Technical Field

[0001] This utility model relates to the field of chip mounter technology, and in particular to a chip mounter mechanism for visual calibration of ultra-micro components. Background Technology

[0002] A pick-and-place machine is a device used to mount electronic components onto printed circuit boards (PCBs). It is widely used in the electronics manufacturing industry, such as the production of mobile phones, computers, home appliances, and automotive electronics. It is a key piece of equipment for automating the mounting of electronic components and improving production efficiency and quality.

[0003] Most existing pick-and-place machines use vision to obtain the position of materials and use suction cups to pick up and fix the materials, and then transfer the materials to the PCB area. However, suction cups have difficulty adsorbing and fixing materials with uneven surfaces. At the same time, the existing vision camera and suction cup are not at the same vertical height, which may cause deviations in the picking process.

[0004] Therefore, to address the above problems, an ultra-micro component visual calibration placement mechanism can be designed to improve the placement mechanism of the placement machine. Utility Model Content

[0005] To overcome the problem that most pick-and-place machines rely on vision to determine the position of materials and use suction cups to pick up and fix the materials before transferring them to the PCB area, the suction cups have difficulty adsorbing and fixing materials with uneven surfaces. In addition, the existing vision camera and suction cup are not at the same vertical height, which may cause deviations in the picking process.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 This utility model provides an embodiment of a micro-component visual calibration patching mechanism, including an operating table 1, a gripper 8, and a drive assembly. A mounting base 9 is disposed above the operating table 1, a camera 7 is disposed on one side of the mounting base 9, and a gripper 8 is disposed at the bottom of the mounting base 9. The gripper 8 is rotatably connected to the mounting base 9. A drive assembly is disposed inside the mounting base 9. An optical path tube 701 is disposed at the bottom of the camera 7, and a first mirror 702 and a second mirror 703 are disposed inside the optical path tube 701. The first mirror 702 and the second mirror 703 are tilted at a 45-degree angle. By using the drive assembly to drive the gripper 8 to rotate and grip the material, the patching machine can pick up materials with uneven upper surfaces. Simultaneously, the first mirror 702 and the second mirror 703 refract light, causing the light entering the mounting base 9 to undergo two refractions in the optical path tube 701 before entering the camera 7. This allows the camera 7 to obtain a field of view directly below the gripper 8, thereby improving the gripping accuracy.

[0024] Please see Figures 1-2In this embodiment, a support base 2 is provided at the bottom of the operating table 1, a first movable frame 3 is provided above the support base 2, a second movable frame 4 is provided on one side of the first movable frame 3, and a third movable frame 5 is provided on one side of the second movable frame 4. The third movable frame 5 is fixedly connected to the mounting base 9. The support base 2, the first movable frame 3, the second movable frame 4, and the third movable frame 5 are slidably connected, and a linear guide rail 6 is provided at the connection point. A first threaded rod 201 is provided above the support base 2, and a first drive motor 202 is provided at one end of the first threaded rod 201. A second threaded rod 301 is provided inside the first movable frame 3, and a second drive motor 302 is provided at one end of the second threaded rod 301. A third threaded rod is provided inside the second movable frame 4. The rod 401 has a third drive motor 402 at one end. The first threaded rod 201 is threadedly connected to the first movable frame 3, the second threaded rod 301 is threadedly connected to the second movable frame 4, and the third threaded rod 401 is threadedly connected to the third movable frame 5. The first drive motor 202 drives the first threaded rod 201 to rotate, thereby moving the first movable frame 3. The second drive motor 302 drives the second threaded rod 301 to rotate, thereby moving the second movable frame 4. The third drive motor 402 drives the third threaded rod 401 to rotate, thereby moving the third movable frame 5. The movement directions of the first movable frame 3, the second movable frame 4, and the third movable frame 5 are perpendicular to each other in space, so that the mounting base 9 can move from one point to another in space within a certain range.

[0025] Please see Figures 3-5 In this embodiment, a sealing ring 904 is provided on the inner side of the mounting base 9, and the sealing ring 904 is slidably connected to the inner wall of the mounting base 9. A piston 903 is provided on the outer side of the sealing ring 904. A first air pipe 901 is provided above the mounting base 9, and the first air pipe 901 is connected to the space above the piston 903. A second air pipe 902 is provided on one side of the mounting base 9, and the second air pipe 902 is connected to the space at the bottom of the piston 903. Rotating shafts 801 are provided on both sides of the mounting base 9. A force plate 802 is provided above the rotating shaft 801. A spring 803 is provided on the side of the force plate 802 near the inner wall of the mounting base 9. A slider 905 is provided at the bottom of the piston 903. The rotating shaft 801 rotatably connects the gripping claw 8 and the force plate 802 to the mounting base 9. When gripping materials, the second air pipe 904... The air pressure at the bottom of the piston 903 increases the air intake, pushing the piston 903 upward, which in turn moves the slider 905 upward and pushes the force plate 802 to move and compress the spring 803. This causes the mounting base 9 to rotate around the axis of the rotating shaft 801 to clamp the material. After the material is transferred to the position, the air pressure above the piston 903 increases the air intake of the first air pipe 901, pushing the piston 903 downward. The spring 803 releases energy to push the force plate 802, causing the gripper 8 to rotate and reset, thereby releasing the material.

[0026] When the device is in use, the first drive motor 202 drives the first threaded rod 201 to rotate, thereby moving the first movable frame 3; the second drive motor 302 drives the second threaded rod 301 to rotate, thereby moving the second movable frame 4; and the third drive motor 402 drives the third threaded rod 401 to rotate, thereby moving the third movable frame 5. The movement directions of the first movable frame 3, the second movable frame 4, and the third movable frame 5 are perpendicular to each other in space, thereby allowing the mounting base 9 to move from one point to another in space within a certain range. The first mirror 702 and the second mirror 703 refract light, causing the light entering the mounting base 9 to undergo two refractions in the optical path tube 701 before entering the camera 7, thus allowing the camera 7 to obtain the field of view directly below the gripper 8. After the camera 7 acquires image information, the pick-and-place machine processing module analyzes the image and controls the operation of the first drive motor 202, the second drive motor 302, and the third drive motor 402, causing the mounting base 9 to move to the material location. The second air pipe 902 increases the air pressure in the space below the piston 903, pushing the piston 903 upward, causing the slider 905 to move upward and pushing the force plate 802 to move and compress the spring 803, causing the mounting base 9 to rotate around the axis of the rotating shaft 801 to clamp the material. When the material is transferred to the position, the first air pipe 901 increases the air pressure in the space above the piston 903, pushing the piston 903 downward. The spring 803 releases energy to push the force plate 802, causing the gripper 8 to rotate and reset, thereby releasing the material.
