[0032] The present invention provides a positioning tooling.

[0033] In the embodiments of the present invention, as Figure 1 shown, the positioning tooling includes a tray 100, a plurality of fixed positioning members 200, a plurality of movable positioning members 300, and a pressing assembly 400; the tray 100 has a supporting surface 121 for supporting the member to be supported; the fixed positioning members 200 are fixedly arranged on the tray 100 for limiting one side surface of the member to be supported; the movable positioning members 300 are movably arranged on the tray 100, and at least one movable positioning member 300 is arranged opposite to a fixed positioning member 200. The movable positioning member 300 has a first avoidance state in which it can avoid the member to be supported and be installed on the supporting surface 121, and a clamping state for clamping the other side surface opposite to the member to be supported.

[0034] The supporting surface 121 on the tray 100 is used to support the item to be supported, which can be a template used for nanoimprinting of wafers, or other items that are easily damaged and need to be frequently picked up, placed, and transported. When the item to be supported is placed on the supporting surface 121, the supporting surface 121 can support one surface of the item to be supported. Usually, the bottom surface of the item to be supported is in contact with the supporting surface 121. In the nanoimprinting process, if this positioning tooling is used to support and position the template, the supporting surface 121 can be annularly arranged, such as circular or rectangular annular, etc., so that the tray 100 has an avoidance hole that can be opposite to the effective imprinting area of the template, so that when the template is placed on this positioning tooling, it will not affect its imprinting function.

[0035] The positioning tooling in the present invention further includes a plurality of fixed positioning members 200 and a plurality of movable positioning members 300. The fixed positioning members 200 are fixedly arranged on the tray 100. Thus, when the item to be supported is placed on the supporting surface 121, one side of the item to be supported can be abutted against the fixed positioning members 200, so that the fixed positioning members 200 can limit one side surface of the item to be supported and reduce the risk of the item to be supported moving in the direction of the fixed positioning members 200. The movable positioning members 300 are movably arranged on the tray 100, and at least one movable positioning member 300 is arranged opposite to a fixed positioning member 200. Then, when the user places the item to be supported on the supporting surface 121 of the tray 100 and one side of it abuts against the fixed positioning members 200, the user can drive the movable positioning members 300 to move so that the side of the item to be supported away from the fixed positioning members 200 can be placed on the supporting surface 121. After the item to be supported is stably placed on the supporting surface 121, the user can release the movable positioning members 300 or drive the movable positioning members 300 to limit and hold the other side surface opposite to the item to be supported. Among them, the number of fixed positioning members 200 can be one, two, three, or four, etc., and the number of movable positioning members 300 can also be one, two, three, or four, etc. For the convenience of placing the item to be supported, a plurality of positioning blocks can be arranged adjacent to each other and are all located on one side of the item to be supported, while a plurality of movable positioning members 300 are arranged adjacent to each other and are all located on the other side of the item to be supported.

[0036] The technical solution of the present invention is to provide a positioning tooling. The positioning tooling includes a tray 100, and the tray 100 has a supporting surface 121 for placing the component to be supported. The positioning tooling further includes a plurality of fixed positioning members 200 and a plurality of movable positioning members 300. The plurality of movable positioning members 300 and the plurality of fixed positioning members 200 respectively clamp opposite side surfaces of the component to be supported, so that the component to be supported can be stably placed on the positioning tooling. When the user picks up, places or transports the component to be supported, the user can hold the positioning tooling to pick up, place or transport it, so as to achieve the effect of picking up, placing or transporting the component to be supported. In this way, it is possible to reduce the situation that the user directly contacts the component to be supported and contaminates or damages the component to be supported. In addition, by providing the movable positioning member 300, it can be movably arranged on the tray 100, and the movable positioning member 300 has a first avoidance state. When the movable positioning member 300 is in the first avoidance state, the component to be supported can be smoothly placed on the supporting surface 121 of the tray 100, avoiding interference between the component to be supported and the movable positioning member 300 during the placement process.

[0037] Specifically, the movable positioning member 300 can rotate relative to the tray 100 or slide relative to the tray 100.

[0038] In one embodiment, when the movable positioning member 300 rotates relative to the tray 100, threaded holes can be provided on the tray 100. The movable positioning member 300 includes a stud and an elastic rubber block fixedly provided on one side of the stud. During the process of the stud rotating and screwing into the threaded hole, the elastic rubber block on the stud has an avoidance state where it does not abut against the component to be supported. At this time, the component to be supported can be placed on the supporting surface 121 of the tray 100. When the stud is further tightened, the elastic rubber block abuts against the side of the component to be supported away from the fixed positioning member 200, so as to achieve the clamping state where the movable positioning member 300 clamps the opposite side surface of the component to be supported. At this time, the movable positioning member 300 is relatively stable when clamping the component to be supported.

[0039] In another embodiment, as Figure 1 shown, the movable positioning member 300 is slidably arranged on the tray 100, and the movable positioning member 300 can move away from the component to be supported to have a first avoidance state; or, the movable positioning member 300 can move towards the component to be supported to have a clamping state.

[0040] When the movable positioning member 300 slides relative to the tray 100, the movable positioning member 300 can be magnetically connected to the tray 100, so that the movable positioning member 300 can also move away from the fixed positioning member 200 under the drive of the user to provide an avoidance space for the to-be-supported member to be placed on the tray 100; and when the user releases the movable positioning member 300, it returns to its original position under the magnetic attraction of the tray 100 to clamp the to-be-supported member. Alternatively, a spring can also be provided between the movable positioning member 300 and the tray 100, and the extending direction of the spring is the direction in which the movable positioning member 300 faces away from the to-be-supported member. In the natural state of the spring, the movable positioning member 300 can clamp the side surface of the to-be-supported member. When it is necessary to avoid the to-be-supported member being placed on the support surface 121, the movable positioning member 300 moves away from the fixed positioning member 200, and at this time the spring is compressed, so that the spring is subjected to a compression force; after the to-be-supported member is placed on the support surface 121, the movable positioning member 300 is released, and then the movable positioning member 300 returns to its position under the elastic force of the spring to clamp the side of the to-be-supported member away from the fixed positioning member 200.

[0041] When the movable positioning member 300 slides relative to the tray 100, it is convenient for the user to drive at least two movable positioning members 300 together to make them in the first avoidance state, so as to provide sufficient avoidance space for the to-be-supported member to be placed on the support surface 121 of the tray 100.

[0042] Based on the solution that the movable positioning member 300 is slidably arranged on the tray 100, further, a positioning groove is provided on the tray 100. The positioning groove has a limiting groove wall away from the to-be-supported member. The movable positioning member 300 is installed in the positioning groove and can move in the positioning groove towards the limiting groove wall or away from the limiting groove wall.

[0043] By installing the movable positioning member 300 in the positioning groove of the tray 100, and the positioning groove has a limiting groove wall away from the to-be-supported member, when the user drives the movable positioning member 300 to move away from the fixed positioning member 200, it can be blocked by the limiting groove wall, so that the movable positioning member 300 has a definite maximum stroke, avoiding the situation of excessive movement stroke and coming out of the tray 100.

[0044] Based on the solution that the movable positioning member 300 is slidably arranged on the tray 100, further, as Figure 1 and Figure 3 shown, a first magnetic member 500 is provided on the surface of the tray 100 for connecting the positioning block, and a second magnetic member is correspondingly provided on the movable positioning member 300. The first magnetic member 500 and the second magnetic member are magnetically matched to make the movable positioning member 300 in a clamped state.

[0045] By providing a first magnetic member 500 on the surface of the tray 100 for connecting the positioning block, a second magnetic member is provided on the movable positioning member 300, and the first magnetic member 500 and the second magnetic member are magnetically coupled, the movable positioning member 300 has an initial position magnetically coupled with the tray 100. At this position, the movable positioning member 300 can hold the member to be supported, and the state of the movable positioning member 300 at this time is the above-mentioned holding state. When the user overcomes the magnetic attraction between the first magnetic member 500 and the second magnetic member, the movable positioning member 300 can be directly removed from the tray 100, or the movable positioning member 300 can be slid to misalign the first magnetic member 500 and the second magnetic member, so as to provide sufficient clearance space for the member to be supported to be installed on the support surface 121. It can be understood that when the tray 100 and the movable positioning member 300 are respectively provided with the first magnetic member 500 and the second magnetic member, on the one hand, the effect that the tray 100 can be connected to the movable positioning member 300 can be achieved, and on the other hand, when the movable positioning member 300 moves relative to the tray 100 to misalign the first magnetic member 500 and the second magnetic member, when the user releases the movable positioning member 300, the movable positioning member 300 will automatically return to its position under the mutual attraction of the first magnetic member 500 and the second magnetic member, so as to achieve the effect of automatically holding the member to be supported.

[0046] Of course, as Figure 1 and Figure 3 shown, a third magnetic member 600 can be provided on the tray 100, and a fourth magnetic member is provided on the fixed positioning member 200, and the third magnetic member 600 and the fourth magnetic member are magnetically coupled.

[0047] When the tray 100 and the fixed positioning member 200 are detachably connected, by providing a third magnetic member 600 on the tray 100 and a fourth magnetic member on the fixed positioning member 200, when the fixed positioning member 200 is not fixedly connected to the tray 100, their connection can be realized through the mutual attraction of the third magnetic member 600 and the fourth magnetic member, and at this time the fixed positioning member 200 can move relative to the tray 100, so that the fixed positioning member 200 has the function of the above-mentioned movable positioning member 300, so that when at least one of the movable positioning members 300 fails and cannot move, the fixed positioning member 200 can be used as the movable positioning member 300.

[0048] In an embodiment, as Figure 1 and Figure 5 shown, an alignment groove 310 is provided on the surface of a fixed positioning member 200 or a movable positioning member 300 for clamping the member to be supported.

[0049] It is understandable that, in the process of nanoimprinting a wafer, the edge of the template used therein usually has a notch (usually a notch) as a mounting reference when the template is mounted on the equipment. By providing an alignment groove 310 on the surface of the fixed positioning member 200 or the movable positioning member 300 for clamping the supported member, the notch of the template (i.e., the supported member) can be aligned with the alignment groove 310, so that different users can install the template on the positioning tooling in the same direction, thereby further ensuring the accuracy of the imprinting.

[0050] Further, please refer to Figure 1 and Figure 2 The positioning tool also includes a clamping assembly 400, which is rotatably disposed on the tray 100 and has a second avoidance state for avoiding the installation of the supported component on the support surface 121 and a clamping state for clamping the side of the supported component away from the support surface 121.

[0051] By setting up a clamping assembly 400, and the clamping assembly 400 has a clamping state of clamping the side of the part to be supported away from the supporting surface 121, the positioning stability of the part to be supported is further improved, thereby further reducing the risk of the part to be supported easily falling off the positioning tool when the user transports the part to be supported with the positioning tool.

[0052] In addition, the clamping assembly 400 is rotatably disposed on the tray 100, so that the clamping assembly 400 also has a second avoidance state, which is beneficial for pre-rotating the clamping assembly 400 to the second avoidance state when placing the supported member on the support surface 121 to avoid the installation of the supported member.

[0053] In one embodiment, please refer to Figure 1 and Figure 2 The pressing assembly 400 includes a fixed shaft 410 and a rotating pressing rod 420. The fixed shaft 410 is fixedly connected to the tray 100; the rotating pressing rod 420 is sleeved outside the fixed shaft 410 and can rotate around the fixed shaft 410 to press the upper surface of the supported member.

[0054] When the fixed shaft 410 is fixedly connected to the tray 100, the fixed shaft 410 can be a smooth columnar body, which can be integrally connected to the tray 100, or connected to the tray 100 by screws, latches, etc. The fixed shaft 410 can also be directly screwed or bolted to the tray 100.

[0055] The rotating pressure rod 420 is sleeved outside the fixed shaft 410 and can rotate around the fixed shaft 410, so that the rotating pressure rod 420 has a state opposite to the support surface 121 and a state misaligned with the support surface 121 when rotating. When the rotating pressure rod 420 is in a state opposite to the support surface 121, the side of the component to be supported facing away from the support surface 121 can be limited, thereby reducing the risk of the component to be supported falling off the positioning tooling. When the rotating pressure rod 420 is in a state misaligned with the support surface 121, an avoidance space can be provided for the component to be supported to be installed on the support surface 121.

[0056] Further, please refer to Figure 1 and Figure 2 , the rotating pressure rod 420 is slidably arranged on the fixed shaft 410 along the axial direction of the fixed shaft 410, and the pressing assembly 400 further includes an elastic member 430, and the elastic member 430 is clamped between the rotating pressure rod 420 and the tray 100.

[0057] By clamping the elastic member 430 between the rotating pressure rod 420 and the tray 100, the pressing assembly 400 has an initial position under the action of the elastic member 430. In the present invention, the initial position of the pressing assembly 400 can be set to a position where it can press the component to be supported, so that when the pressing assembly 400 avoids the component to be supported being placed on the support surface 121, the pressing assembly 400 can first be lifted in a direction away from the support surface 121, and rotate a certain angle in its lifted state, so that the rotating pressure rod 420 and the support surface 121 are misaligned with each other. At this time, the component to be supported is placed on the support surface 121. After the component to be supported is placed on the support surface 121, continue to keep the rotating pressure rod 420 in the lifted state and rotate it to a position where it can be opposite to the support surface 121, and then release the hand, so that the rotating pressure rod 420 returns to the initial position under the elastic action of the elastic member 430 to abut against the side of the component to be supported facing away from the support surface 121.

[0058] In one embodiment, please refer to Figure 1 and Figure 3 , the tray 100 includes an annular disk body 110 and a support table 120; the support table 120 protrudes from the inner wall of the annular disk body 110 and has a support surface 121, the fixed positioning member 200 is fixedly connected to the support table 120, and the movable positioning member 300 is movably connected to the support table 120.

[0059] The annular disk body 110, that is, the tray 100, has a structure with a hollow avoidance hole in the middle. The annular disk body 110 can be a circular disk body 110 or a rectangular ring-shaped disk body. When the support platform 120 protrudes from the inner wall of the annular disk body 110, the part to be supported can be placed on the support surface 121 of the support platform 120, so that the contact area between the part to be supported and the support platform 120 is small, avoiding the risk of wearing the part to be supported due to too large a contact area between the part to be supported and the tabletop of the support platform 120. The support platform 120 can be annular, or the support platform 120 is a convex block. When the support platform 120 is a convex block, there can be multiple support platforms 120, and multiple support platforms 120 protrude from the inner wall of the annular disk body 110 along the circumferential direction of the annular disk body 110. In addition, by protruding the support platform 120 from the inner wall of the annular disk body 110, when the user holds the positioning tooling, it can prevent the user's hand from touching the part to be supported placed on the support surface 121 of the support platform 120, thus avoiding the risk of contaminating or damaging the part to be supported.

[0060] By fixedly connecting the fixed positioning member 200 to the support platform 120 and movably connecting the movable positioning member 300 to the support platform 120, both the fixed positioning member 200 and the movable positioning member 300 are close to the part to be supported, so that the part to be supported can be effectively clamped.

[0061] Furthermore, as Figure 4 shown, the tray 100 has a bottom surface facing away from the support surface 121, and a handle groove 111 is provided on the bottom surface.

[0062] By providing the handle groove 111 on the bottom surface of the tray 100 facing away from the support surface 121, it is convenient for the user to hold the positioning tooling, and can further reduce the risk of the hand contaminating or damaging the part to be supported.

[0063] When the positioning tooling in the present invention positions the part to be supported, it includes the following steps:

[0064] First, align the part to be supported with the fixed positioning member 200 so that the fixed positioning member 200 abuts against one side of the part to be supported; and move the movable positioning member 300 relative to the tray 100 to avoid the part to be supported and place it on the support surface 121.

[0065] Then, release the movable positioning member 300 so that the movable positioning member 300 automatically moves to the clamping state to clamp the side of the part to be supported away from the fixed positioning member 200.

[0066] Finally, rotate the pressing assembly 400 to the pressing state to press the side of the part to be supported facing away from the support surface 121.

[0067] With such a setting, the movable positioning member 300 can provide an avoidance space during the installation of the member to be supported, so that the member to be supported can be smoothly placed on the support surface 121.

[0068] Further, before the step of aligning the member to be supported with the fixed positioning member 200 so that the fixed positioning member 200 abuts against one side of the member to be supported, the method further includes:

[0069] Rotate the pressing assembly 400 to make it in the second avoidance state. With such a setting, sufficient avoidance space can be provided when the member to be supported is installed on the support surface 121, reducing the risk of interference of the pressing assembly 400 with the member to be supported.

[0070] Based on the solution that the pressing assembly 400 includes a fixed shaft 410 and a rotating pressing rod 420, the fixed shaft 410 is fixedly connected to the tray 100; the rotating pressing rod 420 is sleeved outside the fixed shaft 410 and can rotate around the fixed shaft 410 to press the upper surface of the member to be supported, the step of rotating the pressing assembly 400 to make it in the second avoidance state is specifically:

[0071] Rotate the rotating pressing rod 420; so that the rotating pressing rod 420 is not arranged opposite to the support surface 121, that is, the rotating pressing rod 420 is arranged out of alignment with the support surface 121.

[0072] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent structural transformations made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
