Description

Technical Field

[0001] The present application belongs to the field of battery cell transportation, and in particular, the present application relates to a battery cell caching mechanism and a battery cell tidying device. Background Art

[0002] Before battery strings are assembled, they need to be aligned and positioned to adjust the spacing between adjacent battery cells and the alignment of the battery cells. In the prior art, for cost considerations, half a string of battery cells is usually aligned each time, and then a robot moves the aligned half string of battery cells from the alignment station to the assembly station, where two half strings of battery cells are accumulated before assembly.

[0003] However, since the straightening station and the string assembly station are not in a straight line, the movement path of the robot for transporting half a string of battery cells will be arc-shaped, making it difficult to ensure that the robot places the battery cells in the same position at the string assembly station each time; there will also be movement errors when transporting half a string of battery cells, so the two half strings of battery cells placed successively at the string assembly station are prone to positional misalignment, resulting in poor flatness of the battery string after string welding. Utility Model Content

[0004] The example of the present application provides a battery cell caching mechanism and a battery cell tidying device, which can improve the posture stability of the battery when caching during the string welding process, thereby improving the quality of subsequent string welding.

[0005] The solution of this application example is implemented through the following contents.

[0006] A battery cell cache mechanism, comprising:

[0007] frame;

[0008] Two parallel buffer trays, the two buffer trays are escalably arranged on the frame, a plurality of adsorption trays are respectively arranged on the sides of the two buffer trays close to each other, and the conveying track of the battery sheet passes through the area between the two buffer trays;

[0009] A conveying assembly is configured to convey the battery cell to the buffer tray along a conveying track of the battery cell, the conveying assembly comprising a support plate and a boss disposed on the support plate, the boss being used to absorb the battery cell and keep the battery cell in a preset plane;

[0010] The buffer tray has a descending posture and an ascending posture. When the buffer tray is in the descending posture, the adsorption tray is higher than the support plate and lower than the boss. When the buffer tray is in the ascending posture, the adsorption tray is higher than the boss.

[0011] The user can use the battery cell caching mechanism in the following manner. During use, the battery cell can be adsorbed and temporarily fixed to the conveying assembly. The conveying assembly then moves to the corresponding position of the spacing area of ​​the cache tray. The cache tray rises so that the battery cell released by the conveying assembly is adsorbed and lifted by the adsorption tray, thereby detaching from the conveying assembly. The cache tray then descends, and then the conveying assembly conveys the battery cell to the specified position again, and then the cache tray is again placed in place through the adsorption tray after being lifted and lowered.

[0012] In some embodiments, the conveying assembly also includes two battery support rods, which are respectively arranged on two opposite sides of the boss, and the boss and the battery support rods are used to jointly carry the battery cells. The width of the adsorption tray is smaller than the distance between the two battery support rods, and gaps are formed between the two ends of the battery support rods and the support plate below for the adsorption tray to pass through.

[0013] In the above process, the adsorption support can adsorb and fix the battery cell, and the battery support rod can provide a battery cell support part outside the boss. Through such a structure, the battery cell is well supported and constrained at different positions, so that a greater posture stability is obtained. Because the current battery cell is very thin, the original boss is used to support the middle position of the battery cell, and the two ends of the battery cell will droop. Therefore, the above-mentioned battery support rod is needed to assist in carrying the battery cell.

[0014] In some embodiments, a plurality of rows of first adsorption holes are formed on the boss, and the plurality of rows of first adsorption holes adsorb the battery cells onto the boss through negative pressure.

[0015] Multiple rows of first adsorption holes are used to adsorb the battery cells onto the bosses to prevent the battery cells from shifting during transportation, thereby ensuring that the position of the battery cells on the conveying assembly is stable.

[0016] In some embodiments, the battery cell cache mechanism further includes a first driving member, a plurality of conveying assemblies are provided, each conveying assembly is used to carry a battery cell, and the first driving member is used to drive each conveying assembly to slide independently along the conveying track of the battery cell.

[0017] The first driving member is used to drive the multiple conveying assemblies respectively, so as to realize the independent conveying of the battery slices on each conveying assembly.

[0018] In some embodiments, the number of adsorption trays provided on each buffer tray is the same as the number of conveying components.

[0019] By arranging adsorption trays on the buffer tray in the same number as the conveying components, it is ensured that each battery cell on the conveying component is lifted and supported by the adsorption tray.

[0020] In some embodiments, the two cache trays are provided with the same number of adsorption trays, which correspond to each other to form at least two groups, and the two adsorption trays in the same group are aligned with each other.

[0021] The adsorption trays are distributed in groups, and the adsorption trays in the same group are aligned so that the battery cells are stably supported.

[0022] In some embodiments, the distance between two adsorption trays in the same group is greater than the length of the boss.

[0023] The adsorption tray is arranged at a distance greater than the length of the battery, so that when the adsorption assembly conveying assembly slides between the two buffer trays, the buffer tray is just lifted and carries the battery sheet.

[0024] In some embodiments, the battery cell cache mechanism further includes a synchronous drive mechanism disposed on the frame to drive the cache tray, and the two cache trays are constructed to be driven by the synchronous drive mechanism to rise and fall synchronously.

[0025] The synchronous drive motor can ensure the synchronous lifting of the two buffer trays, so that the positions of the battery cells corresponding to the adsorption trays are subjected to synchronous force during the lifting process, thereby ensuring that the battery cells do not have problems such as skewing.

[0026] In some embodiments, the synchronous drive mechanism includes a servo motor and a ball screw mechanism that are coupled through a pulley assembly, and the cache mechanism achieves the lifting and lowering of the cache tray by lifting and lowering the threaded sleeve of the ball screw mechanism relative to the screw rod.

[0027] The pulley assembly transmission allows the servo motor and ball screw mechanism to be installed at a relatively long distance, allowing for more flexible position and posture configuration of each structure. In addition, the transmission is smooth, the noise is low, the vibration is small, and the installation is easy.

[0028] The present application also discloses a battery cell arranging device, comprising: an arranging mechanism and a battery cell caching mechanism as described above, wherein: the battery cell caching mechanism is arranged in the process downstream of the arranging mechanism, the conveying component is configured to carry the arranging battery cell group at the arranging mechanism, and the arranging mechanism is used to arrange the battery cell group carried by the conveying component; the conveying component is also configured to convey the arranging battery cell group to the battery cell caching mechanism.

[0029] During use, the battery cell caching mechanism of the present application can absorb the battery through the boss of the conveying assembly, and because the battery support rod is set to support the battery outside the boss and the lateral area of ​​the boss, it can prevent the battery cell from tilting. In addition, the adsorption support can also support the battery, which improves the stability of the cache when lifting the battery cell, and avoids the position deviation of the regular battery cell during caching.

[0038] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0039] Combination Figure 1 , Figure 2 as well as Figure 3 As shown, this embodiment provides a battery cell buffer mechanism. Figure 1 A schematic diagram of the three-dimensional structure of the battery cell buffer mechanism provided in this embodiment, Figure 2 A schematic diagram of the lifting structure of the buffer support plate provided in this embodiment, Figure 3 A schematic diagram of the coordination between the buffer tray and the conveying assembly provided in this embodiment.

[0040] The embodiment of the utility model provides a battery cell buffer mechanism, comprising a frame 1, two parallel buffer trays 2 and a conveying assembly 3.

[0041] The rack 1 is used as the supporting body of the battery cell cache mechanism to support the cache tray 2, and is usually extended along the conveying direction of the battery cells. The rack 1 can be an integrally formed mechanical structure or an assembled structure, and can provide support. In this embodiment, two separate brackets are combined to form the rack 1.

[0042] Two buffer trays 2 are arranged on opposite sides of the frame 1 in a liftable manner. A plurality of adsorption platforms 21 are respectively arranged on the sides of the two buffer trays 2 that are close to each other. The conveying track of the battery cell passes through the area between the two buffer trays 2. The extending direction of each buffer tray 2 is the conveying direction of the battery cell. When the battery cell passes through the area between the buffer trays 2, the adsorption platforms 21 arranged on the two buffer trays 2 can support the battery cell.

[0043] The conveying assembly 3 is constructed to convey the battery cells to the cache tray 2 along the conveying trajectory of the battery cells. The conveying assembly 3 includes a support plate 31 and a boss 32 arranged on the support plate 31. The boss 32 is used to absorb the battery cells and keep the battery cells in a preset plane; wherein, the extension direction of the boss 32 is the relative direction of the two cache trays 2, ensuring the stability of the battery cells when the boss 32 supports the battery cells.

[0044] The conveying assembly 3 carries the battery cells and moves in the area between two parallel buffer trays 2. The battery cells are supported and adsorbed by providing a support plate 31 and a boss 32 on the support plate 31, so that the battery cells remain stable during the conveying process.

[0045] In addition, for the above-mentioned battery cell cache mechanism, the cache tray 2 has two working conditions, exemplified by a descending posture and an ascending posture. When the cache tray 2 is in a descending posture, the adsorption tray 21 is higher than the support plate 31 and lower than the boss 32. When the cache tray 2 is in an ascending posture, the adsorption tray 21 is higher than the boss 32.

[0046] The buffer tray 2 is in the initial position when it is in the descending posture, and the adsorption tray 21 is higher than the support plate 31 and lower than the boss 32, so that the lower end surface of the battery cell on the boss 32 is higher than the upper end surface of the adsorption tray 21. At this time, the battery cell is supported by the boss 32, and the adsorption tray 21 does not contact the battery cell. When the buffer tray 2 is in the ascending posture, that is, the buffer tray 2 starts to rise from the initial position, the adsorption tray 21 contacts the battery cell and supports the battery cell, so that the battery cell is separated from the support of the boss 32, and then separated from the conveying component 3 and cached on the buffer tray 2.

[0047] For example, the user can use the battery cell caching mechanism in the following manner. During use, the battery cell can be adsorbed and temporarily fixed to the conveying component 3. The conveying component 3 then moves to the corresponding position of the spacing area of ​​the cache tray 2. The cache tray 2 rises so that the battery released by the conveying component 3 is adsorbed and lifted by the adsorption tray 21, thereby detaching from the conveying component 3. The cache tray 2 then descends, and then the conveying component 3 conveys the battery to the specified position again, and then the cache tray 2 is again placed in place through the adsorption tray 21 after being lifted and lowered, thereby realizing the overall transportation of multiple groups of battery cells.

[0048] Recombination Figure 3 As shown, in some embodiments, the conveying assembly 3 also includes two battery support rods 33, and the two battery support rods 33 are respectively arranged on two opposite sides of the boss 32, and the boss 32 and the battery support rods 33 are used to jointly carry the battery cells, and the width of the adsorption tray 21 is smaller than the distance between the two battery support rods 33, and gaps for the adsorption tray 21 to pass through are formed between the two ends of the battery support rods 33 and the support plate 31 below.

[0049] During use, the battery cell caching mechanism of the present application can absorb the battery cell through the boss 32 of the conveying assembly 3, and because the battery support rod 33 is arranged outside the boss 32 and the lateral area of ​​the boss 32 to support the battery, the battery cell is prevented from tilting. In addition, the adsorption support 21 can also support the battery, which improves the stability of the cache when lifting the battery cell, and avoids the positional displacement of the regular battery cell during caching.

[0050] Combination Figure 1 and Figure 3 As shown, the extension direction of the two battery support rods 33 is the same as the extension direction of the boss 32, and they are arranged on the outside of the boss 32 to jointly support the battery cells, and the distance between the two battery support rods 33 is greater than the width of the adsorption tray 21, so that the battery cells are stable when transferred from the conveying component 3 to the cache adsorption tray 21.

[0051] In addition, gaps are formed between the two ends of the battery support rod 33 and the support plate 31 below. When the conveying assembly 3 carries the battery cells for conveying, the adsorption tray 21 can pass through the gaps.

[0052] In the above process, the adsorption support 21 can adsorb and fix the battery cell, and the battery support rod 33 can provide a battery cell support portion outside the boss 32. Through such a structure, the battery cell is well supported and constrained at different positions, thereby achieving greater posture stability.

[0053] Continue as Figure 3As shown, for example, multiple rows of first adsorption holes 321 are provided on the boss 32, and the multiple rows of first adsorption holes 321 adsorb the battery cells on the boss 32 through negative pressure. The multiple rows of first adsorption holes 321 are used to adsorb the battery cells on the boss 32 to avoid the battery from being offset during the conveying process, and ensure that the position of the battery on the conveying component 3 is stable.

[0054] Combination Figure 1 As shown, each conveying assembly 3 is used to convey a battery cell, and multiple groups of conveying assemblies 3 are used to convey multiple battery cells at the same time, and a driving source is used to provide conveying power for the conveying assembly 3. Specifically, a first driving member 4 is configured to cooperate with the conveying assembly 3 to realize the conveying of the battery cell, and move the battery cell from the regular station to the next station. There are multiple conveying assemblies 3, each of which is used to carry a battery cell, and the first driving member 4 is used to drive each conveying assembly 3 to slide independently along the conveying track of the battery cell. The first driving member 4 is used to drive multiple conveying assemblies 3 respectively to realize independent conveying of batteries on each conveying assembly 3. In addition, since each conveying assembly 3 is configured to move independently and controlled, the first driving member 4 can adjust the spacing between two adjacent conveying assemblies 3 in the process of moving multiple conveying assemblies 3 to adjust the arrangement between the battery cells.

[0055] In specific applications, when the structural dimensions of the cache tray 2 along the battery cell conveying direction are determined, the number of battery cells that it can cache is also determined accordingly, that is, the number of conveying components 3 accommodated between the two cache trays 2 is also determined accordingly.

[0056] Combination Figure 1 As shown, in this embodiment, the number of adsorption trays 21 provided on each buffer tray 2 is the same as the number of conveying components 3. Each battery on the conveying component 3 needs to be supported by a corresponding adsorption tray 21, that is, each buffer tray 2 is provided with the same number of adsorption trays 21 as the conveying components 3. By providing the same number of adsorption trays 21 as the conveying components 3 on the buffer tray 2, it is ensured that the battery cells on each conveying component 3 are lifted and supported by the adsorption tray 21.

[0057] When the number of adsorption trays 21 provided on each buffer tray 2 is the same as the number of conveying components 3, it can be ensured that each battery on the conveying component 3 is supported by two adsorption trays 21. Specifically, the number of adsorption trays 21 provided on the two buffer trays 2 is the same, and they correspond to each other to form at least two groups, and the two adsorption trays 21 in the same group are aligned with each other. The adsorption trays 21 are allocated in groups, and the adsorption trays 21 in the same group are aligned, so that the batteries are stably supported.

[0058] Combination Figure 3As shown, when the conveying assembly 3 moves the battery cells to the adsorption trays 21 arranged opposite to each other on the two parallel buffer trays 2, the support plate 31 is located below the adsorption tray 21, the two battery support rods 33 on the support plate 31 are located above the adsorption tray 21, and the boss 32 on the support plate 31 is located between the two adsorption trays 21 in the same group; that is, the distance between the two adsorption trays 21 in the same group is greater than the length of the boss 32. The adsorption tray 21 is arranged at a distance greater than the length of the battery, so that when the adsorption assembly conveying assembly 3 slides between the two buffer trays 2, the buffer tray 2 is just lifted and carries the battery cells.

[0059] In this embodiment, in order to realize the lifting and lowering of the buffer support plate 2, the attached Figure 1 and attached Figure 2 As shown, the battery cell cache mechanism further includes a synchronous drive mechanism 5 disposed on the frame 1 to drive the cache tray 2 , and the two cache trays 2 are constructed to be driven by the synchronous drive mechanism 5 to rise and fall synchronously.

[0060] Specifically, the two cache pallets 2 are arranged on opposite sides of the frame 1. When lifting, the two cache pallets 2 are lifted and lowered synchronously. The synchronous drive mechanism 5 is used to realize the simultaneous lifting of the two cache pallets 2, which can ensure the lifting synchronization of the two cache pallets 2, so that the positions of the corresponding adsorption pallets of the batteries during the lifting process are subjected to force synchronously, thereby ensuring that the batteries do not tilt or have other problems.

[0061] In one embodiment, the synchronous drive mechanism 5 includes a servo motor 51 and a ball screw mechanism 53 that are driven by a pulley assembly 52. ​​Specifically, the synchronous drive mechanism 5 includes two ball screw mechanisms 53, each of which is arranged below the buffer tray 2 on the frame 1. The two ball screw mechanisms 53 are connected by a pulley assembly 52, and the servo motor 51 is used to drive the pulley assembly 52 to rotate, thereby driving the synchronous lifting and lowering of the two ball screw mechanisms 53, so as to achieve the lifting and lowering synchronization of the two buffer trays 2.

[0062] For example, the cache mechanism can achieve the lifting of the cache tray 2 by lifting the sleeve of the ball screw mechanism 53 relative to the screw, or by using a gear combination to achieve the lifting of the cache tray 2, which will not be repeated here. In addition, the servo motor 51 of the example can also be other driving sources, such as a stepper motor, which can drive the pulley assembly 52 to rotate.

[0063] The transmission cooperation through the pulley assembly 52 allows the servo motor 51 and the ball screw mechanism 53 to be installed at a relatively long distance, thereby allowing more flexible position and posture configuration of each structure. In addition, the transmission is smooth, the noise is low, the vibration caused is small, and the installation is convenient.

[0064] Based on the same application concept, an embodiment of the present application also discloses a battery cell arranging device, including: a conveying mechanism; a arranging mechanism; and a battery cell cache mechanism; the arranging mechanism is arranged at the process upstream of the conveying mechanism, and the battery cell cache mechanism is arranged at the process downstream of the conveying mechanism, the conveying component is configured to carry the arranging battery cell group at the arranging mechanism, the arranging mechanism is used to arrange the battery cell group carried by the conveying component, and the conveying component is driven by the conveying mechanism to convey the arranging battery cells from the arranging mechanism to the battery cell cache mechanism.

[0065] The battery cell aligning device firstly aligns the battery cells through the aligning mechanism, and then the conveying mechanism transports the battery cells from the battery aligning mechanism to the battery cell caching mechanism, and the battery cell caching mechanism is used to cache the aligned battery cells, so as to facilitate the overall transportation of multiple battery cells after caching.
