Description

Technical Field

[0001] This application relates to the field of automotive parts assembly technology, and more specifically to a welding apparatus for automotive trim frames. Background Technology

[0002] As an important component of automotive interiors, trim frames not only serve a protective and decorative function but also directly affect the aesthetics and overall quality of the vehicle's interior. With the rapid development of the automotive industry, the requirements for the production efficiency and quality of trim frames are becoming increasingly stringent. Welding is a crucial process in the manufacturing of trim frames, as its quality directly affects the strength and appearance of the frame. Current welding technologies for trim frames primarily involve manual welding of each connection point, which is time-consuming and requires workers to maintain high concentration for extended periods while manually operating the welding equipment. This high labor intensity can easily lead to worker fatigue, resulting in low production efficiency. Furthermore, manual welding relies heavily on the worker's skill and experience, and different workers' operations can lead to inconsistent weld quality, with variations in weld strength and appearance. Therefore, there is still a need for a welding device for automotive trim frames that can replace manual welding and offer higher welding efficiency. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a welding device for automotive decorative frames that replaces manual welding and has higher welding efficiency.

[0004] This application provides a welding device for automotive decorative frames, including a frame. The frame has an installation station and a welding assembly, which are arranged vertically. The installation station is used to install and limit the automotive decorative frame. The frame has an installation plate adapted to the welding assembly, and the welding assembly is mounted on the installation plate. The automotive decorative frame has multiple welding points along its circumference, and the welding assembly has multiple welding heads corresponding to each welding point. In this technical solution, the installation station on the frame ensures the stability and accuracy of the automotive decorative frame during the welding process. The frame uses the installation plate to mount the welding assembly, which welds the welding points of the automotive decorative frame. The welding assembly has multiple welding heads, enabling simultaneous welding of multiple welding points, greatly improving welding efficiency. Since the multiple welding heads correspond one-to-one with the multiple welding points, each welding point is ensured to be fully welded, thereby improving welding quality.

[0005] As an improvement, the installation station is equipped with a positioning groove adapted to the shape of the automotive trim frame. This positioning groove is used to abut and fit the front of the automotive trim frame. In this technical solution, the positioning groove on the installation station is adapted to the shape of the automotive trim frame, simplifying the clamping process. Operators can quickly and accurately place the automotive trim frame in the correct position, ensuring its stability during welding and reducing the possibility of offset or rotation. Furthermore, the positioning groove provides additional support, enhancing the structural stability of the automotive trim frame during welding and helping to reduce welding deformation.

[0006] As an improvement, the welding head is an ultrasonic welding head. In this technical solution, the welding assembly uses an ultrasonic welding head. The ultrasonic welding head generates frictional heat by emitting high-frequency vibrations, melting the contact surfaces of the plastics being welded to achieve welding. This non-contact welding method reduces the impact of external forces on the automotive trim frame. The ultrasonic welding head can precisely control the welding time, power, and pressure to adapt to different welding needs. Ultrasonic welding is fast, which can significantly improve production efficiency.

[0007] As an improvement, the mounting plate is equipped with positioning posts adapted to the installation station. These positioning posts abut against the automotive trim frame, thus limiting the trim frame to its position at the installation station. In this technical solution, the positioning posts on the mounting plate abut against the automotive trim frame, limiting its position at the installation station and preventing displacement or rotation during welding. This ensures precise positioning and stable fixation of the automotive trim frame during welding. The positioning posts simplify the clamping process of the automotive trim frame, allowing operators to quickly and accurately limit its position.

[0008] As an improvement, an elastic buffer is installed on the positioning post. In this technical solution, the elastic buffer installed on the positioning post can absorb the impact and pressure generated during installation and welding, reducing damage to the automotive trim frame and welding equipment.

[0009] As an improvement, the frame includes an upper template, connecting columns, and a lower template. The upper and lower templates are connected by the connecting columns, the mounting plate is connected to the upper template, and the installation station is located on the lower template. In this technical solution, the upper and lower templates are connected by connecting columns, forming a stable frame structure that can withstand various loads and pressures during the welding process, thus enhancing the stability and durability of the entire welding device.

[0010] As an improvement, the connecting column is a lifting rod mechanism, and the upper template drives the mounting plate to rise and fall through the lifting rod mechanism. In this technical solution, the connecting column is designed as a lifting rod mechanism, which allows the upper template to drive the mounting plate to move up and down along the lifting rod, thereby allowing the welding assembly to move up and down, ensuring precise alignment between the welding head and the weld point of the automotive trim frame, and improving welding quality.

[0011] As an improvement, the surface of the installation station used for installing the automotive trim frame is a beveled structure. In this technical solution, setting the surface of the installation station to a beveled structure better suits the shape of the automotive trim frame, thereby providing additional support for the frame, enhancing its structural stability during welding, and helping to reduce welding deformation.

[0012] As an improvement, the automotive trim frame includes a painted part and a chrome-plated part. The painted part is provided with a first welding tab, and the chrome-plated part is provided with a first welding hole adapted to the first welding tab. The first welding tab passes through the first welding hole to form a welding point. In this technical solution, the welding device is mainly used to weld the painted part and the chrome-plated part to form the automotive trim frame. The method of having the painted part and the chrome-plated part pass through the first welding tab and the first welding hole to form a welding point provides a strong connection, reduces the welding gap, and increases the contact area of ​​the welding area, thereby improving the strength and durability of the welding point.

[0021] like Figures 1 to 3As shown, this application discloses a welding device for automotive decorative frames, including a frame 1. The frame 1 has an installation station 2 and a welding assembly 3, which are arranged vertically. The installation station 2 is used to install and limit the automotive decorative frame 4. An installation plate 11 adapted to the welding assembly 3 is installed on the frame 1. The welding assembly 3 is installed on the installation plate 11. The automotive decorative frame 4 has multiple welding points 41 arranged circumferentially. The welding assembly 3 has multiple welding heads 31 corresponding one-to-one with the welding points 41. The installation plate 1 is mounted on the frame 1. Station 2 is used to install the automotive trim frame 4, ensuring the stability and accuracy of the automotive trim frame 4 during the welding process. The frame 1 is equipped with the welding assembly 3 via the mounting plate 11. The welding assembly 3 is used to weld the welding points 41 of the automotive trim frame 4. The welding assembly 3 is equipped with multiple welding heads 31, thereby achieving simultaneous welding of multiple welding points 41, which greatly improves welding efficiency. Since the multiple welding heads 31 correspond one-to-one with the multiple welding points 41, it can be ensured that each welding point 41 is fully welded, thereby improving the welding quality.

[0022] More specifically, such as Figure 2 As shown, the installation station 2 is provided with a positioning groove 21 that matches the shape of the automotive trim frame 4. The positioning groove 21 is used to abut and fit the front of the automotive trim frame 4. The positioning groove 21 on the installation station 2 matches the shape of the automotive trim frame 4, which simplifies the clamping process of the automotive trim frame 4. The operator can quickly and accurately place the automotive trim frame 4 in the correct position, ensuring that the automotive trim frame 4 remains stable during welding, reducing the possibility of displacement or rotation. In addition, the positioning groove 21 provides additional support, enhancing the structural stability of the automotive trim frame 4 during the welding process and helping to reduce welding deformation.

[0023] More specifically, such as Figure 1 As shown, the welding head 31 is an ultrasonic welding head 31. The welding assembly 3 adopts the ultrasonic welding head 31. The ultrasonic welding head 31 generates frictional heat by emitting high-frequency vibrations, which melts the contact surface of the plastic being welded, thus achieving welding. No physical contact is required. This non-contact welding method can reduce the impact of external forces on the automotive trim frame 4. The ultrasonic welding head 31 can precisely control the welding time, power and pressure to adapt to different welding needs. Ultrasonic welding is fast and can significantly improve production efficiency.

[0024] More specifically, such as Figure 1As shown, a positioning post 5 adapted to the installation station 2 is installed on the mounting plate 11. The positioning post 5 is used to abut against the vehicle trim frame 4 so that the vehicle trim frame 4 is limited to the installation station 2. The positioning post 5 is set on the mounting plate 11, and the positioning post 5 abuts against the vehicle trim frame 4, so that the vehicle trim frame 4 is limited to the installation station 2, preventing displacement or rotation during the welding process, ensuring the precise positioning and stable fixation of the vehicle trim frame 4 during the welding process. The positioning post 5 simplifies the clamping process of the vehicle trim frame 4, and the operator can quickly and accurately limit the vehicle trim frame 4.

[0025] More specifically, such as Figure 1 As shown, an elastic buffer 51 is installed on the positioning post 5. The elastic buffer 51 installed on the positioning post 5 can absorb the impact and pressure generated during the installation and welding process, reducing damage to the vehicle trim frame 4 and the welding device.

[0026] More specifically, such as Figure 1 As shown, the frame 1 includes an upper template 12, a connecting column 13, and a lower template 14. The upper template 12 and the lower template 14 are connected by the connecting column 13. The mounting plate 11 is connected to the upper template 12. The mounting station 2 is set on the lower template 14. The upper template 12 and the lower template 14 are connected by the connecting column 13 to form a stable frame structure that can withstand various loads and pressures during the welding process, thereby enhancing the stability and durability of the entire welding device.

[0027] More specifically, such as Figure 1 As shown, the connecting column 13 is a lifting rod mechanism. The upper template 12 drives the mounting plate 11 to rise and fall through the lifting rod mechanism. The connecting column 13 is designed as a lifting rod mechanism so that the upper template 12 can drive the mounting plate 11 to move up and down along the lifting rod, thereby allowing the welding assembly 3 to move up and down, ensuring that the welding head 31 is precisely aligned with the welding point of the automotive decorative frame 4, and improving the welding quality.

[0028] More specifically, such as Figure 1 and Figure 2 As shown, the surface of the installation station 2 used for installing the automotive trim frame 4 is a sloping structure. Setting the surface of the installation station 2 to be a sloping structure is more suitable for the shape of the automotive trim frame 4, thereby providing additional support for the automotive trim frame 4, enhancing the structural stability of the automotive trim frame 4 during the welding process, and helping to reduce welding deformation.

[0029] More specifically, such as Figure 3As shown, the automotive trim frame 4 includes a painted part 42 and a chrome-plated part 43. The painted part 42 is provided with a first welding piece 421, and the chrome-plated part 43 is provided with a first welding hole 431 adapted to the first welding piece 421. The first welding piece 421 passes through the first welding hole 431 to form a welding point 41. The welding device is mainly used to weld the painted part 42 and the chrome-plated part 43 to form the automotive trim frame 4. The painted part 42 and the chrome-plated part 43 are arranged to pass through the first welding hole 431 through the first welding piece 421 to form a welding point 41. This through-type welding method can provide a strong connection, reduce the welding gap, and increase the contact area of ​​the welding area, thereby improving the strength and durability of the welding point 41.

[0030] This application is not limited to the above-described preferred embodiments. Anyone can derive other products in various forms under the guidance of this application. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to that of this application falls within the protection scope of this application.
