Description

Technical Field

[0001] The present invention relates to the technical field of PCB board processing, and more particularly to a board splitting device for PCB board processing. Background Art

[0002] A PCB board, also known as a printed circuit board, is an important electronic component, a support for electronic components, and a carrier for the electrical interconnection of electronic components. Since it is made by electronic printing technology, it is called a "printed" circuit board. During the processing of a PCB board, it needs to be split and cut.

[0003] Patent Publication No. CN219788472U discloses a board splitting machine for PCB board processing, including a chassis. A board cutting blade for cutting the board is connected to the lower side of the chassis. A processing table for support is arranged below the board cutting blade. A positioning component is connected to the processing table. The positioning component includes: a pressure sensor arranged on the processing table; a suction fan arranged on one side of the processing table; a spiral suction pipe arranged inside the processing table; and suction pipes uniformly arranged on the spiral suction pipe. By providing the positioning component, the PCB board is placed on the processing table and cut using the board cutting blade. The suction fan sucks air through the spiral suction pipe and the suction pipes to generate negative pressure at the position of the placement surface of the PCB board, and the pressure difference presses the PCB board tightly against the top of the processing table to achieve board positioning and ensure the processing effect.

[0004] When the above device performs a board splitting operation on a PCB board component, it realizes the function of pressing and fixing the PCB board component to improve the accuracy. However, in the actual board splitting process, it is often necessary to cut multiple board components. The above device lacks a corresponding feeding function and can only rely on manual handling or additional feeding equipment for cutting, which is labor-consuming and increases the processing cost. Therefore, a board splitting device for PCB board processing is proposed here to solve the above problems. Summary of the Invention

Subsequently, the PCB board body 26 is sequentially conveyed to the board-splitting and cutting station by controlling the rotation of the conveying tray 21. After being conveyed to the cutting position where the cutting device 292 is located, the cutting device 292 is controlled to move downward, and then the PCB board body 26 placed inside the support plates 25 can be cut and split. Processing is carried out in this way, which saves more manpower, and compared with manual feeding operation, it saves more manpower.

A limiting plate 289 is fixedly connected to the top of the auxiliary frame 294. The limiting plate 289 penetrates through the rectangular plate 293. After the first motor 298 works, it drives the first bidirectional threaded rod 296 to rotate;

[0035] A third electric push rod 299 is fixedly connected to the inner side of the frame plate 27. One end of the third electric push rod 299 is fixedly connected with the mounting block 28. After the third electric push rod 299 works, it pushes and pulls the mounting block 28. A lifting plate 281 is slidably connected to the inner side of the frame plate 27.

After the fourth electric push rod 284 works, it pushes and pulls the moving block 282;

[0036] A second bidirectional threaded rod 287 is rotatably connected inside the rectangular frame 24. The second bidirectional threaded rod 287 extends outside the rectangular frame 24. The second bidirectional threaded rod 287 sequentially penetrates through the two supporting plates 25 and is threadedly connected with the supporting plates 25. A fixing plate 288 is arranged inside the supporting plate 25. A limiting plate 289 is fixedly connected to one side of the fixing plate 288. The limiting plate 289 extends outside the supporting plate 25. A reed 271 is fixedly connected to the outside of the supporting plate 25. The reed 271 is fixedly connected to the inner side of the limiting plate 289. After the second bidirectional threaded rod 287 rotates, it drives the two outer supporting plates 25 to move towards or away from each other. A second motor 272 is fixedly connected to the top of the U-shaped plate 22. The second motor 272 is fixedly connected with a first gear 273 through an output shaft. A second gear 274 is fixedly connected to the outside of the round rod 23. The first gear 273 is arranged on one side of the second gear 274, and the first gear 273 meshes with the second gear 274. After the first gear 273 rotates, it drives the second gear 274 to rotate.

[0037] In actual operation, when the device is used, the device is first powered on, and the PCB body 26 to be cut is placed between the two support plates 25 on one side of the rectangular frame 24. When placing the PCB body 26, it is necessary to ensure that there is enough space between the PCB body 26 and the rectangular frame 24 to facilitate the insertion of the subsequent push plate 283. First, the second bidirectional threaded rod 287 is rotated, and the second bidirectional threaded rod 287 drives the two support plates 25 to move in opposite directions or in opposite directions, so as to adjust the distance between the two, and can match the placement and processing requirements of PCB bodies 26 of different sizes. When placing the PCB body 26, the two fixing plates 288 on the inner side of the support plate 25 are bent to both sides and the PCB body 26 is placed between the two. The elastic force of the spring 271 will prompt the two fixing plates 288 to move toward the PCB body 26 and squeeze it with a certain force. This force of squeezing can just make the PCB body 26 be in the center position, ensuring stability during the transportation process, and will not cause excessive squeezing to cause subsequent PCB body 26 to be blocked during pushing and processing.

[0038] After the second motor 272 starts working, it drives the first gear 273 to rotate, the first gear 273 drives the second gear 274 to rotate, the second gear 274 drives the round rod 23 to rotate, and the round rod 23 drives the conveying tray 21 to rotate. According to the above connection relationship, it can be known that the PCB board 26 on the conveying tray 21 can be sequentially conveyed to the bottom of the cutting device 292 to be cut;

[0039] During specific cutting, first, the fifth electric push rod 285 works to push the lifting plate 281 upwards, and the lifting plate 281 drives the moving block 282 to rise, and the moving block 282 drives the pushing plate 283 to move upwards to the gap between the PCB board 26 and the rectangular frame 24, and then the fourth electric push rod 284 works and pushes the moving block 282, and the moving block 282 drives the pushing plate 283 to move, and the pushing plate 283 moves and pushes the PCB board 26 to the horizontal direction where the cutting device 292 is located, when the cutting position on the PCB board 26 moves to the bottom of the cutting device 292;

[0040] First, the second electric push rod 295 pushes the auxiliary frame 294 downward. After the auxiliary frame 294 drives the push plate 297 to move downward to one side of the limit plate 289, the first motor 298 drives the first bidirectional threaded rod 296 to rotate. The first bidirectional threaded rod 296 drives the two push plates 297 to move towards each other. The push plate 297 moves to push the limit plate 289, and the limit plate 289 drives the fixed plate 288 to move to clamp the PCB board body 26, so as to ensure that the PCB board body 26 can be stably cut. Subsequently, the first electric push rod 291 pulls the connecting plate 29 downward, and the connecting plate 29 drives the cutting device 292 to move downward to contact and cut the PCB board body 26. During this period, the third electric push rod 299 works to horizontally push the mounting block 28. From the above connection relationship, it can be known that the horizontal movement of the cutting device 292 can be controlled, so that it can smoothly cut and separate the PCB board body 26. The cut board pieces then fall on the guide plate 286 and slide off, and the user only needs to receive the discharge end of the guide plate 286. Based on the above steps, the stable transportation of the PCB board body 26 is realized, and after being transported to the cutting station, it automatically cuts and separates the board, and guides and conveys the cut board pieces, which is beneficial to the user's collection. The above entire process does not require too much manual participation, greatly saving manpower, and the process is simple and convenient, which is beneficial to ensuring the processing efficiency. Processing with this operation saves more manpower and has strong practicability.

[0041] The above are all the preferred embodiments of the present invention, and the protection scope of the present invention is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the protection scope of the present invention.
