[0021] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] like Figures 1 to 3 As shown in the figure, the fixture fixing mechanism 10 provided in this embodiment of the present invention is installed on a fixture inspection machine. The fixture fixing mechanism 10 includes a support frame 1, a limiting component, and a plurality of first locking structures 2. The support frame 1 includes a support module 1a, which includes a plurality of support parts 101 and a plurality of first locking parts 102. The plurality of support parts 101 are arranged sequentially at intervals along a first direction x, and a first locking part 102 is provided between every two adjacent support parts 101. The support parts 101 are used to place the fixture 20, and each first locking part 102 is respectively equipped with at least one first locking structure 2.

[0023] The first locking structure 2 has a locking state that can lock the jigs 20 on two adjacent support portions 101 to the support frame 1, and an unlocking state that can allow the jigs 20 to be placed on or removed from the support portion 101 by avoiding the support portion 101.

[0024] The limiting component is installed on the support frame 1 and is used to limit the fixtures 20 on each support part 101.

[0025] When each of the first locking structures 2 is in the locked state, the jig 20 can be clamped between the adjacent first locking structure 2 and the support portion 101. When each of the first locking structures 2 is in the unlocked state, the first locking structure 2 avoids the support portion 101, so that the jig 20 can be placed on the support portion 101, or the jig 20 can be removed from the support portion 101.

[0026] The fixture fixing mechanism 10 provided in this embodiment of the utility model is provided with multiple support parts 101 and multiple first locking parts 102 in the support module 1a of the support frame 1, so that multiple fixtures 20 can be supported simultaneously by the multiple support parts 101. When the fixture 20 is placed on each support part 101, it can be limited by the limiting component to prevent the fixture 20 from tilting and affecting the accuracy of subsequent testing. When fixing the fixture 20, each first locking structure 2 can be moved to the unlocked state firstly, so that multiple fixtures 20 can be placed on the multiple support parts 101 respectively. After the multiple fixtures 20 are placed on the multiple support parts 101 respectively, each first locking structure 2 moves to the locked state to fix the fixture 20 on each support part 101. Since the first locking structure 2 can simultaneously lock the fixtures 20 on two adjacent support portions 101, the fixing efficiency of the fixtures 20 can be improved. Furthermore, since the fixture fixing mechanism 10 can simultaneously fix multiple fixtures 20, multiple fixtures 20 can be inspected simultaneously, improving inspection efficiency. At the same time, since the first locking structure 2 can rotate and limit the fixtures 20 on two adjacent support portions 101, the placement of the fixtures 20 on the corresponding support portions 101 can be more precise, improving inspection accuracy.

[0027] In one embodiment, such as Figure 2 and Figure 3 As shown, the first locking structure 2 includes a first mounting shaft 21 and a first locking block 22. The first end of the first mounting shaft 21 is mounted to the first locking part 102, and the second end of the first mounting shaft 21 is rotatably connected to the first locking block 22. The rotation axis of the first locking block 22 extends along the height direction of the fixture 20. For example, in... Figures 1 to 3 In the embodiment shown, the third direction z is parallel to the height direction of the fixture 20. Similarly, the rotation axis of the first locking block 22 is parallel to the third direction z.

[0028] When the first locking block 22 rotates relative to the first mounting shaft 21, the first locking structure 2 can switch between the locked state and the unlocked state.

[0029] For example, the first locking block 22 can be rotated manually to switch the state of the first locking structure 2.

[0030] When the first locking structure 2 is required, the first locking block 22 can be rotated relative to the first mounting shaft 21. This fixing method is simple and can improve the fixing efficiency of the fixture 20.

[0031] In an embodiment not shown in the figure, the first locking block can also be rotated electrically. In this case, the first mounting shaft may not be provided. That is, the first locking structure includes an electric drive structure and a first locking block. The electric drive structure is mounted on the first locking part, and the output end of the electric drive structure is connected to the first locking block. The electric drive structure drives the first locking block to rotate, thereby achieving the state switching of the first locking structure. Schematic, the electric drive structure can be a rotary motor or a rotary cylinder, or other structure capable of rotary drive.

[0032] In one embodiment, such as Figure 2 and Figure 3 As shown, in two adjacent support portions 101, one support portion 101 is the first support portion 101a, and the other support portion 101 is the second support portion 101b. The jig 20 on the first support portion 101a is the first jig 20a, and the jig 20 on the second support portion 101b is the second jig 20b.

[0033] The first locking block 22 includes a first locking section 221, a second locking section 222 and a first connecting section 223. The first connecting section 223 is connected between the first locking section 221 and the second locking section 222. The second end of the first mounting shaft 21 is rotatably connected to the first connecting section 223.

[0034] When the first locking structure 2 is in the locked state, the first locking segment 221 can cooperate with the first support portion 101a to clamp the edge of the first fixture 20a, and the second locking segment 222 can cooperate with the second support portion 101b to clamp the edge of the second fixture 20b.

[0035] Therefore, when the first locking structure 2 is in the locked state, the first fixture 20a can be fixed by the clamping of the edge of the first fixture 20a by the first locking section 221 and the first support part 101a, and the second fixture 20b can be fixed by the clamping of the edge of the second fixture 20b by the second locking section 222 and the second support part 101b. The first locking structure 2 will fix two adjacent fixtures 20 at the same time.

[0036] In one embodiment, such as Figure 2 and Figure 3As shown, the limiting component includes a first limiting structure 3. Each first locking part 102 is equipped with a first limiting structure 3. The first limiting structure 3 is used to rotate and limit the fixtures 20 on two adjacent support parts 101, thereby preventing the fixtures 20 placed on the support parts 101 from rotating and affecting the subsequent fixing and testing of the fixtures 20.

[0037] In one embodiment, such as Figure 2 and Figure 3 As shown, the first limiting structure 3 includes a limiting member 31. Each first locking part 102 is equipped with multiple limiting members 31 so that the fixtures 20 on two adjacent support parts 101 can be rotated and limited simultaneously by the multiple limiting members 31.

[0038] For example, a plurality of limiting members 31 installed on the same first locking part 102 are spaced apart along the second direction y, and the first locking structure 2 is disposed between any two limiting members 31.

[0039] For example, the limiting member 31 is a cylindrical structure. In other embodiments not shown in the figure, the limiting member may also be an elongated structure extending along the second direction. When the limiting member is an elongated structure, only one limiting member may be installed on the first locking part.

[0040] In one embodiment, such as Figure 2 and Figure 3 As shown, the support module 1a also includes a second locking part 103 and a third locking part 104. Multiple support parts 101 and multiple first locking parts 102 within the same support module 1a are located between the second locking part 103 and the third locking part 104 along a first direction x.

[0041] Among the multiple support portions 101 within the same support module 1a, the two support portions 101 located at the outermost edges along the first direction x are the first edge support portion 101c and the second edge support portion 101d, respectively. The second locking portion 103 is disposed along the first direction x on the side of the first edge support portion 101c away from the second edge support portion 101d, and the third locking portion 104 is disposed along the first direction x on the side of the second edge support portion 101d away from the first edge support portion 101c.

[0042] The fixture fixing mechanism 10 also includes a second locking structure 4 and a third locking structure 5. The second locking structure 4 is installed on the second locking part 103 and can lock the fixture 20 on the first edge support part 101c. The third locking structure 5 is installed on the third locking part 104 and can lock the fixture 20 on the second edge support part 101d.

[0043] To prevent the edge of the jig 20 located at the outermost edge of the first direction x from lifting or slipping off the edge of the support module 1a along the first direction x, a second locking part 103 and a third locking part 104 can be respectively provided on both sides of the support module 1a along the first direction x. A second locking structure 4 is installed on the second locking part 103 and a third locking structure 5 is installed on the third locking part 104. The edges of the jig 20 at the outermost edges on both sides of the first direction x are locked by the second locking structure 4 and the third locking structure 5, so that the jig fixing mechanism 10 can fix the jig 20 at the outermost edges on both sides of the first direction x more stably.

[0044] In one embodiment, such as Figure 2 and Figure 3 As shown, the structures of the second locking structure 4 and the third locking structure 5 can be consistent with the structure of the first locking structure 2. Specifically, the second locking structure 4 may include a second mounting shaft and a second locking block. The first end of the second mounting shaft is mounted on the second locking part 103, and the second end of the second mounting shaft is rotatably connected to the second locking block. The rotation axis of the second locking block extends along the height direction of the fixture 20.

[0045] By rotating the second locking block relative to the second mounting shaft, the second locking structure 4 can lock the jig 20 on the first edge support 101c; or the second locking structure 4 can avoid the first edge support 101c, and the jig 20 can be placed on or removed from the first edge support 101c.

[0046] The third locking structure 5 includes a third mounting shaft and a third locking block. The first end of the third mounting shaft is mounted on the third locking part 104, and the second end of the third mounting shaft is rotatably connected to the third locking block. The rotation axis of the third locking block extends along the height direction of the fixture 20.

[0047] By rotating the third locking block relative to the third mounting axis, the third locking structure 5 can lock the jig 20 on the second edge support 101d; or the third locking structure 5 can avoid the second edge support 101d, and the jig 20 can be placed on or removed from the second edge support 101d.

[0048] In one embodiment, such as Figure 2 and Figure 3 As shown, the limiting component includes a second limiting structure 6, which is installed on the second locking part 103. The second limiting structure 6 is used to rotate and limit the fixture 20 on the first edge support part 101c, thereby preventing the fixture 20 placed on the first edge support part 101c from rotating and affecting the subsequent fixing and detection of the fixture 20.

[0049] In one embodiment, such as Figure 2 and Figure 3 As shown, the limiting component includes a third limiting structure 7, which is installed on the third locking part 104. The third limiting structure 7 is used to rotate and limit the fixture 20 on the second edge support part 101d, thereby preventing the fixture 20 placed on the second edge support part 101d from rotating and affecting the subsequent fixing and testing of the fixture 20.

[0050] In one embodiment, such as Figure 2 and Figure 3 As shown, multiple support modules 1a are provided, and the multiple support modules 1a are spaced apart along the second direction y. The first direction x is perpendicular to the second direction y.

[0051] By setting multiple support modules 1a, the fixture fixing mechanism 10 can fix more fixtures 20 at once, thereby improving testing efficiency.

[0052] In one embodiment, such as Figure 2 and Figure 3 As shown, the multiple support parts 101 of the multiple support modules 1a are arranged in a matrix.

[0053] The support frame 1 also includes a limiting module 1b, with a limiting module 1b provided for every two adjacent support modules 1a along the second direction y. The limiting module 1b includes a limiting part 105 provided between two adjacent support parts 101 along the second direction y.

[0054] The limiting component includes a fourth limiting structure 8. Each limiting part 105 is equipped with a fourth limiting structure 8. The fourth limiting structure 8 is used to rotate and limit the fixtures 20 on two adjacent support parts 101 along the second direction y, thereby preventing the two adjacent fixtures 20 from rotating and affecting the subsequent fixing and testing of the fixtures 20.

[0055] In one embodiment, such as Figure 2 and Figure 3 As shown, the structures of the second limiting structure 6, the third limiting structure 7, and the fourth limiting structure 8 can all be the same as the structure of the first limiting structure 3, that is, the second limiting structure 6, the third limiting structure 7, and the fourth limiting structure 8 can all include limiting elements.

[0056] In one embodiment, such as Figure 2 and Figure 3 As shown, the support part 101 is provided with a threaded hole. The fixture fixing mechanism 10 also includes a fixing bolt 9, which can pass through the through hole on the fixture 20 and be threadedly connected to the threaded hole to fix the fixture 20 on the support frame 1.

[0057] For example, when the support frame 1 is provided with both locking structures (first locking structure 2, second locking structure 4, and third locking structure 5) and threaded holes, the fixture 20 can be fixed by either the locking structures or by the fixing bolts 9.

[0058] In one embodiment, such as Figure 1 As shown, the support frame 1 includes a base plate 11, a support column 12 and a support plate 13. The support column 12 is connected between the base plate 11 and the support plate 13, and the support module 1a is disposed on the support plate 13.

[0059] Therefore, the support frame 1 is composed of a base plate 11, a support column 12 and a support plate 13. In addition to the support module 1a being set on the support plate 13, the limiting module 1b is also set on the support plate 13.

[0060] This utility model embodiment also provides a fixture inspection machine, including an inspection platform, a detection device, and the aforementioned fixture fixing mechanism 10. The fixture fixing mechanism 10 is installed on the inspection platform, and the detection device is used to inspect the fixture 20.

[0061] The fixture inspection machine provided in this embodiment of the utility model has a fixture fixing mechanism 10 with multiple support parts 101 and multiple first locking parts 102 provided on the support module 1a of the support frame 1, so that multiple fixtures 20 can be supported simultaneously by the multiple support parts 101. When fixing the fixtures 20, each of the first locking structures 2 can be moved to the unlocked state first, so that multiple fixtures 20 can be placed on the multiple support parts 101 respectively. After the multiple fixtures 20 are placed on the multiple support parts 101 respectively, each of the first locking structures 2 moves to the locked state to fix the fixtures 20 on each support part 101. Since the first locking structure 2 can lock the fixtures 20 on two adjacent support parts 101 at the same time, the fixture fixing efficiency can be improved. Since the fixture fixing mechanism 10 can fix multiple fixtures 20 at the same time, multiple fixtures 20 can be inspected at the same time, improving the inspection efficiency. Meanwhile, since the first locking structure 2 can rotate and limit the fixtures 20 on the two adjacent support parts 101, the placement of the fixtures 20 on the corresponding support parts 101 can be more precise, thereby improving the detection accuracy.

[0062] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
