Description

Technical Field

[0001] The present invention relates to the technical field of transfer devices, and particularly to a transfer device based on circuit board manufacturing. Background Art

[0002] A circuit board, also known as a printed circuit board or printed wiring board, is a board-like structure that uses printing technology to fabricate connection lines and pads of circuit components on an insulating substrate, providing electrical connection and mechanical support for electronic components. It consists of an insulating substrate, conductive lines, pads, vias, etc. During the manufacturing process of circuit boards, there are differences in production speeds among different processes. The buffering and temporary storage functions of the transfer device can play a buffering role between processes, storing a certain number of circuit boards to coordinate the production rhythm of different processes, avoid production bottlenecks or equipment waiting phenomena, and improve the operating efficiency of the entire production line.

[0003] The functional structure of a circuit board transfer device includes: a carrying platform and a conveyor belt for the stable placement and transmission of circuit boards; a driving motor and transmission components to provide power and transmit it to the conveying system, and a positioning device and a guiding mechanism to ensure the precise docking and stable path of the circuit boards. With the controller as the core, combined with an operation interface, parameter setting, operation monitoring, and drive control are realized.

[0004] During the manufacturing process of circuit boards, it is necessary to transfer circuit boards at different process positions. When transferring circuit boards, circuit boards of the same process need to be concentrated and placed on a transfer device for transfer. Multiple circuit boards are stacked together, and the air between the circuit boards is squeezed and lost under the action of gravity. This will cause the air pressure between the circuit boards to decrease, and the circuit boards will be pressed together by the atmospheric pressure. This will make it difficult to quickly and accurately separate the circuit boards in subsequent processes, and the pressure between the circuit boards will cause fine lines to be squeezed and broken. For this reason, we propose a transfer device based on circuit board manufacturing. Summary of the Invention

[0005] One technical problem to be solved by the present application is that circuit boards are stacked together, resulting in difficulty in quickly separating the circuit boards and the lines being squeezed and broken.

[0011] Preferably, the locking member 2 includes two baffles slidably connected to the inside of the upper part of the support plate. Locking blocks 4 are arranged on the opposite sides of the two baffles. One end of one of the pulling rods away from the pulling plate abuts against the side of the baffle close to the pulling rod. A guiding member for stabilizing the sliding of the baffle is arranged inside the support plate. A driving member 2 for driving the baffle to move is arranged inside the upper part of the base.

[0012] Preferably, the guiding member includes guiding blocks arranged at the upper and lower parts on the adjacent sides of the two baffles. A plurality of guiding grooves 2 are formed in the upper part inside the support plate, and the guiding blocks are slidably connected to the inside of the guiding grooves 2.

[0013] Preferably, the second driving member includes a first driving magnet disposed on a side of the baffle away from the fourth locking block.

[0016] The present invention has at least the following beneficial effects: 1. When the circuit board is placed on the upper part of the loading plate, the gravity exerted by the loading plate on the synchronous belt can be increased. The circuit board pushes the two loading plates to move downward. The loading plate drives the synchronous belt to rotate and drives the synchronous pulley to rotate. The rotation of the synchronous pulley will drive and wind the clockwork spring. The circuit board pushes the moving plate to move downward along the sliding rod. The moving plate pulls the pulling plate to move while rotating. The pulling plate pulls the pull rod to slide out of the inner part of the first guiding groove. At this time, the locking of the pull rod on the loading plate is released. The pull rod pushes the locking rod to move. The locking rod pushes the third locking block to rotate 90 degrees. The third locking block blocks the upper part of the loading plate. Thus, it can prevent the circuit board from sliding upward and detaching from the loading plate during transfer. Through the dense arrangement between multiple loading plates, the functions of stack storage and anti-falling of the circuit board can be realized.

[0017] 2. The pull rod of the unloaded loading plate always gets stuck inside the first guiding groove, preventing the unloaded loading plate from moving downward. When a carrier plate is placed on the upper part of the last loading plate, the pull rod will retract into the loading plate. At this time, the baffle loses support. The second locking magnet pushes the first locking magnet, the baffle, and the fourth locking block to slide toward the side close to the loading plate. The fourth locking block will get stuck on the upper part of the loading plate. The lowermost loading plate abuts against the upper part of the base, and the uppermost loading plate will not move downward. Thus, it can prevent the loading plate from moving upward when the device is moving. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment 1: Please refer to Figure 1-7 , the present invention provides a technical solution: A transfer device based on circuit board manufacturing, including a base 1, a plurality of uniformly distributed universal wheels 11 are arranged at the lower part of the base 1, a push rod 12 is arranged on the left side of the base 1, support plates 13 are arranged on both the left and right sides inside the base 1, and a loading member 2 for loading circuit boards is arranged inside the base 1; The base 1, as the base of the device, has the characteristic of a low center of gravity. The universal wheels 11 have a braking function. The push rod 12 can be used as a pushing fulcrum for moving the base 1, and the support plates 13 can be kept perpendicular to the base 1; The outer wall of the support plate 13 is sleeved with a synchronous belt 22, and a plurality of uniformly distributed loading plates 24 are arranged on the outer wall of the synchronous belt 22. A control member 3 for controlling the movement of the loading plate 24 is arranged inside the loading plate 24; Further, the loading member 2 includes synchronous wheels 21 rotatably connected to the upper and lower parts inside the support plate 13, and the synchronous belt 22 is sleeved on the outer peripheries of two synchronous wheels 21 on the same side; Further, a clockwork spring 23 is arranged at the front end of the lower synchronous wheel 21, and one end of the clockwork spring 23 away from the synchronous wheel 21 is arranged inside the base 1; When the circuit board is placed on the upper part of the loading plate 24, the gravity exerted by the loading plate 24 on the synchronous belt 22 can be increased. The circuit board pushes the two loading plates 24 to move downward. The loading plate 24 drives the synchronous belt 22 to rotate and drives the synchronous wheel 21 to rotate. The rotation of the lower synchronous wheel 21 will drive and wind the clockwork spring 23, causing the clockwork spring 23 to contract. Through the dense arrangement between the multiple loading plates 24, the stackable access of the circuit boards can be realized. Since there is a distance between the two loading plates 24, physical contact between the two circuit boards can be avoided, thereby avoiding the adhesion of the circuit boards; The control member 3 includes a moving plate 31 slidably connected to the upper part of the loading plate 24. Two uniformly distributed sliding rods 32 are arranged in the middle of the loading plate 24. The sliding rods 32 are slidably connected to the inside of the middle part of the moving plate 31. Pulling plates 33 are rotatably connected to the front and rear right sides of the moving plate 31. One end of the pulling plate 33 away from the moving plate 31 is rotatably connected to a pull rod 34. Guide grooves 35 are respectively formed on the front and rear sides of the outer wall of the support plate 13. The pull rod 34 slides inside the guide groove 35. A first driving member 4 for driving the movement of the pull rod 34 is arranged inside the loading plate 24. A first locking member 5 for locking the circuit board is arranged inside the loading plate 24. A second locking member 6 for controlling the movement of the loading plate 24 is arranged inside the support plate 13; When the circuit board is placed on the upper part of the first loading plate 24, it will first push the moving plate 31 to move downward along the sliding rod 32. When the moving plate 31 moves, it can pull the end of the pulling plate 33 close to the moving plate 31 to rotate downward and move at the same time. At this time, the pulling plate 33 will pull the pull rod 34 to slide and slip out of the inside of the guide groove 35. At this time, the locking of the loading plate 24 by the pull rod 34 will be released; Further, the first locking member 5 includes a locking rod 51 rotatably connected to the upper part inside the pull rod 34. One end of the locking rod 51 away from the pull rod 34 is rotatably connected to a third locking block 52. The two third locking blocks 52 are respectively rotatably connected to the front and rear sides inside the loading plate 24; When the pull rod 34 moves forward, it will simultaneously push the locking rod 51 to move. The front end of the locking rod 51 will push the third locking block 52 to rotate by 90 degrees. When the third locking block 52 stops rotating, it will block the upper part of the loading plate 24, thereby preventing the circuit board from sliding upward and disengaging from the loading plate 24 during transfer. When the device is fully loaded, the uppermost loading plate 24 will not move downward; Further, the second locking member 6 includes two baffles 61 slidably connected to the upper inner part of the support plate 13. On the far sides of the two baffles 61, there are fourth locking blocks 62 provided. One end of a pull rod 34 away from the pull plate 33 abuts against the side of the baffle 61 close to the pull rod 34. A guiding member 7 for stabilizing the sliding of the baffle 61 is provided inside the support plate 13, and a second driving member 8 for driving the baffle 61 to move is provided inside the upper part of the base 1; Further, the second driving member 8 includes a first driving magnet 81 provided on the side of the baffle 61 away from the fourth locking block 62. The front and rear sides inside the support plate 13 are both provided with second driving magnets 82, and the second driving magnets 82 and the first driving magnet 81 are located on the same straight line; The first driving magnet 81 and the second driving magnets 82 are opposite in polarity. The second driving magnets 82 and the first driving magnet 81 have a tendency to push the baffle 61 to move toward the side close to the pull rod 34. When the pull rod 34 is not unlocked, it will push the baffle 61 and the first driving magnet 81 to move toward the direction close to the second driving magnets 82. At this time, the fourth locking block 62 will retract into the support plate 13 together with the baffle 61. At this time, the side of the baffle 61 close to the pull rod 34 is at the same height as the first guiding groove 35. When the pull rod 34 slides inside the first guiding groove 35, it will not be blocked by the baffle 61. When placing a circuit board on the upper part of the loading plate 24, it will cause the pull rod 34 to be unlocked and disengage from the inside of the first guiding groove 35. The pull rod 34 inside the empty loading plate 24 will slide downward to abut against the baffle 61 to prevent the baffle 61 from moving. After the loading plate 24 loses the locking of the pull rod 34, it will be pushed downward by the circuit board. However, the pull rod 34 of the upper empty loading plate 24 will always be stuck inside the first guiding groove 35, preventing the empty loading plate 24 from moving downward. When a carrier plate is placed on the upper part of the last loading plate 24, the pull rod 34 will retract into the loading plate 24. At this time, the baffle 61 loses support, and the second driving magnets 82 push the first driving magnet 81, the baffle 61 and the fourth locking block 62 to slide toward the side close to the loading plate 24. The fourth locking block 62 will be stuck on the upper part of the loading plate 24. The lowermost loading plate 24 abuts against the upper part of the base 1, and the uppermost loading plate 24 will not move downward. At this time, it can prevent the loading plate 24 from moving upward when the device is moving; When taking the circuit board, the operator can push the uppermost push circuit board upward. At this time, the circuit board is pushed upward, and the circuit board will push the locking block three 52 to rotate upward. At the same time, the moving plate 31 loses the extrusion of the circuit board, and the driving spring 42 will push the driving plate 41 and the pull rod 34 to move. The pull rod 34 is pushed back under the combined action of the locking rod 51 and the driving spring 42 to push the baffle 61, the locking block four 62 and the driving magnet one 81 to move in the direction of the driving magnet two 82. When the circuit board is taken out from the upper loading plate 24, the clockwork spring 23 will rebound to push the synchronous pulley 21 to rotate, driving the synchronous belt 22 to rotate, thereby driving the loading plate 24 to move upward. At this time, the pull rod 34 inside the second loading plate 24 will move upward to one side of the baffle 61. Repeat taking the circuit board until the lowermost loading plate 24 moves to the uppermost position to realize the access of the circuit board.

[0022] Further, the driving member one 4 includes a driving plate 41 arranged in the middle of the pull rod 34. A driving spring 42 is arranged on the left side of the driving plate 41. The driving spring 42 is sleeved on the outer periphery of the pull rod 34. Driving grooves 43 are opened on the front and rear sides inside the loading plate 24. The driving plate 41 slides inside the driving grooves 43. One end of the driving spring 42 away from the driving plate 41 is arranged inside the driving grooves 43; When the circuit board is placed on the upper part of the moving plate 31, the pull rod 34 can push the driving plate 41 to squeeze the driving spring 42 when moving. When removing the circuit board, the driving spring 42 can push the driving plate 41 and the pull rod 34 to move back by relaxation.

[0023] Further, the guiding member 7 includes guiding blocks 71 arranged on the upper and lower parts on the adjacent sides of the two baffles 61. A plurality of second guiding grooves 72 are opened on the upper part inside the support plate 13. The guiding blocks 71 are slidably connected inside the second guiding grooves 72; Through the cooperation between the guiding blocks 71 and the second guiding grooves 72, the baffle 61 can be kept vertical on the upper and lower sides when moving, preventing the baffle 61 from jamming caused by the inclination of the baffle 61.

[0024] Embodiment 2: Please refer to Figure 8-9 , the present invention provides a technical solution: Installation boxes 25 are abutted against the left and right sides inside the base 1. A handle 26 is arranged on the front side of the installation box 25. A plurality of uniformly distributed locking blocks one 27 are arranged on the outer wall of the installation box 25. Locking grooves 28 are opened on the left and right sides of the front part of the base 1. A plurality of locking blocks two 29 are arranged inside the base 1. The installation box 25 and the plurality of locking blocks one 27 are both abutted inside the locking grooves 28; Further, a rotating shaft 210 is rotatably connected inside the mounting box 25. One end of a clockwork spring 23 is disposed on the outer periphery of the rotating shaft 210, and the other end of the clockwork spring 23 away from the rotating shaft 210 is disposed on the inner wall of the mounting box 25. A pin hole 211 is formed at the rear side of the rotating shaft 210, and the shape of the front end of the synchronous pulley 21 matches that of the pin hole 211. The first locking block 27 and the second locking block 29 are strong magnets, and are arranged with opposite poles facing each other. Since the clockwork spring 23 needs to be kept in a contracted state frequently, this will cause the service life of the clockwork spring 23 to decrease. Therefore, the clockwork spring 23 is designed to be replaceable, reducing the maintenance duration caused by the damage of the clockwork spring 23. The synchronous pulley 21 is designed to have the same shape as the pin hole 211. Push the mounting box 25 into the inside of the locking groove 28, the synchronous pulley 21 will be inserted into the inside of the pin hole 211, then rotate the handle 26 to drive the mounting box 25 to rotate, so that the first locking block 27 and the second locking block 29 face each other, and then pull the handle 26 outward, the handle 26 drives the first locking block 27 to approach the second locking block 29. Thus, the clockwork spring 23 can be installed quickly, reducing the maintenance time for the damage of the clockwork spring 23.
