Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, 2 and 3, a blue film cutting device for SIP product testing includes: the cutter arbor 1 and the annular cutting edge 2 of protrusion setting cutter arbor one end, annular cutting edge 2 encloses into blue membrane and holds chamber 3, and the shape and size that blue membrane held chamber 3 is the same with the shape and size of required blue membrane. When cutting the blue membrane of required shape, hold the cutter arbor, annular cutting edge 2 aligns the blue diaphragm of tiling, presses hard and can surely go out the blue membrane of required shape, compares in prior art and just leans on the manual work to cut out required blue membrane, and this application can cut out required blue membrane fast, and cutting efficiency is high, and the blue membrane shape and size of cutting out is more accurate.

Since the cut blue film has a high probability of remaining in the blue film accommodating chamber 3, the blue film needs to be ejected quickly. The cutter arbor 1 is equipped with the top membrane hole 13 that sets up along its length direction, and top membrane hole 13 communicates with each other with blue membrane holds chamber 3, is equipped with the top membrane pole 4 that can follow the motion of cutter arbor 1 length direction in the top membrane hole 13, and top membrane pole 4 is arranged in ejecting blue membrane and holds the blue membrane in the chamber 3.

Further, the length of the top film rod 4 is larger than the sum of the length of the top film hole 13 and the depth of the blue film accommodating cavity 3.

Still further, because the top film rod 4 is too thin and is not easy to hold, the end of the top film rod 4 extending out of the cutter bar 1 is provided with a handle 41 with a larger size, which is convenient to hold, and preferably, the handle 41 is a square block or a round block, etc.

Furthermore, one end of the top film rod 4, which is used for pushing the blue film, is provided with a flexible protection block 42, such as a sponge block, a rubber block and the like, so that the blue film is prevented from being damaged by pushing.

Wherein, cutter arbor 1 includes the transition portion 12 that holds 11 and be located 11 one ends of holding, and annular cutting edge 2 locates transition portion 12, and the top membrane hole 13 is located on holding 11 and transition portion 12, by holding 11 to annular cutting edge 2, transition portion 12 contracts gradually.

Because required blue membrane size is different, and the shape is different, needs different annular cutting edge 2, for change annular cutting edge 2, transition portion 12 adopts the mode that can dismantle fixed connection to install on the portion 11 of gripping to conveniently change different annular cutting edge 2. If the holding part 11 is provided with a threaded hole, the transition part 12 is provided with a stud matched with the threaded hole, the transition part 12 is fixed on the holding part 11 in a threaded connection mode, or the holding part 11 and the transition part 12 are connected in a clamping connection mode, one of the holding part 11 and the transition part 12 is provided with a clamping protrusion, and the other one is provided with a clamping hook matched with the clamping protrusion.

Preferably, the grip portion 11 has a cylindrical or square cylindrical shape for easy gripping.

The foregoing is illustrative of the best mode of the invention, and details not described herein are within the common general knowledge of a person of ordinary skill in the art. The protection scope of the present invention is subject to the content of the claims, and any equivalent transformation based on the technical teaching of the present invention is also within the protection scope of the present invention.
