What is the difficulty for screw counting?

There are several aspects to the difficulty of screw counting, the first is that there are many screw models, large screws a few centimeters long, small M1 screws a few millimeters long. Automatic counting machine equipment must first have the function of counting various types of screws. This requires software algorithms to have this ability. At the same time, the screw size should be taken into account at the feeding port of the vibrating plate. The screws on some precision devices, such as those used on mobile phones, are very small. Some feed ports for conveying materials and other considerations will use different concave and convex surface effects on the bottom and side, if it is too small screws, it is easy to stay in the feed port slot when the vibration voltage is small. At the same time, whether the shape of the vibration plate is flat, as well as the size design of the fine feeder, should meet the needs of various models at the same time. These technical points should be determined at the beginning of the design. These two problems are very testing the technical precipitation and the experience of the design team.

The variety of screw models will also bring another problem, the problem of frequent replacement of materials. Our screw vision counting machine has a more mature learning-free algorithm program, materials can start counting directly without learning. This greatly reduces the time to learn and check repeatedly before counting various types of screws, improving work efficiency.

The counting requirements of the screw industry are usually the number of single packets is relatively large and the counting speed is required, which brings a great challenge to the accuracy. Such as quickly counting 1000 screws, but also as efficient as possible, the camera capture and algorithm requirements are extremely demanding. Take this VBP series of our company as an example, this is a typical VBP series equipment, and because the counting material is a screw, the whole machine adopts a relatively compact design, which is more convenient to control the quantitative counting process, for small materials can not only achieve mass counting, but also achieve small batch counting. In addition, another highlight of this equipment is the consideration of safety standards, so when working, each door is accidentally opened will think of the security alarm and light up the yellow light, and the equipment will randomly stop operation. Including the acrylic protective cover above also applies to this security algorithm.
