Description

Technical Field

[0001] The invention relates to the field of automated machinery, and in particular to a material stripping device capable of improving a stripping success rate. Background Art

[0002] Nowadays, when materials used for pasting are transported as raw materials, they need to be pasted on material tapes for transportation. After the manufacturer receives the material tape with the material attached, the material needs to be peeled off the material tape and then pasted on the product. In the semiconductor industry, Mylar materials are mainly transported and used in the above-mentioned manner, and are widely used in electrical insulation, PCB board insulation, protection, etc. However, since Mylar materials are flexible materials and the Mylar materials used in the semiconductor industry are relatively small, the existing equipment for stripping materials mainly sets a bend on the equipment, and pulls the material strip with the material attached to it close to the bend through a traction device to strip the material into a receiving tray. Therefore, such equipment is prone to stripping failure when stripping the above-mentioned Mylar materials, affecting the stripping efficiency. In order to be able to strip flexible and relatively small materials, a suction nozzle or other mechanism is generally used to adsorb and fix the material on the tape, and then the tape is pulled by the above-mentioned equipment for stripping. However, since the suction nozzle is generally fixed and cannot move with the tape, the part of the tape with the attached material cannot enter the bend for stripping, and it can only be forcibly stripped by the suction force of the suction nozzle and the pulling force of pulling the tape. However, the stripping effect of this method is worrying, and wrinkles are easily formed on the material.

[0024] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, further description is given below in conjunction with the implementation modes and the accompanying drawings.

[0025] See also Figures 1 to 5 The present invention discloses a material stripping device capable of improving the success rate of stripping, comprising a frame 1 and a feeding device 2, a belt pressing device 3, a stripping device 4, a first driving mechanism 42 and a pulling device 5 installed on the frame 1; the feeding device 2 is used to place a material belt attached with a material; the material belt pulled out by the feeding device 2 passes through the belt pressing device 3, the stripping device 4 and the pulling device 5 in sequence; the belt pressing device 3 is used to press or loosen the material belt; the pulling device 5 is used to pull the material belt; the stripping device 4 comprises a stripping table 41 and a winding shaft 411 located below the stripping table 41, and the material The belt extends along the stripping table 41 and is bent at the end 412 of the stripping table 41 and is clamped on the pulling device 5 after passing downward around the winding shaft 411. The portion of the belt between the pulling device 5 and the winding shaft 411 is parallel to the portion of the belt on the stripping table 41. The first driving mechanism 42 is used to drive the stripping device 4 to move in a direction opposite to the pulling direction toward the pulling device 5 when the belt pressing device 3 presses the belt and the pulling device 5 clamps the belt, so that the belt on the stripping table 41 is bent through the end 412 of the stripping table 41 to strip the material attached to the belt.

[0026] The present invention can allow the material belt pulled out from the feeding device 2 to pass through the belt pressing device 3, the stripping device 4 and the pulling device 5, and the stripping device 4 includes a stripping table 41 and a winding shaft 411 located below the stripping table 41, and the material belt can be bent through the end 412 of the stripping table 41 and downwardly pass around the winding shaft 411 to be clamped on the pulling device 5, when the material stripping operation is performed, the material picking device 6 can fix the material on the material belt, the belt pressing device and the pulling device 5 respectively press and clamp the material belt, and the first driving mechanism 42 drives the stripping device 4 to move in a direction opposite to the pulling direction of the pulling device 5, so that the material belt on the stripping table 41 passes through the end 412 of the stripping table 41 to form a bend to strip the material fixed by the material picking device 6 on the material belt, wherein the material belt portion between the pulling device 5 and the winding shaft 411 is parallel to the material belt portion located on the stripping table 41, so as to ensure that the material belt remains taut during the reverse movement of the stripping device 4 in the opposite direction to the pulling direction of the pulling device 5. The present invention can peel off the material when the material on the material belt is fixed by the material picking device 6, which is suitable for small and soft materials and is beneficial to improving the success rate of material peeling. Moreover, after the material peeling is completed, the material fixed by the material picking device 6 can be taken away by the material picking device 6 while maintaining the posture when it is attached to the material belt, thus avoiding the situation where the material posture is inconsistent due to the need for the material picking device 6 to take the material from the receiving tray.

[0027] See also Figure 1 Specifically, the feeding device 2 includes a winding shaft 21 for winding the material tape, and the winding shaft 21 is connected to the frame 1. When the pulling device 5 pulls the material tape, the winding shaft 21 can rotate to release the material tape wound on the winding shaft 21. Placing the material tape by winding is conducive to keeping the pulled material tape in a taut state.

[0028] Furthermore, the axis 411 is rotatably disposed on the stripping table 41 . When the stripping table 41 moves in a direction opposite to the pulling direction of the pulling device 5 to strip the material, the rotation of the axis 411 is beneficial to reducing resistance.

[0029] It can be understood that by making the portion of the material tape between the pulling device 5 and the winding shaft 411 parallel to the portion of the material tape on the stripping table 41, when the stripping table 41 moves away from the pulling device 5, the reduced length of the material tape on the stripping table 41 is consistent with the increased length of the material tape between the pulling device 5 and the winding shaft 411, thereby ensuring that the material tape remains taut.

[0030] See also Figures 1 to 4 In some embodiments, after the stripping device 4 moves in a direction opposite to the pulling direction of the pulling device 5 to strip the material on the material belt, the first driving mechanism 42 drives the stripping device 4 to move in a direction same as the pulling direction of the pulling device 5 to move the stripping table 41 to the stripping position, the belt pressing device 3 releases the material belt and the pulling device 5 pulls the material belt for a preset length before the belt pressing device 3 presses the material belt again; the end 412 of the stripping table 41 is provided with a bending portion 413 for bending the material belt, and in the process of the stripping table 41 moving to the stripping position, the front end of the material belt portion with the material attached is pulled to the bending portion 413 to pre-strip the material and then returns to the stripping device 4 under the action of the movement of the stripping device 4, that is, it is located on the stripping table 41. In this embodiment, only one piece of material is peeled off each time. After each piece of material is peeled off, the peeling table 41 needs to be moved back to the peeling position, and the pulling device 5 also needs to pull the material strip to move a preset length, so that the part of the material strip with the material attached is located on the peeling table 41 and corresponds to the material picking device 6. During the movement, the front end of the part of the material strip with the material attached is moved to the bending portion 413, so that the material on this part of the material strip can be pre-peeled, thereby improving the success rate of the subsequent formal peeling.

[0031] It can be understood that the front end of the material strip portion with material attached refers to the material strip portion with material attached that is in the same direction as the pulling direction of the pulling device 5 and is closest to the bending portion 413, that is, the material strip portion where the material to be peeled off is located.

[0032] Specifically, in the process of the stripping table 41 moving to the stripping position, the moving speed of the stripping table 41 may be lower than the speed at which the pulling device 5 pulls the material strip, or the pulling device 5 pulls the material strip before the stripping table 41 moves, or the stripping table 41 moves first and the speed at which the pulling device 5 pulls the material strip is higher than the speed at which the stripping table moves, so that the portion of the material strip with the material attached and located on the stripping table 41 close to the bending portion 413 moves to the bending portion 413.

[0033] It can be understood that the stripping position refers to the position of the stripping table 41 corresponding to when the material taking device 6 fixes the material on the material belt, that is, the initial position of the stripping device 4 when performing the stripping operation.

[0034] See also Figure 4 Specifically, the end 412 of the stripping table 41 includes an upper surface 4121 and an inclined surface 4122, the upper surface 4121 and the inclined surface 4122 are connected to form an acute angle, and the material strip passes through the upper surface 4121 and is bent at the acute angle away from the pulling device 5. By bending the material strip at the acute angle away from the pulling device 5, the success rate of material stripping is improved.

[0035] See also Figure 1 , Figure 3 and Figure 7 In some embodiments, the belt pressing device 3 includes a pressure contact member 31 and a pressure member 32. The pressure contact member 31 can be movably arranged on the frame 1 up and down, and the pressure member 32 is used to apply pressure to the pressure contact member 31 so that the pressure contact member 31 presses the material belt passing through the pressure contact member 31.

[0036] Specifically, the pressure member 32 is an electromagnet, and the pressure member 32 is arranged below the pressure contact member 31. The part of the pressure contact member 31 facing the pressure member 32 is a magnetic metal. The pressure contact member 31 abuts against the material strip under the action of gravity. The pressure member 32 can be energized to generate magnetic force to attract the pressure contact member 31 so that the pressure contact member 31 obtains downward pressure to compress the material strip. When the pressure member 32 does not apply pressure to the pressure contact member 31, the pressure contact member 31 still abuts against the material strip under the action of gravity, and the pulling device 5 can flatten the material strip passing through the pressure contact member 31 when pulling the material strip.

[0037] See also Figure 3 and Figure 7 Furthermore, the pressure contact piece 31 abuts against the portion of the material strip to which the material is not attached to avoid pressing the material and causing deformation of the material; the pressure contact piece 31 is connected to the frame 1 through a sliding structure 33, and the sliding structure 33 includes a sliding column 332 and a linear bearing 331 sleeved on the sliding column 332. The sliding column 332 can slide up and down along the linear bearing 331. The sliding column 332 is connected to the pressure contact piece 31. When the pulling device 5 pulls the material strip, the sliding column 332 can slide upward to lift the pressure contact piece 31.

The stripping device 4 can be laterally movably arranged on the transverse moving guide rail 423. The transmission mechanism 422 is connected to the stripping device 4. The first driver 421 drives the stripping device 4 to move along the transverse moving guide rail 423 through the transmission mechanism 422 to approach or move away from the pulling device 5.

[0039] It can be understood that the stripping device 4 is disposed on the transverse moving guide rail 423 so as to be laterally movable, and the stripping device 4 may be connected to a slider, and the stripping device 4 may be disposed on the transverse moving guide rail 423 so as to be laterally movable through the cooperation of the slider and the transverse moving guide rail 423; or the stripping device 4 is connected to a guide rail that cooperates with the transverse moving guide rail 423, and the two cooperate to form a cooperation structure of a cross roller guide rail, so that the stripping device 4 may be disposed on the transverse moving guide rail 423 so as to be laterally movable. The transmission mechanism 422 is a screw mechanism, and the screw mechanism includes a screw shaft 4221 and a screw nut 4222 sleeved on the screw shaft 4221, the screw shaft 4221 is connected to the output end of the first driver 421, the screw nut 4222 is connected to the stripping device 4, and the first driver 421 drives the screw shaft 4221 to rotate so as to move the screw nut 4222 on the screw shaft 4221 to drive the stripping device 4 to move laterally.

[0040] See also Figures 3 to 6 In some embodiments, the pulling device 5 includes a second driving mechanism 52 and a pulling roller group 51. The pulling roller group 51 forms a conveying channel 53 through which the feeding belt passes. The second driving mechanism 52 is connected to the pulling roller group 51. The pulling roller group 51 can clamp the belt located in the conveying channel 53 and pull the belt when the second driving mechanism 52 drives the pulling roller group 51 to rotate.

[0041] Specifically, the pulling roller group 51 includes a first transmission roller 511 and a second transmission roller 512. The first transmission roller 511 is connected to the second driving mechanism 52. The second transmission roller 512 can be close to or away from the first transmission roller 511. The second transmission roller 512 close to the first transmission roller 511 can form a conveying channel 53 and clamp the material belt located in the conveying channel 53. The second driving mechanism 52 drives the first transmission roller 511 to rotate so that the second transmission roller 512 close to the first transmission roller 511 rotates to pull the material belt.

[0042] It can be understood that the second driving mechanism 52 includes a second driver 521, a worm gear transmission mechanism 522, a first gear 523 and a second gear 525, wherein the worm gear transmission mechanism 522 includes a worm 5222 and a worm wheel 5221, the worm wheel 5221 and the first gear 523 are coaxially connected via a rotating shaft 524, the first gear 523 is meshed with the second gear 525, the second gear 525 is coaxially connected with the first transmission roller 511, and the second driver 521 can drive the worm 5222 to rotate to drive the turbine 5221, the first gear 523, the second gear 525 and the first transmission roller 511 to rotate.

[0043] See also Figure 4 and Figure 6Furthermore, the device further includes an eccentric connection mechanism 8, which includes a bearing 81, a connecting shaft 83 and a rotating member 82. The bearing 81 is rotatably arranged on the frame 1. The bearing 81 is eccentrically connected to the side of the first transmission roller 511 through the connecting shaft 83. The rotating member 82 is connected to the connecting shaft 83. The rotating member 82 can drive the first transmission roller 511 to approach or move away from the second transmission roller 512 through the connecting shaft 83. By eccentrically connecting the bearing 81 to the first transmission roller 511, the rotating member 82 can change the rotation radius of the first transmission roller 511, thereby making the first transmission roller 511 approach or move away from the second transmission roller 512. When the first transmission roller 511 moves away from the second transmission roller 512, the material strip can be manually pulled between the first transmission roller 511 and the second transmission roller 512.

[0044] See also Figure 2 and Figure 5 In some embodiments, a photoelectric sensor 7 is provided on the frame 1, and the photoelectric sensor 7 senses the position of the material-retrieving device 6 for fixing and taking away the material. The photoelectric sensor 7 is provided above the stripping device 4 and is aligned with the direction of the material belt pulling. When the material-retrieving device 6 fixes the material, the photoelectric sensor 7 can sense the material-retrieving device 6, and then enter the stripping operation; after the material-retrieving device 6 takes away the material, the photoelectric sensor 7 can sense the movement of the material-retrieving device 6, and then drive the movement of the stripping device 4 and the pulling device 5 to pull the material belt, so that the stripping device 4 and the material belt return to the stripping position.

[0045] It can be understood that the material taking device 6 can be a suction nozzle mechanism, which can fix the material on the material belt through suction and suck and take away the material.

[0046] The above disclosure is only the preferred embodiment of the present invention, which cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope of the present invention.
