Specific implementation mode

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0017] Please refer to Figures 1-3 , the present invention provides a technical solution: a surface engraving device for the production of energy storage circuit boards, including a base 1, an engraving machine 2 for engraving energy storage circuit boards is installed on one side of the base 1, a limiting groove 3 for placing energy storage circuit boards is arranged in the middle of the upper surface of the base 1, a vacuum chuck 4 for positioning small circuit boards and a fine-tuning structure 5 for driving the vacuum chuck 4 to drive the small circuit board to finely adjust the angle are arranged in the limiting groove 3, and an auxiliary adjustment assembly 6 is arranged above the base 1; The fine-tuning structure 5 includes a rotating block 501 and a driving motor 502. The vacuum chuck 4 is fixed in the middle of the rotating block 501. An installation structure 7 for the rotating block 501 to rotate is arranged at the bottom of the base 1. A transmission structure 8 is arranged between the rotating block 501 and the driving motor 502.

[0018] By fixedly connecting the vacuum chuck 4 with the rotating block 501, when the rotating block 501 rotates, the vacuum chuck 4 rotates synchronously, and the small or special-shaped circuit board adsorbed on the surface of the vacuum chuck 4 adjusts the angle accordingly. Align the edge or hole position of the circuit board with the engraving path.

[0019] The transmission structure 8 includes a driving gear 801. The connecting plate 802 is fixed on the lower surface of the base 1 by screws. The driving motor 502 is fixed on one side of the connecting plate 802 by screws. The driving gear 801 is fixed on the output end of the driving motor 502. Teeth 803 are arranged on the outside of the rotating block 501, and the driving gear 801 meshes with the teeth 803.

[0020] The drive motor 502 meshes with the teeth 803 outside the rotating block 501 through the drive gear 801 at the output end to form a gear transmission system. When the drive motor 502 starts, the drive gear 801 rotates and drives the rotating block 501 to rotate by a small angle around the bearing axis.

[0021] The auxiliary adjustment assembly 6 includes a moving truss 601 which is arranged in a portal shape. A longitudinal electric slide 602 is installed on the lower surface of the moving truss 601, and a material sensor 603 is fixed on the slide of the longitudinal electric slide 602 by screws. The material sensor 603 adopts the Keyence LK-H series laser profile sensor, which can detect the position and profile of the circuit board in a non-contact manner.

[0022] There are two sets of the longitudinal electric slide 602 and the material sensor 603 at the bottom of the moving truss 601, and the material sensor 603 is located above the limit slot 3.

[0023] There are two sets of the moving truss 601. At both ends of each set of the moving truss 601, there is a set of transverse electric slides 604 for the horizontal movement of the moving truss 601, and the transverse electric slides 604 are installed on both sides of the base 1 by screws.

[0024] The two portal-shaped moving trusses 601 move horizontally on both sides of the base 1 through the transverse electric slides 604 to cover the full width of the engraving area; the longitudinal electric slide 602 at the bottom of each moving truss 601 drives the material sensor 603 to move along the Y-axis, and the two material sensors 603 cooperate to scan the position of the circuit board in the limit slot 3.

[0025] The data of the material sensor 603 is fed back to the control system of the engraving machine 2, triggering the vacuum chuck 4 to adsorb and position and the fine-tuning structure 5 to act. The positioning method and the control system of this auxiliary adjustment assembly 6 are mature technologies in the prior art and will not be elaborated here.

[0026] The installation structure 7 includes a relief groove 701 which is opened in the middle of the base 1. A connecting ring 702 is installed on the lower surface of the base 1 by screws, and the rotating block 501 is rotatably connected in the connecting ring 702 through a bearing.

[0027] The relief groove 701 in the middle of the base 1 provides a rotating space for the rotating block 501. The connecting ring 702 is fixed on the bottom surface of the base 1 by screws, and the internal bearing supports the rotating block 501 to achieve low-resistance rotation. The suction pipe 703 of the vacuum chuck 4 is connected to an external air source through a rotary joint. The rotary joint allows the pipe 703 to maintain airtightness when the chuck rotates, and ensures that there is no risk of entanglement of the pipe 703 during the rotation process, maintaining a stable negative pressure adsorption.

[0028] The suction end of the vacuum suction cup 4 is connected to a pipeline 703 through a rotary joint. A through groove 704 for the pipeline 703 to penetrate is provided in the middle of the rotating block 501.

[0029] During use, the other end of the pipeline 703 is connected to a vacuum pump. The rotary joint and the vacuum pipeline 703 are connected by a 316L stainless steel bellows. A stable vacuum degree of -90 kPa is still maintained under the condition of continuous rotation of the rotating block 501. The rotating block 501 supported by bearings is matched with a gear ring drive, with a module of 0.5 and a backlash ≤ 0.03 mm.

[0030] During use, the small circuit board is placed in the middle of the base 1. The vacuum suction cup 4 adsorbs the small circuit board through the external connection pipeline 703 and the vacuum pump. Two sets of gantry moving trusses 601 horizontally move on both sides of the base 1 through a transverse electric slide 604, covering the full width of the engraving area; the longitudinal electric slide 602 at the bottom of each moving truss 601 drives the material sensor 603 to move along the Y-axis. The double material sensors 603 cooperate to scan the position of the circuit board in the limit groove 3 and feedback the data to the control system of the engraving machine 2. The driving motor 502 finely adjusts the angle of the rotating block 501 through gear transmission, aligning the board features with the preset engraving path. Specifically: the driving motor 502 starts, drives the driving gear 801 to rotate and drives the rotating block 501 to rotate by a small angle around the bearing axis, aligning the board features with the preset engraving path, and the engraving machine 2 performs engraving work.

[0031] Among them, the driving motor 502 adopts the model 42HS03, with a module of 0.5 and a backlash ≤ 0.03 mm, which can meet the angle adjustment requirement of ±0.1°.

[0032] Compared with the traditional limiting method of the strip contacting and pressing against the edge of the circuit board, this positioning device can be applied to small or special-shaped circuit boards, enabling this engraving device to be applicable to the engraving of circuit boards of different sizes and shapes.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
