Description

Technical Field

[0001] This utility model relates to the field of photoelectric sensor detection technology, specifically to a photoelectric sensor detection fixture and a photoelectric sensor detection system. Background Technology

[0002] In the production process of photoelectric sensors, it is necessary to test whether the quality of the photoelectric sensors is up to standard. This includes a very important step: testing the aging characteristics of the photoelectric sensors.

[0003] During high-temperature aging testing of photoelectric sensors, operators need to connect the sensor to a testing fixture, place it in a high-temperature heating chamber, and turn on the power to ensure the emitting side of the sensor emits light and the receiving side is fully conductive. The conductive current on the receiving side is then converted into voltage through a circuit, and then fed into a D flip-flop via a comparator circuit. The data from the D flip-flop is used to determine whether the photoelectric sensor experiences a momentary open circuit in the high-temperature environment, thereby judging the sensor's high-temperature aging electrical characteristics. This high-temperature aging testing process is overly cumbersome and has low testing efficiency. Utility Model Content

[0004] To at least partially address the problems existing in the prior art, according to one aspect of the present invention, a photoelectric sensor detection fixture is provided. The photoelectric sensor detection fixture includes a main body, a mounting component, a conductive component, and a display connector for connecting to an external display component. The mounting component is disposed on the main body and has a first mounting portion for mounting a device under test (DUT) and a second mounting portion for mounting a mating component. The first and second mounting portions are disposed opposite to each other. The main body is provided with a main electrical component for communicating with the mating component. The conductive component includes a first connecting end and a second connecting end that are connected to each other. The first connecting end communicates with the display connector, and the second connecting end has a conductive position and a disconnect position relative to the first mounting portion. When the second connecting end is in the conductive position, it contacts the DUT to connect the DUT and the display connector. When the second connecting end is in the disconnect position, it is spaced apart from the DUT to disconnect the DUT from the display connector.

[0005] The photoelectric sensor testing fixture provided in this application connects to an external display via a conductive component and a display connector. The status of the external display allows the user to determine whether the tested part is good or bad. The overall testing circuit is simpler and the testing efficiency is higher. The second connection end has a conductive station and a disconnect station relative to the first mounting part, making the on / off control of the testing circuit more convenient and further improving testing efficiency.

[0006] For example, the mounting component is movably connected to the body so that the second connecting end can move relative to the first mounting part between the connecting station and the separating station.

[0007] For example, the main body is provided with a folding limiting member, which has a limiting position and a free position relative to the main body. When the second connecting end is in the separation position, the folding limiting member is attached to the main body to make the mounting part movable. When the second connecting end is in the conduction position, at least a part of the structure of the folding limiting member is separated from the main body and abuts against the mounting part.

[0008] For example, the folding limiter is located on the side of the mounting member away from the first mounting part.

[0009] For example, there are multiple first mounting parts and multiple second mounting parts, and one first mounting part and one second mounting part constitute a detection unit. There are multiple second connection ends, which are set one-to-one with the detection unit.

[0010] For example, multiple second connection ends are connected in series with each other.

[0011] For example, the photoelectric sensor detection fixture includes multiple mounting components, all of which are connected to the main electrical components, and each mounting component is provided with a conductive component and a display connector.

[0012] For example, the connector includes a luminaire.

[0013] According to another aspect of this utility model, a photoelectric sensor detection system is also provided. This photoelectric sensor detection system includes a detection machine and any of the aforementioned photoelectric sensor detection fixtures. The detection machine is equipped with a display element, which is connected to a conductive element via a display connector.

[0014] For example, there are multiple photoelectric sensor detection fixtures, and each fixture is connected to at least one display.

[0015] This utility model description introduces a series of simplified concepts, which will be further explained in detail in the detailed description section. This utility model description is not intended to limit the key features and essential technical features of the claimed technical solution, nor is it intended to limit the scope of protection of the claimed technical solution.

[0021] In the following description, numerous details are provided to enable a thorough understanding of the present invention. However, those skilled in the art will appreciate that the following description merely illustrates preferred embodiments of the present invention, which may be practiced without one or more of these details. Furthermore, to avoid confusion with the present invention, some technical features well-known in the art have not been described in detail.

[0022] To fully understand the embodiments of this utility model, a detailed structure will be presented in the following description. Obviously, the implementation of the embodiments of this utility model is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of this utility model are described in detail below; however, in addition to these detailed descriptions, this utility model may have other embodiments.

[0023] This embodiment of the invention provides a photoelectric sensor detection fixture. (Refer to...) Figure 1The photoelectric sensor detection fixture 10 may include a main body 110, a mounting member 120, a conductive member 130, and a display connector for connecting to an external display. The mounting member 120 may be disposed on the main body 110, and may have a first mounting portion 1210 for mounting a device under test (DUT) and a second mounting portion 1220 for mounting a mating component. The first mounting portion 1210 and the second mounting portion 1220 may be disposed opposite to each other. The mounting member 120 is used to mount the DUT and the mating component. The DUT can be either a transmitter or a receiver, and the mating component corresponds to the other of the transmitter and receiver. For example, the DUT is a transmitter, and the mating component is a receiver. The main body 110 may be provided with a main electrical component for communicating with the mating component. The main electrical component can supply power to the mating component. Exemplarily, the main electrical component may be a circuit board, which communicates with the mating component, i.e., allows the mating component to be energized. The conductive element 130 may include a first connecting end 1310 and a second connecting end 1320 that are connected to each other. The first connecting end 1310 may be connected to a display connector, and the second connecting end 1320 may have a connection position and a separation position relative to the first mounting portion 1210. The different positions of the second connecting end 1320 relative to the first mounting portion 1210 may be achieved by moving the second connecting end 1320, or by moving the first mounting portion 1210 (i.e., moving the device under test), as long as the relative movement of both is ensured. The conductive element 130 may be a PIN pin. One end of the PIN pin (i.e., the second connecting end 1320) may extend into the device under test and be electrically connected to the device under test, while the other end (i.e., the first connecting end 1310) is connected to the display connector. The display connector may be any device that can electrically connect an external display and the conductive element 130. For example, the display connector may include a circuit board and wires connected to the circuit board, with the first connecting end 1310 connected to the circuit board and the wires connecting the circuit board and the display.

[0024] When the second connection terminal 1320 is in the conducting position, it can contact the device under test (DUT) to connect the DUT and the display connector. When the second connection terminal 1320 is in the disengaging position, it can be separated from the DUT to disconnect it from the display connector. It can be understood that the main electrical component and the mating component form one part of the detection circuit, while the DUT, the conducting component 130, and the display connector form the other part. When the DUT and the mating component are working normally, both parts of the detection circuit are connected, meaning the entire detection circuit is connected. At this time, the display connected to the display connector is also energized. When the DUT and the mating component cannot work normally, both parts of the detection circuit are disconnected, meaning the detection circuit is open, and the display is not energized. In other words, the state of the DUT can be determined by the state of the display, thus determining whether the DUT is a good product.

[0025] The testing process can be as follows: The component under test (DUT) is installed onto the first mounting part 1210, and the mating part is installed onto the second mounting part 1220. The main electrical component is connected to the mating part. The second connecting end 1320 is in a separated position relative to the first mounting part 1210. Then, the second connecting end 1320 is placed in a conductive position relative to the first mounting part 1210, at which point the detection circuit is conductive. The photoelectric sensor detection fixture 10 is placed in a high-temperature environment, and the status of the DUT is determined by the display status. The process is maintained for a predetermined time (which can be 10 minutes). Powering on the display indicates that the DUT is good, and powering off indicates that the DUT is defective.

[0026] The photoelectric sensor detection fixture 10 provided in this application is connected to an external display via a conductive member 130 and a display connector. The status of the external display can indicate whether the tested part is a good product. The overall detection circuit is simpler and the detection efficiency is higher. The second connection end 1320 has a conductive station and a disconnect station relative to the first mounting part 1210, making the on / off control of the detection circuit more convenient and further improving detection efficiency.

[0027] For example, refer to Figure 1 The mounting component 120 is movably connected to the main body 110, allowing the second connecting end 1320 to move relative to the first mounting portion 1210 between a connection station and a separation station. In other words, the movement of the mounting component 120 drives the movement of the first mounting portion 1210 and the device under test within it, thereby achieving the switching of the second connecting end 1320 relative to the first mounting portion 1210 between different stations. During this station switching process, the second connecting end 1320 remains stationary relative to the main body 110, while the mounting component 120 moves relative to the main body 110. The movement of the mounting component 120 can be achieved by manual pushing. This configuration avoids the movement of the second connecting end 1320, allowing the positions of the connecting component 130 and the devices connected to it to be fixed, resulting in a simpler overall structure. In an embodiment not shown, the connecting component is movably connected to the main body, while the mounting portion is fixed relative to the main body. The movement of the connecting component enables the second connecting end to move relative to the first mounting portion between the connection station and the separation station.

[0028] For example, refer to Figure 1A folding limiting member 140 may be provided on the main body 110. The folding limiting member 140 may have a limiting position and a free position relative to the main body 110. When the second connecting end 1320 is in the separation position, the folding limiting member 140 can fit against the main body 110 to make the mounting part 120 movable. When the second connecting end 1320 is in the conduction position, at least a part of the structure of the folding limiting member 140 can separate from the main body 110 and abut against the mounting part 120. The folding limiting member 140 is provided so that when the mounting part 120 moves to the point where the test piece in the first mounting part 1210 contacts the second connecting end 1320, the folding limiting member 140 abuts against the mounting part 120 to limit the mounting part 120, so that the second connecting end 1320 is in stable contact with the test piece. This configuration ensures the smooth movement of the mounting component 120 and the stable contact between the conductive component 130 and the component under test during the testing process, thus guaranteeing the continuity stability of the testing circuit.

[0029] For example, refer to Figure 1 The folding stop 140 can be disposed on the side of the mounting member 120 away from the first mounting portion 1210. This can be understood as the conductor 130 and the folding stop 140 being located on opposite sides of the mounting member 120. The folding stop 140 can apply a pushing force to the mounting member 120 to ensure stable contact between the second connecting end 1320 and the device under test.

[0030] For example, refer to Figure 1 There can be multiple first mounting portions 1210 and second mounting portions 1220. One first mounting portion 1210 and one second mounting portion 1220 constitute a detection unit. There can be multiple second connecting ends 1320, which can be set one-to-one with the detection units. Each of the multiple first mounting portions 1210 can house a component to be tested, and each of the multiple second mounting portions 1220 can house a mating component. The component to be tested and the mating component are in one-to-one correspondence. Each detection unit is connected to a corresponding second connecting end 1320, ensuring communication with the component to be tested within the corresponding detection unit for detection. In this way, the photoelectric sensor detection fixture 10 can simultaneously perform aging characteristic detection on more components to be tested, resulting in higher detection efficiency. For example, the mounting member 120 can be approximately elongated, with multiple detection units arranged along the length of the mounting member 120. Each mounting member 120 can have 10 detection units.

[0031] For example, refer to Figure 1Multiple second connection terminals 1320 can be connected in series. Specifically, each conductive element 130 may include a first connection terminal 1310 and correspondingly connect multiple second connection terminals 1320. A first connection terminal 1310 and multiple second connection terminals 1320 connected in series form a conductive element 130 for communicating with the device under test (DUT). The multiple second connection terminals 1320 connected in series include multiple DUTs within a detection loop. If one DUT fails due to aging, the detection loop will break, and this failure will be transmitted to the display device via the display connector. This results in a simpler circuit structure for the photoelectric sensor detection fixture 10.

[0032] For example, refer to Figure 1 The photoelectric sensor detection fixture 10 may include multiple mounting parts 120, each of which can be connected to a main electrical component. Each mounting part 120 may be provided with a conductive part 130 and a display connector. One mounting part 120, one conductive part 130, and one display connector form an independent detection circuit with the main electrical component. Each display connector is connected to an external display. This configuration further increases the number of test objects that each photoelectric sensor detection fixture 10 can detect, especially in embodiments where there are multiple first mounting parts 1210 and multiple second mounting parts 1220, maximizing the detection capability of the photoelectric sensor detection fixture 10. In embodiments where a folding limiter 140 is provided, each mounting part 120 is provided with a corresponding folding limiter 140. Exemplarily, the multiple mounting parts 120 can be arranged along the length of the main body 110. There can be four mounting parts 120, and four conductive parts 130, four display connectors, and four external display connectors. All mating parts within the second mounting section 1220 of the four mounting parts 120 are connected to the main electrical components.

[0033] For example, refer to Figure 1 The display connector may include a lamp. Specifically, the display connector may include an LED lamp. When the circuit is connected, the lamp is lit; when the circuit is disconnected, i.e., the device under test is aging and cannot work properly, the lamp is off. In this way, it is more convenient to determine the status of the device under test by whether the lamp is lit or off, and the production cost of the photoelectric sensor detection fixture 10 is lower.

[0034] According to another aspect of this utility model, a photoelectric sensor detection system is also provided. This photoelectric sensor detection system may include a detection machine and any of the above-described photoelectric sensor detection fixtures 10. The detection machine is equipped with a display element, which is connected to a conductive element 130 via a display connector. Exemplarily, the detection machine can internally employ an FPGA (Field-Programmable Gate Array) for control and detection, resulting in a simple circuit and high speed. Since this photoelectric sensor detection fixture 10 adopts the technical solutions of any of the above embodiments, the photoelectric sensor detection system at least possesses the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated further here.

[0035] For example, refer to Figure 1 The photoelectric sensor detection fixture 10 can be multiple, and each mounting component 120 can be connected to at least one display component. That is, each mounting component 120 is connected to at least one display component via a display connector. Exemplarily, each mounting component 120 can be connected to only one display component. This arrangement of the photoelectric sensor detection system allows for the detection of a larger number of test pieces. Exemplarily, there can be four photoelectric sensor detection fixtures 10, each with four mounting components 120, and each mounting component 120 can contain ten first mounting parts 1210 and ten second mounting parts 1220. In this way, the photoelectric sensor detection system can simultaneously perform high-temperature aging tests on 160 test pieces. Of course, the number of photoelectric sensor detection fixtures 10 and / or mounting components 120 and / or first mounting parts 1210 in the photoelectric sensor detection system can be arbitrarily configured according to usage requirements. It is understandable that each photoelectric sensor detection fixture 10 in the photoelectric sensor detection system is relatively independent of each other and will not interfere with each other. They can be timed separately to meet the aging time requirements of different products.

[0036] The testing process can be specifically described as follows: Multiple test pieces are sequentially installed into their corresponding first mounting portions 1210. The mounting piece 120 is pushed so that the second connecting end 1320 contacts the pins of the test piece. The hinged limiting piece 140 pushes against the limiting mounting piece 120, ensuring full contact between the second connecting end 1320 and the pins of the test piece. The testing machine supplies power to the test pieces and mating parts through the main electrical components. If the power supply to the test pieces and mating parts is insufficient, the corresponding LED light will be off; if the power supply is sufficient, the corresponding LED light will be on. This ensures good power supply to all test pieces and mating parts (i.e., all LED lights remain on). The photoelectric sensor testing fixture 10 is placed in a high-temperature testing environment and kept powered on for 10 minutes (the required aging time). If an open circuit occurs in the testing circuit during the testing process, the corresponding LED light will be off. If all LED lights are on after the testing time, it indicates that all test pieces on the photoelectric sensor testing fixture 10 are good. This completes one aging test.
