Description

Technical Field

[0001] This utility model belongs to the field of robot protective cover technology, and in particular relates to a lightweight safety protective cover for collaborative robots. Background Technology

[0002] Collaborative robots used in workshops are intelligent robotic arms that can share workspaces with humans and work together safely. Robot protective covers play a protective role during the processing of robotic arms. For example, during the grinding process of a grinding robot, debris will fly everywhere, and during the welding process of a welding robot, sparks will fly everywhere. In this case, protective covers are needed to prevent debris or metal from flying everywhere during the processing and causing environmental pollution. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a lightweight safety shield for collaborative robots.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A lightweight safety shield for a collaborative robot includes a robotic arm, wherein a clamp is detachably provided on the side of the robotic arm, and connecting plates are symmetrically provided on the outer side of the clamp;

[0006] The mounting plate has a first groove in the middle, which is circular. The mounting plate is sleeved around the robotic arm and is detachably connected to the connecting plate.

[0007] The mounting plate is rectangular, and the mounting plate is surrounded by a first cover plate, with four first cover plates forming a rectangular cover.

[0008] A second cover plate is rotatably provided on the side of the first cover plate, and a connecting rod is rotatably provided on the outer side of the second cover plate;

[0009] An adjusting block is fixedly provided on the outer side of the first cover plate. The adjusting block has multiple adjusting slots, and one end of the connecting rod is snapped into the adjusting slot.

[0010] A third cover plate is connected between two adjacent second cover plates, and the third cover plate has a foldable structure.

[0011] The above technical solution involves attaching and fixing the clamp to the outside of the robotic arm, allowing the robotic arm to pass through the first groove of the mounting plate. After connecting the connecting plate to the mounting plate, the connecting rod is engaged in different adjustment slots to adjust the rotation angle of the second cover plate relative to the first cover plate, thereby adjusting the enclosed area of ​​the second cover plate to accommodate workpieces of different sizes. When the second cover plate rotates, the third cover plate will fold or extend to correspond to the distance between the two second cover plates, avoiding interference with the rotation of the second cover plate, preventing debris from flying during processing, and protecting the processing environment.

[0012] Furthermore, the clamp includes two semicircular rings, one end of which is rotatably connected by a pin, and the other end is connected by a bolt.

[0013] The above technical solution allows for easy and quick installation of the clamp by rotating the semi-circular ring to open it, directly placing the clamp on the desired position on the robotic arm, and then securing the open end of the clamp with bolts.

[0014] Furthermore, the mounting plate has a fixing block on its side, and the fixing block has a fixing groove, which is engaged with one end of the connecting plate.

[0015] Both the fixing groove and the connecting plate are provided with screw holes, and the fixing groove and the connecting plate are connected by bolts and screw holes.

[0016] The connecting plate and the mounting plate are fixed by the above technical solution.

[0017] Furthermore, the fixing groove and the bolt side of the connecting plate are provided with spring pieces, which are located on the side of the fixing block.

[0018] The above technical solution can prevent the bolt from rotating by the elastic force of the spring, thus improving the fixing effect.

[0019] Furthermore, the connecting rod has second grooves on both sides of the end away from the second cover plate, and a plug is slidably provided in the second groove. The plug has a T-shaped cross-section and one end extends out of the second groove. The side of the plug near the adjustment groove is inclined. A first spring is provided in the second groove. One end of the first spring is connected to the side of the second groove, and the other end is connected to the plug.

[0020] The adjustment groove has a third groove on both sides, and the plug is inserted into the third groove.

[0021] With the above technical solution, one end of the connecting rod is inserted into the corresponding adjustment groove, and the insert is pressed into the second groove under pressure. After one end of the connecting rod is fully inserted into the adjustment groove, the insert slides from the second groove into the third groove under the spring force, thus completing the fixation of the connecting rod.

[0022] Furthermore, the third groove extends through the side of the adjusting block, and the third groove is T-shaped;

[0023] A push rod is slidably disposed within the third groove. The push rod is I-shaped, and one end of the push rod extends out of the third groove and is located outside the adjusting block.

[0024] With the above technical solution, the insert can be pushed out of the third groove by pushing the push rods on both sides.

[0025] Furthermore, a second spring is sleeved in the middle of the side of the push rod, and the two ends of the second spring are respectively connected to the outer side of the adjusting block and the end of the push rod.

[0026] With the above technical solution, after the push rod is pushed into the third groove and the insert block is removed, it can return to its original position under the elastic force of the second spring, without the need for manual reset.

[0027] Furthermore, the second cover plate has an observation window on its side, through which the internal processing can be observed.

[0028] This utility model has the following beneficial effects:

[0029] The clamp is placed on the outside of the robotic arm and fixed in place. The robotic arm passes through the first groove of the mounting plate. After connecting the connecting plate to the mounting plate, it is engaged in different adjustment slots through the connecting rod. The rotation angle of the second cover plate relative to the first cover plate is adjusted, thereby adjusting the enclosed area of ​​the second cover plate to adapt to workpieces of different sizes. When the second cover plate rotates, the third cover plate will fold or extend to correspond to the distance between the two second cover plates, avoiding interference with the rotation of the second cover plate, preventing debris from flying during processing, and protecting the processing environment.

The mounting plate 3 is fitted around the robotic arm 1 and detachably connected to the connecting plate 21. A fixing block 32 is provided on the side of the mounting plate 3. A fixing groove 33 is formed on the fixing block 32, and the fixing groove 33 is correspondingly engaged with one end of the connecting plate 21. Screw holes are formed on both the fixing groove 33 and the connecting plate 21 for fixing... The groove 33 and the connecting plate 21 are connected by bolts and threaded holes. The bolt side of the fixing groove 33 and the connecting plate 21 is provided with a spring piece 34. The spring piece 34 is located on the side of the fixing block 32. The mounting plate 3 is rectangular and the mounting plate 3 is provided with a first cover plate 4 around its perimeter. The four first cover plates 4 form a rectangular cover. The side of the first cover plate 4 is rotatably provided with a second cover plate 5. The outer side of the second cover plate 5 is rotatably provided with a connecting rod 51. The outer side of the first cover plate 4 is fixedly provided with an adjusting block 41. The adjusting block 41 is provided with multiple adjusting grooves 42. One end of the connecting rod 51 is snapped into the adjusting groove 42. A third cover plate 6 is connected between two adjacent second cover plates 5. The third cover plate 6 is a foldable structure. The side of the second cover plate 5 is provided with an observation window 7, which can be used to observe the internal processing.

[0048] The clamp 2 is placed on the outside of the robotic arm 1 and fixed in place. The robotic arm 1 passes through the first groove 31 of the mounting plate 3. After connecting the connecting plate 21 to the mounting plate 3, it is engaged in different adjustment slots 42 by the connecting rod 51. The rotation angle of the second cover plate 5 relative to the first cover plate 4 is adjusted, thereby adjusting the enclosed area of ​​the second cover plate 5 to adapt to workpieces of different sizes. When the second cover plate 5 rotates, the third cover plate 6 will fold or extend to correspond to the distance between the two second cover plates 5, so as to avoid interference with the rotation of the second cover plate 5.

[0049] Preferably, the connecting rod 51 has two second grooves 52 on both sides of the end away from the second cover plate 5. A plug 53 is slidably provided in the second groove 52. The plug 53 has a T-shaped cross section and one end extends out of the second groove 52. The side of the plug 53 near the adjustment groove 42 is inclined. A first spring 54 is provided in the second groove 52. One end of the first spring 54 is connected to the side of the second groove 52, and the other end is connected to the plug 53. A third groove 43 is provided on both sides of the adjustment groove 42. The plug 53 is inserted into the third groove 43. The third groove 43 penetrates the side of the adjustment block 41 and is T-shaped. A push rod 44 is slidably provided in the third groove 43. The push rod 44 is I-shaped, and one end of the push rod 44 extends out of the third groove 43 and is located outside the adjustment block 41. A second spring 45 is sleeved in the middle of the side of the push rod 44. The two ends of the second spring 45 are connected to the outside of the adjustment block 41 and the end of the push rod 44, respectively.

[0050] Insert one end of the connecting rod 51 into the corresponding adjustment groove 42. The insert block 53 is pressed into the second groove 52 under pressure. After one end of the connecting rod 51 is fully inserted into the adjustment groove 42, the insert block 53 slides out of the second groove 52 and into the third groove 43 under the elastic force of the spring, thus fixing the connecting rod 51. By pushing the push rods 44 on both sides, the insert block 53 can be pushed out of the third groove 43. Under the elastic force of the second spring 45, it can return to its original position without manual reset.

[0051] The working principle of this utility model is as follows: Before the robotic arm 1 processes the workpiece, the clamp 2 is placed on the outside of the robotic arm 1 and fixed with bolts. The robotic arm 1 passes through the first groove 31 of the mounting plate 3. The diameter of the first groove 31 is larger than the width of the robotic arm 1 and also larger than the outer diameter of the clamp 2, allowing the robotic arm 1 to pass through easily. The connecting plate 21 engages with the fixing groove 33 on the mounting plate 3 and is fixed with bolts. After installation, the angles of the four second cover plates 5 can be adjusted according to the size of the workpiece, and one end of the connecting rod 51 is inserted into the corresponding groove. In the adjustment groove 42, the insert 53 is pressed into the second groove 52 under pressure. After one end of the connecting rod 51 is fully inserted into the adjustment groove 42, the insert 53 slides out of the second groove 52 and into the third groove 43 under the elastic force of the spring, thus fixing the connecting rod 51. When the angle needs to be adjusted, it is only necessary to push the push rods 44 on both sides to push the insert 53 out of the third groove 43 and re-insert it into the corresponding adjustment groove 42. The push rods 44 can return to their original position under the elastic force of the second spring 45 without manual reset.

[0052] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
