[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0026] Currently, the life test machines for photoelectric sensors on the market cannot test the life of diffuse reflection photoelectric sensors. In addition, the life test machines on the market cannot monitor the digital output of products in real time during the test, and it is necessary to disassemble the photoelectric sensor to check whether the output function is normal. Therefore, the above-mentioned life test machines cannot detect whether the output of the photoelectric sensor during the test is normal, nor can they detect temporary abnormalities. In addition, the test efficiency of the life test machines on the market is relatively low, the test cycle is long, and the user experience is poor.

[0027] Based on this, an embodiment of the present invention provides a life test device and system, specifically providing an intelligent life test machine for diffuse reflection photoelectric switch sensors, which can be applied to the reliability life test of diffuse reflection photoelectric switch sensors. The test machine system provided in this embodiment is jointly composed of a host computer and a slave computer, and they cooperate with each other to achieve efficient testing of diffuse reflection photoelectric sensors and real-time monitoring of the product output status.

[0028] To facilitate the understanding of this embodiment, a life test device disclosed in the embodiments of the present invention will be introduced in detail first.

[0029] Embodiment 1:

[0030] An embodiment of the present invention provides a life test device. Refer to Figure 1 the structural schematic diagram of a life test device as shown. The life test device includes: a test machine mechanism, a groove-type photoelectric switch, a signal processing module, and a control module; the test machine mechanism, the groove-type photoelectric switch, and the signal processing module are all communicatively connected to the control module.

[0031] The test machine mechanism is used to fix the photoelectric sensor to be tested and intermittently reflect light signals to the photoelectric sensor; the photoelectric sensor is used to output test signals based on the intermittent light signals; the signal processing module is used to collect the test signals and send the test signals to the control module; the groove-type photoelectric switch is used to output switch signals and send the switch signals to the control module; wherein, the switch signal characterizes the intermittent output situation of the light signal; the control module is used to determine whether the life test device and the photoelectric sensor are both in a normal output state based on the test signals and the switch signals.

[0032] The photoelectric sensor in this embodiment can be a diffuse reflection photoelectric switch sensor, and the control module in this embodiment can be a PLC (Programmable Logic Controller). The photoelectric sensor can be arranged in the testing machine mechanism. The testing machine mechanism intermittently reflects light signals to the photoelectric sensor. When the photoelectric sensor receives the light signal, it can feedback a test signal. The test signal is received by the signal processing module, and the signal processing module sends the test signal to the control module.

[0033] The switch signal output by the slot photoelectric switch can characterize the intermittent output situation of the light signal, which can be: only when the light signal is output, the slot photoelectric switch will output the switch signal. The control module can obtain the switch signal.

[0034] Therefore, the control module can determine whether both the life testing device and the photoelectric sensor are in the normal output state based on the test signal and the switch signal. For example: if the test signal and the switch signal increase or decrease intermittently at the same time, it can be understood that both the life testing device and the photoelectric sensor are in the normal output state. If the test signal and the switch signal are not synchronized, or do not increase or decrease intermittently, it can be understood that at least one of the life testing device and the photoelectric sensor is not in the normal output state.

[0035] A life testing device provided by an embodiment of the present invention, wherein the testing machine mechanism intermittently reflects light signals to the photoelectric sensor; the photoelectric sensor outputs a test signal based on the intermittent light signal; the signal processing module collects the test signal and sends the test signal to the control module; the slot photoelectric switch outputs a switch signal characterizing the intermittent output situation of the light signal and sends the switch signal to the control module; the control module determines whether both the life testing device and the photoelectric sensor are in the normal output state based on the test signal and the switch signal. In this way, efficient testing can be carried out for diffuse reflection photoelectric sensors, and the output state of the photoelectric sensor can be monitored in real time, providing a high user experience.

[0036] Embodiment 2:

[0037] Another life testing device provided by an embodiment of the present invention is shown in Figure 2 the front view of a life testing device shown in Figure 3 the side view of a life testing device shown in Figure 4 and the top view of a life testing device shown in Figures 2 - 4 As shown in Figures 2 - 4 the life testing device further includes: a servo motor, which is communicatively connected to the control module. The testing machine mechanism includes a base, a turntable rotating device, and a test product fixing device; the photoelectric sensor is installed on the test product fixing device, and the slot photoelectric switch is installed on the turntable rotating device; the turntable rotating device includes a turntable; the turntable includes a black area and a white area; the servo motor is used to control the rotation of the turntable.

[0038] If the optical axis between the optical signal and the photoelectric sensor is blocked by the white area, the photoelectric sensor outputs a first test signal; if the optical axis is blocked by the black area, the photoelectric sensor outputs a second test signal; if the optical axis is blocked by the white area, the slot-type photoelectric switch outputs a first switch signal; if the optical axis is blocked by the black area, the slot-type photoelectric switch outputs a second switch signal.

[0039] The life test device of this embodiment can be used for the reliability life test of diffuse reflection photoelectric sensors. As Figures 2 - 4 shown, the mechanism part of this embodiment includes a base, a turntable rotation device, and a test product fixing device; the electrical control part is composed of a host computer, a lower computer (PLC, industrial control touch screen, etc.), and control components (servo motors).

[0040] The life test device drives the turntable to rotate, and the rotation speed can be accurately controlled. The surface of the turntable is a matte white paper (the standard detection material for diffuse reflection photoelectric sensors). As Figure 2 shown, the white paper is divided into 4 equal parts in a whole circle and printed in black and white alternately. When the optical axis of the test product (i.e., the photoelectric sensor) is in the white area position, it receives normal reflected light and outputs ON (in the default setting, i.e., the first test signal); when the optical axis of the test product is in the black area position, due to the light absorption of the black, it can only receive a very small amount of reflected light and outputs OFF (in the default setting, i.e., the second test signal). Therefore, the turntable only needs to rotate in one direction to achieve the alternating output of ON / OFF of the diffuse reflection photoelectric sensor, that is, the alternating output of the first test signal and the second test signal.

[0041] Among them, the control module can monitor the real-time output status of various test products at their respective test voltage levels through the connected signal processing module. In addition, the control module can control the operation of the servo motor through a program and can also receive the first switch signal and the second switch signal sent by the slot-type photoelectric switch.

[0042] Specifically, the photoelectric sensors in this embodiment are symmetrically installed on both sides along the horizontal vertical line of the central axis of the turntable. 3 photoelectric sensors can be installed on one side, and 6 photoelectric sensors can be tested simultaneously. This installation can greatly reduce the size of the turntable, thereby reducing the motor power and the volume of the equipment.

[0043] Specifically, a slide rail is provided on the base of the test machine mechanism of this embodiment, and the test product fixing device slides along the slide rail to adapt to the test of diffuse reflection photoelectric sensor products with different detection distances.

[0044] Specifically, the life test device of this embodiment further includes: an industrial control touch screen, which is communicatively connected to the control module; the industrial control touch screen is used to respond to the user's parameter setting operation to determine the first test parameter of the life test device; the servo motor controls the turntable to rotate based on the first test parameter; the industrial control touch screen is further used to respond to the user's output display operation, obtain the test signal and the switch signal from the control module, and display the test signal and the switch signal.

[0045] The control module (such as a PLC) can be connected to the industrial control touch screen through the RS232 serial port to interact interface data. The tester can set parameters such as the test speed, the test target cycle, and the detection feedback type on the industrial control touch screen interface, view the current test status, and operate the start and stop of the device.

[0046] In addition, if the life test device or the photoelectric sensor is not in the normal output state, the control module is further used to send an alarm signal. The alarm signal can be a sound signal or a light signal to remind the user to discover it as soon as possible.

[0047] Embodiment Three:

[0048] An embodiment of the present invention provides a life test system. Refer to Figure 5 the structural schematic diagram of a life test system shown. The life test device includes: a host computer and a life test device; the host computer is used to send the second test parameter to the life test device; the tester mechanism of the life test device is used to intermittently adjust and reflect a light signal to the photoelectric sensor based on the second test parameter.

[0049] The tester can also set test parameters such as the test target cycle, speed, and feedback detection type as the second test parameter on the Labview (Laboratory Virtual Instrument Engineering Platform) software interface of the host computer, and write them into the PLC (i.e., the control module) of the lower computer through the USB to RS232 serial port. The lower computer PLC controls the servo motor to drive the turntable to rotate through the program and the set parameters, so that the test product works alternately between normal reflected light and extremely little reflected light.

[0050] The PLC of the lower computer can set the target test cycle through the program for automatic cyclic testing, collect the feedback signal of the test product, automatically judge the test result, and upload the test data to the host computer, and then the host computer transmits it to the server.

[0051] Specifically, while the PLC of the lower computer collects the ON / OFF output signal (i.e., the test signal) of the test product through the signal processing module, it also collects the switch signal of the groove-shaped photoelectric switch installed on the turntable rotating device to determine whether the test product is in the white area or the black area of the turntable, and further determine whether the output of the test product is normal. Once the test is abnormal, the test will be stopped immediately, an alarm sound will be emitted to prompt the staff to check the test site in time, and it will be uploaded to the upper computer.

[0052] A life test device provided by an embodiment of the present invention provides a diffuse reflection photoelectric sensor life test device jointly controlled by an upper computer and a lower computer, which can realize the reliability test of the diffuse reflection photoelectric sensor; can realize an efficient test with 50 alternations per second; can detect the ON / OFF output state of the product in real time, and trigger an alarm immediately when the output is abnormal; can monitor the device operation and the test interface in real time. An intelligent life test device for a diffuse reflection photoelectric sensor integrating the above functions.

[0053] In this embodiment, a servo motor can be used to drive the turntable to rotate, and the test speed can be accurately controlled and digitally set. The surface of the turntable provided in this embodiment is a matte white paper (the standard detection material for diffuse reflection photoelectric switches), and the whole circle of the white paper is divided into four equal parts and printed in black and white alternately. The turntable only needs to rotate in one direction to realize the ON / OFF alternating output of the diffuse reflection photoelectric sensor.

[0054] In this embodiment, 6 photoelectric sensors can be tested simultaneously. The photoelectric sensors are symmetrically installed on both sides along the horizontal vertical line of the turntable central axis on the test product fixing device, and 3 photoelectric sensors can be installed on one side, which can greatly reduce the turntable size, thereby reducing the motor power and the device volume. In this embodiment, a slide rail can be provided on the base, and the test product fixing device can slide freely on the slide rail to adapt to the test of diffuse reflection photoelectric sensor products with different detection distances.

Refer to Figure 6 As shown in the schematic diagram of a life test system, the life test device further includes: a server, and the server is connected to the upper computer; the upper computer is further used to send the test signal and the switch signal to the server. The upper computer can be connected to the server through Ethernet and upload the test signal and the switch signal as test data.

[0057] Specifically, the control module of the life test device is further used to send the test signal and the switch signal to the upper computer; the upper computer is further used to draw a test chart of the photoelectric sensor based on the test signal and the switch signal.

[0058] The host computer can communicate interactively with the control module through the USB to RS232 interface to obtain test signals and switch signals. After obtaining the test signals and switch signals uploaded by the control module, an intuitive curve chart can be formed on the control interface of the host computer and uploaded to the server for relevant personnel to view.

[0059] like Figure 6 As shown, the life test system also includes a camera device, which is connected to the server; the camera device is used to collect the test video of the life test device and send the test video to the server.

[0060] The camera device may be a CCD (Charge-coupled Device) camera, which may be connected to a server via Ethernet, and the test conditions recorded by the CCD may be uploaded to the server so that a user may record and remotely view the test conditions.

[0061] The operation of the life test system can be remotely monitored through the camera device. In this way, the current test situation and the test situation of each previous time period can be observed in real time when away from home.
