Description

Technical Field

[0001] The present invention relates to a consumables management and control system and method thereof, in particular to a consumables management and control system and method thereof for a printing press fixture. Background Art

[0002] In recent years, with the popularization and vigorous development of solder paste printing technology, how to further improve printing quality and reduce consumables loss has become one of the problems that manufacturers are eager to solve.

[0003] Generally speaking, the so-called solder paste printing technology refers to the technology that requires the solder paste to be repeatedly applied to specific positions of the printed circuit board accurately and the amount of solder paste to be controlled at the same time. To this end, the so-called stencil must be used to control the printing of the solder paste. This stencil matches the printed circuit board and is hollowed out at the position where the tin is required. If the solder paste deviates too much from the printing position, it will not be able to achieve the purpose of soldering parts, and unexpected quality problems may occur. The amount of solder paste may cause solder short circuits (Short) or non-wetting and other defects. In the actual solder paste printing operation, after the stencil and the printed circuit board are aligned, a scraper is used to fill the solder paste into all the openings of the stencil, and then the stencil is lifted up after the solder paste is printed to leave the solder paste. From the previous description, it can be seen that in the entire solder paste printing process, there are many factors that affect the printing quality that need to be considered and controlled, such as: the type, angle, pressure, speed of the scraper, and the opening, cleaning, and demolding speed of the stencil. At the same time, the quality of the solder paste itself also needs to be strictly controlled, including the management of low-temperature storage, warming time, stirring time, opening time, etc. Solder paste that does not meet the quality standards will be prohibited from use. However, due to the lack of effective and objective management and control of these jigs (such as steel plates) and consumables (such as solder paste), the solder paste printing process produces defective or scrapped products with poor printing quality, which not only affects the production quality, but also causes waste of consumables, resulting in poor printing quality and excessive consumable loss.

[0004] In summary, it can be seen that the prior art has long had problems with poor printing quality and excessive consumables loss, so it is necessary to propose improved technical means to solve this problem. Summary of the invention

[0006] First, the present invention discloses a consumables control system for a printer jig, which is applied to a track device at the front end of a printer. The system includes a remote host and a control host. The remote host is used to store the jig number and its corresponding jig life, as well as the consumable number and its corresponding consumable life; the control host is electrically connected to a programmable logic controller of the track device, which includes a network module, a scanner, a processing unit, and a display element. Among them, the network module is used to connect the control host and the remote host to each other and transmit data; the scanner is used to scan the fixture and consumables to obtain the corresponding fixture number and consumable number; the processing unit is connected to the network module and the scanner, and is used to continuously calculate the use status of the fixture and consumables, and query the remote host for the corresponding fixture life and consumable life according to the read fixture number and consumable number, and calculate the corresponding fixture remaining life and consumable remaining life according to the use status, fixture life and consumable life. When the fixture remaining life or the consumable remaining life is lower than the threshold value, a stop signal is generated to be transmitted to the programmable logic controller, so that the programmable logic controller controls the track device to stop moving; and the display element is electrically connected to the processing unit to output the calculated fixture remaining life and consumable remaining life.

[0008] The system and method disclosed in the present invention are as described above. The difference from the prior art is that the present invention uses a control host to scan the jig and consumables to obtain the corresponding jig life and consumable life, and continuously calculates the use status of the jig and consumables, and then calculates the remaining jig life and consumable life based on the use status, jig life and consumable life, and when one of the two is lower than a threshold value, generates a stop signal to transmit to the programmable logic controller of the track device, so that the programmable logic controller controls the track device to stop moving, thereby avoiding the use of poor quality jigs or consumables for printing.

DETAILED DESCRIPTION

[0038] The following will describe the implementation methods of the present invention in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0039] Please read first Figure 1 , Figure 1This is a system block diagram of the consumables control system for the jig of the printing press of the present invention, which is applied to the track device 100 at the front end of the printing press. This system includes: a remote host 110 and a control host 120. Among them, the remote host 110 is used to store the jig number and its corresponding jig life, and to store the consumable number and its corresponding consumable life. In actual implementation, the jig life and consumable life both include available time and available times or either of them. The available time and available times are allowed to be pre-set by logging into the remote host 110, or directly receive the usage parameters corresponding to the jig and consumables from the jig consumables supply host as the available time and available times. It should be supplemented that the remote host 110 may include a manufacturing execution system (Manufacture Executive System, MES) and a production maintenance system (Total Productive Maintenance, TPM).

[0040] The control host 120 is electrically connected to the programmable logic controller 101 of the track device 100, and the control host 120 includes: a network module 121, a scanner 122, a processing unit 123 and a display element 124. The network module 121 is used to connect the control host 120 and the remote host 110 to each other and transmit data. In actual implementation, the network module 121 can use wired or wireless transmission. For example, for wired transmission, it can use copper wires, coaxial cables, optical fibers, twisted pairs or the like as transmission media; for example, for wireless transmission, it can use radio waves, microwaves, infrared rays, lasers or the like as transmission media.

[0041] The scanner 122 is used to scan the jig and consumables to obtain the corresponding jig number and consumable number. In actual implementation, the scanner 122 can obtain the corresponding jig number and consumable number by scanning the barcode of the jig itself and the consumable itself, such as: one-dimensional barcode, two-dimensional barcode (i.e.: QR code), etc. In addition, the scanner 122 can also obtain the jig number and consumable number by radio frequency identification technology (RFID).

[0042] The processing unit 123 is connected to the network module 121 and the scanner 122, and is used to continuously calculate the use status of the fixture and the consumables, and query the remote host 110 for the corresponding fixture life and consumable life according to the read fixture number and consumable number, and calculate the corresponding fixture remaining life and consumable remaining life according to the use status, fixture life and consumable life. When the fixture remaining life or the consumable remaining life is lower than the threshold value, a stop signal is generated to be transmitted to the programmable logic controller 101, so that the programmable logic controller 101 controls the track device 100 to stop moving. In actual implementation, the processing unit 123 can be a microcontroller unit (MCU), a microprocessor (Microprocessor), a central processing unit (CPU), a system on a chip (System ona Chip, SoC), etc., to execute instructions to calculate the remaining life of the fixture and the remaining life of the consumables, and generate a stop signal when either of them is lower than the threshold value. It should be particularly noted that when the stop signal is generated, at least one of the tower light, buzzer and speaker electrically connected to the programmable logic controller 101 can be enabled to warn, and a warning message is generated to be output through the display element 124. In addition, the use status can include the use time and the number of uses or either of them. The control host 120 will continuously detect the use time and the number of uses of the fixture and consumables to accumulate the corresponding use time and the number of uses respectively.

[0043] The display element 124 is electrically connected to the processing unit 123 to output the calculated remaining life of the fixture and the remaining life of the consumables. In actual implementation, the display element 124 can be a screen, a touch screen, an electronic paper, etc. The method of displaying the remaining life of the fixture and the remaining life of the consumables by the display element 124 will be described later in conjunction with the drawings in the specification.

[0044] It should be particularly noted that in actual implementation, the modules described in the present invention can be implemented in various ways, including software, hardware or any combination thereof. For example, in some embodiments, each module can be implemented using software and hardware or one of them. In addition, the present invention can also be partially or completely implemented based on hardware. For example, one or more modules in the system can be implemented by integrated circuit chips, system on chip (System on Chip, SoC), complex programmable logic device (Complex Programmable Logic Device, CPLD), field programmable logic gate array (Field Programmable Gate Array, FPGA), etc. The present invention can be a system, method and / or computer program.

[0045] See also Figure 2 , Figure 2 The method flow chart of the consumables control method of the printer fixture of the present invention is applied to the track device at the front end of the printer, and the steps include: providing a control host, the control host includes a network module, a scanner, a processing unit and a display element, and is electrically connected to the programmable logic controller that controls the track device (step 210); the control host is interconnected with the remote host through the network module, wherein the remote host stores the fixture number and its corresponding fixture life, and stores the consumable number and its corresponding consumable life (step 220); the control host scans the fixture and consumables through the scanner to obtain the corresponding fixture number and consumable number, and the processing unit The control host continuously calculates the use status of the fixture and consumables (step 230); the control host inquires the remote host about the corresponding fixture life and consumable life according to the read fixture number and consumable number, and the processing unit calculates the corresponding remaining fixture life and consumable life according to the use status, fixture life and consumable life, and outputs the remaining fixture life and consumable life through the display element (step 240); and when the remaining fixture life or the remaining consumable life is lower than the threshold value, the control host generates a stop signal to transmit to the programmable logic controller, so that the programmable logic controller controls the track device to stop moving (step 250). In this way, the control host 120 can scan the jig and consumables to obtain the corresponding jig life and consumable life, and continuously calculate the use status of the jig and consumables, and then calculate the remaining jig life and consumable life according to the use status, jig life and consumable life. When one of the two is lower than the threshold value, a stop signal is generated to be transmitted to the programmable logic controller 101 of the track device 100, so that the programmable logic controller 101 controls the track device 100 to stop moving, so as to avoid using poor quality jigs or consumables for printing.

[0046] The following match Figure 3 and Figure 4 The following description is given by way of example. Please refer to Figure 3 , Figure 3 Schematic diagram of applying the present invention to the consumables control of the printer fixture. In actual implementation, the front end of the printer 310 is provided with a track device 100. Then, the control host 320 can be as follows Figure 3 As shown, the scanner 321 is connected by an external method (such as using a connecting line) to scan the fixture 301 and the consumables 302. In addition, the control host 320 can be connected to the production maintenance system 330 wirelessly, and electrically connected to the programmable logic controller of the track device 100. When performing consumable control of the fixture of the printer 310, the fixture 301 and the consumables 302 can be scanned by the scanner 321 to obtain the corresponding fixture number and consumable number, and the use status of the fixture 301 and the consumables 302 can be continuously calculated, such as: the use time, the number of times it is used, etc. For example, using the fixture 301 once can accumulate the number of times it is used once, or using the fixture 301 for one minute can accumulate the use time for one minute. Next, the control host 300 queries the remote host (i.e., the production maintenance system 330) for the corresponding fixture life and consumable life according to the read fixture number and consumable number, and calculates the corresponding fixture remaining life and consumable remaining life according to the use status, fixture life and consumable life, and outputs the fixture remaining life and consumable remaining life through the display element. For example, assuming that the fixture life is "36500 hours" and the use status of fixture 301 is "500 hours", the "fixture remaining life" of fixture 301 is the "fixture life" minus its "use status", that is, the fixture remaining life is "36000 hours", and the remaining life of the consumable is calculated and deduced in the same way. Next, when the remaining life of the fixture or the remaining life of the consumables is lower than a threshold value (e.g., 50 hours), the control host 320 can generate a stop signal to transmit to the programmable logic controller, so that the programmable logic controller controls the track device 100 to stop moving, allowing the operator to replace the fixture 301 or consumables 302, thereby avoiding the use of poor quality fixtures 301 or consumables 302 during the production process, which would reduce production quality and increase consumables consumption.

[0047] like Figure 4 Indicated, Figure 4 Schematic diagram of the present invention for monitoring the remaining life of the fixture and consumables. As mentioned above, the display element 124 displays the remaining life of the fixture and the remaining life of the consumables. In actual implementation, it can be as follows Figure 4As shown, a monitoring window 400 is displayed on the display element 124, which may include: a fixture consumable display block 410, a remaining life display block 420 and a graphical display block 430, which are used to display the fixture consumable name, remaining life and a graphical presentation of the remaining life. It can be clearly seen from the figure that when the consumable is "solder paste", its remaining consumable life is "1335 minutes", and the proportion of "consumable remaining life" to "consumable life" can be seen in the graphical display block 430, where the dot part represents the proportion of the remaining consumable life. Similarly, when the fixture is a "steel plate", its fixture remaining life is "325 minutes", and the proportion of "fixture remaining life" to "fixture life" can be seen in the graphical display block 430, where the dot part represents the proportion of "fixture remaining life".

[0048] To sum up, it can be seen that the difference between the present invention and the prior art lies in that the control host scans the jig and consumables to obtain the corresponding jig life and consumable life, and continuously calculates the use status of the jig and consumables, and then calculates the remaining jig life and consumable life according to the use status, jig life and consumable life, and when one of the two is lower than the threshold value, a stop signal is generated to be transmitted to the programmable logic controller of the track device, so that the programmable logic controller controls the track device to stop moving, thereby avoiding the use of poor quality jigs or consumables for printing. This technical means can solve the problems existing in the prior art, thereby achieving the technical effect of improving printing quality and reducing consumable loss.

[0049] Although the present invention is disclosed as above with the aforementioned embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the claims attached to this specification.
