[0002] The backlight source is located behind the LCD and can control the visual effect of the LCD module. Most backlight sources use flexible light strips as the light source structure, namely FPC light strips. In LCD manufacturers, the production of backlight sources has mostly been automated.

[0003] Authorization announcement number CN220905596U discloses an FPC light strip feeding machine, which can automatically tear off the release film and realize automatic feeding, improve the automation level of the equipment, and reduce labor costs. However, the above solution still has the following problems:

[0004] 1. FPC light strips are prone to deformation after film tearing, and the existing FPC light strip feeder directly uses a grabbing mechanism to grab and feed it to the conveyor line of the backlight automation assembly equipment. There is a lack of a calibration mechanism for the FPC light strips, which leads to a decrease in the processing yield of the backlight automation assembly equipment, which is not conducive to high-quality processing requirements.

After the FPC light strip is sent out by the output mechanism, it is directly grabbed by the grabbing mechanism and placed on the conveyor line of the backlight automation assembly equipment.

[0031] like Figure 3 , 4As shown, the grabbing mechanism 6 includes a first manipulator 61 and a second manipulator 62. The first manipulator 61 is connected to the calibration transfer mechanism 7 and the conveying mechanism 5, respectively, and is used to grab the product on the conveying mechanism 5 to the calibration transfer mechanism 7.

During operation, after the conveying mechanism 5 conveys the product with the release film removed to the grabbing position of the grabbing mechanism 6, the first manipulator 61 is controlled to grab the product from the conveying mechanism 5 and place it on the calibration component 73 connected to the first manipulator 61; the position of the product is calibrated by the calibration component 73 to make it compatible with the loading position of the backlight automation assembly equipment; the switching mechanism 72 is controlled to work so that the positions of the two calibration components 73 are interchanged, so that the calibration component 73 with the product placed is connected to the second manipulator 62; the second manipulator 62 is controlled to pick up the product on the calibration component 73 and convey it to the backlight automation assembly equipment, completing the loading process of the backlight automation assembly equipment.

[0032] In actual work, the first manipulator 61 and the second manipulator 62 can work at the same time, that is, while the first manipulator 61 places the product on the calibration component 73 connected to it, the second manipulator 62 grabs the product from another calibration component 73, without waiting, thereby improving processing efficiency. The backlight FPC light bar loader can calibrate the loading position of the product by setting the calibration component 73, so that it can adapt to the loading position of the backlight automatic assembly equipment, ensure the processing yield of the backlight automatic assembly equipment, and meet the high-quality processing requirements; on the other hand, the use of two manipulators and the transposition mechanism 72 shortens the grabbing stroke of the manipulator, which can greatly improve processing efficiency and reduce costs.

[0033] In this embodiment, the gripping mechanism 6 also includes a gripping transverse shifting module 63, which is fixedly mounted on the machine base 1. The first manipulator 61 and the second manipulator 62 are respectively connected to the output ends of the gripping transverse shifting module 63, and the gripping transverse shifting module 63 can drive the first manipulator 61 and the second manipulator 62 to move laterally. In this embodiment, the first manipulator 61 and the second manipulator 62 are configured to share a transverse shifting module, which can simplify the mechanical structure and thus reduce the overall manufacturing cost of the equipment; make the equipment structure more compact, can effectively reduce the overall volume of the equipment, facilitate assembly and handling, and improve practicality. In other embodiments, the first manipulator 61 and the second manipulator 62 can also respectively adopt independent transverse shifting modules; the present invention is not limited to this.

[0034] Specifically, the grabbing and transverse movement module 63 includes a grabbing and fixing frame 631, which is connected to the machine base 1, and a linear motor 632 is provided on the grabbing and fixing frame 631. The output end of the linear motor 632 is provided with a first transverse movement slider 633 and a second transverse movement slider 634. The first manipulator 61 is connected to the first transverse movement slider 633, and the second manipulator 62 is connected to the second transverse movement slider 634. The structure of the linear motor 632 can adopt the existing structure, which will not be described in detail herein; the linear motor 632 is provided with two movers, one of which is fixedly connected to the first transverse movement slider 633, and the other mover is fixedly connected to the second transverse movement slider 634; when working, the linear motor 632 can drive the first transverse movement slider 633 and the second transverse movement slider 634 to slide transversely respectively, thereby driving the first manipulator 61 and the second manipulator 62 to move transversely respectively.

[0035] In other embodiments, the linear motor 632 can also be replaced by a motor lead screw structure, a motor pulley structure, a cylinder structure, an electric cylinder structure, or a structure in which the motor drives a bidirectional lead screw to rotate, etc.; in short, any structure that can drive the first manipulator 61 and the second manipulator 62 to move horizontally is suitable for the present invention.

[0036] The first manipulator 61 includes a manipulator front and rear modules 611, which are fixedly connected to the first transverse slider 633. A manipulator lifting module 612 is provided on the output end of the manipulator front and rear modules 611, a manipulator rotating module 613 is provided on the output end of the manipulator lifting module 612, a negative pressure suction plate 614 is provided on the output end of the manipulator rotating module 613, and a negative pressure device is externally connected to the negative pressure suction plate 614, so that the negative pressure suction plate 614 can generate negative pressure suction force to grasp and release the FPC light strip. During operation, the linear motor 632 can drive the manipulator front and rear modules 611, the manipulator lifting module 612, the manipulator rotating module 613 and the negative pressure suction plate 614 to move laterally, so that the negative pressure suction plate 614 can move back and forth between the conveying mechanism 5 and the calibration component 73; the manipulator front and rear modules 611 can drive the manipulator lifting module 612, the manipulator rotating module 613 and the negative pressure suction plate 614 to move forward and backward, so as to drive the negative pressure suction plate 614 to move to different positions of the conveying mechanism 5, so as to facilitate grabbing from different positions on the conveying mechanism 5. product; the manipulator lifting module 612 can drive the manipulator rotating module 613 and the negative pressure suction plate 614 to rise and fall, thereby driving the negative pressure suction plate 614 to connect with the conveying mechanism 5 and the calibration component 73 respectively, so as to grab the product from the conveying mechanism 5 and place it on the calibration component 73; the manipulator rotating module 613 can drive the negative pressure suction plate 614 to rotate, so that the negative pressure suction plate 614 can adjust its direction angle in time to align it with the direction of the product on the conveying mechanism 5 or the direction of the product placed on the calibration component 73, so as to ensure the stability of the processing.

[0037] In this embodiment, the front and rear modules 611 of the manipulator adopt a motor screw structure; in other embodiments, the front and rear modules 611 of the manipulator may also adopt a device or structure capable of driving linear motion, such as a cylinder, an electric cylinder, or a motor pulley. The manipulator lifting module 612 adopts a motor pulley structure; in other embodiments, the manipulator lifting module 612 may also adopt a device or structure capable of driving linear motion, such as a cylinder, an electric cylinder, or a motor screw. The manipulator rotation module 613 adopts a motor structure; in other embodiments, the manipulator rotation module 613 may also adopt other devices or structures capable of driving rotational motion.

[0038] The second manipulator 62 has the same structure as the first manipulator 61, and its structure will not be described in detail in this article; the difference is that the second manipulator 62 drives the corresponding negative pressure suction plate 614 to move back and forth between the calibration component 73 and the backlight automation assembly equipment, thereby loading the products on the calibration component 73 onto the backlight automation assembly equipment.

[0039] like Figure 5As shown, the transposition mechanism 72 includes a transposition drive 721, which is fixedly mounted on the calibration fixing seat 71. A calibration mounting block 722 is provided on the output end of the transposition drive 721. Two calibration components 73 are respectively connected to the calibration mounting blocks 722. The transposition drive 721 can drive the calibration mounting blocks 722 to rotate. When working, the calibration mounting blocks 722 are driven to rotate by the transposition drive 721, which drives the two calibration components 73 to move synchronously, thereby exchanging the positions of the two calibration components 73 to achieve the purpose of transposition. In the initial state, one of the calibration components 73 is connected to the first manipulator 61, and the other calibration component 73 is connected to the second manipulator 62; when the first manipulator 61 places the FPC light bar on the corresponding calibration component 73, the transposition drive 721 is controlled to work, driving the calibration mounting block 722 to rotate, thereby driving the two calibration components 73 to move synchronously, so that the positions of the two calibration components 73 are interchanged, thereby aligning the calibration component 73 with the FPC light bar and the second manipulator 62, so that the second manipulator 62 can grab and load the FPC light bar on the calibration component 73.

[0040] In this embodiment, the transposition drive member 721 is a transposition drive motor, which is fixedly mounted on the calibration fixing seat 71, and the calibration mounting block 722 is fixedly connected to the output shaft of the transposition drive motor. In other embodiments, the transposition drive member 721 can also be other devices or structures capable of driving rotational motion, such as a motor gear structure, a motor pulley structure, etc.

[0041] The calibration assembly 73 includes a product placement block 731, a horizontal clamping cylinder 732, and a vertical clamping cylinder 733. The product placement block 731, the horizontal clamping cylinder 732, and the vertical clamping cylinder 733 are respectively fixedly connected to the calibration mounting block 722. The product placement block 731 is used to place the FPC light bar. The product placement block 731 is externally connected to a negative pressure device, so that the product placement block 731 can be negatively pressured to suck the product, so as to avoid the FPC light bar from shifting on the product placement block 731 when the transposition drive 721 is working, thereby improving the stability of the processing. The horizontal clamping cylinder 732 is used to calibrate the horizontal position of the product on the product placement block 731, and the vertical clamping cylinder 733 is used to calibrate the vertical position of the product on the product placement block 731. Specifically, a transverse push rod 734 is provided on the output end of the transverse clamp cylinder 732, and the transverse clamp cylinder 732 can drive the transverse push rod 734 to move towards or away from the product placement block 731. A longitudinal push rod 735 is provided on the output end of the longitudinal clamp cylinder 733, and the longitudinal clamp cylinder 733 can drive the longitudinal push rod 735 to move towards or away from the product placement block 731. During operation, after the first manipulator 61 places the FPC light bar on the product placement block 731, it controls the transverse clamp cylinder 732 and the longitudinal clamp cylinder 733 to work; the transverse clamp cylinder 732 will drive the transverse push rod 734 to move in the direction close to the product placement block 731, and the transverse push rod 734 will connect with the FPC light bar on the product placement block 731, and push the FPC light bar to move horizontally on the product placement block 731 until the transverse position of the FPC light bar is calibrated to the appropriate position; the longitudinal clamp cylinder 733 will drive the longitudinal push rod 735 to move in the direction close to the product placement block 731, and the longitudinal push rod 735 will connect with the FPC light bar on the product placement block 731, and push the FPC light bar to move longitudinally until the longitudinal position of the FPC light bar is calibrated to the appropriate position. When the FPC light bar is calibrated on the product placement block 731, the product placement block 731 generates negative pressure suction through the external negative pressure device, and the FPC light bar is firmly fixed on the product placement block 731. Then the transposition drive 721 is controlled to work, driving the calibration installation block 722 to rotate, thereby driving the two calibration components 73 to rotate synchronously, so that the positions of the two calibration components 73 are interchanged, and the product placement block 731 moves the FPC light bar to the grabbing position of the second manipulator 62, and then the horizontal clamping claw cylinder 732 and the longitudinal clamping claw cylinder 733 are controlled to reset; the horizontal clamping claw cylinder 732 will drive the horizontal push rod 734 to move away from the product placement block 731, so that the horizontal push rod 734 is separated from the FPC light bar; the longitudinal clamping claw cylinder 733 will drive the longitudinal push rod 735 to move away from the product placement block 731, so that the longitudinal push rod 735 is separated from the FPC light. Afterwards, the second robot 62 grabs the FPC light strip from the product placement block 731 and places it on the backlight panel automated assembly equipment, completing the loading process.

[0042] Through the cooperation of the transverse clamping cylinder 732 and the longitudinal clamping cylinder 733, the transverse and longitudinal positions of the FPC light bar on the product placement block 731 can be calibrated respectively, ensuring the accurate loading position of the FPC light bar, avoiding the deformation of the FPC light bar affecting the loading accuracy, improving the processing yield rate, and meeting the high-quality processing requirements. In this embodiment, two transverse push rods 734 are symmetrically arranged on the output end of the transverse clamping cylinder 732, and two longitudinal push rods 735 are symmetrically arranged on the output end of the longitudinal clamping cylinder 733; when working, the transverse clamping cylinder 732 drives the two transverse push rods 734 to move closer to or away from each other, and the longitudinal clamping cylinder 733 drives the two longitudinal push rods 735 to move closer to or away from each other, thereby improving the efficiency of the FPC light bar calibration and improving the processing efficiency.

[0043] In order to improve the accuracy of calibration, a plurality of guide slots 736 are provided on the product placement block 731, and a push block 737 adapted to the guide slots 736 is provided on the transverse push rod 734. The push block 737 is arranged one-to-one with the guide slots 736, and the transverse clamping claw cylinder 732 can drive the push block 737 to slide in the guide slots 736; when the transverse clamping claw cylinder 732 is working, it drives the transverse push rod 734 to move, thereby driving the push block 737 to slide in the guide slots 736, and the movement direction of the push block 737 is limited and guided by the guide slots 736, so as to ensure that the push block 737 can push the FPC light bar on the product placement block 731 to slide horizontally. In this embodiment, the transverse direction calibrated by the transverse clamping claw cylinder 732 is the length direction of the FPC light bar. By setting a plurality of guide slots 736 and the push block 737, it can ensure that the length direction is accurately calibrated, thereby improving the processing accuracy.

[0044] In other embodiments, a longitudinal slot may also be provided on the product placement block 731 , so that the longitudinal push rod 735 can slide in cooperation with the longitudinal slot, thereby limiting and guiding the driving direction of the longitudinal clamp cylinder 733 .

[0045] In order to limit the driving stroke of the transverse clamping cylinder 732, a transverse limit buffer 738 is installed on one of the transverse push rods 734; when the transverse clamping cylinder 732 drives the two transverse push blocks to move closer to each other, the transverse limit buffer 738 will abut against the other transverse push rod 734. At this time, the transverse push rod 734 also drives the push block 737 to calibrate the transverse position of the FPC light strip on the product placement block 731 to the preset position. The driving stroke of the transverse clamping cylinder 732 is limited by the transverse limit buffer 738 to prevent the transverse push rod 734 and the push block 737 from crushing the FPC light strip, thereby improving the stability of the work and ensuring the yield rate of processing.

[0046] In order to limit the driving stroke of the longitudinal clamp cylinder 733, a longitudinal limit buffer 739 is installed on one of the longitudinal push rods 735; when the longitudinal clamp cylinder 733 drives the two longitudinal push blocks to move closer to each other, the longitudinal limit buffer 739 will abut against the other longitudinal push rod 735. At this time, the longitudinal push rod 735 also calibrates the longitudinal position of the FPC light strip on the product placement block 731 to the preset position. The driving stroke of the longitudinal clamp cylinder 733 is limited by the longitudinal limit buffer 739 to prevent the longitudinal push rod 735 from crushing the FPC light strip, thereby improving the stability of the work and ensuring the yield rate of processing.

[0047] like Figure 1 , 2 As shown, a CCD component 8 is provided at a position on the machine base 1 corresponding to the conveying mechanism 5. The CCD component 8 is electrically connected to the controller 2. The CCD component 8 is used to capture the image of the product on the conveying mechanism 5 so as to obtain the position and orientation of the product on the conveying mechanism 5, and then control the first manipulator 61 to grab the product from the conveying mechanism 5. By setting the CCD component 8, the first manipulator 61 can accurately grab the product from the conveying mechanism 5, thereby improving the stability of processing.

[0048] Specifically, the CCD assembly 8 includes a camera mounting frame 81, which is connected to the base 1. The camera mounting frame 81 is provided with a positioning camera 82, which can capture the product image on the conveying mechanism 5. The specific operation is that the conveying mechanism 5 will convey the FPC light bar to the shooting position of the positioning camera 82, and the image of the FPC light bar will be captured by the positioning camera 82, so that the controller 2 can know the position and orientation of the FPC light bar on the current conveying mechanism 5, and then control the first manipulator 61 to work, so that the first manipulator 61 adjusts the position and grasping angle to correspond to the position angle of the FPC light bar on the conveying mechanism 5, so that the first manipulator 61 can accurately grasp the FPC light bar from the conveying mechanism 5. By setting the positioning camera 82, the accuracy of loading can be improved and the smooth processing can be guaranteed.

[0049] like Figure 2As shown, the feeding mechanism 3 includes a discharge table 31, a material picking assembly 32 and a lifting platform 33. The discharge table 31 is used to stack products. The material picking assembly 32 is connected to the discharge table 31 and the lifting platform 33 respectively. The material picking assembly 32 can grab products from the discharge table 31 to the lifting platform 33. The lifting platform 33 is connected to the film tearing mechanism 4, and the lifting platform 33 can push the products onto the film tearing mechanism 4.

[0051] Working principle:

[0052] The backlight FPC light strip loader is placed on one side of the backlight automated assembly equipment, and the second manipulator 62 can move to the feeding position of the backlight automated assembly equipment; before processing, the products to be processed are stacked and placed on the unloading table 31.

[0053] During processing, the material discharging table 31 is first controlled to work, driving the stacked FPC light strips to rise until the top FPC light strip rises to the grabbing height of the material picking component 32; then the material picking component 32 is controlled to work, and the material picking component 32 will take out the top FPC light strip from the material discharging table 31, and then place it on the lifting platform 33; then the lifting platform 33 works, driving the FPC light strip to rise to the processing height of the film tearing mechanism 4, and the film tearing mechanism 4 can take away the FPC light strip and remove the release film on the back of the FPC light strip; the FPC light strip with the release film removed will automatically fall onto the conveying mechanism 5, and then be conveyed to the grabbing position of the first manipulator 61 by the conveying mechanism 5. When the conveying mechanism 5 conveys the FPC light strip to the grabbing position of the first manipulator 61, the FPC light strip will pass through the shooting area of ​​the positioning camera 82, and the positioning camera 82 will take a photo of it, so as to obtain information such as the position and orientation of the FPC light strip on the conveying mechanism 5. Then, the grabbing and lateral movement module 63 is controlled to drive the first manipulator 61 to move to the top of the FPC light bar, and the manipulator rotation module 613 is controlled to drive the negative pressure suction plate 614 to rotate to the angle aligned with the FPC light bar on the conveying mechanism 5, and then the manipulator front and rear modules 611 and the manipulator lifting module 612 are controlled to work respectively, driving the negative pressure suction plate 614 to grab the FPC light bar from the conveying mechanism 5. Then, through the cooperation of the grabbing and lateral movement module 63, the manipulator front and rear modules 611, the manipulator lifting module 612 and the grabbing and rotating module, the FPC light bar is placed on the calibration component 73 connected to the first manipulator 61.

[0054] Then the transverse clamp cylinder 732 and the longitudinal clamp cylinder 733 are controlled to work; the transverse clamp cylinder 732 will drive the two transverse push rods 734 to move in the direction close to the product placement block 731, and the transverse push rod 734 will drive the push block 737 to move, and the push block 737 will connect with the FPC light bar on the product placement block 731, and push the FPC light bar to move horizontally on the product placement block 731 until the transverse position of the FPC light bar is calibrated to the appropriate position; the longitudinal clamp cylinder 733 will drive the two longitudinal push rods 735 to move in the direction close to the product placement block 731, and the longitudinal push rod 735 will connect with the FPC light bar on the product placement block 731, and push the FPC light bar to move longitudinally until the longitudinal position of the FPC light bar is calibrated to the appropriate position. When the FPC light bar is calibrated on the product placement block 731, the product placement block 731 generates negative pressure suction through the external negative pressure device, and the FPC light bar is firmly fixed on the product placement block 731. Then the transposition drive 721 is controlled to work, driving the calibration installation block 722 to rotate, thereby driving the two calibration components 73 to rotate synchronously, so that the positions of the two calibration components 73 are interchanged, and the product placement block 731 moves the FPC light bar to the grabbing position of the second manipulator 62, and then the horizontal clamping claw cylinder 732 and the longitudinal clamping claw cylinder 733 are controlled to reset; the horizontal clamping claw cylinder 732 will drive the horizontal push rod 734 to move away from the product placement block 731, so that the horizontal push rod 734 is separated from the FPC light bar; the longitudinal clamping claw cylinder 733 will drive the longitudinal push rod 735 to move away from the product placement block 731, so that the longitudinal push rod 735 is separated from the FPC light.

[0055] Then, the grabbing and lateral movement module 63 is controlled to drive the second manipulator 62 to move to the top of the FPC light bar on the calibration component 73; then, the manipulator front and rear modules 611, the manipulator lifting module 612 and the manipulator rotating module 613 are controlled to work respectively, and the negative pressure suction plate 614 is driven to grab the FPC light bar from the calibration component 73. Then, through the cooperation of the grabbing and lateral movement module 63, the manipulator front and rear modules 611, the manipulator lifting module 612 and the grabbing and rotating module, the FPC light bar is placed on the feeding position of the backlight automatic assembly equipment, completing the automatic feeding process of the FPC light bar.
