Description

Technical Field

[0001] This utility model relates to the field of automation technology, and more specifically, to a dual-station rotary feeding mechanism. Background Technology

[0002] Loading and unloading product components is one of the most common production processes in automated assembly. In replacing manual labor for loading and unloading, the required orientation and angle of loading and unloading vary widely. Currently, most common loading mechanisms use a one-to-one method, where a clamping end holds the component at the feeding station and then moves it to the unloading station. This method consumes a significant amount of time during the clamping end's movement, and the one-to-one approach is inefficient and does not meet market demands.

[0003] In view of this, the applicant hereby submits this application after studying the existing technology. Utility Model Content

[0026] Example 1

[0027] Depend on Figures 1 to 3As shown, this utility model embodiment provides a dual-station rotary loading mechanism, including a first rotary drive assembly 1 and a connecting plate 2 connected to its output end. A dual-station mounting base 3 is connected and disposed on the connecting plate 2. The output end of the first rotary drive assembly 1 is vertically downward and is used to drive the dual-station mounting base 3 to rotate in the vertical direction. It also includes two sets of loading modules 4 arranged parallel to each other on the dual-station mounting base 3. Each loading module 4 includes a second rotary drive assembly 5 and a clamping group 6. The output end of the second rotary drive assembly 5 is connected to the clamping group 6 and is used to drive the clamping group 6 to rotate in the vertical direction. The clamping group 6 is used to clamp the product. The first rotary drive assembly 1 is mounted on a top plate 7. The rotation shaft 9 of the first rotary drive assembly 1 is connected to the top plate 7 and the connecting plate 2. The rotation shaft 9 and the top plate 7 are connected by double bearings 8 as a rotation guide to ensure stable and reliable rotation. The first rotary drive assembly 1 controls the rotation of two sets of loading modules 4 on the dual-station mounting base 3. In one implementation, when one loading module 4 is at the feeding station, the other loading module 4 is at the discharging station, allowing for simultaneous loading and unloading. Afterward, rotating the dual-station mounting base 3 180° allows for alternating loading and unloading, thus enabling rapid and efficient simultaneous loading and unloading. Furthermore, the second rotary drive assembly 5 rotates the clamping assembly 6 to adjust the product's orientation during clamping, ensuring the product meets the directional requirements of the next station during unloading, further improving efficiency. As an auxiliary measure, detection sensors can be installed, but details are omitted here.

[0028] Preferably, the first rotary drive assembly 1 includes a rotary shaft 9, a rotating gear 10, a rack 11, and a drive cylinder 12. The rotating gear 10 is coaxially connected to the rotary shaft 9, and the rack 11 is meshed with the rotating gear 10. The drive cylinder 12 is used to drive the rack 11 to perform linear reciprocating motion. The drive cylinder 12 is fixed on the top plate 7, and the top plate 7 is provided with a sliding groove 13. The rack 11 is limited and guided by the sliding groove 13, and is driven by the drive cylinder 12 to reciprocate in the guiding direction of the sliding groove 13. Through meshing, it drives the rotating gear 10 to reciprocate, thereby driving the rotary shaft 9 to rotate.

[0029] Preferably, the second rotary drive assembly 5 includes a swing cylinder 14 and a rotating rod 15. The swing cylinder 14 is fixed on the dual-station mounting base 3. The upper end of the rotating rod 15 is connected to the output end of the swing cylinder 14, and the lower end passes through the dual-station mounting base 3. Further, the clamping assembly 6 includes a connecting block 16 and a suction cup 17. The upper end of the connecting block 16 is connected to the rotating rod 15, and the lower end is provided with a groove 18. The suction cup 17 is slidably connected to the groove 18. It also includes a spring 19, which is connected between the suction cup 17 and the groove 18. The bottom end of the suction cup 17 is used to pick up and clamp the product. In this embodiment, the swing cylinder 14 drives the rotating rod 15 to rotate, thereby driving the clamping assembly 6 below to rotate, and finally driving the product to rotate and adjust its direction. As one embodiment, the suction cup 17 can directly pick up nearby products for transfer using vacuum adsorption. Alternatively, a vertical moving mechanism (not shown in the figure) can be connected to the top plate 7 to drive the entire feeding mechanism up and down to approach or put down the product. At this time, it can work with the suction cup 17 to retract into the groove 18 to eliminate positional errors caused by parts processing or assembly, thereby improving the stability of equipment operation.

[0030] Preferably, it also includes a limiting assembly located between the top plate 7 and the connecting plate 2. The limiting assembly includes a limiting block 20 and two buffers 21. The two buffers 21 are installed below the top plate 7, located on both sides of the rotating shaft 9, and the limiting block 20 is fixed to the outer wall of the rotating shaft 9. By setting the limiting block 20 to abut against the limiter, the rotation angle of the feeding mechanism above the workstation can be positioned, ensuring the stability of the rotation. Limiting and positioning are achieved when the pistons of the limiting block 20 and the buffers 21 abut against each other. At the same time, the buffers 21 can ensure a smooth stop of movement, further providing overall stability.

[0031] Example 2

[0032] Depend on Figures 4 to 5 As shown, preferably, this embodiment provides two limiting blocks 20, which are arranged at 90° intervals on the rotating shaft 9. In this embodiment, there are two loading stations and two unloading stations. By reciprocating the two loading modules 4 at 90° intervals, a single loading mechanism can perform both online and offline loading and unloading, resulting in a small footprint and high efficiency.

[0033] Example 3

[0034] Depend on Figures 6 to 7As shown, preferably, it also includes a position moving component, which includes a left-right moving cylinder 22, a connecting seat 23, and a up-down moving unit. The left-right moving cylinder 22 is fixed on the connecting plate 2, the connecting seat 23 is connected to the output end of the left-right moving cylinder 22, and the up-down moving unit is mounted on the connecting seat 23 and connected to the dual-station mounting base 3. By setting the left-right moving cylinder 22, the horizontal stroke of the feeding module 4 can be increased to suit situations where the workstation is far away. At the same time, in this embodiment, the up-down moving unit drives the feeding module 4 to move vertically to get closer to the product part for suction and clamping.

[0035] Preferably, the vertical movement unit includes a first vertical cylinder 24 and a second vertical cylinder 25. The first vertical cylinder 24 is fixed to the connecting seat 23, and the second vertical cylinder 25 is connected to the output end of the first vertical cylinder 24. The dual-station mounting base 3 is connected to the output end of the second vertical cylinder 25. In this embodiment, the second vertical cylinder 25 drives the dual-station mounting base 3 to move up and down, allowing the loading module 4 to approach or move away from the product parts for gripping. Furthermore, the first vertical cylinder 24 increases the vertical stroke, thus adapting to situations where the loading and unloading stations are at different heights, thereby satisfying the applicability and compatibility of the mechanism.

[0036] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
