[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0027] Reference Figure 1-7, an automatic loading and unloading machine for tooling plates, comprising a frame 2, a stacking station 5 for stacking tooling plates, a tooling plate 8 placed on the stacking station 5, and a conveyor line 1 for conveying the tooling plate 8. A plate placing component 9 for lowering the tooling plate 8 is installed in the frame 2, and the plate placing component 9 is embedded in the line end of the conveyor line 1. A workpiece grabbing component 11 for grabbing and placing the tooling plate 8 is installed above the plate placing component 9. A moving frame 3 is provided on the outside of the workpiece grabbing component 11. A linear module 7 for driving the moving frame 3 to move is connected to the moving frame 3. The linear module 7 is connected and fixed to the frame 2 by a connecting frame 4, and a lifting component 10 is installed inside the plate placing component 9.

[0028] Through the functions of the workpiece grasping component 11, the plate placing component 9 and the lifting component 10, the lifting component 10 can directly remove the stacked tooling plates from the plate placing component 9 and quickly remove the plates in sequence, so that the tooling plates can circulate at high speed on the production line, thereby improving the overall production rhythm of the air-conditioning outdoor unit production line.

[0029] Specifically, the stacking station 5 is used to stack the tooling panels 8 to facilitate subsequent panel removal.

[0030] The plate placing component 9 includes a placing frame 901 , and a lifting component 10 is installed inside the placing frame 901 . The placing frame 901 has a U-shaped cross-section, and through openings 907 are provided on both sides of the inner wall of the placing frame 901 .

[0031] Furthermore, through the U-shaped structure arrangement of the placement rack 901, the conveyor line 1 is embedded in the U-groove set in the placement rack 901 and remains parallel to the jacking component 10 (not rising state), which facilitates the smooth completion of the cyclic board placement operation of the tooling plate. The through-openings 907 are distributed in at least four groups, which is convenient for providing hanging operations for the stacked tooling plates, and facilitates the subsequent continuous and efficient board unloading operations.

[0032] A supporting plate 902 is installed in the through hole 907 , the end of the supporting plate 902 is connected to a first connecting plate 903 , a second connecting plate 904 is installed below the first connecting plate 903 , and a first push plate cylinder 906 for pushing the first connecting plate 903 is installed on the second connecting plate 904 .

[0033] Furthermore, the cross-sectional shape of the carrier plate 902 is consistent with the shape of the through-opening 907, and a rubber pad is bonded to the outside of the carrier plate 902 to prevent the carrier plate 902 from scratching the tooling plate. The carrier plate 902 can be made of steel plate, which has strong bearing capacity and can be used to hang multiple tooling plates at one time. The first push plate cylinder 906 pushes the carrier plate 902 to move back and forth at the through-opening 907, which can provide a receiving operation for the stacked tooling plates and hang the stacked tooling plates on the line head of the conveyor line 1 to facilitate the unloading operation of the tooling plates.

[0034] A sliding assembly 905 is provided between the second connecting plate 904 and the first connecting plate 903 . The sliding assembly 905 includes a guide rail installed on the second connecting plate 904 and a slider connected to the first connecting plate 903 .

[0035] Furthermore, the first connecting plate 903 is pushed forward by the first push plate cylinder 906, driving the supporting plate 902 on the first connecting plate 903 to extend out in the through-opening 907, providing a supporting position for the stacked tooling plates, facilitating the lowering operation of the tooling plates, and the second connecting plate 904 and the first push plate cylinder 906 are fixedly connected by a mounting frame, so that the first push plate cylinder 906 can smoothly push or retreat the first connecting plate 903, so that the lowering operation of the tooling plates can be carried out smoothly.

[0036] The lifting component 10 includes a fixed plate 1003 installed on the plate placing component 9, and a lifting plate 1002 and a panel 1008 for placing the tooling plate 8 are sequentially arranged above the fixed plate 1003.

[0037] Furthermore, a gasket is arranged on the panel 1008 so that when the panel 1008 contacts the tooling plate 8, the tooling plate 8 is not easily moved on the panel 1008, thereby improving the stability of the tooling plate.

[0038] A screw rod 1004 passes through the lifting plate 1002 and the fixed plate 1003, and a threaded sleeve 1005 connected to the fixed plate 1003 is sleeved on the screw rod 1004. The lifting plate 1002 is equipped with a second transmission assembly 1001, and the driven wheel on the second transmission assembly 1001 is connected to the end of the screw rod 1004. The driving wheel on the second transmission assembly 1001 is equipped with a drive motor 1006 connected to the lifting plate 1002. Support rods 1007 connected to the bottom of the panel 1008 are arranged around the lifting plate 1002, and an in-position photoelectric sensor 1009 is installed on the fixed plate 1003.

[0039] Furthermore, the driving motor 1006 on the second transmission component 1001 works, so that the second transmission component 1001 drives the screw rod 1004 to rotate, so that the screw rod 1004 cooperates with the threaded sleeve 1005 at the bottom of the fixed plate 1003, so that the lifting plate 1002 and the panel 1008 move up and down, which is convenient for lowering the tooling plate. The in-place photoelectric sensor 1009 is used to judge and control the in-place status of the object, thereby triggering the control system to perform corresponding actions, such as stopping, turning or executing other preset program commands. The in-place photoelectric sensor 1009 is an existing mature technology and can be implemented using existing technology, which will not be elaborated here.

[0040] The workpiece grasping component 11 includes a frame 1106 installed in the movable frame 3. The frame 1106 is an inverted "U"-shaped structure. Connecting rods 1104 are provided on both sides of the frame 1106. The top of the connecting rod 1104 is connected to a first rotating block 1103, and the first rotating block 1103 is movably connected to a movable plate 1102.

[0041] Furthermore, the connecting rod 1104 and the first rotating block 1103 are fixedly connected, and the connection between the connecting rod 1104 and the frame 1106 is connected through a bearing, so that when the first rotating block 1103 is subjected to pushing and pulling forces, it can smoothly drive the second rotating block 1105 connected to the connecting rod 1104, thereby facilitating the grabbing of stacked tooling plates.

[0042] A second push plate cylinder 1101 for driving the moving plate 1102 is installed on the moving plate 1102 , and a second rotating block 1105 is installed at the bottom of the connecting rod 1104 .

[0043] Furthermore, the second push plate cylinder 1101 cooperates to push the movable plate 1102 and the first rotating block 1103 so that the second rotating block 1105 connected below the connecting rod 1104 is rotated out from the bottom of the frame 1106, thereby facilitating the grabbing operation of the stacked tooling panels 8.

[0044] The movable frame 3 is equipped with a lifting assembly 302 for sliding the frame 1106 up and down and a first transmission assembly 301 for driving the lifting assembly 302 to move. The lifting assembly 302 includes a threaded rod and a threaded slide that cooperates with the threaded rod. The threaded slide is connected to the frame 1106 to drive it to move up and down. The first transmission assembly 301 includes a main transmission wheel, a slave transmission wheel and a transmission chain. The slave transmission wheel is installed on the threaded rod of the lifting assembly 302.

[0045] Furthermore, the workpiece grabbing component 11 is driven by the lifting assembly 302 on the movable frame 3, so as to facilitate the handling and transfer operations of the stacked tooling plates, and has high practicality.

[0046] A safety grid plate 6 is installed on the frame 2 , and the safety grid plate 6 is distributed in two groups, front and back. A tooling plate 8 is placed on the stacking station 5 .

[0047] Furthermore, by providing the safety grid 6, safety protection can be provided for the circulating lowering of the tooling plate at the thread head of the conveyor line 1, thereby ensuring the safety of the operators.

[0048] Equipment working process: through the first transmission component 301 and the lifting component 302, the workpiece grabbing component 11 is driven to move downward, so that the workpiece grabbing component 11 is moved down to the stacking station 5, and the second push plate cylinder 1101 cooperates to push the movable plate 1102 and the first rotating block 1103 to make the second rotating block 1105 connected to the lower part of the connecting rod 1104 rotate out from the bottom of the frame 1106, so as to facilitate the grabbing operation of the stacked tooling panels 8. Then, the linear module 7 drives the workpiece grabbing component 11 on the movable frame 3 to move horizontally toward the plate placing component 9, and lowers the tooling panel 8 to the supporting plate 902 of the plate placing component 9. When the tooling panel 8 is lowered, the lifting component 10 is lifted to make the panel 1008 contact the last tooling panel 8 on the supporting plate 902. At the same time, the supporting plate 902 cooperates with the first push plate cylinder 906 to retreat into the through-port 907, and the lifting component 10 drops to the height of one tooling plate 8, and then moves the four groups of supporting plates 902 forward to hang the tooling plates 8 that have not been lowered and stacked above. Then, the lifting component 10 continues to drop until the tooling plate is placed on the conveyor line 1, completing the tooling plate 8 lowering action. Through the integrated workpiece grabbing component 11, the plate placing component 9 and the lifting component 10, the lifting component 10 can directly remove the stacked tooling plates from the plate placing component 9 quickly in turn, so that the tooling plates can circulate at high speed on the production line, so that the overall production rhythm of the air-conditioning outdoor unit production line in the embodiment is increased from 12S per unit to 7.5S per unit, which speeds up the production efficiency of the product. The device setting has the advantages of high speed, stability and flat plate placement.

[0049] To sum up, 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.
