Abstract

The invention discloses gantry double-drive dynamic double-head high-speed high-precision dispensing equipment and a gantry double-drive dynamic double-head high-speed high-precision dispensing control system. The gantry double-drive dynamic double-head high-speed high-precision dispensing equipment comprises a cabinet, a conveying track is arranged in the middle of the top surface of the cabinet, the conveying track is sequentially provided with a feeding station, a dispensing station and a discharging station from left to right, and a Y1 axis and a Y2 axis are arranged on the top surface of a rack; an X-axis stator is arranged on a cross beam between the Y1 axis and the Y2 axis, an X1-axis rotor and an X2-axis rotor are arranged on the X-axis stator, a first dispensing valve, visual equipment and a laser displacement sensor are arranged on a Z1 axis, a macro motor is arranged on a Z2 axis, and a second dispensing valve is arranged at the working end of the macro motor; and according to the equipment, a motion control unit, a transmission control unit, a machine vision system and a signal data acquisition and dispensing control unit are gathered in a bus manner, communicate with each other and transmit data, so that the high-speed and high-precision dispensing process of products is completed, the operation stability of the dispensing process is ensured, and the automation integration level of the control system is improved.

Description

technical field [0001] The invention relates to the technical field of glue dispensing equipment, in particular to a double-head, high-speed, high-precision glue dispensing equipment and a control system in a gantry double-drive state. Background technique [0002] The dispensing process is widely used in the consumer electronics production industry to complete the coating, sealing, filling or coating of electronic components on electronic products; the commonly used precision dispensing machine drives at this stage generally use servo motors and lead screws Structural form, the control scheme uses high-frequency pulse signal instructions to send to the servo driver, the servo driver drives the servo motor and the carrier to realize the positioning movement, the servo motor connects the screw structure, drives the load and the movement of the dispensing valve body, and the dispensing machine equipment is also used The linear motor drives the load and the control scheme of th...

Problems solved by technology

[0004] The dispensing equipment with servo motor and lead screw mechanical structure cannot meet the requirements of higher speed and higher precision dispensing capacity and dispensing process under the conditions of speed below 1.5m / s and acceleration of 1g. Unilateral motor drive For the dispensing machine, when the dispensing valve and other loads are at the other end of the control side, when the running speed is high, the mechanical structure will be slightly bent due to the unbalanced thrust, which affects the positioning accuracy of the entire stroke section, and long-term high-speed operation , will also have a deformation effect on the aging characteristics of the mechanical structure of the system;

[0005] The dispensing machine equipment is equipped with a dispensing valve body of a single type of adhesive to dispensing a single type of adhesive medium. When it is necessary to realize the dispensing process of two different types of adhesives, a single dispensing valve is available. limited

[0006] Although there are precision dispensing equipment for mixed dispensing with different types of glue, due to the mechanical mechanism characteristics of the servo screw, it can only be used for synchronous or asynchronous dispensing under the same operating conditions of the main shaft. The specification has strict restrictions: it must be similar and regular in shape, the height requirement of the processed product, and the effective dispensing area range of the two sets of dispensing valve bodies;

[0007] For the status monitoring of common dispensing equipment, the information collection of components is generally relatively simple, especially the monitoring of core control components such as motors, drivers, and controllers lacks process information, which is not conducive to the flexible management of factory automation
