Description

Technical Field

[0001] This invention relates to the field of lighting fixtures technology, and in particular to an automatic detection method and device for energy-saving lamps. Background Technology

[0002] In the production process of energy-saving lamps, during the semi-finished product stage, the quality of the lamp tubes needs to be tested, mainly by checking the vacuum level to determine the quality of the tubes. In the finished product stage, the brightness of the lamps needs to be tested to determine if they can light up normally. However, existing testing methods mainly rely on manual methods, involving energizing the product and observing the electrical phenomena to determine if the product quality is up to standard. Existing testing methods have the following drawbacks: First, manual testing is time-consuming, labor-intensive, cumbersome, and inefficient; second, wiring and energizing pose risks, such as electric shock; third, manual observation is physically demanding, causing eye fatigue, and the effectiveness and efficiency of manual judgment are low; fourth, the test results are limited, only showing brightness or vacuum level results, making comprehensive testing impossible. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the prior art, the present invention aims to solve the technical problem of providing an automatic detection method and device for energy-saving lamps, which solves the problems of low efficiency, easy error and safety hazards in the quality detection of energy-saving lamps in the prior art.

[0004] The technical solution adopted by this invention to solve its technical problem is an automatic detection method for energy-saving lamps, characterized by comprising the following steps:

[0005] S1. The energy-saving lamps to be tested are arranged horizontally and conveyed to the second conveying mechanism via the first conveyor belt and guide plate.

[0006] S2. The energy-saving lamp to be tested is changed from a horizontal to a vertical direction through a vertical pipe, and then rotated by the second conveyor belt;

[0007] S3. The infrared emitting diode outputs a signal to detect whether there is a blocking signal from the energy-saving lamp to be tested on the second transmission mechanism. If there is, the controller outputs a high-level signal and the signal generation circuit starts to work.

[0008] S4. Through the high-frequency oscillation circuit composed of the transistor and coil in the detection unit, the coil generates high-voltage induced current and releases a high-voltage AC signal to the energy-saving lamp under test.

[0009] S41. Detect the brightness of the energy-saving lamp under test using an illuminance sensor to determine whether the brightness of the energy-saving lamp under test is qualified.

[0010] S5. The high-voltage output is amplified by a circuit composed of a coil, a diode, and a capacitor, through the high-voltage induced current generated by the coil.

[0011] port;

[0012] S51. Detect the discharge intensity of the energy-saving lamp under test by using a current transformer to determine whether the vacuum degree of the energy-saving lamp under test is qualified.

[0013] S6. Based on the judgment results, if the brightness and vacuum degree are qualified, the energy-saving lamp to be tested is transferred to the qualified product stacking area; if the brightness and / or vacuum degree are unqualified, the energy-saving lamp to be tested is transferred to the unqualified product stacking area, thus completing the automatic test of the brightness and vacuum degree of the energy-saving lamp.

[0014] Furthermore, the non-conforming product stacking area in step S6 includes a brightness non-conforming area and a vacuum degree non-conforming area, wherein:

[0015] When the brightness of the energy-saving lamp under test is substandard, it is transferred to the substandard brightness area.

[0016] When the vacuum degree of the energy-saving lamp under test is unqualified, or both the brightness and vacuum degree are unqualified, it is transferred to the vacuum degree unqualified area.

[0017] Furthermore, the non-conforming product stacking area is equipped with an electromagnet and a baffle. When the energy-saving lamp under test is found to be unqualified in brightness or vacuum degree, the corresponding non-conforming product stacking area controller controls the electromagnet, and the electromagnet controls the baffle to block the qualified product stacking area and open the corresponding non-conforming product stacking area.

[0018] Furthermore, the baffle closes off the non-conforming product stacking area and opens the conforming product stacking area when the inspection work begins.

[0019] Furthermore, the controller determines whether the high-voltage induced current is outputting normally by whether there is a high-voltage output signal input; when the controller has no high-voltage output signal input, the controller outputs a signal, the audible and visual alarm sounds and stops the detection of the energy-saving lamp under test.

[0020] In a second aspect, the present invention provides an automatic detection device for energy-saving lamps, which enables the device to perform an automatic detection method for the brightness and vacuum level of energy-saving lamps.

[0021] Furthermore, the automatic detection device includes a first conveying mechanism and a second conveying structure arranged at different heights in space, and utilizes the height difference to convey the energy-saving lamp to be tested.

[0022] Furthermore, the second transmission mechanism is equipped with a sealed, opaque detection space for detecting the brightness and vacuum level of the energy-saving lamp under test.

[0023] Furthermore, the detection space is equipped with coils, wherein the first coil has an adjustable number of turns for adjusting the detection voltage; the third coil and the fourth coil are connected to external terminals for replacement when the detection space coil fails.

[0024] Furthermore, the detection space is equipped with a signal generation circuit and a control circuit. The signal generation circuit is located at the exit of the detection space and is connected to the third coil, the high-voltage output port, and the infrared emitting diode. The control circuit is located at the entrance of the detection space and is connected to the illuminance sensor and the infrared receiving diode.

[0025] Furthermore, the second conveying mechanism also includes a stationary second first conveyor belt and a rotating second second conveyor belt. The second first conveyor belt is used to fix the energy-saving lamp under test; the second second conveyor belt is used to drive the energy-saving lamp under test to rotate through friction.

[0026] Compared with the prior art, the present invention has at least the following beneficial effects:

[0027] (1) The automatic detection method and detection device for energy-saving lamps described in this invention detects the brightness of the energy-saving lamp under test by an illuminance sensor and detects the discharge intensity of the energy-saving lamp under test by a current transformer, and determines the vacuum degree of the energy-saving lamp under test to be qualified. Compared with the existing method of detecting lamps by connecting external wires, it is more convenient and safer to operate.

[0028] (2) The energy-saving lamp under test is conveyed by the conveyor mechanism to realize the automated continuous detection of the energy-saving lamp under test, and the energy-saving lamp under test is rotated by the friction of the conveyor belt, so as to detect it in all directions without dead angles, which improves the detection efficiency and saves labor costs.

[0029] (3) Set up automatic zoning of test results. The energy-saving lamps to be tested are divided into qualified product stacking area, brightness unqualified area and vacuum degree unqualified area. This makes it easier to process energy-saving lamps with different results by zoning and improves the efficiency of subsequent processing.

[0030] (4) The controller is set to judge whether the detection device is working properly by outputting a high voltage output signal to avoid misjudgment. When there is no high voltage output signal, the controller outputs a signal, the sound and light alarm emits an alarm signal, and at the same time controls the conveyor belt unit to stop, so as to avoid errors in the detection of the energy-saving lamp under test.

[0037] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments. Example

[0038] like Figure 1 As shown, the present invention provides an automatic detection method for energy-saving lamps, characterized by comprising the following steps:

[0039] S1. The energy-saving lamps to be tested are arranged horizontally and conveyed to the second conveying mechanism via the first conveyor belt and guide plate.

[0040] S2. The energy-saving lamp to be tested is changed from a horizontal to a vertical direction through a vertical pipe, and then rotated by the second conveyor belt;

[0041] S3. The infrared emitting diode outputs a signal to detect whether there is a blocking signal from the energy-saving lamp to be tested on the second transmission mechanism. If there is, the controller outputs a high-level signal and the signal generation circuit starts to work.

[0042] S4. Through the high-frequency oscillation circuit composed of the transistor and coil in the detection unit, the coil generates high-voltage induced current and releases a high-voltage AC signal to the energy-saving lamp under test.

[0043] S41. Detect the brightness of the energy-saving lamp under test using an illuminance sensor to determine whether the brightness of the energy-saving lamp under test is qualified.

[0044] S5. The high-voltage output is amplified by a circuit composed of a coil, a diode, and a capacitor, through the high-voltage induced current generated by the coil.

[0045] port;

[0046] S51. Detect the discharge intensity of the energy-saving lamp under test by using a current transformer to determine whether the vacuum degree of the energy-saving lamp under test is qualified.

[0047] S6. Based on the judgment results, if the brightness and vacuum degree are qualified, the energy-saving lamp to be tested is transferred to the qualified product stacking area; if the brightness and / or vacuum degree are unqualified, the energy-saving lamp to be tested is transferred to the unqualified product stacking area, thus completing the automatic test of the brightness and vacuum degree of the energy-saving lamp.

[0048] The energy-saving lamps under test are arranged horizontally along the first conveyor belt and guide plate, maintaining an appropriate distance. The guide plate's allowable width is equal to the width of the energy-saving lamps under test, ensuring they are arranged sequentially. The second conveyor belt, formed by a downward slope, creates a gradient from horizontal to vertical, ensuring the lamps' power-on terminals are securely clamped and prevent them from falling off. Energy-saving lamp testing is performed on the second conveyor mechanism. An infrared emitting diode outputs a signal on this mechanism to detect the presence of the energy-saving lamps. When a lamp is present, it blocks the infrared emitting diode's signal, preventing the infrared receiving diode from receiving the signal. This causes the controller to output a high-level signal, activating the signal generation circuit. A high-frequency oscillation circuit, consisting of transistor VT3 and coils L1 and L2, generates a high-voltage induced current at the terminals of coils L3 and L4, which the energy-saving lamps under test receive. After the high-voltage AC signal generated by coils L3 and L4 is received, if the energy-saving lamp under test is of qualified quality, it will emit light. The illuminance sensor PRO receives the brightness signal of the lamp under test, thereby judging the brightness of the energy-saving lamp under test. At the same time, the high-voltage induced current in coils L3 and L4 is further amplified to the high-voltage output terminal through the circuit composed of diodes VD6, VD7, VD8 and capacitors C3, C4, and C5 to test the vacuum degree of the energy-saving lamp under test. If the vacuum degree of the energy-saving lamp is unqualified, the high-voltage output terminal will discharge the energy-saving lamp. The discharge intensity can be detected by the current transformer TA1. According to the judgment result, if the brightness and vacuum degree are qualified, the energy-saving lamp under test is transferred to the qualified product stacking area; if the brightness and vacuum degree are unqualified, the energy-saving lamp under test is transferred to the unqualified product stacking area, thus completing the automatic test of the brightness and vacuum degree of the energy-saving lamp. Therefore, there is no need to power on the product or manually observe the power-on phenomenon to test the quality of the energy-saving lamp under test, improving the testing efficiency and making the testing operation more convenient and safer.

[0049] like Figure 2 and Figure 3 As shown, considering that different quality problems detected in the energy-saving lamps cannot be distinguished, manual repeated screening is required, reducing work efficiency. Optionally, the non-conforming product stacking area in step S6 includes the area with unqualified brightness and the area with unqualified vacuum degree, wherein:

[0050] When the brightness of the energy-saving lamp under test is substandard, it is transferred to the substandard brightness area.

[0051] When the vacuum degree of the energy-saving lamp under test is unqualified, or both the brightness and vacuum degree are unqualified, it is transferred to the vacuum degree unqualified area.

[0052] Optionally, the non-conforming product stacking area is equipped with an electromagnet and a baffle. When the energy-saving lamp under test is found to be unqualified in brightness or vacuum degree, the corresponding non-conforming product stacking area controller controls the electromagnet, and the electromagnet controls the baffle to block the qualified product stacking area and open the corresponding non-conforming product stacking area.

[0053] Optionally, the baffle can be used to close off the non-conforming product storage area and open the qualified product storage area at the start of the inspection process.

[0054] At the start of the testing process, baffles close off the areas for unqualified brightness and unqualified vacuum, leaving only the area for qualified products open. When the brightness of the energy-saving lamp under test is unqualified, the controller controls electromagnet YT1 to receive power, the illuminance sensor PRO outputs a low level, and electromagnet TY1 drives the first baffle, blocking the area for qualified products and opening the area for unqualified brightness. The energy-saving lamps under test that fail the brightness test are then transferred to the unqualified brightness area. When the vacuum of the energy-saving lamp under test is unqualified, the controller controls electromagnet YT2 to receive power, the current sensor TA1 outputs current, and electromagnet TY2 drives the second baffle, blocking the area for qualified products and opening the area for unqualified vacuum. The energy-saving lamps under test that fail the vacuum test are then transferred to the unqualified vacuum area. Energy-saving lamps that fail both brightness and vacuum tests are also transferred to the unqualified vacuum area. This facilitates the separate processing of energy-saving lamps with different results, improving subsequent processing efficiency.

[0055] like Figures 4-6 As shown, optionally, the controller determines whether the high-voltage induced current is output normally by whether there is a high-voltage output signal input; when the controller has no high-voltage output signal input, the controller outputs a signal, the audible and visual alarm sounds and stops the detection of the energy-saving lamp under test.

[0056] The controller determines whether the signal generation circuit is working properly by using the high-voltage output signal. When there is no high-voltage output signal input, the controller outputs a signal, the audible and visual alarm is powered on, and an alarm signal is issued. At the same time, the motor control unit controls the conveyor belt unit to stop running to avoid misjudgment. If the lack of voltage in the detection device is mistakenly identified as a problem with the quality of the energy-saving lamp under test, it will cause errors in the detection of the energy-saving lamp under test.

[0057] The entire detection method's circuit mainly consists of a power supply circuit, a high-voltage output circuit, and an infrared output circuit. Specifically, the power supply circuit comprises capacitors C1 and C2, resistor R3, diodes VD1, VD2, VD3, and VD4, and a Zener diode VD5; this circuit converts the 220V AC mains voltage into 5V DC voltage for use by related circuits. The high-voltage output circuit consists of transistor VT3, resistor R4, coils L1, L2, L3, and L4, diodes VD6, VD7, and VD8, and capacitors C3, C4, and C5. The signal generation circuit also includes an infrared emitting diode VT2 and a current sensor TA1. Capacitors C6 and C7 form a voltage divider circuit, and the output voltage is used for signal detection.

[0058] like Figure 2 and Figure 3 In another embodiment of the present invention, an automatic energy-saving lamp detection device is also provided, which enables the device to perform an automatic energy-saving lamp detection method. Optionally, the automatic detection device includes a first conveying mechanism and a second conveying structure that are arranged at different heights in space, and uses the height difference to convey the energy-saving lamp to be tested.

[0059] Optionally, the second transmission mechanism is equipped with a sealed, opaque detection space for detecting the brightness and vacuum level of the energy-saving lamp under test.

[0060] The test should be conducted in a sealed, opaque testing space to prevent interference from external light sources or other factors that could affect the test results.

[0061] Optionally, the detection space is equipped with coils, wherein the number of turns of the first coil is adjustable for adjusting the detection voltage; the third and fourth coils are connected to external terminals for replacement when the detection space coil fails.

[0062] Since the test parameters for different models and specifications of energy-saving lamps may vary, the first coil can be adjusted so that the output voltage can meet the test requirements. The third and fourth coils are backups. If any coil fails, it can be short-circuited through an external terminal to improve the reliability of the test.

[0063] like Figure 4 As shown, optionally, a signal generation circuit and a control circuit are provided in the detection space. The signal generation circuit is located at the exit of the detection space and is connected to the third coil, the high voltage output port and the infrared emitting diode. The control circuit is located at the entrance of the detection space and is connected to the illuminance sensor and the infrared receiving diode.

[0064] All detection units are located within the detection space. The energy-saving lamp under test enters from the entrance of the detection space for detection and exits from the exit. At the exit of the detection space, it is connected to the third coil, the high-voltage output port, and the infrared emitting diode. The high-voltage output port outputs high voltage to determine whether the generating circuit is working properly. At the entrance of the detection space, it is connected to the illuminance sensor PRO and the infrared receiving diode. The infrared receiving diode receives the infrared signal from the infrared emitting diode. When the infrared signal is blocked, it indicates that there is an energy-saving lamp under test on the second transmission mechanism; otherwise, there is no lamp, and the circuit does not operate. The energy-saving lamp under test is automatically detected by the illuminance sensor PRO through the high-voltage output of the high-voltage output port.

[0065] Optionally, the second conveying mechanism further includes a stationary second first conveyor belt and a rotating second second conveyor belt. The second first conveyor belt is used to fix the energy-saving lamp under test; the second second conveyor belt is used to drive the energy-saving lamp under test to rotate through friction.

[0066] In the second conveying mechanism, the second conveyor belt is stationary to fix the energy-saving lamp under test and prevent it from slipping and falling. The second conveyor belt drives the energy-saving lamp under test to rotate through friction, which allows the energy-saving lamp under test to be tested from all directions and improves the accuracy of the test.

[0067] In summary, the automatic detection method and device for energy-saving lamps of the present invention utilizes a high-frequency oscillation circuit composed of a transistor and a coil in the detection unit. The coil generates a high-voltage induced current, releasing a high-voltage AC signal to the energy-saving lamp under test. Based on the brightness result detected by the illuminance sensor, the brightness of the energy-saving lamp under test is determined to be qualified. The high-voltage output port is amplified by a circuit composed of the high-voltage induced current generated by the coil, a diode, and a capacitor. Based on the discharge intensity result detected by the current transformer, the vacuum degree of the energy-saving lamp under test is determined to be qualified. Then, based on different detection results, the energy-saving lamp under test is transferred to different areas, enabling the energy-saving lamp under test to automatically complete the brightness and vacuum degree quality detection without power. This makes the operation more convenient and safer, and improves the detection efficiency.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
