Description

Measuring fixture

The invention relates to a jig, and in particular to a measuring jig.

In the nano-imprinting process, metal molds are usually used for imprinting. The metal mold includes a substrate and an embossed layer provided on the substrate, and the embossed layer has an embossed pattern, so that the embossed pattern can be transferred to the workpiece to be embossed through the pressing of the metal mold. Because the material of the workpiece is thin, if the operator directly separates the workpiece from the metal mold after the imprinting is completed, the workpiece may be broken. Therefore, the common practice is to separate the stamped workpiece from the metal mold with the aid of the mold release assembly.

Furthermore, the mold release assembly includes a mold release ring and a plurality of pushers. The mold release ring and pushers surround the periphery of the metal mold and the workpiece, but do not interfere with the stamping action of the metal mold and the workpiece. After the imprinting is completed, the pushing member pushed by the gas pushes the mold release ring to move toward the workpiece, so that the mold release ring further pushes the workpiece. In this way, the workpiece pushed by the mold release ring is gradually separated from the metal mold from the surrounding to the middle.

In this way, the mold release assembly 120 can be used in the nano-imprinting process (such as being installed on an imprinting machine (not shown)) and the auxiliary workpiece (not shown) is separated from the metal mold (not shown), And before or after the imprinting machine is installed, the mold release assembly 120 is measured and calibrated by the measuring jig 100.

Specifically, the mold release assembly 120 includes a mold release base 122, a mold release ring 124, and a plurality of pushers 126, wherein the mold release ring 124 and the pusher 126 are disposed on the mold release base 122, and the pusher 126 corresponds to the release模环124。 124 of the mold ring. The mold release ring 124 presents a circular ring shape, and the pushing members 126 are circumferentially arranged around the mold release ring 124. In particular, the push members 126 are distributed equally around the mold release ring 124 at equal intervals, and each push member 126 is inside 126a corresponds to the mold release ring 124, and the outer side 126b of each pushing member 126 corresponds to the air passage (not shown) on the mold release base 122. Furthermore, FIG. 2 disassembles the mold release base 122 into two combined parts 122a and 122b to show the mold release ring 124 and a plurality of pushers 126 assembled in the mold release base 122, but the mold release assembly 120 In fact, it can be used as an assembleable component (that is, there is no need to disassemble its internal components during the use of the mold release assembly 120), and then directly assembled to the imprinting machine as an auxiliary to separate the workpiece from the metal mold , Or directly assembled to the measuring jig 100 for measurement, and the present invention does not limit the specific embodiment of the mold release base 122, which can be various suitable shapes for setting the mold release ring 124 and the pushing member 126, so that It can be used as an assemblable component.

Furthermore, in the case where the mold release assembly 120 is assembled to the imprinting machine, the mold release base 122 is located on one side of the metal mold, so that the mold release ring 124 and the pushing member 126 surround the metal mold and the workpiece, but not Interfere with the stamping action of the metal mold and the workpiece. In this way, the metal mold assembled to the imprinting machine table can imprint the workpiece placed on the chuck, and after the imprinting is completed, the gas is provided through the inflatable component (not shown) on the imprinting machine table To the mold release assembly 120, the outer side 126b of each pusher 126 is pushed by the gas to move relative to the mold release base 122, and then the inner side 126a of each pusher 126 is pushed by the principle of the lever to the direction of the workpiece The movement causes the mold release ring 124 to further push the workpiece. In this way, the workpiece pushed by the mold release ring 124 gradually separates from the metal mold from the periphery to the middle.

Since the mold release assembly 120 is assembled on the stamping machine as an assembleable assembly, and the mold release base 122 is located on one side of the metal mold, the mold release ring 124 and the pushing member 126 surround the metal mold and the workpiece Therefore, when the metal mold needs to be replaced or the metal mold cleaned, the mold release assembly 120 also needs to be disassembled from the imprinting machine table. However, the action of disassembling the mold release assembly 120 may affect the level of the mold release ring 124, and the level of the mold release ring 124 will affect the result of the workpiece being separated from the metal mold. In this way, before reassembling the mold release assembly 120 onto the imprinting machine table, the level adjustment of the mold release assembly 120 (especially the mold release ring 124) is usually performed again. Even if the mold release assembly 120 is calibrated, the calibration result needs to be further measured to confirm whether the level of the mold release assembly 120 meets the requirements. Therefore, the mold release assembly 120 can be further measured using the measuring jig 100 described in this embodiment.

In this embodiment, the inflatable component 130 is disposed on the measurement base 110, the mold release component 120 and the measurement component 140 are detachably assembled on the measurement base 110, and the mold release component 120 is disposed on the measurement Between the base 110 and the measuring assembly 140. That is, the measuring jig 100 includes three parts as shown in FIG. 2, namely, the measuring base 110 and the inflatable component 130 disposed thereon, and the mold release component detachably assembled on the measuring base 110 120, and the measuring assembly 140 detachably assembled on the measuring base 110 and the mold release assembly 120. In this way, after the mold release assembly 120 is detached from the aforementioned imprinting machine, it can be directly installed on the measurement base 110 as an assembleable assembly (for example, a pair of rails 112 is provided on the measurement base 110 The mold release assembly 120 is slid in with the mold release base 122, but the invention is not limited thereto), and the mold release assembly 120 is further connected to the inflatable assembly 130. Then, the measuring assembly 140 is further disposed on the mold release assembly 120, so that the mold release assembly 120 is disposed between the measurement base 110 and the measurement assembly 140, and the mold release assembly 120 (especially the Mold ring 124).

In detail, in this embodiment, the inflation assembly 130 includes an inflation switch 132 and an inflation port 134. The inflation switch 132 is disposed on the measurement base 110 and electrically connected to the inflation port 134 to control whether to inflate (ie, provide gas) through the inflation port 134. In the case where the mold release assembly 120 is disposed on the measurement base 110, the inflation port 134 of the inflation assembly 130 corresponds to the mold release assembly 120, and in particular corresponds to the periphery of the pushing member 126. In this way, the inflation port 134 of the inflation assembly 130 can be used to inflate the periphery of the pushing member 126 so that the pushing member 126 pushes the mold release ring 124 to the reference position.

In this embodiment, the reference position refers to a position where the mold release ring 124 corresponds to the periphery of the workpiece and is located at a single level when the mold release assembly 120 is assembled to the imprinting machine table. After the mold release ring 124 is used to separate the workpiece from the metal mold, the mold release ring 124 is located at the operating position, and can be readjusted to the reference position through the measurement jig 100 and perform measurement calibration. Therefore, when the mold release assembly 120 is disposed on the measurement base 110, the inflation assembly 130 inflates to the mold release assembly 120, so that the pushing member 126 simultaneously pushes the mold release ring 124 to the reference position, thereby making the mold release ring 124 Adjust to a single level. That is, each pushing member 126 is moved by the gas of the inflation component 130 by the same amount, so that the position where the mold release ring 124 moves is the same. However, in the case where the part of the mold release ring 124 is at a different horizontal height relative to other parts, the gas amount corresponding to the part can be strengthened by the inflatable component 130 to adjust the horizontal height of the part to be the same as the other parts, The above embodiments can be adjusted according to requirements, and the invention is not limited thereto.

In addition, in the present embodiment, the measuring assembly 140 includes a rotating ring 142, a measuring member 144, and a seat body 146, wherein the rotating ring 142 is disposed on the seat body 146, and the measuring member 144 is disposed on the rotating ring 142. Furthermore, in this embodiment, three measuring elements 144 are used, such as dial gauges, which are distributed on the rotating ring 142 at equal intervals, but the number, arrangement positions and types of the measuring elements 144 can be adjusted according to requirements The present invention is not limited to this. In this way, the measuring assembly 140 as an assembly-type assembly is directly arranged on the mold release assembly 120 with the base body 146 (the base body 146 may further be provided with a handle 148 to facilitate the assembly of the measuring assembly 140, but this The invention is not limited to this), and then the measuring assembly 140 can be used to measure whether the mold release ring 124 is located at the reference position, for example, the measurement member 144 is sequentially measured by the rotating ring 142 relative to the mold release ring 124 to measure the mold release Multiple partial levels of the ring 124.

Specifically, the operation procedure of the measuring jig 100 is as follows. First, the mold release assembly 120 will be removed from the stamping machine table and set on the measurement base 110. The mold release ring 124 at this time has been used to separate the workpiece from the metal mold and is located at the operating position. Next, the mold release assembly 120 is connected to the inflatable assembly 130, and the measurement assembly 140 is disposed on the mold release assembly 120. Since the mold release base 122 of the mold release assembly 120 is originally provided with an inflation channel (not shown) in the imprinting machine table for passing gas to drive the pushing member and the mold release ring to push the workpiece away from the metal mold, Therefore, during the operation of the measuring jig 100, the inflation port 134 of the inflation assembly 130 can also be connected to the aforementioned inflation channel in the mold release assembly 120, and thus corresponds to the periphery of the pushing member 126. When all the above components have been assembled, the inflation switch 132 is pressed to inflate the mold release assembly 120 via the inflation port 134. Thereby, the pushing member 126 further pushes the mold release ring 124 by the pushing of the gas, so that the mold release ring 124 returns from the operating position to the reference position.

After the mold release ring 124 returns to the reference position, the corresponding local horizontal height of the mold release ring 124 is first measured by the measuring member 144 on the measuring assembly 140. After confirming that the value on the measuring element 144 meets the requirement, that is, the local level of the mold ring 124 corresponding to the measuring element 144 meets the requirement, move the rotating ring 142 so that the measuring element 144 is opposed by the rotating ring 142 As the release ring 124 rotates, it moves to the next part corresponding to the release ring 124. At this time, observe whether the measurement piece 144 has a numerical change. If there is, it means that this part of the mold release ring 124 is at a different horizontal height from the previous part, and the horizontal height adjustment needs to be performed again. If not, it means that the mold is released. This part of the ring 124 is at the same level as the previous part. By continuously moving the rotating ring 142 in this way, the measuring piece 144 sequentially measures the horizontal heights of a plurality of parts on the mold release ring 124, thereby knowing whether the whole of the mold release ring 124 is located at the same horizontal height, that is, the distance Whether the mold ring 124 is accurately positioned at the reference position.

When the level of the mold release ring 124 needs to be adjusted again, for example, the aforementioned action of pushing the mold release ring 124 through the inflatable component 130 to push the mold release ring 124 can be performed again, and then the aforementioned measurement by the measuring component 140 can be performed again. The action of the release ring 124. In addition, after confirming that the mold release ring 124 is accurately positioned at the reference position, first the measurement assembly 140 is removed from the mold release assembly 120, and then the mold release assembly 120 is removed from the measurement base 110. Since the measurement assembly 140 and the mold release assembly 120 are each used as an assembleable assembly, assembly and disassembly of the measurement assembly 140 and the mold release assembly 120 become easy. After adjustment and calibration, the mold release assembly 120 can be reassembled into the imprinting machine and used again in the imprinting process to assist in separating the imprinted workpiece from the metal mold.

In summary, in the measuring jig of the present invention, the mold release component is provided on the measurement base, the inflatable component is provided on the measurement base, and the measurement component is provided on the mold release component. Among them, the mold release ring of the mold release assembly is used in the imprinting machine to separate the workpiece from the metal mold to be in the operating position. In this way, when the mold release assembly is installed on the measurement base and connected to the inflation assembly and the measurement assembly, the inflation assembly inflates to the mold release assembly, so that the pusher pushes the mold release ring to the reference position, and then measures The component measures whether the mold release ring is at the reference position. In this way, the mold release ring can be restored to the reference position again and used again in the stamping press table. Accordingly, the measuring jig provided by the present invention can be used to measure the level of the mold release assembly, so that the mold release assembly has accurate calibration results.

Although the present invention has been disclosed as above with examples, it is not intended to limit the present invention. Any person with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention.
