Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4, the punching device for the new energy vehicle-mounted power supply PCB board in this embodiment includes a workbench 1. A horizontally arranged top plate 2 and a bottom plate 3 are respectively fixed on the upper and lower sides of the workbench 1 through brackets. A CCD punching machine 4 for punching the PCB board is arranged between the workbench 1 and the top plate 2. An auxiliary mechanism 5 for facilitating the punching of the PCB board and simultaneously driving the linear movement of the CCD punching machine 4 is arranged on the upper side of the top plate 2. A dust suction mechanism 6 is arranged on the upper side of the bottom plate 3. A CCD lens 7 is fixed on the CCD punching machine 4;

[0021] It should be noted that the CCD punching machine 4 is the core component of the device and is installed between the workbench 1 and the top plate 2. The CCD punching machine 4 uses the CCD lens 7 to identify the target on the PCB board to ensure the accuracy of punching. The CCD punching machine 4 can perform linear movement under the drive of the auxiliary mechanism 5 to meet the punching requirements at different positions.

[0022] The auxiliary mechanism 5 includes an electric push rod 51, a movable plate 52, a positioning rod 53, a threaded rod 54, a driving motor 55, two movable pieces 56, a connecting ring 57 and a blocking cloth sleeve 58. The electric push rod 51 is fixed at the center of the upper surface of the top plate 2. The movable plate 52 is horizontally fixed at the bottom end of the output shaft of the electric push rod 51. The positioning rod 53 and the threaded rod 54 are symmetrically arranged on the left and right sides between the opposite sides of the top plate 2 and the workbench 1. The positioning rod 53 is fixed at the left side between the opposite sides of the top plate 2 and the workbench 1, and the threaded rod 54 is rotatably connected through a bearing at the right side between the opposite sides of the top plate 2 and the workbench 1. The two movable pieces 56 are respectively movably arranged outside the positioning rod 53 and the threaded rod 54. The left movable piece 56 is slidably connected to the positioning rod 53, and the right movable piece 56 is threadedly connected to the threaded rod 54.

An annular structure of light strip 59 is fixed on the lower surface of the movable plate 52.

[0023] It should be noted that there are two movable pieces 56, which are respectively arranged outside the positioning rod 53 and the threaded rod 54. The left movable piece 56 is slidably connected to the positioning rod 53, and the right movable piece 56 is threadedly connected to the threaded rod 54. The function of the movable piece 56 is to connect the positioning rod 53 and the threaded rod 54, transmit power, and support the PCB board at the same time.

[0024] Further, the auxiliary mechanism 5 further includes a support assembly for supporting the PCB board. The support assembly includes a support base 501 fixed to the upper surface of the workbench 1. The upper surface of the support base 501 is concave and extends downward to form a support opening. A placement tray 502 is movably connected between the inner walls on the four sides of the support opening. Four springs 503 are fixed to the lower surface of the placement tray 502. A sliding rod 504 that is limited and slides with the workbench 1 is vertically fixed to the lower surface of the placement tray 502 and inside the spring 503. Four positioning pieces 505 are rotatably connected to the upper surface of the placement tray 502 through a rotating rod.

[0025] It should be noted that the springs 503 are fixed to the lower surface of the placement tray 502 and there are four of them, which are used to provide necessary elastic support to ensure the stability of the PCB board during the punching process. The springs 503 also help to absorb the impact force generated during punching and reduce the damage to the PCB board.

[0026] Further, the inner diameter of the connecting ring 57 is adapted to the outer diameter of the support base 501. The shape of the support base 501 is a cylinder, and the cross-sectional shape of the support opening on its upper side is a circle.

[0027] Further, plate openings are provided on both the left and right sides of the upper surface of the movable plate 52, and both the movable piece 56 and the threaded rod 54 are located inside the plate openings and do not contact each other.

[0028] Moreover, these design features work together to improve the operation accuracy and stability of the PCB board punching device. At the same time, the structural design of the device is optimized to make it more suitable for precise industrial applications. Through the optimization of these details, the device can more effectively support and position the PCB board, ensure the accuracy and repeatability of the punching process, thereby improving the quality of the final product. At the same time, a solder mask opening is designed at the target position.

[0029] Further, the dust suction mechanism 6 includes a dust suction box 61 fixed to the upper surface of the bottom plate 3. Three dust collection pipes 62 are connected and fixed to the upper surface of the dust suction box 61. A filter screen 63 is fixed between the inner walls on the four sides of the dust suction box 61. The other end of the dust collection pipe 62 is fixed to the back of the support base 501 and is communicated with the support opening.

[0030] Further, the cloth cover 58 is a polyester fiber light-shielding cover.

[0031] The polyester fiber light-shielding cover of the cloth cover 58 is a specific design feature, which has the following functions and advantages:

[0032] Light-shielding performance: Polyester fiber materials usually have good light-shielding performance, which is especially important for the CCD punching machine 4 during high-precision punching operations. The light-shielding cover can prevent external light from interfering with the imaging of the CCD lens 7, ensuring that the punching machine can accurately identify the targets on the PCB board.

[0033] Protective function: The light-shielding cover can protect the CCD lens 7 from dust, debris, or other contaminants that may be generated during the punching process. This helps to maintain the cleanliness of the CCD lens 7 and ensure its long-term stable operation.

[0034] Reducing reflection: During the punching process, reflection may occur on the surface of the PCB board, which may interfere with the recognition of the CCD lens 7. The polyester fiber light-shielding cover can reduce this reflection and improve the recognition accuracy of the punching machine.

[0035] Durability: Polyester fiber is a durable material that can withstand the wear and tear during the punching process and repeated use, thus extending the service life of the light-shielding cover.

[0036] In summary, the polyester fiber light-shielding cover of the baffle cloth cover 58 is an important component designed to improve the punching accuracy and protect the CCD punching machine 4. By providing a stable light-shielding environment, it helps to ensure the high efficiency and high precision of the PCB board punching process.

[0037] The working principle of the above embodiments is as follows:

[0038] During the punching process, place the PCB board on the pallet 502 in the support base 501, and use the rotation of the positioning piece 505 to position the PCB board. After the PCB board is fixed and punched by the CCD punching machine 4, through the positioning cooperation of the spring 503 and the slide bar 504 with the workbench 1, to avoid excessive rigid force during the punching process. During the operation of the electric push rod 51, it drives the movable plate 52 to move downward. After the CCD punching machine 4 reaches the designated position, the driving motor 55 runs. When its output shaft rotates, it drives the threaded rod 54 to rotate, further driving the movable piece 56 to drive the connecting ring 57 to move upward. At this time, the baffle cloth cover 58 rises, folds the punching space. At this time, with the action of the light belt 59, the brightness of the punching space is increased, further improving the shooting effect of the CCD lens 7. At the same time, it can effectively prevent the punching dust from overflowing. The dust in the support base 501 and the baffle cloth cover 58 can be extracted by the exhaust fan 64. The dust enters the dust collection box 61 through the dust collection pipe 62, and then is filtered through the filter screen 63 and discharged, facilitating the subsequent cleaning of the dust.
