Description

Technical Field

[0001] This invention relates to the field of battery packaging technology, and in particular to a fully automatic battery packaging machine. Background Technology

[0002] In the production process of soft-pack batteries, a battery packaging machine is generally used to encapsulate the battery cells into a battery casing made of aluminum-plastic film. Some existing packaging processes first punch and trim the aluminum-plastic film battery casing before feeding it to the battery packaging machine. The battery packaging machine then sequentially completes the following steps: feeding the battery cells, folding the battery casing in half, top sealing, side sealing, trimming the battery casing, and unloading the finished product. However, since the battery casing is pre-trimmed based on the theoretical folding position, there is often an error between the actual folding position and the theoretical folding position when folding the battery casing to package the battery cells. This results in uneven edges at both ends of the battery casing after folding to package the battery cells, affecting the product's appearance and quality. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a fully automatic battery packaging machine, which can first close the mold and fold the battery shell, then cut the edges of the battery shell, and then close the mold again to package the battery cell, ensuring that the two ends of the cut battery shell are flush with the edges after packaging the battery cell, thus ensuring the product appearance and product quality.

[0004] An automatic battery packaging machine according to an embodiment of the present invention includes a frame, a turntable, a trimming mechanism, a cell loading mechanism, a top sealing mechanism, and a side sealing mechanism. The turntable is rotatably mounted on the frame. The frame is provided with a first driving mechanism for driving the turntable to rotate. A mold clamping fixture is provided on the turntable. The turntable can sequentially transport the mold clamping fixture to a battery casing loading station, a mold clamping and trimming station, a cell packaging station, a first packaging station, a second packaging station, and a unloading station provided on the frame. The mold clamping fixture includes a lower mold and an upper mold. A second driving mechanism is provided between the turntable or the turntable and the frame. The second driving mechanism is used to drive the lower mold and the upper mold to rotate relative to each other and move closer or further apart. The clamping fixture is configured to close or open the mold, and both the upper and lower molds of the fixture are equipped with adsorption devices for adsorbing and fixing the battery casing, so that the clamping fixture can fold or open the battery casing when closing or opening the mold; the trimming mechanism is located at the clamping trimming station, and the trimming mechanism is used to trim the battery casing on the clamping fixture when the clamping fixture at the clamping trimming station is in the closed state; the cell loading mechanism is located at the cell packaging station, and the cell loading mechanism is used to cooperate with the clamping fixture and the second driving mechanism to package the cell into the battery casing; one of the top sealing mechanism and the side sealing mechanism is located at the first packaging station, and the other is located at the second packaging station.

[0005] According to an embodiment of the present invention, a fully automatic battery packaging machine has at least the following beneficial effects: The fully automatic battery packaging machine provided by the present invention can load battery casings at the battery casing loading station, trim the battery casings at the mold closing and trimming station, open the mold and load the battery cells at the cell packaging station, close the mold to complete the initial packaging of the battery cells, and then the top sealing mechanism and the side sealing mechanism complete the top sealing and side sealing processes. Finally, the packaged product is unloaded. In the mold closing and trimming station, when trimming the battery casings, the mold closing fixture is in the mold closing state, that is, the mold closing fixture closes the mold to fold the battery casings in half before trimming the battery casings. Since the folding position of the battery casings remains basically unchanged when folded once and then folded again, it can be ensured that the two ends of the trimmed battery casings are flush with the edges after packaging the battery cells, ensuring the product appearance and improving product quality. In addition, since the battery casings are trimmed before the battery cells are packaged, the top sealing mechanism and the side sealing mechanism can be used to correct the edge deformation of the battery casings caused by trimming during packaging.

[0006] According to some embodiments of the present invention, the frame is provided with a pressing station, which is located between the battery casing loading station and the mold closing and trimming station.

The slider is slidably mounted on the frame, the clutch lifting device is mounted on the slider, the motor is mounted on the frame and is drivenly connected to the lead screw, the lead screw is drivenly connected to the slider, and the motor can drive the slider to slide through the lead screw.

[0032] Reference Figures 1 to 3According to an embodiment of the present invention, a fully automatic battery packaging machine includes a frame 110, a turntable 120, a trimming mechanism 170, a cell loading mechanism 130, a top sealing mechanism 140, and a side sealing mechanism 150. The turntable 120 is rotatably mounted on the frame 110. The frame 110 is provided with a first driving mechanism (not shown in the figure) for driving the turntable 120 to rotate. A mold clamping fixture 160 is provided on the turntable 120. The turntable 120 can sequentially transport the mold clamping fixture 160 to the battery casing loading station 01, the mold clamping and trimming station 03, the cell packaging station 04, the first packaging station 05, the second packaging station 06, and the unloading station 07 provided on the frame 110. The mold clamping fixture 160 includes a lower mold 161 and an upper mold 162. A second driving mechanism is provided between the turntable 120 or the turntable 120 and the frame 110. The second driving mechanism is used to drive the fixture. The lower mold 161 and the upper mold 162 of the clamp rotate relative to each other to move closer or further apart to realize the mold closing fixture 160 closing or opening. Both the upper mold 162 and the lower mold 161 of the clamp are provided with adsorption devices (not shown in the figure) for adsorbing and fixing the battery shell, so that the mold closing fixture 160 can drive the battery shell to fold or open when closing or opening the mold. The edge trimming mechanism 170 is provided at the mold closing edge trimming station 03. The edge trimming mechanism 170 is used to trim the battery shell on the mold closing fixture 160 when the mold closing fixture 160 is in the mold closing state at the mold closing edge trimming station 03. The cell loading mechanism 130 is provided at the cell packaging station 04. The cell loading mechanism 130 is used to cooperate with the mold closing fixture 160 and the second drive mechanism to package the cell into the battery shell. One of the top sealing mechanism 140 and the side sealing mechanism 150 is provided at the first packaging station 05, and the other is provided at the second packaging station 06.

[0033] The fully automatic battery packaging machine provided by this invention can load battery casings at the battery casing loading station 01, trim the battery casings at the mold closing and trimming station 03, and first open the mold to load the battery cells at the cell packaging station 04, then close the mold to complete the initial packaging of the battery cells. The top sealing mechanism 140 and the side sealing mechanism 150 then complete the top sealing and side sealing processes. Finally, the packaged product is unloaded. In this fully automatic battery packaging machine, when trimming the battery casings at the mold closing and trimming station 03, the mold closing fixture 160 is in a closed state, i.e., when the mold closing fixture 160 is closed... The mold folds the battery casing in half and then trims its edges. At this point, the edges of both ends of the battery casing are aligned. Since the folding position of the battery casing remains essentially unchanged after folding once and then folding again, it ensures that the edges of the trimmed battery casing are flush after the battery cells are packaged, guaranteeing product appearance and improving product quality. Furthermore, trimming the battery casing before battery cell packaging allows the top sealing mechanism 140 and side sealing mechanism 150 to correct any edge deformation caused by trimming during packaging, ensuring product appearance and improving production quality. In addition, since the mold clamping fixture 160 is in the closed state during trimming, it effectively prevents waste generated during trimming from entering the recessed areas of the battery casing, thus preventing waste from damaging the battery casing or battery cells during subsequent battery cell packaging, top sealing, and side sealing, ensuring product quality.

[0034] Typically, continuous production uses a rotary table 120 to transport workpieces, allowing different workpieces to undergo corresponding processes simultaneously at different workstations. Therefore, the overall efficiency of continuous production is determined by the process that takes the longest. The fully automatic battery packaging machine provided by this invention performs two folds of the battery casing before top and side sealing. During the first fold, the battery cell is not placed inside the casing, making the first fold easier and faster. Even if the first fold leaves a crease, the second fold can be performed along this crease, ensuring both speed and accuracy. Thus, at the cell packaging station 04, the initial cell packaging is completed through mold opening, cell loading, and the second mold closing and folding of the battery casing. Both mold opening and the second mold closing and folding are completed quickly. Therefore, although the fully automatic battery packaging machine provided by this invention adds mold closing and edge trimming processes before cell packaging, it reduces the time required for initial cell packaging, thus improving the overall efficiency of continuous production.

[0035] Reference Figures 1 to 3According to some embodiments of the present invention, the frame 110 is provided with a molding station 02, which is located between the battery casing loading station 01 and the mold closing and trimming station 03. The molding station 02 is provided with a molding mechanism 300, which is used to press the battery casing on the mold closing fixture 160 when the mold closing fixture 160 at the molding station 02 is in the open state, so that the battery casing is tightly fitted with the upper mold 162 and the lower mold 161 of the fixture, thereby reducing the wrinkles generated during the folding process of the battery casing and improving the folding accuracy of the battery casing. After molding is completed, the mold closing fixture 160 can be closed for the first time at the molding station 02 to fold the battery casing for the first time. Thus, when the mold closing fixture 160 reaches the mold closing and trimming station 03, it is in the closed state, and the trimming mechanism 170 can be used directly to trim the battery casing, thereby improving production efficiency.

[0036] Reference Figures 1 to 3 According to some embodiments of the present invention, the mold clamping fixture 160 is provided with at least 7 fixtures that are circumferentially distributed around the rotation axis of the turntable 120. In the continuous production process, the battery casing loading station 01, the mold clamping and trimming station 03, the cell packaging station 04, the first packaging station 05, the second packaging station 06, and the unloading station 07 can all reach one mold clamping fixture 160 at the same time, so as to realize that different products can perform different processes at different stations at the same time, thereby improving production efficiency.

[0037] Reference Figures 1 to 3 According to some embodiments of the present invention, the second drive mechanism includes at least seven transmission components 210 and two mold-closing drive devices 220. All transmission components 210 are disposed on the turntable 120 and are connected to all mold-closing fixtures 160 in a one-to-one transmission connection. The two mold-closing drive devices 220 are respectively disposed at the film pressing station 02 and the battery cell packaging station 04. Each mold-closing drive device 220 is provided with a clutch 230, which is used to control whether the mold-closing drive device 220 is connected to the transmission components 210 that have moved to the mold-closing drive device 220. With the above configuration, only two mold-closing drive devices 220 are needed to meet the working requirements, eliminating the need to configure a mold-closing drive device 220 for each mold-closing fixture 160. This simplifies the structure of the second drive mechanism, reduces costs, and simplifies the control system.

[0038] Reference Figure 2In the specific implementation process, the frame 110 is also equipped with a reserved station 08. At this time, there are 8 mold clamping fixtures 160. Thus, the battery casing loading station 01, the film pressing station 02, the mold clamping and trimming station 03, the cell packaging station 04, the first packaging station 05, the second packaging station 06, the unloading station 07, and the reserved station 08 can be evenly arranged in a circle around the turntable 120. In this way, the area of ​​the frame 110 around the turntable 120 can be divided into eight equal parts, and each station is set in one of the eight partitions. Among them, dividing into eight equal parts is easier to achieve than dividing into seven equal parts, thereby reducing the difficulty of layout.

[0039] Reference Figure 1 and Figure 3 According to some embodiments of the present invention, the mold closing drive device 220 is located below the turntable 120, and the clutch 230 includes a clutch lifting device 231 mounted on the mold closing drive device 220 and a clutch connector 232 mounted on the clutch lifting device 231. The transmission assembly 210 is connected to a connector 213 for mating with the clutch connector 232, and the turntable 120 can drive the connector 213 to move above the clutch connector 232. With the above configuration, the clutch 230 has a simple structure and reliable operation.

[0040] Reference Figure 3 According to some embodiments of the present invention, the transmission assembly 210 includes a gear 211 rotatably mounted on the turntable 120 and a rack 212 slidably mounted on the turntable 120. The rack 212 meshes with the gear 211 for transmission. The upper mold 162 of the fixture is connected to the gear 211. The rack 212 is fixedly connected to the connector 213. When the clutch connector 232 is engaged with the connector 213, the mold closing drive device 220 can drive the rack 212 to slide through the clutch 230. In turn, the rack 212 drives the gear 211 to drive the upper mold 162 of the fixture to rotate relative to the lower mold 161 of the fixture. With the above configuration, the rotation of the upper mold 162 of the fixture can be precisely controlled to ensure the mold closing accuracy.

[0041] Reference Figure 3 According to some embodiments of the present invention, the mold clamping drive device 220 includes a motor 221, a lead screw (not shown in the figure), and a slider 222. The slider 222 is slidably mounted on the frame 110, and a clutch lifting device 231 is mounted on the slider 222. The motor 221 is mounted on the frame 110 and is driven by the lead screw. The lead screw is driven by the slider 222, and the motor 221 can drive the slider 222 to slide through the lead screw. With the above configuration, the mold clamping drive device 220 has high working accuracy and can accurately control the rotation of the upper mold 162 of the fixture.

[0042] In other embodiments, the transmission assembly 210 may be configured in other ways. For example, the transmission assembly 210 may include a gear 211 and a transmission shaft. The transmission shaft is vertically rotatably mounted on the turntable 120 and meshes with the gear 211. The gear 211 is rotatably mounted on the turntable 120 and connected to the upper mold 162 of the fixture. In this case, the mold closing drive device 220 may include a servo motor, and the clutch 230 includes a clutch connector 232, which is slidably sleeved on the output shaft of the servo motor. The output shaft of the servo motor is provided with a protrusion, and the clutch connector 232 is provided with a slot. The upper side wall of the slot is provided with a clutch groove. The side wall of the clutch groove is inclined. The protrusion can move between the slot and the clutch groove. When the protrusion enters the slot from the clutch groove, it can drive the clutch connector 232 to rise so that the clutch connector 232 can be inserted into the lower end of the drive shaft. When the protrusion abuts against the side wall of the slot, the protrusion can drive the clutch connector 232 to rotate, and then the clutch connector 232 can drive the drive shaft to rotate.

[0043] It is conceivable that in other embodiments, the second drive mechanism described above may also be configured in other ways. For example, the second drive mechanism may be configured on the turntable 120. In this case, the second drive mechanism includes a transmission component 210 that is connected to the mold clamping fixture 160 and a linear driver that is connected to the transmission component 210.

[0044] Reference Figure 3 According to some embodiments of the present invention, the molding mechanism 300 includes a moving platform 310 and a pressure plate 320. The moving platform 310 is installed at the molding station 02, and the pressure plate 320 is installed on the moving platform 310. The pressure plate 320 is inclined, so that the moving platform 310 can drive the pressure plate 320 to move and press against the battery casing located at the molding station 02, so that the battery casing is tightly attached to the upper mold 162 and the lower mold 161 of the fixture, thereby improving the molding quality.

[0045] Reference Figure 3 In specific implementation, the mobile platform 310 may include a first mobile device 311 and a second mobile device 312. The second mobile device 312 is mounted on the first mobile device 311, and the pressure plate 320 is disposed on the second mobile device 312. The first mobile device 311 is used to tilt and drive the second mobile device 312 to move and lift. The second mobile device 312 is used to drive the pressure plate 320 to move in a direction perpendicular to the moving direction of the second mobile device 312. The first mobile device 311 and the second mobile device 312 may be configured as cylinders or linear motors, etc.

[0046] Reference Figure 1 and Figure 4According to some embodiments of the present invention, a corner sealing unloading mechanism 400 is provided at the unloading station 07. The corner sealing unloading mechanism 400 is used to press the corners of the packaged battery before unloading it, so as to supplement the sealing of the corners of the battery casing, avoid the corners of the battery casing from being poorly sealed, and improve the sealing quality.

[0047] Reference Figure 1 and Figure 4 The corner sealing and unloading mechanism 400 includes a lower corner sealing component 410, an upper corner sealing component 420, and an unloading conveying component 430. The upper corner sealing component 420 is disposed on the unloading conveying component 430. The unloading conveying component 430 moves the battery casing at unloading station 07 above the lower corner sealing component 410. Then, the upper corner sealing component 420 and the lower corner sealing component 410 can come together to clamp and press against the corners of the battery casing, thus achieving corner sealing. After corner sealing is completed, the unloading conveying component 430 transports the casing to downstream processes or equipment. With the above configuration, the corner sealing and unloading mechanism 400 can complete both corner sealing and unloading without the need for separate mechanisms for corner sealing and unloading, achieving a simplified structure.

[0048] Reference Figure 1 and Figure 7 According to some embodiments of the present invention, a receiving mechanism 500 is also included. The receiving mechanism 500 is disposed on one side of the corner sealing unloading mechanism 400. The receiving mechanism 500 is used to stack the batteries output by the corner sealing unloading mechanism 400 onto the material frame 530, thereby allowing the packaged batteries to be framed.

[0049] Reference Figure 7 In the specific implementation process, the receiving mechanism 500 includes a film packaging component 510 and a feeding frame device 520. The film packaging component 510 is used to package the battery with film, and the feeding frame device 520 is used to stack the packaged batteries in the material frame 530.

[0050] Reference Figure 8 and Figure 9 In some embodiments, the material frame 530 includes an outer frame 531 and an adjustable inner frame 532. The adjustable inner frame 532 is disposed inside the outer frame 531. The size of the adjustable inner frame 532 in the horizontal cross section can be adjusted to meet the stacking requirements of batteries of different sizes.

[0051] Reference Figure 8 and Figure 9Specifically, the adjustable inner frame 532 includes four vertically arranged corner brackets 5321. These four corner brackets 5321 are arranged in a rectangular shape to enclose a storage cavity for stacking batteries. The corner brackets 5321 are right-angled in horizontal cross-section. Adjusting rods 5322 are threaded through the upper and lower ends of each corner bracket 5321. The adjusting rods 5322 are slidably mounted on the outer frame 531, and the corner brackets 5321 can slide along their corresponding adjusting rods 5322. The sliding direction of the adjusting rods 5322 is perpendicular to the sliding direction of the corner brackets 5321, thereby allowing for horizontal adjustment of the storage cavity size. To simplify the structure, each adjusting rod 5322 is threaded through two corresponding corner brackets 5321, thus requiring only four adjusting rods 5322 to meet the usage requirements.

[0052] Reference Figure 8 and Figure 9 In some embodiments, the outer frame 531 is also slidably mounted with two limiting rods 533. The two limiting rods 533 are located on the upper side of the adjustable inner frame 532. The two limiting rods 533 can slide relative to each other to block above the adjustable inner frame 532, thereby pressing down on the batteries stacked inside the adjustable inner frame 532 and preventing the batteries from shaking and being damaged during transportation. The two limiting rods 533 can also slide relative to each other to avoid the adjustable inner frame 532.

[0053] Reference Figure 1 and Figure 5 According to some embodiments of the present invention, the fully automatic battery packaging machine further includes a battery casing punching and feeding mechanism 600. One end of the battery casing punching and feeding mechanism 600 is disposed at the battery casing feeding station 01. The battery casing punching and feeding mechanism 600 includes a roll unwinding device 620, a roll cutting device 630, a battery casing punching device 640, and a transfer device 650. The roll cutting device 630 is located between the roll unwinding device 620 and the battery casing punching device 640. The roll cutting device 630 is used to cut the roll supplied by the roll unwinding device 620 into a battery casing. The battery casing punching device 640 is used to punch holes in the battery casing. The transfer device 650 transports the punched battery casing to the battery casing feeding station 01. Among them, the battery casing punching device 640 can punch two indentations on the flat battery casing.
