Description

Technical Field

[0001] The invention relates to a die-cutting system and a die-cutting method thereof, in particular to an adhesive part flexible die-cutting system and a die-cutting method thereof, belonging to the technical field of die-cutting systems. Background Art

[0002] A die-cutting system is a device or combination of devices specifically used for cutting materials, and is commonly used in a variety of industries such as packaging, printing, electronics, automotive, and medical. It uses high-precision dies (die cutters) and corresponding pressure devices to accurately cut, punch, or shape various materials (such as paper, plastic, leather, cloth, foam, rubber, etc.). The die-cutting system is able to cut materials with high precision according to preset graphics, shapes, and sizes. This accuracy is especially important for products that require complex shapes or fine edges, such as packaging boxes, labels, gaskets, etc.

[0003] The die-cutting system is a complex and sophisticated system, whose main components include the feeding system, die-cutting unit, receiving system and control system, among which:

[0004] The main function of the feeding system is to automatically, smoothly and accurately transport the material to be processed to the die-cutting area. It is an indispensable part of the die-cutting process and directly affects the accuracy and efficiency of subsequent die-cutting. According to different working principles, the feeding system can be divided into two types: mechanical feeding and pneumatic feeding. Mechanical feeding is to transport materials through mechanical structures, while pneumatic feeding uses air pressure to push the materials forward. The feeding system is usually equipped with rollers, traction devices and high-precision sensors to ensure that the material can enter the die-cutting station at a stable speed and accurate position. In this process, the error is controlled within a very small range, laying a solid foundation for subsequent die-cutting work.

[0005] The die-cutting unit is the core part of the die-cutting system. It includes key components such as the die-cutting knife and the bottom roller, which are responsible for performing the cutting task. The die-cutting knife is usually made of high-quality steel, with a sharp edge and good wear resistance, and can easily cut materials of various thicknesses and materials, such as paper, cardboard, plastic film, leather, etc. The bottom roller supports and guides the material to ensure that the material remains stable during the cutting process. During the die-cutting process, the die-cutting knife accurately cuts the material according to the preset shape and pattern, while the bottom roller assists in completing this process to ensure the accuracy and efficiency of the cutting.

[0006] At present, electronic product adhesives involve different sizes, and the existing die-cutting equipment can usually only produce adhesives of specific sizes one by one during operation. This production method often has the following problems:

[0007] 1. Low production efficiency

[0008] Since the die-cutting equipment needs to adjust parameters one by one to adapt to the production of adhesive parts of different sizes, it requires frequent shutdowns, die changes and debugging during the production process. These additional operations not only increase production time, but also reduce overall production efficiency, especially when mass-producing adhesive parts of different sizes. This problem is particularly prominent;

[0009] 2. Lack of flexibility

[0010] With the continuous changes in the electronic product market and the diversification of consumer demand, the size and shape of adhesive parts are also changing. If the die-cutting equipment cannot quickly adapt to these changes, it will not be able to meet the flexible needs of the market and thus lose its competitive advantage;

[0011] 3. Waste of resources

[0012] Frequent mold changes and debugging will generate a large amount of waste and defective products. These materials cannot be reused, resulting in a waste of resources. In addition, due to low production efficiency, more raw materials and energy are required to meet production needs, further exacerbating the problem of resource waste.

[0013] Therefore, a flexible die-cutting system and a die-cutting method for adhesive parts are proposed. Summary of the invention

[0049] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0050] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0051] In the prior art, the existing die-cutting equipment can usually only produce adhesive parts of specific sizes one by one during operation, which has the problems of low production efficiency, insufficient flexibility and waste of resources;

[0052] To do this, see Figure 1-Figure 8 As shown, an embodiment of the present invention provides an adhesive flexible die-cutting system, including a frame 11, two mounting seats 23 are symmetrically fixedly connected to the upper surface of the frame 11, and a die-cutting assembly 101 is installed on the mounting seat 23, and the die-cutting assembly 101 is used to perform a die-cutting operation on a flexible adhesive material strip;

[0053] The die-cutting assembly 101 includes a gantry 12, a mounting plate 13, a die-cutting cylinder 14, a die-cutting plate 16, a die-cutting knife 17, a top plate 18, a limit column 19, a tension spring 20 and a mounting seat 23;

[0054] The gantry 12 is fixedly connected to the upper surfaces of the two mounting seats 23, the mounting plate 13 is fixedly connected to the inside of the gantry 12, the die-cutting cylinder 14 is installed on the upper surface of the mounting plate 13, the top plate 18 is fixedly connected to the upper surface of the die-cutting plate 16, and the cylinder shaft of the die-cutting cylinder 14 is fixedly connected to the upper surface of the top plate 18. The die-cutting cylinder 14 pushes the top plate 18, the top plate 18 drives the die-cutting plate 16, and the die-cutting plate 16 drives the die-cutting knife 17 to move downward, so that the die-cutting action can be realized;

[0055] The limit column 19 is equidistantly slidably connected to the inside of the die-cutting plate 16, the tension spring 20 is sleeved on the outer wall of the limit column 19, the upper surface of the die-cutting knife 17 is attached to the lower surface of the die-cutting plate 16, one end of the tension spring 20 is fixedly connected to the top of the limit column 19, and the other end of the tension spring 20 is fixedly connected to the die-cutting plate 16. Since the limit column 19 is located inside the die-cutting plate 16, when the die-cutting knife 17 is installed, the limit column 19 corresponding to the position of the die-cutting knife 17 is pressed into the inside of the die-cutting plate 16, and the die-cutting knife 17 is connected to the die-cutting plate 16 by magnetic adsorption, while the position of the limit column 19 located outside the die-cutting knife 17 remains unchanged. Therefore, the position of the die-cutting knife 17 can be limited by the outer limit column 19.

[0056] In one embodiment, two guide rods 15 are symmetrically fixedly connected to the upper surface of the top plate 18, and the guide rods 15 are slidably connected to the inside of the mounting plate 13. The position of the die-cutting plate 16 can be limited by the guide rods 15. During the die-cutting process, the die-cutting plate 16 slides along the guide rods 15.

[0057] In one embodiment, the die-cutting knife 17 includes an adsorption plate 171, a magnet 172 and a knife body 173. The magnet 172 is fixedly connected to the upper surface of the adsorption plate 171, and the knife body 173 is fixedly connected to the lower surface of the adsorption plate 171. The adsorption plate 171 is adsorbed to the lower surface of the die-cutting board 16 through the magnet 172. Since the die-cutting knife 17 is adsorbed to the die-cutting board 16 through magnetic force, when die-cutting the flexible adhesive material strip, a die-cutting knife 17 of a corresponding size can be selected according to the use requirements, and then the die-cutting knife 17 is installed on the die-cutting board 16. For example, a square, round or triangular die-cutting knife 17 is selected and installed in combination on the die-cutting board 16, thereby solving the problem that the existing die-cutting equipment can only produce adhesives of specific sizes one by one.

[0058] The present invention can quickly respond to the diverse needs of the market by flexibly combining die cutters 17 of different shapes and sizes, effectively avoiding the problem of low production efficiency caused by frequent replacement of equipment or adjustment of settings. At the same time, this highly customized production capacity also reduces unnecessary material waste, improves resource utilization efficiency, and enhances the market competitiveness and environmental friendliness of the enterprise.

[0059] In one embodiment, guide rollers 22 are installed equidistantly between the two mounting seats 23, and the opposite surfaces of the two mounting seats 23 are fixedly connected to the base plate 21. The guide rollers 22 are symmetrically arranged on both sides of the base plate 21. The position of the base plate 21 corresponds to the position of the die-cutting plate 16. The guide rollers 22 can guide and support the material strip, and the base plate 21 can provide support force during die-cutting.

[0060] In one embodiment, a material unloading assembly 301 is installed inside the frame 11, and the material unloading assembly 301 is used to unload the material roll. A magnetic brake mechanism is arranged inside the material unloading assembly 301, which can provide a certain resistance during the unloading process, thereby preventing the material roll from loosening during the traction process.

[0061] The unwinding assembly 301 includes an unwinding shaft 31, a limiting bar 32, a limiting plate 33, a fixing seat 34, a base 35, a rotating disk 36, a magnetic suction cup 37, a threaded rod 38 and a magnetic block 40;

[0062] A winding roller 41 is installed inside the frame 11. The winding roller 41 and the unwinding shaft 31 are symmetrically located inside the frame 11. The outer wall of the winding roller 41 and the outer wall of the unwinding shaft 31 are both installed with a reel 42. A winding motor is installed at the roller end of the winding roller 41, which can provide winding power for the winding roller 41. During the winding process, the winding roller 41 pulls the material belt, and the material belt pulls the unwinding shaft 31. Since the unwinding shaft 31 is decelerated by magnetic force, the material belt is always kept in a taut state during the pulling process, so that the quality of die cutting can be guaranteed during the die cutting operation;

[0063] The fixing seat 34 is fixedly connected to the inside of the base 35, the base 35 is installed inside the frame 11, the limit strip 32 is symmetrically fixedly connected to the outer wall of the unwinding shaft 31, the turntable 36 is fixedly connected to one end of the unwinding shaft 31, the limit plate 33 is threadedly connected to the other end of the unwinding shaft 31, the turntable 36 is rotatably connected to the inside of the fixing seat 34, the limit plate 33 can be removed by rotating, and the reel 42 can be installed on the unwinding shaft 31 at this time, and the reel 42 is used to wind the material roll;

[0064] The magnetic suction cup 37 is slidably connected to the inside of the fixed seat 34, the magnetic block 40 is symmetrically fixedly connected to the opposite surface of the magnetic suction cup 37 and the turntable 36, the threaded rod 38 is threadedly connected to the inside of the fixed seat 34, and one end of the threaded rod 38 is rotatably connected to the magnetic suction cup 37. By rotating the threaded rod 38, since the threaded rod 38 is threadedly connected to the fixed seat 34, the threaded rod 38 can push the magnetic suction cup 37 to slide in the fixed seat 34 to adjust the distance between the magnetic suction cup 37 and the turntable 36. When the magnetic suction cup 37 is close to the turntable 36, the magnetic resistance increases, and the traction force on the material belt during the traction process increases, which is suitable for material belts with larger thickness. When the magnetic suction cup 37 is far away from the turntable 36, the magnetic resistance decreases, and the traction force on the material belt during the traction process decreases, which is suitable for material belts with smaller thickness.

[0065] Two limit rods 39 are symmetrically fixedly connected to one side of the magnetic suction cup 37 away from the turntable 36. The limit rods 39 pass through the outer wall of the fixing seat 34 and are slidably connected to the fixing seat 34. The limit rods 39 can play a limiting role so that the magnetic suction cup 37 can slide in the fixing seat 34.

[0066] In one embodiment, two positioning components 501 are installed on the mounting seat 23, and the positioning components 501 are used to realize the positioning and guiding of the material strip to prevent the material strip from being offset during the die-cutting process;

[0067] Two positioning assemblies 501 are symmetrically located on both sides of the die-cutting assembly 101, and the positioning assemblies 501 include a driving motor 51, two connecting rods 52, a screw rod 53 and two positioning clamping plates 54;

[0068] The two connecting rods 52 are symmetrically fixedly connected to the opposite surfaces of the two mounting seats 23, the two positioning clamps 54 are symmetrically slidably connected to the outer side walls of the two connecting rods 52, the two ends of the screw rod 53 are rotatably connected to the opposite surfaces of the two mounting seats 23, the driving motor 51 is installed on the outer side wall of a mounting seat 23, the output shaft of the driving motor 51 is fixedly connected to one end of the screw rod 53, the two positioning clamps 54 are symmetrically threadedly connected to the outer side wall of the screw rod 53, the screw rod 53 is a double-headed screw, the screw rod 53 is driven by the driving motor 51, the screw rod 53 drives the two positioning clamps 54 through the threads, the two positioning clamps 54 move synchronously, and then the distance between the two positioning clamps 54 can be adjusted to suit material strips of different widths.

[0069] In one embodiment, a position sensor is installed on the positioning clamp plate 54, and the position sensor can detect the position of the material belt. When the material belt is shifted due to various reasons (such as material tension change, mechanical vibration, etc.), the position sensor can quickly capture this change and immediately start the signal transmission mechanism to send the precise position shift information to the central control system wirelessly or wiredly;

[0070] After receiving the offset signal from the position sensor, the central control system will start the position correction program, and control the drive motor 51 to work according to the actual offset distance data provided by the sensor, and accurately adjust the position of the positioning clamp 54. This process not only ensures that the material belt can quickly and smoothly return to the preset correct path, but also effectively improves the stability and efficiency of the production line;

[0071] After each adjustment is completed, the position sensor will detect the position of the material strip again to ensure the accuracy of the adjustment result, and feedback the correction status to the control system, forming a closed-loop automated monitoring and adjustment process, so that the entire production line can respond more quickly and accurately when facing material strip deviation problems, thereby effectively ensuring production quality and continuity.

[0072] A method for flexible die-cutting of adhesive parts, comprising the following steps:

[0073] Step 1: Select a die-cutting knife of corresponding size according to processing requirements, and install the die-cutting knife on the die-cutting board by magnetic adsorption;

[0074] Specifically include:

[0075] Demand analysis: First, according to the specific processing requirements of the product, such as the required cutting shape, dimensional accuracy, and material type, select the corresponding size and type of die cutter;

[0076] Installation preparation: confirm the size of the die-cutting board and the installation position of the die-cutting knife, and ensure that the die-cutting knife can be accurately installed on the die-cutting board. At the same time, check whether the magnetic adsorption device works properly to ensure that the die-cutting knife can be firmly adsorbed on the die-cutting board;

[0077] Install the die-cutting knife: Use magnetic adsorption to accurately install the selected die-cutting knife on the designated position of the die-cutting board. During the installation process, ensure that the contact surface between the die-cutting knife and the die-cutting board is flat and free of impurities to ensure the cutting effect.

[0078] Step 2: Wind the material roll on the reel, and use the traction force of the winding roller to pull the flexible adhesive part to feed the material;

[0079] Specifically include:

[0080] Roll preparation: Wind the flexible adhesive parts to be processed into rolls and ensure that the surface of the rolls is flat, wrinkle-free and damage-free. At the same time, check whether the width and thickness of the rolls meet the processing requirements;

[0081] Winding the reel: Wind the material roll steadily on the reel to ensure that the material roll fits tightly on the reel to avoid loosening or slipping during the pulling process;

[0082] Traction loading: Start the traction device of the winding roller and use the traction force to smoothly pull the flexible adhesive parts on the material roll to the processing area. During the traction process, ensure that the material strip can move smoothly and continuously.

[0083] Step 3: Adjust the positions of the two positioning clamps according to the width of the material strip. With the cooperation of the drive motor and the screw rod, the two positioning clamps move synchronously, and the material strip is located between the two positioning clamps.

[0084] Specifically include:

[0085] Measure the width of the strip: Use the measuring tool to accurately measure the width of the strip to ensure the accuracy of the measurement;

[0086] Adjust the positioning clamps: According to the measured width of the material strip, adjust the positions of the two positioning clamps. With the cooperation of the drive motor and the lead screw, the two positioning clamps can move synchronously until the distance between them matches the width of the material strip;

[0087] Fixed positioning splint: After the adjustment is completed, the positioning splint is fixed at the specified position under the self-locking effect of the screw rod, so that the positioning splint can remain stable during the processing;

[0088] Step 4: Use the die-cutting cylinder to drive the die-cutting plate to move downward, and the die-cutting knife performs die-cutting on the material strip with the cooperation of the bottom plate;

[0089] Specifically include:

[0090] Start the cylinder: Start the die-cutting cylinder to drive the die-cutting plate to move downward. During the movement, the die-cutting plate descends steadily and evenly;

[0091] Cutting the material strip: When the die-cutting board drops to the specified position, the die-cutting knife cuts the material strip with the cooperation of the bottom plate. During the cutting process, ensure that the cutting accuracy and shape meet the product requirements.

[0092] Step 5: After the material strip is die-cut, the formed product adheres to the material strip, and the winding roller rewinds the die-cut material strip;

[0093] Specifically include:

[0094] Rewinding the tape: Start the rewinding device of the rewinding roller to rewind the die-cut tape. During the rewinding process, the tape is tightly attached to the reel;

[0095] Product collection: While winding, the formed product will adhere to the material belt. When it is wound to the specified length, the winding device can be stopped and the material belt with the product can be removed from the winding roller.

[0096] During use, the cutting edge of the die cutter 17 is regularly inspected and sharpened to ensure its sharpness; when a cutting size deviation occurs, check whether the installation of the die cutter 17 is loose, whether the positioning clamp 54 is displaced, etc.

[0097] When the present invention is working: according to the specific processing requirements of the product, such as the required cutting shape, dimensional accuracy and type of material, the corresponding size and type of die-cutting knife 17 is selected, and then the installation position of the die-cutting knife 17 is confirmed. During installation, the die-cutting knife 17 is first contacted with the limiting column 19, and then the die-cutting knife 17 is pushed upward to make the die-cutting knife 17 fit the die-cutting plate 16. At this time, the die-cutting knife 17 and the die-cutting plate 16 are magnetically adsorbed. By flexibly combining die-cutting knives 17 of different shapes and sizes, the problem that the existing die-cutting equipment can only produce adhesive parts of specific sizes one by one can be solved. During die-cutting, the winding power is provided by the winding roller 41. The winding roller 41 pulls the material belt during the winding process, and the material belt pulls the unwinding shaft 31. Since the unwinding shaft 31 is decelerated by magnetic force, the material belt is always kept in a taut state during the traction process, and then during the die-cutting operation, In order to ensure the quality of die-cutting, by rotating the threaded rod 38, the threaded rod 38 pushes the magnetic suction cup 37 to slide in the fixed seat 34 to adjust the distance between the magnetic suction cup 37 and the turntable 36. When the magnetic suction cup 37 is close to the turntable 36, the magnetic resistance increases, and the traction force on the material strip during the traction process increases, which is suitable for material strips with larger thickness. When the magnetic suction cup 37 is away from the turntable 36, the magnetic resistance decreases, and the traction force on the material strip during the traction process decreases, which is suitable for material strips with smaller thickness. Then, the die-cutting cylinder 14 pushes the top plate 18, and the top plate 18 drives the die-cutting plate 16, and the die-cutting plate 16 drives the die-cutting knife 17 to move downward, so that the die-cutting action can be realized. A pressure sensor is set between the die-cutting knife 17 and the bottom plate 21 to monitor and adjust the pressure in real time to ensure uniform cutting. Then, the die-cutting material strip is wound up by the winding roller 41 and wound up on the reel 42.

[0098] During the die-cutting process, according to the width of the material strip, the screw rod 53 is driven by the driving motor 51, and the screw rod 53 drives the two positioning clamps 54 through the thread. The two positioning clamps 54 move synchronously, and then the distance between the two positioning clamps 54 can be adjusted so that the two positioning clamps 54 are in contact with the two sides of the material strip, thereby realizing the positioning and guiding of the material strip. By setting scale marks on the screw rod 53, the moving distance of the positioning clamps 54 can be accurately controlled.

[0099] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of various changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
