[0002] FPC (Flexible Printed Circuit) is a type of printed circuit board made of flexible substrate. It has the characteristics of being bendable, foldable, lightweight, and thin, and plays a key role in modern electronic products.

[0003] With the trend of highly integrated 3C products, FPC bending is a key technology for realizing three-dimensional circuit wiring. However, after the bending process, especially for products with excessively large bending angles, improper operation during the unloading process can easily lead to scratches or breakage. Existing common unloading mechanisms are insufficient to effectively ensure the safe, efficient, and automated unloading of bent FPC materials. Utility Model Content

[0015] Furthermore, the material handling head is provided in multiple ways, and the multiple material handling heads are connected to the rotating shaft at intervals;

[0016] Each of the aforementioned material-taking heads has a vacuum suction cup at one end of its bottom and a downward pressure head at the other end, which is vertically downward.

[0017] Furthermore, each of the pressing heads has a groove at its bottom.

[0018] Furthermore, a flipping limiting plate is provided vertically downward on the support arm, on the side facing the support bar, and the flipping limiting plate is located above the rotating shaft; it is spaced from the movement trajectory of the rotating shaft at a predetermined rotation angle.

[0019] Furthermore, a robotic arm is also provided on the support platform. When the material on the picking head is flipped to a predetermined angle, the robotic arm is used to unload the material from the picking head.

[0045] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0046] like Figures 1-10 As shown, this utility model provides an automatic FPC flipping and unloading device for automatically picking up, flipping, unloading and re-inspecting FPC materials that have been bent.

[0047] like Figure 2As shown, the FPC material 000 includes a strip-shaped portion 001 and an irregularly shaped portion 002 connected to one end of the strip-shaped portion. A preset bending surface is formed at the connection between the strip-shaped portion and the irregularly shaped portion. Several functional components 003 are provided on the upper surface of the strip-shaped portion at the other end away from the bending surface.

[0048] The device of this utility model includes a support platform 5, a rotating disk 1 is installed in the middle of the support platform 5, the rotating disk is driven by a drive mechanism (not shown) to rotate around its central axis, and at least one positioning fixture 2 is provided on the outer periphery of the rotating disk 1 for pressing FPC material. The rotating disk 1 drives the positioning fixture 2 to rotate.

[0049] On the support platform 5, within the rotation path of the positioning fixture 2, there is a lifting and opening module and a material picking and flipping module 3, which are spaced back and forth along the Y-axis. The lifting and opening module is used to drive the automatic unlocking and locking of the positioning fixture; the material picking and flipping module 3 is used to pick up and flip the FPC material in the positioning fixture. The specific structure is as follows:

[0050] In this embodiment of the invention, four notches are spaced apart on the outer periphery of the rotating disk 1, and a positioning fixture 2 is provided on each notch.

[0051] Each positioning fixture 2 includes a fixed base plate 21, a movable strip plate 22 and an upper cover plate 23 arranged sequentially from bottom to top, and the three are arranged in parallel to each other.

[0052] The fixed base plate 21 is detachably connected to the notch of the rotating disk at both ends by fasteners (e.g., bolts). The upper surface of the fixed base plate 21 has a sliding groove along the X direction on the outer side. At both ends of the sliding groove, a retaining block 212 is fixedly or detachably connected by fasteners. Each retaining block 212 has a retaining groove that runs through the X direction in the middle. An opening and closing hole 213 is opened in the middle of the fixed base plate 21.

[0053] The upper cover plate 23 is detachably connected to the base plate 21 along its length by fasteners at both ends. There are four independent processing stations along the X direction on its upper surface. Each processing station includes a lock compartment 231 and an adjacent material compartment 232.

[0054] Each material bin 232 is detachably connected to a positioning plate 24 for quick replacement to accommodate different specifications of FPC products.

[0055] The upper surface of the positioning plate 24 is provided with an L-shaped receiving surface 243 for placing the strip portion of the FPC material.

[0056] Each lock compartment 231 is equipped with a clamping component.

[0057] The clamping assembly includes a clamping plate 25 and an elastic element 26 slidably connected within the lock chamber along the X-direction. The clamping plate 25 includes a rod, the upper and lower ends of which extend horizontally towards the positioning plate to form an upper clamping strip and a lower clamping strip, respectively. A round shaft 251 is vertically mounted at the bottom of the upper clamping strip, and a clamping head 252 made of soft material is mounted on the end of the lower clamping strip facing the receiving surface. One end of the elastic element 26 is connected to a mounting hole on the rod, and the other end is connected to the inner wall of the lock chamber. The round shaft 251 passes downward through a mating hole and connects to a movable strip.

[0058] In its natural state, the elastic member 26 has the pressing head 252 positioned above the receiving surface, pressing and fixing the strip portion of the FPC material to form the locking state of the positioning fixture.

[0059] When the clamping plate is driven by an external force to overcome the operation of the elastic element 26 and moves in the X direction away from the receiving surface, the clamping head 252 disengages from the area above the receiving surface, thus forming the unlocked state of the positioning fixture.

[0060] The elastic element 26 of this utility model is a spring.

[0061] To facilitate the connection of the movable strip 22 and to drive the pressing plate in a linkage manner, a rectangular accommodating compartment is provided on the bottom surface of the upper cover plate 23 along its length. A limiting groove is provided in the accommodating compartment corresponding to the area above each of the material compartments 232.

[0062] The movable strip 22 is elongated and slides along the X-direction within the receiving chamber and the chute. On the upper surface of the movable strip 22, grooves 221 are provided corresponding to the four mating holes, and four round shafts 251 pass downwards through the corresponding mating holes and are accommodated within the corresponding grooves 221. A slide bar is fixedly attached to the lower surface of the movable strip 22 at the position corresponding to the aforementioned chute, and the bottom surface of the slide bar slides along the X-direction and engages with the slots of two locking blocks 212. A buffer block 223 is fixedly attached to the side of the movable strip 22 at the position corresponding to each limiting groove, and each buffer block 223 slides along the X-direction within the limiting groove. An elastic element 26 is connected to each buffer block 223, and the other end of each elastic element 26 is connected to the inner wall of the corresponding limiting groove, with the elastic elements on the four buffer blocks arranged in the same direction.

[0063] Furthermore, an elastic element 26 is connected to the side of the movable strip 22 opposite to the ramp surface 271 of the drive plate 27 (i.e., its left side), and the other end of the elastic element is connected to the inner wall of the groove of the fixed base plate.

[0064] When the moving strip 22 is subjected to an external driving force, it slides along the X direction along the slide groove. The limiting groove is used to limit its sliding stroke. The elastic element on the buffer block and the elastic element on its left side wall are used to provide buffering force during its sliding process, and drive the moving strip to reset after the external driving force is released.

[0065] Furthermore, on the bottom surface of the movable strip 22, corresponding to the position of the opening and closing hole 213, a drive plate 27 is vertically connected downwards, passing downwards through the opening and closing hole 213. The bottom surface of the drive plate 27 is provided with a ramp surface 271, and the inclination direction of the ramp surface 271 is opposite to that of the lock chamber.

[0066] The lifting and opening module includes a first lifting cylinder 41, a lifting plate 42, a roller bracket 43, and a roller 44, all with the driving direction along the Z direction.

[0067] The fixed part of the first lifting cylinder 41 is installed on the support platform 5. Its drive output end is set upward and fixed to the lifting plate. A roller bracket is fixed to the lifting plate. Two rollers 44 are rotatably connected to the top of the roller bracket. The two rollers are arranged side by side.

[0068] When the positioning fixture 2 rotates with the rotating disk 1 to above the first lifting cylinder 41, the first lifting cylinder 41 drives the two rollers to rise, abut against the inclined surface 271 of the drive plate 27 and generate a horizontal component force, pushing the drive plate 27 and the moving strip 22 to slide in the X direction away from the material bin, and then through the round shaft 251, it drives each pressing plate to move against the elastic force, so that the pressing head is separated from the bearing surface, realizing the automatic unlocking of each material bin in the positioning fixture 2, so as to facilitate the placement of FPC materials or the picking and unloading of materials.

[0069] The first lifting cylinder 41 descends and resets, releasing the lifting force on the drive plate. The moving bar automatically resets under the restoring force of the spring, driving all the pressing heads to reset synchronously, thus restoring the locking state of the positioning fixture.

[0070] After the FPC material is pressed and fixed on the positioning fixture 2, the rotating disk drives the positioning fixture to rotate to the bending module (not shown in the figure) to perform the bending action.

[0071] After the bending operation is completed, the strip portion 001 and its irregularly shaped portion 002 of each FPC material are connected at a specific angle along the preset bending surface, causing the irregularly shaped portion 002 to hang on the outside of the positioning fixture in a downward or oblique downward posture. This posture is not conducive to the subsequent assembly or packaging operations of the FPC material. In order to facilitate the robot arm to stably pick up the surface of the irregularly shaped portion through the suction cup and perform a uniform and orderly unloading operation, the FPC material needs to be flipped so that the irregularly shaped portion of the FPC material is adjusted to a horizontal position or a near-horizontal position.

[0072] The material handling and flipping module 3 includes a material handling translation drive module 31 with the drive direction along the Y direction, a material handling lifting drive module 32 with the drive direction along the Z direction, a rotation drive module, a rotation shaft 35, and several material handling heads 36.

[0073] The rotating shaft 35 includes a rotating rod 351 and a drive gear 352 connected to one end thereto.

[0074] The rotary drive module includes a rack 341 and a rack lifting cylinder 342 with the drive direction along the Z direction.

[0075] The material handling translation drive module 31 is mounted on the support platform 5, and the horizontal plate 37 is connected to its drive output end. The fixing part of the material handling lifting drive module 32 is installed on one end of the horizontal plate 37. One end of the fixing frame is connected to the drive output end of the material handling lifting drive module 32 and moves up and down along the Z direction with the material handling lifting drive module 32. The other end of the fixing frame extends along the X direction to form a support arm 33, and each end of the support arm 33 extends downward to form a lower hanging ear 331.

[0076] Both ends of the rotating rod 351 are rotatably connected to the corresponding lower lugs 331 via bearings, and the drive gear 352 is located outside one of the lower lugs 331. The fixed part of the rack lifting cylinder 342 is mounted on the support arm 33 and on the same side as the drive gear 352. The drive output end of the rack lifting cylinder 342 is connected to the rack 341, which is set along the Z-direction. The gear on the rack 341 meshes with the drive gear 352. When the rack lifting cylinder 342 drives the rack to rise and fall, the rack simultaneously drives the drive gear 352 to rotate, thereby causing the rotating rod 351 to rotate around its central axis.

[0077] The picking heads 36 are installed at intervals on the rotating rod 351, and their number corresponds to the number of material bins on the positioning fixture. In this utility model, a total of four picking heads 36 are provided. When the positioning fixture 2 rotates to the picking and flipping module 3, the positions of the four picking heads 36 correspond one-to-one with the positions of the four material bins on the positioning fixture.

[0078] Each picking head 36 has a vacuum suction cup 361 and a pressing head 362 mounted on its bottom surface facing the positioning fixture. The vacuum suction cup 361 is offset to one side of the bottom surface of the picking head and is used to adsorb the area on the strip section 001 of FPC material that does not have a functional component 003. The pressing head is located on the other side of the picking head, and its bottom surface has a protective groove. When the vacuum suction cup adsorbs FPC material, the pressing head 362 presses over the area of ​​the strip section 001 where the functional component 003 is located, and the functional component is housed in the protective groove to avoid touching the functional component 003 during the picking process.

[0079] During material handling, the material handling translation drive module 31 drives the horizontal plate 37 to move along the Y direction, aligning the material handling head with the material bin on the positioning fixture. Subsequently, the material handling lifting drive module 32 drives the fixed frame and rotating shaft 35 to descend along the Z direction, causing the vacuum suction cups 361 on each material handling head 36 to adhere to the component-free area of ​​the FPC material strip 001. At the same time, the pressing head 362 presses against the strips on both sides of the functional component, and the functional component is accommodated in the protective groove to prevent the thin FPC material from warping during handling.

[0080] After the material is picked up, the rack and pinion lifting cylinder 342 drives the rack 341 to move, which in turn drives the drive gear and rotating rod to rotate by a predetermined angle, so that the irregular part of the FPC material is flipped from a hanging state to a horizontal or near-horizontal state, so as to facilitate the subsequent uniform picking and unloading by the robot.

[0081] Preferably, a flip-limiting plate 332 is provided vertically downward on the support arm 33, away from the positioning fixture. The flip-limiting plate 332 is located above the rotation axis 35 and is spaced from the movement trajectory of the rotating rod at a predetermined rotation angle. When the rotating rod rotates to the predetermined angle (e.g., 90°), it limits the continued rotation of the rotating rod and prevents it from flipping over the limit.

[0082] To further prevent the irregularly shaped parts of the FPC material from swaying due to their overhang after flipping, the material handling and flipping module 3 also includes a material support component.

[0083] The material support assembly includes a material support lifting cylinder 61 and a material support bar 62, which are driven in the Z direction.

[0084] To facilitate the connection of the material support assembly, a guide rail 38 is installed on the support platform 5 along the Y direction. One end of the horizontal plate 37 is connected to the drive conveying end of the material picking and translation drive module 31, and the other end is slidably connected to the guide rail 38. The fixing part of the material support lifting cylinder 61 is installed on the other end of the horizontal plate 37, and its drive output end is connected to the material support bar 62 facing upward. The material support bar 62 is located on the side of the rotating rod away from the positioning fixture. The length of the material support bar 62 extends along the X direction and is parallel to the rotating axis 35.

[0085] After the irregular part of the FPC material is flipped to the horizontal, the support lifting cylinder 61 drives the support bar 62 to rise, supporting the far end of the irregular part of the FPC material and providing auxiliary support to ensure the stability of the robot arm's unloading posture.

[0086] On the support platform 5, there is also a robotic arm 8 for unloading the flipped FPC material.

[0087] The robotic arm 8 has a number of gripper heads 81 as there are material handling heads. Each gripper head 81 is provided with several vacuum suction cups at intervals for adsorbing irregularly shaped parts of FPC materials. In this invention, the robotic arm 8 has a total of four gripper heads 81.

[0088] Once the irregularly shaped part of the FPC material is flipped to a horizontal position, the robot moves to the corresponding station, causing the vacuum suction cups on each gripper head to attach to the surface of the irregularly shaped part of the FPC material, thereby performing the unloading action.

[0089] To further ensure the quality of material feeding, the support platform 5 is also equipped with a feeding re-inspection module 7, which is used to visually inspect the FPC materials held by the robotic arm. This feeding re-inspection module 7 captures images of the FPC materials, compares the obtained images with preset template images, and then converts the judgment results into control signals and sends them to the control mechanism (not shown). Based on the signals, the control mechanism controls the robotic arm to move the FPC materials that are judged to be unqualified to the NG warehouse, and moves the qualified FPC materials to the next workstation or the finished product packaging area.

[0090] The material unloading re-inspection module 7 includes a re-inspection linear drive module 71, a CCD module 72 connected to its drive output end, and a light source 73 coaxially arranged with the CCD module's imaging lens. The re-inspection linear drive module 71 is used to drive the CCD module and the light source to move, so as to realize the sequential or synchronous photographing and inspection of all FPC materials on the robot arm.

[0091] The material handling translation drive module 31, the material handling lifting drive module 32, and the re-inspection linear drive module 71 are all commercially available KK linear motion drive modules.

[0092] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
