Description

Technical Field

[0001] This utility model relates to the field of cleaning equipment technology, and more specifically, to an ultrasonic cleaning device for water-based soldering. Background Technology

[0002] Water-based soldering typically refers to the soldering process using water-soluble flux. In the process of circuit board manufacturing and assembly, water-based soldering is often used when processing circuit boards with high line density and smaller component sizes. Before soldering, the surface of the circuit board usually needs to be cleaned using ultrasonic cleaning equipment.

[0003] In the existing technology, when it is necessary to use an ultrasonic cleaner to clean circuit boards, the operator usually puts the circuit board into the cleaner manually and immerses it in the cleaning solution. However, this method is not only inconvenient to operate, but also easy to damage the surface of the circuit board during the placement and removal process. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model proposes an ultrasonic cleaning device for water-based soldering.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an ultrasonic cleaning device for water-based soldering, comprising a cleaning machine body, a mounting plate fixedly connected to one side of the cleaning machine body, a rotary motor fixedly connected to one side of the mounting plate, a transmission shaft fixedly connected to the output end of the rotary motor, a first bevel gear fixedly connected to the outer wall of the transmission shaft, a second bevel gear meshing with one side of the first bevel gear, a limiting groove formed at the bottom of the second bevel gear, a limiting block rotatably connected to the inner wall of the limiting groove, a mounting rod fixedly connected to the bottom of the limiting block, the mounting rod fixedly connected to the top of the cleaning machine body, a threaded cylinder fixedly connected to the inner wall of the second bevel gear, a threaded rod threadedly connected to the inner wall of the threaded cylinder, a circular plate fixedly connected to the bottom of the threaded rod, a side plate rotatably connected to the outer wall of the circular plate, a placement frame fixedly connected to one side of the side plate, the placement frame being disposed on the inner wall of the cleaning machine body, and a strip groove formed on the outer wall of the placement frame.

[0006] Furthermore, a frame plate is fixedly connected to one side of the inner wall of the cleaning machine body, and a limiting block is fixedly connected to the side of the placement frame away from the side plate, and the limiting block is slidably connected to the inner wall of the frame plate.

[0007] Furthermore, a vertical plate is fixedly connected to one side of the cleaning machine body, the top of the vertical plate is inclined, and a fan is fixedly connected to the inclined part of the vertical plate.

[0008] Furthermore, a baffle plate is fixed to the top end of the threaded rod, and the baffle plate is circular in shape.

[0009] Furthermore, a water outlet pipe is fixedly connected to the bottom of one side of the cleaning machine body, and a valve is fixedly connected to the outer wall of the water outlet pipe.

[0010] Furthermore, the bottom of the cleaning machine body is rotatably connected to a movable wheel, and a brake pad is provided on one side of the movable wheel. There are four sets of movable wheels and brake pads, which are symmetrically distributed on the bottom of the cleaning machine body.

[0011] The technical effects and advantages of this utility model of an ultrasonic cleaning device for water-based soldering are as follows:

[0012] The rotating motor drives the transmission shaft and the first bevel gear to rotate. When the first bevel gear rotates, it drives the second bevel gear and the threaded cylinder to rotate.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0021] Example 1

[0022] Reference Figure 1-5 An ultrasonic cleaning device for water-based soldering includes a cleaning machine body 1. A mounting plate 2 is fixedly connected to one side of the cleaning machine body 1. A rotary motor 3 is fixedly connected to one side of the mounting plate 2. A transmission shaft 4 is fixedly connected to the output end of the rotary motor 3. A first bevel gear 5 is fixedly connected to the outer wall of the transmission shaft 4. A second bevel gear 6 meshes with one side of the first bevel gear 5. A limiting groove is formed at the bottom of the second bevel gear 6. A limiting ring 7 is rotatably connected to the inner wall of the limiting groove. An installation rod 8 is fixedly connected to the bottom of the limiting ring 7. The installation rod 8 is fixedly connected to the top of the cleaning machine body 1. A threaded cylinder 9 is fixedly connected to the inner wall of the threaded cylinder 9. A threaded rod 10 is threadedly connected to the inner wall of the threaded cylinder 9. A circular plate 11 is fixedly connected to the bottom of the threaded rod 10. A side plate 12 is rotatably connected to the outer wall of the circular plate 11. A placement frame 13 is fixedly connected to one side of the side plate 12. The placement frame 13 is disposed on the inner wall of the cleaning machine body 1. A strip groove is formed on the outer wall of the placement frame 13.

[0023] To address the inconvenience of placing and removing circuit boards during cleaning, when cleaning circuit boards requiring soldering, the circuit boards can be placed in the placement frame 13. After placement, the rotary motor 3 can be started. When the rotary motor 3 drives the transmission shaft 4 to rotate, it will also drive the first bevel gear 5 on the outer wall of the transmission shaft 4 to rotate. When the first bevel gear 5 rotates, it will drive the second bevel gear 6, which is meshed on one side, to rotate as well. By providing a limiting groove at the bottom of the second bevel gear 6, the limiting ring 7 provided in the limiting groove can maintain the position of the rotating second bevel gear 6. When the machine is in motion, it will cause the threaded cylinder 9 on the inner wall to rotate. When the threaded cylinder 9 rotates, it will drive the threaded rod 10 connected to the inner wall to move downward. When the threaded rod 10 moves downward, it will push the bottom circular plate 11 and the side plate 12 to move downward together. When the side plate 12 moves downward, it will drive the placement frame 13 on one side to move downward together until the circuit board in the placement frame 13 is submerged in the cleaning machine body 1. The circuit board can be cleaned through the cleaning machine body 1. When it is necessary to remove the circuit board, the rotary motor 3 can be rotated in the opposite direction to drive the threaded rod 10, the circular plate 11, the side plate 12 and the placement frame 13 to move upward together, so as to facilitate the removal of the circuit board.

[0024] Reference Figure 4 A frame plate 15 is fixedly connected to one side of the inner wall of the cleaning machine body 1, and a limiting block 14 is fixedly connected to the side of the placement frame 13 away from the side plate 12. The limiting block 14 is slidably connected to the inner wall of the frame plate 15.

[0025] When the placement frame 13 moves, it can cause the limiting block 14 on one side to slide within the frame plate 15. The movement trajectory of the placement frame 13 can be limited by the sliding of the limiting block 14 within the frame plate 15.

[0026] Reference Figure 1 A vertical plate 16 is fixedly connected to one side of the cleaning machine body 1. The top of the vertical plate 16 is inclined, and a fan 17 is fixedly connected to the inclined part of the vertical plate 16.

[0027] By setting a vertical plate 16 on one side of the cleaning machine body 1, it is convenient to install the fan 17. Since the fan 17 is installed at the top of the vertical plate 16 at an angle, the blown airflow can be directed towards the placement frame 13, which is beneficial to blow away the cleaning liquid on the surface of the circuit board.

[0028] Reference Figure 4 A baffle 18 is fixed to the top end of the threaded rod 10, and the baffle 18 is circular in shape.

[0029] By providing a circular baffle 18 at the top of the threaded rod 10, the threaded rod 10 can be prevented from moving out of the threaded cylinder 9 when it moves downward.

[0030] Reference Figure 1 A water outlet pipe 19 is fixedly connected to the bottom of one side of the cleaning machine body 1, and a valve 20 is fixedly connected to the outer wall of the water outlet pipe 19.

[0031] By setting a water outlet pipe 19 at the bottom of the cleaning machine body 1, the waste cleaning liquid inside the cleaning machine body 1 can be discharged through the water outlet pipe 19 by opening the valve 20 after cleaning.

[0032] Reference Figure 1 The bottom of the cleaning machine body 1 is rotatably connected to a movable wheel 21. A brake pad 22 is provided on one side of the movable wheel 21. There are four sets of movable wheels 21 and brake pads 22, which are symmetrically distributed at the bottom of the cleaning machine body 1.

[0033] By setting four sets of casters 21 at the bottom of the cleaning machine body 1, the position of the cleaning machine body 1 can be changed by the casters 21 when it is necessary to move the cleaning machine body 1, and the position of the casters 21 can be fixed by the brake pads 22 when necessary.

[0034] Working Principle: To solve the problem of inconvenient placement and removal of circuit boards during cleaning, when cleaning circuit boards that require soldering, the circuit boards can be placed in the placement frame 13. After placement, the rotary motor 3 can be started. When the rotary motor 3 drives the transmission shaft 4 to rotate, it will drive the first bevel gear 5 on the outer wall of the transmission shaft 4 to rotate together. When the first bevel gear 5 rotates, it will drive the second bevel gear 6 meshing on one side to rotate together. By opening a limiting groove at the bottom of the second bevel gear 6, the position of the rotating second bevel gear 6 can be maintained by the limiting ring 7 set in the limiting groove. When the second bevel gear 6 rotates, it will drive the threaded cylinder 9 on the inner wall to rotate. When the threaded cylinder 9 rotates, it will drive the threaded rod 10 connected to the inner wall to move downward. When the threaded rod 10 moves downward, it will push the bottom circular plate 11 and the side plate 12 to move downward together. When the side plate 12 moves downward, it will drive the placement frame 13 on one side to rotate together. The frame 13 moves downwards together. When the frame 13 moves, the limiting block 14 on one side can slide within the frame plate 15. The movement trajectory of the frame 13 can be limited by the sliding of the limiting block 14 within the frame plate 15 until the circuit board in the frame 13 is submerged in the cleaning machine body 1. The circuit board can be cleaned by the cleaning machine body 1. When it is necessary to remove the circuit board, the rotary motor 3 can be rotated in the opposite direction to drive the threaded rod 10, the round plate 11, the side plate 12 and the frame 13 to move upwards together, making it easier to remove the circuit board. By setting a water outlet pipe 19 at the bottom of the cleaning machine body 1, the waste cleaning liquid in the cleaning machine body 1 can be discharged through the water outlet pipe 19 by opening the valve 20 after cleaning. By setting a vertical plate 16 on one side of the cleaning machine body 1, it is easy to install the fan 17. Since the fan 17 is installed at the top of the vertical plate 16 at an angle, the blown airflow is directed towards the frame 13, which is beneficial to blow away the cleaning liquid on the surface of the circuit board.

[0035] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
