Description

Technical Field

[0001] This application relates to the field of cooling fan manufacturing technology, and in particular to an assembly line for cooling fans. Background Technology

[0002] The assembly of existing cooling fans is usually done manually or mechanically by assembling the various components of the cooling fan one by one. Since cooling fans have many parts, a large number of workstations are required during the assembly process. When assembling cooling fans, power cords are also involved. If the power cords are too long, they can easily cause the cooling fan to deviate or obstruct normal transport. If each workstation needs to be equipped with at least one worker or robot to push or prevent the cooling fan from deviating, the cost of assembly will be higher. Furthermore, when using robots for assembly, it is easy to block or hinder the normal operation of the robots. As a result, the yield rate of finished cooling fans is low and cannot meet the needs of development. Summary of the Invention

[0003] To address the aforementioned issues, this application provides an assembly line for cooling fans.

[0004] The assembly line for cooling fans provided in this application adopts the following technical solution: An assembly line for cooling fans includes a conveyor belt and assembly stations. The conveyor belt has an inlet and an outlet at its two ends. The assembly stations are located within the conveying range from the inlet to the outlet. Each assembly station includes a dispensing station, a pressing station, a wear-resistant sheet installation station, a buckle installation station, a bearing installation station, a fan blade installation station, a cover installation station, and an inspection station, all spaced at predetermined intervals. The line also includes several assembly carriers. A set of assembly carriers is spaced at predetermined intervals on the conveyor belt. The assembly carriers are conveyed from the inlet to the outlet, passing through each station sequentially, providing support for part assembly. Each assembly carrier includes a carrier body and a wire carrier. The carrier body has an assembly groove for part assembly. The wire carrier surrounds the carrier body and has an arc-shaped groove for placing power cables. The arc-shaped groove communicates with the assembly groove, and the end of the arc-shaped groove has a latch for the power cable plug to extend.

[0005] By adopting the above technical solution, the basic components of the cooling fan are placed on an assembly carrier. The assembly carrier is transported from the feeding end to the discharging end by a conveyor belt. During the transport process, the components are assembled sequentially through the dispensing station, pressing station, wear-resistant sheet installation station, buckle installation station, bearing installation station, fan blade installation station, and top cover installation station. Finally, the cooling fan is inspected at the inspection station to determine whether it is qualified. During the transport process, the components are gradually formed in the assembly groove of the carrier body. The carrier body restricts the installation position of the components and avoids the loading position deviation. The wires are placed in the arc-shaped groove of the wire carrier at the same time, so that the wires are wound around the surface of the carrier body through the arc-shaped groove, so that the wires do not stick out or swing outside at will, thereby preventing the wires from affecting the loading of the components.

[0006] Optionally, the carrier body is further provided with a clamping mechanism, which provides for fixing the parts during assembly.

[0007] By adopting the above technical solution, a clamping mechanism is set in the carrier body to clamp the parts and prevent them from shifting.

[0008] Optionally, the clamping mechanism includes a driving part, a clamping part, an elastic part, and a guiding part; the carrier body also has an installation cavity, and the installation cavity communicates with the assembly groove, the driving part is installed in the installation cavity; the driving part extends out to a driving end, and the driving end is provided with the guiding part; the clamping part is sleeved with the guiding part and slides along the guiding part; the driving part is also provided with an elastic part; the elastic part is connected to the clamping part and provides elastic force to the clamping part away from the driving part, and the clamping part extends into the assembly groove to clamp the part.

[0009] By adopting the above technical solution, the clamping part clamps the part, and there are two clamping methods. One is to use the elastic force of the elastic part to make the clamping part move along the guide part to flexibly clamp the part in the assembly slot. At this time, the end of the guide part away from the drive part does not contact the clamping part. The other is that the drive part drives the guide part, so that the guide part pushes the clamping part, so that the clamping part is subjected to the thrust and directly clamps the part in the assembly slot rigidly. These two methods provide different processing environments.

[0010] Optionally, both the clamping part and the guide part have a sound-silencing layer on their surfaces.

[0011] By adopting the above technical solution, when the clamping part and the guide part collide with each other during shaking, the sound-absorbing layer ensures that the two parts do not make noise when in contact, thereby improving the accuracy of shaking noise detection.

[0012] Optionally, the wire carrier includes a fixing part, a pivoting part, and a wire-clamping part; the fixing part is fixedly connected around the carrier body; the pivoting part is pivotally connected to the carrier body; the wire-clamping part is installed on the pivoting part and abuts against the fixing part, and the arc-shaped groove is formed in the wire-clamping part.

[0013] By adopting the above technical solution, after the workers or robots at the testing station lift the carrier body using the wire clamping part, it is convenient to carry out finished product testing such as shaking and abnormal noise testing, power supply testing, and wind force testing. At the same time, the wire is located in the arc groove, so that when the carrier body rotates along the pivot part, the wire clamping part and the internal wire will not be affected. When assembling parts, the wire clamping part is located on the fixed part and will not interfere with or obstruct other assembly stations.

[0014] Optionally, the wire clamping part is further provided with a detection groove, which is connected to the arc-shaped groove, and a pulling detection mechanism is provided in the arc-shaped groove.

[0015] By adopting the above technical solution, the tensile testing mechanism is used to provide stability testing of the connection between the wire and the assembly parts, mainly to prevent the connection between the wire and the parts from being unstable and breaking when pulled, so as to improve the pass rate of the connection between the wire and the parts.

[0016] Optionally, the tension detection mechanism includes a tension detection part, a pushing part, a limiting part, and a locking part; the guiding part is embedded in the locking part and communicates with the detection groove; the pushing part extends through the guiding part into the detection groove; the limiting part is installed on the top surface of the fixing part, and the bottom of the arc-shaped groove is also provided with an insertion port. When the locking part abuts against the fixing part, the limiting part extends through the insertion port into the arc-shaped groove and blocks the detection groove; the detection groove is provided with the locking groove; the locking part is sleeved on the pushing part and locks with the adjusting groove; the pushing part is provided with a pushing protrusion, one end of the tension detection part is connected to the pushing protrusion, and the other end is connected to the locking part.

[0017] By adopting the above technical solution, when a pull test is required on the wire, the assembly carrier moves to the testing station, and the robot arm at the testing station lifts the locking part. When the locking part is lifted, the limiting part disengages from the arc-shaped groove, so that the limiting part no longer blocks the testing groove. Without the blocking of the limiting part, the testing elastic part applies an elastic force to the pushing part in the direction of the arc-shaped groove by pushing the protrusion and the locking part, thereby causing the pushing part to move along the testing groove and the conductive part, pushing the wire, so that the wire is pulled by the elastic force. One end of the wire is fixed by the part, and the plug at the other end is locked by the bayonet, thereby realizing the pull test of the wire.

[0018] Optionally, the number of the snap-fit ​​slots is set to a certain number, the snap-fit ​​part snaps into any of the snap-fit ​​slots, and the bottom end of the snap-fit ​​part is also provided with an adjustment port.

[0019] By adopting the above technical solution, the snap-fit ​​part can be disengaged from the snap-fit ​​slot through the adjustment port. At the same time, depending on the snap-fit ​​part being inserted into different adjustment ports, the elastic force generated by the detection spring part will be different, thereby adjusting the magnitude of the detection spring force on different wire specifications in turn.

[0020] Optionally, the cable clamp may also be equipped with a wind detection mechanism.

[0021] By adopting the above technical solution, when the assembly carrier moves to the testing station, the robot arm at the testing station will lift the wire clamping part and the wind power testing mechanism synchronously along the pivot part, so that the wind power testing mechanism is directly below the assembled cooling fan. At this time, the electrician or robot arm can provide the power plug to supply power, and the cooling fan can blow on the wind power testing mechanism to perform wind power testing.

[0022] Optionally, the wind detection mechanism includes an impeller anemometer and a noise sensor; the impeller anemometer is installed on the cable clamp, and the noise sensor is installed on the impeller anemometer or the cable clamp.

[0023] By adopting the above technical solution, the impeller anemometer faces the cooling fan when the clamping part is lifted. This allows the wind force to be detected when the cooling fan is powered on. The noise sensor has two main functions: first, to provide noise detection when shaking or making abnormal noise, thus determining whether there is any abnormal noise; and second, to detect wind noise. When the cooling fan is powered on, the noise sensor detects whether there is any wind noise, thereby providing multiple data detection effects and improving the yield rate.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Place the basic components of the cooling fan on the assembly carrier. The assembly carrier is transported from the feeding end to the discharging end by a conveyor belt. During the transport, the components are assembled sequentially through the dispensing station, pressing station, wear-resistant sheet installation station, buckle installation station, bearing installation station, fan blade installation station, and top cover installation station. Finally, the cooling fan is inspected at the inspection station to determine if it is qualified. During the transport, the components are gradually formed in the assembly groove of the carrier body. The carrier body restricts the installation position of the components to avoid loading position deviation. The wires are placed in the arc-shaped groove of the wire carrier at the same time, so that the wires are wound along the surface of the carrier body through the arc-shaped groove, so that the wires do not stick out or swing outside, thereby preventing the wires from affecting the loading of the components. 2. A clamping mechanism is installed inside the carrier body to clamp the parts and prevent them from shifting. 3. The clamping part clamps the part, and there are two clamping methods. One is to use the elastic force of the elastic part to move the clamping part along the guide part to flexibly clamp the part in the assembly slot. In this case, the end of the guide part away from the drive part does not contact the clamping part. The other is that the drive part drives the guide part, so that the guide part pushes the clamping part, so that the clamping part is subjected to the thrust and directly clamps the part in the assembly slot. These two methods provide different processing environments. 4. When shaking, if the clamping part and the guide part collide with each other, the sound-absorbing layer will prevent noise from being generated when they come into contact, thereby improving the accuracy of shaking noise detection.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 9 This application will be described in further detail below.

[0032] This application discloses an assembly line for cooling fans.

[0033] An assembly line for cooling fans, reference Figure 1 As shown, the system includes a conveyor belt 1 and several assembly carriers 2. The conveyor belt 1 has an inlet and an outlet at its two ends. An assembly station 3 is provided within the conveying range from the inlet to the outlet. The assembly station 3 includes, at preset intervals, a dispensing station, a pressing station, a wear-resistant sheet assembly station, a buckle assembly station, a bearing assembly station, a fan blade assembly station, a cover assembly station, and an inspection station. Each station assembles its own parts. Each station can be staffed manually or equipped with a robotic arm 4 for parts assembly. Specifically, at the inlet end of the conveyor belt 1, one or more workers or... Robotic arm 4 places the basic components of the cooling fan—the base shell and the wires—on assembly carrier 2. Assembly carrier 2 transports the base shell and wires. When transporting to the dispensing station, a dispensing machine can be set up at the dispensing station to apply glue to the base shell. Then, it can be transported to the pressing station, which can be set up with a pressing machine. The main component to be assembled is the motor. The motor is pressed onto the dispensing point, and the wires are pressed together with the motor. Then, according to the assembly sequence of the components, the components are assembled sequentially through the wear-resistant sheet assembly station, the buckle assembly station, the bearing assembly station, the fan blade assembly station, and the top cover assembly station.

[0034] Assembly equipment is provided at the dispensing station, pressing station, wear-resistant sheet installation station, buckle installation station, bearing installation station, fan blade installation station, and cover installation station. Existing assembly equipment can meet the assembly requirements, and the style of the assembly device is irrelevant to the technical issues. Therefore, no restrictions are placed on the assembly equipment here.

[0035] After the cover is assembled at the top cover station, the overall cooling fan assembly is completed. After assembly, the conveyor belt 1 will transport the assembly carrier 2 to the inspection station. The inspection station mainly performs power-on testing, appearance inspection, and shaking and abnormal noise testing on the formed cooling fan on the assembly carrier 2 to ensure that the cooling fan can operate normally after assembly and meet the finished product standards. At the discharge end of the conveyor belt 1, a manual or robotic arm 4 can be set up to recycle the formed cooling fan.

[0036] Assembly carrier 2 is used to provide loading or support for parts during assembly. Using assembly carrier 2 for transportation and assembly can prevent parts from being scattered or inaccurately assembled, and prevent deviations in assembly position. At the same time, assembly carrier 2 can also support extended wires, avoiding excessively long wires from affecting the assembly.

[0037] A set of assembly carriers 2 are arranged at preset intervals on the conveyor belt 1. The conveyor belt 1 transports the assembly carriers 2 from the feeding end to the discharging end. During the transport process, they pass through each station in sequence, so that each part can be assembled on the assembly carrier 2. Several assembly carriers 2 move in sequence to form a stable assembly production line.

[0038] refer to Figure 2As shown, the assembly carrier 2 includes a carrier body 21 and an electrical cable carrier 22. The carrier body 21 has an assembly slot 211 for assembling parts. The carrier body 21 has a cylindrical slot structure. The assembly slot 211 provides a place for the parts. The assembly slot 211 can prevent the parts from falling off the carrier body 21, so as to ensure the accuracy of the assembly position during the conveying process. The outer bottom surface of the carrier body 21 can be provided with anti-slip rubber, or fixed suction cups, or electronic grippers, for fixing the carrier body 21. The type of conveyor belt 1 is determined and is not limited here.

[0039] The wire carrier 22 is arranged around the carrier body 21. The wire carrier 22 has a ring-shaped structure, and its inner diameter is greater than or equal to the outer diameter of the carrier body 21. It can be installed close to or tightly against the carrier body 21. The wire carrier 22 has an arc-shaped groove 221 for placing the power supply wire. The arc-shaped groove 221 fits the ring-shaped wall of the wire carrier 22 and is connected to the assembly groove 211. The wire extends from the assembly groove 211 into the arc-shaped groove 221 and is stored along the wall of the arc-shaped groove 221, so that the wire will not extend or swing out randomly, reducing the impact on the assembly. At the same time, the arrangement around the carrier body 21 can also reduce the area occupied by the wire loading.

[0040] The end of the arc-shaped groove 221 is provided with a slot 2231 for the power supply plug to extend out. The end of the wire is a plug, which is used for power connection. Therefore, after the wire is stored along the arc-shaped groove 221, the plug can extend out of the arc-shaped groove 221 through the slot 2231. After the plug extends out, it is convenient to connect to the power supply for power-on testing at the testing station.

[0041] Among them, the assembly groove 211 and the arc groove 221 are respectively provided with a through-hole for the power supply line to pass through, so that the wire can enter the arc groove 221 through the through-hole.

[0042] Positioning sensors, such as photoelectric sensors, laser displacement sensors, etc., are installed at the dispensing station, pressing station, wear-resistant sheet installation station, buckle installation station, bearing installation station, fan blade installation station, and inspection station to detect and position the moving position of the assembly carrier 2. The specific sensors used are determined according to the requirements and are not limited here.

[0043] In addition to the positioning sensors, the conveyor belt 1 uses intermittent conveying, which means that it stops after conveying a preset distance, and then continues after a preset time interval. This method allows each workstation set at a preset distance to be transported to the fixed-point moving assembly carrier 2, thereby improving the positional accuracy of the assembly carrier 2 at each workstation.

[0044] Specifically, the basic components of the cooling fan are placed on the assembly carrier 2. The assembly carrier 2 is transported from the feeding end to the discharging end by the conveyor belt 1. During the transport process, the components are assembled sequentially through the dispensing station, pressing station, wear-resistant sheet installation station, buckle installation station, bearing installation station, fan blade installation station, and top cover installation station. Finally, the cooling fan is inspected at the inspection station to determine whether it is qualified. During the transport process, the components are gradually formed in the assembly groove 211 of the carrier body 21. The carrier body 21 restricts the installation position of the components to avoid displacement of the loading position. The wires are simultaneously placed in the arc-shaped groove 221 of the wire carrier 22, so that the wires are wound along the surface of the carrier body 21 through the arc-shaped groove 221, so that the wires do not stick out or swing outside at will, thereby preventing the wires from affecting the loading of the components.

[0045] In some embodiments, reference Figure 3 and Figure 4 As shown, the carrier body 21 is also provided with a clamping mechanism 23. The clamping mechanism 23 provides fixation for the parts during assembly. When the parts move with the carrier body 21, such as to the pressing station or the fan blade assembly station, pressure needs to be applied to the parts to press or assemble them into the assembly slot 211. This can easily cause the parts to loosen or shift before assembly, affecting the machining accuracy. Therefore, the clamping mechanism 23 is provided in the carrier body 21 to clamp the parts and prevent them from shifting.

[0046] Furthermore, the clamping mechanism 23 includes a drive unit 231, a clamping unit 232, an elastic unit 233, and a guide unit 234; the carrier body 21 also has an installation cavity 212, and the installation cavity 212 is connected to the assembly groove 211. The drive unit 231 is installed in the installation cavity 212. The drive unit 231 can use two sets of clamping cylinders, which are arranged opposite to each other to provide a clamping effect.

[0047] The drive unit 231 extends to a drive end, and a guide part 234 is provided on the drive end. The guide part 234 can be a guide post. The clamping part 232 is sleeved with the guide part 234, and the clamping part 232 slides along the guide part 234. The guide post is used to provide guidance and pushing effect for the clamping part 232, that is, the clamping part 232 can move along the guide part 234. At the same time, under the push of the drive end of the drive unit 231, the guide part 234 can also push the drive unit 231 to move, thereby providing a rigid clamping effect for the part. The clamping part 232 is a clamping cylinder, and the outer diameter of the guide part 234 is larger than the opening of the clamping cylinder, so that the guide part 234 cannot be disengaged from the clamping cylinder.

[0048] When a drive unit 231 is provided, a battery pack for providing power can also be installed in the mounting cavity 212.

[0049] An elastic part 233 is also provided outside the drive unit 231. The elastic part 233 can be a spring, and several sets of springs can be provided to ensure the stability of its elastic force.

[0050] The elastic part 233 is connected to the clamping part 232 and provides elastic force to the clamping part 232 in the direction away from the driving part 231. The clamping part 232 extends into the assembly groove 211 to clamp the part.

[0051] Specifically, the clamping part 232 clamps the part, and there are two clamping methods. One is to use the elastic force of the elastic part 233 to move the clamping part 232 along the guide part 234 to flexibly clamp the part in the assembly groove 211. At this time, the end of the guide part 234 away from the drive part 231 does not contact the clamping part 232. The other is that the drive part 231 drives the guide part 234, so that the guide part 234 pushes the clamping part 232, so that the clamping part 232 is subjected to the pushing force and directly rigidly clamps the part in the assembly groove 211. These two methods provide different processing environments.

[0052] During the conveyor belt 1 transport, the parts are subjected to rigid clamping. When the cooling fan is assembled and moved to the inspection station, it can be switched to flexible clamping. The robotic arm 4 at the inspection station will clamp the assembly carrier 2 and perform shaking noise detection on the cooling fan. Therefore, when the cooling fan and the assembly carrier 2 are shaken at the same time, the clamping part 232 is affected by the elastic force of the elastic part 233, and the shaking amplitude will increase, making the shaking noise detection more accurate.

[0053] Furthermore, refer to Figure 4 As shown, both the clamping part 232 and the guide part 234 are provided with a sound-silencing layer 235. The sound-silencing layer 235 can be made of rubber or sponge, so that when the clamping part 232 and the guide part 234 collide with each other when shaken, the sound-silencing layer 235 will prevent noise from being generated when they come into contact, thereby improving the accuracy of shaking noise detection.

[0054] In some embodiments, reference Figure 5 As shown, the wire carrier 22 includes a fixing part 222, a pivoting part 26, and a wire clamping part 223; the fixing part 222 is fixedly connected around the carrier body 21, and the fixing part 222 is a fixing ring, which is installed along the outer wall of the carrier body 21. The pivoting part 26 is pivotally connected to the vehicle body 21. The pivoting part 26 may adopt two pivoting shafts. Two oppositely arranged pivoting holes or pivoting bearings may be opened on the outer wall of the vehicle body 21. The pivoting shafts are pivotally connected to the pivoting holes or pivoting bearings.

[0055] The cable clamping part 223 is installed on the pivot part 26. The cable clamping part 223 can be a semi-circular ring. After the semi-circular ring is connected to the pivot part 26, it can rotate through the pivot part 26. When it rotates towards the fixed part 222, it can abut against the fixed part 222 and use the fixed part 222 to provide load-bearing. The arc-shaped groove 221 is opened on the cable clamping part 223. When the cable clamping part 223 rotates away from the fixed part 222 through the pivot part 26, it can act as a handle and lift the vehicle body 21.

[0056] A push-pull block or push-pull ring can be provided at the end of the wire clamping part 223 away from the carrier body 21, so that the worker or robot arm 4 can hold the push-pull block or push-pull ring. By rotating the wire clamping part 223 along the pivot part 26, the carrier body 21 can be lifted up.

[0057] This method is mainly used in the inspection station. After the worker or robot 4 uses the wire clamping part 223 to lift the carrier body 21, it is convenient to perform finished product inspections such as shaking and abnormal noise detection, power supply detection and wind force detection. At the same time, the wire is located in the arc groove 221, so that when the carrier body 21 rotates along the pivot part 26, the wire clamping part 223 and the internal wire will not be affected. When assembling parts, the wire clamping part 223 is located on the fixed part 222 and will not interfere with or obstruct other assembly stations 3.

[0058] In some embodiments, reference Figure 5 and Figure 6 As shown, the wire clamping part 223 is also provided with a detection groove 2232, which is connected to the arc groove 221. The arc groove 221 is provided with a pull detection mechanism 24. The pull detection mechanism 24 is used to provide stability detection of the connection between the wire and the assembly part. It is mainly to prevent the connection between the wire and the part from being unstable and disconnected when pulled, so as to improve the pass rate of the connection between the wire and the part. The pull detection mechanism 24 will push the wire into the detection groove 2232 for pull detection.

[0059] The tensile testing mechanism 24 is mainly used for testing at the testing station. At other stations, the tensile testing mechanism 24 does not perform the testing process, and the wires are placed in a normal state.

[0060] Further reference Figure 6 As shown, the tension detection mechanism 24 includes a detection elasticity part 241, a pushing part 242, a limiting part 243, a locking part 244, and a guiding part 245. The guiding part 245 is embedded in the locking part 223 and communicates with the detection groove 2232. In other words, the detection groove 2232, the arc groove 221, and the guiding part 245 are all interconnected. The guiding part 245 can adopt a tubular structure, such as a guiding tube, but the top of the guiding tube has a guiding port, and both ends of the guiding tube are connecting ports.

[0061] The pushing part 242 extends through the conducting part 245 into the detection groove 2232. The pushing part 242 may include a pushing rod, a concave frame, and a limiting plate. The pushing rod extends through the conducting part 245 into the detection groove 2232. One end of the pushing rod is located inside the detection groove 2232, and the limiting plate is located at the end of the pushing rod outside the conducting part 245. The size of the limiting plate is larger than the diameter of the connecting port on the conducting tube, so that the pushing rod cannot be disengaged from the conducting part 245. The concave part of the concave frame fits the wire. The pushing rod drives the concave frame and the limiting plate to push the wire along the detection groove 2232 and the conducting part 245, so that the wire is inserted into the concave frame and is pulled and detected by force.

[0062] refer to Figure 6 and Figure 7 As shown, the limiting part 243 is installed on the top surface of the fixing part 222. The limiting part 243 can be a limiting frame. The bottom of the arc-shaped groove 221 is also provided with an insertion port (not shown in the figure). When the wire clamping part 223 abuts against the fixing part 222, that is, when the wire clamping part 223 is placed on the fixing part 222, the limiting part 243 extends into the arc-shaped groove 221 through the insertion port and blocks the detection groove 2232. When the detection groove 2232 is blocked, the concave frame cannot detach from the detection groove 2232, and thus the pull test cannot be performed.

[0063] The detection groove 2232 is provided with a snap-fit ​​groove 2451. The snap-fit ​​part 244 is sleeved on the push part 242 and snaps into the adjustment groove. The snap-fit ​​part 244 can be a snap-fit ​​ring. The snap-fit ​​ring is sleeved on the push rod of the push part 242 and is snapped into the snap-fit ​​groove 2451, so that the snap-fit ​​ring cannot move.

[0064] The pushing part 242 is provided with a pushing protrusion 2421. One end of the detection elastic part 241 is connected to the pushing protrusion 2421, and the other end is connected to the locking part 244. The detection elastic part 241 can be a detection spring. The elastic force of the detection spring is directed outward from the detection groove 2232. The detection elastic part 241 generates elastic force and applies it to the pushing protrusion 2421. The other end is applied to the locking part 244. Since the locking part 244 is fixed by the locking groove 2451, the elastic force is applied to the pushing part 242.

[0065] Specifically, when a pull test is required on the wire, the assembly carrier 2 moves to the testing station, and the robotic arm 4 at the testing station lifts the locking part 244. When the locking part 244 is lifted, the limiting part 243 disengages from the arc groove 221, so that the limiting part 243 no longer blocks the testing groove 2232. Without the blocking of the limiting part 243, the testing elastic part 241 applies an elastic force to the pushing part 242 in the direction of the arc groove 221 by pushing the protrusion 2421 and the locking part 244, thereby causing the pushing part 242 to move along the testing groove 2232 and the conducting part 245, pushing the wire, so that the wire is pulled by the elastic force. One end of the wire is fixed by the part, and the plug at the other end is locked by the bayonet 2231, thereby realizing the pull test of the wire.

[0066] Further, refer to Figure 8 and Figure 9 As shown, a number of snap-fit ​​slots 2451 are provided. The snap-fit ​​part 244 snaps into any snap-fit ​​slot 2451, and the bottom end of the snap-fit ​​part 244 is also provided with an adjustment port 2441. The snap-fit ​​part 244 can disengage from the snap-fit ​​slot 2451 through the adjustment port 2441. At the same time, depending on the snap-fit ​​part 244 being inserted into different adjustment ports 2441, the elastic force generated by the detection elastic part 241 is different, thereby adjusting the magnitude of the detection elastic force on different wire specifications in turn.

[0067] The tension testing mechanism 24 also provides that the position of the wire is stable during the testing of the cooling fan. The pushing part 242 is used to hold the wire in place, so that the wire will not deviate when the cooling fan is shaken.

[0068] A pressure sensor can be installed on the inner wall of the concave frame of the pushing part 242. When the wire enters the concave frame, the pressure sensor presses the wire tightly. The pressure sensor can detect the pressure on the wire, which can achieve two effects. First, it can detect the pressure on the wire to facilitate the adjustment of the position of the snap-fit ​​part 244, thereby adjusting the elasticity of the detection spring part 241. Second, when the wire is disconnected from the cooling fan and the pull test fails, the pressure sensor has no pressure data, so it can be determined that the cooling fan connected to the wire is a defective product.

[0069] When the wire clamping part 223 is lifted along the pivot part 26, it will pull a part of the wire. Therefore, a section of the wire will be left to extend out of the clamp 2231 to adapt to the rotation of the wire clamping part 223 without breaking the wire.

[0070] In some embodiments, reference Figure 5 As shown, the cable clamping part 223 is also provided with a wind force detection mechanism 25. When the cable clamping part 223 is provided with a wind force detection mechanism 25, the inner diameter of the cable clamping part 223 is larger than the outer diameter of the carrier body 21, so that there is enough space to place the wind force detection mechanism 25, and it will not be affected when it is lifted.

[0071] When the assembly carrier 2 moves to the testing station, the robotic arm 4 at the testing station lifts the wire clamping part 223 and the wind power testing mechanism 25 simultaneously along the pivot part 26, so that the wind power testing mechanism 25 is directly below the assembled cooling fan. At this time, the manual or robotic arm 4 provides the power plug to power the cooling fan, which can then blow on the wind power testing mechanism 25 to perform wind power testing.

[0072] During the wind test, the shaking and abnormal noise test is not conducted simultaneously. That is, the power cord plug is not powered during the shaking and abnormal noise test to avoid short circuits or leakage. The shaking and abnormal noise test can be carried out before the wind test.

[0073] Furthermore, the wind power detection mechanism 25 includes an impeller anemometer 251 and a noise sensor 252. The impeller anemometer 251 is installed on the wire clamping part 223, and the noise sensor is installed on either the impeller anemometer 251 or the wire clamping part 223. When the wire clamping part 223 is lifted, the impeller anemometer 251 faces the cooling fan, so that when the cooling fan is powered on, the impeller anemometer 251 can be used to detect the wind power. The noise sensor 252 has two main functions: first, to provide noise detection when detecting shaking noise, to determine whether there is any abnormal noise; second, to detect wind noise. When the cooling fan is powered on, the noise sensor 252 detects whether there is any wind noise, thus providing multiple data detection effects and improving the yield rate.

[0074] The inspection station is equipped with a controller, which receives the detection data from the impeller anemometer 251, noise sensor 252, and pressure sensor to determine whether there is an abnormality. If there is an abnormality, the controller will notify the back-end personnel or the robotic arm 4 to remove the defective products.

[0075] The impeller anemometer can be replaced with other wind power testing instruments as needed.
