Description

Technical Field

[0001] The utility model relates to the technical field of battery production, in particular to a beaker for welding battery terminals. Background Art

[0002] Terminal welding is a crucial process in the production of batteries. This process mainly uses hot melt technology to ensure a solid connection between the internal pole of the battery and the external terminal. In this process, the terminal welding beaker, as an indispensable auxiliary tool, plays a dual role: first, it effectively prevents the flame from accidentally contacting the area outside the terminal welding surface through physical isolation, ensuring the safety and accuracy of the welding process; second, the cavity design of the beaker helps the welding surface to be better formed, improving the quality and efficiency of welding.

[0003] However, there are some obvious limitations in the design and application of current terminal welding beakers. In order to ensure that the lead liquid does not flow out during welding, the beaker needs to fit tightly on the step of the terminal. But traditional beakers are mostly made of cast iron, which faces high temperature challenges during welding. When the welding flame temperature reaches 1200°C, the cast iron beaker will heat up rapidly and transfer a large amount of heat to the plastic boss under the battery terminal through heat conduction. Plastic easily melts at high temperatures to form gaps, which not only affects the structural integrity of the battery, but more seriously, the molten plastic gaps may cause acid to climb and further corrode the terminals, posing a serious threat to the overall performance and appearance quality of the battery.

[0004] Therefore, a technical solution to the above problems is needed. Utility Model Content

[0005] In order to solve the technical problems existing in the prior art, the purpose of the utility model is to provide a beaker for welding battery terminals to solve the above-mentioned technical problems.

[0006] In order to achieve the purpose, the utility model adopts the following technical solutions:

[0007] A beaker for battery terminal welding, used for assisting terminal welding in a battery, comprising:

[0008] main body;

[0009] A welding cavity is provided on the main body and can be used for at least a portion of the terminal to be inserted into for welding;

[0010] A protective cavity, disposed on the main body, into which the terminal can at least partially extend;

[0011] A cooling water channel, comprising an annular groove disposed on the main body surrounding the welding cavity for introducing cooling water to cool the welding cavity, and a water inlet hole communicating with the annular groove for the cooling water to flow in and a water outlet hole for the cooling water to flow out; and

[0012] The counterweight structure is installed on the side of the main body and is used to maintain the stability of the main body when installed on the battery.

[0013] Preferably, the main body further includes a positioning portion for positioning the terminal.

[0014] Preferably, the positioning portion is arranged at the bottom of the welding cavity and partially protrudes from the bottom surface of the main body. The inner cavity of the positioning portion is arranged to be a second conical hole whose shape is adapted to the shape of the terminal. When the main body is installed in the battery, the second conical hole can be positioned on the terminal and fit with the terminal to prevent the lead liquid from flowing out during welding.

[0015] Preferably, the annular groove is a stepped groove.

[0016] Preferably, the counterweight structure is a counterweight block detachably mounted on a side surface of the main body.

[0017] Preferably, the counterweight is made of high temperature resistant metal material.

[0019] Preferably, the main body is also provided with a mounting hole for mounting the main body.

[0020] The utility model provides a cooling water channel surrounding the welding cavity on the main body, and uses water cooling to cool the beaker, thereby preventing the beaker from heating up too quickly and preventing the plastic from melting due to the beaker being too hot during welding. Within the specified welding time, the beaker temperature is lower than the melting point of the plastic, thus solving the problem of terminal step melting caused by the beaker being too hot. A counterweight structure is also provided on the main body, so that the stability of the beaker can be maintained when the beaker is installed on the battery. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] like Figure 1 The figure is a schematic diagram of the overall structure of the developing box of the present invention.

[0034] like Figures 1 to 6 As shown, a beaker for battery terminal welding (hereinafter referred to as beaker) is provided, which can be used to assist in welding the battery 9 terminals.

[0035] like Figure 1 , Figure 2 As shown, the beaker includes a main body 1, a welding cavity 2 arranged on the main body 1, a protective cavity 3 arranged on the main body 1, and a cooling water channel 4 arranged on the main body 1. During use, the main body 1 of the beaker is installed on the battery 9 by corresponding to the terminal position of the battery 9, the welding cavity 2 is used to weld the terminal part that needs to be welded, the protective cavity 3 is used to protect the terminal part that does not need to be welded, and the cooling water channel 4 can cool the main body 1 to prevent the beaker temperature from being too high during welding, causing the plastic of the battery 9 to melt.

[0036] The main body 1 is a block structure of a roughly rectangular parallelepiped structure. Preferably, the main body 1 is made of a high temperature resistant metal material.

[0037] The welding chamber 2 is a first conical hole that passes through the middle of the main body 1. The diameter of the first conical hole gradually decreases from top to bottom. The first conical hole facilitates welding operations in the welding chamber 2 and can effectively prevent lead liquid and flame splashing during welding.

[0038] The main body 1 is provided with a roughly rectangular through hole 61 on one side of the welding cavity 2. The rectangular through hole 61 serves as a protective cavity 3. The part of the terminal that does not need protection can be accommodated in the rectangular through hole 61 or extend out of the rectangular through hole 61. The main body 1 separates it from the part of the terminal that needs welding.

[0039] In some embodiments, the beaker further includes a positioning portion 5, which can be used to position the terminal. Preferably, the positioning portion 5 is disposed at the bottom of the welding chamber 2, and partially protrudes from the bottom surface of the main body 1. The inner cavity of the positioning portion 5 is configured as a second tapered hole 51, and the diameter of the second tapered hole 51 gradually increases from top to bottom, which is adapted to the shape of the terminal, can be positioned on the terminal, and fits with the terminal during installation to prevent lead liquid from flowing out during welding.

[0040] Preferably, the second tapered hole 51 is adjacent to the first tapered hole.

[0041] The cooling water channel 4 is arranged on the bottom surface of the main body 1, and is located below the welding cavity 2 and arranged on the main body 1 around the welding cavity 2. Specifically, in the present embodiment, the cooling water channel 4 includes an annular groove 41 arranged on the bottom of the main body 1, and the annular groove 41 is arranged around the welding cavity 2. When the cooling water enters, it can flow in the annular groove 41. The annular design allows the cooling water to be closer to the welding cavity 2. The annular groove 41 with an annular design can also make the contact area between the cooling water and the welding cavity 2 larger, so that when the welding cavity 2 is cooled, the cooling effect is better, and it can prevent the melting of the plastic when the welding cavity 2 is in direct contact with the battery 9 shell.

[0042] The cooling water channel 4 also includes a water inlet hole 42 and a water outlet hole 43 on the side of the main body 1, which can be used to connect to the water inlet pipe and the water outlet pipe respectively for the inlet and outlet of cooling water. Preferably, the water inlet hole 42 and the water outlet hole 43 are located on the same side of the main body 1, and are both connected to the annular groove 41 for the inlet and outlet of cooling water.

[0043] In some embodiments, the annular groove 41 in the cooling water channel 4 can be closed, that is, a seal is welded at the bottom of the annular groove 41 to ensure that the cooling water does not flow out during circulation. Preferably, a closing plate can be welded at the bottom of the annular groove 41.

[0044] Alternatively, in some other embodiments, the annular groove 41 may not be closed, and when the beaker is installed on the battery 9, a cavity for cooling water to flow is formed between the annular groove 41 and the battery 9 shell.

[0045] In some embodiments, the annular groove 41 is provided with a stepped groove. Specifically, the annular groove 41 has a large diameter portion near the bottom of the main body 1 and a small diameter portion away from the bottom of the main body 1. By providing the stepped groove, the steps of the annular groove 41 form a reserved welding position. The annular groove 41 is welded at the bottom to form a closed cooling water circulation space, which solves the problem of the difficulty of processing the existing annular groove 41 by only two holes (water inlet hole 42 and water outlet hole 43). The beaker is processed by first processing the annular groove 41 and then performing repair welding on the annular groove 41, which makes the beaker simple to manufacture.

[0046] The beaker further comprises a counterweight structure 6. Preferably, the counterweight structure 6 is a counterweight block arranged on one side of the main body 1, for example, a counterweight block made of a metal material, which can prevent high temperature melting while performing counterweighting.

[0047] In some embodiments, the counterweight structure 6 is located on the other side of the main body 1 opposite to the water inlet hole 42 and the water outlet hole 43 .

[0048] like Figure 3 As shown, in some embodiments, the counterweight structure 6 can be detachably mounted on the main body 1. For example, in this embodiment, the main body 1 is provided with two screw holes 11 on one side, and the configuration block is provided with two through holes 61 penetrating therethrough, and two bolts 7 are passed through the through holes 61 and then screwed into the screw holes 11, and the head diameter of the bolt 7 is larger than the diameter of the through hole 61. When the bolt 7 is tightened, it can be fixed on the main body 1, thereby fixing the counterweight block on one side of the main body 1.

[0049] like Figure 4 As shown, in some embodiments, the main body 1 is further provided with a mounting hole 8 for mounting the beaker on the device. For example, the mounting hole 8 is provided on the main body 1, and the beaker can be mounted on the welding head of the welding device through the mounting hole 8. During use, the beaker descends to the terminal position of the battery 9 as the welding head descends, and welding is performed, which can realize automatic operation.

[0050] Preferably, the mounting hole 8 is provided on the top of the main body 1 .

[0051] Preferably, a plurality of mounting holes 8 can be arranged in an array on the bottom of the main body 1, and the beaker can be fixed through any one or more mounting holes 8 as needed, which is convenient for installation and adjustment. Figure 4 In this embodiment, seven mounting holes 8 are provided at the bottom of the main body 1 along the width direction of the main body 1 .

[0052] The use process of the utility model beaker is as follows:

[0053] refer to Figure 5 , Figure 6The terminal in the battery 9 generally includes two parts, namely a cylindrical terminal part 92 and a right-angle terminal part 91 for electrical connection with the inside of the battery 9. A pole 93 is arranged inside the battery 9, and the pole 93 extends from the inside of the battery 9 to the cylindrical terminal part 92 in the terminal.

[0054] When in use, align the positioning part 5 in the beaker with the cylindrical terminal part 92, align the protective cavity 3 with the right-angle terminal part 91, and install the main body 1 on the battery 9 housing. When the beaker is installed in place, the cylindrical terminal part 92 of the terminal of the battery 9 extends into the welding cavity 2 through the positioning part 5, and the right-angle terminal part 91 extends out of the protective cavity 3. The welding cavity 2 is welded, because the top of the pole 93 is lead, after it extends to the cylindrical terminal part 92 of the terminal, welding is the flame burning on the pole 93, melting the lead at the upper end, and forming it in the welding cavity 2 of the beaker, forming a whole with the cylindrical terminal. In this process, the beaker wraps the exposed part of the terminal inside to isolate the flame.

[0055] It is understandable that, when the beaker is mounted on the automated welding equipment through the mounting hole 8, the working principle is roughly the same as the above process, that is, the beaker is mounted on the storage battery 9 along with the welding head, and the welding head completes the welding.

[0056] The utility model provides a cooling water channel surrounding the welding cavity on the main body, and uses water cooling to cool the beaker, thereby preventing the beaker from heating up too quickly and preventing the plastic from melting due to the beaker being too hot during welding. Within the specified welding time, the beaker temperature is lower than the melting point of the plastic, thus solving the problem of terminal step melting caused by the beaker being too hot. A counterweight structure is also provided on the main body, so that the stability of the beaker can be maintained when the beaker is installed on the battery.

[0057] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
