Description

Technical Field

[0001] The present invention relates to the technical field of brightness detection, and in particular to a brightness detection device and method for an LED lamp. Background Art

[0002] An LED lamp is an electroluminescent semiconductor chip, solidified with silver or white glue onto a bracket. Silver or gold wires are then used to connect the chip to a circuit board, and the surrounding area is sealed with epoxy resin to protect the internal core wires. The heart of the LED is a semiconductor wafer, attached to a bracket at one end, with one end connected to the cathode and the other to the positive terminal of a power supply. The entire wafer is encapsulated in epoxy resin. The production and processing of LED lamps involves a brightness testing process. The LED lamp is transported to a brightness testing instrument. After power is applied, the LED lamp illuminates the testing instrument. The light intensity is measured to determine if the LED lamp is qualified. If a problem occurs with the testing instrument, even if the measured light intensity is within the required range, the LED lamp still has a problem, resulting in a detection failure. Multiple testing instruments can be used to perform brightness testing on the LED lamp in turn. The test results of the problematic instrument will inevitably differ from those of the other normal instruments. This method not only completes the lamp testing process, but also allows the problematic instrument to be identified promptly based on the data discrepancies. To this end, the present invention provides a brightness testing device and method for LED lamps. Summary of the Invention

[0013] A method for detecting the brightness of an LED lamp comprises the following steps: Step 1: The conveyor frame transports the energized LED lamps one by one through each shade, and stops under each shade for a fixed time. During the stop, the light blocking box above descends to cover the LED lamps, and the LED lamps illuminate the luminance meter above. The luminance meter sends the detected light intensity data to the host terminal; Step 2: After the host terminal collects the single light intensity data, it controls the light blocking box to rise to the top, and the control assembly increases the number of light blocking box lifts collected by one. The LED lamp is then transported to the bottom of the next light shield for another light intensity test. This cycle is repeated to perform multiple light intensity tests on the LED lamp. Step 3: After the test is completed, if the test result data of the problematic luminance meter is different from the test result data of the other luminance meters, and the test result data of the other luminance meters are the same, the host terminal will control the control assembly above the problematic luminance meter to operate, so that the control assembly will be magnetically driven to directly drag the problematic luminance meter out of the test queue. At the same time, the number of light blocking box lifting and lowering times collected by the control assembly will be reset to zero. If the luminance meter has always been working normally, the control assembly will automatically trigger the power storage drive after the number of light blocking box lifting and lowering times collected is full, and the luminance meter with the end of life will be dragged out of the test queue. Step 4: After a luminance meter is dragged out of the detection queue, the replacement luminance meter will be pushed to the power connection position above the shutter, and the detection queue will resume normal operation.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention uses multiple luminance meters to continuously test the brightness of LED lamps. If a single luminance meter fails, the test results of the failed luminance meter will be different from the test results of multiple normal luminance meters. Therefore, while completing the brightness test, the present invention can also analyze whether any luminance meter in the test row has failed.

[0015] 2. If a luminance meter fails during operation, the magnetic attraction mechanism in the control assembly will be controlled and triggered. The subsequent drive will forcibly drag the luminance meter out of the detection queue and replace it with a new luminance meter. At the same time, the life counter mechanism in the control assembly will be reset. If the luminance meter works normally to the end and the count mechanism in the control assembly is full, the control assembly will also drag the aged luminance meter out of the detection queue and replace it with a new luminance meter to avoid potential problems caused by the aged luminance meter continuing to work.

The direction rod 25 slides through the through hole opened on the T-shaped vibration plate 26. The direction rod 25 is also fixed with an intercepting ring for limiting the moving range of the T-shaped vibration plate 26.

[0038] refer to Figure 7 It is understood that the pressure integration 16 includes a side frame 27 fixed on the concave rail shell 15, a side shaft 28 supported on the side frame 27, a long horizontal shaft 29 and a worm 31, a side gear 30 engaged with the helical teeth on the worm 31, a one-way bearing 32 fixed at one end of the worm 31, and a ring plate gear 33 fixed outside the one-way bearing 32. One end of the side shaft 28 is fixed to the middle of the side gear 30, and the other end is vertically transmitted to the side frame 27. The T-shaped vibration plate 26 is connected to the ring plate gear 33 by setting a row of teeth. The side shaft 28, the long horizontal shaft 29 and the worm 31 are respectively movably sleeved in different through holes opened on the side frame 27. The transmission is realized by setting two bevel gears at the junction of the side frame 27 and the side shaft 28.

[0039] refer to Figure 8 and Figure 9 It is understood that the light shielding device 5 includes a light blocking box 37 that is lifted and lowered to block light, a dark box 34 set on the top of the light blocking box 37, a concave support 36 fixedly connected between the dark box 34 and the cross rail 2, and a follower plate 35 fixed on the light blocking box 37. When the light blocking box 37 rises to the top, the follower plate 35 presses the T-shaped vibration plate 26. The dark box 34 includes a square box shell-shaped static box shell 38, two symmetrically distributed door panels 41 are set at the lower end of the static box shell 38, a door shaft 40 fixed to the edge of the door panel 41, and a pressure-generating mechanism that drives the door shaft 40 to rotate. Group 39, the light blocking box 37 is a square box shell with an opening at the bottom, the static box shell 38 slides through the square hole opened on the top shell of the light blocking box 37, and the top and bottom shells of the static box shell 38 are both provided with round holes for the luminance meter 6 to receive light, and the two door panels 41 cooperate to block the bottom round hole on the static box shell 38, the top of the concave support 36 is fixed on the static box shell 38, and when the light blocking box 37 drops to the bottom, the door panel 41 is controlled to swing by pressing the pressure group 39, and the concave support 36 also slides through the inner hole of the square tube fixed on the light blocking box 37, Figure 9The pressure-generating group 39 is a pressure-generating component in the prior art. The light-blocking box 37 presses down the pressure-generating group 39, driving the door shaft 40 to rotate, and then the two door panels 41 swing downward and apart. At this time, the light-blocking box 37 covers the LED lamp 4, and the LED lamp 4 is powered on to emit light. The light passes through the static box shell 38 and shines on the luminance meter 6. The luminance meter 6 detects the brightness of the light. The luminance meter 6 is a prior art instrument. Here, the light-blocking box 37 completely covers the LED lamp 4 before the door panel 41 is opened. Before opening, the light receiving port on the luminance meter 6 is in a dark environment sealed by the static box shell 38. This protects the light-sensitive element in the luminance meter 6, because the light-sensitive element is still exposed to light when it is not working, causing a photoelectric reaction. The light-sensitive element does not get a rest and will accelerate aging, thereby shortening the working time of the luminance meter 6.

[0040] The light blocking box 37 is externally connected to a lifting drive mechanism in the prior art, that is, the lifting drive mechanism is controlled by a host terminal in the prior art, thereby controlling the lifting and positioning of the light blocking box 37 .

An electromagnet 45 is set above each luminance meter 6 in the detection station. The electromagnet 45 and the luminance meter 6 are both set under the control of the host terminal. If the luminance meter 6 detects that there is a problem with the light intensity of the LED lamp 4, while the other multiple luminance meters 6 detect no problem, it means that the luminance meter 6 that has detected the problem has a problem itself and needs to be kicked out of the detection queue. The host terminal controls the electromagnet 45 corresponding to the luminance meter 6 with the problem. When power is turned on, the electromagnet 45 magnetically attracts the metal column 46, and then the L-shaped control plate 47 moves to drive the fixed shaft 49 to rotate, and then the swing plate 42 swings to drive the travel shaft 43 to rotate, and then the travel gear 44 rotates to drive the first straight rack 19 to directional translation, and the first straight rack 19 hooks the square plate frame 10, and one end edge of the square plate frame 10 is pulled out of the concave rail shell 15, and then the square plate frame 10 drives the problematic luminance meter 6 to translate, that is, the problematic luminance meter 6 is moved vertically out of the queue, and then a new luminance meter 6 is added for testing.

[0045] A method for detecting the brightness of an LED lamp comprises the following steps: Step 1: The transport carriage 3 transports the energized LED lamps 4 one by one through each shade 5, and stops under each shade 5 for a fixed time. During the stop, the light blocking box 37 above descends to cover the LED lamps 4, and the LED lamps 4 illuminate the luminance meter 6 above. The luminance meter 6 sends the detected light intensity data to the host terminal; Step 2: After the host terminal collects the single light intensity data, it controls the light blocking box 37 to rise to the top, and the control assembly 9 increases the number of times the light blocking box 37 is raised and lowered by one. The LED lamp 4 is then transported to the bottom of the next light shield 5 for another light intensity test. This cycle repeats, and the LED lamp 4 is subjected to multiple light intensity tests. Step 3: After the test is completed, if the test result data of the problematic luminance meter 6 is different from the test result data of the other luminance meters 6, and the test result data of the other luminance meters 6 are the same, the host terminal will control the control assembly 9 above the problematic luminance meter 6 to operate, so that the control assembly 9 performs magnetic attraction driving, directly drags the problematic luminance meter 6 out of the test queue, and at the same time, the number of times the light blocking box 37 is raised and lowered collected by the control assembly 9 is reset to zero. If the luminance meter 6 always works normally, the control assembly 9 will automatically trigger the power storage drive after the number of times the light blocking box 37 is raised and lowered collected is full, and the luminance meter 6 with the end of its life will be dragged out of the test queue; Step 4: After a luminance meter 6 is dragged out of the detection queue, the replacement idle luminance meter 6 will be pushed to the power connection position above the shutter 5, and the detection queue will resume normal operation.

[0046] The control assembly 9 has two mechanisms to pull the luminance meter 6 out of the detection queue. One is the magnetic drive under the active control of the host terminal, and the other is the power storage drive after the luminance meter 6 has worked a sufficient number of times. The luminance meter 6 is then automatically replaced to avoid the problem of detection errors caused by aging luminance meter 6.

[0047] The principle of the power storage drive is: each detection of the brightness meter 6 involves the lifting and lowering of the light blocking box 37 below, so the lifting and lowering times of the light blocking box 37 accumulate to the specified value, the brightness meter 6 will be dragged out of the power connection position by the control assembly 9, and then the replacement brightness meter 6 will be automatically added, the light blocking box 37, and the light blocking box 37 will press the follower plate 35 when it rises to the top, so the lifting of the light blocking box 37 causes the follower plate 35 to lift and lower, and then the lifting of the T-shaped vibration plate 26 drives the ring plate gear 33 to swing back and forth, and then causes the worm 31 to rotate intermittently in a directional manner through the one-way bearing 32, and then the side gear 30 slowly rotates to drive the side shaft 28, and then transmits the main gear 51 through the long horizontal shaft 29, and then drives the head shaft 53 to rotate through the double-control gear 63, and then the booster shaft The rotation of 59 causes the mainspring 60 to contract and store energy. During the process of the mainspring 60 storing energy, the brightness meter 6 is working continuously to detect the LED lamps 4 transported one by one below. The brightness meter 6 stops working and the light blocking box 37 stops rising and falling. Naturally, the subsequent transmission causes the mainspring 60 to stop storing energy. After the mainspring 60 stores energy to saturation, it continues to store energy, and the disk box 61 will break through the position of the hook spring 58. In this way, the mainspring 60 releases power to make the disk box 61 rotate quickly one circle, and the tail shaft 56 and the cam 57 rotate one circle synchronously. The cam 57 moves the pendulum plate 42 during one rotation. As mentioned in the previous magnetic drive, the swing of the pendulum plate 42 will eventually drag the square plate frame 10 out, that is, the brightness meter 6 that has reached the end of its life leaves the detection queue, and the detection station is specified as the area directly below the sunshade 5.

[0048] The control assembly 9 also has a reset mechanism. If the brightness meter 6 fails before the end of its normal life, the magnetic drive causes the brightness meter 6 to leave, which will cause the count in the power storage integration 21 to be reset. In this way, after the new brightness meter 6 is added, the count will start again, that is, the spring 60 will recharge the power. The reset process is that the spring 60 releases the previous power. Specifically, the magnetic drive causes the square plate frame 10 to move vertically out of the queue. During the removal process, the J-shaped spring 12 will hit the reciprocating plate 65 once, and the reciprocating plate 65 will move horizontally to drive the swimming seat 62. Figure 16 The double-control shaft 66 in the middle moves axially to the right, driving the double-control gear 63. The double-control gear 63 is separated from the main gear 51. Previously, the rotation and positioning of the boost shaft 59 were controlled by the long horizontal shaft 29. The long horizontal shaft 29 rotates and is positioned under the worm drive. The boost shaft 59 will not reverse. However, the double-control gear 63 is separated from the main gear 51, and the restraint from the long horizontal shaft 29 disappears. The power-accumulating spring 60 will reversely drive the boost shaft 59, and the boost shaft 59 will quickly reverse multiple turns until the power stored in the spring 60 is released. The double-control gear 63 and the main gear 51 are briefly separated, and the pressure in the spring 60 is released in the reverse direction, achieving the effect of resetting the count.
