Fig. 1 is a perspective view of a glue removing mechanism 100 in an embodiment, and the glue removing mechanism 100 in this embodiment can be used to separate a double-sided tape 10A from a base paper in a glue paper 10.

Fig. 2(a) is a schematic structural view of the adhesive tape 10 in the peeling mechanism 100, and fig. 2(b) is a cross-sectional view taken along the direction E-E in fig. 2 (a). The adhesive tape 10 includes a double-sided adhesive tape 10A, and a first base paper 10B and a second base paper 10C respectively adhered to the front and back sides of the double-sided adhesive tape 10A. The tape dispensing mechanism 100 in the embodiment shown in fig. 1 is used to separate the second base paper 10C from the double-sided tape 10A, and the first base paper 10B and the double-sided tape 10A are still adhered together.

As shown in fig. 1, the glue dispensing mechanism 100 includes a discharging unit 131, a pressing unit 110, a knife 120, and a drawing unit 132. The discharging unit 131 is wound with the adhesive tape 10 in a roll shape, and one end of the adhesive tape 10 is pulled out of the discharging unit 131, passes through the sheet pressing unit 110 and the poking knife 120, and is finally fixed on the pulling unit 132. As shown in fig. 3, fig. 3 is a schematic diagram of the glue dispensing mechanism 100 during operation. The adhesive tape 10 is pressed against the poking knife 120 by the sheet pressing unit 110, and the second base paper 10C is separated from the double-sided adhesive tape 10A after the adhesive tape 10 passes through the poking knife 120. Specifically, the pick 120 includes a first blade surface 121 and a second blade surface 122, the first blade surface 121 and the second blade surface 122 extend in different directions, a tip 123 is formed at the intersection of the first blade surface 121 and the second blade surface 122, and the second base paper 10C of the adhesive paper 10 is attached to the pick 120. The adhesive tape 10 slides along the first knife face 121, the sheeting unit 110 presses the adhesive tape 10 against the first knife face 121, and the adhesive tape 10 moves against the second knife face 122 after passing through the tip 123. At the tip portion 123, the double-sided tape 10A is detached from the second base paper 10C due to the difference in toughness between the double-sided tape 10A and the second base paper 10C. As shown in fig. 3, the adhesive tape 10 is first moved leftward, the second base paper 10C turns and moves rightward and downward at the tip 123, and the double-sided adhesive tape 10A and the first base paper 10B continue to move in the leftward direction.

In some embodiments, in conjunction with fig. 1, the discharging unit 131 is used for storing the adhesive tape 10, but the storage manner is not limited to the roll manner in the above embodiments. In some embodiments, the pulling unit 132 has an independent power source 132A, the pulling unit 132 fixes the second base paper 10C, and the second base paper 10C is pulled by the independent power source 132A, so that the adhesive tape 10 slides in the adhesive dispensing mechanism 100. The second base paper 10C of the adhesive tape 10 slides against the poking knife 120, and after the adhesive tape 10 passes through the tip 123, the second base paper 10C changes the sliding direction and is separated from the double-sided adhesive tape 10A. The pressing unit 110 ensures that the adhesive tape 10 is attached to the first blade surface 121 of the knife 120, and after passing through the tip 123, the double-sided adhesive tape 10A is separated from the second base paper 10C due to the different toughness of the double-sided adhesive tape 10A and the second base paper 10C. To improve the separation effect, the included angle between the first blade surface 121 and the second blade surface 122 is an acute angle.

In one embodiment, as shown in fig. 1, the power source 132A of the drawing unit 132 is an electric motor, and the drawing unit 132 further includes a rotating clamp 132B, and the rotating clamp 132B clamps the second base paper 10C. The drawing unit 132 further includes a gear transmission mechanism or a belt transmission mechanism for transmitting the power of the power source 132A to the rotating gripper 132B to rotate the rotating gripper 132B, thereby winding the second base sheet 10C on the rotating gripper 132B in a roll shape.

As shown in fig. 1, the glue spreading mechanism 100 further includes a vertical plate 13, and the material feeding unit 131, the knife 120, the pressing unit 110 and the material pulling unit 132 are all disposed on the vertical plate 13. A plurality of guide wheels 14 are further arranged on the vertical plate 13, and the gummed paper 10 is guided by the guide wheels 14. The vertical plate 13 is further provided with a tensioning unit (not shown in the figure), which can adjust the tension of the adhesive paper 10 on the adhesive dispensing mechanism 100, for example, the tensioning unit can be a tensioning wheel fixed on the vertical plate 13 through a spring.

As shown in fig. 3, the gummed paper 10 realizes the separation of the second base paper 10C and the double-sided adhesive tape 10A at the tip 123 of the poking knife 120. In fig. 3, a first base paper 10B is stuck over the double-sided tape 10A. In some embodiments, after the second base paper 10C is separated from the double-sided adhesive tape 10A, it is sucked onto the first base paper 10B by the carrying mechanism 200 and moves together with the first base paper 10B and the double-sided adhesive tape 10A, so that the first base paper 10B and the double-sided adhesive tape 10A are pulled to the next station. In this embodiment, the conveying mechanism 200 is attracted to the first base paper 10B, and the conveying mechanism 200 does not directly contact the double-sided tape 10A, so that the stickiness of the double-sided tape 10A is not reduced. In this embodiment, the carrying mechanism 200 can move synchronously with the first base paper 10B and the double-sided adhesive tape 10A.

In one embodiment, as shown in fig. 1, the glue dispensing mechanism 100 further includes a blowing plate 140 disposed on the vertical plate 13, specifically, the blowing plate 140 is disposed near the tip 123 of the knife 120. The air blowing plate 140 is provided with air holes 141, and when the carrying mechanism 200 is sucked on the first base paper 10B, the air blowing plate 140 blows air upwards through the air holes 141, so that the double-sided adhesive tape 10A and the first base paper 10B move towards the carrying mechanism 200, and the carrying mechanism 200 is ensured to suck the first base paper 10B.

Fig. 4 is a schematic structural diagram of a tape dispenser in one embodiment. As shown in fig. 4, the tape dispenser includes the tape dispensing mechanism 100 in any of the above embodiments; the taping device also includes a handling mechanism 200, a carrier 300, and a tear-off mechanism 400. As shown in fig. 2(a) and 2(B), the adhesive tape 10 moving in the tape applying apparatus includes a first base paper 10B, a double-sided tape 10A, and a second base paper 10C, and the first base paper 10B and the second base paper 10C are respectively adhered to both sides of the double-sided tape 10A. The double-sided adhesive tapes 10A on the second base paper 10C are independently arranged, and the independent arrangement means that a plurality of independent double-sided adhesive tapes 10A are arranged along the extending direction of the second base paper 10C; the first base paper 10B and the double-sided tape 10A correspond to each other one by one, that is, the first base paper 10B is also independent. As shown in fig. 3, after passing through the peeling mechanism 100, the double-sided tape 10A and the first base paper 10B do not need to be cut, thereby facilitating separation. In other embodiments, if the double-sided adhesive tape 10A and the first base paper 10B are continuous, it is only necessary to provide a cutting device to cut the double-sided adhesive tape 10A and the first base paper 10B simultaneously. For example, the cutting device may be a laser cutter, and after the second base paper 10C and the double-sided tape 10A are separated, the first base paper 10B is adsorbed by the conveying mechanism 200, and then the first base paper 10B and the double-sided tape 10A are cut by the laser cutter.

Referring back to fig. 4, the handling mechanism 200 may include a robot 210 and a suction cup driven by the robot 210. Referring to fig. 3, at the position B, the robot 210 may drive the suction cup to suck the first base paper 10B, then the robot 210 drives the suction cup to move left synchronously with the gummed paper 10, the second base paper 10C is separated from the double-sided tape 10A at the position of the tip 123 of the knife 120, the robot 210 may drive the suction cup to suck the first base paper 10B and continue to move left, after moving above the air blowing plate 140, the air blowing plate 140 blows air upwards to ensure that the chassis sucks the first base paper 10B, and after one piece of double-sided tape 10A is separated from the second base paper 10C, the robot 210 drives the suction cup to move the double-sided tape 10A and the first base paper 10B into the carrier 300 together. That is, when the second base paper 10C is not separated from the double-sided tape 10A, or the second base paper 10C is not completely separated from the double-sided tape 10A, the suction cup is sucked on the first base paper 10B, and the robot 210 drives the suction cup to move synchronously with the first base paper 10B. This prevents the double-sided adhesive tape 10A from being pulled or the double-sided adhesive tape 10A from being bent.

As shown in fig. 2(a) and 2(b), the adhesive tape 10 is provided with an identification position 16, and specifically, each of the double-sided tapes 10A is provided with an identification position 16. The identification bits 16 may be a hole structure. As shown in fig. 1, the glue dispensing mechanism 100 includes a position sensing unit 150, and the position sensing unit 150 may be an infrared sensor. The position sensing unit 150 can sense the recognition site 16 so that the position of the adhesive paper 10 can be precisely recognized. In some embodiments, the position sensing unit 150 is in signal connection with the carrying mechanism 200, the position sensing unit 150 generates a sensing signal after sensing the identification position 16, and the carrying mechanism 200 receives the sensing signal, so that the robot 210 of the carrying mechanism 200 can drive the suction cup to accurately move to the set position of the double-sided tape 10A, and further accurately position the double-sided tape 10A, thereby facilitating the robot 210 to accurately attach the double-sided tape 10A to the accurate position of the first workpiece 11 in the subsequent steps. For example, the carrying mechanism 200 adjusts the position of the suction cup on the first base sheet 10B based on the sensing signal. For example, the position sensing unit 150 is disposed upstream of the sheet pressing unit 110, and the adhesive sheet 10 enters the sheet pressing unit 110 after the position sensing unit 150 senses the position of the identification position 16.

As shown in fig. 5, fig. 5 is a partial schematic view of the carrier 300 and the tear mechanism 400 in one embodiment. The carrier 300 has a first workpiece 11 mounted therein, and the first workpiece 11 may be a test card. The robot 210 drives the suction cups to attach the double-sided tape 10A to the first workpiece 11 in the carrier 300. As shown in fig. 4, the tape attaching device further includes a positioning camera 211, and in one embodiment, the robot 210 drives the suction cups to photograph and position the double-sided tape 10A on the positioning camera 211 to further obtain the precise position of the double-sided tape 10A, and then the robot 210 attaches the double-sided tape 10A to the set position of the first workpiece 11 according to the precise position of the double-sided tape 10A.

With continued reference to fig. 5, the carrier 300 and the tearing mechanism 400 are disposed correspondingly, and the tearing mechanism 400 tears off the first base paper 10B attached to the double-sided tape 10A on the first workpiece 11. As shown in fig. 2(a) and 2(B), the first base paper 10B is attached to the double-sided tape 10A, and the first base paper 10B has at least a protruding portion 10B1 protruding from the double-sided tape 10A to the outer periphery, in fig. 2(a), the double-sided tape 10A is shown by a dotted line in the figure, the first base paper 10B covers the double-sided tape 10A, and the periphery of the first base paper 10B protrudes from the double-sided tape 10A to form a protruding portion 10B 1. The projection 10B1 is used for the peeling mechanism 400 to nip and then peel the first base sheet 10B off the double-sided tape 10A.

In one embodiment, as shown in fig. 5, the tearing mechanism 400 comprises a first driving member 410 and a push rod 411 connected to the first driving member 410, and the tearing mechanism 400 further comprises a second driving member 420 and a clamping unit 421 connected to the second driving member 420. The first driver 410 and the second driver 420 may each be a cylinder. The clamping unit 421 may be a gas claw. The first driver 410 can drive the mandril 411 to extend along the directions from J1 to J2 or retract along the directions from J2 to J1; the second driver 420 may drive the grip unit 421 to retract in the J3 to J4 directions, or to extend in the J4 to J3 directions. For example, the first driving member 410 drives the push rod 411 to extend in the direction J1 to J2, so that the push rod 411 pushes out the protruding portion 10B1 of the first base paper 10B toward the clamping unit 421, the clamping unit 421 clamps the protruding portion 10B1 of the first base paper 10B, and the second driving member 420 drives the clamping unit 421 to retract in the direction J3 to J4, so that the first base paper 10B is torn off from the double-sided tape 10A. In the embodiment shown in fig. 5, the directions J1-J2 and J3-J4 are obtuse angles.

Specifically, as shown in fig. 5, the top bar 411 includes a fixing portion 411A and a bending portion 411B. The fixing portion 411A may be a straight rod, and the fixing portion 411A is fixed on the first driving member 410. The bending portion 411B directly contacts with the first base paper 10B, the bending portion 411B is disposed at an obtuse angle with the fixing portion 411A, and the bending portion 411B is bent with respect to the fixing portion 411A. The bent portion 411B is thin. The extending direction of the fixing portion 411A is along the direction of J1 to J2.

As shown in fig. 4, the tape dispenser further includes a feeding mechanism 500, the feeding mechanism 500 carries the second workpiece 12, the second workpiece 12 may be a PCB board, and the carrying mechanism 200 is further configured to take the second workpiece 12 out of the feeding mechanism 500 and move it onto the positioning camera 211 for precise position determination, and then the carrying mechanism 200 applies the second workpiece 12 to the double-sided tape 10A of the first workpiece 11. In some embodiments, since the double-sided tape 10A is already positioned on the tape dispensing mechanism 100 by the position sensing unit 150, the double-sided tape 10A may not need to be positioned by the positioning camera 211, and the positioning camera 211 only positions the second workpiece 12. In operation, after the conveying mechanism 200 conveys the double-sided tape 10A and the first base paper 10B from the tape dispensing mechanism 100 to the carrier 300, the conveying mechanism 200 immediately moves to the feeding mechanism 500 to take the second workpiece 12 out, and then moves to the positioning camera 211 to precisely position the second workpiece 12. That is, the process of moving the carrying mechanism 200 to the loading mechanism 500 to pick up the second workpiece 12 and the step of tearing the first base paper 10B from the double-sided tape 10A by the tearing mechanism 400 can be performed simultaneously. After the tearing mechanism 400 tears the first base paper 10B from the double-sided tape 10A, the carrying mechanism 200 attaches the positioned second workpiece 12 to the double-sided tape 10A of the first workpiece 11.

As shown in fig. 4, the adhesive applying apparatus further includes a conveying member 310, and the conveying member 310 is used for conveying the carrier 300. For example, the conveying member 310 may be a linear conveying line, and the carriers 300 are moved to different stations by the driving of the conveying member 310. For example, the transport member 310 transports a plurality of carriers 300, and the carriers 300 are provided with the first workpieces 11. When the carrier 300 carries the first workpiece 11 and moves to the tearing mechanism 400, the carrying mechanism 200 attaches the double-sided tape 10A with the first base paper 10B to the first workpiece 11, and then the tearing mechanism 400 tears the first base paper 10B from the first workpiece 11. The transport member 310 then drives the carrier member 300 to move to the next station where the carrying mechanism 200 attaches the second workpiece 15 to the double-sided tape 10A of the first workpiece 11.
