Description

Technical Field

[0001] This utility model relates to the field of testing instrument technology, and in particular to an automatic testing device for an ultrasonic wind speed sensor. Background Technology

[0002] Ultrasonic anemometers primarily measure wind speed and direction using the ultrasonic time-of-flight method. They calculate wind speed and direction by measuring the time difference in sound wave propagation in different directions. Specifically, the sensor contains one or more pairs of ultrasonic transmitters and receivers, mounted at two opposite positions in a vertical direction. When there is no wind, the propagation time of the ultrasonic waves between the two sensors is symmetrical. However, when there is wind, wind speed and direction affect the propagation speed and direction of the ultrasonic waves, resulting in a time difference. By accurately measuring these time differences, wind speed and direction can be calculated.

[0003] Existing ultrasonic anemometers generally consist of a base, a cover, and several pins. The pins are inserted into the base, and the cover confines the pins between the base and the cover. A ribbon cable is connected to the base to complete the assembly of the ultrasonic sensor. After assembly, the sensor needs to be inspected. Current inspection methods mostly rely on visual inspection to check whether the cover is properly assembled, whether the ribbon cable is warped, etc. However, manual inspection is inefficient and inaccurate, making it unsuitable for widespread use. Utility Model Content

[0004] To address the inefficiency of existing manual inspection methods for finished products, this invention provides an automatic inspection device for ultrasonic wind speed sensors. Through a four-station turntable structure, it sequentially presses the cap and straightens the wiring, then uses a vision module for inspection, replacing manual labor and enabling more efficient inspection of whether the finished product assembly is qualified.

[0005] This invention provides an automatic inspection device for ultrasonic anemometers, including a frame and a turntable rotatably mounted above the frame. Four sets of carriers for placing products are arranged circumferentially on the turntable. Around the turntable, in a counter-clockwise direction, are sequentially arranged a loading station, a primary pressing station, a secondary pressing station, and a vision inspection station. The primary pressing station has a first pressing module, the secondary pressing station has a second pressing module, and the vision inspection station has a vision module. The four carriers are sequentially switched between the loading station, primary pressing station, secondary pressing station, and vision inspection station via the turntable. The multiple stations circumferentially arranged around the turntable achieve pressing of the main body of the product and straightening of the wiring, replacing manual inspection of the finished product's quality, effectively improving inspection accuracy and efficiency.

[0006] Furthermore, the product includes a main body and a cable. The carrier has corresponding product slots to accommodate the main body and cable slots to accommodate the cable. The product slots and cable slots are connected, and suction cups are also installed inside the product slots. The suction cups are used to adhere and fix the main body of the product, ensuring that the product is stably placed inside the carrier.

[0007] Furthermore, notches are symmetrically provided on both sides of the product slot along its length. One end of the wire slot is connected to the product slot, and the other end is provided with a second notch. Notch one facilitates the placement and removal of the main body, while notch two facilitates the placement and removal of the wiring.

[0008] Furthermore, the first pressing module includes a first support arm, a first pressing head, and a first adjusting component. The first adjusting component is fixedly mounted on the frame. One end of the first support arm is fixed to the first adjusting component, and the other end is connected to the first pressing head. The first pressing head includes a first contouring pressure head that is adapted to the main body. The first adjusting component drives the first pressing head to move vertically to apply pressure to the main body of the product.

[0009] Furthermore, the second pressing module includes a second support arm, a second pressing head, and a second adjusting component. The second adjusting component is fixedly mounted on the frame. One end of the second support arm is fixed to the second adjusting component, and the other end is connected to the second pressing head. The second pressing head includes a second contouring pressure head adapted to the product cable. The second pressing head is moved vertically by the second adjusting component to apply pressure to the product cable.

[0010] Furthermore, the first and second pressing heads also include a mounting base and an adjusting cylinder. The mounting base is fixedly connected to the support arm, and the fixed end of the adjusting cylinder is connected to the mounting base. The first and second contouring pressing heads move vertically via the movable end of the adjusting cylinder. The longitudinal movement of the pressing heads via the adjusting cylinder ensures good stability.

[0011] Furthermore, both the first and second adjusting components include a first slide and a second slide that are perpendicular to each other. The first slide is fixedly mounted on the frame, and the second slide is movably mounted on the first slide via a slide block. The support arm is movably mounted on the second slide via a slide block. Through the cooperation of the first and second slides, the cross adjustment of the support arm is achieved.

[0012] Furthermore, the vision module includes a camera, a camera mount, a light source, and a third support arm. One end of the third support arm is fixedly mounted on the frame, and the other end is equipped with the camera mount. The camera moves vertically along the camera mount via an adjusting cylinder. The light source is fixedly mounted at the bottom of the camera mount and located below the camera. Through the cooperation of the camera and the light source, the pressurized product is imaged and inspected.

[0013] Furthermore, the frame is equipped with a first track and a second track for driving the third support arm. The first track and the second track are arranged perpendicularly to each other. The first track is fixedly mounted on the frame, and the second track is movably mounted on the first track via a slider. The third support arm is movably mounted on the second track via a slider. The cooperation of the first track and the second track expands the camera's adjustment range.

[0014] Furthermore, a dustproof enclosure is installed on the frame, covering the turntable, with an opening on one side. The dustproof enclosure protects each module.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model provides an automatic detection device for ultrasonic wind speed sensors. The device loads and unloads products through a loading station set at the edge of the frame, and then uses multiple stations arranged circumferentially around the turntable to press-fit the main body of the product and straighten the product wiring. It also replaces manual inspection of finished products using a vision module, thereby effectively improving detection accuracy and efficiency. Attached Figure Description

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0024] To achieve automated product detection, an automated detection device for ultrasonic anemometers is designed, such as... Figure 1 As shown, the device includes a frame 1 and a turntable 2 rotatably mounted above the frame 1. The turntable 2 has four sets of carriers 3 arranged circumferentially for placing products. Around the turntable 2, along its counterclockwise rotation direction, there are a loading station 24, a primary pressing station 21, a secondary pressing station 22, and a vision inspection station 23 arranged sequentially. The primary pressing station 21 is equipped with a first pressing module 4, the secondary pressing station 22 is equipped with a second pressing module 5, and the vision inspection station 23 is equipped with a vision module 6. The four sets of carriers 3 can be switched sequentially between the loading station 24, the primary pressing station 21, the secondary pressing station 22, and the vision inspection station 23 via the turntable 2.

[0025] In use, the pre-assembled product is placed on carrier 3, and the motor drives the turntable 2 to rotate. The product body is pressurized by the first pressing module 4, and the product wiring is pressurized and straightened by the second pressing module 5. Finally, the product is inspected for compliance by visual inspection station 23. At the same time, the qualified product can be unloaded at the loading station 24 and replaced with the product to be inspected. The inspection is carried out continuously without stopping the machine, replacing manual labor and effectively improving the inspection efficiency and accuracy of the product.

[0026] To ensure stable placement of the product, which includes a main body and a cable, the carrier 3 has a product slot 31 for accommodating the main body and a cable slot 32 for accommodating the cable. The product slot 31 and the cable slot 32 are connected, and a suction cup 33 is also provided inside the product slot 31. The suction cup 33 fixes the main body of the product in the product slot 31, thus achieving stable placement of the product.

[0027] To facilitate product placement and removal, the product slot 31 has symmetrical notches 34 on both sides along its length. One end of the wire slot 32 is connected to the product slot 31, and the other end has a notch 35. The main body of the product can be removed from the product slot 31 through the notch 34, or the product wiring can be removed from the wire slot 32 through the notch 35.

[0028] like Figure 2 As shown, specifically, the first pressing module 4 includes a first support arm 41, a first pressing head, and a first adjusting component. The first adjusting component is fixedly mounted on the frame 1. One end of the first support arm 41 is fixed to the first adjusting component, and the other end is connected to the first pressing head. The first pressing head includes a first contouring pressing head 42 adapted to the main body. It also includes a proximity sensor. When the carrier 3 approaches, it triggers the first adjusting component to move the first pressing head downwards to pressurize the product body.

[0029] The second pressing module 5 includes a second support arm 51, a second pressing head, and a second adjusting component. The second adjusting component is fixedly mounted on the frame 1. One end of the second support arm 51 is fixed to the second adjusting component, and the other end is connected to the second pressing head. The second pressing head includes a second contour pressing head 52 adapted to the product cable. It also includes a proximity sensor. When the carrier 3 approaches, it triggers the second adjusting component to move the second pressing head downwards to pressurize the product cable.

[0030] The first and second pressing heads also include a mounting base 43 and an adjusting cylinder 44. The mounting base 43 is fixedly connected to the support arm, and the fixed end of the adjusting cylinder 44 is connected to the mounting base 43. The first contouring pressing head 42 and the second contouring pressing head 52 move vertically through the movable end of the adjusting cylinder 44. The extension and retraction of the adjusting cylinder 44 drives the longitudinal displacement of the pressing heads.

[0031] To expand the adjustment range, both the first and second adjusting components include a first slide 45 and a second slide 46 that are perpendicular to each other. The first slide 45 is fixedly mounted on the frame 1, and the second slide 46 is movably mounted on the first slide 45 via a slide block. The support arm is movably mounted on the second slide 46 via a slide block. Through the cooperation of the first slide 45 and the second slide 46, the two sets of pressing heads can be adjusted in the X-axis and Y-axis directions.

[0032] like Figure 3As shown, specifically, the vision module 6 includes a camera 62, a camera mount 64, a light source 63, and a third support arm 61. One end of the third support arm 61 is fixedly mounted on the frame 1, and the other end is mounted on the camera mount 64. The camera 62 moves vertically along the camera mount 64 via an adjusting cylinder 44. The light source 63 is fixedly mounted at the bottom of the camera mount 64 and located below the camera 62. The vision module 6 uses the industrial camera 62 to automatically detect product defects and measure dimensions, replacing inefficient manual inspection. The camera 62 captures product image information and transmits it to a remote terminal for data comparison. When a defective product is detected, an alert is issued. When the defective product rotates to the loading station 24, it can be promptly removed and placed in the defective product collection box. The adjusting cylinder 44 extends and retracts, causing the camera 62 to adjust along the Z-axis to adjust the distance between it and the product. It also adjusts the focal length of the vision module 6, and by lengthening the focal length, the field of view of the camera 62 can be narrowed to improve the accuracy of product imaging.

[0033] To expand the adjustment range, the frame 1 is equipped with a first track 65 and a second track 66 for driving the third support arm 61. The first track 65 and the second track 66 are arranged perpendicularly to each other. The first track 65 is fixedly mounted on the frame 1, and the second track 66 is movably mounted on the first track 65 via a slider. The third support arm 61 is movably mounted on the second track 66 via a slider. Through the cooperation of the first track 65 and the second track 66, the vision module 6 can be adjusted in the X-axis and Y-axis directions.

[0034] like Figure 4 As shown, in order to protect each module, a dustproof housing 11 is provided on the frame 1. The dustproof housing 11 covers the outer perimeter of the turntable 2, and one side of the dustproof housing 11 has an opening. The dustproof housing 11 constitutes a relatively closed working environment, which can effectively protect each module and product.

[0035] The above description is illustrative only and not restrictive of this utility model. Those skilled in the art will understand that many modifications, variations or equivalents can be made without departing from the spirit and scope defined by the appended claims, and all such modifications, variations or equivalents will fall within the protection scope of this utility model.
