Application of robotic fixtures in the new and old automotive industry

- Sep 14, 2019-

As an important part of high-end equipment, industrial automation products are an important prerequisite and guarantee for modern industrial production to achieve scale, high efficiency, precision, intelligence and safety. With the development of traditional industrial technology transformation, factory automation and enterprise informationization, industrial automation System requirements will continue to grow. As far as the integration of the entire robot system is concerned, the problem that often arises or is relatively unstable is the non-standard part of the end execution unit. Here are some examples of our previous cases, to share with you some of the application cases of robotic automatic loading and unloading fixtures (also called robotic grippers) in the new and old automotive industry.


1. The use of the robot gripper in the automatic upper and lower line of the crankshaft. The crankshaft of the workpiece is the key component of the vehicle power system. The machining precision is high. The clamp adopts the radial clamping position of the upper end of the crankshaft, and the workpiece is clamped in the axial direction by the initial correction. With the workpiece in place detection sensor. It is used in the engine assembly line to realize the robot automatically grabs the crankshaft, scans the QR code, reads the information, and the upper part is installed in the online engine block. Due to the high precision of the machining of the workpiece itself and the high precision of the matching, high requirements are also placed on the system for automatic feeding. This automatic loading and unloading system is used to replace the manual manual process, to reduce the labor intensity of human beings and to achieve the purpose of robot replacement. This type of gripper is suitable for automatic loading and unloading applications of small and medium-sized shaft and round bar parts.


2, the robot gripper in the new energy lithium battery manufacturing process of the automatic use of the battery. The workpiece core is the core component of the power battery of the new energy vehicle. The square aluminum alloy shell has an outer surface which is a non-machined surface. The clamp adopts a parallel clamping method to sandwich the two sides of the battery core and the workpiece. In place detection sensor. The gripper is used for the automatic feeding process of the battery core in the module manufacturing process. Since the precision of the workpiece being grasped is not too high, the precision requirement of the whole set of loading and unloading is slightly lower than that of Fig. 1. This type of gripper is suitable for automatic loading and unloading applications for small and medium square parts.


3. The robot gripper automatically uses the cylinder head in the engine assembly process. The cylinder head of the workpiece is the core component of the traditional automobile powertrain. It is generally manufactured and manufactured by the vehicle manufacturer. It is an important part of the machining of the engine. The processing requirements are high and the processing steps are also numerous. The gripping method of the gripper is to use the large machined surface support, the technology pin hole positioning, the side cam mechanism to clamp the workpiece, and the workpiece in-position detecting sensor, which can meet the sharing of various models, and is equipped with The 180 degree angle mechanism is used to achieve the purpose of switching direction during the loading and unloading process. The gripper is equipped with the XZ two-axis truss robot, which requires high reliability, running accuracy and running speed. This type of gripper is suitable for automatic loading and unloading applications of medium square parts.


4. The robot gripper automatically applies the end plate insulation film in the manufacturing process of the new energy lithium battery. The end plate of the workpiece being transported is an important part of the power battery module of the new energy vehicle. It belongs to the cast aluminum part and the end surface is finished. The clamp adopts the parallel clamping method, and the workpiece in-position detecting sensor is used to clamp the end plate. side. The workpiece insulating film is lightly weighted and has a large deformation variable. Therefore, the suction plate is used for suction, and the side-correcting automatic positioning clamping method is adopted during the grasping process. The gripper is used for automatically picking, cleaning, placing and placing the end plate and the insulating film in the module manufacturing process, and simultaneously grabbing two workpieces at the same time, belonging to the composite gripper, in the process of picking and discharging, and the like. The structure avoids interference and has high requirements. This type of gripper is suitable for automatic loading and unloading applications of light and small square parts.


The robot gripper uses the automatic feeding of the flywheel bearings during the engine assembly process. The workpiece bearing to be conveyed is a precision component of the conventional automobile powertrain, and belongs to an important component with high precision in the assembly process of the engine. The clamping method of this set of grippers is to adopt the method of bearing end face positioning and three-claw tensioning positioning and clamping of the inner hole, and the universal type is strong. At present, it is suitable for automatic feeding and clamping of three kinds of large and small bearings, with the lifting and lowering mechanism, the swinging mechanism, the feeding linear servo shaft and the servo press machine to complete the automatic grabbing, inspection, upper part, positioning, press fitting, etc. In the process, the position accuracy of the workpiece and the material to be picked by the gripper is relatively high. This type of gripper is suitable for automatic loading and unloading applications for miniature round parts.


The robot gripper uses the side panels and modules automatically in the manufacturing process of the new energy lithium battery. The workpiece module to be transported has a large weight, and the whole module is clamped by means of servo clamping and mechanical spring force compensation. The gripper is used for the process of automatically picking, cleaning, placing and positioning the side panels and modules in the module manufacturing process, and simultaneously grabbing 3 workpieces at the same time, belonging to the composite gripper, during the picking and discharging process and other The structure avoids interference and has high requirements. This type of gripper is suitable for automatic loading and unloading applications for small sheet metal parts as well as square parts.


Mechanical processing, automobile manufacturing, food and chemical industry, military and aerospace. Under the trend of automation, the goal of “machine substitution” has been promoted step by step, and smart manufacturing is beginning to be gradually realized.
