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

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

Specifically, each conveying component is provided with a working area, the working mechanism can move to the working area of any conveying component and execute at least twice repeated operation on a workpiece placed in the working area, a preset operation waiting time is kept between the two repeated operation, and when the working mechanism is in the working area of one conveying component and executes one operation on the workpiece placed in the working area and is in the operation waiting time for executing the next operation, the working mechanism moves to the other working area of the other conveying component and executes the operation on the workpiece placed in the other working area.

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

The invention is applicable to some special processes, such as: one work piece (work piece a or work piece B) needs to be performed a plurality of times, and after each work, a certain period of time needs to be waited for, and after the glue is sufficiently flowed or other working procedures are completed, the next work is performed. The preset job waiting time can be set according to the actual process, and when the job waiting time is long, the time (namely, the long job waiting time is calculated in minutes) can be utilized to carry out another conveying component job, so that the efficiency is improved. Alternatively, if the preset job waiting time is less than or equal to the job time of the job mechanism, the job mechanism may immediately transfer to the first conveying assembly 100 after performing the first job on the workpiece B of the second conveying assembly 200, and perform the second job on the workpiece a on the working area of the first conveying assembly 100. If the preset job waiting time is longer than the job time of the job mechanism, the job mechanism waits after working on the second conveying assembly 200 until the preset job waiting time is over, and then works on the workpiece a on the working area of the first conveying assembly 100 for the second time, or sets a third conveying assembly, and the job mechanism moves to the working area of the third conveying assembly to work on the corresponding workpiece C. If the preset operation waiting time is less than or equal to the two operation time of the operation mechanism, the operation mechanism can immediately transfer to the first conveying assembly 100 after operating the third conveying assembly, and the second operation is performed on the workpiece A on the operation area of the first conveying assembly 100, so that a more proper operation mode can be adopted according to the operation time of the operation mechanism and the operation waiting time between the two operations on the workpiece, so that the balance between the operation time and the operation waiting time which are the largest is achieved, and the working efficiency is further improved.

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

In addition, the multi-station operation dispensing machine 1000 according to the embodiment of the invention can be applied to other various working conditions, and the corresponding problem can be solved by the operation principle of the multi-station operation dispensing machine 1000 as long as the multi-station operation dispensing machine is required to perform multiple operations and a period of waiting time is required between any two operations.

Therefore, according to the multi-station operation dispensing machine 1000 of the embodiment of the invention, not only the operation waiting time can be fully utilized, but also the number of conveying components can be optimally set 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 balance between the operation time and the operation waiting time is maximum, and the working efficiency is further increased.

According to one embodiment of the present invention, the job time of any one time of the job mechanism is greater than or equal to the job waiting time. The working time of the working mechanism at any time is larger than or equal to the working waiting time, and the working mechanism can move to the other conveying assembly to work the workpiece on the other conveying assembly after the current working is finished. It should be noted that, the operation mechanism repeatedly performs operations for multiple times, where the time of each operation is the same or different, and may be set according to the process requirement.

In some embodiments of the present invention, each of the conveying assemblies includes a first conveying unit 26, a second conveying unit 27, and a third conveying unit 28, which are independent of each other and are sequentially disposed in a conveying direction. The workpiece is moved sequentially along the first conveying unit 26, the second conveying unit 27, and the third conveying unit 28. The work area corresponds to the second conveying unit 27, and the work mechanism performs a work on the workpiece moved to the second conveying unit 27.

That is, the working mechanism may be in a state where it is required to wait for the glue to sufficiently flow or to perform the next process step in a state of a preset working waiting time, which is not limited herein. Therefore, the working mechanism can move to the other conveying assembly and work the workpiece on the other conveying assembly in the waiting period, so that the waiting period of the working mechanism in an idle state can be effectively utilized, and the working efficiency is improved.

After the heating is completed, the conveying rail 20 is in a rising state, and the workpieces and the corresponding heating platforms 30 are distributed at intervals. That is, after the tray 500 is conveyed by the material taking mechanism to the position above the corresponding heating platform 30 of the first conveying unit 26, the corresponding lifting mechanism 40 can drive the conveying track 20 of the first conveying unit 26 to drive the workpiece 500 to move downward until the heating module can heat the workpiece. After the heating is finished, the lifting mechanism 40 drives the conveying track 20 of the first conveying unit 26 to drive the workpieces 500 to move upwards, at this time, the heating platforms 30 are kept different, the conveying track 20 of the first conveying unit 26 is in an ascending trend and is distributed with the heating platforms 30 at intervals, the material tray 500 can continue to move to the second conveying unit 27 and the third conveying unit 28, and the working principle of the lifting mechanism 40 corresponding to the second conveying unit 27 and the third conveying unit 28 is the same.

In summary, the operation method of the multi-station operation dispenser 1000 according to the embodiment of the invention can perform multi-stage heating, for example, the multi-stage heating is divided into a preheating stage, a dispensing stage and a heat preservation stage, which can further improve the dispensing effect and the dispensing efficiency, and by adopting the manner that the conveying rail 20 is lifted and the heating platform 30 is stationary, the problem that more wires and air pipes are assembled on a working platform with a conventional structure in the prior art can be overcome, and when the working platform moves up and down at high frequency, the wires and the air pipes are easily worn and scratched, and the maintenance is inconvenient.
