Description

Technical Field

[0001] This invention relates to a mechanism for tearing release paper from adhesive tape on cardboard, belonging to the technical field of carton manufacturing equipment. Background Technology

[0002] In the manufacturing process of many electronic products, packaging is involved, such as mobile phones and tablets. After the finished products are manufactured, they need to be packaged according to category, with similar products placed in the same cardboard box. The raw material for the cardboard boxes is usually cardboard. The cardboard is folded to form the box. Double-sided tape is usually pre-applied to the cardboard. Before folding, the release liner on the double-sided tape must be peeled off to expose the adhesive layer. Then, when the cardboard is folded, the adhesive layer holds the folded cardboard pieces together, ultimately forming the box. Manual operation is inefficient and prone to errors; therefore, a mechanical mechanism is needed to automatically remove the release liner from the cardboard. Furthermore, cardboard typically has multiple double-sided tape areas, and these areas often have creases. These creases protrude from the cardboard surface due to height differences between the creases and the rest of the cardboard. When using a conventional tape-removing mechanism, the creases can obstruct the peeling blade, preventing the grippers from tearing the tape and causing the mechanism to fail.

[0003] Patent application publication number CN 109263243 A discloses a release paper tearing device, including a mounting bracket, a horizontal drive mechanism, a main lifting drive mechanism, a clamping component mounting frame, a suction cup drive mechanism, a suction cup, an upper clamping member, a lower clamping member drive mechanism, and a lower clamping member; the main lifting drive mechanism is connected to the output end of the horizontal drive mechanism; the clamping component mounting frame is connected to the output end of the main lifting drive mechanism; the suction cup drive mechanism, the upper clamping member, and the lower clamping member drive mechanism are mounted on the clamping component mounting frame; the suction cup is configured to move downward under the drive of the suction cup drive mechanism to suck up the edge of the release paper or move upward to pull up the release paper; the lower clamping member can move to directly below the upper clamping member and move upward toward the upper clamping member or downward away from the upper clamping member and move out from directly below the upper clamping member; the horizontal drive mechanism can drive the suction cup and the upper clamping member to move directly above the edge of the release paper or drive the edge of the release paper to move in the corresponding direction to completely tear the release paper. However, this invention relies on a suction cup to pick up the release paper and then tear it off. For double-sided tape with strong adhesion, the suction cup may not be able to pick up the release paper, thus failing to complete the tearing action. It is also insufficient for removing release paper from double-sided tape on creased cardboard. Summary of the Invention

[0004] The main technical problem solved by this invention is to provide a mechanism for tearing release paper off adhesive tape on cardboard. This mechanism is used to tear off the release paper on the surface of double-sided adhesive tape attached to cardboard, replacing manual operation, with high work efficiency and less risk of damage to the cardboard.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A mechanism for tearing release paper from cardboard includes a cardboard placement rack for placing cardboard, a cardboard adsorption mechanism on the cardboard placement rack, a horizontal transverse slide module below the cardboard placement rack, a horizontal longitudinal slide module slidably disposed on the horizontal transverse slide module, and a release paper tearing mechanism slidably disposed on the horizontal longitudinal slide module. The release paper tearing mechanism includes a vertical moving module, which includes a gripper for clamping the release paper from the cardboard, a positioning block, and a pointed needle that can move horizontally and linearly. The outer end of the pointed needle is a pointed head, and the pointed head points towards the release paper from the cardboard.

[0006] Preferably, the vertical movement module includes a first vertical slide rail and a first lifting cylinder. A first slider is provided on the first vertical slide rail, and the first lifting cylinder drives the first slider to move vertically on the first vertical slide rail. A vision inspection mechanism and a fixed seat are provided on the first slider. A second vertical slide rail is provided on the fixed seat. A first horizontal slide rail is slidably provided on the second vertical slide rail. A second lifting cylinder is provided on the fixed seat for driving the first horizontal slide rail to slide and lift on the second vertical slide rail. A second slider and a first horizontal linear drive cylinder for driving the second slider to slide on the first horizontal slide rail are slidably provided on the first horizontal slide rail. A pointed pin mounting seat is provided on the second slider, and the pointed pin is mounted on the pointed pin mounting seat. The positioning block is located at the top of the fixed seat and below the gripper. A third lifting cylinder for driving the gripper to lift is provided on the fixed seat.

[0007] Preferably, the first slider is provided with a rotary drive cylinder for driving the fixed seat and the second vertical slide rail on the fixed seat to rotate as a whole.

[0008] Preferably, the cardboard adsorption mechanism is equipped with a photoelectric sensor for detecting the presence or absence of cardboard.

[0009] Preferably, the visual inspection mechanism includes a CCD camera.

[0010] Preferably, the gripper and positioning block are located beside the pointed needle.

[0011] Preferably, the tip of the needle is coated with a Teflon coating.

[0012] Preferably, it further includes a control unit for controlling the operation of the horizontal transverse slide module, the horizontal longitudinal slide module, the vertical movement module, the first lifting cylinder, the vision inspection mechanism, the first horizontal linear drive cylinder, the second lifting cylinder, the third lifting cylinder, and the rotary drive cylinder, wherein the horizontal transverse slide module, the horizontal longitudinal slide module, the vertical movement module, the first lifting cylinder, the vision inspection mechanism, the first horizontal linear drive cylinder, the second lifting cylinder, the third lifting cylinder, and the rotary drive cylinder are respectively signal-connected to the control unit.

[0013] The beneficial effects of this invention are as follows: The release paper tearing mechanism for double-sided adhesive tape on cardboard is used to tear off the release paper from the surface of the double-sided adhesive tape on the cardboard. By setting a three-dimensionally movable release paper tearing mechanism, the release paper on the surface of the double-sided adhesive tape is peeled off, then the peeled release paper is clamped, and finally the release paper is torn off from the double-sided adhesive layer. This replaces manual operation and has high work efficiency. The pointed needle first inserts between the double-sided adhesive tape and the cardboard to lift the release paper on the surface of the double-sided adhesive tape, and then the gripper clamps and tears the release paper off. It has a good effect on tearing the release paper of double-sided adhesive tape with strong adhesion. Moreover, by setting a rotary drive cylinder, the entire pointed needle and gripper can be moved. The mechanism rotates 180°, causing the pointed needles and grippers to move from the outside of the crease to the inside when tearing the release paper from different creases. This prevents the pointed needles and grippers from being blocked by the creases, making the cardboard less likely to break. This allows the release paper on the double-sided adhesive to be easily torn off at the creases. In addition, the outer tip of the pointed needle is coated with a Teflon coating with anti-stick properties, making it less likely for the tip to stick to the double-sided adhesive during long-term operation. This allows it to work normally for a long time. Ordinary pointed needles or grippers are prone to sticking to the double-sided adhesive during long-term operation, and they will not work properly when more and more adhesive sticks to them.

[0017] Preferably, the vertical movement module 7 includes a first vertical slide rail 11 and a first lifting cylinder 12. A first slider 13 is provided on the first vertical slide rail 11. The first lifting cylinder 12 drives the first slider 13 to move vertically on the first vertical slide rail 11. A vision inspection mechanism 14 and a fixed base 15 are provided on the first slider 13. A second vertical slide rail 16 is provided on the fixed base 15. A first horizontal slide rail 17 is slidably provided on the second vertical slide rail 16. A second lifting cylinder 18 is provided on the fixed base 15 for driving the first horizontal slide rail 17 to slide and lift on the second vertical slide rail 16.

A pointed pin mounting seat 21 is provided on the second slider 19, and one end of the pointed pin 10 is mounted on the pointed pin mounting seat 21. The first horizontal linear drive cylinder 20 drives the second slider 19 and the pointed pin 10 to move horizontally. When the first horizontal transverse slide rail 17 slides and rises and falls on the second vertical slide rail 16, the second slider 19 and the pointed pin 10 rise and fall accordingly. The positioning block 9 is located at the top of the fixed seat 15 and below the gripper 8. A third lifting cylinder 22 for driving the gripper 8 to rise and fall is provided on the fixed seat 15.

[0018] Preferably, the first slider 13 is provided with a rotary drive cylinder 23 for driving the fixed base 15 and the second vertical slide rail 16 on the fixed base 15 to rotate as a whole.

[0019] Preferably, the cardboard adsorption mechanism 3 is equipped with a photoelectric sensor 24 for detecting the presence or absence of cardboard.

[0020] Preferably, the visual inspection mechanism 14 includes a CCD camera 25.

[0021] Preferably, the tip 101 of the pointed needle 10 is coated with a Teflon coating, which has anti-stick properties, so that the tip is not easily sticked with the adhesive on the double-sided tape during long-term operation, thus enabling it to work normally for a long time.

[0022] Preferably, the system further includes a control unit 26 for controlling the operation of the horizontal transverse slide module 4, the horizontal longitudinal slide module 5, the vertical movement module 7, the first lifting cylinder 12, the vision inspection mechanism 14, the first horizontal linear drive cylinder 20, the second lifting cylinder 18, the third lifting cylinder 22, and the rotary drive cylinder 23. The horizontal transverse slide module 4, the horizontal longitudinal slide module 5, the vertical movement module 7, the first lifting cylinder 12, the vision inspection mechanism 14, the first horizontal linear drive cylinder 20, the second lifting cylinder 18, the third lifting cylinder 22, and the rotary drive cylinder 23 are respectively connected to the control unit 26 via signal communication.

[0023] When the paperboard release liner mechanism of the present invention is used, the paperboard 2 with double-sided adhesive tape is placed on the paperboard placement rack 1. The paperboard adsorption mechanism 3 adsorbs the paperboard 2 and attaches it to the paperboard placement rack 1. The double-sided adhesive tape on the paperboard is at the bottom of the paperboard 2. The photoelectric sensor 24 detects the presence of the paperboard 2 on the paperboard placement rack 1. The CCD camera 25 of the vision detection mechanism 14 illuminates the position of the double-sided adhesive tape on the paperboard 2 and transmits the position information to the control unit 26. The control unit 26 controls the horizontal longitudinal slide module 5 to slide laterally on the horizontal transverse slide module 4, and the tape release liner execution mechanism 6 to slide longitudinally on the horizontal longitudinal slide module 5. The first lifting cylinder 12 of the vertical movement module 7 drives the first slider 13 to move vertically on the first vertical slide rail 11. The pointed needle 10, the gripper 8, and the positioning block 9 are moved to the working position of the tape release liner. The pointed needle 10 is lifted. The height is equal to the height of the double-sided tape on the cardboard crease. The first horizontal linear drive cylinder 20 drives the second slider 19 and the pointed needle 10 to move horizontally laterally. The pointed head 101 of the pointed needle 10 moves linearly from the outside to the inside of the cardboard crease. The pointed head 101 is inserted between the release paper and the adhesive layer of the double-sided tape at the cardboard crease and lifts the release paper. Generally, two pointed needles are inserted side by side at the same time between the release paper and the adhesive layer of the double-sided tape. The third lifting cylinder 22 drives the gripper 8 to descend and clamp the lifted release paper between the gripper 8 and the positioning block 9. Then, the tape release paper tearing actuator 6 slides horizontally longitudinally on the horizontal longitudinal slide module 5 to tear the release paper off the double-sided tape. Alternatively, according to the adhesive direction of the double-sided tape, the tape release paper tearing actuator 6 slides horizontally laterally through the horizontal transverse slide module 4 to tear the release paper off the double-sided tape.

[0024] If it is necessary to remove the release paper from the double-sided adhesive at the crease on the other side of the cardboard 2, the rotary drive cylinder 23 drives the fixed base 15 and the second vertical slide rail 16 on the fixed base 15 to rotate 180° as a whole. The pointed needle 10, the gripper 8, the positioning block 9, etc., also rotate 180°, so that the pointed head 101 of the pointed needle 10 still moves in a straight line from the outside of the corresponding cardboard crease, that is, from the higher side of the crease to the lower side. The pointed head 101 inserts between the release paper and the adhesive layer of the double-sided adhesive at the cardboard crease, lifts the release paper, and the gripper 8 tears off the release paper. This avoids the pointed head 101 from inserting into the cardboard crease and damaging the cardboard, and also avoids failure to tear the release paper, thus successfully removing the release paper from the double-sided adhesive at the crease. The cardboard release paper tearing mechanism of the present invention replaces the manual operation of tearing the release paper of double-sided adhesive tape, which has high working efficiency, can work normally for a long time, and the cardboard is not easily damaged.
