Description

Technical Field

[0001] The utility model relates to the field of PCB board processing, in particular to a PCB board processing flip structure. Background Art

[0002] PCB board usually refers to printed circuit board, which is a basic component commonly used in electronic products. PCB board is used to support and connect electronic components, provide electrical connection and mechanical support. Circuits are formed on PCB board by printing, and electronic components are soldered on it to achieve circuit connection and function realization.

[0003] In order to facilitate the processing and production of PCB boards, it is necessary to use a PCB board processing flip structure to perform double-sided processing on the PCB board. For example, the prior art Chinese patent publication number "CN113438814A" discloses a flip-type PCB board processing equipment, which relates to the technical field of PCB board processing. A spot welding head is provided on one side of the workbench, and a placement groove for placing PCB boards is provided at the bottom of the spot welding head. A flip mechanism is provided on one side of the placement groove. The flip mechanism includes a clamping arm, and a movable clamping plate and a static clamping plate are arranged parallel to each other at the end of the clamping arm for clamping the PCB board. A rotating joint is provided on the clamping arm, which is used to drive the movable clamping plate and the static clamping plate at the end to rotate around the central axis of the clamping arm. A driving component is provided between the clamping arm and the workbench, which is used to drive the entire clamping arm to move in the spatial coordinate. In the process of spot welding, after the workbench completes spot welding on one side of the PCB board, the PCB board can be automatically flipped by the flip mechanism, and the PCB board can be flipped to the unprocessed side for spot welding. The PCB board can be directly spot welded on both sides without manual flipping, which improves the continuity of the circuit board spot welding work and improves the effect and efficiency of spot welding.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1 -4, a PCB board processing flip structure, comprising a frame 1, wherein two flip members 2 are arranged on the top of the frame 1, wherein one of the flip members 2 is driven to rotate by a flip assembly 3, and a plurality of electric clamps 4 for clamping one end of the PCB board are arranged inside the flip member 2, and a driving member 5 is also arranged inside the flip member 2, and the driving member 5 is used to drive the electric clamp 4 to move;

[0023] A clamping member 6 for clamping the other end of the PCB board is provided in the other flip member 2, and a limiting assembly 7 is provided between the flip member 2 and the frame 1, and the limiting assembly 7 is used to ensure that the flip member 2 can be aligned with the other flip member 2.

[0024] The electric clamp 4 has a wire connected to an external power source, and is used to clamp one end of the PCB board. In addition, the driving member 5 has the advantage of driving multiple pairs of the electric clamps 4 to move toward or away from each other to accommodate PCB boards of different lengths. The clamping member 6 cooperates with the electric clamp 4 to facilitate the clamping of a stable PCB board.

[0025] Furthermore, the flip assembly 3 includes a first fixed seat 31 fixedly installed on one side of the top of the frame 1, and a first motor 32 is fixedly installed on the top of the frame 1. The shaft end of the first motor 32 is rotatably connected to the first fixed seat 31 and a driving pulley 33 is fixedly installed.

[0026] Furthermore, a second fixing seat 35 is fixedly installed on the side of the frame 1 through a support frame 34, and a first rotating shaft 36 is rotatably connected in the second fixing seat 35. A driven pulley 37 is fixedly installed on one end of the first rotating shaft 36. A transmission belt 38 is sleeved between the active pulley 33 and the driven pulley 37. The shaft end of the first motor 32 drives the driven pulley 37 to rotate through the active pulley 33 and the transmission belt 38, thereby driving the first rotating shaft 36 to rotate. The first rotating shaft 36 drives the first flip frame 21 to rotate while rotating, thereby achieving the purpose of flipping the PCB board.

[0027] In more detail, the flip member 2 includes a first flip frame 21 and a second flip frame 22. The first flip frame 21 is fixedly installed on the other end of the first rotating shaft 36, and the second flip frame 22 is rotatably connected to the other side of the frame 1 through a second rotating shaft 25. A guide block 24 is slidably connected to the first flip frame 21 through a first guide groove 23, and the electric clamp 4 is fixedly installed on the side of the guide block 24.

[0028] In general, the driving member 5 includes a second motor 51 fixedly installed on the side of the first flip frame 21. The shaft end of the second motor 51 is located in the first guide groove 23 and is fixedly connected to a double-headed screw rod 52. The guide block 24 is threadedly connected to the double-headed screw rod 52. The second flip frame 22 itself cannot rotate, and needs to rotate under the drive of the first flip frame 21 after fixing the PCB board, so as to play a role in stably clamping the PCB board. The double-headed screw rod 52 is driven by the second motor 51 to drive a pair of the guide blocks 24 to move toward or away from each other, so as to adapt to PCB boards of different lengths.

[0029] In addition, the clamping member 6 includes a plurality of first springs 61 and a clamping plate 62. A mounting groove 63 is provided in the second flip frame 22. The first springs 61 are fixedly connected to the upper and lower sides of the mounting groove 63. The clamping plate 62 is fixedly installed on one end of a pair of first springs 61 facing each other. The clamping plate 62 can clamp one side of the PCB board.

[0030] Finally, the limit assembly 7 includes a positioning glass bead 71. The top of the frame 1 is located above the second rotating shaft 25 and is provided with a key groove 72 that is connected to the rotating shaft groove. The positioning glass bead 71 is slidably connected to the key groove 72 and conflicts with the side of the frame 1. The side of the frame 1 is provided with a second guide groove 73. The side of the second flip frame 22 is provided with a guide rod 74 that is slidably connected to the second guide groove 73. The outer periphery of the guide rod 74 is provided with a second spring 75. The two ends of the second spring 75 respectively conflict with the sides of the frame 1 and the second flip frame 22.

[0031] The specific operation is to use the second spring 75 to support the second flip frame 22. When the PCB board needs to be clamped, the second rotating shaft 25 is pulled to drive the second flip frame 22 to move backward, so as to facilitate the insertion and clamping of the PCB board. It should be noted that due to the effect of the positioning glass bead 71 conflicting with the side of the frame 1, the second flip frame 22 will not move at will and cause the PCB board to fall off. When the second rotating shaft 25 needs to be pulled, the positioning bead on the top of the positioning glass bead 71 needs to be pressed downward so that the positioning glass bead 71 can slide in the key slot 72. The key slot 72 is used to ensure that the second flip frame 22 can be aligned with the first flip frame 21 when sliding to clamp the PCB board, so as to prevent the PCB board from not being able to be clamped due to different angles.

[0032] Working mode: When working, the positioning bead of the positioning glass bead 71 is pressed, and the second rotating shaft 25 is pulled to make the positioning glass bead 71 slide and connect in the key slot 72, and the second rotating shaft 25 drives the second flip frame 22 to move backward, so that there is a space between it and the first flip frame 21 to facilitate the placement of the PCB board;

[0033] Then the second motor 51 drives the double-headed screw 52 to rotate. At this time, the electric clamp 4 moves toward or away from each other to a suitable position under the drive of the double-headed screw 52, ​​and then cooperates with the clamp 62 to clamp the two ends of the PCB board;

[0034] Then the first motor 32 drives the driven pulley 37 to rotate through the active pulley 33 and the transmission belt 38, thereby driving the first rotating shaft 36 to rotate. The first rotating shaft 36 rotates and drives the first flip frame 21 to rotate, thereby achieving the purpose of flipping the PCB board;

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
