The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

A multi-station operation dispenser 1000 according to an embodiment of the present invention will be described first in detail with reference to the accompanying drawings.

As shown in fig. 1 to 11, a multi-station operation dispenser 1000 according to an embodiment of the present invention includes: at least two conveyor assemblies and a working mechanism, the working mechanism being located above the conveyor assemblies (not shown in the figures).

Specifically, each conveying assembly is provided with a working area, the working mechanism can move to the working area of any one conveying assembly and perform repeated work on the workpieces placed in the working area at least twice, the preset working waiting time is kept between the repeated work and the work waiting time, the working mechanism is arranged in the working area of one conveying assembly, and when the working mechanism performs one work on the workpieces placed in the working area and is in the working waiting time for performing the next work, the working mechanism moves to the other working area of the other conveying assembly and performs work on the workpieces placed in the other working area.

In other words, the multi-station operation dispenser 1000 according to the embodiment of the present invention is mainly composed of at least two conveying assemblies and an operation mechanism. The present embodiment takes two conveying assemblies as an example, and is hereinafter referred to as a first conveying assembly 100 and a second conveying assembly 200. The first conveying assembly 100 and the second conveying assembly 200 are provided with operation areas. The operation area can be designed into one or more according to the process requirement, and the embodiment takes one operation area as an example. The workpiece may be transferred to the working area waiting work, at which time the first work may be performed on the workpiece a of the working area of the first conveyor assembly 100 by the working mechanism. After the operation mechanism finishes the first operation on the workpiece A, the workpiece A needs to pass through the preset operation waiting time, and after the preset operation waiting time is finished, the operation mechanism executes the second operation on the workpiece A. Wherein: during the period that the workpiece a enters the operation waiting time, the operation mechanism can move to the second conveying assembly 200 to operate the workpiece B in the operation area of the second conveying assembly 200, and the operation flow of the workpiece B is consistent with that of the workpiece a.

The invention is applicable to specific processes, such as: one workpiece (workpiece a or workpiece B) needs to perform multiple operations, and after each operation, a certain time needs to be waited, and after the glue flows sufficiently or other processes are completed, the next operation is performed. The preset job waiting time can be set according to the actual process, and when the job waiting time is longer, the time (namely, the longer job waiting time, which is calculated by minutes) can be used for another conveying assembly to operate, so that the efficiency is improved. Alternatively, if the preset operation waiting time is less than or equal to the operation time of the operation mechanism, the operation mechanism may transfer to the first conveyor assembly 100 immediately after performing the first operation on the workpiece B of the second conveyor assembly 200, and perform the second operation on the workpiece a on the operation area of the first conveyor assembly 100. If the preset operation waiting time is longer than the operation time of the operation mechanism, the operation mechanism waits after the operation is performed on the second conveying assembly 200 until the preset operation waiting time is over, and performs a second operation on the workpiece a on the operation area of the first conveying assembly 100, or a third conveying assembly is arranged, and the operation mechanism moves to the operation area of the third conveying assembly to perform an operation on the corresponding workpiece C. If the preset operation waiting time is less than or equal to the two-time operation time of the operation mechanism, the operation mechanism can immediately turn to the first conveying component 100 after operating the third conveying component, and perform the second operation on the workpiece a on the operation area of the first conveying component 100, and so on, and a more appropriate operation mode can be further adopted according to the operation time of the operation mechanism and the operation waiting time between two-time operation on the workpiece, so as to achieve the maximum balance between the operation time and the operation waiting time, and further improve the working efficiency.

The preset operation waiting time may be a time required to wait for the glue to flow sufficiently or be generated by performing other process steps, and is not limited herein.

In addition, the multi-station operation dispenser 1000 according to the embodiment of the present invention can be applied to other various working conditions, and as long as the operation environment requires multiple operations and requires "waiting for a period" between any two operations, the problem can be solved by the operation principle of the multi-station operation dispenser 1000 of the present invention.

Therefore, according to the multi-station operation dispenser 1000 provided by the embodiment of the invention, the operation waiting time can be fully utilized, and the number of the conveying assemblies can be optimized according to the operation time of the operation mechanism and the operation waiting time between two times of processing of the workpiece, so that the maximum balance between the operation time and the operation waiting time is achieved, and the working efficiency is further increased.

According to one embodiment of the present invention, the working time of the working mechanism at any one time is greater than or equal to the working waiting time. When the operation time of the operation mechanism at any time is more than or equal to the operation waiting time, the operation mechanism can move to another conveying assembly to operate the workpiece on the other conveying assembly after the current operation is finished. It should be noted that the operation mechanism repeats the operation for a plurality of times, wherein the time of each operation is the same or different, and can be set according to the process requirement.

In some embodiments of the invention, each conveyor assembly comprises a first conveyor unit 26, a second conveyor unit 27 and a third conveyor unit 28, which are independent of each other and arranged in succession in the conveying direction.

That is, the working mechanism may be in a state of waiting for the glue to flow sufficiently or for the next process step to be performed in a state of a preset working waiting time, which is not limited herein. Therefore, the operation mechanism can move to the other conveying component and operate the workpieces on the other conveying component in the waiting period, so that the waiting period of the operation mechanism in an idle state can be effectively utilized, and the operation efficiency is improved.

According to one embodiment of the invention, when the operation mechanism moves to the other conveying component and performs operation on the workpiece on the other conveying component, the operation waiting time of the current workpiece is required to be met.
