Description

Technical Field

[0001] The present application relates to the technical field of battery manufacturing, and in particular to a tab positioning device. Background Art

[0002] The battery packaging machine is a battery packaging equipment that can automatically package lithium-ion batteries or other batteries. It can realize functions such as punching holes in the aluminum film, folding the aluminum film in half and cutting the ends, placing the battery cell package (battery cell into the shell), detecting the tab margins, top sealing, side sealing, side cutting, Hi-pot testing, etc.

[0003] At present, in the existing battery packaging machines, since the connection between the tab and the battery cell is not stable enough, the tab is easily shifted during the process of putting the battery cell into the shell and folding the aluminum film, resulting in poor packaging and a high defective rate, which not only increases production costs, but also wastes resources and reduces production efficiency. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a tab positioning device, which can achieve the technical effect of reducing the defective rate and production cost, and improving production efficiency and production quality.

[0005] An embodiment of the present application provides a tab positioning device, comprising: a tab positioning mechanism, comprising a tab clamp, the tab clamp being used to clamp the tab; and a first driving mechanism connected to the tab positioning mechanism, for driving the tab clamp to open or close.

[0006] In the above implementation process, the tab positioning device can be applied to a battery packaging machine; when the battery packaging machine places the battery cell on the punched aluminum film and prepares to fold it, the first driving mechanism drives the adjustable tab positioning mechanism into place and fixes it to prevent the tab from shifting, thereby achieving a high-quality aluminum film folding effect, reducing the defective rate and production costs, ensuring the packaging quality, and improving production efficiency and production quality.

[0007] Further, the pole lug clamp includes a first pole lug clamp and a second pole lug clamp, the first pole lug clamp includes a first clamping edge and a second clamping edge, the second pole lug clamp includes a third clamping edge and a fourth clamping edge, and the second clamping edge and the third clamping edge are arranged alternately; the pole lug includes a first pole lug and a second pole lug, the first clamping edge and the third clamping edge can fix the first pole lug, and the second clamping edge and the fourth clamping edge can fix the second pole lug; the first driving mechanism is used to drive the first pole lug clamp and the second pole lug clamp to move closer to or away from each other.

[0008] In the above implementation process, the first pole lug clamp and the second pole lug clamp in the pole lug positioning fixture are placed alternately, the first pole lug is clamped by the first clamping edge of the first pole lug clamp and the third clamping edge of the second pole lug clamp, and the second pole lug is clamped by the second clamping edge of the first pole lug clamp and the fourth clamping edge of the second pole lug clamp; therefore, when the first driving mechanism drives the first pole lug clamp and the second pole lug clamp, the clamping of the first pole lug and the second pole lug can be completed at the same time, thereby improving the clamping efficiency and reducing the production cost.

[0009] Furthermore, the pole lug clamp also includes a first connecting member and a second connecting member; the first connecting member respectively connects the first pole lug clamp and the first driving mechanism, and is used to fix the first pole lug clamp to the first driving mechanism; the second connecting member respectively connects the second pole lug clamp and the first driving mechanism, and is used to fix the second pole lug clamp to the first driving mechanism.

[0010] In the above implementation process, the first connecting member is fixedly connected to the first pole lug clamp, the second connecting member is fixedly connected to the second pole lug clamp, and the first connecting member and the second connecting member are respectively connected to the first driving mechanism; thus, when the first driving mechanism drives the first connecting member and the second connecting member, the first pole lug clamp and the second pole lug clamp can be driven to move closer to or away from each other.

[0011] Furthermore, the tab positioning mechanism further includes a limiting member, which is disposed above the tab clamp and is used to limit the height of the tab being tilted.

[0012] In the above implementation process, the limiter is arranged above the pole ear clamp to limit the height of the first pole ear and the second pole ear; when the battery packaging machine is putting the battery cell into the shell and folding the aluminum film, the pole ear of the battery cell may be tilted upward, and the limiter can prevent the pole ear from tilting upward and prevent the pole ear from deviating beyond the allowable value, thereby ensuring the production efficiency and production quality of the battery cell.

[0013] Furthermore, the device also includes a second driving mechanism, which is connected to the tab positioning mechanism and is used to drive the tab positioning mechanism to rise or fall.

[0014] In the above implementation process, on the one hand, the second driving mechanism drives the pole tab positioning mechanism to rise or fall, thereby adjusting the upper and lower positions of the pole tab positioning mechanism to ensure that the pole tab positioning mechanism can correctly position the pole tab of the battery cell; on the other hand, when the second driving mechanism drives the pole tab positioning mechanism to rise or fall, the allowable value of the pole tab tilting of the battery cell can be adjusted to ensure the quality requirements of the production process of different battery cells and improve the practicality and flexibility of the pole tab positioning device.

[0015] Furthermore, the device also includes a tab support block mechanism, which is disposed below the tab clamp and is used to support the tab.

[0016] In the above implementation process, the battery cell is conveyed to the tab positioning device. When the packaging machine performs the processes of shelling the battery cell and folding the aluminum film, the first tab or the second tab on the battery cell may shift downward. At this time, the tab support mechanism can support the first tab or the second tab shifted downward to prevent the first tab or the second tab from tilting downward, thereby ensuring the production efficiency and production quality of the battery cell.

[0017] Furthermore, the device also includes a fixed seat mechanism, the tab support mechanism is arranged on the fixed seat mechanism, and the tab positioning mechanism and the first driving mechanism are arranged on the fixed seat mechanism.

[0018] In the above implementation process, the fixed seat mechanism is fixedly connected to the pole lug support block mechanism 50, and the pole lug support block mechanism can be embedded in the fixed seat mechanism; the fixed seat mechanism can realize the position adjustment of the pole lug support block mechanism, ensuring that the pole lug support block mechanism can still accurately support the pole lug on the battery cell under the production requirements of different process parameters of the battery cell, thereby improving the practicality and flexibility of the pole lug positioning device.

[0019] Furthermore, the device also includes a support seat mechanism, which includes a main frame and a movable guide rail, the movable guide rail is installed on the main frame, and the fixed seat mechanism is installed on the movable guide rail.

[0020] In the above implementation process, the tab positioning mechanism, the first drive mechanism, the second drive mechanism, and the tab support mechanism are all directly or indirectly fixed to the fixed seat mechanism; so that when the fixed seat mechanism moves left and right along the movable guide rail, the tab positioning mechanism and the tab support mechanism can also move accordingly.

[0021] Furthermore, the device also includes a third driving mechanism, which is respectively connected to the supporting seat mechanism and the fixing seat mechanism, and is used to drive the fixing seat mechanism to slide along the movable guide rail.

[0022] In the above implementation process, before the packaging machine performs the battery cell shelling and aluminum film folding processes, the third driving mechanism drives the pole tab positioning mechanism and the pole tab support mechanism to move along the direction of the movable guide rail, thereby adjusting the left and right positions of the pole tab positioning mechanism and the pole tab support mechanism to ensure that the pole tab positioning mechanism can correctly position the pole tab of the battery cell.

[0023] Furthermore, the first driving mechanism is an actuator.

[0024] In the above implementation process, the actuator may be a pneumatic actuator, a hydraulic actuator or an electric actuator.

[0039] The embodiment of the present application provides a tab positioning device, which can be used in a battery packaging machine, such as a battery cell shelling and aluminum film folding station in the battery packaging machine; the tab positioning device includes a tab positioning mechanism and a first driving mechanism. When the battery packaging machine places the battery cell on the aluminum film with punched holes and prepares for folding, the first driving mechanism drives the adjustable tab positioning mechanism to fix the battery cell tab to avoid tab displacement during the battery cell shelling and aluminum film folding process, thereby achieving a high-quality aluminum film folding effect, ensuring packaging quality, and improving production efficiency and production quality.

[0040] Optionally, a tab positioning device provided in an embodiment of the present application may also be applied to other equipment in the field of battery manufacturing, such as welding, packaging and other equipment.

[0041] See also Figure 1 , Figure 1The structure diagram of a tab positioning device provided in an embodiment of the present application is shown in FIG. The tab positioning device comprises a tab positioning mechanism 10 and a first driving mechanism 20 ; wherein the tab of the battery cell 30 is fixed by the tab positioning mechanism 10 .

[0042] Exemplarily, the battery cell 30 includes two tabs, which are two electrodes of the battery cell 30 , namely a first tab 31 and a second tab 32 .

[0043] Exemplarily, the tab positioning mechanism 10 includes a tab clamp, wherein the tab clamp is used to clamp the tab, and the tab clamp includes a first tab clamp 11 and a second tab clamp 12 .

[0044] See also Figure 2a , Figure 2a The first pole tab clamp 11 includes a first clamping edge 111 and a second clamping edge 112 , and a first stopper 113 and a second stopper 114 .

[0045] See also Figure 2b , Figure 2b The second pole tab clamp 12 includes a third clamping edge 121 and a fourth clamping edge 122 , and a third stopper 123 and a fourth stopper 124 .

[0046] Exemplarily, the second clamping edge 112 and the third clamping edge 121 are placed alternately.

[0047] Exemplarily, two tabs of the battery cell 30: the first tab 31 and the second tab 32 are clamped by the first tab clamp 11 and the second tab clamp 12. Specifically, the first clamping edge 111 and the third clamping edge 121 can fix the first tab 31, and the second clamping edge 112 and the fourth clamping edge 122 can fix the second tab 32.

[0048] Exemplarily, the first driving mechanism 20 is used to drive the first pole tab clamp 11 and the second pole tab clamp 12 to move closer to or away from each other.

[0049] In some implementation scenarios, before the packaging machine shells the battery cell 30 and folds the aluminum film, the first driving mechanism 20 drives the first pole lug clamp 11 and the second pole lug clamp 12 to move away from each other, and then after the battery cell 30 is transferred to the folding tooling by the transfer mechanism of the packaging machine, the pole lug positioning device positions the pole lugs of the battery cell 30, wherein the two pole lugs of the battery cell 30: the first pole lug 31 and the second pole lug 32 are located between the first pole lug clamp 11 and the second pole lug clamp 12, specifically, the first pole lug 31 is located between the first clamping edge 111 and the third clamping edge 121, and the second pole lug 32 is located between the second clamping edge 112 and the fourth clamping edge 122; the first driving mechanism 20 drives the first pole lug clamp 11 and the second pole lug clamp 12 to move closer to each other, and the first clamping edge 111 and the third clamping edge 121 move closer to each other, thereby clamping and fixing the first pole lug 31; the second clamping edge 112 and the fourth clamping edge 122 move closer to each other, thereby clamping and fixing the second pole lug 32. After the two tabs of the battery cell 30 are fixed, the folding tooling performs the process of shelling the battery cell 30 and folding the aluminum film, thereby avoiding the displacement of the tabs, achieving a high-quality aluminum film folding effect, ensuring the packaging quality, and improving the production efficiency and production quality.

[0050] Exemplarily, the tab positioning mechanism 10 further includes a limiting member, which is disposed above the tab clamp and is used to limit the height of the tab of the battery cell 30 being tilted.

[0051] In some embodiments, the stopper is installed above the first pole tab clamp 11 and the second pole tab clamp; specifically, the first stopper 113 and the second stopper 114 are installed above the first clamping edge 111 and the second clamping edge 112 of the first pole tab clamp 11, respectively, and the third stopper 123 and the fourth stopper 124 are installed above the third clamping edge 121 and the fourth clamping edge 122 of the second pole tab clamp 12, respectively. In the process of the first pole tab clamp 11 and the second pole tab clamp clamping the first pole tab 31 and the second pole tab 32, the first pole tab 31 and the second pole tab 32 may be tilted upward, thereby causing the pole tabs to deviate, affecting the production efficiency and production quality of the battery cell 30; therefore, the first stopper 113 and the second stopper 114 on the first pole tab clamp 11, and the third stopper 123 and the fourth stopper 124 on the second pole tab clamp 12 can prevent the pole tabs from deviating beyond the allowable value in the process of the first pole tab 31 and the second pole tab 32 being tilted upward, thereby ensuring the production efficiency and production quality of the battery cell.

[0052] Exemplarily, the first driving mechanism 20 is connected to the tab positioning mechanism 10 and is used to drive the tab clamp to open or close.

[0053] In some embodiments, the first driving mechanism 20 is an actuator, which may be a pneumatic actuator, a hydraulic actuator, or an electric actuator.

[0054] In some embodiments, the tab clamp further includes a first connector 13 and a second connector 14; wherein: the first connector 13 is respectively connected to the first tab clamp 11 and the first driving mechanism 20, and is used to fix the first tab clamp 11 to the first driving mechanism 20; the second connector 14 is respectively connected to the second tab clamp 12 and the first driving mechanism 20, and is used to fix the second tab clamp 12 to the first driving mechanism 20. Thus, the tab clamp is fixed to the first driving mechanism 20 through the first connector 13 and the second connector 14, so that the tab clamp is opened or closed under the drive of the first driving mechanism 20; specifically, when the first driving mechanism 20 drives the first connector 13 and the second connector 14 to open or close, the first tab clamp 11 and the second tab clamp 12 can be driven to open or close.

[0055] Exemplarily, the first connecting member 13 is fixedly connected to the first pole tab clamp 11 and the first driving mechanism 20 by screws, respectively; similarly, the second connecting member 14 is fixedly connected to the second pole tab clamp 12 and the first driving mechanism 20 by screws, respectively.

[0056] In some implementation scenarios, the tab positioning device is used in a battery packaging machine, for example, in the process of the battery packaging machine putting the battery cell 30 into the shell and folding the aluminum film. The battery packaging machine is a battery packaging device that can automatically package lithium-ion batteries or other batteries, and can realize functions such as punching holes in the aluminum film, folding and cutting the ends of the aluminum film, placing the battery cell package (battery cell into the shell), detecting the tab margin, top sealing, side sealing, side cutting, Hi-pot testing, etc. It should be understood that the tab positioning device can be used in other processes of the battery packaging machine, and its application in the process of putting the battery cell into the shell and folding the aluminum film is only an example and not a limitation.

[0057] See also Figure 3 , Figure 3 The structure diagram of a tab positioning device provided in an embodiment of the present application. The tab positioning device includes a tab positioning mechanism 10, a first drive mechanism 20, a second drive mechanism 40, a tab support mechanism 50, and a fixing seat mechanism 60.

[0058] It should be understood that the tab positioning mechanism 10 and the first driving mechanism 20 have been described above, and will not be described again here to avoid repetition.

[0059] Exemplarily, the second driving mechanism 40 is connected to the tab positioning mechanism 10 and is used to drive the tab positioning mechanism 10 to rise or fall.

[0060] In some embodiments, the second driving mechanism 40 is an actuator, which may be a pneumatic actuator, a hydraulic actuator, or an electric actuator.

[0061] In some implementation scenarios, the battery cell 30 is conveyed to the tab positioning device by the folding tool in the packaging machine before the battery cell 30 is shelled and the aluminum film is folded. During the conveying process of the battery cell 30, due to the influence of the conveying accuracy or other factors, the tab of the battery cell 30 may not be correctly delivered to the tab positioning mechanism 10. Therefore, the second driving mechanism 40 drives the tab positioning mechanism 10 to rise or fall, thereby adjusting the upper and lower positions of the tab positioning mechanism 10 to ensure that the tab of the battery cell 30 is correctly delivered to the tab positioning mechanism 10.

[0062] In some embodiments, the tab positioning mechanism 10 is connected to the first driving mechanism 20, and the first driving mechanism 20 is fixedly connected to the second driving mechanism 40; when the second driving mechanism 40 drives the first driving mechanism 20 to rise or fall, it can drive the tab positioning mechanism 10 to rise or fall.

[0063] In some embodiments, the tab positioning mechanism 10 is equipped with a limiting member, specifically, a first limiting member 113 and a second limiting member 114 are respectively installed above the first clamping edge 111 and the second clamping edge 112 of the first tab clamp 11, and a third limiting member 123 and a fourth limiting member 124 are respectively installed above the third clamping edge 121 and the fourth clamping edge 122 of the second tab clamp 12. When the second driving mechanism 40 drives the tab positioning mechanism 10 to rise or fall, the allowable value of the tab tilting of the battery cell 30 can be adjusted to ensure the quality requirements of the production process of different battery cells 30, and improve the practicality and flexibility of the tab positioning device.

[0064] Exemplarily, the tab support mechanism 50 is disposed below the tab clamp to support the tab on the battery cell 30 .

[0065] Exemplarily, the tab support mechanism 50 includes two tab supports, see Figure 4 , Figure 4 A structural diagram of a tab support block provided in an embodiment of the present application.

[0066] In some embodiments, the two pole lug support blocks of the pole lug support block mechanism 50 are respectively arranged below the first pole lug clamp 11 and the second pole lug clamp 12, and are nested with the first pole lug clamp 11 and the second pole lug clamp 12; wherein the pole lug support block below the first pole lug clamp 11 is used to support the first pole lug 31 of the battery cell 30, and the pole lug support block below the second pole lug clamp 12 is used to support the second pole lug 32 of the battery cell 30.

[0067] In some implementation scenarios, the battery cell 30 is conveyed to the pole ear positioning device. When the folding tooling in the packaging machine performs the process of shelling the battery cell 30 and folding the aluminum film, the first pole ear 31 or the second pole ear 32 on the battery cell 30 may shift downward. At this time, the pole ear support block mechanism 50 can support the first pole ear 31 or the second pole ear 32 that shifts downward to prevent the first pole ear 31 or the second pole ear 32 from tilting downward, thereby ensuring the production efficiency and production quality of the battery cell 30.

[0068] Exemplarily, the fixing seat mechanism 60 is used to fix other mechanisms of the tab positioning device; for example, the tab support mechanism 50 is disposed on the fixing seat mechanism 60 , and the tab positioning mechanism 10 and the first driving mechanism 20 are disposed on the fixing seat mechanism 60 .

[0069] In some embodiments, a slot is provided on the fixed seat mechanism 60, which matches the shape of the pole lug support block mechanism 50, and the pole lug support block mechanism 50 can be embedded in the slot of the fixed seat mechanism 60; the pole lug support block on the pole lug support block mechanism 50 can move along the slot on the fixed seat mechanism 60, thereby realizing the position adjustment of the pole lug support block mechanism 50, ensuring that the pole lug support block mechanism 50 can still accurately support the pole lug on the battery cell 30 under the production requirements of different process parameters of the battery cell 30, thereby improving the practicality and flexibility of the pole lug positioning device.

[0070] See also Figure 5 , Figure 5 The structure diagram of a tab positioning device provided in an embodiment of the present application includes a tab positioning mechanism 10 , a first driving mechanism 20 , a second driving mechanism 40 , a tab support mechanism 50 , a fixing seat mechanism 60 , a supporting seat mechanism 70 and a third driving mechanism 80 .

[0071] It should be understood that the tab positioning mechanism 10 , the first driving mechanism 20 , the second driving mechanism 40 , the tab support mechanism 50 , and the fixing seat mechanism 60 have been described above, and will not be described again here to avoid repetition.

[0072] Exemplarily, the support seat mechanism 70 is a base mechanism of the tab positioning device, used to support other mechanisms of the tab positioning device; wherein the support seat mechanism 70 includes a main frame 71 and a movable guide rail 72, the movable guide rail 72 is mounted on the main frame 71, and the fixed seat mechanism 60 is mounted on the movable guide rail 72. It should be noted that the fixed seat mechanism 60 can move along the movable guide rail 72.

[0073] Exemplarily, the tab positioning mechanism 10, the first drive mechanism 20, the second drive mechanism 40, and the tab support mechanism 50 are all directly or indirectly fixed to the fixed seat mechanism 60; so that when the fixed seat mechanism 60 moves left and right along the movable guide rail 72, the tab positioning mechanism 10 and the tab support mechanism 50 can also move accordingly.

[0074] Exemplarily, the third driving mechanism 80 is respectively connected to the supporting seat mechanism 70 and the fixing seat mechanism 60 , and is used to drive the fixing seat mechanism 60 to slide along the moving guide rail 72 .

[0075] In some embodiments, the third driving mechanism 80 is an actuator, which may be a pneumatic actuator, a hydraulic actuator, or an electric actuator.

[0076] In some implementation scenarios, the battery cell 30 is conveyed to the tab positioning device before the folding tooling in the packaging machine performs the battery cell shelling and aluminum film folding processes; during the conveying process of the battery cell 30, due to the influence of conveying accuracy or other factors, the tabs of the battery cell 30 may not be correctly delivered to the tab positioning mechanism 10; therefore, the third driving mechanism 80 drives the tab positioning mechanism 10 and the tab support mechanism 50 to move along the direction of the moving guide rail, thereby adjusting the left and right positions of the tab positioning mechanism 10 and the tab support mechanism 50 to ensure that the tabs of the battery cell 30 are correctly delivered to the tab positioning mechanism 10.

[0077] In some implementation scenarios, the tab positioning device is used in a battery packaging machine, for example, in a folding tool in the packaging machine to shell the battery cell 30 and fold the aluminum film. Specifically, before the folding tooling performs cell shelling and aluminum film folding on the battery cell 30, the second drive mechanism 40 and the third drive mechanism 80 adjust the positions of the tab positioning mechanism 10 and the tab support mechanism 50 so that the first tab 31 and the second tab 32 of the battery cell 30 are in the correct position; after the two tabs of the battery cell 30 are fed into the tab positioning mechanism, the second drive mechanism 40 moves downward, thereby driving the limiter on the tab positioning mechanism to move downward to prevent the tabs of the battery cell 30 from tilting upward; then the first drive mechanism 20 drives the first tab clamp 11 and the second tab clamp 12 to approach each other, and the first clamping edge 111 and the third clamping edge 121 to approach each other, thereby clamping and fixing the first tab 31; the second clamping edge 112 and the fourth clamping edge 122 to approach each other to clamp and fix the second tab 32; at this time, the tab support mechanism 50 supports the tabs of the battery cell 30 to prevent the first tab 31 and the second tab 32 from tilting downward. After the two tabs of the battery cell 30 are fixed, the folding tooling performs the process of shelling the battery cell 30 and folding the aluminum film, thereby avoiding the displacement of the tabs, achieving a high-quality aluminum film folding effect, ensuring the packaging quality, and improving the production efficiency and production quality.
