Description

Technical Field

[0001] This invention relates to the field of battery cell processing technology, and in particular to a manual one-time air extraction and sealing tool. Background Technology

[0002] When mass-producing new energy batteries, fully automated production lines are often used, while for testing or small-batch trial production, manual or semi-automatic production lines are usually used to reduce energy consumption. The vacuum sealing process after electrolyte injection is an important step in cell production and can also be done manually or automatically.

[0003] The current manual single-stage vacuum sealing fixture structure mainly consists of three parts: a vacuum chamber, a fixed side of the fixture, and a moving side of the fixture. The vacuum chamber is suspended from the top of the fixed side of the fixture by a plug screw. A spring is installed on the plug screw. In the non-working state, the spring will spring open the vacuum chamber longitudinally, allowing it to be manually pushed and pulled to move laterally. During operation, the battery cell must be placed vertically into the vacuum chamber. To prevent the battery cell from tipping over, clamping strips are installed inside the vacuum chamber, and the battery cell must pass through the clamping strips to be placed vertically. After the battery cell is placed, the vacuum chamber is pushed into the fixture. Then, the moving side of the fixture moves the vacuum chamber towards the fixed side of the fixture to press and seal it, and finally, the vacuum sealing operation is performed.

[0004] In existing technologies, battery cells need to be fixed using clamps to restrict their position, which is time-consuming, labor-intensive, and inefficient. Furthermore, the vacuum chamber uses springs for flexible connection and hoisting, which makes it prone to swaying and unnecessary collisions during pushing and pulling. Summary of the Invention

[0005] In view of this, it is necessary to provide a manual one-time vacuum sealing fixture to solve the problems of cumbersome cell fixing and difficult vacuum chamber installation in existing systems.

[0006] This invention provides a manual single-stage vacuum sealing fixture, comprising:

[0007] A base, on which a linear track is provided;

[0008] A pull-out assembly includes a sealing frame, support members, and a snap-fit ​​unit for installing battery cells. The sealing frame is slidably connected to the linear track. The two support members are inclined and fixedly connected to the inner walls of both sides of the sealing frame. The two ends of the snap-fit ​​unit are movably snapped into the support members.

[0009] A sealing assembly is disposed on both sides of the linear track, and the sealing assembly abuts against the sealing frame from both sides to form a sealing cavity for accommodating the battery cell;

[0010] An encapsulation assembly is connected to the sealing assembly, the encapsulation assembly including a movable heat sealer located in the sealing cavity, the heat sealer being capable of sealing the battery cell.

[0011] Furthermore, the support member is provided with multiple snap-fit ​​slots, which are equidistantly arranged along the length direction of the support member, and the two ends of the snap-fit ​​unit snap-fit ​​with the snap-fit ​​slots.

[0012] Furthermore, the snap-fit ​​unit includes a lower snap-fit ​​bracket and an upper load-bearing bar, with both ends of the snap-fit ​​bracket and the load-bearing bar snapping into different snap-fit ​​slots to adjust the height and span of the snap-fit ​​bracket and the load-bearing bar.

[0013] Furthermore, the bottom of the sealing frame is provided with a second slider that is slidably connected to the linear track, and the second slider is fixedly connected to the sealing frame.

[0014] Furthermore, the sealing assembly includes two abutment housings that can move relative to each other along a linear track. The two abutment housings abut against the sealing frame to form a sealing cavity. The abutment housings are provided with sealing rings that abut against the sealing frame.

[0015] Furthermore, the base is provided with drive units on both sides. The drive unit includes a bracket fixedly connected to the base and a second drive member. The two ends of the second drive member are respectively connected to the bracket and the abutment housing.

[0016] Furthermore, the base is also provided with a guide rail that is perpendicular to the linear track, and the bottom of the abutment housing is slidably connected to the guide rail.

[0017] Furthermore, the abutting housing includes a sealing plate for abutting against the sealing frame and a heat-sealing cavity integrally formed with the sealing plate. The inner cavity of the heat-sealing cavity communicates with the sealing cavity, and the heat-sealing head is disposed in the heat-sealing cavity.

[0018] Furthermore, the heat-sealed cavity is equipped with an openable and closable valve and a vent, and the valve is connected to a vacuum pump.

[0019] Furthermore, the packaging assembly also includes a first driving member, the output end of which is connected to the heat sealing head to drive the heat sealing head to move relative to the battery cell.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] This invention discloses a manual single-stage vacuum sealing fixture. A pull-out assembly is mounted on a base. The pull-out assembly includes a sealing frame, supporting members, and snap-fit ​​units for mounting battery cells. The sealing frame is slidably connected to a linear track, allowing it to move relative to the track. The movement is confined to the linear track, resulting in more stable relative movement and preventing unnecessary collisions. Two supporting members are inclined and fixedly connected to the inner walls of the sealing frame on both sides. The two ends of the snap-fit ​​units are movably snapped into the supporting members, allowing adjustment of the position and span of the snap-fit ​​units to adapt to the battery cells.

Detailed Implementation

[0033] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0034] This embodiment presents a manual single-stage vacuum sealing fixture, relating to the field of battery cell processing technology. It modifies the lifting and installation of the vacuum chamber to a stable sliding insertion method, preventing collisions within the vacuum chamber. This modification to the battery cell installation method facilitates battery cell installation.

[0035] Please see Figures 1 to 6 The manual one-time air extraction sealing tool in this embodiment includes: a base 1, a pull-out component 4, a sealing component 2, and a sealing component 3.

[0036] The base 1 is provided with a linear track 106, and the components that cooperate with the linear track 106 can slide freely along the linear track.

[0037] The pull-out assembly 4 includes a sealing frame 413, support members 405, and snap-fit ​​units for mounting battery cells. The sealing frame 413 is specifically a square frame that is slidably connected to a linear track 106. The sealing frame 413 can move relative to the linear track 106, and its movement trajectory is confined to the linear track 106, resulting in more stable relative movement and preventing unnecessary collisions. The two support members 405 are inclined and fixedly connected to the inner walls of both sides of the sealing frame 413. The two ends of the snap-fit ​​unit are movably snapped into the support members 405, allowing adjustment of the position and span of the snap-fit ​​unit as needed to adapt to the battery cell. The battery cell can be quickly connected and fixed to the snap-fit ​​unit, shortening the installation time and improving the battery cell packaging efficiency.

[0038] The sealing assembly 2 is disposed on both sides of the linear track 106. The sealing assembly 2 abuts against the pull-out assembly 4 from both sides to form a sealed cavity for accommodating the battery cell. By evacuating the sealed cavity into a vacuum, it is convenient to vacuum seal the battery cell.

[0039] The encapsulation component 3 is connected to the sealing component 2. The encapsulation component 3 includes a movable heat sealing head 301, which is located in the sealing cavity and can seal the battery cell.

[0040] During use, the snap-fit ​​unit is quickly snapped onto the two support members 405, and the battery cell is then installed and fixed onto the snap-fit ​​unit. The sealing frame 413 is pushed into the sealing assembly 2 along the straight track 106. The sealing assembly 2 and the sealing frame 413 abut against each other to form a sealing cavity. After the sealing cavity is evacuated, the battery cell is sealed from both sides using the heat sealing head 301.

[0041] Please see Figure 2 The base 1 includes a large base plate 101 and a small base plate 102 arranged horizontally, parallel to each other and connected to each other. Foot cups 109 are fixedly connected to the four bottom corners of the large base plate 101 and the two bottom ends of the small base plate 102, isolating the ground from the two base plates. Brackets 103 and guide rails 105 are symmetrically installed on both sides of the large base plate 101. The guide rails 105 are perpendicular to the linear track 106. A small limiting block 108 is provided at one end of the guide rail 105 near the inner side of the large base plate 101, limiting the extreme position of the guide rail 105 to prevent objects from derailing. The linear track 106 spans the middle of the large base plate 101 and the small base plate 102. Large limiting blocks 107 are provided at both ends of the linear track 106, limiting the extreme position of the linear track 106 to prevent objects from derailing.

[0042] Please see Figure 3 and Figure 4The sealing assembly 2 includes two abutment housings 213 that can move relative to the linear track 106. A first slider 209 is provided between the abutment housing 213 and the guide rail 105, allowing the abutment housing 213 to slide relative to the guide rail 105 with the aid of the first slider 209. The abutment housing 213 includes a sealing plate 201, a sealing cavity seat plate 202, a sealing cavity top plate 203, a sealing cavity side plate 204, a sealing cavity bottom plate 205, and a sealing cavity rear cover plate 206. The sealing cavity seat plate 202 is fixedly connected to the first slider 209. The two sealing cavity side plates 204 are fixed to both sides of the sealing cavity seat plate 202. The sealing cavity top plate 203 is fixedly connected to the two sealing cavity side plates 204 respectively, forming a square frame. The sealing cavity rear cover plate 206 is located on the side of the square frame away from the linear track, and is fixedly connected to the two sealing cavity side plates 204 and the sealing cavity top plate 203 respectively. A sealing plate 201 is disposed on the side of the square frame near the linear track. The sealing plate 201 is fixedly connected to the two sealing cavity side plates 204, the sealing cavity seat plate 202, and the sealing cavity top plate 203. The two sides of the sealing cavity bottom plate 205 are fixedly connected to the two sealing cavity side plates 204. The third side of the sealing cavity bottom plate 205 is perpendicular to the sealing plate 201 and fixedly connected to the sealing plate 201. The fourth side of the sealing cavity bottom plate 205 is fixedly connected to the bottom of the sealing cavity rear cover plate 206, forming a heat-sealing cavity 214 for accommodating the heat-sealing head 301. A rectangular opening is provided on the side of the sealing plate 201 opposite to the linear track 106. The rectangular opening connects the inner cavity of the sealing frame 413 and the inner cavity of the heat-sealing cavity 214. Compared with the cavity formed by the entire abutment shell 213 and the sealing frame 413, the volume is reduced, the time required for vacuuming is reduced, and the energy consumption is less. Meanwhile, the heat-sealing cavity 214 can better cooperate with the heat-sealing head 301, which can limit the movement trajectory of the heat-sealing head 301 and ensure that the heat-sealing head 301 accurately acts on the battery cell.

[0043] A crossbeam 207 is provided at the middle position of the rear of the sealing cavity side plate 204. A second driving member 104 is provided between the crossbeam 207 and the bracket 103. The two ends of the second driving member 104 are connected to the bracket and the crossbeam 207 respectively. The second driving member 104 can drive the abutment housing 213 to move along the guide rail 105.

[0044] It should be noted that: a pressure plate 211 is provided at the upper end of the outer side of the sealing cavity side plate 204, and a sealing ring 212 is provided around the periphery of the sealing plate 201. The sealing ring 212 is set along the edge of the sealing plate 201, and the rectangular opening is surrounded by the sealing ring 212 in the middle. The sealing ring 212 can enhance the sealing performance between the sealing plate 201 and the sealing frame. A clearance groove is machined at the rear end of the sealing cavity seat plate 202 to avoid interference with the bracket 103 on the base 1. A cable routing hole is opened at the upper end of the sealing cavity side plate 204. The cable routing hole is sealed by the pressure plate 211 pressing the silicone skin. A groove is opened in the middle of the sealing cavity side plate 204 for installing the crossbeam 207.

[0045] A valve body 210 is provided on the outside of the sealing cavity side plate 204. The valve body 210 is specifically a two-way solenoid valve. One end of the valve body 210 is connected to the sealing cavity, and the other end is connected to a vacuum pump for controlling the extraction of gas from the sealing cavity. A vent nozzle 208 is installed near the valve body 210. The vent nozzle 208 is specifically an L-shaped vent connector. The vent nozzle 208 passes through the sealing cavity side plate 204 and is fixedly connected to the sealing cavity side plate 204. The vent nozzle 208 connects the sealing cavity to the outside world, allowing outside air to be introduced into the vacuum-state sealing cavity to break the vacuum state of the sealing cavity.

[0046] Please see Figure 5 The encapsulation assembly 3 also includes a drive base plate 305 fixed to the rear cover plate 206 of the sealing cavity, a first drive member 306 and a guide sleeve 307 fixed to both ends of the drive base plate 305, adjusting blocks 311 fixed to the four corners of the rear cover plate 206 of the sealing cavity, adjusting screws 312 mounted on the adjusting blocks 311 for fine-tuning the vertical position of the drive base plate 305, a connecting beam 310 fixed to the first drive member 306, and a connecting beam 310 fixed between the first drive member 306 and the drive base plate 305. The cylinder heat insulation plate 313 is fixed from the inside out to the connecting beam 310, along with the limiting screw 309 and guide post 308 used to adjust the stroke of the first driving component 306. A head base 304 is fixed to the other end of the guide post 308, which passes through the guide sleeve 307, the driving base plate 305, and the sealing cavity rear cover plate 206. A head heating seat 302, separated by the head heat insulation plate 303, is fixed to the head base 304. A heat-sealed head 301 is fixed to the head heating seat 302. The heat-sealed head 301, head heating seat 302, head heat insulation plate 303, and head base 304 are located inside the pull-out assembly 4. To avoid deformation due to excessive length and affecting accuracy, the heat-sealed head 301, head heat insulation plate 303, and head heating seat 302 are divided into two parts, each corresponding to one battery cell. A circular through hole is opened along the length of the head heating seat 302 for installing a heating rod for heating.

[0047] It should be noted that the stroke of the first driving component 306 is greater than that of the second driving component 104, and the heat sealing head 301 uses an inclined surface parallel to the battery cell for sealing. In the non-working state, the heat sealing head 301 does not protrude from the sealing plate 201, ensuring that the pull-out assembly 4 will not collide with the heat sealing head 301 when it moves laterally.

[0048] Please see Figure 6The pull-out assembly 4 includes a second slider 412 connected to the linear track 106, a slider pad 411 fixed to the second slider 412, a vacuum chamber bottom plate 402 fixed to the slider pad 411, a vacuum chamber left side plate 403 and a vacuum chamber right side plate 404 vertically fixed to both sides of the vacuum chamber bottom plate 402, and a vacuum chamber top plate 401. The vacuum chamber top plate 401 is located directly above the vacuum chamber bottom plate 402 and is fixedly connected to the vacuum chamber left side plate 403 and the vacuum chamber right side plate 404 respectively.

[0049] The two ends of the support member 405 are fixedly connected to the bottom plate 402 and the top plate 401 of the vacuum chamber, respectively. The support member 405 has multiple snap-fit ​​slots, which are equidistantly arranged along the length of the support member 405. The snap-fit ​​unit includes a slot bracket 406 located below and a load-bearing strip 408 located above. The two ends of the slot bracket 406 snap into the snap-fit ​​slots, and the two ends of the load-bearing strip 408 also snap into the snap-fit ​​slots. The two ends of the slot bracket 406 and the load-bearing strip 408 snap into different slots to adjust the height and span of the slot bracket and the load-bearing strip. The slot bracket 406 has a cell slot 407 for carrying the battery cells. Two cell spacers 409 are provided on the load-bearing strip 408 and the cell slot 407, which can separate the two battery cells. The handle 410 on the right side plate 404 of the vacuum chamber allows workers to manually pull the sealing frame.

[0050] In specific implementations, the snap-fit ​​unit can have other implementation methods. The snap-fit ​​unit may include a slot with an open side and a hollow interior. The battery cell is inserted into the slot, and both ends of the slot are snapped into the snap-fit ​​groove. The snap-fit ​​unit may include a connector plate and a battery cell clamp. The battery cell clamp is fixed to the connector plate and can fix the battery cell to the connector plate. Both ends of the connector plate are snapped into the snap-fit ​​groove.

[0051] Workflow: First, grip handle 410 and pull out the pull-out assembly 4. Then, install the slot bracket 406 and the load-bearing bar 408 into the appropriate positions on the support 405, and place the two battery cells on the battery cell slot 407 and the load-bearing bar 408. Push in the pull-out assembly 4, and the abutment housing 213 is pressed against the pull-out assembly 4 under the action of the second drive member 104. At this time, the sealing ring 212 is pressed between the abutment housing 213 and the sealing frame 413. Open the valve body 210 to start evacuating air. After the vacuum degree reaches the required level, the valve body 210 closes. The heat sealing head in the encapsulation assembly 3 moves towards the battery cell under the action of the first drive member 306 to start sealing. After sealing is completed, the encapsulation assembly 3 returns to its original position under the action of the first drive member 306, and the vent 208 vents to break the vacuum. Then, the pull-out assembly 4 returns to its original position under the action of the second drive member 104, and the processed battery cell is removed from the slot bracket 406.

[0052] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of the present invention.
