[0002] Existing PCB loading mechanisms generally use robotic arms or levers to push circuit boards into the conveyor line. Due to factors such as friction, angle deviation, and vibration, the boards are prone to warping, slippage, or scratches. In particular, thin boards, large-size boards, or flexible boards are more prone to sagging deformation when they lack rigidity, resulting in deviation of the insertion angle or even board jamming. Summary of the Invention

[0003] In order to improve the defects of existing PCB board feeding mechanisms that directly push PCB boards for feeding, resulting in board warping, slippage or scratches, this application provides a floating support conveying feeding device.

[0004] The floating support conveyor feeding device provided in this application adopts the following technical solution: A floating support conveying loading device includes a conveying platform with a conveying trough for placing and conveying PCB boards; a floating support conveying mechanism disposed on the conveying platform for generating an air film at the bottom of the conveying trough to float and support the PCB boards in the conveying trough; a guiding adjustment mechanism disposed within the conveying trough for guiding the PCB boards in the conveying trough and adjusting the loading angle of the PCB boards; a vision inspection mechanism disposed on the conveying platform for visually inspecting the PCB boards on the conveying trough to drive the guiding adjustment mechanism to adjust and correct the loading angle of the PCB boards; and an attitude detection mechanism disposed on the conveying platform for attitude detection of the sides of the PCB boards on the conveying trough to adjust the magnitude of the air film pressure generated by the floating support conveying mechanism.

[0005] By adopting the above technical solution, during use, the PCB board is placed on the conveyor trough for feeding. The air film generated at the bottom of the trough by the floating support conveyor mechanism floats and supports the PCB board, effectively eliminating the influence of mechanical friction and vibration, avoiding board slippage and displacement, improving feeding stability, and reducing direct contact friction during feeding to prevent scratches, indentations, or bending deformation. It is particularly suitable for thin boards, flexible boards, and large-size PCBs, protecting the integrity of the board surface. At the same time, a guide adjustment mechanism is set up. The visual inspection mechanism performs visual inspection on different PCBs to drive the guide adjustment mechanism to adjust and correct the feeding angle of the PCB board, correct the board entry posture, and ensure the smooth introduction of the PCB board. In addition, this application sets up a posture detection mechanism to detect the posture of the side of the PCB board. According to the different thicknesses of the PCB board, the air film pressure generated by the floating support conveyor mechanism is adjusted to maintain the balanced posture of PCB boards of different thicknesses during the feeding process.

[0006] Preferably, the floating support conveying mechanism includes a plurality of air outlets arranged in a matrix on the bottom of the conveying trough.

[0007] By adopting the above technical solution, the airflow generated by the vacuum generator is ejected from the air outlet nozzle, and the air outlet nozzle is set at an angle along the board conveying direction, which provides air-float support and conveying for the PCB board, realizing pneumatic conveying, effectively eliminating the influence of mechanical friction and vibration, and avoiding board slippage and displacement; and reducing direct contact friction during the feeding process to prevent scratches, indentations or bending deformation, which is particularly suitable for thin boards, flexible boards and large-size PCBs.

[0008] Preferably, the floating support conveying mechanism further includes an air outlet nozzle, and the attitude detection mechanism includes laser rangefinders located on both sides of the conveying platform.

[0011] By adopting the above technical solution, the distance between the first guide plate and the second guide plate, as well as the position of the discharge port, can be adjusted according to the PCB board of different widths, so that the discharge port is aligned with the feeding groove, avoiding deviation of the entry angle or even jamming of the board.

[0012] Preferably, the first adjustment component includes: a first guide post disposed on the conveying platform along the movement direction of the first guide plate; a first guide member, one end of which is connected to the first guide plate and the other end of which is movably sleeved on the first guide post; and a first adjustment drive member disposed on the conveying platform and whose drive end is connected to the first guide plate.

[0013] By adopting the above technical solution, the first adjustment drive component can be a telescopic cylinder, which controls the reciprocating movement of the first guide plate by telescopic movement, and the first guide post and the first guide component are slidably engaged to make the movement of the first guide component stable.

[0014] Preferably, the second adjustment component includes: a second guide post disposed on the conveying platform along the movement direction of the second guide plate; a second guide member, one end of which is connected to the second guide plate and the other end of which is movably sleeved on the second guide post; and a second adjustment drive member disposed on the conveying platform with its drive end connected to the second guide plate.

[0015] By adopting the above technical solution, the second adjustment drive component can be a telescopic cylinder.

The second guide post and the second guide component are slidably engaged to make the movement of the second guide component stable.

[0016] Preferably, the guide adjustment mechanism further includes: an adjustment mounting component, which is disposed on the conveying platform and extends into the conveying trough at one end; a swing adjustment rod, one end of which is hinged to the end of the adjustment mounting component extending into the conveying trough; and a swing drive component, which is disposed on the conveying platform and whose drive end is connected to the swing adjustment rod, for driving the swing adjustment rod to swing so as to adjust the loading angle of the PCB board on the conveying trough.

[0017] By adopting the above technical solution, the swing drive component uses a telescopic cylinder, which drives the swing adjustment rod to swing through the telescopic end of the telescopic cylinder to adjust the PCB board's slot angle.

[0018] Preferably, it further includes a flipping feeding mechanism, which includes: a rotating roller rotatably mounted on a conveying platform; a flipping drive for driving the rotating roller to rotate; feeding support limit strips, a plurality of feeding support limit strips arranged circumferentially along the rotating roller, and a feeding groove formed between two adjacent feeding support limit strips; the guiding adjustment mechanism is used to guide the PCB board in the conveying groove and adjust the entry angle of the PCB board when it enters the feeding groove.

[0019] By adopting the above technical solution, the PCB board in the conveying trough is guided by the guiding adjustment mechanism and the entry angle of the PCB board into the feeding trough is adjusted so that the PCB board enters the feeding trough stably. The feeding support limit strip provides support and limit. During the flipping process, the fan dissipates heat and dries the PCB board.

[0020] Preferably, the visual inspection mechanism includes a first inspection mounting component and a first inspection camera disposed on the first inspection mounting component and corresponding to the conveying trough. The visual inspection mechanism also includes a second inspection mounting component disposed in front of the first inspection mounting component along the conveying direction and a second inspection camera disposed on the second inspection mounting component and corresponding to the conveying trough. A flipping material picking structure is provided between the second inspection camera and the conveying trough. The flipping material picking structure is used to pick up the PCB board on the conveying trough and flip the PCB board 180° so that the bottom surface of the PCB board faces the second inspection camera.

[0021] By adopting the above technical solution, when the PCB board is loaded into the feeding trough, the first detection camera detects the front of the PCB board to obtain information such as the width of the PCB board, so as to adjust the distance between the first guide plate and the second guide plate. When the PCB board is conveyed to the underside of the flipping material picking structure, the flipping material picking structure picks it up and flips it 180° so that the bottom surface of the PCB board faces the second detection camera. The second detection camera detects the bottom surface of the PCB board. If damage is found, an alarm is triggered in time to remove the defective product. If the detection is qualified, the board is reset and flipped 180° so that the bottom surface of the PCB board faces down and is placed back on the feeding trough.

[0022] Preferably, the flipping material handling structure includes a flipping mounting frame, a flipping shaft rotatably mounted on the flipping mounting frame, an adsorption member mounted on the flipping shaft, and a flipping drive mechanism for driving the flipping shaft to flip. The flipping drive mechanism includes: a drive mounting base mounted on the flipping mounting frame; a drive slider movably mounted on the drive mounting base, the drive slider having an arc-shaped groove; a flipping linkage member, one end of which is eccentrically connected to the flipping shaft, and the other end having a linkage end, the linkage end extending into the arc-shaped groove and capable of moving along the arc-shaped groove; two elastic pushers, two of which are mounted on the drive slider and respectively extend into both ends of the arc-shaped groove, the linkage end being capable of moving along the arc-shaped groove to both ends of the arc-shaped groove and compressing the elastic pushers; and a flipping drive member mounted on the flipping mounting frame for driving the drive slider to move.

[0023] By adopting the above technical solution, during use, the flipping drive component drives the drive slider to move on the drive mounting base. The movement of the drive slider is the movement of the arc-shaped slide groove, which in turn pushes the linkage end extending into the arc-shaped slide groove to move along the arc-shaped slide groove, thereby driving the flipping linkage component to rotate, so as to realize the flipping shaft flipping. When the bottom surface of the PCB board faces the second detection camera, the linkage end is located at one end of the arc-shaped slide groove and compresses the elastic pusher. During flipping, the flipping drive component needs to drive the linkage end to move to the other end of the arc-shaped slide groove. At this time, the elastic pusher resets and applies a pushing force to the linkage end, so that the linkage end moves smoothly. Similarly, when flipping to the bottom surface of the PCB board facing down, the linkage end compresses the elastic pusher at the other end of the arc-shaped slide groove. Due to the reset and pushing of the elastic pusher, the linkage end moves back and forth smoothly in the arc-shaped slide groove without jamming.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. During use, the PCB board is placed on the conveyor trough for feeding. The floating support conveyor mechanism generates an air film at the bottom of the trough to float and support the PCB board, effectively eliminating the effects of mechanical friction and vibration, preventing board slippage and displacement, improving feeding stability, and reducing direct contact friction during feeding to prevent scratches, indentations, or bending deformation. It is particularly suitable for thin boards, flexible boards, and large-size PCBs, protecting the integrity of the board surface. At the same time, a guide adjustment mechanism is set up. A vision inspection mechanism performs visual inspection on different PCBs to drive the guide adjustment mechanism to adjust and correct the feeding angle of the PCB board, correct the board entry posture, and ensure the smooth introduction of the PCB board. In addition, this application sets up a posture detection mechanism to detect the posture of the side of the PCB board. According to the different thicknesses of the PCB board, the pressure of the air film generated by the floating support conveyor mechanism is adjusted to maintain the balanced posture of PCB boards of different thicknesses during the feeding process. 2. When the PCB board is being fed into the feeding trough, the first detection camera inspects the front of the PCB board to obtain information such as the width of the PCB board, so as to adjust the distance between the first guide plate and the second guide plate. When the PCB board is conveyed to the underside of the flipping material picking structure, the flipping material picking structure picks it up and flips it 180° so that the bottom surface of the PCB board faces the second detection camera. The second detection camera inspects the bottom surface of the PCB board. If damage is found, an alarm is sounded and the defective product is removed. If the inspection is qualified, the PCB board is reset and flipped 180° so that the bottom surface of the PCB board is facing down and placed back on the feeding trough. Attached Figure Description

[0031] The following is in conjunction with the appendix Figures 1 to 5 This application will be described in further detail.

[0032] This application discloses a floating support conveyor feeding device, such as... Figure 1 The system includes a conveying platform 1 with a conveying trough 2, a floating support conveying mechanism 3 on the conveying platform 1, a guiding adjustment mechanism 4 in the conveying trough 2, a vision inspection mechanism 5 on the conveying platform 1, and an attitude detection mechanism 6. The floating support conveying mechanism 3 is used to generate an air film at the bottom of the conveying trough 2 to float and support the PCB board in the conveying trough 2. The guiding adjustment mechanism 4 is used to guide the PCB board in the conveying trough 2 and adjust the feeding angle of the PCB board. The vision inspection mechanism 5 is used to perform visual inspection on the PCB board in the conveying trough 2 to drive the guiding adjustment mechanism 4 to adjust and correct the feeding angle of the PCB board. The attitude detection mechanism 6 is used to perform attitude detection on the side of the PCB board in the conveying trough 2 to adjust the pressure of the air film generated by the floating support conveying mechanism 3.

[0033] In this application, the PCB board is placed on the conveyor trough for feeding. The floating support conveyor mechanism generates an air film at the bottom of the trough, which floats and supports the PCB board, effectively eliminating the effects of mechanical friction and vibration, preventing board slippage and displacement, and improving feeding stability. It also reduces direct contact friction during feeding, preventing scratches, indentations, or bending deformation. This is particularly suitable for thin boards, flexible boards, and large-size PCBs, protecting the integrity of the board surface. A guide adjustment mechanism is also included. A vision inspection mechanism visually inspects different PCBs to drive the guide adjustment mechanism to adjust and correct the feeding angle of the PCB board, correcting its insertion posture and ensuring smooth board introduction. Furthermore, this application includes a posture detection mechanism that detects the posture of the PCB board's sides. Based on the different thicknesses of the PCB board, the pressure of the air film generated by the floating support conveyor mechanism is adjusted to maintain the balanced posture of PCB boards of different thicknesses during feeding.

[0034] Furthermore, the floating support conveying mechanism 3 includes multiple air outlets 31 arranged in a matrix on the bottom of the conveying trough 2. Optionally, the floating support conveying mechanism 3 also includes an air outlet chamber located within the conveying platform 1 and connected to the air outlets 31. Airflow generated by the vacuum generator is ejected from the air outlet chamber through the air outlets 31 to form an air film that provides air buoyancy support for the PCB board on the bottom of the conveying trough 2. Optionally, the floating support conveying mechanism 3 also includes air outlet nozzles located within the conveying platform 1 and corresponding one-to-one with the air outlets 31. Airflow generated by the vacuum generator is ejected from the air outlet nozzles, which are inclined along the board conveying direction, thus providing air buoyancy support and conveying for the PCB board. This achieves pneumatic conveying, effectively eliminating the effects of mechanical friction and vibration, and preventing board slippage and displacement. Furthermore, it reduces direct contact friction during loading, preventing scratches, indentations, or bending deformation, making it particularly suitable for thin boards, flexible boards, and large-size PCBs. Furthermore, the floating support conveying mechanism 3 also includes an air outlet nozzle, and the attitude detection mechanism 6 includes laser rangefinders 61 disposed on both sides of the conveying platform 1. The air outlet nozzle is linked to the laser rangefinders 61 through a control and feedback unit. The laser rangefinders 61 are used to detect the thickness of the PCB board. By detecting the thickness and tilt angle of the PCB board, the air pressure of the air outlet nozzle is adjusted to maintain the balanced attitude of PCB boards of different thicknesses and materials during the loading process.

[0035] Furthermore, such as Figure 3As shown, the guiding adjustment mechanism 4 includes a first guide plate 41 disposed on the conveying trough 2 along the conveying direction, a second guide plate 42 disposed on the conveying trough 2 along the conveying direction and disposed opposite to the first guide plate 41, a first adjustment component 43 disposed between the conveying platform 1 and the first guide plate 41, and a second adjustment component 44 disposed between the conveying platform 1 and the second guide plate 42. The first adjustment component 43 is used to drive the first guide plate 41 to move closer to or away from the second guide plate 42, and the second adjustment component 44 is used to drive the second guide plate 42 to move closer to or away from the first guide plate 41.

[0036] This application can adjust the distance between the first guide plate and the second guide plate, as well as the position of the discharge port, according to PCB boards of different widths, so that the discharge port is aligned with the feeding groove, avoiding deviation of the entry angle or even jamming of the board.

[0037] Furthermore, the first adjustment component 43 includes a first guide post 431 disposed on the conveying platform 1 along the movement direction of the first guide plate 41, a first guide member 432 connected at one end to the first guide plate 41 and movably sleeved on the first guide post 431 at the other end, and a first adjustment drive member 433 disposed on the conveying platform 1 and connected at the drive end to the first guide plate 41. The first adjustment drive member may be a telescopic cylinder, which controls the reciprocating movement of the first guide plate by telescopic movement, and the first guide post and the first guide member are provided to slide in cooperation to make the movement of the first guide member stable.

[0038] Further, the second adjustment assembly 44 includes a second guide post 441 disposed on the conveying platform 1 along the movement direction of the second guide plate 42, a second guide member 442 connected at one end to the second guide plate 42 and movably sleeved on the second guide post 441 at the other end, and a second adjustment drive member 443 disposed on the conveying platform 1 and connected at its driving end to the second guide plate 42. Optionally, the second adjustment drive member may be a telescopic cylinder, which controls the reciprocating movement of the second guide plate by telescopic movement, and the second guide post and the second guide member are provided in sliding engagement to ensure stable movement of the second guide member.

[0039] Furthermore, such as Figure 2 As shown, the guide adjustment mechanism 4 also includes an adjustment mounting piece 45 disposed on the conveying platform 1 and one end extending into the conveying groove 2, a swing adjustment rod 46 with one end hinged to the end of the adjustment mounting piece 45 extending into the conveying groove 2, and a swing drive piece 47 disposed on the conveying platform 1 and the drive end connected to the swing adjustment rod 46. The swing drive piece 47 is used to drive the swing adjustment rod 46 to swing, so as to adjust the loading angle of the PCB board on the conveying groove 2.

[0040] Optionally, the swing drive is a telescopic cylinder. Based on the PCB board detected by the detection camera, the telescopic cylinder drives the swing adjustment rod to swing to adjust the PCB board's slot angle.

[0041] Furthermore, such as Figure 1 As shown, the system also includes a flipping and loading mechanism 7. The flipping and loading mechanism 7 includes a rotating roller 71 rotatably mounted on the conveying platform 1, a flipping drive component 72 for driving the rotating roller 71 to rotate, and loading support and limiting strips 73. Multiple loading support and limiting strips 73 are arranged circumferentially along the rotating roller 71, forming a loading groove 74 between adjacent loading support and limiting strips 73. The guide adjustment mechanism 4 guides the PCB board in the conveying groove 2 and adjusts the entry angle of the PCB board when it enters the loading groove 74. Optionally, the flipping drive component 72 is a rotating motor. The guide adjustment mechanism guides the PCB board in the conveying groove and adjusts the entry angle of the PCB board when it enters the loading groove, ensuring the PCB board enters the loading groove stably. The loading support and limiting strips provide support and limiting, and a fan dissipates heat and dries the PCB board during the flipping process.

[0042] Furthermore, the visual inspection mechanism 5 includes a first inspection mounting member 51 and a first inspection camera 52 disposed on the first inspection mounting member 51 and corresponding to the conveying groove 2. The visual inspection mechanism 5 also includes a second inspection mounting member 53 disposed in front of the first inspection mounting member 51 along the conveying direction and a second inspection camera 54 disposed on the second inspection mounting member 53 and corresponding to the conveying groove 2. A flipping material picking structure 81 is provided between the second inspection camera 54 and the conveying groove 2. The flipping material picking structure is used to pick up the PCB board on the conveying groove 2 and flip the PCB board 180° so that the bottom surface of the PCB board faces the second inspection camera 54.

[0043] When the PCB board is loaded into the feeding trough, the first detection camera detects the front of the PCB board to obtain information such as the width of the PCB board, so as to adjust the distance between the first guide plate and the second guide plate. When the PCB board is conveyed to the underside of the flipping material picking structure, the flipping material picking structure picks it up and flips it 180° so that the bottom surface of the PCB board faces the second detection camera. The second detection camera detects the bottom surface of the PCB board. If damage is found, an alarm is triggered in time to remove the defective product. If the inspection is qualified, the PCB board is reset and flipped 180° so that the bottom surface of the PCB board is facing down and placed back on the feeding trough.

[0044] Furthermore, such as Figure 4-5As shown, the flipping material handling structure 81 includes a flipping mounting frame 811, a flipping shaft 812 rotatably mounted on the flipping mounting frame 811, an adsorption member 813 mounted on the flipping shaft 812, and a flipping drive mechanism 814 for driving the flipping shaft 812 to flip. The flipping drive mechanism 814 includes a drive mounting base 8141 mounted on the flipping mounting frame 811, a drive slider 8142 movably mounted on the drive mounting base 8141, a flipping linkage member 8143, an elastic push member 8144, and a flipping drive member 8145. The drive slider 8142 is provided with an arc-shaped groove 8142a. One end of the flip linkage 8143 is eccentrically connected to the flip shaft 812, and the other end is provided with a linkage end 8143a. The linkage end 8143a extends into the arc-shaped groove 8142a and can move along the arc-shaped groove 8142a. Two elastic pushers 8144 are provided on the drive slider 8142 and extend into both ends of the arc-shaped groove 8142a respectively. The linkage end 8143a can move along the arc-shaped groove 8142a to both ends of the arc-shaped groove 8142a and compress the elastic pushers 8144. The flip drive 8145 is provided on the flip mounting bracket 811 and is used to drive the drive slider 8142 to move. In addition, the flipping material handling structure 81 also includes a lifting track 815, on which a slider is provided that moves in the vertical direction. The flipping mounting frame 811 is connected to the slider and is driven by a telescopic cylinder or a motor to move in the vertical direction.

[0045] In use, the flipping drive unit drives the drive slider to move on the drive mounting base. The movement of the drive slider corresponds to the movement of the arc-shaped slide groove, which in turn pushes the linkage end extending into the arc-shaped slide groove to move along the groove, thereby rotating the flipping linkage unit and achieving the flipping axis flipping. When the bottom surface of the PCB board faces the second detection camera, the linkage end is located at one end of the arc-shaped slide groove and compresses the elastic pusher. During flipping, the flipping drive unit needs to drive the linkage end to the other end of the arc-shaped slide groove. At this time, the elastic pusher resets and applies a pushing force to the linkage end, ensuring smooth movement of the linkage end. Similarly, when flipping to the bottom surface of the PCB board facing down, the linkage end compresses the elastic pusher at the other end of the arc-shaped slide groove. Due to the reset and pushing of the elastic pusher, the linkage end moves smoothly back and forth in the arc-shaped slide groove without jamming. The adsorption unit is connected to a vacuum machine, adsorbing the PCB board through vacuum to avoid damaging the material. Multiple adsorption units can be arranged along the flipping axis according to the size of the material to be adsorbed. Specifically, the flipping angle of the flipping shaft is in the range of 0-180°, and the arc-shaped groove is a semi-circular arc-shaped groove.

[0046] Furthermore, in order to make the reciprocating movement of the linkage end 8143a in the arc-shaped slide groove 8142a smoother and more stable, a rolling bearing 9 is sleeved on the linkage end 8143a.

[0047] The implementation principle of a floating support conveyor feeding device according to an embodiment of this application is as follows: In use, the PCB board is placed on the conveyor trough for feeding. Airflow generated by a vacuum generator is ejected from the air outlet nozzle, which is tilted along the board conveying direction. This provides air-floating support and conveying for the PCB board, achieving pneumatic conveying and effectively eliminating the effects of mechanical friction and vibration, preventing board slippage and displacement. It also reduces direct contact friction during feeding, preventing scratches, indentations, or bending deformation, making it particularly suitable for thin boards, flexible boards, and large-size PCBs, protecting the integrity of the board surface. A guide adjustment mechanism is also included, using a vision inspection mechanism to visually inspect different PCBs, driving the guide adjustment mechanism to adjust and correct the feeding angle of the PCB board, correcting the board's entry posture, and ensuring smooth board introduction. Furthermore, this application includes a posture detection mechanism to detect the posture of the PCB board's sides. Based on the different thicknesses of the PCB board, the air film pressure generated by the floating support conveyor mechanism is adjusted to maintain the balanced posture of PCB boards of different thicknesses during feeding.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
