Multi-station PCB synchronous etching processing device

Abstract

This utility model belongs to the field of circuit board technology, and in particular to a multi-station PCB board synchronous etching processing device. It includes a base, with worktables fixedly connected to both sides of the upper surface of the base, and placement tables fixedly connected to the upper surfaces of the worktables. This utility model activates an electric push rod to drive one of the connecting blocks to slide, which in turn causes the I-shaped block to drive the slider to slide. The slider drives the connecting plate to move, causing the slide rod to slide against the inner wall of the worktable. This allows both connecting blocks to slide inward simultaneously, enabling the connecting blocks to drive the positioning plate to clamp and position the two sides of the PCB board. Then, a motor is activated to drive a gear to rotate, which drives two racks to move inward simultaneously, pulling the T-shaped block to slide. This allows the second connecting block to drive the positioning plate to clamp and position the other two sides of the PCB board. This achieves clamping and positioning of PCB boards of different sizes, preventing uneven spraying due to positional shifts during PCB board processing.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0020] Please see Figure 1-5In this implementation scheme: a multi-station PCB board synchronous etching processing device includes a base 1. Worktables 2 are fixedly connected to both sides of the upper surface of the base 1. Placement platforms 3 are fixedly connected to the upper surface of each worktable 2. Slider blocks 4 are slidably connected to the lower inner surfaces of both worktables 2. Through grooves 5 are formed on both the upper and lower sides of each slider 4. Connecting plates 6 are slidably connected to the inner walls of the through grooves 5. Sliding rods 7 are fixedly connected to the middle of the lower surface of each connecting plate 6. The outer walls of the sliding rods 7 are slidably connected to the lower inner surface of the worktables 2. I-beam blocks 8 are fixedly connected to the upper surfaces of both sliders 4. The outer walls of the I-beam blocks 8 are slidably connected to both sides of the surface of the worktables 2. Connecting block 9 is fixedly connected to the upper surface of 8. Electric push rod 10 is fixedly connected to one side of each of the two worktables 2. The output end of electric push rod 10 is fixedly connected to one side of one of the connecting blocks 9. Motor 11 is fixedly connected to the lower inner surface of the two worktables 2. Gear 12 is fixedly connected to the output end of motor 11. T-block 14 is slidably connected to the other two sides of the surface of worktable 2. Rack 13 is fixedly connected to one side of the lower surface of T-block 14. Rack 13 meshes with both sides of gear 12. Connecting block 25 is fixedly connected to the upper surface of T-block 14. Positioning plate 16 is fixedly connected to the upper surfaces of connecting block 9 and connecting block 25.

[0021] In this embodiment, the PCB board is placed on two placement platforms 3. Then, the electric push rod 10 is activated to drive one of the connecting blocks 9 to slide. The connecting block 9 drives the I-beam block 8 to slide, which in turn drives the slider 4 to slide. When the slider 4 moves, it drives the connecting plate 6 to slide within the through groove 5. When the connecting plate 6 moves, the sliding rod 7 on its lower surface slides on the inner wall of the worktable 2, thereby pulling all four sliders 4 to slide inward simultaneously. This, in turn, drives two I-beam blocks 8 to slide inward simultaneously, causing the connecting blocks 9 connected to them to slide inward simultaneously. The connecting block 9 can drive the positioning plate 16 to clamp and position the two sides of the PCB board. Then, the motor 11 is started to drive the gear 12 to rotate. The gear 12 drives the racks 13 on both sides to move inward at the same time. In turn, the racks 13 pull the T-shaped block 14 to move inward at the same time, which drives the connecting block 15 connected to it to slide inward at the same time. Thus, the connecting block 15 drives the positioning plate 16 to clamp and position the other two sides of the PCB board. This enables the clamping and positioning of PCB boards of different shapes and sizes, which is convenient for subsequent etching processing.

[0022] Preferably, the workbench 2 has sliding grooves 17 on all four sides of its surface, and the outer walls of the I-shaped block 8 and the T-shaped block 14 are slidably connected to the inner wall of the sliding grooves 17. The placement table 3 has connecting grooves 18 on all four sides, and the connecting grooves 18 and the sliding grooves 17 are connected.

[0023] When the I-shaped block 8 and the T-shaped block 14 slide, they can slide on the inner wall of the slide groove 17, while when the connecting block 1 9 and the connecting block 2 15 move, they can slide on the inner wall of the connecting groove 18, thereby preventing the placement platform 3 from blocking the connecting blocks.

[0024] Furthermore, connecting brackets 19 are slidably connected to both sides of the base 1, and electric telescopic rods 21 are fixedly connected to one side of each connecting bracket 19. Mounting blocks 22 are fixedly connected to the output ends of the electric telescopic rods 21. Connecting rods 26 are fixedly connected to the upper part of each connecting bracket 19. The upper part of the mounting blocks 22 is slidably connected to the outer wall of the connecting rods 26. An etcher 20 is mounted on one side of the mounting blocks 22. Electric push rods 24 are fixedly connected to one side of each mounting block 22. Mounting plates 25 are fixedly connected to the output ends of the electric push rods 24. The upper surface of the outer wall of the etcher 20 is fixedly connected to the mounting plate 25. On the lower surface of plate 25, support rods 23 are fixedly connected to one side of mounting block 22, and one side of mounting plate 25 is slidably connected to the outer wall of support rod 23; both sides of base 1 are fixedly connected to fixing brackets 27, one side of fixing bracket 27 is fixedly connected to motor 28, the output end of motor 28 is fixedly connected to rotating shaft 29, one end of rotating shaft 29 is rotatably connected to the inner side of fixing bracket 27, the lower part of connecting bracket 19 is threadedly connected to the outer wall of rotating shaft 29, the inner side of fixing bracket 27 is fixedly connected to guide rod 30, and the lower part of connecting bracket 19 is slidably connected to the outer wall of guide rod 30;

[0025] Specifically, by activating the electric push rod 24, the mounting plate 25 is moved downward, sliding on the outer wall of the support rod 23. This allows the mounting plate 25 to move the etcher 20 downward, so that it rests against the PCB board. Simultaneously, the electric telescopic rod 21 is activated, causing the mounting block 22 to slide on the outer wall of the connecting rod 26, thereby moving the etcher 20. The motor 28 is activated, causing the rotating shaft 29 to rotate. Under the guidance of the guide rod 30, the connecting frame 19 can be moved, allowing the etcher 20 to move back, forth, left, and right to process the PCB board.

[0026] Preferably, a rubber pad 31 is fixedly connected to one side of the positioning plate 16;

[0027] The rubber pad 31 provides protection for the PCB board.

[0028] Preferably, the connecting plates 6 are arranged in a cross configuration.

[0029] The working principle and usage process of this utility model are as follows: The PCB board is placed on two placement platforms 3. Then, the electric push rod 10 is activated, causing one of the connecting blocks 9 to slide. The connecting block 9 causes the I-beam block 8 to slide, which in turn causes the slider 4 to slide. When the slider 4 moves, it causes the connecting plate 6 to slide within the through groove 5. When the connecting plate 6 moves, the sliding rod 7 on its lower surface slides on the inner wall of the worktable 2, thereby pulling all four sliders 4 inward simultaneously. This causes two I-beam blocks 8 to slide inward simultaneously, causing the connecting block 9 connected to them to slide inward simultaneously. This allows the connecting block 9 to drive the positioning plate 16 to clamp and position both sides of the PCB board. Then, the motor 11 is activated, causing the gear 12 to rotate. The gear 12 causes the racks 13 on both sides to move inward simultaneously, thereby causing the racks 13 to pull the T-shaped block 14 inward simultaneously. The motor moves inward, causing the connecting block 25 connected to it to slide inward simultaneously. This allows the connecting block 25 to move the positioning plate 16 to clamp and position the other two sides of the PCB board, thus enabling the clamping and positioning of PCB boards of different shapes and sizes, facilitating subsequent etching processing. By activating the electric push rod 24, the mounting plate 25 is moved downward, sliding on the outer wall of the support rod 23. This allows the mounting plate 25 to move the etcher 20 downward, pressing it against the PCB board. Simultaneously, the electric telescopic rod 21 is activated, causing the mounting block 22 to slide on the outer wall of the connecting rod 26, thus moving the etcher 20. The motor 28 is activated, causing the rotating shaft 29 to rotate. Guided by the guide rod 30, the connecting frame 19 is moved, allowing the etcher 20 to move back, forth, left, and right to process the PCB board.
