[0075] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0076] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0077] like Figures 1 to 13 As shown, this solution provides an automatic assembly device for assembling a second workpiece 2 and a third workpiece 3 onto a first workpiece 1. The device includes: an operating table 4 with a support platform 5 mounted thereon; a first feeding unit 6 disposed on the side of the operating table 4 for conveying the first workpiece 1; a two-dimensional transport platform 7 disposed on the operating table 4 for transporting the first workpiece 1 on the support platform 5; a second feeding unit 8 disposed on the side of the support platform 5 for conveying the second workpiece 2 and assembling it into the first workpiece 1; a fastening unit 9 having a first fastener 10 and a second fastener 11 movably disposed above the movement path of the first workpiece 1, the first fastener 10 for riveting the first workpiece 1 and the second fastener 11 for flattening the first workpiece 1; a third feeding unit 12 disposed on the side of the fastening unit 9 for conveying the third workpiece 3 and assembling it onto the first workpiece 1; and a collecting unit 13 disposed at the end of the support platform 5 for receiving the assembled finished workpiece.

[0078] During operation, the first workpiece 1, conveyed by the first feeding unit 6, is transported to the support platform 5 by the two-dimensional conveying platform 7. Next, the two-dimensional conveying platform 7 transports the first workpiece 1 to the location of the second feeding unit 8. Then, the second feeding unit 8 assembles the second workpiece 2 it conveys into the designated position within the first workpiece 1, completing the first assembly step. Next, the two-dimensional conveying platform 7 continues to transport the first workpiece 1 to the location of the fastening unit 9. The first fastener 10 performs a riveting operation on the first workpiece 1, while the second fastener 11 flattens the first workpiece 1, thus achieving a stable connection between the first workpiece 1 and the second workpiece 2. Subsequently, the two-dimensional conveying platform 7 continues to transport the first workpiece 1 to the location of the third feeding unit 12. The third feeding unit 12 assembles the third workpiece 3 onto the first workpiece 1. At this point, the assembly process of the entire set of workpieces is completed. Finally... The two-dimensional transport platform 7 transports the assembled finished workpieces to the collection unit 13 for centralized collection. During this process, the first fastener 10 and the second fastener 11 in the fastening unit 9 sequentially perform riveting and flattening on the first workpiece 1, which not only enhances the connection strength between the first workpiece 1 and the second workpiece 2, but also improves the sealing performance and appearance flatness of the product. This is particularly suitable for precision product assembly scenarios with high requirements for connection quality. Through the above structural design, the automatic assembly device in this solution realizes fully automated operation from the transportation of the first workpiece 1, the transportation and insertion of the second workpiece 2, the riveting and flattening, the transportation and assembly of the third workpiece 3, to the collection of finished workpieces. This effectively reduces the reliance on human experience, lowers labor intensity and labor costs, and improves production efficiency. It is particularly suitable for the continuous production needs of large-volume, standardized products.

[0079] Furthermore, the fastening unit 9 also includes: a first support base 14, which is disposed on the side of the support platform 5; a first drive member 15, which is disposed on the first support base 14, and a first fastener 10 is connected to the output end of the first drive member 15, the first drive member 15 being used to drive the first fastener 10 to move; a dust extraction member 16, which is connected to the first support base 14 and located on the side of the first fastener 10, for cleaning metal shavings and dust generated during the riveting process; a positioning rod 17, which is disposed on the support platform 5 and disposed opposite to the first fastener 10, the positioning rod 17 being inserted into the first workpiece 1, for positioning the first workpiece 1; and a second support base 18, which is located on the side of the first support base 14, a second drive member 19 is connected to the second support base 18, and a second fastener 11 is connected to the output end of the second drive member 19, for driving the second fastener 11 to move in the vertical direction.

[0080] The first workpiece 1 has an internal through hole. The second workpiece 2 is precisely placed into the through hole by the second feeding unit 8, and the side wall of the second workpiece 2 is engaged with the inner wall of the through hole to achieve initial positioning. When the two-dimensional conveying platform 7 transports the first workpiece 1, which has already had the second workpiece 2 placed, to the position of the fastening unit 9, the positioning rod 17 is inserted into the first workpiece 1 from the bottom of the through hole to achieve precise positioning of the first workpiece 1. Subsequently, the first driving member 15 drives the first fastener 10 to move downward in the vertical direction, aligning it with the predetermined processing position on the side wall of the through hole of the first workpiece 1. When the first fastener 10 descends to the predetermined height, the first driving member 15 switches to rotation mode and drives the first fastener 10 to rotate at high speed while maintaining a certain axial pressure, performing riveting processing on the predetermined processing position on the side wall of the through hole. At the same time, the positioning rod 17 is inserted into the first workpiece 1 from the bottom of the through hole to achieve precise positioning of the first workpiece 1. Simultaneously, the dust-collecting component 16 on the side of the first fastener 10 is activated to absorb and clean the metal shavings and dust generated during the riveting process, preventing dust accumulation from affecting subsequent assembly accuracy or equipment operation stability. After riveting is completed, the first driving component 15 drives the first fastener 10 to rise vertically and return to the initial position. Subsequently, the two-dimensional conveying platform 7 transports the riveted first workpiece 1 to directly below the second fastener 11. The second driving component 19 is activated, driving the second fastener 11 to move vertically downward to flatten the riveted part, thereby enhancing the connection strength between the first workpiece 1 and the second workpiece 2 and improving the flatness of the product appearance. The first fastener 10 is preferably a riveting head, the first driving component 15 is preferably a motor, and the second driving component 19 can be a motor or a cylinder.

[0081] Furthermore, the first feeding unit 6 includes: a first vibratory feeder 20, the discharge end of which is provided with a first feeding track 21; the discharge end of the first feeding track 21 is movably provided with a first moving block 22, the first moving block 22 having a blocking part 23 and a receiving groove; a third driving member 24, the first moving block 22 being connected to the output end of the third driving member 24, the third driving member 24 being used to drive the first moving block 22 to move.

[0082] The first workpiece 1 enters the first feeding track 21 from the discharge end of the first vibratory feeder 20. When a first workpiece 1 is conveyed to the receiving trough along the first feeding track 21, the third driving component 24 is activated, driving the first moving block 22 to move, thereby transporting the first workpiece 1 in the receiving trough to the designated conveying position. The two-dimensional conveying platform 7 then grabs the first workpiece 1 and transports it to the support platform 5. While the first moving block 22 drives the first workpiece 1 to move to the conveying position, the baffle part 23 on the first moving block 22 moves synchronously to the discharge end of the first feeding track 21 to block the continued fall of subsequent first workpieces 1, thereby realizing the sequential conveying of a single first workpiece 1 and preventing jamming or misalignment caused by multiple first workpieces 1 entering at the same time, thus improving the stability and reliability of the feeding. The third driving component 24 can be a motor, hydraulic cylinder, or pneumatic cylinder.

[0083] The first feeding track 21 is preferably a linear vibrating feeder, which is an automated device that uses vibration to continuously and directionally convey materials or workpieces along a straight path. It is widely used in various industrial fields, especially in automated production lines requiring the sorting, orientation, and efficient feeding of small parts. The linear vibrating feeder propels materials along a specific direction by generating periodic vibrations. Its core principle lies in utilizing the difference between inertial force and friction, allowing the material to gradually slide forward on a slightly inclined conveying surface.

[0084] Furthermore, the two-dimensional transport platform 7 includes: a first movable seat 25, which is movably disposed on the side of the support platform 5, and push blocks 26 are provided on both sides of the first movable seat 25. The push blocks 26 have locking grooves 27, and the first workpiece 1 is movably locked in the locking grooves 27. The first movable seat 25 is used to drive the push blocks 26 to move; a first pneumatic gripper 28, which is movably disposed above the first movable seat 25 and located between the push blocks 26 on both sides. Both the push blocks 26 and the first pneumatic gripper 28 are used to transport the first workpiece 1; and a fourth driving member 29, the first pneumatic gripper 28 is connected to the output end of the fourth driving member 29, and the fourth driving member 29 is used to drive the first pneumatic gripper 28 to move in the vertical direction.

[0085] Furthermore, the two-dimensional transport platform 7 also includes: a third support base 30, which is disposed on the side of the support platform 5, a first slide rail 31 is disposed on the third support base 30, and a second movable seat 32 is slidably disposed on the first slide rail 31; a fifth driving member 33, which is connected to the third support base 30, and the output end of the fifth driving member 33 is connected to the second movable seat 32, and the fifth driving member 33 is used to drive the second movable seat 32 to move closer to or further away from the support platform 5 in the horizontal direction; a second slide rail 34 is disposed on the second movable seat 32, and a third movable seat 35 is slidably disposed on the second slide rail 34, and the first movable seat 25 and the fourth driving member 29 are both connected to the third movable seat 35; a sixth driving member 36, which is disposed on the second movable seat 32, and the output end of the sixth driving member 36 is connected to the third movable seat 35, and the sixth driving member 36 is used to drive the third movable seat 35 to move horizontally in a direction parallel to the support platform 5.

[0086] During operation, the fifth drive unit 33 drives the second moving seat 32 to move horizontally toward the support platform 5, thereby moving the corresponding push block 26 to the gripping position. At this time, the first workpiece 1 in the receiving groove engages with the locking groove 27 on the push block 26. Subsequently, the sixth drive unit 36 ​​starts, driving the third moving seat 35 to move in a direction parallel to the support platform 5, causing the push block 26 and the first workpiece 1 it engages to disengage from the receiving groove, and transporting the first workpiece 1 along the support platform 5 to the location of the second loading unit 8. When the second loading unit 8 is reached, the sixth drive unit 36 ​​stops running, and the fifth drive unit 33 starts to drive in the opposite direction, driving the second moving seat 32 to move horizontally away from the support platform 5, thereby causing the first moving seat 25 and the push block 26 on it to move away from the first workpiece 1, so that the first workpiece 1 disengages from the locking groove 27.

[0087] After the second workpiece 2 is precisely placed into the through hole of the first workpiece 1 by the second feeding unit 8, the pushing block 26, driven by the two-dimensional conveying platform 7, continues to transport the first workpiece 1 to the gripping position of the first pneumatic gripper 28 on the support platform 5 and disengages from the gripping state; subsequently, the fifth driving member 33 drives the second moving seat 32 and the third moving seat 35 together to move closer to the support platform 5; the fourth driving member 29 on the third moving seat 35 and the first pneumatic gripper 28 then approach the first workpiece 1 on the support platform 5 where the second workpiece 2 has been placed; when the first pneumatic gripper 28 moves to directly above the first workpiece 1, the fourth driving member 29 is activated, driving the first pneumatic gripper 28 to descend to the preset gripping height, and the first pneumatic gripper 28 then clamps and grips the first workpiece 1; then, the fourth driving member 29 reverses the drive, causing the first pneumatic gripper 28 and the gripped first workpiece 1 to rise to the preset height; subsequently... The sixth driving component 36 drives the fourth driving component 29 and the first pneumatic gripper 28 through the third moving seat 35, moving them in a direction parallel to the support platform 5 to the position of the fastening unit 9, so that the first workpiece 1 is exactly above the positioning rod 17; then, the fourth driving component 29 continues to drive the first pneumatic gripper 28 to descend, placing the first workpiece 1 on the support platform 5, while the positioning rod 17 inserts into the first workpiece 1 along the bottom of the through hole to complete the precise positioning; after riveting is completed, the first pneumatic gripper 28, driven by the two-dimensional transport platform 7, transports the first workpiece 1 to the position directly below the second fastener 11 and releases the first workpiece 1; after the second fastener 11 completes the flattening treatment of the riveting part, the push block 26 on the other side of the first moving seat 25 continues to transport the first workpiece 1; wherein, the fourth driving component 29, the fifth driving component 33 and the sixth driving component 36 can all be motors, hydraulic cylinders or pneumatic cylinders.

[0088] Further, the second feeding unit 8 includes: a second vibratory feeder 37, whose discharge end is provided with a second feeding track 38, and a receiving block 39 located at the discharge end of the second feeding track 38 on the support platform 5, wherein the second workpiece 2 flows into the receiving block 39 along the second feeding track 38; a first detection component 40, which is located on the side of the receiving block 39, for detecting whether the second workpiece 2 is placed inside the receiving block 39; an assembly component 41, which is movably disposed above the support platform 5, for picking up the second workpiece 2 from the receiving block 39 and assembling it into the first workpiece 1; a seventh driving component 42, the output end of which is connected to a second moving block 43, the assembly component 41 being connected to the second moving block 43, and the seventh driving component 42 driving the assembly component 41 to move horizontally through the second moving block 43; and an eighth driving component 45, the output end of which is connected to a first lifting block 44, the seventh driving component 42 being connected to the first lifting block 44, and the eighth driving component 45 driving the seventh driving component 42 to move vertically through the first lifting block 44.

[0089] During operation, the second workpiece 2 enters the second feeding track 38 from the discharge end of the second vibrating plate 37 and is conveyed by the second feeding track 38 to the receiving block 39 on the support platform 5. When the first detection element 40 detects that the second workpiece 2 has been placed on the receiving block 39, the eighth drive element 45 is activated, driving the assembly 41 to descend vertically to the preset suction height via the second moving block 43. At this time, the assembly 41 is connected to the air source through the air pipe, generating a negative pressure suction force, thereby sucking up the second workpiece 2 on the receiving block 39. Subsequently, the eighth drive element 45 reverses its direction, driving the assembly 41 and the suctioned second workpiece 2 to rise together via the second moving block 43. Immediately afterwards, the seventh drive element 42 is activated, driving the assembly...
