Abstract
Description
Technical Field
[0001] The utility model relates to a tool for regularizing inner and outer nickel rings, in particular to a device for regularizing inner and outer nickel rings of a TCB component. Background Art
[0002] The main internal structure of the sodium salt battery cell includes TCB components, thin gaskets, ceramic tubes, current collector components and sealing pins. It is an important component of the sodium salt battery. Whether its assembly is qualified or not plays a key role in battery performance.
[0003] The typical assembly sequence for sodium-salt batteries is as follows: first, the TCB assembly and ceramic tube are sintered together. After the ceramic tube assembly is welded to the top bridge, it is inserted into the steel casing, then welded to the current collector assembly, and finally sealed with sealing pins. During assembly, the inner and outer nickel rings of the TCB assembly are welded to the current collector assembly and top bridge, respectively. The size and shape of the inner and outer nickel rings directly affect the assembly and welding results, thereby affecting the overall sealing of the battery cell. Poor sealing can directly lead to battery cell failure.
[0004] Due to reasons such as supplier processes, transportation collisions, and normal dimensional tolerances, when the TCB components arrive at the corresponding assembly station, there may be some problems with the inner and outer nickel rings during assembly. At this time, a special regularization tool is required to regularize the inner and outer nickel rings to meet the corresponding requirements.
[0005] The principle of the inner and outer nickel ring regularization tooling in the existing technology is to support or compress the inner and outer nickel rings through a shaping head so that the size and shape of the inner and outer nickel rings meet the requirements. However, it still has the following disadvantages: the inner and outer nickel rings are shaped in steps using two tools, which is inefficient; there is no power-assisting mechanism, so a large force is required when regularizing the inner and outer nickel rings; after the shaping is completed, due to the tight fit and friction between the shaping head and the inner and outer nickel rings, it is relatively laborious and inconvenient to separate the inner and outer nickel rings from the shaping head. Utility Model Content
[0006] In view of the deficiencies in the prior art, the utility model provides a device for regularizing the inner and outer nickel rings of TCB assemblies, which solves the problems of low efficiency, large force required and laborious separation of the existing inner and outer nickel ring regularization tooling.

[0008] The auxiliary disengagement block includes an upper cylinder and a lower rectangular body, a mounting ear is provided on the side of the cylinder, the mounting ear is fixed to the side of the support frame, the limiting hole vertically penetrates the cylinder, and the accommodating cavity vertically penetrates the rectangular body.
[0009] The transverse cross-section of the rectangular body is a square, and the side length of the square is greater than the diameter of the cylinder.
[0010] The movable rod includes a connecting portion and a rod portion, the connecting portion is movably connected to the pressure rod, a spring is sleeved on the outer periphery of the rod portion, and the rod portion passes through the limiting hole.
[0011] The pressure rod is provided with a notch at a position close to the mounting plate, and the movable rod is connected to the pressure rod via a first pin shaft penetrating the notch.
[0012] The mounting plate is connected to the pressure rod via a second pin shaft.
[0013] The positive hole head is threadedly connected to the movable rod.
[0014] The positive hole head includes a shaping portion, a cross section of the shaping portion is a trapezoid, and the trapezoid includes long sides and short sides that are parallel to each other.
[0015] The inner diameter of the long side is the tolerance center value of the nickel ring size inside the TCB assembly; the outer diameter of the long side is the tolerance center value of the nickel ring size outside the TCB assembly.
[0016] Two wings are provided at the bottom end of the support frame, and the wings are fixed on the plane through a first fixing member.
[0017] From the above scheme, it can be seen that the advantages of the present invention are:

[0080] The utility model provides a device for regularizing the inner and outer nickel rings of a TCB assembly, which can be used for shaping the inner and outer nickel rings inside a sodium salt battery. The device is applied in the battery cell assembly process until the welding of the inner nickel ring and the current collector assembly is completed. For example, the device is used to regularize the size and shape of the inner and outer nickel rings. The functional requirement is to regularize the size and shape of the inner and outer nickel rings, prevent poor fitting and welding caused by poor size and shape, and reduce poor overall sealing of the battery cell caused by poor welding.
[0081] Figure 1 This is a stereoscopic diagram of a device 1 for regularizing the inner and outer nickel rings of a TCB assembly provided in one embodiment of the present invention. The device 1 for regularizing the inner and outer nickel rings of a TCB assembly includes a base 10, a support frame 11, a mounting plate 12, a pressure rod 13, a movable rod 14, an auxiliary disengagement block 15 and a positive hole head 16.
[0082] Specifically, base 10 is a rectangular structure made of a common steel material, such as 304 stainless steel. It has a rectangular flat surface 100. Base 10 primarily provides structural support, allowing the entire device 1 for aligning the inner and outer nickel rings of a TCB assembly to be placed stably on the ground or other platform. A support frame 11 is vertically mounted to the left side of flat surface 100. It is made of a common steel material, such as 304 stainless steel. Specifically, two wings 110 are provided at the bottom end of support frame 11. Wings 110 are removably mounted to the left side of flat surface 100 via first fixing members 17, such as bolts. Mounting plate 12 is removably mounted to the top of support frame 11 via second fixing members 18, such as bolts.
[0083] One end 130 of the pressure rod 13 is movably connected to the mounting plate 12. In this embodiment, the one end 130 of the pressure rod 13 is connected to the mounting plate 12 via the second pin 19, but the present invention is not limited thereto. A slot 132 is formed near the mounting plate 12 on the pressure rod 13, and the movable rod 14 is connected to the pressure rod 13 via the first pin 20 that passes through the slot 132. Figure 2As shown, the pressure rod 13 has a tapered handle that tapers from one end 130 to the other end 131. Generally, a longer pressure rod 13 reduces effort, but considering space requirements and flexibility, the applied force arm L1 is generally designed to be approximately four times the pressure arm L2. For example, if the total length of the pressure rod 13 is 230 mm, the applied force arm L1 is 211.50 ± 2 mm, and the pressure arm L2 is 52.5 mm.
[0084] like Figure 3 As shown, the movable rod 14 includes a connecting portion 140 and a rod portion 141. The connecting portion 140 defines a through hole 1400. The first pin 20 passes through the through hole 1400 and the notch 132 to connect the connecting portion 140 and the pressure rod 13. Preferably, the through hole 1400 is circular and the notch 132 is elongated. In this way, when the movable rod 14 moves up and down, the elongated notch 132 provides space for the first pin 20 to move.
[0085] like Figure 1 and Figure 3 As shown, the auxiliary disengagement block 15 includes an upper cylindrical body 150 and a lower rectangular body 151. A vertically extending limiting hole 1500 is provided inside the cylindrical body 150. The rod portion 141 of the movable rod 14 passes through the limiting hole 1500 and is connected to the positive hole head 16. A mounting ear 152 is provided on the side of the cylindrical body 150. The auxiliary disengagement block 15 is fixed to the side of the support frame 11 through the mounting ear 152. Figure 3 and Figure 4 As shown, a receiving cavity 1510 is provided in the rectangular body 151 for receiving the positive hole head 16. The transverse cross-section of the rectangular body 151 is a square, and the side length of the square is greater than the diameter of the cylindrical body 150. In other embodiments, the lower rectangular body 151 can also be replaced by a cylindrical body.
[0086] like Figure 3 As shown, a spring 21 is sleeved around the outer periphery of the rod portion 141, and a spring hole 1501 is vertically opened inside the cylindrical body 150. The spring hole 1501 is connected to the limiting hole 1500. The diameter of the spring hole 1501 is larger than the diameter of the limiting hole 1500, and the length of the spring hole 1501 is shorter than the length of the limiting hole 1500. The spring 21 is accommodated in the spring hole 1501, with one end of the spring 21 abutting the connecting portion 140 and the other end abutting the bottom end surface 1501a of the spring hole 1501. During shaping, the pressure rod 13 is forced to move downward, driving the movable rod 14 to move downward under the restriction of the limiting hole 1500. The spring 21 is compressed against the bottom end surface 1501a of the spring hole 1501. After the shaping is completed, the pressure rod 13 is released, and the spring 21 resets and drives the movable rod 14 to move upward, returning the movable rod 14 to its original position. In other embodiments, the spring 21 can also be installed at the opening 1401 inside the connecting portion 140.
[0087] In other embodiments, the movable rod 14 and the pressure rod 13 may also be connected by gears. The pressure rod 13 is provided with a gear, and the movable rod 14 is provided with a rack. The rack moves up and down by rotating the gear.
[0088] like Figure 6 As shown, the positive hole head 16 is movably connected to the rod 141, such as a threaded connection, to facilitate replacement of the positive hole head 16. Specifically, the rod 141 includes a body 1410 and a head 1411, the diameter of the head 1411 is smaller than the diameter of the body 1410, and the head 1411 is threadedly connected to the positive hole head 16.
[0089] like Figure 5 and Figure 6 As shown, the positive hole head 16 includes a shaping portion 160 and a threaded hole 161. The cross-section of the shaping portion 160 is a trapezoid, and the trapezoid includes parallel long sides 1600 and short sides 1601. The inner and outer diameter dimensions of the long side 1600 are designed to be the middle values of the required dimensions of the inner and outer nickel rings of the TCB assembly 3. For example, the first inner diameter d1 of the long side 1600 is the tolerance center value of the specified size of the inner nickel ring 30 of the TCB assembly 3 (referring to the middle value of the upper and lower limits of the size tolerance range); the first outer diameter d2 of the long side 1600 is the tolerance center value of the specified size of the outer nickel ring 31 of the TCB assembly 3. The first inner diameter d1 of the long side 1600 is smaller than the second inner diameter d3 of the short side 1601, and the first outer diameter d2 of the long side 1600 is larger than the second outer diameter d4 of the short side 1601, that is, d1 <d3<d4<d2。杆部141的头部1411与正孔头16的螺纹孔161螺纹连接,且头部1411的长度短于螺纹孔161的深度。
[0090] like Figure 7 、 Figure 8 As shown, during shaping, the TCB assembly 3 (including the inner and outer nickel rings and other parts) is placed on the right side of the plane 100 of the base 10, aligned with the positive hole head 16, and the pressure rod 13 is forced to move downward, driving the movable rod 14 to move downward along the limiting hole 1500. The spring 21 is compressed, and the rod portion 141 of the movable rod 14 drives the positive hole head 16 to move downward. The short side 1601 of the shaping portion 160 enters between the inner nickel ring 30 and the outer nickel ring 31, and the long side 1600 moves downward to squeeze the inner nickel ring 30 and the outer nickel ring 31. The pressure acts on the plane 100 of the base 10 through the TCB assembly 3, thereby achieving regularization of the shapes and sizes of the inner and outer nickel rings.
[0091] like Figure 9 As shown, after the shaping is completed, the pressure rod 13 is released, or the pressure rod 13 is pulled upward, the spring 21 is reset to drive the movable rod 14 to move upward, the positive hole head 16 is hidden in the accommodating cavity 1510, and the edge 310 of the outer nickel ring 31 is supported by the rectangular body 151 under the auxiliary separation block 15, so that the positive hole head 16 is separated from the inner nickel ring 30 and the outer nickel ring 31.
[0092] In summary, the present invention utilizes a lever-assisted structure to reduce the force required during the shaping process, thereby overcoming the laborious nature of the conventional shaping tooling process. Furthermore, the inner and outer nickel rings are shaped simultaneously, eliminating the need for separate shaping steps, thus saving time. Finally, the auxiliary disengagement block 15 of the device 1 for aligning the inner and outer nickel rings of a TCB assembly automatically disengages the main hole head 16 from the TCB assembly 3 during the ascending process. The entire device 1 for aligning the inner and outer nickel rings of a TCB assembly is compact and simple in structure, easy to operate, and convenient for maintenance and adjustment.
[0093] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms under the guidance of the present invention, all of which fall within the scope of protection of the present invention.
