Description

Technical Field

[0001] This utility model belongs to the field of material guide rack technology, specifically referring to a material guide rack for machining. Background Technology

[0002] In the field of machining, the guide rack is a key piece of equipment for material conveying and positioning, and its performance directly affects production efficiency and processing accuracy.

[0003] Existing guide racks are usually used in conjunction with robotic arms. The robotic arms grab materials, and the guide rack is equipped with cameras to capture images. After feature extraction and feature matching, and combined with the relative position information between the features, the robotic arms are guided to position themselves in the camera coordinate system, reducing the deviation when grabbing objects.

[0004] However, this method cannot completely avoid grasping errors. When grasping errors occur, the robotic arm may collide with the material previously placed on the rack during the unloading process. To address this issue, a guide rack for machining is proposed. Utility Model Content

[0005] The technical problem this invention aims to solve is that the robotic arm may collide with materials previously placed on the rack during the unloading process.

[0006] To achieve the above functions, the technical solution adopted by this utility model is as follows: A guide rack for machining includes two supports arranged opposite to each other, and a limiting plate arranged opposite to each other on the upper end of the two supports. A moving component is provided on the limiting plate. The moving component includes two horizontal plates fixedly connected opposite to each other between the two limiting plates. A sliding plate is slidably arranged between the two horizontal plates, and a mounting base is fixedly connected to the lower end of the sliding plate. A robotic arm is fixedly arranged at the lower end of the mounting base. Multiple sets of fixing plates are arrayed on the supports, and multiple L-shaped plates are slidably arranged on the fixing plates. An anti-collision component is provided between the L-shaped plates and the fixing plates. A camera for cooperating with the robotic arm is provided on one of the supports.

[0007] Furthermore, the moving component also includes a servo motor fixed between the two horizontal plates, and the output end of the servo motor is connected to a lead screw threadedly connected to the slide plate, the other end of the lead screw being vertically connected to the inner side of the limiting plate.

[0008] Furthermore, the anti-collision component includes a second magnet plate fixedly disposed on one side wall of the L-shaped plate, a limit strip is provided opposite to the lower end of the L-shaped plate, and a sliding groove adapted to the limit strip is provided on the fixed plate.

[0009] Furthermore, a spring is fixedly installed on the inner side wall below the L-shaped plate, and the other end of the spring is connected to the side wall of the fixed plate. The inner side of the spring is provided with damping at both ends, which are fixedly connected to the L-shaped plate and the fixed plate respectively.

[0010] Furthermore, a magnet plate one that cooperates with the magnet plate two is fixedly disposed at the lower end of the robotic arm.

[0011] Furthermore, the damping is provided using a linear viscous spring damping system.

[0012] The beneficial effects of this utility model by adopting the above structure are as follows:

[0013] By having the second magnet plate on the L-shaped plate cooperate with the first magnet plate at the lower end of the robotic arm, when the robotic arm approaches the material, the first magnet plate and the second magnet plate are of the same pole and generate a repulsive force. The L-shaped plate moves to one side to avoid the robotic arm carrying the material, thereby reducing collisions caused by inaccurate material grasping. Attached Figure Description

[0021] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example:

[0023] refer to Figure 1-3 As shown, in order to achieve the above functions, the technical solution adopted by this utility model is as follows: A guide rack for machining includes two supports 1 arranged opposite to each other, and a limiting plate 2 arranged opposite to each other on the upper end of the two supports 1. A moving component is provided on the limiting plate 2. The moving component includes two horizontal plates 3 fixedly connected opposite to each other between the two limiting plates 2. A sliding plate 33 is slidably arranged between the two horizontal plates 3. A mounting base 34 is fixedly connected to the lower end of the sliding plate 33. A robotic arm 35 is fixedly arranged at the lower end of the mounting base 34. Multiple sets of fixing plates 11 are arranged in an array on the support 1. Multiple L-shaped plates 5 are slidably arranged on the fixing plates 11. An anti-collision component is provided between the L-shaped plates 5 and the fixing plates 11. A camera 4 for cooperating with the robotic arm 35 is provided on one of the supports 1.

[0024] like Figure 1-3 As shown, the moving component also includes a servo motor 31 fixed between two horizontal plates 3, and the output end of the servo motor 31 is connected to a lead screw 32 threadedly connected to the slide plate 33. The other end of the lead screw 32 is vertically connected to the inner side of the limiting plate 2. The robotic arm 35 controls its movement in the coordinate system through the camera 4 and the returned data and the servo motor 31 to grasp the material.

[0025] like Figure 4 and Figure 5 As shown, the anti-collision assembly includes a second magnetic plate 51 fixedly mounted on one side wall of the L-shaped plate 5. A first magnetic plate 36, which cooperates with the second magnetic plate 51, is fixedly mounted at the lower end of the robotic arm 35. When the robotic arm 35 grabs material and passes the second magnetic plate 51 at the L-shaped plate 5, the L-shaped plate 5 slides to one side to avoid collisions between materials. A limit strip 52 is provided at the lower end of the L-shaped plate 5, and a groove adapted to the limit strip 52 is provided on the fixed plate 11 to limit the horizontal movement of the L-shaped plate 5. A spring 54 is fixedly installed on the inner side wall below the sliding L-shaped plate 5, and the other end of the spring 54 is connected to the side wall of the fixed plate 11. A damper 53 is provided on the inner side of the spring 54, with its two ends fixedly connected to the L-shaped plate 5 and the fixed plate 11 respectively. The damper 53 adopts a linear viscous spring damping setting. When the magnet plate 2 51 and the magnet plate 1 36 move away from each other, the spring 54 provides a thrust to restore the L-shaped plate 5 to its original position. The damper 53 absorbs the vibration of the spring 54 and maintains the stability of the L-shape when it returns to its original position.
