[0062] Below, embodiments of the present invention are described in detail with reference to the accompanying drawings. To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0063] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.

[0064] like Figure 1 As shown, the automatic production system of the automotive parts 1000 in this embodiment is mainly composed of a bushing processing unit 10, an upper plate conveying unit 20, a lower plate conveying unit 30, a bolt conveying unit 40, a riveting unit 50, a pressing unit 60, a finished product inspection unit 70, a finished product coding unit 80, a first conveying unit 90a, a second conveying unit 90b and a third conveying unit 90c.

[0065] Combine Figure 2-Figure 4 As shown, the automobile component 1000 targeted in this embodiment is an automobile chassis component, which is mainly composed of an upper plate 1001, a lower plate 1002, a bushing 1003 arranged therebetween, and bolts 1004 pressed between the upper plate 1001 and the lower plate 1002. The upper plate 1001 and the lower plate 1002 are correspondingly provided with rivet holes 101 and bolt press-fitting holes 102.

[0066] like Figure 5 As shown, the bushing processing unit 10 includes a bushing conveying module, a bushing grabbing module, a diameter reduction module 19 and an outer diameter detection module. The bushing conveying module is used to automatically convey the bushing, and the bushing grabbing module is used to take the bushing to the diameter reduction module 19 and the outer diameter detection module. The diameter reduction module 19 is a commonly used diameter reduction device, which is used to perform diameter reduction processing on the bushing, and the outer diameter detection module is used to detect the outer diameter size of the bushing.

[0067] Specifically, the bushing conveying module includes a first vibrating loading tray 11 and a bushing conveyor belt 12 arranged on one side of the first vibrating loading tray 11. The first vibrating loading tray 11 is used to automatically load the bushing, and the bushing conveyor belt 12 is used to automatically convey the bushing. The bushing conveyor belt 12 is a roller-driven belt conveying structure. A plurality of anti-error plates (not shown in the figure) are arranged in the bushing conveyor belt 12. A bushing placed in the wrong direction on the bushing conveyor belt 12 will flip over when it moves to the anti-error plate position. When the bushing is placed normally upward, there is no contact between its lower end position and the anti-error plate. When the bushing is placed in the wrong direction, its lower end position will contact the anti-error plate. As a result, the bushing is forced to rotate during the movement until it returns to the normal upward direction.

[0068] In addition, the bushing grabbing module includes a horizontal pushing cylinder 13, which is used to drive two lifting cylinders 14 to make synchronous and horizontal reciprocating movements. Here, the output end of the horizontal pushing cylinder 13 is provided with a fixed frame, and the two lifting cylinders 14 are set on the fixed frame, thereby performing horizontal reciprocating movements. The lifting cylinder 14 is provided with a grabbing tooling 15, and the grabbing tooling 15 is used to grab the bushing.

[0069] Furthermore, the outer diameter detection module includes an inspection station 16, which is driven to rotate by a rotary motor 17. The inspection station 16 is used to set a bushing. A detection sensor 18 is provided on one side of the inspection station 16, and the detection sensor 18 is used to detect the outer diameter of the bushing.

[0070] like Figure 6 As shown, the lower plate conveying unit 30 is used to automatically convey the lower plate, and the lower plate conveying unit 30 is provided with a second error-proofing component, which is used to separate the lower plate placed in the wrong direction from the lower plate conveying unit 30. The lower plate conveying unit 30 includes a lower plate conveyor belt 31 and a defective product recovery frame 32 provided at the head end of the lower plate conveyor belt 31. The lower plate is placed on the lower plate conveyor belt 31 for transportation by manual or robotic means. The second error-proofing component includes a first sensor provided on the lower plate conveyor belt 31. The first sensor is located at the lower plate conveyor belt 31. The first sensor is used to detect the head end position of the lower plate and thereby determine whether the direction of the lower plate is correct. The lower plate conveyor belt 31 can be reversed and drive the lower plate with the wrong direction to fall into the defective product recovery box 32. The lower plate conveyor belt 31 is also a belt transmission structure combined with a roller. When the lower plate 1002 is placed correctly, its lower end falls into the lower plate conveyor belt 31. When it is placed in the reverse direction, the whole is located above the lower plate conveyor belt 31. When passing through the first sensor, the first sensor detects the reversely placed lower plate, thereby stopping and reversing, causing it to fall into the defective product recovery box 32.

[0071] like Figure 7-Figure 8As shown, the upper plate conveying unit 20 is used to automatically convey the upper plate, and the upper plate conveying unit 20 is provided with a first error-proofing component, which is used to separate the upper plate placed in the wrong direction from the upper plate conveying unit 20, and the upper plate conveying unit 20 includes an upper plate conveyor belt 21 and a recovery container 22 arranged on one side of the upper plate conveyor belt 21. The upper plate conveyor belt 21 is also a belt conveyor structure, and the first error-proofing component includes a connecting frame 23 arranged on one side of the upper plate conveyor belt 21, and a recovery cylinder 24 and a second sensor 25 are provided on the connecting frame 23. Since the height of the upper plate on the upper plate conveyor belt 21 is different when the upper plate is placed correctly and when it is placed in reverse, the height of the upper plate can be detected by the second sensor 25 and thereby determine whether the direction of the upper plate is correct, and the recovery cylinder 24 is used to drive the push plate 28 and push the upper plate with the wrong direction to fall into the recovery container 22,

[0072] At the same time, a stop station 26 is provided at the end of the upper plate conveyor belt 21, on which a stop sensor 27 is also provided. When the upper plate is transported to the stop station 26, the sensor detects that there is an upper plate at the station, and the upper plate conveyor belt 21 stops working.

A first clamp 916 is respectively provided at both ends of the first rotating frame 915. The first clamp 916 is respectively used to clamp the lower plate and the bushing.

[0075] like Figure 11-12As shown, the second transport unit 90b is used to transport the upper plate to the riveting unit 50 and to transport the bolts to the pressing unit 60. The second transport unit 90b includes a second manipulator 921. The second manipulator 921 is provided with a second transmission frame 922 and a third rotating motor 923. The third rotating motor 923 is used to drive the second transmission frame 922 to rotate. The second transmission frame 922 is provided with a fourth rotating motor 924. The output end of the fourth rotating motor 924 is linked to a second rotating frame 925. The two ends of the second rotating frame 925 are respectively provided with an upper plate suction cup 926 and a bolt suction tooling. The upper plate suction cup 926 is used to adsorb the upper plate. The bolt suction tooling includes a suction cup 927 and a plurality of electromagnetic suction columns 928 provided on the suction cup. The electromagnetic suction columns 928 are used to adsorb bolts.

[0076] In addition, the third transport unit 90c is used to transport the semi-finished products that have been riveted from the riveting unit 50 to the pressing unit 60, and to move the finished products that have completed bolt pressing in the pressing unit 60 out of the pressing unit 60. The structure of the third transport unit 90c can be similar to the structure of the above-mentioned transport unit, that is, it can be a rotatable double-head clamping structure, which will not be further described here.

[0077] like Figure 13-15 As shown, the riveting unit 50 is used to press the lower plate and the bushing together, and to press the upper plate and the lower plate. The riveting unit 50 includes an upper riveting module, a height adjustment assembly, and a lower riveting module that are relatively arranged.

[0078] The upper riveting die set is driven by a riveting cylinder to perform lifting movements, and the upper riveting die set includes a riveting upper plate 51, a riveting connecting block 52 is provided at the lower end of the riveting upper plate 51, and a plurality of riveting columns 521 are provided around the bottom of the riveting connecting block 52, and the riveting columns 521 are used to press rivets between the upper plate and the lower plate, and a movable pressing block 53 is provided in the riveting connecting block 52, and the movable pressing block 53 can perform lifting movements in the riveting connecting block 52, and the movable pressing block 53 is used to press the lower plate and the bushing.

[0079] In addition, a height adjustment component is arranged on the upper riveting module, and the height adjustment component includes an adjusting cylinder 54, an adjusting rod 55, a first adjusting block 56, and a second adjusting block 57. The two adjusting rods 55 are arranged horizontally and connected to the output end of the adjusting cylinder 54. The first adjusting block 56 and the second adjusting block 57 are respectively arranged on one adjusting rod 55. The two adjusting rods 55 both pass through the riveting connecting block 52 and the tail ends are connected to the limiting block 541. The limiting block 541 cannot penetrate into the riveting connecting block 52. The second adjusting block 57 can penetrate into the movable pressing block 53. The first adjusting block 56 and the second adjusting block 57 can contact the movable pressing block 53 during the synchronous movement and drive the movable pressing block 53 to make lifting movements.

[0080] Here, the movable pressure block 53 and the riveted connection block 52 are both hollow structures. The movable pressure block 53 is confined within the riveted connection block 52 and is restricted to vertical lifting and lowering movements therein. The first adjustment block 56 is located at the upper end of the second adjustment block 57. The contact surface between the first adjustment block 56 and the movable pressure block 53, as well as the contact surface between the second adjustment block 57 and the movable pressure block 53 are both inclined surfaces, which drive the movable pressure block 53 to move up and down within the riveted connection block 52 through the cooperation of the inclined surfaces.

[0081] In addition, the lower riveting module includes a riveted lower plate 58, and a lower clamp 59 is provided on the riveted lower plate 58. The lower clamp 59 is used to set the upper plate, the lower plate and the bushing. The bushing positioning pin 591 is provided in the lower clamp 59, and a plurality of lower plate positioning pins 592 are provided at the upper end of the lower clamp 59. The bushing positioning pin 591 is for the bushing to be inserted and positioned, and the lower plate positioning pin 592 is for the lower plate to be inserted and positioned.

[0082] Therefore, when the lower end of the movable pressure block 53 is exposed below the riveting connection block 52, the lower plate and the bushing can be pressed together. When the movable pressure block 53 rises and retracts into the riveting connection block 52, the riveting connection block 52 can perform a riveting action through the riveting column 521.

[0083] like Figure 16 As shown, the press-fitting unit 60 is used to press the bolts into the upper plate and the lower plate. The press-fitting unit 60 includes an upper press-fitting die set and a lower press-fitting die set that are oppositely arranged.

The upper limit posts 63 are provided around the press-fitting block 62 .

[0085] In addition, the lower press-fitting module includes a press-fitting lower plate 64, on which a base 641 and a lower limit column 642 are provided.

After coding is completed, it can also enter the corresponding packaging table for manual or mechanical packaging.

[0089] The production system of the present invention mainly includes the following production steps during production:

[0090] In step one, the operator pours the bushing into the first vibrating loading tray 11, and the bushing is conveyed to the bushing conveyor belt 12 through vibration; during the conveying process of the bushing, the bushing conveyor belt 12 automatically adjusts the direction of the bushing through the anti-error plate, and flips the bushing with the wrong direction. When the bushing reaches the end of the conveyor belt, the upper part of the bushing conveyor belt 12 can be illuminated by a sensor to control the operation to stop. The lower end of the bushing conveyor belt 12 can also be illuminated by a sensor, and an alarm will be prompted if a bushing with the wrong direction is found; at the same time, the bushing at the end of the bushing conveyor belt 12 is grabbed by the grabbing tool 15 in the bushing grabbing module and enters the diameter reduction module 19 for diameter reduction operation, and the bushing that has been reduced is grabbed to the outer diameter detection module for outer diameter detection.

[0091] Step 2: The lower plate is placed into the lower plate conveying unit 30 for transportation manually or mechanically, and the lower plate placed in the wrong direction is returned to the defective product recovery frame 32 for recovery through the second error-proofing component. The sensor stops when the lower plate reaches the specified position.

[0092] Step three: manually or mechanically place the upper plate into the upper plate conveying unit 20 for transportation, and push the upper plate placed in the wrong direction into the recovery container 22 for recovery through the first error-proofing component. The sensor stops the machine when the upper plate reaches the specified position.
