[0027] In this embodiment, the first loading robot 2 is used to grab the second part, and the second loading robot 3 is used to grab the first part. When in use, the first loading robot 2 grabs the second part into the intersection A, and then the loading and unloading robot takes the second part on the first loading robot, and then the loading and unloading robot installs the second part on the welding device, and the second loading robot 3 grabs the first part onto the first detector, and the first detector detects the first part. If the first part meets the preset requirements, the loading and unloading robot grabs the first part on the first detector and places it on the welding device to cooperate with the second part. If the first part does not meet the preset requirements, the screening robot 29 grabs the first part on the first detector. Take it to the designated place; then the welding device welds the first part and the second part; after welding, the loading and unloading robot grabs the welded first part and the second part into the travel range of the first detection robot 4, and then the first detection robot 4 grabs the welded first part and the second part onto the second detector, wherein the material output end of the second detector is within the travel range of the second detection robot 5, so the second detection robot 5 classifies and places (collects) the welded and detected first part and the second part according to the detection result of the second detector; after such setting, the problem that the existing welding machine can only weld but cannot judge the qualified status of the product is solved.

[0028] As a preferred mode, the frame 1 is further provided with a first loader and a second loader, the output end of the first loader and the output end of the second loader are both within the travel range of the first loader manipulator 2, a preset gap is set between the first loader and the second loader, a preset gap is set between the first loader and the welding device, and a preset gap is set between the second loader and the welding device. A first sensor 6 is set at the output end of the first loader, and a second sensor 7 is set at the output end of the second loader. The first sensor 6 and the second sensor 7 are both connected to the first loader manipulator 2 by signal. After such setting, the first loader is used to hold the second part and load the second part, and the second loader is used to hold the third part and load the third part. When the first loader manipulator 2 receives the first sensor 6, the first loader manipulator 2 moves to the output end of the first loader to grab the second part; when the first loader manipulator 2 receives the signal of the second sensor 7, the first loader manipulator 2 moves to the output end of the second loader to grab the third part, thereby loading the third part. The user determines whether to use the first loader or the second loader according to needs.

[0029] As a preferred mode, the first feeder includes a vibrating feeder 8, a chain plate elevator 9, and a discharge frame 10. The lower end of the chain plate elevator 9 extends into the discharge frame 10, and the upper end of the chain plate elevator 9 is in the vibrating feeder 8. The output end of the vibrating feeder 8 is within the travel range of the first feeding manipulator 2. The output end of the vibrating feeder 8 is provided with the first sensor 6. After such a setting, when in use, the user puts the second part into the discharge frame 10, and then the chain plate elevator 9 transfers the second part in the discharge frame 10 to the vibrating feeder 10, and then the second part moves to the output end of the vibrating feeder 8 under the action of the vibrating feeder 8. At this time, the second part touches the first sensor, so that the first feeding manipulator 2 grabs the second part. In this way, the chain plate elevator 9 is adopted, so that the second part can be transported from a position lower than the welding device to a state flush with the welding device. In this way, the process of transporting the second part from a position lower than the welding device to a height flush with the welding device can be omitted. Thereby increasing the production speed.

[0030] As a preferred mode, the first detector includes a first rodless cylinder 11, a first mounting plate 12, a first tray 13, and a first camera 14. The first rodless cylinder 11 and the first camera 14 are both fixedly mounted on the frame 1. The first mounting plate 12 is fixedly mounted on the execution end of the first rodless cylinder 11. The first mounting plate 12 is provided with a first rotating motor 15 with an output shaft vertically upward. The first tray 13 is fixedly mounted on the output shaft of the first rotating motor 15. The first camera 14 is arranged on one side between the two ends of the first rodless cylinder 11 through a first lifting device. The shooting direction of the first camera 14 is parallel to the upper surface of the first tray 13. After such arrangement, the first tray 13 is used to carry the first part or the second part. After that, the first rodless cylinder 11 moves the first part or the second part located on the first tray 12 to the first camera 14 for detection. If the detection is qualified, the qualified first part or the second part is moved and installed on the welding device by the loading and unloading robot. If it is unqualified, the first part or the second part is moved and output to the designated area by the screening robot 29.

[0031] As a preferred embodiment, the loading and unloading robot includes a rotating disk 16, a rotating servo motor 17, and a reducer 18.

The rotating disk 16 is fixedly arranged on the output shaft of the reducer 18. The upper surface of the rotating disk 16 is evenly distributed with 5 lifters 19 equidistantly around its center. Each of the lifters 19 is provided with a first clamping hand 20, and the clamping end of the first clamping hand 20 faces the outside of the rotating disk 16. The first detector and the second detector are separated on opposite sides of the rotating disk 16. The welding device is located on one side of the rotating disk 16, and the connecting line segment from the welding device to the center of the rotating disk 16 is perpendicular to the connecting line segment from the first detector to the center of the rotating disk 16. After such arrangement, the first clamping hand 20 located on the rotating disk 16 realizes interaction with the first detector, the second detector and the welding device under the rotation of the rotating disk 16. When the first clamping hand 20 on the rotating disk 16 rotates to the first detector, it can clamp the first part that has been inspected on the first detector. Then, when the rotating disk 16 continues to rotate to the welding device, the lifter 19 drives the first clamping hand 20 to rise and fall and approach the welding device, so as to place the first part on the welding device. When welding is completed, the first clamping hand 20 on the rotating disk 16 rotates to the welding device under the action of the rotating disk 16 to clamp the welded part, and then moves to the second detector under the continued rotation of the rotating disk 16. Then the first detection robot 4 clamps the welded part on the first clamping hand 20 to the second detector, and the second detector detects the weld and other parameters.

[0032] As a preferred mode, the welding device comprises an upper electrode 21 and a lower electrode, wherein the upper electrode 21 is a positive electrode, the lower electrode is a secondary electrode, a pressure block joint is provided on the lower surface of the upper electrode 21, and the lower electrode is a second clamping hand 22; when one of the first clamping hands 20 is located directly below one of the second clamping hands 22 under the action of the rotating disk 16, the second clamping hand 22 is located within the range of the lifting stroke of the first clamping hand 20. After such a setting, when in use, the second clamping hand 22 clamps the first part, and then the first loading manipulator 2 places the second part or the third part on the first part, and then the upper electrode is pressed down to press the second part or the third part, and then the power is turned on for welding. Among them, when in use, the pressing block joint matching the welded parts can be replaced as needed. For example, when the first part and the second part need to be welded together, the second part is located above the first part, and the pressing block joint matching the second part is used; when the first part and the third part need to be welded together, the third part is located above the first part, and at this time, the positive electrode needs to be replaced with a pressing block joint matching the third part.

[0033] As a preferred mode, the second detector includes a second rodless cylinder 23, a second mounting plate 24, a second pallet 25, and a second camera 26. The second rodless cylinder 23 and the second camera 26 are both fixedly mounted on the frame 1. The second mounting plate 24 is fixedly mounted on the execution end of the second rodless cylinder 23. The second mounting plate 24 is provided with a second rotating motor 27 with an output shaft pointing vertically upward.

The second camera 26 is disposed on one side between the two ends of the second rodless cylinder 23 through a second lifting device. The shooting direction of the second camera 26 is parallel to the upper surface of the second pallet 25. After such a setting, the rodless cylinder 32 drives the second pallet 25 to move, so that the welded parts on the pallet 25 are transported to the second camera 26 for detection. The second lifting device is used to adjust the position of the second camera 26 relative to the welded parts.
