It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] The following describes the gluing and positioning tooling for assembling parts according to an embodiment of the present application in conjunction with the accompanying drawings.

[0038] See also Figure 1 , Figure 1 A schematic structural diagram of a gluing and positioning tool for assembling parts of the present application is shown.

[0039] See also Figures 1-3 The gluing and positioning tooling comprises a chassis 1, a first support body 2, a second support body 3 and a pad 4. The chassis 1 is provided with a supporting plane 11. It can be understood that the supporting plane 11 is a flat surface used as a plane positioning reference during the processing.

[0040] The first support body 2 includes a first end face 21 and a second end face 22, wherein the first end face 21 is attached to the support plane 11, and the second end face 22 is perpendicular to the support plane 11. The second support body 3 includes a third end face 31, a fourth end face 32 and a fifth end face 33, wherein the third end face 31 is attached to the support plane 11, the fourth end face 32 abuts against the second end face 22, the fifth end face 33 is arranged on the side of the second support body 3 away from the fourth end face 32, and a sixth end face 34 perpendicular to the support plane 11 is also arranged between the fourth end face 32 and the fifth end face 33. The bottom surface of the pad 4 is fixed on the support plane 11, and the side wall of the pad 4 has a first positioning surface 41 and a second positioning surface 42 adjacent and perpendicular to each other, and the first positioning surface 41 abuts against the fifth end face 33.

[0041] When installing the gluing and positioning tooling, clean all the surfaces of the support plane 11, the first abutting body 2, the second abutting body 3, and the backing plate 4. Then attach the first end face 21 of the first abutting body 2 to the support plane 11, and then attach the third end face 31 of the second abutting body 3 to the support plane 11. At the same time, make the fourth end face 32 of the second abutting body 3 abut against the second end face 22 of the first abutting body 2 to keep the positions of the first abutting body 2 and the second abutting body 3 fixed. Finally, attach the bottom surface of the backing plate 4 to the support plane 11 and fix it. At the same time, make the first positioning surface 41 of the backing plate 4 abut against the fifth end face 33 of the second abutting body 3, and the second positioning surface 42 of the backing plate 4 does not protrude beyond the sixth end face 34 of the second abutting body 3.

[0042] After the gluing of the gluing and positioning tooling is completed, the gluing of the combined parts can be carried out. In some embodiments, refer to Figure 7 , the combined parts include a first part 5 and a second part 6 that are glued and connected. The gluing methods of the first part 5 and the second part 6 include optical glue fixation or applying a curing glue for bonding. The first part 5 is a small part, and the second part 6 is a large part.

[0043] Refer to Figures 1-6 , the top surface 43 of the backing plate 4 is parallel to the support plane 11 and forms a first positioning angle with the fifth end face 33 for abutting against the first part 5. The second end face 22, the sixth end face 34, and the support plane 11 are perpendicular to each other pairwise and form a second positioning angle for abutting against the second part 6.

[0044] During gluing, it is necessary to ensure that the small part is glued to the specified position on the gluing surface of the large part. The distance accuracy from the edge of the small part to the edge of the gluing surface is 0.02 mm. That is to say, the error of the gluing accuracy is not greater than 0.02 mm.

[0045] The steps of the gluing process of the combined parts are as follows: First, abut the second part 6 against the second positioning angle, abut the side wall of the second part 6 against the second end face 22 of the first part 5 and the sixth end face 34 of the second part 6, and abut the bottom surface of the second part 6 against the support plane 11, so that the gluing surface of the second part 6 is exposed between the included angle formed by the backing plate 4 and the second abutting body 3. The gluing surface of the second part 6 is used for gluing with the first part 5. In this way, through the second positioning angle formed by the first abutting body 2, the second abutting body 3, and the chassis 1, the second part 6 can be quickly and accurately positioned and fixed to the gluing position. Then abut the first part 5 against the first positioning angle. During the abutting process, make the side wall of the first part 5 abut within the first positioning angle formed by the fifth end face 33 and the second positioning surface 42, and abut the gluing surface of the first part 5 against the gluing surface of the second part 6, thereby realizing the positioning gluing of the first part 5 and the second part 6.

[0046] Through the gluing positioning tooling, the first part 5 and the second part 6 can be quickly and accurately fixed to the gluing position, improving the gluing accuracy of the first part 5 and the second part 6, reducing the gluing difficulty, making the processing steps simpler and more convenient while improving the gluing accuracy.

[0047] Among them, when machining the gluing positioning tooling, it can be found that the width of the sixth end face 34 determines a distance between the edge of the gluing surface of the first part 5 and the edge of the gluing surface of the second part 6. Here, this distance is called the first distance. At the same time, the thickness of the backing plate 4 determines another distance between the edge of the gluing surface of the first part 5 and the edge of the gluing surface of the second part 6. Here, this distance is called the second distance. The first distance and the second distance respectively represent the gluing positions of the first part 5 in the parallel direction and the vertical direction. That is, on the gluing surface of the second part 6, the horizontal distance between the edge of the gluing surface of the first part 5 and the edge of the gluing surface of the second part 6 is the first distance, and the vertical distance between the edge of the gluing surface of the first part 5 and the edge of the gluing surface of the second part 6 is the second distance. The control of the first distance and the second distance ensures the gluing accuracy of the first part 5.

[0048] Furthermore, the width of the sixth end face 34 of the second abutting body 3 is w, and the machining error of w is less than 0.02 mm. The height of the backing plate 4 is h, and the machining error of h is less than 0.02 mm.

[0049] When specifically machining the second abutting body 3 and the backing plate 4, multiple second abutting bodies 3 and backing plates 4 with different specifications can be set according to the actual situation. Exemplarily, the width of the second end face 22 on the second abutting body 3 can be machined to 10 mm, 11 mm, 12 mm, etc. Similarly, the height of the backing plate 4 can be machined to 3 mm, 4 mm, 5 mm, etc. No specific limitation is made here, but it is necessary to ensure that the machining error of the width of the sixth end face 34 of the second abutting body 3 and the height of the backing plate 4 is less than 0.02 mm.

[0050] Furthermore, referring to Figures 4-7 , the first part 5 includes a flat prism, and the second part 6 includes a Porro prism. The Porro prism has a terminal plane 61 and side faces. The bottom surface of the flat prism is adhesively connected to the terminal plane 61 of the Porro prism. The fifth end face 33 and the top surface 43 of the backing plate 4 are used to abut against the side faces of the flat prism, the second end face 22 is used to abut against the side faces of the Porro prism, and the sixth end face 34 is used to abut against the terminal plane 61 of the Porro prism.

[0051] Among them, the flat prism is a cylindrical prism with a bottom surface and two bottom surfaces. The Porro prism is also often called a Porro prism and is composed of two mutually perpendicular right-angled triangular prisms. These two triangular prisms are usually arranged at a certain angle (such as 45 degrees or 90 degrees) and change the optical path through internal total reflection. Referring to Figure 7, the bottom surface of the Porro prism (the second part 6) as a whole is the end plane 61 of the second part 6, and the side surface of the Porro prism is the side surface of the second part 6.

[0052] It can be found that the structure of the second part 6 is not a conventional rectangular prism. Its side surface is not completely perpendicular to the end plane 61. During conventional manual gluing, it is inconvenient to accurately position the second part 6, which will also affect the gluing accuracy of the first part 5 and the second part 6. Through the gluing positioning tooling, the second positioning angle formed by the chassis 1, the second end face 22 of the first part 5, and the sixth end face 34 of the second part 6 can ensure that the second part 6 is accurately positioned to the predetermined gluing position. At the same time, the first positioning angle formed by the top surface 43 of the backing plate 4 and the fifth end face 33 of the second part 6 can also ensure that the first part 5 is accurately positioned to the predetermined gluing position, thereby improving the gluing accuracy of the first part 5 and the second part 6.

[0053] Certainly, the gluing positioning tooling of the present application is not limited to gluing Porro prisms and flat prisms. The first part 5 can also be a rectangular prism or a conical prism, and the second part 6 can also be a rectangular prism or a conical prism, which are not specifically limited herein.

[0054] In some embodiments, refer to Figure 1 , Figure 2 and Figure 4 , the second positioning surface 42 and the sixth end face 34 are butted and in the same plane. When installing the backing plate 4, make the second positioning surface 42 of the backing plate 4 flush with the sixth end face 34 of the second abutment body 3, which can provide a larger abutting surface for the second part 6, make the accuracy of the second part 6 against the second positioning angle higher, and the structure is more stable after abutting.

[0055] In some embodiments, the height of the backing plate 4 relative to the support plane 11 is the first height, and the height of the second abutment body 3 relative to the support plane 11 is the second height. To ensure the formation of the first positioning angle, the first height is less than the second height.

[0056] In some embodiments, the backing plate 4 includes at least two gaskets (not shown in the figure). The vertical projection of each gasket on the support plane 11 is the same, and each gasket is detachably stacked along the direction perpendicular to the support plane 11 to form the backing plate 4.

[0057] It can be understood that the backing plate 4 is set as a detachable structure composed of a combination of multiple gaskets. By adjusting the number of stacked gaskets, the height of the backing plate 4 can be directly adjusted. Thus, the vertical distance between the edge of the gluing surface of the first part 5 and the edge of the gluing surface of the second part 6 can be directly adjusted, that is, the second distance can be directly adjusted, and there is no need to specially process multiple backing plates 4 with different thicknesses, so as to improve the applicable range of the backing plate 4 and the gluing positioning tooling.

[0058] Further, the second abutting body 3 includes at least two abutting plates, the perpendicular projections of each abutting plate on the second end face 22 are the same, and each abutting plate is detachably stacked along the direction perpendicular to the second end face 22 to form the second abutting body 3.

[0059] Similar to the cushion plate 4, the second abutting body 3 is provided with a detachable structure composed of a plurality of abutting plates. By adjusting the number of stacked abutting plates, the thickness of the sixth end face 34 on the second abutting body 3 can be directly adjusted. Thus, the horizontal distance between the glued surface edge of the first part 5 and the glued surface edge of the second part 6 can be directly adjusted, that is, the first distance can be directly adjusted, and there is no need to specially process a plurality of second abutting bodies 3 with different thicknesses, so as to improve the application range of the second abutting body 3 and the gluing positioning tooling.

[0060] Further, a plurality of gaskets are fixedly assembled to form the cushion plate 4 by optical gluing, and a plurality of abutting plates are assembled to form the first part 5 by optical gluing. During actual operation, only one cushion plate 4 can be used. At this time, this one cushion plate 4 is the gasket. Of course, only one abutting plate can also be used. At this time, this one abutting plate is the second abutting body 3.

[0061] In some embodiments, a first scale groove (not shown in the figure) is provided on the fifth end face 33 along the height direction of the cushion plate 4, and a second scale groove (not shown in the figure) is provided on the support plane 11 along the direction perpendicular to the second end face 22.

[0062] It can be understood that in addition to the height of the cushion plate 4 and the thickness of the sixth end face 34 on the second abutting body 3, the gluing positions of the first part 5 and the second part 6 can also be observed through the first scale groove and the second scale groove, further improving the gluing accuracy of the first part 5 and the second part 6.

[0063] In some embodiments, refer to Figures 1-6 , the first abutting body 2, the second abutting body 3 and the cushion plate 4 are all set as cuboid structures.

[0064] It can be understood that for the cuboid first abutting body 2, second abutting body 3 and cushion plate 4, the adjacent side faces are all right angles. When assembling the gluing positioning tooling, it is more convenient and accurate for the first abutting body 2, the second abutting body 3 and the cushion plate 4 to abut and position against each other, improving the assembly accuracy of the gluing positioning tooling itself.

[0065] Further, the first abutting body 2, the second abutting body 3 and the cushion plate 4 are all detachably connected to the support surface by optical gluing or gluing. Among them, the gluing method refers to applying a curing adhesive on the surface, and after the curing adhesive cures, it can position the first abutting body 2, the second abutting body 3 and the cushion plate 4.

[0066] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included within the protection scope of the present application.
