Technical Field

[0001] The utility model relates to the field of chip mounters, and more specifically, to a calibration device for SMT chip mounting processing. Background Technique

[0002] An SMT chip mounter is a machine for a series of technological processes based on a PCB printed circuit board. SMT is surface mounting technology (surface mount technology), which is the most popular technology and process in the electronic assembly industry. When processing SMT chips in large quantities, a calibration device is required. The calibration device can guide and align the conveyed materials to ensure that the conveyed materials can maintain a unified center line and position, facilitating subsequent processing and use.

[0003] However, most of the current calibration devices for SMT chip mounting processing have the following problems:

[0004] The existing calibration devices for SMT chip mounting processing can mostly only calibrate SMT chips of the same size during the calibration of SMT chip mounting. Since SMT chips come in different sizes and models, it is inconvenient to adjust and calibrate SMT chips of different sizes. At the same time, during processing, most SMT chips are exposed. When processing, dust and impurities are likely to adhere to the surface of the SMT chips. If there is some dust and impurities at the position to be processed, it is likely to affect the processing quality and effect, and it is inconvenient to conveniently clean and collect the dust on the SMT chips.

[0005] Therefore, we make improvements and propose a calibration device for SMT chip mounting processing. Content of the Utility Model

[0033] Example 2:

[0034] The solution in Example 1 will be further introduced below in combination with the specific working mode. See the following description for details:

[0035] As Figure 3 shown, as a preferred embodiment, on the basis of the above method, further, the threaded sleeves 2 are symmetrically distributed on the left and right sides of the protective housing 1. The threaded sleeves 2 and the calibration blocks 5 are in one-to-one correspondence through the threaded rods 4, which can ensure the cooperation of the two calibration blocks 5, be able to guide and straighten the conveyed materials for calibration, and improve the subsequent processing effect.

[0036] As Figure 3 shown, as a preferred embodiment, on the basis of the above method, further, the side end face of the calibration block 5 is inclined, and the bottom end face of the support plate 9 is in contact with the bottom end face of the conveyor belt 8, which can ensure that the inclined surface of the calibration block 5 can be used to guide the materials.

[0037] As Figure 5 shown, as a preferred embodiment, on the basis of the above method, further, the air suction pipes 17 are equidistantly distributed on the air distribution box 16, and the height of the bottom end face of the air suction pipes 17 is greater than the height of the bottom end face of the soft brush 19, which can ensure that multiple air suction pipes 17 can improve the dust and impurity suction efficiency.

[0038] As Figure 5As shown, as a preferred embodiment, on the basis of the above method, further, the installation boxes 20 are symmetrically distributed on the left and right sides of the air distribution box 16. The installation boxes 20 and the clamping rods 23 correspond to each other through the limiting plates 22, which can ensure the cooperation of the clamping rods 23 on both sides and can clamp and fix the support frame 18.

[0039] As Figure 5 shown, as a preferred embodiment, on the basis of the above method, further, a pull plate 24 is fixedly connected to the limiting plate 22, and a protective cover plate 25 is bolted to the protective housing 1. The side end face of the limiting plate 22 is attached to the inner side face of the installation box 20, which can ensure that when the limiting plate 22 moves, it can move smoothly through the support of the inner side face of the installation box 20.

[0040] Specifically, when the calibration device for SMT chip mounter is in use: combined with Figures 1-5 , when processing SMT chips, if the SMT chips are different in material model and size from the previous batch, the turntable 3 can be rotated to drive the threaded sleeve 2 to operate. When the threaded sleeve 2 rotates, it can push the threaded rod 4 to move. When the threaded rod 4 moves, it can drive the calibration block 5 to move simultaneously. When the calibration block 5 moves, it moves smoothly under the sliding support of the two guide rods 6 in the protective box 7, avoiding the situation of shaking and deviation when the calibration block 5 moves, and can adjust the distance between the two calibration blocks 5 according to the size of the SMT chip. When the conveyor belt 8 conveys the SMT chip, the SMT chip can be calibrated and straightened through the inclined surfaces of the two calibration blocks 5, which is convenient to be conveyed to the subsequent processing equipment, improving the calibration use effect.

[0041] When cleaning the dust and impurities on the conveyed SMT chip, the hydraulic cylinder 15 is opened to drive the air distribution box 16 to move downward. When the SMT chip moves, the soft brush 19 on the air distribution box 16 can clean the dust on the surface. At the same time, the pump body 13 is opened. The pump body 13 can suck and collect the cleaned dust through the multiple suction pipes 17 on the air distribution box 16, and convey the dust and impurities to the waste box 10 through the conveying hose 14 for centralized collection and treatment. At the same time, the protective net 12 on the sealing cover plate 11 can prevent the dust and impurities from damaging the pump body 13, and can avoid the dust and impurities from affecting the processing quality of the SMT chip. When it is necessary to clean the dust in the waste box 10, the sealing cover plate 11 on the waste box 10 can be opened to clean and collect the internal dust and impurities.

[0042] If the soft brush 19 is worn or otherwise damaged during long-term use and needs to be replaced, the protective cover plate 25 on the protective housing 1 can be opened. Then, the pull plates 24 on both sides of the mounting box 20 are squeezed. When the pull plates 24 drive the limit plates 22 to move, the limit plates 22 can squeeze the springs 21. At the same time, the limit plates 22 can drive the latch rods 23 to disengage from the support frame 18. When the support frame 18 is unobstructed, the support frame 18 and the soft brush 19 can be taken out for replacement. After the replacement and reinstallation, the pull plates 24 on both sides can be released. Under the push of the spring 21, the limit plates 22 and the latch rods 23 are reset. The latch rods 23 can be engaged in the support frame 18 for limit fixation to prevent the soft brush 19 from falling off during use. Moreover, when the conveyor belt 8 conveys materials, with the support of the support plate 9, the conveyor belt 8 can be prevented from sagging or the like.
