[0002] PCB, whose Chinese name is printed circuit board and is commonly known as circuit board, is an important electronic component, a support for electronic components, and a carrier for electrical connection of electronic components. The production process of PCB board includes many processes such as blanking, drilling, electroless copper plating, grinding, electroplating, stripping, etching, etc. Among them, cleaning the circuit board is an important link. The circuit boards after different processes need to be sent into the cleaning machine for cleaning to remove solder resist, oil stains, fingerprints and other dirt, so as to avoid adverse effects on subsequent production and processing processes.

[0003] However, in the prior art, when transporting the circuit board to the cleaning machine for cleaning, if the number of circuit boards entering cannot be effectively controlled, multiple circuit boards will enter at the same time. This situation will not only cause uneven distribution of the cleaning liquid, making some circuit boards unable to fully contact the cleaning liquid, thus affecting the cleaning effect and reducing the quality of the circuit board; at the same time, collisions and squeezes are likely to occur between multiple circuit boards, resulting in damage to sensitive components on the circuit board and even damaging the structure of the entire circuit board. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem in the prior art that the spacing of the circuit board transported to the cleaning machine cannot be controlled, resulting in stacking of multiple circuit boards, and to propose a transportation control device for a circuit board cleaning machine.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A transportation control device for a circuit board cleaning machine, including a conveying frame, a stacking box is installed on the top of the conveying frame, a driving mechanism is installed below the conveying frame, and a transportation mechanism is installed at the bottom of the conveying frame;

[0006] The transportation mechanism includes a reciprocating plate and a track. A plurality of second rotating frames are fixedly connected to the top of the reciprocating plate. A rotating block is rotatably connected to the inner side of the second rotating frame. A stop push rod is fixedly connected to the outer surface of the rotating block, and a feeding rod is fixedly connected to the top of the outer surface of the rotating block. A limiting groove is opened on the inner side of the track, and a limiting hole is opened at the center of the bottom of the track. A limiting block is fixedly connected to the bottom of the reciprocating plate, and the limiting block is slidably connected with the limiting groove. A first rotating frame is fixedly connected to the bottom of the reciprocating plate, and the width of the limiting hole is smaller than the width of the inner side of the limiting hole.

[0007] Preferably, a push rod is rotatably connected to the inner side of the first rotating frame, and one end of the push rod is rotatably connected to a crank.

[0008] Preferably, one end of the crank is fixedly connected to the crank, and the weight of the stop push rod is greater than that of the feeding rod.

[0009] Preferably, the driving mechanism includes a bottom plate, and a driving motor is installed on one side of the top of the bottom plate. The output end of the driving motor is fixedly connected to a belt transmission assembly.

[0010] Preferably, one end of the inner side of the belt transmission assembly is fixedly connected to a central rod, and one end of the central rod is fixedly connected to one end of the crank.

[0011] Preferably, a support frame is rotatably connected to the outer surface of the central rod, and the bottom of the support frame is fixedly connected to the top of the bottom plate.

[0012] Preferably, a feeding port is fixedly communicated with the top of the stacking box. One end of the conveying frame is fixedly connected to a guiding frame, and a support rod is fixedly connected to the side wall of the guiding frame. The support rod is fixedly connected to the side wall of the track.

[0013] Compared with the prior art, the advantages and positive effects of the present utility model are as follows:

[0014] 1. In the present utility model, the crank is used as the power source of the system and performs circular motion around the central rod, which is converted into the pushing and pulling force on the push rod. The push rod, in cooperation with the first rotating frame, performs reciprocating motion along a complex trajectory and transmits the force to the reciprocating plate. The reciprocating plate, in cooperation with the limiting block and the limiting groove, performs horizontal linear reciprocating motion along the inner side of the track. During this process, the feeding rod cooperates with the reciprocating plate to push out the circuit boards inside the conveying frame one by one. Since the movement of the reciprocating plate is controllable, the spacing of the circuit boards pushed out by the feeding rod is also controllable, which enables the speed and spacing of the circuit boards entering the cleaning machine to be accurately controlled, ensuring that the circuit boards enter continuously during the cleaning process and avoiding stacking or congestion.

[0015] 2. In the present utility model, the stop push rod provides stable support and additional thrust for the feeding rod due to its weight, ensuring the stability and safety of the circuit board transportation. When the feeding rod returns after pushing, it rotates to overcome the reaction force of the circuit board, avoiding unconscious pushing, maintaining the efficiency and accuracy of the system. The stop push rod abuts against the reciprocating plate to form stable support, enabling the feeding rod to push the circuit board along a predetermined trajectory. The driving motor drives the central rod and the crank through the belt transmission assembly, thereby realizing the reciprocating motion of the feeding rod and automatically transporting the circuit boards. The guiding frame ensures that the circuit boards slide smoothly without deviating from the direction or colliding, improving the transportation efficiency and safety.

[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following further describes the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figure 1 - Figure 4 shown, the present utility model provides a transportation control device for a circuit board cleaning machine, including a conveyor frame 3, a stacking box 1 is installed on the top of the conveyor frame 3, a driving mechanism 7 is installed below the conveyor frame 3, and a transportation mechanism 6 is installed at the bottom of the conveyor frame 3;

[0024] The transportation mechanism 6 includes a reciprocating plate 64 and a track 68. A plurality of second rotating frames 65 are fixedly connected to the top of the reciprocating plate 64. A rotating block 69 is rotatably connected to the inner side of the second rotating frame 65. A stop pushing rod 66 is fixedly connected to the outer surface of the rotating block 69, and a feeding rod 67 is fixedly connected to the top of the outer surface of the rotating block 69. A limiting groove 681 is opened on the inner side of the track 68, and a limiting hole 682 is opened at the center of the bottom of the track 68. A limiting block 641 is fixedly connected to the bottom of the reciprocating plate 64. The limiting block 641 is slidably connected to the limiting groove 681. A first rotating frame 631 is fixedly connected to the bottom of the reciprocating plate 64. The width of the limiting hole 682 is smaller than the inner width of the limiting hole 682.

[0025] Specifically describe the specific settings and functions of this embodiment below. First, the crank 62, as the power source of this system, will perform circular motion around the central rod 61. Through the special design of the crank 62, this circular motion is converted into the driving force and pulling force on the push rod 63.

[0026] Driven by the crank 62, the push rod 63 will perform reciprocating motion. This reciprocating motion is not a simple linear motion, but rather cooperates with the first rotating frame 631 to form a complex motion trajectory. The design of the first rotating frame 631 enables the push rod 63 to accurately transmit force to the reciprocating plate 64 during movement.

[0027] Under the action of the push rod 63, the reciprocating plate 64 will perform horizontal linear motion. This linear motion is achieved through the cooperation of the limit block 641 and the limit groove 681. The limit block 641 is fixed on the reciprocating plate 64, while the limit groove 681 is located inside the track 68. When the reciprocating plate 64 moves within the track 68, the limit block 641 will slide within the limit groove 681, thereby ensuring that the reciprocating plate 64 can only perform horizontal linear motion and restricting its movement space in the vertical direction.

[0028] With the continuous circular motion of the crank 62, the push rod 63 will continuously apply driving force and pulling force to the reciprocating plate 64, causing the reciprocating plate 64 to perform continuous linear reciprocating motion inside the track 68. During this process, the feeding rod 67 will cooperate with the reciprocating plate 64 to push out the circuit boards inside the conveying frame 3 one by one. Since the movement of the reciprocating plate 64 is controllable, the distance between the circuit boards pushed out by the feeding rod 67 is also controllable. In this way, we can precisely control the speed and spacing of the circuit boards entering the cleaning machine, ensuring that during the cleaning process, the circuit boards can enter continuously and there will be no stacking or congestion.

[0029] Embodiment Two: As Figure 2 - Figure 4 shown, the push rod 63 is rotatably connected inside the first rotating frame 631, and one end of the push rod 63 is rotatably connected to the crank 62. One end of the crank 62 is fixedly connected to the crank 62, and the weight of the stop push rod 66 is greater than that of the feeding rod 67. The driving mechanism 7 includes a bottom plate 71, and a driving motor 74 is installed on one side of the top of the bottom plate 71. The output end of the driving motor 74 is fixedly connected to a belt transmission assembly 73. One end inside of the belt transmission assembly 73 is fixedly connected to the central rod 61, and one end of the central rod 61 is fixedly connected to one end of the crank 62. The outer surface of the central rod 61 is rotatably connected to a support frame 72, and the bottom of the support frame 72 is fixedly connected to the top of the bottom plate 71. The top of the stacking box 1 is fixedly communicated with a feeding port 2, one end of the conveying frame 3 is fixedly connected to a guiding frame 5, a support rod 4 is fixedly connected to the side wall of the guiding frame 5, and the support rod 4 is fixedly connected to the side wall of the track 68.

[0030] The effect achieved by the entire embodiment is as follows. First, since the weight of the stop push rod 66 is greater than that of the feeding rod 67, it is ensured that when the feeding rod 67 pushes the circuit board forward, the stop push rod 66 can provide stable support and additional thrust for it. This design not only improves the feeding efficiency but also ensures the stability and safety of the circuit board during transportation.

[0031] However, when the feeding rod 67 completes a pushing action and is ready to return, due to the rotational space between the feeding rod 67 and the stop push rod 66, when the feeding rod 67 contacts the subsequent circuit board, it will receive a reaction force from the circuit board. The feeding rod 67 directly overcomes this reaction force by rotating, thus avoiding unconscious pushing actions and ensuring the working efficiency and accuracy of the system.

[0032] During the previous pushing process, the stop push rod 66 will abut against the reciprocating plate 64 to form a stable support point. In this way, even if the feeding rod 67 receives a reaction force from the circuit board, it cannot rotate but continues to push the circuit board forward along the predetermined trajectory. This design ensures the stability and accuracy of the feeding process and improves the performance of the entire system.

[0033] The driving motor 74 serves as the power source of the entire system and transmits the acting force to the central rod 61 through the belt transmission assembly 73. The central rod 61 is connected to the crank 62. When the central rod 61 rotates, it drives the crank 62 to perform corresponding activities. The activities of the crank 62 further drive the reciprocating movement of the feeding rod 67, thereby realizing the automatic transportation of the circuit board.

[0034] During the transportation of the circuit board, the guide frame 5 plays a key guiding role. Under the guidance of the guide frame 5, the circuit board can smoothly slide along the predetermined trajectory, ensuring that it will not deviate from the direction or collide during transportation. This design not only improves the transportation efficiency but also ensures the safety of the circuit board during transportation.

[0035] The usage method and working principle of this device: During transportation, the driving motor 74 can drive the belt transmission assembly 73 to move, transmit the acting force to the central rod 61 through the belt transmission assembly 73, and then drive the crank 62 to move, so as to facilitate the operation of transporting the circuit board. When the circuit boards move, they will smoothly slide under the guidance of the guide frame 5 until they enter the inside of the cleaning machine.

[0036] When the crank 62 rotates, it performs a circular motion centered on the central rod 61. During this process, the crank 62 drives the push rod 63 to move, enabling the push rod 63 and the first rotating frame 631 to work together to apply a force to the reciprocating plate 64. When the reciprocating plate 64 moves, due to the presence of the limit block 641, it can maintain a horizontal linear motion. At the same time, the cooperation between the limit block 641 and the limit groove 681 limits the movement space of the reciprocating plate 64 in the vertical direction, ensuring the stability of the reciprocating plate 64 during movement and preventing shaking and skew.

[0037] With the circular motion of the crank 62, the push rod 63 is alternately subjected to a driving force and a pulling force, causing the reciprocating plate 64 to perform a linear reciprocating motion inside the track 68. During this process, the feeding rod 67 pushes the circuit board inside the conveying frame 3 to move, which not only facilitates the transportation of the circuit board but also can accurately control the moving distance of the circuit board, ensuring that the circuit board can enter the cleaning machine successively and orderly during the cleaning process, avoiding stacking.

[0038] During the pushing process, the presence of the stop push rod 66 enables the feeding rod 67 to effectively push the circuit board. Since the weight of the stop push rod 66 is greater than that of the feeding rod 67, when the feeding rod 67 contacts the subsequent circuit board during its return, it will receive a reaction force from the circuit board. However, due to the rotational space between the feeding rod 67 and the stop push rod 66, the feeding rod 67 cannot continue to push the circuit board to move.

[0039] During the previous pushing process, the stop push rod 66 abuts against the reciprocating plate 64, so that even if the feeding rod 67 receives a reaction force from the circuit board, it cannot rotate, thus ensuring that the feeding rod 67 can continuously and stably push the circuit board to move.

[0040] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
