The described embodiments are some, but not all, of the embodiments of the present utility model.

[0034] Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the present utility model to be protected, but merely represents the selected embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0035] Embodiment 1

[0036] Please refer to the attached Figure 1-2The present embodiment provides a roll glue preparation mechanism 10 for preparing glue for the roll. The roll 20 after preparation of glue can be wound or unwound for the electrode, including a first glue application module 1 for applying single-sided glue 5 to the roll 20, a second glue application module 2 for applying double-sided glue 4 to the roll 20, and a moving module 3. Exemplarily, the first glue application module 1 and the second glue application module 2 may include a tape reel for storing a tape roll, a tape guide assembly for guiding the tape roll, a tension assembly for controlling the tape by a tension wheel or other tension mechanism, a glue pressing head for pressing the tape onto the roll 20, a cutter, and a drive assembly connected to the cutter, etc. Since they are not the focus of the present embodiment, they will not be described in detail here. Those skilled in the art can set the first glue application module 1 and the second glue application module 2 on their own, and they only need to satisfy the requirement of applying single-sided glue 5 or double-sided glue 4 to the roll 20.

[0037] The mobile module 3 is provided with a first mobile end 301 and a second mobile end 302, and the mobile module 3 is used to drive the first gluing module 1 and the second gluing module 2 to move. Exemplarily, the mobile module 3 can be two independent mobile components, for example, the mobile component can be a combination of a linear guide, a drive motor and a ball screw, or a combination of a linear guide and a hydraulic cylinder or a pneumatic cylinder, and the first mobile end 301 and the second mobile end 302 are respectively arranged on the two mobile components to drive the movement of the first gluing module 1 and the second gluing module 2; the mobile module 3 can also be composed of two mobile components, and the mobile components can be a combination of a screw guide, a gear rack, etc. The first mobile component is arranged along the length direction of the reel 20, and the second mobile component is arranged on the mobile end of the first mobile component, and the first mobile end 301 and the second mobile end 302 are both arranged on the second mobile component. This embodiment does not limit the specific setting method of the mobile module 3, and those skilled in the art can set it by themselves, as long as it is sufficient to drive the first gluing module 1 and the second gluing module 2 to move. The first moving end 301 is connected to the first gluing module 1 to drive the first gluing module 1 to move along the length direction of the reel 20 and apply single-sided tape 5 to the reel 20. The second moving end 302 is connected to the second gluing module 2 to drive the second gluing module 2 to move along the length direction of the reel 20 and apply double-sided tape 4 to the reel 20 where the single-sided tape 5 is applied. The single-sided tape 5 is located between the double-sided tape 4 and the reel 20. Among them, the single-sided tape 5 is attached to the bottom of the reel 20, and the double-sided tape 4 is attached to the single-sided tape 5. At this time, when the reel 20 is reeling the electrode, the double-sided tape 4 will stick and fix the electrode to the reel 20.

[0038] During use, the first mobile end 301 of the moving module 3 first drives the first tape - sticking module 1 along the length direction of the reel 20. The tape - sticking press head of the first tape - sticking module 1 pastes the single - sided tape 5 on the reel 20. After the single - sided tape 5 is pasted, at this time, the second mobile end 302 of the moving module 3 drives the second tape - sticking module 2 to move along the direction of the single - sided tape 5, and pastes the double - sided tape 4 on the single - sided tape 5, completing the preparation of the tape on the reel.

[0039] Preferably, after the taping is completed, the single - sided tape 5 is located in the middle of the double - sided tape 4, and the width of the single - sided tape 5 is less than the width of the double - sided tape 4. On the one hand, it can save tape, and on the other hand, it is also convenient to tear off the double - sided tape 4.

[0040] By setting the moving module 3, the first tape - sticking module 1 and the second tape - sticking module 2, automatic taping can be performed on the reel 20. Among them, the first tape - sticking module 1 can paste the single - sided tape 5 horizontally on the reel 20, and the second tape - sticking module 2 can paste the double - sided tape 4 on the reel 20. The double - sided tape 4 is located above the single - sided tape 5. At this time, when the reel 20 has finished unwinding, only the single - sided tape 5 needs to be torn off to tear off the double - sided tape 4. Compared with the existing tape - preparation operation, the tape - preparation mechanism 10 of this embodiment can realize automatic tape preparation, improve production efficiency. At the same time, it is convenient to tear off the double - sided tape 4, improving the tape - tearing efficiency and the utilization rate of the reel 20.

[0041] Embodiment 2

[0042] The difference between Embodiment 2 and Embodiment 1 is that this embodiment further optimizes the tape - preparation mechanism 10 of the reel, such as Figure 1 As shown, the moving module 3 includes a first moving module 310 arranged along a first direction and a second moving module 320 arranged along a second direction, and the first direction and the second direction are different. Among them, the first moving module 310 and the second moving module 320 can be a combination of a linear guide rail, a driving motor, and a ball screw or a combination of a linear guide rail and a hydraulic cylinder or a pneumatic cylinder, etc. The first direction can enable the tape - sticking module to paste the tape on the length direction of the reel 20. Preferably, the second direction is perpendicular to the first direction.

[0043] The first moving module 310 is drivingly connected to the second moving module 320, and the first moving module 310 can drive the second moving module 320 to move in the first direction; the first moving end 301 and the second moving end 302 are arranged on the second moving module. There can be two second moving modules, with the first moving end 301 arranged on one of the second moving modules and the second moving end 302 arranged on the other second moving module 320. During the glue pasting process, the first moving module 310 can drive the first glue pasting module and the second glue pasting module to move simultaneously or separately through the second moving module 320 to prepare the glue on the surface of the reel. Moreover, the second moving module 320 can drive the first glue pasting module 1 or the second glue pasting module 2 to move in the second direction, such as longitudinally, to avoid the glue pasting module in operation during the glue pasting process. Through this setting, the glue pasting efficiency of the reel 20 can be improved, and the glue preparation process can be completed in one round trip.

[0044] In some embodiments, there are multiple double-sided tapes 4, and the multiple double-sided tapes 4 are spaced apart and distributed at the single-sided tape 5 of the reel 20. The spaced-apart double-sided tapes 4 can save the usage amount of the double-sided tape 4 and at the same time avoid excessive contact area of the double-sided tape 4, making it difficult to tear off. When pasting the double-sided tape 4 at intervals, it can be that the glue pasting module uses a cutter to slit the double-sided tape 4 to form multiple intervals, or it can also be that the double-sided tape strip is multiple double-sided tapes 4 with spaced-apart distribution, and the glue pasting module can be directly used to paste it.

[0045] Reference Figure 2 , in some embodiments, a glue tearing groove 21 for tearing the single-sided tape 5 is provided at the end of the reel 20. The glue tearing groove 21 is provided at both ends of the reel 20, and it can be arranged in a surrounding manner. When pasting the single-sided tape 5 on the reel 20, the single-sided tape 5 will pass through the glue tearing groove 21. When the reel 20 has finished unwinding and the glue needs to be torn off, at this time, only the single-sided tape 5 needs to be torn off from the glue tearing groove 21, improving the glue tearing efficiency.

[0046] In some embodiments, the single-sided tape 5 is a PVC tape. Among them, the PVC tape can firmly adhere to various materials, ensuring the stability of pasting, and it has higher durability and can maintain its stickiness for a longer time.

[0047] Embodiment 3

[0048] The difference between Embodiment 3 and Embodiment 1 is that in this embodiment, the reel glue preparation mechanism is further optimized, such as Figures 3-5As shown in the figure, it includes a reel support frame 30 for placing the reel 20. The straight lines formed at both ends of the reel support frame are parallel to the moving directions of the first moving end and the second moving end. Automatic glue preparation for the reel 20 can be achieved. During use, the reel 20 is placed on the reel support frame 30, and the reel glue preparation mechanism 10 is arranged on one side of the reel support frame to perform automatic glue pasting operation on the reel 20. Preferably, the reel support frame 30 includes two oppositely arranged support plates 31, and a placement portion 32 for placing the reel 20 is arranged at the end of the support plate 31 facing the reel 20. The placement portion 32 can be a V-shaped support bracket. The V-shaped support bracket is used for three-axis positioning of the reel 20. The placement portion 32 can also include a limit block to prevent the reel 20 from falling. The reel 20 can be provided with a placement groove adapted to the V-shaped support to fix the reel 20 and the V-shaped support bracket.

[0049] In some embodiments, a rotation driving member and an air shaft 33 are arranged on one side of the placement portion 32. The rotation driving member is in transmission connection with the air shaft 33, and the air shaft 33 is in transmission connection with the reel 20 to drive the reel 20 to rotate. The air shaft 33 can fix the reel 20. The rotation driving member can be a motor, a servo motor, etc. (not marked in the drawings). During use, the rotation driving member drives the air shaft 33 to rotate, and then drives the reel 20 to rotate, so that the reel 20 rotates to an appropriate glue pasting position to paste glue on the reel 20, improving the efficiency of glue preparation.

[0050] In some embodiments, a positioning sensor 34 for positioning the reel 20 is arranged on the reel support frame 30. Among them, the positioning sensor 34 is a color mark sensor. There are positioning points on the reel 20, and the color mark sensor can identify the positioning points of the reel 20 to accurately position the reel 20.

[0051] In some embodiments, it further includes a feeding module 40 for feeding the reel. The feeding module 40 is arranged on one side of the support frame. Among them, the feeding module 40 can be a robotic arm, an AGV feeding trolley, etc. Exemplarily, the feeding module 40 is an AGV feeding trolley. The AGV feeding trolley can automatically identify the loading and unloading stations depending on the labels pre-pasted at the fixed positions of the reel 20. After moving to the loading and unloading stations, the unloading arm clamps the empty reel 20, the air shaft 33 releases and retracts, and the AGV feeding trolley fixes the empty reel 20 to perform loading and unloading operations on the reel 20. For the reel 20 that has been prepared with glue, operations such as automatic storage, centralized storage, or winding can be performed on it.

[0052] During the use of this embodiment, first, the winding reel 20 is fixed to the placement part 32 of the winding reel support frame 30 by the AGV loading trolley. At this time, the air shaft 33 expands to fix the winding reel 20. The rotation driving part drives the winding reel 20 to rotate and makes it rotate to the relative position. The first adhesive pasting module 1 first pastes a single-sided adhesive 5 on the winding reel 20, and then the second adhesive pasting module 2 pastes a double-sided adhesive 4 on the winding reel 20 to complete the automatic adhesive preparation.

[0053] The winding reel adhesive preparation mechanism of this embodiment can realize the automatic loading and unloading of the winding reel 20 and the automatic adhesive pasting process, improve the adhesive preparation efficiency, and improve the automation degree of the equipment.
