Description

Technical Field

[0001] The invention relates to the technical field of target material preparation, and in particular to a target material binding and positioning tool. Background Art

[0002] Target binding refers to welding the target material to the back target with solder. The existing technology generally uses indium as solder to bind the target material to the back plate. In the process of using indium to bind the target material, the target material and the back plate are first processed. Then the non-binding area of ​​the target material and the back plate is pasted with high-temperature tape. After that, the well-protected target material is placed on a heating furnace for heating, and the molten indium solder is poured onto the back plate and the target material, and the target material and the back plate are welded with ultrasound. After welding, the indium solder is filled on the back plate binding surface, and the target material is attached to the back plate. Finally, wait for the indium solder to solidify, the binding welding is completed, and the bound target material is obtained.

[0003] Due to the buoyancy of the molten indium solution, the target material and the back plate will move relative to each other after bonding, making it difficult to fix the target material in the center of the back plate. Therefore, a positioning tool is needed to locate the relative position of the target material and the back plate. So in some cases, the positioning tool often uses depth gauges, calipers and other measuring tools to locate the relative position of the target material and the back plate. However, since the binding of the target material is carried out at high temperature, it is necessary to wait for the measuring tool to cool down after each measurement and adjustment of the position. It is impossible to determine on the spot whether the positioning center of the target material and the back plate are consistent during the binding process, whether the concentricity is qualified, or to use a weight block to fix the binding position after each measurement and adjustment of the position to prevent the target material from shifting. Therefore, the efficiency is low and the positioning accuracy is low. Summary of the invention

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The purpose of the present invention is to provide a target material binding and positioning tool to solve the problems existing in the prior art, achieve high-precision center positioning when binding the target material, and improve the binding efficiency.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 to Figure 2 As shown, this embodiment provides a target binding and positioning tool, including a base 1, a target center positioning and measuring component 5 and a plurality of target positioning components 4, wherein the base 1 is preferably made of stainless steel; the base 1 includes a bottom positioning mechanism and a top positioning mechanism connected to each other; the bottom positioning mechanism is located on the outer peripheral side of the backing plate 6 and is fixed in position with the backing plate 6; the top positioning mechanism is an annular structure, preferably a circular annular structure, which is coaxially arranged above the backing plate 6 and surrounds the outer peripheral side of the target 7, wherein the inner diameter of the top positioning mechanism is larger than the outer diameter of the target 7, and its thickness is the same as or slightly higher than that of the target 7; each target positioning component 4 is evenly spaced along the circumference of the top positioning mechanism The target positioning assembly 4 is movably installed on the top positioning mechanism in the radial direction, and is used to abut against the outer peripheral wall of the target material 7. Specifically, the position of each target positioning assembly 4 on the top positioning mechanism is adjusted to be able to push the target material 7, thereby changing the position of the target material 7 on the back plate 6; the target center positioning measurement assembly 5 is installed at the top positioning mechanism, and is used to measure the position change of the target material 7. After the target positioning assembly 4 adjusts the position of the target material 7 on the back plate 6, the position of the target material 7 is measured by the target center positioning measurement assembly 5, so that the target material 7 can be quickly positioned and the target material 7 can be kept at the corresponding position on the back plate 6, thereby improving the binding accuracy and efficiency.

[0027] In one embodiment, to ensure that the bottom positioning mechanism and the back plate 6 are kept in a fixed position, the bottom positioning mechanism is connected to the back plate 6, or the bottom positioning mechanism is annular in structure, and its internal space structure matches the structure of the back plate 6, and then the back plate 6 is embedded inside the bottom positioning mechanism to achieve the first positioning of the back plate 6. This facilitates the subsequent adjustment of the target positioning assembly 4 to position the target 7 on the back plate 6 that has been positioned.

[0028] In one embodiment, the target material 7 and the back plate 6 are both circular structures. Since the top positioning mechanism is coaxial with the back plate 6, the center of the target material 7 is positioned by the target positioning assembly 4, so that the back plate 6 and the target material 7 are concentric circles. After the indium solution solidifies, the target positioning assembly 4 is released, the back plate 6 and the bottom positioning mechanism are separated, and the base 1 is removed to achieve accurate positioning of the target material 7 and the back plate 6, thereby achieving high-precision center positioning of the target material 7 when binding and improving the binding efficiency.

[0029] As a preferred embodiment of the present invention, the target center positioning measurement assembly 5 includes a plurality of first dial indicators distributed at equal intervals along the circumference of the top positioning mechanism, each first dial indicator is located between the two target positioning assemblies 4, and the measuring rod of the first dial indicator passes through the top positioning mechanism in the radial direction and abuts against the outer peripheral wall of the target 7, so as to measure the position of the target 7 through the first dial indicator. Since the top positioning mechanism is coaxial with the back plate 6, when the values ​​of the first dial indicators are consistent, it indicates that the center positioning of the target 7 is completed. Preferably, the first dial indicator is a digital dial indicator or a pointer dial indicator. In order to avoid the target 7 temperature being too high and affecting the accuracy of the reading, a pointer dial indicator is preferably used.

[0030] In one embodiment, the top positioning mechanism is equipped with three groups of target positioning components 4 and the first dial indicator, the top positioning mechanism is annular, and the target positioning components 4 and the first dial indicator in the same group are symmetrically distributed along the diameter direction of the top positioning mechanism to ensure the accuracy of positioning the target 7. The target positioning components 4 and the first dial indicators are distributed in a 120° fan shape.

[0031] Furthermore, the target positioning assembly 4 includes a first positioning rod 41 that is movably arranged along the radial direction of the top positioning mechanism, and the first positioning rod 41 extends radially along the top positioning mechanism, and the end of the first positioning rod 41 close to the target 7 is connected with a first protective block 42 for abutting against the outer peripheral wall of the target 7, and the first protective block 42 is preferably made of Teflon to ensure that the first protective block will not damage the target 7 when it contacts the side of the target 7. Among them, the first positioning rod 41 passes through the top positioning mechanism in the radial direction, and by pushing the first positioning rod 41 away from the end of the target 7, the first protective block 42 abuts against the target 7, thereby adjusting the position of the target 7.

[0032] Preferably, the first positioning rod 41 is in a screw-shaped structure, and a first screw hole threadedly connected to the first positioning rod 41 is provided on the top positioning mechanism, and the axis of the first screw hole extends along the radial direction of the top positioning mechanism to ensure that the first positioning rod 41 can be stably adjusted, thereby stably adjusting the position of the target material 7. The expansion and contraction amount of the first positioning rod 41 is adjusted to adjust the center position of the target material 7, and specifically, the first positioning rod 41 is rotated to achieve its expansion and contraction on the top positioning mechanism, thereby pushing the target material 7 to deflect.

[0033] Furthermore, in order to ensure that the position of the back plate 6 is fixed, the bottom positioning mechanism is in the form of an annular structure coaxial with the top positioning mechanism and surrounds the outer peripheral side of the back plate 6, wherein the inner diameter of the bottom positioning mechanism is larger than the outer diameter of the back plate 6, and its thickness is consistent with or slightly higher than the back plate 6. Preferably, the bottom positioning mechanism is coaxial with the top positioning mechanism and is integrally formed. The bottom positioning mechanism is equipped with a back plate center positioning measurement component 3 and a plurality of back plate positioning components 2; the back plate positioning components 2 are evenly spaced along the circumference of the bottom positioning mechanism, and the back plate positioning components 2 are movably mounted on the bottom positioning mechanism in the radial direction, and are used to abut against the outer peripheral wall of the back plate 6. The preferred bottom positioning mechanism is equipped with a support plate to place the back panel 6 and the entire base 1 on the support plate. Then, the position of each back panel positioning component 2 on the bottom positioning mechanism is adjusted to push the back panel 6 to slide along the support plate, thereby changing the position of the back panel 6; the back panel center positioning measurement component 3 is installed on the bottom positioning mechanism and is used to measure the position change of the back panel 6. After the back panel positioning component 2 adjusts the position of the back panel 6, the position of the back panel 6 is measured by the back panel center positioning measurement component 3, so that the back panel 6 can be quickly positioned and the back panel 6 can be kept at a position coaxial with the bottom positioning mechanism.

[0034] It can be seen that the present invention firstly realizes rapid fixing of the center position of the back plate 6 by the back plate positioning component 2 and the back plate center positioning and measuring component 3, and then rapidly fixes the center position of the target material 7 by the target material positioning component 4 and the target material center positioning and measuring component 5, thereby realizing concentric arrangement of the back plate 6 and the target material 7, and further realizing high-precision center positioning when binding the target material 7, thereby improving the binding efficiency.

[0035] As a preferred embodiment of the present invention, the back plate center positioning measurement assembly 3 includes a plurality of second dial indicators that are evenly spaced along the circumference of the bottom positioning mechanism, each second dial indicator is located between the two back plate positioning assemblies 2, and the measuring rod of the second dial indicator passes through the bottom positioning mechanism in the radial direction and abuts against the outer peripheral wall of the back plate 6. The position of the back plate 6 is measured by the second dial indicator. In one embodiment, the back plate 6 is a circular structure, and the bottom positioning mechanism is a circular ring structure. Then, when the values ​​of the second dial indicators are consistent, it indicates that the center positioning of the back plate 6 is completed. Preferably, the second dial indicator is a digital dial indicator or a pointer dial indicator. In order to avoid the high temperature of the back plate 6 affecting the accuracy of the reading, a pointer dial indicator is preferably used.

[0036] In one embodiment, the base 1 is equipped with three sets of back plate positioning components 2 and second dial indicators, the bottom positioning mechanism is annular, and the back plate positioning components 2 and second dial indicators in the same set are symmetrically distributed along the diameter direction of the bottom positioning mechanism to ensure the accuracy of positioning the back plate 6. The back plate positioning components 2 and the second dial indicators are distributed in a 120° fan shape.

[0037] Furthermore, the back plate positioning assembly 2 includes a second positioning rod 11 that is movably arranged along the radial direction of the bottom positioning mechanism, and the second positioning rod 11 extends radially along the bottom positioning mechanism. The end of the second positioning rod 11 close to the back plate 6 is connected to a second protection block 12 for abutting against the outer peripheral wall of the back plate 6. The second protection block 12 is preferably made of Teflon, which is resistant to high temperatures and will not scratch the metal surface, so as to ensure that the second protection block will not damage the back plate 6 when it contacts the side of the back plate 6. The second positioning rod 11 passes through the bottom positioning mechanism in the radial direction, and by pushing the second positioning rod 11 away from the end of the back plate 6, the second protection block 12 abuts against the back plate 6, thereby adjusting the position of the back plate 6.

[0038] Preferably, the second positioning rod 11 is in a screw-shaped structure, and a second screw hole threadedly connected to the second positioning rod 11 is provided on the bottom positioning mechanism, and the axis of the second screw hole extends along the radial direction of the bottom positioning mechanism. This ensures that the second positioning rod 11 can be stably adjusted, and thus the position of the back plate 6 can be stably adjusted. The extension amount of the second positioning rod 11 is adjusted to adjust the center position of the back plate 6. Specifically, the second positioning rod 11 is rotated to achieve its extension on the bottom positioning mechanism, thereby pushing the back plate 6 to deflect.
