The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.
[0028] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.
[0029] Currently, in the processing of transparent materials, the process is usually monitored manually to prevent the material strip from breaking or running out of material. However, manual inspection often fails to detect problems in time, which can lead to the transparent material entering the equipment rollers after the material strip breaks or runs out of material, causing equipment damage and increasing product production costs. Furthermore, the locations where the material strip needs to be inspected are not centralized or uniform, so multiple employees are usually required to monitor the material strip, resulting in excessively high labor costs.
[0030] Based on this, this application proposes a detection device and equipment that can automatically detect and monitor the material belt. By using a distance sensor 190, it can promptly identify whether the material belt is broken or lacking material, thereby reducing labor costs and preventing material from entering the equipment rollers and causing damage to the equipment, thus reducing production costs.
[0031] It is understood that the detection device in this application embodiment includes a circuit board 120, a distance sensor 190, a heat sink, and a housing. A connector 130 is provided on one side of the circuit board 120. The distance sensor 190 is connected to the circuit board 120 through the connector 130 and is used to detect whether the material strip is broken. A relay 140 is provided on the side of the circuit board 120 where the connector 130 is provided. The housing includes a bottom box 100 and a top cover 110. The bottom box 100 is provided with a slot 101. The circuit board 120, the connector 130, and the relay 140 are provided in the slot 101. A first opening 102 is provided on the side wall of the slot 101. The distance sensor 190 is provided outside the slot 101. The data line of the distance sensor 190 passes through the first opening 102 and is connected to the connector 130. The top cover 110 is detachably closed to the slot 101.
[0032] The beneficial effects of the detection device in this application embodiment are as follows: the circuit board 120 facilitates the integration of various components, enabling unified management of each component. Compared to the traditional technology of directly connecting the ranging sensor 190 to the circuit board 120, the connection between the ranging sensor 190 and the circuit board 120 via the connector 130 facilitates the orderly connection of the ranging sensor 190, avoiding the messy and difficult-to-manage wiring caused by directly connecting the ranging sensor 190 to the circuit board 120. The ranging sensor 190 is used to detect the material strip. When the ranging sensor 190 does not receive a returned signal within a specified time, it can be considered that the material strip has an edge breakage, and then... No manual inspection is required, saving labor costs. The relay 140 allows for timely shutdown of the equipment when the distance sensor 190 detects a break in the conveyor belt, largely preventing material from entering the rollers, extending the equipment's lifespan, and reducing processing costs. The circuit board 120, connector 130, and relay 140 are encapsulated within the housing, providing them with some protection. The distance sensor 190 is located outside the housing and connected to the connector 130 inside the housing via its data cable, making the use of the distance sensor 190 more flexible and convenient.
[0033] For example, in some embodiments, reference is made to Figure 1 and Figure 4In this embodiment, connector 130 and relay 140 are both located on the same side of circuit board 120, facilitating centralized setup and management of components. Circuit board 120, connector 130, and relay 140 are all located within slot 101 of the base box 100, while distance sensor 190 is located outside slot 101. A first opening 102 is located on the side wall of slot 101. The data line of distance sensor 190 passes through the first switch and connects to connector 130, thereby connecting distance sensor 190 to circuit board 120. The placement of connector 130 makes the connection between distance sensor 190 and circuit board 120 simpler and more standardized, and the distance sensor... The connection of sensor 190 to connector 130 via data cable makes the use of distance sensor 190 more flexible, allowing distance sensor 190 to be extended to various parts of the device under test for detection. Top cover 110 can be detachably closed onto slot 101, so that circuit board 120, connector 130 and relay 140 are encapsulated in slot 101, thereby protecting circuit board 120, connector 130 and relay 140 from accidental bumps during automatic detection, or from excessive impurities entering slot 101, which would cause circuit board 120 and connector 130 to malfunction, thus affecting the detection effect. The distance sensor 190 performs real-time detection on the material strip. When the distance sensor 190 measures that the time it takes for the output signal to be reflected back to the distance sensor 190 from the material strip exceeds a preset threshold time, it is determined that the material strip of the tested equipment has an edge breakage or material shortage. Then, the relay 140 controls the tested equipment to stop to prevent the tested equipment from continuing to run and causing material to enter the rollers of the tested equipment, thereby causing unnecessary damage to the tested equipment.
[0034] It is understood that: the circuit board 120 is provided with a terminal block 160 on the side where the connector 130 is provided, and the slot 101 is provided with a second opening 103 corresponding to the terminal block 160. The second opening 103 and the first opening 102 are respectively located on opposite sides of the slot 101.
[0035] For example, in some embodiments, reference is made to Figure 1 In this embodiment, the terminal block 160 is model KF128. The terminal block 160 and the relay 140 are located on the same side of the circuit board 120. The relay 140 is connected to the device under test through the terminal block 160, which makes the connection between the relay 140 and the device under test more standardized and stable, and also makes it easier for the terminal block 160 to draw power from the device under test, thereby providing power to the detection device of this application.
[0036] It is understood that connector 130 includes multiple ports, and distance sensors 190 are provided with multiple ports, with each port used to connect two distance sensors 190.
[0037] For example, in some embodiments, reference is made to Figure 1 and Figure 2 In this embodiment, connector 130 is an RJ45 connector 130 with four ports. There are eight ranging sensors 190, and each port is connected to two ranging sensors 190, which makes the connection of the ranging sensors 190 more orderly and easier for operators to manage.
[0038] It should be noted that the range sensor 190 has an I2C interface.
[0039] It is understood that the detection device of this application also includes an indicator light assembly, which is located on the side of the circuit board 120 where the connector 130 is located, and the top cover 110 has a third opening 111, in which the indicator light assembly is engaged.
[0040] For example, in some embodiments, reference is made to Figure 1 and Figure 2 In this embodiment, the top cover 110 is provided with a rectangular third opening 111. The indicator light 150 and the connector 130 are located on the same side of the circuit board 120. The indicator light assembly is engaged with the third opening 111 so as to protect the indicator light assembly and also make it convenient for the operator to observe the status of the indicator light assembly through the third opening 111.
[0041] It is understandable that the indicator light assembly has multiple indicator lights 150, and each indicator light 150 corresponds to a multiple ranging sensor 190. The indicator lights 150 are used to reflect the working status of the corresponding ranging sensor 190.
[0042] For example, in some embodiments, reference is made to Figure 2 In this embodiment, the indicator light assembly includes multiple indicator lights 150. The number of indicator lights 150 corresponds to the distance measuring sensor 190, with one distance measuring sensor 190 corresponding to one indicator light 150. When the distance measuring sensor 190 detects normal operation, i.e., there is no material edge breakage or material shortage, the indicator light 150 lights up green. When the distance measuring sensor 190 detects material edge breakage or material shortage, the indicator light 150 switches to red, thereby prompting the operator and facilitating timely handling of the fault.
[0043] It is understood that the detection device of this application also includes a main control board 170, which is located on the side of the circuit board 120 where the connector 130 is located, and the main control board 170 and the circuit board 120 are detachably connected.
[0044] For example, in some embodiments, reference is made to Figure 1In this embodiment, the main control board 170 is model RP2040. The main control board 170 is located on the side of the relay 140 away from the terminal block 160. The circuit board 120 is provided with multiple support pillars, and the main control board 170 is provided with multiple fixing holes. The multiple support pillars correspond one-to-one with the multiple fixing holes. The main control board 170 is detachably connected to the circuit through the fixing holes and support pillars, so as to facilitate the replacement of the main control board 170 in the future. Setting up the main control board 170 makes it easy to control components such as the ranging sensor 190 and the relay 140 through the logic of the main control board 170.
[0045] It is understandable that the main control board 170 has a reset button 171 and a calibration button 172 on the side away from the circuit board 120. The top cover 110 has a first through hole 112 and a second through hole 113. The first through hole 112 corresponds to the reset button 171, which is located directly below the first through hole 112. The second through hole 113 corresponds to the calibration button 172, which is located directly below the second through hole 113.
[0046] For example, in some embodiments, reference is made to Figure 1 and Figure 3 In this embodiment, the reset button 171 and the calibration button 172 are located on the side of the main control board 170 away from the circuit board 120. The first through hole 112 is located directly above the reset button 171, so that the reset button 171 is located inside the housing. This avoids accidental activation of the reset button 171 without affecting its use. Similarly, the second through hole 113 is located directly above the calibration button 172, so that the calibration button 172 is located inside the housing. This avoids accidental activation of the calibration button 172 without affecting its use. After the ranging sensor 190 is plugged in or unplugged, the reset button 171 needs to be pressed manually to reset the system of the detection device of this application. This prevents the system from crashing due to the sudden plugging and unplugging of the ranging sensor 190 during operation, which would affect the detection effect of the ranging sensor 190. The calibration button 172 is used to manually set the threshold time. When the ranging sensor 190 is used to detect the material belt, the calibration button 172 can be pressed and held. The system of the detection device of this application will then use the time sensed by the ranging sensor 190 at this time as the threshold time. The time sensed by the ranging sensor 190 is the time from the transmission of the signal to the reception of the reflected signal. Once this threshold time is exceeded, the tested equipment will be stopped, which makes the setting of the threshold time simpler and more accurate.
[0047] It is understandable that the range sensor 190 is a laser range sensor 190.
[0048] For example, in some embodiments, the ranging sensor 190 is a laser ranging sensor 190 using the time-of-flight method. By emitting laser pulses and measuring the time difference of the reflected light's return, the distance is calculated by combining the light speed. When the material of the device being measured is transparent, the laser ranging sensor 190 using the time-of-flight method can accurately detect the distance between the transparent material and the ranging sensor 190. In contrast, traditional infrared sensors used for ranging cannot measure the distance to transparent materials. Therefore, the laser ranging sensor 190 using the time-of-flight method makes the detection device of this application applicable to a wider range of scenarios.
[0049] It is understood that the detection device of this application also includes a buzzer 180, which is located on the side of the circuit board 120 where the main control board 170 is located, and is located between the main control board 170 and the connector 130.
[0050] For example, in some embodiments, reference is made to Figure 3 In this embodiment, the buzzer 180 and the main control board 170 are located on the same side of the circuit board 120. When the distance sensor 190 senses for a time exceeding the threshold time, that is, when it detects that the material belt has an edge break or lacks material, the buzzer 180 will simultaneously emit an audible reminder to remind the operator to take relevant actions. This avoids the situation where the operator cannot promptly handle the tested equipment part with an edge break or lack of material due to ignoring the prompt of the indicator light 150, which could lead to the material belt entering the roller of the tested equipment.
[0051] The specific working principle of the detection device in this application is as follows:
[0052] Eight laser rangefinders 190 detect eight different areas of the device under test, with each rangefinder 190 detecting 8 to 10 times per second, thus achieving real-time detection. A threshold time is set, assuming a threshold time of 400 seconds. When one or more of the eight laser rangefinders 190 sense the material for more than 400 seconds, indicating that the detected area has a broken or missing material edge, the emitted laser pulse cannot be reflected back to the rangefinder 190. This causes the sensing time of the rangefinder 190 to continuously increase, eventually exceeding the threshold time of 400 seconds. At this point, the indicator light 150 corresponding to the rangefinder 190 switches from green to red, the buzzer 180 sounds an alarm, and the relay 140 controls the device under test to stop. This achieves automatic detection of broken or missing material edges of the material belt and timely shutdown of the device under test, saving labor costs while effectively protecting the device and preventing the material belt from entering the rollers of the device under test.
[0053] The detection device according to the second aspect of the application includes the detection apparatus of the first aspect of the application described above.
[0054] According to the detection equipment of this application embodiment, the circuit board 120 facilitates the integration of various components for unified management. A connector 130 connects the ranging sensor 190 to the circuit board 120, ensuring orderly connection of the ranging sensor 190 and avoiding the messy and difficult-to-manage wiring caused by directly connecting the ranging sensor 190 to the circuit board 120. The ranging sensor 190 is used to detect the material strip. When the ranging sensor 190 does not receive a return signal within a specified time, it can be considered that the material strip has an edge breakage, thus eliminating the need for manual inspection and saving labor costs. The relay 140 facilitates the detection of the ranging sensor 190 when it receives a return signal. The device stops operation promptly upon detecting a break in the conveyor belt, significantly reducing the risk of material entering the rollers, extending the equipment's lifespan, and lowering processing costs. The circuit board 120, connector 130, and relay 140 are encapsulated within a housing, providing them with protection. The distance sensor 190 is located outside the housing and connected to the connector 130 inside via its data cable, making its use more flexible and convenient. By introducing the detection device of this application, conveyor belt breakage no longer requires manual detection, further reducing labor costs.
[0055] Since the detection equipment includes the detection device of the first aspect embodiment, the corresponding contents of the detection device in the first aspect embodiment can be applied to the detection equipment of the second aspect, and have the same implementation principle and technical effect. To avoid redundancy, it will not be described in detail here.
[0056] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
