A plurality of peripheral holes 4 are provided on the edge of the product carrying area 2, and the peripheral holes 4 are arranged on the periphery of the product carrying unit 3. The peripheral holes 4 are vacuum holes. A plurality of air nozzle interfaces 5 are provided on the bottom plate 1, and the air nozzle interfaces 5 are arranged around the product carrying area 2. The peripheral holes 4 are vacuum holes like the vacuum suction holes 32, and play the role of sucking the residual frame. The vacuum of the peripheral holes 4 and the vacuum suction holes 32 are designed separately, and the purpose of the separate design is to make it easy to suck and separate the product and the residual frame.

[0032] The air nozzle interface 5 is arranged around the product carrying area 2. The air nozzle interface 5 is used to connect the vacuum equipment and the device. Through the air nozzle interface 5, the vacuum equipment can transfer the suction force to the vacuum suction hole 32 and the peripheral hole 4, so as to realize the suction and fixation of the product and the residual frame. The design of the air nozzle interface 5 takes into account the sealing and stability to ensure the uniform transmission and effective effect of the suction force. At the same time, the installation position of the air nozzle interface 5 is also convenient for the staff to operate and maintain.

[0033] The depth of the slot 31 is greater than or equal to the thickness of the component, and the length, width and depth of the slot 31 are sized to avoid passive components.

[0034] The vacuum suction hole 32 is connected to the vacuum channel, and the vacuum channel is connected to the external air path, which is used to provide a vacuum effect when sucking the product. The opening size specification of the vacuum suction hole 32 is: avoiding the maximum size of the wall vacuum hole and the maximum vacuum design.

[0035] The shape of the slot 31 is circular, the diameter of the slot 31 is 1.00 mm, the distance between every two adjacent slots 31 in the X direction is 5.30 mm, and the distance between every two adjacent slots 31 in the Y direction is 2.20 mm.
