DETAILED DESCRIPTION

[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0042] The following combination Figure 1 The battery core encapsulation system provided by an embodiment of the present invention is described, and the battery core encapsulation system includes: a head encapsulation component 1, a side encapsulation component 2 and a tail encapsulation component 3 arranged in sequence along the processing direction.

[0043] The head glue-wrapped assembly 1 includes: a head battery cell removal mechanism 11, a head glue-wrapped mechanism 12, a head glue-winding mechanism 13, and a sequence transfer mechanism 14. The sequence transfer mechanism 14 has multiple stations, and the head battery cell removal mechanism 11, the head glue-wrapped mechanism 12, the head glue-winding mechanism 13, and the side glue-wrapped assembly 2 correspond to a station on the sequence transfer mechanism in sequence.

[0044] In this embodiment, the sequence transfer mechanism 14 adopts a turntable structure and is driven by a turntable motor arranged at the bottom. Four workstations are provided, and each workstation corresponds to the head battery cell removal mechanism 11, the head glue wrapping mechanism 12, the head glue rolling mechanism 13 and the side glue wrapping assembly 2 respectively.

[0045] During the operation of the battery cell encapsulation system, the battery cell is loaded through the head battery cell removal mechanism 11 and enters the first station of the sequence transfer mechanism 14. The turntable motor drives the sequence transfer mechanism 14 to rotate counterclockwise to send the battery cell to the second station. The head encapsulation mechanism 12 encapsulates the battery cell head. After the encapsulation is completed, the sequence transfer mechanism 14 sends the battery cell to the third station. The roller in the head encapsulation mechanism 13 presses the battery cell head encapsulation, completing the head encapsulation of the battery cell. The sequence transfer mechanism 14 sends the battery cell to the fourth station. The battery cell then passes through the side encapsulation component 2 and the tail encapsulation component 3 in sequence, and performs side encapsulation and tail encapsulation in sequence, completing the entire encapsulation process of the battery cell.

[0046] The battery cell encapsulation system provided by the present invention sequentially arranges a head encapsulation component, a side encapsulation component and a tail encapsulation component along the processing direction, and sequentially encapsulates the head, side and tail of the battery cell, thereby realizing the automated production of battery cell encapsulation and meeting various encapsulation requirements of the battery cell. In addition, the battery cell encapsulation system is provided with a head battery cell removing mechanism, a head encapsulation mechanism, a head encapsulation mechanism and a sequence transfer mechanism in the head encapsulation component, and utilizes multiple stations of the sequence transfer mechanism to realize operations such as encapsulation of the head of the battery cell and loading and unloading of materials, thereby realizing the coordinated processing of multiple components and multiple stations and ensuring the processing efficiency of the battery cell.

[0047] Based on the above embodiments, Figure 2 As shown, the head glue encapsulation mechanism 12 comprises a head glue suction device 121, a head glue pressing device 122, and a head glue preparation device 123. The head glue suction device 121 includes a head suction cup 1211, a head suction cup cylinder 1212, a head connecting plate 1213, and a head transition block 1214. The output end of the head suction cup cylinder 1212 is connected to the head suction cup 1211 via the head connecting plate 1213 and the head transition block 1214. The head glue preparation device 123 is connected to the head suction cup 1211 and the head glue pressing device 122 via adhesive tape.

[0048] In this embodiment, there are two head encapsulation mechanisms 12: a first head encapsulation mechanism and a second head encapsulation mechanism. The first head encapsulation mechanism is used to encapsulate the upper side of the cell head, while the second head encapsulation mechanism is used to encapsulate the lower side of the cell head. The first and second head encapsulation mechanisms are symmetrically mounted above and below corresponding workstations of the transfer mechanism 14.

[0049] The head glue preparation device 123 is used to transport and cut the head glue tape, such as Figure 3 As shown, the machine comprises a rubber preparation plate 1231, a rubber preparation motor 1232, a rubber preparation slide 1233, a head rubber preparation cylinder 1234, and a head rubber preparation cutter. The rubber preparation motor 1232 drives the rubber preparation plate 1231 to move on the rubber preparation slide 1233. The head rubber preparation cutter is located on one side of the rubber preparation plate 1231. The bearing rod of the head rubber preparation cylinder 1234 is connected to the head rubber preparation cutter and is used to cut the tape on the rubber preparation plate 1231.

[0050] The head glue pressing device 122 is used to cut the tape of the head glue package, including: a head glue pressing cylinder 1221 and a head cutter 1222. The head cutter 1222 is located on one side of the head suction cup 1211, and the output end of the head glue pressing cylinder 1221 is connected to the head cutter 1222.

[0051] During operation of the head glue wrapping mechanism 12, the head glue preparation device 123 conveys the tape to the head glue suction device 121 and the head glue pressing device 122. When the tape is fully in place, the head glue pressing cylinder 1221 uses the head cutter 1222 to cut one end of the tape, and the head glue preparation cylinder 1234 uses the head glue preparation cutter to cut the other end of the tape. The cut tape is adsorbed on the head suction cup 1211. At this time, the head suction cup cylinder 1212 drives the head suction cup 1211 to press against the battery cell through the head connecting plate 1213 and the head transition block 1214, thereby wrapping the tape around the head of the battery cell.

[0052] like Figure 8 and Figure 9 As shown, the head film rolling mechanism 13 includes a film rolling base plate 131, at least one base plate cylinder 132, and at least one head press-fitting device 133. The film rolling base plate 131 is provided with guide rails, and the head press-fitting devices 133 are movably mounted on the film rolling base plate 131 via the guide rails. Each head press-fitting device 133 is equipped with a corresponding base plate cylinder 132, which is mounted on the film rolling base plate 131. The output end of the base plate cylinder 132 is connected to the head press-fitting device 133.

[0053] Among them, the head pressing device 133 includes: a head pressing bracket 134 and a head pressing cylinder 135 installed on the head pressing bracket 134, an upper roller structure 136, a lower roller structure 137 and an elastic support structure 138. The upper roller structure 136 and the lower roller structure 137 are installed at intervals from each other, and the output end of the head pressing cylinder 135 is connected to the lower roller structure 137 through the elastic support structure 138. The upper roller structure 136 and the lower roller structure 137 have similar structures, both consisting of a roller and a shoulder hinge pin. When in use, the roller is directly brought into contact with the tape on the battery cell to roll and press the tape. The elastic support structure 138 includes a connecting plate, a bearing and a spring. The bearing connects the connecting plate to the lower roller structure 137, and the spring is pre-stressed between the connecting plate and the lower roller structure 137.

[0054] During operation, the head pressing device 133 presses the battery cell with the upper roller structure 136, while the head pressing cylinder 135 drives the lower roller structure 137 to roll and press the upper and lower tapes of the battery cell head together. During this rolling and pressing process, the elastic support structure 138 applies a certain amount of pressure to the head pressing cylinder 135 and the lower roller structure 137, thereby eliminating the misalignment between the upper and lower roller structures 136 and 137 and protecting the battery cell from excessive external forces.

[0055] like Figure 1 As shown, if both sides of the battery cell need to be coated, the side coating assembly 2 includes: a side battery cell removal mechanism 21 and a side coating mechanism 22 and a side coating rolling mechanism 23 arranged in sequence on both sides along the processing direction. The side battery cell removal mechanism 21 is installed on top of the side coating mechanism 22 and the side coating rolling mechanism 23.

[0056] like Figure 4 As shown, the side glue coating mechanism 22 includes: a side glue suction device 221, a side glue pressing device 222 and a side glue preparation device 223. The side glue preparation device 223 is sequentially connected to the side glue suction device 221 and the side glue pressing device 222 through adhesive tape.

[0057] The side glue suction device 221 includes a side suction cup 2211, a side suction cup cylinder 2212, a side connecting plate 2213, and a side transition block 2214. The output end of the side suction cup cylinder 2212 is connected to the side suction cup 2211 via the side connecting plate 2213 and the side transition block 2214. The side glue preparation device 223 is connected to the side suction cup 2211 and the side glue pressing device 222 via adhesive tape.

[0058] The side glue pressing device 222 is used to cut the side-coated tape. It includes a side glue pressing cylinder 2221 and a side cutter 2222. The side cutter 2222 is located on one side of the side suction cup 2211, and the output end of the side glue pressing cylinder 2221 is connected to the side cutter 2222. The side glue preparation device 223 is used to transport and cut the side-coated tape. Its structure is the same as that of the head glue preparation device 123.

[0059] During operation of the side glue wrapping mechanism 22, the side glue preparation device 223 conveys the tape to the side glue suction device 221 and the side glue pressing device 222. Once the tape is fully in place, the side glue pressing cylinder 2221 uses the side cutter 2222 to cut one end of the tape, while the cylinder in the side glue preparation device uses the cutter to cut the other end of the tape. The cut tape is then attached to the side suction cup 2211. The side suction cup cylinder 2212 then drives the side suction cup 2211 to press against the battery cell via the side connecting plate 2213 and the side transition block 2214, wrapping the tape around the side of the cell.

[0060] The side glue rolling mechanism 23 is used to roll the glue on the side of the battery cell flat. Figure 5 As shown, the side glue rolling mechanism 23 includes a side glue rolling cylinder 231, a side glue rolling connecting plate 232, a first side roller 233, and a second side roller 234. The first side roller 233 and the second side roller 234 are installed at intervals, and the output end of the side glue rolling cylinder 231 is connected to the first and second side rollers 233, 234 via the side glue rolling connecting plate 232. After the battery cell side glue coating is delivered to the next station, the side glue rolling cylinder 231 controls the position of the first and second side rollers 233, 234 via the side glue rolling connecting plate 232. The first and second side rollers 233, 234 clamp the battery cell, thereby pressing the glue coating on the side of the battery cell against the surface of the cell.

[0061] like Figure 1 As shown, the tail glue-wrapping assembly 3 includes: a tail battery cell removal mechanism 31 and a tail glue-wrapping mechanism 32 and a tail glue-rolling mechanism 33 arranged in sequence along the processing direction. The tail battery cell removal mechanism 31 is installed on top of the tail glue-wrapping mechanism 32 and the tail glue-rolling mechanism 33.

[0062] like Figure 6 As shown, the tail glue wrapping mechanism 32 includes: a tail glue suction device 321, a tail glue pressing device 322 and a tail glue preparation device 323. The tail glue preparation device 323 is connected to the tail glue suction device 321 and the tail glue pressing device 322 in sequence through adhesive tape.

[0063] The tail glue suction device 321 includes a tail suction cup 3211, a tail suction cup cylinder 3212, a tail connecting plate 3213, and a tail transition block 3214. The output end of the tail suction cup cylinder 3212 is connected to the tail suction cup 3211 via the tail connecting plate 3213 and the tail transition block 3214. The tail glue preparation device 323 is connected to the tail suction cup 3211 and the tail glue pressing device 322 via adhesive tape.

[0064] The tail glue pressing device 322 is used to cut the tape covering the tail rubber coating. It includes a tail glue pressing cylinder 3221 and a tail cutter 3222. The tail cutter 3222 is located on one side of the tail suction cup 3211, and the output end of the tail glue pressing cylinder 3221 is connected to the tail cutter 3222. The tail glue preparation device 323 is used to transport and cut the tape covering the tail rubber coating. Its structure is the same as that of the head glue preparation device 123.

[0065] During operation of the tail glue wrapping mechanism 32, the tail glue preparation device 323 conveys the tape to the tail glue suction device 321 and the tail glue pressing device 322. Once the tape is fully in place, the tail glue pressing cylinder 3221 uses the tail cutter 3222 to cut one end of the tape, while the cylinder in the tail glue preparation device 323 uses the cutter to cut the other end of the tape. The cut tape is then attached to the tail suction cup 3211. The tail suction cup cylinder 3212 then drives the tail suction cup 3211 to press against the battery cell via the tail connecting plate 3213 and the tail transition block 3214, wrapping the tape around the tail of the cell.

[0066] The tail glue rolling mechanism 33 is used to roll the tail glue of the battery cell flat. Figure 7 As shown, the tail glue rolling mechanism 33 includes a tail glue rolling cylinder 331, a tail glue rolling connecting plate 332, a first tail roller 333, and a second tail roller 334. The first tail roller 333 and the second tail roller 334 are installed with a spacing between them. The output end of the tail glue rolling cylinder 331 is connected to the first and second tail rollers 333, 334 via the tail glue rolling connecting plate 332. After the tail glue coating of the battery cell is delivered to the next workstation, the tail glue rolling cylinder 331 controls the position of the first and second tail rollers 333, 334 via the tail glue rolling connecting plate 332. The first and second tail rollers 333, 334 clamp the battery cell, thereby pressing the tail glue coating of the battery cell against the surface of the cell.

[0067] During the operation of the entire battery cell encapsulation system, the battery cell is loaded through the head battery cell removal mechanism 11 and enters the first station of the sequence transfer mechanism 14. The turntable motor drives the sequence transfer mechanism 14 to rotate counterclockwise to send the battery cell to the second station. The head encapsulation mechanism 12 encapsulates the battery cell head with glue, and the head glue preparation device 123 transports the tape to the head glue suction device 121 and the head glue pressing device 122. When the tape is completely in place, the head glue pressing cylinder 1221 cuts off one end of the tape through the head cutter 1222, and the head glue preparation cylinder 1234 cuts off the other end of the tape through the head glue preparation cutter. The cut tape is adsorbed on the head suction cup 1211. At this time, the head suction cup cylinder 1212 drives the head suction cup 1211 to press against the battery cell through the head connecting plate 1213 and the head transition block 1214, so that the tape can be wrapped around the head of the battery cell. After the head glue wrapping is completed, the transfer mechanism 14 sends the battery cell to the third station, and the roller in the head glue winding mechanism 13 presses the battery cell head glue wrapping, that is, the battery cell head glue wrapping is completed, and the transfer mechanism 14 sends the battery cell to the fourth station. The side battery cell removal mechanism 21 transfers the battery cell from the fourth station to the side glue wrapping mechanism 22. The side glue preparation device 223 transports the tape to the side glue suction device 221 and the side glue pressing device 222. When the tape is completely in place, the side glue pressing cylinder 2221 cuts off one end of the tape through the side cutter 2222, and the cylinder in the side glue preparation device cuts off the other end of the tape through the cutter. The cut tape is adsorbed on the side suction cup 2211. At this time, the side suction cup cylinder 2212 drives the side suction cup 2211 to press against the battery cell through the side connecting plate 2213 and the side transition block 2214, so that the tape can be wrapped on the side of the battery cell. Then the side battery cell removal mechanism 21 transfers the battery cell from the side glue wrapping mechanism 22 to the side glue rolling mechanism 23. The side glue rolling cylinder 231 controls the position of the first side roller 233 and the second side roller 234 through the side glue rolling connecting plate 232, and uses the first side roller 233 and the second side roller 234 to clamp the battery cell, thereby pressing the glue on the side of the battery cell onto the surface of the battery cell. The tail battery cell removal mechanism 31 transfers the battery cell to the tail glue wrapping mechanism 32, and the tail glue preparation device 323 transports the tape to the tail glue suction device 321 and the tail glue pressing device 322. When the tape is completely in place, the tail glue pressing cylinder 3221 cuts off one end of the tape through the tail cutter 3222, and the cylinder in the tail glue preparation device 323 cuts off the other end of the tape through the cutter. The cut tape is adsorbed on the tail suction cup 3211. At this time, the tail suction cup cylinder 3212 drives the tail suction cup 3211 to press toward the battery cell through the tail connecting plate 3213 and the tail transition block 3214, so that the tape can be wrapped around the tail of the battery cell.The tail cell removal mechanism 31 then transfers the cell to the tail glue rolling mechanism 33. The tail glue rolling cylinder 331 controls the positions of the first and second tail rollers 333, 334 via the tail glue rolling connecting plate 332. The first and second tail rollers 333, 334 clamp the cell, pressing the glue coating at the tail of the cell against the cell surface. This completes the entire glue coating process for the cell.

[0068] To sum up, the battery cell encapsulation system provided by the present invention sequentially arranges a head encapsulation component, a side encapsulation component and a tail encapsulation component along the processing direction, and sequentially encapsulates the head, side and tail of the battery cell, thereby realizing the automated production of battery cell encapsulation and meeting various encapsulation requirements of the battery cell. In addition, the battery cell encapsulation system is provided with a head battery cell removing mechanism, a head encapsulation mechanism, a head encapsulation mechanism and a sequence transfer mechanism in the head encapsulation component, and utilizes multiple stations of the sequence transfer mechanism to realize the encapsulation of the head of the battery cell and operations such as loading and unloading, thereby realizing the coordinated processing of multiple components and multiple stations and ensuring the processing efficiency of the battery cell.
