Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figure 1-7 A ball joint automatic riveting device for an automobile wiper assembly mechanism includes a stand 1, a circulating workbench 2, a tool 3, a feeding mechanism 4, a vibration plate 5, a rotary riveter 6, a material taking mechanism 7 and a conveyor belt 8. The stand 1 includes a cabinet and a protective frame arranged above the cabinet. The stand 1 is used to provide an installation support platform for the equipment. The circulating workbench 2 is installed at the front end of the stand 1. Several toolings 3 are installed on the circulating workbench 2. A ball joint 9 and a crank 10 are placed on the tooling 3. The tooling 3 is used to position and support the ball joint 9 and the crank 10. A shock absorber is arranged at the right rear end of the circulating workbench 2. The shock absorbing platform 11 is installed on the platform 1 through a flexible support. A vibration disk 5 is installed above the shock absorbing platform 11.

The ball joint 9 to be processed is placed in the vibration disk 5. A guide hole is opened at the bottom of the vibration disk 5. Through the continuous vibration of the vibration disk 5, the ball joints 9 in the vibration disk 5 fall into the guide holes one by one. Since the head of the ball joint 9 is large and heavy, it tends to face downward when falling into the guide hole after vibration screening, thereby straightening the direction of the ball joint 9.

[0031] A feeding mechanism 4 is provided on the side below the vibration plate 5 close to the circulation workbench 2. The feeding mechanism 4 is installed on the stand 1. The upper end of the feeding mechanism 4 is connected to the vibration plate 5. The ball joint 9 falls into the feeding mechanism 4 through the vibration plate 5. The feeding mechanism 4 places the ball joints 9 one by one on the tooling 3. A rotary riveting machine 6 is provided above the left end of the circulation workbench 2. The rotary riveting machine 6 is installed on the stand 1. The rotary riveting machine 6 is used to rivet the ball joint 9 and the crank 10 on the tooling 3. A sensor is installed below the rotary riveting machine 6. When the sensor below the rotary riveting machine 6 senses that the ball joint 9 is placed on the tooling 3 below, the rotary riveting machine 6 will be moved to the workbench 3. When there is a crank 10, the rotary riveting machine 6 will automatically rivet the ball joint 9 and the crank 10. The conveyor belt 8 is installed on the stand 1 behind the circulating workbench 2. The right end of the conveyor belt 8 passes through the bottom of the shock-absorbing platform 11 and extends out of the right side of the stand 1. The left end of the conveyor belt 8 is installed with a material-collecting mechanism 7, which is installed on the stand 1 on the right side of the rotary riveting machine 6. The ball joint 9 and crank 10 riveted by the rotary riveting machine 6 are taken out from the tooling 3 through the material-collecting mechanism 7 and placed on the conveyor belt 8. Finally, the riveted ball joint 9 and crank 10 are transmitted to the right side of the stand 1 through the conveyor belt 8.

[0032] like Figure 2 As shown, a driving mechanism is arranged inside the circulation workbench 2, and the tooling 3 is driven by the driving mechanism to perform clockwise circulation motion on the circulation workbench 2. Pressing plates 22 are installed around and in the middle of the circulation workbench 2, and the pressing plates 22 press the edges of the tooling 3 to prevent the tooling 3 from shifting and falling off from the circulation workbench 2 during the circulation motion. Protective covers 21 are installed at the left and right ends of the circulation workbench 2, and the protective covers 21 are used to provide safety protection for the two ends of the circulation workbench 2.

The bushing 31 is used to place the ball joint 9. According to the size of the processed ball joint 9, the corresponding bushing 31 can be replaced. Three slots 32 are opened at the upper end of the tooling 3 in front of the bushing 31. The two ends of the slot 32 pass through the left and right ends of the tooling 3. The bottom of the slot 32 is opened with a screw hole. A U-shaped frame 33 is installed in the slot 32. The U-shaped frame 33 is fixed in the slot 32 by bolts. The two side columns of the U-shaped frame 33 are hollow structures. A positioning rod 34 is installed on 33, and the positioning rod 34 is inserted between the two columns of the U-shaped frame 33. The left and right ends of the positioning rod 34 are fixed to the U-shaped frame 33 by tightening the adjusting nuts. After loosening the adjusting nuts, the height of the positioning rod 34 can be adjusted up and down. When installing and using, the U-shaped frame 33 is installed in a suitable slot 32 according to the length that the crank 10 needs to support, and then the U-shaped frame 33 is fixed by bolts. According to the height that the crank 10 needs to support, the height of the positioning rod 34 is adjusted, thereby providing effective support for different cranks 10 and facilitating the subsequent riveting process.

[0034] like Figure 4 As shown, the feeding mechanism 4 includes a feed pipe 41, a first cylinder 45 and a second cylinder 46. A receiving port 43 is provided at the upper end of the feed pipe 41, and a feeding port 44 is provided at the lower end of the feed pipe 41. The receiving port 43, the feed pipe 41 and the feeding port 44 are connected vertically. The receiving port 43 is connected to the guide hole on the vibration plate 5. The ball joint 9 in the vibration plate 5 falls into the feed pipe 41 from the guide hole through the receiving port 43 in sequence. The lower end of the feeding port 44 corresponds to the bushing 31 on the tooling 3 therebelow. The ball joint 9 falls directly into the bushing 31 after falling from the feeding port 44.

[0035] like Figure 5 As shown, a mounting plate 42 is provided on the left side of the material distribution pipe 41, the first cylinder 45 and the second cylinder 46 are both mounted on the mounting plate 42, the first cylinder 45 is mounted above the second cylinder 46, a top head 47 is installed on the first cylinder 45, the front end of the top head 47 is inserted into the material distribution pipe 41, when the first cylinder 45 is in a retracted state, the front end of the top head 47 is in the inner wall of the material distribution pipe 41, and will not affect the falling of the ball joint 9, when the first cylinder 45 is in an extended state, the front end of the top head 47 is inserted into the material distribution pipe 41, which can block the ball joint 9 in the material distribution pipe 41 from falling, a partition plate 48 is installed on the second cylinder 46, the partition plate 48 is plugged into the material distribution pipe 41, a through hole is opened on the right side of the partition plate 48, the through hole on the partition plate 48 is the same size as the inner hole of the material distribution pipe 41, when the second cylinder 46 is in an extended state, the right end of the partition plate 48 passes through the material distribution pipe 41, and the left end of the partition plate 48 The ball joint 9 is blocked inside the material distribution pipe 41. When the second cylinder 46 is in a contracted state, the right end of the material separation plate 48 is retracted into the material distribution pipe 41, and the through hole on the material separation plate 48 coincides with the inner hole of the material distribution pipe 41. The ball joint 9 falls through the through hole on the material separation plate 48. A sensor is provided at the lower end of the feeding port 44. The tooling 3 intermittently moves on the circulation workbench 2 to the bottom of the feeding port 44. When the sensor below the feeding port 44 senses that there is no ball joint 9 on the tooling 3, The first cylinder 45 drives the ejector head 47 to retract, and when the ball joint 9 falls onto the separator plate 48, the first cylinder 45 drives the ejector head 47 to extend, to support the second ball joint 9 on the separator plate 48, to prevent the ball joint 9 from falling continuously, and the second cylinder 46 drives the separator plate 48 to retract, so that the first ball joint 9 on the separator plate 48 falls into the bushing 31 on the tooling 3, and the second cylinder 46 extends and the first cylinder 45 contracts, and this cycle completes the automatic feeding to the tooling 3.

[0036] like Figure 6As shown, the material picking mechanism 7 includes a cross arm 71, a third cylinder 72 and a fourth cylinder 73. The cross arm 71 is fixedly mounted on the stand 1 through a bracket. The third cylinder 72 can be slidably mounted on the cross arm 71. The fourth cylinder 73 is installed in parallel with the cross arm 71. The fourth cylinder 73 is connected to the cylinder wall of the third cylinder 72. The third cylinder 72 is driven by the fourth cylinder 73 to slide back and forth on the cross arm 71. An electromagnet 74 is installed at the lower end of the third cylinder 72. When the electromagnet 74 is energized, it can absorb the crank 10 and the ball joint 9 on the tooling 3. A sleeve 75 is installed under the electromagnet 74. The sleeve 75 can buffer the impact when the electromagnet 74 absorbs the crank 10 and the ball joint 9, thereby reducing noise and protecting the electromagnet 74 and the crank 10.

[0037] When the fourth cylinder 73 is in the extended state, it drives the third cylinder 72 and the electromagnet 74 to be directly above the tooling 3. When the fourth cylinder 73 is in the retracted state, it drives the third cylinder 72 and the electromagnet 74 to be above the left end of the conveyor belt 8. When taking materials, the third cylinder 72 drives the electromagnet 74 to extend above the tooling 3, and the electromagnet 74 is energized to suck the riveted crank 10 and the ball joint 9 onto the electromagnet 74. Then the third cylinder 72 drives the electromagnet 74, the crank 10 and the ball joint 9 to retract, and then the fourth cylinder 73 is in the retracted state. The cylinder 73 retracts, driving the third cylinder 72 and the electromagnet 74 to the top of the conveyor belt 8, and then the electromagnet 74 is powered off. The riveted crank 10 and ball joint 9 fall onto the conveyor belt 8, and are transferred by the conveyor belt 8 to the material cart next to the stand 1. Finally, the fourth cylinder 73 extends out, driving the third cylinder 72 and the electromagnet 74 back to the top of the tooling 3. This cycle completes the automatic material removal. Guardrails 81 are provided at the front and rear ends of the conveyor belt 8 to prevent the crank 10 and ball joint 9 on the conveyor belt 8 from slipping.

[0038] During the use of the present invention: a worker stands at the front end of the equipment, and the ball joint 9 falls into the feeding mechanism 4 in sequence through the vibrating plate 5, and the feeding mechanism 4 places the ball joint 9 one by one on the empty tooling 3; the tooling 3 moves clockwise under the drive of the circulating workbench 2, and when the tooling 3 with the ball joint 9 placed thereon moves with the circulating workbench 2 to the front of the worker, the worker places the crank 10 on the ball joint 9; when the tooling 3 with the ball joint 9 and the crank 10 placed thereon moves to the riveting position of the rotary riveting machine 6, the sensor under the rotary riveting machine 6 senses, and the rotary riveting machine 6 automatically rivets the crank 10 and the ball joint 9; when the riveted crank 10 and ball joint 9 move to the material taking position, the material taking mechanism 7 automatically takes the material and transmits the riveted crank 10 and ball joint 9 out through the conveyor belt 8; the empty tooling 3 with the material taken out moves to the bottom of the feeding mechanism 4, and the feeding mechanism 4 places the ball joint 9, and the cycle is repeated to quickly complete the riveting work of the crank 10 and the ball joint 9.
