Description

Technical Field

[0001] The invention belongs to the technical field of SMT, and in particular relates to a single-track and double-track switching method and system for an SMT production line. Background Art

[0002] SMT is surface mount technology, which is the most popular technology and process in the current electronic assembly industry. It is a method of installing pinless or short-lead surface mount components on the surface of printed PCB boards.

[0003] When there is a dual-track device on the SMT production line, the dual-track device needs to switch the track production mode (single-track mode or dual-track mode) according to the size of the substrate to be produced or the needs of production management. For example: when the substrate is large in size, only the single-track mode can be used for production; when the substrate is small in size, the dual-track mode is used for production on both tracks at the same time, which is more efficient.

[0004] However, currently, in order to switch the track production mode of dual-track equipment, it is necessary to first shut down the equipment in production, clear the production substrate on the production line, and then manually change the single-track or double-track production mode of the equipment. In addition, since the configuration information of the equipment (such as the track mode, whether the track mode is single-track or dual-track) changes, it is also necessary to manually change the equipment configuration information in the upper system before entering production. Since all dual-track equipment needs to repeat this operation, this method has a long downtime, which greatly affects production efficiency. In order to solve the above technical problems, the present invention is derived from this. Summary of the invention

[0019] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0020] See also Figures 1 to 5 An embodiment of the present invention provides a single-track and double-track switching system for an SMT production line, including a production line management system 10, which is communicatively connected with all devices in the production line.

[0021] Specifically, the production line management system 10 includes six functional modules, namely, an operation / information entry processing module 15, a single-track and double-track switching module 11, an equipment configuration information management module 12, a production machine type switching module 13, a first communication module 14, and a display processing module 16. The operation / information entry processing module 15, the single-track and double-track switching module 11, the equipment configuration information management module 12, the production machine type switching module 13, and the display processing module 16 establish a communication connection through the first communication module 14.

[0022] As for the role of each functional module, specifically, the operation / information input processing module 15 is responsible for receiving the production program and the track 23 mode information required for production manually or by a barcode reader or a customer's host computer, and notifying the remaining modules of the acquired information.

[0023] The single-track and double-track switching module 11 compares the acquired designated track 23 mode with the current track 23 mode to determine whether it is necessary to execute the track 23 mode switch. When switching is required, the first communication module 14 is used to notify each target device to execute the corresponding track 23 mode switch, and receive and save the device status after switching (the device status here is the track 23 status after switching).

[0024] The equipment configuration information management module 12 matches the track 23 configuration of all equipment in the production line (i.e., single-track production mode or dual-track production mode) according to the switching result, and notifies the production machine type switching module 13 of the configuration result.

[0025] After receiving the track 23 configuration information of the equipment in the production line, the production machine type switching module 13 notifies the target equipment to download the production program for the production of the new batch of products through the first communication module 14 .

[0026] The first communication module 14 is responsible for collecting the result information between each module and notifying each device in the production line, and collecting the processing results of each target device to notify the single-track and dual-track switching module 11, the equipment configuration information management module 12, the production machine model switching module 13 and the display processing module 16.

[0027] The display processing module 16 collects the device status of each object device in the production line through the first communication module 14 (the device status here is the track 23 switching status, including at least waiting for switching, switching, switching completed and error in switching) and displays the device status of each object device, the current designated track 23 mode and the track 23 mode before and after switching. Preferably, the display processing module 16 also displays the current abnormal information of each device in the production line. It is convenient for the operator to intuitively understand the specific abnormal equipment and specific abnormal problems, and can timely eliminate abnormalities based on the abnormal display information.

[0028] For the equipment in the production line, it includes dual-track equipment 20 (which can switch between single-track production mode and dual-track production mode) Figure 3 M3, M4, ..., M7 are exemplified in the example, that is, it can perform single-track production, such as a substrate 30 with a larger area, or it can perform dual-track production, such as a substrate 30 with a smaller area, on two tracks 23 at the same time. It can also include both dual-track equipment 20 and equipment with only a single track 23 production mode (for the sake of distinction, it is described as a single track equipment, Figure 3 In the example, M1 and M2 are arranged side by side on both sides perpendicular to the product conveying direction. Since the single-track equipment is simpler in structure and lower in cost than the double-track equipment 20, and considering the flexibility, the equipment in the general production line includes single-track equipment and double-track equipment 20. For example, Figure 3 As shown, the equipment in the production line of the embodiment of the present invention includes both double-track equipment 20 and single-track equipment. Usually, the single-track equipment is located at the starting end of the product conveying direction, and the double-track equipment 20 is arranged at the rear of the product conveying direction in the production line. The embodiment of the present invention is mainly aimed at the double-track equipment 20 in the production line, so only the double-track equipment 20 is discussed here. Figure 2 As shown, all dual-track devices 20 in the embodiment of the present invention include a track 23 switching control module 21 and a second communication module 22. The second communication module 22 is connected to the first communication module 14. The track 23 switching control module 21 is connected to the single-dual track switching module 11, the equipment configuration information management module 12, the production machine type switching module 13, and the display processing module 16 in the production line management system 10 through the second communication module 22 and the first communication module 14. The track 23 switching control module 21 is used to control the device to execute the track 23 switching after receiving the track 23 switching information sent by the production line management system 10 and feedback the switching status to the equipment configuration information management module 12 and the display processing module 16 after the track 23 mode switching is completed.

[0029] For the arrangement of the track 23 of the double track device 20, as Figure 4 and Figure 5As shown, any double-track device 20 includes four tracks 23 arranged in parallel and perpendicular to the product conveying direction, at least the two middle adjacent tracks 23 of the four tracks 23 are movable (that is, in addition to the two middle tracks 23 being movable, the middle track 23 plus one or two side tracks 23 can also be movable), and any double-track device 20 has a double-track 23 production mode and a single-track 23 production mode, wherein in the double-track 23 production mode, the two middle adjacent tracks 23 are arranged at intervals and are respectively arranged at intervals with the two outer tracks 23 to form two track 23 lines (such as Figure 4 In the single track 23 production mode, the two adjacent tracks 23 in the middle are close to each other and close to the track 23 on one side and are separated from the track 23 on the other side to form a single track 23 line ( Figure 5 The three rails 23 at the top or rear are close to each other).

[0030] See also Figures 1 to 5 Another embodiment of the present invention provides a single-track and double-track switching method for an SMT production line. Based on the switching system of the above embodiment, for the convenience of description, the first double-track device 20 ( Figure 3 In the example, M3) is a first target device. Specifically, the switching method includes the following steps: The production line management system 10 obtains the designated track 23 pattern of the batch of products from the product information of the next batch of products to be produced; The production line management system 10 compares the current track 23 pattern of the first object device with the designated track 23 pattern of the next batch of products to be produced; If they are consistent, it is determined that there is no need to switch the track 23 mode, and the production line management system 10 notifies the remaining dual-track devices 20 to download the production data of the new batch and notifies to start production; If they are inconsistent, the current target device is notified to switch to the specified track 23 mode; After the track 23 mode switching of the current object device is completed, the new device configuration information (at least including the track 23 mode (i.e., single-track mode or dual-track mode), because the dual-track devices 20 in the production line are devices corresponding to different processes and have different functions, such as device names, categories, identifiers, program identifiers, etc. are all different, so the device configuration information here can also include, for example, device names, device identifiers, device categories, communication methods, IP addresses, production program identifiers, etc.) is fed back to the production line management system 10; After the production line management system 10 monitors the track 23 mode switching of the current target device, the device configuration information of the current target device is updated; After completing the switching of the track 23 mode and updating the equipment configuration information, the production line management system 10 notifies the current target equipment to download the production data and notifies to start production. At the same time, the production line management system 10 instructs the target equipment behind the current target equipment to complete the switching of the track 23 mode in sequence (that is, along the product conveying direction, i.e., Figure 3 In the direction from left to right shown, the second object device ( Figure 3 The example is M4), the third object device ( Figure 3 M5 is exemplified in the figure) and the like complete the track 23 switching in sequence after receiving the track 23 mode switching information sent by the production line management system 10).

[0031] Preferably, before the current object device receives the notification from the production line management system 10 to switch to the designated track 23 mode, if there are products produced in the previous batch in the current object device, the products in the device need to be discharged in sequence, and then the track 23 mode is switched to the designated track 23 mode.

[0032] In the single-track and double-track switching method and system of the SMT production line of the embodiment of the present invention, the production line management system monitors the target equipment and instructs the double-track equipment to automatically switch between the single-track production mode and the double-track mode according to the instruction information. At the same time, the equipment configuration information in the upper system is automatically updated according to the equipment configuration information after the track production mode is switched fed back by the double-track equipment. Then, the target equipment is instructed to download the production data and enter production. During the production process, there is no need to stop the machine for track mode switching, and no manual operation is required. The single-track and double-track production modes can be fully automatically switched, which greatly improves production efficiency and reduces the skill requirements for operators.

[0033] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention.
