[0016] The device will be further described in detail below with reference to the embodiments of the drawings.

[0017] As shown in the figure, an adhesive bonding device for a transparent plastic box includes a box body 1 and two corner positioning blocks 2 symmetrically fixed inside the box body 1. An upper pressing block 3 and a side pressing block 4 are respectively arranged above and outside the corner positioning blocks 2. A pressing block driving mechanism is provided inside the box body 1, comprising a first cylinder 5 and a second cylinder 6. The first cylinder 5 is vertically fixed inside the box body 1 and located above the corner positioning blocks 2. The piston rod of the first cylinder 5 is fixed to the upper pressing block 3 to drive the upper pressing block 3 to move up and down. The second cylinder 6 is horizontally fixed inside the box body 1 and located outside the corner positioning blocks 2. The piston rod of the second cylinder 6 is fixed to the side pressing block 4. The pressure block 4 is fixed to drive the side pressure block 4 to move horizontally left and right; the corner positioning block 2 is provided with a lamp bead mounting cavity 21 with an open top. The lamp bead mounting cavity 21 is conical and the inner surface is reflective, which increases the curing area of ​​the UV lamp and concentrates the light. The lamp bead mounting cavity 21 is provided with a UV lamp bead 7. The box 1 is provided with a UV power supply 8. The UV lamp bead 7 is electrically connected to the UV power supply 8. The front side of the box 1 is provided with an acrylic protective plate 9 that slides up and down with it. The box 1 is fixedly provided with a rodless cylinder 10. The slider of the rodless cylinder 10 is fixed with the acrylic protective plate 9 to drive the acrylic protective plate 9 to move up and down.

[0018] In the above embodiments, the corner positioning block 2 is made of black acrylic, which can provide the first layer of protection against ultraviolet rays emitted by the UV lamp bead 7. Then, during UV curing, the corner positioning block 2 is blocked by the acrylic protective plate 9, which can provide the second layer of protection against ultraviolet rays emitted by the UV lamp bead 7. In addition, the upper pressure block 3 and the side pressure block 4 can both be made of acrylic to prevent damage to the box body or the box cover 11 when pressed.

[0019] The bonding process of this utility model for curing transparent plastic boxes is as follows: Two corners of one end of the box body or lid 11, bonded with UV glue, are placed on the corner positioning block 2. Then, the first cylinder 5 and the second cylinder 6 are controlled to drive the upper pressure block 3 and the side pressure block 4 respectively to press the corners of the box body or lid 11. Then, the rodless cylinder 10 drives the acrylic protective plate 9 downwards to block the corner positioning block 2. Next, the UV power supply 8 is turned on, and the UV lamp beads 7 installed in the corner positioning block 2 emit ultraviolet light to cure the bonded corners of the box body or lid 11. After curing, the rodless cylinder 10 drives the acrylic protective plate 9 upwards, and the first cylinder 5 and the second cylinder 6 respectively drive the upper pressure block 3 and the side pressure block 4 to loosen the box body or lid 11. After removing the box body or lid 11, the other end is placed on the corner positioning block 2. The above process is repeated until the curing of the entire bonded corner of the box body or lid 11 is completed.
