Description

Technical Field

[0001] This utility model relates to the technical field of PCB board splitting devices, specifically a PCB board splitting device. Background Technology

[0002] PCBs, also known as printed circuit boards, are made of copper or plastic and provide electrical connections for electronic components. The main advantages of using PCBs are significantly reduced wiring and assembly errors, improved automation, and increased production efficiency. After the entire PCB is produced, individual boards need to be broken off from the substrate. Current methods involve manually breaking each board one by one or using a hand-held cutting device, which is inefficient. Furthermore, breaking or hand-cutting can result in uneven force, leading to uneven division and damage to the PCB's electrical circuits, components, and solder paths, affecting the PCB's quality. Hand-held cutting devices are also dangerous. Therefore, a PCB cutting device is needed to solve these problems. Utility Model Content

A servo motor 2 is located at the center of the lower surface of the operating table 1, and a mounting plate 201 is fixedly connected to the output shaft of the servo motor 2 extending towards the center of the upper surface of the operating table 1. The servo motor 2 is electrically connected to an external power supply through the control host 102. An electric slide 3 is located at the rear end of the operating table 1, running from left to right. A cutting tool is provided on the slider of the electric slide 3. The cutting motor 301 has its output shaft extending into the discharge port 103 and is equipped with a cutting blade. Both the electric slide table 3 and the cutting motor 301 are electrically connected to an external power source via the control host 102. A dust extraction port 302 is located on the side of the cutting motor 301, with its air inlet extending towards the cutting blade. The dust extraction port 302 connects to an external dust extraction device to remove dust generated during cutting. One end of a T-shaped bracket 4 is connected to the mounting plate 201 via mounting screws 401. A clamping unit 5 is located at the other end of the T-shaped bracket 4. Positioning protrusions 202 are located on the upper surface of the mounting plate 201. A positioning port 402 is provided at one end of the T-frame 4. The positioning port 402 cooperates with the positioning protrusion 202. The positioning port 402 and the positioning protrusion 202 can prevent misalignment of the T-frame 4. The clamping unit 5 includes an L-shaped frame 51, a clamping electric push rod 52, a clamping bar 53, a discharge electric push rod 54, and a push plate 55. The front side of the L-shaped frame 51 is fixedly connected to the other end of the T-frame 4, and the rear opening of the L-shaped frame 51 extends toward the discharge port 103. The left end of the L-shaped frame 51 is closed. The clamping electric push rod 52 is set above the L-shaped frame 51 by a bracket. The clamping bar 53 is movably arranged inside the L-shaped frame 51 and cooperates with the clamping electric push rod 54. The telescopic shaft of rod 52 is connected, and the discharge electric push rod 54 is set on the rear side of L-shaped frame 51. The push plate 55 is connected to the telescopic shaft of discharge electric push rod 54, and the push plate 55 can extend into L-shaped frame 51. The clamping electric push rod 52 and the discharge electric push rod 54 are electrically connected to an external power source through the control host 102. The left end of L-shaped frame 51 is closed, which can limit the insertion position of PCB substrate. By using clamping electric push rod 52 to drive clamping bar 53 to descend, the PCB substrate can be pressed and fixed inside L-shaped frame 51. By using discharge electric push rod 54 and push plate 55, the divided substrate can be pushed and dropped into storage basket 6.A storage basket 6 is provided on the left side of the control panel 1. An installation opening 104 is located at the center of the left side of the control panel 1. The storage basket 6 is detachably installed inside the opening 104. This detachable design facilitates cleaning of the inside of the storage basket 6. A slot 105 is provided on the inner side of the installation opening 104. A retaining ring 601 is provided around the top of the storage basket 6.

Between 04 and the storage basket 6, the segmented small boards are discharged through the discharge port 103, and the segmented substrates are stored in the storage basket 6. The PCB substrate is held by the clamping unit 5, and the servo motor 2 drives the clamping unit 5 to rotate, transferring the PCB substrate and the small boards above it to the discharge port 103. This causes the electric slide table 3 to drive the cutting motor 301 to move, and finally the cutting blade segments the small boards. All electrical components can be programmed and controlled by the control host 102.

[0019] The working principle of this utility model is as follows: The host 102 starts the servo motor 2, causing the clamping unit 5 to pass through the storage frame 6 and reach the front end of the operating table 1. The PCB substrate to be divided is inserted into the L-shaped frame 51. The clamping electric push rod 52 is activated, and the clamping bar 53 descends, pressing and fixing the PCB substrate. The small board protrudes from the front opening of the L-shaped frame 51. The switch is activated, and the PCB board rotates through the storage frame 6 to the discharge port 103. The cutting motor 301 starts, and the cutting blade rotates. The electric slide table 3 drives the cutting blade to cut the PCB board. The divided PCB board... The small board falls into the discharge port 103. A collection container can be placed below the discharge port 103 to receive it. After the slider of the electric slide table 3 reaches the other end, the servo motor 2 drives the clamping unit 5 to rotate and reset. When it reaches above the collection frame 6, the clamping bar 53 rises, and the discharge electric push rod 54 pushes the push plate 55 into the L-shaped frame 51, squeezing the PCB substrate out of the L-shaped frame 51 and letting it fall into the collection frame 6 for collection. After the pushing is completed, the push plate 55 resets, and the servo motor 2 drives the clamping unit 5 to the front end of the operating table 1. The above process is repeated to start the cutting of the next PCB board. The circuit connection involved in this utility model is a common means used by those skilled in the art. Technical inspiration can be obtained through limited experiments, and it belongs to the widely used prior art.
