[0029] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0030] Reference Figure 1-8 , which is the first embodiment of the utility model, provides a quality inspection device for shielding cover production, the quality inspection device for shielding cover production comprises a bracket 1, a detection head 2 and a detection platform 3 installed on the surface of the bracket 1, the detection head 2 is located on one side of the detection platform 3, an expansion piece 4 is installed inside the detection platform 3, a movable platform 5 is installed on the surface of the bracket 1 and on both sides of the detection platform 3, and a positioning piece 6 is installed on the top of the movable platform 5;

[0031] The expansion member 4 includes an expansion plate 45 movably sleeved inside the testing platform 3, and the surfaces of the expansion plate 45 and the testing platform 3 are both installed with equidistantly arranged rubber plates 43, and the surfaces of the rubber plates 43 are installed with equidistantly arranged rubber blocks 44, and the surface of the testing platform 3 is provided with equidistantly arranged grooves 41, and the rubber plates 43 on the surface of the expansion plate 45 are located inside the grooves 41 and are movably connected thereto, and the rubber plates 43 on the surfaces of the testing platform 3 and the expansion plate 45 are staggered, and the heights of the two are consistent, even if a longer shielding cover is installed on its surface, the shielding cover will not become unstable due to the height difference problem, and the setting of the rubber plates 43 and the rubber blocks 44 can increase the friction between the shielding cover, so that the shielding cover can be more stable on the surfaces of the testing platform 3 and the expansion plate 45, and the displacement caused by shaking can be prevented, and since the testing platform 3 and the expansion plate 45 are movably connected, the length of the testing platform 3 can be increased by moving the expansion plate 45 toward the two sides of the testing platform 3, thereby avoiding the need to replace the testing platform 3 when testing a longer shielding cover.

[0032] A slide groove 42 is provided on the inner side of the detection platform 3, and slide bars 46 are fixedly connected to both sides of the expansion plate 45. The slide bar 46 is located inside the slide groove 42 and is movably connected to it. A connecting piece 47 is provided at one end of the expansion plate 45. The setting of the slide groove 42 and the slide bar 46 can make the expansion plate 45 move more stably along the inside of the detection platform 3 to its both sides.

[0033] The connecting member 47 includes a connecting hole 471 opened on the surface of the expansion plate 45, and the connecting hole 471 is located at one end away from the detection platform 3. Connecting plates 472 are fixedly connected to both sides of the movable platform 5. Cavities 473 are opened on the inner sides of the movable platform 5 and the connecting plates 472. The expansion plate 45 is located inside the cavity 473 and is movably connected thereto. The setting of the cavity 473 can facilitate the connection of the expansion plate 45 to reduce the error of the positioning member 6.

[0034] A supporting plate 474 is fixedly connected to both sides of the movable platform 5 and located at the bottom of the connecting plate 472. A connecting bolt 475 is movably connected inside the supporting plate 474. The expansion plate 45 and the connecting plate 472 are connected through the connecting bolt 475. A hole with the same diameter as the connecting hole 471 is opened inside the connecting plate 472, and a supporting groove for supporting the connecting bolt 475 is opened inside the supporting plate 474. The connecting bolt 475 passes through the hole and the connecting hole 471 and penetrates the connecting plate 472 and the expansion plate 45, and its bottom extends to the supporting groove inside the supporting plate 474, so that the expansion plate 45 can be connected to the movable platform 5.

[0035] The positioning member 6 includes a positioning plate 61 located on the top of the movable platform 5, and a rotating shaft 62 is fixedly connected inside the positioning plate 61. Both ends of the rotating shaft 62 are located on the inner side of the movable platform 5 and are movably connected thereto. A positioning block 63 is fixedly connected to one end of the positioning plate 61, and rubber strips 64 arranged equidistantly are installed at the bottom of the positioning block 63. The rubber strips 64 can increase the friction between the rubber strips 64 and the shielding cover, making it more stable. At the same time, a triangular plate is installed on the top of the movable platform 5, which is an integral structure with the movable platform 5. The rotating shaft 62 is located inside the triangular plate and connected thereto, and the rotating shaft 62 is located at one-third of the positioning plate 61, so that it can form an inclined state through its own gravity.

[0036] The internal thread of the positioning plate 61 is connected with a bolt 65, and the bolt 65 is located at the end away from the positioning block 63. A steering ball 66 is provided at the bottom of the positioning plate 61. The bottom of the bolt 65 extends to the bottom of the positioning plate 61 and is connected to the steering ball 66. The bolt 65 is used to drive the angle adjustment of the positioning plate 61, and a connecting rod is installed between the bolt 65 and the steering ball 66. The bolt 65 is fixedly connected to the connecting rod, and the connecting rod is movably connected to the steering ball 66, which can facilitate the rotation of the bolt 65 and prevent the connecting rod from separating from the steering ball 66.

[0037] A steering groove 67 and a reserved groove 68 are provided on the surface of the movable platform 5 and at the bottom of the positioning plate 61. There are two groups of reserved grooves 68, which are respectively located on both sides of the steering groove 67. The reserved grooves 68 are communicated with the steering groove 67. The steering ball 66 is located inside the steering groove 67 and is movably connected to the steering groove 67. The diameter of the reserved groove 68 is larger than that of the connecting rod, which can prevent the connecting rod from getting stuck. The setting of the reserved groove 68 can facilitate the change of the position of the connecting rod and facilitate the movement of the bolt 65.

[0038] The movable platform 5 is internally rotatably connected with a screw 691, one end of which extends to the outside of the bracket 1, and the surface of the screw 691 is threadedly connected with a slider 69, which is located inside the bracket 1 and movably connected thereto. A guide groove 692 is provided on the surface of the bracket 1, and the slider 69 extends to the surface of the bracket 1 through the guide groove 692 and is fixedly connected to the movable platform 5. The screw 691 is used to drive the movement of the slider 69 and drive the movable platform 5 to move at the same time. In this way, the distance between the two groups of movable platforms 5 can be adjusted according to the length of the shielding cover, thereby driving the expansion plate 45 to move toward both sides of the detection platform 3.

[0039] During use, if it is necessary to test a slightly longer shielding cover, first pull the expansion plate 45 to allow the rubber plate 43 and the rubber block 44 on its surface to slowly move toward the two sides of the test bench 3 along the inside of the groove 41, until the expansion plate 45 is pulled to the inside of the cavity 473 inside the movable table 5 and the connecting plate 472, and then extend the connecting bolt 475 through the hole inside the connecting plate 472 to the inside of the connecting plate 472, and penetrate the expansion plate 45 through the connecting hole 471, so that the bottom of the connecting bolt 475 is located inside the supporting groove on the surface of the bearing plate 474, so that the expansion plate 45 can be connected to the movable table 5, so that shielding covers of different lengths can be tested, avoiding the need to replace the test benches 3 of different lengths when testing shielding covers of different lengths, and further reducing the time and manpower for replacing the test benches 3;

[0040] Then, according to the length of the shielding cover, the screw rod 691 is rotated to make the slider 69 slowly move toward the end away from the detection platform 3 along the rotation of the screw rod 691. After the adjustment is completed, the bolt 65 is rotated again to drive the connecting rod to rotate along the inside of the steering ball 66, so as to drive the positioning plate 61 to slowly flip through the rotating shaft 62, so that the distance between the positioning block 63 and the shielding cover becomes smaller and smaller, until the rubber strip 64 at the bottom of the positioning block 63 is in close contact with the shielding cover to complete the fixing of the shielding cover. In this process, the steering ball 66 will rotate inside the steering groove 67 due to the rotation of the bolt 65, and the bolt 65 will also slowly adjust the angle between it and the movable platform 5. When the positioning plate 61 is perpendicular to the movable platform 5, the bolt 65 forms a right angle with the movable platform 5. When the positioning plate 61 and the movable platform 5 form an acute angle, that is, when the positioning block 63 and the movable platform 5 form an acute angle, the bolt 65 and the movable platform 5 are in an inclined state, so that it can avoid being stuck with the positioning plate 61, so that the error generated during the detection process can be avoided, thereby improving the accuracy of the detection and ensuring that it meets the quality standards and specification requirements.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
