[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0026] Reference below Figure 1-Figure 2 A pole group processing device 100 according to an embodiment of the utility model is described, which integrates a hot pressing mechanism 21, a Hipot testing mechanism 22 and a gluing mechanism 23, realizes the integrated setting of various functional mechanisms, improves the integration degree between various mechanisms, reduces the rotation speed distance, reduces the transportation cost and equipment cost, and improves production efficiency.
[0027] like Figure 1-Figure 2 As shown, a pole group processing device 100 according to an embodiment of the utility model comprises: a frame 5, a hot pressing mechanism 21, a Hipot testing mechanism 22, a gluing mechanism 23, a temporary placement platform 31 and a deviation correction platform 32.
[0028] The frame 5 serves as the bottom support and installation base of the entire electrode group processing device 100, and the hot pressing mechanism 21, the Hipot testing mechanism 22, the glue sticking mechanism 23, the temporary placement platform 31 and the deviation correction platform 32 are all installed above the frame 5. Specifically, Figure 2 As shown, a plurality of legs 51 are provided at the bottom of the frame 5, so that the frame 5 and the components mounted thereon are spaced apart from the ground. Thus, the main mechanisms are integrated on the frame 5, so that the mechanisms of the pole group processing device 100 form a whole, and the spacing between the mechanisms is small, which is conducive to rapid transportation and reduces the overall footprint.
[0029] The hot pressing mechanism 21 is used to hot press the electrode group. The hot pressing mechanism 21 can be provided with a hot press lower pressure electric cylinder. After the electrode group is placed on the hot pressing mechanism 21, the hot press lower pressure electric cylinder can be used to apply pressure to the electrode group so that the various components of the electrode column are squeezed against each other, thereby making the structure of the electrode group more compact.
[0030] The Hipot test mechanism 22 is used to test the electrode group after hot pressing. It should be noted that the Hipot test mechanism 22 in the utility model is not only integrated with the function of performing Hipot (full name "high potential", meaning high potential tester) test on the electrode group to detect whether there is a short circuit in the electrode group, but also used to realize the thickness detection of the electrode group, so that the qualified condition of the electrode group can be actively detected by the Hipot test mechanism 22. For example, when it is detected that the electrode group has unclassified products, it can be rejected in time to ensure the qualified rate of the final product. In other words, the Hipot test mechanism 22 in the utility model can integrate the functions of Hipot test and thickness test, which is conducive to reducing the number of single test mechanisms, reducing the setting cost, and improving the structural integration.
[0031] It should be noted that a Hipot test platform is provided at the Hipot test mechanism 22, and the electrode group can be placed on the Hipot test platform for testing and thickness measurement.
[0032] The gluing mechanism 23 is used to glue the electrode group after the test, that is, the electrode group after the test can be glued by the gluing mechanism 23. It should be noted that after the test, qualified products can be glued by the gluing mechanism 23, and unqualified products can be discarded. In this way, qualified products can be protected by glue, thereby improving the safety of the electrode group.
[0033] Furthermore, the frame 5 is also provided with a temporary placement platform 31 and a correction platform 32. The pole group is suitable for being placed on the temporary placement platform 31 after hot pressing. A correction mechanism is provided at the correction platform 32. The pole group is suitable for being placed on the correction platform 32 before testing and being corrected by the correction mechanism. That is to say, after the pole group is hot pressed by the hot pressing mechanism 21, the pole group that has been hot pressed can be temporarily stored on the temporary placement platform 31. It should be noted that the hot pressing mechanism 21 can simultaneously hot press multiple pole groups, that is, the hot pressing effect of the pole group is relatively high. Therefore, the pole group after hot pressing can be temporarily stored on the temporary placement platform 31, reducing the processing pressure of the rear mechanism.
[0034] Also, after the hot pressed electrode group is placed on the temporary placement platform 31 and before entering the Hipot test mechanism 22, the electrode group can be corrected by the correction mechanism. It is understandable that the electrode group undergoes multiple processes during the processing, and the position error generated in each process will be accumulated, which may cause its position deviation to be too large. Therefore, before entering the Hipot test mechanism 22, it can be placed on the correction platform 32 for active correction, so that the electrode group maintains a reliable position state.
[0035] According to the pole group processing device 100 of the embodiment of the utility model, the integrated setting of the hot pressing mechanism 21, the Hipot testing mechanism 22 and the gluing mechanism 23 can be realized, the transportation distance between the various mechanisms can be reduced, the cost required during the transportation process can be reduced, and the production efficiency can be improved. In addition, the overall occupied area of the pole group processing device 100 is small and easy to place.
[0036] In some embodiments, Figure 1 and Figure 2 As shown, the electrode group processing device 100 also includes: a QR code pasting mechanism 24, which is used to paste a QR code on the electrode group. It should be noted that the QR code pasting mechanism 24 can be set at a position close to the Hipot test mechanism 22, so that after the electrode group is tested by the Hipot test mechanism 22, the QR code can be further pasted to achieve labeling processing of each electrode group, which is convenient for the subsequent identification of the electrode group.
[0037] In some embodiments, the electrode assembly processing device 100 further includes a hot pressing section blanking robot 14. Figure 1 and Figure 2 As shown, the gluing mechanism 23, the QR code affixing mechanism 24 and the hot pressing section unloading robot 14 are located in the lower left corner area of the frame 5, and the hot pressing section unloading robot 14 can actively grab the pole group at the Hipot test platform, and after grabbing, it can be transferred to a position close to the gluing mechanism 23 and the QR code affixing mechanism 24.
[0038] Among them, the hot pressing section blanking manipulator 14 grabs the tested pole group to the gluing mechanism 23 and the QR code sticking mechanism 24. The gluing mechanism 23 and the QR code sticking mechanism 24 are suitable for simultaneously gluing and sticking QR codes to the pole group clamped by the hot pressing section blanking manipulator 14. Therefore, the gluing process and the QR code sticking process can be carried out at the same time, reducing the time cost required for both. It should be noted that in the process of gluing and QR code sticking, the pole group is grabbed by the hot pressing section blanking manipulator 14 and is in a clamping state, and there is no need to set up a separate gluing platform. Such a setting not only saves the space of the gluing platform, but also saves the time of placing the battery cell into the gluing platform and removing it from the gluing platform, greatly improving the work efficiency.
[0039] In some embodiments, the hot pressing section unloading robot 14 is located in the unloading area of the frame 5, and the unloading area of the frame 5 also includes an unloading section 41 and a cache NG belt 42. The hot pressing section unloading robot 14 is also used to transfer the electrode group to the unloading section 41 or the cache NG belt 42. That is to say, after the electrode group is glued and QR-coded, it can be classified and output according to whether the electrode group is qualified, such as grabbing the electrode group that has passed the test to the unloading section 41 to achieve good product output, or conveying the unqualified products to the cache NG belt 42 for collection.
[0040] Furthermore, the hot pressing section blanking robot 14 has a gantry support structure 141, and the hot pressing section blanking robot 14 is installed and supported on the frame 5 through the gantry support structure 141. Therefore, the hot pressing section blanking robot 14 can have two supporting positions relative to the frame 5, thereby ensuring that the supporting state of the hot pressing section blanking robot 14 is relatively stable. In other words, by setting the gantry support structure 141 to support the hot pressing section blanking robot 14 at two points, compared with supporting it through a cantilever structure, the stability of the support on both sides is better, which can avoid the deformation of the material, and thus it is not easy for the horizontal position of the robot to change.
[0041] In some embodiments, Figure 1 and Figure 2 As shown, the pole group processing device 100 further includes: a loading mechanism 11 and a unloading mechanism 13 .
[0042] Among them, the loading mechanism 11 is provided with a loading robot 111, which is movable relative to the frame 5, and the loading robot 111 is used to grab the stacked pole group to the hot pressing mechanism 21, and the unloading mechanism 13 is provided with a unloading robot 131, which is movable relative to the frame 5, and the unloading robot 131 is used to grab the pole group at the hot pressing mechanism 21 to the temporary storage platform 31.
[0043] Specifically, Figure 1 As shown, the loading manipulator 111 is located on the right side of the hot pressing mechanism 21, and the loading manipulator 111 can move, rotate and rise and fall relative to the frame 5. The loading manipulator 111 can be installed on the frame 5 through a slide rail, and a rotating structure is set to drive the loading manipulator 111 to rotate, so that the loading manipulator 111 can move to a position close to the hot pressing mechanism 21 after clamping the electrode group, and then the loading manipulator 111 can be rotated and moved, so that the electrode group clamped by the loading manipulator 111 can be transported to the hot pressing space of the hot pressing mechanism 21.
[0044] And, if Figure 1As shown, the unloading manipulator 131 is located on the left side of the hot pressing mechanism 21, and the unloading manipulator 131 can move, rotate and lift relative to the frame 5. Among them, the unloading manipulator 131 can be installed on the frame 5 through a slide rail, and a rotating structure is set to drive the unloading manipulator 131 to rotate, so that the unloading manipulator 131 can extend into the hot pressing space to clamp the electrode group, and transfer the electrode group to the temporary storage platform 31 for storage through rotation and movement. Specifically, in actual operation, the unloading manipulator 131 extends to the right into the hot pressing mechanism 21 to grab the electrode group, the clamping claw extends and retreats, rotates 180 degrees, and then moves to the temporary storage platform 31 for placement, and the unloading manipulator 131 returns to the hot pressing position.
[0045] It should be noted that the loading robot 111 and the unloading robot 131 can realize actions such as rotation, movement, and lifting, and the specific motion structure can be realized by a conventional rotating structure and a guide rail slider matching structure.
[0046] In some embodiments, the loading mechanism 11 and the unloading mechanism 13 are respectively located on both sides of the hot pressing mechanism 21. Specifically, as shown in FIG. Figure 1 and Figure 2 As shown in , the loading mechanism 11 may be located on the right side of the hot pressing mechanism 21, and the unloading mechanism 13 may be located on the left side of the hot pressing mechanism 21, that is, the right side of the hot pressing mechanism 21 is the loading side, and the left side is the unloading side.
[0047] Furthermore, the feeding mechanism 11 , the unloading mechanism 13 and the hot pressing mechanism 21 are all arranged in two groups and matched one by one, and each group has two hot pressing mechanisms 21 .
[0048] Specifically, Figure 1 As shown, there are two feeding mechanisms 11, and the two feeding mechanisms 11 are located in the upper right area and the lower right area of the frame 5; there are four hot pressing mechanisms 21, and two of them form a group, and the four hot pressing mechanisms 21 of the two groups are arranged along Figure 1 at the same time, there are two unloading mechanisms 13, and the two unloading mechanisms 13 are located in the middle area of the left and right directions of the frame 5 and are located on the left side of the hot pressing mechanism 21.
[0049] That is, one loading mechanism 11 and one unloading mechanism 13 are respectively located on the left and right sides of the upper group of hot pressing mechanisms 21, and another unloading mechanism 13 and another unloading mechanism 13 are respectively located on the left and right sides of the lower group of hot pressing mechanisms 21. Among them, the loading manipulator 111 and the unloading manipulator 131 can move between multiple positions in space.
[0050] In some embodiments, the pole group processing device 100 also includes: a transport mechanism 12, the transport mechanism 12 is provided with a transport robot 121, the transport robot 121 is movable relative to the frame 5, and the transport robot 121 is used to grab the pole group on the temporary platform 31 to the correction platform 32 and to transport the pole group after correction to the Hipot testing mechanism 22.
[0051] Specifically, Figure 1 As shown, the transport mechanism 12 is located between the temporary placement platform 31 and the hot pressing mechanism 21, and the transport robot 121 can rotate and move relative to the frame 5 to achieve movement between multiple positions in the space.
[0052] And, in actual work, the correction process is that the handling robot 121 clamps the pole group on the temporary platform 31 and moves it to the position of the space above the correction platform 32. A camera is provided in the space below the correction platform 32 to take pictures of the position of the pole group. At this time, the correction platform 32 is in a retracted state, and its driving motor drives it to move backward so that the camera below it that is blocked by it can take pictures of the pole group. When the picture is taken, the correction platform 32 is driven by the driving motor to move forward to the bottom of the pole group. The handling robot 121 places the pole group on the correction platform 32, and the correction platform 32 is corrected according to the original position. After the correction is completed, the handling robot 121 of the temporary platform 31 grabs the pole group, rotates 90 degrees, and drops it on the motion module of the Hipot testing mechanism 22. The motion module transports the pole group to the Hipot testing platform to start the Hipot test and thickness measurement.
[0053] In some embodiments, the hot pressing mechanism 21 has a multi-layer placement piece, and the multi-layer placement piece is used to place multiple electrode groups respectively. Specifically, the placement piece can be constructed as a placement plate 211, and there are multiple placement plates 211, and multiple placement plates 211 are arranged in sequence along the up and down direction, and the electrode group can be placed above the placement plate 211. Among them, two adjacent placement plates 211 can be relatively movable, such as being connected by a pull rod 212. It should be noted that the pull rods 212 between each placement plate 211 have the same length. After moving upward to a certain stroke, the upper placement plate 211 of the two adjacent placement plates 211 can drive the lower placement plate 211 to move upward through the pull rod 212, and a certain gap is maintained between the two placement plates 211 for placing the electrode group.
[0054] In actual design, of the two adjacent placement plates 211, the placement plate 211 located on the upper side can be connected to the upper end of the pull rod 212, and the lower part of the pull rod 212 can be inserted into the placement plate 211 located on the lower side, and a support plate is provided at the lower end of the pull rod 212 to support the placement plate 211 located on the lower side, so that when the placement plate 211 located on the upper side moves upward, the support plate can drive the placement plate 211 located on the lower side to move upward. The gravity of the placement plate 211 can be used to realize automatic falling, and there is no need to provide a separate counterweight block, thereby reducing the installation cost.
[0055] Among them, two hot pressing driving members are arranged on the top of each hot pressing mechanism 21, and the two hot pressing driving members are spaced apart and are suitable for hot pressing the electrode group at the same time. Specifically, the hot pressing driving member can be configured as a hot pressing electric cylinder, so that the two hot pressing electric cylinders can actively hot press the electrode group at the same time, so that the pressure distribution of the hot pressing mechanism 21 is more uniform. For example, two hot pressing electric cylinders with a pressure of 15 tons can be arranged, and the cost is lower than that of a hot pressing electric cylinder with a pressure of 30 tons.
[0056] In some embodiments, there are multiple temporary platforms 31, and the correction platform 32 is parallel to and spaced apart from the multiple temporary platforms 31. Figure 1 As shown, there are four temporary platforms 31, and the deviation correction platform 32 is connected to the four temporary platforms 31 along the Figure 1 They are distributed parallel and spaced apart in the upper and lower directions.
[0057] Combine the following Figure 1 Describe the process flow of the electrode group processing device of the embodiment of the utility model:
[0058] First, the loading mechanism 11 grabs 4 battery cells from the stacking table and rotates and transfers them to the hot pressing mechanism 21. The hot pressing mechanism 21 performs hot pressing with constant pressure, temperature and hot pressing time. After the hot pressing is completed, the unloading mechanism 13 moves the hot-pressed battery cells out and rotates and transfers them to the temporary storage platform 31. The handling robot 121 moves each battery cell to the correction platform 32 in turn. After the correction is completed, the handling robot 121 rotates 90 degrees and places the electrode group on the mobile module of the Hipot testing mechanism 22. The mobile module moves the electrode group to the Hipot testing platform for hipot testing and thickness measurement. After completion, the hot pressing section unloading robot 14 grabs the electrode group to the gluing mechanism 23 for gluing. After gluing is completed, the hot pressing section unloading robot 14 moves the battery cell with the tape to the QR code sticking mechanism 24, and sticks the tape with the QR code on the surface of the battery cell. After completion, the hot pressing section unloading robot 14 continues to unload the battery cell to the downstream logistics line, and the equipment operation is completed. If there is a fault in the downstream logistics line or the battery cell is NG, the battery cell will be placed on the buffer NG belt 42.
