[0002] Mylar, also known as polyester film or Mylar, is a film material made of polyester resin. Due to its good insulation and high temperature resistance, Mylar is often used as the insulation layer of wires and cables, as well as the isolation material between electronic components. At the same time, it is also used to make the support and isolation structures of electronic components such as capacitors, resistors, and inductors, which can ensure the safe operation of equipment in high-voltage and high-temperature environments.
[0003] As an insulating material, the bent Mylar sheet can more flexibly adapt to the complex layout inside electronic devices, effectively isolate different electronic components, prevent short circuits between components on the circuit board, and thus ensure the safe operation of electronic devices. The bent Mylar sheet can provide more stable mechanical support, help fix electronic components, and prevent them from moving or being damaged when subjected to external impacts inside the device.
[0004] However, in the bending and blanking process of Mylar sheets, in order to ensure the blanking efficiency, the Mylar sheets are bent with high strength during the bending process, and are bent with great force during the blanking process after the Mylar sheets are bent, resulting in uneven stress distribution inside the Mylar sheets, and making it easy for the Mylar sheets to break during the bending and blanking process.

[0018] To achieve the above object, the second technical solution adopted by the present invention is: a processing technology of a continuous mylar processing device, including the following steps:

[0025] The present invention solves the defects existing in the background technology, and the present invention has the following beneficial effects:
[0026] (1) The present invention provides a continuous mylar processing device. By using components such as a pushing unit, a deformation unit, a die, and a conveying unit, the pushing unit pushes the mylar sheet to move, enabling the mylar sheet to pass through the primary rollers and the secondary rollers in sequence, and finally reaching the mylar groove for bending and then being die-cut by the die. Compared with the mylar processing devices in the prior art, it can provide a supporting force for the bending and die-cutting processes of the mylar sheet, avoid uneven stress during the bending and die-cutting processes, and solve the defect of fracture due to uneven stress during the bending and blanking processes of the mylar sheet in the prior art.
[0027] (2)In the present invention, the springs of the secondary elastic structure are fixedly connected to the deformation base block and hinge-connected to the secondary rollers respectively. The hinge connection direction between the secondary elastic structure and the secondary rollers is perpendicular to the acting direction of the secondary elastic structure. Compared with the prior art, the elastic structure perpendicular to the groove surface can provide effective supporting force for the secondary rollers, ensure their stability during the processing, and can reduce the springback phenomenon of the mylar sheet after bending, thereby improving the final precision of the product.
[0028] (3)In the present invention, in the cross-section of the secondary roller groove, the groove opening size at the intersection with the deformation base block is smaller than the diameter size of the secondary roller. The smaller groove opening size limits the movement range of the secondary rollers. Compared with the prior art, it can adjust the pressure of the secondary rollers on the mylar sheet, ensure the stress average on the side surface, and can ensure the precise action of the secondary rollers on the mylar sheet, thereby improving the accuracy during the processing.
[0029] (4)In the present invention, a plurality of positioning columns are fixedly arranged on one of the primary rollers. The plurality of positioning columns are respectively arranged on the upper surface of the primary roller. The positioning columns are used to combine with the positioning holes on the mylar sheet to determine the orientation of the mylar sheet. Compared with the prior art, it can prevent the mylar sheet from shifting during the processing, and keep the mylar sheet firmly attached to the primary roller, ensuring that the mylar sheet can be closely attached to the pushing block and the mylar groove respectively during the processing, and ensuring the accuracy and stress uniformity during the processing.
[0030] (5)In the present invention, the pushing block is located directly above the mylar groove and the cross-section of the pushing block matches the cross-section of the mylar groove. The matching of the cross-section of the pushing block and the cross-section of the mylar groove ensures that the mylar sheet can be accurately aligned with the groove position during the pushing process. Compared with the prior art, it can reduce errors and apply force to the mylar sheet more evenly, reduce local stress concentration, and ensure the stability during the processing.
[0031] (6)In the present invention, when the mylar sheet is placed on a plurality of primary rollers, one surface of each secondary roller is horizontally arranged, and the horizontally arranged surfaces of the plurality of secondary rollers are located on the same horizontal plane. Ensuring that all secondary rollers are on the same horizontal plane helps to apply uniform force to the mylar sheet. Compared with the prior art, it can achieve uniform bending, avoid local stress concentration, and the unified horizontal plane setting helps to improve the bending accuracy, ensuring that the bending angles and shapes of each mylar sheet are consistent.

[0037] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0038] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.
[0039] In the description of the present application, it should be understood that the orientation or positional relationships indicated by the terms "center", "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the protection scope of the present application. In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.
[0040] In the description of this application, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "linkage" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0041] The mylar sheet in this application is a non-metallic mylar sheet and has a processing requirement of a certain bending angle. A long strip of mylar sheet blank can be divided into several mylar sheets of the same specification by punching. There are several positioning holes on the mylar sheet, and the areas of each mylar sheet are divided on the mylar sheet blank through the positioning holes.
[0042] Such as Figure 1 and Figure 2 As shown in, a continuous mylar processing device includes: a frame 100, and a pushing unit 200 and a deformation unit 300 respectively and fixedly arranged on the frame 100.
[0043] The pushing unit 200 is located above the deformation unit 300, and the pushing unit 200 is used to push the mylar sheet downward. The pushing unit 200 includes: a pushing block 210, a pushing support rod 220 fixedly connected to the pushing block 210, and a cylinder 230 fixedly connected to the pushing support rod 220; the centroids of the pushing block 210, the pushing support rod 220, and the cylinder 230 are located on the same vertical line, and the cylinder 230 drives the pushing support rod 220 to move vertically downward.
[0044] The alignment of the centroids ensures that the force generated by the cylinder 230 can be directly and losslessly transmitted to the pushing support rod 220 and the pushing block 210, improving the force transmission efficiency. When the centroids are aligned, the torque generated due to eccentricity can be reduced, thereby reducing the vibration and noise of the structure and improving the stability of the device. The centroid configuration on the vertical line helps to enhance the rigidity of the overall structure and reduce bending or deformation during the pushing process.
[0045] The pushing block 210 is located directly above the mylar groove and the cross-section of the pushing block 210 matches the cross-section of the mylar groove. The matching of the cross-section of the pushing block 210 and the cross-section of the mylar groove ensures that the mylar sheet can be accurately aligned with the groove during the pushing process, reducing errors. When the cross-section of the pushing block 210 matches the cross-section of the mylar groove, the force can be applied to the mylar sheet more evenly, reducing local stress concentration and avoiding material damage. The bottom end of the pushing block 210 is chamfered or rounded. The chamfer or round corner can reduce the stress concentration at the bottom end of the pushing block and avoid material fatigue or fracture caused by excessive stress. The smooth rounding treatment can prevent scratching or damaging the surface of the mylar sheet during the pushing process and maintain the appearance quality of the product.
[0046] As shown Figure 3 in the figure, the deformation unit 300 includes: a deformation base block 310, and a plurality of primary rollers 320 and a plurality of secondary rollers 330 respectively arranged on the deformation base block 310; the deformation base block 310 is fixedly connected to the frame 100, and a plurality of primary roller grooves and a plurality of secondary roller grooves are respectively arranged on the deformation base block 310. The number of the plurality of primary roller grooves is the same as and corresponds one by one to the number of the plurality of primary rollers 320, and the number of the plurality of secondary roller grooves is the same as and corresponds one by one to the number of the plurality of secondary rollers 330. The plurality of primary rollers 320 are respectively rotatably connected to the deformation base block 310. The plurality of primary rollers 320 are located on the same horizontal plane, the plurality of secondary rollers 330 are located on the same horizontal plane, the primary rollers 320 are located above the secondary rollers 330. A mylar groove is arranged on the deformation base block 310, and the mylar groove is arranged between adjacent primary rollers 320 and between adjacent secondary rollers 330. The plurality of primary rollers 320 and the plurality of secondary rollers 330 respectively intersect with the groove surface of the mylar groove, and the cross-section of the mylar groove is V-shaped.
[0047] Through the staged arrangement of the primary rollers and the secondary rollers, the mylar sheet can gradually enter the mylar groove, realizing a more stable and controlled deformation process. The intersecting design of the rollers and the mylar groove helps to accurately position the mylar sheet during the bending process, ensuring the bending accuracy. The contact between the rollers and the groove surface helps to evenly distribute the stress on the mylar sheet during the bending process, reducing local deformation or damage of the material. The gradual deformation guidance helps to reduce the springback phenomenon of the material after bending, ensuring the accuracy of the bending angle.
[0048] The primary rollers provide initial support for the mylar sheet, ensuring the stability of the mylar sheet during the processing, and at the same time helping to position the bending area of the mylar sheet. The primary rollers guide the mylar sheet to move along a predetermined path, ensuring that it correctly enters the mylar groove for bending. Before the mylar sheet starts to bend, the primary rollers help the mylar sheet to start preliminary deformation through their shape and position, preparing for the subsequent bending process. The primary rollers can disperse the stress borne by the mylar sheet during the bending process, reducing local stress concentration of the material and avoiding fracture or crack.
[0049] After the mylar sheet is preliminarily deformed by the primary rollers 320, the secondary rollers 330 continue to apply pressure to the mylar sheet, further pushing its deformation until the required bending is completed. The secondary rollers 330 are located in the mylar groove, and through their position and pressure, accurately control the bending angle and shape of the mylar sheet. During the process of the mylar sheet entering the bottom of the mylar groove, the secondary rollers 330 provide necessary support and guidance, ensuring that the mylar sheet moves along a predetermined path. The secondary rollers 330 help to disperse the stress on the mylar sheet during the bending process through their evenly distributed pressure, reducing the risk of material fracture or crack.
[0050] A primary elastic structure is respectively provided on each primary roller 320, and a secondary elastic structure is respectively provided on each secondary roller 330. The primary elastic structure and the secondary elastic structure are respectively used to maintain the positions of the primary roller 320 and the secondary roller 330. The elastic structure can absorb impact force, reduce the friction between the roller and the mylar sheet or the groove wall, and extend the service life of the roller and the equipment.
[0051] The primary elastic structure is used to maintain the rotational position of the primary roller 320, and the secondary elastic structure is used to maintain the relative position between the secondary roller 330 and the deformation base block 310. The primary elastic structure and the secondary elastic structure are respectively springs. The spiral direction of the spring of the primary elastic structure is parallel to the axis direction of the primary roller 320. One end of the primary elastic structure is hinged to the primary roller, and the other end is fixedly connected to the deformation base block 310. The spiral direction of the spring of the secondary elastic structure is consistent with the movement direction of the secondary roller. The primary roller 320 is rotatably connected to the frame 100, and the primary elastic structure controls the torque of the primary roller 320. The secondary roller 330 makes a relative displacement with the frame 100 in the secondary roller groove, and the secondary elastic structure controls the relative position between the secondary roller 330 and the frame 100.
[0052] The springs of the secondary elastic structure are respectively fixedly connected to the deformation base block 310 and hinged to the secondary roller 330. The hinged connection direction of the secondary elastic structure and the secondary roller is perpendicular to the acting direction of the secondary elastic structure. The acting direction of the secondary elastic structure is respectively perpendicular to the mylar groove surface. The elastic structure perpendicular to the groove surface can provide an effective supporting force for the secondary roller 330 to ensure its stability during the processing. Through the uniform pressure distribution, the quality of the mylar sheet bending can be improved, and it is ensured that the bending line is straight and consistent. The perpendicular elastic action can reduce the springback phenomenon of the mylar sheet after bending and improve the final accuracy of the product.
[0053] Through the buffering action of the primary elastic structure and the secondary elastic structure, the stress concentration during the bending process of the mylar sheet can be reduced, and the fracture risk caused by uneven stress can be lowered. The existence of the elastic structure makes the contact between the roller and the mylar sheet more uniform, which helps to improve the quality of bending and punching.
[0054] In the cross-section of the secondary roller groove, the notch size at the intersection with the deformation base block 310 is smaller than the diameter size of the secondary roller 330. The smaller notch size limits the movement range of the secondary roller, reduces the offset of the roller during the processing, and improves the processing accuracy. The smaller notch size can prevent the secondary roller from accidentally falling off during the processing, and improves the safety and reliability of the equipment.
[0055] A cutting die and a conveying unit are respectively provided on the frame 100. The cutting die is used for punching the Mylar sheet, and the conveying unit is used for moving and replacing the position of the Mylar sheet. The cutting die includes a punching blade and a punching power unit. The punching power unit drives the punching blade to move and punch the Mylar sheet, and the movement direction of the punching blade is perpendicular to the surface of the Mylar sheet. The conveying unit includes a conveyor belt and a robotic arm. The conveyor belt is used to transport the Mylar sheet blank and the processed Mylar sheet, and the robotic arm is used to adjust the position of the Mylar sheet blank and move the processed Mylar sheet. The cutting blade of the cutting die punches in a direction of movement perpendicular to the surface of the Mylar sheet, which helps to achieve precise cutting edges and sizes. The continuous transportation capacity of the conveyor belt combined with the efficient position adjustment and movement functions of the robotic arm increases the production volume per unit time.
[0056] By using components such as the pushing unit 200, the deformation unit 300, the cutting die and the conveying unit, the pushing unit 200 pushes the Mylar sheet to move, so that the Mylar sheet passes through the primary roller 320 and the secondary roller 330 in sequence, and finally reaches the Mylar groove for bending and then is punched by the cutting die. This can provide support for the bending and punching process of the Mylar sheet, avoid uneven stress in the bending and punching process, and solve the defect of the Mylar sheet breaking due to uneven stress during the bending and punching process in the prior art.
[0057] By using the primary roller first and then the secondary roller, the Mylar sheet undergoes a gradual deformation process, which helps reduce the elastic rebound of the material, improves the accuracy of the bending, and helps to distribute the stress more evenly, avoiding stress concentration points during the bending process and reducing the risk of material damage or breakage. The gradual deformation guidance helps to reduce the rebound phenomenon of the material after bending and ensure the accuracy of the bending angle.
[0058] After the processing is completed, under the action of the primary elastic structure and the secondary elastic structure, the secondary elastic structure generates a driving force on the side of the Mylar sheet, so that the Mylar sheet generates an upward force, driving the Mylar sheet to move upward, and the primary elastic structure drives the primary roller to rotate, and also exerts an upward force on the Mylar sheet, so that the Mylar sheet can be separated from the Mylar groove. And under the action of the primary elastic structure and the secondary elastic structure, the primary roller and the secondary roller can be reset and have the ability to prepare for the processing of the next Mylar sheet, with coherence and continuity.
[0059] There are several positioning posts fixedly arranged on a primary roller 320, and the several positioning posts are respectively arranged on the upper surface of the primary roller 320. The positioning posts can ensure the precise positioning of the mylar sheet during the processing, reducing the processing errors caused by position deviation. When the mylar sheet passes through the primary roller 320, the positioning posts can prevent the mylar sheet from sliding or shifting on the roller, keeping it stable. The positioning posts increase the mechanical strength of the roller, helping to withstand greater forces during the processing and improving the stability of the overall structure. The positioning posts are used to combine with the positioning holes on the mylar sheet to determine the orientation of the mylar sheet, which can avoid the mylar sheet from shifting during the processing and keep the mylar sheet tightly attached to the primary roller, ensuring that the mylar sheet can be closely attached to the pushing block and the mylar groove respectively during the processing, guaranteeing the accuracy and stress uniformity during the processing.
[0060] The cross-section of a primary roller 320 is a sector with an angle less than a flat angle, and the cross-section of an adjacent primary roller 320 is a semi-circle. Several positioning posts are fixedly arranged on the primary roller 320 with a semi-circular cross-section. The fixed arrangement of several positioning posts on the primary roller 320 with a semi-circular cross-section can maintain the fixed relationship between the positioning groove and the positioning posts, and enable the mylar sheet part on the positioning groove to have more contact surfaces with the primary roller 320 during the processing, ensuring the stability of the mylar sheet during the processing.
[0061] To achieve the above object, the second technical solution adopted by the present invention is: a processing technology of a continuous mylar processing device, including the following steps:
[0062] S1: Place the mylar sheet on several primary rollers 320, ensuring that the bent part of the mylar sheet is located between adjacent primary rollers 320. The support of the mylar sheet between the rollers helps to evenly distribute the stress during the bending process, reducing local deformation or damage of the material.
[0063] S2: Start the pushing unit 200 to push the mylar sheet downward. The mylar sheet successively passes through the horizontal plane where the primary roller 320 is located and the horizontal plane where the secondary roller 330 is located. By passing through the rollers at different horizontal planes in stages, the mylar sheet can achieve progressive bending, which helps to reduce the elastic springback of the material. The gradual pushing helps to more evenly distribute the stress during the bending process, avoiding material damage caused by local stress concentration.
[0064] S3: The mylar sheet gradually deforms in the mylar groove until the mylar sheet reaches the bottom of the mylar groove. The slow and controlled deformation helps to achieve a more precise bending angle and edge alignment, improving the product quality.
[0065] S4: The die cuts the mylar sheet that has been bent, and slowly removes the pushing unit 200 from the mylar sheet. The mylar sheet exits the mylar groove driven by the primary elastic structure and the secondary elastic structure, completing the mylar processing technology. The slow removal of the pushing unit 200 reduces the impact on the bent mylar sheet, avoiding damage or deformation.
[0066] The use of the primary elastic structure and the secondary elastic structure helps to smoothly guide the mylar sheet out of the mylar groove, reducing the additional stress on the material. The slow removal action helps to protect the surface of the mylar sheet, avoiding scratches or indentations during the exit process.
[0067] By precisely controlling the placement and pushing of the mylar sheet on the primary roller 320 and the secondary roller 330, the accuracy of the bending is ensured. The gradual deformation of the mylar sheet in the mylar groove helps to reduce the elastic springback of the material, improving the bending quality.
[0068] In S1, when the mylar sheet is placed on a number of primary rollers 320, one surface of each secondary roller 330 is horizontally arranged, and the horizontally arranged surfaces of the number of secondary rollers 330 are on the same horizontal plane. Ensuring that all secondary rollers 330 are on the same horizontal plane helps to apply a uniform force to the mylar sheet, achieving uniform bending and avoiding local stress concentration. The unified horizontal plane setting helps to improve the bending accuracy, ensuring that the bending angles and shapes of each mylar sheet are consistent.
[0069] In S2, the pushing speed of the pushing unit 200 gradually slows down, and the speed of the mylar sheet is 0 when it reaches the bottom of the mylar groove. Gradually decelerating to a stop can reduce the impact of the mylar sheet when it reaches the bottom of the groove, avoiding material damage or fracture caused by sudden stopping. The deceleration process of controlling the speed helps to more precisely control the bending position and angle of the mylar sheet, ensuring the consistency and accuracy of the bending. By controlling the deceleration process, the springback phenomenon of the material after bending can be reduced, ensuring the accuracy of the bending angle.
[0070] Based on the inspiration of the ideal embodiments of the present invention above, through the above description, relevant personnel can completely make various changes and modifications without departing from the technical idea of this invention. The technical scope of this invention is not limited to the content in the specification, and the technical scope must be determined according to the scope of the claims.
