Description

Technical Field

[0001] This utility model belongs to the field of battery formation venting technology, and in particular relates to a soft-pack battery formation venting device. Background Technology

[0002] Pouch cells are a commonly used type of rechargeable battery. After liquid injection and encapsulation, pouch cells require formation and other processes to activate them by applying electricity. Currently, the formation of pouch cells involves placing multiple cells in the same formation fixture, which then presses the cells together and connects them to a formation power source.

[0003] For example, Chinese invention patent document CN103811816B discloses a lithium-ion battery hot and cold pressing formation equipment, which includes a frame, a feeding tray, a hot pressing formation fixture, a cold pressing fixture, a discharging tray, a robot arm, and a formation cabinet. The feeding tray, hot pressing formation fixture, cold pressing fixture, discharging tray, and robot arm are all mounted on the frame. The formation cabinet is electrically connected to the hot pressing formation fixture. Both the cold pressing fixture and the hot pressing formation fixture include a shelf. The shelf contacts the battery and the angle between its contact surface and the horizontal plane is 90°±0.5°. Preferably, the shelf contacts the battery and the angle between its contact surface and the horizontal plane is 90°. The layers of the cold-press fixture and the hot-press forming fixture do not overlap in the horizontal plane, facilitating battery gripping by a standard robotic arm. Even when the robotic arm can grip the battery with overlapping projections of the layers of the cold-press fixture and the hot-press forming fixture, their horizontal projections can still be set to overlap. The robotic arm grips batteries in one go, transferring them between the loading tray, the hot-press forming fixture, the cold-press fixture, and the unloading tray. Within the equipment, the loading tray, the hot-press forming fixture, the cold-press fixture, and the unloading tray remain stationary. The batteries circulate among the various fixtures under the robotic arm's control, avoiding the problem of handling heavy fixtures. The robotic arm can remove batteries from the fixtures or trays in one go, saving time on battery loading and unloading, resulting in high battery transfer efficiency. The robotic arm grabs all the lithium-ion batteries from the loading tray at once and places them directly into the hot-pressing formation fixture. After the lithium-ion batteries complete the hot-pressing formation in the hot-pressing formation fixture, the robotic arm grabs all the lithium-ion batteries from the hot-pressing formation fixture at once and places them directly into the cold-pressing fixture. After the lithium-ion batteries complete the cold-pressing and shaping in the cold-pressing fixture, the robotic arm grabs all the lithium-ion batteries from the cold-pressing fixture at once and places them directly into the unloading tray.

[0004] The aforementioned patent documents disclose a technical solution that achieves simultaneous formation using multiple clamps and automates the process. Because gas is generated during the pressure formation of pouch batteries, the internal pressure of the pouch battery packaging bag becomes high, causing bulging. Therefore, it is necessary to release the gas inside the battery to relieve the pressure. To address this technical problem, Chinese utility model patent document CN208256834U discloses a pouch lithium battery formation degassing device, including a formation clamp. A guide rail seat is provided at the upper end of one side of the formation clamp, and a guide rail is provided on the guide rail seat. A driving mechanism drives a slide to slide along the guide rail. A flipping mechanism or lifting mechanism provided on the slide seat drives a puncture degassing mechanism to flip or move up and down, securing it to both sides of the pouch lithium battery. The puncture degassing mechanism includes a mounting base, a first mounting arm, a second mounting arm, and a power mechanism that drives the first and second mounting arms to move in opposite directions, located at the free end of the first mounting arm. The inner side has a needle and a first elastic suction cup, and the needle sleeve and the second elastic suction cup are located inside the free end of the second mounting arm. The needle is located in the cavity of the first elastic suction cup, and the needle sleeve is located in the cavity of the second elastic suction cup. The first mounting arm and / or the second mounting arm are provided with a suction hole connected to the negative pressure system pipeline. When the first mounting arm and the second mounting arm are locked on both sides of the battery, the power mechanism pushes the first mounting arm and the second mounting arm to move towards each other. The needle and the needle sleeve cooperate to punch a hole in the battery air bag area, and the first elastic suction cup and the second elastic suction cup are attached to both sides of the battery. After the negative pressure system discharges the gas in the battery through the suction hole, the sealing mechanism seals the hole. When the battery is placed into the formation fixture for formation, after a certain period of time, the drive mechanism drives the slide to slide along the guide rail. A flipping mechanism or lifting mechanism positions the first and second mounting arms on either side of the first battery. A power mechanism pushes the first and second mounting arms to move towards each other. A needle and needle sleeve work together to punch an air hole in the battery bag. The first and second elastic suction cups adhere to both sides of the battery. A negative pressure system extracts the gas from the battery through the air extraction hole, and a sealing mechanism seals the air hole. After the gas is generated inside the first lithium battery, the drive mechanism pushes the slide downwards, thus venting the second lithium battery. This process continues, continuously venting the gas inside the battery. Therefore, the volume of the packaging bag can be reduced, thereby reducing the amount of raw materials needed for the packaging bag and lowering the cost of the lithium battery.

[0005] The technical solution disclosed in the aforementioned Chinese utility model patent document CN208256834U solves the problem of venting gas during battery formation. However, the reciprocating movement of a set of formation venting devices to puncture, vent, and heat-seal the battery one by one is inefficient and cannot meet the needs of large-scale automated production. Furthermore, in the technical solution of this patent document, the needle sleeve and piercing needle are positioned in the middle of the heating sleeve. Although there is a heat insulation sleeve, the temperature of the needle sleeve and piercing needle still rises. Therefore, when the needle sleeve and piercing needle work together to puncture the bag, the high temperature of the needle sleeve and piercing needle causes fusion at the puncture site, resulting in the bag being punctured but unable to release gas, thus causing an unstable gas discharge problem.

[0010] Furthermore, the mounting bracket is provided with a manifold, each of the suction cups is connected to the manifold, and the manifold is connected to the puncture and suction mechanism.

[0011] Furthermore, the mounting bracket is provided with equidistant moving mechanisms on both sides, each having multiple mounting positions for mounting the puncture extraction mechanism or the heat sealing mechanism.

[0012] The equidistant moving mechanism includes a guide rail, an adjusting screw, a motor, scissor arm linkages, and connecting seats. The guide rail is located on one side of the mounting frame, and multiple sets of connecting seats are slidably connected to the guide rail. The connecting seats are used to install the puncture and suction mechanism or the heat sealing mechanism. Multiple sets of scissor arm linkages are connected in sequence to form a folding mechanism.

The adjusting screw is located at one end of the mounting frame. The scissor arm linkage near the adjusting screw is provided with a nut for connecting to the adjusting screw, and the end of the scissor arm linkage away from the adjusting screw is fixed.

[0021] This utility model's soft-pack battery formation venting device is positioned above the formation fixture. When the battery within the formation fixture needs venting, a lifting mechanism drives the mounting frame to descend, positioning the two first clamping plates of the puncture and suction mechanism on either side of a battery. A first driving component drives the two first clamping plates to clamp each other, allowing the suction cup to adhere to the outside of the battery. With the cooperation of the puncture needle and needle sleeve, the battery pouch is punctured. The suction device then creates negative pressure on the suction cup, venting the gas inside the battery. Because multiple puncture and suction mechanisms are installed on the mounting frame, multiple batteries can be punctured and vented simultaneously, improving efficiency. After venting is complete, the connecting frame moves as a whole, moving the two second clamping plates of the heat-sealing mechanism to the sides of the corresponding battery, positioning the heat-sealing plate at the puncture site. A second driving component drives the two second clamping plates to clamp each other, causing the heat-sealing plate to heat-seal the puncture site. Simultaneous heat sealing by multiple mechanisms results in high heat-sealing efficiency. In addition, since the puncture needle and needle sleeve are separate from the heat-sealing plate, the problem of the puncture opening being fused together is avoided when the puncture needle and needle sleeve work together to puncture the battery bag.

[0036] In one embodiment of the soft-pack battery formation venting device of this utility model, please refer to... Figure 1 and Figure 2 A pouch battery formation venting device is used to vent the battery within the formation fixture on a battery formation device. Specifically, the pouch battery formation venting device includes a connecting frame 100, a lifting mechanism 200, a mounting frame 300, a puncture and extraction mechanism 400, and a heat sealing mechanism 500. The lifting mechanism 200 is located on the bottom side of the connecting frame 100, and the mounting frame 300 is connected to the lifting mechanism 200; therefore, the lifting mechanism 200 can drive the mounting frame 300 to move up and down. Preferably, the lifting mechanism 200 is a lead screw module. Multiple puncture and extraction mechanisms 400 are arranged on one side of the mounting frame 300, and multiple heat sealing mechanisms 500 are located on the other side of the mounting frame 300.

[0037] Reference Figures 3 to 7 The puncture suction mechanism 400 includes two first clamping plates 410 and a first driving member 420. The two first clamping plates 410 are connected to the first driving member 420, and the first driving member 420 drives the two first clamping plates 410 to move closer or further apart. Preferably, the first driving member 420 can be a pneumatic parallel clamp. The first driving member 420 is connected to one side of the mounting bracket 300. Suction cups 430 are provided on opposite sides of the two first clamping plates 410. The suction cups 430 are connected to a suction device (as shown in the attached figure). A puncture needle 440 is provided in one suction cup 430, and a needle sleeve 450 is provided in the other suction cup 430.

[0038] Reference Figure 5 The heat-sealing mechanism 500 includes a second clamping plate 510 and a second driving member 520. The two second clamping plates 510 are connected to the second driving member 520, which drives the two second clamping plates 510 to clamp each other or move away from each other. Preferably, the second driving member 520 can be a pneumatic parallel clamp. A heat-sealing plate 530 is provided on the opposite sides of the two second clamping plates 510. Furthermore, a temperature sensor is also provided inside the heat-sealing plate 530 to detect the temperature inside the heat-sealing plate 530, thereby enabling precise control of the temperature of the heat-sealing plate 530.

[0039] In this embodiment, the soft-pack battery formation venting device is positioned above the formation fixture. When the battery within the formation fixture needs venting, the lifting mechanism 200 drives the mounting frame 300 to descend, positioning the two first clamping plates 410 of the puncture and suction mechanism 400 on either side of a battery. The first driving member 420 drives the two first clamping plates 410 to clamp each other, allowing the suction cup 430 to adhere to the outside of the battery. With the cooperation of the puncture needle 440 and the needle sleeve 450, the battery pouch can be punctured. The suction device then creates a negative pressure on the suction cup 430, venting the gas inside the battery. Because multiple puncture and suction mechanisms 400 are provided on the mounting frame 300, multiple batteries can be punctured and vented simultaneously, improving efficiency. A connecting frame connects to a translation device; after the battery venting is completed, the connecting frame 100 moves as a whole, causing the two second clamping plates 510 of the heat-sealing mechanism 500 to move to the sides of the corresponding battery, and positioning the heat-sealing plate 530 at the puncture site. The second driving component 520 drives the two second clamping plates 510 to clamp each other, and the two heat sealing plates 530 heat the battery packaging bag to heat seal the puncture opening; and multiple heat sealing mechanisms 500 simultaneously perform heat sealing, resulting in high heat sealing efficiency. In addition, since the puncture needle 440 and needle sleeve 450 are separate from the heat sealing plate 530, the problem of the puncture opening being fused together is avoided when the puncture needle 440 and needle sleeve 450 work together to puncture the battery bag.

[0040] Furthermore, refer to Figure 1 , Figure 2 and Figure 3 The mounting bracket 300 is equipped with a manifold 301, and each suction cup 430 is connected to the manifold 301. The manifold 301 is connected to the puncture and suction mechanism. The manifold 301 connects each suction cup 430 and the puncture and suction mechanism, thus facilitating the connection between the suction cup 430 and the puncture and suction mechanism.

[0041] Furthermore, refer to Figure 3 , Figure 4 , Figure 5 and Figure 9 The mounting bracket 300 is further provided with equidistant moving mechanisms 600 on both sides. Each equidistant moving mechanism 600 has multiple mounting positions, each for mounting a set of puncture-extraction mechanisms 400 or heat-sealing mechanisms 500. Specifically, one set of equidistant moving mechanisms 600 mounts the puncture-extraction mechanisms 400, while the other set mounts the heat-sealing mechanisms 500. Therefore, the spacing between adjacent puncture-extraction mechanisms 400 and the spacing between heat-sealing mechanisms 500 can be adjusted by the equidistant moving mechanisms 600.

[0042] Specifically, refer to Figure 3 , Figure 4 , Figure 5 and Figure 9The equidistant moving mechanism 600 includes a guide rail 610, an adjusting screw 620, a motor 630, scissor arm connecting rods 640, and a connecting seat 650. The guide rail 610 is located on one side of the mounting frame 300. Multiple sets of connecting seats 650 are slidably connected to the guide rail 610, and are used to mount the puncture suction mechanism 400 or the heat sealing mechanism 500. Multiple sets of scissor arm connecting rods 640 are sequentially connected to form a folding mechanism. The connection points of adjacent scissor arm connecting rods 640 form mounting positions and are connected to the corresponding connecting seats 650. The adjusting screw 620 is located at one end of the mounting frame 300. The scissor arm connecting rods 640 near the adjusting screw 620 have nuts for connecting to the adjusting screw 620, while the ends of the scissor arm connecting rods 640 away from the adjusting screw 620 are fixed. The motor 630 is connected to the adjusting screw 620 and is used to drive the adjusting screw 620 to rotate. In this embodiment, when adjusting the spacing between the puncture extraction mechanism 400 or the heat sealing mechanism 500, the motor 630 drives the adjusting screw 620 to rotate. Under the action of the nut on the adjusting screw 620, the scissor arm connecting rod 640 is pushed to extend and retract, thereby driving all the scissor arm connecting rods 640 to adjust in a coordinated manner, thus adjusting the spacing of the mounting position. Therefore, the soft-pack battery formation venting device of this embodiment can realize the formation venting of batteries of different thicknesses.

[0043] Furthermore, refer to Figure 1 and Figure 2 The mounting bracket 300 is equipped with lifting mechanisms 700 on both sides, and equidistant moving mechanisms 600 are connected to the corresponding lifting mechanisms 700, so that the lifting mechanisms 700 drive the corresponding equidistant moving mechanisms 600 to move up and down. In this embodiment, when the battery bag is punctured or the puncture opening is heat-sealed, the lifting mechanism 700 drives the first clamping plate 410 or the second clamping plate 510 to rise or fall. Specifically, the lifting mechanism 700 can be a cylinder, an electric linear module, etc.

[0044] Furthermore, refer to Figure 1 and Figure 2 The mounting bracket 300 is further equipped with translation mechanisms 800 on both sides, which are connected to the lifting mechanism 700. An equidistant moving mechanism 600 is mounted on the translation mechanism 800. In this embodiment, the translation mechanism 800 can drive the equidistant moving mechanism 600 to translate. Therefore, when the battery thickness is thin, the equidistant moving mechanism 600 can adjust the spacing of the puncture and extraction mechanisms 400, and another equidistant moving mechanism 600 can adjust the spacing of the heat-sealing mechanisms 500. The translation mechanism 800 can also adjust the position of the mounting bracket 300, allowing the puncture and extraction mechanisms 400 to puncture and extract air from the battery at intervals. This avoids the problem of the puncture and extraction mechanisms 400 being too close together and interfering with each other.

[0045] Furthermore, refer to Figure 3 and Figure 4The translation mechanism 800 has a guide rail seat 810 on its movable seat, and a guide rail 610 is mounted on the guide rail seat 810. The guide rail seat 810 has a mounting groove, and the scissor arm connecting rod 640 is located in the mounting groove.

[0046] Furthermore, refer to Figure 8 The lower ends of the two first clamping plates 410 on opposite sides are also provided with air suction connectors 460, and suction cups 430 are fitted onto air suction connectors 460. One air suction connector 640 is provided with a piercing needle 440, and the other air suction connector 460 is provided with a needle sleeve 450; air suction connectors 460 are connected to air suction devices.

[0047] Furthermore, the suction connector 460 is provided with a slot 461 and an air groove 462, and an air hole 463 is provided on the end side of the suction connector 460, extending to the air groove 462. The suction cup 430 is engaged in the slot 461; the first clamping plate 410 is provided with a mounting hole, and the suction connector 460 is installed in the mounting hole. Specifically, a screw hole is provided at the end of the suction connector 460, and a locking screw passes through the first clamping plate 410 and connects to the screw hole. An air passage 464 communicating with the air groove 462 is provided in the first clamping plate 410, and the air passage 464 extends to the upper end of the first clamping plate 410. In this embodiment, the air passage 464 extends to the upper end of the first clamping plate 410, thus facilitating the connection of the air pipe and avoiding interference between the air pipe and the clamping of the first clamping plate 410.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
