Description

Technical Field

[0001] This application relates to the field of light bulb manufacturing, and more particularly to a light bulb testing device. Background Technology

[0002] In the manufacturing process of lighting products, the reliability and lifespan of finished light bulbs are core indicators for measuring their quality. To screen out products that fail early and evaluate their long-term performance, frequent switching (switching cycle test) and continuous heating (high temperature load test) are two indispensable and extremely critical factory testing procedures. Frequent switching test simulates the scenario of users repeatedly switching the bulb on and off in daily use, and is used to test the shock resistance of the bulb's internal drive power supply, the fatigue resistance of the filament, and the reliability of the connecting components. On the other hand, continuous heating test involves lighting the bulb at a higher power for an extended period of time, allowing it to reach and maintain its operating temperature, in order to evaluate the bulb's heat dissipation design, the heat resistance of the materials, and the light decay and color drift under high-temperature environments. This is an important means of predicting product lifespan and stability. However, current bulb testing is all done manually, which is inefficient and inconvenient. Utility Model Content

[0003] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes a light bulb testing device, which can solve the technical problem that current light bulb testing is all done manually, which is inefficient and causes inconvenience in the testing process.

[0004] A light bulb detection device according to an embodiment of this application includes: frame; A feeding mechanism, located at the top of the frame, is used to feed light bulbs. A conveying mechanism, located inside the frame, is used to receive the light bulbs from the feeding mechanism and to convey the energized light bulbs. A heating mechanism, located at the bottom of the frame, is used to heat the bulbs during transport; The lamp inspection mechanism, located at the top of the frame, is used to inspect the lamps after they have been heated. The coding mechanism, located on the top of the frame, is used to code the light bulbs after light detection; The discharging mechanism, located at the top of the frame, is used to discharge the printed bulbs. The conveying mechanism includes two drive chains, multiple conveyor plates, multiple lamp holders, a connecting frame, an inner electrode plate, multiple contact seats, and multiple contact electrode feet. The two drive chains are internally connected to the frame. The multiple conveyor plates are located on the outer edges of the two drive chains and are evenly spaced. The multiple lamp holders are located on one side of the conveyor plates. The connecting frame is located inside the frame. There are two inner electrode plates, each located on one side of the connecting frame. The connecting frame and the inner electrode plates are located within the inner ring of the drive chains. The inner electrode plates are electrically connected to an external circuit. The multiple contact seats are located on the other side of the multiple conveyor plates. The multiple contact electrode feet are located on one side of the multiple contact seats. The contact electrode feet are electrically connected to the interior of adjacent lamp holders and slide with adjacent inner electrode plates, thus electrically connecting the contact electrode feet to the adjacent inner electrode plates. The bulb testing device according to the embodiments of this application has at least the following beneficial effects: the feeding mechanism places the bulb to be tested onto the lamp holder of the conveying mechanism, ensuring the continuity of the testing process. The conveying mechanism adopts a double-drive chain drive, which drives the equally spaced conveying plates to move. Each conveying plate is equipped with a lamp holder and contact electrode feet. When the conveying starts, the bulb is first conveyed to the bottom of the conveying mechanism (usually, the lamp holder has a snap-fit ​​structure inside, so that the bulb is inserted into the lamp holder and snapped in place, preventing the bulb from falling out when inverted). At this time, the contact electrode feet of the conveying plate form a sliding contact with the inner plate of the fixed electrode, so that the bulb is energized. By controlling the on / off timing of the inner plate of the electrode through the existing control system, the bulb can be frequently switched on and off during the conveying process, simulating daily use. During the current surge test, when the bulb is conveyed to the top of the conveying mechanism, the contact electrode feet maintain continuous contact with the inner electrode plate, and the bulb enters a constant-on state. At this time, the heating mechanism heats the bulb from below in a directional manner, keeping it in a high-temperature working state under over-rated power, testing the bulb's heat dissipation capacity and material heat resistance. Subsequently, the lamp inspection mechanism checks whether the heated bulb can still light up normally, determining whether the bulb meets the standard. The marking mechanism marks the lit bulbs with a qualified mark according to the test results, while marking the unlit bulbs with a unqualified mark. Finally, the unloading mechanism unloads the qualified and unqualified products separately. This fully automated testing replaces traditional manual operation, avoiding human error and rhythm fluctuations. The testing process is continuous and accurate, significantly shortening the testing time for a single batch of products.

[0022] Reference Figures 1 to 10 A bulb detection device, comprising: a frame 100; The feeding mechanism 300 is located on the top of the frame 100 and is used to feed light bulbs. The conveying mechanism 200, located inside the frame 100, is used to receive the light bulbs from the feeding mechanism 300 and to convey the energized light bulbs. A heating mechanism 400, located at the bottom of the frame 100, is used to heat the bulbs during transport. The lamp inspection mechanism 500 is located on the top of the frame 100 and is used to inspect the lamps after they have been heated. The coding mechanism 600 is located on the top of the frame 100 and is used to code the light bulbs after light detection. The discharge mechanism 700 is located on the top of the frame 100 and is used to discharge the printed bulbs. The conveying mechanism 200 includes two drive chains 211, multiple conveyor plates 220, multiple lamp holders 221, a connecting frame 230, an inner electrode plate 240, multiple contact seats 222, and multiple contact electrode feet 223. The two drive chains 211 are internally connected to the frame 100. The multiple conveyor plates 220 are located on the outer edges of the two drive chains 211 and are evenly spaced. The multiple lamp holders 221 are located on one side of the conveyor plates 220. The connecting frame 230 is located inside the frame 100. There are two inner electrode plates 240. Plates 240 are respectively disposed on both sides of the connecting frame 230. The connecting frame 230 and the inner electrode plate 240 are located in the inner ring of the transmission chain 211. The inner electrode plate 240 is electrically connected to the external circuit. Multiple contact seats 222 are respectively disposed on the other side of multiple conveying plates 220. Multiple contact electrode feet 223 are respectively disposed on one side of multiple contact seats 222. The contact electrode feet 223 are electrically connected to the interior of the adjacent lamp holder 221. The contact electrode feet 223 slide and cooperate with the adjacent inner electrode plate 240, so that the contact electrode feet 223 are electrically connected to the adjacent inner electrode plate 240. Understandably, the feeding mechanism 300 places the bulb to be tested onto the lamp holder 221 of the conveying mechanism 200 to ensure the continuity of the testing process. The conveying mechanism 200 uses a double-drive chain 211 to drive the equally spaced conveyor plates 220. Each conveyor plate 220 is equipped with a lamp holder 221 and contact electrode feet 223. When conveying begins, the bulb is first conveyed to the bottom of the conveying mechanism 200 (usually, the lamp holder 221 has a snap-fit ​​structure inside, allowing the bulb to be inserted into the lamp holder 221 for snap-fit, preventing the bulb from falling out when inverted). At this time, the contact electrode feet 223 of the conveying plate 220 form sliding contact with the fixed electrode inner plate 240, energizing the bulb. By controlling the on / off sequence of the electrode inner plate 240 through the existing control system, frequent switching cycle tests of the bulb can be performed during the conveying process to simulate... During daily use, when the bulb is conveyed to the top of the conveying mechanism 200, the contact electrode foot 223 maintains continuous contact with the inner electrode plate 240, and the bulb enters a constant-on state. At this time, the heating mechanism 400 heats the bulb from below in a directional manner, keeping it in a high-temperature working state under over-rated power, testing the bulb's heat dissipation capacity and material heat resistance. Subsequently, the lamp inspection mechanism 500 checks whether the heated bulb can still light up normally, determining whether the bulb meets the standard. The marking mechanism 600 marks the lit bulbs with a qualified mark according to the test results, while marking the unlit bulbs with a unqualified mark. Finally, the unloading mechanism 700 unloads the qualified and unqualified products separately. This fully automated testing replaces traditional manual operation, avoiding human error and rhythm fluctuations. The testing process is continuous and accurate, significantly shortening the testing time for a single batch of products.

[0023] Reference Figures 4 to 5According to some embodiments of this application, the feeding mechanism 300 includes a feeding platform 310, a material-catching frame 311, a first moving device 320, a second moving device 330, a material-catching movable plate 340, a material-catching bracket 341, a material-catching lifting cylinder 342, a material-catching movable seat 343, a material-catching pneumatic finger 350, and a material-catching pneumatic gripper 351. The feeding platform 310 is located at one end of the frame 100, the material-catching frame 311 is located at the top of the frame 100, and the material-catching frame 311 is close to the feeding platform 310. The first moving device 320 is located at the top of the material-catching frame 311 and is parallel to the length direction of the frame 100. The second moving device 330 is located at the top of the first moving device 320. Parallel to the width direction of the frame 100, the material-catching movable plate 340 is located on one side of the second moving device 330, the material-catching bracket 341 is located on one side of the material-catching movable plate 340, the material-catching movable seat 343 is slidably connected to the material-catching movable plate 340, the material-catching lifting cylinder 342 is located on the top of the material-catching bracket 341, the material-catching lifting cylinder 342 drives the material-catching movable seat 343 to rise and fall, there are multiple material-catching pneumatic fingers 350, the multiple material-catching pneumatic fingers 350 are located at the bottom of the material-catching movable seat 343, there are multiple material-catching pneumatic grippers 351, and two are grouped together, the multiple groups of material-catching pneumatic grippers 351 are respectively located at the bottom of the material-catching pneumatic fingers 350, the material-catching pneumatic fingers 350 drive the adjacent group of material-catching pneumatic grippers 351 to open and close.

[0024] Understandably, the light bulbs to be tested are placed in batches on the loading platform 310. When the bulbs are being loaded, the first moving device 320, the second moving device 330, and the material-catching lifting cylinder 342 bring the bottom material-catching pneumatic fingers 350 close to the bulbs. The material-catching pneumatic fingers 350 drive the adjacent set of material-catching pneumatic grippers 351 to open and cover the bulbs. Then, the adjacent set of material-catching pneumatic grippers 351 closes to facilitate the grabbing of the bulbs on the loading platform 310. After successful grabbing, the material-catching lifting cylinder 342 drives the material-catching movable seat 343 to rise, lifting the bulbs away from the loading platform. After the first moving device 320 and the second moving device 330 work together again, the movable seat is driven to descend again by the material-grabbing lifting cylinder 342, inserting the bulb's lamp base into the lamp holder 221 on the conveyor plate 220. The material-grabbing pneumatic finger 350 controls the material-grabbing pneumatic gripper 351 to open, accurately releasing the bulb and placing it on the lamp holder 221. After release, the material-grabbing pneumatic finger 350 rises and moves back to the loading platform 310 position, ready for the next grabbing cycle, thus completely replacing the manual work of placing the bulb, seamlessly connecting with subsequent testing, and forming a complete automated closed loop.

[0025] Reference Figures 4 to 5According to some embodiments of this application, the feeding mechanism 300 includes a plurality of material-catching movable cylinders 352, which are disposed on the outer edge of the material-catching movable seat 343. The piston rods of the plurality of material-catching movable cylinders 352 are respectively connected to a plurality of material-catching pneumatic fingers 350, so that the material-catching movable cylinders 352 drive the material-catching pneumatic fingers 350 to move.

[0026] Understandably, in order to achieve stable and non-destructive gripping, each gripping pneumatic finger 350 is driven by an independent gripping movable cylinder 352, so that each gripping movable cylinder 352 drives the gripping pneumatic finger 350 connected to it to make fine adjustments in the horizontal direction. This allows each set of gripping pneumatic gripping fingers 351 to adaptively center according to the actual position and size of the bulb, ensuring that the gripping pneumatic gripping fingers 351 can move precisely to the optimal gripping position of the bulb head.

[0027] Reference Figure 6 According to some embodiments of this application, the heating mechanism 400 includes a heating mounting box 410 and a plurality of heating rods 430. The heating mounting box 410 is located at the bottom of the frame 100 and below the transmission chain 211. The top of the heating mounting box 410 has an inner mounting cavity 420, and the plurality of heating rods 430 are respectively located inside the inner mounting cavity 420.

[0028] Understandably, when the conveying mechanism 200 carries a bulb that is in a constantly lit state to the heating mechanism 400, the heat from the multiple heating rods 430 is directly applied to the bulb passing directly above it through thermal radiation and upward thermal convection. Since the transmission chain 211 moves at a constant speed, each bulb will undergo a heating process of the same duration above the heating area, ensuring that the thermal stress test on each product is consistent. This avoids fluctuations in test conditions caused by unstable heating sources, position changes, or differences in human operation during manual testing, and greatly improves the reliability and comparability of test results.

[0029] Reference Figure 7 According to some embodiments of this application, the lamp inspection mechanism 500 includes an inspection frame 510, an inspection device 520, and an inspection cylinder 530. The inspection frame 510 is installed on the top of the frame 100 and is located on one side of the heating mounting box. There are multiple inspection cylinders 530, which are disposed inside the inspection frame 510. There are multiple inspection devices 520, which are respectively disposed inside the multiple inspection cylinders 530.

[0030] Understandably, the heated bulbs are carried by the conveyor 200 to the lamp inspection mechanism 500. When each bulb moves directly under its corresponding inspection cylinder 530, it enters a local dark chamber created by the inspection cylinder 530. This cylindrical structure effectively shields the ambient light in the factory, providing a stable and interference-free measurement background for optical inspection. Inside each inspection cylinder 530, an independent inspection device 520 (usually a photoelectric sensor or optical probe pointing towards the bulb) is installed. When the bulb enters the range of the inspection cylinder 530, the inspection device 520 captures the light emitted by the bulb and converts it into an electrical signal, thereby facilitating the test of whether the bulb remains lit.

[0031] Reference Figure 8 According to some embodiments of this application, the coding mechanism 600 includes a coding frame 610, a third moving device 620 and a coding device 630.

The third moving device 620 is horizontally disposed on one side of the coding frame 610 and the coding device 630 is disposed on one side of the third moving device 620.

[0032] Understandably, when the conveying mechanism 200 transports a light bulb that has completed light inspection to the coding mechanism 600, the existing control system generates a coding mark (qualified or unqualified) for the light bulb based on the inspection results of the light inspection mechanism 500. The third moving device 620 drives its coding device 630 to move, so that the coding device 630 can accurately align with the optimal coding area of ​​the light bulb to be coded.

A defective product pneumatic finger 734 is mounted on the bottom of the first lifting seat 733. There are two defective product grippers 735. The two defective product grippers 735 are mounted on the bottom of the defective product pneumatic finger 734. The defective product pneumatic finger 734 drives the two defective product grippers 735 to open and close.

[0034] Understandably, when the control system of the prior art detects that a bulb marked as defective has moved to the discharge mechanism 700, the first displacement device 720 drives the first displacement plate 730 to move, positioning the defective pneumatic finger 734 directly above the defective bulb. The first lifting cylinder 732 is activated, pushing the first lifting seat 733 to descend, so that the defective gripper finger 735 at the bottom approaches the defective bulb. The defective pneumatic finger 734 drives the two defective gripper fingers 735 to close, thereby capturing and discharging the defective bulb.

[0035] Reference Figures 9 to 10 According to some embodiments of this application, the discharge mechanism 700 includes a second support frame 741, a second displacement device 740, a second displacement plate 750, a second mounting frame 751, a second lifting cylinder 752, a second lifting seat 753, a good-quality pneumatic finger 754, and a good-quality gripper finger 756.

The good quality pneumatic fingers 754 drive the adjacent set of good quality grippers 756 to open and close.

[0036] Understandably, when the existing control system detects that a bulb marked as good has moved to the discharge mechanism 700, the second displacement device 740 drives the second displacement plate 750 to move, positioning the good product pneumatic finger 754 directly above the good product bulb. The second lifting cylinder 752 is activated, pushing the second lifting seat 753 to descend, so that the bottom good product gripper 756 approaches the good product bulb. The good product pneumatic finger 754 drives the two good product grippers 756 to close, thereby grabbing and discharging the good product bulb.

[0037] Reference Figures 9 to 10 According to some embodiments of this application, the discharge mechanism 700 includes a plurality of fine-tuning cylinders 755, which are disposed on the outer edge of the second lifting seat 753. The piston rods of the plurality of fine-tuning cylinders 755 are respectively connected to a plurality of good product pneumatic fingers 754, so that the fine-tuning cylinders 755 drive the adjacent good product pneumatic fingers 754 to move.

[0038] Understandably, each good-quality pneumatic finger 754 is driven by an independent fine-tuning cylinder 755, which causes each fine-tuning cylinder 755 to drive the connected good-quality pneumatic finger 754 to make fine adjustments in the horizontal direction. This allows each set of good-quality pneumatic fingers 754 to adaptively center according to the actual position and size of the good-quality bulb, ensuring that the good-quality gripper finger 756 can move precisely to the optimal gripping position of the bulb head.

[0039] Reference Figure 2 According to some embodiments of this application, the conveying mechanism 200 includes two sets of transmission sprockets 210 and a transmission motor 212. There are four transmission sprockets 210, with two sprockets forming a group. The two sets of transmission sprockets 210 are respectively located on both sides of the inside of the frame 100. The transmission chain 211 is sleeved on the outside of two adjacent transmission sprockets 210, so that the transmission sprockets 210 are in transmission cooperation with the two adjacent transmission sprockets 210. The transmission motor 212 is located on one side of the frame 100, and the transmission motor 212 drives the adjacent set of transmission sprockets 210 to rotate.

[0040] It is understandable that when the drive motor 212 starts, the drive motor 212 drives an adjacent set of drive sprockets 210 to rotate, thereby driving the drive sprockets 210 to transmit power, so as to transport the light bulb.

Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
