Description

Technical Field

[0001] The utility model relates to the technical field of battery production equipment, in particular to a full-body gluing mechanism for battery packs. Background Art

[0002] A soft-pack lithium battery is just a liquid lithium-ion battery covered with a polymer shell. Structurally, it uses an aluminum-plastic film for packaging. In the case of potential safety hazards, the soft-pack battery will at most bulge and crack. The shape of the soft-pack battery is square, and the size of this kind of battery can be very small. After these soft-pack batteries are wrapped with aluminum-plastic film, adhesive tape needs to be pasted on the outside to prevent the aluminum-plastic film from spreading. When laminating the soft-pack battery, the adhesive tape must be firmly pasted on the outer peripheral surface of the soft-pack battery. If the paste is not firm, quality problems such as bulging and air bubbles will occur. There are some devices on the market that can apply glue (laminate) to soft-pack batteries. However, these devices mainly rely on pressing rollers on the adhesive tape on the battery surface to achieve pasting. This design can only roll-press the larger top and bottom surfaces of the soft-pack battery, but for the smaller side surfaces, it is impossible to paste them by rolling. Therefore, relying solely on the rolling method cannot ensure that the adhesive tape is firmly pasted on the soft-pack battery, and quality problems are likely to occur.

[0003] For example, the battery laminating device disclosed in Chinese Patent Application No.: CN202221691996.1. Its roller-pressing film device is used to press the film material on the battery. It can only roll-press the larger top and bottom surfaces of the soft-pack battery, but for the smaller side surfaces, it is impossible to paste them by rolling. Therefore, relying solely on the rolling method cannot ensure that the adhesive tape is firmly pasted on the soft-pack battery, and quality problems are likely to occur.

[0004] Another example is a flexible roller-pressing device for a square-shell lithium battery laminating machine disclosed in Chinese Patent Application No.: CN202210979122.4, which also uses the rolling method for laminating, and has the same above problems. Summary of the Utility Model

[0028] Please refer to Figures 1 to 6 as shown, which shows the specific structure of the preferred embodiment of the present utility model, and is a full-body gluing mechanism for a battery pack.

[0029] Among them, the glue sucking module 120 sucks the adhesive tape 11 on the glue feeding module 110, and then pastes the adhesive tape 11 on the top surface of the battery 12 in the first feeding device 20. The flipping device 30 connects the first feeding device 20 and the second feeding device 40. The flipping device 30 turns the bottom surface of the battery 12 upwards, and then the battery 12 with the bottom surface upwards is transferred by the flipping device 30 to the second feeding device 40. The second feeding device 40 clamps the battery, and the adhesive tape 11 is firmly pasted on the side surface of the battery 12. The glue rolling device 50 rolls the adhesive tape 11 on the battery 12 in the second feeding device 40, so that the entire adhesive tape 11 can be firmly pasted on the side surface of the battery 12.

[0030] The present application provides a full-body gluing mechanism for a battery pack, which includes a glue feeding device 10, a first feeding device 20, a flipping device 30, a second feeding device 40, and a glue rolling device 50; the glue feeding device 10 includes a glue feeding module 110 and a glue sucking module 120, and the glue sucking module 120 can suck the adhesive tape 11 on the glue feeding module 110 and stick the adhesive tape 11 on the battery 12 in the first feeding device 20; the flipping device 30 connects the first feeding device 20 and the second feeding device 40; the first feeding device 20 and the second feeding device 40 can clamp the battery; the glue rolling device 50 is arranged beside the second feeding device 40, and the roller 54 of the glue rolling device 50 can roll and press the adhesive tape 11 on the battery 12 in the second feeding device 40. In this embodiment, the glue sucking module 120 is arranged above the glue feeding module 110. When working: 1. The first feeding device 20 clamps the battery 12. 2. The glue feeding module 110 conveys the adhesive tape 11 and cuts off the adhesive tape 11 of a preset length. 2. The glue sucking module 120 sucks the cut adhesive tape 11 on the glue feeding module 110, and then sticks the adhesive tape 11 on the top surface of the battery 12 in the first feeding device 20. 3. The flipping device 30 transfers the battery 12 from the first feeding device 20 to the second feeding device 40, and can also turn over the battery 12 at the same time. That is, when the battery 12 is in the second feeding device 40, the bottom surface is upward. 4. The flipping device 30 transfers the battery 12 to the second feeding device 40, and the second feeding device 40 clamps the battery 12. At this time, the adhesive tape 11 on the side of the battery 12 will be firmly attached to the side of the battery 12 due to the clamping of the second feeding device 40. 5. The roller 54 of the glue rolling device 50 rolls and presses the adhesive tape 11 on the battery 12 (with the bottom surface upward at this time) in the second feeding device 40, so that the adhesive tape 11 can be firmly stuck on the battery 12. It can be seen that in this design, the adhesive tapes 11 on the top surface, bottom surface, left and right side surfaces of the battery 12 are all firmly stuck, and the sticking quality is good.

[0031] Preferably, the glue feeding module 110 includes a glue pulling bracket 111, a glue paper clip 114, a cutter 115, and a glue fixing seat 116; the glue paper clip 114 is arranged on the glue pulling bracket 111; the glue pulling bracket 111 is connected to the output end of the first driving source 117, and the first driving source 117 drives the glue pulling bracket 111 to move forward or backward; the glue fixing seat 116 is arranged beside the glue paper clip 114; the cutter 115 is arranged between the glue fixing seat 116 and the glue paper clip 114 and can cut the glue paper 11. The glue fixing seat 116 is provided with a glue wheel 118 and suction holes, and the glue fixing seat 116 can move away from or close to the glue paper clip 114. The glue paper is very smooth and will not stick to the glue wheel. The glue wheel 118 has a guiding function and can make the glue paper extend to the glue fixing seat 116 more smoothly. More specifically, the glue pulling bracket 111 is provided with a glue guiding wheel 112 and a glue guiding frame 113; the glue paper 11 passes through the glue guiding wheel 112, the glue guiding frame 113, and the glue paper clip 114 in sequence. The working principle of the glue feeding module 110 is as follows: 1. The adhesive tape comes out from the material tray and then passes through the glue guiding wheel 112, the glue guiding frame 113, and the glue paper clip 114 in sequence, and the glue paper clip 114 clamps the glue paper 11. 2. The first driving source 117 (preferably a cylinder) drives the glue pulling bracket 111 to move forward, and then the glue paper 11 extends to the glue fixing seat 116. 3. The glue fixing seat 116 sucks the glue paper 11, and then the cutter 115 driven by a cylinder cuts the glue paper 11. Subsequently, the first glue fixing seat cylinder drives the glue fixing seat 116 to move away from the glue paper clip 114, and the second glue fixing seat cylinder drives the glue fixing seat to rise a certain distance. 4. The vacuum suction holes on the glue suction seat 122 on the first manipulator 121 of the glue suction module 120 suck the glue paper 11 on the glue fixing seat 116, and then paste the glue paper 11 on the top surface of the battery 12 in the first feeding device 20. 5. The glue paper clip 114 driven by a cylinder loosens the glue paper clip 114. At the same time, the first driving source 117 drives the glue pulling bracket 111 to move backward, the glue paper clip 114 closes again, and then the glue pulling bracket 111 moves forward, so that the glue paper 11 can be continuously conveyed to the glue fixing seat 116.

[0032] More preferably, the glue suction seat 122 is installed on the first manipulator through a spring mounting seat 123. This design enables the glue suction seat 122 to obtain a certain buffer space when sucking the glue paper 11 on the glue fixing seat 116, and the glue fixing seat 116 can also press on the glue fixing seat 116 with a certain force to ensure successful adsorption of the glue paper 11 without deviation.

The linear module 32 is preferably a cylinder-driven module, and it can also be understood that the cylinder directly drives the second driving source 33 to move back and forth between the first feeding device 20 and the second feeding device 40, which can avoid interference and is more convenient to work. The lifting platform 31 is preferably a lifting platform 31 driven by a screw servo motor or a motor. The second driving source 33 is preferably a rotary cylinder / servo motor. The third driving source 34 is preferably a rotary finger cylinder / servo motor, which can be used to drive the transfer fixture 35 to rotate and clamp. Working principle of the flipping device 30: 1. The transfer fixture 35 adjusts its own posture. The first feeding device 20 releases the battery 12, and then the transfer fixture 35 clamps the battery 12 in the first feeding device 20. (As another way, the first feeding device 20 can clamp the battery 12, so the transfer fixture 35 can also adjust the battery direction by rotation and complete the pasting on the side of the battery in the first feeding device 20). 2. The transfer fixture 35 adjusts its own posture so that the bottom surface of the battery 12 faces upward when in the second feeding device 40. 3. The second driving source 33 drives the transfer fixture 35 to swing from the first feeding device 20 to the second feeding device 40, and then the second feeding device 40 clamps the battery 12. At this time, the adhesive tape 11 is firmly attached to the top surface and the left and right side surfaces of the battery 12, waiting for the roller gluing device 50 to roll-press the bottom surface of the battery 12. The whole process is repeated continuously. The position of the supporting portion 86 can be adjusted by screws. After the battery is adjusted to the correct position, the supporting portion 86 can support the battery. The supporting portion 86 can not only prevent the battery from falling, but also prevent the battery from deforming when being clamped / inserted. The elongation of the supporting portion 86 is adjustable to adapt to various different sizes of batteries.

During this process, the roller will roll and press the adhesive tape 11. At this point, the adhesive tape 11 has been firmly pasted on the top surface, bottom surface, left and right side surfaces of the battery 12.

[0035] Preferably, the first feeding device 20 includes a first turntable 21 and a first feeding fixture 22 arranged on the first turntable 21. A first driving block 23 is arranged on the first feeding fixture 22, and the first driving block 23 drives the first feeding fixture 22 to open or close. A third driving source 34 is connected to the first driving block 23 at the bottom of the first turntable 21.

A fourth driving source is connected to the second driving block 43 at the bottom of the second turntable 41. During operation, the second driving block 43 arranged on the second feeding fixture 42 is driven by the fourth driving source, so that the second feeding fixture 42 opens, then the battery 12 is placed in the second feeding fixture 42, and then the second feeding fixture 42 clamps the battery 12 under the action of the spring. The first feeding fixture 22 and the second feeding fixture 42 in this embodiment are preferably stretching clamping fixtures with springs. The third driving source 34 and the fourth driving source in this embodiment are preferably cylinders. Of course, the first feeding fixture 22 and the second feeding fixture 42 can also be without springs and clamp the battery 12 by their own structures.

[0037] In summary, the key design point of the present utility model lies in that the glue sucking module 120 can stick the adhesive tape 11 obtained from the glue feeding module 110 onto the top surface of the battery 12 in the first feeding device 20. The flipping device 30 can transfer the battery 12 in the first feeding device 20 to the second feeding device 40, and at the same time make the bottom surface of the battery 12 face upward. The second feeding device 40 clamps the battery, and the adhesive tape 11 is firmly adhered to the side surface of the battery 12.
