Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0030] The material moving component 9 is arranged inside the machine body 1 and extends to the outside of the machine body 1, and is laterally connected to the external conveying equipment, so that the material moving component 9 can smoothly push the processed parts (the example product of this scheme is the rotor) on the external conveying equipment onto the workpiece pallet 14 in this device, so that the workpiece pallet 14 cooperates with the third linear module 10 to move the processed parts into the assembly stations of the rivet component 11, the component grabbing component 7, and the robot handling manipulator 5 in sequence according to the preset program for assembly operations. Finally, after the assembly operation is completed, the workpiece pallet 14 is driven by the third linear module 10 to move to the discharge position of the rotor discharge and feeding rack 13, and the processing parts that have completed the assembly work are pushed out of this device through the pushing component 15, so that the processing parts re-enter the lower end of the conveying equipment for output. Through the design of this scheme, the degree of automation of the device is high, manual operation is reduced, the intensity of manual labor is reduced, the assembly accuracy is improved, the quality of the product is improved, and at the same time, the production efficiency is improved to meet the needs of large-scale production.

[0031] Specifically, the first linear module 8 adopts a screw module, which is an existing mature technology. The specific structure and working principle can be easily implemented by those skilled in the art based on relevant technologies, so they will not be repeated here. This allows the component grasping assembly 7 to be accurately controlled to move laterally, so that the first clamping jaw 704 and the second clamping jaw 705 on the component grasping assembly 7 can smoothly perform component grasping operations in the storage area 6.

[0032] The rivet pressing component 11 includes a pressing plate 1101 and a lifting module 1102 for driving the pressing plate 1101 to move up and down. A fixing frame 1103 is installed between the lifting module 1102 and the processing table 2 to connect.

[0033] The rivet pressing component 11 is arranged between the robot handling manipulator 5 and the component grabbing assembly 7, so that each time the workpiece completes an assembly process, it can be returned to the rivet pressing component 11 through the third linear module 10 for a clamping operation.

[0034] Specifically, the robot handling manipulator 5 adopts a SCARA (Selective Compliance Assembly Robot Arm) robot arm. The SCARA robot arm is an existing mature technology. The specific structure and working principle can be easily implemented by those skilled in the art based on relevant technologies, so they are not described in detail. The SCARA robot arm grabs the rivet ejected by the rivet ejection cylinder 402 in the rivet feeding component 4 to perform rivet installation operations on the workpiece.

[0035] The component grabbing assembly 7 includes a first mounting frame 701 and a second lifting assembly 702. The second lifting assembly 702 is slidably connected to a connecting plate 703. The connecting plate 703 is respectively provided with a first clamping jaw 704 and a second clamping jaw 705. A storage area 6 for storing assembled workpieces is provided below the first clamping jaw 704 and the second clamping jaw 705.

[0036] Furthermore, the first clamp 704 and the second clamp 705 adopt electric vacuum clamps. Electric vacuum clamps are an existing mature technology. The specific structure and working principle can be easily implemented by those skilled in the art based on relevant technologies, so they are not described in detail. The first clamp 704 and the second clamp 705 are used to grab the upper end cover and the balance block at the first storage station 601 and the second storage station 602 in the storage area 6, and install them on the workpiece in turn to complete the assembly operation.

[0037] Specifically, the second lifting assembly 702 adopts a screw module, which is an existing mature technology. The specific structure and working principle can be easily implemented by those skilled in the art based on relevant technologies, so they will not be repeated here. The screw module makes it possible to accurately control the connecting plate 703 to move up and down, so that the assembly accuracy of the first clamp 704 and the second clamp 705 is high.

[0038] The material storage area 6 includes a first material storage station 601 and a second material storage station 602 . The first material storage station 601 and the second material storage station 602 are arranged in parallel with the first clamping jaw 704 and the second clamping jaw 705 .

[0039] According to the product assembly requirements, the upper end cover and the balance block are stored respectively on the first storage station 601 and the second storage station 602, so that the subsequent component grabbing assembly 7 can smoothly carry out the component grabbing operation in the storage area 6 and complete the assembly of the processed parts.

[0040] The material moving component 9 includes a material moving plate 901 and a second linear module 902 for driving the material moving plate 901 to move. A bracket 903 is installed between the second linear module 902 and the machine body 1 to connect.

[0041] The bracket 903 is connected to the inside of the machine body 1 across the external conveying device, so that the material transfer plate 901 installed on the bracket 903 can push the workpiece on the external conveying device into the workpiece pallet 14 in the device for assembly operation.

[0042] The rivet feeding component 4 includes a storage box 401 and a discharge trough 403. One end of the discharge trough 403 is provided with a rivet ejecting cylinder 402 for ejecting rivets.

[0043] Furthermore, a baffle plate is connected to the outer side of the opening of the discharge groove 403 , the opening thickness of the discharge groove 403 is smaller than the rivet head diameter of the rivet, and the discharge groove 403 is arranged at an angle.

[0044] Specifically, through the inclined arrangement of the discharge trough 403, the rivets in the discharge trough 403 can smoothly move toward the bottom and fall to the rivet ejection cylinder 402, so that the rivet ejection cylinder 402 can smoothly eject the rivets, thereby facilitating the robot handling manipulator 5 to remove the rivets and perform the rivet installation work.

[0045] A first lifting assembly 405 is installed inside the material storage box 401 , and a movable plate 406 is slidably connected to one side of the first lifting assembly 405 , and a discharge port 404 is provided above the movable plate 406 .

[0046] Furthermore, the upper and lower parts of the outer side of the discharge port 404 are both obliquely connected with guide plates, so that when the first lifting component 405 drives the movable plate 406 to move up and down in the storage box 401, a single rivet on the movable plate 406 can be ejected from the storage box 401, and the ejected rivet falls smoothly into the discharge trough 403 along the inclined guide plate, and the baffle plate outside the opening of the discharge trough 403 can prevent the rivet from falling outside the discharge trough 403. At the same time, the opening thickness of the discharge trough 403 is smaller than the rivet head diameter, so that the rivet rod falls into the discharge trough 403, and the head is hung on the discharge trough 403, so that the rivets are arranged on the discharge trough 403, sliding downward in turn, waiting for subsequent ejection operations.

[0047] A positioning sensor 12 for sensing incoming materials is installed at the feeding end of the third linear module 10 , and a workpiece pallet 14 is slidably connected to the third linear module 10 .

[0048] Furthermore, after the material moving component 9 pushes the workpiece into the device, the position of the incoming material is detected by the positioning sensor 12 and converted into an output signal, so that the electrical components on the device enter the working state.

[0049] The machine body 1 is equipped with a PLC control panel 3 and an alarm for warning the staff. The machine body 1 is equipped with a filtering system and an air source device.

[0050] A PLC (Programmable Logic Controller) control panel controls the switching of electrical components on the device to achieve automated assembly of the device. The alarm can be an audible or visual alarm that can sound an alarm when a fault occurs.

[0051] Working principle: First, the material moving plate 901 of the material moving component 9 cooperates with the second linear module 902 to push the workpiece onto the workpiece tray 14 of the third linear module 10. Then, the third linear module 10 moves the workpiece to the area of ​​the rivet component 11 according to the preset program, and presses the rotor on the workpiece tray 14 through the rivet component 11. Three positioning pins are put on the bottom of the workpiece, and then it is moved to the second clamping jaw 705 and the first clamping jaw 704 of the component grabbing component 7 to assemble the upper end cover and the balance block. Then, the workpiece is moved into the robot moving unit through the third linear module 10. The robot transport manipulator 5 grabs the rivets in the rivet loading component 4 through the robot handling manipulator 5 and performs the rivet installation action. After the rivets are installed, it moves to the rivet pressing component 11 to complete the rivet flattening operation, so that the assembled parts can be tightly attached. Then, it moves in front of the pushing component 15 and pushes the workpiece on the workpiece tray 14 out of the body 1 through the pushing component 15, so that it enters the lower end of the conveyor line for output. Through the application of automated assembly equipment, the assembly process of the compressor rotor becomes more efficient, accurate and stable, realizing the automation, efficiency and precision of the compressor rotor assembly.

[0052] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
