Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, and in particular to a robotic arm for automatic laser cutting of aluminum foil. Background Technology

[0002] Aluminum foil is a thin sheet material made by directly rolling metallic aluminum. Due to its excellent physical and chemical properties, it is widely used in various fields. To handle the cutting of complex shapes and fine structures to meet the needs of electronic product manufacturing, laser cutting is usually used to cut aluminum foil. During cutting, the aluminum foil is first laid flat and fixed on the worktable, and then the laser cutting device cuts the aluminum foil into the required shape and pattern.

[0003] However, the following problems exist in the current process of cutting and processing aluminum foil: 1. Aluminum foil is a thin and soft material, prone to wrinkles or unevenness. If the aluminum foil is not sufficiently smoothed and fixed, it will move or deform during the cutting process, leading to decreased cutting accuracy and increasing the possibility of defective products. 2. Uneven aluminum foil can also cause uneven energy absorption in local areas when exposed to laser irradiation, thus affecting the quality of the cut edge. 3. Existing cutting equipment can only cut and form one aluminum foil product at a time, resulting in low overall processing efficiency. Summary of the Invention

Detailed Implementation

[0031] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] like Figure 1 and Figure 2 As shown, a robotic arm for automatic laser cutting of aluminum foil includes a rectangular frame 10 and a fixing plate 11 fixedly mounted on the robotic arm; a smoothing mechanism 2 is provided on the rectangular frame 10, the fixing plate 11 is installed inside the rectangular frame 10 through a limiting mechanism 3, and a cutting mechanism 4 is provided on the fixing plate 11; it should be noted that the robotic arm is prior art, and its specific structure is not shown in the figure.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, the smoothing mechanism 2 includes a rectangular tube 20. The rectangular tube 20 is fixedly installed at the lower end of the rectangular frame 10. Two symmetrical connecting rods are rotatably installed at both ends of the rectangular tube 20 via torsion spring rods. A roller 21 for rolling and smoothing aluminum foil is rotatably installed between the two front-to-back connecting rods. Two symmetrical rubber pads are fixedly installed at the lower end of the rectangular tube 20. Holes and slots are evenly opened from left to right at the positions corresponding to the rubber pads at the lower end of the rectangular tube 20. The holes and slots pass through the corresponding rubber pads. Suction cups 22 are fixedly installed in the holes and slots. A channel 23 is opened in the rectangular tube 20 that communicates with all the holes and slots.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the lower end of the rectangular frame 10, located inside the rectangular tube 20, is provided with a pressing part 24 for fixing and maintaining the smoothed aluminum foil in multiple segments. The rectangular frame 10 and the rectangular tube 20 are both provided with a fixing part 25 for fixing the fixing plate 11. The rectangular tube 20 is provided with a connecting part 26 for cooperating with the fixing part 25 to fix the pressing part 24 and a suction and release part 27 for controlling the suction and release of the suction cup 22. The pressing part 24 includes a rectangular frame plate 240, and multiple rectangular frame plates 240 are evenly arranged from left to right inside the rectangular tube 20.

[0035] In actual operation, the feeding mechanism installed on the left side of the existing workbench drives the aluminum foil roll to rotate and release the aluminum foil, while the winding mechanism on the right side of the workbench rewinds the released aluminum foil to achieve continuous feeding processing. Then, the robotic arm drives the automatic laser cutting device for aluminum foil to move towards the aluminum foil on the workbench, so that the roller 21 first contacts the aluminum foil and presses it against the workbench to make it fit. At the same time, the aluminum foil is rolled and tightened to flatten it. Then, as the rectangular frame 10 and the rectangular tube 20 continue to move downward, the pressing part 24 will press against the flattening part. The flattened aluminum foil is divided into multiple sections and pressed down to fix it, so as to keep the aluminum foil in a smooth state. At the same time, the suction cup 22 is attached to the worktable. Then, the fixing part 25 releases the fixing plate 11, and the suction cup 22 is attached to the worktable by the extraction part 27 to fix the rectangular tube 20 and the rectangular frame 10 to the worktable. Furthermore, the fixing part 25 also connects and limits the rectangular frame plate 240 to the rectangular tube 20 through the connecting part 26 to improve the stability of the rectangular frame plate 240, thereby improving the accuracy of aluminum foil cutting.

[0036] like Figure 2 , Figure 4 and Figure 5 As shown, the lower end of the rectangular frame plate 240 is fixedly installed with rubber pads of No. 2, and the upper end of the rectangular frame plate 240 is installed with four rectangularly distributed support rods 241. The lower end of the rectangular frame 10 is provided with round holes at positions corresponding to the support rods 241. The upper end of the support rod 241 slides through the corresponding round hole. The round hole is provided with a pre-fixing component for pre-fixing the support rod 241 to the rectangular frame 10. The rectangular frame 10 is provided with locking parts 5 for fixing the rectangular frame plate 240 in sequence.

[0037] like Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the pre-fixed component includes a sliding groove. The inner wall of the circular hole is uniformly provided with a sliding groove along its circumference. A ball bearing 243 is slidably installed in the sliding groove in cooperation with a second compression spring 242. The outer wall of the support rod 241 is provided with annular grooves along its circumference that cooperate with the ball bearing 243 one by one.

[0038] like Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the locking component 5 includes a pushing block 50. The pushing block 50 is slidably installed on the upper horizontal section of the rectangular frame 10 between two adjacent support columns on two adjacent rectangular frame plates 240. The lower right part of the pushing block 50 has an inclined surface sloping downwards and to the left. The support rod 241 has a ramp that matches the inclined surface of the pushing block 50. A vertical plate is fixedly installed on the upper horizontal section of the rectangular frame 10 to the left of the pushing block 50. The left end of the pushing block 50 is fixedly installed... There is a first locking rod 51. The left end of the first locking rod 51 slides through the corresponding upright plate and into the adjacent support rod 241. A first compression spring 52 is fixedly installed between the push block 50 and the upright plate and sleeved on the first locking rod 51. A first connecting plate 54 is installed on the right end of the rectangular frame 10 through a tension spring 53. A second locking rod 55 is fixedly installed between the two front and rear support rods 241 on the far right side of the left end of the first connecting plate 54. The left end of the second locking rod 55 slides through the rectangular frame 10 and the corresponding support rod 241.

[0039] In practice, the leftmost rectangular frame plate 240 is manually installed inside the rectangular tube 20, and the support rod 241 is inserted into the corresponding circular hole. During insertion, the upper end of the support rod 241 will abut against the ball bearing 243, pushing the ball bearing 243 away from the support rod 241 and compressing the first compression spring 52, until the annular groove on the support rod 241 aligns with the ball bearing 243. At this point, the ball bearing 243 is pushed into the corresponding annular groove under the action of the first compression spring 52, thus pre-limiting the movement of the support rod 241 and pre-fixing the rectangular frame plate 240. Then, the next rectangular frame plate 240 is installed to the right. The support rod 241 on this rectangular frame plate 240 is inserted into the circular hole and pre-fixed by the pre-fixing component. At the same time, it will also push the pusher block 50 to move obliquely to the left, and the pusher block 50 will drive the corresponding ball bearing 243 to move obliquely to the left. Locking rod 51 is inserted into the corresponding support rod 241 on the previous rectangular frame plate 240 to restrict the movement of the previous rectangular frame plate 240. When installing the last (i.e., the rightmost) rectangular frame plate 240, the first connecting plate 54 is manually pulled away from the rectangular frame 10 while the tension spring 53 is stretched. The first connecting plate 54 then drives the second locking rod 55 to move to avoid interfering with the installation of the rectangular frame plate 240. After the support rod 241 on the last rectangular frame plate 240 is inserted into the round hole and pre-fixed by the pre-fixing component, the first connecting plate 54 is released. Under the action of the tension spring 53, the first connecting plate 54 drives the corresponding second locking rod 55 to be inserted into the corresponding support rod 241, thereby restricting the movement of the rectangular frame plates 240 in sequence to ensure that the rectangular frame plates 240 as a whole remain stable during the cutting process.

[0040] like Figure 1 , Figure 4 , Figure 5 and Figure 8 As shown, the limiting mechanism 3 includes a limiting rod 30. The limiting rod 30 is rotatably installed in the middle of the four end faces of the fixed plate 11. The four vertical sections of the rectangular frame 10 are provided with square holes 31 at the positions corresponding to the limiting rod 30. The limiting block 32 is rotatably installed in the square hole 31 through the shaft column. The end of the limiting rod 30 away from the fixed plate 11 slides through the corresponding limiting block 32.

[0041] like Figure 1 , Figure 4 , Figure 5 and Figure 8 As shown, the fixing part 25 includes a U-shaped plate 250. The U-shaped plate 250 is slidably installed on the front end of the rectangular frame 10. The upper ends of the two vertical sections of the U-shaped plate 250 are fixedly installed with support plates 251 located above the rectangular frame 10. The lower end of the support plate 251 is fixedly installed with a plug rod 252. The upper end of the fixing plate 11 is provided with a plug hole 253 corresponding to the plug rod 252. The front end of the rectangular tube 20 is fixedly installed with an electric push rod 254 whose telescopic section is fixedly connected to the U-shaped plate 250.

[0042] like Figure 2 , Figure 4 and Figure 5 As shown, the cutting mechanism 4 includes a laser cutting component 40. The laser cutting component 40 is fixedly installed at the lower end of the fixed plate 11 and at the position corresponding to the rectangular frame plate 240. A rectangular hole 41 is opened in the horizontal section of the rectangular frame 10, and the lower end of the laser cutting component 40 moves through the rectangular hole 41.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 8 As shown, the extraction and dispensing part 27 includes a sleeve 270. The front end of the rectangular tube 20 is fixedly installed with a sleeve 270 that communicates with the channel 23. A piston 271 is slidably installed inside the sleeve 270. A push plate 272 is fixedly installed on the upper end of the piston 271. The upper end of the push plate 272 is fixedly connected to the U-shaped plate 250 through a second connecting plate 273.

[0044] In actual operation, after the suction cup 22 is attached to the worktable, the electric push rod 254 pushes the U-shaped plate 250 to move upward. The U-shaped plate 250 then drives the insertion rod 252 away from the insertion hole 253 through the support plate 251, so as to release the limitation on the fixed plate 11. Then the robotic arm drives the fixed plate 11 to move within the frame of the rectangular frame plate 240 to cut aluminum foil of the required size and pattern. The upward movement of the U-shaped plate 250 will also push the piston 271 upward through the first connecting plate 54 and the push plate 272 to suck up the air in the sleeve 270 and the channel 23, so that the suction cup 22 is attached to the worktable. In addition, the upward movement of the U-shaped plate 250 will also drive the connecting part 26 to connect the rectangular frame plate 240 with the rectangular tube 20, so as to further improve the stability of the rectangular frame plate 240.

[0045] After the cutting is completed, the fixed plate 11 is reset to the initial position of the cutting movement. The electric push rod 254 pulls the U-shaped plate 250 downward and drives the insertion rod 252 to insert into the insertion hole 253 to restrict the movement of the fixed plate 11, thereby ensuring the stability of the movement of the robotic arm through the fixed plate 11 to drive the rectangular frame 10. The downward movement of the U-shaped plate 250 will also release the suction cup 22 from the adsorption of the worktable and the fixing of the connecting part 26 to the rectangular frame plate 240.

[0046] like Figure 1 and Figure 8As shown, the connecting part 26 includes a limiting component. The front end of the rectangular tube 20 is provided with a limiting component that corresponds one-to-one with the rectangular frame plate 240. Each limiting component consists of two left and right symmetrical shafts 260. The rear end of the shaft 260 slides through the rectangular tube 20 and the corresponding rectangular frame plate 240. The front end of the shaft 260 is fixedly installed with a connecting plate 261. The connecting plate 261 and the U-shaped plate 250 are both provided with a driving component 6 for driving the shaft 260 to move.

[0047] like Figure 1 , Figure 2 and Figure 8 As shown, the driving component 6 includes a rectangular plate. Two rectangular plates that are symmetrically arranged on the left and right sides are fixedly installed at the rear end of the connecting plate 261. The rectangular plates are provided with inclined grooves 60 that are inclined upward at the front end. Push-pull plates 61 that are fixedly installed on the U-shaped plate 250 are provided at the opposite ends of the two rectangular plates. Guide posts 62 that slide through the corresponding inclined grooves 60 are fixedly installed on the opposite surfaces of the two push-pull plates 61.

[0048] In actual operation, the upward movement of the U-shaped plate 250 also drives the push-pull plate 61 to move upward. The push-pull plate 61, through the cooperation of the guide post 62 and the inclined groove 60, drives the connecting plate 261 to move towards the rectangular tube 20 via the rectangular plate. At the same time, it drives the shaft 260 to pass through the rectangular tube 20 and insert into the corresponding rectangular frame plate 240, so that the rectangular frame plates 240 and the rectangular tube 20 are combined into a whole, so as to ensure the stability of the rectangular frame plate 240 during the cutting process, avoid the movement of the rectangular frame plate 240 from affecting the flatness of the aluminum foil, and thus ensure the quality of aluminum foil cutting. After the cutting is completed, the electric push rod 254 pulls the U-shaped plate 250 downward. With the cooperation of the guide post 62 and the inclined groove 60, the connecting plate 261 drives the shaft 260 to move and disengage from the rectangular frame plate 240, so that the rectangular frame plate 240 can be quickly disassembled and maintained when not cutting.
