Abstract
Description
Technical Field
[0001] This invention relates to the field of automatic film shaping and positioning technology, specifically an automatic shaping and positioning device and method for flexible contact film patching. Background Technology
[0002] Flexible film mounting usually refers to the mounting process on flexible circuit boards. It uses flexible materials such as polyimide as the substrate and has the characteristics of being bendable and foldable. It is used to fix electronic components on flexible substrates to achieve circuit connection and can realize complex circuit connection in a limited space.
[0003] Due to the bendable and foldable nature of flexible films, wrinkles are very likely to appear after production. These wrinkles increase the thickness, which can cause excessive pressure on surrounding components, leading to poor soldering or component damage. Furthermore, the tips of the wrinkles become stress concentration points, making them prone to cracking during vibration or bending tests. In addition, when mounting flexible films, they need to be positioned to ensure proper circuit operation and precise alignment with components, preventing product malfunction.
[0004] Currently, the main methods for shaping and positioning flexible films include manual operation, fixture or jig assistance, and fully automated vision placement systems. Among these, the fixture or jig assistance method is the most widely used and cost-effective shaping and positioning method. However, in the process of fixture-assisted shaping and positioning, since the fixture is customized for a specific model of PCB and film, once the film is changed, the fixture must be redesigned and replaced. Furthermore, during the shaping process, for particularly soft and easily stretchable films, the mechanical constraints of the cavity alone may not be sufficient for perfect shaping, resulting in slight wrinkles in the film and a decrease in the performance of the final mounted product. Summary of the Invention
[0005] The purpose of this invention is to provide an automatic shaping and positioning device for flexible contact film patches, so as to solve the problems mentioned in the background art.

[0009] The automatic shaping and positioning device for flexible contact film patch as described above: the moving component includes pulleys rotatably mounted on the shelf, two sets of pulleys are symmetrically arranged along the length of the shelf, a belt is arranged between the two sets of pulleys, a moving block is fixedly mounted on the belt, the mounting frame is fixedly connected to the moving block, and a trigger rod is also fixedly mounted on the moving block, the trigger rod is slidably connected to the inclined rail fixedly mounted on the lifting frame.
[0010] The automatic shaping and positioning device for flexible contact film patch as described above: the linkage structure includes a collar fixedly connected to the adsorption head, the collar being slidably connected to a guide rod fixedly mounted on the mounting frame, and a slider being fixedly mounted on the collar, the slider being connected to a toothed plate slidably mounted on the worktable, and the toothed plate meshing with a drive gear coaxially fixedly mounted on the rotating rod.
[0011] The automatic shaping and positioning device for flexible contact film patch as described above: the driving component includes a driving element, a first driving structure and a second driving structure. The first driving structure includes a first driving rod rotatably mounted on the shelf. The first driving rod is connected to one of the pulleys through a first bevel gear set, and a fitting groove is provided on the outer wall of the first driving rod.
[0012] The automatic shaping and positioning device for flexible contact film patch as described above: the second drive structure includes a second drive rod rotatably mounted on the shelf, the second drive rod is connected to a linkage rod rotatably mounted on the shelf via a linkage belt, a sliding sleeve is slidably disposed on the linkage rod, the sliding sleeve is connected to the rotating rod via a second bevel gear set, and a composite groove is formed on the outer wall of the second drive rod.
[0013] The automatic shaping and positioning device for flexible contact film patch as described above: the driving component includes a first sleeve sleeved on the first driving rod and a second sleeve sleeved on the second driving rod. The first driving rod is fixedly connected to the second sleeve and connected to an electric telescopic rod fixedly installed on the shelf.
[0014] The automatic shaping and positioning device for flexible contact film patching as described above: a positioning block is also fixedly installed on the worktable, and a positioning groove is opened on the positioning block.
[0015] An automatic shaping and positioning method for flexible contact film patches is also proposed, which uses the automatic shaping and positioning device for flexible contact film patches as described above, and includes the following steps: Step 1: In the initial state, the suction head is located above the positioning block, and the leveling component is away from the worktable; when performing shaping and positioning, start the electric telescopic rod, and then the drive component slides back and forth along the length of the shelf; Step 2: During the operation of the driving component, the first driving rod moves first, driving the moving component to move the suction head toward the leveling station. During the movement of the suction head, the trigger rod cooperates with the inclined rail to drive the leveling component to adhere to the film placed on the worktable. Step 3: After the adsorption head moves to the leveling station, the second drive rod moves, driving the lifting component to move the adsorption head closer to the film. At the same time, the linkage structure drives the leveling component to smooth and shape the film until the drive component moves in the opposite direction, at which point the adsorption action of the film is completed. Step 4: The drive component reverses its movement. At this time, the suction head rises under the drive of the moving component until it returns to the initial height. Then, the moving component moves and pulls the suction head back to the initial positioning position. Immediately afterwards, the lifting component moves again and drives the suction head down. During this process, the positioning block can position the film adsorbed on the suction head.
[0016] Compared with the prior art, the beneficial effects of the present invention are: By setting up a leveling component, the cooperation between the drive gear and the toothed plate can drive two sets of pressure plates to slide from the middle of the film to both sides. The contact friction between the pressure plates and the film smooths out the bends and wrinkles that the film itself produces, ensuring that the film can be flatly attached to the worktable so that the film can be bonded to the PCB board in the future, thereby improving the bonding quality. In addition, during the shaping process, the spring set in the leveling component can make the pressure plates shape films with different properties with appropriate force, thereby avoiding damage to the flexible film caused by excessive pressure and improving the overall practicality of the device. By setting up a positioning block, during the process of the suction head driving the film down, the positioning block with an inclined positioning groove and the film can be contacted and cooperated to enable the film to automatically fine-tune its position during the descent, ensuring that the center of the film is precisely aligned with the center of the positioning groove. This allows the film to be positioned, providing a prerequisite for subsequent patch placement operations. Meanwhile, by setting up a drive component, a moving component, and a lifting component, the drive component drives the moving component and the lifting component to move alternately, enabling the adsorption head to complete the adsorption, transfer, and positioning processes in succession. The entire process requires no manual intervention, and the film shaping and smoothing operation can be completed simultaneously before the adsorption head performs adsorption, so that the entire automatic film shaping and positioning operation can be completed quickly.

[0029] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.
[0030] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.
[0031] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.
[0032] Please see Figures 1-11 In this embodiment of the invention, an automatic shaping and positioning device for flexible contact film patches includes: A shelf 3 is fixedly installed on the workbench 1. A mounting frame 9 and a lifting frame 5 are slidably arranged on the shelf 3. An adsorption head 10 is provided on the mounting frame 9. A positioning block 2 is also fixedly installed on the workbench 1, and a positioning groove 201 is provided on the positioning block 2; For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The aforementioned positioning block 2 is provided with a positioning groove 201, and the groove wall of the positioning groove 201 is as follows: Figure 3 As shown, a certain tilt angle is set. During the process of the subsequent adsorption head 10 adsorbing the film and descending, the film can move relative to the adsorption head 10 under the contact restriction of the positioning groove 201 wall, so that the center of the final film coincides with the center of the positioning groove 201, thereby realizing the positioning of the film so that the subsequent placement machine can perform the placement operation.
[0033] The lifting frame 5 is connected to the adsorption head 10 through a linkage structure, and a leveling component is also provided on the lifting frame 5. The leveling assembly includes a rotating rod 6 rotatably mounted on the lifting frame 5. Two sets of sleeves 16 are symmetrically slidably arranged on the rotating rod 6. The inner wall of the sleeve 16 forms a first protrusion 1601. The first protrusion 1601 is slidably arranged in a spiral groove 601 opened on the rotating rod 6. A sliding rod 17 is also fixedly arranged on the sleeve 16. A spring 18 is sleeved on the sliding rod 17. One end of the spring 18 abuts against the sleeve 16, and the other end abuts against the pressure plate 15 which is slidably arranged. For details, please refer to Figure 5 , Figure 6 A locking block 1602 is fixedly installed on the aforementioned sleeve 16. The locking block 1602 is slidably disposed in a groove opened on the lifting frame 5. With the cooperation of the locking block 1602 and the groove, the sleeve 16 can only slide in the axial direction of the rotating rod 6. The aforementioned pressure plate 15 is arranged in an "L" shape. In the initial state, the two sets of sleeves 16 drive the pressure plate 15 to move closer to each other. At this time, the two sets of pressure plates 15 are in close contact with each other, such as... Figure 5This is the state shown, so that the subsequent pressure plate 15 can smooth and shape the film placed on the worktable 1.
[0034] Further, please refer to Figures 1-8 The suction head 10 is connected to the lifting component on the shelf 3, the mounting frame 9 is connected to the moving component on the shelf 3, and the shelf 3 is also provided with a drive component, which is connected to the lifting component and the moving component and can drive the moving component and the lifting component to move alternately. The lifting assembly includes a rotating rod 11 rotatably mounted on the mounting frame 9. A lifting sleeve 21 fixedly connected to the adsorption head 10 is sleeved on the rotating rod 11. A second protrusion 2101 is formed on the inner wall of the lifting sleeve 21. The second protrusion 2101 is slidably disposed in a closed groove 1101 opened on the outer wall of the rotating rod 11. Specifically, please refer to Figure 7 The aforementioned closed groove 1101 is a circular groove formed around the rotating rod 11; and in the initial state, the aforementioned lifting sleeve 21 is far away from the worktable 1, and due to the cooperation of the linkage structure, the lifting sleeve 21 can only drive the suction head 10 to move up and down along the axial direction of the rotating rod 11. In detail, when the rotating rod 11 is subjected to external force and rotates continuously in the same direction for one revolution, the contact compression generated by the closed groove 1101 on the second protrusion 2101 can force the lifting sleeve 21 to drive the adsorption head 10 to rise and fall, thereby adsorbing and transferring the film placed on the worktable 1.
[0035] Further, please refer to Figures 1-4 , Figures 7-9 The moving component includes pulleys 28 rotatably mounted on the shelf 3. Two sets of pulleys 28 are symmetrically arranged along the length of the shelf 3. A belt is provided between the two sets of pulleys 28. A moving block 29 is fixedly mounted on the belt. The mounting frame 9 is fixedly connected to the moving block 29. A trigger rod 14 is also fixedly mounted on the moving block 29. The trigger rod 14 is slidably connected to the inclined rail 4 fixedly mounted on the lifting frame 5. Specifically, the aforementioned movable block 29 is fixedly connected to one of the running ends of the belt. When the belt is driven by the pulley 28 to rotate continuously in the same direction, the movable block 29 can pull the mounting frame 9 to slide along the length of the shelf 3 under the guidance of the belt, so that the adsorption head 10 can switch between the positioning station and the shaping station to perform the adsorption and positioning operation of the film.
[0036] Furthermore, please refer to Figures 1-4 , Figure 7The linkage structure includes a collar 22 fixedly connected to the adsorption head 10. The collar 22 is slidably connected to the guide rod 12 fixedly mounted on the mounting frame 9. A slider 2201 is fixedly mounted on the collar 22. The slider 2201 is connected to the toothed plate 8 slidably mounted on the worktable 1. The toothed plate 8 meshes with the drive gear 7 coaxially fixedly mounted on the rotating rod 6. In the initial state, the suction head 10 is located at the positioning station (directly above the positioning block 2). When the film is being shaped and positioned, the drive assembly is started first. Then, the drive assembly first causes the moving assembly to move, so that the moving block 29 moves the mounting frame 9 and the suction head 10 toward the shaping station. During this process, the trigger rod 14, which is fixed to the moving block 29, slides in the inclined rail 4, which can force the inclined rail 4 to move the lifting frame 5 and the leveling assembly to descend, so that the pressure plate 15 is in contact with the film on the worktable 1 (in particular, during this process, due to the setting of the spring 18, the pressure plate 15 can press on different films with appropriate force, reducing the pressure damage to the film caused by the pressure plate 15 during the shaping process, and improving the overall practicality of the device. During the descent of the lifting frame 5, the drive gear 7 does not engage with the toothed plate 8). At the same time, the slider 2201 slides along the slide rail 13, so that the toothed plate 8 is maintained at its original height. When the adsorption head 10 moves to the shaping station, the slider 2201 moves to the end of the travel of the slide rail 13; then, the drive component drives the lifting component to move, and then the rotating rod 11 drives the lifting sleeve 21 to lower the adsorption head 10. At the same time, the slider 2201 can drive the slide rail 13 and the toothed plate 8 to lower. During this process, the toothed plate 8 and the drive gear 7 enter the meshing transmission state, which can drive the rotating rod 6 to rotate. At this time, with the cooperation of the spiral groove 601 and the first protrusion 1601, the two sets of sleeves 16 drive the two sets of pressure plates 15 to slide from the middle position of the film to both sides. During the sliding process, the contact friction generated by the pressure plate 15 on the film can smooth out the bending or wrinkles of the film itself, so that the film can be completely attached to the worktable 1, so that the subsequent pick and place machine can attach the film to the PCB board. Furthermore, as the two sets of pressure plates 15 move away from each other, the pressure plates 15 can make way for the adsorption head 10 so that the adsorption head 10 can adsorb the shaped film under negative pressure; until the adsorption head 10 descends to the lowest position, the two sets of pressure plates 15 are completely separated from the film, and the adsorption head 10 adsorbs the film under the drive of the sensor (not shown in the figure).
[0037] After adsorption is complete, the rotating rod 11 reverses, causing the adsorption head 10 to rise and reset. During this process, the adsorption head 10 will drive the leveled film to rise synchronously. At the same time, the collar 22 pulls the toothed plate 8 to rise, so that the drive gear 7 drives the rotating rod 6 to reverse, forcing the two sets of sleeves 16 to pull the two sets of pressure plates 15 back to the initial position.
[0038] Subsequently, the drive component drives the moving component to move, so that the moving block 29 moves the mounting bracket 9 and the suction head 10 along the length direction toward the positioning station. After the suction head 10 returns to the positioning station, the drive component drives the lifting component to move again. At this time, the suction head 10 drives the leveled film to descend. During the descent, the film is shifted with the cooperation of the positioning groove 201 until the suction head 10 descends to the lowest position, and the film coincides with the center of the positioning groove 201, thereby realizing the automatic positioning operation of the film.
[0039] For details, please refer to Figures 9-11 The driving assembly includes a driving component, a first driving structure, and a second driving structure. The first driving structure includes a first driving rod 23 rotatably mounted on the shelf 3. The first driving rod 23 is connected to one of the pulleys 28 through a first bevel gear set, and a fitting groove is provided on the outer wall of the first driving rod 23. The fitting groove includes a rotating groove 2301 formed on the first drive rod 23, and the first vertical groove 2302 and the second vertical groove 2303 are respectively connected to the first and the last ends of the rotating groove 2301.
[0040] The second driving structure includes a second driving rod 24 rotatably mounted on the shelf 3. The second driving rod 24 is connected to a linkage rod 19 rotatably mounted on the shelf 3 via a linkage belt. A sliding sleeve 20 is slidably disposed on the linkage rod 19. The sliding sleeve 20 is connected to the rotating rod 11 via a second bevel gear set. A composite groove is formed on the outer wall of the second driving rod 24. The composite groove includes an axial groove 2401 formed on the second drive rod 24, and the first and last ends of the axial groove 2401 are respectively connected to a first arc groove 2402 and a second arc groove 2403.
[0041] The driving component includes a first sleeve 26 sleeved on the first driving rod 23 and a second sleeve 27 sleeved on the second driving rod 24. The first driving rod 23 is fixedly connected to the second sleeve 27 and connected to an electric telescopic rod 25 fixedly installed on the shelf 3. A third protrusion is formed on the inner wall of the first sleeve 26 and the third protrusion is slidably disposed in the fitting groove. A fourth protrusion is formed on the inner wall of the second sleeve 27 and the fourth protrusion is slidably disposed in the composite groove. In the initial state, the third protrusion is located at the connection between the rotating groove 2301 and the second vertical groove 2303, and the fourth protrusion is located at the connection between the axial groove 2401 and the second arc-shaped groove 2403. During the automatic film shaping and positioning operation, the electric telescopic rod 25 is activated. The telescopic rod of the electric telescopic rod 25 then pushes the first sleeve 26 and the second sleeve 27 to slide. During this process, the third protrusion slides along the rotating groove 2301, and the fourth protrusion slides along the axial groove 2401. At this time, the first drive rod 23 rotates and, with the cooperation of the first bevel gear set, drives the pulley 28 to rotate, thereby driving the moving component to move. When the moving component moves, the mounting bracket 9 can slide along the length of the shelf 3, transferring the suction head 10 from the positioning station to the shaping station. Simultaneously, it drives the leveling assembly... The part descends to the leveling station; until the third protrusion moves to engage with the first vertical groove 2302, the fourth protrusion moves to contact the first arc groove 2402; with the continued pushing of the electric telescopic rod 25, the fourth protrusion cooperates with the first arc groove 2402, which can drive the lifting assembly to move, so that the second drive rod 24 rotates, and when the electric telescopic rod 25 is stretched to the maximum extent, the second drive rod 24, with the cooperation of the linkage belt, linkage rod 19, sliding sleeve 20 and the second bevel gear set, drives the rotating rod 11 to rotate half a turn, so as to drive the suction head 10 to descend; during this process, due to the cooperation of the linkage assembly, the leveling assembly can smooth and shape the film placed on the worktable 1, until the suction head 10 descends to the lowest position, the suction head 10 can adsorb the smoothed and shaped film; Subsequently, the electric telescopic rod 25 begins to retract. During the retraction process, the third protrusion slides along the first vertical groove 2302, and the fourth protrusion slides in the first arc groove 2402, driving the second drive rod 24 to rotate the rotating rod 11 half a turn so that the suction head 10 can lift the shaped film. Until the fourth protrusion engages with the axial groove 2401, the third protrusion engages with the rotating groove 2301, driving the first drive rod 23 to reverse the belt, so that the moving block 29 drives the suction head 10 to slide along the length of the shelf 3 until the third protrusion engages with the second vertical groove 2303, the suction head 10 returns to the shaping position; as the electric telescopic rod 25 continues to retract, the third protrusion slides along the second vertical groove 2303, and the fourth protrusion slides along the second arc groove 2403. During this process, the second drive rod 24 drives the rotating rod 11 to rotate half a turn again, so that the suction head 10 drives the film to descend and cooperate with the positioning groove 201 for positioning; until the electric telescopic rod 25 retracts to the limit position, the rotating rod 11 descends to the lowest position, completing the positioning operation of the film, and at the same time the fourth protrusion moves to the end of the stroke of the second arc groove 2403; Immediately afterwards, the electric telescopic rod 25 will extend back to its initial position and then stop. During this process, the fourth protrusion cooperates with the second arc-shaped groove 2403 to drive the second drive rod 24 to rotate the rotating rod 11 in reverse so that the suction head 10 returns to its initial height; so that the next set of film shaping and positioning operations can be carried out.
[0042] An automatic shaping and positioning method for flexible contact film patches is also proposed, which uses the automatic shaping and positioning device for flexible contact film patches as described above, and includes the following steps: Step 1: In the initial state, the adsorption head 10 is located above the positioning block 2 (positioning station), and the leveling component is away from the worktable 1; when performing shaping and positioning, the electric telescopic rod 25 is activated, and then the drive component slides back and forth along the length of the shelf 3. Step 2: During the operation of the driving component, the first driving rod 23 moves first, driving the moving component to move the suction head 10 toward the leveling station. During the movement of the suction head 10, the trigger rod 14 cooperates with the inclined rail 4, which can drive the leveling component to adhere to the film placed on the worktable 1. Step 3: After the adsorption head 10 moves to the leveling station, the second drive rod 24 is activated, driving the lifting component to move the adsorption head 10 closer to the film. At the same time, the linkage structure drives the leveling component to smooth and shape the film until the drive component reverses its movement, at which point the adsorption action of the film is completed. Step 4: The driving component reverses its movement. At this time, the adsorption head 10 rises under the drive of the moving component until it returns to the initial height. Then, the moving component moves to pull the adsorption head 10 back to the initial positioning position. Immediately afterwards, the lifting component moves again to drive the adsorption head 10 down. During this process, the positioning block 2 can position the film adsorbed on the adsorption head 10.

10. An automatic shaping and positioning method for flexible contact film patches, characterized in that, The automatic shaping and positioning device for flexible contact film patching as described in claim 1 includes the following steps: Step 1: In the initial state, the suction head (10) is located above the positioning block (2), and the leveling component is away from the worktable (1); when performing shaping and positioning, the electric telescopic rod (25) is started, and then the drive component slides back and forth along the length of the shelf (3); Step 2: During the operation of the driving component, the first driving rod (23) moves first, driving the moving component to move the suction head (10) toward the leveling station. During the movement of the suction head (10), the trigger rod (14) cooperates with the inclined rail (4) to drive the leveling component to adhere to the film placed on the worktable (1). Step 3: After the adsorption head (10) moves to the leveling station, the second drive rod (24) moves, driving the lifting component to move the adsorption head (10) closer to the film. At the same time, the linkage structure drives the leveling component to smooth and shape the film until the drive component moves in the opposite direction, and the adsorption action of the film is completed. Step 4: The driving component reverses its movement. At this time, the adsorption head (10) rises under the drive of the moving component until it returns to the initial height. Then, the moving component moves and pulls the adsorption head (10) back to the initial positioning position. Immediately afterwards, the lifting component moves again and drives the adsorption head (10) to descend. During this process, the positioning block (2) can position the film adsorbed on the adsorption head (10).
