Description

Technical Field

[0001] This invention belongs to the field of integrated circuit packaging and relates to an automated assembly production line for integrated circuit packaging, specifically to an automated production line and method for multi-chip components at multiple workstations. Background Technology

[0002] The statements in this section are provided only as background information in relation to this disclosure and may not constitute prior art.

[0003] Multi-chip modules (MCMs) are microelectronic components that assemble bare chips, discrete components, and other devices onto a high-density interconnect substrate, interconnect them, and package them to achieve specific functions. They are characterized by high density, high performance, and high reliability. Typical assembly processes for MCMs include reflow soldering, chip bonding, eutectic bonding, flip-chip bonding, and wire bonding. Currently, some assembly processes can be automated, such as with automatic dispensing machines, automatic chip mounters, and automatic wire bonding machines. To improve assembly efficiency and reduce manpower on production lines, connecting and configuring equipment into automated production lines has become a hot research topic in the industry.

[0004] Chinese Patent CN 114803397 A discloses an automated production line and control method. It transports materials to be processed to the processing equipment via a transport track and controls the execution of each device in the production line through a control system, effectively improving the production quality and efficiency of the automated production line. Chinese Patent CN 112621390 A discloses a multi-process automated production control method and a multi-process automated production line. Through the application of control modules, ground rails, and robotic arms, it achieves automatic feeding / changing, processing, and unloading of multiple processing units at different processes on the same production line without human operation, as well as optimizing the processing cycle time. Chinese Patent CN 114803346 A discloses a control method, control device, and production line for an automated loading and unloading production line. The control device controls an automated guided vehicle (AGV) to transport steel plates to be processed to the cutting equipment. A gripping mechanism grips and sorts raw materials and finished products, improving the low efficiency problem caused by manual labor in the equipment manufacturing industry.

[0005] The aforementioned invention, through the design of the production line and the application of the control system, realizes material transportation based on transport tracks and AGVs, and material gripping and sorting based on robotic arms, thereby improving production efficiency and reducing the use of manpower. However, the aforementioned invention is mainly aimed at the field of machining, and the production line layout occupies a large area, which is not suitable for multi-chip component production lines arranged in clean rooms; at the same time, the aforementioned invention uses robotic arms to grip large-sized materials such as metal billets and steel, while for small-sized, low-strength multi-chip components with fragile components on the surface, rail transportation is more suitable.

In this embodiment, all products to be processed must be transported to the automatic dispensing machine 5 to complete the dispensing process. For products that have completed the dispensing process but not the placement process, which need to be processed by the first automatic placement machine 6, the transport process is similar to that of entering the automatic dispensing machine 5 and will not be described again.

[0181] For products that need to be processed by the second automatic placement machine 7 or the automatic curing oven 8, the handling method of the main track assembly 2 and the transfer machine 3 is similar to that of the automatic dispensing machine 5. The difference is that, since the orientation of the second automatic placement machine 7 and the automatic curing oven 8 is different from that of the automatic dispensing machine 5 and the first automatic placement machine 6, in order to ensure that the product enters the equipment in the same direction, the product needs to be rotated 180° on the branch track 9, which is connected to the loading track and has a 180° rotation capability, before being transported to the loading track of the second automatic placement machine 7 or the automatic curing oven 8.

[0182] Step S5: Product Assembly

[0183] The product to be processed enters the multi-chip component assembly automation equipment through the feeding track of the automatic dispensing machine 5; the QR code scanner located at the feeding track of the automatic dispensing machine 5 scans the QR code on the product to be processed, obtains the assembly program information required for the product to be processed from the control system, and calls the program; the program is run to assemble the product; the assembled product is transported to the unloading track of the automatic dispensing machine 5.

[0184] The product assembly process of the first automatic chip mounter 6, the second automatic chip mounter 7, and the automatic curing oven 8 is similar to that of the automatic dispensing machine 5, and will not be described in detail here.

[0185] Step S6: Product Completion Assessment

[0186] The QR code scanner at the equipment's unloading track scans products that have completed the "product assembly" step. The control system, based on the product process information, performs a completion check on the products that have completed the "product assembly" step, determining whether the product has completed all assembly processes. For completed products, the process proceeds to step S7, "completed product handling"; for incomplete products, steps S4, "product handling to be processed," and S5, "product assembly," are repeated to continue to the next assembly process until all assembly processes are completed.

[0187] Step S7: Handling of finished products

[0188] The control system schedules the production line based on the product completion information, transporting finished products to the unloading machine via branch tracks, transfer machines, and main tracks. In this embodiment, the final step is curing. Products that have completed curing in the automatic curing oven 8 are considered finished products. These finished products are transported to the unloading machine 10 via the straight branch track 4, transfer machine 3, and main track group 2. The transport process includes: the unloading track of the automatic curing oven 8 transports the finished product to the straight branch track 4; the straight branch track 4 transports the finished product to the transfer station of the transfer machine 3; the transfer machine 3 moves the transfer station and transports the finished product to the main track group 2 connected to the unloading machine 10; and the main track group 2 transports the product to the unloading machine 10.

[0189] Step S8: The unloading machine receives the finished products.

[0190] Finished products are transferred to the unloading machine 10 and temporarily stored until all products to be processed are assembled. The QR code scanner on the unloading machine 10 identifies the QR code information on the finished products and reports it to the control system.

[0191] Step S9: Product Delivery

[0192] The control system feeds back the finished product information of the unloading machine 10 to the workshop manufacturing execution system. After all products are assembled, the unloading machine 10 transports the products to the automated guided vehicle.
