Description

Technical Field

[0001] This utility model belongs to the field of FPC processing technology, and specifically refers to a mechanism for flipping FPC. Background Technology

[0002] FPC stands for Flexible Printed Circuit Board, a type of circuit board made using a flexible insulating substrate. Compared to traditional rigid circuit boards, FPCs can be bent and folded, making them widely used in electronic products that require space constraints or flexibility, such as mobile phones, tablets, and other portable devices.

[0003] In the FPC processing flow, it may be necessary to perform operations such as inkjet printing and inspection on both sides. In the current technology, the flipping action of FPC is performed manually, which is not automated enough and has problems such as low production efficiency. Utility Model Content

[0004] The main purpose of this invention is to provide a mechanism for flipping FPCs, which solves the problems existing in the prior art and enables automatic flipping of FPCs.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A mechanism for flipping an FPC includes a frame and two sets of flipping manipulators. The two sets of manipulators move horizontally in opposite directions or away from each other along the frame. Each flipping manipulator includes a sliding seat that slides with the frame, a lifting seat that lifts below the sliding seat, a flipping drive device mounted below the lifting seat, a suction cup bracket mounted at the output end of the flipping drive device, and a plurality of suction cups mounted on the suction cup bracket. The suction cups are used to pick up the FPC. When the suction cup bracket of the flipping manipulator flips, the FPC is in a horizontal or vertical state. When the FPC is in a vertical state, the suction cups of the two sets of flipping manipulators engage with the front and back sides of the FPC respectively, so that the FPC is transferred from one flipping manipulator to the other.

[0007] Guide rails are provided on both sides of the frame, and sliders that slide on the guide rails are provided on both sides of the sliding seat.

[0008] Preferably, a belt conveyor is provided on each side of the frame, and a clamping member is provided on the sliding seat to hold the belt of the belt conveyor.

[0009] The sliding seat is equipped with a first cylinder for driving the lifting seat, and the output rod of the first cylinder passes through the sliding seat and is connected to the lifting seat.

[0010] Preferably, guide columns are vertically connected to the four corners of the lifting seat, and guide sleeves are provided on the sliding seat for the guide columns to move through.

[0011] The flipping drive device includes a second cylinder whose upper end is fixedly connected to the lifting seat, a flipping bracket fixedly connected to the lower end of the second cylinder, and a flipping block fixedly connected to the suction cup bracket; the flipping block is pivotally connected to the flipping bracket, and the output end of the second cylinder moves against the flipping block to make it swing around the rotation axis of the flipping block.

[0012] Both sides of the suction cup bracket are fixed with a first profile, and several second profiles are installed on the first profile in an adjustable position. The suction cup is fixed below the outer end of the second profile. The first profile and the second profile are perpendicular to each other and locked together by hand-tightening bolts.

[0013] After adopting the above technical solution, the present invention has the following technical effects:

[0014] This utility model, through the cooperation of two sets of robotic arms, can realize the following: "one robotic arm picks up the FPC from the fixture → flips the FPC → transfers it to the other robotic arm → flips the FPC again → places the FPC on the fixture", thereby automatically flipping the FPC 180° (i.e., turning it over). It can be used in conjunction with other devices of the processing equipment to process both sides of the FPC to meet production needs. Attached Figure Description

Detailed Implementation

[0022] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0023] refer to Figure 1-4 As shown, this utility model discloses a mechanism for flipping FPC, including a frame 1 and two sets of flipping manipulators 2 and 2'. The two sets of manipulators 2 and 2' move horizontally towards each other or away from each other along the horizontal direction on the frame 1.

[0024] The flipping robot 2 includes a sliding seat 21 that slides with the frame 1, a lifting seat 22 that lifts and lowers below the sliding seat 21, a flipping drive device 23 installed below the lifting seat 22, a suction cup bracket 24 installed at the output end of the flipping drive device 23, and a plurality of suction cups 25 installed on the suction cup bracket 24. The suction cups 25 are used to adsorb FPC.

[0025] When the suction cup bracket 24 of the flipping robot 2 flips the FPC, it makes the FPC horizontal or vertical. When the FPC is vertical, the suction cups 25 and 25' of the two sets of flipping robots 2 and 2' are respectively engaged on the front and back of the FPC, so that the FPC is transferred from one flipping robot 2 to the other flipping robot 2'.

[0026] Through the above scheme, this utility model, by cooperating with two sets of robotic arms 2 and 2', can realize "one robotic arm 2 picks up the FPC from the fixture → flips the FPC → transfers it to another robotic arm 2' → flips the FPC again → places the FPC on the fixture", thereby automatically flipping the FPC 180° (i.e., turning it over). It can be used in conjunction with other devices of the processing equipment to process both sides of the FPC, thus meeting production needs.

[0027] The following are specific embodiments of the present invention.

[0028] Guide rails 11 are provided on both sides of the frame 1, and sliders 211 that slide on the guide rails 11 are provided on both sides of the sliding base 21. The two sets of flipping manipulators 2 and 2' can be guided to move simultaneously through a pair of guide rails 11, and the stability of the movement direction and force is ensured.

[0029] Furthermore, a belt conveyor 12 is respectively installed on both sides of the frame 1, and a clamping member 212 is installed on the sliding seat 21 to hold the belt of the belt conveyor 12. Thus, the two belt conveyors 12 drive the two sets of robotic arms 2 and 2' to move horizontally along the guide rail 11. In this embodiment, the belt conveyor 12 is driven by a stepper motor 13, which can precisely control the moving distance of the flipping robotic arm 2.

[0030] The sliding seat 21 is equipped with a first cylinder 26 for driving the lifting seat 22. The output rod of the first cylinder 26 passes through the sliding seat 21 and is connected to the lifting seat 22.

[0031] Furthermore, guide posts 221 are vertically connected to the four corners of the lifting seat 22, and guide sleeves 213 are provided on the sliding seat 21 for the guide posts 221 to move through, thereby realizing the movement guidance of the lifting seat 22.

[0032] The aforementioned flipping drive device 23 includes a second cylinder 231 whose upper end is fixedly connected to the lifting seat 22, a flipping bracket 232 fixedly connected to the lower end of the second cylinder 231, and a flipping block 233 fixedly connected to the suction cup bracket 24. The flipping block 233 is pivotally connected to the flipping bracket 232, and the output end of the second cylinder 231 moves against the flipping block 233 to make it swing around the rotation axis of the flipping block 233, thereby driving the suction cup bracket 24 to swing.

[0033] The suction cup bracket 24 is fixed with a first profile 241 on both sides. Several second profiles 242 are installed on the first profile 241 in an adjustable position. The suction cup 25 is fixed below the outer end of the second profile 242, so that the position of the suction cup 25 can be adjusted. The first profile 241 and the second profile 242 are perpendicular to each other and locked by a hand-tightening bolt 243.

[0034] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
