[0040] In order to solve this technical problem, the present invention proposes a battery pack installation device and a production line.

[0041] See also Figure 1 , Figure 2 and Figure 3 In one embodiment of the present invention, the battery pack installation device includes a base 100, a top-layer loading mechanism 200, a bottom-layer loading mechanism 300, a pick-and-place mechanism 500, and an installation mechanism 600. The top-layer loading mechanism 200 can be installed on the base 100 in a liftable manner; the bottom-layer loading mechanism 300 is located below the top-layer loading mechanism 200, and the bottom-layer loading mechanism 300 can be suspended on the top-layer loading mechanism 200 in a floating manner through a lifting mechanism 400. The lifting mechanism 400 is used to drive the bottom-layer loading mechanism 300 to rise and fall relative to the top-layer loading mechanism 200, so as to correspondingly lift the bottom-layer loading mechanism 300. The loading mechanism 300 is close to or 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; the installation mechanism 600 is installed on the top loading mechanism 200, and the installation mechanism 600 has a lifting drive 610. When the battery pack is unloaded from the bottom of the bottom loading mechanism 300, the lifting drive 610 is used to drive the bottom loading mechanism 300 to press the upper cover of the battery pack.

[0042] Specifically, in the process of installing the battery pack upper cover 10 on the battery pack lower shell, first, the top loading mechanism 200 drives the bottom 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 loading mechanism 200 and the bottom loading mechanism 300 are close to the battery pack upper cover 10 located in the upper cover suction area; then, the lifting mechanism 400 is used to extend one end of the lifting mechanism 400 connected to the bottom loading mechanism 300 downward to drive the bottom loading mechanism 300 to move downward in a direction away from the top loading mechanism 200, so that the bottom loading mechanism 300 is relatively close to the top loading mechanism 200. 00 is suspended above the battery pack upper cover 10; because the bottom loading mechanism 300 can be manually adjusted relative to the battery pack upper cover 10 when it is in the suspended state, that is, it can be adjusted in the longitudinal and lateral directions in the horizontal direction, as well as in the vertical direction, the bottom loading mechanism 300 can be tilted or horizontal relative to the battery pack upper cover 10, so that the pick-up and placement mechanism 500 installed on the bottom loading mechanism 300 can adapt to battery pack upper covers 10 of different sizes and shapes, increase the ability of the pick-up and placement mechanism 500 to adapt to different battery pack upper covers 10, and reduce the difficulty of carrying and aligning the battery pack upper cover 10, thereby improving the installation of the battery pack upper cover 10 on the battery pack. The installation accuracy and efficiency of the lower shell of the battery pack are improved; after the upper cover plate 10 of the battery pack is loaded on the bottom loading mechanism 300 by the pick-and-place mechanism 500, the lifting mechanism 400 is used to shorten the end of the lifting mechanism 400 connected to the bottom loading mechanism 300 upward, so as to drive the bottom loading mechanism 300 to move upward in the direction close to the top loading mechanism 200, so that the bottom loading mechanism 300 is pressed against the lower side of the top loading mechanism 200, so that the upper cover plate 10 of the battery pack taken by the pick-and-place mechanism 500 is loaded on the battery pack installation equipment, and transferred to the next workstation through the battery pack installation equipment; when the battery pack installation equipment drives the upper cover plate 10 of the battery pack to be transferred to the next workstation 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 lifting drive 610 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 and connected by the sealant to complete the assembly of the battery pack.

[0043] In the technical solution provided by the present invention, a bottom-layer loading mechanism 300 is used to be suspended in a floating manner on a top-layer loading mechanism 200 by a lifting mechanism 400, so that the bottom-layer loading mechanism 300 can move in multiple directions relative to the top-layer loading mechanism 200 when the pick-up and placement mechanism 500 is used to pick up and place the battery pack upper cover 10, so that the battery pack installation 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 installation accuracy and efficiency of the battery pack upper cover 10 on the battery pack lower shell. In addition, by using an installation mechanism 600 with a liftable telescopic end, after the battery pack upper cover 10 and the battery pack lower shell are aligned, the battery pack upper cover 10 is squeezed downward by the telescopic end, so that the battery pack upper cover 10 and the battery pack lower shell are pressed and connected by sealant, and the mechanized pressing action ensures uniform pressure, avoids manual operation errors, and improves the sealing quality during the battery pack assembly production process.

[0044] Please continue reading Figure 3 , and referring to 7 and 8, there are many forms of implementation of the installation mechanism 600. In the embodiment of the present invention, a plurality of pressing plates 320 arranged at intervals in the horizontal direction are installed on the bottom loading mechanism 300, and the number of the installation mechanisms 600 is multiple, and the number of the installation mechanisms 600 is consistent with the pressing plates 320 and is arranged one by one; each installation mechanism 600 includes a lifting drive 610 and a connecting seat 620, and the lifting drive 610 is installed on the top loading mechanism 200 through the connecting seat 620, and the output end of the lifting drive 610 forms a telescopic end. Specifically, a plurality of pressing plates 320 arranged at intervals are installed on the bottom loading mechanism 300, so that during the installation process of the battery pack upper cover 10, multiple areas of the upper cover can be pressed, and multiple pressing plates 320 ensure that the pressure distribution of the upper cover is uniform during installation, and the uniform pressure distribution ensures that the sealant can be uniformly compressed, thereby improving the sealing effect, avoiding water leakage and air leakage caused by poor sealing, avoiding pressure concentration at a single point or a small number of points, preventing deformation or damage of the upper cover, and 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.

[0045] Each installation mechanism 600 controls a pressing plate 320 individually, and can accurately control 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 installation mechanism 600, it can be flexibly adjusted according to different installation requirements. For example, different pressure values ​​can be set according to different areas of the battery pack to further optimize the installation effect. In addition, during the installation of the upper cover plate, segmented pressure can be achieved through the installation mechanism 600, that is, pressure can be gradually applied to different areas as needed, avoiding excessive stress caused by one-time pressure and improving the stability and reliability of the installation.

[0046] 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 a pneumatic cylinder with a movable end in the prior art.

[0047] Please continue to refer to Figure 3 , Figure 7 and Figure 8 More specifically, in an embodiment of the present invention, the battery pack installation device further includes a plurality of buffer blocks 330, which are installed at intervals along the horizontal direction at the bottom of the bottom mounting mechanism 300, and the plurality of buffer blocks 330 extend vertically. The plurality of buffer blocks 330 arranged at intervals can evenly distribute the pressure, and 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, during the installation of the upper cover plate, thereby preventing direct and excessive stress concentration on the upper cover plate 10 of the battery pack, reducing the deformation and damage risks of the upper cover plate, and preventing the upper cover plate and the bottom mounting mechanism 300 from being adversely affected by vibration, thereby improving the stability of the overall installation process.

[0048] As an optional implementation of this embodiment, a gap is left between two adjacent buffer blocks 330, and 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.

[0049] Please continue to refer to Figure 3In the embodiment of the present invention, there are many forms of implementation of the lifting mechanism 400. The lifting mechanism 400 includes a first driving member 410, a steering mechanism 420 and a lifting 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 fixing seat 411 and an output shaft 412. The connecting end 431 of the lifting rope 430 is connected to the fixing seat 411, and the free end 432 of the lifting rope 430 is connected to the bottom-level carrying mechanism 300 via the steering mechanism 420. The first driving member 410 is used to drive the lifting rope 430 in the horizontal direction through the output shaft 412, so that the lifting rope 430 drives the bottom-level carrying mechanism 300 to rise and fall after being turned by the steering mechanism 420.

[0050] The steering mechanism 420 is used to redirect the horizontal movement of the pulling rope 430 into vertical movement.

[0051] The first driving member 410 is hinged to the top-level loading mechanism 200 through a 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 loading mechanism 300 is close to the top-level loading mechanism 200, the bottom-level loading mechanism 300 can be more closely against the top-level loading mechanism 200, thereby reducing the shaking of the battery pack cover carried on the bottom-level loading mechanism 300 during transportation, thereby improving the production safety of the battery pack.

[0052] As a flexible connector, the pulling rope 430 can adapt to different spatial layouts under the action of the steering mechanism 420, increasing the flexibility and adaptability of the equipment, allowing the bottom loading mechanism 300 to float relative to the top loading mechanism 200, facilitating manual position adjustment, and adapting to battery pack upper covers 10 of different sizes and shapes.

[0053] It should be noted that the pulling rope 430 can be a steel wire rope in the prior art or other ropes having both strength and toughness.

[0054] Please continue to refer to Figure 3 Specifically, in an embodiment of the present invention, the steering mechanism 420 includes two fixed pulleys 421, and the two fixed pulleys 421 are both 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.

[0055] 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 the lifting efficiency, and ensures that the lifting rope 430 will not get stuck or worn due to the change of direction during the movement, thereby improving the reliability and stability of the equipment, so that the horizontally driven lifting rope 430 can realize the vertical force transmission through the turning of the fixed pulley 421, and the gap serves as the passage 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 operation stability, and ensuring that the lifting rope 430 passes smoothly between the two fixed pulleys 421 to be connected to the underlying carrying mechanism 300, thereby accurately realizing the force transmission and the turning of movement.

[0056] Please continue reading Figure 3 More specifically, in an embodiment of the present invention, 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 is connected to the bottom-layer carrying mechanism 300 through a seam around the movable pulley 423, and the lifting rope 430 is slidably matched with the movable pulley 423, and the first driving member 410 is used to drive the pulley seat 422 and the movable pulley 423 in a horizontal direction through the output shaft 412, so that the lifting rope 430 drives the bottom-layer carrying mechanism 300 to rise and fall after being turned by the movable pulley 423.

[0057] 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 in the horizontal direction 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, and provide 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.

[0058] 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 a horizontal direction, and the pulley seat 422 is slidably installed on the guide rail 220 in a horizontal direction.

[0059] The guide rail 220 extends in the horizontal direction, providing a stable and precise sliding path for the pulley seat 422, ensuring that the pulley seat 422 will not deviate or shake during the sliding process, so that the movement of the bottom mounting mechanism 300 carrying the battery pack cover is more precise and controllable. In addition, the guide rail 220 also reduces the energy loss of the pulley seat 422 due to friction or resistance, thereby improving work efficiency.

[0060] 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 on the bottom of the bottom loading mechanism 300 or unload it from the bottom of the bottom loading mechanism 300.

[0061] The positioning structure 510 is used to accurately position the battery pack to ensure that the battery pack is accurately positioned during the loading process, so as to reduce installation errors caused by position deviation, 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 operation steps, improving the operation efficiency, and shortening the installation time of the battery pack.

[0062] Please continue reading Figure 4 and Figure 5 Specifically, in an embodiment of the present invention, a socket 11 is formed on the top of the battery pack; a positioning structure 510 is arranged corresponding to the socket 11; the positioning structure 510 includes a support 511, a latch 512 and a limit plate 513, the support 511 is installed on the bottom mounting mechanism 300, the limit plate 513 is movably installed on the support 511 in the horizontal direction, the latch 512 is slidably installed on the limit plate 513 in the vertical direction, and the latch 512 is used to be inserted into the socket 11 to position the battery pack.

[0063] A portion of the limit plate 513 is inserted into the support 511 through a ball bearing, so that the pin 512 installed on the limit plate 513 can be adjusted in position on the horizontal plane to adapt to the sockets 11 at different positions on the top of the battery pack cover 10 in the horizontal direction. The pin 512 is slidably installed on the limit plate 513 in the vertical direction, so that the height of the pin 512 can be adjusted in the vertical direction to ensure that the pin 512 can be accurately inserted into the socket 11. No matter how the height of the socket 11 changes, accurate alignment can be achieved, which improves the flexibility and adaptability of the device and the battery pack cover 10 when aligning. In addition, the pin 512 can be accurately adjusted in two dimensions, so as to achieve accurate alignment of the socket 11, significantly improve the positioning accuracy of the battery pack cover 10, and reduce installation errors.

[0064] In addition, the latch 512 is slidably installed on the limit plate 513 along the vertical direction. During the plug-in process, the latch 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 latch 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.

[0065] As an optional implementation manner of the present embodiment, a latch 512 and a limit plate 513 form a latch 512 assembly, and the two latch 512 assemblies are relatively arranged along the diagonal of the underlying mounting mechanism 300 to ensure that at least two of the four corner points of the battery pack upper cover 10 on the underlying 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.

[0066] 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 clamp 700, which is hinged to the outer edge of the top loading mechanism 200 and can rotate between a clamping position or a release position relative to the top loading mechanism 200 to clamp or release the battery pack accordingly.

[0067] Specifically, during the battery pack loading process, when the battery pack is loaded on the bottom of the bottom loading mechanism 300, the clamp 700 rotates to the clamping position to firmly clamp the battery pack. The clamp 700 provides additional fixing force for the upper cover of the battery pack 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 clamp 700 can rotate to a loose position to release the upper cover 10 of the battery pack when the battery pack is unloaded. When the clamp 700 clamps the upper cover 10 of the battery pack, it not only provides additional positioning for the loading process of the upper cover 10 of the battery pack, 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.

[0068] As an optional implementation of this embodiment, one end of the clamping jaw 700 is connected to the output end of the second driving member, the fixed end of the second driving member is hinged to the top frame 210, and the second driving member is used to drive the clamping jaw 700 to rotate between the clamping position and the 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 a pneumatic cylinder with a movable end in the prior art.

[0069] As another optional implementation of this embodiment, in order to prevent damage to the upper cover plate 10 of the battery pack, a buffer pad is provided on the clamping jaw 700.

[0070] As a specific embodiment of the present invention, 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 taking out the upper cover, 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 taking out the upper cover, the high-rigidity sealant at its edge is easy to collide with surrounding objects, causing the sealant to fall off. When the upper cover with the sealant falling off is loaded on 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 scraped off 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.

[0071] The battery pack installation device takes and places the upper cover of the battery pack 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 picking and placing mechanism 500 installed on the bottom loading mechanism 300, i.e., the bottom frame 310. When the battery pack installation device reaches the loading position of the upper cover plate 10 of the battery pack, the top loading mechanism 200 drives the bottom loading mechanism 300 to descend to the initial adjustment position toward the direction close to the upper cover plate 10 of the battery pack. Then, the bottom loading mechanism 300 is lowered by the lifting mechanism 400, so that the bottom loading mechanism 300 is separated from the top loading mechanism 200 and suspended above the battery pack upper cover 10. The four sides of the bottom loading mechanism 300 are connected to the top loading mechanism 200 through the steel wire ropes in the lifting mechanism 400, and there are anti-loosening support protections between the multiple steel wire ropes. The operator can quickly perform the positioning operation of the battery pack upper cover 10 and the battery pack lower shell, and accurately position them through the positioning structure 510, eliminating an operation supervisor. In addition, installation mechanisms 600 with pressure sensors are installed around the bottom loading mechanism 300. When the operator completes the installation of the battery pack upper cover 10, the upper cover is pressurized through the installation mechanisms 600 around the four sides, so that the pressure value of the upper cover meets the quality requirements. Compared with the prior art, the present invention can improve the safety of the equipment. Traditional manual loading requires entering the equipment to take out 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 or otherwise cause safety accidents when entering to take out 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 takes out the upper cover without stopping the conveyor line, and the production mobility is increased from the original 68% to 98%. Moreover, the path that the present equipment takes from sucking up the upper cover to moving the upper cover to the manual loading position is set, and there are no foreign objects in the surrounding area 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 upper cover plate 10 of the battery pack 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 upper cover plate 10 of the battery pack for positioning, to ensure that the upper cover plate will not be offset when loaded. After the upper cover plate 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.

[0072] Please continue reading Figures 1 to 8 , and see Fig. 9 and Fig.10The present invention also proposes a production line, which includes a beam 800 and a battery pack installation device as described above. The specific structure of the battery pack installation 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 by the technical solutions of the above embodiments, which will not be repeated here. Among them, the base 100 is slidably arranged on the beam 800 along the extension direction of the beam 800; along the extension direction of the beam 800, a loading position and an unloading position are formed on the beam 800 at intervals, and 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.

[0073] Specifically, the driving assembly 900 includes a third driving member and a fourth driving member. The output end of the third driving member is frictionally connected to the crossbeam 800. The third driving member is installed on the base 100. The third driving member 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. The fourth driving member has an output end that can be raised and lowered vertically. The loading position and the unloading position on the crossbeam 800 are both installed with a socket 810. The fourth driving member is used to extend its output end into the socket 810 when the base 100 is in the loading position or the unloading position, so as to limit the battery pack installation equipment and further improve the production operation accuracy of the battery pack cover.
