Description

Technical Field

[0001] The present application relates to the technical field of board splitters, and in particular to a board splitter for producing and processing PCB boards. Background Art

[0002] The Chinese name of PCB circuit board is printed circuit board, which is the carrier of electrical connection of electronic components. PCB board splitter is a device that professionally splits the whole PCB board. Different models of splitters are used for splitting whole PCB boards of different sizes. There are automatic splitters and manual knife-type splitters. For example, when splitting a whole board with a larger area, the PCB board is fixed by a fixed mold, and then the small board is automatically split by a milling cutter. When the overall area is small and the small circuit boards are densely distributed, a circular knife cross-cutting manual knife method is usually adopted to directly cut this type of PCB board into strips. The small whole board is manually held and pushed towards the cutting groove. Under the cross-cutting action of the circular knife, the small circuit board is split and falls onto the material table. The efficiency of manual pushing is low, and the accuracy is difficult to guarantee. It is difficult to ensure the quality of PCB splitting. Therefore, the present application proposes a splitter for PCB board production and processing. Utility Model Content

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0025] like Figure 1-Figure 5 As shown, a PCB board production and processing machine proposed in one embodiment of the present application includes:

[0026] The base 1 has a groove 2 at the top of one end, and two transmission rollers 3 are rotatably arranged on the opposite sides of the inner wall of the groove 2. A transmission belt 4 is wound around the two transmission rollers 3. When the PCB board is separated, the whole board is placed on the transmission belt 4, and the transmission roller 3 is driven by the driving member to rotate, thereby driving the transmission belt 4 to transmit, thereby transmitting the PCB board, which is convenient for subsequent cutting and separation. The upper transmission surface of the transmission belt 4 is slightly higher than the top surface of the base 1;

[0027] The bracket 5 is arranged on the top of the base 1, and an electric push rod 6 is arranged on the bracket 5. A movable frame 7 is arranged at the piston end of the electric push rod 6. A guide rod whose end slides through the bracket 5 is arranged on the movable frame 7. A rotating shaft 8 is rotatably arranged on the movable frame 7, and the rotating shaft 8 corresponds to one of the transmission rollers 3. Preferably, the rotating shaft 8 is located directly above one of the transmission rollers 3. A pressing cylinder 9 is arranged on the rotating shaft 8. When the entire PCB board is placed on the conveyor belt 4, and one end of the entire PCB board is placed directly above one of the transmission rollers 3, the electric push rod 6 works, and its piston end drives the movable frame 7 to move downward, so that the pressing cylinder 9 is pressed and held against the PCB board. Since the rotating shaft 8 is located directly above one of the transmission rollers 3 Therefore, one of the transmission rollers 3 and the rotating shaft 8 indirectly presses the PCB board, and a driving mechanism 10 is provided on the base 1. The driving mechanism 10 is used to drive the rotating shaft 8 and one of the transmission rollers 3 to rotate synchronously in the opposite direction. The transmission roller 3 and the rotating shaft 8 are driven by the driving mechanism 10 to rotate synchronously in the opposite direction. When the transmission roller 3 is transmitted, the transmission belt 4 supports and transmits the PCB board as a whole, and when the rotating shaft 8 rotates synchronously in the opposite direction, the pressing cylinder 9 cooperates with one of the transmission rollers 3 to realize auxiliary transmission of one end of the PCB, so that the PCB board is limited by the pressing of the transmission belt 4 and the pressing cylinder 9 during transmission. When the transmission belt 4 stops transmitting, the PCB board is pressed and fixed by the transmission belt 4 and the pressing cylinder 9, so that it is not easy to be displaced;

[0028] The cutting mechanism 11 is arranged on the base 1 and is used for cutting the PCB board. When the PCB board is transported by the conveyor belt 4 and the pressing cylinder 9 and is transported to the position of the cutting mechanism 11, the transport is stopped so that the PCB board remains in a fixed state. The cutting mechanism 11 cuts the PCB board. Since the PCB board is in a fixed state, it will not be offset due to the stress of cutting, thereby ensuring the quality of the PCB board cutting and improving the practicality.

[0029] like Figure 4 As shown, in some embodiments, it is characterized in that the number of pressing cylinders 9 is two and both are slidably sleeved on the rotating shaft 8. The pressing cylinder 9 includes a first pressing portion 901 and a second limiting portion 902 connected to each other. The rotating shaft 8 is provided with an adjusting member 12 for adjusting the synchronous reverse sliding of the two pressing cylinders 9. Preferably, the first pressing portion 901 and the second limiting portion 902 are both cylindrical in structure, and the diameter of the second limiting portion 902 is larger than the diameter of the first pressing portion 901. When the pressing cylinder 9 is adjusted to press the PCB board, the spacing between the two pressing cylinders 9 can be adjusted by the adjusting member 12 according to the overall width of the PCB board, so that the first pressing portion 901 is pressed on the front side of the PCB board, the second limiting portion 902 overlaps the side of the PCB board, and the second limiting portions 902 of the two pressing cylinders 9 overlap the two sides of the PCB board respectively, thereby limiting the transmission of the PCB board, further improving the stability of the transmission of the PCB board, and improving the quality of PCB board cutting and splitting.

[0030] like Figure 4As shown, in some embodiments, the adjusting member 12 includes a bidirectional screw rod 1201, a cavity is opened in the rotating shaft 8, the bidirectional screw rod 1201 coaxially rotates and passes through the rotating shaft 8, and the outer surface of the rotating shaft 8 is opened with a through groove 1202 connected to the cavity, and both ends of the bidirectional screw rod 1201 are threadedly sleeved with movable blocks 1203, and connecting blocks are provided on the two movable blocks 1203. The two connecting blocks slide through the through groove 1202 and are respectively fixedly connected to the two pressure cylinders 9. The bidirectional screw rod 1201 is twisted to rotate, and under the action of the bidirectional thread and the sliding limit of the connecting block and the through groove 1202, the two movable blocks 1203 are driven to move in the opposite direction synchronously, thereby driving the two pressure cylinders 9 to move in the opposite direction synchronously, so as to adapt to the role of limiting the width of different PCB boards.

[0031] like Figure 4 As shown, in some embodiments, the outer surface of the first pressing portion 901 is sleeved with a rubber sleeve 13, and the outer surface array of the rubber sleeve 13 is constructed with a plurality of anti-slip convex strips. The bottom of the PCB board contacts the conveyor belt 4, which has a larger contact area, and the top of the PCB has a smaller contact area with the first pressing portion 901. By setting the rubber sleeve 13 and utilizing the deformable property of the rubber sleeve 13 material, the protective convex strips are constructed to increase the contact friction between the first pressing portion 901 and the PCB board, so that when the rotating shaft 8 rotates, sufficient transmission stress is applied to the PCB board to ensure the stability of the PCB board transmission, while also ensuring the stability of the clamping and fixing of the PCB board.

[0032] like Figure 5 As shown, in some embodiments, the driving mechanism 10 includes a mounting frame 1001 arranged on the base 1, and two worms 1002 are rotatably arranged on the mounting frame 1001. The opposite ends of the two worms 1002 are fixedly connected and the spiral rotation directions of the two worms 1002 are opposite. The end of one of the worms 1002 is connected to a first motor 1003 fixedly arranged on the mounting frame 1001, and a worm wheel 1004 is fixedly arranged on one of the transmission rollers 3 and the rotating shaft 8. The two worm wheels 1004 are respectively engaged with the two worms 1002. The first motor 1003 performs work, and its output shaft drives one of the worms 1003. 2 rotates, thereby driving the other worm 1002 to rotate synchronously. Under the transmission meshing of the two worms 1002 and the two worm wheels 1004, the transmission roller 3 and the rotating shaft 8 are driven to rotate synchronously. Since the spiral patterns of the two worms 1002 rotate in opposite directions, the transmission roller 3 and the rotating shaft 8 rotate synchronously in opposite directions. When the movable frame 7 moves downward, the worm wheel 1004 located on the rotating shaft 8 meshes and moves along the meshed worm 1002, so that the two are always kept in a meshing state. No matter how far the rotating shaft 8 and the transmission roller 3 are separated, the first motor 1003 can drive the transmission roller 3 and the rotating shaft 8 to rotate synchronously in opposite directions.

[0033] like Figure 2 and Figure 3As shown, in some embodiments, the cutting mechanism 11 includes a cutting frame 1101 arranged on the base 1, and a threaded rod 1102 is rotatably arranged on the cutting frame 1101, one end of the threaded rod 1102 is connected to a second motor 1103 fixedly arranged on the cutting frame 1101, and a movable plate 1104 is threadedly sleeved on the threaded rod 1102. Preferably, a limiting groove is provided on the cutting frame 1101, and the movable plate 1104 is slidably inserted in the limiting groove, and a third motor 1105 is provided on the movable plate 1104. The output shaft of the third motor 1105 is fixedly provided with a cutting blade 1106, and a discharge groove 1107 aligned with the cutting blade 1106 is provided on the base 1. Preferably, the cutting blade 1 The cutting blade of 106 is placed in the discharge groove 1107. After the PCB board is transmitted, the part to be cut is suspended in the discharge groove 1107. The third motor 1105 works, and its output shaft drives the cutting blade 1106 to rotate at high speed. The second motor 1103 works, and its output shaft drives the threaded rod 1102 to rotate. Under the action of the thread and the limit of the limit groove, the movable plate 1104 is driven to move, so that the cutting blade 1106 can cut and separate the PCB board. The second motor 1104 rotates forward and reverse, thereby driving the movable plate 1104 to move back and forth horizontally, so as to realize segmented cutting and separation of the PCB board, and the cut PCB board is discharged along the discharge groove 1107.

[0034] like Figure 2 As shown, in some embodiments, a supporting roller 14 is rotatably provided on the opposite side of the inner wall of the discharge trough 1107. When the PCB board is transferred into the discharge trough 1107, its portion to be cut overlaps the top of the supporting roller 14. The portion to be cut of the PCB board is supported by the supporting roller 14, thereby improving the cutting quality of the PCB board.

[0035] like Figure 2 and Figure 5 As shown, in some embodiments, support rods 15 are provided at both ends of the movable frame 7, and the free ends of the two support rods 15 are rotatably connected to pressure rollers 16, and a pulley assembly 17 is connected between the pressure rollers 16 and the rotating shaft 8. When the movable frame 7 moves downward, the pressure rollers 16 are driven to move downward synchronously through the support rods 15. After the PCB is transmitted, the part to be cut will be placed between the pressure rollers 16 and the supporting rollers 14 as it moves. Preferably, the pressure rollers 16 and the supporting rollers 14 are both covered with rubber pressure sleeves, and the deformable property of the rubber pressure sleeve material is utilized to enable the PCB to be cut between the pressure rollers 16 and the supporting rollers 14. To ensure that the PCB is placed between the two, and at the same time, the pressing roller 16 and the supporting roller 14 can also press and resist the PCB board, so that when the PCB board is cut, both ends of the PCB board located at the cutting position are clamped, so that the cutting quality is better. When the cutting is completed, with the transmission of the conveyor belt 4, when the rotating shaft 8 rotates, the pressing roller 16 can be driven to rotate synchronously through the linkage of the pulley assembly 17, so that the PCB board pressed and cut between the pressing roller 16 and the supporting roller 14 can be smoothly moved out, thereby improving practicality.
