Description

Technical Field

[0002] In traditional new energy vehicle battery pack production lines, after the battery pack is assembled with the battery modules, a top cover needs to be installed on top of the battery pack's lower shell to achieve the battery pack's sealing and waterproofing functions. Specifically: First, a high-strength sealing and waterproof glue is evenly applied to the outer periphery of the battery pack's top cover, and then the glue-coated battery pack top cover is moved to the next station; after the battery pack top cover is moved to the next station, multiple operators use a suction cup bracket to remove the battery pack top cover and manually load it, and at least one operator is required to direct it; after the battery pack top cover is accurately placed, a load-bearing block is used to press the glue-coated battery pack top cover against the battery pack's lower shell to achieve a sealing effect between the battery pack's top cover and the battery pack's lower shell. The entire process requires high operating skills, collaboration capabilities, and equipment accuracy from the operators.

[0003] However, since the battery pack cover is manually loaded after being coated with glue, the production line needs to be stopped when the operator transfers the battery pack cover, resulting in a production line availability of only 68%. In addition, the high-rigidity sealant at the edge of the battery pack cover is easily colliding with surrounding objects and falling off. To avoid quality problems such as poor sealing, the entire high-rigidity sealant on the battery pack cover must be scraped off and re-coated before continuing the operation, resulting in low battery pack assembly production efficiency.

[0038] The utility model provides a battery pack carrying device and a production line.

[0039] See also Figure 1 、 Figure 2 and Figure 3 In one embodiment of the present invention, the battery pack loading device includes a base 100, a top loading mechanism 200, a bottom loading mechanism 300 and a pick-and-place mechanism 500. The top loading mechanism 200 can be installed on the base 100 in a liftable manner; the bottom loading mechanism 300 is located below the top loading mechanism 200, and the bottom loading mechanism 300 can be floatingly suspended on the top loading mechanism 200 through a pulling mechanism 400. The pulling mechanism 400 is used to drive the bottom loading mechanism 300 to rise and fall relative to the top loading mechanism 200, so as to correspondingly make the bottom loading mechanism 300 approach or move away from the top loading mechanism 200; the pick-and-place mechanism 500 is installed on the bottom loading mechanism 300, and the pick-and-place mechanism 500 is used to pick up and place the battery pack, so as to correspondingly load the battery pack on the bottom of the bottom loading mechanism 300 or unload it from the bottom of the bottom loading mechanism 300.

[0040] Specifically, in the process of installing the battery pack upper cover 10 on the battery pack lower shell, first, the top-level loading mechanism 200 drives the bottom-level loading mechanism 300 installed thereunder to move downward relative to the base 100 in a direction away from the base 100, so that both the top-level loading mechanism 200 and the bottom-level loading mechanism 300 are close to the battery pack upper cover 10 located in the upper cover suction area; then the pulling mechanism 400 is used to extend the end of the pulling mechanism 400 connected to the bottom-level loading mechanism 300 downward to drive the bottom-level loading mechanism 300 to move downward in a direction away from the top-level loading mechanism 200, so that the bottom-level loading mechanism 300 is suspended above the battery pack upper cover 10 relative to the top-level loading mechanism 200; because the bottom-level loading mechanism 300 is in a suspended state, its position relative to the battery pack upper cover 10 can be manually adjusted, that is, it can be adjusted in the longitudinal and transverse directions in the horizontal direction, as well as in the vertical direction, and the bottom-level loading mechanism 300 can The pick-and-place mechanism 500 is tilted or horizontal relative to the battery pack upper cover 10, so that the pick-and-place mechanism 500 installed on the bottom loading mechanism 300 can adapt to battery pack upper covers 10 of different sizes and shapes, thereby increasing the ability of the pick-and-place mechanism 500 to adapt to different battery pack upper covers 10, and reducing the difficulty of positioning the battery pack upper cover 10, thereby improving the installation accuracy and efficiency of the battery pack upper cover 10 on the battery pack lower shell; after the battery pack upper cover 10 is loaded on the bottom loading mechanism 300 through the pick-and-place mechanism 500, the pulling mechanism 400 is used to shorten the end of the pulling mechanism 400 connected to the bottom loading mechanism 300 upward, so as to drive the bottom loading mechanism 300 to move upward toward the direction close to the top loading mechanism 200, so that the bottom loading mechanism 300 abuts against the lower side of the top loading mechanism 200, so that the battery pack upper cover 10 taken by the pick-and-place mechanism 500 is loaded on the battery pack loading equipment and transferred to the next workstation through the battery pack loading equipment.

[0041] In the technical solution of the present invention, a bottom loading mechanism 300 is used to be floatingly suspended on a top loading mechanism 200 by a pulling mechanism 400, so that the bottom loading mechanism 300 can move in multiple directions relative to the top loading mechanism 200 when the battery pack upper cover 10 is taken and placed by the pick-and-place mechanism 500, so that the battery pack loading device can adapt to battery pack upper covers 10 of different sizes and shapes, reduce hard contact and collision with the battery pack upper cover 10, increase the ability to adapt to different battery pack upper covers 10, and improve the efficiency of transferring the battery pack upper cover 10, so as to improve the assembly production efficiency of the battery pack.

[0042] Please continue reading Figure 3 , and refer to Figure 7 and Figure 8In an embodiment of the present invention, more specifically, the battery pack loading device further includes a mounting mechanism 600, which is mounted on the top loading mechanism 200. The mounting mechanism 600 has a lifting drive component 610. When the battery pack is unloaded from the bottom of the bottom loading mechanism 300, the lifting drive component 610 is used to drive the bottom loading mechanism 300 to press the upper cover of the battery pack. After the battery pack loading equipment drives the battery pack upper cover 10 to transfer to the next workstation, repeat the above steps and use the pulling mechanism 400 to extend one end of the pulling mechanism 400 connected to the bottom loading mechanism 300 downward, so that the bottom loading mechanism 300 drives the battery pack upper cover 10 installed on the pick-and-place mechanism 500 to move downward in the direction away from the top loading mechanism 200 to the battery pack lower shell. After the battery pack upper cover 10 and the battery pack lower shell are aligned, the battery pack upper cover 10 is unloaded from the pick-and-place mechanism 500, and the telescopic end of the installation mechanism 600 is used to squeeze the battery pack upper cover 10 downward so that the battery pack upper cover 10 and the battery pack lower shell are sealed by sealant to complete the assembly of the battery pack. By using the installation mechanism 600 with the lifting drive part 610, after the battery pack upper cover 10 and the battery pack lower shell are aligned, the battery pack upper cover 10 is pressed downward by the lifting drive part 610, so that the battery pack upper cover 10 and the battery pack lower shell are tightly connected by the sealant. The mechanized pressing action ensures uniform pressure, avoids manual operation errors, and improves the sealing quality during the battery pack assembly production process.

[0043] In the embodiment of the present invention, the mounting mechanism 600 can be implemented in various forms. In the embodiment of the present invention, a plurality of horizontally spaced pressing plates 320 are mounted on the bottom mounting mechanism 300. The number of mounting mechanisms 600 is equal to the number of pressing plates 320 and is arranged one-to-one with each other. Each mounting mechanism 600 includes a lifting drive 610 and a connecting seat 620. The lifting drive 610 is mounted on the top mounting mechanism 200 via the connecting seat 620. The output end of the lifting drive 610 forms a telescopic end. Specifically, the plurality of spaced pressing plates 320 are mounted on the bottom mounting mechanism 300 so that during the installation of the battery pack upper cover 10, multiple areas of the upper cover can be pressed. The plurality of pressing plates 320 ensures uniform pressure distribution on the upper cover during installation. The uniform pressure distribution ensures that the sealant is evenly compressed, thereby improving the sealing effect, avoiding water and air leakage caused by poor sealing, and avoiding pressure concentration at a single point or a small number of points, preventing deformation or damage of the upper cover, thereby improving the installation quality. In addition, the design of multiple pressing plates 320 allows the device to be flexibly adjusted according to upper covers of different sizes, thereby increasing the adaptability of the device and meeting the installation requirements of upper covers 10 of battery packs of different types and specifications.

[0044] Each mounting mechanism 600 independently controls a pressing plate 320, enabling precise control of the pressing of each pressing plate 320 to ensure synchronization and consistency during the pressing process. Due to the independence between the pressing plate 320 and the mounting mechanism 600, flexible adjustments can be made to meet different installation requirements. For example, different pressure values ​​can be set for different areas of the battery pack to further optimize the installation effect. In addition, during the installation of the upper cover, the mounting mechanism 600 can achieve segmented pressure application, that is, gradually applying pressure to different areas as needed, avoiding excessive stress caused by one-time pressure application and improving the stability and reliability of the installation.

[0045] It should be noted that the lifting drive member 610 can be an electric push rod, a motor connected to a gear set, or a hydraulic cylinder or pneumatic cylinder with a movable end in the prior art.

[0046] Please continue to refer to Figure 3 、 Figure 7 and Figure 8 More specifically, in an embodiment of the present invention, the battery pack mounting device further includes a plurality of buffer blocks 330, which are installed horizontally at intervals at the bottom of the bottom mounting mechanism 300, and each of the buffer blocks 330 extends vertically. The multiple buffer blocks 330 arranged at intervals can evenly distribute pressure. During the installation of the upper cover, the buffer blocks 330 can effectively absorb and buffer the impact force from the upper bottom mounting mechanism 300, i.e., the pressing plate 320, preventing direct and excessive stress concentration on the battery pack upper cover 10, reducing the risk of deformation and damage to the upper cover, and preventing adverse effects of vibration on the upper cover and the bottom mounting mechanism 300, thereby improving the smoothness of the overall installation process.

[0047] As an optional implementation of this embodiment, a gap is left between two adjacent buffer blocks 330. The number and spacing of the buffer blocks 330 can be adjusted according to actual needs to adapt to battery pack upper covers 10 of different sizes and shapes, thereby increasing the flexibility and adaptability of the equipment.

[0048] Please continue to refer to Figure 3In an embodiment of the present utility model, the pulling mechanism 400 can be implemented in many ways. The pulling mechanism 400 includes a first driving member 410, a steering mechanism 420 and a pulling rope 430. The first driving member 410 and the steering mechanism 420 are both installed on the top-level carrying mechanism 200, and the first driving member 410 extends in the horizontal direction; the first driving member 410 includes a fixed seat 411 and an output shaft 412, the connecting end 431 of the pulling rope 430 is connected to the fixed seat 411, and the free end 432 of the pulling rope 430 is connected to the bottom-level carrying mechanism 300 through the steering mechanism 420. The first driving member 410 is used to drive the pulling rope 430 in the horizontal direction through the output shaft 412, so that the pulling rope 430 drives the bottom-level carrying mechanism 300 to rise and fall after being turned by the steering mechanism 420.

[0049] The steering mechanism 420 is used to redirect the horizontal movement of the pulling rope 430 into vertical movement.

[0050] The first driving member 410 is hinged to the top-level carrying mechanism 200 through the fixed seat 411. The output shaft 412 of the first driving member 410 can drive the pulling rope 430 in the horizontal direction, reducing the mechanical components in the vertical direction, simplifying the structure, and reducing the vertical space requirements, making the entire equipment structure more compact, convenient for installation and operation in a limited space, and improving the precise control of lifting. When the bottom-level carrying mechanism 300 is close to the top-level carrying mechanism 200, the bottom-level carrying mechanism 300 can be more closely against the top-level carrying mechanism 200, thereby reducing the shaking of the battery pack cover when transporting the battery pack carried on the bottom-level carrying mechanism 300, thereby improving the production safety of the battery pack.

[0051] The pulling rope 430 serves as a flexible connector and can adapt to different spatial layouts under the action of the steering mechanism 420, thereby increasing the flexibility and adaptability of the equipment and enabling the bottom-layer carrying mechanism 300 to float relative to the top-layer carrying mechanism 200, thereby facilitating manual position adjustment and adapting to battery pack upper covers 10 of different sizes and shapes.

[0052] It should be noted that the first driving member 410 can be an electric push rod, a motor connected to a gear set, or a hydraulic cylinder or pneumatic cylinder with a movable end in the prior art. The pulling rope 430 can be a steel wire rope or other rope with both strength and toughness in the prior art.

[0053] Please continue to refer to Figure 3 Specifically, in an embodiment of the present invention, the steering mechanism 420 includes two fixed pulleys 421, both of which are arranged below the fixed seat 411. The two fixed pulleys 421 are installed on the top-level carrying mechanism 200 at intervals in the horizontal direction. A gap is formed between the two fixed pulleys 421, and the free end 432 of the pulling rope 430 is connected to the bottom-level carrying mechanism 300 through the gap.

[0054] The fixed pulley 421 is used to change the movement direction of the lifting rope 430. The fixed pulley 421 reduces the friction of the lifting rope 430 during the turning process, reduces energy loss, improves lifting efficiency, and ensures that the lifting rope 430 will not get stuck or worn due to direction changes during movement, thereby improving the reliability and stability of the equipment, so that the horizontally driven lifting rope 430 can realize vertical force transmission through the turning of the fixed pulley 421, and the gap serves as a channel for the lifting rope 430 to pass through, providing a stable passage for the lifting rope 430, avoiding the lifting rope 430 from deflecting or detaching during the turning process, improving the stability of operation, and ensuring that the lifting rope 430 passes smoothly between the two fixed pulleys 421 to connect to the underlying carrying mechanism 300, thereby accurately realizing force transmission and movement turning.

[0055] Please continue reading Figure 3 More specifically, in an embodiment of the present utility model, the steering mechanism 420 further includes a pulley seat 422 and a movable pulley 423. The movable pulley 423 is rotatably mounted on the pulley seat 422. The pulley seat 422 is mounted on the output shaft 412 of the first driving member 410. The free end 432 of the lifting rope 430 revolves around the movable pulley 423 and is connected to the bottom carrying mechanism 300 through the gap, and the lifting rope 430 slides with the movable pulley 423. The first driving member 410 is used to drive the pulley seat 422 and the movable pulley 423 in the horizontal direction through the output shaft 412, so that the lifting rope 430 drives the bottom carrying mechanism 300 to rise and fall after being turned by the movable pulley 423.

[0056] After the free end 432 of the lifting rope 430 passes around the movable pulley 423, under the horizontal drive of the output shaft 412 of the first driving member 410, the movable pulley 423 moves horizontally with the pulley seat 422, so that the free end 432 of the lifting rope 430 can be extended and retracted relative to the movable pulley 423, so as to accurately control the lifting and lowering of the underlying carrying mechanism 300, providing higher control accuracy for the battery pack assembly production process. In addition, the movable pulley 423 ensures that the lifting rope 430 can slide smoothly during the turning process, reducing the safety hazards caused by jamming or rope breakage, and ensuring the stability, continuity and safety of the production process.

[0057] In an embodiment of the present invention, the top-level loading mechanism 200 includes a top-level frame 210 and a guide rail 220, the fixed seat 411 and the guide rail 220 are both installed on the top-level frame 210, the guide rail 220 extends in the horizontal direction, and the pulley seat 422 is slidably installed on the guide rail 220 in the horizontal direction.

[0058] Guide rail 220 extends horizontally, providing a stable and precise sliding path for pulley base 422. This prevents the pulley base 422 from shifting or shaking during sliding, thereby making the movement of the bottom mounting mechanism 300, which carries the battery pack cover, more precise and controllable. Furthermore, guide rail 220 reduces energy loss caused by friction or resistance in pulley base 422, thereby improving operating efficiency.

[0059] See also Figure 4 and Figure 5 In an embodiment of the present invention, there are many forms of implementation of the pick-and-place mechanism 500. The pick-and-place mechanism 500 includes a positioning structure 510 and a suction cup 520. The positioning structure 510 and the suction cup 520 are both installed on the bottom loading mechanism 300, and the positioning structure 510 and the suction cup 520 are arranged at intervals; the positioning structure 510 is used to position the battery pack; the suction cup 520 is used to absorb or release the battery pack, so as to correspondingly load the battery pack onto the bottom of the bottom loading mechanism 300 or unload it from the bottom of the bottom loading mechanism 300.

[0060] The positioning structure 510 is used to accurately position the battery pack, ensuring that the battery pack is accurately positioned during the loading process, so as to reduce installation errors caused by position deviations, thereby improving the accuracy and consistency of battery pack installation. The suction cup 520 is used to absorb or release the battery pack, so that the pick-and-place mechanism 500 can adapt to battery packs of different sizes and shapes. The flexibility of the suction cup 520 enables the device to handle battery packs of various specifications, increasing the versatility and flexibility of the device. The spacing between the positioning structure 510 and the suction cup 520 enables the pick-and-place mechanism 500 to complete the actions of positioning and absorbing / releasing the battery pack in the same operation step, reducing the number of operation steps, improving operation efficiency, and shortening the installation time of the battery pack.

[0061] As an optional implementation manner of this embodiment, there are two positioning structures 510, and the two positioning structures 510 are arranged opposite to each other along the diagonal line of the bottom mounting mechanism 300 to ensure that at least two of the four corner points of the battery pack upper cover 10 on the bottom mounting mechanism 300 are stably positioned, thereby further improving the overall positioning accuracy and stability of the battery pack, and can effectively prevent the battery pack upper cover 10 from rotating or tilting during the mounting process, ensuring the stability of the battery pack upper cover 10, which is conducive to improving the assembly production quality of the battery pack.

[0062] Please continue reading Figure 4 and Figure 5Specifically, in an embodiment of the present invention, a socket 11 is formed on the top of the battery pack; the positioning structure 510 is arranged corresponding to the socket 11; the positioning structure 510 includes a support 511 and an insertion rod assembly 530, the support 511 is installed on the bottom carrying mechanism 300, and the insertion rod assembly 530 is movably installed on the support 511, and the insertion rod assembly 530 is used to insert into the socket 11 to position the battery pack.

[0063] The insertion rod assembly 530 can move in the vertical and horizontal directions relative to the support 511, so that the positioning structure 510 can be aligned with the socket 11 on the top of the battery pack at different positions, so as to achieve precise positioning of the battery pack cover 10, greatly reduce the installation error caused by the position offset of the battery pack, ensure that the battery pack cover 10 can be accurately aligned, and improve the accuracy of the overall assembly of the battery pack. In addition, the insertion rod assembly 530 movably arranged relative to the support 511 can effectively buffer the shaking or displacement of the battery pack cover 10 during the positioning process, and ensure the position stability of the battery pack during the entire loading and installation process.

[0064] More specifically, in an embodiment of the present invention, the insertion rod assembly 530 includes a pin 512 and a limit plate 513. The limit plate 513 is movably mounted on the support 511 in the horizontal direction, and the pin 512 is slidably mounted on the limit plate 513 in the vertical direction. The pin 512 is used to be plugged into the socket 11 to position the battery pack.

[0065] A portion of the limiting plate 513 is inserted into the support 511 via a ball bearing, allowing the pin 512 mounted on the limiting plate 513 to be adjusted horizontally to accommodate the different horizontal positions of the socket 11 on the top of the battery pack cover 10. The pin 512 is slidably mounted on the limiting plate 513 vertically to allow the pin 512 to be adjusted in height vertically, ensuring that the pin 512 can be accurately inserted into the socket 11. Regardless of how the height of the socket 11 changes, precise alignment can be achieved, thereby improving the flexibility and adaptability of the alignment between the device and the battery pack cover 10. Furthermore, the pin 512 can be precisely adjusted in two dimensions to achieve precise alignment of the socket 11, significantly improving the positioning accuracy of the battery pack cover 10 and reducing installation errors.

[0066] In addition, the pin 512 is slidably installed on the limit plate 513 along the vertical direction. During the plugging process, the pin 512 can buffer the slight shaking of the battery pack, avoiding damage that may be caused by hard docking, and ensuring stability during the positioning process. The horizontal mobility of the limit plate 513 also allows fine-tuning after the pin 512 is inserted into the hole 11, thereby reducing the risk of displacement of the battery pack cover 10 during the entire installation process, and further ensuring the stability of the battery pack cover 10 during the loading and installation process.

[0067] Please continue reading Figure 1 and Figure 2 , and see Figure 6 In an embodiment of the present invention, the battery pack loading device further includes a clamping claw 700, which is hinged to the outer edge of the top loading mechanism 200 and can rotate relative to the top loading mechanism 200 between a clamping position and a release position to clamp or release the battery pack accordingly.

[0068] Specifically, during the battery pack loading process, when the battery pack is loaded on the bottom of the bottom loading mechanism 300, the clamping jaw 700 rotates to the clamping position to firmly clamp the battery pack. The clamping jaw 700 provides additional fixing force for the battery pack cover at the clamping position, effectively preventing the battery pack from shifting or falling off due to vibration or other external forces, and improving the stability and safety during the loading process. The clamping jaw 700 can rotate to a loose position to release the battery pack cover 10 when the battery pack is unloaded. When the clamping jaw 700 clamps the battery pack cover 10, it not only provides additional positioning for the battery pack cover 10 during the loading process, but also increases the adaptability of the equipment to battery packs of different specifications, expands the application range of the equipment, and provides more flexible production capacity.

[0069] As an alternative embodiment of this embodiment, one end of the clamping jaw 700 is connected to the output end of a second driving member. The fixed end of the second driving member is hinged to the top frame 210. The second driving member is used to drive the clamping jaw 700 to rotate between a clamping position and a release position relative to the top loading mechanism 200. The second driving member can be an electric push rod, a motor connected to a gear set, or a hydraulic cylinder or pneumatic cylinder with a movable end, as known in the art.

[0070] As another optional implementation of this embodiment, in order to prevent damage to the battery pack upper cover 10, a buffer pad is provided on the clamping jaw 700.

[0071] As a specific embodiment of the present utility model, in the prior art, the upper cover of the battery pack after being coated with glue is manually loaded, which has the following problems: when the upper cover is taken out, it is necessary to enter the equipment to perform the loading operation, which is likely to affect the life safety of the operator; when the operator takes out the upper cover, the conveyor line needs to be stopped, resulting in the movable rate of the conveyor line being only 68%; in the process of manually removing the upper cover, the high-rigidity sealant at its edge is easy to collide with surrounding objects, causing the sealant to fall off. If the upper cover with the sealant falling off is loaded onto the lower shell of the battery, quality problems such as poor sealing will occur. The thermal conductive glue of the entire upper cover must be completely removed and re-coated before the loading operation can be performed; an additional commander is required to direct the loading operation to prevent quality problems such as poor alignment of the upper cover during the loading process.

[0072] The battery pack loading device takes and places the battery pack cover by means of the bottom loading mechanism 300 suspended on the top loading mechanism 200, i.e., the top frame 210, the clamping claw 700 hinged on the top loading mechanism 200, and the pick-and-place mechanism 500 installed on the bottom loading mechanism 300, i.e., the bottom frame 310. When the battery pack loading device reaches the loading position of the battery pack cover 10, the top loading mechanism 200 drives the bottom loading mechanism 300 to descend to the initial adjustment position toward the battery pack cover 10. The bottom loading mechanism 300 is then lowered using the lifting mechanism 400, separating it from the top loading mechanism 200 and allowing it to float above the battery pack upper cover 10. The four sides of the bottom loading mechanism 300 are connected to the top loading mechanism 200 via the steel wire ropes in the lifting mechanism 400, and the multiple steel wire ropes are protected by anti-loosening brackets. This allows the operator to quickly position the battery pack upper cover 10 and the battery pack lower shell, and accurately position them using the positioning structure 510, eliminating the need for a supervisor. Furthermore, mounting mechanisms 600 with pressure sensors are installed on all four sides of the bottom loading mechanism 300. Once the operator has completed the installation of the battery pack upper cover 10, the mounting mechanisms 600 on all four sides apply pressure to the upper cover, ensuring that the pressure value on the upper cover meets quality requirements. Compared with the existing technology, the present invention can improve the safety of the equipment. Traditional manual loading requires entering the equipment to remove the upper cover. Since the equipment is provided with a wire trough and a steel beam 800, it is easy for the operator to bump into something when entering to remove the upper cover. It can also improve the mobility of the equipment. Since the upper cover loading equipment can automatically move to the upper cover removal station, the present equipment automatically removes the upper cover without stopping the conveyor line, and the production mobility is increased from the original 68% to 98%. Moreover, the path of the equipment from sucking the upper cover to moving the upper cover to the manual loading position is pre-set, and there are no foreign objects around that may collide with it, so the risk of high-rigidity sealant colliding with surrounding equipment and falling off is effectively avoided, effectively improving the quality and efficiency of the equipment. In addition, when the battery pack upper cover 10 is manually loaded on the device, the positioning structure 510 is used to cooperate with the positioning hole, i.e., the socket 11, of the battery pack upper cover 10 for positioning, to ensure that the upper cover will not be offset when loaded. After the upper cover is loaded, the operator can operate the installation mechanism 600 of the device to automatically pressurize, and display the current pressurized pressure value to ensure that the pressure meets the quality requirements, so as to improve the quality and efficiency of battery pack assembly production.

[0073] Please continue reading Figures 1 to 8 , and see Figure 9 and Figure 10The present invention also proposes a production line, which includes a crossbeam 800 and a battery pack loading device as described above. The specific structure of the battery pack loading device refers to the above embodiment. Since the present production line adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. Among them, the base 100 is slidably arranged on the crossbeam 800 along the extension direction of the crossbeam 800; along the extension direction of the crossbeam 800, loading positions and unloading positions are formed on the crossbeam 800 at intervals. The base 100 is installed with a driving assembly 900, which is used to drive the base 100 so that the top loading mechanism 200 and the bottom loading mechanism 300 drive the battery pack to move between the loading position and the unloading position.

[0074] Specifically, the drive assembly 900 includes a third drive member and a fourth drive member. The output end of the third drive member is frictionally connected to the crossbeam 800. The third drive member is mounted on the base 100 and is used to drive the base 100 so that the top loading mechanism 200 and the bottom loading mechanism 300 can move the battery pack between the loading and unloading positions. The fourth drive member has an output end that can be raised and lowered vertically. Both the loading and unloading positions on the crossbeam 800 are equipped with sockets 810. When the base 100 is in the loading or unloading position, the fourth drive member extends its output end into the socket 810 to limit the battery pack loading equipment and further improve the production accuracy of the battery pack cover.
