Description

Carrier Stacker

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a carrier stack for use in a multi-mix mixed-print board assembly production system. More particularly, the present invention relates to a carrier stacking apparatus capable of aligning and stacking a plurality of carriers for carrying and fixing a printed circuit board.

Typically, factory automated assembly systems use conveyor belts to assemble printed circuit boards for electronic devices, either manually or automatically into the printed circuit board, depending on the work process. It is a system for assembling after soldering.

As the technology changes rapidly in recent years, the life cycle of products is shortened, and it is necessary to produce products that meet the needs of consumers who prefer high-quality and low-priced products. The production cost must be reduced. In order to reduce the production cost, the productivity must be improved by simplifying the manufacturing process or reducing the man-hour. To this end, it must be able to smooth the flow of logistics and completely eliminate the loss of workers.

1 is a configuration diagram schematically showing a process of a conventional assembly system of a printed circuit board.

As shown in FIG. 1, the operator places the printed circuit board on the conveyor belt and sequentially inserts the corresponding parts indicated in the component insertion guide while the printed circuit board moves slowly. Many workers insert only the parts assigned to the individual to the printed circuit board, then turn over to the next worker with the conveyor belt, and the next worker inserts their assigned parts into the printed circuit board transferred to the conveyor belt. In this way, a plurality of workers insert only the parts assigned to them among the various parts, and then pass the conveyor belt to the next worker to complete the assembly work. When the parts are inserted into the printed circuit board by a plurality of workers, they are transferred through the conveyor belt to the spray flux. In the spray flux, the flux is automatically applied to the transferred printed circuit board and transferred to the soldering apparatus. The soldering apparatus transfers the solder by soldering the printed circuit board coated with the flux from the spray flux. The printed circuit board transferred through the soldering apparatus is cooled by a cooling fan. After soldering, the cooled printed circuit board is cut by the operator using a cutting device. When the cutting is completed, it is passed to the next worker, the next worker uses the component insertion internal circuit tester equipment to check the capacity of the part, short of the pattern, open or the like. This operation is repeated to assemble the printed circuit board.

However, the printed circuit board assembling system that proceeds through the flow process as described above is able to produce only one product, so every time the item of the product is changed, take out all the parts loaded in the parts container, and then Prepare the production line according to the new product change by loading parts, attaching new parts insertion instructions, adjusting the conveyor belt to the changed printed circuit board size, and training the workers according to the new work. During this time, a number of workers rested, resulting in a problem of waste of manpower and productivity.

A method for solving such a problem is disclosed in detail in 'Multiple mixed-flow print board assembly production system and method thereof' filed November 25, 1996.

Such a system is a system capable of assembling various types of printed circuit boards (different horizontal and vertical sizes of printed circuit boards respectively) into one production line. The operation of the system will be described as follows.

Multi-mix mixed-circuit board assembly production system is assembled by each cell at the same time according to the component insertion instruction information using computer to multi-type printed circuit board and transferred through the first conveyor of the workbench, spray flux through the first conveyor line And pass through the soldering device. Subsequently, the carrier on which the soldered printed circuit board is fixed is transferred to the second conveyor by the elevator, and the transferred carrier is transferred to the second conveyor of each work platform through the second conveyor line. This is followed by a process of returning to each corresponding cell by the lifter.

In order to fix and move the multi-type printed circuit board to be used until it is placed on the first conveyor of each workbench and then returned to the second conveyor of the workbench and inspected, the printed circuit board and the Multiple carriers are used together. However, when using a plurality of carriers in the workbench, the carriers are stacked around the workbench, which may cause confusion in the work of workers and risk of breakage. In addition, when carrying the carrier, there is a problem that the inconvenience that the workers carry directly.

As described above, a plurality of carriers are required in each cell, and accordingly, there is a need for a device for loading or moving a plurality of carriers in proper alignment. In order to realize this need, a carrier loading device of the present invention has been required.

SUMMARY OF THE INVENTION An object of the present invention is to provide a carrier stacking device for stacking a plurality of carriers used in a workbench of each cell in a multi-mix mixed-print board assembly production system process.

In order to achieve the above object, the present invention is characterized in that a plurality of separation plates in the longitudinal direction of at least one mounting box can be configured in the longitudinal direction, and the carrier can be carried by mounting the mounting holes formed by the separation plate.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is to provide a carrier stacking device for stacking a plurality of carriers used in order to secure a printed circuit board of various sizes in the workbench of each cell in a multi-mix mixed-print board assembly production process.

As shown in FIG. 2 or FIG. 4, the main configuration of the present invention includes at least one or more mounting boxes 12 in a longitudinal direction in order to load a plurality of carriers 22 capable of attaching and detaching various sized printed circuit boards. Configure. The mounting box 12 is composed of a plurality of separation plates 14 so that the carrier mounting holes 16 are formed at regular intervals. The separator 14 is also configured in the longitudinal direction. And the separation plate 16 is cut in a trapezoidal shape in each direction in order to facilitate the attachment and detachment of the carrier 22. In addition, in order to facilitate the movement of the carrier stacking device 10, a carrying handle 18 is installed on the opposite side of the mounting opening 16 of the carrier stacking device 10, and a moving wheel is provided below the carrier stacking device 10. Install (20).

The carrier stacking device 10 prevents damage to the carrier 22 when the carrier is attached or detached, and forms a material of wood for a smooth sliding action.

The main action of the present invention configured as described above is that when the carrier 22 is mounted on the mounting hole 16 formed by the separating plate 14 of the mounting box 12, the carrier loading device 10 is made of wood Because of this, it can be mounted with a smooth sliding action, and the separation plate 14 is trapped in a trapezoidal shape even when the carrier 22 is separated from the stacking device 10, so that each carrier 22 can be grasped and separated. Is easy. In addition, when the carrier stacking device 10 needs to be moved, the carrier handle 18 installed at the rear of the mounting hole 16 of the stacking device is held and moved by the moving wheel 20 installed at the lower side. It is easy to

As described above, in the multi-stream mixed-flow printed circuit board assembly production system according to the embodiment of the present invention, a carrier stacking device for stacking a plurality of carriers for fixing printed circuit boards of various sizes may properly align the plurality of carriers. Since it is loaded so as to remove the confusion of the worker due to the carrier, to clean the operator environment, and easy to move there is an effect to improve the productivity of the product accordingly.
