Description

Technical Field

[0001] This utility model relates to the field of air conditioning assembly technology, and in particular to a locking module and locking device. Background Technology

[0002] In the assembly process of air conditioner outdoor units, the tightening of the fan blade nuts is a critical step. The quality of this tightening directly affects the stability of the fan blade operation and the overall reliability of the unit, thus impacting its heat dissipation efficiency and long-term reliability. Currently, the industry commonly uses servo motors or intelligent electric screwdrivers as the tightening mechanism for the fan blade nuts. Their control methods are mostly based on a current loop feedback mechanism, which indirectly reflects the applied tightening torque by monitoring changes in the motor's current during operation and stops the tightening action when a preset torque value is reached.

[0003] Intelligent electric screwdrivers typically integrate various sensors, such as torque and angle sensors, to collect torque and rotation angle data in real time during the tightening process. The control system dynamically adjusts the motor state based on this feedback information, achieving closed-loop control and ensuring the accuracy and consistency of the tightening process. However, this torque control method based on current feedback has certain limitations. Because the relationship between motor current and output torque is not always strictly linear, especially under conditions of significant load changes, the current signal is prone to fluctuations, making it difficult to accurately determine the actual tightening torque.

[0004] In actual fastening operations, when the fastening torque approaches the rated value, the follow-up phenomenon of the fan motor will seriously interfere with the fastening process. This passive rotation not only reduces the effective fastening torque, but also further exacerbates the instability of current detection due to factors such as the difference in damping characteristics of different models of fan motors and changes in the assembly environment. As a result, the fastening method based on current loop control cannot guarantee stable fastening quality, and defects such as under-tightening or uneven fastening force are prone to occur, which seriously affects the product assembly qualification rate.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0053] The following is combined Figures 1-7 This invention describes the locking module and locking device.

[0054] An embodiment of the first aspect of this utility model provides a locking module, such as... Figures 2 to 6 As shown, the lock attachment module includes a drive assembly 110, a lock attachment 130, and a locking assembly 120 disposed between the drive assembly 110 and the lock attachment 130.

[0055] The locking component 120 includes a first connecting component 121 and a second connecting component 122. The first connecting component 121 is located at the output of the drive component 110, and a first positioning part 1213 is provided on the side of the first connecting component 121 away from the drive component 110. The second connecting component 122 is located on the side of the first connecting component 121 away from the drive component 110, and a second positioning part 1223 is provided that cooperates with the first positioning part 1213. The lock accessory 130 is connected to the side of the second connecting component 122 away from the first connecting component 121.

[0056] The first connecting member 121 is adapted to switch between a first position and a second position. In the first position, the first positioning part 1213 engages with the second positioning part 1223 to lock the first connecting member 121 with the second connecting member 122. In the second position, the first positioning part 1213 moves out of the second positioning part 1223 to release the lock between the first connecting member 121 and the second connecting member 122.

[0057] It is understood that a locking component 120 is added between the drive component 110 and the lock accessory 130. The locking component 120 is used to lock and decouple the drive component 110 and the lock accessory 130. Specifically, the locking component 120 includes a cooperating first connecting part 121 and a second connecting part 122. The first connecting part 121 is installed at the output end of the drive component 110, and the second connecting part 122 is installed at the lock accessory 130. The first connecting part 121 is provided with a first positioning part 1213, and the second connecting part 122 is provided with a second positioning part 1223. In the initial state, the first positioning part 1213 and the second positioning part 1223 are positioned and engaged so that the first connecting part 1213 is engaged with the second positioning part 1223. The first connecting member 121 and the second connecting member 122 are locked together, thereby locking the drive assembly 110 and the locking accessory 130. At this time, the drive assembly 110 drives the locking accessory 130 to perform the locking operation on the workpiece being locked on the locking accessory 130. When the workpiece being locked is locked to the rated torque, the first connecting member 121 and the second connecting member 122 move relative to each other, so that the first positioning part 1213 moves out of the second positioning part 1223, releasing the lock between the first connecting member 121 and the second connecting member 122. This automatically decouples the drive assembly 110 and the locking accessory 130, thereby achieving stable locking and rapid release of the locking state and improving the consistency and reliability of the locking quality.

[0058] It should be noted that the locking accessory 130 can be a screwdriver bit, which is used to pick up the nut to achieve the locking of the nut; of course, the locking accessory 130 can also be used to lock bolts.

[0059] The locking module provided in this embodiment of the utility model provides a locking component 120 between the drive component 110 and the locking attachment 130. By cooperating and separating the positioning part between the first connecting part 121 and the second connecting part 122 of the locking component 120, stable locking and rapid release of the locking state are achieved, thereby improving the consistency and reliability of the locking process, increasing the product assembly qualification rate, and thus improving the overall production efficiency and product quality.

[0060] In one embodiment of this utility model, the locking module further includes a controller (not shown in the figure), such as Figure 4 As shown, the drive assembly 110 is connected to the first terminal 140, the lock accessory 130 is connected to the second terminal 150, and the controller is electrically connected to the first terminal 140 and the second terminal 150.

[0061] Specifically, in the first position, the first connecting component 121 is connected to the first terminal 140 and the second terminal 150; in the second position, the first connecting component 121 is disconnected from the first terminal 140 and the second terminal 150, and the controller sends a stop command to the drive assembly 110.

[0062] Understandably, in the initial state, the first connecting member 121 is in the first position, and the first positioning part 1213 and the second positioning part 1223 are positioned and engaged, locking the first connecting member 121 and the second connecting member 122. At this time, the first terminal 140 and the second terminal 150 are connected, and the drive assembly 110 drives the locking accessory 130, thereby driving the workpiece to be locked on the locking accessory 130 to perform the locking operation. When the workpiece is locked to the rated torque, relative movement occurs between the first connecting member 121 and the second connecting member 122, so that the first positioning part 1213 moves out of the second positioning part. In section 1223, the drive assembly 110 and the locking attachment 130 are automatically decoupled. At this time, the first connecting part 121 is in the second position, and the first terminal 140 and the second terminal 150 are disconnected. The controller sends a stop command to the drive assembly 110, and the drive assembly 110 stops by holding the brake based on the stop command. In this way, when the locked workpiece reaches the rated torque, the drive assembly 110 (power part) and the locking attachment 130 (rotating part) achieve instantaneous disengagement, effectively preventing damage to the locked workpiece caused by excessive torque, thereby further improving the assembly quality and product consistency.

[0063] It should be noted that when the locking module is normally locking the workpiece, the locking module maintains a large torque. At this time, the first terminal 140 and the second terminal 150 are connected to form a normally closed circuit, which is connected to the input terminal of the controller. When the workpiece is locked to the rated torque, the first terminal 140 and the second terminal 150 are disconnected to open the normally closed circuit. When the normally closed circuit is open, the controller sends a stop command to the drive assembly 110 to control the drive assembly 110 to stop the brake.

[0064] In one embodiment of this utility model, such as Figures 5 to 7 As shown, the first connecting component 121 includes a connecting bushing 1211 and a positioning member 1212. The output of the drive assembly 110 is provided with an output shaft. The connecting bushing 1211 is sleeved on the output shaft of the drive assembly 110. The connecting bushing 1211 is provided with a mounting hole. The positioning member 1212 is provided in the mounting hole, and the positioning member 1212 has a first positioning part 1213 extending out of the connecting bushing 1211.

[0065] Optionally, the second connecting component 122 includes a connecting body 1221 and a connecting member 1222. The connecting body 1221 is disposed on the lock accessory 130 and has a connecting hole 12211. The connecting member 1222 is disposed in the connecting hole 12211. One end of the connecting member 1222 is connected to the lock accessory 130, and the other end of the connecting member 1222 has a second positioning part 1223. It should be noted that the number of mounting holes and connecting holes 12211 are equal and their positions correspond one-to-one; correspondingly, the number of positioning members 1212 and connecting members 1222 are equal and their positions correspond one-to-one.

[0066] Among them, the connecting body 1221 is an insulating component; the first connecting component 121 is in a first position, the first positioning part 1213 of the positioning component 1212 and the second positioning part 1223 of the connecting component 1222 are positioned and engaged, and the first positioning part 1213 and the second positioning part 1223 abut against each other. At this time, the first terminal 140 is connected to the second terminal 150 through the driving assembly 110, the first connecting component 121, the connecting component 1222, and the locking accessory 130.

[0067] The first connecting component 121 is in the second position, and the first positioning part 1213 of the positioning member 1212 abuts against the connecting body 1221. The connecting body 1221 is made of insulating material. At this time, the first connecting component 121 and the locking accessory 130 are insulated and isolated so that the first terminal 140 and the second terminal 150 are disconnected.

[0068] In one embodiment of the present invention, the first positioning part 1213 is a plurality of parts arranged circumferentially; correspondingly, the second positioning part 1223 is also a plurality of parts arranged circumferentially.

[0069] Furthermore, multiple first positioning parts 1213 are evenly distributed along the circumference; correspondingly, multiple second positioning parts 1223 are evenly distributed along the circumference.

[0070] For example, the connecting bushing 1211 is provided with multiple mounting holes, and each mounting hole is provided with a positioning element 1212; the connecting body 1221 is provided with multiple connecting holes 12211, and each connecting hole 12211 is provided with a connecting element 1222; wherein, the first positioning part 1213 of the positioning element 1212 and the second positioning part 1223 of the connecting element 1222 can be spherical fit.

[0071] In this embodiment, the positioning member 1212 is a ball head bolt, and the ball head of the ball head bolt extends out of the connecting bushing 1211; the connecting hole 12211 is a stepped hole, the connecting member 1222 is a bolt, the nut of the bolt is set at the large end of the stepped hole, and the nut is provided with a spherical hole that mates with the ball head, and the bolt shank is set at the small end of the stepped hole and connected to the locking accessory 130.

[0072] In one embodiment of this utility model, such as Figure 4 and Figure 6 As shown, it also includes a mounting bracket 160, a locking accessory 130 rotatably mounted on the mounting bracket 160, and a drive assembly 110 mounted on the mounting bracket 160 via an insulating bracket 170.

[0073] It is understandable that an insulating bracket 170 is provided between the drive assembly 110 and the mounting bracket 160 to form electrical isolation between the drive assembly 110 and the locking accessory 130, thereby preventing current conduction between them through the mounting structure. Thus, the electrical connection between the drive assembly 110 and the locking accessory 130 can only be achieved through the conduction of the locking assembly 120, ensuring the uniqueness of the current conduction path and improving the accuracy of electrical control. It should be noted that the locking assembly 120 is activated when the first connecting member 121 is in the first position, and the first positioning part 1213 and the second positioning part 1223 are positioned and engaged in contact; the locking assembly 120 is deactivated when the first connecting member 121 is in the second position, the first positioning part 1213 moves out of the second positioning part 1223, and the first positioning part 1213 abuts against the insulated connecting body 1221.

[0074] In one embodiment of this utility model, such as Figure 6 As shown, the lock accessory 130 is provided with a limiting part 131, and the mounting bracket 160 is provided with a positioning part; in the first position, the limiting part 131 is away from the positioning part; in the second position, the limiting part 131 abuts against the positioning part.

[0075] It is understood that the movement of the first connecting component 121 between the first position and the second position is achieved by rotating the first connecting component 121. During the rotation of the first connecting component 121, the second connecting component 122 is driven to move axially, thereby driving the lock accessory 130 to move axially. In the first position, the first positioning part 1213 is engaged with the second positioning part 1223, and the limiting part 131 is away from the positioning part. In the second position, the first positioning part 1213 moves out of the second positioning part 1223, and the second connecting component 122 and the lock accessory 130 move synchronously away from the first connecting component 121 and abut against the positioning part through the limiting part 131 to limit the movement position of the lock accessory 130. At this time, the first positioning part 1213 abuts against the end face of the connecting body 1221.

[0076] In this embodiment, the lock attachment 130 is mounted on the mounting bracket 160 via a bearing. One end of the lock attachment 130 connected to the second connecting component 122 is provided with an annular protrusion. This annular protrusion can serve as a limiting part 131, and the bearing can serve as a positioning part. The annular protrusion abuts against the bearing end face to limit the position of the lock attachment 130, thereby limiting the position between the first connecting component 121 and the first connecting component 122.

[0077] A second aspect of this utility model provides a locking device, which includes the locking module 100 provided in any of the above embodiments.

[0078] It is understood that the locking device includes the locking module 100 provided in any of the above embodiments. Through the coordinated cooperation between the drive component 110, the locking component 120 and the locking accessory 130, precise control of the locking process is achieved, ensuring the consistency and reliability of the locking quality.

[0079] For example, the locking device is used to lock the fixing nut of the air conditioner outdoor unit fan blade; wherein, the air conditioner outdoor unit includes a housing and a fan blade motor disposed in the housing, the fan blade is mounted on the output shaft of the fan blade motor, and the output shaft can be a screw that mates with the nut; the locking attachment 130 picks up the nut and operates through the locking module 100 to lock the nut to the output shaft of the fan blade motor.

[0080] Understandably, during the locking process of the locking module 100 to the nut, when the nut (locking torque) reaches the rated torque, the drive component 110 (power part) and the locking accessory 130 achieve instantaneous disengagement. After successful disengagement, the controller controls the drive component 110 to brake. After the locking is completed, the locking accessory 130 brakes the fan motor in the opposite direction, causing the fan motor to stop rotating.

[0081] Optionally, the locking module 100 or locking device can be installed on the robot or XYZ module to pick up, move, and lock the nut according to the rated torque.

[0082] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the locking device also includes a floating mechanism 200, and the locking module 100 is disposed on the floating mechanism 200.

[0083] It is understandable that the locking module 100 is mounted on the floating mechanism 200, enabling the locking module 100 to adaptively adjust according to the positional changes of the locked workpiece during the locking process; the floating mechanism 200 effectively compensates for workpiece assembly errors or positional deviations, improves the adaptability of the locking process, thereby ensuring the stability and reliability of the locking action, and further improving the product assembly accuracy and locking quality.

[0084] In one embodiment of this utility model, such as Figure 2 As shown, the floating mechanism 200 includes a floating support 210, a floating body 220, and an elastic element 230. The floating body 220 is slidably disposed on the floating support 210 and can move freely within a certain range in a set direction. The elastic element 230 is disposed between the floating support 210 and the floating body 220. The elastic element 230 is used to provide the floating body 220 with an elastic restoring force so that it automatically returns to its initial position after the locking action is completed. The mounting bracket 160 of the locking module 100 is fixedly disposed on the floating support 210, thereby driving the entire locking module 100 to move together with the floating body 220 to adapt to small deviations in the workpiece position, realize flexible locking, and improve the stability and assembly accuracy of the locking process.

[0085] Optionally, the floating support 210 is provided with a slide rail 211, and the floating body 220 is mounted on the slide rail 211.

[0086] Furthermore, the floating mechanism 200 also includes a guide member 260 parallel to the slide rail 211. One end of the guide member 260 is disposed on the floating support 210, and the floating body 220 is slidably disposed on the other end of the guide member 260. An elastic member 230 is sleeved on the guide member 260 and confined between the floating body 220 and the floating support 210. It should be noted that a limit member is provided at the other end of the guide member 260 to prevent the floating body 220 from detaching from the guide member 260.

[0087] In this embodiment, the guide member 260 is a guide rod, and the elastic member 230 is a spring. There are two guide rods arranged in parallel, and the two guide rods are located on both sides of the slide rail 211. Each guide rod is equipped with a spring. The guide rod is used to provide guidance for the spring, and the spring provides floating force to the floating body 220 to ensure the flexibility of the locking process.

[0088] In one embodiment of this utility model, the floating bracket 210 is provided with a photoelectric switch 250.

[0089] It is understandable that the photoelectric switch 250 is used to detect the position change of the floating body 220 or the displacement state of the locking module 100 in real time. The photoelectric switch 250 can sense the movement of the floating body 220 during the locking process and feed the signal back to the control system to realize the control and judgment of the locking action, such as judging whether it has contacted the workpiece or whether the locking has been completed.

[0090] In one embodiment of the present invention, the floating support 210 is provided with a buoyancy detection element 240; wherein, the buoyancy detection element 240 includes, but is not limited to, a point laser sensor.

[0091] Understandably, the floating height detection component 240 of the floating bracket 210 is used to monitor in real time the displacement of the floating body 220 in a set direction during the locking process, i.e., the change in floating height. By detecting the floating height, the contact state between the locking module 100 and the workpiece, the locking depth, and the application of the locking force can be accurately determined, thereby achieving precise control of the locking process. This helps to improve the adaptability of the locking device to different assembly conditions, ensure the stability and consistency of the locking action, and further improve the reliability of product assembly accuracy and locking quality.

[0092] In one embodiment of this utility model, the floating support 210 is provided with a negative pressure detection element.
