[0033] The masking paper pasting device is arranged in front of the FPC folding device, and includes a masking paper feeding and cutting mechanism 51 and a masking paper pasting module 52. The masking paper feeding and cutting mechanism 51 is used to pull out a section of masking paper according to a predetermined size for cutting. The masking paper pasting module 52, driven by the robot arm 2, takes the cut masking paper from the masking paper feeding and cutting mechanism 51 and attaches it to the FPC after being bent by the FPC folding device.

[0034] The frame is also provided with an assembly line 6 and an NG belt 7. The assembly line 5 is used for conveying the carrier, and the carrier 5 is used for storing the screen after the FPC is folded and affixed with masking paper.

The lower vision 82 is used for taking photos and positioning the FPC material with masking tape after folding the FPC in half before putting it into the carrier.

[0036] Instructions for use of the device are as follows:

[0037] The empty carrier flows into the equipment along the assembly line; the robot arm 2 drives the pick-up and put-out module 21 to move to the top of the material tray positioned by the tray transfer module 31, locates and scans the code through the upper vision 81, and absorbs the screen; the robot arm 2 drives the pick-up and put-out module 21 to move to the secondary positioning platform 41, the secondary positioning platform 41 fixes the screen, and the FPC folding module 42 bends the FPC on the screen into place; the masking paper feeding and cutting mechanism 51 pulls out a section of masking paper and cuts it; the robot arm 2 drives the masking paper pasting module 52 Move to the top of the cut masking paper, absorb the masking paper and move to the top of the secondary positioning platform 41, the masking paper sticking module 52 attaches the masking paper to the FPC to fix it; after the masking paper is attached and fixed, the secondary positioning platform 41 releases the screen, and the material taking and unloading module 21 sucks the screen and moves it to the lower vision 82 for photo positioning and then puts it into the carrier; the screen on the carrier is then photographed by the upper vision 81 to confirm whether the FPC rebounds or not, if it rebounds, it is placed on the NG belt 7; if there is no rebound, it flows into the next station along the assembly line 6.

[0038] In one specific implementation, see Figure 2 The material bin 33 in the automatic transfer device is provided with a lifting motor, which is used to lift and position the pallet with the material tray in the material bin 33. The pallet transfer module 31 is provided with a support plate 311, a tray taking cylinder 312, a rodless cylinder 313, a scraper cylinder 314 and a positioning cylinder 315. The tray taking cylinder 312 is used to absorb the material tray lifted and positioned by the lifting motor and place it on the support plate 311. The scraper cylinder 314 is used to make the empty pallet fall into the empty tray bin 32. The support plate 311 can be moved and positioned above the material bin 33 and the empty tray bin 32 with the rodless cylinder 313. The positioning cylinder 315 is used to position the material tray on the support plate 311.

[0039] After the tray of the silo 33 is lifted and positioned as the lifting motor rises, the tray-taking cylinder 312 sucks the tray, the rodless cylinder 313 drives the support plate 311 to move, the scraper cylinder 314 descends to make the empty tray fall into the empty tray silo, then the scraper cylinder 314 rises, the tray-taking cylinder 312 descends to place the sucked tray on the support plate, the rodless cylinder 313 returns to its position, and the positioning cylinder 315 positions the tray.

[0040] In another specific implementation, see Figure 3 , Figure 4 The secondary positioning platform 41 of the folding FPC device includes a clamping positioning block 411, a rotating rod 412 and first, second and third cylinders 413, 414 and 415. The clamping positioning block 411 is connected with a spring 4111 and a first bearing 4112. The first bearing 4112 is connected with a wedge-shaped block push rod 4113. The wedge-shaped block push rod 4113 lifts the first bearing 4112 as the first cylinder 413 rises, thereby driving the first bearing 4112 to press against the spring 4111 so that the clamping positioning block 411 is opened. A connecting block 416 is connected between the third cylinder 415 and the rotating rod 412. The connecting block 416 is connected with a slide block 417. The connecting block 416 moves forward and backward within the range of the slide block 416 as the third cylinder 413 is extended and retracted. The second cylinder 414 is arranged below the connecting block 416. The connecting block 416 moves up and down as the second cylinder 414 is extended and retracted.

[0041] The FPC folding module 42 of the FPC folding device includes a slide plate 421, a fourth cylinder 422 and a flipping assembly, the flipping assembly includes a flipping rod 423, a driving wheel 424, a second bearing 425, and a rotating handle 426. The vertical direction of the slide plate 421 is the Z-axis direction, and a slide groove 4211 in the ZY direction is provided on the slide plate 421. The second bearing 425 is connected in the slide groove 4211, the flipping rod 423 is connected to the rotating handle 412, and the driving wheel 424 is connected to a driven block 427. The driving wheel 424 descends with the fourth cylinder 422 to push the driven block 427 to move in the Y direction, so that the second bearing 425 moves in the slide groove 4211 in the ZY direction, and the rotating handle 426 is driven to drive the flipping rod 423 to flip the FPC on the screen clamped by the bending secondary positioning platform 41.

[0042] Specifically, the bending method of the FPC device is as follows:

[0043] When the first cylinder 413 is in the lifting state at the initial position, the wedge block push rod 4113 lifts the bearing, the spring 4111 is in a compressed state, the clamping positioning block 411 is opened, the first cylinder 413 descends, and the clamping positioning block 41 clamps the screen; because the incoming FPC material is not necessarily very flat and may warp, the second cylinder 414 is in the lifting state at the initial position, so that the rotating rod 412 is higher than the FPC to prevent the FPC from being damaged when the rotating rod 412 moves toward the FPC; the third cylinder 415 is in the retracted state at the initial position, and after the screen is clamped and positioned, the second cylinder 414 descends, the third cylinder 415 extends, the rotating rod 412 reaches the specified position, and is pressed onto the FPC to complete the positioning of the screen and the FPC on the screen.

[0044] After positioning is completed, the FPC on the screen is ready to be bent. At this time, the fourth cylinder 422 of the FPC folding module 42 descends, and the driving wheel 424 pushes the driven block 426 to move in the Y direction. The second bearing 425 then moves in the ZY direction in the slide groove 4211. During the movement of the second bearing 425, the rotating handle 412 drives the flip rod 423 to complete the flipping action and flip the FPC over and bend it.

[0045] In another specific implementation, see Figure 5 , Figure 6 , Figure 7 The masking paper feeding and cutting mechanism 51 includes a feeding assembly and a cutting assembly. The feeding assembly is connected to the cutting assembly. The feeding assembly includes a pressing cylinder 511, a pressing wheel 512, an idler wheel 513, an upper and lower cylinder, a moving cylinder 515 connected to the upper and lower cylinders, and a clamping cylinder 516 installed on the upper and lower cylinders. The cutting assembly includes a cutting cylinder 517 and a cutting knife 518. The masking paper is installed on the feeding assembly and tensioned by the idler wheel 513. The upper and lower cylinders 514 drive the clamping cylinder 516 to move to the end of the masking paper. The masking paper is clamped, and after the moving cylinder 515 moves forward to pull the masking paper out to a preset length, the pressing cylinder 511 drives the pressing wheel 512 to press the pulled masking paper, and the cutting cylinder 517 extends, and the cutting shears 518 cut the masking paper; the masking paper pasting module 52 is installed on the robot arm 2, including the sixth cylinder 525, the masking paper suction head 526, and the masking paper suction nozzle 527. The sixth cylinder 525 is lifted and lowered to drive the masking paper suction head 526 and the masking paper suction nozzle 527 to take and place the masking paper and attach it to the folded FPC.

[0046] In this specific implementation, the masking tape module 52 is driven by the robot arm 2 to move above the cut masking tape. At this time, the upper and lower cylinders 514 of the masking tape feeding and cutting mechanism 51 descend, and the clamping cylinder 516 is released to help the masking tape be completely sucked and removed. The masking tape suction head 526 sucks the masking tape and moves to the top of the secondary positioning platform 41 to attach it to the FPC.

[0047] The material taking and placing module 21 of the robot arm 2 includes a fifth cylinder 522, a mounting plate, a suction nozzle 523 and an elastic pressure maintaining head 524. The suction nozzle 523 and the elastic pressure maintaining head 524 are mounted on the mounting plate. As the fifth cylinder 522 descends, the mounting plate drives the suction nozzle 523 to suck the screen. At the same time, the elastic pressure maintaining head 524 is pressed at the bending part of the FPC to maintain pressure, but the FPC will not be crushed to prevent damage to the FPC, thereby improving the bending reliability and further ensuring the effect of subsequent masking tape.

[0048] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
