Description

Technical Field

[0001] This utility model relates to the technical field of circuit board production equipment, specifically to an etching machine for circuit board production. Background Technology

[0002] A circuit board is a substrate used to support and connect electronic components. It achieves electrical connections between components through pre-designed conductive lines, while also providing mechanical fixation. It is the basic carrier for the normal operation of electronic equipment. A circuit board consists of an insulating substrate, a conductive layer, and a protective layer. The conductive layer is formed by etching copper foil with an etching machine used in circuit board production to form wires inside the conductive layer, thereby realizing the circuit connection of the circuit board.

[0003] In the prior art, patent publication number CN222016876U discloses a circuit board etching machine, including a base, a main body and a flipping mechanism fixedly mounted on the base, the flipping mechanism being located below the main body, a sliding mechanism on the base, the sliding mechanism being connected to the flipping mechanism, the flipping mechanism being slidably connected to the base through the sliding mechanism, the flipping mechanism including a flipping seat, a clamping mechanism on the flipping seat, and a circuit board mounted on the clamping mechanism;

[0004] This type of circuit board etching machine has the following disadvantages: the motor rotates to drive the sliding rail to move, which in turn drives the connector to move, causing the flipping seat to move, which in turn drives the clamping seat to clamp the circuit board laterally. Then, the electric push rod is activated to drive the connector to move, so that the clamping plate clamps the circuit board. Although it can clamp the circuit board in multiple directions, the operation process is cumbersome and affects the etching efficiency of the circuit board. Therefore, we propose an etching machine for circuit board production. Utility Model Content

[0005] The technical problem this invention aims to solve is to overcome existing defects and provide an etching machine for circuit board production. Through a fixing mechanism, an electric push rod drives a mounting block to move, which in turn moves a fixing plate, thereby horizontally fixing the circuit board. The telescopic end of the electric push rod continues to move, causing the fixing plate to move and driving a sliding rod to move. Through the cooperation of a fixing pin and a track groove, a gear rotates, driving a rack plate to move, which in turn causes adjacent vertical clamping plates to move towards each other, thus vertically clamping the circuit board. By simply controlling the operation of the electric push rod, the circuit board can be fixed in multiple directions, ensuring effective fixing while simplifying the process and improving etching efficiency. This effectively solves the problems in the background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an etching machine for circuit board production, comprising a support platform, an etching chamber fixedly connected to the left side of the upper surface of the support platform, a protective door hinged to the front surface of the etching chamber, a screw seat fixedly connected to the top wall of the etching chamber, an adjustable high-pressure nozzle provided on the front surface of the screw seat, and a fixing mechanism.

[0007] The fixing mechanism includes mounting blocks, clamping plates, rack plates, rotating cylinders, and gears. Adjustable mounting blocks are provided on both the left and right sides of the etching chamber. Each mounting block has symmetrically distributed sliding grooves on the side near the center of the etching chamber. Clamping plates symmetrically distributed vertically are slidably connected between two longitudinally adjacent sliding grooves. A rack plate is fixedly connected to the side of each clamping plate away from the center of the etching chamber. A rotating cylinder is rotatably connected inside each mounting block. A gear is fixedly connected to the end of each rotating cylinder near the center of the etching chamber. Each gear meshes with a rack plate located within the same mounting block. This mechanism is used for fixing... The mechanism uses an electric push rod to drive the mounting block to move, which in turn moves the fixing plate, thus horizontally fixing the circuit board. The telescopic end of the electric push rod then continues to move, causing the fixing plate to move, which in turn moves the sliding rod. Through the engagement of the fixing pin and the track groove, the gear rotates, causing the rack plate to move, which in turn moves the vertically adjacent clamping plates towards each other, thus vertically clamping the circuit board. By simply controlling the operation of the electric push rod, the circuit board can be fixed in multiple directions, ensuring effective fixing while simplifying the process and improving the etching efficiency.

[0008] Furthermore, a control switch assembly is fixedly connected to the right side of the upper surface of the support platform. The input end of the control switch assembly is electrically connected to an external power source to control the operation of electrical appliances.

[0009] Furthermore, the fixing mechanism also includes a fixing plate, a sliding rod, and fixing pins. The fixing plate is slidably connected to the side of the mounting block near the center of the etching chamber, and the sliding rod is fixedly connected to the side of the fixing plate away from the center of the etching chamber. The outer surface of the sliding rod away from the center of the etching chamber has a track groove. The upper side of the inner surface of the gear is fixedly connected to a fixing pin, and the fixing pin is slidably connected to the track groove on the same side. A spring is fixedly connected between the side of the sliding rod away from the center of the etching chamber and the inner wall of the mounting block on the same side to fix the circuit board laterally.

[0010] Furthermore, the fixing mechanism also includes electric push rods, which are fixedly connected to the left and right surfaces inside the etching chamber. The telescopic ends of the electric push rods are fixedly connected to the side of the mounting block away from the center of the etching chamber on the same side.

[0011] Furthermore, a screw is rotatably connected inside the screw seat, and a slider is threadedly connected to the middle of the outer surface of the screw. The rear surface of the slider is slidably connected to the inner wall of the screw seat. Corrugated pipes are fixedly connected between the upper and lower surfaces of the slider and the inner wall of the screw. The corrugated pipes are all sleeved on the outer surface of the screw. The high-pressure nozzle is fixedly connected to the front surface of the slider, and the height of the high-pressure nozzle is adjusted.

[0012] Furthermore, a motor is fixedly connected to the upper surface of the etching chamber, the lower end of the motor's output shaft is fixedly connected to the upper end of the screw, and the input end of the motor is electrically connected to the output end of the control switch group to provide driving force.

[0013] Furthermore, a waste liquid collection tank is fixedly connected to the lower interior of the etching chamber, and a filter cloth is fixedly connected inside the waste liquid collection tank to collect the etching liquid.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This etching machine for circuit board production has the following advantages:

[0015] The fixing mechanism drives the electric push rod to move the mounting block, which in turn moves the fixing plate, thus fixing the circuit board laterally.

Detailed Implementation

[0022] 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.

[0023] Please see Figure 1-5 This embodiment provides a technical solution: an etching machine for circuit board production, including a support platform 1. An etching chamber 2 is fixedly connected to the left side of the upper surface of the support platform 1. A protective door 5 is hinged to the front surface of the etching chamber 2. A screw seat 10 is fixedly connected to the top wall of the etching chamber 2. An adjustable high-pressure nozzle 9 is provided on the front surface of the screw seat 10. A control switch group 3 is fixedly connected to the right side of the upper surface of the support platform 1. The input end of the control switch group 3 is electrically connected to an external power source. A screw 11 is rotatably connected inside the screw seat 10. A slider 12 is threadedly connected to the middle of the outer surface of the screw 11. The rear surface of the slider 12 is slidably connected to the inner wall of the screw seat 10. Corrugated pipes are fixedly connected between the upper and lower surfaces of the slider 12 and the inner wall of the screw 11. The corrugated pipes are all sleeved on the outer surface of the screw 11 (to protect the screw 11 and prevent dust or impurities from sticking to the surface of the screw 11 and causing the screw 11 to jam). The high-pressure nozzle 9 is fixedly connected to the front surface of the slider 12. The upper surface of the etching chamber 2 is fixedly connected to the motor 4. The lower end of the output shaft of the motor 4 is fixedly connected to the upper end of the screw 11. The input end of the motor 4 is electrically connected to the output end of the control switch group 3. The control switch group 3 is operated to start the motor 4. The output shaft of the motor 4 rotates and drives the screw 11 to rotate, causing the slider 12 to move along the direction of the screw 11, which in turn drives the high-pressure nozzle 9 to move. After the high-pressure nozzle 9 is adjusted to a suitable height, the external etching liquid delivery pipe is connected to the high-pressure nozzle 9, so that the etching liquid is sprayed onto the upper surface of the circuit board through the high-pressure nozzle 9, thereby etching the circuit board. The lower side of the interior of the etching chamber 2 is fixedly connected to the waste liquid collection tank 6. The interior of the waste liquid collection tank 6 is fixedly connected to the filter cloth 7. The etching liquid falls into the waste liquid collection tank 6 under gravity. At the same time, the filter cloth 7 filters out large particulate impurities in the etching liquid. The etching chamber 2 also includes a fixing mechanism 8.

[0024] Fixing mechanism 8 includes mounting blocks 82, clamping plates 83, rack plates 84, rotating cylinders 88, and gears 87. Adjustable mounting blocks 82 are provided on both the left and right sides of the etching chamber 2. Each mounting block 82 has symmetrically distributed sliding grooves on the side closest to the center of the etching chamber 2. Clamping plates 83, symmetrically distributed vertically, are slidably connected between two longitudinally adjacent sliding grooves. Rack plates 84 are fixedly connected to the side of each clamping plate 83 furthest from the center of the etching chamber 2. Rotating cylinders 88 are rotatably connected inside each mounting block 82. Gears 87 are fixedly connected to the end of each rotating cylinder 88 closest to the center of the etching chamber 2. Each gear 87 is located on the same... The rack and pinion plate 84 inside the mounting block 82 is engaged with the fixing mechanism 8, which also includes a fixing plate 85, a slide rod 86, and a fixing pin 89. The fixing plate 85 is slidably connected to the side of the mounting block 82 closest to the center of the etching chamber 2, and the slide rod 86 is fixedly connected to the side of the fixing plate 85 furthest from the center of the etching chamber 2. A track groove is formed on the outer surface of the slide rod 86 furthest from the center of the etching chamber 2. A fixing pin 89 is fixedly connected to the upper surface of the inner surface of the gear 87, and the fixing pin 89 is slidably connected to the track groove on the same side. A spring is fixedly connected between the side of the slide rod 86 furthest from the center of the etching chamber 2 and the inner wall of the mounting block 82 on the same side. Mechanism 8 also includes electric push rods 81, which are fixedly connected to the left and right surfaces inside the etching chamber 2. The telescopic ends of the electric push rods 81, near the center of the etching chamber 2, are fixedly connected to the side of the mounting block 82 on the same side away from the center of the etching chamber 2. The input ends of the electric push rods 81 are electrically connected to the output ends of the control switch group 3. When the protective door 5 is opened and the circuit board is placed between the two mounting blocks 82, the control switch group 3 is operated to start the electric push rods 81. The telescopic ends of the electric push rods 81 push the two mounting blocks 82 to move towards each other, causing the fixing plates 85 on the left and right sides to move towards each other. When the two fixing plates 85 When the circuit board contacts the left and right sides respectively, the circuit board pushes the fixing plate 85 to move into the mounting block 82 on the same side, which in turn drives the slide rod 86 to move towards the mounting block 82 on the same side. The spring contracts and simultaneously drives the track groove to move (the track groove is a spiral groove with the central axis of the slide rod 86 as the axis of rotation). This causes the fixing pin 89 to move relative to the track groove, thereby driving the gear 87 to rotate (the central axes of the gear 87, slide rod 86 and rotating cylinder 88 coincide). This causes the two vertically adjacent rack plates 84 to move towards each other, which in turn drives the two vertically adjacent clamping plates 83 to move towards each other, thereby clamping and fixing the circuit board.

[0025] The working principle of the etching machine for circuit board production provided by this utility model is as follows: When using the etching machine to etch circuit boards, open the protective door 5 and place the circuit board between two mounting blocks 82. At this time, operate the control switch group 3 to start the electric push rod 81. The telescopic end of the electric push rod 81 pushes the two mounting blocks 82 to move towards each other, causing the fixing plates 85 on the left and right sides to move towards each other. When the two fixing plates 85 contact the left and right sides of the circuit board respectively, the circuit board pushes the fixing plates 85 to move inward towards the mounting block 82 on the same side, driving the slide rod 86 to move towards the mounting block 82 on the same side. The spring contracts, and at the same time, it drives the track groove to move (the track groove is a spiral groove with the central axis of the slide rod 86 as the axis of rotation), so that the fixing pin 89 interacts with the track groove. The relative movement causes the gear 87 to rotate (the central axes of the gear 87, slide bar 86, and rotating drum 88 coincide), causing the two vertically adjacent rack plates 84 to move towards each other, which in turn causes the two vertically adjacent clamping plates 83 to move towards each other, thereby clamping and fixing the circuit board. At this time, the control switch group 3 is operated to start the motor 4. The output shaft of the motor 4 rotates, causing the screw 11 to rotate, causing the slider 12 to move along the direction of the screw 11, which in turn moves the high-pressure nozzle 9. After the high-pressure nozzle 9 is adjusted to a suitable height, the external etching solution delivery pipe is connected to the high-pressure nozzle 9, so that the etching solution is sprayed onto the upper surface of the circuit board through the high-pressure nozzle 9, thereby etching the circuit board. Afterwards, the etching solution falls into the waste liquid collection tank 6 under gravity, while the filter cloth 7 filters out large particulate impurities in the etching solution.

[0026] It is worth noting that the motor 4 disclosed in the above embodiments is Y2-160, the electric push rod 81 is DT series electric push rod, and the control switch group 3 is provided with control buttons that correspond one-to-one with the motor 4 and the electric push rod 81 and are used to control their switching.

[0027] 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 content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
