Description

Technical Field

[0001] The present invention belongs to the technical field of PCB production, and in particular relates to an automatic width-adjusting and board-feeding device for a connecting table used in PCB production. Background Art

[0002] With the rapid development of the domestic automatic special-shaped plug-in machine industry, there is an urgent need to strengthen the research on the basic theory of automatic special-shaped plug-in machines to adapt to the continuous development of production practice and provide theoretical guidance for production practice.

[0003] During the production process, PCB boards need to be transported through docking stations. Existing docking stations generally adjust the track width according to the size of the PCB boards. To ensure smooth passage of the boards without shaking, the track width is usually 1-2mm wider than the board width. Due to the poor quality of the PCB boards in the docking state and the track width being wider than the board width, the PCB boards may rotate or shift to the side after being moved to the docking station, which can easily cause friction between the PCB boards and even jamming, making it impossible to accurately position the PCB boards and reducing conveying efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a PCB production docking station automatic width adjustment board feeding device, aiming to solve the technical problems in the prior art that the accuracy of PCB board position cannot be guaranteed and the conveying efficiency is reduced.

[0007] Further technical solution: A track plate located inside the conveyor belt is fixedly mounted on the base plate, and a surface of the track plate away from the base is in sliding contact with a horizontal section of the conveyor belt.

[0008] Further technical solution: A connecting hexagonal shaft is rotatably installed on the mounting plate, and the connecting hexagonal shaft is parallel to the cross bar. A driving wheel rotatably connected to the transmission belt is rotatably installed on the base plate, and the driving wheel is slidingly connected to the connecting hexagonal shaft. The first rotating power component is rotatably connected to the connecting hexagonal shaft through a synchronous belt and a synchronous pulley.

[0009] Further technical solution: The surfaces of the two groups of substrates close to each other are fixedly mounted with brackets, the movable plate is slidably mounted on the bracket, and a second servo module for driving the movable plate to move is provided on the bracket.

[0010] Further technical solution: A blowing chamber is fixedly installed on the track plate, and a plurality of groups of blowing holes are opened on the surface of the blowing chamber away from the base. The blowing chamber is connected to the fan fixedly installed on the mounting plate.

[0011] Further technical solution: A first baffle and a second baffle are slidingly installed in the blowing chamber. The first baffle and the second baffle are distributed along the length direction of the blowing chamber and pass through the side wall of the blowing chamber. The first baffle and the second baffle are located in the part of the blowing chamber that blocks the blowing hole. The first baffle is connected to the second baffle, and a third servo module is provided on the blowing chamber to drive the first baffle to move.

[0012] Further technical solution: A connecting plate is fixedly installed on the first baffle, the connecting plate passes through the second baffle and is slidably connected to the second baffle, and a fixing screw is threadedly installed on one end of the second baffle away from the first baffle.

[0013] Further technical solution: A support plate is fixedly installed on the rotating plate, a lifting plate is slidably installed on the support plate, a pressure plate is fixedly installed near one end of the lifting plate near the base, a fixed plate is fixedly installed on the support plate, an electromagnet is fixedly installed on the fixed plate, and the electromagnet is used in conjunction with a permanent magnet fixedly installed on the lifting plate.

[0014] Further technical solution: a limit plate is slidably installed on the fixed plate, an elastic part is fixedly installed on the limit plate, one end of the elastic part away from the limit plate is fixedly connected to the lifting plate, and an adjusting screw is rotatably installed on the support plate to drive the limit plate to move.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The moving plate moves synchronously with the PCB, and then the second telescopic member drives the rotating plate, limit column and distance sensor to move, so as to detect the position of the PCB and adjust the PCB according to the detection results. The movement range of the PCB during the adjustment process is reduced, ensuring that the PCB is in the correct position, avoiding edge collision or board jamming caused by the tilt of the PCB edge, and improving the conveying efficiency of the equipment.

[0017] 2. When adjusting the position of the PCB board, the fan is turned on and delivers air into the blowing chamber. The air is blown upward to the PCB board through the blowing holes 5 between the first baffle and the second baffle. The upward flowing air exerts an upward thrust on the PCB board, thereby reducing the friction between the PCB board and the conveyor belt. After the limit column contacts the side of the PCB board, a small thrust is exerted to cause the PCB board to deflect and rotate, so that the PCB board can deflect and rotate more smoothly, avoiding the jumping of the PCB board during the initial deflection and rotation due to a large thrust, ensuring the stable deflection and rotation of the PCB board, thereby ensuring the accuracy of the PCB board position adjustment and further improving the conveying efficiency of the PCB board. During the adjustment process, the first baffle and the second baffle move synchronously with the PCB board, so that the air is always blown upward below the PCB board, ensuring the stability of the force of the air on the PCB board and further improving the accuracy of the PCB board position adjustment.

[0018] 3. When adjusting the position of the PCB board, when the distances detected by the two sets of distance measuring sensors are the same, the electromagnet is energized and repels the permanent magnet. At this time, the lifting plate moves downward to compress the elastic part and the pressure plate presses the PCB board onto the conveyor belt. At the same time, the fan stops supplying air. When it is detected that the position of the PCB board is accurately adjusted, the pressure plate immediately presses the PCB board down and fixes it, preventing the PCB board from further deflecting and moving, and preventing the PCB board from being over-adjusted due to the influence of air, thereby further improving the accuracy of the PCB board adjustment position.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0028] like Figures 1-6 As shown, a PCB production docking station automatic width adjustment and feeding device provided by the present invention includes a base 1, a mounting plate 3 is provided on the base 1, and a first telescopic member 2 that drives the mounting plate 3 to move up and down is fixedly installed on the base 1, a crossbar 7 is fixedly installed on the mounting plate 3, two groups of base plates 8 are slidably installed on the crossbar 7, and a first servo module 9 that drives the two groups of base plates 8 to move synchronously in opposite directions is provided on the mounting plate 3, and the surfaces of the two groups of base plates 8 that are close to each other are provided with a conveyor belt 11 through a pulley, and a track plate 12 located in the conveyor belt 11 is fixedly installed on the base plate 8. The surface of the track plate 12 away from the base 1 is in sliding contact with the horizontal section of the conveyor belt 11. The first rotating power member 15 that drives the conveyor belt 11 to rotate is fixedly installed on the mounting plate 3. The connecting hexagonal shaft 10 is rotatably installed on the mounting plate 3. The connecting hexagonal shaft 10 is parallel to the cross bar 7. A driving wheel that is rotatably connected to the conveyor belt 11 is rotatably installed on the base plate 8. The driving wheel is slidably connected to the connecting hexagonal shaft 10. The first rotating power member 15 is rotatably connected to the connecting hexagonal shaft 10 through a synchronous belt and a synchronous pulley. A photoelectric sensor 16 is fixedly installed at both ends of one group of base plates 8.

[0029] The surfaces of the two groups of substrates 8 that are close to each other are both provided with a movable plate 19 that moves along the conveying direction of the PCB board. The surfaces of the two groups of substrates 8 that are close to each other are both fixedly installed with a bracket 17. The movable plate 19 is slidably installed on the bracket 17. The bracket 17 is provided with a second servo module 18 that drives the movable plate 19 to move. The movable plate 19 is provided with a connecting frame 21 and a second telescopic member 20 that drives the connecting frame 21 to move is fixedly installed on the movable plate 19. A rotating plate 22 is rotatably installed on the connecting frame 21 and a second rotating power member 23 that drives the rotating plate 22 to rotate is fixedly installed on the connecting frame 21. The side of the rotating plate 22 is fixedly installed with spaced limit columns 24 and ranging sensors 25. Two groups of limit columns 24 and ranging sensors 25 are provided.

[0030] In actual application, the present embodiment drives the two groups of substrates 8 to move synchronously in opposite directions according to the width of the PCB board being conveyed through the first servo module 9, so that the distance between the two groups of substrates 8 is 1-2 mm larger than the width of the PCB board. The first rotating power member 15 drives the connecting hexagonal shaft 10 to rotate through the synchronous belt and synchronous pulley, and then the connecting hexagonal shaft 10 drives the conveyor belt 11 to rotate through the driving wheel. The track plate 12 ensures that the PCB board moves in the horizontal direction. After the PCB board moves onto the conveyor belt 11, the position of the PCB board is detected by the photoelectric sensor 16. In the initial state, one group of rotating plates 22 is in a horizontal state, and the other group of rotating plates 22 is in a vertical state. When the PCB board moves, the first rotating power member 15 drives the connecting hexagonal shaft 10 to rotate through the synchronous belt and synchronous pulley, and then the connecting hexagonal shaft 10 drives the conveyor belt 11 to rotate through the driving wheel. The track plate 12 ensures that the PCB board moves in the horizontal direction. After the PCB board moves to the conveyor belt 11, the photoelectric sensor 16 detects the position of the PCB board. In the initial state, one group of rotating plates 22 is in a horizontal state, and the other group of rotating plates 22 is in a vertical state. When the rotating plate 22 moves to the set position close to the vertical state, the second servo module 18 drives the movable plate 19 to move, and the moving speed of the movable plate 19 is the same as the moving speed of the PCB board. At the same time, the two sets of distance measuring sensors 25 detect the distance between the rotating plate 22 and the side of the PCB board. If the distances detected by the two sets of distance measuring sensors 25 are the same, it means that the placement position of the PCB board has not shifted or rotated, and no adjustment is required. At this time, the PCB board is kept conveyed, and the second rotating power member 23 drives the rotating plate 22 to rotate until the height of the lower end of the rotating plate 22 is higher than the height of the upper surface of the PCB board, and then the movable plate 19 is reset. The rotating plate 22 passes over the PCB board and rotates to the vertical state again.

[0031] If the distances detected by the two sets of distance measuring sensors 25 are different, it means that the placement position of the PCB board has shifted and rotated. At this time, the second telescopic member 20 drives the connecting frame 21 to move toward the direction close to the PCB board. One set of limiting posts 24 first contacts the side of the PCB board. Then, this set of limiting posts 24 pushes the PCB board to shift and rotate. During this process, the distance measuring sensor 25 always keeps detecting. When the distances detected by the two sets of distance measuring sensors 25 are the same, the second telescopic member 20 stops extending. At this time, the placement position of the PCB board is adjusted. After the adjustment is completed, the second telescopic member 20 shrinks to its original length, so that the limiting posts 24 are separated from the PCB board. When the second telescopic member 20 shrinks, the rotating plate 22 rotates to a horizontal state. Then, the second servo module 18 drives the moving plate 19 to reset. During this process, if the other set of PCB boards Move it onto the conveyor belt 11, and repeat the above steps to detect and adjust through another set of rotating plates 22. The PCB board on the conveyor belt 11 is detected and adjusted in turn through the two sets of rotating plates 22 to achieve continuous operation of the equipment. The first telescopic member 2 drives the mounting plate 3 to rise or fall so that the conveyor belt 11 is at a set height, and then connects different equipment. The movable plate 19 moves synchronously with the PCB board, and then the second telescopic member 20 drives the rotating plate 22, the limit column 24 and the distance sensor 25 to move, so as to detect the position of the PCB board and adjust the PCB board according to the detection result, thereby reducing the movement amplitude of the PCB board during the adjustment process, ensuring that the PCB board is in the correct position, avoiding edge collision or board jamming caused by the tilt of the PCB board edge, and improving the conveying efficiency of the equipment.

[0032] In an example of this embodiment, the first rotating power member 15 and the second rotating power member 23 are respectively the first and second motors, and of course they can also be other components that can output rotational power, such as hydraulic motors. The first motor drives the conveyor belt 11 to rotate to realize the transportation of the PCB board, and the second motor drives the rotating plate 22 to rotate. The first telescopic member 2 and the second telescopic member 20 are respectively the first and second electric telescopic rods, and of course they can also be other components that can actively change the length, such as hydraulic cylinders. The first electric telescopic rod drives the mounting plate 3 to move up and down, and the second electric telescopic rod drives the connecting frame 21 to move.

[0033] like Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 As shown, an automatic width adjustment and board feeding device for a docking station for PCB production provided by the present invention, a blowing chamber 4 is fixedly installed on the track plate 12, and a plurality of groups of spaced-apart blowing holes 5 are provided on the surface of the blowing chamber 4 away from the base 1, and the blowing chamber 4 is connected to a fan 35 fixedly installed on the mounting plate 3.

[0034] Specifically, a first baffle 13 and a second baffle 14 are slidingly installed in the blowing chamber 4. The first baffle 13 and the second baffle 14 are distributed along the length direction of the blowing chamber 4 and pass through the side wall of the blowing chamber 4. The first baffle 13 and the second baffle 14 are located in the blowing chamber 4 to partially block the blowing hole 5. The first baffle 13 is connected to the second baffle 14, and a third servo module 36 is provided on the blowing chamber 4 to drive the first baffle 13 to move.

[0035] Specifically, a connecting plate 6 is fixedly mounted on the first baffle 13 , and the connecting plate 6 passes through the second baffle 14 and is slidably connected to the second baffle 14 . A fixing screw is threadedly mounted on one end of the second baffle 14 away from the first baffle 13 .

[0036] When the PCB board on the conveyor belt 11 moves to the set position close to the rotating plate 22 in the vertical state, the PCB board is located between the first baffle 13 and the second baffle 14. The air in the blowing chamber 4 can be blown upward to the PCB board through the blowing holes 5 between the first baffle 13 and the second baffle 14. The first baffle 13 and the second baffle 14 are driven by the third servo module 36 to move synchronously with the PCB board. The first baffle 13 and the second baffle 14 on both sides move synchronously with the PCB board. If the distances detected by the two sets of distance measuring sensors 25 are the same, the position of the PCB board does not need to be adjusted. At this time, the third servo module 36 drives the first baffle 13 to reset. If the distances detected by the two sets of distance measuring sensors 25 are different, the fan 35 is turned on and transports air into the blowing chamber 4. The air is blown upward to the PCB board through the blowing holes 5 between the first baffle 13 and the second baffle 14. The upward flowing air exerts an upward thrust on the PCB board, thereby reducing the friction between the PCB board and the conveyor belt 11. After the subsequent limiting column 24 contacts the side of the PCB board, a small thrust is exerted to make the PCB board offset and rotate, so that the PCB board can offset and rotate more smoothly, avoiding the jumping of the PCB board during the initial offset rotation caused by a large thrust, ensuring that the PCB board can offset and rotate stably, thereby ensuring the accuracy of the PCB board position adjustment, and further improving the conveying efficiency of the PCB board. During the adjustment process, the first baffle 13 and the second baffle 14 move synchronously with the PCB board, so that the air always keeps blowing upward under the PCB board, ensuring the stability of the force of the air on the PCB board, and further improving the accuracy of the PCB board position adjustment. After the PCB board position adjustment is completed, the fan 35 stops running and the first baffle 13 is reset.

[0037] like Figure 1-Figure 3 、 Figure 6As shown, an automatic width adjustment and board feeding device for a connecting table for PCB production provided by the present invention is provided. A support plate 26 is fixedly installed on the rotating plate 22, and a lifting plate 27 is slidably installed on the support plate 26. A pressure plate 28 is fixedly installed on the lifting plate 27 near one end of the base 1, and a fixed plate 29 is fixedly installed on the support plate 26. An electromagnet 30 is fixedly installed on the fixed plate 29. The electromagnet 30 is used in conjunction with a permanent magnet 31 fixedly installed on the lifting plate 27.

[0038] Specifically, a limit plate 33 is slidably mounted on the fixed plate 29, an elastic member 34 is fixedly mounted on the limit plate 33, and one end of the elastic member 34 away from the limit plate 33 is fixedly connected to the lifting plate 27, and an adjusting screw 32 is rotatably mounted on the support plate 26 to drive the limit plate 33 to move.

[0039] In actual application of this embodiment, in the initial state, the electromagnet 30 is powered off, and the limit plate 33 is moved by adjusting the screw 32 according to the thickness of the PCB board, so that the lower surface of the pressing plate 28 is close to the upper surface of the PCB board in the initial state. When the rotating plate 22 needs to be rotated to the horizontal state, the electromagnet 30 is powered on and attracts the permanent magnet 31 to move the pressing plate 28 upward away from the PCB board. When adjusting the position of the PCB board, when the distances detected by the two sets of distance measuring sensors 25 are the same, the electromagnet 30 is powered on and repels the permanent magnet 31. At this time, the lifting plate 27 moves downward to compress the elastic member 34 and cause the pressing plate 28 to press the PCB board. Plate B presses on the conveyor belt 11 and is cushioned by the elastic member 34, reducing the impact on the PCB. At the same time, the fan 35 stops delivering air. When it is detected that the position of the PCB is accurately adjusted, the PCB is immediately pressed down and fixed by the pressing plate 28. This prevents the PCB from further deflecting and moving, and prevents excessive adjustment of the PCB position under the influence of air, further improving the accuracy of the PCB position adjustment. When the air in the blowing chamber 4 stops blowing upward, the magnetism of the electromagnet 30 flips and attracts the permanent magnet 31. At this time, the pressing plate 28 is away from the PCB, and then the rotating plate 22 can be rotated to a horizontal state.

[0040] In one embodiment of the present invention, the elastic member 34 is a spring, and of course it can also be other elastic components such as an elastic ball. The spring supports the pressure plate 28 and provides buffering during subsequent downward pressure.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0042] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
