Description

Technical Field

[0001] This utility model relates to the field of automated assembly technology, specifically to an automated assembly device for precision modules. Background Technology

[0002] Precision press fitting machines are essential equipment in the automatic assembly process of precision modules, and pneumatic precision press fitting machines are the most widely used precision press fitting machines due to their low cost, fast response and simple structure.

[0003] Existing pneumatic precision press machines are mostly open-loop structures, meaning they rely solely on the air pressure setting at the air source to control the pressure. As a result, they are relatively lacking in pressure accuracy and repeatability. Moreover, during press-fitting, the supporting mold is usually placed directly below the press-fitting equipment, which can easily lead to certain safety hazards when directly picking up and placing materials. Therefore, we propose an automated assembly device for precision modules. Utility Model Content

[0006] Furthermore, the driving pressing mechanism includes a driving cylinder, a connecting frame, and a pressure plate. The driving cylinder is fixedly installed on the top of the top plate, the output end of the driving cylinder is fixedly connected to the connecting frame, the bottom of the connecting frame is fixedly connected to the pressure plate, a pressure sensor is provided between the output end of the driving cylinder and the top of the connecting frame, and a laser sensor for detecting the position of the connecting frame is fixedly connected to the bottom of the top plate.

Two sets of limiting sleeves are fixedly connected to the top plate, and a telescopic rod is slidably connected inside the limiting sleeve. The output end of the telescopic rod is fixedly connected to the connecting frame.

[0008] Furthermore, the equalization mechanism includes a connecting pipe, a pressure regulating valve, a filter, and a buffer tank. The air supply position of the drive cylinder is fixedly connected to the connecting pipe, and the pressure regulating valve, the filter, and the buffer tank are installed through the connecting pipe. The end of the connecting pipe away from the drive cylinder is fixedly connected to an external air supply device.

[0009] Furthermore, the balancing mechanism also includes a threaded sleeve, a connecting sleeve, a threaded tube, and a guide seat. The threaded sleeve is located at the top of the drive cylinder and outside the connecting tube. The bottom of the connecting sleeve is fixedly connected to a threaded tube that is threadedly connected to the threaded sleeve. The top of the connecting sleeve is fixedly connected to an arc-shaped guide seat.

[0010] Furthermore, the driving movement mechanism includes a connecting shaft, a fixed frame, a drive seat, an adjustment groove, a slide rail, a slider, and a drive rod.

[0015] 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.

[0016] Please see Figures 1-4 This utility model provides a technical solution: an automated assembly device for precision modules, including a base 1, a top plate 3 fixedly connected to the top of the base 1 by multiple sets of support rods 2, a bearing mold 7 for material bearing is provided on the top of the base 1, a driving pressing mechanism 4 for providing pressing accuracy is provided on the top plate 3, an equalization mechanism 5 for stabilizing the air supply is connected to the air supply port of the driving pressing mechanism 4, and a driving moving mechanism 6 for driving the bearing mold 7 to move is provided on the output end of the driving pressing mechanism 4 and the side wall of the bearing mold 7.

[0017] The material to be pressed is placed inside the bearing mold 7, and then the driving pressing mechanism 4 presses down to complete the pressing process. During the pressing process, the driving moving mechanism 6 can be used to move the bearing mold 7 downwards towards the driving pressing mechanism 4. When the driving pressing mechanism 4 rises, the bearing mold 7 can be moved away from the bottom of the driving pressing mechanism 4. This avoids the safety hazard of movement during loading and unloading. The equalization mechanism 5 can balance the gas supply to the driving pressing mechanism 4, and fundamentally avoid the decrease in pressure accuracy caused by air pressure fluctuations.

[0018] Please see Figures 1-4The driving pressing mechanism 4 includes a driving cylinder 8, a connecting frame 11, and a pressure plate 12. The driving cylinder 8 is fixedly installed on the top of the top plate 3. The output end of the driving cylinder 8 is fixedly connected to the connecting frame 11. The bottom of the connecting frame 11 is fixedly connected to the pressure plate 12. A pressure sensor 13 is provided between the output end of the driving cylinder 8 and the top of the connecting frame 11. A laser sensor 14 for detecting the position of the connecting frame 11 is fixedly connected to the bottom of the top plate 3. The driving pressing mechanism 4 also includes a limiting sleeve 9 and a telescopic rod 10. Two sets of limiting sleeves 9 are fixedly connected on the top plate 3. The telescopic rod 10 is slidably connected inside the limiting sleeve 9. The output end of the telescopic rod 10 is fixedly connected to the connecting frame 11.

[0019] The drive cylinder 8 drives the connecting frame 11 and the pressure plate 12 downward to complete the pressing work. The pressure sensor 13 can provide real-time feedback of actual pressure data. The controller can make fine adjustments based on the actual measured pressure value to further improve the pressure control accuracy. The laser sensor 14 can be used to locate and assist the device when it returns to the standby position after completing a pressing action. This avoids the pressing position shifting due to the accuracy of the standby position after repeated work, which would affect the pressing accuracy.

[0020] Please see Figures 1-4 The balancing mechanism 5 includes a connecting pipe 15, a pressure regulating valve 16, a filter 17, and a buffer tank 18. The air supply position of the drive cylinder 8 is fixedly connected to the connecting pipe 15. The pressure regulating valve 16, the filter 17, and the buffer tank 18 are installed through the connecting pipe 15. The end of the connecting pipe 15 away from the drive cylinder 8 is fixedly connected to an external air supply device. The balancing mechanism 5 also includes a threaded sleeve 19, a connecting sleeve 20, a threaded pipe 21, and a guide seat 22. The threaded sleeve 19 is installed at the top of the drive cylinder 8 and outside the connecting pipe 15. The bottom of the connecting sleeve 20 is fixedly connected to the threaded pipe 21, which is threaded to the threaded sleeve 19. The top of the connecting sleeve 20 is fixedly connected to the arc-shaped guide seat 22.

[0021] The connecting pipe 15 is connected to the external air supply device, and the buffer tank 18 can buffer the air pressure at the initial stage to avoid the direct impact of pressure fluctuations at the air source. The filter 17 can filter impurities in the compressed air to prevent impurities from entering the stamping structure and affecting the operation of the equipment. Finally, the gas passes through the pressure stabilizing valve 16 to stabilize the air source, thereby improving the pressure accuracy of the pneumatic precision press machine from the source. The arc-shaped guide seat 22 can guide the connecting pipe 15 when it is pulled, preventing the connecting pipe 15 from bending and affecting the gas delivery.

[0022] Please see Figures 1-4The driving moving mechanism 6 includes a connecting shaft 23, a fixed frame 24, a driving seat 25, an adjusting groove 26, a slide rail 27, a slider 28, and a driving rod 29. The top of the base 1 is fixedly mounted with the slide rail 27, which is slidably connected to the bearing mold 7 via the slider 28. The side wall of the bearing mold 7 is fixedly connected with the connecting shaft 23. The top of the base 1 is rotatably connected with the "L"-shaped driving seat 25 via the fixed frame 24. The fixed frame 24 and the driving seat 25 are connected by a torsion spring. The driving seat 25 is provided with an adjusting groove 26 at the position corresponding to the connecting shaft 23 for sliding engagement of the connecting shaft 23. The bottom of the connecting frame 11 is fixedly connected with the driving rod 29 that contacts the top of the driving seat 25. A connecting rod 30 is fixedly connected between the two sets of driving seats 25.

[0023] The torsion spring between the fixed frame 24 and the drive seat 25 allows the bearing mold 7 to be located on one side of the connecting frame 11. When the drive cylinder 8 works, it drives the drive rod 29 to descend, which can then press the "L"-shaped drive seat 25 to rotate along the fixed frame 24. The adjustment groove 26 on the "L"-shaped drive seat 25 can correspond to the connecting shaft 23. As the drive seat 25 rotates, it can drive the bearing mold 7 to move under the pressure plate 12 via the slide rail 27 and the slider 28 for the pressing step.

[0024] In use, firstly, the material to be pressed is placed inside the bearing mold 7. Then, the driving pressing mechanism 4 presses down to complete the pressing process. During pressing, the driving moving mechanism 6 can move the bearing mold 7 downwards towards the driving pressing mechanism 4. When the driving pressing mechanism 4 rises, the bearing mold 7 is moved away from below the driving pressing mechanism 4, thus avoiding safety hazards caused by movement during loading and unloading. The balancing mechanism 5 balances the gas supply to the driving pressing mechanism 4, preventing pressure accuracy loss due to air pressure fluctuations. The driving cylinder 8 drives the connecting frame 11 and the pressure plate 12 downwards to complete the pressing work. The pressure sensor 13 provides real-time feedback of actual pressure data, and the controller makes fine adjustments based on the measured pressure value to further improve pressure control accuracy. The laser sensor 14 assists in resetting after each pressing action, ensuring a precise return to the standby position. This prevents the pressing position from shifting due to repeated work and affecting pressing accuracy. The connecting pipe 15 connects to the external air supply device. The system features a buffer tank 18 for initial air pressure buffering, preventing direct impact from pressure fluctuations at the air source. A filter 17 filters impurities from the compressed air, preventing them from entering the pressing structure and affecting equipment operation. Finally, the gas passes through a pressure regulating valve 16 to stabilize the air source, improving the pressure accuracy of the pneumatic precision press-fitting machine from the source. An arc-shaped guide seat 22 guides the connecting pipe 15 when it is under tension, preventing bending and ensuring proper gas delivery. A torsion spring between the fixed frame 24 and the drive seat 25 keeps the bearing mold 7 positioned within the connecting... On one side of the receiving frame 11, when the drive cylinder 8 works, it drives the drive rod 29 to descend. At this time, it can press the "L"-shaped drive seat 25 to rotate along the fixed frame 24. The adjustment groove 26 opened on the "L"-shaped drive seat 25 can correspond to the connecting shaft 23. As the drive seat 25 rotates, it can drive the bearing mold 7 to move to the bottom of the pressure plate 12 through the slide rail 27 and the slider 28 for the pressing step. After the pressing is completed, the drive cylinder 8 drives the drive rod 29 to rise, the torsion spring resets the drive seat 25, and then pulls the bearing mold 7 away from the bottom of the pressure plate 12, so as to facilitate the safe handling of materials.
