DETAILED DESCRIPTION
[0022] In order to facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.
[0023] The present application proposes a double-sided glue binding device for a battery cell electrode, which is used to bind the two sides of the battery cell electrode with adhesive tape, including: a first glue-dispensing wheel group 10, a second glue-dispensing wheel group 20, a punching assembly 30, a horizontally rotating glue-sucking assembly 40, a vertically flipping glue-sucking assembly 50, a manipulator and a frame. The first glue-dispensing wheel group 10, the second glue-dispensing wheel group 20, the punching assembly 30, the horizontally rotating glue-sucking assembly 40 and the vertically flipping glue-sucking assembly 50 are all arranged on the frame. The first glue-dispensing wheel group 10 and the second glue-dispensing wheel group 20 are arranged at intervals, and the punching assembly 30 is arranged between the first glue-dispensing wheel group 10 and the second glue-dispensing wheel group 20, so that the punching assembly 30 can punch and cut the adhesive tapes on the first glue-dispensing wheel group 10 and the second glue-dispensing wheel group 20 respectively.
[0024] Among them, a film roll is placed on the first glue-dispensing wheel group 10, and another film roll is placed on the second glue-dispensing wheel group 20. The first glue-dispensing wheel group 10 and the second glue-dispensing wheel group 20 will automatically release a certain length of glue strips to match the working efficiency of the horizontally rotating glue-absorbing component 40 and the vertically flipping glue-absorbing component 50, so as to avoid the tape being released too quickly, resulting in the tape being too long and becoming tattered. The robot grabs the battery cell pole piece and processes it to the horizontally rotating glue-absorbing component 40 and the vertically flipping glue-absorbing component 50. The punching component 30 punches the tape on the first glue-dispensing wheel group 10 and the second glue-dispensing wheel group 20 to form small sections of glue strips, so that the horizontally rotating glue-absorbing component 40 and the vertically rotating glue-absorbing component can absorb the glue strips without pulling up the entire tape, or the punching component 30 causing damage to the battery cell pole piece, resulting in a risk of product defects.
[0025] Specifically, see Figure 1 and Figure 2 The horizontally rotating glue sucking assembly 40 includes a horizontal glue sucking member 41, a horizontal holding driving member 42, and a horizontal rotating driving member 43. The horizontal holding driving member 42 is driven and connected to the horizontal glue sucking member 41, so that the horizontal glue sucking member 41 is held forward or retracted, and is used to hold the horizontal glue sucking member 41 to absorb the glue strip on the first glue-releasing wheel group 10. The horizontal rotating driving member 43 is also driven and connected to the horizontal glue sucking member 41, and is used to horizontally rotate the horizontal glue sucking member 41 after absorbing the glue strip, so that the horizontal glue sucking member 41 can rotate in the horizontal direction. Preferably, the horizontal rotating driving member 43 is a motor, and the horizontal holding driving member 42 is a cylinder.
[0026] Wherein, the vertical flip glue suction assembly 50 comprises a vertical glue suction part 51, a vertical supporting driving member 52 and a vertical rotating driving member 53. The vertical supporting driving member 52 and the vertical rotating driving member 53 are respectively driven and connected with the vertical glue suction part 51, and the vertical supporting driving member 52 is driven and connected with the vertical glue suction part 51 so that the vertical glue suction part 51 is supported or retracted forward, and is used to support the vertical glue suction part 51 to absorb the adhesive strip on the second glue-releasing wheel group 20. The vertical rotating driving member 53 is also driven and connected with the vertical glue suction part 51 so that the vertical glue suction part 51 can be rotated in the vertical direction, and is used for the horizontal glue suction part 41 after the vertical rotation adsorption adhesive strip, so that the single adhesive surface of the adhesive strip on the horizontal glue suction part 41 and the vertical glue suction part 51 is relatively arranged. Preferably, the vertical rotating driving member 53 is a motor, and the vertical supporting driving member 52 is a cylinder.
[0027] The robot arm grabs the cell electrode and places it between the horizontal adhesive suction component and the vertical adhesive suction component 51, that is, the robot arm grabs the cell electrode between the two adhesive strips. The adhesive strip on the vertically flipped adhesive suction component 50 and the adhesive strip on the vertical adhesive suction component 51 are closed toward the cell electrode, so that the two opposite sides of the cell electrode are pressed together and attached with adhesive tape strips, thereby ensuring the insulation of both sides of the cell electrode, improving the efficiency of attaching adhesive tape to both sides of the cell electrode, saving the floor space of the production line equipment, and achieving good adhesive binding effect, realizing full automation.
[0028] In one embodiment, please refer again to Figure 1 The first rubber-depositing wheel assembly 10 includes a first rubber-depositing wheel 11 and a second rubber-depositing wheel 12. The first rubber-depositing wheel 11 and the second rubber-depositing wheel 12 are rotatably mounted on a frame. A film roll is mounted on the first rubber-depositing wheel 11. The adhesive tape on the film roll is wound around the second rubber-depositing wheel 12. The adhesive tape adheres to the outer surface of the second rubber-depositing wheel 12 through its adhesive surface. The punching assembly 30 punches the adhesive tape on the second rubber-depositing wheel 12 at intervals to form a plurality of rubber strips.
[0029] Furthermore, the second rubber-depositing wheel assembly 20 includes a third rubber-depositing wheel 21 and a fourth rubber-depositing wheel 22. The third and fourth rubber-depositing wheels 21 and 22 are rotatably mounted on a frame. Another film roll is mounted on the third rubber-depositing wheel 21. The adhesive tape on the film roll is passed through the fourth rubber-depositing wheel 22 and adheres to the outer surface of the fourth rubber-depositing wheel 22 via its adhesive surface. The punching assembly 30 punches the adhesive tape on the fourth rubber-depositing wheel 22 at intervals to form a plurality of adhesive strips.
[0030] It should be noted that the film is an electrical tape. After the battery cell electrodes are pasted with the film, the insulation of the battery cell electrodes can be ensured.
[0031] Furthermore, receiving portions 31 are spaced apart on the outer sides of the second and fourth rubber-depositing wheels 12, 22. Each receiving portion 31 is inserted into the outer sides of the second and fourth rubber-depositing wheels 12, 22 along its length, with the length of the receiving portion 31 being parallel to the axis of the second and fourth rubber-depositing wheels 12, 22. Adhesive tape is wound around each receiving portion 31, and each receiving portion 31 is provided with a groove. The punching assembly 30 punches the tape toward the groove on each receiving portion 31, forming segments of adhesive strips, such that each segment of adhesive strip is adhered to both ends of the receiving portion 31. Preferably, the receiving portion is a plurality of support bars, each of which is inserted into the second and fourth rubber-depositing wheels 12, 22 in parallel.
[0032] In one embodiment, please refer again to Figure 1 and Figure 2 The first rubber-laying roller assembly 10 further includes a first guide rod 13 and a first rubber-laying drive 14. The first guide rod 13 is rotatably mounted on the frame, wherein the first guide rod 13 is disposed between the first rubber-laying roller 11 and the second rubber-laying roller 12. The adhesive tape is sequentially wound around the first guide rod 13 and the second rubber-laying roller 12. The first rubber-laying drive 14 is drivably connected to the second rubber-laying roller 12. The first rubber-laying drive 14 drives the second rubber-laying roller 12 to rotate on the frame, allowing the second rubber-laying roller 12 to transfer the adhesive tape wrapped around its side. Simultaneously, the adhesive tape from the first rubber-laying roller 11 is continuously transferred to the second rubber-laying roller 12. The punching assembly 30 reciprocally cuts the adhesive tape transferred from the second rubber-laying roller 12. Similarly, the second rubber-laying roller assembly 20 further includes a rotatable second guide rod 23 and a second rubber-laying drive 24. The adhesive tape is sequentially wound around the second guide rod 23 and the fourth rubber-laying roller 22. The second adhesive dispensing drive 24 is drivably connected to the fourth adhesive dispensing wheel 22. The second adhesive dispensing drive 24 drives the fourth adhesive dispensing wheel 22 to rotate on the frame. The second guide rod 23 is disposed between the third adhesive dispensing wheel 21 and the fourth adhesive dispensing wheel 22, allowing the fourth adhesive dispensing wheel 22 to convey the adhesive tape wrapped around its side. Simultaneously, the adhesive tape from the third adhesive dispensing wheel 21 is continuously conveyed to the fourth adhesive dispensing wheel 22 via the second guide rod 23. The punching assembly 30 reciprocates to cut the adhesive tape conveyed by the fourth adhesive dispensing wheel 22. The first adhesive dispensing drive 14 and the second adhesive dispensing drive 24 are motors.
[0033] Furthermore, both ends of the first guide rod 13 and the second guide rod 23 are provided with limiting rings, and the space between the limiting rings at both ends is used to wrap the tape so that the tape can be limited on the first guide rod 13 and the second guide rod 23 to prevent the tape from falling off the first guide rod 13 and the second guide rod 23.
[0034] Furthermore, the adhesive absorption surfaces of the vertical adhesive absorption component 51 and the horizontal adhesive absorption component 41 are flat, so that the adhesive tape strips on the vertical adhesive absorption component 51 and the horizontal adhesive absorption component 41 can be more firmly attached to the battery cell electrode.
[0035] It should be noted that the vertical glue absorbing component 51 and the horizontal glue absorbing component 41 are provided with adsorption holes on their adhesive surfaces, which are connected to the external air valve device so that the non-sticky side of the adhesive strip is attached to the adhesive surfaces of the vertical glue absorbing component 51 and the horizontal glue absorbing component 41.
[0036] In one embodiment, the double-sided glue binding device for the battery cell electrode further includes a sensor assembly 60, which monitors whether the tape in the second glue-releasing wheel 12 and the fourth glue-releasing wheel 22 is transmitted normally to avoid incorrect transmission of the tape or the lack of glue, in which case the equipment needs to brake and stop working.
[0037] Furthermore, a slide rail is provided below the frame, and the frame is slidably mounted on the slide rail, allowing the double-sided glue binding device for the battery cell electrode sheet to move on the slide rail, coordinating with the production line to operate the battery cell electrode sheet. The frame is also provided with a reset switch and a power switch. The power switch is used to turn power on and off the double-sided glue binding device for the battery cell electrode sheet, and the reset switch resets the double-sided glue binding device to its initial state.
[0038] In addition, multiple groups of the first glue-releasing wheel group 10, the second glue-releasing wheel group 20, the punching assembly 30, the horizontal rotating glue-absorbing assembly 40 and the vertical flipping glue-absorbing assembly 50 can be set on the frame, so that the double-sided glue binding device of the battery cell electrode can further improve the working efficiency.
[0039] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person of ordinary skill in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
