so that the steel strip A gradually separates from the pickup component 21 and is placed on the outside of the battery module B. After the steel strip A is in place, the lifting drive 231 stops driving the adapter 233 and its pusher block 234 and support block 235 to continue to descend, and the first drive 232 drives the adapter 233 to move the pusher block 234 and support block 235 away from the steel strip A placed on the outside of the battery module B, until the steel strip A exits the receiving space a1 between the pusher block 234 and support block 235. Then, the lifting drive 231 drives the adapter 233 and its pusher block 234 and support block 235 to rise together until they reach the initial position, in preparation for the next pusher block.

[0038] It should be noted that after the pusher block 234 pushes the steel strip A away from the pickup assembly 21, the steel strip A may fall downwards due to its own weight. In this embodiment, a support block 235 is provided below the pusher block 234 to support the steel strip A, preventing it from falling and ensuring that the steel strip A moves down smoothly and is accurately fitted onto the outside of the battery module B.

[0039] Optionally, two pusher belt assemblies 23 are configured, and the two pusher belt assemblies 23 are respectively arranged on both sides of the pickup assembly 21 in the first direction X1. The first direction X1 is... Figure 2 As shown in the diagram, the left and right directions are as follows. In actual use, firstly, the first drive member 232 of the left-side steel belt pusher assembly 23 drives the steel belt pusher block 234 and the support block 235 to move to the right until the steel belt A on the pickup assembly 21 enters between the steel belt pusher block 234 and the support block 235 of the left-side steel belt pusher assembly 23; simultaneously, the first drive member 232 of the right-side steel belt pusher assembly 23 drives the steel belt pusher block 234 and the support block 235 to move to the left until the steel belt A on the pickup assembly 21 enters between the right-side pusher block 234 and the support block 235. Between the pusher block 234 and the support block 235 of the steel strip assembly 23; then, the lifting drive 231 of the left pusher block 233 drives the left pusher block 234 and the support block 235 to descend. At the same time, the lifting drive 231 of the right pusher block 233 synchronously drives the right pusher block 234 and the support block 235 to descend, thereby synchronously pushing the steel strip A on the pickup assembly 21 to move down until the steel strip A separates from the pickup assembly 21 and is fitted onto the outside of the battery module B.

[0040] It should be noted that before fitting the steel strip A over the battery module B, the battery module B needs to be compressed to ensure that the inner dimension of the steel strip A is slightly larger than the outer dimension of the battery module B, thus ensuring that the steel strip A can fit over the battery module B. However, since the amount of compression of the battery module B may vary each time, meaning that the size of the battery module B may be different each time the steel strip A is fitted, there is a risk that the support block 235 may collide with the battery module B during the descent, potentially damaging the battery module B.

[0041] To prevent the support block 235 from damaging the battery module B, in some embodiments, each pusher belt assembly 23 further includes an elastic element 236, with the support block 235 movably connected to the adapter seat 233. The elastic element 236 abuts between the support block 235 and the adapter seat 233, providing a spring force that causes the support block 235 to tend to move closer to the steel strip A on the pickup assembly 21. Thus, during the process of the lifting drive 231 driving the pusher belt block 234 and the support block 235 to descend together, if the support block 235 collides with the battery module B, the support block 235 will overcome the spring force provided by the elastic element 236 under the pressure exerted by the battery module B, thereby avoiding a hard impact between the support block 235 and the battery module B, and thus preventing the support block 235 from damaging the battery module B.

[0042] Furthermore, the adapter 233 has a guide hole extending through it in the first direction X1. The pusher belt assembly 23 also includes a limiting rod 237 passing through the guide hole. One end of the limiting rod 237 is fixedly connected to the support block 235, and an elastic element 236 is sleeved on the limiting rod 237, with both ends of the elastic element 236 abutting against the adapter 233 and the support block 235 respectively. Thus, when the support block 235 is pressed by the battery module B, it can overcome the elastic force of the elastic element 236 and drive the limiting rod 237 to move along the guide hole, thereby achieving elastic floating of the support block 235 and preventing damage to the battery module B. Optionally, the elastic element 236 can be a spring, and the limiting rod 237 can be a limiting screw.

[0043] Specifically, in the same pusher belt assembly 23, when the support block 235 is not subjected to external force (i.e., the pressure generated by colliding with the battery module B), the end of the support block 235 facing the pickup assembly 21 protrudes from the pusher belt block 234 by a predetermined length along the first direction X1. That is, the distance between the pusher belt block 234 and the battery module B in the first direction X1 is greater than the distance between the support block 235 and the battery module B in the first direction X1, thereby ensuring that the gap between the pusher belt block 234 and the battery module B is large enough, and thus ensuring that the pusher belt block 234 will not collide with the battery module B.

[0044] Optionally, the side of the pusher block 234 facing the support block 235 (i.e., the lower side of the pusher block 234) has a positioning recess a2. In this way, the steel strip A entering between the pusher block 234 and the support block 235 is confined within the positioning recess a2 of the pusher block 234, preventing the steel strip A from shifting position during its downward movement and ensuring that the steel strip A can be accurately fitted onto the outside of the battery module B. It should be noted that the positioning recess a2 can be an arc-shaped groove.

[0045] Optionally, the support block 235 has a positioning recess a2 on the side facing the pusher block 234 (i.e., the upper side of the support block 235). In this way, the steel strip A, which enters between the pusher block 234 and the support block 235, is confined within the positioning recess a2 of the support block 235, preventing the steel strip A from shifting position during its downward movement and ensuring that the steel strip A can be accurately fitted onto the outside of the battery module B. It should be noted that the positioning recess a2 can be an arc-shaped groove.

[0046] Please continue reading Figures 1 to 3 In the embodiments of this application, the pickup component 21 includes a transfer seat 210 and a plurality of expansion rods 2123 all disposed on the transfer seat 210. Each expansion rod 2123 extends downward to the lower part of the transfer seat 210. Each expansion rod 2123 can be in an outwardly expanded state relative to the transfer seat 210 and can also be in an inwardly contracted state relative to the transfer seat 210. Thus, when steel strip A needs to be picked up, firstly, each of the support rods 2123 moves closer to each other relative to the transfer seat 210 and is in an inward contraction state, so that the outer contour formed by the support rods 2123 together is smaller than the inner dimension of steel strip A, ensuring that steel strip A can be fitted onto the outside of all the support rods 2123; then, each of the support rods 2123 moves away from each other relative to the transfer seat 210 and is in an outward expansion state, thereby using each of the support rods 2123 to open and tension steel strip A. On the one hand, the support rods 2123 open steel strip A, so that steel strip A is fastened to each of the support rods 2123; on the other hand, it ensures that steel strip A is in a tensioned state, so that steel strip A can be fitted onto battery module B.

[0047] It should be noted that the tension steel strip A is opened by each of the support rods 2123, and the steel strip A is pushed downward along the support rods 2123 by the pusher blocks 234 of each pusher steel strip assembly 23, so that it gradually separates from each of the support rods 2123 and gradually fits onto the battery module B below, thereby realizing the packaging of the battery module B.

[0048] In some embodiments, the pickup assembly 21 further includes two support assemblies 212 spaced apart along a first direction X1 on the transfer seat 210. Each support assembly 212 includes a drive unit 2121 mounted on the transfer seat 210 and two spreading rods 2123 connected to the drive end of the drive unit 2121 and spaced apart along a second direction X2. That is, there are four spreading rods 2123, arranged in pairs. The two pairs of spreading rods 2123 are spaced apart along the first direction X1. Two spreading rods 2123 in the same pair are connected to the same drive unit 2121 and spaced apart along the second direction X2. The cross-section of the battery module B is approximately rectangular, so the four spreading rods 2123 also enclose a generally rectangular space, thereby spreading the steel strip A into a rectangle and ensuring that the steel strip A can be fitted over the outside of the battery module B. The first direction X1 and the second direction X2 are both perpendicular to the vertical direction and intersect each other. Preferably, the first direction X1, the second direction X2, and the vertical direction are perpendicular to each other.

[0049] The drive unit 2121 drives two connected support rods 2123 to produce a unidirectional displacement in a first direction X1 and a reverse displacement in a second direction X2. Under the driving action of the drive unit 2121, the two connected support rods 2123 produce a unidirectional displacement in the first direction X1, causing the two support rods 2123 connected to the other support assembly 212 to move closer or further away from each other along the first direction X1, thereby causing the two sets of support rods 2123 to loosen or expand the steel strip A along the first direction X1. Simultaneously, under the driving action of the drive unit 2121, the two connected support rods 2123 produce a reverse displacement in the second direction X2, causing the two support rods 2123 to loosen or expand the steel strip A along the second direction X2.

[0050] Thus, when it is necessary to pick up the steel strip A, firstly, the drive units 2121 of the two support components 212 drive the two sets of spreading rods 2123 to move, so that the two sets of spreading rods 2123 move closer to each other in the first direction X1. At the same time, the two spreading rods 2123 of each support component 212 move closer to each other in the second direction X2, so that the steel strip A can be sleeved on the outside of the four spreading rods 2123. Then, the drive units 2121 of the two support components 212 drive the two sets of spreading rods 2123 to move in opposite directions, so that the two sets of spreading rods 2123 move away from each other in the first direction X1. At the same time, the two spreading rods 2123 of each support component 212 move away from each other in the second direction X2, so that the two sets of spreading rods 2123 simultaneously spread the steel strip A along the first direction X1 and the second direction X2, thereby making the steel strip A tensioned and fixed on the two sets of spreading rods 2123, thus realizing the picking up of the steel strip A.

[0051] In a specific embodiment, each support component 212 further includes a tensioning unit 2125, which includes a tensioning drive 2126, a first tensioning plate 2127, and a second tensioning plate. The tensioning drive 2126 is mounted on the transfer seat 210, and the first tensioning plate 2127 and the second tensioning plate are respectively mounted on the two driving ends of the tensioning drive 2126 and are spaced apart along the second direction X2. The tensioning drive 2126 is used to drive the first tensioning plate 2127 and the second tensioning plate to move closer or further away along the second direction X2. The tensioning drive 2126 drives the first tensioning plate 2127 and the second tensioning plate to move away from each other along the second direction X2 until the first tensioning plate 2127 and the second tensioning plate are spread apart along the second direction X2 and tension the steel strip A sleeved on the outside of each spreading rod 2123, so that the spread steel strip A can be accurately sleeved on the outside of the battery module B when it moves down. Optionally, the tensioning drive 2126 can be a cylinder.

[0052] It is understood that in the same support assembly 212, the first tension plate 2127 and the second tension plate are located on one side of the two spreading rods 2123 facing the two spreading rods 2123 of the other support assembly 212. That is, the first tension plate 2127 and the second tension plate are located between the two spreading rods 2123 of one support assembly 212 and the two spreading rods 2123 of the other support assembly 212.

[0053] In a specific embodiment, the transfer seat 210 includes a seat body 2101, a fixed sub-seat 2103, a movable sub-seat 2105, and a motion drive 2107. The fixed sub-seat 2103 is fixedly connected to the seat body 2101, and a support component 212 is disposed on the fixed sub-seat 2103. The movable sub-seat 2105 is movably connected to the seat body 2101 along a first direction X1. The motion drive 2107 is disposed on the seat body 2101 and connected to the movable sub-seat 2105, so that the motion drive 2107 can drive the movable sub-seat 2105 to move relative to the seat body 2101 along the first direction X1. Another support component 212 is disposed on the motion sub-base 2105, enabling the motion sub-base 2105 to move its support component 212 closer to or further away from the support component 212 on the fixed sub-base 2103 along the first direction X1. This, in turn, causes the two sets of spreading rods 2123 to move closer to or further away from each other, thus adjusting the distance between the two sets of spreading rods 2123 to accommodate steel strips of different specifications A and improve the compatibility of the equipment. It should be noted that the motion drive component 2107 can be a linear drive module such as an electric cylinder or a linear motor, as long as it can drive the motion sub-base 2105 to adjust its position relative to the base body 2101 along the first direction X1. No limitation is imposed here.

[0054] It should be noted that the lifting drive 231 of one of the steel belt pusher assemblies 23 is mounted on the fixed sub-base 2103. The lifting drive 231 of the other steel belt pusher assembly 23 is mounted on the moving sub-base 2105, so that the steel belt pusher assembly 23 can adjust its position along the first direction X1 together with the moving sub-base 2105, so that the relative position of the steel belt pusher assembly 23 and the support assembly 212 on the moving sub-base 2105 remains unchanged.

[0055] Please see also Figure 7 As shown, in a specific embodiment, each drive unit 2121 includes a first movable seat 21211, a second movable seat 21212, a second drive member 21213, and a moving block 21214. The first movable seat 21211 is movably connected to the fixed sub-seat 2103 or the moving sub-seat 2105 of the transfer seat 210 along a first tilting direction. The second movable seat 21212 is movably connected to the fixed sub-seat 2103 or the moving sub-seat 2105 of the transfer seat 210 along a second tilting direction. The first tilting direction is tilted to one side relative to the first direction X1 (e.g., tilted by 30°, 45°, or 60°, etc.), and the second tilting direction is tilted to the opposite side relative to the first direction X1 (e.g., tilted by 30°, 45°, or 60°, etc.).

[0056] The second driving member 21213 is mounted on the fixed sub-base 2103 or the moving sub-base 2105 of the transfer seat 210. The moving block 21214 is connected to the driving end of the second driving member 21213, so that the second driving member 21213 can drive the moving block 21214 to move relative to the transfer seat 210 along the first direction X1. One end of the first moving seat 21211 is movably connected to the moving block 21214 along the second direction X2, and the other end of the first moving seat 21211 is connected to the corresponding spreading rod 2123. One end of the second moving seat 21212 is movably connected to the moving block 21214 along the second direction X2, and the other end of the second moving seat 21212 is connected to the corresponding spreading rod 2123. Optionally, the second driving member 21213 can be a cylinder.

[0057] Thus, when the second driving member 21213 drives the moving block 21214 to move relative to the transfer seat 210 along the first direction X1, the moving block 21214 drives the first moving seat 21211 and the second moving seat 21212 to move along the first tilting direction and the second tilting direction, respectively. The first moving seat 21211 drives the supporting rod 2123 connected to it to move along the first tilting direction, while the second moving seat 21212 drives the supporting rod 2123 connected to it to move along the second tilting direction. This allows the two supporting rods 2123 to move closer to or further away from another set of supporting rods 2123 along the first direction X1, while the two supporting rods 2123 move closer to or further away from each other along the second direction X2.

[0058] Specifically Figure 2 In the illustrated embodiment, when steel strip A needs to be picked up, firstly, for the left support assembly 212: when the second drive member 21213 drives the moving block 21214 to move to the right along the first direction X1, the moving block 21214 drives the first moving seat 21211 and the second moving seat 21212 to move to the right along the first tilting direction and the second tilting direction, respectively. Thus, the first moving seat 21211 and the second moving seat 21212 respectively drive the two spreading rods 2123 to move to the right along the first direction X1 (i.e., move closer to another set of spreading rods 2123) while also moving closer to each other along the second direction X2; at the same time, for the right support assembly... Component 212: When the second driving component 21213 drives the moving block 21214 to move to the left along the first direction X1, the moving block 21214 drives the first moving seat 21211 and the second moving seat 21212 to move to the left along the first tilting direction and the second tilting direction, respectively. The first moving seat 21211 and the second moving seat 21212 drive the two spreading rods 2123 to move to the left along the first direction X1 (i.e., move closer to another set of spreading rods 2123) and at the same time move closer to each other along the second direction X2, so that each spreading rod 2123 is in an inward contraction state, ensuring that the steel strip A can be smoothly fitted onto the outside of each spreading rod 2123.

[0059] Then, for the left-side support assembly 212: when the second drive member 21213 drives the moving block 21214 to move to the left along the first direction X1, the moving block 21214 drives the first moving seat 21211 and the second moving seat 21212 to move to the left along the first tilt direction and the second tilt direction, respectively. The first moving seat 21211 and the second moving seat 21212 drive the two spreading rods 2123 to move to the left along the first direction X1 (i.e., away from the other set of spreading rods 2123) while also moving away from each other along the second direction X2; at the same time, for the right-side support assembly 212... When the second driving member 21213 drives the moving block 21214 to move to the right in the first direction X1, the moving block 21214 drives the first moving seat 21211 and the second moving seat 21212 to move to the right in the first and second tilt directions respectively. The first moving seat 21211 and the second moving seat 21212 drive the two spreading rods 2123 to move to the right in the first direction X1 (i.e., move away from the other set of spreading rods 2123) and move away from each other in the second direction X2, so that each spreading rod 2123 is in an outward expansion state to open and tension the fixed steel strip A.

[0060] Please continue reading Figure 7Specifically, in this embodiment, the moving block 21214 has a first strip-shaped hole b1 extending longitudinally along the second direction X2. A first follower roller c1 is mounted on the first movable seat 21211. The first follower roller c1 rolls within the first strip-shaped hole b1 on the moving block 21214, so that while the moving block 21214 drives the first movable seat 21211 to move along the first inclined direction via the first follower roller c1, the first follower roller c1 rolls along the first strip-shaped hole b1, thus preventing the moving block 21214 from obstructing the movement of the first movable seat 21211 along the first inclined direction. In other words, through the rolling cooperation of the first follower roller c1 and the first strip-shaped hole b1, the linear motion of the moving block 21214 along the first direction X1 is converted into the linear motion of the first movable seat 21211 along the first inclined direction.

[0061] Specifically, in this embodiment, the moving block 21214 has a second strip-shaped hole b2 extending longitudinally along the second direction X2. A second follower roller c2 is mounted on the second movable seat 21212. The second follower roller c2 rolls within the second strip-shaped hole b2 on the moving block 21214, so that while the moving block 21214 drives the second movable seat 21212 to move along the second inclined direction via the second follower roller c2, the second follower roller c2 rolls along the second strip-shaped hole b2, thus preventing the moving block 21214 from obstructing the movement of the second movable seat 21212 along the second inclined direction. In other words, through the rolling cooperation of the second follower roller c2 and the second strip-shaped hole b2, the linear motion of the moving block 21214 along the first direction X1 is converted into the linear motion of the second movable seat 21212 along the second inclined direction.

[0062] Specifically, in the embodiment, the fixed sub-base 2103 or the moving sub-base 2105 of the transfer seat 210 is provided with a first guide rail extending longitudinally along the first inclined direction, and the first moving seat 21211 is provided with a first slider. The first slider slides on the first guide rail, thereby guiding the movement of the first moving seat 21211 by sliding the first slider along the first guide rail, ensuring that the first moving seat 21211 moves relative to the transfer seat 210 along the first inclined direction under the drive of the moving block 21214. The guiding structure is simple and reliable, which helps to reduce equipment costs.

[0063] Specifically, in the embodiment, the fixed sub-base 2103 or the moving sub-base 2105 of the transfer seat 210 is provided with a second guide rail extending longitudinally along the second inclined direction, and the second moving seat 21212 is provided with a second slider. The second slider slides on the second guide rail, thereby guiding the movement of the second moving seat 21212 by sliding the second slider along the second guide rail, ensuring that the second moving seat 21212 moves relative to the transfer seat 210 along the second inclined direction under the drive of the moving block 21214. The guiding structure is simple and reliable, which helps to reduce equipment costs.

[0064] Please continue reading Figure 1 , Figure 9 and Figure 10 In the embodiments of this application, the steel strip fitting device 1 further includes a drive mechanism 30 and a steel strip positioning mechanism 60. The steel strip positioning mechanism 60 is arranged at the pickup position for providing steel strip A. The seat body 2101 of the steel strip fitting mechanism 20 is mounted on the drive end of the drive mechanism 30, enabling the drive mechanism 30 to drive the steel strip fitting mechanism 20 to move between the pickup position and the steel strip fitting position. When the drive mechanism 30 drives the steel strip fitting mechanism 20 to the pickup position, the steel strip A on the steel strip positioning mechanism 60 is opened and tensioned by the various expansion rods 2123 of the steel strip fitting mechanism 20. When the drive mechanism 30 drives the steel belt mounting mechanism 20 to move to the steel belt mounting position, the steel belt mounting mechanism 20 is located on top of the battery module B on the loading mechanism 10. Thus, under the driving action of the lifting drive 231 of the two steel belt pushing assemblies 23, the two steel belt pushing blocks 234 push the steel belt A mounted on each of the support rods 2123 to move down until the steel belt A is mounted on the battery module B below.

[0065] Specifically, in this embodiment, the driving mechanism 30 includes a first driving module 31, a second driving module 33, and a third driving module 35. The second driving module 33 is mounted on the driving end of the first driving module 31, the third driving module 35 is mounted on the driving end of the second driving module 33, and the seat body 2101 of the steel belt mounting mechanism 20 is mounted on the driving end of the third driving module 35. The first driving module 31 drives the second driving module 33 to move along the second direction X2, the second driving module 33 drives the third driving module 35 to move along the first direction X1, and the third driving module 35 drives the steel belt mounting mechanism 20 to rise or fall. Thus, by using the first driving module 31 to drive the steel belt mounting mechanism 20 to move along the second direction X2, the steel belt mounting mechanism 20 can move between the pickup position and the steel belt mounting position.

[0066] At the pickup position: the second drive module 33 drives the steel strip mechanism 20 to adjust its position along the first direction X1, ensuring that each expansion rod 2123 is aligned with the steel strip A on the steel strip positioning mechanism 60; the third drive module 35 drives the steel strip mechanism 20 to descend, so that each expansion rod 2123, which is in an inward contraction state, is inserted into the inside of the steel strip A on the steel strip positioning mechanism 60; under the driving action of the drive unit 2121, each expansion rod 2123 is in an outward expansion state, thereby opening and tensioning the steel strip A; then the third drive module 35 drives the steel strip mechanism 20 to rise, so that the steel strip A rises together with each expansion rod 2123 and separates from the steel strip positioning mechanism 60, thus realizing the pickup of the steel strip A.

[0067] At the steel strip mounting position: the second drive module 33 drives the steel strip mounting mechanism 20 to adjust its position along the first direction X1, ensuring that the steel strip A, which is tensioned and fixed on each of the support rods 2123, is aligned with the battery module B on the loading mechanism 10; the third drive module 35 drives the steel strip mounting mechanism 20 to descend until the bottom of each support rod 2123 is close enough to the battery module B below; under the driving action of the two lifting drive components 231, the two pushing steel strip blocks 234 simultaneously push the steel strip A, which is tensioned and fixed on each of the support rods 2123, to move down along the support rods 2123 until the steel strip A is pushed downward and mounted on the outside of the battery module B; then the third drive module 35 drives the steel strip mounting mechanism 20 to rise and reset.

[0068] It should be noted that the first drive module 31, the second drive module 33 and the third drive module 35 can all be linear drive modules such as electric cylinders or linear motors, and no special restrictions are made here.

[0069] In a specific embodiment, the steel strip packaging device 1 further includes a conveying mechanism 40, on which the loading mechanism 10 is mounted. The conveying mechanism 40 is used to move the loading mechanism 10 between the loading position and the steel strip packaging position. When the conveying mechanism 40 moves the loading mechanism 10 to the loading station, the battery module B to be packaged is transferred onto the loading mechanism 10 by a loading mechanism such as a robotic arm. When the conveying mechanism 40 moves the loading mechanism 10 to the steel strip packaging position, the battery module B on the loading mechanism 10 is located below the steel strip packaging mechanism 20, which has reached the steel strip packaging position, so that the steel strip packaging mechanism 20 can wrap the steel strip A downwards onto the outside of the battery module B.

[0070] In a specific embodiment, the steel belt sheathing device 1 further includes a positioning mechanism 70, which is arranged corresponding to the position of the steel belt sheathing. When the conveying mechanism 40 transports the loading mechanism 10 to the position of the steel belt sheathing, the loading mechanism 10 is located above the positioning mechanism 70. The positioning mechanism 70 is used to position the loading mechanism 10 above it, thereby ensuring that the positional accuracy of the loading mechanism 10 meets the process requirements.

[0071] It should be noted that in some embodiments, the positioning mechanism 70 is provided with multiple positioning posts, and the loading mechanism 10 is provided with multiple positioning holes. When the conveying mechanism 40 conveys the loading mechanism 10 to the position of the steel belt, the positioning mechanism 70 drives each positioning post to rise until each positioning post is inserted into the corresponding positioning hole on the loading mechanism 10, thereby achieving the positioning of the loading mechanism 10.

[0072] Please see also Figure 8In the embodiments of this application, the loading mechanism 10 includes a mounting base 11, a support member 12, a first pressing block 13, and a second pressing block 14. The support member 12 is disposed on the mounting base 11 and is used to support the battery module B. The first pressing block 13 and the second pressing block 14 are both disposed on the mounting base 11 and are respectively arranged at both ends of the support member 12 in a first direction X1. At least one of the first pressing block 13 and the second pressing block 14 can move closer to or further away from the other. Thus, after the battery module B is loaded onto the support member 12, at least one of the first pressing block 13 and the second pressing block 14 moves closer to the other, so that the first pressing block 13 and the second pressing block 14 press the battery module B between them until the compression of the battery module B reaches a preset value. After the steel strip A on the pickup assembly 21 is pushed down by the steel strip pusher block 234 of the steel strip pusher assembly 23 and fitted onto the outside of the battery module B, at least one of the first pressure block 13 and the second pressure block 14 moves away from the other to release the pressure on the battery module B, so that the external dimensions of the battery module B return to the state before it was pressed, thereby tightening the steel strip A fitted onto its outside.

[0073] In some embodiments, the loading mechanism 10 further includes a transmission assembly 15 disposed on the mounting base 11. The transmission assembly 15 is connected to the first pressure block 13. The steel belt sheathing device 1 further includes a clamping drive mechanism 50 arranged corresponding to the steel belt sheathing position. The clamping drive mechanism 50 includes a base 51, a docking drive member 52, a mounting support 53, and a clamping drive member 54. The mounting support 53 is movably connected to the base 51 along a first direction X1. The docking drive member 52 is mounted on the base 51, and the driving end of the docking drive member 52 is connected to the mounting support 53, so that the docking drive member 52 can drive the mounting support 53 to move along the first direction X1. The clamping drive member 54 is mounted on the mounting support 53, so that the clamping drive member 54 can move together with the mounting support 53. When the conveying mechanism 40 conveys the loading mechanism 10 to the steel belt sheathing position, under the driving action of the docking drive member 52, the mounting support 53 can drive the clamping drive member 54 to move along the first direction X1 to dock with or separate from the transmission assembly 15. When the clamping drive 54 engages with the transmission assembly 15, the power output by the clamping drive 54 is transmitted to the first pressure block 13 through the transmission assembly 15, thereby driving the first pressure block 13 to move closer to or away from the second pressure block 14, so that the first pressure block 13 and the second pressure block 14 press or release the battery module B between them. When the clamping drive 54 separates from the transmission assembly 15, the conveying mechanism 40 can transport the loading mechanism 10 away from the steel belt position, and the clamping drive 54 will not interfere with the movement of the loading mechanism 10.

[0074] Optionally, the transmission assembly 15 includes a lead screw 151 and a lead screw nut. The lead screw 151 is rotatably connected to the mounting base 11, and the axial direction of the lead screw 151 is aligned with the first direction X1. The lead screw nut is threaded onto the lead screw 151 and fixedly connected to the first pressure block 13, so that when the lead screw 151 rotates, it can drive the lead screw nut to move along the first direction X1, and the lead screw nut in turn drives the first pressure block 13 to move closer to or away from the second pressure block 14 along the first direction X1.

[0075] When the conveyor mechanism 40 moves the loading mechanism 10 to the steel belt position, under the driving action of the docking drive member 52, the mounting support 53 can drive the clamping drive member 54 to move to dock with or disengage from the transmission screw 151 of the transmission assembly 15. When the clamping drive member 54 docks with the transmission screw 151 of the transmission assembly 15, the clamping drive member 54 can drive the transmission screw 151 to rotate. Optionally, the clamping drive member 54 can be a motor.

[0076] Furthermore, a wrench 55 is mounted on the drive end of the clamping drive member 54, and a rotating wheel 152 is mounted on the transmission screw 151. The wrench 55 is used to engage with the rotating wheel 152, so that when the clamping drive member 54 drives the wrench 55 to rotate, the wrench 55 can drive the rotating wheel 152 to rotate, and the rotating wheel 152 in turn drives the transmission screw 151 to rotate. The specific structure of the wrench 55 and the rotating wheel 152 is not limited here, as long as the transmission of rotational motion can be achieved.

[0077] In a specific embodiment, the loading mechanism 10 further includes a plurality of steel strip support portions 17 disposed on the mounting base 11. Each steel strip support portion 17 is arranged around the aforementioned support member 12 and is used to support the steel strip A. The height of each steel strip support portion 17 is lower than the height of the support member 12, such that the steel strip A supported on each steel strip support portion 17 is arranged around the battery module B and located below the battery module B. It should be noted that a loading mechanism such as a robotic arm can be used to load the steel strip A onto each steel strip support portion 17.

[0078] The steel strip fitting device 2 is located below the steel strip fitting position. When the loading mechanism 10 moves to the steel strip fitting position, the steel strip fitting device 2 is located below the loading mechanism 10. The steel strip fitting device 2 is used to pick up the steel strip A on each steel strip support 17 and push the picked-up steel strip A upward until the steel strip A is fitted onto the outside of the battery module B from bottom to top.

[0079] It should be noted that the steel strip device 2 can also pick up the steel strip A by using multiple spreading rods to spread and tension the steel strip A, or it can pick up the steel strip A by clamping. No special limitation is made here.

[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
