The upper computer may be a computer device or a server, etc. with processing, analyzing and controlling functions.

A process refers to a particular step in the manufacture, production, or achievement of a particular result, and is the fundamental unit of composition in the production process. For example, in the case of manufacturing the spring piece, the spring piece may be manufactured by blanking, stamping, heat treatment, or the like. All the working procedures in the production process can be divided into production working procedure sections, and at least one working procedure is included in 1 production working procedure section. Fig. 1 shows an example of two production steps, including a production step 1 and a production step 2, each production step including 3 steps, and in practice, the number of production steps and the number of steps in each production step are not limited.

Each production process section further includes a reflow location, and it should be noted that the reflow location of each production process section is located before the first process in each production process section is fed.

The target material may be a material that is re-brought on line after a problem occurs in the production process from the production line, i.e. a reflow material. When the target material needs to be refluxed, the target reflux position of the target material can be determined from a plurality of reflux positions according to the material state of the target material, and then the target material is controlled to be fed from the target reflux position so as to flow into a target process, wherein the target process can be any process in a production process section to which the target reflux position belongs. For example, as shown in fig. 2, in the production process section to which the target reflow position 201 belongs, the upper computer may control the target material to be fed from the target reflow position 201 and flow into the target process 202, at this time, the upper computer may acquire the material information of the target material entering the target process 202 and the standard program function block corresponding to the pre-configured target process, and then configure the material information of the target material in the standard program function block to execute the standard program function block, so as to realize the reflow control of the target material. The material state of the target material may indicate a process and/or operation of the target material that needs to be reworked, and the material information of the target material may include a number of the target material, a material state, and the like.

Wherein a standard program function block is a kind of program block for performing a specific function or algorithm. Standard program function blocks may be programmed by a programmable logic controller (Programmable Logic Controller, PLC).

Taking a target material as a battery module as an example, as shown in fig. 3, the processes in the production process of the battery module include a heating and standing process 301, a pre-welding photographing process 302, a low-voltage insulation process 303, a ceramic coating separator (Ceramic Coating Separator, CCS) assembling process 304, a laser (BSB) welding process 305, an automatic dust removing process 306, a post-welding detection process 307, an End-of-life (EOL) \thickener carboxymethyl cellulose (Carboxymethyl Cellulose, CMC) process 308, an upper cover mounting process 309, an automatic labeling process 310, a full-size process 311, a turnover inspection process 312, and a module unloading process 313.

Then, the production process of the battery module includes 3 reflow positions, wherein a first reflow position 314 exists between the heating and standing process and the photographing process before soldering, a second reflow position 315 exists between the automatic dust removing process and the detecting process after soldering, and a third reflow position 316 exists between the upper cover mounting process and the automatic labeling process.

For example, if the material state of the target material is CCS reflow, it may indicate that the target material needs to be reworked in CCS assembling process 304, the target reflow position of the target material may be first reflow position 314, and in this case, the target process may be any process between the photographing process 302 before soldering, low-voltage insulating process 303, and CCS assembling process 304, that is, the target process may be any process between the processes corresponding to the target reflow position and the material state. If the material state of the target material is full-size detection reflow, it may indicate that the target material needs to be detected in full-size process 311, and the target reflow position of the target material may be the third reflow position 316.

It should be noted that, the production process segments of the production process division of the battery module in fig. 3 are only examples, and may be set according to the requirements. For example, the process from the pre-weld photo process 302 to the post-weld inspection process 307 is referred to as a production process stage, and the process from the EOL/CMC process 308 to the module off-line process 313 is referred to as a production process stage.

In one exemplary embodiment, as shown in fig. 8, a material reflow method is provided, the method comprising the steps of:

s801, controlling the target material to flow into the target process from the target reflow position in response to the reflow request of the target material.

The production line of the target material comprises a plurality of backflow positions, and the target backflow positions are determined according to the material state of the target material.

Taking the production of the battery module as an example, please continue to refer to fig. 3, in the case that a certain material has a problem in the BSB welding process, the material can be controlled to be offline at the second reflow position 315, and after the material is processed, the material can be re-online at the first reflow position 314, and the material is controlled to flow through the photographing process 302 before welding, the low-voltage insulation process 303, the CCS assembling process 304 to reach the BSB welding process 305, and the welding operation is re-performed on the material in the BSB welding process 305.

When the target material needs to be refluxed, a reflux request of the target material can be sent to the upper computer, and the upper computer controls the target material to flow into the target procedure from the target reflux position after receiving the reflux request of the target material.

In response to the reflow request of the target material, the manner of controlling the target material to flow into the target process from the target reflow position may be that, after receiving the reflow request of the target material, the target material is controlled to be fed from the target reflow position, and then the target material is controlled to be transferred to the target process through a conveyor belt of the production line.

The method for triggering the reflow request of the target material may be that the target reflow position includes a reflow waiting area, the upper computer detects whether the target material exists in the reflow waiting area in real time, and triggers the reflow request of the target material after detecting that the target material exists in the reflow waiting area. Optionally, the reflow request of the target material may also be sent by the user to the upper computer.

S802, acquiring material information of the target material according to a processing request of the target material in a target process.

After the target material enters the target process, a sensor in the target process senses the target material, the sensor sends the event of sensing the target material to an upper computer, namely the target material triggers a processing request in the target process, and the upper computer can acquire the material information of the target material after receiving the processing request of the target material in the target process.

If the material information includes BSB repair welding, a standard program function block corresponding to the BSB repair welding can be called to perform BSB repair welding on the target material.

Optionally, the material information of the target material may further include a specific position to be repair welded, and the upper computer maps the specific position to be repair welded to a standard program function block of BSB repair welding, so as to implement repair welding operation on the target material.

In the material reflow method provided by the embodiment of the application, in response to a reflow request of a target material, the target material is controlled to flow into a target procedure from a target reflow position, material information of the target material is obtained according to a processing request of the target material in the target procedure, and then the target material is subjected to reflow control according to the material information of the target material and a standard program function block corresponding to the pre-configured target procedure; the production line of the target material comprises a plurality of backflow positions, and the target backflow positions are determined according to the material state of the target material.

The feeding area of the target process may be a starting position of the target process, and is used for feeding the target material into the target process, i.e. each process of the production line has a feeding area; for example, the loading area of the BSB weld may be an area that feeds the target material into the weld location.

Whether the feeding area has the target tray or not can be detected through an inductor on the feeding area of the target process, and after the inductor senses that the feeding area of the target process has the target tray, the inductor can send the sensing result to the upper computer; the material on the target tray is the target material.

Before the target material is transported on the production line through the target tray, the target tray and the target material can be bound, tray information of the target tray and material information of the target material are stored in a database, and tray information of a plurality of trays and material information of corresponding materials are stored in the database.

Optionally, the tag on the target tray may also be an electronic tag, that is, a carrier code, and the tag stores material information of the target material, so that the tag on the target tray is identified, and the manner of obtaining the material information of the target material may also be that the radio frequency device in the feeding area is controlled to scan the tag on the target tray, so as to read the material information of the target material.

And the feeding area of each process is provided with a radio frequency device, and the radio frequency device is used for reading the material information stored in the label of the target tray and uploading the material information to the upper computer when the material reaches the corresponding process.

Specifically, electromagnetic waves are emitted by a reader-writer in the radio frequency equipment controlling the feeding area, the electromagnetic waves form an electromagnetic field, the electromagnetic waves cover the range of the label of the target tray, and when the label of the target tray is in the electromagnetic field, an antenna inside the label senses the electromagnetic waves and converts the electromagnetic waves into electric energy. The chip in the tag activates itself by using the electric energy received by the antenna, and transmits the data stored in the chip to the reader-writer of the radio frequency equipment, the reader-writer converts the received data into digital signals, decodes, verifies and the like the digital signals, finally converts the digital signals into readable data, and transmits the readable data to the upper computer, and the upper computer determines the data sent by the radio frequency equipment as the material information of the target material.

In the method, before the label of the target tray is identified, the target tray is detected, whether the target tray is in a feeding area is judged, and material information stored in the label of the target tray can be acquired only after the target tray is in the feeding area, so that invalid reading and error reading of radio frequency equipment are reduced, and the accuracy of the material information of the target material is improved.

Because the material flowing into the target process is likely to be a reflow material or a normal production material, the normal production material can represent the material processed according to the preset production line process in the production process, after the upper computer acquires the material information of the target material, the upper computer can detect the material mode of the target material first, judge whether the target material is the reflow material or the normal production material, and in the case that the material mode is the reflow material, the reflow control is performed on the target material according to the material information of the target material and the standard program function block corresponding to the preset target process.
