Description

Consumables management and control system and method for printing machine fixture

The invention relates to a consumable material management and control system and method thereof, in particular to a consumable material management and control system and method for printing machine fixtures.

In recent years, with the popularization and vigorous development of solder paste printing technology, how to further improve the printing quality and reduce the loss of consumables has become one of the problems that manufacturers are eager to solve.

Generally speaking, the so-called solder paste printing technology refers to the technology that needs to accurately repeatedly apply solder paste to a specific position of the printed circuit board while controlling the amount of solder paste. To this end, the printing of solder paste must be controlled using a so-called stencil, which is matched to the printed circuit board and hollowed out where tinning is required. If the solder paste offsets the printing position too much, it will not be able to achieve the purpose of component welding, and unexpected quality problems may occur, and the amount of solder paste may cause short circuit (Short) or non-wetting (Non-wetting). . In the actual solder paste printing operation, after the steel plate is aligned with the printed circuit board, the solder paste is filled into all the openings of the steel plate with a scraper, and then the steel plate is lifted to leave the solder paste after the solder paste printing. From the previous description, it can be known that there are many factors that affect the printing quality that need to be considered and controlled during the entire solder paste printing process, such as: the type, angle, pressure, speed of the scraper, and the opening, cleaning, and removal of the steel plate. die speed etc. At the same time, the quality of the solder paste itself also needs to be strictly controlled, including the management of low-temperature storage, warm-up time, stirring time, time of opening and putting into use, etc. Solder paste with inconsistent quality will be banned from use. However, due to the lack of effective and objective management and control of these fixtures (such as steel plates) and consumables (such as solder paste), defective or scrap products with poor printing quality are produced during the solder paste printing process, which not only affects production It also causes waste of consumables, so there are problems of poor printing quality and high consumption of consumables.

As shown in "Figure 4", "Figure 4" is a schematic diagram of the application of the present invention to monitor the remaining life of fixtures and consumables. As mentioned above, the display element 124 displays the remaining life of the jig and the remaining life of the consumable. In actual implementation, as shown in "Fig. 4", a monitoring window 400 can be displayed on the display element 124, which can include: a fixture consumable display block 410, a remaining life display block 420, and a graphical display area Block 430 is used to display the name of the consumable fixture, the remaining life, and the graphical representation of the remaining life, respectively. It can be clearly seen from the figure that when the consumable is "solder paste", the remaining life of the consumable is "1335 minutes", and the ratio of the "remaining life of the consumable" to the "life of the consumable" can be seen in the graphical display block 430 , where the dots represent the proportion of the remaining life of the consumables. Similarly, when the jig is a "steel plate", the remaining life of the jig is "325 minutes", and the ratio of the "remaining life of the jig" to the "life of the jig" can be seen in the graphical display block 430, where The dot part represents the proportion of "remaining tool life".

To sum up, it can be seen that the difference between the present invention and the prior art lies in scanning the jigs and consumables through the control host to obtain the corresponding life of the jigs and consumables, and continuously calculating the use status of the jigs and consumables, and then according to the investment The usage status, fixture life and consumable life calculate the remaining life of the fixture and the remaining life of the consumable, and when one of the two is lower than the threshold value, a stop signal is generated to be sent to the programmable logic controller of the track device, so that it can be The programmable logic controller controls the track device to stop moving, avoiding the use of poor-quality jigs or consumables for printing. This technical means can solve the problems existing in the previous technology, thereby achieving a technology that improves printing quality and reduces consumable consumption. effect.
