Description

Technical Field

[0001] The present invention belongs to the technical field of device detection, in particular to an FCOB maintenance method and maintenance equipment thereof. Background Art

[0002] At present, the FCOB post-furnace dead light test and maintenance are operated by a device. After the material is moved to the AOI inspection area, the cylinder and software control will control the test needle plate to automatically press down, and the probe of the test needle plate will be used to energize the inspection material to achieve the effect of lighting up the inspection material. Then, the camera in the AOI inspection area is used to scan and inspect, so as to scan out whether there is a dead light position, and then carry out processing work.

[0003] Since a cylinder is used to control the downward pressure of the test needle plate, it is difficult to stop the probe of the test needle plate in time when it contacts the material plate. It is easily affected by the extrusion reaction force. The probe part is very likely to bend and deform after long-term use, which may lead to the problem of probe position displacement or probe breakage, so improvement is needed. Summary of the Invention

[0004] In view of the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: a FCOB maintenance method, firstly transporting the material into the AOI inspection area I through a conveyor belt, where the test needle plate is automatically pressed down by a cylinder and software control, and then the AOI inspection area I scans and detects the material that is powered on and lit through a camera, and then detects the dead light area, and then uses a robotic arm to spot weld the chip in the dead light area to combine the chip and the plate, and fill the dead light area by welding the chip, and then the AOI inspection area I scans and detects the lit material again through a camera, and then transfers the material to the AOI inspection area II for secondary inspection. After the inspection is completed, the material is transferred to the discharge port for discharge to obtain the repaired material.

[0005] Furthermore, the FCOB maintenance equipment includes a horizontal conveyor belt, and transport shafts are symmetrically provided on the left and right sides of the horizontal conveyor belt, and a detection component is provided in the middle of the horizontal conveyor belt.

[0006] The detection component includes a horizontal slide rail, and sliding vertical plates are symmetrically arranged on the front and rear sides of the inner wall of the detection component. The horizontal slide rail can control the sliding vertical plate to perform horizontal sliding movement through the push plate inside it. The inner cavity of the sliding vertical plate is fixedly connected to the vertical guide rail, and the upper part of the inner wall of the vertical guide rail is slidably connected to the detection component. A buffer component is arranged inside the detection component, and a scanning component is arranged on the lower surface of the detection component.

[0007] The beneficial effects of the present invention are as follows: the device improves the probe part of the general test needle plate, and uses a guide rod to energize the guide contact part of the material to realize the work of lighting the material lamp bead. Since the detection component is difficult to stop in time when moving to the specified position, the guide rod is easily subjected to the extrusion reaction force when contacting the material. The probe part is very likely to bend and deform after long-term use, which may lead to the problem of probe position offset or probe breakage. The guide rod of the device will bend to the side close to the transfer arm at the moment of contact, thereby greatly improving the impact resistance of the guide rod and avoiding the above-mentioned problems.

[0008] Furthermore, the detection component includes a protective shell, the bottom of the inner wall of the protective shell is fixedly connected to a containing box, and rotating joints are symmetrically fixed on both sides of the lower surface of the protective shell, the outer surface of the rotating joint is fixedly connected to a transfer arm, the bottom end of the transfer arm is rotatably connected to a conducting joint, the outer surface of the conducting joint is rotatably connected to a conducting rod, and the inner cavity of the transfer arm is fixedly connected to the inner cavity of the conducting joint through a built-in wire, and the inner cavity of the conducting rod is also fixedly connected to the inner cavity of the conducting joint through a built-in wire, the protective shell supplies power to the inside of the rotating joint through the wire in the inner cavity, and then supplies power to the conducting rod through the wire inside the transfer arm and the conducting joint, and then the conducting rod supplies power to the energized end part of the material plate.

[0009] Furthermore, the front and rear sides of the outer surface of the protective shell are fixedly connected with plug-in outer plates, and the side of the outer surface of the plug-in outer plate away from the protective shell is slidingly connected to the inner wall of the vertical guide rail, the inner cavity of the rotating joint is fixedly connected to the inner cavity of the protective shell through the guide rod, and the upper part of the outer surface of the guide rod is rotatably connected to the outer surface of the transfer arm through an arc spring belt.

[0010] Furthermore, the scanning component includes a control slide rail, active rollers are symmetrically provided on both sides of the inner cavity of the control slide rail, and a traction slide bar is slidably connected to the middle of the inner wall of the control slide rail. The control slide rail rotates the active roller to drive the traction slide bar to slide along the inner wall of the control slide rail by rolling friction. The bottom end of the traction slide bar is rotatably connected to a cluster lens shell, and a number of scanning lenses are provided on the inner wall of the cluster lens shell for detecting bad area locations. Side spray components are symmetrically provided on the front and back sides of the inner wall of the cluster lens shell.

[0011] Furthermore, both sides of the upper surface of the cluster lens shell are slidably connected to the limiting slide rails through the inserted rods. There are two limiting slide rails, and the upper surfaces of the limiting slide rails are fixedly connected to the lower surface of the storage box. When the traction slide bar drives the cluster lens shell to slide left and right, it itself will also rotate relative to the cluster lens shell. Therefore, the cluster lens shell needs to be restricted by the limiting slide rails on both sides to prevent itself from deflecting under the control of the traction slide bar, resulting in the problem that the lens cannot scan stably. The outer surface of the active roller is rollingly connected to the top of the outer surface of the traction slide bar, and the upper surface of the control slide rail is fixedly connected to the lower surface of the storage box.

[0012] After adopting the above-mentioned further structure, the cluster lens shell of the device can move in a larger range under the control of the control slide rail, thereby increasing the actual scanning range of the lens. Since the cluster lens shell is driven to slide by the rotating traction slide bar, limit slide rails are added on both sides to prevent the cluster lens shell from deflecting, thereby ensuring the stability of the camera during operation and avoiding the problem of missing bad areas.

[0013] Furthermore, the side spray component includes an inverted arch shell, the outer surface of the inverted arch shell is slidably connected to the inner wall of the cluster lens shell, and through spray holes are symmetrically provided on the front and rear sides of the inner cavity of the inverted arch shell. Both sides of the top of the inverted arch shell are fixedly connected with elastic connecting tubes, and the top of the elastic connecting tube is fixedly connected with a power spray box. The power spray box can pressurize the inside of the inverted arch shell through the hollow elastic connecting tube, and then the inverted arch shell sprays outward through the through spray holes on both sides. The upper surface of the power spray box is fixedly connected to the lower surface of the containing box.

[0014] After adopting the above-mentioned further structure, during the downward movement of the cluster lens shell, the inverted arch shell that slides up and down by inertia can perform a more comprehensive scanning of the lens part of the cluster lens shell through the penetrating nozzle, thereby blowing to the part of the lens that is biased towards the bottom, thereby more comprehensively removing dust and impurities on the lens, and preventing the problem of dust accumulation affecting the scanning work due to the lens not being cleaned for a long time.

[0015] Furthermore, the buffer component includes a vertical guide rod, a counterweight slip ring slidably connected to the middle portion of the outer surface of the vertical guide rod, buffer springs symmetrically disposed on the upper and lower sides of the outer surface of the counterweight slip ring, the end of the buffer spring remote from the counterweight slip ring fixedly connected to a pressure-sensitive pad tube, transfer plates symmetrically secured to the front and rear sides of the inner cavity of the pressure-sensitive pad tube, and a receiver fixedly connected to the end of the transfer plate remote from the pressure-sensitive pad tube. Both ends of the vertical guide rod are fixedly connected to the axis of the inner cavity of the pressure-sensitive pad tube, the outer surface of the pressure-sensitive pad tube is fixedly connected to the inner wall of the storage box, the outer surface of the receiver is fixedly connected to the inner wall of the storage box, and the axis of the inner wall of the counterweight slip ring is slidably connected to the outer surface of the vertical guide rod via a ball bearing.

[0016] After adopting the above-mentioned further structure, when the protective shell slides up and down, the buffer component located inside the receiving box is also working. At this time, the counterweight slip ring on the outer surface of the vertical guide rod will slide along the vertical guide rod under the action of inertia, thereby triggering the pressure-sensitive pad tube by pressing the buffer spring, and utilizing the extrusion force exerted on the pressure-sensitive pad tube to more intuitively feedback the inertial force of the protective shell, thereby ensuring that the sliding speed of the detection component can be controlled within a relatively stable range, ensuring the advancement speed of the detection component while reducing the impact force exerted on the guide rod.

DETAILED DESCRIPTION

[0026] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0027] Example 1, please refer to Figure 1-Figure 5 The present invention provides a technical solution: a FCOB maintenance method, firstly, the material is transported into the AOI inspection area I through a conveyor belt, and the test needle plate here is automatically pressed down by the cylinder and software control, and then the AOI inspection area I scans and detects the material that is powered on and lit through the camera, and then detects the dead light area, and then the chip is spot welded in the dead light area through the robot arm to combine the chip and the plate, and the dead light area is filled by welding the chip, and then the AOI inspection area I scans and detects the lit material again through the camera, and then transfers the material to the AOI inspection area II for secondary inspection. After the inspection is completed, the material is transferred to the discharge port to obtain the repaired material.

[0028] The FCOB maintenance equipment includes a horizontal conveyor belt 1 , with conveyor shafts 2 symmetrically arranged on the left and right sides of the horizontal conveyor belt 1 , and a detection component 3 arranged in the middle of the horizontal conveyor belt 1 .

[0029] The detection component 3 includes a horizontal slide rail 32, and sliding vertical plates 31 are symmetrically arranged on the front and rear sides of the inner wall of the detection component 3. The horizontal slide rail 32 can control the sliding vertical plate 31 to perform horizontal sliding movement through the push plate inside it. The inner cavity of the sliding vertical plate 31 is fixedly connected to the vertical guide rail 33, and the upper part of the inner wall of the vertical guide rail 33 is slidably connected to the detection component 4. The interior of the detection component 4 is provided with a buffer component 5, and the lower surface of the detection component 4 is provided with a scanning component 6.

[0030] The detection component 4 includes a protective shell 41, the bottom of the inner wall of the protective shell 41 is fixedly connected to a containing box 42, and rotating joints 44 are symmetrically fixed on both sides of the lower surface of the protective shell 41, and the outer surface of the rotating joint 44 is fixedly connected to a transfer arm 45, and the bottom end of the transfer arm 45 is rotatably connected to a conducting joint 46, and the outer surface of the conducting joint 46 is rotatably connected to a conducting rod 47, and the inner cavity of the transfer arm 45 is fixedly connected to the inner cavity of the conducting joint 46 through a built-in wire, and the inner cavity of the conducting rod 47 is also fixedly connected to the inner cavity of the conducting joint 46 through a built-in wire. The protective shell 41 supplies power to the inside of the rotating joint 44 through the wire in the inner cavity, and then supplies power to the conducting rod 47 through the wire inside the transfer arm 45 and the conducting joint 46, and then the conducting rod 47 supplies power to the energized end part of the material plate.

[0031] The front and rear sides of the outer surface of the protective shell 41 are fixedly connected with plug-in outer plates 43, and the side of the outer surface of the plug-in outer plate 43 away from the protective shell 41 is slidingly connected to the inner wall of the vertical guide rail 33. The inner cavity of the rotating joint 44 is fixedly connected to the inner cavity of the protective shell 41 through the guide rod, and the upper part of the outer surface of the guide rod 47 is rotatably connected to the outer surface of the transfer arm 45 through the arc spring belt 48.

[0032] The scanning component 6 includes a control slide rail 61, and active rollers 62 are symmetrically arranged on both sides of the inner cavity of the control slide rail 61. The middle part of the inner wall of the control slide rail 61 is slidably connected to a traction slide bar 63. The control slide rail 61 rotates the active roller 62 to drive the traction slide bar 63 to slide along the inner wall of the control slide rail 61 by using rolling friction. The bottom end of the traction slide bar 63 is rotatably connected to a cluster lens shell 64. Several scanning lenses are arranged on the inner wall of the cluster lens shell 64 for detecting bad area locations. Side spray components 7 are symmetrically arranged on the front and back sides of the inner wall of the cluster lens shell 64.

[0033] Both sides of the upper surface of the clustering lens shell 64 are slidably connected to the limiting slide rails 65 through the inserted rods. There are two limiting slide rails 65, and the upper surface of the limiting slide rails 65 is fixedly connected to the lower surface of the storage box 42. When the traction slide bar 63 drives the clustering lens shell 64 to slide left and right, it will also rotate relative to the clustering lens shell 64. Therefore, the clustering lens shell 64 needs to be restricted by the limiting slide rails 65 on both sides to prevent itself from being deflected under the control of the traction slide bar 63, resulting in the problem of the lens being unable to scan stably. The outer surface of the active roller 62 is rollingly connected to the top of the outer surface of the traction slide bar 63, and the upper surface of the control slide rail 61 is fixedly connected to the lower surface of the storage box 42.

[0034] Place the plate to be inspected at the left end of the horizontal conveyor belt 1. Under the control of the transport shaft 2, transport the material to the area where the inspection component 3 is located. Then stop the horizontal conveyor belt 1 and carry out the inspection.

[0035] The vertical guide rails 33 on both sides pull the protective shell 41 downward by pulling and plugging the outer plate 43, so that the guide rod 47 at the bottom is connected to the guide point of the material below, and then the material is energized. Since the overall mass of the detection component 4 is large, during the downward sliding of the detection component 4, the guide rod 47 at the bottom will be subjected to a large impact force at the moment of contact with the material, and the detection component 4 may continue to slide down, causing the guide rod 47 to continue to be pressed down, so at this time the guide rod 47 will bend to the side close to the transfer arm 45, and the arc-shaped spring belt 48 absorbs the impact force, thereby avoiding damage to the guide rod 47, and the device is mainly energized by the wire inside the rod body, so it can be energized normally when the guide rod 47 is deflected and bent.

[0036] Example 2, please refer to Figures 1-8 The present invention provides a technical solution: on the basis of Example 1, the side spray component 7 includes an inverted arch shell 71, the outer surface of the inverted arch shell 71 is slidably connected to the inner wall of the cluster lens shell 64, and through-spray holes 72 are symmetrically provided on the front and rear sides of the inner cavity of the inverted arch shell 71. Both sides of the top of the inverted arch shell 71 are fixedly connected with elastic connecting tubes 73, and the top of the elastic connecting tube 73 is fixedly connected with a power spray box 74. The power spray box 74 can pressurize the inside of the inverted arch shell 71 through the hollow elastic connecting tube 73, and then the inverted arch shell 71 sprays outward through the through-spray holes 72 on both sides. The upper surface of the power spray box 74 is fixedly connected to the lower surface of the accommodating box 42.

[0037] The buffer component 5 includes a vertical guide rod 51. A counterweight slip ring 52 is slidably connected to the middle of the outer surface of the vertical guide rod 51. Buffer springs 53 are symmetrically arranged on the upper and lower sides of the outer surface of the counterweight slip ring 52. The end of the buffer spring 53 away from the counterweight slip ring 52 is fixedly connected to a pressure-sensitive pad 54. Transfer plates 55 are symmetrically fixed to the front and rear sides of the inner cavity of the pressure-sensitive pad 54. The end of the transfer plate 55 away from the pressure-sensitive pad 54 is fixedly connected to a receiver 56. Both ends of the vertical guide rod 51 are fixedly connected to the axis of the inner cavity of the pressure-sensitive pad 54. The outer surface of the pressure-sensitive pad 54 is fixedly connected to the inner wall of the storage box 42. The outer surface of the receiver 56 is fixedly connected to the inner wall of the storage box 42. The inner wall of the counterweight slip ring 52 is slidably connected to the outer surface of the vertical guide rod 51 at the axis via a ball bearing.

[0038] After the material is energized, the bad area will be detected by the scanning component 6 under the receiving box 42, and the control slide rail 61 will drive the traction slide bar 63 to slide left and right through the active roller 62 on the inner wall, thereby completely scanning the material below. After the scanning is completed, the sliding vertical plate 31 will be offset to the side according to the positioning obtained by the beam lens shell 64, and then the chip will be spot welded at the bad area position through the repair welding equipment, and then the repair welding equipment will be removed, and the device will be powered on again, and the beam lens shell 64 will be used to detect whether there is a bad area position. After the detection is completed, the detection component 4 will be lifted up, the transport shaft 2 will be started, and the material will be moved away.

[0039] When the protective shell 41 moves downward, the inverted arch shell 71 will slide down synchronously with the cluster lens shell 64. However, when the scanning component 6 stops moving, the inverted arch shell 71 will slide relative to the inner wall of the cluster lens shell 64 due to inertia, and will shake up and down continuously under the elastic traction of the elastic connecting tube 73. At this time, the power spray box 74 sprays air to clean all the scanning lenses facing the inside of the cluster lens shell 64 through the through spray hole 72 of the inverted arch shell 71.

[0040] When the protective shell 41 slides up and down, the buffer component 5 located inside the accommodating box 42 is also working. At this time, the counterweight slip ring 52 on the outer surface of the vertical guide rod 51 will slide along the vertical guide rod 51 under the action of inertia, thereby triggering the pressure-sensitive pad tube 54 by pressing the buffer spring 53. The extrusion force exerted on the pressure-sensitive pad tube 54 is used to more intuitively feedback the inertial force of the protective shell 41, thereby ensuring that the sliding speed of the detection component 4 can be controlled within a relatively stable range, ensuring the advancement speed of the detection component 4 while reducing the impact force exerted on the guide rod 47.

[0041] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
