Description

Technical Field

[0001] This utility model relates to the field of material feeding technology, specifically to an automatic centering and positioning device for a material tray. Background Technology

[0002] An automobile is a powered means of transportation with four or more wheels that travels on land without relying on tracks or overhead wires. The main functions of an automobile include: carrying people and goods, towing vehicles carrying people and / or goods, and completing specific transportation or operational tasks. Due to its versatility, the automobile has become an indispensable part of modern society. Its design not only considers basic driving performance but also incorporates various safety and comfort features. Automobiles are classified in various ways, mainly into passenger cars and freight cars, as well as special-purpose vehicles designed to complete specific tasks. These special-purpose vehicles may include fire trucks, ambulances, police cars, etc.

[0003] Currently, in the automobile production process, due to the large number of functional components, various functional parts need to be assembled step by step according to the production process. Existing automotive parts are generally fed using material trays. First, the raw materials for the automotive parts are placed in the material tray, then the tray is placed at the feeding point, usually a table or desktop. A robotic arm then picks up the material tray from the table or desktop and moves it into the processing equipment. However, when the material tray is placed on the table or desktop, the robotic arm needs to pick up the material tray at a fixed position according to a set program. Since there is always some error when placing the material tray, there is a possibility of damage to the material tray and the raw automotive parts when the robotic arm picks up the tray. Furthermore, during the movement, due to deviations in the gripping position, there is a possibility of bumps or drops. This results in low material feeding efficiency and product quality, and also poses certain safety hazards. Utility Model Content

[0004] To address the problems in the prior art, this utility model provides an automatic centering and positioning device for material trays. By incorporating a cooperating centering and positioning device body, a centering and closing push plate assembly, and a drive assembly within the automatic centering and positioning device for material trays, automatic centering and positioning of the material trays before being grasped by a robotic arm can be achieved. This significantly improves the feeding efficiency and accuracy of the material trays, and solves the problems in the prior art where human placement of material trays leads to low feeding efficiency, easy damage to the material trays or materials, and safety hazards.

[0005] This utility model provides an automatic centering and positioning device for a material tray, comprising a centering and positioning device body, a centering and closing push plate assembly, and a drive assembly. The centering and positioning device body is fixedly disposed at the feeding point. The centering and closing push plate assembly is movably connected to the centering and positioning device body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model provides an automatic centering and positioning device for a material tray. By setting a cooperating centering and positioning device body, a centering and closing push plate assembly, and a drive assembly within the automatic centering and positioning device for the material tray, the drive assembly can drive the closing push plate in the X-axis direction to close through the closing connecting plate, thereby driving the closing push plate in the Y-axis direction to close, thus achieving synchronous closing and fixing of the material tray in four directions. This enables automatic centering and positioning of the material tray before it is grasped by the robot arm, allowing the robot arm to accurately grasp the material tray at a fixed coordinate for loading. This avoids the possibility of damage to the material tray and automotive parts raw materials due to positional errors when the robot arm grasps the material tray, greatly improving the loading efficiency and accuracy of the material tray.

The centering and closing push plate assembly 2 is movably connected to the centering and positioning device body 1. The driving assembly 3 is fixedly installed on the centering and positioning device body 1 and adapted to the centering and closing push plate assembly 2. The centering and closing push plate assembly 2 includes two X-axis closing push plates 21 and two Y-axis closing push plates 22. A closing connecting plate 23 is provided between the two X-axis closing push plates 21. The driving assembly 3 is drivenly connected to the two X-axis closing push plates 21 through the closing connecting plate 23. A passive connecting plate 24 is provided between the X-axis closing push plates 21 and the Y-axis closing push plates 22. The X-axis closing push plates 21 are drivenly connected to the Y-axis closing push plates 22 through the passive connecting plate 24. In this embodiment, the drive component can drive the closing push plate in the X-axis direction to close via the closing connecting plate, thereby driving the closing push plate in the Y-axis direction to close, thus achieving synchronous closing and fixing of the material tray in four directions. This enables the material tray to be automatically centered and positioned before being grasped by the robot arm, allowing the robot arm to accurately grasp the material tray at fixed coordinates for loading. This avoids the possibility of the robot arm damaging the material tray and automotive parts raw materials due to positional errors when grasping the material tray, and greatly improves the loading efficiency and accuracy of the material tray.

[0019] like Figure 1 As shown, the centering and positioning device body 1 is provided with an X-axis slide rail, and the bottom of the X-axis closing push plate 21 is slidably connected to the X-axis slide rail. The centering and positioning device body 1 is provided with a Y-axis slide rail, and the bottom of the Y-axis closing push plate 22 is slidably connected to the Y-axis slide rail. The closing connecting plate 23 is provided with an X-axis motion inclined slide groove, and the X-axis closing push plate 21 is provided with an X-axis motion guide post, which is slidably connected to the X-axis motion inclined slide groove. The passive connecting plate 24 is provided with a Y-axis motion inclined slide groove, and the Y-axis closing push plate 22 is provided with a Y-axis motion guide post, which is slidably connected to the Y-axis motion inclined slide groove. The driving component is a driving cylinder, which is fixedly installed on the centering and positioning device body 1 and is drivenly connected to the closing connecting plate 23. In this embodiment, when the material tray is placed on the automatic centering and positioning device, the drive cylinder drives the closing connecting plate to close the closing push plate in the X-axis direction, which in turn drives the passive connecting plate to move. The passive connecting plate then drives the closing push plate in the Y-axis direction to close, thereby achieving synchronous closing in four directions to fix and position the material tray.

[0020] As can be seen from the above, this utility model provides an automatic centering and positioning device for a material tray. By setting up a cooperating centering and positioning device body, a centering and closing push plate assembly, and a drive assembly within the automatic centering and positioning device for the material tray, the drive assembly can drive the closing push plate in the X-axis direction to close via the closing connecting plate, thereby driving the closing push plate in the Y-axis direction to close, thus achieving synchronous closing and fixing of the material tray in four directions. This enables automatic centering and positioning of the material tray before it is grasped by the robotic arm, allowing the robotic arm to accurately grasp the material tray at a fixed coordinate for loading. This avoids the possibility of damage to the material tray and automotive parts raw materials due to positional errors when the robotic arm grasps the material tray, significantly improving the loading efficiency and accuracy of the material tray. It solves the problems of low loading efficiency, easy damage to the material tray or materials due to human placement errors, and safety hazards in the prior art.
