Description

Technical Field

[0001] This application relates to the field of high-frequency electrosurgical unit (ESU) production equipment, and in particular to a circular assembly line type high-frequency ESU appearance and electrical safety integrated testing machine. Background Technology

[0002] In the field of medical device manufacturing, electrocautery scalpels, as a common surgical instrument, directly affect the safety and effectiveness of surgeries due to their product quality. Therefore, comprehensive inspection of appearance defects, dimensional accuracy, assembly integrity, and electrical safety performance is a crucial and mandatory step in the production process. Currently, the industry primarily relies on two models for quality inspection of such products: one is purely manual visual inspection, where operators judge each product individually based on their eyes and experience under specific lighting conditions; the other is the use of rudimentary automated equipment, such as simple conveyor belts coupled with one or a few fixed sensors for single-item inspections, such as dimensional measurements or continuity tests.

[0003] However, all the aforementioned existing technical solutions have significant limitations. Manual inspection relies heavily on operator focus and experience, and is prone to inconsistencies in inspection standards due to fatigue, emotional fluctuations, and subjective judgment, leading to missed detections and misjudgments. This is especially true for minor defects such as micron-level scratches and uneven coatings, where the identification rate is difficult to guarantee. This not only poses a potential product quality risk but also results in low inspection efficiency, becoming a bottleneck for large-scale production. While preliminary automation solutions improve efficiency to some extent, their functions are often too singular and fragmented. Multiple independent inspection units are scattered across different locations on the production line, lacking systematic integration and data linkage, resulting in lengthy production processes, large floor space requirements, and the risk of secondary damage due to multiple loading, unloading, and positioning processes for each product. More importantly, appearance inspection and functional safety testing are usually separated, and data cannot be correlated. When non-conforming products occur, it is difficult to quickly trace whether the cause is an appearance defect or an electrical performance failure, hindering accurate analysis and optimization of the production process.

[0004] Therefore, it is necessary to develop an integrated automated system that can highly integrate multiple inspection processes, link data from each inspection unit in real time, and ultimately achieve intelligent judgment and sorting. Utility Model Content

[0005] The purpose of this application is to overcome at least one deficiency of the existing technology and provide a circular assembly line type high-frequency electrosurgical unit appearance and electrical safety comprehensive inspection machine, which helps to improve the production efficiency of electrosurgical units and ensure the reliability of product quality.

[0006] To achieve the above objectives, this application discloses a circular assembly line type high-frequency electrosurgical unit (ESU) appearance and electrical safety integrated testing machine. The equipment includes a machine base, a rotary table, and a control unit. The rotary table achieves intermittent indexing rotation and vertical lifting combined motion through a built-in reciprocating drive mechanism. The control unit is connected to a servo driver via a distributed I / O module to control the precise positioning of the reciprocating drive mechanism. This drive mechanism uses a servo drive in conjunction with a reduction gear to achieve precise indexing positioning and a linear guide mechanism to achieve precise vertical lifting.

[0007] The machine has five functional stations arranged sequentially along the circumference of the rotary table, which are used for material loading and cleaning, visual inspection, electrical testing, laser marking, and sorting and unloading. Multiple pneumatic clamping mechanisms distributed on the rotary table use double-acting cylinders to drive the clamps, and are equipped with pressure sensors to monitor the clamping force. The control unit adjusts the clamping force through a pneumatic solenoid valve group to ensure accurate positioning and smooth transfer of workpieces between each station.

[0008] The first workstation is equipped with a positioning fixture and cleaning components. The positioning fixture features a V-shaped positioning groove and an adjustable limiting mechanism. The cleaning components include an exhaust system and a suction system arranged opposite each other. The exhaust system has an array of nozzles with adjustable nozzle spacing and angle; the suction system has a negative pressure suction port with an opening size matched to the workpiece shape. The control unit adjusts the speed of the high-pressure blower through an analog output module to achieve precise airflow pressure control; simultaneously, it adjusts the negative pressure value of the vacuum generator through a proportional valve to form a closed-loop control. The suction system and dust collection system adopt a quick-connect structure, and the dust collection system uses a multi-layer filtration design, including multiple filtration layers.

[0009] The second workstation is equipped with a machine vision inspection unit, including a high-resolution industrial camera, optical lens, and lighting device. The control unit is connected to the image processing unit via an industrial Ethernet interface. The image data acquired by the industrial camera is processed and used for defect identification and dimensional measurement. The brightness of the lighting device is adjusted via a PWM signal output from the control unit.

[0010] The third workstation is equipped with an electrical performance testing device, including an insulation resistance testing module and a continuity testing module. The control unit controls the output of the test voltage via a digital interface. The insulation resistance testing module can output various DC test voltages to measure insulation resistance within different ranges. The continuity testing module uses a multi-wire measurement principle and can provide various test currents. The test probes are made of gold-plated material and achieve reliable contact with the workpiece via a pneumatic device. The contact pressure is adjusted by the control unit using a pneumatic pressure valve. During testing, the control unit automatically applies the specified test voltage, measures the insulation resistance and loop resistance values, and monitors safety parameters in real time via a high-speed acquisition module. The device is equipped with a self-calibration circuit; the control unit periodically triggers a calibration sequence for value traceability and accuracy verification.

[0011] The fourth workstation integrates a laser marking device, employing a fiber laser and a vision positioning component. The control unit controls the galvanometer system via a motion control card, and simultaneously acquires workpiece position information from the vision positioning component via an image acquisition card, performing coordinate compensation calculations to ensure accurate marking position. The marking content is obtained in real time through the control unit's database interface.

[0012] The fifth station is equipped with a sorting and output device. The control unit controls the flow distribution mechanism via a servo driver based on the detection results, guiding qualified and unqualified products to different output channels. The speed of the conveyor mechanism is adjusted by the control unit using the frequency converter output frequency.

[0013] The entire testing process of this device is conducted by the control unit, which exchanges data with the actuators and sensors at each workstation via an industrial bus. The control unit is equipped with a human-machine interface for parameter setting, status monitoring, and production data statistics. All testing data is uploaded in real-time to the data storage device via a network communication module, where it is linked to the product serial number and stored to generate a complete testing report and quality traceability record. The equipment adopts a modular design, with each functional unit connected to the control unit via a standard interface, allowing for independent debugging and maintenance, and supporting rapid model changeover and functional expansion.
