When the AGV trolley completes the automatic handling and loading operations, in addition to ensuring the safety of the AGV itself and the normal operation of the various functions of the AGV, it is also necessary to protect the safety of personnel and operating environment facilities to the greatest extent possible. Therefore, the purchase of AGV guided vehicles should consider the following safety protection measures:
① The exterior of the vehicle body is free of dangerous parts such as sharp corners and other protrusions.
② Obstacle contact bumpers must be installed on the AGV body.
③ The obstacle approach detection device is preferably a multi-stage approach detection device. Generally, the obstacle proximity detection device has more than two levels of safety protection settings. If it is within a certain distance, it will slow down the AGV, and at a closer distance, it will cause the AGV to stop, and when the obstacle is lifted After loading, the AGV will automatically resume normal driving.
④ The safety protection device of the automatic loading and unloading implementing agency. Generally, in the same vehicle, both mechanical and electrical protection devices are provided, which are related to each other and produce protection.
⑤ AGV must be equipped with multiple alarm devices. Including: Auto running indicator: when AGV is running automatically, the indicator is on; when AGV is in non-auto running status, the indicator is on and off. Warning light: When the AGV enters the running state from the stop state, when the AGV is in the reverse running state or when the AGV is abnormal, an audible and visual alarm is issued.
⑥Emergency stop device: AGV must have an emergency stop device to maintain itself in case of sudden abnormal conditions.
⑦Status monitoring device: Monitor the running status of the AGV, especially when the AGV is abnormal, it can have a monitoring function to understand the status and its cause.
(2) Basic parameters and performance indicators
When selecting an AGV, consider the following basic parameters and performance indicators:
AGV guidance method;
AGV drive type;
AGV dead weight (excluding battery);
Rated carrying capacity
Battery type and charging method;
Continuous working time
Alarm and emergency stop devices;
(3) After-sales service
In order to ensure the safe, reliable and good operation of AGV, it is important to provide high-quality comprehensive after-sales service and technical services. It is mainly manifested in the following aspects:
①Respond quickly to customer opinions, letters, telephones and faxes.
② Make non-scheduled return visits, and actively understand the delivered AGV system project, and remediate and solve problems if found.
③System maintenance and fault repair. Improve the AGV maintenance manual. When the AGV fails, it can quickly organize and perform on-site fault repairs and respond quickly.
④Provide the latest AGV system technical information, provide new suggestions and technical advice for AGV system product and software version upgrades, and ensure and extend the life cycle of the supplied AGV system and equipment.
⑤Provide users with timely, comprehensive and high-quality technical services. Design, installation, maintenance and operation training for relevant personnel of users.
(4) Application scenario analysis
The solution of the AGV trolley is customized according to the customer's actual application scenario and should meet production needs and future development. The application scenario needs to be analyzed as follows:
① AGV operation route (the position of the upper and lower material points and the material transportation sequence between the points).
② Beat of conveying (how often is conveyed and requirements of production line materials).
③ The size and packaging style of the product to be transported.
④ The form of loading and unloading (latent type, trailer type, roller docking type, piggyback type, manual loading and unloading, etc.), planning the transportation route to achieve the shortest path, simple and smooth.
