DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the 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 the embodiments.

[0039] Embodiment: This embodiment provides a fully automatic welding and buckle assembly system for automobile painting accessories. Taking the welding and buckle assembly of automobile skirts as an example, see Figure 1-10Specifically, it includes two conveying lines 1, two conveying components 2, a welding component 3, an assembly component 4 and a feeding component 5. The two conveying components 2 move back and forth on the conveying line 1. The welding components 3 and the assembly components 4 are staggered on both sides of the conveying line 1. The assembly component 4 is provided with a batch installation component 42 for batch picking and assembling plastic buckle bodies 101. The batch installation component 42 can grab a number of plastic buckle bodies 101 at the same time. A detection component 58 is provided on one side of the feeding component 5. The detection component 58 is used to detect whether there is a plastic buckle body 101 on the feeding component 5;

[0040] The conveyor line 1 is provided with loading and unloading positions at both ends, and the skirt body 100 is placed on the two conveyor assemblies 2. The two conveyor assemblies 2 are sequentially conveyed to the welding assembly 3 position by the two conveyor lines 1. The coating accessories on one skirt body 100 are welded by the welding assembly 3. Then the skirt body 100 is conveyed to the assembly assembly 4 position for assembly of the plastic buckle body 101, and the other conveyor line 1 conveys the other skirt body 100 to the welding assembly 3 position for welding. The skirt body 100 that has completed the assembly of the plastic buckle body 101 first will be It is transported to the unloading end of the conveyor line 1. At this time, the other skirt body 100 will be located at the assembly component 4 position, and the assembled skirt body 100 will be removed from the conveying component 2. After removal, the conveying component 2 will move in the opposite direction to the loading end of the conveyor line 1 and reload. Compared with a single conveyor line 1, the two processes can be connected in series, but there will be a problem of long waiting time for welding components 3 or assembling components 4. The two conveyor lines 1 can drive the conveying components 2 to move back and forth in an alternating manner, thereby shortening the waiting time for welding components 3 and assembling components 4 and improving production efficiency.

[0041] As a preferred embodiment, the number of plastic snap bodies 101 grabbed by the batch installation component 42 each time is an integer multiple of the number of buckle positions on the skirt body 100, so that the batch installation component 42 can completely assemble the plastic snap bodies 101 of each skirt body 100 at one time, avoiding the problem of multiple material extraction during the process of assembling a skirt body 100, thereby improving the efficiency of assembly; in addition, this can also utilize the time waiting for the arrival of the next skirt body 100 to extract materials, effectively utilize the waiting time, and further improve the assembly efficiency.

[0042] In the specific implementation process, Figure 2 and Figure 3 As shown, the two transport assemblies 2 each include a moving plate 21 connected to the two conveyor lines 1, and a profile block 22 that fits the outer wall of the skirt body 100 is fixedly disposed on the upper surface of the moving plate 21, and a row of positioning members 23 are disposed on the upper surface edge of the moving plate 21, and the positioning members 23 include a piston cylinder, a connecting rod and a rubber head, and the output end of the piston cylinder is connected to one end of the connecting rod, and the rubber head is installed at the other end of the connecting rod;

[0043] The profiling block 22 on the movable plate 21 is adapted to the outer wall of the skirt body 100, and the connecting rod is driven to move by multiple piston cylinders so that the rubber head at the end of the connecting rod fits with the outer wall of the skirt body 100, thereby fixing the position of the skirt body 100 and facilitating the subsequent installation of the plastic buckle body 101; the movable plate 21 is connected to the conveyor line 1, and the conveyor line 1 drives the movable plate 21 to move, transports the skirt body 100, and quickly switches between various workstations to improve processing efficiency.

[0044] In the specific implementation process, Figure 2 and Figure 4 As shown, the welding assembly 3 includes a welding robot 31, an ultrasonic welding head 32 is fixedly provided at the end of the welding robot 31, and an ultrasonic welding head storage bracket 33 for supporting the ultrasonic welding head 32 is provided on one side of the welding robot 31;

[0045] The welding robot 31 drives the ultrasonic welding head 32 to weld the coating accessories to the skirt body 100. When the ultrasonic welding head 32 is not in use, it will be driven and placed on the ultrasonic welding head storage bracket 33 to relieve the pressure on the welding robot 31 and increase the service life of the equipment. In addition, three ultrasonic welding heads 32 can be stored on the ultrasonic welding head storage bracket 33 and can be recycled to facilitate the cooling of the ultrasonic welding head 32. The ultrasonic welding head 32 includes a welding head and a clamp for clamping the welding head.

[0046] In the specific implementation process, Figure 5 , Figure 6 and Fig. 9 As shown, the assembly component 4 includes an assembly robot 41, the end of which is connected to a batch installation component 42. The batch installation component 42 includes a fixed frame 421, a cylinder 422, a push rod 423, a limit ring 424 and a snap clamp 425 connected to the end of the assembly robot 41. There are several cylinders 422, and the number of push rods 423, the limit ring 424 and the snap clamp 425 corresponds to the number of cylinders 422. The cylinders 422 are arranged in two rows at the upper inner part of the fixed frame 421, the limit ring 424 is arranged at the lower end of the fixed frame 421 and corresponds to the cylinder 422 one by one. Push rods 423 are inserted in the limit rings 424, and the upper ends of the push rods 423 are respectively connected to the output ends of the cylinders 422. The lower ends of the push rods 423 are fixed with snap clamps 425, and the lower surfaces of the snap clamps 425 are provided with snap clamp slots 426.

[0047] The batch installation parts 42 are driven by the assembly robot 41 to first take the plastic buckle body 101 from the feeding component 5. When taking the plastic buckle body 101, the fixing frame 421 is moved above the feeding component 5, and the upper end of the plastic buckle body 101 is inserted into the buckle chuck slot 426 of the buckle chuck 425 by the cylinder 422. When installing the plastic buckle body 101, the push rod 423 is pushed by the cylinder 422 to move, and the push rod 423 drives the buckle chuck 425 to move synchronously, so that the buckle chuck 425 drives the plastic buckle body 101 to leave the position of the plane where the other gas plastic buckle body 101 is located, so that the plastic buckle body 101 in the buckle chuck slot 426 is inserted into the skirt body 100 from the side of the buckle position. Since the part of the plastic buckle body 101 inserted into the skirt body 100 has a concave cross-section ( Fig.10 ), the groove is firmly buckled with the skirt body 100, when the cylinder 422 rises, the plastic buckle body 101 is disengaged from the buckle chuck slot 426, and the cylinder 422 inserts the plastic buckle bodies 101 into the skirt body 100 side by side, avoiding interference between the plastic buckle bodies 101 during installation, and realizing batch retrieval of the plastic buckle bodies 101, and then installing them on the skirt body 100 in sequence, saving material retrieval time and improving processing efficiency.

[0048] In the specific implementation process, Figure 7 and Figure 8 As shown, the feeding assembly 5 includes two vibrating plates 51, a fixed frame 53 located between the two vibrating plates 51, and straight rods 56 located on both sides of the fixed frame 53. The discharge ports of the two vibrating plates 51 are both equipped with conveying pipes 52. The ends of the conveying pipes 52 away from the conveying vibrating plates 51 are both located in the grooves in the middle of the fixed frame 53. A material dividing bottom plate 54 is slidably arranged in the fixed frame 53. A plurality of material dividing grooves 55 are respectively provided on the edges of both sides of the material dividing bottom plate 54. An infrared sensor 57 is provided above the outlet end of the conveying pipe 52 to detect the material. The member 58 is arranged on one side of the fixed frame 53, and a moving member for driving the material distribution bottom plate 54 to move is arranged in the fixed frame 53. The detection member 58 includes a support plate 581 and a buckle detection limit sensor 582. The buckle detection limit sensor 582 is arranged on the upper surface of the support plate 581, and the number and arrangement of the buckle detection limit sensors 582 correspond to the buckle chuck 425 one by one. The moving member includes a servo motor, a screw rod, a slide rail and a slider. The lower end of the material distribution bottom plate 54 is connected to the screw rod and the slider respectively, and the motor is connected to the end of the screw rod;

[0049] The vibrating plate 51 delivers the plastic buckle body 101 in the same direction from the conveying pipe 52 to the dividing groove 55 of the dividing bottom plate 54. Since the dividing bottom plate 54 fits the end of the conveying pipe 52, the plastic buckle body 101 is blocked in the conveying pipe 52. When the dividing groove 55 is parallel to the conveying pipe 52, the frontmost plastic buckle body 101 will be squeezed into the dividing groove 55 by the rear plastic buckle body 101, and the dividing groove 55 can only accommodate one plastic buckle body 101 at a time. The infrared sensor 57 detects whether there is a plastic buckle body 101 in the dividing groove 55, and the driving member drives the dividing bottom plate 54 to move, so that the two rows of dividing grooves 55 of the dividing bottom plate 54 are filled with plastic buckles. The buckle body 101 can automatically and quickly arrange the plastic buckle body 101 in order, which is convenient for the subsequent batch installation parts 42 to be taken and improve the processing efficiency; the assembly robot 41 drives the fixed frame 421 to move to the top of the buckle detection limit sensor 582 and move downward. If the buckle chuck 425 is in an unloaded state, the buckle chuck slot 426 of the buckle chuck 425 will be sleeved on the outside of the buckle detection limit sensor 582. At this time, the buckle detection limit sensor 582 will not be pressed. When the plastic buckle body 101 exists in the buckle chuck slot 426, the plastic buckle body 101 will contact the buckle detection limit sensor 582, causing the buckle detection limit sensor 582 to be pressed, thereby triggering an alarm.

[0050] After the buckle detection limit sensor 582 is triggered to alarm, as a preferred embodiment, the detection member 58 records the number of plastic buckle bodies 101 and their loading positions, and then continues to perform the material picking action, the cylinder 422 corresponding to the buckle chuck 425 loaded with the plastic buckle body 101 does not move, and the cylinder 422 corresponding to the other unloaded buckle chuck 425 drives the buckle chuck 425 to extend, so that the unloaded buckle chuck 525 grabs the plastic buckle body 101, so there is no need to stop the machine to remove the plastic buckle body 101, making the production process more consistent;

[0051] As another embodiment, when the buckle detection limit sensor 582 detects that there is still a plastic buckle body 101 in the buckle chuck 425, the assembly component 4 stops the moving parts and sounds an alarm to remind the operator to remove the plastic buckle body 101 and check the assembled skirt body; after taking out the plastic buckle body 101 remaining in the buckle chuck slot 426, the assembly component 4 drives the batch installation component 42 to move to the feeding component 5, and loads the plastic buckle body 101 into the unloaded buckle chuck 425. By detecting whether there is a plastic buckle body 101 in the buckle chuck 425 before the batch installation component 42 takes the material, it is possible to promptly alarm for the problem of missing installation of the skirt body 100, thereby avoiding the outflow of defective products, and also preventing the two plastic buckle bodies 101 from being squeezed and damaged when taking the material, thereby causing waste of materials.

[0052] A fully automatic welding and buckle assembly method for automobile painting accessories, applied to the fully automatic welding and buckle assembly system for automobile painting accessories as described above, comprising:

[0053] The skirt loading step is to fix the skirt body 100 on the two conveying components 2;

[0054] In the step of loading the plastic buckle body 101, the detection member 58 detects whether there is still the plastic buckle body 101 on the batch installation member 42:

[0055] If there are buckles on the batch installation part 42, the number of plastic buckle bodies 101 and their loading positions are recorded, and then the assembly component 4 drives the batch installation part 42 to move to the feeding component 5 to load the plastic buckle body 101 to the unloaded position;

[0056] Welding step: welding assembly 3 welds the coating accessories to the skirt body 100;

[0057] Buckle assembly step: the assembly component 4 drives the batch installation component 42 to assemble the plastic buckle body 101 loaded thereon to the buckle position of the skirt body 100;
