Description

Technical Field

[0001] This invention relates to the field of component testing technology, and in particular to a component continuity testing device. Background Technology

[0002] Optical isolators are core passive components in optical communication systems, laser equipment, and optoelectronic instruments. Their core function is to enable unidirectional transmission of optical signals and block reverse light interference. Their switching performance directly determines the signal stability and operational reliability of downstream equipment. Therefore, during the mass production of optical isolators, each component must undergo switching performance testing to eliminate defective products such as those with internal optical path faults or poor pin contact. This testing step has become a critical process in the optical isolator production chain to ensure product quality.

[0003] As the optoelectronics industry develops towards higher precision and higher production capacity, existing continuity testing devices for optically isolated components are gradually revealing core defects that are incompatible with the needs of large-scale production. These defects are specifically manifested in the following two aspects: On the one hand, existing testing equipment only has a single continuity test function and lacks automatic material sorting capability. After testing, qualified and unqualified components remain mixed on the conveyor path, requiring manual sorting and classification. Human visual fatigue and operational errors lead to the mixing of qualified and unqualified products, necessitating secondary inspections, which significantly increases production cycle and labor costs. At the same time, there is a quality risk that unqualified products may flow into downstream customers.

[0004] On the other hand, the existing device's material feeding structure is simple and crude, leading to significant secondary damage to components. After testing, components fall freely into the collection box directly from the end of the conveyor belt, without any cushioning or protective structure. Optically isolated components, with their small package size and soft lead material, are prone to secondary damage when colliding with the bottom of the collection box or other components during free fall. This not only causes qualified components to be mistakenly judged as defective due to material feeding damage, resulting in wasted raw materials, but also further damages already defective components, hindering subsequent source analysis of the faults.

[0005] In summary, the industry urgently needs a continuity detection device for optically isolated components that can combine automatic material sorting with slow-fall protection to address the shortcomings of existing devices, such as low sorting efficiency and high secondary damage rate. Therefore, we propose a continuity detection device for optically isolated components. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the present invention provides a component continuity detection device, which overcomes the problems of low sorting efficiency and high secondary damage rate of the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: The component continuity detection device is characterized by comprising: Conveyor, inspection gate mechanism, and sorting and slow-discharge mechanism; Spacers are equidistantly arranged on the conveyor belt of the conveyor to separate components; The inspection gate mechanism is installed on the conveyor and is used to test the electrical connection of components. The sorting and slow-discharge mechanism is installed at the discharge end of the conveyor and is used to sort components and protect them during the sorting process.

[0008] Furthermore, the partition plate is made of acrylic sheet, and the conveyor metal parts are made of aluminum profiles.

[0009] Furthermore, the detection gate mechanism includes a gate frame, a wide-angle mask, and a camera. The gate frame is installed on the conveyor body, and power blocks are set on both sides of the inner side of the gate frame. A camera is installed at the top inside the frame, and a wide-angle mask is set on the feeding side of the frame.

[0010] Furthermore, the classification and slow-fall mechanism includes a receiving mechanism, a slow-fall mechanism, and a bearing guard plate. The bearing guard plate is fixedly connected to the metal parts of the conveyor. Slide grooves are provided on both sides of the inner side of the bearing guard plate, and an arc groove is connected above the slide grooves. The receiving mechanism is installed on the metal parts of the conveyor and is close to the material dropping end of the conveyor. The receiving mechanism is supported by the bearing guard plate. The slow-fall mechanism is installed on the metal part at the material drop end of the conveyor. The slow-fall mechanism swings on the metal part of the conveyor and is set in the middle of the receiving mechanism and is driven to swing by the receiving mechanism.

[0011] Furthermore, the receiving mechanism includes a worm gear reducer, a swing arm, and a movable flap assembly. The worm gear reducer is mounted on the metal parts of the conveyor and is close to the material dropping end of the conveyor. A pair of swing arms are vertically arranged at both ends of the worm of the worm gear reducer. The movable flap assembly is slidably arranged on the bearing guard plate and is hinged to the swing arms.

[0012] Furthermore, the movable flip panel assembly includes a slide table, on which a bearing tube, a first slide rod, and a second slide rod are disposed through. The first slide rod and the second slide rod are on the same horizontal plane. The first slide rod slides in a slide groove and an arc groove, and the second slide rod slides in a slide groove. A push-pull rod is hinged between the bearing tube and the swing rod.

[0013] Furthermore, the slow-fall mechanism includes a material drop box, a rotating rod, and a traction rod. The rotating rod is set on both sides of the metal part at the material drop end of the conveyor. The material drop box passes through the rotating rod and swings on the rotating rod. A traction rod is set between the material drop box and the first sliding rod. The two sides of the traction rod are respectively hinged to the first sliding rod and the material drop box. A pull-out partition is set at the bottom of the material drop box for unloading.

[0014] Furthermore, the material drop box is shaped like a chair.

[0015] The beneficial effects of this invention are: This invention uses a detection gate mechanism to detect the continuity of optical isolators. The conveyor works intermittently, pushing the isolators forward via a partition plate. Normally detected optical isolators fall onto a sliding table. A worm gear reducer in the receiving mechanism swings counter-clockwise, with the first sliding rod sliding in a chute and an arc groove, and the second sliding rod sliding in the chute, pushing the normally detected optical isolators to the next process. For optical isolators with defects, the worm gear reducer in the receiving mechanism swings counter-clockwise, with the first sliding rod sliding in the chute and arc groove, causing the dropping box to tilt. The conveyor continues to operate, allowing the defective optical isolators to slide into the dropping box, preventing secondary damage to the defective components. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] In one embodiment, see Figures 1 to 8 A component continuity detection device, characterized in that it includes: The system comprises a conveyor 1, a detection gate mechanism 2, and a sorting and slow-feeding mechanism 3. The conveyor 1 intermittently delivers optically isolated components to the detection gate mechanism 2 for inspection. The sorting and slow-feeding mechanism 3 separates the optically isolated components that are deemed normal or defective by the detection gate mechanism 2. The partition plates 11 are made of acrylic sheets, and the metal parts of the conveyor 1 are made of aluminum profiles. Accessories are readily available and assembly is convenient. The partition plates 11 are equidistantly arranged on the conveyor belt of the conveyor 1 to separate the components. Optically isolated components are placed between each pair of partition plates 11. The detection gate mechanism 2 is installed on the conveyor 1 and is used for electrical connection testing of the components. The sorting and slow-feeding mechanism 3 is installed at the discharge end of the conveyor 1 to sort the components and protect them during the sorting process.

[0019] In one embodiment, see Figure 4 The detection gate mechanism 2 includes a gate frame 21, a wide-face mask 22, and a camera 23. The gate frame 21 is mounted on the conveyor 1 body. Power-conducting blocks 24 are set on both sides of the inner side of the gate frame 21. A camera 23 is set on the top of the inner side of the gate frame 21. A wide-face mask 22 is set on the feeding side of the frame 21. The wide-face mask 22 is open to facilitate the confirmation of the position of the optical isolation component when it enters the gate frame 21. When the camera 23 captures the position of the optical isolation component at the power-conducting block 2, the power-conducting block 2 begins to confirm.

[0020] In one embodiment, see Figures 5 to 8 The classification and slow-falling mechanism 3 includes a receiving mechanism 4, a slow-falling mechanism 5, and a bearing guard plate 6. The bearing guard plate 6 is fixedly connected to the metal parts of the conveyor 1. Slide grooves 61 are provided on both sides of the inner side of the bearing guard plate 6, and an arc groove 62 is connected above the slide grooves 61. The receiving mechanism 4 is installed on the metal part of the conveyor 1 and is close to the material dropping end of the conveyor 1. The receiving mechanism 4 is supported by the bearing guard plate 6. The slow-fall mechanism 5 is installed on the metal part at the material drop end of the conveyor 1. The slow-fall mechanism 5 swings on the metal part of the conveyor 1. The slow-fall mechanism 5 is set in the middle of the receiving mechanism 4 and is driven to swing by the receiving mechanism 4.

[0021] The receiving mechanism 4 includes a worm gear reducer 41, a swing arm 42, and a movable flap assembly 7. The worm gear reducer 41 is mounted on the metal part of the conveyor 1 and is close to the material dropping end of the conveyor 1. A pair of swing arms 42 are vertically arranged at both ends of the worm of the worm gear reducer 41. The movable flap assembly 7 is slidably arranged on the bearing guard plate 6 and is hinged to the swing arm 42.

[0022] The movable flip panel assembly 7 includes a slide table 71, on which a bearing tube 72, a first slide rod 73, and a second slide rod 74 are disposed. The first slide rod 73 and the second slide rod 74 are on the same horizontal plane. The first slide rod 73 slides in the slide groove 61 and the arc groove 62, and the second slide rod 74 slides in the slide groove 61. A push-pull rod 75 is hinged between the bearing tube 72 and the swing rod 42.

[0023] The optical isolating components are tested for continuity by the detection gate mechanism 2. The conveyor 1 works intermittently, pushing forward by the partition plate 11. The conveyor 1 delivers the optical isolating components that have passed the test to the slide table 71. The worm gear reducer 41 of the receiving mechanism 4 swings counterclockwise, acting on the swing rod 42. The swing rod 42 pushes the push-pull rod 75, causing the first slide rod 73 to slide in the slide groove 61 and the arc groove 62, and the second slide rod 74 to slide in the slide groove 61. This causes the slide table 71 to tilt to the right, pushing the optical isolating components that have passed the test to the next process. Then the worm gear reducer 41 swings clockwise to return to its original state. The slow-fall mechanism 5 is located inside the receiving mechanism 4. The slow-fall mechanism 5 includes a dropping box 51, a rotating rod 52, and a traction rod 53. The rotating rod 52 is set on both sides of the metal part at the dropping end of the conveyor 1. The dropping box 51 passes through the rotating rod 52 and swings on the rotating rod 52. The traction rod 53 is set between the dropping box 51 and the first sliding rod 73. The two sides of the traction rod 53 are respectively hinged to the first sliding rod 73 and the dropping box 51. A pull-out partition 54 is set at the bottom of the dropping box 51. The pull-out partition 54 is used for unloading. The dropping box 51 is chair-shaped.

[0024] The continuity of the optical isolating components is detected by the detection gate mechanism 2. The conveyor 1 works intermittently, pushing forward by the partition plate 11 to detect optical isolating components with defects. The worm gear reducer 41 first swings counterclockwise. The counterclockwise swing of the worm gear reducer 41 through the receiving mechanism 4 acts on the swing rod 42. The swing rod 42 pushes the push-pull rod 75, causing the first slide rod 73 to slide in the slide groove 61 and the arc groove 62, and the second slide rod 74 to slide in the slide groove 61. The dropping box 51 tilts, and the slide table 71 moves away. The conveyor 1 continues to work, and the optical isolating components with defects slide into the dropping box 51. They slide to the bottom of the dropping box 51 to avoid secondary damage to the optical isolating components with defects. Then the worm gear reducer 41 swings clockwise to restore the original state, and the dropping box 51 slowly becomes upright.
