Description

Technical Field

[0001] This utility model relates to the technical field of automatic feeding devices, specifically a hydraulic valve automatic feeding device. Background Technology

[0002] An automatic hydraulic valve feeding device is a mechanical device used in automated production processes to automatically supply hydraulic valves to the next process. Back pressure valves are a type of hydraulic valve that maintains a certain back pressure (i.e., the minimum pressure in the system) in a hydraulic system to ensure that the oil in the system flows stably to the parts requiring pressure, while also preventing the oil from being sucked out of the tank. During the processing of back pressure valves, an automatic hydraulic valve feeding device is typically used to remove the valve body from the hopper for feeding.

[0003] Currently, in the automatic feeding process of back pressure valve bodies, after inspection, intact back pressure valve bodies are placed in the hopper for subsequent retrieval. However, the valve bodies in the hopper are usually stacked together. To facilitate connection, the valve body ports are typically threaded. During the stacking and mutual friction of multiple valve bodies in the hopper, the threads at the ports are prone to wear, resulting in defects. Furthermore, the automatic feeding device for hydraulic valves rarely performs a second inspection, which can easily lead to the feeding of defective back pressure valve bodies, thus affecting the subsequent processing quality. Therefore, this utility model proposes an automatic feeding device for hydraulic valves. Utility Model Content

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model provides a technical solution: an automatic hydraulic valve feeding device includes a base plate 1, with a first robotic arm 4 and a second robotic arm 5 fixedly connected to the top of the base plate 1. The top of the base plate 1 is provided with a conveying mechanism 6 and a detection mechanism 8, and the conveying mechanism 6 and the detection mechanism 8 are both located between the first robotic arm 4 and the second robotic arm 5. A feeding rack 2 is fixedly connected to the top of the base plate 1, and multiple back pressure valve bodies 3 are placed inside the feeding rack 2. The first robotic arm 4 is located on one side of the feeding rack 2 and is used to grasp the back pressure valve bodies 3 inside the feeding rack 2. The second robotic arm 5 is used to grasp the back pressure valve bodies 3 on the rotating tray 606.

[0023] According to the overall structure of the device, the first robotic arm 4 grabs the back pressure valve body 3 inside the feeding rack 2 and transports it through the conveying mechanism 6. During the transport process, the back pressure valve body 3 is inspected by the detection mechanism 8, and back pressure valve bodies 3 with worn threads at the port are screened out. These defective back pressure valve bodies 3 are then picked up and discharged by the second robotic arm 5, while intact back pressure valve bodies 3 are picked up and loaded to ensure the quality of subsequent processing.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the conveying mechanism 6 includes a pair of drive wheels 601, with a conveyor belt 602 drivingly connected between the outer walls of the pair of drive wheels 601. A rotating rod 603 is fixedly connected to the bottom end of each pair of drive wheels 601, and the bottom end of the rotating rod 603 on one side is rotatably connected to the top end of the base plate 1. A motor 604 is fixedly connected to the top end of the base plate 1, and the output end of the motor 604 is fixedly connected to the bottom end of the rotating rod 603 on the other side. Multiple rotating trays 606 are slidably connected to the top end of the base plate 1, and connecting plates are fitted onto the outer walls of each of the multiple rotating trays 606. 605, and the outer wall of the rotating pallet 606 is rotatably connected to the inner wall of the connecting plate 605. One end of each of the multiple connecting plates 605 is fixedly connected to the outer wall of the conveyor belt 602. The bottom end of each of the multiple rotating pallets 606 is fixedly connected to a movable rod 607, and the bottom end of the movable rod 607 is fixedly connected to a sliding block 9. The top of the bottom plate 1 is chiseled with a groove 10, and multiple sliding blocks 9 are located in the groove 10 and are slidably connected to it. The top of each of the multiple rotating pallets 606 is chiseled with a V-shaped groove 7, and the outer wall of the back pressure valve body 3 is in contact with the inner wall of the V-shaped groove 7.

[0025] With the setting of the conveying mechanism 6, the motor 604, together with a pair of transmission wheels 601, drives the conveyor belt 602 to move slowly, which in turn drives the connecting plate 605 and the rotating tray 606 to move slowly. The rotating tray 606 then drives the back pressure valve body 3, which is fitted on the V-shaped groove 7, to be conveyed. At the same time, the movable rod 607 moves synchronously with the rotating tray 606 and drives the sliding block 9 to slide in the slide groove 10, so as to assist the movement of the connecting plate 605 and the rotating tray 606 and keep them moving. The back pressure valve body 3, after being conveyed, moves to the second robot arm 5, and the second robot arm 5 grabs the back pressure valve body 3 for loading.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the detection mechanism 8 includes a camera frame 801 fixedly connected to the top of the base plate 1. A detection camera 802 is fixedly connected to the top of the camera frame 801. Gears 804 are sleeved on the outer walls of multiple movable rods 607. A connecting rod 803 is fixedly connected to one end of the camera frame 801. A rack plate 805 is fixedly connected to one end of the connecting rod 803, and the rack plate 805 meshes with the gears 804. A side plate 11 is fixedly connected to one end of the camera frame 801, and an alarm 12 is fixedly connected to the top of the side plate 11. The detection camera 802 is electrically connected to the alarm 12 and the second robotic arm 5.

[0027] With the setting of the detection mechanism 8, the detection camera 802 can detect the threads at the port of the conveyed back pressure valve body 3, and drive the rotating tray 606 and the back pressure valve body 3 to rotate through the meshing transmission between the rack plate 805 and the gear 804, so that the detection camera 802 can perform a full and comprehensive inspection of the back pressure valve body 3. After the detection camera 802 finds wear on the threads at the port of the back pressure valve body 3, it will send feedback to the alarm 12 and the second robot arm 5 respectively. The alarm 12 will sound an alarm, and at the same time, the second robot arm 5 will grab the defective back pressure valve body 3 and place it into the corresponding defect collection container.

[0028] Working principle: First, the detection camera 802 is adjusted to a suitable detection angle via the camera mount 801. Then, the first robotic arm 4 grabs the back pressure valve body 3 inside the feeding rack 2 and places it on the rotating tray 606. At the same time, the motor 604 is started, which, together with a pair of transmission wheels 601, drives the conveyor belt 602 to move slowly. With the sliding assistance of the sliding block 9 and the slide groove 10, the connecting plate 605, the rotating tray 606, and the movable rod 607 move slowly with the conveyor belt 602, causing the rotating tray 606 to move the back pressure valve body 3 slowly. When it moves to the detection area, the detection camera 802 detects the thread at the port of the back pressure valve body 3, while the movable rod... The gear 804 on 607 begins to mesh with the rack plate 805. Under the action of meshing transmission, the gear 804 and the movable rod 607 rotate, causing the rotating tray 606 and the back pressure valve body 3 to rotate. This allows the inspection camera 802 to more fully and comprehensively inspect the threads at the port of the back pressure valve body 3. When wear is detected in the threads, feedback is sent to the alarm 12 and the second robot arm 5. The alarm 12 sounds an alarm, and when the defective back pressure valve body 3 moves to the second robot arm 5, the second robot arm 5 picks up the defective back pressure valve body 3 and places it into the corresponding defect collection container, while picking up the intact back pressure valve body 3 for loading.

[0029] The wiring diagrams for the first robotic arm 4, the second robotic arm 5, the motor 604, the detection camera 802, and the alarm 12 in this solution are common knowledge in the field. Their working principles are well-known technologies, and the appropriate models are selected according to actual use. Therefore, the control methods and wiring layouts for the first robotic arm 4, the second robotic arm 5, the motor 604, the detection camera 802, and the alarm 12 will not be explained in detail.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
