Description

Technical Field

[0001] This application belongs to the field of mechanical manufacturing, and in particular relates to an automatic adhesive tape tearing device. Background Technology

[0002] In the current electronics industry, workpieces such as metal sheets often need to be bonded together. An adhesive substance is applied to the surface of the workpiece, and tape is used to cover the adhesive substance. The tape is then removed during bonding, allowing the workpieces to be bonded to each other and to other components.

[0003] The existing adhesive tape removal process mostly involves manual removal of the tape, which has a low degree of automation, is time-consuming and labor-intensive, results in high labor intensity for workers, and has low production efficiency.

[0004] Furthermore, during the process of tearing off the adhesive tape, the tape easily generates static electricity and sticks to the worker's hands. After the tape is torn off, it is difficult to automatically put the torn tape into the trash can, making it impossible to achieve continuous tape tearing operation and resulting in low efficiency. Summary of the Invention

[0005] In order to improve or solve at least one of the problems mentioned in the background art, this application provides an automatic adhesive paper tearing device.

[0006] This automatic adhesive tape removal device is used to remove adhesive tape from workpieces. The device includes a turntable feeding mechanism comprising a controlled rotating turntable with a first workstation plate on which the workpiece can be mounted; a pick-and-place mechanism including a suction nozzle capable of picking up the workpiece and configured to be displaceable; and a positioning and storage mechanism including a fixed workstation, a storage box, and an anti-static nozzle. The fixed workstation is used to fix the workpiece on a horizontal plane, and the suction nozzle can transport the workpiece from the turntable feeding mechanism to the fixed workstation. The storage box includes a tape-tearing mechanism comprising tape grippers that can be controlled to open and close. Grooves are provided through the opposite side walls of the storage box. The tape grippers can pass through the grooves to clamp the tape at the fixed position and can retract horizontally into the storage box so that the tape falls into the storage box after the tape grippers are released. An anti-static nozzle blows air towards the tape grippers located in the storage box to remove static electricity from the tape grippers. The position of the tape grippers is below the highest point of the side wall of the storage box.

[0007] In at least one embodiment, the turntable feeding mechanism further includes a plurality of first workpiece positioning shafts, which are connected to the turntable and pass through the first workstation plate. When the workpiece is mounted on the first workstation plate, the workpiece abuts against the cylindrical surfaces of the plurality of first workpiece positioning shafts, thereby fixing the workpiece relative to the first workstation plate in a horizontal plane.

[0008] In at least one embodiment, the turntable feeding mechanism further includes a second station plate, with the center of the turntable as the center of symmetry, and the first station plate and the second station plate are symmetrically arranged on both sides of the axis of the turntable.

[0009] In at least one embodiment, the automatic adhesive paper tearing device further includes a lifting mechanism, which includes a lifting shaft configured to perform lifting motion, the lifting shaft abutting against the bottom surface of the first workstation plate, such that the lifting shaft can drive the first workstation plate to perform lifting motion.

[0010] In at least one embodiment, the suction nozzle includes a first suction nozzle and a second suction nozzle that are relatively stationary, wherein the first suction nozzle is aligned with the first workstation plate, and the second suction nozzle is aligned with the fixed workstation of the positioning and storage mechanism.

[0011] In at least one embodiment, the nozzle has its opening facing downwards, allowing the workpiece to be vertically lifted.

[0012] In at least one embodiment, the destatic nozzle is an ion air nozzle, which is capable of blowing out ion air.

[0013] In at least one embodiment, the adhesive tape tearing mechanism further includes a first cylinder that drives the adhesive tape gripper through the storage box and back into the storage box.

[0014] This application uses a material handling mechanism to transfer the position of the workpiece, and a positioning and storage mechanism in conjunction with a tape-tearing mechanism to facilitate the removal of the tape from the workpiece after it is positioned. This achieves automatic loading, tape-tearing, and unloading of the workpiece, and realizes automation and assembly line operation of the tape-tearing process, thereby improving the efficiency and automation level of tape-tearing.

[0028] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.

[0029] An adhesive substance is applied to workpiece 6, and adhesive tape 61 covers the adhesive substance. This application provides an automatic adhesive tape removal device for removing the adhesive tape 61 from workpiece 6 (see [link]). Figure 6 This exposes the sticky substance on workpiece 6. See also Figure 1 The automatic adhesive paper tearing device includes a turntable feeding mechanism 1, a lifting mechanism 2, a material picking and dispensing mechanism 3, a positioning and storage mechanism 4, and an adhesive paper tearing mechanism 5.

[0030] See Figure 2The turntable feeding mechanism 1 may include a turntable 11, a rotary cylinder 12, a first work station plate 13, a second work station plate 14, a first work station guide shaft 15, and a second work station guide shaft 16.

[0031] The rotary cylinder 12 is used to drive the rotary disk 11 to rotate. With the center of the rotary disk 11 as the center of symmetry, the first work plate 13 and the second work plate 14 are vertically movable and centrally symmetrically arranged on both sides of the axis of the rotary disk 11.

[0032] The first station guide shaft 15 is connected to the rotary disk 11 and passes through the first station plate 13. The second station guide shaft 16 is connected to the rotary disk 11 and passes through the second station guide plate 14. Of course, multiple first station guide shafts 15 and multiple second station guide shafts 16 can be provided to avoid relative rotation between the lifting plate and the guide shaft on the horizontal plane.

[0033] See Figure 2 The turntable feeding mechanism 1 may further include multiple first workpiece positioning shafts 17, which are connected to the turntable 11 and pass through the first station plate 13. The positions of the first workpiece positioning shafts 17 can be arranged according to the structure of the workpiece 6. When the workpiece 6 is mounted on the first station plate 13, the workpiece 6 abuts against the cylindrical surface of the first workpiece positioning shaft 17, so that the workpiece 6 is fixed in the horizontal plane by the first workpiece positioning shaft 17, thereby completing the positioning of the workpiece 6 on the first station plate 13. Similarly, the turntable feeding mechanism 1 may further include a second workpiece positioning shaft 18, which is arranged in the same way as the first workpiece positioning shaft 17. In the plane, the positions of the second workpiece positioning shaft 18 and the first workpiece positioning shaft 17 are centrally symmetrical about the center of the turntable 11.

[0034] Of course, more workstations, guide shafts, and positioning shafts can be set on the rotary table 11. The angle of rotation of the rotary table each time can be the ratio of 360° to the number of workstations.

[0035] In one embodiment of this application, the rotary feeding mechanism 1 may further include a sensor 19. A column structure may be provided at the axis of the rotary disk 11, and the sensor 19 is connected to the column structure. The sensor 19 can be used to detect the position information of the workpiece and provide a signal to start the material picking step of the suction nozzle 31 (described later).

[0036] See Figure 3The lifting mechanism 2 may include a lifting shaft 21 and a lifting cylinder 22. The lifting shaft 21 is configured to perform lifting movements, and the lifting cylinder 22 drives the lifting shaft 21 to perform lifting movements. The lifting shaft 21 is configured to abut against the bottom surface of the first workstation plate 13, so that the lifting shaft 21 can drive the first workstation plate 13 to perform lifting movements. When the drive disk 11 rotates 180°, causing the second workstation plate 14 to rotate to the position of the first workstation plate 13, the lifting shaft 21 can abut against the bottom surface of the second workstation plate 14, so that the lifting shaft 21 can drive the second workstation plate 14 to perform lifting movements.

[0037] For example, multiple workpieces 6 can be loaded onto the first workstation plate 13 at one time. The position of the first workstation plate 13 can be controlled by controlling the lifting shaft 6, thereby controlling the position of the workpieces 6, so that multiple workpieces 6 can be taken away in sequence, increasing work efficiency.

[0038] See Figure 4 The material handling mechanism 3 includes a suction nozzle 31, which is used to pick up the workpiece 6. The suction nozzle 31 is configured to be movable; for example, the suction nozzle 31 can be disposed on a slider 32, and the slider 32 can be slidably connected to the track 33.

[0039] In one embodiment of this application, the suction nozzle 31 can transport the workpiece 6 from the turntable feeding mechanism 1 to the fixed station 41 of the positioning and storage mechanism 4 (described later), and transport the workpiece from the fixed station 41 to other locations, such as to the assembly station (not shown in the figure). Two workpieces 6 with the adhesive tape 61 removed can be bonded together to complete the assembly of the workpiece.

[0040] The suction nozzle 31 may include a first suction nozzle 311 and a second suction nozzle 312 disposed on the same slider and kept relatively stationary to speed up the loading and unloading rhythm. For example, the distance between the two suction nozzles can be controlled so that when the first suction nozzle 311 picks up the workpiece 6 at the fixed station 41, the second suction nozzle 312 picks up the workpiece 6 at the turntable feeding mechanism 1; then, the first suction nozzle 311 moves to the assembly station (not shown in the figure) and places the workpiece at the assembly station, while the second suction nozzle 312 moves to the fixed station 41 and places the workpiece at the fixed station 41.

[0041] The nozzle 31 can be oriented downwards, allowing the workpiece 6 to be vertically lifted.

[0042] See Figure 5 , Figure 6 The positioning and storage mechanism 4 includes a fixed station 41, a storage box 42, a slot 43, and an anti-static nozzle 44. The adhesive paper tearing mechanism 5 may include an adhesive paper gripper 51, a first cylinder 52, and a second cylinder 53.

[0043] The fixed station 41 is used to restrict the movement of the workpiece 6 on the horizontal plane. The opposite side walls of the storage box 42 are provided with through slots 43, through which the adhesive tape gripper 51 passes. The gripper 51 passes through the slots 43 into the storage box 42 and clamps the adhesive tape 61 of the workpiece 6 on the fixed station 41. Subsequently, the adhesive tape gripper 51 retracts horizontally into the storage box 42, and when released, the adhesive tape 61 falls into the storage box 42.

[0044] Compared to the absence of grooves on the side walls, the design of groove 43 simplifies the movement of the tape gripper 51, eliminating the need for lifting and lowering. The position of the tape gripper 51 is lower than the highest point of the side wall of the storage box 42, so that when the tape gripper 51 retracts into the storage box 42, there are only openings at groove 43 in the side walls of the storage box around the tape gripper 51, making it easier for the tape 61 to fall into the storage box 42.

[0045] See Figure 6 The adhesive tape 61 has a portion extending out of the workpiece 6; this extended portion is called the protrusion 611. Figure 6 In the process, the adhesive tape 61 is located on the bottom surface of the workpiece 6, and the protrusion 611 extends out of one end of the workpiece 6. The adhesive tape gripper 51 is used to clamp the protrusion 611 of the adhesive tape 61.

[0046] The anti-static nozzle 44 can blow air towards the adhesive tape clamp 51 in the storage box 42 to remove static electricity from the adhesive tape 61 clamped by the adhesive tape clamp 51, preventing the adhesive tape 61 from being difficult to fall off due to static electricity. The anti-static nozzle 44 can be an ionizing nozzle, which can blow out ionized air to remove static electricity from the adhesive tape 61. It can be understood that compared with the design scheme where the adhesive tape clamp needs to move up and down, the design of the adhesive tape clamp 51 moving in the horizontal direction in this embodiment allows the anti-static nozzle 44 to be fixedly set above the storage box 42. The distance between the anti-static nozzle 44 and the adhesive tape 61 in the height direction can be set to be shorter and fixed, improving the anti-static effect.

[0047] For example, the first cylinder 52 is used to drive the adhesive tape gripper 51 to extend from the slot 43 and retract from the slot 43. The second cylinder 53 is used to drive the adhesive tape gripper 51 to close and open.

[0048] This application does not limit the power source of the aforementioned components. For example, in addition to the cylinder drive mentioned above, it can also be driven by an electric motor.

[0049] For example, the operation of the automatic adhesive tape tearing device provided in this application can be as follows.

[0050] Workpiece 6 is installed in the first workstation plate 13, the rotary disk 11 rotates 180°, and the lifting shaft 21 controls the height of the first workstation plate 13. At the same time, workpiece 6 can be installed in the second workstation plate 14, waiting to be loaded after rotation.

[0051] The suction nozzle 31 moves the workpiece 6 to the fixed station 41, and the adhesive tape gripper 51 clamps the adhesive tape 61 on the workpiece 6; the suction nozzle 31 continues to move, the adhesive tape gripper 51 remains stationary, the adhesive tape 61 is torn off and is located in the adhesive tape gripper 51; the adhesive tape gripper 51 retracts, the anti-static nozzle 44 blows the adhesive tape 61, and then the adhesive tape gripper 51 opens, allowing the adhesive tape 61 to fall into the storage box 42.

[0052] The automatic adhesive tape tearing device provided in this application realizes the automatic feeding, adhesive tape tearing, and unloading processes of workpieces, achieving automation and assembly line operation of the adhesive tape tearing process, improving the efficiency and automation level of adhesive tape tearing, and having outstanding stability and durability, freeing human resources from repetitive manual labor; this application removes static electricity on the adhesive tape by using an antistatic nozzle, solving the problem that existing adhesive tape generates static electricity after being torn off, making it difficult to effectively enter the storage box.

[0053] For example, the adhesive tape 61 can be a film, paper, or other material.

[0054] Exemplary embodiments of this application are described below with reference to the accompanying drawings. It should be understood that these specific descriptions are for teaching those skilled in the art how to implement this application only, and are not intended to exhaustively describe all possible methods of this application, nor to limit the scope of this application.
