Description

Technical Field

[0001] This utility model relates to the technical field of PC board cutting equipment, specifically a PC board cutting device with angle adjustment function. Background Technology

[0002] With the rapid development of the electronic information industry, PC boards (printed circuit boards) are an indispensable key component of various electronic devices. The precision and efficiency of their manufacturing process have attracted much attention. In the production process of PC boards, cutting and processing is an extremely important link, which directly affects the quality and performance of PC boards and the stability of subsequent electronic products.

[0003] A search revealed that patent publication number CN118253889B discloses a laser cutting device for producing engineering plastic PC sheets, including an operating table mechanism and a drive mechanism mounted on the operating table mechanism. A laser cutting mechanism is installed at the lower end of the drive mechanism. A cooling mechanism is provided at the lower end of the laser cutting mechanism. The cooling mechanism includes a cooling sleeve fitted around the laser cutting head. One end of the cooling sleeve is connected to an upper air pipe. A spiral groove is formed inside the cooling sleeve, and a feed hole is formed at the upper end of the spiral groove wall. The feed hole is connected to the upper air pipe. This device uses two methods to cool both the laser cutting head and the plastic PC sheet simultaneously, greatly improving cooling efficiency. The gas flow can drive the tilting fan blades, rotating ring, and connecting ring to rotate, disturbing the airflow so that the airflow can be blown downwards evenly, and the atomized liquid sprayed from the atomizing nozzle can be evenly settled.

[0004] Existing PC board cutting devices require multiple adjustments to the board position using a fixed-angle cutting head when actually cutting PC boards with complex shapes. This is not only inefficient but also prone to errors due to repeated positioning. Furthermore, the laser cutting head is easily damaged when it collides with the PC board during the cutting process. Therefore, a PC board cutting device with angle adjustment function is designed. Utility Model Content

[0005] In view of the defects or deficiencies of existing PC board cutting devices, the purpose of this utility model is to provide a PC board cutting device with angle adjustment function, which not only facilitates the adjustment of the angle of the laser cutting head according to design requirements, but also effectively protects the laser cutting head.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solution:

[0007] This utility model provides a PC board cutting device with angle adjustment function, including a frame, an X-axis linear motor module on the frame, a connecting frame on the X-axis linear motor module, a Z-axis linear motor module on the connecting frame, a Y-axis linear motor module on the Z-axis linear motor module, and a six-axis robot on the Y-axis linear motor module. The six-axis robot is connected to a laser cutting head through a protective mechanism.

[0008] The protective mechanism is provided with a second connecting plate. A protrusion is provided on one outer wall of the second connecting plate. Both sides of the protrusion are connected to a pressure detection sensor through a damping cylinder. The pressure detection sensor is located at the top and bottom of the inner side of the first connecting plate. A spring is sleeved on the outer side of the outer wall of the damping cylinder.

[0009] Preferably, the spring is located between the surface of the protrusion and the pressure sensor.

[0010] Preferably, through holes are provided at the four corners of the protrusion surface, and guide rods are provided in the through holes. The two ends of the guide rods are respectively installed at the top and bottom of the inner side of the first connecting plate, and the outer wall of the guide rods and the hole wall of the through holes are in clearance fit.

[0011] Preferably, the second connecting plate is connected to the laser cutting head by fastening bolts.

[0012] Preferably, a connecting rod is provided on one outer wall of the first connecting plate, and the connecting rod is fixedly connected to one end of the six-axis robot by fastening bolts.

[0013] Preferably, a control box is provided on the frame, and the control box contains an A / D conversion module and a microcontroller.

[0014] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects:

[0015] 1. In this utility model, through a series of coordinated structural arrangements, when the equipment performs a cutting operation on the PC board placed on the top of the frame, the starting of the X-axis linear motor module, the Z-axis linear motor module, and the Y-axis linear motor module can respectively adjust the position of the laser cutting head on the X-axis, Y-axis, and Z-axis. The starting of the six-axis robot can adjust the angle of the laser cutting head. Thus, this utility model facilitates the adjustment of the angle of the laser cutting head according to design requirements. Whether it is acute angle, obtuse angle, or curved cutting, it can be completed in one go, greatly improving the cutting accuracy, reducing processing time, and improving production efficiency.

[0016] 2. In this utility model, through a series of coordinated structural arrangements, when the laser cutting head collides with the PC board during the cutting process, the damping cylinder, spring, and other structures can buffer the laser cutting head, reducing the impact force on the laser cutting head and preventing damage caused by excessive impact force. Furthermore, during the buffering process, the spring exerts a certain force on the pressure sensor. When the pressure data value detected by the pressure sensor exceeds the preset pressure data value range, the microcontroller controls the device to stop, preventing the impact force between the laser cutting head and the PC board from continuing to increase, further preventing damage to the laser cutting head due to excessive impact force. Therefore, this utility model effectively protects the laser cutting head. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] It should be noted that the following detailed description is exemplary and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0034] like Figure 1-4 As shown, a PC board cutting device with angle adjustment function includes a frame 800. An X-axis linear motor module 100 is mounted on the frame 800, which can indirectly drive a laser cutting head 600 to move in the X-axis direction. A connecting frame 700 is mounted on the X-axis linear motor module 100, and a Z-axis linear motor module 200 is mounted on the connecting frame 700. The Z-axis linear motor module 200 can indirectly drive the laser cutting head 600 to move in the Z-axis direction. A Y-axis linear motor module 300 is mounted on the Z-axis linear motor module 200, which can indirectly drive the laser cutting head 600 to move in the Y-axis direction. A six-axis robot 400 is mounted on the Y-axis linear motor module 300, and the six-axis robot 400 is connected to the laser cutting head 600 through a protective mechanism 500.

[0035] The protective mechanism 500 is provided with a second connecting plate 530. A protrusion 531 is provided on one outer wall of the second connecting plate 530. Both sides of the protrusion 531 are connected to the pressure detection sensor 560 through a damping cylinder 540. The pressure detection sensor 560 is located at the top and bottom of the inner side of the first connecting plate 510. A spring 520 is sleeved on the outer side of the outer wall of the damping cylinder 540. The pressure detection sensor 560 is a SALC300K piezoelectric sensor.

[0036] Spring 520 is located between the surface of protrusion 531 and pressure sensor 560.

[0037] Through holes are provided at the four corners of the surface of the protrusion 531. Guide rods 550 are installed in the through holes. The two ends of the guide rods 550 are respectively installed at the top and bottom of the inner side of the first connecting plate 510. The outer wall of the guide rods 550 and the hole wall of the through holes are in clearance fit. Because the outer wall of the guide rods 550 and the hole wall of the through holes are in clearance fit, the movement of the protrusion 531 can be limited and guided.

[0038] The second connecting plate 530 is connected to the laser cutting head 600 by fastening bolts.

[0039] A connecting rod 511 is provided on one outer wall of the first connecting plate 510. The connecting rod 511 is fixedly connected to one end of the six-axis robot 400 by fastening bolts.

[0040] A control box is installed on the frame 800. The control box contains an A / D conversion module and a microcontroller. The A / D conversion module is an ADS1115 A / D conversion module, and the microcontroller is an AT89C51 microcontroller. The output terminal of the pressure detection sensor 560 is electrically connected to the input terminal of the A / D conversion module, and the output terminal of the A / D conversion module is electrically connected to the input terminal of the microcontroller. The output terminal of the microcontroller is electrically connected to the input terminals of the X-axis linear motor module 100, the Z-axis linear motor module 200, the Y-axis linear motor module 300, and the six-axis robot 400, respectively.

[0041] Working Principle: When in use, with external power connected, the X-axis linear motor module 100, Z-axis linear motor module 200, and Y-axis linear motor module 300 adjust the position of the laser cutting head 600 along the X, Y, and Z axes, respectively, while the six-axis robotic arm 400 adjusts the angle of the laser cutting head 600. This allows for easy adjustment of the laser cutting head 600's angle according to design requirements, enabling seamless cutting of acute, obtuse, and curved angles, significantly improving cutting accuracy, reducing processing time, and increasing production efficiency. When the laser cutting head 600 collides with the PC board during cutting, the damping cylinder 540 and spring 520, among other components, prevent collisions. The cutting head 600 acts as a buffer, reducing the impact force on the laser cutting head 600 and preventing damage caused by excessive impact force. During the buffering process, the spring 520 exerts a certain force on the pressure sensor 560. When the pressure data value detected by the pressure sensor 560 exceeds the preset pressure data value range, the microcontroller controls the device to stop, preventing the impact force between the laser cutting head 600 and the PC board from increasing further, thus further preventing damage to the laser cutting head 600 due to excessive impact force. Therefore, this invention effectively protects the laser cutting head 600.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the invention. For those skilled in the art, various modifications and variations can be made to this invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this invention should be included within the protection scope of this invention.
