Description

Technical Field

[0001] This invention relates to the field of electronic component manufacturing equipment technology, and in particular to an automatic rotary reflow oven and a packaging product production line. Background Technology

[0002] In the electronics manufacturing industry, QFN (Quad Flat No-lead Package) and DFN (Dual Flat No-lead Package) are mainstream surface-mount semiconductor packaging forms. They are widely used in various precision electronic products such as smartphones, IoT devices, and automotive electronics due to their advantages of small size, excellent heat dissipation, and stable electrical performance. With the continuous increase in downstream industries' requirements for the integration and miniaturization of electronic products, the market demand for QFN & DFN packaged products is increasing year by year, and the corresponding requirements for manufacturing efficiency and compatibility are becoming increasingly stringent.

[0003] Currently, the transfer of QFN & DFN packaged products to the welding tray before and after welding in the ETC nitrogen vacuum furnace still largely relies on manual labor. Specifically, before welding, operators must manually place each individual QFN & DFN product into the corresponding station on the welding tray, and after welding, manually remove the product from the tray. This operation mode has significant drawbacks: on the one hand, manual operation is inefficient and difficult to match the cycle time requirements of large-scale mass production lines, and prolonged repetitive labor can easily lead to operator fatigue, resulting in misplacement, omission, or damage during removal, affecting the welding yield and appearance quality of the products; on the other hand, the consistency of manual operation is poor, and the positioning accuracy of the product in the tray cannot be guaranteed, indirectly affecting the stability of subsequent welding processes.

[0004] Furthermore, in some existing production scenarios, QFN & DFN products are carried and transported in batches using carriers. However, there is currently a lack of automated transport equipment that is compatible with both the products themselves and the corresponding carriers. Traditional equipment can only accommodate bare products of a single size or carriers of specific specifications. When faced with QFN & DFN products with different pin counts and package sizes, or when changing carrier types, the equipment structure must be readjusted or special tooling must be replaced. This not only increases production changeover time and equipment investment costs but also reduces the production line's flexible production capacity, making it difficult to meet the market demand for multi-variety, small-batch orders.

[0005] Therefore, there is an urgent need to propose an automatic rotary reflow machine and a packaging product production line to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to solve or at least alleviate some or all of the aforementioned problems. Therefore, the purpose of this invention is to provide an automatic rotary ladle machine and a packaging product production line to achieve automatic transfer of packaged products and corresponding carriers before and after the processing furnace.

Next, the transfer component drives the product suction component to transfer the products from the welding pallets to the product flow line, or drives the carrier clamping component to transfer the carriers carrying the products from the welding pallets to the product flow line. The product flow line then transfers the products or carriers to the downstream flow line. Then, the steering drive component drives the pallet carrier to the first station.

[0050] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0051] In this invention, the terms "comprising," "including," "having," or any other variations thereof are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0052] In this invention, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A alone, A and B simultaneously, and B alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following related objects have an "and / or" relationship.

[0053] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," "combined," "coupled," and "installed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a direct connection or an indirect connection via an intermediate medium; or the internal communication of two components or the interaction between two components. As examples, a direct connection refers to two parts or components being connected together without the need for an intermediate medium, while an indirect connection refers to two parts or components each being connected to at least one intermediate medium, with the connection achieved through the intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Furthermore, "connected" and "coupled" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0054] In this invention, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the value and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0055] In this invention, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0056] In this invention, the terms "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientations or positional relationships shown in the accompanying drawings. They are used solely for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, in the context, it should be understood that when an element is mentioned as being "upper" or "lower" than another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as "upper side," "lower side," "left side," "right side," "front side," and "rear side" not only represent positive orientation but can also be understood as lateral orientation. For example, "above," "on top of," "upper side of," and "above" the first feature "above" or "on the second feature" includes the first feature being directly above, to the upper left, to the upper right, to the upper front, and to the upper rear of the second feature, or simply indicating that the first feature is at a higher horizontal level than the second feature. The terms "below," "under," "below," and "below" for "first feature" and "second feature" include situations where the first feature is directly below, to the lower left, to the lower right, in front of, or behind the second feature, or simply indicate that the first feature is at a lower horizontal level than the second feature. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0057] like Figures 1-9 As shown, this embodiment provides an automatic rotary table for automatically transferring packaged products 100 and corresponding carriers 200 into and out of the processing furnace 300. The processing furnace 300 has an automatic rotary table at both its inlet and outlet. The rotary table at the inlet of the processing furnace 300 is a front-of-furnace rotary table 10, configured to transfer the product 100 or the carrier 200 carrying the product 100 to the transport line of the processing furnace 300. The rotary table at the outlet of the processing furnace 300 is a rear-of-furnace rotary table 20, configured to remove the product 100 or the carrier 200 carrying the product 100 from the transport line of the processing furnace 300.

[0058] The automatic rotary table for furnace transfer includes a welding pallet 1, a frame 2, a product transfer mechanism 3, a product transfer pallet flow line 4, a steering mechanism 6, and a handling mechanism 7. The welding pallet 1 is used to carry products 100 or carriers 200. The product transfer mechanism 3 is mounted on the frame 2 and includes a product flow line 31 for receiving and transporting products 100 or carriers 200, wherein the carrier 200 carries products 100. The product transfer pallet flow line 4 is mounted on the frame 2 and is used to receive and transport the welding pallet 1. The pallet docking flow line 5 is mounted on the frame 2 and docks with the transport flow line of the processing furnace 300. The steering mechanism 6 is mounted on the frame 2 and includes a mounting base 61, a steering drive assembly, and a pallet support platform 64. The pallet support platform 64 is used to carry the welding pallet 1 and has a first station that docks with the product transfer pallet flow line 4, as well as a docking station with the product transfer pallet flow line 4. The second station of the pallet docking flow line 5 has a steering drive assembly mounted on the mounting base 61. The output end of the steering drive assembly is connected to the pallet carrier platform 64 to transfer the pallet carrier platform 64 between the first station and the second station. The handling mechanism 7 is mounted on the frame 2 and includes a transfer assembly and a product picking assembly 73, a carrier clamping assembly 74, and a pallet clamping assembly 75 located at the output end of the transfer assembly. The product picking assembly 73 is used to pick up the product 100, the carrier clamping assembly 74 is used to clamp the carrier 200, and the pallet clamping assembly 75 is used to clamp the welding pallet 1. The transfer assembly is configured to drive the product 100 or the carrier 200 to transfer between the connecting product flow line mechanism 3 and the welding pallet 1 located on the pallet carrier platform 64, and to drive the welding pallet 1 to transfer between the connecting pallet flow line 4 and the pallet carrier platform 64.

[0059] At the entrance of the processing furnace 300, the furnace-front rotary table 10 first receives and transports the welding pallet 1 from the upstream flow line via the connecting pallet flow line 4, and receives and transports the product 100 or the carrier 200 carrying the product 100 via the upstream flow line 31. Next, the transfer component drives the pallet clamping component 75 to transfer the welding pallet 1 on the connecting pallet flow line 4 to the pallet support platform 64 located at the first station. Then, the transfer component drives the product suction component 73 to transfer the product 100 on the product flow line 31 to the welding pallet 1 located on the pallet support platform 64, or drives the carrier clamping component 74 to transfer the carrier 200 on the product flow line 31 to the welding pallet 1 located on the pallet support platform 64. Finally, the steering drive component drives the pallet support platform 64 to the second station, so that the welding pallet 1 enters the pallet docking flow line 5, and the pallet docking flow line 5 transports the welding pallet 1 to the transport flow line of the processing furnace 300.

[0060] At the outlet of the processing furnace 300, the furnace turntable 20 first receives the welding pallet 1 from the transport flow line of the processing furnace 300 via the pallet docking flow line 5. The pallet carrier 64 at the second station can receive the welding pallet 1 on the pallet docking flow line 5. Then, the transfer component drives the product suction component 73 to transfer the product 100 on the welding pallet 1 to the product flow line 31, or drives the carrier clamping component 74 to transfer the carrier 200 carrying the product 100 on the welding pallet 1 to the product flow line 31. The product flow line 31 then transfers the product 100 or the carrier 200 to the downstream flow line. Then, the steering drive component drives the pallet carrier 64 to the first station. Finally, the transport mechanism 7 drives the pallet clamping component 75 via the transfer component to transfer the welding pallet 1 on the pallet carrier 64 at the first station to the connecting pallet flow line 4. The connecting pallet flow line 4 then transfers the welding pallet 1 to the downstream flow line.

[0061] By adopting the aforementioned automatic rotary table machine, the packaged product 100 and its corresponding carrier 200 can be automatically transferred in and out of the processing furnace 300, thereby reducing manual intervention and avoiding problems such as product 100 damage and positioning deviation caused by human fatigue or improper operation. This improves the stability and reliability of the production process, increases the welding yield and appearance quality of product 100, shortens the transfer time of product 100 before and after welding, improves production efficiency, and reduces manufacturing costs. Furthermore, for the bare packaged product 100, the product suction component 73 suctions the product 100 by adsorption, which reduces the risk of product damage and improves the appearance quality of the product. On the other hand, the adsorption method does not require precise adaptation to the size of the product 100 and can be compatible with bare packaged products 100 within a certain size range. For the product 100 with the carrier 200, the carrier clamping component 74 clamps the carrier 100, which can realize the transfer of the product 100 with the carrier 200. Thus, the automatic reflow turntable can be compatible with bare packaged products 100 and corresponding carriers 200 within a certain size range. It can realize rapid line changeover production of multiple varieties and sizes of products 100 without frequent tooling changes or equipment structure adjustments, thereby improving the flexible production capacity of the production line.

[0062] like Figure 3 and Figure 5As shown, in some optional embodiments, the connecting pallet flow line 4 extends along a first direction, and the pallet docking flow line 5 extends along a second direction to adapt to the layout of the first pallet connecting line 400 and the transport flow line of the processing furnace 300. At the same time, it can improve the structural compactness and layout rationality of the automatic turntable machine for furnace transfer, and improve the flow efficiency of product 100 or carrier 200 and welding pallet 1. The steering drive assembly includes a first lifting drive 62 and a rotating drive 63. The output end of the rotating drive 63 is connected to the pallet support platform 64 for driving the pallet support platform 64 to rotate around the vertical direction. The first lifting drive 62 is mounted on the mounting base 61, and the output end of the first lifting drive 62 is connected to the rotating drive 63 for driving the pallet support platform 64 to rise and fall along the vertical direction. The first direction, the second direction and the vertical direction are perpendicular to each other.

[0063] The first lifting drive 62 drives the welding pallet 1 to rise vertically to avoid the connecting pallet flow line 4 and the pallet docking flow line 5, providing space for the rotation of the pallet support platform 64. The rotation drive 63 drives the pallet support platform 64 to rotate from the direction of docking with the connecting pallet flow line 4 to the direction of docking with the pallet docking flow line 5. The welding pallet 1 protrudes from the edges of the pallet support platform 64 on both sides. The first lifting drive 62 drives the pallet support platform 64 to descend vertically, allowing the two sides of the welding pallet 1 to automatically overlap onto the pallet docking flow line 5 and be conveyed by it. The first lifting drive 62 drives the pallet support platform 64 to rise vertically, transferring the welding pallet 1 from the pallet docking flow line 5 onto the pallet support platform 64, thus achieving automatic conveying of the welding pallet 1.

[0064] In some optional embodiments, the product flow mechanism 3 further includes a push-pull assembly, which includes a support plate 34, a slide rail 35, and a slider. The support plate 34 supports the product flow 31, the slide rail 35 is connected to the frame 2 and extends along the width direction of the product flow 31, and the slider is connected to the support plate 34, with the slide rail 35 and the slider slidingly engaged. By pulling the support plate 34, the product flow 31 can be moved to a position closer to the operator, facilitating the adjustment of the width of the product flow 31. Furthermore, the support plate 34 is also provided with a handle for the operator to grip.

[0065] It is easy to understand that the width of the carrier 200 is greater than the width of the product 100. Therefore, the width of the product streamline 31 is adjustable to accommodate the size difference between the product 100 and the carrier 200.

[0066] Specifically, such as Figure 3 and Figure 4As shown, the product flow line 31 includes at least two conveying components 311 arranged side-by-side along its width direction. These at least two conveying components 311 jointly support and transport the product 100 or the carrier 200. At least one conveying component 311 is adjustablely connected to the support plate 34 in the width direction to adjust the width of the product flow line 31. The width direction of the product flow line 31 is a horizontal direction perpendicular to its conveying direction. By adjusting the position of at least one conveying component 311 in the width direction, the width of the product flow line 31 can be precisely adapted to the width of the product 100 or the carrier 200, which helps improve the stability and reliability of the automatic rotary kiln machine in conveying the product 100 or the carrier 200, and enhances the flexible production capacity of the production line.

[0067] More specifically, the conveying assembly 311 includes a mounting base, a drive component, a conveyor belt, a drive wheel, and a transmission wheel. The drive wheel and transmission wheel are spaced apart on the mounting base along the conveying direction of the product flow line 31. The conveyor belt is tensioned on the drive wheel and transmission wheel. The drive component is mounted on the mounting base, and its output end is connected to the drive wheel to drive the conveyor belt. The mounting base is adjustablely connected to the support plate 34 in the width direction of the product flow line 31. For example, the support plate 34 has multiple mounting interfaces spaced apart along the width direction of the product flow line 31, and the mounting base is selectively connected to any of these mounting interfaces.

[0068] In some optional embodiments, the connecting product flow line mechanism 3 further includes a positioning component, which includes at least two first positioning elements 32 and at least two second positioning elements 33. The at least two first positioning elements 32 are spaced apart along the conveying direction of the product flow line 31 and are used to position the product 100 or carrier 200 from both ends of the conveying direction. The at least two second positioning elements 33 are spaced apart along the width direction of the product flow line 31 and are used to position the product 100 or carrier 200 from the width direction. This positions the product 100 or carrier 200 on the product flow line 31 so that the product pick-up component 73 or carrier clamping component 74 can clamp it. This ensures the positioning accuracy of the packaged product 100 or carrier 200 when it is transferred into the welding tray 1, avoids the welding process effect caused by placement offset, reduces the generation of defective products, and further improves the welding yield and appearance quality of the product 100.

[0069] like Figure 3 and Figure 6 As shown, in some optional embodiments, the transfer assembly includes a three-axis drive module 71 configured to drive the product pick-up assembly 73, the carrier clamping assembly 74, and the pallet clamping assembly 75 to move along a first direction, a second direction, and a vertical direction.

[0070] In some optional embodiments, the transfer assembly further includes a second lifting drive 72, which is disposed at the output end of the three-axis drive module 71 and is driveably connected to the product suction assembly 73 for driving the product suction assembly 73 to move vertically; and / or, the second lifting drive 72 is driveably connected to the carrier clamping assembly 74 for driving the carrier clamping assembly 74 to move vertically. By driving the product suction assembly 73 and / or the carrier clamping assembly 74 to move vertically through the second lifting drive assembly, the vertical degree of freedom of the two is separated from that of the pallet clamping assembly 75, which can accommodate the height difference between the product 100 or carrier 200 and the welding pallet 1 in the vertical direction, and can realize the precise picking, placing and transferring of the product 100 or carrier 200. This not only effectively avoids problems such as pick-and-place misalignment and product collisions caused by height mismatch, improving the stability and accuracy of workpiece transfer, but also expands the equipment's adaptability to different specifications of products 100, carriers 200, and welding trays 1, reducing the equipment's limitations on workpiece size. Simultaneously, the independent second lifting drive 72 can precisely adjust the lifting stroke and speed according to actual working conditions, further optimizing the equipment's motion coordination and improving the overall operating efficiency and processing yield of the packaging product production line.

[0071] like Figure 6 and Figure 7 As shown, in some optional embodiments, the product suction assembly 73 includes a first mounting frame 731, at least two mounting members 732, and a plurality of suction cups 733 disposed on the mounting members 732. The suction cups 733 are connected to a negative pressure source via an air passage for suctioning the product 100. The mounting frame 731 is disposed at the output end of the second lifting drive member 72. At least one mounting member 732 is adjustablely connected to the mounting frame 731 along the width direction of the product flow line 31. By adjusting the position of the mounting member 732 along the width direction of the product flow line 31, the suction width of the product suction assembly 73 can be adjusted, thereby adapting to products 100 or carriers 200 of different sizes.

[0072] For example, the mounting component 732 has an adjustment groove extending along the width direction of the product flow line 31. The locking bolt passes through the adjustment groove and locks to the mounting bracket 731. By loosening the locking bolt, the adsorption width of the product suction component 73 can be easily adjusted.

[0073] like Figure 8 As shown, the vehicle clamping assembly 74 includes a first clamping drive 741 and at least two first grippers 742. The first clamping drive 741 is disposed at the output end of the second lifting drive 72. The output end of the first clamping drive 741 is connected to the first grippers 742 for driving the first grippers 742 to close or open in order to grab or release the vehicle 200.

[0074] like Figure 9 As shown, the pallet clamping assembly 75 includes a second clamping drive 751 and at least two second grippers 752. The second clamping drive 751 is disposed at the output end of the three-axis drive module 71. The output end of the second clamping drive 751 is connected to the second grippers 752 for driving the second grippers 752 to close or open in order to grasp or release the welding pallet 1.

[0075] In addition, such as Figures 1-9 As shown, this embodiment also provides a packaging product production line, including a processing furnace 300 and at least two automatic rotary tables for reflow ovens according to any of the above embodiments. The processing furnace 300 has automatic rotary tables at its inlet and outlet ends. The rotary table at the inlet end of the processing furnace 300 is a front-of-furnace rotary table 10, configured to convey the product 100 or a carrier 200 carrying the product 100 to the transport line of the processing furnace 300. The rotary table at the outlet end of the processing furnace 300 is a rear-of-furnace rotary table 20, configured to remove the product 100 or the carrier 200 carrying the product 100 from the transport line of the processing furnace 300. By employing the above-mentioned automatic rotary tables, the automatic entry and exit of the packaged product 100 and its corresponding carrier 200 before and after the processing furnace 300 is achieved.

[0076] In some optional embodiments, the packaging product production line further includes a first pallet connecting line 400, a second pallet connecting line 500, a first product connecting line, and a second product connecting line. The first pallet connecting line 400 connects to the connecting pallet flow line 4 of the furnace front rotary table 10, the first product connecting line connects to the product flow line 31 of the furnace front rotary table 10, and the second pallet connecting line 500 connects to the connecting pallet flow line 4 of the furnace rear rotary table 20, and the second product connecting line connects to the product flow line 31 of the furnace rear rotary table 20. By setting the furnace front rotary table 10 and the furnace rear rotary table 20 before and after the processing furnace 300 respectively, a fully automated conveying link for the packaging product 100 from furnace front loading to furnace rear unloading is constructed, completely replacing the manual transfer link, avoiding the efficiency bottleneck, product 100 bumping and contamination risks caused by manual operation, and significantly improving the continuity and stability of the production line operation. Meanwhile, the precise connection between each connecting line and the turntable ensures the smooth flow of welding tray 1 and product 100 or carrier 200 between processes, reducing transfer waiting time and optimizing production cycle time. Furthermore, the aforementioned automated connecting structure is compatible with a certain range of bare packaged products 100 and corresponding carriers 200, enhancing the versatility and flexible production capabilities of the packaging product production line. It reduces the adjustment costs for switching between multiple product types 100, helping to improve the overall processing efficiency and product yield of the packaging product production line, providing a reliable guarantee for large-scale mass production.
