[0003] Assembling a fan and its bracket requires identifying the fan's airflow direction and the direction of its wiring. An incorrect airflow direction will result in poor heat dissipation, causing the device temperature to exceed its rated value; incorrect wiring will prevent the fan connector from connecting, leading to product rework. In related technologies, these identification processes are primarily done manually, which is time-consuming, labor-intensive, and prone to errors, resulting in rework.

[0004] In addition, when the fan bracket is fastened to the fan, the fan bracket will rotate, requiring manual straightening of the bracket, which causes unnecessary movements and reduces the efficiency of fan assembly. Utility Model Content

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and 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.

[0023] like Figure 1 As shown, one embodiment of this specification provides a fan 4 assembly error prevention tooling, including a base plate 1, an assembly station 21 provided on the base plate 1, a placement slot 2 adapted to the fan 4 provided on the assembly station 21, and a limit component and an anti-rotation component provided on the assembly station 21. The limiting component is disposed on one side of the placement slot 2. The limiting component includes a limiting seat 3 and a limiting part for limiting the fan 4. The limiting seat 3 is fixed on the base plate 1, and the limiting part is disposed on the side of the limiting seat 3 near the placement slot 2. The anti-rotation component is disposed on one side of the placement slot 2. The limiting component and the anti-rotation component are respectively located on different sides of the placement slot 2. The anti-rotation component includes an anti-rotation seat 5 and an anti-rotation part for preventing the fan bracket 6 from rotating. The anti-rotation seat 5 is fixed on the base plate 1, and the anti-rotation part is disposed on the top of the anti-rotation seat 5.

[0024] In the above technical solution, the assembly station 21 on the base plate 1 can conveniently and effectively assemble the fan 4 and the fan bracket 6. The limiting part on the limiting seat 3 limits the fan 4 to be assembled. If the fan 4 is installed backward or the wiring direction is wrong, the fan 4 will not be able to be placed in the placement slot 2, and the fan bracket 6 will not be able to be installed. The design of the limiting part can ensure that the fan 4 to be assembled is correctly placed in the placement slot 2, thereby ensuring the correctness of the air blowing direction of the fan 4 and the wiring direction of the fan 4. During assembly, the fan bracket 6 is placed on the anti-rotation seat 5. During the assembly process, the anti-rotation part on the anti-rotation seat 5 can prevent the fan bracket 6 from rotating. The above technical solution can effectively prevent mistakes, eliminate the need for manual identification, save time and effort, reduce labor input, avoid assembly rework, and greatly improve the assembly efficiency of the fan 4.

[0025] Figure 1 and Figure 2 The following are three-dimensional schematic diagrams of the fan 4 assembly error-proof fixture from different perspectives in this embodiment. Figure 1 The assembly station 21 of the tooling places the fan 4 and the fan bracket 6, which can more intuitively demonstrate the actual assembly and use of the tooling.

[0026] This technical solution can also prevent mistaken welding of the 4PV wires (i.e., 4 lead wires) of the fan. It can improve the accuracy of assembly in one go by limiting the position, improve work efficiency, and avoid test failure or product damage caused by reversed welding of PV wires.

[0027] As a preferred technical solution, the limiting part includes a limiting boss 7 located directly above the edge of the placement groove 2. The limiting boss 7 is adapted to the limiting groove 8 on the fan 4, and only one limiting groove 8 is provided on the fan 4.

[0028] In this embodiment, after the fan 4 to be assembled is correctly placed into the placement slot 2, the limiting boss 7 located directly above the edge of the placement slot 2 fits into the limiting groove 8 on the fan 4. Since only one limiting groove 8 is provided on the fan 4 to be assembled, if the fan 4 is installed backwards or the wiring direction is incorrect, the fan 4 will not be able to be placed into the placement slot 2, and the fan bracket 6 will not be able to be installed. This embodiment adopts a structural design in which the limiting boss 7 and the limiting groove 8 are adapted, which has a good foolproof effect, and the structure of the fan 4 is modified little, which is convenient for production.

[0029] This embodiment utilizes the feature of the limiting groove 8 of the fan 4 to design and manufacture a foolproof assembly fixture for the fan 4. The limiting boss 7 on the fixture is used for limiting, which can ensure the accuracy of the air blowing direction of the fan 4 and the wiring direction of the wires.

[0030] In practice, in addition to the aforementioned limiting boss 7, the limiting part can be adjusted to other limiting designs according to actual needs. For example, the limiting part on the limiting seat can be set as a groove, and a boss that matches the groove can be set on the fan. Alternatively, a corresponding limiting feature (such as a boss) can be set directly in the placement slot, and a groove that matches the boss can be set on the fan.

[0031] As a preferred technical solution, the anti-rotation part includes an anti-rotation slot 9 that is adapted to the fan bracket 6.

[0032] In this embodiment, the anti-rotation part is set as an anti-rotation slot 9 that is adapted to the fan bracket 6. When assembling, the fan bracket 6 is snapped into the anti-rotation slot 9, which can effectively prevent the fan bracket 6 from rotating during the assembly process. There is no need to manually straighten the fan bracket 6, which effectively saves labor.

[0033] In practice, in addition to the anti-rotation slot 9 mentioned above, the anti-rotation part can also be adjusted to other anti-rotation designs according to actual needs. For example, the anti-rotation part on the anti-rotation seat can be set as a boss, and a slot that matches the boss can be set on the fan bracket.

[0034] As a preferred technical solution, the limiting component and the anti-rotation component are respectively provided on the two adjacent sides outside the placement slot.

[0035] The placement slot 2 is adapted to the fan 4. In this embodiment, the fan 4 is square, so the placement slot 2 is correspondingly set as a square placement slot 2. The limiting component and the anti-rotation component are respectively provided on the outer sides of the two adjacent right-angled sides of the square placement slot 2.

[0036] In this embodiment, the placement slot 2 adopts a square placement slot 2, which can facilitate the placement of the square fan 4 to be assembled. The limiting component and the anti-rotation component are respectively set on the outside of the two adjacent right-angled sides of the square placement slot 2, which not only makes the structure compact and saves space, but also facilitates the assembly of the fan 4.

[0037] In practice, the specific shape of the placement slot 2 can be adjusted according to the actual shape of the fan 4 to be assembled. This embodiment uses a square placement slot 2 as an example for illustration.

[0038] As a preferred technical solution, the limiting seat 3 includes a first limiting block 10 and a second limiting block 11. The first limiting block 10 is fixed on the base plate 1 and is located in the middle of one side outside the square placement groove 2. The second limiting block 11 is vertically connected to one side of the top of the first limiting block 10. The limiting boss 7 is provided on the side of the second limiting block 11 near the placement groove 2. A wiring groove 12 for the wiring of the fan 4 is formed between the second limiting block 11 and the base plate 1.

[0039] To better prevent the fan 4 from being installed backwards or the wiring direction from being incorrect, the limiting seat 3 in this embodiment includes a first limiting block 10 and a second limiting block 11. The first limiting block 10 and the second limiting block 11 form an L-shaped seat. A limiting boss 7 is provided on the side of the second limiting block 11 near the placement slot 2, so that the limiting boss 7 is located directly above the edge of the placement slot 2, which facilitates the limiting of the fan 4 to be assembled. The limiting seat 3 adopts an L-shaped seat design, which allows the second limiting block 11 and the base plate 1 to form a wiring groove 12 with an opening on one side. When the fan 4 to be assembled is placed into the placement slot 2, the wire of the fan 4 is routed through the wiring groove 12, which further ensures the correctness of the wiring direction of the fan 4 wire.

[0040] As a preferred technical solution, the side of the limiting seat 3 near the square placement groove 2 is flush with the side wall of the square placement groove 2.

[0041] In this embodiment, the side of the L-shaped limiting seat 3 near the square placement slot 2 is flush with the side wall of the square placement slot 2. This structural design can make the side of the limiting seat 3 near the square placement slot 2 a placement guide surface, which makes it easier to put the fan 4 into the square placement slot 2. It also makes it easier to set a limiting boss 7 on the limiting seat 3 located directly above the edge of the placement slot 2.

[0042] As a preferred technical solution, the anti-rotation slot 9 is an open slot that runs through both sides. The open slot has a first side wall 13 and a second side wall 14 that are opposite each other. The first side wall 13 is flush with one side wall of the square placement slot 2, and the plane of the second side wall 14 passes through the middle of the square placement slot 2.

[0043] In this embodiment, the anti-rotation slot 9 is set as an open slot that runs through both sides, which makes it easy to insert the fan bracket 6 into the anti-rotation slot 9 during assembly. During assembly (tightening screw 20), the anti-rotation slot 9 can effectively prevent the fan bracket 6 from rotating.

[0044] When assembling the fan bracket 6 onto the fan 4, it is also necessary to identify the orientation of the fan bracket 6; if the fan bracket 6 is installed in the wrong orientation, the fan 4 will not be able to be installed on the equipment, resulting in product rework. To prevent the fan bracket 6 from being installed backwards, the anti-rotation slot 9 in this embodiment adopts a special position design, such as... Figure 3 As shown, the first side wall 13 of the anti-rotation slot 9 is flush with one side wall of the square placement slot 2, and the plane of the second side wall 14 passes through the middle of the square placement slot 2. That is, the position of the anti-rotation slot 9 is biased to one side, so that the anti-rotation slot 9 is not directly facing the middle of the square placement slot 2, but directly facing one side of the square placement slot 2. With this positional design, the fan bracket 6 cannot be fixed to the fan 4 when it is installed backwards, thus effectively preventing the fan bracket 6 from being installed backwards.

[0045] As a preferred technical solution, the base plate 1 is provided with a plurality of assembly stations 21, the assembly stations 21 are arranged in a matrix, and each assembly station 21 is provided with the placement slot 2, the limiting component and the anti-rotation component.

[0046] In the prior art, only one product can be assembled at a time during fan 4 assembly, resulting in wasted motion and low production efficiency. To improve assembly efficiency, this embodiment sets up several assembly stations 21 on the tooling base plate 1, allowing several fan 4 products to be assembled simultaneously. The assembly stations 21 are arranged in a matrix, which not only makes the structure compact and saves space, but also facilitates the actual fan 4 assembly work.

[0047] In practice, the tooling base plate 1 of this embodiment has 8 installation positions arranged at the same time, which can assemble 8 fan 4 products at one time, greatly improving the assembly efficiency of fan 4.

[0048] The overall design of any assembly station 21 of the fan 4 assembly error-proof fixture in this embodiment can be referred to. Figure 5 As shown.

[0049] It should be noted that the processing method of the fan 4 assembly error-proof tooling in the above embodiments is not limited (it can be integrally molded or disassembled and spliced), and the material of the tooling is also not limited, and can be selected according to actual production needs.

[0050] like Figure 6 As shown, one embodiment of this specification also provides a fan 4 device, including a fan 4 and a fan bracket 6 adapted to the aforementioned fan 4 assembly error prevention tooling. The fan 4 has a square fan seat 15 adapted to the square placement slot 2, and one side of the square fan seat 15 is provided with a limiting groove 8 adapted to the limiting boss 7.

[0051] In this embodiment, the design of the fan 4 assembly error-proof fixture is compatible with the design of the fan 4 and the fan bracket 6. The fan 4 to be assembled in this embodiment is a square fan 4 with a square fan base 15. During assembly, part of the square fan base 15 can be just inserted into the square placement groove 2 on the fixture base plate 1. The square fan base 15 is provided with a limiting groove 8 that matches the limiting boss 7 on only one side. In this way, the matching and limiting of the limiting boss 7 and the limiting groove 8 can ensure that the fan 4 to be assembled is correctly placed into the placement groove 2, thereby ensuring the correctness of the air blowing direction of the fan 4 and the routing direction of the fan 4 wires.

[0052] like Figure 6As shown, when the upper limit groove 8 of the fan 4 is aligned with the upper limit boss 7 of the limit seat 3, the fan 4 can be placed into the square placement slot 2 of the base plate 1; when the upper limit groove 8 of the fan 4 is not aligned with the upper limit boss 7 of the limit seat 3, the fan 4 cannot be placed into the square placement slot 2 of the base plate 1; thus, it serves to prevent the fan 4 from blowing in the wrong direction and the wire routing direction.

[0053] In practice, the tooling base plate 1, the placement slot 2, and the limiting components (limiting seat 3, limiting boss 7) on the tooling can be adjusted according to the size and shape of the fan 4 to be assembled; the anti-rotation components (anti-rotation seat 5, anti-rotation slot 9) on the tooling can also be adjusted according to the size and shape of the fan bracket 6.

[0054] like Figure 4 As shown, in a preferred embodiment, the fan bracket 6 includes a first fixing plate 16, a connecting plate 17, and a second fixing plate 18. The connecting plate 17 connects the first fixing plate 16 and the second fixing plate 18, and the first fixing plate 16 and the connecting plate 17 are located on the same plane. The second fixing plate 18 is vertically connected to the side of the connecting plate 17 away from the first fixing plate 16. The width of the first fixing plate 16 is adapted to the width of the square fan base 15. The width of the connecting plate 17 is the same as that of the second fixing plate 18 and smaller than the width of the first fixing plate 16. The connecting plate 17 is connected to one side of one end of the first fixing plate 16. The first fixing plate 16 is threaded to one end of the square fan base 15. An arc-shaped opening 19 adapted to the air outlet of the fan 4 is provided on the side of the first fixing plate 16 away from the connecting plate 17. The second fixing plate 18 is used to fix the fan bracket 6. The connecting plate 17 is adapted to the anti-rotation slot 9.

[0055] In this embodiment, the fan bracket 6 includes a first fixing plate 16, a connecting plate 17, and a second fixing plate 18. This design is compatible with the design of the fan 4 and the foolproof tooling. The first fixing plate 16 can be fixed to one end of the square fan base 15 with two screws 20. An arc-shaped opening 19 is provided on the first fixing plate 16 to facilitate airflow. The second fixing plate 18 can fix the fan bracket 6 to the corresponding equipment (or designated position). The width of the first fixing plate 16 is compatible with the width of the square fan base 15, which facilitates fixing the square fan base 15 to the first fixing plate 16. The connecting plate 1 in this embodiment... 7 is adapted to the anti-rotation slot 9, and the connecting plate 17 can be inserted into the anti-rotation slot 9. The connecting plate 17 and the second fixing plate 18 have the same width and are smaller than the width of the first fixing plate 16. The connecting plate 17 is connected to one side of one end of the first fixing plate 16. This structural design allows the connecting plate 17 and the second fixing plate 18 to be biased towards one side of the first fixing plate 16, thus adapting to the aforementioned opening slot (anti-rotation slot 9) design. When the fan bracket 6 is installed backwards, the mounting holes on the fan bracket 6 and the mounting holes on the square fan seat 15 will not be aligned, and the fan bracket 6 cannot be assembled, thereby achieving the anti-mistaken installation of the fan bracket 6 backwards.

[0056] In specific implementation, the two ends of the first fixing plate 16 can be respectively equipped with a barrier 22. The barrier 22 can be formed by bending. After assembly, the fan 4 is located between the two barriers 22. The addition of the barrier 22 can make the fan 4 better fixed on the fan bracket 6.

[0057] like Figure 6 As shown, the fan bracket 6 is placed into the anti-rotation slot 9 on the anti-rotation seat 5, which can limit the rotation of the fan bracket 6 when the fastening screw 20 is tightened; as Figure 7 As shown, when the fan bracket 6 is installed backwards, the mounting holes of the fan 4 and the screw 20 of the fan bracket 6 will not align. Therefore, the anti-rotation slot 9 design in this embodiment can effectively prevent the fan bracket 6 from being installed backwards, thus preventing mistaken installation.

[0058] This embodiment provides a fan assembly error-proof fixture. This fixture is compatible with the fan and fan bracket. Through fixture positioning, it effectively prevents incorrect assembly of the fan and fan bracket, avoiding rework due to misassembly. This not only improves production efficiency but also increases the first-pass yield. Specifically: 1. To prevent the fan from blowing in the wrong direction or the wire from being routed in the wrong direction, the fixture is designed with a limiting feature (i.e., a limiting boss) to match the groove feature (i.e., a limiting groove) on the fan, so as to prevent mistaken installation. If the fan is installed backward or the wire is routed in the wrong direction, the fan will not be able to be placed in the placement slot on the fixture base plate, and the fan bracket will not be able to be installed. 2. To prevent the fan bracket from rotating and being installed backwards, the tooling is designed with anti-rotation features (i.e., anti-rotation slots). When the screws are tightened, the fan bracket will be restricted from rotating. When the fan bracket is installed backwards, the mounting holes on the fan bracket and the mounting holes on the fan will not be aligned, and the fan bracket cannot be assembled, thus achieving the goal of preventing the fan bracket from being installed backwards.

[0059] 3. To improve assembly efficiency, eight assembly stations are arranged on the tooling base plate at the same time, allowing eight fan products to be assembled at the same time, reducing the need to pick up and put down materials and tools, and greatly improving the fan assembly efficiency.

[0060] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0061] The parts not mentioned in the above embodiments are the same as or can be implemented using existing technologies, and will not be further described here.

[0062] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
