A patch structure for a chip mounter

Abstract

This utility model relates to the field of pick-and-place machine technology and discloses a pick-and-place structure for a pick-and-place machine, including a frame. This pick-and-place structure, through the setting of a calibration mechanism and a linkage mechanism, allows the electric push rod to push the top plate and the pick-and-place assembly downwards synchronously after the workpiece is moved directly below the pick-and-place suction cup. The top plate drives the mounting base, causing the round rod to slide within the vertical plate. The vertical plate moves relative to the horizontal plate, causing the calibration mechanism to move as a whole. The horizontal plate moves under the support of the moving block and the limiting frame, pushing the mounting frame to move. Calibration plates on both sides limit the front and rear sides of the workpiece, and the limiting plates limit the left and right sides of the workpiece. The setting of the telescopic spring allows the moving plate to have a certain amount of movement space under the support of the horizontal rod. When the limiting plate contacts the workpiece, the tension of the telescopic spring pushes the moving plate and the connecting rod, causing the limiting plate to restrict the position of the workpiece, thereby ensuring the accurate positioning of the workpiece.

[0023] 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.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a chip mounting structure for a chip mounter, including a frame 1, with six support legs 2 fixedly installed at the bottom of the frame 1, arranged in groups of three symmetrically front and back. A conveyor 3 is fixedly installed on the inner side of the frame 1, electrically connected to an external power source and controlled by an external program. A frame body 4 is fixedly installed between the front and rear sides of the frame 1, with an electric push rod 5 fixedly installed on the inner top wall of the frame body 4, electrically connected to an external power source and controlled by an external program. A top plate 6 is fixedly installed at the output end of the electric push rod 5, and a chip mounting assembly 9 is provided at the bottom of the top plate 6. A calibration mechanism 7 extending to the inner side of the frame body 4 is provided on the outer side of the frame body 4, and a linkage mechanism 8 connected to the calibration mechanism 7 is provided on one side of the top plate 6.

[0025] The patch assembly 9 includes a mounting rod 91, which is fixedly mounted on the bottom of the top plate 6, and a patch suction cup 92 is fixedly mounted on the bottom of the mounting rod 91.

[0026] The calibration mechanism 7 includes a limiting frame 701. Limiting frames 701 are fixedly installed on both the front and rear sides of the frame 4. A movable block 702 extending to the bottom of the limiting frame 701 is slidably installed on the inner side of the limiting frame 701. A horizontal plate 703 extending to the inner side of the frame 4 is fixedly installed on one side of the movable block 702. A mounting frame 704 is fixedly installed at the bottom of the horizontal plate 703. A crossbar 705 is fixedly installed between the left and right sides of the inner wall of the mounting frame 704. Two movable plates 706, slidably connected to the inner top wall of the mounting frame 704, are slidably installed on the outer side of the crossbar 705. A fixed mounting plate 706 is installed on one side of the movable plate 706. A telescopic spring 707 is fixedly connected to the inner wall of the mounting frame 704 and sleeved on the outside of the crossbar 705. The elastic coefficient of the telescopic spring 707 can be set according to requirements. A connecting rod 708 extending to the bottom of the mounting frame 704 is fixedly installed on one side of the moving plate 706. A limiting plate 709 that fits against the top of the conveyor 3 is fixedly installed at the bottom of the connecting rod 708. A correction plate 710 that fits against the top of the conveyor 3 is fixedly installed on the opposite sides of the front and rear mounting frames 704. The design of the limiting plate 709 and the correction plate 710 limits the four sides of the workpiece to be processed, ensuring the accuracy of the patch position.

[0027] The inner walls of the mounting frame 704 are open on both the front and rear sides. The inner bottom wall of the mounting frame 704 is provided with a limiting hole that matches the movement trajectory of the connecting rod 708. The interior of the moving plate 706 is provided with a rectangular hole that matches the crossbar 705. The two mounting frames 704 are symmetrically distributed from left to right.

[0028] The linkage mechanism 8 includes a mounting base 81. Mounting bases 81 are fixedly installed at both the front and rear ends of the top plate 6. A vertical plate 82 is fixedly installed on the top of the horizontal plate 703. A round rod 83 that passes through the vertical plate 82 is fixedly installed on the inner side of the mounting base 81.

[0029] The interior of the upright plate 82 has a slotted hole, the size of which is adapted to the moving trajectory of the round rod 83.

[0030] During use, ensure the pick-and-place machine is in a stable working state, with all components securely installed and free from looseness. Check that the conveyor 3 is working properly and can accurately transport items to the placement position. The placement suction cup 92 picks up the placement item. Turn on the power to the pick-and-place machine and start the conveyor 3 to begin transporting the item. Start the electric push rod 5, which lowers the top plate 6 and its placement assembly 9 and calibration mechanism 7. The limit plate 709 in the calibration mechanism 7 moves relative to the top plate 6 first. As the top plate 6 continues to descend, the calibration plate 710 performs final calibration on the item and places the placement item on the item in the accurate calibrated position. Then, it resets and prepares for the next placement. After placement is completed, the electric push rod 5 rises, causing the top plate 6 and its placement assembly 9 and calibration mechanism 7 to rise synchronously. The conveyor 3 continues to transport the next item to the placement position, preparing for the next placement operation. Regularly check all components of the pick-and-place machine to ensure they are in good working condition. Clean the placement suction cup 92 and calibration mechanism 7 to prevent dust and debris from affecting the placement quality. Lubricate and maintain the electric push rod 5 and conveyor 3 to extend their service life.

[0031] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0032] In summary, this placement structure for a pick-and-place machine, by setting up a calibration mechanism 7 and a linkage mechanism 8, allows the electric push rod 5 to push the top plate 6 and the placement assembly 9 to move down synchronously when the workpiece moves directly below the placement suction cup 92. The top plate 6 drives the mounting base 81, causing the round rod 83 to slide within the vertical plate 82. The vertical plate 82 moves relative to the horizontal plate 703, causing the calibration mechanism 7 to move as a whole. The horizontal plate 703 moves under the support of the moving block 702 and the limiting frame 701. The horizontal plate 703 pushes the mounting frame 704 to move. The calibration plates 701 on both sides limit the front and rear sides of the workpiece, and the limiting plates 709 limit the left and right sides of the workpiece. On both sides, the extension springs 707 allow the moving plate 706 to have a certain amount of movement space under the support of the crossbar 705. When the limiting plate 706 contacts the workpiece, the tension of the extension springs 707 pushes the moving plate 706 and the connecting rod 708, causing the limiting plate 706 to restrict the position of the workpiece, thereby ensuring the accurate position of the workpiece and achieving the purpose of calibrating the position of the limiting structure. This solves the problem that without a certain limiting structure, the pick-and-place machine generally operates at a high speed and has a high degree of automation. After the conveyor stops suddenly, there may be some slight deflection due to inertia, which cannot be calibrated in time and affects the pick-and-place operation.
