Description

Technical Field

[0001] This utility model belongs to the field of battery cell manufacturing technology, and in particular relates to a battery cell patch assembly. Background Technology

[0002] In the battery cell manufacturing process, the application of MPPs (protective film / sheet / component) is one of the key steps, and its quality directly affects the performance and safety of the battery cell. Currently, the mainstream methods are still manual application or semi-automatic tooling assistance. The former is inefficient, has poor consistency, and is prone to problems such as misalignment and air bubbles; while the latter has preliminary positioning capabilities, manual intervention is still required in the picking, placing, and precision application stages, so quality and efficiency bottlenecks still exist.

[0003] To replace manual labor, the industry has introduced automated placement equipment. However, existing equipment relies on complex and space-consuming positioning systems to achieve precise alignment. Such designs not only result in high equipment costs and complex maintenance, but also make it difficult to integrate into compact production lines, thus limiting production cycle time. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model discloses a cell patch assembly that ensures high precision and efficiency in the attachment of protective components, while also featuring a compact structure and ease of integration, effectively reducing equipment costs and floor space.

[0005] The specific technical solution of this utility model is as follows: A cell patch assembly for attaching protective components to a cell, comprising: The film winding mechanism is used to output protective components; A conveying mechanism that drives the movement of the battery cell to deliver the battery cell into or out of the surface mount station; The adsorption mechanism is provided with a suction nozzle component for adsorbing the protective component and attaching the protective component to the battery cell located at the surface mount station. It also includes a positioning mechanism, which is set at the chip mounting station. The positioning mechanism includes a clamping group, which includes a clamping member one and a clamping member two. Both clamping member one and clamping member two have right-angle structures. The movement direction of clamping member one and clamping member two is inclined to the movement direction of the battery cell. Clamping member one and clamping member two move relative to each other to clamp the diagonal of the battery cell at the chip mounting station.

[0006] This application uses a clamping component with a right-angle structure that is tilted towards the battery cell to clamp the battery cell diagonally. This allows for simultaneous correction of the battery cell's position and angle from two vertical directions, enabling rapid and accurate positioning of the battery cell at the chip mounting station, which is beneficial for subsequent chip mounting operations. At the same time, this tilted layout significantly reduces the space occupied by the clamping assembly in the direction perpendicular to the battery cell's movement, thereby effectively shortening the overall length of the structure in the aforementioned vertical direction and resulting in a more compact structure in this direction.

[0007] Preferably, the positioning mechanism has multiple clamping groups evenly arranged in the direction of movement of the battery cell.

[0008] This structure enables the surface mount assembly to perform surface mount operations on multiple cells at once, effectively improving process efficiency.

[0009] Preferably, the conveying mechanism includes a double-speed chain component, a tooling plate, and profiles for assembling the double-speed chain component; The tooling plate is used to mount the battery cell, the speed-multiplying chain component is used to drive the tooling plate, the profile is provided with a guard strip along the movement path of the battery cell, and the tooling plate has a guide wheel that slides with the guard strip.

[0010] This structure is simple and has high transmission efficiency, which can effectively achieve stable and efficient transmission of battery cells. The protective strips on the profile and the guide wheels on the tooling plate work together to guide the movement of the tooling plate, thereby effectively ensuring the straightness and stability of the battery cells on the transmission path.

[0011] Preferably, the tooling plate is provided with a positioning block, and the battery cell is placed in the positioning block.

[0012] Setting positioning blocks on the tooling plate provides an initial placement position for the battery cells. This not only simplifies the feeding operation but also restricts the movement of the battery cells in the early stages of conveying, which helps improve the positioning action of the subsequent positioning mechanism and thus better ensures positioning accuracy.

[0013] Preferably, it also includes a lifting mechanism, which is disposed at the patch placement station; The lifting mechanism includes a lifting rod, and the tooling plate is provided with a positioning part. When the tooling plate moves to the patching station, the lifting rod and the positioning part cooperate to lift the tooling plate away from the double-speed chain component.

[0014] The lifting mechanism works in conjunction with the positioning part on the tooling plate to lift the tooling plate at the bonding station, thereby disengaging the tooling plate from the double-speed chain component. This eliminates the displacement error of the tooling plate during the bonding process, thus providing a stable and interference-free working environment for the bonding action.

[0015] Preferably, the film winding mechanism includes a raw material roll, an upper roll, and a lower roll. The raw material roll is wound with an attachment. The attachment includes a protective layer, a protective element, and a carrier layer from top to bottom. The upper roll is used to wind up the protective layer, and the carrier layer is used to wind up the carrier layer. The film winding mechanism also includes a linearly movable support plate for receiving the adhesive attachments for peeling off the protective layer; The suction nozzle component adsorbs and peels off the protective component at the support plate; The carrier layer rotates to the lower roller at the end of the bearing plate.

[0016] The film winding mechanism achieves continuous and smooth peeling and output of the protective parts by winding the upper protective layer with the upper roller and the carrier layer with the lower roller, and by using the carrier plate to receive the peeled attachments. This avoids manual intervention and effectively improves the material supply efficiency and reliability.

[0017] Preferably, the end of the bearing plate has a bevel.

[0018] The beveled design at the end of the bearing plate allows the carrier layer to bend and rotate smoothly, reducing the peeling resistance and stress concentration of the carrier layer, while preventing the protective component from shifting during the peeling process.

[0019] Preferably, the adsorption mechanism further includes a triaxial carrier for driving the suction nozzle component to move in the X, Y, and Z axis directions.

[0020] The triaxial carrier provides the suction nozzle component with the ability to move in three-dimensional space, enabling the suction nozzle component to complete the actions of picking up material from the carrier plate, moving it above the battery cell, and finally bonding it. The structure is simple and easy to set up.

[0021] Preferably, the suction nozzle component includes a first sub-component and a second sub-component, and both the first sub-component and the second sub-component are provided with suction nozzles; The suction nozzle component also includes a rail base and a screw. The rail base is connected to a three-axis carrier, and the screw is mounted on the rail base and has a motor for driving its rotation. The screw is provided with a first thread and a second thread; The first sub-component is threadedly connected to the first threaded connection and slidably connected to the rail base; the second sub-component is threadedly connected to the second threaded connection and slidably connected to the rail base.

[0022] The sub-component one and sub-component two can move towards or away from each other synchronously to adjust the spacing of multiple suction nozzles according to the size of the battery cell, thereby adapting to different working conditions.

[0023] Preferably, it also includes a shooting mechanism, which is located on the side of the output protective component of the film winding mechanism, and is used to collect the position information of the protective component and / or the attachment position information of the battery cell.

[0024] The imaging mechanism uses machine vision to identify the real-time position of the protective components and the battery cells. It can then use the feedback data to locate the working position of the adsorption mechanism, thereby compensating for positional errors and ensuring better adsorption and attachment accuracy, thus improving the attachment quality.

[0025] Compared with the prior art, this utility model effectively achieves rapid positioning of the battery cell through an inclined diagonal clamping and positioning mechanism. The inclined layout of the clamping components effectively compresses the vertical dimension of the battery cell in the direction of movement, making the overall structure more compact and thus facilitating the miniaturization of the overall structure. This application achieves patching through a mechanical structure, which effectively improves process efficiency and avoids the defects of low precision and low efficiency caused by manual operation.

Detailed Implementation

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0029] like Figures 1 to 8 As shown, a battery cell patch assembly is used to attach a protective component 200 to a battery cell 100. It includes a film winding mechanism 300, a conveying mechanism 400, and an adsorption mechanism 500. The film winding mechanism 300 outputs the protective component 200. The conveying mechanism 400 drives the battery cell 100 to move, feeding the battery cell 100 into or out of the patch assembly station. The adsorption mechanism 500 is equipped with a suction nozzle 1 for adsorbing the protective component 200 and attaching it to the designated position. The battery cell 100 is mounted at the surface mount station; it also includes a positioning mechanism, which is disposed at the surface mount station. The positioning mechanism includes a clamping group, which includes a clamping member 2 and a clamping member 3. Both the clamping member 2 and the clamping member 3 have right-angle structures. The movement direction of the clamping member 2 and the clamping member 3 is inclined to the movement direction of the battery cell 100. The clamping member 2 and the clamping member 3 move relative to each other to clamp the diagonal of the battery cell 100 at the surface mount station.

[0030] This embodiment overcomes the shortcomings of existing cell 100 bonding processes, such as poor precision, low efficiency, and poor versatility. It achieves automatic feeding, precise alignment, efficient bonding of the protective component 200, and automatic transfer of the cell 100. Furthermore, it is compatible with bonding requirements for protective components 200 of different sizes to the cell 100. Specifically, the film winding mechanism 300 transports the protective component 200 to a preset placement position, allowing the adsorption mechanism 500 to adsorb the protective component 200 at that position. When the cell 100 is transferred to the bonding station by the conveying mechanism 400, the positioning mechanism limits the cell 100, thereby ensuring that the adsorption mechanism 500 adsorbs the protective component 200 onto the cell 100. After bonding, the conveying mechanism 400 transfers the cell 100 out of the bonding assembly. Therefore, this embodiment achieves a fully automated bonding process with excellent positioning accuracy for the cell 100, ensuring bonding precision. In this embodiment, two sets of film winding mechanisms 300 and two sets of adsorption mechanisms 500 are provided to improve the overall process efficiency.

[0031] Furthermore, the positioning mechanism has multiple sets of clamping groups evenly arranged in the direction of movement of the battery cell 100. This embodiment can realize the patching of multiple battery cells 100, and is simple in structure, practical and efficient.

[0032] The battery cell 100 is typically rectangular with four right angles. The structures of clamping member 2 and clamping member 3 match the corner structures of the battery cell 100. Since they also have a driving direction inclined to the direction of movement of the battery cell 100, clamping member 2 and clamping member 3 can clamp and position the battery cell 100 in the X-axis and Y-axis directions. This effectively avoids the need for more than two clamping members to limit and position the battery cell 100. In other words, the inclined clamping assembly also significantly reduces design and manufacturing costs. In this embodiment, clamping member 2 and clamping member 3 are pushed and pulled by a cylinder.

[0033] like Figures 2-4As shown, in this embodiment, the conveying mechanism 400 includes a double-speed chain component 4, a tooling plate 5, and a profile 6 for assembling the double-speed chain component 4. The tooling plate 5 is used to mount the battery cell 100, and the double-speed chain component 4 is used to drive the tooling plate 5. The profile 6 is provided with a guard strip 7 along the movement path of the battery cell 100, and the tooling plate 5 has a guide wheel 8 that slides with the guard strip 7. This structure can well meet the driving requirements of the tooling plate 5, thereby enabling the battery cell 100 to be well transported into or out of the mounting station. In this embodiment, the guard strip 7 can be fixedly connected to the profile 6 or detachably connected, resulting in a simple structure. Furthermore, the tooling plate 5 is provided with a positioning block, and the battery cell 100 is placed in the positioning block. Specifically, the positioning block includes corner block 9, corner block 10, and side block 11. The three of them achieve preliminary positioning of the battery cell 100 in the X-axis and Y-axis directions. The structure is simple. The corner block 9, corner block 10, and side block 11 can be adjusted in distance and size according to the actual situation.

[0034] like Figure 3 As shown, in order to better maintain the positional stability of the tooling plate 5 during the placement process, a lifting mechanism is also included. The lifting mechanism is set at the placement station. The lifting mechanism includes a lifting rod 12, and the tooling plate 5 is provided with a positioning part 13. When the tooling plate 5 moves to the placement station, the lifting rod 12 and the positioning part 13 cooperate to lift the tooling plate 5 away from the double-speed chain component 4. In one embodiment, the free end of the lifting rod 12 is provided with a disc-shaped portion 14, which extends a predetermined length beyond the disc-shaped portion 14. The positioning portion 13 is configured as a positioning hole. When the free end of the lifting rod 12 extends into the positioning hole, its disc-shaped portion 14 fits against the bottom surface of the tooling plate 5. Therefore, as the lifting rod 12 further extends, it can lift the tooling plate 5. In another embodiment, the positioning portion 13 can also be a positioning groove. The disc-shaped portion 14 serves as the end of the lifting rod 12, so the direct cooperation between the disc-shaped portion 14 and the positioning groove can also meet the lifting requirement of the tooling plate 5. This structure is simple and easy to operate. It can be seen that the lifting mechanism can disengage the tooling plate 5 from the speed-multiplying chain member 4, thus maintaining the relative stillness of the tooling plate 5 during the chip mounting process, thereby ensuring the positional stability of the battery cell 100 and further improving the chip mounting accuracy.

[0035] like Figure 5 and Figure 6As shown, in this embodiment, the film winding mechanism 300 includes a raw material roll 15, an upper roll 16, and a lower roll 17. The raw material roll 15 is wound with an attachment 600. The attachment 600 includes a protective layer 700, a protective element 200, and a carrier layer 800 from top to bottom. The upper roll 16 is used to wind up the protective layer 700, and the carrier layer 800 is used to wind up the carrier layer 800. The film winding mechanism 300 also includes a linearly displaceable support plate 18 for receiving the attachment 600 that peels off the protective layer 700. The suction nozzle component 1 adsorbs the protective element 200 at the support plate 18. The carrier layer 800 rotates to the lower roll 17 at the end of the support plate 18. In the initial stage, the attachment 600 has a separation feature, that is, the protective layer 700, the protective element 200 and the carrier layer 800 can be separated from each other. The attachment 600 is wound on the raw material roll 15, and the separated protective layer 700 is wound on the upper roll 16 to realize the recycling of the protective layer 700. The carrier layer 800 carrying the protective element 200 transitions to the support plate 18, so that the adsorption mechanism 500 adsorbs the protective layer 700 on the upper surface of the support plate 18, while the carrier layer 800 rotates to the lower roll 17 at the end of the support plate 18, thereby realizing the recycling of the carrier layer 800. In practical use, after the protective layer 700 is separated, the carrier layer 800 carries the protective element 200 forward to the end surface of the support plate 18. Then, the adsorption mechanism 500 adsorbs the protective element 200, while the support plate 18 retracts, thus separating the protective element 200 from the support plate 18. The support plate 18 then moves forward again, placing the next protective element 200 on the end surface of the support plate 18. By repeating the above process, the adsorption mechanism 500 can continuously pick up the protective element 200. It should be noted that the above process requires coordinated movement between the film winding mechanism 300 and the support plate 18 to meet specific usage requirements.

[0036] In this embodiment, the support plate 18 achieves linear displacement via a lead screw mechanism 19. To provide smooth movement of the carrier layer 800, the end of the support plate 18 has an inclined surface 20.

[0037] like Figure 1 and Figure 7 , Figure 8As shown, in this embodiment, the adsorption mechanism 500 further includes a triaxial carrier for driving the suction nozzle component 1 to move in the X, Y, and Z axis directions. Specifically, the triaxial carrier includes an X-axis carrier 21, a Y-axis carrier 22, and a Z-axis carrier 23. The fixed end of the Y-axis carrier 22 is connected to the movable end of the X-axis carrier 21, the fixed end of the Z-axis carrier 23 is connected to the movable end of the Y-axis carrier 22, and the suction nozzle component 1 is connected to the movable end of the Z-axis carrier 23. Furthermore, the suction nozzle component 1 includes a first sub-component 24 and a second sub-component 25, both of which are equipped with suction nozzles. The suction nozzle component 1 also includes a rail base 26 and a screw 27. The rail base 26 is connected to a three-axis carrier, and the screw 27 is mounted on the rail base 26 and has a motor for driving its rotation. The screw 27 has a first thread and a second thread. The first sub-component 24 is connected to the first thread and slidably connected to the rail base 26. The second sub-component 25 is connected to the second thread and slidably connected to the rail base 26. The rail base 26 is connected to the movable end of the Z-axis carrier 23. When the screw 27 rotates, a stable relative movement can be generated between the first sub-component 24 and the second sub-component 25, realizing distance adjustment between them, thereby adapting to the size of the battery cell 100.

[0038] like Figure 9 As shown, this embodiment also includes an imaging mechanism 900, which is located on one side of the output position of the protective component 200 of the film winding mechanism 300. The imaging mechanism 900 is used to collect the position information of the protective component 200 and / or the attachment position information of the battery cell 100. The imaging mechanism 900 includes a CCD camera 28, a lens 29, and an aperture 30. The lens 29 is a wide-field-of-view lens, and the aperture 30 is a large-size surface light source. The aperture 30 provides uniform and sufficient illumination, eliminating the interference of ambient light on imaging. The lens 29 can cover the imaging range of protective components 200 of different sizes without frequent adjustment of its parameters. The CCD camera 28 collects the position information of the protective component 200 on the carrier plate 18 and the position information of the battery cell 100 on the tooling plate 5, transmits the data to the control system, calculates the attachment deviation, and feeds it back to the adsorption mechanism 500, thereby achieving precise alignment. Therefore, after the film winding mechanism 300 conveys the protective component 200 to the carrier plate 18, the shooting mechanism 900 collects position data and calculates the deviation. The adsorption mechanism 500 adjusts its posture according to the deviation and picks up the protective component 200 from the carrier plate 18. At the same time, the conveying mechanism 400 and the positioning mechanism complete the positioning of the battery cell 100. Finally, the adsorption mechanism 500 accurately attaches the protective component 200 to the surface of the battery cell 100. After the attachment is completed, the battery cell 100 flows out with the tooling plate 5 through the conveying mechanism 400.

[0039] Specifically, the workflow of this embodiment can be implemented through the following process.

[0040] First, the system is initialized. Based on the specifications of the protective component 200 and the battery cell 100 to be attached, the feeding speed and limit parameters of the film rolling mechanism 300 are preset, the position of the suction nozzle component 1 and the placement position of the battery cell 100 on the tooling plate 5 are adjusted, and the imaging parameters and alignment accuracy threshold of the shooting mechanism 900 are configured.

[0041] Then, the battery cell 100 is transferred and positioned. The battery cell 100 is placed on the tooling plate 5 and transported to the attachment station by the double-speed chain component 4. Then, the lifting mechanism is activated to lift the tooling plate 5 away from the conveyor line. At the same time, the clamping group of the positioning mechanism clamps the battery cell 100 from the diagonal direction to complete the high-precision positioning. The relevant data is fed back to the control system in real time.

[0042] Then, the protective component 200 is fed and visually aligned. The film winding mechanism 300 operates, continuously outputting the attachment 600. The upper roll 16 and the lower roll 17 respectively wind up the protective layer 700 and the carrier layer 800, so that the protective component 200 is flat and exposed in the designated area of ​​the carrier plate 18. Then, the imaging mechanism 900 is started, and the CCD camera 28 acquires the image of the attachment position of the protective component 200 and the battery cell 100 under the assistance of a uniform light source, calculates the positional deviation, and sends it to the adsorption mechanism 500.

[0043] Then, the protective component 200 is picked up and attached. The adsorption mechanism 500 dynamically calibrates the three-axis coordinates according to the alignment data. The suction nozzle component 1 picks up the protective component 200 under negative pressure. Then, driven by the three-axis carrier, the protective component 200 is accurately transferred to the attachment area of ​​the battery cell 100. After being stably attached to the surface, the negative pressure is released to complete the attachment.

[0044] Finally, after a single attachment is completed, the clamping group is released, the lifting mechanism descends and resets, and the double-speed chain component 4 sends the attached battery cell 100 out of the station and simultaneously sends in the next group of battery cells 100 to be attached. The system repeats the above process to achieve continuous automated production.

[0045] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
