Description

Technical Field

[0001] The utility model relates to the technical field of display devices, and particularly relates to a special-shaped FPC bending device. Background Art

[0002] In the production process of display devices, the FPC needs to be bonded to the LCD panel through a FOG (Flexible On Glass) device, and then glue is applied to the ITO position on the LCD panel.

[0003] Before applying glue, the display module of the LCD panel and the FPC needs to be transported from the FOG device to the designated position of the glue dispenser. During the transportation process, the transportation arm often uses the method of vacuum adsorption to fix the display module. In the face of special-shaped FPC projects, the vacuum suction nozzle can still adsorb the special-shaped FPC.

[0004] However, in various special-shaped FPC projects, the shapes and sizes of the FPCs are different, and there is a situation where the FPC blocks the ITO position on the LCD panel. In the steps from bonding to applying glue, the transportation arm or other mechanical components of the glue application device lack the bending treatment for special-shaped FPCs to avoid the glue application position. If the display module is additionally placed in a device dedicated to folding the FPC from the transportation path, or the worker manually operates to bend the FPC, the production efficiency will be greatly reduced, and the labor and time costs will be increased. At the same time, the risk of damaging the FPC during the operation is greatly increased. Summary of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a special-shaped FPC bending device, aiming to solve the problem that in the prior art, the special-shaped FPC blocks the glue application position and there is a lack of a safe and efficient means to bend the special-shaped FPC on the way of transporting it to the glue dispenser.

[0006] In order to achieve the above purpose, the utility model is realized through the following technical solutions:

The end that is placed on the display panel is turned to the bottom surface of the display panel, no longer blocking the dispensing.

[0031] A second support groove 201 is provided on the top surface of the second support 200. A plurality of second fixing arms 300 are slidably connected in the second support groove 201. A plurality of limiting handles 303 are provided on the second fixing arms 300. The limiting handles 303 are used to fix the positions of the second fixing arms 300. Two sliding platforms 310 are slidably connected to the second fixing arms 300. Specifically, second sliding grooves 301 are provided on the side walls of the second fixing arms 300. The sliding platforms 310 are slidably connected to the second sliding grooves 301. Second limiting members 312 are provided on the sliding platforms 310. The second limiting members 312 are used to fix the positions of the sliding platforms 310. A plurality of scale marks 302 are provided on the top surfaces of the second fixing arms 300.

The second suction members 320 include second positioning columns 321, second telescopic rods 323 and second suction nozzles 324. The side walls of the second positioning columns 321 are slidably connected to the third adjustment grooves 311. The bottom ends of the second positioning columns 321 are connected to the second telescopic rods 323. Second connecting portions 322 are provided at the ends of the second positioning columns 321 facing away from the second telescopic rods 323. The second connecting portions 322 are used to connect the vacuum tubes. The ends of the second telescopic rods 323 facing away from the second positioning columns 321 are connected to the second suction nozzles 324. Preferably, two of the second supports 200 are provided. The second fixing arms 300 are perpendicular to the second supports 200. One of the second fixing arms 300 is connected to the two second supports 200 at the same time. The second fixing arms 300 have good stability. The two sliding platforms 310 on one of the second fixing arms 300 are located on both sides of the two second supports 200. The scale marks 302 facilitate the operator to adjust the precise positions of the sliding platforms 310 when maintaining the device to adapt to display panels 400 of different sizes. The structures of the second suction members 320 and the first suction members 113 are the same. The third adjustment grooves 311 are parallel to the second supports 200. Understandably, the positions of the second suction members 320 can be adjusted by moving away from or approaching the first support 100 and the second support 200, with flexible adjustment and strong applicability.

[0032] Please refer to Figure 5, the height of the second suction nozzle 324 is equal to that of the first suction nozzle, and the height of the contact part 153 is lower than or equal to that of the first suction nozzle. Preferably, the contact part 153 is made of rubber material. After the FPC and the display panel 400 are bonded in the FOG device, the formed display module is carried. The display module is placed on the working platform. The four second suction nozzles 324 adsorb the display panel 400, and one first suction nozzle adsorbs one end of the L-shaped part 410 connecting the bent part 420. During the working process, the adsorption is completed by the overall downward movement of the handling arm, that is, the special-shaped FPC bending device moves downward as a whole, then the contact part 153 abuts against the bent part 420 and slides under the support of the working platform. The spring 154 is compressed, and the ejector rod 152 slides upward relative to the sleeve 151. At this time, the first suction nozzle, the second suction nozzle 320 and the pushed contact part 153 are on the same plane. After the adsorption is firm, the special-shaped FPC bending device is lifted with the handling arm. The pushing member 150 restores its length under the action of the spring 154, and the ejector rod 152 and the contact part 153 push downward to bend the bent part 420 downward. Due to the flexible characteristic of the FPC, when the bent part 420 is bent downward by a certain angle, one end lapping on the top surface of the display panel 400 is driven to leave the display panel and is folded to the bottom surface of the display panel, exposing the ITO position for easy dispensing. If the FPC is relatively soft and the length of the bent part 420 is long, the first suction nozzle and the second suction nozzle 324 can rise with the first telescopic rod and the second telescopic rod 323 respectively to further increase the height difference between the first suction nozzle and the contact part 153. It can be understood that the bending amplitude of the FPC can be guaranteed, and the bent part 420 can be bent to the back of the display panel 400 to facilitate exposing the dispensing position for the dispenser to perform dispensing in the subsequent process. The bending process of the special-shaped FPC is combined with the handling process, greatly improving the production efficiency, and the FPC does not need to be touched manually during the process, preventing negative impacts on the FPC caused by manual operation errors.
