[0039] In some embodiments, the support assembly 103 is integrally formed with the base plate 101, or the support assembly 103 is fixed to the base plate 101 by welding, or the support assembly 103 is detachably connected to the base plate 101. When the support assembly 103 is detachably connected to the base plate 101, different support assemblies 103 can be replaced for different products X to be tested, and the position of the support assembly 103 on the base plate 101 can be adjusted so that the support assembly 103 is adapted to the product X to be tested. On the one hand, the utilization rate of the support assembly 103 can be improved and the use scenarios of the support assembly 103 can be increased.

[0045] The straightness detection device 10 of this embodiment drives the product X to be tested to rotate through the transmission component 105 to perform straightness detection on all four sides of the product X to be tested. In addition, during the rotation of the product X to be tested, the positioning component 104 can be used to fix the position of the product X to be tested to avoid affecting the straightness detection result of the product X to be tested, so as to improve the accuracy of the detection result.

[0046] See also Figure 3 and Figure 4 , Figure 3 is a schematic diagram of a straightness detection device 10 in some embodiments of the present application, Figure 4 1 is a schematic diagram of the first support member in some embodiments of the present application. The support assembly 103 includes a plurality of first support members 1031, the plurality of first support members 1031 are arranged at intervals along the first direction x1, the plurality of first support members 1031 are used to place the product X to be tested, and the transmission assembly 105 is arranged on the first support member 1031 on the support assembly 103.

[0048] When the first support member 1031 is detachably connected to the bottom plate 101, the first support member 1031 can be fixed to the bottom plate 101 by a fastener. Specifically, the bottom plate 101 and the first support member 1031 respectively have a plurality of first connection holes and second connection holes arranged at intervals, and the fastener can be inserted into the first connection holes and the second connection holes to fix the first support member 1031 to the bottom plate 101.

[0053] See also Figure 5 , Figure 6 and Figure 7 , Figure 5 is a schematic diagram of the first support member 1031 in some embodiments of the present application, Figure 6 is a schematic diagram of the transmission assembly 105 in some embodiments of the present application, Figure 7 is a schematic diagram of the transmission assembly 105 in some embodiments of the present application. Among them, Figure 5 -① is a schematic diagram of the first support member 1031 from another angle, Figure 5 -② is a schematic cross-sectional view of the first support member 1031.

[0054] The transmission assembly 105 includes an adjusting member 1051, a bearing 1052, a first rotating shaft 1053, a second rotating shaft 1054 and a transmission member 1055. The first support member 1031 is provided with a first through hole O1, the bearing 1052 is provided in the first through hole O1, parts of the first rotating shaft 1053 and the second rotating shaft 1054 pass through the first through hole O1 and the bearing 1052, the adjusting member 1051 is provided at one end of the first rotating shaft 1053, the other end of the first rotating shaft 1053 is in contact with one end of the second rotating shaft 1054, the transmission member 1055 is in contact with the other end of the second rotating shaft 1054 and the product X to be tested, respectively, and the adjusting member 1051 drives the product X to be tested to rotate through the first rotating shaft 1053, the second rotating shaft 1054, the bearing 1052 and the transmission member 1055.

[0055] In some embodiments, the size of the first through hole O1 of the first support member 1031 is set according to actual conditions. For example, the first support member 1031 is a cuboid with a length of 4 cm, a width of 2 cm and a height of 7 cm, and the diameter of the first through hole O1 is 1.4 cm, 1.6 cm or 1.8 cm, and a cylinder with a height of 2 cm.

[0056] In some embodiments, see Figure 5 In the middle figure ②, the first through hole O1 includes a first section through hole, a second section through hole and a third section through hole, and the second section through hole is located between the first section through hole and the third section through hole. The first section through hole and the third section through hole are used to place the bearing 1052, and the aperture of the second section through hole needs to be slightly larger than the diameter of the first rotating shaft 1053, so that the first rotating shaft 1053 can pass through the first through hole O1. It can be understood that the aperture of the second section through hole is smaller than the aperture of the first section through hole or the third section through hole.

[0057] In some embodiments, the adjusting member 1051 may be a handle, a knob or a grip, and the adjusting member 1051 may be prepared by a knurling process to prevent slipping and the like when the user turns the adjusting member 1051 .

[0058] In some embodiments, the adjusting member 1051 and the first rotating shaft 1053 may be sleeved on one end of the first rotating shaft 1053, or the adjusting member 1051 and the first rotating shaft 1053 may be connected by a fastener, wherein the fastener may include a stud, a bolt, a screw and / or a nut.

[0059] In some embodiments, the first rotating shaft 1053 and the second rotating shaft 1054 may be fixedly connected by welding, or the first rotating shaft 1053 and the second rotating shaft 1054 may be fixedly connected by fasteners, wherein the fasteners may include studs, bolts, screws and / or nuts.

[0060] In some embodiments, the shapes of the first rotating shaft 1053 and the second rotating shaft 1054 are different. Figure 7 As shown, the first rotating shaft 1053 is in the shape of a cylinder, and the second rotating shaft 1054 is in the shape of a hexagonal column. When the adjusting member 1051 drives the first rotating shaft 1053 to rotate, the second rotating shaft 1054 rotates at the same time. Since the shapes of the first rotating shaft 1053 and the second rotating shaft 1054 are inconsistent, at this time, the transmission member 1055 abutting against the second rotating shaft 1054 will not slip, and the transmission member 1055 can transmit smoothly, and then under the action of the friction force between the transmission member 1055 and the product X to be tested, the product X to be tested is driven to rotate.

[0061] In other embodiments, the first rotating shaft 1053 and the second rotating shaft 1054 have the same shape, for example, the first rotating shaft 1053 and the second rotating shaft 1054 are both cylindrical, in which case it is necessary to fix the second rotating shaft 1054 and at least a portion of the transmission member 1055 and / or the second rotating shaft 1054 and the product to be tested X to ensure that the transmission member 1055 and the product to be tested X can rotate with the second rotating shaft 1054. It is worth noting that when the second rotating shaft 1054 and at least a portion of the transmission member 1055 are fixed, the transmission member 1055 cannot be driven to rotate 360 ​​degrees, and the fixing position of the second rotating shaft 1054 / the product to be tested X and the transmission member 1055 needs to be constantly changed, which is quite limited.

[0062] In some embodiments, the size of the bearing 1052 is set according to actual conditions. However, it needs to be satisfied that the bearing 1052 can be placed in the first through hole O1 and the first rotating shaft 1053 can pass through the bearing 1052 .

[0063] In some embodiments, the transmission member 1055 may be a transmission belt, such as a silicone belt or a rubber belt. The transmission belt is sleeved around the product X to be tested and the second rotating shaft 1054, and the product X to be tested and the second rotating shaft 1054 are located on opposite sides of the transmission belt.

[0064] In some embodiments, the size of the transmission assembly 105 can be determined according to actual conditions. In one application scenario, the length range of the transmission assembly 105 is 9.55 cm and the width range is 1 to 1.2 cm; wherein the adjustment member 1051 is a hexagonal prism with a diameter of 1 cm and a length of 2.5 cm; the bearing 1052 is a hollow cylinder with a diameter of 1.2 cm and a length of 0.85 cm; the first rotating shaft 1053 is a cylinder with a diameter of 1 cm and a length of 4.55 cm; and the second rotating shaft 1054 is a hexagonal prism with a diameter of 0.8 cm and a length of 2.5 cm.

[0065] In some embodiments, the positional relationship between the first rotating shaft 1053 and the bearing 1052 can be determined according to the length of the first rotating shaft 1053 and / or the length of the bearing 1052. For example, the bearing 1052 is a hollow cylinder with a diameter of 1.2 cm and a length of 0.85 cm, the first rotating shaft 1053 is a cylinder with a diameter of 1 cm and a length of 4.55 cm, the length of the first rotating shaft 1053 on the left side of the bearing 1052 is 1.2 cm, and the length of the first rotating shaft 1053 on the right side of the bearing 1052 is 2.5 cm.

[0066] See also Figure 3 and Figure 8 ,in, Figure 8 1 is a schematic diagram of a second support member in some embodiments of the present application. The support assembly 103 further includes a plurality of second support members 1032, the second support members 1032 are arranged corresponding to the first support members 1031, one end of the second support member 1032 is fixed to the corresponding first support member 1031, the other end of the second support member 1032 is spaced apart from the corresponding first support member 1031, and the positioning assembly 104 is arranged at the other end of the second support member 1032.

[0067] In some embodiments, the second support member 1032 and the first support member 1031 are integrally formed, or the second support member 1032 is fixed to the first support member 1031 by welding, or the second support member 1032 and the first support member 1031 are detachably connected.

[0068] When the second support member 1032 is detachably connected to the first support member 1031, the second support member 1032 can be fixed to the first support member 1031 by a fastener. Specifically, a plurality of third connection holes and fourth connection holes arranged at intervals are respectively provided on the first support member 1031 and the second support member 1032, and the fastener can be inserted into the third connection holes and the fourth connection holes to fix the second support member 1032 to the first support member 1031. The fastener can include a stud, a bolt, a screw and / or a nut, and the number, position and other information of the third connection holes and the fourth connection holes can be determined according to actual conditions.

[0069] It can be understood that when the first support member 1031 and the second support member 1032 are detachably connected, not only can different first support members 1031 and / or second support members 1032 be replaced for different products X to be tested, but the position of the second support member 1032 on the first support member 1031 can also be adjusted to make the second support member 1032 compatible with the product X to be tested. On the one hand, the utilization rate of the first support member 1031 and the second support member 1032 can be improved, and the use scenarios of the first support member 1031 and the second support member 1032 can be increased. On the other hand, the dynamic adjustment method can save costs.

[0070] In some embodiments, parameters such as shape, length, width and height of the second support member 1032 can be set according to actual conditions.

[0071] In an application scenario, such as Figure 8 As shown, the cross section of the second support member 1032 is L-shaped, and the length of one end of the L-shape is 3 cm and the width is 1.2 cm, and the length of the other end of the L-shape is 2.5 cm and the width is 1.5 cm. The second support member 1032 has three through holes, two of which are fourth connection holes.
