Description

Opening device

The present invention relates to an opening device.

A drilling device is known in which a hole is made in a workpiece such as a printed circuit board by a drill. For example, Patent Document 1 describes a drilling device including a platform, a spindle, and a pressing device that can rotate and lift while holding a tool for processing a printed circuit board placed on the platform. The pressing device is used when processing a printed circuit board. , Push the printed substrate to the platform.

As a hole-opening device, there is a person who performs a hole-drilling process in a state where a workpiece is pushed from the opposite side of the drill to the drill side by a receiving member. The bearing member is used to make a hole with a workpiece by a drill during the first use. In the hole of the receiving member that has been chiseled at the first use, the drill bit is inserted when the second and subsequent hole processing is performed.

However, in the above-mentioned conventional technology, the drill bit is repeatedly inserted into the hole of the receiving member by a hole-cutting process, because the drill bit is slightly shaken, the hole diameter of the receiving member is gradually enlarged. Once the hole diameter of the receiving member is enlarged, a gap is generated between the hole of the receiving member and the drill when the workpiece is opened. When the drill penetrates the workpiece, the gap between the hole of the receiving member and the drill is a part of the material constituting the workpiece will be extruded. Therefore, a burr is generated in the opening edge of the hole formed in the workpiece so as to protrude toward the receiving member side.

Therefore, a hole-opening device for sandwiching a thin plate-shaped intervening member between a receiving member and a workpiece during the opening of a workpiece has been developed. In this device, the interposing member is formed into a band shape, and is held in a state of being wound around a reel, for example. Then, the unused part of the intermediate member pulled out from the reel is sandwiched between the receiving member and the workpiece for each opening process. According to the opening method using this device, the opening edge on the receiving member side of the workpiece can be covered by the intermediate member. Thereby, when the drill penetrates the workpiece, the material constituting the workpiece will come into contact with the intermediary member, which can prevent extrusion from the opening edge of the receiving member side of the workpiece to the gap between the hole of the receiving member and the drill. Therefore, it is possible to suppress the occurrence of burrs at the opening edge of the workpiece receiving member when the workpiece is opened.

However, the receiving member approaches the workpiece and presses the workpiece when the hole is opened, and moves away from the workpiece after the hole is opened. In a separate position from the bearing member When installing the reel, the intermediate member will be dragged when the bearing member approaches the workpiece, so the intermediate member must be released from the reel one after another. When the receiving member is separated from the workpiece, the intermediate member must be wound on a reel. As such, the reel must be operated whenever the receiving member approaches and leaves the workpiece. Therefore, by installing the reel at a position interlocking with the movement of the receiving member, it is possible to suppress the intermediate member from being dragged to the operating receiving member, and the reel operation is not required.

However, in order to drill holes with different hole diameters, when the hole opening device has a plurality of drill bits and a plurality of receiving members corresponding to the respective drill bits, if a reel is installed at a position interlocking with the operation of each receiving member, Since a plurality of reels are arranged in a limited space, the reels are compact. As a result, the intermediary member wound around each reel becomes short. Therefore, in order to replace the reel, it is necessary to frequently cut the hole, and there is a problem that the manufacturing efficiency is reduced. In addition, if a plurality of reels are arranged for a plurality of drills, the cost of the apparatus increases.

Therefore, the present invention is to provide a drilling device having a plurality of drill bits and a plurality of receiving members, while suppressing a decrease in manufacturing efficiency and suppressing an increase in the cost of the device.

Therefore, reduction in manufacturing efficiency can be suppressed. In addition, since the intervening members are supplied to a plurality of drill bits from one intervening member supplying unit, an increase in the cost of the device can be suppressed.

In addition, because the intermediary member supply section holding the intermediary member is relatively Since the body is fixed, the transport path of the intermediate member drawn from the intermediate member supply unit can be set along the surface of the workpiece. Thereby, when each receiving member moves close to the workpiece, the distance of the intermediate member being dragged to the moving receiving member can be reduced. As a result, the operation of the intermediate member supply unit can be minimized.

In the above-mentioned hole-opening device, it is preferable that the workpiece is placed on an upper workpiece platform, and the intermediary member supply unit is provided above the workpiece platform.

According to the present invention, since the intermediary member supply section is provided on the side where the workpiece is placed on the workpiece, it can be compared with the configuration in which the intermediary member supply section is provided on the lower side of the workpiece platform, and it is possible to surround the intermediate member supply section Expand the space for securing. Therefore, it is possible to expand the formation of the intermediate member supply portion, and it is possible to hold more intermediate members in the intermediate member supply portion. In addition, the working space can be enlarged and secured around the intermediate member supply section, and the work around the intermediate member supply section can be performed efficiently. Therefore, for example, it is possible to shorten the processing time of the intermediate hole due to the replacement of the intermediate member. Therefore, reduction in manufacturing efficiency can be suppressed.

In the above-mentioned opening device, it is preferable that the intermediary member supply unit is provided with a damper that imparts rotational resistance to the reel.

According to the present invention, when the unused intermediate member is pulled out from the reel, the reel can be prevented from idling and the intermediate member can be relaxed.

According to the present invention, it is because it is sandwiched between the first receiving member and the workpiece when opening the workpiece by the first drill, and is sandwiched between the second receiving member and the workpiece when opening the workpiece by the second drill. As compared with the configuration in which the intermediate member supply section is installed for each receiving member, the intermediate member supply section can be expanded and the intermediate member can be held in the intermediate member supply section more than the configuration in which the intermediate member supply section is installed for each receiving member. Therefore, reduction in manufacturing efficiency can be suppressed. In addition, since the intervening members are supplied to a plurality of drill bits from one intervening member supplying unit, an increase in the cost of the device can be suppressed.
