The backlight source FPC light strip feeding machine is arranged on one side of the backlight source automated assembly equipment; when working, the product to be processed is placed on the feeding mechanism 3, and the feeding mechanism 3 is controlled to work to transport the product to the grabbing position of the first manipulator 6, and then the first manipulator 6 and the grabbing transverse shifting module 4 cooperate to grab the FPC light strip to the cache calibration mechanism 5, and then the second manipulator 7 and the grabbing transverse shifting module 4 cooperate to grab the FPC light strip from the cache calibration mechanism 5 to the feeding position of the backlight source automated assembly equipment, completing the automatic feeding process of the FPC light strip.

[0024] Specifically, the cache calibration mechanism 5 includes a cache fixing seat 51, which is fixedly connected to the machine base 1. The cache fixing seat 51 is provided with a shifting mechanism, and the shifting mechanism is provided with two calibration components 52. The shifting mechanism is used to drive the two calibration components 52 to interchange positions. The calibration components 52 are respectively connected to the first manipulator 6 and the second manipulator 7, and the calibration components 52 are used to calibrate the position of the product. During operation, after the feeding mechanism 3 conveys the FPC light strip to the grabbing position of the first manipulator 6, the first manipulator 6 is controlled to grab the product from the feeding mechanism 3, and through cooperation with the grabbing transverse shift module 4, the FPC light strip is placed on the calibration component 52 connected to the first manipulator 6; the position of the product is calibrated through the calibration component 52 to make it compatible with the loading position of the backlight automation assembly equipment; the switching mechanism is controlled to work so that the positions of the two calibration components 52 are interchanged, so that the calibration component 52 with the product placed is connected to the second manipulator 7; the second manipulator 7 is controlled to grab the product on the calibration component 52, and convey it to the backlight automation assembly equipment, completing the loading process of the backlight automation assembly equipment.

[0025] In actual operation, the first manipulator 6 and the second manipulator 7 can work simultaneously, that is, while the first manipulator 6 places the product on the calibration component 52 connected thereto, the second component grabs the product from another calibration component 52, 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 52, so that it can be adapted to the loading position of the backlight automatic assembly equipment, ensuring the processing yield of the backlight automatic assembly equipment, and meeting high-quality processing requirements; on the other hand, the use of two manipulators and the transposition mechanism shortens the grabbing stroke of the manipulator, which can greatly improve processing efficiency and reduce costs.

[0026] In this embodiment, the first manipulator 6 and the second manipulator 7 are configured to share a transverse movement module, which can simplify the mechanical structure, thereby reducing the overall manufacturing cost of the device; making the device structure more compact, which can effectively reduce the overall volume of the device, facilitate assembly and transportation, and improve practicality. In other embodiments, the first manipulator 6 and the second manipulator 7 can also use independent transverse movement modules respectively; the present invention does not limit this.

[0027] Specifically, the grabbing and transverse moving module 4 includes a grabbing and fixing frame 41, which is connected to the machine base 1, and a linear motor 42 is provided on the grabbing and fixing frame 41. A first transverse moving slider 43 and a second transverse moving slider 44 are provided on the output end of the linear motor 42. The first manipulator 6 is connected to the first transverse moving slider 43, and the second manipulator 7 is connected to the second transverse moving slider 44. The structure of the linear motor 42 can adopt the existing structure, which will not be described in detail herein; the linear motor 42 is provided with two movers, one of which is fixedly connected to the first transverse moving slider 43, and the other mover is fixedly connected to the second transverse moving slider 44; when working, the linear motor 42 can drive the first transverse moving slider 43 and the second transverse moving slider 44 to slide transversely respectively, thereby driving the first manipulator 6 and the second manipulator 7 to move transversely respectively.

[0028] In other embodiments, the linear motor 42 can also be replaced by a motor screw structure, a motor pulley structure, a cylinder structure, an electric cylinder structure, or a structure in which a motor drives a bidirectional screw to rotate, etc.; in short, any structure that can drive the first manipulator 6 and the second manipulator 7 to move horizontally is suitable for the present invention.

[0029] The first manipulator 6 includes a manipulator front and rear modules 61, which are fixedly connected to the first transverse slider 43. A manipulator lifting module 62 is provided on the output end of the manipulator front and rear modules 61, a manipulator rotating module 63 is provided on the output end of the manipulator lifting module 62, a negative pressure suction plate 64 is provided on the output end of the manipulator rotating module 63, and a negative pressure device is externally connected to the negative pressure suction plate 64, so that the negative pressure suction plate 64 can generate negative pressure suction force to grab and release the FPC light strip. During operation, the linear motor 42 can drive the manipulator front and rear modules 61, the manipulator lifting module 62, the manipulator rotating module 63 and the negative pressure suction plate 64 to move laterally, so that the negative pressure suction plate 64 can move back and forth between the feeding mechanism 3 and the calibration component 52; the manipulator front and rear modules 61 can drive the manipulator lifting module 62, the manipulator rotating module 63 and the negative pressure suction plate 64 to move forward and backward, so as to drive the negative pressure suction plate 64 to move to different positions of the feeding mechanism 3, so as to facilitate grabbing products from different positions on the feeding mechanism 3. ; The manipulator lifting module 62 can drive the manipulator rotating module 63 and the negative pressure suction plate 64 to rise and fall, thereby driving the negative pressure suction plate 64 to connect with the feeding mechanism 3 and the calibration component 52 respectively, so as to grab the product from the feeding mechanism 3 and place it on the calibration component 52; the manipulator rotating module 63 can drive the negative pressure suction plate 64 to rotate, so that the negative pressure suction plate 64 can adjust its direction angle in time to align it with the direction of the product on the feeding mechanism 3 or the direction of the product placed on the calibration component 52, thereby ensuring the stability of the processing.

[0030] In this embodiment, the front and rear modules 61 of the manipulator adopt a motor screw structure; in other embodiments, the front and rear modules 61 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 62 adopts a motor pulley structure; in other embodiments, the manipulator lifting module 62 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 rotating module 63 adopts a motor structure; in other embodiments, the manipulator rotating module 63 may also adopt other devices or structures capable of driving rotational motion.

[0031] The second manipulator 7 has the same structure as the first manipulator 6, and its structure will not be described in detail in this article; the difference is that the second manipulator 7 drives the corresponding negative pressure suction plate 64 to move back and forth between the calibration component 52 and the backlight automation assembly equipment, thereby loading the products on the calibration component 52 onto the backlight automation assembly equipment.

[0032] like Figure 3 , 4 As shown, the transposition mechanism includes a transposition drive 53, which is fixedly mounted on the cache fixing seat 51, and a calibration mounting block 54 is provided on the output end of the transposition drive 53. Two calibration components 52 are respectively connected to the calibration mounting block 54, and the transposition drive 53 can drive the calibration mounting block 54 to rotate; when working, the calibration mounting block 54 is driven to rotate by the transposition drive 53, driving the two calibration components 52 to move synchronously, thereby exchanging the positions of the two calibration components 52 to achieve the purpose of transposition. In the initial state, one calibration component 52 is connected to the first manipulator 6, and the other calibration component 52 is connected to the second manipulator 7; when the first manipulator 6 places the FPC light bar on the corresponding calibration component 52, the transposition drive 53 is controlled to work, driving the calibration mounting block 54 to rotate, thereby driving the two calibration components 52 to rotate synchronously, so that the positions of the two calibration components 52 are interchanged, so that the calibration component 52 with the FPC light bar placed is aligned with the second manipulator 7, so that the second manipulator 7 can grab and load the FPC light bar on the calibration component 52.

[0033] In this embodiment, the transposition drive member 53 is a transposition drive motor, which is fixedly mounted on the buffer fixing seat 51, and the calibration mounting block 54 is fixedly connected to the output shaft of the transposition drive motor. In other embodiments, the transposition drive member 53 can also be other devices or structures capable of driving rotational motion, such as a motor gear structure, a motor pulley structure, etc.

[0034] The calibration assembly 52 includes a product placement block 521, a horizontal clamping cylinder 522, and a vertical clamping cylinder 523. The product placement block 521, the horizontal clamping cylinder 522, and the vertical clamping cylinder 523 are respectively fixedly connected to the calibration mounting block 54. The product placement block 521 is used to place the FPC light bar. The product placement block 521 is externally connected to a negative pressure device, so that the product placement block 521 can be negatively pressured to suck the product, so as to avoid the FPC light bar from shifting on the product placement block 521 when the transposition drive 53 is working, thereby improving the stability of the processing. The horizontal clamping cylinder 522 is used to calibrate the horizontal position of the product on the product placement block 521, and the vertical clamping cylinder 523 is used to calibrate the vertical position of the product on the product placement block 521. Specifically, a transverse push rod 524 is provided on the output end of the transverse clamp cylinder 522, and the transverse clamp cylinder 522 can drive the transverse push rod 524 to move towards or away from the product placement block 521. A longitudinal push rod 525 is provided on the output end of the longitudinal clamp cylinder 523, and the longitudinal clamp cylinder 523 can drive the longitudinal push rod 525 to move towards or away from the product placement block 521. During operation, after the first manipulator 6 places the FPC light bar on the product placement block 521, it controls the transverse clamping cylinder 522 and the longitudinal clamping cylinder 523 to work; the transverse clamping cylinder 522 will drive the transverse push rod 524 to move in the direction close to the product placement block 521, and the transverse push rod 524 will connect with the FPC light bar on the product placement block 521, and push the FPC light bar to move horizontally on the product placement block 521 until the transverse position of the FPC light bar is calibrated to a suitable position; the longitudinal clamping cylinder 523 will drive the longitudinal push rod 525 to move in the direction close to the product placement block 521, and the longitudinal push rod 525 will connect with the FPC light bar on the product placement block 521, and push the FPC light bar to move longitudinally until the longitudinal position of the FPC light bar is calibrated to a suitable position. When the FPC light bar is calibrated on the product placement block 521, the external negative pressure device is used to make the product placement block 521 generate negative pressure suction, and the FPC light bar is firmly fixed on the product placement block 521. Then the transposition drive 53 is controlled to work, driving the calibration installation block 54 to rotate, thereby driving the two calibration components 52 to rotate synchronously, so that the positions of the two calibration components 52 are interchanged, and the product placement block 521 moves the FPC light bar to the grabbing position of the second manipulator 7, and then the horizontal clamping claw cylinder 522 and the longitudinal clamping claw cylinder 523 are controlled to reset; the horizontal clamping claw cylinder 522 will drive the horizontal push rod 524 to move away from the product placement block 521, so that the horizontal push rod 524 is separated from the FPC light bar; the longitudinal clamping claw cylinder 523 will drive the longitudinal push rod 525 to move away from the product placement block 521, so that the longitudinal push rod 525 is separated from the FPC light. Afterwards, the second robot 7 grabs the FPC light strip from the product placement block 521 and places it on the backlight panel automated assembly equipment, completing the loading process.

[0035] Through the cooperation of the transverse clamping cylinder 522 and the longitudinal clamping cylinder 523, the transverse and longitudinal positions of the FPC light bar on the product placement block 521 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 524 are symmetrically arranged on the output end of the transverse clamping cylinder 522, and two longitudinal push rods 525 are symmetrically arranged on the output end of the longitudinal clamping cylinder 523; when working, the transverse clamping cylinder 522 drives the two transverse push rods 524 to move closer to or away from each other, and the longitudinal clamping cylinder 523 drives the two longitudinal push rods 525 to move closer to or away from each other, thereby improving the efficiency of the FPC light bar calibration and improving the processing efficiency.

[0036] In order to improve the accuracy of calibration, a plurality of guide slots 526 are provided on the product placement block 521, and a push block 527 adapted to the guide slots 526 is provided on the transverse push rod 524. The push block 527 is arranged one-to-one with the guide slots 526, and the transverse clamping claw cylinder 522 can drive the push block 527 to slide in the guide slots 526; when the transverse clamping claw cylinder 522 is working, it drives the transverse push rod 524 to move, thereby driving the push block 527 to slide in the guide slots 526, and the movement direction of the push block 527 is limited and guided by the guide slots 526, so as to ensure that the push block 527 can push the FPC light bar on the product placement block 521 to slide horizontally. In this embodiment, the transverse direction calibrated by the transverse clamping claw cylinder 522 is the length direction of the FPC light bar. By setting a plurality of guide slots 526 and the push block 527, it can ensure that the length direction is accurately calibrated, thereby improving the processing accuracy.

[0037] In other embodiments, a longitudinal slot may also be provided on the product placement block 521 so that the longitudinal push rod 525 can slide in cooperation with the longitudinal slot, thereby limiting and guiding the driving direction of the longitudinal clamping cylinder 523 .

[0038] In order to limit the driving stroke of the transverse clamping cylinder 522, a transverse limit buffer 528 is installed on one of the transverse push rods 524; when the transverse clamping cylinder 522 drives the two transverse push blocks to move closer to each other, the transverse limit buffer 528 will abut against the other transverse push rod 524. At this time, the transverse push rod 524 also drives the push block 527 to calibrate the transverse position of the FPC light strip on the product placement block 521 to the preset position. The driving stroke of the transverse clamping cylinder 522 is limited by the transverse limit buffer 528 to prevent the transverse push rod 524 and the push block 527 from crushing the FPC light strip, thereby improving the stability of the work and ensuring the yield rate of processing.

[0039] In order to limit the driving stroke of the longitudinal clamping cylinder 523, a longitudinal limit buffer 529 is installed on one of the longitudinal push rods 525; when the longitudinal clamping cylinder 523 drives the two longitudinal push blocks to move closer to each other, the longitudinal limit buffer 529 will abut against the other longitudinal push rod 525. At this time, the longitudinal push rod 525 also calibrates the longitudinal position of the FPC light strip on the product placement block 521 to the preset position. The driving stroke of the longitudinal clamping cylinder 523 is limited by the longitudinal limit buffer 529 to prevent the longitudinal push rod 525 from crushing the FPC light strip, thereby improving the stability of the work and ensuring the yield rate of processing.

[0040] like Figure 1 As shown, a CCD component 8 is provided at a position on the machine base 1 corresponding to the feeding mechanism 3. 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 feeding mechanism 3 so as to obtain the position and orientation of the product on the feeding mechanism 3, and then control the first manipulator 6 to grab the product from the feeding mechanism 3. By setting the CCD component 8, the first manipulator 6 can accurately grab the product from the feeding mechanism 3, thereby improving the stability of the processing.

[0041] 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 feeding mechanism 3. The specific work is that the feeding mechanism 3 will transport the FPC light bar to the shooting position of the positioning camera 82, and the image of the FPC light bar is 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 feeding mechanism 3, and then control the first manipulator 6 to work, so that the first manipulator 6 adjusts the position and grasping angle to correspond to the position angle of the FPC light bar on the feeding mechanism 3, so that the first manipulator 6 can accurately grasp the FPC light bar from the feeding mechanism 3. By setting the positioning camera 82, the accuracy of feeding can be improved and the smooth processing can be guaranteed.

[0042] Working principle:

[0043] The backlight FPC light strip loader is placed on one side of the backlight automated assembly equipment, and the second manipulator 7 can move to the feeding position of the backlight automated assembly equipment; before processing, the product to be processed is placed on the feeding mechanism 3.

[0044] During processing, the feeding mechanism 3 is first controlled to work, and the FPC light strip is delivered to the grabbing position of the first manipulator 6; during this process, the FPC light strip will pass through the shooting area of ​​the positioning camera 82, and the positioning camera 82 will take a picture of it, so as to obtain information such as the position and orientation of the FPC light strip on the feeding mechanism 3. Then the grabbing and lateral movement module 4 is controlled to drive the first manipulator 6 to move to the top of the FPC light strip, and the manipulator rotation module 63 is controlled to drive the negative pressure suction plate 64 to rotate to the angle aligned with the FPC light strip on the feeding mechanism 3, and then the manipulator front and rear modules 61 and the manipulator lifting module 62 are respectively controlled to work, and the negative pressure suction plate 64 is driven to grab the FPC light strip from the feeding mechanism 3. Then, through the cooperation of the grabbing and lateral movement module 4, the manipulator front and rear modules 61, the manipulator lifting module 62 and the manipulator rotation module 63, the FPC light strip is placed on the calibration component 52 connected to the first manipulator 6.

[0045] Then the transverse clamping cylinder 522 and the longitudinal clamping cylinder 523 are controlled to work; the transverse clamping cylinder 522 will drive the two transverse push rods 524 to move in the direction close to the product placement block 521, and the transverse push rod 524 will drive the push block 527 to move, and the push block 527 will connect with the FPC light bar on the product placement block 521, and push the FPC light bar to move horizontally on the product placement block 521 until the transverse position of the FPC light bar is calibrated to the appropriate position; the longitudinal clamping cylinder 523 will drive the two longitudinal push rods 525 to move in the direction close to the product placement block 521, and the longitudinal push rod 525 will connect with the FPC light bar on the product placement block 521, 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 521, the external negative pressure device is used to make the product placement block 521 generate negative pressure suction, and the FPC light bar is firmly fixed on the product placement block 521. Then the transposition drive 53 is controlled to work, driving the calibration installation block 54 to rotate, thereby driving the two calibration components 52 to rotate synchronously, so that the positions of the two calibration components 52 are interchanged, and the product placement block 521 moves the FPC light bar to the grabbing position of the second manipulator 7, and then the horizontal clamping claw cylinder 522 and the longitudinal clamping claw cylinder 523 are controlled to reset; the horizontal clamping claw cylinder 522 will drive the horizontal push rod 524 to move away from the product placement block 521, so that the horizontal push rod 524 is separated from the FPC light bar; the longitudinal clamping claw cylinder 523 will drive the longitudinal push rod 525 to move away from the product placement block 521, so that the longitudinal push rod 525 is separated from the FPC light.

[0046] Then, the grabbing and traversing module 4 is controlled to drive the second manipulator 7 to move to the top of the FPC light bar on the calibration component 52; then, the manipulator front and rear modules 61, the manipulator lifting module 62 and the manipulator rotating module 63 are controlled to work respectively, and the negative pressure suction plate 64 is driven to grab the FPC light bar from the calibration component 52. Then, through the cooperation of the grabbing and traversing module 4, the manipulator front and rear modules 61, the manipulator lifting module 62 and the manipulator rotating module 63, 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.
