[0036] The patch machine takes the chip on the blue film by the suction nozzle in use, the suction nozzle is installed on the patch machine through the swing arm, the patch machine rotates the swing arm, and then drives the suction nozzle to rotate, so as to rotate the chip to the next station.

[0037] The existing swing arm is concave at the bottom and is provided with a first through hole at the two sides, the structure makes the swing arm swing up and down when the gas enters the cavity from the first through hole and contacts the cavity wall.

[0038] The utility model provides a swing arm.

[0039] Please refer to Figure 1 , Figure 2In the embodiment of the utility model, the swing arm comprises a mounting seat 100, a fixed part 200 and a connecting part 300. The fixed part 200 is used for mounting a suction nozzle. One end of the connecting part 300 is connected to the mounting seat 100, and the other end is connected to the fixed part 200. It should be noted that the swing arm is mounted on the chip mounter through the mounting seat 100. The chip mounter is connected to the mounting seat 100. The chip mounter drives the mounting seat 100 to rotate, thereby driving the connecting part 300 and the fixed part 200 to rotate. Since the fixed part 200 rotates, the suction nozzle mounted on the fixed part 200 also rotates. Further, a hole-shaped air duct 400 is formed in the connecting part 300. The air duct 400 is horizontally arranged. The connecting part 300 has a first outer side and a second outer side arranged oppositely. One end of the air duct 400 penetrates through the first outer side, and the other end penetrates through the second outer side. Specifically, the hole-shaped air duct 400 is formed in the connecting part 300. On the one hand, the hole-shaped air duct 400 can make the connecting part 300 have a hollow structure, thereby making the structure of the connecting part 300 lightweight, and thus making the overall structure of the swing arm lightweight. On the other hand, under the action of the hole-shaped air duct 400, the area of the first outer side and the second outer side can be reduced. When the chip mounter drives the swing arm to rotate, the area of the first outer side and the second outer side in contact with the wind is reduced. That is, by arranging the hole-shaped air duct 400, the windward area of the swing arm can be reduced, and the wind resistance can be reduced. At the same time, the air duct 400 is horizontally arranged. One end of the air duct 400 penetrates through the first outer side, and the other end penetrates through the second outer side. When the chip mounter drives the swing arm to rotate, the wind flows along the horizontally arranged air duct 400. Further, the wind enters from one end of the air duct 400 and flows out from the other end. Since the air duct 400 is horizontally arranged, the force of the wind acting on the top wall and the bottom wall inside the air duct 400 is small when the wind flows. The influence of the wind force on the swing arm is reduced, thereby reducing the up-and-down swinging of the swing arm when it rotates, and thus solving the technical problem existing in the prior art. Further, the mounting seat 100, the fixed part 200 and the connecting part 300 are integrally formed. Integrally forming the mounting seat 100, the fixed part 200 and the connecting part 300 can further improve the overall strength of the swing arm, making the swing arm more stable during use, and thus making the suction nozzle more stable when it is driven to stop swinging by the chip mounter.

[0040] In one embodiment, reference is made to Figure 2The end of the connecting part 300 connected with the mounting base 100 is tapered towards the end connected with the fixing part 200. In this way, the weight of the connecting part 300 is further reduced, and the tapered connecting part 300 makes the structure far away from the mounting base 100 smaller when the mounting base 100 and the connecting part 300 swing together. At this time, the wind resistance of the structure far away from the mounting base 100 is also reduced. Specifically, the linear speed of the structure far away from the mounting base 100 is greater than that of the structure close to the mounting base 100. When the linear speed is large, the wind resistance of the connecting part 300 is reduced by reducing the windward area of the structure, thereby reducing the wind resistance of the swing arm when it swings.

[0041] In an embodiment, referring to Figure 2 , Figure 4 The end surface of the connecting part 300 is configured as a quadrilateral structure, which has a top surface 310, a bottom surface 320, a first side surface 330, and a second side surface 340. The first side surface 330 and the second side surface 340 are windward surfaces. The first outer side is configured as the first side surface 330, and the second outer side is configured as the second side surface 340. That is, the first outer side and the second outer side are windward surfaces. Specifically, when the swing arm rotates in one direction, one of the first outer side and the second outer side is a windward surface. When the swing arm swings in the other direction, the other one is a windward surface. Further, the quadrilateral structure can be a rectangle, a trapezoid, a parallelogram, or the like.

[0042] In an embodiment, referring to Figure 2, the first side surface 330 and the second side surface 340 are both inclined towards the middle position between the two, specifically, the top of the first side surface 330 and the second side surface 340 can be inclined towards the middle position between the two, or the bottom of the first side surface 330 and the second side surface 340 is inclined towards the middle position between the two, wherein the angle of inclination of the first side surface 330 and the second side surface 340 is not limited; at this time, the end surface of the connecting part 300 is in a trapezoidal structure in the process of tapering, under this structure, when the swing arm swings at high speed, because the first side surface 330 and the second side surface 340 are inclined, at this time the gas acting on the first side surface 330 or the second side surface 340 will flow upwards along the inclined surface, reducing the wind resistance when swinging, so that the swing arm can withstand higher speed, at the same time, the windward surface of the swing arm is provided with more hole-shaped structure air duct 400, under the action of the air duct 400, the area of the windward surface will be relatively small, at this time the resistance of the wind acting on the windward surface will be smaller. Further, in other embodiments, the top of the first side surface 330 can be inclined towards the middle position between the two, and the bottom of the second side surface 340 can be inclined towards the middle position between the two. Further, in this embodiment, the end surface of the connecting part 300 can be in a trapezoidal structure in the process of tapering, and the trapezoidal structure has relatively good structural strength compared to the parallelogram structure.

[0043] In an embodiment, referring to Figure 1 , Figure 2 , the connection between the top surface 310 and the fixed part 200 is inclined towards the bottom surface 320, which can make the structure of the connection between the connecting part 300 and the fixed part 200 smaller, so that the wind resistance at this place is smaller. At the same time, under the action of the quadrilateral structure of the end surface of the connecting part 300, the connection area between the connecting part 300 and the fixed part 200 can be larger, so that the connection stability between the two is better.

[0044] In an embodiment, referring to Figure 3 , the air duct 400 is provided in multiple, and the multiple air ducts 400 are arranged along the first direction. It can be understood that the two adjacent air ducts 400 can form a rib, which can make the structure of the connecting part 300 more stable, and as the number of air ducts 400 increases and the aperture increases, the thickness of the rib will be relatively reduced. However, the design is not limited to this, in some embodiments, the air duct 400 can be provided as one, wherein when the air duct 400 is provided as one, the size of the windward surface needs to be determined according to the size of the air duct 400, it can be understood that when the aperture of the air duct 400 is larger, the area of the windward surface is smaller; when the aperture of the air duct 400 is smaller, the area of the windward surface is larger.

[0045] Further, when the connecting portion 300 is tapered, the plurality of air ducts 400 are also tapered, and it can be understood that the hole diameters of the plurality of air ducts 400 are gradually reduced. Further, when the air duct 400 is provided as one, the connecting portion 300 is tapered, and at this time, the hole diameter of the air duct 400 close to the mounting seat 100 is greater than the hole diameter close to the fixing portion 200.

[0046] In an embodiment, referring to Figure 3 , the plurality of air ducts 400 are arranged in a row, so that the hole diameter of a single air duct 400 is relatively large, thereby reducing the area of the windward surface. However, the design is not limited thereto, and in other embodiments, when the plurality of air ducts 400 are arranged in the first direction, they can be arranged in two rows, three rows, etc.

[0047] In an embodiment, referring to Figure 1 , the connecting portion 300 is integrally formed with a groove 360 on the outside, and the groove 360 is used to install the air pipe, wherein the groove 360 is opened in the first direction, and under the action of the groove 360, the air pipe can be buried in the groove 360, and at this time, when the air pipe is swung together with the swing arm, the windward area of the air pipe can be reduced, and the air resistance can be reduced. Further, in actual use, in order to stably limit the air pipe in the groove 360, a strap can be provided on the swing arm, and the strap can pass through the air duct 400 during installation, so as to fix the air pipe on the swing arm. Since one end of the air duct 400 penetrates the first outer side of the swing arm, and the other end penetrates the second outer side of the swing arm, at this time, the strap can also pass through the swing arm more easily while passing through the air duct 400, which facilitates the installation of the strap and the fixing of the air pipe on the swing arm.

[0048] In an embodiment, referring to Figure 1 , the fixing portion 200 is formed with a fixing block 210, and the fixing block 210 is used to fix the air pipe. It can be understood that when the suction nozzle is replaced, the air pipe is separated from the suction nozzle, and at this time, the end of the suction nozzle is not limited and is easy to sag and sweep the material. In order to avoid this situation, when the suction nozzle is replaced, the end of the air pipe can be inserted into the fixing block 210, and the fixing block 210 fixes the air pipe, thereby avoiding the sagging of the air pipe and the sweeping of the material.

[0049] In an embodiment, referring to Figure 1The mounting hole 110 is formed on the mounting base 100, wherein the swing arm is mounted on the chip mounter through the mounting hole 110 on the mounting base 100, the avoiding groove 350 corresponding to the mounting hole 110 is formed on the outside of the connecting part 300, further, the structure of the mounting base 100 can be further reduced under the action of the avoiding groove 350, the structure of the mounting base 100 is more compact, the weight of the swing arm can be further reduced when the structure of the mounting base 100 is compact, the avoiding groove 350 is formed on the outside of the connecting part 300, the weight of the swing arm can be further reduced, and the swing arm is more lightweight. In an embodiment, the swing arm can be made of lightweight aluminum alloy material, under the action of the lightweight aluminum alloy material, the swing arm of the application can be lighter in weight and better in strength. In other embodiments, the swing arm can also be made of other materials, such as composite plastic, wherein the composite plastic can be fiber reinforced composite plastic.

[0050] In some embodiments, reference is made to Figure 1 The end of the fixing part 200 away from the connecting part is bent to form an elastic arm 220, the mounting position 230 is formed between the elastic arm 220 and the fixing part 200, and the mounting position 230 is used for mounting the suction nozzle, it should be noted that when the suction nozzle is mounted into the mounting position, the elastic arm 220 and the fixing part 200 are connected through screws or other fasteners, the elastic arm 220 and the fixing part 200 can be close to each other, so as to tighten the mounting position 230, and then clamp the suction nozzle, and the suction nozzle is limited on the fixing part 200.
