Description

Technical Field

[0001] This invention relates to the field of FPC flexible circuit board processing, and more particularly to a synchronous processing mechanism for FPC flexible circuit boards. Background Technology

[0002] Flexible printed circuit boards (FPCs) are highly reliable and extremely flexible printed circuit boards made with polyimide or polyester film as the substrate. They are characterized by high wiring density, light weight, thinness, and good bendability. When assembling FPCs, pre-bending and positioning are required to locate the bending part of the product and form a crease at the bending point. Then, the release film on the tape on the part of the product to be bent is removed. Finally, the product with the exposed tape is bent and bonded to complete the processing.

[0003] In existing technologies, the pre-bending, film peeling, and bending of FPC flexible circuit boards need to be carried out step by step at different workstations, resulting in low processing efficiency. Furthermore, existing FPC flexible circuit board bending processes primarily utilize fixtures to improve processing accuracy. For example, the invention patent with authorization announcement number CN2213951680U, entitled "FPC Multi-Pass Bending Processing Fixture," includes a base with a guide groove on its front side. Several pressure plates are movably fixed on the front side of the base to press the FPC into the guide groove. The FPC is bent and positioned using the guide groove and the pressure plates, reducing the offset caused by simple manual bending. However, due to the inherent characteristics of the FPC flexible material, the workpiece is prone to springback when the bending force is insufficient. Additionally, manual operation of the fixture has a large error rate, and only one process can be performed on one workpiece at a time, resulting in low efficiency, low yield, and inability to meet the needs of large-scale, high-precision production.

[0004] To improve efficiency, enhance the accuracy of FPC (Flexible Printed Circuit) bending, and prevent workpiece springback from exceeding tolerances, existing improvements involve providing multiple bending stations and using pneumatic or electric methods to complete product bending. For example, the invention patent with authorization announcement number CN103230968B, entitled "A Pneumatic Bending Device for FPC," uses multiple grooves matching the product shape and corresponding pressure blocks on these grooves. A cylinder drives the pressure blocks downwards to simultaneously bend multiple products. However, this equipment can only complete the bending process; pre-bending and film-removing processes before bending are required separately. Furthermore, existing processing devices require sequential loading and unloading, making simultaneous loading and unloading impossible. Summary of the Invention

[0005] Therefore, in order to solve the above problems, the present invention provides a synchronous processing mechanism for FPC flexible circuit boards.

[0006] This invention is achieved through the following technical solution:

[0007] A synchronous processing mechanism for flexible printed circuit boards (FPCs) includes an operating table and a synchronous transfer mechanism movably mounted on top of the operating table. A first guide rail is provided on one side of the operating table along the X-axis, and a loading platform is movably mounted on the guide rail. A pre-bending station, a film-tearing station, a bending station, and a unloading platform are sequentially arranged on one side of the loading platform along the X-axis. The synchronous transfer mechanism includes an X-axis module positioned above the operating table along the X-axis, and a frame is movably mounted on the X-axis module. A first robotic arm, a second robotic arm, and a third robotic arm are fixedly mounted at equal intervals at the bottom of the frame. A fourth robotic arm is retractably mounted along the X-axis on the side of the frame near the unloading platform. Each robotic arm includes a Z-axis module positioned along the Z-axis and a carrier plate that moves vertically along the Z-axis module. A vacuum suction head for adsorbing workpieces is provided at the bottom of the carrier plate.

[0008] Preferably, the spacing between the carrier plates at the bottom of two adjacent robotic arms is the same as the spacing between two adjacent processing stations, and the width of each processing station is the same.

[0009] Preferably, each processing station has a vacuum adsorption hole for adsorbing the workpiece body and a limiting block for positioning the workpiece by passing through the gap between the workpiece bodies.

[0010] Preferably, each processing station is provided with a positioning groove for positioning the workpiece. The vacuum suction hole and the limiting block are disposed in the positioning groove. The first end of the positioning groove is provided with a first end positioning groove for placing the end of the workpiece. Each processing station is provided with a processing component at the end where the first end positioning groove is located. The loading platform and unloading platform are provided with multiple storage stations. The width of the storage station is the same as the width of the processing station. Each storage station is provided with a limiting block for positioning the workpiece by passing through the gap between the main bodies of each workpiece. Each storage station is also provided with a positioning groove for positioning the workpiece.

[0011] Preferably, the distance between the unloading platform and the bending station is the same as the distance between two adjacent processing stations, the distance between two adjacent processing stations is the width of n processing stations, the loading platform and the unloading platform are provided with n+1 storage stations, and the longest distance between the carrier plate at the bottom of the fourth robotic arm and the carrier plate at the bottom of the third robotic arm is the width of 2n processing stations.

[0012] Preferably, the processing component of the pre-bending station includes a pressing mechanism disposed on its top, a pressing block for pre-bending the workpiece is disposed at the bottom of the pressing mechanism, and a pressing head for setting indentations on the workpiece surface is disposed at the bottom of the pressing block, the pressing head having a sharp corner at the bottom.

[0013] Preferably, the pressing mechanism is movably mounted on the lifting platform, and the lifting platform reciprocates along the third guide rail on the operating platform in the Y-axis direction.

[0014] Preferably, the processing component of the film-tearing station includes a clamp disposed at one end for film tearing, and the film-tearing station is provided with a clearance hole for the clamp to pass through. The clamp is vertically and flexibly disposed in the clearance hole by a cylinder.

[0015] Preferably, the processing component of the bending station includes a mounting groove at one end, in which a flipping arm for bending the workpiece is provided. The flipping arm is driven by a flipping motor to rotate along a flipping axis, which is coaxial with the crease of the workpiece. The flipping arm is provided with a vacuum adsorption hole for adsorbing the workpiece.

[0016] Preferably, each processing station and storage station is further provided with a second terminal positioning groove of a different shape from the first terminal positioning groove at its second end, and each station is also provided with a set of processing components at one end of the second terminal positioning groove.

[0017] The beneficial effects of the technical solution of this invention are mainly reflected in:

[0018] 1. By utilizing the synchronous transfer mechanism and the various workstations and loading platforms on the operating table, multiple workstations and multiple processes can be carried out simultaneously, as well as the synchronous handling of multiple workstations on multiple workstations, thereby improving production efficiency. Each workstation on the operating table synchronously realizes the various processes of loading, pre-bending, film peeling, bending and unloading, realizing the complete processing of FPC flexible circuit boards. At the same time, multiple material storage workstations are set up on the loading and unloading platforms, which can replace the loading and unloading platforms after multiple loading and unloading operations.

[0019] 2. The loading platform moves along the guide rail in the X-axis direction. The fourth robotic arm on the synchronous transfer mechanism is telescopically mounted on one side of the frame in the X-axis direction. The loading platform and unloading platform are respectively equipped with multiple positioning slots for carrying workpieces, so multiple workpieces can be loaded and unloaded synchronously, further improving processing efficiency.

[0020] 3. Each workstation is equipped with a positioning groove that matches the shape of the workpiece, and a vacuum adsorption hole is set in the positioning groove. During processing, the positioning groove and the vacuum adsorption hole are used to position the workpiece simultaneously, thereby avoiding errors caused by workpiece offset and improving processing accuracy.

Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0038] In this invention, "multiple" means two or more, unless otherwise explicitly specified.

[0039] This invention discloses a synchronous processing mechanism for FPC flexible circuit boards, used to bend FPC flexible circuit board workpiece 100, such as... Figure 1 As shown, the FPC flexible circuit board workpiece 100 to be processed includes multiple workpiece bodies 1001 arranged in parallel, with gaps 1002 formed between each workpiece body 1001. Solder parts 1003 are disposed between adjacent workpiece bodies 1001 through the gaps 1002 to achieve connection and conductivity between the workpiece bodies 1001. One end of each workpiece body 1001 is provided with a workpiece end 1004, and a bending area 1005 is provided on one side of the workpiece end 1004. The FPC flexible circuit board synchronous processing mechanism disclosed in this invention is used to process the workpiece... The bending area 1005 of the end 1004 is bent and fixed. After bending, a crease 1006 will be generated at the bending position of the bending area 1005 of the workpiece end 1004. To determine the bending position of the workpiece, it is usually necessary to press out the crease 1006 first. After bending, the bending area 1005 is attached to the other side of the workpiece end 1002 with tape. Before bending the workpiece, the release film 1007 on the tape is removed. Then the bending area 1005 is bent and covered to the other side of the workpiece end 1004, and attached to the other side of the workpiece end 1004 with tape.

[0040] like Figures 2-8As shown, the FPC flexible circuit board synchronous processing mechanism includes an operating table 1 and a synchronous transfer mechanism 2 movably disposed on the top of the operating table 1. The operating table is sequentially arranged along the X-axis direction with a loading platform 4, a pre-bending station 5, a film-peeling station 6, a bending station 7, and a unloading platform 8 (the X-axis direction is the conveying direction of the workpiece from loading to unloading, the Y-axis direction is the length direction of each station, and the Z-axis direction is the height direction). The synchronous transfer mechanism 2 includes components disposed along the X-axis direction on the operating table. The X-axis module 9 is located above the X-axis module 1. A frame 3 is movably mounted on the X-axis module 9. Specifically, a first slider 10 is movably mounted on the bottom of the X-axis module 9 along its two side rails via a first cylinder. The frame 3 is located at the bottom of the first slider 10 and moves along the X-axis module 9 with the first slider 10. A first robotic arm 11, a second robotic arm 12, and a third robotic arm 13 are fixedly mounted at equal intervals at the bottom of the frame 3. A telescopic mechanism is provided on the side of the frame 3 near the unloading platform. A fourth robotic arm 14 is reciprocating along the X-axis on the telescopic mechanism. Specifically, the telescopic mechanism includes a second guide rail 1501 arranged along the X-axis on one side of the frame 3. The second guide rail 1501 consists of two symmetrically arranged guide rails, with a linear motor between the two guide rails. Each guide rail has a second slider, and a telescopic frame 15 is fixedly mounted on the second slider. Specifically, the two sides of the telescopic frame are respectively connected to the second sliders on the two second guide rails, and the bottom of the telescopic frame is connected to the linear motor. The fourth robotic arm 14 is located at the bottom of the telescopic frame 15. The telescopic frame is driven by the linear motor to translate along the second guide rail 1501 in the X-axis direction, and drives the fourth robotic arm 14 to reciprocate along the X-axis on one side of the frame 3. The first robotic arm 11, the second robotic arm 12, the third robotic arm 13, and the fourth robotic arm 14 translate synchronously with the frame 3 along the X-axis direction. In addition, the fourth robotic arm 14 can also translate independently along the second guide rail 1501 in the X-axis direction.

[0041] An initial workstation is provided on the operating table 1. A first guide rail 401 is provided on one side of the operating table 1 along the X-axis. The loading platform 4 is movably mounted on the first guide rail 401. The loading platform moves synchronously with the frame 3 and the two move the same distance. Multiple storage workstations are sequentially arranged on the loading platform along the X-axis. After each movement of the loading platform, only one storage workstation is located on the initial workstation. Specifically, the initial workstation is used to define the position of the loaded workpiece. Since multiple storage workstations are provided on the loading platform, after each material retrieval, the loading platform moves synchronously with the frame, sequentially moving the storage workstation containing the workpiece to be processed to the initial workstation. When the first robotic arm 3 retrieves the material, it moves to directly above the initial workstation along with the frame 3. Therefore, the workpiece to be processed placed on the storage workstation at the initial workstation is just picked up by the first robotic arm.

[0042] Each robotic arm includes a carrier plate 16 and a lifting cylinder that drives the carrier plate 16 to move up and down along the Z-axis. The carrier plate 16 is located at the bottom of the lifting cylinder. Specifically, a third slider is provided along the guide rail on one side of the Z-axis module, and the carrier plate 16 is located at the bottom of the third slider. The third slider is driven by the third cylinder to move the carrier plate 16 up and down on the Z-axis module. Guide rods 1601 are respectively provided at the top of both ends of each carrier plate 16. The frame 3 is provided with guide sleeves 301 that match the position and number of the guide rods 1601. When the carrier plate 16 moves along the Z-axis module with the third slider, the guide rods 1601 move up and down within the guide sleeves 301 to ensure the stability of the carrier plate 16 during the lifting process. The bottom of the carrier plate 16 is provided with... A vacuum suction head is provided for adsorbing workpieces. Specifically, the carrier plate 16 includes a carrier plate 16 body for gripping the workpiece body 1001 and a carrier plate 16 pressure head 1802 disposed at one end of the carrier plate 16 body and matching the workpiece end 1004. Vacuum suction heads are provided on both the carrier plate 16 body and the carrier plate 16 pressure head 1802. The vacuum suction heads on the carrier plate 16 body are arranged according to the position of the workpiece body 1001, and the vacuum suction heads on the carrier plate 16 pressure head 1802 are arranged according to the position of the workpiece end 1004. When the carrier plate 16 picks up the workpiece, the vacuum suction heads on the carrier plate 16 body are in contact with the upper surface of the workpiece body 1001, and the vacuum suction heads on the carrier plate 16 pressure head 1802 are in contact with the upper surface of the carrier plate 16 pressure head 1802.

[0043] The spacing between the carrier plates 16 at the bottom of two adjacent robotic arms (including the initial / shortest distance between the fourth robotic arm 14 and the third robotic arm 13) is the same as the spacing between two adjacent processing stations. The distance between the initial station and the pre-bending station 5 is the same as the spacing between two adjacent processing stations. The width of each processing station (i.e., the pre-bending station 5, the film-tearing station 6, and the bending station 7) is the same. The width of the material storage station is the same as the width of the processing station. Each robotic arm moves between two processing stations / platforms. Specifically, the first robotic arm 11 moves between the loading platform. The first robotic arm 4 moves between the loading platform 4 and the pre-bending station 5 to transport the workpiece on the loading platform 4 to the pre-bending station 5; the second robotic arm 12 moves between the pre-bending station 5 and the film-tearing station 6 to transport the workpiece that has completed the pre-bending process on the pre-bending station 5 to the film-tearing station 6; the third robotic arm 13 moves between the film-tearing station 6 and the bending station 7 to transport the workpiece after the release film 1007 has been removed on the film-tearing station 6 to the bending station 7; the fourth robotic arm 14 moves between the bending station 7 and the unloading platform 8 to transport the workpiece after bending to the unloading platform 8.

[0044] Each processing station is provided with a vacuum adsorption hole 21 for adsorbing the workpiece body 1001. The arrangement of the vacuum adsorption holes 21 corresponds to the location of the workpiece body 1001, and the vacuum adsorption holes 21 should avoid the gaps 1002 between each workpiece body 1001 and the location of the through holes on the workpiece body 1001.

[0045] In a preferred embodiment, each processing station is provided with a positioning groove for positioning the workpiece. Each processing station has one and only one positioning groove. During processing, the workpiece is fixed in the positioning groove to prevent errors caused by workpiece displacement. To further enhance the positioning effect, the vacuum adsorption hole 21 and the limiting block 20 are provided in the positioning groove. When the workpiece is placed in the positioning groove, the lower surface of the workpiece body 1001 is vacuumed through the vacuum adsorption hole 21 and tightly adheres to the surface of the positioning groove. The positioning groove is also provided with a limiting block 20 for positioning the workpiece by passing through the gap 1002 between each workpiece body 1001. The arrangement position of the limiting block 20 corresponds to the gap 1002 between each workpiece body 1001. Therefore, when the workpiece is placed in the positioning groove, the limiting block 20 positions the workpiece by passing through the gap 1002 between each workpiece body 1001.

[0046] Each positioning groove has a first end positioning groove 19 at its first end for placing the workpiece end 1004. The shape of the first end positioning groove 19 matches the shape of the workpiece end 1004. Each processing station has a set of processing components at one end of the first end positioning groove 19 for processing the bending area 1005 of the workpiece end 1004 for the process performed at that station.

[0047] The unloading platform 8 is also equipped with multiple storage stations, the width of which is the same as the width of the processing station. Each storage station is equipped with a limiting block 20 for positioning the workpiece by passing through the gap 1002 between the main bodies 1001 of each workpiece. Each storage station also has a positioning groove for positioning the workpiece. The vacuum suction hole 21 and the limiting block 20 are located within the positioning groove. Since the initial distance between the fourth robotic arm 14 and the third robotic arm 13 is the same as the interval between two adjacent processing stations, the telescopic frame... Without moving, the fourth robotic arm 14 is located directly above the storage station closest to the bending station on the unloading platform. Each time the telescopic frame unloads material (except for the first unloading), the extension length is increased by the width of one storage station compared to the extension length of the previous unloading, thereby ensuring that the fourth robotic arm unloads and loads material sequentially at different storage stations on the unloading platform. The fourth robotic arm retracts each time it picks up material, ensuring that the fourth robotic arm 14 and the third robotic arm 13 maintain the initial distance when picking up material, so that the fourth robotic arm 14 is located directly above the bending station when picking up material.

[0048] In a preferred embodiment, each positioning groove is further provided with a second terminal positioning groove at its second end for placing workpiece terminals of a different shape than the first terminal positioning groove. Each processing station is also provided with a set of processing components at one end of the second terminal positioning groove. Specifically, in practical applications, there are two or more different types of FPC flexible circuit board workpieces 100. The shape and arrangement of the workpiece body 1001 in different types of FPC flexible circuit board workpieces 100 are the same, but the shapes of the workpiece terminals are not the same. In order to adapt to the processing of different types of FPC flexible circuit board workpieces 100, a second terminal positioning groove matching the shape of the workpiece terminals of other types of FPC flexible circuit board workpieces 100 is provided at the second end of the positioning groove of each processing station and platform. Therefore, during transportation and processing, the placement directions of FPC flexible circuit board workpieces 100 whose workpiece terminal shape matches the first terminal positioning groove and FPC flexible circuit board workpieces 100 whose workpiece terminals match the second terminal positioning groove are opposite.

[0049] In a preferred embodiment, the distance between two adjacent processing stations is the width of n (n is a natural number ≥ 1) processing stations. The loading platform 4 and unloading platform 8 are provided with n+1 storage stations. When the four robotic arms synchronously move along the frame 3 to pick up parts, the carrier plate 16 at the bottom of the first robotic arm 11 grasps the workpieces at different storage stations on the loading platform 4 as the loading platform 4 moves. When the four robotic arms synchronously move along the frame 3 to place parts, the carrier plate 16 at the bottom of the fourth robotic arm 14 places the processed workpieces at different storage stations on the unloading platform 8 as the fourth robotic arm 14 extends and retracts. For example, when n When =1, the distance between two adjacent processing stations is the width of one processing station, and the distance between the carrier plates 16 at the bottom of two adjacent robotic arms is the width of one processing station. The initial / shortest distance between the fourth robotic arm 14 and the third robotic arm 13 is the width of one processing station. Two storage stations are respectively set on the loading platform 4 and the unloading platform 8. At this time, when the four robotic arms synchronously move to retrieve parts from the frame 3, if the loading platform 4 is close to the pre-bending station 5, then a storage station on the loading platform 4 away from the pre-bending station 5 is set directly below the first robotic arm 11. When the first robotic arm 11 removes the storage station... After the workpiece is removed from the material handling station, the loading platform 4 moves along the first guide rail 401 a distance away from the pre-bending station 5 by one processing station. Therefore, when the first robotic arm 11 picks up the workpiece for the second time, a storage station near the pre-bending station 5 is set directly below the first robotic arm 11. Similarly, in subsequent material handling processes, when n>1, by controlling the interval between the loading platform 4 and the pre-bending station 5, it is ensured that the first robotic arm 11 picks up all the workpieces on the loading platform 4 in sequence. When the four robotic arms synchronously move and place the workpieces on the frame 3, the fourth robotic arm 14 is exactly set directly below a storage station near the bending station 7 on the unloading platform 8. Above, the fourth robotic arm 14 first places the processed workpiece on the storage station. After the second material retrieval, the fourth robotic arm 14 moves along the second guide rail 1501 to the side away from the third robotic arm 13 by a distance of one processing station. During the second material unloading, the fourth robotic arm 14 is positioned directly above the storage station on the unloading platform 8 on the side away from the bending station 7. Similarly, in the subsequent material retrieval process, when n>1, by controlling the distance between the fourth robotic arm 14 and the third robotic arm 13, it is ensured that the fourth robotic arm 14 sequentially places the processed workpiece on each storage station on the unloading platform 8.

[0050] The distance between the unloading platform 8 and the bending station 7 is the same as the distance between two adjacent processing stations. Since the distance between two adjacent processing stations is n, and the unloading platform 8 is provided with n+1 storage stations, when the carrier plate 16 at the bottom of the fourth robotic arm 14 is positioned directly above the storage station on the unloading platform 8 that is furthest from the bending station 7, the distance between the fourth robotic arm 14 and the third robotic arm 13 reaches its maximum. At this time, the maximum distance between the carrier plate 16 at the bottom of the fourth robotic arm 14 and the carrier plate 16 at the bottom of the third robotic arm 13 is the width of 2n processing stations.

[0051] In some other embodiments, the distance between the unloading platform 8 and the bending station 7 may be greater than or less than the distance between two adjacent processing stations. In some embodiments, positioning sensors, such as photoelectric sensors, are provided on the unloading platform 8 and the fourth robotic arm 14. The positions of the upper plate 16 on the fourth robotic arm 14 and the storage station on the unloading platform 8 are determined by the positioning sensors. By controlling the distance between the fourth robotic arm 14 and the third robotic arm 13, it is ensured that the fourth robotic arm 14 sequentially places the processed workpieces on each storage station on the unloading platform 8.

[0052] like Figure 9 , Figure 10 As shown, the processing assembly of the pre-bending station 5 includes a pressing mechanism 18 disposed on its top. The pressing mechanism 18 is vertically and flexibly disposed on a lifting platform 17. The lifting platform 17 reciprocates along a third guide rail 1702 disposed on the operating table 1 in the Y-axis direction. The bottom of the pressing mechanism 18 is provided with a pressing block 1801 for pre-bending the workpiece. The bottom of the pressing block 1801 is also provided with a pressing head 1802 for setting indentations on the surface of the workpiece. The bottom of the pressing head 1802 is provided with a sharp corner 1803. The sharp corner 1803 is generally triangular prism-shaped and its bottom narrows. Specifically, the lifting platform 17 is provided with... The second lifting cylinder 1701 drives the pressing mechanism 18, which is movably mounted on the lifting platform 17. The lifting platform 17 moves the pressing mechanism 18 to the top of the first end positioning groove 19 by translating on the third guide rail 1702. When the lifting platform 17 moves into position on the third guide rail 1702, the sharp corner 1803 of the pressing head 1802 is located at the bending position of the workpiece end 1004 in the bending area 1005. The second lifting cylinder 1701 drives the pressing mechanism 18 to descend and leaves an indentation at the bending position of the workpiece through the sharp corner 1803. The indentation is a straight line.

[0053] like Figure 11 , Figure 12As shown, the processing assembly of the film-tearing station 6 includes a clamp 602 disposed at one end for film tearing. The film-tearing station 6 is provided with a clearance hole 601 for the clamp 602 to pass through. Specifically, the clearance hole 601 is disposed at one end of the first end positioning groove 19. When the clamp 602 is disposed in the clearance hole 601 and the clamping position of the clamp 602 is at the same height as the workpiece, the release film 1007 on the surface of the workpiece is exactly located within the clamping position of the clamp 602. The clamp 602 includes an upper clamping plate 6021 and a lower clamping plate 6022 arranged in parallel and driven by different cylinders to move horizontally in the height direction. The clamp 602 opens and closes by controlling the lifting height of the upper clamping plate 6021 and the lower clamping plate 6022. The entire clamp 602 (including the upper clamping plate 6021 and the lower clamping plate 6022) is vertically and flexibly positioned within the clearance hole 601 under cylinder control. When the carrier plate 16 is loading or unloading material, the clamp... The clamp 602 descends to the bottom of the clearance hole 601 to avoid the carrier plate 16. When the release film 1007 needs to be removed, the clamp 602 rises and opens, so that the release film 1007 on the surface of the workpiece is exactly within the clamping position of the clamp 602. Then the clamp 602 closes to clamp the release film 1007. After that, the clamp 602 continues to rise slowly to tear the release film 1007. In a preferred embodiment, the clamp 602 can also be moved along the Y-axis by a cylinder to adjust the position of the clamp 602 clamping the release film 1007. In some embodiments, a positioning block 603 is also provided on one side of the film tearing station 6. The positioning block 603 is rotatably provided on one side of the film tearing station 6 along a rotating shaft 604. After the FPC flexible circuit board workpiece 100 is placed on the film tearing station 6, the positioning block 603 rotates along the rotating shaft 604 and presses against the surface of the film tearing station 6 to prevent the workpiece from shifting during the film tearing process.

[0054] As shown in Figures 13 and 14, the processing component of the bending station 7 includes a mounting groove 704 at one end. The mounting groove 704 is located on one side of the first end positioning groove 19 of the bending station 7. A flipping arm 701 for bending the workpiece is provided in the mounting groove 704. A positioning pin for positioning the workpiece crease 1006 is also provided in the mounting groove 704 and is driven by a cylinder to move along the Y-axis. When the positioning pin moves into position, it is located directly above the indentation at the bending position of the workpiece. Specifically, the flipping arm 701 is driven to rotate by a rotary cylinder 702. The flipping axis 604 of the flipping arm 701 is coaxial with the positioning pin. Therefore, the flipping arm 701 is coaxial with the crease 1006 on the workpiece. When the workpiece is placed in the positioning groove on the bending station 7, the part of the workpiece to be bent is located on the surface of the flipping arm 701. The shape of the flipping arm 701 matches the shape of the part of the workpiece to be bent, and its surface is provided with vacuum adsorption holes 21 for adsorbing the part of the workpiece to be bent. During the operation, the carrier plate 16 first places the workpiece into the positioning groove of the bending station 7. The rotating arm 701 and the vacuum adsorption hole 21 in the positioning groove are activated for vacuum adsorption. Then, the positioning pin moves into place and presses against the crease 1006 surface of the workpiece. Afterward, the rotary cylinder 702 drives the rotating arm 701 to rotate and bend the part of the workpiece to be bent, covering the top of the tape. The rotating arm 701 rotates and presses the part of the workpiece to be bent to ensure that the workpiece is in place. Then, the positioning pin and the rotating arm 701 are reset, and the carrier plate 16 completes the processing. The workpiece is taken away and placed on a workstation on the unloading platform 8. In a preferred embodiment, a positioning element 703 is movably provided on one side of the bending workstation 7 along the X-axis direction by a cylinder. The positioning element 703 moves along an X-axis slide rail set on the operating table, and the positioning element 703 is raised and lowered by a cylinder. When the positioning element 703 moves into position, the cylinder drives the positioning element 703 to descend, so that the positioning element 703 presses precisely on the upper surface of the workpiece, ensuring that the workpiece does not shift during the bending process.
