[0043] Furthermore, the support frame 10 sets up the transfer mechanism 100 in the vertical direction. The support frame 10 is set up on the external conveying equipment for the packages.

The top support portion 32 and the bottom support portion 33 support the embedding portion 31, thereby improving the anti-deformation ability of the mounting portion 34, thereby improving the accuracy of transporting the package, reducing the alignment error before the two packages are attached, improving the alignment accuracy, and ensuring the bonding effect. In this embodiment, the embedding portion 31, the top support portion 32, the bottom support portion 33 and the mounting portion 34 are an integrated part to improve the bearing strength of the cross beam 30.

The energy absorption holes 35 on the top support portion 32 and the bottom support portion 33 are arranged symmetrically to ensure that the cross beam 30 is balanced and symmetrical up and down when decomposing internal stress, avoiding uneven stress distribution from generating torque at the joint between the cross beam 30 and the positioning plate 20, and ensuring the reliability of the connection between the cross beam 30 and the positioning plate 20.

[0047] Furthermore, the slide 40 is used to connect with an external component for grabbing the package to be bonded, and the slide 40 moves along the crossbeam 30 to perform a transfer operation on the package to be bonded.
