Description

Technical Field

[0001] This utility model relates to the field of circuit board processing, and in particular to a printed circuit board etching device. Background Technology

[0002] Etching is a crucial step in the manufacturing process of printed circuit boards, as it determines the final layout and conductivity of the circuit board. Traditional etching equipment has some significant shortcomings in operation. Most existing etching equipment adopts a fixed etching mode, in which the circuit board is placed in the equipment and etched on one side of the circuit board by etching solution. However, this design has obvious limitations.

[0003] Specifically, once one side of a circuit board has been etched, if the other side needs to be etched, the operator usually needs to manually remove the circuit board from the device, flip it over, and then put it back into the device for etching. This process not only increases the operator's workload but may also lead to a decrease in etching accuracy because it is difficult to ensure the consistency of the etching positions on both sides of the circuit board when manually flipping it over.

[0004] Therefore, it is necessary to provide a new printed circuit board etching apparatus to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a printed circuit board etching device.

[0006] The printed circuit board etching device provided by this utility model includes: a frame, a clamping seat, a connecting frame, and a driving mechanism. An etching pool for receiving etching solution is installed at the bottom of the frame, and a conveyor shaft for conveying printed circuit boards is installed at the top of the frame. Etching machines are symmetrically installed at the top of the frame. A clamping seat is installed between the two etching machines in the middle of the frame. A clamping head is installed on one side of the clamping seat. An inclined connecting frame is installed at the top of the frame. The connecting frame is installed in conjunction with two corresponding clamping seats. A driving mechanism for driving the clamping seats to rotate is installed between the connecting frame and the clamping seats.

[0007] Preferably, guide rods are symmetrically fixedly connected to one side of the clamping head, and two sets of guide rods are slidably connected to the corresponding clamping seats. Springs are sleeved on the outer walls of several guide rods, and the two ends of the springs are fixedly connected to one side of the clamping seat and the clamping head, respectively.

[0008] Preferably, the assembly includes an electric push rod, an L-shaped bracket, a gear, an L-shaped connecting rod, a rack, a threaded rod, a clamping motor, and a rotary motor. Electric push rods are symmetrically fixedly connected to both sides of the frame. An L-shaped bracket is fixedly connected to the output end of each electric push rod. One end of each of the two L-shaped brackets is fixedly connected to one side of the connecting frame. A gear is rotatably connected inside the connecting frame. L-shaped connecting rods are symmetrically slidably connected to the inner wall of the connecting frame. A rack is fixedly connected to the side of each of the two L-shaped connecting rods that is close to each other, and both racks mesh with the gear. A threaded rod is rotatably connected inside the connecting frame, and one of the L-shaped connecting rods is threadedly connected to the threaded rod. A clamping motor is fixedly connected to one side of the connecting frame, and the output end of the clamping motor is fixedly connected to one end of the threaded rod. The end of the L-shaped connecting rod away from the rack is rotatably connected to the clamping seat. A rotary motor is fixedly connected to the end of the L-shaped connecting rod close to the clamping seat, and the output end of the rotary motor is fixedly connected to the clamping seat.

[0013] Preferably, the bottom of the frame is symmetrically fixedly connected with feet.

[0014] Compared with related technologies, the printed circuit board etching device provided by this utility model has the following advantages:

[0015] Improve etching efficiency:

[0016] This device, through its automated design, enables automatic clamping, flipping, and etching of circuit boards, eliminating the tedious step of manual flipping and thus significantly improving etching efficiency.

[0017] Meanwhile, because the device can continuously etch both sides of the circuit board, waiting time is reduced, further improving production efficiency.

[0018] Improve etching precision:

[0019] The clamping mechanism in the device is ingeniously designed to hold the circuit board stably, preventing it from moving or deforming during the etching process, thus ensuring the accuracy of the etching.

[0020] In addition, by precisely controlling the movement of the clamping motor and the rotary motor, the flipping angle of the circuit board can be precisely adjusted to ensure the consistency of the etching positions on both sides;

[0021] Reduce labor intensity:

[0022] Traditional etching equipment requires operators to manually flip the etching plates, which increases labor intensity; while this equipment, through its automated design, reduces the burden on operators and lowers labor intensity.

[0023] At the same time, the device is easy to operate, reducing the skill requirements for operators and enabling more people to perform this job. Attached Figure Description

[0028] 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.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please see Figure 1-3A printed circuit board etching apparatus includes: a frame 1, a clamping seat 5, a connecting frame 7, and a drive mechanism. An etching pool 2 for receiving etching solution is installed at the bottom of the frame 1. A conveyor shaft 3 for conveying printed circuit boards is installed at the top of the frame 1. Etching machines 4 are symmetrically installed at the top of the frame 1. A clamping seat 5 is installed between the two etching machines 4 in the middle of the frame 1. A clamping head 6 is installed on one side of the clamping seat 5. An inclined connecting frame 7 is installed at the top of the frame 1. The connecting frame 7 cooperates with two corresponding clamping seats 5. A drive mechanism for driving the clamping seats 5 to rotate is installed between the connecting frame 7 and the clamping seats 5. The distance between the axis of the clamping seat 5 and the clamping head 6 is smaller than the distance between one end of the L-shaped connecting rod 13 and the connecting frame 7. A rubber pad is fixedly connected to one end of the clamping head 6. Machine feet are symmetrically fixedly connected to the bottom of the frame 1.

[0031] Please see Figure 2-3 A guide rod 8 is symmetrically fixedly connected to one side of the clamping head 6. Two sets of guide rods 8 are slidably connected to the corresponding clamping seat 5. A spring 9 is sleeved on the outer wall of several guide rods 8. The two ends of the spring 9 are fixedly connected to the clamping seat 5 and one side of the clamping head 6, respectively. A limit block 18 is fixedly connected to the end of the guide rod 8 away from the clamping head 6.

[0032] It should be noted that the combination of guide rod 8 and spring 9 provides a buffer for clamping head 6, preventing the circuit board from being damaged by excessive pressure during clamping; at the same time, limit block 18 restricts the sliding range of guide rod 8, preventing it from being damaged due to excessive sliding.

[0033] Please see Figure 2-3 The frame 1 includes an electric push rod 10, an L-shaped bracket 11, a gear 12, an L-shaped connecting rod 13, a rack 14, a threaded rod 15, a clamping motor 16, and a rotary motor 17. Electric push rods 10 are symmetrically fixedly connected to both sides of the frame 1. L-shaped brackets 11 are fixedly connected to the output ends of the electric push rods 10. One end of each of the two L-shaped brackets 11 is fixedly connected to one side of the connecting frame 7. Gears 12 are rotatably connected inside the connecting frame 7. L-shaped connecting rods 13 are symmetrically slidably connected to the inner wall of the connecting frame 7. Racks 14 are fixedly connected to the sides of the two L-shaped connecting rods 13 that are close to each other. Two racks... All 14 are meshed with gear 12. A threaded rod 15 is rotatably connected inside the connecting frame 7. One of the L-shaped connecting rods 13 is threadedly connected to the threaded rod 15. A clamping motor 16 is fixedly connected to one side of the connecting frame 7. The output end of the clamping motor 16 is fixedly connected to one end of the threaded rod 15. The end of the L-shaped connecting rod 13 away from the rack 14 is rotatably connected to the clamping seat 5. A rotary motor 17 is fixedly connected to the end of the L-shaped connecting rod 13 near the clamping seat 5. The output end of the rotary motor 17 is fixedly connected to the clamping seat 5. Both the clamping motor 16 and the rotary motor 17 are geared motors.

[0034] It should be noted that: once the circuit board is in place, the device is ready to enter the clamping stage; at this time, the clamping motor 16 is started.

[0035] The output shaft of the clamping motor 16 drives the threaded rod 15 to rotate; since one of the L-shaped connecting rods 13 is threadedly connected to the threaded rod 15, the L-shaped connecting rod 13 will move along the axial direction of the threaded rod 15 when the threaded rod 15 rotates.

[0036] Meanwhile, since the two L-shaped connecting rods 13 are linked by the cooperation of the rack 14 and the gear 12, when one L-shaped connecting rod 13 moves, the other L-shaped connecting rod 13 will also move accordingly, so that the two L-shaped connecting rods 13 move closer to each other.

[0037] As the L-shaped connecting rods 13 move, they respectively drive their respective clamping seats 5 and clamping heads 6 to move closer to the circuit board until the clamping heads 6 clamp the circuit board tightly; at this time, the circuit board is stably fixed between the two clamping seats 5.

[0038] The working principle of the printed circuit board etching device provided by this utility model is as follows:

[0039] Initial state and circuit board loading:

[0040] Before the device starts working, the two clamping seats 5 are located on both sides of the frame 1, and the clamping heads 6 are in the open state, with the distance between them reaching the maximum so that the printed circuit board can be easily placed in.

[0041] The operator places the printed circuit board to be etched in the predetermined position between the two clamping heads 6; at this time, the circuit board is not yet clamped and is in a free state;

[0042] Circuit board positioning and clamping:

[0043] Once the circuit board is in place, the device is ready to enter the clamping stage; at this time, the clamping motor 16 is started.

[0044] The output shaft of the clamping motor 16 drives the threaded rod 15 to rotate; since one of the L-shaped connecting rods 13 is threadedly connected to the threaded rod 15, the L-shaped connecting rod 13 will move along the axial direction of the threaded rod 15 when the threaded rod 15 rotates.

[0045] Meanwhile, since the two L-shaped connecting rods 13 are linked by the cooperation of the rack 14 and the gear 12, when one L-shaped connecting rod 13 moves, the other L-shaped connecting rod 13 will also move accordingly, so that the two L-shaped connecting rods 13 move closer to each other.

[0046] As the L-shaped connecting rods 13 move, they respectively drive their respective clamping seats 5 and clamping heads 6 to move closer to the circuit board until the clamping heads 6 clamp the circuit board tightly; at this time, the circuit board is stably fixed between the two clamping seats 5.

[0047] Circuit board flipping and etching:

[0048] Once the circuit board is clamped and stabilized, the device is ready to enter the flipping stage; at this time, the rotary motor 17 is started.

[0049] The output shaft of the rotary motor 17 is fixedly connected to the clamping seat 5. Therefore, when the rotary motor 17 is started, it will drive the clamping seat 5 and the circuit board to rotate 180 degrees together.

[0050] After the flipping is completed, the original unetched side of the circuit board is now facing either the first etching machine 4 or the second etching machine 4, depending on which etching machine the circuit board was facing initially;

[0051] Next, start the first etching machine 4 or the second etching machine 4 to perform etching operation on the other side of the circuit board; the etching solution is drawn from the etching pool 2 and sprayed evenly on the surface of the circuit board through the nozzle of the etching machine 4 to complete the etching process.

[0052] Security and protection mechanisms:

[0053] Throughout the operation, the device is also equipped with a series of safety and protection mechanisms; for example, the combination of guide rod 8 and spring 9 provides a buffer for clamping head 6 to prevent the circuit board from being damaged by excessive pressure during clamping; at the same time, limit block 18 restricts the sliding range of guide rod 8 to prevent it from being damaged due to excessive sliding.

[0054] In addition, a rubber pad is installed at one end of the clamping head 6 to increase the friction between the clamping head and the circuit board and to prevent the circuit board from sliding or shifting during the etching process;

[0055] The use of a geared motor clamping motor 16 and a rotary motor 17 ensures smooth and precise control of the movement, reducing the impact and vibration on the circuit board.

[0056] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
