[0002] With the rapid development of electronic technology and the popularization of electronic products, circuit boards, as the core components of electronic devices, have an increasing demand. The circuit board manufacturing technology is also constantly advancing, developing towards the direction of high precision, high density, and high reliability. Green oil, that is, liquid photoimageable solder resist, is an indispensable material in the circuit board manufacturing process. It is coated on the circuits and substrates that do not need to be soldered on the circuit board to form a solder resist layer, and its main function is to prevent physical disconnection of the conductor circuit, short circuit in the soldering process, and solder waste. Therefore, the quality and coating effect of green oil directly affect the quality and performance of the circuit board. However, in the traditional circuit board manufacturing process, green oil coating usually uses a single printing machine for batch printing. It is difficult for a single printing machine to ensure the printing quality of each circuit board, so multiple printings are required, resulting in low work efficiency.

[0003] In view of the above problems, the utility model proposes a green oil two-machine continuous printing production device for circuit board production. Content of the Utility Model

[0004] The purpose of the utility model is to provide a green oil two-machine continuous printing production device for circuit board production. A conveying frame is installed at the upper end of the installation base frame. A printing machine A is arranged at one end of the conveying frame, and a printing machine B is arranged at the end of the conveying frame far from the printing machine A. A first correction component and a second correction component are installed at the upper end of the installation base frame. The printing machine A and the printing machine B are both arranged relatively with respect to the center of the conveying frame, thus solving the problems in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A green oil two-machine continuous printing production device for circuit board production, including an installation base frame. A conveying frame is installed at the upper end of the installation base frame. A printing machine A is arranged at one end of the conveying frame, and a printing machine B is arranged at the end of the conveying frame far from the printing machine A. A first correction component and a second correction component are installed at the upper end of the installation base frame. The first correction component and the second correction component are symmetrically distributed about the center of the conveying frame.

[0006] Furthermore, the printing machine A and the printing machine B are both arranged relatively with respect to the center of the conveying frame.

[0007] Furthermore, the first correction component and the second correction component have the same composition structure.

[0008] Further, the first correction component includes a rotating member rotatably mounted on the mounting chassis. A motor is fixedly connected to the lower end of the rotating member. A middle connection block is fixedly connected to the end of the rotating member away from the motor. An elastic sheet is fixedly connected to one side of the middle connection block. A correction rod is fixedly connected to the end of the elastic sheet away from the middle connection block.

[0009] Further, the elastic sheet is a member made of rubber material.

[0010] Further, a push rod body is pivotally connected to the outer wall of the elastic sheet. An opening is formed in the outer wall of the middle connection block. A sliding block is slidably connected to the inner wall of the opening. The push rod body is pivotally connected to the sliding block.

[0011] Further, an elastic element is fixedly connected to one end of the sliding block. The end of the elastic element away from the sliding block is fixedly connected to the bottom of the opening.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0019] 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 work shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 4 , in order to solve the problem that in the traditional circuit board manufacturing process, green oil coating usually uses a single printing press for batch printing. It is difficult for a single printing press to ensure the printing quality of each circuit board, so multiple printings are required, resulting in low work efficiency. The following preferred technical solutions are provided:

[0021] A green oil two-machine continuous printing production device for circuit boards includes an installation chassis 1. A conveyor frame 2 is installed at the upper end of the installation chassis 1. A printing press A 3 is arranged at one end of the conveyor frame 2. A printing press B 4 is arranged at the end of the conveyor frame 2 away from the printing press A 3. A first correction assembly 5 and a second correction assembly 6 are installed at the upper end of the installation chassis 1. The first correction assembly 5 and the second correction assembly 6 are symmetrically distributed about the center of the conveyor frame 2. The printing press A 3 and the printing press B 4 are both relatively arranged about the center of the conveyor frame 2. The first correction assembly 5 and the second correction assembly 6 have the same composition structure.

[0022] The first correction assembly 5 includes a rotating part 51 rotatably installed on the installation chassis 1. A motor 52 is fixedly connected to the lower end of the rotating part 51. An intermediate connection block 53 is fixedly connected to the end of the rotating part 51 away from the motor 52. An elastic sheet 54 is fixedly connected to one side of the intermediate connection block 53. A correction rod 55 is fixedly connected to the end of the elastic sheet 54 away from the intermediate connection block 53. The elastic sheet 54 is a component made of rubber material. A pusher body 56 is axially connected to the outer wall of the elastic sheet 54. An opening is formed in the outer wall of the intermediate connection block 53. A sliding block 57 is slidably connected to the inner wall of the opening. The pusher body 56 is axially connected to the sliding block 57. An elastic element 58 is fixedly connected to one end of the sliding block 57. The end of the elastic element 58 away from the sliding block 57 is fixedly connected to the bottom of the opening.

[0023] Specifically, when applying solder mask to the circuit board, first, the circuit board is preliminarily coated with solder mask by the printing machine A3. Then, the preliminarily coated circuit board is removed, and a new circuit board is placed in the printing machine A3. The preliminarily coated circuit board is placed on the conveying rack 2 for conveying. The first correction component 5 and the second correction component 6 are used to correct the position of the conveyed circuit board. Subsequently, the preliminarily coated circuit board will be conveyed to the printing machine B4 for solder mask coating again, ensuring that the printing quality of each circuit board is exactly the same. The subsequent circuit boards are processed in the same way, ensuring the printing quality of each circuit board and solving the problem that in the traditional circuit board manufacturing process, solder mask coating usually uses a single printing machine for batch printing. It is difficult for a single printing machine to ensure the printing quality of each circuit board, so multiple printings are required, resulting in low work efficiency.

[0024] When the first correction component 5 and the second correction component 6 correct the position of the conveyed circuit board, the motor 52 drives the rotating member 51 to swing back and forth, so that the correction rod 55 continuously pushes towards the center position. Whenever the circuit board is offset, it will collide with the correction rod 55. The correction rod 55 bends through the elastic piece 54, driving the push rod body 56 to squeeze the sliding block 57, so that the sliding block 57 squeezes the elastic element 58. At this time, by the reaction of the elastic element 58 and the elasticity of the elastic piece 54, the correction rod 55 is driven to quickly reset, thereby pushing the correction rod 55 to achieve the purpose of correction.

[0025] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.
