Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a battery module flipping device and a battery production line. Background Technology

[0002] After the bottom liquid cooling plate is installed in the upward moving process, the battery module needs to be rotated 180° so that the terminals face upward to facilitate the subsequent welding of the busbar. Therefore, a module rotation device is needed to rotate the module from the terminal-down position to the terminal-up position by 180°.

[0003] The existing technical solution involves setting up a gripping mechanism above the battery module to remove the battery module and its tray from the previous process tray. The module is then moved laterally to a flipping mechanism, where two flipping mechanisms are used. After the flipping mechanism flips the battery module and its tray together 180°, the gripping mechanism places them together into the next process tray. Finally, the battery module tray is picked up separately and placed back into the previous process tray.

[0004] The shortcomings of existing technologies are as follows: During the flipping process, the battery module was damaged due to the asynchronous movement of the flipping mechanisms at both ends. There is a risk that the pallet may slip during the lifting and lowering process due to misoperation, posing a safety hazard. Because the battery module needs to be placed on two different trays before and after flipping, there is a problem that the battery module cannot be successfully placed into the subsequent tray after flipping. The complex flipping process leads to a complex structure for the flipping equipment; Increased land area; The route layout is unreasonable.

[0005] In summary, existing technical solutions significantly increase the time required for battery module flipping and pose a risk of battery module falling and being damaged during handling and flipping. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention discloses a battery module flipping device and a battery production line.

[0007] The technical solution adopted in this invention is as follows: A battery module flipping device, comprising: frame; A conveying transition module, located at the bottom of the frame, is used for conveying pallets.

One side of the slide plate is provided with a sliding plate bearing, and the other side of the slide plate is provided with at least one guide rod fitted with a reset element. The ends of the guide rod and the reset element abut against the baffle. The push block has a sliding surface that mates with the sliding plate bearing.

One side of the connecting block is provided with a lifting bearing, and the lifting drive source drives the connecting block to rise and fall. A flipping module, located in the middle of the frame, is used to flip the battery module; A lifting module is located on both sides of the frame and is used to reciprocate the conveying transition module between the bottom of the frame and the tilting module. The lifting module includes a lifting drive source, a first drive shaft connected to the output end of the lifting drive source, and two sets of lifting screws connected through the first drive shaft. The conveying transition module is connected to the movable part of the lifting screws. A synchronizer is connected below each of the two sets of lifting screws. The two synchronizers are connected by the first drive shaft and contain a gear pair. The current conveyor line delivers the front pallet and the battery module it carries to the conveyor transition line. The limiting mechanism blocks the front pallet, and the lifting mechanism fixes the position of the front pallet and disengages it from the conveyor transition line. The lifting module raises the conveyor transition line, the front pallet, and the battery module together to the height of the flipping mechanism. The clamping mechanism of the flipping mechanism holds the battery module. The lifting module lowers the conveyor transition line and the empty front pallet to the pallet return height. At the same time, the flipping mechanism drives the battery module to flip. The rear conveyor line delivers an empty rear pallet to the conveyor transition line. The limiting mechanism blocks the rear pallet, and the lifting mechanism fixes the position of the rear pallet and separates it from the conveyor transition line. The lifting module raises the conveyor transition line and the rear pallet to the height of the flipping mechanism to receive the flipped battery module. The flipping mechanism releases the battery module, and the lifting module lowers the conveyor transition line, the rear pallet, and the battery module together to the height of the rear conveyor line. The rear pallet is then conveyed out of the battery module flipping device by the conveyor transition line.

[0008] In one embodiment of the present invention, the conveying transition line includes a conveying frame and a conveying drive source disposed on one side of the conveying frame. The conveying frame is provided with a conveyor belt, and the conveying drive source transmits power to the conveyor belt through a transmission assembly.

[0011] In one embodiment of the present invention, the flipping mechanism includes a flipping frame and clamping mechanisms disposed on both sides of the flipping frame, wherein the clamping mechanisms clamp the battery module in at least one direction.

[0012] In one embodiment of the present invention, the clamping mechanism includes a first clamping drive source and a first clamping plate connected to the actuating end of the first clamping drive source, wherein the first clamping drive source pushes the first clamping plate toward the battery module along a first direction.

[0013] In one embodiment of the present invention, the clamping mechanism includes a second clamping drive source and a second clamping plate connected to the working end of the second clamping drive source, wherein the second clamping drive source pushes the second clamping plate toward the battery module in a second direction.

[0014] In one embodiment of the present invention, the frame includes a first frame, a second frame, and a lifting frame. The first frame and the second frame are arranged in parallel, and a plurality of connecting rods are provided between the first frame and the second frame. The lifting frame is located between the first frames and between the second frames.

[0015] The present invention also provides a battery production line, including the battery module flipping equipment as described above.

[0016] The technical solution of the present invention has the following advantages over the prior art: The battery module flipping device of this invention comprises the following steps: The front conveyor line delivers a front tray and the battery modules it carries to a conveyor transition line. A limiting mechanism blocks the front tray, and a lifting mechanism fixes the tray's position and detaches it from the conveyor transition line. A lifting module raises the tray and battery modules together to the height of the flipping mechanism, where a clamping mechanism holds the battery modules. The lifting module lowers the empty tray to its return height, and simultaneously, the flipping mechanism flips the battery modules. The rear conveyor line delivers an empty rear tray to the conveyor transition line. A limiting mechanism blocks the tray, and a lifting mechanism fixes the tray's position and detaches it from the conveyor transition line. The lifting module raises the tray to the height of the flipping mechanism to receive the flipped battery modules. The flipping mechanism releases the battery modules, and the lifting module lowers the rear tray and battery modules together to the height of the conveyor transition line. The tray is then conveyed out of the battery module flipping device by the conveyor transition line. This design simplifies the structure of the battery module flipping device, making its operation simple, its debugging convenient, its cycle time short, and its operation unaffected by the product components. It also reduces the footprint and lowers the equipment cost. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0028] The foregoing and other technical contents, features, and effects of the present invention will be clearly presented in the following detailed description of the embodiments with reference to the accompanying drawings. The directional terms mentioned in the following embodiments, such as up, down, left, right, front, or back, are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting the present invention. Furthermore, in all embodiments, the same reference numerals denote the same elements.

[0029] Practical use revealed the following shortcomings of the existing technology: 1. Complex structure: The complex mechanism increases the difficulty of assembly and debugging, making the actions cumbersome and posing a risk of battery modules falling during transport. 2. Long cycle time: The process involves numerous actions, and since the battery module and pallet are picked up together, the pallet must be returned to its original position after the battery module is flipped, increasing the operation time. 3. Potential for product damage: The two flipping mechanisms achieve synchronous flipping via a drive shaft and two synchronous belts. However, due to the elastic deformation of the synchronous belts, slight asynchrony may occur between the two mechanisms during the actual flipping process. This slight asynchrony can ultimately affect the battery module, causing deformation and potentially damaging it. 4. Large footprint: Due to the inherent limitations of the operational logic, the front and rear pallet conveyor lines need to be staggered, increasing the overall footprint of the line.

[0030] To address the aforementioned problems, this invention provides a battery module flipping device and a battery production line.

[0031] Combination Figures 1 to 5 A battery module flipping device, comprising: 100 racks; A conveying transition module, located at the bottom of the frame 100, is used to convey the pallet 800. The conveying transition module includes a conveying transition line 200 and positioning modules located on both sides of the conveying transition line 200. The positioning modules include a limiting mechanism 600 and a lifting mechanism 700. The limiting mechanism 600 includes a base 603, a pallet stop pin 602 perpendicularly passing through the base 603, a track plate 604 located within the base 603, a sliding plate 605 fixedly connected to the track plate 604 and slidably connected to the bottom of the base 603, a push block 601 fixed to the frame 100, and a baffle 608 fixed to the base 603. The pallet stop pin 600... One end of the slide plate 604 is provided with a reset bearing, and the track plate 604 is provided with a reset groove through which the reset bearing passes; one side of the slide plate 605 is provided with a sliding plate bearing 611, and the other side of the slide plate 605 is provided with at least one guide rod 606 on which a reset element 607 is sleeved. The end of the guide rod 606 and the end of the reset element 607 abut against the baffle 608. The push block 601 has a sliding surface that cooperates with the sliding plate bearing 611; the lifting mechanism 700 includes a lifting drive source and a connecting block 701 connected to the lifting drive source, and one side of the connecting block 701 is provided with a lifting bearing 702. The lifting drive source drives the connecting block 701 to rise and fall. A flip module, located in the middle of the frame 100, is used to flip the battery module 900; The lifting module is located on both sides of the frame 100 and is used to move the conveying transition module back and forth between the bottom of the frame 100 and the flipping module.

[0032] In this embodiment, as Figure 2 As shown, the frame 100 includes a first frame 102, a second frame 103 and a lifting frame 104. The first frame 102 and the second frame 103 are arranged in parallel, and a plurality of connecting rods are provided between the first frame 102 and the second frame 103. The lifting frame 104 is located between the first frames 102 and between the second frames 103.

[0033] Specifically, the first frame 102 includes two sets of discontinuously arranged first support units, the two sets of first support units being on the same horizontal plane; each first support unit has two opposing first transverse supports and a second transverse support connecting the two first transverse supports.

[0034] Similarly, the second frame 103 includes two sets of discontinuously arranged second support units, the two sets of second support units being on the same horizontal plane; each second support unit has two opposing third transverse supports and a fourth transverse support connecting the two third transverse supports.

[0035] It is understood that the lifting frame 104 is positioned between the two sets of first support units and the two sets of second support units, and multiple connecting rods are positioned between the first support units and the second support units, so that the first frame 102, the second frame 103, and the lifting frame 104 form a whole, constituting the frame 100. The lifting frame 104 includes two sets of opposing vertical supports and two sets of opposing horizontal supports. The two sets of horizontal supports are located at the top and bottom of the lifting frame 104, respectively. The vertical supports and the horizontal supports form a frame structure, as shown below. Figure 2 As shown. Preferably, the frame 100 as a whole, namely the first frame 102, the second frame 103 and the lifting frame 104, is a welded structure, which has a stronger load-bearing capacity.

[0036] In this embodiment, the lifting module includes a lifting drive source 101, a first drive shaft connected to the output end of the lifting drive source 101, and two sets of lifting screws connected through the first drive shaft. The conveying transition module is connected to the movable part of the lifting screw. Specifically, the two ends of the lifting screw are respectively installed at the top and bottom of the lifting frame 104. The movable part of the lifting screw, i.e., the nut, is connected to the conveying transition module through a connecting assembly. The connecting assembly includes a connecting seat, a sliding block connected to the connecting seat, and a track slidably connected to the sliding block. Thus, the conveying transition module is connected to the connecting seat.

[0037] Furthermore, a synchronizer is connected below each of the two sets of lifting lead screws. The two synchronizers are connected by a first transmission shaft and driven by a lifting drive source 101. The lifting drive source 101 can be a commercially available servo motor, which can be selected and adjusted by those skilled in the art as needed. The synchronizer consists of a gear pair, which has the advantages of simple structure and high repeatability.

[0038] In this embodiment, as Figure 3 As shown, the conveyor transition line 200 includes a conveyor frame 201 and a conveyor drive source 202 disposed on one side of the conveyor frame 201. The conveyor frame 201 is provided with a conveyor belt, and the conveyor drive source 202 transmits power to the conveyor belt through a transmission assembly. Specifically, the transmission assembly includes two sets of synchronous pulley assemblies, which are connected by a second drive shaft. The output end of the conveyor drive source 202 is connected to the second drive shaft. The synchronous pulley assembly includes a first synchronous pulley and a second synchronous pulley respectively disposed on both sides of the conveyor frame 201, and the conveyor belt is tensioned between the first synchronous pulley and the second synchronous pulley.

[0039] In this embodiment, combined with Figure 7 and Figure 8 The flipping module includes a flipping power mechanism 300, a flipping follower mechanism 400, and a flipping mechanism 500 disposed between the flipping power mechanism 300 and the flipping follower mechanism 400. The flipping power mechanism 300 includes a flipping drive source 301 and a first flipping shaft 303 connected to the output end of the flipping drive source 301. The flipping follower mechanism 400 includes a second flipping shaft 401. The first flipping shaft 303 and the second flipping shaft 401 are respectively connected to both sides of the flipping mechanism 500. Specifically, the flipping power mechanism 300 and the flipping follower mechanism 400 are mounted on the second frame 103. The output end of the flipping drive source 301 is connected to a driving gear (not shown in the figure). The driving gear and the driven gear 302 mesh and drive each other. The driven gear 302 is disposed at the end of the first flipping shaft 303.

[0040] In this embodiment, as Figure 8 As shown, the flipping mechanism 500 includes a flipping frame 501 and clamping mechanisms disposed on both sides of the flipping frame 501. The clamping mechanisms clamp the battery module 900 in at least one direction.

[0041] Specifically, such as Figure 7 As shown, the clamping mechanism includes a first clamping drive source 502 and a first clamping plate 503 connected to the working end of the first clamping drive source 502. The first clamping drive source 502 pushes the first clamping plate 503 to approach the battery module 900 along a first direction.

[0042] The clamping mechanism also includes a second clamping drive source 504 and a second clamping plate 505 connected to the actuating end of the second clamping drive source 504. The second clamping drive source 504 pushes the second clamping plate 505 closer to the battery module 900 along a second direction. The first direction is the width direction of the flipping frame 501, and the second direction is the length direction of the flipping frame 501. Further, clamping blocks 506 are mounted on the surface of the second clamping plate 505 facing the battery module 900. The clamping blocks 506 have different mounting positions on the second clamping plate 505, allowing the mounting positions to be changed according to the product size of the battery module 900, avoiding the need to remanufacture the clamping mechanism and changeover tooling, thereby avoiding wasted time and labor maintenance costs. The clamping mechanism provided in this embodiment can save changeover time and reduce the labor intensity of workers.

[0043] It should be noted that the flipping frame 501 is roughly rectangular in shape, meaning it has a long side and a wide side. The long side is the side with a relatively longer length, and the wide side is the side with a relatively shorter length. The first clamping drive source 502 and the second clamping drive source 504 can be commercially available cylinders, which can be selected and adjusted by those skilled in the art as needed.

[0044] The working principle of the clamping mechanism is as follows: the first clamping plate 503 and the second clamping plate 505 clamp the battery module 900, and then the flipping mechanism 500 rotates around the first flipping shaft 303 and the second flipping shaft 401.

[0045] In this embodiment, combined with Figure 4 and Figure 5 The limiting mechanism 600 is a purely mechanical structure without any electrical control components, thus eliminating the risk of electrical malfunction. Specifically, the sliding surface of the push block 601 is an inclined plane, and the plane containing the inclined plane forms a first preset angle with the horizontal plane. The reset groove on the track plate 604 forms a second preset angle with the horizontal plane. The reset element 607 can be a compression spring. Furthermore, the limiting mechanism 600 also includes a guide rail 610 and a slider 609 that slides along the guide rail 610. The guide rail 610 is fixed to the base 603, and the slider 609 and the slide plate 605 are in contact, causing the slide plate 605 to slide along the direction set by the guide rail 610.

[0046] The working principle of the limiting mechanism 600 is as follows: When the pallet 800 descends to the height of the conveyor transition line 200, the pusher 601 pushes the sliding plate bearing 611, thereby pushing the slide plate 605 backward. The slide plate 605 drives the track plate 604 backward together, and the track plate 604 presses down the reset bearing (not shown in the figure), thereby driving the pallet stop pin 602 down until the height of the pallet stop pin 602 is lower than the bottom surface of the pallet 800. At this time, the pallet 800 can flow in and out of the conveyor transition line 200. When the pallet 800 leaves the conveyor transition line 200, the reset element 607 pushes out the slide plate 605, and the slide plate 605 drives the track plate 604 to extend. The track plate 604 lifts the reset bearing, thereby driving the pallet stop pin 602 to rise. At this time, the height of the pallet stop pin 602 is higher than the bottom surface of the pallet 800. At this time, when the pallet 800 flows out on the conveyor transition line 200, it will be blocked by the pallet stop pin 602, thereby preventing the pallet 800 from slipping off the conveyor transition line 200 during the lifting process.

[0047] In this embodiment, as Figure 6 As shown, the connecting block 701 is roughly triangular pyramid in shape, so the connecting block 701 has three surfaces. The working end of the lifting drive source is connected to one of the surfaces of the connecting block 701, and two lifting bearings 702 are provided on the same edge.

[0048] The working principle of this embodiment is as follows: The current conveyor line delivers the front pallet 800 and the battery module 900 it carries to the conveyor transition line 200. A limiting mechanism 600 blocks the front pallet 800, and a lifting mechanism 700 fixes the pallet's position and disengages it from the conveyor transition line 200. A lifting module raises the pallet 800 and battery module 900 together to the height of the flipping mechanism 500, where the clamping mechanism of the flipping mechanism 500 holds the battery module 900. The lifting module lowers the empty pallet 800 to the pallet return height, while simultaneously, the flipping mechanism 500 flips the battery module 900.

[0049] The subsequent conveyor line delivers an empty rear pallet 800 to the conveyor transition line 200. A limiting mechanism 600 blocks the pallet 800, and a lifting mechanism 700 fixes the pallet's position and detaches it from the conveyor transition line 200. A lifting module raises the pallet 800 to the height of the flipping mechanism 500 to receive the flipped battery module 900. The flipping mechanism 500 releases the battery module 900, and the lifting module lowers the rear pallet 800 and battery module 900 together to the height of the subsequent conveyor line. The pallet 800 is then conveyed out of the battery module flipping device by the conveyor transition line 200.

[0050] This embodiment also provides a battery production line, including the aforementioned battery module flipping equipment. It should be noted that the focus of this invention lies in the improvement of the battery module flipping equipment; the remaining processes of the battery production line are common knowledge and are irrelevant to this invention, and will not be described further here.

[0051] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
