Description

Fully automatic tape dispenser Technical Field

[0001] The utility model belongs to the technical field of lens tape sticking equipment, in particular to a full-automatic tape sticking machine. Background Art

[0002] In the lens production line, the tape machine is used to bond the A mold and B mold of the lens with tape, forming a cavity for pouring the lens molding liquid between the A mold and the B mold of the lens.

[0003] Chinese patent publication CN107972214A discloses a multifunctional fully automatic tape machine comprising a left-side molding mechanism and a right-side molding mechanism, with a fixed film feed mechanism disposed between the two molding mechanisms and a movable positioning mechanism disposed at the rear of the film feed mechanism. The positioning mechanism is mounted on a guide rail and connected to a screw. The screw is rotated to move the positioning mechanism to the left or right molding mechanism according to a program for molding. In this application, the film feed mechanism 2 delivers the A and B molds to the positioning mechanism 3. Specifically, the A mold conveyor belt 21 delivers the A mold to the end of the positioning cylinder for positioning. The A mold suction cylinder drives the A mold suction cup to descend and absorb the A mold. The A mold feed cylinder 24 operates to deliver the A mold to the A mold positioning arm 16. The B mold conveyor belt 22 delivers the B mold to the end of the positioning cylinder for positioning. The B mold loading cylinder 25 below the end loads the B mold in two stages, positioning the B mold within the B mold positioning arm.

[0004] The shortcomings of the above technical solution are: mold A and mold B are positioned separately by the mold A center positioning cylinder and the mold B center positioning cylinder, and the distance between the mold A positioning arm and the mold B positioning arm is large, resulting in a large stroke of the suction wheel when taking the film.

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] As shown in Figure 1-5, the fully automatic tape machine includes: A-mold conveyor belt 8, B-mold conveyor belt 9, die-outlet conveyor belt 10, die positioning mechanism, upper spindle 11, lower spindle 12, die pressing mechanism and tape wrapping mechanism.

[0028] The B-mold conveyor belt 9 is positioned below the A-mold conveyor belt 8. A mold pre-positioning mechanism is provided at the rear end of the A-mold conveyor belt 8, and a mold pre-positioning mechanism is provided at the rear end of the B-mold conveyor belt 9. Both the A-mold and B-mold pre-positioning mechanisms comprise two pre-positioning jaws 13 and a pre-positioning cylinder 14. The pre-positioning cylinder 14 connects the two pre-positioning jaws 13 to drive them to clamp and open. The two pre-positioning jaws 13 are provided with isosceles trapezoidal pre-positioning slots facing each other.

[0029] The die positioning mechanism includes an A-die moving mechanism, a positioning module, a B-die lifting mechanism, and a screw translation mechanism 15 .

[0030] The A-mold moving mechanism is located at the rear end of the A-mold conveyor belt 8. It includes an A-mold translation cylinder, an A-mold lifting cylinder 17, and an A-mold suction cup 18. The A-mold lifting cylinder 17 is connected to the A-mold suction cup to drive the A-mold suction cup 18 up and down, while the A-mold translation cylinder is connected to the A-mold lifting cylinder 17 to drive the A-mold lifting cylinder to translate.

[0031] The positioning module includes two A-mold positioning clamping arms 19, four A-mold positioning claws 20, an A-mold clamping arm cylinder 21, two B-mold positioning clamping arms 22, four B-mold positioning posts 38, and a B-mold clamping arm cylinder 39. The two A-mold positioning clamping arms 19 are located at the upper end of the positioning module, while the two B-mold positioning clamping arms 22 are located at the lower end. The A-mold clamping arm cylinder 21 drives the two A-mold positioning clamping arms 19 to open and clamp, while the B-mold clamping arm cylinder 39 drives the two B-mold positioning clamping arms 22 to open and clamp. Each A-mold positioning clamping arm 19 is equipped with two A-mold positioning claws 20, and each B-mold positioning clamping arm 22 is equipped with two B-mold positioning posts 39. When the A mold positioning clamping arms 19 are tightened, the four A mold positioning claws 20 on the two A mold positioning clamping arms 19 clamp the A mold to position it. When the B mold positioning clamping arms 22 are tightened, the four B mold positioning posts 38 on the two B mold positioning clamping arms 22 clamp the B mold to position it. The screw translation mechanism 15 is connected to the positioning module to drive the positioning module to translate toward the upper spindle 11 and the lower spindle 12.

[0032] Several sets of sliding friction plates 23 are provided between the two A-mold positioning arms 19 and the two B-mold positioning arms 22. Each set of sliding friction plates includes an A-mold arm sliding friction plate and a B-mold arm sliding friction plate. The A-mold arm sliding friction plate is fixedly mounted on the A-mold positioning arms 19, while the B-mold arm sliding friction plate is fixedly mounted on the B-mold positioning arms 22. The A-mold arm sliding friction plate and the B-mold arm sliding friction plate are slidably connected. The A-mold arm sliding friction plate is embedded in the A-mold positioning arms 19 and slightly protrudes from the A-mold positioning arms 19. The B-mold arm sliding friction plate is embedded in the B-mold positioning arms 22 and slightly protrudes from the B-mold positioning arms 22. The sliding friction plates 23 reduce friction during movement of the A-mold positioning arms 19 and the B-mold positioning arms 22, thereby increasing the service life of the A-mold positioning arms 19 and the B-mold positioning arms 22.

[0033] The B-mold lifting mechanism includes a lifting seat 1, a correction head 2, a double-stroke cylinder 3, a lifting seat base 4, a guide rod 5, a mounting frame 6, and a spring 7.

[0034] The upper end and the lower end of the two-stroke cylinder 2 are slidably connected to the mounting bracket 6 along the up-down direction. The guide rod 6 is fixedly connected to the upper end of the two-stroke cylinder 3.

[0035] The top of the mounting frame 6 is fixedly mounted with the lifting seat base 4. The guide rod 5 is sleeved in the lifting seat base 4. The guide rod 5 is rotatably connected to the lifting seat base 4 through a set of bearings, and the guide rod 5 can rotate and rise and fall relative to the lifting seat base 4.

[0036] The spring 7 is sleeved on the guide rod 5 and is located between the lifting seat base 4 and the lifting seat 1 .

[0037] The deflection correcting head 2 is rotatably connected to the top of the guide rod 5. The top of the deflection correcting head 2 is spherical.

[0038] The lifting seat 1 is mounted on the top of the guide rod 5 and is tension-fitted with the guide rod 5. The lifting seat 1 can be raised and lowered along the guide rod 5. After the lifting seat 1 is lowered relative to the guide rod 5, the top of the deflection correction head 2 can be exposed relative to the upper surface of the lifting seat 1.

[0039] A limiting step is provided at the lower inner portion of the lifting seat 1. When the limiting step abuts against the bottom of the correcting head 2, the lifting seat 1 is limited by the correcting head 2 to prevent the lifting seat 1 from continuing to move upward along the guide rod 5 and then detaching from the guide rod 5.

[0040] The working process of the B-mold lifting mechanism is as follows:

[0041] 1. The two-stroke cylinder 3 drives the guide rod 5 to lift upward until the lifting seat 1 lifts the B mold to the B mold positioning seat for positioning. This is the first stroke of the two-stroke cylinder 3;

[0042] 2. The two-stroke cylinder 3 drives the guide rod 5 to continue to lift upward until the lifting seat 1 places the B mold on the step of the B mold positioning seat. Then the spring 7 is compressed and the top of the correcting head 2 extends out of the lifting seat 1. This is the second stroke of the two-stroke cylinder 3.

[0043] At this time, the top of the correction head 2 contacts the center of the depression on the lower surface of the B mold, correcting the position of the B mold so that the outer peripheral surface of the B mold contacts the four B mold positioning pillars 38 at the same time;

[0044] 3. After the B mold is positioned, the double-stroke cylinder 3 drives the guide rod 5 to descend. Under the action of the spring 7, the lifting seat 1 is reset and the correction head 2 is retracted into the lifting seat 1.

[0045] The upper spindle 11 and the lower spindle 12 are both driven to rise and fall by a servo motor. Suction wheels 24 are provided at opposite ends of the upper spindle 11 and the lower spindle 12. The upper spindle 11 and the lower spindle 12 are both driven to rotate by a stepping motor.

[0046] The die-tightening mechanism includes two die-tightening rollers 35 and a die-tightening cylinder 36. Two die-tightening rollers 35 are provided, each rotatably connected to a roller mounting frame 37. The die-tightening cylinder 36 is connected to the roller mounting frame 37 to drive the mounting frame 37 toward and away from the die on the suction wheel 24. The central axis of the die-tightening rollers 35 is parallel to the central axis of the die. During tightening, the die-tightening rollers 35 are in close contact with the outer circumference of the die and rotate with the die.

[0047] The tape wrapping mechanism includes a tape feeding plate 27 driven by a tape feeding cylinder 26, and a tape feeding plate 27 is provided with a tape swing arm 28 and a tape mounting wheel 34. The front end of the tape swing arm 28 is provided with a tape wheel 29, and the tape swing arm 29 is driven by the tape cylinder 30.

[0048] The tape wrapping mechanism also includes a tape-lifting cylinder 31 and a tape-lifting roller 32. The tape-lifting roller 32 is rotatably connected to a roller mounting frame 33. The tape-lifting cylinder 31 is connected to the roller mounting frame 33 to drive the roller mounting frame 33 toward and away from the tape mounting wheel 34. The tape-lifting roller 32 abuts against the tape mounted on the tape mounting wheel 34, preventing the tape from wobbling relative to the tape mounting wheel 34 during application.

[0049] The working process of the fully automatic tape machine is:

[0050] 1. A mold conveyor belt 8 and B mold conveyor belt 9 convey A mold and B mold respectively;

[0051] 2. When mold A is conveyed to the rear end of mold A conveyor belt 8, the mold A moving mechanism moves mold A to the positioning module, and the mold B lifting mechanism lifts mold B to the positioning module;

[0052] 3. The A-mold clamping arm cylinder drives the two A-mold positioning clamping arms 19 to clamp the A-mold, so that the four A-mold positioning claws clamp the A-mold. The B-mold clamping arm cylinder drives the two B-mold positioning clamping arms 21 to clamp the B-mold, so that the four B-mold positioning posts 38 clamp the B-mold. The B-mold lifting mechanism lifts the B-mold so that the outer circumference of the B-mold simultaneously contacts the four B-mold positioning posts 38, thereby achieving the positioning of the A-mold and B-mold.

[0053] 4. The screw translation mechanism 15 drives the positioning module to translate between the upper spindle 11 and the lower spindle 12. The center detection head extends into the spindle position. The suction wheel 21 of the upper spindle 11 descends to absorb mold A, and the suction wheel 21 of the lower spindle 12 ascends to absorb mold B. At this time, the mold A positioning clamping arm 19 and the mold B positioning clamping arm 21 of the positioning module are released. The upper spindle 11 and the lower spindle 12 move in opposite directions. According to the set center thickness, when the upper spindle 11 and the lower spindle 12 drive the mold A and mold B to move into place, they stop;

[0054] 5. The mold sheet tightening mechanism tightens molds A and B, and the tape wrapping mechanism reaches the working position. The A and B molds are taped. Then the upper spindle 11 and the lower spindle 12 rotate synchronously through the stepper motor to complete the tape wrapping. The tape cutting blade cuts the tape, and the tape folding cylinder is actuated to complete the mold making work.

[0055] 6. After the tape wrapping is completed, the suction wheel 21 of the upper spindle 11 and the suction wheel 21 of the lower spindle 12 are reset, and the die follows the suction wheel 21 of the lower spindle 12 and falls onto the die-out conveyor belt 10, and the die is output from the die-out conveyor belt 10.
