Description

Technical Field

[0001] This utility model relates to the field of electronic component taping and reeling equipment technology, specifically to a fully automatic taping and reeling machine. Background Technology

[0002] With the rapid development of electronic products, the demand for electronic components is constantly growing. In order to meet the requirements of surface mount technology, traditional through-hole component packaging is gradually being replaced by surface mount packaging. Typically, various electronic components need to be taped and reeled by a tape and reel machine for subsequent automated production and assembly. Existing fully automatic tape and reel machines mainly rely on circular vibrating discs and linear vibrating tracks to achieve automatic feeding, which has improved production efficiency to a certain extent. However, for electronic components with high appearance requirements, existing technology has certain limitations.

[0003] The shortcomings of existing technology: 1. Incomplete inspection: Existing fully automatic tape and reel machines can only inspect the top surface of electronic components through the upper vision system, and cannot inspect the bottom surface of the components. As a result, electronic components with scratches on the back and damaged corners may be mixed into good products, reducing the yield of finished products.

[0004] 2. Limitations of feeding methods: Existing technologies mostly use vibratory feeders and linear vibrating tracks for feeding. This method is prone to collisions or damage when processing components with high appearance requirements, and is not suitable for electronic components with high quality requirements.

[0005] 3. Insufficient scope of application: Existing fully automatic tape and reel machines are often dedicated to specific purposes, and can only handle components of a single model or shape. They lack versatility and are inefficient when switching between different products.

[0006] 4. Low changeover efficiency: Due to the lack of a universal pallet structure in existing equipment, product model conversion takes a long time, which affects production efficiency.

[0007] 5. Inadequate management of defective products: Some existing equipment lacks a dedicated module for placing defective products, which may result in defective products being mixed with good products, increasing the difficulty of subsequent sorting.

[0008] Therefore, existing technologies have shortcomings and need further improvement. Utility Model Content

[0013] Furthermore, the universal tray has a flat plate structure with multiple receiving slots for placing components arranged in a matrix on it.

[0014] Furthermore, the three-axis material handling module includes X-axis, Y-axis and Z-axis motion mechanisms arranged perpendicularly to each other; Used to drive the multiple pick-up nozzles to move in three-dimensional space to transfer components between the general tray, the lower CCD module, the defective product placement position and the tape module; The Z-axis is set on the Y-axis, the Y-axis is set on the X-axis, and the material suction nozzle is set on the Z-axis. The Z-axis is used to drive the material suction nozzle to move up and down, while the X-axis and Y-axis are used to drive the material suction nozzle to move horizontally.

[0015] Furthermore, each of the plurality of pick-up nozzles is connected to an independent rotary drive mechanism, so that each pick-up nozzle can rotate around its axis, thereby adjusting the orientation of the picked-up component.

[0016] Furthermore, the upper CCD module is positioned above the material picking position and is used to detect and position the upper surface of the component before it is picked up.

[0017] Furthermore, the lower CCD module includes an upward-facing camera positioned below the movement path of the three-axis pick-up module to detect the lower surface of the component after it is picked up by the pick-up nozzle.

[0018] Furthermore, the defective product placement area is provided with a container for holding defective products; The container is located near the tape and reel module and within the working range of the triaxial material handling module, and is used to collect components that are determined to be defective by the lower CCD module.

[0019] Furthermore, the tape-tapping module includes a carrier tape conveying mechanism and a cover tape sealing mechanism, wherein the carrier tape conveying mechanism is used to convey a carrier tape with multiple tape cavities; The carrier tape is placed on the carrier tape reel, and the cover tape is placed on the cover tape reel; The cover tape sealing mechanism is used to seal the cover tape onto the carrier tape by heat sealing, so as to encapsulate the component in the tape cavity of the carrier tape, and the sealed carrier tape is collected on the receiving tray.

[0021] 2. Use universal pallet feeding to avoid damage: The universal pallet, together with the adjustable conveyor line, is used to feed materials, replacing the vibratory feeder feeding method. This reduces mechanical damage to components and is especially suitable for products with high appearance requirements.

[0022] 3. Three-axis material handling module enhances flexibility: The three-axis module, in conjunction with the rotatable suction nozzle, enables flexible gripping and positioning, which not only ensures accurate placement of components but also improves the equipment's compatibility with different components.

[0023] 4. Quick changeover and improved efficiency: Due to the use of a universal tray structure, only the tray needs to be replaced when switching between different models of components, which shortens the changeover time and greatly improves production efficiency.

[0024] 5. Set up a place for defective products and make sorting clear: During the inspection process, defective products can be placed directly into a special NG place to avoid defective products being mixed into the good product belt and reduce the difficulty of subsequent sorting.

[0033] The adjustable conveyor line 2 includes two parallel conveyor rails, and the distance between the two conveyor rails is adjustable to accommodate universal pallets 3 of different sizes.

[0034] The universal tray 3 is a flat plate structure with multiple slots arranged in a matrix for placing components.

[0035] The three-axis material handling module 4 includes motion mechanisms for X-axis 11, Y-axis 12 and Z-axis 13 arranged perpendicularly to each other; Used to drive the plurality of material pick-up nozzles 10 to move in three-dimensional space to transfer components between the general tray 3, the lower CCD module 6, the defective product placement position 7 and the tape module 9; The Z-axis 13 is set on the Y-axis 12, the Y-axis 12 is set on the X-axis 11, and the material suction nozzle 10 is set on the Z-axis 13.

[0036] Each of the plurality of pick-up nozzles 10 is connected to an independent rotary drive mechanism, so that each pick-up nozzle 10 can rotate around its axis, thereby adjusting the orientation of the gripped component.

[0037] The upper CCD module 5 is positioned above the material picking position and is used to detect and position the upper surface of the component before it is picked up.

[0038] The lower CCD module 6 includes an upward-facing camera positioned below the movement path of the three-axis material handling module 4, so as to detect the lower surface of the component after it is picked up by the material handling nozzle 10.

The carrier tape conveying mechanism is used to convey a carrier tape with multiple tape cavities. The carrier tape is mounted on the carrier tape reel 15, and the cover tape is mounted on the cover tape reel 16; The cover tape sealing mechanism 14 is used to seal the cover tape onto the carrier tape by heat sealing, so as to encapsulate the component in the tape cavity of the carrier tape, and the sealed carrier tape is collected onto the receiving tray 17.

[0041] The principle of this utility model is as follows: I. System Composition and Functional Positioning The fully automatic tape and reel machine consists of seven functional units: feeding, conveying, picking, detection, sorting, packaging, and receiving. Each unit is connected in series via an adjustable conveyor line 2 to form a closed-loop logistics and information flow.

[0042] II. Work Process and Principles Feeding The material loading hopper module 1 stacks several general-purpose pallets 3 at a time, and uses a lifting / distribution mechanism to release the bottom pallet piece by piece to the entrance of the adjustable conveyor line 2, realizing unattended batch loading.

[0043] Conveying and Positioning The adjustable conveyor line 2 uses two parallel, adjustable-spacing guide rails to accommodate pallets of different sizes. After the pallet is conveyed to the picking position, it is precisely positioned by a stop / clamping mechanism to provide a reference for subsequent visual inspection and picking.

[0044] Visual inspection of upper surface The upper CCD module 5 is fixed directly above the material picking position. Before picking up the material, it takes a global picture of all components in the tray to complete the identification and coordinate positioning of defects on the upper surface, and sends the data to the control system.

[0045] Three-axis material handling and attitude adjustment The three-axis material handling module 4 (X11-Y12-Z13 gantry structure) drives multiple independently rotating material handling nozzles 10 to sequentially press down and pick up components according to the coordinates given by vision. After picking up, the nozzle can rotate around the Z-axis 13 to correct the component angle in real time and ensure that the orientation is consistent when entering the subsequent workstation.

[0046] Lower surface visual inspection The suction nozzle carries the component to the upper CCD module 6 and pauses. The upward-facing camera takes a second picture of the lower surface of the component to achieve double-sided defect detection. The system combines the detection results of the upper and lower surfaces to determine whether the product is good or defective.

[0047] Sorting Defective components are directly transferred to defective product placement area 7 (located next to tape and reel module 9) and collected in a dedicated container; good products continue to be transported to tape and reel module 9 via the nozzle.

[0048] Tape and reel packaging The carrier tape conveyor conveys the empty carrier tape to the packaging position; after the nozzle puts the good products into the carrier tape cavity in sequence, the cover tape sealing mechanism 14 uses heat to bond the cover tape to the carrier tape to complete the sealing and packaging; the packaged carrier tape is wound up by the take-up tray 17 to realize the output of finished products.

[0049] Empty pallet recycling After the components are removed, the pallet is sent to the unloading hopper module 8 by the adjustable conveyor line 2. The pallets are stacked layer by layer by the stacking mechanism to realize the automatic recycling of empty pallets, which are then picked up manually in one go to complete the cycle.

[0050] III. Core Innovation Points Dual CCD full inspection: 100% visual inspection of the upper and lower surfaces of components is carried out before and after pickup to prevent double-sided defective parts from entering the tape.

[0051] Independent rotating nozzles: Each nozzle can rotate around an axis, allowing for online adjustment of component angles at any stage of material handling, inspection, and feeding to adapt to polarity / direction requirements and improve tape consistency.

[0052] Adjustable conveyor line 2 + universal tray 3: The spacing of the conveyor rails is adjustable. Combined with the matrix-type receiving tray, it enables the co-production of multiple specifications of components. Changeover only requires software switching and simple mechanical adjustments.

[0053] Closed-loop logistics: The entire process of loading, conveying, and empty tray recycling is automated. Humans only need to load and unload the material hopper and receive the tray in batches. A single machine can achieve "lights out" operation.

[0054] In summary, this fully automatic taping machine achieves efficient, reliable, and flexible fully automatic packaging of components from bulk materials to finished taped products through the coordinated control of "vision + multi-axis servo + closed-loop logistics".

[0055] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
