[0002] In the related art, the pin transmission mechanism of the automatic pin-loading equipment for PCB drilling includes a spring tube and a conventional joint, wherein the pin has weak magnetism. During the pin transmission process, there is magnetic adsorption between the pins, which easily causes the pins to stick together during the transmission process, making it easy for the pin transmission mechanism to break (pin) and cause a production failure alarm and shutdown.

[0003] In addition, the magnetic field or magnetic force is inconsistent when different numbers of pins are connected, and the deformation that occurs during the movement of the nail delivery pipe makes the contact area between the nail delivery pipe and the pins inconsistent, which leads to inconsistent resistance on the pins. When the combined force of the magnetic force and the pipe wall resistance is greater than the pin's own gravity, the pin will be stuck in the nail delivery pipe. Utility Model Content

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0032] See also Figure 1 and Figure 2 As shown, an embodiment of the present application discloses a pin separation device, which can effectively solve the problem that the pins cannot be separated due to magnetic attraction by utilizing airflow to push the pins forward.

[0033] See also Figure 1 and Figure 2 As shown, the pin separation device includes a connecting structure 100 and a blowing assembly. The connecting structure 100 is installed above the loading trough. The connecting structure 100 is used to transport the pins to the loading trough. The blowing assembly is used to blow air into the conveying channel 110 in the connecting structure 100, thereby using the airflow to drive the pins forward.

[0034] Specifically, the connection structure 100 includes a connection body 121 and a guide structure 122. The connection body 121 has a conveying channel 110 inside. The side wall of the connection body 121 is provided with an air inlet hole 124, and the air inlet hole 124 is connected to the conveying channel 110. The guide structure 122 is connected to the connection body 121 and is located in the conveying channel 110. The guide structure 122 is used to guide the airflow flowing in from the air inlet hole 124 to the outlet end of the conveying channel 110; the blowing component has an air inlet channel 211, and the air inlet channel 211 is connected to the air inlet hole 124. The blowing component is used to blow air into the conveying channel 110.

[0035] Among them, the projection of the guide structure 122 along the axial direction of the air inlet hole 124 is at least partially located inside the air inlet hole 124, so that the airflow flowing into the conveying channel 110 from the air inlet hole 124 cannot directly rush toward the pin along the axial direction of the air inlet hole 124, which is beneficial to reduce the jamming phenomenon during the pin conveying process.

[0036] In the embodiment of the present application, the air inlet channel 211 of the blowing assembly is connected to the air inlet hole 124, and the air inlet hole 124 is connected to the conveying channel 110 for conveying pins. In this way, by using the blowing assembly to blow air into the conveying channel 110 through the air inlet channel 211, the air flow can be used to drive the pins forward, thereby effectively solving the problem that the pins cannot be separated due to magnetic attraction. At the same time, the setting of the guide structure 122 can reduce the air flow directly blowing the pins in the conveying channel 110, which helps to reduce the jamming phenomenon of the pins in the conveying channel 110.

[0037] It should be noted that the pin may also be other parts with weak magnetism.

[0038] It is worth understanding that when the guide structure 122 is not provided, the gas flowing into the delivery channel 110 from the air inlet 124 will directly act vertically on the pin, and at this time, the pin will be slightly stuck. In the embodiment of the present application, by providing the guide structure 122, the flow direction of the airflow can be changed, thereby helping to reduce the phenomenon of pin stuck.

[0039] In the embodiment of the present application, the delivery channel 110 includes an inlet end 111 and an outlet end 112 , and the inlet end 111 and the outlet end 112 are respectively arranged on two oppositely arranged end surfaces of the connection body 121 .

[0040] See also Figure 3 and Figure 4 In one embodiment of the present application, one end of the guide structure 122 is connected to the edge of the air inlet 124 away from the outlet end, and the other end of the guide structure 122 extends toward the outlet end. Specifically, there is a gap between the guide structure 122 and the edge of the air inlet 124 close to the outlet end, and the gap can allow airflow to flow through.

[0041] In actual operation, after the gas flows from the air inlet channel 211 of the blowing assembly to the air inlet hole 124, it can flow into the conveying channel 110 through the gap between the guide structure 122 and the edge of the air inlet hole 124. In this process, the gas can abut against the pin located in the conveying channel 110, thereby driving the pin to flow toward and away from the outlet end, so that the pin is separated from the outlet end. Among them, the guide structure 122 is at least partially located on the extended side of the air inlet hole 124, reducing the situation where the gas directly impacts the pin along the axial direction of the air inlet hole 124. In this way, the situation where the pin is stuck in the conveying channel 110 due to the gas pushing the pin laterally can be reduced.

[0042] Further, see Figure 4, a cavity is enclosed between the outer wall of the guide structure 122 and the connecting body 121, and the cavity is connected to the air inlet 124. When the gas enters the delivery channel 110 through the air inlet 124, part of the gas will first flow to the aforementioned cavity and then flow toward the outlet end. In other words, in the process of the blowing component blowing air into the delivery channel 110, the aforementioned cavity will be filled with gas, that is, there will be airflow on the outer wall of the guide structure 122. Since there is gas at various positions on the circumference of the guide structure 122, it can contact various positions on the circumference of the pin, reducing the uneven force on the pin, thereby effectively reducing the jamming phenomenon caused by the pin being blown by the gas; and after the gas fills the cavity, it flows toward the outlet end as a whole, which can further push the pin to move toward the outlet end.

[0043] In some embodiments of the present application, the flow-guiding structure 122 is an annular structure. Specifically, a cavity is provided at the position of the outer wall surface of the flow-guiding structure 122 corresponding to the connection body 121, that is, there is a certain interval between the outer wall of the flow-guiding structure 122 and the connection body 121. In this way, after the gas abuts against the outer wall of the flow-guiding structure 122, part of the gas can flow along the cavity between the outer wall of the flow-guiding structure 122 and the connection body 121, so that the outer wall of the flow-guiding structure 122 is filled with gas, and the gas between the outer walls of the flow-guiding structure 122 flows toward the outlet end due to the action of air pressure, pushing the pin to move toward one side of the outlet end. Since the flow-guiding structure 122 has gas at various positions on the circumference, it can contact various positions on the circumference of the pin, reducing the uneven force on the pin, thereby effectively reducing the jamming phenomenon caused by the pin being blown by gas.

[0044] In some embodiments of the present application, see Figure 3 and Figure 4 The end of the guide structure 122 near the outlet end is provided with a guide slope 1221, and the guide slope 1221 is arranged to be inclined toward the outlet end. In this way, the gas can flow into the delivery channel 110 along the guide slope 1221. In this process, the guide slope 1221 can be used to change the flow direction of the gas, that is, the flow direction of the gas is changed from flowing along the axial direction of the air inlet 124 to flowing tangentially along the guide slope 1221. In this way, the generation of turbulence can be reduced, and appropriate gas can flow directly toward the outlet end of the delivery channel 110, which is conducive to improving the separation effect of the pins.

[0045] In the above embodiment, the guide slope 1221 can make the airflow contact the pins obliquely, which can not only separate the pins that are adhered to each other with the help of the airflow, but also use the airflow to push the pins to move toward the outlet end.

[0046] In some possible implementations, see Figure 4, the angle between the guide slope 1221 and the extension direction of the conveying channel 110 is set to 40°~50°. Among them, the extension direction of the conveying channel is the X direction in the figure. Specifically, the conveying channel 110 extends along the X direction, and the angle between the guide slope 1221 and the extension direction of the conveying channel 110 is 40°~50°, which can reduce the angle between the airflow direction and the pin movement direction, and help to increase the force of the gas on the pin in the extension direction of the conveying channel 110, thereby ensuring the pin separation effect. At the same time, the force on the pin along the radial direction of the conveying channel 110 can be reduced, thereby reducing the situation where the pin is stuck in the conveying channel 110.

[0047] In practical applications, the angle between the guide slope 1221 and the conveying channel 110 can be set to 40°, 42°, 43°, 44°, 45°, ... or 50° as needed.

[0048] In some embodiments of the present application, see Figure 1 and Figure 2 The blowing assembly includes a pressure regulating valve 210, which has an air inlet channel 211 connected to the air inlet hole 124. In this way, the gas in the air inlet channel 211 can flow into the delivery channel 110 through the air inlet hole 124 and push the pin in the delivery channel 110 to move toward the outlet end.

[0049] In one embodiment of the present application, the pressure regulating valve 210 is provided with a connecting section 212 , and the connecting section 212 is connected to the air inlet 124 .

[0050] Furthermore, the air inlet hole 124 is provided with an internal thread, the connecting section 212 is provided with an external thread matching the internal thread of the air inlet hole 124 , and the connecting section 212 is threadedly connected to the air inlet hole 124 .

[0051] See also Figure 2 The air inlet channel 211 includes a first channel 2111 and a second channel 2112, wherein the first channel 2111 is connected to the second channel 2112 and the air inlet hole 124, wherein the extension direction of the first channel 2111 is arranged to intersect with the delivery channel 110. In other words, the extension direction of the first channel 2111 is arranged at a certain angle to the extension direction of the delivery channel 110, which helps to evenly distribute the gas on the outer wall of the flow guide structure 122 and then flow toward the outlet end of the delivery channel 110, thereby reducing the jamming phenomenon caused by uneven force on different positions of the pin.

[0052] In some embodiments of the present application, see Figure 3 and Figure 4The connection body 121 includes a first connection member 1211 and a second connection member 1212. The first connection member 1211 is provided with a first connection portion, the second connection member 1212 is provided with a second connection portion that cooperates with the first connection portion, the flow guide structure 122 is connected to the first connection member 1211, and the air inlet 124 is provided at the second connection member 1212. In other words, the connection body 121 is assembled by the first connection member 1211 and the second connection member 1212.

[0053] Please continue to see Figure 4 As shown, one end of the flow guiding structure 122 is connected to one end of the first connecting member 1211 close to the second connecting member 1212, and the other end of the flow guiding structure 122 extends toward the outlet end of the second connecting member 1212. That is, when the first connecting member 1211 and the second connecting member 1212 are not assembled, the outer wall of the flow guiding structure 122 is exposed, so that the flow guiding structure 122 can be easily processed and the processing and manufacturing difficulty of the connection structure 100 can be reduced.

[0054] In the above embodiment, one end of the second connecting member 1212 is fixedly connected to the first connecting member 1211, and the length of the end of the second connecting member 1212 connected to the first connecting member 1211 is greater than the length matched with the first connecting member 1211. At the same time, the outer diameter of the guide structure 122 is smaller than the outer diameter of the first connecting part. Therefore, a cavity can be enclosed between the interior of the second connecting part and the outer wall of the guide structure 122, and the cavity is connected to the air inlet 124 and the outlet end.

[0055] In this embodiment, please continue to refer to Figure 4 The first connection part is provided with an external thread, the second connection part is provided with an internal thread, and the first connection part and the second connection part are threadedly connected.

[0056] In this embodiment, see Figure 4 The flow guiding structure 122 is an annular structure, and the outer wall at the end of the flow guiding structure 122 is provided with a flow guiding slope 1221 for guiding the gas flow. The annular flow guiding structure 122 is arranged concentrically with the delivery channel 110. In some embodiments of the present application, see Figure 4 The second connecting member 1212 is provided with a guide surface 12121 at the end of the guide structure corresponding to the guide structure, and a gap 123 is provided between the guide surface 12121 and the guide structure 122. The gap 123 allows gas to flow into the delivery channel 110.

[0057] In one embodiment of the present application, the connection structure 100 may specifically be a threaded interface, and the threaded interface has a delivery channel 110 for delivering pins.

[0058] Compared with separating the pins by mechanical vibration, in the embodiment of the present application, a blowing assembly is provided to blow air into the conveying channel 110 to separate the stuck pins, which can effectively simplify the structural design of the pin separation device and reduce the complexity of operation.

[0059] On the other hand, an embodiment of the present application discloses a pin conveying device, including the pin separation device as described above, which has the effective technical effects of the aforementioned pin separation device and will not be repeated here.

[0060] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
