The basic debugging skills of any machinery, including non-standard automation equipment, are "horizontal, vertical, and concentric". First of all, no matter how to debug any product, we must understand its characteristics and customer's technical requirements. Let me introduce some common debugging techniques for you.
1) Understand product characteristics (including appearance, dimensions, tolerances, structure, craftsmanship, etc.).
2) Wipe the parts (including standard parts and non-standard processed parts) clean, pick out the most core parts, and start assembly and debugging from the most core parts. During the assembly process, the accuracy of the installed parts should be checked and measured to ensure horizontal, vertical, and concentricity problems.
3) For single-cylinder push-pull or lifting parts, it should be ensured that the pull is in place and the push is also in place, and there should be no abnormal resistance.
4) Rotating part
The balance, verticality, and concentricity of the rotating part should be ensured. In order to achieve the accuracy of swing arm and indexing.
5) Pins, card slots
The areas with pin holes and card slots should be wiped clean, choose the appropriate pin (the hardness of the pin material is above 58 degrees), and locate it. The pin should be tightly matched on one side to facilitate disassembly and assembly; the accuracy of the card slot should be controlled within Within 0.02 to ensure the accuracy during the secondary assembly, the interior needs to be polished to prevent product scratches and scratches.
The feeding part of the material channel is mostly determined by the product, and the tolerance zone is about 0.1. It can ensure that the product passes through the material channel unimpeded. The feeding direction of the forehearth parts and the chamfering angle of the joint should be 0.2*30 degrees as the standard, and the specific situation depends on the product. Feeder
7) Lead screw, slide rail
When assembling, pay special attention to the nut and the slide rail, and do not slide out of the screw rod and slide rail to prevent the balls from falling out and causing the product to be scrapped or affecting the accuracy. After ensuring the parallelism, perpendicularity and concentricity of the parts during assembly, proceed with assembly. In order to prevent the unqualified parts from fixing and deforming the screw rod and the slide rail during assembly, resulting in scrapping.
8) Speed adjustment of the valve
The speed of the valve should be the best condition that can just transport the product away without affecting the production efficiency. If the valve speed is too fast, it will vibrate or the product will flutter; if it is too slow, it will reduce production efficiency. (Note that we usually use the exhaust throttle valve)
9) Common component adjustment and troubleshooting
a) Magnetic switch (often called sensor), cylinder induction is divided into front sense and rear sense. The front adjustment sensor pushes the front sense to the front end of the cylinder, and the cylinder stroke should also be at the front end. At this time, the sensor should be in the off state, and it is appropriate to push the sensor back from the front end to just bright. The adjustment method is the same as above.
b) The optical fiber is adjusted according to the specifications of different brands. The operation is different but the principle is the same. Pay attention to the difference between the reflective fiber and the opposite beam fiber.
10) Vibration plate, direct vibration
Vibration plate and direct vibration are divided into two parts: vibration part and control part. The vibration part is mainly a vibrating magnet, and the control part is a vibration controller. The controller has a power switch button, and voltage and frequency buttons. If the vibration frequency is too high, the product will vibrate or go back; if the vibration is too small, the product will move slightly or not. If the vibration frequency and voltage are adjusted to the maximum, the vibrating plate or direct vibration still slightly shakes, you should check whether the gap between the electromagnets or the steel sheet is loose or broken. The gap between the electromagnets is between 0.5-1mm. Adjust appropriately according to the situation.
The above are some simple debugging techniques. When assembling non-standard automation equipment, using these techniques reasonably and flexibly can help you quickly debug successfully. Improve the economic efficiency of the enterprise and reduce the production cost of the equipment.
