Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.
[0027] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0028] like Figures 1 to 5 As shown, this application provides a circuit board grinding machine, including: a machine body 100, including a support table 10, a gantry frame 20, an X-axis moving module 30, a Y-axis moving module 40, a Z-axis moving module 50, a grinding motor 60, and a placement table 70. The X-axis moving module 30 is located at the upper end of the gantry frame 20, the Y-axis moving module 40 is located at the output end of the X-axis moving module 30, the Z-axis moving module 50 is located at the output end of the Y-axis moving module 40, the grinding motor 60 is located at the output end of the Z-axis moving module 50, and a brush roller 61 is connected to the output end of the grinding motor 60; a clamping and positioning assembly 80 is located at the upper end of the placement table 70, and the clamping and positioning assembly 80 includes an auxiliary external component fixed to the upper end of the placement table 70. A first cylinder 82 and a second cylinder 85 are installed on the outer side of the auxiliary outer rail 81. The output end of the first cylinder 82 is provided with a first pressure sensor 83 and a first clamping plate 84. The output end of the second cylinder 85 is provided with a second pressure sensor 86 and a second clamping plate 87. A debris suction assembly 90 is located between the support platform 10 and the placement platform 70. The debris suction assembly 90 includes a suction box 92 installed at the bottom of the support platform 10. A suction motor 93 is installed on the outer side of the suction box 92. A drive shaft 94 is provided at the output end of the suction motor 93. A fan blade 95 is provided on the outer side of the drive shaft 94. A landslide hopper 97 is provided at the bottom of the placement platform 70. An air inlet pipe 96 connects the landslide hopper 97 and the suction box 92.
[0029] After adopting the above technical solution, since the clamping and positioning component 80 is located at the upper end of the placement platform 70, when the clamping and positioning component 80 needs to clamp the PCB board, it is inserted into the corner of the auxiliary outer frame 81. The control panel 11 controls the output end of the first cylinder 82 to drive the first pressure sensor 83 and the first clamping plate 84 to clamp it laterally. The first pressure sensor 83 detects the clamping force. After reaching the set range value, the operation of the output end of the first cylinder 82 is stopped. Similarly, the control panel 11 controls the output end of the second cylinder 85 to drive the second pressure sensor 86 and the second clamping plate 87 to clamp it longitudinally. The second pressure sensor 86 detects the clamping force. After reaching the set range value, the operation of the output end of the second cylinder 85 is stopped, thereby automatically clamping the PCB board. The force can be freely adjusted through the control panel 11.
[0030] It should be noted that when grinding the PCB board, it is placed on the upper end of the placement stage 70 and clamped by the clamping and positioning component 80. Then, the output end of the X-axis moving module 30 drives the Y-axis moving module 40, Z-axis moving module 50, grinding motor 60 and brush roller 61 to make lateral adjustments. Next, the output end of the Y-axis moving module 40 is controlled to drive the Z-axis moving module 50, grinding motor 60 and brush roller 61 to make longitudinal adjustments. Finally, the Z-axis moving module 50 controls the grinding motor 60 and brush roller 61 to make height adjustments. The grinding motor 60 is started, and the output end of the grinding motor 60 drives the brush roller 61 to perform grinding operations along the outer side of the PCB board, thereby meeting the grinding requirements.
[0031] Since the debris suction assembly 90 is located between the support platform 10 and the placement platform 70, metal debris will splash during the grinding process of the brush roller 61 on the PCB board. The suction motor 93 is started in advance via the control panel 11, so that the output end of the suction motor 93 drives the drive shaft 94 and the fan blade 95 to rotate at high speed. Since the air inlet pipe 96 is connected to the slide bucket 97, the top of the slide bucket 97 will suck the debris into the interior of the slide bucket 97 through the through hole. Then, it slides down the inner wall of the slide bucket 97 into the interior of the debris collection box 91. At the same time, with the filtration of the filter plate 98, the debris is prevented from entering the interior of the suction box 92 along the air inlet pipe 96. Finally, the gas is discharged from the air outlet pipe 99, thus completing the collection of debris and preventing debris from splashing and falling on the upper part of the support platform 10.
[0032] In an optional embodiment, the gantry 20 and the support platform 10 are fixedly connected, the X-axis moving module 30 is connected to the gantry 20 by bolts, the Y-axis moving module 40 is connected to the output end of the X-axis moving module 30 by bolts, the Z-axis moving module 50 is connected to the output end of the Y-axis moving module 40 by bolts, and the grinding motor 60 is connected to the output end of the Z-axis moving module 50 by bolts, thereby ensuring that the grinding motor 60 can be freely adjusted along the X, Y, and Z axes.
[0033] In one optional embodiment, the brush roller 61 is fixedly connected to the output end of the grinding motor 60. The brush roller 61 has a cylindrical structure and can perform grinding operations on the PCB board.
[0034] In an optional embodiment, the placement platform 70 and the support platform 10 are connected by bolts. A mesh 71 is installed on the top of the placement platform 70, and several sets of through holes are opened in the middle of the mesh 71. During the process of the brush roller 61 grinding the PCB board, the debris can fall into the interior of the landslide hopper 97 along the through holes, which facilitates the collection of debris.
[0035] In an optional embodiment, the first cylinder 82 and the second cylinder 85 are both connected to the auxiliary outer frame 81 by bolts, the first pressure sensor 83 and the second pressure sensor 86 are both electrically connected to the control panel 11, the length of the first clamping plate 84 is greater than the length of the second clamping plate 87, and the PCB board can be automatically clamped in the horizontal and vertical directions. The clamping force is adjustable and no manual clamping and positioning is required.
[0036] In an optional embodiment, a debris collection box 91 is placed on the upper end of the support platform 10, and the debris collection box 91 is located at the bottom opening of the landslide bucket 97. The landslide bucket 97 is connected to the through hole, so that debris can slide along the inner wall of the landslide bucket 97 into the interior of the debris collection box 91 for unified collection.
[0037] In an optional embodiment, the suction motor 93 is electrically connected to the control panel 11, the output end of the suction motor 93 is fixedly connected to the drive shaft 94, and the fan blades 95 are fixedly connected to the drive shaft 94. The number of fan blades 95 is several groups and they are arranged in an array. The air inlet pipe 96 is connected to the suction box 92, which facilitates the flow of air. The airflow at the top of the strainer 71 can be drawn into the interior of the landslide hopper 97, thereby driving the collection of debris in the air.
[0038] In an optional embodiment, the air inlet pipe 96 is connected to the interior of the landslide bucket 97, and a filter plate 98 is installed at the end of the air inlet pipe 96 near the inner wall of the landslide bucket 97. An air outlet pipe 99 is provided on one side of the air suction box 92, and the air outlet pipe 99 is connected to the air suction box 92.
[0039] It should be noted that this ensures that the gas enters the air intake box 92 through the air inlet pipe 96 and is finally discharged through the air outlet pipe 99, thus completing the airflow. This allows the PCB board grinding debris to enter the landslide hopper 97 and the debris collection box 91 for collection.
