[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0041] Example 1

[0042] Please refer to Figure 1 , a tool for removing OCA, comprising a head bonding part 1, used for the adhesion of OCA colloids; the head bonding part 1 is hemispherical; a finger gripping part 2, used for the operator to apply force with his fingers; the finger gripping part 2 is integrally connected with the head bonding part 1; the finger gripping part 2 is in a rectangular parallelepiped shape, and the finger gripping part 2 is located in the middle of the circular cross-section of the hemispherical head bonding part 1; the finger gripping part 2 and the outer wall of the head bonding part 1 are both provided with an anti-slip part; further, the anti-slip part can be made of concave and convex points, dents, grid marks, frosting, etc., or can be made of a rubber sleeve or rubber strip with a certain friction force, etc.

[0043] The present embodiment provides a tool for removing OCA. When the operator pinches the finger gripping part 2 with the thumb and index finger and pokes the head bonding part 1 toward the main screen or the cover plate, the circular cross-section of the head bonding part 1 can block the thumb and the index finger, and at the same time, the head bonding part 1 transmits the thrust to the thumb and the index finger, so that the head bonding part 1 can smoothly bond the adhesive mass on the main screen or the cover plate, etc.; the convenience of operation is improved; and the rectangular shape can facilitate the operator's fingers to grip the finger gripping part 2; the anti-slip part at the finger gripping part 2 can increase the grip between the operator's fingers and the finger gripping part 2, and the anti-slip part at the head bonding part 1 can increase the friction between the head bonding part 1 and the OCA adhesive mass.

[0044] Specifically, the size of the finger gripping portion 2 is 10 mm*10 mm. The width is close to the width of a human thumb, which is convenient for an operator to grip the finger gripping portion 2 with his fingers without wasting materials.

[0045] Example 2

[0046] The tool for removing OCA provided in Example 1 is further optimized, specifically, as follows: Figure 4 As shown, it also includes a reinforcing plate 3 built into the head adhesive portion 1 and the finger gripping portion 2; further, the reinforcing plate 3 is preferably a metal plate with a certain rigidity, and a wooden plate or a plastic plate can also be used; more specifically, the head adhesive portion 1 and the finger gripping portion 2 can be made of plastic rubber material.

[0047] The tool for removing OCA provided in this embodiment can improve the connection strength between the head adhesive portion 1 and the finger gripping portion 2 through the above configuration, thereby avoiding excessive bending of the finger gripping portion 2 during use, and making the tool have a certain strength.

[0048] Example 3

[0050] The present embodiment provides a tool for removing OCA. An operator can remove the OCA glue mass on the main screen or cover plate by holding the handle portion 4. Compared with holding the finger grip portion 2 with the thumb, the handle portion 4 is easier for the operator to apply force, and the OCA removal tool can be used more conveniently and labor-savingly; the U-shaped opening 6 can allow the operator's thumb to pass through, so as to facilitate the disassembly and assembly of the finger grip portion 2 from the embedding box 5; the handle portion 4 can be selected according to the use requirements, and the finger grip portion 2 can be detachably installed in the embedding box 5 to conveniently disassemble and assemble the finger grip portion 2 and the embedding box 5; and the soft strip protrusion 8 can improve the connection tightness between the finger grip portion 2 and the inner wall of the embedding box 5 to prevent the finger grip portion 2 from detaching from the embedding box 5 during use.

[0051] Example 4

[0052] The tool for removing OCA provided in Example 3 is further optimized, such as Figure 4-5As shown, a rotating disk 9 is rotatably installed at the end of the handle portion 4, and the embedded box 5 is fixedly installed on the rotating disk 9. The handle portion 4 has a built-in driving component for driving the rotating disk 9 to reciprocate.
