Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic manufacturing technology, specifically to a PCB board printing base. Background Technology
[0002] Circuit board printing is a crucial step in the production process. With the diversification and miniaturization of electronic products, there is often a need to process circuit boards of the same size but different shapes. Traditional printing equipment and bases are often designed for specific shapes or a limited number of shapes. For example, Chinese Patent No. CN205631672U discloses a vacuum base for a printing machine. It uses a vacuum base in conjunction with a printing base to hold the PCB board in place by vacuum, which is more stable and durable than ejector pins. However, when changing to a new model, it is necessary to find a supplier to order a complete set of printing bases, which is difficult to meet such flexible and ever-changing production requirements. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a PCB board printing base that can be applied to circuit boards of the same size but different shapes.
[0004] The technical solution of this utility model is as follows:
[0005] A PCB board printing base includes a base, a support seat on the base, support blocks on both sides of the base, a sealing ring on the upper surface of the base, positioning posts between the support blocks, a number of air intake holes in the middle of the base, positioning holes on both sides of the support seat, screw holes I on the positioning holes, and a number of support posts in the middle of the support seat.
[0006] Preferably, the positioning post is provided with screw holes II.
[0007] Preferably, the base has a vacuum chamber inside, and vacuum inlets are provided on both sides of the vacuum chamber.
[0008] Preferably, the support column is provided with a vacuum hole.
[0009] Preferably, the sealing ring is fixed between the base and the support.
[0010] Preferably, the positioning post and the positioning hole are nested together.
[0011] Compared with the prior art, this utility model has the following advantages:
[0012] 1. High versatility: It can adapt to the printing needs of circuit boards of different shapes but the same size, reducing the dependence on various special printing bases and improving the utilization rate of the equipment.
[0013] 2. Cost savings: By using circuit boards of the same size but different shapes, it is not necessary to build the entire printing base. Only the corresponding clearance support base needs to be built, which reduces the cost of building fixtures.
[0014] 3. High flexibility: It can easily replace different types of printing tools to meet various printing process requirements and adapt to the production pace of rapid updates in electronic products.
[0015] 4. Easy to maintain: The structure is reasonably designed and each component is easy to disassemble and replace, which reduces maintenance costs and difficulty.
[0016] 5. High precision: Compared with traditional fully enclosed and semi-enclosed bases, it can reduce the impact of base flatness on printing accuracy. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0024] Example 1
[0025] like Figures 1-4 As shown, this embodiment provides a PCB board printing base 1, including a base 1, a support seat 2 on the base 1, support blocks 3 on both sides of the base 1, a sealing ring 4 on the upper surface of the base 1, positioning posts 5 between the support blocks 3, several air suction holes in the middle of the base 1, positioning holes 7 on both sides of the support seat 2, screw holes 18 on the positioning holes 7, and several support posts 9 in the middle of the support seat 2. The support blocks 3 effectively fix the support seat 2, further securing the circuit board, while the support posts 9 facilitate the fixing of the circuit board.
[0026] Preferably, the positioning post 5 is provided with screw hole II10. By providing screw hole II10 to cooperate with screw hole I8, it is convenient to fix the base 1 and the support 2, which is beneficial for fixing the printed circuit board.
[0027] Preferably, the base 1 has a vacuum chamber 11 inside, and vacuum inlets 12 are provided on both sides of the vacuum chamber 11. By setting the vacuum chamber 11 and the suction port, air is drawn in from the vacuum inlets 12, and the base 1 below and the vacuum chamber 11 below perform a vacuuming effect on the support base 2 to achieve the fixing effect of the PCB board. The sealing ring 4 above ensures the vacuum state of the support base 1.
[0028] Preferably, the support column 9 is provided with a vacuum hole 136. The support column 9 provides good support for the PCB board, and the vacuum hole 136 in the middle of the support column 9 provides stability for the PCB during operation.
[0029] Preferably, the sealing ring 4 is fixed between the base 1 and the support 2. The sealing ring 4 ensures the vacuum state of the support 2.
[0030] Preferably, the positioning post 5 and the positioning hole 7 are nested together. By setting the positioning post 5 and the positioning hole 7 in a nested manner, the accuracy and stability of the installation of the support base 2 and the base 1 are ensured.
[0031] Preferably, the support columns 9 are arranged in several ways. By setting multiple arrangements of the support columns 9, the printing requirements of circuit boards of the same size but different shapes can be met.
[0032] Working principle:
[0033] During use, place the fixed part of base 1 on a stable and level workbench. Use a high-precision level to measure the levelness of the positioning platform on base 1, ensuring the levelness error is within ±0.02mm, thus providing a stable foundation for subsequent operations. Check the thread condition of the threaded holes around the fixed part of base 1 and in the middle, ensuring the threads are undamaged and free of debris. Clean the inside of the threaded holes; use a compressed air spray gun to blow away any dust or debris, ensuring the cleanliness and smoothness of the threaded holes for subsequent installation of the clearance support base 1. Based on the specific IC layout of the PCB to be printed, select a suitable set from the various pre-designed and manufactured clearance support base 2 modules. During the selection process, carefully check the position, height, and shape of the support column 9 to ensure its compatibility with the IC on the PCB, ensuring that the support column 9 can accurately provide clearance space for the IC and avoid any damage to the IC during the printing process. After placing the PCB on the support base 2, turn on the vacuum and check the sealing between the support base 1 and base 2. Use a high-precision level to measure the levelness of the PCB to ensure it meets the operating accuracy, thus ensuring the accuracy of subsequent printing operations.
