[0038] In order to make the objectives, technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0039] like Figure 1-14 As shown, an automatic loading and unloading device for a CNC drilling and milling machining center includes a loading material cart 1, an articulated robot mechanism 2, a secondary positioning mechanism 3, a CNC drilling and milling machining center 4, a unloading material cart 5, and a control system 6.

[0040] Manually push the loading material cart 1 with the profile to be processed to the guide block 12, so that the front caster A11 of the loading material cart 1 moves forward along the guide block 12, and push the positioning pin 9 of the loading material cart 1 along the guide block 12 to enter the positioning plate 8, so that the positioning pin 9 is pushed into the innermost position of the positioning plate 8 and cannot be pushed, and the caster A11 at the rear end of the loading material cart 1 is braked to fix the loading material cart 1. After positioning the loading material cart 1, wait for the joint robot mechanism 2 to grab the profile to be processed. Each material cart is equipped with a radio frequency card 21, and the radio frequency card 21 records the information of the material cart model and profile.

[0041] The joint robot mechanism 2 grabs the profile according to the signal of the control system 6 and puts the profile on the workbench of the secondary positioning mechanism 3. The profile clamping device of the joint robot mechanism 2 moves to the position of the profile to be grabbed, and the profile clamping plate clamping cylinder 37 is ventilated to drive the fixed clamping plate 32 and the movable clamping plate 34 to move along the guide rail C30 through the slider C31 to clamp the profile. After clamping the profile, the fixed clamping plate 32 and the movable clamping plate 34 are both in a free state. The clamping device of the joint robot mechanism 2 moves away from the fixed block 15, the fixed block 2 16, the fixed block 3 17, and the fixed block 4 18. The positioning cylinder 39 drives the fixed clamping plate 32 to move to the positioning block 41 through the positioning cylinder long rod 40. At this time, the fixed clamping plate 32 and the movable clamping plate 34 are in a fixed state. The robot mechanism 2 controls the control system 6 to put the profile on the workbench of the secondary positioning mechanism 3. The radio frequency card reader 42 reads the material vehicle and profile information in the radio frequency card 21 on the material vehicle through the control system 6, and then transmits it to the control system 6. The radio frequency card reader 42 of the articulated robot mechanism 2 is connected to the control system 6 .

[0042] After the secondary positioning mechanism 3 receives the profile information read by the radio frequency card reader 42 transmitted by the control system 6, the servo motor 65 starts to work. The servo motor 65 drives the synchronous pulley A67, the synchronous wheel B66 and the synchronous belt 68 transmission device through the reducer 64 to rotate and drive the support plate 47 to carry the right workbench through the slider A46 and move along the guide rail A45 to the corresponding position. After the right workbench is in place, the articulated robot mechanism 3 places the two ends of the profile grabbed from the loading profile material vehicle 1 on the left workbench plate 51 and the right workbench plate 56 respectively. After placing the profile, the clamping device of the articulated robot mechanism 2 is released and the clamping device of the articulated robot mechanism 2 is removed. The right workbench moving cylinder 61 pushes the right workbench plate 56 through the slider D49 to move along the guide rail D48 until the photoelectric switch 1 55 and the photoelectric switch 2 60 both sense the signal and then stop moving. The clamping device of the articulated robot mechanism 2 moves to the position of the profile to be grasped, and the profile clamping plate clamping cylinder 37 ventilates to drive the fixed clamping plate 32 and the movable clamping plate 34 to move along the guide rail C30 through the slider C31 to clamp the profile. After clamping the profile, the fixed clamping plate 32 and the movable clamping plate 34 are both in a free state. The right workbench moving cylinder 61 pushes the right workbench plate 56 through the slider D49 to move along the guide rail D48 to release the clamped profile. The clamping device of the articulated robot mechanism 2 moves away from the secondary positioning workbench, and the positioning cylinder 39 drives the fixed clamping plate 32 to move to the positioning block 41 through the positioning cylinder long rod 40. At this time, the fixed clamping plate 32 and the movable clamping plate 34 are in a fixed state. The robot mechanism 2 is controlled by the control system 6 to place the profile on the workbench of the CNC drilling and milling processing center 4. The servo motor 65, the right workbench moving cylinder 61, the photoelectric switch 1 55, and the photoelectric switch 2 60 are connected to the control system 6.

[0043] After the CNC drilling and milling machining center 4 receives the profile information read by the radio frequency card reader 42 transmitted by the control system 6, the CNC drilling and milling machining center 4 automatically retrieves the corresponding machining program from the control system 6, waits for the joint robot mechanism 2 to put the profile to be processed on the workbench of the CNC drilling and milling machining center 4, the clamping device of the joint robot mechanism 2 moves away, and the CNC drilling and milling machining center 4 starts to process the profile. After the profile processing is completed, the joint robot mechanism 2 moves the clamping device to the position of the profile to be grasped, and the profile clamping plate clamping cylinder 37 is ventilated to drive the fixed clamping plate 32 and the movable clamping plate 34 to move along the guide rail C30 through the slider C31 to clamp the profile. After clamping the profile, the fixed clamping plate 32 and the movable clamping plate 34 are in a free state. The clamping device of the robot mechanism 2 moves away from the workbench, and the positioning cylinder 39 drives the fixed clamping plate 32 to move to the positioning block 41 through the positioning cylinder long rod 40. At this time, the fixed clamping plate 32 and the movable clamping plate 34 are in a fixed state. The articulated robot mechanism 2 places the processed profiles onto the unloading material vehicle 6 through the control system 6 .

[0044] Manually push the empty unloading material cart 6 to the guide block 12, so that the front caster A11 of the unloading material cart moves forward along the guide block 12, and push the positioning pin 9 of the unloading material cart 6 along the guide block 12 into the positioning plate 8, so that the positioning pin 9 is pushed into the innermost position of the positioning plate 8 where it cannot be pushed, and brake the caster A11 at the rear end of the unloading material cart 1 to fix the unloading material cart 6. After positioning the unloading material vehicle 6, the articulated robot mechanism 2 places the grabbed profile into the profile fixing block 1 15, the fixing block 2 16, the fixing block 3 17, and the fixing block 4 18. When the profile is about to be placed into the bottom end of the profile fixing block 4 18, the clamping device is loosened, and the profile automatically falls along the fixing block 1 15, the fixing block 2 16, the fixing block 3 17, and the fixing block 4 18, and instantly contacts with the profile fixing block 5 22. The profile is fixed by the interaction of the profile fixing block 1 15, the fixing block 2 16, the fixing block 3 17, the fixing block 4 18, and the fixing block 5 22. If it is a frame material, when the profile automatically falls, it instantly contacts with the fixing block 5 22 and the stopper 23, and the profile is fixed by the interaction of the stopper 23, the fixing block 1 15, the fixing block 2 16, the fixing block 3 17, the fixing block 4 18, and the fixing block 5 22. The fixing block 15, the fixing block 2, the fixing block 3, the fixing block 4, the fixing block 18 are tilted at a certain angle in two directions to control the skewing of the profile, especially the Z-shaped fan material. The fixing block 15, the fixing block 2, the fixing block 3, the fixing block 17, the fixing block 4, the fixing block 18 are tilted at a certain angle in two directions to solve the problem that the Z-shaped fan material is easy to be skewing and falling, which has not been solved in the industry. Each profile vehicle is equipped with a radio frequency card 21, which records the information of the profile vehicle model and profile.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
