Description

Technical Field

[0001] The present invention relates to the technical field of glass cleaning, and in particular to an information-based glass tracking control method and system for a cleaning machine, and a cleaning machine. Background Art

[0002] The cleaning machine is a kind of equipment used in the existing solar glass production line to clean the glass. After the glass leaves a process section that produces a lot of dust, or before entering a closed dust-free process section, the cleaning machine is needed to clean the glass on the production line.

[0003] There are many types of cleaning machines, but in the information production line, they are basically offline stand-alone devices. Although they are embedded in the production line, there is no information interaction with the line itself, and there is a lack of information tracking and information feedback of the equipment itself, which often makes the cleaning machine not an intelligent and fully automated production. In addition, through simple photoelectric control, the roller equipment has a single control over glass transportation and cannot complete some complex interlocking controls.

[0004] In the prior art, the invention patent with the patent publication number CN113670053A discloses a dynamic tracking wind knife system and drying method for a high-speed glass cleaning machine. The dynamic wind knife in the article tracks the tail of the glass substrate with high-pressure wind blown out from the wind knife nozzle, so that the wind knife can continuously dry the tail of the glass which is the most difficult to dry. In this patent, before the improvement, the wind knife was fixed, and the glass flowed to the wind knife, and the wind knife dried the glass, but it was difficult to dry the tail of the glass. This patent improves the wind knife so that the wind knife can move dynamically and track the tail of the glass. This patent does not need to track and locate the flow position of the glass, as long as the wind knife is kept moving relative to the glass to achieve dynamic drying of the tail of the glass by the wind knife. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an information-based glass tracking control method for a cleaning machine.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] An information-based glass tracking control method for a cleaning machine includes:

[0008] The glass tail is used as the reference to represent the position of the glass, and the initial photoelectric position is used as the starting point;

[0009] When the glass passes the initial photoelectric position, it confirms with the upstream signal and obtains the glass information sent by the upstream device;

[0010] Read the real-time speed of the glass roller and combine it with time to obtain the distance the glass has traveled;

[0011] According to the length of a roller section, the position of the glass tail can be obtained in real time through the distance of glass flow;

[0012] Dynamically adjust the glass washing production line according to the real-time position of the glass tail and glass information.

[0013] The initial information of the glass is obtained from upstream, and the speed of the roller where the glass is located is obtained in real time, so as to calculate the position of the glass. The information of each piece of glass is stored separately in a separate storage unit of the PLC, and the real-time updated position is written into each glass information block, thereby realizing the information tracking of the glass.

[0014] With information tracking as the basis, the control system can monitor the position of each piece of glass in the cleaning machine. Guided by the position, it monitors the glass and immediately reads the specific information of the glass when it enters a certain small link, so as to adjust the specific production parameters according to the different properties of the glass, or control the start and stop of the roller.

[0015] In one embodiment of the present invention, based on the glass tail as the reference tracking, the glass head position tracking is obtained in combination with the glass length.

[0016] In one embodiment of the present invention, the glass washing production line is dynamically adjusted, including: setting a washing stop process according to the real-time position of the glass tail:

[0017] Set the distance threshold of the receiving area. When the distance of the glass tail is greater than the distance threshold of the receiving area, a workstation is vacated in the receiving area, and the glass tail has passed the dust removal area. At this time, the first roller conveyor corresponding to the receiving area is controlled to stop, and the receiving robot places another piece of glass. After placing it, wait for the cleaning chamber to be vacated. When the next piece of glass arrives at this position, the control is repeated.

[0018] Set the cleaning chamber distance threshold. When the distance of the glass tail is greater than the cleaning chamber distance threshold, the glass head is about to leave the cleaning chamber. Check whether there are pieces waiting in the downstream transmission area. If there are, control the second roller section corresponding to the cleaning chamber to stop. If not, the second roller section keeps rotating. When the next piece of glass reaches this position, repeat the control.

[0019] Set the distance threshold of the first transmission zone. When the distance of the glass tail is greater than the distance threshold of the first transmission zone, the glass completely enters the transmission zone, a station is vacated in the cleaning chamber, and the first roller is controlled to put the glass into the cleaning chamber. At this time, the glass is ready to be transported out of the transmission zone; when the next piece of glass reaches this position, the control is repeated;

[0020] Set the distance threshold of the second transmission zone. When the distance of the glass tail is greater than the distance threshold of the second transmission zone, the glass enters the transmission zone, adjusts the setting speed of the third roller corresponding to the transmission zone to synchronize with the downstream roller, and sends the glass information to the downstream equipment; when the next piece of glass reaches this position, repeat the control;

[0021] Set the distance threshold of the third transmission zone. When the distance of the glass tail is greater than the distance threshold of the third transmission zone, the glass completely leaves the transmission zone, vacating the work station, and controlling the second roller to deliver the glass; when the next piece of glass reaches this position, repeat the control.

[0022] In one embodiment of the present invention, the glass cleaning production line is dynamically adjusted, including: setting a frame height adjustment distance threshold; when the distance tracked by the glass head reaches a position corresponding to the frame height adjustment distance threshold, the height of the frame on the cleaning chamber is automatically adjusted according to the thickness of the glass.

[0023] In one embodiment of the present invention, the glass cleaning production line is dynamically adjusted, including: setting a cleaning temperature distance threshold, and when tracking the distance of the glass head to a position corresponding to the cleaning temperature distance threshold, automatically adjusting the heating degree of the cleaning water according to the type of glass.

[0024] In one embodiment of the present invention, the glass cleaning production line is dynamically adjusted, including: setting a cleaning level distance threshold; when the distance of the glass head is tracked to reach the position corresponding to the cleaning level distance threshold, the speed of the cleaning brush is automatically adjusted according to the cleaning level of the glass.

[0025] In one embodiment of the present invention, when the glass tail leaves the initial photoelectric position and the photoelectric signal has a falling edge signal, the position value is reset to 0.

[0026] The present invention also provides a system for executing the above-mentioned information-based glass tracking control method for a cleaning machine, comprising:

[0027] Tracking start module, used to represent the position of the glass with the tail of the glass as the reference and the initial photoelectric position as the starting point;

[0028] Glass information module, used to confirm with upstream signals when the glass passes through the initial photoelectric position, and obtain glass information sent by upstream equipment;

[0029] The real-time distance module is used to read the real-time speed of the glass flow roller and obtain the distance of the glass flow in combination with the time;

[0030] The real-time position module is used to obtain the position of the glass tail in real time according to the length of a roller and the distance the glass flows;

[0031] The production line dynamic adjustment module is used to dynamically adjust the glass washing production line according to the real-time position of the glass tail and glass information.

[0032] The present invention also provides a cleaning machine, in which the glass position and glass information obtained by real-time tracking using the above-mentioned cleaning machine information-based glass tracking control method are stored.

[0033] Compared with the prior art, the invention has the following beneficial effects: the automation performance of the equipment is increased, the manual operation cost is reduced, because the production parameters can be modified automatically and intelligently. The real-time tracking of the glass information position allows the photoelectric to play an auxiliary role and can be shielded when necessary, thereby improving the stability of the equipment. The safety of the equipment is improved, because the information of the equipment can be fed back to multiple supervisory levels in real time. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to facilitate those skilled in the art to understand the technical solution of the present invention, the technical solution of the present invention is further described in conjunction with the accompanying drawings of the specification.

[0038] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0039] See also Figure 1 As shown, the present invention provides an information-based glass tracking control method for a cleaning machine, comprising:

[0040] S10, taking the tail of the glass as a reference to represent the position of the glass, and taking the initial photoelectric position as the starting point.

[0041] In one embodiment of the present invention, the initial photoelectric position is set at the initial position of the glass washing production line. At least one photoelectric sensor is set at the initial position of the glass washing production line. Alternatively, a photoelectric sensor is set at a certain distance on the glass washing production line. When the glass flows to the corresponding position of the photoelectric sensor, according to the photoelectric signal, it can be roughly determined that the glass is currently in the approximate position area of ​​the glass washing production line. In addition, with the initial photoelectric position as the starting point and 1mm as the unit, a one-dimensional coordinate system for tracking the position can be generated.

[0042] S20, when the glass passes through the initial photoelectric position, it confirms with the upstream signal and obtains the glass information sent by the upstream device.

[0043] In one embodiment of the present invention, the glass information receiving area is generated, and the photoelectric sensor at the initial photoelectric position and the upstream signal are confirmed. The photoelectric sensor detects the glass and receives the signal that the upstream controller has released the glass. The PLC system reads the glass information sent by the upstream to generate a glass tracking information data block. The information block data content includes: glass length, width, thickness, model, cleaning level, ID identification number, etc., and the information transmission content can be further expanded according to future production needs.

[0044] S30, reading the real-time speed of the glass flow roller, and combining it with the time to obtain the distance of the glass flow.

[0045] In one embodiment of the present invention, the glass tail is used as a reference in the coordinate system planning. When the glass tail is on a roller section, the real-time speed of the current roller is read. For example, when the glass tail is on roller No. 1, the controller reads the speed of roller No. 1. The position algorithm adopts the idea of ​​calculus. The PLC controller scans and uses interrupt processing. It interrupts once every 10ms to read the roller speed, calculates the travel distance of the glass in the last 10ms, and then accumulates the distance to calculate the tracking position. In this way, the real-time position of the glass tail is calculated.

[0046] S40, obtaining the position of the glass tail in real time according to the length of one roller section and the distance of glass flow.

[0047] In one embodiment of the present invention, assuming that the length of a roller section is 2 meters, combined with the roller speed at the initial position and the flow time, the position of the glass tail is 2001 mm relative to the origin, that is, it enters the second roller section at this time, then the speed of the second roller is read, combined with the time, to obtain the flow distance, and so on, and the corresponding position of the glass tail is the sum of the lengths of each roller section passed.

[0048] S50, dynamically adjusting the glass washing production line according to the real-time position of the glass tail and the glass information.

[0049] In one embodiment of the present invention, based on the glass tail as the reference tracking, the glass head position tracking is obtained in combination with the glass length.

[0050] In this embodiment, the coordinate system planning takes photoelectric No. 1 as the starting point, and the photoelectric corresponding to the initial photoelectric position, when the glass tail leaves photoelectric No. 1, that is, when the detection glass position is in the area near the initial photoelectric position, and the photoelectric signal has a falling edge signal, the position value is reset to 0. The same is true for other photoelectrics. When the detection glass position is in the area near photoelectric No. 2, and photoelectric No. 2 has a falling edge signal, the distance of photoelectric No. 2 from photoelectric No. 1 is written into the position.

[0051] In one embodiment of the present invention, the method of obtaining the position of the glass of the present invention is used to make the photoelectric inside the cleaning machine play an auxiliary role, and the photoelectric can be selectively used for position correction. For example, if the photoelectric near the cleaning bin is more likely to be disturbed by water and there is a concern about interference, or if there is a problem with the photoelectric at any position, the correction function can be turned off.

[0052] See also Figure 1 and Figure 2 As shown, in one embodiment of the present invention, when the glass on the production roller of the cleaning machine reaches a fixed position, there will be an automatic parking process. The traditional cleaning machine can only rely on photoelectric control. Once the photoelectric is damaged, it will affect the production. The cleaning machine under tracking control can calculate the actual position of the glass, and can perform parking control according to the position value. Photoelectric can assist in correcting the position, so that the cleaning machine control system has double stability protection, as follows: dynamically adjust the glass cleaning production line, and set the cleaning parking process according to the real-time position of the glass tail:

[0053] In this embodiment, a distance threshold of the receiving area is set, specifically 2200mm. When the distance of the position of the glass tail is greater than the distance threshold of the receiving area, a workstation is vacated in the receiving area, and the glass tail has passed the dust removal area. At this time, the first roller conveyor corresponding to the receiving area is controlled to stop, and the receiving manipulator places another piece of glass. After placing it, it waits for the cleaning chamber to be vacated. When the next piece of glass reaches this position, the control is repeated.

[0054] In this embodiment, a cleaning chamber distance threshold is set, specifically 3800 mm. When the distance of the glass tail is greater than the cleaning chamber distance threshold, the glass head is about to leave the cleaning chamber, and it is detected whether there are pieces waiting in the downstream transmission area. If there are, the second roller section corresponding to the cleaning chamber is controlled to stop, if not, the second roller section keeps rotating. When the next piece of glass reaches this position, the control is repeated.

[0055] In this embodiment, a distance threshold of the first transmission zone is set, specifically 5400 mm. When the distance of the position of the glass tail is greater than the distance threshold of the first transmission zone, the glass completely enters the transmission zone, a station is vacated in the cleaning chamber, and the first roller is controlled to put the glass into the cleaning chamber. At this time, the glass is ready to be transferred out of the transmission zone. When the next piece of glass reaches this position, the control is repeated.

[0056] In this embodiment, a distance threshold of the second transmission zone is set, specifically 5600 mm. When the distance of the glass tail is greater than the distance threshold of the second transmission zone, the glass enters the transmission zone, the speed of the third roller corresponding to the transmission zone is adjusted to be synchronized with the downstream roller, and the glass information is sent to the downstream device. When the next piece of glass reaches this position, the control is repeated.

[0057] In this embodiment, a distance threshold of the third transmission zone is set, specifically 6200 mm. When the distance of the glass tail is greater than the distance threshold of the third transmission zone, the glass completely leaves the transmission zone, vacating the work station, and controlling the second roller conveyor to deliver the glass; when the next piece of glass reaches this position, the control is repeated.

[0058] In one embodiment of the present invention, the glass washing production line is dynamically adjusted, including: setting a frame height adjustment distance threshold, and automatically adjusting the height of the frame on the washing chamber according to the thickness of the glass when the distance of the glass head position is tracked to the position corresponding to the frame height adjustment distance threshold. The frame height adjustment distance threshold generally tracks the distance of 300mm between the glass head position and the washing chamber, and adjusts the height of the frame on the washing chamber. If it is detected that the thickness is inconsistent with the last operation, the washing chamber is vacated and then automatically adjusted.

[0059] In one embodiment of the present invention, the glass washing production line is dynamically adjusted, including: setting a washing temperature distance threshold, and automatically adjusting the degree of heating of the washing water according to the type of glass when the distance of the glass head is tracked to the position corresponding to the washing temperature distance threshold. In this embodiment, the water temperature is generally adjusted when the glass head is tracked to be 300mm away from the washing bin. If it is detected that the temperature is inconsistent with the last working temperature, the washing bin is vacated, and then the temperature is automatically adjusted. When the temperature is basically consistent, the glass is again introduced for washing.

[0060] In one embodiment of the present invention, the glass cleaning production line is dynamically adjusted, including: setting a cleaning level distance threshold; when the distance of the glass head is tracked to the position corresponding to the cleaning level distance threshold, the speed of the cleaning brush is automatically adjusted according to the cleaning level of the glass. In this embodiment, the brush speed is generally adjusted when the glass head enters the cleaning chamber 100mm, and the brush speed is controlled by a frequency converter and can be adjusted quickly without waiting.
