Description

Technical Field: The present invention relates to a core pasting device and its working method. Background Art: In the new energy battery, a core pasting process is required to paste adhesive strips on the battery surface. Due to the large number of new energy batteries, manual pasting has low efficiency and heavy workload.

[0003] Currently, the Chinese patent "A Core Pasting Device CN113745634A" is retrieved, which includes a workbench group, a core transplanting component, a glue feeding and cutting component, a pasting component, and a rolling component. The workbench group includes a feeding platform, a pasting platform, and a pressing and rolling platform for glue, which are arranged at intervals along the first direction and are used to carry multiple cores. The feeding platform can position the cores once, and the pasting platform can position the cores twice. The core transplanting component is used to transplant multiple cores simultaneously. The glue feeding and cutting component is used to realize glue feeding and fixed-length cutting. The pasting component is used to paste the side of the core, and the rolling component is used to roll the upper and lower edges of the tape on the upper and lower surfaces of the core respectively. Although this core pasting device can realize automatic pasting, it can only paste one core at a time, and the production efficiency is still low. In addition, since the current equipment can only stick adhesive strips in one direction, it mainly sticks adhesive strips to the long sides of rectangular cores, so that the other two short sides of the rectangular cores have no adhesive strips, which easily leads to poor bonding at the short side positions of the cores. Summary of the Invention: In view of the above deficiencies of the prior art, the purpose of the present invention is to provide a core pasting device and its working method, which are reasonably designed and are conducive to realizing the pasting work of multiple groups of cores, greatly improving the working efficiency.

[0017] The battery cell pasting device of the present invention includes a frame 1, a longitudinal guide rail 2 provided on the frame 1, and a transverse guide rail 3 provided on the longitudinal guide rail 2. A transverse sliding seat 4 is installed on the transverse guide rail 3, and the transverse sliding seat 4 slides horizontally on the transverse guide rail 3. A fixed seat 6 driven by a vertical motor 5 and a vertical lead screw to lift is provided on the transverse sliding seat 4. Under the action of the vertical motor 5, the fixed seat 6 can lift. A swing seat 7 driven by a swing mechanism to reciprocally rotate 90 degrees is provided on the fixed seat 6, and a plurality of suction heads 8 for adsorbing the battery cell adhesive tape A are provided on the swing seat 7.

[0018] A centering mechanism for the battery cell adhesive tape A is provided at the front section of the swing seat 7 and the suction head 8. This centering mechanism is used to center and arrange the battery cell adhesive tape A conveyed from the previous process to facilitate the subsequent adsorption of the suction head 8 at the accurate position.

[0019] The battery cell B is arranged on the conveyor belt C to move intermittently. Since the orientation of the battery cell B on the conveyor belt C remains unchanged, when it is necessary to paste the battery cell adhesive tape A on the long side and the short side of the rectangular battery cell B, then the rotation mechanism needs to act. Through the action of the swing seat in this application, the suction head 8 can be rotated 90 degrees from the battery cell adhesive tape adsorbed by the centering mechanism, so as to meet the requirement of placing the battery cell adhesive tape A on the long side and the short side of the battery cell B.

[0020] A first guide rail 9 is installed on the bottom surface of the swing seat 7, and a plurality of sliding plates 10 slidably connected to the first guide rail are provided. A telescopic mechanism 11 for driving the sliding plates to approach or move away from each other is provided between adjacent two sliding plates. To adsorb the battery cell adhesive tape located on the centering mechanism in the state where each sliding plate approaches relatively, and release the battery cell adhesive tape onto the surface of the short side of the battery cell B on the conveyor belt C in the state where each sliding plate moves away relatively (the distance between the two short sides of the rectangular battery cell B is large), and release the battery cell adhesive tape onto the surface of the long side of the battery cell B on the conveyor belt C in the state where each sliding plate approaches relatively (the distance between the two long sides of the rectangular battery cell B is short).

[0021] Specifically, four groups of slide plates 10 are provided on the bottom surface of the swing base 7. The first group of slide plates 101 is fixed on the first guide rail 9. On the first group of slide plates, a first telescopic cylinder 12 and a second telescopic cylinder 13 are arranged in opposite directions. The free ends of the telescopic rods of the telescopic cylinders are fixedly connected to the second group of slide plates 102 and the third group of slide plates 103 adjacent to the first group of slide plates. A third telescopic cylinder 14 is fixedly provided on the third group of slide plates.

The second end of the swing arm 19 is fixedly connected to a rotation center shaft 20. The lower end of the rotation center shaft 20 is fixedly connected to the swing base 7. The middle part of the rotation center shaft is rotatably connected to the machine frame. Through the telescopic action of the fourth telescopic cylinder 18, the swing arm 19 is driven to rotate, and then the rotation center shaft 20 and the swing base 7 are driven to rotate. A limit plate 21 and a limit pin 22 installed on the limit plate are provided on the machine frame. Due to the inertia of motion during the rotation process, through the limiting action of the limit pin 22, it is beneficial to ensure the accuracy of the rotation angle.

[0023] Specifically, the action of the horizontal sliding seat 4 is realized by the following structure. The horizontal guide rail 3 is fixedly installed on the horizontal beam 23. A horizontal rotating shaft 24 is provided on the horizontal beam 23. Horizontal gears 25 are provided at both ends of the horizontal rotating shaft 24.

A first synchronous pulley 27 is fixedly provided in the middle of the horizontal rotating shaft 24. A second synchronous pulley 28 driven by a motor and synchronized with the first synchronous pulley 27 is provided on the horizontal beam. The motor drives the first synchronous pulley 27 and the second synchronous pulley 28 to rotate synchronously, and then drives the horizontal rotating shaft 24 and the horizontal gears 25 to rotate. The horizontal gears 25 are meshed with the longitudinal rack 26 to realize the movement of the horizontal beam 23 along the length direction of the longitudinal guide rail 2 and the longitudinal rack 26.

[0024] The transverse sliding seat 4 moves along the transverse guide rail 3 on the transverse beam 23. Specifically, to drive the movement of the transverse sliding seat 4, a gear driven by a motor can be provided on the transverse sliding seat 4, and a rack parallel to the transverse guide rail 3 can be provided on the transverse beam 23. The movement is achieved through the meshing of the gear and the rack, or it can also be driven by a trackless cylinder.

[0025] To realize the lifting of the fixed seat, specifically through the following structure, a top plate 29 is installed on the transverse sliding seat 4. Below both sides of the top plate 29, inner side plates 30 are fixedly installed. The middle of the top plate 29 is rotatably connected to the lower end of the vertical lead screw 31. The top plate 29 is fixed on the transverse sliding seat 4 and has no axial movement relative to the vertical lead screw 31. A lead screw nut 32 is threadedly connected to the vertical lead screw 31. The lead screw nut 32 is fixedly connected to the upper cross plate 33. Below both sides of the upper cross plate 33, outer side plates 34 are fixedly installed. On the inner side surface of the outer side plate 34, a vertical guide rail 35 is fixedly installed. On the outer side surface of the inner side plate, a vertical slider 36 that cooperates with the vertical guide rail for lifting and sliding is fixedly provided. The fixed seat 6 is fixedly installed at the lower end of the outer side plate 34. On the upper cross plate, four guide sleeves 37 are arranged in an array. A guide rod 38 is arranged in the guide sleeve. The lower end of the guide rod is fixed on the top plate 29, and the upper end of the guide rod 38 is fixed on the upper top plate 39. The vertical motor 5 is fixedly installed on the upper top plate 39. Driven by the vertical motor, the vertical lead screw 31 rotates, and then drives the lead screw nut 32, the upper cross plate 33, the outer side plate 34, and the fixed seat 6 to move up and down. Since the position where the suction head adsorbs the rubber strip needs to be precise, through the sliding cooperation between the vertical slider 36 on the inner side plate and the vertical guide rail 35 on the outer side plate 34, and the sliding cooperation between the guide rod 38 and the guide sleeve 37, the lifting of the fixed seat 6 is more stable and smooth, ensuring the accurate position where the suction head adsorbs the rubber strip.

[0026] The specific structure of the centering mechanism 40 described above includes a seat plate 41 provided on the frame, a mounting plate 42 provided on the seat plate, a transverse push plate 43 provided on the seat plate, and a longitudinal push plate 44 provided on the seat plate. The mounting plate 42 has a plurality of limiting plate pieces 45 for limiting the battery cell rubber strips sent by the manipulator. As shown in the figure, there are 8 limiting plate pieces 45. The limiting plate pieces 45 are L-shaped and are used to limit the two right-angle sides of the battery cell rubber strip. The transverse push plate 43 and the longitudinal push plate 44 are respectively driven to slide by a transverse cylinder 46 and a longitudinal cylinder 47 that are perpendicular to each other. A plurality of transverse push pieces 48 are installed on the transverse push plate 43. A plurality of longitudinal push pieces 49 are installed on the longitudinal push plate 44. The transverse push pieces and the longitudinal push pieces are respectively opposite to the two side edges of the limiting plate pieces. Thus, when the transverse push pieces and the longitudinal push pieces are pushed by the transverse cylinder and the longitudinal cylinder, the two right-angle sides of the battery cell rubber strip are abutted against the limiting plate pieces, realizing the alignment of the positions of each battery cell rubber strip.

[0027] Working principle of the cell pasting device of the present invention: Through the action of the swing seat, the cell adhesive tape adsorbed by the adsorption head can be rotated by 90 degrees, so as to meet the requirement that the rectangular cell can be pasted with adhesive tape on both the long side and the short side.
