Description

Technical Field

[0002] An LED lamp is a light source that uses semiconductor materials and emits light through current drive. Due to its advantages such as high efficiency, low energy consumption, and long lifespan, the LED lamp has become one of the widely used technologies in modern lighting. The hardness testing of LED lamps is usually to evaluate the tolerance of their outer shells, surfaces, and internal components under physical impact or pressure. Hardness testing is crucial for ensuring the safety and reliability of LED lamps during transportation, installation, and use.

[0003] The prior art document with the publication number CN109060569A provides a lamp board hardness detection device for the production of LED lighting lamps. By setting a lamp board positioning screw rod and a quick clamp, it can flexibly expand and contract and cooperate with the test needle fixing plate to accurately connect the LED lamp board to the test power supply, improving the stability and safety of the device. At the same time, different test needle fixing plates can be replaced to test LED lamp boards of different models, thereby improving the test efficiency and test quality of production.

[0023] As Figure 3 shown, a glass door 101 is rotatably connected at the opening of the testing box 1. A handle 102 is rotatably connected at the door frame of the glass door 101. The end of the handle 102 located inside the testing box 1 is in sliding contact with one side inner wall of the testing box 1. A positioning groove 103 is opened on the inner wall of the bottom end of the testing box 1.

[0024] As Figure 4 shown, a positioning plate 201 is fixedly connected to the lower surface of the waste box 2. The positioning plate 201 is movably inserted into the positioning groove 103. Two handlebars 202 are symmetrically and fixedly connected to the upper side inner wall of the waste box 2. The positioning groove 103 facilitates the positioning of the waste box 2 and is convenient for collecting the broken LED lamps 4.

[0025] As Figure 5 shown, a frustum 301 is in sliding contact with the top end of the LED lamp fixing sleeve 3. A plurality of clamping blocks 302 are slidably fitted on the inner walls of the four sides of the LED lamp fixing sleeve 3. The clamping blocks 302 are in movable contact with one end of the LED lamp 4. A tension spring A303 is fixedly connected to the clamping blocks 302. The other end of the tension spring A303 is fixedly connected to the top end of the LED lamp fixing sleeve 3. The top end of the clamping block 302 is in sliding contact with the inclined surface of the frustum 301. The bottom end of the clamping block 302 is provided with an inclined surface. When the pressure rod 503 rotates, the pressure rod 503 contacts and presses the frustum 301, causing the frustum 301 to move downward. At this time, the inclined surface of the frustum 301 will contact the top end of the clamping block 302, causing the lamp head of the LED lamp 4 to be released.

[0026] As Figure 6As shown in the figure, the transmission mechanism 5 includes a universal joint 501, which is rotatably connected to the inner wall of the test box 1. A one-way wheel 502 is fixedly connected to the bottom end of the universal joint 501, and a pressure rod 503 is fixedly connected to the top end of the universal joint 501. The other end of the pressure rod 503 is in sliding contact with the upper surface of the frustum 301. The transmission gear 702 on the moving seat 7 drives the universal joint 501 connected to the one-way wheel 502 to rotate, so that the universal joint 501 drives the connected pressure rod 503 to rotate.

[0027] As Figure 7 shown in the figure, the retracting and extending mechanism 6 includes an L-shaped rod 601, which is slidably and penetratingly fitted with the inner wall of the test box 1. The outer end of the L-shaped rod 601 is in movable contact with the bottom end of the glass door 101. A U-shaped rack 602 is fixedly connected to the inner end of the L-shaped rod 601. Two gears 603 are meshed and driven on both sides of the U-shaped rack 602. The gears 603 are rotatably connected to the inner wall of the test box 1. A connecting rod group 604 is fixedly connected to the gears 603 through a pin shaft. The other end of the connecting rod group 604 is rotatably connected to the moving seat 7. When the glass door 101 is closed, the glass door 101 contacts and presses the L-shaped rod 601, so that the L-shaped rod 601 drives the connected U-shaped rack 602 to move. At this time, the U-shaped rack 602 drives the connecting rod group 604 connected to the two gears 603 to rotate, so that the connecting rod group 604 drives the moving seat 7 to move under the LED lamp 4.

[0028] As Figure 7 shown in the figure, a spring 701 is fixedly connected to one side of the moving seat 7, and the other end of the spring 701 is fixedly connected to the inner wall of the test box 1. A plurality of transmission gears 702 are rotatably connected to the moving seat 7 in a linear structure. A tension spring B 703 is fixedly connected to the transmission gears 702, and the other end of the tension spring B 703 is fixedly connected to the moving seat 7. The transmission gears 702 are meshed and driven with the one-way wheel 502. The function of the tension spring B 703 enables the transmission gears 702 to drive normally when stressed in a specific direction, and slip when in the opposite direction, so as to realize the one-way transmission of the transmission gears 702.

[0029] As Figure 8 shown in the figure, a plurality of adjusting blocks 805 are arranged on the guide frame 803. A plurality of limiting shafts 806 are fixedly connected to one side of the adjusting blocks 805, and the outer walls of the limiting shafts 806 are in sliding contact with the outer wall of the guide frame 803.

[0030] A motor B807 is fixedly connected to the guide frame 803. The output end of the motor B807 is fixedly connected with an adjusting wheel 808. The adjusting wheel 808 is meshed and driven with the guide rack 804. An electric push rod 809 is fixedly connected to the guide frame 803. The output end of the electric push rod 809 is fixedly connected with a test head 810. The test head 810 is in movable contact with the outer wall of the LED lamp 4. The motor A802 drives the guide frame 803 connected to the rotating rod 801 to rotate to a suitable angle, and the motor B807 drives the connected adjusting wheel 808 to rotate, so that the adjusting wheel 808 meshes with the guide rack 804, which will drive the adjusting block 805 to move to a suitable position on the guide frame 803. Then, the electric push rod 809 drives the connected test head 810 to move, so that the test head 810 can contact and press the outer wall of the LED lamp 4. At this time, the piezoelectric sensor on the test head 810 can sense the pressure applied to the surface and convert the pressure into an electrical signal until the outer wall of the LED lamp 4 is broken to complete the test.

[0031] By setting the hardness testing mechanism 8 and using the guide frame 803 adapted to the shape of the spherical LED lamp 4, the hardness test of the spherical LED lamp 4 can be realized. At the same time, by setting a plurality of test heads 810 that can move on the self-rotating guide frame 803, the hardness test can be carried out at different positions of the LED lamp 4 according to needs, which can not only improve the test accuracy and efficiency, but also ensure the comprehensiveness of the test, reduce manual intervention, and improve the reliability and analysis ability of data.

[0032] Working principle: When the hardness test of the LED lamp 4 is required, first insert the lamp head of the LED lamp 4 into the LED lamp fixing sleeve 3. Then, under the action of the tension spring A303, the clamping block 302 clamps and fixes the LED lamp 4. Then, after closing the glass door 101 by holding the handle 102, turn the handle 102 so that one end of the handle 102 is inserted into the test box 1 for fixing; When the glass door 101 is closed, the glass door 101 will contact and press the L-shaped rod 601, so that the L-shaped rod 601 drives the connected U-shaped rack 602 to move. At this time, the U-shaped rack 602 will drive the connecting rod group 604 connected to the two gears 603 to rotate, so that the connecting rod group 604 drives the moving seat 7 to move below the LED lamp 4; Then, according to the test requirements, a certain number of adjusting blocks 805 are sleeved on the guide frame 803. Then, the guide frame 803 connected to the rotating rod 801 is driven by the motor A802 to rotate to an appropriate angle. And the adjusting wheel 808 connected to the motor B807 is driven to rotate, so that the adjusting wheel 808 meshes with the guide rack 804, which will drive the adjusting block 805 to move to an appropriate position on the guide frame 803. Then, the test head 810 connected to the electric push rod 809 is driven to move, so that the test head 810 can contact and press the outer wall of the LED lamp 4. At this time, the piezoelectric sensor on the test head 810 can sense the pressure applied on the surface and convert the pressure into an electrical signal until the outer wall of the LED lamp 4 is broken to complete the test. Then, the guide frame 803 is driven by the motor A802 to rotate to an appropriate angle; Then when the glass door 101 is opened, the L-shaped rod 601 is not restricted. At this time, under the action of the spring 701, the moving seat 7 will be driven to reset. At the same time, the transmission gear 702 on the moving seat 7 will drive the universal joint 501 connected to the one-way wheel 502 to rotate, so that the universal joint 501 drives the connecting pressure rod 503 to rotate, making the pressure rod 503 contact and press the conical platform 301, causing the conical platform 301 to move downward. At this time, the inclined surface of the conical platform 301 will contact the top of the clamping block 302, so that the lamp head of the LED lamp 4 is loosened. Then, the lamp head of the LED lamp 4 will fall into the waste box 2 for collection. Then, the waste box 2 is taken out of the test box 1 through the handle 202, and the broken LED lamp 4 is poured out. Then, the positioning disk 201 at the bottom of the waste box 2 is inserted into the positioning groove 103 for fixation.
