Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile accessory assembly, more specifically to an instrument cover anti-interference welding structure. BACKGROUND

[0002] The automobile instrument cover is an important part of the automobile interior, not only bearing the function of protecting the internal components, but also needing to match the overall design of the vehicle to ensure aesthetics and user experience. In the production process of the automobile instrument cover, the application of welding fixtures is crucial. Traditional automobile instrument cover welding processes mostly use manual welding or simple mechanical fixing methods. However, these methods have many problems, such as difficulty in ensuring welding precision, low welding efficiency, prone to welding defects, and high skill requirements for operators. In addition, during the manual welding process, the instrument cover parts are prone to deformation or damage due to collision, especially the plastic parts. In order to improve the welding quality and efficiency, welding fixtures have emerged. The main function of the welding fixture is to fix and position the parts to be welded, ensuring the accurate relative position of the parts during welding. Through precise fixture design and automatic control, the welding fixture can significantly improve the welding precision and reduce human factors. With the development of automobile manufacturing technology, advanced welding technologies such as ultrasonic welding and laser welding are gradually applied to the production of automobile instrument covers. These technologies not only improve the welding speed, but also improve the welding quality and reduce the welding deformation. For example, ultrasonic welding technology realizes the rapid melting and bonding of plastic parts through high-frequency vibration, which can complete high-precision welding in a short time. However, the existing welding fixtures use single-point welding head design, which has low welding efficiency, especially on complex workpieces with multiple welding points, which requires multiple adjustments of the welding position, increasing the welding time and cost. On the other hand, the single-point welding head is usually large and thick, which makes it prone to interference during welding, especially when welding irregular-shaped and thin-walled parts such as instrument covers. The size of the welding head limits the flexibility of the operation, and the large welding head also limits the space for welding operation, making it difficult to accurately control the welding position and affecting the welding precision. Therefore, there is still a need for an instrument cover anti-interference welding structure that can improve welding efficiency and precision. SUMMARY

[0003] The technical problem to be solved by the present application is to provide an instrument cover anti-interference welding structure. The welding structure sets up multiple welding columns corresponding to multiple welding points on the instrument cover, thereby reducing the size of the welding columns and welding heads, avoiding interference during welding, and improving welding efficiency and precision.

[0004] The application provides an instrument cover anti-interference welding structure, which comprises an operation platform and a connecting plate, the operation platform is provided with a profiling base for mounting the instrument cover, the connecting plate is installed on the operation platform in a lifting manner, the connecting plate is provided with positioning columns and welding columns, the positioning columns are lifted or lowered to clamp or release the instrument cover in cooperation with the profiling base, the welding columns are provided with welding heads, and the positioning columns and the welding columns are arranged in a plurality of sets along the circumference of the instrument cover, and the plurality of welding columns correspond to a plurality of welding points on the instrument cover.

[0005] In the technical solution, the profiling base is arranged on the operation platform, the profiling base can accurately match the shape of the instrument cover, the instrument cover can be positioned and mounted on the profiling base, the instrument cover can be quickly and labor-savingly mounted, and the instrument cover can be stably welded, the connecting plate is installed on the operation platform in a lifting manner, the connecting plate can drive the positioning columns and the welding columns to synchronously lift or lower, the positioning columns are lowered to be close to the profiling base, the positioning columns can abut against the instrument cover and press the instrument cover on the profiling base, the positioning columns are lifted to be away from the profiling base, the positioning columns can release the instrument cover, so that the instrument cover can be taken out from the profiling base, a plurality of positioning columns are arranged, so that the instrument cover can be stably fixed during welding, a plurality of welding columns are arranged, the welding heads for welding operation are arranged on each welding column, the design of the multi-point welding columns and the welding heads allows the plurality of welding points on the instrument cover to be simultaneously operated, the repeated positioning and welding time in the traditional single-point welding mode is reduced, the production efficiency is greatly improved, the size of the welding columns and the welding heads can be reduced, interference during welding is avoided, the welding columns correspond to the welding points on the instrument cover, and each welding point can be fully welded, so that the welding quality, the welding efficiency and the welding precision are improved.

[0006] As an improvement, the bottom of the welding head is in the shape of a line, and the welding head is in the shape of a flat column. In the technical solution, the flat column structure of the welding head makes the welding head more compact in space, can adapt to the welding demand of a narrow space, has a smaller contact area during welding, has higher operation flexibility in the narrow space, can easily reach the welding points of a complex structure, the line-shaped bottom allows the welding head to accurately align the welding points during welding, reduces the welding deviation caused by the mismatch of the shape of the welding head, improves the welding quality, and effectively avoids interference with other components during welding due to the small size and regular shape of the welding head, is suitable for the welding scene of a complex structure, and improves the welding efficiency.

[0007] As an improvement, the welding head is an ultrasonic welding head. In this technical solution, the ultrasonic welding head transmits mechanical energy to the welding area through high-frequency vibration (usually 20 kHz or higher), causing the material to melt and bond quickly in a local area. This energy transmission method makes the welding process highly concentrated, generating heat only in the area where the welding head contacts the workpiece, reducing the impact on the surrounding material. In the ultrasonic welding process, the contact time between the welding head and the instrument cover is extremely short. This non-contact welding method reduces physical interference between the welding head and the workpiece, while avoiding thermal damage to the workpiece caused by high temperatures. The compact design and high-frequency vibration of the ultrasonic welding head allow it to perform welding operations in narrow spaces without interfering with other components or structures, ensuring the stability and consistency of the welding process.

[0008] As an improvement, the connecting plate is provided with a heating rod, which is connected to the welding column through the connecting plate, and the heating rod conducts heat to the welding head through the welding column. In this technical solution, the heating rod is connected to the welding column, and heat is conducted through the welding column, which can more efficiently transfer heat than directly heating the welding head, reducing heat loss during transmission, and achieving a close combination of heating function and welding operation, so that heat can be accurately transferred to the welding area. The structure of the heating rod is relatively simple, mainly composed of a resistance wire, an insulating layer and a metal shell, easy to manufacture and maintain. By conducting heat through the welding column, heat can be concentrated at the welding point, reducing the thermal impact on the surrounding material and helping to reduce welding deformation. It is suitable for welding thin plates such as instrument covers, and the design of the heating rod eliminates the heating tube component in the welding column, making the welding column smaller and less likely to interfere with other components during welding.

[0009] As an improvement, the connecting plate is an aluminum plate. In this technical solution, an aluminum plate is selected as the connecting plate. Aluminum plate has good thermal conductivity and electrical conductivity, with thermal conductivity about 3 times that of iron. The aluminum plate can quickly conduct heat during welding, reducing preheating time and heat loss during welding, thereby improving welding efficiency. On the other hand, aluminum forms a dense oxide film in the air, which has good corrosion resistance, allowing the aluminum plate to maintain good performance in special environments and prolong the service life of the equipment.

In the technical scheme, the first buffer column is arranged on the operation platform, the second buffer column is arranged on the connecting plate, when the connecting plate is lowered, the first buffer column abuts against the second buffer column, so as to absorb and disperse the impact force, reduce the vibration of the whole machine during operation, the welding structure can keep higher stability during operation, and the welding quality is improved.

The flat cylindrical structure of welding head 7 makes it more compact in space, which can adapt to the welding requirements of narrow space. Welding head 7 has a smaller contact area during welding, which has higher operation flexibility in narrow space and can easily reach the welding points 31 of complex structures. The straight-line bottom of welding head 7 can accurately align with the welding points 31 during welding, reducing welding deviation caused by mismatching of welding head 7 shape, and improving welding quality. Since welding head 7 is small in size and regular in shape, it can effectively avoid interference with other components during welding, which is suitable for welding scenarios of complex structures and improves welding efficiency.

[0023] More specifically, the welding head 7 is an ultrasonic welding head 7, which is configured to transmit mechanical energy to the welding area through high-frequency vibration, causing the material to rapidly melt and bond locally. This energy transmission method makes the welding process highly concentrated, generating heat only in the area where the welding head 7 contacts the workpiece, reducing the impact on the surrounding material. During ultrasonic welding, the contact time between the welding head 7 and the instrument cover 3 is extremely short. This non-contact welding method reduces physical interference between the welding head 7 and the workpiece, while avoiding thermal damage to the workpiece caused by high temperatures. The compact design and high-frequency vibration of the ultrasonic welding head 7 enable it to perform welding operations in narrow spaces without interfering with other components or structures, ensuring the stability and consistency of the welding process.

[0024] More specifically, as shown in Figure 1 The heating rod is connected to the welding column 6 through the connecting plate 2, and the heating rod conducts heat to the welding head 7 through the welding column 6. By connecting the heating rod to the welding column 6 and conducting heat through the welding column 6, the heating function is closely combined with the welding operation, making it possible to accurately transfer heat to the welding area. The structure of the heating rod is relatively simple, mainly composed of a resistance wire, an insulating layer, and a metal shell, which is easy to manufacture and maintain. By conducting heat through the welding column 6, heat can be concentrated at the welding point 31, reducing the thermal impact on the surrounding material and helping to reduce welding deformation. It is suitable for welding thin plates such as the instrument cover 3. In addition, the design of the heating rod eliminates the need for a heating tube component in the welding column 6, allowing the welding column 6 to be smaller and less likely to interfere with other components during welding.

[0025] More specifically, the connecting plate 2 is an aluminum plate. The aluminum plate has good thermal and electrical conductivity, about 3 times that of iron. It can quickly conduct heat during welding, reducing preheating time and heat loss during welding, thereby improving welding efficiency. On the other hand, aluminum forms a dense oxide film in the air, which has good corrosion resistance, allowing the aluminum plate to maintain good performance in special environments and extend the service life of the equipment.

[0026] More specifically, the welding column 6 is a copper welding column 6. Copper has very high thermal conductivity, allowing the copper welding column 6 to quickly conduct heat and ensure uniform heat distribution during welding.

[0027] More specifically, as shown in Figure 1As shown, the operation platform 1 is provided with at least two profiling bases 4, by providing a plurality of profiling bases 4, so that the welding tooling can simultaneously accommodate a plurality of instrument covers 3 to be welded, each profiling base 4 can independently fix an instrument cover 3, ensure that the instrument cover 3 remains stable during welding, allowing simultaneous welding operation on a plurality of instrument covers 3, improving production efficiency, meeting more use requirements.
