[0048] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0049] In the process of mixing raw materials of photovoltaic glass, the mixing equipment mixes and stirs the raw materials after receiving them from the upstream equipment, and discharges the mixture after the mixing and stirring is completed, and continues to receive the next input from the upstream equipment to mix the raw materials for the next time. Among them, the upstream equipment puts the raw materials into the electronic scale, and the electronic scale is designed using the incremental method. When the electronic scale bucket reaches the preset weight value as required, the electronic scale hopper discharges the materials. When the instrument corresponding to the electronic scale bucket shows a net weight of 0, it is considered that the electronic scale has completed the discharge. The electronic scale discharges the materials first onto the belt, and then is sent to the mixing equipment through the belt. This method prevents the mixing equipment from adding less raw materials.

[0050] However, the following two situations are prone to occur when the mixing equipment is discharging materials: First, after the mixing equipment is completed, the raw materials in the mixing equipment are not discharged in time, resulting in residues inside. At this time, the discharge door has been closed, and the feed door begins to receive the second feeding from the upstream equipment, resulting in too much raw materials in the mixing equipment. Second, after the mixing equipment is completed, the discharge door in the mixing equipment receives an opening signal, but due to a mechanical failure, the discharge door cannot be opened normally, and the raw materials in the mixing equipment are not discharged. At this time, the feed door begins to receive the second feeding from the upstream equipment, resulting in too much raw materials in the mixing equipment.

[0051] On the one hand, if there are too many raw materials in the mixing equipment, it is easy to cause uneven mixing, which can easily affect the production quality of photovoltaic glass. On the other hand, if the weight of the raw materials is different each time, it is easy to cause the uniformity of the raw materials mixing each time, which will also affect the production quality of photovoltaic glass.

[0052] In order to accurately control the weight of raw materials in the stirring equipment and solve the problem of uneven mixing of raw materials, in the implementation mode of the present application, after each upstream device completes discharging of materials to the stirring equipment, the real-time working current of the stirring motor in the stirring equipment is detected to determine whether the weight of raw materials in the stirring equipment exceeds the preset standard weight range. If it exceeds the standard weight range, the discharge door of the stirring equipment is controlled to open to discharge excess raw materials, so that the weight of raw materials in the stirring equipment is within the standard weight range, so as to accurately control the weight of raw materials in the stirring equipment and solve the problem of uneven mixing of raw materials.

[0053] In order to make the purpose, technical solutions and advantages of the present invention more clear, specific embodiments will be described below in conjunction with the accompanying drawings.

[0054] Figure 1 The implementation flow chart of the stirring control method provided by the embodiment of the present invention is described in detail as follows:

[0055] Step 101, after the upstream device has completed discharging materials to the stirring device, monitor the real-time working current of the stirring motor in the stirring device.

[0056] In an embodiment of the present invention, the discharge time can be accumulated when the upstream device starts to discharge the material to the stirring device. When the set time is reached, it is determined that the upstream device has completed discharging the material to the stirring device. Alternatively, the upstream device can send a discharge completion signal after determining that the discharge is completed. When the discharge completion signal is received, it is determined that the upstream device has completed discharging the material.

[0057] Step 102: Determine whether the weight of the raw materials in the stirring device exceeds a preset standard weight range based on the real-time working current.

[0058] Most stirring devices use a stirring motor to perform stirring operations. The stirring motor here can be an asynchronous motor. It should be noted that there is a corresponding relationship between the weight of the raw materials in the stirring device and the real-time working current of the stirring motor. The more raw materials loaded in the stirring device, the greater the working current of the stirring motor.

[0059] In some embodiments, the real-time operating current may include: a plurality of real-time operating current values ​​within a preset time period.

[0060] When determining whether the weight of raw materials in the mixing equipment exceeds the preset standard weight range, the standard working current range of the mixing motor corresponding to the weight of the raw materials loaded in the mixing equipment is within the standard weight range can be obtained first; if multiple real-time working current values ​​within the preset time are all greater than the upper limit value of the standard working current range, it is determined that the weight of the raw materials in the mixing equipment exceeds the standard weight range.

[0061] Based on the corresponding relationship between the weight of the raw materials loaded in the stirring device and the real-time working current of the stirring motor, the embodiment of the present invention pre-acquires the standard working current interval of the stirring motor when the weight of the raw materials is in the standard weight interval. Subsequently, by comparing the magnitude relationship between the real-time working current and the upper limit value of the standard working current interval, it is determined whether the weight of the raw materials in the stirring device exceeds the standard weight interval.

[0062] Here, the raw material weight exceeding the preset standard weight interval means that the raw material weight is greater than the upper limit value of the preset standard weight interval.

[0063] To avoid misjudgment, the embodiment of the present invention can monitor multiple real-time working current values ​​within a preset time period. Only when the multiple real-time working current values ​​are all greater than the upper limit value of the standard working current range, it is determined that the weight of the raw materials in the stirring equipment exceeds the standard weight range.

[0064] Exemplarily, the preset time period can be determined according to actual conditions. Exemplarily, the preset time period can be 1 minute. That is, within 1 minute after the upstream device completes discharging the material to the stirring device, the working current of the stirring motor is monitored in real time to obtain multiple real-time working currents, and based on the magnitude relationship between the multiple real-time working currents and the upper limit value of the above-mentioned standard working current range, it is determined whether the weight of the raw materials in the stirring device exceeds the standard weight range.

[0065] Step 103, if the weight of the raw materials exceeds the standard weight range, the discharge door of the stirring device is controlled to open for discharging, until the weight of the raw materials in the stirring device is determined to be in the standard weight range based on the real-time working current, and then the discharge door of the stirring device is controlled to close to put the stirring device in a standard stirring state.

[0066] The embodiment of the present invention can monitor the real-time working current of the stirring motor in real time after controlling the discharge door of the stirring device to open and discharge the material, until the real-time working current of the stirring motor is within the standard working current range, and determine that the weight of the raw materials in the stirring device is within the standard weight range, and control the discharge door of the stirring device to close.

[0067] It should be noted that, during the entire raw material mixing process, the stirring motor in the stirring device is always running to perform the stirring operation. The standard stirring state here refers to the operating state of the stirring device when the weight of the raw materials in the stirring device is within the standard weight range.

[0068] Compared with the prior art, the embodiment of the present invention determines whether the weight of the raw materials in the stirring device exceeds the standard weight range based on the real-time working current of the stirring motor in the stirring device after the upstream equipment completes discharging, and controls the discharge door of the stirring device to open when it exceeds the standard weight range, and controls the discharge door of the stirring device to close when the weight of the raw materials in the stirring device is within the standard weight range, so as to ensure that the weight of the raw materials in the stirring device is within the standard weight range, thereby making the mixing uniformity of the raw materials in the stirring device consistent, so as to avoid affecting the production quality of photovoltaic glass due to uneven mixing and stirring.

[0069] The stirring control method in the above embodiment is only for the scenario after the upstream equipment has completed discharging the material into the stirring device. It can be understood that the raw material mixing process of photovoltaic glass includes not only the scenario after the upstream equipment has completed discharging the material into the stirring device, but also the scenario after the upstream equipment has discharged the material into the stirring device and the stirring device has evenly stirred the material before discharging the material. Another embodiment of the present invention also provides a new stirring control method to be applicable to the entire photovoltaic glass raw material mixing process.

[0070] See also Figure 2 , the stirring control method comprises:

[0071] Step 201, in response to the discharge signal of the upstream device, monitor the real-time working current of the stirring motor in the stirring device.

[0072] When the upstream device has finished preparing the materials, the upstream device can send a discharge signal to notify the mixing device to prepare to receive a new batch of raw materials. After receiving the discharge signal from the upstream device, the embodiment of the present invention can first detect the real-time working current of the mixing motor in the mixing device to determine the weight of the raw materials in the mixing device, and then decide whether to accept the discharge of the upstream device.

[0073] Step 202, when the real-time working current is within the no-load current interval corresponding to the no-load state of the stirring device, the feeding door in the stirring device is controlled to open to perform the feeding operation.

[0074] The embodiment of the present invention determines the no-load current interval in advance according to the real-time working current of the stirring motor when the stirring device is no-load. If the real-time working current is in the no-load current interval, it can be determined that the stirring device is in a no-load state, that is, the stirring device is not loaded with raw materials and is in a no-load stirring state.

[0075] After determining that the stirring device is in a no-load stirring state and receiving a discharge signal from an upstream device, the embodiment of the present invention controls a feed door in the stirring device to open to receive the discharge of the upstream device.

[0076] In some embodiments, an image recognition system may be provided in the stirring device to perform image recognition on the inside of the stirring device to further determine the condition of the raw materials inside the stirring device to avoid misjudgment.

[0077] On the basis of being equipped with an image recognition system, when the real-time working current is in the no-load current range corresponding to the no-load state of the stirring equipment, the current image in the stirring equipment can be obtained first; then, based on the current image, it is determined whether the stirring equipment is in a no-load state; when the stirring equipment is in a no-load state, the feeding door in the stirring equipment is controlled to open.

[0078] That is, when the real-time working current is in the no-load current interval, it is further determined whether there is residual raw material in the mixing device that has not been discharged according to the image in the mixing device. When the real-time working current is in the no-load current interval and the current image in the mixing device shows that there is no residual raw material in the mixing device, in response to the discharge signal of the upstream device, the feed door is controlled to open to receive the raw material discharged by the upstream device.

[0079] Step 203, after the upstream device has completed discharging the material to the stirring device, monitoring the real-time working current of the stirring motor in the stirring device;

[0080] Step 204, based on the real-time working current, determining whether the weight of the raw material in the stirring device exceeds a preset standard weight range;

[0081] Step 205, if the weight of the raw materials exceeds the standard weight range, the discharge door of the stirring device is controlled to open for discharging, until the weight of the raw materials in the stirring device is determined to be in the standard weight range based on the real-time working current, and then the discharge door of the stirring device is controlled to close to put the stirring device in a standard stirring state.

[0082] The specific implementation of steps 203-205 here can be found in Figure 1 The corresponding embodiments will not be described in detail here.

[0083] In some embodiments, after step 205, the method further includes:

[0084] Step 206, after the raw materials in the current stirring device are stirred evenly, the discharge door in the stirring device is controlled to open, and the discharge time is started to be calculated.

[0085] In the embodiment of the present invention, after the stirring device begins to be in the standard stirring state, the stirring time can be accumulated, and when the stirring time reaches the set stirring time, it is determined that the raw materials in the current stirring device are stirred and mixed uniformly, that is, the stirring and mixing of the current batch of raw materials is completed. At this time, the discharge door is controlled to open and the uniformly mixed raw materials are discharged.

[0086] Step 207, when the discharge time reaches the preset discharge completion time, the real-time working current of the stirring motor in the stirring device is monitored.

[0087] Ideally, after the discharge time reaches the preset discharge completion time, the discharge is completed and the stirring device returns to the no-load stirring state. However, considering that there may be problems such as slow discharge speed or discharge door failure, resulting in the actual discharge not being completed, the embodiment of the present invention first monitors the real-time working current of the stirring motor after the discharge time reaches the preset discharge completion time to determine whether there is any raw material left in the stirring device that has not been discharged.

[0088] Step 208: If the real-time working current exceeds the no-load current interval corresponding to the no-load state of the stirring device, a real-time image inside the stirring device is acquired.

[0089] Here, if the real-time working current exceeds the above-mentioned no-load current range, it can be determined that there are still raw materials remaining in the mixing device that have not been discharged. At this time, an alarm message can be sent to remind the staff that a fault may occur. Subsequently, a real-time image of the mixing device is obtained through the image recognition system to further determine the raw material situation inside the mixing device.

[0090] In some embodiments, if the real-time working current is in the above-mentioned no-load current range, it is determined that the discharging of the stirring equipment is completed, and the discharging door is controlled to be closed.

[0091] Step 209, if the real-time image shows that the stirring device is not in a no-load state, the discharge door in the stirring device is controlled to remain open until the real-time working current is in a no-load current range, and then the discharge door in the stirring device is controlled to close.

[0092] If the real-time image also shows that the mixing equipment is not in a no-load state, the discharge door is controlled to remain open until the real-time working current of the mixing motor is in the no-load current range, confirming that the discharging is completed, and the discharge door is controlled to close to complete the mixing of a batch of raw materials.

[0093] The temperature of the raw materials after mixing will also affect the production quality of photovoltaic glass. However, in the related art, most of the discharged raw materials are manually detected after the mixing equipment discharges the mixed raw materials. If the temperature of the raw materials after mixing does not reach the preset temperature value, it will also affect the production quality of photovoltaic glass.

[0094] In order to ensure that the temperature of the raw materials after uniform mixing can reach a preset temperature value, in some embodiments, a temperature adjustment device can be provided in the stirring device.

[0095] On the basis of setting up the temperature adjustment device, after the raw materials in the current stirring equipment are stirred evenly, the temperature adjustment device can be used to monitor the temperature of the raw materials in the stirring equipment; if the temperature of the raw materials is lower than the preset temperature value, the temperature adjustment device is controlled to heat up the raw materials, and the stirring equipment is controlled to continue stirring, until the temperature of the raw materials is greater than or equal to the preset temperature value, and then the discharge door in the stirring equipment is controlled to open.

[0096] In order to ensure the temperature of the raw materials after uniform mixing, the embodiment of the present invention detects the temperature of the raw materials after the raw materials are uniformly mixed. If the temperature of the raw materials is less than the preset temperature value, the temperature adjustment device is controlled to heat the raw materials and continue to stir until the temperature of the raw materials is greater than or equal to the preset temperature value, and then the discharge door in the stirring device is controlled to open, and the raw materials that are uniformly mixed and whose temperature reaches the preset temperature value are discharged, completing the mixing of a batch of raw materials.

[0097] Combine the following Figure 3 , the stirring control method provided in an embodiment of the present invention is specifically introduced.

[0098] When the mixing equipment starts to run, there is no raw material in the mixing equipment and it is in a no-load mixing state;

[0099] After the upstream equipment has finished preparing the materials, it is ready to discharge the materials. When the mixing equipment is in the no-load mixing state, the feeding door is opened to receive the raw materials and the timing starts;

[0100] After reaching the set time, confirm that the upstream equipment has completed discharging and close the feeding door;

[0101] Monitor the real-time working current of the stirring motor in the stirring equipment and compare it with the standard working current range. If the real-time working current exceeds the standard working current range, open the discharge gate until the real-time working current is in the standard working current range and then close the discharge gate.

[0102] The raw materials in the standard weight range are continuously stirred in the stirring device. After being stirred and mixed evenly, the temperature of the raw materials in the stirring device is monitored.

[0103] If the temperature is lower than the preset temperature value, the raw materials in the stirring device are heated up and stirred continuously until the temperature is greater than or equal to the preset temperature value, and the discharge door is controlled to open to discharge the raw materials in the stirring device;

[0104] After the discharge door is opened, the real-time working current of the stirring motor and the image collected by the image recognition system are used to comprehensively judge whether there are any remaining raw materials in the stirring equipment;

[0105] Only when the real-time working current is in the no-load current range and the real-time image shows that the mixing equipment is in a no-load state, the discharge door is controlled to close and the raw material mixing is completed.

[0106] See also Figure 4 The embodiment of the present invention also provides a stirring system. The stirring system includes: an upstream device, a control device and a stirring device. The upstream device is used to prepare raw materials and discharge them to the stirring device; the stirring device is used to perform the raw material stirring operation; the control device is used to perform the above stirring control method.

[0107] Among them, the mixing equipment is equipped with an image recognition system, a temperature adjustment device, an industrial computer, a mixing motor driver and a mixing motor.

[0108] The image recognition system here may be an infrared image recognition system, which is used to obtain the internal image of the stirring device and transmit it to the control device, so that the control device can determine the stirring condition of the raw materials inside the stirring device based on the internal image of the stirring device.

[0109] The temperature adjustment device includes a temperature detection device and a temperature adjustment device, which are used to detect the temperature of the raw materials inside the stirring device and adjust the temperature of the raw materials inside the stirring device. The stirring motor driver is used to drive the stirring motor so that the stirring motor performs the stirring operation. The stirring motor driver can also feed back the real-time working current of the stirring motor to the control device and the industrial computer.

[0110] The industrial computer is used to receive the real-time working current and display the current trend curve.

[0111] It should be understood that the order of execution of the steps in the above embodiment does not necessarily mean the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present invention.
