Description

Technical Field

[0001] This utility model belongs to the field of chip processing technology, specifically relating to an air blowing device for chip processing. Background Technology

[0002] In the chip mounting process, the chip is typically placed inside the lower mold, and solder is added to the bottom of the chip. Then, the upper and lower molds are closed and heated at high temperature for soldering. To prevent chip oxidation, an inert gas pump is used to pump inert gas into the upper and lower molds after the high-temperature soldering is completed. At the same time, the inert gas is used to cool the chip. After cooling is complete, the upper and lower molds are lowered, the molds are opened, and the processed chip is removed.

[0003] Currently, an air blowing pipe is typically installed inside the upper mold, and air holes can be opened on the air blowing pipe. The air inlet end of the air blowing pipe passes through the upper mold, and the air nozzle of the air pumping device is threadedly connected to the air inlet end of the air blowing pipe. Air is pumped into the upper and lower molds. After cooling is completed, the air nozzle is rotated to disconnect it from the air inlet end of the air blowing pipe. However, during the frequent connection and disconnection process, the threads will wear, causing air leakage at the connection between the air inlet end of the air blowing pipe and the air nozzle, which will affect the anti-oxidation effect of the chip.

[0004] Therefore, an air blowing device for chip processing is designed to solve the technical problem of air leakage caused by wear during frequent connection and disconnection of the threaded connection between the air nozzle and the air inlet end of the air blowing pipe in the prior art.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

[0006] This disclosure provides at least one air blowing device for chip processing.

[0007] In a first aspect, embodiments of this disclosure provide a blowing device for chip processing, comprising:

[0008] Upper mold and lower mold;

[0009] The upper and lower molds each have a semi-circular cavity with an opposing semi-circular opening on their outer walls on the same side, so as to form an insertion position after the two are fitted together; wherein

[0010] Both the upper and lower molds have arc-shaped grooves on their end faces where the insertion positions are located, and an arc-shaped snap-fit ​​groove is formed on one side of each arc-shaped groove; and

[0011] An air blowing mechanism includes an air tube, on which a rotating sleeve is fitted, and at least two snap-fit ​​elements are provided on the outer wall of the rotating sleeve; wherein...

[0012] The snap-fit ​​component is adapted to slide along the axis of the arc-shaped groove so that after the rotating sleeve follows the insertion of the air tube into the insertion position, it rotates and snaps into the arc-shaped snap-fit ​​groove.

[0013] In one optional embodiment, each of the arc-shaped snap-fit ​​grooves is arranged in an array along the rotation direction of the rotating sleeve on one side of the corresponding arc-shaped slide groove; wherein

[0014] The distance from the axis of the rotating sleeve to the apex of each arc-shaped groove is greater than the distance from the axis of the rotating sleeve to the apex of the corresponding arc-shaped snap-fit ​​groove.

[0015] In one optional embodiment, a plurality of connecting members are provided on the outer wall of the rotating sleeve; wherein

[0016] Each connector is connected to its corresponding snap-fit ​​component.

[0017] In one optional embodiment, a push sleeve is provided on the insertion end face of the trachea;

[0018] The push sleeve is slidably connected to several guide rods; and

[0019] Each of the guide rods has an abutment plate on its end face near the insertion position;

[0020] A sealing strip is provided between the abutment plate and the push sleeve; wherein

[0021] The trachea is adapted to be continuously inserted after the abutment plate abuts against the inner wall of the insertion position, so that the push sleeve moves toward the abutment plate to compress and deform the sealing strip.

[0022] In one optional embodiment, an exhaust pipe is provided inside the upper mold;

[0023] The air inlet end of the exhaust pipe is located within the insertion position; wherein

[0024] The air inlet is adapted to be connected to the air pipe after the air pipe is inserted into the connector.

[0026] The air tube is adapted to be continuously inserted after the abutment plate and the end face of the fixing member abut against each other, so as to deform the sealing strip.

[0027] The beneficial effects of this utility model are that, by setting up an air blowing mechanism, after the air tube is inserted into the insertion position, it is only necessary to rotate the rotating sleeve on the outer wall of the air tube, so that the rotating sleeve drives the snap-fit ​​piece set thereon to rotate and snap into the arc-shaped snap-fit ​​groove opened on the upper and lower molds to connect the air tube to the insertion position. After the processing is completed, it is only necessary to reverse the rotating sleeve to disengage the air tube from the insertion position.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0042] In this document, when it is mentioned that a first component is located on a second component, this can mean that the first component can be directly formed on the second component, or that a third component can be inserted between the first and second components. Furthermore, in the accompanying drawings, the thickness of the components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0043] In this document, when an element or layer is referred to as “located,” “joined to,” “connected to,” “attached to,” or “coupled to” another element or layer, it may be directly located, joined, connected, attached to, or coupled to the other element or layer, or there may be intermediate elements or layers present. Conversely, when an element is referred to as “directly on another element or layer,” “directly joined to,” “directly connected to,” “directly attached to,” or “directly coupled to” another element or layer, there may be no intermediate elements or layers present. Other terms used to describe relationships between elements should be interpreted in a similar manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the related listed items.

[0044] In this document, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as “at least one of…” modify the entire list of elements when following a list of elements, rather than individual elements in the list. For example, the expression “at least one of a, b, and c” should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0045] The terminology used herein is for the purpose of describing specific exemplary configurations only and is not intended to be limiting. As used herein, the singular articles “a,” “an,” and “the” may also be intended to include plural forms unless otherwise clearly stated herein. The terms “comprising,” “including,” and “having” are inclusive and thus specify the presence of features, steps, operations, elements, and / or components, but do not preclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof.

[0047] Research has revealed that existing systems typically include an air blowing pipe inside the upper mold, with air holes drilled in the pipe. The air inlet of the air blowing pipe passes through the upper mold, and the nozzle of the pumping device is threadedly connected to the air inlet of the air blowing pipe. Air is then pumped into the upper and lower molds. After cooling is complete, the nozzle is rotated to disconnect it from the air inlet of the air blowing pipe. However, during the frequent connection and disconnection process, the threads wear down, causing air leakage at the connection between the air inlet of the air blowing pipe and the nozzle, which in turn affects the cooling of the chip.

[0048] Based on the above research, this disclosure provides an air blowing device for chip processing. By providing an air blowing mechanism, after the air tube is inserted into the insertion position, it is only necessary to rotate the rotating sleeve on the outer wall of the air tube, so that the rotating sleeve drives the snap-fit ​​component on it to rotate and snap into the arc-shaped snap-fit ​​groove opened on the upper and lower molds to connect the air tube to the insertion position. After processing is completed, it is only necessary to reverse the rotating sleeve to disengage the air tube from the insertion position. Compared with the threaded connection method in the prior art, the wear is reduced and the phenomenon of air leakage caused by wear due to frequent disassembly will not occur.

[0049] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.

[0050] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0051] The following detailed description, with reference to the accompanying drawings, describes some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, before processing begins, the operator applies solder to the bottom of the chip 5 to be processed. Then, each chip 5 is placed inside the lower mold 2 one by one, and the upper mold 1 is placed on the upper surface of the lower mold 2, so that the air holes 12 opened on the exhaust pipe 11 inside the upper mold 1 correspond to the chips 5 placed in the lower mold 2. After the upper and lower molds are closed, the air pipe 40 is inserted into the insertion position 3, so that the air pipe 40 is connected to the air inlet end 11a of the exhaust pipe 11. The air pipe 40 pumps inert gas into the exhaust pipe 11, and then the air is discharged from each air hole to blow air onto the corresponding chip 5 to prevent oxidation. The gas in the upper and lower molds is finally discharged through the air guide pipe 10.

[0053] In some embodiments, such as Figure 2 and Figure 3 As shown, after the upper and lower molds are closed, the operator holds the air pipe 40 and inserts it into the insertion position 3. During the insertion process, the end face of the abutment plate 45 is made to abut against the end face of the fixing part 13. During the insertion process, the snap-fit ​​part 42 slides in the arc-shaped sliding groove 20. When the two opposite end faces abut against each other, the operator manually rotates the rotating sleeve 41, causing the connector 43 and snap-fit ​​part 42 on its outer wall to rotate synchronously, rotating the snap-fit ​​part 42 into the arc-shaped snap-fit ​​groove 21. The arc-shaped snap-fit ​​groove 21 is used to limit the snap-fit ​​part 42, thereby making the air pipe 40 and the air inlet end 11a of the exhaust pipe 11 securely connected. When disassembling, simply rotate the rotating sleeve 41 in the opposite direction to rotate the snap-fit ​​part 42 away from the arc-shaped snap-fit ​​groove 21.

[0054] In some embodiments, such as Figure 4As shown, when the abutment plate 45 is in contact with the end face of the fixing member 13, the operator holds the air tube 40 and continues to insert it in the insertion direction. At this time, the push sleeve 44 slides towards the abutment plate 45 along the guide rod 451. At this time, the sealing strip 46 between the abutment plate 45 and the push sleeve 44 is squeezed and deformed, thereby filling the gap between the upper and lower mold insertion position 3 and the push sleeve 44, and avoiding air leakage during the pumping process.

[0055] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0056] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, 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, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.

[0057] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0058] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.

[0059] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
