Description

Technical Field

[0001] This utility model relates to the field of H7 bulb technology, specifically to a device for detecting unsoldering in automotive H7 bulbs. Background Technology

[0002] In automotive lighting systems, H7 bulbs have become a commonly used light source due to their outstanding advantages. They consist of a filament, a glass housing, and a lamp holder. The filament is made of a special material that allows it to emit light efficiently when energized. The glass housing protects the filament and optimizes the light output, while the lamp holder connects to the vehicle's electrical system, ensuring stable bulb operation. H7 bulbs are commonly used in automotive headlights and fog lights, providing crucial illumination for drivers at night and in inclement weather, and are closely related to driving safety.

[0003] Solder joints are crucial for the electrical connection and mechanical fixation of H7 bulbs, and their quality directly affects bulb performance. Open solder joints result in poor metal bonding, increased resistance, excessive heat during bulb operation, shortened lifespan, and may even cause flickering or complete extinguishing of the light due to poor contact, severely impacting illumination and threatening driving safety.

[0004] Traditional methods for detecting cold solder joints in automotive H7 bulbs mostly rely on manual visual inspection or simple mechanical testing equipment. Manual visual inspection is not only inefficient, but the results are also greatly affected by subjective factors such as the inspector's experience and fatigue, easily leading to missed or false detections. Simple mechanical testing equipment often only detects basic features such as the appearance of the solder joint, making it difficult to accurately determine whether there are more hidden defects such as cold solder joints inside the joint. To quickly and accurately detect cold solder joints in H7 bulbs, ensuring product quality and driving safety, we propose a cold solder joint detection device for automotive H7 bulbs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a device for detecting open solder joints in automotive H7 bulbs. This device can quickly and accurately detect open solder joints in H7 bulbs, ensuring product quality and driving safety.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device for detecting unsoldered bulbs in automotive H7 models includes a workbench, a controller on the top of the workbench, a rotating disk rotatably mounted on the top of the workbench, several sets of placement plates fixedly connected to the top of the rotating disk, placement cavities matching the bulbs on the placement plates, a detection component for detecting unsoldered bulbs on the workbench, a loading component for placing the bulbs to be tested onto the placement plates on the workbench, and a unloading component for classifying and conveying the tested bulbs to the next process on the workbench.

[0008] The detection component includes a second support frame, which is fixedly connected to the top of the workbench. On one side of the second support frame close to the rotating disk, an upper mounting plate and a lower mounting plate are fixedly connected. An infrared emitter is fixedly installed at the bottom of the upper mounting plate, and an infrared receiver matching the infrared emitter is fixedly installed at the top of the lower mounting plate. A power mechanism for intermittently rotating the rotating disk is installed on the workbench.

[0009] Preferably, the power mechanism includes a servo motor, which is fixedly installed at the top of the inner cavity of the workbench, and the output end of the servo motor is fixedly connected to the bottom of the rotating disk.

[0011] Preferably, the discharging component includes two discharging robotic arms, which are fixedly installed at the top of the workbench, and two discharging conveyor belts matching the discharging robotic arms are fixedly installed at the top of the workbench.

[0012] Preferably, a first support frame is fixedly connected to the top of the workbench. On one side of the first support frame close to the feeding conveyor belt, a mounting frame is fixedly connected, and a ccd camera is fixedly installed on the mounting frame.

[0014] The utility model provides a vehicle-used H7 bulb non-welding detection device. Compared with the prior art, it has the following beneficial effects:

[0015] For this vehicle-used H7 bulb non-welding detection device, the bulb is placed on the rotating disk through the feeding component, and the rotating disk is rotated by the power mechanism, so that the bulb rotates between the infrared emitter and the infrared receiver. At this time, the solder joints on the bulb will block the infrared rays. If the signal received by the infrared receiver is not blocked, it means that the bulb has non-welding, otherwise it means that the bulb is qualified. Thus, the non-welding detection of H7 bulbs can be carried out quickly and accurately, ensuring the product quality of H7 bulbs and guaranteeing driving safety. Brief description of the drawings

[0022] 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.

[0023] Please see Figure 1-5 This utility model provides a technical solution: a vehicle H7 bulb unsoldering detection device, including a workbench 1, a controller 7 on the top of the workbench 1, a rotating disk 2 rotatably mounted on the top of the workbench 1, a number of placement plates 11 fixedly connected to the top of the rotating disk 2, placement cavities matching the bulbs on the placement plates 11, a detection component for unsoldering detection of the bulbs installed on the workbench 1, a loading component for placing the bulbs to be detected onto the placement plates 11 installed on the workbench 1, and a unloading component for classifying and conveying the detected bulbs to the next process installed on the workbench 1;

[0024] The detection assembly includes a second support frame 16, which is fixedly connected to the top of the workbench 1. An upper mounting plate 17 and a lower mounting plate 20 are fixedly connected to the side of the second support frame 16 near the rotating disk 2. An infrared transmitter 18 is fixedly installed at the bottom of the upper mounting plate 17, and an infrared receiver 19 matching the infrared transmitter 18 is fixedly installed at the top of the lower mounting plate 20. A power mechanism that drives the rotating disk 2 to rotate intermittently is installed on the workbench 1.

[0025] In use, the bulb is placed into the placement cavity on the placement plate 11 by the feeding component. The rotating disk 2 is driven by the power mechanism to rotate, and the placement plate 11 rotates. When the bulb rotates between the infrared transmitter 18 and the infrared receiver 19, the solder joint on the bulb will block the infrared light. If the signal received by the infrared receiver 19 is not blocked, it means that the bulb has a blank solder joint. Otherwise, it means that the bulb is qualified. This allows for quick and accurate detection of blank solder joints in H7 bulbs, ensuring the product quality of H7 bulbs and ensuring driving safety. Finally, the qualified and unqualified bulbs are sorted and transported to the next process by the unloading component.

[0026] The power mechanism includes a servo motor 15, which is fixedly installed on the top of the inner cavity of the worktable 1, and the output end of the servo motor 15 is fixedly connected to the bottom of the rotating disk 2.

[0027] The servo motor 15 drives the rotating disk 2 to rotate intermittently at a certain angle. The rotation interval matches the detection time, and the rotation angle matches the angle between the placement plates 11.

[0028] The feeding assembly includes a feeding robotic arm 3, which is fixedly installed on the top of the workbench 1. A feeding conveyor belt 4 that matches the feeding robotic arm 3 is fixedly installed on the top of the workbench 1.

[0029] The light bulb to be tested is placed on the feeding conveyor belt 4, which transports the light bulb to the feeding robotic arm 3. The feeding robotic arm 3 picks up the light bulb and places it into the placement cavity on the placement plate 11.

[0030] The unloading assembly includes two sets of unloading robotic arms 5, which are fixedly installed on the top of the workbench 1. Two sets of unloading conveyor belts 6 that match the unloading robotic arms 5 are fixedly installed on the top of the workbench 1.

[0031] After the inspection is completed, the two sets of unloading robotic arms 5 pick up the qualified and unqualified light bulbs respectively according to the inspection results and place them on the corresponding unloading conveyor belt 6, thereby realizing the classified unloading.

[0032] A first support frame 12 is fixedly connected to the top of the workbench 1. A mounting frame 13 is fixedly connected to the side of the first support frame 12 near the feeding conveyor belt 4. A CCD camera 14 is fixedly installed on the mounting frame 13. The CCD camera 14 is located above the feeding conveyor belt 4. A connecting block 8 is provided on both the feeding robotic arm 3 and the unloading robotic arm 5. A motor 9 is fixedly installed on the top of the connecting block 8. A gripper cylinder 10 is rotatably installed on the bottom of the connecting block 8. The output end of the motor 9 is fixedly connected to the gripper cylinder 10.

[0033] The angle of the incoming light bulb is captured and recorded by the CCD camera 14, and the motor 9 is controlled to drive the gripper cylinder 10 to rotate at the corresponding angle, so that the gripper cylinder 10 can accurately pick up the light bulb.

[0034] Both the feeding conveyor belt 4 and the unloading conveyor belt 6 are equipped with several sets of conveying chambers that match the light bulbs, making it convenient to transport the light bulbs.

[0035] Working Principle: During operation, the bulb to be tested is placed on the feeding conveyor belt 4, which transports it to the feeding robotic arm 3. The robotic arm 3 picks up the bulb and places it into the placement cavity on the placement plate 11. The servo motor 15 drives the rotating disk 2 to rotate, causing the placement plate 11 to rotate. When the bulb rotates between the infrared transmitter 18 and the infrared receiver 19, the solder joints on the bulb will block the infrared light. If the signal received by the infrared receiver 19 is not blocked, it indicates that the bulb has a void solder joint; otherwise, the bulb is qualified. This allows for quick and accurate void solder joint detection of H7 bulbs, ensuring product quality and ensuring vehicle safety. After the detection is completed, two sets of unloading robotic arms 5 pick up qualified and unqualified bulbs according to the detection results and place them on the corresponding unloading conveyor belt 6 for transport to the next process. During this process, the CCD camera 14 captures and records the angle of the incoming bulb, controlling the motor 9 to drive the gripper cylinder 10 to rotate at the corresponding angle, enabling the gripper cylinder 10 to accurately pick up the bulb.
