[0030] An aerosol generating device is a machine used to generate aerosols. It typically converts liquid or solid substances into gaseous particles by heating or vibrating them, and then releases these particles into the air to form aerosols. This device can generate tiny particles of specific sizes and shapes for use in various fields. The aerosol generating device is a small cylindrical structure. During production and assembly, a mainboard structure needs to be welded to its shell. Due to its small size, the small cylindrical shell is prone to rolling during soldering, making soldering difficult. Furthermore, solder balls generated during the soldering process are difficult to remove once they fall into the shell, potentially affecting its internal structure. This solution proposes a welding fixture to address these issues affecting the production stability of the aerosol generating device.

[0031] This utility model proposes a welding fixture 100 to solve the above problems.

[0032] Please see Figures 1 to 4 In one embodiment of this utility model, a welding fixture 100 is proposed. The welding fixture 100 is mainly used in the welding operation of the production of aerosol generating devices. Aerosol generating devices are generally small cylindrical structures with corresponding grooves on their arc-shaped sidewalls to connect their internal cavities. At these grooves, the main components need to be welded to their internal structure by soldering. Traditional welding methods lack effective fixing structures. Due to the small cylindrical structure, the main structure of the aerosol generating device is prone to rolling during the soldering process, making it easy to deviate during welding and difficult to operate. Furthermore, because the main structure of the aerosol generating device is small, solder balls generated during the soldering process are difficult to remove once they fall into the main structure of the aerosol generating device. Once this happens, the welding structure of the semi-finished product needs to be disassembled, and each component needs to be disassembled to find the solder balls, which greatly reduces production efficiency and increases rework time. Therefore, in this embodiment, the above problems are solved by the welding fixture 100. It can be inferred that the welding fixture 100 disclosed in this solution is not only suitable for welding in the production of aerosol generating devices, but also applicable to similar structures with cylindrical features to be welded. Therefore, in the following description, the specific application scenario of the welding fixture 100 can be summarized as using it to clamp components with welding parts to be assembled.

[0033] The welding fixture 100 includes a base 1, a holding cover plate 2, and an anti-rotation limiting structure. The base 1 has a mounting surface 11; the holding cover plate 2 is connected to the mounting surface 11, and a receiving cavity is formed between the holding cover plate 2 and the base 1 to receive the clamping component to be installed. An exposed opening 24 communicating with the receiving cavity is formed on the holding cover plate 2, allowing the welding portion of the clamping component to be installed to be exposed outwards; the anti-rotation limiting structure is provided on the base 1 and / or the holding cover plate 2 to prevent the clamping component from rotating during installation.

[0034] Its specific structure includes two parts: a base 1 and a holding cover plate 2. The base 1 is a structural component that supports the clamping part to be installed. It has a mounting surface 11 for supporting the clamping part. After the mounting surface 11 contacts one end of the clamping cover plate, a receiving cavity corresponding to the shape of the clamping part to be installed can be formed between the two. In fact, the receiving cavity is formed by two receiving grooves 5 interlocking with each other. The two receiving grooves 5 are respectively provided on the mounting surface 11 and the holding surface 22. The holding surface 22 is an end face corresponding to the holding part and the mounting surface 11. The two receiving grooves 5 are set as arc-shaped split groove structures, each with half of the arc surface. After the holding surface 22 and the mounting surface 11 abut against each other, they together form the receiving cavity. During fixing, the clamping part to be installed is first placed in the receiving groove 5 on the base 1, and then the clamping part to be installed is limited and fixed in the receiving groove 5 by the interlocking of the base 1 and the holding cover plate 2. It is conceivable that, in addition to forming the receiving cavity by setting the split arc-shaped groove structure on the base 1 and the pressure cover plate 2, corresponding groove structures or irregular groove structures can also be set on the above two structures to achieve the above-mentioned technical effects of receiving the clamping parts. The settings can be made according to the actual situation.

[0035] The clamping component is fixed in the above manner. The clamping component is cylindrical. To prevent the clamping component from rotating around its axis in the receiving cavity, an anti-rotation limiting structure is provided on the side corresponding to the mounting surface 11 and the pressing surface 22. The anti-rotation limiting structure can be installed on any of the two structures mentioned above. It mainly abuts the clamping component by contacting it downwards, thereby preventing the clamping component from rotating in the receiving cavity. Furthermore, as mentioned above, the clamping component has a welded part. When the welded part is applied to the aerosol generating device, it is correspondingly welded to the main board component on its groove structure. After the clamping component is fixed, it is located between the base plate and the pressing cover plate 2. To facilitate welding of its welded part, an exposed opening 24 communicating with the receiving cavity is formed on the pressing cover plate 2. The welded part of the clamping component can be exposed through the exposed opening 24. At this time, welding operations can be performed at the welded part position using a relevant welding device.

[0036] When the component to be clamped is an aerosol generating device, the size of the exposed opening 24 is consistent with the size of the slot on the welding main plate component on the side wall of the aerosol generating device, such as... Figure 1 As shown, the area outside the motherboard is covered by the pressure cover plate 2. The motherboard is then soldered onto the aerosol generating device through the exposed opening 24. During this process, because the aerosol generating device is fixed in the receiving cavity by the anti-rotation limiting structure, the soldering part is stably positioned at the exposed opening 24, improving the stability of the soldering process and significantly contributing to improved soldering quality and reduced soldering defects. Furthermore, the slot for placing the motherboard in the aerosol generating device is covered by the motherboard, and the slot structures in other areas are covered by the pressure cover plate 2, not exposed. Therefore, during soldering, solder balls can be effectively prevented from splashing into the housing of the aerosol generating device, thus avoiding the need for disassembly of the semi-finished product. Therefore, this structure significantly improves the stability and convenience of the aerosol generating device during the soldering process, contributing to increased production efficiency.

[0037] An abutment portion is provided within the accommodating cavity. The abutment portion has an abutment plane for abutting against the mating plane of the clamping member to be installed to prevent rotation.

[0038] Specifically, as described above, the anti-rotation limiting structure limits and fixes the clamping part to be installed by abutting. The part of the anti-rotation limiting structure that extends into the cavity forms an abutting portion. The end of the abutting portion that contacts the clamping part to be installed is an abutting plane. The clamping part to be installed is pressed down by the abutting plane, thereby preventing it from moving inside the cavity.

[0039] The abutting part includes an abutting strip 3, the end face of which in its thickness direction abuts against the mating plane of the clamping member to be installed to prevent rotation.

[0040] Specifically, the abutting part includes an abutting strip part 3, which is configured as a plate-like structure with one plane in its thickness direction serving as the abutting plane. In order to achieve a better pressing and fixing effect, in this embodiment, the abutting strip part 3 is arranged across the receiving cavity. The pressing surface 22 of the pressing cover plate 2 is provided with two mounting grooves 23 located on both sides of the receiving cavity, and each mounting groove 23 is laterally connected to the receiving cavity. The two ends of the abutting strip part 3 are respectively disposed in the two mounting grooves 23. Specifically, the pressing surface 22 of the pressing cover plate 2 is provided with two mounting grooves 23 located on both sides of the receiving cavity, and the two mounting grooves 23 are laterally connected to the receiving cavity. The two ends of the abutting strip part 3 are respectively disposed in the two mounting grooves 23 and are fixedly installed inside the mounting grooves 23 by screws 4. With this configuration, the abutting strip 3 spans the entire receiving cavity. Its two ends are fixed, and its central plane applies force to the mating plane of the clamping component, increasing the upper limit of the downward pressure applied by the abutting strip 3 and thus providing greater downward pressure. It should be noted that when the mounting surface 11 and the holding surface 22 abut against each other, they together form the receiving cavity. To avoid affecting the attachment of the mounting surface 11 and the holding surface 22, the abutting strip 3 adopts a recessed installation method. Its upper end or the corresponding screw 4 end does not extend beyond the holding surface 22, thus not affecting the contact between the two planes.

[0041] The pressing cover plate 2 has a pressing surface 22 facing the mounting surface 11. Two receiving grooves 5 are provided on the pressing surface 22 and the mounting surface 11 respectively. The openings of the two receiving grooves 4 are arranged opposite to each other to jointly define the receiving cavity.

[0042] Specifically, to facilitate the placement and removal of the clamping component, a receiving groove 5, referred to as the first receiving groove, is provided on the base 1. One end of the first receiving groove is located within the plane of the base 1, and the other end extends through the base 1. Since the first receiving groove is a split semi-circular arc shape, after the clamping component is placed in the receiving groove 5, one end of the component protrudes above the mounting surface 11. When actually placing or removing the clamping component, it can be pushed into the first receiving groove from a horizontal end of the base 1. To remove it, the other end can be pushed to push the component out of the first receiving groove. This avoids the problem of the exposed part of the clamping component being arc-shaped, making it difficult to remove from the first receiving groove.

[0043] In addition, multiple receiving cavities are provided to accommodate multiple clamping parts to be assembled. It is conceivable that, in actual production, to improve work efficiency and avoid frequent loading of clamping parts, multiple corresponding receiving grooves 5 can be provided on the base 1 and the pressure cover plate 2, thus forming multiple receiving cavities after the two structural components are closed. This allows multiple clamping parts to be assembled to be fixed at once by the base 1 and the pressure cover plate 2, enabling continuous welding operations and avoiding frequent material loading. This improves work efficiency and convenience. Furthermore, after welding is completed, to facilitate the separation of the base 1 and the pressure cover plate 2, at least one of the base 1 and the pressure cover plate 2 extends laterally beyond the other to form an operating protrusion 25. In this embodiment, the operating part is located on one side of the pressure cover plate 2; pulling the operating protrusion 25 upwards allows for better separation of the base 1 and the pressure cover plate 2. Furthermore, a connecting groove 26 is provided on the pressure cover plate 2, which connects multiple receiving cavities. By prying the connecting groove 26, the separation of the base 1 and the pressure cover plate 2 can be facilitated, and it is possible to observe from the connecting groove 26 whether one end of multiple clamping parts to be installed is in place.

Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
