Description

Technical Field

[0001] This utility model relates to the field of electronic material loading technology, specifically to a device capable of loading SMT materials of different diameters. Background Technology

[0002] In surface mount technology (SMT) production, electronic components are typically transported in the form of carrier reels (SMT reels, hereinafter referred to as "reels") during warehousing, handling, and loading. Most common reel-carrying devices use a central post passing through the center hole of the reel for positioning and constraint: 1. Using the central post / cone as a reference, it enables rapid assembly of reels of a single size (commonly 7 inches); 2. By replacing positioning posts of different diameters or adding collars to the central post, it can accommodate reels of different diameters.

[0003] However, the above solution has the following drawbacks: difficulty in automated alignment: the center hole has dimensional tolerances, chamfers / burrs, and positional deviations; the robot or AGV is prone to jamming and scratches during the insertion action, affecting the cycle time and stability. Poor versatility: diameter switching requires replacing the central component or adding a transition component, making debugging complicated; insufficient support for 10 / 13 / 15-inch large disks, and prone to shaking under transportation vibration; Stacking / integration between preceding and following processes is not user-friendly: the protruding central column takes up space, affecting the accessibility and field of view of actions such as labeling, scanning, visual recognition, and loading and unloading; the same carrier is difficult to carry out the entire process of "warehousing - handling - loading". ESD and surface damage risks: The center insertion causes the contact to be concentrated on the edge of the hole and the hub, resulting in uneven force distribution, which is detrimental to the long-term use of the tray.

[0015] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0016] like Figures 1-4 As shown, this embodiment of a device capable of loading SMT materials of different diameters includes a base frame 1, an eccentric cross-shaped guide rail 2 mounted on the base frame 1, a material tray 4 mounted in the middle of the guide rail 2, and a thickness-adaptive pad 7 mounted on the outer wall of the material tray 4. Adjustable column assemblies 3 are mounted on the guide rail 2 along the length and width of the base frame 1, respectively. The adjustable column assembly 3 includes a column rod 301, a slider 302, and a locking element 303. There is one adjustable column assembly 3 along the length of the base frame 1 on the guide rail 2, and two adjustable column assemblies 3 are symmetrically mounted along the width of the base frame 1 on the guide rail 2. The three adjustable column assemblies 3 are at a 120° angle to each other. A diameter setting and a scale 5 are also mounted on the upper side of the guide rail 2 along the length of the base frame 1. 7 / 10 / 13 / 15 inch markings and millimeter graduations are provided on the guide rail 2 and the column rod 301 for independent adjustment or calibration. With the cooperation of guide rail 2 and diameter setting and scale 5, the material tray 4 is free from center insertion during use, making self-centering smoother. The three-point encirclement positioning of the outer edge avoids the center hole tolerance / burr problem, significantly reducing the jamming rate and making it friendly to automatic loading and unloading of robots / AGVs. The four corners of the base frame 1 are equipped with automation interfaces 8 between the guide rails 2. The automation interfaces 8 include positioning interfaces 801, gripping holes 802 and vision ID 803. With the action of automation interfaces 8, the device is accessible throughout the entire process during use, without the obstruction of the center column, which facilitates labeling, barcode scanning, visual inspection and mounting. It realizes the integrated material string carrier through the front / back process. At the same time, the interfaces are standardized, with complete interfaces such as 3-2-1 positioning, gripping holes 802, vision reference, and RFID position, which are easy to integrate with existing conveying, buffering, loading machines and vertical storage systems. The guide rail 2 is also equipped with an upper anti-drop component 6 on the outside of the material tray 4, and shock-absorbing guide components 9 are also installed at the four outer corners of the base frame 1.

[0017] like Figures 1-4As shown, in this embodiment, the slider 302 is slidably mounted on the guide rail 2, the column rod 301 is mounted on the top of the slider 302, and the locking member 303 is mounted between the slider 302 and the guide rail 2. The locking member 303 is mainly a bolt. At the same time, the contact part between the column rod 301 and the outer periphery of the tray 4 is also equipped with an end arc surface contact pad made of ESD dissipative elastomer material. The upper anti-detachment component 6 includes a connecting bolt 601 and a flip-limiting beam 602. The flip-limiting beam 602 is mounted on the guide rail 2 through the connecting bolt 601. The flip-limiting beam 602 and the connecting bolt 601 are rotatably engaged. The lower side of the flip-limiting beam 602 is also equipped with an elastic ring.

[0018] like Figures 1-4 As shown, in this embodiment, the base frame 1 is made of aluminum profile / magnesium-aluminum alloy / carbon fiber composite material. The base frame 1 is provided with an external reference surface and reinforcing ribs. The thickness-adapting pad 7 is made of TPU / EPDM / PU foam material. The thickness-adapting pad is set with replaceable / liftable support pads for material strip widths of 8 / 12 / 16 / 24 / 32mm to ensure the stability of the material tray 4 in terms of cross-section and posture.

[0019] like Figures 1-4 As shown, in this embodiment, the positioning interface 801 is installed on one end of the guide rail 2, and the gripping holes 802 are set at the four corners of the base frame 1. The gripping holes 802 are for mechanical fingers or manual handling. The visual ID 803 is installed on the base frame 1 on one side of the gripping holes 802. The bottom surface of the positioning interface 801 is provided with 2 conical holes + 1 side positioning surface or 2 cylindrical pins + side positioning. The visual ID Fiducial visual reference point and RFID / QR code position facilitate identification and traceability. The shock-absorbing guide 9 is a guide composed of a bottom elastic pad and a front flared mouth. The shock-absorbing guide 9 is mainly used to improve the fault tolerance of loading / unloading.

[0020] The specific implementation process of this embodiment is as follows: When limiting the material tray 4, the operator moves the three columns synchronously towards the center along the guide rail 2 until the arc-shaped pad on the column rod 301 makes light contact with the outer edge of the material tray 4, or pushes the column independently to the calibrated scale according to the diameter position and locks it. The three points encircle each other to form an equidirectional constraint, achieving centering and preventing detachment. Then, the flipping limiting beam 602 is placed to form an axial limit, which, together with the shock absorption, suppresses the jumping caused by transportation vibration. Then, the bottom surface 3-2-1 interface at the positioning interface 801 is used to connect with the visual reference for upstream / downstream equipment docking. The gripping hole 802 is used for the robot / AGV lifting claw to grasp. There are no central columns around it, making labeling, scanning, visual inspection, and feeding smoother. After the positioning interface 801 is connected, the material tray 4 can be quickly limited. Due to the action of this device, there is no central insertion, self-centering is smoother, and the three points encircle the outer edge for positioning, avoiding the tolerance of the central hole. The design addresses burr issues, significantly reducing jamming rates and facilitating automated loading and unloading by robots / AGVs. It's multi-functional, with rapid diameter switching and two adjustment modes (linkage / position) to accommodate 7 / 10 / 13 / 15-inch and adjacent sizes, minimizing fixture changes and downtime. It also offers superior transport safety and vibration resistance. The three-column design, plus a top limiter, provides multi-faceted constraints (surface, line, point), preventing shaking and drops, making it suitable for cross-area handling and automated warehouse buffering. Furthermore, it offers full-process accessibility with no central column obstruction, facilitating labeling, barcode scanning, visual inspection, and machine clamping, enabling integrated material carriers to connect upstream and downstream processes. The curved, soft-surface coating distributes stress evenly, reducing edge wear. Material and grounding design meet ESD standards for electronic manufacturing. Finally, standardized interfaces include 3-2-1 positioning, 802 gripping holes, visual reference, and RFID tags, facilitating integration with existing conveyor, buffer, loading, and automated warehouse systems.
