Description

Technical Field

[0001] This utility model relates to the technical field of filament testing equipment, and more specifically, to a filament testing mechanism for automotive H7 bulbs. Background Technology

[0002] As a crucial component of automotive lighting systems, the quality and performance of H7 bulb filaments directly impact nighttime driving safety. Current technologies for inspecting H7 bulb filaments have several shortcomings. Traditional manual inspection relies on workers visually inspecting the filament for breaks or deformations. This method is inefficient, slow, and unsuitable for large-scale production. Furthermore, manual inspection is highly susceptible to subjective factors; differing judgment standards among inspectors lead to inconsistent and inaccurate results, potentially resulting in defective products entering the market. Some companies use simple electrical testing equipment to check filament conductivity, which quickly determines filament energization but fails to detect minute damage or internal structural defects. While high-precision testing equipment, such as electron microscopes, can perform microscopic filament inspection, their large size, high cost, and complex operation make large-scale application on production lines difficult, causing inconvenience to daily operations. Therefore, improvements are needed. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1 to 7 As shown, this utility model provides a filament detection mechanism for automotive H7 bulbs, comprising:

[0030] The work platform 1 has a tray 2 placed on its top and a first cylinder 3 fixedly installed at its bottom. A connecting block 4 is fixedly installed at the right end of the first cylinder 3. The outer surface of the connecting block 4 is slidably connected to the inside of the work platform 1. A moving block 5 is fixedly installed at the top of the connecting block 4.

[0031] The clamping mechanism is located on the left and right sides behind the top of the work platform 1;

[0032] The testing agency is located at the top of the work platform 1;

[0033] The clamping mechanism includes two columns 6, which are fixedly installed on the left and right sides of the top rear of the work platform 1. Guide rails 7 are fixedly installed on the top of each column 6. Fixing frames 8 are fixedly installed on the back of the two columns 6. A second cylinder 9 is fixedly installed on the back of the fixing frame 8. A fixing plate 10 is fixedly installed on the front end of the second cylinder 9. A slider 11 is fixedly installed on the bottom end of the fixing plate 10. The slider 11 is slidably connected to the inside of the guide rail 7. A first pneumatic gripper 12 is fixedly installed inside the fixing plate 10.

[0034] When the operator starts the second cylinder 9, the second cylinder 9 will drive the first gripper 12 to move back and forth through the fixed plate 10. At this time, the fixed plate 10 will drive the slider 11 to move along the inside of the guide rail 7. Due to the design of the guide rail 7 and the slider 11, the movement of the fixed plate 10 will be more stable. Due to the design of the first gripper 12, when the operator starts the first gripper 12, the first gripper 12 can simultaneously clamp multiple light bulbs inside the tray 2 and transport them to the inside of the moving block 5, thereby achieving the effect of efficient light bulb transportation. When the first cylinder 3 is running, the connecting block 4 will drive the moving block 5 to move left and right intermittently.

[0035] The testing institutions include:

[0036] Support plate 13, there are two support plates 13, the bottom ends of the two support plates 13 are fixedly connected to the top of the working platform 1, and the outer surfaces of the two support plates 13 are respectively fixedly installed with a second pneumatic gripper 14 and a third pneumatic gripper 15.

[0037] The bottom of the power-on detection module 16 is fixedly connected to the top of the work platform 1. A current sensor 17 is fixedly installed on the right side of the top of the work platform 1. A rotating block 20 is movably connected to the front side of the top of the work platform 1. Two arc-shaped blocks 21 are fixedly installed on the left and right sides of the front side of the top of the work platform 1. A camera 22 and a lighting lamp 23 are respectively installed on the two arc-shaped blocks 21.

[0038] When the bulb is inside the power-on detection module 16, the power-on detection module 16 and the current sensor 17 will detect the power-on status of the bulb. If the bulb malfunctions, the current sensor 17 will shut down the equipment and sound an alarm, prompting nearby operators to remove the bulb from the power-on detection module 16. When the bulb is inside the rotating block 20, the lighting lamp 23 will illuminate the rotating block 20, making the filament more clearly visible. At the same time, the camera 22 will capture images of the filament and transmit the images to the display screen so that the operator can observe the condition of the filament. When the rotating block 20 rotates the bulb, it can adjust the orientation angle of the filament so that the camera 22 can capture clear images of the filament. Since the second pneumatic gripper 14 is equipped with two grippers, when the second pneumatic gripper 14 is running, it can transport the bulb inside the moving block 5 to the power-on detection module 16, and at the same time transport the bulb inside the power-on detection module 16 to the rotating block 20. When the third pneumatic gripper 15 is running, it can clamp and move the bulb inside the rotating block 20.

[0039] Among them, a drive motor 18 is fixedly installed at the bottom of the work platform 1, and a rotating shaft 19 is fixedly sleeved at the other end of the output shaft of the drive motor 18. The outer surface of the rotating shaft 19 is movably sleeved with the inside of the work platform 1, and the top of the rotating shaft 19 is fixedly sleeved with the inside of the bottom of the rotating block 20.

[0040] When the drive motor 18 is running, the rotating shaft 19 will drive the rotating block 20 to rotate.

[0041] The bottom of the work platform 1 is fixedly installed with a support 24, and a reinforcing rod 33 is provided on the support 24.

[0042] Due to the design of the support 24, it can provide good support for the entire working platform 1, so that the entire working platform 1 can be placed stably on the ground. Due to the design of the reinforcing rod 33, it can enhance the overall structural strength of the support 24.

[0043] Among them, a top plate 25 is fixedly installed on the front side of the top of the support 24, and a round shaft 26 is movably sleeved inside the left side of the top of the top of the top plate 25. A driven wheel 27 is fixedly sleeved on the outer surface of the round shaft 26.

[0044] Because the circular shaft 26 is internally and movablely connected to the top plate 25, the driven wheel 27 can drive the circular shaft 26 to rotate around the connection point with the top plate 25.

[0045] Among them, a power motor 28 is fixedly installed on the right side of the bottom end of the top plate 25, and a vertical shaft 29 is fixedly sleeved on the other end of the output shaft of the power motor 28.

[0046] When the power motor 28 is running, the vertical shaft 29 will rotate.

[0047] Among them, a drive wheel 30 is fixedly sleeved on the outer surface of the vertical shaft 29. The drive wheel 30 is connected to the driven wheel 27 through a transmission belt 31. A movable block 32 is fixedly installed at the top end of the transmission belt 31.

[0048] Due to the design of the movable block 32, the third pneumatic gripper 15 can transport the bulb inside the rotating block 20 to the interior of the movable block 32. When the vertical shaft 29 rotates, it will drive the driven wheel 27 to rotate through the transmission belt 31. At this time, the movable block 32 will move under the drive of the transmission belt 31, and the movable block 32 will transport the bulb.

[0049] Working principle and usage process of this utility model:

[0050] First, the operator places the tray 2 filled with light bulbs on the top of the work platform 1. Then, the operator activates the second cylinder 9. The front end of the second cylinder 9 drives the first gripper 12 to move back and forth through the fixed plate 10. At this time, the slider 11 slides along the inside of the guide rail 7 under the drive of the fixed plate 10. Due to the design of the slider 11 and the guide rail 7, the fixed plate 10 is more stable when moving back and forth. Then, the operator activates the first gripper 12. Since the first gripper 12 is equipped with a slide rail, the gripper on the first gripper 12 can move left and right along the slide rail. When the gripper on the first gripper 12 moves to directly above the light bulb, the operator manipulates the first gripper 12 to move the gripper on the first gripper 12 downward to grab the light bulb. Since the first gripper 12 is equipped with four grippers, it can efficiently grab the light bulb. After the first gripper 12 has finished grabbing the light bulb, it will return to its original position. Then, these light bulbs will be transported into the interior of the moving block 5 under the drive of the second cylinder 9 and the first gripper 12.

[0051] The operator then activates the first cylinder 3. The output of the first cylinder 3, via the connecting block 4, drives the moving block 5 to move intermittently left and right, allowing the four bulbs inside the moving block 5 to align sequentially with the second gripper 14. The operator then activates the second gripper 14. Since the second gripper 14 has two grippers, when it operates, one gripper will grasp the bulb inside the moving block 5, while the other gripper will simultaneously grasp the bulb inside the power-on detection module 16 that has completed the power-on detection. When both grippers have finished gripping the bulb, one gripper on the second pneumatic gripper 14 will transport the bulb inside the moving block 5 to the power-on detection module 16 for power-on detection, while the other gripper will transport the bulb inside the power-on detection module 16 for power-on detection to the rotating block 20 for photographic detection. Due to the design of the current sensor 17, the power-on status of the power-on detection module 16 will be detected. If the bulb filament is faulty, the current sensor 17 will send a signal to stop the entire equipment and issue an alarm to attract the operator's attention and remove the faulty bulb.

[0052] When the bulb is placed inside the rotating block 20, each of the current illumination lamps 23 illuminates the bulb to highlight the shape of its internal filament. At the same time, the camera 22 takes pictures of the bulb and filament, and these pictures are then displayed on the operator's monitor so that the operator can observe and inspect the bulb filament. When the operator observes that the filament is damaged in the picture, the equipment will be stopped to remove the bulb with the damaged filament. If the orientation angle of the filament inside the bulb affects the clarity of the camera 22's image, the camera 22 will send a signal to the drive motor 18 to run the drive motor 18. At this time, the rotating shaft 19 will drive the bulb to rotate through the rotating block 20, thereby adjusting the orientation angle of the filament inside the bulb, thus realizing the function of efficient and accurate detection of the bulb.

[0053] After the bulb inspection is completed, the operator activates the third pneumatic gripper 15. The gripper on the third pneumatic gripper 15 will then grab the bulb inside the rotating block 20. Once the gripper on the third pneumatic gripper 15 has grabbed the bulb, it will be transported to the interior of the movable block 32. Next, the operator activates the power motor 28. The vertical shaft 29 will then drive the drive wheel 30 to rotate. The drive wheel 30 will then drive the top plate 25 to rotate via the transmission belt 31. At the same time, the transmission belt 31 will drive the movable block 32 to move. During this process, the bulb will move under the drive of the movable block 32, thereby achieving the function of transporting the inspected bulb.
