[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0018] It should be noted that when a component is described as "fixed to" another component, it can be directly on the other component or may have a component in between. When a component is considered "connected to" another component, it can be directly connected to the other component or may have a component in between. When a component is considered "set on" another component, it can be directly set on the other component or may have a component in between. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] As attached Figure 1 Appendix Figure 2 The diagram shows the loading device of the chip mounter of this invention, including a transfer platform 1. A conveyor belt 2 is installed on one side of the transfer platform 1, and a linear drive device 3 is located on the other side of the transfer platform 1. The linear drive device 3 includes a vertically mounted rail 31 and a first slider 32 slidably connected to the rail 31. A loading tray 4 for carrying stacked circuit boards is connected to the first slider 32. A rotary motor 5 is installed on the transfer platform 1. A horizontal connecting rod 6 is connected to the output end of the rotary motor 5. The center of the connecting rod 6 is connected to the output end of the rotary motor 5. Cylinders 7 are installed at both ends of the connecting rod 6, and suction cups 8 are installed at the output ends of the cylinders 7. The suction cups 8 reciprocate vertically under the drive of the cylinders 7, and the connecting rod 6 rotates horizontally by 180° under the drive of the rotary motor 5. The suction cups 8 pick up the circuit boards on the loading tray 4 and transfer them to the conveyor belt 2. During the picking process, the cylinders 7 push the suction cups 8 downwards to the circuit board closest to the top of the loading tray 4. Then, the cylinders 7 retract, causing the suction cups 8 to rise vertically, preventing other directional movement that could scratch the circuit boards below.

[0020] A sensor is installed on one side of the linear drive device 3. The sensor is used to detect the height of the material on the feeding tray 4. After the suction cup 8 removes the material at the top, it drives the first slider 32 to move upward so that the material at the top of the feeding tray 4 is kept at the same height so that the suction cup 8 can pick it up.

[0021] Adjusting blocks 9 are installed at both ends of the connecting rod 6. The adjusting blocks 9 are horizontally slidably connected to the connecting rod 6. Several through holes 61 are machined on the connecting rod 6, and mounting holes are machined on the adjusting blocks 9. The connecting rod 6 and the adjusting blocks 9 are fixedly connected by fasteners that pass through the through holes 61 and enter the mounting holes. The cylinder 7 is connected to the bottom of the adjusting block 9 so as to adjust the horizontal distance between the cylinder 7 and the rotary motor 5, so that the suction cup 8 can contact the appropriate position on the circuit board to achieve a better suction effect, so as to prevent the circuit board from falling off midway. The falling position of the suction cup can be adjusted according to the different specifications of the circuit board, thereby improving the flexibility and applicability of the device.

[0022] A guide rail 10 and a second slider 11 vertically slidably connected to the guide rail 10 are mounted on one side of the pallet. The guide rail 10 is close to the linear drive device 3 to avoid interference with the connecting rod. The second slider 11 is connected to the loading pallet 4, making the vertical movement of the loading pallet 4 more stable and less prone to tilting. The second slider 11 is machined with a horizontal groove, and the side of the loading pallet 4 is embedded in the groove, allowing the second slider 11 and the loading pallet 4 to move horizontally, so as to adjust the position of the guide rail 10 as needed to achieve a better stability effect.

[0023] The feeding device also includes a support frame 12, a linear drive device 3 and a guide rail 10 mounted on the support frame 12, making the overall structure more stable.

[0024] The feeding device of this utility model pick and place machine separates and transfers stacked circuit boards, transporting the circuit boards to the area to be placed, thereby improving the feeding efficiency and making the feeding process more orderly and stable.

[0025] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
