[0002] like Figure 1 The workpiece structure shown includes a mandrel 60, a nut 61, a cap 62, a sealing ring, and a sleeve 63. The assembly process begins with the correct installation of the sealing ring, followed by inserting the mandrel 60 into the nut 61. Next, the cap 62 is placed over the nut 61. The final step involves using a crimping machine 51 to secure the sleeve 63 to the mandrel 60, completing the assembly.

[0067] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0068] An automatic assembly device comprises: a workbench 1, a rotating disk 2, a nut feeding unit 3, a core shaft feeding unit 4, a sealing ring feeding unit 5, a cap feeding unit 6 and a sleeve assembly unit 7.

[0069] Among them, the rotating disk 2 is rotatably set on the workbench 1 and has several installation stations 8; the nut loading unit 3, the core shaft loading unit 4 and the cap loading unit 6 are arranged in sequence around the circumference of the rotating disk 2, the nut loading unit 3 is used to provide the nut 61 to be assembled for the installation station 8, the core shaft loading unit 4 is used to provide the core shaft 60 to be assembled for the installation station 8 and insert the core shaft 60 into the nut 61, and the cap loading unit 6 is used to assemble the cap 62 on the core shaft 60 with the assembled nut 61; the nut loading unit 3 and the cap loading unit 6 both have a first detection part 9 set on the workbench 1, and a second detection part 9 is set on the workbench 1. An inspection member 9 is used to inspect the nut 61 and the cap 62 to be assembled. The core shaft loading unit 4 has a second inspection member 10 arranged on the workbench 1, and the second inspection member 10 is used to inspect the core shaft 60; the sealing ring loading unit 5 is arranged between the core shaft loading unit 4 and the nut loading unit 3, and is used to install the sealing ring on the core shaft 60 that has passed the inspection on the second inspection member 10; the sleeve assembly unit 7 is arranged on the workbench 1 and is on the side of the rotating disk 2 away from the core shaft loading unit 4. The sleeve assembly unit 7 is used to assemble the sleeve 63 for the core shaft 60 with the nut 61, the sealing ring and the cap 62 installed.

[0070] Based on the above embodiment, an exemplary structure of this solution is as follows Figures 2 to 9 As shown, four installation stations 8 are provided on the rotating disk 2, three of which correspond to the nut loading unit 3, the core shaft loading unit 4 and the cap loading unit 6 respectively. The fourth installation station 8 is used to transport the core shaft 60 with the sealing ring and the cap 62 installed to one of the sleeve assembly units 7. Of course, the number of installation stations 8 can also be five, six, seven, etc.

[0071] During operation, the nut loading unit 3 and the first detection part 9 on the cap loading unit 6, as well as the second detection part 10 in the core shaft loading unit 4, first inspect the nut 61, cap 62 and core shaft 60 to be assembled, in order to ensure the assembly quality of the workpiece. After the inspection is correct, the nut loading unit 3 sends the qualified nut 61 to the installation station 8. Then, with the help of the rotating disk 2, the nut 61 is transferred to the core shaft loading unit 4. Prior to this, the sealing ring loading unit 5 has pre-installed the sealing ring on the core shaft 60 that has passed the inspection. Then the core shaft loading unit 4 moves the core shaft 60 equipped with the sealing ring to the installation station 8 and accurately embeds the core shaft 60 into the nut 61 (a step hole is provided inside the nut 61, and a limiting part is provided on the upper part of the core shaft 60. When the core shaft 60 is inserted into the nut 61, the limiting part on the core shaft 60 abuts against the small end of the step hole of the nut 61). The rotating disk 2 continues to rotate, transferring the mandrel 60, which has been assembled with the nut 61 and sealing ring, to the cap loading unit 6. This unit then secures the inspected cap 62 onto the exterior of the nut 61, completing the assembly of the cap 62. The rotating disk 2 then continues to rotate, transferring the mandrel 60, which now includes the assembled nut 61, sealing ring, and cap 62, to the sleeve assembly unit 7. This unit is responsible for installing the sleeve 63 onto the mandrel 60, thus completing the entire assembly process.

[0072] This solution relies on the synergistic effect of the workbench 1 and the rotating disk 2, as well as the automated linkage of the nut 61, the core shaft 60, the sealing ring, the cap loading unit 6 and the sleeve assembly unit 7, which not only significantly improves the assembly efficiency and finished product quality of the workpiece, but also fully meets the needs of large-scale production assembly.

[0073] Based on the above structure, this solution has made further improvements and refinements to it.

[0074] The first detection member 9 includes: a first support frame 11, which is arranged on the workbench 1, and a visual sensor 12 is arranged on the first support frame 11; a first support platform 13, which is arranged on the workbench 1 and is located on the side of the first support frame 11, and the visual sensor 12 is arranged just above the first support platform 13; a storage box 14, which is arranged on the workbench 1 and is located on the side of the first support platform 13; a first driving member 15, which is arranged on the first support platform 13, and a driving rod 16 is provided at the output end of the first driving member 15, and the first driving member 15 is used to drive the driving rod 16 to sweep across the surface of the first support platform 13; a second support frame 17, which is arranged on the first support frame 11; a second driving member 18, which is horizontally arranged on the second support frame On the support frame 17; the third driving member 19 is uprightly arranged at the output end of the second driving member 18, and the second driving member 18 is used to drive the third driving member 19 to move in the horizontal direction; the third support frame 20 is connected to the output end of the third driving member 19, and the third support frame 20 is provided with a plurality of first pneumatic clamps 21; the nut 61 and the cap 62 to be assembled can be moved to the first support platform 13 under the clamping of the first pneumatic clamp 21, and inspected by the visual sensor 12, wherein the nut 61 and the cap 62 that pass the inspection are moved to the installation station 8 under the transportation of the first pneumatic clamp 21, and the nut 61 and the cap 62 that fail the inspection are moved to the storage box 14 driven by the driving rod 16.

[0075] During operation, the second driving member 18 and the third driving member 19 drive the third support frame 20 to move in the horizontal and vertical directions, and drive the first pneumatic clamp 21 to transport the material to be assembled (nut 61 or cap) to the first support platform 13. At this time, the visual sensor 12 begins to detect the material on the first support platform 13 (detect whether there are burrs on the internal thread of the nut 61 and detect whether the opening direction of the cap 62 is facing downward). When the inspection is qualified, the second driving member 18 and the third driving member 19 again drive the third support frame 20 to move in the horizontal and vertical directions, and drive the first pneumatic clamp 21 to transport the qualified material on the first support platform 13 to the installation station 8. When the inspection result is unqualified, the first driving member 15 drives the driving rod 16 to sweep across the surface of the first support platform 13, and pushes the material on the first support platform 13 into the storage box 14, thereby completing the loading process of the nut 61 and the cap 62.

[0076] Preferably, the first driving member 15 , the second driving member 18 and the third driving member 19 are all cylinders.

[0077] like Figure 2 、 Figure 4 and Figure 5As shown, the second detection member 10 of this scheme includes: a fourth support frame 22, which is arranged on the workbench 1; a fifth support frame 23, which is arranged on the fourth support frame 22; a fourth driving member 24, which is horizontally arranged on the fifth support frame 23; a fifth driving member 25, which is vertically connected to the output end of the fourth driving member 24; a sixth support frame 26, which is connected to the output end of the fifth driving member 25, and a plurality of second pneumatic clamps 27 are provided on the sixth support frame 26; a second support platform 28, which is arranged on the workbench 1 and is located on the side of the fourth support frame 22, and a first fixing sleeve 29 is provided on the second support platform 28. The first fixing sleeve 29 is provided on the second support platform 28. The sleeve 29 is used to position the core shaft 60 to be inspected; the sixth driving member 30 is uprightly arranged on the second support platform 28, and the output end of the sixth driving member 30 is provided with a detection rod 31, and the detection rod 31 is movably inserted in the first fixed sleeve 29; the seventh driving member 32 is arranged on the second support platform 28, and the output end of the seventh driving member 32 is provided with a pressing block 33; the core shaft 60 to be inspected can be moved into the first fixed sleeve 29 under the clamping of the second pneumatic clamp 27. After the pressing block 33 is pressed on the upper end of the core shaft 60, the detection rod 31 is inserted into the core shaft 60 from bottom to top to detect the inner hole of the core shaft 60.

[0078] During operation, the fourth driving member 24 and the fifth driving member 25 drive the sixth support frame 26 to move in the horizontal and vertical directions through linkage, thereby driving the second pneumatic clamp 27 to move, so as to achieve precise positioning of the core shaft 60 to be assembled on the first fixed sleeve 29 tube. Subsequently, the seventh driving member 32 drives the pressing block 33 to be pressed down above the core shaft 60. It is worth noting that the pressing block 33 is specially designed with a through hole. After the seventh driving member 32 causes the pressing block 33 to be close to the core shaft 60, the pressing block 33, the first fixed sleeve 29 tube and the through hole of the core shaft 60 remain coaxially aligned, and the diameter of the through hole is larger than the diameter of the detection rod 31. In this design, the purpose of the second detection element is to verify whether the through hole in the center of the core shaft 60 is unobstructed.

[0079] The specific operation process is as follows: after the core shaft 60 is placed in the first fixing sleeve 29, the sixth driving member 30 drives the detection rod 31 to penetrate into the core shaft 60 from the bottom of the first fixing sleeve 29 to check the connectivity of the through hole of the core shaft 60. The preferred detection mechanism involves configuring a pressure sensor between the sixth drive member 30 and the detection rod 31 - when the through hole of the core shaft 60 is processed to standard, that is, it is completely unobstructed, the sixth drive member 30 can drive the detection rod 31 to pass through the through hole of the core shaft 60 without hindrance. At this moment, the pressure sensor will not receive the pressure feedback generated by the obstruction of the detection rod 31; on the contrary, if the through hole of the core shaft 60 is not completely opened, the detection rod 31 will encounter obstruction and act in reverse on the pressure sensor, triggering a corresponding signal indication. After the detection of the core shaft 60 is completed, the fourth drive member 24 and the fifth drive member 25 again drive the sixth support frame 26 to move in the horizontal and vertical directions through the linkage effect, and then drive the second pneumatic clamp 27 to move, and transport the qualified core shaft 60 on the first fixed sleeve 29 to the sealing ring loading unit 5 for installation of the sealing ring.

[0080] Preferably, the fourth driving member 24 , the fifth driving member 25 , the sixth driving member 30 and the seventh driving member 32 are cylinders.

[0081] like Figure 4 、 Figure 5 and Figure 6 As shown, the sealing ring loading unit 5 includes: a third support platform 34, which is arranged on the workbench 1; an eighth driving member 35, which is horizontally arranged on the third support platform 34, and the output end of the eighth driving member 35 is connected to the first movable seat 36, and the eighth driving member 35 is used to drive the first movable seat 36 to move on the third support platform 34; a second fixed sleeve 37, which is arranged on the first movable seat 36; a seventh support frame 38, which is arranged on the workbench 1 and is located on the side of the third support platform 34; an eighth support frame 39, which is connected to the seventh support frame 38; a ninth driving member 40, which is horizontally connected to the eighth support frame 39; a tenth driving member 41, which is uprightly arranged at the output end of the ninth driving member 40, and the output end of the tenth driving member 41 is provided with an assembly part 42, and the assembly part 42 is movably arranged above the second fixed sleeve 37, for installing the sealing ring on the core shaft 60 on the second fixed sleeve 37.

[0082] After the inspection of the core shaft 60 is completed, the eighth driving member 35 drives the first movable seat 36 to move in the horizontal direction, and moves the second fixed sleeve 37 to the side of the first fixed sleeve 29, and the qualified core shaft 60 is transported to the second fixed sleeve 37 by the second pneumatic clamp 27. After the core shaft 60 is placed in the second fixed sleeve 37, the eighth driving member 35 drives the first movable seat 36 to move to the bottom of the assembly part 42, and while the second fixed sleeve 37 moves to receive the core shaft 60, the ninth driving member 40 and the tenth driving member 41 are engaged. The driving part 41 drives the assembly part 42 to move in the horizontal and vertical directions, so that the assembly part 42 grabs the sealing ring to be assembled, and when the assembly part 42 is opposite to the second fixed sleeve 37, the sealing ring is installed on the core shaft 60 in the second fixed sleeve 37, thereby completing the assembly operation of the sealing ring. After the sealing ring is installed on the core shaft 60, the second pneumatic clamp 27 transports the core shaft 60 to the installation station 8 and inserts the core shaft 60 into the nut 61 to complete the assembly between the core shaft 60 and the nut 61.

[0083] Preferably, the eighth driving member 35 , the ninth driving member 40 and the tenth driving member 41 are cylinders.

[0084] Furthermore, the assembly part 42 includes: a second movable seat 43, which is connected to the output end of the tenth driving member 41; a ninth support frame 44, which is movably inserted on the second movable seat 43; an eleventh driving member 45, which is connected to the top end of the ninth support frame 44, and the output end of the eleventh driving member 45 is connected to the second movable seat 43; a three-jaw chuck 46, which is connected to the end face of the second movable seat 43, and three tightening blocks 47 are movably provided on the three-jaw chuck 46, which are used to grab the sealing ring to be assembled when the three tightening blocks 47 are away from each other, and when the sealing ring is fixed on the three tightening blocks 47, the gap between the three tightening blocks 47 is used to accommodate the end of the core shaft 60; a pushing block 48, which is connected to the ninth support frame 44, and a through hole is provided on the pushing block 48, and the three tightening blocks 47 are all inserted in the through hole. The diameter of the through hole is smaller than the outer diameter of the sealing ring fixed on the outside of the three tightening blocks 47, and is used to push the sealing ring to the outside of the core shaft 60 placed on the second fixed sleeve 37.

[0085] In the initial state, the three holding blocks 47 are brought together toward the middle. After the three holding blocks 47 are brought together, the outer shape of the lower end thereof forms a cylindrical sleeve structure. The outer diameter of the cylindrical sleeve structure is smaller than the inner diameter of the sealing ring, and the inner diameter of the sleeve is larger than the outer diameter of the portion of the core shaft 60 where the sealing ring needs to be installed.
