Description

  The present invention relates to a component holder used when holding or transporting a thin plate-shaped electronic component or the like such as a silicon wafer or a flexible printed circuit board after processing.

  Conventionally, thin plate-like electronic components such as silicon wafers, flexible printed boards, glass plates and the like are easily damaged. Therefore, during the processing, they are fixed to a holder and subjected to processing such as polishing, patterning, and dicing. And in the electronic component in which a some process is performed in another place, it is moved in the state fixed to the holder also in the case of the conveyance of the electronic component between the processes. In other words, in such a component holder, the electronic components are fixed so that they do not move and overlap each other during processing and transportation, and can be easily removed during assembly work for incorporation into the electronic device body. It is required to be.

  Conventionally, as such a component holder, there is a type of holder in which a large number of convex bodies having the same height are formed on the surface of a base material, and electronic components are placed on the convex bodies and vacuum-sucked. (See Patent Document 1). In addition, there is a holder (see Patent Document 2) that is composed of an elastic member having a sticky surface and that holds the component in close contact with the surface of the elastic member by the adhesive force.

Among the conventional component holders as described above, vacuum suction type ones must always be kept in a suction state during processing, and the structure and manufacturing method of the holder itself are complicated and expensive.

When a part is placed, a part of the component comes into contact with the strong adhesive surface and is adhesively fixed at that position, so that the component can be held and fixed to the component holder with a sufficient holding force. In addition, when removing the parts, the upper part of the strong adhesive surface of the movable part is then changed to a position lower than the upper surface of the non-weak adhesive surface of the fixed part by the switching means. Because the strong adhesive surface is pulled away from the part and the part of the part that was not in contact with the strong adhesive surface is supported only by the non-weak adhesive surface of the fixed part, just lift the part from the component holder Can be removed easily. Therefore, since a large force that overcomes a large adhesive fixing force is not used when removing the component, the component is not accidentally applied to the component holder and damaged.
In addition, the movable part is composed of a rubber-like elastic body with a hollow part, and the position of the surface of the adhesive surface or the strong adhesive surface can be changed by discharging the air in the hollow part. Quick installation and removal operations can be realized with simple equipment that only connects devices.
Furthermore, the fixed part and the movable part are integrally formed of a rubber-like elastic body, and a hollow base part in which a part of the fixed part is cut out to form a movable part is a flat plate-like base material having rigidity. Since the position of the upper surface of the strong adhesive surface is changed by discharging the air in the cavity portion, the functional member composed of the movable portion and the fixed portion is made of an elastic synthetic resin. Since it can be integrally molded, it is possible to produce a large number of functional members with stable quality without variation in materials and dimensions, and the manufacturing cost of the component holder can be reduced. In addition, the fixed part and the movable part are fixed to a rigid flat base material, and the base material is provided with a vent hole communicating with the cavity part. Therefore, it is possible to follow a quick mounting / removing operation, and to deal with parts having different dimensional shapes.

According to the invention described in claim 3, in addition to the effects of the invention described in claims 1 and 2, when the air in the cavity (including the air in the sponge) is excluded from the vent hole, the cavity is deformed. As the sponge is crushed, it is elastically deformed so that when air flows into the cavity from the vent hole, the air is also taken into the sponge. Can quickly return to position. Thereby, since the cycle time of the process of carrying | maintaining or conveying after a process at the time of processing a thin-plate-shaped electronic component etc. can be shortened, the further improvement in production efficiency is attained.
