Description

Technical Field

[0001] This application relates to the field of lithium battery production equipment, specifically a cell patching device. Background Technology

[0002] A battery cell module is formed by stacking multiple battery cells. Before stacking the battery cells into a battery cell module, spacers (such as mica sheets) for insulation and adhesion need to be pre-attached to the battery cells. Adjacent battery cells are bonded together by the spacers. To improve the chip mounting efficiency, the battery cell mounting device picks up two spacers from the chip picking station and then simultaneously attaches the two spacers to two battery cells located at the mounting station.

[0003] The existing cell mounting device has the problem that it cannot adjust the spacing between the two spacers picked up. When the spacing between the two spacers at the pick-up station is less than the spacing between the two cells at the mounting station, the cell mounting device cannot synchronously mount the two spacers onto the two cells at the mounting station after picking up the spacers at the pick-up station. Utility Model Content

[0004] To address the aforementioned technical problems, this application provides a cell patching device, the detailed technical solution of which is as follows:

[0005] A battery cell mounting device includes a support, a top mount, a rotating plate, a rotation drive mechanism, and a conveying mechanism, wherein:

[0006] The top seat and the rotary drive mechanism are both mounted on the bracket. The rotating plate is connected to the movable part of the rotary drive mechanism and is located below the top seat. The side wall of the top seat is provided with a continuous and closed variable pitch groove.

[0007] The conveying mechanism includes a fixed base, a first adsorption component, a second adsorption component, and a pitch-changing component. The fixed base is fixedly connected to the rotating plate. The first adsorption component and the second adsorption component are both connected to the fixed base. The first adsorption component and the second adsorption component are each used to adsorb a spacer. The pitch-changing component is set on the fixed base. The top of the pitch-changing component is located in the pitch-changing groove and can slide along the pitch-changing groove. The pitch-changing component is drivenly connected to the first adsorption component and the second adsorption component.

[0008] The rotary drive mechanism is used to drive the rotary plate to rotate relative to the top seat, so as to drive the conveying mechanism to rotate. The rotation path of the conveying mechanism is provided with at least a pick-up station and a placement station.

[0009] When the transport mechanism rotates from the pick-up station toward the placement station, the pitch groove triggers the pitch component, causing the pitch component to drive the first adsorption component and the second adsorption component to slide and separate to both sides.

[0010] When the carrying mechanism rotates from the taking piece work station to the pasting piece work station, the variable distance groove triggers the variable distance assembly, so that the variable distance assembly drives the first adsorption assembly and the second adsorption assembly to slide to the middle and close to each other.

[0011] The electric core pasting device provided in the application, in the process of carrying two pieces of separator from the taking piece work station to the pasting piece work station by the two adsorption assemblies of the carrying mechanism, the variable distance groove and the variable distance assembly cooperate to adjust the distance between the suction cups of the two adsorption assemblies, so that the distance between the two pieces of separator matches the distance between the two electric cores at the pasting piece work station, and finally ensures that the two pieces of separator can be pasted on the two electric cores at the pasting piece work station synchronously, improving the pasting effect.

[0012] In some embodiments, the first adsorption assembly and the second adsorption assembly each include a mounting plate and a suction cup mounted at the lower end of the mounting plate, wherein:

[0013] The mounting plate of the first adsorption assembly and the mounting plate of the second adsorption assembly are connected to the fixed seat, and the suction cup of the first adsorption assembly and the suction cup of the second adsorption assembly are horizontally slidably connected to the corresponding mounting plate, and the suction cup of the first adsorption assembly and the suction cup of the second adsorption assembly are respectively used to adsorb one piece of separator;

[0014] The variable distance assembly includes a transmission part and a follower wheel, wherein the follower wheel is installed at the top end of the transmission part and located in the variable distance groove, and the transmission part is in transmission connection with the suction cup of the first adsorption assembly and the suction cup of the second adsorption assembly, respectively;

[0015] When the carrying mechanism rotates from the taking piece work station to the pasting piece work station, the variable distance groove triggers the transmission part through the follower wheel, so that the transmission part drives the suction cup of the first adsorption assembly and the suction cup of the second adsorption assembly to slide apart to both sides;

[0016] When the carrying mechanism rotates from the taking piece work station to the pasting piece work station, the variable distance groove triggers the transmission part through the follower wheel, so that the transmission part drives the suction cup of the first adsorption assembly and the suction cup of the second adsorption assembly to slide apart to both sides;

[0017] Since the follower wheel installed at the top end of the transmission part is located in the variable distance groove, the suction cup of the first adsorption assembly and the suction cup of the second adsorption assembly are respectively in transmission connection with the transmission part. In this way, when the carrying mechanism rotates between the taking piece work station and the pasting piece work station, the follower wheel is limited in the variable distance groove and slides along the variable distance groove.

[0018] By differentiating the variable distance grooves at the picking position and the pasting position, when the follower wheel slides from the variable distance groove at the picking position to the variable distance groove at the pasting position, the distance between the follower wheel and the rotation center of the rotating plate changes, thereby triggering the transmission part to drive the suction cups of the first and second suction assemblies to slide apart; similarly, when the follower wheel slides from the variable distance groove at the pasting position to the variable distance groove at the picking position, the distance between the follower wheel and the rotation center of the rotating plate changes, thereby triggering the transmission part to drive the suction cups of the first and second suction assemblies to slide together.

[0019] In some embodiments, the top base comprises a top plate and a variable distance cylinder, wherein the variable distance cylinder is connected to the bottom of the top plate, the variable distance groove is arranged on the side wall of the variable distance cylinder, the variable distance groove comprises a horizontal section and a concave section, the picking position corresponds to the middle of the horizontal section, and the pasting position corresponds to the middle of the concave section;

[0020] When the follower wheel slides along the horizontal section, the vertical distance between the follower wheel and the top plate remains a first distance; when the follower wheel slides from the horizontal section to the concave section and along the concave section towards the pasting position, the vertical distance between the follower wheel and the top plate gradually increases to a second distance; when the follower wheel slides along the concave section from the pasting position towards the horizontal section, the vertical distance between the follower wheel and the top plate gradually decreases to the first distance;

[0021] The transmission part comprises a follower plate, a connecting plate, a first push wheel, a second push wheel and a spring, wherein: the follower plate is connected to the fixed seat in a vertically slidable manner, the first end of the connecting plate is fixedly connected to the upper end of the follower plate, the follower wheel is installed on the second end of the connecting plate, the opposite sides of the lower end of the follower plate are formed with a first push surface and a second push surface, and the interval between the first push surface and the second push surface in the horizontal direction gradually decreases from top to bottom;

[0022] The first push wheel is installed on the suction cup of the first suction assembly, the second push wheel is installed on the suction cup of the second suction assembly, and the two ends of the spring are connected to the suction cup of the first suction assembly and the suction cup of the second suction assembly respectively, and the spring is used to pull the suction cup of the first suction assembly and the suction cup of the second suction assembly towards the middle, so that the first push wheel and the second push wheel are elastically pressed against the first push surface and the second push surface respectively;

[0023] When the follower wheel slides along the concave section towards the pasting position, the follower plate slides downwards relative to the fixed seat, thereby driving the suction cups of the first and second suction assemblies to slide apart;

[0024] When the follower wheel slides along the concave section from the pasting position towards the horizontal section, the follower plate slides upwards relative to the fixed seat, thereby driving the transmission part to drive the suction cups of the first and second suction assemblies to slide together.

[0025] By setting the variable distance groove to be formed by the butt joint of the horizontal section and the concave section, the vertical distance between the variable distance groove at the picking position and the variable distance groove at the pasting position and the rotation center of the rotating plate is respectively a smaller first distance and a larger second distance.

[0026] In this way, when the follower wheel slides from the variable distance groove at the picking position to the variable distance groove at the pasting position, the follower wheel slides downward into the concave section, the follower plate slides downward relative to the fixed seat, thereby pushing the first and second pushing wheels to the left and right through the first and second pushing surfaces, and finally making the suction cups of the first and second suction assemblies slide apart to the left and right. When the follower wheel slides from the variable distance groove at the pasting position to the variable distance groove at the picking position, the follower wheel rises and returns to the horizontal section, the follower plate rises to the original position, the spring rebounds and pulls the suction cups of the first and second suction assemblies to the middle, making the suction cups of the first and second suction assemblies slide to the middle.

[0027] In some embodiments, the rotating drive mechanism includes a base, a rotating drive member, and a rotating shaft, wherein: the base is arranged on the support below the rotating plate, and the rotating plate is rotatably connected to the base through a plane bearing; the rotating drive member is arranged on the lower side of the base, the lower end of the rotating shaft is connected to the driving end of the rotating drive member, and the upper end of the rotating shaft passes upward through the base and the plane bearing and is connected to the rotating plate; the rotating drive member drives the rotating plate to rotate through the rotating shaft.

[0028] The rotating plate is rotatably connected to the base through a plane bearing, so that the rotating plate can rotate relative to the base, and the stability of the connection between the rotating plate and the base is improved, so that the rotating plate remains horizontal during rotation.

[0029] In some embodiments, the cell pasting device further includes a rotating support and a plurality of support rods, wherein: the rotating support is rotatably arranged on the top of the top seat; the upper ends of the plurality of support rods are connected to the rotating support in a circumferential direction, and the lower ends of the plurality of support rods are connected to the rotating plate in a circumferential direction.

[0030] By arranging the rotating support and the plurality of support rods, the rotating plate is suspended and supported, further ensuring that the rotating plate remains stable during rotation.

[0031] In some embodiments, the mounting plate of the first adsorption assembly and the mounting plate of the second adsorption assembly are both connected to the fixed seat in a lifting and sliding manner; the cell patching device further comprises two lifting driving mechanisms arranged on the top seat, and the two lifting driving mechanisms are respectively arranged corresponding to the patch taking station and the patching station; when the carrying mechanism rotates to the patch taking station or the patching station, the mounting plate of the first adsorption assembly and the mounting plate of the second adsorption assembly are respectively connected to the driving end of the lifting driving mechanism, and the lifting driving mechanism is configured to drive the first adsorption assembly and / or the second adsorption assembly to lift.

[0032] By arranging the lifting driving mechanism at the patch taking station and the patching station respectively, when the carrying mechanism rotates to the patch taking station, the lifting driving mechanism at the patch taking station can drive the first adsorption assembly and / or the second adsorption assembly to lift, so that the first adsorption assembly and / or the second adsorption assembly can take the separator from the patch taking station. When the carrying mechanism rotates to the patching station, the lifting driving mechanism at the patching station can drive the first adsorption assembly and / or the second adsorption assembly to lift, so that the first adsorption assembly and / or the second adsorption assembly can patch the taken separator to the corresponding cell.

[0033] In addition, since the lifting driving mechanism is fixedly arranged on the top plate, it can be connected to and separated from the carrying mechanism, so that the lifting driving mechanism does not need to rotate with the carrying mechanism, thereby reducing the driving load of the rotary driving mechanism. On the other hand, when a plurality of carrying mechanisms are arranged, the lifting driving mechanism can be multiplexed, i.e., it can drive the lifting of any carrying mechanism rotating to the patch taking station or the patching station, without the need to arrange a lifting driving mechanism corresponding to each carrying mechanism, thereby reducing the complexity and cost of the device.

[0034] In some embodiments, the cell patching device further comprises a limiting disc, the limiting disc is arranged below the top seat, a ring-shaped guide channel is formed between the top seat and the limiting disc, and the top seat and the limiting disc are both provided with a avoiding gap corresponding to the position of the lifting driving mechanism; the top of the mounting plate of the first adsorption assembly and the mounting plate of the second adsorption assembly are both provided with a limiting wheel, and the limiting wheel is arranged in the guide channel and can slide along the guide channel.

[0035] The lifting driving mechanism comprises a first lifting driving part and a second lifting driving part arranged side by side, and the movable parts of the first lifting driving part and the second lifting driving part are both arranged at the avoiding gap.

[0036] When the carrying mechanism rotates to the patch taking station or the patching station, the limiting wheel of the first adsorption assembly enters the movable part of the first lifting driving part, and the limiting wheel of the second adsorption assembly enters the movable part of the second lifting driving part, so that the first lifting driving part can drive the first adsorption assembly to lift, and the second lifting driving part can drive the second adsorption assembly to lift.

[0037] By setting the limiting disc below the top base, setting the avoiding gap on the top base and the limiting disc corresponding to the position of the lifting driving mechanism, and setting the lifting driving mechanism to include the first lifting driving part and the second lifting driving part, and the movable part of the first lifting driving part and the second lifting driving part is located at the avoiding gap. In this way, when the carrying mechanism rotates to the piece taking station or the piece pasting station, the first adsorption assembly and the second adsorption assembly can be respectively docked with the first lifting driving part and the second lifting driving part through the corresponding limiting wheels, so that the first lifting driving part and the second lifting driving part independently drive the first adsorption assembly and the second adsorption assembly respectively, thereby meeting the piece taking and pasting requirements in different situations. For example, when the carrying mechanism rotates to the piece pasting station, one of the first adsorption assembly and the second adsorption assembly pastes the taken separator on the corresponding battery cell, and the other of the first adsorption assembly and the second adsorption assembly does not implement the separator pasting.

[0038] In some embodiments, the first lifting driving part and the second lifting driving part have the same structure, the first lifting driving part includes a lifting driving piece, a lifting seat, a limiting block and a supporting plate, wherein: the lifting driving piece is arranged on the top base, the lifting seat is connected to the driving end of the lifting driving piece, the limiting block and the supporting plate are arranged on the lifting seat in a top-to-bottom manner, and the docking channel is formed between the limiting block and the supporting plate; when the carrying mechanism rotates to the piece taking station or the piece pasting station, the limiting wheel of the first adsorption assembly enters the docking channel, and the lifting driving piece drives the lifting seat to lift and drive the first adsorption assembly to lift.

[0039] By setting the first lifting driving part and the second lifting driving part, the first lifting driving part and the second lifting driving part respectively have the docking channel composed of the limiting block and the supporting plate. In this way, when the carrying mechanism rotates to the piece taking station or the piece pasting station, the limiting wheels of the first adsorption assembly and the second adsorption assembly can respectively slide into the docking channels of the first lifting driving part and the second lifting driving part, thereby realizing the docking with the first lifting driving part and the second lifting driving part. When the carrying mechanism leaves the piece taking station or the piece pasting station, the limiting wheels of the first adsorption assembly and the second adsorption assembly respectively slide out of the docking channels of the first lifting driving part and the second lifting driving part, thereby realizing the disengagement from the first lifting driving part and the second lifting driving part.

[0040] In some embodiments, the detection station is further arranged on the rotation path of the carrying mechanism, and the piece taking station, the detection station and the piece pasting station are arranged in sequence along the rotation path of the carrying mechanism; when the carrying mechanism rotates to the piece taking station, the carrying mechanism is configured to pick up two separators from the piece taking station; when the carrying mechanism rotates to the detection station, the detection device at the detection station positions the separators on the carrying mechanism; and when the carrying mechanism rotates to the piece pasting station, the carrying mechanism is configured to paste the separators on the battery cells at the piece pasting station according to the position information of the separators.

[0041] By setting a detection station on the rotating path of the carrying mechanism and setting a detection device on the detection station, positioning of the separator before the pasting is realized, so that the carrying mechanism can paste the separator on the battery cell at the pasting station according to the position information of the separator, and the pasting precision is ensured.

[0042] In some embodiments, the battery cell pasting device is provided with at least three carrying mechanisms; the first carrying mechanism is at the taking station, the second carrying mechanism is at the detection station, and the third carrying mechanism is at the pasting station; when the first carrying mechanism rotates from the taking station to the detection station, the other carrying mechanisms rotate to the next station in turn.

[0043] The taking station, the detection station, and the pasting station each have a carrying mechanism after the rotating plate completes one rotation, so that the three carrying mechanisms can simultaneously implement corresponding taking, detection, and pasting actions, thereby speeding up the work rhythm and improving the battery cell pasting efficiency.

[0044] In some embodiments, the battery cell pasting device is provided with four carrying mechanisms, and the rotating path of the carrying mechanism is further provided with an NG piece unloading station between the pasting station and the taking station; when the carrying mechanism rotates to the NG piece unloading station, the carrying mechanism is configured to place the unqualified separator to the unloading station; the first carrying mechanism is at the taking station, the second carrying mechanism is at the detection station, the third carrying mechanism is at the pasting station, and the fourth carrying mechanism is at the NG piece unloading station.

[0045] The detection device can not only implement positioning on the separator to be pasted, but also implement quality detection on the separator, so that only the qualified separator can be pasted on the battery cell. By setting the NG piece unloading station between the pasting station and the taking station, automatic unloading of the unqualified separator is realized. In addition, the taking station, the detection station, the pasting station, and the NG piece unloading station each have a carrying mechanism after the rotating plate completes one rotation, so that the four carrying mechanisms can simultaneously implement corresponding taking, detection, pasting, and NG piece unloading actions, thereby speeding up the work rhythm and improving the battery cell pasting efficiency.

[0064] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0065] In order to make the above objectives, characteristics and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all the embodiments consistent with the present application. On the contrary, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0066] As described in the background section, the existing battery cell patching device has the problem that it cannot adjust the distance between the two pieces of separator picked up. When the distance between the two pieces of separator at the picking station is smaller than the distance between the two battery cells at the patching station, the battery cell patching device cannot synchronously patch the two pieces of separator to the two battery cells at the patching station after picking up the separator at the picking station.

[0067] In order to solve the above-mentioned problems of the existing battery cell patching device, the present application provides a battery cell patching device. As shown in Figures 1 to 4 The battery cell patching device in the embodiments of the present application comprises a bracket 1, a top seat 2, a rotating plate 4, a rotating drive mechanism 3 and a carrying mechanism 5, wherein:

[0068] The top seat 2 and the rotating drive mechanism 3 are both arranged on the bracket 1, the rotating plate 4 is connected to the moving part of the rotating drive mechanism 3 and located below the top seat 2, and a continuous and closed distance-changing groove 6 is arranged on the side wall of the top seat 2.

[0069] The carrying mechanism 5 comprises a fixed seat 51, a first adsorption assembly 52, a second adsorption assembly 53 and a distance-changing assembly 54, wherein the fixed seat 51 is fixedly connected to the rotating plate 4, the first adsorption assembly 52 and the second adsorption assembly 53 are both connected to the fixed seat 51, the first adsorption assembly 52 and the second adsorption assembly 53 are respectively used for adsorbing one piece of separator 100, the distance-changing assembly 54 is arranged on the fixed seat 51, the top of the distance-changing assembly 54 is located in the distance-changing groove 6 and can slide along the distance-changing groove 6, and the distance-changing assembly 54 is in transmission connection with the first adsorption assembly 52 and the second adsorption assembly 53.

[0070] The rotating drive mechanism 3 is used for driving the rotating plate 4 to rotate relative to the top seat 2, so as to drive the carrying mechanism 5 to rotate, and at least a picking station A and a patching station C are arranged on the rotating path of the carrying mechanism 5.

[0071] When the carrying mechanism 5 rotates from the picking station A towards the patching station C, the distance-changing groove 6 triggers the distance-changing assembly 54, so that the distance-changing assembly 54 drives the first adsorption assembly 52 and the second adsorption assembly 53 to slide apart to both sides.

[0072] When the carrying mechanism 5 rotates from the patching station C towards the picking station A, the distance-changing groove 6 triggers the distance-changing assembly 54, so that the distance-changing assembly 54 drives the first adsorption assembly 52 and the second adsorption assembly 53 to slide towards each other to the middle.

[0073] The optional working process of the battery cell patch device in the embodiment of the application is as follows:

[0074] The rotating driving mechanism 3 drives the rotating plate 4 to rotate, so that the carrying mechanism 5 is turned to the patch taking station A, at this time, the distance between the first adsorption assembly 52 and the second adsorption assembly 53 is the first distance, which matches the distance between the two adjacent patches to be attached at the patch taking station A. For example, the patches to be attached are conveyed to the patch taking station A by the feeding conveying line, and the distance between the two adjacent patches on the feeding conveying line matches the first distance. In this way, it can be ensured that the first adsorption assembly 52 and the second adsorption assembly 53 can adsorb the two adjacent patches at the patch taking station A, wherein the first adsorption assembly 52 and the second adsorption assembly 53 adsorb one patch respectively.

[0075] The rotating driving mechanism 3 drives the rotating plate 4 to rotate, so that the carrying mechanism 5 is turned from the patch taking station A to the patch station C, in the process, the distance changing groove 6 triggers the distance changing assembly 54, so that the distance changing assembly 54 drives the first adsorption assembly 52 and the second adsorption assembly 53 to slide apart. When the carrying mechanism 5 is turned to the patch station C, the distance between the first adsorption assembly 52 and the second adsorption assembly 53 increases to the second distance, so that the distance between the two patches adsorbed by the first adsorption assembly 52 and the second adsorption assembly 53 matches the distance between the two battery cells at the patch station C.

[0076] The first adsorption assembly 52 and the second adsorption assembly 53 respectively attach the adsorbed patches to one of the two battery cells at the patch station C.

[0077] The rotating driving mechanism 3 drives the rotating plate 4 to rotate, so that the carrying mechanism 5 is turned from the patch station C to the patch taking station A, in the process, the distance changing groove 6 triggers the distance changing assembly 54, so that the distance changing assembly 54 drives the first adsorption assembly 52 and the second adsorption assembly 53 to slide together. When the carrying mechanism 5 is turned to the patch taking station A, the distance between the first adsorption assembly 52 and the second adsorption assembly 53 returns to the first distance. Repeat the above process, and the carrying mechanism 5 implements the next round of patch attaching operation.

[0078] It can be seen that, in the electric chip pasting device provided in the embodiment, the first adsorption assembly 52 and the second adsorption assembly 53 of the carrying mechanism 5 adjust the distance between the two pieces of separators 100 and the distance between the two electric cores 100 in the pasting station C by the cooperation of the distance changing groove 6 and the distance changing assembly 54, so that the distance between the two pieces of separators 100 matches the distance between the two electric cores 100 in the pasting station C, and finally ensures that the first adsorption assembly 52 and the second adsorption assembly 53 can synchronously paste the two pieces of separators 100 on the two electric cores in the pasting station C, improving the pasting effect. In addition, the driving part for driving the first adsorption assembly 52 and the second adsorption assembly 53 to change the distance is not additionally arranged, reducing the cost of the equipment.

[0079] Optionally, the first adsorption assembly 52 and the second adsorption assembly 53 each include a mounting plate 521 and a suction cup 522 mounted at the lower end of the mounting plate 521.

[0080] The mounting plate 521 of the first adsorption assembly 52 and the mounting plate 521 of the second adsorption assembly 53 are connected to the fixed seat 51, and the suction cup 522 of the first adsorption assembly 52 and the suction cup 522 of the second adsorption assembly 53 are horizontally slidably connected to the corresponding mounting plate 521, and the suction cup 522 of the first adsorption assembly 52 and the suction cup 522 of the second adsorption assembly 53 are respectively used to adsorb one piece of separator 100.

[0081] The distance changing assembly 54 includes a transmission part 541 and a follower wheel 542, wherein the follower wheel 542 is mounted at the top end of the transmission part 541 and located in the distance changing groove 6, and the transmission part 541 is in transmission connection with the suction cup 522 of the first adsorption assembly 52 and the suction cup 522 of the second adsorption assembly 53, respectively.

[0082] When the carrying mechanism 5 rotates from the taking station A to the pasting station C, the distance changing groove 6 triggers the transmission part 541 through the follower wheel 542, so that the transmission part 541 drives the suction cup 522 of the first adsorption assembly 52 and the suction cup 522 of the second adsorption assembly 53 to slide apart to both sides.

[0083] When the carrying mechanism 5 rotates from the pasting station C to the taking station A, the distance changing groove 6 triggers the transmission part 541 through the follower wheel 542, so that the transmission part 541 drives the suction cup 522 of the first adsorption assembly 52 and the suction cup 522 of the second adsorption assembly 53 to slide to the middle.

[0084] It can be seen that, since the follower wheel 542 mounted at the top end of the transmission part 541 is located in the distance changing groove 6, the suction cup 522 of the first adsorption assembly 52 and the suction cup 522 of the second adsorption assembly 53 are in transmission connection with the transmission part 541, respectively. In this way, when the carrying mechanism 5 rotates between the taking station A and the pasting station C, the follower wheel 542 is limited in the distance changing groove 6 and slides along the distance changing groove 6.

[0085] Thus, by differentiating the variable distance grooves 6 at the picking station A and the pasting station C, when the follower wheel 542 slides from the variable distance groove at the picking station A to the variable distance groove at the pasting station C, the distance between the follower wheel 542 and the rotation center of the rotating plate 4 changes, thereby triggering the transmission part 541 to drive the suction cups 522 of the first suction assembly 52 and the second suction assembly 53 to slide apart. Similarly, when the follower wheel 542 slides from the variable distance groove at the pasting station C to the variable distance groove at the picking station A, the distance between the follower wheel 542 and the rotation center of the rotating plate 4 changes, thereby triggering the transmission part 541 to drive the suction cups 522 of the first suction assembly 52 and the second suction assembly 53 to slide together.

[0086] In order to provide sufficient installation space for the suction cups 522 of the first suction assembly 52 and the second suction assembly 53, and ensure that the suction cups 522 of the first suction assembly 52 and the second suction assembly 53 can slide together or apart in the horizontal direction, optionally, the mounting plate 521 of the first suction assembly 52 and the mounting plate 521 of the second suction assembly 53 are both L-shaped plates. Taking the mounting plate 521 of the first suction assembly 52 as an example, the vertical part of the mounting plate 521 is connected to the side wall of the fixed seat 51, and the suction cup 522 of the first suction assembly 52 is slidingly connected to the lower surface of the horizontal part of the mounting plate 521, and can slide towards or away from the second suction assembly 54 relative to the horizontal part of the mounting plate 521.

[0087] As shown in Figures 2 to 3 Optionally, the top seat 2 comprises a top plate 21 and a variable distance cylinder 22, wherein the variable distance cylinder 22 is connected to the bottom of the top plate 21, the variable distance groove 6 is arranged around the side wall of the variable distance cylinder 22, and the variable distance groove 6 comprises a horizontal section 61 and a concave section 62. The picking station A is arranged at the middle of the horizontal section 61, and the pasting station C is arranged at the middle of the concave section 62.

[0088] When the follower wheel 542 slides along the horizontal section 61, the vertical distance between the follower wheel 542 and the rotation center of the top plate 21 remains a first distance. When the follower wheel 542 slides from the horizontal section 61 to the concave section 62 and slides along the concave section 62 towards the pasting station C, the vertical distance between the follower wheel 542 and the top plate 21 gradually increases to a second distance. When the follower wheel 542 slides along the concave section 62 from the pasting station C towards the horizontal section 61, the vertical distance between the follower wheel 542 and the top plate 21 gradually decreases to the first distance.

[0089] As shown in Figure 4As shown, the transmission part 541 comprises a follower plate 543, a connecting plate 544, a first push wheel 545, a second push wheel 546 and a spring 547, wherein the follower plate 543 is connected to the fixed seat 51 in a way that it can slide up and down, the first end of the connecting plate 544 is fixedly connected to the upper end of the follower plate 543, the servo wheel 542 is installed on the second end of the connecting plate 544, the opposite sides of the lower end of the follower plate 543 are formed with a first push surface 543a and a second push surface 543b, and the interval between the first push surface 543a and the second push surface 543b in the horizontal direction gradually decreases from top to bottom.

[0090] The first push wheel 545 is installed on the suction disc 522 of the first suction assembly 52, the second push wheel 546 is installed on the suction disc 522 of the second suction assembly 53, and the two ends of the spring 547 are respectively connected to the suction disc 522 of the first suction assembly 52 and the suction disc 522 of the second suction assembly 53, and the spring 547 is used to pull the suction disc 522 of the first suction assembly 52 and the suction disc 522 of the second suction assembly 53 towards the middle, so that the first push wheel 545 and the second push wheel 546 are elastically pressed against the first push surface 543a and the second push surface 543b respectively.

[0091] When the servo wheel 542 slides along the lower concave section 62 towards the patching station C, the servo wheel 542 slides down into the lower concave section 62, the follower plate 543 slides down relative to the fixed seat 51, thereby pushing the first push wheel 545 and the second push wheel 546 to both sides through the first push surface 543a and the second push surface 543b, and finally driving the suction disc 522 of the first suction assembly 52 and the suction disc 522 of the second suction assembly 53 to slide apart to both sides. At the same time, the spring 547 is stretched by pulling.

[0092] When the servo wheel 542 slides along the lower concave section 62 from the patching station C towards the horizontal section, the servo wheel 542 rises and returns to the horizontal section 61, the follower plate 543 slides up relative to the fixed seat 51, the spring 547 rebounds and pulls the suction disc 522 of the first suction assembly 52 and the suction disc 522 of the second suction assembly 53 towards the middle, and finally drives the suction disc 522 of the first suction assembly 52 and the suction disc 522 of the second suction assembly 53 to slide towards each other.

[0093] As Figure 2As shown, optionally, the rotating driving mechanism 3 comprises a base 31, a rotating driving member 32 and a rotating shaft (not shown in the figure), wherein: the base 31 is arranged on the support 1 and below the rotating plate 4, and the rotating plate 4 is rotationally connected to the base 31 through the plane bearing 7. The rotating driving member 32 is arranged on the lower side of the base 31, the lower end of the rotating shaft is connected to the driving end of the rotating driving member 32, the upper end of the rotating shaft is connected to the rotating plate 4 after passing through the base 31 and the plane bearing 7 upwards, and the rotating driving member 32 drives the rotating plate 4 to rotate through the rotating shaft. The rotating driving member 32 may, for example, adopt a servo motor.

[0094] The rotating plate 4 is rotationally connected to the base 31 through the plane bearing 7, so that the rotating plate 4 can rotate relative to the base 31, and the stability of the connection between the rotating plate 4 and the base 31 is improved, so that the rotating plate 4 remains in a horizontal state during rotation.

[0095] Optionally, the battery cell patch device in the embodiment of the application further comprises a rotating support 110 and a plurality of support rods 120, wherein: the rotating support 110 is rotationally arranged on the top of the top seat 2. The upper ends of the plurality of support rods 120 are connected to the rotating support 110 in a circumferential direction, and the lower ends of the plurality of support rods 120 are connected to the rotating plate 4 in a circumferential direction. By arranging the rotating support 110 and the plurality of support rods 120, the rotating plate 4 is suspended and supported, further ensuring that the rotating plate 4 remains stable during rotation.

[0096] When the carrying mechanism 5 rotates to the patch taking station A, there will be a height difference between the first and second adsorption assemblies 52 and 53 of the carrying mechanism 5 and the separator to be adsorbed. Similarly, when the carrying mechanism 5 rotates to the patch mounting station C, there will also be a height difference between the first and second adsorption assemblies 52 and 53 of the carrying mechanism 5 and the battery cell to be mounted with the separator.

[0097] Therefore, optionally, the mounting plate 521 of the first adsorption assembly 52 and the mounting plate 521 of the second adsorption assembly 53 are both connected to the fixed seat 51 in a lifting and sliding manner. For example, the two opposite side walls of the fixed seat 51 are respectively provided with sliding rails extending in the vertical direction, and the mounting plate 521 of the first adsorption assembly 52 and the mounting plate 521 of the second adsorption assembly 53 are respectively connected to the sliding rails of one of the side walls of the fixed seat 51 through sliding blocks.

[0098] The battery cell patch device in the embodiment of the application further comprises two lifting driving mechanisms 8 arranged on the top seat 2, and the two lifting driving mechanisms 8 are respectively arranged corresponding to the patch taking station A and the patch mounting station C.

[0099] When the carrying mechanism 8 rotates to the piece taking station A or the piece pasting station C, the mounting plate 521 of the first adsorption assembly 52 and the mounting plate 521 of the second adsorption assembly 53 are respectively in butt joint with the driving end of the lifting driving mechanism 8, and the lifting driving mechanism 8 is configured to drive the first adsorption assembly 52 and / or the second adsorption assembly 53 to lift.

[0100] By arranging the lifting driving mechanism 8 at the piece taking station A and the piece pasting station C respectively, when the carrying mechanism 5 rotates to the piece taking station A and is in butt joint with the driving end of the lifting driving mechanism 8 at the piece taking station A, the lifting driving mechanism 8 at the piece taking station A can drive the first adsorption assembly 52 and / or the second adsorption assembly 53 to lift, so that the first adsorption assembly 52 and / or the second adsorption assembly 53 take the spacers from the piece taking station.

[0101] The lifting driving mechanism 8 at the piece taking station A can selectively drive one of the first adsorption assembly 52 and the second adsorption assembly 53 to lift, so that one of the first adsorption assembly 52 and the second adsorption assembly 53 takes the spacers from the piece taking station, or can selectively drive the first adsorption assembly 52 and the second adsorption assembly 53 to lift synchronously, so that the first adsorption assembly 52 and the second adsorption assembly 53 synchronously take one piece of spacers from the piece taking station respectively.

[0102] When the carrying mechanism 5 rotates to the piece pasting station C and is in butt joint with the driving end of the lifting driving mechanism 8 at the piece pasting station C, the lifting driving mechanism 8 at the piece pasting station C can drive the first adsorption assembly 52 and / or the second adsorption assembly 53 to lift, so that the first adsorption assembly 52 and / or the second adsorption assembly 53 paste the taken spacers to the corresponding battery cell.

[0103] The lifting driving mechanism 8 at the piece taking station A can selectively drive one of the first adsorption assembly 52 and the second adsorption assembly 53 to lift, so that one of the first adsorption assembly 52 and the second adsorption assembly 53 pastes the taken spacers to the battery cell, or can selectively drive the first adsorption assembly 52 and the second adsorption assembly 53 to lift synchronously, so that the first adsorption assembly 52 and the second adsorption assembly 53 synchronously paste the taken spacers to the corresponding battery cell.

[0104] In addition, since the lifting driving mechanism 8 is fixedly arranged on the top base 2, it can realize butt joint and disengagement with the carrying mechanism 5, so on the one hand, the lifting driving mechanism 8 does not need to rotate with the carrying mechanism 5, thereby reducing the driving load of the rotary driving mechanism 3. On the other hand, when multiple carrying mechanisms 5 are arranged, the lifting driving mechanism 8 realizes multiplexing, that is, the lifting driving mechanism 8 can realize lifting driving of any carrying mechanism 5 currently rotating to the piece taking station A or the piece pasting station C, so it is not necessary to arrange a lifting driving mechanism corresponding to each carrying mechanism 5, thereby reducing the complexity and cost of the device of the present application.

[0105] As Figures 2 to 4 shown, optionally, the battery cell patch device in the present application example further comprises a limiting disc 9, the limiting disc 9 is located below the top base 2, and a ring-shaped guiding channel is formed between the top base 2 and the limiting disc 9, and the top base 2 and the limiting disc 9 are both provided with an avoiding gap 10 at the position corresponding to the lifting driving mechanism 8. Optionally, the limiting disc 9 is horizontally connected to the lower surface of the top base 2 through a plurality of circumferentially arranged connecting rods.

[0106] The top of the mounting plate 521 of the first adsorption assembly 52 and the mounting plate 521 of the second adsorption assembly 53 are both provided with a limiting wheel 523, the limiting wheel 523 is located in the guiding channel and can slide along the guiding channel.

[0107] The lifting driving mechanism 8 comprises a first lifting driving part 81 and a second lifting driving part 82 arranged side by side, and the movable part of the first lifting driving part 81 and the second lifting driving part 82 is located at the avoiding gap 10.

[0108] When the carrying mechanism 5 rotates to the patch taking station A or the patch station C, the limiting wheel 523 of the first adsorption assembly 52 enters the movable part of the first lifting driving part 81, and the limiting wheel 523 of the second adsorption assembly 53 enters the movable part of the second lifting driving part 82, the first lifting driving part 81 can drive the first adsorption assembly 52 to lift, and the second lifting driving part 53 can drive the second adsorption assembly 53 to lift.

[0109] By arranging the limiting disc 9 below the top base 2, and by arranging the lifting driving mechanism 8 to comprise the first lifting driving part 81 and the second lifting driving part 82 capable of implementing independent lifting driving, the present application embodiment realizes that when the carrying mechanism 5 rotates to the patch taking station A or the patch station C, the first adsorption assembly 52 and the second adsorption assembly 53 can be respectively docked with the first lifting driving part 81 and the second lifting driving part 82 of the lifting driving mechanism 8 through the corresponding limiting wheel 523, so that the first lifting driving part 81 and the second lifting driving part 82 independently implement the lifting driving of the first adsorption assembly 52 and the second adsorption assembly 53 respectively, thereby meeting the patch taking and patching requirements under different situations.

[0110] For example, when the carrying mechanism 5 rotates to the patch station C, the first adsorption assembly 52 needs to patch the adsorbed spacer (for example, the qualified silicon wafer confirmed by detection) to the corresponding battery cell, and the second adsorption assembly 53 cannot patch the adsorbed spacer (for example, the unqualified silicon wafer confirmed by detection) to the corresponding battery cell. At this time, the first lifting driving part 81 needs to implement the lifting driving of the first adsorption assembly 52, and the second lifting driving part 82 does not need to implement the lifting driving of the second adsorption assembly 53.

[0111] Optionally, the first lifting driving part 81 and the second lifting driving part 82 have the same structure. Taking the first lifting driving part 81 as an example, as shown in Figure 3 FIG. 8, the first lifting driving part 81 comprises a lifting driving member 811, a lifting seat 812, a limiting block 813 and a support plate 814, wherein the lifting driving member 811 is arranged on the top base 2, the lifting seat 812 is connected to the driving end of the lifting driving member 811, the limiting block 813 and the support plate 814 are arranged on the lifting seat 812 in a top-to-bottom manner, and the abutting channel is formed between the limiting block 813 and the support plate 814.

[0112] When the carrying mechanism 5 rotates to the patch taking station A or the patch pasting station C, the limiting wheel 523 of the first adsorption assembly 52 enters the abutting channel of the first lifting driving part 81, and the lifting driving member 811 of the first lifting driving part 81 drives the lifting seat 812 to lift, so as to drive the first adsorption assembly 52 to lift.

[0113] At the same time, the limiting wheel 523 of the second adsorption assembly 53 enters the abutting channel of the second lifting driving part 82, and the lifting driving member 811 of the second lifting driving part 82 drives the lifting seat 812 to lift, so as to drive the second adsorption assembly 52 to lift.

[0114] It can be seen that, by arranging the first lifting driving part 81 and the second lifting driving part 82, the first lifting driving part 81 and the second lifting driving part 82 respectively have the abutting channel formed by the limiting block 813 and the support plate 814. In this way, when the carrying mechanism 5 rotates to the patch taking station A or the patch pasting station C, the corresponding limiting wheels 523 of the first adsorption assembly 52 and the second adsorption assembly 53 can respectively slide into the abutting channels of the first lifting driving part 81 and the second lifting driving part 82, so as to realize the abutment with the first lifting driving part 81 and the second lifting driving part 82, thereby enabling the first lifting driving part 81 and the second lifting driving part 82 to respectively drive the first adsorption assembly 52 and the second adsorption assembly 53 to lift independently.

[0115] When the carrying mechanism 5 rotates away from the patch taking station A or the patch pasting station C, the corresponding limiting wheels 523 of the first adsorption assembly 52 and the second adsorption assembly 53 respectively slide out of the abutting channels of the first lifting driving part 81 and the second lifting driving part 82, so as to realize the disengagement from the first lifting driving part 81 and the second lifting driving part 82.

[0116] The lifting driving member 811 can be any existing linear driving member capable of driving the lifting seat 812 to lift, such as a cylinder, a lead screw motor, etc.

[0117] As shown in Figure 1 Optionally, the rotating path of the carrying mechanism 5 is further provided with a detection station B, and the patch taking station A, the detection station B and the patch pasting station C are sequentially arranged along the rotating path of the carrying mechanism 5.

[0118] When the carrying mechanism 5 rotates to the taking station A, the carrying mechanism 5 is configured to pick up two spacers from the taking station A. For example, when the carrying mechanism 5 comprises the first suction assembly 52 and the second suction assembly 53, the first suction assembly 52 and the second suction assembly 53 respectively suck one spacer from the taking station A.

[0119] When the carrying mechanism 5 rotates to the detection station B, the detection device arranged at the detection station B performs positioning on the spacers on the carrying mechanism 5, so as to obtain the position information of the two spacers.

[0120] When the carrying mechanism 5 rotates to the pasting station C, the carrying mechanism 5 is configured to paste the spacers to the battery cell at the pasting station according to the position information of the spacers.

[0121] By arranging the detection station B on the rotating path of the carrying mechanism 5 and arranging the detection device at the detection station B, the positioning of the spacers before pasting is realized, so that the carrying mechanism 5 can paste the spacers to the battery cell at the pasting station according to the position information of the spacers, and the pasting precision is ensured.

[0122] Optionally, the detection device is a vision device arranged at the detection station B, and the vision device performs visual angle positioning on the spacers on the carrying mechanism 5, so as to obtain the position information of the spacers on the carrying mechanism 5. The vision device provides the position information of the spacers to the control end of the carrying mechanism 5, and the control end of the carrying mechanism 5 can paste the spacers to the battery cell at the pasting station according to the position information of the spacers.

[0123] Optionally, the battery cell pasting device in the embodiment of the application is provided with at least three carrying mechanisms 5. The first carrying mechanism 5 is at the taking station A, the second carrying mechanism 5 is at the detection station B, and the third carrying mechanism 5 is at the pasting station C. When the rotating drive mechanism 3 drives the rotating plate 4 to rotate and drive the first carrying mechanism 5 to rotate from the taking station A to the detection station B, the other carrying mechanisms 5 are sequentially rotated to the next station, for example, the second carrying mechanism 5 is rotated from the detection station B to the pasting station C, and the third carrying mechanism 5 is rotated from the pasting station C to the next station.

[0124] In this way, after the rotating drive mechanism 3 drives the rotating plate 4 to complete one rotation, the taking station A, the detection station B and the pasting station C are each provided with a carrying mechanism 5. In this way, the three carrying mechanisms 5 can synchronously perform the taking, detection and pasting actions at the stations, so as to speed up the work rhythm and improve the battery cell pasting efficiency of the battery cell pasting device in the embodiment of the application.

[0125] Optionally, the detection device arranged at the detection station B can not only detect and position the separators on the carrying mechanism 5 to obtain the position information of the separators, but also can detect the quality of the separators to determine whether the separators are qualified separators. Of course, only the qualified separators confirmed by the detection device can be attached to the battery cell at the attaching station C.

[0126] Optionally, the battery cell separator attaching device in the embodiment of the application is provided with four carrying mechanisms 5, and the rotating path of the carrying mechanism 5 is further provided with an NG separator discharging station D between the attaching station C and the separator taking station A. When the carrying mechanism 5 rotates to the detection station B, the detection device arranged at the detection station B detects and positions the separators on the carrying mechanism 5 to obtain the position information of the two separators and confirms whether the two separators are qualified separators meeting the quality requirements.

[0127] When the carrying mechanism 5 rotates to the attaching station C, the carrying mechanism 5 attaches the qualified separators to the corresponding battery cells at the attaching station C according to the position information of the qualified separators. The unqualified separators confirmed by the detection are kept on the carrying mechanism 5. When the carrying mechanism 5 rotates to the NG separator discharging station, the carrying mechanism 5 is configured to place the unqualified separators to the NG separator discharging station D. For example, to the separator recycling box at the NG separator discharging station D.

[0128] For example, in one embodiment, when the carrying mechanism 5 rotates to the detection station B, the detection device arranged at the detection station B confirms that the separator on the first adsorption assembly 52 is a qualified separator and the separator on the second adsorption assembly 53 is an unqualified separator by detecting and positioning the two separators on the first adsorption assembly 52 and the second adsorption assembly 53. When the carrying mechanism 5 rotates to the attaching station C, the first adsorption assembly 52 is lowered and attaches the separator thereon to the battery cell, and the second adsorption assembly 53 remains stationary and does not attach the separator. When the carrying mechanism 5 rotates to the NG separator discharging station, the second adsorption assembly 53 places the unqualified separator thereon to the separator recycling box at the NG separator discharging station D.

[0129] It can be seen that by arranging the detection device to be capable of detecting the quality of the separators and arranging the NG separator discharging station D between the attaching station C and the separator taking station A, the automatic discharging of the unqualified separators is realized, and it is ensured that only the qualified separators confirmed by the detection are attached to the battery cells.

[0130] Optionally, when the first carrying mechanism 5 is at the taking position A, the second carrying mechanism 5 is at the detecting position B, the third carrying mechanism 5 is at the pasting position C, and the fourth carrying mechanism 5 is at the NG piece discharging position D. In this way, after the rotating plate 4 driven by the rotating driving mechanism 3 rotates once, the taking position A, the detecting position B, the pasting position C and the NG piece discharging position D each have a carrying mechanism 5, so as to speed up the work rhythm and improve the efficiency of the battery cell pasting device.
