About teaching robots

Teaching of FANUC industrial robots is a teaching method using a tool called a teaching pendant. There is a button on the teaching pendant that describes the operating direction of each axis, and you can operate it by using it. The feature is that teaching is performed using a function called a register. The register function is a function that registers a certain position as a reference and allows you to register points simply by entering a numerical value indicating how far the XYZ (up / down / left / right) direction is from that reference point to the next point. The advantage of this function is that it is highly suitable for the teaching “offline teaching” function on the PC. It is possible to create an accurate teaching program on a PC and reduce the work man-hours on site.

Introducing an example of our teaching as a countermeasure against welding defects in automobile parts factories. At the customer’s site, there were beat defects and blow holes, and in order to eliminate them, Shoei Techno Service technicians checked the site conditions and improved the welding conditions. Zinc has a low melting point (iron: about 1500 ° C, zinc: about 900 ° C), and zinc vaporizes and pulls up during welding. .. Therefore, as a countermeasure, welding while vaporizing and removing zinc with high heat input during welding is a method with a high possibility of improving welding defects. There are two main points when teaching. The first point is to make the torch posture straight or receding in order to increase heat input. There is a possibility that steam may be entrained at the forward angle, and it may be possible to expect the effect of sufficiently heating the welding pond and the base metal and increasing the heat input by setting the angle to face-to-face or receding. The second point is that the welding speed is slower than welding non-galvanized steel sheets. I think it’s easy to imagine that the slower the speed, the higher the heat input. If the voltage is increased to increase the heat input, the concentration of the arc will deteriorate, so select a voltage that matches the current. The above points are the points in galvanized welding.

Yaskawa industrial robots are taught using a programming pendant. Eight-axis operation buttons are arranged on the pendant, so that complicated switching is not required when operating the 7-axis robot or the external axis, and the axis name is written on the operation button, etc. The operability is easy to understand even for beginners. Also, if you use the 3D graphic display function when checking the robot operation after teaching, you can check the robot operation and program flow on the pendant without moving the actual machine, so it is difficult to actually move the robot. It is possible to do some teaching work. Since the latest model can change the linear operation speed of the robot to the maximum speed with a simple setting, there are many situations where the tact time can be expected to improve compared to the conventional model.

About robot rental

It can be rented. There is TM-1400WGⅢ, an arc welding robot made in 2014. For this model, it is possible to select the Rotational tilted external shaft and Activ specifications that realize low spatter welding as options. Since we have only one unit in stock, we may be renting it out, so please contact us each time for availability. In addition, when using robot rental, there are wires, shield gas, primary power supply, robot stand, jig table, jigs, etc. that customers need to prepare. For items that customers need to prepare, we have a list of materials with illustrations. If you contact us, we will send you the materials, so please feel free to contact us.

About robot maintenance

We maintain Panasonic industrial robots and FANUC industrial robots. For robots made by both Panasonic and FANUC, we not only replace consumable parts such as battery replacement and reducer grease replacement, but also perform inspections that require specialized knowledge and experience. Sudden production suspension due to a robot failure is a life-and-death problem for manufacturing customers. Before a sudden suspension of production occurs, we will identify the parts that are worn out in advance and perform systematic maintenance. By performing such preventive maintenance, production efficiency will increase dramatically and stable production can be achieved. In fact, major automatic parts manufacturers have been pleased that the number of robot failures has decreased dramatically since the inspection of industrial robots began to be carried out once a year. If you have any problems with sudden production suspension, please feel free to contact us.

Collaboration / cooperation About robots

There are a lot of inquiries about collaborative robots from the food industry. Recently, the use of robots in the food industry is accelerating due to the shortage of the working population, and among them, collaborative robots that can be used in collaboration with people. The demand for robots is increasing. The reasons for this are “space saving that can be used in the same area as a person” and “easy movement of installation location and switching of work contents”. In industrial robots, if the robot body plus the safety fence is included, the installation area will often be too large to fit in the space, but collaborative robots can overcome this, creating new space. It is useful in the food industry, which is often difficult. Another major advantage is that one robot can be relocated and reused in multiple processes in the food industry, where the operating lines fluctuate frequently due to production planning. One of the accepted factors is that the position correction after relocation can be simplified by using the camera function. At “FOOMA JAPAN (International Food Industry Exhibition)”, the number of exhibitions of automation systems using collaborative robots is increasing year by year.

Robot camera

There are various types of inspections, such as visual inspections for scratches, stains, burrs, and burns, shape inspections for checking dimensions, shapes, and the presence of accessory parts, and color inspections for identifying color unevenness, omissions, and color differences. The difficulty level of these differs depending on the material, such as whether the product is metal or resin, and the selection of the camera also differs accordingly. Basically, the camera manufacturer will select a model that can be used with industrial and collaborative robots. Recently, AI inspection devices are also on the market, and devices that can improve the accuracy while simplifying the setting by automatic learning of AI, which had been set by humans until now, are becoming common. Visual inspection by humans has been common until now, but for products with high production volume, more and more companies are considering shifting to automation with robots from the viewpoint of stable inspection accuracy and measures against labor shortage. The number of inquiries to our company is increasing.

About robot labor saving equipment

When introducing an industrial robot, 1. Specification definition, 2. Basic design, 3. Manufacture, 4. Pre-installation work, 5. Pre-shipment witness, 6. Delivery / startup, 7. Introduction (introduction support) It is roughly classified into 7 categories. It is also the most important process in this process, and the cooperation of users is 1. the specification definition. In this specification definition, the knowledge about Sier robots like ours and the knowledge, intuition, and tips about the customer’s work and work are well integrated, and it becomes the foundation for manufacturing good equipment. Once the specifications are decided, we will move on to designing and manufacturing, and after confirming the specifications before shipping, we will deliver it locally in the presence of the customer. Obviously, we will also provide installation support so that customers can use it after delivery. This series of steps generally takes about half a year to a year.
