[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, and thinness.

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0026] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0027] like Figures 1-3 As shown, an automatic FPC board printing and processing feeding mechanism according to an embodiment of the present invention includes a worktable 101, and support legs 102 and a rear side plate 103 fixed at both ends of the worktable 101. The mechanism is characterized by further comprising:

[0028] The workbench 101 is fixed with an FPC board stacking rack 104 and a guide column 106. The FPC board stacking rack 104 is rotatably connected with a cabinet door 105. The guide column 106 is slidably connected with a lifting support plate 107, which is located inside the stacking rack 104. The lifting support plate 107 is provided with a bearing plate 108.

[0029] The transfer assembly 2 is used to grip and move the FPC board. Two sets of the transfer assembly 2 are provided, and both sets of the transfer assembly 2 are provided on the rear side plate 103.

[0030] The calibration component 3 is used to push and calibrate the FPC board, and the calibration component 3 is set on the workbench 101;

[0031] The descent restriction component 4 is used to restrict the downward movement of the lifting support plate 107, and the descent restriction component 4 is disposed on the lifting support plate 107.

[0032] The climbing mechanism 5 moves the lifting support plate 107 upward by grabbing the FPC board through the transfer component 2. The climbing mechanism 5 is installed on the lifting support plate 107.

[0033] In this embodiment of the invention, during use, the worker places the FPC board on the carrier plate 108 and then closes the cabinet door 105. The transfer component 2 on the left grabs the FPC board on the carrier plate 108 and transfers it to the calibration component 3. The calibration component 3 pushes and calibrates the FPC board. The transfer component 2 on the right then sends the calibrated FPC board to the printing machine, improving the feeding accuracy. At the same time, after the transfer component 2 on the left grabs the FPC board on the carrier plate 108, the climbing mechanism 5 drives the lifting support plate 107 to move upward. The lifting support plate 107 drives the carrier plate 108 to move upward, so that the carrier plate 108 automatically moves upward after each FPC board is grabbed, so that the transfer component 2 grabs the FPC board at the same height each time, which facilitates the transfer component 2 to grab the FPC board and realizes automatic feeding of FPC boards, reducing manual operation and improving the feeding accuracy. The worker only needs to add multiple FPC boards to the carrier plate 108 at one time when there is a shortage of material.

[0034] like Figure 1 and Figure 2As shown, in a preferred embodiment of the present invention, the transfer assembly 2 includes a lead screw 202, a sliding block 203, a cylinder 204, a guide sleeve 205, a guide shaft 206, a transfer plate 207, and a suction cup 208. A guide groove 201 is provided on the worktable 101. The sliding block 203 is slidably connected within the guide groove 201. The lead screw 202 is rotatably connected within the guide groove 201, and the lead screw 202 is threadedly engaged with the sliding block 203. The cylinder 204 is fixed to the sliding block 203, and the telescopic end of the cylinder 204 is connected to the transfer plate 207. The suction cup 208 is fixed to the transfer plate 207. The guide sleeve 205 is fixed to the sliding block 203. The guide shaft 206 is on the transfer plate 207, and the guide shaft 206 is slidably connected within the guide sleeve 205.

[0035] In this embodiment of the invention, the suction cup 208 is connected to a negative pressure pump via an air pipe and a solenoid valve. The solenoid valve controls whether the suction cup 208 is connected to the negative pressure pump. When the suction cup 208 is connected to the negative pressure pump, it generates suction. When the solenoid valve controls the suction cup 208 to be disconnected from the negative pressure pump, outside air enters the suction cup 208 through the solenoid valve, breaking the vacuum in the suction cup 208. Next, the lead screw 202 is driven to rotate by a servo motor. The cylinder 204 extends and drives the transfer plate 207 to move downwards. The transfer plate 207 causes the suction cup 208 to contact the FPC plate, creating a moving pressing force between the suction cup 208 and the FPC plate, thereby ensuring that the suction cup 208 can contact the FPC plate. When the PC board is in full contact, the solenoid valve controls the suction cup 208 to connect with the negative pressure pump, and the suction cup 208 picks up the FPC board. The cylinder 204 retracts and drives the FPC board to move upward. The servo motor drives the lead screw 202 to rotate. The lead screw 202 drives the sliding block 203 to move to the right through the threaded engagement with the sliding block 203. When the solenoid valve controls the suction cup 208 to not connect with the negative pressure pump, outside air enters the suction cup 208 through the solenoid valve to break the vacuum in the suction cup 208. The FPC board falls onto the worktable 101. After the calibration component 3 calibrates the FPC board, another set of transfer components 2 picks up the FPC board and sends it to the printing machine.

[0036] like Figure 1 , Figure 2 and Figure 6 As shown, in a preferred embodiment of the present invention, the calibration component 3 includes a mounting frame 301, a rotating disk 302, and a motor 303. The mounting frame 301 is fixed on the workbench 101, the rotating disk 302 is rotatably connected to the mounting frame 301, the motor 303 is fixed on the mounting frame 301, and the rotating end of the motor 303 is connected to the rotating disk 302. The workbench 101 is provided with four sets of first guide grooves 305 in a ring, and a sliding block 304 is slidably connected in the first guide groove 305. The rotating disk 302 is provided with four sets of inclined second guide grooves 306 in a ring, and the sliding block 304 is also slidably connected in the second guide groove 306.

[0037] In this embodiment of the invention, the transfer assembly 2 places the FPC board between four sliding blocks 304. The motor 303 drives the rotating disk 302 to rotate. The rotating disk 302 pushes the sliding blocks 304 to move in the first guide groove 305 through the second guide groove 306, thereby causing the four sliding blocks 304 to move synchronously towards each other and push the FPC board, thereby correcting the FPC board and improving the loading accuracy.

[0038] like Figures 1-3 As shown, in a preferred embodiment of the present invention, the limiting descent assembly 4 includes a ratchet plate 402, a first guide slider 404, and a first compression spring 406. A first mounting groove 401 is provided on the guide post 106, and the ratchet plate 402 is fixed in the first mounting groove 401. A first guide slide groove 403 is provided on the lifting support plate 107. The first guide slider 404 is slidably connected in the first guide slide groove 403. A pull rod and a first meshing tooth 405 are respectively fixed at both ends of the first guide slider 404, and the first meshing tooth 405 meshes with the ratchet plate 402. The first compression spring 406 is provided in the first guide slide groove 403 and is sleeved on the pull rod.

[0039] In this embodiment of the invention, the first compression spring 406 pushes the first guide slider 404 to move, and the first guide slider 404 drives the first meshing tooth 405 to mesh with the ratchet plate 402, thereby restricting the downward movement of the lifting support plate 107.

[0040] like Figures 1-3As shown, in a preferred embodiment of the present invention, the climbing mechanism 5 includes a connecting plate 501, a guide rod 502, a second compression spring 503, a first rack 505, a first rotating shaft 507, a rotating sleeve 508, a first gear 509, a second gear 510, a second rack 512, and a transmission assembly 6. The connecting plate 501 is fixed on the bearing plate 108, and the bearing plate 108 is slidably connected to the lifting support plate 107. The guide rod 502 is fixed on the lifting support plate 107. The second compression spring 503 is sleeved on the guide rod 502, and both ends of the second compression spring 503 are respectively connected to the connecting plate 501 and the guide rod 502. A second mounting groove 504 is provided on the bearing plate 108, and the first rack 505 is fixed to the first rotating shaft 507, a rotating sleeve 508, a first gear 509, a second gear 510, a second rack 512, and a transmission assembly 6. Within the second mounting slot 504, the lifting support plate 107 is provided with a third mounting slot 506. The first rotating shaft 507, the rotating sleeve 508, and the second gear 510 are all rotatably connected within the third mounting slot 506. The first rotating shaft 507 is located within the rotating sleeve 508. The first gear 509 is fixed on the rotating sleeve 508 and meshes with the first rack 505. The guide post 106 is provided with a fourth mounting slot 511. The second rack 512 is fixed within the fourth mounting slot 511, and the second gear 510 meshes with the second rack 512. The transmission assembly 6 is located within the third mounting slot 506 and is used to drive the first gear 509 and the second gear 510 in a transmission engagement.

[0041] In this embodiment of the invention, when the suction cup 208 moves downward and picks up the FPC board, it exerts a downward thrust on the support plate 108 and pushes the support plate 108 downward. The support plate 108 drives the first rack 505 to move downward, the first rack 505 drives the first gear 509 to rotate counterclockwise, and the first gear 509 drives the rotating sleeve 508 to rotate counterclockwise. When the rotating sleeve 508 rotates counterclockwise, the transmission component 6 is not in operation. When the suction cup 208 picks up the FPC board and moves upward, the second compression spring 503 pushes the support plate 108 through the connecting plate 501. 08 moves upward, the bearing plate 108 drives the first rack 505 to move upward, the first rack 505 drives the first gear 509 to rotate clockwise, the first gear 509 drives the rotating sleeve 508 to rotate clockwise, the rotating sleeve 508 drives the first rotating shaft 507 to rotate through the transmission assembly 6, the transmission assembly 6 then drives the second gear 510 to rotate, the second gear 510 drives the lifting support plate 107 to move upward through the second rack 512, the lifting support plate 107 drives the bearing plate 108 to move upward and realizes the upward feeding of the FPC board.

[0042] like Figure 5As shown, in a preferred embodiment of the present invention, the transmission assembly 6 includes a first pulley 601, a belt 602, a second pulley 603, a ratchet 604, a second guide slider 606, a second meshing tooth 607, and a transmission compression spring 608. The first pulley 601 and the second pulley 603 are respectively fixed on the second gear 510 and the first rotating shaft 507. The first pulley 601 and the second pulley 603 are connected by the belt 602. The ratchet 604 is fixed on the first rotating shaft 507. The rotating sleeve 508 is provided with a second guide groove 605. The second guide slider 606 is slidably connected in the second guide groove 605. The second meshing tooth 607 and the transmission compression spring 608 are respectively fixed at both ends of the second guide slider 606, and the second meshing tooth 607 meshes with the ratchet 604.

[0043] In this embodiment of the invention, when the rotating sleeve 508 rotates counterclockwise, the second meshing tooth 607 does not mesh with the ratchet 604. When the first gear 509 drives the rotating sleeve 508 to rotate clockwise, the rotating sleeve 508 drives the first rotating shaft 507 to rotate by meshing the second meshing tooth 607 with the ratchet 604. The first rotating shaft 507 drives the second gear 510 through the first pulley 601, the belt 602 and the second pulley 603. The second gear 510 drives the lifting support plate 107 to move upward through the second rack 512.

[0044] like Figure 1 and Figure 4 As shown in the preferred embodiment of the present invention, a warning light 701 is fixed on the workbench 101, and a first sliding rod 703 and a second sliding rod 705 are fixed on the other side of the workbench 101. A first conductive block 704 and a second conductive block 706 are slidably connected to the first sliding rod 703 and the second sliding rod 705, respectively. A push spring 706 is sleeved on both the first sliding rod 703 and the second sliding rod 705. One end of the push spring 706 is connected to the workbench 101 and the first conductive block 704, respectively, and the other end of the push spring 706 is connected to the workbench 101 and the second conductive block 706, respectively. A live wire 702 is connected to the warning light 701, and the live wire 702 is closed through the first conductive block 704 and the second conductive block 706.

[0045] In this embodiment of the invention, the live wire 702 and the neutral wire of the warning light 701 are both connected to the air switch in the distribution cabinet. The live wire 702 is disconnected in the middle and connected to the first conductive block 704 and the second conductive block 706. The live wire 702 is closed by the contact between the first conductive block 704 and the second conductive block 706. When there are few FPC boards on the lifting support plate 107, the lifting support plate 107 moves upward to a higher position. The lifting support plate 107 will push the first conductive block 704 to move upward. When the first conductive block 704 moves upward, it contacts the second conductive block 706. At this time, the live wire 702 is closed, the warning light 701 is energized and lights up, reminding the worker that there are few FPC boards on the lifting support plate 107 and to pay attention to adding FPC boards.

[0046] The above embodiments of the present invention provide a feeding mechanism for automatic printing and processing of FPC boards. In use, the worker places the FPC board on the support plate 108, then closes the cabinet door 105. The cylinder 204 extends and drives the transfer plate 207 downwards. The transfer plate 207 drives the suction cup 208 to contact the FPC board, creating a moving pressing force between the suction cup 208 and the FPC board, thus ensuring sufficient contact between the suction cup 208 and the FPC board. A solenoid valve controls the connection between the suction cup 208 and the negative pressure pump, allowing the suction cup 208 to pick up the FPC board. The cylinder 204 retracts and drives the FPC board upwards. A servo motor drives the lead screw 202 to rotate. The lead screw 202, through a threaded engagement with the sliding block 203, drives the sliding block 203 to move to the right. The solenoid valve controls... When the suction cup 208 is not connected to the negative pressure pump, outside air enters the suction cup 208 through the solenoid valve, breaking the vacuum in the suction cup 208. The FPC board falls onto the worktable 101. The motor 303 drives the rotating disk 302 to rotate. The rotating disk 302 pushes the sliding block 304 to move in the first guide groove 305 through the second guide groove 306, thereby causing the four sliding blocks 304 to move synchronously towards each other and push the FPC board, thus correcting the FPC board and improving the feeding accuracy. The transfer assembly 2 on the right then sends the calibrated FPC board to the printing machine, improving the feeding accuracy. At the same time, the first compression spring 406 pushes the first guide slider 404 to move. The first guide slider 404 drives the first meshing tooth 405 to mesh with the ratchet plate 402, thereby limiting the movement of the FPC board. When the lifting support plate 107 moves downward and the suction cup 208 moves downward to pick up the FPC board, it will exert a downward thrust on the support plate 108 and push the support plate 108 downward. The support plate 108 drives the first rack 505 to move downward. The first rack 505 drives the first gear 509 to rotate counterclockwise. The first gear 509 drives the rotating sleeve 508 to rotate counterclockwise. When the rotating sleeve 508 rotates counterclockwise, the second meshing tooth 607 does not mesh with the ratchet 604. Therefore, when the rotating sleeve 508 rotates counterclockwise, the transmission assembly 6 does not drive. When the suction cup 208 picks up the FPC board and moves upward, the second compression spring 503 pushes the support plate 108 upward through the connecting plate 501. The support plate 108 drives the first rack 505 to move upward. The first rack 505 drives the first gear 505 to move downward. The first gear 509 rotates clockwise, causing the rotating sleeve 508 to rotate clockwise. The rotating sleeve 508, through the engagement of the second meshing tooth 607 with the ratchet 604, drives the first rotating shaft 507 to rotate. The first rotating shaft 507, through the first pulley 601, belt 602, and second pulley 603, drives the second gear 510. The second gear 510, through the second rack 512, drives the lifting support plate 107 to move upward. The lifting support plate 107 drives the carrying plate 108 to move upward, thus realizing the upward feeding of the FPC board. The lifting support plate 107 drives the carrying plate 108 to move upward, thereby causing the carrying plate 108 to automatically move upward each time the FPC board is grabbed, ensuring that the transfer assembly 2 grabs the FPC board at the same height each time.The transfer component 2 facilitates the grabbing of FPC boards, enabling automatic feeding of FPC boards, reducing manual operation, and improving feeding accuracy. Workers only need to add multiple FPC boards to the support plate 108 at once when there is a shortage.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
