Description

Technical Field

[0001] This utility model belongs to the field of printed circuit board manufacturing technology, and in particular relates to a PCB screen developing table. Background Technology

[0002] In the manufacturing process of printed circuit boards (PCBs), the developing process is a crucial step that directly affects the final quality and performance of the circuit board.

[0003] According to a public disclosure (publication number: CN201774751U), a PCB screen developing table includes: a lighting tube, a glass baffle, a slot, and a support table. The overall structure is welded from stainless steel plates. A fixing slot is provided on the support table to easily fix the screen and prevent it from sliding during washing. A glass baffle with good light transmission is built in, and a fluorescent tube is embedded behind the glass baffle. Light can shine through the glass to promptly detect problems on the screen. This utility model effectively avoids the problem of scrapping the screen due to irregular lines caused by uneven water washing pressure.

[0004] The aforementioned application, which uses a combination of a built-in transparent glass baffle and a fluorescent tube, can assist in observing screen printing issues, but suffers from low development efficiency and insufficient light uniformity. Specifically, the scattered light from the fluorescent tube is difficult to focus precisely on the working area of ​​the screen printing plate, resulting in insufficient development in the edge areas. Therefore, we propose a PCB screen printing plate developing station. Utility Model Content

[0005] The purpose of this invention is to provide a PCB screen developing table that solves the existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a PCB screen developing table, including a support body, a box body fixedly connected to the top of the support body, a control panel provided on the side of the box body, a placement plate fixedly connected to the inner wall of the box body, and a focusing developing device provided on the side of the box body.

[0007] The focusing developing device includes a focusing cover, which is fixedly connected to the side of the housing. A developing module is provided on the side of the focusing cover. A power cord is provided on the top of the developing module. A terminal block is provided at the end of the power cord away from the developing module. A locking post is fixedly connected to the side of the housing. A locking plate is provided on the circumferential surface of the locking post. A diffuser plate is provided on the inner side of the housing.

[0008] Furthermore, the side of the terminal block is fixedly connected to the side of the enclosure, which helps to securely fix the terminal block to the side of the enclosure, ensuring the stability and safety of the power connection and avoiding circuit failures or signal interruptions caused by unstable connections.

[0009] Furthermore, the side cross-section of the light-concentrating mask is designed as a triangle, which helps the light-concentrating mask to focus and guide the light more effectively, so that the PCB screen can receive more concentrated and uniform illumination, thereby improving the development effect and accuracy.

[0010] Furthermore, the side cross-section of the diffuser is set to be arc-shaped, and the condenser is connected to the inner side of the housing. This helps the diffuser to evenly disperse the light focused by the condenser, avoiding local light that is too strong or too weak, and further improving the uniformity and quality of development.

[0011] Furthermore, the side of the card plate abuts against the side of the diffuser plate, which helps the card plate to provide stable support and positioning for the diffuser plate, preventing the diffuser plate from shifting or shaking during use, and ensuring the stability and reliability of the diffuser effect.

[0012] Furthermore, an adjustable viewing device is provided on the inner top of the box body. The adjustable viewing device includes an upper limit plate, which is fixedly connected to the inner top of the box body. A through hole is opened on the top of the placement plate, and a snap-fit ​​post is provided inside the through hole. A lower limit plate is provided on the top of the placement plate. This facilitates the flexible adjustment of the adjustable viewing device, and the operator can precisely control the intensity and angle of the light according to actual needs.

[0013] Furthermore, the number of through holes is set to several and arranged in a linear array along the top of the placement plate. This allows for flexible adjustment of the installation position of the snap-fit ​​posts according to different PCB screen sizes and development requirements, thereby achieving precise control of the distance between the lower limit plate and the upper limit plate.

[0014] Furthermore, the circumferential surface of the locking post abuts against the side surface of the lower limiting plate, which helps the locking post to provide stable support for the lower limiting plate.

[0015] This utility model has the following beneficial effects: This invention achieves efficient and uniform development of PCB screens through the coordinated operation of components such as the condenser mask, developing module, and power cord in a condenser developing device. The triangular side section design of the condenser mask allows light to be precisely focused and guided onto the PCB screen, ensuring the concentration and uniformity of illumination, thereby improving the accuracy and effect of development and enhancing the quality of development. The stable connection of the power cord and the fixed design of the terminal blocks ensure a stable and reliable power supply throughout the entire development process, avoiding development interruptions or quality issues caused by power problems.

[0016] This invention achieves flexible adjustment of light intensity and angle through the cooperation of components such as the upper limit plate, through holes, and snap-fit ​​posts in the adjustable light viewing device. The fixed connection between the upper limit plate and the top of the inner side of the housing provides a stable support foundation for the entire adjustable light viewing device. The multiple linear array of through holes on the placement plate, together with the use of snap-fit ​​posts, allows the lower limit plate to be precisely adjusted in position according to the size of different PCB screens and development requirements.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 As shown, this utility model is a PCB screen developing table, including a support body 1, a box body 2 fixedly connected to the top of the support body 1, a control panel 3 provided on the side of the box body 2, a placement plate 4 fixedly connected to the inner wall of the box body 2, and a focusing developing device 5 provided on the side of the box body 2.

[0023] The developing device 5 includes a condenser 501, which is fixedly connected to the side of the housing 2. A developing module 502 is provided on the side of the condenser 501. A power cord 503 is provided on the top of the developing module 502. A terminal block 504 is provided at the end of the power cord 503 away from the developing module 502. A locking post 505 is fixedly connected to the side of the housing 2. A locking plate 506 is provided on the circumferential surface of the locking post 505. A diffuser plate 507 is provided on the inner side of the housing 2.

[0024] As shown in the figure, the side of the terminal block 504 is fixedly connected to the side of the housing 2. This helps to securely fix the terminal block 504 to the side of the housing 2, ensuring the stability and safety of the power connection and avoiding circuit failures or signal interruptions caused by unstable connections.

[0025] As shown in the figure, the side cross-section of the condenser mask 501 is set as a triangle, which helps the condenser mask 501 to focus and guide the light more effectively, so that the PCB screen can receive more concentrated and uniform illumination, thereby improving the development effect and accuracy.

[0026] As shown in the figure, the side cross-section of the diffuser plate 507 is set to be arc-shaped, and the condenser hood 501 penetrates the inner side of the housing 2. This is beneficial for the diffuser plate 507 to evenly disperse the light focused by the condenser hood 501, avoiding the situation of excessively strong or weak local illumination, and further improving the uniformity and quality of development.

[0027] As shown in the figure, the side of the card plate 506 abuts against the side of the diffuser plate 507. This helps the card plate 506 to provide stable support and positioning for the diffuser plate 507, preventing the diffuser plate 507 from shifting or shaking during use, and ensuring the stability and reliability of the diffused light effect.

[0028] As shown in the figure, an adjustable viewing device 6 is provided on the top inner side of the housing 2. The adjustable viewing device 6 includes an upper limit plate 601, which is fixedly connected to the top inner side of the housing 2. A through hole 602 is provided on the top of the placement plate 4, and a snap-fit ​​post 603 is provided inside the through hole 602. A lower limit plate 604 is provided on the top of the placement plate 4. This facilitates the flexible adjustment of the adjustable viewing device 6, and the operator can accurately control the intensity and angle of the light according to actual needs.

[0029] As shown in the figure, there are several through holes 602, which are arranged in a linear array along the top of the placement plate 4. This allows for flexible adjustment of the installation position of the snap-fit ​​posts 603 according to different PCB screen sizes and development requirements, thereby enabling precise control of the distance between the lower limit plate 604 and the upper limit plate 601.

[0030] As shown in the figure, the circumferential surface of the snap-fit ​​post 603 abuts against the side of the lower limit plate 604, which helps the snap-fit ​​post 603 to provide stable support for the lower limit plate 604.

[0031] One specific application of this embodiment is as follows: After the operator securely connects terminal 504 to the external power supply, they start the equipment via control panel 3. At this time, the developing module 502 begins to work, and the power cord 503 stably transmits current to the developing module 502. The condenser 501, with its triangular side-section design, precisely focuses and guides the light into the housing 2. After passing through the condenser 501 which penetrates the inner side of the housing 2, the light illuminates the diffuser 507, which has an arc-shaped side section. The diffuser 507 evenly disperses the concentrated light, avoiding uneven local illumination. The retaining plate 506 tightly abuts against the side of the diffuser 507, ensuring the diffuser 507 is in a stable position. Due to the vibration caused by the operation of the equipment, the operator can flexibly adjust the installation position of the locking post 603 by using several through holes 602 on the top linear array of the placement plate 4 according to the different specifications of PCB screen size and development requirements. After the locking post 603 is installed in place, its circumferential surface abuts against the side of the lower limit plate 604, forming a stable support for the lower limit plate 604. In conjunction with the upper limit plate 601 fixed on the top of the inner side of the housing 2, the distance between the lower limit plate 604 and the upper limit plate 601 can be precisely controlled. This allows the adjustable light viewing device 6 to accurately control the intensity and angle of the light according to actual needs, providing a suitable development lighting environment for the PCB screen and ultimately completing a high-quality development operation.
