Description

Technical Field

[0001] This utility model relates to the field of soft-pack battery technology, and in particular to an adjustable packaging tray positioning structure and a cell packaging system containing the same. Background Technology

[0002] In the assembly process of pouch batteries, the encapsulation step involves first placing the perforated aluminum-plastic film into the encapsulation tray, then placing the welded battery cells into the tray, followed by tray positioning, cell positioning, top sealing, side sealing, and CCD (Continuous Discharge) processes. The dimensions and depth of the encapsulation tray cavity are among the key control items, requiring them to match the specifications of the welded battery cells. Currently, the workshop frequently switches between battery models (changing cell size and thickness), and with the introduction of new models, the production line needs to frequently switch encapsulation trays.

[0003] This method increases the time for equipment personnel to change packaging trays. In addition, the size of new battery cell models changes, requiring the customization of packaging trays with corresponding cavity structures. The positioning of multiple packaging trays also becomes a problem. If only external positioning fixtures are used, the repetition is high, the horizontal position of the tray cannot be guaranteed, and subsequent packaging processes are prone to problems such as trays not closing properly, misalignment of aluminum-plastic film, and folding of aluminum-plastic film at the bottom corners.

[0004] To address these issues, we propose an adjustable packaging tray positioning structure and a cell packaging system containing it. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes an adjustable packaging tray positioning structure and a cell packaging system containing the same, which can be adapted to the positioning requirements of various packaging trays to facilitate subsequent cell packaging operations.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: an adjustable packaging tray positioning structure, including: a horizontally distributed mounting track and a bidirectional adjustment component and a spacing adjustment component mounted on the mounting track. The bidirectional adjustment component includes two components and is arranged opposite to each other at both ends of the mounting track. Each bidirectional adjustment component includes a first driving member, a connecting plate, a sliding plate, a guide post, and a support corner seat. The guide post is fixed to both ends of the connecting plate. The sliding plate includes two components and is slidably connected opposite to both ends of the guide post. The support corner seat includes two components and is respectively fixed to the top of the sliding plate. The first driving member is fixed to the connecting plate and is used to drive the two sliding plates to slide relative to each other along the axial direction of the guide post. The spacing adjustment component includes a second driving member, which is used to servo drive one of the bidirectional adjustment components to move along the mounting track. The support corner seats in the two bidirectional adjustment components are located on the same plane and are distributed at four corners.

[0007] Furthermore, the first driving component consists of two servo cylinders, which are fixed opposite to each other at both ends of the connecting plate, with the output end of each servo cylinder correspondingly connected and fixed to each sliding plate.

[0008] Furthermore, the slide plate is a T-shaped plate, with its convex side bolted to the output end of the servo cylinder. The guide rails include two rails arranged vertically, and the slide plate is slidably connected to the two guide rails through a bearing seat.

[0009] Furthermore, a limiting plate is coaxially fixed to the intermediate shaft end of the guide rail, and a limiting pin is externally fixed to the limiting plate on the surface corresponding to each slide plate.

[0010] Furthermore, the exposed shaft section of the limiting pin has a length of 15-25mm.

[0011] Furthermore, the second driving component includes a servo motor, a transmission sprocket, a lead screw, a limit rod, a horizontal plate, and a vertical plate. The vertical plate includes two plates that are mounted and fixed opposite each other on the mounting rail via the horizontal plate. The two ends of the lead screw are rotatably connected to the vertical plate, and the two ends of the limit rod are fixed to the vertical plate. The servo motor is fixed to the outside of the vertical plate via a fixing bracket. One end of the transmission sprocket is connected to the output end of the servo motor for transmission, and the other end is connected to the lead screw for transmission.

[0013] Furthermore, the supporting corner bracket includes a base plate and a surrounding plate. The base plate has a triangular structure and is horizontally arranged. The surrounding plate is bent at 90° and vertically fixed to the inner side of the base plate. Multiple positioning holes are fixed on the surrounding plate to position the external pallet.

[0014] Furthermore, a baffle is fixed at the top of the bend in the enclosure, and the baffle is arranged parallel to the bottom plate.

[0015] A battery cell packaging system includes the adjustable packaging tray positioning structure described above.

[0016] Compared with the prior art, the beneficial effects of this utility model include: This solution, through the design of an adjustable packaging tray positioning structure, on the one hand, allows for quick changeover and improved production efficiency by adjusting the distance between the four support corner seats according to the tray size during production line changeover (packaging tray); on the other hand, the fixed-point support corner seats ensure the consistency of subsequent tray levelness, effectively preventing abnormal phenomena such as tray not closing properly, aluminum-plastic film misalignment, bottom corner aluminum-plastic film folding, poor aluminum-plastic film adsorption, and vacuum alarm.

[0024] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0025] According to one embodiment of the present invention, in conjunction with Figures 1-5 As shown.

[0026] In this embodiment, an adjustable packaging tray positioning structure includes: a horizontally distributed mounting track 1 and a bidirectional adjustment component 2 and a spacing adjustment component 3 mounted on the mounting track 1. The bidirectional adjustment component 2 comprises two components arranged opposite to each other at both ends of the mounting track 1. Each bidirectional adjustment component 2 includes a first drive element 4, a connecting plate 5, a sliding plate 6, a guide post 7, and a support corner seat 8. The guide post 7 is fixed to both ends of the connecting plate 5. The sliding plate 6 comprises two components slidably connected opposite to both ends of the guide post 7. The support corner seat 8 comprises two components and is respectively fixed to the top of the sliding plate 6. The first drive element 4 is fixed to the connecting plate 5 and is used to drive the two sliding plates 6 to slide relative to each other axially around the guide post 7. The spacing adjustment component 3 includes a second drive element 9, which is used to servo-drive one of the bidirectional adjustment components 2 to move along the mounting track 1. The support corner seats 8 in the two bidirectional adjustment components 2 are located on the same plane and are distributed at four corners.

[0027] Based on the above structural description, this application enables bidirectional spacing adjustment of the four support corner seats 8 through the bidirectional adjustment component 2 and the spacing adjustment component 3, so as to match the pallet structure of different sizes and specifications, and to keep the positioning horizontal plane of the four support corner seats 8 consistent at the same time. This avoids the problem of repeated disassembly and assembly required by the existing conventional tooling positioning method. The guarantee of horizontality also effectively prevents abnormal phenomena such as pallet not closing properly, aluminum-plastic film misalignment, aluminum-plastic film folding at the bottom corners, poor aluminum-plastic film adsorption, and vacuum alarm.

[0028] Specifically, for the driving implementation of the two components, the first driving component 4 consists of two servo cylinders 10, which are fixed opposite to each other at both ends of the connecting plate 5. The output end of each servo cylinder 10 is connected and fixed to each slide plate 6. The slide plate 6 is a T-shaped plate, with its convex side bolted to the output end of the servo cylinder 10. The guide rail includes two rails arranged vertically, and the slide plate 6 is slidably connected to the two guide rails through bearing seats. A limit plate 11 is also coaxially fixed to the middle shaft end of the guide rail, and a limit pin 12 is exposed on the surface of the limit plate 11 corresponding to each slide plate 6. The exposed shaft section length of the limit pin 12 is 15-25mm.

[0029] After the servo cylinder 10 outputs, it can drive the slide plate 6 to slide on the guide rail. The relative design can meet the spacing adjustment in the width direction of the tray, and the synchronous matching limit pin 12 controls the minimum spacing position.

[0030] The second driving component 9 includes a servo motor 13, a transmission sprocket 14, a lead screw 15, a limiting rod 16, a horizontal plate 17, and a vertical plate 18. Two vertical plates 18 are mounted opposite each other on a mounting rail via the horizontal plate 17. Both ends of the lead screw 15 are rotatably connected to the vertical plates 18. Both ends of the limiting rod 16 are fixed to the vertical plates 18. The servo motor 13 is fixed to the outside of the vertical plates 18 via a mounting bracket. One end of the transmission sprocket 14 is connected to the output end of the servo motor 13 for transmission, and the other end is connected to the lead screw 15 for transmission. A moving block 19 is fixed to the bottom of the connecting plate 5 in the bidirectional adjustment assembly 2 corresponding to the second driving component 9. The center of the moving block 19 is threadedly engaged with the lead screw 15, and both ends are slidably connected to the limiting rod 16.

[0031] After the servo motor 13 outputs, it can drive the lead screw 15 to rotate and position on the vertical plate 18. Then, the moving block 19, which is limited by the limit rod 16, can move linearly along its axis under the action of the thread of the lead screw 15. With the help of the bidirectional adjustment component 2 of another positioning position, the length and spacing of the tray can be adjusted. The adjustment process can be programmed by PLC, with a high degree of automation and no need for human intervention.

[0032] Similarly, the supporting corner bracket 8 includes a base plate 20 and a surrounding plate 21. The base plate 20 has a triangular structure and is horizontally arranged. The surrounding plate 21 is bent at 90° and vertically fixed to the inner side of the base plate 20. Multiple positioning holes 24 are fixed on the surrounding plate 21 to position the external pallet. A baffle 22 is fixed to the top of the bent portion of the surrounding plate 21, and the baffle 22 is arranged parallel to the base plate 20. The supporting corner bracket 8 has a simple structure, ensuring consistent horizontality while also providing pre-installed positioning for the top of the pallet, making it convenient and reliable.

[0033] Similarly, the battery cell packaging system that includes the adjustable packaging tray positioning structure described above is also within the protection scope of this utility model. For the remaining implementation components in the battery cell packaging system, refer to the existing structures in the field, which will not be elaborated here.

[0034] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
