DETAILED DESCRIPTION

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] like Figure 1As shown, an automated production line for annular parts includes a first CNC lathe 1 and a second CNC lathe 2, the spindle center lines of the first CNC lathe 1 and the second CNC lathe 2 are perpendicular to each other, and also includes a first robot 3 that can clamp the workpiece to be processed to the first CNC lathe 1 and the second CNC lathe 2 for processing, a flipping mechanism 4 is provided between the first CNC lathe 1 and the second CNC lathe 2 to assist the first robot 3 in flipping the workpiece to be processed, and also includes a first material buffer area 5, and the first material buffer area 5 is within the clamping range of the first robot 3.

[0020] In addition, it also includes a second robot 6. A flaw detector 7, a cleaning machine 8, a comparator 9, a marking machine 10 and a second material buffer area 11 are arranged in sequence downstream of the second CNC lathe 2. A material temporary storage area 12 is arranged on the flaw detector 7. The material temporary storage area 12 is within the clamping range of the first robot 3 and the second robot 6. The cleaning machine 8, the comparator 9, the marking machine 10 and the second material buffer area 11 are within the clamping range of the second robot 6.

[0021] In this embodiment, a product tray 13 for placing workpieces to be processed is disposed on the first material buffer area 5 , and a product tray 13 for placing workpieces to be processed is disposed on the second material buffer area 11 .

[0022] In this embodiment, a rotatable worktable is provided on the flipping mechanism 4, and a clamping cylinder for clamping the workpiece to be processed is provided on the worktable. When the flipping mechanism 4 is used, the first robot 3 clamps the workpiece to be processed after being processed by the first CNC lathe 1, and places it on the worktable of the flipping mechanism 4. The clamping cylinder on the worktable clamps the workpiece to be processed, and then the worktable is turned around so that the first robot 3 can clamp the other end of the workpiece to be processed, and put the workpiece to be processed into the second CNC lathe 2 again in the clamped state, so that the flipping of the workpiece can be realized.

[0023] In addition, in the present embodiment, the first robot 3 and the second robot 6 are both articulated robots, model Estun ER50-R2100-P, and the first robot 3 and the second robot 6 are provided with a visual recognition system and a product grasping system. The visual recognition system is an Omron 2D camera, and the product grasping system includes two sets of double-station disk-type grippers installed at the front end of the arms of the first robot 3 and the second robot 6, that is, the first robot 3 and the second robot 6 can grasp two workpieces to be processed at the same time, thereby saving time when switching processes.

[0024] In this embodiment, the first CNC lathe 1 and the second CNC lathe 2 are both TT200 CNC lathes, the flaw detector 7 is an eddy current flaw detector, the first robot 3 places the workpiece to be processed in the material temporary storage area 12 of the flaw detector 7, and the flaw detector 7 can be used to perform flaw detection on the workpiece to be processed. The cleaning machine 8 is an ultrasonic cleaning machine. After the flaw detection is completed, the second robot 6 places the workpiece to be processed in the cleaning machine 8 to clean the workpiece to be processed. The comparator 9 is a Renishaw comparator. After cleaning, the size of the workpiece to be processed is detected. The marking machine 10 is a laser marking machine, which performs marking processing on the workpiece to be processed.

[0025] When this embodiment is used, when turning is required, the first robot 3 grabs the workpiece to be processed on the first CNC lathe 1 and the second CNC lathe 2 to complete the operation. After the first robot 3 and the second robot 6 clamp the workpiece to be processed, they can put the workpiece to be processed into the designated CNC lathe according to work needs. After the CNC lathe clamps the workpiece to be processed, automatic turning can be performed. When flaw detection, cleaning, air blowing, size detection and marking are required, the second robot 6 grabs the workpiece to be processed and completes the operation on the flaw detector 7, the cleaning machine 8, the comparator 9, and the marking machine 10. If all the above operations are required, after turning is completed, the first robot 3 places the workpiece to be processed on the material temporary storage area 12, and the second robot 6 can perform subsequent operations.

[0026] In addition, an AGV trolley may be provided to automatically lift and move the product tray 13 to a designated position, so that when other operations need to be performed on the workpiece to be processed, the workpiece to be processed can be transferred before the AGV trolley is used.

[0027] Similarly, a transmission belt 14 may be provided downstream of the marking machine 10 . The transmission belt 14 is within the gripping range of the second robot 6 , and the processed workpiece may be directly transmitted to a subsequent process via the transmission belt 14 .

[0028] Taking the valve body valve seat of the hydraulic end of the plunger pump as an example, the main processes in the processing process are: rough turning, carburizing, normalizing, sandblasting, fine turning (including outer diameter, end face and conical surface), vulcanization process, rubber turning, flaw detection, cleaning, air blowing, marking, and size detection of parts. Among them, some processes can be processed in the same workshop, such as turning, flaw detection, cleaning, air blowing, marking, and size detection; while other processes need to be carried out in other workshops or specific occasions due to the characteristics of the process itself, such as carburizing process, normalizing process, sandblasting process, and vulcanization process. Therefore, in this embodiment, the process equipment that can be processed in the same workshop is centrally set up, and the process conversion and parts handling between each other are completed by the first robot 3 and the second robot 6; and the process that needs to be processed in other workshops or specific occasions, the transfer of products is realized by the AGV car.

[0029] Specifically, during operation, the AGV trolley delivers the workpiece to be processed to the first material buffer area 5 via the product pallet 13 in the entire line process, and then processes it through the first CNC lathe 1 and the second CNC lathe 2. That is, the first robot 3 visually identifies the position of the workpiece to be processed, and after the first robot 3 is guided by visual positioning to complete the grasping, it is sent to the first CNC lathe 1 for processing. The parts processed in a sequence are flipped through the flipping station 4 and then sent to the second CNC lathe 2 for processing. The processed parts are sent back to the product pallet 13 by the first robot 3 through the palletizing function. When a pallet of workpieces is processed, the first robot 3 sends a signal to the AGV trolley to change materials.

[0030] After the AGV trolley sends the processed workpiece into the first material buffer area 5, the workpiece is transported to the carburizing, normalizing and sandblasting workshops by the AGV trolley. After the workpiece is processed, it is transported back to the first material buffer area 5 by the AGV trolley. The first robot 3 visually identifies the position of the workpiece, and after the first robot 3 is guided by visual positioning to complete the grasping, it is sent to the first CNC lathe 1 and the second CNC lathe 2 for processing. The processed workpiece is returned to the product pallet 13 by the first robot 3 through the palletizing function. When a pallet of parts is processed, the first robot 3 sends a signal to the AGV trolley to change materials.

[0031] Finally, the AGV transports the workpiece to the vulcanization workshop. After processing, it is transported back to the first material buffer area 5 by the AGV. The first robot 3 visually identifies the material position. After the first robot 3 is guided by visual positioning to complete the grabbing, it is sent to the first CNC lathe 1 and the second CNC lathe 2 for processing. The processed workpiece is sent to the flaw detector 7 by the first robot 3 for flaw detection. The workpiece that passes the flaw detection is grabbed by the second robot 6 and sent to the cleaning machine 8 for cleaning and air blowing. The second robot 6 then grabs the workpiece and sends it to the comparator 9 for workpiece size detection. The workpiece that passes the size detection is sent to the marking machine 10 by the second robot 6 for marking. After marking, the material is unloaded and stacked to complete the processing of the entire process of the parts.

[0032] The present invention is used for the automated production line of annular parts, and adopts the method of a robot in cooperation with an AGV trolley to realize the conversion between different workstations in the product processing process, replacing manual work such as handling and clamping, thereby effectively improving production efficiency and shortening product production cycle.
