Description

Technical Field

[0001] This invention relates to the field of stamping equipment technology, specifically to a non-release double-sided adhesive anti-sticking punching process. Background Technology

[0002] Double-sided tape die-cutting is a processing device used to precisely cut double-sided tape into the required shape and attach it to the surface of a specific workpiece. It is commonly used in industries such as electronics, automobiles, and home appliances to achieve functions such as fixing, sealing, and cushioning of parts. The non-release surface includes other parts of the mold, such as the cavity walls, core, parting surface (excluding the part used for release), guiding mechanism, and ejection mechanism. Although these parts do not directly participate in the product release process, they play an important role in the overall structure of the mold, the molding process, and the quality of the product. For example, the cavity walls and core determine the shape and dimensional accuracy of the product, the guiding mechanism ensures the accuracy and stability of mold opening and closing, and the ejection mechanism is used to eject the molded product from the mold.

[0003] According to a double-sided tape punching process proposed in patent number CN111251361B, a double-sided tape punching process is provided. Different sleeve holes are used to punch the product structure, reducing cumulative tolerances and ensuring that the dimensional tolerances of the inner and outer frames of the product can be easily controlled. The dimensions of the outer or inner frame can be adjusted separately without any related changes. The difficulty of mold adjustment is reduced and the mold adjustment time is saved. However, there is no effective solution to the problem that the tape is prone to sticking to the blade during the cutting process, and frequent cleaning is required during the cutting process. Summary of the Invention

[0004] To solve the above technical problems, the present invention is achieved through the following technical solution: a non-release double-sided adhesive anti-sticking die-cutting process, comprising the following steps: Step 1: Select a suitable double-sided tape material. Determine its thickness, adhesion, and temperature resistance performance indicators according to the usage requirements. Common double-sided tapes include acrylic and rubber types. Step 2: Place the double-sided tape flat on the die-cutting equipment, taking care to avoid wrinkles in the double-sided tape; Step 3: Including the punching equipment, after positioning is completed, start the punching equipment. The punching blade moves downward under pressure to punch the double-sided tape. Step 4: After the punching is completed, the subsequent mold moves upward with the punched double-sided tape, and at the same time, the double-sided tape is accurately pasted onto the surface of the workpiece by the pasting device. When pasting, ensure that the double-sided tape is in full contact with the surface of the workpiece to avoid air bubbles and wrinkles.

[0005] Preferably, the punching equipment includes an equipment base, an air guiding device is fixedly connected to the top of the equipment base, a punching device is fixedly connected to the air guiding device, and a conveyor belt is fixedly connected to the side of the equipment base below the punching device. The stamping device includes a fixed housing, an air guide fan rotatably connected to the side of the fixed housing, a rotating wheel fixedly connected to the side of the air guide fan, a motor drive shaft fixedly connected to the side of the air guide fan, a stripping assembly rotatably connected to the side of the rotating wheel away from the stripping assembly, a guide frame rotatably connected to the bottom of the stripping assembly, a tensioning base slidably connected to the bottom of the stripping assembly, a side of the tensioning base fixedly connected to the side of the equipment base, the top of the fixed housing communicating with the bottom of the air guide device, and a side of the cutting assembly fixedly connected to the side of the equipment base via a bracket. The raw material is placed and tensioned through the tensioning base. The motor is started, the motor drive shaft rotates, driving the air guide fan to rotate, which in turn drives the rotating wheel to rotate. The rotating wheel drives the cutting and peeling components to move. The cutting component moves downward to punch and cut the film, and the peeling component peels the film, reducing the probability of the film sticking to the bottom of the cutting component. After being punched, cut, and peeled by the peeling component, the film falls to the top of the conveyor belt for output, facilitating automated film cutting. The air guide device and air fan work together to guide cold air and cool the film during punching and cutting, thereby increasing the film's hardness and reducing its stickiness, further reducing the probability of the film sticking to the equipment. The guide frame restricts the movement trajectory of the cutting and peeling components, facilitating continuous punching and cutting.

[0006] Preferably, the rotating wheel includes a rotating seat, a connecting rod is rotatably connected to the side of the rotating seat, a crankshaft is rotatably connected to the side of the connecting rod, an air guide fan is sleeved and fixedly connected to the side of the crankshaft, a fixed bracket is rotatably connected to the side of the rotating seat away from the connecting rod, the top of the fixed bracket is fixedly connected to the inner wall side of the fixed housing through the bracket, and the bottom of the connecting rod is rotatably connected to the top of the peeling assembly.

[0007] Preferably, the cutting assembly includes a protective top, a ring-shaped cutting blade is fixedly connected to the bottom of the protective top, a sliding hole is provided on the top of the protective top, a sliding rod is fixedly connected to the side of the top of the protective top away from the sliding hole, the top of the sliding rod is rotatably connected to the side of the rotating seat through a rotating shaft, and the bottom of the ring-shaped cutting blade is slidably connected to the top of the tensioning base.

[0008] Preferably, the peeling assembly includes a sliding tube, the bottom of which is connected to a diversion tube, and the bottom of the diversion tube is connected to a peeling tube. A guide shroud is fitted and fixedly connected to the side of the sliding tube, and an air inlet adapted to the guide shroud is provided on the side of the sliding tube. The top of the sliding tube is rotatably connected to the bottom side of a connecting rod via a rotating shaft. The sliding tube is disposed on the inner wall of the sliding hole and slidably connected to a protective top. The peeling tube is disposed inside the protective top and slidably connected to it. The rotation of the motor's drive shaft drives the crankshaft to rotate, which in turn drives the air guide fan to rotate. The air guide fan causes air to flow downwards and concentrate on the inner wall of the guide shroud. Cold air enters the diversion tube along the interior of the sliding tube and is diverted. The cold air, guided by the peeling tube, blows onto the surface of the film, thereby cooling and hardening the film. The rotation of the rotating seat drives the sliding rod to move up and down, which in turn moves the protective top, which in turn drives the annular cutting. The blade moves and cuts the film taut on the surface of the taut base. The cut film falls naturally under gravity. The diverter tube moves up and down under the action of the sliding tube. The sliding tube and sliding rod are set in symmetrical positions at the center of the rotating seat. As the rotating seat rotates, it drives the sliding rod and sliding tube to move up and down in a back-and-forth motion. As the annular cutting blade rises, the peeling tube descends and pulls the film off the bottom of the annular cutting blade. The airflow inside the peeling tube blows to balance the downward pressure on the film and the cold air blows to reduce the film's stickiness, thus ensuring that the film falls on the top of the conveyor belt. This achieves periodic stamping while reducing the temperature of the film, which facilitates the hardening of the film and makes it easier to move and transport. It also reduces stickiness and increases hardness, which is conducive to stamping and cutting. The rotating seat setting increases the stamping and cutting speed compared to traditional stamping methods, which is conducive to continuous cutting.

[0009] Preferably, the guide frame includes a guide bracket, the bottom of the inner wall of the guide bracket is provided with an oblique air guide hole, and the bottom of the inner wall of the guide bracket located on one side of the oblique air guide hole is provided with a guide hole. The sliding tube is disposed inside the guide hole and is slidably connected to the oblique air guide hole. The top of the guide bracket is fixedly connected to the bottom of the fixed housing. The oblique air guide hole is located above the protective top. The setting of the guide hole facilitates the limitation of the movement trajectory of the protective top and the sliding tube, and guides the air introduced from above through the oblique air guide hole, so that the air can flow along the inner wall of the oblique air guide hole, thereby allowing the cold air to flow along the top of the protective top. The cold air flowing along the top of the protective top cools the area around the film, thereby facilitating the cooling and hardening of the outer edge of the film after stamping and cutting. Cooling and hardening near the film cutting position helps to ensure the cutting quality and facilitates the assembly line cutting of the film.

[0010] Preferably, the air guiding device includes a fixed base, an air inlet connector is fixedly connected to the top of the fixed base, a rotating pipe is rotatably connected to the bottom of the air inlet connector, an air vent is provided on the side of the rotating pipe, a scattering fan blade is fixedly connected to the side of the rotating pipe at the position of the air vent, a guide blade is fixedly connected to the end of the scattering fan blade away from the rotating pipe, the side of the fixed base is fixedly connected to the side of the equipment base, and the bottom of the fixed base communicates with the top of the fixed housing.

[0011] Preferably, the conveyor belt includes a fixed base, the top of which is fixedly connected to a fixed end of the conveyor belt. A guide block is fixedly connected to the side of the conveyor belt. A guide pipe is fixedly connected to the side of the fixed base below the conveyor belt. A sieve plate is fixedly connected to the inner wall of the guide pipe. An air vent is provided on the side of the sieve plate below it. The side of the fixed base is fixedly connected to the side of the equipment base. The conveyor belt is positioned below the stripping pipe. Nitrogen is input through an air inlet connector, and then through a rotating pipe and released through a vent hole. Air is ejected through the vent hole and flows along the surface of the scattering fan blades. The air flow is guided by the guide blades and dispersed. The spray fan blades rotate, causing nitrogen to be sprayed downwards. This facilitates the downward movement of the nitrogen, and the vent holes allow the nitrogen to vaporize and mix with air to cool and harden the film. After the film is cut, it falls directly onto the top of the conveyor belt for output. The guide blocks facilitate the guidance of the conveyor belt, reducing the probability of deviation and facilitating film transport. The cut fragments fall under the influence of gravity, passing along the side of the conveyor belt and into the inside of the guide tube. The fragments land on the top of the screen plate, where air carries the fragments through the screen plate for filtration. This facilitates the collection of debris under the guidance of the guide tube. The air is released through the vent holes, allowing the debris to be collected in a concentrated manner inside the guide tube.

[0012] This invention provides a non-release double-sided adhesive anti-sticking die-cutting process. It has the following beneficial effects: 1. The non-release double-sided adhesive's anti-sticking die-cutting process incorporates a motor. The motor's drive shaft rotates, which in turn drives an air guide fan. The air guide fan's rotation further drives a rotating wheel, which in turn moves the cutting and peeling components in tandem. During this process, the cutting component moves downwards, precisely punching and cutting the adhesive sheet; simultaneously, the peeling component effectively peels off the cut adhesive sheet, significantly reducing the likelihood of the sheet sticking to the bottom of the cutting component. After punching and cutting and peeling, the adhesive sheet falls naturally under gravity, eventually landing on the surface of the conveyor belt and being stably output. This series of actions enables continuous, assembly-line cutting of the adhesive sheet. The equipment uses a combination of an air guide device and an air guide fan to directionally guide cool air, cooling the adhesive sheet during punching and cutting. This cooling process helps increase the hardness of the adhesive sheet while reducing its surface stickiness, further minimizing adhesion to the equipment. The entire mechanism is also equipped with a guide frame to constrain the movement trajectory of the cutting and stripping components, thereby ensuring the accuracy and stability of the action and facilitating continuous and efficient stamping and cutting operations.

[0013] 2. The non-release double-sided adhesive's anti-sticking die-cutting process includes an air guide fan. The motor's drive shaft rotates, causing the crankshaft to rotate, which in turn rotates the air guide fan. The fan's rotation causes air to flow downwards and concentrate on the inner wall of the air guide shroud. The cold air enters the distribution tube along the sliding tube and is then distributed. Guided by the peeling tube, the cold air blows onto the surface of the adhesive sheet, cooling and hardening it. The rotating base rotates, causing the sliding rod to move up and down. This movement of the sliding rod moves the protective top, which in turn moves the annular cutting blade, cutting the adhesive sheet stretched on the surface of the tension base. The cut adhesive sheet falls naturally under gravity. The distribution tube moves up and down under the influence of the sliding tube, and... The sliding tube and sliding rod are positioned symmetrically at the center of the rotating seat. As the rotating seat rotates, they drive the sliding rod and sliding tube to move up and down relative to each other. During the upward movement of the annular cutting blade, the descending peeling tube causes the film to detach from the bottom of the annular cutting blade. The airflow inside the peeling tube evens out the downward pressure on the film, and the cold air reduces the film's stickiness, ensuring that the film lands on top of the conveyor belt. This achieves periodic stamping while reducing the film's temperature, facilitating film hardening for subsequent movement and transportation. It also reduces adhesion and increases hardness, making stamping and cutting easier. Furthermore, the rotating seat configuration increases the stamping and cutting speed compared to traditional stamping methods, facilitating continuous cutting.

[0014] 3. The non-release double-sided adhesive's anti-sticking punching process includes guide holes. These guide holes help limit the movement trajectory of the protective top and sliding tube, and guide the air introduced from above through oblique air guide holes. This allows the air to flow along the inner wall of the oblique air guide holes, causing cold air to flow along the top of the protective top. The cold air flowing along the top of the protective top cools the area around the film, facilitating the cooling and hardening of the outer edge of the film after punching and cutting. Cooling and hardening near the cutting position helps ensure cutting quality and enables automated film cutting.

[0015] 4. The non-release double-sided adhesive's anti-sticking die-cutting process features a rotating tube. Nitrogen is input through the air inlet and then released through the vent hole. Air flows along the surface of the scattering fan blades after being ejected through the vent hole. The airflow is guided by the guide vanes, causing the scattering fan blades to rotate. This rotation of the scattering fan blades drives the nitrogen downwards, facilitating its downward movement. The vent hole also facilitates the vaporization of nitrogen and its mixing with air to cool and harden the adhesive sheet. After cutting, the adhesive sheet falls directly onto the top of the conveyor belt for output. The guide block facilitates the conveyor belt's guidance, reducing the probability of deviation and facilitating the transport of the adhesive sheet. The cut fragments, under gravity, fall through the side of the conveyor belt into the inside of the guide tube and onto the top of the sieve plate. Air carries the fragments through the sieve plate for filtration, facilitating the collection of debris under the guidance of the guide tube. The air is released through the vent hole, allowing the debris to be collected centrally within the guide tube. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] For the first embodiment, please refer to... Figures 1-2 This invention provides a technical solution: a non-release double-sided adhesive anti-sticking die-cutting process, comprising the following steps: Step 1: Select a suitable double-sided tape material. Determine its thickness, adhesion, and temperature resistance performance indicators according to the usage requirements. Common double-sided tapes include acrylic and rubber types. Step 2: Place the double-sided tape flat on the die-cutting equipment, taking care to avoid wrinkles in the double-sided tape; Step 3: After positioning is completed, start the punching equipment. The punching blade moves downward under pressure to punch the double-sided tape. Step 4: After the punching is completed, the subsequent mold moves upward with the punched double-sided tape, and at the same time, the double-sided tape is accurately pasted onto the surface of the workpiece by the pasting device. When pasting, ensure that the double-sided tape is in full contact with the surface of the workpiece to avoid air bubbles and wrinkles.

[0020] The punching equipment includes an equipment base 1, an air guide device 2 is fixedly connected to the top of the equipment base 1, a punching device 3 is fixedly connected to the air guide device 2, and a conveyor belt 5 is fixedly connected to the side of the equipment base 1 below the punching device 3. The stamping device 3 includes a fixed housing 301, an air guide fan 302 rotatably connected to the side of the fixed housing 301, a rotating wheel 303 fixedly connected to the side of the air guide fan 302, a drive shaft of a motor 308 fixedly connected to the side of the air guide fan 302, a peeling component 305 rotatably connected to the side of the rotating wheel 303 away from the peeling component 305, a guide frame 306 rotatably connected to the side of the rotating wheel 303 away from the peeling component 305, a tensioning base 307 slidably connected to the bottom of the peeling component 305, a side of the tensioning base 307 fixedly connected to the side of the equipment base 1, a top of the fixed housing 301 communicating with the bottom of the air guide device 2, and a side of the cutting component 304 fixedly connected to the side of the equipment base 1 via a bracket.

[0021] The raw material is placed and tightened by the tensioning base 307. The motor 308 is started, and the drive shaft of the motor 308 rotates, driving the air guide fan 302 to rotate. The rotation of the air guide fan 302 drives the rotating wheel 303 to rotate, which in turn moves the cutting assembly 304 and the peeling assembly 305. The cutting assembly 304 moves downwards to punch and cut the film, and the peeling assembly 305 peels the film, reducing the probability of the film sticking to the bottom of the cutting assembly 304. The film undergoes punching, cutting, and peeling. The peeling action of component 305 causes the film to fall and land on the top of conveyor belt 5 for output, which facilitates the production line cutting of film. The air guide device 2 and the air guide fan 302 work together to guide the cold air, which cools the film while it is being punched and cut, thereby increasing the hardness of the film and reducing its stickiness, thus reducing the probability of the film sticking to the equipment. The guide frame 306 restricts the movement trajectory of the cutting component 304 and the peeling component 305, which facilitates continuous punching and cutting.

[0022] For the second embodiment, please refer to... Figures 1-5 Based on the first embodiment, the present invention provides a technical solution: the rotating wheel 303 includes a rotating seat 3031, a connecting rod 3032 is rotatably connected to the side of the rotating seat 3031, a crankshaft 3033 is rotatably connected to the side of the connecting rod 3032, a fixed bracket 3035 is rotatably connected to the side of the rotating seat 3031 away from the connecting rod 3032, the top of the fixed bracket 3035 is fixedly connected to the inner wall side of the fixed housing 301 through the bracket, and the bottom of the connecting rod 3032 is rotatably connected to the top of the peeling assembly 305.

[0023] The cutting assembly 304 includes a protective top 3041, a ring-shaped cutting blade 3042 fixedly connected to the bottom of the protective top 3041, a sliding hole 3043 opened on the top of the protective top 3041, a sliding rod 3044 fixedly connected to the side of the top of the protective top 3041 away from the sliding hole 3043, the top of the sliding rod 3044 is rotatably connected to the side of the rotating seat 3031 through a rotating shaft, and the bottom of the ring-shaped cutting blade 3042 is slidably connected to the top of the tensioning base 307.

[0024] The stripping assembly 305 includes a sliding tube 3051, a diversion tube 3052 connected to the bottom of the sliding tube 3051, a stripping tube 3053 connected to the bottom of the diversion tube 3052, an air guide shroud 3054 sleeved and fixedly connected to the side of the sliding tube 3051, an air inlet adapted to the air guide shroud 3054 opened on the side of the sliding tube 3051, the top of the sliding tube 3051 rotatably connected to the bottom side of the connecting rod 3032 via a pivot, the sliding tube 3051 is disposed on the inner wall of the sliding hole 3043 and slidably connected to the protective top 3041, and the stripping tube 3053 is disposed inside the protective top 3041 and slidably connected to the protective top 3041.

[0025] The drive shaft of motor 308 rotates, causing crankshaft 3033 to rotate. Cold air enters the interior of the distributor pipe 3052 through the interior of sliding tube 3051 for distribution. The cold air is guided by peeling tube 3053 and blows onto the surface of the film, thereby cooling and hardening the film. The rotation of rotating seat 3031 drives sliding rod 3044 to move up and down. The up and down movement of sliding rod 3044 drives protective top 3041 to move. The movement of protective top 3041 drives annular cutting blade 3042 to move and cut the film stretched on the surface of tensioning base 307. The cut film falls naturally under the action of gravity. The distributor pipe 3052 moves up and down under the action of sliding tube 3051 and is set at the center of rotating seat 3031 through sliding tube 3051 and sliding rod 3044. The symmetrical position allows the rotating seat 3031 to rotate while simultaneously driving the sliding rod 3044 and sliding tube 3051 to move up and down relative to each other. As the annular cutter 3042 rises, the descending peeling tube 3053 causes the film to fall off from the bottom of the annular cutter 3042. The airflow inside the peeling tube 3053 balances the downward pressure on the film, and the cold air reduces the film's stickiness, ensuring that the film falls on the top of the conveyor belt 5. This achieves periodic stamping while reducing the film's temperature, facilitating film hardening for subsequent movement and transportation. It also reduces adhesion and increases hardness, making stamping and cutting easier. Furthermore, the rotating seat 3031 increases the stamping and cutting speed compared to traditional stamping methods, facilitating continuous cutting.

[0026] Third embodiment, please refer to Figures 1-6Based on the second embodiment, the present invention provides a technical solution: the guide frame 306 includes a guide bracket 3061, the bottom of the inner wall of the guide bracket 3061 is provided with an oblique air guide hole 3062, the bottom of the inner wall of the guide bracket 3061 located on one side of the oblique air guide hole 3062 is provided with a guide hole 3063, the sliding tube 3051 is disposed inside the guide hole 3063 and is slidably connected to the oblique air guide hole 3062, the top of the guide bracket 3061 is fixedly connected to the bottom of the fixed housing 301, and the oblique air guide hole 3062 is disposed above the protective top 3041.

[0027] The guide hole 3063 is designed to limit the movement trajectory of the protective top 3041 and the sliding tube 3051, and guides the air introduced from above through the oblique air guide hole 3062, so that the air can flow along the inner wall of the oblique air guide hole 3062, thereby allowing the cold air to flow along the top of the protective top 3041. The cold air flowing along the top of the protective top 3041 cools the area around the film, thereby facilitating the cooling and hardening of the outer edge of the film after stamping and cutting. Cooling and hardening near the film cutting position helps to ensure the cutting quality and facilitates the assembly line cutting of film.

[0028] For the fourth embodiment, please refer to [link / reference]. Figures 1-8 Based on the third embodiment, the present invention provides a technical solution: the air guiding device 2 includes a fixed base 201, an air inlet connector 202 is fixedly connected to the top of the fixed base 201, a rotating pipe 203 is rotatably connected to the bottom of the air inlet connector 202, an air vent 204 is provided on the side of the rotating pipe 203, a scattering fan blade 205 is fixedly connected to the side of the rotating pipe 203 at the position on the side of the air vent 204, a guide blade 206 is fixedly connected to the end of the scattering fan blade 205 away from the rotating pipe 203, the side of the fixed base 201 is fixedly connected to the side of the equipment base 1, and the bottom of the fixed base 201 is connected to the top of the fixed housing 301.

[0029] The conveyor belt 5 includes a fixed base 501, the fixed end of the conveyor belt 502 is fixedly connected to the top of the fixed base 501, the guide block 503 is fixedly connected to the side of the conveyor belt 502, the guide tube 504 is fixedly connected to the side of the fixed base 501 below the conveyor belt 502, the screen plate 505 is fixedly connected to the inner wall side of the guide tube 504, the air outlet 506 is opened on the side of the screen plate 505 below the screen plate 505, the side of the fixed base 501 is fixedly connected to the side of the equipment base 1, and the conveyor belt 502 is located below the stripping tube 3053.

[0030] Nitrogen gas is input through inlet connector 202, then through rotating pipe 203 and released through vent hole 204. Air is ejected through vent hole 204 and flows along the surface of diffuser blade 205. Guided by guide vane 206, the airflow drives the diffuser blade 205 to rotate, which in turn propels nitrogen downwards. This downward movement of nitrogen and the vent hole 204 facilitate nitrogen vaporization and mixing with air to cool and harden the film. After the film is cut, it falls directly onto the conveyor belt. The top of the conveyor belt 502 is used for moving output. The guide block 503 is set to facilitate the guidance of the conveyor belt 502, thereby reducing the probability of deviation and facilitating the transport of film. The cut fragments fall into the inside of the guide tube 504 under the action of gravity, passing the side of the conveyor belt 502. The fragments fall on the top of the screen plate 505. The air carries the fragments through the screen plate 505 for filtration, thereby facilitating the collection of debris under the guidance of the guide tube 504. The air is released through the air outlet 506, thereby facilitating the centralized collection of debris inside the guide tube 504.

[0031] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
