Description

Technical Field

[0001] This application relates to the technical field of electrode terminal packaging, and particularly to a packaging assembly integrating electrode terminals and a manufacturing method thereof. Background Art

[0002] In the packaging structure of a battery or a power module, the optical cover plate and the electrode terminals are key components for realizing external circuit connection. The optical cover plate usually serves as the sealing structure at the top of the battery, having good sealing performance and insulation performance; while the positive electrode terminal and the negative electrode terminal respectively serve as the positive and negative interfaces for current output, and are arranged on the optical cover plate so as to facilitate the installation of the entire power supply mechanism to an external device and realize electrical connection. Through reasonable structural design, the connection between the optical cover plate and the terminal not only needs to ensure the stability of electrical conduction, but also must have sufficient mechanical strength and environmental adaptability to ensure the safe and reliable operation of the power supply device.

[0003] In the prior art, in order to achieve the stable installation of the terminal on the optical cover plate, a stamping and stretching method is usually adopted on the upper surface of the optical cover plate to form a fixed ring structure with a certain height and strength. The fixed ring is arranged around the terminal and cooperates with it for positioning, so as to firmly fix the positive electrode terminal and the negative electrode terminal on the optical cover plate. This structural form can simplify the assembly process, improve production efficiency, and enhance the connection stability between the terminal and the optical cover plate to a certain extent, and is widely used in the manufacturing process of various battery modules.

[0004] However, the prior art has obvious defects. Since the fixed ring is formed on the upper surface (i.e., the outer surface) of the optical cover plate, and the terminal is also directly arranged on this surface, the terminal is exposed to the external environment for a long time and is easily affected by adverse factors such as humidity, dust, and corrosive gases. Especially in a use environment with high humidity or strong corrosive atmosphere, the terminal is extremely prone to problems such as oxidation, corrosion, and even short circuit, which will affect its electrical conductivity and service life, and may even cause safety accidents in severe cases. Therefore, how to improve the installation structure of the optical cover plate and the terminal so that it can not only meet the assembly requirements, but also avoid the adverse effects of the external environment on the terminal to a certain extent has become a technical problem that urgently needs to be solved to improve the safety and reliability of the power supply device. Summary of the Invention

[0005] An embodiment of this application provides a packaging assembly integrating electrode terminals and a manufacturing method thereof to solve the technical problem that the terminals on the existing optical cover plate are easily affected by the external environment. The technical solutions are as follows:

[0006] In a first aspect, an embodiment of the present application provides a packaging assembly of an integrated electrode column, comprising: a cover body having a first surface and a second surface; a first through hole is provided on the cover body, a fixing ring is provided on the second surface, and a second through hole is provided on the fixing ring to connect with the first through hole; and a column member having a first end face and a second end face arranged opposite to each other, and the column member is mounted on the cover body in an inverted manner through the fixing ring;

[0007] The first end face is exposed on the first surface through the first through hole, and the second end face is exposed on the second surface through the second through hole.

[0008] In one embodiment, the fixed ring body is bent to form a first limiting wall and a second limiting wall; the first limiting wall is perpendicular to the second surface; the second limiting wall extends toward the center of the first limiting wall and is parallel to the second surface to form a limiting groove in the fixed ring body, and the pole piece is embedded in the limiting groove.

[0009] In one embodiment, the fixing ring body and the cover plate body are integrally formed.

[0010] In one embodiment, the pole piece includes: a first part, embedded in the limiting groove, and the second end face is arranged on an end of the first part away from the first through hole; a second part, embedded in the first through hole, the second part is connected to a side of the first part away from the second end face, the first end face is arranged on an end of the second part away from the first part, and the diameter of the second part is smaller than the diameter of the first part.

[0011] In one embodiment, an insulating layer body is disposed on the first portion, and the insulating layer body is supported between the first portion and the fixing ring body.

[0012] In one embodiment, a first tooth-shaped limiting structure is arranged along the circumference of the radial side surface of the second portion; a second groove-shaped limiting structure is arranged along the circumference of the side wall of the first through hole, and the second limiting structure is meshed with the first limiting structure.

[0013] In one embodiment, it further includes: a sealing ring, which is arranged in the limiting groove, and the sealing ring is supported between the first part and the part of the cover body located in the limiting groove.

[0014] In one embodiment, a clearance groove is opened on the cover body and located on the first surface, a first through hole is arranged in the central part of the clearance groove, and the first through hole is connected to the clearance groove; the packaging assembly of the integrated electrode pole also includes: a functional layer body, which is arranged in the clearance groove and in the matching gap between the first through hole and the second part, and the surface of the functional layer body facing away from the bottom of the clearance groove is flush with the first surface.

[0015] In a second aspect, an embodiment of the present application provides a manufacturing method for a packaging assembly integrated with an electrode terminal post. The method includes: forming a first through hole in a cover plate body by means of a stamping process, and dividing the opposite surfaces of the cover plate body into a first surface and a second surface;

[0016] forming a fixing ring body perpendicular to the cover plate body on the second surface by means of a stretching process, so as to form a limiting groove by enclosing the fixing ring body and a part of the cover plate body located within the fixing ring body. The bottom of the limiting groove communicates with the first through hole, and the notch of the limiting groove is a second through hole;

[0017] The terminal post member includes a first part and a second part with a diameter smaller than that of the first part. An insulating layer body is injection-molded on the radial side surface of the first part and the second end surface facing away from the second part;

[0018] Place a sealing ring in the limiting groove, and invert the terminal post member in the limiting groove, so that the sealing ring is supported between the first part and a part of the cover plate body located within the fixing ring body. The first end surface of the second part facing away from the first part is exposed on the first surface through the first through hole. Subsequently, bend the fixing ring body inward to limit and configure the terminal post member in the limiting groove, so that the insulating layer body is supported between the first part and the fixing ring body.

[0019] In an implementation manner, it further includes: during the process of forming the first through hole by the stamping process, a relief groove located on the first surface is formed around the first through hole;

[0020] An functional layer body is injection-molded in the relief groove and in the fitting clearance between the first part and the first through hole. The surface of the functional layer body facing away from the bottom of the relief groove is flush with the first surface.

[0021] Compared with the prior art, in the above-mentioned technical solution, the integrated electrode terminal packaging assembly and its manufacturing method proposed, by installing the terminal component in the fixed ring body of the cover plate body in a flip-chip manner, and making both ends of the terminal component expose on the first surface and the second surface of the cover plate body respectively. A fixed ring body with a closed-loop structure is arranged on the second surface (i.e., the inner surface) of the cover plate body, and the terminal component is embedded therein for flip-chip fixation, so that the main structure of the terminal component is covered inside the cover plate. Compared with the traditional method of setting the fixed ring on the outer surface, this solution significantly reduces the area where the terminal is directly exposed to the external environment, thereby effectively isolating the erosion of adverse factors such as humidity and corrosive gases on the terminal, and prolonging the service life of the terminal. The terminal component is firmly connected to the cover plate body through the fixed ring body. At the same time, the first end face exposes on the first surface (outer side) of the cover plate body through the first through hole for connection with the external circuit; while the second end face exposes on the second surface through the second through hole, which is convenient for connection with the internal circuit of the power supply mechanism. This design method of double-end face exposure realizes the compactness and functional integration of the terminal installation structure on the premise of ensuring the reliability of electrical connection, improving the overall assembly efficiency and space utilization rate. Since the fixed ring body is located inside the cover plate body, the terminal component will not protrude too much from the outer surface of the cover plate after installation, further reducing the possibility of the terminal being mechanically collided, dirt accumulating, and being eroded by the environment. This structural design not only improves the protection level of the product, but also helps to enhance the overall sealing performance and insulation performance of the battery module or power supply system, providing a strong guarantee for the safe operation of the equipment under harsh working conditions.

[0022] In summary, the present application provides an integrated electrode terminal packaging assembly and its manufacturing method with reasonable structure, strong sealing performance, and good environmental adaptability, which overcomes the defect that the terminal in the prior art is vulnerable to the influence of the external environment, has good application prospects, and is particularly suitable for fields such as battery packaging with high reliability requirements, power battery systems for new energy vehicles, and energy storage devices.

[0043] In the following text, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the accompanying drawings and the description are considered to be exemplary in nature rather than restrictive.

[0044] First Embodiment

[0045] Referring to Figures 1 to 7 As shown, in an embodiment of the present application, an integrated electrode terminal packaging assembly is proposed. The integrated electrode terminal packaging assembly may include: a cover plate body 1, having a first surface 101 and a second surface 102; a first through hole 10 is provided on the cover plate body 1, and a fixing ring body 11 is provided on the second surface 102, and the fixing ring body 11 has a second through hole 110 that is docked with the first through hole 10; and, a terminal member 2, having a first end face 202 and a second end face 201 arranged opposite to each other, and the terminal member 2 is installed on the cover plate body 1 in an inverted manner through the fixing ring body 11;

[0046] Wherein, the first end face 202 is exposed on the first surface 101 through the first through hole 10, and the second end face 201 is exposed on the second surface 102 through the second through hole 110.

[0047] Specifically, in the technical solution adopted in the present application, the cover plate body 1 can be selected as a light cover plate, having an upper surface and a lower surface. In the present application, the upper surface of the light cover plate is defined as the first surface 101, and the lower surface is defined as the second surface 102. The terminal member 2 is disposed on the cover plate body 1, and the first end face 202 and the second end face 201 opposite to each other on the terminal member 2 are exposed on the cover plate body 1. A first through hole 10 is provided on the cover plate body 1, and the technical key point of the present application is that a fixing ring body 11 in a closed-loop structure is provided on the second surface 102. The side of the fixing ring body 11 facing away from the second surface 102 has a second through hole 110, and the second through hole 110 corresponds to the first through hole 10 so that the second through hole 110 can be docked and communicated with the first through hole 10. After the terminal member 2 is disposed in the fixing ring body 11 in an inverted manner, the terminal member 2 is installed on the cover plate body 1 through the fixing ring body 11, so that the first end face 202 is exposed on the first surface 101 through the first through hole 10, and the second end face 201 is exposed on the second surface 102 through the second through hole 110. Since the fixing ring body 11 is located inside the cover plate body 1, only one end face of the terminal member, that is, the first end face 202, is exposed on the first surface 101 of the cover plate body 1, thereby avoiding direct erosion of the sealing structure by the external environment, such as humidity and corrosive gases.

[0048] Furthermore, referring to Figure 6As shown, in some embodiments, the fixed ring body 11 is bent to form a first limiting wall 111 and a second limiting wall 112; the first limiting wall 111 is perpendicular to the second surface 102; the second limiting wall 112 extends toward the center of the first limiting wall 111 and is parallel to the second surface 102 to form a limiting groove 113 in the fixed ring body 11, and the pole member 2 is embedded in the limiting groove 113.

[0049] Specifically, in the technical solution adopted in the present application, in order to achieve the limit installation of the pole piece 2 in the fixed ring body 11, the fixed ring body 11 is bent to form a first limit wall 111 and a second limit wall 112. The first limit wall 111 is perpendicular to the second surface 102 and is used to wrap around the radial side of the pole piece 2, while the second limit wall 112 is bent in the circular direction of the first limit wall 111, that is, the second limit wall 112 is bent toward the inner side of the first limit wall 111 and is parallel to the second surface 102. The second limit wall 112 is used to abut against the second end face 201 of the pole piece 2, and a part of the second end face 201 is exposed through the second through hole 110, that is, the above-mentioned second through hole 110, thereby forming a limit groove 113 in the fixed ring body 11, so that the pole piece 2 can be embedded in the limit groove 113.

[0050] Further, see Figures 1 to 5 As shown, in some embodiments, the fixing ring body 11 and the cover body 1 are integrally formed.

[0051] Specifically, in the technical solution adopted in the present application, the cover body 1 can use a stretching process to form a fixed ring body 11 on the second surface 102, and the fixed ring body 11 is formed into a first limiting wall 111 and a second limiting wall 112 with an angle of 90° through a rotary riveting and bending process, so that the fixed ring body 11 and the cover body 1 are integrally formed, effectively improving the stability of the fixed ring body 11 on the cover body 1.

[0052] Further, see Figure 3 and Figure 4 As shown, in some embodiments, the pole member 2 includes: a first part 21, embedded in the limiting groove 113, and the second end face 201 is arranged on the end of the first part 21 away from the first through hole 10; a second part 22, embedded in the first through hole 10, the second part 22 is connected to the side of the first part 21 away from the second end face 201, the first end face 202 is arranged on the end of the second part 22 away from the first part 21, and the diameter of the second part 22 is smaller than the diameter of the first part 21.

[0053] Specifically, in the technical solution adopted in this application, since the diameter of the first part 21 is larger than that of the second part 22, the first part 21 can be embedded in the limiting groove 113 so that the first part 21 can be fixedly installed in the limiting groove 113. The second part 22 is then embedded in the first through hole 10. The first end face 202 is located on the side of the second part 22 away from the first part 21, and the second end face 201 is located on the side of the first part 21 away from the second part 22, so as to realize that the first end face 202 is exposed on the first surface 101 through the first through hole 10, and the second end face 201 is exposed on the second through hole 110 of the fixing ring body 11 through the second through hole 110, which is equivalent to the second end face 201 being exposed on the second surface 102, facilitating the electrical connection between the power supply device and the electrical device through the pole piece 2.

[0054] Further, referring to Figure 7 As shown, in some embodiments, an insulating layer 23 is provided on the first part 21, and the insulating layer 23 is supported between the first part 21 and the fixing ring body 11.

[0055] Specifically, in the technical solution adopted in this application, the insulating layer 23 can be made of liquid crystal polymer material - LCP. The insulating layer 23 is injection-molded on the radial side surface of the first part 21 and part of the second end face 201. Specifically, the insulating layer 23 is arranged between the first part 21 and the fixing ring body 11 to play an insulating role. And because the material of the insulating layer 23 has a certain rigid strength, it can also play a supporting role between the first part 21 and the fixing ring body 11, making the shape more regular and the riveting size more stable when the fixing ring body 11 undergoes the spin riveting process.

[0056] Further, referring to Figure 1 and Figure 3 As shown, in some embodiments, a toothed first limiting structure 221 is arranged along the circumferential direction on the radial side surface of the second part 22; a groove-shaped second limiting structure 12 is arranged along the circumferential direction on the side wall of the first through hole 10, and the second limiting structure 12 meshes with the first limiting structure 221.

[0057] Specifically, in the technical solution adopted in this application, after the second limiting structure 12 meshes with the first limiting structure 221, it can increase the torque of the pole piece 2 in the cover plate body 1, effectively preventing the pole piece 2 from rotating randomly in the cover plate body 1 and making the pole piece 2 installed in the cover plate body 1 more stable.

[0058] Further, referring to Figures 5 to 7 As shown, in some embodiments, it further includes: a sealing ring 3, disposed in the limiting groove 113, and the sealing ring 3 is supported between the first part 21 and a part of the cover plate body 1 located in the limiting groove 113.

[0059] Specifically, in the technical solution adopted in this application, in order to achieve encapsulation within the fixed ring body 11, a sealing ring 3 is disposed within the fixed ring body 11, located in the limiting groove 113. Specifically, before installing the pole piece 2 in the limiting groove 113, the sealing ring 3 is placed in the limiting groove 113 in advance. The sealing ring 3 is supported between the surface of the first part 21 close to the second part 22 and a part of the cover plate body 1 located within the limiting groove 113. When the second limiting part is bent and abuts against the second end face 201, it can drive the first part 21 to squeeze the sealing ring 3, causing the sealing ring 3 to deform within the limiting groove 113, thereby achieving the effect of encapsulating the pole piece 2 within the fixed ring body 11.

[0060] Further, referring to Figures 5 to 7 As shown, in some embodiments, a relief groove 13 is formed on the first surface 101 of the cover plate body 1. The first through hole 10 is disposed at the center of the relief groove 13 and is in communication with the relief groove 13. The encapsulation assembly of the integrated electrode pole proposed in this application further includes: a functional layer body 4, disposed in the relief groove 13 and in the mating gap between the first through hole 10 and the second part 22. The surface of the functional layer body 4 facing away from the bottom of the relief groove 13 is flush with the first surface.

[0061] Specifically, in the technical solution adopted in this application, in order to enable the pole piece 2 to play its due role on the cover plate body 1, a functional layer body 4 is further covered on the cover plate body 1. The functional layer body 4 can be made of polyphenylene sulfide material - PPS and is used to play an insulating or conductive role. In one embodiment, the functional layer body 4 can be injection-molded on the first surface 101 of the cover plate body 1 and in the mating gap between the second part 22 of the pole piece 2 and the first through hole 10 to play an insulating role. In the preferred embodiment of this application, in order to make the first surface 101 injection-molded with the functional layer body 4 have a certain flatness, a relief groove 13 for accommodating a part of the functional layer body 4 is provided on the cover plate body 1. The relief groove 13 is located on the first surface 101 around the first through hole 10. During injection molding, the functional layer body 4 with a certain fluidity can be injection-molded into the relief groove 13, and a part of the functional layer body 4 flows into the first through hole 10 through the relief groove 13. When the relief groove 13 is filled, the first surface 101 has a certain flatness, which is convenient for pasting an insulating film on the first surface 101.

[0062] Second Embodiment

[0063] In the embodiments of this application, a manufacturing method of an encapsulation assembly of an integrated electrode pole is further proposed. The manufacturing method of the encapsulation assembly of the integrated electrode pole may include the following steps:

[0064] Adopt a stamping process to form the first through hole 10 on the cover plate body 1, and divide the opposite surfaces of the cover plate body 1 into a first surface 101 and a second surface 102;

[0065] A fixing ring body 11 perpendicular to the cover plate body 1 is formed on the second surface 102 by means of a stretching process, so that a limiting groove 113 is formed by enclosing the fixing ring body 11 and a part of the cover plate body 1 located within the fixing ring body 11. The bottom of the limiting groove 113 communicates with the first through hole 10, and the notch of the limiting groove 113 is the second through hole 110;

[0066] The pole piece 2 includes a first part 21 and a second part 22 with a diameter smaller than that of the first part 21. An insulating layer body 23 is injection-molded on the radial side surface of the first part 21 and the second end surface 201 facing away from the second part 22;

[0067] A sealing ring 3 is placed in the limiting groove 113, and the pole piece 2 is inverted in the limiting groove 113, so that the sealing ring 3 is supported between the first part 21 and a part of the cover plate body 1 located within the fixing ring body 11. The first end surface 202 of the second part 22 facing away from the first part 21 is exposed on the first surface 101 through the first through hole 10. Subsequently, the fixing ring body 11 is bent inward to limit and arrange the pole piece 2 in the limiting groove 113, so that the insulating layer body 23 is supported between the pole piece 2 and the fixing ring body 11.

[0068] Refer to Figure 8 As shown, specifically, in the technical solution adopted in this application, after the fixing ring body 11 is bent by means of a spin riveting process, the cover plate body 1 configured with the pole piece 2 is placed in a two-color injection molding machine 5 to simultaneously injection-mold the functional layer body 4 on the positive and negative pole pieces on the cover plate. The functional layer body 4 injection-molded on the positive pole piece on the cover plate body 1 is conductive, while the functional layer body 4 injection-molded on the positive pole piece is insulating, thereby completing the manufacturing method of the integrated electrode pole piece package assembly, without performing a welding process or other processes that can generate high temperature on the cover plate body 1, effectively avoiding the secondary crystallization of the functional layer body 4 due to high temperature, and avoiding unnecessary influence on the resistance performance of the positive pole, the insulation performance of the negative pole, and the anti-corrosion performance of the battery.

[0069] Further, in some embodiments, it further includes: during the process of forming the first through hole 10 by means of a stamping process, a relief groove 13 located on the first surface 101 is formed around the first through hole 10;

[0070] The functional layer body 4 is injection-molded in the relief groove 13 and in the fitting gap between the first part 21 and the first through hole 10. The surface of the functional layer body 4 facing away from the bottom of the relief groove 13 is flush with the first surface 101.
