Description

Technical Field

[0001] This application belongs to the technical field of distance sensor testing, and specifically relates to a detection device. Background Art

[0002] The traditional method for detecting a distance sensor is as follows: The staff connects the distance sensor to the detection circuit and turns on the power supply, making the light-emitting side of the distance sensor emit light. The light is reflected by means of a reflective paper, and the light-receiving side outputs a voltage signal according to the intensity of the emitted light, so as to determine whether the distance sensor is qualified.

[0032] It can be understood that in the present application, by disposing the connector 2 on the stage 11 in a liftable manner, it can better adapt to devices under test of different sizes and specifications, ensure stable electrical connection, and reduce detection errors and unstable factors caused by poor contact; at the same time, by providing the driving assembly 3, and driving the reflecting sheet 4 to switch between different positions through the cam 32 and the first swing arm 321 thereon of the driving assembly 3, automatic detection can be realized, manual intervention can be reduced, the detection process can be accelerated, and the overall detection efficiency can be improved.

[0033] Among them, the device under test may be a distance sensor, a laser ranging sensor, an infrared ranging sensor, an optical encoder, a time-of-flight sensor, etc.

[0034] Specifically, in this embodiment, the device under test is a distance sensor, and the detection device is used to detect the electrical characteristics of the distance sensor.

[0035] Among them, the detection device includes a detection box 1. The detection box 1 is generally a rectangular box body. The top of the detection box 1 has a stage 11 for carrying the device under test, providing a stable support platform for the device under test, ensuring that the device under test will not move or shake during the detection process, and guaranteeing the repeatability and consistency of the detection.

[0036] Specifically, an opening 111 is provided at the position on the stage 11 corresponding to the device under test, which can achieve specific detection functions, such as the precise incidence of light or the transmission of other detection signals. It should be noted that when the device under test is a distance sensor, the opening 111 is used for the light emitted by the distance sensor when powered on and the reflected light to pass through, so as to reduce interference and improve the accuracy and precision of the detection.

[0037] Among them, a connector 2 is provided on the stage 11, and the connector 2 and the device under test are located on the same side of the stage 11.

[0038] Specifically, the connector 2 can be a PIN pin. The PIN pin is arranged on the stage 11 in a liftable manner. The PIN pin is used for electrical connection with the device under test, realizing the conduction of the circuit inside the device under test and the external circuit, specifically conducting with the detection circuit, so as to detect the electrical characteristics of the device under test.

[0039] Among them, the connector 2 can be arranged on the stage 11 in a liftable manner through any one of a motor and a lead screw assembly, a cylinder and a guide rod assembly, a linear guide rail and a slider assembly, a cam 32 and a push rod assembly, an electromagnet and an armature assembly, and a worm gear and a rack assembly.

[0040] Specifically, the connector 2 and the device under test are arranged opposite to each other in the vertical direction on the stage 11, so that when the connector 2 moves close to the device under test, it can contact the device under test, realizing connecting the device under test into the detection circuit and turning on the power supply. It should be noted that when the device under test is a distance sensor, the distance sensor includes a light-emitting element and a light-receiving element. After the distance sensor is powered on, its light-emitting element emits light, then the light is reflected by the reflector 4, and finally, according to the intensity of the reflected light received by the light-receiving element, a voltage signal is output to determine whether the distance sensor is qualified.

[0041] Among them, the reflector 4 can be white reflective paper.

[0042] Specifically, the reflector 4 is arranged inside the detection box 1 to reduce the interference of ambient light.

[0043] Among them, the reflector 4 is arranged movably inside the detection box 1 to detect different functions of the device under test. It should be noted that when detecting the light incident parameters of the device under test, move the reflector 4 so that it is arranged opposite to the device under test in the vertical direction; when detecting other parameters of the device under test, move the reflector 4 so that it is offset from the device under test in the vertical direction.

[0044] Specifically, a driving assembly 3 is provided in the detection box 1. The driving assembly 3 is used to drive the reflective sheet 4 to switch between a first position and a second position. It should be noted that when the reflective sheet 4 is switched to the first position, the reflective sheet 4 is disposed opposite to the device under test in the vertical direction; when the reflective sheet 4 is switched to the second position, the reflective sheet 4 is offset from the device under test in the vertical direction.

[0045] Among them, the driving assembly 3 includes a driving unit 31 and a cam 32. The driving unit 31 can be a motor. The cam 32 is connected to the output shaft of the motor. The motor is used to drive the cam 32 to rotate and drive the reflective sheet 4 to move through the cam 32.

[0046] Specifically, a first swing arm 321 is provided on the circumferential side of the cam 32. A first guide rail and a first limiting member are also provided in the detection box 1. The reflective sheet 4 is slidably disposed on the first guide rail and is relatively fixed to the first limiting member. When the driving unit 31 drives the cam 32 to rotate, the first swing arm 321 rotates synchronously, and the first swing arm 321 is connected to the first limiting member, and the first limiting member is used to push the reflective sheet 4 to slide on the first guide rail. It should be noted that a first card slot may be formed at the end of the first swing arm 321 connected to the first limiting member, and at least part of the first limiting member can be placed in the first card slot, so that the first swing arm 321 can abut against the first limiting member when rotating in one direction (such as clockwise), and the first swing arm 321 can also abut against the first limiting member when rotating in the other direction (counterclockwise), so as to be able to control the reflective sheet 4 to move to the first position and also control the reflective sheet 4 to move out of the first position.

[0047] Among them, as an implementation manner, the moving track of the reflective sheet 4 is linear; as another implementation manner, the moving track of the reflective sheet 4 is arc-shaped. In this embodiment, the moving track of the reflective sheet 4 is linear. When the reflective sheet 4 switches between the first position and the second position, the reflective sheet 4 moves parallel to the stage 11.

[0048] Specifically, in this embodiment, the first guide rail is linear and is provided on the lower surface of the stage 11. When the driving unit 31 drives the cam 32 to rotate counterclockwise, the first swing arm 321 rotates synchronously, and the first limiting member is used to push the reflective sheet 4 to move on the first guide rail in the direction from the second position to the first position.

[0049] In some possible implementation embodiments disclosed in the present application, as shown in Figure 3 After the device under test is placed at the opening 111 of the stage 11, the detection box 1 is closed.

[0050] It can be understood that in the present application, by setting that the detection box 1 can be closed when the device under test is placed at the opening 111 of the stage 11, the influence of external environmental factors on the detection process can be effectively reduced, and the accuracy and stability of the detection result can be ensured.

[0051] In some possible embodiments disclosed in the present application, the driving assembly 3 further includes an elastic member (not shown in the figure), a first end of the elastic member is relatively fixed to the detection box, and a second end of the elastic member is connected to the reflective sheet 4.

[0052] Wherein, the elastic member can be a tension spring.

[0053] Specifically, the elastic member is arranged in the detection box 1, a first end of the elastic member is relatively fixed to the reflective sheet 4, and a second end is relatively fixed to the detection box. It should be noted that the first end of the elastic member can be connected to the first limiting member or the reflective sheet 4, and the second end can be connected to the inner wall of the side or the bottom of the detection box 1, and the connection method can be welding or the like.

[0054] Wherein, when a first card slot is not provided at an end of the first swing arm 321 close to the first limiting member, the first swing arm 321 can only push the reflective sheet 4 to move in one direction through the first limiting member. At this time, by arranging the elastic member, the reflective sheet 4 can be pulled to move in the other direction.

[0055] In the above embodiment, when the cam 32 rotates in the first direction under the drive of the drive unit 31, the reflective sheet 4 moves from the second position towards the first position, and the elastic member accumulates elastic potential energy under the drive of the drive unit 31.

[0056] Wherein, the first direction can be the counterclockwise direction.

[0057] In the above embodiment, when the cam 32 rotates in the second direction under the drive of the drive unit 31, the elastic potential energy of the elastic member is released, and the reflective sheet 4 moves from the first position towards the second position under the action of the elastic potential energy.

[0058] Wherein, the second direction can be the clockwise direction.

[0059] In the above embodiment, when the drive unit 31 drives the cam 32 to rotate counterclockwise, the first swing arm 321 can smoothly abut against the first limiting member to push the reflective sheet 4 to move along the direction from the second position towards the first position on the first guide rail through the first limiting member. At the same time, when the drive unit 31 drives the cam 32 to rotate clockwise, the first swing arm 321 rotates in the reverse direction to cancel the pushing force on the first limiting member, and the first swing arm 321 is separated from the first limiting member. At this time, under the action of the elastic member, the reflective sheet 4 can be pulled to move along the direction from the first position towards the second position on the first guide rail.

[0060] In some possible embodiments disclosed in the present application, see Figure 2As shown in the figure, a light absorbing sheet 5 is further arranged inside the detection box 1, and a second swing arm 322 is further arranged on the circumferential side of the cam 32. When the driving unit 31 drives the cam 32 to rotate, the second swing arm 322 abuts against the light absorbing sheet 5 to drive the light absorbing sheet 5 to switch between a first position and a third position; when the light absorbing sheet 5 switches to the first position, the reflecting sheet 4 switches to the second position, and the opening 111 is located within the projection area of the light absorbing sheet 5.

[0061] It can be understood that in this application, by arranging the light absorbing sheet 5 and driving the light absorbing sheet 5 to switch between different positions through the cam 32 on the driving assembly 3 and the second swing arm 322 thereon, automatic detection can be realized, manual intervention can be reduced, the detection process can be accelerated, and the overall detection efficiency can be improved.

[0062] Among them, the light absorbing sheet 5 can be a black light absorbing paper.

[0063] Specifically, the light absorbing sheet 5 is movably arranged inside the detection box 1 to detect different functions of the device under test. It should be noted that when the light absorbing sheet 5 moves to the first position, the dark light parameter detection of the device under test can be realized; when the light absorbing sheet 5 moves to the third position, other parameter detections of the device under test can be realized.

[0064] Specifically, the light absorbing sheet 5 is also driven by the driving assembly 3. It should be noted that when the light absorbing sheet 5 switches from the first position to the third position, the reflecting sheet 4 switches from the second position to the first position; when the light absorbing sheet 5 switches from the third position to the first position, the reflecting sheet 4 switches from the first position to the second position.

[0065] Among them, the third position can be any position other than the first position and the second position, which is determined according to the moving track of the light absorbing sheet 5, and no further limitation is made in this embodiment.

[0066] Specifically, as an implementation manner, the moving track of the light absorbing sheet 5 is linear; as another implementation manner, the moving track of the light absorbing sheet 5 is arc-shaped. In this embodiment, the moving track of the light absorbing sheet 5 is linear. When the light absorbing sheet 5 switches between the first position and the third position, the light absorbing sheet 5 moves perpendicular to the stage 11, and at this time, the third position is directly below the first position.

[0067] Among them, in this embodiment, the second guide rail is linear and is arranged perpendicular to the stage 11. When the driving unit 31 drives the cam 32 to rotate clockwise, the second swing arm 322 rotates synchronously and pushes the light absorbing sheet 5 to move along the second guide rail in the direction from the third position to the first position through the second limiting member.

[0068] Specifically, a second swing arm 322 is further provided on the circumferential side of the cam 32. A second guide rail and a second limiting member are further provided in the detection box 1. The light absorbing sheet 5 is slidably arranged on the second guide rail and is relatively fixed to the second limiting member. When the driving unit 31 drives the cam 32 to rotate, the second swing arm 322 rotates synchronously, and the second swing arm 322 is connected to the second limiting member, and the second limiting member is used to push the reflecting sheet 4 to slide on the second guide rail. It should be noted that a second card slot may be formed at the end of the second swing arm 322 connected to the second limiting member, and at least part of the second limiting member can be placed in the second card slot, so that when the second swing arm 322 rotates in one direction (such as clockwise), it can abut against the second limiting member, and when the second swing arm 322 rotates in the other direction (counterclockwise), it can also abut against the second limiting member, so as to control the light absorbing sheet 5 to move to the first position and also control the light absorbing sheet 5 to move out of the first position.

[0069] In addition, the second swing arm 322 can also be arranged as follows: when the second card slot is not formed at the end of the second swing arm 322 close to the second limiting member, the second swing arm 322 can only push the light absorbing sheet 5 to move in one direction (upward direction) through the second limiting member. At this time, since the second guide rail is arranged vertically, the light absorbing sheet 5 can move in the other direction (downward direction) under the action of gravity.

[0070] In some possible implementation embodiments disclosed in the present application, as shown in Figure 2 As shown, the light absorbing sheet 5 is connected with a baffle 6. The driving assembly 3 further includes a first inductor 7 and a second inductor 8. Both the first inductor 7 and the second inductor 8 have a transmitting end and a receiving end. When the light absorbing sheet 5 switches to the first position, the baffle 6 moves between the transmitting end and the receiving end of the first inductor 7. When the light absorbing sheet 5 switches to the third position, the baffle 6 moves between the transmitting end and the receiving end of the second inductor 8.

[0071] It can be understood that in the present application, by setting the first inductor 7 and the second inductor 8, the position information of the light absorbing sheet 5 can be sensed, so as to determine the working state of the driving unit 31, which helps to achieve precise control and optimize the detection process.

[0072] Among them, the first inductor 7 and the second inductor 8 can be other components with the function of a travel switch such as a photoelectric sensor, and no further limitation is made in this embodiment.

[0073] Among them, the first inductor 7 and the second inductor 8 can be installed on the vertically arranged second guide rail.

[0074] Among them, the first inductor 7 is arranged opposite to the first position in the horizontal direction, and is used to judge whether the light absorbing sheet 5 is located at the first position; the second inductor 8 is arranged opposite to the third position in the horizontal direction, and is used to judge whether the light absorbing sheet 5 is located at the third position.

[0075] Specifically, a baffle 6 is fixedly connected to the light-absorbing sheet 5, and the baffle 6 moves synchronously with the light-absorbing sheet 5. When the light-absorbing sheet 5 moves to the first position and the baffle 6 moves between the transmitting end and the receiving end of the first sensor 7, the first sensor 7 is triggered; when the light-absorbing sheet 5 moves to the third position and the baffle 6 moves between the transmitting end and the receiving end of the second sensor 8, the second sensor 8 is triggered.

[0076] In some possible embodiments disclosed in the present application, referring to Figure 1 As shown, the detection device further includes a lifting assembly 9. The lifting assembly 9 includes a column 91. A lifting linear guide 92 is provided on one side of the column 91 close to the connector 2. A mounting block 93 is slidably arranged on the lifting linear guide 92, and the connector 2 is relatively fixed to the mounting block 93; the lifting assembly 9 further includes a driving arm 94, a first transmission arm 95, and a second transmission arm 96. The driving arm 94 and the first transmission arm 95 are sleeved on the same rotating shaft. One end of the second transmission arm 96 is hinged to the first transmission arm 95, and the other end of the second transmission arm 96 is hinged to the mounting block 93.

[0077] It can be understood that in the present application, by providing the lifting linear guide 92, it can ensure that the mounting block 93 and the connector 2 connected thereto move along a straight line during the lifting process, reducing shaking and deviation, so as to achieve accurate and stable lifting actions, which helps to improve the accuracy and stability of detection; at the same time, through the combined transmission of the driving arm 94, the first transmission arm 95, and the second transmission arm 96, the driving force can be effectively transmitted to the mounting block 93 to realize the lifting of the connector 2. This transmission method can achieve a large stroke in a relatively small space, improving the space utilization rate of the device.

[0078] Specifically, in this embodiment, when the driving arm 94 is lifted, the driving arm 94 drives the first transmission arm 95 to rotate around the rotating shaft through the rotating shaft. At this time, the end of the first transmission arm 95 far from the rotating shaft has a tendency to move upward, thereby driving the second transmission arm 96 hinged to the first transmission arm 95 to move upward. At the same time, the second transmission arm 96 drives the connector 2 to rise through the hinged mounting block 93. When the driving arm 94 is pressed down, the driving arm 94 drives the first transmission arm 95 to rotate around the rotating shaft through the rotating shaft. At this time, the end of the first transmission arm 95 far from the rotating shaft has a tendency to move downward, thereby driving the second transmission arm 96 hinged to the first transmission arm 95 to move downward. At the same time, the second transmission arm 96 drives the connector 2 to descend through the hinged mounting block.

[0079] In some possible embodiments disclosed in the present application, referring to Figure 1 and Figure 2As shown, a plurality of connectors 2 are provided. The plurality of connectors 2 include a first connector 2 and a second connector 2. The first connector 2 is used to abut against the pins of the device under test, and the second connector 2 is used to abut against the housing of the device under test.

[0080] It can be understood that in this application, the first connector 2 abuts against the pins of the device under test, which can realize the electrical connection and detection of the internal circuit of the device under test and obtain the performance parameters of the core circuit; the second connector 2 abuts against the housing of the device under test, which can detect problems such as leakage and static electricity accumulation on the housing to ensure the safety and electromagnetic compatibility of the device.

[0081] Among them, the first connector 2 abutting against the pins of the device under test can be used to detect the light input parameters and dark light parameters of the device under test.

[0082] Among them, the second connector 2 abutting against the housing of the device under test can be used to detect the conductive ability of the housing and effectively prevent static interference.

[0083] In some possible implementation embodiments disclosed in this application, the detection device further includes a human-machine interaction module, and the detection circuit is electrically connected to the human-machine interaction module.

[0084] It can be understood that in this application, by setting the human-machine interaction module and electrically connecting the human-machine interaction module to the detection circuit, the operator can intuitively understand the working state, detection parameters and results of the detection device through the human-machine interaction module, which is convenient for real-time monitoring of the detection process.

[0085] Among them, the human-machine interaction module may include a display screen and an alarm, etc. The display screen can display different colors, and the alarm can emit a buzzing sound to facilitate the operator to quickly judge the detection result of the device under test.

[0086] Specifically, in this embodiment, the display screen showing red represents that the device under test is detected to be defective, and vice versa represents that the device under test is a good product.

[0087] In the detection device provided in the embodiment of this application, by providing the connector 2 on the stage 11 in a liftable manner, it can better adapt to devices under test of different sizes and specifications, ensure stable electrical connection, and reduce detection errors and unstable factors caused by poor contact; at the same time, by setting the driving component 3, and driving the reflecting sheet 4 and the light absorbing sheet 5 to switch at different positions through the cam 32 of the driving component 3 and the swing arm thereon, automatic detection can be realized, manual intervention can be reduced, the detection process can be accelerated, and the overall detection efficiency can be improved.
