Abstract
Description
Technical Field
[0001] This application relates to an automated transfer device for tiny parts. Background Technology
[0002] Cooling fans are widely used in various modern instruments and equipment such as computers, communication products, optoelectronic products, and consumer electronics to ensure the heat dissipation of core components inside the equipment and avoid problems such as equipment malfunction due to overheating.
[0003] Cooling fans in electronic products are very small. In the assembly process of cooling fans, the conveyor assembly pressure ring is a very important part. If the pressure ring is not fixed during the conveyor assembly process, it is difficult to assemble the pressure ring into the inside of the cooling fan. When the pressure ring is not installed in place, it will cause the shaft to contact the inner surface of the bearing or detach from the inside of the shaft tube when rotating, resulting in problems such as shaft wear or fan wheel rotation not being smooth.
[0004] In traditional processes, the pressure ring is usually installed manually. A pneumatic suction needle is typically used to pick it up and move it to drop it for installation. However, because the pressure ring is very light, it may not be able to fall off the pneumatic suction needle to the installation position. Therefore, it is necessary to manually shake the pneumatic suction needle to force the pressure ring to fall off. However, this operation increases the risk of improper assembly of the pressure ring, and is also labor-intensive and costly.
[0005] Therefore, a new device needs to be designed to solve the above-mentioned technical problems. Summary of the Invention
[0006] The purpose of this application is to provide an automatic transfer device for micro parts, which transports micro parts through a conveying mechanism to a suction and release mechanism, whereby the suction and release mechanism places the micro parts in a cooling fan, making it difficult for the micro parts to fall off or detach during the transport process.

A receiving cavity is formed inside the telescopic unit, and the receiving cavity extends upward through the top surface to form a first opening and a second opening. The drive structure drives the telescopic unit to reciprocate between a first position and a second position along a first direction on the first fixed unit.
[0010] A positioning unit is movably disposed inside the receiving cavity and has a first limiting part and a second limiting part; at least one elastic element is located inside the receiving cavity, the elastic element exerts an upward thrust on the positioning unit, causing the first limiting part to protrude upward through the first opening to above the top surface, and at the same time causing the second limiting part to protrude upward through the second opening; a pressing part covers at least a portion of the top surface of the first fixing unit.
[0011] When the telescopic unit moves from the first position to the second position, the first limiting part is limited by the pressing part and descends, and the end of the first limiting part abuts against the lower surface of the pressing part, thereby maintaining the end edge of the second limiting part not higher than the lower surface of the pressing part.
[0012] Furthermore, the top surface of the telescopic unit is recessed in the direction of the bottom surface to form a receiving groove, and a bottom wall surface is defined, and the second opening is provided on the bottom wall surface; when the telescopic unit is in the second position, the receiving groove forms an implantation port that communicates with the outside.
[0013] Furthermore, when the telescopic unit is in the second position, the upper part of the receiving groove is covered by the pressing part, and the implantation port is formed by the side of the receiving groove.
[0014] Furthermore, when the telescopic unit is in the second position, the end edge of the second limiting part is flush with or lower than the bottom wall surface.
[0015] Furthermore, when the telescopic unit is in the first position, along a direction perpendicular to the first direction, the end of the first limiting part is located above the plane where the lower surface of the pressing part is located, and the end edge of the second limiting part is located between the plane where the top surface is located and the plane where the bottom wall surface is located.
[0016] Furthermore, it also includes a vibration mechanism, comprising a vibration unit and a transmission unit, wherein the transmission unit is connected to the implantation port of the receiving groove of the telescopic unit.

[0032] To make the objectives, technical solutions, and advantages of this application clearer, the following will provide a more detailed description of this application in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.
[0033] To illustrate the technical solution described in this application, specific embodiments are provided below.
[0034] In this application, all references to directions shall be in the form of... Figure 1The direction is taken as a reference, where the direction of the X-axis is defined as the first direction.
[0035] Please refer to Figures 1 to 9 As shown, this application discloses an automatic transfer device for micro-parts, which can be used to install micro-parts such as pressure rings 50 in small cooling fans (in this embodiment, pressure rings 50 are used as an example of micro-parts). The automatic transfer device for micro-parts includes a device bracket, a telescopic unit 21, a drive structure 10, a positioning unit 23, at least one elastic element 234, and a pressing part 221.
[0036] Specifically, the first fixing unit 22 is mounted on the equipment bracket, the telescopic unit 21 is movably mounted on the first fixing unit 22 and has a top surface 213 and a bottom surface 214, the telescopic unit 21 has a receiving cavity 211, and the receiving cavity 211 extends upward to form a first opening 2111 and a second opening 2112.
[0037] Specifically, the top surface 213 of the telescopic unit 21 is recessed towards the bottom surface 214 to form a receiving groove 212, and the receiving groove 212 defines a bottom wall surface 2121, and the second opening 2112 is provided on the bottom wall surface 2121.
[0038] Specifically, the drive structure 10 drives the telescopic unit 21 to reciprocate between a first position and a second position along a first direction on the first fixed unit 22. The first position is located on the portion of the telescopic unit 21 extending out of the first fixed unit 22, and the second position is located on the portion of the telescopic unit 21 retracted into the first fixed unit 22. In this embodiment, the drive structure 10 is an elongated cylinder, and the elongated cylinder is fastened to the telescopic unit 21 by screws.
[0039] Specifically, the positioning unit 23 is movably disposed inside the receiving cavity 211 and forms a first limiting part 232 and a second limiting part 233; at least one elastic element 234 is located inside the receiving cavity 211, and the elastic element 234 generates an upward thrust on the positioning unit 23, causing the first limiting part 232 to protrude upward through the first opening 2111 to above the top surface 213, while causing the second limiting part 233 to protrude upward through the second opening 2112; the pressing part 221 covers at least a portion of the top surface 213 of the first fixing unit 22. In this embodiment, the pressing part 221 is fastened to the first fixing unit 22 by screws.
[0040] Specifically, in this embodiment, the positioning unit 23 has a base 231, the elastic element 234 is disposed on the base 231, the first limiting part 232 and the second limiting part 233 are integrally formed, one end of the elastic element 234 is connected to the base 231, and the other end is connected to the first limiting part 232 and the second limiting part 233. The first limiting part 232 and the second limiting part 233 move up and down within the first opening 2111 and the second opening 2112. In this embodiment, the elastic element 234 is a spring.
[0041] Specifically, when the telescopic unit 21 moves from the first position to the second position, the first limiting part 232 is limited by the pressing part 221 and descends. The end 2321 of the first limiting part 232 abuts against the lower surface of the pressing part 221, thereby maintaining the end edge 2331 of the second limiting part 233 not higher than the lower surface of the pressing part 221.
[0042] Specifically, the side of the first limiting part 232 that contacts the pressing part 221 is an inclined surface, and the lowest point of the inclined surface is lower than the lower surface of the pressing part 221, so that the first limiting part 232 can easily limit the pressing part 221 and move it down to the second position.
[0043] Specifically, when the telescopic unit 21 is in the second position, the end edge 2331 of the second limiting part 233 is flush with or lower than the bottom wall surface 2121. When the telescopic unit 21 is in the first position, the end edge 2331 of the second limiting part 233 is located between the plane of the top surface 213 and the plane of the bottom wall surface 2121 in a direction perpendicular to the top surface 213. This ensures that when the telescopic unit 21 is in the second position, the end edge 2331 of the second limiting part 233 does not contact the pressing part 221 and will not cause wear. As a result, when the pressure ring 50 is sleeved on the second limiting part 233, no friction will occur, and the pressure ring 50 will not produce burrs or wear.
[0044] Specifically, the inner diameter D2 of the pressure ring 50 is slightly larger than the outer diameter (not shown) of the second limiting part 233, making it easy to assemble the pressure ring 50 onto the second limiting part 233.
[0045] Specifically, in this application, the automatic transfer device for the micro-parts further includes a vibration mechanism 30. The vibration mechanism 30 includes a vibration unit 31 and a transmission unit 32. The transmission unit 32 is connected to the implantation port 2123 of the receiving groove 212 of the telescopic unit 21. The pressure ring 50 vibrates through the vibration unit 31, passes through the transmission unit 32, and then enters the receiving groove 212 through the implantation port 2123 (the pressure ring 50 enters the receiving groove 212 through the vibration of the vibration unit 31 and is sleeved on the second limiting part 233). In this application, the vibration unit 31 can make the pressure ring 50 form a concave surface facing the transmission unit 212 through vibration.
[0046] Specifically, this application also includes a suction and release mechanism 40 for absorbing the pressure ring and placing it in the cooling fan. The suction and release mechanism 40 includes a main body 41, a cylinder 42, a second elastic element 43, and a positioning element 44. A gas channel is formed in the main body 41. One end of the main body 41 is connected to the cylinder 42, and the other end of the main body 41 is connected to the positioning element 44.
[0047] Specifically, the positioning element 44 protrudes from the main body 41, and the gas channel forms an opening 4112 at the periphery of the other end where it is connected to the positioning element 44. The gas from the cylinder 42 draws the pressure ring 50 onto the opening 4112 through the gas channel. The positioning element 44 is fitted with the second elastic element 43 for telescopic movement, and the diameter D1 of the positioning element 44 is equal to or less than the inner diameter D2 of the pressure ring 50, making it difficult for the pressure ring 50 to detach from the positioning element 44.
[0048] Specifically, the suction and release mechanism 40 further includes a third opening, which is formed in the center of the main body 41. The positioning element 44 is disposed inside the third opening, and the opening 4112 is arranged around the third opening. The second elastic element 43 is used to perform telescopic movement within the third opening.
[0049] The following describes the operating principle of the automated transfer device for the aforementioned micro-parts:
[0050] Step 1: Place the pressure ring 50 into the vibration unit 31. The pressure ring 50 is vibrated to form a concave surface facing upwards and enters the implantation port 2123 through the transmission unit 32.
[0051] Step 2: The drive structure 10 controls the telescopic unit 21 to retract inward to the second position on the first fixed unit 22. The first limiting part 232 abuts against the lower surface of the pressing part 221. The pressing part 221 compresses the elastic element 234, causing the first limiting part 232 and the second limiting part 233 to descend within the first opening 2111 and the second opening 2112. The pressure ring 50 enters the receiving groove 212 through the implantation port 2123.
[0052] Step 3: The drive structure 10 controls the telescopic unit 21 to move to the first position on the first fixed unit 22. When the first limiting part 232 leaves the pressing part 221, the elastic element 234 pushes out the first limiting part 232 and the second limiting part 233.
[0053] Step 4: When the drive structure controls the telescopic unit 21 to move to the first position, the positioning element 44 descends and presses against the second limiting part 233, causing it to descend and thus absorb the pressure ring 50.
[0054] Step 5: Cylinder 42 controls the positioning element 44 to rise, causing the telescopic unit 21 to move to the second position. Cylinder 42 then controls the positioning element 44 to descend, placing the pressure ring 50 at the designated position of the cooling fan.
[0055] In this way, the pressure ring 50 will not be damaged during the transmission process and will not easily fall off, saving labor costs.
[0056] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this application.
[0057] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
