All kinds of screws need to undergo numerous process treatments to complete a perfect quality and satisfactory finished product. The manufacturing process must go through a number of cumbersome processes from the beginning, drilling, boring, heat treatment, electroplating, etc. For the screw industry, how to hand over the finished product to the customer, the quality control becomes a screw practitioner. An important topic. In addition, the cost of raw materials has continued to rise in recent years, the exchange rate has appreciated, the export tax rebate has been lowered, and the implementation of the labor contract law has resulted in unfavorable manufacturers factors such as increased labor costs. The simple relying on manual testing has not met the current fiercely competitive screw environment.
So, how do you choose the right screw screening machine?
First, let's first introduce the traditionally manual detection method:
1. Thread ring gauge, flat ring gauge
2.PinGauge/plug gauge
3. Bolt gauge
4. Vernier caliper, length gauge
5. Thickness gauge / limit gauge
6. Eccentricity
7. Projector
8. Roller mechanism screening
9. Manual visual inspection <
The above several detection methods belong to the traditional detection method, which requires a lot of human resources, a lot of time and cost. In view of resource utilization considerations, manufacturers often take sampling methods to test products for customers, which makes it easy to increase quality doubts. The risk of defective products also increases. In addition, the quality of the inspection is also closely related to the operator. The quality of the testing personnel is uneven, the new members develop the gap, or the physical strength of the personnel, operating habits and other unmeasured variables will also have a certain impact on the quality.
The optical screening machines on the market are mainly used for projection. The following are necessary to pay attention to the selection:
1. Screening speed
Speed ​​determines production capacity. If you want to use a machine to replace a lot of manpower testing, speed must be the primary consideration. In the market, machine sellers have different opinions on M8 products, ranging from 200 pic/min to 500 pic/min. Basically, in addition to the feed speed, the detection content and the camera image capture speed also have a certain influence. In general, M8 products should be qualified above 450pic/min under normal inspection items.
2. Screening accuracy
Most people think that if you want to improve the accuracy, you must improve the camera configuration. In fact, the accuracy will be affected by the light and the lens. Most manufacturers will recommend you to purchase high-precision cameras to improve the accuracy of the test, but in many cases, the appropriate light source and lens can meet customer needs, and don't forget that high-precision cameras will increase computer processing time and affect detection. speed.
3. Sharing
Screws, processing parts are thousands of styles, and the size is even more. The industry's choice of automatic screening machines, including the style and sharing of parts is also a big consideration. Some screening machines can only be applied to one product, and even can only be applied to a single size. Therefore, the investment of the industry cannot be exerted, and the main purpose of replacing human detection and cost saving cannot be achieved. For those with multiple products, it is a big burden on cost.
4. After-sales service and optical software
In addition to the usual customer service problems, it is also necessary to pay attention to hardware warranty and software update capabilities. Especially in software with high technical thresholds, this problem is particularly prone to occur. Most manufacturers outsource to other manufacturers, often in the process of processing speed or update timeliness. The manufacturer must know more about the problems that have arisen in this aspect.
5. Test items
There is not much problem with the basic size measurement of the machine sold in the market. At present, there are few manufacturers that can actually do it (for example: head crack, crush, blockage, deformation, etc.), but the screw is inevitably produced in the production process, and it takes a lot of resources to use manual inspection. Frequently let the screw industry hurt the brain. In fact, if the light is properly designed and designed for the characteristics of the product so that the reflection of the light is correctly projected onto the lens, the above-mentioned crushing can easily be solved.
6. Integrity
The screening machine must be considered in terms of optical requirements, and the construction of the mechanism design is also very important. Whether the feeding is smooth or not, and whether the delivery of the good products and the elimination of defective products after the completion of the test actually account for a large factor in the purchase of the machine.
In recent years, customers have become more and more strict with precision requirements and delivery time. Automated screening machines are gradually favored by the screw industry. In the future, the highly competitive screw industry is bound to become an indispensable role. With the large number of screws being used in various industries, optical automatic screening machines/detectors have sprung up in recent years. For the screw industry, it is necessary to carefully select a machine to detect diversified products.
