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 plate, a rotary drive mechanism, a rotating plate, and a conveying mechanism, wherein:

[0006] The top plate is mounted on the support frame;

[0007] The rotating plate is rotatably connected to the top plate and located below the top plate. The rotating drive mechanism is set on the top plate and is connected to the rotating plate in a transmission manner. The lower surface of the top plate is provided with a continuous and closed variable pitch groove.

[0008] 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 mounted on the fixed base. The first adsorption component and the second adsorption component are each used to adsorb a spacer. The pitch-changing component is mounted 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 connected to the first adsorption component and the second adsorption component in a transmission manner.

[0009] The rotary drive mechanism is used to drive the rotary plate to rotate relative to the top plate, 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.

[0010] 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.

[0011] When the transport mechanism rotates from the placement station to the pick-up 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 closer to the center.

[0012] In the battery cell mounting device of this application embodiment, during the process of rotating and transporting two spacers picked up from the pick-up station to the mounting station, the variable pitch groove and variable pitch component cooperate to adjust the spacing between the first adsorption component and the second adsorption component, so that the spacing between the two adsorbed spacers matches the spacing between the two battery cells at the mounting station. Ultimately, this ensures that the first adsorption component and the second adsorption component can synchronously attach the two spacers to the two battery cells located at the mounting station, thereby improving the mounting effect.

[0013] In some embodiments, both the first adsorption assembly and the second adsorption assembly include a mounting plate and a suction cup mounted on the lower end of the mounting plate, wherein:

[0014] The mounting plates of the first adsorption component and the second adsorption component are both connected to the fixed base. The suction cups of the first adsorption component and the second adsorption component can be horizontally slidably connected to the corresponding mounting plates. The suction cups of the first adsorption component and the second adsorption component are each used to adsorb a spacer.

[0015] The variable pitch assembly includes a transmission part and a follower wheel. The follower wheel is installed at the top of the transmission part and located in the variable pitch groove. The transmission part is connected to the suction cup of the first adsorption assembly and the suction cup of the second adsorption assembly respectively.

[0016] When the transport mechanism rotates from the pick-up station toward the placement station, the variable pitch groove triggers the transmission unit via the follower wheel, causing the transmission unit to drive the suction cups of the first adsorption component and the second adsorption component to slide apart to both sides.

[0017] When the transport mechanism rotates from the placement station to the pick-up station, the variable pitch groove triggers the transmission unit via the follower wheel, causing the transmission unit to drive the suction cups of the first adsorption component and the second adsorption component to slide closer together.

[0018] Since the follower wheel, mounted at the top of the transmission unit, is located in the pitch groove, the suction cups of the first and second adsorption components are respectively connected to the transmission unit. Thus, when the transport mechanism rotates between the pick-up station and the placement station, the follower wheel is confined within the pitch groove and slides along it.

[0019] By differentiating the pitch grooves located at the wafer pick-up station and the wafer placement station, the following can be achieved: when the follower wheel slides from the pitch groove at the wafer pick-up station toward the pitch groove at the wafer placement station, the distance between the follower wheel and the rotation center of the rotating plate changes, thereby triggering the transmission unit to drive the suction cups of the first and second adsorption components to slide apart. Similarly, when the follower wheel slides from the pitch groove at the wafer placement station toward the pitch groove at the wafer pick-up station, the distance between the follower wheel and the rotation center of the rotating plate changes, thereby triggering the transmission unit to drive the suction cups of the first and second adsorption components to slide closer together.

[0020] In some embodiments, the variable pitch groove includes a first arc segment and a second arc segment, wherein the chip picking station is located at the middle of the first arc segment and the chip placement station is located at the middle of the second arc segment.

[0021] When the follower wheel slides along the first arc segment, the distance between the follower wheel and the rotation center of the rotating plate remains at the first distance;

[0022] As the follower wheel slides from the first arc segment to the second arc segment and slides along the second arc segment toward the placement station, the distance between the follower wheel and the rotation center of the rotating plate gradually increases to the second distance.

[0023] As the follower wheel slides along the second arc segment from the patch placement station toward the first arc segment, the distance between the follower wheel and the rotation center of the rotating plate gradually decreases to the first distance.

[0024] The transmission unit includes a rotating shaft, a follower rod, a spring, a cam, a first pusher wheel, and a second pusher wheel, wherein:

[0025] The rotating shaft is rotatably mounted on the fixed base in the vertical direction. The first end of the follower rod is fixedly connected to the upper end of the rotating shaft, and the follower wheel is rotatably mounted on the second end of the follower rod.

[0026] The cam is fixedly connected to the lower end of the rotating shaft, the first push wheel is installed on the suction cup of the first adsorption component, and the second push wheel is installed on the suction cup of the second adsorption component;

[0027] The two ends of the spring are respectively connected to the suction cups of the first adsorption component and the second adsorption component. The spring is used to pull the suction cups of the first adsorption component and the second adsorption component towards the middle, so that the first push wheel and the second push wheel elastically press against the two side walls of the cam.

[0028] When the follower wheel slides along the second arc segment toward the mounting station, it drives the follower rod to rotate. The follower rod drives the cam to rotate in the first clockwise direction via the rotating shaft, causing the suction cups of the first adsorption component and the second adsorption component to slide and separate to both sides.

[0029] When the follower wheel slides along the second arc segment from the patch placement station toward the first arc segment, it drives the follower rod to rotate. The follower rod drives the cam to rotate in the second clockwise direction via the rotating shaft. The spring drives the suction cups of the first adsorption component and the second adsorption component to slide and move closer to the middle.

[0030] By configuring the variable pitch groove to be formed by the joining of a first arc segment and a second arc segment, the distances between the variable pitch groove located at the wafer pick-up station, the variable pitch groove located at the placement station, and the rotation center of the rotating plate are respectively a smaller first distance and a larger second distance. Thus, when the follower wheel slides from the variable pitch groove at the wafer pick-up station toward the variable pitch groove at the placement station, the distance between the follower wheel and the rotation center of the rotating plate increases. The follower wheel pushes the follower rod to rotate, which in turn drives the rotating shaft and the cam to rotate in a first clockwise direction. The cam ultimately pushes the suction cups of the first and second adsorption components to both sides via the first and second pusher wheels, causing the suction cups of the first and second adsorption components to slide apart. Simultaneously, the spring is stretched and deformed. When the follower wheel slides from the pitch groove at the placement station toward the pitch groove at the take-up station, the distance between the follower wheel and the rotation center of the rotating plate decreases. The follower wheel pushes the follower rod to rotate in the opposite direction, which in turn drives the rotating shaft and cam to rotate in the second clockwise direction. After the spring rebounds, it pulls the suction cups of the first and second adsorption components toward the middle, causing the suction cups of the first and second adsorption components to slide toward the middle.

[0031] In some embodiments, the two sidewalls of the cam are respectively provided with convex arc surfaces extending outward from the middle of the cam. When the cam rotates at a preset angle in the first clockwise direction, the first pusher and the second pusher move from the middle of the cam along the convex arc surface of the cam.

[0032] By providing convex arc surfaces extending outward from the center of the cam on both side walls of the cam, the following is achieved: When the cam rotates at a preset angle in a first clockwise direction, the first and second push rollers slide from the center of the cam to the corresponding convex arc surfaces. This causes the first and second push rollers to be pushed to both sides by the convex arc surfaces on the side walls of the cam, ultimately causing the suction cups of the first and second adsorption components to slide apart. Simultaneously, the spring is stretched and deformed. When the cam rotates in a second clockwise direction, the first and second push rollers slide back to the center of the cam from the corresponding convex arc surfaces, reducing the distance between them. This causes the spring to release pressure and rebound, thereby causing the suction cups of the first and second adsorption components to slide closer together.

[0033] In some embodiments, the transmission unit further includes a mounting body, which is fixedly connected to a fixed base. A rotating shaft is rotatably inserted into the mounting body in a vertical direction, with the upper end of the rotating shaft extending upward through the mounting body and the lower end of the rotating shaft extending downward through the mounting body.

[0034] By setting up the mounting body, the support and limit of the rotating shaft are achieved, preventing the rotating shaft and cam from tilting or deflecting.

[0035] In some embodiments, the rotating plate is rotatably connected to the top plate via a planar bearing; the rotating drive mechanism includes a rotating drive member and a rotating shaft, wherein the rotating drive member is disposed on the upper side of the top plate, the upper end of the rotating shaft is connected to the drive end of the rotating drive member, and the lower end of the rotating shaft passes downward through the top plate and the planar bearing and is connected to the rotating plate; the rotating drive member drives the rotating plate to rotate relative to the top plate via the rotating shaft.

[0036] The rotating plate is rotatably connected to the top plate via a plane bearing, which allows the rotating plate to rotate relative to the top plate and improves the stability of the connection between the rotating plate and the top plate, so that the rotating plate remains horizontal during rotation.

[0037] In some embodiments, the mounting plate of the first adsorption component and the mounting plate of the second adsorption component can be slidably and vertically connected to the fixed base; the cell bonding device also includes two lifting drive mechanisms disposed on the top plate, the two lifting drive mechanisms being respectively disposed for the chip picking station and the bonding station.

[0038] When the transport mechanism rotates to the pick-up station or the placement station, the mounting plate of the first adsorption component and the mounting plate of the second adsorption component are respectively connected to the drive end of the lifting drive mechanism, and the lifting drive mechanism is configured to drive the first adsorption component and / or the second adsorption component to lift.

[0039] By installing lifting drive mechanisms at the wafer picking station and the wafer placement station, when the transport mechanism rotates to the wafer picking station, the lifting drive mechanism at the wafer picking station can drive the first adsorption component and / or the second adsorption component to rise and fall, thereby enabling the first adsorption component and / or the second adsorption component to pick up the spacer from the wafer picking station. When the transport mechanism rotates to the wafer placement station, the lifting drive mechanism at the wafer placement station can drive the first adsorption component and / or the second adsorption component to rise and fall, thereby enabling the first adsorption component and / or the second adsorption component to mount the picked-up spacer onto the corresponding battery cell.

[0040] Furthermore, since the lifting drive mechanism is fixedly mounted on the top plate, it can dock and disengage with the transport mechanism. Therefore, the lifting drive mechanism does not need to rotate with the transport mechanism, thus reducing the drive load on the rotary drive mechanism. On the other hand, when multiple transport mechanisms are provided, the lifting drive mechanism can be reused. That is, the lifting drive mechanism can drive the lifting of any transport mechanism rotating to the pick-up station or the placement station. Therefore, it is not necessary to set up a separate lifting drive mechanism for each transport mechanism, reducing equipment complexity and cost.

[0041] In some embodiments, the cell patching device further includes a limiting plate located below the top plate, and an annular guide channel is formed between the top plate and the limiting plate. Both the top plate and the limiting plate are provided with clearance notches at positions corresponding to the lifting drive mechanism.

[0042] The top of the mounting plate of the first adsorption component and the mounting plate of the second adsorption component are both provided with limiting wheels. The limiting wheels are located in the guide channel and can slide along the guide channel.

[0043] The lifting drive mechanism includes a first lifting drive unit and a second lifting drive unit arranged side by side, and the movable parts of the first lifting drive unit and the second lifting drive unit are both located at the clearance gap.

[0044] When the transport mechanism rotates to the pick-up station or the placement station, the limiting wheel of the first adsorption component enters the movable part of the first lifting drive unit, and the limiting wheel of the second adsorption component enters the movable part of the second lifting drive unit. The first lifting drive unit can drive the first adsorption component to rise and fall, and the second lifting drive unit can drive the second adsorption component to rise and fall.

[0045] By setting a limiting plate below the top plate, and providing clearance notches at the positions of the top plate and the limiting plate corresponding to the lifting drive mechanism, and by configuring the lifting drive mechanism to include a first lifting drive unit and a second lifting drive unit, with the movable parts of both the first and second lifting drive units located at the clearance notches, the first and second adsorption components can dock with the first and second lifting drive units respectively via corresponding limiting wheels when the transport mechanism rotates to the chip picking or placement station. This allows the first and second lifting drive units to independently drive the first and second adsorption components, thus meeting the chip picking and placement requirements under different conditions. For example, when the transport mechanism rotates to the placement station, one of the first and second adsorption components will place the picked-up spacer onto the corresponding battery cell, while the other of the first and second adsorption components may not need to perform spacer placement.

[0046] In some embodiments, the first lifting drive unit and the second lifting drive unit have the same structure. The first lifting drive unit includes a lifting drive component, a lifting seat, a limiting block, and a support plate. The lifting drive component is disposed on the top plate, the lifting seat is connected to the driving end of the lifting drive component, the limiting block and the support plate are disposed on the lifting seat, and a docking channel is formed between the limiting block and the support plate. When the conveying mechanism rotates to the pick-up station or the patching station, the limiting wheel of the first adsorption component enters the docking channel, and the lifting drive component drives the lifting seat to rise and fall, thereby driving the first adsorption component to rise and fall.

[0047] By configuring the first and second lifting drive units, each unit has a docking channel composed of a limiting block and a support plate. Thus, when the transport mechanism rotates to the wafer picking station or the wafer placement station, the limiting wheels corresponding to the first and second adsorption components can slide into the docking channels of the first and second lifting drive units, respectively, thereby achieving docking with them. When the transport mechanism leaves the wafer picking station or the wafer placement station, the limiting wheels corresponding to the first and second adsorption components slide out of the docking channels of the first and second lifting drive units, thereby disengaging from them.

[0048] In some embodiments, a detection station is also provided on the rotation path of the transport mechanism, and the pick-up station, detection station and bonding station are arranged sequentially along the rotation path of the transport mechanism; when the transport mechanism rotates to the pick-up station, the transport mechanism is configured to pick up two spacers from the pick-up station; when the transport mechanism rotates to the detection station, the detection device located at the detection station positions the spacers on the transport mechanism; when the transport mechanism rotates to the bonding station, the transport mechanism is configured to bond the spacers to the battery cell located at the bonding station according to the position information of the spacers.

[0049] By setting up a detection station on the rotation path of the conveying mechanism and installing a detection device at the detection station, the spacer can be positioned before the chip is applied. This allows the conveying mechanism to apply the spacer to the battery cell located at the chip application station based on the spacer's position information, ensuring chip application accuracy.

[0050] In some embodiments, the cell mounting device is provided with at least three transport mechanisms; when the first transport mechanism is at the chip picking station, the second transport mechanism is at the inspection station, and the third transport mechanism is at the chip mounting station; when the first transport mechanism rotates from the chip picking station to the inspection station, the other transport mechanisms rotate sequentially to the next station.

[0051] Each time the rotating plate completes one rotation, there is a conveying mechanism at the chip picking station, the inspection station, and the chip placement station. In this way, the three conveying mechanisms can simultaneously perform the corresponding chip picking, inspection, and placement actions, thereby speeding up the work cycle and improving the efficiency of cell placement.

[0052] In some embodiments, the cell mounting device is provided with four conveying mechanisms, and an NG wafer unloading station is provided on the rotation path of the conveying mechanism between the mounting station and the pick-up station; when the conveying mechanism rotates to the NG wafer unloading station, the conveying mechanism is configured to place the unqualified spacer to the NG wafer unloading station; when the first conveying mechanism is at the pick-up station, the second conveying mechanism is at the inspection station, the third conveying mechanism is at the mounting station, and the fourth conveying mechanism is at the NG wafer unloading station.

[0053] In addition to positioning the spacers to be mounted, the testing device also performs quality checks on the spacers, ensuring that only qualified spacers are mounted onto the battery cells. An NG (non-conforming) spacer unloading station is set up between the mounting station and the pick-up station, enabling automatic unloading of defective spacers. Furthermore, each rotation of the rotary plate is accompanied by a transport mechanism at the pick-up station, testing station, mounting station, and NG spacer unloading station. These four transport mechanisms can simultaneously perform the corresponding pick-up, testing, mounting, and NG spacer unloading actions, thereby accelerating the work cycle and improving battery cell mounting efficiency.

[0075] To make the above-mentioned objects, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0076] As described in the background section, 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 located at the mounting station after picking up the spacers at the pick-up station.

[0077] To address the aforementioned problems of existing cell mounting devices, this application provides a cell mounting device. For example... Figures 1 to 6 As shown, the cell patching device in this embodiment includes a support 1, a top plate 2, a rotary drive mechanism 3, a rotating plate 4, and a conveying mechanism 5, wherein:

[0078] The top plate 2 is mounted on the bracket 1.

[0079] The rotating plate 3 is rotatably connected to the top plate 2 and located below the top plate 2. The rotating drive mechanism 3 is set on the top plate 2 and is connected to the rotating plate 4 in a transmission manner. The lower surface of the top plate 2 is provided with a continuous and closed variable pitch groove 6.

[0080] The conveying mechanism 5 includes a fixed base 51, a first adsorption component 52, a second adsorption component 53, and a variable pitch component 54. The fixed base 51 is fixedly connected to the rotating plate 4. The first adsorption component 52 and the second adsorption component 53 are both disposed on the fixed base 51. The first adsorption component 52 and the second adsorption component 53 are respectively used to adsorb a spacer 100. The variable pitch component 54 is disposed on the fixed base 51. The top of the variable pitch component 54 is located in the variable pitch groove 6 and can slide along the variable pitch groove 6. The variable pitch component 54 is connected to the first adsorption component 52 and the second adsorption component 53 in a transmission connection.

[0081] The rotary drive mechanism 3 is used to drive the rotary plate 4 to rotate relative to the top plate 2, so as to drive the transport mechanism 5 to rotate. The transport mechanism 5 has at least a pick-up station A and a placement station C on its rotation path.

[0082] When the transport mechanism 5 rotates from the pick-up station A toward the placement station C, the pitch groove 6 triggers the pitch component 54, causing the pitch component 54 to drive the first adsorption component 52 and the second adsorption component 53 to slide apart to both sides.

[0083] When the transport mechanism 5 rotates from the placement station C toward the pick-up station A, the pitch groove 6 triggers the pitch component 54, causing the pitch component 54 to drive the first adsorption component 52 and the second adsorption component 53 to slide closer to the center.

[0084] The optional operating process of the cell patching device in this application embodiment is as follows:

[0085] The rotary drive mechanism 3 drives the rotary plate 4 to rotate, causing the transport mechanism 5 to rotate to the pick-up station A. At this time, the distance between the first adsorption component 52 and the second adsorption component 53 is a first distance, which matches the distance between the spacers to be mounted at the pick-up station A. For example, the spacers to be mounted are transported to the pick-up station A by a feeding conveyor line, and the distance between two adjacent spacers on the feeding conveyor line matches the first distance. In this way, it can be ensured that the first adsorption component 52 and the second adsorption component 53 can pick up two adjacent spacers at the pick-up station A, wherein the first adsorption component 52 and the second adsorption component 53 each pick up one spacer.

[0086] The rotary drive mechanism 3 drives the rotary plate 4 to rotate, causing the transport mechanism 5 to rotate from the pick-up station A towards the placement station C. During this process, the pitch changer 6 triggers the pitch changer assembly 54, causing the pitch changer assembly 54 to drive the first adsorption assembly 52 and the second adsorption assembly 53 to slide apart to both sides. When the transport mechanism 5 rotates to the placement station C, the distance between the first adsorption assembly 52 and the second adsorption assembly 53 increases to a second distance, thereby matching the distance between the two spacers picked up by the first adsorption assembly 52 and the second adsorption assembly 53 with the distance between the two cells at the placement station C.

[0087] The first adsorption component 52 and the second adsorption component 53 respectively attach the adsorbed spacer to one of the two cells at the mounting station C.

[0088] The rotary drive mechanism 3 drives the rotary plate 4 to rotate, causing the transport mechanism 5 to rotate from the placement station C towards the pick-up station A. During this process, the pitch changer 6 triggers the pitch changer assembly 54, causing the pitch changer assembly 54 to drive the first adsorption assembly 52 and the second adsorption assembly 53 to slide closer together. When the transport mechanism 5 rotates to the pick-up station A, the distance between the first adsorption assembly 52 and the second adsorption assembly 53 returns to the first distance. The above process is repeated, and the transport mechanism 5 performs the next round of placement operation.

[0089] As can be seen, in the battery cell mounting device of this application embodiment, during the process of rotating and transporting the two spacers picked up from the pick-up station A to the mounting station C, the variable pitch groove 6 and the variable pitch component 54 cooperate to adjust the distance between the first adsorption component 52 and the second adsorption component 53, so that the distance between the two adsorbed spacers 100 matches the distance between the two battery cells at the mounting station, and finally ensures that the first adsorption component 52 and the second adsorption component 53 can synchronously attach the two spacers 100 to the two battery cells located at the mounting station C, thereby improving the mounting effect.

[0090] Optionally, both the first adsorption component 52 and the second adsorption component 53 include a mounting plate 521 and a suction cup 522 mounted on the lower end of the mounting plate, wherein:

[0091] The mounting plate 521 of the first adsorption component 52 and the mounting plate 521 of the second adsorption component 53 are both connected to the fixed base 51. The suction cups 522 of the first adsorption component 52 and the suction cups 522 of the second adsorption component 53 can be horizontally slidably connected to the corresponding mounting plates 521. The suction cups 522 of the first adsorption component 52 and the suction cups 522 of the second adsorption component 53 are respectively used to adsorb a spacer 100.

[0092] The variable pitch assembly 54 includes a transmission part 541 and a follower wheel 542, wherein the follower wheel 542 is mounted on the top of the transmission part 541 and located in the variable pitch groove 6. The transmission part 541 is connected to the suction cup 522 of the first adsorption assembly 52 and the suction cup 522 of the second adsorption assembly 53 respectively.

[0093] When the transport mechanism 5 rotates from the pick-up station A toward the placement station C, the variable pitch groove 6 triggers the transmission part 541 via the follower wheel 542, thereby causing the transmission part 541 to drive the suction cup 522 of the first adsorption component 52 and the suction cup 522 of the second adsorption component 53 to slide apart to both sides.

[0094] When the transport mechanism 5 rotates from the placement station C toward the pick-up station A, the variable pitch groove 6 triggers the transmission part 541 via the follower wheel 542, causing the transmission part 541 to drive the suction cups 522 of the first adsorption component 52 and the suction cups 522 of the second adsorption component 53 to slide closer to the center.

[0095] As can be seen, since the follower wheel 542 installed at the top of the transmission unit 541 is located in the pitch groove 6, and the suction cups 522 of the first adsorption assembly 52 and the second adsorption assembly 53 are respectively connected to the transmission unit 541, when the transport mechanism 5 rotates and switches between the pick-up station A and the placement station C, the follower wheel 542 is confined in the pitch groove 6 and slides along the pitch groove 6.

[0096] Thus, by differentiating the pitch grooves located at the pick-up station A and the placement station C, it is possible to achieve the following: when the follower wheel 542 slides from the pitch groove at the pick-up station A toward the pitch groove at the placement station C, the distance between the follower wheel 542 and the rotation center of the rotating plate 4 changes. This triggers the transmission unit 541 to drive the suction cups 522 of the first adsorption assembly 52 and the second adsorption assembly 53 to slide apart to both sides. Similarly, when the follower wheel 542 slides from the pitch groove at the placement station C toward the pitch groove at the pick-up station A, the distance between the follower wheel 542 and the rotation center of the rotating plate 4 changes. This triggers the transmission unit 541 to drive the suction cups 522 of the first adsorption assembly 52 and the second adsorption assembly 53 to slide closer together to the center.

[0097] To provide sufficient installation space for the suction cups 522 of the first adsorption component 52 and the second adsorption component 53, and to ensure that the suction cups 522 of the first adsorption component 52 and the second adsorption component 53 can slide towards the center or slide apart horizontally, the mounting plates 521 of the first adsorption component 52 and the second adsorption component 53 can optionally be L-shaped plates. Taking the mounting plate 521 of the first adsorption component 52 as an example, the vertical part of the mounting plate 521 is connected to the side wall of the fixing base 51, and the suction cups 522 of the first adsorption component 52 are slidably connected to the lower surface of the horizontal part of the mounting plate 521, and can slide towards or away from the second adsorption component 54 relative to the horizontal part of the mounting plate 521.

[0098] like Figure 7 As shown, optionally, the variable pitch groove 6 includes a first arc-shaped segment 61 and a second arc-shaped segment 62, wherein the pick-up station A is located at the middle of the first arc-shaped segment 61, and the placement station C is located at the middle of the second arc-shaped segment 62. When the follower wheel 542 slides along the first arc-shaped segment 61, the distance between the follower wheel 542 and the rotation center of the rotating plate 4 remains at a first distance. As the follower wheel 542 slides from the first arc-shaped segment 61 to the second arc-shaped segment 62 and slides along the second arc-shaped segment 62 toward the placement station C, the distance between the follower wheel 542 and the rotation center of the rotating plate 4 gradually increases to a second distance. When the follower wheel 542 slides along the second arc-shaped segment 62 from the placement station C toward the first arc-shaped segment 61, the distance between the follower wheel 542 and the rotation center of the rotating plate 4 gradually decreases to the first distance.

[0099] like Figures 6 to 9 As shown, the transmission unit 541 includes a rotating shaft 543, a follower rod 544, a spring 545, a cam 546, a first pusher wheel 547, and a second pusher wheel 548, wherein:

[0100] The rotating shaft 543 is rotatably mounted on the fixed base 51 in the vertical direction. The first end of the follower rod 544 is fixedly connected to the upper end of the rotating shaft 543, and the follower wheel 542 is rotatably mounted on the second end of the follower rod 544.

[0101] Cam 546 is fixedly connected to the lower end of rotating shaft 543, first push roller 547 is installed on suction cup 522 of first adsorption assembly 52, and second push roller 548 is installed on suction cup 522 of second adsorption assembly 53.

[0102] The two ends of the spring 545 are respectively connected to the suction cup 522 of the first adsorption component 52 and the suction cup 522 of the second adsorption component 53. The spring 545 is used to pull the suction cup 522 of the first adsorption component 52 and the suction cup 522 of the second adsorption component 53 towards the middle, so that the first pusher 547 and the second pusher 548 elastically press against the two side walls of the cam 546.

[0103] With this configuration, when the follower wheel 542 slides from the first arc segment 61 into the second arc segment 62 and slides along the second arc segment 62 toward the patch placement station C, the distance between the follower wheel 542 and the center of the rotating plate 4 gradually increases from a smaller first distance to a larger second distance. The follower wheel 542 rotates under pressure, thereby driving the follower rod 544 to rotate. The follower rod 544 drives the cam 546 to rotate in a first clockwise direction (e.g., clockwise) via the rotating shaft 543. The cam 546 pushes the suction cups 522 of the first adsorption assembly 52 and the second adsorption assembly 53 to both sides, thereby causing the suction cups 522 of the first adsorption assembly 52 and the second adsorption assembly 53 to slide apart to both sides. At the same time, the spring 545 is stretched and deformed.

[0104] As the follower wheel 542 slides along the second arc segment 62 from the patch placement station C toward the first arc segment 61, the distance between the follower wheel 542 and the center of the rotating plate 4 gradually decreases from a larger second distance to a smaller second distance. The follower wheel 542 rotates under pressure, thereby driving the follower rod 544 to rotate. The follower rod 544 drives the cam 546 to rotate in the second clockwise direction (e.g., counterclockwise direction) via the rotating shaft 543. During this process, the spring 545 loses pressure and rebounds, thereby pulling the suction cups 522 of the first adsorption assembly 52 and the second adsorption assembly 53 towards the center, causing the suction cups 522 of the first adsorption assembly 52 and the second adsorption assembly 53 to slide closer together towards the center.

[0105] like Figure 7 As shown, optionally, the first arc segment 61 is a semicircular arc with a radius of a first distance, and the second arc segment 62 is a semielliptical arc with a major semi-axis of a second distance, whose two ends respectively connect with the two ends of the first arc segment 61. Optionally, the line L connecting the two connection points of the first arc segment 61 and the second arc segment 62 passes through the rotation center of the rotating plate 4, so that the centers of the first arc segment 61 and the second arc segment 62 coincide with the rotation center of the rotating plate 4. This configuration allows for smooth connection between the first arc segment 61 and the second arc segment 62, preventing the follower wheel 542 from getting stuck when entering the second arc segment 62 from the first arc segment 61 and from the second arc segment 62 back to the first arc segment 61.

[0106] like Figure 7As shown, optionally, convex arc surfaces 546a extending outward from the middle of the cam 546 are respectively provided on the two side walls of the cam 546. By providing convex arc surfaces 546a extending outward from the middle of the cam 546 on the two side walls of the cam 546, it can be achieved that when the cam 546 rotates a preset angle in the first clockwise direction (e.g., clockwise direction), the first pusher 547 and the second pusher 548 slide from the middle of the cam 546 to the corresponding side convex arc surfaces 546a and move along the convex arc surfaces 546a, thereby causing the first pusher 547 and the second pusher 548 to be pushed to both sides by the convex arc surfaces 546a on the two side walls of the cam 546, ultimately causing the suction cups 522 of the first adsorption component 52 and the suction cups 522 of the second adsorption component 53 to slide apart to both sides, and the spring 545 is stretched and deformed.

[0107] When the cam 546 rotates in the second clockwise direction (e.g., counterclockwise direction), the first pusher 547 and the second pusher 548 slide from the corresponding side convex arc surface 546a toward the middle of the cam 546 and return to their original positions. The distance between the first pusher 547 and the second pusher 548 decreases, and the spring 545 loses pressure and rebounds, thereby driving the suction cup 522 of the first adsorption component 52 and the suction cup 522 of the second adsorption component 53 to slide closer to the middle.

[0108] like Figure 6 As shown, optionally, the transmission part 541 also includes a mounting body 5410, which is fixedly connected to the fixed base 51. The rotating shaft 543 is rotatably inserted into the mounting body 5410 in the vertical direction, with the upper end of the rotating shaft 543 extending upward through the mounting body 5410 and the lower end of the rotating shaft 543 extending downward through the mounting body 5410.

[0109] By setting the mounting body 5410, the support limit of the rotating shaft 543 is realized, preventing the rotating shaft 543 and the cam 546 from tilting or deflecting, thereby ensuring the rotational stability of the cam 546.

[0110] Mounting body 5410 can be, for example, a mounting block with an internal rotating bearing, through which the rotating shaft 543 passes. Mounting body 5410 can also be a cylinder block or other structural components.

[0111] like Figure 3 As shown, optionally, the rotating plate 4 is rotatably connected to the top plate 2 via a plane bearing 7. The rotation drive mechanism 3 includes a rotation drive component 31 and a rotation shaft 32. The rotation drive component 31 is disposed on the upper side of the top plate 2, the upper end of the rotation shaft 32 is connected to the drive end of the rotation drive component 31, and the lower end of the rotation shaft 32 passes downward through the top plate 2 and the plane bearing 7 and is connected to the rotating plate 4. The rotation drive component 31 drives the rotating plate 4 to rotate relative to the top plate 2 via the rotation shaft 32. The rotation drive component 31 can be, for example, a servo motor.

[0112] The rotating plate 4 is rotatably connected to the top plate 2 via the plane bearing 7, which allows the rotating plate 4 to rotate freely relative to the top plate 2 and improves the connection stability between the rotating plate 4 and the top plate 5, so that the rotating plate 4 remains horizontal during rotation and avoids tilting or large-amplitude vibration during rotation.

[0113] When the transport mechanism 5 rotates to the wafer picking station A, there will be a height difference between the first adsorption component 52 and the second adsorption component 53 of the transport mechanism 5 and the spacer to be picked up. Similarly, when the transport mechanism 5 rotates to the wafer mounting station C, there will also be a height difference between the first adsorption component 52 and the second adsorption component 53 of the transport mechanism 5 and the cell to which the spacer is to be installed.

[0114] Therefore, optional, such as Figures 3 to 5 As shown, the mounting plate 521 of the first adsorption component 52 and the mounting plate 521 of the second adsorption component 53 can be slidably connected to the fixed base 51. For example, the fixed base 51 has slide rails extending vertically on its two opposite side walls, and the mounting plate 521 of the first adsorption component 52 and the mounting plate 521 of the second adsorption component 53 are slidably connected to the slide rail on one side wall of the fixed base 51 via sliders.

[0115] The cell mounting device in this embodiment of the application also includes two lifting drive mechanisms 8 disposed on the top plate 2, which are respectively disposed at the chip picking station A and the chip mounting station C.

[0116] When the transport mechanism 5 rotates to the pick-up station A or the placement station C, the mounting plate 521 of the first adsorption component 52 and the mounting plate 521 of the second adsorption component 53 respectively connect with the drive end of the lifting drive mechanism 8 at the corresponding position. The lifting drive mechanism 8 is configured to drive the first adsorption component 52 and / or the second adsorption component 53 to lift.

[0117] By setting up lifting drive mechanisms 8 at the wafer picking station A and the wafer placement station C respectively, when the transport mechanism 5 rotates to the wafer picking station A and connects with the drive end of the lifting drive mechanism 8 at the wafer picking station A, the lifting drive mechanism 8 at the wafer picking station A can drive the first adsorption component 52 and / or the second adsorption component 53 to rise and fall, thereby allowing the first adsorption component 52 and / or the second adsorption component 53 to pick up the spacer from the wafer picking station.

[0118] The lifting drive mechanism 8 at the tablet taking station A can selectively drive one of the first adsorption component 52 and the second adsorption component 53 to rise and fall, so that one of the first adsorption component 52 and the second adsorption component 53 can pick up the spacer from the tablet taking station. Alternatively, the first adsorption component 52 and the second adsorption component 53 can rise and fall synchronously, so that the first adsorption component 52 and the second adsorption component 53 can pick up one spacer from the tablet taking station simultaneously.

[0119] When the transport mechanism 5 rotates to the mounting station C and connects with the driving end of the lifting drive mechanism 8 at the mounting station C, the lifting drive mechanism 8 at the mounting station C can drive the first adsorption component 52 and / or the second adsorption component 53 to rise and fall, so that the first adsorption component 52 and / or the second adsorption component 53 will attach the adsorbed spacer to the corresponding battery cell.

[0120] The lifting drive mechanism 8 at the wafer picking station A can selectively drive one of the first adsorption component 52 and the second adsorption component 53 to lift or lower, so that one of the first adsorption component 52 and the second adsorption component 53 can attach the picked-up spacer to the battery cell. Alternatively, the first adsorption component 52 and the second adsorption component 53 can lift or lower synchronously, so that the first adsorption component 52 and the second adsorption component 53 can attach the picked-up spacer to the corresponding battery cell synchronously.

[0121] Furthermore, since the lifting drive mechanism 8 is fixedly mounted on the top plate 2, it can dock with and disengage from the conveying mechanism 5. Therefore, on the one hand, the lifting drive mechanism 8 does not need to rotate with the conveying mechanism 5, thereby reducing the driving load on the rotary drive mechanism 3. On the other hand, when multiple conveying mechanisms 5 are provided, the lifting drive mechanism 8 is reused, that is, the lifting drive mechanism 8 can realize the lifting drive of any conveying mechanism 5 currently rotating to the pick-up station A or the placement station C. Therefore, it is not necessary to set up a corresponding lifting drive mechanism for each conveying mechanism 5, thereby reducing the equipment complexity and cost of this application.

[0122] like Figures 3 to 5 As shown, optionally, the cell patching device in this embodiment further includes a limiting disk 9, which is located below the top plate 2. An annular guide channel is formed between the top plate 2 and the limiting disk 9. Both the top plate 2 and the limiting disk 9 are provided with clearance notches 10 at positions corresponding to the lifting drive mechanism 8. Optionally, the limiting disk 9 is horizontally connected to the bottom of the top plate 2 via several circumferentially arranged connecting rods.

[0123] The top of the mounting plate 521 of the first adsorption component 52 and the mounting plate 521 of the second adsorption component 53 are both provided with limiting wheels 523. The limiting wheels 523 are located in the guide channel and can slide along the guide channel.

[0124] The lifting drive mechanism 8 includes a first lifting drive part 81 and a second lifting drive part 82 arranged side by side. The movable parts of the first lifting drive part 81 and the second lifting drive part 82 are both located at the avoidance gap 10.

[0125] When the transport mechanism 5 rotates to the pick-up station A or the placement station C, the limiting wheel 523 of the first adsorption component 52 enters the movable part of the first lifting drive unit 81, and the limiting wheel 523 of the second adsorption component 53 enters the movable part of the second lifting drive unit 82. The first lifting drive unit 81 can drive the first adsorption component 52 to rise and fall, and the second lifting drive unit 53 can drive the second adsorption component 53 to rise and fall.

[0126] By setting a limiting plate 9 below the top plate 2, and by configuring the lifting drive mechanism 8 to include a first lifting drive part 81 and a second lifting drive part 82 capable of independent lifting drive, this embodiment of the application achieves that when the transport mechanism 5 rotates to the pick-up station A or the placement station C, the first adsorption component 52 and the second adsorption component 53 can respectively dock with the first lifting drive part 81 and the second lifting drive part 82 of the lifting drive mechanism 8 via corresponding limiting wheels 523. This allows the first lifting drive part 81 and the second lifting drive part 82 to independently lift and lower the first adsorption component 52 and the second adsorption component 53, thereby meeting the pick-up and placement requirements under different circumstances.

[0127] For example, when the conveying mechanism 5 rotates to the chip mounting station C, the first adsorption component 52 needs to mount the picked-up spacer (e.g., a qualified silicon wafer that has been inspected and confirmed) onto the corresponding cell, while the second adsorption component 53 cannot mount the picked-up spacer (e.g., a defective silicon wafer that has been inspected and confirmed) onto the corresponding cell. At this time, the first lifting drive unit 81 needs to perform lifting drive on the first adsorption component 52, while the second lifting drive unit 82 does not need to perform lifting drive on the second adsorption component 53.

[0128] Optionally, the first lifting drive unit 81 and the second lifting drive unit 82 have the same structure. Taking the first lifting drive unit 81 as an example, optionally, such as Figure 5 As shown, it includes a lifting drive component 811, a lifting seat 812, a limiting block 813, and a support plate 814. The lifting drive component 811 is disposed on the top plate 2, the lifting seat 812 is connected to the driving end of the lifting drive component 811, the limiting block 813 and the support plate 814 are disposed vertically on the lifting seat 812, and a docking channel is formed between the limiting block 813 and the support plate 814.

[0129] When the transport mechanism 5 rotates to the pick-up station A or the patching station C, the limiting wheel 523 of the first adsorption component 52 enters the docking channel of the first lifting drive unit 81, and the lifting drive component 811 of the first lifting drive unit 81 drives the lifting seat 812 to rise and fall, which in turn drives the first adsorption component 52 to rise and fall.

[0130] At the same time, the limiting wheel 523 of the second adsorption component 53 enters the docking channel of the second lifting drive unit 82, and the lifting drive component 811 of the second lifting drive unit 82 drives the lifting seat 812 to rise and fall, which in turn drives the second adsorption component 53 to rise and fall.

[0131] As can be seen, by configuring the first lifting drive unit 81 and the second lifting drive unit 82, the first lifting drive unit 81 and the second lifting drive unit 82 each have a docking channel composed of a limiting block 813 and a support plate 814. Thus, when the transport mechanism 5 rotates to the pick-up station A or the placement station C, the limiting wheels 523 corresponding to the first adsorption component 52 and the second adsorption component 53 can slide into the docking channels of the first lifting drive unit 81 and the second lifting drive unit 82 respectively, thereby achieving docking with the first lifting drive unit 81 and the second lifting drive unit 82. This allows the first lifting drive unit 81 and the second lifting drive unit 82 to independently lift and drive the first adsorption component 52 and the second adsorption component 53 respectively.

[0132] When the transport mechanism leaves the pick-up station A or the patch placement station C, the limiting wheels 523 corresponding to the first adsorption component 52 and the second adsorption component 53 slide out of the docking channels of the first lifting drive unit 81 and the second lifting drive unit 82, respectively, thereby achieving disengagement from the first lifting drive unit 81 and the second lifting drive unit 82.

[0133] The lifting drive component 811 can be any existing linear drive component capable of driving the lifting seat 812 to rise and fall, such as a cylinder, a lead screw motor, etc.

[0134] like Figure 1 and Figure 7 As shown, optionally, a detection station B is also provided on the rotation path of the conveying mechanism 5, and the chip picking station A, the detection station B and the chip placement station C are arranged sequentially along the rotation path of the conveying mechanism 5.

[0135] When the transport mechanism 5 rotates to the wafer picking station A, the transport mechanism 5 is configured to pick up two wafers from the wafer picking station A. For example, when the transport mechanism 5 includes a first adsorption component 52 and a second adsorption component 53, the first adsorption component 52 and the second adsorption component 53 respectively pick up one wafer from the wafer picking station A.

[0136] When the transport mechanism 5 rotates to the inspection station B, the inspection device located at the inspection station B positions the partition on the transport mechanism 5, thereby obtaining the position information of the two partitions.

[0137] When the transport mechanism 5 rotates to the chip mounting station C, the transport mechanism 5 is configured to attach the spacer to the battery cell located at the chip mounting station according to the spacer's position information.

[0138] By setting up a detection station B on the rotation path of the conveying mechanism 5 and setting up a detection device at the detection station B, the spacer can be positioned before the chip is applied. This allows the conveying mechanism 5 to apply the spacer to the battery cell located at the chip application station according to the spacer's position information, ensuring the chip application accuracy.

[0139] Optionally, the detection device is a vision device installed at detection station B. The vision device performs spectral positioning on the spacer on the transport mechanism 5 to obtain the position information of the spacer on the transport mechanism 5. The vision device provides the position information of the spacer to the control terminal of the transport mechanism 5, and the control terminal of the transport mechanism 5 can then attach the spacer to the battery cell located at the bonding station according to the position information of the spacer.

[0140] Optionally, the cell mounting device in this embodiment of the application is provided with at least three transport mechanisms 5. When the first transport mechanism 5 is at the chip picking station A, the second transport mechanism 5 is at the inspection station B, and the third transport mechanism 5 is at the mounting station C. The rotary drive mechanism 3 drives the rotary plate 4 to rotate, causing the first transport mechanism 5 to rotate from the chip picking station A to the inspection station B. The other transport mechanisms 5 then rotate sequentially to the next station. For example, the second transport mechanism 5 rotates from the inspection station B to the mounting station C, and the third transport mechanism 5 rotates from the mounting station C to the next station.

[0141] With this configuration, after the rotary drive mechanism 3 drives the rotary plate 4 to complete one rotation, each of the chip picking station A, the inspection station B, and the chip placement station C has a conveying mechanism 5. In this way, the three conveying mechanisms 5 can simultaneously perform chip picking, inspection, and chip placement actions at their respective stations, thereby speeding up the work cycle and improving the chip placement efficiency of the chip placement device of this application embodiment.

[0142] Optionally, the testing device installed at testing station B can not only detect and position the spacers on the conveying mechanism 5 to obtain their position information, but also perform quality inspection on the spacers to determine whether they are qualified. Of course, only qualified spacers confirmed by the testing device can be mounted onto the battery cells at the mounting station C.

[0143] Optionally, the cell mounting device in this embodiment is provided with four conveying mechanisms 5. An NG wafer unloading station D is also provided on the rotation path of the conveying mechanism 5, located between the mounting station C and the wafer picking station A. When the conveying mechanism 5 rotates to the inspection station B, the inspection device located at the inspection station B performs positioning and quality inspection on the spacers on the conveying mechanism 5, thereby obtaining the position information of the two spacers and confirming whether the two spacers are qualified spacers that meet the quality requirements.

[0144] When the transport mechanism 5 rotates to the bonding station C, it bonds the qualified spacers to the corresponding cells at station C based on their location information. Unqualified spacers, as determined by inspection, remain on the transport mechanism 5. When the transport mechanism 5 rotates to the NG wafer unloading station, it is configured to place the unqualified spacers at the NG wafer unloading station D, for example, into the spacer recycling box located at station D.

[0145] For example, in one embodiment, when the transport mechanism 5 rotates to the inspection station B, the inspection device at inspection station B performs positioning and quality inspection on the two spacers of the first adsorption component 52 and the second adsorption component 53, confirming that the spacer on the first adsorption component 52 is a qualified spacer and the spacer on the second adsorption component 53 is a defective spacer. When the transport mechanism 5 rotates to the bonding station C, the first adsorption component 52 descends and bonds its spacers to the battery cell, while the second adsorption component 53 remains stationary and does not bond spacers. When the transport mechanism 5 rotates to the NG wafer unloading station, the second adsorption component 53 places the defective spacers it holds into the spacer recycling box at the NG wafer unloading station D.

[0146] It can be seen that by setting the detection device to perform quality inspection of the separators, and setting an NG sheet unloading station D between the sheet mounting station C and the sheet picking station A, the unloading of unqualified separators is realized automatically, and it is ensured that only qualified separators that have been inspected and confirmed are mounted onto the battery cells.

[0147] Optionally, when the first transport mechanism 5 is at the wafer pick-up station A, the second transport mechanism 5 is at the inspection station B, the third transport mechanism 5 is at the placement station C, and the fourth transport mechanism 5 is at the NG wafer unloading station D. With this configuration, after each rotation of the rotary drive mechanism 3 driving the rotary plate 4, a transport mechanism 5 is present at each of the wafer pick-up station A, inspection station B, and placement station C, thereby accelerating the work cycle and improving the battery cell placement efficiency of the battery cell placement device in this embodiment.
