Description

Technical Field

[0001] This utility model relates to the field of belt pulley detection technology, specifically to an auxiliary loading and unloading robot. Background Technology

[0002] Patent publication number CN107160418A discloses a dual-rotation, dual-claw gripping robotic arm, including an arm support, a workpiece tray, and a control console located below the arm support. A turntable is positioned below the control console. Below the turntable are a first and a second robotic finger arranged side-by-side. Below the turntable are a first and a second rotating branch, with the first robotic finger positioned at the end of the first rotating branch and the second robotic finger at the end of the second rotating branch. The gripping surfaces of the first and second robotic fingers are concave. The first and second rotating branches rotate independently, and at least one of the first or second rotating branches can retract 8 cm. This invention allows one of the first and second rotating branches to retract independently, enabling the gripping of two workpieces at a time with intervals. Each robotic finger can rotate independently, facilitating workpiece loading and unloading, reducing the robotic arm's travel distance, and increasing efficiency.

[0003] In the existing technology, in order to improve the working efficiency of robotic arms for loading and unloading, dual claws are usually installed on the robotic arms. Each claw needs to be equipped with an independent cylinder to perform gripping and dropping actions. This means that the initial purchase cost of the equipment, the energy consumption during equipment use, and the maintenance cost all increase significantly. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary loading and unloading robot.

[0005] The technical problem solved by this utility model is that each gripper has an independent cylinder, which leads to a significant increase in the manufacturing and operating costs of the equipment.

[0006] This utility model can be achieved through the following technical solution: a six-axis robotic arm is mounted on the top of the base, a signal receiver is electrically connected to the six-axis robotic arm, a connecting plate is fixedly mounted on the output end of the six-axis robotic arm, mounting brackets are fixedly mounted on both sides of the connecting plate, and a clamping mechanism is mounted on each of the two mounting brackets. The clamping mechanism includes two clamping plates that move in opposite directions, and a transmission component is mounted on the connecting plate at the center position between the two clamping mechanisms. The transmission component is used to trigger the two clamping plates in the clamping mechanism to move away from each other.

[0007] A further technical improvement of this utility model is that the clamping mechanism also includes two opposing sliders that are slidably mounted on the side of the mounting frame away from the connecting plate. Springs are fixedly installed between the opposing sides of the two sliders and the mounting frame. The two clamping plates are slidably connected to the sides of the two sliders away from the mounting frame. A screw is threaded through the clamping plate, and the two ends of the screw are rotatably connected through the sides of the slider.

[0008] Furthermore, anti-slip pads are fixedly installed on the opposite sides of both clamping plates.

[0009] Furthermore, a throttle is fixedly installed at one end of the screw.

[0010] Furthermore, the transmission assembly includes a slide plate that is slidably mounted through the mounting frame. Two symmetrical push-pull plates are rotatably mounted on the bottom of the slide plate. The bottom ends of the two push-pull plates are rotatably connected to the tops of the two slide plates respectively. A support plate is fixedly mounted on the connecting plate at the center position between the two mounting frames. The opposite sides of the two slide plates are slidably connected to the support plate. A rotating plate is rotatably mounted on the support plate at the center position above the two slide plates. The bottom of the rotating plate is simultaneously in contact with the tops of the two slide plates.

[0011] Furthermore, a drive motor for rotating the rotating plate is mounted on the support plate, and the drive motor is electrically connected to the signal receiver.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This application rotates the rotating plate clockwise or counterclockwise to trigger the two clamping plates in the two clamping mechanisms to open and close, thereby clamping and releasing the pulley. This reduces the need for drive equipment to open and close the two sets of clamping plates, thus lowering manufacturing and operating costs.

[0014] 2. By rotating the screw, the distance between the two clamping plates in the clamping mechanism can be adjusted, thereby enabling the clamping mechanism to adapt to pulleys of different sizes and improving its applicability. Attached Figure Description

[0020] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0021] Please see Figure 1-3 As shown, this embodiment provides an auxiliary loading and unloading robot, including a base 1, a six-axis robotic arm 2 mounted on the base 1, a signal receiver 3 mounted on the six-axis robotic arm 2, the signal receiver 3 being used to receive wireless signals emitted by the control box in the production workshop, the equipment driving each axis of the six-axis robotic arm 2 being electrically connected to the signal receiver 3, a mechanical claw mounted on the output end of the six-axis robotic arm 2, the mechanical claw including a connecting plate 4, two mounting brackets 5 and two clamping mechanisms 6, the connecting plate 4 being fixedly connected to the output end of the six-axis robotic arm 2, the two mounting brackets 5 being fixedly connected to both sides of the connecting plate 4 respectively, and the two clamping mechanisms 6 being mounted on the two mounting brackets 5 respectively;

[0022] The wireless signals received by the signal receiver 3 control the rotation of each axis of the six-axis robotic arm 2, thereby transporting the clamping mechanism 6 to the position of receiving, detecting and conveying the pulley through the connecting plate 4 and the mounting frame 5 for loading and unloading, thus realizing the automated management of the position transfer of the pulley in the production workshop;

[0023] The clamping mechanism 6 includes two opposing sliders 61 slidably mounted on the side of the mounting frame 5 away from the connecting plate 4. Springs 62 are fixedly mounted between the opposing sides of the two sliders 61 and the mounting frame 5. A clamping plate 63 is slidably mounted on the side of the sliders 61 away from the mounting frame 5. A screw 64 is threaded through the clamping plate 63. The two ends of the screw 64 are respectively rotatably connected to the two sides of the sliders 61. A handle 65 is fixedly mounted on one end of the screw 64. The handle 65 is designed to facilitate manual rotation of the screw 64 by the operator. Anti-slip pads 66 are fixedly mounted on the opposite sides of the two clamping plates 63. The anti-slip pads 66 are used to increase the friction between the clamping plates 63 and the pulley to prevent the pulley from slipping on the clamping plates 63.

[0024] When the two sliders 61 move away from each other, they will compress the two springs 62 respectively, so that the two springs 62 are under force at the same time. When the pressure on the two springs 62 is released, the two sliders 61 will be driven to rebound to their natural state, thereby causing the two sliders 61 to move closer to each other. When the screw 64 is rotated clockwise, the screw 64 will drive the clamping plate 63 connected to it to move along the slider 61 towards the other clamping plate 63, thereby reducing the distance between the two clamping plates 63. Conversely, rotating clockwise will increase the distance between the two clamping plates 63.

[0025] The structure that causes the two sliders 61 to move toward each other includes a sliding plate 7 that is slidably mounted through the mounting bracket 5. Two mutually symmetrical push-pull plates 8 are rotatably mounted on the bottom end of the sliding plate 7. The bottom ends of the two push-pull plates 8 are rotatably connected to the top of the two sliders 61 respectively. A support plate 9 is fixedly mounted on the connecting plate 4 at the center position between the two mounting brackets 5. One side of the sliding plate 7 is slidably connected to one side of the support plate 9. A rotating plate 10 is rotatably mounted on the support plate 9 at the center position above the two sliding plates 7. A drive motor that drives the rotating plate 10 to rotate is mounted on the support plate 9. The drive motor is electrically connected to the signal receiver 3. The bottom of the rotating plate 10 is simultaneously in contact with the top of the two sliding plates 7.

[0026] When the rotating plate 10 rotates clockwise, it presses the top of the slide plate 7 on its right bottom, causing the slide plate 7 to move vertically downward along the mounting bracket 5 on the right side of the rotating plate 10. This causes the two push-pull plates 8, which are rotatably connected to the slide plate 7, to move the two sliders 61 in the clamping mechanism 6 on the mounting bracket 5 away from each other. Simultaneously, the two sliders 61 move the two clamping plates 63 in the clamping mechanism 6 away from each other. When the rotating plate 10 rotates counterclockwise, the clamping mechanism 6 on its left mounting bracket 5 repeats the above operation. At this time, the right end of the rotating plate 10 disengages from the top of the right slide plate 7, releasing the pressure on the top of the slide plate 7. This releases the pressure on the spring 62 in the clamping mechanism 6 on the right side of the rotating plate 10, causing the two sliders 61 to move closer to each other through the rebound of the two springs 62. This causes the two clamping plates 63 to move closer to each other, and the distance between the two clamping plates 63 returns to its original state. At the same time, the sliders 61 that are moving closer to each other also move the slide plate 7 on the mounting bracket 5 vertically upward to the initial height through the push-pull plates 8.

[0027] In use, this invention first adjusts the distance between the two clamping plates 63 within the two clamping mechanisms 6 so that the distance between the two clamping plates 63 is less than the diameter of the pulley. This ensures that when the pulley is clamped between the two clamping plates 63, the pressure applied by the two sliders 61 to the two springs 62 is just enough to cause the springs 62 to rebound onto the two sliders 61, thus driving the two clamping plates 63 to clamp the pulley. Then, the six-axis robotic arm 2 moves the two clamping mechanisms 6 along a pre-designed path. When the six-axis robotic arm 2 moves the clamping mechanism 6 on the right side of the rotating plate 10 to the position where the pulley is received, the wireless signal received by the signal receiver 3 controls the rotating plate 10 to rotate clockwise, increasing the distance between the two clamping plates 63 within the clamping mechanism 6 to a level greater than the diameter of the pulley. Then, the six-axis robotic arm 2 controls the inner circumferential walls of the two clamping plates 63 on the clamping mechanism 6 to move until they are aligned with the outer circumferential walls of the pulley. At the corresponding position, the wireless signal received by the signal receiver 3 will control the rotating plate 10 to rotate counterclockwise back to the initial state. At the same time, the two clamping plates 63 on the clamping mechanism 6 will move closer to each other due to the action of the two springs 62 on the two sliders 61 after the pressure is released, causing the two clamping plates 63 to clamp the pulley. When the six-axis robotic arm 2 moves the pulley on the clamping mechanism 6 to the designated unloading position, the wireless signal received by the signal receiver 3 will continue to control the rotating plate 10 to rotate clockwise, thereby causing the two clamping plates 63 in the clamping mechanism 6 to move away from each other, thereby releasing their clamping of the pulley and placing the pulley in the designated unloading position. When the six-axis robotic arm 2 moves the clamping mechanism 6 on the left side of the rotating plate 10 to the unloading position, the signal received by the signal receiver 3 will cause the rotating plate 10 to rotate in the opposite direction to the above-mentioned rotating plate 10. The movement state of the two clamping plates 63 in the clamping mechanism 6 is the same as above.

[0028] The six-axis robotic arm 2 uses two clamping mechanisms 6 to grip two pulleys at the receiving pulley position, and then places the two pulleys into two dynamic balancing machines that perform pulley runout detection. After the two pulleys have completed the detection, the six-axis robotic arm 2 will use the two clamping mechanisms 6 to grip the two pulleys again, and finally place them onto the conveying equipment in sequence, thereby transporting the detected pulleys to the designated position. When the next batch of pulleys needs to be detected, the above steps can be repeated.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
