Description

Technical Field

[0001] The utility model belongs to the technical field of silicon polishing sheet processing, in particular to a portable non-destructive sheet taking tool. Background Art

[0002] In the field of silicon polishing wafer processing, silicon wafers need to be frequently picked up and placed. Manual picking and placing can easily cause cuts on the edges of silicon wafers. Therefore, silicon wafer manufacturers use vacuum suction pens to operate, but the following problems may occur:

[0003] During the wafer processing, a lot of silicon powder and mud will be generated, which will flow along the vacuum pipes of the suction pen and the factory vacuum pipes. Long-term use will damage the vacuum system or even completely block the vacuum system and cause the factory to stop production; the vacuum pipes need to be disassembled to clean, which is very troublesome; there are many wafer processing areas in the factory, and almost every position requires a suction pen to take the wafers, but the vacuum system obviously cannot divide so many branches, so a wafer taking tool is urgently needed. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a portable non-destructive film taking tool. The pipeline and the air bag are easy to clean and replace, and the disassembly is simple and convenient. The tool is convenient to carry and does not require a vacuum system, thus saving costs.

[0005] The utility model is realized by the following technical solutions:

[0006] A portable non-destructive wafer taking tool comprises a suction cup for adsorbing silicon wafers, a hand-held rod is horizontally arranged below the suction cup, and an air bag is arranged in the inner cavity of the hand-held rod;

[0007] The airbag is located in the inner cavity of the hand-held rod, and the air outlet at one end close to the suction cup is tightly matched with the bottom of the suction cup through the airbag connecting pipe. The top of the airbag passes through the outer wall of the hand-held rod and extends to the outside of the hand-held rod. A square tube is horizontally arranged above the airbag, and a compression spring is arranged between the bottom of the end of the square tube away from the airbag and the hand-held rod;

[0008] The square tube is a structure with solid rods at both ends and a hollow middle. The middle hollow part forms a hollow airway for pressing. The two ends of the middle hollow part respectively extend to the outer wall of the square tube with openings I and II. The opening I faces downward for connection with the air inlet of the airbag, and the opening II faces upward for finger pressing. The end of the square tube close to the suction cup is connected to an inclined connecting rod through a solid rod, and the other end of the connecting rod is connected to the hand-held rod.

[0009] Furthermore, the suction cup is a silicone suction cup.

[0010] Furthermore, spring fixing mechanisms are arranged at intervals above and below the outside of the compression spring.

[0011] Furthermore, the spring fixing mechanism includes spring fixing blocks respectively connected to the bottom of the square tube and to the top of the hand-held rod.

[0012] Furthermore, a pressing sealing ring is provided at the opening II.

[0013] Furthermore, the solid rod is threadedly connected to the connecting rod.

[0014] Furthermore, one end of the airbag connecting pipe is tightly connected to the airbag.

[0015] Furthermore, the square tube composed of the solid rod and the pressed hollow airway is an integral casting structure.

[0016] Furthermore, the length of the compression spring after rebounding ensures that the tube and the hand-held rod remain parallel under normal pressure.

[0017] Furthermore, the other end of the connecting rod is connected to both sides of the hand-held rod by a retaining spring.

[0018] The beneficial effects of the utility model are:

[0019] When the device is in operation, the user holds the hand-held rod, presses the pressing seal ring and the hollow airway to shrink the compression spring, so that the airbag becomes smaller and the rubber suction cup contacts the silicon wafer. The finger is not subjected to force but still contacts the pressing seal ring. The compression spring rebounds to generate suction pressure, which acts on the silicon wafer through the airbag connecting pipe, thereby sucking the silicon wafer. At this time, the finger is also sucked on the pressing seal ring by the suction force. When releasing, the finger moves away from the pressing seal ring to reduce the suction pressure and release the silicon wafer.

[0020] The device is simple and convenient for taking and placing silicon wafers, easy to operate, and the pipeline and air bag of the device are easy to clean and replace, easy to disassemble, easy to carry, and does not require a vacuum system, thus saving costs.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0026] As shown in the figure, a portable non-destructive wafer removal tool comprises a suction cup 1 for adsorbing a silicon wafer 2, wherein the suction cup 1 is a silicone suction cup, a hand-held rod 11 is horizontally arranged below the suction cup 1, and an air bag 4 is arranged in the inner cavity of the hand-held rod 11;

[0027] The airbag 4 is located in the inner cavity of the hand-held rod and the air outlet at one end close to the suction cup is tightly matched with the bottom of the suction cup 1 through the airbag connecting pipe 3, which is elastically fixed by the rubber suction cup; the other end of the airbag connecting pipe 3 is tightly connected to the airbag 4 and is elastically fixed by the airbag; the top of the airbag 4 extends through the outer wall of the hand-held rod to the outside of the hand-held rod 11, and a square tube 12 is horizontally arranged above the airbag 4, and a compression spring 8 is arranged between the bottom of the end of the square tube 12 away from the airbag and the hand-held rod 11; the length of the compression spring 8 after rebounding ensures that the tube 12 and the hand-held rod 11 remain parallel under normal pressure.

[0028] Furthermore, spring fixing mechanisms are arranged at intervals above and below the compression spring 8 .

[0029] The spring fixing mechanism includes a spring fixing block 9 connected to the lower side of the square tube 12 and the upper side of the hand-held rod 11 respectively.

[0030] The square tube 12 is a structure with solid rods 7 at both ends and a hollow structure in the middle. The hollow part in the middle forms a pressing hollow airway 6. The square tube composed of the solid rod 7 and the pressing hollow airway 6 is an integral casting structure. The two ends of the middle hollow part extend to the outer wall of the square tube with openings I and II respectively. The opening I is downward and used to be tightly connected with the air inlet of the airbag 4 and is fixed by the elasticity of the airbag; the opening II is upward and used for finger pressing. The opening II is on the same side as the compression spring 8. A pressing sealing ring 10 is provided at the opening II. The end of the square tube 12 close to the suction cup is connected to an inclined connecting rod 5 through a solid rod 7. The solid rod 7 is threadedly connected to the connecting rod 5. The other end of the connecting rod 5 is connected to both sides of the hand-held rod 11 by a retaining spring.

[0031] Working process:

[0032] During operation, the user holds the handle 11, presses the pressing sealing ring 10 and presses the hollow airway 6 to shrink the compression spring 8, so that after the airbag 4 becomes smaller, the rubber suction cup 1 contacts the silicon wafer, but the finger is not under force but still contacts the pressing sealing ring 10. The compression spring 8 rebounds to generate suction pressure, which acts on the silicon wafer 2 through the airbag connecting pipe 3 to make the rubber suction cup 1 act on the silicon wafer 2 and suck the silicon wafer 2. At this time, the finger is also sucked on the pressing sealing ring 10 by the suction force; when releasing, the finger moves away from the pressing sealing ring 10 to reduce the suction pressure and then release the silicon wafer 2.
