Description

Technical Field

[0001] The present invention relates to the technical field of battery production equipment, and in particular to sodium ion battery packaging equipment. Background Art

[0002] Amid the rapid development of the new energy vehicle industry, sodium-ion batteries (Na-ion batteries) have become a key development direction in the power battery sector due to their low cost and abundant resource reserves. The quality of their packaging directly impacts vehicle safety and endurance. Currently, traditional battery packaging equipment suffers from low packaging efficiency and high costs. For example, the existing method of sealing batteries with adhesives not only places high demands on the adhesive's bonding position, quantity, and duration, resulting in high packaging costs, but also suffers from limited adhesive bonding capabilities, low overall packaging quality, and low packaging efficiency.

[0003] Although the existing patent (CN2187619687U) has improved some problems through heat sealing, it still has defects in packaging accuracy and equipment compatibility. For example, the adjustment method of the pre-tightening device of its clamp assembly is relatively simple. The first pre-tightening device and the second pre-tightening device in the upper clamp can only be adjusted on the positioning frame through the limit block at the output end. This adjustment method is difficult to achieve precise clamping force control when facing batteries of different thicknesses or sizes, which may cause the battery to be offset or damaged by over-clamping during the packaging process. In addition, the driving structure of the head assembly has insufficient adaptive adjustment capability of the heat sealing trajectory when facing changes in battery specifications. The first head and the second head are driven and moved by the third drive motor and the fourth drive motor, and can only move along the axis of the output shaft. When the diameter or height of the battery changes, it is difficult to flexibly adjust the heat sealing path, which may lead to differences in sealing uniformity when packaging batteries of different sizes, affecting the packaging quality.

[0004] Therefore, it is necessary to provide a sodium ion battery packaging device to solve the above technical problems. Summary of the Invention

[0008] A side wall rolling mechanism is installed on the machine base through the drive shaft. The side wall rolling mechanism includes a fixed bracket, and the fixed bracket is installed on the drive shaft.

Each limit frame is vertically installed with a guide rail, and a moving seat is slidably connected to the guide rail. The two parallel moving seats are commonly fixedly connected with a transverse locking frame, and the transverse locking frame is vertically arranged to the limiting frame. The two transverse locking frames are fixedly connected with end face locking seats, and the end face locking seats are connected by a central linkage assembly.

[0010] As a further solution of the present invention, the central linkage assembly includes a central rotating frame, and the central rotating frame is rotatably connected to the center position of the connecting honing plate. The two ends of the central rotating frame are connected to the transverse locking frame through a rotating frame. A pushing cylinder is provided on the connecting honing plate, and the piston rod end of the pushing cylinder is rotatably connected to one of the transverse locking frames.

[0033] Example 1

[0034] like Figures 1-9 As shown, a sodium ion battery packaging device includes a base 1, a truss 2 is provided on the base 1, and an electric slide rail 3 is vertically provided on the side wall of the truss 2.

[0035] like Figure 2-Figure 5As shown, the electric slide rail 3 is slidably connected with a clamping movement mechanism, and the clamping movement mechanism includes a sliding seat 4, the sliding seat 4 is slidably connected to the electric slide rail 3, and the sliding seat 4 is provided with a connecting honing plate 5, and two limit frames 6 are symmetrically installed on the connecting honing plate 5, and the two limit frames 6 are vertically arranged on the connecting honing plate 5, and each of the limit frames 6 is vertically installed with two guide rails 7, and each of the guide rails 7 is slidably connected with a moving seat 8, and the two parallel moving seats 8 are commonly fixedly connected with a transverse locking frame 9, and the transverse locking frame 9 is vertically arranged with the limiting frame 6, and the two transverse locking frames 9 are fixedly connected with an end face locking seat 16, and the opposite side of the end face locking seat 16 is provided with a non-slip rubber pad, and the end face of the non-slip rubber pad is provided with anti-slip grooves, and the grooves adopt a cross-grid design, and the end face locking seat 16 and the package are increased by increasing the roughness of the contact surface. The friction between the batteries prevents the batteries from being displaced due to vibration during the rolling process, ensuring the packaging accuracy. The center position of the connecting honing plate 5 is rotatably connected to the center rotating frame 10, and the center rotating frame 10 is symmetrical with the center point of the connecting honing plate 5. The two ends of the center rotating frame 10 are connected to the transverse locking frame 9 through a rotating frame 11, and the two rotating frames 11 are symmetrical with the center of the connecting honing plate 5, and the rotating frame 11 is rotatably connected to the center rotating frame 10, and the rotating frame 11 is rotatably connected to the transverse locking frame 9, and the rotating frame 11 is rotatably connected to the center line of the transverse locking frame 9. A pushing cylinder 12 is provided on the connecting honing plate 5, and the piston rod end of the pushing cylinder 12 is rotatably connected to one of the transverse locking frames 9, realizing the synchronous reverse movement of the transverse locking frames 9 on both sides, ensuring the parallelism of the locking seats 16 at both end surfaces, and avoiding the packaging offset of the battery due to the tilt of the clamping.

[0036] During use, the electric slide rail 3 drives the sliding seat 4 to move up and down along the side wall of the truss 2, adjusting the height of the connecting honing plate 5 and the end face locking seat 16 to match the height of the battery to be packaged. To ensure that the end face locking seat 16 can accurately align with the upper and lower end faces of the battery, when the piston rod of the cylinder 12 is retracted, the upper side transverse locking frame 9 is pushed upward; through the linkage of the rotating frame 11 and the central rotating frame 10, the lower side transverse locking frame 9 is synchronously moved downward, so that the end face locking seats 16 are close to the center and clamp the battery. The central rotating frame 10 rotates around the center point of the connecting honing plate 5 as the axis, and the two ends of the rotating frame 11 rotate around the connection point of the central rotating frame 10 and the transverse locking frame 9 respectively, ensuring synchronous reverse movement of the two sides. When the piston rod of the cylinder 12 is extended, the transverse locking frame 9 moves in the opposite direction.

[0037] like Figure 6-Figure 9As shown, a side wall rolling mechanism is installed on the machine base 1 through a drive shaft, and two end face locking seats 16 are respectively located on the upper and lower sides of the side wall rolling mechanism, and the side wall rolling mechanism includes a fixed bracket 13, and the fixed bracket 13 is installed on the drive shaft, and a fixed drum frame 14 is fixedly connected to the fixed bracket 13, and the center line of the drive shaft does not coincide with the center line of the fixed drum frame 14, and the fixed drum frame 14 is externally rotatably connected with a rotating ring 15, and the end face of the rotating ring 15 is provided with a plurality of fixed supports 17, and the fixed supports 17 are circumferentially arranged around the center line of the rotating ring 15, and the end face of the fixed drum frame 14 is provided with a plurality of sleeves 18, and the sleeves 18 are circumferentially arranged around the center line of the fixed drum frame 14, each of the fixed supports 17 is provided with a rolling roller 19 through a bearing, and each rolling roller 19 is inserted into the sleeve 18 corresponding in position and slidably connected to the sleeve 18.

[0038] Specifically, the fixed cylinder frame 14 includes a middle section fixed ring 1401, and the fixed bracket 13 is fixedly connected to the side wall of the middle section fixed ring 1401, the end face of the middle section fixed ring 1401 is fixedly connected with the end face ring 1402, and the rotating ring 15 is rotatably connected to the outer wall of the end face ring 1402, and the inner side wall of the rotating ring 15 is fixedly connected with a locking ring 20, and a locking ring groove 21 is provided on the side wall of the end face ring 1402, and the locking ring 20 is located in the locking ring groove 21, the locking ring 20 on the inner side of the rotating ring 15 is a circular boss, and the locking ring groove 21 of the end face ring 1402 is a corresponding groove. The axial displacement of the rotating ring 15 is limited by the boss-groove cooperation, while allowing its circumferential rotation, ensuring that the rolling roller 19 maintains a stable radial trajectory during eccentric motion and reduces mechanical wear.

[0039] A push column 22 is rotatably connected to the side wall of the rotating ring 15, a central shaft 23 is provided on the fixed bracket 13, and the center line of the central shaft 23 coincides with the center line of the fixed cylinder frame 14, a driving frame 24 is installed on the central shaft 23 and the push column 22, the central shaft 23 is driven by a driving motor 1 25, and the driving motor 1 25 is fixedly connected to the fixed bracket 13, a driving motor 2 26 is installed in the machine base 1, and the output shaft of the driving motor 2 26 is connected to the driving shaft through a coupling.

[0040] During use, drive motor 26 rotates the drive shaft, driving fixed bracket 13 and fixed cartridge frame 14 to rotate about the centerline of the drive shaft (the centerline of the fixed cartridge frame does not coincide with the centerline of the drive shaft). Drive motor 1 25 drives push column 22 through central shaft 23 and drive frame 24, driving rotating ring 15 to rotate about the centerline of fixed cartridge frame 14. Rolling roller 19 is inserted into and slides along sleeve 18 of fixed cartridge frame 14, applying periodic pressure to the battery sidewalls, causing plastic deformation at the edges of the battery casing to achieve a sealed package. The circumferential distribution of sleeve 18 cooperates with the eccentric structure to guide rolling roller 19 along a preset trajectory, ensuring that all points on the battery sidewalls are evenly rolled.

[0041] Working principle:

[0042] First, the driving motor 26 is used to drive the driving shaft to rotate, so that the side wall rolling mechanism is located outside the clamping motion mechanism, and then the battery is prevented from being placed between multiple rolling rollers 19. Then, the driving motor 1 25 is used to drive the push column 22 to rotate through the central shaft 23 and the driving home 24, and the rotating ring 25 is pushed to rotate around the center line of the fixed drum frame 14. The rolling roller 19 is inserted into the sleeve 18 of the fixed drum frame 14 and slides along it. Multiple rolling rollers 19 can simultaneously apply pressure to the side wall of the battery and clamp it. Then, the driving motor 26 is used to drive the driving shaft to rotate, and the side wall rolling mechanism drives the battery to between the two end face locking seats 16 of the clamping motion mechanism, and the electric slide rail 3 drives the sliding seat 4 along The side walls of the truss 2 move up and down, adjusting the height of the connecting honing plate 5 and the end face locking seat 16 so that they are against the upper end face of the battery to be packaged, ensuring that the end face locking seat 16 can accurately align with the upper and lower end faces of the battery. When the piston rod of the cylinder 12 is retracted, the upper end transverse locking frame 9 is pushed upward; through the linkage of the rotating frame 11 and the central rotating frame 10, the lower end transverse locking frame 9 moves downward synchronously, causing the upper and lower end face locking seats 16 to move toward the center and clamp the battery. At this time, the battery clamping is transferred from the side wall rolling mechanism to the clamping motion mechanism, and then the electric slide 3 drives the clamping motion mechanism to move the battery in the vertical direction. The battery side wall contacts the rolling roller 19 to generate friction. The rolling roller 19 rotates under the action of friction. At the same time, due to the eccentric structure of the fixed cylinder frame 14 and the drive shaft, it applies periodic rolling pressure to the battery side wall during the revolution, causing the edge of the shell to plastically deform and achieve sealing.

[0043] After the packaging is completed, the cylinder 12 is retracted and the end face locking seat 16 releases the battery. The side wall rolling mechanism moves the battery to the unloading position, completing a working cycle.

[0044] Example 2

[0045] Based on the first embodiment, the difference is that Figure 10-12As shown, the number of side wall rolling mechanisms is not less than two, different side wall rolling mechanisms correspond to different workstations, and the angle of the gear tooth distribution on the incomplete gear 27 corresponds to the number of side wall rolling mechanisms (for example, 3 mechanisms correspond to a 120° gear tooth distribution), that is, after the driving motor 26 drives the transmission gear 28 to rotate through the incomplete gear 27, the side wall rolling mechanism can be rotated to the corresponding workstation, and the truss 2 is set on the machine base 1 through the electric slide rod.

[0046] The central shaft 23 is driven by a drive motor 25, and the drive motor 25 is fixedly connected to the fixed bracket 13. A drive motor 26 is installed in the machine base 1. The output shaft of the drive motor 26 and the drive shaft are connected through an intermittent transmission component, and the intermittent transmission component is located in the machine base 1. The intermittent transmission component includes an incomplete gear 27, and the incomplete gear 27 is installed on the output shaft of the drive motor 26. A transmission gear 28 is installed on the drive shaft, and the transmission gear 28 is engaged with the incomplete gear 27.

[0047] The equipment is equipped with multiple side wall rolling mechanisms (number ≥ 2), each corresponding to a different workstation. The drive motor 26 engages with the transmission gear 28 through the incomplete gear 27, and the drive shaft rotates intermittently. The first side wall rolling mechanism drives the rolling roller 19 to clamp the battery through the drive motor 1 25. The drive motor 26 drives the incomplete gear 27 to rotate, causing the transmission gear 28 to rotate to the next workstation. It is worth noting that during the rotation of the side wall rolling mechanism, the truss 2 is driven by the electric slide rod to move, driving the clamping motion mechanism away from the side wall rolling mechanism to avoid motion interference.
