Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery packing, in particular to a module packing machine suitable for multi-size battery cells. Background Art

[0002] With the development of the manufacturing industry, the production technology in the production workshop is becoming more and more efficient, and the market has increasingly strict requirements for production processes and product quality. This has also led to higher requirements for the production of battery cell modules in the lithium battery industry. Most of the current battery cell packaging and tying technologies in the market are mainly manual. During the manual tying process, problems such as loose tying straps, misaligned tying straps, and accidental collisions of the battery cell modules often occur, damaging the batteries, resulting in greater economic losses when the battery cell modules are installed in the battery box and put into use.

[0003] At present, some enterprises have also made improvements in this regard. For example, the invention patent with the publication number CN102398692A discloses a battery packing machine. In this invention patent, a push rod structure is provided to compress the battery cell module. This solution basically solves the problem of loose tying straps during manual grouping and packing. However, the design of its structure makes it have a single battery size for packing and low compatibility. Summary of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the utility model aims to provide a battery cell module packing machine with a simple structure, convenient operation, and high compatibility.

[0005] To achieve the above object, the utility model provides a module packing machine suitable for multi-size battery cells, which includes a support plate, a pressing plate, and a cylinder. The support plate is provided with a first limiting plate and a second limiting plate. The support plate is provided with multiple threaded mounting holes a for the second limiting plate, and the support plate is also provided with multiple threaded mounting hole positions b for adjusting the position of the cylinder. The pressing plate and the first limiting plate are respectively provided with a threading plate a and a threading plate b with magnetic attraction, and the threading plate a and the threading plate b guide and limit the tying straps.

[0006] Based on the above, when packing lithium batteries of different sizes, the position of the second limiting plate can be adjusted by using multiple threaded mounting holes a on the support plate to meet the tying requirements of battery cells of different sizes. At the same time, since the stroke of the cylinder is fixed, when different strokes are required, the position of the cylinder can be adjusted through the threaded mounting hole positions b to meet the requirements of different strokes. The threading plate a and the threading plate b are used to guide and limit the tying straps to prevent the tying straps from shifting during the packing process.

[0007] Further, a plurality of tie strap grooves are provided on the pallet. The tie strap grooves extend from the first limiting plate towards the cylinder direction, and the tie strap grooves are longer than the second limiting plate.

[0008] Based on the above, the tie strap can pass through the tie strap groove from one end of the battery cell module to the other end. The tie strap groove is longer than the second limiting plate to ensure that the tie strap groove can be used within the limiting range of the second limiting plate.

[0009] Further, rib plate structures are provided on the non-working sides of the first limiting plate and the second limiting plate. The first limiting plate is fixedly installed at one end of the pallet, and the second limiting plate is fixedly installed on the pallet through the threaded mounting hole a.

[0010] Based on the above, the rib plate structure can play a role in fixedly supporting the first limiting plate and the second limiting plate, making the structures of the first limiting plate and the second limiting plate more stable.

[0011] Further, the cylinder is provided with a mounting and fixing seat, and the mounting and fixing seat is fixedly installed on the pallet through a threaded mounting hole b.

[0012] Based on the above, the mounting and fixing seat is used to fixedly install the cylinder, and the position of the cylinder on the pallet can be adjusted through the threaded mounting hole b.

[0013] Further, a cylinder start-stop switch is also provided on the pallet.

[0014] Based on the above, the cylinder start-stop switch is used to control the forward and return strokes of the cylinder.

[0015] Further, four tie strap grooves are provided.

[0016] Based on the above, the corresponding tie strap groove can be selected according to different battery cell sizes to package the battery cell module.

[0017] Further, the first limiting plate and the pressing plate are made of metal materials and can be adsorbed by a magnet.

[0018] Based on the above, the first limiting plate and the pressing plate are made of metal materials, and the magnetic threading plates a and b can be adsorbed on them.

[0019] Further, both the threading plate a and the threading plate b are made of magnetic materials. The threading plate a and the threading plate b are respectively adsorbed on the pressing plate and the first limiting plate by magnetic force, and at the same time, the threading plate a and the threading plate b are located on the same horizontal plane.

[0020] Based on the above, the magnetic force between the wire threading plate a and the wire threading plate b is sufficient to fix them on the pressing plate and the first limiting plate respectively, but the wire threading plate a and the wire threading plate b can still be slowly pushed by hand to adjust their positions, improving the compatibility and convenience of the bundling machine.

[0021] Further, the wire threading plate a and the wire threading plate b are made of non-magnetic materials.

[0022] Based on the above, the threaded holes can be used to fixedly install the non-magnetic wire threading plate a and wire threading plate b.

[0023] Further, several groups of threaded mounting holes c and several groups of threaded mounting holes d are respectively arranged on the pressing plate and the first limiting plate. The wire threading plate a and the wire threading plate b are fixedly installed through the threaded mounting holes c and the threaded mounting holes d. At the same time, the wire threading plate a and the wire threading plate b are located on the same horizontal plane.

[0024] Based on the above, when the magnetic force between the wire threading plate a and the wire threading plate b is not strong, the positions of the wire threading plate a and the wire threading plate b can be adjusted and fixedly installed through the threaded mounting holes c and the threaded mounting holes d.

Detailed Embodiments

[0031] To more clearly illustrate the above features of the present utility model and the purposes to be achieved, the following further describes the present utility model in combination with the drawings and specific embodiments.

[0032] AsFigures 1 to 5 As shown in the figure, a module packaging machine adapted to multi-size battery cells includes a pallet 1, a pressing plate 5, and a cylinder 2.

[0033] A battery cell packaging station composed of a first limiting plate 3 and a second limiting plate 4 is provided on the pallet 1. Rib plates are provided on both sides of the first limiting plate 3 and the second limiting plate 4 to enhance the structural stress stability. The cylinder 2 drives the pressing plate 5 to press the battery cell 9 at the battery cell packaging station. A plurality of threaded mounting holes a 11 for adjusting the mounting position of the second limiting plate 4 and a plurality of threaded mounting holes b 12 for adjusting the mounting position of the cylinder 2 are further provided on the pallet 1. When packaging lithium battery cells of different sizes, the position of the second limiting plate 4 can be adjusted by using the plurality of threaded mounting holes a 11 on the pallet 1 to meet the packaging requirements of battery cells 9 of different sizes. At the same time, since the stroke of the cylinder 2 is fixed, when different strokes are required, the position of the cylinder 2 can be adjusted through the threaded mounting holes b 12 to achieve different stroke requirements.

[0034] A plurality of tie strap grooves 13 are provided on the pallet 1. The tie strap grooves 13 extend from the first limiting plate 3 towards the cylinder 2. The tie strap grooves 13 are longer than the second limiting plate 4. The tie strap can pass through the tie strap grooves 13 from one end of the battery cell module to the other end. The tie strap grooves 13 are longer than the second limiting plate 4 to ensure that the tie strap grooves 13 can be used within the limiting range of the second limiting plate 4. As Figure 1 shown in the figure, the pallet 1 is provided with 4 tie strap grooves 13. The tie strap grooves 13 to be used can be selected according to the size of the battery cell 9. At this time, the tie strap is in the position of the first and the third tie strap grooves 13. In addition, the pallet 1 is further provided with a cylinder start-stop switch 8 for controlling the reciprocating stroke of the cylinder 2.

[0035] One side of the pressing plate 5 is fixedly connected to the output end of the cylinder 2, and a wire threading plate a 6 is provided on the other side. A wire threading plate b 7 is also provided on the first limiting plate 3. When the wire threading plate a 6 and the wire threading plate b 7 are made of magnetic materials, the wire threading plate a 6 and the wire threading plate b 7 can be respectively adsorbed on the pressing plate 5 and the first limiting plate 3 by magnetic force. When the wire threading plate a 6 and the wire threading plate b 7 are made of non-magnetic materials, threaded mounting holes 51 and 31 are respectively provided on the pressing plate 5 and the first limiting plate 3, and the positions of the wire threading plate a 6 and the wire threading plate b 7 are adjusted and fixedly installed through the threaded mounting hole c 51 and the threaded mounting hole d 31. The wire threading plate a 6 and the wire threading plate b 7 are used to lock the position of the tie strap to prevent the tie strap from shifting during the packing process. For battery cell packing modules of different sizes, the wire threading plate a 6 can be freely pushed on the pressing plate 5 to adjust to a suitable position. Similarly, the wire threading plate b 7 can be freely pushed on the first limiting plate 3 to adjust to a suitable position.

[0036] The working process of the present utility model is as follows: First, stack the battery cells 9 and place them in the battery cell packing station, add thin foam and end plates on both the left and right sides, adjust the position of the second limiting plate 4 according to the size of the battery cells 9 and fix it with screws. Then, adjust the wire threading plate b 7 on the first limiting plate 3 to align the two grooves on the wire threading plate b 7 with the tie strap grooves 13 respectively. Then, closely place the stacked battery cells 9 against the first limiting plate 3 and the second limiting plate 4, pass the tie strap through the tie strap groove 13 and around the battery cells for one week. Then, twist the cylinder start-stop switch 8, and the pressing plate 5 moves towards the battery cells 9. When the wire threading plate a 6 approaches the battery cell module, adjust the wire threading plate a 6 and the wire threading plate b 7 to correspond to the same tie strap groove 13. Pass the tie strap through the inner groove of the wire threading plate b 7, and then twist the cylinder start-stop switch 8 until the wire threading plate b 7 contacts the end plate of the battery cell module and slightly presses it. Stack the two ends of the tie strap together, place them in the pressing groove of the electric strapping machine, set the parameters of the electric strapping machine and then start it. After the tie strap is fixed, cut off the excess section, pull it out, and then move the electric strapping machine away. Then, twist the cylinder start-stop switch 8 in the reverse direction until the pressing plate 5 resets, and the battery cell module strapping is completed.

[0037] The above is only the optimal solution embodiment of the present utility model, and is not used to limit the present utility model. Various modifications or substitutions made by those skilled in the art to the present utility model without departing from the essence and protection scope of the present utility model should also be within the protection scope of the present utility model.
