Description

Technical Field

[0001] The utility model relates to the technical field of core package preparation, in particular to a glue dripping hose and a winding core package tailing device. Background Art

[0002] In the lithium battery industry in the new energy field, the types of batteries used vary depending on the application scenarios. In the energy storage field, square aluminum shell batteries are mostly used. This type of battery mainly uses a winding process. After the core package is wound, in order to prevent it from loosening, the diaphragm at the end and the core package body need to be fixed. The fixed core package can ensure its own integrity during the flow to the subsequent process, reduce safety hazards, and increase the production line quality rate.

[0003] The invention patent with the existing authorization announcement number CN110176620B discloses a method for controlling the end-of-life of a battery cell substrate. The substrate is fed toward a winding device along a second direction, and the winding device winds up the substrate. The method for controlling the end-of-life of the battery cell substrate includes the following steps: S1. In the final stage of substrate winding, the substrate is clamped and moved away from the winding device to maintain a certain tension; S2. Cutting is performed on the side of the substrate clamping position away from the substrate winding position; S3. While the winding device continuously winds up the substrate, the substrate is moved toward the winding device while maintaining a certain tension.

[0004] The above technical solution discloses the finishing cutting operation after the core package is wound. In addition, the tail end of the core package needs to be fixed to avoid the core package from being scattered. The current finishing method mostly uses tape for bonding, but since the tape has a certain thickness, it will affect the margin of the battery cell group. At the same time, the ceramic coating on the core package diaphragm has poor adhesion to the tape, and the tape is easy to fall off, which will affect the subsequent process. After the core package is assembled into the battery cell shell, the tape is easy to fall off due to immersion in the electrolyte, affecting the performance of the battery cell.

DETAILED DESCRIPTION

[0044] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] like Figures 1 to 6 As shown, the dripping tube of the present invention comprises a dripping tube 1, a fixing member 2, a flow guide member 3 and a plug connector 4;

[0046] The winding core package finishing device of the present invention comprises a first driving member 5, a pressure roller 6 and a second driving member 7, wherein the core package is formed by winding a diaphragm and a pole piece.

[0047] like Figure 3 and Figure 5 As shown, a drip hole 101 is formed on the surface of the dropper 1; a fixing member 2 is sleeved on the dropper 1; the flow guide 3 includes a guide rod 31 and a connecting rod 32, the end of the guide rod 31 facing the drip hole 101 and perpendicular to the axis of the dropper 1; at least two connecting rods 32 are provided, and one end of each connecting rod 32 is connected to the end of the guide rod 31 to form an arrow-shaped structure pointing away from the dropper 1, and the other end of the connecting rod 32 is connected to the fixing member 2;

[0048] As shown in the above structure, the dropper 1 is used for glue injection. When the viscous solution is supplied into the dropper 1, the viscous solution will overflow through the drip hole 101. At this time, under the guidance of the guide rod 31 in the guide member 3, the surface tension of the overflowing viscous solution can be eliminated, so that the solution quickly flows down through the guide rod 31 and drips to the tail end of the core package. After that, the tail end of the core package is smoothed, thus completing the finishing work of the tail end of the core package.

[0049] The fixing member 2 is used to fix the flow guide member 3 to the dropper 1 .

[0050] like Figure 5 As shown, the fixing member 2 includes multiple sleeves 21 and a connecting plate 22. The surface of the dropper 1 is provided with multiple drip holes 101 in an array along the axis. The sleeves 21 are sleeved and fixed on the dropper 1. The multiple sleeves 21 are spaced apart and located between two adjacent drip holes 101. The connecting plate 22 is connected to the multiple sleeves 21, and the connecting plate 22 has notches 201 corresponding to the drip holes 101. The connecting rod 32 is connected to the connecting plate 22 and / or the sleeve 21.

[0051] As in the above structure, during assembly, the fixing member 2 is mounted on the dropper 1 through the sleeve 21, and the notch 201 is aligned with the drip hole 101. At this time, the guide rod 31 of the guide member 3 is aligned with the drip hole 101. The viscous solution overflowing from the drip hole 101 will pass through the notch 201 and directly contact the guide rod 31, thereby achieving guidance.

[0052] In this structure, the sleeve 21 is interference fit with the dropper 1, or a bolt is directly provided on the sleeve 21, the bolt is threadedly matched with the sleeve 21, and passes through the sleeve 21 to abut against the dropper 1, thereby achieving the connection and fixation of the dropper 1, the fixing member 2 and the guide member 3.

[0053] Specifically, the fixing member 2 and the flow guide member 3 are provided as an integral structure by injection molding.

[0054] like Figures 1 to 4 and Figure 6 As shown, the plug connector 4 is a quick plug for the water pipe, and the plug connector 4 is detachably connected to the dropper 1 and is connected to each other;

[0055] As shown in the above structure, the plug connector 4 is used to connect the glue supply pipeline to facilitate the glue storage container to supply the viscous solution into the dropper 1; since the plug connector 4 adopts a quick plug, it is convenient to directly plug in the glue supply pipeline.

[0056] like Figure 5 As shown, the dropper 1 is a stepped tube, comprising a large diameter section 11 and a small diameter section 12 connected to each other, wherein the drip hole 101 is provided on the small diameter section 12, the sleeve 21 is sleeved on the small diameter section 12, and the sleeve 21 abuts against the stepped surface of the dropper 1; the plug connector 4 is connected to the large diameter section 11 by a thread;

[0057] As in the above structure, by setting the dropper 1 as a stepped tube, the step surface of the stepped tube can be used to limit the fixing member 2, and the end of the sleeve 21 can be directly pressed against the step surface, so that the guide rod 31 can be accurately aligned with the drip hole 101;

[0058] At the same time, in this structure, the inner holes of the large diameter section 11 and the small diameter section 12 are set to be equal diameters. The large diameter section 11 has a larger pipe wall thickness, which is convenient for setting the threaded connection plug 4, while the pipe wall thickness of the small diameter section 12 is smaller, which facilitates the rapid overflow of the viscous solution, thereby reducing the probability of blockage and making it easier to clean.

[0059] like Figures 1 to 3 As shown, the first driving member 5 is used to drive the glue dripping tube to rotate along the axial direction of the dripping tube 1;

[0060] In the above structure, since the viscous solution is supplied through one end of the dropper 1, more viscous solution will overflow from the drip hole 101 near the end of the plug connector 4. After the first driving member 5 is provided, the first driving member 5 drives the dropper 1 to rotate so that the drip hole 101 faces upward. At this time, the viscous solution is supplied to fill the inner cavity of the dropper 1.

[0061] When the core package is transferred to the glue dripping station, the dropper 1 is rotated so that the dripping hole 101 faces downward, and then the viscous solution overflows and drips to the tail end of the core package, thereby ensuring uniform glue dripping.

[0062] Specifically, the first driving member 5 includes a driven gear 51, a driving gear 52 and a motor 53, wherein the driven gear 51 is provided on the fixed member 2; the driving gear 52 is meshed with the driven gear 51; and the main shaft of the motor 53 is connected to the driving gear 52;

[0063] As in the above structure, when working, the motor 53 drives the driving gear 52 and the driven gear 51 to rotate, which can drive the dropper 1, the fixing member 2 and the flow guide member 3 to rotate together, thereby realizing the flipping action.

[0064] like Figure 6 As shown, the pressure roller 6 includes an inner roller 61 and a flexible sleeve 62, wherein the inner roller 61 is a rigid roller; the flexible sleeve 62 is sleeved on the inner roller 61; the second driving member 7 is used to drive the pressure roller 6 to move;

[0065] As in the above structure, the pressure roller 6 is used to smooth the tail end of the core package so that the tail end is firmly attached to the wound core package; in this structure, the second driving member 7 drives the pressure roller 6 to move, and the flexible sleeve 62 presses the tail end of the core package to smooth it.

[0066] Specifically, the flexible cover 62 may be a sponge cover.

[0067] Specifically, the second driving member 7 is a cylinder;

[0068] In some embodiments, the second driving member 7 may also be a connecting rod, an electric push rod or other driving members.

[0069] Specific implementation steps:

[0070] The pole piece and diaphragm are wound to form a core package, which is then transferred to the glue dripping station by a robot. A viscous solution is fed into the dropper 1. The viscous solution overflows through the drip hole 101 and drips to the tail end of the core package under the guidance of the guide member 3. The core package is then transferred to the pressure roller 6, which is driven by the second driving member 7 to move and smooth the tail end of the core package.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
