Description

Technical Field

[0001] This invention relates to the field of circuit board manufacturing, and more specifically, to a wire straightening device for controlling circuit board manufacturing. Background Technology

[0002] A circuit board is a flat board used to assemble electronic components, such as computer motherboards and mobile phone boards. Circuit boards have many lines and components that can be connected to realize the functions of electronic components. In the production process of circuit boards, potting is required.

[0003] Circuit board potting is a process used to seal components and circuits on circuit boards. It is typically used to prevent the circuit board from being affected by external factors such as moisture and dust. The principle is to inject glue between the components and circuits on the circuit board, and then allow the glue to cure, forming a sealed protective layer that effectively protects the components and circuits on the circuit board and extends the life of the circuit board. In the current circuit board potting process, the circuit boards are first neatly placed in a customized frame, and glue is injected into the frame through a potting machine. However, some control circuit boards have wires that need to be straightened before potting to keep them vertical and prevent them from being covered by glue. Currently, the straightening of wires on control circuit boards is mostly done manually. However, after working for a long time, the efficiency of workers inevitably decreases, and the force of manual straightening cannot be precisely controlled, and it cannot be guaranteed that the straightened wires are in a vertical state, which may obstruct the passage of the potting machine nozzle. Summary of the Invention

[0004] In order to solve the technical problems existing in the prior art, a wire straightening device for controlling circuit board production is provided.

[0005] The technical solution is as follows: A wire straightening device for controlling circuit board production, comprising a frame; a straightening mechanism capable of straightening wires on a circuit board; and a material frame for storing straightened circuit boards; the straightening mechanism includes a conveying module for placing and conveying circuit boards; a straightening plate capable of simultaneously straightening all wires on circuit boards placed on the conveying module; a mounting bracket for fixing the straightening plate; a guide bracket disposed on the frame and capable of guiding the sliding of the mounting bracket; and an output shaft connected to the mounting bracket, capable of... The system includes: a cylinder I that provides power for the sliding of the mounting bracket; a pressing frame that is rotatably connected to the guide bracket and assists in straightening the wires on the circuit board; and a geared motor that provides power for the rotation of the pressing frame; multiple sets of C-shaped grooves are evenly spaced on the straightening plate, with the width of the groove opening being smaller than the width inside the groove; the pressing frame and the connecting rod for connecting with the guide bracket are at a certain inclination angle, so that when the pressing frame contacts the straightening plate, the contact side of the pressing frame with the straightening plate is exactly perpendicular to the horizontal plane.

[0006] As a further preferred embodiment, the correction plate and the conveying module do not directly contact each other, and the reserved distance between them is consistent with the thickness of the circuit board.

[0007] As a further preferred embodiment, the guide bracket is provided with a pushing assembly, which is used to push the circuit board after the wires have been straightened into the material frame. The pushing assembly includes two cylinders II symmetrically arranged on the guide bracket and started by the same switch; and a pushing frame connected to the output shaft of the two cylinders II at the same time, which can push the circuit board on the conveying module into the material frame.

[0008] As a further preferred embodiment, the size of the pusher is adapted to the material frame; the contact end of the pusher with the circuit board is a long strip with an opening.

[0009] As a further preferred embodiment, the frame is provided with a positioning element for aligning the material frame with the conveying module. The positioning element includes a guide frame that can slide on the support rod of the frame and is provided with a spring between it and the frame; and a wedge-shaped limiting rod that can slide synchronously with the guide frame and can limit the position of the material frame.

[0010] As a further preferred embodiment, the top of the wedge-shaped limiting rod protrudes from the frame, and the part protruding from the frame fits into the material frame, so that the material frame cannot move freely after being locked in it; the two ends of the part of the wedge-shaped limiting rod protruding from the frame have different shapes, one end is a right angle that fits into the corner of the material frame, and the other end is an inclined shape that facilitates the input or output of the material frame.

[0011] As a further preferred embodiment, the frame is also provided with a tilting assembly for conveying the circuit board inside the material frame to the left, including an electric push rod I that provides power to lift the material frame; and a right-angle push rod connected to the movable end of the electric push rod I and capable of lifting the material frame when it rises.

[0012] As a further preferred embodiment, the top of the right-angle push rod is provided with a protrusion that is the same thickness as the side wall of the material frame, which can limit the lifting end of the material frame and prevent it from tipping over due to excessive lifting.

[0013] As a further preferred embodiment, the frame is further provided with a conveying assembly for removing the material frame filled with circuit boards from the frame, including a conveying frame with the same height as the frame; an electric push rod II mounted on the conveying frame to provide power for conveying the material frame; and a right-angle push plate connected to the movable end of the electric push rod II and capable of contacting and pushing the material frame.

[0014] As a further preferred embodiment, the wedge-shaped limiting rod is provided with a toggle assembly, which can pry open the wedge-shaped limiting rod when the material frame is conveyed forward. The toggle assembly includes a connecting frame installed on the wedge-shaped limiting rod and capable of moving synchronously with it; and a top block capable of moving synchronously with the right-angle push plate and used in conjunction with the connecting frame. The contact end between the connecting frame and the top block is beveled, and after the top block passes through the beveled portion, the wedge-shaped limiting rod no longer limits the material frame.

[0015] The present invention has the following advantages: 1. The present invention uses a straightening mechanism to arrange circuit boards in rows using a conveying module. Then, a reduction motor drives a pressing frame to press the wires into the wire grooves on the straightening plate and limit the circuit board. Subsequently, cylinder I drives the straightening plate to lift, while straightening multiple wires with consistent force, so that the straightened wires are in a vertical state, which saves manpower and improves work efficiency. 2. By setting up the pusher assembly, the pusher frame is pushed by cylinder II, which can push the circuit board with the wire straightened into the material frame for placement. The long strip-shaped pusher frame can ensure that the circuit board can remain neat when it falls into the material frame. 3. By setting up positioning components and tilting components, and with the cooperation of wedge-shaped limiting rods and guide frames, the position of the material frame can be limited, so that it is aligned with the conveying module and cannot be moved at will. This makes it easy to push the circuit board into the material frame. Furthermore, by using electric push rod I and right-angle push rod to push one end of the material frame to lift it up, the circuit board can be placed to the left without manual adjustment. 4. By setting up the conveying component and the actuating component, starting the electric push rod II will allow the material frame to be conveyed outward from the frame under the action of the right-angle push plate. At the same time, the top block and the connecting frame will also pop open the wedge-shaped limit rod, so that it will not limit the material frame during the conveying process.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0030] A wire straightening device for controlling circuit board production, such as Figures 1-3As shown, the system includes a frame 1; a straightening mechanism 2 capable of straightening wires on a circuit board; and a material frame 8 for storing straightened circuit boards. The straightening mechanism 2 includes a conveying module 23 for placing and conveying the circuit boards, the height of which is slightly higher than the height of the side wall of the material frame 8; a straightening plate 25 capable of simultaneously straightening all wires on the circuit boards placed on the conveying module 23, wherein seven sets of C-shaped wire grooves are equally spaced on the straightening plate 25, each set containing two wire grooves, the width of the opening of the wire grooves being smaller than the width inside the grooves to prevent the wires from slipping out of the opening after entering the wire grooves; a space with the same thickness as the circuit board is reserved between the straightening plate 25 and the conveying module 23, and the length of the straightening plate 25 is adapted to the conveying module 23; and a mounting bracket 24 for fixing the straightening plate 25, the mounting bracket 24 providing support for the straightening plate. 25. Stable support; a guide bracket 21 mounted on the frame 1 to guide the sliding of the mounting frame 24, the mounting frame 24 being connected to the guide bracket 21 via four guide rods to make it more stable when rising or falling; a cylinder I 22 connected to the mounting frame 24 via an output shaft to provide power for the sliding of the mounting frame 24; a pressing frame 27 rotatably connected to the guide bracket 21 to assist the circuit board in straightening the wires, the pressing frame 27 and the connecting rod for connecting to the guide bracket 21 having a certain inclination angle, the pressing frame 27 being perpendicular to the horizontal plane on the side of the pressing frame 27 contacting the straightening plate 25 when it contacts the straightening plate 25, and guiding the straightening plate 25 when it rises to ensure that it can straighten the wires to a vertical position; and a geared motor 26 to provide power for the rotation of the pressing frame 27.

[0031] like Figure 1 and Figure 4 As shown, a pusher assembly 3 is provided on the guide bracket 21. The pusher assembly 3 is used to push the circuit board after the wires have been straightened into the material frame 8. It includes two cylinders II 31 symmetrically arranged on the guide bracket 21. The two cylinders II 31 are started by the same switch. The pusher frame 32 is connected to the output shaft of the two cylinders II 31 and can push the circuit board on the conveying module 23 into the material frame 8. The size of the pusher frame 32 is adapted to the material frame 8. The contact end of the pusher frame 32 with the circuit board is a long strip with an opening, so that the circuit board can be neatly arranged when the circuit board is placed on the conveying module 23.

[0032] When straightening the wires on the circuit board, the worker only needs to place the circuit board on the long strip-shaped part on the left side of the pusher 32 and use the conveyor module 23 to convey it backward. At the same time, the wires on the circuit board are inserted into the corresponding wire grooves on the straightening plate 25. After the surface of the conveyor module 23 is full of circuit boards, the conveyor module 23 is turned off and the reduction motor 26 is started. The pressing frame 27 is rotated down to contact the straightening plate 25. Then the cylinder I 22 is started to push the mounting frame 24 upward. Under the dual guidance of the guide bracket 21 and the pressing frame 27, the straightening plate 25 can rise vertically. At the same time, all the wires on the circuit boards on the conveyor module 23 are straightened. The efficiency is greatly improved and the wires are kept vertical. The pressing frame 27 can also block the circuit board to prevent the circuit board from being lifted during the straightening process, which would prevent the wires from being straightened. Example 2

[0033] Based on Example 1, to ensure that the circuit board can be accurately placed within the material frame 8, such as... Figure 1 , Figure 5 and Figure 6 As shown, a positioning component 4 is provided on the frame 1. The positioning component 4 is used to align the material frame 8 with the conveying module 23. It includes a guide frame 42 and a wedge-shaped limiting rod 41. The guide frame 42 is slidably provided on the two support rods on the left side of the frame 1. A spring is provided between the frame 1 and the two guide frames 42. The wedge-shaped limiting rod 41 is connected to the two guide frames 42. Its top protrudes from the frame 1, and its protruding part fits into the material frame 8. After the material frame 8 is inserted, it cannot move freely. The two ends of the protruding part of the wedge-shaped limiting rod 41 have different shapes. The rear end is right-angled and can fit into the corner of the material frame 8. The front end is inclined and can guide the material frame 8 when it is input or output.

[0034] like Figure 1 , Figure 7 and Figure 8 As shown, the frame 1 is also equipped with a tilting component 5, which is used to transport the circuit board inside the material frame 8 to the left. The tilting component 5 includes an electric push rod I 51 and a right-angle push rod 52. The electric push rod I 51 is installed on the frame 1 at the bottom of the material frame 8 and can provide power for lifting the material frame 8. The right-angle push rod 52 is connected to the movable end of the electric push rod I 51 and can lift the material frame 8 when it rises. The top of the right-angle push rod 52 is provided with a protrusion that is consistent with the thickness of the side wall of the material frame 8. The distance between the protrusion and the straight part of the right-angle push rod 52 is greater than the thickness of the material frame 8. When the material frame 8 is lifted, the protrusion can protect it from tipping over and prevent it from tipping over due to excessive lifting.

[0035] Before placing the material frame 8 on the frame 1, the guide frame 42 can be pulled to move the wedge-shaped limiting rod 41 to the left. Then, the material frame 8 is inserted along the inclined part of the front of the wedge-shaped limiting rod 41, so that the wedge-shaped limiting rod 41 protrudes from the frame 1 and surrounds the material frame 8, preventing the material frame 8 from shaking freely. Then, the guide frame 42 is released, and the wedge-shaped limiting rod 41 is reset under the action of the spring, so that the material frame 8 is in contact with the conveying module 23. After the pushing component 3 pushes the circuit board into the material frame 8, the worker can start the electric push rod I 51 and use the right-angle push rod 52 to lift the right end of the material frame 8, causing it to tilt. The circuit board inside slides along the inclined surface to its left side without manual adjustment. Example 3

[0036] Based on Example 2, to facilitate the conveying of the material frame 8 by workers, such as Figure 1 , Figure 9 and Figure 10 As shown, a conveying assembly 6 is also provided on the frame 1. The conveying assembly 6 is used to remove the material frame 8 filled with circuit boards from the frame 1. It includes a conveying frame 61, an electric push rod II 62, and a right-angle push plate 63. The height of the conveying frame 61 is the same as that of the frame 1. The electric push rod II 62 is installed on the conveying frame 61 and can provide power for conveying the material frame 8. The right-angle push plate 63 is set on the movable end of the electric push rod II 62, and its lateral part slides in contact with the material frame 8. When the electric push rod II 62 is activated to retract its movable rod, the lateral part of the right-angle push plate 63 can push the material frame 8 back along the conveying frame 61.

[0037] like Figure 1 , Figure 11 and Figure 12 As shown, a toggle assembly 7 is provided on the wedge-shaped limiting rod 41. The toggle assembly 7 can pry open the wedge-shaped limiting rod 41 when the material frame 8 is conveyed forward. It includes a connecting frame 71 and a top block 72. The connecting frame 71 is located on the left side of the wedge-shaped limiting rod 41 and can move synchronously with the wedge-shaped limiting rod 41. The top block 72 is located at the bottom end of the vertical part of the right-angle push plate 63 and can move synchronously with it. It can also contact the connecting frame 71. The contact end between the connecting frame 71 and the top block 72 is beveled. When the top block 72 slides forward with the right-angle push plate 63, it will pass through the beveled part of the connecting frame 71, causing the connecting frame 71 and the wedge-shaped limiting rod 41 to move to the left and no longer limit the material frame 8.

[0038] After the material frame 8 is filled with circuit boards, the worker can start the electric push rod II 62 to pull the right-angle push plate 63 forward. During this process, the top block 72 will first contact the inclined part of the connecting frame 71 and drive the connecting frame 71 to the left. The wedge-shaped limit rod 41 will then move to the left and no longer limit the material frame 8. Subsequently, the horizontal part of the right-angle push plate 63 will contact the material frame 8 and push the material frame 8 to slide outward along the conveyor frame 61, thereby completing the output of the material frame 8 and reducing the consumption of labor costs.
