As shown in fig. 1, the swing testing system provided by the application is used for testing the swing of a tested piece, and the tested piece is provided with a swinging part capable of swinging. The swing test system includes a control module 10, a light source 20, and a vision module 30.
The light source 20 is used for emitting light beams to a light reflecting module arranged on the swinging part of the tested piece. The light beam can be parallel light, namely, each light ray is basically parallel, and the light beam can be better used for detecting swing amplitude. In this embodiment, the light source 20 is a laser module, such as a laser, and the corresponding light beam is a laser. The laser beam is not only straight but also high in brightness, so that the subsequent clear imaging is facilitated. The light source 20 may be manually controlled to be turned on or off, or may be controlled by the control module 10, and the latter is exemplified in this embodiment. The light source 20 is connected to the control module 10, and is configured to receive a start instruction of the control module 10 and emit a light beam. The light source 20 may be directed at the reflector module in advance so as to direct a light beam toward the reflector module. The reflecting module can reflect laser and is arranged on the swinging part of the tested piece in advance. The light reflecting module can be a light reflecting film and the like and can be conveniently attached to the swinging part.
The vision module 30 is configured to collect one or more images of the light beam reflected by the light reflecting module, and transmit the collected images to the control module 10. The vision module 30 may employ an image acquisition module such as a camera, a video camera, or the like.
The control module 10 realizes the swing amplitude test of the swing part of the tested piece by controlling other functional modules of the swing amplitude test system. It may be various devices having arithmetic processing capability, such as a CPU, a single chip microcomputer, MCU, FPGA, PLC, a PCB board capable of realizing the functions of the control module 10 described below, and the like. The specific process of the swing test system for performing the swing test is shown in fig. 2, and comprises the following steps:
step 1, the control module 10 obtains the test parameters of the tested piece. The test parameter may be an operating parameter of the test piece. The test parameters may be pre-stored in a memory of the swing test system from which the control module 10 retrieves the test parameters. The control module 10 may also obtain test parameters from an external device. The test parameters may also be entered by the user.
And 2, the control module 10 generates a control instruction according to the test parameters, wherein the control instruction is used for controlling the tested piece to work based on the test parameters.
And 3, controlling the light source 20 to emit light beams to the light reflecting module arranged on the swinging part of the tested piece. The step may be performed manually, or may be performed by the control module 10, and in this embodiment, the control module 10 controls the light source 20 to emit a light beam to a light reflecting module disposed on the swinging portion of the measured piece. The light source 20 may be disposed near the swinging portion of the tested piece, for example, the tested piece is an electric toothbrush, and the light source 20 may be disposed near the brush head of the tested electric toothbrush, specifically, may be disposed obliquely above the light reflecting module according to the position of the light reflecting module. The control module 10 instructs the control unit to start the electric toothbrush by the instruction and at the same time starts the laser module, so that the laser module projects a laser spot to the light reflecting module. The reflecting module can be, for example, a light-weight resin lens or the like, and is attached to the back of the brush rod or the back of the brush head in advance by a tester, and when the tested electric toothbrush swings, laser reflected by the reflecting module can form a light beam on the receiving module, and the length of the light beam is the amplified swing.
And 4, the control module 10 collects one or more frames of images of the light beam reflected by the light reflecting module through the vision module 30.
And 5, the control module 10 obtains the swing characteristic quantity of the tested piece corresponding to the test parameter according to one or more frames of images acquired by the vision module 30. The swinging part of the measured piece swings reciprocally, the light reflecting module on the swinging part also swings along with the swinging, and then the light spot of the light beam reflected by the light reflecting module also swings, so that the image collected by the vision module 30 can reflect the swinging. The control module 10 processes the image to obtain the swing characterization quantity reflecting the swing. The process is basically automatically completed by the swing test system, so that the labor is greatly saved, and the accuracy is higher than that of manual measurement.
The tested piece can be various components capable of swinging, such as an acoustic motor, an electric toothbrush and the like. The swing test system and the swing test method thereof will be described in detail below using an electric toothbrush as an example. As shown in fig. 1 and 3, the swing test system also includes a control component 40 and a load module 50. The process of swing testing the electric toothbrush by the swing testing system is shown in fig. 4, and comprises the following steps:
step 1', the control module 10 obtains the test parameters of the tested electric toothbrush, wherein the test parameters comprise a working mode and/or a gear. The electric toothbrush has at least one mode of operation, and typically has a plurality of modes of operation, such as one or more of a cleaning mode, a whitening mode, a massaging mode, and a soft mode. Different modes of operation typically have different swings (swing amplitudes). Each mode of operation may also have different gears, which typically have different frequencies of oscillation. The control module 10 may directly obtain the test parameters of the tested electric toothbrush, such as from a memory, an external device, or by user input; the model of the tested electric toothbrush can also be obtained, for example, the model of the tested electric toothbrush is obtained from a memory and an external device or the model of the tested electric toothbrush is input by a user, and then the test parameters corresponding to the model in advance are obtained according to the model. The control module 10 may also obtain the load parameter of the tested electric toothbrush, and similarly, may directly obtain the load parameter of the tested electric toothbrush, or may obtain the model of the tested electric toothbrush, so as to obtain the load parameter corresponding to the model in advance according to the model.
The swing testing system may further include a man-machine interaction device 80, where the man-machine interaction device 80 is used for man-machine interaction, such as input devices including various keys, a keyboard, a mouse, and/or a touch screen, and output devices including an indicator light, a speaker, and/or various displays. The control module 10 may receive one or more of test parameters, model numbers, and load parameters of the tested electric toothbrush, etc., inputted by a user through the human-computer interaction device. I.e. test parameters, model and load parameters etc. may be manually entered by the user.
The swing test system may further include a communication module, which may be wired, such as a communication interface, to an external terminal, and may also be wireless, such as a bluetooth module, and the wireless communication module is wirelessly connected to the external terminal. The control module 10 may also receive one or more of test parameters, model numbers, and load parameters of the tested electric toothbrush, etc., sent from the external terminal through the communication module.
And 2', the control module 10 generates a control instruction according to the test parameters, wherein the control instruction is used for controlling the tested electric toothbrush to work based on the corresponding test parameters. The control module 10 can be connected with the tested electric toothbrush, and can directly output a control instruction to the tested electric toothbrush so as to enable the tested electric toothbrush to work in a working mode and/or a gear corresponding to the test parameters. Of course, the control module 10 can also control the tested electric toothbrush through the control part 40, which is described in detail in this embodiment.
The control part 40 is arranged opposite to the key a1 of the tested electric toothbrush. In this embodiment, the tested electric toothbrush is held and fixed by the fixture, and the user aligns the key a1 to the control part 40 (e.g., makes the key a1 located right under the control part 40) when holding the tested electric toothbrush. In another embodiment, the position of the control unit 40 is adjustable, and the user can adjust the position of the control unit 40 to align with the key a1, for example, the control unit 40 is located directly above the key a1 of the tested electric toothbrush. The control unit 40 may replace the user's hand and has a telescopic mechanism which is extended downwardly to press the button a1 of the electric toothbrush under test, thereby controlling its operation mode and/or gear. The control module 10 generates a corresponding control command according to the test parameters and transmits the control command to the control unit 40. The control command is used for instructing the control part 40 to control the button a1 of the tested electric toothbrush so that the tested electric toothbrush works based on the test parameters. For example, the control instructions instruct the control section 40 to operate the keys of the electric toothbrush under test to automatically adjust the operation mode and gear of the electric toothbrush, and to automatically control the start and stop. Therefore, after the tested electric toothbrush is arranged in the system, a user does not need to manually press a toothbrush key, the system automatically controls the toothbrush according to the test parameters, the degree of automation is high, and the test efficiency is improved.
The load module 50 is also used to provide a simulated working environment of the tested electric toothbrush, that is, the load module 50 is used to simulate the working environment of the tested electric toothbrush to provide a load for the electric toothbrush. The swing characteristic quantity measured in this way is more representative and more accurate, and the tooth brushing effect can be better estimated later. The load module 50 is disposed on the brush head a3 side of the electric toothbrush under test.
The control module 10 generates a corresponding load command according to the load parameter and transmits the load command to the load module 50. The load instructions are used to instruct the load module 50 to provide a simulated operating environment for the electric toothbrush under test based on the load parameters.
Referring also to fig. 5, the load module 50 includes a profiling block 51 or tooth die (not shown). The profiling pressing block 51 is a structure matched with the shape of the brush hair of the brush head a3 so as to ensure that each brush hair on the brush head a3 is basically jointed with the profiling pressing block 51, in other words, the surface of the profiling pressing block 51 is matched with the brush hair of the tested electric toothbrush so as to joint the brush hair, thereby improving the accuracy of swing test. The dental model is then a dental model for simulating teeth in the mouth. The profiling pressing block 51 or the tooth mold can be divided into a human body and a child, and users can test toothbrushes with different sizes only by replacing different profiling pressing blocks 51 or tooth molds, so that the toothbrush is very convenient.
The load module 50 further comprises a first drive 52, a nozzle 53, a clamp 54 and a second drive 55.
The first driving means 52 is for driving the dental model or profiling compact 51 to reciprocate to simulate the brushing process. The load parameters may include the speed of movement of the tooth form or profiling compact 51. The first driving means 52 may comprise, for example, a stepper motor. The control module 10 can simulate brushing and the speed of brushing movement (the speed of movement of the die or contoured compact 51) by controlling the reciprocating motion of the stepper motor, as well as the speed of the reciprocating motion.
The nozzle 53 is used to spray mist, water column or toothpaste foam to the brush head a3 of the tested electric toothbrush to simulate a moist environment in the oral cavity. The load parameter may include a flow rate of the liquid ejected by the nozzle 53 and/or a flow rate of the liquid ejected by the nozzle 53. The load module 50 may also include a pump or valve, etc., by which the control module 10 controls the flow and/or rate of liquid ejected from the nozzles 53.
The fixture 54 is used to secure the electric toothbrush under test.
The second driving device 55 is used for driving the clamp 54 to move so as to adjust the pressure of the brush head a3 of the tested electric toothbrush, which is contacted with the tooth mold or profiling pressing block 51. The load parameter may include the pressure. The second driving means 55 may include a lifting mechanism by which the control module 10 controls the height position of the jig 54 to control the pressure at which the brush head a3 contacts the tooth mold or the profiling block 51.
And 3', controlling the light source 20 to emit light beams to the light reflecting module arranged on the swinging part of the tested electric toothbrush. In this embodiment, the control module 10 controls the light source 20 to emit light beams to the light reflecting module arranged on the swinging part of the tested electric toothbrush. In this embodiment, the laser module is connected to the control module 10. The laser module receives the starting instruction of the control module 10 and projects a laser spot to a preset position in the swing test system. The preset position is the back of the brush rod a2 or the back of the brush head a3 after the toothbrush is fixed. The reflecting module can be arranged on the back of the brush rod a2 or the back of the brush head a3, the projected laser points are reflected, and the reflected laser is received when the tested electric toothbrush works, so that corresponding swing detection can be performed. The reflective module is arranged on the back of the a2 or the a3, so that the interference of boiled water, foam and the like can be avoided. In embodiments without the load module 50, the light reflecting module may also be disposed on the front of the brush bar a2 or the brush head a 3.
In step 4', the control module 10 collects one or more images of the light beam reflected by the light reflection module 60 through the vision module 30. The vision module 30 may directly collect images against the light reflecting module 60, or a receiving module 70 may be disposed on the light path of the light beam reflected by the light reflecting module 60. The latter example is described as an example. The vision module 30 may be disposed below the receiving module 70. The optical path of the light beam is shown by the dotted arrow in fig. 3, and thus the light beam reflected by the reflection module 60 forms a light beam b on the reception module 70 when the swing portion swings. The length of the beam b has a functional relation with the swing. The distance between the receiving module 70 and the reflecting module 60 is greater than the distance between the light source 20 and the reflecting module 60, so that the length of the light beam b is greater than the swing amplitude, which is equivalent to the amplified swing amplitude (the swing amplitude is usually very small), and the measurement error can be reduced. The heights of the receiving module 70, the reflecting module 60 and the light source 20 are known, and the angle of incidence of the light beam on the reflecting module 60 is known, so that the swing can be calculated according to the length of the light beam b. The receiving module 70 may be a semi-transparent acrylic plate, which can present the light beam b. In this embodiment, the light beam emitted from the light source 20 is parallel to the plane formed by the swing of the swing portion, so that the vertical light beam b can be well formed.
The vision module 30 captures one or more images of the receiving module 70 in real time and transmits the captured images to the control module 10. The vision module 30 can sample the long exposure, i.e. the exposure is performed with a preset exposure time, so that a line (beam b) formed by the movement of the laser spot can be displayed on one frame of image, and the subsequent control module 10 can know the length of the beam b by identifying the beam b from the image. Of course, a video may be captured to obtain continuous multi-frame images, each frame of image may have only one laser spot, each spot is overlapped to form a light beam b, and the subsequent control module 10 identifies and locates the light spots in the continuous multi-frame images, so that the length of the light beam b can be known.
And step 5', the control module 10 obtains the swing characteristic quantity of the tested electric toothbrush corresponding to the testing parameters according to the one or more frames of images. For example, the control module 10 processes the image (see the previous step specifically) to obtain the length of the beam b, and may use the length of the beam b as the oscillation amplitude characterizing quantity, or calculate the oscillation amplitude according to the length of the beam b, and use the oscillation amplitude as the oscillation amplitude characterizing quantity.
And step 6', the control module 10 judges whether the swing characteristic quantity is qualified or not and outputs a judging result. Specifically, a set of test parameters is preset with a qualified range. The control module 10 obtains a qualified range corresponding to the test parameter in advance according to the test parameter, judges whether the swing characteristic quantity is in the qualified range, if so, determines that the swing corresponding to the test parameter is qualified and outputs a result of qualified swing, otherwise, determines that the swing corresponding to the test parameter is unqualified and outputs a result of unqualified swing. The qualified range is the normal range of the swing of the electric toothbrush under the corresponding test parameters. In this embodiment, a database is preset, and the database stores the types of the plurality of electric toothbrushes and the qualification range of one or more sets of test parameters corresponding to the types. The control module 10 obtains the qualified range corresponding to the test parameter according to the test parameter, including: and matching the corresponding qualified range from a preset database according to the model and the test parameters of the tested electric toothbrush.
As shown in fig. 5, the system can test a plurality of electric toothbrushes at the same time, and only a plurality of sets of light sources 20, a plurality of sets of tooth dies or profiling pressing blocks 51, a plurality of sets of control components 40 and the like are correspondingly arranged, so that the clamp 54, the control module 10, the first driving device 52, the second driving device 55, the vision module 30, the receiving module 70 and the like can be shared, and the testing efficiency is higher.
The swing testing method of the electric toothbrush provides basic testing procedures and ideas, and more specific procedures can be varied, and two kinds of procedures are exemplified below.
In a specific swing test process as shown in fig. 6, in step 1″, the control module 10 may obtain the model number, test parameters and load parameters of the tested electric toothbrush inputted by the tester; further, in step 2″ a control command is generated according to the test parameter to instruct the control unit 40 to adjust the working mode and gear of the tested electric toothbrush, for example, the control module 10 generates a control command according to the test parameter and issues a control command to the control unit 40 to instruct the control unit 40 to operate the button a1 of the tested electric toothbrush, so that the tested electric toothbrush is adjusted to the working mode (brushing mode) and gear corresponding to the test parameter.
Likewise, in step 2", the control module 10 generates a load command based on the load parameter to instruct the load module to provide a simulated operating environment for the electric toothbrush under test based on the load parameter. For example, a load command is generated according to the load parameter and issued to the load module 50 to instruct the load module 50 to provide a simulated working environment of the tested electric toothbrush based on the load parameter, such as instructing the load module 50 to adjust the movement speed of the tooth mold, the brush head pressure, the water flow of the spray head, etc.
In step 3", the control module 10 controls the light source to emit light beam to the light reflecting module arranged on the swinging part of the tested electric toothbrush.
In step 4", the control module 10 collects one or more images of the light beam reflected by the light reflecting module through the vision module. For example, the control module 10 instructs the control button a1 to start the tested electric toothbrush in a mode of transmitting an instruction, and transmits a corresponding instruction to the vision module 30 so as to control the vision module 30 to collect a corresponding reflected light beam image when the tested electric toothbrush swings.
In step 5", the control module 10 obtains the swing characteristic quantity of the tested electric toothbrush corresponding to the test parameter according to the one or more images, for example, obtains the length of the light beam corresponding to the test parameter according to the one or more reflected light beam images.
In step 6", the control module 10 also matches the corresponding qualified range (swing range) from the preset database according to the model number and the test parameters of the tested electric toothbrush. The swing ranges of the test parameters of different types in the database can be recorded in advance by a tester, for example, the swing range of the electric toothbrush of the type A in the 1 st gear in the whitening mode should be within [ a, b ], and the swing of the electric toothbrush to be tested is tested to be qualified if the test swing of the electric toothbrush of the type A in the 1 st gear in the whitening mode is within [ a, b ] during actual measurement, otherwise, the test swing of the electric toothbrush to be tested is not qualified.
The control module 10 judges whether the swing characteristic quantity is in a qualified range and outputs a judging result. For example, after the beam image is obtained and the length of the beam is extracted, the beam length can be used to directly determine whether the swing of the current mode and gear of the tested electric toothbrush is qualified. Specifically, the database can be pre-stored with the corresponding beam length ranges of each mode and gear of each toothbrush model, after the current beam length is extracted, the corresponding beam length ranges can be matched from the database, and whether the current beam length is within the beam length ranges is judged, so that whether the swing of the current mode and gear of the tested electric toothbrush is qualified is obtained.
The test parameters acquired by the control module 10 may be one set, and the process shown in fig. 4/6 is performed once when one set of test parameters is acquired, and then another set of test parameters may be acquired again, and the process shown in fig. 4/6 is performed again until all the test parameters are tested. Multiple (two or more) sets of test parameters may also be acquired at a time. As shown in fig. 7, in step 1' ", the control module 10 acquires the model number, a plurality of test parameters, and a load parameter of the tested electric toothbrush inputted by the tester. The specific process may be the same as step 1' and step 1″ in the above embodiment, and will not be described herein.
In step 2' ", the control module 10 generates control instructions according to the current test parameters to instruct the control component to adjust the operating mode and gear of the electric toothbrush under test, and generates load instructions according to the load parameters to instruct the load module to provide a simulated operating environment of the electric toothbrush under test based on the load parameters. The specific process is the same as the steps 2' and 2″ in the above embodiment, and will not be described herein.
In step 3' ", the control module 10 controls the light source to emit light beam to the light reflecting module arranged on the swinging part of the tested electric toothbrush. The specific process is the same as the steps 3', 3″ of the above embodiment, and will not be described herein.
In step 4' ", the control module 10 collects one or more images of the light beam reflected by the light reflecting module through the vision module. The specific process is the same as step 4' and step 4″ in the above embodiment, and will not be described herein.
In step 5' ", the control module 10 obtains the swing characteristic quantity of the tested electric toothbrush corresponding to the current test parameter according to the one or more frames of images. The specific process is the same as the steps 5' and 5″ in the above embodiment, and will not be described herein.
In step 6' ", the control module 10 further matches a corresponding qualified range from a preset database according to the model number and the current test parameters of the tested electric toothbrush, and determines whether the swing characteristic quantity is in the qualified range. If the swing characteristic quantity is in the qualified range, the step 7', is entered. The specific judging process is the same as the steps 6' and 6″ in the above embodiment, and will not be described herein.
In step 7 '", the control module 10 determines whether all the test parameters are tested, if not, it goes to step 8'", if so, it ends the whole swing test.
In step 8 '", the control module 10 switches to the next test parameter according to the preset sequence, and returns to step 2'". I.e. after one set of test parameters is tested (the result of whether the test parameters are in a qualified range is obtained) the next set of test parameters is tested.
In other words, the control module 10 generates a set of control instructions based on a set of test parameters according to a preset sequence, after obtaining the swing characteristic quantity corresponding to the set of test parameters, that is, after executing the step 2 '"-6'" once, generates a set of control instructions based on the next set of test parameters, and executes the step 2 '"-6'" again until each set of test parameters obtains the corresponding swing characteristic quantity and whether the corresponding swing characteristic quantity is qualified or not. The preset sequence can be random, or the sequence of inputting the test parameters can be the same; a set of control instructions is used to instruct the control unit 40 to control the keys of the electric toothbrush under test so that the electric toothbrush under test operates based on a corresponding set of test parameters.
After the swing amplitude corresponding to all the test parameters of the tested electric toothbrush is judged (namely, whether the electric toothbrush is qualified or not) is judged, the test of the current tested electric toothbrush can be finished, and then the next electric toothbrush is tested.
Through the electric toothbrush swing test system, a user only needs to set the tested electric toothbrush in the system, then the swing test of the tested electric toothbrush can be automatically completed in a command input mode, and whether the swing is qualified or not is output, so that the efficiency of swing test is improved, and errors caused by manual measurement are avoided.
