Description
Technical Field
[0001] This utility model relates to the field of circuit board manufacturing equipment technology, and in particular to a circuit board metal cover correction device. Background Technology
[0002] In circuit board manufacturing, metal covers (such as shielding covers) are used to protect electronic components. However, metal covers are easily deformed by external forces during transportation or assembly, resulting in poor adhesion to the circuit board and affecting performance. Traditional calibration methods usually rely on manual adjustment, which suffers from low efficiency, poor accuracy, and the risk of secondary damage. While some automated calibration equipment can replace manual labor, it still has the following drawbacks: First, the calibration pressure control is inaccurate, and pressure cannot be monitored in real time, making it easy for excessive force to cause further deformation of the metal cover; second, it has poor versatility, requiring the replacement of the entire fixture for different specifications of metal covers, resulting in high costs and cumbersome operation; finally, the calibration uniformity is insufficient, with a single pressure head design that makes it difficult to apply balanced pressure in different deformation directions.
[0003] Therefore, in view of the shortcomings of the existing technology, it is necessary to design a circuit board metal cover correction device to solve the above problems.
[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art.

[0037] Example:
[0038] like Figure 1 , Figure 2 and Figure 3As shown, this utility model discloses a circuit board metal cover correction device, including a workbench 100, which serves as the foundation of the entire device and provides a stable support platform. A correction fixture 1 is provided above the workbench 100, and a pressure sensor 3 is provided between the correction fixture 1 and the workbench 100 to monitor the correction pressure in real time, ensuring that the pressure during the correction process is controlled within a reasonable range to avoid overload damage. At least two guide rods 2 are provided vertically at the lower end of the correction fixture 1, with the lower ends of the guide rods 2 passing through and slidably connected to the workbench 100 to ensure the vertical stability of the correction fixture 1. A placement groove 11 for placing the metal cover is provided at the upper end of the correction fixture 1, and a correction platform 12 matching the shape of the inner cavity of the metal cover is provided within the placement groove 11 to provide bottom support for the metal cover and ensure correction accuracy. A correction pressure block 4 is provided above the correction platform 12, and the bottom of the correction pressure block 4 consists of a pressure head array composed of multiple pressure heads 41. The two sets of opposite sides of the calibration fixture 12 are respectively set in the vertical cross direction to ensure that the metal cover is subjected to uniform force; the front end of the pressure head 41 is provided with an elastic buffer to avoid scratching the surface of the metal cover; the calibration pressure block 4 is connected to the lifting mechanism 5, which is fixedly installed on the worktable 100. The lifting mechanism 5 is a servo motor driven screw lifting mechanism to ensure the accuracy of the vertical movement distance of the calibration pressure block; the pressure sensor 3 is electrically connected to the external control system to provide real-time feedback on the pressure data of the calibration fixture 1 and control the start and stop of the lifting mechanism 5.
[0039] The method and principle of this utility model are as follows: In use, the metal cover to be calibrated is placed in the placement slot 11 and fastened to the calibration platform 12. The lifting mechanism 5 is started, and the servo motor drives the lead screw to press down the calibration pressure block 4. The pressure head 41 contacts the surface of the metal cover and presses down to calibrate. During this process, the elastic buffer sheet at the front end of the pressure head 41 protects the metal cover from being damaged. At the same time, since the two sets of opposite sides of the pressure head 41 and the calibration platform 12 are correspondingly set, part of the pressure head 41 is aligned with the calibration platform 12, and part of it is on the outside of the calibration platform 12. During the pressing process, the pressure head 41 squeezes the side of the metal cover towards the calibration platform 12, so that the metal cover is completely in contact with the calibration platform 12 in both the horizontal and vertical directions during calibration, thus improving the calibration accuracy. The pressure sensor 3 monitors the pressure data in real time. When the pressure reaches the preset threshold, the control system stops the lifting mechanism 5 and maintains the pressure to keep the calibration accuracy of the metal cover stable. After calibration, the lifting mechanism 5 is reset and the metal cover is removed.
[0040] like Figure 1 , Figure 2 and Figure 3 As shown, there are four guide rods 2, which are symmetrically distributed at the four corners of the lower end of the correction fixture 1, further enhancing the stability and accuracy of the movement.
[0041] like Figure 1 , Figure 2 and Figure 3 As shown, the elastic buffer sheet of the pressure head 41 is made of rubber or silicone to avoid scratching the metal cover surface.
[0042] like Figure 1 , Figure 2 and Figure 3 As shown, the moving end of the lifting mechanism 5 is provided with a horizontal lifting plate 51, and the correction pressure block 4 is fixed at the lower end of the horizontal lifting plate 51. A linear bearing 52 is provided on the horizontal lifting plate 51 along the vertical direction. A guide column 6 is provided on the worktable 100 at the corresponding position of the linear bearing 52 along the vertical direction. The guide column 6 passes through the linear bearing 52 and slides with it to further ensure the accuracy of the vertical movement direction of the correction pressure block.
[0043] like Figure 1 , Figure 2 and Figure 3 As shown, the mounting slot 11 and the calibration block 4 are detachably connected to the calibration platform 12 and the horizontal lifting plate 51 via magnetic quick-change interfaces. Before use, for different specifications of metal covers, select the appropriate model of calibration platform 12 and pressure block 4 and install them on the calibration device for easy replacement and maintenance.
[0044] like Figure 1 , Figure 2 and Figure 3 As shown, the pressure sensor is a capacitive pressure sensor, which increases the displacement during measurement and provides a buffer for pressure calibration with a metal cover.
[0045] like Figure 1 , Figure 2 and Figure 3 As shown, a limiting block 13 is provided on the side of the mounting groove 11 to prevent the metal cover from shifting during the calibration process and to ensure calibration accuracy.
[0046] like Figure 1 , Figure 2 and Figure 3 As shown, the calibration platform 12 has a built-in heating element and temperature sensor, which can locally heat the metal cover, making it suitable for metal covers that require thermal calibration and further improving the calibration effect.
[0047] The circuit board metal cover correction device provided by this utility model has multiple advantages such as high precision, intelligence, stability, high efficiency, process adaptability, safety, economy and easy operation. It is suitable for the correction needs of various precision metal parts, and performs particularly well in high-precision, multi-variety and flexible production environments.
[0048] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
