Description

Metal dome array plate manufacturing apparatus and method {MAKING MACHINE FOR METALDOME PLATE AND MAKING METHOD}

The present invention relates to an apparatus and method for manufacturing a metal dome array plate, and more particularly, a metal dome array that can be expected to improve productivity by performing all processes collectively by lining up process equipment for performing each process. Plate manufacturing apparatus and method.

In general, a communication device such as a mobile phone is provided with a key input means for inputting information or controlling the device. Such a key input means is made of a material such as rubber according to the trend that the communication device is lighter, smaller, and thinner. The metal dome array board is inserted between the keypad and the printed circuit board embedded in the device to turn on / off the contacts of the circuit.

Here, in the metal dome array plate, a transparent adhesive sheet is formed on the upper surface of the adhesive sheet in which a plurality of circular accommodating holes are formed in a constant arrangement, and the metal dome accommodated in the accommodating hole is fixed by the adhesive force of the transparent adhesive sheet. Before the installation on the printed circuit board embedded in the device, it is adhered to the release paper on the lower surface of the adhesive sheet, and the protective film is adhered to the lower surface of the release paper to prevent contamination of the metal dome. Is provided.

On the other hand, the conventional method for manufacturing a metal dome array plate adhesive sheet supplied in roll form as a plurality of accommodating holes and index holes in the state in which the release paper is bonded to the lower surface and the transparent adhesive sheet is bonded to the upper surface 1 step of cutting the LED lighting ball and the position hole, and cutting only the portion where the LED lighting ball is punched out, and arranging a plurality of the cut metal domes corresponding to the receiving holes. 2 steps of attaching and fixing to the receiving hole, 3 steps of cutting and separating unnecessary parts of the adhesive sheet (including the transparent adhesive sheet), and 4 attaching the protective film to the lower surface of the adhesive sheet to which the metal dome is fixed It consists of a process.

Alternatively, the adhesive sheet is unrolled from the roll by a predetermined interval to perforate the LED lighting ball, and a metal dome is attached to the accommodating hole of the adhesive sheet and then cut. After attaching is essentially a process of inspecting the adhesion state of the metal dome is performed.

However, conventionally, in performing the manufacturing process, the work of drilling the LED lighting ball and the position hole on the adhesive sheet is performed in the punching press, the cutting of the adhesive sheet is performed in the cutting machine, and unnecessary adhesive sheets are cut in the half-cutting machine. After removal by manual operation, the protective film is attached to the protective film roller by the protective film roller. Since it has to be transferred to the time loss is generated, and accordingly there is a problem that the productivity is lowered, there is a problem in that excessive labor is required because an operator is required for each equipment to be separated and operated.

On the other hand, attaching the ultra-small metal dome to the accommodating hole of the adhesive sheet is a vertical structure through a preliminary operation to be performed in a separate metal dome selector, the metal dome stacked in the storage rod as shown in Figure 1a installation block 1000 After moving to each of the plurality of insertion grooves 1100 formed in the metal dome 1200 accommodated in the insertion groove through a vacuum suction machine 2000 having a plurality of suction rods 2100 having a suction force is connected to a separate vacuum means While attached to the receiving hole 3100 of the adhesive sheet 3000 as shown in Figure 1b in a single suction state,

In performing such an attachment operation, the insertion hole 1100 in the process of sucking the metal dome 1200 accommodated in the insertion hole 1100 of the installation block 1000 in the suction rod 2100 of the vacuum inhaler 2000). As the static electricity is generated between the metal dome 1200 and the metal dome 1200 that are stacked and stored in the plurality of metal domes, the plurality of metal domes are sucked into the suction rod 2100 in a state of being stacked in a state of being adhered and fixed to the adhesive sheet 3000. Due to this, there is a problem that the failure rate rises,

In addition, the insertion hole 1100 of the installation block 1000 is formed as a diameter (5.2 mm) larger than the diameter (usually 5 mm) of the metal dome so that the metal dome 1200 accommodated therein can be easily drawn out. When the metal dome 1200 is adsorbed by the diameter difference and attached to the accommodating hole 3100 of the adhesive sheet 3000, the metal dome is not attached to the center of the accommodating hole. .

Thus, the present invention was devised to solve the general problems of the manufacturing method of the metal dome array plate manufactured through the separate process equipment as described above,

SUMMARY OF THE INVENTION An object of the present invention is to provide an apparatus and method for manufacturing a metal dome array plate which can expect productivity improvement effect by performing line-processing of each process to perform all processes collectively.

In another aspect, there is provided an apparatus and method for manufacturing a metal dome array plate which can improve productivity while minimizing a defect rate by improving a process equipment for bonding a metal dome to an adhesive sheet.
