Description

Technical Field

[0001] The present invention relates to the technical field of double-sided adhesive punching, and specifically to a punching and pasting process for double-sided adhesive on the non-release surface of a mold. Background Art

[0002] The punching and pasting of double-sided adhesive on the non-release surface of a mold is a processing device used to accurately punch double-sided adhesive into the required shape and paste it onto the surface of a specific workpiece. It is usually used in industries such as electronics, automotive, and household appliances to achieve functions such as fixing, sealing, and buffering of components. The non-release surface includes other parts of the mold, such as the cavity wall, core, parting surface (except for the part used for release), guiding mechanism, ejection mechanism, etc. Although these parts do not directly participate in the release process of the product, they also play an important role in the overall structure of the mold, the molding process, and the quality of the product. For example, the cavity wall and core determine the shape and dimensional accuracy of the product, the guiding mechanism ensures the accuracy and stability of the mold opening and closing, and the ejection mechanism is used to eject the molded product from the mold.

[0003] After the punching work of the rolled double-sided adhesive is completed, when the punched double-sided adhesive is conveyed by a conveyor belt, some small double-sided adhesive fragments or debris will be generated during the punching process. They may adhere to the conveyor belt, especially when punching complex shapes or performing high-precision punching, more debris will be generated. Over time, it will gradually accumulate, making the surface of the conveyor belt sticky and affecting the normal operation and cleaning of the conveyor belt. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A punching and pasting process for double-sided adhesive on the non-release surface of a mold, including:

[0005] S1: Select a suitable double-sided adhesive material, and determine its thickness, adhesiveness, heat resistance performance indicators according to the usage requirements. Common double-sided adhesives include acrylate-based and rubber-based.

[0006] S2: Place the double-sided adhesive flat on the punching equipment, and pay attention to avoiding wrinkles on the double-sided adhesive.

[0007] S3: After positioning is completed, start the punching equipment, and the punching tool moves downward under pressure to punch the double-sided adhesive.

[0008] S4: After punching is completed, the subsequent mold moves upward with the punched double-sided adhesive, and at the same time, the double-sided adhesive is accurately pasted onto the surface of the workpiece through the pasting device. When pasting, it is necessary to ensure that the double-sided adhesive is in full contact with the surface of the workpiece to avoid bubbles and wrinkles.

[0009] The punching device includes a workbench. On both sides of the top of the workbench, auxiliary rollers are fixedly connected. On one side of the workbench, a feeding component is fixedly connected. On the side of the workbench away from the feeding component, a winding component is fixedly connected. On both sides of the workbench, collecting components are fixedly connected. Inside the workbench, a conveying component is fixedly connected;

[0010] A punching component, which is used for punching a roll of double-sided adhesive. The bottom of the punching component is fixedly connected to the middle of the top of the workbench;

[0011] The punching component includes a fixed rod and a lower cutting plate. The bottom of the fixed rod is fixedly connected to the top of the workbench. The top of the fixed rod is fixedly connected to a top plate. The top of the top plate is fixedly connected to an output mechanism. The side of the fixed rod is slidably connected to a moving plate. The top of the moving plate is fixedly connected to the output end of the output mechanism. The bottom of the moving plate is fixedly connected to an upper cutting block. The bottom of the lower cutting plate is fixedly connected to the middle of the top of the workbench;

[0012] By starting the output mechanism, through the output end of the output mechanism, the moving plate is driven to move downward on the fixed rod, so that the moving plate punches the double-sided adhesive passing through the lower cutting plate through the upper cutting block;

[0013] The conveying component includes a blanking port and a blanking plate. The blanking ports are symmetrically arranged inside the workbench. The side of the blanking plate is fixedly connected to the top inside the workbench. A driving mechanism is fixedly connected inside the blanking port. A conveyor belt is sleeved on the side of the driving mechanism. Through holes are evenly arranged on the side of the conveyor belt. A first suction machine is fixedly connected inside the workbench. The first suction machine is arranged inside the conveyor belt. A cleaning mechanism is fixedly connected to the bottom of the inner cavity of the workbench. The cleaning mechanism is arranged below the conveyor belt;

[0014] When cutting a roll of double-sided adhesive, by starting the first suction machine, through the suction generated when the first suction machine works, the double-sided adhesive that falls into the blanking plate through the punching component can fall and be adsorbed on the conveyor belt. By evenly arranging through holes on the conveyor belt, the double-sided adhesive cut by punching can be adsorbed on the conveyor belt for subsequent conveying work. The conveyor belt is driven to rotate by the driving mechanism, so as to convey the double-sided adhesive cut by punching;

[0015] By arranging a cleaning mechanism at the bottom of the conveyor belt, when the conveyor belt drives the double-sided adhesive cut by punching for conveying work, the side of the conveyor belt can be cleaned by the cleaning mechanism;

[0016] The cleaning mechanism includes a cleaning frame, both sides of which are fixedly connected to the inner side of the workbench. Both sides of the top of the cleaning frame are slidably connected with cleaning shafts. The top of the cleaning shafts is fixedly connected with cleaning plates. A first spring is sleeved on the cleaning shafts. The top of the first spring is fixedly connected to the bottom of the cleaning plate, and the bottom of the first spring is fixedly connected to the top of the cleaning frame. One side of the top of the cleaning plate is fixedly connected with a bent plate, and the other side of the top of the cleaning plate is rotatably connected with a cleaning roller.

[0017] When the driving mechanism drives the conveyor belt to rotate, the conveyor belt drives the double-sided tape cut off by punching to be conveyed. When the conveyor belt rotates, by contacting the conveyor belt with the bent plate, the bent plate cleans the side of the conveyor belt. At the same time, by arranging a cleaning roller on the other side of the bent plate, impurities on the side of the conveyor belt can be cleaned in time, reducing the wear of the conveyor belt by impurities.

[0018] At the same time, when the contact extrusion force between the bent plate and the impurities attached to the conveyor belt is greater than the tensile force of the first spring, the first spring contracts. At the same time, the first spring pulls the cleaning plate to move downward, so that the cleaning plate drives the bent plate to disengage from the conveyor belt, thus avoiding excessive contact extrusion force between the bent plate and the conveyor belt, which may cause scraping damage to the side of the conveyor belt.

[0019] Preferably, the collection component includes a collection housing, the side of which is fixedly connected to the inner side of the workbench. The bottom of the inner cavity of the collection housing is fixedly connected with a second suction machine. The top of the second suction machine is fixedly connected with a baffle. The top of the inner cavity of the collection housing is fixedly connected with a mesh plate. The top of the baffle is fixedly connected with a rotating mechanism.

[0020] When punching the rolled double-sided tape, by turning on the second suction machine and working with the suction force of the second suction machine, the impurities generated during punching are sucked into the inner cavity of the collection housing through the mesh plate for collection. At the same time, when the second suction machine is working with suction, the rotating mechanism can grab the flocculent dust that follows the processed impurities from the outside and enters the inner cavity of the collection housing.

[0021] Preferably, the rotating mechanism includes a fixed shaft, the bottom of which is fixedly connected to the top of the baffle. The number of fixed shafts is three. Rotating grooves are formed on the sides of the fixed shafts. The inner sides of the rotating grooves are rotatably connected with rotating plates. Grabbing grooves are formed on both sides of the rotating plates.

[0022] When working through the second suction machine, suction force is generated, causing the rotating plate to rotate in the rotating groove on the fixed shaft. At the same time, grasping grooves are provided on both sides of the rotating plate, so that when the rotating plate rotates, it can grasp the flocculent dust entering the inner cavity of the collection housing through the grasping grooves.

[0023] Preferably, the winding component includes a blanking frame, the side of the blanking frame is fixedly connected to the workbench, a winding drum is rotatably connected to the inner side of the blanking frame, connecting frames are fixedly connected to both sides of the blanking frame close to the winding drum, a motor is fixedly connected to the top of the connecting frame, a lead screw is rotatably connected to the inner side of the connecting frame, a slider is slidably connected to the inner side of the connecting frame, the inner side of the slider is threadedly connected to the side of the lead screw, the top of the lead screw is fixedly connected to the output end of the motor, and an extrusion mechanism is fixedly connected to the sides of the two sliders;

[0024] Start the drive motor on the winding drum to drive the winding drum to rotate. The rolled double-sided adhesive waste will be wound around the winding drum. During the winding process, by turning on the motor, the output end of the motor drives the lead screw to rotate on the connecting frame, so that the slider drives the extrusion mechanism to move upward, so that the extrusion mechanism extrudes the double-sided adhesive waste wound around the winding drum;

[0025] Preferably, the extrusion mechanism includes an extrusion frame, round blocks are fixedly connected to both sides of the extrusion frame, the side of the round block away from the extrusion frame is fixedly connected to the side of the slider, an extrusion shaft is slidably connected to the inner side of the extrusion frame, an extrusion rod is fixedly connected to the end of the extrusion shaft away from the extrusion frame, a second spring is sleeved on the extrusion shaft, one end of the second spring is fixedly connected to the extrusion rod, and the other end of the second spring is fixedly connected to the inner side of the extrusion frame;

[0026] When the winding drum winds the rolled double-sided adhesive waste, the slider drives the round block and the extrusion shaft to move upward, so that the extrusion shaft drives the extrusion rod to move towards the winding drum, so that when the rolled double-sided adhesive waste is wound and collected, the extrusion rod can extrude the waste on the winding drum. By extruding the waste on the winding drum with the extrusion rod, the rolled double-sided adhesive waste can be wound more tightly, improving the winding density. This helps to reduce the space occupied by the waste, enables the winding drum to accommodate more waste, reduces the frequency of replacing the winding drum, and improves work efficiency;

[0027] Meanwhile, when the extrusion force between the waste double-sided adhesive wound around the take-up reel and the extrusion rod is greater than the tensile force of the second spring, the second spring pulls the extrusion rod, and the extrusion rod moves through the extrusion axial extrusion frame, thus avoiding excessive extrusion force between the extrusion rod and the waste wound around the take-up reel, preventing damage to the wound waste double-sided adhesive and the take-up reel caused by excessive extrusion force, and preventing the waste from deforming and breaking due to excessive extrusion, which affects subsequent processing.

[0028] The present invention provides a die non-release surface double-sided adhesive punching and pasting process. It has the following beneficial effects:

[0029] 1. In this die non-release surface double-sided adhesive punching and pasting process, a cleaning mechanism is provided. The clean conveyor belt surface can better contact the double-sided adhesive, providing more stable friction force, ensuring that the double-sided adhesive will not slip or shift during transportation due to impurities on the conveyor belt surface, thereby improving the accuracy and efficiency of transportation, and ensuring that the double-sided adhesive after punching can be accurately transported to the next process for processing.

[0030] 2. In this die non-release surface double-sided adhesive punching and pasting process, a bent plate is provided. The bent plate cleans the side of the conveyor belt, which can remove the residual adhesive, dust or other impurities of the double-sided adhesive adhered to the conveyor belt, preventing these impurities from accumulating and affecting the normal operation and service life of the conveyor belt. The cleaning roller further cleans on the other side of the bent plate, which can clean the conveyor belt from different angles, enhance the cleaning effect, ensure the cleanliness of the conveyor belt surface, and avoid the transfer of impurities to the double-sided adhesive products in subsequent processing, ensuring product quality.

[0031] 3. In this die non-release surface double-sided adhesive punching and pasting process, a rotating mechanism is provided. The design of the grabbing groove can specifically grab flocculent dust. Compared with the simple suction collection method, this combined method of mechanical grabbing and suction can more effectively capture those flocculent dust that is not easily directly adsorbed by the air flow, improving the collection efficiency of specific types of impurities and further purifying the air environment in the collection housing.

[0032] 4. In this die non-release surface double-sided adhesive punching and pasting process, an extrusion mechanism is provided. During the winding process, the extrusion effect of the extrusion rod can prevent the wound waste double-sided adhesive from loosening or slipping on the take-up reel. Especially for some waste materials with soft texture or easy to deform, extrusion can keep them in a stable winding state, ensuring the winding quality and avoiding the situation of chaos or scattering of the waste materials during the collection process.

[0044] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] Please refer to Figure 1 , the present invention provides a technical solution: a die non-release surface double-sided adhesive punching and pasting process, including:

[0046] S1: Select a suitable double-sided adhesive material, and determine its thickness, viscosity, and temperature resistance performance indicators according to usage requirements. Common double-sided adhesives include acrylate and rubber types;

[0047] S2: Place the double-sided adhesive flat on the punching equipment, and pay attention to avoiding wrinkles on the double-sided adhesive;

[0048] S3: After positioning is completed, start the punching equipment. Under the action of pressure, the punching tool moves downward to punch the double-sided adhesive;

[0049] S4: After punching is completed, the subsequent die moves upward with the punched double-sided adhesive, and at the same time, the double-sided adhesive is accurately pasted onto the workpiece surface through the pasting device. When pasting, it is necessary to ensure that the double-sided adhesive is in full contact with the workpiece surface to avoid bubbles and wrinkles.

[0050] Please refer to Figures 1 - 3 , the present invention provides a technical solution: the punching equipment includes:

[0051] A workbench 1, both sides of the top of the workbench 1 are fixedly connected with auxiliary roller shafts 7, one side of the workbench 1 is fixedly connected with a feeding component 3, the side of the workbench 1 far from the feeding component 3 is fixedly connected with a winding component 4, both sides of the workbench 1 are fixedly connected with collecting components 5, and the inner side of the workbench 1 is fixedly connected with a conveying component 6;

[0052] A punching component 2, which is used for punching the rolled double-sided adhesive, and the bottom of the punching component 2 is fixedly connected with the middle of the top of the workbench 1;

[0053] Please refer to Figures 1 - 4 , the punching component 2 includes a fixed rod 21 and a lower cutting plate 26. The bottom of the fixed rod 21 is fixedly connected with the top of the workbench 1, the top of the fixed rod 21 is fixedly connected with a top plate 22, the top of the top plate 22 is fixedly connected with an output mechanism 23, the side of the fixed rod 21 is slidably connected with a moving plate 24, the top of the moving plate 24 is fixedly connected with the output end of the output mechanism 23, the bottom of the moving plate 24 is fixedly connected with an upper cutting block 25, and the bottom of the lower cutting plate 26 is fixedly connected with the middle of the top of the workbench 1;

[0054] By turning on the output mechanism 23, through the output end of the output mechanism 23, the moving plate 24 is driven to move downward on the fixed rod 21, so that the moving plate 24 punches the double-sided adhesive passing through the lower cutting plate 26 through the upper cutting block 25;

[0055] Please refer to Figures 1 - 5, the conveying component 6 includes a blanking port 61 and a blanking plate 62. The blanking port 61 is symmetrically opened on the inner side of the workbench 1. The side of the blanking plate 62 is fixedly connected to the top of the inner side of the workbench 1. A driving mechanism 63 is fixedly connected to the inner side of the blanking port 61. A conveyor belt 64 is sleeved on the side of the driving mechanism 63. Through holes 65 are evenly opened on the side of the conveyor belt 64. A first suction machine 66 is fixedly connected to the inner side of the workbench 1. The first suction machine 66 is arranged inside the conveyor belt 64. A cleaning mechanism 67 is fixedly connected to the bottom of the inner cavity of the workbench 1. The cleaning mechanism 67 is arranged below the conveyor belt 64;

[0056] When cutting the rolled double-sided tape, by turning on the first suction machine 66, due to the suction force generated during the operation of the first suction machine 66, the double-sided tape that falls into the blanking plate 62 through the punching component 2 can fall and be adsorbed on the conveyor belt 64. By evenly opening through holes 65 on the conveyor belt 64, the double-sided tape that is punched and dropped can be adsorbed on the conveyor belt 64 for subsequent conveying work. The driving mechanism 63 drives the conveyor belt 64 to rotate, thereby conveying the double-sided tape that is punched and dropped;

[0057] By arranging a cleaning mechanism 67 at the bottom of the conveyor belt 64, when the conveyor belt 64 drives the double-sided tape that is punched and dropped for conveying work, the cleaning mechanism 67 can clean the side of the conveyor belt 64;

[0058] Please refer to Figures 1 - 6 , the cleaning mechanism 67 includes a cleaning frame 671. Both sides of the cleaning frame 671 are fixedly connected to the inner side of the workbench 1. Cleaning shafts 672 are slidably connected to both sides of the top of the cleaning frame 671. A cleaning plate 673 is fixedly connected to the top of the cleaning shaft 672. A first spring 674 is sleeved on the cleaning shaft 672. The top of the first spring 674 is fixedly connected to the bottom of the cleaning plate 673. The bottom of the first spring 674 is fixedly connected to the top of the cleaning frame 671. A bent plate 676 is fixedly connected to one side of the top of the cleaning plate 673. A cleaning roller 675 is rotatably connected to the other side of the top of the cleaning plate 673;

[0059] When the driving mechanism 63 drives the conveyor belt 64 to rotate, the conveyor belt 64 drives the double-sided tape that is punched and dropped for conveying work. When the conveyor belt 64 rotates, by contacting the conveyor belt 64 with the bent plate 676, the bent plate 676 cleans the side of the conveyor belt 64. At the same time, by arranging a cleaning roller 675 on the other side of the bent plate 676, impurities on the side of the conveyor belt 64 can be cleaned in time, reducing the wear of the conveyor belt 64 by impurities;

[0060] Meanwhile, when the contact extrusion force between the bent plate 676 and the impurities attached to the conveyor belt 64 is greater than the tensile force of the first spring 674, the first spring 674 contracts. At the same time, the first spring 674 pulls the cleaning plate 673 downward to move, so that the cleaning plate 673 drives the bent plate 676 away from the conveyor belt 64, thus avoiding excessive contact extrusion force between the bent plate 676 and the conveyor belt 64, which may cause scraping damage to the side of the conveyor belt 64;

[0061] Cleaning is carried out in advance by the cleaning roller 675, which can prevent a large amount of impurities from accumulating at the contact between the bent plate 676 and the conveyor belt 64. This helps to avoid wear, deformation, etc. of the bent plate 676 due to long-term friction with impurities, thus protecting the cleaning function and structural integrity of the bent plate 676, reducing the maintenance and replacement frequency of the bent plate 676, and lowering the equipment maintenance cost;

[0062] Please refer to Figures 1 - 7 , the present invention provides a technical solution: the collection component 5 includes a collection housing 51, the side of the collection housing 51 is fixedly connected to the inner side of the workbench 1, the bottom of the inner cavity of the collection housing 51 is fixedly connected with a second suction machine 53, the top of the second suction machine 53 is fixedly connected with a baffle 54, the top of the inner cavity of the collection housing 51 is fixedly connected with a mesh plate 52, and the top of the baffle 54 is fixedly connected with a rotating mechanism 55;

[0063] When punching the rolled double-sided tape, by turning on the second suction machine 53 and working with the suction force of the second suction machine 53, the impurities generated during punching are sucked into the inner cavity of the collection housing 51 through the mesh plate 52 for collection. At the same time, when the second suction machine 53 is working for suction, the rotating mechanism 55 can grab the flocculent dust that follows the processed impurities outside and enters the inner cavity of the collection housing 51;

[0064] Please refer to Figures 1 - 8 , the rotating mechanism 55 includes a fixed shaft 551, the bottom of the fixed shaft 551 is fixedly connected to the top of the baffle 54, the number of the fixed shafts 551 is three, a rotating groove 552 is formed on the side of the fixed shaft 551, a rotating plate 553 is rotatably connected to the inner side of the rotating groove 552, and grabbing grooves 554 are formed on both sides of the rotating plate 553;

[0065] When the second suction machine 53 works, the generated suction force causes the rotating plate 553 to rotate in the rotating groove 552 on the fixed shaft 551. At the same time, since grabbing grooves 554 are formed on both sides of the rotating plate 553, when the rotating plate 553 rotates, it can grab the flocculent dust that enters the inner cavity of the collection housing 51 through the grabbing grooves 554;

[0066] Please refer to Figures 1 - 9, The present invention provides a technical solution: The winding component 4 includes a blanking frame 41. The side of the blanking frame 41 is fixedly connected to the workbench 1. A winding drum 42 is rotatably connected to the inner side of the blanking frame 41. Connecting frames 43 are fixedly connected to both sides of the blanking frame 41 close to the winding drum 42. A motor 44 is fixedly connected to the top of the connecting frame 43. A lead screw 45 is rotatably connected to the inner side of the connecting frame 43. A slider 46 is slidably connected to the inner side of the connecting frame 43. The inner side of the slider 46 is threadedly connected to the side of the lead screw 45. The top of the lead screw 45 is fixedly connected to the output end of the motor 44. An extrusion mechanism 47 is fixedly connected to the sides of the two sliders 46;

[0067] Start the drive motor on the winding drum 42 to drive the winding drum 42 to rotate. The rolled double-sided adhesive waste will be wound around the winding drum 42. During the winding process, by turning on the motor 44, the output end of the motor 44 drives the lead screw 45 to rotate on the connecting frame 43, so that the slider 46 drives the extrusion mechanism 47 to move upward, so that the extrusion mechanism 47 squeezes the double-sided adhesive waste wound around the winding drum 42;

[0068] Please refer to Figures 1 - 10 , The extrusion mechanism 47 includes an extrusion frame 471. Circular blocks 472 are fixedly connected to both sides of the extrusion frame 471. The side of the circular block 472 away from the extrusion frame 471 is fixedly connected to the side of the slider 46. An extrusion shaft 473 is slidably connected to the inner side of the extrusion frame 471. One end of the extrusion shaft 473 away from the extrusion frame 471 is fixedly connected to an extrusion rod 475. A second spring 474 is sleeved on the extrusion shaft 473. One end of the second spring 474 is fixedly connected to the extrusion rod 475. The other end of the second spring 474 is fixedly connected to the inner side of the extrusion frame 471;

[0069] When the winding drum 42 winds the rolled double-sided adhesive waste, the slider 46 drives the circular block 472 and the extrusion shaft 473 to move upward, so that the extrusion shaft 473 drives the extrusion rod 475 to move towards the winding drum 42. When the rolled double-sided adhesive waste is wound and collected, the extrusion rod 475 can squeeze the waste on the winding drum 42. By squeezing the waste on the winding drum 42 with the extrusion rod 475, the rolled double-sided adhesive waste can be wound more tightly, improving the winding density. This helps to reduce the space occupied by the waste, enables the winding drum 42 to accommodate more waste, reduces the frequency of replacing the winding drum 42, and improves work efficiency;

[0070] Meanwhile, when the extrusion force between the waste double-sided adhesive wound around the take-up reel 42 and the extrusion rod 475 is greater than the tensile force of the second spring 474, the second spring 474 pulls the extrusion rod 475 to move towards the extrusion frame 471 through the extrusion shaft 473, thus avoiding excessive extrusion force between the extrusion rod 475 and the waste material wound around the take-up reel 42, preventing damage to the wound waste double-sided adhesive and the take-up reel 42 caused by excessive extrusion force, and preventing the waste material from deforming and breaking due to excessive extrusion, which affects subsequent processing;

[0071] Uniform extrusion can make the waste material distribute more evenly on the take-up reel 42, avoiding uneven pressure on the take-up reel 42 caused by excessive accumulation of local waste material, thus prolonging the service life of the take-up reel 42 and reducing the maintenance and replacement costs of the equipment;

[0072] Specific working process:

[0073] After starting the feeding component 3, the driving mechanism 63 of the feeding component 3 consists of a motor, a reducer, a transmission gear and a feeding roller. The motor transmits power to the transmission gear through the reducer, drives the feeding roller to be in direct contact with the double-sided adhesive, and drives the double-sided adhesive to be conveyed forward through friction, passing through the auxiliary roller shaft 7 and entering the punching component 2. During the feeding process, a positioning sensor will be set to accurately control the feeding length and position of the double-sided adhesive;

[0074] By starting the punching component 2, the punching work is carried out on the wound double-sided adhesive passing through the punching component 2. At the same time, by starting the collecting component 5, the debris generated during the punching work is collected, and the cut-off double-sided adhesive is conveyed and discharged through the conveying component 6;

[0075] During the punching process of the double-sided adhesive, some waste materials will be generated, such as the excess part cut off. The starting end of the waste double-sided adhesive roll is fixed on the winding component 4 through the auxiliary roller shaft 7. The feeding component 3 and the waste winding component 4 run synchronously through the control system, and the feeding speed of the feeding component 3 and the winding speed of the winding component 4 maintain a certain proportional relationship to ensure that the waste material can be wound up in a timely and smooth manner.

[0076] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative work shall fall within the protection scope of the present invention.
