Description

Technical Field

[0001] This utility model relates to the technical field of insulating sheet production equipment, specifically to an insulating sheet bending and forming device. Background Technology

[0002] Insulating sheets are widely used in electrical and electronic products, serving as insulation and separators. As a crucial component, the bending and forming process of insulating sheets is paramount. Traditional insulating sheet bending and forming equipment has several shortcomings. For example, the "Automatic Bending and Forming Equipment for PC Insulating Sheets" disclosed in patent document CN210552965U, while employing multiple cylinders to simultaneously perform feeding and bending, and allowing for simultaneous bending at multiple points, reducing the equipment and labor required for insulating sheet processing and improving production efficiency, still presents some problems in practical applications.

[0003] First, the bending accuracy of this equipment is relatively low. Because it uses a cylinder-driven bending method, the stroke and force control precision of the cylinder are limited, making it difficult to guarantee the accuracy of the bending angle and shape of the insulating sheet. This can lead to unstable bending quality of the insulating sheet, affecting the assembly quality and performance of electronic equipment. Furthermore, the automation level of this equipment needs improvement. While the feeding and bending processes have achieved a certain degree of automation, manual intervention is still required in the material changing and finished product collection stages. This not only increases labor costs but may also introduce additional quality risks due to the instability of manual operation.

[0004] In summary, existing insulating sheet bending and forming equipment suffers from high costs, low bending accuracy, and insufficient automation. These problems limit further improvements in insulating sheet production efficiency and the stable enhancement of product quality. Therefore, to address the shortcomings of existing technologies, this invention proposes a novel insulating sheet bending and forming device, aiming to solve the aforementioned technical problems, improve the production efficiency and quality of insulating sheet bending and forming, reduce equipment costs and manual intervention, and achieve more efficient, stable, and precise insulating sheet bending and forming.

[0015] (III) Beneficial Effects

[0016] This utility model provides an insulating sheet bending and forming device, which has the following beneficial effects:

[0017] 1. This utility model, through the combined drive of a servo motor and an electric cylinder, enables precise control of the bending angle and shape of the insulating sheet. The servo motor has high-precision angle control capability, accurately driving the ring body to rotate 90 degrees, thereby precisely moving the forming assembly to any side of the insulating sheet. Simultaneously, the electric cylinder has high stroke and force control precision, ensuring precise and stable pushing action of the first and second forming blocks on the edge of the insulating sheet, thus achieving precise bending of the insulating sheet edge. Furthermore, the lead screw and sliding block structure in the forming assembly allows the user to adjust the lateral position of the sliding block by rotating the handle, thereby adjusting the positions of the first and second electric cylinders to accommodate the bending requirements of insulating sheets of different specifications, further improving the flexibility and precision of bending. This high-precision bending method effectively solves the problem of low bending accuracy caused by the limited stroke and force control precision of cylinders in existing technologies, significantly improving the stability of the insulating sheet bending quality, and thus enhancing the assembly quality and performance of electronic devices.

[0018] 2. This invention achieves fully automated operation from material feeding and bending to finished product collection. The first servo motor in the material changing unit drives the internal gear ring to rotate, causing the suction cups on the material plate to sequentially complete the actions of picking up material from the feeding cylinder, moving the insulating sheet to the lower pressure plate, and moving the bent insulating sheet to the receiving cylinder. The entire process requires no manual intervention. Simultaneously, the push plate inside the feeding cylinder is driven upwards by a third servo electric cylinder, pushing the insulating sheet into the suction cup's adsorption range, further improving the automation level of material feeding. This highly automated production method not only reduces labor costs but also avoids quality risks introduced by the instability of manual operation, improving production efficiency and product quality stability. Compared with existing technologies, this invention significantly improves the degree of automation, enabling a more efficient and stable insulating sheet bending and forming process, meeting the stringent requirements of modern electronic equipment manufacturing for production efficiency and product quality.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0031] Please see Figures 1 to 7 The present invention provides a technical solution: an insulating sheet bending and forming device, comprising a support cabinet 1, a support platform 2, a control board, a bending component, and a material changing component. The support platform 2 is fixedly installed on the support cabinet 1, the control board is installed inside the support cabinet 1, and the bending component and the material changing component are both installed on the support platform 2. The control board is connected to the bending component and the material changing component for control.

[0032] The support cabinet 1 supports and fixes the support platform 2. The support platform 2 serves as a carrier, supporting the bending component and the material changing component. The bending component is used to fold any edge of the insulating sheet 28. The material changing component is used to deliver the insulating sheet 28 to the bending component and to remove the folded insulating sheet 28 from the bending component.

[0033] The bending components include a fixing assembly, a forming assembly, and a repositioning assembly. A circular opening is provided on the support platform 2.

[0034] The fixing assembly includes an upper pressure plate 12 and a lower pressure plate 14, which clamp and fix the insulating sheet 28 from above and below, respectively. The fixing assembly also includes a first servo electric cylinder 11, a second servo electric cylinder 13, a support plate 5, and two support rods 29. The second servo electric cylinder 13 is fixedly installed inside the support cabinet 1. The lower pressure plate 14 is detachably installed at the output shaft end of the second servo electric cylinder 13, which pushes the lower pressure plate 14 to move up and down. The two support rods 29 are fixedly installed above the support platform 2, and are located on both sides of the circular opening. The support plate 5 is fixedly installed on the upper ends of the two support rods 29. The cylinder barrel of the first servo electric cylinder 11 is fixedly installed on the support plate 5. The upper pressure plate 12 is detachably installed at the output shaft end of the first servo electric cylinder 11, which drives the upper pressure plate 12 to move up and down. The upper pressure plate 12 is located above the lower pressure plate 14.

[0035] The fixing component is used to clamp and fix the insulating sheet 28 and to drive the insulating sheet 28 to move up and down. The second servo electric cylinder 13 is used to drive the lower pressure plate 14 to move up and down. The first servo electric cylinder 11 is used to drive the upper pressure plate 12 to move up and down. The lower pressure plate 14 is used to support the insulating sheet 28 from below, and the upper pressure plate 12 is used to press and fix the insulating sheet 28 from above. The upper pressure plate 14 and the lower pressure plate 12 clamp and fix the insulating sheet 28, and the four edges of the insulating sheet 28 are exposed, leaving folded edge parts. The support plate 5 and the two support rods 29 are used to support and fix the first servo electric cylinder 11.

[0036] The transposition assembly includes a ring body 15 and a second servo motor 16. The ring body 15 is rotatably mounted on the circular opening of the support platform 2, meaning that the ring body 15 is rotatably mounted on the support platform 2 and located at the circular opening. The second servo motor 16 is fixedly mounted on the lower surface of the support platform 2 and is drively connected to the ring body 15. The second servo motor 16 drives the ring body 15 to rotate 90 degrees counterclockwise or clockwise on the support platform 2. The transposition assembly also includes a second gear 17. The lower surface of the ring body 15 has multiple tooth grooves, and each tooth groove is arranged circumferentially along the lower surface of the ring body 15. The second gear 17 is fixedly mounted on the output shaft end of the second servo motor 16, and the teeth of the second gear 17 mesh with the tooth grooves of the ring body 15.

[0037] The positioning component drives the forming component to rotate 90 degrees counterclockwise or clockwise, allowing it to move to any position around the clamped insulating sheet 28. This facilitates the forming component folding any side of the insulating sheet 28, thus completing the bending process. After the second servo motor 16 starts, its output shaft drives the second gear 17 to rotate. The second gear 17 pushes the meshing annular body 15 to rotate 90 degrees counterclockwise or clockwise on the support platform 2. The annular body 15 then drives the guide frame 18 to rotate 90 degrees counterclockwise or clockwise, adjusting its position so that it is positioned at the side of the clamped insulating sheet 28.

[0038] The forming assembly includes a guide frame 18, a first electric cylinder 22, a first forming block 23, a second electric cylinder 24, and a second forming block 25. The guide frame 18 is fixedly mounted on the annular body 15. The first electric cylinder 22 is mounted on the guide frame 18 and is positioned below the guide frame 18 at an angle. The first forming block 23 is fixedly mounted on the output shaft end of the first electric cylinder 22. The second electric cylinder 24 is mounted on the guide frame 18 and is positioned above the guide frame 18 at an angle.

[0039] Among them, reference Figure 7 The first electric cylinder 22 drives the first molding block 23 to move in an inclined direction. When the first molding block 23 moves closer to the clamped and fixed insulating sheet 28, the first molding block 23 applies an inclined pressure to one side edge of the insulating sheet 28, thereby bending the edge of the insulating sheet 28 downwards, achieving the purpose of bending the edge of the insulating sheet 28 downwards. (Reference) Figure 6 The second electric cylinder 24 drives the second molding block 25 to move in an inclined direction. When the second molding block 25 moves closer to the clamped and fixed insulating sheet 28, it pushes one side edge of the insulating sheet 28 in an inclined direction, thereby bending the edge of the insulating sheet 28 upward, achieving the purpose of folding the edge of the insulating sheet 28 upward. The arrangement of the first electric cylinder 22, the first molding block 23, the second electric cylinder 24, and the second molding block 25 meets the needs of folding the edge of the insulating sheet 28 upward or downward, improving the applicability of the entire device.

[0040] Specifically, the forming assembly also includes a lead screw 19, a handle 20, and a sliding block 21. The sliding block 21 is slidably mounted on the guide frame 18, and the lead screw 19 is rotatably mounted on the guide frame 18. The middle part of the lead screw 19 passes through the sliding block 21, and the two are threadedly connected. The handle 20 is fixedly mounted on the outer wall of one end of the lead screw 19. The upper and lower surfaces of the sliding block 21 are both inclined. The second electric cylinder 24 and the first electric cylinder 22 are respectively fixedly mounted on the upper and lower surfaces of the sliding block 21.

[0041] The rotating handle 20 drives the lead screw 19 to rotate, which in turn pushes the sliding block 21, which is threadedly connected to it, to move. The sliding block 21 slides on the guide frame 18, thereby adjusting its lateral position. The sliding block 21 drives the first electric cylinder 22 and the second electric cylinder 24 to move laterally, thereby adjusting their lateral positions. This allows for adjustment of the folding position during folding to accommodate the folding requirements of insulating sheets 28 of different specifications.

[0042] Specifically, a feeding cylinder 3 and a receiving cylinder 4 are respectively inserted on the support platform 2. The feeding cylinder 3 contains multiple insulating sheets 28 stacked from top to bottom. The material changing component drives the insulating sheets 28 in the feeding cylinder 3 to move onto the lower pressure plate 14. The bending component folds the edges of the insulating sheets 28. The material changing component drives the folded insulating sheets 28 to move into the receiving cylinder 4.

[0043] The feeding cylinder 3 is used to hold multiple insulating sheets 28 stacked from top to bottom. The receiving cylinder 4 is used to hold the folded insulating sheets 28.

[0044] More specifically, the material changing component includes a support cylinder 6, an internal gear ring 7, a first servo motor 8, and four material plates 9. The support cylinder 6 is fixedly mounted on the support platform 2. The internal gear ring 7 is fitted onto the outer wall of the support cylinder 6 and the two are rotatably connected. The first servo motor 8 is fixedly mounted on the support cylinder 6, and its output shaft is connected to the internal gear ring 7. The first servo motor 8 drives the internal gear ring 7 to rotate 90 degrees counterclockwise. The four material plates 9 are arranged in a circular array on the outer wall of the internal gear ring 7, with one end of each material plate 9 fixedly connected to the outer wall of the internal gear ring 7, and a suction cup 10 fixedly mounted on the lower surface of the other end of each material plate 9. A first gear is fixedly mounted on the output shaft of the first servo motor 8, and the first gear meshes with the internal gear ring 7.

[0045] The material changing component also includes a vacuum generator, whose pressure-operated end is connected to the suction cup 10 via a flexible conduit. After the suction cup 10 is in close contact with the insulating sheet 28, the vacuum generator creates a vacuum inside the suction cup 10 via the flexible conduit, thereby enabling the suction cup 10 to adsorb the insulating sheet 28.

[0046] When the first servo motor 8 starts, its output shaft drives the first gear to rotate. The first gear pushes the internal gear ring 7, which meshes with it, to rotate 90 degrees counterclockwise. The internal gear ring 7 then drives each material plate 9 to rotate 90 degrees counterclockwise, and the material plate 9 drives the suction cup 10 to rotate 90 degrees, so that the suction cup 10 can be positioned above the feeding cylinder 3, the lower pressure plate 14, and the receiving cylinder 4 in sequence. When the suction cup 10 is positioned above the feeding cylinder 3, it adsorbs and fixes the insulating sheet 28 located inside the feeding cylinder 3. After the suction cup 10 rotates the insulating sheet 28 90 degrees counterclockwise and moves it to a position above the lower pressure plate 14, the suction cup 10 releases its suction and fixation on the insulating sheet 28. The insulating sheet 28 is then placed on the lower pressure plate 14. The bending component folds the edge of the insulating sheet 28 located on the lower pressure plate 14. After the insulating sheet 28 is folded, the suction cup 10 holds the folded insulating sheet 28 in place and rotates it 90 degrees counterclockwise to a position above the receiving cylinder 4. Then, the suction cup 10 releases its suction and fixation on the insulating sheet 28, and the folded insulating sheet 28 falls into the receiving cylinder 4, thus realizing the edge folding (i.e., bending) work of the insulating sheet 28.

[0047] More specifically, a pusher plate 27 is slidably connected to the inner wall of the feed cylinder 3, and a third servo electric cylinder 26 is fixedly installed inside the support cabinet 1. The output shaft end of the third servo electric cylinder 26 is detachably installed to the pusher plate 27. Each insulating sheet 28, stacked sequentially from top to bottom, is placed on the pusher plate 27.

[0048] The third servo electric cylinder 26 is used to drive the push plate 27 to rise. After the third servo electric cylinder 26 is started, the output shaft of the third servo electric cylinder 26 pushes the push plate 27 to rise and move. The push plate 27 pushes the insulating sheets 28 located above it to rise and move, so that the insulating sheets 28 can move up and get closer to the suction cup 10, so that the suction cup 10 can adsorb and fix the insulating sheets 28.

[0049] The control board employs one of the following: a programmable logic controller (PLC) or an industrial computer. It contains internal software programs such as logic control programs and timing control programs to meet the automation control needs of various electrical devices within the device and to adjust relevant control parameters during the automation process. Details regarding this logic control aspect are omitted here. The control board is electrically connected (including communication connections) to the first servo motor 8, the first servo electric cylinder 11, the second servo electric cylinder 13, the second servo motor 16, the first electric cylinder 22, the second electric cylinder 24, and the third servo electric cylinder 26. The control board controls the start, stop, and operation of the first servo motor 8, the first servo electric cylinder 11, the second servo electric cylinder 13, the second servo motor 16, the first electric cylinder 22, the second electric cylinder 24, and the third servo electric cylinder 26 to meet the automation requirements of the entire device.

[0050] In use, the initial state is as follows: the feed cylinder 3 contains the insulating sheet 28 to be processed, the push plate 27 is located at the bottom of the feed cylinder 3, the third servo electric cylinder 26 is in the initial position, the suction cup 10 of the material changing component is located above the feed cylinder 3, the forming assembly of the bending component is in the initial position, and the upper pressure plate 12 and lower pressure plate 14 of the fixing component are in the open state.

[0051] Material feeding process: The third servo electric cylinder 26 is activated, pushing the pusher plate 27 upward and pushing the uppermost insulating sheet 28 into the suction range of the suction cup 10. The first servo motor 8 of the material changing component is activated, driving the internal gear ring 7 to rotate 90 degrees. The internal gear ring 7 drives the suction cup 10 to rotate through the material plate 9, causing the suction cup 10 to move above the feeding cylinder 3. The suction cup 10 generates a vacuum under the action of the vacuum generator, adsorbing and fixing the insulating sheet 28.

[0052] Material changing process: The first servo motor 8 starts again, driving the internal gear ring 7 to rotate 90 degrees, causing the suction cup 10 to move the insulating sheet 28 above the lower pressure plate 14. The suction cup 10 releases its suction and fixation of the insulating sheet 28, and the insulating sheet 28 is placed on the lower pressure plate 14.

[0053] Clamping and fixing process: The second servo electric cylinder 13 is activated, pushing the lower pressure plate 14 upward to clamp the insulating sheet 28 between the lower pressure plate 14 and the upper pressure plate 12. The first servo electric cylinder 11 is activated, driving the upper pressure plate 12 downward to further clamp the insulating sheet 28, ensuring that the insulating sheet 28 remains stable during bending. At the same time, the second servo electric cylinder 13 and the first servo electric cylinder 11 drive the insulating sheet 28 to be positioned on the moving trajectory of the first forming block 23 or the second forming block 25.

[0054] Bending process: The second servo motor 16 starts, driving the ring body 15 to rotate 90 degrees, moving the forming assembly to one side of the insulating sheet 28. The first electric cylinder 22 starts, driving the first forming block 23 to move in an inclined direction, applying an inclined pressure to one side of the insulating sheet 28, causing the edge of the insulating sheet 28 to bend downwards. (Alternatively, the second electric cylinder 24 starts, driving the second forming block 25 to move in an inclined direction, applying an inclined pressure to the same side of the insulating sheet 28, causing the edge of the insulating sheet 28 to bend upwards, completing the bending operation on that side.) The second servo motor 16 starts again, driving the ring body 15 to rotate 90 degrees, moving the forming assembly to the other side of the insulating sheet 28, repeating the above bending operation to complete the bending and forming of all sides of the insulating sheet 28.

[0055] Unloading process: The first servo electric cylinder 11 and the second servo electric cylinder 13 are activated, driving the upper pressure plate 12 and the lower pressure plate 14 respectively to release the insulating sheet 28. The first servo motor 8 is activated, driving the internal gear ring 7 to rotate 90 degrees, causing the suction cup 10 to move above the lower pressure plate 14. The suction cup 10 generates a vacuum under the action of the vacuum generator, adsorbing and fixing the bent insulating sheet 28. The first servo motor 8 is activated again, driving the internal gear ring 7 to rotate 90 degrees, causing the suction cup 10 to move the bent insulating sheet 28 above the receiving cylinder 4. The suction cup 10 releases its adsorption and fixing of the insulating sheet 28, and the insulating sheet 28 falls into the receiving cylinder 4, completing the bending and collection process of one insulating sheet 28.

[0056] Cyclic operation: Repeat the above processes of feeding, changing, clamping and fixing, bending and unloading to achieve continuous bending and forming and collection of multiple insulating sheets 28, thus completing the entire production process.

[0057] Through the detailed description of the working principle above, this utility model realizes fully automated operation from material feeding and bending to finished product collection, which significantly improves production efficiency and product quality stability, solves the problems existing in the prior art, and has high practical value and prospects for promotion and application.

[0058] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
