Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5 , the present invention provides a technical solution: a chemical circuit board washing machine for circuit board production, including a workbench 1. A circuit board washing tank 3 for washing the circuit board is opened on one side of the surface of the workbench 1. A drying tank 4 is arranged on one side of the washing tank 3. A conveying assembly is installed on one side of the drying tank 4. A placing groove 11 is arranged on one side of the conveying assembly. Air pumps 6 are installed on both side walls of the workbench 1. One end of the air pump 6 is connected with an air outlet pipe 601. One end of the air outlet pipe 601 passes through both side walls of the workbench 1 and is arranged on the side close to the conveying assembly. Support frames 2 are installed at both top ends of the workbench 1 through moving assemblies. A cylinder 8 is installed at the top end of the support frame 2. The piston rod end of the cylinder 8 passes through the bottom end of the support frame 2 and is connected with a mounting rack 12. Two relatively moving L-shaped moving blocks 14 are installed at the bottom end of the mounting rack 12. A limiting assembly is arranged on the inner walls of the two L-shaped moving blocks 14. A plurality of water draining holes 1402 are opened on the surface of the L-shaped moving block 14;

[0024] During use, the two L-shaped moving blocks 14 can be combined together to form a structure similar to a water draining basket, so that the circuit board can fully contact the cleaning liquid during the cleaning process. At the same time, when the circuit board is moved out of the washing tank 3, the water draining holes 1402 on the L-shaped moving block 14 can quickly drain the excess water, reducing the residual water stains on the circuit board. The water draining basket structure formed by the L-shaped moving blocks 14 can firmly fix the circuit board and prevent it from shaking or falling off during the movement and cleaning process.

[0025] The transmission assembly includes a conveyor belt 5, a transmission motor 501, an active roller 502 and a driven roller 503. The output shaft of the transmission motor 501 is fixedly connected to one end of the active roller 502, and the other end of the active roller 502 is rotatably mounted on an inner wall of one side of the workbench 1. Both ends of the driven roller 503 are rotatably mounted on the inner walls of both sides of the workbench 1. The active roller 502 and the driven roller 503 are connected through the transmission of the conveyor belt 5. The stable installation of the active roller 502 and the driven roller 503 ensures the stable operation of the conveyor belt 5, reduces the risk of circuit boards falling or being damaged due to shaking or deviation of the conveyor belt 5, and the stable output of the transmission motor 501 also ensures the continuity and reliability of the transmission process.

[0026] The moving assembly includes a first driving motor 7, a first threaded rod 702 and a round rod 703. First moving grooves 701 are provided on the top of both sides of the workbench 1. The output shaft of the first driving motor 7 is fixedly connected to one end of the first threaded rod 702. The other end of the first threaded rod 702 is rotatably mounted on an inner wall of one side of one of the first moving grooves 701. Both ends of the round rod 703 are fixedly mounted on the inner walls of both sides of the other first moving groove 701. One side of the bottom end of the support frame 2 is threadedly mounted on the surrounding outer walls of the first threaded rod 702. The other end of the bottom end of the support frame 2 is slidably mounted on the outer wall of the round rod 703. The first driving motor 7 drives the first threaded rod 702 to rotate. Since one side of the bottom end of the support frame 2 is threadedly mounted on the surrounding outer walls of the first threaded rod 702, the support frame 2 will move linearly along the direction of the first threaded rod 702, so that the position control of the circuit board during the transmission process is more precise, which can meet the needs of high-precision production.

[0027] A second movable groove 1201 is provided inside the mounting frame 12, and a third drive motor 13 is installed at one end of the mounting frame 12. The output shaft of the third drive motor 13 is fixedly connected to a bidirectional threaded rod 1301. One end of the bidirectional threaded rod 1301 passes through the second movable groove 1201 and is rotatably installed on an inner wall of one side of the second movable groove 1201. The top ends of the two L-shaped movable blocks 14 are threadedly connected to the surfaces of the bidirectional threaded rod 1301. By adjusting the rotation speed and rotation direction of the third drive motor 13, the moving speed and direction of the two L-shaped movable blocks 14 can be precisely controlled, which helps prevent the circuit board from shaking or falling off during movement or cleaning.

[0028] The limit assembly includes a limit block 1401 and a limit groove. One end of the limit block 1401 is installed on the inner wall of one of the L-shaped moving blocks 14, and the limit groove is opened on the inner wall of the other L-shaped moving block 14. The limit block 1401 is slidably installed inside the limit groove. By sliding the limit block 1401 in the limit groove, the relative position between the two L-shaped moving blocks 14 can be accurately controlled to ensure that they will not exceed the predetermined range or be misplaced during movement.

[0029] On the surface of the drying tank 4, there are two relatively movable drying top covers 901 installed. On the inner wall of one side of the two drying top covers 901, a second bidirectional screw 902 is threadedly connected. One end of the second bidirectional screw 902 passes through one side of one of the drying top covers 901 and extends to the outer wall of one side of the workbench 1, and one end of the second bidirectional screw 902 is fixedly connected to a second driving motor 9. On the inner wall of the other side of the two drying top covers 901, a limiting rod 903 is slidably connected. Through the drive of the second bidirectional screw 902, the drying tank 4 can be quickly and accurately opened or closed.

[0030] An inclined plate 10 is installed between the conveyor belt 5 and the placement groove 11. The upper end of the inclined plate 10 is connected to one side of the conveyor belt 5, and the lower end of the inclined plate 10 is connected to one end of the placement groove 11. A buffer pad is provided at the inner bottom end of the placement groove 11. The design of the inclined plate 10 enables the materials transported from the conveyor belt 5 to smoothly transition into the placement groove 11, avoiding possible collisions when the materials directly fall. The setting of the buffer pad further absorbs the impact force when the materials fall, protecting the placement groove 11 and its surrounding equipment from damage.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
