[0022] 2.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0030] Example: Reference Figure 1-4 The offline automatic glass frame inversion device shown in the figure comprises a basic frame 1, a moving trolley group 2 moving along the basic frame 1 is arranged on the basic frame 1, an adjustable metal arm 3 is installed at the lower end of the moving trolley group 2, a suction cup group 4 is installed at the lower end of the adjustable metal arm 3 through an adjustment structure, and a glass frame group 5 is also arranged below the basic frame 1;
[0031] The lower end of the adjustable metal arm 3 is provided with a mounting clamp seat 6 driven to rotate by the adjustment structure. The mounting clamp seat 6 is fixed to the rear side of the suction cup group 4 through a connecting piece. The connecting piece can be a connecting element commonly used in the prior art and suitable for this embodiment, such as a connecting shaft. An ear plate 61 is fixed to the periphery of the mounting clamp seat 6.
[0032] The outer cover of the mounting clamp seat 6 is provided with a protective shell 7 rotatably connected to the adjustable metal arm 3, a limiting hole 72 is provided in the middle of the protective shell 7, and the ear plate 61 is located in the limiting hole 72;
[0033] A damping and limiting structure is installed in the protective shell 7. When the ear plate 61 rotates, it contacts the damping and limiting structure and is buffered and limited by the damping and limiting structure.
[0034] Based on the above structure, when the mounting clamp 6 is driven to rotate by the adjustment structure, the ear plate 61 rotates accordingly and contacts the damping limit structure, is buffered by the damping limit structure, and is finally limited by the damping limit structure, so that the mounting clamp 6 can be quickly decelerated by the damping structure when performing the initial rotation, so that it can start to rotate slowly, avoiding sudden acceleration that causes a large relative displacement between the suction cup group 4 and the glass, resulting in unstable adsorption or glass detachment, glass tilt, etc.
[0035] Furthermore, the damping limit structure includes:
[0036] The medium cavity 71 is provided in the middle of the protective shell 7 and adjacent to the limiting hole 72, and is provided in the suction cup group 4 on the peripheral side wall;
[0037] The partition plate 73 is provided with a plurality of partition plates 73 and divides the medium cavity 71 into two closed chambers. A through hole connecting the two closed chambers is provided on the partition plate 73 in the middle of the two closed chambers. The two closed chambers are filled with a liquid buffer medium, and the liquid buffer medium adopts a liquid medium commonly used in the prior art and suitable for this embodiment, such as water, oil, etc.;
[0038] The limiting slide bar 9 is provided with a plurality of partition plates 73 which slide through both ends of the medium cavity 71, respectively. The sliding direction of the limiting slide bar 9 is the same as the circumferential direction of the protective housing 7;
[0039] The pressing plate 92 is fixed to the end of the limiting sliding rod 9 located in the medium cavity 71 . The cross section of the pressing plate 92 is the same as that of the medium cavity 71 . The pressing plate 92 is slidably connected to the inner wall of the medium cavity 71 .
[0040] The liquid buffer medium filled in the two closed chambers can pass through the gap between the pressing plate 92 and the inner wall of the medium chamber 71;
[0041] A clamping plate 91 is fixed to one end of the limiting sliding rod 9 located outside the medium cavity 71 , and two adjacent clamping plates 91 cooperate to clamp the ear plates 61 .
[0042] When the ear plate 61 rotates with the mounting clamp 6, the ear plate 61 first contacts the card plate 91, driving the card plate 91 to move. When the card plate 91 moves, the pressure plate 92 is driven to move synchronously through the limit slide bar 9, so that the pressure plate 92 slides in the medium cavity 71, and the liquid buffer medium in the medium cavity 71 is squeezed and surges through the gap between the pressure plate 92 and the medium cavity 71. Since the gap between the pressure plate 92 and the medium cavity 71 is small, the liquid buffer medium passes slowly and plays a damping role, thereby preventing the pressure plate 92 from moving too fast in the medium cavity 71, thereby preventing the ear plate 61 in contact with the card plate 91 and the mounting clamp 6 from rotating at a faster speed in the initial stage, thereby preventing sudden acceleration from causing a large relative displacement between the suction cup group 4 and the glass, resulting in unstable adsorption or glass detachment, glass tilt, etc.
[0043] Furthermore, a return spring 93 is fixed to one side of the pressure plate 92, and the other end of the return spring 93 is fixed to one side of the partition plate 73 in the middle of the medium chamber 71. After the rotation is completed, the clamping plate 91 is not compressed by the ear plate 61, and the elastic force of the return spring 93 pushes the pressure plate 92 to slowly return to its original position, thereby facilitating the damping and buffering of the mounting clamp 6 during the next start-up.
[0044] Furthermore, an elastic airbag 8 is fixed to the rear side of the protective shell 7, and the elastic airbag 8 fills the gap between the rear side of the protective shell 7 and the inner wall of the adjustable metal arm 3. Through the provision of the elastic airbag 8, the friction between the protective shell 7 and the inner wall of the adjustable metal arm 3 can be increased, thereby avoiding the situation where the protective shell 7 itself is initially subjected to force and immediately rotates due to the rotation connection to the adjustable metal arm 3, thereby ensuring that the damping limit structure plays a good buffering role. Secondly, it can also provide a certain buffer space between the protective shell 7 and the inner wall of the adjustable metal arm 3, so that the protective shell 7 will not be damaged due to a hard collision when it is hit by an external impact.
[0045] Working principle of the utility model: in daily use, when the mounting clamp 6 is driven to rotate by the adjustment structure, the ear plate 61 rotates accordingly, and the ear plate 61 first contacts with the card plate 91, driving the card plate 91 to move. When the card plate 91 moves, the pressure plate 92 is driven to move synchronously through the limit slide bar 9, so that the pressure plate 92 slides in the medium cavity 71, and the liquid buffer medium in the medium cavity 71 is squeezed and surges through the gap between the pressure plate 92 and the medium cavity 71. Since the gap between the pressure plate 92 and the medium cavity 71 is small, the liquid buffer medium passes slowly and plays a damping role, thereby preventing the pressure plate 92 from moving too fast in the medium cavity 71, thereby preventing the ear plate 61 in contact with the card plate 91 and the mounting clamp 6 from rotating at a faster speed in the initial stage, thereby preventing sudden acceleration from causing a large relative displacement between the suction cup group 4 and the glass, resulting in unstable adsorption or glass detachment, glass tilt, etc.
[0046] Finally, it should be noted that the above 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 aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
