Description

Technical Field

[0001] This utility model relates to the field of PCB, and in particular to an automated processing device for multilayer PCB circuit boards. Background Technology

[0002] Multilayer PCB processing equipment is a collection of devices used in the production of multilayer printed circuit boards to perform processing operations such as cutting, drilling, laminating, and etching of the board material. For example, the laminator can press the multilayer substrate and the prepreg together, and the drilling machine can complete the high-precision hole processing. Through the cooperation of various components, it ensures the electrical connection and physical structure formation of the multilayer PCB.

[0003] The patent announcement CN209546023U proposes a processing device for multilayer PCB boards. By adjusting the sliding positioning structure of the adjustment hole, the clamping distance of the U-shaped retaining rings on both sides can be adjusted for PCB boards of different lengths and batches, which effectively improves the flexibility of the U-shaped retaining rings. However, it relies on manual operation of the handle and pull pin to adjust the distance. For production lines with frequent model changes, the manual operation is inefficient and the positioning accuracy is easily affected by human factors. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, such as low efficiency of manual operation and easy influence of human error on positioning accuracy, the technical problem is to provide an automated processing device for multilayer PCB circuit boards.

[0005] The technical solution is as follows: An automated processing device for multilayer PCB circuit boards includes a mounting base. Two symmetrical sliding grooves are provided on both the left and right sides of the mounting base along the front-back direction. A bracket is slidably connected in each sliding groove. A screw is rotatably connected to the middle of both sides of the mounting base. Both ends of the screw are rotatably connected to the mounting base. When the screw rotates, because the bracket is threadedly connected to the screw, it can drive the bracket to slide along the sliding groove and subsequent limiting rods, achieving adaptive adjustment for processing positions of PCB boards of different sizes. A motor is fixedly connected to the middle of both sides of the mounting base. The output shaft of the motor passes through the mounting base and is fixedly connected to the outer end of the screw via a coupling. Limiting rods are fixedly connected to both sides of the mounting base. A bracket is slidably connected to the limiting rod, and the middle of the bracket is threadedly connected to the screw. The bracket has a slot adapted to a fixing plate. The fixing plate is snapped onto the bracket through the slot, achieving quick assembly and disassembly. The fixing plate has a fixing component for fixing the PCB board.

[0006] Preferably, the fixing assembly includes clamping blocks. Each fixing plate has two sets of clamping blocks, which fix the PCB board from the horizontal and vertical directions, respectively. The clamping blocks are slidably connected to the fixing plates. A spring is provided between the clamping blocks and the fixing plates. One end of the spring is fixedly connected to the clamping block, and the other end of the spring is fixedly connected to the fixing plate. A pressure sensor is fixedly connected to the front side of the clamping block. The pressure sensor is used to sense the clamping pressure on the PCB board. Controllers are fixedly connected to both the left and right sides of the mounting base. The controllers are electrically connected to the pressure sensor and the motor. When the clamping pressure detected by the pressure sensor exceeds the set range, the signal can be transmitted to the controller, which controls the motor to rotate forward and backward, adjusts the position of the bracket, and thus adjusts the clamping pressure of the clamping blocks on the PCB board.

[0007] Preferably, the device also includes an anti-slip pad, which is fixedly connected to the bottom of the mounting base. The anti-slip pad increases the friction between the device and the placement surface, prevents the device from sliding during processing, and improves placement stability.

[0008] Preferably, a rubber pad is also included. The pressure sensor is fixedly connected to the rubber pad, which can prevent the pressure sensor from directly contacting the PCB circuit board and causing damage, while not affecting the pressure detection accuracy.

[0009] Preferably, a dust cover is also included, which is fixedly connected to the mounting base to prevent dust from entering and thus avoid affecting the operating accuracy and lifespan of the device.

[0010] Preferably, a collection box is also included, which is fixedly connected to the mounting base to collect debris, waste liquid, etc. generated during the processing, making it convenient for centralized cleaning.

[0011] The beneficial effects are as follows: the bracket slot enables quick mounting of the fixing plate; the servo motor drives the screw to slide the bracket, precisely adjusting the spacing of the fixing plate to adapt to PCB boards of different sizes; the clamping block and spring provide flexible clamping; the pressure sensor senses the pressure in real time and transmits the signal to the controller, which in turn drives the motor to fine-tune the spacing, achieving efficient feeding and precise fixing, ensuring stable clamping of the PCB board before processing, effectively improving feeding efficiency and fixing accuracy, reducing manual intervention, and meeting the needs of automated processing.

Detailed Implementation

[0016] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0017] Example: An automated processing device for multilayer PCB circuit boards, such as... Figure 1-3 As shown, the assembly includes a mounting base 1, a slide groove 101, a bracket 2, a fixing plate 201, a screw 3, a motor 4, a limiting rod 5, and a fixing component. The mounting base 1 has two slide grooves 101 symmetrically formed on both its left and right sides along the front-back direction. The bracket 2 is slidably connected within each slide groove 101. The screw 3 is rotatably connected to the middle of both sides of the mounting base 1, with both ends of the screw 3 rotatably connected to the mounting base 1. When the screw 3 rotates, because the bracket 2 is threadedly connected to the screw 3, it can drive the bracket 2 to slide along the slide groove 101 and the subsequent limiting rod 5, thus enabling the mounting of PCBs of different sizes. For the adaptation and adjustment of the processing position, the motor 4 is fixedly connected to the middle of both sides of the mounting base 1. The output shaft of the motor 4 passes through the mounting base 1 and is fixedly connected to the outer end of the screw 3 through a coupling. The limiting rod 5 is fixedly connected to both sides of the mounting base 1. The bracket 2 is slidably connected to the limiting rod 5, and the middle of the bracket 2 is threadedly connected to the screw 3. The bracket 2 is provided with a slot that matches the fixing plate 201. The fixing plate 201 is snapped onto the bracket 2 through the slot to achieve quick assembly and disassembly. The fixing plate 201 is provided with a fixing component for fixing the PCB board. The fixing assembly includes clamping blocks 6, pressure sensors 7, springs 9, and controllers 8. Each fixing plate 201 has two sets of clamping blocks 6, which fix the PCB board from the horizontal and vertical directions respectively. The clamping blocks 6 are slidably connected to the fixing plate 201. The springs 9 are provided between the clamping blocks 6 and the fixing plate 201. One end of the spring 9 is fixedly connected to the clamping block 6, and the other end of the spring 9 is fixedly connected to the fixing plate 201. The pressure sensor 7 is fixedly connected to the front side of the clamping block 6. The pressure sensor 7 is used to sense the clamping pressure of the PCB board. The controllers 8 are fixedly connected to both the left and right sides of the mounting base 1. The controllers 8 are electrically connected to the pressure sensors 7 and the motor 4. When the clamping pressure detected by the pressure sensor 7 exceeds the set range, the signal can be transmitted to the controller 8, which controls the motor 4 to rotate forward and backward, adjusts the position of the bracket 2, and thus adjusts the clamping pressure of the clamping blocks 6 on the PCB board.

[0018] When the device is activated, the operator quickly mounts and adapts the fixed plate 201 using the slot of the bracket 2 according to the PCB board size. The motor 4 is started, driving the screw 3 to rotate. Because the bracket 2 is threadedly connected to the screw 3 and slides along the slide groove 101 and the limiting rod 5 of the mounting base 1, the rotation of the screw 3 causes the bracket 2 to slide back and forth, adjusting the spacing of the fixed plate 201. The PCB board is placed on the fixed plate 201, and the clamping block 6 is compressed, causing the spring 9 to compress or reset, achieving flexible clamping. The pressure sensor 7 senses the clamping pressure, converts it into an electrical signal, and transmits it to the controller 8. The controller 8, in conjunction with the motor 4, automatically fine-tunes the spacing of the bracket 2 to accurately adapt to PCB boards of different sizes, efficiently completing loading and fixing. Through the synergy of mechanical transmission and sensor control, stable clamping before processing is ensured.

[0019] like Figure 1 and Figure 3 As shown, the device also includes an anti-slip pad 10, which is fixedly connected to the bottom of the mounting base 1. It also includes a rubber pad 11, which is fixedly connected to the pressure sensor 7. Furthermore, it includes a dust cover 12, which is fixedly connected to the mounting base 1. Finally, it includes a collection box 13, which is fixedly connected to the mounting base 1.

[0020] During processing, the anti-slip pad 10 at the bottom of the mounting base 1 increases the friction with the placement surface, preventing device displacement and ensuring accurate drilling and other processing actions. The rubber pad 11 on the clamping block 6 isolates the PCB board from the clamping block 6, reducing wear and scratches caused by direct contact between the two. The dust cover 12 blocks drilling dust, preventing it from entering the connection between the screw 3 and the limiting rod 5, avoiding transmission jamming and component wear caused by dust, and extending the device's lifespan. The collection box 13 is used to temporarily store the processed PCB board or collect processing debris, facilitating subsequent unloading and cleaning, helping to maintain an orderly processing environment, and improving the convenience of the overall processing flow and equipment maintainability.

[0021] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
