Description

Technical Field

[0001] The present invention relates to the technical field of assembly, and in particular to an assembly system for an energy storage battery pack. Background Art

[0002] Soft-pack lithium battery is a type of energy storage battery. Soft-pack battery refers to a battery with aluminum-plastic film as the outer packaging. Compared with square aluminum shell batteries and cylindrical batteries, soft-pack batteries generally expand first after damage, or break through the seal to release energy, and are not easy to explode. Relatively speaking, they have higher safety performance. In addition, soft-pack batteries of the same capacity are lighter than square aluminum shell batteries and have higher energy density.

[0003] According to the voltage and capacity required for the final use, multiple soft-pack lithium batteries need to be assembled to form a corresponding energy storage battery pack. In order to better protect the soft-pack batteries, epoxy plates are often inserted between two adjacent soft-pack batteries during assembly to insulate and isolate them. After assembly, they also need to be pressed to ensure that they can be installed in the bracket battery box. In this process, installing the soft-pack batteries one by one is inefficient, which affects the installation efficiency. Before installation, they also need to be tested for power connection to ensure that the battery performance meets the standards, making it difficult for the entire assembly system to efficiently complete the assembly of the energy storage battery pack. Based on this, an assembly system for an energy storage battery pack is proposed. Summary of the invention

[0028] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "mounted / connected", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Example, see Figures 1 to 6 , an assembly system for energy storage battery packs, including an assembly stand 1, on which a processing assembly seat 2 is rotatably arranged, a rotatable mounting opening adapted to the processing assembly seat 2 is opened in the assembly stand 1, a rotating motor 26 is arranged in the rotating mounting opening, the processing assembly seat 2 is rotatably arranged in the rotating mounting opening, and is fixedly connected to the output end of the rotating motor 26.

[0030] It should be noted that the processing assembly seat 2 is rotatably connected to the assembly stand 1 so that when the soft-pack battery assembly frame seat 3 on the processing assembly seat 2 needs to be adjusted, it can be flexibly adjusted by rotating the motor 26.

[0031] A soft-pack battery assembly frame seat 3 is arranged on the processing and assembly seat 2, and a lifting base 27 is arranged inside the soft-pack battery assembly frame seat 3. An electric push rod 28 connected to the lifting base 27 is provided inside the processing and assembly seat 2. The lifting base 27 controlled by the electric push rod 28 can facilitate the assembled soft-pack battery pack to be taken out from the soft-pack battery assembly frame seat 3.

[0032] An L-shaped positioning frame bar 4 is arranged at the four corners of the soft-pack battery assembly frame seat 3. The positioning frame bar 4 is designed according to the size of the soft-pack battery. A positioning rail mounting member is arranged on one side of the positioning frame bar 4. Furthermore, the positioning rail mounting member includes a vertical limiting rail 15 fixedly arranged on the positioning frame bar 4, and a power connection strip 16 is arranged on the vertical limiting rail 15. The sliding limiting block 11 is slidably arranged in the vertical limiting rail 15, and a power connection contact block 17 adapted to the power connection strip 16 is arranged on the back.

[0033] Among them, the power contact block 17 is slidably connected to the power plug strip 16, and the electrical signal can be connected during the sliding process. The internal connection is through the sliding contact end, which is the existing technology and will not be described in detail here. It mainly ensures that the assembled assembly fixing part can be moved to any position on the positioning rail mounting part.

[0034] A plurality of assembly fixing parts are detachably installed on the positioning electric rail mounting part. Furthermore, the assembly fixing parts include a fixing lifting bar 29 and sliding limit blocks 11 fixedly arranged at both ends of the fixing lifting bar 29. A telescopic opening is opened in the fixing lifting bar 29. The inner wall of the telescopic opening is connected to a magnetic repulsion bar 12 through a reset spring. The thickness of the magnetic repulsion bar 12 is very thin. The magnetic repulsion bar 12 is fixedly connected to an insertion positioning bar 13. The inner wall of the telescopic opening is provided with an electromagnetic bar 14 that magnetically repels the magnetic repulsion bar 12.

[0035] It should be noted that when the magnetic repulsion strip 12 is not affected by the magnetic force of the electromagnetic strip 14, it is in a state of being stored inside the telescopic opening. After placing multiple soft-pack batteries on the soft-pack battery assembly frame 3, the electromagnetic strip 14 can be powered so that the insertion positioning strip 13 under the action of its magnetic force can be inserted into two adjacent soft-pack batteries (the soft-pack battery is not a rectangular shell, its surface aluminum-plastic film is a carrier, and its side is arc-shaped, which allows the insertion positioning strip 13 to be inserted between two soft-pack batteries), thereby realizing the separation of multiple soft-pack batteries one by one through the insertion positioning strip 13.

[0036] A regulating motor 5 is arranged in the processing and assembly seat 2. The regulating motor 5 is a prior art and will not be described in detail here. The output end of the regulating motor 5 is connected to the vertical rotating shaft 6 through a worm and worm gear transmission. Furthermore, the worm and worm gear transmission includes a transmission port opened in the processing and assembly seat 2. The regulating motor 5 is in the transmission port, and its output end is fixedly connected to a worm shaft 18. The bottom end of the vertical rotating shaft 6 passes through the transmission port and is fixedly connected to a transmission worm wheel 19 meshing with the worm shaft 18. Through the setting of the worm and worm gear transmission, the control of the transmission worm wheel 19 to rotate can be driven by the regulating motor 5, thereby achieving the control of the rotation of the sequential lifting parts connected to the vertical rotating shaft 6.

[0037] A plurality of sequential lifting members are arranged on the vertical rotating shaft 6; further, the sequential lifting members include connecting rings 20 evenly arranged on the outer wall of the vertical rotating shaft 6, and the outer wall of the connecting ring 20 is fixedly connected with a fan-shaped lifting plate 21, and the fan-shaped areas of the plurality of fan-shaped lifting plates 21 gradually decrease from bottom to top, and the edges of the fan-shaped lifting plates 21 are arranged in an inclined surface, so as to achieve the effect of gradually lifting the soft-pack battery through the inclined surface;

[0038] It is worth noting that the fan-shaped lifting plate 21 gradually decreases in area from bottom to top, that is, when the vertical shaft 6 drives the sequential lifting parts to rotate, the fan-shaped lifting plate 21 below it will be inserted between the two bottom locking lifting bars 29 first during the rotation process, and under the action of the resistance force of the inclined surface, the upper locking lifting bar 29 and the multiple locking lifting bars 29 above it are moved upward together. After the lifting is completed, the fan-shaped lifting plate 21 above it is inserted between the corresponding two locking lifting bars 29, thereby gradually achieving the effect of lifting multiple soft-pack batteries one by one, and because the spacing between the fan-shaped lifting plates 21 is consistent, it can ensure that the spacing between multiple soft-pack batteries is the same, meeting the requirements of positioning during later inspection and inserting epoxy boards for isolation.

[0039] A U-shaped support frame 7 is provided on the assembly stand 1, and a pressure hydraulic cylinder 8 is provided on the U-shaped support frame 7. A control flat plate 9 is provided at the output end of the pressure hydraulic cylinder 8. The control flat plate 9 applies downward pressure to press a plurality of soft-pack batteries together to avoid gaps between them, which affects the final insertion effect. A pre-assembly detection device for detecting the soft-pack batteries is provided on the assembly stand 1 located on one side of the U-shaped support frame 7. The pre-assembly detection device includes a detection panel 22 provided on the assembly stand 1, and an arc-shaped contact member 23 for performing termination detection on the positive and negative electrodes of the soft-pack batteries is provided on the detection panel 22;

[0040] It is worth noting that the positive and negative electrodes of the soft-pack battery are both at one end and arranged on both sides, wherein the arrangement of the arc-shaped contact member 23 can satisfy the effect of contacting the positive and negative electrodes of the soft-pack battery respectively.

[0041] A pre-assembly frame 10 is provided on the assembly stand 1 located on the other side of the U-shaped support frame 7. The pre-assembly frame 10 includes a pre-insertion interface 24 opened thereon, and a plug-in assembly port 25 adapted to the pre-insertion interface 24 is opened on the positioning frame strip 4 located on one side of the pre-assembly frame 10. The setting of the pre-assembly frame 10 can realize the insertion of the epoxy plate to be inserted between the soft-pack batteries into the pre-insertion interface 24 in advance, so that during assembly, it is convenient to quickly insert the epoxy plate into the soft-pack battery, thereby achieving a rapid processing effect.

[0042] When assembling the soft-pack batteries, the soft-pack batteries are stacked and placed on the soft-pack battery assembly frame 3. Due to the positioning of the positioning frame bars 4 arranged at the four corners, the multiple soft-pack batteries on the soft-pack battery assembly frame 3 are in a relatively neatly placed state. At this time, the pressure hydraulic cylinder 8 can be used to drive the control flattening plate 9 to move downward, so that the control flattening plate 9 moves downward to flatten the stacked soft-pack batteries, thereby avoiding gaps between adjacent soft-pack batteries that affect the subsequent assembly process;

[0043] The assembly fixing parts installed on both sides of the positioning rail mounting parts are energized, so that the electromagnetic strip 14 generates magnetic force, so that the insertion positioning strip 13 under the action of the magnetic force moves outward and is inserted into two adjacent soft-pack batteries (the soft-pack battery is not a rectangular shell, its surface aluminum-plastic film is a carrier, and its side is an arc-shaped setting, so that the insertion positioning strip 13 can be inserted between two soft-pack batteries), so that multiple soft-pack batteries can be inserted into both ends of the insertion positioning strip 13 to separate the soft-pack batteries;

[0044] The control and regulation motor 5 drives the worm shaft 18 connected to its output end to rotate, and the vertical shaft 6 connected to the worm shaft 18 through the transmission worm gear 19 will rotate, and drive the sequential lifting parts connected thereto to rotate. Under the action of the fan-shaped lifting plate 21 whose fan-shaped area gradually decreases from bottom to top, the fan-shaped lifting plate 21 will be inserted one by one from bottom to top between the adjacent fixed lifting bars 29. Under the action of the thickness of the fan-shaped lifting plate 21, the soft-pack battery is supported and a gap for the epoxy plate to be inserted is generated;

[0045] At this time, before assembling the epoxy board, the processing assembly seat 2 can be controlled to rotate by rotating the motor 26, so that the connection terminal of the soft-pack battery installed on the soft-pack battery assembly frame 3 slides onto the arc contact piece 23 and contacts the connection contact on the arc contact piece 23. The battery detection module on the detection panel 22 is used to perform a pre-assembly inspection on a single soft-pack battery, and unqualified batteries are removed in time to ensure the quality of the assembled energy storage battery pack;

[0046] While positioning, adjusting and testing the soft-pack batteries, the epoxy boards can be inserted one by one into the pre-insertion interfaces 24 on the pre-assembly frame 10. During assembly, the epoxy boards are directly inserted inward, which facilitates and quickly inserts the epoxy boards into the gaps between the soft-pack batteries, facilitates and quickly performs assembly processing, and significantly reduces work intensity.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
