Description

Technical Field

[0001] This utility model relates to the field of 3M tape die-cutting technology, and more specifically, to an automatic positioning die-cutting device for 3M adhesive tape. Background Technology

[0002] Precision adhesive products such as 3M tapes typically require die-cutting equipment to be processed into specific shapes and sizes to meet the application needs of fields such as electronics and medical. Traditional die-cutting equipment mainly consists of an unwinding mechanism, a conveyor roller group, a die-cutting mechanism, and a rewinding mechanism. Its working principle is that the drive system continuously conveys the tape, and when the tape reaches the preset position, the die-cutting mechanism presses down to complete the die-cutting operation.

[0003] However, such conventional equipment has many technical limitations in actual operation: First, its positioning system mostly uses mechanical baffles or simple photoelectric sensors, which makes it difficult to guarantee positioning accuracy within ±0.5mm when the tape stretches and deforms due to tension changes.

[0004] Secondly, the equipment lacks an intelligent tension adjustment system, which cannot automatically adjust the pressure between the rollers according to the different thicknesses of the tape. This can easily lead to the stretching and deformation of thin tapes or the slippage of thick tapes. More importantly, existing equipment will have adhesive residue problems during long-term operation, and the traditional manual shutdown cleaning method seriously restricts the production efficiency of the equipment.

[0005] Regarding punching quality, the lack of an effective material clamping device makes the tape prone to displacement during punching, resulting in irregular cuts and other problems. Furthermore, these machines generally lack intelligent detection and automatic compensation functions. When material misalignment or abnormal tension occurs, manual intervention is required to restore production. This not only increases the workload of operators but also affects product consistency and yield. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0024] Please see Figures 1-4In this utility model, an automatic positioning and punching device for 3M adhesive tape includes a punching frame 1. A take-up frame 2 and an unwind frame 3 are respectively installed on the left and right sides of the punching frame 1. A drive motor 4 is installed on the back of both the take-up frame 2 and the unwind frame 3. Two electric push rods 5 are fixedly installed inside the punching frame 1. A mounting frame 6 is installed on the top of the electric push rods 5. A stainless steel mirror roller 7 is rotatably installed on the inner wall of the mounting frame 6. An auxiliary component 8 is provided on the mounting frame 6. A punching cylinder 9 is fixedly installed on the top of the punching frame 1. The bottom end of the punching cylinder 9 penetrates and extends into the interior of the punching frame 1. A punching cutter 10 is installed on the bottom line of the punching cylinder 9. An industrial camera 11 is installed on the inner wall of the punching frame 1. A processor 12 is integrated inside the punching frame 1. The drive motor 4, auxiliary component 8, punching cylinder 9 and industrial camera 11 are all signal connected to the processor 12.

[0025] The auxiliary component 8 includes a miniature cylinder 801, which is fixedly mounted on the mounting bracket 6. A scraper 802 is fixedly mounted on the output end of the miniature cylinder 801, and the scraper 802 is located on the left side of the stainless steel mirror roller 7.

[0026] Two springs 15 are fixedly installed on the bottom line of the punching cylinder 9. A limit roller 16 is installed at the bottom of the spring 15. The limit roller 16 is located on the top of the stainless steel mirror roller 7. An anti-slip pad 18 is connected to the outer ring of the limit roller 16. A telescopic sleeve 17 is provided inside the spring 15. The bottom end of the telescopic sleeve 17 is connected to the top of the limit roller 16.

[0027] When 3M adhesive tape die-cutting is required, the operator first installs the tape roll on the unwinding frame 3, and then pulls the tape head to the surface of the stainless steel mirror roller 7, passes it under the limit roller 16 and fixes it to the take-up frame 2.

[0028] After the equipment is started, the drive motor 4 drives the unwinding frame 3 and the winding frame 2 to operate synchronously, so that the tape is conveyed with constant tension. At this time, the industrial camera 11 captures the pattern or mark on the tape surface in real time and transmits the image to the processor 12 for analysis. The processor 12 adjusts the height of the mounting frame 6 through the electric push rod 5 according to the image recognition result, so that the gap between the stainless steel mirror roller 7 and the limit roller 16 adapts to the tape thickness to ensure stable tension. At the same time, the buffer structure composed of the spring 15 and the telescopic sleeve 17 can dynamically compensate for the tape thickness fluctuation to avoid damage or slippage.

[0029] During the conveyor belt transport process, the miniature cylinder 801 in the auxiliary component 8 pushes the scraper 802 to stick to the surface of the stainless steel mirror roller 7 to scrape off residual adhesive stains and keep the roller surface clean. When the industrial camera 11 detects the tape positioning mark, the processor 12 immediately controls the punching cylinder 9 to press down and drive the punching cutter 10 to complete the precise punching. At this time, the limit roller 16 presses down synchronously to fix the tape and prevent displacement.

[0030] The die-cut adhesive tape is wound up by the take-up frame 2, and the drive motor 4 adjusts the winding speed according to the instructions of the processor 12 to ensure continuous operation without accumulation.

[0031] In this invention, the drive motor 4 drives the unwinding frame 3 and the rewinding frame 2 to operate synchronously. The electric push rod 5 adjusts the height of the mounting frame 6 to maintain the optimal distance between the stainless steel mirror roller 7 and the limiting roller 16, ensuring stable tape tension. The industrial camera 11 monitors the tape position in real time and transmits the data to the processor 12 for intelligent analysis. The processor controls the punching cylinder 9 to drive the punching cutter 10 to complete a high-precision punching operation. The auxiliary component 8 continuously cleans the surface of the stainless steel mirror roller 7. The buffer mechanism composed of the spring 15 and the telescopic sleeve 17 automatically compensates for changes in tape thickness. This equipment integrates automatic positioning, tension adjustment, surface cleaning, and precise punching functions, featuring high precision, high stability, and intelligence. It is particularly suitable for the mass production needs of precision adhesive products.

[0032] Please see Figure 1 and 4 The punching frame 1 is equipped with an indicator light 13, which is connected to the processor 12 via signal.

[0033] In this invention, after the punching is completed, the processor 12 will simultaneously control the indicator light 13 to flash. The indicator light 13 can serve as a reminder to the operator so that they can understand the status of the equipment in a timely manner.

[0034] Please see Figure 2 and 4 Two lights 14 are installed on the inner wall of the punching frame 1, and the two lights 14 are located on the left and right sides of the industrial camera 11 respectively.

[0035] In this invention, the lighting lamp 14 is tilted to provide a light source for the industrial camera 11 during operation, thereby enabling more precise image acquisition and automatic positioning.

[0036] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
