Description

Technical Field

[0001] This application relates to the field of workpiece assembly technology, and in particular to a workpiece insertion device. Background Technology

[0002] In the automotive manufacturing and assembly industry, small parts are needed as connectors to connect internal pipes in automobiles.

[0003] A workpiece includes a connecting ring and a connecting post. The connecting ring has a circular opening. A hole needs to be punched on the side of the connecting ring away from the circular opening, and then the connecting post is inserted into the punched position on the connecting ring.

[0004] Workers need to punch holes in the connecting ring first, and then manually align and press the connecting post with the punched holes in the connecting ring. This manual operation is easily affected by factors such as worker fatigue, differences in skill level, and insufficient or changed tool precision, which may lead to quality problems such as incomplete assembly, incorrect assembly, or omissions.

[0005] Meanwhile, due to the lack of a real-time detection mechanism, workers cannot quickly determine the quality of the assembled workpiece. A separate inspection process is typically required to check whether the connecting post is tightly inserted into the connecting ring, i.e., whether the overall length of the workpiece exceeds a set value. This not only increases time costs but also makes quality traceability difficult. Furthermore, because the connecting ring itself has a circular opening on its side, and the punching hole is located on the opposite side of this opening, and the punching position is on the same axis as the circular opening, this further increases the difficulty for workers during punching, ultimately leading to a higher defect rate and impacting production efficiency. Moreover, currently, after punching, deburring is required at the punched area to ensure a smooth finish and prevent errors during assembly with the connecting post.

[0006] Therefore, the applicant designed a workpiece insertion device that can automatically feed materials, quickly and accurately position the connecting ring, punch the side away from the circular opening, quickly trim and deburr after punching, press-fit the connecting ring and the connecting column to complete the assembly of the entire workpiece, and inspect the assembled workpiece before unloading.

[0048] Reference Figure 7As shown, the positioning component 522 has a first positioning housing 5221 installed within the first positioning seat 521. A first slide rail 5222 is arranged within the first positioning housing 5221. A first wedge block 5223 is slidably arranged on the first slide rail 5222. Two first wedge blocks 5223 are symmetrically arranged, and each first wedge block 5223 has a second guide plate 52231 and slides on the first slide rail 5222. The first wedge block 5223 can slide out of the first positioning housing 5221 to abut against the inner ring surface of the connecting ring 101. The abutment surface of the first wedge block 5223 against the inner ring surface of the connecting ring 101 is an arc-shaped surface, which better conforms to the connecting ring 101. Simultaneously, the width of the first wedge block 5223 is greater than the diameter of the circular opening 1011, therefore, the first wedge block 5223 is not affected by the circular opening 1011 when abutting against the inner ring surface of the connecting ring 101. A first motor 5225 is also arranged inside the first positioning housing 5221.

[0050] The positioning drive assembly 54 has a first rotary motor 541 fixedly arranged on the positioning base 51. A first rotating wheel 542 is arranged on the output end of the first rotary motor 541. A first synchronous belt 543 is arranged on the first rotating wheel 542 and meshes with the first positioning seat 521. The first rotary motor 541 drives the first rotating wheel 542 to rotate and drives the first positioning seat 521 to rotate through the first synchronous belt 543, so that the connecting ring 101 can be rotated and adjusted in position during the positioning process, thereby completing the positioning more accurately. The positioning platform 52, the positioning assembly 53, and the positioning drive assembly 54 cooperate with each other. The positioning platform 52 first initially places the connecting ring 101. The positioning drive assembly 54 drives the positioning platform 52 to rotate. The positioning assembly 53 provides external auxiliary positioning, and the positioning component 522 provides internal precise positioning, ensuring that the connecting ring 101 is in the accurate position. This allows for quick positioning via the original circular opening 1011 on the connecting ring 101, facilitating the punching of the positioned connecting ring 101 on the punching device 6 during subsequent transfer. This enables precise punching of the connecting ring 101, and the punching position can be aligned with the circular opening 1011 of the connecting ring 101, ensuring accurate punching position and improving production efficiency.

The discharge bracket 91 is arranged on the base 1, and the rotary cylinder 92 is arranged on the discharge bracket 91. The first rotating plate 93 is arranged on the output end of the rotary cylinder 92, and the first rotating plate 93 has a second positioning post 94 for positioning the connecting ring 101. A discharge plate 95 for discharging material is arranged on the lower side of the first rotating plate 93. The detection bracket 96 is arranged on the base 1, and the first column head 97 is provided on the detection bracket 96. The third drive cylinder 98 for moving the first column head 97 is arranged on the detection bracket 96. The first column head 97 is coaxially arranged with the first rotating plate 93. The rotary cylinder 92 can be a swing cylinder, which can realize the rotation of the first rotating plate 93. The third drive cylinder 98 drives the first column head 97 to move, inspecting the assembled workpiece 10. Simultaneously, a pressure detector is installed on the first column head 97. When the first column head 97 moves to the end of the connecting column 102 of the workpiece 10, it abuts against the end of the connecting column 102. At the same time, the pressure detector on the first column head 97 detects the pressure value of the first column head 97 on the connecting column 102. If the connecting ring 101 and the connecting column 102 are not successfully pressed together, the pressure value detected by the pressure detector will deviate from the set pressure value range, and the pressure value signal will be sent to the control center. The control center then provides feedback and determines that the pressed workpiece 10 is a defective product. It controls the cylinder to rotate towards one side of the assembly device 8, rotating the workpiece 10 on the first rotating plate 93 and dropping it into the waste box installed on the base 1. If the workpiece 10 is qualified, the rotating cylinder 92 drives the first rotating plate 93 to rotate towards the discharge plate 95, sending the workpiece 10 to the discharge plate 95 for discharge.

[0056] The implementation principle of a workpiece insertion device according to an embodiment of this application is as follows: Connecting rings 101 and connecting posts 102 are placed in the first vibrating plate 22 and the second vibrating plate 32, respectively. The first vibrating plate 22 arranges the connecting rings 101 neatly for output. The first transport plate 425 descends, causing the first gripper mechanism 43 to contact and clamp the connecting rings 101 on the first loading limit rod 2331. The conveying device 4 moves to transfer the connecting rings 101 to the next operating station, namely the positioning device 5. The conveying device 4 places the clamped connecting rings 101 on the positioning platform 52 of the positioning device 5. The first motor 5225 drives the second wedge block 5224 to rise within the first positioning housing 5221. The rising of the second wedge block 5224 drives the first positioning housing 5221 to rise. The first wedge block 5223 inside the housing 5221 is movable. The first wedge blocks 5223 arranged on both sides of the second wedge block 5224 are far apart from each other and extend out of the first positioning housing 5221. The end of the first wedge block 5223 extending out of the first positioning housing 5221 abuts against the inner side of the connecting ring 101. At the same time, in order to improve the abutment effect between the first wedge block 5223 and the connecting ring 101, the end of the first wedge block 5223 is also set as an arc surface that fits against the side surface of the connecting ring 101. After the first wedge blocks 5223 on both sides are unfolded, the connecting ring 101 placed on the first positioning seat 521 can be centered, that is, to ensure that the center of the connecting ring 101 is aligned with the center point of the first positioning housing 5221, and to ensure that the connecting ring 101 is accurately placed in the first positioning seat 521. Furthermore, the first wedge blocks 5223 on both sides achieve abutment and locking of the connecting ring 101, preventing the connecting ring 101 from shifting during the subsequent rotation of the first positioning seat 521.

[0057] The first telescopic motor drives the first guide block 532 to slide on the second slide rail 531. Simultaneously, the first guide block 532 approaches and abuts against the outer side of the connecting ring 101. Because the connecting ring 101 has a first wedge block 5223 inside, it ensures that the connecting ring 101 will not shift when it abuts against the guide post 533 on the first guide block 532. Thus, when the guide post 533 abuts against the connecting ring 101, it is compressed back into the first guide block 532. At this time, the first guide block 532 also moves to the set position, and the guide post 533 abuts against and compresses the connecting ring 101. The first rotary motor 541 starts, driving the first rotating wheel 542 to rotate. The rotation of the first rotating wheel 542 drives the first positioning seat 521 to rotate via the first synchronous belt 543. Because the positioning component 522 is arranged inside the first positioning seat 521, the positioning component 522 will rotate synchronously with the first positioning housing 5221, and during the rotation, it still ensures the locking of the connecting ring 101. As the connecting ring 101 rotates, the circular opening 1011 on the outer side of the connecting ring 101 rotates to the vicinity of the guide post 533. At this time, the guide post 533 faces the circular opening 1011 without a contact surface. The second spring 534 of the guide post 533 resets, causing the guide post 533 to move and extend, thereby achieving the engagement of the guide post 533 with the circular opening 1011 of the connecting ring 101. When the guide post 533 is engaged, the torsional force of the connecting ring 101 increases. A torsional force detector is installed on the first positioning seat 521. When the torsional force increases rapidly, a signal is sent to the control center. The control center immediately responds and stops the first rotating motor 541, thereby controlling the first positioning seat 521 to stop rotating, which means that the positioning of the connecting ring 101 is completed at this time. Because the orientation of the circular opening 1011 is uncertain when the connecting ring 101 is placed, the overall torsional force is increased when the guide post 533 engages with the circular opening 1011, causing the torsional force to exceed the set value. This indicates that the guide post 533 and the circular opening 1011 are engaged, signifying that the positioning is complete. The first telescopic motor controls the first guide block 532 to retract, disengaging the guide post 533 from the circular opening 1011. Simultaneously, the first motor 5225 descends, causing the second wedge block 5224 to descend, allowing the first wedge block 5223 to enter the first positioning housing 5221, no longer abutting against the connecting ring 101. The conveying device 4 moves to clamp the positioned connecting ring 101 and transfer it to the punching device 6. Then, the conveying device 4 retracts to prepare for the next transfer.

[0058] The first limiting component 63 on the punching device 6 limits the connecting ring 101 placed on the first placement seat 62, and the punching machine 64 punches holes in the side wall of the connecting ring 101. After punching, the connecting ring 101 is transferred to the grinding device 7 through the conveying device 4 and the second limiting component 72 limits the connecting ring 101 before grinding the punched part of the connecting ring 101.

[0059] After grinding, the connecting ring 101 is transferred to the third placement seat 81 of the assembly device 8 via the conveying device 4. Simultaneously, the first clamping and transferring assembly 83 clamps and transfers the connecting post 102 output from the second feeding device 3 onto the third placement seat 81. Then, the third limiting assembly 82 moves to limit the connecting ring 101, and the first pressing assembly 84 presses the connecting ring 101 and the connecting post 102. Finally, the pressed workpiece 10 is transferred to the inspection and discharge device 9 via the conveying device 4 to check whether the pressed workpiece 10 is qualified. Qualified workpieces 10 are then output from the discharge plate 95 into the finished product box. This process achieves a series of automatic operations for the connecting ring 101 and connecting post 102, including feeding, positioning, punching, grinding, assembly, and inspection and discharge. Compared with traditional manual and semi-automatic production methods, this significantly improves production efficiency, reduces human error, and ensures the stability and consistency of product quality. The close cooperation between the various devices forms a complete automated production line, reducing production costs.

[0060] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
