Description

Technical Field

[0001] The utility model relates to the technical field of a double-table CCD automatic alignment hole plugging machine, in particular to a double-table CCD automatic alignment hole plugging machine. Background Art

[0002] At present, there are four types of vacuum screen printers for printed circuit boards on the market. The first type of vacuum screen printer (single-table screen printer) has only one table and one screen frame, see Chinese patent numbers CN1277673C and CN105034553B. The second type of vacuum screen printer (double-table screen printer arranged up and down) is composed of two upper and lower tables that alternately go in and out and a screen frame, see Chinese patent number CN111267471A. The third type of vacuum screen printer (double-table screen printer arranged left and right) is composed of a screen frame and two small tables on a large table, see Chinese patent numbers CN111873611B and CN113085350B, the fourth type of vacuum screen printer (double-table screen printer arranged left and right) is composed of two screen frames and two small tables, see Chinese patent numbers CN116587723A and CN219822830U;

[0003] For the first type of vacuum screen printing machine, the production cycle of the first type of vacuum screen printing machine is slower than that of the double-table screen printing machine;

[0004] For the second type of vacuum screen printer, since one screen frame corresponds to the upper and lower tables, although it can shorten the printing cycle, it can only print one side of the PCB. If you want to print the front and back sides at the same time, you need two devices;

[0005] For the third type of vacuum screen printer, since the table is composed of two small tables on a large table, one machine can print both the front and back sides of the PCB at the same time. However, it requires an extra-large screen frame, and the manufacturing process of the large screen frame is more complicated than that of the small screen frame;

[0006] For the fourth type of vacuum screen printing machine, since two screen frames are required, the workers spend too much time aligning the screen frames with the circuit boards, which is twice the time required for one screen frame. The workers need to concentrate on the alignment for a long time, which increases the workers' labor intensity. Especially when producing small batches of circuit boards, the screen frames must be changed and aligned many times a day, which makes the workers overworked. In addition, the workers' skill level is high, and the different proficiency of the workers will seriously affect the changeover and debugging time. Utility Model Content

[0053] S1: The worker inserts the right screen 11a into the frame 4, presses the right screen lock button, and the six-point clamping cylinder 43 clamps the right screen 11a. The worker then inserts the left screen 11b into the frame 4, presses the left screen lock button, and the six-point clamping cylinder 43 clamps the left screen 11b. The worker installs a scraper 47 and an ink-covering knife 48 of appropriate size, pours ink into the right ink storage box 41a and the left ink storage box 41b, closes the main compartment rear door 13, presses the main compartment rear door lock button, and rotates the clamping cylinder 12 to lock the two main compartment rear doors 13 together.

The camera 143a is manually moved to the top of the ink dot that needs to be aligned. The two cameras 143a are placed diagonally, and the infrared indicator light The red light dot 146a overlaps with the ink dot, which is directly above. The worker observes the right CCD display 8a to confirm that the ink dot position on the image is in the center of the screen. The worker presses the button on the locking cylinder control box 147a again to lock the camera Y-axis locking cylinder 141a and the camera X-axis locking cylinder 142a. The visual software system is used to calibrate the ink dot position and set it as the reference point. The cover opening button is pressed to open the right cover 2a.
