Description

Technical Field

[0001] This utility model relates to the field of tape and reel machine technology, specifically to a tape and reel machine based on flexible vibration feeding. Background Technology

[0002] Chip taping machines are used in the front-end packaging processes of LEDs, IC chips, semiconductor chips, sensor electronic devices, etc. Their working principle involves peeling the incoming material from the blue film, then using a vibratory feeder and vibrating track to place the chip onto a carrier tape, thus completing the taping process. Existing vibratory feeders rely on customized tracks based on the component shape; changing components requires replacing the vibratory feeder or adjusting the structure, resulting in poor compatibility and high costs. Furthermore, in crystal oscillator taping, irregularly shaped metal parts are prone to jamming during production, and the accuracy of LED bead polarity identification and crystal oscillator direction calibration is insufficient, thus affecting processing efficiency.

[0003] Later, a device and its working method for chip taping or tray placement after appearance inspection were invented, with publication number CN115140364A. The device includes a lower frame, upper cover, lower plate mechanism, upper plate mechanism, flexible feeding device, multiple CCD positioning and detection systems, gantry-type robotic arm, defective product collection device, tape feeding mechanism, sealing mechanism, carrier tape feeding mechanism, carrier tape winding mechanism, tray conveyor belt moving mechanism, and tray lifting mechanism. However, this device has a complex structure, is large-scale, occupies space, and has high investment costs. Furthermore, the factory environment is often dimly lit, and the camera's image position is unclear in low light, severely affecting the judgment results, thus impacting the accuracy of the controller and product quality. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a tape feeding machine based on flexible vibration feeding, which has a simple structure, low investment cost, and improved product quality.

[0005] The technical solution adopted to achieve the purpose of this utility model is:

The third industrial camera is mounted on the conveyor belt of the roll material unloading mechanism and is used to detect whether the material and the carrier belt are in place. The outputs of the first, second, and third industrial cameras are electrically connected to the input of the controller. Each of the first, second, and third industrial cameras is equipped with a supplementary lighting mechanism, and the input of the supplementary lighting mechanism is electrically connected to the output of the controller.

[0007] Furthermore, a storage device is provided on one side of the flexible vibrating plate. The storage device is connected to the flexible vibrating plate and is higher than the flexible vibrating plate. The storage device includes a vibrator and a hopper. The hopper is located directly above the vibrator. A horizontally arranged baffle assembly is provided inside the hopper. A certain gap is left between the baffle assembly and the hopper to facilitate the passage of materials.

[0008] Furthermore, it also includes a dust collection mechanism, which includes a retractable corrugated tube and a suction cup. The retractable corrugated tube is connected to the suction cup, and the suction cup is located at the output end of the roll material discharge mechanism.

[0009] Furthermore, the material handling mechanism includes an X-axis drive mechanism, a Y-axis drive mechanism, and a Z-axis drive mechanism. The worktable of the frame is provided with symmetrically arranged Y-axis supports and linear guides. The Y-axis drive mechanism is mounted on the frame via the Y-axis supports. The movable end of the Y-axis drive mechanism is connected to the X-axis support. The X-axis drive mechanism is vertically mounted on the Y-axis drive mechanism via the X-axis support. The lower end of the X-axis drive mechanism is slidably engaged with the linear guides. The movable end of the X-axis drive mechanism is mounted with a Z-axis support. The Z-axis drive mechanism is vertically mounted on the X-axis drive mechanism via the Z-axis support. The movable end of the Z-axis drive mechanism is mounted with the rotary stepper motor.

[0010] Furthermore, the roll material feeding mechanism includes a tape conveying mechanism, a tape feeding mechanism, a tape sealing mechanism, and a tape winding mechanism. The tape feeding mechanism and the tape winding mechanism are respectively provided at both ends of the tape feeding mechanism. The tape sealing mechanism is provided above the tape feeding mechanism. The tape sealing mechanism is used to seal and press the product on the tape feeding mechanism. The tape conveying mechanism is used to convey the carrier tape onto the tape feeding mechanism. The tape winding mechanism is used to wind up the sealed product.

[0011] Furthermore, the supplementary lighting mechanism includes a first supplementary lighting mechanism, a second supplementary lighting mechanism, and a third supplementary lighting mechanism. The first supplementary lighting mechanism is correspondingly disposed on the first industrial camera, and the second supplementary lighting mechanism is correspondingly disposed on the second industrial camera.

[0014] The above technical solution has the following beneficial effects:

[0015] This invention utilizes a flexible vibrating disc to disperse and tumble materials. A first industrial camera captures the material's position within the vibrating disc, while a second industrial camera captures the position of the grasped material. This facilitates control of the material handling mechanism, allowing for adjustment of the suction nozzle angle and ensuring accurate placement of the material into the tape. A third industrial camera detects whether the material is properly positioned, and checks for any issues such as polarity, flipping, or missing material. A supplementary lighting mechanism ensures clear positional information for all three industrial cameras, improving detection accuracy. The structure is simple, reducing investment costs. The first industrial camera also allows for the inspection of the storage device for defective materials, enabling the removal of substandard materials and ensuring that no defective materials subsequently enter the flexible vibrating disc.

[0016] The flexible vibrating plate is also provided with a storage device on one side. The storage device is equipped with a baffle assembly that is movably set. The distance between the baffle assembly and the hopper of the storage device can not only screen materials that do not conform to the size in the initial screening, but also prevent a large amount of material in the storage device from entering the flexible vibrating plate and causing material overlap.

[0017] It also includes a dust collection mechanism, which facilitates the removal of dust and ensures that the materials are free of dust.

[0018] This invention is applicable to QFN chip packaging, hardware parts, hardware springs, conductive copper sheets and surface mount jumpers, and has a wide range of applications.

The retractable corrugated tube is connected to the suction cup, which is located at the output end of the roll material discharge mechanism.

[0037] The working principle of this utility model:

[0038] Materials are manually placed into a flexible vibratory feeder, which disperses and flips the materials. First, a first industrial camera detects the coordinates of each material within the feeder and identifies any defective materials, thus filtering out unqualified items. This ensures that no defective materials enter the feeder afterward, and the data is sent to a controller. The controller, based on the material coordinates received from the first camera, controls the material-grabbing mechanism to pick up the materials. After picking, a second industrial camera obtains the X, Y, and Z coordinate deviations of the material grasped by the picking mechanism. These deviations are calculated using existing industrial controller methods, and the picking mechanism adjusts the angle of its rotary stepper motors accordingly to accurately place the material onto the carrier belt. Finally, a third industrial camera checks whether the material is accurately placed onto the carrier belt, preparing it for subsequent heat sealing by the sealing mechanism. For different incoming packaging materials, adjustments to the data via a human-machine interface device broaden its applicability.
