Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a cell processing device and a battery production system. Background Technology

[0002] In the production of pouch batteries, the voltage testing of the cells and the bending of the tabs are crucial steps to ensure battery performance and safety. Voltage testing, as the primary step in guaranteeing battery safety and functionality, screens out substandard cells by accurately measuring open-circuit voltage and internal resistance, thus avoiding potential safety risks. The tab bending process directly affects the battery's conductivity and mechanical stability; its accuracy and consistency are critical to the battery's long-term reliability. These two processes play an irreplaceable role in improving battery quality and enhancing market competitiveness.

[0003] Currently, the voltage testing and tab bending processes for existing battery cells need to be performed in separate workstations. After completing one process, the battery cell needs to be transferred to the next process location before it can be processed, which increases the time and cost of material handling and results in a slower production cycle. Therefore, this separate process has production efficiency issues. Utility Model Content

[0004] In view of this, the present invention provides a cell processing device and a battery production system to solve the problem of low production efficiency in the existing cell processing process.

[0006] Beneficial effects: By setting up a test unit and a bending unit for the same processing base, after the battery cell is placed on the processing base, the test drive unit drives the test component to press onto the tab. After the test end contacts the tab, the voltage and internal resistance of the battery cell can be tested. After the test is completed, the bending drive unit drives the bending component to move. The bending structure of the bending component can bend the tab to a preset angle.

The adjustment seat has multiple connection positions arranged along a first direction on its side wall, and the test component is detachably connected to at least one connection position.

[0008] Beneficial effects: The test assembly is indirectly connected to the test drive unit through the adjustment base.

[0011] In one alternative embodiment, a second direction intersecting the first direction is also provided; along the second direction, the end face of the test end away from the cell body is a limiting surface, which is used to limit the degree of bending of the tab.

[0012] Beneficial effects: This type of test terminal, while performing the testing function and fixing the tab, can also limit the bending of the tab. When the bending unit bends the tab to contact the limiting surface, the tab can no longer bend, thus avoiding excessive bending of the tab.

[0013] In one optional embodiment, the test drive is a drive cylinder, which has a drive end that extends and retracts in a first direction. An adjusting seat is connected to the drive end. The side wall of the test drive is provided with a guide structure that extends in the first direction. The adjusting seat has a mating structure for guiding and engaging with the guide structure.

[0019] In one optional embodiment, a limiting block is provided on the outer wall of the support plate, the limiting block is located near the first guide hole, and the limiting block is used to limit the movement range of the first guide rod in the first guide hole.

[0020] Beneficial effect: By setting a limit block, the swing range of the bending component can be adjusted more flexibly without changing the guide hole.

[0021] In one optional embodiment, the support plate is provided with a second guide hole, which is spaced apart from the first guide hole, and the bending assembly has a second guide rod, which is movably inserted through the second guide hole.

[0022] Beneficial effects: Setting a second guide hole and a second guide rod can further improve the stability of the bending component during movement.

[0041] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] The following is combined Figures 1 to 5 The following describes embodiments of the present invention.

[0043] In related technologies, since the voltage testing of the battery cell and the bending of the tabs need to be carried out in separate workstations, this processing method may also introduce additional operational risks, such as damage or contamination of the battery cell during the transfer between different workstations.

[0044] According to an embodiment of the present invention, in one aspect, a battery cell processing apparatus is provided, having a first direction X, the battery cell processing apparatus comprising: a processing base 1, a testing unit 2, and a bending unit 3;

[0045] The processing base 1 is used to place the battery cell 4; the testing unit 2 is disposed on one side of the processing base 1, and the testing unit 2 includes a testing component 201 and a testing drive 202. Along the first direction X, the testing component 201 is located on one side of the tab 401 of the battery cell 4, and the end of the testing component 201 near the tab 401 forms a testing end 2011. The testing drive 202 is used to drive the testing component 201 to move along the first direction X; the bending unit 3 is disposed on one side of the processing base 1, and the bending unit 3 includes a bending component 301 and a bending drive 302. The bending component 301 has a bending structure 3011 for bending the battery cell 4, and the bending drive 302 is used to move the bending component 301 along a preset trajectory.

[0046] The battery cell processing apparatus of this embodiment has a test unit 2 and a bending unit 3 respectively set for the same processing base 1. After the battery cell 4 is placed on the processing base 1, the test drive 202 drives the test component 201 to press onto the tab 401. After the test end 2011 contacts the tab 401, it can test the voltage and internal resistance of the battery cell 4. After the test is completed, the bending drive 302 drives the bending component 301 to move. The bending structure 3011 of the bending component 301 can bend the tab 401 to a preset angle. The processing apparatus of this embodiment integrates the two key process steps of voltage testing and tab bending into the same device. This not only reduces the processing steps in the battery cell production process and improves the processing cycle, but also reduces production costs and potential quality risks, effectively solving the problem of low production efficiency in the existing battery cell processing process.

[0047] It should be noted that, in this embodiment, the first direction X refers to Figure 1 The middle arrow points to the direction of "X", and the second direction, Y, refers to... Figure 1 The direction indicated by the middle arrow "Y" is the third direction Z. Figure 1 The direction of "Z" indicated by the middle arrow.

[0048] Specifically, since the test end 2011 can fix the position of the tab 401 after pressing it, there is no need to set an additional pressing structure in the bending unit 3. During the cell 4 processing, the test unit 2 and the bending unit 3 can work together, thus simplifying the structure of the bending unit 3.

[0049] Furthermore, the test end 2011 is equipped with conductive components.

[0050] like Figure 3 As shown, the processing base 1 is provided with a processing position 101 for placing the battery cell 4.

[0051] In one possible implementation, such as Figure 1 and Figure 2As shown, the test unit 2 also includes an adjustment seat 203, which is connected to the drive end 2021 of the test drive component 202. Multiple connection positions are arranged on the side wall of the adjustment seat 203 along the first direction X. The test component 201 is detachably connected to at least one connection position. The test component 201 is indirectly connected to the test drive component 202 through the adjustment seat 203. Since the test component 201 and the adjustment seat 203 are detachably connected, the position of the test component 201 on the adjustment seat 203 can be conveniently adjusted according to the specifications and dimensions of different battery cells 4, thereby meeting the voltage test requirements of different battery cells 4.

[0052] Specifically, there is no limitation on the number of connection positions, which can be two, three, or more than four. Multiple connection positions can be set at intervals or continuously. There is no limitation on the detachable connection method between the test component 201 and the adjustment seat 203. The detachable connection can be achieved by fastening components, locking claws, or connecting keys through its own connection slots.

[0053] It is understood that, as an alternative implementation, the adjustment seat 203 may not be provided, and the test component 201 may be directly connected to the drive end 2021 of the test driver 202. This type of test component 201 installation can also complete the test function.

[0054] In one possible implementation, such as Figure 1 and Figure 2 As shown, the test assembly 201 includes a buffer seat 2012, a test structure 2013, and an elastic element 2014. The test structure 2013 has a test end 2011. The buffer seat 2012 is connected to the drive end 2021 of the test drive unit 202. The test structure 2013 is movably disposed on the buffer seat 2012 along the first direction X. The side of the test structure 2013 away from the cell 4 cooperates with the buffer seat 2012 through the elastic element 2014. This test assembly 201 with buffering capability can not only avoid rigid collision between the test end 2011 and the tab 401, but also the elastic element 2014 can stably provide pressure, so that the test structure 2013 and the tab 401 are in continuous and stable contact. In addition, when the test assembly 201 shakes or vibrates, the elastic element 2014 can also effectively reduce the vibration transmitted to the test structure 2013.

[0055] Specifically, such as Figure 2 As shown, the test structure 2013 is slidably mounted on the buffer seat 2012. The side wall of the buffer seat 2012 is provided with a guide rail 2015. The test structure 2013 is provided with a corresponding slider 2016 that slides in cooperation with the guide rail 2015. This cooperation can ensure that the test structure 2013 moves stably along a preset trajectory.

[0056] In addition, such as Figure 2 As shown, along the first direction X, a limiting plate 2017 is also fixedly provided at the bottom of the buffer seat 2012. The limiting plate 2017 is used to block the slider 2016 and prevent the slider 2016 from falling off the guide rail 2015.

[0057] Furthermore, such as Figure 2 As shown, the buffer seat 2012 is L-shaped and includes a first seat section extending along the first direction X and a second seat section extending along the second direction Y. The guide rail 2015 is disposed on the first seat section. The second seat section is fixedly connected to the first seat section and is disposed opposite to the test structure 2013. The elastic member 2014 is disposed between the second seat section and the test structure 2013. The test structure 2013 has a mounting groove on its wall near the second seat section. At least a portion of the elastic member 2014 is inserted into the mounting groove to prevent the elastic member 2014 from moving arbitrarily.

[0058] In one possible implementation, such as Figure 1 and Figure 2 As shown, it also has a second direction Y intersecting the first direction X; along the second direction Y, the end face of the test end 2011 away from the body of the cell 4 is a limiting surface 20111. The limiting surface 20111 is used to limit the bending degree of the tab 401. This type of test end 2011, while completing the testing function and fixing the tab 401, can also limit the bending of the tab 401. When the bending unit 3 bends the tab 401 to contact the limiting surface 20111, the tab 401 can no longer bend, thus avoiding the tab 401 from being over-bent.

[0059] Specifically, such as Figure 2 As shown, since there are usually multiple tabs 401 and they are spaced apart, the test end 2011 also has multiple spaced test ends. The side of each test end closest to the tab 401 is a detection surface, and the test end away from the cell 4 body has a limiting surface 20111.

[0060] In one possible implementation, such as Figure 2 As shown, the test drive component 202 is a drive cylinder, which has a drive end 2021 that extends and retracts along the first direction X. The adjusting seat 203 is connected to the drive end 2021. The side wall of the test drive component 202 is provided with a guide structure 2022 that extends along the first direction X. The adjusting seat 203 has a mating structure 2031 for guiding and engaging with the guide structure 2022. The adjusting seat 203 and the test drive component 202 are connected in this way, which makes the movement of the adjusting seat 203 more stable and reliable, and reduces the shaking and vibration of the adjusting seat 203 during the movement.

[0061] In one possible implementation, the test unit 2 further includes a mounting plate 204 and a connecting plate 205. The test drive component 202 is connected to the mounting plate 204 through the connecting plate 205. The mounting plate 204 serves to support the test component 201 and the test drive component 202, and the connecting plate 205 serves to connect them. The specific specifications and dimensions of the mounting plate 204 and the connecting plate 205 are not limited and can be flexibly selected according to the actual installation situation.

[0062] In one possible implementation, such as Figure 3 and Figure 4 As shown, the processing base 1 has an arrangement space along the first direction X. The arrangement space is located on the side of the cell 4 away from the test end 2011. The bending component 301 is located in the arrangement space. The bending component 301 is swayably set on the processing base 1. The test drive component 202 is swayably set on the processing base 1 and is hinged to the bending component 301. This arrangement of the bending unit 3 can make the cell processing device more compact as a whole and can make more effective use of the space inside the processing base 1. In addition, the bending component 301 moves on the processing base 1, which can avoid the bending error that is easy to occur when the bending unit 3 is an independent component.

[0063] Specifically, there is no limitation on the specific form of the processing base 1. The processing base 1 can be a box structure or a frame structure, and can be flexibly selected.

[0064] Furthermore, there is no limitation on the movement of the bending component 301 on the machining base 1. It can move along a groove or hole on the machining base 1, or it can move on the machining base 1 via a guide rail.

[0065] Furthermore, since the bending component 301 bends the tab 401 by swinging itself, this type of bending component 301 requires less space to move compared to a straight line, and the bending process of the tab 401 is also more gentle, which can reduce the wear on the surface of the tab 401.

[0066] In one possible implementation, such as Figure 3 and Figure 4 As shown, it also has a third direction Z intersecting the first direction X; the processing base 1 includes a top plate 102 and a support plate 103. The support plate 103 is located on the side of the top plate 102 away from the test end 2011. The support plate 103 extends along the third direction Z and is fixedly connected to the top plate 102. The support plate 103 is provided with a first guide hole 1031. The bending component 301 has a first guide rod 3012. The first guide rod 3012 is movably inserted into the first guide hole 1031. The overall structure of the processing base 1 is simple and reliable. Through the cooperation of the first guide rod 3012 and the first guide hole 1031, the movement process of the bending component 301 can be effectively guided and constrained.

[0067] Since the bending component 301 is a swinging component, the first guide hole 1031 extends in an arc shape. The cross-sectional shape of the first guide rod 3012 is not limited and can be a cylinder, prism, etc., as long as it can move along the first guide hole 1031.

[0068] It should be noted that since the bending component 301 is constrained by both the first guide hole 1031 and the test drive component 202, even if the first guide rod 3012 is a cylindrical rod, the bending component 301 can move along a predetermined trajectory during the swinging process and will not rotate arbitrarily along the axis of the cylindrical rod.

[0069] Specifically, such as Figure 3 As shown, two support plates 103 are spaced apart along the third direction Z. The two support plates 103 and the top plate 102 together form an arrangement space. A test plate 1021 is detachably mounted on the top plate 102. The test plate 1021 is used to support the tab 401. Since the size and bending degree of the tab 401 need to be adjusted according to the requirements, this detachable test plate 1021 is easier to disassemble and replace. It can be replaced with a test plate 1021 of the corresponding size as needed.

[0070] In addition, the guide hole is easier to process and manufacture. By changing the extension direction of the guide hole, the movement trajectory of the bending component 301 can be changed. At the same time, by controlling the length of the guide hole, the maximum swing amplitude and swing position of the bending component 301 can also be limited.

[0071] In one possible implementation, such as Figure 3 and Figure 4 As shown, a limiting block 1033 is provided on the outer wall of the support plate 103. The limiting block 1033 is located near the first guide hole 1031. The limiting block 1033 is used to limit the movement range of the first guide rod 3012 in the first guide hole 1031. By setting the limiting block 1033, the swing range of the bending component 301 can be adjusted more flexibly without changing the guide hole.

[0072] Specifically, in order for the limiting block 1033 to function as a limiting block, a portion of the structure of the limiting block 1033 can be intercepted at the first guide hole 1031 to limit the first guide rod 3012. Alternatively, the structure of the end of the first guide rod 3012 can be changed so that the end of the first guide rod 3012 has an outwardly extending protrusion, which abuts against the limiting block 1033 to achieve the limiting function.

[0073] In one possible implementation, such as Figure 3 and Figure 4As shown, the support plate 103 is provided with a second guide hole 1032, which is spaced apart from the first guide hole 1031. The bending component 301 has a second guide rod 3013, which is movably inserted into the second guide hole 1032. The second guide hole 1032 and the second guide rod 3013 can further improve the stability of the bending component 301 during movement. In addition, by designing the positions of the first guide hole 1031 and the second guide hole 1032, the bending component 301 can perform additional movement or rotation while swinging, enabling the bending component 301 to achieve a more complex working stroke.

[0074] Specifically, the form of the first guide hole 1031 and the second guide hole 1032 is not limited. They can be concentric and spaced-apart arcs, or they can be spaced-apart curved arc holes with their own independent trajectories.

[0075] In one possible implementation, such as Figure 5 As shown, the bending assembly 301 includes a swing block 3015 and a bending claw 3016. The end of the bending claw 3016 is the bending structure 3011. The first guide rod 3012 and the second guide rod 3013 are rod-shaped structures that pass through the swing block 3015. In order to prevent the first guide rod 3012 and the second guide rod 3013 from coming off during movement, the two ends of the first guide rod 3012 and the second guide rod 3013 are fixedly connected by a mating plate 3014. The bending assembly 301 can achieve a limiting engagement with the limiting block 1033 through the mating plate 3014.

[0076] Among them, the swing block 3015 is hinged to the driving end of the bending drive 302, and the bending drive 302 is a drive cylinder whose driving end can be extended and moved, such as a pneumatic cylinder, electric cylinder, hydraulic cylinder, etc.

[0077] In one possible implementation, the processing base 1 further includes a first mounting base 104 and a second mounting base 105. The first mounting base 104 is connected to the end of the support plate 103 away from the top plate 102 and is used for mounting the bending drive component 302. The second mounting base 105 is connected to the end of the support plate 103 away from the top plate 102 and serves to increase the height of the support plate 103 and the top plate 102.
