Description

Technical Field

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

[0002] An inertial measurement unit is a device used to measure an object's three-axis attitude angle (or angular rate) and acceleration. It usually combines an accelerometer and a gyroscope, and sometimes a magnetometer, to comprehensively measure and report an object's specific force, angular velocity, and surrounding magnetic field. With the development of technology and society's pursuit of the functionality of mobile devices, today's small consumer electronic products (such as mobile phones, tablets, and VR devices) are generally equipped with inertial measurement units. In electronic product manufacturers, in order to ensure the performance, quality and reliability of electronic products before leaving the factory, manufacturers generally test electronic products, and the inertial measurement unit in electronic products is no exception. In conventional inertial measurement unit testing devices, electronic products are generally loaded from the conveyor line to the test station through a loading mechanism, and the test station pushes the product to move in a straight line, thereby testing the inertial measurement unit of the electronic product, and finally the unloading mechanism unloads the tested electronic product to the conveyor line; therefore, there are the following technical problems: 1. Since electronic products need 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 is required, the preparation cost of the production line is high and the space occupied is large; 3. Since conventional testing equipment generally simply pushes the product to move in a straight line, it is difficult to fully reflect the performance of the inertial measurement unit during the test. Summary of the invention

[0003] The purpose of the present invention is to provide an inertial measurement unit testing device to solve the technical defects described in the background technology.

[0004] 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.

[0005] Based on the above technical solution, the present invention achieves the following beneficial effects: 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; 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; 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.

[0006] 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.

[0007] 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.

[0008] Based on the above technical solution, the present invention further achieves the following beneficial effects: 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; 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; 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.

[0009] 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 y interception shaft is fixed with a y interception block extending outward. The y interception motor is used to drive the y interception shaft to drive the y interception block to swing into the lower end of the y test channel to limit the product from sliding out of the bottom exit of the y test channel. The y-axis motor is used to drive the y-axis shaft to drive the y-axis rotating frame to rotate and swing longitudinally at a preset angle and speed, so that the product in the y test channel rotates and swings longitudinally at a preset angle and speed. The bottom exit of the y test channel is used to connect with another test platform, test equipment, processing station or conveyor line or channel of the original production line; Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. After the product in the x-connecting flow channel slides in from the top entrance of the y-test channel, the y-interception motor is used to drive the y-interception shaft to drive the y-interception block to swing into the lower end of the y-test channel to limit the product from sliding out from the bottom outlet of the y-test channel. At this time, another project test of the inertial measurement unit of the product can be started. After completing the test of this project, the y-interception motor is used to drive the y-interception shaft to drive the y-interception block to move away from the lower end of the y-test channel. At this time, the product can flow from the bottom outlet of the y-test channel to another test platform, test equipment, processing station or conveyor line or channel of the original production line. Therefore, it is possible to deliver the product in and out of this test platform for another project test without setting up a loading and unloading mechanism, thereby reducing the preparation cost and occupied space of the equipment; 2. When the product slides into the y test channel for testing, the y-axis motor is used to drive the y-axis to drive the y-axis rotating frame to rotate and swing longitudinally at a preset angle and speed, so that the product in the y test channel rotates and swings longitudinally at a preset angle and speed, thereby further adding a longitudinal rotation and swinging motion state to the inertial measurement unit for testing, thereby relatively more comprehensively inspecting the inertial measurement unit.

[0011] 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; Based on the above technical solution, the present invention further achieves the following beneficial effects: 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; 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; 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.

[0012] 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; 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.

[0013] In some embodiments, an inertial measurement unit test device further includes a climbing platform, the climbing platform is equipped with a climbing conveyor line, the inlet end of the climbing conveyor line is horizontally arranged and spliced ​​with the outlet at the bottom end of the y connecting flow channel, the rear half of the climbing conveyor line is tilted upward, and the outlet of the climbing conveyor line is located at the top, so that after the product enters the climbing conveyor line from the y connecting flow channel, the climbing conveyor line drives the product to rise back to the height of entering the x test channel, the outlet of the climbing conveyor line is spliced ​​with a smooth bar, guide blocks are arranged on both sides of the smooth bar, the guide blocks are located at the outlet of the climbing conveyor line, and a discharge blocking mechanism is arranged at the end of the smooth bar, and the end of the smooth bar is used to connect with another test platform, test equipment, processing station or conveyor line or channel of the original production line; Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. Since the x test channel, y test channel, x connection channel and y connection channel are all arranged to be inclined downward, when the product flows out from the y connection channel, the height of the product is lower than the height before it flows into the x test channel from the production line conveyor line. At this time, the product flowing out of the y connection channel can flow into the horizontal part of the climbing conveyor line, so that the climbing conveyor line transfers the product to the upward inclined rear half of the climbing conveyor line. At this time, the rear half of the climbing conveyor line drives the product to rise until the product returns to the height before it flows into the x test channel, so as to facilitate the conveying of the product to another test equipment, processing station or the conveyor line or channel of the original production line; 2. After the product returns to the height before flowing into the x test channel through the climbing conveyor line, the product flows into the smooth strip from the outlet of the climbing conveyor line. At this time, the discharge blocking mechanism intermittently blocks the product in the smooth strip from being pushed out, thereby controlling the frequency of the product flowing into another test platform, test equipment, processing station or conveyor line or channel of the original production line.

[0014] In some embodiments, an inertial measurement unit testing device further includes a carrier for holding and fixing a product, the carrier is provided with a hard light-transmitting plate, a soft light-transmitting film is provided above the hard light-transmitting plate, a gap is provided between the hard light-transmitting plate and the soft light-transmitting film, the soft light-transmitting film is provided with a coating for bonding a certain point position or a plurality of points to the hard light-transmitting plate through static electricity, friction or tension, an x-axis rotating frame is provided with a light source and a photoreceptor, and an x-test channel is located between the light source and the photoreceptor, so that the carrier is located at the x-test channel. When testing the channel, the light emitted by the light source can pass through the hard light-transmitting plate and the soft light-transmitting film to illuminate the photoreceptor. When the light passes through the hard light-transmitting plate and the soft light-transmitting film, due to the gap between the soft light-transmitting film and the hard light-transmitting plate, the soft light-transmitting film and the hard light-transmitting plate scatter the light, while the joint part of the soft light-transmitting film and the hard light-transmitting plate can directly irradiate the light, so that the image developed by the hard light-transmitting plate is irradiated to the photoreceptor. The photoreceptor registers or obtains the product information in the carrier through the images distributed in different positions or quantities; Based on the above technical solution, the present invention further achieves the following beneficial effects: 1. Since there is a gap between the hard light-transmitting plate and the soft light-transmitting film, and at the same time, a certain point or several points of the soft light-transmitting film are bonded to the hard light-transmitting plate, when the light emitted by the light source can pass through the hard light-transmitting plate and the soft light-transmitting film to irradiate the photoreceptor, the gap between the soft light-transmitting film and the hard light-transmitting plate causes the soft light-transmitting film and the hard light-transmitting plate to scatter the light, while the bonding part of the soft light-transmitting film and the hard light-transmitting plate can directly irradiate the light, so that the image developed by the hard light-transmitting plate is irradiated to the photoreceptor. At this time, different positions and different areas of the soft light-transmitting film can be bonded to the hard light-transmitting plate on different carriers, so that the hard light-transmitting plate develops images of different positions and areas. At this time, the photoreceptor obtains and registers the product information in the carrier through the images distributed at different positions and areas; 2. Since carriers are generally recycled, when the carrier is replaced to store another product, the soft light-transmitting film is bonded to the hard light-transmitting board by static electricity, friction or tension through coating, so the bonded part of the soft light-transmitting film and the hard light-transmitting board can be separated. At this time, the position and area of ​​the soft light-transmitting film bonding to the hard light-transmitting board can be changed according to another product, thereby resetting the information identification mark of the carrier; 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.

[0015] 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. 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.

[0016] 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; Based on the above technical solution, the present invention achieves the following beneficial effects: 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; 2. When the slide bar moves to the other end of the slide slot, the bar slides up to the upper sliding slope and rises over the push rod, so that the spring pulls the slide bar back to one end of the slide slot, thereby achieving reset.

[0020] In order to make the objectives, technical solutions and advantages of the present invention more clear, this specific implementation method further describes the present invention in detail with reference to the accompanying drawings.

[0021] like Figures 1 to 8 As shown, this specific embodiment provides an inertial measurement unit testing device, which includes an x-axis test platform 1, on which an x-axis motor 11 is installed, and the x-axis motor 11 is transmission-connected to a longitudinally arranged x-axis 12, on which an x-axis rotating frame 13 arranged to be tilted downward is fixed, and the x-axis rotating frame 13 is provided with a plurality of x-test channels 14 arranged to be tilted downward, and an entrance at the top of the x-test channel 14 is connected to a production line so that the production line can send products placed therein into the x-test channel 14, and an x-interception motor 15 is installed on the x-axis rotating frame 13, and the x-interception motor 15 is transmission-connected to the x-interception rotating frame 13. Shaft 16, an x ​​interception block 161 extending outward is fixed on the x interception shaft 16, the x interception motor 15 is used 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 of the bottom end outlet of the x test channel 14, 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 horizontally 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, and the bottom end outlet of the x test channel 14 is used to connect with another test platform, test equipment, processing station or conveyor line or channel of the original production line.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

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.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] In some embodiments, an inertial measurement unit testing device also includes a y-axis testing platform 2, on which a y-axis motor 21 is installed, and the y-axis motor 21 is transmission-connected to a transversely arranged y-rotating shaft 22, on which a y-axis rotating frame 23 arranged to be tilted downward is fixed, and the y-axis rotating frame 23 is provided with a plurality of y-testing channels 24 arranged to be tilted downward, and the downward tilt angle of the y-testing channel 24 in the initial stage is the same as the downward tilt angle of the x-connecting flow channel 19, and the top entrance position of the y-testing channel 24 is spliced ​​with the bottom outlet of the x-connecting flow channel 19, so that the product in the x-connecting flow channel 19 can slide into the y-testing channel 24, and a y-blocking The y-intercepting motor 25 is connected to the y-intercepting shaft 26 in a transmission manner. The y-intercepting shaft 26 is fixed with a y-intercepting block 261 extending outward. The y-intercepting motor 25 is used to drive the y-intercepting shaft 26 to drive the y-intercepting block 261 to swing into the lower end of the y-testing channel 24 to limit the product from sliding out of the bottom outlet of the y-testing channel 24. The y-axis motor 21 is used to drive 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-testing channel 24 rotates and swings longitudinally at a preset angle and speed. The bottom outlet of the y-testing channel 24 is used to connect with another test platform, test equipment, processing station or conveyor line or channel of the original production line. After the product in the x-connecting flow channel 19 slides into the top entrance position of the y-test channel 24, the y-intercepting motor 25 is used to drive the y-intercepting shaft 26 to drive the y-intercepting block 261 to swing into the lower end of the y-test channel 24 to limit the product from sliding out from the bottom outlet of the y-test channel 24. At this time, another project test of the inertial measurement unit of the product can be started. After completing the project test, the y-intercepting motor 25 is used to drive the y-intercepting shaft 26 to drive the y-intercepting block 261 to move away from the lower end of the y-test channel 24. At this time, the product can flow from the bottom outlet of the y-test channel 24 to another test platform, test equipment, processing station or the conveyor line or channel of the original production line. Therefore, it is possible to deliver the product in and out of the test platform for another project test without setting up a loading and unloading mechanism, thereby reducing the equipment preparation cost and occupied space.

[0031] When the product slides into the y test channel 24 for testing, the y-axis motor 21 is used to drive the y shaft 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 rotates and swings longitudinally at a preset angle and speed, thereby further adding a longitudinal rotation and swinging motion state to the inertial measurement unit for testing, thereby relatively more comprehensively inspecting the inertial measurement unit.

[0032] In some embodiments, a y clamping motor 27 is further installed on the y-axis rotating frame 23, and the y clamping motor 27 is transmission-connected to a y clamping shaft 28, and a y clamping block 281 extends outward from 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 to enter the upper end 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; 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 to enter the upper end of the y test channel 24 and approach the y interception block 261, so as to clamp and fix the product in the y test channel 24, so that the y axis motor 21 is used to drive the y rotating shaft 22 to drive the y axis rotating frame 23 to rotate and swing longitudinally at a larger angle and faster speed, so as to test the inertial measurement unit of the product when the product rotates and swings longitudinally or rotates at a larger angle and faster speed. When the product in the y test channel 24 drives the product in it to rotate and swing longitudinally, it can effectively avoid the displacement of the product, thereby improving the test accuracy; in addition, when the product in the y test channel 24 drives the product in it to rotate and swing longitudinally at a larger amplitude and speed, it can effectively avoid the product from leaving the y test channel 24.

[0033] In some embodiments, a y-connecting channel 29 is also installed on the y-axis test platform 2. The y-connecting channel 29 is tilted downward and fixedly arranged. The downward tilt angle of the y-connecting channel 29 is the same as the downward tilt angle of the y-test channel 24 in the initial stage. The top inlet of the y-connecting 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 delivered to the conveying line or channel connection of another platform, equipment or workstation through the y-connecting channel 29 at a specific downward inclination.

[0034] After the y test channel 24 drives the product therein to rotate and swing horizontally, 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 product is adjusted to a specific downward inclination through the y connecting channel 29, 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.

[0035] In some embodiments, an inertial measurement unit testing device also includes a climbing platform 3, which 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 flow channel 29. The rear half of the climbing conveyor line 31 is tilted upward, and the outlet of the climbing conveyor line 31 is located at the top, so that after the product enters the climbing conveyor line 31 from the y connecting flow channel 29, the climbing conveyor line 31 drives the product to rise back to the height of entering the x test channel 14. The outlet of the climbing conveyor line 31 is spliced ​​with a smooth bar 32, and guide blocks are arranged on both sides of the smooth bar 32. The guide blocks are located at the outlet of the climbing conveyor line 31. A discharge blocking mechanism 33 is arranged at the end of the smooth bar 32. The discharge blocking mechanism 33 can be a cylinder-driven blocking block moved to the end of the smooth bar 32 to achieve blocking. The end of the smooth bar 32 is used to connect with a conveyor line or channel of another test platform, test equipment, processing station or original production line.

[0036] Since the x test channel 14, the y test channel 24, the x connection channel 19 and the y connection channel 29 are all arranged to be inclined downward, when the product flows out from the y connection channel 29, the height of the product is lower than the height before it flows into the x test channel 14 from the production line conveyor line. At this time, the product flowing out of the y connection channel 29 can flow into the horizontal part of the climbing conveyor line 31, so that the climbing conveyor line 31 transfers the product to the upwardly inclined rear half of the climbing conveyor line 31. At this time, the rear half of the climbing conveyor line 31 drives the product to rise until the product returns to the height before it flows into the x test channel 14, so as to facilitate the conveying of the product to another test equipment, processing station or conveyor line or channel of the original production line; After the product returns to the height before flowing into the x test channel 14 through the climbing conveyor line 31, the product flows into the smooth strip 32 from the outlet of the climbing conveyor line 31. At this time, the discharge blocking mechanism 33 intermittently blocks the product in the smooth strip 32 from being pushed out, thereby controlling the frequency of the product flowing into another test platform, test equipment, processing station or conveyor line or channel of the original production line.

[0037] In some embodiments, an inertial measurement unit testing device further includes a carrier 4 for holding and fixing a product, the carrier 4 is provided with a hard light-transmitting plate 41, a soft light-transmitting film 42 is provided above the hard light-transmitting plate 41, a gap is provided between the hard light-transmitting plate 41 and the soft light-transmitting film 42, the soft light-transmitting film 42 is provided with a coating 43 for bonding a certain point position or several points to the hard light-transmitting plate 41 through static electricity, friction or tension, an x-axis rotating frame 13 is provided with a light source 6 and a photoreceptor 61, and an x-test channel 14 is located between the light source 6 and the photoreceptor 61, so that when the carrier 4 is located in the x-test channel 14, the light The light 62 emitted by the source 6 can pass through the hard light-transmitting plate 41 and the soft light-transmitting film 42 to illuminate the photoreceptor 61. When the light 62 passes through the hard light-transmitting plate 41 and the soft light-transmitting film 42, due to the gap between the soft light-transmitting film 42 and the hard light-transmitting plate 41, the soft light-transmitting film 42 and the hard light-transmitting plate 41 scatter the light 62, while the part where the soft light-transmitting film 42 and the hard light-transmitting plate 41 are bonded can directly irradiate the light 62, so that the image 44 developed by the hard light-transmitting plate 41 is illuminated to the photoreceptor 61. The photoreceptor 61 registers or obtains the product information in the carrier 4 through the images 44 distributed in different positions or quantities.

[0038] Since there is a gap between the hard light-transmitting plate 41 and the soft light-transmitting film 42, and at the same time, a certain point or several points of the soft light-transmitting film 42 are bonded to the hard light-transmitting plate 41, when the light 62 emitted by the light source 6 can pass through the hard light-transmitting plate 41 and the soft light-transmitting film 42 to irradiate the photoreceptor 61, the soft light-transmitting film 42 and the hard light-transmitting plate 41 scatter the light 62, and the soft light-transmitting film 42 and the hard light-transmitting plate 41 are scattered. The part attached to the hard light-transmitting plate 41 can directly irradiate the light 62, so that the image 44 developed by the hard light-transmitting plate 41 is irradiated to the photoreceptor 61. At this time, the soft light-transmitting film 42 can be bonded to the hard light-transmitting plate 41 at different positions and different areas on different carriers 4, so that the hard light-transmitting plate 41 develops images 44 at different positions and areas. At this time, the photoreceptor 61 obtains and registers the product information in the carrier 4 through the images 44 distributed at different positions and areas.

[0039] Since the carrier 4 is generally recycled, when the carrier 4 is replaced to store another product, since the soft light-transmitting film 42 is bonded to the hard light-transmitting plate 41 by electrostatic force, friction force or tension through the coating 43, the bonded portion of the soft light-transmitting film 42 and the hard light-transmitting plate 41 can be separated. At this time, the position and area where the soft light-transmitting film 42 is bonded to the hard light-transmitting plate 41 can be changed according to another product, thereby resetting the information identification mark of the carrier 4; Since the x-axis rotating frame 13 rotates around the x-axis 12, that is, the rotation stroke of each x-test channel 14 on the x-axis rotating frame 13 is different, the lateral rotation and swinging motion strokes between the products in each x-test channel 14 are also different, that is, the values ​​measured by the inertial measurement unit in each x-test channel 14 are also different. 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.

[0040] In some embodiments, an information editing channel 5 is independently arranged 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 and passes through the information editing channel 5 in advance and stays in the information editing channel 5. Each information editing channel 5 is provided with a downward pressing power module 51. Each downward pressing power module 51 drives a pressure block 52 for pressing down on the soft light-transmitting film 42. The pressure block 52 is distributed with a plurality of pressure points 53 that push a certain point of the soft light-transmitting film 42 to fit with the hard light-transmitting plate 41. The distribution position and area of ​​the pressure points 53 on any pressure block 52 are different from those of the pressure points 53 of the remaining pressure blocks 52.

[0041] 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 pressure power module 51 in the information editing channel 5 drives the pressure block 52 to press down onto the soft light-transmitting film 42, and the pressure point 53 of the pressure block 52 pushes a certain point of the soft light-transmitting film 42 to fit with the hard light-transmitting plate 41, thereby realizing the editing of the information identification mark of the carrier 4 into the x test channel 14 that it is about to enter.

[0042] In some embodiments, the carrier 4 is provided with a slide groove 45, in which a slide rod 46 is slidable between the hard light-transmitting plate 41 and the soft light-transmitting film 42, and the slide groove 45 is provided with a spring 48 for pulling the slide rod 46 to one end, and the information editing channel 5 is fixedly provided with a push rod 54 located 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 slide rod 46 to move to the other end of the slide groove 45, so that the slide rod 46 separates the part where the soft light-transmitting film 42 and the hard light-transmitting plate 41 are attached, and an upper sliding slope 47 is provided at the other end of the slide groove 45, so that when the slide rod 46 is pushed to the other end of the slide groove 45 by the push rod 54, the slide rod 46 slides up to the upper sliding slope 47 and rises over the push rod 54. At this time, the spring 48 pulls the slide rod 46 to reset.

[0043] Before the pressing power module 51 in the information editing channel 5 is used to drive the pressure block 52 to press down onto the soft light-transmitting film 42, in the process of moving the carrier 4 to the position of the pressing power module 51 through the information editing channel 5, the fixed push rod 54 is used to push the slide bar 46 to move to the other end of the slide groove 45, so that the slide bar 46 separates the part where the soft light-transmitting film 42 and the hard light-transmitting plate 41 are in contact, thereby automatically resetting the information identification mark of the carrier 4; when the slide bar 46 moves to the other end of the slide groove 45, the rod slides up to the upper sliding slope 47 and rises over the push rod 54, so that the spring 48 pulls the slide bar 46 back to one end of the slide groove 45, thereby achieving resetting.

[0044] In order to further illustrate the inertial measurement unit testing device described in this specific implementation manner, the following embodiments are listed. Example

[0048] The x-axis rotating frame 13 is provided with an x-intercepting motor 15 and an x-clamping motor 17. The x-intercepting motor 15 is connected to the x-intercepting rotating shaft 16, and an x-intercepting block 161 extending outward is fixed on the x-intercepting rotating shaft 16. The x-intercepting motor 15 drives the x-intercepting rotating shaft 16 to drive the x-intercepting block 161 to swing into the lower end of the x-testing channel 14 to limit the product from sliding out of the bottom exit of the x-testing channel 14.

[0058] The following is a working description of an inertial measurement unit testing device described in this embodiment.

[0059] As the product on the production line slides in from the entrance at the top of the x test channel 14, the inertial measurement unit of the product is tested in a linear motion state.

[0060] 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.

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.

[0061] 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.

When the light 62 passes through the hard light-transmitting plate 41 and the soft light-transmitting film 42, due to the gap between the soft light-transmitting film 42 and the hard light-transmitting plate 41, the soft light-transmitting film 42 and the hard light-transmitting plate 41 scatter the light 62, while the bonding portion between the soft light-transmitting film 42 and the hard light-transmitting plate 41 can directly irradiate the light 62, so that the image 44 developed by the hard light-transmitting plate 41 is irradiated onto the photoreceptor 61.

[0065] An information editing channel 5 is independently arranged in front of the entrance of each x test channel 14, so that the carrier 4 with the product placed on it enters the x test channel 14 and passes through the information editing channel 5 in advance and stays in the information editing channel 5. Each information editing channel 5 is provided with a pressing power module 51. Each 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 plurality of pressure points 53 that push a certain point of the soft light-transmitting film 42 to fit with the hard light-transmitting plate 41. The distribution position and area of ​​the pressure points 53 on any one of the pressing blocks 52 are different from those of the pressure points 53 of the remaining pressing blocks 52.

[0066] The carrier 4 is provided with a slide groove 45, in which a slide bar 46 is slidable between the hard light-transmitting plate 41 and the soft light-transmitting film 42. The slide groove 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 located 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 slide bar 46 to move to the other end of the slide groove 45, so that the slide bar 46 separates the part where the soft light-transmitting film 42 and the hard light-transmitting plate 41 are attached. An upper sliding slope 47 is provided at the other end of the slide groove 45, so that when the slide bar 46 is pushed to the other end of the slide groove 45 by the push rod 54, the slide bar 46 slides up to the upper sliding slope 47 and rises over the push rod 54. At this time, the spring 48 pulls the slide bar 46 to reset.

[0067] The following is a working process of an inertial measurement unit testing device described in this embodiment.

[0068] Before the carrier 4 supporting the product enters the x-test channel 14, it passes through the information editing channel 5 in advance. During the process of moving the carrier 4 through the information editing channel 5, the fixed push rod 54 is used to push the slide bar 46 from the left end of the slide groove 45 to the right end, so that the slide bar 46 separates the part where the soft light-transmitting film 42 and the hard light-transmitting plate 41 are attached, thereby automatically resetting the information identification mark of the carrier 4; when the slide bar 46 moves to the right end of the slide groove 45, the rod slides up to the upper slide slope 4 7 rises and passes over the push rod 54, and the spring 48 pulls the slide bar 46 to return to the left end of the slide slot 45, thereby resetting; thereafter, the information editing channel 5 moves the carrier 4 to the position corresponding to the pressing power module 51. At this time, the information editing channel 5 pauses moving the carrier 4, and the pressing power module 51 drives the pressing block 52 to press down on the soft light-transmitting film 42. The pressure point 53 of the pressing block 52 pushes a certain position of the soft light-transmitting film 42 to fit with the hard light-transmitting plate 41 to form an information identification mark.

[0069] When the carrier 4 is moved and sent to the x test channel 14 by the information editing channel 5, the light 62 emitted by the light source 6 of the corresponding x test channel 14 can pass through the hard light-transmitting plate 41 and the soft light-transmitting film 42 to irradiate the photoreceptor 61. At this time, there is a gap between the soft light-transmitting film 42 and the hard light-transmitting plate 41, so that the soft light-transmitting film 42 and the hard light-transmitting plate 41 scatter the light 62, and the bonding part between the soft light-transmitting film 42 and the hard light-transmitting plate 41 can directly irradiate the light 62, so that the image 44 developed by the hard light-transmitting plate 41 is irradiated to the photoreceptor 61. The photoreceptor 61 obtains and registers the product information in the carrier 4 through the images 44 distributed in different positions, areas and shapes (the image 44 is the information identification mark, which can be a symbol of a specific shape and size), and at the same time, the stroke information of the rotation of the corresponding x test channel 14 is recorded into the corresponding product.
