BRIEF DESCRIPTION OF DRAWINGS

[0015] Figure 1 It is a structural schematic view of the utility model. DETAILED DESCRIPTION

[0016] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0017] Please see Figure 1 This utility model provides a miniature spring alignment mechanism, including: an X-axis transport module 1, a spring alignment mechanism 2 disposed above one end of the X-axis transport module 1, and a lifting mechanism 3 disposed below the X-axis transport module 1. The lifting mechanism 3 is correspondingly disposed below the spring alignment mechanism 2. A tray is movably placed on the moving end of the X-axis transport module 1. The tray is provided with a plurality of slots for placing springs. The spring alignment mechanism 2 has a built-in magnet.

[0018] During operation, the position corresponding to the lower part of the spring alignment mechanism 2 is designated as the first station of the X-axis transport module 1, and the position of the X-axis transport module 1 away from the spring alignment mechanism 2 is designated as the second station. When the moving end of the X-axis transport module 1 moves to the second station, the tray loaded with springs is placed on the X-axis transport module 1 for transport. The tray is moved to the first station by the X-axis transport module 1, and then the lifting mechanism 3 lifts the tray, bringing it close to the spring alignment mechanism 2. Since the spring alignment mechanism 2 has a built-in magnet, the springs loaded in the tray are attracted to the spring alignment mechanism 2 by the magnet. Because the tray has several slots, the position of the springs can be defined by the slots, so that the orientation of the springs meets the requirements of robot picking. Then, the springs are removed from the tray by the spring alignment mechanism 2 with the built-in magnet, so that the orientation of the springs attracted to the spring alignment mechanism 2 is the same as that in the tray, which facilitates the robot to pick up the springs from the spring alignment mechanism 2 and ensures the consistency of the spring position during picking.

[0019] In some embodiments, the spring realignment mechanism 2 includes: a flip drive motor 21, a flip arm 22 connected to the output end of the flip drive motor 21, and a spring realignment plate 23 disposed on the flip arm 22, wherein the magnet is disposed inside the spring realignment plate 23. When the flip drive motor 21 is started, the flip arm 22 rotates along with the start of the flip drive motor 21, thereby flipping the spring realignment plate 23 180°. When picking up a spring from the tray, the spring realignment plate 23 faces downward to facilitate the picking up of the spring from the tray by the built-in magnet. After the picking is completed, the lifting mechanism 3 resets, the tray descends, and the flip drive motor 21 is started at the same time, so that the spring realignment plate 23 faces upward, so that the robot can pick up the spring from the spring realignment plate 23 for assembly work.

[0020] In some embodiments, a scraping mechanism 4 is provided above the spring straightening mechanism 2. The scraping mechanism 4 includes: a scraping drive motor 41, a scraping transmission mechanism 42 connected to the output end of the scraping drive motor 41, a scraping slider 43 connected to the output end of the scraping transmission mechanism 42, and a scraping block 44 connected to the scraping slider 43. The scraping block 44 is L-shaped. The scraping drive motor 41 drives the scraping slider 43 to reciprocate through the scraping transmission mechanism 42, so that the bottom surface of the scraping block 44 passes over the spring straightening mechanism 2 and has a clearance distance between it and the spring straightening mechanism 2. When the spring straightening plate 23 picks up the springs, the picked-up springs may overlap or cluster. By activating the scraping drive motor 41, the scraping plate moves back and forth, thereby cleaning up the abnormal springs to meet the needs of the robot for picking. The clearance between the bottom surface of the scraper block 44 and the spring alignment plate 23 is slightly larger than the maximum outer diameter of the spring, so as to prevent the qualified spring from shifting during the movement of the scraper block 44.

[0021] In some embodiments, the bottom cross-section of the scraper block 44 is a triangle or trapezoid with slopes on both sides, so as to facilitate pushing the overlapping or clustered springs and avoid interference during the scraping process.

[0022] In some embodiments, the scraper block 44 has a slotted hole 441 along its vertical direction, and the scraper slider 43 has a threaded hole corresponding to the slotted hole 441. A screw passes through the slotted hole 441 and is locked into the threaded hole, thereby fixing the scraper block 44 onto the scraper slider 43. By changing the relative position between the slotted hole 441 and the threaded hole when the locking screw is tightened, the height of the scraper block 44 can be adjusted to meet the scraping requirements of spring materials of different specifications.

[0023] In some embodiments, the lifting mechanism 3 includes: a lifting drive motor 31, a lifting screw 32 connected to the output end of the lifting drive motor 31, a lifting slider 33 sleeved on the lifting screw 32, a lifting bracket 34 connected to the lifting slider 33, and a lifting block 35 disposed on the lifting bracket 34. The lifting bracket 34 is U-shaped, and lifting blocks 35 are respectively disposed on the top of both sides of the U-shaped lifting bracket 34. The lifting blocks 35 are respectively located on both sides of the X-axis transport module 1. The lifting drive motor 31 drives the lifting slider 33 to move up and down through the lifting screw 32. When it is necessary to lift the tray, the lifting drive motor 31 is activated, causing the lifting screw 32 to rotate, thereby driving the lifting slider 33 to move up and down along the lifting screw 32, thereby pushing the lifting block 35 to move upward. As the lifting block 35 moves upward, it moves upward from both sides of the X-axis transport module 1 and contacts the bottom edge of the tray, thereby lifting the tray upward and bringing it close to the spring alignment plate 23. The magnets built into the spring alignment plate 23 then attract the spring in the tray. After the spring is transferred to the spring alignment plate 23, the lifting drive motor 31 starts in reverse, causing the lifting slider 33 to move downward along the lifting screw 32, thus placing the empty tray on the X-axis transport module 1 for easy delivery via the X-axis transport module 1.

[0024] In some embodiments, a positioning mechanism 5 is provided at the end of the X-axis transport module 1 away from the spring-aligning mechanism 2. The positioning mechanism 5 includes: a front positioning block 51 disposed beside the X-axis transport module 1, and left and right positioning modules 52 disposed on both sides of the X-axis transport module 1. The front positioning blocks 51 are respectively disposed on both sides of the X-axis transport module 1. The left and right positioning modules 52 include: a positioning drive assembly 521 disposed below the X-axis transport module 1, a positioning arm 522 connected to the output end of the positioning drive assembly 521, and left and right positioning blocks 523 disposed on the positioning arm 522. The positioning drive assembly 521 drives the two sets of positioning arms 522 to move closer to or further away from the X-axis transport module 1. When the X-axis transport module 1 moves the tray to the second station, the front end of the tray contacts the front positioning block 51, restricting the movement of the tray. Then, the positioning drive component 521 drives the left and right positioning blocks 523 to move towards the tray, centering the tray from the left and right. After positioning, the X-axis transport module 1 moves the tray to the first station. The centering of the tray by the positioning mechanism 5 ensures that the lifting mechanism 3 can stably lift the tray when the X-axis transport module 1 delivers it to the first station, preventing tray misalignment from affecting the lifting effect.

[0025] In some embodiments, the positioning drive assembly 521 employs two sets of drive cylinders facing opposite directions. By simultaneously driving the left and right positioning blocks 523 in opposite directions with the two sets of drive cylinders, the tray on the X-axis transport module 1 is positioned in the center.

[0026] In some embodiments, the positioning drive component 521 employs a two-claw pneumatic finger. The two-claw drive cylinders simultaneously drive the left and right positioning blocks 523 to move in opposite directions, thereby centering the tray on the X-axis transport module 1. Compared to using two sets of drive cylinders, using a two-claw pneumatic finger improves the stability of the synchronous movement of the left and right positioning blocks 523 on both sides, avoiding any impact on the centering effect of the tray due to differential movement of the left and right positioning blocks 523 on both sides.

[0027] In summary, this invention uses an X-axis transport module to move the tray to the corresponding position of the spring alignment mechanism, and then a lifting mechanism to lift the tray, bringing it close to the spring alignment mechanism. Since the spring alignment mechanism has a built-in magnet, the magnetism attracts the springs loaded in the tray to the mechanism. Because the tray has several slots, the position of the springs can be defined, ensuring the springs' orientation meets the robot's picking requirements. The spring alignment mechanism, with its built-in magnet, then removes the springs from the tray, ensuring that the springs adsorbed on the alignment mechanism have the same orientation as in the tray. This facilitates the robot's picking of the springs from the alignment mechanism, ensuring consistency in spring position during pickup.

[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
