[0034] Combine the following Figure 1-Figure 3 The glue applying device provided in the embodiment of the utility model is described.

[0035] Specifically, the glue sticking device includes a conveying device 1, a support 3, a rotating seat 4, a tensioning assembly 5, a first rotating wheel 6, a first driving structure and a cutting mechanism.

[0036] The conveying device 1 is used to convey the battery cells 2 . For example, the conveying device 1 may be, but is not limited to, a conveyor belt mechanism or a roller conveyor.

[0037] The support 3 is disposed above the conveying device 1 so that the battery cells 2 conveyed by the conveying device 1 can pass under the support 3 .

[0038] The rotating seat 4 is rotatably connected to the support 3, and the tensioning assembly 5 is rotatably connected to the rotating seat 4, and the rotation axes of the tensioning assembly 5 and the rotating seat 4 are coaxially arranged. That is, the rotating seat 4 can rotate relative to the support 3, and the tensioning assembly 5 can rotate relative to the rotating seat 4. The tensioning assembly 5 is used to penetrate the inside of the tape roll and tighten the tape roll.

[0039] The first rotating wheel 6 is rotatably disposed on the rotating seat 4. The first rotating wheel 6 is disposed on the running path of the tape and abuts against the non-adhesive surface of the tape. The first rotating seat 4 is used to press the tape toward the battery cell 2 when the rotating seat 4 rotates toward the direction close to the battery cell 2. For example, Figure 1 As shown, the battery cell 2 is arranged below the first rotating seat 4 . When the rotating seat 4 rotates downward and approaches the battery cell 2 , the first rotating wheel 6 on the rotating seat 4 moves downward with the rotation of the rotating seat 4 to press the tape toward the battery cell 2 .

[0040] The first driving mechanism is connected to the rotating seat 4 and is used to drive the rotating seat 4 to rotate.

[0041] The cutting mechanism is arranged on the support 3 and is used for cutting the adhesive tape.

[0042] The adhesive sticking device provided in the embodiment of the utility model can convey the battery cell 2 through the conveying device 1, the first driving mechanism drives the rotating seat 4 to rotate, the first rotating wheel 6 on the rotating seat 4 presses the tape toward the battery cell 2, the conveying device 1 drives the battery cell 2 to move, under the pulling force of the battery cell 2, the tape on the tape roll is pulled out more, and the tape attached to the battery cell 2 becomes longer and longer. The cutting mechanism can finally cut the tape.

[0043] With such arrangement, the first rotating wheel 6 presses the tape toward the battery cell 2, and the battery cell 2 moves along with the conveying device 1 to pull out the tape on the tape roll, thereby completing the attachment of the tape. Compared with the gluing mechanism in the prior art, the process of gluing by the gluing mechanism and vacuum adsorption of the tape is omitted, thereby simplifying the gluing process and increasing the gluing rate.

[0044] In addition, in the embodiment of the utility model, the tape roll is tightened from the inside by the tensioning component 5 rotatably connected to the rotating seat 4. During the process of pulling out the tape, the tensioning component 5 can rotate simultaneously with the tape roll, so that the tensioning component 5 will not affect the pulling out of the tape. In addition, the tensioning of the tensioning component 5 from the inside will not affect the separation of the tape from the tape roll, so that the tape can be pulled out smoothly.

[0045] In some embodiments provided by the present invention, the glue sticking device further comprises a lifting drive device 7. The support 3 is escalably arranged above the conveying device 1, and the lifting drive device 7 is connected to the support 3, and the lifting drive device 7 is used to drive the support 3 to rise and fall.

[0046] In this embodiment, the support 3 is driven to rise and fall by the lifting drive device 7. On the one hand, it is convenient to adjust the height position of the support 3 according to the different sizes of the battery cells 2, so that the first rotating wheel 6 can reliably and stably press the tape to the battery cell 2, so that the glue sticking device can adapt to the battery cells 2 of different specifications, and the use is more flexible. On the other hand, during the glue sticking process, it is convenient to adjust the height position of the support 3, so that the first rotating wheel 6 on the support 3 can reliably and stably press the tape to the battery cell 2, ensuring smooth glue sticking.

[0047] Optionally, the lifting drive device 7 can be a screw nut mechanism, so that the height position of the support 3 can be accurately adjusted. In addition, the screw nut mechanism has a good anti-loosening effect and improves the stability of the support 3. Of course, the lifting drive device 7 can also be a gear rack mechanism, a cylinder or an oil cylinder.

[0048] In some embodiments provided by the utility model, the glue sticking device further includes a mounting frame 8. The mounting frame 8 is arranged above the conveying device 1, and the mounting frame 8 is provided with a guide structure extending in the height direction of the conveying device 1, the support 3 is slidably matched with the guide structure, and the lifting drive device 7 is respectively connected to the mounting frame 8 and the support 3. In this embodiment, by providing the mounting frame 8 and providing a guide structure on the mounting frame 8 to guide the support 3, the guide structure can bear the lateral load on the support 3, and reduce the load transmitted from the support 3 to the lifting drive device 7.

[0049] Optionally, the mounting frame 8 may be directly connected to the ground, or the mounting frame 8 may also be connected to the frame of the conveying device 1 .

[0050] In some embodiments provided by the utility model, the adhesive laminating device further comprises an adsorption member 9. The adsorption member 9 is used to be connected to the vacuum device, and the adsorption member 9 is provided with an adsorption port, which is arranged on the running path of the adhesive tape and faces the adhesive tape.

[0051] In this embodiment, the adsorption member 9 is used, and the adsorption port of the adsorption member 9 is in the running path of the tape and faces the tape. After the tape is cut, the air in the adsorption member 9 can be sucked by a vacuum device, so that the adsorption port generates suction to adsorb the tape, thereby preventing the tape from shrinking and affecting the next gluing operation.

[0052] Alternatively, if Figure 1 As shown, the suction port faces the first rotating wheel 6 and there is a gap between the suction port and the first rotating wheel 6 for the tape to pass through, that is, the suction port can absorb the adhesive surface of the tape. Of course, the suction port is not limited to being set in the above manner. For example, the suction port can also face the non-adhesive surface of the tape to absorb the non-adhesive surface of the tape.

[0053] refer to Figure 2 As shown, in some embodiments provided by the present invention, the tensioning assembly 5 includes a gas expansion shaft 501 and a rotary joint 502 .

[0054] Among them, the gas expansion shaft 501 is rotatably connected to the rotating seat 4, the gas expansion shaft 501 is connected to the rotary joint 502, and is connected to the air source through the rotary joint 502. The rotary joint 502 is installed on the support 3. It should be noted that the gas expansion shaft 501 and the rotary joint 502 are both products in the prior art. This application does not involve improvements to the gas expansion shaft 501 and the rotary joint 502, and will not be repeated here. For example, the rotary joint 502 usually includes an inner ring and an outer ring that is rotatably matched and connected to the inner ring, wherein the inner ring is mounted on the gas expansion shaft 501 and is connected to the gas expansion shaft 501, and the outer ring is connected to the support 3 and is connected to the air source.

[0055] Since the tape roll needs to rotate 360 ​​degrees without restriction during the process of pulling out the tape, in this embodiment, the air expansion shaft 501 is connected to the air source through the rotary joint 502, and the rotary joint 502 can make the air expansion shaft 501 rotate without restriction and keep connected with the air source. The air source inflates the air expansion shaft 501 through the rotary joint 502, so that the air expansion shaft 501 tightens the tape roll. With this arrangement, when replacing the tape roll, the air source can be controlled to cut off, and after the replacement is completed, the air source can be controlled to supply air.

[0056] Of course, the tensioning assembly 5 is not limited to the form of the above-mentioned air expansion shaft 501. For example, Figure 3 As shown, in other embodiments provided by the present invention, the tensioning assembly 5 includes an expansion core 511 , an expansion sleeve 512 and a threaded member 513 .

[0057] The expansion sleeve 512 is rotatably connected to the rotating seat 4, the interior of the expansion sleeve 512 is set as a tapered hole, and the side wall of the expansion sleeve 512 is provided with a plurality of through grooves penetrating along the direction of the wall thickness, and the plurality of through grooves are distributed along the circumference of the expansion sleeve 512. The outer wall of the expansion core 511 is set as a tapered structure, and the tapered structure cooperates with the tapered hole. The screw member 513 passes through the expansion core 511 and is connected to the expansion sleeve 512, and is used to drive the expansion core 511 to move toward the inside of the expansion sleeve 512.

[0058] In this embodiment, by screwing the screw 513, the screw 513 drives the expansion core 511 to move toward the inside of the expansion sleeve 512, and the outer wall of the expansion core 511 fits with the inner wall of the expansion sleeve 512, driving the side wall of the expansion sleeve 512 to tighten the tape roll outward. With this arrangement, the number of parts of the tensioning assembly 5 is small, making the structure of the tensioning assembly 5 simple and compact, and the fixing method of the screw 513 has a good anti-loosening effect, which can ensure the stability of the tape roll fixation.

[0059] Optionally, the threaded member 513 includes a screw, which passes through the expansion core 511 and is threadedly connected to the expansion sleeve 512. Of course, the threaded member 513 is not limited to being set as a screw. For example, in other embodiments, the threaded member 513 includes a screw and a nut, the screw is threadedly connected, bonded or welded to the expansion sleeve 512, and the screw passes through the expansion core 511 and is threadedly connected to the nut.

The first cylinder 10 is installed on the support 3, and the piston rod of the first cylinder 10 is connected to the rotating seat 4 through the connecting rod 11. For example, the two ends of the connecting rod 11 are respectively hinged to the piston rod of the first cylinder 10 and the rotating seat 4. During the extension and retraction process of the first cylinder 10, the rotating seat 4 is driven to rotate through the first connecting rod 11.

The second cylinder 12 is mounted on the support 3, and the cutter 13 is mounted on the piston rod of the second cylinder 12. In this embodiment, when the tape needs to be cut, the second cylinder 12 drives the cutter 13 to extend, and the cutter 13 contacts the tape to cut the tape. With such a configuration, the number of parts of the cutting mechanism is small, making the structure of the cutting mechanism simple and compact.

[0062] refer to Figure 1 As shown, in some embodiments provided by the present utility model, the glue sticking device further includes a third cylinder 14 and a second rotating wheel 15 .

[0063] The third cylinder 14 is mounted on the support 3, and the second rotating wheel 15 is rotatably mounted on the piston rod of the third cylinder 14.

That is, the second rotating wheel 15 is arranged on the running path of the battery cell 2 and is opposite to the position of the battery cell 2 to be glued.

[0064] In this embodiment, during the gluing process, the third cylinder 14 extends and drives the second rotating wheel 15 to abut against the surface of the battery cell 2, thereby further compressing the tape pasted on the surface of the battery cell 2, thereby ensuring that the pasted tape and the battery cell 2 are more firmly bonded.

In this embodiment, it is convenient to adjust the position of the threaded connection assembly along the T-slot when loosening the threaded connection assembly, that is, the cylinder body can move axially, so as to adjust the position of the cylinder body. Such a setting, for example, is convenient to adjust the position of the first cylinder 10, so that when the first cylinder 10 is extended, the first rotating wheel 6 can reliably contact the battery cell 2, thereby pressing the tape to the battery cell 2. For example, it is convenient to adjust the position of the second cylinder 12, so that when the second cylinder 12 is extended, the cutter 13 can reliably contact the tape, thereby cutting the tape. For example, it is convenient to adjust the position of the third cylinder 14 so that when the third cylinder 14 is extended, the second rotating wheel 15 can reliably contact the battery core 2 , thereby pressing the adhesive tape tightly against the battery core 2 .

[0066] Optionally, the threaded connection assembly includes a screw and a T-nut. The screw passes through the through hole and is threadedly connected to the T-nut arranged in the T-slot, thereby connecting the cylinder body to the support 3.

The head of the T-bolt is arranged in the T-slot, and the screw portion of the T-bolt passes through the through hole and is threadedly connected to the nut, thereby connecting the cylinder body to the support 3.
