What matters should be paid attention to during the operation of tauren injection manipulator?

The tauren injection manipulator has the following precautions during operation:

I. Installation and debugging stage

Installation environment inspection

The manipulator should be installed in a dry and well-ventilated environment. Avoid installation in damp or corrosive gas places, because damp environment may cause electrical components to be damaged by moisture, and corrosive gas may corrode the metal parts of the manipulator.

Make sure that there is enough space in the installation position to facilitate the arm extension and rotation of the manipulator. Generally speaking, at least the maximum extension length of the arm plus 0.5-1m should be reserved around to prevent the manipulator from colliding with other objects during operation.

Mechanical installation accuracy control

When installing the manipulator, it is necessary to operate in strict accordance with the installation manual of the equipment to ensure the installation accuracy of all components. For example, the installation of mechanical arm should ensure that its levelness and verticality are within the allowable error range, and usually the levelness and verticality errors should not exceed 0.5. If the installation accuracy is not enough, it may lead to the deviation of the manipulator in the operation process, which will affect the accuracy of grasping and placing injection parts.

Electrical system debugging

When debugging the electrical system, check whether the wiring of each electrical component is correct. For example, the wiring of motors and sensors should be consistent with the circuit diagram of the control system to prevent short circuit or open circuit.

Set and calibrate the parameters of the control system. According to the requirements of the size, weight and production process of injection molded parts, the running speed, grasping force, action sequence and other parameters of the manipulator are reasonably set. In the process of debugging, it is necessary to test each parameter step by step to ensure that the manipulator can run stably and accurately.

Second, the operation stage

Safety protection measures

Operators must undergo professional training and be familiar with the operation process and safety precautions of the manipulator. During the operation of the manipulator, the operator should stay outside the safety fence to avoid any part of the body from entering the working area of the manipulator.

Ensure that safety devices such as safety light curtain and emergency stop button are in normal working condition. The safety light curtain can detect that people or objects enter the dangerous area and stop the operation of the manipulator in time; The emergency stop button should be installed in a conspicuous and easy-to-operate position. In case of emergency, you can immediately press the button to stop the manipulator.

Monitoring and adjustment of operation parameters

Monitor the running speed of the manipulator in real time. If the speed is too fast, it may lead to a large impact force when the manipulator grabs and places the injection parts, which may damage the injection parts or make the placement position of the injection parts inaccurate. However, if the speed is too slow, it will affect the production efficiency. Generally, the speed should be adjusted reasonably according to the weight and material of injection molded parts. For example, for lighter plastic bottle caps, the running speed can be appropriately accelerated; For the heavier injection molding shell, the speed should be slowed down appropriately.

Pay attention to the grasping force of manipulator. The grasping force should be adjusted according to the weight and shape of injection molded parts. If the grasping force is insufficient, the injection molded parts may fall off; If the grasping force is too large, it may damage the surface or structure of injection molded parts. The grasping force can be monitored and adjusted by devices such as pressure sensors.

Synchronous coordination with injection molding machine

The tauren injection manipulator needs to cooperate closely with the injection molding machine. Ensure that the action sequence and time of the manipulator match the production cycle of the injection molding machine. For example, when the injection molding machine completes injection molding and opens the mold, the manipulator should enter the mold in time to grab the injection molded part; After the manipulator places the injection molded parts in the designated position, it should return to wait for the next grab in time. By adjusting the communication parameters and control program of the manipulator and the injection molding machine, the good synchronization between them can be realized and the production efficiency can be improved.

Third, the maintenance and maintenance stage

Daily cleaning inspection

After work every day, the manipulator should be cleaned. Remove dust, oil and plastic debris from the mechanical hand. Special attention should be paid to cleaning the robot arm and joints, because the accumulation of debris in these parts may affect the movement flexibility of the manipulator.

Check all parts of the manipulator for signs of looseness and damage. For example, check whether the screws are tightened, whether the drive belt and chain are worn, and whether the sensor works normally. When problems are found, they should be dealt with in time to prevent the problem from expanding and affecting the normal operation of the manipulator.

Regular lubrication and maintenance

Regularly lubricate the joints, screw rods and other moving parts of the manipulator. According to the operating instructions of the manipulator, select appropriate lubricants, such as high-temperature grease, for joint parts to ensure that these parts can move smoothly during work. Generally speaking, lubrication is needed every 100-200 hours.

Care should be taken not to let lubricant pollute electrical components and injection molded parts during lubrication. If the lubricant comes into contact with electrical components, it may lead to short circuit or other faults; If it pollutes the injection molded parts, it may affect the quality of the injection molded parts.

Component replacement and maintenance

When the parts of the manipulator are found to be damaged or aged to a certain extent, they should be replaced in time. For example, when the motor has abnormal noise and insufficient power, or the accuracy of the sensor can not meet the requirements, the corresponding components should be replaced.

When repairing and replacing parts, use genuine parts that meet the specifications and operate in strict accordance with the steps in the maintenance manual. After maintenance, the manipulator should be debugged again to ensure that its performance returns to normal level.
