Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0062] In modern manufacturing, production lines need to switch products of different specifications according to production plans, which requires corresponding switching of matching tooling (jigs). In the prior art, tooling switching usually relies on manual operation, which is inefficient and prone to errors, and requires shutdown for tooling switching, affecting production efficiency. Therefore, it is particularly important to design a push unit that can automatically switch tooling.

[0063] In view of this, the present invention proposes a control method for a production system, please refer to Figures 1 to 5 , which is an embodiment of the control method of the production system proposed in this application, the control method of the production system will be described in detail below with reference to specific drawings.

[0064] See also Figures 1 to 5The production system 1000 includes a production line 200 and a tooling scheduling device 100. The tooling scheduling device 100 includes a storage structure 1 and a transfer structure 2. The storage structure 1 is used to store a variety of tooling 3. The transfer structure 2 is arranged between the production line 200 and the storage structure 1.

[0065] The control method of the production system 1000 includes the following steps:

[0066] S100: Obtain the three types of required tooling and determine whether they are consistent with the three types of tooling on the production line 200;

[0067] S200: If they are inconsistent, control the transfer structure 2 to transfer the tooling 3 on the production line 200 to the storage structure 1, and then transfer the required tooling 3 at the storage structure 1 to the production line 200.

[0068] In the technical solution of the present invention, the production system 1000 includes a production line 200 and the tooling scheduling device 100. Specifically, the tooling scheduling device 100 includes the storage structure 1 and the transfer structure 2. The storage structure 1 is used to store a variety of tools 3, and the transfer structure 2 is used to transfer the tools 3 between the storage structure 1 and the production line 200. Based on the above structure, when the production system 1000 obtains the types of tools 3 required for the subsequent processing flow, the tooling 3 being used on the production line 200 is transferred. The types are compared. If the required type of tooling 3 is different from the type of tooling 3 in use, the transfer structure 2 is controlled to transfer the tooling 3 in use on the production line 200 to the storage structure 1 for storage, and then the required tooling 3 stored in the storage structure 1 is transferred to the production line 200, thereby completing the automatic switching of the tooling 3 on the production line 200. No manual operation is required, which is not prone to errors and does not require shutdown for tooling 3 switching, thereby making the tooling 3 switching efficient, and thereby making the production efficiency of the production system 1000 high.

[0069] Specifically, the storage structure 1 includes a plurality of storage pipelines 11, each of the storage pipelines 11 having an access end close to the production pipeline 200;

[0070] The step S200 includes:

[0071] S210: If they are not consistent, control the transfer structure 2 to transfer the tooling 3 on the production line 200 to the access end of the corresponding storage line 11;

[0072] S220 : Control the transfer structure 2 to move to the access end of the storage line 11 corresponding to the required tooling 3 , and transfer the required tooling 3 to the production line 200 .

[0073] The specific form of the storage structure 1 is not limited. It can be an open storage platform that records the access point during access to record whether there is a tool 3 at the corresponding point and the specific type of the tool 3 when the tool 3 exists at the point; it can also be a vertical warehouse structure with multiple movable storage platforms inside, which can move inside the vertical warehouse and between the vertical warehouse exit. The vertical warehouse structure automatically records whether there is a tool 3 on each storage platform and the specific type of the tool 3 when the tool 3 exists. In this way, when the tool 3 needs to be stored, the tool 3 only needs to be transported to the exit of the vertical warehouse structure through the transfer structure 2, placed on the empty storage platform at the exit, and the required tool 3 is taken away from the storage platform carrying the required tool 3 at the exit. Then, the vertical warehouse structure can automatically retract the two storage platforms. Platform for positioning and storage; it can also be the multiple storage assembly lines 11 structure proposed in this embodiment, which is similar to the vertical warehouse structure proposed above, but the implementation form is different, the flexibility is poor, but the structure is simple and the control logic is simple. Specifically, multiple storage assembly lines 11 are set to carry multiple tooling 3 respectively. Generally, one type of tooling 3 is stored on one storage assembly line 11, and each storage assembly line 11 has a storage and access end. When the tooling 3 needs to be stored, the tooling 3 placed on the storage and access end of the transfer structure 2 is driven to be retracted inwardly, and when the tooling 3 needs to be taken out, the tooling 3 on the storage assembly line 11 is driven to move to the storage and access end for the transfer structure 2 to pick up. The structure is simple and the control logic is simple, the fault tolerance rate is high, and the performance is stable. Of course, the above is a detailed explanation of storing a type of tooling 3 on each of the storage lines 11. In fact, the tooling 3 stored on the storage lines 11 can also be different, as long as the storage order of different tooling 3 can be recorded or the type of stored tooling 3 can be detected in real time, and then the matching transfer structure 2 can be used to pick up the tooling 3.

[0074] Furthermore, the tooling scheduling device 100 further includes an identification structure disposed on the transfer structure 2, and the identification structure is used to identify the type of tooling 3;

[0075] The step S100 includes:

[0076] S110: Obtain three types of required tooling;

[0077] S120: Obtain the three types of tooling on the production line 200 identified by the identification structure, and determine whether they are consistent with the three types of tooling required.

[0078] It is understandable that the type of tooling 3 on the production line 200 can be confirmed by obtaining the information stored in the system, but this method has certain disadvantages. When the production process is abnormal and the storage information does not match the production information, it will cause abnormal confirmation of the type of tooling 3. At this time, if the storage structure 1 also uses the information storage method to access the tooling 3, it will cause the overall use of the subsequent tooling 3 to be incorrect, and then cause the production system 1000 to be abnormal. Therefore, in this embodiment, the identification structure is provided on the transfer structure 2 to identify the type of tooling 3 on the production line 200, and then accurately perform operations such as the replacement of tooling 3, avoid the abnormal situation described above, and make the operation of the tooling scheduling device 100 more stable. Based on the identification structure, it can be further configured to not only detect the type of tooling 3, but also to be able to identify the code of each tooling 3, so as to realize the above-mentioned function of distinguishing the types of tooling 3, and also realize the offline function of abnormal tooling 3, that is, when the tooling 3 is marked as abnormal at the processing station in the production system 1000, the tooling 3 can be captured by the transfer structure 2 when it is transferred to the tooling scheduling device 100, and then the abnormal tooling 3 is removed from the production line 200 through the transfer structure 2, so that subsequent staff can perform repair operations. It should also be noted here that the storage structure 1 can also be provided with a repair line, which is parallel to the other storage lines 11, but it is mainly used to store abnormal tooling 3 removed from the production line 200, so that the staff can handle them uniformly for a period of time without having to wait at the tooling scheduling device 100 to remove the abnormal tooling 3 in time.

[0079] Further, the production line 200 includes a main pipeline 201 and a return pipeline 202, the transfer structure 2 includes a main cache pipeline 21, a return cache pipeline 22 and a transfer mechanism 23, the main cache pipeline 21 is arranged at the inflow end of the main pipeline 201, the return cache pipeline 22 is arranged at the outflow end of the return pipeline 202, the main cache pipeline 21 is used to transport the tooling 3 to the main pipeline 201, the return pipeline 202 is used to return the tooling 3 on the main pipeline 201 to the return cache pipeline 22, and the identification structure includes a first identification structure arranged on the return cache pipeline 22;

[0080] After step S100, the method further includes the following steps:

[0081] S130 : If they are consistent, the transfer mechanism 23 is controlled to transfer the tooling 3 that flows back through the return pipeline 202 to the return cache pipeline 22 to the main cache pipeline 21 , and the main cache pipeline 21 is controlled to transport the tooling 3 to the main pipeline 201 again.

[0082] It can be understood that the tool scheduling device 100 can be a structure completely independent of the production line 200, that is, the tool scheduling device 100 is not set up, and the production line 200 is also a complete circulation structure. In this case, the tool scheduling device 100 is set on the side of the production line 200, so that the tool 3 can be taken and placed on the production line 200 through the transfer structure 2 to achieve the functions described above. In this embodiment, the tooling scheduling device 100 is configured to directly participate in the circulation of the production line 200. Specifically, the production line 200 includes the main pipeline 201 and the return pipeline 202. The transfer structure 2 includes the main cache pipeline 21, the return cache pipeline 22 and the transfer mechanism 23. When the transfer structure 2 does not switch the tooling 3, it is also necessary to receive the tooling 3 returned from the return pipeline 202 through the return cache pipeline 22, and transfer it to the main cache pipeline 21 through the transfer structure 2, and then transport it to the main cache pipeline 201 from the main cache pipeline 21, so as to realize the complete circulation of the production line 200. With such arrangement, the transfer structure 2 can participate in the flow process of the tooling 3 of the production line 200. On the one hand, the type of tooling 3 can be identified by the first identification structure on the reflux buffer line 22 to avoid production abnormalities caused by the mixing of different tooling 3. On the other hand, combined with the tooling 3 rework process described above, abnormal tooling 3 can be identified in real time and removed from the production line 200 in time to avoid affecting the normal production process. On the other hand, when switching tooling 3, each tooling 3 needs to stay at the transfer structure 2, and compared with the normal flow function of the same tooling 3, the switching function only increases the transfer function of the transfer machine. The control logic design of the mechanism 23 is relatively simple, and the situation of missing the tool 3 without switching will not occur. On the other hand, when the production order is switched, due to the above structural setting, the identification of the tool 3 and the picking up of the tool 3 by the transfer mechanism 23 are normalized functions. If the type of tool 3 required is consistent with the type of tool 3 on the production line 200, the transfer mechanism 23 does not need to perform additional actions, and the identification and confirmation of the tool 3 can be completed, and the tool 3 can flow into the production line 200 again, eliminating the tool 3 identification and switching process of the same tool 3 used in different orders, thereby improving efficiency.

[0083] Furthermore, the identification structure also includes a second identification structure provided on the transfer mechanism 23;

[0084] The step S200 includes:

[0085] S230: Obtaining the pre-stored position information of the required tooling 3 in the storage structure 1;

[0086] S240: Control the transfer structure 2 to pick up the tool 3 at the position information, and obtain the actual tool 3 type of the tool 3;

[0087] S250: Determine whether the three types of actual tooling are consistent with the three types of required tooling;

[0088] S260 : If they are consistent, control the transfer structure 2 to transfer it to the main cache pipeline 21 , and control the main cache pipeline 21 to transport the tooling 3 to the main pipeline 201 .

[0089] On the basis of the first identification structure, the second identification structure is also arranged on the transfer mechanism 23, and its main purpose is to avoid the situation that when the tooling 3 on the storage structure 1 is abnormally placed, the transfer mechanism 23 directly transports the abnormal tooling 3 to the production line 200, so as to avoid the abnormal situation of the production system 1000, and when the transfer mechanism 23 recognizes that the picked up tooling 3 is different from the tooling 3 type recorded in the corresponding position information in the storage structure 1, the picked up erroneous tooling 3 can be put back to the storage position corresponding to the storage structure 1, and the corresponding relationship between the storage position and the tooling 3 can be re-recorded to achieve the purpose of error correction, so that it has an automatic error correction function and good automation performance.

[0090] See also Figure 7 The present application also proposes a tooling scheduling device 100, which is applied to a production system 1000, wherein the tooling scheduling device 100 includes a storage structure 1 and a transfer structure 2, wherein the storage structure 1 is used to store a variety of tools 3; the transfer structure 2 is used to be arranged between the production line 200 and the storage structure 1, so as to transfer the tools 3 between the production line 200 and the storage structure 1. The main structure and functions of the tooling scheduling device 100 have been described in detail above, so they will not be repeated here one by one.

[0091] Further, the storage structure 1 includes a plurality of storage lines 11, and each storage line 11 is provided with a plurality of storage areas at intervals along its flow direction, and each storage area is used to store one tool 3. The storage structure 1 including a plurality of storage lines 11 is also described in detail above. Based on the structural features of the plurality of storage lines 11 described above, the present embodiment also points out that a plurality of storage areas are provided on the storage line 11, that is, the storage line 11 is artificially partitioned so that one storage area corresponds to the storage of one tool 3. On the one hand, the tool 3 on the storage line 11 is placed more neatly, which is convenient for care and for the transfer structure 2 to pick up. On the other hand, the movement distance of the storage line 11 can be fixed, that is, a multiple of the length of the storage area, so as to facilitate the control of the activity of the storage line 11, and the activity precision is higher.

[0092] In addition, each of the storage lines 11 has a relative access end and a storage end, and the access end is used to be arranged close to the production line 200: wherein the access end is provided with a first detection device, and the storage end is provided with a second detection device. The storage line 11 has a storage upper limit, and the system record control can be used to avoid the storage of tooling 3 exceeding the storage upper limit of the storage line 11, but the reliability is obviously poor. Therefore, in this embodiment, the first detection device is provided at the access end of the storage line 11 to detect whether there is tooling 3 in the storage area close to the access end, and it can also be used as an auxiliary detection for the transfer structure 2 to pick up tooling 3 to avoid empty grabbing. At the same time, the storage end of the storage line 11 is provided with the second detection device to avoid the storage of tooling 3 on the storage line 11 exceeding the upper limit and continuing to run toward the storage end, causing the tooling 3 to fall.

[0093] In addition, each storage pipeline 11 stores the same tool 3. The storage pipeline 11 can store the same tool 3 or different tool 3, which has been described in detail above and will not be repeated here. In this embodiment, each storage pipeline 11 is set to store only the same tool 3, which is more convenient for tool 3 management, and the control logic of the tool scheduling device 100 is simpler.

[0094] In addition, the transfer structure 2 includes a main cache pipeline 21, a return cache pipeline 22 and a transfer structure 2. The main cache pipeline 21 is used to be set at the inflow end of the main pipeline 201 of the production line 200 to input the tool 3; the return cache pipeline 22 is used to be set at the outflow end of the return pipeline 202 of the production line 200 to receive the tool 3; the transfer mechanism 23 is used to transfer the tool 3 between the main cache pipeline 21, the return cache pipeline 22 and the storage pipeline 11. The tool scheduling device 100 can be independent of the production line 200, or it can participate in the return line of the production line 200. It has been described in detail above. In this embodiment, the tool scheduling device 100 is mainly set to participate in the return line of the production line 200, so as to have the various beneficial effects described above and meet the design requirements.

[0095] Specifically, the storage structure 1 includes a plurality of storage pipelines 11, and the plurality of storage pipelines 11, the main cache pipeline 21, and the reflow cache pipeline 22 are all extended along the first horizontal direction. The transfer mechanism 23 includes a transfer pipeline 231 that can be movably arranged along the second horizontal direction, and the transfer pipeline 231 is extended along the first horizontal direction. The specific structural setting of the transfer mechanism 23 can be various, for example, it can be set as a manipulator structure, a three-axis movable clamping structure, etc., which can realize the transfer of the tooling 3.
