Description

Technical Field

[0001] This utility model relates to the technical field of door panel frame assembly tools, and in particular to door panel frame integrated assembly equipment. Background Technology

[0002] The automotive door panel assembly is a crucial component of the vehicle's interior. It directly impacts the vehicle's visual appeal and passenger comfort, and integrates various functional components such as armrests, map pockets, switch panels, and speaker covers. A typical automotive door panel assembly mainly consists of the door panel, a frame, and various functional accessories. The door panel, as an exterior component, determines the visual style and surface texture of the interior; while the frame, as a structural support, provides the necessary rigidity and strength for the door panel and lays the foundation for the installation of other accessories.

[0003] In the manufacturing process of door trim assemblies, a reliable connection between the door panel and the frame is crucial. Currently, the industry commonly uses welding (such as ultrasonic welding, hot plate welding, etc.) to fix the door panel to the frame. This connection method has advantages such as high connection strength, good aesthetics (no visible fasteners), and high efficiency.

[0004] However, existing welding assembly equipment typically involves first positioning the frame on the welding fixture, then sequentially moving individual door panels or other components to be welded to their corresponding positions on the frame for positioning and pressing, before finally initiating welding. This sequential "positioning and welding" operation mode results in a long overall assembly cycle for individual products, severely restricting production pace and assembly efficiency.

[0005] Furthermore, door trim assemblies typically consist of multiple components or areas that need to be welded to the frame, and the shapes, positions, and welding requirements of these components vary. This necessitates that existing assembly equipment be equipped with multiple independent positioning and pressing devices for specific components. This design results in a complex overall equipment structure, a large number of parts, high manufacturing costs, and significant space consumption on the production line. Simultaneously, the large workload involved in debugging and maintaining multiple devices increases equipment failure rates and the difficulty of production management. Utility Model Content

[0006] To address the low assembly efficiency caused by the sequential positioning and pressing of individual components during the welding and assembly of automotive door trim panels in existing technologies, and the complex equipment structure and numerous parts resulting from the need for multiple independent positioning and pressing devices, this utility model provides an integrated door panel frame assembly device. This device aims to achieve simultaneous positioning and pressing of multiple welding points, thereby significantly improving production efficiency and simplifying the equipment structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A door panel frame integrated assembly device includes at least one welding device, a support plate, at least one placement fixture and at least one positioning component disposed on the support plate. The positioning component surrounds at least one side of the placement fixture.

[0008] Each positioning component includes a connecting rod, a plurality of spaced-apart limiting hammers connected at one end to the connecting rod, and a drive unit for driving the connecting rod to rotate. The drive unit drives the connecting rod to rotate, thereby causing all the limiting hammers on it to swing synchronously, achieving one-time, integrated pressing and fixing of the workpieces to be welded at the corresponding positions of all the limiting hammers.

[0009] Furthermore, the drive unit includes an electric push cylinder and a linkage connected to the piston rod of the electric push cylinder. The linkage preferably employs a rack and pinion mechanism, including a rack connected to the piston rod and a gear fixedly connected to one end of the connecting rod. The meshing of the rack and gear converts the linear motion of the electric push cylinder into the rotational motion of the connecting rod.

[0010] Furthermore, the connecting rod is rotatably connected to the support plate by multiple spaced limiting blocks, ensuring the stability and structural strength of the connecting rod during rotation.

[0011] Furthermore, the limiting hammer is detachably and slidably connected to the connecting rod, which facilitates adjustment and replacement according to the welding points of different workpieces, thereby enhancing the versatility of the equipment.

[0012] Compared with existing technologies, the advantages of this utility model are as follows: By adopting a linkage design in which a single drive unit drives the connecting rod and drives multiple spaced limit hammers on it to rotate synchronously, one-time, integrated positioning and pressing of multiple welding points of the door panel and frame is achieved, which improves assembly efficiency, simplifies the equipment structure, reduces the number of parts, and lowers manufacturing costs and maintenance complexity; in addition, the detachable and sliding design of the limit hammers on the connecting rod increases the versatility and flexibility of the equipment, which can quickly adapt to the production needs of different products; and the structure of the connecting rod being stably supported by the limit blocks also effectively ensures the synchronicity of the action of each pressing point and the consistency of the pressing force, providing a reliable guarantee for welding quality.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example: See Figures 1 to 5 The door panel frame integrated assembly equipment of this utility model includes a protective frame 1. Safety light curtains 7 are installed on the inner walls of the front ends of both sides of the protective frame 1, and a touch screen control box 8 is installed on one side of the protective frame 1. An equipment frame 2 is provided inside the protective frame 1. A control component is provided at the rear end of the equipment frame 2, and an assembly component is installed on the equipment frame 2. The workpiece assembly is automated through the cooperation of the control component and the assembly component. The control component includes an electrical control cabinet 3 installed on one side of the rear end of the equipment frame 2. A warning light is installed on the top surface of the electrical control cabinet 3. A robot control cabinet 5 is provided on the other side of the equipment frame 2. An ultrasonic control box 6 is installed on the top surface of the robot control cabinet 5. The lower ends of the robot control cabinet 5 and the electrical control cabinet 3 are fixed to the equipment frame 2 through mounting bases. The robot control cabinet 5 and the ultrasonic control box 6 facilitate the control of the welding equipment 4 to weld the spliced ​​workpieces. The assembly component is used to realize the placement and positioning of the door panel and frame to be welded.

[0017] Specifically, the equipment frame 2 is provided with a support plate 9, and the support plate 9 is provided with at least one placement fixture. The placement fixture is used to hold the skeleton to be welded and has a contoured groove. Each placement fixture is provided with at least one positioning component around its periphery. That is, multiple positioning components can be provided around the outside of a single placement fixture according to the shape of the door panel to be welded or the welding position of other accessories.

[0018] The assembly equipment of this utility model can simultaneously achieve multi-point positioning of the door panel and frame to be welded. Specifically, a single positioning component includes multiple limiting blocks 11 equidistantly arranged on the support plate 9, a connecting rod 12 rotatably connected to the upper end of several limiting blocks 11, multiple limiting hammers 13 configured on the connecting rod 12, and a corresponding drive unit. The limiting hammers 13 are detachably connected to the connecting rod 12. For example, an approximately "U"-shaped mounting opening can be formed at one end of the limiting hammer 13, and the mounting opening can be locked with bolts to reliably connect the limiting hammer 13 to the connecting rod 12. When the mounting opening is loosened, the limiting hammer 13 can slide along the connecting rod 12 according to different welding requirements, thereby flexibly adjusting the installation position.

[0019] The drive unit drives the connecting rod 12 to rotate, causing the limiting hammer 13 to press against the corresponding positioning point or release the pressing action on the door panel and frame. Specifically, the drive unit includes an electric cylinder 10 and a linkage connected to the piston rod of the electric cylinder 10. The linkage includes a rack connected to the piston rod of the electric cylinder and a gear fixedly connected to one end of the connecting rod 12; the rack meshes with the gear. When the piston rod of the electric cylinder 10 extends, it drives the gear to rotate through the rack, thereby rotating the connecting rod 12 and controlling the limiting hammer 13.

[0020] Furthermore, in order to be suitable for different positioning positions, the pressure head of the limiting hammer 13 is detachably connected to the free end of its hammer body, and the corresponding pressure head can be replaced according to different positioning requirements.

[0021] Working Principle: In the use of this utility model, the workpieces to be assembled are first spliced ​​together, and then the spliced ​​workpieces are placed in the placement fixtures of the support plates 9 installed on both sides of the top surface of the equipment frame 2. After the workpieces are placed, the control command is sent through the touch screen control box 8 installed on one side of the protective frame 1 to start the electric push cylinder 10 installed on the support plate 9. The electric push cylinder 10 drives the connecting rod 12 to rotate, so that multiple limit hammers 13 press against the corresponding positioning points at the same time, thereby achieving stable fixation of the workpieces to be spliced. Then, the parameters are set and control data is sent through the touch screen control box 8. After receiving the data, the robot control cabinet 5 installed on the other side of the equipment frame 2 will control the robot on the base installed at the rear of the equipment frame 2 to drive the welding equipment 4 on it to move precisely to the position to be welded. At the same time, the ultrasonic control box 6 installed on the top surface of the robot control cabinet 5 will also start synchronously, controlling the ultrasonic welding mechanism to emit ultrasonic waves. The ultrasonic waves are then used to weld and assemble the workpieces fixed by the limiting hammer 13. Throughout the welding and assembly process, the safety light curtains 7 installed on the inner walls of the front sides of the protective frame 1 will remain activated to monitor the surrounding environment in real time. If any object accidentally touches the laser beam emitted by the safety light curtain 7, the equipment will immediately trigger an alarm mechanism. At this time, the warning light on the top of the electrical control cabinet 3 installed on one side of the rear of the equipment frame 2 will quickly activate and emit a warning signal to warn nearby personnel to pay attention to safety and avoid accidental contact that could affect the normal assembly process. After the welding and assembly of the workpieces is completed, the touch screen control box 8 sends a command to control the electric push cylinder 10 to operate in reverse, driving the rack, gear and connecting rod 12 to move in reverse, causing the limiting hammer 13 to lift and release the workpiece. Then, the staff can remove the assembled workpiece from the support plate 9, thus completing the current assembly operation.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
