[0028] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0029] Please see Figures 1 to 3This application provides an auxiliary measuring fixture 100, which can be used to assist in positioning and fixing a product to be measured (not shown in the figure) to facilitate photographing the product and measuring its dimensions (length, width, thickness), component position, cutting point size, angle, glue filling condition, soldering condition, etc. The product can be, but is not limited to, SMT electronic products, such as rigid boards, flexible boards, and rigid-flex boards. Of course, the auxiliary measuring fixture 100 can also be used to position and fix other products in other scenarios, and this application does not impose any limitations.

[0030] like Figures 1 to 3 As shown, an auxiliary measuring fixture 100 according to an embodiment of this application includes a base plate 10, a damper 20, and a carrier plate 30. The damper 20 is fixed to the base plate 10 and includes a body 22 and a rotating shaft 21 connected to the body 22 (see figure). Figure 4 The rotating shaft 21 extends from the main body 22, which is fixed to the base plate 10. The carrier plate 30 is used to support the product. The carrier plate 30 is rotatably connected to the base plate 10 via the rotating shaft 21 of the damper 20. That is, the carrier plate 30 can rotate relative to the base plate 10 with the rotating shaft 21 as the center. Due to the action of the damper 20, the carrier plate 30 can rotate freely at different angles and hover at the angle desired by the operator, thereby suspending and fixing the product at the desired angle. This allows for convenient subsequent measurement and other operations without changing the fixture, meeting the measurement needs of different angles and improving measurement efficiency.

[0031] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the auxiliary measuring fixture 100 may also include a cover plate 40. A magnet (not shown) is provided within the carrier plate 30, which can be used to attract the cover plate 40, thereby fixing the product to be measured between the carrier plate 30 and the cover plate 40. When the auxiliary measuring fixture 100 is not in use, the cover plate 40 can be fixed to the surface of the carrier plate 30 by the attraction of the magnet within the carrier plate 30; in use, the cover plate 40 can be removed first, then the product can be placed on the surface of the carrier plate 30, and then the cover plate 40 can be placed over the surface of the product facing away from the carrier plate 30. Because the base plate 10 contains a magnet, the attraction of the magnet can attract the cover plate 40, thereby clamping and fixing the product between the carrier plate 30 and the cover plate 40, ensuring that the product does not fall.

[0032] In some embodiments, such as Figure 1 and Figure 2 As shown, the surface of the carrier plate 30 facing the cover plate 40 is provided with positioning posts 31, and the number of positioning posts 31 can be multiple. Figure 4As shown, the cover plate 40 has openings 41 extending through it along its thickness direction. Multiple openings 41 can be provided, their number equal to the number of positioning posts 31. Positioning posts 31 can extend from the openings 41, thereby fixing and limiting the product. In this embodiment, both the number of positioning posts 31 and the number of openings 41 are four. Two of the openings 41 are semi-circular holes located on the edge of one side of the cover plate 40; the other two openings 41 can be circular holes.

[0033] In some embodiments, such as Figure 3 and Figure 4 As shown, the base plate 10 includes a first portion 11 and a second portion 12 connected together. The thickness of the first portion 11 is greater than the thickness of the second portion 12. A damper 20 is mounted on the side surface of the first portion 11 and is located in the region of the first portion 11 near the second portion 12. A carrier plate 30 is rotatably connected to the second portion 12, and the connection point is located in the region of the second portion 12 near the first portion 11. The thickness difference between the first portion 11 and the second portion 12 facilitates the rotation of the carrier plate 30.

[0034] In some embodiments, such as Figure 3 and Figure 4 As shown, two dampers 20 are respectively mounted on opposite side surfaces of the first part 11. The first part 11 and the second part 12 are arranged in a first direction X, and a second direction Y perpendicular to the first direction X and the thickness direction Z of the base plate 10. The side surfaces on which the dampers 20 are mounted are the two side surfaces of the first part 11 that are opposite each other along the second direction Y.

[0035] Furthermore, such as Figure 4 As shown, the first part 11 has a first mounting hole 110, and the body 22 has a second mounting hole 220 (which can be a through hole) penetrating the body 22. The positions of the first mounting hole 110 and the second mounting hole 220 are corresponding, and the number is equal. There can be one or more first mounting holes 110 and second mounting holes 220. Both the first mounting hole 110 and the second mounting hole 220 can be threaded holes. Bolts (not shown in the figure) can be screwed into the first mounting holes 110 and the second mounting holes 220 to fix the body 22 of the damper 20 to the first part 11 of the base plate 10. The method of fixing the damper 20 to the base plate 10 by bolts and mounting holes is simple and reliable in connection structure, and convenient for disassembly and replacement.

[0036] In some embodiments, such as Figures 2 to 4As shown, the auxiliary measuring fixture 100 also includes a connector 50 for connecting the carrier plate 30 and the damper 20. There may be two connectors 50, each fixed to the surface of the carrier plate 30 facing the damper 20. Each connector 50 has a third mounting hole 51 (which may be a through hole) extending through the connector 50. The rotating shaft 21 of the damper 20 is inserted into the third mounting hole 51, thereby connecting the carrier plate 30 and the damper 20, allowing the carrier plate 30 to rotate under the action of the damper 20.

[0037] Furthermore, each connector 50 may also be provided with a fourth mounting hole 52 penetrating through the connector 50 (the fourth mounting hole 52 may be a through hole). The fourth mounting hole 52 may be located above the third mounting hole 51, which is closer to the damper 20 than the fourth mounting hole 52. Each connector 50 may have two fourth mounting holes 52 and one third mounting hole 51. The carrier plate 30 is provided with a fifth mounting hole (not shown) corresponding to the fourth mounting hole 52. The fourth and fifth mounting holes may be threaded holes. By screwing bolts into the fourth and fifth mounting holes, the connector 50 can be fixed to the carrier plate 30. This method of fixing the connector 50 to the carrier plate 30 using bolts and mounting holes provides a simple and reliable connection structure, and facilitates disassembly and replacement.

[0038] In some embodiments, such as Figure 1 and Figure 4 As shown, in the base plate 10, the surface portion of the first part 11 facing the second part 12 is recessed in a direction away from the second part 12, thereby forming a groove 120. The bottom wall of the groove 120 may be an arc surface. The number of grooves 120 is equal to the number of connectors 50, which is also two. Each groove 120 is used to accommodate a portion of the connector 50 corresponding to that groove 120. When the connector 50 rotates under the action of the damper 20, the groove 120 provides space for the rotation of the connector 50. The end of the connector 50 near the groove 120 has an arc-shaped surface, thereby facilitating the rotation of the connector 50.

[0039] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the carrier plate 30 is provided with a handle 32. The handle 32 may be located in the edge area of ​​the carrier plate 30 and protrude from the main surface of the carrier plate 30, and the handle 32 protrudes from the cover plate 40. The number of handles 32 may be one or more; in this embodiment, the number of handles 32 is two. The handle 32 may be spherical, but of course, the handle 32 may also be other regular or irregular shapes. The handle 32 is used for the operator to grip, so as to facilitate the operator to apply force on the carrier plate 30 to rotate the carrier plate 30.

[0040] In some embodiments, the cover plate 40 is made of stainless steel, and the thickness of the stainless steel can be 0.1 mm. When the cover plate 40 is made of stainless steel, it is not necessary to embed a magnet inside the cover plate 40, as the magnet in the carrier plate 30 has a magnetic attraction to the stainless steel. In other embodiments, the cover plate 40 is made of acrylic, and a magnet is embedded in the acrylic. The acrylic is transparent, and the transparent cover plate 40 will not obstruct the product, making it convenient to photograph the product.

[0041] In some embodiments, the carrier plate 30 is made of aluminum alloy; in other embodiments, the carrier plate 30 is made of acrylic. Regardless of whether the carrier plate 30 is made of aluminum alloy or acrylic, it contains magnets.

[0042] In use, remove the cover plate 40, place the product to be measured on the carrier plate 30, and use the positioning pins 31 to initially position and fix the product. Then, align the opening 41 on the cover plate 40 with the positioning pins 31, and place the cover plate 40 over the product surface. The magnet inside the carrier plate 30 attracts the cover plate 40, thereby clamping and fixing the product between the carrier plate 30 and the cover plate 40 to prevent the product from falling. At this point, it is approximately as follows: Figure 1 As shown, the product can be laid flat, with the cover plate 40, the product, and the carrier plate 30 approximately parallel to the base plate 10, and the angle between the carrier plate 30 and the base plate 10 being 0°. After measuring the product in its flat position, the operator can hold the handle 32 and apply force to the carrier plate 30, causing the carrier plate 30, the product on it, and the cover plate 40 to rotate. The damper 20 can be used to stop the carrier plate 30 and the product at any position, for example, at any position where the angle between the carrier plate 30 and the base plate 10 is between 0° and 180°. For example, as... Figure 2 and Figure 3 As shown, the carrier plate 30 can be suspended at a position approximately perpendicular to the base plate 10 (with an included angle of 90°) to measure the product.

[0043] The auxiliary measuring fixture 100 of this application embodiment provides a damper 20 and a carrier plate 30 on the base plate 10, which allows the carrier plate 30 to rotate relative to the base plate 10 and fix the product at different angles. This allows the product to be easily subjected to subsequent measurement operations without changing the fixture, thus meeting the measurement needs at different angles and improving measurement efficiency.

[0044] The above description describes some specific embodiments of this application, but in actual applications, the application should not be limited to these embodiments. For those skilled in the art, other modifications and alterations made based on the technical concept of this application should fall within the protection scope of this application.
