Description

Technical Field

[0001] This utility model relates to the field of display back panel processing technology, specifically to a metal plate loading device for display back panel processing. Background Technology

[0002] A monitor (or screen) is a computer's I / O device, i.e., an output device. It's a display tool that shows electronic files onto a screen via a specific transmission device. It can be categorized into cathode ray tube (CRT) monitors, plasma display panels (PDPs), and liquid crystal displays (LCDs). The backplate in a monitor primarily serves to support and protect internal electronic components, prevent dust intrusion, and provide physical support and heat dissipation.

[0003] Currently, most production lines still rely on manual handling and positioning, with each loading taking more than 30 seconds and involving repetitive labor, which restricts overall production efficiency. In some semi-automated production solutions that use robotic arms in conjunction with vacuum suction cups, the suction cup layout is fixed and cannot adapt to the size variations of different backplate models. This results in the need for manual repositioning after loading, extending the processing cycle. Furthermore, the positioning accuracy is low for different backplate models. Due to the mismatch between the adsorption point and the center of gravity of the plate, the plate is prone to swaying during the transfer process, and the end positioning error is large, which cannot meet the requirements of subsequent processing accuracy. In addition, due to the adhesion of oil film and the negative pressure effect, the failure rate of double-sheet adhesion is high when the robotic arm picks up the stacked ultra-thin metal plates, often resulting in two metal plates being loaded at once.

[0006] As a further preferred embodiment of this technical solution, two sets of vertically distributed bidirectional lead screws are rotatably installed inside the mounting base. The two sets of bidirectional lead screws are respectively configured to correspond to two sets of first adjusting rods and two sets of second adjusting rods. The two ends of the two sets of bidirectional lead screws pass through the corresponding two sets of first adjusting rods or second adjusting rods and are respectively threadedly connected to the corresponding two sets of first adjusting rods or second adjusting rods.

[0007] As a further preferred embodiment of this technical solution, two sets of vertically distributed bidirectional screws are rotatably installed inside the feeding rack. The two sets of bidirectional screws are respectively configured to correspond to two sets of first push rods and two sets of second push rods. The two ends of the two sets of bidirectional screws pass through the corresponding two sets of first push rods or two sets of second push rods and are threadedly connected to the corresponding first push rods or second push rods.

[0008] As a further preferred embodiment of this technical solution, a mounting rod is fixedly installed inside the mounting base, a first lifting rod is slidably installed inside the mounting rod, a second lifting rod is slidably installed inside the first lifting rod, the end of the second lifting rod away from the mounting rod is fixedly connected to the lifting base, a threaded rod is rotatably installed inside the mounting rod, a threaded tube is rotatably installed inside the first lifting rod, the threaded rod passes through the first lifting rod and is threadedly connected to the first lifting rod, and the threaded tube passes through the second lifting rod and is threadedly connected to the second lifting rod.

[0009] As a further preferred embodiment of this technical solution, the threaded rod has two sets of symmetrically distributed keyways, and the threaded tube has two sets of symmetrically distributed key blocks. The key blocks are arranged correspondingly to the keyways, and the threaded tube is slidably sleeved with the threaded rod through the key blocks and keyways.

[0010] As a further preferred embodiment of this technical solution, the feeding frame is slidably connected to the feeding rack via a slider, a sliding rod is fixedly installed inside the feeding rack, the slider and the sliding rod are slidably sleeved, two sets of symmetrically distributed springs are sleeved on the sliding rod, the two ends of the two sets of springs are fixedly connected to the slider and the feeding rack respectively, and a cam is rotatably installed on the feeding rack, the cam being fitted to the slider.

[0012] This utility model provides a metal plate loading device for processing display back panels, which has the following advantages:

[0013] (1) This utility model device achieves automatic and rapid positioning and gripping of metal backplates of different models of displays by means of adjustable limiting plates (controlled by the first and second adjusting rods driven by bidirectional screws) and adjustable adsorption mechanism (controlled by the first and second push rods driven by bidirectional screws to control the position of vacuum suction cups). It completely replaces the original manual handling and positioning process, significantly shortens the single loading time, effectively solves the problems of low efficiency and high labor intensity of manual operation, and greatly improves the overall production efficiency. Among them, the bidirectional screw drives four sets of limiting plates to perform symmetrical synchronous adjustment, and the bidirectional screw drives four sets of vacuum suction cups to perform symmetrical synchronous adjustment, so that the limiting range and adsorption point can accurately match metal backplates of different length and width dimensions. It overcomes the shortcomings of traditional fixed-layout suction cup devices that cannot adapt to different types of boards. After loading, no manual secondary adjustment of positioning is required, ensuring the stability and continuity of the processing cycle. Moreover, the four sets of independently adjustable vacuum suction cups can flexibly adjust the distribution of the adsorption points according to the current size of the board, ensuring that the adsorption force application point is always close to or located in the center of gravity area of ​​the board. This avoids the problem of board swaying during the transfer process caused by the mismatch between the adsorption point and the center of gravity, improves the end positioning accuracy, and meets the needs of subsequent high-precision processing.

[0014] (2) This utility model, through the sliding design of the feeding frame on the feeding rack and the lifting setting of the first lifting rod and the second lifting rod on the lifting seat, enables the device to achieve stable separation and sequential lifting and absorption of stacked metal plates. Through the lifting force control, the vibration or micro-motion of the feeding frame driven by the cam and the buffer reset effect of the spring, the double-sheet adhesion problem caused by oil film adhesion and negative pressure effect of ultra-thin metal plates is effectively overcome, and the failure rate of double-sheet feeding is greatly reduced.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figures 1-6As shown in this embodiment, a metal plate feeding device for display back panel processing includes a mounting base 1. The device is characterized by: a lifting base 2 above the mounting base 1; a feeding frame 3 rotatably mounted above the mounting base 1; a feeding frame 4 slidably mounted on the feeding frame 3; four sets of symmetrically distributed limiting plates 5 above the mounting base 1; two sets of symmetrically distributed first adjusting rods 6 slidably mounted inside the mounting base 1; two sets of symmetrically distributed second adjusting rods 7 slidably mounted inside the mounting base 1; the two sets of first adjusting rods 6 and second adjusting rods 7 are perpendicularly distributed; the four sets of limiting plates 5 are slidably connected to the corresponding set of first adjusting rods 6 and set of second adjusting rods 7; and four sets of symmetrically distributed pushing frames 9 are provided inside the feeding frame 4, each of which is fixedly equipped with a vacuum suction cup 13. Two sets of symmetrically distributed first push rods 10 are slidably installed inside the feeding frame 4, and two sets of symmetrically distributed second push rods 11 are slidably installed inside the feeding frame 4. The two sets of first push rods 10 and second push rods 11 are perpendicular to each other. Four sets of push frames 9 are slidably connected to the corresponding set of first push rods 10 and the corresponding set of second push rods 11. Two sets of vertically distributed bidirectional screws 8 are rotatably installed inside the mounting base 1. The two sets of bidirectional screws 8 are respectively set to correspond to the two sets of first adjusting rods 6 and the two sets of second adjusting rods 7. The two ends of the two sets of bidirectional screws 8 pass through the corresponding two sets of first adjusting rods 6 or second adjusting rods 7 and are threadedly connected to the corresponding two sets of first adjusting rods 6 or second adjusting rods 7. Two sets of vertically distributed bidirectional screws 12 are rotatably installed inside the feeding frame 3. The screws 12 are respectively configured with two sets of first push rods 10 and two sets of second push rods 11. The two ends of the two sets of bidirectional screws 12 pass through the corresponding two sets of first push rods 10 or two sets of second push rods 11 and are threadedly connected to the corresponding first push rods 10 or second push rods 11. The rotation of the two sets of bidirectional screws 8 in the mounting base 1 causes the two sets of first adjusting rods 6 and two sets of second adjusting rods 7 in the mounting base 1 to slide synchronously inward or outward under the limiting action of the mounting base 1. This allows the spacing between the four sets of limiting plates 5 in the mounting base 1 to be adjusted according to the specifications of the metal plate waiting to be loaded, so that the four sets of adjusting plates are located at the four corners of the metal plate, regulating the state of the metal plate during the waiting process for loading. The rotation of the two sets of bidirectional screws 12 in the loading frame 4 is synchronized. Adjusting the distance between the two sets of first push rods 10 and the two sets of second push rods 11 allows the four sets of push frames 9 to slide synchronously inward or outward. Adjusting the distance between the four sets of vacuum suction cups 13 allows them to adapt to metal plates of different specifications, ensuring that the suction force point of the vacuum suction cups 13 is always close to or located in the center of gravity area of ​​the plate. This avoids plate swaying during transport due to mismatch between the suction point and the center of gravity, improving end-positioning accuracy and meeting the requirements of subsequent high-precision processing. Adjusting the distance between the four sets of limiting plates 5 and the four sets of push frames 9 allows the feeding device to precisely match the limiting range and suction point of the metal plate with metal back plates of different lengths and widths, overcoming the shortcomings of traditional fixed-layout suction cup devices that cannot adapt to different types of plates.Furthermore, no manual repositioning is required after material loading, ensuring the stability and continuity of the processing cycle.

[0024] like Figure 3 , Figure 4 and Figure 6 As shown, a mounting rod 14 is fixedly installed inside the mounting base 1. A first lifting rod 15 is slidably installed inside the mounting rod 14. A second lifting rod 16 is slidably installed inside the first lifting rod 15. The end of the second lifting rod 16 away from the mounting rod 14 is fixedly connected to the lifting base 2. A threaded rod 17 is rotatably installed inside the mounting rod 14. A threaded tube 19 is rotatably installed inside the first lifting rod 15. The threaded rod 17 passes through the first lifting rod 15 and is threadedly connected to it. The threaded tube 19 passes through the second lifting rod 16 and is threadedly connected to it. Two sets of symmetrically distributed keyways 18 are provided inside the threaded rod 17. Two sets of symmetrically distributed key blocks 20 are provided inside the threaded tube 19. The key blocks 20 and the key... The groove 18 is correspondingly set, and the threaded tube 19 is slidably sleeved with the threaded rod 17 through the key block 20 and the keyway 18. The feeding frame 4 is slidably connected to the feeding rack 3 through the slider 21. A slide rod 22 is fixedly installed inside the feeding rack 3. The slider 21 is slidably sleeved with the slide rod 22. Two sets of symmetrically distributed springs 23 are sleeved on the slide rod 22. The two ends of the two sets of springs 23 are fixedly connected to the slider 21 and the feeding rack 3, respectively. A cam 24 is rotatably installed on the feeding rack 3. The cam 24 is fitted with the slider 21. A gear 25 is sleeved on the feeding rack 3. A rack 26 is slidably installed inside the mounting base 1. A cylinder 27 is fixedly installed inside the mounting base 1. The rack 26 is fixedly connected to the output end of the piston rod of the cylinder 27. Strip 26 meshes with gear 25. Based on the actual thickness of the metal backing plate awaiting loading, the motor in mounting rod 14 starts, driving threaded rod 17 to rotate. Under the limiting action of mounting rod 14, the first lifting rod 15 and the second lifting rod 16 slide. Simultaneously, under the limiting action of key block 20 and keyway 18, threaded tube 19 rotates synchronously with threaded rod 17. Then, under the limiting action of the first lifting rod 15, the second lifting rod 16 slides. Lifting seat 2 drives multiple sets of metal plates above to move synchronously upwards by the thickness of one metal plate. The uppermost metal plate adheres to multiple sets of vacuum suction cups 13. After the multiple sets of vacuum suction cups 13 in loading frame 4 adsorb the surface of the metal plate, the loading rack 3... The motor drives the cam 24 to rotate, and the cam 24 pushes the slider 21, causing the slider 21 to slide the feeding frame 4 on the feeding rack 3. It also squeezes or stretches the spring 23 on the slide rod 22. The cooperation of the spring 23, the slide rod 22 and the cam 24 causes the feeding frame 4 to slide back and forth in the feeding rack 3 after the metal plate is adsorbed and fixed. This overcomes the problem of double-sheet adhesion caused by oil film adhesion and negative pressure effect of ultra-thin metal plates. During the shaking process, the lower metal plate is blocked by the limiting plate 5 and cannot slide synchronously with the upper adsorbed metal plate with the upper feeding frame 4 due to the negative pressure effect. This causes the two sets of metal plates adsorbed due to the negative pressure effect to separate, which greatly reduces the failure rate of double-sheet feeding.

[0025] This utility model provides a metal plate loading device for display back panel processing. The specific working principle is as follows: The rotation of two sets of bidirectional lead screws 8 in the mounting base 1, under the limiting action of the mounting base 1, causes the two sets of first adjusting rods 6 and two sets of second adjusting rods 7 within the mounting base 1 to slide synchronously inward or outward. This adjusts the spacing between the four sets of limiting plates 5 within the mounting base 1 according to the specifications of the metal plate awaiting loading, positioning the four adjusting plates at the four corners of the metal plate and regulating its state during loading. Simultaneously, the rotation of two sets of bidirectional screws 12 in the loading frame 4 adjusts the spacing between the two sets of first push rods 10 and the two sets of second push rods 11, thereby causing the four sets of push rods to... 9. The four sets of vacuum suction cups 13 slide inward or outward simultaneously, adjusting the distance between them to accommodate metal plates of different specifications. This ensures that the suction force of the vacuum suction cups 13 always applies close to or is located in the center of gravity area of ​​the plate, avoiding plate swaying during transport due to mismatch between the suction point and the center of gravity. This improves end-positioning accuracy and meets the requirements of subsequent high-precision processing. The adjustment of the distance between the four sets of limiting plates 5 and the four sets of pushing frames 9 allows the feeding device to accurately match the limiting range and suction point of the metal plate with metal back plates of different lengths and widths. This overcomes the shortcomings of traditional fixed-layout suction cup devices that cannot adapt to different types of plates, and eliminates the need for manual secondary adjustment of positioning after feeding. This ensures the stability and continuity of the processing cycle. Based on the actual thickness of the metal back plate waiting to be loaded, the motor in the mounting rod 14 starts and drives the threaded rod 17 to rotate. Under the limiting action of the mounting rod 14, the first lifting rod 15 and the second lifting rod 16 slide. Simultaneously, under the limiting action of the key block 20 and the keyway 18, the threaded tube 19 rotates synchronously with the threaded rod 17. Then, under the limiting action of the first lifting rod 15, the second lifting rod 16 slides. The lifting seat 2 drives the multiple sets of metal plates above to move up synchronously by the thickness of one metal plate. The uppermost metal plate is attached to the multiple sets of vacuum suction cups 13. After the multiple sets of vacuum suction cups 13 in the loading frame 4 adsorb the surface of the metal plate, the loading rack... The motor in step 3 drives the cam 24 to rotate. The cam 24 pushes the slider 21, causing the slider 21 to slide the feeding frame 4 on the feeding rack 3. It also squeezes or stretches the spring 23 on the slide rod 22. The cooperation of the spring 23, the slide rod 22 and the cam 24 causes the feeding frame 4 to slide back and forth in the feeding rack 3 after the metal plate is adsorbed and fixed. This overcomes the problem of double-sheet adhesion caused by oil film adhesion and negative pressure effect of ultra-thin metal plates. During the shaking process, the lower metal plate is blocked by the limiting plate 5 and cannot slide synchronously with the upper adsorbed metal plate with the upper feeding frame 4 due to the negative pressure effect. This causes the two sets of metal plates adsorbed due to the negative pressure effect to separate, which greatly reduces the failure rate of double-sheet feeding.
