[0023] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] See also Figure 1The present invention provides a keyboard backlight module FPC attachment device, comprising: a machine platform 1, a feeding mechanism 2 arranged at one side of the machine platform 1, a pick-up and discharge robot 3 arranged beside the feeding mechanism 2, a turntable mechanism 4 arranged beside the pick-up and discharge robot 3, an FPC discharge mechanism 5 arranged beside the turntable mechanism 4, and a roller pressing mechanism 6 arranged beside the turntable mechanism 4. A plurality of backlight module fixtures 41 are arranged on the turntable mechanism 4. The turntable mechanism 4 drives the backlight module fixture 41 to move to the side of the pick-up and discharge robot 3, the FPC discharge mechanism 5 or the roller pressing mechanism 6. During operation, the feeding mechanism 2 transports the backlight module to be processed. At the same time, the film on the FPC to be pasted is torn off manually, and the FPC is placed on the FPC discharge mechanism 5 with the adhesive facing upward. The FPC is transferred to the backlight module fixture 41 on the turntable mechanism 4 close to the FPC discharge mechanism 5. The turntable mechanism 4 is started to move the backlight module fixture 41 carrying the FPC to a position close to the pick-up and discharge robot 3. The pick-up and discharge robot 3 is started to pick up the backlight module from the feeding mechanism 2 and place the backlight module on the backlight module fixture 41. Then the rolling mechanism 6 is started to roll the backlight module so that the backlight module and the FPC are tightly fitted. After the fitting is completed, the backlight module is moved to the side of the rear-end material taking device by the turntable mechanism 4 and taken by the rear-end material taking device.

[0025] The FPC unloading mechanism 5 comprises: a staggered feeding mechanism 51 disposed beside the turntable mechanism 4 and a transplanting mechanism 52 disposed beside the staggered feeding mechanism 51. The transplanting mechanism 52 is suspended above the staggered feeding mechanism 51 and the turntable mechanism 4.

[0026] See also Figure 1 , Figure 2 The staggered feeding mechanism 51 includes: a plurality of staggered moving modules 511 arranged on the machine 1, a moving table 512 arranged on the moving end of the staggered moving modules 511, and an FPC fixture 513 arranged on the moving table 512. A placement groove 514 is arranged on the FPC fixture 513. Different groups of the staggered moving modules 511 are arranged in parallel. A first detection mechanism 515 is arranged beside the staggered moving modules 511. A second detection mechanism 516 is arranged on the turntable mechanism 4. The second detection mechanism 516 is suspended above the backlight module fixture 41 close to the staggered feeding mechanism 511.

[0027] See also Figure 3The transplanting mechanism 52 includes: a transplanting gantry 521 disposed on the machine 1, a transplanting motion module 522 disposed on the transplanting gantry 521, a transplanting bracket 523 disposed on the motion end of the transplanting motion module 522, a transplanting lifting mechanism 524 disposed on the transplanting bracket 523, a rotating mechanism 525 disposed on the output end of the transplanting lifting mechanism 524, a rotating plate 526 connected to the output end of the rotating mechanism 525, and a plurality of transplanting suction cups 527 disposed on the rotating plate 526. The transplanting motion module 522 drives the transplanting bracket 523 to perform linear reciprocating movement. The transplanting lifting mechanism 524 drives the rotating mechanism 525 to perform up and down reciprocating movement. The rotating mechanism 525 drives the rotating plate 526 to rotate.

[0028] By manually tearing off the film on the FPC and placing the FPC in the placement slot 514 on the FPC fixture 513, when the first detection mechanism 515 detects that the FPC is loaded on the FPC fixture 513, the corresponding staggered moving module 511 is activated, so that the FPC fixture 513 loaded with the FPC is moved to the bottom of the transplanting mechanism 52, and at the same time, the unloaded FPC fixture 513 is moved to the placement position by another set of staggered moving modules 511, so that the operator can place the next FPC. When the FPC fixture 513 loaded with the FPC moves to the bottom of the transplanting mechanism 52, the transplanting movement module 522 and the transplanting lifting module 524 are successively started, and the transplanting suction cup 527 is close to the FPC and the FPC is sucked and taken. Then the transplanting movement module 522 moves the FPC to the top of the backlight module fixture 41, and places the FPC on the backlight module fixture 41, completing the transplanting of the FPC. The second detection mechanism 516 detects that an FPC is placed on the backlight module fixture 41, and drives the turntable mechanism 4 to rotate, thereby moving the backlight module fixture 41 loaded with the FPC to the side of the material picking and discharging manipulator 3, so as to facilitate the bonding of the backlight module and the FPC. At the same time, the unloaded backlight module fixture 41 is moved to the side of the FPC discharging mechanism 5, waiting for the transfer mechanism 52 to place the FPC on the backlight module fixture 41, so as to realize automatic material picking. In this way, the efficiency and quality of FPC bonding can be improved. By placing the FPC in the placement slot 514, the relative position of the FPC picked up by the transfer mechanism 52 each time remains unchanged, so as to ensure that the placement position of the FPC is the same each time the FPC is placed on the backlight module fixture 41, and the bonding effect and the quality of the electrical connection between the FPC and the backlight module are ensured. When the specifications of the FPC are different, only the corresponding FPC fixture 513 needs to be replaced, which has wide adaptability and effectively reduces the processing cost of the auxiliary fixtures required for products of different specifications.

[0029] In some embodiments, a safety grating 517 is provided beside the staggered feeding mechanism 51. When the operator places the FPC on the FPC fixture 513, the arm passes through the safety grating 517, and the safety grating 517 detects the obstacle and sends a corresponding detection signal to the system, thereby avoiding injury to the operator due to the operation of the mechanism when the operator is placing the material, thereby improving safety.

[0030] See also Figure 4 The rolling mechanism 6 includes: a rolling gantry 61 disposed on the machine 1, a first rolling motion module 62 disposed on the rolling gantry 61, a second rolling motion module 63 disposed on the motion end of the first rolling motion module 62, a rolling lifting mechanism 64 disposed on the motion end of the second rolling motion module 63, and a plurality of soft wheels 65 disposed on the output end of the rolling lifting mechanism 64. The first rolling motion module 62 and the second rolling motion module 63 are perpendicular to each other. After the backlight module and the FPC are bonded, the soft wheels 65 are used to reciprocate and roll on the backlight module, so that the FPC and the backlight module are closely bonded.

[0031] A lower visual positioning mechanism 71 is provided beside the pick-up and place robot 3. After the pick-up and place robot 3 picks up the backlight module from the loading mechanism 2, the lower visual positioning mechanism 71 performs image recognition to detect whether the surface of the backlight module to be attached with the FPC faces downward, so as to ensure the connection effect between the FPC and the backlight module.

[0032] An upper visual positioning mechanism 72 is provided beside the pick-up and place robot 3. The upper visual positioning mechanism 72 includes: a camera moving module provided on the machine platform 1, and a plurality of visual cameras provided on the moving end of the camera moving module. The camera moving module is suspended above the turntable mechanism 4. When the turntable mechanism 4 moves the backlight module fixture 41 loaded with FPC to the side of the pick-up and place robot, the upper visual positioning mechanism 72 performs image recognition detection on the FPC in the backlight module fixture 41 to confirm the arrival of the FPC and whether the placement position of the FPC meets the requirements, so as to ensure the bonding quality of the backlight module.

[0033] See also Figure 5 , Figure 6, the feeding mechanism 2 includes: a conveyor belt 21 arranged on the machine 1, and a flip mechanism 22 arranged beside the conveyor belt 21. The flip mechanism 22 includes: a flip bracket 221 arranged beside the conveyor belt 21, a flip drive unit 222 arranged on the flip bracket 221, a flip plate 223 connected to the output end of the flip drive unit 222, and a vacuum suction plate 224 arranged on the flip plate 223. The flip bracket 221 is provided with a buffer pad 225 and a third detection mechanism 226 on both sides of the flip plate 223 corresponding to the flip plate 223. After the front-end device realizes the hot pressing and labeling of the backlight module, the upward side of the backlight module is opposite to the upward side required when the FPC is attached. Therefore, when the conveyor belt 21 transports the backlight module to the right place, the flip drive unit 222 is started to drive the flip plate 223 to rotate, so that the vacuum suction plate 224 contacts the backlight module and adsorbs the backlight module. Then the flip driving unit 222 performs reverse operation to reset the flip plate 223, thereby realizing the flipping of the backlight module and facilitating the picking up by the material taking and placing robot 3.

[0034] In some embodiments, the feeding mechanism 2 further includes: a silo 23 disposed beside the flipping mechanism 22, and a material taking mechanism 24 disposed beside the silo 23. The material taking mechanism 24 is mounted above the silo 23 and the flipping mechanism 22. By setting the silo 23, when the front-end equipment fails and cannot feed materials normally, the backlight module to be pasted with the FPC is stacked in the silo 23, and the backlight module in the silo 23 is taken out in turn by the material taking mechanism 24 and placed on the vacuum suction plate 224, so that the material taking and placing robot 3 can take materials normally.

[0035] In summary, the present invention manually places the FPC on the FPC discharge mechanism, and the FPC discharge mechanism automatically sends the FPC to the turntable mechanism for transportation and bonding with the backlight module, and then the backlight module and the FPC are tightly bonded through the rolling mechanism, thereby meeting the FPC bonding requirements of the backlight module, having high processing efficiency and less manual involvement, effectively reducing the situation of defective products caused by human factors, and meeting the needs of mass production.

[0036] The above are only preferred embodiments of the present invention and are 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 in the protection scope of the present invention.
