Description

Technical Field

[0001] The utility model relates to the technical field of suction clamps, and more specifically to a silicone film suction clamp. Background Art

[0002] A keyboard is a device for inputting commands and data to operate a device. It also refers to a group of function keys that are arranged by a system to operate a machine or device. Keyboards can be divided into contact type, non-contact type, and laser type.

[0003] When people use computers in daily life, they will inevitably use them together with keyboards. Due to the design of the keyboard structure, dust is easy to accumulate inside, and the dust is difficult to clean. Long-term dust accumulation may cause damage to the electronic components inside the keyboard. At this time, people will use dust-proof silicone covers to protect the keyboard from dust. Since the dust-proof silicone covers are often extruded by extrusion equipment, this will cause the dust-proof silicone covers to fit too tightly to the mold after extrusion. At this time, the operator needs to use a suction cup to remove it. Although this method can easily separate the silicone cover from the mold, due to the excessive suction force of the suction cup, the subsequent operator needs to pull the silicone cover when removing it from the suction cup, which may cause the silicone cover to deform or even damage, causing inconvenience to the operator's operation, so it needs to be improved.

[0048] A limiting groove 21 is provided on the right side of the base 19 , and the interior of the limiting groove 21 is connected to the interior of the base 19 .

[0049] Due to the design of the interior of the limiting groove 21, the object inside will be limited so that it can only move forward and backward.

[0050] Among them, a fixing frame 22 is fixedly installed at the rear of the top of the base 19, a square plate 23 is fixedly installed at the top of the fixing frame 22, a second pneumatic cylinder 24 is fixedly installed at the top of the square plate 23, the bottom end of the second pneumatic cylinder 24 passes through the top of the square plate 23 and extends to below the bottom end of the square plate 23, and an extrusion plate 25 is fixedly installed at the bottom end of the second pneumatic cylinder 24.

[0051] When the second pneumatic cylinder 24 is in operation, the bottom end of the second pneumatic cylinder 24 will drive the extrusion plate 25 to move downward. During this process, the extrusion plate 25 will cooperate with the extrusion mold 20 to extrude and mold the silicone sleeve.

[0053] When the power motor 27 is running, the rotating shaft 28 will rotate.

[0054] The other end of the rotating shaft 28 is fixedly sleeved with a rotating rod 29 , and the other end of the rotating rod 29 is movably sleeved with an extrusion shaft 30 .

[0055] When the rotating shaft 28 rotates, the rotating shaft 28 drives the extrusion shaft 30 to rotate via the rotating rod 29 .

[0056] Among them, the outer surface of the extrusion shaft 30 is movably connected with the vertical block 31, and the second movable block 32 is fixedly installed at the bottom end of the right side of the vertical block 31.

[0057] When the extrusion shaft 30 rotates, its outer surface will squeeze the inside of the vertical block 31, so that the vertical block 31 drives the second movable block 32 to move. Due to the limiting effect of the limiting groove 21, the second movable block 32 will drive the lifting block 15 to move backward as a whole.

[0058] The working principle and use process of this utility model:

[0059] After the dustproof silicone sleeve is extruded and formed, the operator starts the power motor 27. At this time, the rotating shaft 28 will drive the rotating rod 29 to rotate, and then the rotating rod 29 will drive the extrusion shaft 30 to rotate with the rotating shaft 28 as the axis. When the extrusion shaft 30 rotates, its outer surface will squeeze the inside of the vertical block 31 to make the vertical block 31 move, and then the vertical block 31 will drive the second movable block 32 to move. Due to the design inside the limiting groove 21, the movement of the second movable block 32 will be limited so that it can only move forward and backward. At this time, the second movable block 32 will move backward along the inside of the limiting groove 21 driven by the vertical block 31. At this time, the second movable block 32 will drive the pneumatic cylinder bracket 16 to move backward as a whole. When the air When the cylinder bracket 16 moves as a whole to the top of the extrusion die 20, the operator starts the first pneumatic cylinder 17. At this time, the bottom end of the first pneumatic cylinder 17 will drive the lifting block 15 to move downward, and then the lifting block 15 will drive the three suction cups 5 to move downward through the three vertical pipes 3. Due to the design of the appearance of the three suction cups 5, the three suction cups 5 will absorb the dust-proof silicone sleeve located at the top of the extrusion die 20 during the downward movement, thereby realizing the function of automatic absorption of the silicone sleeve. Then the operator starts the first pneumatic cylinder 17 again. At this time, the three suction cups 5 will drive the dust-proof silicone sleeve to move upward. Then the operator starts the power motor 27 again. At this time, the second movable block 32 will drive the lifting block 15 to move forward as a whole.

[0060] When the lifting block 15 moves as a whole to the front of the two fixed frames 22, the operator starts the driving motor 12, and the rotating shaft 13 will rotate, and then the elliptical block 14 will rotate driven by the rotating shaft 13. Since the elliptical block 14 is elliptical in shape, the outer surface of the elliptical block 14 will squeeze and push the front of the square rod 6 during rotation to make the square rod 6 move, and then the square rod 6 will drive the three moving blocks 7 to move at the same time. Since the outer surfaces of the bottom ends of the three moving blocks 7 are respectively connected to the internal activities of the three short rods 2, the three short rods 2 will limit the movement of the three moving blocks 7 so that they can only move forward and backward. At this time, the three moving blocks 7 will be on the square rod 6. The three moving rods 8 will be driven to move backward, and at this time the three moving rods 8 will be driven to move by the three moving blocks 7. At the same time, the other ends of the three moving rods 8 will drive the three hinge blocks 9 to move, and then the three hinge blocks 9 will drive the three round rods 10 to move. Since the three round rods 10 are movably sleeved with the inside of the three vertical tubes 3, the three round rods 10 will move upward along the inside of the three vertical tubes 3. When the bottom ends of the three round rods 10 move upward to above the three pressure relief ports 4, the air will move to the inside of the three vertical tubes 3 through the three pressure relief ports 4, thereby achieving the effect of relieving pressure on the inside of the three vertical tubes 3 and the three suction cups 5, thereby realizing the function of automatically separating the silicone sleeve from the suction cup 5.
