Embodiment 1

[0030] like figure 2 As shown, the basic structure of a dispensing valve and motion control synchronization system in this embodiment includes a motion control device 100 , a motion mechanism 200 , a dispensing valve 300 and a synchronous control device 400 . Wherein, the motion control device 100 is used to control the motion of the motion mechanism 200, and the motion mechanism 200 is used to drive the dispensing valve 300 to move. In other embodiments, the motion mechanism 200 can also be used to drive the product to be dispensed. The synchronous control device 400 is used to control the switching valve of the dispensing valve 300 to realize dispensing. The synchronous control device 400 includes a position sensing module 410 and a synchronous control module 420. The position sensing module 410 is used to obtain the position of the actual track point of the dispensing valve 300 Coordinates, so that the synchronous control module 420 can more accurately control the on-off v...

Embodiment 2

[0040] The difference between this embodiment and Embodiment 1 is that the method in this embodiment uses a vector position comparison method for position comparison, and when the target moves to a specified position (coordinates), the "trigger" is accurately performed to control the opening of the dispensing valve 300 For valve gluing, for a single axis, that is, one-dimensional, as long as the direction of motion is facing the target, this coordinate value will definitely be reached, but for multi-axis such as two-dimensional or three-dimensional, the actual trajectory may also be determined by multiple axes. Synthesized by coordinate movement control, there may be a certain deviation from the preset trajectory. The actual trajectory may deviate from the target position, such as the corner point when turning at a right angle. Therefore, the trigger condition cannot be simply set to "reach" the target position. .

Embodiment 3

[0053] This embodiment provides a control terminal, which includes a memory, a processor, and a computer program stored in the memory and operable on the processor. When the computer program is executed by the processor, the above-mentioned The steps of a method for synchronizing a dispensing valve with motion control.

[0054] The device in this embodiment is in the same concept as the methods in the first and second embodiments above, and its specific implementation process is detailed in the corresponding method embodiments, and the technical features in the method embodiments are applicable in this device embodiment. I won't go into details here.

Abstract

The invention discloses a system, a method, a control terminal and a storage medium for synchronizing a dispensing valve with motion control, and belongs to the technical field of dispensing. The system includes a synchronous control device, and the synchronous control device is used to synchronously control the on-off valve of the dispensing valve according to the motion mechanism; the method includes: the synchronous control device regularly obtains the position coordinates of the actual track point of the dispensing valve, and compares it with the preset command The position is compared to determine whether it has reached the command position. Obtain the position coordinates of the dispensing valve movement in real time through the position sensing module, which is more accurate than the "command position" in the existing control system method, and can better achieve the effect of "pointing where to hit"; the control of the motion mechanism The control of the on-off valve of the dispensing valve and the dispensing valve is respectively controlled by the motion control device and the synchronous control device to avoid mutual interference and reduce the error caused by the signal source. The system and method in the present invention can minimize the position Errors that occur during synchronization.

Description

technical field [0001] The present invention relates to the technical field of dispensing, more specifically, it relates to a system, a method, a control terminal and a storage medium for synchronizing dispensing valves and motion control. Background technique [0002] Glue dispensing is a commonly used process in the industrial field. Specifically, it refers to attaching a liquid with a certain viscosity to the target path by spraying or squeezing. The extrusion method is under constant pressure (usually air pressure) on the needle tube, and the needle travels at a constant speed to set a path to meet the process requirements. The extrusion method is currently very mature. For the jetting method, in addition to the accurate movement path, the process also needs to accurately control the interval between each glue point. In addition, when spraying, there is a lag between when the spray signal is sent out and when the glue dot flies and attaches to the target surface. This l...
