Description

Technical Field

[0001] This invention relates to the field of automated equipment, and more particularly to an automatic fastening device for FPC. Background Technology

[0002] Currently, in the assembly process of electronic products such as mobile phones, FPC (Flexible Printed Circuit) cables need to be fastened to the motherboard and sub-boards inside the phone casing. Existing production lines generally use manual or semi-automatic methods: workers remove FPC cables one by one from a tray, visually align them, and then place them into the phone casing, where subsequent processes perform pressing or simple shaping. This method has the following shortcomings: 1. FPC cables are flexible components, small in size and easily deformed. Manually picking up, handling and aligning them from the pallet not only makes it difficult to improve efficiency, but also the large differences in the movement habits of different operators can easily lead to unstable assembly rhythm and limited assembly capacity, making it difficult to meet the efficiency requirements of mass production.

[0003] 2. The FPC fastening position is often in a narrow space and requires high accuracy in planar and height positioning. Manual or simple fixture positioning is difficult to ensure that both ends and the middle of the FPC cable are precisely fitted with the fastening structure on the mobile phone shell. This can easily lead to misalignment, lifting, or partial insecure fastening, resulting in poor electrical performance or reassembly repair, which affects the product yield.

[0004] 3. Although some existing automatic placement equipment is equipped with a suction mechanism, most of them operate according to a fixed program and lack the precise visual positioning and posture correction function of combining upper and lower cameras. They cannot identify and correct slightly offset or rotated FPC cables in the tray, resulting in the accumulation of placement position errors and affecting the fastening quality.

[0005] 4. In traditional production lines, the conveying structure for mobile phone casings and the FPC mounting device are often arranged separately, resulting in poor connection between various processes and low assembly efficiency.

[0006] 5. Existing FPC snap-fit ​​assembly equipment can generally only handle FPC cables with two connectors, and there is no FPC snap-fit ​​assembly equipment with multiple connectors.

[0007] In summary, existing FPC fastening assembly equipment still suffers from problems such as low automation, inaccurate positioning, low yield, and high degree of manual intervention in areas such as precise visual positioning and posture adjustment of FPC wiring, integrated connection with mobile phone casing conveyor lines, and re-inspection, waste removal, pressure holding, and shaping. Summary of the Invention

[0008] In view of the above technical problems, the present invention provides an automatic FPC fastening device to solve the problems of low automation, inaccurate positioning, low yield and high degree of manual intervention in current FPC fastening assembly equipment. It realizes an automatic FPC fastening device with reasonable structure and coordinated operation, which can realize automatic material picking, transfer positioning, fastening and mounting, and subsequent re-inspection and pressure holding shaping of FPC lines, so as to improve the overall production efficiency and assembly quality.

The main module assembly uses a conveyor line in conjunction with two lifting and positioning components and two lifting and clamping components to arrange the scanning station, re-inspection station, mounting station, and pressure-holding and shaping station in an orderly manner along the conveyor line. The lifting and positioning components are used to lift and intercept the housing after it arrives in place, and the lifting and clamping components use first and second stop baffles to clamp the phone housing, effectively preventing the housing from shifting or shaking during FPC mounting and subsequent shaping processes, thus improving assembly stability. The mounting module is equipped with two sets of opposing mounting modules. Each set of mounting modules includes a first mounting component with a spline shaft and a second mounting component that can rotate around the spline shaft. Together with the second upper camera component, it realizes the visual positioning of the two ends of the FPC cable. The two sets of mounting modules can respectively attach to the two ends of the same FPC cable and move synchronously to send the FPC cable to the lower camera module to complete the precise positioning of the fastening point before mounting it into the corresponding mobile phone shell. This not only realizes the high-precision assembly of the four-connector FPC, but also effectively improves efficiency and is suitable for mass continuous production. This disclosure integrates functions such as pallet feeding, FPC material picking and transfer, mobile phone casing scanning and conveying, FPC automatic fastening, online re-inspection, waste discharge and pressure holding shaping into a single device, forming an FPC wiring automatic fastening production device with continuous processes and unified rhythm.

The fourth slide 6224 is connected to the third slide 6222 via a slider and a slide rail. A second connecting post 6225 is inserted into the bottom of the fourth slide 6224. A second spring is sleeved on the second connecting post 6225, and the bottom of the second connecting post 6225 forms a limit on the second spring, so that the second spring is limited inside the fourth slide 6224. The two sides of the fourth slide 6224 are connected to a fifth connecting seat 6227 via sliders and slide rails. A second pressure sensor 6226 is mounted in the fifth connecting seat 6227. The second connecting post 6225 pushes against the second pressure sensor 6226. The fifth connecting seat 6227 is also connected to the second mounting head 6221.

[0035] like Figures 18 to 20 As shown, a waste removal and shaping module 7 is installed above the re-inspection station 503 and the pressure holding and shaping station 504. The waste removal and shaping module 7 includes a third execution module 71 with a Y-axis movement direction, a waste removal component 72 driven by the third execution module 71 and corresponding to the re-inspection station 503, a pressure holding and shaping component 73 located on one side of the third execution module 71 and corresponding to the pressure holding and shaping station 504, and a waste removal conveyor line 74. The waste removal component 72 includes a seventh cylinder 721 and a rotary cylinder 72 driven by the seventh cylinder 721 for lifting and lowering. 2. The second clamping cylinder 723, driven to rotate by the rotary cylinder 722, and the second clamping head 724, driven to open and close by the second clamping cylinder 723, are included in the waste removal assembly 72. The waste removal assembly 72 also includes a first rotary motor 725 and a laser height measuring device driven to rotate by the first rotary motor 725. The laser height measuring device is used to measure the height of the FPC cable 9 fastening position in the mobile phone casing 10 on the re-inspection station 503. For mobile phone casings 10 that fail the height measurement, the waste removal assembly 72 clamps and rotates the position before placing them on the waste removal conveyor line 74.

[0036] The pressure-holding and shaping assembly 73 includes an eighth cylinder 731, a second connecting seat 732 driven to rise and fall by the eighth cylinder 731, shaping blocks 733 respectively connected to both sides of the second connecting seat 732, a ninth cylinder 734 disposed in the middle of the second connecting seat 732, a heater 735 driven to rise and fall by the ninth cylinder 734, and a pressure-holding block 736 disposed at the bottom of the heater 735. When the shaping block 733 and the pressure-holding block 736 are pressed down, the two shaping blocks 733 press against the fastening positions at both ends of the FPC cable 9, and the pressure-holding block 736 presses against the middle of the FPC cable 9, so that each part of the FPC cable 9 fits against the mobile phone casing 10.

[0037] Workflow: I. Feeding and Palletized 8-Layer Supply At the start of operation, the stacked FPC cable tray 8 is sent to the loading station 101 of the loading module 1. Multiple upright plates 11 in the loading station 101 limit and position the stacked tray 8, and the top partition components 12 on both sides clamp the two sides of the tray 8 under the drive of the first cylinder 122, and laterally clamp the stacked tray 8. The second cylinder 142 of the lifting assembly 14 drives the first pallet 141 to lift the bottom pallet 8 as a whole. The top-mounting assembly 12 releases the pallet 8, and then the lifting assembly 14 descends to the same height as the conveying height of the first conveying assembly 13, so that the pallet 8 falls on the first conveying assembly 13. The first conveying assembly 13 then transports the pallet 8 to the picking station 102. Since the length of the first conveying assembly 13 is limited, it cannot completely transfer the pallet 8 to the second pallet of the lifting assembly. At this time, the transfer assembly 15 works, and the third cylinder 152 drives the follower block 151 to rise. With the cooperation of the second motor 154, the belt drives the first connecting seat 153 to move towards the picking station 102. At this time, the follower block 151 completely pushes the pallet 8 onto the second pallet, realizing the automatic separation and transfer of a single pallet 8. The FPC cable 9 on the pallet 8 is picked up by the material picking gantry module 2. After the material picking is completed, the empty pallet 8 is lowered by the lifting component, that is, the second pallet 161 is driven to fall by the third lead screw motor 162, so that the pallet 8 falls on the second conveying component 17. The second conveying component 17 transports the pallet 8 and transfers it to other production lines, realizing the automatic turnover of the pallet 8.

[0038] II. Automatic Material Handling and Transfer Positioning for FPC Cables The material handling gantry module 2 is mounted horizontally above the material loading module 1. The first execution module 21 enables the gantry to move in the XY direction, driving the first upper camera assembly 22 and the vacuum handling head 231 mounted on the first slide 234. First, the first upper camera assembly 22 takes pictures of the FPC cables 9 in the tray 8 of the material handling station 102 to obtain the specific position and posture of each FPC cable 9. Based on the visual recognition results, the control system drives the first execution module 21, the first lead screw motor 235, and the third motor 232 to move the vacuum handling head 231 above the target FPC cable 9 and rotate to adjust its posture. Then, it lowers to absorb and accurately remove the positioned FPC cable 9 from the tray 8. Subsequently, driven by the gantry, the vacuum handling head 231 moves the FPC cable 9 to the transfer positioning module 3 and releases the FPC cable 9 at the positioning seat 31. The positioning seat 31 has a positioning groove 311 that matches the shape of the FPC cable 9, and uses a vacuum hole 312 to adsorb and fix the FPC cable 9, thereby achieving precise posture adjustment and stable maintenance of the FPC cable 9 at the transfer station.

[0039] III. Mobile Phone Case Delivery and QR Code Registration The conveyor line in the main module 5 continuously transports the mobile phone housings 10 to be assembled. When the front mobile phone housing 10 reaches the barcode scanning station 501, the lifting cylinder 511 of the first lifting and positioning component 51 drives the stop block 512 to rise from below the conveyor line, intercepting and positioning the mobile phone housing 10. The barcode scanning camera set above the barcode scanning station 501 scans and registers the stopped mobile phone housing 10, binding the relevant information with subsequent assembly and inspection data for easy traceability in the production process. After scanning is completed, the first lifting and positioning component 51 descends, and the mobile phone housing 10 continues to be transported forward with the conveyor line, sequentially entering the mounting station 502 / re-inspection station 503 and the pressure holding and shaping station 504 area.

[0040] IV. Visual positioning of the fastening points and preparation before mounting On the intermediate positioning module 3, the FPC cable 9, which has been fixed by the positioning seat 31, is first positioned by the mounting module 6. The second upper camera component 623 in each mounting module 62 takes another picture of the FPC cable 9 on the positioning seat 31 to accurately obtain the positions of both ends of the FPC. Subsequently, the first mounting component 621 and the second mounting component 622 of the same group use the first mounting head 6212 and the Z-shaped second mounting head 6221, respectively, to adsorb both ends of the same FPC cable 9 through their respective vacuum channels. The other group adsorbs the other end of the cable in the same way, and moves as a whole under the drive of the second execution module 61, so that the FPC cable 9 is transferred to the work position above the lower camera module 4. The lower camera module 4 takes a picture of the area below the fastening point (connector) of the FPC to obtain the accurate coordinate information of the connector or fastening point on the mobile phone shell 10, providing accurate spatial position information for subsequent fastening actions. When the first mounting head 6212 picks up the FPC, the first clamping head 6214 simultaneously clamps the connector of the FPC. Since the back of the connector is a steel plate, clamping ensures that the position will not shift during movement. Then, the second mounting assembly 622 needs to clamp the other connector on the same end. Since the ribbon cable is relatively soft, the other connector may experience a slight positional shift. Based on the positioning information of the second upper camera assembly 623, the third rotary motor 6219 drives the transmission gear 6216 to rotate. The transmission gear 6216 drives the bearing assembly 6215, which in turn rotates the connecting plate 6217 and the second mounting assembly 622, achieving a slight tilt adjustment.

[0041] 5. The FPC cable 9 automatically snaps into the phone case 10. When the phone casing 10 reaches the mounting station 502, the corresponding lifting and clamping assembly 52, driven by the cooperation of the fourth cylinder 522, the fifth cylinder 523, and the sixth cylinder 524, lifts the phone casing 10 from below the conveyor line. The first stop baffle 521 and the second stop baffle 525 clamp the phone casing 10 from both sides, ensuring the casing's position is stable during mounting. Based on the snap-fit ​​point coordinates fed back by the lower camera, the second execution module in the mounting module 6 drives the two mounting modules 62 to move synchronously, causing the first mounting assembly 621 and the second mounting assembly 622, which hold the FPC ends, to press down onto the corresponding connector positions on the phone casing 10 along a predetermined trajectory. Through the coordinated rotation and linear motion of the positioning shaft, bearing assembly 6215, and Z-shaped mounting head, combined with the stroke and pressure control of the second lead screw motor 6213, spring, and pressure sensor, the two ends and middle of the FPC cable 9 are accurately snapped into the fastening structure of the mobile phone housing 10 under controlled pressure, completing the automatic fastening assembly of the FPC cable 9. Specifically, the second lead screw motor drives the fourth connecting seat 62112 to rise and fall. The fourth connecting seat 62112 presses against the first connecting post and the third connecting seat 62110, causing the spline shaft 6211 to descend. Then, the first mounting head 6212 presses against the connector of the FPC cable 9, which has been fixed by the first clamping head 6214. When the value of the first pressure sensor reaches the threshold, the second lead screw motor 6213 stops driving. After the position of the second mounting component 622 is rotated and adjusted, the tenth cylinder 6223 drives the fourth slide 6224, which in turn drives the fifth connector 6227, causing the second mounting head 6221 to press the FPC connector against the snap-fit ​​position of the phone housing 10. When the value of the second pressure sensor 6226 reaches the threshold, the tenth cylinder 6223 stops driving.

[0042] VI. Re-inspection of fastening and disposal of defective products After the phone casing 10 is fastened, it continues to move along the conveyor line to the re-inspection station 503. The second lifting and positioning component 51 stops the phone casing 10, and the waste removal component 72 in the waste removal and shaping module 7 moves above the re-inspection station 503 under the drive of the third execution module 71. It then drives the second clamping head 724 to properly clamp and adjust the posture of the phone casing 10 through the seventh cylinder 721, the rotary cylinder 722, and the second clamping cylinder 723. Subsequently, the laser height measuring device scans the height of the FPC cable 9 fastening area under the drive of the first rotary motor 725 to detect whether the FPC fastening is in place and whether there is any local lifting. The control system makes a judgment based on the height measurement results: when the detection is a defective product, the waste removal component 72 clamps the phone casing 10 and adjusts its posture with the cooperation of the rotary cylinder 722, and puts it into the waste removal conveyor line to be transported to the defective product collection station; when the detection is a good product, the phone casing 10 is released and returns to the main conveyor line to enter the next station.

[0043] VII. Pressure Holding and Shaping and Final Off-line The mobile phone housing 10 determined to be a good product through re-inspection continues to enter the pressure holding and shaping station 504 along the conveyor line. The corresponding lifting and clamping assembly 52 lifts and clamps the mobile phone housing 10 again to keep it stable during the shaping process. The pressure holding and shaping assembly 73 drives the second connecting seat 732 to descend as a whole under the drive of the eighth cylinder 731. The shaping blocks 733 on both sides of it press against the fastening positions at both ends of the FPC cable 9 respectively. The heater 735 in the middle drives the pressure holding block 736 to heat and hold the middle area of the FPC cable 9 under the drive of the ninth cylinder 734. The shaping blocks 733 and the pressure holding block 736 cooperate to make the interface structures at both ends and in the middle of the FPC cable 9 fully adhere to the mobile phone housing 10 and perform thermal shaping and pressure holding, improving the fastening firmness and long-term reliability. After the pressure holding and shaping is completed, the pressure holding and shaping assembly 73 and the lifting and clamping assembly 52 are reset in sequence, and the mobile phone housing 10 falls back to the conveyor line and is finally conveyed to the subsequent functional test or general assembly process, realizing the closed-loop automatic operation of the FPC cable 9 fastening and assembly process.

[0044] It can be known from the above embodiments that the present invention has the following beneficial effects: The picking gantry module 2 is configured with a first execution module 21 and a first upper camera assembly 22 having XY moving directions, which can take pictures and identify the FPC cable 9 in the tray 8 at the loading station 101 and position its posture. The vacuum picking head 231 takes accurate materials under the drive of the first screw motor 235 and the third motor 232; the transfer positioning module 3 cooperates with the lower camera module 4 to accurately position the FPC cable 9 again and identify the fastening points on the transfer positioning seat 31, so as to ensure the accuracy of the subsequent mounting position and posture and reduce the assembly defects caused by the manual picking and placing errors. The main runner module 5 arranges the code scanning station 501, the re-inspection station 503, the mounting station 502 and the pressure holding and shaping station 504 along the conveyor line in an orderly manner through the conveyor line in cooperation with two lifting and positioning assemblies 51 and two lifting and clamping assemblies 52. The lifting and positioning assembly 51 is used to lift and intercept the housing after it arrives. The lifting and clamping assembly 52 clamps the mobile phone housing 10 through the first and second stop baffles 525, effectively preventing the housing from shifting or shaking during the FPC mounting and subsequent shaping processes and improving the assembly stability. The mounting module 6 is equipped with two sets of mounting modules 62 arranged opposite to each other. Each set of mounting modules 62 includes a first mounting component 621 with a spline shaft 6211 and a second mounting component 622 that can rotate around the spline shaft 6211. Together with the second upper camera component, it realizes the visual positioning of the two ends of the FPC cable 9. The two sets of mounting modules 62 can respectively attach to the two ends of the same FPC cable 9 and move synchronously to send the FPC cable 9 to the lower camera module 4 to complete the precise positioning of the fastening point before mounting it into the corresponding mobile phone shell 10. This not only realizes the high-precision assembly of the four-connector FPC, but also effectively improves efficiency and is suitable for mass continuous production. This invention integrates functions such as pallet 8 feeding, FPC material picking and transfer, mobile phone casing 10 scanning and conveying, FPC automatic fastening, online re-inspection, waste discharge and pressure holding shaping into a set of devices, forming an FPC wiring 9 automatic fastening production device with continuous process and unified rhythm.
