Description

Technical Field

[0002] In the manufacturing process of security cameras, aluminum-based circuit boards are widely used in the circuit systems of security cameras due to their good heat dissipation performance, mechanical strength and electrical insulation. Drilling, as one of the key processes in the production of aluminum-based circuit boards, directly affects the quality of the circuit boards and the compatibility of subsequent component installation, and places high demands on the precision, efficiency and ease of operation of the drilling device.

[0003] Currently, some drilling devices on the market typically require various fixing tools, such as clamps and bolts, to cumbersomely secure aluminum-based circuit boards before drilling them. During this process, operators need to repeatedly adjust the position and tightness of the fixing tools to ensure that the circuit board does not shift during drilling. If the aluminum-based circuit board shifts during drilling, it will lead to problems such as drilling position deviation and non-compliant hole diameter, seriously affecting drilling accuracy and circuit board quality. However, this method of fixing, which relies on multiple fixing tools and is complex to operate, not only consumes a lot of manpower and time costs, increases the complexity of the production process, and reduces production efficiency, but also, in actual production, the frequent fixing operations can easily damage the surface of the aluminum-based circuit board, further affecting product quality and hindering the efficient and high-quality production of aluminum-based circuit boards for security cameras.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example

[0023] like Figures 1-6 As shown, the device includes a housing 1, with a mounting plate 2 fixedly connected to one side of the housing 1. The mounting plate 2 is L-shaped, and an electric telescopic rod 4 is mounted on the top of the mounting plate 2. The telescopic end of the electric telescopic rod 4 passes through the mounting plate 2 and is movably connected to it. A lifting plate 3 is fixedly connected to the telescopic end of the electric telescopic rod 4. A motor 5 is mounted on the bottom of the lifting plate 3, and a drill bit 6 is mounted on the output end of the motor 5. A pressing mechanism is provided at the bottom of the lifting plate 3. The pressing mechanism is used to fix the aluminum-based circuit board when drilling. A center positioning mechanism is provided inside the housing 1. The center positioning mechanism is used to quickly position the aluminum-based circuit board at the center of the top of the housing 1. A second circular opening 10 is provided on the top of the housing 1, and the second circular opening 10 corresponds to the first circular opening 9.

[0024] The electric telescopic pole 4 and motor 5 in this technical solution are common driving devices on the market. Their working principle and practical method are common knowledge among people in this field, so they will not be described in detail in this technical solution.

[0025] like Figures 1-6 As shown, the pressing mechanism includes a fixed plate 7. A fixed plate 7 is provided below the lifting plate 3. A first circular opening 9 is provided at the top of the fixed plate 7 near the center. T-shaped rods 21 are provided at the four corners above the lifting plate 3. The bottom end of the T-shaped rod 21 passes through the lifting plate 3 and is movably connected to the lifting plate 3. The bottom end of the T-shaped rod 21 is fixedly connected to the top of the fixed plate 7. A first spring 8 is sleeved on the side wall of the T-shaped rod 21. One end of the first spring 8 is fixedly connected to the lifting plate 3, and the other end is fixedly connected to the fixed plate 7. Several evenly distributed anti-slip rubber balls 12 are fixedly connected to the bottom of the fixed plate 7. The bottom of the anti-slip rubber balls 12 is arc-shaped.

[0026] When the lifting plate 3 and the motor 5 descend simultaneously via the pressing mechanism, the anti-slip rubber balls 12 on the fixing plate 7 can preferentially contact the aluminum-based circuit board and press and fix it, so that the aluminum-based circuit board will not vibrate or shift during the drilling process. The anti-slip rubber balls 12 are made of rubber, which can deform to a certain extent and increase the friction during use, effectively improving the pressing and fixing effect of the aluminum-based circuit board, while also protecting the aluminum-based circuit board and preventing it from being damaged. Example

[0027] like Figures 3-6As shown, the positioning mechanism includes rectangular plates 14. Rectangular plates 14 are symmetrically arranged inside the housing 1. Screw holes 15 are respectively opened on the opposite sides of the two rectangular plates 14. A multi-directional screw 16 is installed between the two screw holes 15. The two ends of the multi-directional screw 16 pass through the housing 1 and are movably connected to the housing 1. A rocker arm 20 is fixedly connected to one end of the multi-directional screw 16. A movable opening 13 is symmetrically opened on the top of the housing 1. The top of the rectangular plates 14 extends into the movable opening 13. A clamping mechanism is respectively provided on the top of the two rectangular plates 14. The clamping mechanism includes a square hole 17. A square hole 17 is opened on the top of the rectangular plates 14. A second spring 18 is fixedly connected to the bottom of the inner cavity of the square hole 17. A rectangular block 19 is provided in the square hole 17. The top of the second spring 18 is fixedly connected to the bottom of the rectangular block 19. The top of the rectangular block 19 extends above the housing 1.

[0028] The positioning mechanism can improve the accuracy of drilling and prevent the anti-slip rubber balls 12 on the fixing plate 7 from shifting before contacting the aluminum-based circuit board. At the same time, it mainly plays the role of positioning the aluminum-based circuit board in the center position, which can effectively improve the convenience of use.

[0029] Among them, the top of the lifting plate 3 is symmetrically fixedly connected with the limiting plate 11. The top of the two limiting plates 11 respectively penetrates the mounting plate 2 and is movably connected to the mounting plate 2. The top of the limiting plate 11 extends above the mounting plate 2. The limiting plate 11 can limit the lifting plate 3, so that the electric telescopic rod 4 will not rotate when it extends.

[0030] Working Principle: In use, the aluminum-based circuit board to be processed is first placed at the top center of the housing 1, aligning the drilling positions with the drill bit 6. Next, the motor 5 is started via an external power supply, driving the drill bit 6 to rotate. Then, the electric telescopic rod 4 is controlled by an external power supply to lower the lifting plate 3, causing the motor 5 and the fixed plate 7 to descend. When the fixed plate 7 descends to a certain extent, the anti-slip rubber ball 12 makes initial contact with the aluminum-based circuit board. As the lifting plate 3 continues to descend, it presses against the aluminum-based circuit board, and the reaction force pushes the T-shaped rod 21 upwards and onto the first... When spring 8 is compressed, drill bit 6 continues to descend, thus securing the aluminum-based circuit board before drilling. Lifting plate 3 and drill bit 6 continue to descend to drill holes in the aluminum-based circuit board. After drilling, the electric telescopic rod 4 is controlled by the power supply to lift lifting plate 3 as a whole. Simultaneously, the first spring 8 pushes the anti-slip rubber ball 12 on the fixing plate 7 to maintain contact with the aluminum-based circuit board until drill bit 6 completely disengages from the aluminum-based circuit board and rises to a certain position. Then, T-shaped rod 21 descends its entire stroke, causing fixing plate 7 and anti-slip rubber ball 12 to disengage from the aluminum-based circuit board, thus completing the drilling operation.

[0031] To ensure drilling accuracy when needed, the aluminum-based circuit board to be processed can be fixed first. The aluminum-based circuit board is placed at the top center of the housing 1. Then, the multi-directional lead screw 16 is rotated by the rocker arm 20, causing the two rectangular plates 14 to move towards the center of the housing 1. This allows the rectangular blocks 19 on the two rectangular plates 14 to contact the sidewalls of the aluminum-based circuit board, thus clamping it. This provides initial fixation. Next, as the fixing plate 7 descends, the anti-slip rubber ball 12 preferentially contacts the aluminum-based circuit board and presses down on the rectangular blocks 19, causing the rectangular blocks 19 to descend and compress the second spring 18. This prevents displacement when fixing the aluminum-based circuit board, further improving accuracy.

[0032] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
