[0024] like Figure 1 、 3 As shown, the trimming mechanism 1 further includes a translation seat 13, a second cylinder 16, and a third cylinder 17. The translation seat 13 is connected to the translation mechanism, and the second cylinder 16 and the third cylinder 17 are both connected to the translation seat 13. The output end of the second cylinder 16 is provided with a knife seat 18 for mounting the trimming knife 11, and the output end of the third cylinder 17 is provided with a knife seat 2 19 for mounting the trimming knife 2 12. The trimming knife 11 and the trimming knife 2 12 are both arranged at an angle to the side of the glass assembly, and the inclination direction of the two is the same.

[0025] like Figure 1 、 4 As shown, the trimming mechanism 2 also includes a translation seat 22, a cylinder 4 23, and a trimming knife 3 24. The translation seat 22 is connected to the translation mechanism, and the cylinder 4 23 is fixed on the translation seat 22. The output end thereof is provided with a knife seat 3 24 for installing the trimming knife 3 21. The trimming knife 3 21 is also tilted to the side of the glass assembly.

[0026] Example 2

[0027] Based on the structure of Example 1, Figure 1 、 3 As shown, the trimming mechanism 1 also includes a cylinder 14 and a lifting seat 15. Cylinder 14 is fixed to translation seat 13, with the lifting seat 15 provided at its output end. Cylinders 2 16 and 3 17 are both located on the lifting seat 15 and connected to translation seat 13 via cylinder 14 and the lifting seat 15. The provision of cylinder 15 allows trimming mechanism 1 to avoid the entrance end of the glass assembly.

[0028] like Figure 1-4As shown, the trimming knife 11 and the trimming knife 3 21 have the same structure, including a plurality of arc-shaped trimming grooves 111. The plurality of trimming grooves 111 are arranged in the vertical direction on both sides of the knife body. The knife body is also provided with a long groove arranged in the vertical direction. The position of the trimming knife 11 and the trimming knife 3 21 can be adjusted so that different trimming grooves 111 are used, which has a long service life.

[0029] like Figure 1-3 As shown, the side of the second trimming blade 12 near the glass assembly is provided with a blade groove 121 that mates with the side of the glass assembly. Driven by the third cylinder 17, the blade groove 121 of the second trimming blade is locked to the side of the glass assembly.

The movable trimming blade 11 exits the trimming position, and the trimming blade 2 12, driven by the cylinder 3 17, advances close to the corner of the glass component; then the translation mechanism drives the trimming blade 2 12 to continue moving along the side, and the trimming blade 2 12 begins to remove the overflow glue layer at the corner chamfer position. When the trimming blade 2 12 advances and abuts against the trimming blade 3 21, the trimming blade 2 12 squeezes the trimming blade 3 21 under the action of the translation mechanism, causing the trimming blade 3 21 to retreat a distance. The two cooperate to completely remove the overflow glue layer at the corner of the glass component. In summary, the utility model has a simple structure and is easy to operate. It can simultaneously complete the secondary trimming of the side and corner chamfer positions, and does not need to be transferred to the next process for a second trimming, thereby improving production efficiency and reducing costs.
