Traditional processing methods usually process the metal workpiece 10 from the upper side, and change the processing surface by changing the fixture or process different processing surfaces by multi-axis processing equipment.

[0032] Please continue reading Figures 3 to 6 As shown, the metal workpiece processing equipment of the present application includes a workpiece processing table 20 , a loading and unloading assembly 40 disposed on a first lateral side of the workpiece processing table 20 , and a processing machine table 30 disposed on a second lateral side of the workpiece processing table 20 .

[0033] The workpiece processing table 20 includes a base 21, a pressure spraying assembly 22 mounted on both lateral sides of the base, a rotating mechanism 23 fixed to both longitudinal ends of the base 21, a fixed beam 233 mounted above the base 21 and fixed to the rotating mechanism 23 at both ends, a drainage port 25 for draining outward from one longitudinal side of the base 21, and a waste liquid tank 24 placed below the drainage port 25.

[0035] The drainage groove 212 includes a first end 2121 with a wider transverse width and a second end 2122 with a narrower transverse width. The drainage groove 212 is concave to prevent waste liquid from overflowing. The narrower second end 2122 is connected to a drainage port 25, and there is only a waste liquid tank 24 below the drainage port 25. Wastewater in the drainage groove 212 flows into the waste liquid tank 24 for collection and treatment.

[0036] The rotating mechanism 23 includes a clamping plate 231 fixed to the longitudinal ends of the table 215, a rotating wheel 232 fixed to the inner side of a pair of clamping plates 231, a fixed beam 233 with two ends respectively fixed to the rotating wheel 232, and a clamp 234 provided on the four surfaces of the fixed beam 233. The fixed beam 233 is in the shape of a rectangular parallelepiped and includes four side surfaces. The clamps 234 are respectively fixed on the four side surfaces. The clamps 234 on the four side surfaces of the fixed beam 233 constitute the first, second, third, and fourth workstations L2, L2, L3, and L4. The rotating wheel 232 rotates 90 degrees each time to fix the relative positions of the four workstations. The fixed beam 233 is located above the drainage groove 212. Among the four surfaces of the fixed beam 233, the one close to the loading and unloading assembly 40 is the first workstation L1, the one close to the processing machine 30 is the third workstation L3, and the upper and lower surfaces of the fixed beam 233 correspond to the second and fourth workstations L2 and L4, respectively.

[0037] A plurality of pressure spraying assemblies 22 facing the fourth station L4 are installed on the side fixing parts 214 on both sides of the table 215. The pressure spraying assemblies 22 include a plurality of liquid nozzles 221 and a plurality of air nozzles 222. Both the liquid nozzles 221 and the air nozzles 222 are directed toward the metal workpiece 10 on the fourth station L4 to clean and air-dry the processed metal workpiece 10, mainly to clean impurities such as metal debris.

[0038] The loading and unloading assembly 40 includes a robot fixing seat 41 located on a lateral side of the workpiece processing table 20, a loading platform 42 and an unloading platform 43 arranged on both sides of the longitudinal direction of the robot fixing seat 41, a robot 44 fixed on the robot fixing seat 41, and a clamp 45 fixed on the robot 44.

[0039] The loading platform 42 and the unloading platform 43 respectively include a bracket 421 and a loading area 422 formed on the upper surface of the bracket 421. The loading area 422 is set as an inclined surface, including a higher high-level area 423 and a lower low-level area 424. The low-level area 424 and the two lateral sides protrude upward to form a closed structure, and the high-level area 423 is an open structure. The loading platform 42 and the unloading platform 43 are placed on both sides of the manipulator 44 in the same direction, wherein the low-level area 424 of the loading platform 42 is close to the manipulator 44, and the high-level area 423 of the unloading platform 43 is close to the manipulator 44. The clamping claw 45 of the manipulator 44 clamps the metal workpiece 10 from the low-level area 424 of the loading platform 42 and installs it on the first station L1. The metal workpiece 10 in the high-level area 423 automatically slides down to the low-level area 424 under the action of gravity. The metal workpiece 10 can be continuously placed in the high-level area 423 of the loading platform 42 by personnel or an automated assembly line. After the processed metal workpiece 10 is taken from the first station L1 by the manipulator and placed in the high-level area 423 of the unloading platform 43, the metal workpiece 10 automatically slides down from the high-level area 423 to the low-level area 424, and the processed metal workpiece 10 is taken away in the low-level area 424.

[0040] The processing machine 30 is located at the second transverse side of the workpiece processing table 20, and the processing machine 30 includes a fixed table 31 fixed to the base 21 as a whole, a longitudinal slider 32 that can slide longitudinally on the fixed table 31, a transverse slider 33 that can slide transversely on the longitudinal slider 32, and a tool assembly 34 fixed on the transverse slider 33 and can slide in the up and down direction. A first slide rail 311 is provided on the upper surface of the fixed table 31, a second slide rail 321 is provided on the upper surface of the longitudinal slider 32, and a third slide rail 331 is provided on a longitudinal side surface of the transverse slider 33. The longitudinal slider 32 slides longitudinally on the first slide rail 311, the transverse slider 33 slides transversely on the second slide rail 321, and the tool assembly 34 slides vertically on the third slide rail 331. The tool assembly 34 includes a driving mechanism 341, a tool handle clamping portion 342 located at one transverse end of the driving mechanism 341, and a tool 343 clamped on the tool handle clamping portion 342. The tool 343 faces the third workstation L3 of the workpiece processing table 20 .

[0041] The operating principle of the metal workpiece processing equipment of the present application for processing the metal workpiece is as follows: first, the robot 44 grabs the unprocessed metal workpiece 10 from the loading table 42 and fixes it on the first station L1 on the workpiece processing table 20, and then the rotating mechanism 23 rotates 90 degrees to rotate the first station L1 to the second station L2. At this time, the processing machine 30 starts to process the metal workpiece 10. At the same time, the robot 44 takes out the metal workpiece 10 that has been processed at the fourth station L4 and rotates to the first station L1, and re-clamps an unprocessed metal workpiece 10 to the first station L1. During this process, the tool assembly simultaneously processes the metal workpieces 10 on the second, third, and fourth stations L2, L3, and L4. The processing positions are respectively the first lateral side 12 of the metal workpiece 10 on the second station L2, the upper surface 13 of the metal workpiece 10 on the third station L3, and the second lateral side 12 of the metal workpiece 10 on the fourth station L4. In this way, the processing of the three surfaces of the metal workpiece 10 is completed at the second to fourth workstations, and the processing machine 30 only needs to stop and wait, and can continue processing according to the set program, which greatly improves the processing efficiency.

[0042] The processing path of the tool 343 is preferably to process from the second station L2 to the fourth station L2 for the first time, and then to process from the fourth station L4 to the second station L2 for the second time, and this cycle is repeated, which can reduce the position adjustment of the processing machine 30. At the same time, the metal workpiece 10 on the fourth station L4 will be cleaned by the pressure spraying assembly 22 through liquid and gas, and the waste liquid and waste residue generated by the cleaning will fall into the drainage groove 212 and finally flow into the waste liquid tank 24.

[0043] The metal workpiece processing equipment of the present application is provided with a rotatable fixed beam 233 on the workpiece processing table 20, and the four sides of the fixed beam 233 are respectively provided with clamps for clamping the metal workpiece 10 to form four workstations L1-L4. The fixed beam 233 is rotated 90 degrees each time, and the tool 343 placed on the lateral side of the workpiece processing table 20 is used to continuously process the different processing surfaces of the three metal workpieces 10 at the three workstations L2-L4, thereby completing the processing of the three surfaces of the metal workpiece 10 without stopping the machine, greatly improving the efficiency. At the same time, there is no need to change the clamp, which improves the processing accuracy.

[0044] The method for processing a metal workpiece 10 of the present application comprises the following steps:

[0045] S10, conveying the unprocessed metal workpiece 10 to the first workstation L1 of the workpiece processing table 20 by the robot 44;

[0046] This step also includes taking the processed metal workpiece 10 from the first workstation L1 by the robot 44 and then transporting the unprocessed metal workpiece 10 to the workstation L1.

[0047] S20, the fixed beam 233 of the workpiece processing table 20 rotates 90 degrees, the metal workpiece on the first station L1 rotates to the second station L2, and so on, the metal workpiece 10 on the fourth station L4 rotates to the first station L1, and at the same time, the processing machine 30 is started to process different surfaces of the metal workpieces 10 on the second to fourth stations L2-L4;

[0048] This step includes a process of continuous full-turn processing, that is, in the first step, the machine is started, the manipulator 44 loads the material, the fixed beam 233 rotates 90 degrees, and the tool 343 starts to process the first lateral side 12 of the metal workpiece 10 on the second station L2; in the second step, after the first lateral side 12 of the metal workpiece 10 at the second station L2 is processed, the fixed beam 233 rotates 90 degrees again, and at the same time, the manipulator loads the material. At this time, the tool 343 processes the first lateral side 12 of the metal workpiece 10 at the second station L2 and the upper surface 13 of the metal workpiece 10 at the third station L3; in the third step, the fixed beam 233 rotates 90 degrees again, the manipulator loads the material, and the tool 343 processes the metal workpiece at the second station L2. The first lateral side 12 of the metal workpiece 10, the upper surface of the metal workpiece 10 on the third station L3 and the second lateral side 12 of the metal workpiece 10 on the fourth station L4 are processed. After the processing is completed, the metal workpiece 10 on the fourth station L4 has been processed at the second station L2, the third station L3 and the fourth station L4 respectively, that is, at this time, the three sides of the metal workpiece 10 on the fourth station L4 have been processed, and at the same time, the pressure spraying assembly 22 cleans and dries the metal workpiece 10 on the fourth station L4; in the fourth step, the fixed beam 233 rotates 90 degrees again, the robot 4 first removes the metal workpiece 10 processed on the first station L1 and then loads it, and the tool 343 repeats the processing path in the third step for processing, and the processing is repeated continuously.

[0049] The processing path of the tool 343 can be from the second station L2 to the fourth station L4, and then from the fourth station L4 to the second station L2; or it can always be processed from the second station L2 to the fourth station L4, but this path may waste the time of the tool moving position and reduce efficiency. The time of the tool moving can also be used to start the pressure spray component 22 to clean the metal workpiece 10 on the fourth station L4; or it can always be processed from the fourth station L4 to the second station L2. This path first processes the metal workpiece 10 on the fourth station L4, and then processes the metal workpiece 10 on the third and second stations L3, L2. The time of processing the third and second stations L3, L2 can be used to start the pressure spray component 22 to clean the metal workpiece 10 on the fourth station L4.

[0050] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for those of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
