Description

Technical Field

[0001] The utility model relates to a flange assembly, in particular to a quick-change flange assembly used for replacing tools connected to a mechanical arm. Background Art

[0002] In order to pursue higher productivity and efficiency and reduce personnel costs, most of today's automated production lines use robotic arms for operations. However, in order to make the robotic arm multi-purpose, a single robotic arm can be used to replace the tool connected to the robotic arm to perform operations such as gripping, suction, and dispensing. At this time, a connection device that can be quickly replaced is very important.

[0003] The current quick-change device has a robot arm end and a tool end, which are connected to a robot arm and a required tool respectively. A recessed hole is provided at the robot arm end, and a column is provided at the tool end. The recessed hole and the column can be engaged with each other. In order to achieve stable engagement and prevent loosening, a plurality of steel balls and grooves corresponding to the steel balls are provided on the inner wall of the recessed hole and the outer wall of the column respectively. When the robot arm and the tool are engaged and connected by the quick-change device, the steel balls are embedded in the corresponding grooves to ensure a stable engagement.

[0004] However, since the steel ball needs to be engaged in the groove, it is easy to wear, and the steel ball is embedded in the outer wall of the column, which is not easy to replace and repair. If it needs to be replaced, the column at the tool end needs to be removed to take out the steel ball, which is inconvenient.

[0005] In view of this, proposing a better improvement plan is an urgent problem to be solved in the industry. Utility Model Content

[0092] The following is a detailed description of the technical means used by the present invention to achieve the intended purpose of the present invention with reference to the drawings and preferred embodiments of the present invention.

[0093] Please refer to Figure 1 and Figure 2 The utility model provides a quick-change flange assembly, which is used to connect a robot arm and has a cover body 10, a first component 20, and a second component 30. In this embodiment, the first component 20 is connected to a tool, and the second component 30 is connected to a robot arm. The second component 30 is detachably connected to the first component 20, and the cover body 10 is attached to a side of the second component 30 away from the first component 20. In other words, the second component 30 is sandwiched between the first component 20 and the cover body 10.

[0094] Please refer to Figure 3 The cover 10 has an air inlet channel 11, one end of which is located on a side of the cover 10 that is in contact with the second component 30. In this embodiment, the other end of the air inlet channel 11 is located on the side of the cover 10. In other embodiments, the other end of the air inlet channel 11 may also be located at other positions.

[0095] Please refer to Figure 2 The first component 20 has a base 21 , a column 22 , a first power module 23 , at least one first pneumatic channel 24 , and a plurality of positioning pins 25 .

[0096] The cylinder 22 protrudes from one side of the base 21 toward the second component 30 and has at least one groove 221. The groove 221 is disposed on the outer annular surface of the cylinder 22. In the present embodiment, the groove 221 is an annular groove. In other embodiments, the number and shape of the grooves 221 are not limited thereto. In the present embodiment, the first charged module 23 is connected to one side of the base 21 and has a first probe. The first probe is disposed on a side of the first charged module 23 close to the second component 30. At least one first pneumatic channel 24 connects the side of the base 21 and a side of the base 21 close to the second component 30. A plurality of positioning pins 25 protrude from the base 21 toward the second component 30 and are located on the same surface of the base 21 as the cylinder 22.

[0097] Combination Figure 4 and Figure 5 The second component 30 has a concave hole 31 , at least one fastening component 32 , a concave annular groove 33 , a supporting member 34 , a second live module 35 , at least one second pneumatic channel 36 , a plurality of positioning holes 37 , and a sensing member 38 .

[0098] The recessed hole 31 is disposed on one side of the second component 30, and the column 22 can be inserted into the recessed hole 31. The fastening component 32 is located between the recessed hole 31 and the side of the second component 30. In this embodiment, the second component 30 has four fastening components 32, and each fastening component 32 is spaced apart from each other. In other embodiments, the number of fastening components 32 is not limited thereto.

[0099] Each fastening assembly 32 has a moving channel 321, a moving member 322, and a closing member 323. The moving channel 321 can penetrate the side wall of the recessed hole 31 and communicate with the side of the second assembly 30. The moving member 322 is movably disposed in the moving channel 321 and has a block 3221 and an elastic member 3222.

[0100] The block 3221 is located in the moving channel 321 and can selectively protrude into the concave hole 31. When the column 22 of the first component 20 is inserted into the concave hole 31 of the second component 30, the block 3221 can abut against one of the grooves 221. In this embodiment, the blocks 3221 are arranged in groups of two, and each group of blocks 3221 is respectively arranged on both sides of the column 22, so that the blocks 3221 can clamp the column 22 therein. In other embodiments, the number and position of the blocks 3221 are not limited thereto, as long as the column 22 can be fixed in the concave hole 31. The block 3221 has a first section 3223, a second section 3224, and an inclined surface 3225. The first section 3223 is located at one end of the block 3221 close to the concave hole 31. The second section 3224 is located at one end of the block 3221 away from the concave hole 31, and the diameter of the second section 3224 is larger than the first section 3223. The inclined surface 3225 is disposed between the first section 3223 and the second section 3224 .

[0101] The elastic member 3222 is located in the moving channel 321 and is connected to one end of the block 3221 close to the side of the second component 30, and tends to push the block 3221 into the recessed hole 31. The closing member 323 is detachably disposed on the side of the second component 30 and can close the moving channel 321. When the closing member 323 is opened, the moving channel 321 can communicate with the outside, thereby, the moving member 322 can be taken out of the moving channel 321 for replacement.

[0102] The concave annular groove 33 is arranged on the other side of the second component 30 relative to the concave hole 31, and is connected to the air inlet channel 11 and the moving channel 321 of each clamping component 32. The abutting member 34 is arranged in the concave annular groove 33, and when the air inlet channel 11 is inhaled from the side of the cover body 10, the abutting member 34 can move in the direction of the moving channel 321. The abutting member 34 has a plate 341, which is arranged on a side of the abutting member 34 close to the moving member 322, and when the air inlet channel 11 is inhaled, the plate 341 will abut against one end of the moving member 322 close to the concave hole 31, so that the moving member 322 cannot move toward the concave hole 31. In the present embodiment, the plate 341 abuts against the inclined surface 3225 of the block 3221, and when the plate 341 moves toward the block 3221, the plate 341 further pushes the block 3221 along the inclined surface 3225 in the direction away from the concave hole 31.

[0103] The second charged module 35 is connected to the side of the second component 30, and when the first component 20 is connected to the second component 30, the first charged module 23 can be electrically connected to the second charged module 35. In this embodiment, the second charged module 35 has a second probe, which is arranged on a side of the second charged module 35 close to the first component 20; when the first component 20 is connected to the second component 30, the first probe can be electrically connected to the second probe. In this embodiment, the first charged module 23 and the second charged module 35 are electrically connected by using the first probe and the second probe. In other embodiments, the form of electrical connection between the first charged module 23 and the second charged module 35 is not limited to this.

[0104] Please refer to Figure 6 At least one second pneumatic channel 36 is connected to the side of the second component 30 and the side of the second component 30 close to the first component 20. When the first component 20 is connected to the second component 30, each second pneumatic channel 36 can be connected to one of the first pneumatic channels 24. In this embodiment, there are eight first pneumatic channels 24 and eight second pneumatic channels 36, which correspond to each other one by one, and eight independent air source channels are formed, so that the tool on the first component 20 can be connected to one of the first pneumatic channels 24 and one of the second pneumatic channels 36 as needed, and thereby control the tool on the first component 20. In other embodiments, the number of the first pneumatic channels 24 and the second pneumatic channels 36 is not limited thereto.

[0105] Please refer to Figure 7 The number and position of the positioning holes 37 correspond to the positioning pins 25 on the first component 20. When the first component 20 and the second component 30 are connected, each positioning pin 25 can be inserted into one of the positioning holes 37. Thus, when the first component 20 and the second component 30 are engaged, they can be positioned by the positioning holes 37 and the positioning pins 25. Preferably, the first component 20 has two positioning pins 25, and the second component 30 has two positioning holes 37.

[0106] The two ends of the sensing element 38 are respectively connected to one of the positioning holes 37 and the side of the second component 30, and can sense whether the positioning pin 25 corresponding to the positioning hole 37 is located in the positioning hole 37. In this embodiment, the sensing element 38 uses optical sensing to confirm the difference in light in the positioning hole 37 to identify whether the first component 20 and the second component 30 are interlocked.

[0107] Please refer to Figure 8 and Fig. 9 When the first component 20 connected to the tool is to be mated with the second component 30 connected to the robot arm, air will first be taken in from the air inlet channel 11 of the cover body 10 to push the abutment member 34 of the second component 30 in the direction of the moving channel 321, so that the plate body 341 of the abutment member 34 abuts against the block body 3221, and the plate body 341 pushes the block body 3221 in a direction away from the recessed hole 31 along the inclined surface 3225 of the block body 3221, so that the column 22 of the first component 20 can be inserted into the recessed hole 31 of the second component 30. When the first component 20 is combined with the second component 30, the air intake channel 11 is closed so that air is no longer taken in. At this time, the abutment member 34 of the second component 30 is no longer abutted against the block 3221 because it is not pushed by the gas. The block 3221 is pushed by the elastic member 3222 to move toward the recessed hole 31, and finally protrudes from the recessed hole 31 and engages in the groove 221 of the column 22, clamping the column 22 of the first component 20.

[0108] The advantage of the present invention is that the steel ball embedded in the column 22 is replaced by a block 3221 located in the second component 30. The block 3221 is limited by the plate 341 of the abutment member 34. When the first component 20 is to be combined with the second component 30, the block 3221 will not protrude from the recessed hole 31. Therefore, when the column 22 is inserted into the recessed hole 31, the block 3221 will not rub against the outer wall surface of the column 22 to cause wear. In addition, each block 3221 and each elastic member 3222 are closed in a moving channel 321 by a detachable sealing member 323. When the block 3221 or the elastic member 3222 needs to be replaced, the corresponding sealing member 323 can be removed and the moving channel 321 can be opened to replace the individual block 3221 or the elastic member 3222 without replacing the second component 30, thereby reducing the cost and time of repair.

[0109] The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
