Description

Technical Field

[0001] This utility model relates to the field of spot welding machine technology, specifically to a mobile phone battery spot welding machine. Background Technology

[0002] The battery is a crucial component of a mobile phone. Disassembling and inspecting a mobile phone battery involves a small amount of destructive disassembly. During reassembly, it is sometimes necessary to weld the battery in place, specifically welding the battery output end to the battery board. This is typically done using a portable, small spot welding machine. However, existing portable spot welding machines lack auxiliary clamping and fixing structures. For example, Chinese patent CN215787406U discloses a portable spot welding machine with a built-in power supply that can operate with its own power source. The delay time and spot welding power can be adjusted via control buttons. It can charge the battery pack via a Type-C interface and charge mobile phones and digital devices via a USB interface, making it safe and convenient to use.

[0003] While portable spot welding machines are convenient to use, in practical applications, when welding the battery output end to the battery board, existing welding machines lack a fixing structure. They require additional clamps to hold the battery and battery board, or manual pressing to fix the welded parts. This reduces portability, and manual pressing can cause wobbling and misalignment during welding, presenting certain limitations. Therefore, this paper proposes a mobile phone battery spot welding machine with a clamping and fixing structure to solve these problems. Utility Model Content

[0020] The technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings. In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The present invention will be further described below with reference to the accompanying drawings.

[0023] Please refer to the following: Figures 1-4The present invention relates to a spot welding machine for mobile phone batteries, comprising: a spot welding machine body 1, an insulating plate 7 provided on one side of the upper end of the spot welding machine body 1, a limiting plate 2 provided on one side of the top of the insulating plate 7, a clamping block 3 movably connected to the side of the insulating plate 7 facing the limiting plate 2, a first spring 4 connected between the limiting plate 2 and the clamping block 3, a shaft 8 provided on one side of the top of the insulating plate 7, a movable plate 9 rotatably connected to the shaft 8, a pressure rod 10 slidably connected to the end of the movable plate 9 away from the shaft 8, a pressure plate 11 connected to the bottom end of the pressure rod 10, and a welding station 15 provided on the side of the top of the insulating plate 7 near the clamping block 3.

[0024] Combination Figure 3 and Figure 4 As shown, the clamping block 3 has an anti-slip strip 5 at its top and a trapezoidal block 6 at its bottom. The trapezoidal block 6 is slidably connected to the inside of the top of the insulating plate 7. The clamping block 3 is directly opposite the welding station 15. The battery board 16 is clamped between the clamping block 3 and the welding station 15. The battery body 14 is clamped between the pressure plate 11 and the insulating plate 7. The pressure rod 10 is located between the movable plate 9 and the pressure plate 11 and is fitted with a second spring 12. The bottom of the pressure plate 11 is provided with a rubber pad. The rubber pad helps to ensure that the pressure plate 11 will not wear the battery body 14. The top of the pressure rod 10 is connected to a pull ring 13 through a hinge. This allows the pull ring 13 to be raised and the pressure plate 11 to be pulled upwards when in use. When not in use, the pull ring 13 can be tilted down and retracted so that the protective cover 18 can be closed on the spot welding machine body 1.

[0025] The above structure realizes the clamping and fixing structure when the mobile phone battery spot welding machine welds the battery input and battery board.

[0026] The spot welding machine body 1 has a display screen 17 on one side of its upper end, and a spot welding port 19 on the side of the upper end of the spot welding machine body 1 near the display screen 17. The welding pen 23 can be connected to the spot welding port 19 to perform welding operations. The other side of the spot welding machine body 1 has a USB interface 20, and the upper end of the spot welding machine body 1 has a type-c interface 21. The control button 22 is located below the display screen 17. The spot welding circuit inside the spot welding machine body is a prior art circuit and will not be described in detail here.

[0027] The spot welding machine body 1 is hinged to one end of the insulating plate 7 with a protective cover 18. A clamping head is provided on the inner end of the protective cover 18. The pressure plate 11 has a circular structure, and the clamping block 3 is made of insulating plastic. Several anti-slip strips 5 are provided on the top of the clamping block 3. At least one first spring 4 is provided between the limiting plate 2 and the clamping block 3. Nickel sheets are connected to the welding ends of the battery small plate 16 and the battery body 14, and the battery small plate 16 and the battery body 14 are welded together by the nickel sheets. The height of the shaft 8 is less than or the same as the depth of the protective cover 18. A slot matching the clamping head is provided on one side of the top of the spot welding machine body 1, making it difficult for the protective cover 18 to open automatically after it is closed. This further improves the overall portability.

[0028] Specifically, in use, the battery plate 16, which needs to be welded to the output end of the battery body 14, can be clamped between the clamping block 3 and the welding station 15. When using the clamping block 3, simply press the anti-slip strip 5 manually to push the clamping block 3. Stopping the push allows the clamping block 3 to move towards the welding station 15 via the elastic force of the first spring 4, thus completing the clamping action. Next, align the welding end of the battery body 14 to be welded with the welding end on the battery plate 16, and then manually pull the pull ring 13 upwards. This pull ring 13 lifts the pressure rod 10, causing the pressure rod 10 to move upwards along with the pressure plate 11. Rotating the movable plate 9 positions the pressure plate 11 above the battery body 14. Stopping the pull ring 13 allows the pressure plate 11 to press against the battery body 14 under the elastic force of the second spring 12, thus limiting the position of the battery body 14 and preventing displacement of the battery body 14 and battery plate 16 during welding. After clamping and fixing, electrode connections can be made using the plug-in welding joints for welding.

[0029] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0030] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
