Description

Technical Field

[0001] This utility model relates to the field of electronic component testing, and in particular to a device for detecting appearance defects in electronic component packaging. Background Technology

[0002] In the electronic component manufacturing industry, the packaging appearance quality of electronic components directly affects the product's market competitiveness and customer satisfaction. With the increasing miniaturization and precision of electronic products, the requirements for detecting appearance defects in electronic component packaging are also becoming increasingly stringent. Traditional electronic component packaging appearance defect detection devices mostly employ a single-station inspection method, meaning they can only inspect one item at a time, and typically require multiple loading, inspection, and unloading processes. This is not only inefficient but also increases the complexity and error of manual operation. Furthermore, traditional inspection methods often only inspect one or certain specific surfaces of the item, making it difficult to guarantee comprehensive coverage. They lack sufficient precision and sensitivity, especially for detecting minute defects, resulting in low accuracy in product quality control.

[0003] However, existing devices, such as the utility model patent application number 201420359010X, which discloses an appearance inspection device for electronic component taping and packaging equipment, are used for electronic component taping and packaging. This device includes an upper appearance inspection device and a lower appearance inspection device, respectively installed next to the turntables on the upper and lower surfaces of the work panel. The upper appearance inspection device consists of a Y-axis moving base, an X-axis moving base, a CCD camera, and a light source; the lower appearance inspection device consists of a Y-axis moving base, an X-axis moving base, a CCD camera, a right-angle sharp lens, and a light source. These devices often require multiple loading, inspection, and unloading processes, which is not only inefficient but also increases the complexity and error of manual operation.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0027] As shown in the figure, an electronic component packaging appearance defect detection device includes: a base 1, a plurality of detection mechanisms 2 disposed above the base 1, and a moving mechanism 3 disposed directly below the detection mechanism;

[0028] It should be noted that both the detection mechanism 2 and the moving mechanism 3 are located above the base 1, and two sets of detection mechanisms 2 and moving mechanisms 3 can be set on one base 1. The two sets of detection mechanisms 2 and moving mechanisms 3 are arranged opposite to each other, so as to realize the simultaneous detection work of multiple stations. When the moving mechanism 3 moves the packaged electronic components (hereinafter referred to as the objects to be tested), it uses the cooperation of the flipping part and the control part 33 on the base 1 to flip the objects to be tested. The objects are then detected by the ultrasonic detectors 21 on the top and sides, which achieves rapid detection and avoids the process of loading-detecting-unloading multiple times.

[0029] The base 1 includes: a base 1 body and several flipping parts disposed above the base 1 body; the monitoring mechanism and the moving mechanism 3 are both disposed above the base 1, and the flipping parts are disposed on both sides of the moving mechanism 3;

[0030] In this utility model, the flipping component includes several flipping shafts 11 and a stop 13 disposed on the flipping shafts 11; the flipping shafts 11 and the stop 13 are connected by a connector 12; the flipping shaft 11 has a concave cross-section, the bottom of the connector 12 is slidably connected to the concave part of the flipping shaft 11, and several threaded holes are evenly provided at the concave bottom of the flipping shaft 11; the flipping shaft 11 is disposed on both sides of the moving mechanism 3; the connector 12 is T-shaped, the vertical part of the T-shape of the connector 12 is slidably connected to the flipping shaft 11, the horizontal part of the T-shape of the connector 12 has a slot in the middle, and threaded holes are provided on both sides of the slot, and bolts are provided; the stop 13 has a 7-shaped cross-section, and the bottom of the vertical part of the stop 13 has a groove, which can be engaged with the slot and is interference fit.

[0031] It should be noted that the flip shaft 11 is concave and the connector 12 is T-shaped. The vertical part of the connector 12 slides in the concave groove of the flip shaft 11, and several threaded holes are evenly opened at the bottom of the groove of the flip shaft 11. A slot is opened at the middle position of the horizontal part of the connector 12, and threaded holes are opened on both sides of the slot. Three connectors 12 are provided on one flip shaft 11. The vertical part of the bottom of the connector 12 is slidably connected to the groove of the flip shaft 11. After sliding to a fixed position, the two are fixedly connected by threads through the threaded holes on both sides of the connector 12 and the threaded holes at the bottom of the groove of the flip shaft 11. A stop 13 is provided on each connector 12, and a slot is opened at the bottom of the stop 13. The slot and the slot are fixedly connected by snap-fit, and the two are interference fit. Two flip shafts 11 are provided in each flip part. The two flip shafts 11 are symmetrically arranged on both sides of the moving mechanism 3, and the connectors 12 on the flip shafts 11 are also symmetrically arranged.

[0032] The monitoring mechanism includes: several ultrasonic detectors 21, and a bracket 20 for supporting the ultrasonic detectors 21; the bracket 20 is fixedly connected to the base 1 body.

[0033] In this utility model, several ultrasonic detectors 21 are provided. The ultrasonic detectors 21 are used to emit and receive ultrasonic waves to detect the appearance of electronic component packaging. The ultrasonic detectors 21 are respectively arranged on both sides and directly above the moving mechanism 3.

[0034] It should be noted that the ultrasonic wave detector is used to emit and receive ultrasonic waves to detect whether there are scratches or other defects on the surface of electronic components. There are three ultrasonic detectors 21. One is a large ultrasonic detector 21, which has four ultrasonic emission and receiving points arranged in sequence inside. The large ultrasonic detector 21 is fixedly connected to the bracket 20 and is used to detect four sides that are parallel to the horizontal plane. It is set directly above the moving mechanism 3. The other two are small ultrasonic detectors 21, which are fixedly connected to the flip shaft 11 near the motor 30 and are used to detect sides that are parallel to the vertical plane.

[0035] The moving mechanism 3 includes: a motor 30, a sliding component fixedly connected to the motor 30, and a placement component disposed directly above the sliding component; the sliding component and the placement component are slidably connected, and the sliding component is used to drive the placement component to move.

[0036] In this utility model, the sliding component includes a slide rail 31 and a threaded rod disposed on the slide rail 31; the threaded rod is used to control the movement of the placement component; one end of the threaded rod is rotatably connected to the slide rail 31, and the other end of the threaded rod passes through the slide rail 31 and is fixedly connected to the motor 30.

[0037] In this utility model, the placement component includes a slider 32 and a control component 33 fixedly connected to the slider 32; the bottom of the slider 32 is slidably connected to the slide rail 31, and a threaded hole is opened in the middle of the bottom of the slider 32 and engages with the threaded rod; the cross-section of the control component 33 is arranged in the shape of a "7", and a control hole 34 is opened at the top of the control component 33. The control hole 34 is square, and flip grooves 35 are opened on both sides of the bottom of the vertical part of the control component 33.

[0038] It should be noted that the motor 30 is a servo motor, which is fixedly connected to the base 1 and is located on the same axis as the slide rail 31. The motor 30 is fixedly connected to one end of the threaded rod, and the other end of the threaded rod is rotatably connected to the slide rail 31. The slider 32 is slidably connected to the slide rail 31 and is threaded. Thus, by rotating the motor 30 in both directions, the slider 32 is controlled to move back and forth on the slide rail 31. The control component 33 is arranged in a figure-7 shape, and a square fixing hole is opened in the middle part of its horizontal plane. The part to be tested is placed above the slider 32 and located inside the control hole 34. Flip grooves 35 are opened on both sides of the bottom of the vertical part of the control component 33.

[0039] During operation, the motor 30 rotates, driving the slider 32 to move along the slide rail 31 to the end away from the motor 30 via the threaded rod. After the slider 32 moves to the end of the slide rail 31 away from the motor 30, the workpiece to be tested is placed on the slider 32 through the control hole 34. The ultrasonic detector 21 at the top detects the horizontal plane of the workpiece. The motor 30 rotates again, driving the slider 32 to move closer to the motor 30. When it passes the stop 13, the stop 13 blocks the bottom of the workpiece and is located at the front bottom in the direction of movement of the workpiece. As the motor 30 rotates, the stop 13 blocks the workpiece, preventing it from moving forward. As the motor 30 rotates, the control hole 34 moves to the rear in the direction of movement of the workpiece. The top of the device is pushed forward, and through the interaction of the stop 13 and the control unit 33, a misaligned and reverse thrust is applied to the part to be tested, causing the part to be tested to flip over. This causes the side parallel to the horizontal plane to change, and the ultrasonic detector 21 at the top tests another plane. As the motor 30 rotates, the stop 13 and the control unit 33 continuously cause the part to be tested to flip over, so that the ultrasonic detector 21 at the top tests four different sides parallel to the horizontal plane. When the slider 32 moves to the end of the slide rail 31 near the end of the motor 30, the other two ultrasonic detectors 21 test the side of the part to be tested parallel to the vertical plane, thus completing the defect detection of the six sides of the part to be tested.

The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
