DETAILED DESCRIPTION

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, an automatic deburring device for an aluminum box of an LED display screen includes a box 4 and a robotic arm 2, the end of which is provided with a deburring component 1:

[0026] The deburring assembly 1 comprises:

[0027] A rounded roller 111 sliding in the horizontal direction;

[0028] An adjustable grinding roller 13 is arranged to slide in the vertical direction and has an adjustable deflection angle, and has a lowest point that abuts against the edge of the box body 4;

[0029] The rounded roller 111 moves closer to the box body 4 , and the adjustable grinding roller 13 moves upward and separates from the box body 4 .

[0030] Specifically, the rounded corner roller 111 and the adjustable grinding roller 13 are respectively provided with a first motor 112 and a second motor 131 for driving. It also includes a telescopic rod for pushing the rounded corner roller 111 toward the box body 4. In the default state, the adjustable grinding roller 13 is located at the lowest point, and the adjustable grinding roller 13 is driven to rotate, and then the adjustable grinding roller 13 is driven by the robot arm 2 to move, and the beveled chamfered parts of the edge of the box body 4 are polished and deburred. When the edge of the box body 4 is an arc-shaped chamfer, the rounded corner roller 111 is driven to approach the box body 4, and the rounded corner roller 111 is driven to rotate. The rounded corner roller 111 is close to the arc-shaped chamfer and polished, thereby achieving targeted polishing and deburring operations on the edges of different boxes 4.

[0031] Furthermore, the adjustable grinding roller 13 can be assembled on a hydraulic rod, and a preset program can be set so that when the rounded corner roller 111 approaches the box body 4, a signal is sent to the hydraulic rod, and the adjustable grinding roller 13 is driven upward by the hydraulic rod, or a cable is set on the adjustable grinding roller 13, and when the rounded corner roller 111 approaches the box body 4, the cable is pulled, and the adjustable grinding roller 13 is driven upward by the cable, or other linkage mechanisms known to those skilled in the art can be used.

[0032] In the above technology, the adjustable grinding roller 13 is driven to grind and remove burrs on the beveled chamfered parts of the edge of the box body 4. When the arc chamfer needs to be polished, the rounded corner roller 111 is driven to approach the box body 4. At this time, the adjustable grinding roller 13 moves up to avoid interference. The rounded corner roller 111 approaches the arc chamfer and polishes it, thereby achieving targeted grinding and deburring operations on the edges of different box bodies 4.

[0033] As an embodiment further provided by the present invention, it also includes a mounting base 21 arranged at the end of the robotic arm 2, on which a sliding block 11 is slidingly arranged to keep synchronous movement with the adjustable grinding roller 13, and the rounded corner roller 111 is rotatably arranged on the sliding block 11.

[0034] Specifically, the machine also includes a transmission rod 12 slidably mounted on the mounting base 21, and an adjustable grinding roller 13 is mounted on the transmission rod 12. The transmission rod 12 and the sliding block 11 are in sliding engagement. When the sliding block 11 approaches the housing 4, the sliding block 11 pushes the transmission rod 12 upward, thereby causing the adjustable grinding roller 13 to stagger with the fillet roller 111 to avoid interference.

[0035] As another embodiment further provided by the present invention, it also includes a limit seat 15, on which a fixed rod 14 is rotatably provided, and the adjustable grinding roller 13 is rotatably provided on the fixed rod 14, and a pin 18 for pressing the limit seat 15 is provided on the fixed rod 14.

[0036] Specifically, a spring 19 is provided on the latch 18 to keep the latch 18 extending outward from the fixed rod 14. The staff can rotate the fixed rod 14 to drive the adjustable grinding roller 13 to deflect, so that the angle of the outer wall of the adjustable grinding roller 13 is consistent with the beveled chamfered surface of the edge of the box body 4. The elastic force of the spring 19 presses the latch 18 against the limit seat 15 to fix the angle of the adjustable grinding roller 13.

[0037] As another embodiment further provided by the present invention, the limiting seat 15 is provided with a retention groove 17 and an arc groove 16 that are interconnected, and the depth of the retention groove 17 is greater than that of the arc groove 16 .

[0038] Specifically, the latch 18 slides along the arc groove 16. When the latch 18 is located in the retention groove 17, the angles between the adjustable grinding roller 13 and the horizontal plane are 30°, 45°, 60° and 90° respectively. At this time, due to the greater depth of the retention groove 17, the extended length of the latch 18 is greater, so the latch 18 stops in the retention groove 17, so that the current angle of the adjustable grinding roller 13 is fixed.

[0039] As another embodiment further provided by the present invention, a movable rod 142 for engaging the latch pin 18 is slidably provided on the fixed rod 14 .

[0040] Specifically, an elastic member 143 is provided on the movable rod 142, and a supporting portion 144 is provided at the end of the movable rod 142 facing the latch 18. The two movable rods 142 are pushed closer to each other by the elastic member 143, and a groove is provided on the latch 18 to engage with the supporting portion 144. When the latch 18 is located in the retention groove 17, the groove and the supporting portion 144 correspond to each other and engage with each other, thereby locking the movable rod 142.

[0041] As another embodiment further provided by the present invention, a pressing block 141 is slidably provided on the fixed rod 14 , and the pressing block 141 pushes the movable rod 142 to move in opposite directions.

[0042] Specifically, the pressure block 141 slides with the two movable rods 142. When the movable rod 142 needs to be unlocked, the pressure block 141 is pressed down, and the pressure block 141 pushes the two movable rods 142 to move away from each other, so that the elastic member 143 is compressed and stores force, and the supporting portion 144 is staggered with the groove, and the movable rod 142 is no longer locked.

[0043] Working principle: In the default state, the adjustable grinding roller 13 is located at the lowest point, and the adjustable grinding roller 13 is driven to rotate, and then the mechanical arm 2 drives the adjustable grinding roller 13 to move, and the beveled and chamfered parts of the edge of the box body 4 are ground and deburred. The staff can drive the adjustable grinding roller 13 to deflect by rotating the fixed rod 14, so that the outer wall of the adjustable grinding roller 13 and the beveled and chamfered surface angle of the edge of the box body 4 are consistent, and the elastic force of the spring 19 pushes the pin 18 against the arc groove 16. When the pin 18 is in the retention groove 17, the extended length of the pin 18 is large, so that the pin 18 stops when it is in the retention groove 17, and the groove corresponds to the support part 144 and is engaged with each other to lock the movable rod 142. When the movable rod 142 needs to be unlocked, the pressing block 141 is pressed downward, and the pressing block 141 pushes the two movable rods 142 to move away from each other, causing the elastic member 143 to compress and accumulate force, and the supporting portion 144 is offset from the groove, and the movable rod 142 is no longer locked. When the edge of the box body 4 is an arc-shaped chamfer, the rounding roller 111 is driven to approach the box body 4, driving the rounding roller 111 to rotate, and the rounding roller 111 approaches the arc-shaped chamfer and grinds it, thereby achieving targeted grinding and deburring operations on the edges of different boxes 4.

[0044] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
