Description

Technical Field

[0001] The present invention belongs to the technical field of test equipment, and in particular relates to an inertial measurement unit test device. Background Art

[0002] An inertial measurement unit is a device used to measure the three-axis attitude angle (or angular rate) and acceleration of an object. It usually combines an accelerometer and a gyroscope, and sometimes also includes a magnetometer, to comprehensively measure and report the specific force, angular velocity, and surrounding magnetic field of the object. With the development of technology and the pursuit of the functions of mobile devices in society, today's small consumer electronic products (such as mobile phones, tablet computers, and VR devices, etc.) are generally equipped with inertial measurement units.

[0003] In electronic product manufacturing enterprises, in order to ensure the performance, quality, and reliability of electronic products when they leave the factory, the manufacturing enterprises generally test the electronic products, and the inertial measurement units in the electronic products are no exception. In a conventional inertial measurement unit test device, generally, an electronic product is loaded from a conveyor line to a test station by a loading mechanism, and the test station then pushes the product to move linearly, so as to test the inertial measurement unit of the electronic product. Finally, the tested electronic product is unloaded to the conveyor line by an unloading mechanism; therefore, the following technical problems exist: 1. Since the electronic product needs to be loaded and unloaded from the test station before and after the test, the test steps are cumbersome and the test efficiency is low; 2. Since a loading and unloading mechanism needs to be set up, the production cost of the production line is high and the occupied space is large; 3. Since the conventional test equipment generally only simply pushes the product to move linearly, it is difficult to fully reflect the performance of the inertial measurement unit during the test. Summary of the Invention

[0004] The purpose of the present invention is to provide an inertial measurement unit test device to solve the technical defects described in the background art.

[0005] The inertial measurement unit testing device comprises an x-axis testing platform, on which an x-axis motor is mounted, the x-axis motor is drivingly connected to an x-axis rotating shaft arranged longitudinally, an x-axis rotating frame arranged downwardly tilted is fixed on the x-axis rotating shaft, the x-axis rotating frame is provided with a plurality of x-testing channels arranged downwardly tilted, an entrance at the top of the x-testing channel is connected to a production line so that the production line can send products placed thereon into the x-testing channel, an x-interception motor is mounted on the x-axis rotating frame, the x-interception motor is drivingly connected to an x-interception rotating shaft, an x-interception block extending outward is fixed on the x-interception rotating shaft, the x-interception motor is used to drive the x-interception rotating shaft to drive the x-interception block to swing into the lower end of the x-testing channel so as to limit the product from sliding out of the bottom end exit of the x-testing channel, the x-axis motor is used to drive the x-rotating shaft to drive the x-axis rotating frame to rotate and swing transversely at a preset angle and speed, so that the product in the x-testing channel rotates and swings transversely at a preset angle and speed accordingly, and the bottom end exit of the x-testing channel is used to connect with another testing platform, testing equipment, processing station or a conveying line or channel of an original production line.

[0006] Based on the above technical solution, the present invention achieves the following beneficial effects:

[0007] 1. The product only needs to slide in from the entrance at the top of the x test channel, and then use the x interception motor to drive the x interception shaft to drive the x interception block to swing into the lower end of the x test channel to limit the product from sliding out from the bottom exit of the x test channel. At this time, the inertial measurement unit of the product can be tested. After the test is completed, the x interception motor is used to drive the x interception shaft to drive the x interception block to move away from the lower end of the x test channel, so that the product can slide out from the bottom exit of the x test channel and flow into another test platform, test equipment, processing station or the conveyor line or channel of the original production line. Therefore, it is possible to send the product in and out of the test platform without setting up a loading and unloading mechanism, thereby reducing the preparation cost and occupied space of the equipment;

[0008] 2. Since there is no need for loading and unloading mechanisms to move the product to the test platform, the product only needs to slide through the x test channel to complete the lateral rotation and swing test of the inertial measurement unit, thereby simplifying the test steps and improving the test efficiency;

[0009] 3. When the product slides into the inclined x-test channel, the linear motion test of the product's inertial measurement unit can be completed. After that, the x-axis motor is used to drive the x-axis to drive the x-axis rotating frame to rotate and swing laterally at a preset angle and speed, so that the product in the x-test channel rotates and swings laterally at a preset angle and speed. In addition to simply testing the inertial measurement unit during linear motion, it can also test the lateral rotation and swinging motion, thereby increasing the measurement difficulty of the inertial measurement unit to more comprehensively inspect the inertial measurement unit.

[0010] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0011] In some embodiments, an x ​​clamping motor is also installed on the x-axis rotating frame, and the x clamping motor is transmission-connected to an x ​​clamping shaft, and an x ​​clamping block extends outward from the x clamping shaft. The x clamping motor is used to drive the x clamping shaft to drive the x clamping block to enter the upper end of the x test channel and approach the x intercepting block to clamp and fix the product in the x test channel.

[0012] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0013] 1. After the product slides into the x test channel, the x clamping motor drives the x clamping shaft to drive the x clamping block to enter the upper end of the x test channel and move close to the x intercepting block to clamp and fix the product in the x test channel, so that the x-axis motor drives the x-axis to drive the x-axis rotating frame to rotate and swing horizontally at a larger angle and faster speed, so that the inertial measurement unit of the product can be tested when the product rotates and swings horizontally or rotates at a larger angle and faster speed;

[0014] 2. When the product in the x test channel drives the product inside to rotate and swing horizontally, it can effectively avoid product displacement, thereby improving the test accuracy;

[0015] 3. When the product in the x-test channel drives the product inside to rotate and swing horizontally at a larger amplitude and speed, it can effectively prevent the product from leaving the x-test channel.

[0016] In some embodiments, an x-connecting flow channel is further installed on the x-axis test platform, the x-connecting flow channel is tilted downward and fixedly arranged, the downward tilt angle of the x-connecting flow channel is the same as the downward tilt angle of the x-test channel at the initial stage, and the top access port of the x-connecting flow channel is spliced ​​with the bottom outlet of the x-test channel, so that the product in the x-test channel can be sent to another platform, equipment, or workstation original production line through the x-connecting flow channel at a specific downward tilt. The conveyor line or channel connection;

[0017] Based on the above technical solution, after the x-test channel drives the product therein to rotate and swing horizontally, the product cannot absolutely return to the inclination angle before entering the x-test channel. At this time, when the product slides out from the exit of the x-test channel, the product is guided to a specific downward inclination through the x-connecting flow channel, so that the product can be more stably delivered to another platform, equipment, workstation or the conveyor line or channel connection of the original production line.

[0018] In some embodiments, an inertial measurement unit testing device further includes a y-axis testing platform. A y-axis motor is installed on the y-axis testing platform. The y-axis motor is drivingly connected to a horizontally arranged y-axis rotating shaft. A downwardly inclined y-axis rotating frame is fixed on the y-axis rotating shaft. The y-axis rotating frame is provided with a plurality of downwardly inclined y-test channels. The downward inclination angle of the y-test channels at the initial stage is the same as the downward inclination angle of the x connection channel. The top entrance position of the y-test channels is spliced with the bottom exit of the x connection channel, so that the products in the x connection channel can slide into the y-test channels. A y-intercept motor is installed on the y-axis rotating frame. The y-intercept motor is drivingly connected to a y-intercept rotating shaft. An outwardly extending y-intercept block is fixed on the y-intercept rotating shaft. The y-intercept motor is used to drive the y-intercept rotating shaft to drive the y-intercept block to swing into the lower part of the y-test channel to restrict the products from sliding out of the bottom exit of the y-test channel. The y-axis motor is used to drive the y-axis rotating shaft to drive the y-axis rotating frame to longitudinally rotate and swing at a preset angle and speed, so that the products in the y-test channels longitudinally rotate and swing at a preset angle and speed accordingly. The bottom exit of the y-test channels is used to connect to another testing platform, testing equipment, processing station, or the conveying line or channel of the original production line;

[0019] Based on the above technical solutions, the present invention further achieves the following beneficial effects:

[0020] 1. After the products in the x connection channel slide into from the top entrance position of the y-test channels, the y-intercept motor is used to drive the y-intercept rotating shaft to drive the y-intercept block to swing into the lower part of the y-test channel to restrict the products from sliding out of the bottom exit of the y-test channel. At this time, another item test of the inertial measurement unit of the product can be started. After completing this item test, the y-intercept motor is used to drive the y-intercept rotating shaft to drive the y-intercept block to move away from the lower part of the y-test channel. At this time, the products can flow from the bottom exit of the y-test channels into another testing platform, testing equipment, processing station, or the conveying line or channel of the original production line. Therefore, it is realized that there is no need to set up a loading and unloading mechanism to send the products into and out of this testing platform for another item test, thereby reducing the preparation cost and occupied space of the equipment;

[0021] 2. When the products slide into the y-test channels for testing, the y-axis motor is used to drive the y-axis rotating shaft to drive the y-axis rotating frame to longitudinally rotate and swing at a preset angle and speed, so that the products in the y-test channels longitudinally rotate and swing at a preset angle and speed accordingly, realizing further testing of the inertial measurement unit when adding a longitudinally rotating and swinging motion state, thereby relatively more comprehensively testing the inertial measurement unit.

[0022] In some embodiments, a y clamping motor is further installed on the y-axis rotating frame, the y clamping motor is drivingly connected to a y clamping shaft, a y clamping block extends outward from the y clamping shaft, and the y clamping motor is used to drive the y clamping shaft to drive the y clamping block to enter the upper end of the y test channel and approach the y interception block to clamp and fix the product in the y test channel;

[0023] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0024] 1. After the product slides into the y test channel, the y clamping motor is used to drive the y clamping shaft to drive the y clamping block to enter the upper end of the y test channel and move close to the y interception block to clamp and fix the product in the y test channel, so that the y-axis motor is used to drive the y rotating shaft to drive the y-axis rotating frame to rotate and swing longitudinally at a larger angle and faster speed, so that the inertial measurement unit of the product can be tested when the product rotates and swings longitudinally or rotates at a larger angle and faster speed;

[0025] 2. When the product in the Y test channel drives the product inside to rotate and swing longitudinally, it can effectively avoid product displacement, thereby improving the test accuracy;

[0026] 3. When the product in the y test channel drives the product inside to perform longitudinal rotation and swing at a larger amplitude and speed, it can effectively prevent the product from leaving the y test channel.

[0027] In some embodiments, a y-connecting flow channel is further installed on the y-axis test platform, the y-connecting flow channel is tilted downward and fixedly arranged, the downward tilt angle of the y-connecting flow channel is the same as the downward tilt angle of the y-test channel at the initial stage, and the top access port of the y-connecting flow channel is spliced ​​with the bottom outlet of the y-test channel, so that the product in the y-test channel can be sent to the conveying line or channel connection of another platform, equipment or workstation through the y-connecting flow channel at a specific downward tilt;

[0028] Based on the above technical solution, after the y test channel drives the product therein to rotate and swing horizontally, the product cannot absolutely return to the inclination angle before entering the y test channel. At this time, when the product slides out of the exit of the y test channel, the product is adjusted to a specific downward inclination through the y connecting flow channel, so that the product can be more stably delivered to another platform, equipment, workstation or the conveyor line or channel connection of the original production line.

[0029] In some embodiments, an inertial measurement unit testing device further includes a climbing platform. A climbing conveyor line is installed on the climbing platform. The inlet end of the climbing conveyor line is horizontally arranged and spliced with the outlet at the bottom end of the y connection channel. The latter half of the climbing conveyor line is inclined upward. The outlet of the climbing conveyor line is located at the top. After the product enters the climbing conveyor line from the y connection channel, the climbing conveyor line drives the product to rise back to the height for entering the x testing channel. A flow bar is spliced at the outlet of the climbing conveyor line. Guide blocks are arranged on both sides of the flow bar. The guide blocks are located at the outlet of the climbing conveyor line. An outlet blocking mechanism is arranged at the end of the flow bar. The end of the flow bar is used to connect with another testing platform, testing equipment, processing station, or the conveyor line or channel of the original production line;

[0030] Based on the above technical solutions, the present invention further achieves the following beneficial effects:

[0031] 1. Since the x testing channel, y testing channel, x connection channel, and y connection channel are all inclined downward, when the product flows out of the y connection channel, the height of the product is lower than the height before flowing into the x testing channel from the production line conveyor. At this time, the product flowing out of the y connection channel can flow into the horizontal part of the climbing conveyor line, and the climbing conveyor line transfers the product to the upwardly inclined latter half of the climbing conveyor line. At this time, the latter half of the climbing conveyor line drives the product to rise until the product returns to the height before flowing into the x testing channel, thus facilitating the transportation of the product to another testing device, processing station, or the conveyor line or channel of the original production line;

[0032] 2. After the product returns to the height before flowing into the x testing channel through the climbing conveyor line, the product flows into the flow bar from the outlet of the climbing conveyor line. At this time, the outlet blocking mechanism intermittently blocks the product in the flow bar from being pushed out, thereby controlling the frequency of the product flowing into another testing platform, testing equipment, processing station, or the conveyor line or channel of the original production line.

[0033] In some embodiments, an inertial measurement unit testing device further includes a carrier for placing and fixing a product. The carrier is provided with a rigid light-transmitting plate, and a soft light-transmitting film is disposed above the rigid light-transmitting plate. A gap is provided between the rigid light-transmitting plate and the soft light-transmitting film. The soft light-transmitting film is provided with a coating film for adhering a certain point position or several point positions to the rigid light-transmitting plate through static electricity, friction or tension. The x-axis rotating frame is provided with a light source and a photosensor. The x test channel is located between the light source and the photosensor. When the carrier is located in the x test channel, the light emitted by the light source can pass through the rigid light-transmitting plate and the soft light-transmitting film and irradiate the photosensor. When the light passes through the rigid light-transmitting plate and the soft light-transmitting film, due to the gap between the soft light-transmitting film and the rigid light-transmitting plate, the soft light-transmitting film and the rigid light-transmitting plate scatter the light, and the light can be directly irradiated at the joint part of the soft light-transmitting film and the rigid light-transmitting plate, so that the developed image of the rigid light-transmitting plate irradiates the photosensor. The photosensor registers or obtains the product information in the carrier through the images distributed at different positions or quantities;

[0034] Based on the above technical solutions, the present invention further achieves the following beneficial effects:

[0035] 1. Since a gap is provided between the rigid light-transmitting plate and the soft light-transmitting film, and at the same time, a certain point position or several point positions of the soft light-transmitting film are adhered to the rigid light-transmitting plate, when the light emitted by the light source can pass through the rigid light-transmitting plate and the soft light-transmitting film and irradiate the photosensor, due to the gap between the soft light-transmitting film and the rigid light-transmitting plate, the soft light-transmitting film and the rigid light-transmitting plate scatter the light, and the light can be directly irradiated at the joint part of the soft light-transmitting film and the rigid light-transmitting plate, so that the developed image of the rigid light-transmitting plate irradiates the photosensor. At this time, by adhering different positions and different areas of the soft light-transmitting film to the rigid light-transmitting plate on different carriers, images with different positions and areas can be developed on the rigid light-transmitting plate. At this time, the photosensor obtains and registers the product information in the carrier through the images distributed at different positions and areas;

[0036] 2. Since the carriers are generally recycled, when the carrier is replaced to store another product, because the soft light-transmitting film is adhered to the rigid light-transmitting plate through the coating film by static electricity, friction or tension, the adhered part of the soft light-transmitting film and the rigid light-transmitting plate can be separated. At this time, the position and area of the soft light-transmitting film adhered to the rigid light-transmitting plate can be changed according to the other product, so as to reset the information identification mark of the carrier;

[0037] 3. Since the x-axis rotating frame rotates around the x-axis, that is, the rotation stroke of each x test channel on the x-axis rotating frame is different, the lateral rotation and swinging motion strokes of the products in each x test channel are also different, that is, the values ​​measured by the inertial measurement unit in each x test channel are also different. Therefore, by obtaining the product information in the x test channel and registering the rotation stroke of the product, the accuracy and authenticity of the test can be improved.

[0038] In some embodiments, an information editing channel is independently arranged in front of the entrance of each x-test channel, so that a carrier with a product placed thereon enters the x-test channel and passes through the information editing channel in advance and temporarily stays in the information editing channel. A pressing power module is arranged in each information editing channel, and each pressing power module drives a pressing block for pressing down on the soft light-transmitting film. The pressing block is distributed with a plurality of pressing points for pushing a certain point of the soft light-transmitting film to fit with the hard light-transmitting plate. The distribution position and area of ​​the pressing points on any pressing block are different from those of the pressing points of the other pressing blocks.

[0039] Based on the above technical solution, before the carrier supporting the product enters the x-test channel, it passes through the information editing channel in advance. At this time, the downward pressure power module in the information editing channel is used to drive the pressure block to press down on the soft light-transmitting film, and the pressure point of the pressure block pushes a certain point of the soft light-transmitting film to fit with the hard light-transmitting plate, thereby realizing the editing of the information identification mark of the carrier for the x-test channel it is about to enter.

[0040] In some embodiments, the carrier is provided with a slide groove, in which a slide rod that can slide between the hard light-transmitting plate and the soft light-transmitting film slides, the slide groove is provided with a spring for pulling the slide rod to one end, and the information editing channel is fixedly provided with a push rod located in front of the downward pressing power module, and the carrier moves in the information editing channel to the front of the downward pressing power module, and the push rod pushes the slide rod to move to the other end of the slide groove, so that the slide rod separates the part where the soft light-transmitting film and the hard light-transmitting plate are attached, and an upward sliding slope is provided at the other end of the slide groove, so that when the slide rod is pushed to the other end of the slide groove by the push rod, the slide rod slides up to the upper sliding slope and rises over the push rod, and at this time, the spring pulls the slide rod to reset;

[0041] Based on the above technical solution, the present invention achieves the following beneficial effects:

[0042] 1. Before the pressing power module in the information editing channel is used to drive the pressing block to press down onto the soft light-transmitting film, in the process of moving the carrier to the position of the pressing power module through the information editing channel, the sliding rod is pushed to the other end of the sliding groove by a fixed push rod, so that the sliding rod separates the part where the soft light-transmitting film and the hard light-transmitting plate are attached, thereby realizing automatic resetting of the information identification mark of the carrier;

[0043] 2. When the slide bar moves to the other end of the chute, the rod slides up the upper inclined plane and crosses the push rod, causing the spring to pull the slide bar back to one end of the chute, thus achieving reset. Brief Description of the Drawings

[0060] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, this detailed implementation manner further describes the present invention in detail with reference to the accompanying drawings.

[0061] As Figures 1 to 8 shown, this detailed implementation manner provides an inertial measurement unit testing device, which includes an x-axis testing platform 1. An x-axis motor 11 is installed on the x-axis testing platform 1. The x-axis motor 11 is drivingly connected to a longitudinally arranged x-axis rotating shaft 12. An x-axis rotating frame 13 that is inclined downward is fixed on the x-axis rotating shaft 12. A plurality of x-test channels 14 that are inclined downward are provided on the x-axis rotating frame 13. The inlet at the top end of the x-test channel 14 is connected to the production line, so that the production line can send the products placed thereon into the x-test channel 14. An x-intercepting motor 15 is installed on the x-axis rotating frame 13. The x-intercepting motor 15 is drivingly connected to an x-intercepting rotating shaft 16. An outwardly extending x-intercepting block 161 is fixed on the x-intercepting rotating shaft 16. The x-intercepting motor 15 is used to drive the x-intercepting rotating shaft 16 to drive the x-intercepting block 161 to swing into the lower end part of the x-test channel 14 to limit the products from sliding out from the bottom outlet of the x-test channel 14. The x-axis motor 11 is used to drive the x-axis rotating shaft 12 to drive the x-axis rotating frame 13 to horizontally rotate and swing at a preset angle and speed, so that the products in the x-test channel 14 will horizontally rotate and swing at a preset angle and speed accordingly. The bottom outlet of the x-test channel 14 is used to be connected to another testing platform, testing equipment, processing station or the conveyor line or channel of the original production line.

[0062] The product only needs to slide in from the entrance at the top of the x-test channel 14, and then use the x-interception motor 15 to drive the x-interception shaft 16 to drive the x-interception block 161 to swing into the lower end of the x-test channel 14 to limit the product from sliding out from the bottom exit of the x-test channel 14. At this time, the inertial measurement unit of the product can be tested. After the test is completed, use the x-interception motor 15 to drive the x-interception shaft 16 to drive the x-interception block 161 to move away from the lower end of the x-test channel 14, so that the product can slide out from the bottom exit of the x-test channel 14 and flow into another test platform, test equipment, processing station or the conveyor line or channel of the original production line. Therefore, the product can be sent in and out of the test platform without setting up a loading and unloading mechanism, thereby reducing the preparation cost of the equipment and the occupied space.

[0063] Since there is no need for a loading and unloading mechanism to move the product to the test platform, the product only needs to slide through the x test channel 14 to complete the lateral rotation and swing test of the inertial measurement unit, thereby simplifying the test steps and improving the test efficiency.

[0064] When the product slides into the inclined x-test channel 14, the linear motion test of the product's inertial measurement unit can be completed. After that, the x-axis motor 11 is used to drive the x-axis shaft 12 to drive the x-axis rotating frame 13 to rotate and swing laterally at a preset angle and speed, so that the product in the x-test channel 14 rotates and swings laterally at a preset angle and speed. In addition to simply testing the inertial measurement unit during linear motion, it is also possible to test the lateral rotation and swinging motion, thereby increasing the measurement difficulty of the inertial measurement unit and more comprehensively inspecting the inertial measurement unit.

[0065] When the product is being tested, the product can record and store the data obtained by the inertial measurement unit through its own storage unit and processor, and finally compare the information stored in the storage unit of the product with the driving information used in the test on the production line, thereby inspecting the inertial measurement unit of the product.

[0066] In some embodiments, an x ​​clamping motor 17 is also installed on the x-axis rotating frame 13, and the x clamping motor 17 is transmission-connected to an x ​​clamping shaft 18, and an x ​​clamping block 181 extends outward from the x clamping shaft 18. The x clamping motor 17 is used to drive the x clamping shaft 18 to drive the x clamping block 181 to enter the upper end of the x test channel 14 and approach the x intercepting block 161 to clamp and fix the product in the x test channel 14.

[0067] After the product slides into the x test channel 14, the x clamping motor 17 is used to drive the x clamping shaft 18 to drive the x clamping block 181 to enter the upper end of the x test channel 14 and move close to the x intercepting block 161 to clamp and fix the product in the x test channel 14, so that the x-axis motor 11 is used to drive the x rotating shaft 12 to drive the x-axis rotating frame 13 to rotate and swing horizontally at a larger angle and faster speed, so that the inertial measurement unit of the product can be tested when the product rotates and swings horizontally or rotates at a larger angle and faster speed. When the product drives the product in the x test channel 14 to rotate and swing horizontally, it can effectively avoid the product from shifting, thereby improving the test accuracy. In addition, when the product drives the product in the x test channel 14 to rotate and swing horizontally at a larger amplitude and speed, it can effectively avoid the product from leaving the x test channel 14.

[0068] In some embodiments, an x-connecting channel 19 is also installed on the x-axis test platform 1. The x-connecting channel 19 is tilted downward and fixedly arranged. The downward tilt angle of the x-connecting channel 19 is the same as the downward tilt angle of the x-test channel 14 in the initial stage. The top access port of the x-connecting channel 19 is spliced ​​with the bottom outlet of the x-test channel 14, so that the product in the x-test channel 14 can be delivered to another platform, equipment, or workstation production line through the x-connecting channel 19 at a specific downward inclination. Conveyor line or channel connection.

[0069] After the x-test channel 14 drives the product therein to rotate and swing horizontally, the product cannot absolutely return to the inclination angle before entering the x-test channel 14. At this time, when the product slides out from the exit of the x-test channel 14, the product is guided to a specific downward inclination through the x-connecting flow channel 19, so that the product can be more stably delivered to another platform, equipment, workstation or the conveyor line or channel connection of the original production line.

[0070] In some embodiments, an inertial measurement unit testing device further includes a y-axis testing platform 2. A y-axis motor 21 is installed on the y-axis testing platform 2. The y-axis motor 21 is drivingly connected to a horizontally arranged y-axis rotating shaft 22. A downwardly inclined y-axis rotating frame 23 is fixed on the y-axis rotating shaft 22. The y-axis rotating frame 23 is provided with a plurality of downwardly inclined y-test channels 24. The downward inclination angle of the y-test channels 24 at the initial stage is the same as the downward inclination angle of the x connection channel 19. The top entrance position of the y-test channels 24 is spliced with the bottom exit of the x connection channel 19, so that the products in the x connection channel 19 can slide into the y-test channels 24. A y-intercepting motor 25 is installed on the y-axis rotating frame 23. The y-intercepting motor 25 is drivingly connected to a y-intercepting rotating shaft 26. An outwardly extending y-intercepting block 261 is fixed on the y-intercepting rotating shaft 26. The y-intercepting motor 25 is used to drive the y-intercepting rotating shaft 26 to drive the y-intercepting block 261 to swing into the lower part of the y-test channels 24 to limit the products from sliding out of the bottom exit of the y-test channels 24. The y-axis motor 21 is used to drive the y-axis rotating shaft 22 to drive the y-axis rotating frame 23 to longitudinally rotate and swing at a preset angle and speed, so that the products in the y-test channels 24 longitudinally rotate and swing at a preset angle and speed accordingly. The bottom exit of the y-test channels 24 is used to connect to the conveying line or channel of another testing platform, testing equipment, processing station or the original production line.

[0071] After the products in the x connection channel 19 slide into the y-test channels 24 from the top entrance position, the y-intercepting motor 25 is used to drive the y-intercepting rotating shaft 26 to drive the y-intercepting block 261 to swing into the lower part of the y-test channels 24 to limit the products from sliding out of the bottom exit of the y-test channels 24. At this time, another item test of the inertial measurement unit of the product can be started. After completing this item test, the y-intercepting motor 25 is used to drive the y-intercepting rotating shaft 26 to drive the y-intercepting block 261 to move away from the lower part of the y-test channels 24. At this time, the products can flow into the conveying line or channel of another testing platform, testing equipment, processing station or the original production line from the bottom exit of the y-test channels 24. Therefore, it is realized that the products can be sent into and out of this testing platform for another item test without setting up a loading and unloading mechanism, thereby reducing the preparation cost and occupied space of the equipment.

[0072] When the products slide into the y-test channels 24 for testing, the y-axis motor 21 is used to drive the y-axis rotating shaft 22 to drive the y-axis rotating frame 23 to longitudinally rotate and swing at a preset angle and speed, so that the products in the y-test channels 24 longitudinally rotate and swing at a preset angle and speed accordingly, realizing further testing of the inertial measurement unit when adding a longitudinally rotating and swinging motion state, and thus relatively more comprehensively testing the inertial measurement unit.

[0073] In some embodiments, a y - clamping motor 27 is further installed on the y - axis rotating frame 23. The y - clamping motor 27 is drivingly connected to a y - clamping shaft 28. A y - clamping block 281 extends outwardly on the y - clamping shaft 28. The y - clamping motor 27 is used to drive the y - clamping shaft 28 to drive the y - clamping block 281 into the upper part of the y - test channel 24 and approach the y - intercepting block 261, so as to clamp and fix the product in the y - test channel 24.

[0074] After the product slides into the y - test channel 24, the y - clamping motor 27 is used to drive the y - clamping shaft 28 to drive the y - clamping block 281 into the upper part of the y - test channel 24 and approach the y - intercepting block 261, so as to clamp and fix the product in the y - test channel 24, enabling the y - axis motor 21 to drive the y - rotating shaft 22 to drive the y - axis rotating frame 23 to longitudinally rotate and swing at a larger angle and faster speed, so as to test the inertial measurement unit of the product when it longitudinally rotates and swings or rotates at a larger angle and faster speed. When the product longitudinally rotates and swings in the y - test channel 24, it can effectively prevent the product from shifting, thereby improving the test accuracy rate; in addition, when the product longitudinally rotates and swings in the y - test channel 24 at a larger amplitude and speed, it can effectively prevent the product from detaching from the y - test channel 24.

[0075] In some embodiments, a y - connection flow channel 29 is further installed on the y - axis test platform 2. The y - connection flow channel 29 is inclined downward and fixedly arranged. The downward inclination angle of the y - connection flow channel 29 is the same as the downward inclination angle of the y - test channel 24 in the initial stage. The top inlet of the y - connection flow channel 29 is spliced with the bottom outlet of the y - test channel 24, so that the product in the y - test channel 24 can be sent to the conveying line or channel connection of another platform, device or work - station at a specific downward inclination through the y - connection flow channel 29.

[0076] After the product laterally rotates and swings in the y - test channel 24, the product cannot absolutely return to the inclination angle before entering the y - test channel 24. At this time, when the product slides out of the outlet of the y - test channel 24, the y - connection flow channel 29 adjusts the product to a specific downward inclination, so that the product can be more stably sent to the conveying line or channel connection of another platform, device, work - station or the original production line.

[0077] In some embodiments, an inertial measurement unit testing device further includes a climbing platform 3. The climbing platform 3 is equipped with a climbing conveyor line 31. The inlet end of the climbing conveyor line 31 is horizontally arranged and spliced with the outlet at the bottom end of the y connecting channel 29. The latter half of the climbing conveyor line 31 is inclined upward. The outlet of the climbing conveyor line 31 is located at the top. After the product enters the climbing conveyor line 31 from the y connecting channel 29, the climbing conveyor line 31 drives the product to rise back to the height for entering the x testing channel 14. A flow bar 32 is spliced at the outlet of the climbing conveyor line 31. Guide blocks are arranged on both sides of the flow bar 32, and the guide blocks are located at the outlet of the climbing conveyor line 31. An outlet blocking mechanism 33 is arranged at the end of the flow bar 32. The outlet blocking mechanism 33 can drive a blocking block to move to the end of the flow bar 32 by a cylinder to achieve blocking. The end of the flow bar 32 is used to connect to another testing platform, testing equipment, processing station, or the conveyor line or channel of the original production line.

[0078] Since the x testing channel 14, y testing channel 24, x connecting channel 19, and y connecting channel 29 are all inclined downward, when the product flows out from the y connecting channel 29, the height of the product is lower than the height before flowing into the x testing channel 14 from the production line conveyor. At this time, the product flowing out from the y connecting channel 29 can flow into the horizontal part of the climbing conveyor line 31, enabling the climbing conveyor line 31 to transfer the product to the upwardly inclined latter half of the climbing conveyor line 31. At this time, the latter half of the climbing conveyor line 31 drives the product to rise until the product returns to the height before flowing into the x testing channel 14, thus facilitating the transportation of the product to another testing device, processing station, or the conveyor line or channel of the original production line.

[0079] After the product returns to the height before flowing into the x testing channel 14 through the climbing conveyor line 31, the product flows into the flow bar 32 from the outlet of the climbing conveyor line 31. At this time, the outlet blocking mechanism 33 controls the frequency of the product flowing into another testing platform, testing equipment, processing station, or the conveyor line or channel of the original production line by intermittently blocking the product in the flow bar 32 from being pushed out.

[0080] In some embodiments, an inertial measurement unit testing device further includes a carrier 4 for placing and fixing a product. The carrier 4 is provided with a rigid light-transmitting plate 41, and a soft light-transmitting film 42 is disposed above the rigid light-transmitting plate 41. A gap is provided between the rigid light-transmitting plate 41 and the soft light-transmitting film 42. The soft light-transmitting film 42 is provided with a coating 43 for adhering a certain point position or several point positions to the rigid light-transmitting plate 41 through static electricity, friction or tension. The x-axis rotating frame 13 is provided with a light source 6 and a photosensor 61. The x test channel 14 is located between the light source 6 and the photosensor 61. When the carrier 4 is located in the x test channel 14, the light 62 emitted by the light source 6 can pass through the rigid light-transmitting plate 41 and the soft light-transmitting film 42 and irradiate the photosensor 61. When the light 62 passes through the rigid light-transmitting plate 41 and the soft light-transmitting film 42, due to the gap between the soft light-transmitting film 42 and the rigid light-transmitting plate 41, the soft light-transmitting film 42 and the rigid light-transmitting plate 41 disperse the light 62, and the joint part of the soft light-transmitting film 42 and the rigid light-transmitting plate 41 can directly irradiate the light 62, so that the developed image 44 on the rigid light-transmitting plate 41 irradiates the photosensor 61. The photosensor 61 registers or obtains the product information in the carrier 4 through the images 44 distributed at different positions or in different quantities.

[0081] Since a gap is provided between the rigid light-transmitting plate 41 and the soft light-transmitting film 42, and at the same time, a certain point position or several point positions of the soft light-transmitting film 42 are adhered to the rigid light-transmitting plate 41, when the light 62 emitted by the light source 6 can pass through the rigid light-transmitting plate 41 and the soft light-transmitting film 42 and irradiate the photosensor 61, due to the gap between the soft light-transmitting film 42 and the rigid light-transmitting plate 41, the soft light-transmitting film 42 and the rigid light-transmitting plate 41 disperse the light 62, and the joint part of the soft light-transmitting film 42 and the rigid light-transmitting plate 41 can directly irradiate the light 62, so that the developed image 44 on the rigid light-transmitting plate 41 irradiates the photosensor 61. At this time, by adhering different positions and different areas of the soft light-transmitting film 42 to the rigid light-transmitting plate 41 on different carriers 4, images 44 with different positions and areas can be developed on the rigid light-transmitting plate 41. At this time, the photosensor 61 obtains and registers the product information in the carrier 4 through the images 44 distributed at different positions and areas.

[0082] Since the carriers 4 are generally recycled, when the carrier 4 is replaced to store another product, since the soft light-transmitting film 42 is adhered to the rigid light-transmitting plate 41 through the coating 43 by static electricity, friction or tension, the joint part of the soft light-transmitting film 42 and the rigid light-transmitting plate 41 can be separated. At this time, the position and area of the soft light-transmitting film 42 adhered to the rigid light-transmitting plate 41 can be changed according to another product, so as to reset the information identification mark of the carrier 4;

[0083] Since the x-axis rotating frame 13 rotates around the x-axis rotating shaft 12, that is, the rotation strokes of each x-test channel 14 on the x-axis rotating frame 13 are different, and the lateral rotation and swing strokes between the products in each x-test channel 14 are also different from each other. That is, the values measured by the inertial measurement units in each x-test channel 14 are also different from each other. Therefore, by obtaining the product information in the x-test channel 14 and registering the rotation stroke of the product, the accuracy and authenticity of the test are improved.

[0084] In some embodiments, an information editing channel 5 is independently provided in front of the entrance of each x-test channel 14, so that the carrier 4 carrying the product enters the x-test channel 14 after passing through the information editing channel 5 in advance and stays in the information editing channel 5 temporarily. Each information editing channel 5 is provided with a downward pressing power module 51, and each downward pressing power module 51 drives a pressing block 52 for pressing down on the soft light-transmitting film 42. The pressing block 52 is distributed with a number of pressing points 53 for pushing a certain point position of the soft light-transmitting film 42 to fit with the hard light-transmitting plate 41. The distribution positions and areas of the pressing points 53 on any one pressing block 52 are different from those of the pressing points 53 on the other pressing blocks 52.

[0085] Before the carrier 4 supporting the product enters the x-test channel 14, it passes through the information editing channel 5 in advance. At this time, the downward pressing power module 51 in the information editing channel 5 drives the pressing block 52 to press down on the soft light-transmitting film 42, and the pressing points 53 of the pressing block 52 push a certain point position of the soft light-transmitting film 42 to fit with the hard light-transmitting plate 41, so as to realize editing the information identification mark of the x-test channel 14 that the carrier 4 is about to enter.

[0086] In some embodiments, the carrier 4 is provided with a sliding groove 45, and a sliding rod 46 that can slide between the hard light-transmitting plate 41 and the soft light-transmitting film 42 slides in the sliding groove 45. The sliding groove 45 is provided with a spring 48 for pulling the sliding rod 46 to one end. The information editing channel 5 is fixedly provided with a push rod 54 in front of the downward pressing power module 51. When the carrier 4 moves in the information editing channel 5 to the front of the downward pressing power module 51, the push rod 54 pushes the sliding rod 46 to move to the other end of the sliding groove 45, so that the sliding rod 46 separates the part where the soft light-transmitting film 42 is attached to the hard light-transmitting plate 41. The other end of the sliding groove 45 is provided with an upward sliding inclined surface 47, so that when the sliding rod 46 is pushed by the push rod 54 to the other end of the sliding groove 45, the sliding rod 46 slides up the upward sliding inclined surface 47 and crosses the push rod 54. At this time, the spring 48 pulls the sliding rod 46 to reset.

[0087] The pressing power module 51 within the information editing channel 5 is used to drive the pressing block 52 to press down onto the soft light-transmitting film 42. During the process of moving the carrier 4 to the position where the pressing power module 51 is located through the information editing channel 5, the fixedly arranged push rod 54 is utilized to push the sliding rod 46 to move to the other end of the sliding groove 45, causing the part where the soft light-transmitting film 42 is attached to the hard light-transmitting plate 41 to be separated, thereby realizing the automatic reset of the information recognition mark of the carrier 4; when the sliding rod 46 moves to the other end of the sliding groove 45, the rod slides up along the upward-sloping surface 47 and crosses over the push rod 54, enabling the spring 48 to pull the sliding rod 46 back to one end of the sliding groove 45, thus realizing the reset.

[0088] In order to further illustrate the inertial measurement unit testing device described in this specific embodiment, the following embodiments are listed. Embodiment

[0091] An x-axis motor 11 and an x connection flow channel 19 are installed on the x-axis testing platform 1. The x-axis motor 11 is drivingly connected to a longitudinally arranged x-axis rotating shaft 12, and an x-axis rotating frame 13 that is inclined downward is fixed on the x-axis rotating shaft 12. The x-axis rotating frame 13 is provided with a plurality of x testing channels 14 that are inclined downward.

The top connection port of the x connection flow channel 19 is spliced with the bottom outlet of the x testing channel 14, so that the product in the x testing channel 14 can be sent into the conveying line or channel connection of another platform, device, or work station at a specific downward inclination through the x connection flow channel 19.

[0092] An x-intercept motor 15 and an x-clamping motor 17 are installed on the x-axis rotating frame 13. The x-intercept motor 15 is drivingly connected to an x-intercept rotating shaft 16. An outwardly extending x-intercept block 161 is fixed on the x-intercept rotating shaft 16. The x-intercept motor 15 drives the x-intercept rotating shaft 16 to drive the x-intercept block 161 to swing into the lower end part of the x-test channel 14 to restrict the product from sliding out of the bottom outlet of the x-test channel 14. The x-clamping motor 17 is drivingly connected to an x-clamping shaft 18. An outwardly extending x-clamping block 181 is provided on the x-clamping shaft 18.

[0093] The following is the working description of an inertial measurement unit testing device according to this embodiment.

[0094] During the process of the product on the production line sliding into the x-test channel 14 from the inlet at the top, the inertial measurement unit of the product is tested in a linear motion state. After the product on the production line slides into the x-test channel 14 from the inlet at the top, the x-intercept motor 15 drives the x-intercept rotating shaft 16 to drive the x-intercept block 161 to swing into the lower end part of the x-test channel 14 to restrict the product from sliding out of the bottom outlet of the x-test channel 14. At the same time, the x-clamping motor 17 drives the x-clamping shaft 18 to drive the x-clamping block 181 to enter the upper end part of the x-test channel 14 and approach the x-intercept block 161 to clamp and fix the product in the x-test channel 14. Thereafter, the x-axis motor 11 drives the x-rotating shaft 12 to drive the x-axis rotating frame 13 to horizontally rotate and swing at a preset angle and speed, so that the product in the x-test channel 14 rotates and swings horizontally at a preset angle and speed to test the state during the horizontal rotation and swing motion. Thereafter, the x-clamping motor 17 drives the x-clamping shaft 18 to drive the x-clamping block 181 to move away from the upper end part of the x-test channel 14 and approach the x-intercept block 161, and the x-intercept motor 15 drives the x-intercept rotating shaft 16 to drive the x-intercept block 161 to move away from the lower end part of the x-test channel 14. At this time, when the product slides out of the x-test channel 14, the product is guided and adjusted to a specific downward inclination through the x-transfer channel 19 and flows into the conveying line or channel connection of another platform, device, station or the original production line.

[0102] The following is the working description of the inertial measurement unit test device according to this embodiment.

[0103] During the process of the product on the production line sliding into the inlet at the top end of the x-test channel 14, the inertial measurement unit of the product is tested in the straight-line motion state.

[0104] After the product on the production line slides into the entrance at the top of the x test channel 14, the x interception motor 15 drives the x interception shaft 16 to drive the x interception block 161 to swing into the lower end of the x test channel 14 to limit the product from sliding out of the bottom exit of the x test channel 14. At the same time, the x clamping motor 17 drives the x clamping shaft 18 to drive the x clamping block 181 to enter the upper end of the x test channel 14 and move close to the x interception block 161 to clamp and fix the product in the x test channel 14. Thereafter, the x-axis motor 11 drives the x-axis shaft 12 to drive the x-axis rotating frame 13 to rotate and swing horizontally at a preset angle and speed. , so that the product in the x test channel 14 rotates and swings laterally at a preset angle and speed, and tests the state during the lateral rotation and swinging movement; after completing the test, the x clamping motor 17 drives the x clamping shaft 18 to drive the x clamping block 181 to move away from the upper end of the x test channel 14 and move closer to the x intercepting block 161, and the x intercepting motor 15 drives the x intercepting shaft 16 to drive the x intercepting block 161 to move away from the lower end of the x test channel 14. At this time, when the product slides out of the outlet of the x test channel 14, the product is guided and adjusted to a specific downward inclination through the x connecting flow channel 19 to flow into the y test channel 24.

[0105] Afterwards, the y interception motor 25 is used to drive the y interception shaft 26 to drive the y interception block 261 to swing into the lower end of the y test channel 24 to limit the product from sliding out of the bottom end outlet of the y test channel 24. At the same time, the y clamping motor 27 drives the y clamping shaft 28 to drive the y clamping block 281 to enter the upper end of the y test channel 24 and move closer to the y interception block 261 to clamp and fix the product in the y test channel 24. Afterwards, the y-axis motor 21 drives the y-axis 22 to drive the y-axis rotating frame 23 to rotate and swing longitudinally at a preset angle and speed, so that the product in the y test channel 24 The product then rotates and swings laterally at a preset angle and speed to test its state during the lateral rotation and swinging movement; after the test is completed, the y clamping motor 27 drives the y clamping shaft 28 to drive the y clamping block 281 to move away from the upper end of the y test channel 24 and approach the y interception block 261, and the y interception motor 25 drives the y interception shaft 26 to drive the y interception block 261 to move away from the lower end of the y test channel 24. At this time, when the product slides out of the outlet of the y test channel 24, the product is guided and adjusted to a specific downward inclination through the y connecting flow channel 29 to flow into the climbing conveyor line 31.

[0106] Thereafter, the uphill conveyor line 31 transfers the product to the upwardly inclined rear half of the uphill conveyor line 31. At this time, the rear half of the uphill conveyor line 31 drives the product to rise until the product returns to the height before flowing into the x-test channel 14. Thereafter, the product flows into the flow bar 32 from the outlet of the uphill conveyor line 31. At this time, the discharge blocking mechanism 33 controls the frequency of the product flowing into the conveyor line or channel of another test platform, test equipment, processing station, or the original production line by intermittently blocking the product in the flow bar 32 from being pushed out. Embodiment

[0107] As Figures 1 to 8 shown, this embodiment provides an inertial measurement unit testing device, which includes the technical solutions of Embodiment 1 or 2. At the same time, it further includes the following features.

[0108] The carrier 4 is provided with a rigid light-transmitting plate 41. Above the rigid light-transmitting plate 41, a soft light-transmitting film 42 is provided. A gap is provided between the rigid light-transmitting plate 41 and the soft light-transmitting film 42. The soft light-transmitting film 42 is provided with a coating film 43 for bonding a certain point position or several point positions to the rigid light-transmitting plate 41 through static electricity, friction, or tension. The x-axis rotating frame 13 is provided with a light source 6 and a light sensor 61. The x-test channel 14 is located between the light source 6 and the light sensor 61. When the carrier 4 is located in the x-test channel 14, the light 62 emitted by the light source 6 can pass through the rigid light-transmitting plate 41 and the soft light-transmitting film 42 and irradiate the light sensor 61. When the light 62 passes through the rigid light-transmitting plate 41 and the soft light-transmitting film 42, due to the gap between the soft light-transmitting film 42 and the rigid light-transmitting plate 41, the soft light-transmitting film 42 and the rigid light-transmitting plate 41 scatter the light 62, and the bonded part of the soft light-transmitting film 42 and the rigid light-transmitting plate 41 can directly irradiate the light 62, so that the developed image 44 of the rigid light-transmitting plate 41 irradiates the light sensor 61, and the light sensor 61 registers or obtains the product information in the carrier 4 through the images 44 distributed at different positions or areas.

[0109] An information editing channel 5 is independently provided in front of the entrance of each x-test channel 14, so that the carrier 4 with the product enters the x-test channel 14 and passes through the information editing channel 5 in advance and stays temporarily in the information editing channel 5. Each information editing channel 5 is provided with a downward pressing power module 51, and each downward pressing power module 51 drives a pressing block 52 for pressing down on the soft light-transmitting film 42. The pressing block 52 is distributed with a number of pressing points 53 for pushing a certain point position of the soft light-transmitting film 42 to fit with the rigid light-transmitting plate 41. The distribution positions and areas of the pressing points 53 on any one pressing block 52 are different from those of the pressing points 53 of the other pressing blocks 52.

[0110] The vehicle 4 is provided with a chute 45, and a slide bar 46 that can slide between the rigid light-transmitting plate 41 and the flexible light-transmitting film 42 slides in the chute 45. The chute 45 is provided with a spring 48 for pulling the slide bar 46 to one end. The information editing channel 5 is fixedly provided with a push rod 54 in front of the downward pressing power module 51. When the vehicle 4 moves into the information editing channel 5 to the front of the downward pressing power module 51, the push rod 54 pushes the slide bar 46 to move to the other end of the chute 45, so that the slide bar 46 separates the part where the flexible light-transmitting film 42 is attached to the rigid light-transmitting plate 41. The other end of the chute 45 is provided with an upward sliding inclined surface 47, so that when the slide bar 46 is pushed by the push rod 54 to the other end of the chute 45, the slide bar 46 slides up the upward sliding inclined surface 47 and rises above the push rod 54. At this time, the spring 48 pulls the slide bar 46 to reset.

[0111] The following is the working process of an inertial measurement unit testing device according to this embodiment.

[0112] Before the vehicle 4 carrying the product enters the x-test channel 14, it passes through the information editing channel 5 in advance. During the movement of the vehicle 4 through the information editing channel 5, the fixedly arranged push rod 54 is used to push the slide bar 46 to move from the left end to the right end of the chute 45, so that the slide bar 46 separates the part where the flexible light-transmitting film 42 is attached to the rigid light-transmitting plate 41, thereby realizing the automatic reset of the information identification mark of the vehicle 4; when the slide bar 46 moves to the right end of the chute 45, the rod slides up the upward sliding inclined surface 47 and rises above the push rod 54, and the spring 48 pulls the slide bar 46 back to the left end of the chute 45 to reset; thereafter, the information editing channel 5 moves the vehicle 4 to the position corresponding to the downward pressing power module 51. At this time, the information editing channel 5 pauses the movement of the vehicle 4, and the downward pressing power module 51 drives the pressing block 52 to press down on the flexible light-transmitting film 42. The pressing point 53 of the pressing block 52 pushes a certain position of the flexible light-transmitting film 42 to be attached to the rigid light-transmitting plate 41 to form an information identification mark.

[0113] When the vehicle 4 is moved by the information editing channel 5 and sent into the x-test channel 14, the light 62 emitted by the light source 6 of the corresponding x-test channel 14 can pass through the rigid light-transmitting plate 41 and the flexible light-transmitting film 42 and irradiate the photosensor 61. At this time, due to the gap between the flexible light-transmitting film 42 and the rigid light-transmitting plate 41, the flexible light-transmitting film 42 and the rigid light-transmitting plate 41 disperse the light 62, and the part where the flexible light-transmitting film 42 is attached to the rigid light-transmitting plate 41 can directly irradiate the light 62, so that the developed image 44 on the rigid light-transmitting plate 41 irradiates the photosensor 61. The photosensor 61 obtains and registers the product information in the vehicle 4 through the images 44 distributed at different positions, areas and shapes (the image 44 is the information identification mark, and the information identification mark can be a symbol with a specific shape and size), and at the same time enters the stroke information corresponding to the rotation of the x-test channel 14 into the corresponding product.
