Description

Technical Field

[0001] This utility model relates to the field of automotive parts assembly technology, specifically to an upper part positioning device for the front of an automobile in a reciprocating conveyor line. Background Technology

[0002] As China's strategic transformation from "Made in China" to "Intelligent Manufacturing in China" accelerates, intelligent and flexible manufacturing technologies have deeply penetrated various industrial sectors. The automotive industry, as a pillar of the national economy, has taken the lead in this wave of technological innovation. Industrial robots, with their high-precision positioning, high-efficiency operation, flexible programmability, and adaptability to harsh conditions such as high temperatures and dust, have become core equipment in automotive intelligent manufacturing. Faced with the growing demand for personalized vehicles and the pressure of product iteration in the consumer market, many automakers are actively exploring co-production technologies for different car body-in-white models to improve market responsiveness. Among these, flexible welding lines, with their advantages of multi-model compatibility and flexible production switching, have become a key path for industry upgrading. Although their high initial investment costs pose a challenge to enterprise transformation, they cannot stop the industry's progress towards intelligence and flexibility.

[0003] In the manufacturing and assembly of automotive front bulkhead panels, the traditional manual loading and positioning welding methods are facing severe challenges. In the production process of reciprocating conveyor lines, relying solely on manual operation for front bulkhead panel loading not only hinders efficiency but also makes it difficult to guarantee the consistency and stability of welding positions, leading to frequent rework and line stoppages. This extensive operation method not only severely restricts production efficiency but also significantly increases labor costs, material losses, and equipment energy consumption, resulting in persistently high production costs and failing to meet the urgent demands of modern automotive manufacturing for efficient and lean production.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Please see Figures 1 to 5This utility model provides a technical solution: a positioning device for the upper part of an automobile front panel in a reciprocating conveyor line, including a frame 1, two sets of clamping components that can be flipped and opened are provided in the middle of the frame 1, and a hook sensing component for hooking and sensing the front panel is provided in the middle of the frame 1 corresponding to the clamping components.

[0027] The four corners of frame 1 are rigidly fixed to the robot arm through high-strength connectors. This stable assembly method ensures that frame 1 can maintain precise synchronization with the robot arm when performing complex actions such as grasping, handling, and positioning, achieving zero-delay coordinated movement, thereby providing a stable and reliable mobile platform for other components mounted on frame 1.

[0028] The clamping component includes a first cylinder 2 fixedly mounted on the frame 1, a second pressure block 4 is provided on the top rotating shaft of the first cylinder 2, and a second support block 7 adapted to the second pressure block 4 is also provided on the frame 1.

[0029] When the first cylinder 2 starts working, its output linear driving force is converted into rotational torque through the transmission mechanism. Both the first cylinder 2 and the transmission mechanism are existing technologies and will not be described in detail here. This precisely drives the second pressure block 4 to rotate around the rotation axis. When the second pressure block 4 rotates towards the second support block 7, the clamping space formed by the two gradually shrinks, achieving stable clamping of the front panel through preset pressure parameters. Conversely, when the second pressure block 4 rotates away from the second support block 7, the clamping space expands, allowing the front panel to be safely released. The entire process achieves automated and precise material loading and unloading operations.

[0030] The hook-and-feed sensing component includes a third support plate 10 fixedly mounted on the frame 1. A proximity switch 16 for sensing the front cover is provided on one side of the third support plate 10, and a hook-pin cylinder 21 for hooking the front cover is provided on the other side of the third support plate 10.

[0031] The proximity switch 16 is responsible for detecting the front bulkhead. Its installation position is not fixed, but is determined by a comprehensive consideration of multiple factors, including the contour features of the panel, welding process avoidance requirements, and the operating space of the gripper. The switch supports manual adjustment, and this adjustment method is existing technology, so it will not be described in detail here. It has two core functions: First, during the gripping process, by sensing the presence or absence of the front bulkhead, it controls the action of the hook cylinder 21, the first cylinder 2, and the second cylinder 22 via signal feedback, ensuring that the clamping and gripping process is triggered only when the panel is in place. Second, during transportation and positioning, it monitors in real time whether the panel is accurately positioned and promptly identifies deformation caused by factors such as transportation collisions. It provides error prevention warnings through signal anomaly feedback, effectively improving the accuracy and reliability of front bulkhead gripping and assembly.

[0032] The front panel is equipped with a standard hook component that works in conjunction with the hook-pin cylinder 21. This component, as a universal assembly on the production line, enables a reliable mechanical connection. When the hook-pin cylinder 21 is activated, its telescopic hook head precisely engages with the hook component, securing the front panel's position through mechanical locking and ensuring the workpiece's stability during transport and processing. When the front panel is positioned or needs to be transferred to the next process, the hook-pin cylinder 21 retracts, quickly separating the hook head from the hook component, allowing the front panel to smoothly detach from the upper positioning device and ensuring continuous and efficient operation of the production line.

[0033] Please see Figures 1 to 3 A first bracket is fixedly installed in the middle of the frame 1, a first cylinder 2 is fixedly connected to the first bracket, a second cylinder pressure wall 6 is installed on the top rotating shaft of the first cylinder 2, a second pressure block 4 is fixedly connected to the upper surface of the second cylinder pressure wall 6, and a second support block 7 is also set on the first bracket.

[0034] When the first cylinder 2 starts running, the driving torque it generates will cause the second cylinder pressure wall 6 to rotate around the rotation axis. As the second cylinder pressure wall 6 rotates, the second pressure block 4, which is rigidly connected to it, will move synchronously, moving closer to or further away from the second support block 7. Through precise mechanical linkage, the stable clamping and safe release of the front panel are completed, ensuring the efficiency and reliability of the entire operation process.

[0035] Please see Figures 1 to 3 The lower surface of the second cylinder pressure wall 6 is fixedly connected to a third pressure block 9, and the first bracket is also provided with a third support block 12 corresponding to the position of the third pressure block 9.

[0036] When the first cylinder 2 starts operating, its output power will synchronously drive the third pressure block 9 to rotate around the rotating axis. As the third pressure block 9 rotates, it moves closer to or further away from the third support block 12 along a circular trajectory. By precisely controlling the rotation angle, stable clamping and safe release of the workpiece can be achieved, ensuring the efficiency and reliability of the entire operation process.

[0037] Please see Figures 1 to 4 The clamping component also includes a first mounting plate fixedly connected to the frame 1. A second cylinder 22 is fixedly connected to one end of the first mounting plate. Both the first cylinder 2 and the second cylinder 22 are mature rotary cylinder products. Such standardized actuators are widely used in automated production lines. Their working principle, structural design, and technical parameters have formed a complete system in the industry, so this article will not elaborate on their internal structure and operating mechanism. A first support block 14 is fixedly connected to the upper surface of the first mounting plate. A first cylinder pressure wall 15 is fixedly connected to the top rotating shaft of the second cylinder 22, and a first pressure block 13 adapted to the first support block 14 is fixedly connected to the lower surface of the first cylinder pressure wall 15 away from the second cylinder 22.

[0038] When the second cylinder 22 starts running, its output linear driving force is converted into rotational torque through the transmission mechanism, driving the first cylinder pressure wall 15 to rotate around the rotation axis. As the first cylinder pressure wall 15 rotates, the first pressure block 13, which is rigidly connected to it, will synchronously move closer to or away from the first support block 14. Through precise mechanical linkage, stable clamping and safe release of the workpiece are achieved, ensuring that the entire operation process is completed efficiently and reliably.

[0039] Please see Figures 1 to 5 The hook sensing component also includes a second mounting plate fixedly connected to the frame 1. A second support plate 5 is fixedly connected to one end of the upper surface of the second mounting plate. A seventh support block 19 is fixedly connected to the top of the second support plate 5. A third support plate 10 is located at the other end of the upper surface of the second mounting plate. A sixth support block 18 is fixedly installed on the side of the third support plate 10 away from the hook cylinder 21. Two first support plates 3 are provided in the middle of the frame 1. A fifth support block 17 is fixedly connected to the top of the first support plate 3. The two first support plates 3 are located between the two hook sensing components. A fourth support block 11 is fixedly installed on the side of the middle of the frame 1 near the hook sensing component.

[0040] The sixth support block 18, the seventh support block 19, the fifth support block 17, and the fourth support block 11 together form a stable support system. Through multi-point coordinated support, mechanical support is provided from different directions of the front panel, effectively dispersing the weight of the workpiece and external forces, ensuring that the front panel maintains high-precision positioning during processing, assembly, and other processes, avoiding displacement or deformation due to uneven force, and providing reliable stability for subsequent operations.

[0041] In summary, when the automotive front panel is used in the upper part positioning device on the reciprocating conveyor line, the robotic arm carrying the frame 1 first moves the front panel to the position to be gripped. The proximity switch 16 detects the presence and positioning status of the front panel in real time. If the front panel meets the gripping conditions, a signal is transmitted to the control system, triggering the hook cylinder 21 to extend. Its hook head accurately hooks the hooking component of the front panel, completing the initial positioning and fixing.

[0042] Subsequently, the first cylinder 2 and the second cylinder 22 are started synchronously. The first cylinder 2 drives the second pressure block 4 and the third pressure block 9 to rotate and approach the second support block 7 and the third support block 12 respectively. The second cylinder 22 drives the first pressure block 13 to rotate and tighten towards the first support block 14. Through the coordinated clamping of the four sets of pressure blocks and support blocks, uniform pressure is applied from multiple directions of the front panel to achieve stable clamping.

[0043] After clamping, the robotic arm moves the front bulkhead to the designated station according to instructions. Then, after other processes on the front bulkhead are completed, the hook cylinder 21 retracts and disengages, the first cylinder 2 and the second cylinder 22 move in opposite directions, and the pressure block assembly rotates away from the support block, releasing the front bulkhead. The entire process, through precise coordination of the mechanical structure and sensing system, achieves fully automated, high-precision operation of the front bulkhead from gripping and transfer to positioning, effectively improving the operating efficiency and assembly quality of the automotive production line.

[0044] Meanwhile, the upper positioning device for the automotive front bulkhead in the reciprocating conveyor line, through a precisely designed pneumatic control system, executes differentiated pneumatic logic programs based on the structural characteristics and gripping requirements of different front bulkhead panels. By independently adjusting the airflow timing and pressure parameters of each cylinder, the coordinated operation and precise movement of multiple cylinders are achieved, effectively avoiding the risk of interference between components during movement. Whether it is a front bulkhead panel with a complex curved surface or a model with a special structure, the pneumatic control strategy can be flexibly adjusted to ensure that each cylinder completes the clamping and releasing action at the appropriate time, thereby achieving efficient and stable gripping of front bulkhead panels of different specifications, significantly improving the versatility and adaptability of the production line.

[0045] 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.
