Description

Technical Field

[0001] The utility model relates to the technical field of secondary batteries, in particular to a secondary battery patch recycling tool. Background Art

[0002] Secondary batteries have many advantages such as stable and reliable performance such as voltage and current, simple structure, and easy charging and discharging operations. They are widely used in various aspects of social life and production.

[0003] In the preparation process of secondary batteries, after the battery is coated with a blue film, an insulating top patch needs to be attached to the top of the battery to play an insulating role. However, in actual production, due to accidental factors such as lack of operator experience and uneven force, the insulating top patch is prone to poor lamination, such as deviation in lamination position, and the deviated patch contacts with components such as the battery pole. If the insulating top patch is torn off and discarded, it will lead to an increase in production costs. Therefore, it is usually necessary to recycle the torn off insulating top patch and re-laminate the recycled insulating top patch with the spare release paper so that it can be reused. However, in the prior art, the operator usually performs the re-lamination operation manually, which easily causes an offset between the recycled patch and the spare release paper.

[0036] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments.

[0038] In the description of the present application, unless otherwise specified, “plurality” means two or more.

[0039] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0040] See also Figures 1 to 4 , Figure 1 A three-dimensional view of a secondary battery patch recycling tool provided by the present application is shown; Figure 2 A front view of a secondary battery patch recycling tool provided by the present application is shown; Figure 3 A top view of a patch adapted to the secondary battery patch recycling tooling provided in the present application and bonded to a release paper is shown;

[0041] Figure 4 An exploded view is shown when a patch adapted to the secondary battery patch recycling tooling provided in the present application is separated from the release paper.

[0042] Combine the following Figure 1 and Figure 2 , describes the secondary battery patch recycling tooling provided by the embodiment of the utility model, and combines Figure 3 and Figure 4 , describing the structure of the patch body 501, the backing layer 504 and the release paper 6 adapted to the secondary battery patch recycling tooling.

[0043] It should be noted that if Figure 3 and Figure 4As shown, the patch 5 refers to the insulating top patch set on the top of the battery after the battery is coated with a blue film. When the patch 5 is not put into use, the patch 5 is bonded to the release paper 6 through the adhesive layer 504 for storage; when the patch 5 needs to be pasted on the top of the battery, the release paper 6 is torn off to expose the adhesive layer 504, and then the patch 5 is pasted to the top of the battery through the adhesive layer 504. However, in actual production, due to accidental factors such as insufficient experience of operators and uneven force, the patch 5 is easy to have a poor bonding effect, such as deviation of the bonding position, and the deviated patch 5 is in contact with components such as the battery pole. If the patch 5 is torn off and discarded, it will lead to an increase in production costs. Therefore, it is usually necessary to recycle the torn patch 5, and re-bond the recycled patch 5 with the spare release paper 6 so that it can be reused. However, in the prior art, the operator usually performs the re-bonding operation manually, which easily causes the recovered patch 5 to offset from the spare release paper 6.

[0044] like Figure 1 and Figure 2 As shown, the present application provides a secondary battery patch recycling tool for locating Figure 3 and Figure 4 The patch 5 and release paper 6 are shown, and are used to accurately apply the release paper 6 to the adhesive layer 504 of the patch 5.

[0045] Specifically, the secondary battery patch recycling tooling includes a mounting base 1, and a main body positioning groove 101 and a convex positioning groove 102 are opened at one end of the mounting base 1 along the height direction. The main body positioning groove 101 is used to limit the installation of the patch body 501 and the release paper body 601, and the convex positioning groove 102 is arranged at one end of the main body positioning groove 101 in the length direction, and the convex positioning groove 102 is connected with the main body positioning groove 101, and the convex positioning groove 102 is used to limit the installation of the release paper convex 602.

[0046] By utilizing the secondary battery patch recycling tooling of the present embodiment, a body positioning groove 101 for limiting the installation of the patch body 501 and the release paper body 601 is provided at the mounting seat 1, so that when the patch 5 or the release paper 6 is placed in the mounting seat 1, the patch body 501 or the release paper body 601 can be limited to avoid the displacement of the patch body 501 or the release paper body 601. In addition, by providing a convex positioning groove 102 for limiting the installation of the release paper convex part 602, the release paper convex part 602 can be limited to avoid the displacement of the release paper convex part 602.

[0047] The use process of the secondary battery patch recycling tooling of this embodiment is as follows: when it is necessary to tear off the patch 5 with poor bonding effect from the top of the battery for recycling, the operator first manually tears off the patch 5 from the top of the battery, and the torn patch 5 includes a patch body 501 and a back adhesive layer 504; then the torn patch 5 is placed in the body positioning groove 101 of the secondary battery patch recycling tooling of this embodiment, when placing, the patch body 501 is close to the body positioning groove 101, and the back adhesive layer 504 is away from the body positioning groove 101, that is, the back adhesive layer 504 is placed upwards; then the spare release paper 6 is placed on the secondary battery patch When placed in the main body positioning groove 101 of the patch recycling tool, the release paper body 601 is limited in contact with the back glue layer 504, and the release paper protrusion 602 is limited in the protrusion positioning groove 102, so that the release paper 6 is bonded to the back glue layer 504 on the back of the patch body 501 in an expected posture, avoiding the deviation between the release paper 6 and the patch body 501 during the bonding process, and further avoiding the patch 5 from being damaged when it is subsequently installed on the battery cell. That is, the use of the secondary battery patch recycling tool of this structure can achieve accurate bonding and adhesion between the recycled patch 5 and the spare release paper 6, thereby efficiently completing the recycling of the patch 5.

[0048] like Figure 1 and Figure 2 As shown, the secondary battery patch recycling tool also includes a handle 2, and the handle 2 is provided with an abutting convex portion 201. A gap or contact is left between any outer wall surface of the abutting convex portion 201 and the inner wall surface corresponding to it in the convex positioning groove 102. The abutting convex portion 201 is located at the top of the convex positioning groove 102. Under the action of external force, the abutting convex portion 201 approaches the convex positioning groove 102 until the abutting convex portion 201 is pressed on the convex positioning groove 102. Figure 3 and Figure 4 The release paper 6 shown is located on the surface of the release paper protrusion 602 in the protrusion positioning groove 102 .

[0049] By using the secondary battery patch recycling tooling of the present embodiment, the abutting protrusion 201 is set at the top of the protrusion positioning groove 102, and any outer wall surface of the abutting protrusion 201 is left with a gap or in contact with the inner wall surface corresponding to it in the protrusion positioning groove 102, to ensure that the abutting protrusion 201 can smoothly enter the protrusion positioning groove 102 under the action of external force, and press the surface of the release paper protrusion 602 to limit one end of the release paper 6. At the same time, external force is used to smooth the release paper 6 from the end toward the other end to avoid the release paper 6 from being partially loosely adhered during the pasting process, and further avoid the release paper 6 and the patch body 501 from being offset during the bonding process.

[0050] like Figure 1 and Figure 2As shown, the handle 2 is further provided with a mounting portion 202, which is integrally formed with the abutting protrusion 201, and a distance is left between the mounting portion 202 and the mounting seat 1. Under the action of external force, the abutting protrusion 201 is pressed on the mounting portion 202. Figure 3 and Figure 4 When the release paper 6 shown is located on the surface of the release paper protrusion 602 in the protrusion positioning groove 102 , the mounting portion 202 abuts against the mounting seat 1 ; the mounting portion 202 is fixed to the mounting seat 1 by a fastener.

[0051] In the present application, the fastener is preferably a bolt with external threads. In this case, the handle 2 is provided with a countersunk hole for accommodating the bolt head, and the mounting seat 1 is provided with a threaded hole. The external threaded portion of the bolt is inserted into the countersunk hole and then screwed into the threaded hole until tightened.

[0052] like Figure 2 As shown, the secondary battery patch recycling tool also includes an elastic member 3, and the elastic member 3 is sleeved on the outside of the fastener.

[0053] By utilizing the secondary battery patch recycling tooling of the present embodiment, an elastic member 3 is provided between the mounting portion 202 and the mounting seat 1. When an external force acts on the abutting protrusion 201, the elastic member 3 will be prompted to store energy. After the external force acting on the abutting protrusion 201 is removed, the elastic member 3 releases energy, drives the mounting portion 202 away from the mounting seat 1, and simultaneously drives the abutting protrusion 201 away from the release paper protrusion 602.

[0054] Furthermore, the elastic member 3 is preferably a spring, and the spring is sleeved on the outside of the partial external thread of the bolt.

[0055] By using the secondary battery patch recovery tooling of this embodiment, the mounting portion 202 of the handle 2 and the abutting convex portion 201 are integrally formed and arranged as follows: Figure 1 The symmetrical structure shown in FIG. 1 is achieved by setting the mounting portion 202 of the handle 2 and the abutting protrusion 201 as shown in FIG. Figure 1 The symmetrical structure shown avoids the phenomenon of unilateral warping when external force acts on the handle 2, improves the uniformity of the pressing of the abutting protrusion 201 on the release paper protrusion 602, avoids the phenomenon of partial loose adhesion of the release paper protrusion 602, and improves the bonding quality.

[0056] like Figure 1 and Figure 2 As shown, a negative pressure structure 4 is provided in the main body positioning groove 101 of the mounting seat 1 , and the negative pressure structure 4 is used to adsorb the patch body 501 .

[0057] By using the secondary battery patch recycling tooling of this embodiment, the patch body 501 is adsorbed by providing a negative pressure structure 4 to prevent the patch body 501 from being displaced when the release paper 6 is adhered to the adhesive layer 504 on the back of the patch body 501, and further ensure that the release paper 6 is adhered to the adhesive layer 504 on the back of the patch body 501 in the expected posture.

[0058] It can be explained that the secondary battery patch recycling tooling provided in the present application does not specifically limit the structure of the negative pressure structure 4 and can only achieve adsorption of the patch body 501 .

[0059] As one embodiment, the negative pressure structure 4 is provided with an adsorption end 401 and an access end 402. The adsorption end 401 forms a negative pressure area for adsorbing the patch body 501, and the access end 402 is used for connecting an external negative pressure pump. Specifically, the adsorption end 401 of the negative pressure structure 4 is arranged in the body positioning groove 101, and the access end 402 of the negative pressure structure 4 is arranged outside the body positioning groove 101, and the access end 402 of the negative pressure structure 4 is connected to the adsorption end 401 of the negative pressure structure 4.

[0062] like Figure 1 and Figure 2 As shown, an anti-foolproofing protrusion 103 is also provided in the main body positioning groove 101 of the mounting seat 1, and one end of the anti-foolproofing protrusion 103 arranged along the height direction is installed on the bottom of the main body positioning groove 101, and the other end of the anti-foolproofing protrusion 103 arranged along the height direction extends in a direction away from the bottom of the main body positioning groove 101, and the anti-foolproofing protrusion 103 is used to be inserted into the anti-foolproofing groove 502 of the patch 5.

The anti-foolproofing protrusion 103 can play a guiding role, ensuring that the patch body 501 is placed in the main body mounting groove in a normal posture, thereby improving the subsequent bonding quality.

[0064] like Figure 1 and Figure 2 As shown, a positioning protrusion 104 is also provided in the main body positioning groove 101 of the mounting base 1, and one end of the positioning protrusion 104 arranged along the height direction is installed on the bottom of the main body positioning groove 101, and the other end of the positioning protrusion 104 arranged along the height direction extends in a direction away from the bottom of the main body positioning groove 101, and the positioning protrusion 104 is used to be inserted into the pole hole 503 of the patch 5.

[0065] By utilizing the secondary battery patch recycling tooling of this embodiment, one end of the positioning protrusion 104 set in the height direction is installed on the bottom of the main body positioning groove 101, and the other end of the positioning protrusion 104 set in the height direction extends in a direction away from the bottom of the main body positioning groove 101. During the process of the positioning protrusion 104 being inserted into the pole hole 503, the positioning protrusion 104 can play a guiding role, ensuring that the patch body 501 is placed in the main body installation groove in a normal posture, thereby improving the subsequent bonding quality.

[0066] like Figure 1 and Figure 2 As shown, one side of the mounting seat 1 is provided with a film taking slot 105 along the height direction, one side of the film taking slot 105 extends toward the main body positioning slot 101, and the side is located inside the main body positioning slot 101 so that the film taking slot 105 is connected with the main body positioning slot 101.
