Description

Technical Field

[0001] This invention relates to the field of sensor detection technology, and in particular to a fully automated detection device for miniature intelligent sensors. Background Technology

[0002] Intelligent sensors are sensors with information processing capabilities. Equipped with a microprocessor, they possess the ability to acquire, process, and exchange information, representing a product of sensor integration combined with microprocessors. Compared to conventional sensors, intelligent sensors offer three main advantages: high-precision information acquisition through software technology at a low cost; a degree of programmable automation; and diverse functionality. A good intelligent sensor is a microprocessor-driven sensor and instrument suite with communication and onboard diagnostic functions. Intelligent sensors can store various detected physical quantities and process this data according to instructions, thereby creating new data. Intelligent sensors can exchange information with each other, autonomously decide which data to transmit, discard abnormal data, and perform analysis and statistical calculations.

[0003] To understand how miniature smart sensors perform in different environments, it is often necessary to test the sensors on one environmental simulation testing device and then switch to another, sometimes requiring multiple switches, which is detrimental to improving testing efficiency. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a fully automated detection device for miniature intelligent sensors, which has the advantage of automatically switching the miniature intelligent sensor to be tested between different detection chambers. This solves the problem in existing technologies that require switching from one environmental simulation detection device to another after the miniature intelligent sensor has been tested on one environmental simulation detection device, or even requiring multiple switching, which is not conducive to improving detection efficiency.

[0005] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0006] A fully automated testing device for miniature intelligent sensors includes a testing mechanism and a feeding mechanism. The testing mechanism includes a support plate with a plurality of test chambers arranged equidistantly in a ring on the support plate. Each of the test chambers on the support plate has an opening structure, and the opening structure of each test chamber points towards the center of the support plate. The feeding mechanism includes a turntable positioned above the support plate and located between the test chambers. A feeding rod that can extend and retract radially relative to the turntable is mounted on the turntable. A clamping platform is fixedly connected to the outer end of the feeding rod. The position of the feeding rod corresponds to the position of the test chambers, so that the feeding rod can drive the clamping platform to push the miniature intelligent sensor to be tested into the test chamber through the opening structure.

[0007] Furthermore, different testing environment factors are simulated in different testing chambers. These different testing environment factors include different temperature and humidity environments, different electromagnetic environments, or combinations of various testing environment factors.

[0008] Furthermore, the turntable is equipped with several feed rods that can extend and retract radially relative to the turntable, and the feed rods are arranged in a ring at equal intervals relative to the turntable, with the included angle between the feed rods corresponding to the included angle between the test chambers.

[0009] Furthermore, the clamping stage includes a platform, on which two first elastic members are fixedly connected. Clamping plates are connected to the platform through the two first elastic members, that is, the two first elastic members are respectively connected to clamping plates. The two clamping plates are arranged opposite to each other, and buffer layers are fixedly connected to the inner surfaces of the two clamping plates that are pointing opposite to each other. An electrical interface is embedded in the platform, which is used to connect to a micro intelligent sensor.

[0010] Furthermore, a stepper motor or servo motor is provided on the lower side of the support plate. The stepper motor or servo motor is fixedly connected to a rotating shaft. The rotating shaft rotates through the support plate and extends to the upper side of the support plate. The rotating shaft and the turntable are fixedly connected.

[0011] Furthermore, by using a stepper motor or servo motor to drive the rotating shaft to rotate a predetermined angle each time, the rotating shaft can drive the turntable to rotate a predetermined angle after rotation.

[0012] Furthermore, the turntable includes a disc body with a central hole in the middle, a second elastic element in the central hole, one end of the second elastic element being connected to the disc body, and the other end of the second elastic element being connected to a connecting plate. The rotating shaft and the connecting plate are fixedly connected. A clamping structure is fixedly connected to the bearing plate, and the clamping structure can further improve the fastening between the disc body and the bearing plate.

[0013] Furthermore, a limiting ring is rotatably connected to the disc body, and the feeding rod is slidably connected to the limiting ring. A rotating rod is rotatably connected to the end of the feeding rod away from the clamping table, and the other end of the rotating rod is rotatably connected to the connecting plate.

[0014] Furthermore, the rotary feeding method, which combines the turntable and the feed rod, is as follows:

[0015] The clamping element clamps the disc body;

[0016] The rotating shaft rotates, causing the connecting plate to rotate. The connecting plate drives the feeding rod to move through the rotating rod, pulling the clamping table out of the test box. At the same time, the second elastic element is stretched.

[0017] The clamping element releases the disc body, and driven by the elastic potential energy of the second elastic element, the disc body rotates. At the same time, the feeding rod moves to the outside of the disc body, sending the clamping table into the next test box. This allows for more efficient and portable feeding of the turntable and the rotating feeding rod.

[0018] Furthermore, the feeding rod is connected to the disc body via a third elastic element, which can assist in the resetting of the feeding rod.

[0019] Furthermore, the clamping component includes an electric push rod, which is fixedly connected to the bearing plate. The extended end of the electric push rod is fixedly connected to a universal ball. The lower surface of the disc is provided with equidistant grooves in an annular shape, and the rolling end of the universal ball can be engaged in the grooves.

[0020] Furthermore, when the rotating shaft drives the connecting plate to move, the rolling end of the universal ball engages in the slot, preventing the disc from rotating. However, the second elastic element continuously applies elastic potential energy to the disc, and this potential energy continuously increases. When it reaches a predetermined value, the slot and the universal ball disengage, allowing the disc to rotate. This then causes the next slot to engage with the universal ball, fixing the disc in place again. This achieves automatic clamping and releasing of the disc. The universal ball supports the disc, preventing it from tilting and ensuring greater stability. The height of the disc can be adjusted by raising and lowering the electric push rod.

[0021] Furthermore, the opening structure is provided with a test door, which includes a first door body and a second door body. The first door body is connected to the test chamber via a fourth elastic member, and the second door body is connected to the test chamber via a fifth elastic member.

[0022] Furthermore, the adjacent edges of the first door and the second door are fitted together, and the adjacent edges of the first door and the second door are respectively provided with a first card interface and a second card interface that fit together; the first card interface and the second card interface can fit with the outer peripheral surface of the feeding rod.

[0023] Furthermore, by applying pressure to the clamping platform via the feeding rod, the first and second doors can be forced apart. When the clamping platform enters the testing chamber, the first and second doors can still be closed, ensuring testing accuracy. The feeding rod can be supported via the first and second locking interfaces, making the clamping platform more stable during testing.

[0024] Furthermore, rollers are installed at the four corners of the clamping platform to push the first and second doors apart, preventing the first and second doors from damaging the miniature intelligent sensor to be detected.

[0025] The beneficial effects of this invention are as follows: By using the testing mechanism and the feeding mechanism, the invention enables the automatic switching of the micro-intelligent sensor to be tested between different testing chambers. This solves the problem in the prior art that the micro-intelligent sensor needs to be tested on one environmental simulation testing device and then switched to another environmental simulation testing device for further testing, or even requires multiple switching, which is not conducive to improving testing efficiency.

[0026] The miniature smart sensor to be tested is loaded onto the clamping table. By rotating the turntable, the feeding rod is aligned with the opening structure of the test chamber. Then, the feeding rod is extended to allow the miniature smart sensor to enter the test chamber through the opening structure. After testing in one test chamber is completed, the feeding rod is retracted to pull the miniature smart sensor out of the current test chamber. Then, the turntable rotates, and the feeding rod is extended again to allow the miniature smart sensor to enter the next test chamber for continued testing. This allows the miniature smart sensor to be tested to switch between different test chambers and be tested sequentially.

[0027] Different test environments are simulated in different test chambers, such as different temperature and humidity environments, different electromagnetic environments, and various combinations of environments.

[0028] The turntable is equipped with several feed rods that can extend and retract radially relative to the turntable. The feed rods are arranged in a ring at equal intervals relative to the turntable, and the included angle between the feed rods corresponds to the included angle between the test chambers. This allows multiple miniature intelligent sensors to detect simultaneously, improving detection efficiency.

[0029] The micro-intelligent sensor can be held by the interaction of two clamps. The micro-intelligent sensor is connected to the electrical interface to realize signal data acquisition and can detect various parameters when the micro-intelligent sensor is in normal use.

[0038] The embodiments of this disclosure will now be described in detail with reference to the accompanying drawings.

[0039] The following specific examples illustrate the implementation of this disclosure. Those skilled in the art can easily understand other advantages and effects of this disclosure from the content disclosed in this specification. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. This disclosure can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this disclosure. It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0040] Example 1:

[0041] Please see Figure 1 , Figure 2 and Figure 3 A fully automatic detection device for a miniature intelligent sensor includes a testing mechanism and a feeding mechanism. The testing mechanism includes a support plate with several testing chambers arranged on it. The test chambers on the support plate can be arranged in a ring at equal intervals. Each test chamber on the support plate has an opening structure, and the opening structure of each test chamber points to the center of the support plate.

[0042] The feeding mechanism includes a turntable positioned above a support plate, between several test chambers. A feeding rod, capable of radial extension and retraction relative to the turntable, is mounted on the turntable. A clamping platform is fixedly connected to the outer end of the feeding rod. The position of the feeding rod corresponds to the position of the test chambers, enabling the feeding rod to drive the clamping platform to guide the miniature intelligent sensor to be tested through an opening structure into the test chamber. It should be noted that the number of feeding rods is not specifically defined in this application and can be set according to actual practical needs.

[0043] The process involves loading the miniature smart sensor to be tested onto the clamping table. The rotation of the turntable aligns the feed rod with the opening of the testing chamber. The feed rod then extends, allowing the sensor to pass through the opening and enter the testing chamber. Different testing chambers simulate different testing environments, such as varying temperatures and humidity levels, electromagnetic fields, and combinations thereof. After testing in one chamber, the feed rod retracts, removing the sensor. The turntable then rotates, and the feed rod extends again, allowing the sensor to proceed to the next chamber for testing. This process continues until all testing is complete. This method facilitates switching between different testing chambers for sequential testing of the same miniature smart sensor.

[0044] Please see Figure 1 The turntable is equipped with several feed rods that can extend and retract radially relative to the turntable. These feed rods are arranged in a circular, equidistant pattern relative to the turntable, and the angle between the feed rods corresponds to the angle between the test chambers. This configuration allows for simultaneous detection by multiple miniature intelligent sensors, improving detection efficiency.

[0045] Please see Figure 3 The clamping stage includes a platform, on which two first elastic elements are fixedly connected. Each of the two first elastic elements (e.g., spring sheets) is connected to a clamping plate, i.e., each of the two first elastic elements is connected to a clamping plate. The two clamping plates are arranged opposite to each other, and a buffer layer is fixedly connected to the inner surface of each of the two clamping plates that are pointing opposite to each other. An electrical interface is embedded in the platform, which is used to connect to a micro smart sensor.

[0046] The micro-intelligent sensor can be held by the interaction of two clamps. The micro-intelligent sensor is connected to the electrical interface to realize signal data acquisition and can detect various parameters when the micro-intelligent sensor is in normal use.

[0047] Please see Figure 4 A stepper motor or servo motor is provided on the lower side of the support plate. The stepper motor or servo motor is fixedly connected to a rotating shaft. The rotating shaft rotates through the support plate and extends to the upper side of the support plate. The rotating shaft and the turntable are fixedly connected.

[0048] Each time a stepper motor or servo motor drives the rotating shaft to rotate by a predetermined angle, the rotating shaft can drive the turntable to rotate by a predetermined angle.

[0049] Please see Figure 4 The turntable includes a disc body with a central hole in the middle and a second elastic element (e.g., a spring) in the central hole. One end of the second elastic element is connected to the disc body, and the other end of the second elastic element is connected to a connecting plate. The rotating shaft and the connecting plate are fixedly connected. A clamping structure is fixedly connected to the bearing plate, which can further improve the fastening between the disc body and the bearing plate.

[0050] A limit ring is rotatably connected to the disc body, and the feeding rod is slidably connected to the limit ring. A rotating rod is rotatably connected to the end of the feeding rod away from the clamping table, and the other end of the rotating rod is rotatably connected to the connecting plate.

[0051] The rotary feeding method, which combines a turntable and a feed bar, is as follows:

[0052] Step 1: Clamp the disc body with the clamping components;

[0053] Step 2: The rotating shaft rotates, causing the connecting plate to rotate. The connecting plate drives the feeding rod to move through the rotating rod, pulling the clamping table out of the test box. At the same time, the second elastic element is stretched.

[0054] Step 3: The clamping component releases the disc body. Driven by the elastic potential energy of the second elastic component, the disc body rotates. At the same time, the feeding rod moves to the outside of the disc body, sending the clamping platform into the next test box. This allows for more efficient and portable feeding of the turntable and the rotating feeding rod.

[0055] Please see Figure 1 and Figure 6 The feed rod is connected to the disc body via a third elastic element, which can assist in the reset of the feed rod.

[0056] Please see Figure 4 and Figure 5 The clamping component includes an electric push rod, which is fixedly connected to the bearing plate. The extended end of the electric push rod is fixedly connected to a universal ball. The lower surface of the disc is provided with equidistant grooves in an annular shape, and the rolling end of the universal ball can be engaged in the grooves.

[0057] When the rotating shaft drives the connecting plate to move, the rolling end of the universal ball engages in the slot, preventing the disc from rotating. However, the second elastic element continuously applies elastic potential energy to the disc, and this potential energy continuously increases. When it reaches a predetermined value, the slot and the universal ball disengage, allowing the disc to rotate. This then causes the next slot to engage with the universal ball, fixing the disc in place again. This achieves automatic clamping and releasing of the disc. The universal ball supports the disc, preventing it from tilting and ensuring greater stability. The height of the disc can be adjusted by raising and lowering the electric push rod.

[0058] Please see Figure 1 and Figure 6 The opening structure is provided with a test door, which includes a first door body and a second door body. The first door body is connected to the test chamber by a fourth elastic element (e.g., a spring sheet), and the second door body is connected to the test chamber by a fifth elastic element (e.g., a spring sheet).

[0059] The adjacent edges of the first door and the second door are fitted together, and the adjacent edges of the first door and the second door are respectively provided with a first card interface and a second card interface that fit together; the first card interface and the second card interface can fit with the outer peripheral surface of the feeding rod.

[0060] By applying pressure to the clamping platform using the feeding rod, the first and second doors can be forced open. When the clamping platform enters the testing chamber, the first and second doors can still be closed, ensuring testing accuracy. The feeding rod is supported by the first and second locking interfaces, making the clamping platform more stable during testing.

[0061] Please see Figure 3 Rollers are installed at the four corners of the clamping platform. These rollers are used to push the first and second doors apart, preventing the first and second doors from damaging the miniature intelligent sensor to be detected.

[0062] In operation, the miniature smart sensor to be tested is loaded onto the clamping table. The rotation of the turntable aligns the feed rod with the opening of the test chamber. The feed rod then extends, allowing the miniature smart sensor to enter the test chamber through the opening. Different test chambers simulate different testing environments, such as varying temperature and humidity levels, electromagnetic fields, and combinations thereof. After testing in one test chamber is completed, the feed rod retracts, removing the miniature smart sensor from the current chamber. The turntable then rotates, and the feed rod extends again, allowing the miniature smart sensor to enter the next test chamber for further testing. This process continues until all testing is completed. This method facilitates switching between different test chambers for sequential testing of the miniature smart sensor.
