Description

Technical Field

[0001] This invention relates to the field of PCB processing equipment technology, and in particular to a slanted vertical PCB winding machine. Background Technology

[0002] In PCB (Printed Circuit Board) manufacturing, the transfer of boards between different processing equipment typically uses a rack for temporary storage. The rack has a backrest and at least two identical, angled support plates. These two support plates are parallel to each other and distributed laterally. The boards are angled against the backrest, giving them an inclined position. When transferring boards one by one from the conveyor rail to the rack, a board reel is used. Current board reel machines generally use a clamp-like mechanism to hold the lower end of the board and drive it to rotate, causing the board to lean against the rack at an angle. During this process, the clamped area of ​​the board is prone to deformation and even breakage. Summary of the Invention

[0028] Reference Figure 1 and Figure 2 This invention discloses a slanted vertical plate collecting machine, including a frame 100, a flipping mechanism 200, a plate receiving device 400, and a suction device 300. The frame 100 is equipped with a first conveying mechanism 110 and a second conveying mechanism 120 distributed front to back. The first conveying mechanism 110 and the second conveying mechanism 120 are respectively used to convey plates and a material rack 700. (Refer to...) Figure 1 , Figure 3 and Figure 5 The flipping mechanism 200 includes a rotary drive mechanism 210 connected to the frame 100, a swing arm 220 located at the output end of the rotary drive mechanism 210, and a support plate 230 located on the free end of the swing arm 220. One end of the support plate 230 is provided with a limiting part 231 for the lower end of the plate to extend into. The rotary drive mechanism 210 drives the swing arm 220 to swing, so that the support plate 230 and the limiting part 231 drive the plate on the first conveying mechanism 110 to rotate. (Refer to...) Figure 1 , Figure 2 and Figure 5The receiving plate device 400 includes a lifting plate 410 that is movably mounted on the frame 100. The lifting plate 410 is located behind the flipping mechanism 200. A support plate 412 is provided on the front side of the lifting plate 410. The upper surface of the support plate 412 is parallel to the upper surface of the support plate of the material rack 700. The support plate 412 is used to lift the lower end of the plate on the limiting part 231 and place the plate on the support plate. (Refer to...) Figure 1 , Figure 2 , Figure 4 and Figure 5 The suction plate device 300 includes a first linear drive mechanism 330 disposed on the frame 100 and an adsorption component 340 disposed on the output end of the first linear drive mechanism 330. The adsorption component 340 is used to adsorb the lower end of the plate on the tray 412. The first linear drive mechanism 330 drives the adsorption component 340 to move along a trajectory parallel to the inclined surface of the support plate so that the plate is stacked on the material rack 700.

[0029] See Figure 5 In the initial state, the material rack 700 is at the front end of the second conveying mechanism 120, the lifting plate 410 is at a high position, the lifting plate 410 passes through the gap between the two support plates of the material rack 700 and is in front of the backrest, and the pallet 412 is higher than the support plate, the adsorption component 340 is in front of the pallet 412, and the swing arm 220 and the backrest 230 are next to the pallet 412 and will not interfere with the pallet 412 or the adsorption component 340. When the plate collecting machine is working, the rotary drive mechanism 210 drives the swing arm 220 to swing, so that the back plate 230 and the first conveying mechanism 110 are parallel to each other. The plate is conveyed to the back plate 230 through the first conveying mechanism 110 and the rear end of the plate abuts against the limiting part 231. Then the rotary drive mechanism 210 drives the swing arm 220 to swing in the opposite direction. The back plate 230 will swing with the plate. The plate will change from a flat state to a forward tilting state, an upright state, and a backward tilting state in sequence. During this process, the rear end of the plate becomes the lower end. The lower end of the plate will abut against the support plate 412. The first linear drive mechanism 330 drives the adsorption component 340 to move backward, so that the adsorption component 340 adsorbs the lower end of the plate. The swing arm 220 continues to swing in the opposite direction. The height of the limiting part 231 is lower than the height of the support plate 412. The lower end of the plate will disengage from the limiting part 231 and completely abut against the support plate 412. From this point on, the plate is transferred from the flipping mechanism 200 to the receiving device 400 and the suction device 300. Immediately afterwards, the lifting plate 410 descends, and the first linear drive mechanism 330 drives the adsorption component 340 to continue moving backward, so that the lower end of the plate falls on the support plate, completing the plate collection work.

[0030] See Figure 5During the continuous transfer of boards from the receiving machine to the material rack 700, the relative positions of the suction device 300 and the flipping mechanism 200 remain unchanged. The boards on the material rack 700 gradually accumulate forward. In order to smoothly transfer the boards from the first conveying mechanism 110 to the material rack 700, the material rack 700 needs to move backward, so that the boards on the material rack 700 are away from the suction device 300 and the flipping mechanism 200. The second conveying mechanism 120 gradually drives the material rack 700 to move backward, so that the receiving device 400 and the suction device 300 can place each board in the area above the support plate, avoiding the boards placed on the support plate first from obstructing or blocking the boards that need to be placed on the support plate.

[0031] During the board collection process, the board collecting machine does not require clamping or holding the board. The lifting plate 410, the pallet 412, and the adsorption component 340 act as a transfer mechanism between the backing plate 230 and the support plate, gently placing the board. The backing plate 230, the limiting part 231, the lifting plate 410, the pallet 412, and the adsorption component 340, which are in contact with the board, can all prevent the board from deforming, thus improving the safety of board transfer.

[0032] The surfaces of the backing plate 230 and the limiting part 231 are both covered with an elastic layer to prevent the material from colliding hard with the backing plate 230 and the limiting part 231, thus preventing the material from being damaged. One end of the backing plate 230 is hook-shaped, and the main body of the backing plate 230 and the hook form the limiting part 231, which has a groove structure.

[0033] The adsorption component 340 is a suction nozzle, and there are multiple suction nozzles. The suction plate device 300 also includes a negative pressure device, which is connected to the suction nozzle through an air tube.

[0034] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 In some embodiments, the receiving plate device 400 includes a connecting plate 420 connected to the lower end of the frame 100. The connecting plate 420 is provided with a second linear drive mechanism 421. The output end of the second linear drive mechanism 421 is connected to the lower end of the lifting plate 410. The second linear drive mechanism 421 drives the lifting plate 410 to rise and fall, so that the lifting plate 410 and the support plate 412 pass through the gap between the two support plates.

[0035] The second linear drive mechanism 421 is one of a second cylinder, a lead screw pair, and an electric actuator.

[0036] Reference Figure 5 and Figure 6In some embodiments, the lower end of the frame 100 is provided with a crossbar 140, the length direction of the crossbar 140 is left and right. The upper end of the connecting plate 420 is connected to the crossbar 140 by a clamp 422. Loosening the clamp 422 allows the connecting plate 420 to swing around the crossbar 140, thereby adjusting the forward or backward tilt angle of the connecting plate 420 and the second linear drive mechanism 421, thereby realizing the adjustment of the forward or backward tilt angle of the lifting plate 410. The forward or backward tilt angle of the lifting plate 410 is related to whether the upper end of the plate abuts against the upper end of the lifting plate 410 after the lower end of the plate abuts against the support plate 412, and whether the tilt angle of the plate is the same as the tilt angle of the backrest after the upper and lower ends of the plate abut against the upper end of the lifting plate 410 and the support plate 412 respectively. When the lifting plate 410 is tilted forward or backward at a suitable angle, the lower end of the plate rests against the support plate 412, while the upper end of the plate rests against the upper end of the lifting plate 410. At this time, the lifting plate 410 and the support plate 412 work together on the plate, and the plate is in the most stable state.

[0037] The clamp 422 includes two connecting blocks connected together by fasteners. A through hole is formed between the two connecting blocks for the crossbar 140 to pass through. One of the connecting blocks is fixedly connected to the upper end of the connecting plate 420. When the fasteners are tightened, the two connecting blocks move closer to each other to firmly clamp the crossbar 140, thereby fixing the connecting plate 420 to the crossbar 140.

[0038] Reference Figure 6 In some embodiments, the lifting plate 410 and the support plate 412 are provided with clearance openings in the areas corresponding to the swing arm 220 and the back plate 230. When the rotary drive mechanism 210 drives the swing arm 220 to swing in the opposite direction, the limiting part 231 on the back plate 230 passes through the clearance opening and swings to the lower surface of the support plate 412, thereby transferring the lower end of the plate from the limiting part 231 to the support plate 412.

[0039] Reference Figure 5 and Figure 6 The upper end of the lifting plate 410 is provided with a rotating wheel 411. The wheel surface of the rotating wheel 411 protrudes from the upper end surface and the front side surface of the lifting plate 410. The plate rests against the rotating wheel 411. When the lifting plate 410 descends, the rotating wheel 411 rolls over the side of the plate, which can prevent the side of the plate from being scratched.

[0040] See Figure 1In some embodiments, the first conveying mechanism 110 is a roller conveyor, and the position of the first conveying mechanism 110 is higher than that of the second conveying mechanism 120. The input end of the second conveying mechanism 120 is correspondingly set with the output end of the first conveying mechanism 110, so that when the swing arm 220 and the backing plate 230 swing, the free end of the swing arm 220 and the limiting part 231 on the backing plate 230 are lower than the support plate, or the free end of the swing arm 220 and the backing plate 230 are flush with the conveying surface of the first conveying mechanism 110.

[0041] In some embodiments, the conveying directions of the second conveying mechanism 120 and the first conveying mechanism 110 can both be in the front-to-back direction. In this case, the front end of the second conveying mechanism 120 is correspondingly set with the rear end of the first conveying mechanism 110. The conveying roller of the first conveying mechanism 110 has a groove in the area corresponding to the backing plate 230. When the backing plate 230 swings, the backing plate 230 can enter the groove, so that the backing plate 230 is lower than the conveying surface of the conveying roller and the backing plate 230 will not interfere with the conveying roller. The groove plays the role of avoiding and temporarily storing the backing plate 230.

[0042] In this embodiment, the conveying roller of the first conveying mechanism 110 includes a roller shaft and a plurality of rollers disposed on the roller shaft. There is a gap between two adjacent rollers on the same roller shaft. When the back plate 230 swings, the back plate 230 can enter the gap, so that the back plate 230 is lower than the conveying surface of the conveying roller and the back plate 230 will not interfere with the conveying roller. The gap plays the role of avoiding and temporarily storing the back plate 230.

[0043] In another embodiment, the conveying direction of the second conveying mechanism 120 is the front-to-back direction, and the conveying direction of the first conveying mechanism 110 is the left-to-right direction. In this case, the front end of the second conveying mechanism 120 is correspondingly positioned with the left or right end of the first conveying mechanism 110. There is a gap between two adjacent conveying rollers on the first conveying mechanism 110, and the abutment plate 230 can enter this gap, which also ensures that the abutment plate 230 is lower than the conveying surface of the conveying roller and does not interfere with the conveying roller. Similarly, the conveying direction of the second conveying mechanism 120 can be the left-to-right direction, and the conveying direction of the first conveying mechanism 110 can be the front-to-back direction.

[0044] When the second conveying mechanism 120 is a roller conveyor, the suction plate device 300 and the flipping plate mechanism 200 are located between two adjacent conveying rollers at the front end of the roller conveyor. When the second conveying mechanism 120 consists of two parallel belt conveyors, the suction plate device 300 and the flipping plate mechanism 200 are located at the front end between the two belt conveyors. It should be understood that the two support plates of the material rack 700 are L-shaped plates, connected together with a gap between them, allowing the lifting plate 410, pallet 412, swing arm 220, and backing plate 230 to enter this gap.

[0045] See Figure 2 and Figure 4The suction plate device 300 also includes an elastic element 310 and a lifting frame 320. The lifting frame 320 is movably mounted on the frame 100. The elastic element 310 can drive the lifting frame 320 to abut against the support plate of the material rack 700. The first linear drive mechanism 330 drives the adsorption component 340 to move along a trajectory parallel to the inclined surface of the support plate. The adsorption component 340 is used to adsorb the lower end of the plate and carry the plate backward.

[0046] When the material rack 700 moves, the vertical distance between the first linear drive mechanism 330, the adsorption component 340 and the inclined surface or upper surface of the support plate remains unchanged, so that the moving trajectory of the adsorption component 340 is always parallel to the inclined surface of the support plate, and finally the adsorption component 340 can press the material against the backrest.

[0047] See Figure 4 The suction plate device 300 also includes a lifting drive mechanism 350 disposed on the frame 100. The output end of the lifting drive mechanism 350 is connected to the lifting frame 320. The first linear drive mechanism 330 is disposed on the frame 100 through the lifting frame 320. The lifting drive mechanism 350 is used to drive the lifting frame 320, the first linear drive mechanism 330 and the suction component 340 to lift.

[0048] The lifting drive mechanism 350 drives the lifting frame 320 to rise, preventing the lifting frame 320, the first linear drive mechanism 330, and the adsorption component 340 from obstructing the movement of the material rack 700. Initially, the lifting drive mechanism 350 drives the lifting frame 320 to a high position, at which point the elastic element 310 undergoes significant deformation. The second conveying mechanism 120 drives the material rack 700 forward, placing the support plate below the adsorption component 340 and the flipping mechanism 200. Then, the lifting drive mechanism 350 drives the lifting frame 320 to descend, or the lifting drive mechanism 350 ceases to act on the lifting frame 320. Under the influence of gravity and the elastic element 310, the lifting frame 320 rests against the support plate.

[0049] The lifting drive mechanism 350 is the first cylinder. The piston rod of the first cylinder is set upward and connected to the lifting frame 320. After the first cylinder is cut off, that is, after the first cylinder is not controlled, the piston rod can descend freely.

[0050] See Figure 2 and Figure 4In some embodiments, a mounting plate 360 ​​is hinged to the lifting frame 320, and a first linear drive mechanism 330 is mounted on the lifting frame 320 via the mounting plate 360. A floating joint 370 is connected between the lifting frame 320 and the mounting plate 360 ​​to adjust the tilt angle of the mounting plate 360, thereby adjusting the tilt angle of the movement trajectory of the first linear drive mechanism 330 and the adsorption component 340, ensuring that the tilt angle of the movement trajectory of the first linear drive mechanism 330 and the adsorption component 340 is consistent with the tilt angle of the upper surface of the support plate, so that the suction plate device 300 can be applied to support plates with different tilt angles on the upper surface.

[0051] See Figure 4 In some embodiments, the system also includes a cooperating guide rod 500 and a guide sleeve 600, one of which is connected to the lifting frame 320 and the other is connected to the frame 100. The guide rod 500 and the guide sleeve 600 serve to guide the lifting frame 320 in its vertical movement.

[0052] In some embodiments, the elastic element 310 is sleeved on the guide rod 500, and the two ends of the elastic element 310 abut or connect with the frame 100 and the guide rod 500 / lifting frame 320 respectively, so that when the lifting frame 320 rises, the elastic element 310 undergoes energy storage deformation.

[0053] See Figure 5 It is understood that the frame 100 is provided with a horizontal plate 130, the lower end of the lifting frame 320 is connected to the guide rod 500, the guide rod 500 is set vertically, the guide sleeve 600 is connected to the horizontal plate 130, the lower end of the guide rod 500 passes through the guide sleeve 600 and extends to the lower part of the horizontal plate 130, and the lower end of the guide rod 500 is detachably connected to a baffle by fasteners. An elastic element 310 is sleeved on the guide rod 500, and the two ends of the elastic element 310 abut against the lower surface of the horizontal plate 130 and the baffle, respectively. The elastic element 310 is a spring.

[0054] See Figure 4 In some embodiments, the lifting frame 320 is provided with guide wheels 321. The lifting frame 320 abuts against the support plate through the guide wheels 321. When the material rack 700 moves, the guide wheels 321 can reduce the frictional resistance between the lifting frame 320 and the support plate, thus avoiding greater resistance to the movement of the material rack 700.

[0055] See Figure 3In some embodiments, the flip-plate mechanism 200 further includes a support frame 240 and a rotating shaft 250 rotatably mounted on the support frame 240. A rotary drive mechanism 210 is connected to the support frame 240 and driven by the rotating shaft 250. There are two swing arms 220 and two support plates 230. The swing arms 220 are L-shaped and include mutually perpendicular connecting ends and free ends. The two connecting ends are fixedly connected to both ends of the rotating shaft 250. The two support plates 230 are respectively located on the two free ends and are parallel to the connecting ends. The rotary drive mechanism 210 drives the rotating shaft 250 to rotate, which in turn drives the two swing arms 220 and the two support plates 230 to rotate, thus enabling the swing arms 220 and the support plates 230 to swing. The two support plates 230 respectively support the left and right ends of the plate, ensuring that the left and right ends of the plate are balanced.

[0056] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0057] Of course, the present invention is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
