Description

Technical Field

[0002] The top and bottom covers of a mobile phone are secured with screws. During the installation process, if the screw holes at the four corners of the top and bottom covers are not aligned, the screws may scratch the phone's surface or even crush it.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figure 1-6 The fixing device shown is for an automatic screw fastening machine, including a processing table 1, a screw machine mechanism 2, two electric slide rails 3, two sets of first moving mechanisms 4, two sets of second moving mechanisms 5, two sets of placement mechanisms and two sets of clamping mechanisms 6.

[0025] Two electric slide rails 3 are fixedly connected to the worktable 1 near the left and right sides of the worktable 1, and the screw machine mechanism 2 is fixedly connected to the worktable 1 near the rear end. Two sets of first moving mechanisms 4 are respectively set on the two electric slide rails 3, two sets of second moving mechanisms 5 are respectively set on the two first moving mechanisms 4, two sets of placement mechanisms are respectively set on the two sets of second moving mechanisms 5, and two sets of clamping mechanisms 6 are respectively set on the two sets of placement mechanisms.

[0026] A feeding mechanism is fixedly connected to the middle of the worktable 1 near the front end, and the feeding mechanism is located directly below the screw machine mechanism 2.

[0027] Before use, place the upper and lower covers of the phone into the placement slot 71 and align the screw holes of the upper and lower covers. Then, rotate the rotating rod 61 to move the clamping plate 65 onto the phone cover and turn the rotating disc on the threaded rod 64 to move the clamping plate 65 downwards to press the upper and lower covers together and fix them in place, preventing them from shifting during screw fastening. After fixing the upper and lower covers, start the device. The moving part of the electric slide rail 3 (existing technology) drives the first moving mechanism 4 and the second moving mechanism 5 to move the upper and lower covers into the working range of the screw fastening mechanism 2 (existing technology). Then, start the screw fastening mechanism 2 to fasten the upper and lower covers with screws. In the assembly process, the feeding mechanism (existing technology) provides screws to the screw-making mechanism 2. When screw fastening is required for the upper and lower covers of mobile phones of different sizes, the first bidirectional lead screw 42 is rotated according to the size of the upper and lower covers, driving the two limit blocks 48 to move relative to each other or towards each other, adjusting the distance between the placement slots 71 on the front and rear side placement seats 7. Then, the second bidirectional lead screw 55 is rotated to drive the two moving blocks 56 to move relative to each other or towards each other, adjusting the distance between the placement slots 71 on the left and right side placement seats 7. This allows the size of the placement space in the placement slots 71 to be adjusted, enabling the screw fastening of the upper and lower covers of mobile phones of different sizes.

[0028] Each first moving mechanism 4 includes a fixed plate 41, two moving plates 43, four sliders 45, two limiting blocks 48, a first bidirectional lead screw 42, and two first bearings 49. The bottom of the fixed plate 41 is fixedly connected to the moving part of the electric slide rail 3. A rotating groove 47 is opened in the middle of the top of the fixed plate 41, and limiting grooves 44 are opened near the two sides of the top of the fixed plate 41. The two first bearings 49 are respectively embedded in the middle of the front and rear ends of the fixed plate 41, and both first bearings 49 communicate with the rotating groove 47. The positions of the first bidirectional lead screw 42 near both ends are fixedly connected to the inner rings of the two first bearings 49, and one end of the first bidirectional lead screw 42 faces the fixed plate. 41 extends forward, with two limiting blocks 48 slidably disposed within the rotating groove 47. Threaded holes are provided at the midpoint of both sides of each limiting block 48, and these threaded holes are threadedly connected to the first bidirectional lead screw 42 near both ends. The tops of both limiting blocks 48 extend outward from the rotating groove 47. The bottom midpoints of two moving plates 43 are fixedly connected to the tops of the two limiting blocks 48. A slider 45 is fixedly connected to the bottom near both sides of each moving plate 43, and each slider 45 is slidably connected to a corresponding limiting groove 44. Sliding grooves 46 are provided at the top near both sides of each moving plate 43. Each set of second moving mechanisms 5 includes... The system comprises a connecting block 51, a second bidirectional lead screw 55, two moving blocks 56, four sliding plates 52, and two second bearings 53. The connecting block 51 is fixedly connected to the top center of one of the moving plates 43. A moving groove 54 is formed in the center of the top of the connecting block 51. The two moving blocks 56 are slidably disposed in the moving groove 54, and the tops of the two moving blocks 56 extend out of the moving groove 54. The two second bearings 53 are respectively embedded in the middle of the left and right sides of the connecting block 51 and communicate with the moving groove 54. The two ends of the second bidirectional lead screw 55 are fixedly connected to the inner rings of the two second bearings 53, and one end of the second bidirectional lead screw 55 extends towards the connecting block 56. Extending to the right, threaded holes are provided at the middle positions of the left and right sides of the two movable blocks 56, and the threaded holes of the two movable blocks 56 are respectively threadedly connected to the second bidirectional lead screw 55 near both ends. A sliding plate 52 is slidably provided at the two sliding grooves 46 near both ends. Each set of placement mechanisms includes four placement seats 7, and each placement seat 7 has a placement groove 71 on its top. The four placement seats 7 form a rectangle after they abut each other, and the four placement grooves 71 form a complete rectangular groove. The middle position of the bottom of each placement seat 7 is fixedly connected to the top of a movable block 56, and the middle position of the bottom of each placement seat 7 near both the front and rear ends is fixedly connected to the top of the corresponding two sliding plates 52.

[0029] When screwing together the top and bottom covers of mobile phones of different sizes, the rotation of the first bidirectional lead screw 42 is performed according to the size of the top and bottom covers. The first bearing 49 facilitates the rotation of the first bidirectional lead screw 42. Under the limiting action of the rotation groove 47 and the threaded hole of the limiting block 48, the rotation of the first bidirectional lead screw 42 drives the two limiting blocks 48 to move relative to or towards each other, thereby driving the two moving plates 43 to move relative to or towards each other, thus adjusting the distance between the placement grooves 71 on the front and rear side placement seats 7. At this time, the slider 45 moves within the limiting groove 44, limiting the movement of the moving plate 43 to prevent it from shifting, and supporting the moving plate 43 to increase its support area and improve its stability. After adjustment, the second bidirectional lead screw 55 is rotated, and the second bearing... 53 facilitates the rotation of the second bidirectional lead screw 55. Under the action of the moving groove 54 and the threaded hole on the moving block 56, the rotation of the second bidirectional lead screw 55 drives the two moving blocks 56 to move relative to each other or towards each other, thereby driving the two placement seats 7 at the same level to move relative to each other or towards each other, realizing the adjustment of the distance between the placement grooves 71 on the left and right placement seats 7. At this time, the sliding plate 52 moves in the sliding groove 46, limiting the placement seat 7 while supporting the placement seat 7, improving the stability of the placement seat 7. When the four placement seats 7 are separated, the placement grooves 71 can be used to put mobile phone top and bottom covers of different sizes, realizing the screw fastening installation of mobile phone top and bottom covers of different sizes. After the screw fastening installation is completed, the first bidirectional lead screw 42 and the second bidirectional lead screw 55 are rotated in the opposite direction, making it easy to remove the mobile phone cover.

[0030] Each pressing mechanism 6 includes four rotating pressing components. Each rotating pressing component includes a rotating rod 61, a support column 62, a third bearing 63, a threaded rod 64, a pressing plate 65, and a fourth bearing 66. The bottom of the support column 62 is fixedly connected to the top of one of the placement seats 7 near the side. The inner ring of the third bearing 63 is fixedly fitted on the support column 62 near the top. The rotating rod 61 is fixedly fitted on the outer ring of the third bearing 63 near one end. A threaded hole is opened at the other end of the rotating rod 61. The threaded rod 64 is threadedly connected to the threaded hole. The fourth bearing 66 is embedded in the middle of the top of the pressing plate 65. The inner ring of the fourth bearing 66 is fixedly connected to the bottom end of the threaded rod 64, and a rubber anti-slip pad is fixedly connected to the bottom of the pressing plate 65. The two pressing components at the same horizontal position are symmetrically arranged.

[0031] After the top and bottom covers of the phone are in place, rotate the rotating rod 61. The support column 62 supports the rotating rod 61, and the third bearing 63 facilitates the rotation of the rotating rod 61. Rotate the pressing plate 65 above the phone cover. Then rotate the threaded rod 64. Under the action of the threaded hole, the threaded rod 64 drives the pressing plate 65 to move down and contact the phone cover. Under the action of the fourth bearing 66, continuing to rotate the threaded rod 64 will make the pressing plate 65 press tightly against the phone cover. The rubber anti-slip pad increases the friction between the pressing plate 65 and the phone cover, preventing damage to the phone surface caused by the top and bottom covers not being fixed firmly.

[0032] Rotary discs are fixedly connected to the extension ends of the two first bidirectional lead screws 42, the two second bidirectional lead screws 55, and the tops of the multiple threaded rods 64.

[0033] The rotating disc facilitates the rotation of the first double-acting lead screw 42, the second double-acting lead screw 55, and the threaded rod 64.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
