[0024] Reference Figures 1 to 5 In this embodiment of the present invention, a high-precision automatic alignment SMT placement machine structure includes a worktable 1 and a placement table 4. A positioning base 3 for auxiliary positioning is fixedly installed on the top of the worktable 1. The placement table 4 is fixedly installed on the top of the positioning base 3. The top of the placement table 4 has symmetrically formed grooves 7, and a clamping block 8 is slidably connected to the inner side of the groove 7. A slider 9, slidably connected to the groove 7, is fixedly installed at the bottom of the clamping block 8. One end of the slider 9 is rotatably connected to a connecting rod 12, and one end of the connecting rod 12 is rotatably connected to a connecting arm 13. The bottom of the placement table 4 is fixed... A guide rod 16 is installed, and an adjusting sleeve 17 is slidably connected to the outer periphery of the guide rod 16. The two ends of the adjusting sleeve 17 are symmetrically rotatably connected to connecting rods 18. Two sets of symmetrically arranged connecting arms 13 are provided with a drive cylinder 19 in the middle. A fixing rod 15 is fixed to one end of the connecting arm 13, and one end of the fixing rod 15 is rotatably connected to the connecting rod 18. A sliding block 10 is fixedly installed at one end of the slider 9 and slidably connected to the slide groove 7. The sliding block 10 is symmetrically fixed at both ends of the slider 9. The slide groove 7 has symmetrically opened sliding grooves 11 at both ends that are adapted to slide the sliding block 10.
[0025] The above solution is adopted: the inner wall of the groove 7 at the top of the mounting stage 4 is smooth and perfectly matches the slider 9 at the bottom of the clamping block 8. The sliding blocks 10 on both sides of the slider 9 are embedded in the sliding grooves 11 at both ends of the groove 7, making the sliding more stable and precise. The connecting rod 12 and the connecting arm 13 are made of stainless steel, which is sturdy and durable. The driving cylinder 19 has strong power and can accurately control the adjusting sleeve 17 to slide along the guide rod 16, and then drive the connecting arm 13 to move through the connecting rod 18.
[0026] Reference Figures 1 to 5 One end of the connecting arm 13 is fixedly installed with a rotating shaft 14 that is rotatably connected to the positioning base 3, and the rotating shaft 14 is symmetrically fixedly installed at both ends of the connecting arm 13.
[0027] The above scheme is adopted: the connecting arm 13 is forged from high-quality alloy steel, which is hard and tough, and can withstand large external forces without easily deforming. The rotating shaft 14 is made of stainless steel and the surface is hardened to enhance wear resistance. The rotating shaft 14 is symmetrically embedded at both ends of the connecting arm 13 and cooperates with the bearing on the positioning base 3. The installation position of the rotating shaft 14 is accurate to ensure that the connecting arm 13 rotates smoothly.
[0028] Reference Figures 1 to 5 The connecting rod 12 includes a rotating rod 121 that is rotatably connected to the slider 9 and a rotating rod 122 that is rotatably connected to the connecting arm 13. The rotating rod 122 is slidably connected to the rotating rod 121. A threaded sleeve 123 is rotatably connected to the outer circumference of the rotating rod 122, and the threaded sleeve 123 is threadedly fixed to the rotating rod 121.
[0029] The above-mentioned scheme is adopted: both rotating rod 121 and rotating rod 122 of the connecting rod 12 are made of lightweight, high-strength alloy material to reduce the overall weight while ensuring sufficient strength. A high-precision bearing is installed at the connection between rotating rod 121 and the slider 9, allowing rotating rod 121 to rotate flexibly relative to the slider 9. The connection between rotating rod 122 and the connecting arm 13 also uses a high-quality bearing to ensure smooth rotation. The sliding contact surfaces of rotating rod 122 and rotating rod 121 are finely polished to ensure proper fit. The threaded sleeve 123 is tightly fitted with minimal resistance during sliding. Its threaded surface is treated with rust prevention and has high thread precision. It fits tightly with the thread of the rotating rod 121. During rotation, the relative position of the rotating rod 121 and the rotating rod 122 can be precisely adjusted. The connecting rod 12 is made of high-quality materials and the connection part is precisely designed. It rotates flexibly and slides smoothly. The length can be precisely adjusted through the threaded sleeve 123, thereby flexibly changing the position of the clamping block 8 to achieve precise clamping of different sized components, improving the adaptability and working accuracy of the SMT pick and place machine.
[0030] Reference Figures 1 to 5 The top of the workbench 1 is symmetrically fixed with support columns 20, and the top of the symmetrically arranged support columns 20 is fixedly fixed with mounting plates 21. The bottom of the mounting plates 21 is provided with connecting plates 22, and the bottom of the connecting plates 22 is fixedly fixed with gripping arm 1 23 and gripping arm 24. The top of the workbench 1 is fixedly fixed with a material feeding box 25. The top of the mounting table 4 is evenly surrounded with blind holes 6. The top of the mounting table 4 is symmetrically provided with limiters 5. The bottom of the mounting table 4 is fixedly fixed with support rods 2 for support.
[0031] The above-mentioned scheme, including gripping arm 24, gripping arm 23, and feeding box 25, is prior art as described in the comparative document, so no detailed explanation is required in this device.
[0032] The working principle of this utility model is as follows: When it is necessary to clamp the patch, the drive cylinder 19 starts to work. The action of the drive cylinder 19 will push the adjusting sleeve 17 to slide along the guide rod 16. Since the two ends of the adjusting sleeve 17 are symmetrically connected to the connecting rod 18, and the connecting rod 18 is rotatably connected to the fixed rod 15 on the connecting arm 13, the sliding of the adjusting sleeve 17 will drive the connecting rod 18 to move. The movement of the connecting rod 18 will then cause the connecting arm 13 to rotate around the rotating shaft 14. Since the connecting arm 13 is rotatably connected to the connecting rod 12, and the connecting rod 12 is rotatably connected to the slider 9, the slider 9 is fixed to the clamping block 8 and can slide in the slide groove 7 at the top of the patch table 4, so the rotation of the connecting arm 13 will be transmitted to the slider 9 through the connecting rod 12, so that the slider 9 slides in the slide groove 7. Then the clamping block 8 fixed to the slider 9 will also move with the sliding of the slider 9, thereby realizing the clamping action of the patch. When the drive cylinder 19 reverses... During the operation, the adjusting sleeve 17 slides in the opposite direction, and the clamping block 8 moves in the opposite direction, releasing the clamping of the patch. Through the combined action of the clamping block 8, the drive cylinder 19, and multiple sets of connecting parts, the patch can be assisted in positioning, reducing the error caused by vibration during machine operation, which would otherwise reduce the patch placement accuracy. At the same time, by rotating the threaded sleeve 123, since the threaded sleeve 123 is threadedly engaged with the rotating rod 121 and the rotating rod 122 is slidably connected to the rotating rod 121, the rotation of the threaded sleeve 123 will cause the rotating rod 121 to move linearly relative to the rotating rod 122. The linear movement of the rotating rod 121 changes the overall length of the connecting rod 12. Since the two ends of the connecting rod 12 are rotatably connected to the slider 9 and the connecting arm 13 respectively, the change in the length of the connecting rod 12 will affect the position of the slider 9 in the groove 7, thereby changing the position of the clamping block 8, and finally achieving the adjustment of the clamping distance.
[0033] 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.
