Description

Technical Field

[0001] The present invention relates to battery disassembly equipment, in particular to an automatic transmission and separation line for battery packs. Background Art

[0002] The common structure of a battery pack is that the base and the cover are spliced up and down to form a closed box space and the battery is locked in the middle of the box. During the processing of the battery pack, due to its heavy weight, it is usually placed on a conveyor for transportation. Multiple workstations are set up on the conveyor. Different battery packs are conveyed to the workstations via the conveyor for manual disassembly, and the battery packs are disassembled into battery modules or single cells.

[0003] The transmission disk on the traditional work station adopts a method in which the bottom and side wheels passively drive the entire transmission disk to move. However, due to the heavy weight of the entire battery pack and the transmission disk, the transmission disk on the existing work station adopts an active power method, and the transmission disk is driven to move by the automatic transmission structure so that the transmission disk reaches the specified position. However, in the process of active transmission of the transmission disk, in order to correctly guide it, other guide structures need to be set at the bottom, such as guide rails and guide wheels. Although this structure can be used for guidance, the transmission disk needs to actively brake during the disassembly of the battery pack. If the guide rail and guide wheel structure is set internally, it is difficult to set a brake structure. If it only relies on the brake of the power structure itself, when multiple workers operate on the transmission disk, due to changes in the center of gravity and the operation of the disassembly equipment, the entire transmission disk is prone to vibration or position change, which in turn affects the power structure, making it difficult for the transmission disk to move smoothly to the correct position after long-term use, and it is prone to jamming, which in turn affects the disassembly progress of the battery pack.

[0004] Therefore, this case aims to provide an automated battery pack transmission and distribution line, which can not only ensure the stable movement of the transmission tray used to transmit batteries, but also ensure the stable braking coordination of the power structure and the transmission tray when disassembling the battery pack, thereby ensuring the stable use of the transmission tray in two states. Summary of the Invention

[0005] The present invention provides an automated battery pack transmission and distribution line, which can effectively solve the above problems.

[0006] The present invention is achieved in that: An automated battery pack conveying and distributing line comprises: a main conveying frame, with a plurality of disassembly stations disposed laterally thereon, each of which is movably provided with a movable plate, wherein the main conveying frame conveys the plurality of battery packs to the disassembly stations respectively and moves the battery packs to the lower end of a disassembly tool via the movable plate; The lower power guide structure, the middle part of the lower end of the movable plate is a mating surface, the lower power guide structure includes a middle positioning frame arranged at the bottom of the disassembly station, two groups of hydraulic cylinders are arranged on the middle positioning frame, a balancing frame is arranged on the hydraulic cylinder, and two groups of middle power wheel groups are arranged in the middle of the balancing frame, and linkage parts are respectively provided at the front and rear ends of the middle power wheel group, and the ends of the two linkage parts are connected to two clamping guide wheels. When the hydraulic cylinder moves upward, the middle power wheel group moves upward and engages with the mating surface, and the two groups of clamping guide wheels slide outward and fit into the lower end of the mating surface. When the hydraulic cylinder moves downward, the middle power wheel group moves downward and disengages from the mating surface, and the two groups of clamping guide wheels slide inward and engage with the mating surface. The inner guide wheel auxiliary structure includes a guide frame arranged at the rear end of the clamping guide wheel, the guide frame is fixedly connected to the inner side of the disassembly station, and a side extension is axially provided at the front end of the clamping guide wheel. The end of the side extension away from the clamping guide wheel is hinged on the inner wall of the disassembly station.

[0007] As a further improvement, the mating surface includes a rough contact surface arranged at the center of the bottom of the movable disk, and guide contact surfaces are respectively arranged on both sides of the rough contact surface.

[0008] As a further improvement, the balancing platform includes a mounting plate connected to the hydraulic cylinder, and two groups of auxiliary brackets are provided on the upper end of the mounting plate, and the tops of the auxiliary brackets extend to the clamping guide wheels.

[0009] As a further improvement, the auxiliary bracket includes a lower movable button mounted on the mounting plate, the top of the lower movable button is connected to a hydraulic auxiliary telescopic rod, the top of the hydraulic auxiliary telescopic rod is connected to an upper movable button, and the upper movable button is mounted on the clamping guide wheel.

[0010] As a further improvement, the central power wheel group includes a central motor locked on a balancing frame, an upper fixing frame is provided on the top of the central motor, a central guide wheel is locked on the top of the upper fixing frame, the central axis of the central guide wheel is connected to the central motor by a belt, and the central guide wheel is movably matched with the rough contact surface.

[0011] As a further improvement, the linkage member includes a lower ring sleeved on the central axis of the middle guide wheel, an upper ring sleeved on the central axis of the clamping guide wheel, and the upper ring and the lower ring are connected by a pull plate.

[0012] As a further improvement, the clamping guide wheel includes a side guide gear that movably cooperates with the guide contact surface, the rear end of the side guide gear central axis is provided with a guide column head, and the front end of the side guide gear central axis is connected to a connecting column head.

[0013] As a further improvement, the guide frame includes a gusset plate arranged on the inner side of the disassembly station, the inner side of the gusset plate is provided with a guide groove, and the guide column head is movably connected in the guide groove.

[0014] As a further improvement, the side extension member includes an electric push rod hingedly mounted on the inner wall of the disassembly station, a hinge is connected to the output end of the electric push rod, and the connecting column head is hinged in the hinge.

[0015] The beneficial effects of the present invention are: The active braking state of the transmission disk in the prior art relies on the active braking of the power mechanism. When multiple workers operate on the transmission disk, the change in the center of gravity and the operation of the disassembly equipment make the entire transmission disk easily vibrate or change position, thereby hindering the movement of the transmission disk. Therefore, the present invention uses a lower power guide structure arranged in the same direction as the moving direction of the mobile disk. When the mobile disk needs to move, the hydraulic cylinder pushes up to move the middle power wheel group upward and engages with the mating surface, so that the middle power wheel group acts as the active power to drive the mobile disk to move, and the clamping guide wheel acts as a guide as part of the guide rail, so that the movement of the mobile disk can be more accurate, and a stable trajectory can always be maintained even in reciprocating motion. When the mobile disk needs to be fixed, the middle power wheel group can be disengaged from the mobile disk, and the clamping guide wheel can be tightly pressed against the lower end of the mobile disk, so that the mobile disk can not only maintain stability during movement, but also ensure stability when the battery pack is disassembled, so that the heavy mobile disk can remain smooth during movement.

[0016] In the process of the middle power wheel group and the clamping guide wheel cooperating with the mating surface, due to their different functions, the required mating surfaces are also different. Therefore, the mating surface of the present invention is divided into a rough contact surface and a guide contact surface, which can produce different effects. The middle power wheel group has a stronger meshing effect when driving the movable disk to move, and only requires contact force when guiding.

[0017] In order to ensure that the clamping guide wheel has a supporting effect no matter what position it is in, the present invention provides an auxiliary bracket at the lower end of the clamping guide wheel. Through the hydraulically assisted telescopic rods movably installed on both sides, the clamping guide wheel can be supported by the hydraulically assisted telescopic rods whether in the supporting state or the guiding state. The hydraulically assisted telescopic rods will adjust their own position as the position of the clamping guide wheel changes, thereby improving the practicality of the present invention.

[0018] The entire central power wheel assembly not only serves as the main driving force, but also serves as the power source for the clamping guide wheel when it moves. Therefore, the central power wheel assembly of the present invention is first connected to the balance frame to provide a basis for the installation of the central motor, so that the upper and lower positions can be switched, thereby changing the lateral position of the clamping guide wheel. Secondly, the central guide wheel connected to the central motor cooperates with the rough contact surface to provide lateral power for the moving disk, thereby realizing multiple functions through one power structure.

[0019] The linkage part serves as a connecting mechanism connecting the middle power wheel group and the clamping guide wheel. It does not have active power itself. It mainly plays the role of traction and guidance. Specifically, it cooperates with the middle power wheel group and the clamping guide wheel through the lower ring and the upper ring respectively. When the middle power wheel group moves, the clamping guide wheel will be pulled through the pull plate to achieve stable cooperation between the two.

[0020] The clamping guide wheel plays a driven role, but it needs to cooperate with multiple structures so that it can receive correct guidance and support effects. Therefore, the front and rear ends of the clamping guide wheel of the present invention are provided with column head structures, so that the entire trajectory of the side guide gear can be within the set range, and the displacement stability is higher.

[0021] The clamping guide wheel needs to play the role of guiding and clamping at the same time, and its running trajectory is particularly important, otherwise the clamping guide wheel will no longer be able to contact the mating surface of the movable disk after resetting. Therefore, the present invention provides an inner guide wheel auxiliary structure based on the lower power guide structure, so that the inner guide wheel auxiliary structure is pulled and reset by the guide frame at the rear end and the side extension piece at the front end, so that it can follow the planned trajectory when moving laterally and when moving to the middle, and there is a certain supporting internal pressure effect when supporting the movable disk at the inner position, and the stability of the movable disk is not changed by the change of the center of gravity during disassembly.

[0022] The guide groove in the guide frame has a special track, which allows the column head of the side guide gear to move directly in the guide groove, thereby regulating its own movement path.

[0023] However, in fact, the main power of the side guide gear still depends on the side extension member. The electric push rod on the side extension member can assist the linkage member to drive the side extension member to push out or pull back the clamping guide wheel, so that the clamping guide wheel can move accurately along the track and provide sufficient guiding force from the side and bottom positions.

In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0036] Reference Figures 1 to 8As shown, an automatic transmission and distribution line for battery packs comprises: a main transmission frame 10, a plurality of disassembly stations 20 are arranged on the side of the main transmission frame 10, a movable plate 30 is movably arranged on the disassembly station 20, the main transmission frame 10 transfers a plurality of battery packs to the disassembly station 20 respectively and moves them to the lower end of the disassembly tool through the movable plate 30; a lower power guide structure 40, the middle part of the lower end of the movable plate 30 is a mating surface 31, the lower power guide structure 40 comprises a middle positioning frame 41 arranged at the bottom inside the disassembly station 20, two groups of hydraulic cylinders 42 are arranged on the middle positioning frame 41, a balancing frame 43 is arranged on the hydraulic cylinder 42, two groups of middle power wheel groups 44 are arranged in the middle of the balancing frame 43, and the front and rear ends of the middle power wheel group 44 are respectively provided with Linkage 45, the ends of the two linkages 45 are connected to the two clamping guide wheels 46. When the hydraulic cylinder 42 moves upward, the middle power wheel group 44 moves upward and engages with the mating surface 31, and the two groups of clamping guide wheels 46 slide outward and fit against the lower end of the mating surface 31. When the hydraulic cylinder 42 moves downward, the middle power wheel group 44 moves downward and disengages from the mating surface 31, and the two groups of clamping guide wheels 46 slide inward and engage with the mating surface 31; the inner guide wheel auxiliary structure 50 comprises a guide frame 51 arranged at the rear end of the clamping guide wheel 46, the guide frame 51 is fixed to the inner side of the disassembly station 20, and a side extension 52 is axially provided at the front end of the clamping guide wheel 46, and the end of the side extension 52 away from the clamping guide wheel 46 is hinged to the inner wall of the disassembly station 20.

[0037] from Figure 1 It can be seen that many disassembly stations 20 are set on the side of the main transmission frame 10, and two disassembly stations 20 are set opposite each other, and a horizontal conveyor belt is also set between the two opposite disassembly stations 20, so as to choose the direction to move the battery pack.

[0038] In this embodiment, only four disassembly stations 20 are provided. However, a main transmission frame 10 on an actual production line is equipped with a total of 10 disassembly stations 20 .

[0039] The active braking state of the transmission disc in the prior art relies on the active braking of the power mechanism. When multiple workers operate on the transmission disc, the change in the center of gravity and the operation of disassembling the equipment make the entire transmission disc easily vibrate or change position, thereby hindering the movement of the transmission disc. Therefore, in this embodiment, a lower power guide structure 40 is arranged in the same direction as the moving direction of the moving disc 30. When the moving disc 30 needs to move, the hydraulic cylinder 42 pushes up to allow the middle power wheel group 44 to move upward and engage with the mating surface 31, so that the middle power wheel group 44 acts as the active power to drive the moving disc 30. 0 action, and the clamping guide wheel 46 plays a guiding role as part of the guide rail, so that the movement of the movable plate 30 can be more accurate, and a stable trajectory can always be maintained even in reciprocating motion. When the movable plate 30 needs to be fixed, the middle power wheel group 44 can be separated from the movable plate 30, and the clamping guide wheel 46 can be tightly pressed against the lower end of the movable plate 30, so that the movable plate 30 can not only maintain stability during movement, but also ensure stability when the battery pack is removed, so that the heavy movable plate 30 can maintain a smooth state when moving.

[0040] In the process of the middle power wheel group 44 and the clamping guide wheel 46 cooperating with the mating surface 31, due to their different functions, the required mating surfaces are also different. Therefore, the mating surface 31 of this embodiment includes a rough contact surface 311 arranged at the bottom center of the movable disk 30, and guide contact surfaces 312 are respectively provided on both sides of the rough contact surface 311, dividing the mating surface 31 into the rough contact surface 311 and the guide contact surface 312, thereby producing different effects. The middle power wheel group 44 has a stronger meshing effect when driving the movable disk 30 to move, and only requires contact force when guiding.

[0041] In order to ensure that the clamping guide wheel 46 has a supporting effect at any position, the balancing stand 43 of this embodiment includes a mounting plate 431 connected to the hydraulic cylinder 42, and two sets of auxiliary brackets 432 are provided on the upper end of the mounting plate 431. The top of the auxiliary bracket 432 extends to the clamping guide wheel 46. By providing an auxiliary bracket 432 at the lower end of the clamping guide wheel 46, the auxiliary bracket 432 includes a lower movable button 4321 mounted on the mounting plate 431, and the top of the lower movable button 4321 is The top of the hydraulically assisted telescopic rod 4322 is connected to the upper movable button 4323, and the upper movable button 4323 is installed on the clamping guide wheel 46. The hydraulically assisted telescopic rod 4322 is movably installed on both sides, so that the clamping guide wheel 46 can be supported by the hydraulically assisted telescopic rod 4322 whether it is in a supporting state or a guiding state. The hydraulically assisted telescopic rod 4322 will adjust its own position as the position of the clamping guide wheel 46 changes, thereby improving the practicality of the present invention.

[0042] The entire middle power wheel group 44 not only plays the role of the main power, but also serves as the power source for the clamping guide wheel 46 when it moves. Therefore, the middle power wheel group 44 of this embodiment includes a middle motor 441 locked on the balance frame 43, and an upper fixed frame 442 is provided on the top of the middle motor 441. A middle guide wheel 443 is locked on the top of the upper fixed frame 442. The middle axis of the middle guide wheel 443 is connected to the middle motor 441 by a belt, and the middle guide wheel 443 is movably matched with the rough contact surface 311. The middle power wheel group 44 is first connected to the balance frame 43 to provide a basis for the installation of the middle motor 441, so that the upper and lower positions can be switched, thereby changing the lateral position of the clamping guide wheel 46. Moreover, the middle guide wheel 443 connected to the middle motor 441 cooperates with the rough contact surface 311 to provide lateral power for the moving disk 30, thereby realizing multiple functions through one power structure.

[0043] The linkage member 45 serves as a connecting mechanism connecting the middle power wheel group 44 and the clamping guide wheel 46. It does not have active power itself, and its main function is to traction and guidance. Specifically, the linkage member 45 includes a lower ring 451 sleeved on the central axis of the middle guide wheel 443, and an upper ring 452 sleeved on the central axis of the clamping guide wheel 46. The upper ring 452 and the lower ring 451 are connected by a pull plate 453, and the lower ring 451 and the upper ring 452 are respectively coordinated with the middle power wheel group 44 and the clamping guide wheel 46. When the middle power wheel group 44 moves, the clamping guide wheel 46 will be pulled to move through the pull plate 453 to achieve stable coordination between the two.

[0044] The clamping guide wheel 46 plays a driven role, but it needs to cooperate with multiple structures so that it can be correctly guided and supported. Therefore, the clamping guide wheel 46 of this embodiment includes a side guide gear 461 that movably cooperates with the guide contact surface 312. The rear end of the central axis of the side guide gear 461 is provided with a guide column head 462, and the front end of the central axis of the side guide gear 461 is connected with a connecting column head 463. The front and rear ends of the clamping guide wheel 46 are both provided with column head structures, so that the entire trajectory of the side guide gear 461 can be within the set range, and the displacement stability is higher.

[0045] The clamping guide wheel 46 needs to play the role of guiding and clamping at the same time, and its running trajectory is particularly important, otherwise the clamping guide wheel 46 will no longer be able to contact the mating surface 31 of the movable disk 30 after resetting. Therefore, this embodiment provides an inner guide wheel auxiliary structure 50 on the basis of the lower power guide structure 40, so that the inner guide wheel auxiliary structure 50 is pulled and reset by the guide frame 51 at the rear end and the side extension 52 at the front end, so that it can follow the planned trajectory when moving laterally and when moving to the middle, and there is a certain supporting internal pressure effect when supporting the movable disk 30 at the inner position, and the stability of the movable disk 30 is not changed by the change of the center of gravity during disassembly.

[0046] The guide groove 512 in the guide frame 51 has a special trajectory. Specifically, the guide frame 51 includes a buckle plate 511 arranged on the inner side of the disassembly station 20. The inner side of the buckle plate 511 is provided with a guide groove 512. The guide column head 462 is movably connected in the guide groove 512, so that the column head of the side guide gear 461 can directly move in the guide groove 512, thereby regulating its own moving path.

[0047] However, in fact, the main power of the side guide gear 461 still depends on the side extension member 52, which includes an electric push rod 521 hingedly installed on the inner wall of the disassembly station 20, and a hinge 522 is connected to the output end of the electric push rod 521. The connecting column 463 is hinged in the hinge 522. Through the electric push rod 521 on the side extension member 52, the linkage member 45 can assist the side extension member 52 to push out or pull back the clamping guide wheel 46, so that the clamping guide wheel 46 can move accurately along the track and provide sufficient guiding force from the side and bottom positions.

[0048] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
