[0001] This utility model relates to the field of feeding equipment technology, and in particular to a feeding and straightening device for thin rods and tubes. Background Technology

[0002] Feeding equipment is a common type of equipment in manufacturing. An existing application (application number 202321971350.3) describes a small bar feeder, comprising a bottom shell and a conveying shell. A guide shell is fixedly connected to the top of the bottom shell, and a guide port is opened at the bottom of the guide shell. A first circular hole is opened at the bottom of the bottom shell, and a first bearing is installed inside the first circular hole. A first rotating shaft passes through the first bearing. A first fixed frame is fixedly connected to the bottom of the bottom shell, and a first motor is fixedly connected to the first fixed frame. The output shaft of the first motor is fixedly connected to the first rotating shaft, and a rotating plate is fixedly connected to one end of the first rotating shaft. A sliding rod is fixedly connected to the top of the rotating plate, and a sliding cylinder is movably sleeved on the surface of the sliding rod. A connecting plate is fixedly connected to the surface of the sliding cylinder. A U-shaped fixed seat is movably connected to one end of the connecting plate via a pin. A movable plate is fixedly connected to the side of the U-shaped fixed seat, and a limit block is fixedly connected to the bottom of the movable plate. A limit groove is opened on the inner wall of the bottom shell, and the limit block is movably connected inside the limit groove.

[0003] While the above-mentioned technology achieves a certain degree of fine rod feeding effect, in actual use, it cannot guarantee that the rods or tubes are completely horizontal when placed in the feed box. This can easily lead to the rods being placed longitudinally or obliquely in the feed box, resulting in them not being able to feed smoothly. Therefore, in order to solve the above-mentioned technical problems, we propose a fine rod and tube feeding and straightening device. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a feeding and alignment device for thin rods and tubes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A feeding and straightening device for thin rods and tubes includes a storage hopper. A rotating shaft is rotatably mounted on the upper side of the middle of the storage hopper. A motor is connected to the rear side of the rotating shaft. A feeding frame is mounted on the middle of the shaft. Several protruding feeding plates are provided at both ends of the outer ring surface of the feeding frame. The end of the feeding plate away from the feeding frame is bent to form a receiving groove for receiving rods. The end of the feeding plate near the receiving groove contacts the middle of the inner bottom surface of the storage hopper. An electric push rod is installed at one end of the rear side of the storage hopper corresponding to the receiving groove. A feeding robotic arm is provided on the upper surface of the storage hopper near the electric push rod.

[0006] Preferably, a storage box is installed at the bottom of the storage hopper, and the storage box has retrieval ports on both sides of its bottom.

[0007] Preferably, a vibration motor is installed on both sides of the bottom of the storage hopper, and a sealing door is provided at the retrieval port.

[0008] Preferably, the bottom surface of the storage hopper has two openings, and the end of the material feeding plate away from the material feeding frame is located inside the opening.

[0009] Preferably, the inner side of the feeding plate near the feeding frame is provided with a flow guide seat, and the surface of the flow guide seat near the receiving groove is provided with an inclined flow guide surface.

[0010] Preferably, the guide seat is hollow inside, and both ends of the guide seat are flush with the side panel of the feed plate.

[0011] Preferably, the upper end of the storage hopper is provided with an mounting plate, and the feeding robot arm is mounted on the upper surface of the mounting plate by bolts.

[0012] Preferably, it also includes a control unit and a position sensor. The control unit is electrically connected to the motor, the electric push rod, and the feeding robot arm. The position sensor is installed inside the storage hopper at the position corresponding to the receiving slot to detect the position of the rod-shaped material. The control unit controls the movement of the electric push rod based on the signal from the position sensor.

[0013] The beneficial effects of the thin rod and tube feeding and alignment device proposed in this utility model are as follows: 1. In this utility model, the rotation of the feeding plate can move the rod-shaped materials placed inside the storage hopper, causing them to move continuously. The rod-shaped materials placed horizontally with both ends facing the front and rear sides are directly picked up and fed by the feeding plate. During the subsequent continuous rotation, the remaining rod-shaped materials are moved to continuously adjust the angle of the vertically placed rod-shaped materials until they are finally picked up by the feeding plate. Since a feeding robot arm is installed at the top of the storage hopper, the feeding robot arm can also straighten the rod-shaped materials inside the storage hopper while feeding. Therefore, when using this solution, the operator can choose the lower-cost electric push rod and feeding plate to achieve the feeding and rod-shaped material straightening effect according to their own production needs, or use the higher-cost feeding robot arm for high-precision feeding and rod-shaped material straightening. The setting of the vibration motor also facilitates the automatic straightening of the rod-shaped materials inside the storage hopper.

[0014] 2. The design of the retrieval port in this utility model allows for the convenient removal of debris or accidentally dropped bar stock from the storage hopper after it enters the storage box; it also facilitates the dropping of debris from the storage hopper into the storage box. The opening facilitates the receiving groove of the feeding plate to accommodate the bar stock. The guide seat prevents the bar stock from entering the inside of the feeding plate and affecting the pushing of the electric push rod when the feeding plate is feeding the bar stock. The mounting plate facilitates the installation and disassembly of the feeding robot arm.

[0015] 3: The control unit and position sensor in this utility model enable the movement of the electric push rod to coordinate with the rotation of the feeding plate. When the position sensor detects that the rod-shaped material is brought to the predetermined position by the feeding plate, the control unit controls the electric push rod to extend and push the rod-shaped material to be fed, thus realizing automated operation. The feeding robot arm is programmed and controlled by the control unit and can be equipped with a vision system or a gripper to achieve high-precision gripping, alignment and feeding, thereby improving feeding efficiency and accuracy.

[0018] 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.

[0019] Example 1 Reference Figures 1-4 A feeding and straightening device for thin rods and tubes includes a storage hopper 1. A rotating shaft 2 is rotatably mounted on the upper side of the middle of the storage hopper 1. A motor 3 is connected to the rear side of the rotating shaft 2. A feeding frame 4 is installed in the middle of the shaft of the rotating shaft 2. Several protruding feeding plates 5 are provided at both ends of the outer ring surface of the feeding frame 4. The end of the feeding plate 5 away from the feeding frame 4 is bent to form a receiving groove 6 for receiving rods. The end of the feeding plate 5 near the receiving groove 6 is in contact with the middle of the inner bottom surface of the storage hopper 1. An electric push rod 7 is installed at the rear end of the storage hopper 1 corresponding to the receiving groove 6. A feeding mechanical arm 8 is provided on the upper surface of the storage hopper 1 near the electric push rod 7.

[0020] This embodiment also includes a control unit and a position sensor (not shown in the figure). The control unit is a PLC or microcontroller, electrically connected to the motor 3, the electric push rod 7, and the loading robotic arm 8. The position sensor is installed inside the storage hopper 1 at the position corresponding to the receiving slot 6, and is used to detect whether the rod-shaped material has been brought to a predetermined position by the material guide plate 5. When the position sensor detects the rod-shaped material, the control unit controls the electric push rod 7 to extend, pushing the rod-shaped material from the storage hopper 1 to the conveyor belt. The loading robotic arm 8 is a multi-joint robotic arm (such as a six-axis robotic arm), with a pneumatic gripper or servo gripper at the end. It is programmed and controlled by the control unit to achieve automatic gripping, alignment, and loading. The loading robotic arm 8 can also be equipped with a vision system to identify the position and posture of the rod-shaped material, improving loading accuracy.

[0021] Example 2 Reference Figures 1-4 While all other parts are the same as in Example 1, the difference between this example and Example 1 is that: A storage box 9 is installed at the bottom of the storage hopper 1. The storage box 9 has retrieval ports 12 on both sides of its bottom. The retrieval ports 12 allow debris or accidentally dropped bars inside the storage hopper 1 to be easily removed from the storage box 9. Vibration motors 13 are installed on both sides of the bottom of the storage hopper 1. The retrieval ports 12 are equipped with sealing doors. The vibration motors 13 facilitate the automatic alignment of the bars inside the storage hopper 1 and also cause debris inside the storage hopper 1 to fall into the storage box 9. The bottom surface of the storage hopper 1 has two openings. The end of the material feeding plate 5 away from the material feeding frame 4 is located in the opening. The openings facilitate the receiving groove of the material feeding plate 5 to receive the bars.

[0022] A guide seat 10 is provided on the inner side of the feeding plate 5 near the feeding frame 4. The surface of the guide seat 10 near the receiving groove 6 is provided with an inclined guide surface. The setting of the guide seat 10 can prevent the bar material from entering the inner side of the feeding plate 5 and affecting the pushing of the electric push rod 7 when the feeding plate 5 feeds the bar material. The guide seat 10 is hollow inside. The two ends of the guide seat 10 are flush with the side panel of the feeding plate 5. The upper end of the storage hopper 1 is provided with a mounting plate 11. The feeding robot arm 8 is installed on the upper surface of the mounting plate 11 by bolts. The setting of the mounting plate 11 facilitates the installation and disassembly of the feeding robot arm 8.

[0023] Operating principle and advantages: In use, the storage hopper 1 is used to hold the bar or tube material to be loaded. These bar or tube materials are collectively referred to as rod-shaped materials. When loading the rod-shaped materials, personnel first directly put numerous rod-shaped materials into the storage hopper 1. Then, the motor 3 drives the rotating shaft 2 to rotate, which in turn drives the material feeding frame 4 to rotate. This material feeding frame 4 drives the material feeding plate 5 to rotate. As the material feeding plate 5 rotates, the receiving groove 6 at the end of the material feeding plate 5 oscillates against the rod-shaped materials. That is, when the material feeding plate 5 passes over the bottom surface of the storage hopper 1, its… The two ends of the rod-shaped material placed at the front and back are received by the receiving groove 6 of the feeding plate 5, so that when the feeding plate 5 rotates, it drives the rod-shaped material to move synchronously until the rod-shaped material is moved above the storage hopper 1. At this time, the position sensor detects the position of the rod-shaped material. When the rod-shaped material reaches the predetermined position, the control unit controls the electric push rod 7 to push the rod-shaped material, so that the rod-shaped material moves from the storage hopper 1 to the conveyor belt on the side of the storage hopper 1, thereby completing the feeding process. During this process, the feeding plate 5 automatically feeds the upright rod-shaped material.

[0024] In the aforementioned process, the rotation of the feeding plate 5 agitates the rod-shaped materials placed inside the storage hopper 1, causing them to move continuously. The horizontally placed rod-shaped materials with both ends facing forward and backward are directly picked up and fed by the feeding plate 5. During subsequent rotation, the remaining rod-shaped materials are agitated, causing the vertically placed rod-shaped materials to continuously adjust their angle until they are finally picked up by the feeding plate 5. Furthermore, since a feeding robotic arm 8 is installed at the upper end of the storage hopper 1, controlled by a control unit, its end gripper can grasp and straighten the rod-shaped materials before placing them in the designated position, achieving high-precision feeding. Therefore, when using this solution, personnel can choose the lower-cost electric push rod 7 in conjunction with the feeding plate 5 to achieve feeding and rod-shaped material straightening, or use the higher-cost feeding robotic arm 8 for high-precision feeding and rod-shaped material straightening, depending on their production needs. The vibration motor 13 also facilitates the automatic straightening of the rod-shaped materials inside the storage hopper 1.

[0025] Furthermore, the design of the retrieval port 12 allows for easy removal of debris or accidentally dropped bar stock from the storage hopper 1 after it enters the storage box 9; it also facilitates the removal of debris from the storage hopper 1 into the storage box 9. The opening facilitates the receiving groove of the feeding plate 5 to accommodate the bar stock. The guide seat 10 prevents the bar stock from entering the inside of the feeding plate 5 and affecting the pushing of the electric push rod 7 when feeding the bar stock. The mounting plate 11 facilitates the installation and removal of the feeding robot arm 8. The control unit and position sensor enable automatic coordination between the electric push rod 7 and the feeding plate 5, improving the reliability and efficiency of feeding. The programmable control of the feeding robot arm 8 allows it to adapt to complex feeding requirements, enhancing the level of automation.

[0026] 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.
