Description

Technical Field

[0001] This application belongs to the field of automated equipment, specifically relating to a device for assembling 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 the core components inside the equipment and avoid problems such as the equipment failing to function properly due to overheating.

[0003] Cooling fans in electronic products are very small, especially those used in small electronic devices such as mobile phones, tablets, and portable cameras. Assembling the bearings is a crucial part of the cooling fan assembly process. The bearings inside a cooling fan are typically metal tubes with an outer diameter of 3-5 mm and an axial height of 2-6 mm. Due to their small size, the conventional assembly method in industrial production involves manually picking them up with tweezers and assembling them into the cooling fan's shaft tube. This method is extremely inefficient. Furthermore, the manual assembly method requires manually picking and handling the semi-finished fan with the bearings to be assembled. The tilt angle and speed of this handling cannot be controlled, which can lead to the displacement or falling of other parts on the semi-finished fan, making it difficult to guarantee product yield.

[0004] Therefore, a new device needs to be designed to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this application is to provide a device for assembling small parts, which can automatically assemble small parts, especially bearings inside cooling fans.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0016] When the first slider is in the first position, the drive rod is located directly above the first receiving hole. The first receiving hole, the second receiving hole, and the guide hole are connected along the second direction. One end of the drive rod can be inserted into and pass through the first receiving hole, the second receiving hole, and the guide hole in sequence, and protrude downward to the outside of the guide hole.

[0017] Furthermore, when the first slider is in the second position, the first receiving hole and the second receiving hole are misaligned and not connected. The lower opening of the first receiving hole is blocked by the first bearing plate, and the second receiving hole is connected to the guide through hole.

[0018] Furthermore, the fixing block includes a fixing base and an extension formed by the fixing base extending downward along the second direction;

[0019] The guide hole penetrates the fixed base and the extension along the second direction;

[0020] The sliding block is fitted around the periphery of the extension.

[0021] Furthermore, the extension has several notches formed thereon, and the inner wall surface of the extension forms part of a guide hole;

[0022] The sliding block has an insertion hole formed through it along the second direction, and the extension is inserted into the insertion hole;

[0023] The sliding block protrudes into the insertion hole to form a filling part that can extend into the notch, and the inner wall surface of the filling part forms part of the guide through hole.

[0024] Furthermore, the length of the notch along the second direction is equal to that of the extension.

[0025] Furthermore, it also includes a second drive unit, which has a fixed arm capable of reciprocating along the second direction. The sliding block is fixed to the fixed arm, and the fixed arm drives the sliding block to slide relative to the fixed block within a set range along the second direction.

[0026] Furthermore, two notches are formed and are arranged opposite each other along the radial direction of the guide hole.

[0027] Furthermore, the arc length of the notch along the circumferential direction of the guide hole is one-quarter of the circumference of the guide hole.

[0028] Furthermore, the insertion hole includes a mating section hole and a guide section hole communicating with the mating section hole, the extension portion is correspondingly mated with the mating section hole, the filling portion is formed in the mating section hole, and the guide section hole forms one section of the guide through hole.

[0043] 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.

[0044] To illustrate the technical solutions described in this application, specific embodiments are provided below. Furthermore, for the sake of accuracy throughout the entire description, all directions referred to herein shall be interpreted as follows: Figure 1 For reference, the direction of the X-axis is defined as the first direction; the direction of the Z-axis is defined as the second direction (i.e., the up-down direction, where the positive direction of the Z-axis is up); and the direction of the Y-axis is defined as the third direction.

[0045] Please see Figures 1 to 12 The diagram illustrates a micro-parts assembly device disclosed in this application. Used in conjunction with an automated production line, it is primarily for the automatic transfer and assembly of micro-parts, particularly suitable for assembling bearings in small cooling fans. The micro-parts assembly device includes a frame 1, a first moving unit (not labeled) fixed to the frame 1, a first drive unit 3, a transfer module 5, and a second drive unit 6. Alternatively, the micro-parts assembly device may also include a parts transfer unit 4 for coordinated use. The micro-parts assembly device is mainly used to automatically transfer and assemble micro-parts (such as bearings) into semi-finished components 7 (semi-finished fans with bearings to be assembled).

[0046] Please refer to Figure 2 and Figure 3 As shown, the first moving unit includes a first support plate 21, a first slider 22, and a first driving mechanism 23. The first support plate 21 is assembled and fixed to the frame 1 (or directly integrally formed on the frame 1). A slide rail portion 212 extending along a first direction is formed on the first support plate 21. The first slider 22 is slidably assembled on the slide rail portion 212. The first driving mechanism 23 is fixed to the frame 1 and is used to drive the first slider 22 to reciprocate between a first position and a second position along the first direction on the first support plate 21.

[0047] In the illustrated embodiment of this application, the slide rail portion 212 is an elongated groove formed by the downward indentation of the upper surface of the first bearing plate 21 (see reference). Figure 3 (As shown). The first slider 22 is elongated and directly inserted into the slide rail 212. Two limiting plates 24 are placed on the edge of the upper surface of the first slider 22 to limit its position. The limiting plates 24 are locked to the first support plate 21 by screws.

[0048] The first slider 22 has a first receiving hole 221 extending through it along a second direction. The first support plate 21 has a second receiving hole 211 extending through it along the second direction. When the first slider 22 is in the first position, the first receiving hole 221 is directly above the second receiving hole 211 and they are interconnected. When the first slider 22 is in the second position, the first receiving hole 221 and the second receiving hole 211 are misaligned and not interconnected, and the lower opening of the first receiving hole 221 is blocked by the inner side of the slide rail portion 212 of the first support plate 21.

[0049] Please refer to the reference. Figures 1 to 3 and Figure 5 As shown, the part transfer unit 4 is used in conjunction with the first moving unit. Specifically, the part transfer unit 4 is provided with a part transfer tube 42. A transfer head 40 is installed at one end of the part transfer tube 42. The transfer head 40 forms an open discharge port 41. The discharge port 41 is attached to the upper surface of the first slider 22. When the first slider 22 is in the second position, the first receiving hole 221 is located directly below the discharge port 41, and the part transfer unit 4 inserts a single small part (such as a bearing) into the first receiving hole 221 through the part transfer tube 42 and the discharge port 41.

[0050] Please refer to the reference. Figure 1 , Figures 6 to 12 As shown, the conveying module 5 is assembled and fixed or integrally combined with the lower part of the first support plate 21, specifically located directly below the second receiving hole 211. The conveying module 5 has a guide hole 50 formed through it along the second direction, and the guide hole 50 communicates with the second receiving hole 211. The conveying module 5 includes a fixing block 51 and a sliding block 52 nested with the fixing block 51. The fixing block 51 is fixed or integral with the first support plate 21. The sliding block 52 can slide relative to the fixing block 51 within a set range along the second direction, and the guide hole 50 is formed by penetrating the fixing block 51 and the sliding block 52 along the second direction.

[0051] Specifically, the fixing block 51 includes a fixing base 511 and an extension 512 formed by the fixing base 511 extending downward along the second direction. The guide hole 51 penetrates the fixing base 511 and the extension 512 along the second direction. The sliding block 52 is sleeved around the extension 512. In this application, the extension 512 has two notches 5121 formed thereon, and the inner wall surface 5122 of the extension 512 forms a part of the guide hole 51. The sliding block 52 has an insertion hole 521 formed through it along the second direction, and the extension 512 is inserted into the insertion hole 521. The sliding block 52 protrudes into the insertion hole 521 to form a filling part 522 that can protrude into the notch 5121, and the inner wall surface 5221 of the filling part 522 forms a part of the guide hole 51.

[0052] In this application, the fixed block 51 is immovable. When the sliding block 52 moves upward relative to the fixed block 51 to the highest position (e.g., Figure 10 (In the display state), the extension 512 is fully engaged with the insertion hole 521, and the notch 5121 is fully engaged with the filling part 522, so that the inner wall surface 5122 of the extension 512 and the inner wall surface 5221 of the filling part 522 together form a complete section of the guide hole 51.

[0053] When the sliding block 52 moves downward relative to the fixed block 51 to the lowest position (e.g.) Figure 10 In the demonstration state, the extension 512 is adjacent to the insertion hole 521 along the second direction (or partially engaged along the second direction), and the notch 5121 is adjacent to the filling part 522 along the second direction (or partially engaged along the second direction); this allows the inner wall surface 5122 of the extension 512 to independently form one section (in the second direction) of the guide hole 51, thus independently accommodating a small part; the inner wall surface 5221 of the filling part 522 independently forms the other section (in the second direction) of the guide hole 51, thus independently accommodating a small part. This gives the guide hole 50 formed on the transfer module 5 a similar telescopic effect along the second direction.

[0054] Please refer to Figure 1 and combined Figure 12As shown, the second drive unit 6 is fixed to the frame 1 and has a fixed arm 61 that can reciprocate along the second direction. The sliding block 52 is fixed to the fixed arm 61, and the fixed arm 61 drives the sliding block 52 to slide relative to the fixed block 51 along the second direction within a set range. In this application, preferably: the length of the notch portion 5121 along the second direction is equal to that of the extension portion 512; two notches 5121 are formed and are arranged opposite each other along the radial direction of the guide hole 51; the arc length of the notch portion 5121 along the circumference of the guide hole 51 is one-quarter of the circumference of the guide hole 51. This design is used to adjust the structural strength of each position of the transmission module 5, and at the same time, it enables the guide hole 51 to be positioned more accurately for the small parts (such as bearings) to be transmitted in each state.

[0055] Please refer to the reference. Figures 6 to 10 As shown, the insertion hole 521 includes a mating section hole 5211 and a guide section hole 5212 communicating with the mating section hole 5211. The extension portion 512 mates with the mating section hole 5211. The filling portion 522 is formed inside the mating section hole 5211. The inner wall surface of the guide section hole 5212 forms a complete section of the guide through hole 51 along the second direction. The guide section hole 5212 is a circumferentially closed complete through hole structure. By setting a complete guide section hole 5212 at the lowest position of the sliding block 52 (that is, the end of the guide through hole 51), and designing the inner diameter of the guide section hole 5212 to match the outer diameter of the micro part to be transferred (such as a bearing), the micro part to be transferred can be guided and adjusted to the end position of the guide through hole 51, so that the micro part to be transferred from the end opening of the guide through hole 51 can be more accurately assembled into the semi-finished device (such as a semi-finished fan with a bearing to be assembled).

[0056] Please refer to Figure 4 and combined Figure 1 As shown, the first drive unit 3 is assembled and fixed on the frame 1, and includes a drive rod 31 that can reciprocate along a first direction. When the first slider 22 is in the first position, the drive rod 31 is located directly above the first receiving hole 221. The first receiving hole 221, the second receiving hole 211, and the guide hole 51 are connected along a second direction. One end of the drive rod 31 can be inserted into and pass through the first receiving hole 221, the second receiving hole 211, and the guide hole 51 in sequence, protruding downwards to the outside of the guide hole 51. During this process, the drive rod 31 can smoothly push the small parts out of the guide hole 51 to achieve assembly.

[0057] By using the micro-parts assembly equipment of this application, the automatic transfer and assembly of micro-parts can be achieved, which is particularly suitable for the assembly of bearings in small cooling fans. The micro-parts assembly equipment of this application has a simple structure, is easy to assemble, and has strong stability, making it very suitable for large-scale industrial production.

[0058] 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.

[0059] 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.
