Abstract

This invention discloses a die-cutting device and its method for producing diffuser sheets, belonging to the field of diffuser sheet production and processing. It includes a frame and a die-cutting table. A first transition table and a second transition table are respectively arranged on both sides of the outer surface of the die-cutting table. A feeding mechanism for conveying the diffuser sheets to be processed is arranged in the middle of the upper surface of the first transition table. A leveling mechanism to prevent warping of the cut diffuser sheets is arranged in the middle of the surface of the second transition table. The leveling mechanism includes a pressure roller assembly arranged in the middle of the outer circular surfaces of the first and second rotating rods. This application addresses diffuser sheets with inconsistent thicknesses by using a tightening mechanism to tighten the tightening cloth, thereby changing the compression length of the spring coil, causing the pressure roller to move inward, compressing the diffuser sheet and completing the leveling operation.

Description

Technical Field

[0001] The present invention relates to the field of production and processing of diffusion sheets, and more specifically, to a die-cutting device for production and processing of diffusion sheets and a method for using the same. Background Art

[0002] In the process of cutting the diffuser using a die-cutting machine, since the diffuser material itself has a certain toughness, the cut end is very likely to have a warping problem during the actual operation.

[0003] The traditional solution in the prior art is generally to perform secondary flattening on the warped end through an external pressure roller. However, during the extrusion molding or coating process, if the flow rate is unstable, the temperature is improperly controlled, or the coating head is blocked, etc., the thickness of the diffuser may be inconsistent. When flattening diffusers of different thicknesses, in order to make the extruded end fit more closely, it is necessary to manually replace the pressure roller of the corresponding size to complete the flattening process. However, this method is not only cumbersome to operate and requires a lot of manpower, but also inefficient and difficult to meet the needs of large-scale production. Summary of the invention

[0018] S2: After the diffusion layer is prepared, the diffusion sheet is placed in a high-temperature furnace for sintering.

[0022] (1) This solution is provided with a leveling mechanism and a tightening mechanism to transport the cut diffuser to the second transition table. When the diffuser approaches the bottom of the first rotating rod, the second servo motor is started to use the pressure roller to straighten the edge of the diffuser. For diffusers with inconsistent thickness, the tightening cloth can be tightened by the tightening mechanism to change the compression length of the spring coil, so that the pressure roller moves inward, and then the pressure roller squeezes the diffuser and completes the warping operation. Compared with the traditional manual replacement of the corresponding size pressure roller to complete the leveling operation, this operation method is simpler and faster, does not require a lot of manpower, and can meet the needs of large-scale production.

[0023] (2) By providing a material collection mechanism, during the cutting process, in order to reduce the impact of waste materials on the diffuser and the workload of subsequent processing, when the cut diffuser is trimmed by the pressure roller assembly, part of the waste materials is first guided through the pressure roller assembly and reversely wound on the take-up drum. Subsequently, the third servo motor is started to drive the take-up rod to rotate clockwise, thereby driving the take-up drum to rotate synchronously clockwise. The rotational force of the take-up drum is utilized to collect the waste materials continuously generated during the cutting process, thereby effectively avoiding the waste materials from directly adhering to the diffuser, thereby reducing the workload of subsequent manual picking and screening of the diffuser.

[0024] (3) By providing an auxiliary support assembly, after the waste is rolled up on the winding drum, more and more waste is wound around the outside of the winding drum, which leads to a decrease in the winding efficiency. Therefore, when the waste wound around the outside of the winding drum reaches a certain amount and affects the winding efficiency, the cutting work is stopped, the locking elements on the winding drum are unlocked and removed in turn, the old winding drum is removed from the winding rod, and a new winding drum is replaced to ensure that the subsequent waste treatment work can be carried out continuously and efficiently.

[0048] See also Figures 1 to 10A die-cutting device for producing and processing a diffuser sheet comprises a frame 1, a die-cutting table 2 is arranged on the upper surface of the frame 1, lifting cylinders 3 are installed at the four corners inside the die-cutting table 2, the die-cutting table 2 is fixedly connected with a die-cutting assembly 4 through the lifting cylinders 3, a first transition table 6 and a second transition table 7 are arranged on both sides of the outer surface of the die-cutting table 2, a feeding mechanism 9 for conveying a diffuser sheet to be processed is arranged in the middle of the upper surface of the first transition table 6, a leveling mechanism 11 for preventing the diffuser sheet from warping after cutting is arranged in the middle of the surface of the second transition table 7, the leveling mechanism 11 comprises a first rotating rod 112 and a second rotating rod 113 arranged on the upper surface of the second transition table 7, and a pressing roller assembly 114 for leveling the warped diffuser sheet is arranged in the middle of the outer circumference of the first rotating rod 112 and the second rotating rod 113;

[0049] The pressure roller assembly 114 includes a spring ring 1141 fixedly connected to the first rotating rod 112 and the second rotating rod 113, one end of the spring ring 1141 is fixedly connected to a pressure roller 1142, the outer circumferential surface of the pressure roller 1142 is wrapped with a tightening cloth 1143, and the first rotating rod 112 and the second rotating rod 113 are also provided with a tightening mechanism 14 for tightening the tightening cloth 1143; and the tightening mechanism 14 is used in conjunction with the tightening cloth 1143, so that the pressure roller 1442 performs edge trimming on diffusers of different thicknesses, and the tightening mechanism 14 includes a fourth servo motor 141 fixedly connected to one end of the outer circumferential surface of the first rotating rod 112, and a fourth servo motor 141 is fixedly connected to one end of the outer circumferential surface of the first rotating rod 112. The output end of the servo motor 141 is fixedly connected to the first tightening rod 142, the outer circumferential surface of the first tightening rod 142 is fixedly connected to the first gear 143, the outer surface of the first gear 143 is meshingly connected to the second gear 146, the interior of the second gear 146 is fixedly connected to the second tightening rod 145, both ends of the second tightening rod 145 are provided with a support seat 144 fixedly connected to the first rotating rod 112, the outer side of the fourth servo motor 141 is provided with an electric telescopic rod 147 fixedly connected to the first rotating rod 112, the top of the electric telescopic rod 147 is fixedly connected to a horizontal plate 148, and one side of the horizontal plate 148 is fixedly connected to a locking frame 149.

[0050] like Figure 7 , Figure 8 , Fig. 9As shown, both ends of the first rotating rod 112 and the second rotating rod 113 are fixedly connected with the first shielding cover 1144 and the second shielding cover 1145, and one end of the first rotating rod 112 and the second rotating rod 113 is jointly provided with a driving assembly for transmission, and the driving assembly includes a second servo motor 115 for driving the first rotating rod 112; and the first rotating rod 112 is fixedly connected with a first fixed wheel 116 on one side close to the second servo motor 115, and the second rotating rod 113 is fixedly connected with a second fixed wheel 117 on one side close to the second servo motor 115, and the outer surfaces of the first fixed wheel 116 and the second fixed wheel 117 are jointly sleeved with a transmission belt 118, and the four corners of the die-cutting table 2 are all threadedly connected with a triangular plate 5 The first transition platform 6 and the second transition platform 7 are fixedly connected to the die-cutting table 2 through the triangular plate 5; and the four corners of the die-cutting table 2 are fixedly connected with triangular support blocks 21 for supporting the first transition platform 6 and the second transition platform 7, and the upper surface of the second transition platform 7 is fixedly connected with a second support block 111 for supporting the first rotating rod 112 and the second rotating rod 113; and the first rotating rod 112 and the second rotating rod 113 are both rotatably connected in the second support block 111, and one side of the upper surface of the second transition platform 7 is fixedly connected with a connecting rod 119, and the bottom end of the connecting rod 119 is fixedly connected with a connecting plate 1110, and both sides of the connecting plate 1110 are fixedly connected with wiping cotton plates 1111 for cleaning the tightening cloth 1143.

[0051] Place the entire frame 1 stably on the ground, and firmly connect the first transition platform 6 and the second transition platform 7 to both sides of the die-cutting table 2 through bolts and triangular plates 5, so as to expand the workbench area and facilitate cutting operations. When fixing the extension table, use the triangular support block 21 to provide auxiliary support to enhance the stability of the structure. After installation, place the diffuser to be cut on the die-cutting table 2, start the lifting cylinder 3, drive the die-cutting assembly 4 to descend and accurately cut the diffuser. After cutting, transport the diffuser to the second transition platform 7. When the diffuser approaches the bottom of the first rotating rod 112, start the second servo motor 115 to drive the first rotating rod 112 and the first fixed wheel thereon. 116 rotates clockwise, and through the linkage effect of the transmission belt 118, the second fixed wheel 117 drives the second rotating rod 113 to rotate synchronously clockwise in the second supporting block 111, so that both the two pressing roller assemblies 114 rotate clockwise, and the pressing roller assembly 114 is used to perform edge trimming on the edge of the diffuser, flatten the raised part, improve the overall flatness of the diffuser, and ensure the quality of the finished product. However, when a diffuser with inconsistent thickness needs to be trimmed, the electric telescopic rod 147 can be started first, which is in a retracted state, so that the horizontal plate 148 drives the locking frame 149 to move downward, and then the fourth servo motor 141 is started to rotate forward, so that the first tightening rod 1 42 drives the first gear 143 to rotate clockwise, so that the meshing second gear 144 drives the second tightening rod 145 to rotate counterclockwise, and then both ends of the tightening cloth 1143 pass through the interior of the locking frame 149, and the two ends are respectively wound around the first tightening rod 142 and the second tightening rod 145, and in the process of tightening, the spring ring 1141 is compressed, and in this process, the pressure rollers 1142 evenly distributed around the first rotating rod 112 are all close to the first rotating rod 112, so that the outer diameter formed by the multiple pressure rollers 1442 is reduced, and then the pressure rollers 1442 adapt to the thicker diffusion sheet and squeeze the thicker diffusion sheet. The leveling operation is completed. Compared with the traditional method of manually replacing the corresponding size of pressure rollers to complete the leveling operation, this edge-leveling operation is simpler and faster, does not require a lot of manpower, and can meet the needs of large-scale production. In the edge-leveling process, the wiping cotton plate 1111 is used to regularly wipe the surface of the tightening cloth 1143 to keep it clean and dust-free, to prevent dust particles from contaminating the surface of the tightening cloth 1143 and leaving spots on the surface of the diffuser, affecting the use effect of the final product. Through the above process, not only the work efficiency is improved, but also the scrap rate and cost burden in the production process are significantly reduced, ensuring the accuracy of cutting and edge-leveling operations and the quality of finished products.

[0052] like Figure 1 , Figure 5 , Figure 7As shown, a material receiving mechanism 12 for collecting waste is provided on one side of the second transition platform 7 close to the die-cutting table 2, and the material receiving mechanism 12 includes a support 121 fixedly connected to the lower right corner of the second transition platform 7, and a third servo motor 122 is fixedly connected to the outer side of the top of the support 121, and the output end of the third servo motor 122 passes through the support 121 and is fixedly connected to a winding rod 123, and a winding drum 126 for winding up the waste is sleeved in the middle of the outer cylindrical surface of the winding rod 123.

[0053] During the cutting process, in order to reduce the impact of waste on the diffuser and the workload of subsequent processing, when the cut diffuser is trimmed using the pressure roller 1442, part of the waste is first guided through the pressure roller 1442 and reversely wound around the take-up drum 126. Subsequently, the third servo motor 122 is started to drive the take-up rod 123 to rotate clockwise, thereby driving the take-up drum 126 to rotate synchronously clockwise. The rotational force of the take-up drum 126 is utilized to collect the waste continuously generated during the cutting process, thereby effectively preventing the waste from directly adhering to the diffuser. The above method can not only maintain the cleanliness and overall aesthetics of the diffuser, but also significantly reduce the workload of subsequent manual picking and screening of the diffuser, thereby improving the efficiency and automation level of the entire cutting workflow.

[0054] like Figure 1 , Figure 5 , Figure 7 As shown, the first limit plate 124 and the second limit plate 127 are fixedly connected to the winding rod 123 and the winding drum 126 on one side close to the support 121, and the first locking hole 125 and the second locking hole 128 are opened on the other side of the outer circumferential surface of the winding rod 123 and the winding drum 126, and an auxiliary support assembly 129 for supporting the winding rod 123 is arranged at the upper right corner of the second transition platform 7.

[0055] like Figure 2 , Figure 5 , Figure 7 As shown, the auxiliary support assembly 129 includes a supporting plate 1291 fixedly connected to the upper right corner of the second transition platform 7, and a bracket 1292 is hinged on the top of the supporting plate 1291; and the middle of the top of the bracket 1292 is an arc-shaped depression, and the inner side of the bottom end of the bracket 1292 is fixedly connected to the first clamping block 1293, and the inner side of the top end of the supporting plate 1291 is fixedly connected to the second clamping block 1294.

[0056] After the waste is rolled up on the take-up drum 126, more and more waste is wrapped around the outside of the take-up drum 126, resulting in a decrease in the winding efficiency. Therefore, it is necessary to regularly replace a new take-up drum 126 to ensure that the waste processing work can proceed normally. At this time, when the take-up drum 126 is wrapped with a certain amount of waste, affecting the winding effect, first stop the cutting work, take out the bolts locked by the first clamping block 1293 and the second clamping block 1294, and then hold the handle and rotate the bracket 1292 counterclockwise to make one end of the winding rod 123 in a suspended state, and respectively take out the locking bolts located in the first locking hole 125 and the second locking hole 128, as well as the locking bolts inside the first limit plate 124 and the second limit plate 127. After removing all the locking elements, the old take-up drum 126 can be easily removed from the winding rod 123 and replaced with a new take-up drum 126, ensuring that the subsequent waste processing work can be carried out continuously and efficiently.

[0057] like Figure 1 , Figure 2 , Figure 5 As shown, the feeding mechanism 9 includes a first driving rod 92 and a second driving rod 93 which are arranged on the upper surface of the first transition platform 6. The outer circumferential surfaces of the first driving rod 92 and the second driving rod 93 are fixedly connected with evenly distributed rollers 94. The upper surface of the first transition platform 6 is fixedly connected with a first supporting block 91 for supporting the first driving rod 92 and the second driving rod 93. The first driving rod 92 passes through the first supporting block 91 and is fixedly connected with a first servo motor 95. A transmission assembly 96 is commonly arranged between the first driving rod 92 and the second driving rod 93.

[0058] The diffuser to be processed is placed on the first transition table 6, and the diffuser is initially fixed by means of the roller 94 installed on the first transition table 6 and guided by the first driving rod 92 to ensure that it maintains a relatively stable position in subsequent operations. Then, the first servo motor 95 is started, and the motor serves as a power source to drive the entire conveying and fixing system to start working. At the same time, the second driving rod 93 is driven to rotate by the transmission component 96 (including a first pulley fixed at one end of the first driving rod 92 and a second pulley fixed at one end of the second driving rod 93, and the two pulleys are connected by a belt). As the first driving rod 92 and the second driving rod 93 rotate, the rollers 94 on each of them also start to roll. In this process, the rolling of the rollers 94 not only further enhances the fixing effect of the diffuser, but also utilizes its friction or guiding mechanism to automatically and smoothly transport the diffuser to the cutting area of ​​the die-cutting table 2. Through the above process, not only the operating efficiency is improved, but also the stability and accuracy of the diffuser before cutting are ensured, laying a solid foundation for subsequent high-precision cutting operations.

[0059] like Figure 3 , Figure 4As shown, both sides of the upper surface of the die-cutting table 2 are provided with a guide mechanism 8 for preventing the diffusion sheet from deviating, and the guide mechanism 8 includes support plates 81 fixedly connected to both sides of the upper surface of the die-cutting table 2; and a fixing rod 82 and a support rod 83 are fixedly connected in the middle of adjacent support plates 81, and the support rod 83 is provided with evenly distributed limiting holes 84 inside, and the outer surfaces of the fixing rod 82 and the support rod 83 are respectively slidably connected with a baffle plate 85 and a sliding sleeve 87, and a connecting seat 86 is commonly connected between the baffle plate 85 and the sliding sleeve 87.

[0060] In order to ensure that the diffuser to be processed can maintain a stable motion trajectory when it is conveyed to the cutting area and avoid the problem of uneven cutting caused by deviation, first, according to the size and conveying requirements of the diffuser to be processed, the sliding sleeve 87 is toggled to slide on the support rod 83, and the connecting seat 86 is used to drive the baffle 85 to slide synchronously on the fixed rod 82. When the distance between the two baffles 85 is adjusted to a suitable position, which can ensure that the diffuser to be processed will not have a large deviation during the movement, the locking bolt is used to pass through the limiting hole 84 to fix the sliding sleeve 87, and then the diffuser to be processed is moved along the preset trajectory by the roller 94. It can smoothly enter the cutting area. At the same time, by observing the scale added on the support rod 83, the operator can adjust the position of the baffle 85 more accurately, reduce the adjustment time and error, and add a buffer pad on the surface where the baffle 85 contacts the diffusion sheet to be processed to reduce friction and scratches and protect the surface quality of the diffusion sheet. Through an external automatic detection system, the movement trajectory and position of the diffusion sheet are monitored in real time. Once a deviation is found, an alarm is immediately issued and automatic adjustments are made, thereby further improving the stability and reliability of the conveying system, ensuring that the diffusion sheet to be processed can enter the cutting area accurately and efficiently, and improving product quality and production efficiency.

[0061] like Figure 2 , Figure 6 As shown, a propulsion assembly 10 is arranged in the middle of the guide mechanism 8 and the die-cutting assembly 4. The propulsion assembly 10 includes movable grooves 101 opened on both sides of the die-cutting table 2. The interior of the movable grooves 101 is rotatably connected with an axle rod 103. The outer cylindrical surface of the axle rod 103 is fixedly connected with a roller 104 for propelling the movement of the diffuser. One end of the axle rod 103 passes through the movable groove 101 and is fixedly connected with a driving motor 102.

[0062] like Figure 1 , Figure 3 , Fig.10 As shown, a conveying assembly 13 for conveying the finished diffuser is provided on the outer side of the second transition platform 7, and the conveying assembly 13 includes a support arm 131 fixedly connected to the two ends of the outer side of the second transition platform 7, and a transition plate 133 is fixedly connected to the middle of the support arm 131. Correction assemblies 134 are provided on both sides of the transition plate 133, and a transparent cover plate 132 is fixedly connected to the upper surface of the support arm 131.

[0063] When the diffuser to be processed needs to be transported to the die-cutting table 2 for cutting, the driving motor 102 located on the right side of the die-cutting table 2 is first started to drive the shaft 103 to rotate, thereby driving the roller 104 to roll in the movable groove 101, and the rotation of the roller 104 provides a smooth conveying path for the diffuser, which is smoothly pushed from the input end to the cutting area of ​​the die-cutting table 2. When the diffuser reaches the cutting area, the predetermined cutting operation is performed. After the cutting is completed, the driving motor 102 on the left side of the die-cutting table 2 is started, and the rotation of the shaft 103 and the roller 104 is used again to transport the cut diffuser from the cutting area to the second transition table 7. On the second transition table 7, the diffuser after cutting is The diffuser is further adjusted by the correction component 134, the structure of which is similar to the guide mechanism 8, to ensure that the direction and position of the diffuser are accurate. Subsequently, the diffuser slides off the transition plate 133 under the guidance, and finally falls into the collection box to be collected. During the entire transportation process, the design of the transparent cover 132 allows the operator to check the transportation status at any time to ensure that the diffuser moves smoothly without jamming or offset. If any abnormality is found, the operator can take corresponding measures to make adjustments in time to ensure production efficiency and product quality. Through the above process, the equipment realizes fully automated processing of the diffuser to be processed from input to output, which significantly improves production efficiency and operational convenience.

[0064] A method for using an automated production device for a diffuser sheet comprises the following steps:

[0065] S1: First, silicon is extracted from silicon ore, and high-purity silicon wafers are obtained through refining and purification. The silicon wafers are then purified, and then diffusion sources are coated on the clean silicon wafers under high temperature reaction to prepare the diffusion layer;

[0066] S2: After the diffusion layer is prepared, the diffusion sheet is placed in a high-temperature furnace for sintering. After the sintering is completed, the cooled diffusion sheet is placed on the die-cutting table 2 through a conveying device, and is cut using a die-cutting assembly 4 according to actual needs;

[0067] S3: After the cutting is completed, the diffusion sheet is transported to the second transition stage 7, and the fourth servo motor 141 is started to make the pressure roller 1142 perform edge trimming operation on the cut diffusion sheet, and the third servo motor 122 is started at the same time, and the waste is collected by the winding drum 126;

[0068] S4: Finally, the cut diffusion sheet is transported to an external inspection platform by using the transport assembly 13 to complete the final test and packaging.

[0069] Working principle: Place the entire frame 1 stably on the ground, and firmly connect the first transition platform 6 and the second transition platform 7 to both sides of the die-cutting table 2 through bolts and triangular plates 5 to expand the workbench area and facilitate cutting operations. When fixing the extension table, use the triangular support block 21 to provide auxiliary support to enhance the stability of the structure. After the installation is completed, place the diffuser to be processed on the first transition platform 6, and use the synergistic effect of the roller 94 and the first drive rod 92 and the second drive rod 93 installed on the first transition platform 6 to drive the diffuser through the first servo motor 95 to perform preliminary fixation and transportation of the diffuser. According to the cutting requirements, adjust the guide mechanism 8 such as the sleeve 87, the baffle 85, etc. to ensure that the diffuser maintains a stable motion trajectory during the transportation process, and then push the diffuser to be cut to the cutting area of ​​the die-cutting table 2 through the propulsion assembly 10. When the diffuser reaches the cutting area, start the lifting. The cylinder 3 uses the die-cutting component 4 to cut the diffuser. When the cutting is completed, the left part of the propulsion component 10 is continued to be used to transport the cut diffuser from the cutting area to the second transition table 7. When the diffuser approaches the bottom of the first rotating rod 112, the second servo motor 115 is started to drive the first rotating rod 112 and the first fixed wheel 116 thereon to rotate clockwise. Through the linkage action of the transmission belt 118, the second fixed wheel 117 drives the second rotating rod 113 to rotate synchronously clockwise in the second supporting block 111, and the edge of the diffuser is leveled by the pressure roller 1442. During the edge leveling process, the wiping cotton plate 1111 regularly wipes the surface of the tightening cloth 1143 to keep it clean and dust-free, and prevent spots on the surface of the diffuser due to dust particles on the surface of the tightening cloth 1143. At the same time, part of the waste is guided through the pressure roller 1442 and reversely wound on the winding drum 126. The third servo motor 122 is started to drive the winding rod 123 to rotate clockwise, thereby driving the winding drum 126 to rotate clockwise synchronously, so as to collect the waste continuously generated during the cutting process and complete the edge-aligned diffusion sheet. After adjustment by the correction component 134, it slides from the transition plate 133 into the collection box to complete the collection.

[0070] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
