[0032] Please refer to Figures 1 to 4 The present application provides a kind of laser marking equipment's conjoined cover positioning mechanism, it include: positioning turntable 10 and compression assembly 20.

[0033] The positioning turntable 10 is provided with a plurality of positioning grooves 11, which are used for positioning cooperation with the cap 40 and the cover seat 41 of the integrated cover. The cap 40 and the cover seat 41 of the integrated cover can be arranged side by side in the positioning grooves 11 and are not easy to shake.

[0034] The pressing assembly 20 comprises a first pressing part 21, a second pressing part 22 and a driving assembly 23. The first pressing part 21 and the second pressing part 22 are drivingly connected with the driving assembly 23. The first pressing part 21 and the second pressing part 22 are driven by the driving assembly 23 to approach or move away from the positioning grooves 11. The first pressing part 21 is used for pressing the cover seat 41 of the integrated cover. The second pressing part 22 is used for pressing the cap 40 of the integrated cover. The first pressing part 21 and the second pressing part 22 can position the cover seat 41 and the cap 40 of the integrated cover, so that the cap 40 is not easily tilted relative to the cover seat 41 due to the elastic force, and the cap 40 can be accurately marked. The positioning grooves 11 can be adapted to position the cap 40 and the cover seat 41, so that the marking is facilitated, and the overall structure is simple.

[0035] It should be noted that the first pressing part 21 usually presses the cover seat 41 against the positioning turntable 10 or other support structures. However, due to the different thicknesses of the cap 40 and the cover seat 41, when the cap 40 is pressed by the second pressing part 22 to the positioning turntable 10 until the cap 40 reaches a suitable angle relative to the laser, the bottom of the cap 40 can not be in contact with the positioning turntable 10 and be in a suspended state. However, due to the elastic force at the connection between the cap 40 and the cover seat 41, a torsion force is applied to the cap 40 to turn it towards the cover seat 41. The torsion force can make the cap 40 tightly contact the second pressing part 22 and not be unstable due to the suspended state of the cap 40.

[0036] In some optional embodiments, the shape of the first pressing part 21 is adapted to the shape of the cover opening edge of the cover seat 41. The cover opening edge of the cover seat 41 is usually provided with a protruding guide ring 42 or other annular structure. The guide ring 42 is used for guiding the liquid to flow out of the cover opening. The shape of the first pressing part 21 is adapted to the edge of the cover seat 41, which can facilitate the pressing of the cover seat 41. In this embodiment, the first pressing part 21 is C-shaped, which can facilitate the stable pressing of the guide ring 42 of the cover seat 41.

[0037] In some optional embodiments, the second pressing part 22 comprises an intermediate pressing part 221, which is used to press against the joint between the cap 40 and the cover 41 of the integrated cover, which is usually elastic. The main reason for the cap 40 being tilted relative to the cover 41 is that the elastic force of the joint between the cap 40 and the cover 41 drives the cap 40 to flip towards the cover 41. Therefore, the shape of the joint between the cap 40 and the cover 41 can be effectively maintained by pressing the joint between the cap 40 and the cover 41 by the intermediate pressing part 221, so that the joint between the cap 40 and the cover 41 does not drive the cap 40 to tilt relative to the cover 41.

[0038] In some optional embodiments, the second pressing part 22 further comprises an arc-shaped auxiliary pressing part 222, one end of the auxiliary pressing part 222 is connected with the intermediate pressing part 221, and the intermediate pressing part 221 and the auxiliary pressing part 222 surround an avoiding gap 223 for laser passing, so that the intermediate pressing part 221 and the auxiliary pressing part 222 do not hinder the laser marking. In addition, a clamping groove is usually formed on the cap 40, so that part of the cover 41 is clamped into the clamping groove to cover the cap 40 and the cover 41. The auxiliary pressing part 222 adopts an arc-shaped structure, which can be well adapted to be pressed at the edge of the clamping groove of the cap 40, improve the positioning stability of the cap 40, and avoid the cap 40 from shaking.

[0039] In some optional embodiments, the pressing assembly 20 comprises a connecting part 24, which is connected with the first pressing part 21 and the second pressing part 22. The driving assembly 23 is drivingly connected with the first pressing part 21 and the second pressing part 22 through the connecting part 24, and the driving assembly 23 drives the first pressing part 21 and the second pressing part 22 to move together through the connecting part 24. The driving assembly 23 can be a pneumatic cylinder, a hydraulic cylinder or an electric cylinder. In the present embodiment, the driving assembly 23 is a pneumatic cylinder, and the output shaft thereof is connected with the connecting part 24.

[0040] In some optional embodiments, the integrated cover positioning mechanism of the laser marking device further comprises a limiting piece 30. The opening of the positioning groove 11 is located at the edge of the positioning turntable 10, and the limiting piece 30 is arranged around the positioning turntable 10. The limiting piece 30 is used to limit the integrated cover in the positioning groove 11, so as to avoid the integrated cover from being separated from the positioning groove 11 during laser marking.

[0041] In some optional embodiments, a plurality of positioning grooves 11 are arranged on the positioning turntable 10, and the plurality of positioning grooves 11 are arranged at the edge of the positioning turntable 10 and sequentially along the circumference of the positioning turntable 10, so as to facilitate the positioning turntable 10 to simultaneously position a plurality of integrated covers.

[0042] Please refer toFigure 5 In some optional embodiments, two sides of the positioning groove 11 are formed with a first arc-shaped positioning portion 12 and a second arc-shaped positioning portion 13, the first arc-shaped positioning portion 12 is used for positioning cooperation with the cover seat 41 of the integrated cover, and the second arc-shaped positioning portion 13 is used for positioning cooperation with the cover cap 40 of the integrated cover, so that after the cover seat 41 and the cover cap 40 are arranged side by side in the positioning groove 11, the cover seat 41 and the cover cap 40 can be stably positioned.

[0043] The integrated cover positioning mechanism of the laser marking equipment described above can be applied to a laser marking equipment, which comprises the integrated cover positioning mechanism of the laser marking equipment as described above.
