Description

Technical Field

[0001] The present invention relates to the field of infrared emitting tubes, and in particular to a detection method and a detection device for infrared emitting tubes. Background Art

[0002] The appearance of an ordinary infrared emitting tube is similar to that of a general visible light LED, but it emits infrared rays. Its tube voltage generally drops by about 1.4V, and its operating current is generally less than 20mA. In order to adapt to different operating voltages, a current-limiting resistor is often connected in series in the circuit. Due to its high power, the infrared emitting tube is also used to replace lasers in fiber optic communications and printers. Among them, LEDs are used for short-distance fiber optic communication transmission and reception in buildings. At present, when infrared emitting tubes are produced and prepared, it is usually necessary to use testing equipment to conduct power-on testing on their positive and negative pins to determine the quality of the infrared emitting tube. At this time, the infrared emitting tube needs to be plugged in and out, and the position of the infrared emitting tube needs to be adjusted to test the positive and negative pins respectively. The operation is too complicated, and the existing testing equipment cannot detect the service life of the infrared emitting tube. Therefore, there are certain disadvantages in use.

[0003] In view of the problem that the quality of infrared emitting tubes usually needs to be tested during production and preparation, the existing testing method requires plugging and unplugging the pins of the infrared emitting tubes, and the existing testing equipment cannot detect the service life of the infrared emitting tubes, we propose a testing method and testing device for infrared emitting tubes. Summary of the Invention

[0004] The present invention proposes a detection method and detection device for infrared emitting tubes, which solve the problem that infrared emitting tubes usually need to be tested for their quality during production and preparation. The existing detection method requires plugging and unplugging the pins of the infrared emitting tubes, and the existing detection equipment cannot detect the service life of the infrared emitting tubes.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A detection device for an infrared emitting tube includes a detection box, wherein electrode connectors are symmetrically arranged on the top of the detection box, and two groups of electrode connectors are arranged in a height shape. An infrared emitting tube body is arranged on the top of the detection box, and the pins at the bottom of the infrared emitting tube body pass through the two groups of electrode connectors and extend into the interior thereof. A detection mechanism is symmetrically arranged inside the detection box.

[0007] Preferably, a rubber ring is fixedly installed on the top of the electrode connector, the rubber ring is ring-shaped, and the rubber ring is made of elastic material. The rubber ring is sleeved with the pin of the infrared emitting tube body, and a support plate is symmetrically provided on the top of the detection box, and the support plate is bent. A guard plate is provided on one side of the support plate, the guard plate is arc-shaped, and the guard plate is sleeved with the infrared emitting tube body.

[0008] Preferably, the inner wall of the electrode connector is an electrode connecting piece, and the upper group of electrode connectors is connected to the negative electrode pin of the infrared emitting tube body.

[0009] Preferably, the detection mechanism includes a connecting circuit, a detection component, a control component and a power supply. The connecting circuit is provided in two groups, and one end thereof is respectively connected to the bottom circuits of the two groups of electrode connectors.

[0010] Preferably, the other end of the two groups of connecting circuits is connected to a detection component, a control component is provided on the top of the detection component, and the control component is wirelessly connected to the detection component, a power supply is provided on the side of the detection component away from the electrode connector, and the detection component is connected to the power supply through the connecting circuit.

[0011] Preferably, the detection component includes a data transmission module, a measurement module and a circuit module, and the circuit module includes a first operational amplifier circuit and a second operational amplifier circuit. The measurement module is used to measure the resistance of the pins of the infrared emitting tube body.

[0012] Preferably, the control component includes a judgment module, an opening and closing module, a processor, a storage, a recording module and a data receiving module. The judgment module is used to judge the quality and life of the infrared emitting tube body, the opening and closing module is electrically connected to the detection component, the storage is used to record the detection data, and the data receiving module is wirelessly connected to the data transmission module.

[0013] A detection method for an infrared emitting tube comprises the following steps:

[0014] S1: First, take out the device and place it in an appropriate position. At this time, take out the infrared emitting tube body to be tested and place it between the two sets of protective plates symmetrically arranged on the top of the detection box. At the same time, make sure that the positive and negative pins at the bottom of the infrared emitting tube body pass through the rubber ring and extend to the inside of the electrode connector, ensuring that the shorter set of pins at the bottom of the infrared emitting tube body are connected to the higher set of electrode connectors;

[0015] S2: At this time, a group of power supplies are started, and the detection component is closed through the opening and closing module set in the control component, so that the power supply forms a path with the electrode connector through the connecting circuit, thereby energizing a group of pins of the infrared emitting tube body through the electrode connector, and then judging the quality of the group of pins;

[0016] S3: At this time, the power supply described in the above step S2 is turned off, and another set of power supplies is started. The detection component is turned off by the opening and closing module provided in the control component matched with the other set of power supplies, so that the power supply forms a path with the electrode connector through the connecting circuit, thereby energizing the other set of pins of the infrared emitting tube body through the electrode connector, and then judging the quality of the other set of pins;

[0017] S4: At this time, a detection component wirelessly connected to the detection component is started through an on-off module provided in a group of control components, and a first operational amplifier circuit provided in a circuit module provided in the detection component is connected. The first operational amplifier circuit cooperates with the connection circuit to connect with the two groups of electrode connectors. At this time, the resistance of the infrared emitting tube body is measured in cooperation with a measurement module provided in the detection component. At the same time, the resistance value is transmitted to the interior of the control component through a data transmission module provided in the detection component. At the same time, the resistance value is recorded by a recording module provided in the control component, and the resistance value is marked as a first resistance value.

[0018] S5: Repeat the above step S4, connect the first operational amplifier circuit provided in the circuit module provided in the detection component, and connect the second operational amplifier circuit in conjunction with the connection circuit to the two groups of electrode connectors. At this time, cooperate with the measurement module provided in the detection component to measure the resistance of the infrared emitting tube body, and transmit the resistance value to the control component through the data transmission module provided in the detection component. At the same time, the recording module provided in the control component records the resistance value and marks the resistance value as the second resistance value.

[0019] S6: The processor provided in the control component cooperates with the recording module and the judgment module to calculate the difference between the two sets of resistance values recorded in the recording module, and compares the obtained resistance difference with the set resistance value. If the resistance difference is less than the set resistance value, the life of the infrared emitting tube body in the current direction is zero, otherwise the life is not exhausted;

[0020] S7: At this time, the detection component wirelessly connected to the detection component is activated by the opening and closing module inside the control component set inside the other detection mechanism, and the above step S4 is repeated to record the first resistance value in this current direction and record it through the recording module;

[0021] S8: Repeat the above step S5, detect the second resistance value of the infrared emitting tube body under this current direction through the second operational amplifier circuit, and record it through the recording module;

[0022] S9: The processor inside the control component set inside another set of detection mechanisms cooperates with the recording module and the judgment module to calculate the difference between the two sets of resistance values recorded inside the recording module, and compare the obtained resistance difference with the set resistance value. If it is less than the set resistance value, the life of the infrared emitting tube body under the current direction is zero, otherwise the life is not exhausted.

[0023] Preferably, the current supply directions of the two power supply groups described in the above step S1 and step S2 are opposite.

[0024] Preferably, the recording module in the above step S6 is electrically connected to the storage.

[0025] The beneficial effects of the present invention are:

[0026] 1. The detection component set inside the device performs resistance detection on the infrared emitting tube body through the first operational amplifier circuit and the second operational amplifier circuit respectively, and judges whether the infrared emitting tube body has a life span by judging the relationship between the difference between the two groups of resistances and the preset resistance value. At the same time, the two groups of detection mechanisms are used to detect the positive and negative pins of the infrared emitting tube body respectively.

[0027] 2. The two sets of detection mechanisms symmetrically arranged inside the device supply power to the connecting circuit through the power supply. At the same time, the detection component is closed by the opening and closing module set inside the control component, so that a path is formed between the connecting circuit and the power supply. The positive and negative pins of the infrared emitting tube are powered on and tested in turn by the two sets of detection mechanisms from the beginning to judge the quality of the infrared emitting tube.

[0028] 3. The electrode connector set inside the device is evenly filled with electrode sheets and is funnel-shaped, so it can adapt to pins of different sizes. At the same time, the rubber ring set on the top of the electrode connector facilitates the fixation and limitation of the pins. Since the pins are made of elastic material, they can adapt to pins of different sizes. At the same time, the support plate and guard plate symmetrically set on the top of the test box can prevent the infrared emitting tube from being excessively tilted, thereby affecting the test results.

[0029] To sum up, the device facilitates the detection of the resistance value of the positive and negative pins of the infrared emitting tube through the circuit module set inside the detection component, and then compares the resistance value difference at the detection point with the set resistance value to judge the service life of the infrared emitting tube body. At the same time, the detection component is closed by the opening and closing module, and the two sets of symmetrically arranged detection mechanisms are used to facilitate the quality inspection of the positive and negative pins of the infrared emitting tube body, avoiding plugging and unplugging operations. At the same time, the funnel-shaped electrode connector set inside the device can also adapt to pins of different models, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
