[0001] The utility model relates to the technical field of PCB board processing equipment, in particular to a measuring device for PCB board processing. Background Art

[0002] PCB board, Chinese name is printed circuit board, also known as printed circuit board or printed circuit board, is the support of electronic components and the provider of electrical connections for electronic components. Because it is made using electronic printing technology, it is called a "printed" circuit board. PCB board plays an important role in various electronic devices, such as providing mechanical support for the fixation and assembly of various electronic components such as integrated circuits, realizing the wiring and electrical connection or electrical insulation between various electronic components such as integrated circuits, and providing the required electrical characteristics, such as characteristic impedance, etc. PCB boards need to be measured during the processing to ensure production quality.

[0003] At present, the existing measuring devices usually clamp and position the two sides of the PCB board to ensure its fixing effect for easy measurement when measuring the PCB board. However, the existing measuring devices only clamp the two sides of the PCB board, which may cause the instrument to shake and vibrate when measuring the PCB board, resulting in one side tilting or shifting forward and backward. The personnel need to manually adjust the position of the PCB board, which makes the measurement step time-consuming and labor-intensive, and reduces the measurement efficiency and practicality of the measuring device. Therefore, we propose a measuring device for PCB board processing to solve the above problems. Utility Model Content

A clamping component connected to the two limiting blocks 6 is arranged at the bottom of the operating table 1. A measuring device 2 is fixedly installed on one side of the top of the operating table 1, and a supporting leg is arranged at the bottom of the operating table 1. Specifically, a person drives the two extrusions by operating the positioning component. The plate 10 positions the two sides of the top of the PCB board, and by operating the limit pad 9 in the clamping box 8, it is placed in the adjacent matching connection groove, and cooperates with the inner wall of one side of the clamping box 8 to limit one side of the PCB board. By starting the clamping assembly, the two clamping boxes 8 are driven to move closer to each other, thereby achieving the clamping and limiting of the other two sides of the PCB board, thereby effectively positioning the PCB board, facilitating the measuring equipment 2 to perform measurement operations, and improving the practicality of the measuring device. The measuring equipment 2 is a device for measuring the thickness, length, etc. of the PCB board, which is a prior art, and is connected to the motor 3 through an external controller and a power supply, which is a prior art and will not be described here.

[0025] Furthermore, a plurality of connecting grooves are provided in a linear array on the other side of the top of the two clamping boxes 8, a limiting pad 9 is arranged inside the clamping box 8, and the limiting pad 9 is matched with the adjacent connecting grooves, and a soft pad is fixedly installed on one side of the limiting pad 9 and the inner wall of one side of the clamping box 8.

The soft pad can increase the softness and avoid the limiting pad 9 and the inner wall of one side of the adjacent clamping box 8 from wearing the outside of the PCB board.

[0026] Furthermore, the positioning component includes a mounting shell 11 arranged on one side of the top of the clamping box 8, the bottom of the mounting shell 11 is open, and the bottom surface of the mounting shell 11 is fixedly installed on one side of the top of the clamping box 8, a limiting plate 13 is provided inside the mounting shell 11, a pull rod 12 is sleeved inside the limiting plate 13, and a top end of the pull rod 12 passes through the top of the mounting shell 11 and is fixedly installed with a pull block.

At this time, the personnel can place the PCB board in the clamping box 8, and then release the pulling block to make the spring 14 lose the squeezing force and push the limiting plate 13 back to its original position under elastic recovery. The limiting plate 13 then drives the pull rod 12 to return and the squeezing plate 10 at its bottom to return to squeeze the top of the PCB board, so as to position the top of the PCB board and avoid the situation that the PCB board is tilted during the measurement and clamping process and affects the measurement.

[0028] Furthermore, the clamping assembly includes a motor 3 arranged at the bottom of the operating table 1, and both sides of the motor 3 are fixedly installed with the bottom of the operating table 1 through a bracket.

[0029] Furthermore, there are four supporting legs, and the tops of the four supporting legs are fixedly connected to the four corners of the bottom of the operating table 1. Specifically, through the setting of the supporting legs, the four supporting legs can firmly support the operating table 1 and improve the overall stability of the entire measuring device.

[0030] In summary:

[0032] By holding the pulling block and pulling the pulling rod 12 to move upward, the pulling rod 12 then drives the limiting plate 13 in the mounting shell 11 and the squeezing plate 10 at the bottom to move upward, and the limiting plate 13 then squeezes the spring 14. When the PCB board is placed in the clamping box 8, the pulling block is released to make the spring 14 lose its squeezing force and push the limiting plate 13 back to its position due to elastic recovery. The limiting plate 13 then drives the pulling rod 12 back to its position and the squeezing plate 10 at its bottom to squeeze the top of the PCB board, thereby positioning the top of the PCB board, avoiding the situation where the PCB board is lifted up during the measurement and clamping process and affecting the measurement, and effectively positioning the PCB board in an all-round way without the need for manual adjustment by personnel, thereby improving the stability of the device during measurement.
