Description
Technical Field
[0001] This utility model relates to the field of pin loop detection technology, and in particular to a loop detection device. Background Technology
[0002] In modern manufacturing, with the increasing complexity of product design and the continuous pursuit of production efficiency, the demand for automated testing equipment is gradually increasing. Especially in the production of electronic products and medical devices, the quality of the product's pins directly affects its performance and safety. Therefore, developing efficient and accurate testing equipment is of paramount importance.
[0003] Currently, traditional testing methods typically rely on multiple workstations and manual operation, requiring products to be manually placed at each testing stage. This method has several major problems:
[0004] Long inspection cycle: Because products need to be manually moved between different workstations, the overall inspection cycle is extended, affecting production efficiency.
[0005] Human error: When manually placing products, workers may make mistakes in positioning or operation, resulting in unnecessary losses and the outflow of unqualified products.
[0006] Large equipment footprint: Traditional multi-station testing layouts often occupy a large space, making the production line design inflexible and unable to adapt to rapid changes in production needs.
[0007] Delayed data recording and feedback: In manual inspection, the real-time recording and analysis of data are often delayed, affecting the efficiency of quality management.
[0008] Therefore, it is essential to invent a loop detection device. Utility Model Content
[0009] To address the aforementioned technical problems, this utility model provides a loop inspection device to solve the issues of existing loop inspection devices requiring frequent movement of the inspection pins, ineffective removal of defective products, and disjointed inspection processes. The loop inspection device includes a support structure, a product, a flipping station, a continuity / discontinuity inspection station, a continuity / discontinuity NG gripping station, a first height inspection station, a first height NG gripping station, a second height inspection station, a second height NG gripping station, a finished product gripping station, a product conveying structure, and a conveyor belt. The product is placed in an initial position at the top of the support structure. The flipping station, continuity / discontinuity inspection station, continuity / discontinuity NG gripping station, first height inspection station, first height NG gripping station, second height inspection station, second height NG gripping station, and finished product gripping station are sequentially arranged and fixedly installed on the support structure. The product conveying structure is located in front of the support structure, and the conveyor belt is also located in front of the product conveying structure.
[0010] The continuity testing station includes a mounting base, a support frame, a bottom support plate, a bottom push rod, a bottom base plate, and a lower probe. The mounting base is fixedly mounted on the support structure, and the support frame is fixedly mounted on the surface of the mounting base. The bottom support plate is fixedly mounted on the front side of the lower part of the support frame, and the bottom push rod is fixedly mounted on the bottom support plate. The bottom base plate is fixedly mounted on the top of the bottom push rod. The lower probe is fixedly mounted on the bottom base plate.

[0012] The lower and upper probes inside the continuity testing station are supported by the surrounding structure and can move via bottom and top push rods. These probes contact both ends of the product pins. Both probes are connected to a circuit tester and serve the following functions: ① Continuity testing: By contacting both ends of the product pins, the lower and upper probes detect in real time whether current can pass through, determining whether the pin circuit is closed or open; ② Defect detection: Identifying potential electrical faults such as poor continuity or short circuits in the product, ensuring the normal function of each product's pins and preventing defective products from entering subsequent processes; ③ Data recording and feedback: Recording and feeding back the test results to the control system for adjustments to subsequent operations. The continuity NG (Not Acceptable) grabbing station removes unqualified products, ensuring a smooth production process.
[0013] The product conveyor structure employs a set of conveyor belts, and its precise stopping position is achieved via a servo motor. A product support fixture is mounted on the conveyor structure. The shape of the fixture above the conveyor structure matches the initial placement position, stably preventing the product pins to be inspected from being inserted. The conveyor structure can move the product pins through each inspection station and stop below each station, serving the following functions: ① Product movement: It is responsible for conveying the products to be inspected from the initial position to each inspection station, achieving automated product transfer; ② Precise positioning: Through servo motor control, it ensures that the product stops at a precise position below each inspection station, facilitating subsequent inspection operations; ③ Improved efficiency: Through continuous conveying and automatic stopping, it reduces manual intervention and improves the overall production line efficiency; ④ Collaboration with the inspection system: The product conveyor structure works in conjunction with the inspection stations to form a highly efficient automated inspection process, ensuring that each product smoothly passes through the necessary inspection steps.
