Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figure 1 and Figure 2As shown, a preferred embodiment of the airtightness detection device for an assembly line of this utility model includes a frame 1, an airtightness detection mechanism 2, a defective product gripping mechanism 3, and a waste collection box 4. The airtightness detection mechanism 2 is mounted on the frame 1 and is used to grip the drive shaft 6 on the conveying mechanism 5 and perform airtightness detection on it. The waste collection box 4 is placed on the frame 1 and is positioned on the frame 1 for easy handling. The waste collection box 4 is used to collect defective drive shafts 6. The defective product gripping mechanism 3 is mounted on the frame 1 and is used to grip the defective drive shaft 6 on the conveying mechanism 5 and place it into the waste collection box 4.

[0027] The airtightness detection mechanism 2 includes airtight grippers 21, an airtight actuator 22, an airtight lifter 23, a sealing assembly 24, an air supply assembly 25, and a flow detection device 26. The airtight grippers 21 are mounted on the airtight actuator 22. There are two airtight grippers 21, and the pawls are used to grip the drive shaft 6. The airtight actuator 22 drives the two airtight grippers 21 to move towards or away from each other, thereby gripping or releasing the drive shaft 6. The airtight actuator 22 typically uses a cylinder for the airtight grippers 21; using conventional components reduces the development of parts and lowers R&D costs. The airtight actuator 22 is mounted on the airtight lifter 23. The airtight lifter 23 drives the airtight actuator 22 to rise and fall, which in turn drives the airtight grippers 21 to rise and fall, ultimately driving the drive shaft 6 to rise and fall. The airtight lifter 23 typically uses a cylinder; using common components reduces costs. The sealing assembly 24 is used to seal one end of the drive shaft 6. The sealing assembly 24 is mounted on the frame 1 and located on one side of the conveying mechanism 5. The air supply assembly 25 is used to seal the other end of the drive shaft and supply gas into the shaft hole of the drive shaft 6. The air supply assembly 25 is mounted on the frame 1 and located on the other side of the conveying mechanism 5, i.e., opposite to the sealing assembly 24. The air supply assembly 25 is connected to an external air source through an air pipe to facilitate the supply of gas into the shaft hole of the drive shaft 6. The flow detection device 26 is mounted on the air pipe and is used to detect the gas flow rate passing through that location. The flow detection device 26 is typically a flow meter. The difference between the flow rate detected by the flow detection device 26 and the flow rate of the standard component is used to determine whether the gas is qualified. Too much or too little flow rate is unqualified. Only flow rate within the allowable error range is considered qualified.

[0028] like Figure 3 As shown, the airtight gripper 21 is provided with a positioning groove 211. The positioning groove 211 is V-shaped. Of course, in other embodiments, the positioning groove 211 can also be C-shaped. The positioning groove 211 is used to position the drive shaft 6 and prevent the drive shaft 6 from falling off the airtight gripper 21.

[0029] like Figure 4 and Figure 5 As shown, the sealing assembly 24 includes a first plug 241, a first mounting base 242, a first slide block 243, a first slide rail 244, a first connecting plate 245, a first sealing driver 246, and a first base 247. The first plug 241 is detachably mounted on the first mounting base 242. The first plug 241 is used to seal one end of the shaft hole of the drive shaft 6. The first plug 241 can seal the shaft hole by fitting against one end of the drive shaft 6. To ensure complete sealing of the shaft hole, the diameter of the plug is usually set to be larger than the diameter of the shaft hole. The first mounting base 242 is fixed on the first connecting plate 245, and the first connecting plate 245 is mounted on the first slide block 243, so that the first mounting base 242 is indirectly mounted on the first slide block 243. In other embodiments, the first mounting base 242 can also be directly mounted on the first slide block 243, while the first connecting plate 245 is fixed on the first mounting base 242. The first slide block 243 is slidably mounted on the first slide rail 244 and can move along the first slide rail 244. The first slide rail 244 is mounted on the first base 247, and the first sealing actuator 246 is mounted on the first base 247. The output end of the first sealing actuator 246 is connected to the first connecting plate 245. The first sealing actuator 246 is used to drive the first connecting plate 245 to move, thereby driving the first mounting base 242 to move, thus driving the first plug 241 to move. For better sealing effect, a deformable first sealing plug 248 is installed on the first plug 241. The deformation of the first sealing plug 248 makes it fit more tightly with the end face of the drive shaft 6. The first sealing plug 248 is usually made of rubber or silicone.

[0030] The first mounting base 242 is provided with a first mounting hole 2421, and the first plug 241 is inserted into the first mounting hole 2421. The first mounting base 242 is provided with a first locking hole 2422, which communicates with the first mounting hole 2421. Generally, the first locking hole 2422 and the first mounting hole 2421 are perpendicular. A first locking member 249 is screwed into the first locking hole 2422. When the first locking member 249 is rotated, it can contact or move away from the first plug 241, thereby locking or unlocking the first plug 241. The first locking member 249 is usually a bolt, using conventional components to reduce costs. By unlocking the first plug 241, its position can be moved to accommodate drive shafts 6 of different lengths and various specifications.

[0031] like Figure 6 and Figure 7 As shown, the air supply assembly 25 includes a second plug 251, a second mounting base 252, a second slide block 253, a second slide rail 254, a second connecting plate 255, a second sealing actuator 256, and a second base 257. The second plug 251 has an air supply hole, and the air pipe communicates with the air supply hole. Typically, a connector is installed inside the air supply hole, and the air pipe is fixed to the connector to achieve communication between the two. The air supply hole is aligned with the shaft hole of the drive shaft 6 to ensure stable gas delivery into the shaft hole. The second plug 251 is detachably mounted on the second mounting base 252. The second plug 251 is used to seal one end of the shaft hole of the drive shaft 6. The second plug 251 is placed against one end of the drive shaft 6 to seal its shaft hole. To ensure complete sealing of the shaft hole, the diameter of the plug is typically set to be larger than the diameter of the shaft hole. The second mounting base 252 is fixed on the second connecting plate 255, and the second connecting plate 255 is mounted on the second slide block 253, so that the second mounting base 252 is indirectly mounted on the second slide block 253. In other embodiments, the second mounting base 252 can also be directly mounted on the second slide block 253, while the second connecting plate 255 is fixed on the second mounting base 252. The second slide block 253 is slidably disposed on the second slide rail 254, and the second slide block 253 can move along the second slide rail 254. The second slide rail 254 is mounted on the second base 257, and the second sealing actuator 256 is mounted on the second base 257. The output end of the second sealing actuator 256 is connected to the second connecting plate 255, and the second sealing actuator 256 is used to drive the second connecting plate 255 to move, thereby driving the second mounting base 252 to move, thereby driving the second plug 251 to move. For better sealing, a deformable second sealing plug 258 is installed on the second plug 251. The deformation of the second sealing plug 258 makes it fit more tightly with the end face of the drive shaft 6. The second sealing plug 258 is usually made of rubber or silicone.

[0032] The second mounting base 252 is provided with a second mounting hole 2521, and the second plug 251 is inserted into the second mounting hole 2521. The second mounting base 252 is provided with a second locking hole 2522, which communicates with the second mounting hole 2521. Generally, the second locking hole 2522 is perpendicular to the second mounting hole 2521. A second locking member 259 is screwed into the second locking hole 2522. When the second locking member 259 is rotated, it can abut against or move away from the second plug 251, thereby locking or unlocking the second plug 251. The second locking member 259 is usually a bolt, using conventional components to reduce costs. By unlocking the second plug 251, its position can be moved, allowing it to adapt to drive shafts 6 of different lengths and various specifications.

[0033] Combination Figure 1 , Figure 2 and Figure 8Referring to the description, the defective product gripping mechanism 3 includes defective product gripping jaws 31, a defective product driver 32, a defective product lifter 33, a first gripping connecting plate 34, a second gripping connecting plate 35, a movable slide block 36, a movable slide rail 37, and a movable driver 38. The defective product gripping jaws 31 are mounted on the defective product driver 32. There are two defective product gripping jaws 31. The defective product driver 32 drives the two defective product gripping jaws 31 to move towards or away from each other, thereby gripping or releasing the drive shaft 6. The defective product driver 32 is mounted on the defective product lifter 33. The defective product lifter 33 drives the defective product driver 32 to rise and fall, thereby driving the defective product gripping jaws 31 to rise and fall, and thus driving the drive shaft 6 located on the defective product gripping jaws 31. The defective product lifter 33 is mounted on the first gripping connecting plate 34, which is mounted on the movable slide 36. The first slide 243 is slidably mounted on the movable slide rail 37. The second gripping connecting plate 35 is mounted on the first gripping connecting plate, and the output end of the movable drive is connected to the second gripping connecting plate 35. The movable driver 38 is mounted on the frame 1 and is used to drive the second gripping connecting plate 35 to move. The defective product driver 32 and the defective product lifter 33 are cylinders, and the defective product driver 32 is a gripper cylinder. The defective product gripper 31 is typically positioned directly above the conveying mechanism 5 to facilitate faster gripping of the defective drive shaft 6. When grabbing is required, the defective product lifter 33 drives the defective product driver 32 and the defective product gripper 31 to move downwards. After moving to the position of the drive shaft 6, the defective product driver 32 drives the defective product gripper 31 to move towards each other to grab the drive shaft 6. Then, the defective product lifter 33 resets, causing the defective product driver 32 and the defective product gripper 31 to reset and move above the conveyor mechanism 5. Then, the motion driver 38 drives the second gripping connecting plate 35 to move, causing the defective product gripper 31 to move along the moving slide rail 37. After moving above the waste collection box 4, the defective product driver 32 drives the defective product gripper 31 to move in the opposite direction to release the drive shaft 6. The drive shaft 6 falls into the waste collection box 4. Finally, the motion driver 38 resets, causing the defective product gripper 31 to reset, ready for the next use. When the drive shaft 6 released by the defective product gripper 31 falls to a relatively high height in the waste collection box 4, the lifter driver can be used to lower it first before releasing the drive shaft 6.

[0034] In use, firstly, the airtight lifting device 23 moves the airtight gripper 21 and the airtight defective product driver 32 downwards, moving the airtight gripper 21 to both sides of the transmission shaft 6 and then stopping its downward movement. Then, the airtight defective product driver 32 drives the airtight gripper 21 to clamp the transmission shaft 6. Then, the airtight lifting device 23 resets and moves the transmission shaft 6 upwards. After that, the first and second plugs simultaneously drive the corresponding first plug 241 and second plug 251 to fit against both ends of the transmission shaft 6, thus sealing the shaft hole. Then, the gas is sent into the shaft hole and the flow detection device 26 detects the total flow rate. The total flow rate is compared with the gas flow rate weight required for the standard part to determine whether it is qualified. After the inspection is completed, the first and second plugs drive the first plug 241 and the second plug 251 to reset respectively. Then, the airtight lifter 23 drives the airtight gripper 21 and the drive shaft 6 to move down. After moving down to the predetermined position, the airtight defective product driver 32 drives the airtight gripper 21 to release the drive shaft 6 and release the drive shaft 6 onto the conveying mechanism 5. After that, the airtight lifter 23 resets and drives the airtight gripper 21 to reset. At the same time, the transmission mechanism conveys the drive shaft 6 that needs to be inspected in the next stage to the airtight gripper 21, and moves the inspected drive shaft 6 to the next station.

[0035] The transmission shaft 6 on the conveying mechanism 5 can be picked up by the cooperation of the airtight lifting device 23, the airtight gripper 21 and the airtight defective product driver 32. Then, the transmission shaft 6 is tested by the sealing mechanism and the air supply mechanism. The quality is judged according to the flow rate. The transmission shaft 6 can be moved manually without the need for manual handling, which saves time and efficiency.

[0036] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, whether directly or indirectly applied to other related technical fields, shall also be within the patent protection scope of this utility model.
