Product background

The replacement of labor by machines is a general trend in the current manufacturing industry. Machines can replace people in industrial production to do a large number of monotonous, frequent and repetitive operations, or operations in dangerous and harsh environments. The production process of the machine is highly consistent, and the quality of the product is very stable, which can bring stable benefits to the enterprise; the machine can work continuously for 24 hours, the enterprise can accurately predict the output, and the inventory can also be better controlled. Every cost saving in the production process will be transformed into the competitiveness of the product in the market. Manufacturing enterprises have used a large number of smart devices to ensure product quality, improve production efficiency, and avoid industrial accidents. The capacitor manufacturing industry is in a period of transition from traditional equipment to intelligent manufacturing equipment. If an enterprise wants to grab a larger market share in the fierce competition and get rid of the homogeneous competition of products, it must improve the automation level of the production line. The introduction of advanced appearance inspection machines is a powerful technical means to realize the transformation and upgrading of the capacitor manufacturing industry.

Inspection principle:

The materials are arranged by vibrating plate, Linear vibration and non-destructive conveying, and the capacitance is stably and orderly transferred to the specific inspection station, and then the high-pixel sample image captured by the industrial camera is transferred to the image processing software. After the system analyzes and processes, it judges good and defective products, and controls the corresponding pneumatic components to eliminate the defective products, and finally collects qualified products.

Testing details:

The inspection machine adopts 14 sets of high-pixel industrial cameras and high-performance stroboscopic light sources to carry out omni-directional visual inspections for product appearance defects. The inspection speed is 400-600 pieces/min. The equipment can realize 7*24 hours of all-weather operation, and it can be online automatically. Eliminate substandard products.

The whole set of inspection equipment includes mechanical, visual electronic hardware and inspection system software. The entrance and exit of the equipment are reserved for docking positions to facilitate on-site operations.

2, system composition:

(1) Mechanical part:

The mechanical part is the core component of the system, which carries all the transmission devices and electronic hardware (industrial cameras, light sources, industrial computers, touch screens, electrical boxes, etc.). The conveyor is controlled by a servo motor, and the image capture is accurate. The equipment is equipped with two defective product inlets to separate serious defective products (such as drum bottom, oblique leather tip, etc.) and general defective products.

(2) Inspection software:

The software is the master control platform of the equipment, and its specific functions are as follows:

• Enabling and disabling the system detection function.
• Adjustment of the parameters and accuracy of detection indicators.
• Template sampling and storage, sample detection information storage and recall.
• Camera calibration
• Display system real-time production information (qualified rate, total output, speed, etc.). Browse, export and store historical production information.
• l Perform authority management according to the login account (for example, general operating users are prohibited from using parameter adjustment permissions)
• Operation and adjustment of the mechanical parts of the system (such as: air valve jet time adjustment, camera trigger time adjustment)
• Additional functions added due to customer needs

(3) Hardware part:

The hardware part includes cameras, lenses, light sources, high-speed air valves, industrial computers, touch screens and other electrical devices. For details, please refer to the equipment configuration details.

The overall logic control of the system is implemented by a high-speed FPGA chip.

Specific functions include:

• Trigger the light source strobe
• Trigger the camera to take a photo
• Trigger the solenoid valve to jet off waste products
• Control the belt speed
• Emergency treatment for system jams or similar situation
• Trigger the alarm light signalØ
