Description

Technical Field

[0001] This invention relates to the technical field of sensor detection, and in particular to a fluxgate sensor appearance detection device. Background Technology

[0002] A fluxgate sensor is a transformer-type device modified based on the phenomenon of electromagnetic induction. It measures weak magnetic fields by utilizing the nonlinear relationship between the magnetic induction intensity and the magnetic field strength of a high-permeability magnetic core under saturation excitation of an alternating magnetic field. This physical phenomenon acts like a "gate" for the magnetic field of the measured environment. By passing through this "gate," the corresponding magnetic flux is modulated, and an induced electromotive force is generated. Fluxgate sensors are common weak magnetic field detection sensors and are widely used in fields such as medical treatment, geophysical exploration, space physics, and underwater magnetic anomaly detection. They have the advantages of low noise, small size, and wide bandwidth.

[0003] To ensure the proper functioning of fluxgate sensors, it is typically necessary to perform corresponding quality inspections. The most basic of these inspections is to check the sensor's appearance. The sensor's appearance is used to determine whether it is functioning correctly. However, traditional inspection equipment often involves clamping the sensor, requiring manual inspection using the naked eye or measuring tools. While this method achieves the desired inspection effect, it is inefficient and prone to errors due to the relatively large margin of error. It also fails to accurately assess changes in the sensor's dimensions, resulting in poor inspection results that do not meet the requirements for appearance inspection. Summary of the Invention

[0004] In view of the problems of low detection efficiency and relatively large error in manual detection in the existing technology, which makes it impossible to accurately judge the changes in the appearance and size of the sensor, the present invention is proposed.

By cooperating with the screening component, the steering component, and the conveying component, the various surfaces of the sensor are inspected, thereby greatly improving the efficiency and accuracy of sensor appearance inspection.

[0012] In a preferred embodiment of the fluxgate sensor appearance inspection device of the present invention, the steering component includes a rotation drive member disposed on the conveying block and a fixing member rotatably disposed on the conveying block.

[0013] As a preferred embodiment of the magnetic fluxgate sensor appearance inspection device of the present invention, the rotating drive component includes: a fixed plate disposed on the conveying block; a second gear rotatably disposed on one side of the fixed plate; a first bevel gear rotatably disposed on the other side of the fixed plate; the second gear and the first bevel gear being fixedly connected; a push bracket disposed on the conveying block; a third gear disposed at the lower end of the push bracket; a second bevel gear disposed on the third gear and meshing with the first bevel gear; a fourth gear disposed at the upper end of the push bracket; a toothed belt disposed on the third gear and the fourth gear; and a rack disposed on the conveying bracket and meshing with the second gear, the rack being located between the front screening section and the rear screening section.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0032] Example 1

[0033] Reference Figures 1-4 ,as well as Figures 8-10 This first embodiment of the invention provides a fluxgate sensor appearance inspection device. The device includes a base 100, a support frame 200 mounted on the base 100, a conveying bracket 300 mounted on the support frame 200, a screening component 400 mounted on the conveying bracket 300 for screening and inspecting the sensor on the conveying component 600, a steering component 500 mounted on the conveying bracket 300 for rotating the sensor on the conveying component 600, and a conveying component 600 mounted on the conveying bracket 300 for moving the sensor on the conveying bracket 300. Through the cooperation of the screening component 400, the steering component 500, and the conveying component 600, various surfaces of the sensor are inspected, significantly improving the efficiency and accuracy of sensor appearance inspection.

[0034] The conveying assembly 600 includes a conveying block 601 formed in the conveying bracket 300 for placing sensors, a motor 602 set inside the conveying block 601 for driving the first gear 603 to rotate, the two ends of the motor 602 passing through the conveying block 601 to the outside, the first gear 603 set at both ends of the motor 602, and a tooth cavity 604 formed on the inner wall of the conveying bracket 300 for meshing with the first gear 603, which serves as the movement path when the first gear 603 rotates, so that the conveying block 601 moves according to the trajectory of the tooth cavity 604.

[0035] Furthermore, it also includes a screening box 700 disposed above the support frame 200 for storing unqualified sensors, and a collection box 800 disposed on the base 100 for storing qualified sensors.

[0036] During use, the sensor is placed above the conveyor block 601. At this time, the motor 602 rotates, which drives the first gear 603 on both sides of the conveyor block 601 to rotate. Since the first gear 603 meshes with the teeth in the tooth cavity 604, when the first gear 603 rotates, the motor 602 will push the conveyor block 601 to move along the trajectory of the tooth cavity 604. When the sensor is moved to the screening component 400, the screening component 400 will detect and screen the sensor on the conveyor block 601. When the sensor completes the detection of a set of sides, the steering component 500 will control the sensor to rotate. Then, driven by the conveyor block 601, it will enter the screening component 400 to detect and screen the undetected sides. Finally, the unqualified sensors will slide into the screening box 700, and the qualified sensors will fall naturally into the collection box 800 after the conveyor block 601 moves to the end.

[0037] Example 2

[0038] Reference Figures 1-4 , Figure 7 , Figure 8 ,as well as Figure 10 This is the second embodiment of the present invention, which differs from the first embodiment in that it realizes automatic detection and sieving of the sensor.

[0039] Compared to Embodiment 1, the screening assembly 400 further includes a front screening section 401 disposed on the conveying support 300 and a rear screening section 402 disposed on the conveying support 300. The front screening section 401 and the rear screening section 402 have the same size and are used to screen different sides of the test item respectively.

[0040] The front screening section 401 includes an actuating element 401a disposed on the conveying bracket 300 for detecting the size of the item and driving the switch assembly to slide according to the different changes in the size of the item, and a switch element 401b disposed on the actuating element 401a for controlling the sliding of the item by driving the actuating assembly.

[0041] The starting component 401a includes a support body 401a-1 mounted on the conveying bracket 300 for support, a cavity inside the support body 401a-1, a push plate 401a-2 mounted in the cavity for movement within the cavity, a transmission rod 401a-3 mounted on the push plate 401a-2 for mounting a rotating wheel 401a-4, a rotating wheel 401a-4 mounted on the transmission rod 401a-3 near the conveying block 601 for the sensor surface, the rotating wheel 401a-4 having two layers with a certain gap between the two sides, and a first spring 401a-5 mounted between the push plate 401a-2 and the cavity for resetting after the transmission rod 401a-3 drives the rotating wheel 401a-4 to move.

[0042] The switching component 401b includes a starting plate 401b-1 located at the end of the transmission rod 401a-3 away from the rotating wheel 401a-4, for sliding with the sliding groove 401b-2; sliding grooves 401b-2 located on both sides of the conveying block 601 for cooperating with the starting plate 401b-1; a slot on the conveying bracket 300 through which the starting plate 401b-1 extends to the inside of the conveying bracket 300; a pressure plate 401b-3 located in the conveying block 601 for tilting the conveying block 601; the pressure plate 401b-3 being fixedly connected to the motor 602; a tension spring 401b-4 located between the pressure plate 401b-3 and the inner wall of the conveying block 601 for returning the pressure plate 401b-3 to its original position; and a reset block 401b-5 located on the conveying bracket 300 for bringing the conveying block 601 to a horizontal position.

[0043] During use, when the conveyor block 601 drives the sensor placed above it to slide along the trajectory of the toothed cavity 604, the unloaded state of the conveyor block 601 is tilted. When the conveyor block 601 moves to the position of the reset block 401b-5, the reset block 401b-5 will raise the conveyor block 601 to a horizontal state. At this time, the tension spring 401b-4 is under force, causing the conveyor block 601 to tend to return to the tilted state. As the conveyor block 601 moves, the starter plate 401b-1 will slowly engage with the sliding groove 401b-2 on the conveyor block 601. The surface of the sensor and the rotating wheel 401b-4 are then aligned. When the 1a-4 busbar is in contact, if the sensor size and appearance are qualified, the sensor can move smoothly with the rotating wheel 401a-4. If it is not qualified, the size change or local protrusion on the sensor will push the rotating wheel 401a-4 to compress the first spring 401a-5 and push the transmission rod 401a-3 to drive the starting plate 401b-1 to slide, thereby controlling the sensor to slide down. Then the conveyor block 601 will be forced back to the tilted state. After the conveyor block 601 leaves, the first spring 401a-5 will push the rotating wheel 401a-4 to reset, realizing the automatic detection and screening of the sensor.

[0044] The remaining structure is the same as that in Example 1.

[0045] Example 3

[0046] Reference Figures 1-10 This is the third embodiment of the present invention, which differs from the second embodiment in that it achieves comprehensive detection of the sensor.

[0047] Compared to Embodiment 2, the steering assembly 500 further includes a rotation drive 501 disposed on the conveying block 601, a drive fixing member 502 for driving the sensor to rotate, and a fixing member 502 rotatably disposed on the conveying block 601, the fixing member 502 being rotatably connected to the conveying block 601 for locking and fixing the sensor.

[0048] The rotating drive component 501 includes a fixed plate 501a disposed on the conveying block 601 for fixed support, a second gear 501b rotatably disposed on one side of the fixed plate 501a, a first bevel gear 501c rotatably disposed on the other side of the fixed plate 501a, the second gear 501b and the first bevel gear 501c being fixedly connected, a push bracket 501d disposed on the conveying block 601, a third gear 501e disposed at the lower end of the push bracket 501d, a second bevel gear 501f disposed on the third gear 501e and meshing with the first bevel gear 501c, a fourth gear 501g disposed at the upper end of the push bracket 501d, a toothed belt 501h disposed on the third gear 501e and the fourth gear 501g, and a rack 501i disposed on the conveying bracket 300 and meshing with the second gear 501b, the rack 501i being located between the front screening section 401 and the rear screening section 402.

[0049] The fixing component 502 includes a support plate 502a rotatably disposed on the side of the push bracket 501d away from the fourth gear 501g, the support plate 502a and the fourth gear 501g being fixedly connected, used to drive the sliding rod 502b to rotate; the sliding rod 502b slidably disposed between the support plate 502a and the push bracket 501d, used to cooperate with the second spring 502d to drive the front clamping plate 502c to move left and right; the front clamping plate 502c disposed at the end of the sliding rod 502b away from the push bracket 501d, used to cooperate with the rear clamping plate 502f to clamp the sensor; the second spring 502d disposed between the support plate 502a and the front clamping plate 502c; a rotating push rod 502e disposed at the end of the conveyor block 601 away from the first gear 603, used to rotate when pushed by the conveyor block 601; and a rear clamping plate 502f disposed above the rotating push rod 502e.

[0050] During use, before the conveyor block 601 is locked by the starter plate 401b-1, the starter plate 401b-1 will push the rotating rod 502e to rotate as the conveyor block 601 slides, thereby pushing the rotating rod 502e up and locking it. At this time, both ends of the sensor can be inserted into the front clamping plate 502c and the rear clamping plate 502f. When the sensor is inserted, the second spring 502d will be compressed, thereby clamping the sensor. When the conveyor block 601 moves to the turning position, the second gear 501b will mesh with the rack 501i. As the conveyor block 601 moves, the second gear 501b will rotate, thereby driving the first bevel gear 501c to rotate, which in turn drives the second bevel gear 501f to drive the third gear 501e to rotate, and by driving the fourth gear 501g to drive the front clamping plate 502c to rotate, thereby realizing the rotation of the sensor and thus detecting other surfaces of the sensor. With this setting, the sensor rotation can be automatically completed while the conveyor block 601 is conveying.
