[0037] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0038] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0039] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0040] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0041] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0042] The present disclosure provides a fully automatic production line (hereinafter referred to as production line), such as Figure 1 As shown, the production line 1000 may include a control center 1100, a tool changing unit 1200, and a plurality of production equipment 1300-1 to 1300-N. The tool may circulate among the plurality of production equipment via a conveyor belt.

[0043] Specifically, the first production equipment among the multiple production equipment places the product to be processed in the incoming tooling, which is then processed sequentially by the production equipment 1300-2 to 1300-N-1 between the first production equipment 1300-1 and the last production equipment 1300-N. After the product carried on the tooling is taken out by the last production equipment 1300-N among the multiple production equipment, it will flow back to the first production equipment 1300-1 among the multiple production equipment to place the product to be processed.

[0044] In one embodiment, the tooling of the first product and the second product can be completely different; the first product and the second product can also share some tooling (i.e., the parent tooling) and use corresponding child tooling independently. In this way, it is convenient for the tooling replacement unit to replace the tooling during production change, reduce the labor burden of manual handling of the tooling, and facilitate the rapid and automatic switching of the tooling.

[0045] The present disclosure provides a production line control method. Figure 2As shown, the production line control method may include steps S2100 to S2300 as shown below:

[0046] Step S2100, in response to the user executing a production change operation to replace a first product processed on the production line with a second product, the control center issues a production change instruction to the production equipment and tooling replacement unit on the production line.

[0047] In this embodiment, the user may first input the product information of the second product in the control center, and then perform a production change operation, that is, perform a production change operation to replace the first product processed on the production line with the second product.

[0048] In response to the production change operation, the control center may include the product information of the second product in the production change instruction issued. The product information of the second product included in the production change instruction may be the same as or different from the product information of the second product input into the control center by the user, and is not limited here. For example, the product information of the second product included in the production change instruction and the product information of the second product input into the control center by the user may both be the product category identifier of the second product. For another example, the product information of the second product included in the production change instruction may be the tooling variety number information of the second tooling corresponding to the second product, and the product information of the second product input into the control center by the user may be the product category identifier of the second product.

[0049] In step S2200, the tooling replacement unit switches the first tooling corresponding to the first product that is running back on the production line to the second tooling corresponding to the second product in response to the production change instruction.

[0050] In this embodiment, the tool changing unit switches the first tool running from the last production equipment to the first production equipment on the production line to the second tool in response to the production change instruction.

[0051] When the first product and the second product share a parent tooling and use corresponding sub-tooling independently, the sub-tooling corresponding to the first product is the first tooling, and the sub-tooling corresponding to the second product is the second tooling.

[0052] In one embodiment, the second tool may be provided with tool type number information corresponding to the second product.

[0053] In another embodiment, the tooling replacement unit can write the tooling variety number information corresponding to the second product into the second tooling through Radio Frequency Identification (RFID) when switching the first tooling to the second tooling, and then release the second tooling to allow the second tooling to flow to the first production equipment in the production line.

[0054] In one embodiment, if the first tooling corresponding to the first product is exactly the same as the tooling corresponding to the second product, the tooling replacement unit switches the first tooling corresponding to the first product that is running back on the production line to the second tooling corresponding to the second product. The tooling type number information of the tooling may be switched, specifically, the tooling type number information corresponding to the first product is switched to the tooling type number information corresponding to the second product.

[0055] Correspondingly, the first tooling is also provided with tooling variety number information corresponding to the first product.

[0056] Step S2300, the production equipment responds to the production change instruction, and when it is identified that the tooling entering the production equipment is the first second tooling, controls the outflow of the first second tooling and shuts down to replace the material corresponding to the second product.

[0057] In this embodiment, the production equipment may identify whether the tooling entering the production equipment is the first tooling or the second tooling. Specifically, the production equipment may read the tooling variety number information of the tooling entering the production equipment through RFID, and compare the read tooling variety number information with the product information of the second product included in the production change instruction. If the two match, it can be determined that the tooling entering the production equipment is the second tooling; if the two do not match, it can be determined that the tooling entering the production equipment is the first tooling.

[0058] Furthermore, when the production equipment identifies that the tooling entering the production equipment is the first second tooling, that is, the tooling that last entered the production equipment was the first tooling and the tooling that enters the production equipment this time is the second tooling, the production equipment controls the first second tooling to flow out of the current production equipment so that the first second tooling enters the next production equipment in the production line.

[0059] In this embodiment, the production equipment does not perform material processing based on the first identified second tooling.

[0060] In this embodiment, the production equipment is shut down to replace the material corresponding to the second product when the first second tooling flows out of the current production equipment.

[0061] Furthermore, when the first second tooling flows out of a production device, the next production device may not have entered the production device yet, or may have entered the production device, which is not limited here.

[0062] Furthermore, the production equipment is shut down, that is, the production equipment stops processing materials.

[0063] In this embodiment, the production equipment may automatically replace the material corresponding to the second product, or may call an operator to manually replace the material corresponding to the second product.

[0064] When the production equipment automatically changes materials, the control center can call an automated guided vehicle (AGV) to automatically remove the material corresponding to the first product on the production equipment through the AGV and replace it with the material corresponding to the second product.

[0065] When manually replacing materials, the production equipment can call the control center, and the control center can call the operator. The operator can quickly reach the production equipment to replace the material based on the information received. Or the production equipment can directly call the operator to reach the production equipment to replace the material. When manually replacing materials, the operator will confirm the replacement one by one according to the Standard Operating Procedure (SOP) issued by the digital IOT; after the replacement is completed, the operator clicks the Replacement Complete button on the control center. The control center then feeds this information back to each production equipment on the production line.

[0066] In one embodiment, the first product and the second product may be two completely different products, or the first product and the second product may be product forms of the same finished product at different processing stages. Correspondingly, the first material and the second material may be materials required for processing different products, or the first material and the second material may be materials required for the same product at different processing stages.

[0067] Through the embodiments of the present disclosure, the tooling replacement unit responds to the production change instruction and switches the first tooling corresponding to the first product that is running back on the production line to the second tooling corresponding to the second product, thereby realizing fast and automatic switching of tooling and reducing the labor load and labor cost of manual handling of tooling; the production equipment responds to the production change instruction and identifies the tooling entering the production equipment, and when it is identified that the tooling entering the production equipment is the first second tooling, it controls the outflow of the first second tooling and stops the machine to replace the material corresponding to the second product, thereby realizing fast and automatic production change of the production line and improving the production efficiency of the production line.

[0068] In one embodiment of the present disclosure, the method may further include: when the first production equipment identifies that the tooling entering the production equipment is the first second tooling, the first production equipment writes a second setting identifier into the first second tooling; the second production equipment identifies whether the tooling entering the second production equipment is the first second tooling based on the second setting identifier; wherein the first production equipment is the first production equipment in the production line, and the second production equipment is any production equipment in the production line except the first production equipment.

[0069] In this embodiment, the first production equipment may write the second setting identifier into the first second tooling through RFID, and the second production equipment may read the second setting identifier of the tooling entering the second production equipment through RFID.

[0070] Through this embodiment, it is possible for the subsequent second production equipment to quickly identify whether the tool entering the second production equipment is the first second tool.

[0071] In one embodiment of the present disclosure, the method also includes: after the production equipment has replaced the material, obtaining second processing parameters of the production equipment corresponding to the second product from the control center, and entering a process of producing the second product according to the second processing parameters and the material corresponding to the second product.

[0072] In this embodiment, when the production equipment replaces the material corresponding to the first product with the material corresponding to the second product, the production equipment will call the control center to switch the parameters. Specifically, the production equipment notifies the control center of the replacement of the material through a signal handshake, and the control center sends the second processing parameter of the production equipment corresponding to the second product to the production equipment, thereby realizing the automatic switching of the processing parameters in the production equipment.

[0073] After replacing the material and obtaining the second processing parameters, the production equipment enters the production process of the second product and processes the material corresponding to the second product on the second tooling according to the second processing parameters.

[0074] Through this embodiment, automatic production change of production equipment can be achieved without manual operation, thus reducing labor costs and improving production efficiency.

[0075] In one embodiment of the present disclosure, the method further includes: the production equipment switches the production mode of the production equipment to a second production mode in response to a production change instruction, and the second production mode is a production mode in which materials are taken after the tooling is in place.

[0076] In this embodiment, the second production mode is a low-speed production mode, in which the production equipment needs to wait until the tooling is in place before taking the material. In this way, it can be ensured that the material processing quantity is matched according to the tooling, and that there is no excess material in each buffer mechanism of the production equipment, which is convenient for subsequent material return.

[0077] In one embodiment of the present disclosure, the method further includes: when the production equipment enters the process of producing the second product, switching the production mode of the production equipment to the first production mode, the first production mode being a production mode of first taking materials and then waiting for the tooling to be in place.

[0078] In this embodiment, the first production mode is a high-speed production mode, in which the production equipment first takes the material and then waits for the tooling to be in place, so that the processing efficiency of the production equipment can be improved.

[0079] In one embodiment of the present disclosure, the method further includes: the production equipment responds to the production change instruction, and when identifying that the tooling entering the production equipment is the first tooling, the production equipment continues to process the first product.

[0080] In this embodiment, when it is identified that the tooling entering the production equipment is the first tooling, the production equipment that continues to process the first product may include at least the second production equipment and may also include the first production equipment.

[0081] In one embodiment of the present disclosure, the method further includes: the first production equipment responds to the production change instruction, and upon identifying that the tooling entering the production equipment is the first tooling, controls the first tooling to flow out of the first production equipment, and does not process the material corresponding to the first product based on the first tooling.

[0082] In one embodiment of the present disclosure, the method may further include: when the first production equipment identifies that the tooling entering the first production equipment is the first tooling, the first setting identifier is written into the tooling entering the first production equipment; when the second production equipment identifies that the tooling entering the second production equipment has the first setting identifier, the second production equipment controls the tooling with the first setting identifier to flow out of the second production equipment, and does not process the material corresponding to the first product based on the tooling with the first setting identifier.

[0083] In this embodiment, the first production equipment may write the first setting identifier into the tooling entering the first production equipment through RFID, and the second production equipment may read the first setting identifier in the tooling entering the second production equipment through RFID.

[0084] When the first production equipment identifies that the tooling entering the production equipment is the first tooling, it can determine that the first tooling is the first tooling that does not require material processing, and write a first setting identifier in the first tooling; the second production equipment identifies whether the tooling entering the second production equipment is the first tooling that does not require material processing based on the first setting identifier, and when it identifies that the tooling entering the second production equipment is the first tooling that does not require material processing, it controls the first tooling to flow out of the second production equipment, and does not process the material corresponding to the first product based on the first tooling.

[0085] Through this embodiment, when the production line receives a production change operation from the user, only the first product in the processing process in the production line will be produced, and material processing will no longer be performed based on the first tooling in the reflow process, so as to ensure the quantity of the first product produced.

[0086] The present disclosure also provides a production line control system.
